Skate spinner
View Patent ↗A skate spinner comprises a platform configured for a user's foot to be placed thereon, and a support unit forming a lower part of the platform contacting a ground surface and having a curved protruded surface starting from a front end to a rear end thereof. The support unit includes plates each having a thickness equal to at least a thickness of an ice-skate blade and being aligned in a lateral direction of the skate spinner at a predetermined distance. An overall bottom surface of the plates contacting the ground surface has a spherical surface outline.
1. A skate spinner, comprising:
a platform configured to support a user's foot, the platform having a rectangular shape with a predetermined length and a predetermined width shorter than the predetermined length; and
a supporter provided below the platform and extending along a longitudinal direction of the platform, the supporter having a bottom contacting a ground surface,
wherein the supporter includes a plurality of plates protruding from a bottom of the platform toward the ground surface and extending along the longitudinal direction of the platform with predetermined grooves formed therebetween in a lateral direction of the platform,
wherein the bottom of the supporter has a first curvature along the longitudinal direction of the platform and the first curvature is continuously formed from a front end to a rear end of the supporter,
wherein the bottom of the supporter has a second curvature along the lateral direction of the platform and the second curvature is constant from a right end to a left end of the supporter, and
wherein the bottom of the supporter has a spherical contour entirely.
2. The skate spinner of claim 1 , wherein each plate has a thickness ranging from 2 mm to 6 mm, and
wherein each groove formed between each plate is formed to have a width equal to or less than a width of an ice-skate blade.
3. The skate spinner of claim 1 , wherein the second curvature has a radius of curvature ranging from 7.5 to 8.5 feet.
4. The skate spinner of claim 1 , wherein a width of a front portion of the platform and a width of a rear portion of the platform have the same size or the front portion and the rear portion are symmetrical.
5. The skate spinner of claim 1 , wherein each plate is configured to have an edge formed thereon.
6. The skate spinner of claim 1 , wherein the supporter is detachably coupled with the platform.
7. The skate spinner of claim 1 , wherein the platform is configured to support only one of the user's feet.
8. The skate spinner of claim 1 , wherein a width of a front portion of the platform is greater than a width of a rear portion of the platform.
9. The skate spinner of claim 1 , wherein a bottom of each plate has the first curvature formed continuously from a front end to a rear end of each plate.
10. The skate spinner of claim 1 , wherein, when observing a cross-section of the supporter taken along the lateral direction of the platform, a height of each plate becomes higher starting from plates positioned at both of the right and left ends of the supporter towards a plate positioned at a center of the supporter.
