Abstract

An adjunct device for a speed spanner. The adjunct device is an auxiliary device to facilitate coupling of an L-shape hexagonal spanner to the adaptor of a prime speed spanner. The adjunct device is one-piece in structure, topped by a hollow-set sleeving which protrudes eccentrically downwards to form an assembly mounting. The mounting is flanked by a graded hole which includes a chain of individually sized conterminous hexagonal holes to accommodate engagement by any of a number of differently sized hexagonal spanners, and in such case, the axis on the other side of such any hexagonal spanner will be just aligned to the axis of the sleeving, so that once the sleeving is engaged with the coupling adaptor on the part of the prime speed spanner, the L-shape hexagonal spanner may be readily rotated by manual operation with respect to the prime speed spanner.

Claims

1. An adjunct to a speed spanner, the adjunct adapted as an auxiliary device that can integrally secure differently sized L-shape hexagonal spanners with a prime speed spanner for combined operation, the adjunct comprises:

an upright sleeving, the sleeving including a longitudinal axis, a top surface of said sleeving comprising a polygonal blind hole positioned along the longitudinal axis of the sleeving;

an assembly mounting extending from one side of said sleeving, the mounting comprising a series of graded holes extending substantially perpendicular to the longitudinal axis of said sleeving, the series of graded holes comprising a number of individually sized conterminous hexagonal holes; and

the blind hole of the sleeving adapted to accommodate insertion of a coupling adaptor of a prime speed spanner and the series of graded holes are adapted to receive an L-shape hexagonal spanner of a suitable size, such that an L-shape spanner can be driven by a prime speed spanner.

2. The adjunct to a speed spanner according to claim 1, wherein said sleeving is cylindrical in shape.

3. The adjunct to a speed spanner according to claim 1, wherein said assembly mounting is substantially rectangular in shape.

4. The adjunct to a speed spanner according to claim 1, wherein said series of graded holes are formed by perforation across the assembly mounting.

5. The adjunct to a speed spanner according to claim 1, wherein said series of graded holes accommodate coupling engagement by an L-shape tubular spanner.

6. The adjunct to a speed spanner according to claim 1 or claim 5, further comprising a second assembly mounting that is integrally attached to a bottom of the sleeving.

7. An adjunct to a speed spanner, the adjunct adapted as an auxiliary device that can integrally secure differently sized L-shape hexagonal spanners with a prime speed spanner for combined operation, the adjunct comprises:

an upright sleeving, the sleeving including a longitudinal axis, a top surface of said sleeving comprising a polygonal blind hole positioned along the longitudinal axis of the sleeving;

an assembly mounting extending from one side of said sleeving, the mounting comprising at least two differently sized, sunken, hexagonal coupling holes, with an axial core of each of the coupling holes oriented substantially perpendicular to the longitudinal axis of the sleeving; and

the blind hole of the sleeving adapted to receive a coupling adaptor of a speed spanner and one of the coupling holes is adapted to receive an L-shape hexagonal spanner of a suitable size, such that an L-shape spanner can be driven by a speed spanner.

8. The adjunct to a speed spanner according to claim 7, wherein said sleeving is cylindrical in shape.

9. The adjunct to a speed spanner according to claim 7, wherein said assembly mounting is rectangular in shape.

10. The adjunct to a speed spanner according to claim 7, wherein said coupling holes are formed by perforation across the assembly mounting.

11. The adjunct to a speed spanner according to claim 7, wherein said coupling holes accommodate coupling engagement by an L-shape tubular spanner.

12. The adjunct to a speed spanner according to claim 7 or claim 11, further comprising a second assembly mounting that is integrally attached to a bottom of the sleeving.
