Abstract
A device for installing a tire chain is a one-piece, rugged tool made of ⅜″ or ½″ steel stock. The tool has a total length of approximately 1 foot. At a first end, the tool has an arcuate shape that terminates in an open channel, which channel functions to grab a chain hook and to lever the hook into engagement with a chain link. The second end of the tool is L-shaped and terminates in an elliptical-shaped member dimensioned to fit a conventional cam-loc tightening device.
Claims8
A tire chain tool, comprising:
- an elongate tubular body member having a proximate end and a distal end;
- an arcuate portion defining said proximate end of said tubular body, said arcuate portion having a beveled inside surface and terminating in an open-ended, channel-shaped tip, wherein said tubular body member and said arcuate portion meet at a junction;
- a triangular-shaped protuberance disposed at said junction;
- and
- a member for tightening a cam-loc device defining said distal end of said tubular body.
