Abstract

A dynamic system for making use of an exercise bicycle supported on front and rear struts, the system permitting the bicycle to sway side to side when ridden vigorously, the system including a first and a second housing for resting on a support surface, a platform retained by each housing, the platform of the first housing serving to receive thereon the bicycle front strut and the platform of the second housing serving to receive thereon the bicycle rear strut, each platform being pivotal end to end and at least one deflectable resilient member engaging each platform and functioning to normally retain the exercise bicycle uprightly.

Claims

1. A dynamic system for making use of a stationary exercise bicycle having a longitudinal axis that extends from a front portion to a rear portion of the bicycle and front and rear cross members disposed perpendicularly to said longitudinal axis, the system comprising:

a first housing adapted to rest on a support surface and a separate second housing adapted to rest on the support surface;

each housing having a platform and a pair of centrally located bearing pads, each bearing pad having a groove;

each said platform having a generally horizontal upper surface, the platform of said first housing having a pair of straps to removably couple thereon the bicycle front cross member and the platform of said second housing having a pair of straps to removably couple thereon the bicycle rear cross member, each said platform being pivotable end to end about a tubular rod having a longitudinal axis and centrally located on the underside of said platforms in a pair of tubular collars that rest on said grooves of said bearing pads; and

at least one deflectable resilient member disposed between each said platform and each said respective housing functioning to normally retain the exercise bicycle uprightly, said generally horizontal upper surfaces of said platforms serving to conveniently receive and support cross members of said stationary exercise bicycle to thereby easily and readily convert said stationary exercise bicycle to one that sways side to side about the longitudinal axis of the tubular rod when vigorously ridden.

2. A dynamic system according to claim 1 wherein each said platform is normally supported substantially parallel to the support surface on which said housings are positioned except when the exercise bicycle is being ridden vigorously.

3. A dynamic base according to claim 1 wherein each said deflectable resilient member is in the form of at least one spring.

4. A dynamic base according to claim 1 wherein each said deflectable resilient member is in the form of at least one compressible member.

5. A dynamic base according to claim 1 wherein each said deflectable resilient member is in the form of a spring having at least a portion thereof coiled about said axial rod.

6. A dynamic base according to claim 1 wherein each said deflectable resilient member is in the form of a combination of at least one spring and in combination with at least one compressible member.
