Description

snowboard

The invention relates to a snowboard with divided sliding surface and an exchangeable web, according to the preamble of claim 1.

In recent years, various solutions have become known, which relate to the shape design, but also to the technical feasibility of snowboards. These changes relate to both conventional one-piece snowboards and split-board snowboards.

In particular, with the formation of snowboards in split design, the supporting structures and the flexibility of snowboards to be improved, it being assumed that the general knowledge that the flexibility of a snowboard has a significant impact on the driving characteristics of a snowboard, this considering the driving on different trained slopes. Furthermore, the characteristics of a snowboard when cornering determined by the sidecut.

The flexibility of a snowboard in terms of its vertical direction, d. H. the resilient resistance that a snowboard opposes in an upward or downward movement of its longitudinal ends, has a significant impact on the handling characteristics. If the snowboard slides longitudinally resting on the snow in the longitudinal direction, must be ensured by a properly sized flexibility that the snowboard in Bodenmulden with both longitudinal ends an upward bend relative to the central region of the snowboard and on humps or surveys performs a certain counter-curvature.

Another significant influence on the snowboard's handling characteristics is the torsional stiffness or "twistability" of the snowboard in the longitudinal extent (torsion) .This size influences, among other things, smoothness and load changes when cornering (flying when driving from one edge to the other edge of the snowboard). The properties of a snowboard when cornering are influenced on the one hand by the winding stiffness or "twistability" (torsion) of the snowboard described above, but also by its sidecut - the middle region of the snowboard usually has a smaller width than the longitudinal ends of the snowboard - and on the other by the Flexibility of each curve-inner longitudinal edge.

When cornering the snowboard is folded, i. tilted sideways, so that practically only the curve-inner longitudinal edge has contact with the snow, while the outer longitudinal edge is lifted more or less far from the snow.

Thus, DE 201 13 739 U1 describes a snowboard with a one-piece board body, in which the board body has a slot extending substantially along its central axis, which extends from the rear end of the board body to at least in its central region and thus forms two separate legs , which are interconnected by the one-piece front area.

The proposed slot divides the sliding surface of the snowboard partially in two separate sliding surfaces, which may have a positive effect in terms of sliding resistance, however, the typical snowboard shape was changed by the waisting of the central region has been significantly reduced, so that this has a negative effect when cornering.

A snowboard with a split sliding surface describes the DE 198 20 619 Al, with which a better pressure distribution curve of the snowboard to be achieved, thus enabling a sensitive and controlled snowboarding.

The problem with this solution is that, of course, the two split sliding surfaces have to be connected for a driving operation so that the desired advantages are also achieved. This is to be achieved by means of a spring and damping spacer element, which is mounted between the base plate and the sliding surface on the two sliding parts. This type of connection is very complex both technically and economically, with this solution, a different type of connection from snowboard to sports shoe is necessary, which differ from conventional Bindungsausfüh- ments and are very complicated in their execution. Thus, the utility model application DE 203 06244.2 or EP 1 615 706 describes a snowboard with divided treads with the formation of a longitudinal web, which is firmly connected to the snowboard. This snowboard is one-piece and does not allow a variation in the shape of the snowboard, as well as the combination of different materials of snowboards and catwalks.

The invention is therefore an object of the invention to develop a snowboard with a split sliding surface, with the driving characteristics when driving straight and drive when cornering and the flexibility of construction and structural design including the design can be improved.

According to the invention, this object is achieved with the features of claim 1. Particular embodiments and advantageous solutions are specified in the subclaims.

The invention is based on the recognition that the proven in practice properties of conventional snowboards in terms of their design, design and the manufacturing process, are largely retained, but the performance characteristics of the snowboard over known solutions to be significantly improved.

Thus, a snowboard was created, which consists of a body that is identical to conventional snowboards. In the middle of the snowboard with a about 8 cm to 10 cm wide and about 70 cm to 80 cm long gap, a free piece formed, to which a connectable to the main body of the snowboard web is arranged the base body, in the shape that this longitudinal web does not come into contact with the driving surface, the runway, when using the snowboard. This means that the longitudinal web is arranged at a certain distance from the main body.

The given dimensions can of course vary according to the snowboard dimensions and the driving characteristics to be achieved. Like the bridge over a ravine, the bridge connects the resulting gap at the front and back of the board. Preferably by a screw connection (inserts), it is possible to connect the same board with webs of different shapes and properties. The binding pickup is located in the center of the board on the bridge as usual. This construction creates a height difference of about 2 to 5 cm to the slope. The resulting height difference on heels and toe to the tread or to the sliding parts of the snowboard is closed by appropriate spacers. The replaceable bridge not only allows a variety of design options. Individual customer wishes can be particularly met with it. For example, the bars can be made of materials lighter than the rest of the board. Thus, the basic idea of lightweight construction is taken into account. The bridge is in some ways the "soul" of the snowboard. Webs made of different materials with different characteristics / degrees of hardness can be used according to the preferences of the snowboarder and have a positive effect on the entire board.

In the subject of the invention is a snowboard, which consists of a base body and an exchangeable web. The board is designed so that it is formed in its longitudinal shape with lateral sliding parts forming the sliding surfaces of the snowboard and centered with a footprint in the form of a raised longitudinal ridge.

It is part of the invention that the sliding parts and the longitudinal web are formed in the board so that they pass in the front and rear of the snowboard over notably inserts in the front piece or tail of the snowboard and fixed. Thus, a multi-piece snowboard (at least 2 parts) was created with split sliding surfaces.

It was particularly important that the created snowboard brings the benefits of a one-piece snowboard to bear or united in itself, so that the widths of the snowboard in the front and rear area correspond to those of a conventional snowboard. It is within the scope of the invention that the snowboard in the central region has a sidecut, which is formed by the longitudinal shape of the two sliding parts. While the lower surfaces of the sliding parts represent the sliding surfaces of the snowboard, the footprint on which the athlete stands for snowboard, formed by the longitudinal web, which is formed with corresponding receptacles, such as inserts, to which commercially available bindings can be attached. The longitudinal web is formed at a distance, preferably 2 cm to 5 cm, to the two lateral sliding parts, so that the two sliding surfaces are formed with their sliding parts, these go into the front and rear full-surface sliding area of the snowboard over.

The formation of the snowboard with a replaceable, elevated longitudinal ridge brings the following significant benefits to bear.

The transmission of the toes and heels to the sliding surfaces via the spacers is much more precise than with conventional boards. The board thus allows a better carving and a spritzigeres cornering. The elevated position allows for easier driving, thereby improving ride comfort (leverage).

Furthermore, the flexibility of the snowboard is increased. This is due to the special construction and the use of different, partly different materials for the production of the web than the rest of the snowboard. The change and improvement of the winding rigidity / twistability (torsion) of the snowboard through the interchangeable web (with its different material structure and properties) also has a positive effect on the driving characteristics of the snowboard. The snowboard can now serve the preferences of the snowboarder diverse. The special construction reduces the sliding resistance of the snowboard. This is, as already stated, achieved by the formation of the split sliding surfaces and the interchangeable web.

The increased design of the longitudinal web requires not only an increase in the flexibility of the snowboard, but also improved handling, especially when cornering. The resulting height difference between the longitudinal web and the two lateral sliding parts or the distance of the bond to the sliding parts can be compensated by various ways. For example, there is a possibility that To compensate for height difference by means of spacer elements which are mounted on the surfaces of the sliding parts in the region of the respective ski boot binding. These spacer elements have a thickness dimension which corresponds to the height difference between the sliding parts and the longitudinal web.

The spacer elements can be arranged in an analogous embodiment of the attachment of the ski boot bindings on the longitudinal web replaceable and displaceable or adjustable on the sliding surfaces or combined with the ski boot binding. Another variant for bridging the height difference between the longitudinal web and the sliding parts offers the possibility to integrate the spacer elements with the longitudinal web or on the longitudinal web. Descriptive ideas are set here no limits.

In all cases, it is advisable for an optimal transmission of power of the feet, in particular on the toes and Fußfersen, on the sliding surfaces that the spacer elements when using the snowboard (eg on the slopes) fixed to the board and the snowboard binding, in particular the toe or heel are connected. This ensures that at z. B. a pressure of the toes on the toe tips facing Gleitflächenseite a simultaneous pulling the heel on the other sliding surface is formed and vice versa. This increases the so-called "grip" - the grip of the snowboard on the slopes.

As already mentioned, the spacing elements can be arranged on the ski boot bindings, on their bearing surfaces in the toe and heel area, in other embodiments, or be connected in combination with the web or integrated on the longitudinal web. The distance measure corresponds in all cases to the height difference between the longitudinal web and the sliding parts of the snowboard.

The present invention uncompromisingly meets the demands of snowboarders and their different foot positions, d. H. riding the "regular" or "goofy" snowboard.

At the same time, when using the snowboard, the pressure on the sliding surfaces is increased and the stability is improved. The variability of the foot positions on the snowboard is also achieved according to the present invention in that guide rails, inserts in the longitudinal direction of the snowboard are provided on or in the longitudinal webs, in which the ski boot bindings are received, which are then adjustable in the guide rails in the longitudinal direction of the snowboard are.

The multi-part design of the created snowboard also creates advantages in terms of its production. Thus, the snowboard can be manufactured with its sliding surfaces from the known materials such as metal, plastic, synthetic fibers, natural fibers of various types of wood, Kevlar, carbon aramid fibers, other composites and reusable materials or materials under development. The web can, since it is interchangeable, are produced in a separate production step, in a separate production phase, of course, from the aforementioned materials, however, in a different material combination than the associated board. This results in the already mentioned advantages for the driving characteristic.

Is there a desire for a snowboard, which should have different driving characteristics than the previously used snowboard (eg softer, harder, more revving, aggressive, softer), so it is not necessarily necessary to buy a new board, but this desire could with the Attachment of a bridge can be achieved, which corresponds to the desire of the user and thus has a positive effect on the board. The Board thus contributes part of the idea of recycling and recycling materials and resources.

Consequently, the choice of materials also depends on the production engineering as well as economic conditions, which positively affect a snowboard.

Overall, a snowboard has been created according to the invention, which reduces the sliding resistance between the sliding surfaces of the snowboards and the runway to be traveled, improves the flexibility, the Windungssteifigkeit / twistability (torsion) influenced and the smoothness of the snowboard is increased. This snowboard combines the characteristics of several snowboard types, ie properties of a raceboard, an allround board, but also a board for the deep snow with appropriate width or a snowboard for the so-called "fun park" with appropriate design (material use of the web or board / slider ).

FIG. 5: a detail view according to FIG. 4.

From the illustrations according to FIGS. 1 and 2, the formation of the snowboard 1 in its entirety results directly and it is shown that the snowboard 1 is designed as a multi-piece snowboard. Thus, the snowboard 1 consists of the two sliding parts 2 and 3, which are formed on the two longitudinal sides of the snowboard 1. The sliding parts 2, 3 have a certain distance to each other. This is formed by the arrangement and design of the exchangeable longitudinal web 4, which extends after installation / attachment via the mounting frame 13 on the snowboard 1 from the front portion 5 of the snowboard 1 to the rear portion 6 of the snowboard 1 and is designed so that the longitudinal web 4 to the surfaces of the sliding parts 2, 3 a certain distance measure, a height dimension of up to 5 cm, has. The sliding parts 2, 3 are executed at their outer edges with an inner curvature, which form the waist 9 of the snowboard 1. The surface of the exchangeable longitudinal web 4 serves as a contact surface 12 (FIG. 4) for the snowboarder, wherein inserts 7 are provided in the area of the ski boot bindings to be fastened, to which the ski boot bindings are braced. In the area of the inserts 7, in the transverse direction of the snowboard 1, there are the spacer elements 8. These can, as Figure 2 illustrates, attached to the surfaces of the sliding parts 2, 3 as height compensation, combined with the binding or, as Figure 3 shows, with the interchangeable longitudinal web 4.1 combined / integrated on the exchangeable longitudinal web 4.1.

The toe and heel of the snowboarder rest on the spacer elements 8 and are supported. This ensures that the foot movements of the snowboarder are transmitted directly to the sliding parts of the snowboard 1 and unwanted tilting movements are avoided.
