Gymnastic machine

A gymnastic machine for simulating a skating movement, the gymnastic machine comprising:

• a frame carrying one load unit;
• and
• an exercise station for performing a training exercise, the exercise station including:
• a first functional group mechanically connected to the load unit in order to exchange mechanical energy with the load unit, said first functional group including:
• two first levers, and
• two footrests carried symmetrically with respect to a longitudinal median plane, in a rotatable manner and in an open chain by said frame along a given trajectory by the two first levers, with each first lever carrying a respective footrest;
• a second functional group positioned in said exercise station and including:
• two second levers each provided with a handgrip for each footrest;
• transmission means including two third levers each pivoted to said frame and configured to constrain each respective second lever and the respective footrest to operate in phase with the transmission means being positioned between said first and second functional groups in order to connect each second lever to the respective footrest;
• and
• return means carried by said frame and including:
• a first shaft carried in a freely rotatable manner by said frame,
• a pair of first cranks rigidly coupled on said first shaft, and
• a pair of first connecting rods, with each first connecting rod connecting each first lever to a corresponding said first crank in order to mechanically connect said footrests in a rigid manner, with the return means configured to mechanically connect said two footrests so that a descending movement of one of said footrests corresponds to an ascending movement of the other footrest.

• wherein said load unit includes:
• a first shaft,
• a transmission provided with a driven wheel pivoted to the frame for operating the first shaft by the two footrests,
• an electromagnetic brake carried by said frame with the electromagnetic brake operated by the first shaft,
• wherein said transmission farther comprising:
• a spool coaxial to said electromagnetic brake;
• and
• a first belt which connects said drive wheel to said spool in an angularly fixed manner according to a given velocity ratio;
• a pair of freewheels carried by said frame in a rotatable manner in order to mechanically connect said return means and said load unit;
• and
• a pair of interfaces, with each interface connecting a respective freewheel to a respective first lever, with each interface including:
• a second belt, and
• an interface wheel connected to a respective freewheel by a respective second belt, and in that one of said second belts is mechanically coupled to the respective freewheel in a ring fashion while the other of said second belts is mechanically coupled to the respective freewheel in the shape of a figure eight.
