Abstract
A hand tool generally includes a tool mount that removably receives thereon a tool. The tool mount and tool cooperate to provide the hand tool with a variable angle of attack with an enhanced power ratio for accommodating aged, arthritic and otherwise handicapped people.
Claims17
A hand tool, comprising:
- an upright hollow half sphere integrally attached to an elongate upper handle extender;
- an upper handle coupled to a proximal end of said upper handle extender;
- an upper tool having an integrally formed upper tool socket, said upper tool socket adapted to be received on said upright hollow half sphere to enable said upper tool to freely rotate in an x-axis plane relative to said upright hollow half sphere;
- an inverted hollow half sphere integrally attached to an elongate lower handle extender;
- a lower handle coupled to a proximal end of said lower handle extender;
- a lower tool having an integrally formed lower tool socket, said lower tool socket adapted to be received on said inverted hollow half sphere to enable said lower tool to freely rotate in an x-axis plane relative to said inverted hollow half sphere;
- and
- said upper tool and said lower tool being mounted together to effect their simultaneous rotational movement in a horizontal plane or to effect their simultaneous pivotal movement in a vertical plane.

A hand tool, comprising:
- a spring loaded leverage tool having an object engaging distal end and a tool mount engaging proximal end;
- and
- a hand held tool mount to facilitate providing said leverage tool with x-axis motion relative to said tool mount for tool operation with a variable angle of attack on an object;
- wherein said leverage tool includes an upper tool member and a lower tool member mounted pivotally together to provide the leverage tool with y-axis motion about its object engaging distal end and about its tool mount engaging proximal end;
- wherein said leverage tool further includes at least one compression spring for holding said upper tool member and said lower tool member in an open non-object engaging position at about its object engaging distal end and for holding simultaneously said upper tool member and said lower tool member in a closed tool mount engaging position at about its tool mount engaging proximal end so said leverage tool remains secured to said handheld tool mount to achieve a desired tool operation on an object;
- wherein said hand held tool mount includes:
- an upper handle member and a lower handle member, said upper handle member and said lower handle member being mounted pivotally together to further facilitate providing a leverage advantage;
- an elongate upper bar member coupled between said upper handle member and said upper tool member for spacing them a sufficient distance apart to still further facilitate providing a leverage advantage and to enable a substantial friction free rotational movement between said upper handle member and said upper tool member;
- and
- an elongate lower bar member coupled between said lower handle member and said lower tool member for spacing them a sufficient distance apart to still further facilitate providing a leverage advantage and to enable a substantial friction free rotational movement between said lower handle member and said lower tool member;
- and
- wherein said upper elongate bar member has a proximal end adapted to be coupled to said upper handle member and a distal end with an integrally formed upper tool mount;
- wherein said upper tool mount is adapted to be received within an upper tool socket integrally formed within said upper tool member so that said upper tool member can freely rotate in an x-axis plane relative to said upper tool mount;
- and
- wherein said lower elongate bar member has a proximal end adapted to be coupled to said lower handle member and a distal end with an integrally formed lower tool mount;
- wherein said lower tool mount is adapted to be received within a lower tool socket integrally formed within said lower tool member so that said lower tool member can freely rotate in an x-axis plane relative to said lower tool mount;
- wherein said upper tool member and said lower tool member rotate simultaneously in a horizontal plane to a user selected rotational angle of between about 90 degrees to the right and about 90 degrees to the left;
- and
- wherein said upper tool member and said lower tool member pivot simultaneously in a vertical plane by simultaneously pivoting said upper handle member and said lower handle member over a sufficient distance for effecting a user selected tool operation.
