Description

The invention relates to a cover for a slide rail, wherein the cover is secured against lateral displacement in the longitudinal direction of a slide rail. The slide rail is useful in connection with a door closer or the like for opening and / or closing a door.

In the DE 10 2004 012 638 discloses a slide, which is covered by a U-shaped cover. This cover is open at its end faces and has inwardly projecting locking lugs, which correspond with locking recesses in the guide rail. If the slide rail is in operation, then loads on the slide rail, which are transmitted to the cover. This creates the disadvantage that the cover moves laterally from its proper position laterally in the longitudinal direction of the slide rail. This depends on the frequency of use of this slide rail. The more frequently the slide performs its function, the sooner the cover element shifts. To bring the cover back to its proper position, it is necessary to push it by hand to the proper position. This push back is carried out not only by people who mount such slides, but for the most part from the user circles. Furthermore, the cover is locked in such a way that it can be removed by hand. As a result, manipulation of the slide by unauthorized persons are possible.

It is therefore an object of the present invention to provide a cover for a slide rail of the type described above, which is simply designed, includes a displacement protection and works reliably and is inexpensive to manufacture. It is a further object of the present invention to provide a cover which is to disassemble on a cost-effective basis only with tools.

To solve this problem, a cover with the features of claim 1 is proposed. In the dependent claims preferred developments are carried out.

For this purpose, the invention provides that the cover shows at least one precaution, which is based to limit the displacement movement of the cover positively against the corresponding provision of the guide rail and / or the mounting adapter. The provisions are corresponding surfaces and / or edges or the like which are present on the cover element and / or the guide rail and / or the mounting adapters. Furthermore, the cover member is U-shaped, wherein in the manufacture of a bias voltage is attached to the cover.

This has the advantage of stopping the lateral movement of the cover, which is pronounced in the longitudinal direction of the slide, so that the cover is held at the proper position during operation of the slide and to achieve a spring function of the two open legs of the cover.

Another advantage is that a displacement of the cover by surfaces of the cover and surfaces of the guide rail is prevented.

The required surfaces on the cover are inexpensively mounted directly in the production of the cover. The usable surfaces of the guide rail, however, are available without additional effort, since the end faces of the guide rail are used, which arise when the guide rail is made to the required length.

Another advantage is that at least a portion of the cover with at least a portion of the guide rail forms a gap.

This gap can be used for a tool to disassemble the cover from the guide rail can. This has the further advantage that during the disassembly of the cover, the surface of the cover is not damaged in the field of view.

Another improvement is that the cover is U-shaped and thus receives a bias in the manufacture and thus holds the locking connection, the cover member so on the guide rail and the mounting adapters that the cover is to be removed only with tools. As a result, an unauthorized action on the slide is difficult.

The invention is described by way of example with reference to the following drawings.

FIG. 6 shows the detail X from the FIG. 5 , Here, a gap A between the cover 1 and the guide rail 2 can be seen, which is located within the detail Y.

FIG. 7 shows the detail Y from the FIG. 6 , The gap A between the cover 1 and the guide rail 2 is formed by the surfaces 8 and 9. Furthermore, the surface 6 of the cover 1 and the surface 7 of the guide rail 2 are shown.

In the illustrations, only the parts relevant to the invention are shown. All other functional elements are not shown for clarity.

The slide rail, which is used in conjunction with a door closer or door opener for opening and / or closing a door or the like, is mounted by two mounting adapters 3, 4 by means of elongated holes 10 to a door, a door frame, a wall or the like. The mounting adapters 3 and 4 are inserted into the respective ends of the guide rail 2 to the contact surface 4a, which leans against the guide rail, and each secured with a screw 5. The cover member 1 is pushed onto the guide rail 2 and locked so that the cover 1, the guide rail 2 and the two mounting adapters 3, 4 partially covers. The guide rail 2 is not covered at least in the portion of the cover 1, in which the slider, not shown here, must be freely accessible for its function. The cover 1 is U-shaped and open at its respective end. The locking of the cover 1 via a positive locking connection to the guide rail 2 and the mounting adapters 3 and 4. The surface 1 d of the cover 1 and the surface 2b of the guide rail 2 form in this section a plane which results in that no protruding Edge is present.

As the FIG. 3 shows, the cover member 1 in the assembled state with the guide rail 2 and the mounting adapters 3 and 4 is connected.

By loading, which rests on the sliding rail in the use of the door and is transferred to the cover 1, the respective corresponding surfaces 6 and 7 or 6a and 7a lean against each other, wherein the position of the cover 1 by the leaning of this Surfaces is held. When loading the slide rail and thus on the cover 1, the cover 1 is only moved so far until one of the surfaces 6 or 6a is based on their corresponding surface 7 or 7a. In order to achieve a slight displacement of the cover 1 when leaning against these surfaces, the distance between the surfaces 6 and 7 and 6a and 7a is kept as low as possible, taking into account manufacturing tolerances. By leaning on the corresponding surfaces 6 and 7 or 6a and 7a further displacement of the cover 1 is prevented in the direction of displacement. The direction of displacement is the direction of the longitudinal axis of the slide rail.

The cover member 1 is formed during manufacture so with bias that it retains a tight fit on the guide rail 2 and the mounting adapters 3 and 4 after assembly. This fixed seat is chosen such that the cover 1 is not to be removed by hand and thus a tool is required. The cover 1 further comprises a surface 8 which forms a gap A with a further surface 9 of the guide rail 2. In order not to damage the surface of the cover 1 during disassembly of the cover 1 with a tool, the gap A is designed such that a tool is inserted into the gap A, so that the cover 1 can be levered and disassembled from the guide rail 2.

If the inside width of the surfaces 6 and 6a of the cover element 1 is compared with the spacing of the surfaces 7 and 7a of the guide rail 2, the dimension between the surfaces 6 and 6a of the cover element 1 is greater than the distance dimension of the surfaces 7 and 7a of the guide rail 2 This ensures that the cover element 1 can be positively pushed and latched onto the guide rail 2 and the mounting adapters 3 and 4 and the corresponding surfaces 6 and 7 and 6a and 7a each have a distance from each other. The distance The surfaces 6 and 7 and 6a and 7a should be chosen as small as possible, taking into account the manufacturing tolerances. This distance decreases in the displacement of the cover 1 in the longitudinal direction of the slide until the surfaces 6 and 7 or 6a and 7a lean against each other. By leaning the surfaces 6 and 7 or 6a and 7a further displacement of the cover 1 in the longitudinal direction of the slide rail is prevented.

Therefore, it is important that the distance of the respective corresponding surfaces is made as small as possible so that the displacement occurring is as small as possible by having to pass through the corresponding surfaces as little as possible before they lean against each other and thus one prevent further displacement of the cover 1.

The cover 1 can be made of a plastic material and of an extruded profile. Furthermore, there is the possibility that the cover 1 is made from a stamped and bent part.

The areas of the surfaces 6, 6a, 7, 7a, 8 and 9 indicated in this invention are shown by way of example. It is understood that the specified surfaces can also be arranged on other areas of the cover 1, the guide rail 2 and the mounting adapters 3, 4, to prevent displacement of the cover 1 and continue to ensure disassembly of the cover 1 of the guide rail 2 ,

Furthermore, a plurality of corresponding surfaces may be present both on the cover element 1 and on the guide rail 2 and on the mounting adapters 3, 4. The surfaces indicated in this exemplary embodiment and their corresponding surfaces can furthermore be selected as stop elements of the most varied types, wherein, for example, pins can be used as stops for the displacement corrections. Here, too, the stop elements are used in such a way that the distance between the stop elements themselves and / or corresponding stop elements, taking into account tolerances, is chosen as small as possible. These stop elements can also be present on the cover element 1 as well as on the guide rail 2 and on the mounting adapters 3, 4.

Furthermore, it is also possible to use only edges of the cover 1 and the guide rail 2 to realize a lateral boundary of the displacement of the cover 1 and a gap for a tool for disassembly of the cover 1 of the guide rail.

The present invention is further applicable to covers for door closers, door openers as well as automatic actuators for doors or the like.
