Abstract
Abstract A portable exercise cycle which is convertible between an arm exerciser and a leg exerciser. A flywheel assembly is journaled in an upright frame which is mounted on an T-shaped base. Flywheel tension is adjustable. Two L-shaped lever members are mounted on opposite sides of the frame for manually rotating the flywheel. When used as a leg exerciser, the machine is placed on the floor and pedals are attached to the lever members. When used as an arm exerciser the machine is clamped to a table top, and handgrips are attached to the lever members. Limited grip handgrips are provided for those with limited gripping ability. An electronic display unit displays elapsed time, speed, and equivalent distance traveled.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
A stationary seatless bicycle-like assembly having a base and a frame; rotation means including a transverse axle journaled in the frame and pedals rotatably mounted on each end of the axis, and means for varying the resistance of said rotational motion of the axle including a tension control wherein the improvement comprises: a front support rod for supporting said rotation means and said pedals on said base and a vertically telescoping rear support rod extending upwardly from the base; a bar slidably secured to the telescoping rear support rod for horizontal movement; a forehead rest secured to the bar and extending outwardly therefrom, said rest being adjustable both horizontally and vertically by means of said vertically telescoping rear support rod and horizontally slidable bar; and a clamp mounted on the base for securing the base to a tabletop.
Claim 2
Dependent Claim
138 words
A stationary seatless bicycle-like assembly having a base and a frame; rotation means including a transverse axle journaled in the frame and pedals rotatably mounted on each end of the axis, and means for varying the resistance of said rotational motion of the axle including a tension control wherein the improvement comprises: a front support rod for supporting said rotation means and said pedals on said base and a vertically telescoping rear support rod extending upwardly from the base; a bar slidably secured to the telescoping rear support rod for horizontal movement; a forehead rest secured to the bar and extending outwardly therefrom, said rest being adjustable both horizontally and vertically by means of said vertically telescoping rear support rod and horizontally slidable bar; and a clamp mounted on the base for securing the base to a tabletop.
Claim 3
Dependent Claim
64 words
The invention of claim 1 further comprising: a padded grip secured to and extending outwardly from the rotation means, said grip being independently rotatable; and a protection plate secured toward the end of the grip nearest the rotation means, said protection plate rotating with said grip, said protection plate being of sufficient size to block the hand from contacting the rotation means during operation.
Claim 4
Dependent Claim
34 words
The invention of claim 2 wherein said protection plate further comprises a plurality of openings; and cylinders secured within said openings, said cylinders aligned to secure the user's hand in relation to said grip.
Claim 5
Dependent Claim
149 words
A stationary bicycle-like assembly having a base and frame; rotation means including a transverse axle journaled in the frame and cranks rotatably mounted on each end of the axle, and means for varying the resistance of said rotational motion of the axle including a tension control wherein the improvement comprises: padded gripping means secured to and extending outwardly from the rotation means, said gripping means being independently rotatable; a protection plate secured toward the end of the gripping means nearest the rotation means, said protection plate rotating with said gripping means and thereby preventing contact between the user and the rotation means during operation, said protection plate having openings therein and cylinders secured within said openings and forming a substantially triangular shape with said gripping means, said cylinders being movable vertically toward and away from the gripping means in order to secure the user's hand against said gripping means.
Claim 6
Dependent Claim
149 words
A stationary bicycle-like assembly having a base and frame; rotation means including a transverse axle journaled in the frame and cranks rotatably mounted on each end of the axle, and means for varying the resistance of said rotational motion of the axle including a tension control wherein the improvement comprises: padded gripping means secured to and extending outwardly from the rotation means, said gripping means being independently rotatable; a protection plate secured toward the end of the gripping means nearest the rotation means, said protection plate rotating with said gripping means and thereby preventing contact between the user and the rotation means during operation, said protection plate having openings therein and cylinders secured within said openings and forming a substantially triangular shape with said gripping means, said cylinders being movable vertically toward and away from the gripping means in order to secure the user's hand against said gripping means.
Claim 7
Dependent Claim
166 words
A stationary bicycle-like assembly having a base and frame; rotation means including a transverse axle journaled in the frame and cranks rotatably mounted on each end of the axle, and means for varying the resistance of said rotational motion of the axle including a tension control wherein the improvement comprises: padded gripping means secured to and extending outwardly from the rotation means, said gripping means being independently rotatable; a protection plate secured toward the end of the gripping means nearest the rotation means, said protection plate rotating with said gripping means and thereby preventing contact between the user and the rotation means during operation, said protection plate having elongate openings therein; a wrist plate adapted for movable securement within said elongate openings, said wrist plate having adjacent slots therein; and a pair of rods securable within said slots whereby the combined movement of the plate and the rods enables the user to secure the wrist between said rods while the hands rest on the gripping means.
