Abstract
A hook and jack handle assembly in which the hook is retained within the tubular jack handle during use of the assembly in operating a vehicle jack. To this end, a tubular end portion in a jack handle has inserted therein a hook-shaped end piece having a pre-formed indentation. The tubular wall of the jack handle is displaced within the pre-formed indentation such that the end piece is prevented from slipping out of the jack handle during use.
Claims19
A jack handle assembly for use with a vehicle jack comprised of a solid metal end piece having a pre-formed indentation in a portion thereof, said indentation having side walls transverse to a length of the end piece, said portion of the end piece being disposed within a tubular section of a jack handle, and a crimp of a substantial amount of material of the tubular section being displaced into and retained by the pre-formed indentation in the solid metal end piece to prevent the end piece from being slidably disengaged lengthwise from the jack handle.
A jack handle assembly for use with a vehicle jack comprising:
- a solid metal endpiece having a pre-formed indentation in a portion thereof, said indentation having side walls transverse to a length of the end piece;
- a jack handle having a tubular section at one end for receiving the portion of the endpiece, and a crimp of a substantial amount of material of the tubular section being displaced into and retained by the pre-formed indentation in the endpiece to prevent a lengthwise separation of the endpiece from the jack handle.
A jack handle assembly for use with a vehicle jack comprised of:
- a solid metal end piece having a first portion formed adapted to engage with a vehicle jack, and an opposite portion having a pre-formed indentation therein, said indentation having side walls transverse to a length of the end piece;
- and
- a jack handle having a tubular section at one end partially receiving the opposite portion of the solid metal end piece including the pre-formed indentation, and a substantial amount of material of the tubular section being displaced within and retained by the pre-formed indentation in the opposite portion of the solid metal end piece, wherein the end piece is prevented from being slidably disengaged lengthwise from the tubular section.
A handle assembly for use in positioning a vehicle lifting jack beneath a vehicle and for rotating a spindle of the jack, the handle assembly comprising:
- an end piece having
- a first end with a formed tip adapted to engage and transmit rotary motion from the end piece to the rotatable spindle of the vehicle lifting jack, and
- an opposite end with a noncircular cross-sectional profile, the opposite end further including a pre-formed indentation, said indentation having side walls transverse to a length of the end piece;
- and
- a jack handle having one end formed with a tubular section receiving the noncircular cross-section of the opposite end of the end piece in driving engagement such that rotation of the jack handle is operable to effect rotation of the end piece, the tubular section having a substantial amount of material disposed within and retained by the pre-formed indentation of the opposite end of the end piece, wherein the end piece is prevented from being slidably disengaged lengthwise from the tubular section.
