DETAILED DESCRIPTION

[0037] The invention provides for the integration of wrenches and sockets into the handles of hand tools, such as screwdrivers, ratchets, flashlights, axes, utility knives, and hammers, that have a handle section formed by a single piece or body.

[0038] Unlike current wrenches that store a variety of sockets in their handles, the sockets of the present invention do not need to be removed from the handle and inserted into an end piece for use. Instead, the sockets of the present invention are permanently fixed into the body of the handle such that they are usable in place. Similarly, a variety wrenches can be included in the handle section of a tool so that the wrenches are also permanently fixed and usable in place. Advantageously, a member of a socket set or set of wrenches cannot be separated from the handle and misplaced from the other members of the set. It is envisioned that hand tools incorporating handles of the invention are principally used to tighten or loosen relatively smaller sized fasteners rather than fasteners that require powered or large sized tools to generate sufficient torque to either tighten or loosen the fasteners. A variety of exemplary tools having sockets and wrenches fixed in their handles are shown in FIGS. 1-16A.

[0039] As shown in FIGS. 1-12, screwdrivers having handles that include one or more sockets or wrenches can be made in a variety of shapes. For example, FIGS. 1, 2, and 5-8 illustrate handles that are shaped to have six sides, and FIGS. 3, 4, and 9-12 illustrate handles that are shaped to have four sides. Alternative handle shapes and configurations are illustrated in FIGS. 13-16A. FIG. 16B illustrates one configuration from a rear perspective. Those of skill in the art will recognize that multiple handle shapes can be used for a variety of tools. Handles can have more or less sides than those illustrated. That is, a handle can have 3, 4, 5, 6, 7, 8, 9, 10, or more sides. Preferred handles have 3, 4, 5, 6, 7, or 8 sides. The number of sides that a handle can have is limited by the overall size of the handle, as well as, the size(s) of the sockets or wrenches that are to be recessed into the handle.

[0040] Preferably, the handle section has an overall elongated shape, but those of skill in the art will appreciate that the handle section may have an overall ovoid or spherical shape. Sides of the handle section having a socket or wrench recessed into it may have a flattened surface adjacent to the socket or wrench. Alternatively, the area of a side of a handle that is adjacent to a socket or wrench may curve away from the socket or wrench. If the area is curved, then it is curved such that the area does not interfere with the coupling of the socket or wrench to a fastener.

[0041] Herein, a socket is a female recess, indentation, niche, depression, or opening that receives another object, i.e. a fastener, such that together the fastener may be loosened or tightened. Sockets, as well as wrenches, can be in fractional inch (SAE) and metric sizes, and in short (shallow) and longer (deep) varieties.

[0042] Sockets may include convex walls and other similar optimizations to the socket geometry in an effort to minimize the difficulty in working with fasteners that have been stripped or have had their sharp angles rounded. Such sockets allow for the applied torque to be spread away from the corners of fasteners and instead target the thicker, more reinforced areas of a nut or bolt head.

[0043] In some embodiments, handles of the invention include spline sockets that have a ridge in the center of the side wall of the socket and contact the fastener at the approximate midpoint of the side. Such sockets allow increased torque to be applied without damaging the fastener head.

[0044] Several sizes of wrenches and sockets can be made into the handles of screwdrivers and other tools so that each side of the handle has a different size. For example, if the handle is hexagonal, one side can have a wrench or socket size starting at 4 mm or SAE, and each subsequent side being the next size wrench in a set of wrenches or sockets. One handle can then contain a set of 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, and 9 mm or inch, 5/16 inch, inch, 7/16 inch, inch, and 9/16 inch wrenches or sockets. It is recommended that screwdrivers with such handles include either a #1 Phillips-head for metric size wrenches or a #1 slotted screwdriver head for SAE sizes. Alternatively, handles can have larger sized wrenches or sockets, such as 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, and 15 mm or inch, 11/16 inch, inch, 13/16 inch, inch, and 1-inch. It is recommended that screwdrivers with such handles include either a #2 Phillips-head or #2 slotted tip. Larger size handles may only have four sides to accommodate larger size wrenches or sockets such as 16 mm, 17 mm, 18 mm, 19 mm, or larger SAE sizes. It is recommended that screwdrivers with such handles include either a #3 Phillips-head or slotted size tip.

[0045] The handles can be made in any of a variety of ways known in the art. Handles can be made of any suitable material. For example, handles may be made of molded plastics, rubbers, metals, alloys, wood, or any combination thereof. If desired, handles can be made with metal inserts to strengthen their overall structure.

[0046] A socket or wrench may be molded, stamped, or otherwise shaped into a handle by using current manufacturing techniques that are used in the art. The specific choice of manufacture will be influenced by the material used to make a handle, costs, and the number of handles to be made. Those of skill in the art will be aware of other factors that will influence the choice of manufacturing technique.

[0047] Optionally, handles can be removable from the hand tool to allow the use of both ends of a tool simultaneously or to insert a different handle onto a tool. For example, a user may want to interchange metric and SAE handles on a hammer or other hand tool. Similarly, a user may want to interchange Phillips-head (crosshead) and slot (flat) head screwdrivers onto metric and SAE handles of the invention.

[0048] In some embodiments of the invention, handles that are incorporated into screwdrivers can allow for the screwdriver section to retract into the handle for easier storage. Such handles include a hollowed interior suitable for storing the screwdriver section. Those of skill in the art will be familiar with the various types of snapping, locking, or screwing options that are currently available and that are suitable for retracting the screwdriver section into a handle of the invention.
