ABSTRACT:
An exercise machine weight guide including an uppermost plate with a centrally disposed mounting hole. The mounting hole is designed to accommodate a threaded plug and a securing plug. A weight post with one threaded end and a number of apertures disposed along its length is inserted through the opening of the uppermost plate. The threaded plug has internal threads for securing over the threaded end of the weight post. The securing plug is positioned over the threaded plug and engages, of a corresponding set of threads, with the threads located within the mounting hole. A number of weights are disposed below the uppermost plate. The lower surface of each weight has a groove which allows a connector pin to pass under the weight and through an aperture of the weight post. The threaded plug is rotated to tighten the assembly to form a single mass of weight and securing plug is rotated to tighten against the threaded plug locking the threaded plug in place. To change the weight, the procedure is reversed.
