Description

Snowboarding {SNOWBOARD}

The invention relates to a snowboard comprising a partitioned sliding surface and an exchangeable web, as defined in claim 1.

Recently, various snowboard solutions have been developed, which are not only related to the shape but also to the technical features of the snowboard. Various designs relate to one-piece snowboarding and partitioned snowboarding.

The divided snowboard design requires improvement in terms of the support structure and flexibility of the snowboard, in particular. It is generally known that the flexibility of snowboards has a significant impact on riding quality and depends on run characteristics. In addition, the turning / cornering characteristics of snowboards can be predicted through a "parabolic" design.

The flexibility of the snowboard in the vertical direction, that is, the flexural strength that the snowboard exhibits during the vertical movement of its long axis, has a significant effect on the riding quality. When the snowboard is placed flat on the snow and slides in the longitudinal direction, the flexibility of the snowboard should be bent upwards when compared to the middle of the board, when the board is in the trough, and the snowboard is convex. When jumping over a place or high, both ends show a counter flex

Another important factor governing the nature of snowboarding is the "twistability" of the snowboard in the torsional stiffness or long axis range. This property affects the smoothness of weight transfer during riding and turn (how quickly the rider switches from one edge of the snowboard to the other).

In short, the characteristics of snowboarding during the turn are influenced on the one hand by the torsional stiffness or "torsion" described above, and also through the parabolic shape of the snowboard-the middle region of the board is significantly smaller in width than the end- Affected and on the other hand, the flexibility of the "inside" edge of the snowboard. During the turn, the snowboard is edged or placed at an angle. That is, while the outer edge is nearly away from the eye, the side curve is tilted such that only the inner curve long axis edge of the board is substantially in contact with the eye.

DE 201 13 739 U1 discloses a snowboard with a one-piece body, where the body comprises a slit that extends essentially along the long axis from the rear end to the middle region. This has the effect of creating two blades that are partially separated from each other and are connected through the one-piece front region of the snowboard body. This slit divides the sliding surface of the snowboard into two separate gliding surfaces that can have a positive effect on gliding resistance. However, the shape of a typical snowboard is modified because the parabolic curvature of the middle region of the snowboard, thus negatively affecting turning capability, is significantly reduced.

DE 198 20 619 discloses a snowboard with divided sliding surfaces which improves the pressure distribution characteristics of the snowboard and thus tends to allow for sensitive and controlled snowboard riding. The problem with this solution is that the split sliding shape must be interconnected for some degree of action that does not interfere with the motivated advantage. This goal is probably achieved due to the provision of a damping spacer fixed between the spring and standing plate and the sliding surface on both sliding parts. This kind of connection requires a fairly technical and economical point of view, and different types of boots bindings, which are different from normal bindings and have complex structures.

Utility model application DE 203 06 244.2, published as EP 1615706, also discloses a snowboard with an extended web that is integrated with the divided gliding member and the snowboard and is above the gliding member. These snowboards have a single body and the design does not allow for the combination of various snowboard geometries and the various materials of the snowboard and the web.

It is an object of the present invention to provide a snowboard comprising a segmented gliding surface, which snowboard provides improved riding quality on downhill and curves, and provides structural and manufacturing flexibility, including shape.

This object can be achieved by the present invention as defined in claim 1. Specific embodiments and advantageous features are defined in the dependent claims.

1 is a side view according to an embodiment of the present invention;
FIG. 2 is a perspective view of the snowboard of FIG. 1 with a separate long axis web (stringer); FIG.
3 is a snowboard without a web, another embodiment of the web and a perspective view with such a web mounted on a snowboard,
4 is a perspective view of a snowboard equipped with ski boots, and
5 is an enlarged partial view of FIG. 4.

The present invention is based on the actual tested characteristics of existing snowboards. In other words, the overall shape and manufacturing process of existing snowboards should be maintained as far as possible, but the performance in use is significantly improved compared to known solutions.

According to the present invention, a snowboard having the same basic body as an existing snowboard is provided. Such bodies include slots (empty spaces) that are approximately 8-10 cm wide and 70-80 cm long. The snowboard includes a long axis web fastened to the body during use, the web not in contact with the ground, ie the slope. This means that the long axis web is arranged at a predetermined distance from the body.

The measurement clearly makes it possible to dimension and motivate riding quality according to the snowboard of the present invention. The web, such as the leg on the trench, extends over the slot and engages the front and back portions of the snowboard.

Preferably, it is possible to use threaded connectors ("inserts") to provide snowboards that include webs of various shapes and properties. As usual, the binding mount is placed on the web in the center of the snowboard. This results in the snowboarder's feet on the snow surface approximately 2 to 5 cm above, the height being established corresponding to the spacing element. The presentation of an exchangeable web not only allows many designers to create their own, but can also satisfy the tastes of individual users. For example, the web can be made differently from a lighter material than the rest of the board. In this way, the need for a lightweight structure can be considered. To some extent, the web constitutes the "heart" of a snowboard. It is possible to manufacture the web from various materials with different characteristics / strengths according to the user's preference. Thus, proper web selection has a positive effect on the overall board.

In one aspect according to the present invention, there is provided a snowboard comprising a main body and an exchangeable web. The board includes a side sliding portion extending in the long axis defined as a sliding surface of the snowboard and a standing surface formed by a high long axis web in the center.

In a further improved aspect of the invention, the sliding portion and the long axis web of the board are designed and fastened so that the web can extend on a threaded hole (insert) at the front or the rear of the board. Thus, several parts (two or more parts) of a snowboard are provided, including a divided gliding surface.

In particular, it is important that the snowboard of the present invention emphasizes or includes the advantages of one-piece snowboarding. This means that the width of the snowboard according to the invention corresponds with the width of the existing snowboard in the front and rear areas. Within the scope of the present invention, the snowboard comprises a waistline in the middle region, which waistline is formed through an appropriate shape of the long axis of each sliding portion.

While the lower side of the sliding portion appears as a sliding surface of the snowboard, the long axis web is defined as a standing surface for the snowboarder. The standing surface comprises suitable means such as, for example, an opening (insert) for attaching a commonly available binding. The long axis webs are preferably arranged at a distance of 2 to 5 cm from both side sliding portions including sliding surfaces extending in the full width front and rear sliding areas of the snowboard.

The presentation of snowboards, including interchangeable, high-length webs, has the following important advantages:

The transfer of force from the point of the user's foot and heel to the sliding surface through the spacer is much more accurate than with conventional snowboards. In this way, the board of the present invention allows for better carving and sharp turning. The height of the standing surface allows for easy riding and also, due to better means, the riding comfort is improved.

In addition, the snowboard of the present invention presents enhanced flexibility due to the use of various materials, due to the special structural features and in part the use of other materials for the web than for the rest of the snowboard. The modification and enhancement of the torsional stiffness of the snowboard due to the presentation of interchangeable webs (with various materials, structures and specifics) also have a positive effect on the quality of the snowboard riding. Products (snowboards) can now satisfy customers' tastes to a great extent. The snowboard structure of the present invention, as described above, provides a reduction in the gliding resistance of the snowboard achieved through a divided sliding surface made as a separate member and an exchangeable web.

The high placement of the long axis webs not only results in improved flexibility of the snowboard, but also provides an improvement in motion (ride), especially when turning curves. The vertical distance between the web and both side gliding portions or the distance between the binding and gliding portions can be adjusted by various means. For example, the height can be adjusted with spacers fastened on the upper surface of the sliding portion in each boot binding area. The thickness of the spacer determines the vertical difference, or height, between the sliding portion and the web.

In another embodiment of the binding mounted on the web, the spacer may be mounted to the sliding surface or engage with the boot binding in a detachable, movable or adjustable manner. Another possibility to bear the height between the web and the sliding surface is to include the web or incorporate the spacer on the web. This possibility is almost endless.

When snowboarding is used (eg on the slopes), in any case for optimum power transfer from the feet, especially at the tip of the foot and the heel to the gliding surface, spacers are used for boards and bindings, especially at the tip and heel of the user's foot. It is strongly recommended to adhere firmly at. This ensures that when pressure is applied to each sliding surface by the tip of the foot, the coexisting pulling force is applied by the foot to the other sliding surface and vice versa. This has the effect of strengthening the so-called "grips" of the snowboard on the slopes.

As mentioned above, the spacers can be arranged in various ways on their contact surfaces in the range of binding, heel and toe, and can also be joined or integrated into the web. In all cases, the height of the spacer corresponds to the height (height difference) between the long axis web and the sliding portion of the snowboard.

The present invention is intended to meet the stubborn needs or desires of snowboard riders in various foot positions, ie regular or so-called "goofy" riding. In addition, the snowboard of the present invention allows for improved stability and enhanced pressure on the sliding surface.

According to the invention, the variability of the foot position of the snowboard can be achieved by the provision of a guiderail / insert on the web or in the web along the length of the snowboard. This then provides an adaptable boot binding along the guide rail in the direction of the snowboard long axis.

The multi-piece design of the snowboard of the present invention also provides advantages with respect to the manufacture of the product. Snowboards, including sliding surfaces, may be made of known materials such as metals, plastics, polymer fibers, various kinds of natural fibers, Kevlar, aramid fibers, other synthetic materials, or any suitable known or newly developed materials. Can be.

As a replaceable element of the snowboard, the web can be manufactured in a separate process and can also be made by setting different materials as well as known materials as well as individual boards. This can lead to an improvement in the advantages already described above with regard to riding quality.

For users who want a snowboard that is different from the ones already determined (e.g. soft, hard, turn familiarity, plus aggressiveness), there is no need to buy another snowboard, but instead it is required by the snowboard. You just need to buy a new web that will give you the features. Therefore, it can be reused in part. The material can be selected not only in accordance with the technology but also in accordance with economic considerations.

In short, the present invention provides a snowboard that presents reduced resistance between the gliding surface and the snow, improved flexibility, torsional stiffness and enhanced riding smoothness.

The snowboard of the present invention is suitable for various snowboard types, namely racing boards, all-round boards, and boards (with suitable width) or webs and snowboard bodies used for deep snow and It combines with the properties of so-called "fun park" snowboards, which make a choice of materials.

The invention will be explained in more detail by way of example in conjunction with the drawings.

Like the overall snowboard 1 clearly seen in FIGS. 1 and 2, the snowboard is a multi-piece assembly. There are two sliding parts 2, 3 arranged on the side along the length of the snowboard 1. The sliding parts 2, 3 are separated by a predetermined distance. When the snowboard is fastened to the snowboard 1 via the connecting means 13, the snowboard extends from the front region 5 to the rear region 6 of the snowboard 1 and a vertical separation of up to 5 cm is provided in the web and It further comprises an exchangeable long axis web 4 formed to be produced between the upper surfaces of the sliding parts 2, 3. The sliding parts 2, 3 comprise concave bends at their outer edges, which bends form the waistline (parabolic shape) 9 of the snowboard 1. The top surface of the replaceable long axis web 4 is provided as a standing surface 12 (FIG. 4) for a snowboarder. A threaded hole (insert, 7) is provided in the area for mounting the boot binding, which is supported in the hole 7. Near the hole 7, a spacer 8 is arranged in the switching direction of the snowboard 1. The spacer can be mounted on the upper surfaces of the sliding parts 2, 3 as height adjusting elements as shown in FIG. 2. Alternatively, they can be combined with a binding and can be combined or integrated into an exchangeable web 4.1, as shown in FIG.

In this embodiment, the toe and heel of the snowboarder are held and supported on the spacer 8. This arrangement ensures that the rider's foot movement is transferred directly onto the sliding portion of the snowboard 1 and avoids inadvertent tilt movement.
