Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a slide board, that is, sports equipment that allows a board user to slide down a slope. Such slide boards are commonly known as snowboards. However, the use of the slide board is not limited to snow or artificial snow, but can be used on other prepared slopes.

[0002]

[Prior art]

 Slideboards or snowboards are known in the form of substantially flat plates having a constricted outer edge and upwardly curved front and rear portions. At this time, the downwardly facing slide surface is formed flat and has no structure. The slide board is somewhat flexible and is steered by the application of a load on one side, with the outer edge narrowed as the board bends.

[0003] Such a slide board has high demands on the traveling skill of the board user, and is not suitable for children and those who are not good at sports. This is further enhanced by a maneuvering mechanism that produces a drift movement when traveling on a curve, ie, a velocity component that is transverse to the board direction. Because of this, a large lateral force is generated, so that all of the known slide boards are provided with retaining devices, similar to foot rings or ski bindings, for special shoes. Thereby, the board user is "tied" to the board to some extent. Therefore, the board user cannot easily change the position of his feet on the slide board or drop his feet on the ground to support it when stopped or running slowly. Some training of the slide board and a good sense of balance are needed to keep it from falling when running or stopping.

[Problems to be solved by the invention]

 The problem underlying the present invention is to provide a slide board that can be used by children, untrained people or poor sports people.

[0005]

[Means for Solving the Problems]

 According to the present invention, the object is to provide an upper tread surface and a lower slide surface, wherein the slide surface extends in the traveling direction and protrudes downward, and both sides of the slide structure as viewed in the traveling direction. And at least one guide structure extending in the traveling direction and projecting downward, the guide structure being convexly curved with respect to the slide structure, and being lower than the slide structure. This is solved by a slide board with a short protrusion length.

In the case of this slide board, the purpose of the protruding central slide structure is to enable straight running without braking and thus to be able to be used even on gentle beginner slopes. Therefore, the slide structure must be designed to support the slide structure alone on at least some hard ground when the slide board slides down straight or when a load is applied in the center. In doing so, the shape of the sliding structure should be such that the sliding resistance is as small as possible.

For this purpose, the slide structure has a structure similar to skis. In a preferred embodiment, the ski-like structure comprises at least one longitudinally extending concave recess and a straight sliding surface with edges on both sides of the recess. In view of the sliding properties and the required support surface, a slide structure that is not too wide extends over the entire length of the slide board.

[0008] On the other hand, the lateral guide structure has a function of causing the slide board to run on a curve when a load is applied to the side and the slide board is tilted. For this purpose, in the present invention, the guide structure does not protrude downward than the slide structure, and is formed so as to be convexly curved with respect to the slide structure. On hard terrain, the maneuvering motion corresponds to the tilt of the slide board about the longitudinal axis, which results in contact of the guide structure with the ground, which in turn influences the sliding characteristics due to the curved shape of the guide structure, which leads to a curving run. It becomes possible. On non-rigid ground, this tilting movement corresponds to a change in the transfer of relative forces to the slide and guide structures.

The guide structure has as good a guide characteristic as possible, in particular a “grip”, and should not have its supporting or sliding characteristic when sliding down a straight line, so that a simple and advantageous implementation is possible. In shape, it is formed as a simple narrow cross-sectional profile, ie, a rail projection. In principle, a plurality of guide structures can be provided on each side of the slide structure, but the slide surface of the slide board as a whole does not have a distinctive structure in consideration of the linear sliding characteristics. Should be so. Therefore, an advantageous compromise between linear sliding properties and predetermined maneuverability is to provide only one guide structure on each side of the slide board. The running characteristics are affected by the profile and curvature of the guide structure, in particular by the dimensions of the slide structure projecting below the guide structure. The smaller the difference between the protrusions, the more the linear slide down is braked, and the slide board responds more clearly to the load movement when traveling on a curve. The greater the difference in protrusion, the more the board user is required to have a sense of balance. Of course, the design of the entire sliding surface of the slide board must be elaborated in relation to the respective running ground.

Since the guide structures can be integrally formed so as to be flush with the outer edge of the slide board, particularly in the above-described rail formation, the side surfaces of the respective guide structures are the same as the outer edge. . This not only results in an elegant and uniform appearance due to the constrained inevitable shape of the slide board, but also provides a very good grip when cornering due to the slide board thickness caused by the height of the guide structure. Such a simplified slide board shape also offers manufacturing technical advantages.

The slide board brake device is not essential but important. For this purpose, a braking projection can be provided at the rear of the slide board. In order to optimize the braking effect, the braking projection has a distinct profile and extends transversely to the direction of travel, i.e., transversely to the slide structure. The brake is applied by applying a load to the rear of the slide board when driving. In order to minimize the influence of the braking projection on the linear slide-down, the projection of the braking projection is shorter than the sliding structure. The braking lug is preferably mounted on the upwardly curved portion of the rear of the slide board, so that it only comes into contact with the ground when the slide board is tilted clearly about a horizontal axis.

As is apparent from the above description, the shape of the slide surface is such that the curved running line of the slide board of the present invention is a curved line. The curvature of this curved line lies between the (tight) curvature of the guiding structure, which leads to the curve travel, and the straight shape of the central sliding structure. How much the curving line is inclined relative to one or the other of these two limits depends on the asymmetry of the slide board load applied by the board user.

At this time, in the case of the typical slide board of the present invention, no drift component occurs or only a small drift component occurs. That is, in the case of this type of slide board, the lateral force during traveling on a curve is relatively small. This allows for a very simple control of the slide board according to the invention, especially on non-slip treads on the slide board, without the need for foot rings. As a result, the degree of freedom of the board user when using the board is greatly increased, and the difficulty of learning is greatly reduced, especially for beginners.

In connection therewith, the flexibility and versatility of use are increased. It can sit and lie on a slide board, and can be used like a children's sled. This, of course, simplifies production. This is because non-slip treads can easily be made by appropriate selection of appropriate profiles and slide board materials or by the installation of non-slip tread pads.

An embodiment of the slide board which is simple to manufacture, very easy to handle and good is a blow molded synthetic resin hollow body. The hollow synthetic resin body is preferably provided with a reinforcing web or a reinforcing point for a sufficiently stable hollow chamber structure. In doing so, additional materials, additional processing steps and additional weight of foam material are omitted.

In this context and generally, a suitable material for the slideboard according to the invention is polyethylene.

[Embodiment of the invention]

 Next, a specific embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a bottom view of the slide board according to the present invention. In this case, the front end of the slide board, ie, the front part, is located on the upper side in the figure, and the rear end, ie, the rear part 8 is located on the lower side. Two parallel bands extend from the front to the rear 8 at the center of the slide board. This strip is the slide surface 6 of the slide structure 3 projecting at the center. The slide structure 3 further comprises a concave depression or recess 5 between the slide surfaces 6.

This is clear from the front view of FIG. As shown in FIG. 2, the recess 5 is relatively shallow. That is, the entire slide structure 3 has a depth that is much smaller than the height of the slide structure 2 on the side thereof, that is, the height of the slide structure 3 shifted from the lower surface of the slide board. The slide structure 3 forms a kind of ski with a slide surface having straight side edges extending entirely over the entire length of the slide board.

FIGS. 1 and 2 further show that narrow rail projections 4 as guide structures are provided on both sides of this ski-like slide structure 3 behind the offset portion of the slide surface 2 and on the side edges of the slide board. It is shown that it is provided in. As shown in FIG. 2, the rail projections protrude lower than the slide structure 3 from the displaced portion of the slide surface 2 and, as can be seen from FIG. 1, extend over most of the length of the slide board. , Are convexly curved with respect to the central slide structure.

This convex curvature coincides with the outer contour of the slide board, ie the lateral outer edge 7 (FIG. 2). The guide structure 4 is integrated with the lateral outer edge, that is, formed continuously as viewed from the side. As a result, the entire slide board has a lateral constriction corresponding to the shape of the guide structure 4. FIG. 3 is a side view of the slide board. In this figure, two lines on the left edge of the slide board indicate the difference in the protrusion height of the slide structure 3 and the guide structure 4. The concept of a slide surface simply represents the lower surface of a slide board with a slide structure 3, a guide structure 4 and an intermediate area between them. As can be seen from FIGS. 2 and 3, the front and rear parts 8 of the slide board are bent upward. The bend in the front has a function essentially to keep it from diving on soft ground, for example, deep snow. The bending of the rear part 8 allows the mounting of the braking projection 9 described in FIG. The braking projection extends transversely to the ski-like sliding structure 3, the rear side of the sliding structure being flush with the rear part 8. The brake projection 9 makes little or no contact with the ground during normal driving. The braking projection is only used when the board user applies a load to the rear bent up, causing the board to tilt about its transverse axis and the rear bent up to touch the ground. Furthermore, the upward bending of the front and rear parts 8 is important for certain driving maneuvers. This is important, for example, when a load is applied to one side of the front or rear and used as a pivot point for instantly rotating a slide board.

FIG. 4 is a schematic view showing the cross section of the slide board from the same viewpoint as FIG. In this case, the reinforcing ribs 10 are shown in addition to the details already described. The reinforcing ribs are formed continuously in pairs between the tread surface and the slide surface 2 by appropriate grooves in the tread surface 1 of the slide board. In practice, due to the material thickness being greater than the lines shown, contact or fusion of the groove or reinforcing web with the slide surface 2 occurs near the slide surface of each groove.

This groove is further illustrated in FIG. This is because the groove is exposed and visible from the tread surface 1, that is, the upper surface of the slide board. This results from the manufacture of the slide board shown in the figure by blow-molding a hollow body with polyethylene. By this process, only single-walled features can be manufactured. This corresponds to the successive individual perimeters of the cross section in FIG. In order to cover the reinforcing web exposed on the tread 1, additional work steps are required, which increase the cost and increase the weight of the slide board.

It is important that an exposed groove is provided on the tread surface 1 instead of the slide surface 2 so that the groove does not affect the slide characteristics of the slide surface 2. FIG. 5 further shows contour lines at the front and rear of the slide board. This contour shows the upward bend already shown in FIG. FIG. 5 further shows a tread 11 on the tread 1. This tread consists of a matte, non-slip rubber lining. This rubber lining is bonded to a shallow recess on the tread 1. For this purpose, neoprene or porous rubber can be used as the material. The oval shown at the bottom of FIG. 5 serves for mounting a manufacturer's mark which can be formed as a non-slip tread.

FIG. 4 shows three dimensions indicated by reference numerals d, h, and b. b indicates the width of the tread 1 of the slide board. This width can be narrower than usual, especially when used as a children's snowboard. This width should be specifically adapted to the size of the user's shoe. In particular, it is possible to produce slide boards of different sizes for users of different age groups.

D indicates the “height difference” between the center slide structure 3 and the side guide structure 4, that is, the dimension in which the slide structure 3 protrudes from the guide structure 4. ing. The maximum thickness h of the slide board is the sum of the overall height of the outer edge 7 with the lateral guide structure 4 and the additional “height” d of the slide structure 3. The above features of the slide board according to the present invention are important for the present invention both individually and in combinations different from those shown.
