  • Apparatus for weighing wheeled or wheel-supported loads
    Patent number: 6380496
    Abstract: An apparatus (10) for weighing wheeled or wheel- or caster-supported loads, including non-ambulatory patients confined to wheeled beds, which combines lift, support, and weight-measuring functions. The apparatus (10) is lightweight, portable, and employs a foot-activated lever-based design, including a foot bar (51) and pivoting wheel receptacle (50), for raising both the load and the load's wheeled support, if any. The apparatus (10) can be positioned for use without moving the load, and, because the apparatus utilizes leg and lower body strength, operators need not possess substantial arm or upper body strength. Thus, injuries which result from improper lifting techniques are avoided.
