Title:
DOOR OPENING AND CLOSING DEVICE
Document Type and Number:
Japanese Patent JPH0650045
Kind Code:
A
Abstract:

PURPOSE: To improve operation efficiency by causing a passive lever to move linearly for turning a latch member and reducing the loss of torque transmitted from the passive lever to the latch member at an engagement position.

CONSTITUTION: An active lever 41 and a passive lever 42 are made to perform horizontal linear motion, guided by the horizontal sections 41aa, 42aa and the slope sections 41ab and 42ab of respective slits 41a and 41b. Consequently, the engagement section 42d of the lever 42 performs linear motion, while travelling along the rotational locus of the lever 27. Also, while the lever 27 is being dragged by the engagement section 42d, dislocation at the coupled section thereof is limited to unidirectional turning, because the section 42d is performing linear motion. According to this construction, the loss of torque from the engagement section 42d to the latch lever 27 is reduced, thereby improving torque transmission efficiency.
