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...
