AI Technical Summary

Benefits of technology

[0009]Furthermore, the present invention relates to a lever for this gymnastic machine, this lever being designed to contain the overall mass of the machine with the same resistance to torsional loads, to increase the safety degree of the machine in its entirety, and to simplify the structure thereof.

Problems solved by technology

This contributes toward placing manufacturers in the position of choosing whether to strengthen the resistant cross-sections or to complicate the shape of the levers with the result of compromising the aesthetic appearance, as already described above.
In view of the above description, the problem of having available a gymnastic machine in which the interaction between the implement and the corresponding load group is carried out by means of levers of simple shape, light, carried by the frame through a single hub and, simultaneously, capable of withstanding the exchange of high energy values in the unit of time and of high torsional stresses with the respective pin for connection to the frame is currently unsolved.

Embodiment Construction

[0016]In FIG. 1, number 1 indicates, in its entirety, a gymnastic machine 1 comprising a frame 10, a load group 20 carried by the frame 10, at least a gymnastic implement 30 connected to the load group 20 through at least a transmission member 40 to exchange energy with the load group 20. This transmission member 40 comprises at least a box-shaped lever 42 that is very light and has considerable torsional rigidity, as it will be apparent from the description below; each lever 42 is provided with a coupling device 45 connected to the frame 10 by means of a pivot pin 60. Each implement 30 presents maximum transverse extension equal to D, which in the case of the implement 30 being obtained from a cylindrical bar, would coincide with the respective diameter.

[0017]As shall become readily apparent from the present description, the machine illustrated in FIG. 1 is of the free weight type, but this choice does not detract from the general nature of the teachings provided, which can be effe...

Abstract

A gymnastic machine (1) includes a frame (10), a load group (20), and at least one gymnastic implement (30) suitable to exchange energy with the load group (20) through at least one box-shaped lever (42) having a transverse cross-section (S) of predetermined shape and longitudinally adjustable width, with a respective lateral profile (PL) having a height decreasing according to a direction of travel that leads to the respective implement (30).

Description

[0001]The present invention relates to a gymnastic machine provided with at least a lever. In particular, the present invention relates to a gymnastic machine provided with at least a lever usable to actuate a load group. In more detail, the present invention relates to a gymnastic machine provided with at least a lever usable to actuate a load group and to a method for producing this lever.BACKGROUND TO THE INVENTION[0002]In the field of gymnastic equipment, it is known to manufacture gymnastic machines provided with levers pivoted to a frame supporting a load group, normally of the gravitational, hydraulic or electromagnetic type. These levers are of the substantially box-shaped type in order to optimise the ratio between the mass and the mechanical resistance and to minimise the cost thereof. Normally, these levers are produced by cutting bars which have a constant and generally rectangular cross-section to be more easily machinable. Again in order to optimise the ratio between t...
