Abstract

Provided is a window stay (1) comprising a frame plate (2) and a sash plate (3) connected by one or more linkages (5a, 5b). One or more clips (20) engage features of a window frame (100) to secure the frame plate to the window frame without penetrating the window frame. The clip comprises a projection (25) extending in an outboard direction to extend through an aperture (21) in the frame plate and engage an upwardly facing surface (106) of the window frame to support a sash in a vertical direction. The window stay as configured with regard to the one or more clips avoid the use of fasteners that penetrate the window frame, thereby avoiding the requirement for sealant to seal screw holes through the window frame.

Claims

Claims:

1. A window stay comprising a frame plate and a sash plate connected by one or more linkages, and one or more clips to engage features of a window frame to secure the frame plate to the window frame without penetrating the window frame, wherein the clip comprises a projection extending in an outboard direction to extend through an aperture in the frame plate and engage an upwardly facing surface of the window frame to support a sash in a vertical direction.

2. The window stay as claimed in claim 1, wherein the clip engages an outboard facing surface or edge of the window frame.

3. The window stay as claimed in claim 1 or 2, wherein the clip comprises a main portion that bears against an inboard side of the frame plate, and a leg that extends from a front end of the main portion, the leg configured to engage an outboard facing side of the window frame.

4. The window stay as claimed in any one of claims 1 to 3, wherein a front portion and a rear portion of the clip each engage an outboard facing surface or edge of the window frame to secure the frame plate to the window frame.

5. The window stay as claimed in any one of claims 1 to 4, wherein a rear portion of the clip engages an outboard facing surface of the window frame on an inboard side of the frame plate.

6. The window stay as claimed in any one of claims 1 to 5, wherein the clip comprises a flange extending at or adjacent a rear end of the clip in an inboard direction to engage an outboard facing surface of the window frame.

7. The window stay as claimed in any one of claims 1 to 6, wherein the clip is elastically deformed to provide a force in an outboard direction to hold the frame plate against the window frame.

8. The window stay as claimed in any one of claims 1 to 7, wherein the frame plate comprises a flange extending at or adjacent a rear edge of the frame plate in an inboard direction, and a notch or cut out through the flange to allow the clip to extend through the flange and engage a forward facing surface of the window frame.

9. A sash and window frame assembly, comprising a sash attached to a window frame by a stay as claimed in any one claims 1 to 8, wherein the window frame comprises a lip and a notch through the lip provides the upwardly facing surface.

10. The assembly as claimed in claim 9, wherein the window frame comprises a recess, channel or lip, and the clip extends through an aperture in the frame plate to engage the recess, channel or lip.

11. The assembly as claimed in claim 9 or 10, wherein the window frame presents a rearward-facing edge or surface and a forward-facing edge or surface, and the clip is captured between the rearward-facing and forward-facing edges or surfaces.

12. A method for installing an awning sash in a window frame, comprising: providing the sash with window stays attached, configuring each stay in an open position, presenting the sash to the window frame, inserting a frame plate of each stay into the window frame, providing one or more clips and engaging the one or more clips with features of the window frame to secure the frame plate to the window frame, including by inserting a lateral projection of the clip through an aperture in the frame plate to engage an upward facing surface of the window frame to support the weight of the sash.
