Abstract
Abstract A skate device includes a molded plastic form, a triangular plate and a pneumatic wheel. The plastic form is adapted to fit about the foot and has slightly downward extending forward and rear integral portions. The triangular plate is mounted under the molded form and extends along the center of the foot arch, forming the base frame of the skate to which the pneumatic wheel is attached. The wheel is secured to a bent end portion of this triangular plate at the outside of the foot. A second smaller wheel may optionally be attached to a bent end base portion of the triangular plate at the inside of the foot. The skate may be secured to the foot by laces.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
168 words
A skate device adapted for attachment to a foot and designed to provide ease and safety of movement for walking, running, coasting and standing comprising: (a) a molded plastic form adapted to fit about the foot; (b) a triangular plate mounted under the plastic form, said plate extending beneath the sole of the foot along the center of the arch and positioned so that its base is at the inside of the foot near the arch and its point is at the outside of the foot; said plate configured so as to comprise a main horizontal part extending beneath the sole of the foot, a vertical part extending upward at the outside of the foot approximately perpendicular to said main part, and a portion containing the point extending outward from said vertical part; and (c) a pneumatic wheel adapted to rotate about a fixed center, the point of said triangular plate passing through an aperture in the fixed center so as to secure the wheel to the plate.
Claim 2
Dependent Claim
168 words
A skate device adapted for attachment to a foot and designed to provide ease and safety of movement for walking, running, coasting and standing comprising: (a) a molded plastic form adapted to fit about the foot; (b) a triangular plate mounted under the plastic form, said plate extending beneath the sole of the foot along the center of the arch and positioned so that its base is at the inside of the foot near the arch and its point is at the outside of the foot; said plate configured so as to comprise a main horizontal part extending beneath the sole of the foot, a vertical part extending upward at the outside of the foot approximately perpendicular to said main part, and a portion containing the point extending outward from said vertical part; and (c) a pneumatic wheel adapted to rotate about a fixed center, the point of said triangular plate passing through an aperture in the fixed center so as to secure the wheel to the plate.
Claim 3
Dependent Claim
26 words
The skate device defined in claim 1, further comprising a second wheel attached to the base of the triangular plate facing the inside of said foot.
Claim 4
Dependent Claim
37 words
The skate device defined by claim 2, wherein the triangular plate further includes a portion extending downward from said main part at the base of said plate, the second wheel being attached to said downward extending portion.
Claim 5
Dependent Claim
57 words
The skate device of claim 1 wherein the wheel rotates about a fixed center, the wheel being attached to the triangular plate by inserting the point of the plate through a slotted aperture in the fixed center and then bending the end of the outward extending portion of the plate downward so that the point faces down.
Claim 6
Dependent Claim
30 words
The skate device of claim 4 wherein the skate device is secured to the foot by means of a tether passing through holes in the fixed center of the wheel.
Claim 7
Dependent Claim
19 words
The skate device of claim 1 wherein the molded plastic form includes downward extending forward and rear integral portions.
Claim 8
Dependent Claim
39 words
The skate device of claim 4 wherein the fixed center of the wheel is shaped so that its surface is concave on the side facing outward from the foot and convex on the side facing inward to the foot.
Claim 9
Dependent Claim
142 words
A skate device adapted for attachment to a foot and designed to provide ease and safety of movement for walking, running, coasting and standing comprising: (a) a molded plastic form adapted to fit about the foot; (b) a triangular plate mounted under the plastic form, said plate extending beneath the sole of the foot along the center of the arch and positioned so that its base is at the inside of the foot near the arch and its point is at the outside of the foot; and (c) a pneumatic wheel adapted to rotate about a fixed center and attached to the triangular plate at the outside of the foot, the point of the plate passing through a slotted aperture in the fixed center of the wheel and then downward at the outside of the wheel so that the point faces down.
Claim 10
Dependent Claim
142 words
A skate device adapted for attachment to a foot and designed to provide ease and safety of movement for walking, running, coasting and standing comprising: (a) a molded plastic form adapted to fit about the foot; (b) a triangular plate mounted under the plastic form, said plate extending beneath the sole of the foot along the center of the arch and positioned so that its base is at the inside of the foot near the arch and its point is at the outside of the foot; and (c) a pneumatic wheel adapted to rotate about a fixed center and attached to the triangular plate at the outside of the foot, the point of the plate passing through a slotted aperture in the fixed center of the wheel and then downward at the outside of the wheel so that the point faces down.
Claim 11
Dependent Claim
30 words
The skate device of claim 8 wherein the skate device is secured to the foot by means of a tether passing through holes in the fixed center of the wheel.
Claim 12
Dependent Claim
39 words
The skate device of claim 8 wherein the fixed center of the wheel is shaped so that its surface is concave on the side facing outward from the foot and convex on the side facing inward to the foot.
