Pedal actuated exercising device with adjustable load control

Claim 2

An exercising device, the combination comprising a stationary frame assembly having handlebars and seating means, a rotatable wheel carried by said frame assembly, pedal actuated means for rotating said wheel, belt means engaging a portion of said wheel for placing a load thereon, load control means adjustably carried by said frame assembly and engaging said belt means for varying the load applied thereby to said wheel, said load control means comprising a member engaging said belt means and a manually movable element including an eccentric disc for positioning said member in response to movement of said manually movable element, and retaining means biasing said disc and retaining said load control means in a predetermined adjusted position whereby said belt means applies a predetermined fixed load corresponding to the predetermined adjusted position.

Claim 3

The invention as recited in claim 1 wherein said retaining means comprises a spring exerting a biasing force on said disc.

Claim 4

The invention as recited in claim 2 wherein said spring is a coil spring mounted in compression against said disc.

Claim 5

In an exercising device, the combination comprising a frame assembly adapted to remain stationary on a supporting surface, handlebars and seating means on said frame assembly, a rotatable wheel on said frame assembly, actuating means for rotating said wheel, belt means adapted to engage a portion of said wheel for placing a load thereon during its rotation, load control means movable between a plurality of controlling positions for varying the load applied by said belt means to said wheel, said load control means including a rotatable eccentric disc and a member carried by said frame assembly and being movable in response to movemenT of said disc for selecting the load applied by said belt means, said member for selecting the load including an idler arm having a cam follower engaging said eccentric disc and an idler roller engaging said belt means, a mounting assembly supporting said load control means on said frame assembly including a shaft element carrying said disc, and retainer means carried by said mounting assembly and being in engagement with said load control means and retaining the same in its selected controlling position whereby a fixed load is applied by said belt means for such selected controlling position.

Claim 6

In an exercising device, the combination comprising a frame assembly adapted to remain stationary on a supporting surface, handlebars and seating means on said frame assembly, a rotatable wheel on said frame assembly, actuating means for rotating said wheel, belt means adapted to engage a portion of said wheel for placing a load thereon during its rotation, load control means movable between a plurality of controlling positions for varying the load applied by said belt means to said wheel, said load control means including a rotatable eccentric disc and a member carried by said frame assembly and being movable in response to movemenT of said disc for selecting the load applied by said belt means, said member for selecting the load including an idler arm having a cam follower engaging said eccentric disc and an idler roller engaging said belt means, a mounting assembly supporting said load control means on said frame assembly including a shaft element carrying said disc, and retainer means carried by said mounting assembly and being in engagement with said load control means and retaining the same in its selected controlling position whereby a fixed load is applied by said belt means for such selected controlling position.

Claim 7

The invention as recited in claim 4 wherein said retainer means is disposed on said shaft element and biases said disc in its selected position.

Claim 8

The invention as recited in claim 5 wherein said retainer means comprises a coil spring mounted in compression against said disc.

Claim 9

The invention as recited in claim 6 wherein said belt means includes a flexible belt having opposite ends joined by a tension spring.

Claim 10

The invention as recited in claim 7 wherein said flexible belt engages said idler roller.

Claim 11

The invention as recited by claim 8 wherein a winding drum is rotatably carried by said shaft and said flexible belt in fixed to said winding drum for rotating the same in response to tension from said flexible belt.

Claim 12

The invention as recited in claim 9 wherein said pendulum means is suspended from said winding drum to compensate for torque during movement thereof.

Claim 13

The invention as recited in claim 10 wherein a fixed scale is carried by said shaft and said pendulum serves as a movable indicator for said fixed scale.
