Description

~093~jlO

Background of the Invention This invention concerns installing windscreens on motor vehicles, in a frame of a vehicle body that accommodates the screen, the frame having a support face parallel with the inside surface of the screen and an edge face surrounding the screen.
Windscreens are customarily held in place in motor vehicles either by embedding the margin of the screen in a groove of a peripheral rubber sealing strip and forcing the strip into a channel running around the windscreen opening of the vehicle body, or by bonding the screen directly to a frame portion of the body. Such a rubber strip can be stuck to the body as well as being held mechanically by the frame if desired;
the strip is usually so shaped as to bridge the peripheral gap between the screen and body so as to seal against the ingress of moisture. Such a strip may also present the finished assembly with a pleasing appearance, but, where there is a visible gap between the strip and the body, or, as is inevitably the case where the screen is bonded directly to the body, between the screen and the body, it is customary to provide a trim strip to bridge it. One recognized way of securing such a trim strip is by welding T-studs to the body at intervals around the frame, . - .
. .~

~a~3(;l0 assembling trim strips, which may be metal or plastics, on the studs, and then clipping a strip of channelled-shaped cross-section onto the clips.
Conventional ways of installing wlndscreens vary in complexity and cost and do not usually result in an assembly which can readily be dismantled for replacement of the screen if it is broken.
It is an object of the invention to provide an improved method of installing windscreens which, as economically as practicable from the point of view of cost, provides an adequately secured screen effectively sealed in the body frame of a car body, which is convenient to install with the dimensional variations of screens and frames currently tolerated in their manufacture and which permits ready replacement of the screen if necessary.
It is another object of the invention to provide an improved windscreen assembly in which the screen is adequately secured and readily replaceable.

~ .

'J3~;10 Summary of the Invention The foregoing objects are achieved in accordance with the invention by a method of installing a wirldscreen i~n a frame of a motor vehicle body, the frame providing a support face para:llel to the rear surface of the screen and an edge face at substantially 90 to the support face and 5 surrounding the periphery of the screen, headed studs projecting from the edge face at intervals around the frame, wherein a sealing strip of resilient material having a groove running along its length is placed round the screen with the margin of the screen accommodated in the groove of the strip, the screen and strip are placed in the frame, 10 and clips are assembled on the studs to hold the screen and strip in place, each clip having a base with a slot in it to engage under the stud head and a rib projecting from the base and bearing against the exposed surface of the strip to press the strip and screen firmly against the support face.
Preferably, the clips are molded of plastics material and are shaped to receive a channel-shaped trim strip which can be clipped onto them. The clips are preferably secured to headed studs provided on the dge face of the frame of the body, such studs conveniently being T-studs welded to the frame. The clips may thus have a base 20 with a slot for reception on the stud and, projecting at substantially 90 - from the base, a rib which bears against the sealing strip. Elongated fingers may project upwardly and curve outwardly from a top edge of the rib of each clip for reception in an inturned rim along an inner side of the strip. A flap projecting from the rib between the fingers may be , 1~3t~10 interposed between the trim strip and the screen to prevent squeaking when the body vibrates.
The slot in the base of a clip as referred to may, in a windscreen assembly in accordance with the invention, be inclined to the direction of the rib so that the rib is urged more closely towards the support 5 face of the frame the further it is pushed onto the stud in assembling of the windscreen.
The sealing strip may have a depending tongue to engage the edge face of the frame in addition to the support face, and the sealing strip may carry a pressure-sensitive adhesive to enhance the seal against 10 the frame. The groove of the sealing strip may have teeth running along it to facilitate gripping of the screen. The sealing strip may be shaped to leave the studs exposed for reception of the clips.
A windscreen assembly in accordance with the invention thus comprises a frame of L-shaped cross-section around an opening for 15 the windscreen, a windscreen with its margin embedded in a groove of a resilient sealing strip seated in the frame, headed studs located at intervals around the frame on an edge face surrounding the screen, and clips of L-shaped cross-section assembled on the studs and bearing on the exposed surface of the sealing strip to press the strip and screen 20 against a support face of the frame and thus hold the windscreen in place. Such a screen is adequately secured and effectively sealed but readily replaceable. Its installation is compatible with economy of cost and is able to accommodate the dimensional variations customarily tolerated in vehicle manufacture.

-1~)'33t;10 There now follows a detailed description, to be read with reference to the accompanying drawings, of a method of installing a windscreen in a frame of a motor vehicle body in accordance with the invention and illustrative thereof. It will be realized that this illustrative method, and the assembly which results from carrying S it out, have been selected for description of the invention by way of example and not of limitation of the invention.

~. .

1~'336il0 Brief Description of the Drawing An example of the invention is represented in the drawings, wherein:
Fig. 1 is a section through the device with a pane accommodated in a recess; and S Fig. 2 is a perspective view of the clip employed in the arrangement according to Fig. 1.

.

1~3g~10 Description of the Preferred Embodiment Fig. 1 shows the margin of a glass screen 10 which is embedded in a groove 12 of a flexible resilient sealing strip 14. On the walls of the groove 12 that are opposite to the flat sides of the screen there are longitudinal teeth 16 which exert locally relatively high pressure on the S surface of the screen, so that they grip the screen and make a good seal.
If so desired, the edge of the screen may be introduced into the groove 12 with an additional sealing agent.
The sealing strip 14, together with the screen 10, is accommodated in a recess which is formed by a sheet metal frame 17 of a vehicle body lO which is L-shaped in cross-section to provide a support face 18 parallel to the inner surface of the screen and an edge face 20 surrounding the periphery of the screen. In this recess the screen 10, together with the strip 14, can be freely inserted from the front (i . e . from the right viewing Fig. 1) . Thus, a wall 22 of the strip 14 is compressed 15 between the screen 10 and the support face 18. Thus a sealing zone 24 is effectively produced between the support face 18 and the wall 22.
If so desired the wall 22 in this zone can be provided with a pressure sensitive adhesive to ensure effective sealing.
The flexible sealing strip 14 is supported on the one hand against 20 the support face 18 and on the other hand against the edge face 20. In this way the screen 10, together with the strip 14, is given a defined position within the frame 17.
In order that the screen 10 in the position represented in Fig. 1 is secured against falling out of the frame, clips 30 are provided which 3~10 are formed in essence by a base 32 and an upstanding rib 34.
As can be seen from Fig. 2, the base 32 of the clip 30 is provided with a slot 36 which extends as far as the edge 35 of the base opposite the rib 34 (the slot being L-shaped in plan so that it opens into the edge 35) thus enabling the clip to be pushed onto a T-stud 38 with a head 39 of the stud bearing on a shoulder 40 of the base around the end and along the side of the slot, the shoulder providing ramps which force the base against the frame beneath the stud head.
To allow the clips 30, after the screen 10 together with the sealing strip 14 has been placed in position, to be assembled on these studs, the strip 14 is provided with a recess 42 (or "cut-away" portion) into which the base 32 of a clip can be pushed when assembling the clip on the stud. Such recess may appropriately run continuously lengthwise along the whole sealing strip so that the latter can be extruded as a rod of uniform cross-section. It is possible, however, to provide separate recesses locally only at the sites where the studs are located.
It is also possible merely to rely on the flexibility of the sealing strip and to push the clips into the flexible, yielding material of the strip without preformed "cut-away" portions; such a procedure could enable the strip to press additionally on the clips and further ensure their retention in their assembled positions.
As can be seen from Fig. 2, two elongated fingers 46 project upwardly and curve outwardly from an upper edge of the rib 34 of a clip 30 to engage an inturned rim along an inner side of a trim strip 48 of channel-shaped cross-section (see Fig. 1) . The trim strip 48 at 1(~33fi~D

its side remote from the fingers 46, locks over a shoulder 50 of the rib 34 and the trim strip is thus attached to give a pleasing appearance around the periphery of the windscreen. A flap 52 also projects from the rib 34 between the fingers 46 and becomes seated between the trim strip 48 and the screen 10, and hence prevents the trim strip from 5 scratching the screen or squeaking when the vehicle vibrateæ.
Whereas in the illustrative embodiment shown in Fig. 1 the wall 22 of the resilient sealing strip is pressed against the support face 18 of the frame by the pressure exerted by the clips 30 through the outer wall 26 of the strip, it will be realized that the clip, in an assembly 10 according to the invention, may be shaped to exert pressure directly onto the glass screen, or by causing a trim strip to press upon the screen, preferably with an intermediate flap. The arrangement shown in Fig. 1, however, with the rib 34 upstanding from the base 32 of the clip, the material of the clip and the cross-section of the junction between 15 the rib and base being such that the rib remains in fixed relationship to the base when the clip is assembled on the stud 38 and pushed onto the stud far enough to cause the rib to press strongly against the strip, the fingers 46, while bearing through the trim strip 48 and flap 52, being sufficiently resilient to retain the trim strip but not to exercise 20 a significant influence on the pressure exerted by the screen upon the - wall 22 of the sealing strip, is preferred.
In carrying out the illustrative method, the screen 10 with its surrounding sealing strip 14 is first placed behind the studs 38 so that the wall 22 of the sealing strip 14 lies against the support face 18.

1~3'~3(~10 l'hus, placing the windscreen in the frame is effected by compressing the sealing strip walls to enable it to squeeze past the studs. The clips 30 are then assembled on the studs and pushed as far as the operator can push them to bring the ends of the slots 36 close to the studs 38 and thus press the screen and sealing strip firmly 5 against the support face 18 of the frame. Finally, the trim strip 48 is assembled on the clips . Alternatively, some of the clips, for example those along one side of the frame (preferably the top or bottom) may be assembled on the studs first, and then one side of the screen, with its surrounding sealing strip placed behind clips, the remainder 10 being assembled on the studs after positioning the screen against the support face 18; in such a procedure, the first row of clips would be merely lodged under the stud heads, and tightened up by pushing them along the studs after positioning the screen. The procedure may be carried out in reverse order if the windscreen has to be reversed 5 for a replacement.
The illustrative method enables a windscreen to be assembled on a car body securely and in a manner to provide an effective seal against the frame, which is compatible with the dimensional variations of screens and frames currently tolerated in the manufacture of motor 20 vehicles and which permits ready replacement of the screen if necessary.
The method is economical from the point of view of cost, both in material and labor.
