Operating mechanism of movable member, and automobile storage apparatus
First Claim
1. Operation mechanism for attaching a movable member to a main body rotatably between a first position and a second position, and holding the movable member in the first position by locking means, comprising:
- a base attached to the main body,a contact portion attached to the movable member,a coil spring having a winding portion with one end and the other end, said one end being fixed to the base and the other end being attached to the contact portion, said the other end being rotatable relative to the winding portion and rotating the movable member in the first position toward the second position, anda transfer track formed at the base and engaging the contact portion, said transfer track and said the other end of the coil spring being arranged to move the contact portion such that the movable member in the first position is moved to a predetermined position by said the other end by a force accumulated on the spring, and after the movable member passes the predetermined position in a direction to the second position, the winding portion of the coil spring again stores a force from the predetermined position to the second position by said the other end to reduce a movement speed from the first position to the predetermined position.

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.

8. A storage apparatus comprising:
-
a main body having an opening, a lid member for closing the opening of the main body, an operation mechanism for attaching the movable member to the main body rotatably between a first position and a second position, and a locking device for holding the movable member in the first position relative to the main body, wherein said operation mechanism comprises; a base formed at the main body and having an arc shape through-bore, a contact portion attached to the movable member, and including a shaft and a rolling member provided around the shaft, said shaft passing through the arc shape through-bore so as to move therealong, a torsion spring for applying a rotational force to the contact portion so as to move the contact portion along the arc shape through-bore, said torsion spring having a winding portion with one end and the other end, said one end being attached to the base and the other end being attached to the shaft, said the other end being rotatable relative to the winding portion and rotating the movable member in the first position toward the second position, and a transfer track for the contact portion formed at the base, said transfer track having an arc shape guide portion with a center of curvature same as that of the arc shape through-bore so that the shaft and the rolling member rotatingly travel along the arc shape through-bore and arc shape guide portion, respectively, by the rotational force of the torsion spring, wherein said arc shape through-bore includes a first end for placing the shaft when the movable member is in the first position, a second end for placing the shaft when the movable member is in the second position, and a middle position located between the first and second ends, said middle position being located in a horizontal direction furthest away from the center of the curvature, and said arc shape through-bore is arranged such that the shaft is moved from the first end to the middle position by said the other end by a force accumulated in the torsion spring and a force is again stored to the torsion spring when the shaft is moved from the middle position to the second end by said the other end to reduce a movement speed from the first position to the middle position. - View Dependent Claims (9, 10, 12)
