Abstract
Abstract The involved technical field is that of training appliances for cycling and the application is concerned with a stand device for holding a bicycle stationary while simulating road running conditions. Thetechnical problem was that of providing a device which could simulate with a high degree of verisimilitude road running, and the solution resides in a structure comprising two supporting rollers (2, 3), one for each wheel, which are kinematically connected to each other andto a fan (9) blowing a flow of air against the bicycle (1), the bicycle (1) being supported on means (10, 11, 12, 13) adapted to heel and move sideways.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
90 words
A stand device for holding a bicycle stationary while simulating road running conditions, characterized in that it comprises, carried on a floor resting structure (4), two supporting rollers (2, 3), one for each wheel of the bicycle, kinematically connected to each other and to a fan (9) operative to blow a flow of air against the front portion of the bicycle, means (10, 11, 12, 13) being also provided for so supporting the bicycle as to allow it to undergo movements in the transverse direction and limited deviations from vertical.
Claim 2
Dependent Claim
90 words
A stand device for holding a bicycle stationary while simulating road running conditions, characterized in that it comprises, carried on a floor resting structure (4), two supporting rollers (2, 3), one for each wheel of the bicycle, kinematically connected to each other and to a fan (9) operative to blow a flow of air against the front portion of the bicycle, means (10, 11, 12, 13) being also provided for so supporting the bicycle as to allow it to undergo movements in the transverse direction and limited deviations from vertical.
Claim 3
Dependent Claim
32 words
A stand device according to Claim 1, characterized in that said rollers (2, 3) are kinematically connected to each other and to said fan (9) by means of drive chains (5, 6).
Claim 4
Dependent Claim
47 words
A stand device according to one or both of the preceding claims, characterized in that said fan (9) is positioned on said floor resting structure (4) with the blades thereof facing the front portion of the bicycle and is driven by means of a flexible cable (8).
Claim 5
Independent Claim
62 words
A device according to one or more of the preceding claims, characterized in that said fan (9) is located close to the base of said floor resting structure (4) such as to be driven through a simplified kinematic train (6), and has at the delivery end thereof an air duct for directing said air flow against the front portion of the bicycle.
Claim 6
Independent Claim
31 words
A device according to one or more of the preceding claims, characterized in that said fan (9) is driven by an electric motor having a rheostat linked to the pedal movement.
Claim 7
Independent Claim
29 words
A device according to one or more of the preceding claims, characterized in that said fan (9) is connected to the pedal movement by means of a hydraulic circuit.
Claim 8
Independent Claim

A device aacording to one or more of the preceding claims, characterized in that said bicycle wheel supporting rollers (2, 3) are provided with means of changing rolling resistance to the movement of said wheels (la, 1b) and of a high inertia.
Claim 9
Independent Claim
43 words
A device according to one or more of the preceding claims, characterized in that said rollers (2, 3) can be secured to said floor resting structure (4) at adjustable positions, and that a tensioner (5a) is provided for the drive chain (5) therefor.
Claim 10
Independent Claim
75 words
A device according to one or more of the preceding claims, characterized in that said means (10, 11, 12, 13) of supporting the bicycle comprise a fork (10) having clamps (10a, 10b) for attachment to the frame tubes at the rear, being connected for rotation about the longitudinal axis to a small rod (11) extending from a slider (12) associated with a slideway (13) carried in a transverse direction by said floor resting structure (4).
Claim 11
Independent Claim
