NZ787938B2 - Improvements in or relating to window stays - Google Patents

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). The frame plate has a forward part (6) that is angled in an outboard direction towards an outboard side of the frame plate so that a front edge (2a) of the frame plate engages a rearwardly facing edge (101) or surface of the window frame once installed. The frame plate as configured assists with installation stability and ease of alignment with a window frame.

Claims (20)

Claims:

1. A window stay comprising a frame plate and a sash plate connected by one or more linkages, wherein the frame plate has a forward part that is angled in an outboard direction towards an outboard side of the frame plate so that a front edge of the frame plate engages a rearwardly facing edge or surface of the window frame once installed.

2. The window stay as claimed in claim 1, wherein the forward part of the frame plate is configured to elastically deflect inwards during installation and spring back to an un-deflected position to engage the rearwardly facing edge or surface of the window frame once installed.

3. The window stay as claimed in claim 1 or 2, wherein the frame plate is configured so that once installed with the window frame the frame plate is captured in a front and back direction between the rearward-facing edge or surface of the window frame and a forward- facing edge or surface of the window frame.

4. The window stay as claimed in any one of claims 1 to 3, wherein the frame plate comprises a flange extending at or adjacent a rear edge of the frame plate in an inboard direction to engage the forward-facing surface of the window frame.

5. The window stay as claimed in any one of claims 1 to 4, wherein the front edge of the frame plate comprises a channel or groove to receive the rearwardly facing edge or surface of the window frame, so that, once captured in the groove the rearwardly facing edge or surface of the window frame holds the forward portion of the frame plate in an outboard and inboard direction of the window frame.

6. The window stay as claimed in any one of claims 1 to 5, further comprising one or more clips provided with the window stay, wherein the one or more clips are configured to engage features of the window frame to secure the frame plate to the window frame without penetrating the window frame.

7. The window stay as claimed in claim 6, wherein the clip is configured to extend through an aperture in the frame plate to engage an outboard facing surface or edge of the window frame.

8. The window stay as claimed in claim 7, 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 received through an aperture in the frame plate to engage an outboard facing side of the window frame.

9. The window stay as claimed in any one of claims 6 to 8, 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.

10. The window stay as claimed in any one of claims 6 to 9, 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.

11. The window stay as claimed in any one of claims 6 to 10, wherein the clip is elastically deformed to provide a force in an outboard direction to hold the frame plate against the window frame.

12. A sash and window frame assembly, comprising a sash attached to a window frame by a stay as claimed in claim 1.

13. The assembly as claimed in claim 12, wherein the frame plate is captured in a front and back direction between the rearward-facing edge or surface of the window frame and a forward-facing edge or surface of the window frame.

14. The assembly as claimed in claim 13, wherein the front edge of the frame plate comprises a channel or groove and the rearwardly facing edge or surface of the window frame received in the channel or groove to hold the forward portion of the frame plate in an outboard and inboard direction of the window frame.

15. The assembly as claimed in claim 13 or 14, wherein the window frame comprises a lateral flange presenting the forward-facing surface or edge.

16. The assembly as claimed in any one of claims 12 to 15, wherein the window frame comprises a recess or channel and a lip adjacent an opening of the channel presenting the rearwardly facing edge or surface of the window frame.

17. The assembly as claimed in any one of claims 12 to 16, further comprising one or more clips, wherein the stay is attached to the window frame by the one or more clips engaging features of the window frame to secure the frame plate to the window frame without penetrating the window frame.

18. A method for installing a sash in a window frame, comprising: providing the sash with window stays as claimed in claim 1 attached, configuring each stay in an open position, presenting the sash to the window frame, inserting the frame plate of each stay into the window frame so that the forward part of the frame plate of each window stay is deflected inwards before springing back to an un- deflected position so that the front edge of the frame plate engages a rearwardly facing edge or surface of the window frame.

19. The method as claimed in claim 18, wherein the method comprises engaging the front edge of the frame plate with the rearward facing edge or surface of the window frame, to capture the frame plate in a forward to backward direction of the window frame between a forwardly facing surface of a lateral flange of the window frame and the rearward facing edge or surface of the window frame.

20. The method as claimed in claim 18 or 19, wherein the method comprises 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.
