Definitions

  • the invention relates to a tool handle.
  • Tool handles are available for receiving tools from a range of different tools.
  • Such tool handles generally comprise a body in which a tool may be placed.
  • An advantage of such a tool handle is that it enables a single handle to be used with a range of different tools, thus reducing the physical size of a craftsman's tool kit without reducing the range of tools available to the craftsman.
  • Such tool handles are commonly, but not exclusively, used with a rotatable tool such as a screw driver.
  • the present invention aims to provide an improved tool handle.
  • a high torque tool handle comprising: a handle having a longitudinal axis and further having a tool end and a distal end; the handle including an elongate recess aligned parallel to the longitudinal axis of the handle; an elongate gripping member sized to be received within the recess and positioned therein; a pin means positioned in the recess adjacent the distal end of the handle and connected to a corresponding end of the gripping member for pivotally connecting the gripping member may be pivoted about one end of the gripping member out of the recess to an extended position.
  • a tool handle comprising a body for receiving a rotatable tool and a lever arm mounted to the body, the lever arm being extendible fro the body to enable a greater turning force to be applied through the tool handle to a tool received in the body and being retractable to a storing position substantially within the body.
  • a high-torque tool handle 10 is shown in Figure 1 of the accompanying drawings.
  • Handle 10 at one end has a bore 14 with a tool holder 12 rigidly held within the bore 14.
  • tool holder 12 had ridges 16 raised from the circumference adjacent one end and sized slightly larger than bore 14 so that tool holder 12 can be held rigidly with handle 10.
  • a Phillips head screw driver tool 18 may be held with tool holder 12.
  • additional hexagonal bores 19 are offset from bore 14 so as to hold spare hexagonal tools 18 whenever the spare tools are not in use.
  • a rotatable hand grip 20 Adjacent the opposite end of a handle 10, a rotatable hand grip 20 rotates about a spring-pin 22, which is sized to maintain the grip 20 in any desired rotated position through friction.
  • Hand grip 20 can be extended for additional leverage when rotating the handle 10 and thus serves as a lever arm, or can be retracted into a recess 24 in the handle.
  • ledges 26 extend along handle 10 beneath hand grip 20 whenever the hand grip is retracted.
  • Ledges 26 act as a stop for hand grip 20 as the hand grip rotates into handle 10 whenever hand grip 20 is retracted.
  • Recess 24 is also sized in length so as to permit easy access for a finger to engage lip 28 so as to lift the hand grip from the handle and extend the hand grip whenever desired.
  • the hand grip has an I-section.
  • Tool holder 12 at one end has a hexagonal opening 30 for accepting a tool 18. As shown in Figure 7, adjacent the bottom of hexagonal opening 30 is a magnet 32 for holding tool 18 within opening.
  • FIG. 8 An alternate embodiment of tool holder 12 is shown in Figure 8. Adjacent one end are ridges 16 sized to be slightly larger than bore 14 in handle 10 so that the tool holder can be held rigidly within the tool end of the handle.
  • the tool holder 12 comprises a shaft having a tool receiving opening 30.
  • a movable sleeve 34 is slidably mounted on the shaft and can lock or unlock a ball detent 36 mounted on the shaft adjacent the tool receiving opening 30.
  • the ball is movable from a position outside the opening to a position inside the opening to hold a tool received by the tool receiving opening.
  • the sleeve 34 cooperates with the ball detent 36 to move the ball detent from the outside position to the inside position when the sleeve slides over the ball.
  • ball detent 36 is used to lock another tool 18 within hexagonal opening 30.
  • This locking mechanism is the same as that shown in Figures 4A and 4B in U.S. Patent No. 5,470,180 to Jore and described therein.
