Description

The invention relates to a lock according to claim 1. Furthermore, the invention relates to a system according to claim 12 and a method according to claim 14.

It is known from the prior art that door locks are used which have a mechanism with a self-locking function. Here, a lock with a lock case is known in which a case is movably received between a protruding from the lock case and a retracted into the lock case position. In the lock case, a slider is received, with which the case can be brought into operative connection via a contact element designed as a roller, and the slider has a contact surface on which the roller can roll along. If the latch is pressed into the lock case, the slider can be moved up a small distance. Furthermore, a lock bolt is received in the lock case, which cooperates with the slide via a slotted guide. When the slider moves in the vertical direction, the lock bolt can be reciprocated between a position retracted into the lock case and a position protruding from the lock case. Furthermore, the lock has an additional case, which cooperates with a stop element, and the stop element is arranged such that the lock bolt is prevented upon a pushing back of the case or the additional case in the lock case from moving into the blocking position.

With the arrangement of the additional trap, a sequence-controlling locking movement is achieved. The lock bolt can not be easily moved out of the lock case. For example, it is not sufficient to push back the case in the lock case, since the slider passes through the co-moving role against the contact surface on the slide and this slightly lifts. In addition, in a renewed movement of the case in the protruding position of the projection of the slider against the disc-shaped executed stop element, which is received on the additional case. However, if only the additional case is pressed into the lock case, the stop element remains in the recess in the projection of the slider, and the slider can not be moved down again, whereby only the extension of the lock bolt could be achieved.

Only when the trap and the additional trap are pressed into the lock case at the same time can the stop element be brought out of the engagement region of the projection in the slide, and if the trap moves again into the protruding position can the slide be moved downwards. As a result of the movement of the slider, the slide guide element runs along in the backdrop, and the lock bolt can be extended from the lock case. The situation of simultaneous actuation of both the latch and the additional latch occurs when the latch is brought into registration with a counter-closing element. A major disadvantage of the cited prior art is that by a manipulative actuation of the case and the additional case it can lead to a false triggering of the castle, in particular the slider moves down, creating a self-locking of the castle arises. For example, such a mechanical-manual manipulation with an open door can cause the lock bolt extends and the door can not be closed self-closing. This is an insecure, as uncontrolled door condition, which is to be avoided.

It is therefore an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to increase the security against manipulation of a lock.

The above object is achieved by a lock with the features of claim 1, a system having the features of claim 12 and a method having the features of claim 14. Further features and details of the invention will become apparent from the respective dependent claims, the description and the Drawings. In this case, features and details that are described in connection with the lock according to the invention apply, of course, also in connection with the system according to the invention and the method according to the invention, and in each case vice versa, so that with respect to the disclosure of the individual invention aspects always reciprocal reference is made or can be.

The object is achieved in particular by a lock for a door, in particular self-locking door lock, with a lock case in which at least one locking element is movably mounted and is movable between a protruding from the lock case position and a retracted position in the lock case. In addition, the invention has an integrated mechanism in the lock case, which has a movable within the lock case guide member which can be brought into a locked position and in a release position. In the locked position, the guide element prevents movement of the Locking element from its outstanding position in the retracted position. In the release position of the guide element a movement of the locking element is made possible in the retracted position.

In the context of the invention it is provided that the lock has a security device which can be brought into a locking position and into a release position. In the locking position, the safety device is in operative connection with the guide element, that movement of the guide element is prevented in the locked position, and that in the release position, the safety device to the guide element is wirkverbindungsfrei, so that movement of the guide member into the locked position is possible. The transfer of the safety device in the locking position or in the release position via a magnetic, in particular a permanent magnetic and / or an electromagnetic, force acting on the safety device. As long as the safety device is in its locked position, the triggering of the self-locking of the lock is not possible. In particular, the safety device positively prevents the guide element from moving into the blocking position. Preferably, the magnetic force is exerted on the outside of the castle. Thus, for example, in a fixed part, such as a door frame, a frame and / or a striking plate, a magnet, in particular a permanent magnet may be arranged, which exerts a sufficient magnetic force, so that the safety device is transferred to the release position.

Characterized in that a magnetic force is required to the safety device from the locking position to the release position Transfer, sufficient manipulation of the blocking element to move the guide member in the locked position. Rather, the manipulative engaging user would have to carry a magnet with him and use it selectively to cause an undesired movement of the guide element in the locked position. Thus, the lock according to the invention is particularly tamper-proof.

The mechanism has, in particular, an auxiliary latch which is movable between a position extended from the lock case and a position retracted into the lock case. The auxiliary latch can act in the mechanism such that in the extended position, the auxiliary latch prevents movement of the guide element from the release position into the locked position and in the retracted position, the auxiliary latch permits movement of the guide element from the release position into the locked position. With the auxiliary latch, a further element may optionally be provided which prevents or permits a movement of the guide element into the blocking position, depending on the position of the auxiliary latch. Thus, the manipulation security is further increased by the auxiliary trap.

In a further possibility it can be provided that the safety device comprises a blocking element, which is spaced in the release position to the guide element and in the locking position in operative connection with the guide element, whereby a movement of the guide element is prevented in the locking position. Advantageously, in the locked position, the blocking element acts positively and / or non-positively on the guide element. The locking position and / or the release position of the safety device can thus correspond to the locking and / or release position of the blocking element. In particular, the guide element may be a recess or a Have projection on which engages the blocking element in the locked position. The recess or projection serves as a first latching area to hold the guide member in the release position until the latch member has reached the retracted position and the safety device has reached the release position. The blocking element can, for. B. movably disposed within a housing of the safety device, in particular linearly movable, be. Advantageously, the blocking element is metallic and / or magnetic, so that the blocking element can be moved into the first latching region and / or out of the first latching region of the guide element via the externally acting force, in particular magnetic force. Particularly preferably, the blocking element is ferrometallic, without being a permanent magnet. As a result, the blocking element can cooperate with the direction of the magnetic force independently of direction. The housing can serve as a guide for the blocking element. In addition, the invention can mitumfassen that within the housing, a spring element is arranged, so that the blocking element is spring-loaded within the mechanism. For example, the spring element can press the blocking element in the direction of the locking position. Advantageously, the blocking element may be formed with a stop to limit the travel of the blocking element.

For example, it is conceivable that the blocking element of the safety device is moved via the magnetic force acting on the safety device and acts in the blocking position on the first latching region of the guide element. When the blocking element leaves the first latching area, with the safety device then reaching its release position, the guiding element is preferably detached from the safety device and can, in particular when the auxiliary latch has its retracted position, move into the blocking position, whereby the self-locking of the lock according to the invention is formed.

In a further possibility it can be provided that the blocking element of the safety device is arranged completely inside the lock case. In particular, the blocking element is arranged completely within the lock case both in the locking position of the safety device and in the release position of the safety device. One advantage is that the manipulation security of the lock according to the invention can be substantially increased, as a manipulative access from the outside is excluded via possible tools. Advantageously, the blocking element is completely isolated from the exterior of the lock, so that manipulation actions to trigger a self-locking are almost impossible.

In a further possibility it can be provided that the safety device can be switched into an active mode and into a passive mode, wherein in the active mode the safety device can be brought into a locking position and into a release position and in the passive mode the safety device is only in the release position is. Switching to the active mode and / or the passive mode can, for. B. via a built-in lock actuator mechanism. Consequently, the lock according to the invention could be factory-equipped with a safety device, whereby the customer has the option to operate the lock optionally with the safety device or without the safety device.

The adjusting mechanism can, for. B. be arranged on the lock body of the castle, the security device is only accessible in a developed lock, without having to open the lock body itself. It is also conceivable that the adjusting mechanism is arranged on the forend of the lock, wherein the safety device is accessible at a built-in lock. For example, the adjusting mechanism can prevent a capture of the locking position in the passive mode by a positive and / or frictional connection with the blocking element. Alternatively and / or additionally, the invention may include that the safety device can be switched electrically and / or electromagnetically into the two mentioned modes. In this case, for example, the safety device may temporarily be in active mode, whereby the self-locking is suppressed. For example, an intake of the locking position in passive mode can be prevented by an electromagnet. By the electromagnet z. B. the force acting on the blocking element magnetic and / or electromagnetic force action are overridden, so that the blocking element remains in the release position. It is also conceivable that an actuating mechanism is controlled by the electromagnet. For example, this adjusting mechanism can prevent a capture of the locking position in the passive mode by a positive and / or frictional connection with the blocking element.

The safety device can be switched on temporarily. One advantage is that this makes it possible in an effective way a day release of a door in which the lock according to the invention can be installed.

It is conceivable that in outstanding position of the locking element, a transfer of the security device is prevented in the release position. Only during a movement of the locking element in the retracted position and / or in the retracted position, the locking element may preferably bring about a transfer of the safety device in the release position. In this case, the blocking element indirectly, z. B. over the guide element, or act directly on the safety device.

For example, the blocking element can act indirectly on the safety device by a stroke of the guide element, so that the safety device can be transferred into the release position by the magnetic force.

Advantageously, in the locking position of the safety device, the blocking element non-positively and / or positively on the guide element, wherein only by a movement of the blocking element in the retracted position, the guide member is raised by the blocking element such that a force and / or positive connection between the blocking element and the suspension element is lifted. The suspension of the force and / or positive connection between the guide element and the blocking element, the blocking element can be brought only in the release position.

The fact that the blocking element in the protruding position prevents a release position of the securing device, is achieved that only when the blocking element reaches the fixed part and is pushed back by the fixed part, a release position of the securing device is made possible. As a result, regardless of the strength of the magnetic force acting on the securing device, a movement of the securing device is only possible when the door is almost or completely closed.

In another possibility, it may be provided that the blocking element is designed as a cross latch or as a roller latch. This has the advantage that the lock according to the invention is versatile, in particular the same lock according to the invention can be inserted into a door which can be opened inwards or outwards. For this purpose, the cross latch on at least two pivotally mounted crosshatch wings. Each cross-falling wing has a case slope on a first side of the trap, while a second side of the trap is formed like a bolt. The second side of the trap may be arranged substantially parallel to a door leaf and / or the lock case, so that preferably when a force acting on the door leaf and / or the lock case, the cross latch is prevented from being transferred to the retracted position. The trailing slopes of the at least two crosshatch wings are arranged opposite one another facing each other. In the release position, the cross latch can be smoothly transferred from both door sides in the retracted position. During the transfer, a crosshatch wing is first pivoted in such a way that the crosshatch wings together form a common trap slope, whereby the cross latch can be transferred to the retracted position. As a result, the door is easy to open on both sides. In the locked position, however, the cross-fall wings are locked so that pivoting of the cross-fall wings is prevented. As a result, prevents at least one of the second case sides a transfer to the retracted position.

Also, the auxiliary trap may be formed like a trap. A protruding from the lock case first part of the auxiliary latch can be pivotally mounted. Additionally or alternatively, the first part may be chamfered so that the auxiliary latch slides on the stationary part. It can be provided that the blocking element in the open and at closed door is in the prominent position. The auxiliary trap can be z. B. with the door open in the extended position and with the door closed in the retracted position.

In a further possibility it can be provided that the mechanism comprises a locking element which is movable into a retracted and extended position, wherein in the extended position the guide element is in the locked position. In this way, advantageously, the safety of a lock according to the invention can be increased, since in addition to the locking element, the locking element in the self-locking of the lock can act simultaneously, in particular both the locking element in the protruding position and the locking element are in the extended position.

It is conceivable that the blocking element prevents a transfer of the guide element into the blocking position in the retracted position, wherein in particular the locking element only extends when the blocking element is in the protruding position or moves into the protruding position. This can prevent that the bolt extends prematurely. In particular, an extension of the bolt is only possible when the door is completely closed.

It is preferably provided that the blocking element remains in the retracted position until the safety device has assumed the locking position and / or the auxiliary latch has moved into the extended position. When the door is opened, the blocking element is forced from the fixed part to the retracted position. While the blocking element is in the retracted position, the blocking element preferably raises the guiding element so far that the safety device can move into the locked position and / or the auxiliary latch in the extended position without a positive and / or frictional connection with the guide element prevents this movement (s) or makes it difficult.

The auxiliary latch can rest in the extended position on a second latching area of the guide element. Advantageously, the auxiliary latch can also be spring-loaded, in particular, the mechanism has a spring element which acts on the auxiliary latch, in such a way that the auxiliary latch is pressed in the extended position. Also, the invention may include applying to the locking member a spring member for urging the locking member into the protruding position. In addition, the invention can mitumFassen that the blocking element has a guide element facing bearing, which can easily lift the guide element when the door is closed or the locking element moves in the retracted position. In this case, the blocking element can engage in a recess of the guide element. The guide element can enable the movement of the locking element from the protruding position to the retracted position, in particular with simultaneous movement of the guide element, in that the bearing comes into contact with a particularly rounded or bevelled edge of the guide element.

The housing of the safety device may be formed of plastic. The forend may be formed with a recess in and / or behind which the housing of the security device is located. As a result, a magnetic force acting on the blocking element. For example, the housing can finish flush with the forend.

Likewise subject of the invention is a system with a lock, which can be arranged or arranged in a door, and with a fixed part, in particular door frame, frame or strike plate. In this case, it is provided that the fixed part has an actuator which acts magnetically on the safety device. Thus, the system according to the invention brings about the same advantages as have been described in detail with reference to the lock according to the invention. In addition, the system may be capable of effecting a reliable self-locking of the lock, with false triggering via manual manipulative operations on the lock or on the door or on the fixed part, in particular on the door frame, excluded. This system can also be used on double-leaf doors.

In a further possibility it can be provided that the actuator is magnetic, in particular has a permanent magnet or is designed as a permanent magnet. A blocking element of the safety device is advantageously ferromagnetic and / or permanent magnetic, so that the safety device can be transferred into the locking position or into the release position via a magnetic and / or electromagnetic force effect. It is particularly advantageous that conventional locks, doors or the fixed part, such as door frames, including with the safety device and the actuator can be retrofitted. The use of a permanent magnet as an actuator also has the advantage that wear is almost impossible, whereby the reliability of the safety device can be permanently increased.

The invention also relates to a method for a self-locking a lock of a door, wherein the lock a Has lock case in which at least one locking element is movably mounted and is movable between a protruding from the lock case position and a retracted position in the lock case position. In addition, according to the invention, the lock has a mechanism integrated in the lock case, which has a movable inside the lock case guide element which can be brought into a locked position and in a release position, wherein in the locked position, the guide element movement of the locking element from the protruding position to the retracted position prevented in the release position allows movement of the locking element in the retracted position.

Further, a safety device is integrated in the lock case, which acts on the mechanism such that movement of the guide element into the locked position only occurs when the safety device detects a closed position of the door via a magnetic, in particular permanent magnetic and / or electromagnetic, force.
Thus, the method according to the invention brings the same advantages as described in detail with reference to the system according to the invention and the lock according to the invention. In addition, the method may be suitable to provide a high degree of manipulation security over the known prior art, since a magnetic force is necessary to trigger the manipulation

In addition, it may be advantageous in the context of the invention that the safety device can be brought about the magnetic force acting from the outside on the lock between a locking position and in a release position, wherein in the locking position, the safety device acts on the guide member and a movement prevents the guide element and in the release position is detached from the guide element and allows movement of the guide element.

a partial view according to FIG. 1 wherein a security device arranged in the lock from a locking position according to FIG. 1 was brought into a release position.

FIG. 1 shows a lock 1, which is arranged in a door 3. The lock 1 has a lock case 11, in which a mechanism 100 is arranged, which will be discussed below. The mechanism has a locking element 10 which is movably mounted within the lock case 11. The blocking element 10 is movable between a protruding from the lock box 11 position 4 and a retracted position 5.

In addition, the mechanism 100 has a guide element 12 which is movable within the lock case 11 and which can be brought into a locking position 13 and into a release position 14. According to FIG. 1 the locking element 10 is in the protruding position 4 and the guide member 12 in the release position 14. The retracted position 5 of the locking element 10 and the locking position 13 of the guide member 12 are in FIG. 1 indicated by dashed lines. In addition, the mechanism 100 has an auxiliary latch 15 which can be moved between a position 6 extended from the lock case 11 and a position 7 retracted into the lock case 11. According to FIG. 1 is the auxiliary latch 15 in the extended position 6, wherein the retracted position 7 is indicated in a dashed line.

Furthermore, the lock 1 according to the invention has a safety device 30 which cooperates with the mechanism 100 as follows: the safety device 30 is located according to FIG FIG. 1 in a locking position 31, which prevents the guide element 12 from its in FIG. 1 engaging release 14 moves into the locking position 13. Below the auxiliary bolt 15, a locking element 40 may additionally be provided, which is in operative connection with the mechanism 100, in particular with the guide element 12. In FIG. 1 takes the locking element 40 a retracted position 42, wherein a corresponding movement of the guide member 12, which will be discussed below, in an extended position 41, the in FIG. 1 shown in dashed lines, can be moved. However, the lock 1 according to the invention can also be realized without the locking element 40.

According to FIG. 1 the safety device 30 is in its locking position 31, wherein a blocking element 33 of the Safety device 30 abuts against a first latching region 16 of the guide element 12. The security device 30 may, for. B. be executed with a housing 35, within this housing 35, the blocking element 33 can be moved linearly. Within the housing 35, a spring 36 is additionally arranged, so that the blocking element 33 is spring loaded within the mechanism 100, and that presses the spring 36 according to the embodiment in FIG. 1 Furthermore, the blocking element 33 is formed with a stop 37 in order to limit the travel of the blocking element 33.

The auxiliary latch 15 is according to FIG. 1 in the extended position 6, wherein the rear portion of the auxiliary latch 15, which acts within the mechanism 100, rests against a second latching portion 23 of the guide member 12. The auxiliary latch 15 is also spring loaded, which means in the specific embodiment according to FIG. 1 For example, the mechanism 100 has a spring element 50 which acts on the auxiliary latch 15 in such a way that the auxiliary latch 15 is pressed in the direction of the extended position 6.

Also on the blocking element 10, a spring element 51 acts to push the blocking element 10 in the protruding position 4. In addition, the blocking element 10 has a guide element 12 facing bearing 52, which can move into a recess 18 when the door 3 is closed, which in FIG. 2 and FIG. 3 is shown.

Starting from an open door, the blocking element 10 is in such a way according to the guide element 12 FIG. 1 positioned so that when retracting the locking element 10 from the protruding position 4 in the retracted position 5, the guide member 12 slightly by a measure X. (S. Fig. 2 ), wherein at the same time the locking element 10, in particular with the bearing 52 enters the indentation 18 of the guide element 12. At the same time, the blocking element 33 releases from the first latching region 16, which in FIG. 2 is shown. In FIG. 1 There is a non-positive contacting of the blocking element 33 on the second latching region 23 of the guide element 12. Through the stroke, the guide element next to the locking position 13 and the release position 14 takes a further position (not shown).

Thus, if now the door 3 is closed and the locking element 10 is moved in the retracted position 5, and the auxiliary latch 15 moves from the extended position 6 in the retracted position 7, wherein in the retracted position 7, the second locking portion 23 of the guide member 12 of the auxiliary latch 15 is left, so that a movement of the guide element 12 in the direction of locking position 13 would be conceivable. However, such a movement of the guide member 12 in the locking position 13 is according to FIG. 2 not yet possible, since both the blocking element 10 in the indentation 18 and the safety device 30 act on the first latching region 16 of the guide element 12.

The lock 1 according to the invention can advantageously be used in a system which has an actuator 34 in a fixed part 8 according to the exemplary embodiment door frame 8, which allows the safety device 30 to leave its locking position 31 only in the closed door position and into the release position 32 according to FIG. 3 moves. Only in the door position according to FIG. 3 a magnetic force acts on the safety device 30 which causes the blocking element 33 to move out of the first latching region 16. According to the embodiment shown, the actuator 34 is a permanent magnet, which on the metallic, ferromagnetic Blocking element 33 can act. Only when the blocking element 33 has moved out of the first latching area 16 and thus the safety device 30 is in the release position 32 and the auxiliary latch 15 is no longer in contact with the second latching area 23 can a self-locking of the lock 1 take place, in which, after the blocking element 10 is moved into the protruding position 4, the guide element 12 can move into the blocking position 13. In the blocking position 13, the guide element 12 is located with its blocking area 17 directly on the blocking element 10, and prevents the blocking element 10 can be moved to the retracted position 5.

In addition, the lock 1 according to the invention has the possibility to arrange a not explicitly shown cylinder in the axis 24 to a manual rotation of the cylinder, in the present Embodiment in the clockwise direction to cause a movement of the guide member 12 in the direction of release position 14.

Upon opening the door, after the guide member 12 has reached the release position 14, the locking member 10 is urged to the retracted position 5. The blocking element 10 engages again with the bearing 52 in the indentation 18 of the guide element 12 a. The engagement remains until the auxiliary latch 15 has reached the extended position 6 and the blocking element 32 has reached the locking position 31. This prevents, on the one hand, that the guide element 12 passes through a spring or by gravity into the release position 14, while the blocking element 10 moves in the protruding position 4. On the other hand, the stroke ensures the secure reaching of the extended position 6 of the auxiliary latch 15 as well as the secure reaching of the locking position 31 of the blocking element 32.

In the present embodiment, the blocking element 10 is a cross-latch. It is particularly advantageous that in the locking position 31 of the safety device 30, the blocking element 33 so non-positively applied to the first latching area 16 that even when manipulated by a permanent magnet 34, the safety device 30 does not leave the locking position 31.

It is also conceivable that the safety device 30 shown in the embodiment can be switched to an active mode and a passive mode, wherein in the active mode, the safety device 30 can be brought into a locking position 31 and into a release position 32. If the security device 30 is in passive mode, it is said that the security device 30 can only assume the release position 32.
