Representations similar to Figure 3 in other possible embodiments.

The generally designated 1 in Figures 1 - 3 ski has - apart from the features described below - the usual structure, d. H. consisting of a lower tread component 3 with the two steel edges 4 and with the running surface or underside of the ski body 2 forming tread 5, from the core 6 of a suitable for snowboard skis or skis core material (eg., Plastic foam and / or Wood), from the top of the ski body 2 and also the side surfaces of this ski body forming shell 7 and an upper and a lower belt-like support layer 8 and 9, which are suitable for such a support layers or straps material, eg. As metal (eg Titanal) and / or fiber-reinforced plastic and extends over the entire length of the ski body.

The ski 1 is designed as a so-called 3D ski, ie the ski body 2 is provided on its upper side formed by the shell 7 with two bead-like projections 10 which extend over a greater part of the length of the ski body, in particular also over the middle Area or binding region of the ski body 2, are attached to the (binding area), the binding or the elements of the bond. The projections 10, which extend in each case along a longitudinal side of the ski body 2, respectively run out in the area of the front and in the region of the rear end of the ski body, ie form terminating ends 10. 1, as shown in FIG is. Between the two projections 10, the ski body 2 on its upper side a trough-shaped depression 11.

In the region of each projection 10, a channel 12 is formed in the core 6 and below the shell 7, which extends as well as the associated projection 10 along the respective longitudinal side of the ski body 2. In the illustrated embodiment, the channels 12 are each open at both ends, in each case at the end or at the outlet 10.1 of the relevant projection 10. Each channel 12 is formed by the interior of a plastic pipe profile 13, which is embedded in the core 6, and although, for example by foaming, for example, with a plastic foam (for example PUR foam) which at least partially forms the core 6 or by incorporation into the core 6 with a synthetic resin used in the production of the ski body 2.

The tube profile 13 is guided in this embodiment at the respective end or outlet 10.1 of the associated projection 10 with the respective end 13.1 through the shell 7 to the outside, so that the there from the shell 7 projecting end 13.1 of the pipe profile, the channel opening 12.1 of the channel 12 forms.

In the channel 12, a trim rod 14 is interchangeably accommodated, whose outer diameter is equal to or smaller than the inner diameter of the channel 12, so that this trim rod 14 can move axially relative to the pipe profile 13 with a certain play. The trim rod 14 is in the illustrated embodiment of a fiber reinforced plastic, for example, glass fiber reinforced plastic or carbon fiber reinforced plastic and is thus designed so that it is elastically deformable by bending. The length of the trim rod 14 is chosen so that it protrudes after insertion into the channel 12 with its ends 14.1 from the channel openings 12.1, as shown in Figure 3 for an end 14.1. With each end 14.1, the trim rod 14 is supported on a bearing or support element 15, which is attached to the top of the ski body 2 of the respective channel opening 12.1 opposite in a suitable manner. At least the support element 15 for the one end 14.1 of each trim rod 14 is provided on the ski body 2 so that, for example, after removal or pivoting away this Supporting element 15 is an insertion or removal of the trim rods 14 in or out of the channel 12 is possible.

With the trim bars 14 u.a. the bending stiffness of the ski body 2 during flexing (flexing) influences, d. H. e.g. be adapted to the wishes and requirements of each user, by using trim bars 14 with different flexural stiffness, which can be achieved for example by appropriate choice of material and / or by a corresponding cross section for the trim bars 14. In order to compensate for the differences in length occurring due to the different bending radius in the flex ski body 2, the bearing or support surfaces formed by the support elements 15 for the ends 14.1 are elastic or resilient, d. H. In the illustrated embodiment, these contact surfaces are formed by an insert 16 made of a permanently elastic plastic material. By appropriate choice of material at the same time a damping is achieved. A further damping effect can be achieved in that the respective trim rod is covered with an elastic, damping material.

The shell 7 consists of a single-layer, but preferably of a multilayer Kunststofffllachmaterial, namely in multi-layered training from an outer, the outer surface of the ski body 2 forming plastic layer (eg surface or decorative film) and an inner supporting layer such as a fiber-reinforced plastic material. As FIG. 2 shows, the shell 7 is in the form of a 3D shell with two sections 7.1 forming the sides of the shell 7 and of the gliding board body 2, with two sections 7.2 forming the later projections 10 on the inside of the shell, and with a central depression 11 of the sliding board body 2bildenden section 7.3 prefabricated. The shell 7 is furthermore part of a shell component 7a, together with the upper belt 8 provided on the inside of the shell 7 on the section 7.3. A special feature of the invention is that the shell component 7a is prefabricated with the tubular profiles 13, ie in each case one Tube profile 13 is received in the trough-like section 7.2, there fastened in a suitable manner and with its ends 13.1 at the ends of the respective groove-like portion 7.2 led out through openings of the shell 7. The pipe sections 13 are held, for example by gluing with a suitable plastic material on the inside of the shell 7.

In the illustrated embodiment, the support elements 15 are prepared in each case on the shell 7 and on the shell element 7a and are passed with an anchoring portion 15.1 through the shell 7 and project with this section on the inside of the shell 7. With the anchoring sections 15.1, the supporting elements 15 are anchored in the core 6 by foaming or in some other way, for example by gluing with synthetic resin.

The shell component 7a prepared with the tube profiles 13 and the upper support element or belt 8 is then introduced together with the other components forming the ski body 2 into the device or mold used for the production of the ski body 2. In order to prevent penetration of the ski body 2 in particular penetration of plastic or synthetic resin into the channels 12 formed by the pipe sections 13, the pipe sections 13 are closed at both ends, in such a way that they are opened with a suitable tool or by simply piercing can be. The corresponding closure is formed for example by a membrane or a releasable sealing plug.

It was assumed above that the trim rods 14 are supported at both ends on a support element 15. In principle, it is also possible to clamp the trim rod 14 only at one end to a holding element or bearing element fastened to the ski body 2.

Above, it was further assumed that the trim bars 14 are led out of the channel 12 at both ends. Other designs are possible. For example, there is the possibility that each channel 12 or each tube profile 13 is closed at one end. This closed, preferably not led out by the shell 7 end of the relevant pipe section 13 then forms For example, a support bearing for an end 14.1 of the respective trim rod 14, or the clamped at its other end trim rod 14 is added spaced in the channel 12 from the closed end.

In the figure 4 is shown in a simplified partial view as another possible embodiment of the invention, a ski 1 a, in which the channels formed by the pipe sections 13 12 are closed at one end in the manner described above and formed with a closure piece 17 or are provided. The e.g. End pieces 17 produced as a molded part or injection molded part from plastic part are adapted to the inner shape of the channel-like region 7.2 at the outlet 10.1 of the projections 10 and held in a suitable manner, for example by gluing to the inner surface of the shell 7 closed at least in this area.

FIG. 5 shows, as a partial representation of another possible embodiment, a ski 1b, in which the tube profiles 13 are formed or provided at least at one end with a closure piece 18. The end pieces 18, which in turn are, for example, molded parts or injection molded plastic, form with their openings 18.1 in this embodiment, the channel openings 12 and are attached to the inner surface of the shell 7 at the section 7.2, for example by gluing or welding, in the region of the outlet 10.1. The respective end piece 18 is in particular also fastened such that the respective opening 18.1 forming the channel opening 12.1 of each end piece 18 is sealed by the shell 7 and thus foreign material, in particular also plastic, can not penetrate into the channel 12 during production of the ski 1b. Only after the production of the ski 1b, the shell 7 is opened in the region of the channel opening 12.1, for example with a suitable tool and / or in that the shell 7 is provided there with an easily removable area, for. B. by a perforation and / or by a reduced material thickness of the shell 7, etc. After opening the respective channel 12 can then be inserted into this through the channel opening 12.1 of the trim rod 14. If, for example, no trim rod is required, then the shell 7 remains closed in the region of the end pieces 18.

The invention has been described above in various embodiments. It is understood that numerous changes are possible without thereby departing from the inventive idea underlying the invention. Thus, for example, the trim bars 14 may also be designed with respect to their mechanical properties different from the properties described above, for example such that these trim bars over their entire length or on a part of their length from a deformable upon deflection of the respective ski, damping material, e.g. consist of soft elastic material.

Furthermore, it is possible to use the used end caps, for example, the end piece 18 so that this end piece also forms the support element or bearing element for the respective trim rod.

Furthermore, it is also possible that each trim rod consists of a bundle of individual rods with the same or different mechanical properties. However, all embodiments have in common that for the production of the ski, a shell component 7a is used, on the shell 7 already at least one channel is prepared for receiving at least one trim rod, so that thereby a rational production of the respective ski or Schneegleitbrettes is guaranteed.
