SNOW SKI
A sports board comprising a core member and a mounting structure interposed between the core member and an upper layer. The mounting structure defines a region on which the binding can be mounted, wherein the mounting structure comprises a flexible structure with holes that permits the core to flex during use.
Disclosed is a specially-configured board for gliding along terrain. The board can be, for example, a snow ski, water ski, snowboard, and the like. Although described herein in the context of snow skiing, it should be appreciated that a “board” described herein will refer generally to any of these sorts of boards as well as to other board-type devices which allow a rider to traverse a solid or fluid surface.
A multimillion dollar issue for ski manufacturers relates to the problem of securing a binding to a ski. A common method of securing a ski binding is by mounting it directly onto the ski. Such a method has the unfortunate effect of stiffening the ski in the region of the ski binding. In particular, the ski is stiffened in the area underneath the boot of the skier, which can adversely affect the feel and performance of the ski. The stiffening effect is a result of resistant pressure created by the combined effect of the boot and binding during the normal flexing of a snow ski during a turn. The natural flexing of a ski is in this way inhibited, such that it has a negative effect on skiing, more specifically in the turning of the ski—an act achieved by angling the ski onto its side, thus causing the ski by bending to produce an arc.
To improve the flexing of the ski under the region of the ski boot, a flexible intermediate plate is commonly used which flexes together with the ski and is more or less a part of the ski. This intermediate plate is attached by screws or elastic glue, either directly to the upper surface of the ski or via an additional elastic layer, which allows restricted longitudinal movement such that it absorbs the shortening of the ski during flexing. However, the aforementioned methods do not achieve optimal results.
Another method of securing ski bindings is via an intermediate plate. The plate has a lower surface that is mounted onto the ski. The upper surface of the plate is then attached to the ski binding to thereby secure the binding to the ski. Screws are typically used in the mounting process. The screws are fastened onto the binding and onto the wood core of the ski. The screws provide a grip or fastening force that holds the bindings on the ski. The wood core is typically surrounded by an outer shells such as a fiberglass shell. It can be appreciated that it is important that the screws do not rip out of the wood core during use of the ski, such as when a skier exerts the various forces involved with both skiing and possibly falling. The interaction between the screws and the wood cores can result in undesirable effects on the performance of the ski during use.
SUMMARYIn view of the foregoing, there is a need for methods and devices of constructing a ski that prevents an attached binding from exerting unwanted influence on the camber and flex of the ski.
Disclosed is a sports board, such as a ski, having a structure that prevents an attached binding from exerting unwanted influence on the camber and flex of the ski. In one aspect, the sports board comprises a core member; an upper layer positioned on top of the core member, the upper layer forming an upper surface on which a ski binding can be mounted; a lower layer positioned below the core member, the lower layer forming a lower surface for gliding; and a mounting structure interposed between the core member and the upper layer, the mounting structure defining a region on which the binding can be mounted, wherein the mounting structure comprises a flexible structure with holes that permits the wood core to flex during use.
The details of one or more embodiments are set forth in the accompanying drawings and the description below. Other features, objects, and advantages will be apparent from the description and drawings, and from the claims.
With reference to
As known to those skilled in the art, a binding can be used to secure a user's boot to the ski. Any type of binding can be used. The ski 100 can include any quantity of regions for attachment of a binding. The ski 100 includes an elongated base structure, which can be symmetrical with respect to a vertical and longitudinal plane or asymmetrical.
The ski 100 shown in is in the form of an elongated body that extends along a longitudinal direction. The ski 100 can be slightly cambered in a vertical plane. As mentioned, the ski 100 has one or more regions 105 provided to receive the elements for retaining the boot such as the ski bindings. Front and rear portions on either side of the regions 105 form the shovel and heel of the ski. As shown in
In cross section, the ski structure has a central core.
The regions 105 are formed by a mounting structure that is positioned on or within the core 305. The mounting structure can be formed of interconnected or interwoven members, such as threads or cords, that are collectively flexible in nature. In an embodiment, the mounting structure is mesh or wire. The mounting structure can be formed into any shape that corresponds to the desired shape of the region 105. The region 105 is sufficiently large to cover an area that can accept a ski binding. In an embodiment, the region 105 is rectangular. In an exemplary embodiment, the mounting structure comprises a metal screen or wire mesh although the structure can be formed of other materials that are flexible. The mounting structure can be attached to the core 305 in a variety of manners including, for example, staples or glue.
In use, a ski binding is positioned on the top surface of the ski over the region 105. The binding is then secured to the ski such as with screws. The interface between the binding and the mounting structure prevents unwanted influence on the camber and flex of the ski that simply placing flat metal on the core cannot achieve to securely fasten the bindings with screws. The mounting structure holds the binding fast to the ski while still allowing the wood core to flex naturally.
Although embodiments of various methods and devices are described herein in detail with reference to certain versions, it should be appreciated that other versions, embodiments, methods of use, and combinations thereof are also possible. Therefore the spirit and scope of the disclosure should not be limited to the description of the embodiments contained herein.
Claims
