Sliding door element and suspension in front of a wall

for that

The invention relates to a sliding door element, comprising a door leaf which is guided in front of a wall of a building and is suspended from a guide element which is attached to the wall and runs approximately horizontally.

Such a sliding door element can be found, for example, in DE-OS 195 4 6 98 6. A roller device is attached to the sliding door element, the elements of which, such as rollers, guide rails and the like, are covered with a cover box, here: cladding profile. The cladding profile merges into a vertically arranged stop post. The cover box and the stop post are complex to manufacture and assemble on site.

The object of the invention is to design a novel, cost-effective sliding door element and its suspension which is space-saving and easy to install.

This object is achieved by a sliding door element of the type mentioned above, which is characterized in that - a groove is incorporated in the material of the door leaf/into which a guide rail is embedded,

and the guide element attached to the wall - when assembled - forms a sliding or roller guide with the guide rail.

The guide element running along the wall can be a plastic or metal profile, preferably a T-profile with unequal T-bars, whereby the sliding door element is pushed onto the smaller T-bar via the guide rail. The T-profile with the guide rail embedded in the door leaf forms a sliding or sliding guide. It is not impossible to use other profiles instead of the T-profile, for example U-, C- or L-profiles, provided that they are compatible with the guide rail and ensure low-friction guidance.

With a roller guide, the guide element can consist of a bar and several rollers mounted on it. It is also conceivable and technically feasible to do without the bar if the rollers are mounted directly on the wall construction.

The guide rail embedded in the groove is preferably designed as a C-profile with angled, mutually facing C-legs, which ensure a stable mount on the rollers or the T-profile.

Both the rollers and the T-profile of the guide element and the guide rail can be made of plastic or metal. However, the aim is to have a "uniform" design of the fitting, in which the guide rail, rollers and the guide element are made of aluminum or stainless steel, for example.

To reduce rolling noise, the metal rollers that come into contact with the metal guide rail can be plastic-coated, as is well known. The plastic coating generally applies to metal elements of the suspension that come into contact with corresponding metal "counter-elements".

The sliding door element according to the invention consists only of a door leaf and a guide rail that is installed in the groove at the factory. This has proven to be particularly advantageous for low-cost prefabrication, as a "completely normal" standard door leaf can be used. In addition, storage and transport costs can be reduced compared to those of conventional sliding door elements with a cover box.

The sliding door element with suspension according to the invention is primarily intended for external and internal walls or partition walls of buildings. However, it is expressly pointed out that the concept can also be used for furnishings such as wardrobes.

Further features and advantages of the invention can be seen from the following embodiment, which is explained in more detail with reference to the drawing. The figures of the drawing show in detail:

Fig.4 Section BB according to Fig.3

Fig. 1 shows a schematic of a sliding door element 1 which is movably suspended on a guide element attached to a wall 5. No door frame or stop post is mounted on a wall opening marked "6"; these are superfluous in the present case. The guide element 2 is aligned horizontally and screwed to the wall (screws 7; Fig. 2a). The guide element 2 is composed of a flat strip 22 and several rollers 11.1...11.2 each mounted on this via a bolt 8.

The sliding door element 1 consists of a conventional, flush-fitting door leaf 30 made of wood material and a guide rail 3 which is set into and secured in a rectangular groove 4 milled into the door leaf. The groove 4 is at a predetermined distance A from the upper edge 9 of the door leaf. The guide rail is designed as a C-profile 13 with angled, mutually facing C-legs 13.1, 13.2. The strip 22 equipped with the rollers 11.1...11.2 and the guide rail 3 form a roller guide 20.

The door weight is evenly supported by the large number of plastic-coated rollers 11.1...11.&eegr;. The roller guide described ensures particularly smooth running and an extremely long service life, as there is practically no wear on the individual rollers.

The overall visual appearance of the sliding door element is aesthetically very high quality.

Furthermore, Fig. 1 shows two door stops 14.1, 14.2 arranged on the guide element 2, which are shown in detail in Figures 3 and 4. The two door stops 14.1, 14.2 each consist of a threaded bolt 16 and a rubber ring 17 attached to it. At both ends of the guide element 2 there are three threaded holes 21.1, 21.2, 21.3 for receiving the threaded bolt 16. This allows the position of the door stop 14.1, 14.2 to be adapted to the width of the door leaf 30 or the wall opening 6.

Both the guide element 2 with rollers 11.1...11.&eegr; and door stops 14.1, 14.2, as well as the C-profile 13 placed in the groove are made of stainless steel. To minimize noise, the rollers 11.1...11.&eegr; at „15* (contact surface) are coated with plastic.

Furthermore, the door leaf 30 has a lower groove 18 for receiving a floor guide element 19, as is known per se.

The fitting, i.e. the guide element 2 with the rollers 11.1...11.&eegr; forms a compact module that only needs to be mounted on the wall by aligning it and screwing it on. After the guide element 2 has been attached, the following steps are carried out: the door leaf 30 is pushed on, the two door stops 14.1, 14.2 are screwed into the corresponding threaded holes and the floor guide is mounted.

Fig. 2b shows another embodiment in which the guide element 2 is designed as a T-profile 12 with unequal T-legs, which forms a sliding guide 10 with the guide rail 3 already described. The T-profile 12 and the C-profile 13 of the guide rail 3 are made of aluminum, with the interior of the C-profile 13 being plastic-coated.
