Definitions

  • ABSTRACT F THE DISCLOSURE A bottom surface for an elongated element for gliding over a surface, eg., skis, said surface having a three-dimensional pattern including a series of protuberances which are arranged in a generally continuous pattern along the bottom of the elongated element and each of which presents an exposed face inclined relative to the general plane of the bottom, each inclined exposed face terminating in a rearward direction in a convexly curved dropoff edge, said exposed faces being arranged generally in at least two parts, a forward part and a rearward part, the rearward part being at an angle of lesser inclination relative to the general plane of the bottom than is the forward part of the face, and in fact said rearward face part of lesser inclination being in some cases generally parallel to the general plane of the bottom of the elongated element.
  • This invention relates to skis, surf boards, etc., and similar devices for sliding or gliding over water, snow, ice, etc., and guided by a human practitioner, and relates to a scale surface therefor as explained in my copending patent application Ser. No. 558,738, filed June 20, 1966 ⁇ and now abandoned. Attention is also directed to United States Patent 3,269,892, dated Aug. 30, 1966.
  • Skis generally are provided with one or more longitudinal grooves formed in the base thereof for the purpose of straight and traverse tracking and stability on turns.
  • the new scaled bottom surface does not require the use of such grooves as it tracks better and has far more stability in turns than the prior art grooved ski surface.
  • the scaled bottom ski is easier to turn and control and the scales themselves provide a series of groove-like configurations of small size compared to the grooves in the conventional ski.
  • the scales are tapered off to a point of elimination in a fore-and-aft or longitudinal direction adjacent the edges of the skis, i.e., just inwardly of the steel edges: and by tapering or blending the same inwardly from no scale to a complete scale pattern covering most of the bottom of the ski, even more friction is eliminated or drastically reduced and maneuverability is increased.
  • FIG. 1 is a bottom plan view of a section of the ski embodying the present invention
  • FIG. 2 is a longitudinal sectional view on line 2-2 of FIG. l;
  • FIG. 3 is a transverse section on line 3-3 of FIG. 1;
  • FIG. 4 shows the scale outline of my previous application above identified
  • FIG. 5 is a transverse diagramamtic showing to explain the construction.
  • FIG. 6 is a section showing a modification.
  • the dropoff edges 12 in FIG. 2 are not as high as the dropof edges in FIG. 4 nor yare they as sharp.
  • the tapering edges 14 may be impressed deeper than the corresponding tapering edges in FIG. 4 so as to make the dropoff edges at 12 of approximately equal height with those shown in FIG. 4 and this invention contemplates either construction.
  • This novel form of ⁇ of scale has less friction on snow and ice (and water) than the previous scale formation, i.e., in FIG. 4, when proceeding in a forward direction, but the control on making turns is as great as before and the resistance to sliding in a rearward direction is also approximately as great.
  • the present invention also contemplates the use of blanked out areas in the regions at 18 adjacent the edges of the skis so that the scale formation here actually tapers off in a lateral direction toward the outside of the ski edges from a full scale pattern in the central portion.
  • the actual construction is one in which this formation is gradually tapered off as is attempted to be shown in dotted lines in FIG. 5.
  • the scale pattern gradually phases out at the extreme edge of the pattern whether this be at the edge ⁇ of the ski or adjacent the steel edges as shown herein.
  • the bottom of the ski is essentially flat as is indicated by the line indicated at 20 in FIG. 5.
  • the dotted lines 22 above line 20 have been eliminated either by scraping or grinding off or by simply making the mold to that shape in the first place. This provides the flats 10 as well as the fading and blank areas 18.
  • the scale formation has a very peculiar property which is that if the pattern is carried to the extreme edges of the article, there is a crowding in towards the center of the material of the surface over which the ski is passing. That is, for instance in light powdery snow, the snow tends to crowd in towards the center of the ski due to the scale effect and fail to liow outwardly.
  • the present invention retains all the advantages of the scale surface as in my copending patent application identified above, but at the same time speed in a forward direction is enhanced and lateral control as for instance on turns, etc., is retained.
  • FIGS. 5 and 6 are exaggerated in order to more clearly show the construction and the action involved in these forms of the invention.
  • a device for gliding over a surface comprising an elongated element having a main body portion, a ont end and arear end, and a three dimensional patterned bottom, the pattern including a plurality of protuberances which extend outwardly from the main body portion of the element, certain of said protuberances presenting a convexly curved edge located at an angle to the general plane of the bottom of the element, each edge including a portion facing rearwardly, certain of said protuberances having surface-contacting areas which incline relative to the plane of the bottom from a minimum thickness in the forward direction of motion of the element to a maximum in a rearward direction and terminating in said edges, said protuberances being aligned in rows transverse of the element, certain rows being aligned in a fore-and-aft direction relative to the element, and certain rows being misaligned in the fore-and-aft direction.
  • the pattern including a plurality of protuberances certain of which each present a convexly curving edge located at an angle to the general plane of the bottom of the element, each edge presenting its curve generally toward the rear,
  • protuberances each having an exposed face which includes a forward part and a rearward part, the forward part of each exposed face being located on an incline extending outwardly from the general plane of the bottom toward the rear, from a minimum forwardly thereof to a maximum rearwardly,
