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. Further, the slider has a contacting surface on which acts a power transmission member which is driven by an electric motor. Disadvantageously, this lock has a complex and complicated structure. Furthermore, for the locking and unlocking always the electric motor to activate to move the central slide in its corresponding position, which disadvantageously considerable noise. Furthermore, the electrical actuator is exposed to increased wear at each door operation and must be sized accordingly.

It Therefore, the object of the present invention is a panic lock form, which avoids the disadvantages mentioned, in particular that a panic lock is created, which is a simple structure has, with the locking mechanism inside the lock housing low stress is exposed to high wear avoid, thereby reducing the life of the panic lock essential can be increased.

to The solution to this problem is a panic lock with the features of claim 1 proposed. In the dependent claims preferred developments are executed.

According to the invention provided that a holding unit, which is spaced from the slider is arranged, is associated with the bolt, the bolt in his second position holds, and a second electrical actuator engages the holding unit such that in the second position of the The second electric actuator locks the holding unit which causes the bolt to move to its first position, wherein the first actuating device is deactivated.

The holding unit causes the latch, which is in the unlocked second position, a latch. In the electrically controlled locking of the panic lock, the second electrical actuator is activated, which acts directly on the holding unit, whereby it dissolves and the bolt on which a corresponding spring force acts, moves independently in its first position. Preferably, the second electrical actuator is driven with a trigger signal for the locking operation, which briefly triggers the holding unit and the bolt automatically moves via the spring force to its first position. Subsequently, the second electrical actuator is in a deactivated state. The triggering signal may also be a pulsed signal. Advantageously, the lock mechanism in the described locking process - compared to the cited prior art DE 39 38 655 C2 - Less stressed, which in addition to a low wear of the panic lock and the noise can be kept low.

advantageously, the holding unit is spring loaded and in a first and in a movable second position, wherein in the first position of the bolt in its second Position is held. In a preferred embodiment is the latch with a locking means and the holding unit with a Counter-locking means running. In the first position of the holding unit and in the second position of the latch grip means as well Gegenrastmittel into each other, preferably in this position the bolt a force accumulator, in particular a spring, biases. This bias is used for the automatic bar exclusion, if the holding unit is guided in its second position.

In one possible embodiment of the panic lock, the holding unit has an axis of rotation about which the holding unit can be pivoted into the first and the second position. The holding unit can be designed, for example, L-shaped, which has a first and a second leg, wherein the second actuating device acts at a distance from the axis of rotation on the first leg and a spring is arranged at a distance from the axis of rotation on the second leg. In this case, even a small force starting from the second actuating device is sufficient, which is at a distance from the axis of rotation of the holding unit on the leg acts to release the holding unit from the bolt, which then automatically moves to its first position.

Conveniently, the slider has a first slide guide and the bolt a pin, which is forcibly guided in the first link guide. During the movement of the slider from the first into the second position and / or the movement of the bolt from its first Position in the second position and vice versa, a shutdown takes place of the pin along the first link guide. Here can the slide guide have different geometries. In a possible embodiment of the invention For example, the first slide guide is approximately a linear one Contour on, which is at an angle to the linear direction of movement of the bolt, wherein the angle is between 20 ° ≤ α ≤ 70 °. Preferably, the first slotted guide is at both of them End areas each with a rest stop for the pin executed.

alternative For this purpose, the first link guide in about a trapezoidal Contour, wherein the first link guide with several Rest stops is formed. In the first position of the bolt The pin can be in a first stop. In the first position of the slider and in the second position of the bolt the pin can be located in a third rest stop. In the second position of the slider and in the second position of the bolt the pin can be positioned in a second rest stop. Of the Spigot moves here the first link guide in a clockwise or counterclockwise direction, where depending on the locked state of the lock Pin is fixed in the respective mentioned rest stop.

advantageously, is the power transmission member is a drive wheel to an axis is rotatably mounted and a projection-like pin at a distance from the axis, with the contacting surface interacts. In the first position of the slide has the pin a distance to the contacting surface and during the drive wheel through the first actuator is driven, the pin contacts the contact surface and thus guides the slider in the second position.

The Drive wheel may be formed, for example, as a cam wheel. For motor actuation, the inventive Panic lock an electric motor as the first actuator is executed, the cam wheel via a worm wheel drives, whose rotation about the axis of the cam wheel translational Movement of the slider causes.

A the measure improving the invention provides that within of the lock housing, a lever is arranged around a Actuating axis into which an actuator, in particular a knob, handle or the like fastened is rotatably mounted. Advantageously, the slider a driver, wherein upon actuation of the actuator the lever turns around the actuation axis and with his free end moves the contacting surface of the driver, thereby the slider can be moved from its first to its second position is. As a result, a panic function of the invention Castle realized in the locked state of the castle the panic lock from the inside by a corresponding operation of the actuator can be opened. While the lever over the driver the slider from its first leads to the second position, the pin moves along the first slide guide of the slider.

Further can be provided that the lever for manual Actuation is provided, at the same time as a power transmission member for the electrically controlled locking acts. in this connection the lever is driven by the first actuator.

The first and / or the second actuator can designed as an electric motor and / or as a solenoid be. The electromagnetic control via the lifting magnet can be used both on the open-circuit principle and on the closed-circuit principle respectively. The inversion of the effective electrical direction is through easy conversion from outside is also possible. The bolt release by means of lifting magnets can with small magnetic forces be realized, especially when the magnetic voltage intermittently is, comparable to a door opener.

In a preferred embodiment of the invention is a spring loaded latch protruding from the lock housing, intended. In this case, the trap may have a within the Lock housing arranged locking member in a locking position and placed in an unlocked position. The trap can be interpreted as a cross-trap, whereby a legal and Linksverwendbarkeit the panic lock can be achieved. In an alternative embodiment, instead of a cross latch one Roll trap (without tax trap) are used, which in particular is beneficial for swing doors. Furthermore, it has become demonstrated that, for noise reduction, the use of damping means, which cooperate with the trap and / or the bolt, advantage can be.

Furthermore, a display system can be provided which visually and / or acoustically and / or electrically displays and / or evaluates the position of the bolt. Such a lock can, for example with an access control system in data communication, which may be advantageous for example in the hotel sector.

When Advantageously, it has been proven that the slide with a second Slotted guide, which has three locking points executed is, in which a pin of the trap is forced. in this connection the latch is extended when the pin is at the first stop located. The trap is also retracted inside the lock housing, when the pin is in the second and / or third rest stop located. Advantageously, the first slotted guide adapted to the second slide guide, that means that too the first slide guide has three locking points.

Preferably is the first link guide with three rest stops in such a way executed that the holding unit in the second position befindlichem latch releases, causing the latch in his first position moves and at the same time from the third stop in the first resting place of the first slide guide itself emotional. The movement of the pin along the first link guide starting from the third rest stop to the first rest stop in the same direction as the movement of the bolt of his second position in his first position. Especially advantageous is that the slider remains in its first position. The preferably biased latch is through the holding unit held and is a kind of waiting position. This self-holding mechanism is for example via the second electrical actuator solved, causing the latch in his first, protruding Position moves. The bar exclusion, that is the movement of the bolt from its second position to the first Position, does not take place independently, that does not mean automatically with the case unlocking, but is separated over the introduced second actuator. In particular not moved for the locking process, the slider must be, is a low-wear lock mechanics with achieved a low noise.

In a possible embodiment of the invention the slider on a spring-loaded locking element, which is rotatable is mounted about an axis and at least partially in the first Slotted link extends. Preferably moves - while the movement of the bolt from its second to the first position - the Pin from the third stop in the first stop. While the pin along the first slide guide of the slider moves, it comes to a contact between the pin and the protruding into the first link guide blocking element. Another movement of the pin in the direction of the first stop causes the blocking element from the first link guide is moved out of its axis. After the pin along the Locking element has moved and reached the first stop has, pivots the spring-loaded locking element automatically back and sticks out with at least one area in the first Sliding guide into it, whereby a pushing back the bolt is effectively prevented from the locked position. The first link guide and the blocking element form a 2-way control for the bolt sequence.

In an alternative embodiment of the panic lock are the first and the second slide tour with a short and a formed parallel to the long edge, which is perpendicular to the Direction of movement of the latch and the bolt are aligned. in this connection has the short edge of the second link guide a greater distance than the short flank of the first Slotted guide, creating a separate latch stroke and deadlift can be achieved. While the slide out of his first Position is moved to the second position, the pin slides the trap of the first stop from initially along the short flank. At the same time moves the pin of the bolt from the first rest stop along the short flank towards the second rest stop. The short flank of the first link guide closes a sloping wall in the direction of the second rest stop. While the slider is moved to the second position, leaves the pin the short flank of the first slide guide and slides along the sloping wall in the direction of the second rest stop, whereby the bolt from its first position to the second position is moved. During the bolt stroke the pin slides the trap still along the short flank of the second link guide. The second slotted guide has an oblique extending wall in the direction of the second rest stop, the join the short flank. After the bolt stroke is done in the direction of the lock housing, the arrives Spigot of the trap in the area of the sloping wall of the second link guide, causing the latch in the lock housing is moved, thus achieving a separate from the bolt stroke Trap becomes.

advantageously, a sensor is provided which is a signal related to the lock and / or Door state and / or the state of the power transmission member a control unit that is in signal communication with the first and the second actuator is. Here can the control unit be integrated in the panic lock. Also is It is conceivable that the control unit is outside the castle is arranged, for example in the vicinity the door opening. The sensors can, for example determine if the door is open or this already in the closed state. Furthermore, the Sensor detect the condition of the trap and / or the bolt. Further a sensor may be attached to the power transmission member.

Next a fully automatic opening or closing The door can also be manually unlocked or Lock be performed. This is where the panic lock points a lock cylinder with an activation projection on, which releases the holding unit in a first rotational position, whereby the bolt from its second position in the first position can be brought is. In another of the first rotational position opposite second Drehlage contacted the lock cylinder with its activation projection the Slider on a stop area, whereby the slide of the first in the second position can be brought and so unlocking can be done manually. In the fully automatic Operation of the panic lock is by the appropriate sensors the authorized door opening, for example, over an access control system, a key switch, a Motion detectors identified and initiated.

The described different closing and opening operations relate both to the panic lock in 1 as well as in 2 , The only difference in 2 However, that is instead of the engine 3 and the drive wheel 14 a solenoid 4 is used, which is directly on the lever 20 acts. This means that during the opening and closing process via the electric motor 3 out 1 in 2 these processes by the solenoid 4 take place, the lever when actuated 20 around the actuation axis 21 turns, causing the driver 39 with the slider 10 moved from the first to the second position.

In 3 Another alternative of the panic lock is shown. Here, the panic lock has a slider 10 on, at one end with a contact surface 11 running, which is a drive wheel 14 with his spigot 19 assigned. As in 1 described is a movement of the drive wheel 14 via an electric motor 3 , whereby a translatory movement of the slider 10 is achievable. The bolt 2 is in a holding unit 12 fixed, which already in 1 is described. Furthermore, the panic lock has a lock cylinder 29 on, with which a manual unlocking and locking according to 1 and 2 can be done. One of the main differences, however, is that a trap in accordance with 1 is not provided. Furthermore, the slider has 10 a first slide tour 17 on, which has approximately a linear contour, which is at an angle to the linear direction of movement of the bolt 2 extends, wherein the angle is advantageously between 20 ° ≤ α ≤ 70 ° to ensure a reliable locking and unlocking. The first slide tour 17 has at each of its two end regions on a rest stop. While the slider 10 from its first position to the second position via the electric motor 3 or manually via the lock cylinder 29 is moved automatically takes a forced operation of the pin 32 of the bolt 2 along the first slide tour 17 ,

In 4 is another embodiment of the holding unit 12 shown. Here, the first leg 12a at its free end two locking lugs, which with the locking means 2c of the bolt 2 work together.

With this invention panic lock, for example, swing doors can be automated, with suitable closing means even closing and optionally electrically lockable. When using high melting point materials for structural components, this panic lock can also be used on fire and smoke control doors. By doing that the latch 2 via a pusher, with the lever 20 is operatively connected, can retract, the lock according to the invention also has a so-called panic function and can be used on emergency exit doors according to EN 179. It is particularly advantageous that also lock cylinder 29 can be used with undefined key withdrawal position.

By a low-friction design of the moving parts is this lock Can also be used on escape route doors according to EN 1125.

There the lock cylinder movement not with the door handle movement or the bolt movement collides leaves this lock mechanism also the use of so-called freewheeling cylinders.
