Definitions

  • the disclosed invention relates generally to snow sliding devices and covers and more particularly to snow skis, snow skates and hard-pack skis and covers therefor and methods of making and using the same.
  • skis Over the thousands of years that skis have been used to travel over snow, there has been a continuing quest for skis with improved performance, durability, and longevity of life. Early skis were made exclusively from wood that was treated in various ways to achieve those ends. In the late 1800s, ski manufacturers began laminating the skis with various materials. Most present-day skis are manufactured by laminating various materials over a core material, such as foam or wood, using monocoque or cap ski shell designs, which are costly and labor-intensive processes. Other ski designs contemplating the use of plastic materials have not found commercial acceptance.

  • the device mold may provide for one or more fasteners, e.g., screws, to be partially integrated into the device to enable various bindings and/or boots to be used with device.
  • the device may be a hard-pack ski in which the ski is manufactured using an injection molding process in which the mold provides for the integration of edges along both sides of the ski and a plurality of fasteners in the top of the ski to enable the secure connection of various bindings or boots to the ski that provide high ankle support for the user.
  • the ski can be formed by injecting Ultra High Molecular Weight Polyethylene (UHMWPE), other thermoplastic or a similar material with proper viscosity and attributes for use on snow and in a variety of temperatures using steel edges on both sides of the ski and threaded insert fasteners, e.g., screws, to secure bindings or boots.

  • the mold may include one or more edge portions, magnets or related retention devices to receive and retain corresponding edges and one or more fastener portion to receive and retain corresponding fasteners depending upon the design of the device.
  • the desired number of edges and fasteners Prior to formation of the device structure, the desired number of edges and fasteners are placed into the respective edge and fastener portions of the mold. After the edges and fasteners are placed into the mold, the material that is being used to form the device structure is introduced into the mold.
  • the mold With injection modeling, the mold includes an injection port through which an injection machine is positioned to inject the material into the closed mold.
  • the injection systems may employ a hot runner system to maintain the material within an appropriate temperature to achieve a desired cycle time and material consistency of the finished structure.

  • a cover cooperates with the device such that the cover captures one of the front tip or backend of the device and covers the sliding surface of the device as the cover is being installed and captures the other of the front tip or back end of the device to secure the cover.
  • the cover may be constructed from a hard rubber, silicon, etc, e.g., 50A+ hardness or similar for durability, elasticity and strength, having a front section that captures the front tip of a hard-pack ski and a back portion that may be stretched over the back end of the ski to secure the cover over the sliding surface and the front tip and back end of the sliding device.
