ABSTRACT:
FIELD OF THE INVENTION
This invention relates to improved methods and apparatus for hand tools such as ratchet wrenches and lug wrenches.
BACKGROUND OF THE INVENTION
Various hand tools are known in the art. Ratchet wrenches and lug wrenches are known. There is a need for better hand tools for specific purposes.
SUMMARY OF THE INVENTION
The present invention in one embodiment provides a apparatus comprising a first handle a second handle, and a ratchet device. The ratchet device has an attachment device and a base. The attachment device is rotatable with respect to the base either clockwise or counterclockwise but not both. The ratchet device has a left side and a right side, and the first handle is connected to the base of the ratchet device at the left side of the base. The second handle is connected to the base of the ratchet device at the right side of the base.
The first and second handles can be an elongated bars each having a first end and a second end. The first handle can be connected at its first end to the left side of the base of the ratchet device while the second handle is connected at its first end to the right side of the base. The first ends of the first and second handles may have extensions. The base of the ratchet device may have a recess on its left side and on its right side. The first handle can be connected to the left side of the base of the ratchet device by inserting the extension of the first end of the first handle into the recess on the left side of the base of the ratchet device and the second handle can be connected to the right side of the base of the ratchet device by inserting the extension of the first end of the second handle into the recess on the right side of the base of the ratchet device.
In some embodiments the first handle and the second handle can be disconnected from the base of the ratchet device.
The extensions of the first and second handle may have threads on them and the recesses on the left side and right side of the base of the ratchet device may have internal threads on its inner surface so that the first handle and the second handle can be screwed into the left side and the right side of the base of the ratchet device, respectively. The extensions of the first and second handle may have springy devices connected to them so that they can be inserted into the recesses of the base of the ratchet device and held to the base.
In some embodiments, the second handle can be disconnected from the base of the ratchet device, the first handle has a recess at its second end, and the second handle can be connected to the first handle by inserting the extension of the first end of the second handle into the recess at the second end of the first handle.
