Abstract

A snowboard, in particular for tour snowboarding outside of prepared tracks, consists of several individual bodies (6, 7, 8, 9) of which two sliding bodies (6, 9) which can be used as skis or as ascension aids. The snowboard has a combined binding and joining system for joining the various individual bodies.

Description

Divisible snowboard with binding and connection system

The invention relates to a snowboard, in particular for touring snowboarding on groomed slopes, and to a combined binding and connection system.

In order to be able to move with a snowboard in a similar way to touring skiing outside of prepared downhill slopes and without technical ascent aids, additional ascent means such as short skis or snowshoes must generally be carried. These represent an undesirable additional weight load during snowboarding.

The object of the present invention is therefore to create a possibility for energy-saving movement with a snowboard outside of prepared downhill slopes and without technical ascent aids.

This object is solved by the features of the claims.

It is advantageous according to the invention that the snowboard is made up of several individual bodies, two sliding bodies being designed in such a way that they can be used as skis or ascent aids.

This enables the ascent and descent with both ski-like edge sliding bodies as in touring skiing and descent with the snowboard after assembly of the individual bodies.

It should be noted that a division of a snowboard that is suitable for touring in its longitudinal direction is generally not useful, since the snowboard halves are too wide and therefore unsuitable for ascent and occasional downhill skiing. In order to obtain the final snowboard shape that is suitable for touring, one or more filler pieces / middle parts must first be carried along on the ascent, which must be fitted between the two ascent skis for the snowboard descent. An advantageous embodiment of the snowboard provides that the two sliding bodies are made in ski construction with side steel edges. The middle section has no side steel edges.

A further advantageous embodiment provides that the bending of the sliding bodies in the area of the blades and at the end corresponds to the corresponding bending of the central body or bodies. The bend in the area of the blade is designed to be degressive in its geometric course. After a steep increase in the shovel (similar to a ski) in comparison to snowboards, the bending radius decreases with increasing shovel height.

Furthermore, it is advantageous according to the invention that the waist radii on the ski-like sliding bodies are non-uniform on both sides. The edge, which serves as the outer edge of the snowboard, has a customary snowboard waist. With the less pronounced waist on the opposite edge it is achieved that the mentioned sliding bodies with their blade width are suitable for ascent.

Finally, it is advantageous that the snowboard has at least two middle parts, the joint of which is formed by a cut which runs obliquely from the snowboard surface to the sliding surface. The cutting process takes place at an angle of - 45 ° to -70 °, measured from the sliding surface, with the cutting direction running from the blade side to the sliding end. A flexible additional component can be mounted on the front half of the middle section, which prevents mutual sliding body misalignment.

The binding and connection system has a central function in connection with a snowboard, which is divided in the form described above. This connects the individual sliding bodies to a snowboard and at the same time allows the shoe to be fastened to the appropriate positions on the individual bodies. The geometric overlaps of the shoe positions for touring, skiing and snowboarding, including the ability to mount the components, must cover the binding and connection system according to the invention. According to the present invention, it is advantageous to provide a combined binding and connection system for connecting the individual bodies. This enables a stable cross connection at the snowboard shovel, at both snowboard binding positions and, if necessary, at the rear of the snowboard. The combined binding and connection system has two binding assemblies that connect the individual snowboard parts (single body) in the middle of the snowboard area and at the same time ensure the individual adjustability of the foot position. A connecting element mounted at the end of the snowboard is used only for the connection.

The shape and number of the binding and connecting components used and their total weight must be optimized with a view to economical production. Particular attention should be paid to light binding and connecting parts that can be assembled and disassembled in all weather conditions within the framework of the reliability requirements. The risk of parts being lost during a tour must be avoided. Accordingly, there is a requirement that assembly and disassembly must take place without the use of tools.

A further advantageous embodiment of the combined binding and connecting system provides that the connection of the individual bodies is provided in two degrees of freedom between the button-shaped holding elements with an undercut and T-shaped guide grooves in corresponding connecting / binding elements. The holding elements are mounted on the sliding body surfaces either directly or via adjustment plates. Locking screws are used for complete, form-fitting locking between the individual bodies and the connecting / binding elements.

The invention solves the problem by means of positive connections between button-shaped holding elements and connecting elements which are to be pushed over these holding elements. For complete locking, even in the direction of being pushed open, the connecting elements are clamped to retaining elements with locking screws. The holding elements are permanently attached to the sliding body surfaces or permanently on additional adjustment plates. The adjustment plates are in the area of Shoe positions for snowboarding. They allow individual adjustment of the snowboarder's body position.

Furthermore, standardized connection elements are provided at all connection points between the individual bodies. Two connecting elements additionally carry a binding carrier.

An embodiment of the combined binding and connection system advantageously has a device for blocking the station, which also serves as a climbing aid. The climbing aid is detachably connected to the binding support.

Another advantageous development of the present invention provides that the button-shaped holding elements have a circular profile in plan view and at least one inclined surface in cross section. The sloping surface is used for clamping with the locking screw and the backlash of the assembled individual bodies.

A further advantageous embodiment provides that the button-shaped holding elements do not limit the pushing-on direction of binding or connecting groups in the plane parallel to the snowboard surface. These holding elements form the universal fastening interface between the sliding body and the binding / binding system with a degree of freedom of 360 °.

Another advantageous embodiment provides that locking screws are integrated in the connecting / binding elements, which after manual operation form the three-dimensional positive locking between the connecting / binding elements and the holding elements. The locking screws are manually screwed into the connecting elements via recessed grips until there is no protrusion. This results in a minimal overall height.

Another advantageous embodiment provides that the centers of the holding elements on the edge sliding bodies have the same distance as the centers of the locking screws in the connecting / binding elements. The distance between the holding elements is used to reinforce the clamping effect of the edge sliding bodies with one another can be slightly enlarged on the edge sliding bodies with the distance between the centers of the locking screws unchanged. A connecting element at the end of the snowboard is rotatably fixed in its center on the middle part of the snowboard.

Finally, a further advantageous embodiment of the present connection provides that the individual choice of the snowboard foot position can be adjusted by means of adjustment plates. A standard setting range is provided. The circular guidance of the individual plates, on each of which a holding element is attached, enables the stepless angle adjustment including the goofy and regular adjustment. For fastening the binding supports, the corresponding holding elements on opposite adjustment plates can be adjusted so that they are on a common straight line. Bores and / or longitudinal slots in the adjustment plates for attachment to the sliding body surfaces realize the adjustability of step size and body center of gravity on the snowboard.

A last advantageous embodiment provides that climbing aids, preferably made of plastic, can be fixed in place during the tour ascent. This happens between two button-shaped holding elements approximately in the middle of each edge sliding body. After mounting the binding elements on the holding elements mentioned, there is an ascent aid between the sliding body surface and the underside of the connecting element.

Advantages are thus achieved by the combined binding and connection system according to the invention:

Step width adjustability of the snowboard binding;

Adjustability of the binding position in the longitudinal axis of the snowboard for shifting the center of gravity of the driver-snowboard arrangement; Angle adjustment for each foot / shoe with respect to the cross axis of the snowboard from + 50 ° to -60 ° (including the "goofy and regular positions"),

Adjustment of shoe size and position in the longitudinal direction of the binding. This means that the driver's position can also be adjusted across the snowboard (change of center of gravity in the direction of a side edge); The binding for touring and descending on the skis / sliders is in the usual assembly position for touring skis; Assembly of snowboard bindings with 4x4 fastening system on the binding carrier and connection system according to the invention.

In the following, embodiments of the present invention are described by way of example with reference to the attached figures.

In the exemplary embodiment shown in FIG. 1, the individual sliding bodies of the snowboards 6, 7, 8, 9 are connected at four positions transverse to the longitudinal axis of the snowboard using the combined binding and connection system according to the invention. Enclosed- the snowboard ends are firmly mounted on the edge sliding bodies (skis) 6, 9 round button-shaped holding elements 5 on the sliding body surfaces. On the front and rear middle part 7, 8 of the snowboard, a connecting element 1 is fastened centrally via a holding element 5. These connecting elements 1 have a continuous T-shaped guide groove on their underside, which enables the button-shaped holding elements 5 with the edge sliding bodies / skis 6, 9 to be inserted laterally. The three corresponding holding elements are located on a common straight line orthogonal to the longitudinal axis of the snowboard.

If a locking screw 2, as shown in FIG. 2, is screwed clockwise into the connecting element 1, there is a clamping effect between the locking screw 2 and the holding element 5 underneath. At the end stop, the surface of the locking screws 2 is flush with the surface of the connecting element 1 (no Protrusion of the screw heads). This is a prerequisite for a low overall height of the binding supports. With snowboarding (i.e. after assembling the single sliding body) the distance between the centers of the locking screws 2 in the connecting elements 1 corresponds to the distance between the centers of the ski-side holding elements 5. Due to the conical shape of the holding element surfaces (FIG. 5) and the corresponding shape of the underside of the locking screws 2, the individual bodies 6, 7, 8, 9 are to be positioned next to each other with little play and misalignment.

The binding carriers are used to fasten snowboard bindings / binding parts (FIG. 3). A binding support consists of the connecting element 30 with its T-shaped guide groove, the two locking screws 36 and a binding support plate 31, which is connected to the connecting element 30 by an axis of rotation 32. The axis of rotation allows an angular movement of 0 ° to 90 ° between the connecting element 30 and the binding support plate 31.

The hole pattern 34 on the binding support plate 31 is used for the individual, longitudinally variable fastening of a snowboard binding with 4 x 4 standard fastening. It prevents the freedom of rotation of the binding support plate 31 if its lower component side in the T-shaped recess tion of the connecting element 30 is inserted. Depending on how far the component is pushed towards the tip of the toe, it serves as a height-adjustable climbing aid when climbing with the edge sliders.

The individual adjustability of the foot positions of the snowboard binding results from the use of adjustment plates 4, as shown in FIG. 4. In the exemplary embodiment, two adjustment plates 4 are required per foot position, which are each mounted opposite one another on the edge sliding bodies 6, 9 (FIG. 1). A retaining element 5 is screwed onto the circular-shaped guide of an adjusting plate 4, which allows the angle adjustment including the goofy and regular position by loosening and locking the central screw. The arc radius in the setting plate 4 corresponds to half the distance between the locking screws 2 (Fig. 2). Each of the setting plates 4 can be moved in its longitudinal direction and thus in the longitudinal direction of the snowboard via an integrated hole pattern.

If a connecting element 1 or binding support is pushed over the three holding elements 5 provided for this purpose of the adjacent individual bodies 6, 7, 8, 9 and clamped to the holding elements 5 with the locking screws 2, a stable cross connection of the snowboard is created at this point. Between the front and rear adjustment plates 4 there are two button-shaped holding elements 5 on each ski 6, 9 behind the center of the sliding body. The adjustment range of the adjustment plates 4 in the direction of the longitudinal axis of the snowboard is not affected thereby.

The binding supports 3 can optionally be slid on and locked on the latter holding elements 5 or on the holding elements 5 on the adjustment plates 4 transversely to the longitudinal axis of the snowboard. When mounted longitudinally on the edge guiding bodies 6, 9 for touring and skiing, the clamping between one of the two locking screws 2 with a holding element 5 is sufficient. The respective edge sliding body 6, 9 is therefore not braced when it bends.

If the binding supports 3 are attached transversely to the longitudinal axis of the snowboard, in addition to the connection of the individual bodies 6, 7, 8, 9 to a snowboard, the foot positions for the downhill snowboard are also defined. The play-free attachment of the individual parts to each other ensure the locking with two locking screws 2 in the connecting elements 1 with respect to the corresponding holding elements 5 on the sliding body surfaces.

With a flexible plastic plate 10, which is fixedly mounted on the front middle part 7, the division joint 11 between the two middle parts 7, 8 is covered, as shown in FIG. 6. If the snowboard bends, the plastic plate prevents the height offset between the middle parts. The obtuse cutting angle on the rear middle part 8 forms only a slight sliding resistance while driving.

According to a further embodiment shown in FIG. 7, the middle part 70, 71 has a 2/3 -s- 1/3 division in the longitudinal direction of the snowboard. As a result, the front middle part 70 extends over two thirds of the snowboard length, while the rear middle part 71 extends only over one third of the snowboard length of a snowboard according to the invention consisting of four individual bodies 70, 71, 72, 73.

Fig. 8 shows a variant of the snowboard from Fig. 7, in which only three individual bodies 70, 72, 73 are mounted, i.e. the snowboard is made up of the front middle part 70 and the two lateral ski-working sliding bodies 72, 73. This creates a so-called swallowtail or dovetail board, which is particularly well suited for deep snow descents. If the rear middle part 71 is additionally mounted, the full-surface snowboard according to FIG. 7 is obtained again.
