Abstract
A quick insert and quick release tool holder for gripping the handle of a tool, or the like. The tool holder has a disk-shaped flexible friction holder with a central aperture for gripping around a tool handle. A release mechanism is operable by the use of only one hand to expand the aperture and release the tool handle.
Claims6
A tool holder comprising:
- a disk-shaped flexible member having a circular aperture, the flexible member associating with means for peripherally clamping the flexible member therearound, said aperture capable of resiliently expanding to grip around a tool handle when axially inserted therethrough in one direction;
- and,
- release means for pushing against the flexible member around the circular aperture in the same axial direction as during insertion of a tool handle held therein whereby to increase the aperture size to release the tool handle, said release means comprises a pivoting release member and a tube member, said tube member having an upper annular portion being larger in diameter than said circular aperture and capable of being moved by said pivoting release member upwardly against the flexible member around the circular aperture to expand the circular aperture.
A quick insert and quick release tool holder for gripping the handle of a tool, or the like, the tool holder comprising:
- a hollow upper bonnet member;
- a hollow lower body releasably attached to the upper bonnet member and defining a chamber therein, the lower body having an interior ledge means therearound;
- a disk-shaped flexible member having a central aperture therethrough, said flexible member being peripherally clamped inside said defined chamber;
- a release tube means below said flexible member, the release tube means having an upper lip, the upper lip having a diameter larger than the aperture of the flexible member and arranged for contact against the flexible member, said release tube means being upwardly movable;
- support ring means holding said release tube means in freely movable axial relationship therewith, said support ring means including a peripheral portion extending underneath said flexible member and the peripheral portion being atop said interior ledge means of said lower body, said support ring means including a bracket means depending therefrom;
- a release member having a manually operable pivot arm joined to a pivoting ring, said release member being pivotally supported by the bracket means of said support ring means, the pivoting ring extending around said release tube means and being in movable contact therewith whereby upon manually operating the pivot arm the pivoting ring pivots to contact and urge said release tube means upwardly to contact the flexible member and expand the aperture thereof, said pivot arm extending downwardly from said lower body through a slot in said lower body.
