Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
177 words
An endless and substantially flat track for use with a multiterrain vehicle, said track having an inner and outer surface with a tread pattern on the outer surface, and said track capable of being propelled by a drive wheel, which comprises: an elastomeric body; a substantially endless textile tensile member oriented longitudinally with respect to the track, said textile tensile member disposed within said elastomeric body in generally uniformly laterally spaced relation substantially across the width of said elastomeric body; a plurality of closely-spaced multifilament textile stiffening members arranged and spaced-apart by perpendicular cords separate from said tensile member providing a leno weave fabric oriented substantially perpendicularly with respect to said textile tensile member and disposed within said elastomeric body, said textile stiffening members having a bend modulus of at least 1.2 inch-pounds per longitudinal inch of said elastomeric body whereby the stiffness of the track transversely is greater than the stiffness of the track longitudinally; and a positive drive means for receiving a drive wheel from the inner surface of the track to propel the track.
Claim 2
Dependent Claim
177 words
An endless and substantially flat track for use with a multiterrain vehicle, said track having an inner and outer surface with a tread pattern on the outer surface, and said track capable of being propelled by a drive wheel, which comprises: an elastomeric body; a substantially endless textile tensile member oriented longitudinally with respect to the track, said textile tensile member disposed within said elastomeric body in generally uniformly laterally spaced relation substantially across the width of said elastomeric body; a plurality of closely-spaced multifilament textile stiffening members arranged and spaced-apart by perpendicular cords separate from said tensile member providing a leno weave fabric oriented substantially perpendicularly with respect to said textile tensile member and disposed within said elastomeric body, said textile stiffening members having a bend modulus of at least 1.2 inch-pounds per longitudinal inch of said elastomeric body whereby the stiffness of the track transversely is greater than the stiffness of the track longitudinally; and a positive drive means for receiving a drive wheel from the inner surface of the track to propel the track.

Claim 5
Dependent Claim
45 words
An endless and substantially flat track according to claim 1 which further includes: at least one metal cable longitudinally arranged with respect to the track and disposed within the elastomeric body near each outside edge of the track to deter lateral tearing of the track.
Claim 6
Dependent Claim
43 words
An endless and substantially flat track as claimed in claim 1 wherein said means for receiving the drive wheel comprises at least one longitudinal row of evenly spaced lugs protruding from the inner surface of the track for engagement with the drive wheel.
Claim 7
Dependent Claim
41 words
An endless and substantially flat track as claimed in claim 1 wherein said means for receiving the drive wheel comprises said elastomeric body having at least one longitudinal row of evenly spaced sprocket teeth-receiving openings for engagement with the drive wheel.
Claim 8
Dependent Claim
51 words
An endless and substantially flat track as claimed in claim 6 and further including a suBstantially flat reinforcement member disposed around and away from said sprocket teeth-receiving openings a distance at least equivalent to the largest dimension of said sprocket teeth-receiving openings and said reinforcement member disposed within said elastomeric body.
Claim 9
Dependent Claim
88 words
An endless and substantially flat track as claimed in claim 1 wherein the means for receiving the drive wheel comprises said elastomeric body having at least one longitudinal row of evenly spaced sprocket teeth-receiving openings for meshing with the drive wheel, and at least one longitudinal row of evenly spaced lugs having drive surfaces for meshing with the drive wheel and having edges for transmitting lateral forces to the drive while, said lugs protruding outwardly and away from the inner surface of the substantially flat and endless track.
Claim 10
Dependent Claim
53 words
An endless and substantially flat track as claimed in claim 8 and further including a substantially flat reinforcement member disposed around and radially away from said sprocket teeth-receiving openings a distance at least equivalent to one-half the largest dimension of said sprocket teeth-receiving openings and said reinforcement member disposed within said elastomeric body.
Claim 11
Dependent Claim
115 words
An endless and substantially flat track according to claim 1 which further includes: a plurality of substantially parallel tread elements having essentially flat sides that protrude outwardly and away from the outer surface of the endless and substantially flat track, the sides of said tread elements forming an angle of at least 90* with respect to the outer surface of the endless and substantially flat track, and the contiguous sides of any pair of said tread elements having a summation of angles as formed with respect to the outer surface of said endless and substantially flat track of between 200* and 300* whereby a trapezoidal-shaped void is formed between any two of said tread elements.
Claim 12
Dependent Claim
51 words
