Patent ID: 8726574

Claim:
A drawing device for imparting a biasing force in one direction to an opening and closing body movable relative to a frame when the opening and closing body moves in the one direction, comprising: a trigger pin attached to one of the frame and the opening and closing body; and a drawing device main body attached to the other of the frame and the opening and closing body, provided for catching the trigger pin to impart to the opening and closing body the biasing force in the one direction, the drawing device main body comprising: a base, a slider with a trigger catcher capable of catching the trigger pin wherein the slider is slidable relative to the base in a longitudinal direction after the trigger catcher has caught the trigger pin, an elastic member, disposed between the base and the slider, which imparts the biasing force so as to move the slider relative to the base in the longitudinal direction, and a damper mechanism which generates a damping force when the slider is biased relative to the base in the longitudinal direction by the elastic member, the damper mechanism comprising: a linear damper with a rod extendable relative to a damper main body, a rotary damper with a rotation axis rotatable relative to the damper main body, and a damper base provided in the base and slidable in a longitudinal direction, to which one of the rod and the damper main body of the linear damper is mounted, and to which one of a rack engaged with a pinion of the rotation axis of the rotary damper and the damper main body of the rotary damper is mounted, wherein the other of the damper main body and the rod of the linear damper is mounted to the slider, and the other of the damper main body of the rotary damper and the rack engaged with the pinion of the rotation axis is mounted to the base, and wherein, when the slider moves relative to the base in the longitudinal direction by the biasing force of the elastic member, first the damper base moves relative to the slider causing the rod of the linear damper to contract so that the linear damper causes a first damping force, then the base moves relative to the damper base and the slider, and the pinion of the rotary damper rotates to cause a second damping force.
