Abstract
In one embodiment, an iceboard includes a plank having a first end and a second end and a first side and a second side. One or more supports are coupled to the first side of the plank and, one or more blades are coupled to the one or more supports, the blades operable to glide across an icy surface. The iceboard further includes a piece of frictional material coupled to the second side of the plank and operable to provide traction relative to the plank. The iceboard further includes a brake coupled to the first side of the plank adjacent a first end of the plank. In particular embodiments, the brake is operable to abrasively scrape the icy surface when applied to the icy surface.
Claims18
An apparatus, comprising:
- a plank having a first side and a second side and a first end and a second end;
- one or more supports coupled to the first side of the plank;
- one or more blades coupled to the one or more supports, the blades operable to glide across an icy surface;
- a piece of frictional material coupled to the second side of the plank, the frictional material operable to provide traction relative to the plank;
- a brake coupled to the first side of the plank, the brake operable to abrasively scrape the icy surface when applied to the icy surface, wherein the brake comprises a metal sheet, the metal sheet comprising a plurality of pointed protrusions;
- and a v-shaped plate coupled to the first side of the plank, the v-shaped plate comprising a first flat plate and a second flat plate coupled together along a common edge, the first flat plate and the second flat plate forming an acute angle therebetween, wherein:
- The v-shaped plate is coupled to the second end of the plank such that the common edge is fixed in-line with each of the one or more supports and the acute angle faces the one or more supports;
- and
- A height of the common edge extends over a majority of a height of the one or more supports such that the v-shaped plate forms a plow for the one or more supports at the second end of the plank.
