[0040] The present disclosure provides a tool which enables the user to tighten and loosen a fastener, nut or bolt from a central point where a toolhead rests between two handle portions, for example the center of the wrench shaft, while holding the ends of the handle portions with both hands for more power and leverage during turning.

[0041] The tool does not necessarily have to be a wrench and could also be implemented as a screwdriver or hammered tool. If the tool is a wrench, any combination of different wrench heads may be used between the central toolhead and toolheads on the opposing ends of the handle portions, including having no toolheads on the opposing ends of the handle portions.

[0042] Various example configurations are illustrated and described that are meant solely as illustrative examples and are not limiting. Other configurations and modifications not explicitly described herein could also be included in conjunction with the tool of the present disclosure as described and illustrated by way of the examples herein.

[0043] Referring to FIGS. 1-3, various views of an example configuration of a wrench 100 according to the present disclosure are shown.

[0044] In the illustrated configuration, the wrench has a closed-ended wrench head 103 disposed at the center between two handle portions 107, and with an open-ended wrench head 101 and a second closed-ended wrench head 105 at the opposing distal ends of the wrench.

[0045] An alternative configuration of the disclosed wrench 100 is shown in FIGS. 4A-C. Referring more specifically to FIG. 4A, the wrench 100 has an open-ended wrench head 101 disposed between first and second handle portions 109A, which are at a 60 degree angle to one another. The first and second handle portions 109A are generally formed of one piece of material. In FIG. 4B, the wrench 100 is illustrated with the open-ended wrench head 101 positioned on top of V-shaped first and second handle portions 109B. In FIG. 4C, another wrench 104 is illustrated with central, open-ended, detachable, and interchangeable wrench heads 111A-D configured to be positioned on top of the V-shaped first and second handle portions 109B and having variant sizes.

[0046] FIGS. 5A-C show similar configurations to FIGS. 4A-C, respectively, but the wrench 200 comprises a closed-ended wrench head 201 as the central toolhead disposed between the two handle portions 109A. In FIG. 5B, the wrench 200 is illustrated with the closed wrench head 201 positioned on top of V-shaped first and second handle portions 109B. In FIG. 5C, another wrench 204 is illustrated with central, closed, detachable, and interchangeable wrench heads 211A-D configured to be positioned on top of the V-shaped first and second handle portions 109B and having variant sizes.

[0047] Referring to FIG. 6 another alternative example configuration is shown with a wrench 300 having a central open-ended wrench head 305 extending from the joint of the two handle portions 301.

[0048] An open-ended wrench head 303 and a closed-ended wrench head 307 are disposed at either end of the straight handle portions 301.

[0049] As shown in FIG. 7, the tool can also comprise a wrench 400 with an adjustable open-ended central wrench head 401 disposed between the two handle 103.

[0050] Furthermore, in some configurations, the handle portions 103 themselves may be adjustable as shown in FIGS. 8-10 where another example configuration is shown in the form of a wrench 500 having an adjustable open-ended wrench head 401 disposed between first and second handle portions 103, but with the handle portions 103 being rotatably adjustable so as to be able to change the angle between them like a pair of scissors.

[0051] In this configuration, the first and second handle portions are joined together by a flexible joint.

[0052] Referring to FIG. 8, the configuration of FIGS. 8-10 may have the handle portions completely together in position 500A. The handle portions then effectively act as a single wider handle.

[0053] Referring to FIG. 9, the configuration of FIGS. 8-10 may have the handle portions partially open in position 500B or any angle between 0 and 180 degrees. This flexibility can be very useful when working in tight spaces.

[0054] Referring to FIG. 10, the configuration of FIGS. 8-10 may have the handle portions completely apart as in position 500C to form a long handle shaft with the wrench head 401 at the center. This allows for maximum torque to be applied.

[0055] Although not illustrated, the central toolhead may also be slidable along the handle portions to bias it away from the center of the wrench shaft, the handle portions may be detachable from the central toolhead so that different handle portions appropriate for the job at hand can be interchangeably affixed to the tool, and the handle portions may even be retractable to provide increased versatility.

[0056] Referring to FIG. 11, another example configuration of a wrench 600 having a similar configuration to that of FIGS. 1-3 is shown, with an open ended wrench head 601 and a closed ended wrench head 603 disposed at either end of the handle portions which from a straight shaft, but also with the central wrench head 607 protruding perpendicularly to the plane of the handle portions similarly to a nut driver wrench head so that when the central wrench head is placed on a nut, the wrench will be raised or elevated so the user will have room to fit his fingers underneath the wrench when he holds it with both hands. Otherwise, the wrench might lay flush on a base surface that the fastener is located on, preventing a user from properly gripping the handle portions.

[0057] The wrench head, both the central head and the head at either end of the handle portions, can be any one of the following non-exhaustive list: a pipe wrench head, chain wrench head, socket wrench head, torque wrench head, ratcheting wrench head, oil filter wrench head, combination wrench head, open-ended wrench head, closed-ended wrench head, crowfoot wrench head, pedal wrench head, monkey wrench head, pliers wrench head, strap wrench head, plumber's wrench head, tap wrench head, spud wrench head, alligator wrench head, basin wrench head, armorer's wrench head, dog bone wrench head, drum key wrench head, bung wrench head, fan clutch wrench head, hammer wrench head, torx key wrench head, cone wrench head, garbage disposal wrench head, tension wrench head, spoke wrench head, spanner wrench head, nut driver wrench head, box end wrench head, flare nut wrench head, allen wrench head, bristol wrench head, ratcheting box wrench head, flex wrench head, socket ratchet wrench head, lug wrench head, and spark plug wrench head.

[0058] If the wrench head is a socket head type, it can have 12 any socket geometry, including but not limited to: flank drive, spline drive, 10-pointed drive, 12-pointed drive.

[0059] Referring now to FIGS. 12A-B, isometric views of other example configurations of a tool according to the present disclosure are illustrated in the form of, with respect to FIG. 12A, a wrench 700 with a fixed, central, socket head 701 disposed between first and second V-shaped handle portions 703. In FIG. 12B, the wrench 700 is illustrated with detachable, interchangeable, and central socket heads 705A-D positioned on the V-shaped first and second handle portions 703 with interchangeable connectivity and an array of socket sizes.

[0060] FIG. 13 illustrates an isometric view of a lug wrench 800 with V-shaped first and second handle portions 801 applied to a lug nut 803 on the wheel 805 of a vehicle (not shown).

[0061] FIG. 14 illustrates an isometric view of another example configuration of a tool 900 according to the present disclosure having a pipe wrench head 901 positioned on top of V-shaped first and second handle portions 903.
