Description

Spring element to fix a sheet of glass.

The present invention relates to a bar support profile for a window frame and an element of glass fixing and a seal associated with said profile bar

In the field of building frames, such such as window frames, doors and the like, the use of Metal profile bars are spreading more and more.

In the case of a window, said bars of Metal profile are used to form a fixed frame and a frame mobile that supports a sheet of glass.

Conventional interior frames for windows are formed by means of a support profile bar and A glass retention profile bar that are fixed together. Between the profile bars and the glass are placed together tightness (see, for example, the document DE-A-4301395).

In some cases, the support profile bar it comprises an inner tubular part and an outer tubular part provided with a respective substantially parallel support fin on the sides of the glass The inner tubular part has a C-shaped seat in whose interior the bar is mounted glass retention profile. The retention profile bar of glass has a substantially shaped cross section a "U" and features a C-shaped seat that receives the sealing gasket coupled with the inner side of the glass. The support fin of the outer tubular part has another seat in the form of a C-channel that receives the sealing gasket attached with the outer side of the glass. The support fin of the part Inner tubular is coupled with the fixed frame.

In the frames made with these bars profile, the glass retention profile bar is arranged in the inside the glass and the support fin of the outer tubular part it also performs the function of covering it, so that the fin of support and glass retention profile bar feature practically the same width.

In other cases, the support profile bar comprises a tubular part and a substantially longitudinal longitudinal wall  parallel to one side of the glass and coupled to the tubular part. The Tubular part has a C-shaped seat that receives the sealing gasket coupled with the inner side of the glass. The tubular part is also provided with a support flap substantially parallel to the sides of the glass and coupled with the fixed frame The longitudinal wall has a longitudinal cavity inside which a retention profile bar is mounted glass having a substantially shaped cross section of "I" or "L". The glass retention profile bar protrudes laterally from the longitudinal wall towards the glass and supports another sealing gasket coupled with the outer side of the glass.

In the frames made with the latter profile bars, the glass retention profile bar is it has on the outside of the glass and, presenting a width practically equal to that of the tubular part of the profile bar of support, covers it.

In both cases, the presence of the bar glass retention profile increases the dimensions of the frames interiors of doors or window frames in the plane of the glass and free an opening for the glass, which presents small dimensions This opening adopts even dimensions smaller when a window with a metal frame is applied to a general wooden frame of a preexisting window. For the therefore, the glazed area of the windows made with these frames is limited and penalizes the level of lighting of the rooms.

The present invention relates to an element spring to attach a glass sheet to a profile bar formed by a folded plate in the form of "L" that has a first and second parts that are substantially perpendicular, being able to press said first part of said plate against said outer side of said glass and being able to introducing said glass and said second part of said plate in "L" shape in a longitudinal cavity of said bar of profile, characterized in that said second part of said plate in "L" shape is provided with inclined side fins forming an elastic support between said glass sheet and said profile bar

Preferably, said second part of said "L" shaped plate has at least one tongue that it can be introduced in a recess of said profile bar.

Advantageously, said first part of said "L" shaped plate is provided with a band of material elastic polymer that can make contact with said outer side of said glass.

Preferably, said first part of said "L" shaped plate features a hole designed for receive a tool to place said spring element in said glass sheet and inserting said second part in said longitudinal cavity and said tongue in said recess.

The fixing spring element of the present invention, thanks to its lateral elastic fins, It has a great capacity to deform and support elastically the glass sheet with respect to the profile bar of support. Thus, the spring elements present the advantage of allowing to admit and correct possible strikes and tolerances of the dimensions and the placement of the sheet glass.
