Description

The invention relates to a panic bar for actuating a door locking mechanism of a door leaf having a door assembly, with a transmission and with at least one actuating lever having actuating means, wherein at least one illuminated, illuminated and / or colored accentuated intermediate ring between the transmission and the actuating lever is provided.

Panic bars are used as actuators for the opening of doors and serve for a simplified operation of a door locking mechanism of a door, for example in emergency situations. For this reason, the use of panic bars is often provided for escape route doors. By pressing on an almost over the entire door width extending actuator panic bar this is pivoted to the door leaf, which releases the door via a mechanism and thus the opening of the door is enabled. In particular, this allows a larger crowd to quickly leave a danger area in an emergency without the need for a door handle to be operated by an individual.

The above-described, special installation situation for panic bars is often associated with a special labeling in relation to the door function. For example, escape route doors are usually identified by a corresponding signage near the door, by a particular color or a label of the door and / or the panic bar.

However, these forms of labeling are often static and thus can not be adapted or only with relatively great effort to different situations in most cases. In addition, identification forms, such as a paint in a signal color, only passively recognizable by external lighting.

In a panic bar, which serves as an actuator for a door, for example, the opening of escape route doors, the labeling is of particular importance. In an emergency finding an actuator or a corresponding escape door must be guaranteed even under difficult conditions and in poor visibility.

In addition, the adaptation of a corresponding marking in doors, which in addition to a function as an escape route further, especially changing, conditions of use is usually associated with a static form of labeling with considerable effort.

A generic panic bar is already out of the EP 2 708 687 A1 known. The disadvantage is that in the known panic bar safe identification of the panic bar is not guaranteed even in poor visibility conditions.
In addition, from the DE 20 2009 010 889 U1 an electric locking system for an electromechanical panic lock known. The locking system has a horizontally extending over the door width push rod, wherein at least one passively illuminating light source is arranged on the push rod.

Object of the present invention is to provide a way for variable identification of a panic bar for installation on a door, the label should be recognizable even in poor visibility conditions at the installation.

The above object is achieved in a panic bar with the features of the preamble of claim 1, characterized in that the intermediate ring is associated with at least one illuminant having lighting device and / or that the choice of accentuation of the intermediate ring takes place in the form of a signal color. By choosing the color of the accentuation, in the form of a signal color can be achieved either a permanent, eye-catching identification of the panic bar or a subtle visual appearance for better integration of the panic bar in the design of a door assembly. Due to its compact design, the intermediate ring can be well integrated into the mechanics of the panic bar or the actuating means of the panic bar, so that no or little design concessions must be made if a panic bar according to the invention is installed on a door to take into account safety aspects. Depending on the size and shape of the intermediate ring, it is possible, for example, to cover parts of the mechanism of the panic bar by the intermediate ring.
Due to the possibility of illumination of the intermediate ring its signal effect is amplified, or can be a mark in need or emergency on or To turn off, for example, to draw attention to an escape route or to direct large crowds at major events. Additionally, by switching the illumination color and / or brightness, the tag can be dynamically adjusted to a given situation. It is thus possible, for example, to respond in a finely graduated manner to changes in a dangerous situation, which is advantageous in view of the usual use of panic bars in the area of escape routes or on flyway doors. Lighting also makes it possible, even with limited visibility, for example by smoke, to find a correspondingly marked door from a further distance, or to obtain the general orientation ability of persons in the danger zone.

The illumination of the intermediate ring is carried out according to the invention by a lighting device associated with the intermediate ring, which has at least one light source. The intermediate ring is thus exchangeable independently of the illumination device, so that in a simple manner the permanent identification can be changed while the form of the signaling effect achieved by the illumination is maintained. Conversely, it is also possible to change the lighting device regardless of the intermediate ring in each configuration or to replace it with another lighting device. On the one hand, this facilitates the maintenance or repair of the corresponding components. Furthermore, in order to provide panic bars for various installation situations, only individual components have to be adapted or replaced by the aforementioned modular principle without the need for specially manufactured or even newly developed essential, comparatively complex elements of the panic bar, which means the costs for the provision considerably reduced by panic bars adapted to the respective installation situation.

As a lighting means of the lighting device, in particular, a light-emitting diode (LED) is suitable, which is inexpensive and readily available and also characterized by a high robustness and a long service life. In addition, an LED is a comparatively compact lamp. This is especially true for an RGB LED, which has the advantage of high variability for reference to the color and intensity of light in a very compact design. In an RGB LED, three light-emitting diodes are arranged in a common light-emitting body, wherein the three light emitting diodes light in the three primary colors red, green and blue and are independently adjustable in the emission intensity, so zwisehen by the setting of intensity ratios The primary colors according to the principle of additive color mixing can be set to almost any luminous color of the entire light source. Due to the combined arrangement of the three emitters in a lamp body, a lighting device equipped with an RGB LED is just as easy to produce as when it is fitted with an ordinary, single-color LED. However, it is variable with respect to the illumination color and / or brightness.

The aforementioned also applies in a similar form to the use of a color change LED which is significantly less expensive than RGB LEDs and which has only two differently colored light emitters, frequently in the combination of red and green, in a common luminous body. In addition, the use of other light sources as lighting means of the lighting device is conceivable, for example electroluminescent, which are well integrated even in a complex mechanism of the panic bar due to their flexibility and their flat, diffuse light output, or conventional incandescent or glow lamps.

In a preferred embodiment, the lighting device has a circuit board, with which the lighting means is connected. This makes it possible to realize a compact design of the illumination device, wherein the board serves, for example, as a support of a supporting electronics and in particular may have electronic and / or opto-electronic components. With regard to a simple construction of the lighting device, it is also possible that the power supply takes place centrally via the board, from which in turn the one or more bulbs are supplied.

With regard to a compact design of the illumination device, it is particularly preferred to arrange the light source directly on the board. Here, the use of a designed as a surface-mounted device (SMD) bulbs offers, which is characterized by a particularly compact or flat design. In this way, the board serves as a single carrier for the one or more bulbs and possibly the supporting electronics. As a result, a high degree of integration is achieved, which has an overall advantageous effect on the size of the lighting device.

A sufficiently compact design of the illumination device or of the circuit board makes it possible to arrange these in the region of the transmission, preferably within a cover flap surrounding the transmission mechanism. In this position, the lighting device or the board is close to be illuminated Intermediate ring, while inconspicuously integrated into the mechanics of the panic bar and also protected together with the other transmission components of the cap. In addition, a supply line can lead in a manner inconspicuous to the outside via the gear housing to the illumination device. In order to ensure a good illumination of the intermediate ring, the illumination device is positioned so that the light emitted by it is directed to the front-side annular surface of the intermediate ring and preferably enters this perpendicular.

For receiving the illumination device or the circuit board is particularly suitable a bearing block of the transmission, which has a size and stability sufficient for this purpose. The bearing block is usually designed so robust that readily appropriate fastening means, such as threads or hooks, or a special receptacle can be provided on this, to arrange the board frontally on the bearing block without its stability is impaired.

In the case of an arrangement of the illumination device in the region of the transmission, it is particularly preferred that the covering cap for covering the gear mechanism has at least one recess which releases the illumination means of the illumination device. As a result, the greatest possible protection of the illumination device against dust and mechanical damage is achieved. This contributes to ensuring the function of the lighting device over a long life, which is particularly advantageous in an escape route marking. In addition, can be limited by the configuration of the recess, the emission of the illumination device or shade a portion of the light, for example, to counteract glare of the user. In this case, various shapes and sizes of the recess, for example circular, slit-shaped or, in particular, a shape corresponding to the form of the board, can be provided.

For a complete and uniform illumination of the intermediate ring with sufficient intensity, the illumination device can have at least three, preferably at least four, lighting means. In addition, a redundant arrangement of lighting means ensures the function of the lighting device in case of failure of one or more lamps. Such a failure protection additionally increases safety, in particular in the case of an escape route marking.

For a uniform and homogeneous illumination of the intermediate ring, the lighting means are preferably distributed over the circumference of the intermediate ring with the same distance from each other. In this case, the lighting means are arranged so that the emission direction of the light emitted by them is preferably aligned perpendicular to the end-side annular surface of the intermediate ring. Alternatively, however, the lighting means can also be arranged in any desired manner along the circumference of the intermediate ring and at any desired angle relative to the frontal annular surface of the intermediate ring in order, for example, to consciously achieve inhomogeneous illumination of the intermediate ring.

In a preferred embodiment, the intermediate ring has an at least substantially transparent material, so that light entering the intermediate ring can at least largely penetrate it. In this way, the intermediate ring can be illuminated almost homogeneously even with a lighting device arranged on one side.

To scatter the light entering the intermediate ring, particulate suspended matter may be provided in the material of the intermediate ring. Here, in addition to the use of, for example, matte particles on which the light is scattered at least substantially isotropically in the solid angle, it is also conceivable that particles having a reflective surface, for example metal particles and / or luster pigments, are provided. Due to a random orientation of the reflective surfaces of a plurality of such particles, an overall isotropic scattering of the incident light is achieved, whereby a high brilliance of the optical appearance of the intermediate ring is achieved. In addition, the use of other functional, particulate materials, such as fluorescent particles, conceivable as well.

By a corresponding material properties of the intermediate ring, it is possible that this appears in unlit and in the illuminated state in different colors. This can be achieved, for example, by providing coloring pigments and light-scattering particles in the material of the intermediate ring. Light entering through the lateral surface of the intermediate ring during external illumination is then partially absorbed by the pigments, so that the intermediate ring appears in a specific color. In the case of a differently colored illumination by the illumination device in the sense of the invention with sufficient intensity, the perception of the light scattered by the particles overlaps the color impression predetermined by the pigments. A static The shape of the marking can thus be superimposed, if necessary, by the illumination in order to effect a simple change of the marking. Alternatively, the intermediate ring on its outer circumferential surface also have a layer which is such that it partially absorbs light incident from the outside, so that a certain color impression is generated. At the same time, this layer may be at least partially permeable to light emerging from the inside of the intermediate ring from the illumination device.

In a particularly preferred embodiment, the panic bar is associated with a control device which serves to control the illumination of the intermediate ring. The control device may be, for example, a logic circuit having a comparatively simple structure which is arranged within the panic bar according to the invention. However, the control device is preferably programmable, so that can be stored in a simple manner different switching pattern for the illumination of the intermediate ring. Compared to a replacement of components, a reprogramming of the control device is a much simpler and cheaper way to modify the lighting of the intermediate ring.

In particular, it is also possible to arrange the control device outside the panic bar. The external arrangement of the control device also makes it possible to realize more complex solutions associated with increased space requirements for controlling illumination parameters. For example, such a control device via a data line with a central device for controlling the building technology or an alarm system can be connected.

In an arrangement of the control device in the interior of the panic bar, a part of the control device is preferably provided on the circuit board of the illumination device. This compact design of the comparatively complex system of the lighting and the control device contributes to an overall small size of the panic bar. The integration of the two aforementioned devices on a common board reduces the dependence of the system of corresponding connection lines. As a result, the susceptibility is reduced, which is particularly desirable in the identification of escape routes.

The lighting device can also be designed such that a flashing illumination of the intermediate ring is provided. This will be the signal effect of the illuminated intermediate ring, for example in emergency situations, further increased.

By means of an adjustable blinking frequency, it is possible, in particular, to indicate different states of the door and / or of the lighting device, for example for signaling a fault. In addition, it is conceivable, depending on a setting of the blinking frequency, in particular by the control device, to mark the identification of a door as a function of the situation. It is understood that different flashing patterns can also be provided, that is to say that the flashing frequency changes over time.

By the independent control of the illumination parameters for the illumination of the intermediate ring by means of the control device, wherein in particular the color, the intensity and / or the flashing frequency are adjustable, the illumination of the intermediate ring can be adjusted over a wide range. In this case, the control of the illumination parameters is preferably carried out by preset programs. It is also conceivable to control the illumination parameters as a function of external signals, which are supplied to the control device via input channels, whereby a situation-dependent adaptation of the illumination parameters can also take place, for example, automatically.

The coupling of the control device and / or the illumination device with a door locking mechanism makes it possible to detect an actuation of the door locking mechanism and to adapt the illumination parameters for the illumination of the intermediate ring depending therefrom. Such a dependent identifier can, for example, inform about the status of a door, that is to say, for example, "free" or "locked", or indicate that the door has been used. For the purpose of an inflow control, for example, it is also conceivable, for example, to display the door release after a waiting period after use.

By a sensor for detecting an actuation of the Türverrieglungsmechanik not only a direct coupling of the illumination device with the door lock mechanism can be achieved. In addition, it is conceivable for the data of the sensor to be read out or evaluated by the control device and to be reused within the framework of a control program, for example as a function of the number of actuations of the panic bar.

It is also possible to couple the control device and / or the lighting device with a quiescent current opener of a door. By such a quiescent opener, the door is locked as long as a quiescent current flows through which the case of a door opener is held. In the event of a power failure, for example, by the actuation of a push button or in the event of a power failure, the door is released and can be opened. To prevent theft and a subsequent escape through an emergency exit it is usually provided in the case of escape doors in the area of sales areas that sounds an acoustic signal when the emergency button to interrupt the quiescent current for the door opener. By coupling the control device and / or the illumination device with the quiescent current opener of a door, an optical identification by the illumination of the intermediate ring to the acoustic signal or on behalf of this can be done. The coupling with the quiescent current opener can either be formed directly, for example, by a measurement of the quiescent current or indirectly, for example, the signal of the emergency button.

Depending on spatial conditions, which in particular affects the visibility of a room, it is sometimes advantageous or even necessary to support the visual warning effect of a panic bar with a lit, illuminated and / or colored accentuated intermediate ring by further measures. For this purpose, the control device and / or the illumination device can be coupled in particular with an acoustic signal generator.

In order to direct attention to existing escape routes in emergency situations and to direct persons to be evacuated in corresponding directions, in a preferred embodiment the illumination device and / or the control device is coupled to an emergency signal device. If an emergency signal is triggered in an emergency, for example, the color and / or the flashing frequency of the lighting can be changed.

In emergency situations, it is necessary that a signaling effect is ensured even with a defective mains supply. For this purpose, an energy store is preferably provided for a network-independent power supply of the lighting device. The energy storage can be arranged for example inside the panic bar or be present as part of the door assembly.

It is understood that in a panic bar according to the invention also on both sides of the actuating means in each case at least one illuminated, illuminable and / or colored accented intermediate ring can be provided. The redundant presence of such an intermediate ring increases the reliability, which is particularly advantageous in the identification of escape route doors. In addition, a symmetrical arrangement of intermediate rings on a panic bar from a design point of view contributes to a harmonious appearance.

In the course of the overall equipment of a room or a building, a door system is preferably provided which has at least one door arrangement with a panic bar according to the invention. In particular, it is conceivable that a plurality of door arrangements of the aforementioned type form such a door system.

The central control and in particular the combination of a plurality of door arrangements to a door system offers the advantage that concepts for marking, for example, escape routes, or for steering larger groups of people can be implemented uniformly and centrally for the entire door system. The control device can be coupled to a plurality of door assemblies. However, the individual door arrangements can also be controlled independently of each other.

A central control of the door identification makes it possible, for example, to respond dynamically to a change in the dangerous situation and to direct people away from dangerous areas. In addition, information about the movement behavior of persons or groups of persons can be obtained and evaluated by the central detection of the data of sensors for actuating the door locking mechanism of the individual door arrangements of a door system to make a corresponding adaptation of the labeling of door assemblies of the door system by changing lighting parameters. In this way, not only in emergency situations, but also, for example, in large events, streams of people can be divided and directed accordingly. A changeable, colored identification of a door, in conjunction with the door locking mechanism, indicates the status of the door as "locked" or "released", for example. In an emergency, all doors would be released by the controller and could be used as escape routes.

The central control of the lighting devices on a plurality of door arrangements of a door system, in particular with respect to the color, the intensity and / or the flashing frequency, by a coupled to the building control system of a building control device can be an illuminated intermediate ring, and in particular Integrate a plurality of lighted intermediate rings, in a total lighting concept. The intermediate ring and / or the illumination device is preferably designed such that at least a substantial part of the light of the illumination device or; the intermediate ring directly illuminates part of the door assembly.

Other features, advantages and applications of the present invention will become apparent from the following description of embodiments with reference to the drawings and the drawing itself. In this case, all descriptive and / or illustrated features alone or in any combination, the subject of the present invention, regardless of their Summary in the claims or their dependency.

Fig. 1 shows a panic bar 1 in the installed state on a door leaf 2 having door assembly 3 in a perspective schematic representation. The panic bar 1 has an actuating means 4, which in the present case extends almost over the entire width of the door leaf 2. The actuating means 4 is designed in several parts and has a handle bar 5 and on both sides of the handle bar 5 each have an end arranged on the handle bar 5 actuating lever 6 which is pivotally mounted at its end remote from the handle bar 5. When actuated by a pressure on the handle bar 5, the actuating means 4 thereby performs a pivoting movement to the door leaf 2 out. The actuating lever 6 is movably connected to the belt side by means of an axis, not shown, with a bearing device 7. For lock-side storage is a transmission. 8 provided, which serves to transmit a torque generated by an actuation of the actuating means 4 on a door lock mechanism.

The transmission-side portion of the panic bar 1 is in Fig. 2 shown schematically in frontal view. While it is conceivable in principle to form the actuating means 4 in one piece, the handle bar 5 and the actuating lever 6, as shown here, are present as separate components, which together form the actuating means 4.

The actuating lever 6 is spaced from the transmission 8 perpendicular to its pivot plane. In the intermediate space between the actuating lever 6 and the gear 8, an intermediate ring 9 is presently provided.

The intermediate ring 9 is formed such that its outer diameter corresponds to the outer dimensions of the adjacent region of the actuating lever 6, whereby an overall harmonious alignment is achieved in the installed state. To connect the intermediate ring 9 with the actuating lever 6 and in particular for the radial fixation of the intermediate ring 9, the intermediate ring 9 on the actuating lever 6 side facing a circumferential shoulder, so that there is a portion of the intermediate ring 9 with a smaller outer diameter. With this section, the intermediate ring 9 engages in a corresponding receptacle on the actuating lever 6 a. Although the aforementioned, one-sided connection of the intermediate ring 9 with the actuating lever 6 is sufficient for a radial fixation of the intermediate ring 9, it is conceivable that a corresponding connection is also provided on the transmission side.

The intermediate ring 9 may have an at least partially transparent material and / or be accentuated in color. By means of a lighting device, not shown, the intermediate ring 9 can be illuminated. The light of the illumination device passes through the transparent material of the intermediate ring 9 and is scattered on particulate suspended matter, which may be provided in the transparent material of the intermediate ring 9, so that the intermediate ring 9 appears outwardly in the illumination color.

The mechanical components of the transmission 8 are concealed in the present illustration by a cap 10. The compact embodiment of the transmission 8 makes it possible to limit the outer dimensions of the transmission 8 such that a non-constraining pivoting of the door panel 2 allows for a door opening becomes. For this purpose, the cap 10 on the side facing away from the actuating lever 6 on a chamfer, through which a corresponding space is created.

One possible form of beveling of the cap 10 is by the in the in Fig. 3 shown top view of in Fig. 2 illustrated range of the panic bar 1 illustrates. In this perspective, a protruding from the gear 8 in the direction of the door panel 2 square receptacle 11 is also recognizable. This engages in the door lock mechanism and is connected there by means of a square bolt, not shown, with a lock nut of the lock mechanism of the door assembly 3.

The handle bar 5 and the operating lever 6 are connected by a fastening means 12. For optical reasons, the fastening means 12 is arranged on the underside of the panic bar 1, as in the in Fig. 4 shown bottom view of the transmission-side portion of the panic bar 1 is shown. Similarly, a bolt 13 is arranged on the underside, which connects the actuating lever 6 positively with an internal shaft, which serves to transmit a torque from the actuating lever 6 to the transmission 8.

The in the Fig. 6 to 9 shown views of the transmission side portion of the panic bar 1 correspond in the representation of those in the Fig. 2 to 5 , wherein the representation of the intermediate ring 9 and the cap 14 has been omitted, so that the transmission mechanism is recognizable.

An essential component of the transmission 8 is a bearing block 13, the upper side, that is on its side facing away from the door leaf 2, a reinforcing region 15 has. The gain region 15 is extended so far that it covers other components of the transmission 8. Furthermore, the bearing block 14 has openings 16 for the passage of connecting means, in particular screws, for connection to the door leaf 2 or arranged in the door leaf 2 door locking mechanism.

Further, frictional engagement elements 17 are provided on the bearing block 14 for the formation of a frictional connection of the bearing block 14 with the cap 10, wherein the frictional engagement elements 17 are formed in the present case as a rubber buffer. Alternatively, it is conceivable to effect locking connection of the bearing block 14 with the cover cap 10 by means of latching elements.

The bearing block 14 serves to support a shaft 18 connected to the actuating lever 6, wherein a drive piece 19 is provided on the end of the shaft 18 facing away from the actuating lever 6. The drive piece 19 has a cam 20, by means of which the drive piece 19 is connected via a cam 21 of the square socket 11 with this in operative connection.

Between the actuating lever 6 and the bearing block 14, a return spring 22 is provided which serves the return movement of the actuating means 4 in an initial position after actuation. The return spring 22 is concealed in the installed state of the panic bar 1 from the intermediate ring 9. In the present case, the return spring 22 is designed as a helical spring. This compact design, it is possible to integrate the return spring 22 outside of the transmission 8 in an inconspicuous manner in the mechanics of the panic bar 1, in which the return spring 22 is arranged such that it is arranged around the shaft 18, wherein the spring axis coaxial or runs parallel to the shaft longitudinal axis.

To limit the rotational movement range of the square mount 11 a stop means 23 is provided on the bearing block 14, as in the in Fig. 7 shown top view of the transmission side portion of the panic bar 1 is shown. In the present case, the stop means 23 is a threaded pin, which in particular allows stepless adjustment of the limitation of the rotational movement range of the square receptacle 11.

As in the perspective views in FIGS. 9 and 10 as well as the side view in Fig. 11 is shown, the shaft 18 at its gear-side end a polygonal structure, in the present case in the form of an octagon, to form a positive connection with the drive piece 19. It is also conceivable, for example, a connection by means of a bolt.

The drive piece 19 engages with a cam 20 on a cam 21 of the square socket 11, so that the drive piece 19 is operatively connected to the square socket 11 in this way. The square mount 11 is rotatably mounted in a receptacle of a base plate 24. A rotation of the shaft 18 and thus of the drive piece 19 thus ultimately causes a rotational movement of the square holder 11. The square holder 11 is performed so precisely due to the storage in their movement that a tilting, which would have a possible obstruction of an opening of the door result, successful counteracted.

The bearing block 14 also has a passage opening 25 which can serve, for example, the passage of a cable for supplying energy to a lighting device, not shown, for illuminating the intermediate ring 9.

By dispensing with the representation of the return spring 22 in Fig. 10 the shaft 18 in the area between the actuating lever 6 and the bearing block 14 can be seen. On the shaft 18, a flange 26 is provided in this area, which has at least one opening 27. The opening 27 serves to receive an end leg 28 of the return spring 22nd

Especially in the Fig. 12 shown rear view of the transmission-side area of the panic bar 1 base plate 24 can be seen. The base plate 24 is connected to the bearing block 14 preferably by a screw connection. The unit of the bearing block 14 and the base plate 24 can then be connected to the door leaf 2 or arranged in the door leaf 2 door locking mechanism. For this purpose, 14 openings 16 for the implementation of fasteners, such as screws, are provided in the bearing block.

The square mount 11 is rotatably mounted in the base plate 24. For this purpose, the base plate 24 has a corresponding bearing opening 29.

Fig. 13 shows in a representation as an exploded view of the components of a preferred embodiment of a transmission arrangement according to the invention and the transmission-side part of the actuating means 4. The actuating means 4 is present in several parts. The handle bar 5 is connected via a connecting means 30 and an intermediate piece 31 with the actuating lever 6. The connecting means 30 engages in the handle bar 5 and the actuating lever 6, wherein it is fixed by a fastening means 12 in the actuating lever 6. By engaging the connecting means 30 in a corresponding receptacle of the handle bar 5, the handle bar 5 is held, with a corresponding connection of the handle bar 5 is provided with the actuating lever 6 via a connecting means 30 and an intermediate piece 31 also on the door-side end of the handle bar 5.

At the handle bar 5 remote from the end of the actuating lever 6, the actuating lever 6 has a receiving opening 32 for receiving the shaft 18. The shaft 18 is by means of a bolt 13 or other positive locking element with the actuating lever 13 positively connected. Through this connection, a torque is transmitted to the shaft 18 upon actuation of the actuating means 4 and associated pivotal movement of the actuating lever 6.

For return movement of the mechanism after actuation of the actuating means 4, a return spring 22 is provided, which is in the present case designed as a helical spring. The return spring 22 is arranged surrounding the shaft 18, wherein the spring axis runs parallel to the shaft longitudinal axis- Thus, the return spring 22 can save space outside the gear 8 order. The return spring 22 in this case has an end leg 28 facing the actuating lever and an end leg 33 facing the gear, the end legs 28, 33 each extending parallel to the spring axis.

To accommodate the actuating lever facing end leg 28 of the return spring 22, the shaft 18 has a flange 26 with at least one opening 27. The end leg 28 of the return spring 22 engages in the opening 27 of the flange 26 a. The opening 27 thus represents the operating lever side starting point for the force exerted by the return spring 22 restoring force. The flange 26 may further comprise at least one further opening 27 so that, for example, by a symmetrical arrangement of the openings 27 on the flange 26 such a design of the shaft 18th is suitable for the installation of a panic bar 1 on a door assembly 3 both with a left-hinged door leaf 2 and with a right-hinged door leaf 2.

The transmission-side end leg 33 of the return spring 22 engages in a in the FIGS. 15 and 16 illustrated receiving opening 44 of the bearing block 14, which thus represents the gear-side approach point for the force exerted by the return spring 22 restoring force for return movement of the actuating means 4 in the starting position after actuation of the panic bar 1.

With regard to a rotatable mounting, the shaft 18 preferably has at least substantially a round profile. On the transmission-side end, however, a polygonal structure, which engages in the drive piece 19 to form a positive connection, provided.

In the present case, the shaft 18 is guided through a bearing sleeve 34, wherein the bearing sleeve 34 surrounds the shaft 18 in a bearing region 35. The bearing sleeve 34 is preferably designed as a hollow cylinder, which has a circular profile outside and inside. On the bearing sleeve 34, a stopper 36 is also provided. The stop 36 is presently designed as a circumferential collar, but it is also conceivable a segmented embodiment or a stop 36 in the form of individual, projecting from the bearing sleeve 34 extensions.

For supporting the shaft 18, the bearing block 14 has a bearing wall 37 with a preferably designed as a circular opening bearing opening 38. The bearing sleeve 34 passes through the bearing opening 38, wherein the stop 36 serves for external contact with the bearing wall 37. The bearing sleeve 34 is significantly longer in the shaft longitudinal direction than the relatively small material having bearing wall 37. Thus, the bearing sleeve 34 prevents long-term damage or wear of the shaft 18 in the bearing area 35 and / or the bearing wall 37 in the bearing opening 38th

The comparatively low material thickness of the bearing wall 37 makes a further reinforcement of the bearing block 14 necessary for stabilizing against the occurring bearing forces or torques. For this purpose, a reinforcing region 15 is provided on the bearing block 14 on the upper side, that is to say on the side facing away from the door leaf 2. This extends transversely to the shaft longitudinal axis preferably almost over the entire bearing block 14 and is preferably extended in the longitudinal direction by a multiple greater than the thickness of the bearing wall 37 in the longitudinal direction.

A pivoting movement of the actuating lever 6 as a result of actuation of the actuating means 4 via the shaft 18 to a rotary movement of the drive member 19 which is about its own cam 20 and a cam 21 of the square holder 11 in operative connection with this, that a rotational movement of the square holder 11th he follows. The square mount 11 is rotatably mounted in a bearing opening 29 in the base plate 24. The bearing opening 29 need not be completely surrounded by material of the base plate 24, but may for example be open to one side to save in this way further space requirements and to support a compact design of the transmission 8. The base plate 24 also has at least one opening 39 for the passage of a fastening means, in particular a screw, for fastening the plate 24 on the bearing block 14.

To limit the rotational movement range of the square receptacle 11, a stop means 23 is provided, which is inserted into the bearing block 14. Preferably, the stop means 23 is adjustable. For example, a stop means 23 in the form of a threaded pin permits a continuous adjustment of the limitation of the movement range of the square receptacle 11.

In order to prevent jamming of the square mount 11 during a rotational movement as a result of actuation of the panic bar 1 via the actuating means 4 and jamming of the door locking mechanism connected to the tilting of the square socket 11, it is necessary to precisely guide the square mount 11 in its rotary movement. For this purpose, as in Fig. 14 recognizable, provided between the base plate 24 and the bearing block 14, a receptacle 42 in which the square holder 11 is caught rotatably. The precise guidance through the bearing receptacle 29 of the base plate 24 and the receptacle 42 reduces the degrees of freedom of movement of the square receptacle 11 such that only one rotation of the square receptacle 11 is possible, whereby the risk of tilting is minimized.

To protect the gear mechanism and optical reasons, the gear 8 is associated with a cap 10 which is held by a frictional connection by means of at least one frictional engagement element 17, wherein in the present case a plurality of Reibschlusselementen 17 is provided in the form of rubber buffers.

The region of the return spring 22 arranged outside the transmission 8 is surrounded by an intermediate ring 9 for similar reasons. In addition, it is conceivable to illuminate the intermediate ring 9 by means of a lighting device.

The illumination device in this case has a circuit board 40, which is arranged on the bearing block 14 on the actuating lever 6 facing the end face and at least one illuminating means 41 of the illumination device. The light source 41 is arranged aligned on the circuit board 40 to the intermediate ring 9, so that the main emission of the light of the light source 41 is preferably parallel to the longitudinal axis and the light enters the end surface in the annular surface of the intermediate ring 9.

For illuminating the intermediate ring 9, a plurality of lighting means is preferably provided on the circuit board 40. These are at least substantially uniformly distributed over the circumference of the intermediate ring 9 to a homogeneous To ensure illumination of the intermediate ring 9. The FIGS. 15 and 16 show in a view from the direction of the actuating lever 6 and the intermediate ring 9 schematically each have a transmission arrangement according to the invention, wherein different embodiments of the circuit board 40 of the illumination device with respect to the arrangement of lamps 41 are shown. At the in Fig. 15 In the illustrated embodiment, the circuit board 40 of the illumination device has three light sources 41 in the form of light-emitting diodes, while in the case of the light source in FIG Fig. 16 illustrated embodiment four bulbs 41, also in the form of light-emitting diodes, are provided. It is understood that any other number or type of lighting means can be provided. In particular, RGB LEDs are preferably used as lighting means, since they allow a different color lighting of the intermediate ring 9 in a simple manner and in a compact design.

The circuit board 40 is preferably disposed within the cap 10, so that it, like the mechanics of the transmission 8, protected by the cap 10 and is covered. In order not to obstruct the light radiated by the lighting means 41 on the way to the intermediate ring 9 to be illuminated, the covering cap 10 has at least one recess 43 associated with the circuit board 40 and / or the lighting means 41. In the present case, the recess 43 is formed such that the circuit board 40 is substantially exposed on the side facing the intermediate ring 9, that is to say in the emission direction of the lighting means 41. However, it is also conceivable, for example, an embodiment in which the cap 10 has only recesses 43 at the positions of the lamps 41. <B> LIST OF REFERENCES: </ b> 1 panic bar 23 slings 2 door leaf 24 baseplate 3 door assembly 25 Through opening 4 actuating means 26 flange 5 Grab bars 27 opening 6 actuating lever 28 end leg 7 bearing device 29 bearing opening 8th transmission 30 connecting means 9 intermediate ring 31 connecting piece 10 cap 32 receiving opening 11 Square drive 33 end leg 12 fastener 34 bearing sleeve 13 bolt 35 storage area 14 bearing block 36 attack 15 gain range 37 bearing wall 16 opening 38 bearing opening 17 frictional engagement 39 opening 18 wave 40 circuit board 19 drive piece 41 Lamp 20 cam 42 admission 21 cam 43 recess 22 Return spring 44 receiving opening
