Abstract
A rotary power tool, such as a router, includes an actuating device engaged with a chuck device to move the chuck device between its gripping and release positions. The actuating device includes a lever member that extends axially relative to a casing of the power tool within an inner circumference of a base member. This lever member is movable relative to the casing and is engaged with the chuck so that movement of the lever is imparted to the chuck device causing the chuck device to move axially between its gripping and release positions.
Claims20
A rotary power tool having a remotely actuated chuck device, said power tool comprising:
- a casing housing a rotationally driven drive spindle;
- a chuck device attached to an end of said drive spindle, said chuck device movable between a gripping position wherein said chuck device clamps upon a tool held therein, and a release position wherein said chuck device releases a tool held therein;
- an actuating device operably engaged with said chuck device to move said chuck device between said gripping and release positions;
- a base concentric on said casing, said base comprising a variably positionable upper working surface establishing a working position of said tool held by said chuck device relative to a work piece, said base rotatably advanceable on said casing for changing positions of said working surface relative to an axis of said drive spindle;
- and
- wherein said actuating device further comprises a lever member extending axially relative to said casing within an inner circumference of said base, said lever member movable relative to said casing to move said chuck device between said gripping and release positions with said base being freely rotatable relative to said casing without interference from said lever member.
A rotary power tool having a remotely actuated chuck device, said power tool comprising:
- a casing housing a rotationally driven drive spindle;
- a chuck device attached to an end of said drive spindle, said chuck device comprising an outer sleeve member axially movable between a gripping position wherein said chuck device clamps upon a tool held therein, and a release position wherein said chuck device releases a tool held therein;
- a base concentric on said casing, said base comprising a variably positionable upper working surface establishing a working position of said tool held by said chuck device relative to a work piece, said base axially adjustable on said casing for changing positions of said working surface relative to an axis of said drive spindle;
- an actuating device having a first member engaged with said outer sleeve member and extending generally radially outward from said chuck device, said first member movable in a direction so as to move said outer sleeve member between said gripping position and said release position;
- and
- said actuating device further comprising a lever member engaged with said first member and extending generally axially relative to said casing so that said base is movable relative to said casing without interference from said lever member, said lever member movable relative to said casing wherein movement of said lever member is imparted to said first member.
