Since the damper 62 exerts a damping force due to the degeneracy of the piston rod 62a, the damper 62 damps the rotational force in the direction in which the hinged door D closes with respect to the rotating cylinder 41 via the upper link bar 61. Then, it is possible to brake.

[Operation of this lever stopper]
Subsequently, the operation of the lever stopper S will be described.
In the closed state, the hinged door D is housed in the door frame W. In this state, the urging spring 52 of the self-closing device 20 is extended so as to be in the longest state, and the braking unit 60 is not operating.

(1) Fully open from closed door When opening the open door D, grasp the door knob (not shown) and hold the end of the hinge 9 on the opposite side of the hinge 9 from the vertical axis. Rotate. As the hinged door D rotates, the slide arm 11 extends from the storage portion 13, and the stopper 11a of the slide arm 11 abuts on the abutting step portion 13e of the storage portion 13 to restrict movement, and the movement is restricted in the fully open state. The position is fixed (FIGS. 5 and 6).

As the hinged door D rotates and the slide arm 11 extends, the rotating cylinder 41 rotates (clockwise in FIG. 6), and the lower ring bar 51 and the upper ring bar 61 attached to the hollow cylinder 42 also follow.

(2) From the fully open state to the closed door state When closing the open door D, the door knob (not shown) is grasped and rotated in the direction opposite to that in the case of the open door. As the hinged door D rotates in the reverse direction, the slide arm 11 is gradually stored in the storage unit 13 (FIG. 7).

As the hinged door D rotates in the reverse direction and the slide arm 11 is housed in the storage portion 13, the rotating cylinder 41 rotates in the reverse direction (counterclockwise in FIG. 8), and the lower portion attached to the hollow cylinder 42. The ring bar 51 and the upper ring bar 61 also follow and operate. Along with this, the spring slider 53 moves in the direction of the rotating cylinder 41, the compressed state of the urging spring 52 is gradually released, and a rotational force is applied in the direction of the damper holder 65 via the spring slider 53 and the lower link bar 51. By doing so, the slide arm 11 is rotated. This rotational force acts as a propulsive force for the hinged door D to self-close. Further, the damper slider 63 moves in a direction away from the rotating cylinder 41, the piston rod 62a of the damper 62 contracts, and a damping force acts due to the operation of the damper 62, so that the rotating operation of the slide arm 11 is gentle. Will be done in.
Finally, the hinged door D fits in the door frame W, and the closing of the door is completed (FIGS. 9 and 10).
