Description

Carrying and guiding device for holding portable, hanging door or wall elements

description

The invention relates to a carrying and guiding device for holding portable, suspended door or wall elements, which are held movably in stationary running rails, the running rails being fastened directly or via a hanging construction to a building ceiling.

Such a carrying and guiding device is known from DE 40 41 925 C1. In this carrying and guiding device, a running rail, in which the door or wall element is accommodated such that it can be moved via rollers, is fastened to a building ceiling via a substructure. So that the running rail can be attached to the substructure, the running rail and the substructure must be drilled on site. The resulting drilling chips can get into the running rail and remain there. This can lead to a deterioration in the rolling behavior and often also to damage or failure of the rollers and consequently to complaints.

It is therefore an object of the present invention to provide a carrying and guiding device of the type mentioned in the preamble of claim 1, in which assembly-related impairments can be excluded.

This object is achieved by the features specified in claim 1. Advantageous further developments result from the subclaims. The solution according to the invention has the advantage that an intermediate profile (screw channels) can either be provided on site or already during production with all the necessary bores or be subjected to other processing steps and can then be attached to the ceiling of the building with the hanging construction before the running rail is attached the intermediate profile is attached. This eliminates the risk of drilling or other swarf getting into the running rail and causing impairments. Even if the running rail were still to be provided with holes for attachment to the intermediate profile, this would not be further disadvantageous since these drilling chips could fall downward out of the running rail which is open at the bottom. But even this is avoided, since the track is already provided with a row of holes during its manufacture.

A high degree of functionality can thus be guaranteed with the carrying and guiding device according to the invention.

According to an advantageous development, the intermediate profile is designed as a double-T beam, which is connected to the closed side, for. B. a hollow box-shaped track is connected. A double-T beam ensures good dimensional stability due to its high moment of inertia. By attaching the running rail to its lower flange, this dimensional stability is used in a particularly favorable manner.

According to a preferred development, the double T-beam has a lower screw channel, which is used to connect the running rail and which is arranged essentially centrally in the lower flange, so that the running rail can be easily attached to the double-T beam in the longitudinal direction of the double-T beam runs. This makes the fastening of the running track particularly easy.

In order to create additional mounting options on the double T-beam, e.g. B. for fastening a suspended ceiling, it is provided according to the invention that the lower flange is provided on at least one end face with a lateral screw channel extending in the longitudinal direction of the double-T beam.

This configuration can advantageously be supplemented by the measure according to which the lower flange is provided on both end faces with a longitudinal screw channel running in the longitudinal direction, since fastening options are thus created on both sides of the double-T beam.

According to an advantageous further development, a holding device which is preferably designed as an angle can be inserted, in particular screwed, into the lateral screw channel. Such an angle can e.g. B. serve as a support for a plasterboard, which can form the suspended ceiling.

In order to save weight, the web of the double-T beam can be provided with a central channel according to a preferred embodiment. However, this central channel can also be used to hold objects such as lines and the like. In addition, an additional stiffening element could also be arranged or inserted in this central channel.

According to an advantageous development, the upper flange has an upper screw channel, which is arranged essentially centrally in the upper flange and runs in the longitudinal direction of the double-T beam. This

Screw channel improves the attachment options on the intermediate profile continues, so that z. B. the hanging structure can be attached easily, quickly and safely.

For reasons of symmetry, it is preferably provided that the lower screw channel and the upper screw channel are aligned with one another and can be arranged in the center region of the double-T beam.

According to a preferred development, at least one centering groove running parallel to the upper screw channel is provided in the upper flange. This centering groove considerably simplifies and improves the machining of the double-T beam, since fixed reference lines are already specified.

The processing can be further simplified and improved if, according to an advantageous development, two centering grooves are provided which run parallel to one another and are preferably arranged at the same distance from both sides of the upper screw channel.

So that a fixed reference line is also available with regard to the web of the double-T beam, the web has at least one further centering groove.

According to an advantageous embodiment, U-shaped cutouts are provided in the upper flange on at least one side, the longitudinal extent of which is oriented perpendicular to the longitudinal direction of the double-T beam. These millings make it particularly easy to connect the intermediate profile to the hanging structure, since the hanging structure can easily be hooked into these millings.

In order to enable a grid-like suspension on the hanging structure, the invention provides that the U-shaped cutouts are evenly distributed over the length of the double-T beam.

If, according to an advantageous further development, U-shaped cutouts are provided on both sides of the upper flange and the U-shaped cutouts on one side of the flange are offset from those on the other side of the flange, a secure mounting of the intermediate profile can be ensured ,

So that all fastenings can be carried out easily, quickly and without much effort, according to an advantageous further development it is provided that the screw channels have finished thread grooves, into which threaded screws can be screwed without machining. Thus, screws can be screwed directly into the screw channels on site without further processing such. B. tapping, required.

According to an advantageous development, the hanging structure consists of threaded rods and / or lateral supports. Threaded rods are readily available as stock goods, they can be easily and easily shortened to any length and are particularly suitable for easy hanging in the U-shaped cutouts. Side supports increase the stability of the entire construction and help to suppress vibrations.

When assembled, the threaded rods engage in the U-shaped cutouts and thus allow the intermediate profile to be easily attached to the building ceiling.

So that the threaded rods cannot accidentally slip out of the cutouts, the threaded rods are advantageous Continuing education with a locking plate on the double-T beam each secured its position.

According to an alternative, the locking plate can be screwed into the middle screw channel of the upper flange. This is particularly advantageous if a non-positive connection between the intermediate profile and the threaded rod is desired.

According to an alternative embodiment, the locking plate can also have an angle with which it engages in the upper screw channel. This is particularly advantageous if a positive connection between the intermediate profile and the threaded rod is desired.

The locking plate can also be used in an advantageous manner to support the lateral support. For this purpose, it is provided according to the invention that the locking plate is provided on the side opposite the threaded rod with a tab which supports the lateral support in an articulated manner. This means that the lateral support can be aligned at any angle to the intermediate profile.

So that an exact adaptation and alignment to the local conditions can be made possible, the suspension and lateral support are adjustable in length, in particular telescopic.

Advantageously, the lateral support consists of at least two telescoping tubular or square profiles. These standardized profiles are easy to obtain and can be easily adapted to any length.

The shape of the running rail is arbitrary. The intermediate profile can be adapted to the geometry of the running rail. Further features and advantages of the invention result from the following description of a preferred exemplary embodiment.

Show it:

Figure 2: another perspective view of the invention

Carrying and guiding device,

Figure 3 is a view of the support and guide device according to the invention from above and

Figure 4: a front view of the carrying and guiding device according to the invention.

In Figures 1 to 4, the carrying and guiding device according to the invention is shown and explained in a preferred embodiment.

For a better overview, the sliding door or wall elements on the carrying and guiding device are not shown.

The carrying and guiding device according to the invention has e.g. B. a substantially designed as a U-shaped box section rail 1, the opening of which points downwards. In the running rail 1, guide rollers or the like (not shown) are slidably mounted in the longitudinal direction of the running rail 1, on which one or more door or wall elements (also not shown) are held via idler rollers.

The running rail 1 can be made of a suitable material, such as aluminum,

Light metal or the like, e.g. B. as an extruded part. In the manufacture of the track 1 z. B. all necessary Ribs, webs, grooves, etc. can be formed directly. In addition, a row of holes can be provided in the surface opposite the open side, which is used to fasten the running rail 1 to the hanging device which will be explained in detail later. This row of holes preferably runs centrally and in the longitudinal direction of the running rail 1.

The running rail 1 is fastened to an intermediate profile 2. The intermediate profile 2 is designed as a double-T beam, which can also be designed as an extruded profile. The double-T beam has an upper flange 3, a central web 4 and a lower flange 5. The lower flange 5 lies essentially over the entire surface of the surface of the running rail 1 opposite the open side. For attachment to the running rail 1, a lower screw channel 6 is provided in the intermediate profile 2, which is arranged in the region of the web 4 and runs centrally in the longitudinal direction of the double-T beam. This screw channel 6 is provided with grooves on its side surfaces, so that a fastening screw 7, for. B. a hexagon screw, can be screwed directly and without further preparatory work into the screw channel 6. Thus, the running rail 1 can be screwed on quickly and easily in the lower screw channel 6 using the fastening screws 7. Thanks to the fastening option, the track 1 can also be changed quickly without the substructure having to be changed.

The web 4 of the double-T beam is preferably provided with a rectangular central channel 8 which runs in the longitudinal direction of the intermediate profile 2. This middle channel 8 can be provided on the one hand for reasons of weight saving, but on the other hand it can also be used to hold cables, lines or the like. In addition, it can also be used to accommodate an additional (not shown) stiffening element, which, for. B. in the central channel 8th can be inserted for z. B. very heavy sliding wall elements.

A lateral screw channel 9 is provided on each end face of the lower flange 5 and, like the lower screw channel 6, is provided with grooves on its side faces and extends in the longitudinal direction of the double-T beam. Any different holding or supporting elements can be fastened in these lateral screw channels 9. As shown in Figure 4, z. For example, an L-shaped bracket 11 can be screwed on by means of corresponding screws 10 as a support for a plasterboard (not shown) which serves as a suspended ceiling. On the other hand, it would also be possible, without the angle 11, to insert the plasterboard directly into the lateral screw channel 9. In such a case, the thread in the lateral screw channel 9 would have no function.

The upper flange 3 of the double-T beam is also provided with a screw channel 12. This upper screw channel 12 runs parallel to the lower screw channel 6 in the region of the web 4 in the longitudinal direction of the intermediate profile 2. The upper flange 3 is further provided with U-shaped cutouts 13 which are introduced into the upper flange 3 from the side and their longitudinal extent is aligned perpendicular to the longitudinal extension of the intermediate profile 2. The U-shaped cutouts 13 are arranged at equal intervals along the two longitudinal edges of the upper flange 3 such that the cutouts 13 on one side are offset from those on the other side. In principle, however, it is also possible for the cutouts 13 to lie directly opposite one another.

The millings 13 are used for receiving z. B. of threaded rods 14, with which the intermediate profile 2 and thus the running rail 1 can be suspended from a (not shown) building ceiling. This will a threaded rod 14, as indicated by the arrows in Figure 2, inserted from the side into one of the U-shaped cutouts 13 in the upper flange 3. One or more nuts 15 screwed onto the end of the threaded rod 14 serve as supports or for fastening the threaded rod 14 to the intermediate profile 2. A locking plate 16 is provided so that the threaded rod 14 cannot laterally slip out of the cutout 13. This locking plate 16 is provided with a bore for the passage of the threaded rod 14. At the end of the locking plate 16 facing away from the bore, in accordance with one embodiment, a bevel 17 is provided, so that the locking plate 16 describes an L-shaped shape in the side view, the shorter leg forming the bevel 17. With this bevel 17, the locking plate 16 can engage in the upper screw channel 12 (see FIG. 1), so that the threaded rod 14 is held securely in the cutout 13.

According to another embodiment, also shown in FIG. 1, the locking plate 16 can also be provided with a screw hole 18 (see FIG. 2), so that the locking plate 16 can be secured in position in the upper screw channel 12 by means of a retaining screw 19.

So that the intermediate profile 2 or the running rail 1 can be securely stored not only in the vertical direction (via the threaded rods 14) but also in the lateral direction, the locking plate 16 can be extended beyond the screw hole 18 and at this extended end with a tab 20 be provided. On. a lateral support 21 of this tab 20 is pivotally mounted. In the exemplary embodiment shown, the lateral support 21 consists of two telescopic square profiles 22, but it can also consist of corresponding tubes or the like. Instead of a telescopic design other configurations are also possible as long as they allow a variable change in length.

The two square profiles 22, which are guided one inside the other, can be fixed in their respective positions relative to one another by means of clamping screws 23. Furthermore, the square profiles 22 are fastened to the building ceiling (not shown) via any construction. This construction can e.g. B. consist of two hinged to the square profiles 22 brackets 24 which are screwed to the housing ceiling via fastening screws 25.

Since the threaded rods 14 and the lateral support 21 can be adapted in length to the on-site conditions, it is ensured that a secure attachment of the carrying and guiding device according to the invention can be guaranteed under all conditions.

One or more centering grooves 26 are provided on the top of the upper flange 3 and on the side surfaces of the web 4. In the exemplary embodiment according to FIGS. 1 and 2, two centering grooves 26 are provided in the upper flange 3, which run parallel to one another and parallel and at the same distance from the upper screw channel 12 to the right and left of the latter. On the web 4, two center grooves 26 are also provided on each side, which are arranged parallel to one another. , . * -
