中央部にハンドルが取着された床開口部の蓋自立装置。The opening frame is attached to the periphery of the opening in the floor, and the opening frame can be freely opened and closed between the closing position and the opening position by rotating the opening frame with the rear edge remaining on the rear edge of the opening frame. One end is rotatably pivoted to the side edge of the cover plate, and a claw piece is formed on the other end so that it can be moved up and down in a through hole that passes vertically through the side edge of the opening frame. The end portion of the arm to be inserted is slidably installed in a long hole formed along the side edge of the cover plate at a rear position on the side edge of the cover plate from the pivot point between the cover plate and the arm. The lever is provided with a lever and a spring means for biasing the lever toward the front of the cover plate, and when the cover plate is open, the lever is moved forward of the cover plate by the spring force of the spring means and touches the end of the lever. Rotate the contacting arm around the shaft mounting part, lock the claw piece of the arm to the periphery of the through hole, so that the cover plate stands on its own without falling back and forth, and move the lever backwards to connect the claw piece of the arm and the transparent hole. The lid plate is closed by releasing the connection with the hole periphery, and the lever is installed between the both side edges of the lid plate on the back side of the lid plate, and the lever is attached to the floor opening with a handle attached to the longitudinal center of the lever. Lid stand-alone device.
