Description
CROSS REFERENCE TO PRIOR APPLICATION

This application is a National Stage Patent Application of PCT International Patent Application No. PCT/KR2013/010364 (filed on Nov. 14, 2013) under 35 U.S.C. §371, which claims priority to Korean Patent Application No. 10-2012-0128591 (filed on Nov. 14, 2012), which are all hereby incorporated by reference in their entirety.


BACKGROUND

The invention relates to a snow sliding apparatus, and more specifically, to a snow sliding apparatus which slides on the snow surface and enables the user to implement more various techniques.


Ski and snowboard represent the sports using the tool enabling sliding on the snow surface. The user puts his feet on each of the skis and controls the direction by using the ski and ski sticks while the snowboard is an apparatus, where the user puts his both feet on a single deck to snowboard.


Also, pieces of equipment have been developed and used recently, where the user puts a short device on his both feet like a ski board without ski sticks.


Among these, the aforementioned short pieces of apparatus like snowboard and ski board have gained a lot of popularity because they enable the use of more various techniques.


Thus, in the case of snow sliding apparatus, it is required to have a relatively short braking distance on the snow surface while enabling the implementation of various techniques.


SUMMARY

The present invention is to solve the problems with existing technologies and aims to provide snow sliding apparatus that enhances braking performance on the snow surface and enables the user to freely control the turning force via enhanced braking performance.


As described above, the snow sliding apparatus of this invention is expected to have the following effects.


In the present invention, the first concavo-convex part that is formed on either side of the nose or the tail of the snow sliding apparatus is used to easily control the degree of friction against the snow surface and the user of this snow sliding apparatus is expected to implement various techniques and have a short braking distance.


Especially, the performance of this snow sliding apparatus can be enhanced because the user can easily control friction against the snow surface by using the first concavo-convex part, more freely control the turning force, and implement more various techniques.


And when the first concavo-convex part is formed on both ends of the nose and the tail of the snow sliding apparatus, same techniques and brake functionalities can be used regardless of directions, which gives more freedom in using the snow sliding apparatus.


Moreover, in the present invention, the user can use advanced techniques more easily and safely because he can ride on objects like handrails or rails by using the first concavo-convex part of this snow sliding apparatus.

DETAILED DESCRIPTION

Hereinafter, specific embodiments of the snow sliding apparatus of this invention shall be explained in detail by using the attached drawings.


In FIG. 1, the configuration of the preferred embodiment of the snow sliding apparatus is illustrated in the perspective view. The configuration of the invention embodiment is illustrated in FIG. 2 in the base perspective view.


As shown in these figures, the snow sliding apparatus in this invention enables the user to easily slide on the snow surface and easily turn, brake, and implement various techniques while gliding.


As shown in the FIG. 1, the body (11) of the board on the top plate forms the exterior and skeleton of the snow sliding apparatus in this invention. The body (11) can be made of diverse materials like wood, metal, or alloy and it can be made to extend in one direction in parallel or the center part can be made to bend upwards.


The preferred shape of the body (11) is the one that extends in one direction and has a smooth exterior surface that allows the user to use the lower surface to slide on the snow surface.


The body (11) has the nose (18) and the tail (18) on both ends in a longitudinal direction. The nose (18) and the tail (18) are located on the front and rear parts of the body, respectively, and they are bent and extended in a direction that is away from the ground surface.


The lengths of the nose (18) and the tail (18) and the distance between one bent part to the ground may differ from each other but since the overall shape is similar, same reference numbers are given in this embodiment and explanations are given based on the nose (18).


As the nose (18) and the tail (18) are extended to the bent direction from the body (11), the snow sliding apparatus can be prevented from burrowing into the snow surface and the user can implement diverse techniques regardless of gliding directions.


The top side of the body (11) is equipped with the projected rail (20). More specifically, the projected rail (20) is formed as the body (11), the nose (18), and the tail (18) are projected upwardly from the top side. The binding hole (25) that allows the coupling with the binding (not illustrated) is formed on the top side.


The projected rail (20) is protruded from the body (11) and enables the user to glide in a space above the ground surface. This allows the user to elevate the center of gravity from the ground and implement various techniques by freely gaining the turning force.


Moreover, the multiple binding holes (25) are formed on the projected rail (20) in a specific interval so that the user can adjust the positions where he wears the binding and boots. As the projected rail (20) itself serves as a rib to strengthen the durability of the body (11), the overall strength and durability against bending of this snow sliding apparatus can be improved.


In this embodiment, two projected rails (20) are formed side by side on the body (11). To be more precise, both ends of the projected rail (20) are extended to reach the projected portion (31) of the first concavo-convex part (30), which will be explained below. Therefore, the space between the pair of the projected rails (20) is lower than the adjacent area and may have the convergence portion (33) of the first concavo-convex part (30), which will be explained later. In this case, while the user is gliding, snow will flow in between the pair of projected rails (20) and flow out to the rear.


The first concavo-convex part (30) may be formed on one end of the nose (18) or the tail (18). The concavo-convex part is formed to have the part of the nose (18) or the tail (18) converge into the inner part, which allows the user on this snow sliding apparatus to have a greater friction force and a turning force, use more various techniques, and have a shorter braking distance.


In the present embodiment, the first concavo-convex parts (30) may be formed on the nose (18) and the tail (18) or the first concavo-convex part (30) may be formed on either of the nose (18) or the tail (18). Since the first concavo-convex parts (30) on the nose (18) and the tail (18) have similar shapes, they are described herein based on the first concavo-convex part (30) formed on the nose (18).


The first concavo-convex part (30) includes the convergence portion, where the part of the nose (18) or the tail (18) converges into, and the projected portions (31) that are protruded on both ends of the convergence portion (33). In other words, the convergence portion (33) is located between the pair of the projected portions (31) and the convergence portion (33) and the projected portions (31) are formed in a way that makes the exterior a continuous curve.


The convergence portion (33) enables the user to implement more various motions and techniques because it broadens the area of friction against snow during sliding via the form converged into the inner side, facilitates the discharge of the rubbed snow between the convergence portions, and helps the user insert an object in between the convergence portions (33).


In order to maximize such functionalities, the preferred location of the convergence portion (33) is in between the projected rails (20). The convergence portion (33) is connected in the space between the projected rails (20), which are lower than the adjacent area, to freely discharge the rubbed snow.


That is, in a normal snowboard, the size of the side cut that converged into the side determines a turning radius while in the snow sliding apparatus but in this invention, the user applies forces to the nose or the tail while sliding and the forces are given to the snow surface, making the projected portion (31) or convergence portion (33) rub the snow or break the snow on the friction side instantly, which would elevate resistance and maximize the inertial turning force or performance by speed control and braking.


As seen in FIG. 5 illustrating the cross-sectional view about the I-I′ line of FIG. 4, the slope part (33′) is formed on the exterior of the projected portion (33). This makes the exterior of the projected portion (33) face the snow surface via the slope part (33′) to facilitate friction between the snow sliding apparatus and the snow surface. In this embodiment, the slope part (33′) is inclined upwards but the tilt angle of the slope part (33′) may vary according to conditions or purposes.


In the present embodiment, one convergence portion (33) is formed in the nose (18) but as shown in FIG. 6 (a), the first concavo-convex part (30) may have two or more convergence portions on the nose (18) and the forms may vary as seen in FIG. 6 (b).


In the meantime, the preferred length of the body (11) is 40 cm˜70 cm and the preferred height of the bent end of the nose (18) and the tail (18) is 1.0 cm˜4.0 cm. If the body (11) is longer than 70 cm, the snow sliding apparatus may not perform as a ski board and if the distance between the ground and the bent ends of the nose (18) and the tail (18) is 1.0 cm or shorter, the nose (18) and the tail (18) may burrow into the snow surface and if it is 4.0 cm or higher, it is difficult for the first concavo-convex part (30) to have friction against the snow surface.


Moreover, it is desirable to have the body (11), the nose (18), the tail (18), and the first concavo-convex part (30) in one piece made of metal. Metal materials with a very low coefficient of elasticity and high strength are recommended.


The FIG. 9 shows how the snow sliding apparatus of this invention is used on the snow surface. Binding and boots are coupled with the snow sliding apparatus but they are not illustrated in this figure.


Thus, the user of the snow sliding apparatus can create friction with the snow surface by tilting either side of the nose (18) or the tail (18) towards the snow surface while sliding on the snow surface and in the process of it, the first concavo-convex part (30) increases friction against the snow surface to improve brake performance or enhance the turning force, allowing the implementation of more various techniques.


Especially, the friction by the first concavo-convex part (30) allows the user to brake in a sliding motion towards the longitudinal direction of the snow sliding apparatus without having to turn the snow sliding apparatus to make the longitudinal direction lie at right angles to the sliding direction to stop sliding.


Also, when an object is used, the user can insert the concavo-convex part (33) between the objects to slide, making the implementation of techniques safer and clearer.


It is evident that the right of this invention is not limited to the explained embodiments and is defined in the claims and the person who has common knowledge in the area of this invention can make transform and modify the apparatus in many diverse ways within the scope of the right stated in the claims.


In the embodiments, putting two pieces of snow sliding apparatus on both feet of the users is taken as an example but this invention can apply to the case where the user puts both feet on a single deck.


For example, as shown in FIG. 7, the body (11) may have the second concavo-convex part (28) in addition to the first concavo-convex part (30). The second concavo-convex part (28) is formed when the side of the body is converged and as illustrated, it may take a circular arc or a semicircular shape or a triangular or a tetragon shape.


When the second concavo-convex part (28) takes the form of a circular arc or a semicircle, it is desirable to make it part of a virtual circle or semicircle with the radius of 30 cm˜80 cm.


This kind of the second concavo-convex part (28) is formed on at least one side of both sides of the body (11) to allow the user to insert the object in the second concavo-convex part and implement more various techniques.


Also as illustrated in FIG. 8, the dummy spacer (40) is selectively coupled with the first concavo-convex part (30) to fill the convergence portion (33) and the corresponding coupling piece (43) and the coupling slit (34) are formed and pressed in the inner side of the dummy spacer (40) and first concavo-convex part (30). Though not illustrated, the dummy spacer (40) can be coupled with the first concavo-convex part (30) by a separate fastener. The second concavo-convex part (28) can also be filled selectively by the dummy spacer (40).


Since the first concavo-convex part (30) and the second concavo-convex part (28) can be selectively filled by the dummy spacer (40), the user can use the functionalities by using the first concavo-convex part (30) and the second concavo-convex part (28) or use it as a normal snow sliding apparatus by coupling it with the dummy spacer (40).


It is desirable to have the front side of the dummy spacer make a continuous flat surface to the exterior of the body adjacent to it and form a smooth exterior without a trace of the first concavo-convex part (30) or the second concavo-convex part (28). This is to ensure the functionality as normal snow sliding apparatus when it is coupled with the dummy spacer (40).
