Description

The invention relates to a panic lock with a lock cylinder, a lock housing, in which a latch is arranged, which is locked in a first, protruding from the lock housing position and retractable into a second, unlocked position in the lock housing, a case consisting of the lock housing projecting and can be brought via a first blocking element in a blocking position and in an unlocked position, a slider which is translationally movable within the lock housing in a first and in a second position and having a slider end, in the second position of the slider, the first blocking element contacted and lifted the locking position of the case, the slider is in operative connection with the bolt, that in the locked first position of the bolt during movement from the first position to the second position, the slide brings the bolt in the second position.

In the DE 39 38 655 C2 is a self-locking lock is described, which brings with the aid of a biased slide after its release both a bolt in a locked position, as well as a cross latch locks. In the reverse direction, the slider can be moved back both by a door handle and by a lock cylinder, whereby the lock is unlocked. In this case, the locking position of the cross latch and bolt is automatically initiated when the cross latch and a designated auxiliary latch are operated in a logical sequence that corresponds to the closed position of the door. Essential in this embodiment of the lock is the means of tax trap in self-holding slide. One of the disadvantages of this disclosed lock is that at each door closing next to the locking of the cross latch also preclose the bolt takes place. This is usually significant noise on. Furthermore, the switching logic of auxiliary and cross latch can also be manipulated, whereby, for example, a secure self-closing of the door can not be guaranteed, which is a particular disadvantage when used on fire doors.

At each door opening, the entire spring mechanism of the lock mechanism of the lock must be biased with increased effort. All moving parts of the lock are loaded with each door operation and are therefore subject to increased wear and must be dimensioned accordingly. Furthermore, the following psychological effect is added: In general, the process of door closing is separate from the process of locking, while the device described here is a single process. Since it is not possible to detect the locking of the lock from the outside, the user remains unclear about the actual locking status of the door.

Also in the EP 1 032 743 B1 describes a self-locking lock with a spring-loaded latch, a spring-loaded latch and a spring-loaded auxiliary latch which locks a slide movable in the longitudinal direction of the lock with locked latch, the slide is biased spring-loaded when locking the latch and temporally when enclosing the auxiliary latch and the case Delays the latch releases from lock. The bias of the slider is effected both by means of a cylinder and key bit as well as by means of a pivotable by means of a nut actuating lever. Also in this device, a simultaneous locking of the trap and locking the door.

It is therefore an object of the present invention to form a panic lock, which avoids the disadvantages mentioned, in particular that a panic lock is created in which the user has the assurance that he has locked the lock. Furthermore, the lock should have a have simple structure, wherein the locking mechanism is exposed within the lock housing low loads to avoid high wear, whereby the life of the panic lock can be significantly increased.

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

According to the invention, it is provided that a holding unit, which is arranged at a distance from the slide, is associated with the latch, which holds the latch in its second position, the slide is spring-loaded and moves independently from the second position back to the first position, and in the second Position of the bolt of the lock cylinder in a rotational position, the holding unit triggers, whereby the bolt moves to its first position, wherein the slider is held in its first position.

According to the invention a panic lock with a semi-automatic bar exclusion is proposed. The locking and unlocking of the case takes place here by means of the slide, which also leads the bolt from the first to the second position and vice versa. It is particularly advantageous that the slide always takes its first position, in particular the lower position, after its actuation. The preferably biased latch is held by the holding unit and is thus in a kind of waiting position. This self-holding mechanism can be solved by the lock cylinder, for example by a 90 ° cylinder rotation, whereby the bolt moves to its first, projecting position. The bolt exclusion, that is, the movement of the bolt from its second position to the first position, does not occur automatically, that does not mean automatically with the Fallenentsperrung, but is introduced separately via the lock cylinder (semi-automatic). It is particularly advantageous that the user by the separate closing operation of the lock cylinder the certainty gets to have locked the panic lock. Another advantage of this invention is that with each door operation not all moving within the lock housing parts are charged. In particular, the bolt exclusion of the slider remains in its first position, which in addition to a low wear of the castle and the noise can be kept low.

In an advantageous embodiment of the invention, the holding unit is spring loaded and movable in a first and in a second position, wherein it may be in the movement of the holding unit preferably a translational movement.

a possible embodiment of a blocking element which is arranged on the slider.

In Fig. 1 to Fig. 17 a panic lock is shown, which has a lock housing 1, in which a bolt 2 is arranged, which locks in a first protruding from the lock housing 1 position, which, for example, in Fig. 7 is shown. Furthermore, the latch 2 is retractable into a second, unlocked position in the lock housing 1, which, for example, in Fig. 1 is shown. Furthermore, the panic lock according to the Fig. 1 to Fig. 17 a case 3, which can be brought via a first blocking element 4 in a blocking position and in an unlocked position. In the present embodiment, it is a cross latch. 3

Within the lock housing 1, a slide 10 is arranged, which is translationally movable in a first and in a second position. In this case, the slider 10 has a slider end 11, which faces the first locking element 4.

The slider 10 has a slotted guide 15 and the bolt 2 a pin 16 which is forcibly guided in the slotted guide 15. Due to the vertical and horizontal movement of bolt 2 and slider 10, the pin 16 can take any position within the slide guide 15. As per Fig. 1 can be seen, the slide guide 15 has approximately the contour of a triangle. About this slide guide 15, the slider 10 is in operative connection with the bolt 2, that in the locked first position of the bolt 2 during movement from the first position to the second position of the slider 10 brings the latch 2 in the second position, hereinafter referred to will be discussed in detail.

Furthermore, a holding unit 12 is provided which is arranged at a distance from the slider 10. The holding unit 12 is associated with the latch 2, which reliably holds the latch 2 in its second position. As per Fig. 1 is clarified, the holding unit 12 is spring-loaded. The latch 2 is located according to Fig. 1 in its second, unlocked position within of the lock housing 1. Here, the latch 2 has a nose-like projection 14, which is held in the holding unit 12.

The slide guide 15 of the slider 10 is designed with three locking points 15a, 15b, 15c. In addition, the slider 10 has a second, spring-loaded locking element 26 which is rotatably mounted about an axis 17 and at least partially extends into the slotted guide 15.

In order to ensure the panic function, the present panic lock within the lock housing 1 on a lever 19 which is rotatably mounted about an actuating axis 18, in which an actuator, in particular a knob, handle or the like can be fastened. The slider 10 has a driver 20, on which the lever 19 engages with its free end.

The first locking element 4 is mounted about an axis of rotation 21 and has a projection 22, wherein in the blocking position, the latch 3 is held on the projection 22 holding, which in Fig. 4 is shown by way of example. According to Fig. 1 is the latch 3 in the unlocked position, wherein the projection 22 has a sufficient distance from the case 3. In addition, an auxiliary latch 23 is arranged above the latch 3, which protrudes spring-loaded out of the lock housing 1. As can be seen in the figures, the auxiliary latch 23 is in operative connection with the first blocking element 4. Here, the first locking element 4 is formed with an inner guide portion 24 in which a arranged on the auxiliary latch 23 pin 25 is guided.

According to the Fig. 1 to Fig. 4 is the closing of the door in which the panic lock is arranged, shown. In Fig. 1 the door is in the open position, wherein the latch 2 is in latching, that is, in its second, unlocked position within the lock housing 1 is located. The latch 3 is in its unlocked position, with the auxiliary latch 23 and the latch 3 extended. In Fig. 2 close the door, wherein the latch 3 and the auxiliary latch 23 are pressed into the lock housing 1, which is indicated by the arrows pointing to the right. At the same time, the pin 25 moves along the inner guide portion 24, wherein the first locking member 4 pivots counterclockwise about the rotation axis 21. At the same time, the latch 3 moves with the area facing the first blocking element 4, below the projection 22, which in the following embodiment is designed in steps.

In Fig. 4 the state of the closed door is shown, in which the latch 3 extends into the opening of the strike plate 27 of the door, which is shown by the arrow. At the same time, a rotation of the first locking element 4 takes place counterclockwise about the axis of rotation 21. As a result, the first locking element 4 lowers, wherein the projection 22 engages behind the case 3 and thus locks them.

In Fig. 4 Thus, the panic lock according to the invention is in a locked and unlocked state. Now to lock the door, the lock cylinder 13 is rotated counterclockwise. Here, the lock cylinder 13 on an activation projection 28, according to Fig. 5 the holding unit 12 lifts until the projection of the bolt 2 is no longer held by the holding unit 12 in its position. Subsequently, the bolt 2 moves from its second position in the direction of the first position. Thus, the bolt 2 shifts to the left, which is effected by means of the spring 29, which presses with its free end directly on the bolt 2 with a certain spring force.

The movement of the bolt 2 in the locking state is further in Fig. 6 and Fig. 7 clarified. Here, the pin 16 moves along the sliding guide 15 of the slider 10. The slide guide 15 is in this case formed with a first 15a, with a second 15b and a third latching point 15c. Starting from the third stop 15 c moves the Pin 16 horizontally along the slide guide 15 to the first latching point 15a. As Fig. 6 While the pin 16 moves horizontally in the direction of the first latching point 15a along the slotted guide 15, it pushes the second locking element 26 from the slotted guide 15 in a clockwise direction about the axis of rotation 17th out. After the pin 16 has reached the first latching point 15a, which in Fig. 7 is shown, the second locking element 26 lowers counterclockwise back to its original position, wherein it at least partially extends with its free end in the slotted guide 15 itself. In this position, the second locking element 26, a pushing back of the bolt 2 is prevented in its second position. The lock cylinder 13 with its activation projection 28 is located according to Fig. 7 then again in its original position. It is particularly advantageous that the locking process just described essentially by the movement of the bolt 2 and the second locking element 26 takes place without moving the slider 10 from its first, lower position. Fig. 7 illustrates the panic lock in the locked and locked state.

Starting from Fig. 7 only shows how the panic lock according to the invention can be unlocked and unlocked by means of the lock cylinder 13, whereby a door opening is made possible. According to Fig. 8 the lock cylinder 13 is rotated clockwise, wherein the activation projection 28 comes into contact with a projection-like stop 30 of the slider 10. This results in 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 latching point 15a. While the pin 16 along the oblique wall of the slotted guide 15, which is located between the first 15a and the second latching point 15b slides along, the bolt 2 is fed via the slotted guide 15 to the right, in the unlocked second position, at the same time the slider end 11 of the slider 10 approaches the first blocking element 4. Just before the bar 2 is in the feed end position, that is held by the holding unit 12, the first locking element 4 is raised by the slider end 11 and unlocks the case 3, which in Fig. 10 is shown. While the latch 2 is guided from the first position to the second position, the latch spring 29 is simultaneously biased. According to Fig. 11 the latch 3 is unlocked and the door can be opened. According to Fig. 11 the unlocked latch 3 can be pushed back into the lock housing 1 with the door opening movement. In Fig. 12 leaves the case 3 again the lock housing 1 to the left and the lock cylinder 13 can be rotated back to its original position. The slider 10 leaves in this case according to its second position Fig. 11 and moves back to its lower first position, which is in Fig. 12 is clarified. Here, the pin 16 moves from the second stop 15b in the third stop 15c.

According to FIGS. 13 to 17 the door opening operation is effected in the present panic lock on the lever 19. The user activates the actuator, which is not explicitly shown. The actuator is arranged in the actuation axis 18. The lever 19 moves about the actuating axis 18 in a clockwise direction, wherein the free end of the lever 19 moves the driver 20 upwards. 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 unlocking the case 3, which in Fig. 16 is shown. While the lever 19, which presses against a spring 32, rotates about its actuating axis 18, the pin 16 moves along the slotted guide 15 from the first latching point 15a in the direction of the second latching point 15b. By this forced operation of the bolt 2 is withdrawn from its first position in the direction of the lock housing 1 in the second, unlocked position. At the same time the slider end 11 moves in the direction of the projection 22 of the first blocking element 4, which in the Fig. 13 and Fig. 14 the trap 3 locks. According to Fig. 15 comes the locking mechanism to a halt, because the pin 16 in the second latching point 15b, which is designed as a kind of vertical bag moves. At the same time, the projection 14 of the bolt 2 engages in the holding unit 12, whereby the bolt 2 in a. Self-latching arrives and is thus brought into its second position. As per Fig. 15 can be seen, unlocks the slider end 11, the case 3, in which it contacts the projection 22 and at the same time lifts the first locking element 4 and rotates about its axis 21 in a clockwise direction. The door can now be opened as it is unlocked and unlocked. According to Fig. 16 the user still acts on the actuator, so that the lever 19 is held in its position. At the same time, the door can be moved, wherein the unlocked latch 3 spring-back moves back into the lock housing 1, which is indicated by the arrow pointing to the right.

In Fig. 17 the panic lock is shown with the door open, in which the case 3 has left the lock housing 1. The unloaded lever 19 has been rotated by the spring 31 in its original position. Due to the force acting on the driver 20 spring 32 was a movement of the slider 10 from its second to its first position. In this case, the pin 16 has left the second latching point 15b and reaches the third latching point 15c. In the unlocked position of the case 3, the auxiliary latch 23 projects out of the lock housing 1, which is caused by the spring 33.

In Fig. 18 a further embodiment of the second blocking element 26 is shown, which is carried out with latching points 26a, 26b. Here, the latching points 26a, 26b are arranged on the slide guide 15 facing side of the second locking element 26, which tapers in the direction of the first latching point 15a of the slide guide 15 of the slider 10. While the bolt 2 moves from its second to the first position, the pin 16 slides on the second blocking element 26, wherein it is first pressed into the first latching point 26a and then into the second latching point 26b. It has been shown that by such an embodiment the switching mechanism of the panic lock is exposed to lower loads.
