Description

The present invention relates to a Glasfalzeinlage for insertion into a Glasfalz a window or door leaf, wherein the Glasfalzeinlage a support plate and at least one longitudinal wall spring element which is arranged in the region of one of the longitudinal walls on the support plate and the Glasfalzeinlage in the inserted state in Glasfalz between two clamping profile defines the opposite profile walls of the window or door leaf comprises. In addition, the present invention also relates to a window or door leaf comprising at least one such Glasfalkeinlage.

Such Glasfalzeinlagen are from the prior art, for example from the DE 87 03 052 U1 as well as the DE 39 23 288 A1 known. Such Glasfalzeinlagen be made by injection molding of a thermoplastic material and are clamped in the Glasfalz a window or door sash profile to hold the insulator to be used in the required position in the frame. The to be bridged by the Glasfalzeinlage measure corresponds to the difference of the clear frame dimension and the level of insulating glass to be used. When inserting the Glasfalzeinlage it can not be avoided that an additional clearance must be adhered to in order to be able to absorb thermal expansion. Due to this game, however, there is a risk that about glazed during transport windows, doors o. The like. When their intended use loosening occurs, so that the stability of the frame held substantially by the glazing and the introduced voltage is impaired. For this reason, for a better grip of the Glasfalzeinlage in Glasfalz according to the DE 199 20 866 A1 the Glasfalzeinlage braced by a spring element of at least two elastic webs of a thermoplastic material, from which the rest of the Glasfalzeinlage is formed in the glazing between the walls of the profile frame. The elastic webs are integrally formed on a longitudinal wall of the Glasfalzeinlage and connected to each other via a transverse clamping web. A disadvantage of the in the DE 199 20 866 A1 described Glasfalzeinlage is considered, however, that in particular with narrow Glasfalzeinlagen a tendency exists that an erected on the Glasfalzeinlage glass block falls out in the vertical areas of the window or door leaf.

Accordingly, the present invention has for its object to provide a Glasfalzeinlage available, which overcomes the disadvantages of the prior art. In particular, in the glazing rebate insert according to the invention, the risk of falling out of the glass block set up on the glazing rebate insert should be reduced, in particular in the vertical areas of a window or door leaf comprising a glazing rebate insert according to the invention. Furthermore, the object of the present invention is to provide a window or door leaf, which comprises a Glasfalzeinlage invention.

These and other objects are achieved by a Glasfalzeinlage with the features of claim 1 and by a window or door leaf with the features of claim 7. Preferred embodiments of the present invention are described in the dependent claims.

According to the invention, it has been recognized that the falling out of the glass blocks from the respective wing, in particular in the vertical areas of a window or door leaf, can effectively prevent the glass blocks from being pressed against the planar element by the glass rebate insert. According to the present invention, this is done by the fact that the Glasfalzeinlage on its surface facing the surface element of the support plate has a spring element whose spring action acts away from the platen and thereby presses the glass block set against the Glasfalzeinlage against the surface element, which is preferably designed as insulating , In this way, falling out of the glass blocks in particular in the areas in which the glass insert according to the invention and the glass block placed thereon can fall down due to gravity than in the areas of the window or door leaf according to the invention, in which the profile rails run vertically prevented.

Accordingly, the present invention is to provide a Glasfalzeinlage for insertion into a Glasfalz a window or door leaf, wherein the Glasfalzeinlage a support plate and at least one longitudinal wall spring element which is arranged in the region of one of the longitudinal walls on the support plate and the Glasfalzeinlage in the inserted state the Glasfalzeinlage according to the invention is characterized in that the Glasfalzeinlage comprises at its groundbreaking surface of the platen facing away from the glass rebate at least one platen spring element in the glazing rebate between two opposite profile walls of the window or door leaf profile. Moreover, the present invention is also in the provision of a Window or door sash that has a window or door sash profile; at least one Glasfalzeinlage inserted in a glass rebate according to the invention, wherein the Glasfalzeinlage is clamped between two opposite profile walls of the window or door leaf profile; a glass block placed on the glazing insert and a surface element accommodated in the glazing rebate, in particular an insulating glazing accommodated in the glazing rebate.

As used herein, the term "window or door" preferably refers to a wing of a plastic window or door. But there are also metal windows or metal doors, wooden windows or wooden doors and composite windows and composite doors into consideration. If it is the wing of a plastic window or a plastic door, as the main material of the sash profile of the invention window or door polyvinyl chloride (PVC), especially rigid PVC (PVC-U) or glass fiber reinforced PVC, the additional additives such. As stabilizers, plasticizers, pigments and the like are added, preferably. PVC can be well colored or dyed and hardly absorbs water.

With regard to the glazing rebate insert according to the invention, it may be preferable for the platen spring element to be designed as a spring tongue. Such a configuration of the support plate spring element as a spring tongue can be realized easily and offers a high spring action. Alternatively or additionally, it is particularly advantageous if the support plate spring element is formed with a three-sided undercut.

It is also helpful if the spring action of the platen-spring element is directed away from the platen, preferably directed substantially perpendicular to the platen.

According to the invention, it can also be used by users if the support plate spring elements of the glazing rebate insert according to the invention are formed from an elastically deformable, in particular elastomeric or thermoplastic-elastomeric material, preferably as knobs made of an elastically deformable material. When clamping the glass block between the invention Glasfalzeinlage and the surface element of the wing, the elastic limit of these materials is not exceeded, so that their spring action is fully retained. In addition, such elastically deformable materials have a higher coefficient of friction compared to the material of the glass block so that a higher stiction occurs between the glass fold insert according to the invention and the glass block. Thus, the probability of falling out of the invention Glasfalzeinlage from the respective wing can be further reduced. As elastically deformable materials of the spring element or the spring elements are thermoplastic elastomers, in particular thermoplastic elastomers based on PVC, PP / EPDM and TPS, SBS and ASA (acrylonitrile-styrene-acrylic ester terpolymer), and elastomers such as rubber or rubber preferred. The elastically deformable material of the spring element or the spring elements preferably has a Shore hardness in the range of 50 Shore A to 80 Shore A. Here are elastically deformable materials having a Shore A hardness (Shore A) in the range of 60 Shore A to 80 Shore A and in particular in the range of 65 Shore A to 75 Shore A preferred. A most preferred material has a hardness of about 70 Shore A (ranging from 68 Shore A to 72 Shore A). The specified values of the Shore hardness refer to the standards DIN 53505 and DIN 7868.

In preferred embodiments of the glazing rebate insert according to the invention, the elastically deformable material of at least one of the longitudinal wall spring elements has an indentation on its side facing away from the support plate. In this way, a "suction cup" effect between the elastically deformable material of the invention Glasfalzeinlage or inner wall of the airfoil. This additionally contributes to the fact that the glazing rebate insert according to the invention does not fall out of the sash profile.

Additionally or alternatively, it may also be advantageous if the glass fold insert according to the invention has at least partially a corrugated surface structure on its surface facing away from the glass fold. This prevents slipping of the glass block after placement on the Glasfalzeinlage invention.

With regard to the window or door leaf according to the invention, it may be preferred if the glass fold is bounded on one side by an inner wall of the window or door leaf profile, in particular by the inner wall of an outer flashover of the window or door leaf profile, and the inner wall of the window or door leaf profile Includes in the longitudinal direction extending retaining element which is in engagement with the elastically deformable material of the glass block bridge according to the invention. As a result, the holding element, the elastically deformable material of the glass block bridge directed to the mounting plate of the glass block bridge invention buckle of the elastically deformable Material cause and thus produce a positive connection, which in turn helps to reduce the risk of falling out of the glass block bridge from the sash profile significantly.

The glazing rebate insert and the window or door leaf according to the invention as well as individual parts thereof can also be produced line by line or layered using a line-building or layer-building manufacturing process (eg 3D printing), but preference is given to producing the window or door profile by means of extrusion as well as the production of the Glasfalzeinlage invention by injection molding.
