Ski having front and rear protective mechanism

Abstract

A ski includes a ski main body and two shock resistant protecting plates attached to front and rear ends of the main body. The protecting plates are made of material having high structure strength and high hardness. The ski main body forms a front mounting slot and a rear mounting slot. One protecting plate is mounted in the front mounting slot with an outer portion thereof extending out of the front mounting slot, and the other protecting plate is mounted in the rear mounting slot with an outer portion thereof extending out of the rear mounting slot. The provision of the protecting plates improve shock resistance of the ski. The protecting plates are assembled to the ski main body using special method to form a united member, thus providing the ski with both good appearance and high shock resistant, and can be employed in skis of any kind and specification.

1 . A ski having front and rear protective mechanism, comprising a ski main body and a pair of shock resistant protecting plates attached to front and rear ends of the main body, the protecting plates being made of material having high structure strength and high hardness, wherein the improvements comprise that: the ski main body forms a front mounting slot and a rear mounting slot at the front and rear ends thereof, respectively; one of the protecting plates is mounted in the front mounting slot with an outer portion thereof extending out of the front mounting slot; and the other of the protecting plates is mounted in the rear mounting slot with an outer portion thereof extending out of the rear mounting slot. 
   
   
       2 . The ski having front and rear protective mechanism of  claim 1 , wherein an underside of a part of each protecting plate that extends out of the mounting slot protrudes so as to form a step thereon, and the step is coplanar with a bottom surface of the ski main body. 
   
   
       3 . The ski having front and rear protective mechanism of  claim 2 , wherein the ski main body includes, from bottom to top, a bottom plate, a lower fiber glass layer, a core plate, an upper fiber glass layer, and a panel, which are laminated together in that order; a cutout is defined in each of front and rear ends of the core plate; the cutout has a shape such that outer edges of the front and rear ends matching with inner edges of their corresponding protecting plates; the front and rear ends of the core plate, the lower fiber glass layer, and the upper fiber glass layer, cooperatively form the mounting slots at the front and rear ends of the ski. 
   
   
       4 . The ski having front and rear protective mechanism of  claim 3 , wherein the front and rear ends of the bottom plate respectively abut against inner sides of the steps. 
   
   
       5 . The ski having front and rear protective mechanism of  claim 1 , wherein rubber films are attached to top and bottom surfaces of a part of each protecting plate that is received within each mounting slot. 
   
   
       6 . The ski having front and rear protective mechanism of  claim 3 , wherein the ski further includes side steel frames disposed at two opposite sides of the bottom plate, rubber strips disposed between the bottom plate and the lower fiber glass layer, ABS strips disposed at two opposite sides of the core plate, and screws fastening the bottom plate with the core plate, and screw washers are attached around the screws. 
   
   
       7 . The ski having front and rear protective mechanism of  claim 6 , wherein the screws and washers are hexagonal head screws and hexagonal washers. 
   
   
       8 . The ski having front and rear protective mechanism of  claim 1 , wherein the protecting plates on the parts extending out of the mounting slots form marks or notes.
