Claims (1)

[Scope of utility model registration request] A support structure for moving a heavy object, which has a lower end space open toward the installation surface and has a structure that allows a human hand to reach the space from above, wherein the support structure has a structure in which a person can reach the space from above, wherein A frame with an open upper and lower surface that can be stored and installed in the frame, and an arm device and a lever device installed in the frame,
The arm device includes two arms whose proximal ends are pivotally supported by one end and the other end inside the frame, respectively, so that they can be rotated in the vertical direction, and whose distal ends extend in opposite directions, and each arm. and a moving member attached to the lower surface of the proximal end of the lever device, the lever device being pivotally supported inside the frame substantially above the distal end of one of the arms and moving in a direction along the arm. a lever that is rotatable; and a rotor that is pivotally supported inside the frame substantially above the tip of the other arm and that is rotatable in a direction along the arm and in contact with the other arm. , a connecting member whose ends are pivotally connected to the lever and the rotor at a position apart from the shaft supports of the lever and rotor so as to transmit the rotation of the lever, one end to the connecting member and the other end to the connecting member; The lever includes a spring supported by a frame, and the lever includes an elongated operating section extending from the pivot support and capable of rotating from a substantially horizontal tilted position to the upright side and vice versa, and a rotating operation section of the operating section. a short operating portion that rotates while abutting the one arm as the lever moves, and the lever is configured to engage the operating portion when the operating portion is rotated from the tilted position to the upright side. is configured to push down the one arm, and the rotor pushes down the other arm based on the transmission by the connecting member, and is held in the depressed state by an appropriate detent mechanism, while the lever When the detent mechanism is released and the operating section is returned to the tilted position, the pushing down of the arm by the operating section and the rotor is released, and the spring is oriented in a direction in which the operating section faces toward the upright position. The moving member is caused to project downward from the frame by pushing down the arm based on the rotation of the lever, and the moving member is caused to project downward from the frame by releasing the pushing down by returning the lever. A support structure for moving heavy objects, characterized in that the frame can be lifted inward.
