Abstract
In a door-locking device, an output lever is connected to a release member and other operating mechanisms in order to eliminate a locking lever and a locking link. The elimination of these members decreases the number of connecting portions between members or mechanisms, thereby decreasing loose fittings therebetween. Thus, the generation of noise is lowered resulting in the realization of quietude. Also, the sense of operation of the door-locking device is more comfortable due to the decreased feeling of looseness.
Claims3
A door-locking device comprising:
- a main body accommodating therein a mechanism for opening and closing a door, said mechanism including a pawl member rotatably mounted on a pawl pin;
- a base mounted on the main body;
- a lift-lever rotatably mounted on the base for operating the opening and closing mechanism;
- an outer-lever rotatably mounted on the pawl pin;
- for at times transmitting rotation to the lift lever;
- a release member movably mounted on the outer-lever, said release member being engageable and disengageable with the lift lever for enabling and interrupting, respectively, the transmission of rotation of the outer-lever to the lift lever;
- and
- an output lever rotatably mounted on an axis extending substantially perpendicular to the axis of the pawl pin;
- said output lever having a holding portion at an end thereof extending substantially perpendicular to the axis of the paw pin connected to the release member for moving the release member into and out of engagement with the lift lever to enable and interrupt, respectively, the transmission of rotation by said outer-lever.
