Abstract

1,081,077. Hinges with stays; door operating appliance. L. W. MENZIMER. April 12, 1965 [April 21, 1964], No. 16401/64. Headings E2F and E2M. In a vehicle door check-strap of the kind which is attached at one end to the door and passes between friction pads on the door pillar, the overall thickness of an enlarged elongated section 23 is initially greater than the space between the friction pad assemblies 26 and the first opening operation of the door permanently deforms the said section 23 to give the required thickness for frictionally controlling the door. In one form, a hinge 11 is attached to the door pillar 15 and door 16 and the checking strap 19 is pivotally connected to the door and passes through a slot 20 in the door pillar hinge leaf 13, the end part of the checking strap 19 having the enlarged elongated section 23 which frictionally engages the friction pad and backing plate assemblies 26 when the door is opened. The checking strap 19 may be made of two strips of low carbon steel with outwardly bowed section at 23 and which are spot-welded or rivetted together in face-to-face alignment. Stops 21 define the fully open position of the door. Reference has been directed by the Comptroller to Specification 986,367.
