Abstract:
A physical training machine with attitude adjustment, comprising:a posture portion provided with a positioner, said positioner constructed and arranged to allow positioning of a user set to execute a physical training exercise;an implement portion having an action accessible to said user when positioned in an exercise configuration, said action constructed and arranged to allow said user to apply a force in opposition to a resistance offered by the physical training machine;an adjuster, constructed and arranged to adjust a relative position between said posture portion and said implement portion acting on one thereof; anda connector, positioned and acting between said posture and implement portions so as to modify the position of one of said portions in response to a change in position of the other one of said portions,wherein said connector comprises a plurality of extended members mutually constrained in such a way as to transmit, with a given transmission ratio, the motion related to a displacement of said posture position into a displacement of said activator,wherein said activator comprises a footrest pivoted on a first axis, said posture portion comprising a support structure for said user, movable with respect to a base structure through said adjuster and said connector comprises:a first rod, fastened in a first end to said support structure;a first lever, with its fulcrum around a second pin fixed with respect to said base structure and connected, in its first end, to the second end of said first rod;a second rod, fastened in its first end to a second end of said first lever; anda second lever, fastened to the second end of said second rod and with its fulcrum around a third pin fixed with respect to said base structure, and connected to said footrest through a third rod supporting the same, angularly positioned with respect to said second lever in such a way as to make the displacements executed upstream on said posture portion, correspond to a rotation of said third rod suitable to position said footrest in a configuration derived from the positioning of said posture portion.
