Abstract
Abstract A selectively configurable exercise machine includes a vertical frame in an inverted V-shape which is coupled to a horizontal weight platform. The weight platform includes a free-swinging end for carrying the weights and an opposite end which forms a double pivotal connection with the vertical frame. The double pivotal connection is formed by a pair of rocker arms pivotally connected on one end to the weight platform and pivotally connected on the opposite end of the rocker arm to the vertical frame. The weight platform is suspended by multiple pulleys threaded with a single flexible line which may be held by the user for performing a variety of one and two-handed exercises.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
188 words
An exercise apparatus for lifting weights using a flexible line having a first end and a second end, which ends are manually manipulable, either separately or simultaneously, said apparatus comprising: a vertical frame having an upper and lower portion and a horizontally-extending base; a weight platform perpendicular to said vertical frame having a free-swinging end configured for carrying said weights and an opposite end disposed adjacent the lower portion of said frame; a plurality of upper pulleys coupled to the upper portion of said vertical frame; connection means pivotally connecting the lower portion of said vertical frame to said opposite end of said weight platform, whereby the free-swinging end of said weight platform will remain in a generally vertical plane below said upper pulleys during normal swinging movement of said platform and the pivotable opposite end being attached to the frame at a position more remote from the user than the free end of the platform; and an opposing lift pulley attached to the free-swinging end of said weight platform, the intermediate portion of said flexible line being woven through said upper pulleys and said opposing lift pulley.
Claim 2
Dependent Claim
188 words
An exercise apparatus for lifting weights using a flexible line having a first end and a second end, which ends are manually manipulable, either separately or simultaneously, said apparatus comprising: a vertical frame having an upper and lower portion and a horizontally-extending base; a weight platform perpendicular to said vertical frame having a free-swinging end configured for carrying said weights and an opposite end disposed adjacent the lower portion of said frame; a plurality of upper pulleys coupled to the upper portion of said vertical frame; connection means pivotally connecting the lower portion of said vertical frame to said opposite end of said weight platform, whereby the free-swinging end of said weight platform will remain in a generally vertical plane below said upper pulleys during normal swinging movement of said platform and the pivotable opposite end being attached to the frame at a position more remote from the user than the free end of the platform; and an opposing lift pulley attached to the free-swinging end of said weight platform, the intermediate portion of said flexible line being woven through said upper pulleys and said opposing lift pulley.
Claim 3
Dependent Claim
38 words
The apparatus of claim 1 wherein said connection means includes a double linkage comprised of a pair of arms, each arm being rotatably coupled at one end to said frame and at the opposing end to said platform.
Claim 4
Dependent Claim
17 words
The apparatus of claim 1 wherein said weight is coupled to said platform near said free-swinging end.
Claim 5
Dependent Claim
25 words
The apparatus of claim 3 where said arms are of sufficient length such that said opposing lift pulley is positioned vertically beneath said upper pulleys.
Claim 6
Dependent Claim
32 words
The apparatus of claim 4 where said range of operating orientations includes an angular inclinations of the plane of said platform with respect to the vertical of approximately 5° to 125° degrees.
Claim 7
Dependent Claim
32 words
The exercising machine of claim 1 further including an adjustable bench disposed on said horizontally extending base of said frame and slideable thereon for selective displacement with respect to of said frame.
Claim 8
Dependent Claim
41 words
The exercise apparatus of claim 1 further including a pair of lower pulleys coupled to the lower portion of said frame wherein said flexible line is woven through said upper pulleys, said opposing lift pulley, and said pair of lower pulleys.
Claim 9
Dependent Claim
193 words
The exercise apparatus of claim 7 wherein said frame includes at least two flanges connected to the lower portion of said vertical frame and said lower pulleys including two single-sheaved pulleys, each pulley coupled to a corresponding one of said flanges, said line being led through one of said lower pulleys up to one of said plurality of upper pulleys, through said one upper pulley and downward to said lift pulley, said lift pulley being a double-sheaved pulley, said line then being led back up to a center, single-sheaved, upper pulley and downward through said double sheaved lift pulley, said line continuing upward from said double sheaved lift pulley to third, single-sheaved, upper pulley and downward to and through the remaining single-sheaved, lower pulley, whereby said flexible line is woven through said pulleys such that extension of one end of said line requires withdrawal of the opposing end of said line if said lift pulley is maintained in an approximately stationary position, and such that when both ends of said line are extended from said frame, said platform is caused to pivot around said connection means and is raised by said lift pulley.
Claim 10
Dependent Claim
59 words
The exercise machine of claim 7 wherein said upper and lower pulleys are selectively coupled to said lower and upper portions of said frame, respectively, by attachment through a selected one of plurality of mounting holes defined in said lower and upper portions of said frame, whereby the range of exercise possible with said exercising machine are substantially increased.
