Abstract
Abstract An improved mechanic's creeper includes a closed loop, unitary metal frame supported by heavy duty casters recessed at spaced intervals in the frame. The frame is comprised of a single, closed loop rectangular shape, and a single cross member attached to opposite sides of the frame to assist in support of a platform. The creeper is thus configured to define a low profile while minimizing any obstructions to the user's field of motion.

Claim 1
Independent Claim
268 words
An improved mechanic's creeper of the type including a platform for receiving a person in a reclined position, a frame for supporting said platform, and casters mounted on said frame for allowing said mechanic's creeper to creep, the improvement comprising in combination: a low profile, generally planar, rectangular frame having generally parallel, spaced sides and transverse ends formed as a continuous, closed loop tubular member having an upper surface defining a platform support plane and also having four corners, the frame thereby defining a circumference, each of said sides including two, spaced, upwardly extending caster recess bends intermediate two corners of the tubular member, said bends being opposite each other, each bend formed to receive a caster and effectively position the entire rectangular frame more nearly adjacent the floor level, each bend including a generally flat section to receive a caster; a supplemental support bracket comprising a straight, tubular member connecting the opposite parallel spaced sides of the frame intermediate the caster recess bends; a caster mounted to the lower surface of each caster recess bend attached to the flat section; a rectangular platform mounted to the upper surface of the ends of said generally rectangular frame, supported on the supplemental support bracket and defining a frame and a platform surface which is immediately adjacent the ground level and below the level of the caster bends along the entire circumference of the frame; wherein said generally rectangular frame is defined by first and second U-shaped sections integrally and identically formed as substantially mirror image sections, said sections being coupled at two joints to form said continuous closed loop.
