A weight assembly for an exercising apparatus is provided and includes a pair of vertically spaced superposed upper and lower generally horizontal panel members each including four openings formed therethrough spaced about a central area of the panel member. The two sets of four openings are at least generally registered and four upstanding elongated flexible tension member sections have their lower ends slidably received through corresponding openings in the panel members and the lower terminal ends of the tension member sections are anchored through the openings in the lower panel member. The upper ends of the tension members are upwardly convergent and are anchored relative to an anchor member. Variable weight value structure is supported on the lower panel member below the upper panel member and the tensioning of the tension member sections and the weight of the upper panel member tend to cause the variable weight value structure to be clamped between the upper and lower panel members. Further, novel structure is provided for anchoring the tension member sections to the anchor member and the latter to a pair of tension member sections trained over a pair of pulleys.
In combination with a horizontal first structure and a second structure elevated above said first structure, pulley means in anchored relation to said second structure, abutment means on said first structure spaced normal from an upstanding plane containing said pulley means and against which a person disposed on said first structure may abut at least one portion of his body to prevent sliding of said person relative to said first structure toward said plane, first elongated flexible tension member means having its midportion passed over said pulley means, a first end portion depending downwardly from said pulley means and a second end portion extending downwardly from said pulley means toward said first structure at an incline away from said plane, gravity weight means of predetermined selected value supported from a lower portion of said first end portion, anchor means supported from a lower portion of said second end portion, a pulley assembly supported from said anchor means, second elongated flexible tension member means having its longitudinal midportion guidingly engaged over said pulley assembly and including opposite end body limb engageable portions for engagement by arm and/or leg limbs with forces exerted by the limbs engaged therewith in opposition to the predetermined selected gravity weight value of said weight means supported from said lower portion of said first end portion of said first tension member means, said weight means including an anchor member to which said first end portion is anchored, a pair of superposed upper and lower generally horizontal panel members provided with four openings therethrough spaced about central areas of said panel members and with the openings in said panel members at least generally registered, four elongated upstanding flexible tension member sections having their lower ends slidingly received through corresponding openings in said panel members and anchored through the openings in the lower panel member, the upper ends of said tension member sections being upwardly convergent and anchored relative to said anchor member, and variable weight structure supported on said lower panel member and below the upper panel member.
In combination with an elevated support structure, first pulley means supported from said support structure, first elongated flexible tension member means guidingly engaged over said first pulley means for lengthwise back and forth shifting relative to said first pulley means and including a depending first end portion from which a gravity weight assembly is suspended, said weight assembly being of predetermined selected value, said second pulley means anchored relative to the second end of said first tension member means, second elongated flexible tension member means guidingly engaged over said second pulley means, and body limb engageable portions carried by the opposite ends of said second elongated tension member means, said body limb engageable portions being adapted to be engaged by arm/leg limbs with forces exerted by the limbs engaged therewith in opposition to the predetermined gravity weight value of said weight suspended from said first end portion of said first tension member means, said weight assembly means including an anchor member anchored relative to said depending first end portion, a pair of superposed upper and lower generally horizontal panel members provided with four openings therethrough spaced about central areas of said panel members and with the opening in said panel members at least generally registered, four elongated upstanding flexible tension member sections having their lower ends slidingly received through corresponding openings in said panel members and anchored through the openings in the lower panel member, the upper ends of said tension member sections being upwardly convergent and anchored relative to said anchor member, and variable weight structure supported on said lower panel member and below the upper panel member.
