Description

  • The present invention relates to a locking system for the locking/unlocking of doors or the like and, more specifically, to a system for the locking/unlocking of doors or the like having a cylinder/key lock type, subordinated to an electronic control unit known with the name of "Transponder".
  • Systems for the locking/unlocking of locks subordinated to an unit of the "Transponder" type are already known to the art. Usually, such systems provide further to the cylinder lock apted to engage with coded key, a first transmitter unit to transmit an access code, such transmitter unit being coupled to the key body, and a second receiving unit for the receiving of an actuation/disactivation code, such receiving unit being coupled to the lock cylinder. Such systems provide that, once the actuation code has been recognized and validated from the receiving unit, the latter outputs a signal that, when processed by a data processing unit, gives the consent to activate other related electronic or electrical devices. For instance, such systems are widely used as antitheft devices in the vehicles locks through a connection with the EEPROM ignition control unit.
  • However, such systems are exclusively appliable where an electronic data processing unit is already available, as they interact creating an electronic lock and not a mechanical one.
  • Moreover, a locking system is known from the US Patent 5.826.450 in the name of Codatex ID-Systeme GmbH comprising a locking device consisting of a key and of a rotating lock cylinder set. The rotating lock cylinder is rotatably mounted in a casing wherein a mechanical actuator is placed and apted to engage with the cylinder so as to lock/release the rotation of the latter even if the key is inserted. The motion of the mechanical actuator is ensured by an electric actuator and by a power supply internally placed in said cylinder casing.
  • The main drawback of such type of device of the state of the art is that the mechanical actuator provides a single locking member that can be susceptible to breaking when the cylinder is forcibly rotated. It is to be understood that once the locking member has been broken, the lock behaves like a normal rotating cylinder lock, therefore not providing an improved protection with respect to the analogous cylinder locks of the state of the art.
  • Another drawback of such device is that the power supply is housed inside of the cylinder casing. This means that when any kind of intervention needs to be performed, e.g. the periodical battery replacement, it is necessary to disinstall the device from the housing where it is placed in order to reach the batteries housing. This entails an useless waste of time, as well as the intervention of skilled personnel with further inconveniences for the user.
  • Thus, the object of the present invention is that of solving such drawbacks of the locks of the prior art providing an improved rotatable cylinder type mechanical lock for doors, windows or the like, associated to a "Transponder" type unit having an independent power supply and such as to make the "Lock-Transponder" set suitable for any application in which a cylinder lock is provided or needed, as well as making the system of easy deploy and maintenance.
  • Hence, according to the present invention, a locking system for the locking/unlocking of locks in doors, windows and the like is provided, comprising a cylinder body, a front panel and a rear panel, characterised in that it further comprises:
  • first means for cooperating with cam means to enable the locking/unlocking of said lock;
  • connection means of said first means to said cam means; and
  • actuator means of said connection means;
  • the arrangement being such that, following to the activation of said actuator means the said connection means are apted to move from a first non-operative condition, wherein there is no connection between said first means and said cam means, and a second operative condition, wherein said first means are connected to said cam means.
  • The detailed description of a preferred embodiment of the present invention will be provided hereinafter, given by way of example and not for limitative purposes, by making reference to the annexed drawings wherein:
  • figure 1 is an assembly view of the locking system of the present invention;
  • figure 2 is a view of the logical circuit diagram of the system components of the present invention;
  • figure 3 is a partial sectional view of the locking system of the present invention;
  • figures 4(a) and 4(b) are cross-sectional partial views taken along section lines A-A and B-B of figure 3, respectively; and
  • figure 5 is a block diagram of the logical function of the system of the present invention.
  • With reference to figure 1, it is schematically shown the locking system of the present invention. According to the invention, the locking system provides a key 1 having a handgrip region 2 which incorporates a remotely controlled data transmitter unit 3 (not in the figure). The key 1 is suitable for engaging in the known manner with a respective cylinder body 4 mounted inside of a door frame, window or the like (not in figure). The body 4 has at the central part thereof a rotating cam element 5 suitable for being rotated by the key 1 and for engaging with a lock inside the door frame wherein the system is mounted (not shown and better illustrated hereinafter).
  • At the front portion of the cylinder body 4, i.e. wherein the key 1 is to be inserted, a front panel 6 is integrally mounted and being apted to contain a first antenna 7 for the activation of the data transmitter unit 3 placed in the key 1, and a first plurality of functional members apted to the operation of the system of the present invention (better illustrated hereinafter). Likewise, at the rear portion of the cylinder body 4, i.e. at the opposite side of the one for the insertion of the key 1, a rear panel 8 is mounted, the latter being apted to house a second antenna 9 ed a second plurality of operative members (better illustrated hereinafter).
  • Further, a second key 10 is rotatably mounted onto the rear panel 8, and connected to the cylinder 4 in the manner better illustrated hereinafter. It has to be pointed out that the front panel 6 is suitable for being mounted towards the outside of the door or window whereto the locking system of the present invention is applied, while the rear panel 8 is apted to be mounted on the inside of the door or window whereto it is associated.
  • With reference now to figure 2, it shows the circuit scheme of the locking system of the present invention.
  • According to the invention, the front panel 6 has on its inside the antenna 7 for transmitting an actuation field to the remote unit 3. Further, a two-coloured LED 11, apted to visually signalling the system status and a buzzer 12 to acoustically signalling the system status are provided. Furthermore, a power supplying outlet 13 is provided to energize the system from the outside when needed.
  • Onto the rear panel 8 on the inside thereof, besides the antenna 9 for the activation of the remote unit 3, a power supply 14 for energizing the system is provided. Likewise, a two-coloured LED 15 and a buzzer 16 are provided to signal the system status inside the ambient.
  • All the members on the front panel 6 and rear panel 8 are circuitally connected to a data processing unit 17 suitable for operating and controlling the system operative logic. Further, the data processing unit 17 is circuitally connected with an electromechanical actuator 18 mounted inside the cylinder body 4 (better illustrated hereinafter).
  • With reference now to figure 3, it shows the assembly of the cylinder body 4 according to the system of the present invention. Inside the cylinder body 4 a combination cylinder member 19 is provided for the engagement with the key 1 in the already known manner. The inner end of the cylindrical member 19 has integrally mounted thereon a toroidal shaped projecting member 20 having two diametrically opposed hollow regions (or grooves) 21 (better illustrated hereinafter).
  • As it will be better understood hereinafter, the cam element 5 has a substantially cylindrical hollow shape and is apted to slidingly engage inside thereof with the outer surface of the toroid member 20. Further, the same has grooves 51 as well and positioned diametrically opposed and at the inner perimetral portion thereof (better illustrated hereinafter).
  • At the rear portion of the cylinder body 4 a second member 30 of an elongated cylindrical shape is rotatably mounted. The member 30 has a first outer end 31 externally and integrally connected with the key 10 onto the rear panel 8, and a second inner end 32 that is apted to slidingly engage with the inner portion of the cam member 5. Likewise, the inner end 32 has a toroidal shape as well, with two diametrically opposed inner keyway regions 33.
  • The cylindrical member 30 is hollow, and inside thereof a pin 34 is slidingly housed. The pin 34 is apted to slide coaxially with respect to the member 30 according to the direction of the arrow F1 in the figure. At the inner end 32 of the cylindrical member 30, the pin 34 has a bush member 35 slidingly mounted onto the former. Between the bush member 35 and the pin 34 an helical spring 36 is placed, in order to exert a reciprocal spacing force (better illustrated hereinafter).
  • Further, the pin 34 has a passing key-pin 37 for guiding the pin 34 inside the cylindrical member 30 by means of suitable seats. The key-pin 37 is connected at the bottom thereof with a connecting annular rod member 38 which, in turn, is connected to an end of a lever 39 pivoted onto the main body of the cylinder 4. At the opposed end of the lever 39, the same is hinged to the electromechanical actuator 18 so as to be movable the former in the direction of the arrow F2.
  • The arrangement of the actuator 18, lever 39 and pin 34 is such that to each motion of the actuator 18 in the direction of the arrow F2 there is a related and opposed motion of the pin 34 inside of the cylindrical member 30 in the direction of the arrow F1.
  • With reference now to figures 4(a) and 4(b), two partial cross-sectional views are illustrated therein, taken along the section lines A-A and B-B, respectively, of figure 3.
  • As it can be better understood, the bush 35 being slidable in the axial direction of the body of the cylinder body 4, it is apted to engage slidingly in the grooves 51 of the cam 5 as well as in the grooves 21 of the toroid 20 and in the regions 33 of the member 30.
  • As it can be understood from the figures, according to the position assumed by the bush 35, it is possible to rotatably connect the cylinder 19, and therefore the key 1 to the cam 5, or the cylindrical member 30 and therefore the key 10, to the cam 5.
  • The function of the spring 36 will be disclosed hereinafter. According to the angular position of the cylinder 19, the grooves 21 of the inner end 20 thereof are aligned or not to the respective grooves 51 of the cam 5. This means that only when both the grooves 21 and 51 are perfectly aligned, the bush 35 can slide under the biasing of the pin 34 until connecting the cylinder 19 to the cam 5.
  • Otherwise, when the key 1 is inserted in the cylinder 19 and the latter has performed a partial rotation with respect to the cam 5, the cylinder 19 cannot be connected to the cam 5 via the bush 35. Being the bush 35 slidingly mounted onto the pin 34, this enables the advance towards the toroid member 20 only of the pin 34 against the action of the spring 36, even if the bush 35 cannot advance due to the misalignment of the grooves 21 and 51.
  • In this condition, the cylinder 19 can rotate without dragging the cam member 5 until the following alignment of the regions 21 and 51 where the biassing of the spring 36 makes the bush 35 to slidingly advance in the aforesaid region 21, thus performing the connection between key 1 and cam 5. At this stage, the key 1 can lock/unlock the lock associated to the cylinder 4. The withdrawal of the pin 34 after an action of the actuator 18 causes a withdrawal of the bush 35 from the cam 5 disconnecting the same from the cylinder 19, thus performing the disconnection of the key 1 from the cam 5, consequently disabling the cylinder 4 from the outside until the next connection between the cylinder 19 and the cam 5.
  • Likewise, the aforesaid description of the connection/disconnection between cam 5 and cylinder 19 is appliable for what concerns the connection between cylindrical member 30, i.e. the key 10, and the cam 5. It must be noted here that, when the cylinder 19 is disconnected from the cam 5, the latter is connected to the cylindrical member 30, that is with the key 10, thus enabling the use of the cylinder body 4 only from the inside. Vice versa, by disconnecting the key 10 from the cam 5 the connection of the latter with the cylinder 19 is obtained, thus enabling the use of the cylinder 4 only from the outside.
  • With reference now to figure 5, the operational logic of the locking system of the present invention is shown.
  • With reference to the diagram in figure 5, the system of the present invention has the following operative phases:
  • Sleep. The system shall usually remain in a half-functioning condition ensuring the minimal electric absorption (such state will otherwise be defined as Sleep state).
  • Stand-by The insertion of key 1 causes the closing of an electric contact, due to which the system shall step to an active state (such state shall otherwise be defined as stand-by state). In such condition the system shall perform the charge checking of the batteries 14, and shall send an RF supply field and search the Transponder Unit. In the case wherein the supply voltage is below TBD Volts, the system shall step to the low battery state. Moreover, the system shall signal the stand-by state turning on the red-lighted LED 11 and 15. In case of a recognition failure after TBD" the system shall step to the warning state.
  • Unlock Once recognized the Transponder unit the system shall immediately operate the electromechanical device 18 (such state shall otherwise be defined as unlock state), and break the RE emissions. Moreover, the system shall signal the unlock state by turning on the green-lighted LED 11 and 15. The operative time of the electromechanical actuation device 18 will be set to TBD msec.
  • Check The system shall check the performed actuation of the electromechanical device 18, i.e. a cutoff of a contact internal to the cylinder (such state will otherwise be defined as check state). In case of no cutoff of the contact after TBD msec from the start of the unlock condition, the system shall step to the warning state.
  • Lock The extraction of the key 1 causes the cutoff of an electrical contact, due to which the system shall immediately operate the electromechanical actuator 18 in an direction opposite with respect to the unlock state (such state will otherwise be defined as lock condition). The break of the power supply to the actuator 18 will occur at the closing of the contact internal to the cylinder of the preceding phase. In case of failure to close the contact after TBD sec in the lock condition, the system shall step to the warning state.
  • Low battery In the case provided during the Stand-by condition, the system shall signal a low charge state of the battery 14 intermittently operating the buzzer 12 or 16 and the red-lighted LED 11 and 15 at TU' intervals for a TBD" total time (such state will otherwise be defined as low battery condition).
  • Switch- Off The system must be disconnectable with a button, but exclusively in the unlock state, with the key 1 being inserted and recognized (such state will otherwise be defined as Switch-off condition). The system restarting takes place with the same button and the system steps in following stand-by condition.
  • Warning In the cases provided during the Stand-by, Check and Lock conditions the system shall signal a warning state operating the intermittent green/red-lighted LED 11 and 15 at TBD" intervals and the buzzer 12 or 16 continuously (such state will otherwise be defined as warning condition).
