Adjustable resistance exercising apparatus

A user actuated exercising apparatus comprising:

• means for rotatably supporting a disc;
• a braking pad mounted to frictionally engage said disc and provide a braking force to said disc;
• manually actuated means for varying the magnitude of said braking force by said pad on said disc;
• user operated means for providing rotation of said disc against said variable braking force,
• said braking pad being engageable with a first disc side at the disc periphery;
• a second braking pad spaced from and oppositely supported to said braking pad and engageable with said second disc side;
• said manually actuated means comprising spaced means to vary the spacing between said pads to vary the braking force on said disc;
• a first disc plate carrying at one end thereof said braking pad;
• a second disc plate carrying at one end thereof said second braking pad;
• a spring being mounted to resiliently support said second plate relative to said first plate;
• said spacing means varying the spacing between said plates relative one another against the force of said spring to vary the braking force applied by said pads to said disc,
• said manually actuated means comprises a rotatably mounted manually operated pointer, an elongate threaded member extending through said plates and held against rotation relative to said first and second disc plates;
• a nut in threaded engagement with said threaded member and operable against one of said plates on rotation relative thereto;
• a link assembly being attached to said pointer and said nut to rotate said nut upon rotation of said pointer to thereby vary the braking force on said disc.
