Description

The invention relates to a sliding sash of a sliding door arrangement, in which support rollers for the sliding sash are stationary. The sliding leaf has a surface element in which an edge profile is placed on at least one end face facing the support rollers. The invention further relates to a sliding door assembly with a bottom profile with fixed support rollers and at least one sliding sash.

Opposite sliding door assemblies, in which the sliding leaf has a supporting frame, are arranged in the rollers, the aforementioned sliding door assembly allows for a given size of a building opening, the use of a larger area element, such as a larger insulating glass pane. In addition, a visually elegant appearance of the sliding sash is made possible, since this has only a very narrow edge profile compared to a supporting frame. The support rollers are preferably mounted in a floor profile, which is sunk in a floor of a building and thus mounted flush with the floor.

Such a sliding door arrangement is for example from the document WO 2010/024703 A1 known. In this arrangement, a U-shaped edge profile is placed on an insulating glass as a surface element, wherein the edge profile has on its side facing away from the surface element raceways, with which it rests on the support rollers.

In self-supporting frame, the surface elements are usually supported only at a few selected points by so-called glass blocks in the frame. However, in the case of the present sliding sashes, the edge profiles are not alone capable of distributing the weight forces of the surface element which are selectively acting on the support rollers laterally along the end face of the surface element. Instead, the surface element itself is used for receiving and distributing the punctual forces. For this purpose, the surface element is located directly on edge profile and is optionally glued to this.

For large insulating glass panes and in particular for large triple insulating glass panes, it is only possible with great effort, if at all, to provide a side edge in which the cut edges of all the glass panes of the insulating glass pane lie as far as possible in one plane. A section by section However, over the entire length of the front side projecting glass leads to an uneven distribution of forces on the glass, which can lead to chipping or glass breakage. A height compensation of the individual discs by an introduced adhesive layer is possible only with smaller height deviations. The reason for this is that the uniformity of a thicker layer of adhesive between the insulating glass pane and the edge profile is difficult to control, so that a consistent and uniform support over the entire length of the face of the surface element is hardly guaranteed.

It is therefore an object of the present invention to provide a sliding leaf and a sliding door arrangement of the type mentioned, in which also large surface elements, in particular triple insulating glass panes, can be used in a sliding door arrangement with fixed support rollers. In particular, a uniform force transmission between the edge profile and the surface element is to be achieved with good tolerance compensation.

This object is achieved by a sliding leaf of a sliding door assembly and a sliding door assembly having the features of the respective independent claim. Advantageous embodiments and further developments are the subject of the dependent claims.

An inventive sliding leaf of the type mentioned above is characterized in that between the end face of the surface element and the edge profile extending in the longitudinal direction of the edge profile support strip is inserted from plastic.

The edge profile is preferably a metal profile or a plastic profile of a hard plastic such as PVC (polyvinyl chloride), possibly with glass fiber reinforcement. In contrast, the support bar is softer and preferably has a Shor A hardness of 60 to 80. It can be easily pressed in and thus produce a thickness compensation. At the same time, it has a uniform thickness, which leads to a good and uniform fit of the edge profile on the surface element.

In a preferred embodiment of the sliding leaf, the support strip extends in one or more parts substantially over the entire length of the end face of the surface element. Preferably, the support supports the front page of the surface element thereby also over its entire width. Thus, the weight of the entire surface element can be transmitted as evenly as possible to the edge profile.

In a further preferred embodiment of the sliding leaf, however, the support does not support the end face of the surface element over the entire surface but rather in a plurality of support points distributed as uniformly as possible. Due to the not full-surface design of the pressure on the support at the support points is increased. Even when using a relatively hard plastic for the support this leads to a sufficient deformability at the support points, so that a thickness compensation is guaranteed to compensate for unevenness of the surface element on the front page.

For this purpose, the support may comprise, for example, at least one web extending in the form of a wave, wherein the web may, for example, have a rectangular cross-section. Alternatively, the support may be ladder-shaped with at least one longitudinal web extending in the longitudinal direction and a plurality of transverse webs. Through the structures mentioned remain free spaces in which the surface element is not supported. In these free spaces, an adhesive or a sealing compound can be introduced, by which or a secure connection of the surface element is ensured with the edge profile.

In a further preferred embodiment of the sliding leaf, the support can be varied by swaging or pulling it in the longitudinal direction in its width. This may, for example, be well implemented on an overlay comprising a rippled web. The support can be adapted in its width to different thickness surface elements and does not need to be made separately and kept in all required widths. In contrast to the width, the length can be adjusted easily.

In a further preferred embodiment of the sliding leaf, the support has a structured surface on its upper and / or lower side. The structured surface may preferably be provided with a serrated structure. By structuring the surface, the deformability of the support can be additionally controlled. By different shaping, for example, the point (pointed or less acute triangular structures or deep or less deep structures) can in the manufacturing process targeted a desired Deformability of the support can be adjusted for a given plastic material.

A sliding door assembly according to the invention has at least one bottom profile, are arranged stationary in the support rollers, and at least one slidably guided on the support rollers such sliding sash. This results in the advantages mentioned in connection with the sliding leaf.

Fig. 1 shows a schematic partially sectioned side view of a sliding door assembly in which a sliding panel according to the application is used.

In a bottom 1, a bottom profile 20 is embedded in a recess 2, in which at regular intervals support rollers 24 are rotatably mounted stationary.

On the support rollers 24, two sliding sash 10 are placed, each having a surface element 11, in particular an insulating glass pane having. For the sake of clarity are in the Fig. 1 the sliding sash 10 is shown offset upwards.

The surface elements 11 are bordered at their lower, the support rollers 24 facing end side of each edge profile 12. At the respective three other end faces more edge profiles 13 are arranged. With regard to its cross section, the further edge profiles 13 may be the same or similar to the edge profile 12 arranged below. An edge profile 12 and three further edge profiles 13 comprise each surface element 11 as a frame, which is not self-supporting and only in conjunction with the surface element 11 has the necessary stability.

The sliding leaf 10 are placed with its lower edge profile 12 on the support rollers 24. In the upper part of the sliding leaf 10 guides are provided which prevent tilting of the sliding sash 10 from its vertical position. The sliding sash 10 can run directly on the support rollers 24 with the lower edge profile 12. Alternatively, a separate running profile, which provides the actual tread, be attached to the edge profile 12.

An according to the application sliding door assembly may have one or more such sliding sash 10. If several mutually displaceable sliding panels 10 are provided, these are arranged in different levels one behind the other, so that they can be moved past each other. Accordingly, support rollers 24 are also arranged in different, adjacent in the ground plane lines one behind the other.

Fig. 2 shows a section through a bottom profile 20 and a section of a mounted sliding leaf 10 in a further embodiment of a sliding door assembly.

In contrast to the example of Fig. 1 In the present case, only one movable sliding leaf 10 is provided, at least in the area of the illustrated sectional plane. To accommodate another sliding wing in another section of the sliding door assembly or a fixed wing two adjacent identical and mirror-inverted floor profiles 20 are still embedded in the ground, not shown here.

The two floor profiles 20 are coupled together via insulating webs 21. They are mounted by not visible in this figure anchors in a depression of the soil.

That in the Fig. 2 arranged on the right side bottom profile 20 has an inserted support roller profile 22, in which the support rollers 24 are rotatably supported by bolts 23 at regular intervals. In the upper area of the Floor profile 20 and the upper of the insulating webs 21 are longitudinally extending brushes 25 used in groove-shaped recordings, which run along the inserted sliding panel 10 along and reduce the ingress of dust in the lower region of the sliding leaf 10.

That in the Fig. 2 bottom profile 20 shown on the left is equipped without the support roller profile 22. Instead, a cover 26, which is flush with the floor, is inserted in holders, which in turn are inserted into the grooves for the brushes 25 in the base profile 20 or the insulating web 21.

The sliding leaf 10 comprises a surface element 11, which in the present case is designed as a triple insulating glass pane. The surface element 11 is bordered at its lower end side by the edge profile 12 and at its other three end faces by further edge profiles 13. The further edge profiles 13 are optionally held on the surface element 11 with a conventional adhesive or a sealant.

The edge profile 12 is substantially U-shaped, wherein the surface element 11 rests with its lower end face on a support 15 which is inserted into the U-shaped edge profile 12. Details on the design of the support 15 will be described in more detail in connection with the following figures.

Between the laterally upwardly projecting legs of the U-shaped edge profile 12 and the surface element 11, a seal 15 is inserted on each side.

In the illustrated embodiment, the support rollers 24 do not roll off directly on the edge profile 12, but on a running profile 12 ', which is arranged centrally under the edge profile 12 and screwed thereto. This arrangement offers the advantage of being able to produce the running profile 12 'from a different material than the edge profile 12. For example, a different hardness for the running profile 12' can be selected than for the edge profile 12, whereby rolling properties and also rolling noise can be influenced. In the illustrated embodiment, the support rollers 24 are provided with a V-shaped notched tread and the tread 12 'has a corresponding downwardly facing V-shaped running profile. In this way, a side guide for the sliding leaf 10 is achieved with only one row of support rollers 24.

In the Figures 3a-3d is in four different representations, a first embodiment of a support 15 for use with a sliding sash, for example, the sliding sash 10 according to Fig. 2 represented. A portion of the overlay 15 is in Fig. 3a in a supervision and in Fig. 3b reproduced in an isometric view. Fig. 3c shows a sectional view through the support 15 in a direction transverse to the longitudinal extent of the support 15th Fig. 3d gives the circled area of the Fig. 3c increases again.

In the illustrated embodiment, the support 15 consists of a band-shaped material having a web width b 'and a thickness d. This strip-shaped material runs undulating along a longitudinal direction l, which is also the direction of the longitudinal extension of the end face of the surface element 11 and the longitudinal direction in which the edge profile 12 extends. The wave structure has a repeat length l '. Due to the wave structure, the support 15 assumes a total width b, which is many times greater than the web width b 'of the material of the support 15.

The support 15 can be made of plastic in an extrusion process in the manner of a continuous material and a subsequent punching process or in an injection molding process as a rod material. With sufficient length of the rods, the support 15 can extend in one piece and continuously over the substantially entire length of the edge profile 12. Alternatively, two or more pads 15 can be inserted one behind the other in an edge profile 12, if the edge profile 12 is longer than the individual support 15. As a plastic material, for example, polyethylene (PE), polyamide (PA) or polypropylene (PP) are suitable.

The width b is chosen so that the edge profile 12 is also substantially filled in its width. The wave structure allows by upsetting or pulling apart in the longitudinal direction, a variation of the width b, whereby the illustrated support 15 can also be used for different widths of the edge profile.

The support 15 can be inserted into the edge profile 12, wherein in addition an adhesive can be used for fixing. Also, an adhesive or a sealant can be used to fill remaining areas 30, which does not occupy the support 15, and thus to establish a secure connection between the edge profile 12 and the surface element 11.

Adhesive is applied to the support 15 inserted into the edge profile 12, if necessary additionally the regions 30 being filled with adhesive or sealing compound. A thus prepared edge profile 12 is then placed on the edge of the surface element 11 and glued to the surface element eleventh

The support 15 provides in the edge profile 12 a uniform support for the surface element 11 at a plurality of support points. However, the support is not over the entire surface, which increases the pressure on the support 15 at the support points. Even when using a relatively hard plastic for the surface element 11, this leads to a sufficient deformability at the support points, so that a thickness compensation to compensate for unevenness of the surface element 11 on the front side, for example, protruding glass is guaranteed.

The number of contact points per unit length can be influenced by varying the repetition length l 'of the wave structure. The size of the support surface in a support point can be influenced by the web width b '.

In addition, the deformability of the support 15 is controlled by the fact that a structured surface 16 is provided at the top and bottom of the support 15. The structured surface 16 is particularly good in the enlargement of the cross section in the Fig. 3d to recognize. In the present case, a serrated structure is introduced. By different shaping of the teeth (pointed or less acute triangular structures or deep or less deep structures), a desired deformability of the support 15 can be adjusted for a given plastic material specifically in the manufacturing process.

In the FIGS. 4a-4d is the same as in the Figures 3a-3d a further embodiment of a support 15 shown for use in a sliding sash. In this embodiment, the support 15 is constructed of two corrugated webs extending in opposite phase or mirror image to each other.

As in the first embodiment of Figures 3a-3d are again the top and bottom of the support 15 with a textured (here jagged) surface 16 is provided. In addition to the width b 'and the thickness d of the individual undulating webs, the load-bearing capacity and the flexibility of the support 15 can also be adjusted here by varying the repeat length l' of the wave structure. To a lesser extent, but not as pronounced as in the embodiment of Figures 3a-3d , is possible by stretching and compressing in the longitudinal direction l a variation of the repeat length l 'and the width b.

The Figures 5a-5d Finally, show a further embodiment of a suitable for sliding sash 10 pad 15. In this embodiment, the support 15 is formed in a ladder-like structure and has two longitudinally extending side webs 17 and a plurality of transverse webs 18. Also in this embodiment, the load bearing capacity can be varied by varying the repetition length l 'of the structure, which here corresponds to the distance between two adjacent transverse webs 18. As in the examples presented above, the top and bottom of the support 15 are provided with a structured, in turn serrated surface 16. With regard to the materials and the possible different configurations of the structured surface 16 applies to the examples of FIGS. 4a-4d and 5a-5d that in connection with the embodiment of the Figures 3a-3d said.
