Abstract

A home gym system (100) is provided for performing weight lifting exercises with a load resistance (160, 164) coupled to a cable (132). The home gym system (100) includes a main frame (110) to which is pivotedly coupled at least one extension frame (120). A guide arm assembly (130) is slidingly coupled to frame extension (120) and vertically displaceable thereon. Vertical displacement of guide arm assembly (130) is made substantially effortless by a counter weight system (140) coupled to guide arm assembly (130) by a flexible member (141). Counter weight system (140) includes a floating pulley system (145) to compensate for changes in cable path length which result from the vertical displacement of guide arm assembly (130). Additionally, guide arm assembly (130) includes a system for increasing the load resistance by varying the mechanical advantage of the cable system. The change in mechanical advantage is accomplished by coupling the releasable coupling (192) at the exit end of cable (132) to the pivotable arm member (172) allowing the cable to be withdrawn from guide arm assembly (130) by displacement of both the exit end of cable (132) and a portion of cable (132) from a position intermediate a first pulley assembly (134) by a second pulley assembly (136), when pivotal arm member (172) is displaced.

Dependent claims

A multi-exercise system for performing weight lifting exercises with a load resistance coupled to a cable, comprising:

a. a vertically extended stationary main frame;
b. a plurality of weights selectively coupled to one end of said cable for defining said load resistance disposed within said main frame;
c. at least one movable frame extension, said frame extension being pivotedly coupled to said main frame on one side thereof;
d. guide arm means vertically displaceable on said frame extension for directing an opposite end of said cable, said guide arm means includes (1) a first arm member slidingly coupled to said frame extension and extending longitudinally therefrom, and (2) first pulley means coupled to said first arm member for guiding said cable substantially parallel to said first arm member said first pulley means including at least a first and second pair of vertically opposing first pulley wheel members disposed on said first arm member for capturing said cable therebetween, (3) a second arm member pivotedly coupled at one end to a first end of said first arm member, and (4) second pulley means fixedly coupled to said second arm member for coupling said cable to said second arm member relative to said first arm member transmits an applied force to said load resistance;
e. counter weight means coupled to said guide arm means for (1) substantially counterbalancing said guide arm means, and (2) releasably locking said guide arm means in a selected vertical positional location;
and
f. actuator means coupled to said opposing end of said cable and engageable by a portion of a user's body for applying a force thereto.

A multi-exercise system for performing weight lifting exercises with a pair of load resistances each coupled to one of a pair of cables, comprising:

a. a vertically extended stationary main frame defined by a pair of opposing side members;
b. a plurality of first weight members disposed within said main frame and selectively coupled to one end of one of said pair of cables for defining at least a portion of said load resistance;
c. a plurality of second weight members disposed within said main frame and selectively coupled to one end of the other of said cables for defining at least a portion of said load resistance;
d. a pair of movable frame extensions, each of said pair of frame extensions being pivotedly coupled to one of said opposing side members;
e. guide arm means vertically displaceable on each of said frame extensions for directing a respective opposing end of each of said cables, said guide arm means includes (1) a first arm member slidingly coupled to said frame extension and extending longitudinally therefrom, (2) first pulley means coupled to said first arm member for guiding said cable substantially parallel to said first arm member, said first pulley means including at least a first and second pair of vertically opposing first pulley wheel members disposed on said first arm member for capturing said cable therebetween, (3) a second arm member pivotedly coupled at one end to a first end of said first arm member, and (4) second pulley means fixedly coupled to said second arm member for coupling said cable to said second arm member, whereby displacement of said second arm member relative to said first arm member transmits an applied force to said load resistance;
and,
f. actuator means coupled to said opposing ends of said pair of cables and engageable by a portion of a user's body for applying a force thereto.
