Description

Title: Castle

The invention relates to a lock with a lock case, with a latch and with an additional latch, wherein the latch and the additional latch can each be moved into a position protruding from the lock case and into a position withdrawn into the lock case, according to the preamble of claim 1. The lock has a slide, which can be converted into a release position and in a blocking position. The slider is transferable from the release position to the locked position when a movement occurs in which the latch and the additional latch are first transferred from the protruding positions to the retracted positions and then the latch is transferred to the protruding position while the additional latch remains in the retracted position.

DE 60 2004 007 517 T2 discloses a generic lock, in which a case and an additional trap must first be withdrawn into a lock case and then the trap must be extended again to allow movement of the slider from the release position to the locked position , By contrast, the slide does not move into the locked position, if only the case or the additional trap are withdrawn. For this purpose, a stop element is provided which prevents the slide from moving into the blocking position. The movement of the slider into the locking position can be released by a tilting movement of the stop element when both the latch and the additional latch are retracted into the lock case. The disadvantage of this is on the one hand, that a movement of the slider is prevented in the blocking position only by the stop element. If the stop element breaks, the slider undesirably moves into the blocking position, even if

CONFIRMATION COPY the trap and / or the additional trap are in the protruding position. On the other hand, the tilting movement of the stopper element can tilt, so that the stopper element does not release the movement of the slider even when the case and the additional catch are retracted.

It is therefore the object of the present invention to provide a lock that can be operated particularly reliably.

To solve this problem, a lock with the features of claim 1 is proposed. In the dependent claims preferred developments are given.

According to the invention it is provided that the slide is held in the release position at at least a first and a second holding position of the slider, which are spaced apart. In this case, spaced means, in particular, that a stop at the first and at the second holding position can be reached and released independently of one another. The fact that the slider is held in at least two holding positions in the release position, even if an undesirable transfer of the slider is prevented in the locked position when a stop at one of the holding positions z. B. deleted because of a break. The slide can be held positively and / or non-positively at the holding positions. In particular, the slide is held in a form-fitting manner at the first and / or second holding position. In this case, the stop at the first stop position corresponds to a first positive connection and / or the stop at the second stop position corresponds to a second positive connection.

In the release position of the slide, it is possible to close a door leaf in which the lock is arranged. If the door leaf is closed, the slider in the blocking position prevents an opening of the door leaf. Due to the transition from the release position into the blocking position, the slider can cause a locking of the door leaf. advantageously, the slider is in the release position with the door leaf open and in the blocking position with the door leaf closed.

It can be provided that a latch can be moved from an unlocking position, in which the latch is retracted in the lock case, into a locking position, in which the latch protrudes from the lock case, by a movement of the slide. In order to lock the door when the door leaf is closed, the lock may have a latch, which can engage in the locking position in a counter-closing element, which is used for example in a door frame or in a passive leaf. In the locked position, the latch locks the door leaf. In the unlocked position, the door leaf is unlocked. In particular, the latch is transferred from the unlocked position into the locking position, in that the slider moves from the release position into the blocking position. The slider can in particular move the bolt by a positive guide. For example, the slider may have a backdrop in which a link guide element of the bolt is guided. The gate can be designed so that a vertical movement of the slider causes a horizontal movement of the bolt.

Additionally or alternatively to a locking by the bolt can be provided that the slider prevents in the locked position a transfer of the trap in the retracted position. Thus, in the locked position, the slider can prevent the latch and / or the latch from retracting into the lock case and / or the slider can cause the lock position of the latch to move to the locked position. The slider can allow the case to be retracted in the release position. Additionally or alternatively, the slide can cause the unlocking position of the bolt by moving into the release position. In particular, the slider can only be transferred from the release position to the blocking position when the additional latch and the latch are retracted together into the lock case and then the latch extends again. Preferably, during the extension of the case, the additional case remains withdrawn in the lock case. These movements may be provided in particular during a closing operation of the door leaf. Preferably, the slider remains in the release position when either only the case or only the additional case are withdrawn into the lock case.

In the lock according to the invention, in particular, the slide is biased by a slide spring in the direction of the blocking position. The trap can be transferred from the retracted position to the protruding position by a latch spring. The additional trap can be moved by an additional fall spring in the protruding position of the additional trap. The direction of movement of the slider can be predetermined by a guide. For this purpose, the slider may have a guide groove in which engages a guide element of the lock case. It is conceivable that when the latch is transferred from the protruding position of the latch to the backward position of the latch, the stop at the first holding position can be canceled. Additionally or alternatively, in a transfer of the additional case of the protruding position of the additional latch in the retracted position of the additional case of the stop at the second holding position can be canceled. Thus, it is conceivable that both the case can cause a hold and the additional case another stop or solve. As a result, the first and the second holding position are independent of each other. If only the case is withdrawn into the lock case, then the slider is held in the release position by stopping at the second holding position. If only the additional case is withdrawn into the lock case, the slider is held in the release position by the stop at the first holding position. Here, the first and the second holding position can each be directly on the slide.

Advantageously, it can be provided that the stop at the first and / or the second holding position blocks the movement of the slide in a direction of movement in which the slide moves from the release position into the blocking position. At least one of the two holders, in particular both holders, can be designed such that the movement of the slider from the release position to the locked position is prevented. For this purpose, during the stop at the first and / or the second holding position, the slide can abut against an element which is arranged in the blocking position in the direction of movement of the slide and thus blocks the direction of movement. In this way, a simple and safe construction of the lock can be ensured, in which, for example, tilting is prevented.

It is conceivable that the stop at the first and / or at the second holding position can be canceled by itself without the slider moving. This allows the slider to be protected from wear. If only one stop is lifted, at least one further hold of the slide remains. As a result, the slider remains in the release position. In order to protect the slider from wear in such a case, the stop at the first holding position, in particular by a retraction of the case in the lock case, can be canceled without the slider moves. Also or alternatively, in particular by a retraction of the additional latch in the lock case, the stop at the second holding position can be canceled without the slider moving.

In particular, the lock can be configured such that during the movement sequence, the slider is moved in one direction only. During a movement of the slider from the release position in the Locking position, it is therefore not necessary to move the slider back and forth. As a result, the lock according to the invention can be made compact. In particular, it can be provided that the slide performs only a linear movement, in particular a vertical downward movement, during the movement sequence. A stroke movement of the slider is eliminated.

The lock may have a first actuating element, in particular a lever. The first actuating element may be arranged in the lock to enter the stop at the first holding position with the slider. The first actuator can be brought into operative connection with the trap. In particular, the first actuating element can be actuated by the latch in order to release the first positive connection with the slide. It can be provided that the first actuating element is spring-loaded in the direction of the slide by a spring element. In this way, the first actuating element can enter the stop at the first holding position with the slider by the force of the spring element.

In particular, the first actuating element can be designed as a two-armed lever. Here, a first arm of the lever can engage in a recess of the slider. The recess thus serves as the first stop position of the slider. A second arm of the lever can be actuated by the latch. It is provided in particular that the second arm of the lever can be brought into operative connection with a contact element of the latch. The contact element can be designed, for example, as a latch shaft which has a roller or a cam. The contact element may be mechanically fixed in the case, so that moves in a movement of the case, the contact element accordingly. It is conceivable that the additional latch has a locking element that causes the stop at the second holding position. In particular, the locking element may be formed monolithically with the additional trap. The lock may have a second actuating element, in particular a pivot lever, which holds the slider at the second holding position. In this case, it is in particular conceivable that the second actuating element directly holds the slide, while the second actuating element itself is prevented from moving in a direction of movement which corresponds to the transfer of the slide from the release position into the blocking position. To determine the second actuating element, in particular the locking element can be provided. Thus, it is conceivable that the second actuating element is held immovable by the locking element when the additional latch is in the protruding position.

It can be provided that the second actuating element has a cam which engages in the slide. Here, the cam of the detected, second actuating element can hold the slider at the second holding position. In particular, the cam can be guided in a slot of the slider. Here, the slot is used as the second holding position of the slider. Is the second actuator not immobile held, but z. B. the locking member releases the second actuating element, the second actuating element can be moved by the slider in particular in a transfer of the slider from the release position to the blocking position. In this case, a movement of the second actuating element by the slide can be effected by a forced operation. The movement of the second actuating element may be a pivoting movement.

It is conceivable that the bolt is secured in the unlocked position. This means that in addition to the slide, the bolt in the locked position holds in the locked position, a further element is provided which holds the latch positively and / or non-positively in the unlocked position. In particular, the bolt is held in the unlocked position at least twice positive and / or non-positive. By securing the bolt in the unlocked position a game of the bolt in the unlocked position can be effectively reduced. As a result, a grinding of the bolt can be avoided. In particular, the second actuating element may be the further element that secures the latch. In this case, the second actuating element can hold the latch in the unlocked position positively and / or non-positively.

In particular, it is provided that, when the second actuating element is detected by the locking element, the second actuating element holds the bolt at the same time, in particular form-fitting manner. In order to hold the bolt positively, the second actuating element may have a projection which engages in a recess of the bolt.

In particular, it can be provided that the second actuating element holds the latch, as long as the slide is held by at least one stop in the release position. Here, the held slide, the second actuating element, in particular a form-fitting, hold, so that the second actuating element can secure the bolt.

In particular, the second actuating element can be designed as a two-armed pivoting lever. A first arm of the pivoting lever can be brought into operative connection with the locking element. As a result, the pivot lever can be determined. A second arm of the pivoting lever can be brought into operative connection with the latch. For this purpose, the second arm may have the projection.

If the trap and the additional trap are in the retracted position, then in particular the hold on the first and on the second shark can be repealed. Thus, the slider can move in the direction of the blocking position. At a complete transfer to the locked position of the slider can be prevented by the case. The case is in the retracted position, the case, in particular the contact element of the case, block a movement of the slider in the blocking position. As long as the case is retracted into the lock case, thus, the slider will assume an intermediate position in which the slider rests against the latch. If the latch moves into the protruding position, the slide can extend to the blocking position. The contact element can thus have a dual function. On the one hand, the contact element can actuate the first actuating element and, on the other hand, the contact element can prevent the slide from extending into the blocking position. In the intermediate position, in particular, the contact element can engage in an undercut of the slider. In particular, the intermediate position may lie between the release position and the blocking position.

With further advantage, an electronic actuator unit can be provided, which can come into operative connection with the slide for moving the slider. The actuator unit may be connected to a center in a building, for example via a cable and / or via a radio link, thus the slider can be moved by remote control, for example, to transfer the latch by remote control in the unlocked position. Additionally or alternatively, the slide can be converted by the operation of a door handle or a lock cylinder back into the release position.

Further advantages, features and details of the invention will become apparent from the following description in which a possible embodiment of the invention is described in detail with reference to the drawings. In the claims and in the Spelling mentioned features each individually by itself or in any combination essential to the invention. Show it:

Technical features with the same function and mode of operation are provided in the figures 1 to 4 with the same reference numerals.

FIGS. 1 to 3 show a lock 1 according to the invention with a lock case 10 which can be inserted into a door leaf. Figures 1 to 3 differ in the state in which the lock 1 according to the invention is shown. Thus, in the figure 1, the lock 1 according to the invention is shown as the lock 1 is usually designed with an open door leaf. In contrast, FIG. 3 shows a state of the lock 1 with a closed door leaf. In Figure 2, a transition state is shown, in which the lock is 1, while the door leaf is closed.

In Figure 1 is a case 11 in a protruding from the lock case 10 position 55. Also, there is an additional trap 15 in Figure 1 in a protruding from the lock case 10 position 57. The case 11 can against the force of a latch spring 13 in a back - pulled position 56 of the latch 11 are pressed. Likewise, the additional latch 15 can be pressed against the force of an additional latch spring 17 from the protruding position 57 of the additional latch 15 in a retracted position 58 of the additional latch 15. The simultaneous actuation of both the latch 11 and the additional latch 15 then occurs while the door leaf is closed, as shown in FIG. During the closing process, the latch 11 and the additional latch 15 can be pressed into the lock case 10, wherein the lock passes against a non-illustrated counter-closing element, which is used for example in a door frame or a fixed leaf. If the door leaf is completely closed, the latch 11 is again transferred to the protruding position 55 of the latch 11 and can engage in a corresponding opening in the counter-closing element. The trap 11 is designed as a cross latch. For the additional latch 15 there is no corresponding opening in the counter-closing element, so that when the door leaf is closed, the additional latch 15 remains in the retracted position 58, as shown in FIG.

The lock 1 according to the invention has a latch 30 which, when the door leaf is opened, is retracted in the lock case 10 and thus is in an unlocking position 53, as shown in FIG. If, however, the door leaf is closed, then the latch 30 is in a locking position 54, in which the latch 30 protrudes from the lock case 10, as shown in FIG. In the locking position 54, the bolt 30 engages in a corresponding opening of the counter-closing element.

The latch 30 is moved from the unlocking position 53 into the locking position 54 by the movement of a slider 20. In this case, the slide 20 moves from a release position 50 into a blocking position 51 according to a direction of movement 44 by the force of a slide spring 21. The slider 20 is moved by a lock case 10 in the lock case. arranged guide element 23 is guided, which engages in a guide groove 22 of the slider 20. Also, the latch 30 is transferred from the locking position 54 in the unlocked position 53, when the slider 20 moves from the blocking position 51 in the release position 50. In the blocking position 51, the slider 20 also prevents a transfer of the latch 11 from the projecting position 55 to the retracted position 56, as shown in FIG.

In order to prevent that at a random impressions of the case 11 or the additional latch 15, the slider 20 is already transferred from the release position 50 in the blocking position 51 and thus the latch of the unlocked position 53 in the locking position 54, the slider is according to the invention at two spaced holding positions 24, 27 held in the release position 50. In FIGS. 1 to 3, two positive connections of the slide 20 are provided.

The two form-fitting are independent and spaced from each other. A first positive connection is provided between a first actuating element 33 and the slider 20. The first actuating element 33 is in this case designed as a two-armed lever 33, which is mounted pivotably about an axis 43. The lever 33 has a first arm 34, which can engage in a recess 27 of the slider 20 and so brings about the first positive connection with the slider 20. The recess 27 thus serves as a first stop position. The first arm 34 and the recess 27 have inclined surfaces for the first positive connection. A second arm 35 of the lever 33 is formed longer than the first arm 34. The second arm 35 can be pivoted by the latch 11. For this purpose, the case 11 has a contact element 12. The contact element 12 has a latch shaft 46 and a rotatable roller 47. The contact element 12 is rigidly arranged in the case 11 and is translationally moved with a change between the protruding position 55 and the retracted position 56 of the case 11. The Trap 11 also has a pivoting limit 14 which limits a pivotal movement of the lever 33. In the figure 1, the second arm 35 of the lever 33 abuts the pivot boundary 14. If, in FIG. 1, the latch 11 is moved from the protruding position 55 into the retracted position 56, as shown in FIG. 2, the lever 33 is counteracted by the contact element 12, in particular by the latch shaft 46, against the force of a spring element 36 pivoted so that the first arm 34 passes out of the recess 27 and thus the first positive fit is canceled with the slider 20. The second arm 35 of the lever 33 can slide on a chamfer of the latch shaft 46, as shown in Figure 2.

So that the slider 20, if only the case 11 is pressed, remains in the release position 50, a second positive connection, which is caused by the additional latch 15, is provided. For the second positive connection, the lock 1 according to the invention has a second actuating element 37. The second actuating element 37 is designed as a pivot lever 37, which is pivotable about a pivot axis 42. The pivot lever 37 has a cam 40 which engages in a slot 24 of the slider 20. If the pivot lever 37 immovably detected, so the cam 40 is a fixed element. Thus, the second positive connection is formed between the cam 40 and the slot 24 of the slider 20. Here, the slot 24 serves as a second holding position of the slider 20th

In Figure 1, the pivot lever 37 is detected by a locking element 16, so that the pivot lever 37 can not rotate clockwise. Here, a first arm 38 of the pivot lever 37 rests on the locking element 16. The locking element 16 is in this case a monolithic part of the additional case 15. If the additional latch 15 is transferred from the protruding position 57 to the retracted position 58, the locking element 16 gives a pivoting movement of the pivot lever 37 clockwise as shown in Figures 2 and 3. As a result, the cam 40 has become movable, so that the second positive connection between the slider 20 and the second actuating element 37 is canceled.

If only the case is withdrawn into the lock case 10, but not the additional latch 15, then only the first positive locking is released and the slider 20 remains in the release position 50. If only the additional latch 15 is pressed in, only the second positive lock is released. The slider 20 remains in the release position 50, since the slider 20 is held by the first positive engagement in the release position 50. Advantageously, not the slider 20, but the lever 33 must be moved to cancel the first positive fit. The cancellation of the second positive connection takes place by a movement of the additional latch 15 with the locking element 16, without the slide 20 has to move. As a result, wear of the slider can be kept low.

By the first positive locking, which can be solved by the case 11, and the second positive locking, which can be solved by the additional latch 15, two independent form-fitting in the lock according to the invention are provided. Can one of the form-fitting be no longer entered, z. B. because the first arm 34 of the lever 33 or the cam 40 of the pivot lever 37 is broken off, so the slider 20 is further held in the release position 50 during the opening of the door leaf. Furthermore, the first and second form-locking are simply designed so that they can be solved and dealt with in a simple and less error-prone manner. The cam 40 and the first arm 34 of the lever 33 also form a blockage in the direction of movement 44, so that tilting is prevented. As has been stated, depressing the latch 11 or the auxiliary latch 15 does not result in movement of the slider 20 from the release position 50. However, if the latch 11 and the latch 15 are pressed together during the closing movement of the door panel, both the first and the second latch will be depressed the second positive locking released, so that the slider 20 can move in the direction of the blocking position 51. In this case, the slider 20 first reaches an intermediate position 52, which is shown in FIG. In the intermediate position 52, the contact element 12 is located in an undercut 28 of the slider 20, the slider 20 with a surface 29 of the undercut 28 on the roller 47 of the contact element 12 is positively applied. The contact element 12 thus prevents the slider 20 continues to pass through the slider spring 21 in the blocking position 51. In the intermediate position 52 of the slider 20, the lever 33 rests against the slider 20 above the recess 27 with the force of the spring element 37 and can not swing back into the recess 27. The intermediate position 52 is located between the release position 50 and the blocking position 51, so that the slider 20 only performs a linear vertical downward movement from the release position 50 via the intermediate position 52 into the blocking position 51. A lifting movement of the slider 20 is omitted.

If the door leaf is closed and there is a corresponding opening with respect to the latch 11, the latch 11 projects out of the lock case 10 by the force of the latch spring 13. As a result, the contact element 12 releases the slider 20 in order to extend into the blocking position 51.

The slider 20 and the bolt 30 are operatively connected to each other via a gate 25 of the slider 20 and a gate guide element 32 arranged on the bolt 30. During the movement of the slider from the release position 50 into the intermediate position 52, the bolt is not yet moved, since the slide guide element 32 is inserted in a groove. Lissenfortsatz 26 of the backdrop 25 is located. So that the bolt 30 is not moved, the sliding extension 26 is in the direction of movement 44 of the slider 20, that is, vertically formed. However, during a movement of the slider from the intermediate position 52 into the blocking position 51, the vertical downward movement of the slide 20 is converted into a horizontal movement of the bolt 30 by the oblique configuration of the slide 25, which thus extends out of the lock case 10. In this case, the slider 20 and the bolt 30 close a right angle.

The bolt 30 is held in Figure 1 in addition to the gate 25 by the pivot lever 37 positively in the unlocked position 53. For this purpose, a projection 41 of a second arm 39 of the pivot lever 37 engages in a recess 31 of the bolt 30 a. As long as the slider 20 is held by the first and / or second positive locking in the release position 50, prevents the slider 20 via the formed by the cam 40 and the slot 24 operative connection with the pivot lever 37, that the projection 41 out of engagement with the recess 31st arrives. After the locking element 16 has released the pivoting movement of the pivoting lever 37 and the positive connections of the slider 20 are released, the pivot lever 37 is pivoted clockwise during the movement of the slider 20 from the release position 50 into the locking position 51. In this case, the projection 41 moves out of the indentation 31 and releases the latch 30. By the pivot lever 37 secures the bolt 30, a game and thus wear of the bolt 30 can be reduced.

In order to open the lock again, a rotation of the follower 18 can be caused by a door handle, which is not shown in detail, which can be received in a follower nut 18, in order to move the slider 20 against the slide spring 21 again. The door handle can be arranged, for example, only room inside, and that Lock 1 can not be opened from a room outside. Furthermore, a driver 19 of the slide 20 can be activated via a lock cylinder, which can be used in a lock cylinder receptacle 45, in order to move the slide 20 against the slide spring 21. Also, the slider 20 can be transferred to the release position 50 via an electrical actuator unit again. With the movement of the slider 20 in the release position 50, the slide guide element 32 and the pivot lever 37 and again in the positions shown in Figure 1, be transferred and the latch 30 is withdrawn into the lock case 10. The slider 20 is also held by the manual or electrical operation in the release position 50 until the lever 33 can engage in the recess 27.
