Description

The invention relates to a sliding sash frame of two by at least one insulating web interconnected profiles made of light metal and in particular a sliding window or sliding door frame of two interconnected by at least one insulating bar extruded aluminum profiles.

Such sliding sash frames, which are composed of profiles are basically known from the prior art. The light metal profiles, i. In particular, the extruded aluminum profiles such sliding sash frame while have excellent optical and mechanical properties, however, have the disadvantage of conducting the heat relatively well. Especially with a strong temperature gradient, for example, between the inside of the building facing profile of the sliding sash frame and the weather side facing profile of the sliding sash frame, therefore, an undesirable heat transfer is reduced by the fact that the individual profiles, i. the building inside facing profiles and the weather side facing profile, by means of insulating webs of a stable, the heat poorly conductive material such as hard plastic are interconnected.

When standing mounted sliding sash frame, ie when in installation position on a lower rolling or sliding upright sliding sash frame, is then above this connection area in which the profiles by means of at least one Isoliersteges are interconnected, a surface element such as a glazing provided; and below the connection region, ie below the lowermost insulating web in the presence of several insulating webs, then the rolling or sliding device is provided with the associated rolling or sliding element, which is fastened by means of a suitable fastening means, for example by means of a screw, usually on the lower insulating web.

The rolling or sliding element of the rolling or sliding device is then mounted on a guide element, for example a guide groove of a running rail, wherein the running rail is already part of a fixed frame element such as a frame profile.

Such conventional sliding sash frames have the disadvantage that relatively large space must be provided between the surface element to be guided, such as the glass sheet and the rolling or sliding of the rolling or sliding device, i. the extension in the direction of support of such conventional sliding sash frame is relatively large. This in turn results in the one hand, a large material consumption of light metal for the large extent of the interconnected profiles; On the other hand, such a large extent also has thermal and optical disadvantages.

Fig. 1 shows a conventional sliding sash frame 110 according to the prior art, which is composed of a first profile 111 and a second profile 112, which are interconnected by means of a first insulating bar 121 and a second insulating bar 122. A surface element 120, for example a glazing, is in the installed position in Fig. 1 illustrated prior art sliding sash frame 110 according to the prior art supported in the upper region. Directly below it is followed by a connection region in which the insulating webs 121 and 122 connect the two profiles 111, 112 thermally separated with each other. A conventional sliding or rolling device 150 has a roller 151, which cooperates with a guide groove 116 of a running rail 117 and allows a displacement of the conventional sliding frame 110 perpendicular to the plane of the drawing. In the conventional solution according to the prior art, as in Fig. 1 is a fixing of the conventional sliding or rolling device 150 at the lower first Isoliersteg 121 necessary, which is usually done by means of a screw 113.

By this necessary attachment results in a relatively large height H1, which corresponds to the distance between the lower insulating web 121 and the guide 116. This makes it necessary that the profiles 111, 112 also have a relatively high height. The profiles 111, 112 are usually made of extruded aluminum, resulting in a relatively large amount of material through the relatively large height H1 and the production cost of the profiles 111, 112 increases.

The EP 1 772 582 A1 discloses a sliding sash assembly according to the preamble of claim 1 of two profiles connected by insulating webs. There is provided a multi-level rolling device, which projects at least partially into the region of the insulating web connecting the profiles and supports a sliding door frame by means of the roller of the rolling device on a running rail. In whose in the EP 1 772 582 A1 disclosed solution is the multilevel trained rolling device is only loosely inserted in their receiving area between the connected profiles and is held. Regarding. Their degree of freedom perpendicular to the ground plane only in the assembled state by the contact between the guide rail and the roller of the rolling device. An assembly of the profile arrangement suburb is thus relatively cumbersome because additional fixing means are required for fixing the rolling device for the purpose of installation.

The present invention has the object of developing a conventional sliding sash frame to the effect that the required space and thus the necessary material consumption can be reduced.

The object is achieved by a sliding sash frame according to independent claim 1.

The inventive solution has over conventional sliding sash frame a number of advantages: The fact that the sliding or rolling device, which takes over the guided displaceable mounting of the sliding sash frame in a fixed frame part, ie in particular a guide groove of a running rail of a fixed frame part, at least partially into one Opening of the at least one insulating web is added, the necessary space, ie the distance between the contents held in the sliding leaf frame surface element and the upstanding on the guide member or with the guide member engaged part of the sliding or rolling device can be reduced. In other words, in installation position of the sliding sash frame the required height, which corresponds to the distance between the salient Flächenfläche element and the groove of the guide rail reduced. This also reduces the required amount of light metal, ie in particular extruded aluminum, for the profiles.

It should be noted that the term "picking up" of the sliding or rolling device in the opening or "at least partial picking up" of the sliding or rolling device means an at least partial locking. By recording at least the mechanical degrees of freedom of the sliding or rolling device in the direction of displacement and relative to the ground plane in the installation direction are reduced transversely thereto, without affecting the displacement possibilities of the sliding sash frame.

Advantageous developments of the solution according to the invention are specified in the dependent claims.

For example, it is provided that at least one of the profiles has at least one contact element for at least partially fixing the sliding or rolling device.

This makes it possible to restrict another degree of freedom, namely in the installed position perpendicular to the ground plane of the sliding sash frame.

This results in the further particular advantage that further fixation elements such as screws or the like can be saved by this simple form of fixing the sliding or rolling device, which additionally reduces the material, but also the workload.

Advantageously, during an assembly process, i. when at least partially inserting the sliding or rolling device in the opening, initially this insertion process terminated to then bring parts of the sliding or rolling device with the at least one contact element in engagement. As a result, an insertion or assembly process is easily possible.

According to a further aspect of the invention, it is provided that the sliding or rolling device is flexible at least in some areas.

In question here is to form a complete outer wall of the sliding or rolling device made of flexible material, so that it can be compressed as a whole. Alternatively, it is also possible, latching noses or the like, for example, which are engaged with the contact elements on the at least one of the profiles, foldable form by appropriate flexible design, so as to simplify the assembly process. The sliding or rolling device can then be inserted at least partially into the at least one opening; subsequently or at the same time during this at least partial insertion, the compression of at least parts of the sliding or rolling device takes place in order to complete the assembly progress.

According to the invention it is provided that the sliding or rolling device has a fitting area and a functional area. The cross section of the fitting region substantially corresponds to the opening cross section of the at least one opening, i. it is formed substantially complementary to the opening cross-section of the at least one opening.

In the case of advantageously rectangular opening cross sections, the width of the fitting area thus corresponds approximately to the opening width, while the length of the fitting area corresponds approximately to the opening length. In accordance with at least partially flexible design of the fitting portion, however, it is also possible to form it such that its outer walls after an insertion process (at least partial insertion) in the at least one opening largely tightly against the walls of the at least one opening. This prevents that any run-off rainwater or condensation water in this area between the wall of the opening and wall of the fitting area penetrates and leads to stagnation-related aging phenomena.

According to a further aspect of the invention it is provided that the at least one opening is additionally designed as a drainage opening, and that the sliding or rolling device is constructed such that it allows at least partially a passage of liquid.

In an advantageous manner, such a sliding or rolling device permitting a passage of liquid at least in some areas is in turn constructed such that it has a fitting area and a functional area. Such a at least regional passage of liquid can be made possible, for example, by the sliding or rolling device being at least partially hollow in the installed position from top to bottom, the rolling or sliding element (usually a roller) being held centrally in the passage opening. A drainage of liquid is thus easily possible by passing through the at least one opening, passage through the sliding or rolling device and then drainage in the region of the guide rail.

Another advantage of this development is that no additional steps for the attachment of additional drainage openings are required if the at least partially receiving the sliding or rolling device suitable at least one opening simultaneously serves as a drainage opening.

According to a further aspect of the invention it is provided that the sliding or rolling device is constructed in several pieces. Preferably, the sliding or rolling device is formed in this context in two pieces. As a result, the assembly process is further simplified. First, therefore, a first piece of sliding or rolling device ("adapter") is used in the profile composite of profiles and insulating bars. It is not essential that this adapter piece is already at least partially inserted into the at least one opening. Rather, it can also be provided that this adapter piece is applied only to the at least one contact element. Subsequently, the further piece of preferably two-piece sliding or rolling device is then attached to this adapter piece, this further piece is then at least partially inserted into the at least one opening. Furthermore, both pieces are in a particularly preferred manner in relation to acting forces in relation, so that the adapter piece intercepts occurring loads, while the other piece contains, for example, the rolling or sliding element and in addition at least partially inserted into the at least one opening that, for example, a Drainage is ensured.

In a preferred embodiment of the solution according to the invention the sliding or rolling device is formed in two pieces, wherein an insert of the sliding or rolling device is adapted to cooperate with the at least one contact element. The insert of the sliding or rolling device in this case has a guide element, in particular a guide rail, said guide element is adapted to cooperate with a counter-guide element, in particular a counter-guide groove which is present on a functional piece of the sliding or rolling device.

In other words, the insert and the functional piece together form the sliding or rolling device, but can be mounted separately. On the functional piece here is the rolling or the sliding element, so usually provided the role. By such an "adapter solution" fitting, i. Installation at the installation site, further simplified.

It should be understood that the guide element of the insert is of course not limited to a one-sided guide element, i. in particular also that, for example, a guide rail or the like can be provided on several sides of the insert piece. Instead of a guide rail, other guiding or locking elements are possible.

For the interaction of the insert of the sliding or rolling device with the at least one contact element of the profiles are, for example, clamping elements such as clamping lugs or the like.

According to a further aspect of the invention it is provided that a plurality of openings is provided in each case for partially receiving in each case a sliding or rolling device. Preferably, in this case at least one opening in a first edge region of the sliding sash frame and at least one further opening in a second edge region of the sash frame are provided. In this context, "edge region" is understood to mean a region which is arranged in the expansion direction (usually the extrusion direction) of the profiles in relative proximity to the end-side end surfaces.

This makes it possible to ensure a relatively homogeneous mounting of the sliding sash frame on the guide element, in particular thus on the guide groove of the running rail.

In the following, the solution according to the invention is explained in more detail with reference to a drawing.

Fig. 2a shows in a schematic sectional view also a cross section analogous to the illustration Fig. 1 , but here for a sliding leaf frame 10 according to a first illustrative example, which is intended only to understand the embodiments of the invention.

Again, a surface element 20 in the area shown in the installation position above Fig. 2a held between a first profile 11 and a second profile 12, wherein the profiles 11, 12 are formed of light metal, in particular of extruded aluminum and are connected to each other by means of two insulating webs 21, 22 of a thermally poorly conductive material such as hard plastic.

In Fig. 2b is in a sectional view in a plane which is parallel to the ground plane Fig. 2a in the explanatory example according to Fig. 2a underlying second insulating web 22 is shown, which has an opening 25 with a rectangular opening cross-section and an opening width BO and an opening length LO.

As from the illustration in Fig. 2a is further apparent, in turn, below the connecting region, ie below the region in which the profiles 11, 12 are interconnected by means of the insulating webs 21, 22, a guide element in the form of a guide groove 16 of a running rail 17 is provided, said guide groove 16 and the running rail 17 already belong to stationary arranged frame profiles. The slidable mounting of the sliding sash frame 10 is in turn by a sliding or rolling device 50, in Pictured embodiment according to Fig. 2a a rolling device 50 with a roller 51 guaranteed. The roller 51 is in this case with the guide groove 16 of the running rail 17 in conjunction, so that a displacement of the sliding sash frame 10 is ensured.

As shown in the illustration Fig. 2a 1, the rolling device 50 is partially inserted into the correspondingly formed opening 25 in the insulating web 21, whereby the overall height H2, ie the distance from the lower insulating web 21 to the guide groove 16 of the running rail 17 is reduced.

As is apparent from the perspective view belonging to the first explanatory example Fig. 3a and the presentation Fig. 3b can be seen, has the appropriately trained rolling device 50 according to the first Explanatory example, a rotatably mounted roller 51, which is enclosed in a hollow housing, rotatably mounted. The housing has a special shape and is formed of a flexible material.

The housing of the rolling device 50 in this case has a fitting region 52 and a functional region 53. The fitting portion 52 has a rectangular opening cross section of the length LR and the width BR, which corresponds approximately to the opening cross section of the opening 25 in that the width BR and the width BO and the length LR and the length LO correspond such that an insertion of the fitting portion 52 is made possible in the opening 25. In the transition region between the fitting region 52 and the functional region 53, the functional region 53 is widened in its cross-section in such a way that it is made more difficult or impossible for the rolling device 50 to be pushed through the opening 25.

Because the housing, that is to say in particular the fitting region 52, is at least partially flexible, this fitting region can be inserted into the opening 25 in a simple manner and closes with the walls of the opening 25 largely tightly. In other words, penetration of water into the contact area between the fitting portion 52 and the walls of the opening 25 is made difficult; To that effect, a passage of water through the rolling device 50 in the central area is easily possible. This ensures that moisture-related aging phenomena by waterlogging in the connecting region between the fitting portion 52 and the walls of the opening 25 is largely prevented.

The functional area 53 has such a shape that it bears flush against contact elements 13, 14 which are formed on the profiles 11 and 12, respectively. In this way, a secure locking of the rolling device 50 is achieved without the need for additional fasteners such as screws or the like.

In the second explanatory example of FIG Fig. 4a and 4b It can be seen that such areas of the functional area 53 of the rolling device 50 abutting against the abutment elements 13, 14 can also be formed from flexibly formed clamping lugs 59, which simplifies an assembly process of the rolling device 50 on the sliding-leaf frame 10.

According to a first embodiment Fig. 5a and 5b it is possible, the rolling device 50 in several pieces, in the illustrated first embodiment in two pieces, from an insert 55 and a functional piece 56 form. At the insert piece 55, a guide rail 57 is provided, which engages in the joining of insert 55 and functional piece 56 with a correspondingly formed on the functional piece 56 complementary to the guide rail 57 guide groove 58 into engagement.

By this multi-piece construction of the assembly process can be further simplified. First, for this purpose, the insert 55 is inserted into the sliding frame 10 so that it rests against the correspondingly formed contact elements 13, 14 of the first profile 11 and the second profile 12 position-locking. Subsequently, the functional piece 56 is pushed into the insert 55 up to a stop 60 and locked with its fitting portion 52 in the opening 25. This embodiment ensures a particularly safe and simple deployment process and reliable locking of the rolling device 50 in the sliding leaf frame 10th

Fig. 6a and 6b show an alternative embodiment of the inventive solution according to a second embodiment. Again, the rolling device 50 is formed in two pieces and consists of an insert 55, in which a functional piece 56 is used, wherein a fitting portion 52 is inserted into a correspondingly shaped opening 25.
