Abstract
Guards for covering rotating discs of power hand tools wherein said guard includes a movable guard for covering a normally exposed portion of a disc and which is pivotably mounted relative to a body of the power tool such that the it is movable from a first covering position in a plane substantially parallel to a rotational plane of the disc to a second withdrawn position in which the movable guard extends generally transversely to the rotational plane of the disc thereby allowing maximum disc coverage yet permitting disc use in restricted spaces.
Claims20
A method of providing protection by way of a guard covering a portion of a rotary disc of a hand held power tool wherein the power tool includes a body from which extends a rotating disc, the method comprising:
- a) providing a movable guard,
- b) providing a mounting member for securing the movable guard relative to the body of the power tool;
- c) pivotally mounting the movable guard relative to the mounting member so as to be movable from a first position extending generally parallel to a rotational plane of the rotating disc and intermediate the rotating disc and the body of the power tool to a second position wherein the movable guard extends transverse to the rotational plane of the rotating disc;
- and
- d) resiliently urging the movable guard toward the first position.
A guard apparatus for use with a hand held rotary power tool having a body from which extends a rotating disc, the apparatus including, a movable guard, mounting means for mounting the movable guard to the body of the tool, pivot means for pivotally mounting the movable guard relative to said mounting means so as to be movable from a first covering position adjacent the rotating disc and extending generally parallel to a rotational plane of the rotating disc to a second retracted position extending transversely with respect to the rotational plane of the rotating disc, and resilient means for resiliently urging said movable guard toward said first position.
An apparatus for providing a guard for a hand held power tool having a body and a rotating disc, the apparatus comprising, a guard including a movable guard section and a fixed guard section, mounting means for mounting said fixed guard section to the body of the tool such that said movable guard section and fixed guard section extend outwardly between the rotating disc and the body of the power tool, pivot means for pivotally connecting said movable guard section to said fixed guard section whereby said movable guard section is movable from a first position extending generally parallel to a rotational plane of the rotating disc of the power tool to a second position extending transversely thereto, and urging means for resiliently urging the movable guard section toward said first position.
