Document Type and Number:
Japanese Patent JP3198963
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To lock a door during the opening or the shutting and to enable the door to forcedly pass through without controlling a stopper device by lowering resistance in the movement of one of both up and down directions when the door partially passes through the stopper device.
SOLUTION: Slots 17 and 18 horizontally provided to a stopper body 13 are freely inserted in pivots 15 and 16 fixing the stopper body 13 to the deep direction of an opening 3 and are mounted to a position with specific height of the opening 3 side corresponding to a projection 10 projected to the side of a door 6, an elastic urging device 20 for elastically urging the stopper body 13 to the center side of the opening 3 is provided, and a cone shaped locking section 23 having a steep slope 21 and a gentle slope 22 is formed in the side of the stopper body 13. In the case the door 6 is moved in one direction of both up and down direction, the projection 10 slidingly passes through the gentle slope 22 by lowering resistance, and in the case the door 6 is moved in the other direction of them, the projection 10 sets resistance force slidingly passing through the steep slope 21 in larger than free moving force of the door 6.
