Title: Hinge device for damp truck
Inventor: TANIDE NOBORU
IPC: B60P1/28
Filed: 1980-02-29
Abstract: PURPOSE:To prevent a drop-off of a tipping body from a vehicle frame by designing such that either one of male and female engaging fittings is capable of moving in the vertical directions by a determined stroke. CONSTITUTION:When the tipping body 2 descends, a small diameter part 14 passes from an introduction part 21 through a throttle part 20 and enters inside of an engaging hole part 19. The small diameter part 14 of an operating rod 16 of the male engaging fitting 5 which is biased resiliently by a resilient member 7 upward from a normal engaging position is displaced eccentrically upward with respect to the center of the hole part 19 of the female engaging fitting 6. As a result of this, when the operating rod 16 is operated in the axial direction, the male engaging fitting 5 is pressed down against the resiliently biasing force of the resilient member 7, so that a large diameter part 13 of the operating rod 16 comes into an engagement with the hole part 19 of the female engaging fitting 6, thereby interconnecting mutually between the male and female engaging fittings 5 and 6. Thus, the large diameter part 13 and engaging hole part 19 slides and in this while, the tipping body 2 tilts rotating around the shaft of the operating rod 16 to damp the load therein.

A macro limit pin 14 is placed in the position indicated by a solid-line in the wide end state and is placed in a position 14' indicated by a broken line in the telephoto end, and consequently, macro focusing is maximum in the wide end and is reduced toward the telephoto end. When the macro operation ring 2 is operated beyond the operation limit position, the zooming operation ring and the macro operation ring are interlocked with each other. Thus, macro focusing is possible when the zooming operation ring is set to any focal length.
