The ski main body forms a front mounting slot and a rear mounting slot at the front and rear ends thereof, respectively. The ski main body includes, from bottom to top, a bottom plate 11, a lower fiber glass layer 12, a core plate 13, an upper fiber glass layer 14, and a panel 15, which are laminated together in that order. A cutout 130 is defined in each of the front and rear ends of each core plate 13. The cutout 130 has a shape such that outer edges of the front and rear ends matching with inner edges of their corresponding protecting plates 3. The front and rear ends of the core plate 13, the lower fiber glass layer 12, and the upper fiber glass layer 14, cooperatively form the mounting slots (not labeled) at the front and rear ends of the ski.

The ski further includes side steel frames 16 disposed at two opposite sides of the bottom plate 11, rubber strips 17 disposed between the bottom plate 11 and the lower fiber glass layer 12, ABS (Acrylonitrile Butadiene Styrene) strips 18 disposed at two opposite sides of the core plate 15, and screws 191 fastening the bottom plate 11 with the core plate 13. Screw washers are attached around the screws 191. The screws and washers may be hexagonal head screws and hexagonal washers.
Before assembly, the protecting plates 3 are pretreated so as to form a layer of transparent high temperature resistant protecting film on a surface thereof. As to protecting plates 3 made of metal materials, it is necessary to apply a sandblast to the extending parts of the protecting plates 3 out of the mounting slots. Components of the ski main body are then assembled. Specifically, the lower fiber glass layer 12 and the core plate 13 are laminated on the bottom plate 11, the protecting plates 3 with attached rubber films 4 are disposed in the mounting slots at the front and rear ends of the core plate 13, afterwards, lamination of the upper fiber glass layer 14, the panel 15 and other assembly steps may be performed according to normal assembly procedure. A front portion of the assembled ski is illustrated in
On the parts extending out of the mounting slots, the protecting plates 3 can form various marks or notes 5, such as, for example, trademarks, company logos, individuation characters, thus providing the ski product with individuation, good appearance, and brand advertising effect.
Shock tests have been conducted with regard to the prior traditional ski without protective strips, the traditional ski with wrapped protective strips, and the present ski with front and rear protective mechanism, respectively. The test results are shown in the following table.
It can be seen from the table, the present ski has higher resistance to shock than the prior skis.
It should be understood from the foregoing description that, the present ski employs shock resistant protective plates made of high structural strength and high shock resistance in order to improve shock resistance of the ski. In addition, the ski is manufactured and assembled to ends of the ski main body using special method to form a united member, thus providing the ski with both good appearance and high shock resistant.
Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
