Abstract
A handlebar shock absorbing system for bicycles, utilizing a pair of side plates attached to a handlebar mounting bracket with rotational movement of a handlebar against a torsional spring. Where the handlebar can be adjustable for torsional spring force and/or for rotational travel and positioning of handlebar grips, either forward tilting, level or rearward tilting.
Claims20
A handlebar shock absorbing system for bicycles, comprising:
- a) a handlebar;
- b) a pair of adjustably mounted handlebar grips;
- c) a handlebar mounting bracket;
- d) a pair of side plates attached to said handlebar mounting bracket, having opposing apertures for rotatably mounting of said handlebar;
- e) a releasable and lockable handlebar torsion bracket;
- f) a helical torsion spring having at least two connecting ends;
- g) and a means for adjusting said torsion spring force;
- wherein said torsion spring is mounted to said handlebar torsion bracket at a first end of said torsion spring and said torsion spring is mounted at least one of said pair of side plates at an opposite second end of said torsion spring,
- wherein said handlebar is journalled through said helical torsion spring.
6 more elements
A handlebar shock absorber comprising:
- a handlebar pivotally mounted to a mounting bracket for rotation of said handlebar between a rest position and a depressed position, said mounting bracket rigidly mountable to the upper end of a handlebar stem so that an axis of rotation of said handlebar is substantially co-axial with a longitudinal axis of said handlebar whereby rotation of said handlebar rotates said handlebar about said longitudinal axis,
- resilient biasing means mounted to, so as to cooperate between, said handlebar and said mounting bracket, said resilient biasing means resiliently biasing said handlebar into said rest position and resiliently urging said handlebar to return to said rest position when rotated towards said depressed position.
