643,168. Hinges. SVARTVIKS AKTIEBOLAG. Aug. 1, 1947, No. 21035. Convention date, June 2. [Class 65(ii)] In a hinge adapted to mount a window on a horizontal axis and to provide a braking effect during at least a part of the opening movement thereof, a lever transmits a braking force derived from the weight of the window, the arrangement being such that said force is greater than the braking force which would occur if the window were supported directly by a braking surface. A window 2 carries a pin 15 pivotally supported by a sector plate 6 which is pivoted on a pin 5 fixed to the frame 1. In a partly open position of the window (as shown), a pin 19, fixed to the frame and projecting through a slot 21 in the plate 6, engages a lever 9 pivoted at 8 to the plate 6 and thus urges a brake surface 11 on the lever against an arcuate flange 12 fixed to the window concentrically to the pin 15. Further pivoting of the window about the pin 5 is thus braked. In a modification the pin 19 is carried by the lever and cooperates with a surface provided on the frame. |
