Abstract

Various embodiments provide an improved snow pusher with a removable friction-reducing edge. An example embodiment includes a blade having a generally rectangular shape and being of rigid material, the blade including an angled lower portion; a slider for removable attachment to the angled lower portion of the blade, the slider being fabricated from a friction-reducing material; a handle attachment mechanism for removable attachment to the blade; and a handle for removable attachment to the handle attachment mechanism.

Independent Claims | See all claims (18)

  1. 1. An apparatus comprising: a blade having a generally rectangular shape and being of rigid material, the blade including an angled lower portion; a slider, having an attachment edge and a lower surface, for removable attachment to the angled lower portion of the blade at the attachment edge of the slider, the slider being a generally long and wide piece of friction-reducing material without parts moving relative to each other, the slider being formed of a friction-reducing high-density polyethylene material, the lower surface being a flat planar surface, which is generally parallel to a surface over which the slider is moved such that the slider provides slanted leading and trailing edges when moved in either a forward or backward direction, the slanted leading edge forming a first acute angle relative to the flat planar surface of the lower surface, the slanted trailing edge forming a second acute angle relative to the flat planar surface of the lower surface, the first acute angle and the second acute angle both being fixed acute angles and both being concurrently present, the leading and trailing edges being self-sharpening as the slider is moved across the surface; a handle attachment mechanism for removable attachment to the blade; and a handle for removable attachment to the handle attachment mechanism.
  2. 11. An apparatus comprising: a blade means having a generally rectangular shape and being of rigid material, the blade including an angled lower portion; a slider means, having an attachment edge and a lower surface, for removable attachment to the angled lower portion of the blade means at the attachment edge of the slider means, the slider means being a generally long and wide piece of friction-reducing material without parts moving relative to each other, the slider means being formed of a friction-reducing high-density polyethylene material, the lower surface being a flat planar surface, which is generally parallel to a surface over which the slider means is moved such that the slider means provides slanted leading and trailing edges when moved in either a forward or backward direction, the slanted leading edge forming a first acute angle relative to the flat planar surface of the lower surface, the slanted trailing edge forming a second acute angle relative to the flat planar surface of the lower surface, the first acute angle and the second acute angle both being fixed acute angles and both being concurrently present, the leading and trailing edges being self-sharpening as the slider means is moved across the surface; a handle attachment means for removable attachment to the blade means; and a handle means for removable attachment to the handle attachment means.
