Publication number: 20160144935Abstract: Accessories for sports apparatuses are shown and described. The sports apparatuses may be surfboards. The accessories take the form of thin layers of material for application to an area where selective patterning of wax is desired. The accessories include patterned textures which selectively encourage wax accumulation in desirable patterns. Illustrative accessories may have single or multiple layers, and allow for ready removal of old, used and/or dirty wax with less effort than conventional approaches.Type: ApplicationFiled: November 20, 2015Publication date: May 26, 2016Applicant: Wax Traks, IncorporatedInventors: Robert Collins Harrell, Jaron Collins Harrell

Patent number: 4714266Abstract: A running-surface plastic coating for skis which comprises a running surface forming a climbing aid and having a multiplicity of teeth which are aligned in the longitudinal direction of the ski and terminate towards the rear end of the ski in a pointed end capable of being bent upwards, said teeth being defined by two families of parallel running-surface cuts intersecting each other in the running surface, the individual families of cuts being inclined to a normal of the running surface in opposite directions wherein the running surface cuts at least substantially have the shape of circular segments and include an angle of at least 60.degree. with a running-surface normal, and that the relative spacing of the running-surface cuts is at most 1 mm.Type: GrantFiled: October 7, 1985Date of Patent: December 22, 1987Assignee: Trak IncorporatedInventor: Werner Feichtlbauer

Patent number: 4565387Abstract: A running-surface plastics coating for skis comprises a running surface forming a climbing aid and provided with a multiplicity of tongues (4) which are aligned in the longitudinal direction of the ski and terminate towards the rear end of the ski in pointed ends capable of being bent upwards to provide a means for reducing the sliding resistance in the running direction without impairing the climbing aid. The tongues (4) are defined by cuts (2a, 2b) provided in the running-surface coating (1), at an acute angle with each other, the cuts extending from the plane running surface toward the underside of the ski and including an acute angle with that plane so that the inwardly and upwardly slanted side edge surfaces of each tongue are rhomboidal and diverge with respect to each other from the tip of that tongue.Type: GrantFiled: October 29, 1984Date of Patent: January 21, 1986Assignee: Trak IncorporatedInventor: Werner Feichtlbauer

Patent number: 4313614Abstract: An improved ski, having an upper surfacing material and a lower surfacing material, the two surfacing materials being separated by, and affixed to, a core material throughout substantially the entire length of the ski, the improvement comprising a continuous belt of fiber-glass reinforced laminate bonded to a polyethylene surface layer, which belt forms both the upper and lower surfacing material and which is bent around the core material so that the polyethylene layer forms the bottom running surface as well as the upper surface, the belt further forming an integral guard around the core material of the rear end of the ski.Type: GrantFiled: June 18, 1979Date of Patent: February 2, 1982Assignee: Trak IncorporatedInventors: Hans Woitschatzke, Hennoch Geyer

Patent number: 4223909Abstract: A ski with an improved, three-dimensional, running surface with a plurality of protuberances inclined with respect to the bottom plane of the running surface by rising towards the rear end of the ski, and the surface further characterized by a longitudinal pattern comprising: a gliding region beginning near the front end of the ski, wherein the protuberances terminate in convexly shaped, drop-off edges; a transition region, wherein the protuberances terminate in straight, drop-off edges, followed by a kick region roughly in the center of the ski's camber, wherein the protuberances terminate in concavely shaped, drop-off edges, followed by a second transition region; and a rear-glide region extending to near the rear end of the ski.Type: GrantFiled: March 1, 1979Date of Patent: September 23, 1980Assignee: Trak IncorporatedInventors: William D. Danner, Hans Woitschatzke
-
Patent number: 4178012Abstract: A three-dimensional ski base and skis having the ski base secured thereto as a running surface, the ski base comprising a plurality of scale-like protuberances inclined with respect to the bottom plane of the running surface of the ski and which rise toward the rear end of the ski, the surfaces of the protuberances convexly curved both in a longitudinal and in a transverse direction of the running surface to provide a resistance to backward movement and improved sliding properties in forward movement.Type: GrantFiled: December 2, 1977Date of Patent: December 11, 1979Assignee: Trak IncorporatedInventors: Walter Roth, Hans Woitschatzke
