Description

frame assembly

The invention relates to a frame assembly having at least one door and / or window profile, which has at least one hollow chamber, with a rebate base, with at least one outer flashover and with at least one arranged on the outer arcing sealing element.

Such frame assemblies are widely known and described in the prior art. Thus, such frame assemblies are made of door and / or window profiles in a conventional extrusion or coextrusion process and produced to known windows or doors by, for example, welding mitred corners.

The door and / or window profiles generally have an external flashover, on which a sealing element is arranged, which after welding the door and / or window profiles to frame assemblies, a brought into the frame surface carrying member relative to the door and / or Window profile sealingly framed.

In the course of the production of such well-known frame assemblies made of, for example, PVC materials in window, door and façade construction, it is known to cut off the length and cut with respect to their front sides mitred door and / or window profiles to the respective Miter joints first with a welding mirror plasticize. Depending on the wall thickness and spatial form of the door and / or window profiles, this process takes a certain time at temperatures of, for example, about 250 to 270 ^° C. After plasticizing, the welding mirror is removed from the opposite door and / or window profile end faces and becomes it then the plastified end faces of the door and / or window profiles welded together under a defined pressure in a certain time pressed against each other. This inevitably produces extruded so-called. Welding beads that are everywhere removed by, for example, cleaning, milling, peeling or cutting, where it is necessary for reasons of appearance and / or for proper positional fixation of the sealing elements. In this way, sealing elements, for example, can then be continuously embedded in corresponding receiving grooves of the door and / or window profiles via their anchoring feet over the miter joints.

In this method for the production of frame assemblies so far sealing elements made of elastic materials have been used in the vast majority. In many cases, however, it had been found that the welding beads formed in the area of the receiving grooves as a result of the plastification of the plastified end faces of the door and / or window profiles take on a knife-like character and thus can sever the sealing elements at their miter joints, for example. The negative consequences are leaks of the relevant frame assemblies with the associated known disadvantages.

Another method for producing such frame assemblies is described in DE 19644183. In this method and the device described, the elastic function of the seals to be welded in the area of the mitred corner with the door and / or window profiles should be preserved.

For this purpose, it is provided, for the period of welding the door and / or window profiles and the seals, the inner contour of the seal formed by the sealing lip and the mounting foot of the seal in and adjacent the miter plane by at least one molding, a so-called or cover almost contour-right and the molded part is moved away from the region of the sealing elements after the welding.

This covering of the inner contour of the sealing elements in the miter area with an additional molded part during welding of the door and / or window profiles is intended to prevent the formation of a weld bead, in particular in the interior region of the seal, which adversely affects the elasticity of the sealing element, especially in this area ,

A disadvantage of this method is seen in the production of per se known frame assemblies arranged in the door and / or window profile sealing elements by additional both the equipment for the production of the frame assemblies and the frame assemblies themselves more expensive elements such as seal hold, cutting allowances or cutting hold during the individual processing steps must be kept. It is disadvantageous because for each three-dimensional shape of a sealing element or a door and / or window profile separate seal holddown, cutting allowances or cutting hold down produced kept in stock or assembled and dismantled for the corresponding operations. In addition to the error sources resulting from incorrect assembly, this more expensive in particular the process of manufacturing the known frame assemblies.

Another disadvantage is seen in the fact that by the positive guidance of the sealing elements in the production of the frame assemblies, which should be absolutely tight especially in the miter area, this can only be achieved by using sealing elements of thermoplastic, that is weldable materials. These are to allow in conjunction with the complex additional seal holders, cutting allowances or cutting holders that especially in the miter area, the sealing elements are to be firmly welded together konturgerecht, this time again consuming and specific for each sealing element welding allowances are additionally required.

This is where the invention, which has set itself the task to produce per se known frame assemblies economically and inexpensively, the material and geometry independently connected to each other with known welding machines and have in the miter area a legal requirements sufficient tightness.

This is achieved by the characterizing features of claim 1 and claim 2 according to the invention.

Further advantageous embodiments are described in the subclaims.

The frame assembly having at least one door and / or window profile, which has at least one hollow chamber, with a rebate base, with at least one outer flashover and at least one arranged on the outer arcing sealing element according to the invention is characterized in that between the rebate base and the sealing element at least partially supporting support member is formed.

Surprisingly, it was recognized that the sealing element is supported or held during the welding of the door and / or window profiles to frame assemblies by the arrangement of a sealing element partially supporting the retaining element and thus the sealing element is welded in the miter area contour-right. In a further embodiment of the frame assembly according to the invention with at least one door and / or window profile, which has at least one hollow chamber, with a rebate base, with at least one outer flashover and with at least one arranged in the outer overlap groove for receiving sealing elements, wherein the groove is approximately orthogonal to Falzgrund is arranged according to the invention is characterized in that between the rabbet base and the sealing element, this at least partially supporting support member is arranged.

Due to this embodiment according to the invention, no additional special components in the welding machines or in the cutting machines are required in the production of per se known frame assemblies made of door and / or window profiles. The setup costs of such machines as well as the storage and storage of additional elements such as seal retainers, cutting allowances, blanking or welding allowances are no longer required.

Another advantage of the frame assembly according to the invention is seen in the fact that sealing elements can now be used for the frame assemblies known per se, which can be made both from weldable, but also from non-weldable material. The inventively designed frame assembly, it is thus surprisingly possible to ensure the required tightness geometry and material in the miter area of the door and / or window profiles at any time, with significantly reduced manufacturing and machinery costs.

It has also been found to be advantageous that the Hatte element has a smaller pointing in the Falzgrund expansion than the sealing element, thereby it is advantageously possible to ensure the support of the sealing element with sufficient tightness of the frame assembly material-specific and geometry-independent. The sealing element of the frame assembly according to the invention projects slightly beyond the retaining element, so that when fabricating the frame assembly by welding the end faces of the door and / or window profiles, the surface contact elements arranged in them rest completely on the retaining elements while at the same time being tightly sealed by the sealing elements.

In a further advantageous embodiment, the frame assembly according to the invention is designed so that the distance between the height of the sealing element and the holding element corresponds approximately to half the wall thickness of the orthogonal to the rebate base arranged outer rollover.

- A - Furthermore, it has been found to be advantageous that the holding element consists of a harder material than the sealing element, so that in addition to the supporting effect of the sealing element during welding, the holding element itself is welded in the miter area and thus additionally guides or supports the sealing element in this critical area.

In a likewise advantageous embodiment, the frame assembly according to the invention is designed such that the retaining element has at least one second retaining element arranged approximately orthogonally to the rabbet base. By this example, at right angles to the holding element arranged second holding element can be positioned on the rollover additional fasteners, terminal strips or reinforcing elements and the like, which can thus be designed again structurally simple and thus cost-effectively.

A further advantageous embodiment of the frame assembly according to the invention is designed so that the holding element is spaced from the groove or the seal, so that when used as a frame assembly, the sealing element can nestle sealingly in this intermediate space forming between the surface support member and the holding element and for example when using multi-lipped sealing elements, the seal is formed optimally in particular to the surface support element.

It is further advantageous seen in the frame assembly according to the invention that the holding element is integrally connected to the door and / or window profile. As a result, an optimal and cost-effective production of the door and / or window profiles is realized, which are later connected to each other without additional machine or machine elements to frame assemblies.

Furthermore, it has been found advantageous that the holding element is integrally connected to the door and / or window profile, wherein this connection can be made both during production, but also subsequently by suitable methods such as gluing or welding.

In a further advantageous variant, the retaining element is non-positively connected to the door and / or window profile, wherein the retaining element may be formed, for example, as a web and is subsequently introduced into an example, additional groove in the outer arc. Thus, for the frame assembly according to the invention, each shape and geometry of the sealing elements can be supported by appropriately dimensioned holding elements.

The frame assembly according to the invention may advantageously be designed so that the holding element is formed as a groove which abuts the sealing element supporting the geometry and the hollow chamber in the outer flashover correspondingly extended and so contributes to additional positive thermal insulation effects of the frame assembly. In another similarly designed embodiment, the holding element is designed as a hollow chamber, on the one hand enables a supporting effect for the sealing elements of the frame assembly and on the other hand can be used as a receiving space for fasteners, but also as an additional insulating hollow chamber of the frame assembly.

In certain requirements on the geometry and spatial shape of the door and / or window profiles, the frame assembly according to the invention may be formed so that the holding element is formed as a thickening or bead.

The invention will now be described in more detail with reference to these non-limiting embodiments. Show it

The retaining element 15 supports a free end of the sealing element 14 facing the rabbet base 11, the one free end of the sealing element 14 projecting slightly beyond the retaining element 15.

Between the sealing element 14 and the profile strip 17, a surface supporting element 3 is arranged, which is formed for example as a known per se laminated glass pane. The sealing element 14 serves to dissipate moisture accumulating on the outside of the frame assembly 1, for example, by rain from the surface-supporting element 3 via the sealing element 14 and the outer contour of the outer over-lap 12. The second holding element 35, which is arranged at right angles to the holding element 15 in this exemplary embodiment, serves in this exemplary embodiment to position or fix additional connecting elements on the inner wall of the outer overhang 12.

In the manufacture of a frame assembly 1 according to the invention from mitred to the end faces and to be welded window profiles 10, the holding member 15 supports the sealing member 14, so that when welding the window profiles 10, the sealing element 14, which consists in this embodiment of a thermoplastic material over its entire contour is welded to the opposite sealing element 14 and thus leads to an optimal tightness of the frame assembly 1. 2, a further embodiment of a frame assembly 1 according to the invention is shown. The frame assembly 1 consists of a known window profile 10, which is designed as a frame, and a window profile 20, which is designed as a sash.

Introduced by the curling known per se, in which the foot 18 of the sealing element 14 in the hinterschittig trained groove 13 is pressed and this engages behind frictionally. From the groove 13 spaced on the rabbet base 11 facing free end of the sealing element 14, a holding element 15 is arranged, which is connected in this example cohesively with the outer flashover 12. Between the groove 13 and the holding element 15, a further groove 19 is arranged in the outer flashover 12 of the window profile 10, which is formed as an additional receptacle for the sealing element 14.

The holding element 15 is formed in this embodiment, that it projects beyond the sealing element 14. At the free end of the holding element 15 pointing in the rabbet base 11, a second holding element 35 is arranged, which in this embodiment fixes a connecting element 40 which is arranged on the inside of the outer overlap 12 and the rabbet base 11.

On the window profile 10, which is designed as a frame, another window profile 20 is arranged, which is designed as a sash.

The window profile 20 has an outer rollover 22, a rabbet base 21, an inner rollover 28, a profile strip 27 and a surface support element 3. At the Falzgrund 21 facing inside of the outer flashover 22, a sealing member 24 is disposed in a groove 23. The sealing member 24 is integrally connected in this embodiment in a conventional method of coextrusion with the groove 23 of the window profile 20.

The outer flashover 22 has a plurality of hollow chambers 26. At the Falzgrund 21 facing free end of the sealing element 24, a holding element 25 is arranged, which is formed in this embodiment as reaching into the Falzgrund web-like thickening. The holding elements 15, 25 of the window profiles 10, 20 support the sealing elements 14, 24 and consist of a harder material than the sealing elements 14, 24, which consist of known soft elastic materials. When welding the miter-cut end faces of the window profiles 10, 20 is a fixing and supporting the sealing elements 14, 24 such that the thermoplastic sealing element 14 welded over its entire contour and the window profile 10 seals in the frontal corner area, while a non-thermoplastic processable material produced sealing element 24 is formed by the welded holding member 25 both supported and sealingly pressed against each other.

In this embodiment, the distance between the height of the sealing element 14 and the holding element 15 corresponds approximately to half the wall thickness of the rabbet base 11 of the window profile 10 facing outer overhang 12th
