Abstract
To hold windshield glass in position on a vehicle, a sealing member is used which has two parallel side-by-side oppositely facing channels, one of which fits over a flange around the opening, and the other of which grips the periphery of the window glass. A stiff metal retaining member of generally channel-shape is removably fixed to the window surround as by means of threaded bolts or pins and wedges and holds the sealing member on the flange. Finally, a decorative beading covers and is fixed to the retaining member.

Description
Background of the Invention
The invention relates to windows and more particularly to arrangements for sealing and retaining glass (which term is used herein to include like transparent or translucent media) in window openings such as, for example, window openings in vehicle bodies, particularly windshield openings.
In fixing a window glass in an opening, it is necessary for the fixing arrangement to be simple and quick to use, to provide an effective weatherproof seal, and to provide secure retention of the window glass. These requirements are particularly important in fixing arrangements for fixing glass in a windshield opening in a motor vehicle body; and in that application it is especially important that the fixing arrangement provides secure retention of the glass so as to hold it in position even when struck forcibly by, for example, an occupant of the vehicle in the event of a crash. In fact, such a requirement is not only desirable but is required by official regulations.
However, it will be appreciated that any fixing arrangement, while securely retaining the glass in position, should also be such as to be easy to use so as both to minimise production costs and to ease replacement of the window glass in case of breakage. Furthermore, it should provide a proper weather seal and be pleasing in appearance.
A sealing and retaining arrangement for retaining glass in a windshield opening is known in which the glass is primarily held in position by means of a layer of adhesive between the glass and the flange around the opening. In addition, clips are placed at intervals around the opening and mounted on the flange, these clips having extensions directed both inwardly and outwardly of the window opening, and these extensions hold decorative moldings. In such an arrangement, the glass is primarily held in position by the adhesive, and use of adhesive complicates the fitting operation.
It is an object of the invention to provide an improved sealing and retaining arrangement for sealing and retaining a window glass in position in a window opening.
Brief Summary of the Invention
According to the invention, there is provided a sealing and retaining arrangement for sealing and retaining window glass in a window opening defined by a surround which supports a flange running around the opening, comprising flexible sealing means on or for mounting on the flange and providing a channel which is arranged for receiving an edge of the window glass and for running along the length of at least a portion of the flange, a stiff retaining member shaped to make contact with an external surface of the sealing means, and locking means for releasably locking the retaining member to the surround so that it retains the sealing means on the flange.

Description of Preferred Embodiments
As shown in FIGS. 1, 2 and 3 particularly, the vehicle body 10 has an opening 12 for receiving the windshield, the opening 12 being defined by surround 13 having a flange 14 (FIG. 2) which runs around the opening. For supporting and sealing the windshield 16 itself in the opening 12, there is provided a double-channel seal 18. The seal 18 may be made of rubber or plastics material and is arranged to define a first channel 20 by means of which the seal 18 clips onto and is supported by the flange 14, and a second channel 22 which is of greater cross-section and receives the window glass 16. The seal may incorporate lips 24 and 26 which run along the length of the channel 22 and respectively seal against the side and periphery of the window glass 16 for draught and weatherproofing purposes.
The seal 18 may, if desired, incorporate an embedded metal reinforcement (not shown).
In order to hold the seal 18 securely in position on the flange 14, retaining strips 30 are provided. As shown in FIG. 1, there may be four such strips 30, running respectively along the four sides of the opening 12 but being clear of the corners in the opening. Each retaining strip 30 is channel-shaped but the distal edge of one wall of the channel is extended outwards at 32 to provide a flange or lip 33 which makes contact with the outside wall of that part of the seal 18 defining the channel 22.
In order to hold the retaining strip 30 in position, a series of pins 34 (see FIG. 3) are riveted or welded or otherwise suitably fastened to the surround 13 so as to project at intervals around the periphery of the opening 12 as indicated in FIG. 1, the pins 34 being on the outside of the opening. The retaining strips 30 are provided with slots 36 at corresponding intervals (see FIG. 5) and when the strips 30 are placed in position, the pins 34 are accommodated in the slots. The pins 34 interact with wedges 38 to hold the strips 30 in position. The wedges are illustrated in FIG. 4. Each one has a wedge portion 39 and jaws 40.
In operation, the windscreen glass 16 is first fitted into the channel 22 of the seal 18, and the latter is then placed in position in the opening 12 by engaging its channel 20 with the flange 14. The strips 30 are then placed in position around the periphery of the opening 12 so that their slots 36 clear the pins 34 and so that their flanges of lips 33 make contact with the outside wall of the seal 18. The wedges 18 are then placed into the channel portions of the retaining strips 30 and slid laterally so as respectively to come behind the pins 34, that is, between the pins 34 and the base 42 of the retaining strip 30. In this way, the retaining strips 30 are securely held in position.
Finally, a decorative beading 44 (omitted from FIG. 1) is placed in position and held there by means of a tongue portion 48, which extends longitudinally along the beading and which engages the jaws 40 of each wedge 38.
In FIGS. 6, 7 and 8, parts corresponding to those in FIGS. 2 to 5 are similarly referenced. The arrangement of FIGS. 6, 7 and 8 differs from that of FIGS. 2 to 5 in that the wedges 38 of the latter Figures are replaced by retaining members 50 each of which has an untapered extension 52 and the jaws 40. In addition, each extension 52 has a through hole 54 and corresponding holes 56 are provided at intervals along the length of the base 42 of each retaining strip 30, see FIG. 8. Finally, the surround 13 of the vehicle is provided with holes 58 (FIG. 6) at intervals, each such hole being threaded so as to receive and retain a respective bolt 60. Each bolt 60 passes through the hole 54 in one of the retaining members 50 and the corresponding hole 56 in the base 42 of the retaining strip 30. Instead of bolts, other types of suitable fixtures can be used.
The constructions shown in FIGS. 2 to 8 are merely examples of methods by which the retaining strips 30 can be held in position.
In each case, however, the purpose of the retaining strips 30 is securely to hold the windscreen glass 16 in position so that it is retained in position even under conditions of very rapid acceleration or deceleration, enabling the vehicle to pass stringent safety regulations. At the same time, however, the arrangements are such that the windscreen can be easily and rapidly fitted in position at low cost and can also be easily removed in the event of a repair being necessary.
Although the arrangements disclosed have been described with reference to the fitting of windscreens, it will be appreciated that they can be modified for fitting other window glass.
