<p>PROBLEM TO BE SOLVED: To match a stretching part of a human body positionally different depending on the physical constitution of a user by arranging a strip-shaped bottom bendable only to one side on the bottom of a Gatch bed or the like to adjust the bending point thereof. SOLUTION: A knee bottom 1a and a foot bottom 1b are interlinked by a strip-shaped bottom 2 in which strip-shaped bottom members 2a-2d are linked sequentially so as to be bendable only to one side at several points. A slide metal fitting 4 is provided on support frames 3 for supporting the knee bottom 1a to allow advancing or retracting thereof. Fixing holes 5 provided near the side of the tip of the support frames 3 are positioned to match fixing position adjusting holes 6a-6c provided on the side of the slide metal fittings 4 and fixing pins are inserted into the holes so that the support frames 3 and the slide metal fittings 4 can be loaded or unloaded to be adjusted and fixed by three stages.</p> |
