摘要

PURPOSE: To constitute the bottom structure of bed so that it can be fitted to the body of a user, and the deviation of mattress on the bottom can be also prevented. ;CONSTITUTION: In connecting parts of a back bottom 1a and a waist bottom 1b, and the waist bottom 1b and a knee bottom, a flexible relay bottom 2 is provided so as to connect the back bottom 1a and the waist bottom 1b, and the waist bottom 1b and the knee bottom. Also, on the relay bottom 2, a nonskid member 3 of a mattress is arranged. In such a way, when a floor part is elevated and declined, the bend angle of the connecting part of the floor part becomes moderate so as to be fitted to the body of a user, and a deviation of the mattress on the bottom can be also prevented.;COPYRIGHT: (C)1995,JPO
