Problems solved by technology

For example, longer skis generally provide greater directional stability and generally provide a more stable gliding surface, but they are generally more difficult to use because they are more unwieldy to maneuver

Example

[0018] Refer now to the figures, wherein like numbers indicate like parts throughout the various figures. FIG. 1 shows a plan view of a snow ski 100 made in accordance with the present invention. The present invention provides a ski having a relatively low swing weight and is therefore particularly suited for snow skis used for backcountry skiing, such as cross-country and telemark skiing. It will be readily appreciated, however, that the present invention may also be utilized for all forms of skiing, including alpine skiing, snowboarding, and the like. The ski 100 shown in FIG. 1 includes a relatively wide front shovel section 102, a tapered waist section 104, and a relatively wide rearward heel section 106. The waist section 104 is adapted to receive a binding (not shown) for securing a user's boot to the ski 100. The tapered planform shown in FIG. 1 provides well-known performance advantages, particularly for turning. However, other planforms are also known and may alternatively ...

Abstract

A core (130, 230) for a gliding board (100) is disclosed having a forward shovel section (132), a middle waist section (134), and a rearward heel section (136). The shovel section and heel section are formed from a lower-density material than the waist section. In a particular embodiment, the core is formed from a plurality of elongate members (112) made by joining low-density wood sections (132, 136) to high-density middle sections (134). The sections may be joined using finger joints (140). A reinforcing member, such as an elongate bamboo member (114), may attach to the elongate members (112). The invention also encompasses skis (100) having such variable density cores (130).

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application also claims the benefit of Provisional Application No. 60 / 527,508, filed Dec. 5, 2003, the benefit of which is hereby claimed under 35 U.S.C. § 119.FIELD OF THE INVENTION [0002] The present invention relates to snow skis and, in particular, to snow ski cores having spatially varying material properties. BACKGROUND OF THE INVENTION [0003] Snow skiing, including downhill skiing, cross-country skiing, and telemark skiing, is a popular and well-established winter sport in the United States and around the world. In recent years, snowboarding has also become very popular as an option to conventional downhill skiing. The design of skis and snowboards has evolved and continues to evolve to enhance the user's fun, safety, and capabilities in practicing the sport. For example, the planform shape, length, and edge design of skis have undergone continuing innovation and improvement. Also, the use of modern materials, including polym...
