Abstract
A sheet material sling is supported on a horseshoe-shaped device mounted on three casters which forms a vehicle to support a knee of a user. Two such supports are used, unconnected to each other by users who must kneel in their work and must scoot along a support surface. Provisions are made for the supports to be interconnected by a flexible connector or by a rigid table like sheet.
Claims20
A pair of mobile knee supports comprising two identical wheeled vehicles, each designed to receive and support a human knee;
- each said support including an outer U-shaped strip and an inner U-shaped strip spaced concentrically apart, three spaced casters located respectively at the center of said strips and at both ends of said strips;
- a rigid support for each said caster depending downwardly from at least one of said strips;
- and a flexible knee support sheet material suspended from said inner strip and adapted to receive said knee and to suspend the knee above the lowest level of said casters.
A knee support device comprising two horseshoe-shaped strips concentrically spaced apart from each other at the same general horizontal elevation to form an inner strip and an outer strip, at least three rigid spacer members to maintain the spacing between said strips;
- three spaced L-beam members each having a vertical leg and a horizontal leg;
- the vertical legs being rigidly attached, respectively, to said inner strip and said horizontal legs being spaced below said inner strip and positioned to lie in a common plane, a caster attached to, and depending downwardly from, each said horizontal leg;
- a flexible sheet material sling attached to said inner strip adjacent said L-beams and adapted to receive a knee therein and support it at an elevation above the lowest elevations of said casters;
- and at least one tool-carrying pouch suspended between said outer and inner strips adjacent said sling.
A mobile knee support apparatus comprising a pair of identical wheeled vehicles, each said vehicle being designed to receive and support respective knees of a user, each said vehicle including a U-shaped framework having a rigid outer member with a pair of spaced side wall portions and a front wall portion and a completely open space bounded by said side and front wall portions, said side wall portions terminating in opposite free end portions, three spaced casters attached respectively to said front wall portion of said framework and to said free end portions, and a flexible knee support sheet material suspended from said front and side wall portions of said framework, said sheet material having a lower surface portion extending downwardly from each front and side wall portion to a position in the general plane of said casters to position knees of a user closely adjacent to and above a surface on which said casters are rotatably supported.
