Claims

[Claims for Utility Model Registration] A storage device that can be stored upright around a support shaft 4 provided at one end and switched to a state of use by lying down, and has a balance device that balances the moment around this support shaft 4. In the bed 1, this balance device is arranged between the fixed base 2 on which the support shaft 4 is provided and the storage bed 1, and is compressed and narrowed when standing up and expanded when fell down, and is elastically biased by a spring 20 in the contraction direction. A storage bed comprising a pantograph mechanism 6 in which links 7 to 10 are arranged in a parallelogram shape. In the pivoting portions of the links 7 to 10 constituting the top and bottom of the pantograph mechanism 6 according to the claims, each of the links 7 to 10 has gear portions 7a to 10a.
A storage bed is formed by forming these gear parts 7a to 10a and meshing them with each other. A storage bed in which the storage bed 1 according to claims or descriptions is installed in an upright state on a movable platform 27 on which a movable rail 25 is movably installed on a fixed rail 23 via wheels 26. A storage bed according to the claims, wherein the storage bed 1 rises and falls in a lateral direction perpendicular to the moving direction of the movable table 25.
