Definitions

  • 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.
  • 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.
  • 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.
  • the present invention generally related to torque tool accessories. More specifically, the present invention is a multi-grip screw bit, also known as a screw bit or driver.
  • the present invention allows for a higher torque to be applied to a fastener than a similarly sized conventional driver bit without damaging the head of the fastener or the bit tool. This is achieved through the use of a multitude of engagement features which effectively grip the head of the fastener.
  • the present invention is a screw 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.
  • 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 14, and a second base 15.
  • 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 torque tool to the socket fastener.
  • the first base 14 and the second base 15 are positioned opposite to each other along the plurality of laterally-bracing sidewalls 2. Additionally, the first base 14, and thus second base 15, is preferably oriented perpendicular to each of the plurality of laterally-bracing sidewalls and thus enclose/complete the prism shape of the screw bit body 1. More specifically, it is preferred that the first base 14 comprises a first base surface 26, wherein the first base surface 26 is flat and is oriented perpendicular to the bracing surface 5 of each of the plurality of laterally-bracing sidewalls 2.
  • the attachment body 19 allows it to be attached to an external torque tool and, thus, allow torque force to be applied to the socket fastener through the screw bit body 1.
  • the attachment body 19 is centrally positioned around and along a rotation axis 16 of the screw bit body 1 such that the rotation axis of the attachment body 19 and the rotation axis 16 of the screw bit body 1 are coincidentally aligned. Additionally, the attachment body 19 is connected adjacent to the second base 15.
  • the attachment body 19 preferably has a hexagonal cross-section in order to fit within a female attachment member of the external torque tool.
  • External torque tools include, but are not limited to, electric drills, torque wrenches, pneumatic drills, socket screw drivers, and other similar torque tools.
  • the entire cross-section 9 of the at least one engagement cavity 8 is a triangular profile.
  • This arrangement provides ample space while applying torque for relief of residual stresses and material that would otherwise strain the at least one engagement cavity 8.
  • the triangular profile is concave along a direction from the first lateral edge 3 to the second lateral edge 4. In this way, torqueing stresses are captured within the at least one engagement cavity 8 during the application of torsion.
  • the triangular profile may further comprise a plurality of vertexes 27, as represented in FIG. 15 .
  • the plurality of vertexes 27 relates to the locus of points representing corners of the triangular profile.
  • Each of the plurality of vertexes 27 may be a rounded corner. This arrangement prevents point stresses from building at the plurality of vertexes 27 without significantly reducing the space required for effective mitigation of fatigue effects.
  • the triangular profile may comprise a plurality of vertexes 31 and a pair of elongated portions 32, as shown in FIG. 16 and 17 .
  • the plurality of vertexes 31 relates to a set of points representing the corners of the triangular profile.
  • the plurality of vertexes 31 may be viewed as two leading edge elements along the first lateral edge 3 and the second lateral edge 4 and one cavity base element.
  • the one cavity base element may also be a straight line connected to the pair of elongated portions 32.
  • the pair of elongated portions 32 denotes the edges which join the plurality of vertexes 31 together.
  • the pair of elongated portions 32 is interspersed amongst the plurality of vertexes 31.
  • the pair of elongated portions 32 connects each of the plurality of vertexes 31 together.
  • Each of the pair of elongated portions 32 is a shape selected from the group consisting of: straight line, concave, and convex.
  • the group of shapes that may be selected for the plurality of vertexes 31, the pair of elongated portions 32, or the one cavity base element may be a radius or angular shape. This arrangement enables the pair of elongated portions 32 to better adapt to different torqueing stresses, thus preventing detrimental wear upon the used bit due to fatigue.
  • a bracing surface 5 comprises a first portion 33 and a second portion 34, as shown in FIG. 16 and 17 .
  • the first portion 33 and the second portion 34 relate to the edges surrounding the triangular profile.
  • the first portion 33 is positioned along a first distance 21, which arranges the first portion 33 adjacent to the first lateral edge 3.
  • the second portion 34 is positioned along a second distance 22, which arranges the second portion 34 adjacent to the second lateral edge 4.
  • the first portion 33 is a shape selected from the group consisting of: concave, and convex. In this way, the first portion 33 may be adapted to best address potential mechanical fatigue to the present invention.
  • the second portion 34 is a shape selected from the group consisting of: concave and convex. In this way, the second portion 34 may be adapted to best address potential mechanical fatigue to the present invention.
  • the group of shapes that may be selected for the first portion 33 and a second portion 34, as shown in FIG. 16 and 17 may be a radius or angular shape. It is often most advantageous for the first portion 33 and the second portion 34 to display opposite curvatures, with one being concave and the other being convex, for optimal reduction of cyclical stress-based effects on the present invention. Additional modifications may be implemented to the first lateral edge 3 and the second lateral edge 4 to form lateral edges which are angular or radial in shape.

  • the first lateral edge 3 and the second lateral edge 4 are positioned opposite to each other across the bracing surface 5.
  • 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.
