Claims

[Scope of utility model registration request]

A fixed side member 4 is fixed to a fixed frame 5 and has a pair of upper and lower connecting portions 2゜3 projecting therefrom;
a rotating side member 8 having a pair of upper and lower connecting portions 6 and 7 protrudingly located inside the connecting portion 3; a joint 11 that is fitted onto the lower surface of the connecting portion 6 and has a plurality of claws 10 on the outer peripheral edge surface 9; The joint 14 has a plurality of pawls 12 on the outer peripheral surface 13 that engage with the pawls 10, and the engaging protrusion 37 at the lower end is inserted into the receiving groove 38 on the upper surface of the connecting portion 3 through the through hole 26 of the connecting portion 7, and the upper end portion 17 is fitted. Connecting part 7
The clutch body 16 protrudes from the upper surface, the inclined cam portion 18 provided on the lower surface of the clutch body upper end portion 17, the locking groove portion 19 provided on the upper surface of the clutch body upper end portion 17, and the base of the upper surface of the connecting portion 7. The inclined cam part 20 provided on the front side of the rotating side member 8, the retaining protrusion 21 provided on the front side of the rotating side member 8, and the notch part 2 of the joint 14 at one end.
2, and the other end is inserted into the notch 23 of the upper end 7 of the clutch body.
A coil spring 15 for urging rotation of the rotating side member 8 inserted into the
and the through hole 27 of the connecting part 6, the through hole 42 of the joint 11, and the joint 1.
4, a through hole 44 of the clutch body 16, and a pivot shaft 28 which is fitted into the through hole 44 of the clutch body 16 and the coil spring 15, and which is fitted and fixed into the through hole 24 of the connecting part 2 and the through hole 25 of the connecting part 3. When releasing, the inclined cam part 18 is pushed up by the inclined cam part 20, the engaging protrusion 37 of the clutch body 16 is removed from the receiving groove 38, and the rotational force to the rotating member 8 is cut off. This automatic hinge adjusts the rotational biasing force of a spring 15 by changing the engagement position of the claw 10 of the joint 11 and the claw 12 of the joint 14.
