The present invention relates to the field of hand held tools. More specifically, the present invention relates to the field of hexagonal wrenches and related tools and safety, comfort, and convenience of accessories and tools.
Hexagonal wrenches or tool drivers, also referred to as allen wrenches or L-wrenches, have a hexagonal L-shaped body, including a long leg member and a short leg member. The end of either leg member is able to be inserted into a head of a screw or tool designed to accept a hexagonal wrench. Once inserted, rotational pressure is applied to the hexagonal wrench in order to tighten or loosen the screw. The leg members of the hexagonal wrench are designed to be of different lengths in order to allow a user flexibility when using the wrench in different environments and situations. For example, in a narrow, confined environment, the long leg of the hexagonal wrench is inserted into the head of the screw and the user will apply rotational pressure to the short leg. Or, if the environment is not so confined, the user is able to insert the short leg of the hexagonal wrench into the head of the screw and apply rotational pressure to the long leg.
Hexagonal wrenches are manufactured and distributed in multiple English and metric sizes in order to facilitate their use with screw heads of multiple sizes. Such wrenches are usually sold in a set which includes wrenches of multiple sizes but are also distributed individually.
When using a hexagonal wrench, a user, will insert an end of the hexagonal wrench into the head of a workpiece such as a screw, and will then exert rotational pressure on the opposite end of the wrench in order to tighten or loosen the screw. Because of the size and dimensions of the hexagonal wrench it is particularly difficult to exert a great amount of rotational pressure on the hexagonal wrench when the long leg of the hexagonal wrench is inserted into the head of the screw. Because the hexagonal wrench is typically turned with the user's fingers, the user is able to also experience scrapes and cuts from the use of hexagonal wrenches in this manner. Ingenuitive users have also used other tools, including vice grips, pliers and the like, to turn hexagonal wrenches. However, this method is disadvantageous because such tools are able to lose their hold on the hexagonal wrench when rotational pressure is applied or are able to even bend or otherwise disfigure the hexagonal wrench.
A radial foldout tool includes a body with opposing ends and one or more sets of tool drivers. A first set of tool drivers are positioned on/near a first end and a second set of tool drivers are positioned on/near a second end. The tool drivers are contained within channels of the body when in a closed position. The tool drivers are also contained in a plurality of planes. The tool drivers open by rotating/moving in a direction at least perpendicular to a neighboring tool driver. When they are in an open position, each of the tool drivers are in/near the center of the end of the body. By being positioned in/near the center of the end, the radial foldout tool is able to be gripped and turned in a fashion similar to a standard screwdriver.
In one aspect, a device comprises a body having a center, a first end and a second end, wherein the first end and the second end are positioned on opposite ends of the body and a first set of tool drivers positioned within the body in a plurality of planes, wherein each tool driver of the first set of tool drivers is configured to be positioned generally in the center out of the first end in an open position.

A radial foldout tool stores tool drivers in a compact configuration. The tool drivers are able to be positioned for use to tighten or loosen an object such as a screw or bolt.
In some embodiments, each of the tool drivers 112 of the first set of tool drivers 108 are positioned in the body 102 in a different plane from the other tool drivers of the first set of tool drivers 108. Similarly, in some embodiments, each of the tool drivers 112 of the second set of tool drivers 110 are positioned in the body 102 in a different plane from the other tool drivers of the second set of tool drivers 110. For example, in a radial foldout tool 100 which has a body 102 that is generally cylindrical in shape and surface, a first tool driver is positioned at 0 degrees along the circumference of a round first end of the tool, a second tool driver is positioned at 120 degrees along the circumference and a third tool driver is positioned at 240 degrees along the circumference. Tool drivers are similarly positioned on the opposite end as well.
In some embodiments, each tool driver of the first set of tool drivers 108 is positioned in the same plane as a correspondingly positioned tool driver of the second set of tool drivers 110.
In some embodiments, each of the tool drivers of the radial foldout tool 100 is configured to open at least perpendicularly to its neighboring tool driver. For example, with a radial foldout tool 100 containing three tool drivers at each end, a first tool driver opens at 0 degrees, a second tool driver opens at 90 degrees and a third tool driver opens at 270 degrees. This configuration enables each of the tool drivers to open into/near the middle/center of the end, so that a user has better and easier turning power instead of the awkward turning capabilities when the tool drivers are not positioned near the middle of the end.
In some embodiments, a hard stop such as an internal wall prevents the tool drivers from opening past a certain angle such as 180° so that the tool extends perpendicular to the corresponding end.
In some embodiments, the radial foldout tool 100 is designed to include some hexagonal wrenches of English sizes including a 9/32 inch hexagonal wrench, a ¼ inch hexagonal wrench, a 7/32 inch hexagonal wrench, a 3/16 inch hexagonal wrench, a 5/32 inch hexagonal wrench, a 9/64 inch hexagonal wrench, a ⅛ inch hexagonal wrench, a 7/64 inch hexagonal wrench, a 3/32 inch hexagonal wrench and a 5/64 inch hexagonal wrench.
In some embodiments, the radial foldout tool 100 is designed to include some hexagonal wrenches of metric sizes including a 10 mm hexagonal wrench, an 8 mm hexagonal wrench, a 6 mm hexagonal wrench, a 5 mm hexagonal wrench, a 4.5 mm hexagonal wrench, a 4 mm hexagonal wrench, a 3.5 mm hexagonal wrench, a 3 mm hexagonal wrench, a 2.5 mm hexagonal wrench and a 2 mm hexagonal wrench. It should be apparent to one skilled in the art that a radial foldout tool 100 is able to be formed to hold fewer, additional or different sizes of hexagonal wrenches.
In some embodiments, the radial foldout tool 100 is designed to be of a round shape. In some embodiments, the radial foldout tool 100 is designed to be of a triangular shape including three faces, a square or rectangle shape including four faces, a hexagonal shape including six faces or any other appropriate shape. In some embodiments, a single tool driver is positioned on each face of the radial foldout tool 100. In some embodiments, each face is approximately 1 inch across its width and the body 102 of the radial foldout tool 100 is approximately 4.5 inches in length. The body 102 is designed to provide a comfortable, user-friendly interface to a user's hand, in order to enhance a user's ability to exert rotational pressure on the tool driver 112 without subjecting the user to personal injury or requiring the use of additional tools. As should be apparent to one skilled in the art, the body 102 of the present invention may be designed to be of any convenient shape, including any number of faces.
The body 102 of the radial foldout tool 100 is able to be composed of any appropriate material, which is of maximum strength and includes properties which resist materials that the handle will likely be exposed to, e.g., oil, grease, gasoline and the like. In some embodiments, the body 102 is materially composed of 30% glass-filled polycarbonate. In some embodiments, the body 102 is materially composed of any suitable composition including, but not limited to aluminum or steel. In some embodiments, the tool drivers 112 are materially composed of aluminum, steel or any other appropriate material.
In some embodiments, the body 102 is constructed using an injection molded, core/cavity process as is well known in the art. Alternatively, the body 102 may be constructed in any known manner.
To utilize a radial foldout tool, a user moves a desired tool driver from a closed position to an open position. The user moves the desired tool driver using a finger or two to simply pull or push the tool driver in the appropriate direction. In some embodiments, the tool driver locks into place in the open position. The user then grasps the body of the radial foldout tool similarly to grasping a handle of a screwdriver. The user turns the body of the radial foldout tool to either tighten or loosen an object such as a screw or bolt. This turning action is also similar to the use of a screwdriver. Once the user has performed the tightening or loosening actions on the desired object or objects, the tool driver is moved to a closed position by pushing or pulling the tool driver with the user's fingers. In some embodiments, the tool drivers lock in the closed position. When in the closed position, the tools are safely stored within channels in the body to prevent injuries. Unlike a standard screwdriver which has a sharp point jutting out of the handle, the radial foldout tool is able to be compacted and stored safely.
In operation, a radial foldout tool contains multiple tool drivers to consolidate the space needed for a set of tool drivers. Furthermore, the body of the radial foldout tool contains channels for storing the tool drivers in a closed position, so that more tools are able to be stored. The tool drivers are all configured to rotate to an open position which is generally in the middle/center of each end of the body of the radial foldout tool. By being near the middle of each end, turning the radial foldout tool is more stable for a user when the radial foldout tool is in use and each of the tool drivers are in use. The tool drivers are also stored in a plurality of planes in the body which help ensure the tool drivers open to the middle of each end. Since the tool drivers are stored in a plurality of planes, the tool drivers open in a direction at least perpendicular to their neighboring tool driver to further ensure they open to the middle of each end of the radial foldout tool. Previously existing foldout tools suffer from an awkward grasping implementation where the awkwardness is due to the fact that, in the worst case, for example, the previously existing tools allow for the smallest of wrenches to place the part of the tool that is grasped and turned, as far off-axis as possible (and without the benefit of a hard stop in the fully extended position as the present radial foldout tool does). In addition to that, since the previously existing tools are rectangular cubes, the user's hand is required to either fully disengage the tool between turns, or to use rather involved spider-like, alternating stepping actions with the fingers to crawl the hand around the tool into position for the next twist, all the while, keeping the tool stabilized in multiple axes due to the fact that the grasp is compromised and that the wrench, when fully extended, is able to rotate at least 270°. Whereas, with the present radial foldout tool design, the user's hand is able to simply loosen the grasp and slide the palm around within the circumference of the tool while maintaining a steady and sure grasp on the tool, wrench and fastener.
The present invention has been described in terms of specific embodiments incorporating details to facilitate the understanding of principles of construction and operation of the invention. Such reference herein to specific embodiments and details thereof is not intended to limit the scope of the claims appended hereto. It will be readily apparent to one skilled in the art that other various modifications may be made in the embodiment chosen for illustration without departing from the spirit and scope of the invention as defined by the appended claims.
