Description

The present invention relates to a Türbetätigeranordnung for moving a door leaf. In particular, a damping of the door leaf is provided in the end position.

Door operator assemblies typically include a door actuator configured as a door operator, door closer or power door closer, a guide rail having a moving member (also called a slider guided in a slide rail), and a lever connecting the door operator and the moving member. The door operator is either fixed to the wall or frame or attached directly to the door. If the door operator is located on the door leaf by way of example, the force is transmitted from the output shaft of the door operator via the lever to the movement element. The moving element is guided linearly movable in the guide rail, which is fixed to the wall or frame. In order to dampen the movement of the moving element and thus also the movement of the door leaf in the end position, a buffer is usually provided on or in the guide rail. The movement element runs on this buffer in the end position.

It is an object of the present invention to provide a door actuator assembly that is very small in cost-effective production and assembly and allows effective damping of the movement of the moving element and thus also the door leaf. In particular, the guide rail and / or the door operator should be integrable or retractable into the frame of a door or in the frame of a door leaf. Furthermore, it is preferred that in the closed state of the door leaf neither the guide rail nor the door operator are visible to the user.

The object is achieved by the features of claim 1. The dependent claims have preferred developments of the invention the subject.

Thus, the object is achieved by a Türbetätigeranordnung for moving a door leaf comprising a longitudinally extending guide rail with at least one guide channel. In particular, two opposite guide channels are provided. Guided in the guide rail elements are guided by a positive reception in the guide channel. As a result, the elements are movable only in the longitudinal direction and can not be removed from the guide rail in any of the other directions. Furthermore, a linearly movably guided in the guide channel movement element and a door operator are provided with an output shaft. The door operator is in particular a door closer. In a preferred arrangement, the door operator is let into the frame of a door leaf. In a corresponding manner, the guide rail is in the frame of the door. Furthermore, the arrangement comprises a lever which is non-rotatably connected to the output shaft and rotatably connected to the movement element, and a guided in the guide channel and fixed relative to the guide rail cap. The cap is guided linearly movable in the guide channel and can thus be brought to the desired position during assembly. At this position, the cap is fixed in the guide rail so that it is no longer linearly movable. As a buffer, a loose received in the cavity between the cap and the guide rail damping element is used. The damping element is simple and is held by the cap at a certain position in the guide rail. Between the damping element and the cap is enough space so that the damping element can expand. The damping element consists in particular of cellular Vulkollan. Furthermore, a linearly movably guided in the guide channel shock element between the damping element and the moving element is provided. About this push element in the end position of the door leaf, the force is transmitted from the moving element to the damping element, so that the movement of the moving element is damped. Depending on the weight of the door leaf, the damping element has a certain size and mass. If you want to build a very narrow guide rail, to integrate them, for example, in the frame of the door or the door, so you have to form the damping element is relatively long and narrow, so that it fits into the guide rail. A simple enlargement, in particular elongation, of the damping or buffer elements in the conventional constructions always leads to the attenuation element buckling and buckling when the motion element strikes the damping element. As a result, the cap is provided according to the invention. The cap is preferably made of sturdy sheet metal or plastic and fixes the position of the damping element. The push member does not press on the cap but on the damping element and thus deforms the damping element within the cap or in the cavity between the cap and guide rail.

It is preferably provided that the impact element engages partially in the cavity between the cap and the guide rail. The damping element is thus located completely in the cavity and does not project beyond the cap. This ensures that the damping element is only deformed in the cavity.

Furthermore, it is advantageously provided that the damping element does not engage in the guide channel. The damping element is so not guided in the guide channel movable, but is simple, designed for example as a block and is loose in the cavity. In general, the material of the damping element is not hard enough to form fine structures on it, which can be performed in the guide channel.

In a further preferred embodiment, a stationary with respect to the guide rail fixed stop is provided. The stop is located on the side facing away from the shock element of the damping element. The damping element is applied to this stop, so that the position of the damping element is defined within the guide rail by the stop. In a particularly preferred embodiment, a screw or bolt for attaching the stopper is provided, wherein the screw and / or the bolt pass through the stop and through the guide rail in the underlying door, in the frame or in the wall. The stop is thus not only connected to the guide rail but also directly to the underlying construction. As a result, very heavy door leaves can be damped by the arrangement according to the invention. In addition to the above-mentioned screw or bolt, a further screw connection is provided with which the stop can be fixed in the guide rail. For this purpose, for example, a grub screw that clamps the stop in the guide rail. This further screwing is particularly useful when the fitter first wants to pre-adjust the desired position of the stop within the guide rail and pierced only in a final step, the guide rail to insert the screw or bolt.

In an advantageous embodiment, the cap is connected or screwed directly to the stop. For example, the stop is in the cavity between the cap and guide rail. The above Screwing possibilities are then enforced by the cap and possibly by the stop and by the guide rail.

Furthermore, it is preferably provided that the damping element bears directly against the stop and / or the impact element rests directly on the damping element. Preferably, therefore, there is no further component between the damping element and the stop. The shock element should also come into direct contact with the damping element, so that the force is introduced directly into the damping element.

In an advantageous embodiment, it is provided that the impact element is divided into at least two sections, wherein the first portion faces the movement element and is guided in the guide channel, and wherein the second portion does not engage in the guide channel and engages in the cavity between the cap and guide rail. The two sections of the push element are in particular made integral with each other, so that the push element is in one piece. Over the first section, the push element is guided in the guide channels and thus linearly movable. The second section must be made slightly narrower so that it can engage in the cavity between the cap and guide rail and does not collide with the cap in the guide channel. Therefore, the second portion of the push member is not guided in the guide channel.

It is preferably provided that the impact element with respect to the cap or with respect to the damping element is only minimally movable. In a normal movement of the door so only the moving element but not the push element is moved with. In the end position then the movement element runs on the shock element. In particular, it is provided that at least one impact element stop is formed on the cap. This impact element stopper is in particular as one or more curved or threaded tabs formed. The impact element stop prevents the push element from completely moving out of the cavity between the cap and the guide rail. As a result, the guide rail is linearly movable relative to the cap to a limited extent. On one side, the impact element abuts against the impact element stop. On the other side, the shock element abuts against the damping element.

The guide rail preferably has a mounting surface. The mounting surface is the surface that comes into contact with the door leaf, the frame or the wall. In particular, mounting holes are provided in the mounting surface. These mounting holes fasten the guide rail. A guide rail height is defined perpendicular to the mounting surface. The cap can protrude slightly beyond the guide rail in the direction perpendicular to the mounting surface. In order to ensure a narrow structure of the arrangement in the direction perpendicular to the mounting surface, it is defined that the damping element is stretched so far that the cap in the direction perpendicular to the mounting surface by at most 20%, preferably at most 10%, of the guide rail height on the guide rail survives.

In an alternative embodiment it is provided that the cap in the direction perpendicular to the mounting surface by more than 20%, preferably more than 40%, the guide rail height projects beyond the guide rail. In this case, however, the moving element in the direction perpendicular to the mounting surface is very narrow and it is defined that the movement element in the direction perpendicular to the mounting surface by more than 20%, preferably at most 10%, the guide rail height projects beyond the guide rail. In this second alternative, an extension between the movement element and the cap is particularly preferably arranged. In particular, the movement element itself is extended or it becomes the impact element extended. Alternatively, the extension can also be used between the impact element and the movement element. It is crucial that the extension is so long that in the closed state of the door leaf, the output shaft of the door operator between the moving element and the cap is arranged. Thus, the cap with the damping element is moved so far outward in the direction of the axis of rotation of the door leaf, so that in the closed state, the lever which connects the output shaft of the door closer with the moving element, parallel to the guide rail space. Without this extension and too large a cap, the lever would abut the cap.

In a preferred embodiment, it is provided that the extension is positively and / or non-positively releasably connected to the movement element, and / or that the extension is positively and / or non-positively releasably connected to the push element. The extension can therefore be mounted on one side with the moving element and dismantled. On the other side, the extension can be assembled and disassembled with the push element. Alternatively, it is possible that the extension is integrally formed with the moving member and / or the push member.

Advantageously, the length of the extension is adjustable. This can be achieved for example by a multi-part extension, which is adjustable in length via perforated rails, slots or terminal strips. Alternatively, a mechanically shortenable (for example by sawing) part, preferably made of plastic, as an extension is possible.

The damping element comprises at least one elastomer block. The elastomer block is preferably in the form of a foamed elastomer block, in particular of cellular Vulkollan. Particularly preferred is the damping element only formed by these elastomer blocks. There is no need for wrapping or further processing of the elastomer blocks, since the elastomer blocks are securely received in the cavity between the cap and the guide rail.

The following is based on the FIGS. 1 to 5 the door actuator assembly 1 according to the first, not inventive embodiment described.

FIG. 1 shows the door operator assembly 1 integrated into a door frame 2 and a door leaf frame 3. In FIG. 2 the door frame 2 and the door leaf frame 3 are hidden. FIG. 3 shows an end view of Figure 2. In FIG. 4 is a guide rail 8 hidden. In FIG. 5 Furthermore, a cap 18 is hidden.

According to the FIGS. 1 to 5 the door actuator assembly 1 comprises a door operator 4, here designed as a door closer. The door operator 4 has an output shaft 5. One end of a lever 6 is rotatably connected to this output shaft 5. The door operator 4 is completely embedded in the door leaf frame 3. In FIG. 1 the upper, horizontal portion of the door frame 2 is not shown. In this portion of the door frame 2, the guide rail 8 is mounted. The guide rail 8 is designed here as a slide rail and extends in a longitudinal direction 16.

FIG. 2 shows in contrast to FIG. 1 the underside of the guide rail 8. The guide rail 8 is composed of a mounting surface 9 and two side walls 11. In the mounting surface 9 a plurality of mounting holes 10 are provided. About this mounting holes 10, the guide rail 8 is screwed to the door frame 2. The two side walls 11 are perpendicular to the mounting surface 9 and spaced from each other. In particular FIG. 3 shows, the two side walls 11 each have a shoulder 12. As a result, a guide channel 13 is formed between the mounting surface 9, the side wall 11 and the shoulder 12. The guide rail 8 has two guide channels 13. In these guide channels 13, elements in the guide rail 8 along the longitudinal direction 16 can be guided linearly movable. At the same time, it is ensured by the guide channels 13 that the guided elements can not be removed from the guide rail 8 in any direction perpendicular to the longitudinal direction 16.

In the guide rail 8, a moving element 7 is guided linearly movable. The moving member 7 is formed as a sliding member or slider. A movement direction 15 of the movement element 7 corresponds to the longitudinal direction 16 of the guide rail 8. In the movement element 7, an eye 14 is formed. The lever 6 is rotatable about this eye 14 connected to the moving element 7. Especially FIG. 4 shows that on both sides of the moving element 7 Gleitflügel 17 are formed. These sliding wings 17 engage in the guide channels 13.

Furthermore, a cap 18 is inserted in the guide rail 8. The cap 18 also has sliding wings 17 on both sides, which engage in the guide channels 13. Between the cap 18 and the guide rail 8, a cavity is formed.

At one end of the cap 18 is located between the cap 18 and the guide rail 8, a stop 19. The stopper 19 is attached via a first screw 20 and a second screw 21. The first screw 20 is designed as a grub screw. The second screw 21 is designed as a countersunk screw. By means of the first screw 20, the position of the stopper 19 is fixed in the guide rail 8. The second screw 21 passes through the guide rail 8, as for example FIG. 3 shows. As a result, the stop 19 can be connected via the second screw 21 fixed to the lying under the guide rail 8 construction.

In the cavity between the cap 18 and guide rail 8, a damping element 22 is inserted. This damping element 22 has here two elastomer blocks 23, which consist of foamed elastomer. Between the damping element 22 and the movement element 7, a push element 24 is arranged in the guide rail 8. The impact element 24 is formed in one piece, but has a first portion 25 and a second portion 26. On the first section 25, in turn, sliding vanes 17 are formed, which are guided in the guide channels 13. The second portion 26 has no sliding vanes 17 and thus can engage in the cavity under the cap 18. An area of the front of the second section 26 corresponds approximately to the surface of the end face of the damping element 22. These two end faces come to rest on each other, so that the movement of the movement element 7 is transmitted via the impact element 24 to the damping element 22.

FIG. 3 shows a guide rail height 28 and a projection 29. The two sizes are measured perpendicular to the mounting surface 9. In order to ensure a very narrow structure perpendicular to the mounting surface 9, it is defined that the projection 29 is at most 20% of the guide rail height 28. The damping element 22 is formed correspondingly long in the longitudinal direction 16, so that the corresponding force can also be damped.

The FIGS. 6 to 9 show a second embodiment of the Türbetätigeranordnung 1, which is according to the invention. The same or functionally identical components are provided in all embodiments with the same reference numerals. In FIG. 8 For the sake of clarity, the guide rail 8 is hidden. FIG. 9 only shows the cap 18.

In the second embodiment, in contrast to the first embodiment, the damping element 22 and correspondingly also the cap 18 does not extend so far in the longitudinal direction 16. However, to dampen a correspondingly large force here, the cap 18 and the damping element 22 in the direction perpendicular to the mounting surface 9 are designed to be larger. FIG. 7 here shows the guide rail height 28 and the projection 29. The projection 29 may be more than 20% of the guide rail height 28. Between the movement element 7 and the impact element 24, an extension 30 is formed. Preferably, this extension 30 also includes sliding wings for guiding in the guide channels 13. The projection of the movement element 7, the extension 30 and a majority of the push member 24 is defined as in the first embodiment and is at most 20% of the guide rail height. By the extension 30 ensures that in the closed state, the output shaft 5 of the door operator 4 between the cap 18 and the eye 14 finds room. It is thus avoided that the lever 6 abuts against the cap 18.

Also in the second embodiment it is provided that the impact element 24 has approximately the same end face as the damping element 22. Therefore, wedge-shaped stiffeners 32 are provided on the impact element 24, which stiffen an end wall 31 of the impact element 24.

Furthermore, in the second exemplary embodiment, the stop 19 has sliding wings 17 for guiding in the guide channels 13.

In particular FIG. 9 shows the cap 18 a shock stopper 34 formed as a tab. This shock element stopper 34 engages behind the wall 31 of the push element 24. As a result, the push element 24 is blocked in a direction of movement by the damping element 22 and abuts the push element stop 34 in the other direction of movement. In addition, shows FIG. 9 two holes 33 in the cap 18. About these two holes 33, the two screw 20, 21 are used, so that simultaneously with the attachment of the stopper 19 and the cap 18 is fixed relative to the stop 19. Further, the elastomer blocks 23 are fixed between the wings 17 from the stop 19 and the walls left / right of the wings 17 of the cap 18.

The FIGS. 10 to 14 show various embodiments and details of the Türbetätigeranordnung invention. These embodiments may be provided on both embodiments.

FIG. 10 shows a recess 35 in the cap 18. This recess 35 may be formed as a slot or as a continuous slot. When compressing the damping element 22 so the damping element 22 can extend through the recess 35.

FIG. 11 shows a closed cap 18. Here is a free space 36 between the damping element 22 and the inner wall of the cap 18 is provided so that an expansion of the damping element 22 is possible.

FIG. 12 shows an embodiment of the recess as further holes 37. Here, the damping element 22 can extend through the other holes 37 therethrough. The shock element stop 34, designed as a tab, is arranged laterally here.

FIG. 13 shows the use of two impact element stops 34, each of which laterally engage behind the impact element 24.

FIG. 14 shows that both the cap 18 and the damping element 22 in cross section can not be rectangular but also round.

Fig. 15 and 16 show a detail of the formation of the stopper 19 and the cap 18 for all embodiments. Fig. 15 shows the stopper 19 and the cap 18 in an exploded view. In Fig. 16 the composite state is shown.

The cap 18 has two parallel Kappenwandungen 38. In each cap wall 38, a wing 17 is formed by a notch. The notch is thus formed by the wing 17, which is in particular perpendicular to the cap wall 38, and two webs 40. The width of the webs 40 corresponds to the wall thickness of the cap 18, in particular the cap wall 38th

The stop 19 has two parallel end faces 41. The end faces 41 are perpendicular to the longitudinal direction 16. In the assembled state according to Fig. 16 stand the end faces 41 of the webs 40 opposite. As a result, the stop 19, regardless of the first and second screw 20, 21, fixed in the longitudinal direction 16 relative to the cap 18. The wings 17 of the stopper 19 lie on the wings 17 of the cap 18.

Preferably, therefore, a positive reception of the stopper 19 is provided in the cap 18, in particular to fix the stopper 19 in the direction of movement 16 relative to the cap 18.

The in the Fig. 15 and 16 shown positive engagement between the stopper 19 and cap 18 is particularly for the assembly of the door actuator assembly 1 of advantage. Before the stop 19 is connected by means of screws 20, 21 fixed to the door frame and / or the guide rail 8, the stop 19 is fixed by means of the notch relative to the cap 18.
