Description

The invention relates to a cabinet closure with a housing and arranged therein by actuating a handle movable latch, with a Einsteckschacht for inserting a coin, with a scanning device for scanning the diameter of the inserted into the insertion slot into a scanning position coin, wherein the scanning device so with a locking device cooperates, that the bolt is displaceable only with a mating diameter having coin.

Such a cabinet lock is from the DE 198 32 516 A1 previously known. The previously known lock for a locking system has a housing, a displaceable in the housing of a handle latch, wherein the latch is held by means of a locking device in its back-closed position. This locking device is released to preclose the bolt when a coin is inserted into a plug-in slot, which has a suitable diameter. The lock has a scanning device for sensing the diameter of the coin. If the latch is closed again by actuating a handle, the coin falls into an output slot.

The DE 10 2006 034 292 describes a cabinet lock in which a key secret must be entered into a lock to the bolt lock. The key secret can be entered via a keyboard. The lock is also able to read a transponder in which the key secret is stored.

From the DE 195 15 765 A1 a coin deposit lock is known, which is used in shopping carts. The lock has a plug-in slot. By inserting the coin a lock is released.

The invention has for its object to further develop a generic cabinet closure nutzsvorteilhaft.

The object is achieved by the invention specified in the claims, each claim represents an independent solution to the problem and can be combined with any other claim.

First and essentially it is proposed that the scanning device forms a holding jaw, which holds the partially in the scanning position accessible from outside in the insertion slot coin with vorgeschlossenem bolt against pulling out. According to the coin is inserted into the insertion slot of the lock housing into a scanning position. In this scanning position, the scanning device scans the diameter of the coin. It is a maximum insertion depth, in which the coin is still accessible from the outside, but due to the holding function of the holding jaw can not be pulled out of the insertion slot. For this purpose, a positive retention of the coin is preferably provided in the scanning position. The coin is preferably gripped partially like a pliers, wherein a holding jaw is formed by a swing arm mounted pivotably about a housing-fixed axis. Another holding jaw can be firmly connected to the housing. The two holding jaws enclose the coin beyond its region of greatest diameter, so that it can only be pulled out again after the two holding jaws have moved away from the insertion shaft. With the coin itself is no operation of the bolt. The latter is preferably displaceable transversely to Münzeinsteckrichtung. The rocker preferably has a bearing leg, at the end of the axis is articulated. The holding jaw preferably protrudes substantially transversely from the bearing leg. The rocker forms a flanked by at least one locking flank tour recess. In this Tourenausnehmung a bolt associated to the touring pin can occur when a matching coin in the Plug-in shaft is inserted. At the Tourenausnehmung can join a guide groove. This extends with inserted matching coin substantially parallel to the bolt displacement direction. While the movable holding jaw extends substantially transversely to the bolt displacement direction, the bearing leg extends parallel to the displacement direction of the bolt. The stationary holding jaw can be relocated. It can be fixed, for example by means of screws on the lock housing. By loosening the screws, the distance between the two holding jaws in the release position can be adjusted. The insertion shaft preferably has a bulge, in which a portion of the inserted coin is located. The bulge extends over an area large enough for the coin to be grasped between two fingers to be pulled out of the insertion slot. The coin is inserted substantially only for Durchmesserabtastung in the insertion slot. During the insertion of the coin, only the locking device is moved from a blocking position to a release position. A bolt shift by the coin is not provided. In a development of the invention, the lock housing has a blocking element. The latter is accessible from the outside of the housing. This blocking element is able to fix the rocker or the Tourenausnehmung in a position in which the Tourenausnehmung lies in the path of movement of the touring pin. In the locked state, the lock can thus be operated without a deposit function. The blocking element may form a blocking pin, which engages in the blocking position in an end portion of the guide groove adjoining the touring recess so as to position-fix the rocker in the pivot position corresponding to the release position. The bar lock takes place in the known manner via a crank pin, which is actuated by a handle. This engages in an engagement opening of the bolt to vorschließ the bolt. The lock additionally has a locking device with which the bolt can be held in the pre-closed position. The locking device In addition, can also hold the bolt in the back-closed position. The locking device can be brought from a blocking position to a release position. This can be done in a known manner, for example by pressing a key. Preferably, however, the blocking device is released by reading an electronic key secret, wherein the key secret inserted in a transponder, which is read in a known manner by the locking device. It may further be provided that the key secret is a PIN which is entered via a keypad. In addition, the lock may include a fingerprint reader to read the fingerprint of a user. If the key secret is correctly entered, the locking device moves to the release position. The bolt can be preconnected. The locking device holds it in the locked position until the correct key secret is entered again. The lock can have a cashier function. For this purpose, the lock can be opened with a parent key secret. The coin can be removed in the locked back position. With an auxiliary tool, which is inserted into the insertion slot, the two jaws are brought to the appropriate distance by the touring pin can enter into the Tourenausnehmung. By means of the blocking device, the holding jaw can be temporarily tied up in this position. It is envisaged that the trunnion brings the blocking device from the blocking position with fully locked bolt. This can be done by applying the blocking pin. The latter is then moved out of the guide. The rocker can also be fixed in position by means of a screw. For this purpose, the rocker, and in particular formed by the rocker holding jaw form a screw-in, in which a screw can be screwed. With this measure, the scanning can be permanently disabled, so that the lock can be operated without deposit function. In one embodiment of the invention, it is provided that the scanning device with an electrical button or a Switch cooperates. Depending on the operating position of the scanning device, a circuit is closed or opened a circuit. In this way, an electrical signal can be provided which changes its state when a suitable coin is inserted into the insertion slot. This electrical signal can be used to block or release the bolt. For this purpose, an existing anyway in the lock housing solenoid can be used. This is displaced into a release position when the scanning device emits a corresponding electrical signal. In a further development of the invention, it is provided that the coin diameter is scanned directly by a stylus.

The illustrated in the drawings cabinet lock can be attached to a cabinet door 25. It has a housing 1, which can be fixed inside the cabinet door 25 on the inside of the cabinet. The closure has a front panel 26 which can be fastened on the outside of the door. The front panel 26 has a handle 27 with which a crank pin 35 can be pivoted to displace a latch 3 arranged in the housing 1 in a latch displacement direction. The front panel 26 also has a keypad 28 for inputting a numerical code.

In the front panel 26 or in the handle 27 and a transponder reading device may be arranged to read a transponder. The shutter may also be connected to a fingerprint reader.

The housing 1 is made of plastic. The bolt 3 is preferably made of metal. At the bottom of the bolt is a locking slot 30, the two locking stages 31, 34 is formed. In the locking slot 30 engages a locking extension 32 of a locking lever 33 a. The locking lever 33 can be pivoted by means of an electromagnet 29. It can assume a blocking position, in which the locking extension 32 is located in front of the locking stage 31 vorgeschlossenem latch, so that the vorgeschlossene latch of the handle 27 is not zurückschließbar. As an alternative to handling the handle, however, the bolt can also be acted upon in the bolt retraction direction by a compression or tension spring, so that a single displacement of the locking lever 33 from the blocking position into a release position is required to retract the latch 3 from a latch position. To precede the bolt, the crank pin 35, which engages in a recess of the bolt 3, must be rotated. The locking slot 30 forms an additional blocking stage 34. Before this blocking stage 34, the locking extension 32 can lie in the locked-back locking position in order to lock the bolt 3 against preclusion.

On the narrow side of the housing 1 facing upwards in the installed state, there is a coin slot flanked by shaft walls protruding from the narrow side. The edge of the insertion shaft 4 extends in the region of the longitudinal sides of the insertion shaft 4 and forms a bulge 19. This extends almost to the housing narrow side. The bulge 19 is large enough to hold a plug-in slot 4 coin 4 in regions between two fingers.

The insertion shaft 4 is formed by two shaft walls 22, 23, wherein a rear shaft wall 22 extends over the entire wide surface of the insertion shaft 4. The front-side shaft wall 23 extends only over a partial region of the broad side of the insertion shaft 4 and forms a Münzeinsteckbegrenzungssteg 24. At this web 24, which forms the bottom of the insertion shaft 4, the coin 5 is in fully inserted position. In this position, a portion of the coin 5 is located within the bulge 19. The apex of protruding from the housing 1 coin is outside the imaginary Einsteckschachtrandkante.

On the shaft wall 22, a holding jaw 8 is attached. The holding jaw 8 is fastened with screws on the shaft wall 22 such that it can be adjusted in position.

The fixed holding jaw 8 is transverse to Münzeinsteckrichtung a movable holding jaw 7 opposite. Both holding jaws 7, 8 are able to partially enclose the coin 5 in such a way that it is positively secured against being pulled out of the insertion shaft 4. The coin 5 is therefore tied in a peripheral area> 180 °.

The movable holding jaw 7 is associated with a rocker 6. The rocker 6 is designed T-shaped. The two T-legs form a bearing leg 10 and a guide groove 12. The T-bar forms the said movable holding jaw 7.

While the holding jaw 7 extends substantially in the direction parallel to Münzeinsteckrichtung and thus substantially transversely to the bearing leg 10, the bearing leg 10 extends substantially parallel to the displacement direction of the bolt 3. At its the node of the rocker 6 opposite end of the bearing leg 10 by means of a Swivel axis 9 attached to the housing or on the shaft wall 22.

In the node of the rocker 6 is a substantially rectangular rib structure. The ribs 13, 14, 15, 16 and 17 frame up to a tour recess 11 a substantially rectangular space in which a touring pin 18 of the bolt 3 engages. The two ribs 13, 14 flanking the route recess 11 form blocking edges. The rib structure is continued in the direction of displacement of the bolt 3 behind the Tourenausnehmung 11 and forms a guide groove 12 for the touring pin 18th

The touring pin 18 is formed by a rectangular portion of the bolt 3 projecting beyond the back of the bolt 3. At the appropriate point protrudes over the front of the bolt 3 a round pin. The touring pin 18 is located on the opposite side of the locking slot 30 and is associated with an extension of the bolt 3.

Before the opening of the guide groove 12, a blocking member 20 is arranged in the housing 1. This can be relocated with a needle-shaped tool 37, which is inserted into a housing opening 36. With a screw, not shown, it can be fixed in place. The blocking element 20 has a blocking pin 21 which can be inserted into the guide groove 12, so as to fix the rocker 6 in a position in which the Tourenausnehmung 11 lies in the path of movement of the touring pin 18. In this position, the bolt 3 can be moved even when not inserted coin 5. If the blocking element 20 is not blocked in its blocking position by means of a screw or the like, then the towing pin 18 can push the blocking pin 21 out of the guide groove 12 again when the catch 3 is completely closed.

The rocker 6 is spring-loaded by a tension or compression spring, not shown, that when not inserted coin 5 of the touring pin 18 is located in front of the upper locking edge 13. This corresponds to a pivotal position of the rocker 6, in which the movable holding jaw 7 assumes a position closest to the fixed holding jaw 8. In this position, the bolt 3 can not be preconnected because the touring pin 18 can not enter the Tourenausnehmung 11, but runs against the locking edge 14 when the bolt 3 is to be moved.

To be able to close the closure, a coin 5 must first be inserted into the insertion slot 4. The coin 5 is completely inserted into the insertion shaft 4 until it rests against the shaft bottom 24. In this state, there is still a sufficiently large portion of the coin 5 outside of the insertion shaft 4 or in the bulge 19, so that the Coin 5 by attack with two fingers from the insertion slot 4 can be pulled out again.

In the course of insertion of the coin 5 in the insertion slot 4, the two holding jaws 7, 8 are initially spread apart by displacement of the movable holding jaw 7, then slightly approaching again until the coin 5 is held by a form-fitting Teilumgriff. If the coin 5 has the correct diameter, then the tour recess 11 lies in the movement path of the touring pin 18. When the blocking lever 33 is released, the bolt 3 can be locked in by actuating the handle 27. The touring pin 18 dives through the tour recess 11 and enters the flanked by two ribs guide groove 12 a. Once the touring pin 18 is immersed in the guide groove 12, the rocker 6 can not be pivoted. The coin 5 is thus tied in the insertion shaft 4 between the two holding jaws 7, 8. The latch 3 can be prefaced to its end position, in which the locking extension 32 occurs behind the locking step 31, so as to hold the latch 3 in the initial position. The bolt retraction is preferably carried out via a tension spring, not shown, as shown in the DE 198 32 516 A1 is described.

If a coin 5 is inserted into the insertion slot 4 and has a smaller diameter, then the towing pin 18 is in front of the blocking flank 13 when the coin 5 is inserted. The bolt feed is blocked. If a coin 5 with a diameter that is too large is inserted into the insertion shaft 4, then the touring pin 18 is in front of the lower blocking edge 14 when the coin is fully inserted. The bolt 3 can not be displaced even in this position.

The holding jaw 7 has a Schraubeneindreh opening. If a screw is screwed into this screw-in opening, the pivotability of the rocker 6 is blocked. The Schraubeneindreh opening of the holding jaw 7 is preferably aligned with a threaded opening of the shaft wall 23. The threaded opening is positioned such that in the screwed state, the rocker in Fig. 5 illustrated position occupies, in which the touring pin 18 is located in front of the tour recess 11, so that the bolt 3 can be preconnected. The lock can be used with such a permanently fixed rocker 6 as a cabinet lock without pledge function.

In an embodiment not shown, the scanning device 7, 8 has a button or a microswitch. The button can be actuated by the rocker. Preferably, the button is arranged so that it closes a circuit when the rocker their in Fig. 5 shown pivot position assumes that corresponds to the pivotal position with inserted matching coin 5. In all other swivel positions, ie when the coin is not inserted or when the coin is too large or too small, the circuit is not closed. The displacement lock of the bolt 3 is then preferably exerted electromagnetically, for example by the electromagnet 29. This can only relocate the barrier extension 32 in the release position when the circuit of the electrical scanning device is closed. Alternatively, it is also possible that an otherwise closed circuit is opened when properly inserted coin.

In a further embodiment, not shown, it is provided that a switching flag of a button or a switch directly scans the coin, so as to provide an electrical scanning signal.
