Patent Application
20170225313
The disclosure relates to tool attachments and more particularly pertains to a new tool attachment for an impact tool.
An embodiment of the disclosure meets the needs presented above by generally comprising a chuck, a shaft and a screw. A first channel is axially positioned in a back face of the chuck. The first channel is right-handedly threaded. The shaft has a first end and a second end. The first end is complementary to the first channel. The second end is hexagonally shaped when viewed longitudinally. The screw is left-handedly threaded. A penetration is axially positioned in the first end of the shaft. The penetration is complementary to the screw. The shaft is threadedly couplable to the first channel and the screw is threadedly couplable to the penetration. The shaft is coupled to the chuck such that the second end is configured to couple the shaft to an impact driver.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A plurality of jaws 36 is positioned in the chuck opening 30. The jaws 36 are operationally coupled to the rotatable section 16. Preferably, the plurality of jaws 36 comprises three jaws 36. The jaws 36 extend and grip upon clockwise rotation of the rotatable section 16 relative to the fixed section 14. The jaws 36 retract and release upon counter-clockwise rotation of the rotatable section 16 relative to the fixed section 14.
The attachment 10 also comprises a first channel 38 and a shaft 40. The first channel 38 is axially positioned in the back face 22 of the chuck 12. The first channel 38 is right-handedly threaded. The shaft 40 has a first end 42 and a second end 44. The first end 42 is complementary to the first channel 38. The second end 44 is hexagonally shaped when viewed longitudinally.
A collar 46 is coupled to and extends radially from the shaft 40 proximate to a midpoint 48 of the shaft 40. The collar 46 defines a threaded segment 50 of the shaft 40 that extends from the first end 42 to the collar 46. The collar 46 also defines a hexagonal segment 52 of the shaft 40 that extends from the second end 44 to the collar 46. An annular grove 54 is positioned in the hexagonal segment 52 of the shaft40. The annular grove 54 is positioned substantially equally distant from the second end 44 and the collar 46. The annular groove 54 is arcuate.
The attachment 10 also comprises a screw 56 that is left-handedly threaded and has a standard head 58. A penetration 60, complementary to the screw 56, is axially positioned in the first end 42 of the shaft 40. The penetration 60 extends from the first end 42 to proximate to the collar 46.
A second channel 62 extends linearly from the first channel 38 to the inner face 24 of the fixed section 14. The second channel 62 is substantially dimensionally equivalent to the penetration 60. A countersink 64 is axially positioned in the inner face 24 of the fixed section 14. The standard head 58 of the screw 56 is positioned in the counter sink 64 when the screw 56 is threadedly positioned in the penetration 60.
In use, the shaft 40 is threadedly couplable to the first channel 38 positioned through the back face 22 of the chuck 12. The shaft is coupled 40 to the chuck 12 such that the second end 44 is configured to couple the shaft 40 to an impact driver. The jaws 36 are configured to reversibly couple to drill accessories. The screw 56 is threadedly couplable to the penetration 60 to prevent decoupling of the shaft 40 from the chuck 12 during reverse operation of the impact driver.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
