Claim 5

The combination set forth in claim 3 wherein said sheaves are mounted on a common shaft.

Claim 6

The combination set forth in claim 4 wherein said spring means comprises a helically wound spring having one end thereof fixed to said shaft and the other end thereof fixed to a support.

Claim 7

The combination set forth in claim 5 including means for varying the tension of said spring.

Claim 8

The combination set forth in claim 6 including indicia means for indicating the relative tension on said spring.

Claim 9

The combination set forth in claim 1 including means defining a vertical surface adjacent said platform, said platform having antifriction means thereon engaging said vertical surface to assist in guiding the platform in its vertical movement.

Claim 10

The combination set forth in claim 1 wherein said means yieldingly urging said foot platform upwardly comprises cables connected at one end to said platform, sheaves rotatably mounted about generally horizontal axes on said upper ends of said vertical members around which said cables are wound, and spring means tending to rotate said sheaves in a direction to move said platform upwardly

Claim 11

The combination set forth in claim 9 including a horizontal beam on the upper ends of said vertical members, and a horizontal shaft rotatably mounted thereon, said sheaves being mounted on said shaft.

Claim 12

The combination set forth in claim 10 wherein said spring means comprises a helically wound spring having one end thereof fixed to said shaft and the other end thereof fixed to said horizontal beam.

Claim 13

The combination set forth in claim 11 including means for varying the tension of said spring.

Claim 14

The combination set forth in claim 12 including indicia means for indicating the relative tension on said spring.

Claim 15

In an exercising apparatus, the combination comprising a frame including a pair of vertical members adapted to be fixed to a wall, a horizontal bar extending between said vertical members and adapted to be grasped by a person performing exercise, a foot platform, means adjacent the upper eNds of said vertical member above said platform for supporting said foot platform for vertical movement, telescoping means for stabilizing said platform in its vertical movement extending between said frame and said foot platform, biasing means mounted above said bar and yieldingly urging said foot platform upwardly.

Claim 16

In an exercising apparatus, the combination comprising a frame including a pair of vertical members adapted to be fixed to a wall, a horizontal bar extending between said vertical members and adapted to be grasped by a person performing exercise, a foot platform, means adjacent the upper eNds of said vertical member above said platform for supporting said foot platform for vertical movement, telescoping means for stabilizing said platform in its vertical movement extending between said frame and said foot platform, biasing means mounted above said bar and yieldingly urging said foot platform upwardly.

Claim 17

The combination set forth in claim 14 wherein said telescoping means for stabilizing said foot platform for vertical movement comprises a telescoping member fixed to said platform and a telescoping member fixed to said vertical members.

Claim 18

The combination set forth in claim 14 including means defining a vertical surface adjacent said platform, said platform having antifriction means thereon for engaging said vertical surface to assist in guiding the platform in its vertical movement.

Claim 19

In an exercising apparatus, the combination comprising a horizontal bar supported between two vertical members for performing chinning exercises, a foot platform below said bar with biasing means for normally urging said platform in a vertical direction towards said bar, and means for guiding said platform in a vertical direction comprising rollable antifriction means on said platform and resilient strips mounted along the bar supporting vertical members for engaging said rollable antifriction means.

Claim 20

In an exercising apparatus, the combination comprising a horizontal bar supported between two vertical members for performing chinning exercises, a foot platform below said bar with biasing means for normally urging said platform in a vertical direction towards said bar, and means for guiding said platform in a vertical direction comprising rollable antifriction means on said platform and resilient strips mounted along the bar supporting vertical members for engaging said rollable antifriction means.
