Abstract:

A guard for a chain saw of the type having a housing and an elongated saw blade projecting outwardly from the housing including an endless chain having an upper run and a lower run includes an elongated guard arm having a generally arcuately-shaped cross-section, and a spring-loaded hinge pivotably connecting the guard arm at one of its ends to the housing for movement between a first and second end position. In the first end position, the guard arm overlies and extends above the upper run of the chain in a spaced-apart generally parallel relationship thereto, and in the second end position, the guard arm extends upwardly generally normally relative to the chain upper run. The guard arm is resiliently biased by the spring-loaded hinge so that it normally assumes and is urged into the first end position thereof.
