Abstract
A bicycle trainer adapted to support a conventional bicycle with the front wheel removed. The bicycle is attached to a pivot frame at the front forks and the rear axle. The pivot frame is pivotably attached to the base frame and supported in a substantially upright position by springs. Both the bicycle and pivot frame pivot about an imaginary tire contact-line, which simulates real bicycle riding conditions associated with bicycle sprinting and hill climbing.
Claims9
A bicycle trainer for use with a conventional bicycle with the front wheel removed, the trainer comprising:
- (a) a pivot frame having substantially rigid contiguous parts including;
- a substantially vertical front member, having a front fork mount, for detachably supporting the front forks of a bicycle;
- a substantially vertical rear u-shaped member for detachably supporting the rear axle of said bicycle, an elongated horizontal member defining a longitudinal axis, having a first end supporting said vertical front member and an opposite end supporting said vertical rear member, and further including a tail member substantially in line with said horizontal member;
- (b) a base frame having front and rear rotational coupling means for pivotably supporting said horizontal member of said pivot frame;
- (c) a resistance device attached at a distal end of said tail member of said pivot frame and adapted to be frictionally coupled to the rear tire of said bicycle;
- (d) a spring mechanism having a pair of springs, each having a first end connected to said pivot frame and an opposite end connected to said base frame for pivotably restoring said pivot frame and said bicycle to a substantially vertical neutral position after being pivotably displaced;
- whereby a person may simulate bicycle sprinting and hill climbing by pivoting the bicycle on the training during use.
A bicycle trainer to be used by a person for use with a conventional bicycle with the front wheel removed, the trainer comprising:
- (a) a pivot frame having substantially rigid contiguous parts including;
- a substantially vertical front member, having a front fork mount, for detachably supporting the front forks of a bicycle;
- a substantially vertical rear unshaped member for detachably supporting the rear axle of said bicycle, a cylindrical horizontal member defining an imaginary tire contact line, having a first end supporting said vertical front member and an opposite end supporting said vertical rear member, and further including a tail member extending at a rear portion of said pivot frame and substantially in line with said cylindrical horizontal member;
- (b) a rectangular base frame having front and rear rotational coupling means for pivotably supporting said cylindrical horizontal member at opposite ends;
- thereof
- (c) a resistance device attached at a distal end of said tail member of said pivot frame and adapted to be frictionally coupled to the rear tire of said bicycle;
- (d) a spring mechanism having a pair of springs and a shock absorber having a pair of shocks, each spring and shock having a first end connected to said pivot frame and an opposite end connected to said base frame for pivotably restoring the pivot frame and said bicycle to a substantially vertical neutral position after being pivotably displaced;
- whereby a person may simulate bicycle sprinting, hill climbing, and pedaling while standing on the pedals of the bicycle with no seat contact by laterally pivoting the bicycle about the imaginary tire contact line during use.
