Abstract:
1. An athletic exerciser pulling apparatus, comprising in combination: (a) a plurality of spring housing assemblies; each spring housing assembly comprising: a multiplicity of circular, constant force spring assemblies; an elongate housing member made of molded hard plastic and including a cylindrical bore having a longitudinal axis extending from one end to a distal end, said bore being sized in diameter to permit stacking said spring assemblies therein; a first end cap and a second end cap made of molded hard plastic for capping both open ends of said housing member; and means for manually selected engagement of one or more said spring assemblies by a user, as a spring resisting force; (b) a pulley wheel assembly comprising a rigid plastic, tray-like holder, a metal pulley wheel that fits in said holder, and a pull handle that is attached to a cord which is wound around said pulley wheel; said holder being shaped and sized to fit against a flat surface of said second end cap, and including a semicircular shaped deep cavity in which said pulley wheel is seated, with part of said pulley wheel extending over an open side edge of said holder, said holder including a fourth hole for allowing passage of a central shaft; (c) means for clamping said spring housing assemblies and said pulley wheel assembly together in a column, when said pulley wheel assembly is held between the second end caps of two spring housing assemblies; said pulley wheel assembly being oriented so that said pulley wheel in said holder extends with its pull cord in the open space created between the ends of said spring housing assemblies at said control face of said apparatus; and, (d) an elongate metal shaft having a longitudinal groove extending from one end of said shaft to a distal shaft end, said shaft being disposed along the longitudinal axis of the bores in said spring housing assemblies and through the hub of said pulley wheel, engaging the hubs of all rotatable components that are contained in said apparatus;
