JP5943501B2 - Card lock for bag - Google Patents

Description

  The present invention relates to a card lock for a bag, and more particularly, to a card lock for a bag that is attached under a handle of a bag and can be locked and unlocked by pushing a card key and unlocked with a TSA key.

  Conventionally, there is a center lock attached under the handle of the bag as a kind of lock for the bag. In particular, the TSA center lock can be forcibly unlocked with the TSA key to inspect the contents of the travel bag at customs. The TSA key is a special key that TSA (Transportation Security Administration) holds to maintain security. If the number of the center lock fixed to the travel bag is shifted from the unlocking number, it will be locked. When the number lock is set to the unlock number and the knob is turned, the lock is released. When inspecting at customs, unlocking the cylinder lock with the TSA key will invalidate the number lock, and turning the knob will unlock it.

  In a normal lock, the key is inserted and rotated to unlock the lock. Alternatively, as in the case of a padlock, an operation of simply closing the shackle is performed when locking, and an operation such as rotation is performed after inserting the key when unlocking. There is also a lock that moves the lever after inserting the key. As described above, the lock that is unlocked by performing a plurality of operations with one hand or both hands can be reliably locked, but the operation is troublesome. To avoid that, there is a lock that can be locked and unlocked simply by pressing the key. It is very convenient because it can be locked and unlocked by a single operation with one hand. There is no need to rotate the key or slide the card key. Thus, the operation of locking and unlocking has been simplified. Examples of related art related to this will be given below.

  The “card lock for slide fastener” disclosed in Patent Document 1 is such that when the slider of the slide fastener is locked / unlocked with the card key, the card key is inserted only into the insertion slot. It prevents wear and damage and improves its durability. As shown in FIG. 10A, the cylinder is pushed against the first spring by inserting the card key into the insertion groove. As the cylinder moves forward, it moves forward in the same direction by the repulsive force of the second spring, and the latch engages the protrusion of the slide fastener slider. By holding the advanced position of the cylinder and inserting the card key again and pushing the cylinder slightly, the knock type locking mechanism releases the holding state and moves the cylinder back.

  The “trunk lock with a card lock lock” disclosed in Patent Document 2 prevents intrusion of dust from an insertion port of a card type key and prevents it from being locked when unlocked. As shown in FIG. 10B, in the card lock lock, the cylinder is rotatably held in the cylinder guide. An operation pin is inserted and held in the cylinder. The cylinder guide holds a locking pin and a pin spring at the locking position of the cylinder, and a second locking pin and a pin spring at the unlocking position, respectively. A shutter is attached to the card-type key insertion slot at an angle of about 60 degrees with respect to the key insertion groove via a shutter spring. Insert the key while pushing the shutter at the slope of the tip of the card type key.

  The “card type lock” disclosed in Patent Document 3 is simple in operation, robust in structure, and high in safety. As shown in FIG. 10 (c), when the card key is inserted from above, the cam projection and the slit of the card key coincide with each other, and the base of the lower end of the cam is opened. The long shaft fitted in can be pushed, whereby the slider can be pushed to the left, and the locking body of the lock body can be rotated by 90 degrees with the ratchet, and the lock can be locked or unlocked. Even if a sharp thin object is inserted through the key insertion window and tries to play with the lock actuating member, the lock actuating member cannot be tampered with because it moves through the slit of the link and enters the slit of the plate.

  Patent Document 5 discloses “a bag provided with a non-contact actuated locking mechanism” utilizing a wireless key that is easy to use for locking and unlocking operations. As shown in FIG. 10 (d), the recorded specific information can be called by irradiating a radio key such as an ID card with electromagnetic waves. Whether the information from the wireless key is the same as the predetermined specific information is determined by the specific information identifying means. When the identification signal is input to the electric lock actuating means, the locking lock member is alternately displaced to the locked position or the unlocked position. The power interrupt circuit turns on the power switch based on the identification signal, and turns off the power switch after a predetermined time. A mechanical unlocking means is provided for the malfunction of the locking mechanism.

  The “dial lock with operation wheel” disclosed in Patent Document 5 is a dial lock used for a bag lock, which is easy to operate and has clear numerical instructions. As shown in FIG. 10 (e), the lock is provided with a dial lock with an operation wheel as a center lock. It is a lock that uses a key. There is a dial with a code number on the outer peripheral surface. There are control wheels that are larger in diameter than the dial and integrated with the dial. There is a window where you can see the numbers on the dial. There is a hole where the control wheel is exposed. By attaching the operation wheel, it is only necessary to see one number in the window where the number can be seen, and the indication of the number becomes clear. Moreover, since the dial is not operated directly, there is no possibility that the outer peripheral surface is soiled or the numbers disappear due to wear.

  The “composite dial lock” disclosed in Patent Document 6 unlocks an unspecified number of locked dial locks with one common key. As shown in FIG. 10 (f), there are a plurality of dial numbers loosely fitted on the dial shaft. There is a dial lock having a locking plate for attaching and detaching a fastener. There is a cylinder lock with a cam that can be operated with a common key. The dial lock and the cylinder lock are attached so that one end of the dial shaft of the dial lock can be cam-engaged with the cam of the cylinder lock. The dial lock is unlocked by setting the lock plate of the dial lock to either the dial number dialing operation or the key cam operation.

  The “zipper lock” disclosed in Patent Document 7 can be reliably locked by downsizing and can be unlocked with a TSA key. As shown in FIG. 11 (a), the annular portion of the zipper puller is locked with the slide claw in the locking restraint portion of the zipper lock. When the number lock is locked, the lock bolt is lowered, stopping the movement of the stopper and preventing the slide claw from moving. When the number lock is unlocked, the lock bolt is raised and the slide claw can slide without being blocked by the lock bolt, so that the zipper puller can be released from the slide claw by turning the knob. When unlocked with the TSA key, the movable regulator moves backward and the stopper moves backward. Since the slide claw can slide, you can turn the knob to release the zipper puller from the slide claw.

  The “cylinder lock number lock” disclosed in Patent Document 8 is a TSA lock that can easily return the forced unlocked state to the normal locked state. As shown in FIG. 11B, when the number lock is locked, the rotary knob is locked. Can be unlocked by matching the number of the number lock. Turn the handle of the rotary knob to unravel the bag and open the bag. A cylinder lock is in the cylinder and is engaged with the cylinder by a tumbler. With the forced unlocking key, the cylinder lock can be disengaged. When the cylinder lock is unlocked, the lock of the rotary knob becomes invalid and the bag can be opened. The cylinder is provided with a slope portion that can return the tumbler from the forced unlocking position to the normal position. Even if the bag is returned while the cylinder lock is forcibly released, turning the cylinder lock with a screwdriver will return the cylinder lock to the normal position.

  The “center lock for bags” disclosed in Patent Document 9 does not cause an abnormal state no matter how the TSA key is operated. As shown in FIG. 11 (c), by matching the numbers of the number locks, the opening / closing rotary knob can be turned to unlock. According to the locking of the number lock, the rotation knob is prevented from rotating. When the cylinder lock is unlocked with the TSA key, the engagement with the rotary knob is released and it rotates, the link part is slid in the opening direction, and the locking handle for opening and closing the bag is opened. A rotation limiting mechanism is provided so that the cylinder lock rotates only within a range of 90 degrees between the normal locked state and the TSA unlocked state with respect to the rotary knob. Since the cylinder lock does not normally rotate in the locking direction from the unlocked state, it is not accidentally locked with the TSA key. Further, since a link limiting mechanism for limiting the movement of the link portion is provided so as not to rotate in the excessive unlocking direction from the normal unlocked state, the lock is not damaged by turning in the excessive unlocking direction.

  The “zipper lock” disclosed in Patent Document 10 is a TSA lock for a travel bag that is small and can be easily operated. The connecting hole of the back plate of the zipper lock is coupled to the head of the first slider of the zipper. As shown in FIG. 11 (d), when the head of the second slider of the zipper is inserted and pressed into the lock window of the zipper lock, the head is elastically sandwiched between the two locking balls and temporarily moved. It is fastened. When the cylinder lock is locked with the key, the cannula slides, the lock arm enters between the leaf spring and the side wall of the main body, and the lock ball does not move, so the head cannot be removed. The locked state and unlocked state are displayed on the display window. If the master key of the cylinder lock is a TSA key, it can be used as a TSA lock. Since the zipper lock also serves as a puller, it is small. Since it can be temporarily fixed and removed simply by pushing or pulling the zipper lock, it is easy to operate.

The slider 3 is provided with a tumbler so as to move only when a regular card key is inserted, and is a member that drives a toggle mechanism when moved by being pushed by the card key. The code hole 4 is a hole or a depression unique to the card key. The tumbler 5 is provided corresponding to the hole of the card key, and is a pin that allows the slider to move only in the case of a regular card key. The tongue plate 6 is a locking member attached to the lid of the heel. The bar 7 is a locking member that is driven by a toggle mechanism via a barb spring, and a hook part at the tip engages the tongue plate. This is a seesaw type mechanism having a driving end portion for forced unlocking on the opposite side of the hook portion that engages with the tongue plate, and is forcibly unlocked by pushing the driving end portion.

  The toggle mechanism 8 is a mechanism that is driven by a slider and alternately shifts between a locked state and an unlocked state, and drives the bar through a hook spring. The hook spring 9 is an elastic member that pushes the bar depending on the state of the toggle mechanism. The extruding part 10 is a member that is driven by a TSA cylinder lock and pushes the bar in the unlocking direction against the elasticity of the barb spring. The TSA cylinder lock 11 is a rotary cylinder lock that, when unlocked by the TSA key, pushes the driving end of the club through the pushing portion to forcibly unlock it. The state display window 12 is a window for displaying a locked / unlocked state.

  The function and operation of the bag card lock in the first embodiment of the present invention configured as described above will be described. First, an overview of the bag card lock will be described with reference to FIG. Insert the card key 1 into the slot 2. The card key 1 is a flat resin plate or metal plate with a plurality of holes, or a flat bar-shaped metal with a plurality of recesses. A plurality of tumblers are provided corresponding to the code holes 4 of the card key 1, and the slider can be moved in the card key insertion direction when a regular card key 1 as a combined key is inserted. The slider moves by being pushed by the tip of the card key 1.

  The toggle mechanism alternates between a locked state and an unlocked state. When the slider is pushed in the unlocked state, the unlocked state is entered. When the slider is pushed in the locked state, the state changes to the unlocked state. The locked toggle mechanism pushes the hook spring, the hook spring pushes the hook, and the hook engages with the tongue plate of the lid of the bag to close the lid. Whether the locked state or the unlocked state is displayed in the state display window 12. At the push-out part of the rotary TSA cylinder lock 11, the locked bar can be forcibly moved to the unlocked position against the elasticity of the spring and can be unlocked with the TSA key.

  Next, the internal structure of the bag card lock will be described with reference to FIGS. A TSA cylinder lock 11 is mounted on the back plate. Moreover, the toggle mechanism 8, the slider 3, and the club 7 are also attached through the holder. A tumbler 5 is attached to the slider 3. The tumbler 5 corresponds to the code hole 4 of the card key 1. The slider 3 is linked with the toggle mechanism 8, and each time the slider 3 moves, the toggle mechanism 8 rotates 1/4 by the ratchet. The disk and pusher also turn 1/4. The slider 3 is also linked to the bar 7 via a toggle mechanism 8 and a bar spring. The spring is not shown.

  The slider 3 is always urged upward (card key side) by a holding spring (not shown). Further, the tumbler 5 is locked to the holder so as not to move. When the key is inserted, the tumbler 5 moves and disengages, and moves downward (back plate direction). When the card key 1 is pushed, the toggle mechanism 8 transitions. The state shown in the figure is a state in which the card key 1 is inserted in the locked state and has not been pushed in yet.

  In the unlocked state, since the bar 7 is not pressed by the bar spring, it is raised in the upward direction (card key direction). The tongue plate on the lid can freely enter and exit the window on the back plate of the card lock for the bag. Even if the TSA cylinder lock 11 is operated in this state, of course, nothing changes. However, if the TSA cylinder lock 11 is in the forced unlocked state, it cannot be locked even if it is locked with the card key 1. In the locked state, the bar 7 is pushed by the barb spring and hangs down (back plate direction). The tongue plate of the lid is fixed to the window of the back plate of the card lock for the bag and cannot enter and exit freely.

  The TSA cylinder lock 11 is linked to the club 7 at the drive end. When the TSA cylinder lock 11 rotates, the driving end of the club 7 is pushed downward (backward) by the pushing part, and the hook of the club 7 moves upward (card) against the elasticity of the spring. (Key direction). The club 7 moves like a seesaw and is forcibly unlocked. In this example, the extruding part is a slope on the side surface of the cylinder.

  Next, the operation of the bag card lock will be described with reference to FIG. 5 (a) to 5 (d) are conceptual diagrams schematically showing the mechanism of the card lock for a bag. The slider 3 is biased upward by a holding spring (not shown). A plurality of tumblers are provided corresponding to the code holes of the card key, and the slider 3 can be moved in the card key insertion direction when a regular card key is inserted. Therefore, it is omitted. As shown in FIG. 5 (a), in the unlocked state, the hook portion at the left end of the scissors bar 7 is detached from the tongue plate 6 of the scissors lid, so that the scissors lid can be opened. When a regular card key is inserted, the slider 3 can be pushed in as shown in FIG. When the slider 3 is pushed, the toggle mechanism 8 transitions to the locked state. Since the toggle mechanism 8 is also well known, details are omitted.

  By making the movement of the toggle mechanism 8 visible, the locked state can be displayed. A character, symbol, or color indicating the unlocked state is drawn on the circumference of the rotating disk of the toggle mechanism 8, and the status is displayed each time the disk rotates 1/4 according to the card key insertion operation. Make the characters that display the unlocked state visible in the window. However, the disk status display is not linked to forced unlocking. Other well-known status display mechanisms may be employed. For example, the position of the stick 7 may be indicated to display the unlocked state.

  In the locked state, the hook spring 9 is pushed downward by the pushing portion of the toggle mechanism 8, and the hook portion at the left end of the stick 7 is lowered and engages the tongue plate 6. The hook spring 9 is rotatably held by a spring shaft. The club 7 is rotatably held by a rotating shaft. Even when the card key is pulled back, as shown in FIG. 5C, the locked state of the toggle mechanism 8 is maintained. When a proper card key is inserted and pushed in the locked state, the slider 3 moves down as shown in FIG. 5D, and the toggle mechanism 8 changes to the unlocked state. In the unlocked state, the hook spring 9 is returned, the hook portion at the left end of the stick 7 is raised, and the tongue plate 6 is released. Even if the card key is pulled back, the unlocked state of the toggle mechanism 8 is maintained as shown in FIG.

  Next, with reference to FIG. 6, the operation in the case of forcibly unlocking the bag card lock with the TSA key will be described. As shown in FIG. 6 (a), when the card lock for hooks is in the locked state, the pushing portion 10 of the TSA cylinder lock 11 is raised. Since the structure of the TSA cylinder lock 11 is well known, details are omitted. When the TSA cylinder lock 11 is turned with the TSA key, the pushing portion 10 is lowered as shown in FIG. The pushing portion 10 pushes the drive end portion of the right end of the rod 7 down against the elasticity of the rod spring 9, so that the hook portion at the left end of the rod 7 is raised and the tongue plate 6 is released. Although it is not displayed in the status display window that it is in the forced unlocked state, it can be seen from the direction of the TSA cylinder lock 11 whether it is in the forced unlocked state or the normal state.

  As described above, in the first embodiment of the present invention, the cardboard lock for the bag is locked by pressing the card key and locking the tongue plate of the bag lid with the hook portion of the pin through the slider, toggle mechanism and hook spring. The card key is pressed again to unlock, and the TSA key is used to lift the hook of the club against the elasticity of the hook spring, so that the lock is forcibly released. The available card lock can be a TSA lock.

  In the second embodiment of the present invention, the card key is pushed in, the stick is slid through the slider and the toggle mechanism, the hook plate of the lid is locked, the card key is pushed in again, the unlocking is performed, and the TSA key is used for the hook spring.

It is a locking member that is driven in the locking direction and slides to disengage from the hook plate. The hook plate is a locking member attached to the lid of the bag. There is a driving end for forced unlocking on the opposite side of the hole engaging with the hook plate, and the driving end is pushed to forcibly unlock. The toggle mechanism 8 is a mechanism that is driven by a slider, and alternately shifts between a locked state and an unlocked state, and slides the club with a pushing portion of the disk. The barb spring 9 is an elastic member that pushes the bar in the locking direction. The extruding part 10 is a member that is driven by a TSA cylinder lock and pushes the bar in the unlocking direction against the elasticity of the barb spring. Other members are the same as those in the first embodiment.

  The function and operation of the bag lock for bag according to the second embodiment of the present invention configured as described above will be described. First, an overview of the bag card lock will be described with reference to FIG. The external appearance of the bag card lock for Example 2 is almost the same as that of Example 1 shown in FIG. The second embodiment is different from the first embodiment in that the club 7 is structured to slide in a direction orthogonal to the moving direction of the card key. The process up to inserting the card key and rotating the toggle mechanism disk 1/4 is the same as in the first embodiment.

  Although not shown in FIG. 7, the hook spring always pushes the bar 7 in the locking direction. Since the hook spring of the second embodiment simply pushes the bar 7, adjustment of the spring constant is easier than that of the first embodiment. When the toggle mechanism 8 is in the locked state, the bar 7 is pushed to the innermost position by the bar spring and is in the locked state, and the bar 7 can be engaged with the hook plate of the lid of the bag to close the lid. When the toggle mechanism 8 is in the unlocked state, the pushing part of the disk of the toggle mechanism 8 pushes the bar 7 in the unlocking direction, so that the bar 7 is detached from the hook plate of the lid of the bar and the lid can be opened. Whether it is locked or unlocked is displayed in the status display window. It is possible to unlock with the TSA key by forcibly moving the locked bar 7 to the unlocked position against the elasticity of the spring at the pushing part of the rotary TSA cylinder lock 11.

  Next, the unlocking / unlocking operation of the card lock for the bag will be described with reference to FIG. As shown in FIG. 8 (a), in the unlocked state, the club 7 is pushed to the left by the toggle mechanism 8, and the hole of the club 7 is detached from the hook plate of the lid. Can open the lid of the bag. The relationship between the hole of the club 7 and the hook plate is shown in a view of the back side. When the regular card key is inserted, as shown in FIG. 8B, the disk of the toggle mechanism 8 rotates, and the bar 7 is pushed by the barb spring 9 and moves to the right. In the locked state, as shown in FIG. 8C, the bar 7 moves to the right end, and the hole of the bar 7 engages with the hook plate of the lid of the bar. When the TSA cylinder lock 11 is opened with the TSA key in the locked state, the pushing portion 10 of the TSA cylinder lock 11 rotates and pushes the right end of the club 7 so that the club 7 moves to the left and the club 7 The hole part of this part comes off the hook plate of the lid of the bag.

  Next, with reference to FIG. 9, a method for locking and unlocking the card lock for the bag will be described. FIGS. 9A to 9D are conceptual diagrams schematically showing the mechanism of the card lock for a bag. The slider 3 is biased upward by a holding spring (not shown). A plurality of tumblers are provided corresponding to the code holes of the card key 1, and the slider 3 can be moved in the card key insertion direction when the regular card key 1 is inserted. Since it is a thing, it is abbreviate | omitting.
