Abstract

(57) [Abstract] [Objective] To secure a large area for a moving bed in a limited volume of a frame, to reduce the weight, and to manufacture it at low cost. [Structure] Using a rope for power transmission, the method of synchronizing the raising and lowering of the moving floor is solved by passing the rope near the center of gravity of the weight, and the weight is set at an arbitrary position to increase the area of the moving floor.

Description

[Detailed description of the invention]

[0101]

[Industrial applications]

 The present invention relates to a mobile lifting mechanism in which a person or an object is placed on a moving floor on a stage and is quickly pushed up or down from below the stage onto the stage.

[0092]

[Prior art]

 When moving one end of the moving floor in a movable lifting mechanism by applying a force upward or downward manually, the chain and gears were used to synchronize the multi-end. Since the installation position is limited and its shape is limited, it is not easy to use in a small space under the stage, and to synchronize the gears, the precision of mechanical processing was required to attach the gears, and the cost was high.

[0093]

[Issues of the invention]

 It was difficult to place all of the mechanisms in a narrow and limited space below the stage floor, and the area of the moving floor was small relative to the frame volume.

In order to solve the above-mentioned problems, the present invention can be installed at a position away from the frame or at one corner of the frame, and can be manufactured at low cost.

[0056]

[Means for achieving the object]

 The rope stretched from the movable floor passes through the guide pulley, passes through the pulley provided on the center of gravity line of the upper part of the weight, and is fixed to the upper part of the frame.

[0086]

[Function and effect]

In the invention according to the first aspect, the pulley above the weight is provided at the position of the center of gravity, and a plurality of ropes pass through the pulley. When one end of the moving floor is raised or lowered, the force directly acts on the center of gravity of the weight. A similar force acts on the rope connected to the multi-end, and it can be synchronized with nature

In the invention according to the first aspect, the rope can be freely routed, the weight can be set at any position and in any shape, the area of the moving floor can be secured widely, and the narrow space under the stage can be used effectively. .

According to the first aspect of the present invention, since the weight can be installed at an arbitrary position outside the frame, the rope can be separated and divided, and the size can be reduced.
