<p><P>PROBLEM TO BE SOLVED: To provide a lifting storage device which can smoothly lift a storage shelf without complicating a structure of a winding drum, and can reduce load to a body of a user when the storage shelf is lifted. <P>SOLUTION: The lifting storage device 1 includes: an outside box 10 having an opening 15 at an under surface side; a storage shelf 20 which is made to freely lift between a position stored in the outside box and a position protruding from the opening of the box toward a lower position; a winding drum 41 winding around a string like member 47 which hangs the storage shelf to the outside box; and a biasing means 46 which energizes the winding drum to a direction of winding, wherein the winding drum is formed so that a winding radius may decrease continuously toward a winding termination 43b side from a winding beginning 43a of the string like member, and a maximum rotation angle is made less than 360°at the time of lifting of the storage shelf, and winds around the string like member along a rotation axis direction of the winding drum at the same position. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
