Description

The present invention relates to a ski, a method for assembling additional elements, e.g. Ski binding and ski brake, on the ski and a method of making the ski.

Usually additional elements, such as ski bindings and ski brakes, either directly or by means of a binding plate attached to the ski by screwing. This is the bond either screwed directly to the ski or bolted the binding plate to the ski and the binding is mounted on the binding plate.

More recently, along with the spread of carving skis has been used a binding plate for mounting the ski binding found wide application. It has shown that it is advantageous if at least one binding element with respect to the ski body is movably mounted, for example, the bending line of the ski through the binding plate and to disrupt the bond formation as little as possible.

A known binding mounting device is described for example in DE-U-200 12 437. The device comprises a front base plate with a mounting zone suitable for a front retaining element is provided, and a rear base plate having a mounting zone, which is provided for a rear retaining element. The rear base plate has in its lower part a transverse pivot for connection to the ski, around which the base plate can swing freely relative to the ski when installed on the ski. The other base plate has a circuit board, the mounting zone and facilities for a Mounted on the ski, which are intended to firmly attach the board to the ski or in a guide long the longitudinal direction of the ski over a limited Amplitude can slide. The base plates are characterized by a non-expandable or non-stretchable connection connected to each other, wherein the compound is formed is that they themselves recover a relative distance of the base plates from each other and is neutral to a relative approximation of the base plates.

DE-U-200 12 438 describes a similar device, where there the front base plate in its lower part a transverse pivot for connection to the ski that allows the base plate to jump freely relative to the ski when on the ski is installed. The rear base plate has means which are provided to the Base plate firmly mounted on the ski. The base plates are not here by a extensible connection interconnected.

The device described in DE-U-200 13 978 has two transverse pivots each one of the front binding element and the rear binding element assigned. The distance between the two pivots is in the range of 156 to 376 mm.

EP-A-1 175 925 describes an alpine ski with an elongate ski body which is a front ski End, has a rear end and a central area. The ski body consists of a Main core, which covers a running surface of the ski, a stack of sliding and reinforcing layers with two lateral ski edges, with the core itself through a stack of Reinforcement and possibly decorative layers are covered. In the middle area of the Skis is superimposed on the main core an auxiliary core, which in this central area one of the Surface of the ski protruding rib with reduced width forms. On this above Rib is a binding plate by means of two transverse pins, extending through the rib and the Binding plate extend, fastened.

Furthermore, EP-A-1 161 972 describes a ski with a profiled rail system which is at least is provided in the binding area on the ski upper side. The profile rail system exists at least one extending in the longitudinal direction of the rail, which is to attach functional elements, for example a bond or its elements or a binding plate, by pushing on the rail. The rail is molded over several Dowels or dowel sections by a dowel joint or anchoring with connected to the ski body.

All of these known ski and mounting devices for binding assembly have the Disadvantage that the binding plates or binding elements attached by means of aids on the ski which, in particular, negatively influences the bending line of the ski, additional Requires assembly steps, the ski body weakens and is less flexible. This is especially true when using screws, dowels and bolts too.

DE-C-195 27 063 describes a ski in which the ski binding by means of a base / support plate attachable to the ski. The base / carrier plate has in width to each other variable jaws, which by means of clamping edges in a longitudinal groove and on the ski side surfaces engages and thus can be brought into locking position. The Jaws and guide blocks arranged thereon slide in a guide slot and a guide rail of the base plate according to the ski width. A centering of the Base plate and a horizontal clamping action of both jaws is done by a single screw or nut. The disadvantage of this construction is in particular the use a separate binding plate, through which the bending line of the ski body essential being affected. Furthermore, the binding plate projects transversely across the width of the ski body on both sides, so that this construction e.g. when cornering, in particular in connection with carving skis, is disadvantageous because the binding plate is in contact with gets the underground.

DE-C-27 11 199 describes a fastener for a ski binding without use of fixing screws with mounting jaws, which are in the area of the ski side surfaces protrude, in the distance mutually changeable and can be brought into clamping position are and at their free ends to ski directed projections, which in in the Skiseitenflächen intervene longitudinal grooves. Even with this construction stands out Fastening element beyond the width of the ski body, which is in terms of use The ski also disadvantages.

EP-A-0 383 104 relates to a ski with a ski binding consisting of toe pieces and consists of a coupled with this via a link heel holder. front jaw and heel hold are each mounted on a cross-sectionally U-shaped carriage, At the free leg ends inwardly projecting Flunche are attached, which in a ski fest Guide rail are mounted. Also in this case a binding plate is provided, which protrudes beyond the width of the ski body.

DE-A-197 53 451 discloses a fastening system for ski bindings, one with a Has ski-connected retaining element releasably connected to a connected with a ski binding Bonding plate is connected. The holding element is screwed to the ski body and is For example, by means of a dovetail guide with the binding plate connectable. By this construction of the bolted to the ski body retaining element and the thereto Attached by dovetail connection plate is the bending line of the Skis significantly influenced.

The present invention has for its object to provide an improved ski, with which the binding assembly is facilitated and at the same time the properties of the Skis are not significantly adversely affected. Another task of the present The invention is to provide an improved method of bond assembly. These Tasks are solved with the features of the claims.

The invention is based on the idea of a mounting device in the ski body of the ski to integrate, with the ski binding can be attached directly to the ski. For this purpose, the mounting device is formed in principle in the manner of a binding plate and in incorporated the ski body. Accordingly, the ski according to the invention has all Benefits associated with the use of a binding plate on and has the additional considerable advantage that the binding are mounted directly on the mounting device can. These are typically no further aids, such as screws, bolts or dowels required. The width of the mounting device is typically in the range of about 50% to 95%, preferably in the range of about 75% to 90% of the smallest width of the ski body. As a result, especially at Carvingski ensures that no part of Mounting device extends beyond the width of the ski body out and so to an impairment the driving behavior of the ski performs, for example, a part of the mounting device comes into contact with the underground.

In a preferred embodiment, the bond to the mounting device becomes jammed attached. For this purpose, the mounting device at least one in the longitudinal direction of Skis extending undercut groove, but preferably two mutually parallel Grooves that are open on sides facing away from each other. The integration of the Mounting element in the ski body is preferably carried out by a suitable receiving rail is already pressed in the gluing of the ski body or that the core complex of the ski is designed by installing a suitable material so that a suitable guide groove by subsequent milling (for example in the passage) during production of the ski is created.

The choice of material or the material combination for the mounting device, in particular the part of the mounting device in which the groove is formed, should be chosen so that good sliding properties are provided for the binding to be mounted. For example should in a metal formed profile on the binding elements of the integrated Guide member or the groove of the mounting device preferably a suitable thermoplastic, a fiber-reinforced plastic, in particular glass fiber reinforcing Plastic, or have a plastic-coated metallic material. In some cases, it may be preferable to use the guide parts integrated with the mounting device by pretreatment, in particular for the gluing to prepare a for a sufficient integration into the ski body necessary affinity to those in ski construction typically used epoxy resins or Epoxidprepregs provide.

With geometric design of the ski body care should be taken that on the one hand the sliding of the binding parts, in particular as a choice with a ski brake and a connecting tongue between the binding parts, is easy to do and on the other hand, the differential bending stiffness or bending line of the ski is not significantly negative being affected. This danger exists in particular by the typically required Increasing the thickness or height of the ski in the binding mounting area. This will be preferred by a suitable change of the cross-sectional shape of the ski body along the Length of the ski realized.

The longitudinal fixing of the binding parts (jaw and heel part) is preferably carried out analogously to the binding assembly on conventional binding plates, by their integrated leadership allow free bending or flexing. This is particularly advantageous for when Bending the ski through the formation of tie and shoe on the ski this not to be tense, ie not to negatively influence its bending line. When inventive Ski are all variations of "Free-Flex" as possible from the corresponding Binding plate are known. For example, the fixation of the jaw part the binding and a free flexing of the heel part via the connecting tongue with which the Back part is connected to the heel part, possible. Conversely, also the heel part attached and the jaw part to be free to move. Alternatively, it is also possible to bake and To lead heel part movable and the longitudinal fixation on the connecting tongue, for example in the middle of the tongue. The fixation of the respective part with respect possible longitudinal displacements, for example, by a Verrasterung, clamping. Bracing and the like can be realized in the guide in a simple manner.

To mount a binding to the ski according to the invention, first an engagement device the binding, which is engageable with the mounting device, provided. Subsequently, the engagement means of the binding and the mounting device of the ski merged. Finally, the binding to the ski by means of the mounting device fixed. The engagement means of the binding preferably has projections, which are inserted during the merging in a groove of the mounting device. The fixing of the bond is preferably carried out exclusively by clamping. Preferably The binding has two binding elements and optionally a ski brake, which by a Connecting web are connected together.

The mounting device 10 preferably protrudes beyond the otherwise substantially flat Surface 26 of the ski 2 and is typically in the conventional binding mounting area of the ski. According to the spatial representation in Figure 1, the Mounting device 10 along the length of the ski 2 different cross-sectional shapes and / or dimensions, in order to ensure the most harmonious transition possible from the flat ski surface 26 to form the mounting device and the optimal bending line of the ski at least largely to maintain. The length of the mounting device 10 is from the mounting point from about 250 to 400 mm in each direction, so it has a total length from about 500 to 800 mm. The height of the ski 2 in the region of the mounting device 10 is preferably in the range between about 12 to 25 mm and can along the length of Skis 2 vary. The width of the mounting device 10 is in the range of about 50 to 95%, preferably in the range of about 75 to 90% of the smallest width of the ski body 4. The groove 22nd or 24 preferably has a depth of about 2.0 to 5.0 mm, more preferably about 2.5 to 3.5 mm, and a height or width of about 1.5 to 4, 0 mm, more preferably from about 2, 0 to 3.0 mm.

FIGS. 3 and 4 show two exemplary embodiments of the invention Ski shown in cross-section. According to these illustrations, the ski body 4 in Essentially a tread 28, a Skikern 30 and a cover layer 32, extending from the tread 28 extends around the ski core 30 from one side of the ski 2 to the other. Of the Skikern 30 is essentially made of individual layers glued together and pressed together, typically constructed of organic materials (e.g., wood) with additional deposits 34 and 36 are provided, in which the grooves 22 and 24 are formed. Preferably the ski body 4 further comprises over and / or under reinforcement layers (not shown) the ski core 30, e.g. metal, plastic (e.g., epoxy prepregs). The inserts 34, 36 may extend over part of the height of the ski core, such as this is shown in FIG. 3, or over the entire height of the core 30, as shown in FIG. The inserts 34 and 36 - also referred to as guide parts - are preferably made of a thermosetting plastic, thermoplastic, made of a fiber-reinforced plastic, in particular glass-fiber reinforced plastic, or of a plastic-coated Metallic material is formed to match the free ends 18 and 20 of the commonly used To provide good sliding properties to metal engaging means (e.g., steel) 16; so that the binding elements 12 and 14 can be moved well along the ski 2.

It should also be taken into account that for a sufficient integration of deposits 34 and 36 into the ski body may require pretreatment (e.g., bonding pretreatment). the parts to be connected may be required to have the necessary affinity to the Skibau typically used epoxy resins, or produce Epoxidprepregs.

The deposits or guide parts 34 and 36 may be, for example, prefabricated profile or Be receiving rails that have the grooves 22 and 24 already. When gluing the ski body 4, the rails are co-pressed, so integrated into the ski body.
