Claims
- 1. A base of a runner for gliding over snow, the base comprising:
a front portion including a flat running surface generally defining a first surface plane; a rear portion including a central running surface and a first inner edge located along at least a portion of the perimeter of said central running surface; and a first outer portion disposed adjacent said central running surface, said first outer portion including a first outer running surface and a first outer edge located along at least a portion of the perimeter of said first outer running surface, wherein at least a portion of said first inner edge is at a different elevation than said first surface plane.
- 2. The base of claim 1, further comprising a second inner edge and a second outer portion, said second inner edge being located along at least a portion of the perimeter of said central running surface on the opposite side of said central running surface from said first inner edge, said second outer portion being disposed adjacent said second inner edge, said second outer portion including a second outer running surface and a second outer edge located along at least a portion of the perimeter of said second outer running surface, wherein at least a portion of said second inner edge is at a different elevation than said first surface plane.
- 3. The base of claim 2, wherein said central running surface is curved longitudinally and is substantially straight across in a lateral direction along substantially the entire length of said central running surface.
- 4. The base of claim 2, wherein said central running surface is substantially planar along substantially the entire length thereof.
- 5. The base of claim 2, wherein said first inner edge lies generally parallel to said second inner edge along at least a portion of the length of the base.
- 6. The base of claim 2, wherein said first and second outer running surfaces and said first and second inner edges, respectively, are symmetric about the longitudinal axis of the base.
- 7. The base of claim 1, wherein said front surface plane is substantially coplanar with said central running surface.
- 8. The base of claim 1, wherein the elevation of said central running surface decreases with respect to said first surface plane as said central running surface extends in the rearwardly direction.
- 9. The base of claim 1, wherein said first and second inner edges taper toward the longitudinal axis of said base as said inner edges extend in the rearward direction.
- 10. The base of claim 1, wherein said central running surface begins at a location rear of the approximate longitudinally midpoint of the base.
- 11. The base of claim 1, wherein an angle formed between said central running surface and a line running between said first outer edge and said first inner edge at the approximate rearward wide point lies in the range of between 0.1 and 10 degrees.
- 12. A snow traversing apparatus comprising:
an elongate body having a front end, rear end, a top surface and a base that extends along the approximate length of the body, said base including:
(i) a front portion extending between approximately the longitudinal midpoint of said elongate body and the front end, said front portion defining a front running surface that is planar across the entire front portion in the lateral direction as the front running surface extends to said end of said body; (ii) a rear portion extending between the end of said front portion disposed at approximately the longitudinal midpoint of said elongate body and said rear end of said elongate body, said rear portion including:
(a) a central running surface generally defining a central surface plane; two outer running surfaces, a portion of said central running (b) surface being at a different elevation than said outer running surfaces; and (c) first and second inner edges disposed between said central running surface and said first and second outer running surfaces, respectively; and (iii) first and second outer edges surrounding a portion of the perimeter of said first and second outer running surfaces, respectively.
- 13. The apparatus of claim 12, wherein said central running surface is curved longitudinally and is substantially straight across in a lateral direction along substantially the entire length of said central running surface.
- 14. The apparatus of claim 12, wherein a portion of said central running surface is at a lower elevation than said outer running surfaces.
- 15. The apparatus of claim 12, wherein said front running surface is substantially coplanar with said central running surface.
- 16. The apparatus of claim 12, wherein said central running surface begins at a location rear of the approximate midpoint of said elongate body.
- 17. A base of a runner for gliding over snow, the base comprising:
a front portion including a flat running surface generally defining a first surface plane; a rear portion having a removably attachable stepped portion, said stepped portion including a central running surface and first and second inner edges located along at least a portion of the perimeter of said central running surface; and a first outer portion disposed adjacent to said stepped portion, said first outer surface including a first outer running surface and a first outer edge located along at least a portion of the perimeter of said first outer running surface, wherein at least a portion of said first inner edge is at a different elevation than said first surface plane; and a second outer portion disposed adjacent to said stepped portion on the side opposite of said first outer portion, said second outer portion including a second outer running surface and a second outer edge located along at least a portion of the perimeter of said second outer running surface, wherein at least a portion of said second inner edge is at a different elevation than said first surface plane.
- 18. The base of claim 17, wherein a portion of said central running surface is at a lower elevation than said outer running surfaces.
- 19. The base of claim 17, wherein said front surface plane is substantially coplanar with said central running surface.
- 20. The base of claim 17, wherein said central running surface begins at a location rear of the approximate longitudinal midpoint of said base.
