Description

A method of manufacturing a window pane assembly and a window pane assembly

Technical field

The invention relates both to a method of manufacturing a window pane assembly comprising spraying and to a window pane assembly.

BACKGROUND OF THE INVENTION

DE 36 04 389 A1 discloses a window pane assembly comprising a frame arranged along the outer edge region of the window pane, said frame comprising a profile section which extends at least partially on the inner side and on the front side of the window pane edge area. This frame is made of an elastomeric material and forms a seal to seal the window pane in the opening into which it is inserted, the opening being provided in the body of the vehicle of which the parts are surrounded. A retaining element is attached to the frame by means of an adhesive. This retaining element is intended to secure the position of the pane adjacent to the vehicle body.

Further, US 4,841,698 A discloses a window pane assembly in which the outer edge region of the pane is surrounded by a frame that includes a profile section that extends on the inner, front and outer sides of the pane to surround the edge area of the pane. Separately from this profile section and at the same time in a position adjacent to this section there is provided a fastening element which is designed as an injection molding and which comprises a suction cup retaining section which is fixed on the inside of the pane by means of an adhesive applied to the suction cup. The fastening element comprises a retaining element by means of which the window pane can be attached to the vehicle body, the fixing element being arranged on the window pane separately from the injection molding.

Furthermore, DE 198 18 153 B3 discloses a window pane assembly which is intended to be inserted into a receiving opening provided in a vehicle body. In its outer edge region, the window pane assembly is provided with an injection molding, in which the insert part is arranged. The insert comprises a fastening section located in the spray mold, said fastening section being located separately from the window pane itself. Furthermore, the insert comprises a retaining element, which is intended, for example, to receive an orifice therein. The window pane is attached to the vehicle body by means of an adhesive strip applied thereto.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for manufacturing a window pane assembly as well as a window pane assembly itself, in which the insert parts are incorporated into the injection molding, making it possible to manufacture such a window pane assembly in a simple and inexpensive manner.

SUMMARY OF THE INVENTION

This object is solved by designing a method of manufacturing a window pane assembly comprising a window pane and a frame disposed along an outer edge area of the window pane, said frame being formed as a splash, wherein the method comprises prior to inserting the window pane into the spray application tool. the insert panel is placed on at least one of the window panes in the peripheral region of the pane, then fixed to the pane by pressing the self-suction foot and then sealingly sealing the injection molding tool and spraying the window to form a frame while encapsulating the self-suction foot. The arrangement in which the insert is provided with a self-sucking shoe allows the insert to be attached to the pane in its peripheral region on one or both sides and subsequently inserting the pane so equipped into the injection molding tool,

Whereby the position of the inset parts on the pane remains constant, even if the individual inserts are held on the underside of such a pane. This makes production fast and inexpensive, especially when using machines equipped with a rotary table.

In addition, the insert can be placed on the pane without using glue. This is associated with the advantage that there is no need to apply liquid adhesive or use adhesive tape. In addition, it is not necessary to apply the adhesive adequately to the inset parts or to the edge area of the pane. In addition, this avoids having to wait for the reaction time to elapse.

A further advantage is that the insert parts can be positioned on both sides of the edge region of the pane before being inserted into the injection molding tool. The requirements placed on the window pane assembly and the injection molding are gradually becoming more complex, which also entails the requirement for the two-sided arrangement of the insert parts instead of their former one-sided arrangement. This also allows the use of these inserts as fasteners, which may consist, for example, in that the inserts placed on one side of the pane are used to position the pane on the vehicle body while the inserts placed on the opposite side of the pane are used as a holding element for an embedded aperture or decorative strip.

A preferred method of spraying on the pane is to perform the process in a vertical injection molding machine. Using such a vertical injection molding machine, flattening of the window pane in the horizontal plane is possible. In this context, rotary tables which consist of two partial tables are preferably used. The first part table forms the loading and unloading site, while the second table is used to create splashes during the loading and unloading of the product performed on the first table. By attaching the inserts to the pane due to self-adhesion, the displaceable movement of one table from the loading and unloading position to the sprayable position can be performed without being associated with the possibility of deflecting one or more inserts from the correct position; with the risk of losing these insertion parts. Furthermore, it is possible to arrange the inserts on the underside of the pane without the risk of detaching the inserts from the pane after insertion into the tool, until spraying is performed.

The object of the invention is further solved by providing a window pane assembly in which the insert is provided with a self-suction shoe which, when placed on the window pane, adheres to the pane, at least one such self-suction shoe being encapsulated by spraying. Such window panes can be manufactured inexpensively, since no additional procedures are needed to secure the position of the insert on the window pan until spraying. A further advantage of such a window pane assembly is that after the spraying operation, the self-suction foot that is part of the insert is permanently held in a fixed position relative to the window pane to which it is attached.

According to a further preferred embodiment of the window pane assembly, the self-sucking foot of the insert part is designed as a suction cup, which is preferably provided with a circular suction flap. This makes it possible to obtain a quick adhesion of the shoe by pressing it against the pane.

In a preferred embodiment, the holding element of the insert part is formed as a hard component made of plastic or metal, on which a suction cup formed as a soft component made of plastic is then arranged. The plastic used to produce the hard component is in particular PP, ABS or ABS PC.

In particular, a thermoplastic elastomer may be used to form the suction cup.

The suction cup may preferably be formed as a two-component injection molding, the holding element being a hard component and the suction cup being a soft component.

-2GB 2018 - 20 A3

Alternatively, the insert may also be formed of two components, the suction cup being attached to the retaining element by means of a clamping fastener, such as a U-shaped notch.
