Benefits of technology

[0021] An object of the present invention is to obviate the disadvantages described above through a mechanism of the type mentioned above, of limited dimensions, in which the adjustment of the path of the application pin applying the load is performable during use.

Problems solved by technology

Another disadvantage, furthermore, is represented by the fact that adjustment of the mechanism through variation of the distance of the application pin applying the load, from the centre of the satellite member is an operation feasible only with the machine stationary.

Embodiment Construction

[0037] In accordance with the attached drawings, in FIGS. 1 and 2, reference numeral 1 globally identifies a machine for gymnastic exercise which includes a frame 20 supporting a pair of epicycloidal mechanisms adjacent to each other and located symmetrically with respect to a vertical longitudinal median plane of machine 1, not illustrated in the attached drawings for convenience. The two mechanisms 2 are therefore capable of being activated in two respective parallel planes, vertical and longitudinal, of machine 1.

[0038] Each mechanism 2 includes a member 3 for applying a driving load to a reaction device 36, better visible in FIG. 3a. The driving load is generated by the muscular action of a user of machine 1 and, by means of footboard 35 is transmitted to each application member 3 of the two mechanisms 2. The reaction device 36 can be created ad hoc but can also reproduce a constructive structure already tested and described in a number of patent applications by the applicant, ...

Abstract

Gymnastic machine including an epicycloidal mechanism (2) for connecting an application member (3) of a driving device to resistive means (36); the mechanism (2) being provided with a satellite member (4) connected to the application member (3) by means of a first crank (5) having a pin (6); with a planetary member (7); with a second crank (8) which rotationally connects a movable rotation centre (9) on the satellite member (4) to a fixed centre (10) on the planetary member (7); and with transmission devices (11, 12, 13) for transmitting a relative motion between the satellite member (4) and the planetary member (7); the planetary member (7) being supported in freely rotatable manner around an axis (14) passing through the fixed centre (10); actuating members (15) being provided for imparting to planetary member (7) an angular movement (α) around the fixed centre (10) which corresponds to a relative angular variation (β) of the first and second cranks (5, 8), and a corresponding variation of the orientation of the path (21, 22) of the pin (6) of the satellite member (4).

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a gymnastic machine. In particular, the present invention relates to a gymnastic machine which includes an epicycloidal mechanism. In more detail, the present invention refers to a gymnastic machine which includes an epicycloidal mechanism capable of connecting together a device capable of producing a resistive load to an organ for the application of a driving load. [0003] 2. Description of the Prior Art [0004] A mechanism is known from document U.S. Pat. No. 6,334,836, in the name of the present Applicant, of general use which, if applied to a machine for gymnastic exercise, may be usefully employed for connecting a member for applying a muscular driving load, generated by the user of the machine, to resistive means opposing the applied muscular load. The mechanism essentially includes: [0005] a satellite member (an externally-toothed wheel) rigidly carrying a first crank, radial, h...
