Abstract
A screw bit body which allows for efficient torque force application onto a socket fastener. The screw bit body includes a plurality of laterally-bracing sidewalls, a first base, and a second base. The laterally-bracing sidewalls are radially distributed about a rotation axis of the screw bit body with each further including a first lateral edge, a second lateral edge, a bracing surface, and an engagement cavity. The engagement cavity creates an additional gripping point to prevent slippage in between the screw bit body and the socket fastener. The engagement cavity traverses normal and into the bracing surface. Additionally, the engagement cavity traverses into the screw bit body from the first base to the second base. The engagement cavity is specifically positioned offset from the first lateral edge by a first distance and positioned offset from the second lateral edge by a second distance.
Description
Multi-Grip Socket Bit FIELD OF THE INVENTION
The present invention generally relates to various tools designed for tightening or loosening fasteners, in particular bolts and nuts. More specifically, the present invention is an anti-slip multidirectional driver bit, designed to prevent damaging or stripping fasteners during the extraction or tightening process.
BACKGROUND OF THE INVENTION
Hex bolts, nuts, screws, and other similar threaded devices are used to secure and hold multiple components together by being engaged to a complimentary thread, known as a female thread. The general structure of these types of fasteners is a cylindrical shaft with an external thread and a head at one end of the shaft. The external thread engages a complimentary female thread tapped into a hole or a nut and secures the fastener in place, fastening the associated components together. The head receives an external torque force and is the means by which the fastener is turned, or driven, into the female threading. The head is shaped specifically to allow an external tool like a wrench to apply a torque to the fastener in order to rotate the fastener and engage the complimentary female threading to a certain degree. This type of fastener is simple, extremely effective, cheap, and highly popular in modern construction.
One of the most common problems in using these types of fasteners, whether male or female, is the tool slipping in the head portion, or slipping on the head portion.
This is generally caused by either a worn fastener or tool, corrosion, overtightening, or damage to the head portion of the fastener. The present invention is a driving bit design that virtually eliminates slippage. The design uses a series of segmented portions that bite into the head of the fastener and allow for efficient torque transfer between the driving bit and the head portion of the fastener. The present invention eliminates the need for the common bolt extractors as they require unnecessary drilling and tools. With the development of electric screwdrivers, and drills, people have been using, power tools to apply the required torsional forces and remove various fasteners. The present invention provides a double-sided driver end bit, thus allowing for torque to applied to the fastener in both clockwise and counterclockwise directions, thus tightening or loosening the fastener. Most driver end bits have a standardized one fourth inch hex holder, and come in various configurations including but not limited to, square end, hex end, or star end.
SUMMARY OF THE INVENTION
In one aspect, there is provided a multi-grip socket bit comprising: at least one screw bit body; the at least one screw bit body comprising a plurality of laterally-bracing sidewalls, a first base and a second base; each of the plurality of laterally-bracing sidewalls comprising a first lateral edge, a second lateral edge, a bracing surface and an engagement cavity; the plurality of laterally-bracing sidewalls being radially positioned about a rotation axis of the at least one screw bit body; the first lateral edge and the second lateral edge being positioned opposite to each other across the bracing surface;
the engagement cavity extending normal and into the bracing surface; the engagement cavity extending into the at least one screw bit body from the first base towards the second base; the engagement cavity being positioned offset from the first lateral edge by a first distance; the engagement cavity being positioned offset from the second lateral edge by a second distance, wherein the first distance is greater than or less than the second distance; the first lateral edge and the second lateral edge each being a corner;
an entire cross-section of the engagement cavity being parallel to the first base and the second base; the engagement cavity being concave along a direction from the first lateral edge to the second lateral edge; the first base comprising a first base surface;
the first base surface and the bracing surface each being flat; and the first base surface and the bracing surface being oriented perpendicular to each other.

The present invention is a socket bit that is compatible with a variety of torque tools including, but not limited to, traditional drills, bit-receiving screwdrivers, socket wrenches, and socket drivers.
In its simplest embodiment, referring to FIG. 1, the present invention comprises an at least one screw bit body 1. The screw bit body 1 is a shank which engages the socket fastener, such as a socket screw or a socket bolt, in order to apply a torque force onto the socket faster. The screw bit body 1 comprises a plurality of laterally-bracing sidewalls 2, a first base 9, and a second base 10. In general, the screw bit body 1 is a prism composed of a strong metal. Each of the plurality of laterally-bracing sidewalls 2 engage within and grip the socket fastener in order to efficiently transfer torque from a
3 torque tool to the socket fastener. The first base 9 and the second base 10 are positioned opposite to each other along the plurality of laterally-bracing sidewalls 2.
Additionally, the first base 9 and the second base 10 are oriented perpendicular to each of the laterally-bracing sidewalls and thus enclose/complete the prism shape of the screw bit body 1.
Referring to FIG. 3 and FIG. 4, each of the laterally-bracing sidewalls comprises a first lateral edge 3, a second lateral edge 4, a bracing surface 5, and an at least one engagement cavity 6. The plurality of laterally-bracing sidewalls 2 is radially positioned about a rotation axis 11 of the screw bit body 1 in order to yield a geometric profile complimentary to that of the socket fastener. The number within the plurality of laterally-bracing sidewalls 2 is subject to change to compliment the shape and profile of a variety of socket fasteners. In one embodiment of the present invention, the number within the plurality of laterally-bracing sidewalls 2 is six and the resulting geometric profile of the screw bit body 1 is a hexagon. In an alternative embodiment of the present invention, the number within the plurality of laterally-bracing sidewall is four and the resulting .. geometric profile of the screw bit body 1 is a square.
The bracing surface 5 physically presses against the socket fastener, in particular the lateral sidewall of a head portion from the socket fastener. The first lateral edge 3 and the second lateral edge 4 are positioned opposite to each other across the bracing surface 5. When viewed from either the top perspective or the bottom perspective, the first lateral edge 3 and the second lateral edge 4 from each of the plurality of laterally-bracing sidewalls 2 make up the corners of the screw bit body 1. The engagement cavity traverses normal and into the bracing surface 5 and creates an additional gripping point/tooth on the bracing surface 5. This gripping point is created with the engagement cavity 6 and an adjacent edge, wherein the adjacent edge is either the first lateral edge 3 .. or the second lateral edge 4; in particular, the adjacent edge is the edge closest to the engagement cavity 6. Additionally, the engagement cavity 6 traverses into the screw bit body 1 from the first base 9 towards the second base 10. The engagement cavity 6 also tapers from the first base 9 to the second base 10. This ensures that the additional gripping point extends along the length of the screw bit body 1 for maximum grip engagement between the screw bit body 1 and the socket fastener. Furthermore, it is preferred that a cross-section 7 of the engagement cavity 6 is a semi-circular profile. The

The engagement cavity traverses normal and into the bracing surface 5 and creates an additional gripping point/tooth on the bracing surface 5. This gripping point is created with the engagement cavity 6 and an adjacent edge, wherein the adjacent edge is either the first lateral edge 3 .. or the second lateral edge 4; in particular, the adjacent edge is the edge closest to the engagement cavity 6. Additionally, the engagement cavity 6 traverses into the screw bit body 1 from the first base 9 towards the second base 10. The engagement cavity 6 also tapers from the first base 9 to the second base 10. This ensures that the additional gripping point extends along the length of the screw bit body 1 for maximum grip engagement between the screw bit body 1 and the socket fastener. Furthermore, it is preferred that a cross-section 7 of the engagement cavity 6 is a semi-circular profile. The
4 semi-circular profile ensures that there are little to no high stress points in the screw bit body 1, thus increasing the overall longevity of the tool. Alternative profiles may be used for the engagement cavity 6 including, but not limited to, a semi-square profile, a semi-rectangular profile, and a semi-oval profile.

The second screw bit body 17 is designed to unscrew/extract the socket fastener, i.e. the counter-clockwise version.
Referring to FIG.
4, the first distance 12 of the second screw bit body 17 is greater than the second distance 13 of the second screw bit body 17. This positions the additional gripping point of the second screw bit body 17 adjacent to the second lateral edge 4 of the second screw bit body 17.
In another embodiment of the present invention, referring to FIG. 5 the at least one engagement cavity 6 comprises a first cavity 19 and a second cavity 20.
This embodiment is a simultaneous clockwise and counter-clockwise implementation of the present invention. In particular, the first cavity 19 and the second cavity 20 are oriented parallel and offset to each other. The first cavity 19 is positioned adjacent and offset to the first lateral edge 3 and the second cavity 20 is positioned adjacent and offset to the second lateral edge 4. This allows the user to rotate the present invention either in the clockwise or counter-clockwise rotation without removing the present invention from the torque tool while still taking advantage of the additional gripping point. In this embodiment, it is preferred that the present invention further comprises the plurality of intermittent sidewalls 18, wherein the plurality of intermittent sidewalls 18 is interspersed amongst the plurality of laterally-bracing portions.
7 Referring to FIG. 7, in an alternative embodiment, the present invention is implemented as a ball end screw bit. In this embodiment, the bracing surface 5 of each of the plurality of laterally-bracing sidewalls 2 is a concave surface. As a result, the screw bit body 1 overall has a ball-like shape. This allows the user to engage the socket fastener at an angle, an especially useful feature for fasteners located in hard to reach areas.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
