The invention relates to a transmission for a panic bar or a panic bar with

• a base element which has a fastening plane for bearing against a door, in particular on the frame of a door,
• a rotatably mounted in a guide sleeve of the base member square seat, the rotational and longitudinal axis extending perpendicular to the mounting plane,
• a coupling element for connection to a panic grip or a panic bar,
  and
• Transmission elements for the implementation of a fastening plane directed towards the movement component of the coupling element in a rotary motion of the square socket.

Panic handles and panic bars are known from the prior art in different embodiments and are characterized in that an actuating element extends virtually over the entire width of a door, wherein a movement of the actuating element in the direction of the door to open a door lock provided in the door leads. The actuating element can be designed, for example, as a rod articulated via two end-side levers, which can be moved by means of a pivoting movement in the direction of a door leaf. Alternatively, it is also possible to form the actuating element as a pressure bar, which can be moved over a substantially linear movement in the direction of a door leaf.

In all embodiments of known panic attacks and panic bars, it is necessary to implement the explained movement of the actuating element in a rotational movement of a square receptacle, since this rotational movement ultimately leads to an opening of the lock via a square held in the receptacle, coupled with a door lock square. In order to realize this movement implementation, a suitable transmission is regularly provided in conjunction with panic attacks and panic bars, which may have, for example, the components mentioned above.

A disadvantage of these known transmissions is the fact that they are available only in comparatively large-volume embodiments, which in certain installation situations can lead to such a transmission or its housing when the door is opened on an adjacent door leaf or on one or a door frame or window frame surrounding the door to be opened abuts, which ultimately prevents or even prevents the desired opening. In particular, panic doors such obstruction of the door opening course must be avoided.

In addition, recently doors with very narrow, surrounding the door panel frame elements are increasingly used. Since when mounting a transmission for a panic bar or a panic bar the square mount must always be located above the frame element, since there is also the lock nut, it is inevitable when using narrow frame that the transmission for the panic grip or the Panic bar including its housing must be mounted very close to the outer periphery of the door, which additionally increases the risk of obstruction when opening the door. Consequently In principle, it is desirable to make transmission for panic handles and panic bars smaller the closer they are mounted in the area of the outer circumference of a door.

A disadvantage of the known from the prior art transmissions is consequently the fact that their volume and thus also the respectively required housing is dimensioned so large that a disability-free opening a panic door, especially in panic doors with narrow frame, can not be ensured.

An object of the invention is to provide a transmission of the type mentioned above, which allows easy opening a panic door in any installation situation, can be used in particular for doors with very narrow frame and at the same time can meet all the usual aesthetic requirements.

This object is achieved by the features of claim 1 and in particular in that the guide sleeve, the coupling element and the transmission elements are arranged on one side of a boundary plane extending perpendicular to the mounting plane and whose distance from the axis of rotation of the square recording less than 15 mm is.

While the components of known from the prior art transmissions are usually arranged around the square mount around that they extend approximately equidistant on both sides of the square drive with mounted gear in the horizontal direction, is now proposed according to the invention, the transmission components asymmetrically and substantially only on to arrange a side of the square socket, so that when mounted according to the invention Transmission all gear components above and below the guide sleeve of the square and in addition only on one side, especially the inside, the square mount come to rest. On the outside of the square, so on that side into which the actuator or the handle bar of the panic bar does not extend, no or only relatively small components of the transmission are provided so that the extension of the transmission, starting from the axis of rotation of the square recording to the outside is minimized. So it is possible with a transmission according to the invention to arrange this at a greater distance to the outer periphery of the door as a trained substantially symmetrical to the square drive transmission according to the prior art. This inventively enlarged distance ensures that a panic door in any installation situation can be opened easily and without disabilities.

It is preferred if the distance between said boundary plane and the axis of rotation of the square recordings is less than 12 mm, preferably between 7 mm and 12 mm and further preferably between 9 mm and 10 mm. It is particularly advantageous if the boundary plane is arranged so close to the axis of rotation of the square socket that it cuts or touches the guide sleeve of the square socket. Through these measures, an absolutely problem-free opening of panic doors is then ensured even in extremely cramped installation situations.

In addition to the guide sleeve, the coupling element and the transmission elements and the complete base element can be arranged on the same side of the boundary plane as the components mentioned. In this case, then beyond the border plane are no components, so that a housing surrounding the transmission on the actuating element or the panic bar or the panic attack facing away outer side may have a side wall which is located at a minimum distance from the axis of rotation of the square socket.

The transmission according to the invention can be implemented particularly advantageously if the coupling element can be pivoted about an axis of rotation running parallel to the fastening plane. When mounted gear, this axis of rotation then extends in the horizontal direction.

After the invention is achieved that the lateral extent of the transmission is minimized in the direction of the remote from the actuator or the panic bar or the panic attack outside, in a preferred embodiment of the invention also also a very low overall height of the transmission can be achieved by the distance between the axis of rotation of the coupling element and the mounting plane is at most 10 mm, preferably less than 8 mm and in particular between 3 mm and 6 mm. This small distance between the axis of rotation of the coupling element and fastening plane makes it possible to minimize the dimensions of the transmission in the direction of the axis of rotation of the square socket.

It is particularly preferred if the axis of rotation of the coupling element is in the mounted state of the transmission above the square socket. Alternatively, it would also be possible to provide this axis of rotation below the square socket.

The coupling element can be stored in or on the base member in any way. For example, it is possible to provide the coupling element with a shaft which is rotatably mounted in a cylindrical recess of the base member. Likewise, it is also possible to provide the coupling element with two fork extensions, each on sit on a portion of a bearing pin fixed in the base element. This embodiment has the advantage that the axis of rotation of the coupling element can be moved very close to the mounting plane, which in turn reduces the overall height of the transmission in an advantageous manner. In the latter embodiment, it is possible to provide in the base member a single pivot pin which protrudes slightly from the base member on two opposite sides, so that the fork extensions of the coupling member can be placed on these two protruding portions. When using the aforementioned fork extensions, it must be ensured that the coupling element does not detach from the base element. For this purpose, the coupling element can be provided, for example, with an arcuate groove which extends in a circle around the bearing journal of the base element and into which engages a fixing pin coupled to the base element.

The transmission elements for implementing a movement of the coupling element in a rotational movement of the square socket can be formed on the one hand as a sliding surface provided on the coupling element and on the other hand as perpendicular to the longitudinal axis of the square recording extending, standing in operative connection with the sliding surface extension. In this case, the sliding surface and the extension can provide simple, in the context of the description of the figures, explained in more detail for the said movement conversion.

The coupling element is preferably movable against a spring force from a basic position into an actuating position. This spring force ensures that the panic bar or the panic bar is automatically moved back to its normal position after his or her actuation, from which he can be operated again. The the coupling element in its basic position acting spring can be formed as clamped between the base member and coupling element compression spring. However, other spring arrangements are also possible.

The distance traveled by the coupling element between the basic and the actuated position swivel angle is preferably adjustable by means of an adjustable stop. Thus, it can be ensured for each lock type cooperating with the transmission according to the invention that the maximum allowable angle of rotation for the respective lock is not exceeded in order thus to ensure that no damage occurs to the lock. The provision of different gears for different types of lock is advantageously not necessary in this preferred embodiment of the invention.

The abovementioned abutment can be designed as an adjusting screw held in the coupling element and cooperating with a stop surface provided on the base element. By screwing such a screw into a thread formed in the coupling element then, for example, the pivot angle of the coupling element can be reduced.

Adjusting screw and compression spring can be located on opposite sides of the square socket, which simplifies the construction of the transmission according to the invention.

The coupling element preferably has an extension extending parallel to its axis of rotation for connection to a panic bar, so that movement of the panic bar can be transmitted directly to the coupling element.

For optical reasons, it is regularly desirable to provide the transmission according to the invention with a housing which is suitable for receiving the base element, guide sleeve, parts of the coupling element and transmission elements. As a rule, only the extension for connecting the coupling element with the panic bar protrudes from the housing.

The housing can be made slightly larger than necessary, so that it can be moved relative to the gearbox or its base element and fixed to the door at a desired position. As a result, the overall arrangement can be optimized both functionally and optically. In particular, the housing is displaceable parallel to the axis of rotation of the coupling element and can be fixed to correspondingly different positions of the door.

The invention extends not only to a transmission for a panic attack or a panic bar, but also to complete panic attacks and panic bars, which are equipped with a transmission according to the invention.

Further preferred embodiments of the invention are described in the subclaims.

1 shows a panic bar 14 mounted on a door 10, shown only in sections, with a narrow frame 12, which actuates a transmission concealed by a housing 16. The door 10 adjoins a door frame, a frame, a second door leaf or a wall 18, in which a not shown lock plate for locking the door 10 is located.

When the door 10 is opened by an actuation of the panic bar 14, the door 10 is pivoted in the direction of the arrow, which results in the area of the outside of the housing 16 facing away from the frame 12 (shown hatched in FIG. 1) at a corner region of the wall 18 (FIG. also hatched in Fig. 1) abuts and thereby a further opening movement of the door 10 or prevents.

This problem is inventively eliminated in that the volume of the housing 16 can be reduced due to a reduced transmission, in particular, the distance between the outside of the housing 16 and the wall 18 is to be increased. At the same time, it should be ensured that the overall height of the housing 16, that is to say its extent perpendicular to the plane of the door 10, does not become larger but as small as possible.

Figures 2 to 5 show a possible embodiment of a transmission according to the invention in the above-mentioned views.

The transmission has an elongate base member 20 which is provided with holes 22, via which it is attached to a door frame can be screwed. At its bottom, the base member 20 has a mounting plane 24, with which it rests in the mounted state on a door or a door frame.

As a part of the same, a guide sleeve 26 for a square receptacle 28 is formed on the base element 20. The square receptacle 28 is rotatably mounted in the guide sleeve 26 about an axis perpendicular to the mounting plane 24 extending axis.

In the assembled state above the square receiver 28, a shaft 30 is guided parallel to the fastening plane 24 through the base element 20, which is part of a coupling element 32 and represents the axis of rotation of this coupling element 32.

The pivotable about the shaft or rotation axis 30 coupling element 32 is provided with an extension 34 which extends parallel to the shaft 30. This extension 34 serves to connect the coupling element 22 with a panic bar 14. The extension 34 has the shape of a square, which can be inserted into a corresponding, frontally provided on the panic bar 14 square recess, so a rigid connection between panic bar 14 and coupling element 32nd manufacture.

The square receptacle 28, which has on its underside 36 a not visible from the figures receptacle for the square of a lock is penetrated in its upper end by a pin-shaped extension 38 which is perpendicular to the axis of rotation of the square receptacle 28 and facing the coupling element 32 Side of the square receptacle 28 protrudes beyond the circumference. The extension 38 lies with its outer circumference on a sliding surface 40 of the coupling element 32.

Perpendicular to the mounting plane 24 extends as part of the base member 20, a web 42 upwards, which ultimately ends in a parallel to the mounting plane 24 extending tab 44. Opposite the tab 44, a tab 46 is also formed on the coupling element 32, wherein between the two together with the coupling element 32 to each other pivotable tabs 44, 46, a compression spring 48 is held.

Based on the axis of rotation 30 on the side facing away from the tab 46 of the coupling element 32, a thread is formed in the coupling element 32, in which an adjusting screw 50 is screwed. The lower end of the adjusting screw 50 is positioned such that it can abut against a stop surface 52 of the base member 20.

2a, 3a, 4a and 5a show that all components of the transmission according to the invention described above are arranged on one side of a boundary plane 54, wherein the boundary plane 54 extends parallel to the axis of rotation of the square socket 28, that is perpendicular to the plane of the latter figures , The distance of the boundary plane 54 from the axis of rotation of the square receptacle 28 corresponds to the radius of the square receptacle 28 in its upper end region. On the side facing away from the square socket 28 of the boundary plane 54 no gear parts are present, so that the transmission has the smallest possible dimensions in this direction. In this way, for example, a size of the housing 16 shown in dashed lines in FIG. 1 can be realized, which does not collide with the wall 18 when the door 10 is opened.

In the basic position of the transmission according to the invention shown in FIGS. 2 and 3, the compression spring 28 is only slightly biased so that it is securely held between the two tabs 44 and 46. Based on this state of the compression spring 48, it is even more compressible. In the basic position - as well as in all operating positions of the transmission according to the invention - the projection 38 abuts against the sliding surface 40, wherein the extension 38 extends obliquely upward in the assembled state of the transmission in the basic position (see FIGS. 2a and 3a).

Upon actuation of the panic bar 14 in the arrow direction (see FIG. 2b), it is pivoted about the axis of rotation 30 of the coupling element 32 in the direction of the arrow. Due to the rigid coupling of the panic bar 14 with the coupling element 32 via the extension 34, the coupling element 32 completes this pivoting movement over an identical angular range.

During this pivoting movement thus also the sliding surface 40 of the coupling member 32 moves around the rotation axis 30 around down, taking with it the projection 38 of the square socket 28 resting against it. During this movement, the extension 38 slides along the sliding surface 40. This ultimately leads to the square seat 28 moves by the said action of the extension 38 from its position according to FIGS. 2a and 3a in a clockwise direction in its position according to FIGS. 4a and 5a. The position shown in Figs. 4a and 5a corresponds to the operating position of the transmission according to the invention, in which the extension 38 now extends obliquely downwards.

By said rotation of the square receptacle 28 is also not shown in the figures, held in the square receptacle 28 Square twisted, which leads to an opening of the connected with the square lock.

During the movement of the coupling element 32 from the basic position into the actuating position, the compression spring 48 is compressed, as can be seen from FIGS. 4b and 5b.

The movement of the coupling element 32 into its actuating position is ultimately stopped by the fact that the lower end of the adjusting screw 50 abuts the stop surface 52 (see Fig. 5b). From Fig. 5b is readily apparent that, for example, a more screwed into the thread of the coupling element 32 screw 50 would lead to a reduction of the pivot angle of the coupling element 32.

After releasing the panic bar 14, this is moved together with the connected coupling element 32 by the restoring force of the compression spring 48 back to its normal position shown in FIG. 2 and 3, so that starting from this basic position a re-actuation is possible.

FIGS. 6a to 6c show illustrations which substantially correspond to FIGS. 2a to 2c but without panic bar 14, FIGS. 6a to 6c now showing an alternative embodiment of the transmission according to the invention.

Also, this alternative embodiment has a majority of the components already explained above, so that will not be discussed in more detail, but only the differences from the transmission according to FIGS. 2 to 5 will be explained.

The fundamental difference between the two embodiments is the mounting of the respective coupling element 32, 32 '. The coupling element 32 'according to FIG. 6 has no shaft 30 integrally formed thereon, but instead has a fork extension 56 at its end facing the fastening plane 24 which rests on a bearing pin 58 which extends parallel to the fastening plane 24 through the base element 20' , In this case, the bearing pin 58 is arranged as close as possible to the mounting plane 24.

Opposite the fork extension 56, the coupling element 32 'is provided with a web 60, the length of which approximately corresponds to the width of the base element 20' and which extends parallel to the mounting plane 24, so that it ultimately engages over the base element 20 '. At the end of the web 60 facing away from the fork extension 56, an extension 62 (see FIG. 6c) is provided, which extends in the direction of the fastening plane 24 and at its lower end likewise has a fork extension 64, which is aligned with the fork extension 56 that it can sit on the other end of the bearing pin 58 extending through the entire base element 20 '.

Due to this arrangement, the coupling element 32 'with web 60 and extension 62 is stably supported on the base element 20', wherein it can be pivoted about the bearing pin 58.

In order to prevent lifting of the coupling element 32 'from the bearing pin 58, two arcuate recesses 66 are provided in the coupling element 32' and in the extension 62, in which a fixing pin 68 protrudes, which is firmly anchored in the base member 20 'and parallel to the bearing pin 58th extends.

In contrast to the embodiment according to FIGS. 2 to 5, according to FIG. 6 it is achieved that the axis of rotation of the coupling element 32 'can be moved even closer to the fastening plane 24, so that the overall height of the transmission perpendicular to the fastening plane 24 can be further reduced ,
