Abstract
Ice skateboards, ice skateboard conversion kits, and methods for converting a skateboard to an ice skateboard are presented. An ice skateboard or an ice skateboard conversion kit may include four blades. Each blade may include an elongate sharp lower edge and an opening for pivotally mounting the blade on one of four skateboard axle ends. Eight spacer bushings each may include a bore for pivotally mounting the spacer bushing on one of the axle ends. Lengths of two of the spacer bushings may be configured to dispose at least one of the blades along a middle third of one of the axle ends when the blade is pivotally mounted to the axle end between the two spacer bushings.
Claims19
An ice skateboard conversion kit, comprising:
- a blade comprising an elongate sharp lower edge and an opening for pivotally mounting the blade on a skateboard axle end;
- and
- two spacer bushings, each spacer bushing comprising a bore for pivotally mounting the spacer bushing on the axle end and a flat proximal face for laterally abutting the blade, wherein at least one of the two spacer bushings comprises a blade engagement member extending from the flat proximal face, the blade engagement member being shaped to extend into and support the opening of the blade, and wherein each spacer bushing comprises a recess configured to receive therein a bearing, the recess and bore of each spacer being open to each other;
- wherein lengths of the spacer bushings are configured to dispose the blade along a predetermined portion of the axle end when the blade is pivotally mounted to the axle end between the two spacer bushings.
An ice skateboard, comprising:
- a skateboard deck;
- a pair of skateboard trucks coupled to the skateboard deck, each truck comprising two axle ends;
- four blades, each blade comprising a flat metal body, the flat metal body of each blade comprising an elongate sharp lower edge and an opening by which the blade is pivotally mounted to one of the axle ends, each elongate sharp lower edge comprising a symmetrical, V-shaped cross-section;
- two spacer bushings on each axle end and abutting therebetween a respective one of the four blades, each spacer bushing comprising a bore for pivotally mounting the spacer bushing on the axle end and a proximal face for abutting the blade, wherein at least one of the two spacer bushings comprises a blade engagement member extending from the proximal face, the blade engagement member being shaped to extend into and support the opening of the blade, and wherein each spacer bushing comprises a recess configured to receive therein a bearing, the recess and bore of each spacer being open to each other;
- and
- a bearing positioned within each recess of the spacer bushings, each bearing comprising a bearing bore sized to receive an axle end.
A method of converting a skateboard to an ice skateboard, the skateboard having wheels mounted to axle ends, the method comprising:
- removing the wheels from each axle end;
- mounting, on each axle end, a first bearing, a first spacer bushing, a blade, a second spacer bushing, and a second bearing, the first bearing disposed within the first spacer bushing, the second bearing disposed within the second spacer bushing, and the blade disposed between the first spacer bushing and the second spacer bushing, wherein at least one of the first spacer bushing and second spacer bushing comprises a flat proximal surface that laterally abuts the blade and a blade engagement member that extends from the flat proximal surface of the at least one of the first spacer bushing;
- extending the blade engagement member into a hole in the blade to support the blade on the blade engagement member;
- and
- extending each axle end through the first bearing and second bearing to support the first bearing and second bearing directly on the axle end, the first bearing and second bearing supporting the first spacer bushing and second spacer bushing indirectly on the axle end such that the first spacer bushing and second spacer bushing do not contact the axle end.
