Claim 2

A sealing and retaining arrangement for sealing and retaining a window glass in a window opening having a flange running therearound, comprising channel-shaped resilient metal support means embracing the flange, projection means integral with the support means and projecting outwardly of the window opening at least at intervals along the length of the flange, the projection means carrying locking means, a flexible channel-shaped strip structure comprising flexible material and sized in length to match the length of the periphery of the window opening and sized in cross-section to embrace the flange and the channel-shaped part of the said support means but not the projection means of the support means, a sealing part on the outside surface of the strip structure and positioned thereon to extend along the complete length of the flange and to be directed outwardly of the opening, and shaped to define a seat for receiving the peripheral edge of the window glass and the surface thereof on the inside of the window opening, a window glass in the opening and seated in and on the said seat of the sealing part of the strip structure, and a retaining member sized to extend around the said opening, the retaining member defining a first part which contacts the outside surface of the window glass in position on the opening, and a second part mechanically locking with the locking means on the projection means so as positively to hold the retaining member in position and thereby to hold the window glass in position.

Claim 3

An arrangement according to claim 1, in which the said support means comprises a plurality of clips mounted at intervals along the length of the flange, each clip defining a U-shaped part sized to embrace the flange and at least one arm projecting outwardly from the side of one leg of the U, the arms of the clips together forming the projection means.

Claim 4

An arrangement according to claim 2, in which each clip has a plurality of the projecting arms.

Claim 5

An arrangement according to claim 3, in which the arms of each clip are spaced apart from each other so as to define a mouth in which is received the said second part of the retaining member.

Claim 6

An arrangement according to claim 1, in which the locking means comprises interrupted surface formations on the projection means.

Claim 7

An arrangement according to claim 1, in which the retaining member is T-shaped in cross-section with part of the head of the T comprising the first part of the member and the leg of the T the second part.

Claim 8

An arrangement according to claim 6, in which the underside of the head of the T carries sealing means sealing against the outside of the window glass.

Claim 9

An arrangement according to claim 5, in which the retaining member comprises a member which is T-shaped in cross-section with part of the head of the T comprising the first part of the member and the leg of the T the second part, the leg of the T carrying interrupted surface formations which engage the interrupted surface formations on the projection means of the said clips.

Claim 10

An arrangement according to claim 1, in which the sealing part of the strip structure comprises two sealing lips running along the length of the strip structure and made of relatively soft flexible sealing material, one of them being positioned to engage the peripheral edge of the window glass and to define the said seat and the other to engage the surface thereof on the inside of the window opening.

Claim 11

A sealing and retaining arrangement for sealing and retaining a window glass in a window opening having a flange which runs around the opening and lies in the general plane of the opening, comprising a series of metal clips mounted at spaced apart intervals on the flange around the opening, each clip having a part of channel-shaped cross-section which embraces the flange and a plurality of arms projecting sideways from one outside surface of the channel-shaped part and outwardly of the said window opening and spaced at different distances from the mouth of the channel-shaped part with their facing surfaces defining locking profiles, a channel-shaped strip structure mounted on the flange and over the clips thereon and sized in length to match the periphery of the window opening and sized in cross-section to embrace the flange and the channel-shaped parts of the metal clips, the strip structure and the clips being sized and shaped so that the arms of the clips project clear of the strip structure, the strip structure incorporating a channel-shaped metal core covered in soft flexible polymeric material and defining two sealing lips of soft flexible material projecting from the outside surface of one wall of the channel of the strip structure so as to be directed outwardly of the said window opening, one said sealing lip being positioned adjacent the distal edge of that wall of the channel of the strip structure so as to define, with the outside surface of that wall, a seat for receiving a peripheral edge of the window glass, and the other said sealing lip being positioned adjacent the base of the channel of the strip structure and angled so as to press against the surface of the window glass inwardly of the peripheral edge thereof, and beading having a T-shaped cross-section and sized in length to match the periphery of the window opening, the leg of the T defining locking means and projecting between the projecting arms of each said clip with the locking means locking with the locking profiles on the said arms so as to hold the beading in position with at least part of the underside of the T of the beading resting against the window glass when seated in the window opening on the said seat provided by the first sealing lip of the channel-shaped strip structure, the beading providing substantially the sole means of securing the window glass in the opening.

Claim 12

A sealing and retaining arrangement for sealing and retaining a window glass in a window opening having a flange which runs around the opening and lies in the general plane of the opening, comprising a series of metal clips mounted at spaced apart intervals on the flange around the opening, each clip having a part of channel-shaped cross-section which embraces the flange and a plurality of arms projecting sideways from one outside surface of the channel-shaped part and outwardly of the said window opening and spaced at different distances from the mouth of the channel-shaped part with their facing surfaces defining locking profiles, a channel-shaped strip structure mounted on the flange and over the clips thereon and sized in length to match the periphery of the window opening and sized in cross-section to embrace the flange and the channel-shaped parts of the metal clips, the strip structure and the clips being sized and shaped so that the arms of the clips project clear of the strip structure, the strip structure incorporating a channel-shaped metal core covered in soft flexible polymeric material and defining two sealing lips of soft flexible material projecting from the outside surface of one wall of the channel of the strip structure so as to be directed outwardly of the said window opening, one said sealing lip being positioned adjacent the distal edge of that wall of the channel of the strip structure so as to define, with the outside surface of that wall, a seat for receiving a peripheral edge of the window glass, and the other said sealing lip being positioned adjacent the base of the channel of the strip structure and angled so as to press against the surface of the window glass inwardly of the peripheral edge thereof, and beading having a T-shaped cross-section and sized in length to match the periphery of the window opening, the leg of the T defining locking means and projecting between the projecting arms of each said clip with the locking means locking with the locking profiles on the said arms so as to hold the beading in position with at least part of the underside of the T of the beading resting against the window glass when seated in the window opening on the said seat provided by the first sealing lip of the channel-shaped strip structure, the beading providing substantially the sole means of securing the window glass in the opening.
