[0029]
[0030] The pair of protrusions 40, 42 may extend outwardly from each arcuate surface 20. Each of the pair of protrusions 40, 42 may include a curved surface. The pair of protrusions 40, 42, may combine to form a second arcuate surface 44 between the pair of protrusions 40, 42. The second arcuate surface 44 may include a greater parabolic angle relative to the first arcuate surface 20. The second arcuate surface 44 may provide a surface configured to receive the finger of the user. The pair of protrusions 40, 42 extending from each arcuate surface 20 may include one or more fillet edge. The user with at least four fingers in contact with the second arcuate surface 44 may provide force to one of the pair of protrusions 40, 42 to provide torque to perform a specific task.
[0031] As shown in
[0032] Each prong 10 may be co-planar on a plane perpendicular with the central axis A1. For example, each prong 10 may extend along an axis P comprising about a 72 degree angle relative to each other prong 10. In another example, each prong 10 may be disposed at about a 90 degree angle relative to one another to substantially resemble a plus-sign shape. For example, one or more of the prongs 10 may be disposed at about a 90 degree angle, i.e. each prong may comprise an angle within ten degrees of 90 degrees. In another embodiment, each of the prongs 10 extend along an axis P comprising varied angles relative to each adjacent angle to resemble the general anatomical position of many user's fingers. For example, each angle P between each of the prongs 10 may vary between 60 and 120 degrees.
[0033] Each prong 10 may be substantially straight and comprise a uniform width. In another embodiment, each prong 10 may comprise a variable width. For example, the width of each prong 10 may decrease as each prong 10 extends a greater distance from the central point C.
[0034]
[0035] In one embodiment, the handle 100 may be configured to engage to an end of the hand tool 50 to comprise a unitary hand tool piece. In another embodiment, the handle 100 may be removably engaged to the hand tool 50. One of multiple handles 100 comprising components as described herein may be removably engaged to the hand tool 50.
[0036] The handle 100 may connect to the hand tool 50 using the connection member 30. In an embodiment, the connection member 30 is sized to appropriately engage within a space 52 formed in the hand tool 50, so that the connection member 30 may frictionally engage with the hand tool 50.
[0037] In one embodiment, the connection member 30 is hollow. As shown in

The locking mechanism 36 may extend into the connection member 30 to frictionally engage the connection member 30 to prevent the connection member 30 from being removed from the hand tool 50. In one embodiment, the locking mechanism 36 may include a lock that may slide between a locked position and an unlocked position. The locked position may bias the connection member 30 within the hand tool 50 to prevent the connection member 30 from being removed from the hand tool 50.
[0039] In operation, the user may place their hand above the handle 100. At least four fingers of the user may contact each of the arcuate surfaces 20. In some embodiments, each of the at least four fingers may be disposed on each of the at least four second arcuate surfaces 44 formed between the pair of protrusions 40, 42 disposed on each arcuate surface 20. When the hand is placed on the handle 100, the wrist of the user may be substantially straight to avoid discomfort from the wrist of the user bending. The palm of the user may rest above the handle 100 or rest on a top surface 12 of the handle 100.
[0040] When the fingers of the user are received by the arcuate surfaces 20 of the handle 100, the user may provide torque onto the handle 100 directed around the central axis A1. The user may turn the handle 100 to perform a task, such as drive a screw into a material. The length of the prongs 10 of the handle 100 may allow for a greater mechanical advantage when rotating the handle 100, which may allow for greater force applied to the active component 56 of the hand tool 50 with a certain amount of torque provided. This may allow for less overall rotational torque to be applied to the handle 100 to provide sufficient force to perform a task, such as drive a screw into a material.
