Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to snow gliding boards, such as snowboards and monoskis, in which both feet are placed on one board and the rider slides on the snow surface.

<Conventional technology> Recently, in addition to traditional skiing, sliding sports on snow have also become popular, such as the use of surfboards at sea.
So-called snowboards, monoskis, etc., in which both feet are placed on wide skis and slide on the snow surface, have appeared and become more diverse.

This type of snow sliding board that has been used in the past has a structure similar to that of general skis, but is simply made with a wider board. Of course, the outer shape of the board was no more than a slight bend in the center and a simple upward curvature (quadratic curve) at the tip.

<Problem that the invention aims to solve> In other words, conventional skis distribute the user's weight between two skis, and the skis have a laminated structure that provides the repulsion and strength associated with this. Of course, it would be impossible to apply this immediately to the structure of snowboards and the like. For example, when riding sideways (when using a snowboard), the board becomes more susceptible to twisting, and in order to cope with this, the looseness becomes weaker and the structure is not designed to provide adequate rebound. Of course, there are also known composite structures for skis that include a reinforced core material in which piano wire or the like is embedded, but the structure is complicated and manufacturing is troublesome. Furthermore, if a snowboard or monoski were simply made with a ski-like bend or side curve, the entire weight of the snowboard or monoski would sink too much into the snow surface, making it difficult to reach high speeds.

In view of the above-mentioned circumstances, the present invention uses a hybrid board with a core material that has great elasticity and shape memory that can handle body weight, and the bottom shape of the board has a structure suitable for snow sliding, such as snowboards, monoskis, etc. The purpose of this invention is to provide a snow sliding board.

<Means for solving the problem> In the present invention, a mesh-woven reinforced glass fiber is layered on the lower surface of an ABS sheet serving as a top sheet to form a top plate part, and an elastic reinforced hybrid is attached to the lower surface of the reinforced glass fiber on the upper and lower sides. A core material formed by sandwiching a reinforcing layer of reinforced glass fiber strands in the longitudinal direction is placed in the middle of the board, and a core material is placed on both sides of this core material.
ABS sidewalls are provided, mesh-woven reinforced glass fibers and P-TEX soles are layered on the underside of the core material and both ABS sidewalls, and steel edges are attached to both sides of the P-TEX soles. The bottom plate is arranged to form a sliding board main body with a composite structure as a whole, and the longitudinal center of this sliding board main body has an arch bend shape, and the top bend is shaped like a ship's bottom with a cubic curve that curves forward and on both sides. It is formed in the shape of a ship's bottom with a cubic curve.

<Function> Due to the above structure, even if a specified binding or cover shoe is attached to the sliding board and riding horizontally or vertically (parallel to the longitudinal direction), the core material itself is extremely strong and resilient. It has a structure that memorizes the bend shape, so it can withstand unreasonable elastic extension, and the top and tail of the sliding board itself have the shape of a ship's bottom, so it can swing left and right and follow irregularities. Become something.

<Example> Hereinafter, the present invention will be described in detail based on the drawings of the example.

1 is the ABS sheet that becomes the top sheet, and
A mesh-woven reinforced glass fiber 2 is stacked on the lower surface of the ABS sheet 1 to form the upper plate part 3, and the lower surface of the reinforced glass fiber 2 is elastically reinforced using special glass fiber, hard urethane, and polymer resin epoxy. A reinforcing layer 6 in which strands of a hybrid board 4 and reinforced glass fibers 5 are laid in the longitudinal direction, and a core material 8 made by sandwiching the same elastically reinforced hybrid board 7 as described above are arranged,
ABS sidewalls 9 are provided on both sides of the core material 8, mesh-woven reinforced glass fibers 10 and a P-TEX sole 11 are provided on the lower surface of the core material 8, and steel edges 1 are provided on both sides of the P-TEX sole 11.
2 is a mounting lower plate part 13, and these as a whole form a sliding plate main body 14 having a composite structure. Furthermore, an arch bend 1 of a predetermined shape is formed in the center of this sliding plate main body 14.
6, a top bend 18 having a hull shape 17 with a cubic curve curved at the front and both sides is formed at the tip which becomes the nose part, and a tail 20 having a hull shape 19 with a cubic curve is also formed at the rear end. Also, side curves 21 are arranged on both sides of the entire board to create a snow sliding board 2.
It becomes 3. In this case, the bottom shape 19 of the tail 20
In addition to the shape of the outer curve 19a as shown in FIG. 2A, the shape may be an inner curve 19b as shown in FIG. 3A. The point is that the bottom of the boat is warped and has a shock absorbing structure that is appropriate for the type of planing.

Next, to explain this effect, first of all, in actual use of this snow sliding board 23, for example, when using a snowboard as shown in FIG. Bindings 24 for securing footwear (not shown) are fixed in a horizontal V-shape. However, one of the bindings 24 is arranged perpendicular to the longitudinal direction of the board.

If the user stands on the pair of bindings 24 in this state, he or she will be riding sideways on the board. Here, the rider slides down the snow surface with a posture similar to that of a surf-in. In this case, when changing the sliding direction of the snow sliding board 23, how to apply the weight of both feet,
This is done by changing the balance, but at this time it depends on the return rebound of the snow sliding board 23 itself and the impact between the top and tail. That is, the core material 8 of the sliding board main body 14 has strong strength (bending, compression, etc.) with no directionality and elasticity, and has a so-called shape memory that immediately returns to its original shape when the weight shifts (floating). To be rich and
The shapes of the bottoms 17 and 19 of the top and tail parts absorb shock and absorb dust, making it possible to smoothly change direction and run over uneven surfaces. Of course, on both sides
It is made of ABS sidewall 9 and steel edge 12, so it is resistant to torsion.

<Effect of the invention> As mentioned above, the snowboard, monoski, or other snow sliding board of the present invention uses a sanderch board, which is an elastically reinforced hybrid board with a reinforcing layer of reinforced glass fiber or high-strength aluminum board, as the core material of the board body. In addition to using a ski structure, the shape of the board body is shaped like a boat bottom with a cubic curve in the top bend and tail, in addition to the arch bend that is inherent to skis, which improves the board's original strong elasticity and resilience. (shape memory) and relief from the bottom shape provide great shock absorption and a vibration-proof structure, allowing for smooth gliding. Moreover, as mentioned above, the front and rear ends of this board are shaped like a ship's bottom, so unlike conventional skis that have a curved quadratic curve, they can fully follow irregularities on the snow and prevent them from digging in. Therefore, you can glide faster and more powerfully. In addition, this core material has a light specific gravity (0.5 to 0.70), and the board itself is not unnecessarily heavy, making it easy to transport and handle, and has practical effects such as good workability. In the above description, snowboards, monoskis, etc. have been described, but the present invention can be applied to various types of boards for the purpose of sliding on snow, such as sled boards.
