Mobility-disabled portable weighing device

Details

Inventors: Garfinkle, Moishe;
Assignee:
Primary Examiner: Miller, Jr.; George H.
Assistant Examiner:
Attorney, Agent or Firm:

A portable weighing device comprising two laterally displaced, electrically connection and rigidly aligned weighing modules is disclosed that permits convenient weighing of the mobility-disabled while occupying a conventional manually-operated wheelchair supported by two front caster wheels and two rear main wheels. The portions of the weight of the wheelchair supported by each wheel is successively summed and the tare is electronically subtracted. The weight of the occupant is then displayed. Accordingly with the weighing device wheelchair users can be conveniently weighted at rehabilitation centers, physician's offices or hospital clinics, or alternatively can weight themselves at their residence. The weighing device can be folded for carriage or storage.

DETAILED DESCRIPTION What is claimed is: 1.
A portable weighing device for the mobility-disabled comprising a pair of modules configured with weighing platforms and provided with a) mechanical means to slideably secure and rigidly align said modules, and b) electronic means to register, calculate and display weights; whereupon said modules are laterally displaced on an essentially level floor for determining the weight of an occupant of a manually-operated wheelchair, said wheelchair supported by two conventional front caster wheels and two conventional rear main wheels, said weighing platforms accommodating various treads and wheelbases of said caster and main wheels, said determination of said weight of said occupied wheelchair made in a sequence of steps comprising initially rolling said caster wheels onto said weighing platforms and subsequently rolling said main wheels onto said weighing platform, causing said wheelchair to tilt during both said steps, whereupon: a) initially the portion of said weight of said occupied wheelchair supported solely by said caster wheels is imposed on said weighing platform and registered by said electronic means, and b) subsequently the portion of said weight of said occupied wheelchair supported solely by said main wheels is imposed on said weighing platform and registered by said electronic means; whereby weight of said occupant, compensated for variations in said tread, wheelbase and tilt of said wheelchair, is calculated from said weight of said occupied wheelchair by said electronic means from said sequence of steps and shown on said display.
2.
A portable weighing device according to claim 1 wherein said mechanical means to slideably secure and rigidly align said modules are provided by a slider and a pivot arrangement comprising lateral slide rods and a pivot; whereby said modules can be either deployed for weighing by extension of said slider and said pivot or folded and secured together for carriage or storage by retraction of said slider and said pivot
