BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The subject matter which is regarded as the invention is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification, The foregoing and other objects, features, and advantages of the invention are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:

[0022] FIG. 1 is a top perspective view of a J-Hook Device in accordance with the present invention;

[0023] FIG. 2 is a side view thereof;

[0024] FIG. 3 is a top view thereof;

[0025] FIG. 4 is a rear view thereof:

[0026] FIG. 5 is an illustration of a SDS shank in accordance with the present invention; and

[0027] FIG. 6 is an illustration showing preferred. relative dimensions.

DETAILED DESCRIPTION

[0028] The following brief definition of terms shall apply throughout the application;

[0029] The term “comprising” means including but not limited to, and should be interpreted in the manner it is typically used in the patent context;

[0030] The phrases “in one embodiment,” “according to one embodiment,” and the like generally mean that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present invention, and may be included in more than one embodiment of the present invention (importantly, such phrases do not necessarily refer to the same embodiment);

[0031] If the specification describes something as “exemplary” or an “example,” it should be understood that refers to a non-exclusive example; and

[0032] If the specification states a component or feature “may,” “can,” “could,” “should,” “preferably,” “possibly,” “typically,” “optionally,” “for example,” or “might” for other such language) be included or have a characteristic, that particular component or feature is not required to be included or to have the characteristic.

[0033] Referring now to FIG. 1-8 of the drawings, there is shown views of the J-Hook Device in accordance with the present invention.

[0034] As used herein, the terms “top”, “bottom”, “front”, “rear”, etc. refer to the wire untwisting device of the present invention in the orientation shown in FIG. 1-8, It will be appreciated, however, that the device will assume any of various orientations when in use. It will also be recognized that although the device is described in terms of the untwisting of multi-wire electrical cable, it can also be used to untwist various other multi-strand objects, including. rope. In addition, it is also possible to use the inventive device to twist multi-strand objects such as electrical cable or rope.

[0035] In use, the ends of a multi-wire cable, such as one containing from about 12 to about 20 wires, is partially twisted around knurled section 12. It will be appreciated that knurled section 12 provides a gripping surface for holding the ends of the multi-wire cable. The J-hook device 10 is rotated, through rotation of shaft 13, and thereby untwist the length of wire cable. The knurled section 12 may be any suitable knurled pattern, or reticulated pattern, such as, for example, a 60 deg. diamond pattern knurl.

[0036] It will be appreciated that hook device 10 may be any suitable metal material such as, for example, stainless steel, low carbon steel, high speed steel (HSS), any suitable steel alloy (e.g., Cobalt). It will also be appreciated that hook device 10 may be any suitable hook device 10 may be any suitable material hook device 10 may be any suitable polymer material such as, for example, non-conducting plastic, carbon fiber reinforced polymer, polystyrene, and/or polycarbonate.

[0037] In this manner, untwisting of lengths of multi-wire electrical cable can be accomplished in a significantly reduced time as compared to the currently performed manual untwisting of the wire strands.

[0038] Shaft 13 can also comprise a drill bit shank 14 which is shaped so as to permit J-hook device 10 to securely mate with a drill or other device to facilitate the mechanical rotation of J-hook device 10. It will be appreciated that the drill bit shank 21 may be any suitable shank such as, for example, a 3-flat shank, a reduced shank, a brace shank, a straight shank, a hex shank, a SDS shank (FIG. 5-61), a triangular shank, a Morse taper shank, a square shank, a traded shank, or a tang shank. FIG. 4 shows a rear view 41 of shank 14. It will also be appreciated that shank 21 and shank 14 may be separated by groove 22 to facilitate fitment within an impact drill chuck.

[0039] Referring also to FIG. 6 there is shown illustration showing preferred relative dimensions of J-hook device 10. The center line 52 of J-hook device 10 bisects the arc 12A of the knurled section 12. It will he appreciated this feature provides stability and minimizes wobble when the J-hook device 10 is rotated at high speeds.

[0040] Still referring to FIG. 6, the knurled section 12 includes three zones, 121, 122, and 123. Zones 121 and 122 are straight knurled zones and each straight zone comprises 14.5 units in length. Zone 123 is an arc zone disposed between zones 121 and 122. The outer cord length of arc zone 123 is 28 units. It will be understood that the relative units of section 12 work cooperatively to efficiently and safely twist and/or untwist wire in accordance with the present invention, The knurled section 12 safely grips a wire bundle to be twisted or untwisted.

[0041] It should be understood that the foregoing description is only illustrative of the invention. Thus various alternatives and modifications can be devised by those skilled in the art without departing from the invention Accordingly, the present invention is intended to embrace all such alternatives, modifications and variances that fall within the scope of the appended claims.
