Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
86 words
An exercise machine, comprising: pedal means mounted for rotation about a longitudinal axis, crib means for supporting a user and mounted for oscillating motion along a linear path, means coupled to said pedal means for causing oscillating movement of said pedal assembly along a prescribed arc in response to rotation of said pedal assembly about said longitudinal axis, and means for causing oscillating movement of said crib means along said linear path in synchronism with said oscillating movement of said pedal assembly along said prescribed arc.
Claim 2
Dependent Claim
86 words
An exercise machine, comprising: pedal means mounted for rotation about a longitudinal axis, crib means for supporting a user and mounted for oscillating motion along a linear path, means coupled to said pedal means for causing oscillating movement of said pedal assembly along a prescribed arc in response to rotation of said pedal assembly about said longitudinal axis, and means for causing oscillating movement of said crib means along said linear path in synchronism with said oscillating movement of said pedal assembly along said prescribed arc.
Claim 3
Dependent Claim
81 words
Exercise machine according to claim 1 wherein said pedal means includes a set of pedal crank arms rotatably mounted on a shaft and wherein said means coupled to said pedal means includes a first link pivotably mounted on said shaft and a second link pivotably coupled to said first link, and means for displacing said second link so as to produce said oscillating movement of said pedal means along said prescribed arc in response to rotation of said pedal crank arms.
Claim 4
Dependent Claim
49 words
Exercise machine according to claim 1 wherein said means for causing oscillating movement of said crib means includes a link pivotably coupled to said crib and means for displacing said link so as to produce said oscillating movement of said crib in response to rotation of said pedal means.
Claim 5
Dependent Claim
26 words
Exercise machine according to claim 1 wherein said oscillating movement of said pedal means and said oscillating movement of said crib means are in opposed directions.
Claim 6
Dependent Claim
107 words
Exercise machine, comprising: pedal means mounted for rotation on a shaft, a first link pivotably coupled to said shaft, a second link pivotably coupled to said first link, means for displacing said second link so as to produce oscillating movement of said first link over a prescribed arc in response to rotation of said pedal means about said shaft, a crib mounted for oscillating movement along a linear path, a third link pivotably coupled to said crib, and means for displacing said third link so as to produce oscillating movement of said crib along said linear path in synchronism with said oscillating movement of said first link.
Claim 7
Dependent Claim
107 words
Exercise machine, comprising: pedal means mounted for rotation on a shaft, a first link pivotably coupled to said shaft, a second link pivotably coupled to said first link, means for displacing said second link so as to produce oscillating movement of said first link over a prescribed arc in response to rotation of said pedal means about said shaft, a crib mounted for oscillating movement along a linear path, a third link pivotably coupled to said crib, and means for displacing said third link so as to produce oscillating movement of said crib along said linear path in synchronism with said oscillating movement of said first link.
Claim 8
Dependent Claim
25 words
Exercise machine according to claim 5 wherein said oscillating movement of said first link and said oscillating movement of said crib occur in opposed directions.
Claim 9
Dependent Claim
27 words
Exercise machine according to claim 5 wherein said means for displacing said second link includes a chain and sprocket wheel transmission operatively associated with said pedal means.
Claim 10
Dependent Claim
27 words
Exercise machine according to claim 5 wherein said means for displacing said third link includes a chain and sprocket wheel transmission operatively associated with said pedal means.
Claim 11
Dependent Claim
30 words
Exercise machine according to claims 7 or 8 including means for adjusting the position of said shaft so as to alter the tension of said chain and sprocket wheel transmission.
Claim 12
Dependent Claim
19 words
Exercise machine according to claims 7 or 8 including means for adjustably braking said chain and sprocket wheel transmission.
Claim 13
Dependent Claim
