BOTTOM LIFTER AND BED HAVING SAME

摘要

PROBLEM TO BE SOLVED: To provide a bottom part elevator which allows turn-over, back and leg elevation, and which is cost effective, and a bed having the elevator attached. SOLUTION: Elongated air bags 1 are butted with each other and connected parallel with a sheet 2. A small hole is bored so that air flows through all of these air bags 1. A hose 3 and foot pump 4 are attached to an air bag 1a at one end of the air bag sheet. Surface fasteners 5 are fixed to both ends 1a and 1b of the air bag sheet. The surface fasteners 5 are attached to the floor with less spacing in between than the width of the sheet 2. This allows a set of air-filled bags 1 to be arched and requires a less amount of air for lifting the bottom of the air bag sheet.
