Abstract
Abstract An apparatus for supporting the weight of an individual's body includes a unit for attachment to each leg. Each unit includes a lower bar having an upper section and lower section which is longitudinally extendable from the upper section. The upper section is fitted with straps to permit attachment of the lower bar to the lower leg of the individual. An upper bar is hingeably connected to the upper end of the lower bar and a brace member, pivotable from the upper bar, is selectively positionable between the upper bar and the lower section of the lower bar. As the individual crouches into a rest position, the upper leg of the individual engages the upper bar and by engaging the brace into the lower section of the lower bar extends the lower section of the lower bar to support the unit, and the weight of the individual, from the ground.
