Window glass mounting arrangements

A window glass mounting arrangement, comprising

• a first channel-shaped part made of plastics material,
• a first reinforcing channel-shaped metal carrier embedded in the plastics material so as to embrace the channel formed by the channel-shape thereof,
• a second channel-shaped part made of rubber having walls and a base defining, running alongside the channel formed by its channel-shape, a longitudinal slot whose mouth faces in the same direction as the channel formed by its channel-shape, and
• a second reinforcing channel-shaped metal carrier embedded in the walls and base of the said slot so as to embrace the slot,
• the two parts being fitted together so that one side wall of the channel of the first part fits tightly into and is frictionally secured within the said slot of the second part, the two parts thereby together defining first and second channels running side-by-side and facing in opposite directions with the outside wall of the first channel being defined by the first part and the outside wall of the second channel being defined by the second part,
• the first channel being sized to fit over and grip a support member surrounding the window opening so that the second channel runs alongside the window opening for receiving the window glass,
• the outside wall of the second channel being completely free of any embedded and inseparable metal reinforcement but defining a groove, and including a removable stiffening member separate from but receivable in the groove so as to stiffen that wall and thereby to secure the window glass in the second channel.
