Neck-strain alleviator for bicyclists

Claim 1

A device for use to alleviate neck strain of bicyclists by providing hand-adjustability of bicycle handlebar position to bicycle handlebars within a handlebar cavity of a bicycle handlebar stem, the handlebar cavity securing the bicycle handlebars against mmovement when a bolt within a bolt cavity of the stem is tightened, the device being for use both with a stem having a slot within the bolt cavity of the stem, the slot adapted to engage a fin of a bolt, the slot and the fin cooperatively interacting to prevent rotation of the bolt, and with a stem having a ledge, the ledge adapted to abut polygonal-head means of a bolt when the bolt is positioned within the bolt cavity of the stem, the ledge and the polygonal-head means cooperatively interacting to prevent rotation of the bolt; the device comprising: a finned threaded bolt, having a head and shank portion, and a fin, said fin attached to and extending between said head and shank portions, the fin engaging said slot within the bolt cavity of a stem when said finned threaded bolt is positioned within the bolt cavity, the slot and the fin cooperatively interacting to prevent rotation of the bolt; a polygonal-sided slotted collar, having an interior slot, the interior slot engaging the fin of said finned threaded bolt when said collar is positioned upon said finned threaded bolt, thereby rendering said collar non-rotatable relative to said finned threaded bolt, the polygonal sides of said collar then serving as polygonal-head means for said finned threaded bolt, the polygonal-head means adapted to abut said ledge of a stem, when said finned threaded bolt is positioned within the bolt cavity of the stem, the ledge and the polygonal-head means of said collar then cooperatively interacting to prevent rotation of said finned threaded bolt; a handle-support, having therein means adapted to engage a handle, and having therein a threaded cavity receiving said finned threaded bolt, said handle-support threaded onto a protruding threaded end of said finned threaded bolt when said finned threaded bolt is positioned within the bolt cavity of the stem; and a handle, engaged by said handle-support, adapted, when turned to transmit sufficient force to said handle-support when said handle-support is threaded onto said finned threaded bolt positioned within the bolt cavity of the stem, so as to thereby tighten or loosen said finned threaded bolt and thus thereby to tighten or loosen bicycle handlebars within the handlebar cavity of the stem.

Claim 2

A device for use to alleviate neck strain of bicyclists by providing hand-adjustability of bicycle handlebar position to bicycle handlebars within a handlebar cavity of a bicycle handlebar stem, the handlebar cavity securing the bicycle handlebars against mmovement when a bolt within a bolt cavity of the stem is tightened, the device being for use both with a stem having a slot within the bolt cavity of the stem, the slot adapted to engage a fin of a bolt, the slot and the fin cooperatively interacting to prevent rotation of the bolt, and with a stem having a ledge, the ledge adapted to abut polygonal-head means of a bolt when the bolt is positioned within the bolt cavity of the stem, the ledge and the polygonal-head means cooperatively interacting to prevent rotation of the bolt; the device comprising: a finned threaded bolt, having a head and shank portion, and a fin, said fin attached to and extending between said head and shank portions, the fin engaging said slot within the bolt cavity of a stem when said finned threaded bolt is positioned within the bolt cavity, the slot and the fin cooperatively interacting to prevent rotation of the bolt; a polygonal-sided slotted collar, having an interior slot, the interior slot engaging the fin of said finned threaded bolt when said collar is positioned upon said finned threaded bolt, thereby rendering said collar non-rotatable relative to said finned threaded bolt, the polygonal sides of said collar then serving as polygonal-head means for said finned threaded bolt, the polygonal-head means adapted to abut said ledge of a stem, when said finned threaded bolt is positioned within the bolt cavity of the stem, the ledge and the polygonal-head means of said collar then cooperatively interacting to prevent rotation of said finned threaded bolt; a handle-support, having therein means adapted to engage a handle, and having therein a threaded cavity receiving said finned threaded bolt, said handle-support threaded onto a protruding threaded end of said finned threaded bolt when said finned threaded bolt is positioned within the bolt cavity of the stem; and a handle, engaged by said handle-support, adapted, when turned to transmit sufficient force to said handle-support when said handle-support is threaded onto said finned threaded bolt positioned within the bolt cavity of the stem, so as to thereby tighten or loosen said finned threaded bolt and thus thereby to tighten or loosen bicycle handlebars within the handlebar cavity of the stem.
