Abstract:
An operation mechanism attaches a movable member to a main body to be rotatable between a first position and a second position. The movable member is held in the first position by a locking device. The operation mechanism includes a base attached to the main body, a contact portion attached to the movable member, and a coil spring having one end fixed to the base, and the other end attached to the contact portion for urging the movable member in the first position toward the second position. A transfer track for the contact portion is formed at the base. By the transfer track, after the movable member in the first position is moved to a predetermined position by a force accumulated on the spring, when the movable member is pushed to the second position, the spring stores a force from the predetermined position to the second position.
Abstract:
A door operating mechanism is provided for rotatably switching a door relative to a base between a closed position and an open position. A sector gear is disposed in a support arm projected from the door. A rotary gear is disposed substantially in the center of the arc of the sector gear. A first gear of the base has internal teeth disposed to engage the sector gear. A second gear of the base is resiliently and displaceably disposed to engage the rotary gear. The door is rotatably disposed along a track corresponding to the first gear via engagements between the first gear and the sector gear, and engagements between the second gear and the rotary gear. A load received by the door in the closed position towards the bottom of the base is absorbed by resilient displacement of the second gear.
