| Abstract: |
A snow scraper attached to a ski pole shaft includes an elongated member having an exterior surface and a wall. The ski pole shaft extends through a longitudinally oriented, cylindrical channel in the member. The member has a substantially planar exterior surface portion oriented tangentially to the channel and spaced outwardly from the channel. A radial slot extends from the channel perpendicularly toward and intersects the substantially planar exterior surface portion. Two longitudinally extending edges are defined by second and third exterior surface portions that intersect with the substantially planar exterior surface portion. Inwardly concave, exterior surface portions are located between the edge and the channel in the sidewall of the member. A means for clamping the member to a ski pole shaft is also included.

First Claim:
Show all 6 claims |
What is claimed is:
1. A snow scraper for attachment to a ski pole shaft comprising:
- a unitary elongated member having a wall, said wall defining an elongated channel through said member oriented longitudinally along said member, said channel being substantially cylindrical so as to circumscribe said ski pole shaft, said member having at least one longitudinally oriented, straight scraping edge formed by first and second intersecting exterior surface portions of said wall, said first surface portion being substantially planar and being oriented substantially parallel to a tangent to said channel and being spaced outwardly from said channel, said wall having a longitudinal slot therein extending from said channel to the plane of said first surface portion, said edge being laterally offset from said slot, said wall having a concave exterior surface portion adjacent said edge, said concave surface portion being located in said wall between said first surface portion and said channel and intersecting said second surface portion, and
- attachment means for securing said member to a ski pole shaft by decreasing the width of said slot and thereby reducing the diametric dimension of said channel to place the surface of said channel in intimate contact with said ski pole shaft, said attachment means being located between the plane of said first surface portion and said channel.
