1499866 Spring hinges SOC ANON AUTOMOBILES CITROEN 2 May 1975 [10 May 1974] 18574/75 Heading E2 A hinge comprises a base 9 for attachment to a fixed member 6 and a movable portion 7 for attachment to a movable member 2 and pivoted on a shaft 8 borne by the base. A resilient connection E, J urges the movable portion towards the adjacent closed or open position. The connection E, J comprises a transversely flexible rod 14 supported in bearings 15a, 15b on the base 9, a link 16 pivoted on the rod 14 and at the other end on a pivot 17 borne on an extension 13 of the portion 7. The distance l + d is greater than the distance e so that movement of the portion 7 from the open and closed positions bends the rod 14 which creates an opposing force until the pivot 18 passes through the plane through the rod 14 and shaft; thereafter the rod 14 assists opening or closing The arangement may be such that in the closed position the rod 14 provides a closing force. |
