Claims

[Claims for Utility Model Registration] (1) A planar part of a movable bed, etc., in which the plane of the bed part is bent by a divided structure, is characterized in that it is constructed to simulate at least a spinal curve; , and the planar bed section having the spinal curve has a fulcrum in the center, and has a fulcrum shaft in which the weight generated on the bed section is always distributed equally through the fulcrum and an elastic spring. Spinal curve type isobaric bed. (2) The bed parts of the head and leg parts of the divided bed parts are expandable and retractable based on the central bed part, and can be bent around the apex of the curve corresponding to the knee part, and A spinal curve type isobaric bed having a fulcrum shaft according to claim 1, which can be freely stopped in any position. (3) Registration of a utility model in which the elastic springs provided under the flat surface of the bed section have independent functions that create elastic reaction force while maintaining the configured spinal curve without changing the surface of the bed section. A spinal curve type isobaric bed having a fulcrum shaft according to claims 1 and 2.
