Abstract

The present invention discloses a fixture (100) configured to file a chain (202) of a chain saw. The fixture (100) includes at least one pair of flanges (102A, 102B), wherein each flange of the at least one pair of flanges (102A, 102B) has a first end (104A, 104B) and a second end (106A, 106B). Further, a first connecting portion (111) connects the flanges (102A, 102B) at their first ends (104A, 104B), and a second connecting portion (113) connects the flanges (102A, 102B) at their second ends (106A, 106B). Further, the first connecting portion (111) includes a pair of counter holds (112, 114) configured to provide area contact with a guide bar (208) of the chain saw. The fixture (100) also includes a cam portion (116) pivotally coupled to the second connecting portion (113), wherein the cam portion (116) and at least one of the counter holds (112, 114) simultaneously secure the fixture (100) to the guide bar (208).

Description

technical field [0001] The present invention relates generally to sharpening chainsaw chains and, in particular, to a filing fixture guide for assisting manual filing of chainsaw chains. Background technique [0002] The cutting links of the chain in a chain saw dull at an unpredictable rate that depends on a number of parameters. For example, the type of wood, the moisture content of the wood, and the force applied by the operator of the chainsaw, among others, may be some of the variables that determine the rate at which the cutting links dull. A chainsaw with dull cutting links not only cuts slowly but is also detrimental to the safety of the operator due to the increased effort and force required to drive the saw through wood. [0003] One solution for the operator is to replace the chain, a process that requires not only the supply of additional chain but also specialized tools and suitable work surfaces. Typically, in field work situations, this option is not employe...
