HINGED GATE DOOR OPENED AND CLOSED BY TURNING, HAVING OBSTACLE AVOIDANCE FREE CASTER
Document Type and Number:
Japanese Patent JP3704327
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To support a gate door body of a hinged gate door from a lower section by installing casters with an excellent appearance by avoiding an obstacle even when the obstacle such as a slope, unevenness, partial projections due to a water meter is present on the ground surface, and to smoothly open and close the gate door body by turning.
SOLUTION: A caster supporting member 5 is installed integrally at an arbitrary place in the longitudinal direction by screwing 56 a mounting substrate 51 on the underside of the lower stile 4 of the gate door body together with a projection-forming plate 53, and a caster 7 is mounted on the caster supporting member 5. The radius of a rotation with a hinge can be changed because the caster 7 can be moved in the longitudinal direction of the lower stile 4, and the obstacle on the ground surface is avoided by drawing a rotary locus different from the front end of the gate door body and the gate door body can be supported from the lower section with the excellent appearance.
