1. A translational-rotary machine (1) comprising a first and second motor means (4, 4′) and translational-rotary members (3), wherein the translational-rotary members (3) comprise:
a movable carriage (13);
a lower shaft (15) passing through the carriage (13);
a first return pulley (16) integrally keyed onto the lower shaft (15) on a front side (7) of the translational-rotary machine (1);
a first toothed wheel (17) integrally keyed onto the lower shaft (15) on a rear side (8) of the translational-rotary machine (1);
an upper shaft (14) passing through the carriage (13), said upper shaft (14) being vertically aligned with the lower shaft (15);
a second return pulley (18) idly mounted onto the upper shaft (14) on the rear side (8) of the translational-rotary machine (1);
a first transmission member (20) arranged on the front side (7) of the translational-rotary machine (1), said first transmission member (20) being adapted to operatively connect the first and second motor means (4, 4′) to the first return pulley (16);
a second transmission member (21) arranged on the rear side (8) of the translational-rotary machine (1), said second transmission member (21) being adapted to operatively connect the first and second motor means (4, 4′) to the second return pulley (18);
wherein the second return pulley (18) is operatively connected to the first toothed wheel (17) by means of a second toothed wheel (19), so that the force transmitted by the second transmission member (21) acts on an upper section of the first toothed wheel (17),
and wherein the force transmitted by the first transmission member (20) acts on a lower section of the first return pulley (16);
a frame (2) on which translational-rotary members (3) are mounted, which are configured to move limbs of the user, said translational-rotary members (3) being operatively connected to the first and second motor means (4, 4′), wherein the frame (2) comprises a support structure (5) for the translational-rotary members (3), which extends along a longitudinal axis X,
wherein the translational-rotary members (3) comprise:
a first pair of pulleys (11, 11′) arranged on the front side (7) of the translational-rotary machine (1), at the ends of the support structure (5), the pulleys (11, 11′) of said first pair being aligned along an axis which is substantially parallel to the axis X;
a second pair of pulleys (12, 12′) arranged on the rear side (8) of the translational-rotary machine (1), at the ends of the support structure (5), the pulleys (12, 12′) of said second pair being aligned along an axis which is substantially parallel to the axis X;
the carriage (13) which is movable along the axis X, wherein said carriage (13) has a symmetry axis Y of the carriage which is perpendicular to the axis X;
wherein said carriage (13) comprises:
a first pair of tension pulleys (9, 9′) arranged on said carriage (13), on the front side (7) of the translational-rotary machine (1), the tension pulleys (9, 9′) of said first pair being arranged along an axis which is substantially parallel to the axis X;
a second pair of tension pulleys (10, 10′) arranged on said carriage (13), on the rear side (8) of the translational-rotary machine (1), the tension pulleys (10, 10′) of said second pair being arranged along an axis which is substantially parallel to the axis X;
the upper shaft (14) passing through the carriage (13), substantially arranged at the axis Y and oriented in the direction Z;
the lower shaft (15) passing through the carriage (13), substantially arranged at the axis Y and oriented in a direction Z;
the first return pulley (16) integrally keyed onto the lower shaft (15) on the front side (7) of the translational-rotary machine (1);
the first toothed wheel (17) integrally keyed onto the lower shaft (15) on the rear side (8) of the translational-rotary machine (1);
the second return pulley (18) idly mounted onto the upper shaft (14) on the rear side (8) of the translational-rotary machine (1);
a second toothed wheel (19) idly mounted onto the upper shaft (14) on the rear side (8) of the translational-rotary machine (1), said second toothed wheel (19) being integral with the second return pulley (18);
the first transmission member (20) which operatively connects said first pair of pulleys (11, 11′), the first pair of tension pulleys (9, 9′) and the first return pulley (16);
the second transmission member (21) which operatively connects said second pair of pulleys (12, 12′), the second pair of tension pulleys (10, 10′) and the second return pulley (18);
and wherein the first toothed wheel (17) is operatively meshed with the second toothed wheel (19).
