摘要： Disclosed herein is a length adjustable skate blade guard. The blade guard includes a first guard surrounding at least portion of a lower surface of a skate blade and a front end of the skate blade. A second guard surrounds a remaining portion of the lower surface of the skate blade and a rear end of the skate blade. At least one extension block is coupled between the first guard and the second guard, and extends a length of the guard to correspond to a length of the skate blade. At least one elastic body is secured at opposite ends thereof to the first guard and the second guard, respectively, the elastic body elastically putting the facing first and second guards in close contact with each other.

摘要： 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.
