DE3522811A1 - Window guide for retracting windows, in particular of cars - Google Patents

Abstract

The invention relates to a window guide for retracting windows, in particular of motor vehicles, which are integrated into a vehicle body such that they are flush with the outer surface, there being bonded on each retractable window along an inside window edge in the lowering direction a fastening leg of an angular, rigid-angled, preferably U-shaped guide rail, the guide leg of which engages positively into a counterpart holding rail of a window frame covered towards the outside by the window. The window guide according to the invention is distinguished in that the bonded-on wall of the fastening leg comprises a rubber-elastic material, and in that the supporting, angle-reinforcing structure of the guide rail is formed by an expanded metal which compensates for expansions and is intimately connected to the bonded-on wall of the fastening leg.

Description

The invention relates to a disk guide for retractable windows, especially of motor vehicles, the specified in the preamble of claim 1.

Such a disc guide is already in DE-OS 31 24 628 discloses, the U-shaped guide rail is glued directly onto the relevant pane. Becomes here is a metallic one common for guide rails Rail used, so is the connection technology of the Gluing extremely problematic.

This problem arises from the different connect physical properties of each other the materials, for example with regard to their thermal expansion, their thermal conductivity and their Differentiate elastic behavior.

When gluing stationary windows into an assigned one Disc frames are therefore half thick strands of adhesive Weighing is based on polyurethane, which is capable of are an elastic balance between the disc and Frame.  

However, these strands of adhesive require long setting times and during the setting time the disc is fixed in position to the frame so that this adhesive technique for the present Use case is not suitable.

An elastic balance between the disc and the guide However, the rail is the same as for quick-setting adhesives necessary thin adhesive joints not reliably possible.

The invention is therefore based on the object Preamble of claim 1 corresponding discs further guide for retractable panes wrap that a metallic guide rail under ela static expansion compensation by means of a quick setting the adhesive is to be glued to an assigned pane.

This object is achieved with those in claim 1 specified means.

From the claims 2 to 6 advantageous Ausge Events of the invention.

The following is an embodiment of the invention hand explained in more detail a drawing.

This shows in

Fig. 1 is a side view of a door-side motor vehicle section, in

Fig. 2 shows a section along the line II-II in

Fig. 1 on an enlarged scale, and in

Fig. 3 shows the guide rail of FIG. 2 as a detail.

A door-side section of a motor vehicle 1 has two side doors 2 and 3 with associated side windows 4 and 5 , which can be lowered into the side doors 2 and 3 in a generally known manner.

The side windows 4 and 5 close to each other as well as to the adjacent body areas, the side windows 4 and 5 holding window frames 2 a and 3 a are covered to the outside by the side windows 4 and 5 respectively. To guide the side windows 4 and 5 in the lowering direction in the area of a body-side center pillar 6 , a mounting leg 7 a of a U-shaped guide rail 7 is glued to the inside of the associated side windows 4 and 5 , and a projecting guide leg 7 b of the guide rail 7 engages in a form-fitting manner in a groove of a receiving rail 8 arranged on the pane frame side, which is preferably integrally formed on the pane frame 2 a or 3 a . To tension between the biased in a conventional manner by a heat treatment for side windows 4 and 5 and to avoid the parent to each guide rail 7, the rail 7 Füh approximately rubber mainly of plastic for example, works or the like resin. In order to achieve the required functional stability, particularly with regard to the angular rigidity, the guide rail 7 is reinforced from plastic with a metal frame, which is referred to as expanded metal 9 . The expanded metal 9 designed as a profile bar is embedded in the fastening leg 7 a and in the base of the guide rail 7 and is led out in the transition region to the guide leg 7 b , the plastic part of the guide leg 7 b being enclosed on the outside by the expanded metal 9 .

In order to compensate for the expansion between the side windows 4 and 5 and the respectively assigned guide rail 7 , the expanded metal 9 in the embedded section is weakened in cross-section by means of numerous recesses 10 . These recesses 10 can have, for example, a diamond shape or can also be replaced by transverse incisions. Essential in the design or measurement of the cross-sectional weakening is the possibility of expansion compensation between the closed-walled, embedding section of expanded metal 9 and the pane-side connection area.

Since the guide rail 7 is thus encompassed in the region of the guide leg 7 b on the outside by the closed-walled section of the expanded metal 9 , the guide leg 7 b can run directly in the receiving rail 8 , where the groove of the receiving rail 8 is provided with a noise-reducing coating 11 should be. Teflon, synthetic fiber felt or the like is suitable as the coating material. This can save an otherwise neces sary additional slide rail.

Alternatively, it is provided that the expanded metal 9 is constantly made of a wire mesh and is also embedded in the region of the guide leg 7 b in the rubber-elastic plastic. In this case, however, an additional slide rail must be provided on the track side. While the expanded metal 9 designed as a profile rod should consist of stainless steel for reasons of increased risk of corrosion, the completely embedded wire mesh, on the other hand, can be made of inexpensive steel wire.
