Abstract An improved exercising machine, particularly for exercising the arm muscles while the user stands upon a base having a sheave about which a substantially inextensible flexible cable or rope is entrained, the cable having hand grip assemblies with a unique quick release fastening means for the handgrip assemblies to give infinitely adjustable cable lengths and comprising a body having a longitudinal bore therethrough and a transverse vent. A return cable portion and the adjacent cable portion extends through the bore. A loop in the return cable portion forms a loop extending outwardly from the vent and the terminal portion of the cable extends through the loop. The cable is calibrated for precise repeatable adjustment of the effective length of the cable. The ready adjustability of the exerciser makes it particularly useful by different members of a family, for example, and for changes between isometric and isotonic exercises. For storage purposes the base is formed with recesses in its ends around which the cable is sheaved.
Improvements in an exercising machine or the like having a releasibly anchored sheave and a flexible cable entrained around said sheave so that the two end portions of the cable can be separately pulled by the two hands of the user, said improvements comprising: handgrip-stirrup assemblies on the end portions of said cable, each assembly including: a returned cable portion defining a loop; quick-release securing means adjustably fastening said returned cable portion to an adjacent portion of the cable comprising a body having a bore therethrough and a vent leading from said bore to the exterior of said body; said returned cable portion and said adjacent portion of the cable extending through said bore and the former having a diverted loop portion thereof extending outwardly through said vent with a terminal portion of the cable introduced into said diverted loop portion to constitute a simple knot easily untied by an intentional pull on said terminal portion.

Claim 3
Dependent Claim
28 words
Improvements according to claim 1 wherein said cable has spaced markings thereon enabling precise and repeatable adjustment of the handgrip-stirrup assemblies for different effective lengths of the cable.
Claim 4
Dependent Claim
60 words
Improvements according to claim 1 including a base upon which said sheave is attached; said base being an elongated block of form-retaining material capable of being held in place by the user standing thereon; and said base havIng opposed arcuately recessed portions to receive and hold said cable when superficially reeled thereon for storage and shipment of the exercising machine.
