Abstract
Abstract The device relates to physical exercise apparatus providing variable resistance to the user has a weight stack movable along a vertical guide and a carriage movable along another guide, the guides being disposed at a predetermined angle to each other and the carriage and the weight stack being connected to each other through a rigid link. The carriage is movable by the user against a variable force dependent on the position of the weight stack in its guide, the angle between the guides and the weight of the stack.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
109 words
Weight training apparatus comprising: a vertical guide; a weight stack engaged with and reciprocally movable along said vertical guide; a second guide inclined at a predetermined angle to said vertical guide; said second guide extending upwardly in a direction inclined away from said vertical guide; a carriage reciprocally movable along said second guide; means for moving said carriage along said second guide; and a rigid link means pivotally connected to said weight stack and to said carriage so that movement of the carriage along said second guide will cause said weight stack to be lifted; said rigid link extending upwardly in a direction inclined away from said vertical guide.
Claim 2
Dependent Claim
109 words
Weight training apparatus comprising: a vertical guide; a weight stack engaged with and reciprocally movable along said vertical guide; a second guide inclined at a predetermined angle to said vertical guide; said second guide extending upwardly in a direction inclined away from said vertical guide; a carriage reciprocally movable along said second guide; means for moving said carriage along said second guide; and a rigid link means pivotally connected to said weight stack and to said carriage so that movement of the carriage along said second guide will cause said weight stack to be lifted; said rigid link extending upwardly in a direction inclined away from said vertical guide.
Claim 3
Dependent Claim
30 words
A weight training device as claimed in claim 1 in which the weight stack comprises an upper weight and a series of individual weights connectable additively to the upper weight.
Claim 4
Dependent Claim
21 words
A weight training device as claimed in claim 1 in which said carriage is movable along said second guide on rollers.
Claim 5
Dependent Claim
54 words
A weight training device as claimed in claim 3 in which said second guide is a bar and said carriage includes two pairs of arms, the arms of each pair extending one to each side of said guide bar and the arms of each pair supporting between them rollers movable along said guide bar.
Claim 6
Dependent Claim
48 words
Apparatus as claimed in claim 1 in which: H=KW wherein: H=the force applied by the user; W=the weight of the weight stack; and ##EQU2## where θ=angle of inclination of said second guide means; and φ=angle of inclination of said rigid link connecting said weight stack and said carriage.
Claim 7
Dependent Claim
63 words
Apparatus as claimed in claim 1 wherein said means for moving said carriage includes first and second links pivotally connected one to the other, said first link having a free end and a foot pedal mounted thereon; said second link being further pivotally connected to said carriage, and third guide means for determining the path of travel of said first and second links.
Claim 8
Dependent Claim
13 words
Apparatus as claimed in claim 6 wherein said third guide means is arcuate.
Claim 9
Dependent Claim
43 words
Apparatus as claimed in claim 6 wherein an angle defined by said second link of said user arm and said rigid link means is variable; and a force required by a user varies increasingly in response to upward movement of said weight stack.
Claim 10
Dependent Claim
170 words
A weight training device comprising: a vertical guide; a weight stack engaged with and reciprocally movable along said vertical guide; a second guide inclined at a predetermined angle to said vertical guide; said second guide extending upwardly in a direction inclined away from said vertical guide; a carriage reciprocally movable along said second guide; a rigid link means pivotally connected to said weight stack and to said second carriage so that movement of the carriage along said second guide will cause said weight stack to be lifted; said rigid link extending upwardly in a direction inclined away from said vertical guide; and a user arm connected to said carriage for moving said carriage along said second guide, the user arm including first and second links pivotally connected one to the other, said first link having a free end and a foot pedal mounted thereon; said second link being further pivotally connected to said carriage, and third guide means for determining the path of travel of said first and second links.
Claim 11
Dependent Claim
170 words
A weight training device comprising: a vertical guide; a weight stack engaged with and reciprocally movable along said vertical guide; a second guide inclined at a predetermined angle to said vertical guide; said second guide extending upwardly in a direction inclined away from said vertical guide; a carriage reciprocally movable along said second guide; a rigid link means pivotally connected to said weight stack and to said second carriage so that movement of the carriage along said second guide will cause said weight stack to be lifted; said rigid link extending upwardly in a direction inclined away from said vertical guide; and a user arm connected to said carriage for moving said carriage along said second guide, the user arm including first and second links pivotally connected one to the other, said first link having a free end and a foot pedal mounted thereon; said second link being further pivotally connected to said carriage, and third guide means for determining the path of travel of said first and second links.
Claim 12
Dependent Claim
13 words
Apparatus as claimed in claim 9 wherein said third guide means is arcuate.
Claim 13
Dependent Claim
48 words
Apparatus as claimed in claim 9 in which: H=KW wherein: H=the force applied by the user; W=the weight of the weight stack; and ##EQU3## where θ=angle of inclination of said second guide means; and φ=angle of inclination of said rigid link connecting said weight stack and said carriage.
Claim 14
Dependent Claim
43 words
Apparatus as claimed in claim 9 wherein an angle defined by said second link of said user arm and said rigid link means is variable; and a force required by a user varies increasingly in response to upward movement of said weight stack.
