Abstract

The lock has a key-operated latch released after insertion of a coin. A shutter holds the latch in back-closed position. The shutter is moved from edges of the coin from a locking position to releasing position. A ratchet lever (2) is deviated from a special key in a holding position holding the shutter. The lever is controlled by forces supplied by closing operation of the latch during closing of the latch.

Description

The invention relates to a lock with a key-actuated latch, wherein the latch closure is released only after inserting at least one matching coin, with the latch in the retracted position holding tumbler, which is displaceable from the edge of the coin against a restoring force from a blocking position to a release position in which the bolt is vorschließbar, and with a locking lever which is pivotable by a special key in a holding the tumbler without coin in the release position holding position.

Such a lock is known in the art from DE 3815716 A1. The lock is designed so that the lock cylinder can be installed on a door after mounting the lock. To install the lock cylinder, you need an auxiliary key. By using the auxiliary key you can turn the lock cylinder on and off again. This allows the user to exchange a lock cylinder quickly and easily. With this lock it is possible to close a locked lock with the help of a special key, to collect the coin and to close the lock again without throwing in a new coin.

From DE 10350951 a lock is known which operates on the deposit and / or cashier principle. The different insertion slots of the coins are arranged so that the one insertion slot in front of the bolt and the other insertion slot runs behind the bolt. The coins lift locking levers with their peripheral edges and make it possible to close the bolt. The locking levers protrude into recesses which are arranged in the latch. When not thrown coins lock the bolt against a closing operation. After closing the bolt, the coins are collected and / or returned as a pledge. The two locking levers are on a common Pivoted pivot point. Both locking levers are located on one side of the bolt. The one locking projection of a locking lever protrudes through a recess of the bolt, and another locking projection of another locking lever protrudes into a further lockout. Through the protruding locking projection a coin on the other side of the bolt can control the locking lever. The locking levers are connected to each other in one embodiment with a pin. To control the locking lever, only one coin of the two possible is required.

The invention has for its object to increase the reliability of a generic lock.

The task is solved by each individual claim alone as well as by any combination of any claim with any other claim. Claim 1 provides, first and foremost, that the locking lever is controlled during the closing of the bolt by a force applied by the closing operation force from the holding position.

A lock known from the documents cited above is preferably designed such that a rotationally driven control flank cooperates with a closing control edge with a counter-control flank of the blocking lever. The control edge is formed by a nut. This is rotated by a lock cylinder. The counter-control flank is formed by an arm of the locking lever. The arm of the locking lever is located in a transverse recess of the nut, the edge of which forms the control edge. The nut is designed in a folding symmetrical way so that it can be used for left / right locking locks. The locking lever can be controlled by an extended back of a special key in a holding position. The extended back of the special key acts on a control extension of the locking lever and is located in the region of the cross section of the nut. The tumbler is in particular of a holding level formed, against which the locking lever is supported in the holding position. The holding step is formed by a projection or an incision. The control edge extends obliquely to a radial through the pivot point of the lock cylinder. The lock cylinder can be removed by a lock cylinder removal key from a receiving housing housing cavity. A lock cylinder, which has been removed with the removal key, can only be re-inserted by means of the appropriate key. The insertion of the lock cylinder with inserted removal key is prevented by sections of the locking lever. The sections of the locking lever protrude into the transverse recess of the nut. The lock cylinder has an associated coupling extension on its side facing away from the key of the insertion side. This can be plugged into a shape-adapted recess of the nut. The coupling extension can be brought only by inserting the lock cylinder in the housing cavity of a suitable key in such a rotational position that it can be inserted through between the locking portions of the locking lever. The edges of two coins are scanned by two tumblers arranged parallel to each other. A latching shoulder of the locking lever cooperates with locking levels each one of the two tumblers together.

The exemplary embodiments are designed essentially as described in DE 10350951 and DE 3815716. The essential difference to the local lock is that the tumbler 1 cooperates with a locking lever 2, which can be brought by a nut 3 into engagement with the tumbler 1 and out of engagement. The tumbler 1 and the nut 3 have the same arrangement to each other, as is the case in the aforementioned writings.

The tumbler 1 has changed from the representations of the above-mentioned writings. It has a holding step 4, which is formed in the first embodiment of an incision and in the second embodiment of a projection. The holding stage 4 is arranged below the tumbler 1 and is located almost vertically above the nut 3.

The tumbler 1 is formed by two tumbler levers 5 and 6. The tumbler levers 5 and 6 are articulated at a common pivot point 7. The tumbler lever 5 forms approximately in its center a hole 8. At the curved free end of the tumbler lever 5, this has on both sides depending on a locking projection 9. The tumbler 6 has at the point at which the tumbler lever 5, the bore 8, a pin 10. This pin 10 protrudes into the bore 8 of the tumbler lever 5 and connects the two tumbler levers 5, 6 with each other. At the curved free end of the tumbler lever 6, this also forms a locking projection 11 to one side.

The locking projections 9, 11 of the tumbler levers 5, 6 of the tumbler 1 protrude into a recess 12 of the bolt 13. The bolt 13 with the recess 12 is shown only schematically. The tumbler 1 is located on one side of the bolt 13. In the entire figures, the tumbler 1 is behind the bolt 13. The locking projection 9 of the lever 5 protrudes into the recess 12 of the bolt 13 into it. The locking projection 11 of the tumbler 6 projects through the recess 12 to the other side of the bolt 13 therethrough. The recess 12 of the bolt 13 forms for the locking projections 9, 11 each have a locking stage 14. Are the two levers 5, 6 coupled to the pin 10, the lock can be actuated by inserting a single coin, with either one of the locking projection 9 or one of the locking projection 11 can be scanned. It can thus be used coins of different sizes. If the two levers 5,6 are not coupled together with the pin 10, two coins must be inserted to operate the lock can.

When not inserted coin, the bolt 13 can not be preconnected. Then enter the locking projection 9 or the locking projection 11 against the respective, associated with him locking stage 14. If the lock with inserted actuated matching coin, so that the locking projections 9 or 11 are supported on the edge of the coin, the locking projections 9, 11 are above their associated locking stages 14 and the locking projection 9 in alignment with the recess 12. When vorschließ the bolt 13, the locking projection 9 thus retract into the recess 12. After vorschließ the bolt 13, the key 27 can be deducted.

The locking lever 2 is arranged below the tumbler 1. This is movably mounted about a pivot point 15. The locking lever 2 forms at the free end on both sides of a latching shoulder 16. The locking lever 2 has on its underside an arcuate arm 17. This forms a counter-control flank 18 on its arc outer surface. On the inside of the bent arm 17, this forms a bearing surface 19. The bearing surface 19 is adapted to a cylinder section. The locking lever 2 has on its underside a control extension 20th

The nut 3 has a cylindrical basic shape. Eccentrically to the pivot point 21 of the nut 3, a coupling pin 22 is arranged. It can be clearly seen from FIGS. 3 and 3a that the nut 3 has a transverse cut 23. The edge 24 of the transverse cut 23 forms the control edge 25. As can be clearly seen with reference to FIG. 3, the section line IIIa-IIIa runs exactly through the center of the nut 3. This section line shows that the nut 3 is configured in a folding symmetry. Thus, the nut 3 can be used for left as well as right-closing locks. Transverse to this section line IIIa - IIIa a recess 26 is arranged.

FIGS. 11 to 13 show the different keys. Figure 11 shows a matching key 27, which allows the closing of the lock only with a matching coin. FIG. 13 shows a special key 28 which has an extended back 29. With the special key 28 it is possible to close the lock without a matching coin. FIG. 12 shows a lock cylinder removal key 30 with which the lock cylinder can be removed from the lock. The cam of the removal key 30 terminates in an actuating portion 31. The back of the removal key 30 is slightly longer than that of the matching key 27 but shorter than that of the special key 28th

FIG. 14 shows a lock cylinder 32, which consists of a lock housing 33 and a core 34. The core 34 protrudes through the housing 33. At one end of the core 34, a coupling extension 35 is arranged. The coupling extension 35 consists of a plastic ring 36 which is arranged around the core 34. At the point where the ring 36 is located, a cutout 37 is incorporated on the housing 33. On the one side of the ring 36, a nose 38 is arranged on the lateral surface. This nose 38 protrudes beyond the outline contour of the housing 33.

Below the cutout 37, a bore 39 is arranged in the housing 33, in which a locking pin 40 is acted upon by a spring 41 in the direction of the ring 36. The bore 39 is open to the end face of the housing 33. The opening has a smaller width than the diameter of the bore 39. At the locking pin 40, a small extension 42 is formed of the same material to operate it by hand. The locking pin 40 engages in a recess of the ring 36 and fixed this rotatably. The core 34 and the ring 36 are axially fixed in the housing 33 by means of a retaining ring 43. At the side facing away from the Schlüsseleinstecköffnung side of the core 34 of this forms a cylinder portion 44. The cylinder portion 44 is followed by a rectangular coupling portion 45. The coupling portion 45 is the recess 26 of the nut 3 adapted to shape. The locking pin 40 cooperates with the actuating portion 31 of the removal key 30. The ring 36 can with the removal key 30 are rotated so far that the nose 38 is pivoted into the cutout 37.

The angle of rotation of the core 34 is limited by cylindrical pins 46, which run in recesses 47 of the core 34 and the ring 36.

• In Figur 1 ist der Riegel 13 zurückgeschlossen und die Sperrvorsprünge 9, 11 liegen bei den Sperrstufen 14. Es steckt ein passender Schlüssel 27 im Schließzylinder 32. Der Kupplungsstift 22 ragt in ein Langloch 48 des Riegels 13 hinein. Das Langloch 48 ist quer zur Längserstreckungsrichtung des Riegels 13 angeordnet. In dieser Drehstellung des Schließzylinders 32 ist es nicht möglich, den passenden Schlüssel 27 herauszuziehen.
• In Figur 2 wurde die Zuhaltung 1 so weit durch eine nicht dargestellte passende Münze verschwenkt, dass die Sperrvorsprünge 9, 11 hinter den Sperrstufen 14 hervortreten. Da die Zuhaltungshebel 5, 6 miteinander gekoppelt sind, ist der Einwurf nur einer passenden Münze nötig, um diesen zu verlagern. Die eine passende Münze greift an den Zuhaltungshebel 5 oder an den Zuhaltungshebel 6 an und verschwenkt die Zuhaltung 1.
• In Figur 3 wurde der Riegel 13 mittels des passenden Schlüssels 27 vorgeschlossen. Der Sperrhebel 2 liegt mit seiner Auflagefläche 19 jeweils in den Figuren 1 bis 3 auf der Mantelfläche des zylindrischen Abschnittes 44 des Kerns 34 auf. Somit ragen der Arm 17 und der Steuerfortsatz 20 in den Quereinschnitt 23 der Nuss 3 hinein. Die Zuhaltung 1 wird wie in der zuvor erwähnten Schrift beispielsweise durch eine Schenkeldrehfeder in Sperrrichtung federbeaufschlagt.

The operation of the embodiments will be explained in more detail below:

• In Figure 1, the latch 13 is closed back and the locking projections 9, 11 are located in the locking stages 14. There is a matching key 27 in the lock cylinder 32. The coupling pin 22 projects into a slot 48 of the bolt 13 into it. The slot 48 is arranged transversely to the longitudinal direction of the bolt 13. In this rotational position of the lock cylinder 32, it is not possible to extract the matching key 27.
• In Figure 2, the tumbler 1 has been pivoted so far by a matching coin, not shown, that the locking projections 9, 11 emerge behind the locking stages 14. Since the tumbler levers 5, 6 are coupled together, the throw of only a matching coin is necessary to relocate it. The one matching coin engages the tumbler lever 5 or the tumbler 6 and pivots the tumbler. 1
• In Figure 3, the bolt 13 was preconnected by means of the matching key 27. The locking lever 2 lies with its bearing surface 19 in each case in the figures 1 to 3 on the lateral surface of the cylindrical portion 44 of the core 34. Thus, the arm 17 and the control extension 20 protrude into the transverse recess 23 of the nut 3. The tumbler 1 is spring-loaded, as in the previously mentioned document, for example, by a leg torsion spring in the reverse direction.

The lock is preferably used on a locker or the like. By inserting a deposit, a user can use the cabinet.

If the cabinet is blocked by the user for a longer period of time than intended, the cabinet can be opened using special key 28. The user pulls off the matching key 27 in the position shown in FIG. In this position, the special key 28 can be inserted into the lock. With the special key 28, the cabinet can be opened again.

In Figure 4, the special key 28 is inserted into the lock cylinder 32. In FIG. 16, it is easy to see that the extended spine 29 of the special key 28 projects into the cylinder section 44 of the core 34. The extended spine 29 of the special key 28 is able to engage the control extension 20. He raises the locking lever 2. In Figure 4, an intermediate position is shown, wherein the extended back 29 of the special key 28 engages the control extension 20 of the locking lever 2 and this pivots in the clockwise direction about the pivot point 15. Along with the return displacement of the bolt 13, the locking shoulder 16 of the locking lever 2 has moved in the direction of the holding stage 4.

In Figure 5, the latch 13 is displaced further towards the housing. Due to the extended back 29 of the special key 28, the locking lever 2 has been pivoted so far that the latching shoulder 16 can engage the support stage 4.

Since the closing of a bolt 13 in a deposit lock the coins fall into a withdrawal shaft, they can be removed by the operator as a fine for a longer closed cabinet. The locking lever 2 now takes over the task of no longer existing coins. The locking lever 2 holds the tumbler 1 in a position shown in Figure 2, so that the latch 13 can be re-connected without having to insert a suitable coin. Thus, after removal of the fine, the cabinet can be closed again.

In Figure 6, the bolt 13 has been prefixed so far that the control edge 25 of the nut 3 abuts against the counter-control edge 18 of the locking lever 2. By further Vorschließ the bolt 13, the control edge 25 moves over the counter control edge 18 and brings the control lever 2 out of engagement with the guard 1. The control edge 25 is an inclined surface. It slides on a curved end portion of the control edge 25, to then slide along an adjoining shoulder along. By a kind of wedge effect, the locking shoulder 16 is displaced out of the holding position. She leaves the holding level 4.

It is essential that the locking lever 2 is held positively in its release position in the pre-closed locking position. It is therefore not possible to manipulate by applying vibrations or the like at the conclusion of the bolt 13 with a matching key 27, the locking lever 2 in the locked position, and then to be able to close the lock without throwing a pledge coin. This is possible only with the special key 28. If it is removed again after removal of the deposit, the cabinet is locked. If, after a long time, the user of the cabinet returns and opens it, he does not receive a deposit back.

In the first embodiment, the holding step 4 was formed by an incision. But it is also possible, as can be seen in Figures 8 to 10, to form the holding stage 4 by a projection. FIGS. 8 to 10 are similar to FIGS. 4 to 6.

In the figure 14, the coupling extension 35 with its nose 38 in engagement with the housing. It would not be possible to remove the lock cylinder 32 from the housing.

In Figure 15, a removal key 30 has been inserted into the lock cylinder 32 and the coupling extension 35 has been pivoted into the release position. The removal key 30 controls with its actuating portion 31 a core cylinder pin against the locking pin 40 and controls it out of the opening of the ring 36 so that it can pivot. Now the nose 38 no longer protrudes beyond the basic contour of the housing 33 of the lock cylinder 32. The lock cylinder 32 can be removed from the lock.

A new lock cylinder 32 can be installed only with a matching key 27. In order to bring the coupling extension 35 into such a rotational position with a suitable key 27 that it can be inserted, one must manually actuate the projection 42 of the locking pin 40 and displace it against the force of the spring 41 while simultaneously twisting the ring 36, that it is as shown in Figure 15. By turning the ring 36 of the matching key 27 is rotated with, since one edge of the recess 47 of the ring 36 in the basic position of the lock cylinder 32 bears against a cylindrical pin 46 and this is connected to the core 34.

The lock cylinder 32 can be inserted only with a matching key 27 in the housing cavity, since the arm 17 and the control extension 20 of the locking lever 32 einliegen in the transverse recess 23 of the nut 3. These portions of the lock lever 2 prevent the lock cylinder 32 from being easily inserted into the housing cavity. By a matching key 27, it is possible to bring the core 34 of the lock cylinder 32 in such a rotational position that it engages under the locking portions of the locking lever 2 and further turning this from the transverse incision 23 nuts 3 out. By turning the matching key 27 and the ring 36 is then brought into engagement with the locking pin 40. The spring 41 displaces the locking pin 40 into the recess of the ring 36 and fixes it against rotation. The lock cylinder 32 is axially fixed by means of the coupling extension 35 in the lock.

All disclosed features are essential to the invention. The disclosure of the associated / attached priority documents (copy of the prior application) is hereby also incorporated in full in the disclosure of the application, also for the purpose of including features of these documents in claims of the present application.
