Description

The invention relates to a panic lock with a lock housing, in which a spring-loaded 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 slider which translatorisch within the lock housing in a first and a second position is movable, wherein the slider has a contacting surface, which is associated with a power transmission member which is coupled to a first electrical actuating device, wherein the slider is in operative connection with the latch, that in the first position of the bolt the first electrical actuator in its activated state moves the slider from the first to the second position, whereby the latch moves to 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. 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 subject to increased wear exposed at every door operation and must be dimensioned accordingly.

It is therefore the object of the present invention to form a panic lock, which avoids the disadvantages mentioned, in particular that a panic lock is created, which has a simple structure, wherein the locking mechanism is exposed within the lock housing low loads in order to avoid high wear, thereby 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, and a second electrical actuating device engages the holding unit such that in the second position of the latch the second electrical actuating device the holding unit releases, whereby the latch moves 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 releases the holding unit and the bolt on the spring force automatically in its first position moves. 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 movable in a first and in a second position, wherein in the first position, the bolt is held in its second position. In a preferred embodiment, the latch is designed with a latching means and the holding unit with a counter-latching means. In the first position of the holding unit and in the second position of the latch engage locking means and counter-locking means into one another, preferably in this position, the bolt biases a force storage device, in particular a spring. This bias is used for the automatic bar exclusion when the holding unit is guided to 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, which acts on the leg at a distance from the axis of rotation of the holding unit, is already sufficient to release the holding unit from the bolt, which subsequently automatically moves into its first position.

Conveniently, the slide on a first link guide and the bolt on a pin which is forcibly guided in the first link guide. During the movement of the slider from the first to the second position and / or the movement of the bolt from its first position to the second position and vice versa, the pin is moved along the first link guide. Here, the slide guide can have different geometries. In one possible embodiment of the invention, the first slotted guide approximately has a linear contour which extends at an angle to the linear direction of movement of the bolt, the angle being between 20 ° ≦ α ≦ 70 °. Preferably, the first slide guide is executed at its two end regions in each case with a latching point for the pin.

Alternatively, the first slotted guide may have approximately a trapezoidal contour, wherein the first slotted guide is formed with a plurality of latching points. In the first position of the bolt, the pin may be in a first stop. In the first position of the slider and in the second position of the bolt, the pin may be located in a third detent. In the second position of the slider and in the second position of the bolt, the pin can be positioned in a second detent position. The pin moves in this case from the first link guide in a clockwise or counterclockwise direction, wherein, depending on the locking state of the lock, the pin is fixed in the respective mentioned locking point.

Vorteifhafterweise the force transmission member is a drive wheel which is rotatably mounted about an axis and having a projection-like pin at a distance from the axis, which cooperates with the contacting surface. In the first position of the slider, the pin is spaced from the contacting surface and while the drive wheel is being driven by the first actuator, the pin contacts the contacting surface and thus guides the slider to the second position.

The drive wheel may be formed, for example, as a cam wheel. For motor actuation, the panic lock according to the invention comprises an electric motor, which is designed as a first actuating device which drives the cam wheel via a worm wheel whose rotation causes a translatory movement of the slider about the axis of the cam wheel.

A measure improving the invention provides that within the lock housing, a lever is arranged, which is rotatably mounted about an actuating axis, in which an actuating member, in particular a knob, handle or the like can be fastened. Advantageously, the slide on a driver, wherein upon actuation of the actuator, the lever rotates about the actuating axis and moves with its free end, the contacting surface of the driver, whereby the slider can be brought from its first to its second position. As a result, a panic function of the lock according to the invention is realized, in which the panic lock can be opened from the inside by a corresponding actuation of the actuator in the locked state of the castle. While the lever moves the slider from its first to the second position via the driver, the pin moves along the first slide guide of the slider.

Furthermore, it can be provided that the lever, which is provided for manual operation, simultaneously acts as a force transmission member for the electrically controlled locking. Here, the lever is driven by the first actuator.

The first and / or the second actuating device can be designed as an electric motor and / or as a solenoid. The electromagnetic control via the solenoid can be done both on the working current principle and on the quiescent current principle. The reversal of the electrical direction of action is by simply switching from the outside also possible. The bolt unlocking by means of lifting magnets can be realized with small magnetic forces, especially when the magnetic voltage is intermittent, comparable to a door opener.

In a preferred embodiment of the invention, a spring-loaded latch projecting from the lock housing is provided. In this case, the case can be brought into a blocking position and into an unlocked position via a locking member arranged within the lock housing. The case can be designed as a cross latch, whereby a right and left usability of the panic lock can be achieved. In an alternative embodiment, instead of a cross latch a Rolffalle (without tax trap) are used, which is particularly advantageous for swing doors. Furthermore, it has been found that the use of damping means, which interact with the trap and / or the latch, may be advantageous for noise reduction.

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 be in data communication with an access control system, for example, which may be advantageous in the hotel sector, for example.

It has proven to be advantageous that the slider is designed with a second link guide, which has three latching points, in which a pin of the case is forcibly guided. Here, the case is extended when the pin is located at the first stop. The trap is also retracted within the lock housing when the pin is in the second and / or third rest position. Advantageously, the first slide guide of the second slide guide is adapted, which means that the first slide guide has three locking points.

Preferably, the first link guide with three locking points is designed such that the holding unit dissolves the bar located in the second position, whereby the bolt moves to its first position and at the same time moves from the third latching point in the first stop location of the first slide guide. The movement of the pin along the first link guide, starting from the third latching point to the first latching point takes place in the same direction as the movement of the bolt from its second position to its first position. It is particularly advantageous that the slider remains in its first position. The preferably biased latch is held by the holding unit and is a kind of waiting position. This latching mechanism is achieved, for example via the second electrical actuator, whereby the bolt moves into 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, which does not automatically with the Case unlocking, but is initiated separately via the second actuator. Since the slider does not have to be moved, in particular for the locking process, a low-wear lock mechanism with a low noise development is achieved.

In one possible embodiment of the invention, the slide on a spring-loaded locking element which is rotatably mounted about an axis and at least partially extends into the first link guide. Preferably moves - during 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 moves along the first slide guide of the slide, there is a contact between the pin and the projecting into the first link guide blocking element. A further movement of the pin in the direction of the first latching point causes the blocking element is moved out of the first link guide about its axis. After the pin has moved along the locking element and has reached the first stop, pivots the spring-loaded locking element automatically back and protrudes at least with an area in the first link guide, whereby a pushing back of the bolt from the locked position is effectively prevented. 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, the first and the second slide guide are formed with a short and a parallel arranged long flank, which are aligned perpendicular to the direction of movement of the latch and the bolt. Here, the short edge of the second link guide on a greater distance than the short edge of the first slotted guide, whereby a separate Fallenhub and Riegelhub can be achieved. As the pusher is moved from its first position to the second position, the peg of the latch first slides along the short flank from the first stop location. At the same time, the pin of the bolt moves from the first latching point along the short edge in the direction of the second latching point. The short flank of the first slotted guide is followed by an inclined wall in the direction of the second latching point. As the pusher is moved to the second position, the peg leaves the short flank of the first link guide and slides along the sloping wall toward the second catch location, thereby moving the latch from its first position to the second position. During the latch stroke, the pin of the latch still slides along the short edge of the second slide guide. The second slotted guide also has an inclined wall in the direction of the second latching point, which adjoins the short flank. After the bolt stroke has taken place in the direction of the lock housing, the pin of the case enters the region of the oblique wall of the second slide guide, whereby the case is moved into the lock housing, thus achieving a catch stroke separate from the bolt stroke.

Advantageously, a sensor is provided which provides a signal related to the lock and / or door state and / or the state of the power transmission member of a control unit which is in signal communication with the first and the second actuator. In this case, the control unit can be integrated in the panic lock. It is also conceivable that the control unit is arranged outside the lock, for example in the vicinity of the door opening. For example, the sensors can determine if the door is open or already closed. Further, the sensor may detect the condition of the trap and / or the latch. Furthermore, a sensor may be attached to the power transmission member.

In addition to a fully automatic opening or closing of the door, an unlocking or locking can also be performed manually. In this case, the panic lock on a lock cylinder with an activation projection, which dissolves the holding unit in a first rotational position, whereby the bolt can be brought from its second position to the first position. In another of the first rotational position opposite second rotational position of the lock cylinder contacted with its activation projection the slider at a stop area, whereby the slide can be brought from the first to the second position and so a release can be performed manually. In the fully automatic operation of the panic lock the authorized door opening, for example via an access control system, a key switch, a motion detector is identified and initiated by the appropriate sensors.

Further advantages, features and details of the invention will become apparent from the following description in which several embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description may each be essential to the invention individually or in any desired combination.

As can be seen, the slider 10 is formed with a contacting surface 11, which is associated with a force transmission member 14. The force transmission member 14 is in the present embodiment, a drive wheel which is rotatably mounted about an axis 18 and a projection-like pin 19, which acts as a kind of cam, at a distance from the axis 18. The drive wheel 14 is driven by the electric motor 3 via a worm wheel 33. Further, on the drive wheel 14, a sensor 28c is arranged. The slider 10 is operatively connected to the latch 2 such that, in the first position of the latch 2, the electric motor 3 drives the power transmission member 14, thereby moving the slider 10 from the first to the second position, at the same time locking the latch 2 in the second position moves. The exact lock mechanics will be discussed in more detail below.

The holding unit 12 is movable in a first and in a second position, wherein in the first position of the latch 2 is held in its second position, which in Fig. 1 is shown. The holding unit 12 is designed in the present embodiment L-shaped, which has a first 12a and a second leg 12b. An actuating device 4, which is a lifting magnet, acts at a distance from the axis of rotation 15 on the first leg 12a. A spring 16 arranged at a distance from the axis of rotation 15 acts on the second leg 12b. As can be seen, the latch 2 has at one end, which faces the holding unit 12, a latching means 2a, which cooperates with a counter latching means 12c of the first leg 12a.

The slider 10 is designed with a first slide guide 17, in which a pin 32 of the bolt 2 is forcibly guided. As can be seen, the first link guide 17 has three latching points 17a, 17b, 17c. The said locking points 17a, 17b, 17c hereby span a triangle. On the latch 2, a spring 34 acts.

Within the lock housing 1, a lever 20 is arranged, which is rotatably mounted about an actuating axis 21, in which an actuating member, in particular a rotary knob, handle or the like, is fastened. As in Fig. 1 is illustrated, acts on the lever 20, a spring 35th

In addition, a spring-loaded latch 5, which protrudes from the lock housing 1, is provided. For the control of the case 5, the Slider 10, a second slotted guide 22, which is adapted to the first slide guide 17 accordingly. As the contour of the first slide guide 17 and the contour of the second slide guide 22 is approximately trapezoidal. In the second slide guide 22, a pin 23 of the case 5 is positively guided. Furthermore, the second slide guide 22 has three latching points 22a, 22b, 22c. The first 17 and the second slide guide 22 are also formed with a short 17d, 22d and a parallel arranged long edge 17e, 22e, which are aligned perpendicular to the direction of movement of the case 5 and the bolt 2. As can be seen, the short edge 22d of the second link guide 22 has a greater distance than the short edge 17d of the first link guide 17, whereby a separate Fallenhub and bolt stroke is achieved.

In the upper region, the slider 10 has an actuating surface 26, which is arranged in the first position of the slider 10 spaced from a spring-loaded upper latch 27. When the slider 10 is in its second position, the actuating surface 26 contacts the top latch 27, thereby releasing it. The upper latch 27 is L-shaped in the present embodiment,
wherein this is rotatably mounted about an axis 36.

The slider 10 has a spring-loaded locking element 24 which is rotatably mounted about an axis 25 and at least partially extends into the second slide guide 22.

In the region of the case 5 and the bolt 2, a sensor 28a, 28b is arranged in each case, which determines the lock and door state. Further, another sensor, not shown, is provided for detecting the rotation angle of the door leaf, which also determines the door state. Said sensors 28a, 28b, 28c are connected to a control unit, which is not explicitly shown. Depending on an evaluation logic within the Control unit, the first 3 and the second actuator 4 are driven accordingly in order to achieve an automatic locking and unlocking of the panic lock can.

The panic lock has for manual locking and unlocking a lock cylinder 29, which is designed with an activation projection 30. In a first rotational position of the lock cylinder 29, the holding unit 12 is released, wherein the activation projection 30 contacts the free end of the free leg 12b. At the same time, the L-shaped holding unit 12 rotates counterclockwise about the axis 15, wherein the counter-locking means 12c of the first leg 12a is released from the locking means 2a of the bolt 2.

The slider 2 is designed on its lower side with a stop region 31, at which the activation projection 30 is contacted in a rotational position of the shooting cylinder 29 and can be brought from its first position to the second position by a further rotation of the lock cylinder 29 of the slider 2. In order to achieve a satisfactory lock mechanism, the slide 2 is mounted at various points 37. The slider 2 is designed at its upper end with a linkage 38. The geometry of the linkage 35 is designed so that the motor 3 is not permanently blocked in the wrong direction, but automatically a change of direction is initiated upon emergence on the linkage 38 from the wrong side after an overcurrent detection and automatically corrects the motor gearbox.

In Fig. 2 is a variant of the panic lock off Fig. 1 shown. This in Fig. 2 Panic lock shown has substantially the same features as in Fig. 1 described panic lock, so that to avoid repetition, only the following difference is addressed. In contrast to the panic lock off Fig. 1 acts the lever 14, 20, which is used for manual locking and unlocking its use, at the same time as a power transmission member. On the lever 14, 20 acts a solenoid 3, which can pivot by a control by the control unit, the lever 14, 20 in a clockwise direction about the actuating axis 21, whereby at the same time the slider 2 can be pivoted about the driver 39 upwards to the second position , The lever 14, 20 in this case has a free end which engages the contacting surface 11 of the driver 39. The operation and the technical features of the other components of the panic lock, in particular the top lock 27, the slider 10, the case 5, the bolt 2, the holding unit 12 correspond to the descriptions Fig.1 ,

The following is based on the mechanics of the panic lock according to Fig. 1 and Fig. 2 received, with different opening and closing situations may be present.

Closing without locking

A1:

The door is in the open position. At the same time, the latch 2 is in its second position, with the holding unit 12 holding the latch 2 reliably. The trap 5 is in its extended position as in FIG Fig. 1 and Fig. 2 shown. The lever 20 is in its initial position, wherein the lock cylinder 29 is in a key withdrawal position. The solenoid 4 is in its rest position and the electric motor 3 is deactivated.

A2:

The door is closed, at the same time the latch 5 is pushed back by the lock plate, not shown, into the lock housing 1. In this case, the pin 23 moves from the first latching point 22a within the second slide guide 22 in the direction of the third latching point 22c.

A3:

The door is closed, wherein the latch spring-loaded 5 jumps out of the lock housing 1 in the lock plate opening, not shown, and holds the door on the locking surface of the case 5 in a closed state. The pin 23 is again in the position of the first latching point 22a with the door closed. The bolt 2 remains in its second position in latching.

Closing process with electrically controlled self-locking

B1:

The door is in the open state, see A1.

B2:

The door closes with the sensor 28b engaging the striker area.

B3:

B5:

The door is in a closed state and is locked at the same time. Here, the self-retaining latch 2 is released from the holding unit 12, wherein the bolt 2 extends by means of the spring bias in its first position. Starting from the third latching point 17c, the pin 32 moves horizontally along the first slide guide 17 to the first latching point 17a. While the pin 32 moves horizontally in the direction of the first latching point 17a along the slide guide 17, the pin 32 pushes the locking element 24 from the first slide guide 17 in a clockwise direction around the axis of rotation 25th out. After the pin 32 has reached the first latching point 17a, the locking element 24 lowers counterclockwise back to its original position, wherein it extends at least partially into the slotted guide 17 with its free end. In this position, the locking element 24, a pushing back of the bolt 2 is prevented in its second position. It is particularly advantageous that the locking process just described essentially by the movement of the bolt 2 and the locking element 24 takes place without moving the slider 10 from its first, lower position.

The described different closing and opening operations relate both to the panic lock in FIG. 1 as well as in FIG. 2 , The only difference in Fig. 2 is, however, that instead of the motor 3 and the drive wheel 14, a solenoid 4 is used, which acts directly on the lever 20. This means that during the opening and closing operation on the electric motor 3 off FIG. 1 in FIG. 2 these operations take place by means of the lifting magnet 4 which, when actuated, rotates the lever 20 about the actuating axis 21, as a result of which the carrier 39 with the slider 10 is moved from the first to the second position.

In FIG. 3 Another alternative of the panic lock is shown. Here, the panic lock on a slide 10, which at one end is designed with a contacting surface 11 which is associated with a drive wheel 14 with its pin 19. As in FIG. 1 described is a movement of the drive wheel 14 via an electric motor 3, whereby a translational movement of the slider 10 can be achieved. The bolt 2 is fixed in a holding unit 12, which is already in FIG. 1 is described. Furthermore, the panic lock on a lock cylinder 29, with a manual unlocking and locking according to FIG. 1 and FIG. 2 can be done. One of the main differences, however, is that a trap in accordance with FIG. 1 is not provided. Furthermore, the slider 10 has a first slide guide 17, which has approximately a linear contour which extends at an angle to the linear direction of movement of the bolt 2, wherein the angle is advantageously between 20 ° ≤ α ≤ 70 ° to a reliable Ver - And unlocking process to ensure. The first link guide 17 has at each of its two end regions a latching point. While the slider 10 is moved from its first position to the second position via the electric motor 3 or manually via the lock cylinder 29, there is automatically a positive guidance of the pin 32 of the bolt 2 along the first slide guide 17th

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

With this inventive panic lock, for example, swing doors can be automated, with suitable closing means also self-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. The fact that the latch 2 can be retracted via a pusher, which is in operative connection with the lever 20, the lock according to the invention also has a so-called panic function and can at emergency exit doors according to EN 179 are used. It is particularly advantageous that lock cylinder 29 can be used with undefined key withdrawal position.

Due to the low-friction design of the moving parts, this lock can also be used on escape route doors according to EN 1125.

Since the lock cylinder movement does not collide with the door handle movement or the bolt movement, this lock mechanism also allows the use of so-called freewheel cylinders.
