Description

VENTANILLA OF VENTILATION FOR MOTORIZED VEHICLES BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a vent window for motor vehicles, wherein the window pane or window to be opened is pivotable about a substantially vertical pivot axis that is disposed on the front. of the car, in the direction of travel. The ventilation window has a pivot connection with the adjacent pole or pole, which extends upwards, of the body of the carriage body. The hinge between the body and the glass of the window consists of at least one sheet or carrying arm, metal, which is connected to the car body post by at least one mounting screw.

Technical - Previous In the conventional ventilation windows for cars, the arm or metallic carrier sheet is folded a number of times and is directly fastened on the window glass with an adhesive. Attaching the metal carrier sheet directly on the window pane has the disadvantage of low elasticity. The metal carrier sheet or arm is sometimes removed from the window pane due to the pressure loads acting on the ventilation window. Because the metallic carrier sheet can be subjected to loading when the ventilation window is opened, the metal carrier sheet can deform in the area where it is attached by the adhesive to the window glass.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to overcome the disadvantages of the prior art and to provide a strong and more load resistant connection between the metal carrier sheet and the vent window.

Accordingly, the present invention provides an arm for a vent window wherein the metal foil section passing through the mounting screw is embedded in a drained and elastic composite, and the cast compound is secured on the window pane. with a layer of adhesive.

In the invention, the metallic carrier sheet is embedded in a drained, elastic composite, and in this way is secured to the window pane over an elongated area and thus within an elastic assembly. Therefore, the elastic connection of the metallic carrier sheet to the window glass is highly stable. Moreover, when the vent window is opened, any load that occurs will extend into the part of the metal carrier sheet that is embedded in the cast compound, without stressing the junction with the window glass. It has been found that the inherently elastic casting has the additional advantage that in the presence of tensioning load, a suction effect occurs towards the window pane between the latter and the casting, which additionally stabilizes the joint.

In a further embodiment of the invention, the metal carrier sheet is disposed in the drained composite so that it extends substantially parallel to the window pane. In this form, a relatively large area of the metal carrier sheet is advantageously embedded in the casting and, therefore, the entire structure requires only a small space on the window pane.

In another embodiment, the mounting screw is disposed through the metal carrier sheet, near one end of it, through a hole and in this area, the metal carrier sheet projects with a section of the metal sheet from the compound cast on the remote side of the window glass. This design saves space and is very simple.

In a preferred embodiment, polyurethane is preferably used as the cast compound.

BRIEF DESCRIPTION OF THE DRAWINGS Other objects and features of the present invention will become clearer from the following detailed description of the invention, taken into consideration with the accompanying drawings. It should be understood, however, that the drawings are designed solely as an illustration and not as a definition of the limits of the invention.

In the drawings, where similar reference characters indicate similar elements in all the various views: Figure 1 is a cross-sectional view of an assembly of the glass sheet of a ventilation window in accordance with the invention; Y Figure 2 is a cross-sectional view of the design of Figure 1, with the window glass pivoted outwards.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now in detail to the drawings and, in particular to Figure 1, there is shown a cast compound 4 which was applied to a portion of the window pane 3, the latter being arranged on the front surface in the direction of travel. A metallic carrier sheet 2 is embedded = n the cast compound, and at least one threaded mounting screw 1 is passed through and secured to the metal carrier sheet. The screw 1 is normally attached to an adjacent pole or strut, which extends upwards (not shown) of the carriage body. The drained composite 4 is attached to the window pane by an adhesive layer 5.

The metallic carrier sheet 2, as a whole, extends approximately parallel to the window glass and is bent several times in different places, at acute angles. A section 2a of the sheet metal of the carrier sheet projects out from the surface of the casting compound 4 onto the remote side of the window pane 3, and extends approximately parallel to the window pane. The section 2a of the sheet metal has a hole 8, such that the arrow Ib of the mounting screw 1 can be passed through the hole 8. The head of the screw is arranged on the side of the metal sheet , section 2a facing glass 3 of the window, projecting in this way and settling inside the empty composition without being joined there.

Figure 2 shows the window when the glass sheet 3 is in the pivoted out position. The window has been pivoted and spaced in the direction of the arrow 7. With this pivoting out, the section 6 of the metal carrier sheet 2 is preferably bent or slightly deformed, so that the screw 1 with its head is partially raised himself away from his seat on the drained compound 4.

As can be seen in Figures 1 and 2, the carrier sheet 2 has a central section 2a containing an opening 8 that is raised above its flat parallel portion (shown arranged on the emptied composite 4 with dotted lines). The raised center section 2a is attached at one end to the metal carrier sheet 2 in section 6, so that it can flex or pivot, as shown in Figure 2. The opposite ends of the metal carrier sheet 2 can be bifurcated from so that a part of each end is bent towards the upper surface of the drained composite 4 and a part is bent down towards the adhesive layer 5 (shown with dotted lines). This increases the surface area which is in contact with the compound 4 and thus is added to the strength and stability of the sheet 2 within the composite 4. The elastic casting compound is preferably polyurethane and the adhesive layer 5 can be any adhesive able to stick polyurethane to glass surfaces. Carrier sheet 2 is preferably chosen from a sheet metal similar to steel which is not brittle, but which can be die cut, molded into the cut and folded into the preferred shape, as well as flexible, as shown in Figure 2, without it being permanently deformed.

Accordingly, while only one embodiment has been shown and described, it is obvious that many changes and modifications can be made without departing from the spirit and scope of the invention.
