Abstract:
A weighing system for use on beds with legs, each leg having a bottom weight supporting surface, comprising:a plurality of removably attachable load cells, each load cell comprising a horizontally disposed floor engaging base, an upper surface, a weight measuring device and a first fastener receiving aperture in a sleeve opening out of said upper surface; a bed leg cup having an enclosed side wall and a bottom wall, said cup adapted to receive a bed leg therein for limited vertical movement, said cup further having a second fastener receiving aperture in said bottom wall and a leg fastener receiving slot in said side wall; a load cell fastener inserted through said second fastener receiving aperture into said first fastener receiving aperture, thereby coupling said load cell to said bed leg cup through said bottom wall, said fastener having a head of a diameter exceeding said fastener receiving aperture and exposed for engagement by said bottom weight supporting surface of said leg; a leg fastener inserted into said leg fastener slot and threaded into said leg to permit limited vertical movement between said cup and said leg; and a weight data collector attached to said load cell to collect and display weight measurement generated by said load cell, whereby predominantly vertically directed forces are transmitted to said load cell and side directed or off center forces are minimized.
