Fitness center work-out station with electromechanical control of end of stroke position

Abstract

A fitness center work-out station with electromechanical control of the end of stroke position, including a base, from which there arises a structure where there is fastened a seat, a back rest, arms for action by the user, pulley for connecting the arms, and a steel cable which descends to the level of the base passing through a compensating pulley and following on horizontally to the opposite end of the base where there is a vertical tower where there are stacked the weights, where the end of the steel cable is connected. The base is provided with a contour structure, with two centrally supporting frame rails of the upper structure and a compensating pulley pivoted between the pair of frame rails and at the base of the structure.

1 . A fitness center work-out station with electromechanical control of the end of stroke position, comprising: a base, from which there arises a structure to which there are fastened seat, back rest, arms for action by the user, a first pulley for connecting the arms, and a steel cable which descends to the level of the base passing through a compensating pulley and following on horizontally to the opposite end of the base where there is a vertical tower where there are stacked a stack of weights, where the end of the steel cable is connected, wherein the base is provided with a contour structure, with two centrally supporting frame rails of the upper structure and the compensating pulley pivoted between the pair of frame rails and at the base of the structure; with second and third pulleys, with vertical shafts and with a space between them where there is inserted a fourth pulley mounted on the rod of a linear actuator fixed to the structure and its frame rails, the steel cable passing between the compensating pulley and the exit of the cable, by the second, third, and fourth pulleys, being fastened to the rod of the linear actuator a linear sensor to inform relative positions of the rod and memorize them. 
     
     
         2 . The fitness center work-out station according to  claim 1 , wherein the base presents the horizontal section of the steel cable, intermediarily the compensating pulley and the exit of this steel cable towards the tower, at least, the second and third pulleys, coplanar in relation to each other with their respective vertical shafts distanced apart which allows the provision of the fourth pulley fitted therebetween; and the shaft of the fourth pulley is mounted on the rod of the linear actuator, which is mounted on the structure of the base. 
     
     
         3 . The fitness center work-out station according to  claim 1 , wherein the second and third pulleys, the fourth pulley, the rod which make up the linear actuator and also the linear sensor are part of a combination mounted on a mounting base attached to the base and interplaced between weights tower and station, forming an extension of the base. 
     
     
         4 . The fitness center work-out station according to  claim 1 , wherein the linear actuator, which is driven by a station command panel, is authorized to operate when a sensor of the tower informs that the stack of weights is on the base of the tower, without tightening the steel cable. 
     
     
         5 . The fitness center work-out station according to  claim 4 , further comprising a tension sensor of the steel cable, with the stack of weights of the tower on the base, to recognize slack in the steel cable, and warn the station command panel to drive the linear actuator until the slack disappears.
