Definitions

  • the invention relates to a method for producing a ski, preferably alpine skis, with a lower assembly consisting essentially of steel edges, outsole and lower flange, an upper assembly consisting essentially of an upper flange and core, and with a cover film which the upper Assembly of the ski body encased in one piece.
  • Skis of this design are increasingly being manufactured and are referred to as "shell skis" or “cap skis".
  • the shaping is usually carried out in the mold cavity of a mold consisting of the lower mold and the upper mold.
  • a shell-shaped upper part made of optionally fiber-reinforced plastic with flange-like side edges is produced in a specially provided shape, either together with the ski core or merely as a shell, the pre-manufactured ski upper part being connected to the likewise pre-manufactured lower part of the ski.
  • the enclosed empty space formed in this way is foamed after connection to the lower part of the ski to form a ski core.
  • the skirts are preferably provided with a separate decorative layer applied to the shell (EP-A 0 394 835).
  • Yet another known method provides that the multilayer shell material is placed in a flat configuration on the mold cavity of a lower mold, the edge regions of the flat shell material initially protruding laterally beyond the mold cavity, whereupon the shell material is pressed into and through the mold cavity with the aid of the prefabricated ski core the shell is brought into its final shape and finally connected to the lower part of the ski, for example 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 then placed on the lower mold, which receives the load-bearing ski construction, 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). It is also known to insert the components of a lower assembly of the ski (outsole, lower flange, steel edges) into the recess of the lower mold, and to put on the cover material consisting of a decorative film, a reinforcing layer and a sealing layer in a pre-shaped, arched shape, the after closing the Form the multi-layer casing material and layers of the lower assembly come to lie in the marginal gap between the upper mold and lower mold and are pulled out of this marginal gap when injecting the foam or foam-forming components (EP-A 0 430 824, FR-A 2 678 543).
  • the object of the invention is to improve such a shell ski production and to simplify it compared to the known embodiments of such methods.
  • the method according to the invention is also carried out in a known manner using a mold consisting of the lower mold and the upper mold and consists in that the plastic cover film, optionally provided with a decor and / or an outer protective film, has a planar configuration on one of its sides with at least one reinforcing layer made of strength load-bearing material is connected to a composite shell material, whereupon the cover film with the reinforcement layer facing down is placed on the lower mold, in the recess of which the components of the lower assembly of the ski (outsole, lower belt, steel edges) are inserted, the side edges the cover film protrude the side edges of the recess of the lower mold, whereupon the upper mold with a mold cavity corresponding to the side and surface contour of the ski body is placed on the lower mold and the protruding edges of the composite shell material in an edge gap z between upper mold and lower mold are positioned without being pinched, whereupon foam, possibly in the form of foam-forming components, is finally injected between the reinforcing layer and the lower
  • a single or multi-layer reinforcement layer is connected to the cover film, the width of which is smaller than that of the cover film, so that the lateral edges of the composite shell material thus formed are formed only by the cover film, which is optionally provided with a protective film, for which reason alone Cover film, possibly including protective film, is positioned in the edge gap between the upper mold and lower mold to fill the gap without being pinched. This creates favorable conditions for the gap seal towards the mold cavity.
  • the plastic cover sheet 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 be made of a plastic material with a modulus of elasticity below 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.
  • the protective film optionally arranged on the outside of the cover film can e.g. be an easily peelable self-adhesive polyethylene film with a thickness of about 0.1 mm. After completion of the ski, the protective film is removed from the cover film, which is now shaped like a shell.
  • a fiber-reinforced plastic As a strength-bearing material for the reinforcement layer to be connected to the cover film in a still flat configuration and acting as a top chord, e.g. a fiber-reinforced plastic may be considered, whereby the plastic may already have hardened when the layer is connected to the cover film (e.g. by gluing). Instead, however, the layer of fiber-reinforced plastic can first be connected to the cover film as a prepreg, with the curing of the foam injected when the mold is closed also resulting in the curing of the prepreg. The advantage of using prepregs is that they are pliable.
  • the lower chord layer of the lower assembly can also be inserted into the lower mold as a prepreg.
  • the reinforcing layer connected to the cover film and / or the lower chord layer can in principle also be a metal layer, preferably made of an aluminum alloy, or a double or multiple layer made of metal and / or fiber-reinforced plastic.
  • the cover film connected to the reinforcement layer is either at least approximately flat or (without special preforming) placed on the still open bottom mold so that the edges of the film are supported on projections on the lateral closing surfaces of the bottom mold, the distance between the projection (or the projections) of the left closing surface and the projection (or the projections ) the right closing surface is smaller than the width of the cover film, so that the cover film is forced to bulge.
  • a certain cavity is formed between the lower assembly of the ski inserted into the lower mold and the cover film connected to the reinforcing layer, which facilitates the injection of the foam.
  • the injected foam can be, for example, a polyurethane-based foam and, when cured, has a density of preferably 0.3 to 0.7 g / cm 3 .
  • An integral rigid foam is preferably used, which forms densified edge zones during curing. These compressed edge zones have a density of approximately 1 g / cm 3 and more, the density being higher in those edge zone regions which are closer to the heated mold walls of the production mold.
  • the device used to carry out the method according to the invention essentially consists of a two-part heatable mold, the lower mold having a recess for receiving the components of the lower assembly of the ski (outsole, Lower flange, steel edges) and the mold cavity of the upper shape 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 further development according to the invention is that the lateral closing surfaces of the lower mold and upper mold are designed so that when the mold is closed, a gap limited by stops forms in that area of the closing surfaces which receives the edge zones of the cover film, the height of which is approximately equal to the thickness of the Shell composite material, preferably only the cover film (optionally including the protective film).
  • protrusions projecting upward on the closing surfaces of the lower mold can be formed, on which the edges of the curved covering film can be supported when the cover film is placed on the lower mold for the purpose of temporarily maintaining the curvature .
  • the outer edge regions of the mold mold halves when the mold is closed should lie sealingly on one another, which is advantageous , if on the outer edge areas of the closing surfaces of the lower mold and / or upper mold separate sealing strips made of elastically deformable material, for example are arranged from elastomeric plastic.
  • the manufacturing method according to the invention enables a ski construction which is characterized by a minimum of functional components, namely with a lower assembly, preferably consisting of an outsole, lower flange and, if necessary, steel edges, and also an upper assembly, preferably consisting of an upper flange and core, and a cover sheet, the plastic cover sheet optionally provided with a decor, the components lying above the lower assembly, preferably in the unstretched state, being shell-shaped and at least one with the inside carries the reinforcing layer connected to the cover film, and an injected foam core is formed between the cover film or the reinforcement layer and the lower assembly.
  • the cured foam has a gap between the lateral lower edge of the cover film and the reinforcement layer Shell composite material, preferably the bottom edge of the cover sheet and the top of the lower assembly, preferably the top of the steel edge, fills web.
  • the foam core consists of integral rigid foam with compressed edge zones, then the foam present in the gap between the lateral lower edge of the shell composite material and the lateral peripheral region of the upper side of the lower assembly is in the compressed state. This is advantageous because the foam material that has penetrated into the gap mentioned is exposed on the outside and is therefore exposed to external influences and also to a possible grinding process of the side edges of the ski.
  • the width of the reinforcement layer is expediently substantially the same or somewhat smaller than the width of the top of the ski, so that when the reinforcement layer is applied centrally to the cover film, the reinforcement layer extends only over the width of the top of the ski and does not also protrude into the area of the side cheeks, the latter also being possible as well as an off-center (asymmetrical) arrangement of the reinforcement layer on the cover film.
  • Fig. 1 shows in cross section the cover sheet with reinforcing layer in a flat configuration.
  • 2 to 4 show in cross section the manufacturing mold with the inserted ski components in different stages of the process.
  • 5 shows an embodiment variant in one 2 corresponding stage of the process.
  • 6 and 7 show a further embodiment variant, the production mold with inserted ski components being shown in FIG. 6 and the finished ski being shown in cross section in FIG. 7.
  • a cover film 1 made of plastic which will usually be provided with a decoration, is first connected on one side to (at least) one reinforcement layer 2 in a flat configuration.
  • the cover sheet 1 can e.g. made of ABS or polyamide.
  • 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 1 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 integrally bonded to one another. In the processing state, however, a cover film assembled in this way is also in one piece.
  • the reinforcement layer 2 to be connected to the cover film 1 can consist, for example, of fiber-reinforced plastic, it being possible for the plastic to be already cured when the reinforcement layer 2 is connected (glued) to the cover film 1. In principle, however, it is also possible to connect a prepreg to the cover film 1 as a reinforcing layer.
  • the width of the reinforcement layer 2 is essential in the case shown less than the width of the cover sheet 1 and arranged centrally on the cover sheet 1.
  • the cover sheet 1 with the reinforcing layer 2 is then, as can be seen from FIG. 2, placed on the lower mold 3, in the case shown that the edges of the cover sheet 1 are supported on projections 4 on the lateral closing surfaces 5 of the lower mold 3 and thereby force the cover sheet 1 together with the reinforcement layer 2 into an arched shape.
  • the components of the lower assembly of the ski namely the outsole 7 (e.g. made of polyethylene), the lower flange 8 (e.g. made of fiber-reinforced plastic or metal) and the steel edges 9 have been inserted.
  • the components of the lower assembly 7, 8, 9 can already be connected (glued) to one another before being inserted into the recess 6 of the lower mold 3.
  • the upper mold 10 is also shown in FIG. 2, but the two mold halves 3, 10 are not yet closed.
  • the upper mold 10 has in the region of its lateral closing surfaces 11 recesses 12 which serve to receive the projections 4 of the lower mold 3.
  • Both the closing surfaces 5 of the lower mold 3 and the closing surfaces 11 of the upper mold 10 have sealing strips 13 and 14 on the outermost edge, which are made of an elastically flexible material, e.g. made of an elastomeric plastic.
  • the lateral edge zones of the cover film 1 come within the projections 4 in a gap formed there between the closing surfaces 5 and 11 of the lower mold 3 and the upper mold 10 to lie.
  • the height of the gap is determined by stops.
  • the gap thickness is to be dimensioned such that the edge zones of the cover film 1 just fill the gap, but are not immovably clamped in the gap. In this state, the cover film 1 with the reinforcement layer 2 is still relatively limp in the mold cavity.
  • the foam can consist, for example, of polyurethane, in which case the components to be injected consist of polyol, isocyanate and a blowing agent.
  • the injection of the foam forces the cover film 1 together with the reinforcement layer 2 against the wall of the mold cavity of the upper mold 10, the edge zones of the cover film 1 located in the edge gap between the upper mold 10 and the lower mold 3 being at least partially pulled out of the edge gap.
  • the cover film 1 can lie against the inner mold wall of the upper mold 10 without stretching (stretching) and without distortion of the decoration which may be applied to the cover film 1.
  • the injected foam forms the core 15 of the ski, but the polymeric material of the foam also serves as an "adhesive" for connecting the individual layers, for example also the components 7, 8, 9 of the lower assembly to one another, if these have not already been glued together .
  • the heat generated during the reaction of the components of the injected foam and the pressure exerted by the expanding foam also creates, if necessary, the curing conditions for the plastic of the reinforcement layer 2, if the reinforcement layer was originally a prepreg (i.e. with not yet fully cured plastic) was connected to the cover film 1.
  • the closing surfaces 5 of the lower mold 3 have no designs corresponding to the projections 4 of FIG. 2.
  • the recesses 12 present in FIG. 2 are also missing in the closing surfaces 11 of the upper mold. 5, however, the closing surfaces 4, 11 are designed such that when the shape is then closed, a gap is formed in which the edge zones of the cover film 1 are received but not clamped. 5, the cover film 1 with the reinforcing layer 2 is inserted into the lower mold 3 essentially in a planar form.
  • the structure of the lower assembly of the ski in FIG. 5 also differs from FIGS. 2 to 4.
  • the lower assembly consist of the outsole 7, the steel edges 9, a lower flange 8 and an intermediate layer 15.
  • the lower flange 8 e.g. made of metal, does not lie between the edge legs, but on it.
  • the intermediate layer can consist of a material with a high strength or merely of wood or unreinforced plastic.
  • the ski produced according to the invention essentially has a trapezoidal cross section.
  • the width of the reinforcement layer 2 was chosen in the case shown because this reinforcing layer forming the upper flange of the ski is located exclusively in the area of the upper side of the ski and does not also protrude into the side cheek areas of the ski.
  • only the cover film 1 is brought into the form of a shell and not also the reinforcement layer 2.
  • the reinforcement layer 2 has the same width in the still flat configuration as that Cover film 1, so that when the mold is closed (corresponding to FIG.
  • the gap between the closing surfaces 5, 11 must be larger than in the embodiment shown in the drawings, corresponding to the thickness of the composite of cover sheet 1 and reinforcing layer 2.
  • the ski produced according to FIGS. 1 to 4 or 5 has the structural features of that ski construction which, in addition to the production method and the device for producing a ski, is also the subject of the present invention.
  • the invention is not necessarily limited to the manufacturing method according to the invention, although this method and the ski construction according to the invention shown are in a mutually beneficial relationship.
  • FIG. 6 shows the upper mold 3 and the lower mold 10 together with inserted ski components, again in a stage corresponding to FIG. 2.
  • the closing surfaces 4, 11 are designed in such a way that, when the shape is closed, a gap 4 is formed on both sides between the closing surfaces 4 and 11, in which the edge zones of the cover foils 1 on both sides are received but not clamped.
  • the cover film 1 with the reinforcement layer 2 is placed in a planar form in the lower mold 3 or is placed on the components of the lower assembly of the ski inserted in the recess 6 of the lower mold 3.
  • the components of the lower assembly of the ski again consist of the outsole 7, a lower flange 8 and the steel edges 9.
  • Shell composite material creates a ski, as shown in Fig. 7 in cross section.
  • the upper cover sheet 1 is shaped into a shell and has the reinforcing layer 2 on its inner upper side.
  • the injected foam forms the core 15 of the ski, the foam also in any spaces 16 of the lower assembly 7, 8, 9 of the ski and in the lateral column 17 penetrates between the lateral lower edge of the cover sheet 1 and the upper side of the steel edges 9. This gap is shown exaggerated in FIG. 7 and in practice only has to have a height of approximately 0.5 mm.
  • the foam material penetrated into the column 17 forms a gap-filling web there, which connects the lower side edges of the shell or the cover film 1 to the steel edges 9.
  • a compacted structure also occurs in the gaps 17, ie in each case a web made of compressed foam.
  • the inner walls of the upper mold 10 are arranged and designed such that the shell formed by the cover film 1 forms flange-like bent out side edges in the finished ski. This measure also ensures a good connection between the lower side edges of the shell or the cover sheet 1 and the steel edges 9 in connection with the foam material penetrated into the column 17.
  • a trapezoidal ski cross-section and a correspondingly shaped mold cavity were chosen in particular for reasons of simplicity of illustration.
  • the method according to the invention also leaves others, for example less cross-sectional shapes curved at the top, and cross-sectional shape changing 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 be used on cross-country skis or other types of skis or ski-like devices (e.g. "snowboards").
