  • Patent number: 8448545
    Abstract: A collapsible, multi-use tool for use in changing a flat tire includes a tool body having a first end including a curved chisel surface and a second end including a ratchet drive head. A central portion of the tool connects the two end portions, the ends of which are hingedly connected to the adjacent first and second ends. Sliding sleeves are disposed over the first and second ends and can be slid towards one another so as to cover the central portion of the tool and the hinged connections to keep the tool in a linear configuration that provides excellent leverage for breaking lug nuts loose. One of the sliding sleeves may be flared at one end so as to receive an end of the other sliding sleeve when coupled together.
