<p>A load selector (1), in particular for an exercise machine wherein the load to be used in an exercise is variable and is determined by the value of the sum of a plurality of weight elements (3) which are associated, through related fastening means, to a tugging element (40) comprising a rod (4) kinematically connected to appropriate means able to exert a force by a user (41); the weight elements (3) can be stacked on top of one another and present corresponding holed portions (30) able to define a channel for the rod (4); the rod (4) presents, along its own longitudinal development, i.e. along the direction of development of the aforesaid channel, cross sections of alternatively differentiated value to define thereby a series of notches or tapers (45); the fastening means comprise a plurality of coupling elements (2), positioned in correspondence with each of the weight elements (3), and movable between a first position wherein they do not interact with the rod (4) and a second position wherein they do interact with the rod (4) itself, in correspondence with one of the notches or tapers (45), for the determination of the load. <IMAGE></p> |
