Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
150 words
A roller skate construction comprising plate means having a first longitudinal axis relative to which said plate means is pivoted to vary the amount of lean thereof, an axle having a second longitudinal axis extending transversely to said first longitudinal axis and having opposite ends for mounting wheels, and mounting means for mounting said axle for pivotal movement relative to said plate means solely about a fixed point centrally located on said second longitudinal axis in response to varying the amount of lean to which said plate means is subjected, said mounting means including means for preventing movement of said fixed point relative to said plate means, whereby lateral forces applied to said wheels at the point of engagement of said wheels with the ground will not influence plate lean and whereby a given amount of plate lean will always produce a predetermined angle between said first and second axes.
Claim 2
Dependent Claim
150 words
A roller skate construction comprising plate means having a first longitudinal axis relative to which said plate means is pivoted to vary the amount of lean thereof, an axle having a second longitudinal axis extending transversely to said first longitudinal axis and having opposite ends for mounting wheels, and mounting means for mounting said axle for pivotal movement relative to said plate means solely about a fixed point centrally located on said second longitudinal axis in response to varying the amount of lean to which said plate means is subjected, said mounting means including means for preventing movement of said fixed point relative to said plate means, whereby lateral forces applied to said wheels at the point of engagement of said wheels with the ground will not influence plate lean and whereby a given amount of plate lean will always produce a predetermined angle between said first and second axes.
Claim 3
Dependent Claim
74 words
A roller skate construction as set forth in claim 1 wherein said mounting means include a body member extending downwardly from said plate means, pin means on said body member extending at an angle to the vertical for securing said axle thereto, said pin means including a third longitudinal axis which intersects said second longitudinal axis at said fixed point, and bearing means mounting said axle for pivotal movement relative to said body member.
Claim 4
Dependent Claim
35 words
A roller skate construction as set forth in claim 2 wherein said means included in said mounting means comprises means for mounting said pin means and said axle against longitudinal movement along said third axis.
Claim 5
Dependent Claim
117 words
A roller skate construction as set forth in claim 3 including a second body member secured to said plate in spaced relationship along said first longitudinal axis from said first body member, a second axle having a fourth longitudinal axis and having opposite ends for mounting wheels, second pin means on said second body member for securing said second axle to said second body member, said second pin means extending at an equal and opposite angle to the vertical as said pin means, said second pin means including a fifth longitudinal axis which intersects said fourth longitudinal axis at a second fixed point, said fixed point and said second fixed point lying along said first longitudinal axis.
Claim 6
Dependent Claim
43 words
A roller skate construction as set forth in claim 2 wherein said axle has a central portion with an aperture located therein and wherein said pin means extends through said aperture and wherein said bearing means mounts said axle on said pin means.
Claim 7
Dependent Claim
27 words
A roller skate construction as set forth in claim 2 including adjusting means for adjusting the angle which said pin means makes with the said plate means.
Claim 8
Dependent Claim
70 words
A roller skate construction as set forth in claim 6 wherein said adjusting means comprises plug means having a plug axis extending transversely to said longitudinal axis, means mounting said pin means on said plug means, said plug means being rotatable about said plug axis to thereby vary the angle of said pin means, and means for securing said plug means in the position to which it has been rotated.
Claim 9
Dependent Claim
45 words
A roller skate construction as set forth in claim 2 including resilient bushing means mounted on said axle on opposite sides of said central portion and Having first portions in abutting engagement with said body member and second portions in effective engagement with said wheels.
Claim 10
Dependent Claim
24 words
A roller skate construction as set forth in claim 8 wherein said bearing means are ball bearings mounting said axle on said pin means.
Claim 11
Dependent Claim
74 words
A roller skate construction as set forth in claim 8 wherein the distance between said first and second portions of each bushing is a predetermined amount, and wherein means are located on said axle a predetermined distance from said fixed point for limiting the distance said wheels may move onto said axle, whereby said resilient bushing means are always placed in the same amount of compression when said wheels are tightened on said axle.
Claim 12
Dependent Claim
24 words
A roller skate construction as set forth in claim 10 wherein said bearing means are ball bearings mounting said axle on said pin means.
Claim 13
Dependent Claim
82 words
A roller skate construction as set forth in claim 10 wherein said resilient bushing means are frustoconical in shape and have an axis of rotation, and aperture means in said bushing means coincident with said axis of rotation to permit said bushing means to fit on said axle with said axis of rotation coincident with said second longitudinal axis, said bushing means having a larger base and a smaller base with said larger base in effective abutting engagement with said body member.
