Description

DESCRIPTION

Universal panic pressure bar

The invention relates to a panic pressure bar for actuating a door lock of an escape door or emergency exit door according to the features of the preamble of claim 1.

Such a pressure bar is known from WO 2013/182576 A2. This panic pressure bar is mounted that is supported on a door leaf and features a manually operated handle to unlock a door lock. The drive handle is housed in a base profile and can be operated by manual pressure in the direction of the door wing. The movement of the drive handle is transmitted to a sliding device and an outlet bushing. The outlet bushing is connected to a door lock to unlock it. The panic pressure bar can only be used or for right-mounted door wings according to DIN standard or in a constructively modified embodiment for left-mounted door wings according to DIN standard. A utilization capacity of this panic pressure bar for door wings mounted both to the left according to the DIN standard and to the right according to the DIN standard is not possible.

From EP 1355 024 B1 a panic pressure bar is known which can be selectively adapted and can be used both on door wings mounted on the right and on door wings mounted on the left. This panic pressure bar has a pivoting pressure bar that is housed in a door wing by means of two supports. Both supports of the pressure bar respectively have a spring loaded locking pin that cooperates with an elongated hole of the pressure bar. To change the panic pressure bar from doors mounted on the right to doors mounted on the left, the spring-loaded locking bolt sinks and the pressure bar itself pivots around a certain angular area. Next, the pressure bolt that locks into a second elongated hole. Thus, a selective use of this pressure bar is possible for doors mounted on both the right and the left.

GB 2445 948 A shows a panic pressure bar for a bar locking device arranged so that it rests on a door leaf. To use the panic pressure bar for doors mounted on the right according to the DIN standard and on the left according to the DIN standard, an eccentric lever rotated 0 ° or 180 ° is used before mounting and then the panic pressure bar is mounted. To change it, you have to open the panic pressure bar and modify the orientation of the eccentric lever.

GB 2287506 A shows another panic pressure bar that can be changed to the right / left for a bar locking device arranged so that it rests on a door leaf. In this case, for the shift to the right / to the left, a T-lever that can be changed is used, which can be rotated, for the change, in an area less than 60 °. In the change the connection point of the T-lever in the sliding mechanics must be modified.

Also US 6,820,905 B1 shows a panic pressure bar that can be changed to the right / left for a bar locking device arranged so that it rests on a door leaf. In this case, a three-arm rotary lever is used for the right / left shift. Also in this case, during the change, the lever connection point is modified.

The objective of the present invention is to create a panic pressure bar that has great operational safety with a spatially compact structure and that can be used universally. According to the invention, the panic pressure bar can be used for both right-mounted doors and left-mounted doors without constructive intervention in the panic pressure bar.

This objective is solved, according to the invention, by a panic pressure bar with the characteristics of claim 1, as well as by a method with the characteristics of claim 13.

The panic pressure bar according to the invention has a manually operated handle that acts on a sliding device. The sliding device comprises an outlet bushing that can be joined with a lock bushing of the door lock by means of a pin.

The panic pressure bar is intended to comprise the following components: a base profile, which can be mounted so that it rests on a door leaf; a drive handle, which extends parallel to the longitudinal direction of the base profile, drive handle that is housed so that it can move relative to the base profile; a sliding device with at least one slide, which is connected to an outlet bushing, by means of a connecting rod, for actuating the door lock; and a transmission device for the transmission of a movement of the drive handle to the sliding device, the output bushing being able to be connected with a door lock of the door lock by a pin and the connecting rod being connected at one end with a slide of the sliding device by means of a pin and being housed at its opposite end in the outlet bushing by means of the bolt so that it can rotate. In this context, eccentrically it means that the bolt is arranged offset a certain length outside the axis of rotation of the outlet bushing. To adjust this length, it can be provided that the bolt is connected to the outlet bushing by means of an eccentric cam fixed to the outlet bushing with rotation protection. By means of the connection with protection against rotation of the eccentric cam with the outlet bushing, the traction movement transmitted from the connecting rod to the bolt is transformed into a rotation movement of the outlet bushing.

In accordance with the invention, the outlet bushing has two neutral positions, the first neutral position being provided for door leaves mounted on the right and the second neutral position being provided for door leaves mounted on the left, and the bushing being housed output so that it can rotate 180 ° to get from the first neutral position to the second neutral position. This makes it possible, easily, by turning the outlet bushing, to change the panic pressure bar from a panic pressure bar that can be used on the left according to DIN standard to a panic pressure bar that can be used at right according to DIN standard. Above all, no constructive intervention in the panic pressure bar is necessary for this. No component should be replaced or disassembled. This capacity for easy change of the panic pressure bar increases its scope, as it were, in terms of factor 2. At the same time the necessary storage is reduced, since through this capacity of universal use of the pressure bar Antipanic should be stored a considerably smaller number of variants.

A conventional recessed lock can be used as a door lock. Great security is achieved when a panic lock with self-locking is used as a door lock. In this case, the door always locks automatically when the rotation wing of the door reaches the closed position.

The panic pressure bar is usually mounted in such a way that it rests on a door wing and is placed, in this respect, so that the exit door of the door lock is aligned with an exit element actuated by the Sliding or with an outlet bushing of the panic pressure bar. By means of a pin, the exit element of the panic pressure bar can be connected to the outlet bushing with protection against rotation. As a pin, for example, a conventional latch pin, especially a square, can be used. It connects the outlet bushing of the panic pressure bar with a lock bushing of the door lock with turn protection. This ensures that the rotations of the outlet bushing are transmitted to the lock bushing.

Neutral position means a position of the outlet bushing in which the handle is not actuated. It is, as it were, a resting position of the panic pressure bar or the outlet bushing. Especially it can be provided that the outlet bushing is pressed by a spring until it reaches the first neutral position and / or the second neutral position. The spring can, for example, cooperate with the sliding device, especially being connected to a sliding device slide. Especially a neutral position of the outlet bushing corresponds to a position of the locking bushing in which a door latch inserted in the outlet bushing would be oriented horizontally.

The transmission device may comprise transmission elements for converting a movement of the drive handle in the direction of the base profile into a movement of a slide of the sliding device parallel to the base profile or parallel to the door surface, circumstances or The spatial dimensions of the panic pressure bar limit the available travel of the drive handle or the possible travel of the sliding device. At the latest when the sliding device collides, in its path, with a housing or with other components of the panic pressure bar, this stop limits the possible travel of the slide. A complete drive or a complete travel of the drive handle corresponds to a rotation of the outlet bushing or a rotation in this lock bushing connected in the same area as in the case of a lock of the lock by means of a door handle, that is, usually from 15 ° to 20 °. In practice it has been shown that with the spatial circumstances the outlet bushing can pivot through the sliding equipment in an angular area between 20 ° and 60 °, preferably between 30 ° and 50 °, before the sliding equipment collides with a cap. To rotate the necessary 180 ° to the outlet bushing, however, it is necessary that both the outlet bushing and the connecting rod connected to the outlet bushing can rotate freely beyond the entire rotation or pivot zone. This implies that there must be sufficient travel and no component can be arranged either in the pivot zone of the connecting rod or in the rotation zone of the outlet bushing.

To save construction height in a configuration, it can be provided that the bolt is arranged aligned with the outlet bushing and the connecting rod in a plane.

In an alternative configuration it can also be provided that the bolt is arranged on the outlet bushing or on a component connected to the outlet bushing and that it is arranged with a displacement relative to the outlet bushing in the direction of the drive handle, that is to say , that the bolt is arranged in a plane that is located above the outlet bushing. Above the outlet bushing means in the direction of the drive handle.

To facilitate the necessary travel, also with limited travel of the sliding equipment, to rotate the outlet bushing from the first neutral position to the second neutral position 180 °, it may be provided that the connecting rod has an elongated hole in the area of the bushing. outlet in which the bolt is housed so that it can pivot and rotate. In addition or alternatively, it may also be provided that the connecting rod in the area of the slide has an elongated hole in which the pin held in the slide is housed so that it can move and rotate, or that the connecting rod present in the area of its end of the sliding side a pin that is housed in the elongated hole of the slide so that it can move and rotate.

By means of an elongated hole in the connecting rod or the two elongated holes in the connecting rod it is possible that the bolt can be rotated too much, even when the sliders themselves are locked. This makes it possible to rotate the outlet bushing even in the case of a locked slide or when a slide of the sliding device has reached a stop. With the activation of the door lock, especially with the opening of the door lock, the bolt of the outlet bushing is subject only to traction. In this case the bolt is adjusted in the area of the outer end of the elongated hole. In this way, a traction is transmitted in the connecting rod, almost without delay, to the bolt, and it is transformed into a rotation of the outlet bushing to unlock the door lock. With the change from the first neutral position to the second neutral position, the outlet bushing is operated in the same direction of rotation, that is, in the direction of rotation that is necessary to open the lock. Through the elongated hole, the necessary travel for the rotation of the 180 ° outlet bushing is facilitated. This ensures that, on the one hand, an opening of the door lock is possible without delay and without play in most cases and, on the other hand, the necessary travel to rotate the outlet bushing 180 is guaranteed. °.

In order to transmit the movement of the drive handle to the sliding device, in one configuration it may be provided that the transmission device has at least two two-arm transmission levers housed in the base profile so that it can rotate, the device being connected respectively first arm of a transmission lever with the drive handle and the second arm, with a slide of the sliding device. In order to achieve, in this respect, a compact configuration that occupies the least possible construction space, it may preferably be provided that the second arm of the at least two transmission levers is serrated with a slide of the sliding device, preferably engaging respectively the end of the second arm, by dragging in a cavity of the slide. By means of the teeth of the two transmission levers with the slide of the sliding device, it is guaranteed that the two transmission levers are joined together and that they run synchronously in all directions. This is necessary to ensure that, with a pressure on the one hand on the drive handle, the drive handle does not get stuck, but by synchronous movement of the two transmission levers moves towards the base profile. By means of the teeth of the two transmission levers, a connecting bar, otherwise necessary, between the transmission levers can be dispensed with.

In one configuration it may be provided that the panic pressure bar has a drive unit to favor the unlocking of the door lock. The drive unit preferably comprises a spring-loaded pressure accumulator and an electric drive motor. The spring-loaded pressure accumulator can be charged by means of the electric drive motor. By means of the spring-loaded pressure accumulator, manual unlocking of the door lock can be favored.

Especially it can be provided that the slide device has two slides, the first slide having its path parallel to the second slide and the first slide being able to move from a switchable spring-loaded accumulator and / or from a switchable drive motor for the door lock drive. By means of the two slides, the manual drive handle is decoupled from the drive unit, so that a high level of operational safety is guaranteed, since the two drives, specifically the manual drive handle and the drive equipment with the Spring loaded pressure accumulator is not hindered on the opposite side.

In particular, it can be provided that the first slide is configured as an external slide and has two slide arms that have their path in parallel with a space from one to the other, slide arms that are connected to each other, and that the second slide is configured as an inner slide and is arranged between both sliding arms of the outer slide. In this regard, it may be especially provided that the connecting rod is connected to the first slide.

In order to enable safe unlocking of the door lock at all times and at the same time to facilitate manual opening by means of the drive handle by means of the drive unit, in a configuration it can be provided that a switchable coupling coil will engage , so that the first slide with the second slide can be switched electrically by means of a coupling rocker. By coupling both slides together, a movement of the manually operated handle is transmitted directly to the second slide and thus to the outlet bushing. In order to guarantee at all times, that is to say, also in the event of a power failure, an unlocking of the door lock, it is especially provided that the coupling coil engages, in a state without power, the first slide with the second slide. For this, the rotary coupling rocker is spring loaded with the first slide and The second slide. When supplying current, the coupling coil tightens the coupling rocker and disengages, thus, the two slides.

In one configuration it can be provided that the coupling is carried out by presenting the first slide and the second slide respectively a rack section that are opposite each other, at least by sections, and by engaging the coupling coil, by means of the coupling rocker , in both sections of rack to connect the outer slide with the inner slide. Alternatively, it can also be provided that the coupling coil is fixed on the second slide and that the first slide has a rack section in which the coupling rocker engages to couple both slides together. In practice, it is intended that the panic pressure bar be used in buildings to secure a door. The door must be secured against unjustified access but, nevertheless, make it possible to access without problems in case of emergency. For this, the panic pressure bar according to the invention is used in a door securing device to secure an escape door in a building with a door lock to block the escape door. The panic pressure bar is mounted, in this respect, so that it rests on the door wing and is connected to the door lock. In the area of the escape door is placed a door terminal with an emergency button to open the escape door in case of emergency. In this regard, it is especially provided that the door terminal is connected with the coupling coil and / or with the spring-loaded accumulator and that it is configured so that the door terminal, with the emergency button pressed or in case of With justified activation request, unlock the door lock by means of a drive motor and / or the spring-loaded pressure accumulator or activate, by means of a coupling coil, a manual release by means of the drive handle.

Before mounting the panic pressure bar on the exhaust door, it must be adjusted to the corresponding door mounted on the right or mounted on the left. To switch between a door mounted on the right and a door mounted on the left, it is especially provided that a door latch pin provided with a handle is used to pass the outlet bushing from the first neutral position to the second neutral position or vice versa , the door latch pin being inserted into a pin housing of the outlet bushing and rotating the outlet bushing 180 ° by the handle.

The change can be used, in this regard, easily, using as a handle a door handle. This has the advantage that no special tool is necessary for changing the panic pressure bar, but a conventional door handle can be used.

After adjusting the panic pressure bar to the door mounted to the right or to the left, it may be especially provided that, after passing the outlet bushing to a corresponding neutral position, the handle is removed with the doorknob pin of the bushing. Exit and instead of this, a pin for the connection of the outlet bushing with a door lock is inserted into the pin housing of the outlet bushing. After joining the panic pressure bar with the door lock by means of the pin, it has been ensured that the door lock can be operated and unlocked reliably by means of the panic pressure bar.

Figures 1 to 8 describe different advantageous configurations that differ in individual technical details. It is clear to the expert that the advantageous features described in this regard can be combined with each other. The same reference numbers indicate equal components.

Figure 1 shows in a schematic representation a door securing device 1 with a panic pressure bar 2 according to the invention. The panic pressure bar 2 is mounted so that it rests on a door leaf 11 of a building door. The door leaf 11 is configured as a hinged wing mounted on the left which is pivotally connected, by means of door hinges 13a and 13b, with a door frame 12. As for the door it can be an escape door or route door of evacuation, also called panic door. The door hinges 13a and 13b are arranged separated from each other along a door rotation axis. The swinging door wing 11 has a recessed lock 16.

In the closed position of the door wing 11, the door is secured, on the one hand, by means of the mechanical door lock 16 and, on the other hand, by means of an escape route blocking device acting between the frame. of door 12 and door wing in the form of an electromagnet that cooperates with an adhesive plate disposed on the door leaf. Thus, the door is secured against unjustified access.

In the area near the grip, a door terminal 15 is placed next to the door on a wall of the building. The door terminal 15 has an emergency button 151. In an emergency, the door can be unlocked by means of the emergency button 151.

To unlock the door in case of an emergency, press the emergency button 151. Consequently, the door terminal 15 activates the escape route blocking device 14 to unlock it. At the same time, a drive of the panic pressure bar 2 is activated, so that with a drive of the drive handle 21 the panic pressure bar 2 is unlocked, the mechanical door lock 16 is unlocked. Consequently, the door wing is unlocked and can pivot upwards to make access possible.

The escape route blocking device 14 is preferably operated in the idle current mode. This means that in the delivery state the door is locked and in the powerless state the door is open. Thus, in the event of a power failure, an escape through the door is possible. In an alternative configuration of the door securing device, the electrical escape route blocking element 14 can also be dispensed with.

The panic pressure bar 2 is fixed so that it rests on the door wing 11 and has its path in a horizontal direction, approximately at the height of the door lock 16. The panic pressure bar 2 comprises a housing in which a drive handle 21 and a screen 22 are housed. By means of the drive handle 21 the door lock 16 can be unlocked. To this end, the drive handle 21 is pressed in the direction of the door wing 11. The screen 22 It is configured to indicate status messages and / or alarm messages and / or data.

Figure 2 shows an exploded representation of the panic pressure bar 2. The panic pressure bar 2 has a base profile 23, which is fixed, for example, screwed, so that it rests directly on the door wing 11. The base profile 23 forms, so to speak, the rear side of the panic pressure bar 2. The front side of the panic pressure bar 2 is formed by a drive handle 21 that moves when pressure is applied to the base profile 23. Laterally, next to the drive handle 21, a screen 22 is provided to indicate additional information or status messages to a user. The housing of the panic pressure bar 2 is covered laterally by means of cover caps 251 and 252.

A support plate 24 is fixed on the base profile 23. The support plate 24 serves to mechanically reinforce the base profile 23 and also supports other components of the panic pressure bar 2. The panic pressure bar 2 comprises a device of slide 3 with sliders 31, 32 extending in the longitudinal direction of the base profile. In addition, the panic pressure bar 2 has a transmission device 4 for transmitting a movement of the drive handle 21 to the slide device 3, as well as a drive device 5, comprising a drive motor 51 and a pressure accumulator by spring 52. These components are fixed directly or indirectly to the support plate 24 and are supported by means of this in the base profile 23.

The slide device 3 comprises an outer slide 31, an inner slide 32, as well as a connecting rod 33 and an outlet bushing 34. The transmission equipment 4 comprises two transmission levers 41, 42, which are housed in housings 241, 242 of the support plate 24 so that they can rotate.

The drive device 5 comprises a drive motor 51 and a spring-loaded pressure accumulator 52, which are fixed on a common mounting plate 54.

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

For actuating a door lock 16, the panic pressure bar 2 has an outlet bushing 34 housed in the base profile 23 or in the support profile 24 so that it can rotate. The outlet bushing 24 is connected, by means of a connecting rod 33, with a slide of the slide device 3 or with the outer slide 31 of the slide device 3. By means of a pin not shown, the outlet bushing 34 is attached with a lock sleeve of the door lock 16. A conventional door latch pin or a corresponding square can be used for this. An unlock of the door lock 16 is effected producing a movement of the slide 31, according to the representation of the figures, to the right and, in this respect, rotating the outlet bushing 34 by means of the connecting rod 33. This rotational movement is transmitted to the outlet bushing and acts in the opening direction to unlock the door lock 16.

As shown in FIG. 3, the sliding equipment 3 has an outer slide 31, which has two parallel sliding arms that have their travel separated from each other. Both sliding arms are joined together respectively by their ends. Between the two sliding arms of the outer slide 31 is a cavity, in which the inner slide 32 is arranged. The outer slide 31 and the inner slide 32 are located in a common plane. On the left side of Figure 3 it should be noted that a pin 311 is attached to the outer slide 31 by means of which the connecting rod 33 is connected. The connecting rod 33 has an elongated hole 331 to make it possible for the outlet bushing 34 to rotate in a large angular area.

The transmission device 4 transmits a drive of the handle 21, by means of its two transmission levers 41, 42, to the inner slide 32. The transmission levers 41 and 42 are respectively configured as two-arm levers housed so that they can rotate. They respectively have a first lever arm 411 or 421, which is connected to the drive handle 21. The second lever arm 412 or 422 engages in a groove in the slide 32. During a handle operation 21, it is that is, when the handle 21 is pressed in the direction of the base profile 23, the two transmission levers 41 and 42 pivot counterclockwise. In this way, the end of the transmission levers moves together with the middle slide 32, in the representation of the figures, to the right.

To unlock the door lock 16 by means of the drive handle 21, the movement of the drive handle 21 must be transmitted to the lock bushing. For this, a coupling coil 6 is provided, the structure of which is shown in more detail in Figure 6. The coupling coil 6 has an electric coil 61 that cooperates with a coupling rocker 62, which is housed in a rotating bearing 63 so that it can rotate. The coupling state of the coil is monitored electronically by means of a coupling sensor 72 and forwarded to the control equipment 7. The coupling coil 6 is fixed on the inner slide 32.

The two sliding arms of the outer slide 31 have a rack section 36 in the area of the coupling coil. These two rack sections are positioned parallel to each other and border on each other. To couple the inner slide 32 to the outer slide 31, the coil 6 is connected without current, so that the rocker 62 engages, spring loaded with its two coupling teeth 61, in the teeth 36 of the two sliding arms and Thus, it couples both slides 31 and 32 with one another. Now, when the inner slide 32 is moved by means of the drive handle 21, it drives the outer slide 31 with this movement. In this way, both slides 31, 32 move to the right. The outer slide 31 rotates, in this respect, via the connecting rod 33, the outlet bushing 34 and thus unlocks the connected door lock 16.

The drive unit 5 is shown in Figure 3 with its individual components. The components of the drive unit 5 comprise the drive motor 51 and the spring-loaded pressure accumulator 52, as well as the common mounting plate 54. Figure 4 shows the drive motor 51 in enlarged representation. Figure 5 shows the spring loaded pressure accumulator 52 in an exploded representation.

The common mounting plate 54 supports both the drive motor 51 and the spring pressure accumulator 52. The mounting plate 54 is housed so that it can be moved, by means of two sliding bearings 517, with respect to the base profile 23. By means of a spring, the mounting plate 54 is pressed until it reaches its neutral position. On its lower side, the mounting plate 54 has slide buttons or sliding surfaces not shown in the drawings to allow a sliding of the mounting plate 54 on the slides 31 or 32. On its upper side the mounting plate 54 it supports the drive motor 51 and the spring pressure accumulator 52. To reduce as much as possible annoying torque, the drive motor 51 with its drive and the spring pressure accumulator 52 with its compression spring by Gas 522 are arranged in a line concentrically with respect to each other.

The drive unit 5 has two parallel zippers 519 that are arranged adjacent to the rack section 36 of the outer slide 31. With the coupling via the coupling coil 6, the coupling rocker 62 engages with its two coupling teeth 61 both in the rack section 36 of the outer slide 31 as in the zippers 519 of the drive unit 5. In this way, the drive unit 5 is coupled to the outer slide 31 so that it can be switched by means of the coupling coil 6.

The two slides 31 and 32 are pressurized respectively by a spring until they reach their neutral position. This means that in the rest position, that is, without a drive of the drive handle 21, the two slides are located in a defined neutral position and the drive handle is in a non-pressed state.

To make it possible at all times, also in the event of a power failure, a manual unlocking of the door lock, the coupling coil 6 is configured as an operating current coil, that is to say that the coupling coil 6 in a state without current Attach the inner slide 32 with the outer slide 31.

In order to make it possible in all cases, that is to say, also in case of incorrect operation, a comfortable and safe opening of the door lock 16, in addition to the drive handle 21, the drive unit 5 for unlocking the door lock is provided. door. If the door handle 21 is operated before the coupling of the inner slide 32 with the outer slide 31 is made, it is possible that a coupling of the sliders 31 and 32 is no longer possible or that the Remaining travel of the drive handle 21 is too short to unlock the door lock 16. To also make it possible, in this case, to unlock the door lock 16, it is provided that the drive unit 5 presents the pressure accumulator by spring 52 that can be charged by means of a motor 51. The spring pressure accumulator 52 acts in this case to favor and is used to unlock the door lock 16.

The spring pressure accumulator 52 has a gas compression spring that is housed in a housing 521. With the gas compression spring 522 a slide plate 55 is attached. The slide plate 55 is connected to the spring piston gas compression 522 and moves, when the gas compression spring 522 is unloaded, from this to the left. To slide the gas compression spring 522 the slide plate 55 moves to the right and compresses, in this respect, the gas compression spring 522. The slide plate 55 is driven in a stop 525 fixed to the housing. The fixed stop to the housing 525 is screwed with the base profile 23 by means of two screws to the left and to the right of the mounting plate 54. The mounting plate 54 is tightened in the area of the stop 525 fixed to the housing, and it is conducted, so that it can be moved, in a channel with the stop 525 fixed to the housing.

The drive motor 51 has an electric motor 51 with a rotary force output. The motor 51 is housed in a motor housing 511. The rotational force output of the motor 51 is connected with rotation protection with a spindle 513 of a spindle drive. On the spindle drive 513 there is a spindle nut 518, which is housed so that it can move linearly and cannot rotate. Between the drive motor 1 and the spindle 513 a support 514 is arranged to reduce frictional forces.

The drive motor 51 is connected and activated by means of the control device 7. The control device 7 can, in this respect, turn the motor 1 on and off 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, in accordance with the representation of figure 4, to the right, that is, towards the spring loaded pressure accumulator 52. In this respect, the nut Spindle drives the slide plate 55 and thus loads the spring-loaded pressure accumulator. In a second direction of opposite rotation of the drive motor 51, the spindle nut 518 moves, in the representation of Figure 4, to the left, that is, towards the motor housing 511. In this respect, the nut of Spindle 518 comes to play with the stop 525 fixed to the base profile, stop which can be seen in Figure 3. As the motor continues to rotate in this direction of rotation, as a result of the rotation of the motor 51 the movable mounting plate 54 it moves correspondingly to the left, that is, the spindle nut 518 brings the drive motor 51 towards itself.

A motor release of the door lock 16 is carried out by dragging the outer slide 31 with the movement of the common mounting plate 54. For this, the spindle drive 2 has two levers 515 on the spindle nut 515 housed on the left and right on the spindle nut 518 so that they can rotate, levers that engage with their free end in a slide cavity Exterior. The levers 515 can rotate freely around their rotary bearing 516. This means that the levers 515 usually do not transmit any force to the outer slide. However, the drive motor 51 moves to the right together with its drive housing 511, so that a tab 512 attached to the motor housing 511 comes to play with the lever 515. In this way the lever 515 rotates towards the right, that is, counterclockwise. This results in the free end of the lever 515 also a movement to the right, so that the outer slide 31 moves to the right and, with this, the door lock 16 is unlocked. By varying the space between the rotary bearing 516 and the grip point of the tongue 512, the transmission ratio of the lever 515 can be adjusted and, thus, the travel of the outer slide 31. Thus, it is possible to completely unlock the lock of door 16 with a relatively short travel of the drive unit 5. To unlock the door lock 16 the drive unit 5 moves with a shorter travel than the outer slide 31.

A loading of the spring loaded pressure accumulator 52 is carried out in the first direction of rotation of the drive motor 51, in which the spindle nut 518 goes to the right. In this regard, the spindle nut 518 presses on the end of the slide plate 55 and compresses, in this respect, the gas compression spring 522 of the spring-loaded pressure accumulator 52, shown in Figure 5. At the end of the loading process the slide plate 55 is moved towards the gas compression spring 522 and the slide plate is fixed in this position by the anchor 524 and the retention coil. For this, the slide plate 55 has a sliding rail 515 with a retaining section 552. In the loaded position of the spring-loaded accumulator 52 a Anchor roller 526 pushes this retaining section from behind and thus fixes the gas compression spring 522 in its loaded position.

The spring pressure accumulator 52 has a housing 521 that surrounds the gas compression spring 522 and protects it mechanically. In the housing 521 of the spring pressure accumulator 52 is housed a spring pressure accumulator sensor 71 which detects the state of charge of the spring pressure accumulator and transmits it to the electronic control equipment 7. At the end of the housing 521 opposite the slide plate 55 is housed so that a switching rocker 531 can rotate. The switching rocker 31 operates a switch 53, which is shown in Figure 2 and in Figure 3. The switch 53 is connected to the anchor coil 523 by means of an electronic delay circuit 33. A switch 53 is operated by means of a switching cam 35 that is fixed to the middle slide 32.

In an emergency, that is, without a prior coupling of the two slides 31 and 32, manual unlocking of the door lock is produced by means of the drive handle 21 as follows. With the actuation of the drive handle 21, the inner slide 32 moves to the right. In this respect, the switching cam 35 passes under the rotating switching rocker 531, which consequently pivots up and drives the switch 53. By means of the cooperation of the switching cam 35 with the switching rocker 531 it is guaranteed that the switch 53 is operated beyond a wide actuation zone. Thus, the fact that the drive handle is only pressed for a short distance or that the drive handle is pressed until it reaches its stop is unimportant. In any case, switch 53 is operated reliably.

The switch 53 interrupts the supply of the anchor coil 523, so that, by means of the anchor 524, it releases the slide plate 55. Accordingly, the gas compression spring 522 can be discharged, that is, the Sliding plate 55 is pressed to the left. Accordingly, the drive unit 5 moves with the mounting plate 54 in the opposite direction and draws, in this respect, the outer slide 31 to unlock the door lock 16. By means of the delay circuit 532, the time between the operation of the switch 53 and the activation of the spring pressure accumulator 52 can be delayed. The delay time interval can be adjusted. Thus, it can be determined whether after the manual actuation handle of the lock 16 is operated by means of the spring-loaded pressure accumulator, it is unlocked immediately or if a certain interval of time passes before an unlocking of the door lock 16 is carried out.

In the event of a power failure, the coupling coil 6 couples the inner slide 32 with the outer slide 31 automatically. In this way, also in the event of a power failure, it is guaranteed at all times that the door lock 16 can be unlocked by means of the drive handle 21.

In order to use the panic pressure bar 2 both for doors mounted on the right according to DIN standard and for doors mounted on the left according to DIN standard, it is necessary to rotate the outlet bushing 34 180 °. Only in this way is it guaranteed that the door lock is operated and unlocked respectively in the opening direction. However, since the construction space and the available travel of the slides 31, 32 in the panic pressure bar 2 are limited by the construction space, usually the outlet bushing 34 can rotate only in a range between 20 ° and 60 °. This interval is usually sufficient to unlock a usual door lock 16. At the end of this rotation zone, however, the outlet bushing 34 reaches a stop and can no longer rotate.

To avoid this disadvantage, it is provided that the connecting rod 33 has an elongated hole 331. This elongated hole 331 makes it possible for the outlet bushing 34 to rotate 180 °. In this regard, the elongated hole 331 may either be disposed at the end of the outlet side, as shown in Figure 3, or be disposed at the end of the sliding side, as depicted in Figure 7 and in Figure 8. If the elongated hole 331 is shown as in Figure 3, in the area of the outlet bushing 34, a bolt 341 of the outlet bushing 34 is housed in the elongated hole 331 so that it can be moved and so that it can rotate. The bolt 341 is located at the end of an eccentric 342, which is connected with protection against rotation with the outlet bushing 34. In this sense it is essential that the clearance between the outlet bushing 34 and connecting rod 33 is greater than the radius of the outlet bushing 34, so as to ensure that the outlet bushing 34 can rotate freely and that the connecting rod 33 does not touch the outlet bushing 34 when rotating. With the corresponding calculation of the length of the eccentric 342 this free space can be adjusted.

In figure 7 and in figure 8 a version of the panic pressure bar 2 is shown without outside slide, that is, in this case it is a mere mechanical variant of the panic pressure bar 2 in which a release of The door lock 16 is made directly by actuating the drive handle 21.

As for the remaining characteristics, especially as regards the outlet bushing 34 that can rotate 180 °, the panic pressure bar 2 shown in Figures 7 and 8 coincides with the configurations described in the previous figures.

By pressing the drive handle 21, in this case it is also actuated, by means of the transmission levers 41, 42, and the slide 31 is moved to the right. This slide 31 is connected, by means of a pin 311, with the connecting rod, and drag it directly. In this way the outlet bushing 34 rotates in the opening direction and unlocks the connected door lock 16.

In the representations of Figure 7 and Figure 8 the elongated hole 331 is disposed at the end of the sliding side of the connecting rod 33. In the elongated hole 331 the pin 331 of the slide 31 is housed. The end of the side of connecting rod bushing 33 is connected to outlet bushing 34 by means of eccentric bolt 341. By means of an eccentric cam 342 the necessary space between bushing housing 34 and connecting rod 33 is adjusted, so that this small space it is enough to rotate the 34180 ° outlet bushing.

In figure 7 a first neutral position of the outlet bushing 34 is shown. In this first neutral position the panic pressure bar 2 can be used for right-mounted doors according to DIN standard. Figure 8 shows the panic pressure bar with the second position of the outlet bushing 34. In this case, the outlet bushing 34 is rotated 180 ° with respect to the first neutral position. With this neutral position the panic pressure bar can be used for doors mounted on the left according to the DIN standard.

It is essential for changeability that in the rotation zone of the outlet bushing 34 and its eccentric 342, no component that hinders the rotation movement engages. The pivot zone of the connecting rod 33 must also not present obstacles.

A change of the panic pressure bar for doors mounted on the left according to DIN norm or on the right according to DIN norm is carried out by introducing, for example, a door latch with a door latch pin in the outlet bushing 34 and correspondingly rotating the outlet bushing 34 by means of the door handle as a handle. Then, the door handle with the door handle is removed from the outlet bushing 34. Then, by means of a conventional pin, the connection to a door lock 16 or to the lock bushing can occur. Thus it is possible to use the panic pressure bar 2, without constructive intervention in the panic pressure bar 2 or without component modifications, for doors mounted both to the right according to the DIN standard and to the left according to the DIN standard.
