Abstract

The tool handle of the invention includes a shank connected via a ratcheting mechanism to a male square drive. A pair of handle wings are pivotally connected to the shank at a transverse pivot hinge such that the handle wings can be changed between a screwdriver-type configuration, an L-shape configuration, a T-shape configuration or other intermediate configurations. When the handle wings are in the fully open position, the handle wings bear against the shank to create a mechanism for transferring power between the handle wings and the tool shank without the need for a separate lock. A quick change adapter having a female drive can be connected to the male square drive such that the tool handle can be used with a wide variety of tools including taps and extractors, sockets, screwdriver bits and the like.

Claims

1. A tool handle for holding a tool operatively connected to one end of the tool handle, the tool handle comprising:

a shank supporting a connector;

a first handle portion;

a second handle portion;

said first and second handle portions forming an entire gripping portion of the handle;

said first and second handle portions each having an end pivotally connected to the connector and a free end;

said first and second handle portions movable between a first position where the first handle portion and second handle portion extend along the longitudinal axis of the shank and away from the shank in the same direction, and a second position where the first and second handle portions extend substantially perpendicularly away from the longitudinal axis in opposite directions, and a third position where the first and second handle portions are on the same side of the longitudinal axis and extend substantially perpendicularly away from the longitudinal axis in the same direction.

2. The tool handle according to claim 1 wherein said first and second handle portions are in load bearing contact with said shank in a first position.

3. The tool handle according to claim 1 wherein the shank is connected to a tool connector via a ratchet.

4. The tool handle according to claim 1 wherein the shank is connected to a tool connector, said tool connector being a male connector.

5. The tool handle according to claim 1 wherein said first and second handle portions are pivotally connected to the shank at a common pivot hinge.

6. The tool handle according to claim 5 said first and second handle portions and said shank including interdigitated portions forming said pivot hinge.

7. The tool handle according to claim 1 further including a locking mechanism for locking the first and second handle portions in a desired position.

8. The tool handle according to claim 7 wherein the locking mechanism includes a ball biased into engagement with the first and second handle portions.

9. The tool handle according to claim 6 wherein the interdigitated portions include at least two portions each of said first handle portion, said second handle portion and said shank.

10. The tool handle according to claim 3 wherein the ratchet is permanently attached to the shank.

11. The tool handle according to claim 9 wherein the interdigitated portions receive a pivot pin.

12. The tool handle according to claim 6 wherein the interdigitated portions include at least three portions each of said first handle portion and said second handle portion.

15. The tool handle according to claim 1, wherein in all positions between which the first and second handle portions are movable, the first and second handle portions each form an angle of not less than substantially 90 degrees with the longitudinal axis of the shank from the connector towards the end of the tool handle adapted to be connected to the tool.

13. A tool handle for holding a tool operatively connected to one end of the tool handle, the tool handle comprising:

a shank supporting a connector;

a first handle portion;

a second handle portion;

said first and second handle portions forming an entire gripping portion of the handle;

said first and second handle portions each having an end pivotally connected to the connector and a free end;

said first and second handle portions movable between a first position where the first handle portion and second handle portion extend along the longitudinal axis of the shank and away from the shank in the same direction, and a second position where the first and second handle portions extend substantially perpendicularly away from the longitudinal axis in opposite directions, and a third position where the first and second handle portions are on the same side of the longitudinal axis and extend substantially perpendicularly away from the longitudinal axis in the same direction;

a screw extends in the shank along the longitudinal axis and rotatably connects the connector to the shank, said screw supports a ball for locking the handles in the first position, second position and third position.

16. The tool handle according to claim 13, wherein in all positions between which the first and second handle portions are movable, the first and second handle portions each form an angle of not less than substantially 90 degrees with the longitudinal axis of the shank from the connector towards the end of the tool handle adapted to be connected to the tool.

14. A tool handle for holding a tool operatively connected to one end of the tool handle, the tool handle comprising:

a shank supporting a connector;

a first handle portion;

a second handle portion;

said first and second handle portions forming an entire gripping portion of the handle;

said first and second handle portions each having an end pivotally connected to the connector and a free end;

said first and second handle portions movable between a first position where the first handle portion and second handle portion extend along the longitudinal axis of the shank and away from the shank in the same direction, and a second position where the first and second handle portions extend substantially perpendicularly away from the longitudinal axis in opposite directions, and a third position where the first and second handle portions are on the same side of the longitudinal axis and extend substantially perpendicularly away from the longitudinal axis in the same direction;

said first handle portion includes a first flange and second handle portion includes a second flange and said shank includes a third flange interdigitated with said first and second flanges to form a pivot hinge where said first flange includes a first plurality of detents and said second flange includes a second plurality of detents where selected ones of the first plurality of detents and second plurality of detents are aligned in the first, second and third positions to define recesses for receiving a single locking member.

17. The tool handle according to claim 14, wherein in all positions between which the first and second handle portions are movable, the first and second handle portions each form an angle of not less than substantially 90 degrees with the longitudinal axis of the shank from the connector towards the end of the tool handle adapted to be connected to the tool.
