Abstract
A hand tool for servicing a power tool or other host tool is adapted to be readily mountable to and dismountable from the host tool via magnetic coupling. The hand tool includes a handle body, and a nut driver supported on the handle body. The handle body may define a bifurcated support, and the tool may include a pivot pin extending through the bifurcated support and the nut driver to support the nut driver on the tool. The nut driver defines at least one socket region dimensioned to receive a nut, and further is magnetized for magnetic coupling with a nut positioned within the socket region. In one embodiment, the nut driver houses a discrete magnet for this purpose. A second magnet may be supported on the handle body toward its central portion.
Claims16
A hand tool for servicing a device comprising a nut fastener, the hand tool comprising:
- a longitudinally extending handle body, said handle body defining a bifurcated support;
- a pivot pin extending through said bifurcated support transversely to an axis of elongation of said handle body;
- a nut driver supported on said pivot pin for pivotable motion between a first position, in which an axis of said nut driver extends in a direction of an axis of elongation of said handle body, and a second position, in which the axis of said nut driver extends transversely to the axis of elongation of said handle body, said nut driver defining a socket region dimensioned to receive a nut;
- a first magnet supported in said nut driver in position to couple magnetically with the device's nut positioned within said socket region;
- and
- a second magnet supported on said handle body intermediate a length of said handle body to magnetically couple with said device when said first magnet is magnetically coupled with said nut and said nut driver is in said second position;
- and
- a slotted shaft supported in sliding relationship to said handle body, said slotted shaft having at one end a screwdriver tip, said slotted shaft being slidable between a retracted position, in which said screwdriver tip is housed within said handle body, and an operative position, in which said screwdriver tip is extended beyond said handle body and exposed for use, and said slotted shaft defines a longitudinally extending raceway, an opening for receiving a set screw extending transversely of said raceway, a spring-securing feature at an end opposite said screwdriver tip, wherein said slotted shaft further defines a transversely-extending through-opening, wherein said handle body supports a slidable release plunger supporting a pin positioned in said through-opening, said hand tool further comprising a retraction spring secured to said spring-securing feature to retract said slotted shaft when said pin exits said through-opening.

A hand tool comprising:
- a longitudinally extending handle body;
- a nut driver supported on said handle body for pivotable motion relative thereto, said nut driver defining a socket region dimensioned to receive a nut;
- a magnet supported on said handle body intermediate a length of said handle body, wherein at least one of a size and a strength of said magnet is selected to ensure said handle remains securely coupled to a power tool during operation of said power tool;
- and
- a slotted shaft supported in sliding relationship to said handle body, said slotted shaft having at one end a screwdriver tip, said slotted shaft being slidable between a retracted position, in which said screwdriver tip is housed within said handle body, and an operative position, in which said screwdriver tip is extended beyond said handle body and exposed for use, and said slotted shaft defines a longitudinally extending raceway, an opening for receiving a set screw extending transversely of said raceway, a spring-securing feature at an end opposite said screwdriver tip, wherein said slotted shaft further defines a transversely-extending through-opening, wherein said handle body supports a slidable release plunger supporting a pin positioned in said through-opening, said hand tool further comprising a retraction spring secured to said spring-securing feature to retract said slotted shaft when said pin exits said through-opening.

A hand tool comprising:
- a longitudinally extending handle body;
- a nut driver supported on said handle body for pivotable motion relatively thereto, said nut driver defining a socket region dimensioned to receive a nut of an associated device, said nut driver being magnetized to couple magnetically with a nut positioned within said socket region;
- a magnet supported on said handle body intermediate a length of said handle body to magnetically couple with a housing of said associated device when said nut driver is magnetically coupled with said nut:
- and
- a slotted shaft supported in sliding relationship to said handle body, said slotted shaft having at one end a screwdriver tip, said slotted shaft being slidable between a retracted position, in which said screwdriver tip is housed within said handle body, and an operative position, in which said screwdriver tip is extended beyond said handle body and exposed for use, and said slotted shaft defines a longitudinally extending raceway, an opening for receiving a set screw extending transversely of said raceway, a spring-securing feature at an end opposite said screwdriver tip, wherein said slotted shaft further defines a transversely-extending through-opening, wherein said handle body supports a slidable release plunger supporting a pin positioned in said through-opening, said hand tool further comprising a retraction spring secured to said spring-securing feature to retract said slotted shaft when said pin exits said through-opening.
