Abstract
Abstract A foot-operated exercising device comprises a frame having a longitudinally-extending frame bar terminating at its opposite ends in a pair of transversely-extending frame legs for supporting the frame bar on a horizontal surface, and a pair of foot pedals rotatably mounted on the frame bar about a horizontal, transversely-extending axis. The device further includes a pair of variable-length arms pivotably mounted to one of the frame legs about vertical axes to permit pivotting the arms to an operable position extending at a desired angular relationship axially behind the frame legs, or to a non-operable position in folded relationship with respect to the frame legs.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
149 words
A foot-operated exercising device including a frame having a longitudinally-extending frame bar terminating at its opposite ends in a pair of transversely-extending frame legs for supporting the frame bar on a horizontal surface during use of the device, and a pair of foot pedals rotatably mounted on the frame bar about a horizontal, transversely-extending axis; characterized in that said device further includes a pair of variable-length arms pivotably mounted to one of said transversely-extending frame legs, each of said arms being pivotable about a respective vertical axis to said one frame leg such that said arms may be pivoted to an operable position behind said one frame leg on the side thereof opposite to the other frame leg or to a non-operable position in folded relationship with respect to said frame legs; each of said arms including means at the ends thereof for anchoring same by an external device.
Claim 2
Dependent Claim
149 words
A foot-operated exercising device including a frame having a longitudinally-extending frame bar terminating at its opposite ends in a pair of transversely-extending frame legs for supporting the frame bar on a horizontal surface during use of the device, and a pair of foot pedals rotatably mounted on the frame bar about a horizontal, transversely-extending axis; characterized in that said device further includes a pair of variable-length arms pivotably mounted to one of said transversely-extending frame legs, each of said arms being pivotable about a respective vertical axis to said one frame leg such that said arms may be pivoted to an operable position behind said one frame leg on the side thereof opposite to the other frame leg or to a non-operable position in folded relationship with respect to said frame legs; each of said arms including means at the ends thereof for anchoring same by an external device.
Claim 3
Dependent Claim
38 words
The device according to claim 1, wherein said anchoring means at the outer ends of said arms include cup-shaped sockets for receiving the lower ends of a pair of chair legs for stabilizing the device during its use.
Claim 4
Dependent Claim
29 words
The device according to claim 2, wherein said anchoring means at the outer ends of said arms include an in-turned flange formed at the outer end of each arm.
Claim 5
Dependent Claim
34 words
The device according to claim 1, wherein each of said variable-length arms includes telescoping sections for varying the length thereof, and a locking member for locking the telescoping sections together at the desired length.
Claim 6
Dependent Claim
40 words
The device according to claim 1, further including a pair of threaded pins each threaded through a respective lug fixed to said one leg and adapted to engage the inner faces of the pivotable arms for fixing their angular relationship.
Claim 7
Dependent Claim
67 words
The device according to claim 1, further including a disc fixed to said foot pedals to rotate therewith, a pair of friction pads carried on said frame bar and engaging opposite sides of the disc, and a knob mounted on said frame bar and rotatable to vary the force applied by said friction pads against said disc to thereby vary the loading applied to the foot pedals.
Claim 8
Dependent Claim
91 words
The device according to claim 6, wherein said pair of friction pads are carried by links straddling the rotatable disc and received on a pin having a shoulder at one end engageable with one link, said rotatable knob being threaded onto the opposite end of the pin, the device further including a sleeve interposed between the knob and the other of said links such that threading the knob further onto the pin forces said links towards each other to increase the friction applied by their friction pads to the rotatable disc.
Claim 9
Dependent Claim
29 words
The device according to claim 1, wherein said frame further includes a tubular socket supported by the frame bar, and a handle bar removably received in said tubular socket.
Claim 10
Dependent Claim
38 words
The device according to claim 8, wherein said tubular socket is swivelly mounted to said frame bar about a horizontal axis parallel to said frame legs, and said handle bar includes telescoping sections for varying the length thereof.
