Ratchet wrench drill attachment

Abstract

A ratchet wrench drill attachment including a housing assembly, a gear assembly, and a drill assembly is disclosed. These assemblies in conjunction with one another provide a simple solution to automating a ratchet wrench. The ratchet wrench includes a drill attachment. The actuation of the drill causes the rotation of a shaft that includes a perpendicular gear mounted thereon. The flat circular perpendicular gear engages simultaneously with a top gear and a bottom gear housed within an annular portion of the housing assembly. The top gear includes an interior portion that receives a removeable socket. The removable socket can be hexagonal or square to engage with fasteners. Thereby enabling the user to loosen or tighten said fasteners automatically.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

(7) Referring now to the drawings, where the present invention is generally referred to with numeral 10, it can be observed that it basically includes a housing assembly 20, a gear assembly 40, a drill assembly 60, a fastener assembly 70, and a case assembly 80.

(8) Best shown in FIGS. 1-3 housing assembly 20 may include a housing 22. The housing 22 may be tubular and encase a portion of the rotating shaft 44. It may be suitable for the housing 22 to allow for the free rotation of the rotating shaft 44 therein. The housing 22 may include an angled distal end that tapers outward with respect to the tubular portion of said housing 22. The housing 22 including an annular portion 24 located at the angled distal end. The annular portion 24 may be a circular member that serves as a mounting point for a removable socket 46. In alternate embodiments the removable socket 46 may house the top gear 41 or bottom gear 42. The removable socket 46 including a ratchet yoke 48. The ratchet yoke 48 may be a circular opening that includes an interior portion with ridges. Said interior portion of the ratchet yoke 48 may engage with the outer perimeter of a fastener 72 of the fastener assembly 70. It may be suitable for the fastener 72 to include a hexagon nut, a square nut, a plate nut, a pipe nut, hex bolts, bolts, or any variation thereof. It may be preferable for the ratchet yoke 48 to rotate perpendicularly with respect to the rotating shaft 44. The ratchet yoke 48 may be entirely within the perimeter of the annular portion 24. It may be preferable for the housing 22 and annular portion 24 to be made out of a metallic material for durability.

(9) Best illustrated in FIGS. 3 and 4 gear assembly 40 may include a top gear 41. The top gear 41 may be located within a removeable socket 46 and mounted within a top end of the annular portion 24. The removeable socket 46 may also be mounted within a bottom end of the annular portion 24. It may be suitable for top gear 41 to surround a ratchet yoke 48. The top gear 41 may include squared gear teeth. Wherein the squared gear teeth of the top gear 41 may extend downwardly to engage with a perpendicular gear 43. In one embodiment the perpendicular gear 43 may be a flat circular gear mounted with a flat side in constant abutment to a flat distal end of the rotating shaft 44. The perpendicular gear 43 may include gear teeth that extend outwardly about its outer edge. The rotating shaft 44 may include a hexagonal exterior shape. The perpendicular gear 43 may convert the rotation of the rotating shaft 44 into the rotation of the top gear 41. The bottom gear 42 may be annular with the same exterior circumference as the top gear 41. The bottom gear 42 and top gear 41 may rotate in opposite directions when the rotating shaft 44 is actuated by the drill 62. The exterior of the bottom gear 42 may include opposingly mounted bottom gear teeth with respect to the top gear teeth of the top gear 41. The bottom gear 42 may provide bottom support to the perpendicular gear 43 to allow for the smoother rotational motion of the top gear 41. It may be suitable for the perpendicular gear 43 to rotate the bottom gear 42 and the top gear 41 in opposing directions. The top gear 41 and bottom gear 42 may be entirely nestled within the annular portion 24 of the housing assembly 20. In an alternate embodiment the gear teeth of each of the top gear 41 and the bottom gear 42 may be triangular.

(10) As shown in FIG. 1 drill assembly 60 may include a drill 62. It may be preferable for the drill 62 to engage the rotating shaft 44 via a drill attachment 45. The drill attachment 45 may be configured to be mounted to a drill 62 with quick attachment capabilities. The rotational power of the drill 62 may linearly correlate to the torque exhibited by the perpendicular gear 43. The drill 62 may allow for the clockwise and counterclockwise rotation of the drill attachment 45 and by extension the perpendicular gear 43 located at the end of the rotating shaft 44. As the perpendicular gear 43 rotates it may engage with the bottom gear 42. The bottom gear 42 may provide bottom support to the perpendicular gear 43 and rotate in the opposite direction as the top gear 41. Thereby also causing the ratchet yoke 48 located on the interior of the removeable socket 46 located on the top end and the bottom end of the annular portion 24 to rotate perpendicularly with respect to the rotating shaft 44. The annular portion 24 of the housing assembly 20 may serve as an enclosure to ensure the perpendicular gear 43 simultaneously engages the top gear 41 and the bottom gear 42. The ratchet yoke 48 may include ridges or protrusions that engage the exterior of a fastener 72. Thereby enabling the user to tighten or loosen said fastener.

(11) Shown in FIG. 5 it may be suitable for case assembly 80 to include case 82. Wherein the case 82 may allow for the storage of multiple removeable sockets 46 as well are the present invention 10. The removeable sockets 46 may include ratchet yokes 48 of varying diameters that can engage with fasteners 72 of different sizes.
