Abstract
Abstract An exercise machine for restoring lost movement to joints and muscles includes a base to which a chair upon which the user is seated may be mounted, to prevent the machine from tipping, and includes a vertical standard mounting a rotatable handlebar assembly and a crank assembly. The handlebar assembly includes a sloping stem rotatable on the vertical standard and handlebars rotatable on the upper sloping end of the stem, whereby propelling the handlebars about for a circular path of the stem upper end provides a wide range of movement to the arms and upper torso. The crank assembly is made up of upper and lower bicycle-type crank mechanisms, for the arms and legs, coupled by a V-belt so that strong, readily moved legs may be utilized to restore movement to arms whose range of movement is impaired, or vice-versa.

Claim 1
Independent Claim
290 words
An exercise machine by which persons may exercise while seated on seating means having a floor support portion, comprising A. a substantially vertical standard, B. a handlebar mechanism including a stem member mounted rotatably at the upper end of the vertical standard on a vertical axis and sloping upward therefrom, ending in a sloping upper end, and outward extending handlebars, mounted rotatably along a sloping axis at the upper end of the stem member, C. a crank mechanism including a support arm mounted on the vertical standard at a point below its upper end and sloping upward therefrom, means to adjust the angle of the arm relative to the standard, a lower crank assembly mounted adjacent to the lower end of the arm, the lower crank assembly having foot pedals, an upper crank assembly mounted adjacent to the upper end of the arm, the upper crank assembly having handgrips, and means operable between the lower and upper crank assemblies to cause rotation of one crank assembly on rotation of the other, the exercise machine further comprising D. a base assembly including a base having means to support the vertical standard either in a first angular position, in which the crank assembly is to be utilized, or in a second angular position 180° removed therefrom, and socket means on the base remote from the support means and positioned genrally in the direction of said first angular position, to accept the floor-support portion of the seating means, whereby the weight of a person seated on the seating means prevents the exercise machine from tipping, and such person may utilize the crank assembly for exercising the arms or legs or both, or alternately utilize the handlebar mechanism without interference from the crank mechanism.
Claim 2
Dependent Claim
290 words
An exercise machine by which persons may exercise while seated on seating means having a floor support portion, comprising A. a substantially vertical standard, B. a handlebar mechanism including a stem member mounted rotatably at the upper end of the vertical standard on a vertical axis and sloping upward therefrom, ending in a sloping upper end, and outward extending handlebars, mounted rotatably along a sloping axis at the upper end of the stem member, C. a crank mechanism including a support arm mounted on the vertical standard at a point below its upper end and sloping upward therefrom, means to adjust the angle of the arm relative to the standard, a lower crank assembly mounted adjacent to the lower end of the arm, the lower crank assembly having foot pedals, an upper crank assembly mounted adjacent to the upper end of the arm, the upper crank assembly having handgrips, and means operable between the lower and upper crank assemblies to cause rotation of one crank assembly on rotation of the other, the exercise machine further comprising D. a base assembly including a base having means to support the vertical standard either in a first angular position, in which the crank assembly is to be utilized, or in a second angular position 180° removed therefrom, and socket means on the base remote from the support means and positioned genrally in the direction of said first angular position, to accept the floor-support portion of the seating means, whereby the weight of a person seated on the seating means prevents the exercise machine from tipping, and such person may utilize the crank assembly for exercising the arms or legs or both, or alternately utilize the handlebar mechanism without interference from the crank mechanism.
Claim 3
Dependent Claim
93 words
An exercise machine comprising a base, a substantially vertical standard extending upward from the base, a stem member mounted rotatably at the upper end of the vertical standard on a vertical axis and sloping upward therefrom, ending in a sloping upper end, and further comprising handlebars mounted rotatably to the sloping upper end of the stem member, the handlebars having outer handgrip portions, whereby the machine may be utilized by grasping the handlebar handgrip portions and so propelling the handlebars about that the upper end of the stem member traces a circular path.
Claim 4
Dependent Claim
93 words
An exercise machine comprising a base, a substantially vertical standard extending upward from the base, a stem member mounted rotatably at the upper end of the vertical standard on a vertical axis and sloping upward therefrom, ending in a sloping upper end, and further comprising handlebars mounted rotatably to the sloping upper end of the stem member, the handlebars having outer handgrip portions, whereby the machine may be utilized by grasping the handlebar handgrip portions and so propelling the handlebars about that the upper end of the stem member traces a circular path.
Claim 5
Dependent Claim
43 words
The exercise machine defined in claim 2, and further comprising a bicycle-type crank assembly supported by the vertical standard below the level of the stem member, the crank assembly having foot pedals, whereby to permit simultaneous exercise of both the legs and arms.
Claim 6
Dependent Claim
87 words
The exercise machine defined in claim 3, and further comprising a support arm extending outward and upward from the vertical standard, a second bicycle-type crank assembly supported adjacent to the outer end of the arm member, the second crank assembly having handgrips, and comprising means, operable between the lower and upper crank assemblies, to cause rotation of one crank assembly on rotation of the other, whereby a strong, readily moved limb may be utilized to impart movement to other weaker limbs whose range of movement is impaired.
Claim 7
Dependent Claim
62 words
The exercise machine defined in claim 2, for use with leg-supported seating furniture upon which a person may be seated during exercise, and further comprising a base for the vertical standard, socket means, on the base, to accept and secure the lower ends of the legs of the seating furniture, whereby the weight of the person prevents the exercise machine from tipping.
Claim 8
Dependent Claim
120 words
An exercise machine comprising a substantially vertical standard, a stem member mounted rotatably at the upper end of the vertical standard and sloping upward and outward therefrom, handlebars mounted rotatably to the upper end of the stem member, the handlebars having outer handgrip portions, a support arm extending slopingly upward from the vertical standard, a first bicycle-type crank assembly, supported by the standard, the first crank assembly having foot pedals, a second bicycle-type crank assembly mounted on the support arm adjacent to its outer end, above the level of the first crank assembly, the second crank assembly having handgrips, means, operable between the lower and upper crank assemblies, to cause rotation of one crank assembly on rotation of the other.
Claim 9
Dependent Claim
120 words
An exercise machine comprising a substantially vertical standard, a stem member mounted rotatably at the upper end of the vertical standard and sloping upward and outward therefrom, handlebars mounted rotatably to the upper end of the stem member, the handlebars having outer handgrip portions, a support arm extending slopingly upward from the vertical standard, a first bicycle-type crank assembly, supported by the standard, the first crank assembly having foot pedals, a second bicycle-type crank assembly mounted on the support arm adjacent to its outer end, above the level of the first crank assembly, the second crank assembly having handgrips, means, operable between the lower and upper crank assemblies, to cause rotation of one crank assembly on rotation of the other.
