Training apparatus
Training apparatus arranged for supporting a bicycle, comprising a ground-supported or supportable frame that is at least provided with a supporting roll or rollers for a bicycle back wheel that are movable in the frame in vertical direction, wherein the suspension of said roll or rollers is arranged to convert relative horizontal movements of the roll or rollers into vertical movements thereby compensating and/or attenuating said horizontal movements by gravity.
1. Training apparatus arranged for supporting a bicycle, comprising a ground-supported or -supportable frame that is at least provided with a supporting roll or rollers for a bicycle back wheel that are movable in the frame, wherein at least the supporting roll or rollers for the bicycle back wheel are movably suspended in the frame in vertical direction, and wherein the suspension of said roll or rollers is arranged to convert relative horizontal forward and backward movements of the roll or rollers in a plane defined by the frame and induced by acceleration or deceleration of the bicycle into vertical movements in said plane defined by the frame thereby compensating and/or attenuating said horizontal movements by gravity.
2. Training apparatus according to claim 1 , wherein at their extremities the roll or rollers for the bicycle back wheel are directly or indirectly supported by at least one pendulum arm that has a fixed pivoting point on the frame.
3. Training apparatus according to claim 1 , wherein there are two rollers for the bicycle back wheel, wherein at their extremities the rollers for the bicycle back wheel are directly or indirectly suspended by double pendulum arms arranged in the form of a parallelogram construction, wherein the pendulum arms are provided with a connecting link to secure their concerted swinging back and forth.
4. Training apparatus according to claim 1 , wherein the roll or rollers for the bicycle back wheel are supported by a subframe, the subframe is provided within the frame and connects to the frame by means of a pendulum arm or arms.
5. Training apparatus according to claim 1 , wherein the roll or rollers for the bicycle back wheel are suspended in a curved slit or slits that are arranged in the frame.
6. Training apparatus according to claim 5 , wherein the curved slit or slits possess a lowest point approximately in the middle of said slit or slits.
