  • Patent number: 5556146
    Abstract: A grip for lifting and carrying gas cylinders, comprising a hoop which is circular and a handle attached to the hoop, wherein the diameter of the circle formed by the hoop is slightly larger than the diameter of the gas cylinders to be lifted and carried. In a preferred embodiment: the hoop and the handle are made from steel, and the handle is attached to the hoop by welding; the hoop is flat in a direction perpendicular to the plane of the circle formed by the hoop, so that the hoop forms a short cylinder, the axis of which passes through the center of the circle; the hoop is formed from a flat strip, which is bent to form the short cylinder; and the circle formed by the hoop is incomplete on the side where it is attached to the handle, the steel strip from which the hoop is formed being bent outward to attach it to the handle.
