  • Publication number: 20050284742
    Abstract: When an operator applies a removing force to turn a switch portion b in a direction C2, a projection a4 abuts against a slope b71 so that the removing force as a reaction is applied to the slope. The removing force is divided into a component working along the slope b71 and a component F working in a same direction as a center axis X. Thus, the removing force is converted into a force F in the same direction as the center axis X. By means of the force F in the same direction as the center axis X, a pushbutton support b6 is moved downward as accordingly moving a movable contacts b9 away from a fixed contacts b12 via a contact axis b5.

  • Publication number: 20040206580
    Abstract: An elevator in which a dimension of an elevator shaft does not need to be increased when enlarging a hoist, and a position where a cage is suspended by a hoist cable can be flexibly selected. In an elevator according to the present invention, a hoist 10 is disposed such that a rotational axis thereof is vertically extended. Thus, when an axial dimension of the hoist 10 is increased to enlarge the hoist 10, a dimension of an elevator shaft does not need to be increased. Since a driving shaft 10a of the hoist 10 is vertically extended, an area occupied by the hoist is remarkably reduced when viewed in a horizontal cross-sectional view of the elevator shaft. Thus, the freedom to dispose the hoist 10 is enhanced so that a position where a cage 3 is suspended by a hoist cable 14 can be flexibly selected.
