Vehicular door-hinge device with checker

Abstract

Provided is a vehicular door-hinge device with a checker, which comprises an inner cylinder (6) to be jointed to a female bracket (1), an outer cylinder (7) to be jointed to a female bracket (2), and a check force generating mechanism (20) interposed between the two cylinders (6 and 7). The mechanism (20) is constituted of a plurality of holding members (22) attached to the outer cylinder (7) and arrayed in the circumferential direction of the same, and a plurality of elastic members (23) for biasing those holding members (22) individually toward the inner cylinder (6). Each of the holding members (22) is equipped with a detent projection (26) for abutting against the outer circumference of the inner cylinder (6). The inner cylinder (6) is equipped, in its outer circumference, with a plurality of detent grooves (27), into and out of which the engagements of the detent projections (26) are made according to the relative rotations of the inner cylinder (6) and the outer cylinder (7). The pressure receiving areas of the holding members (22) for receiving the pressures from the elastic members (23) are set larger than the abutting areas of the detent projections (26) and the detent grooves (27). As a result, the vehicular door-hinge device does not lose the checking function, even if the check force generating mechanism is partially troubled, but is high in durability.

Description

technical field [0001] The present invention relates to a door hinge device for a vehicle that supports a door for opening and closing an entrance or a tailgate of a motor vehicle, etc., and particularly relates to an improvement of a locker type door hinge device for a vehicle as described below. A locker-type door hinge device for a vehicle includes: a first bracket fastened to one of the vehicle body or the door; a second bracket fastened to the other side of the vehicle body or the door; a hinge pin, It connects the two brackets so as to be able to rotate relative to each other; the inner cylinder is integrated with the first bracket and arranged coaxially with the hinge pin; the outer cylinder is engaged with the second bracket an integral body configured to surround the inner cylinder in a relatively rotatable manner with the inner cylinder; and a locking force generating mechanism disposed between the inner cylinder and the outer cylinder and generating a locking force ...

AI Technical Summary

Problems solved by technology

In such an existing locker-type door hinge device for vehicles, since one coil spring acts on a plurality of stop rollers at the same time, all stop rollers will not The lock function will disappear

And since the stop roller and the coil spring are always in a line contact state with high surface pressure, the stop roller and the coil spring are prone to wear
