Description

Padlocks to hold and secure zipper pulls

technical field

The utility model relates to a padlock and a lock system, more particularly to a padlock configured to hold and fix a zipper pull.

Background technique

Various padlock structures have been developed and widely adopted by individuals to prevent unauthorized access to any particular item or area that has been closed and locked. While many locks are configured to be opened by a key, a variety of combination lock configurations have been developed that are opened by knowledge of a specific number.

One particular type of combination lock that is very popular because of its ease and convenience of use is the combination lock that employs a plurality of rotatable individual dials, each dial forming one of indicia (usually numbers or letters), these The dial includes the number used to unlock the lock. Typically, combination locks have one mode or position where a user can set or reset a desired number sequence. While locks of this general nature have been used for decades and constructed in a variety of forms and shapes, these prior art combination lock constructions have common deficiencies that have not been successfully overcome.

In most prior art constructions, combination padlocks incorporate a J-shaped or U-shaped shackle for providing the desired engagement with the suitcase or item to be locked. In one of the most common applications, to hold a suitcase in a fixed and locked position, a shackle is inserted through an aperture formed in a zipper pull mounted to the suitcase. While most suitcases or similar products (which incorporate a zipper for holding their mating parts in a closed position) are locked by the owner using a padlock incorporating a J-shaped or U-shaped shackle, a group of products that have become popular these days are A lock structure designed to independently receive and secure two separate and independent zipper pulls mounted on a suitcase or similar product. In this way, a suitcase or similar product can be securely locked using a padlock structure that is more easily incorporated into the main body of the suitcase (in contrast to a separate and independent element that hangs from the product).

Although combination padlocks configured to receive and secure zipper pulls directly therein incorporate structures that can be easily distinguished from prior art padlocks incorporating conventional shackles, prior art regarding rotatable dial/shackle padlocks The technical issues are generally equivalent to the prior art issues regarding rotatable dial/zipper pull padlocks. As a result, many manufacturers have attempted to solve the problems associated with rotatable dials or combination locks.

One of the major difficulties and deficiencies that have not been overcome in these prior art structures is the structure that ensures that the user cannot accidentally or unintentionally alter or change the preset number without his knowledge. In this case, when a user unknowingly alters or alters a known number, the entire combination lock will not work since the user typically cannot release the shackle from locking engagement with the housing. for further use.

In addition, although key-operated locks do not have the difficulty of changing or altering numbers without the user's knowledge, users often cannot use key-operated locks due to lost or misplaced keys. As a result, prior art key operated locks are also often discarded because the user cannot locate the specific key to operate the lock.

Another common problem that has plagued prior art structures has been the cost to manufacture and assemble prior art padlocks, whether the padlock is key operated or combination operated. In order to obtain a padlock that provides all of the features desired by consumers, prior art structures often incorporate multiple small parts, each of which requires an expensive assembly process to make the final product. As a result, these prior art lock structures are more expensive to manufacture, thereby reducing the ability of these locks to reach a broad base of consumers.

Another common problem with prior art padlocks is that these prior art structures do not prevent contaminants from reaching the rotatable internal components of the lock, thereby damaging them or interfering with individuals who know the actual number or have the actuating key. Ease of operating the lock. Although many attempts have been made to reduce the adverse effects caused by contamination reaching these components, these attempts have not completely eliminated the problem.

Another final difficulty that has arisen recently and affects both combination locks and key-operated locks is the requirement that, in order to gain access to luggage considered suspicious, customs officers and/or inspection or security personnel must break all locked locks. Under the new security regulations that have been implemented, all luggage must be scanned or inspected to prevent the carriage of potentially dangerous goods or products deemed undesirable. In these cases, when the luggage is scanned and requires further visual inspection, the inspector has the right to open the luggage for visual inspection, which includes physically breaking any locks that may be present on the luggage.

Thus, with these new regulations now in effect, all prior art locking systems that cannot be opened by inspectors and/or security personnel are physically broken in order to gain access to any luggage requiring visual inspection. As a result, consumers are now faced with the possibility that any locking system employed to secure the contents of the suitcase can be physically removed by security personnel, leaving the luggage completely unsecured for the remainder of the trip.

In addition, another new regulation was implemented that requires lock manufacturers who manufacture key-operated locks for use by security personnel to implement a structure that allows the key to be removed while the lock is in the open position. This additional regulation complicates the construction of prior art padlocks and adds additional difficulties to the usual operation of key operated padlocks.

Additionally, some prior art padlocks are configured to provide a double locking system that allows security personnel to gain access to the lock if necessary. However, these prior art double lock padlock systems are generally limited to padlocks incorporating J-shaped or U-shaped shackles. There have not been double locking padlocks configured to secure a zipper pull to a locking system such that these padlocks are susceptible to being broken by security personnel whenever inspection of suitcases employing these locks is required.

Detailed ways

The structure and operation of three alternate preferred embodiments of the dual mode zipper slider locking system 10 of the present invention are best understood with reference to FIGS. 1-40B and the following detailed description. However, various changes can be made to the present invention without departing from the scope of the present invention. Therefore, it should be understood that the following detailed descriptions of the embodiments shown in FIGS. 1 to 36 are provided for exemplary purposes only, and are not intended to limit the present invention.

Three alternate preferred embodiments of the dual mode zipper slider locking system 10 of the present invention are shown in FIGS. 1-40B , each utilizing a minimum number of major components to achieve dual mode locking. system and also substantially reduces the complexity found in most prior art locking systems. In this way, the present invention provides an efficient and commercially desirable structure that can be manufactured at a competitive cost, while also providing the unique properties of the present invention and all of the locking normally contained in prior art locking systems and anti-theft features.

As fully detailed herein, embodiments of the present invention incorporate uniquely structured interconnected control panels and mating components for controlling the movement of locking bolts that are compatible with the locking system of the present invention. The zipper pulls of any product are securely engaged. By employing the structures detailed herein, an easily manufacturable, efficient dual mode locking system is achieved that provides all of the properties expected in an efficient, competitively priced zipper pull locking system.

In this embodiment of the invention, one of the main components forming the zipper locking system 10 is the housing 12 incorporating the zipper slider receiving areas 14 , 15 . As is well known in the art, in the usual construction of any zipper employed on suitcases, briefcases and other similar products, two separate and independent zipper pulls are employed to allow the zipper to be opened and closed from multiple alternate positions . Additionally, each zipper pull incorporates a sheet, usually formed of plastic or metal, in which an enlarged opening or hole is formed. By utilizing holes formed in each zipper slider, the locking system of the present invention is capable of securely engaging each zipper slider at a separate retention area, thereby keeping the zipper slider fully locked and secured to the housing 12 of the locking system 10 .

In addition, each of the three alternative embodiments of the present invention incorporates a number control lock 17 and a key control lock 18 , both housed in the housing 12 . Additionally, as will be fully detailed in the description below, the key-operated locking portion 18 and the number-operated locking portion 17 are configured in such a way that they can independently actuate the cooperating locking plate and slider mounted in the housing 12. to move the associated zipper slider locking latch in a direction to release the zipper slider secured thereto. In this way, embodiments of the present invention provide secure locking and controlled release of each of the two zipper pulls by actuating the number control lock or the key control lock when desired.

In a first preferred embodiment of the present invention, as shown in FIGS. 1 to 13 , a zipper slider locking system 10 incorporates zipper slider locking latches 80 and 90 in addition to the components described above. As shown and described herein, zipper locking latch 80 is configured to move independently relative to zipper receiving area 14 , while zipper locking latch 90 is configured to move independently relative to zipper receiving area 15 . To this end, the zipper slider locking latches 80 and 90 are all configured to move laterally into and out of the area defined by the receiving areas 14 and 15 so that each zipper slider locking latch 80 and 90 can be formed with the Apertures in the associated zipper slider securely engage to securely retain the zipper slider to the housing 12 while also disengaging the zipper slider from it if desired to release.

As clearly shown in all of the drawings, the zipper slider locking latches 80 and 90 each include an elongated, longitudinally extending integral portion mounted in the housing 12 to enable the latches 80 and 90 to move in a desired controlled orientation. sports. To this end, the zipper slider engagement elements 85 and 95 are formed as part of the latches 80 and 90 and represent components of the latches 80 and 90 that are inserted directly into holes formed in the zipper pull for controlling the zipper when desired. Locking engagement and release of the slider. The remaining structure of latches 80 and 90 is used to provide the desired movement of zipper pull engagement elements 85 and 95 .

As will be more fully detailed below, each time a zipper slider is inserted into the zipper receiving areas 14 and 15, the zipper engagement elements 85 and 95 are automatically advanced into locking engagement with the aperture of each zipper slider. This self-locking engagement is achieved by the biasing force provided by spring members 160 and 170 acting on latch members 80 and 90 .

In order to achieve the desired controlled movement of the zipper slider locking latches 80 and 90, the locking system 10 incorporates the control board 60 as the primary element for achieving the desired movement. As shown and will be described in more detail below, the control plate 60 effectively prevents any lateral movement of the zipper slider locking latches 80 and 90 in the locked position, while whenever the control plate 60 moves out of the block with the latches 80 and 90 When in relation, the latches 80 and 90 are enabled to move laterally.

To this end, whenever the key is used to control the locking portion 18, the flange 111 of the plate 110 of the barrel 100 is pivoted arcuately into direct contact with a portion of the control plate 60 so that the control plate 60 is free from contact with the latches 80 and 90. The latches 80 and 90 can move within the housing 12 by moving out of the locking engagement. Additionally, once this unlocking has been achieved, the radially extending arm 112 of the plate 110 of the barrel 100 directly contacts the latch 80 so that both latches 80 and 90 move within the housing 12 to engage the zipper pull. Both elements 85 and 95 move out of engagement with the associated zipper pull. In this way, the zipper pull is immediately released in response to the arcuate pivoting movement of the barrel 100 .

Additionally, as will be more fully detailed below, whenever the number control lock 17 is used, the slider assembly 50 is moved to directly control the movement of the control plate 60 to release the blocking of the latches 80 and 90 . Additionally, when the control board 60 has moved out of the blocking relationship with the latches 80 and 90, continued movement of the slider assembly 50 results in direct contact with the latches 80 and 90 so that the latches 80 and 90 are in contact with the housing. 12, thereby effectively releasing the locking engagement of the zipper slider engagement elements 85 and 95 with the associated zipper slider. In this way, in response to input of a predetermined number in the number control lock portion 17, the zipper slider is immediately released.

As can be seen from the foregoing detailed description, by employing either the number control lock 17 or the key control lock 18, the zipper slider engagement elements 85 and 95 of the lock latches 80 and 90 are controlled release when desired, thereby allowing the Any zipper pull on the lock is disengaged from the locking system 10 to open a suitcase, briefcase or other product. Additionally, as will be more fully detailed below, when desired, the user can insert a zipper pull of a desired product into locking system 10 to securely engage the zipper pull in system 10 to achieve a desired lock therewith. join each other.

In the preferred structure of this embodiment of the present invention, the number control locking part 17 includes a plurality of marking bearing rotatable dials 21, 22 and 23 for setting and inputting the parameters for locking and unlocking the zipper slider locking system 10. expected number. In order to enable a user to easily display any desired number, the housing 12 preferably includes a display area formed thereon for easy viewing of indicia formed on the rotatable dial. In general, the structure of the number control locking portion 17 is similar to that detailed in US Pat. No. 6,408,660, the relevant parts of which are incorporated herein by reference.

As shown, the rotatable dials 21 , 22 and 23 are each mounted in cooperating association with a clutch ring 31 , 32 or 33 . Additionally, to maintain clutch rings 31, 32, and 33 in frictional engagement with dials 21, 22, and 23, spring members are coaxially associated with each assembly to provide continuous frictional engagement for each clutch ring with its associated dial. required bias force. In this way, rotational movement of dials 21 , 22 and 23 about their central axes causes clutch rings 31 , 32 and 33 to move rotationally therewith.

Although the detailed construction and operation of dials 21, 22 and 23, and associated clutch rings 31, 32 and 33 are fully detailed below and in U.S. Pat. No. 6,408,660, one structural feature that should be Grooves 31 a , 32 a and 33 a in each clutch ring 31 , 32 and 33 . As detailed herein, the respective slots 31 a , 32 a and 33 a of the respective clutch rings 31 , 32 and 33 in conjunction with the rotation of the dials 21 , 22 and 23 control the locking and unlocking of the system 10 .

To provide the desired locking and controlled release of the zipper slider from the zipper engagement elements 85 and 95 whenever the number control lock 17 is used, the number control lock 17 incorporates a locking plate 40 . In its preferred construction, locking plate 40 incorporates fingers 41 , 42 and 43 each aligned with one of the slots 31 a , 32 a and 33 a formed in clutch rings 31 , 32 and 33 . In addition, the locking plate 40 is continuously biased by the spring members 121 and 122 into engagement with the clutch rings 31, 32 and 33 so that whenever the slots 31a, 32a and 33a are aligned with the fingers 41, 42 and 43, the locking plate 40 Automatically moves into engagement with the clutch ring.

When all three slots are arranged in aligned relationship with all three fingers (this is only achieved when the desired preset number has been entered on the rotatable dials 21, 22 and 23), the locking plate 40 due to the applied Automatic movement by spring force on it. However, whenever an incorrect number is entered on the dials 21, 22, and 23, one or more of the grooves 31a, 32a, and 33a of the associated clutch rings 31, 32, and 33 are located in relation to the associated fingers of the locking plate 40. A position where one of the pieces 41, 42 and 43 is misaligned. As a result, the locking plate 40 cannot move, thereby maintaining the locking system 10 in the locked position.

Once the locking plate 40 has moved within the housing 12, the flange 44 of the locking plate 40 is moved out of blocking engagement with the gap or cutout area 51 of the slider assembly 50, as described above. As a result, slider assembly 50 is released to enable lateral movement within housing 12 .

In a preferred construction, the locking system 10 incorporates a button 140 secured to the slider assembly 50 by a screw 131 as shown in the figures. As a result, once the locking plate 40 is moved, the user can utilize the button 140 to move the slider assembly 50 laterally within the housing 12 . As the slider assembly 50 moves laterally, the sloped edge surface 52 of the slider assembly 50 contacts the sloped edge surface 61 of the control board 60 . The engagement of these two inclined surfaces causes the control plate 60 to move in a direction towards the locking plate 40 and dials 21 , 22 and 23 so that the blocking edges 62 and 63 of the control plate 60 clear the side walls of the locking latches 90 and 80 . 91 and 81 broke away.

Additionally, as slider assembly 50 continues to move laterally within housing 12 , after contacting and moving control board 60 , edges 53 and 54 of slider assembly 50 contact surfaces 92 and 82 of locking latches 90 and 80 . In a preferred construction, edge 53 is configured to be spaced a distance 55 from surface 82 and edge 54 is spaced a distance 56 from surface 92 . Due to this construction, a built-in delay zone is formed to allow the inclined surface 52 of the slider assembly 50 to contact the control board 60 and effect the desired movement of the control board 60 before any contact of the edges 53 and 54 with the locking latches 80 and 90 .

As a result, the blocking engagement of the control board 60 with the locking latches 80 and 90 is released prior to any contact of the slider assembly 50 with the latches 80 and 90 . As such, latch members 80 and 90 are capable of lateral movement within housing 12 against the biasing spring force of spring members 160 and 170 in response to engagement with slider assembly 50 . As a result, the zipper slider engagement elements 85 and 95 move away from their associated zipper sliders, effectively releasing the locking engagement of the zipper with the housing 12 .

In a preferred construction, the zipper locking system 10 also incorporates two blocking plates 70 , each associated with a locking latch 80 and 90 and one of its zipper engaging elements 85 and 95 . In addition, as shown in the figures, each blocking plate 70 is associated with a spring 150 that continuously exerts a biasing force on the blocking plate 70 in a direction towards the zipper slider engaging elements 85 and 95 . As a result, whenever the locking latches 80 and 90 are moved to the release position such that the zipper slider engaging elements 85 and 95 are withdrawn from their associated zipper sliders, the blocking plate 70 causes the zipper sliders to pop out and be automatically released therefrom.

Additionally, to this end, side edge 71 of blocking plate 70 contacts surfaces 83 and 93 of zipper slider engaging elements 85 and 95 of locking latches 80 and 90 as shown, thereby preventing any movement of latches 80 and 90 .

Due to this construction, only when the zipper joint is inserted in the zipper receiving areas 14 and 15 and the blocking plate 70 is moved downwards, the side edges 71 of the blocking plate 70 are moved out of engagement with the surfaces 93 and 83 of the locking bolts 90 and 80 , the locking latches 80 and 90 are able to move back to their locked positions. Once the blocking engagement is released, the locking latches 80 and 90 automatically move back into engagement with the zipper pull due to the biasing force applied by the springs 160 and 170 .

Additionally, any desired number may be set on the dials 21 , 22 and 23 prior to insertion of the zipper pull in the locking system 10 . By holding the button 140 in the open position as detailed above, with the locking plate 40 engaged with the clutch ring, the user can turn the dials 21, 22 and 23 to set any desired indicia as a number.

In addition to using a number to control the locking part 17 to open the locking system 10, the locking system 10 can also be opened by using a key to control the locking part 18. The structure and operation of the locking and unlocking system 10 using the key-operated locking portion 18 is best understood with reference to FIGS. 1-13 and the following detailed description. Additionally, it should be understood that alternative configurations of the key-operated lock 18 may be employed without departing from the scope of the present invention. However, the preferred structures are fully detailed here for exemplary purposes only.

In this configuration, the key-operated lock portion 18 of the housing 12 of the locking system 10 incorporates a cylinder 100 mounted in a receiving cavity formed in the housing 12 and configured so that whenever The barrel 100 can pivot in an arc when the correct key is inserted into the receiving slot of the barrel 100 . To this end, the barrel 100 incorporates a pivot arm structure that can be aligned in exactly the desired configuration whenever a mating key is inserted in its receiving slot. Once inserted, pivotal movement of the cartridge 100 is achieved.

As shown, the barrel 100 incorporates a cam plate 110 mounted at its distal end configured to pivot arcuately simultaneously with the arcuate movement of the barrel 100 in response to insertion and use of the correct key component. sports. As a result, whenever the correct key is inserted into the receiving groove formed in the barrel 100 and the barrel 100 is pivoted with the key, the cam plate 110 is pivoted simultaneously therewith.

As noted, in a preferred construction, the cam plate 110 incorporates a radially extending flange portion 111 and a radially extending arm member 112 . When the correct key is inserted into the cylinder 100, by using the key to rotate the cylinder 100, this causes the cam plate 110 to rotate simultaneously therewith. This rotation causes the flange portion 111 to pivot and come into contact with the finger 64 of the control board 60 . Additionally, continued movement of barrel 100 forces fingers 64 to move with it, thereby moving control plate 60 within housing 12 towards dials 21 , 22 and 23 . This movement disengages the edges 62 and 63 from blocking engagement with the side walls 91 and 81 of the locking latches 80 and 90 .

As the barrel 100 continues to rotate due to the continued rotation of the key therein, the arm 112 of the cam plate 110 contacts the lips 94 and 84 of the locking bolts 90 and 80 . This contact and continued movement causes the locking latches 90 and 80 to move within the housing 12 and cause the zipper engagement elements 95 and 85 to withdraw from the zipper pull, thereby causing the zipper pull to eject freely and the blocking plate 70 to move into contact with the element 95. Join with 85.

In a preferred configuration of this embodiment, the key can be removed from the barrel 100 while the system 10 is in the unlocked mode. While most prior art padlock configurations prevent key removal in unlocked mode, the present invention allows key removal, thereby meeting the new regulations of security agencies.

In Figs. 14 to 23, a second preferred embodiment of the zipper slider locking system 10 of the present invention is shown. The structure and operation of this second preferred embodiment can be best understood by referring to the drawings and the following detailed description. Additionally, as is apparent from this disclosure, a minimum number of major components are employed, thereby achieving a zipper pull locking system that also substantially reduces the complexity found in most prior art systems. In this way, the present invention provides an efficient and commercially desirable structure that can be manufactured at a competitive cost, while also providing the unique properties of the present invention and all of the locking normally contained in prior art locking systems and anti-theft features.

As noted above, embodiments of the present invention all incorporate uniquely configured interconnected control panels and mating components for controlling the movement of a locking bar that is compatible with the zipper of any product employing the locking system of the present invention. The sliders are securely engaged. By employing one of the structures detailed herein, an efficient, easily manufacturable dual mode locking system is achieved that provides all of the properties expected in an efficient, competitively priced zipper pull locking system.

In this embodiment of the invention, one of the main components forming the zipper locking system 10 is the housing 300 which incorporates the zipper slider receiving areas 14 , 15 . As is well known in the art and as mentioned above, in the usual construction of any zipper used on suitcases, briefcases and other similar products, two separate and independent zipper pulls are employed to allow the zipper to be pulled from multiple alternate positions open and closed. Additionally, each zipper pull incorporates a sheet, usually formed of plastic or metal, in which an enlarged opening or hole is formed. By utilizing holes formed in each zipper slider, the locking system of the present invention is able to securely engage each zipper slider at a separate retention area, thereby keeping the zipper slider fully locked and secured to the housing 300 of the locking system 10 .

In addition, this embodiment of the present invention is also combined with a number control locking part 17 and a key control locking part 18 , both of which are accommodated in the housing 300 . Additionally, as will be fully detailed in the description below, the key-operated locking portion 18 and the number-operated locking portion 17 are configured in such a way that a cooperating locking plate mounted in the housing 300 can be actuated independently to enable The associated zipper slider latch moves in a direction to release the zipper slider secured thereto. In this way, all embodiments of the present invention provide secure locking and controlled release of each of the two zipper pulls by actuating the number controlled lock or the key controlled lock when required. Additionally, in this second preferred embodiment, the zipper pulls can be individually controlled so that one zipper pull is released without releasing the other.

In a second preferred embodiment of the present invention, as shown in FIGS. 14 to 23 , the zipper slider locking system 10 incorporates zipper slider locking latches 360 and 370 in addition to the components described above. As shown and described herein, the zipper locking latch 360 is configured to move independently relative to the zipper receiving area 14 and the zipper locking latch 370 is configured to move independently relative to the zipper receiving area 15 . To this end, the zipper slider locking latches 360 and 370 are configured to move laterally into and out of the area defined by the receiving areas 14 and 15 so that each zipper slider locking latch 360 and 370 can be formed with The holes in the associated zipper sliders securely engage, thereby holding the zipper sliders securely on the housing 300 while also being disengageable from one of the zipper pulls when it is desired to release it.

As best shown in all of the figures, zipper slider locking latches 360 and 370 each include an elongated longitudinally extending plate mounted in housing 300 to enable movement of latches 360 and 370 in opposite directions. To this end, zipper slider engagement elements 365 and 375 are formed as part of latches 360 and 370 and represent components of latches 360 and 370 that are inserted directly into holes formed in the zipper pull for controlling the zipper when desired. Locking engagement and release of the slider. The remaining structure of latches 360 and 370 is used to provide the desired movement of zipper slider engagement elements 365 and 375 .

As will be more fully detailed below, each time a zipper slider is inserted into the zipper receiving area 14 and 15, the zipper engagement elements 365 and 375 are automatically advanced into locking engagement with the aperture of each zipper slider. This self-locking engagement is achieved by the biasing force provided by spring members 420 and 430 acting on latch members 360 and 370 .

In order to achieve the desired controlled movement of the zipper slider locking latches 360 and 370, the locking system 10 is provided with a control plate 340 in combination with a blocking element 350 as the main element for achieving the desired movement. As described and will be described in more detail below, the blocking element 350 effectively prevents any lateral movement of the zipper slider locking latches 360 and 370 in the locked position, while the blocking element 350 is free from blocking with the latches 360 and 370. Moving out of the relationship enables the latches 360 and 370 to move laterally inwardly.

To this end, whenever the locking portion 18 is controlled with a key, the arm 391 of the cam plate 390 of the barrel 400 pivots in an arc to come into direct contact with a portion of the control plate 340 so that the control plate 340 is laterally out of contact with the blocking element 350. Blocking movement out of engagement. Once the control plate 340 has moved a sufficient distance, the blocking element 350 is automatically moved into a cavity formed in the plate 340 due to the spring 400 , thereby enabling the latches 360 and 370 to be manually moved within the housing 300 by the user. Additionally, once the user moves either or both of the latches 360 and 370, the zipper slider engagement elements 365 and 375 are moved out of engagement with the associated zipper slider. In this way, the zipper pull is released immediately.

Additionally, as will be more fully detailed below, whenever a number is used to control locking portion 17, locking plate 330 is moved to directly control movement of control plate 340, thereby releasing blocking member 350 and making latches 360 and 370 movable. When the control plate 340 has moved out of the blocking relationship with the blocking element 350, the blocking element 350 automatically moves into the receiving area of the plate 340 to effectively release the latches 360 and 370, thereby allowing the latches to be manually actuated by the user. The member moves, thereby effectively releasing the locking engagement of the zipper slider engagement elements 365 and 375 with the associated zipper slider. In this way, in response to input of a predetermined number in the number control lock portion 17, the zipper slider is immediately released.

As can be seen from the foregoing detailed description, by employing either the number control lock 17 or the key control lock 18, the zipper slider engagement elements 365 and 375 of the lock latches 360 and 370 are controllably released when desired so that Any zipper pull on the zipper can be disengaged from the locking system 10 to open suitcases, briefcases or other products. Additionally, as will be more fully detailed below, when desired, the user can insert a zipper pull of a desired product into locking system 10 to securely engage the zipper pull in system 10 to achieve a desired lock therewith. join.

In the preferred structure of this embodiment of the present invention, the number control locking part 17 includes a plurality of mark bearing rotatable dials 321, 322 and 323 for setting and inputting the parameters for locking and unlocking the zipper slider locking system 10. expected number. In order to enable a user to easily display any desired number, the housing 300 preferably includes a display area formed thereon for easy viewing of indicia formed on the rotatable dial. In general, the structure of the number control locking portion 17 is similar to that detailed in US Pat. No. 6,408,660, the relevant parts of which are incorporated herein by reference.

Rotatable dials 311 , 312 and 313 are each mounted in mating association with a clutch ring 321 , 322 or 323 as shown. Additionally, to maintain clutch rings 321, 322, and 323 in frictional engagement with dials 311, 312, and 313, spring members are coaxially associated with each assembly to provide the means for maintaining each clutch ring in continuous frictional engagement with its associated dial. required bias force. In this way, rotational movement of dials 311 , 312 and 313 about their central axes causes clutch rings 321 , 322 and 323 to rotationally move therewith.

Although the detailed construction and operation of dials 311, 312, and 313, and associated clutch rings 321, 322, and 323 are fully detailed below and in U.S. Patent 6,408,660, one structural feature that should be Grooves 321 a , 322 a and 323 a are incorporated in 321 , 322 and 323 . As detailed herein, the slots 321a, 322a, and 323a of the respective clutch rings 321, 322, and 323, in conjunction with the rotation of the dials 311, 312, and 313, control the locking and unlocking of the system 10.

To provide the desired locking and controlled release of the zipper slider from the zipper engagement elements 365 and 375 whenever the number control lock 17 is used, the number control lock 17 incorporates a locking plate 330 . In its preferred construction, locking plate 330 incorporates fingers 331 , 332 and 333 each aligned with one of the slots 321 a , 322 a and 323 a formed in clutch rings 321 , 322 and 323 . In addition, locking plate 330 is continuously biased by spring member 410 into engagement with clutch rings 321, 322, and 323, thereby automatically moving locking plate 330 whenever slots 321a, 322a, and 323a are aligned with fingers 331, 332, and 333. into engagement with the clutch ring.

When all three slots are arranged in aligned relationship with all three fingers (this is only achieved when the desired preset number has been entered on the rotatable dials 311, 312 and 313), the locking plate 330 due to the applied Automatic movement by spring force on it. However, whenever an incorrect number is entered on the dials 311, 312, and 313, one or more of the grooves 321a, 322a, and 323a of the associated clutch rings 321, 322, and 323 are located in relation to the associated fingers of the locking plate 330. A position where one of the members 331, 332 and 333 is misaligned. As a result, locking plate 330 cannot move, thereby maintaining locking system 10 in the locked position.

As mentioned above, once the locking plate 330 has been moved within the housing 300, the bearing area 334 of the locking plate 330 moves with it, causing the control plate 340 to also move. As shown, the control plate 340 is biased by the spring 450 to hold it in its initial position, as shown in FIG. 16 . However, when the locking plate 330 is moved due to entering the correct preset number on the dials 311, 312 and 313, the locking plate 330 causes the control plate 340 to move with it since the end of the control plate 340 is captured in the carrying area 334 .

As shown, movement of the control plate 340 moves the cutout region 342 of the control plate 340 into alignment with the blocking element 350 . As the blocking element 350 is biased by the spring 400 to move toward the control plate 340 , movement of the cutout area 342 into alignment with the blocking element 350 allows the blocking element 350 to move into the cutout area 342 . As a result, edges 352 and 353 of blocking member 350 are released from blocking engagement with edges of latches 360 and 370 , thereby enabling movement of latches 360 and 370 within housing 300 .

In this embodiment of the invention, each latch 360 and 370 includes a plate whose surface is separately exposed at the top of the housing 300 . As a result, once the blocking element 350 is moved, each latch 360 and 370 can be individually moved into the housing 300 by the user sliding the latch 360 and/or 370 inwardly, as detailed above. This movement moves zipper slider engagement elements 365 and 375 out of engagement with the retained zipper slider, thereby releasing the zipper slider. As a result, the user is able to release one zipper pull or both zipper pulls individually when desired.

In a preferred construction, the zipper locking system 10 also incorporates a spring plate 380 associated with the locking latches 360 and 370 and their zipper engaging elements 365 and 375 . Additionally, spring plate 380 is continuously biased in a direction toward zipper slider engagement elements 365 and 375 . As a result, whenever the locking latches 360 and 370 are moved to the release position such that the zipper slider engaging elements 365 and 375 are withdrawn from their associated zipper sliders, the spring plate 380 causes the zipper sliders to eject and automatically release therefrom.

Additionally, as spring plate 380 is moved upwards, its side edges 381 and 382 move between surfaces 361 and 371 of housing 300 and zipper pull engagement elements 365 and 375, thereby preventing locking latches 360 and 370 from returning to their original positions. Location.

Due to this construction, only when the zipper puller is inserted into the zipper receiving areas 14 and 15 and the spring plate 380 moves downward, the side edges 381 and 382 of the spring plate 380 are released from engagement with the surfaces 361 and 371 of the locking latches 360 and 370 Once moved out, the locking latches 360 and 370 can only be moved back to their locked positions. Once the blocking engagement is released, the locking latches 360 and 370 automatically move back into engagement with the zipper pull due to the biasing force applied by the springs 420 and 430 .

As mentioned above, the preset number can be changed as desired each time the number control locking portion 17 of the locking system 10 is in its open or unlocked position. Once the locking plate 330 is moved laterally within the housing 300 by the spring 410 , the receiving area 335 is aligned with the button 460 . By advancing the button 460 into the receiving area 335, the locking plate 330 is held in the unlocked or open position.

By fixing this open position, the user can rotate the dials 311, 312 and 313 to any desired position to display a specific number. Once the number is set, the user removes the retaining force so that the spring 470 forces the button 460 out of the receiving area 335 .

In addition to using a number to control the locking part 17 to open the locking system 10, the locking system 10 can also be opened by using a key to control the locking part 18. The structure and operation of the system 10 for locking and unlocking using the key controlled locking portion 18 can be best understood with reference to FIGS. 14-23 and the following detailed description. Additionally, it should be understood that alternative configurations of the key-operated lock 18 may be employed without departing from the scope of the present invention. However, the preferred structures are fully detailed here for exemplary purposes only.

In this configuration, the key-operated lock portion 18 of the housing 300 of the locking system 10 incorporates a cylinder 440 mounted in a receiving cavity formed in the housing 300 and configured so that whenever The barrel 440 pivots in an arc when the correct key is inserted into the receiving slot of the barrel 440 . To this end, barrel 440 incorporates a pivot arm structure that can be aligned in exactly the desired configuration whenever a mating key is inserted in its receiving slot. Once inserted, pivotal movement of the barrel 440 is achieved.

As shown, the barrel 440 incorporates a cam plate 390 mounted at its distal end configured to pivot arcuately simultaneously with the arcuate movement of the barrel 440 in response to insertion and use of the correct key component. sports. As a result, whenever the correct key is inserted into the receiving groove formed in the barrel 440 and the barrel 440 is pivoted with the key, the cam plate 390 is pivoted simultaneously therewith.

As noted, in a preferred construction, the cam plate 390 incorporates radially extending arms 391 . When the correct key is inserted into the cylinder 440, by using the key to rotate the cylinder 440, this causes the cam plate 390 to rotate simultaneously with it. This rotation rotates the arm 391 with it and forces the beveled or beveled edge of the arm 391 into contact with the beveled/beveled edge 343 of the control plate 340 . As barrel 440 continues to rotate, arm 391 forces edge 343 and control plate 340 to move laterally within housing 300 against the biasing force of spring 450 .

As the control plate 340 continues to move, the wall 341 moves out of blocking engagement with the edge 351 of the blocking element 350 . Additionally, the cutout area 342 becomes aligned with the blocking element 350 , thereby being forced into the cutout area 342 due to the spring 400 . Due to the increased loading area 334 of the locking plate 330 , the control plate 340 is able to move without interfering with the locking plate 330 .

Once the blocking element 350 enters the cutout area 342 of the control panel 340, the sides 352 and 353 of the blocking element 350 release the blocking relationship with the latches 360 and 370 so that the latches 360 and 370 can be opened by a user when desired. Additionally, once the zipper pull is removed, the key inserted into barrel 440 can be removed, thereby meeting new safety regulations.

In Figs. 24 to 40B, a third preferred embodiment of the zipper slider locking system 10 of the present invention is shown. The structure and operation of this third preferred embodiment is best understood with reference to the figures and detailed description that follows. Additionally, as is apparent from this disclosure, a minimum number of major components are employed, thereby achieving a zipper pull locking system that also substantially reduces the complexity found in most prior art systems. Thus, the present invention provides an efficient and commercially desirable structure that can be manufactured at a competitive cost while providing the unique properties of the present invention and all of the locking and locking features typically contained in prior art locking systems. Anti-theft features.

As noted above, all embodiments of the present invention incorporate uniquely structured interconnected control panels and mating components for controlling the movement of a locking bar that is compatible with any product employing the locking system of the present invention. Zipper pulls engage securely. By employing one of the structures detailed herein, an efficient, easily manufacturable dual mode locking system is achieved that provides all of the properties expected in an efficient, competitively priced zipper pull locking system.

In this embodiment of the invention, one of the main components forming the zipper-pull locking system 10 is the housing 500 incorporating the two zipper-pull receiving areas 14 , 15 . As is well known in the art and as mentioned above, in the usual construction of any zipper used on suitcases, briefcases and other similar products, two separate and independent zipper pulls are employed to allow the zipper to be pulled from multiple alternate positions open and closed. Additionally, each zipper pull incorporates a sheet, usually formed of plastic or metal, in which an enlarged opening or hole is formed. By utilizing holes formed in each zipper slider, the locking system of the present invention is capable of securely engaging each zipper slider at a separate retention area, thereby keeping the zipper slider fully locked and secured to the housing 500 of the locking system 10 .

In addition, this embodiment of the present invention is also combined with a number control locking part 17 and a key control locking part 18 , both of which are accommodated in the housing 500 . Additionally, as will be fully detailed in the description below, the key-operated locking portion 18 and the number-operated locking portion 17 are configured in such a way that they can independently actuate a mating locking plate and sliding door mounted in the housing 500. to move the associated zipper slider latch in a direction that releases the zipper slider secured thereto. In this way, all embodiments of the present invention provide secure locking and controlled release of each of the two zipper pulls by actuating the number controlled locking portion or the key controlled locking portion when required.

In a third preferred embodiment of the present invention, as shown in FIGS. 24 to 36 , the zipper slider locking system 10 incorporates zipper slider locking latches 590 and 600 in addition to the components described above. As shown and described in detail herein, zipper locking latch 590 is configured to move relative to zipper receiving area 14 , while zipper locking latch 600 is configured to move relative to zipper receiving area 15 . To this end, the zipper slider locking latches 590 and 600 are configured to move laterally into and out of the area defined by the receiving areas 14 and 15, so that each zipper slider locking latch 590 and 600 can be formed with the Apertures in the associated zipper slider securely engage to securely retain the zipper slider to the housing 500 while also enabling disengagement of the zipper slider therefrom when desired.

As clearly shown in all of the drawings, the zipper slider locking latches 590 and 600 each include an elongated, longitudinally extending integral portion mounted in the housing 500 to enable the latches 590 and 600 to move in a desired controlled orientation. sports. To this end, the zipper slider engagement elements 595 and 605 are formed as part of the latches 590 and 600 and represent components of the latches 590 and 600 that are inserted directly into holes formed in the zipper pull for controlling the zipper when desired. Locking engagement and release of the slider. The remaining structure of the latches 590 and 600 serves to provide the desired movement of the zipper slider engagement elements 595 and 605 .

As will be more fully detailed below, each time a zipper slider is inserted into the zipper receiving area 14 and 15, the zipper engagement elements 595 and 605 are automatically advanced into locking engagement with the aperture of each zipper slider. This self-locking engagement is achieved by the biasing force provided by the spring member 670 acting on the latch members 590 and 600 .

In order to achieve the desired controlled movement of the zipper slider locking latches 590 and 600, the locking system 10 incorporates the control board 580 as the primary element for achieving the desired movement. As mentioned and will be described in more detail below, the control plate 580 effectively prevents any lateral movement of the zipper slider locking latches 590 and 600 in the locked position, while whenever the control plate 580 is out of the way with the latches 590 and 600 Moving out of relationship enables latches 590 and 600 to move laterally.

For this reason, in order to best understand the cooperative relationship between the control plate 580 and the zipper slider locking latches 590 and 600, it is important to understand the cooperative blocking and releasing structures and interengaging relationship of the component parts that form part of these interrelated components. . To this end, as will be fully detailed below and as shown in FIGS. 24 to 36 and particularly in FIG. The blocking edge or wall 583. As will be detailed below, the blocking edges/walls 582/583 are positioned to cooperate with the side walls 591 and 601 of the latches 590 and 600.

As shown, these cooperating elements are positioned to block mutual engagement with each other when the control plate 580 is in its first position, and to be movable laterally relative to each other when the control plate 580 is in its second position. Additionally, control board 580 incorporates a cavity or slot 584 formed therein proximate post 588 , and a cavity or slot 585 formed adjacent post 587 . In a preferred construction, the cavity/slot 584/585 is sized such that the sidewall 591/601 can move freely therein, thereby allowing the latch 590/600 to move freely.

Whenever the user wants to use the number control locking part 17 of this embodiment of the present invention, a plurality of rotatable dials 521 , 522 and 523 bearing marks are used. As described above with respect to other embodiments, the rotatable dials 521 , 522 and 523 are used to set and enter the desired number for locking and unlocking the zipper pull locking system 10 . In order to enable a user to easily display any desired number, the housing 500 preferably includes a display area formed thereon for easy viewing of indicia formed on the rotatable dial. In general, the structure of the number control lock 17 is similar to that described above and detailed in US Patent 6,408,660, the relevant parts of which are incorporated herein by reference.

As shown, rotatable dials 521 , 522 and 523 are each mounted in cooperative association with a clutch plate or ring 531 , 532 or 533 . Additionally, to maintain clutch plates or rings 531, 532, and 533 in frictional engagement with dials 521, 522, and 523, spring members are coaxially associated with each assembly to provide continuous frictional engagement of each clutch ring with its associated dial. required bias force. In this way, rotational movement of dials 521 , 522 and 523 about their central axes causes clutch rings 531 , 532 and 533 to rotationally move therewith.

Although the detailed construction and operation of dials 521, 522, and 523, and associated clutch rings 531, 532, and 533, are fully detailed below and in U.S. Patent 6,408,660, one structural feature that is important to note is the Grooves 531a, 532a, and 533a are incorporated in rings 531, 532, and 533. As detailed herein, the slots 531a, 532a, and 533a of each clutch ring 531, 532, and 533 in combination with the rotation of the dials 521, 522, and 523 control the locking and unlocking of the system 10.

To provide the desired locking and controlled release of the zipper slider from the zipper engagement elements 595 and 605 whenever the number control lock 17 is used, the number control lock 17 incorporates a locking plate 540 . In its preferred construction, locking plate 540 incorporates fingers 541 , 542 and 543 that each align with one of slots 531 a , 532 a and 533 a formed in clutch rings 531 , 532 and 533 . Additionally, locking plate 540 is continuously biased by spring member 550 into engagement with clutch rings 531, 532, and 533, thereby automatically moving locking plate 540 whenever slots 531a, 532a, and 533a are aligned with fingers 541, 542, and 543. into engagement with the clutch ring.

Whenever all three slots are arranged in aligned relationship with all three fingers (this is only achieved when the desired preset number is entered on the rotatable dials 521, 522, and 523), the locking plate 540 due to Automatic movement by spring force applied to it. However, whenever an incorrect number is entered on the dials 521, 522 and 523, one or more of the slots 531a, 532a and 533a are located out of alignment with one of the associated fingers 541, 542 and 543. As a result, locking plate 540 cannot move, thereby maintaining locking system 10 in the locked position.

As noted above, once the locking plate 540 has moved within the housing 500 , the ball receiving area 544 of the locking plate 540 moves therewith to effectively align with the steel ball 560 . Once the receiving area 544 is aligned with the steel ball 560 , the ball 560 can drop into the receiving area 544 . This movement releases the blocking engagement of the steel ball 560 with the ball retaining area 571 of the slide plate 570 , allowing the slide plate 570 to move laterally within the housing 500 . As shown in Figure 37 and Figure 38, the steel ball as the blocking locking element can also be replaced by a roller-shaped element or a metal roller 560-02, which can also achieve the purpose of blocking through active engagement.

As shown in all the figures, the slide plate 570 preferably incorporates an actuation plate 620 which is securely attached to the slide plate 570 at one end thereof by a fastener 630 . Plate 620 is cooperatively associated with housing 500 so as to be easily accessible from its top surface. In this way, once the slide plate 570 is released, the user can quickly and easily controllably move the actuation plate 620 and the slide plate 570 when desired. Additionally, to maintain the slide plate 570 in its unactuated position, a spring member 574 is mounted in the housing 500 to bias the slide plate 570 to its unactuated position. However, by moving the actuating plate 620, the user is able to overcome the biasing force and move the slide plate 570 laterally within the housing 500 each time the steel ball 560 disengages from the retaining area 571 .

Whenever the sliding plate 570 moves against the biasing force of the spring member 574 , the inclined cam surface 572 contacts the inclined surface 581 of the control plate 580 . As a result, lateral advancement of slide plate 570 within housing 500 brings cam surface 572 into contact with ramp 581 of control plate 580 , effectively forcing control plate 580 upward within housing 500 . In a preferred construction, spring member 680 is mounted in biased relationship with control plate 580 to maintain control plate 580 in its initial position wherein ramp 581 engages cam surface 572 of slide plate 570 . However, whenever sliding plate 570 moves laterally within housing 500 , engagement of cam surface 572 with ramp 581 of control plate 580 forces control plate 580 to move against the biasing force of spring member 680 .

Once the control plate 580 is moved upwardly, the blocking edges 582 and 583 of the control plate 580 are out of blocking engagement with the side walls 591 and 601 of the zipper slider locking latches 590 and 600, as fully described above. In addition, the lateral movement of the sliding plate 570 also brings the upstanding protrusion or flange 573 of the sliding plate 570 into contact with the surfaces 592 and 602 of the locking latches 590 and 600 . Furthermore, as the protrusion/flange 573 of the sliding plate 570 contacts the surface 592/602, continued movement of the sliding plate 570 causes the locking latches 590 and 600 to move simultaneously therewith.

In a preferred construction, upstanding protrusions or flanges 573 are spaced apart from surfaces 592 and 602 of locking latches 590 and 600 . In this way, a built-in time delay is effectively implemented to ensure that the ramped cam surface 572 of the slide plate 570 will contact the ramp 581 of the control plate 580 to move the control plate 580 upwards before the protrusions/flanges 573 come into contact with the surfaces 592 and 602 . As a result, the desired controlled movement and cooperative operation of the interactions of these components is achieved.

As mentioned above, once the control plate 580 is moved up to its second position, the cavity or slot 584 formed adjacent to the post 588 and the cavity or slot 585 formed adjacent to the post 587 are aligned with the side walls 591 and 601 of the locking latches 590 and 600. allow. As a result, locking latches 590 and 600 are free to move laterally within housing 500, advancing side walls 591 and 601 into cavities/slots 584/585. Additionally, this lateral movement is readily achieved due to the contact and movement between the upstanding protrusion/flange 573 and the surfaces 592 and 602 of the latch 590/600.

As the protrusion/flange 573 comes into contact with the surface 592/602 of the latch 590/600, and further movement of the slide plate 570 moves the latch 590/600 with it, the zipper pull engagement element 595/605 is released and installed therein engagement of the zipper slider, thereby disengaging the zipper slider from locking engagement with the housing 500 . In addition, the release of the zipper slider from the zipper slider receiving area 14 and the holding area 15 also automatically moves the blocking plate 610 upward. This upward movement ejects the zipper slider from the housing 500 while also moving the blocking plate 610 into blocking alignment with the zipper slider engagement element 595/605, thereby preventing the latch 590/600 from returning to its original position.

As described above in other embodiments of the present invention, the blocking plate 610 is mounted in mating relationship with the zipper slider receiving area 14 and the retaining area 15, and the spring member 640 is matingly associated therewith so that when the zipper slider is removed therefrom, When the head is turned, the control blocking plate 610 moves upwardly into engagement with the blocking latch 590/600. In this way, the latches 590 and 600 remain in their open positions until the zipper slider returns to the receiving area 14 and the retaining area 15, inserting the zipper pull into the retaining/receiving area forces the blocking plate 610 to move downward against the biasing force of the spring member 640 , thereby releasing the latch 590/600 and enabling the engagement element 595/605 to be inserted into the hole of each zipper pull. In this way, the zipper pull is quickly and easily securely engaged with the housing 500 by the user when desired.

As shown in FIGS. 39A-40B , the sidewall flange 611 of the blocking plate 610 aligned with the engaging element 595/605 incorporates a horizontal surface 611-A and a vertical surface 611-B, wherein the vertical surface 611-B can be engaged with The elements 595/605 form a stop, and the slope between the horizontal plane 611-A and the vertical plane 611-B facilitates the lateral movement of the locking bolt and its engaging elements 595/605 during the locking operation.

Whenever the user wishes to set or reset a desired number on the dials 521, 522, and 523, the dials are positioned so that the slots 531a, 532a, and 533a of the clutch plates 531, 532, and 533 engage the fingers of the locking plate 540. 541, 542 and 543 are aligned. Once in this position, the locking plate 540 is automatically moved to engage the fingers in the corresponding slots. When in this position, the extension finger 545 of the locking plate 540 is moved out of blocking alignment with the return member 650 .

As shown in the figure, the return member 650 is provided in cooperation with the spring member to maintain the return member in the first position, wherein the return member 650 is spaced apart from the finger member 545 . However, once the locking plate 540 is moved to its clutch ring engaged position, the return member 650 can be moved against the biasing force of the spring member to move the wall portion 651 of the return member 650 into blocking engagement with the fingers 545 . When in the second position, locking plate 540 cannot move laterally so that slots or notches 531 a , 532 a and 533 a remain engaged with protrusions 541 , 542 and 543 .

Once this fully engaged position is achieved, the user can rotate the dials 521, 522 and 523 to any desired position to display any specific indicia in the display area, thereby constructing the desired number. Once the desired number is set, the reset member 650 is released and allowed to return to its original position so that the locking plate 540 can be moved out of engagement with the clutch rings 531 , 532 and 533 .

In addition to the locking system 10 of the present invention that can be opened by using a number to control the locking part 17 , the present invention enables the locking system 10 to be opened by using a key to control the locking part 18 . To this end, whenever a key is used to control the locking portion 18, the correct key part is inserted into the barrel 510 to pivot the barrel 510 arcuately about its central axis. Additionally, barrel 510 is cooperatively associated with cam plate 660 such that cam plate 660 arcuately pivots therewith.

In a preferred construction, the cam plate 660 incorporates radially extending flanges 661 and radially extending fingers 662, each arcuately spaced from each other. Additionally, the flange 661 is cooperatively associated with the wall portion 586 of the control board 580 . With this configuration, arcuate pivotal movement of the barrel 510 brings the flange 661 into contact with the wall portion 586 of the control plate 580, thereby lifting or moving the control plate 580 from its first position to its second position. As mentioned above, when the control plate 580 is in its second position, the side walls 591 and 601 of the locking latches 590 and 600 are aligned with the cavities/slots 584/585 of the control plate 580, thereby aligning the latches 590/600 relative to the its lateral movement.

Additionally, the radially extending fingers 662 of the cam plate 660 are configured for contact with the terminating edges 594 and 604 of the locking latches 590 and 600 . Additionally, the radial position of fingers 662 relative to flange 661 is configured to ensure that fingers 662 come into contact with terminating edges 594 and 604 only after control plate 580 has been raised to its second position.

Thus, the arcuate pivotal movement of the cylinder 510 brings the fingers 662 into contact with the terminating edges 594 and 604 of the latches 590 and 600 and causes the latches 590 and 600 to move relative to each other as the cylinder 510 continues the arcuate pivotal movement. Housing 500 moves laterally. In this way, any zipper slider installed in the zipper pull receiving areas 14 and 15 is easily and efficiently utilized with the key-operated locking portion 18 of the locking system 10 . Additionally, as described above, once the zipper slider is released, the blocking plate 610 automatically rises to eject the zipper slider from the receiving areas 14 and 15 while also effectively preventing the latches 590 and 600 from returning to the locked position.

As another feature of this embodiment of the invention, the key for arcuately pivoting the barrel 510 is configured to withdraw from the barrel 510 once the zipper pull is released from the housing 500 . In this way, the present invention is able to meet and comply with recently implemented regulations regarding the removal of the key from the cylinder during inspection.

It can be seen that the above-mentioned purpose clearly achieved in the foregoing is effectively achieved, and since certain changes can be made to the above-mentioned product without departing from the scope of the present utility model, all the above-mentioned items contained in the above description or shown in the accompanying drawings The subject matter should be regarded as exemplary rather than limiting.

It is also to be understood that the appended claims are intended to cover all generic and specific features described herein, and all statements of the scope of the invention which are expressly considered to be within the scope of the invention.
