BACKGROUND OF THE INVENTION

Currently, there is a lack of quality and effective tools that can provide additional length for an open-end wrench. Although there are several existing extension tools are available within the tool industry, each existing extension tool is not able to fully comply with the open-end wrench. For example, even though most of the existing extension tools are able to engage with the open-end wrench, they are not able to fully lock in place with the open-end wrench. As a result, these existing extension tools tend to slip and disengage when force is applied. Additionally, some existing extension tools lack proper surface area for gripping. As a result, the user is not able to fully utilize those extension tools when required. Furthermore, some existing extension tools require intermediary tool components to adequately engage with the open-end wrench. Use of intermediary tool components create a cumbersome assembly and unnecessary failure points within the cumbersome assembly, creating an unsafe work environment for the user.

It is an objective of the present invention to provide an attachment device that effectively and safely engages with an open-end wrench. The present invention is manufactured in the field of mechanics, aircraft, auto, tractor, and any other related tool industry to provide the full scope of a completed device that can effectively and safely engage with the open-end wrench. More specifically, the apex of the present invention provides a secured engagement between the present invention and the open-end wrench. A hilt of the present invention is able to provide proper grip and leverage in order to effectively rotate the open-end wrench.

In reference to FIG. 1, the present invention comprises a hilt 1 and a wrench securing apex 6. The hilt 1 is axially connected to the wrench securing apex 6. The wrench securing apex 6 engages and locks in place with the open-end wrench, and the hilt 1 provides the necessary length and the surface area for the user to grasp the present invention. As a result, the user is able effectively apply pressure to the open-end wrench through the wrench securing apex 6 and the hilt 1. Even though the present invention is described in relation to the open-end wrench, it is to be understood that the present invention can also be used in relation to a close end wrench. Additionally, the present invention is also compatible with a full set of metric wrenches and a full set of standard wrenches.

The hilt 1 is an elongated cylindrical member and is completed with multiple sections to provide multiple functionalities within the present invention. Each of those functionality is explained with respect to the specific section of the cylindrical hilt 1 hereafter. In reference to FIG. 2-3, the cylindrical hilt 1 comprises a pommel end 2, a grip section 3, and an extended length section 4. The pommel end 2, the grip section 3, and the extended length section 4 are axially oriented along a central axis 5 of the hilt 1. As a result, the pommel end 2 is adjacently positioned with the grip section 3. The extended length section 4 is adjacently positioned with the grip section 3, opposite of the pommel end 2. Ergonomic shapes of the pommel end 2 and the grip section 3 allow the user to grasp the present invention with the user's hands. More specifically, the user utilizes one hand to secure the pommel end 2 while the other hand is utilized to secure the grip section 3. The grip section 3 provides sufficient griping surface for the user so that the user can fully grasp the cylindrical hilt 1. The pommel 2 also improves the gripping ability of the cylindrical hilt 1 and guards against slip potential of the user's hand off the cylindrical hilt 1. The length of the extended length section 4 may vary from one embodiment to another in order to increase or decrease the cylindrical hilt arm of the present invention. In other words, the extended length section 4 determines different overall lengths of the present invention as the extended length section 4 functions as the connection cylindrical hilt member between the grip section 3 and the open end wrench securing apex 6.

In reference to FIG. 2, the present invention further comprises a plurality of grooves 13 so that the user is able to apply the required amount of force to the present invention without generating slippage. In other words, the plurality of grooves 13 provides optimal grip ability for the present invention as the plurality of grooves 13 is distributed along the grip section 3. As a result, the user is able to create a stable grip around the grip section 3 during the operation of the present invention. More specifically, the plurality of grooves 13 is traversed into the grip section 3 and radially positioned around the grip section 3. In reference to preferred embodiment of the present invention, the plurality of grooves 13 is centrally positioned with the grip section 3. As a result, the plurality of grooves 13 is able to comfortably and ergonomically position within the palm of the user's hand. In reference to an alternative embodiment of the present invention, the plurality of grooves 13 comprises a first set of grooves and a second set of grooves. The first set of grooves is adjacently positioned with the pommel end 2, and the second set of grooves is adjacently positioned with the extended section 4. As a result, the first set of grooves and the second set of grooves are able to collectively retain the user's hand around the grip section 3 minimizing the slippage within the present invention. Even though the plurality of grooves 13 is separated into the first set of grooves and the second set of grooves within the alternative embodiment, the present invention can include any number of grooves within the grip section 3 as long as the plurality of grooves 13 improves friction between the hilt 1 and the user's hand.
