Description

DESCRIPTION

Lock with a latch and an additional latch as operating safe

The present invention relates to a lock for a door with a lock box, with at least two latch elements, specifically a latch and another additional latch, and with a locking element, wherein the latch is mobilely housed. in the lock box between an outstanding position of the lock box and a retracted position within the lock box, wherein the additional latch is mobilely housed in the lock box between an outstanding position of the lock box and a retracted position inside the lock box, where the blocking element can be brought from a first position to a second position, where in the first position of the blocking element a locking state of the lock is prevented, which serves to the interlocking of the door, where the blocking element can only be taken from the first position to the second position if previously developed a movement process, wherein the movement process comprises that the latch is brought at least partially from the protruding position to the retracted position and the additional latch is carried at least partially from the protruding position to the retracted position, in accordance with the general concept of claim 1.

State of the art

From EP 2673434 A1 a lock is known that represents gender. Because the locking element can only be moved to the second position if a movement process is previously developed, in which both the latch moves at least partially to the retracted position as well as the additional latch moves at least partially to the retracted position, an operation insurance is obtained, in which an interlocking of the door is achieved, if the movement process has previously been developed. In this regard, the interlocking of the door is produced by means of a lock bolt that extends to a locked position. This prevents an accidental extension of the lock bolt with the door open just by pushing back on the latch or just by pushing back the additional latch. In order to achieve the safety of operation, the locking element makes a reciprocating movement between the first position and the second position by means of a latch cam of the additional latch and by a spring element.

In DE 102008014369 A1 a lock is disclosed, in which a movement of a bolt depends on the electric charge applied to an electromagnet.

The objective of the present invention is to provide an alternative embodiment for a lock with a latch and an additional latch with a safety catch.

This objective is achieved on the basis of a lock according to the general concept of claim 1, in combination with the distinctive features. Advantageous developments of the present invention are indicated in the dependent claims.

Exhibition of the invention

The present invention includes the technical principle that the blocking element moves to at least one of the positions of the blocking element by effect of at least one magnetic force acting inside the lock box, where the magnetic force acts between the locking element and one of the latch elements. According to the present invention, through a movement of the blocking element by effect of a magnetic force, a door interlock can be achieved and / or prevented. In this regard, the magnetic force acts inside the lock case. That is, in particular, this means that the magnet or the magnetic element, by whose force the blocking element moves, is disposed within the lock case. Because of this, it is not necessary to provide a magnet or magnetic element on the outside of the lock case. Therefore, easy mounting of the lock according to the present invention is possible. In the magnet or the magnetic element, by whose magnetic force the blocking element moves, it is preferably a permanent magnet. Therefore, the lock can be designed, among other things, purely mechanically.

Preferably, the magnetic force moves the blocking element from the first to the second position. Alternatively, the magnetic force can also move the locking element from the second position to the first position. It may also be that a magnetic force is provided to move the blocking element to the second position and another magnetic force to move the blocking element to the first position.

The lock can cooperate with an antagonist locking element. The antagonist closing element can be used to push the latch and / or the additional latch back into the lock case during a door closing process. The antagonist closing element may have an opening, in which the latch engages when the door is closed. The antagonist closure element can also additionally have an opening for a lock bolt. The antagonist closure element can be made, for example, as a closure plate.

In the first position of the blocking element, the blocking element prevents a door enervation. For this, the locking element prevents the lock from entering an interlocking state, which serves to lock the door. If the locking element is in the first position, then no element acting as a bolt has been extended in such a way out of the lock case that the element may cause the locking state. In the interlocking state, the element that acts as a bolt protrudes from the lock case.

In the second position of the blocking element, the blocking element allows a door interlock. For this, the locking element allows the lock to enter a locked state. In this regard, an element that acts as a bolt can protrude or extend out of the lock case. Therefore, a door interlock can be achieved in the second position of the locking element with the door closed. The element that acts as a bolt can be designed as a lock bolt. The lock bolt in the first position of the locking element can be found in an open position. In the open position, the lock bolt is retracted into the lock case. The lock bolt in the second position of the blocking element may be in a blocking position or move to the blocking position. In the locked position, the lock bolt protrudes out of the lock case.

Additionally or alternatively, the latch can also be designed as a cross latch. The cross latch has a body part and at least two pivoting head pieces therein. In the first position of the locking element, the head pieces of the cross latch can pivot, such that the cross latch does not act as a bolt. In the second position of the locking element, the locking element allows the cross latch to be locked such that the head pieces cannot move and the cross latch acts as a bolt. Therefore, the element that acts as a bolt can be the cross latch.

Additionally or alternatively, the latch may have a bolt-like section that acts as a bolt. In the first position, the locking element prevents the bolt-like section from extending out of the lock case. In the second position, the locking element allows the bolt-like section to extend out of the lock case.

The lock can be designed in a self-locking manner. Therefore, the door leaf can move without human intervention by means of a movement of the door leaf to occupy its position in the door frame and put there in an interlocking state. In particular, no actuation of a door handle, panic bar or door knob or the rotation of a key is required for this.

In the process of movement it can only be provided that the latch moves in the direction towards the retracted position and / or that the additional latch moves in the direction towards the retracted position. In a particularly safe variant of the movement process, it may also be that the latch moves to the retracted position and / or that the additional latch moves to the retracted position. The movement of the latch and the additional latch preferably overlap at least chronologically. In particular, for at least one moment, it is necessary that both the latch move to the retracted position and also that the additional latch move to the retracted position, so that the locking element can move to the second position.

The movement process can also comprise that the latch after moving to the retracted position moves again to the outstanding position. Therefore, the door can only be interlocked if first the latch and the additional latch move back and then the latch extends outward again. Alternatively, the locking element can be moved to the position already after the latch and the additional latch have been retracted, but the locking state of the lock will only be established, if the latch moves at least partially back to the protruding position. For example, the retracted latch can prevent the locking state of the lock.

The lock may comprise a slide. The slide can be mobile between at least a first position and a second position. In the second position of the slide, a door interlock can be made. The locking element in the first position can prevent a movement of the slide to the position. The locking element in the second position may allow a movement of the slide to the second position. In the second position of the slide, for example, the cross latch can be locked in such a way that the head pieces are immobile and the cross latch acts as a bolt. The slide can move the lock bolt to the locked position. Preferably, the slide moves the lock bolt to the locked position, while the slide moves from the first to the second position. For this, the slide can be connected, for example, to the lock bolt through a slide guide. The slide guide can be made with a collar integrated in the slide and a slide guide element arranged in the lock bolt.

Preferably, the locking element is disposed within the lock case. In this regard, the locking element can be arranged entirely within the lock case. Because the magnetic force Inside the lock case acts on the locking element, the lock case can be made of ferromagnetic material. This allows a simple construction. The lock can be designed in such a way that starting from the blocking element in the direction, in which in the assembled state of the lock the antagonist closing element is connected, the lock housing is made of a ferromagnetic material.

It is conceivable that the blocking element has at least one magnetic element, in particular a permanent magnet. The magnetic element can at least contribute to the magnetic force. In this way, the magnetic element of the blocking element can cooperate with a ferromagnetic material inside the lock case or with a magnet arranged inside the lock case. The magnetic element is preferably oriented in the direction of movement of the blocking element from the first to the second position. In this way, the north pole or south pole can point in the direction of movement. The magnetic element can be made as a bar magnet.

The latch and / or the additional latch may have a body part. The body part is in particular in both the outstanding position and also in the retracted position within the lock case. The latch and / or the additional latch may have at least one head piece. The head piece in the protruding position of the latch or in the protruding position of the additional latch extends out of the lock case. The body part and the head piece may be rigidly made of one another, in particular in one piece. Alternatively, it is also possible that the latch and / or the additional latch is present in at least one pivoting head piece in the body piece. Preferably, the additional latch has a pivoting head piece. The latch may, as described, be made as a cross latch.

In accordance with the present invention, it is provided that the magnetic force acts between the locking element and one of the latch elements. In the latch element it may be in particular the additional latch. Preferably, the magnetic force acts between the locking element and the body part of the latch element, in particular of the additional latch.

The latch element that interacts with the locking element by means of the magnetic force can be made of a ferromagnetic material.

Preferably, the magnetic force that moves the locking element to the second position is a magnetic attraction force. That is to say that the blocking element moves to the second position due to a force of magnetic attraction. The magnetic attraction force acts preferably between the additional latch and the locking element. For this, the additional latch can be made of a ferromagnetic material or have a magnet.

It is possible that a movement of the blocking element from the second position to the first position is caused by a magnetic force, in particular by a magnetic repulsion force. Preferably, the magnetic force acts to move the blocking element to the first position between one of the latch elements, in particular the additional latch, and the blocking element. It is possible that the blocking element moves both to the first position and also to the second position by the effect of magnetic forces. Particularly preferably, the magnetic force acts to move the blocking element to the second position between the blocking element and the latch element which also in relation to the additional magnetic force to move the blocking element to the first position interacts with The blocking element.

Additionally or alternatively, a force accumulator, preferably a spring, particularly preferably a pressure spring, can be provided to move the locking element to the first position. The force accumulator is provided in particular between the immovable support surface of the lock and the locking element. The force accumulator can rest on the support surface of the lock. The force accumulator can charge the locking element in the direction towards the first position. If the locking element moves to the second position, then the force accumulator is charged. In particular, the spring is tensioned during the movement of the locking element to the second position. In the case of a pressure spring, the pressure spring is compressed during the movement of the locking element to the second position. The force accumulator may be guided by a spring guide. The spring guide can be made immobile. The blocking element may comprise an additional support surface, with which the force accumulator comes into contact.

It is conceivable that the at least one magnetic force, acting on the blocking element, is modified as a function of a movement of the latch element, in particular of the additional latch. The magnetic force acting between the locking element and the latch element, in particular the additional latch, can be modified with a movement of the latch element, in particular of the additional latch. Therefore, a movement of the latch element can be detected by the variation of the magnetic force. For example, the magnetic force acting on the blocking element in the protruding position of the additional latch may be greater or less than the magnetic force acting on the blocking element in the retracted position of the additional latch. In particular, the magnetic force acting on the blocking element, and moving the blocking element to the second position, in the protruding position of the additional latch may be less than the magnetic force acting on the locking element in the retracted position of the additional latch. For example, the additional latch can be made of ferromagnetic material only by sections.

It is conceivable that the latch element, on which the magnetic force acts in relation to the blocking element, has at least one magnet, in particular a permanent magnet. The latch element may in particular be the additional latch. The magnet can be provided alternatively or additionally to the magnetic element in the lock. Thus, for example, the blocking element may be made of ferromagnetic material and the latch element may have the magnet. Alternatively, the locking element may comprise the magnetic element and the latch element, in particular the additional latch, may comprise the magnet. It is conceivable, in particular, that due to the magnet of the latch element, which acts on the locking element, the magnetic force is modified as a function of a movement of the latch element. If the magnetic force acts to move the blocking element to the second position, then the magnet is preferably in the retracted position of the additional latch, at least partially in the direction of movement of the blocking element from the first to the second position. . If the magnetic force acts to move the blocking element to the first position, then the magnet is preferably in the outstanding position of the additional latch, at least partially in the opposite direction to the movement of the blocking element from the second to The first position.

The latch element, in particular the body part, may have an insert. The at least one magnet can be fixed in the insert. Preferably, the insert is made of a non-ferromagnetic material, in particular plastic. Preferably, the insert has a permeability of> 4, and particularly preferably> 50. Due to the insert, the rest of the latch element, in particular the remaining body part, can be made of a ferromagnetic material, without damaging the function of at least one magnet. The insert can, for example, be screwed to the body part.

It is conceivable that the blocking element is maintained in the first position by the effect of the magnetic force. The magnetic force that moves the blocking element to the second position may be in particular that which keeps the blocking element in the second position.

The blocking element may preferably be under the influence of the magnetic force through the position of the latch element that interacts with the blocking element by means of the magnetic force. The latch element that has an influence on the blocking element through the drag-in and / or friction closure is in particular the latch element that does not interact with the blocking element. The latch element that has an influence on the blocking element through the drag-in and / or friction closure, may in particular be the latch.

Thus it may be that in the protruding position of the latch, the locking element is held in the first position by a drag in form and / or friction drag. In the retracted position of the latch, the drag-on and / or friction closure with the locking element may be voided. The drag-on and / or friction closure can only be established indirectly between the locking element and the latch. In this way, the drag-and-friction closure can be established, for example, between the slide and the locking element or between the lock bolt and the locking element. The drag and form or friction closure can be in particular a friction drag closure.

Thus, the blocking element can be held in the first position by a drag in form and / or friction drag. In this regard, it may be in particular that the drag-and-or-friction closure is annulled by a movement of the latch in the direction towards the retracted position or in the retracted position. If the drag-on closure of form and / or friction is annulled, then the magnetic force, which with an additional retracted latch acts on the blocking element, can move the blocking element to the second position. In this way, the drag-in form and / or friction closure can exert a greater force on the blocking element than the magnetic force acting with the additional latch retracted on the blocking element.

Additionally or alternatively, the magnetic force that moves the blocking element to the first position can keep the blocking element in the first position. The magnetic force to keep the locking element in the first position can be annulled by a movement of the additional latch in the direction towards the retracted position or in the retracted position. If the drag-in form and / or friction closure and / or the magnetic force to keep the blocking element in the first position no longer act on the blocking element, then the blocking element can be moved to the second position, where in particular the blocking element moves to the second position due to the effect of a magnetic force.

Additionally or alternatively, the blocking element can be held in the first position through the force exerted by the force accumulator.

If, by retracting the latch element, in particular the additional latch, a magnetic force or an intensified magnetic force acts on the blocking element, such that the blocking element tends to moving to the second position, then with a movement of the blocking element to the second position the force accumulator can be charged, in particular the spring. The magnetic force acting with the retracted latch element, in particular the additional latch, on the locking element, may be greater than the force of the force accumulator. If the additional latch is in the protruding position, then the magnetic force, which acts on the blocking element, may be less than the force of the force accumulator, such that the blocking element remains in the first position. Additionally, it may be that only with the cancellation of the drag-and-friction closure, the magnetic force acting with the retracted latch element, in particular with the additional latch, on the blocking element, can the element move Lock to second position.

It may be that the force of the weight of the blocking element supports or causes the movement of the blocking element to the first position or the second position. Thus, for example, it is conceivable that the magnetic force acting with the retracted latch element, in particular the additional latch, on the locking element, is greater than the force of the force accumulator and the force of the weight. If the additional latch is in the outstanding position, then the magnetic force acting on the blocking element may be less than the force of the force accumulator and the force of the weight of the blocking element, such that the element of Lock remains in the first position.

Alternatively, the locking element can be held in the first position by means of a latch cam. If the additional latch moves back, then the latch cam releases a movement of the locking element to the second position.

It is possible that the latch element, which cooperates with the blocking element through the magnetic force, has a first magnet. The first magnet can attract the blocking element. The first magnet can be made as a first permanent magnet. The latch element, which cooperates with the blocking element through the magnetic force, can also have a second magnet, or in particular a second permanent magnet. The second magnet can repel the blocking element. By using the permanent magnet, the lock can be designed as a purely mechanical lock. In the latch element it may be preferably the additional latch.

The first magnet, with a movement of the blocking element from the first position to the second position, can be arranged at least partially in the direction of movement of the blocking element. In this regard, in particular the latch element, which cooperates with the locking element through the magnetic force, is in the retracted position.

Additionally or alternatively, the second magnet, with a movement of the blocking element from the second position to the first position, can be arranged at least partially in the opposite direction to the direction of movement of the blocking element. In particular, in this respect the latch element, which cooperates with the locking element through the magnetic force, is in the outstanding position.

It is conceivable that the first magnet and the second magnet are arranged in such a way on the latch element, that in the retracted position the first magnet is at a smaller distance from the blocking element than the second magnet and / or that in the Outstanding position the second magnet is at a smaller distance from the locking element than the first magnet. If this refers to the retracted position and / or the outstanding position, it depends on whether the latch or the additional latch interacts with the locking element through the magnetic force.

The first magnet and the second magnet can be made with different lengths. The spatial extent in the direction of movement of the latch element, in particular the additional latch. In this way it is possible to vary the moment in which the blocking element changes from the first to the second position or vice versa. For example, the first magnet may be longer than the second magnet.

Preferably, the magnet of the latch element, which moves the locking element to the second position, in particular the first magnet, is arranged in such a way and / or has a length such that the blocking element already changes to the second position while The latch element, in particular the additional latch, is still moving in the direction of the retracted position. This means that the locking element already occupies the second position, before the latch element has fully retracted.

The lock may comprise a particularly still contact surface. The blocking element in the second position may be in contact with this contact surface. This prevents contact with the latch element itself.

The blocking element in the second position may be distanced from the latch element, with which the blocking element interacts through the at least one magnetic force. Additionally or alternatively, the blocking element in the first position may be distanced from the latch element, with which the blocking element interacts through the at least one magnetic force. Preferably, the blocking element is always distanced from the latch element, with which the blocking element interacts through it. minus a magnetic force, in particular the additional latch. Particularly preferably, the locking element is distanced from both the latch and the additional latch.

A lock element housing can be provided in the lock to guide the blocking element in its movement from the first to the second position.

It is possible that the housing of the blocking element, which serves to guide the movement of the blocking element, comprises the contact surface. With this, two functions can be integrated into the same element. It may be that the housing of the locking element comprises the contact surface and / or the spring guide.

Particularly preferably, the magnet of the blocking element is disposed on an end surface of the blocking element. The end surface may be oriented towards the latch element, with which the locking element interacts through the at least one magnetic force. In particular, the end surface may be oriented towards the additional latch.

In particular, the contact surface may be arranged such that at least one stop surface of the blocking element is arranged laterally and / or below the end surface, where the stop surface serves for contact of the blocking element with the contact surface. In this way a preferred spatial configuration can be achieved.

Preferably, it is provided that the blocking element is disposed in a torsion-resistant manner in the lock case for this purpose, the blocking element may have at least one guide surface. Additionally or alternatively, the housing of the locking element can be disposed in a torsion-resistant manner in the lock case. For this, the housing of the blocking element may comprise at least one fixing means, preferably two fixing means. The fixing means are used to fix the housing of the locking element to the lock housing. Due to the torsion-resistant arrangement, it is ensured that the locking element can fulfill the function of preventing or allowing the locking state of the lock, in particular that the blocking element can only move between the first and second positions.

The locking element in the first position can be found in effective relationship with the lock of the lock. In particular, friction contact between the locking element and the lock bolt can occur. In this regard, the locking element can be found within a notch of the lock bolt. The friction contact between the locking element and the lock bolt can be advantageously configured in such a way that the friction contact can only be canceled by a retraction of the lock bolt to a position that goes beyond the opening position. inside the lock case. To ensure friction contact between the locking element and the lock of the lock, the lock of the lock can either be prestressed in the extension direction by the effective relationship with the slide or by a separate spring element, and the friction contact can only be released, if the lock bolt retracts at least a certain distance beyond the opening position inside the lock case.

The retraction of the lock of the lock to the position that goes beyond the opening position within the lock case can be produced by a sliding movement of the slide, and the sliding movement of the slide can preferably be made to push latch back inside the lock case. Another advantage is achieved by means of an effective relationship between the slide and the lock of the lock, which is performed as a sliding guide. The direction of movement of the slide and the direction of movement of the lock bolt form a right angle to each other, and by the sliding guide the vertical movement of the slide transcends in the horizontal movement of the lock bolt.

The slide can have a slide extension, in which the slide guide element can be introduced when the slide moves in such a way that the lock bolt retracts inside the lock case to a position that goes further beyond the opening position. The slide extension can be arranged at the end of the slide, in which the slide guide element is in the slide when the lock of the lock is in the retracted position, which reflects the opening position of the lock of the lock. If the slide lifts slightly, then the slide guide element enters the slide extension and the lock bolt retracts a small distance beyond the opening position inside the lock case. This releases the friction contact between the locking element and the notch in the lock of the lock, and the blocking element can release the lock of the lock. Subsequently the lock of the lock can extend completely out of the lock case.

A contact element can be arranged in the latch, and the contact element, when pushed inwards, enters into an effective relationship with the slide, such that the slide makes a stroke movement. The contact element can be made as a roller, which is rotatably disposed in the latch. The arrangement of the contact element, in particular the roller, in the latch can be effected through a latch rod, and the contact element is mechanically connected through the latch rod with the latch and together with the movement of the latch it moves correspondingly. The slide can have a contact surface, which is contoured in such a way that the slide makes the stroke movement when the contact element touches the contact surface. The contact surface forms an edge, and if the latch moves with the contact element against the edge of the contact surface, the stroke movement is introduced into the slide. In this, the roller rolls on the contact surface, particularly along the edge. The movement of the slide and the contact element is guided in the movement of insertion of the latch in the lock case, and the slide is guided in the direction of movement perpendicular to the direction of movement of the latch in the lock case. . Therefore, the movement of the latch and the contact element is reversed by 90 °, and the slide moves vertically through the lock case, when the movement of the latch and the contact element develops in the horizontal plane .

A spring element can be arranged between the lock case and the slide, whereby the slide is prestressed in the position corresponding to the closed position of the lock bolt. If the latch is pushed with the contact element inside the lock case and the contact element is brought into contact with the contact surface on the slide, then the slide rises slightly against the pretension of the spring element . If the additional latch is also in a state pushed into the lock case, and if the slide rises slightly against the pretension of the spring element, then the slide guide element enters the slide extension , and the lock of the lock retracts further into the lock case beyond the opening position. This releases the friction contact between the locking element and the lock of the lock. If the latch is subsequently returned to the extended position outside the lock case, for example, when the lock is closed in the antagonist closure element, and the latch engages in the corresponding opening in the antagonist closure element, then at the same time the lock of the lock extends out of the lock case. The extension movement is initiated by the spring element between the lock case and the slide.

Additionally, an electronic actuator unit can be provided, which can be put into an effective relationship with the slide for the movement of the slide. The actuator unit can be connected to a central unit in a building, for example, through a cable and / or radio connection, for example, to bring the lock of the lock to the remote control opening position. Additionally, a sensor unit can be provided that is configured to detect the position of the additional latch and / or the locking element. The sensor unit can also be connected to the control unit, and information regarding the position of the additional latch and / or the locking element can be consulted. The sensor unit can be made at least as a push-button switch, which mechanically cooperates with the additional latch and / or with the locking element.

In Figure 1, the reference character 1 designates a lock with a lock box 10, which can be inserted into a door leaf. In the lock box 10 a latch 11 is shown in an outstanding position outside the lock box 10. The latch 11 can be retracted inside the lock box 10 to a retracted position, for example, by a door handle that can being housed in a latch housing 28. Additionally, the latch 11 can be pushed into the lock box 10, when the lock 1 comes into contact with an antagonist closing element not shown in greater detail, for example, a closing plate, which is inserted, for example, in a door frame or a fixed sheet. If the latch 11 collides with the antagonist closing element, the latch 11 is pushed into the lock box 10, and if the fixed blade is in a closed position, then the latch 11 returns out of the lock box. lock 10 and can engage in a corresponding opening in the antagonist closure element. The additional latch 14 remains in the retracted position. The antagonist closing element does not have any recess for the additional latch 14, in which the additional latch 14 can extend when the door is closed. The latch 11 is made in a manner known as a cross latch and is not described in more detail in its operation. The additional latch has a body part 33 and a head piece 38 pivotally supported on the first.

Additionally, the lock 1 has a slider 12 housed in a longitudinally movable manner in the lock box 10. The slider in Figure 1 is in a first position. The slide 12 can be effectively connected to the latch 11, when the latch 11 is pushed back into the lockbox 10 when the door is slammed and the latch 11 is brought into contact with the antagonist closing element . In this regard, a runner movement can be introduced in the slide 12, which in the representation is carried out in the vertical plane, as indicated by the double date on the slide 12. In the lock 1 a lock bolt is also provided 13, which also cooperates with the slide 12, and with the movement of the slide 12 can move between a locked position and an open position (see Fig. 1). The effective relationship between the slide 12 and the lock bolt 13 is formed by a slide guide, and the direction of movement of the slide 12 and the direction of movement of the lock bolt 13 enclose a right angle to each other, and by means From the slide guide a vertical movement of the slide 12 can be converted into a horizontal movement of the lock bolt 13, to move the lock bolt 13 between the locked position and the open position. In the locked position (see Figure 5), the lock bolt 13 is in an outstanding position outside the lock case 10, and in the open position (see Figure 1) the lock bolt 13 is located in a retracted position within the lock box 10. The slide guide as an effective relationship between the slide 12 and the lock bolt 13 has a collar 20 on the slide 12, in which the slide guide element 21 is guided If the slider 12 moves in the vertical plane down to a second position, then the lock bolt 13, therefore, can extend out of the lock case 10.

In the second position of the slide 12, the lock 1 can cause a door interlock. In the second position of the slide 12, the lock is in the locked state. The interlocking is achieved, on the one hand, by the locking position of the lock bolt 13. The interlocking is achieved, on the other hand, because the latch 11 is locked, if the slider 12 is in the second position. If the latch 11 is locked, then the latch 11 cannot move to the retracted position by a pressure of the antagonist closing element. Therefore, the latch 11 acts in the second position of the slide 12 as an additional bolt.

By the stroke movement described above, the slide 12 reaches a third position.

Additionally, the lock 1 has an additional latch 14, which cooperates with a locking element 15. The additional latch 14 can move between an outstanding position, shown in Figure 1, and a retracted position. The additional latch is pushed into the retracted position by means of the antagonist closing element and remains there, even if the door leaf is in the closed position. The locking element 15 is arranged in such a way that the lock bolt 13 cannot move to the locked position if only the latch 11 or the additional latch 14 is pushed back into the lock case 10. Rather, first a movement process has to take place, in which first the latch 11 has to be moved from the protruding position to the retracted position and the additional latch 14 also has to be moved from the outstanding position to the retracted position, where these two movements They have to overlap. The blocking element 15 can be moved between a first position and a second position. The blocking element 15 moves to the second position due to the effect of a magnetic force. The magnetic force acts between the locking element 15 and the additional latch 14. For this, a magnetic element 17 is arranged in the locking element 15. The additional latch 14 presents the part of body 33, which is always inside the lock box 10. The body part 33 is made of ferromagnetic material, such that there is a force of magnetic attraction between the magnetic element 17 and the body part 33. The magnetic element 17 is disposed on an end surface 18 of the blocking element 15.

The locking element 15 is arranged completely within the lock box 10. The locking element 15 is arranged in such a way that it can be put into an effective relationship with the lock bolt three. For this, the locking element 15 is housed inside the lock box 10 in a locking element housing 25 in a mobile manner. The direction of movement of the locking element 15 coincides with the direction of movement of the slide 12, without entering into effective relationship with the slide 12. In the arrangement shown, the lock bolt 13 is in the open position, in the that the lock bolt 13 is retracted within the lock box 10. A notch 16 is provided in the lock bolt 13, and in the shown open position of the lock bolt 13, the notch 16 is superimposed with the locking element 15. The locking element 15 is partially in the first position in the recess 16. The latch 11 and the additional latch 14 are shown in an outstanding arrangement outside the lock case 10. The additional latch 14 is located in an effective relationship with the blocking element 15. Due to the interaction between the additional latch and the blocking element 15, the blocking element 15 is introduced into the Notch 16 in the lock bolt 13. The locking element is in the first position and prevents a movement of the lock bolt 13 to the locked position. Between a locking edge 16a of the notch 16 and the locking element 15, frictional drag contact can occur, blocking the locking element 15 in the position shown. The contact force between the locking edge 16a of the notch 16 of the lock bolt 13 and the locking element 15 is produced because a spring element 23 presses the slide 12 down, and through the colisa 20 and the Sliding guide element 21, the lock bolt 13 is pressed in the direction of its locked position, when the lock bolt 13 is pushed out of the lock case 10.

The movement of the lock bolt 13 outside the lock box 10 is prevented by means of the locking element 15, which in the first position engages in the notch 16. Due to the pretension, there is a contact force between the locking edge 16a and the blocking element 15, such that the blocking element 15 remains in the position shown due to the friction contact. If the additional latch 14 is pushed into the lock case 10, the frictional force between the locking edge 16a of the notch 16 and the locking element 15 is greater than the magnetic force, with which the locking element 15 it is drawn towards the additional latch 14. As a result, the locking element 15 remains in the recess 16, even when the additional latch 14 is pushed into the lock case 10.

Only when the additional latch 14 and the latch 11 are pushed together inside the lock case 10, can the lock element 15 be put out of engagement with the groove 16 in the lock bolt 13. If the latch 11 is pushed into the lock box 10, a contact element 22 made as a roller comes into contact with a contact surface 12a in the slide, which is made as an edge. The contact element 22 is introduced below the slide 12 in a recess 29 of the contact surface 12a, and the slide 12 rises slightly under compression of the spring element 23 and moves to the third position. In this, the slide guide element 21 enters a slide extension 21a, whereby the pretension of the lock bolt 13 in the locked position is canceled, and the lock bolt 13 can be further retracted by a small distance within of the lock box 10. In this regard, by already canceling the contact force between the blocking edge 16a and the blocking element 15 it is sufficient to achieve that, by the effect of the magnetic force, the blocking element 15 moves to the second position towards the additional latch 14 pushed inwards. In the second position, the locking element 15 no longer prevents the lock bolt 13 from extending to the locking position. Therefore, the locking element 15 also allows a movement of the slide 20 to the second position.

If the latch 11 is brought back to an outstanding position outside the lock case 10, for example, if the latch 11 engages in the corresponding opening in the antagonist closure element, then the slider 20 can move to the second position. Therefore, the lock bolt 13 can extend out of the lock box 10 and the lock 1 can be nailed to the antagonist closing element.

To reopen the lock, by means of a door handle not shown in greater detail, torsion can occur inside the latch housing 28, to move the slide 12 again against the spring element 23. In this respect, the door handle it can be arranged, for example, only on the inner side of the room, and the lock 1 cannot be opened from the outside of this room. Additionally, by means of a closing cylinder, which can be inserted into a closing cylinder housing 30, a drive element 31 can be activated in the slide 12, to move the slide 12 back against the spring element 23. With the movement of the slide 12 upwards, the slide guide element 21 can be brought back to the position shown, and the lock bolt 13 retracts back into the lock box 10.

Figure 2 shows the detail view characterized with A in Figure 1. The interaction between the latch 11 and the slide 12 is shown. The latch 11 is arranged in a latch rod 26, and can be moved in a direction of horizontal movement between an outstanding position of the lock box 10 and a retracted position inside the lock box 10. Through the latch rod 26, the contact element 22 is connected with the latch 11, which is realized as roller and which is rotatably housed in the latch rod 26. A section of the slide 12 is also shown in the area of the contact surface 12a in the slide 12, with which the contact element can be contacted 22

The representation shows the latch 11 in an outstanding position outside the lock case 10. For example, if the latch 11 is pushed back into the lock case 10 when colliding with an antagonistic closing element, then the contact element 22 wheels on the contact surface 12a and enters an undercut 29 in the slide 12. Because of this, the slide 12 moves upward in the direction of the arrow shown, to move the slide guide element 21 into the slide extension 21a, according to the above description. The slide 12 is guided in the vertical plane inside the lock box 10 by means of guide elements 32, and the movement of the slide 12 is limited to a lifting movement. The latch 11 is prestressed in the prominent position of the lock case 10 by a latch spring 27.

Figure 3 shows a detailed view of section B shown in Figure 1. The locking element 15 is shown, which is in relation to interaction with the additional latch 14. The locking element 15 comprises the end surface 18 , which in the arrangement shown as a cam interacts with a latch cam 19, which is mounted on the additional latch 14. The additional latch 14 is prestressed in the protruding position outside the lock case 10 by means of an additional latch spring 24. The end surface 18 and the latch cam 19 face end to end, and the locking element 15 is therefore maintained in the arrangement shown.

Additionally, the rear part of the locking element 15 is inside the notch 16 provided in the lock bolt 13. In this regard, a friction contact is maintained between the locking edge 16a in the notch 16 and the end rear of the locking element 15, since in the position shown the lock bolt 13 is prestressed in an outstanding position of the lock box 10.

If then the additional latch 14 is pushed into the lock box 10, and the tip 18 is put out of engagement with the latch cam 19, the locking element 15 remains in the position shown, despite the magnetic force that it acts in the direction of the additional latch 14, since friction contact prevails between the blocking edge 16a and the blocking element 15. The blocking element 15 is housed in a housing of blocking element 25, which is disposed within the lock box 10. In the lock element housing 25, the lock element 15 is made mobile in the vertical plane, and only when the contact force between the lock edge 16a and the lock element 15 is cancel, the magnetic force can move the locking element 15 in the direction of the additional latch 14 pushed inside the lock case 10, to release the exclusion movement of the lock bolt 13 out of the lock case adura 10. If the pushing force is annulled into the additional latch 14 inside the lock case 10, because the additional latch is brought out of contact with the antagonist closing element, and if the additional latch 14 returns to be guided to the position shown by the additional latch spring 24, then the tip 18 again meets the latch cam 19. At the same time, the locking element 15 re-enters the recess 16 in the lock bolt 13 , and the displayed position of the locking element 15 is restored again.

This ensures a safe operation of the movement of the bolt of the lock bolt, and the lock bolt 13 can only protrude out of the lock box 10, if both the latch 11 and the additional latch 14 are pushed at the same time inside the lock box 10 and only the latch 11 protrudes from the lock case, since only the latch 11 has a corresponding opening in the antagonist closing element.

In a different way from the embodiment of figures 1 to 3, a magnet of the additional latch 14 can be arranged in the latch cam 19 (in figures 1 to 3 it is not shown). The magnet of the additional latch 14 is arranged in such a way in relation to the magnetic element 17 of the blocking element 15, that the magnet and the magnetic element 17 attract each other. By effect of the magnet, with a movement of the additional latch 14 the magnetic force acting on the magnetic element 17 of the blocking element 15 is modified.

A variant of the embodiment shown in Figures 1 to 3 is shown in Figures 4 to 7 as a second embodiment. If it is not explicitly described in the following, the second embodiment corresponds to the first embodiment of Figures 1 to 3. In Figures 4 and 5 these are sectional representations.

In the additional latch 14 a first magnet 34 and a second magnet 35 are arranged. The first magnet 34 is arranged in such a way in relation to the magnetic element 17 of the blocking element 15, that the first magnet 34 and the magnetic element 17 are attracted mutually. For example, the north pole of the first magnet 34 points down and the south pole of the magnetic element 17 points up. The second magnet 35 is available. In relation to the magnetic element 17, the second magnet 35 and the magnetic element 17 mutually repel each other. For example, the south pole of the second magnet 35 points down and the south pole of the magnetic element 17 points up.

The additional latch 14 is made without latch cam 19. Instead of the latch cam 19, the magnetic repulsion force between the second magnet 35 and the magnetic element 17 serves to push the locking element 15 into the recess 16, when the lock bolt 13 is in the open position. In this regard, the additional latch 14 is in the prominent position. In the protruding position of the additional latch 14, the second magnet 35 disposes the vertical plane on the magnetic element 17 (see Figure 4). The second magnet 35 is in this position of the additional latch 14 closer to the magnetic element 17 than the first magnet 34. The second magnet 35 is in the protruding position of the additional latch 14 against the direction of movement of the locking element. 15 with a movement of the blocking element from the second position to the first position.

If the door is open, the magnetic repulsion force acts on the blocking element 15, which exists between the second magnet 35 and the magnetic element 17, as well as the friction contact due to the contact on the blocking edge 16a. This is shown in Figure 4. Therefore, the locking element 15 remains in the first position.

A section of Figure 4 is shown in Figure 5, when the additional latch 14 is in the retracted position with the door closed. In Figure 5, the first magnet 34 is arranged in the vertical plane on the magnetic element 17. The first magnet 34, therefore, is closer to the magnetic element 17 than the second magnet 35. Therefore, the first magnet 34, in the retracted position of the additional latch 14, is arranged in the direction of movement of the blocking element 15 with a movement of the blocking element 15 from the first position to the second position. After the friction contact with the locking edge 16a is canceled by the retracted position of the latch 11, in the retracted position of the additional latch 14 the blocking element 15 can move from the first to the second position due to the force of attraction magnetic In Figure 5, the locking element 15 is in the second position.

If only the additional latch 14 is retracted, then the repulsion force of the second magnet 35 no longer acts on the blocking element 15, but the blocking element 15 is attracted by the first magnet 34. However, the friction contact it acts on the blocking element 15, such that the blocking element 15 remains in the first position.

If only the latch 11 is retracted, then the friction contact is canceled, but the blocking element 15 due to the repulsive force of the second magnet 35 remains in the first position. Only when both the latch 11 and the additional latch 14 have been retracted, is the friction contact canceled as well as the magnetic repulsion force is replaced by the magnetic attraction force, such that the locking element 15 moves to the second position.

In both the first position of the blocking element 15 according to Figure 4 and also in the second position of the blocking element 15 according to Figure 5, the additional latch 14 and the blocking element 15 are mutually spaced apart. The locking element housing 25 has a contact surface 36, in order to prevent the blocking element 15 from contacting the first magnet 34, despite the magnetic attraction force between the first magnet 34 and the magnetic element 17.

The locking element 15 has stop surfaces 37, which in the second position are brought into contact in a manner with the contact surface 36 and thus limit the movement towards the additional latch 14. The stop surfaces 37 they are arranged below the end surface 18 of the locking element 15.

The magnetic element 17, the first magnet 34 and the second magnet 35 are made as permanent magnets. In the exemplary embodiment of Figures 4 and 5, the end surface 18 is made flat and not as a cam, since a direct contact with the additional latch 14 is missing.

The body part 33 has an insert 39 of plastic material, in which the first magnet 34 and the second magnet 35 are fixed. The first magnet 34 in the direction of movement of the additional latch 14 is longer than the second magnet 35 The first magnet 34 already during the movement of the additional latch 14 is arranged in the vertically retracted position on the blocking element 15. Therefore, as soon as the friction contact has been canceled, already during the movement of the additional latch 14 to the retracted position, the blocking element 15 can reach the second position. The lock bolt 13 only extends when the contact element 22 is brought out of contact with the slide 12. This only happens when the door has been closed.

In figures 6 and 7 the blocking element 15 and the blocking element housing 25 are shown in respectively different perspectives. In the representation of the blocking element 15 the magnetic element 17 has been omitted. The blocking element housing 25 has at least one fixing means 40, with which the blocking element housing 25 is fixed in a manner resistant to the torsion in the lock box 10. In this regard, one of the fixing means 40 is made as a screw hole and another as a nose, with which The locking element housing can engage in the lock box 10. The blocking element 15 has guide surfaces 41 with which it is torsionally guided with corresponding conduction surfaces 43 of the blocking element housing 25 and can deviate through forces.

The locking element 15 has an extension 42 to engage in the groove 16.

A variant of the embodiment shown in Figures 4 to 7 is shown in Figures 8 to 12 as a third embodiment. If it is not explicitly described in the following, the third embodiment corresponds to the second embodiment of Figures 4 to 7. In Figures 8 to 10 these are sectional representations. A section similar to that of figure 4 is shown in figure 8, when the additional latch 14 with the door open is in the projecting position. In figure 9, the section of figure 8 is shown, when the additional latch 14 with the door closed is in the retracted position.

In the additional latch 14 only a first magnet 34 is arranged. The first magnet 34 is arranged in such a way in relation to the magnetic element 17 of the blocking element 15, that the first magnet 34 and the magnetic element 17 attract each other. For example, the north pole of the first magnet 34 points up and the south pole of the magnetic element 17 points up.

The additional latch 14 does not serve to move the locking element 15 to the first position. Rather, for this a spring 44 is arranged in the locking element housing 25, which pushes the locking element 15 to the first position. The blocking element housing 25 for this may comprise a first bearing surface 47, on which the spring 44 rests. The blocking element 15 has a corresponding second bearing surface 48, with which the spring 44 comes into contact. The spring 44 pushes the locking element 15 through the second bearing surface 48 to the first position. The first bearing surface 47, therefore, limits the spring 44 at the end oriented in the opposite direction to the lock bolt 13 of the spring 44. The second bearing surface 48, therefore, limits the spring at the oriented end. towards the lock bolt 13 of the spring 44.

The spring 44 is guided in the locking element housing 25. The locking element housing 25 has a first spring guide 45 and the locking element 15 has a second spring guide 46, to arrange the spring 44 stationary .

In Figure 8, the locking element 15 is in the first position. In Figure 9, the lock is in the locked state, in which the locking element 15 is in the second position. In the second position, the spring 44 is compressed and therefore tensioned. In the second position, the locking element 15 is attracted by the first magnet 34 of the additional latch 14 retracted. Therefore, the magnetic attraction force of the magnetic element 17 and the first magnet 34 exceeds the spring force 44, when the additional latch 14 is in the retracted position. On the other hand, if the additional latch 14 is in the outstanding position, then the spring force 44 exceeds the magnetic attraction force of the magnetic element 17 and the first magnet 34.

The force of the weight of the blocking element 15 can support the force of the spring 44. Thus, the magnetic attraction force of the magnetic element 17 and of the first magnet 34 can overcome the force of the spring 44 and the weight force of the blocking element 15 , when the additional latch 14 is in the retracted position. On the other hand, if the additional latch 14 is in the protruding position, then the spring force 44 and the weight force of the locking element 15 exceeds the magnetic attraction force of the magnetic element 17 and the first magnet 34.

In Figure 8, the locking element 15 is arranged with the extension 42 in the recess 16 of the lock bolt 13. As shown in Figure 11, in the third embodiment example the magnetic element 17 and the extension 42 is not They are arranged directly overlapping, but are slightly offset from each other. Because of this, in the sectional representation in Figure 8, although the magnetic element 17 is shown in section, the extension 42 is not shown, which in Figure 8 is hidden by the lock bolt 13.

If only the additional latch 14 is retracted, then the locking element 15 is attracted by the first magnet 34. However, the friction contact acts on the blocking element 15, such that the blocking element 15 remains in the first position.

If only the latch 11 is retracted, then although the friction contact is canceled, the locking element 15 still remains in the first position due to the force of the spring 44 and the lack of the magnetic attraction force between the magnetic element 17 and the first magnet 34. The force of the weight of the locking element 15 can support the permanence in the first position. Only when both the latch 11 and the additional latch 14 have been retracted, the friction contact and the magnetic attraction force between the magnetic element 17 and the first magnet 34 can overcome the spring force 44 and, if necessary , the weight force of the blocking element 15, such that the blocking element 15 moves to the second position.

The present invention is not limited in its embodiment to the preferred embodiment example described above. Rather, multiple variants are conceivable that make use of the represented solution, even with basically different embodiments. All features and / or advantages, including constructive details or spatial arrangements, which are derived from the claims, the description or the drawings, can be substantial for the invention, both individually and in the most diverse combinations, without that the framework of the present invention defined by the appended claims be abandoned.
