It is a laterally swinging hinge, which can longitudinally turn back and forth at an angle of approximately 315 DEG , and which is to be mounted on an ordinary door or automobile door; the hinge can also have a laterally swinging angle of at least 5 DEG in either direction so as to eliminate the possible trouble and drawbacks caused by the conventional hinge upon installing two or more than two hinges on one door and upon the center line of the two hinges not being aligned exactly; in that case, the conventional hinges can suffer from a bad friction or cause the door to be bent or unable to be operated normally. The hinge mainly comprises a set of hinge butts (1,2), a center shaft (7) being inserted through the cylinder (3,4,5) of the hinge butts (1,2); the center shaft (7) is substantially a slender cylinder including a ball-shaped part (12) in the mid portion thereof, an upper rod (13) and a lower rod (8) for holding the two butts (1,2). There are two sets of steel ball assemblies (16,17) being mounted on the both ends of the ball-shaped part (12) so as to provide a rolling friction between the center shaft (7) and the butts (1,2). |
