Electromechanical system for selecting weights in fitness station weights towers

An electromechanical system for selecting weights in fitness station weights towers comprising:

• a tower, formed by vertical columns, upper crosspiece, base, with a stack of plates of unit weights, with vertical guides inside the tower, fixed to the upper crosspiece and to the base, with a stack of plates headed by a cursor which at the center fastens to steel cable that lifts the weights, the cursor having a central rod projected downwards, penetrating into central holes of all the plates and provided with a vertical screw disposed at a hollow center of the rod and mounted thereon by bearings situated on upper and lower parts of the rod, wherein the base of the tower is hollow, having installed on its inside an electromechanical mechanism for selecting weights, including an electric motor, at least a belt, and at least a pulley, mounted by bearing on a shaft fixed to the lower face of the base, collinearly to the center of the rod and the screw, the pulley having in the upper part, a selective engagement mechanism with the lower end of the screw to actuate only when the rod is totally lowered, with the plates resting on the base of the tower.
