DE10120002C1 - Running track arrangement connected to a fixed part of a sliding door - Google Patents

Abstract

The invention relates to a running rail arrangement which is arranged on a fixed part of a sliding door, the sliding door being guided on the running rail arrangement by means of roller carriages. The invention is directed to the fact that the running rail arrangement consists of two, mutually parallel, spaced-apart running rails, between which a support roller of the roller carriage is essentially positively guided without play.

Description

The invention relates to a fixed part of a sliding door or Substructure connected track arrangement with a Slides guided on the running rail arrangement by means of roller carriages wing.

From the brochure "order and Design Manual, DORMA Manet, the glass-shaping system" imprint 6/98, page 3/08, a sliding door with two side parts is known in which the sliding door is guided by means of two carriages suspended on a guide rail. Such sliding doors must in particular be secured against unintentional or inadmissible lifting or lifting of the guide rollers from or out of the guide rail; For this purpose, below the guide rail arranged locking elements are used, as shown on page 3/02 of the aforementioned brochure. Such locking elements are on the one hand susceptible to wear; on the other hand, they are easily removable, which is undesirable for safety reasons. From the illustration on page 3/08 it can also be seen that the sliding door shown there can swing about its roller support transversely to the direction of displacement in the absence of a floor guide, which is also undesirable.

In addition, a C-shaped profile is known from GB 576.952 the upper and lower legs of the rollers of a sliding vane gels are positively guided. Such a profile has a relatively high weight and is also expensive to manufacture dig dig.

The object of the invention is to avoid the aforementioned disadvantages a track arrangement of the type mentioned to improve that with defined roller guidance a levering out or levering the idler roller out of or from the running rail is prevented. Furthermore, the track arrangement in interaction with the Arrangement of the support roller relative to the running rail has a stabilizing effect be exercised on the sliding sash, such that when exclusively hanging sliding sashes - without a floor guide - horizontal swinging movements of the sliding sash around the idlers support orthogonal to the direction of displacement can be minimized.

The invention solves this problem with the teaching of claim 1.

The forced distance of two parallel runs rails with an essentially play-free positive guidance of the support role of the roller carriage between these rails prevents verver casually levering or levering the idlers, doing this compulsively leadership cannot be overridden by simple means, which Security aspect improved. Because such rails made of round bars exist and the idler a circular cross section of the The round bars have adapted roller shells, the additional results Effect that the idler roller guide a swinging of the sliding sash across counteracts the running direction. The rails do not have to inevitably consist of round bars; all that matters is that with the roller jacket adapted to the cross section of the running rail Carrier roller a transverse feed direction of the sliding wing effective constraint guidance of the idler roller on both superimposed tracks he follows.  

The running rails are used to achieve a defined guidance of the support roller tabs in the area of the fixed part or the substructure by means of the fixed part or the substructure distant. The aforementioned tabs have exactly spaced through aisle holes for receiving screw-in into the running rail mounting screws so that the distance is parallel to each other other running rails are precisely defined by the tabs, which in turn leads to a defined guidance of the supporting roller between the Guides rails.

Design features of the invention are the subject of the Unteran claims.

The invention is preferably used for a track arrangement dung, with a sliding glass door between two side glass walls is arranged; here the running rails are connected to the Lichen glass walls in such a way that arranged in the side glass walls Border conical clamping elements, their spacing corresponds to the distance between the running rails. Such a conical clamp elements are in principle - but for attaching a roller dare carrying tab - from page 3/02 of the aforementioned Pro known.

In a further embodiment of the invention, the conical clamp elements a through hole for the passage of the tab comprehensive fastening that can be screwed into the running track screw on, the through hole in the clamping element as long hole can be formed. Because the holes in glass walls are certain Subject to tolerances, it has proven practical in practice sen, at least one of the stacked, the tab and the Clamping elements defining the slide rails with an elongated hole  hen to de at a predetermined by the holes in the tab defined distance of the running tracks an adaptation to the hole tolerance zen of the glass wall without tension in the Glass wall can be initiated.

The above-mentioned, the tab embracing and into the track screwable fastening screw can in a further embodiment of the Er be integral part of the conical clamping element.

The roller carriage connected to the movable glass sliding door has a bearing block receiving a roller bearing and a support roller (Bearing shaft), on the end face facing away from the support roller Clamping element for the frictional clamping of the sliding sash is arranged. To attach the clamping element to the bearing block a clamping screw or fastening screw is provided that the Clamping element encircled, in the bearing block and with the bearing is screwed. Again, to adapt to possible Boh tolerances of the sliding glass door with respect to the be in the running direction neighboring roller carriages by the clamping screw or fastening screw-enclosed hole in the clamping element or Opening formed as a circular hole or as an elongated hole his.

The invention is described below using an exemplary embodiment alternative embodiment of the clamping element explained in more detail.

The sliding sash 1 as well as fixed parts 2 according to FIG. 1 can basically be made of any material; in the exemplary embodiment they are shown as side glass walls 10 with a glass sliding door 11 . The apparent from FIGS. 1, 2 and 3, track assembly 3 be standing from an upper running rail 5 and a lower guide rail 5 ', between which the conveyor roller is forcibly guided. 6

As can be seen in FIGS. 1 and 3, a tab 7 is provided which has precisely defined through bores 8 and which bears against the side glass walls 10 . The defined bores 8 of the tab 7 define the mutual distance between the running rails 5 and 5 '. The through bores 8 of the tab 7 are covered by Ben 9 fastening screws, which in turn engage in clamping elements 13 and 13 'which engage in bores 12 of the glass walls 10 . To compensate for hole tolerances in the glass walls 10 , the lower clamping element 13 'in the image plane un' has an elongated hole 16 , so that a tension-free connection to the glass walls 10 is possible despite the defined spacing of the running rails 5 and 5 '.

The roller carriage 4 is also connected to the glass sliding door 11 by means of a clamping element, which - depending on the tolerance of the holes in the glass sliding door 11 - as a clamping element 13 (with a circular hole), as a clamping element 13 '(with an elongated hole) or can be designed as a clamping element 14 (with an integral fastening screw 17 ). The roller carriage 4 shown in FIG. 10 has a La gerwelle or bearing block 19, on which the actual supporting roller 6 from facing end face 20 of the clamping member 13, 13 'or 14 is arranged. The aforementioned clamping element is screwed by means of a fastening screw 21 or a fastening screw 17 (see FIG. 8) to the bearing block 19 , which at the same time carries a roller bearing 18 for the supporting roller 6 .

From Fig. 4 and from Fig. 5, the arrangement of the through hole 15 formed as an elongated hole 16 'can be seen by means of which an equalization of hole tolerances in the glass wall or in the glass sliding door is possible.

Fig. 6 shows a side view of an embodiment of a cover 22 which the outer end of the clamping elements 13 or 13 'bil det. To lock the cover 22 in the cover receptacle 23 of the clamping element 13 or 13 ', an elastic insert 25 inserted into a groove 24 of the cover 22 can be provided.
