Abstract

A double-sided, detachable tool includes a first tool half and a second tool half. The first tool half has a first tool head on a first end, a first stepped profile on a bottom surface, and a latch protruding from the bottom surface. The second tool half has a second tool head on its first end, a second stepped profile on its bottom surface, and a latching aperture extending through the second tool half from its top side to the bottom side. The latch is inserted into the latching aperture to connect the first tool half to the second tool half and is removed from the latching aperture to detach the first tool half from the second tool half. The transitions from the stepped profiles to the seconds ends of the tool halves create a substantially flush surface therebetween.

First claim

What is claimed is:

1. A double-sided, detachable tool comprising:
a first tool half having a first end, a second end opposite the first end, a top surface, and a bottom surface opposite the top surface, the first tool half comprising:
a first tool head disposed at the first end of the first tool half,
a first stepped profile disposed on the bottom surface of the first tool half, and
a latch disposed on the bottom surface of the first tool half; and

a second tool half having a first end, a second end opposite the first end, a top surface, and a bottom surface opposite the top surface, the second tool half comprising
a second tool head disposed at the first end of the second tool half,
a second stepped profile disposed on the bottom surface of the second tool half, and
a latching aperture extending through the second tool half from the top side to the bottom side;

the latch being inserted into the latching aperture to connect the first tool half to the second tool half and being removed from the latching aperture to detach the first tool half from the second tool half; and
when connected, the second end of the first tool half being adjacent to the second stepped profile of the second tool half, wherein the top surface of the first tool half is substantially flush with the second stepped profile of the second tool half, and the second end of the second tool half being adjacent to the first stepped profile of the first tool half, wherein the top surface of the second tool half is substantially flush with the first stepped profile of the first tool half.

2. The double-sided, detachable tool of claim 1 , wherein the latching aperture comprises a counterbored, flanged profile, the flanged profile comprising a large annular profile, a small annular profile, and a slot extending between the large annular profile and the small annular profile; wherein the latch comprises an annular flange disposed on a keyed extension comprising two parallel flat surfaces, and wherein the annular flange is configured to fit into the large annular profile and the two parallel flat surfaces are configured to fit into the slot.

3. The double-sided, detachable tool of claim 2 , wherein when the first tool half is connected to the second tool half, a top of the annular flange is substantially flush with the top surface of the second tool half.

4. The double-sided, detachable tool of claim 2 , wherein the two parallel flat surfaces only fit into the slot when the first tool half is substantially perpendicular to the second tool half.

5. The double-sided, detachable tool of claim 1 , wherein the first stepped profile of the first tool half comprises a z-shaped profile, and the second end of the second tool half is formed in a corresponding z-shaped profile to the z-shaped profile of the first tool half.

6. The double-sided, detachable tool of claim 1 , wherein the first tool head disposed on the first end of the first tool half comprises a first opening having a first size and a second opening having a second size.

7. The double sided, detachable tool of claim 6 , wherein the second tool head disposed on the first end of the second tool half comprises a multi-point box head.

8. The double-sided, detachable tool of claim 6 , wherein the second tool head disposed on the second end of the second tool half comprises a third opening having the second size.

9. The double-sided, detachable tool of claim 1 , wherein the first tool half comprises a catch rod disposed at the second end of the first tool half, the catch rod being biased outward from the second end of the first tool half, wherein the second stepped profile of the second tool half comprises a u-shaped slot, and wherein the catch rod is biased into the u-shaped slot when the first tool half is connected to the second tool half.

10. The double-sided, detachable tool of claim 9 , wherein the first tool half comprises a catch release switch connected to the catch rod, the catch release switch being operable to move the catch rod out of the u-shaped slot and into the second end of the first tool half enabling relative rotation between the first tool half and the second tool half.

11. A double sided, detachable tool comprising:
a first tool half having a first end, a second end opposite the first end, a top surface, and a bottom surface opposite the top surface, the first tool half comprising:
a first tool head disposed at the first end of the first tool half,
a first stepped profile disposed on the bottom surface of the first tool half, the first stepped profile being formed in a z-shape, and
a latch disposed on the bottom surface of the first tool half; and

a second tool half having a first end, a second end opposite the first end, a top surface, and a bottom surface opposite the top surface, the second tool half comprising
a second tool head disposed at the first end of the second tool half,
a second stepped profile disposed on the bottom surface of the second tool half, and
a latching aperture extending through the second tool half from the top side to the bottom side;

the latch being inserted into the latching aperture to connect the first tool half to the second tool half and being removed from the latching aperture to detach the first tool half from the second tool half;
the second end of the second tool half being formed in a corresponding z-shaped profile to the first stepped profile, the corresponding z-shaped profile being adjacent to the first stepped profile when the first tool half is connected to the second tool half.

12. The double-sided, detachable tool of claim 11 , wherein when the first tool half is connected to the second tool half, the second end of the first tool half is adjacent to the second stepped profile of the second tool half, the top surface of the first tool half being substantially flush with the second stepped profile of the second tool half, and the top surface of the second tool half being substantially flush with the first stepped profile of the first tool half.

13. The double-sided, detachable tool of claim 11 , wherein the latching aperture comprises a counterbored, flanged profile, the flanged profile comprising a large annular profile, a small annular profile, and a slot extending between the large annular profile and the small annular profile; wherein the latch comprises an annular flange disposed on a keyed extension comprising two parallel flat surfaces, and wherein the annular flange is configured to fit into the large annular profile and the two parallel flat surfaces are configured to fit into the slot.

14. The double-sided, detachable tool of claim 13 , wherein when the first tool half is connected to the second tool half, a top of the annular flange is substantially flush with the top surface of the second tool half.

15. The double-sided, detachable tool of claim 13 , wherein the two parallel flat surfaces only fit into the slot when the first tool half is substantially perpendicular to the second tool half.

16. A double sided, detachable tool comprising:
a first tool half having a first end, a second end opposite the first end, a top surface, and a bottom surface opposite the top surface, the first tool half comprising:
a first tool head disposed at the first end of the first tool half,
a first stepped profile disposed on the bottom surface of the first tool half,
a latch disposed on the bottom surface of the first tool half, and
a catch rod disposed at the second end of the first tool half, the catch rod being biased outward from the second end of the first tool half; and

a second tool half having a first
