Abstract
Abstract Exercising apparatus that is especially adapted to impart a particular desirable motion into the lower limbs of an individual who may be suffering from paralysis and certain other muscular injuries or disorders. The apparatus includes a fixed base to which there is captured a sliding base, with the sliding base having an oscillating foot rest located thereon. A seat is resiliently mounted to the fixed base and a control lever is disposed in proximity of a person seated thereon for controlling the location of the foot rest relative to the seat. Reciprocatory motion is used to induce oscillatory motion into the foot rest, while the seat moves in response thereto so as to impart a particular exercising motion into the lower limbs of the patient''s anatomy. The severity of the motion induced into the patient''s leg is controlled by the patient himself who avoids straining his impaired muscles by positioning the lever to thereby control the amount of force imparted into his body.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
Exercising apparatus for inducing motion into the lower extremity of a person''s body, comprising: a fixed base, a seat, a sliding base, and a foot rest; means by which said sliding base is slidably supported by said fixed base; means resiliently mounting said seat to said fixed base in spaced apart relationship with respect to said sliding base; pivot means for pivotally mounting said foot rest to said sliding base, and said foot rest being spaced apart with respect to said seat; power means for inducing oscillatory motion into said foot rest so as to pivot said foot rest a limited distance about said pivot means, and; means for moving said sliding base relative to said seat and said fixed base, whereby: a person can be seated on said seat with one foot rested upon said foot rest, so as to cause motion to be induced into a lower extremity of his body.
Claim 2
Dependent Claim
153 words
Exercising apparatus for inducing motion into the lower extremity of a person''s body, comprising: a fixed base, a seat, a sliding base, and a foot rest; means by which said sliding base is slidably supported by said fixed base; means resiliently mounting said seat to said fixed base in spaced apart relationship with respect to said sliding base; pivot means for pivotally mounting said foot rest to said sliding base, and said foot rest being spaced apart with respect to said seat; power means for inducing oscillatory motion into said foot rest so as to pivot said foot rest a limited distance about said pivot means, and; means for moving said sliding base relative to said seat and said fixed base, whereby: a person can be seated on said seat with one foot rested upon said foot rest, so as to cause motion to be induced into a lower extremity of his body.
Claim 3
Dependent Claim
56 words
The apparatus of claim 1, wherein said means for inducing oscillatory motion into said foot rest includes a connecting rod, means for inducing reciprocatory motion into said rod which includes a shaft, an eccentric affixed to said shaft, said connecting rod having one end thereof affixed to said eccentric, and a motor for rotating said shaft.
Claim 4
Dependent Claim
23 words
The apparatus of claim 1, wherein said foot rest includes means by which it can be moved towards and away from said seat.
Claim 5
Dependent Claim
80 words
The apparatus of claim 1, wherein said means for moving said sliding base includes lever means affixed to said fixed base and having an end thereof disposed in close proximity of said chair so that a person seated therein can control the action of the lever, linkage means, said lever being connected to said sliding base by said linkage means so that a person seated in said seat can control the degree of bend to which his knee is subjected.
Claim 6
Dependent Claim
48 words
The apparatus of claim 1, wherein said seat is mounted in spaced apart relationship with respect to said fixed base by a resilient member, said resilient member enabling said seat to move relative to said fixed base in response to the oscillatory motion imparted into said foot rest.
Claim 7
Dependent Claim
73 words
The apparatus of claim 1, wherein said means for inducing oscillatory motion into said foot rest includes a connecting rod, means for inducing reciprocatory motion into said rod which includes a shaft, an eccentric affixed to said shaft, said connecting rod having one end thereof affixed to said eccentric, and a motor for rotating said shaft; said foot rest includes means by which it can be moved towards and away from said seat.
Claim 8
Dependent Claim
65 words
The apparatus of claim 1, wherein said foot rest includes means by which it can be moved towards and away from said seat; said seat is mounted in spaced apart relationship with respect to said fixed base by a resilient member, said resilient member enabling said seat to move relative to said fixed base in response to the reciprocatory motion imparted into said foot rest.
