US 8,079,446 B2 · Operational mechanism for movable body

Abstract

The invention provides an operational mechanism for a movable body in which, after a movable body is in an opened state, the movable body can return to a closed position, including a movable body rotatably attached to a support and rotatable between an engaged position, a closed position, and an open position; a rotating member rotatably attached to the support, that rotates due to movement of the movable body to the engaged position; a biasing member, one end of which is attached to the movable body, and the other end of which is attached to the rotating member; and an operation member, which rotates the rotating member, changes the biasing position of the biasing member with respect to the center of rotation of the movable body, and generates in the biasing member a rotational force that moves the movable body to the closed position or the open position.

Dependent claims

An operational mechanism for a movable body, comprising:

a movable body, rotatably attached to a support, and rotatable to an engaged position, a closed position and an open position;
a rotating member, rotatably attached to the support, which rotates due to movement of the movable body to the engaged position;
a biasing member, one end of which is attached to the movable body, and the other end of which is attached to the rotating member;
and
an operation member, which rotates the rotating member, changes a biasing position of the biasing member with respect to a center of rotation of the movable body, and generates in the biasing member a rotational force that moves the movable body to the closed position or the open position,
wherein the biasing member stores the rotational force to move the movable body toward the open position in the event that the movable body is in the engaged position, and the biasing member stores the rotational force to move the movable body toward the closed position in the event that the movable body is in the open position.

3 more elements

An operational mechanism for a movable body, provided with a movable body that moves, with respect to a support, between a reference position and a projecting position, and from the reference position to a predetermined position opposite the projecting position, wherein,

due to pushing the movable body from the reference position to the predetermined position, a biasing force toward the projecting position of a biasing member is stored, and when the pushing is released, due to the biasing force of the biasing member, the movable body moves to the projecting position and subsequently returns to the reference position due to a biasing force of the biasing member toward the reference position.
