Abstract
Abstract A mechanics creeper has a molded body shell with upturned peripheral edges or walls forming a receiving area within the walls for receiving the head and torso of a user. Wheels are mounted on the body shell so that the shell can easily roll over various types of surfaces with the upturned peripheral walls protecting the user from water, mud, or other materials and from striking unseen objects as the creeper is moved. The wheels may be removable so that the body shell, having a smooth outside contour, may slide over surfaces such as mud, sand, or snow, or through rubble were wheels are unuseable.
