[0041] FIG. 1 illustrates a side perspective view of a powered ratchet wrench 100, according to an exemplary embodiment of the present general inventive concept.

[0042] The powered ratchet wrench 100 may be constructed from at least one of metal, plastic, wood, and rubber, etc., but is not limited thereto.

[0043] The powered ratchet wrench 100 may include a handle body 110, a wrench head attachment 120, a motorized assembly 130, a locking pin 140, a sliding lock 150, a light 160, a control unit 170, a power switch 180, and a power source 190, but is not limited thereto.

[0044] The handle body 110 may have a predetermined size based on portability. In other words, the handle body 110 may have a size to facilitate being hand-held. The handle body 110 may facilitate gripping thereof.

[0045] FIG. 2 illustrates a side perspective view of a wrench head attachment 120, according to an exemplary embodiment of the present general inventive concept.

[0046] The wrench head attachment 120 may include a head body 121, a wrench aperture 122, an aperture gear 123, a connecting gear 124, and a pin receiving aperture 125, but is not limited thereto.

[0047] The head body 121 may be removably connected to at least a portion of the handle body 110. More specifically, the head body 121 may be inserted within the handle body 110.

[0048] Referring to FIGS. 1 and 2, the head body 121 is illustrated to have a circular shape. However, the head body 121 may be rectangular, spherical, cylindrical, triangular, pentagonal, hexagonal, heptagonal, octagonal, or any other shape known to one of ordinary skill in the art, but is not limited thereto. As such, the head body 121 may be shaped based on a type of wrench.

[0049] The wrench aperture 122 may also be known as a wrench jaw. The wrench aperture 122 may be disposed on and/or within at least a portion of the head body 121. The wrench aperture 122 may have a shape (e.g., circular, triangular, pentagonal, hexagonal, heptagonal, octagonal) and/or a size (e.g., dimensions) according to a shape and/or a size of a nut and/or a bolt. Accordingly, the wrench aperture 122 may be removably connected to the nut and/or the bolt. In other words, the wrench aperture 122 may receive the nut and/or the bolt therein.

[0050] Furthermore, the wrench aperture 122 may be constructed based on the shape and/or the size of the nut and/or the bolt. Thus, another wrench head attachment 120 may exchange and/or replace the wrench head attachment 120 to be connected to the handle body 110 for a different nut and/or bolt. Therefore, the wrench head attachment 120 facilitates work for a user by eliminating the need to carry multiple wrenches.

[0051] The aperture gear 123 may be circumferentially disposed around a perimeter of the wrench aperture 122 within the head body 121. The wrench aperture 122 may move (i.e., rotate) in response to rotation of the aperture gear 123.

[0052] The connecting gear 124 may be disposed within at least a portion of the head body 121 and/or connected to the aperture gear 123. However, the connecting gear 124 may at least partially protrude from the head body 121 to an exterior environment. The aperture gear 123 may move (i.e., rotate) in response to rotation of the connecting gear 124.

[0053] The pin receiving aperture 125 may be disposed on and/or within at least a portion of the head body 121.

[0054] The motorized assembly 130 may include a power gear 131 and a motor 132, but is not limited thereto.

[0055] The power gear 131 may be disposed within at least a portion of the handle body 110. The power gear 131 may removably connect (i.e. attach) to the connecting gear 124 in response to inserting the head body 121 into the handle body 110.

[0056] The motor 132 may be disposed within at least a portion of the handle body 110 and/or connected to the power gear 131. The power gear 131 may move (i.e., rotate) in response to rotation of the motor 132. Accordingly, the wrench aperture 122 may move in response to rotation of the motor 132 while the power gear 131 is connected to the connecting gear 124.

[0057] The locking pin 140 may be removably connected within the pin receiving aperture 125. The locking pin 140 may prevent the head body 121 from being extracted and/or moving away from the handle body 110 while disposed within the pin receiving aperture 125.

[0058] The sliding lock 150 may be movably (i.e., slidably) disposed on at least a portion of the handle body 110. For example, the sliding lock 150 may engage a clamp within the handle body 110 to tighten around the head body 121 in response to moving to a first position and loosen away from the head body 121 in response to moving to a second position different from the first position. As such, the sliding lock 150 may prevent the head body 121 from moving away from the handle body 110 independent of use of the locking pin 140. Thus, the locking pin 140 and/or the sliding lock 150 may be a fail-safe for each other.

[0059] Accordingly, the head body 121 may be removed from the handle body 110 in response to extracting the locking pin 140 from the pin receiving aperture 125 and/or moving the sliding lock 150 to the second position.

[0060] The light 160 may be disposed on at least a portion of the handle body 110. The light 160 may illuminate a surrounding area of the handle body 110 in response to turning on.

[0061] The control unit 170 may include a first directional button 171 and a second directional button 172, but is not limited thereto.

[0062] The first directional button 171 and/or the second directional button 172 may be disposed on at least a portion of the handle body 110 and/or connected to the motorized assembly 130. Additionally, the first directional button 171 and/or the second directional button 172 may at least partially protrude away from a surface of the handle body 110 to facilitate access to each. The first directional button 171 may move (i.e., rotate) the aperture gear 123 via the motor 132 in a first rotational direction (i.e., clockwise) in response to being depressed. Conversely, the second directional button 172 may move (i.e., rotate) the aperture gear 123 via the motor 132 in a second rotational direction (i.e., counterclockwise) in response to being depressed. As such, the first directional button 171 and/or the second directional button 172 may control a direction of rotation of the aperture gear 123.

[0063] Furthermore, the aperture gear 123 via the motor 132 may increase in rotation speed in response to depressing the first directional button 171 and/or the second directional button 172 harder (e.g., depressed further in the handle body 110). In other words, the further within the handle body 110 the first directional button 171 and/or the second directional button 172 are depressed with respect to an outer surface of the handle body 110, the faster the aperture gear 123 may rotate.

[0064] The power switch 180 may be disposed on at least a portion of the handle body 110. The power switch 180 may turn on the motorized assembly 120, the light 160, and/or the control unit 170 in response to being depressed a first time. Conversely, the power switch 180 may turn off the motorized assembly 120, the light 160, and/or the control unit 170 in response to being depressed a second time.

[0065] Also, the power switch 180 may have multiple settings. For example, the power switch 180 may be moved to a first position to turn on the light only, a second position to turn on the motorized assembly 120, the light 160, and/or the control unit 170, and/or a third position to turn on the motorized assembly 120 and/or the control unit 170 without the light 160.

[0066] The power source 190 may include a battery and a solar cell, but is not limited thereto.

[0067] The power source 190 may be disposed within at least a portion of the handle body 110. The power source 190 may provide power to the motorized assembly 120, the light 160, the control unit 170, and/or the power switch 180.

[0068] Therefore, the powered ratchet wrench 100 may facilitate tightening and/or loosening the bolt and/or the nut without having to require manual movements by the user. Also, the powered ratchet wrench 100 may be customized with different wrench head attachments 120, such that the user does not have to carry multiple wrenches.

[0069] The present general inventive concept may include a powered ratchet wrench 100, including a handle body 110 to facilitate gripping thereof, a wrench head attachment 120 removably connected within at least a portion of the handle body 110, the wrench head attachment 120 including a head body 121, and a wrench aperture 122 disposed on and within at least a portion of the head body 121 to removably connect to at least one of a nut and a bolt, and a control unit 170 disposed on at least a portion of the handle body 110 to move the wrench aperture 122 in a first rotational direction or a second rotational direction opposite to the first rotational direction.

[0070] The wrench head attachment 120 may further include an aperture gear 123 circumferentially disposed around a perimeter of the wrench aperture 122 to move the wrench aperture 122, and a connecting gear 124 disposed within at least a portion of the head body 121 to move the aperture gear 123 in response to being moved.

[0071] The powered ratchet wrench 100 may further include a motorized assembly 130 disposed within at least a portion of the handle body 110 to move the wrench aperture 122.

[0072] The powered ratchet wrench 100 may further include a locking pin 140 removably connected within the head body 121 to prevent the head body 121 from being extracted from the handle body 110 while disposed within the handle body 110.

[0073] The powered ratchet wrench 100 may further include a sliding lock 150 movably disposed on at least a portion of the handle body 110 to prevent the head body 121 from moving away from the handle body 110 in a first position and allow the head body 121 to move away from the handle body 110 in a second position.

[0074] The powered ratchet wrench 100 may further include a light 160 disposed on at least a portion of the handle body 110 to illuminate a surrounding area of the handle body 110.

[0075] The wrench aperture 122 may increase in rotation speed in response to depressing at least one of a first directional button 171 and a second directional button 172 of the control unit 170 further within the handle body 110 with respect to an outer surface of the handle body 110.

[0076] Although a few embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
