Description

The present invention relates to a track rail and a track assembly with a sliding leaf suspension and a method for producing a sliding leaf suspension.

Sliding leaf suspensions for slidably supporting sliding sashes such as window or door sashes are generally known in the art. Conventional solutions have for this purpose in particular in the field of the threshold of light metal profiles composite guide rail profiles, wherein the guide rail profiles are connected to prevent unwanted heat transfer by means of so-called insulating webs. The insulating webs are formed from a material which conducts the heat poorly, thereby reducing in particular the direct heat transfer between the guide rail profiles caused by heat conduction. In a region pointing in the direction of the sliding leaf to be hung up or to be supported, conventional sliding wing suspensions have running rails formed directly on the guide rail profiles. In turn, rollers are formed on the wings to be stored hingedly, so the window or door sliding panels or sliding wall elements, which are placed with their wheel treads on the rails of the guide rail profiles. The molded directly on the guide rail profiles rails is then a Linear guide the sliding bearing wings guaranteed during a sliding operation.

In order to keep the weight of the wings to be moved and their dimensions as small as possible, which are usually also composed of profiles sliding sash in its extension in width are limited. In particular, when the sliding panels are formed from two wing profiles, which are interconnected by means of insulating webs, the rollers for preventing unwanted rotational or tilting moments are centered between the two connected wing profiles and thus arranged in the region of the wing profiles connecting insulating bars. In order to ensure the most dense and draft-free completion of the edges of the displaceably guided airfoils, the airfoils project in this central region usually the rollers arranged there. It follows, in turn, that the width of the guide roller or guide rollers, d. H. its extension is limited in a direction perpendicular to the direction of displacement and perpendicular to the vector of the acting weight of the displaceably mounted wing. In other words, because the wing profiles project beyond the center region in the direction of the guide rail profiles, the roll width can not be increased arbitrarily without the outer edges of the roll or rollers touching the inner walls of the wing profiles in a disturbing manner.

By largely based on these reasons, determination or limitation of the maximum width extension of the rollers is also substantially the profile distance between the guide rail profiles, d. H. for example, given the embedded in the threshold door profiles.

Significant unwanted heat transfer between the guide rail profiles is carried out in three main ways, namely heat conduction, heat radiation and convection. In particular, to reduce the unwanted heat transfer due to heat conduction and heat radiation, it would now be desirable to increase the profile distance between the guide rail profiles and to increase the length of the insulating strips connecting them. In the case of conventional sliding leaf suspensions, it is disadvantageous that such an enlargement of the guide rail profile spacing is not possible without undesirably increasing the width of the roller or rollers.

The document FR 2 771 129 A1 shows a known track with a tread for supporting a roller of a sliding wing assembly, wherein the running rail has two connected by insulating webs metal guide rail profiles. The present invention was therefore based on the object to provide a solution with which for a given roller width of the unwanted heat transfer between the guide rail profiles can be further reduced.

This object is achieved by a track rail according to the independent claim 1, and a track assembly according to claim 6 with a first track rail according to independent claim 1 and a second track rail according to independent claim 1. Furthermore, the object is achieved by a method for producing a sliding leaf suspension according to independent claim 12.

Thus, with respect to the track rail, the track rail is for a sliding leaf suspension, the sliding leaf suspension having at least two guide rail profiles connected by insulating webs, and the track rail having at least one tread for supporting at least one wheel tread of at least one sliding leaf roller, the tread width being depends on the profile distance of the guide rails to each other.

The fact that a running rail with a tread is used, which supports a wheel tread of the roller, a secure support of the slidingly mounted wing is guaranteed. Due to the dependence of the extent of the tread on the profile width, d. H. The fact that the extent of the tread from the edge of the respective guide rail profile in the connection region of the guide rail profiles depends on how wide this connection region and thus the profile distance is, it is possible to increase the profile distance compared to conventional guide rail profiles of sliding leaf suspensions to improve the thermal properties to increase the sliding wing suspension. At the same time, the depiction of the dependence on the tread width of the profile distance and still ensures a safe and stable storage of the roller or rollers of the sliding leaf, without at the same time in an undesirable manner, the wide moderate extent of the roller or rollers, d. H. the distance between the wheel treads to each other must be increased.

With regard to the method, the object is achieved in that the inventive method for producing a sliding leaf suspension initially a method step for providing a first and a second guide rail profile having. In a further method step, the profile distance between the guide rail profiles is determined by one or more insulating webs of the appropriate length are provided and the guide rail profiles are connected to each other by means of the insulating web or by means of insulating bars. After the profile distance is fixed, then at least a first track with at least one first tread is provided, the tread width depends on the specified profile distance. After that, a first wheel running surface of at least one first roller of a sliding leaf is mounted on the at least one running surface.

Also with regard to the method, this results in the particular advantage that after fixing a desired to improve the thermal properties profile distance of the guide rail profiles to each other a running rail can be provided, which depends in relation to their tread width of this specified profile distance. The roller or rollers can then with respect to their Radlauffläche or Radlaufflächen whose distance fixed to each other in advance or at least only to a limited extent can be fixed in advance, be securely stored by the appropriate adjustment of the tread width even at a profile distance, which is larger than usual is.

Advantageous developments are specified in the subclaims. Thus, it is provided with respect to the running rail, for example, to choose the tread width the larger, the farther the profile distance. In other words, when determining a relatively large profile distance between the guide rail profiles, a relatively large tread width is to be selected. Then it is possible to ensure a secure supporting the roller or rollers even with a relatively wide profile distance.

Furthermore, it is provided with respect to the running rail, that the running rail has a wreath stop for a wheel flange formed on the roller. Such a flange then allows when moving the sash and thus during a rolling movement of the roller through the mediated by the wreath guide property good lateral guidance of the sash, which contributes to increased smoothness.

To further improve the Lateralführungseigenschaften also a Lateralführungsfläche is provided on the running rail, which the lateral guide a Lateralführungsrolle the sliding sash is used. As a result, the stability during the sliding process can be improved again.

According to a further aspect of the invention, it is provided that in relation to the running rail, the running surface width depends on the profile spacing of the guide rail profiles relative to one another such that the sliding leaf is mounted so as to be displaceable substantially centered between the guide rail profiles. In other words, with known fixed width of the roller, d. H. at a known and fixed distance of the wheel treads to each other, the running surface width of the track selected such that in relation to the relative position of the guide rail profiles to each other, the roller or rollers are guided centrally between the connected profiles, so that also substantially in its central region with the roller or sliding wheels connected to the rollers is guided centered between the guide rail profiles.

With regard to the rail arrangement according to the invention, it is provided that such a rail arrangement is equipped with at least one first running rail described above and at least one second running rail described above. In order to obtain the track arrangement, the first track is arranged on the first guide rail profile of the interconnected guide rail profiles. Similarly, the second track rail is arranged on the second guide rail profile of the connected guide rail profiles. In this case, it is possible for two rails identical in their cross-section to be provided in mirror-symmetrical cross-section with respect to the connecting region of the rail arrangement. As a result, a particularly simple structure and a simple centering of the slidingly mounted wing with respect to the guide rail profiles are guaranteed.

With regard to the rail arrangement, it is provided according to a further aspect of the invention that a track width is determined by a corresponding shape and arrangement of the first and the second rail to each other by the distance of the respective running surfaces to each other. In a corresponding manner is determined by a roller, which has at least two Radlaufflächen, by the distance between these two wheel treads to each other a track gauge. In this case, for a given track gauge, the track width becomes for bearing the two running surfaces on the respective wheel treads selected such that the running track width substantially corresponds to the track gauge. In this way, in the event that a single roller with two treads is used, a good leadership property and in particular a largely schlingerfreies moving the sash guaranteed.

In an analogous manner with respect to the track arrangement in a determination of the track width defined above by the distance of the running surfaces of the first and the second track to each other provided that when at least a first and a second roller are provided and the first roller a first wheel tread has, and the second roller has a second Radlauffläche, the distance of the first to the second Radlauffläche each set a track gauge. In this case, the track width for supporting the wheel treads on the two treads is selected in an analogous manner such that it corresponds to the track gauge substantially. This results in an analogous manner when at least two rollers, preferably on a single axis, are provided to ensure a relatively smooth and schlingerfreies moving the sash.

Furthermore, it is provided with respect to the track assembly, that when a first and a second track, each with a Lateralführungsfläche are used by shaping and arrangement of the rails by the distance of Lateralführungsflächen each other a lateral guidance is further defined, with respect to the Diameter of Lateralführungsrolle the Lateralführungsweite substantially corresponds to this diameter. As a result, a further improved Lateralführung is ensured, which is associated with increased smoothness when the sliding sash is moved.

In a preferred manner, it is provided that the Lateralführungsweite is smaller than the track width. In this case, a lateral guide roller with a relatively small diameter can be used, which means a cost savings.

In accordance with a further aspect of the invention, it is further provided with respect to the track arrangement that the at least one first track, the at least one second track, or both the at least one first and the at least one second track on the first and on the second guide rail profile is preferably attached by clipping.

Of course, however, other attachment methods such as an adhesive bond come into consideration. This makes it possible, in particular, to introduce the rails into their destination only after the installation and assembly of the guide rail profiles, so that during the previous assembly or installation of the guide rail profiles, a possibly necessary tool insert or the like in the region of the guide rail profiles connecting insulating webs is not hindered. By the subsequent insertion of the first track or the second track or both rails and attaching to the respective guide rail profile then a safe storage of the roller is still guaranteed.

With regard to the method according to the invention for producing a sliding-leaf suspension, according to a further aspect of the invention it is provided that at least one second running rail is provided with at least one second running surface which supports the bearing of a second wheel-running surface of at least one second running roller of the sliding leaf on the at least one second running surface Tread is used.

In this case, the first and the second running rail are shaped and arranged such that the distance between the running surface of the first running rail and the running surface of the second running rail defines a running track width. By the distance of the first to the second Radlauffläche each other a running track gauge is set in an analogous manner. In this case, the track width for supporting both wheel treads on the respective treads is then selected such that it corresponds to the running track gauge substantially.

In the following, two embodiments of the solution according to the invention are explained in more detail with reference to a drawing.

Fig. 1:

a sectional view of a sliding leaf suspension of interconnected guide rail profiles with a running rails equipped with rails according to the invention; and

Fig. 2:

a sectional view of a sliding leaf suspension similar Fig. 1 , with a larger profile distance.

Fig. 1 shows a sectional view of a sliding sash suspension of a first guide rail profile 10 and a second guide rail profile 20, which are interconnected by means of two insulating webs 31, 32. The guide rail profiles 10, 20 are made of metal, preferably made of light metal such as aluminum. In order to minimize unwanted heat transfer between the guide rail profiles 10, 20, the insulating webs 31, 32 are made of a poorly heat-conductive material, such as a hard plastic.

Schematically in Fig. 1 also shown is a sliding wing to be stored consisting of a first airfoil 30, a second airfoil 40 and two the airfoils 30, 40 connecting insulating webs 31, 32. The representation of the consisting of the airfoils 30, 40 sash should only clarify the β-ratios. For this reason, the details of the connection between the sliding sash and a bearing block of a first roller 51, a second roller 52 and a lateral guide roller 53 are not explicitly shown. It becomes clear Fig. 1 However, that both the first airfoil 30 and the second airfoil 40 project beyond the rollers 51, 52 in the outer region relative to the roller axis, ie extending in this area in the direction of the guide rail profiles 10, 20. For this reason, the distance between a wheel tread 55 of the first roller 51 to a wheel tread 55a of the second roller 52 is not arbitrarily large, without the side walls of the rollers 51, 52 would collide with the side walls of the airfoils 30, 40.

The distance of the wheel treads 55, 55a from one another is understood to be a suitable measure, such as, for example, the center distance of the respective wheel treads 55, 55a from one another.

The rollers 51, 52 are mounted with their respective wheel treads 55, 55a on the running surfaces 65 and 65a of a first running rail 61 and a second running rail 62. The first running rail 61 is in this case attached to the first guide rail profile 10, for example by a Einklipslösung. Similarly, the second track 62 is attached to the second guide rail profile 20, for example by clipping.

For lateral guidance, both the first roller 51 and the second roller 52 each have inner flanges 56 and 56a analogous to the wheelset a rail vehicle, which rest against corresponding wreath stops 66, 66 a of the first running rail 61 and the second running rail 62 for tracking. The rim spacing of the flanges 56, 56a to one another defines the track gauge s and is substantially fixed by the limited widthwise extension of the roller block described above. The distance of the wreath stops 66, 66a of the first running rail 61 and the second running rail 62 to one another accordingly defines the running track width w and, within a certain tolerance range, essentially corresponds to the running track dimension s. In order to ensure a secure bearing of the rollers 51, 52 on the rails 61, 62, the tread width I, which is defined in the illustrated embodiment by the distance of a mounting portion 68 and 68a to the corresponding wreath stop 66 and 66a, set. Depending on the choice of the profile distance p, which is made on the basis of thermal considerations, the running surface width I of the first running rail 61 and the second running rail 62 is accordingly dependent on the profile distance p in order to ensure a secure mounting and linear guidance of the rollers 51, 52 the running track width w with respect to the running track dimension s which is predetermined is selected accordingly.

In order to improve the lateral guiding properties, ie to reduce unwanted slings, a lateral guide roller 53 is additionally provided, which is in contact with lateral guide surfaces 67, 67a of the first running rail 61 and the second running rail 62, respectively. By the distance of the lateral guide surfaces 67, 67a of the first track rail 61 and the second track rail 62 to each other thus the Lateralführungsweite f is defined, which in the illustrated embodiment according to Fig. 1 is less than the track width w. Depending on the accuracy of fit, it is conceivable that the lateral guide roller bears against only one of the lateral guide surfaces 67 and 67a and executes a retraction movement laterally supporting the sliding leaf during a displacement operation or glides between the lateral guide surfaces 67, 67a of the rails 61, 62.

In order to achieve a further improved thermal separation between the first guide rail profile 10 and the second guide rail profile 20 in accordance with existing installation space is in the in Fig. 2 shown second embodiment of the profile distance p by correspondingly longer selected insulating bars 31, 32 with respect to the embodiment according to Fig. 1 increased.

In contrast, the track gauge s or the track width w compared to the embodiment according to Fig. 1 remained the same, and the tread width I of the according to the embodiment in Fig. 2 used for running rails 61, 62 has also been increased depending on the larger profile distance p. In this way, it is thus possible, even with an increase in the profile distance p by appropriate adjustment of the rails 61, 62 one and the same roller block consisting of first roller 51, second roller 52 and lateral guide roller 53 with fixed track gauge s independent of the profile distance p use.

Likewise, from the comparison of the two embodiments of the FIGS. 1 or 2 clearly that as the profile distance p increases the tread width I as well. Both in the first embodiment according to Fig. 1 as well as in the second embodiment according to Fig. 2 In this case, the sliding wing consisting of the wing profiles 30, 40 and the insulating webs 31, 32 with respect to the connection region of the guide rail profiles 10, 20 is substantially centered, that is mounted and guided centrally displaceable.

With the solution according to the invention, it is possible, despite predetermined small Laufspurmaßes s of the rollers 51, 52 use the same roller blocks with a fixed track gauge s for different profile distances p. As a result, depending on the available installation space, the optimum profile distance p from the thermal point of view can always be selected without the roller block having to be adapted in a complex manner. Instead, it is possible to dimension only the rails 61, 62 correspondingly, so that a running track width w substantially corresponding to the track gauge s is ensured. Due to the possibility of only subsequent installation of the rails 61, 62 also easy accessibility of the connecting portion of the guide rail profiles 10, 20, for example, during installation of the same, guaranteed.
