Definitions
- the invention relates to a ski in shell construction, in which the inner load-bearing structure is covered laterally and upwards by a shell made of preferably unreinforced plastic, which adjoins a flat lower assembly, consisting at least of an outsole and optionally steel edges .
- the enclosed empty space formed thereby is foamed out to form a core after the connection to the lower part of the ski.
- a separate decorative layer applied to the shell is preferably provided (EP-A 0 394 835).
- Shell material is pressed into the mold cavity with the aid of the prefabricated ski core and is brought into the final shape by the shell and finally connected to the lower part of the ski, e.g. is glued (DE-C 38 03 483).
- Another known proposal is that a pliable, thin-walled plastic film is introduced into the mold cavity of an upper mold in such a way that the film conforms to the wall of the mold cavity; the upper mold lined in this way is placed on the lower mold, which receives the load-bearing ski construction with the lower flange, upper flange and core, and the remaining cavity is filled with foam.
- the decor can be applied to the cover film before or after carrying out this process (EP-A 0 498 963).
- the object of the invention is to provide a shell ski which is characterized by low weight with good strength properties and which is also accessible to efficient production.
- one or more hollow bodies with walls made of fiber-reinforced plastic are arranged in the space enclosed by the upper shell formed from a deformed plastic cover sheet and the components of the lower flat assembly.
- the hollow body or bodies fill, if necessary with any additional inlays, the interior space between the shell and the components of the flat lower assembly.
- hollow bodies are intended which extend in the longitudinal direction of the ski, preferably essentially over the entire length of the ski.
- the one or more hollow bodies can preferably be formed from circumferentially closed, synthetic resin-fiber material tubes which are formed by inflation.
- a mold consisting of two mold halves, in the mold cavity of which the ski is shaped, the following method steps being provided according to the invention: a) the components of the lower mold are inserted into the recess of the first mold half Module inserted; b) one or more tubular fibrous fabric impregnated with synthetic resin are provided with inner tubes made of airtight material and positioned in the mold, for example placed on the components of the lower assembly inserted into the first mold half; c) Furthermore, a plastic cover film, optionally provided with a decor and / or an outer protective film, is positioned in the mold, for example placed over the synthetic resin fiber tube (s) (if these were already in place), the side edges of the Cover foil protrudes beyond the side edges of the recess of the first mold half; d) when the second mold half is placed on the first mold half with a mold cavity corresponding to the side and surface contour of the ski body, the protruding edges of the cover film are positioned
- the compressed air overpressure in the hoses is eliminated and the ski is removed from the mold. After demolding, any will still be over the edges of the cover film projecting beyond the side surfaces of the lower component group, if necessary in such a way that the hardened synthetic resin of the hollow body or the hollow body forms a gap-filling web between the lateral lower edge of the shell and the upper side of the lower flat assembly, preferably the steel edge .
- the hoses can be removed from the cavities of the now hardened hollow bodies for reuse.
- Hoses can also remain inside the hollow chambers. If the cover film was provided with a protective film, this protective film is removed after the manufacturing process has ended.
- the plastic cover sheet deformed to form the upper shell must have sufficient pliability, should therefore have a relatively small thickness, for example less than 1.0 mm, preferably about 0.5 mm, and should preferably be made of a plastic material with a modulus of elasticity less than 5000 N / mm 2 , preferably from 1000 N / mm 2 to 3000 N / mm 2 .
- Unreinforced, preferably thermoplastic plastics such as ABS copolymers or polyamide fall into this range.
- a preferably fibrous structure impregnated with synthetic resin is used, the fibrous structure already being able to exist in a “seamless” tubular shape, for example as a tubular braid; otherwise you can also form a flat fibrous fabric, such as fabric or unidirectional layers, into a tube.
- the fibers can be oriented in different directions, for example in the case of a tubular braid at an angle to the longitudinal extension of the Tubes, optionally in connection with coiled fiber strands, which extend in the longitudinal extent of the tubes.
- the synthetic resin with which the fibrous structure is impregnated can be a thermosetting reactive resin, for example polyester resin or epoxy resin.
- Prepreg coils or prepreg tubes in which the matrix material can be thermoplastic as well as thermosetting can also be used for the synthetic resin-fiber material tubes.
- the prepreg is already in a pre-hard state. Even if one starts from several synthetic resin-fiber material tubes, an integral (one-piece) supporting inner hollow body having a corresponding number of hollow chambers can be achieved as a result.
- further reinforcement layers can also be inserted into the mold, for example made of fiber materials impregnated or already bound with synthetic resin and / or of light metal; these additional reinforcement layers are preferably coated with adhesive before insertion into the mold.
- the inserts can serve to reinforce the belt layers and, like the synthetic resin-fiber material tubes, extend essentially over the entire length of the ski or can also be inserts limited in the longitudinal direction of the ski, for example in the binding area to increase the screw pull-out strength.
- the inlays can also be three-dimensional in shape, such that they serve as a damping or stabilizing element and, if necessary, on the ski surface sign off.
- wedge-shaped or gusset-shaped inserts can be arranged above and / or below the partition walls, which reduce the buckling length of the partition walls.
- the device used to carry out the method according to the invention consists, in addition to workstations, for preparing and printing the plastic cover film and for preparing the synthetic resin-fiber tubes with the inner airtight hoses essentially of a two-part form, one half of the form being a recess for receiving the construction - Has parts of the lower assembly of the ski (outsole, steel edges) and the mold cavity of the other mold half is designed according to the three-dimensional side and / or surface contour of the ski. In principle, this corresponds to the known prior art.
- a mold suitable for carrying out the method according to the invention must have a compressed air connection leading to the mold cavity, to which the airtight hoses arranged within the synthetic resin-fiber material tubes can be connected.
- the lateral closing surfaces of the first mold half and the second mold half must be designed in such a way that, when the mold is closed, a gap limited by stops is formed in that area of the closing surfaces which receives the edge zones of the cover film, the height of which is approximately equal to that Thickness of the cover film is. If necessary in connection with the gap-forming stop surfaces on the closing surfaces of the first mold half, protrusions protruding upwards can be formed on the closing surfaces of the first mold half, on which the edges of the cover foil brought into the arched state when the cover foil is placed on the first mold half can support for the temporary preservation of the curvature.
- the outer edge regions of the closing surfaces of the mold halves should lie on top of one another in a sealed manner, it being advantageous if on the outer edge regions separate sealing strips of elastically deformable material, for example the sealing surfaces of the first mold half and / or second mold half can be arranged from elastomeric plastic.
- At least one of the mold halves should be heatable in order to harden the reaction resin.
- To cure the reaction resin it would also be possible to supply heated compressed air into the airtight hoses in the synthetic resin fiber tubes. Cold-curing reactive resin systems that do not require additional heat can also be used.

- the inside of the ski is laterally and upwards from a shell 3 made of non-reinforced plastic, e.g. ABS or polyamide, enclosed.
- the inner load-bearing structure of the ski is formed by a hollow body 4 with walls 5, 6 made of fiber-reinforced thermoplastic or thermosetting plastic, e.g. glass fiber reinforced polyester resin or epoxy resin.
- the inner hollow body 4 fills the interior between the upper shell 3 and the lower assembly 1, 2 such that the outer walls 5 abut the inner walls of the shell 3 or the lower assembly 1, 2.
- the hollow body 4 also has vertical partitions 6 which divide the interior of the hollow body 4 into three air-filled hollow chambers.
- the hollow body 4 extends essentially over the entire length of the ski. In the tip and end area, the hollow body 4 can optionally be replaced by special end components.
- the flat lower component group again consists of the outsole 1 and the steel edges 2; however, an intermediate layer 7 is also present over the length of the ski. act, which can consist of a load-bearing material, for example of fiber-reinforced plastic or metal, or of non-load-bearing material, for example of unreinforced plastic or wood.
- an outer shell 3 made of non-reinforced plastic and inside a hollow body 4 with walls 5, 6 made of fiber-reinforced plastic.
- the hollow body 4 has only one vertical intermediate wall 6, which divides the interior of the hollow body into two air-filled hollow chambers.
- FIGS. 3-5 The method according to the invention for producing a ski according to FIG. 1 is explained with reference to FIGS. 3-5.
- a cover film 8 is made in a flat configuration
- the cover film can be transparent and is then e.g. screen printed, preferably on the inside of the finished ski.
- the film thickness can e.g. 0.2 - 1.0 mm, preferably 0.5 - 0.6 mm.
- the cover film 8 must have a sufficient length and width corresponding to the subsequent deformation.
- the cover film can be a uniform film consisting of a single plastic or consist of areas of different or differently colored plastics which are, for example, integrally connected to one another. In the processing state, however, a cover film assembled in this way is also in one piece.
- the components of the lower assembly of the ski namely the outsole 1 and the steel edges, are inserted into the recess 9 of the first mold half formed here as the lower mold 10 2, inserted.
- These components 1, 2 can already be connected (glued) to one another before being inserted into the recess 9 of the lower mold 10.
- Resin-fiber tubes 11 are then placed on the components 1, 2 of the lower assembly of the ski (for example, made of glass fiber impregnated with polyester resin or epoxy resin, the inner tubes 12 made of airtight material) are provided.
- the cover film 8 is then placed over the synthetic resin-fiber material tubes 11, the side edges of which protrude laterally beyond the depression 9 of the lower mold and are supported on projections 13 of the lower mold.
- the second mold half here the upper mold 14 is placed on the lower mold 10 and has a mold cavity corresponding to the side and surface contour of the ski body (FIG. 4).
- Both the closing surfaces 15 of the lower mold 10 and the closing surfaces 16 of the upper mold 14 have sealing strips 17 and 18 on the outermost edge, which are made of an elastically yielding material, e.g. consist of an elastomeric plastic.
- lateral gaps which open into the mold cavity are further formed by appropriate design of the closing surfaces 15, 16.
- the lateral edge zones of the cover film 8 lie in this column.
- the gap thickness is dimensioned such that the edge zones of the cover film 8 just fill the gap, but are not immovably clamped in the gap.
- the hoses 12 are connected, for example, on one of the longitudinal ends of the mold cavity to a compressed air supply formed in one of the mold halves 10, 14. closed.
- the tubes 12 are inflated, they expand and the synthetic resin-fiber material tubes 11 are also expanded.
- the edge zones of the cover film 8 located between the upper mold 14 and the lower mold 10 are at least partially pulled out of the edge gap, and the cover film 8 lies on the cover film without stretching or stretching and without any distortion 8 attached decorations to the inner mold wall of the upper mold 14.
- the shape and position of the synthetic resin-fibrous tubes 11 are also shown in FIG.
- the synthetic resin of the synthetic resin-fibrous tubes being able to escape from the tubes due to the pressure exerted by the inflated hoses 12 and complete contact with the inner wall of the cover film 8 and the components 1, 2 of the lower assembly of the ski and also between the individual synthetic resin-fiber tubes 11. Due to the synthetic resin of the synthetic fiber-fiber tubes 11, the adhesion with the cover film 8 is also reduced
- the synthetic resin emerging from the synthetic resin-fibrous tubes 11 also effects the adhesive connection (adhesive connection) between the steel edges 2 and the preferably flange-like outwardly bent edges of the cover film 8. If appropriate, the synthetic resin can also penetrate between the legs and the outsole 1 and so also glue these two components together, if the steel edges have not already been glued to the outsole 1 before being inserted into the lower mold. To a certain extent, the three synthetic resin-fiber tubes 11 grow together into a single integral structure consisting of three hollow chambers.
- the heat supply for curing the synthetic resin takes place while maintaining the compressed air pressure in the hoses 12. The supply of heat expediently begins at the same time as the expansion phase of the hoses 12, but it can also take place at different times.
- the mold After curing, the mold is opened. Any protruding edges of the cover film 8 are cut off.
- the cover sheet 8 is thus identical to the shell 3 shown in FIG. 1 and the synthetic resin-fiber material tubes 11 now form the integral hollow body 4 shown in FIG. 1 with the walls 5, 6 made of fiber-reinforced plastic and three hollow chambers.
- the hoses 12 can be removed from the chambers of the hollow body, through corresponding openings in the area of the ski tip or the rear of the ski, these openings subsequently being e.g. can be closed by a tip protector or end protector.
- Fig. 6 For the coordination of the skiing properties, it is expedient to specify the ability of the ski to deflect and to make it variable during manufacture. This may, as shown in Fig. 6 can be seen, for example, take place in that the free buckling length l ⁇ of the intermediate walls 6 by Ver ⁇ application is changed from a wedge or zwickeiförmigen elements 19.
- the wedge-shaped or gusset-shaped elements 19 can consist of prefabricated plastic profiles, for example of fiber-reinforced plastic in the form of a profile, or also of wood in a corresponding strip shape.
- the ski cross section according to FIG. 7 relates to an exemplary embodiment of a ski according to the invention, again with a lower flat assembly consisting of Outsole 1 and steel edges 2 as well as an outer shell 3 made of non-reinforced plastic and an inner three-chamber hollow body 4 with walls 5, 6 made of fiber-reinforced plastic, above and below the vertical intermediate walls 6 are wedge-shaped or gusset-shaped elements or designs 19 for reduction the free buckling length of the partition walls.
- These elements or designs can be formed by prefabricated inlays or by controlling the pressure when the synthetic resin-fiber material tubes forming the hollow body 4 are inflated, synthetic resin emerging from the synthetic resin-fiber material composite forming the wedge-shaped or twisted elements 19.
- a reinforcing insert 20 made of fiber-reinforced plastic or metal is provided between the outside of the hollow body 4 and the inside of the shell 3 to reinforce the upper chord or to reinforce the binding attachment area.
- this reinforcement insert 20 extends only over the width of the upper side of the three-chamber hollow body 4 and not also into the region of the side walls of the ski.
- the reinforcement insert 20 can extend over the entire length of the ski or only over part of the length, e.g. extend over the binding attachment area.
- the reinforcement insert 20 is preferably connected to the still flat cover film, for example before the cover film for the shell 3 is inserted into the mold, e.g. glued.
- the lower side edges of the shell 3 are bent out like a flange. Their underside lies at a short distance, for example of about 0.5 mm, above the top of the steel edges 2 (or generally above the top of the bottom flat assembly).
- the still flowable synthetic resin of the synthetic resin-glass fiber tubes of the hollow body 4 penetrates into the gap formed in this way, and after hardening forms a web 21 made of hardened synthetic resin, which connects the side edges particularly well the shell 3 with the steel edges 2 guaranteed.
- the basic structure of the ski again consists of the flat lower assembly (outsole 1, steel edges 2), the outer shell 3 and the inner load-bearing hollow body 4, which is again a three-chamber hollow body.
- Strip-shaped reinforcing inserts 22 made of synthetic resin-bonded carbon fibers or metal are arranged between the top of the hollow body 4 and the shell 3 made of non-reinforced plastic.
- Carbon fiber inserts 23 also contain the walls of the two lateral hollow chambers of the hollow body 4, which otherwise consists of a synthetic resin-glass fiber composite.
- the thread-like carbon fiber inserts 23 can be braided into the glass fiber reinforcement of the synthetic resin-fiber material tubes, which preferably consists of a tubular braid, from which the hollow body 4 is formed.
- the lateral chambers of the hollow body 4 are reinforced by the carbon fiber inserts for better support of the edge region of the ski.
- the side synthetic resin fiber tubes (compared to the middle synthetic resin fiber tube) can also be made with larger wall thicknesses and / or with an increased fiber content, e.g. Glass fiber content, equip.
- the hollow body 4 extends essentially over the entire length of the ski. This preferably also applies to the other leadership examples. However, if, as in FIG. 2, there is an additional supporting lower chord layer 7 and, as in FIG. 7, there is an additional supporting upper chord layer 19, it would be possible to use hollow bodies which are divided in the longitudinal direction of the ski, for example in such a way that in the front Part and in the rear part of the ski there is a separate hollow body and in the middle area (binding attachment area) there is a solid core.
- a trapezoidal ski cross-section and a correspondingly shaped mold cavity were chosen in particular for reasons of simplicity of illustration.
- the invention also allows others, e.g. cross-sectional shapes arched upward, and cross-sectional shape that changes almost arbitrarily in the longitudinal direction of the ski.
- the method and construction according to the invention are particularly suitable for alpine skis, but can also be used on cross-country skis, snowboards and other skis or ski-like sports equipment.
