<p>931,066. Door latches. GENERAL MOTORS Ltd. May 7, 1962 [May 19, 1961], No. 18263/61. Class 44. A door latch e.g. for a motor vehicle comprises a frame having plates 4, 5, a toothed rotatable bolt 6 pivoted at 7 to the plate 4; a detent lever 19 pivoted at 20 to the plate 4 and bearing arms 22, 23, 24; and an actuating lever 33 pivoted at 34 to the plate 5. Arm 22 engages with the bolt 6 in the locked position, arm 23 is provided with a thrust surface 26 engageable by a push button rod 31, while arm 24 projects through an aperture in the plate 5. The actuating lever is movable in one direction so that its arm 38 contacts the arm 24 to rotate the detent lever 19 in a bolt-freeing direction, and is moved in the other direction to effect locking by covering the surface 26 of the arm 23 so as to interposition it between the push-button rod and the surface 26 and thus block the thrust movement of the rod. The actuating lever is rotated into the locking position either by means of an inside door handle 39A which is linked through levers 41, 44 and a slot and pin connection 47, 48 to the lever 33; or alternatively by rotation of the rod 31 of the push button by key means causing a plate 30A to abut a flange 33A of the lever 33. In a modification, Figs. 6 and 7 (not shown), the plate 30A and flanged lever 33 are replaced by a pin which is engageable with one or the other of two recessed edges of the lever 33.</p> |
