Bicycle trainer with variable resistance to pedaling
First Claim
Patent Images
1. A bicycle trainer for removably attaching a bicycle having a front tire and a back tire to a platform and providing variable resistance to pedaling, comprising:
- a lifting mechanism engaging the front tire of the bicycle, wherein said lifting mechanism comprises a height controller for raising and lowering the from tire on the bicycle;
a pivot bar housed within the bicycle trainer;
a frame connector connected to said pivot bar, said frame connector being attachable to the bicycle to pivot the bicycle about said pivot bar, along an arcuate path, as said lifting mechanism raises and lowers the front tire of the bicycle;
a resistance cylinder providing resistance to the rear tire of the bicycle;
wherein the pivoting of the bicycle creates variable resistance as a function of rear tire pressure against said resistance cylinder, as determined by an angular position of said frame connector relative to a platform.

Abstract
The invention is a bicycle trainer to which a standard bicycle temporarily attaches for exercise and simulated rides. A lifting mechanism raises and lowers the front tire, and in preferred embodiments, a frame engages the rear tire to hold the rear tire in an elevated position against a resistance cylinder. The trainer includes support arms that connect to the bicycle and pivot the bicycle in an arcuate path back and forth in relation to a resistance cylinder. The resistance cylinder can thereby vary resistance against back tire revolution.

15. A bicycle trainer for removably attaching a bicycle having a front tire and a back tire to a platform and providing variable resistance to pedaling, comprising:
-
a lifting mechanism engaging the front tire of the bicycle, wherein said lifting mechanism comprises a height controller for raising and lowering the front tire on the bicycle; a pivot bar housed within the bicycle trainer; a frame connector connected to said pivot bar, said frame connector comprising first and second support bars extending from said pivot bar, wherein said first support bar extends toward the front tire of the bicycle and said second support bar comprises a substantially horizontally portion and a vertical riser connected to the bicycle, wherein said first and second support bars pivot the bicycle along an arcuate path, as said lifting mechanism raises and lowers the front tire of the bicycle; a resistance cylinder providing resistance to the rear tire of the bicycle; wherein the pivoting of the bicycle creates variable resistance as a function of rear tire pressure against said resistance cylinder, as determined by an angular position relative to a platform of said substantially horizontal portion of said second support bar. - View Dependent Claims (16, 17, 18, 19, 20)
