Description

The invention relates to an anti-panic push rod for actuating a door lock of an escape door or emergency exit door according to the features of the preamble of claim 1.

Such anti-panic push rod is from the WO 2013/182576 A2 known. There, an anti-panic push rod is shown in which a door lock can be unlocked via a manual actuation handle. In addition to the actuating handle, a spring accumulator is provided, which acts to assist the door lock. The spring accumulator is charged by a motor. The anti-panic push rod described has a housing with a base profile on which the individual components are mounted. This means a relatively high installation cost. In addition, the mechanical requirements of the basic profile of the anti-panic push rod are relatively high, since in the operation of the door lock by the different translations sometimes high forces.

The US 2010/0123323 A1 shows an anti-panic push rod with a motor drive unit for actuating a push rod. The motor is arranged together with a holding magnet on its own carrier profile. In order to prevent jamming in a simultaneous motor and manual operation, a compensating spring between the push rod and the engine is provided.

The object of the present invention is to provide an anti-panic push rod, which has a structurally simple construction, in particular is easy to manufacture or maintain and is constructed as compact as possible, i. takes up little space. In particular, the anti-panic push rod should have a high mechanical stability.

This object is achieved by an anti-panic push rod with the features of claim 1.

The anti-panic pressure rod according to the invention has a mechanical actuating handle and additionally a drive device which comprises a drive motor and a spring accumulator. The drive device is arranged between the base profile and the actuating handle and has a common mounting plate on which both the drive motor and the spring accumulator are mounted, wherein the slider device and the transmission device and the drive device are mounted on a continuous carrier profile, and the carrier profile in the Basic profile can be used and connected to the basic profile. Due to the common mounting plate and the holder of the slider device and the transmission device and the drive device to a continuous support profile, a Modular design of the anti-panic push rod allows. The carrier profile can be used in the basic profile and connected to the basic profile. Preferably, the carrier profile is screwed to the base profile. The separate carrier profile thus supports the essential mechanical and / or electrical components of the anti-panic push rod.

It is possible to prefabricate the carrier profile with the components supported thereon or to mount it outside the housing of the anti-panic pressure rod. When manufacturing the anti-panic push rod, the carrier profile can be used as a prefabricated structural unit or as a structural module in the basic profile and fixed there. This significantly reduces the necessary assembly steps for the production of the anti-panic push rod. Another advantage is that the stability of the anti-panic push rod is increased again via the separate carrier profile. The advantage is that the anti-panic push rod can be adjusted by cutting the basic profile to a certain width of a door. By holding the essential functional components on the separate carrier profile no complex adjustments of the mechanics are necessary.

When mounting the anti-panic push rod, the drive unit can be prefabricated as an assembly, for example, assembled outside of the housing of the anti-panic push rod and mounted as a module in the housing. This pre-assembly reduces the necessary installation work. Even during maintenance, the drive unit can be replaced as an assembly. Thus, even in the field anti-panic push rods easy repair and / or maintenance is possible. In addition, an additional mechanical stabilization is achieved via the common mounting plate. Between the drive motor and the spring accumulator act relatively high forces. In particular, when charging the spring accumulator relatively large forces must be exercised with a small stroke. It is necessary that appropriate deformations, which could lead to malfunction, be avoided as possible. About the common mounting plate such forces are absorbed and not transmitted to the housing of the anti-panic push rod. Therefore, the reliability is significantly increased on the common mounting plate. Due to the immediately adjacent arrangement of drive motor and spring accumulator also space can be reduced.

It is envisaged that the anti-panic push rod comprises the following components: a base profile which can be mounted on a door leaf, an actuating handle extending parallel to the longitudinal direction of the base profile, a slide device with at least one slide for actuating the door lock, a transmission device for transmitting a movement of the door lock Actuating handle on the slider device and a drive device connectable to the slider device, which comprises a drive motor and a spring loadable by the drive motor and / or by the actuating handle.

As a door lock, a conventional door lock, preferably a mortise find use. High security is achieved when using a self-locking panic lock.

The anti-panic push rod is mounted lying on a door leaf and thereby positioned such that the lock nut of the door lock with a driven member driven by the slider device or an output nut The anti-panic push rod is aligned. By means of a mandrel, the output member of the anti-panic push rod can be rotatably connected to the lock nut. As a mandrel, a conventional pusher mandrel may be used, for example a square.

In one embodiment, it is preferably provided that the slider device has a first slider which extends parallel to the longitudinal extent of the base profile and which is arranged between the base profile and the mounting plate. The common mounting plate is arranged in particular with a small distance above the base profile. The distance is dimensioned so that the slide just fits between basic profile and mounting plate. The slide runs between the base profile and the mounting plate, whereby the available space is optimally utilized.

It can further be provided that the slider device has a second slider extending parallel to the longitudinal extent of the base profile, which is arranged between the base profile and the mounting plate, preferably that the second slider and the first slider are arranged in a common plane.

Advantageously, it can be provided that the mounting plate is movably mounted in the longitudinal direction of the base profile, preferably that the mounting plate is mounted displaceably parallel to a slider of the slider device. To operate a door lock are depending on the lock type and local Conditions different distances necessary. Also, the slides moved by the actuating handle are moved to different extents depending on different strokes of the actuating handle. Nevertheless, in order to achieve high reliability, it is necessary to adapt the drive unit to these different distances. About the movable mounting of the mounting plate these different distances can be compensated without complex gear devices are necessary.

For a transmission of the movement of the actuating handle on the door lock can be provided that the transmission device has at least two rotatably mounted on the base profile two-armed transmission lever, wherein in each case the first arm of a transmission lever to the actuating handle and the second arm is connected to a slider of the slider device. In order to enable a possible backlash-free power transmission between the actuating handle and the door lock, it can be provided that each of the second arm of a transmission lever is toothed with a slider of the slider device, preferably by each of the end of a second arm in a recess of the slide form-fitting and / or positively engages. Due to the positive connection or toothing of the two transmission levers in the slide it is achieved that the two transmission levers are coupled together independently of the direction of displacement of the slide. Thus, the two transmission levers always move in sync with each other. This is necessary in order to avoid jamming during a one-sided loading of the actuating handle. Due to the toothing of the transmission lever with the slider, a separate connecting rod between the transmission levers omitted. Thus, this solution saves additional space and allows the anti-panic push rod is constructed as compact as possible.

To build up the anti-panic pressure bar as compact as possible, it is provided that the distance between the mounting plate and slider or base profile is minimized. In particular, it is provided that the slides are arranged immediately above the base profile and the mounting plate above the slide directly adjoins this. The mounting plate can touch a slider or the base profile in this spatially compact arrangement. Therefore, it can be provided that the resulting frictional forces are reduced by the mounting plate having on its underside a plurality of spaced apart sliding knobs or sliding surfaces, which are supported on a slide of the slider device.

The second slider may be formed as an inner slide, which is arranged between the two slide arms of the outer slide. It can further be provided that the outer slide cooperates with the drive device and that the inner slide is connected to the actuating handle. Alternatively, the inner slide can interact with the drive device and the outer slide can be connected to the actuating handle.

In order to enable a simple and reliable operation of the door lock, it can be provided that on the base profile an output nut is rotatably mounted, which is connectable via a pusher mandrel with a lock nut of a door lock. Preferably, the outer slide can be connected via a connecting rod with the rotatable output nut and rotate the output nut to actuate the connected door lock.

In order to enable actuation of the door lock both via the manual actuating device and via the drive device or the spring accumulator, it is provided in one embodiment that the outer slide and the inner slide and / or the drive device can be coupled to one another via a coupling rocker which can be actuated electrically by a coupling coil are.

A coupling of the two slides of the slide device with each other and / or with the drive device can be done by providing that the outer slide and the inner slide and / or the drive means each have a rack portion which are at least partially opposite and the coupling coil for coupling via the switchable Coupling rocker engages the rack sections of both slides to couple the outer slide with the inner slide and / or the drive unit.

Alternatively, a coupling can also be made by providing that the coupling coil is mounted on the inner slider and the outer slider has a rack portion in which the coupling rocker engages to couple the outer slide with the inner slider.

For a compact design, it can be provided that the drive device has a drive toothed rod which runs in the same plane as the rack of a slider or which subsequently extends laterally on a toothed rack of a slider.

In one embodiment it can be provided that the drive motor and / or the spring accumulator move the mounting plate relative to the base profile in order to actuate the door lock. Preferably, it is provided that the drive motor and / or the spring accumulator can be coupled to the outer slide of the slider device to move the outer slide relative to the base profile and to operate the door lock.

It is envisaged that the spring accumulator acts to support the door lock. This means, for example, if a coupling between the two drive slides fails or if an actuation stroke of the actuating handle is not sufficient to actuate the door lock, the actuation is ensured by the spring accumulator. For this it is necessary that the spring accumulator is charged. The charging of the spring accumulator can be done by the drive motor has a spindle drive with a spindle and a rotatably mounted on the spindle and linearly displaceable spindle nut. The spindle nut cooperates in a first direction of rotation of the spindle with the spring accumulator so that it is charged.

In one embodiment it can be provided that the spring accumulator is a spring which can be charged via a slide plate, preferably a gas spring, wherein the spindle drive and the slide plate are arranged concentrically with each other along a straight line.

In an advantageous embodiment, it may be provided that the drive motor both charges the spring accumulator and actuates the door lock, in particular unlocks it. For this purpose, it may be provided that the drive unit has a stop attached to the base profile or to the carrier profile and the spindle nut comes into abutment with the stop at a second, opposite to the first direction of rotation of the spindle and subsequently the drive unit, preferably the mounting plate, relative moves to the base profile to operate the door lock, in particular to unlock.

Furthermore, it can be provided that the spring accumulator comprises an armature acted upon by a switchable holding coil, wherein the holding coil is switchably fixed and / or releases the spring accumulator via the armature in the charged position. It can be provided that the slide plate of the spring accumulator has a backdrop with a holding portion and engages an anchor roller of the armature in the holding portion of the connecting link for detecting the spring accumulator.

In one embodiment it can be provided that the manually operable slide, preferably the inner slide, actuates an electrical switch to unlock the holding coil, so that the spring accumulator is released for actuating the door lock by the holding coil. This makes it possible that without a coupling between the actuating handle and the output nut or the outer slide of the slider device nevertheless an actuation of the door lock is ensured.

For use in forensic areas, for example in prisons or closed clinics, it can be provided that the release of the door lock is linked to a condition or that the release of the door lock takes place with a delay. To realize this function, it can be provided that the electrical switch is connected to the holding coil via a delay circuit and the delay circuit delays the switching signal transmitted by the electrical switch to the holding coil for enabling by a, preferably adjustable, period of time.

In particular, the delay circuit may comprise a one with a remote, i. spatially remote, release device have connectable switching input and be designed so that the time period is adjustable via the switching input. In addition, the delay circuit can transmit the signal transmitted by the electrical switch to the holding coil switching signal for enabling only after receiving an enable signal at the switching input to the holding coil.

For example, the anti-panic push rod can be connected to a central monitoring point. After triggering a panic alarm, the alarm can be checked by a person in a central monitoring station and the door lock can be unlocked. In the case of a false alarm or an abusive alarm triggering, an actuation of the door lock or an unlocking of the door lock can be prevented via the switching input of the delay circuit. This greatly extends the scope of the anti-panic push rod by allowing the anti-panic push rod to be used in appropriate forensic applications.

In practice, it is envisaged that the anti-panic push rod will be used in buildings to secure a door. The door should be secured against unauthorized inspection, but still allow an easy walk-through in an emergency. For the anti-panic push rod according to the invention is used in a door security device for securing an escape door in a building with a door lock for locking the escape door. The anti-panic push rod is mounted on the door leaf and connected to the door lock. In the area of the escape door, a door terminal with an emergency button is attached to open the escape door in an emergency. It is particularly provided that the door terminal connected to the drive motor and / or with the coupling coil and / or with the spring accumulator and is designed so that the door terminal while pressing the emergency button or a legitimate activation request the door lock on the drive motor and / or the spring accumulator unlocked or unlocked via the coupling coil manual unlocking by means of the actuating handle.

A legitimate activation request exists if an authorized person wishes to open the door. To effect the activation, for example, a key switch can be operated via a key. Alternatively, the door terminal can read a code carrier with an enabling code, for example an RFID tag. If the activation code is correct, the door terminal activates the drive motor and / or the spring accumulator in order to unlock the door lock. Alternatively, the actuating handle can be coupled via the coupling coil in order to open the door manually by actuating the actuating handle. After expiration of a release period, the door terminal can lock the door again, for example, by the operating handle is decoupled again.

The emergency button can be used to open the escape door at any time in the event of an emergency. After pressing the emergency button, the door terminal controls the drive motor and / or the spring accumulator to unlock the door lock or the door terminal controls the coupling coil to uncouple the actuating handle. At the same time an optical and / or acoustic alarm signal is emitted from the door terminal and / or an external alarm.

In the FIGS. 1 to 8 different advantageous embodiments are described, which differ in individual technical details. It is clear to the person skilled in the art that the advantageous features described here can be combined with one another. The same reference symbols designate the same components.

The Fig. 1 shows a schematic representation of a door security device 1 with an inventive anti-panic push rod 2. The anti-panic push rod 2 is mounted on a door leaf 11 of a building door resting. The door leaf 11 is designed as a hinged left wing, which is connected via hinges 13 a and 13 b pivotally connected to a door frame 12. The door may be an escape and emergency exit door, also known as a panic door. The door hinges 13a and 13b are spaced apart along a vertical axis of rotation of the door. The revolving door leaf 11 has a mortise lock 16.

The door is secured in the closed position of the door leaf 11 on the one hand on the mechanical door lock 16 and on the other via a force acting between the door frame 12 and door escape route lock 14 in the form of an electromagnet, which cooperates with an arranged on the door leaf adhesive plate. Thus, the door is secured against unauthorized inspection.

In the area close to the handle next to the door, a door terminal 15 is attached to a wall of the building. The door terminal 15 has an emergency button 151. In an emergency, the door can be unlocked via the emergency button 151.

In order to unlock the door in an emergency, the emergency button 151 is pressed. Thereafter, the door terminal 15 controls the escape route lock 14 to unlock it. At the same time an actuation of the anti-panic push rod 2 is released, so that upon actuation of the actuating handle 21 of the anti-panic push rod 2, the mechanical door lock 16 is unlocked. Then the door is unlocked and can be swung open for ascent.

The escape route lock 14 is preferably operated in the quiescent current mode. This means that when energized, the door is locked and in the de-energized state, the door is open. Thus, in the event of a power failure, it is possible to escape through the door. In an alternative embodiment of the door security device, the electrical escape route locking element 14 may also be omitted.

The anti-panic push rod 2 is mounted resting on the door leaf 11 and extends in the horizontal direction approximately at the level of the door lock 16. The anti-panic push rod 2 comprises a housing in which an actuating handle 21 and a display 22 are mounted. About the actuating handle 21, the door lock 16 can be unlocked. For this purpose, the actuating handle 21 is pressed in the direction of the door leaf 11 too. The display 22 is designed to display status messages and / or alarm messages and / or information.

The Fig. 2 shows an exploded view of the anti-panic push rod 2. The anti-panic push rod 2 has a base profile 23 which is attached directly to the door leaf 11 resting, for example, is screwed. The base profile 23 forms, so to speak, the back of the anti-panic push rod 2. The front of the anti-panic push rod 2 is formed by an actuating handle 21 which is moved to pressure on the base profile 23. On the side next to the actuating handle 21, a display 22 is arranged to display additional information or status messages to an operator. The housing of the anti-panic push rod 2 is covered laterally by cover caps 251 and 252.

On the base profile 23, a support plate 24 is attached. The support plate 24 is used for mechanical reinforcement of the base profile 23 and also holds other components of the anti-panic push rod 2. The anti-panic push rod 2 comprises a slider device 3 with extending in the longitudinal direction of the base profile slides 31, 32. Next, the anti-panic push rod 2 a Transmission device 4 for transmitting a movement of the actuating handle 21 on the slider device 3, and a drive device 5, which includes a drive motor 51 and a spring accumulator 52. These components are attached directly or indirectly to the support plate 24 and are supported on this on the base profile 23.

The slider device 3 comprises an outer slide 31, an inner slide 32 and a crank rod 33 and a driven nut 34. The transmission device 4 comprises two transmission levers 41, 42 which are rotatably mounted on receptacles 241, 242 of the support plate 24.

The drive device 5 comprises a drive motor 51 and a spring accumulator 52, both of which are mounted on a common mounting plate 54.

Furthermore, the anti-panic pressure rod 2 comprises an electrical control device 7, which is connected to individual sensors and / or switchable components of the anti-panic pressure rod 2 and electrically evaluates or controls them.

For actuating a door lock 16, the anti-panic pressure rod 2 has a driven nut 34 rotatably mounted on the base profile 23 or on the carrier profile 24. The output nut 34 is connected via a connecting rod 33 with a slider of the slider device 3 and the outer slide 31 of the slider device 3. About a mandrel, not shown, the output nut 34 is connected to a lock nut of the door lock 16. For this purpose, a conventional door handle mandrel or a corresponding square can be used. An unlocking of the door lock 16 is effected by a movement of the slide 31 corresponding to the representation of the figures to the right and while the output nut 34 is rotated via the connecting rod 33. This rotational movement is transmitted to the lock nut and acts in the direction of opening to unlock the door lock 16th

Like in the Fig. 3 is shown, the slider device 3 on an outer slide 31 which has two parallel slide arms which extend at a distance from each other. The two slide arms are each connected at their ends. Between the two slide arms of the outer slide 31 is a recess in which the inner slide 32 is arranged. The outer slide 31 and the inner slide 32 are in one common level. On the left side of the Fig. 3 It can be seen that on the outer slide 31, a pin 311 is attached, via which the connecting rod 33 is connected. The connecting rod 33 has a slot 331 in order to allow a rotation of the output nut 34 over a large angular range.

The transmission device 4 transmits an actuation of the handle 21 by means of its two transmission levers 41, 42 on the inner slide 32. The transmission levers 41 and 42 are each formed as a two-armed, rotatably mounted lever. They each have a first lever arm 411 and 421, which is connected to the actuating handle 21. The second lever arm 412 or 422 engages in a recess of the slider 32 in a form-fitting manner. Upon actuation of the handle 21, i. When the handle 21 is pressed in the direction of the base profile 23, pivot the two transmission levers 41 and 42 counterclockwise. As a result, the end of the transmission lever moves together with the middle slider 32 in the illustration of the figures to the right.

In order to unlock the door lock 16 via the actuating handle 21, the movement of the actuating handle 21 must be transferred to the lock nut. For this purpose, a coupling coil 6 is provided, whose structure in the Fig. 6 is shown in more detail. The coupling coil 6 has an electrical coil 61 which cooperates with a coupling rocker 62, which is rotatably mounted in a pivot bearing 63. Via a coupling sensor 72, the coupling state of the coil is monitored electronically and reported on to the control device 7. The coupling coil 6 is mounted on the inner slider 32.

The two slide arms of the outer slide 31 have a toothed rack section 36 in the region of the coupling coil. These two rack sections are parallel to each other and adjacent to each other. For coupling the inner slide 32 to the outer slide 31, the coupling coil 6 is de-energized, so that the coupling rocker spring-loaded with their two coupling teeth 61 engages in the toothing 36 of the two slide arms and thus couples the two slides 31 and 32 with each other. Now, if the inner slider 32 is moved via the actuating handle 21, he takes in this movement the outer slide 31 with. As a result, both slides 31, 32 move to the right. The outer slide 31 rotates via the connecting rod 33, the output nut 34 and thus unlocks the connected door lock 16th

The drive unit 5 is in the Fig. 3 represented with their individual components. The components of the drive unit 5 include the drive motor 51 and the spring accumulator 52 and the common mounting plate 54. In the Fig. 4 the drive motor 51 is shown in an enlarged view. The Fig. 5 shows the spring accumulator 52 in an exploded view.

The common mounting plate 54 supports both the drive motor 51 and the spring accumulator 52. The mounting plate 54 is slidably mounted on two sliding bearings 517 relative to the base profile 23. Via a spring, the mounting plate 54 is acted upon in its neutral position. On its underside, the mounting plate 54 in the drawings, not shown Gleitnoppen or sliding surfaces to allow sliding of the mounting plate 54 on the sliders 31 and 32 respectively. At its top, the mounting plate 54 supports the drive motor 51 and the spring accumulator 52. To disturbing torques reduce as possible, the drive motor 51 are arranged with its output and the spring accumulator 52 with its gas spring 522 in a line concentric with each other.

The drive unit 5 has two parallel racks 519, which are arranged adjacent to the rack portion 36 of the outer slide 31. In the coupling by the coupling coil 6, the coupling rocker 62 engages with its two coupling teeth 61 both in the rack portion 36 of the outer slide 31 and in the racks 519 of the drive unit 5 a. As a result, the drive unit 5 is coupled by the coupling coil 6 switchable to the outer slide 31.

The two slides 31 and 32 are each acted upon by a spring in its neutral position. This means that at rest, i. without an actuation of the actuating handle 21, the two slides are in a defined neutral position and the actuating handle is in the non-pressed state.

In order to enable a manual unlocking of the door lock at any time during power failure, the coupling coil 6 is designed as a working current coil. That is, the coupling coil 6 in the de-energized state, the inner slider 32 coupled to the outer slide 31.

In order to allow a comfortable and secure opening of the door lock 16 in each case, so even with a malfunction, in addition to the actuating handle 21, the drive unit 5 is provided for unlocking the door lock. In the event that the actuating handle 21 is already actuated before the coupling of the inner slide 32 with the Outside slide 31 is carried out, there is the possibility that either a coupling of the slide 31 and 32 is no longer possible, or that the remaining distance of the actuating handle 21 is too low to unlock the door lock 16. In order to enable unlocking of the door lock 16 in this case too, it is provided that the drive unit 5 has the spring accumulator 52 which can be charged via a motor 51. The spring 52 acts in this case supportive and is used to unlock the door lock 16.

The spring accumulator 52 has a gas pressure spring 522, which is accommodated in a housing 521. With the gas spring 522, a slide plate 55 is connected. The slide plate 55 is connected to the piston of the gas spring 522 and is moved by discharging the gas spring 522 from this to the left. To charge the gas spring 522, the slide plate 55 is moved to the right and thereby compresses the gas spring 522. The slide plate 55 is guided in a housing-fixed stop 525. The housing-fixed stopper 525 is screwed by means of two screws left and right of the mounting plate 54 with the base profile 23. The mounting plate 54 is constricted in the region of the housing-fixed stopper 525, and is slidably guided in a channel under the housing-fixed stopper 525.

The drive motor 51 has an electric motor 51 with a rotary drive. The motor 51 is accommodated in a motor housing 511. The rotary drive of the motor 51 is rotatably connected to a spindle 513 of a spindle drive. On the spindle drive 513 sits a spindle nut 518, which is linearly displaceable and non-rotatably mounted. Between the drive motor 51 and the spindle 513, a bearing 514 for reducing the friction forces is arranged.

The drive motor 51 is switched and controlled via the control device 7. The control device 7 can switch on and off the motor 51 or control or reverse the direction of rotation of the drive motor 51. In the first direction of rotation of the drive motor 51, the spindle nut 518 moves as shown in FIG Fig. 4 to the right, ie to the spring 52 to. The spindle nut actuates the slide plate 55 and thus loads the spring accumulator. In an opposite second direction of rotation of the drive motor 51, the spindle nut 518 moves in the representation of Fig. 4 to the left, ie to the motor housing 511 to. In this case, the spindle nut 518 comes into contact with the base profile fixed stop 525, in the Fig. 3 you can see. As the motor continues to rotate in this direction of rotation, due to the rotation of the motor 51, the slidable mounting plate 54 correspondingly moves to the left. That is, the spindle nut 518 pulls the drive motor 51 toward itself.

A motor unlocking the door lock 16 takes place by the outer slide 31 is taken along during the movement of the common mounting plate 54. For this purpose, the spindle drive 2 on the spindle nut 518 has two levers 515 mounted rotatably on the left and right of the spindle nut 518, which engage with their free end in a recess of the outer slide. The levers 515 are freely rotatable about their pivot bearing 516. This means that the levers 515 usually do not transmit any force to the outer slide. However, if the drive motor 51 is displaced together with its drive housing 511 to the right, so gets attached to the motor housing 511 tongue 512 in abutment with the lever 515. As a result, the lever 515 is rotated to the right, ie counterclockwise. This also results in a free end of the lever 515 Move to the right, so that the outer slide 31 moves to the right and while the door lock 16 is unlocked. By varying the distance between the pivot bearing 516 and the point of application of the tongue 512, the translation of the lever 515 and thus the path of the outer slide 31 can be adjusted. Thus, it is possible to completely unlock the door lock 16 with a relatively small distance of the drive unit 5. The drive unit 5 is moved to unlock the door lock 16 by a smaller distance than the outer slide 31st

A charging of the spring accumulator 52 takes place in the first direction of rotation of the drive motor 51, in which the spindle nut 518 moves to the right. The spindle nut 518 presses on the end of the slide plate 55 and thereby compresses the in the Fig. 5 At the end of the charging process, the slide plate 55 is displaced toward the gas spring 522 and the slide plate is fixed by the armature 524 and the holding coil 523 in this position. For this purpose, the slide plate 55 has a slide track 515 with a holding section 552. An armature roller 526 engages in the charged position of the spring accumulator 52, this holding portion, thus fixing the gas spring 522 in its charged position.

The spring accumulator 52 has a housing 521, which encloses the gas spring 522 and mechanically protects. On the housing 521 of the spring accumulator 52, a spring accumulator sensor 71 is mounted, which detects the charging state of the spring accumulator and forwards it to the electronic control device 7. At the slide plate 55 opposite end of the housing 521, a rocker switch 531 is rotatably mounted. The rocker switch 531 actuates a switch 53, which in the Fig. 2 and Fig. 3 is shown. Of the Switch 53 is connected to the armature coil 523 via an electronic delay circuit 33. An actuation of the switch 53 via a switching cam 35 which is fixed to the central slide 32.

In an emergency, i. without a preceding coupling of the two slides 31 and 32, a manual unlocking of the door lock via the actuating handle 21 proceeds as follows. Upon actuation of the actuating handle 21, the inner slider 32 is displaced to the right. In this case, the switching cam 35 moves under the rotatable switching rocker 531, which then pivots upward and the switch 53 is actuated. The interaction of the switching cam 35 with the rocker switch 531 ensures that the switch 53 is actuated over a wide operating range. Thus, it is irrelevant whether the actuating handle is pressed only a small way or whether the actuating handle is pushed to its stop. In any case, the switch 53 is reliably operated.

The switch 53 interrupts the power supply of the armature coil 523 so that it releases the slide plate 55 via the armature 524. Then, the gas spring 522 can discharge, ie the slide plate 55 is pushed to the left. Accordingly, the drive unit 5 moves with the mounting plate 54 in the opposite direction and thereby takes the outer slide 31 to unlock the door lock 16 with. Via the delay circuit 532, the time between the actuation of the switch 53 and the triggering of the spring accumulator 52 can be delayed. The delay time span is adjustable. Thus, it can be determined whether, after actuation of the manual actuating handle, the lock 16 via the Spring memory is unlocked immediately or whether only a certain amount of time elapses before unlocking the door lock 16 takes place.

In the event of a power failure, the coupling coil 6 automatically couples the inner slide 32 to the outer slide 31. This ensures that the door lock 16 can be unlocked via the actuating handle 21, even in the event of a power failure.

In order to be able to use the anti-panic push rod 2 for both right-hinged doors and left-hinged doors, it is necessary to turn the output nut 34 by 180 °. Only this ensures that the door lock is actuated and unlocked in the opening direction. However, since the space and the available path of the slide 31, 32 is limited in the anti-panic pressure rod 2 due to the space, usually the output nut 34 is rotatable only in a range between 20 ° and 60 °. This area is usually sufficient to unlock a conventional door lock 16. At the end of this turning range, the output nut 34 but comes to a stop and can not be rotated.

To avoid this disadvantage, it is provided that the connecting rod 33 has a slot 331. This slot 331 allows the output nut 34 to be rotatable 180 degrees. The slot 331 can be arranged either at the output end, as in the Fig. 3 shown, or arranged on the slider-side end of the connecting rod 33, as in the Fig. 7 and Fig. 8 shown. Is the slot 331, as in the Fig. 3 , shown in the region of the output nut 34, a pin 341 of the output nut 34 is slidably and rotatably mounted in the slot 331. The pin 341 sits at the end of an eccentric 342 which is rotatably connected to the output nut 34. It is essential here that the free distance between the output nut 34 and the connecting rod 33 is greater than the radius of the output nut 34, so that it is ensured that the output nut 34 is freely rotatable and the connecting rod 33 does not come into contact with the output nut 34 during rotation comes. By appropriate dimensioning of the length of the eccentric 342 this free distance can be adjusted.

In the Fig. 7 and Fig. 8 is a version of the anti-panic push rod 2 without external slide shown. That is, this is a purely mechanical variant of the anti-panic push rod 2, in which an unlocking of the door lock 16 takes place directly by the actuation of the actuating handle 21.

With regard to the other features, in particular with regard to the output shaft 34 rotatable by 180 °, the right in the FIGS. 7 and 8th illustrated anti-panic push rod 2 with the embodiments described in the previous figures.

When pressing the actuating handle 21, the slider 31 is also actuated here via the transmission lever 41, 42 and moved to the right. This slider 31 is connected via a pin 311 to the connecting rod 33 and takes it directly. As a result, the output nut 34 is rotated in the opening direction and unlocks the connected door lock 16th

In the representations of the Fig. 7 and Fig. 8 the slot 331 is arranged on the slider-side end of the connecting rod 33. In the slot 331 of the pin 311 of the slider 31 is received. The nut end of the Crank 33 is connected via the eccentric pin 341 with the output nut 34. Via an eccentric cam 342, the necessary distance between the nut housing 34 and the connecting rod 33 is set, so that the clear distance is sufficient to rotate the output nut 34 by 180 °.

In the Fig. 7 a first neutral position of the output nut 34 is shown. In this first neutral position, the anti-panic push rod 2 can be used for DIN right-hinged doors. The Fig. 8 shows the anti-panic push rod with the second neutral position of the output nut 34. Here, the output nut 34 is rotated by 180 ° to the first neutral position. With this neutral position, the anti-panic push rod can be used for DIN left-hinged doors.

Essential for the convertibility is that in the rotational range of the output nut 34 and its eccentric 342 engage the rotational movement-preventing components. Also, the pivoting range of the connecting rod 33 must be free of obstacles.

A conversion of the anti-panic push rod for DIN left and DIN right hinged doors is done by, for example, a doorknob with a door handle mandrel is inserted into the output nut 34 and the output pawl 34 is rotated according to the doorknob as a handle. Subsequently, the doorknob can be removed with the door handle mandrel again from the output nut 34. Subsequently, the connection to a door lock 16 or the lock nut can be produced via a conventional mandrel. So it is possible to use the anti-panic push rod 2 without constructive interference in the anti-panic push rod 2 or without modifications of components for both DIN right and DIN hinged left doors.
