Patent ID: 8652015

Claim:
A safety device for a gymnastic machine provided with a frame and with a gravitational load group connected to an interface designed so as to allow a user of said gymnastic machine to perform exercises against the action of said load group; said load group including a movable equipment provided with at least one load element carried, in a freely sliding manner along a given direction, by respective guiding means associated with said frame; said safety device comprising: first coupling means carried integrally by said frame; return means including at least one elongated elastic element adapted to connect said frame to said movable equipment to exert a given return force on said movable equipment so as to prevent substantially inertial ascending displacements thereof; said at least one elastic element having a respective first end portion rigidly coupled to said load group, and a second end portion provided with abutment means shaped so as to couple in a stable and selectively releasable manner with said first coupling means; and a mechanical switching device adapted to enable selectively the coupling between said abutment means and said first coupling means in order to allow a user to selectively switch between an actuated or deactivated operative status of said return means.
