Abstract

A hand tool system comprises a first driver, a second driver, and a driver adapter. The first driver and the second driver each comprises a driver handle having an external configuration and a driver component secured to the driver handle. The driver adapter is selectively fittable over the driver handles of the first and second drivers. The driver adapter comprises an elongate body, a first socket formed in a first end of the elongate body, a second socket formed in a second end of the elongate body, and a plurality of through holes formed through and distributed longitudinally along a length of the elongate body. Each socket has an internal configuration sized and shaped to receive a driver handle of either the first or second driver and to transfer torque to the driver upon rotation of the driver adapter.

First claim

What is claimed is:

1. A driver adapter for use with a driver handle of a driver, and operable to transfer torque to the driver, the driver adapter, comprising:
an elongate body having a first end and a second end spaced longitudinally apart from the first end;
a first socket formed in the first end, the first socket having an internal configuration sized and shaped to receive a driver handle of a first driver, and to transfer torque to the first driver upon rotation of the driver adapter;
a second socket formed in the second end, the second socket having an internal configuration sized and shaped to receive a driver handle of a second driver, and to transfer torque to the second driver upon rotation of the driver adapter;
a third socket formed in the elongate body between the first and second sockets, the third socket having a third configuration sized and shaped to receive a driver handle of a third driver, wherein the third socket extends from the first socket to the second socket so that the third socket is accessible from both the first end and the second end; and
a plurality of through holes formed through and distributed longitudinally along a length of the elongate body between the first end and the second end, the plurality of through holes sized and configured to receive a torque lever that facilitates rotation of the driver adapter.

2. The driver adapter of claim 1 , wherein the first socket is different in size from the second socket, such that the driver adapter is operable with the first and second drivers having driver handles of different size.

3. The driver adapter of claim 1 , wherein the internal configuration of the first socket is different from the internal configuration of the second socket, such that the driver is operable with the first and second drivers being of different types, and having driver handles of different configuration.

4. The driver adapter of claim 1 , wherein the internal configuration of the first socket has a first pattern of first protrusions and the internal configuration of the second socket has a second pattern of second protrusions.

5. The driver adapter of claim 1 , wherein the internal configuration of the first socket has a first pattern of flats and the internal configuration of the second socket has a second pattern of flats.

6. The driver adapter of claim 1 , wherein the internal configuration of the first socket has a pattern of flats and the internal configuration of the second socket has a pattern of protrusions.

7. The driver adapter of claim 4 , wherein at least one of the first pattern of protrusions or the second pattern of protrusions is sized and shaped to complement a flute of a driver handle.

8. The driver adapter of claim 2 , wherein a minor diameter of the internal configuration of the first socket is greater than a major diameter of the internal configuration of the second socket.

9. The driver adapter of claim 1 , wherein the third socket comprises a major diameter less than a minor diameter of the first configuration of the first socket and a minor diameter of the second configuration of the second socket.

10. The driver adapter of claim 1 , further comprising a torque lever extending through a through hole of the plurality of through holes.

11. The driver adapter of claim 1 , wherein the torque lever comprises a rigid rod.

12. The driver adapter of claim 11 , wherein the rigid rod extends through a through holes of the plurality of through holes, such that the rigid rod extends in opposing directions from the driver adapter.

13. The driver adapter of claim 11 , wherein the torque lever comprises a flexible strap extending through a through hole of the plurality of through holes.

14. A hand tool system comprising:
a first driver comprising a driver handle having a first external configuration and a driver component secured to the driver handle;
a second driver comprising a driver handle having a second external configuration and a driver component secured to the driver handle;
a third driver comprising a driver handle having a third external configuration and a driver component secured to the driver handle;
a driver adapter selectively fittable over the driver handles of the first, second, and third drivers, the driver adapter comprising:
an elongate body having a longitudinal axis, a first end, and a second end spaced longitudinally apart from the first end;
a first socket formed in the first end, the first socket having an internal configuration sized and shaped to receive the driver handle of the first driver, and to transfer torque to the first driver upon rotation of the driver adapter;
a second socket formed in the second end, the second socket having an internal configuration sized and shaped to receive the driver handle of the second driver, and to transfer torque to the second driver upon rotation of the driver adapter;
a third socket formed in the elongate body between the first and second sockets, the third socket having a third configuration sized and shaped to receive a driver handle of a third driver, wherein the third socket extends from the first socket to the second socket so that the third socket is accessible from both the first end and the second end; and
a plurality of through holes formed through and distributed longitudinally along a length of the elongate body between the first end and the second end, the plurality of through holes sized and configured to receive a torque lever that facilitates rotation of the driver adapter.

15. The hand tool system of claim 14 , further comprising a torque lever disposed in a hole of the plurality of through holes.

16. The hand tool system of claim 15 , wherein the torque lever comprises a flexible strap extending through a through hole of the plurality of through holes.

17. The hand tool system of claim 14 , wherein the first external configuration of the driver handle of the first driver has a plurality of flutes, and the internal configuration of the first socket of the driver adapter has a plurality of protrusions configured to extend into the plurality of flutes.

18. The hand tool system of claim 14 , wherein the first external configuration of the driver handle of the first driver has a first plurality of flats, and the internal configuration of the first socket of the driver adapter has a second plurality of flats configured to interface with the first plurality of flats.

19. The hand tool system of claim 14 , wherein the first socket is different in size from the second socket, such that the driver adapter is operable with the first and second drivers having driver handles of different size.

20. The hand tool system of claim 14 , wherein the internal configuration of the first socket is different from the internal configuration of the second socket, such that the driver is operable with the first and second drivers being of different types, and having driver handles of different configuration.

21. A method for configuring a driver adapter, comprising:
forming a first socket in a first end of an elongate body, the first socket having an internal configuration sized and shaped to fit a handle of a first driver and to transfer torque to the first driver upon rotation of the driver adapter;
forming a second socket in a second end of the elongate body, the second end spaced longitudinally from the first end and the second socket having an internal configuration sized and shaped to fit a handle of a second driver; and
