Abstract
Abstract The involved technical field is that of bicycles, and the invention is corned with a stand device for holding a bicycle stationary while simulating road running conditions. The technical problem was that of providing a device which could simulate road running conditions with a high degree of verisimilitude and the solution resides in a structure comprising two supporting rollers, one for each wheel, which are kinematically connected to each other and to a fan, adapted to generate a flow of air blowing against the bicycle, the bicycle being supported on means adapted to heel and move sideways.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
245 words
An apparatus for holding a bicycle stationary while simulating road running conditions, said apparatus comprising a floor resting structure having a longitudinal and a widthwise extension, a supporting front roller for the front wheel of the bicycle and longitudinally at a distance therefrom a supporting rear roller for the rear wheel of the bicycle, said front roller and said rear roller being substantially parallel to each other and mounted for rotation on said floor resting structure, a fan on said floor resting structure and holding means for yieldably holding the bicycle in position on said rollers, wherein said fan comprises a frame portion mounted on said supporting structure and an impeller mounted for rotation on said frame and wherein the apparatus further comprises transmission means between said front roller and said rear roller, said transmission means having a section transmissively connected with said impeller, thereby to transmit rotatory motion to said impeller when rotation is imparted by the bicycle user to said rear roller through the rear wheel of the bicycle, and wherein said holding means for yieldably holding the bicycle in position comprise a slideway extending transverse to said longitudinal extension and supported by said floor resting structure, a slider slidable on said slideway, a rod member connected with said slider and having a longitudinal axis extending in said longitudinal direction, a fork connected with said rod member for rotation about said longitudinal axis, said fork having clamps for attachment to the bicycle frame.
