This invention relates to improved methods and apparatus concerning drill chucks and socket wrenches.
Typically in the prior art a drill chuck is provided separately from a socket wrench.
In one embodiment of the present invention an apparatus is provided comprising a socket portion, a chuck device, a handle device, and a central member fixed to the socket portion, chuck device, and the handle device. The central member may have an axis. The handle device can be used to turn the central member in a first direction about the axis while the central member remains stationary. When the handle device turns the central member in the first direction about the axis, the socket portion turns such that the socket portion can be used to exert torque on a fastener. In addition, when the handle device turns the central member in the first direction about the axis, the chuck device turns such that the chuck device can be used to exert torque on a drill bit holding device.
The handle device may be comprised of a left member and a right member. Each of the left member and the right member may be fixed to the central member so that each of the left member and the right member is substantially perpendicular to the central member. The socket portion may be fixed at a first end of the central member and the chuck device may be fixed at a second end of the central member, wherein the first end is substantially opposite the second end. The central member may be metal, rigid, and substantially cylindrical.
In one embodiment of the present invention a method is provided including providing a socket portion, providing a chuck device, providing a handle device, and fixing a central member to the socket portion, chuck device, and the handle device.
Referring to
The socket portion 12 may be a typical socket used for a socket wrench. The socket portion 12 may have a top surface 14, a cavity 16, a cylinder 18, and a section 20. The cavity 16 may be rectangular. A rectangular head of a nut or bolt can be inserted into the cavity 16. The section 20 may have an outer diameter, which gradually decreases from end 20a adjacent the cylinder 18 to end 20b adjacent the member 30.
The member 30 may be substantially cylindrical. The member 30 may rigid, metal, and hollow. The handle device 40 may be comprised of left member 46 and right member 44. Each of the left member 46 and the right member 44 may be substantially perpendicular to the member 30. Each of the left member 46 and the right member 44 may be substantially cylindrical, metal, rigid, and solid. The left member 46 may have a free end 46a and an end 46b, which is fixed to the member 30 through an opening 36. Similarly, the right member 44 may have a free end 44a and an end 44b, which is fixed to the member 30 through an opening 34.
The chuck device 50 may include a plurality of ridges 52. The plurality of ridges 52 include ridges 52a, 52b, 52c, 52d, 52e, 52f, 52g, 52h, 52i52j, 52k, and 52l as shown by
The member 60 may be fixed, substantially centrally, to the bottom of the chuck device 50. The member 60 may be rigid, substantially cylindrical, metal, and solid.
In operation the apparatus 10 can be used as a socket wrench or as a drill chuck. A rectangular nut or bolt head, such as 102 shown by dashed lines in
The end 10b of the apparatus 10 and the ridges 52a-52l can be applied to a drill chuck and the apparatus 10 rotated, about the axis A, so that the member 30 remains stationary in order to tighten a drill bit onto a drill bit holding device on a drill. The apparatus 10 can be rotated so that the members 46 and 44 of the handle device 40 move about the axis A, clockwise or counter counterclockwise, while the member 30 is turned but remains stationary.
Although the invention has been described by reference to particular illustrative embodiments thereof, many changes and modifications of the invention may become apparent to those skilled in the art without departing from the spirit and scope of the invention. It is therefore intended to include within this patent all such changes and modifications as may reasonably and properly be included within the scope of the present invention’s contribution to the art.
