Gymnastic machine

Abstract

Gymnastic machine having a frame (10) and an exercise station (20) provided with at least one footrest (30) movable with respect to the frame (10) along a first open trajectory (P1); each footrest (30) being supported rotatably by a first rocker arm (42) in turn supported by a second rocker arm (44) coupled rotatably to the frame (10); a device (50) to control rotation of the first rocker arm (42) being carried on the second rocker arm (44) to minimise the size of the volumes engaged by movable masses in the exercise station (20) and around each footrest (30).

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a machine effectively usable for performing physical exercises. In particular, the present invention relates to a gymnastic machine having at least one pair of footrests for the repeated performance of alternating movements along an open trajectory. In more detail, the present invention relates to a gymnastic machine provided with at least a pair of footrests for repeatedly performing alternating movements along an open trajectory for training with prolonged cyclical exertions of the lower limbs. [0003] 2. Description of the Prior Art [0004] In the field of gymnastic machines there are well-known skating simulators for training of the lower limbs particularly suitable for cardiovascular training sessions. [0005] Some machines of this type are produced in implementation of patents whose teachings have already been described and discussed in U.S. patent application Ser. No. 10 / 908,316 ...

AI Technical Summary

Benefits of technology

[0008] The present invention relates to a machine effectively usable for performing training exercises. In more detail, the present invention relates to a gymnastic machine having at least one pair of footrests for the repeated performance of alternating movements along an open trajectory. Therefore, this invention can be effectively applied both to gymnastic machines aimed principally at muscular development and to machines suitable for the training with prolonged cyclical exertions of the lower limbs.

Problems solved by technology

This peculiarity makes the bill of materials of the gymnastic machine constructed according to the dictates of application Ser. No. 10 / 908,316 particularly intricate and complex, and consequently the machine can only be produced with high production investments, due to the large amount of equipment required by the considerable number of pieces of different shapes and dimensions, even if for identical functions.

Therefore, each footrest must have a corresponding support with a considerable cost and a particularly compact mechanism in which the respective components frequently overlap one another.

Furthermore, the design and production of this casing will be particularly complex, and will involve a considerable commitment in relation to the cost for the respective design, production, assembly and maintenance operations.
