DESCRIPTION

Panic lock

The invention relates to a panic lock with a closing cylinder, a lock housing in which a latch is arranged, which locks in a first position, in which it protrudes from the lock housing, and which can be removed to a second position unlocked inside the lock housing, a trigger, which protrudes from the lock housing and can be passed through a first locking element to a locked position and an unlocked position, a slider that can move inside the lock housing in a translational movement to a first and second position and having a slider end, which in the second position of the slider is in contact with the first locking element and cancels the trigger lock position, the trigger being slider in a functional connection with the latch so that in the first locked position of the latch, during the movement of the first position With the second position, the slider moves the latch to the second position.

In document 39 38 655 C2 an automatic interlocking lock is described, which, after unlocking, passes a latch to a locked position with the help of a prestressed slider while blocking a cross trigger. In the opposite direction, the slider can move backwards both by means of a door handle and by a closing cylinder, so the lock is unlocked. Here, the locking position of the cross trigger and the latch starts automatically, when the cross trigger and an intended auxiliary trigger are actuated in a logical sequence, corresponding to the door's closed position. What is essential in this embodiment of the lock is the slider that can be passed through a control trigger to a self-locking. One of the drawbacks of the lock that is disclosed here is that every time the door is closed, in addition to the cross trigger lock, an advance of the latch also takes place. As a rule, this produces considerable noise. In addition, the switching logic of the auxiliary trigger and the cross trigger can be manipulated, so a safe automatic closing of the door cannot be guaranteed, which is a special inconvenience in case of using fire doors.

Each time the door is opened, the entire spring mechanism of the locking mechanism must be prestressed with greater effort. All moving parts of the lock are loaded each time the door is operated, so they are exposed to increased wear and must be sized accordingly. The psychological effect is also added: as a rule, the door closing process is separated from the interlocking process, while a single process takes place in the device described here. Since the interlocking of the lock cannot be detected from the outside, the user does not know exactly the actual interlocking state of the door.

Also in EP 1 032 743 B1 an automatic interlocking lock is described, with a spring loaded trigger, a spring loaded latch and a spring loaded auxiliary trigger, which retains a mobile slider in the longitudinal direction of the lock when The latch is in the rear position, the slider being prestressed by closing the spring loaded latch and releasing the lock latch when closing the auxiliary trigger and the time-delayed trigger. The pretension of the slider is carried out both by means of teeth of the cylinder and of the key, and by means of a lever of rotary operation by means of a nut. Also in this device a simultaneous trigger lock and a door interlock is performed.

Document FR 2 663 073 A1 discloses a device for actuating a panic lock. Here there is a first element, formed by a spring, which is loaded with elastic energy as the latch advances and which is in a functional relationship with a lock latch and a second element is provided, which is formed by a movable hook in the vertical direction for interlocking as well as for unlocking for outgoing and removed positions of the latch. The skewer carries a protrusion, which rests in the lower or interlocked position of the skewer at the end of a tongue of a nut, in which the lock actuation handle is fixed. By turning the nut in the opening direction, the tongue moves the projection from the bottom up and thus causes the skewer to be raised to its upper unlocking position, in which the latch is completely withdrawn, this withdrawal movement being activated by the release of the elastic energy that has accumulated in the spring in the closing movement of the latch.

EP 1 617 018 A2 describes an electromechanical lock of a door, with a door lock housing, with a locking latch, which can be locked in the door lock housing in an outgoing position and which can be removed by an electric drive device inside the door lock housing, with a spring loaded trigger for centering the latch in its locked position in an opening of a deflector plate, the trigger having a moving centerpiece inside of the door lock housing and a wedge-shaped part, which is at least partly in an outgoing position of the door lock housing in the outgoing position of the trigger. The wedge-shaped part is attached to the central part to allow a rotating movement of the wedge-shaped part with respect to the central part, so that the trigger can be pressed into the door lock housing, when, on either side of the door lock housing, a force acts in the direction of the opening or closing of a door provided with the door lock on the wedge-shaped part, being provided

first transmission elements for the transmission of the force of the electric drive device to the latch, with a first locking device for locking the trigger in its outgoing position, while the latch is in the interlocking position and with a second locking device for the latch in its interlocking position, the latch being able to be placed at the time of unlocking and by removing it inside the door lock housing in a functional connection with second transmission elements to cancel the trigger lock.

Therefore, the objective of the present invention is to carry out a panic lock that avoids the indicated inconveniences, in particular to create a panic lock in which the user has the security of having locked the lock. In addition, the lock should have a simple structure, the closing mechanics being exposed inside the lock housing at reduced solicitations, to avoid great wear, so that the life of the panic lock can be substantially increased.

To achieve this objective, a panic lock with the features of claim 1 is proposed. Preferred variants are made in the dependent claims.

According to the invention, it is provided that a retention unit, which is arranged at a distance from the slider, is assigned to the latch, which keeps the latch in its second position, that the slider is spring loaded and automatically moves from the second position of return to the first position and that in the second position of the latch the closing cylinder releases the retention unit in a rotating position, whereby the latch moves to its first position, the slider being retained in its first position.

According to the invention, a panic lock with a semi-automatic displacement of the latch is proposed. Trigger locking or unlocking is done here by the slider, which also moves the latch from the first position to the second and vice versa. It is especially advantageous that the slider always adopts its first position after operation, in particular the lower position. The preferably prestressed latch is retained by the retention unit and is therefore in a kind of waiting position. This self-locking mechanism can be released by the closing cylinder, for example by a 90 ° rotation of the cylinder, whereby the latch passes to its first protruding position. The displacement of the latch, that is, the movement of the latch from its second position to the first position, is not performed automatically, that is, not automatically with the release of the trigger but is initiated separately by the closing cylinder (mechanism Semiautomatic). It is especially advantageous for the user to have the security of having locked the panic lock thanks to the closing actuation separated from the closing cylinder. Another advantage of this invention is that not all moving parts are loaded inside the lock housing each time the door is operated. In particular, in sliding the latch the slider remains in its first position, so that in addition to reduced wear of the lock, noise generation can also be kept low.

In an advantageous embodiment of the invention, the retention unit is spring loaded and can be moved to a first and a second position, the movement of the retention unit being preferably a translational movement. In the first position of the retention unit, the latch is retained in its second unlocked position. In a preferable embodiment, the latch is made with an interlocking means and the retention unit with a complementary interlocking means. In the first position of the retention unit and in the second position of the latch, the interlocking means and the complementary interlocking means fit into each other, the bolt preferably pressing in this position a force accumulator, in particular a spring. This claim advantageously serves the automatic displacement of the latch, when the retention unit is moved to its second position.

In another possible embodiment of the invention, the latch has a slide guide and the latch has a pin, which is necessarily guided in the slide guide. Advantageously, the slide guide has several interlocking points. In a preferable embodiment, in the first position of the latch the pin is in a first interlocking point, in the first position of the slider and in the second position of the latch the spike is in a third interlocking point and in the second position of the slider and in the second position of the latch the pin is in a second interlocking point.

Depending on the door drive, the slider moves, the latch being fixed at the same time or vice versa. At the same time, the spindle travels along the slide guide.

It is recommended that the slider has a second spring loaded locking element, which is rotatably housed around an axis and that extends at least in part in the slide guide. In a preferable embodiment of the panic lock, during the movement of the latch from its second to the first position, the pin can move from the third interlocking point to the first interlocking point. While the spike moves along the slide guide of the slider, there is a contact between the spike and the second locking element that looks out of the slide guide. Another movement of the pin in the direction of the first interlocking point causes the second locking element to exit the slide guide by rotating about its axis. The free end of the second locking element, not oriented towards the shaft, advantageously ends in front of the first locking point of the slide guide. After having moved the

pin along the second locking element and having reached the first interlocking point, the second spring-loaded locking element automatically rotates backwards and looks out at least with a part inside the slide guide, so that effectively prevents a shift of the latch backwards leaving the locked position. The slide guide as well as the second locking element form a two-way control for the interlocking process.

In another advantageous configuration of the panic lock, a lever is arranged inside the lock housing, which is rotatably housed around a drive shaft, in which a drive element, in particular a rotary knob, can be fixed , a handle or the like. Advantageously, the slider has a drag stop, by turning the lever around the drive shaft in one drive of the drive element and moving the drag stop with its free end, whereby the slider can be passed from its first to Your second position. In this way a panic function of the lock according to the invention is carried out, in which the panic lock can be opened in the closed state of the lock from the inside by means of a corresponding actuation of the drive element. While the lever guides the slider by the drag stop from its first position to the second position, the pin moves along the slide guide of the slider.

A measure that improves the invention can provide that the first blocking element is housed around a rotation axis and is made with a projection, the trigger being held and immobilized on the projection in the blocking position. Advantageously, a spring loaded auxiliary trigger is provided, which protrudes from the lock housing, which is in a functional connection with the first locking element.

It is especially advantageous that the trigger is made as a cross trigger, so that a possibility of use to the right and left of the panic lock can be achieved. In an alternative embodiment, instead of a cross trigger, a rolling trigger can be used, which is advantageous, in particular, in the case of swinging doors. Furthermore, it has been shown that to reduce noise, the use of damping means, which cooperate with the trigger and / or the latch, can be advantageous.

In another embodiment of the invention a display system may be provided, which visualizes and / or assesses the position of the latch in an optical and / or acoustic and / or electrical manner. A lock of this type can have a data communication, for example with an access control system, which can be advantageous, for example, in the hotel area.

Other advantages, features and details of the invention result from the description set forth below, in which several embodiments of the invention have been described in detail, with reference to the drawings. The features mentioned in the claims and in the description can be essential for the invention respectively separately or in any combination.

Figure 18 a possible embodiment of a locking element that is arranged in the slider.

A panic lock showing a lock housing 1, in which Figure 1 is shown, is shown in Figure 17.

25 is provided a latch 2, which locks in a first position that protrudes from the lock housing 1, which is represented for example in Figure 7. In addition, the latch 2 can be removed to a second position unlocked inside the housing of lock 1, which is represented for example in Figure 1. In addition, the panic lock according to Figure 1 to Figure 17 has a trigger 3, which can be passed through a first locking element 4 to a locked position already An unlocked position. In the present example of

30 realization is about a cross trigger 3.

Inside the lock housing 1 there is arranged a slider 10, which can move in a translational movement to a first position and a second position. The slider 10 has a slider end 11, which is oriented towards the first locking element 4.

35 The slider 10 has a slide guide 15 and the latch 2 a pin 16, which is necessarily guided in the slide guide 15. Thanks to the vertical and horizontal movement of the latch 2 and the slider 10, the pin 16 can take any position. inside the slide guide 15. As can be seen according to Figure 1, the slide guide 15 has approximately the outline of a triangle. Through this slide guide 15, the

40 slider 10 is in a functional connection with the latch 2, so that in the first locked position of the latch 2, during the movement from the first position to the second position, the slider 10 passes the latch 2 to the second position, what will be described in more detail below.

In addition, a retention unit 12 is provided, which is arranged at a distance from the slider 10. The

Retention 12 is assigned to latch 2 and retains latch 2 reliably in its second position. As shown in Figure 1, the retention unit 12 is spring loaded. The latch 2 is in accordance with Figure 1 in its second position unlocked inside the lock housing 1. Here, the latch 2 has a projection 14 as a heel, which is retained in the retention unit 12.

50 The slide guide 15 of the slider 10 is made with three locking points 15a, 15b, 15c. In addition, the slider 10 has a second spring loaded locking element 26, which is rotatably housed around an axis 17 and which extends at least in part in the slide guide 15.

To guarantee the panic function, the present panic lock has inside the housing of

1 lock 1 a lever 19, which is rotatably housed around a drive shaft 18, in which a drive element, in particular a rotary knob, a handle or the like, can be fixed. The slider 10 has a drag stop 20, in which it attacks the lever 19 with its free end.

The first locking element 4 is housed around an axis of rotation 21 and has a projection 22, being

60 held and immobilized the trigger 3 on the projection 22 in the locked position, which is shown in Figure 4 by way of example. According to Figure 1, the trigger 3 is in the unlocked position, the projection 22 having a sufficient distance from the trigger 3. In addition, an auxiliary trigger 23 is disposed above the trigger 3 protruding spring loaded from the lock housing. 1. As can be seen in the Figures, the auxiliary trigger 23 is in a functional connection with the first blocking element 4. Here, the first blocking element 4 is

65 made with an inner guide zone 24, in which a pin 25 arranged in the auxiliary trigger 23 is guided.

According to Figure 1 to Figure 4, the process of closing the door in which the panic lock is arranged is represented. In Figure 1, the door is in the open position, the latch 2 being in a self-locking situation, that is to say in its second unlocked position inside the lock housing 1. The trigger 3 is in its unlocked position, the auxiliary trigger 23, as well as the trigger 3 being deployed. In Figure 2, the door closes, the trigger 3 being inserted as well as the auxiliary trigger 23 under pressure inside the lock housing 1, which is shown by the Arrows pointing to the right. At the same time, the pin 25 moves along the inner guide zone 24, turning the first locking element 4 counterclockwise around the axis of rotation 21. At the same time, the trigger 3 it moves with the area oriented towards the first blocking element 4, below the protrusion 22, which in the embodiment described below is carried out in a staggered manner.

The state of the closed door is shown in Figure 4, in which the trigger 3 exits the opening of the door strike 27, which is represented by the arrow. At the same time, a rotation of the first locking element 4 is made counterclockwise around the axis of rotation 21. This lowers the first locking element 4, fitting the projection 22 behind the trigger 3 and locking it. in this way.

In Figure 4, the panic lock according to the invention is therefore in a locked and not locked state. To now lock the door, the closing cylinder 13 is turned counterclockwise. Here, the closing cylinder 1 has an activation projection 28, which raises the retention unit 12 according to Figure 5, until the retention unit 12 no longer holds the projection of the latch 2 in position. Next, latch 2 exits its second position towards the first position. Therefore, the latch 2 moves to the left, which is caused by the spring 28, which presses with its free end directly on the latch 2 with a determined spring force.

The movement of the latch 2 to the locking state is further shown in Figure 6 and Figure 7. Here, the pin 16 moves along the slide guide 15 of the slider 10. The slide guide 15 is made here with a first interlocking point 15a, a second 15b and a third interlocking point 15c. Starting from the third locking point 15c, the pin 16 moves in the horizontal direction along the slide guide 15 to the first locking point 15a. As shown in Figure 6, a contact is established between the pin 16 and the second locking element 26 made as a lever. While the pin 16 moves in the horizontal direction towards the first locking point 15a along the slide guide 15, it releases the second locking element 26 under pressure from the slide guide 15 in the direction of the needles of the clock around the axis of rotation 17. After having reached the pin 16 the first locking point 15a, which is shown in Figure 7, the second locking element 26 lowers counterclockwise back to its initial position, extending with its free end at least in part on the slide guide 15. In this position of the second locking element 26, the latch 2 is prevented from pushing back to its second position. The closing cylinder 13 with its activation projection 28 is according to Figure 7 below again in its initial position. It is especially advantageous that the interlocking process just described is carried out substantially by the movement of the latch 2, as well as the second locking element 26, without moving the latch 10 from its first lower position. Figure 7 shows the panic lock in the locked and locked state.

Starting from Figure 7, it is only shown how the panic lock according to the invention can be unlocked and unlocked by means of the closing cylinder 13, so that a door opening is possible. According to Figure 8, the closing cylinder 13 is rotated clockwise, the activation projection 28 coming into contact with a stop 30 as a projection of the slider 10. In this way a linear movement of the slider 10 upwards, in the direction of the first locking element 4. At the same time, the pin 16 leaves the first locking point 15a. While the pin 16 slides along the inclined wall of the slide guide 15, which is located between the first locking point 15a and the second 15b, the latch 2 is entered by the sliding guide 15 to the right to the second non-locked position, at the same time approaching the end of the slider 11 of the slider 10 to the first locking element 4. Shortly before the latch 2 is found in the final entry position, that is, being retained by the retention unit 12, the first locking element 4 is lifted from the end of the slider 11 and unlocks the trigger 3, which is shown in Figure 10. While the latch 2 is moved from the first position to the second position, at the same time the latch spring 29 is pre-tensioned. According to Figure 11, the trigger 3 is unlocked and the door can be opened. According to Figure 11, the unlocked trigger 3 can be pressed back into the lock housing 1 with the opening movement of the door. In Figure 12, the trigger 3 returns from the lock housing 1 to the left and the closing cylinder 13 can turn back to its initial position. The slider 10 exits here from its second position according to Figure 11 and moves back again to its first lower position, shown in Figure 12. Here, the pin 16 passes from the second interlock point 15b to the third interlock point 15c

According to Figure 13 to Figure 17, the door opening process is carried out in the case of the present panic lock by means of the lever 19. The user activates the drive element, which is not explicitly represented. The drive element is arranged on the drive shaft 18. The lever 19 moves around the drive shaft 18 clockwise, moving the free end of the

lever 19 the drag stop 20 up. This results in a translational movement of the slider 10 from its first lower position in the direction of the second position, which is provided for the release of the trigger 3, which is shown in Figure 16. While the lever 19, which presses against a spring 32, rotates around its drive shaft 18, the pin 16 moves along the slide guide 15 of the first locking point 15a in the direction of the second locking point 15b. Thanks to this forced guidance, the latch 2 is removed from its first position in the direction of the lock housing 1 to the second unlocked position. At the same time, the end of the slider 11 moves in the direction of the projection 22 of the first blocking element 4, which locks in Figure 13 and in Figure 14 the trigger 3. According to Figure 15, the inlet of the latch stops , since the pin 16 enters the second locking point 15b, which is made as a kind of bag arranged in the vertical direction. At the same time, the projection 14 of the latch 2 fits into the retaining unit 12, whereby the latch 2 arrives in a self-locking state and thus passes to its second position. As can also be seen according to Figure 15, the end of the slider 11 unlocks the trigger 3, coming into contact with the projection 22 and at the same time raising the first locking element 4 and turning clockwise around its axis 21. Now the door can be opened, since it is unlocked and unlocked. According to Figure 16, the user now acts on the drive element, so that the lever 19 is held in position. At the same time the door can be moved, turning the unlocked trigger 3 spring loaded to the lock housing 1, which is indicated by the arrow pointing to the right.

In Figure 17, the panic lock is shown with the door open, the trigger 3 of the lock housing 1 having exited. The unloaded lever 19 has been rotated by the spring 31 to its initial position. Due to the spring 32 acting on the drag stop there is a movement of the slider 10 from its second position to its first position. At this time, the pin 16 has left the second locking point 15b and has reached the third locking point 15c. In the unlocked position of the trigger 3, the auxiliary trigger 23 protrudes from the lock housing 1, which is caused by the spring 33.

Another embodiment of the second locking element 26 is shown in Figure 18, which is made with locking points 26a, 26b. Here, the locking points 26a, 26b are arranged on the side facing the slide guide 15 of the second locking element 26, which narrows in the direction of the first locking point 15a of the sliding guide 15 of the slider 10. While that the latch 2 moves from its second position to the first position, the pin 16 slides along the second locking element 26, pressing firstly at the first interlocking point 26a and then at the second interlocking point 26b. It has been shown that thanks to such an embodiment, the panic lock switching mechanism is exposed to minor solicitations.
