Is installed. The elevating body 11 may be a heavy object such as a table in addition to the wash basin, and is not limited thereto. A pinion gear 13 forming a part of the holding means is rotatably supported on the vertical frame 5a below the movable frame 5 by meshing with a rack gear 15 forming a part of the holding means attached to the vertical frame 3a. . A large-diameter braking drum 17 is coaxially mounted on the pinion gear 13, and on the outer peripheral surface of the braking drum 17, one end is fixed to a vertical frame 5a. Brake shoe 19
Is enclosed. On the other hand, an operation lever 21 which constitutes a part of the holding release means is rotatably supported on the mounting frame 9 at a required angle (width), and the operation end of the operation lever 21 is connected to the other end of the brake shoe 19. Are linked. The operation lever 21 is normally rotated and biased by an elastic member (not shown) such as a compression spring or a tension spring so that the brake shoe 19 is pressed against the outer peripheral surface of the brake drum 17. The operation lever 21 and the other end of the brake shoe 19 include a link arm 20 whose one end is rotatably supported at an operating end of the operation lever 21, and a movable frame 5 which is an intermediate part.
The other end is connected to the other end of the link arm 20 and the other end is connected to the link lever 22 to which the other end of the brake shoe 19 is attached, so that the operation lever 21 can be gripped. Accordingly, the link lever 22 is swung so that the brake shoe 19, which is always in pressure contact with the outer peripheral surface of the brake drum 17, is released by the elastic force of the elastic member to release the braking. Note that a mechanism that swings the link lever 22 by directly connecting the other end of the operation lever 21 and the link lever 22 with a wire without using the link arm 20 may be used. A rotating body 23 such as a sprocket or gear is rotatably supported on the upper frame 3b of the fixed frame 3, and one end of a connecting member 25 such as a chain and a timing belt wound around the rotating body 23 is fixed to the movable frame 5. Have been. The balance member 27 is attached to the other end of the connecting member 25. The balance member 27 has a weight that at least substantially coincides with the body 11 to be lifted, desirably substantially the total weight of the movable frame 5 and the body 11 to be lifted, and is balanced with the movable frame 5 including the body 11 to be lifted. still,
When the object 11 is a wash basin, the weight of the balance member 27 may be set to the weight obtained by adding the weight of the water stored in the wash basin to the above-mentioned weight.
