Definitions

• the present invention relates to a lock with a lock case in which a latch is movably received in a retracted from the lock case and in a retracted position in the lock case, wherein a longitudinally movably received in the lock case slide is provided with the case in operative connection Can be brought when the case is pushed back into the lock case, and wherein a lock bolt is provided which cooperates with the slider and is movable with movement of the slider between a locking position and an open position, and wherein an additional trap is provided, which with a Locking element cooperates, wherein the locking 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.
• a generic type lock with a lock case in which a case is movably received between a protruding from the lock case and a retracted into the lock case position.
• 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.
• a lock bolt is accommodated in the lock case, which interacts with the slide via a slide guide. If the slide moves in the vertical direction, the lock bolt can move between one in the lock case
• the lock has an additional case, which cooperates with a blocking element, and the blocking element is arranged such that the lock bolt is prevented in a pressing back of the case or the additional case in the lock case from moving into the blocking position.
• the lock bolt can not be easily moved out of the lock case.
• it is not sufficient to push back the case in the lock case since the slide passes through the moving roller against the contact surface on the slider and this slightly lifts, however, the projection of the slider comes against the disc-shaped stop element, which is received on the additional 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.
• Unauthorized removal of the lock bolt from the lock case can already be triggered manually by the additional trap is pressed and by - for example, accidentally - the trap is also easily returned to the lock case. A security against unauthorized extension of the lock bolt from the lock case is thus not sufficiently given.
• the object of the present invention to improve a lock with a trap and an additional trap for securing the operation of a latch movement, in particular the object of the present invention is to improve the safety device of the latch movement in such a way that prevents unauthorized extension of the latch bolt is.
• the invention includes the technical teaching that the blocking element has an operative connection with the lock bolt, wherein the Wirkver- connection is formed by a recess in the lock bolt, in which the locking element can be introduced by the additional latch is transferred in a protruding from the lock case position in which the blocking element remains in the recess when the additional latch is pressed back into the lock case by frictional engagement.
• the invention is based on the idea not to bring the locking element into operative connection with the slider, but the locking element is brought into operative connection with the lock bolt.
• the security against unauthorized extension of the lock bolt from the lock case is further increased, for example when the door leaf in which the lock is installed, is open, so that both the case and the additional case are manually accessible.
• the sensitivity for triggering the movement of the lock bolt from the lock case is further reduced, and even a slight lifting of the slider by the interaction with the case is not sufficient to release the connection between the locking element and the lock bolt.
• connection is formed according to the invention by a frictional connection, and even if the additional latch is actuated, and the blocking element could be moved out of the recess from the lock bolt, the blocking element remains in the recess in the lock bolt, as by a slight lifting of the slide Frictional connection between the lock bolt and the locking element is not yet solved.
• the reason for this lies in the operative connection between the slider and the lock bolt, which is subject to a slight play that must first be overcome in order to trigger a movement of the lock bolt when the slider is moved in the lock case.
• the frictional engagement between the locking element and the lock bolt can advantageously be designed such that the frictional engagement can only be canceled by retracting the lock bolt into a position extending beyond the open position into the lock case.
• the lock bolt can be biased either by the operative connection with the slider or by a separate spring element in the extension direction, and the frictional engagement can be solved only when the lock bolt at least a little way over the open position pulled into the lock case.
• the pulling of the lock bolt into the position which extends beyond the open position into the lock case can be produced by a stroke movement of the slide, and the stroke movement of the slide can preferably be effected by pushing the latch back into the lock case.
• a spring element can be provided which biases the blocking element against the additional trap, wherein the blocking element can be brought out of the recess by the spring element. The spring element thereby biases the blocking element in the direction of the additional trap with a force which is less than the force which is achieved by the frictional engagement between the blocking element and the lock bolt.
• the blocking element may have a contact cam, via which the blocking element is prestressed by the spring element against the additional trap.
• the additional case may have a case cam which can be brought into coincidence with the contact cam of the blocking element when the additional case protrudes from the lock housing. If the additional latch is pressed into the lock housing, the contact cam of the locking element is no longer in coincidence with the case cam of the additional latch, so that upon release of the frictional engagement between the locking element and the lock bolt, the blocking element is moved by the spring element in the direction of the additional latch.
• the spring element can be designed as a helical compression spring and arranged around the blocking element.
• Another advantage results from an operative connection between the slide and the lock bolt, which is designed as a sliding guide, and the slotted guide can have a slide introduced in the gate and arranged on the lock bolt sliding guide element. The direction of movement of the slider and the direction of movement of the lock bolt form a right angle to each other, and by the slide guide, the vertical movement of the slider is transferred to the horizontal movement of the lock bolt.
• the gate may have a gate extension, in which the gate guide element is then inserted, when the slider is moved such that the lock bolt is retracted into a position beyond the open position in the lock case.
• the gate extension can be arranged at the end of the gate on which the slide guide element is located in the gate when the lock bolt is in the retracted position, which reflects the open position of the lock bolt. If the slider is slightly raised, then the link guide element enters the link extension, and the lock bolt is pulled by a small way beyond the open position into the lock case. As a result, the frictional engagement between the locking element and the recess in the lock bolt is released, and the locking element can release the lock bolt. Subsequently, the lock bolt can be fully extended out of the lock case.
• a contact element can be arranged on the latch, and the contact element comes into operative connection with the slide when the latch is pressed in, so that the slide executes a lifting movement.
• the contact element may be formed as a roller which is rotatably arranged on the trap.
• the arrangement of the contact element, in particular the roller, on the case can be done via a latch shaft, and the contact element is mechanically connected via the latch shaft with the case and is moved along with movement of the trap accordingly.
• the slider may have a contact surface which is contoured such that the slider performs the lifting movement when the contact element comes against the contact surface.
• the contact surface forms an edge, and if the trap is moved with the contact element against the edge of the contact surface, the lifting movement is introduced into the slide.
• the movement of the slide and the contact element is guided in the insertion movement of the case in the lock case, and the slider is guided in the direction of movement perpendicular to the direction of movement of the case in the lock box th. Consequently, the movement of the latch and the contact element is deflected by 90 °, and the slider moves vertically through the lock case when the movement of the latch and the contact element in the horizontal.
• a spring element may be arranged, through which the slide is biased into the position corresponding to the locking position of the lock bolt. If the case is pressed with the contact element in the lock case and the contact element comes into contact with the contact surface on the slide, the slider is slightly raised against the bias of the spring element.
• the actuator unit may be connected to a center in a building, for example via a cable and / or a radio link, thus the slide can be moved by remote control, for example, to transfer the lock bolt by remote control in the open position.
• a sensor unit may be provided which is designed to sense the position of the additional latch and / or the blocking element.
