A friction stay includes a track 10 for attachment to a window frame. The track 10 has a nose portion 14 with a curved inner surface which receives the nose portion 28 of a bar 24. Bar 24 is pivotally attached to the track 10, by a link 16 joined to the bar 24 at rivet 25 and to track 10 at rivet 17. The bar 24 is also attached to a slider 15, engaged in track 10, by a link 21 pivoted on rivets 22, 23. A brace 18 extends from link 16 to slider 15 and is attached by rivets 19, 20. Optionally an extra link 26 may be included. To provide additional strength, in accordance with this invention, a link 31 is provided, pivoted to link 16 at 32 and to a second slider 35 to 34. |
