975,070. Hinges. ATWOOD VACUUM MACHINE CO. Feb. 26, 1962 [Sept. 22, 1961], No. 7373/62. Heading E2F. A hinge, particularly for an automobile door, comprises a generally U-shaped outer member 13 and an inner member 18 pivoted on a pintle 24 between the limbs 11, 12 of the U, at least one of the edges 16, 17 of the inner member being provided with a friction area, preferably in the form of a pad 14, which is in frictional engagement with the inner surface of the adjacent limb of the outer member through at least a portion of the range of movement of the hinge, the said surface being so shaped that the frictional resistance to the movement of the hinge in the said portion of the range varies with the relative angular positions of the two members. In Fig. 3 the limbs are formed with ramps 10 which increase the frictional resistance as the door approaches its open position, but various combinations and arrangements of ramps are illustrated whereby the resistance can be increased, decreased or maintained constant at various stages of the movement. The pads 14 are fitted in recesses 15 in the member 18, ribs 42 being formed in the base of each recess to anchor the pads permanently in place. A rubber bumper 40 (not shown) may be fitted on a cross-brace 28 of the outer member to arrest the inner member in the open position. Specification 758,330 is referred to. |
