<p>A hinge for a door or window 2 comprises a first pivot axis 14, a second pivot 15, which is parallel to and spaced from the first pivot axis 14, and a control member 22 extending from the door or window 2 to frame 1 to control rotation of the door or window 2 about the second axis 15 during rotation of the door or window about the first pivot axis 14. The control member 22 may include a telescopic arm 23 slidably received in a sleeve 25. Alternatively it may include a hook end 36 which co-operates with a protuberance 37 to bias the door or window 2 into a closed position. The control member 22 may also have a stay member 40 pivotally mounted thereon and received in an elongate guide channel 42 in the frame 1. The hinge may have an intermediate member 18 having an aperture 21 for receiving a strengthening element.</p> |
