Door opening/closing device

Abstract

Abstract PURPOSE:To open an aimed door at a wide angle while avoiding the door from interfering with adjacent doors, etc., by actuating a pair of upper and lower gear lines in association with the turning movement of the door, and putting a pair of upper and lower arms in synchronous turning movements, the arms each supporting the door. CONSTITUTION:A pair of upper and lower gear lines 8, 12 for associating the turning movement of each arm 6, 5 with that of a door 7 are disposed. When a turning movement control force is exerted in the direction in which the door 7 is opened, the force is transmitted to the upper end 71 (lower end 72) of the door 7 and an externally rotating gear 9(13) starts to rotate. As a result, an intermediate gear 11(15) meshing with the externally rotating gear 9(13) is driven and tends to rotate in the direction opposite to the turning movement (that of the arrow (w)). However, the intermediate gear 11(15) meshes also with a fixed guide gear member 10(14) and therefore does not rotate.
