Den foreliggende opfindelse angår et af kunststof bestående stakit eller lignende gitterformet element af den art, som er angivet i indledningen til krav 1. De fleste stakitter i et blot nogenlunde billigt prislag er 5 udsat for vejrligets tæring og kræver jævnlig vedlighol-delse, hvis de skal beholde et smukt udseende og en god styrke, herunder i overgangen mellem gitterstavene og skinnedelene. Det er dog allerede foreslået at anvende plastmaterialer til både gitterstavene og skinnedelene, 10 hvorved elementerne nok kan holde til vejrliget, men dels fortsat er udsat for misfarvning og dels er bekostelige i fremstilling og montering, således at de ikke hidtil har vundet nævneværdig udbredelse.The present invention relates to a plastic fence or similar lattice-shaped element of the kind set forth in the preamble of claim 1. Most fences in a fairly reasonably priced layer are subject to weathering and require regular maintenance if they are maintained. must retain a beautiful appearance and good strength, including in the transition between the lattice rods and the rail portions. However, it has already been proposed to use plastic materials for both the lattice rods and the rail portions, 10 whereby the elements can withstand the weather, but are still subject to discoloration and partly costly in manufacture and assembly, so that they have not so far gained significant distribution.

Opfindelsen har til formål at angive et stakitele-15 ment, som er af enkel opbygning og stor holdbarhed.The invention aims to provide a fence element which is of simple construction and high durability.

Dette opnås ifølge opfindelsen ved, at stakitelementet er udført på den måde, der er angivet i den kendetegnende del af krav 1. I et sådant stakitelement vil gitterstavene og skinnedelene fremtræde som integrerede 20 dele af en "monolitisk" konstruktion, dvs. der vil være tale om et som helhed præfabrikeret element, der ikke kræver nogen form for indbyrdes montering af gitterstavene og skinnedelene. Skalparterne er velegnede til udførelse i kunstharpiksmaterialer, der som bekendt kan 25 være vejr- og farvebestandige i højere grad end f.eks. ekstruderede profilstykker af termoplastisk materiale, og ved dobbeltskalkonstruktionen kan opnås betydelig styrke af elementet selv med ret tynde skaller, dvs. elementet kan produceres med lave omkostninger. Desuden 30 kan elementet på arkitektonisk fordelagtig måde være formgivet ved enhver ønsket overgangsform mellem gitterstavene og skinnedelene.This is achieved according to the invention in that the fence element is constructed in the manner defined in the characterizing part of claim 1. In such a fence element, the grating rods and the rail parts will appear as integral parts of a "monolithic" structure, ie. it will be a prefabricated element as a whole that does not require any kind of mounting of the lattice rods and the rail parts. The shell parts are well suited for execution in artificial resin materials which, as you know, can be weather and color resistant to a greater extent than e.g. extruded profile pieces of thermoplastic material, and by the double-shell construction considerable strength of the element can be obtained even with rather thin shells, ie. the item can be produced at low cost. In addition, the element may be designed in an architecturally advantageous manner at any desired transitional form between the grid bars and the rail portions.

Ved stakitelementer, der opadtil er afsluttet med en langsgående gelænderskinne, kan en langsgående sam-35 ling mellem de to skalparter ytre sig som en berøringsmæssigt uheldig, langsgående grat, der i givet fald kanIn the case of fence elements which are closed upwardly with a longitudinal railing rail, a longitudinal joint between the two shell parts may appear as a touchingly unfortunate longitudinal grate, which may

2 kræve en omhyggelig slidbehandling. Dette problem kan imidlertid på enkel måde løses ved den i krav 2 angivne indretning af elementet.2 require careful wear treatment. However, this problem can be easily solved by the arrangement of the element according to claim 2.

Ved det i krav 3 angivne opnås, at de benyttede 5 halvskaller er af identisk form, dvs. at de kan fremstilles ved hjælp af et og samme formningsudstyr.In accordance with claim 3, it is achieved that the 5 half shells used are of identical shape, ie. that they can be manufactured using one and the same forming equipment.

Opfindelsen omfatter tillige den i krav 4 angivne fremgangsmåde til fremstilling af det pågældende stakitelement. Der bibeholdes herved et kraftigt styrkegivende 10 fladeanlæg mellem de samlede skallegemer på en æstetisk fuldt acceptabel måde, idet de sammenbundne pladedele kan strække sig som en enkelt kun let udstående pladeribbe langs midten af gitterstav og skinnedelens sideflader.The invention also encompasses the process of manufacturing the particular fence element as claimed in claim 4. Hereby, a strong reinforcing surface system is maintained between the assembled shell bodies in an aesthetically acceptable manner, the bonded plate parts extending as a single, only slightly protruding plate rib along the center of the grid bar and the side surfaces of the rail portion.

15 Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, på hvilken fig. 1 er et perspektivbillede af en form til fremstilling af et skallegme til brug i et stakitelement ifølge opfindelsen, 20 fig. 2 et perspektivbillede af et sådaant skallege me set fra dettes inderside, fig. 3 et til fig. 1 svarende billede af formen under en senere fase af fremstillingen af et stakitelement, 25 fig. 4 et til fig. 2 svarende billede af det rå fremstillede stakitelement, fig. 5 et detailbillede af et udsnit af dette element i færdiggjort form, og fig. 6 et planbillede af et udsnit af det færdige 30 element.The invention will now be explained in more detail with reference to the drawing, in which: 1 is a perspective view of a mold for making a shell body for use in a fence element according to the invention; FIG. 2 is a perspective view of such a skull toy seen from the inside thereof; FIG. 3 is a view of FIG. 1 is a similar view of the mold during a later phase of the manufacture of a fence element; FIG. 4 is a view of FIG. 2 is a similar view of the raw fabricated fence element; FIG. 5 is a detail view of a section of this element in finished form; and FIG. 6 is a plan view of a section of the finished element.

Den i fig. 1 viste form er betegnet med 2 og opviser en plan overside 4, hvori der er tildannet et par langsgående yderspor 6 hver bestående af en yderste, dyb spordel 8 og en indenfor denne beliggende spordel 10 med 35 mindre dybde. Imellem spordelene 10 er med samme dybde som disse udformet et antal tværgående spor 12, hvorafThe FIG. 1 is indicated by 2 and has a planar top face 4 in which are formed a pair of longitudinal outer grooves 6 each consisting of an outer, deep groove portion 8 and a groove portion 10 of this depth located at a smaller depth. A number of transverse grooves 12 are formed between the groove portions 10 at the same depth as these

3 de yderste er beliggende lidt indenfor enderne af de langsgående spor 6.3 the outermost are located slightly within the ends of the longitudinal grooves 6.

På eller i denne form oplægges en polyestervædet glasfibermåtte, som efter formningen vil få et udseende 5 som vist i fig. 2. Det pågældende skallegeme kan have åbninger i de fladedele, som ligger imellem spordelene 12 i formen jfr. fig. 1, idet der blot findes plane randmaterialedele 18 udstående fra kanterne af de emnedele, 20 og 22, som repræsenterer aftrykkene af hen-10 holdsvis sporene 12 og 10 i formen, 24, af de ydre spor-dele 8 i formen 2; disse aftryk er i fig. 2 vist afsluttet retlinet efter de nedre yderkanter af spordelene 8, men naturligvis kan dette være resultatet af en afskæring af skallegemet, efter at dette er formet også langs 15 ydervæggene af sporene 8.On or in this mold is laid a polyester wetted fiberglass mat which after forming will have an appearance 5 as shown in fig. 2. The shell body in question may have openings in the surface parts which lie between the groove parts 12 in the mold, cf. FIG. 1, there being only planar edge material portions 18 projecting from the edges of the workpiece portions 20 and 22 which represent the prints of the grooves 12 and 10, respectively, in the mold, 24, of the outer groove portions 8 of the mold 2; these images are in fig. 2 shown, the rectilinear is completed along the lower outer edges of the groove portions 8, but of course this may be the result of a cut of the shell body after this is also formed along the outer walls of the grooves 8.

Ved enderne af de ydre sporaftryk 22,24 er disse tildannet med en tværvæg 26 svarende til endevæggene af spordelene 8 og 10 i fig. 1, og udenfor disse dele har emnet 14 videre udragende pladedele 28, som flugter med 20 de nævnte pladedele 18 imellem de tværgående sporaftryk.At the ends of the outer groove prints 22,24, these are formed with a transverse wall 26 corresponding to the end walls of the groove portions 8 and 10 of FIG. 1, and outside of these parts, the blank 14 further has protruding plate portions 28 which align with the said plate portions 18 between the transverse groove prints.

Formen 2 er således tildannet, at emnet 14 vil være symmetrisk omkring den korteste midterakse, eventuelt også om den langsgående midterakse, og efter at et nyt emne er tildannet i formen belægges dette på fladerne 18 25 med et tyndt, polyestervædet fiberlag, hvorefter det tidligere fremstillede emne 14 i omvendt tilstand nedlægges på emnet i formen, således som det er vist i fig.The mold 2 is formed so that the blank 14 will be symmetrical about the shortest central axis, possibly also about the longitudinal central axis, and after a new blank is formed in the mold, it is coated on the surfaces 18 25 with a thin polyester woven fiber layer, after which the former manufactured article 14 in reverse mode is deposited on the article in the mold as shown in FIG.

3. Senere fjernes det således samlede dobbeltemne fra formen, hvorved der fremstår et skallegeme 30, fig. 4, 30 der ved udtagningen fra formen har det udseende, som er vist i højre side af fig. 4, dvs. med uregelmæssigt udstående pladekantdele 18 ved legemets midterplan.3. Later, the double blank thus assembled is removed from the mold, leaving a shell body 30, FIG. 4, 30 which, when removed from the mold, has the appearance shown in the right-hand side of FIG. 4, i.e. with irregularly protruding plate edge portions 18 at the median plane of the body.

Skallegemet 30 underkastes derefter en behandling, ved hvilken pladekantdelene 18 renskæres til dannelse af 35 kort udstående, regelmæssige ribbedele 32, som er rundt-gående i de enkelte felter af skallegemet, således som 4The peel body 30 is then subjected to a treatment in which the plate edge portions 18 are clean cut to form 35 short-standing, regular rib portions 32 which are perpendicular to the individual fields of the peel body, such as 4

det er vist i venstre side af fig. 4. Disse felter er dannet imellem de resulterende lodrette stav- eller rørdele 34 og de øvre og nedre, skinneagtige dele 36.it is shown in the left side of FIG. 4. These fields are formed between the resulting vertical rod or pipe portions 34 and the upper and lower rail-like portions 36.

Ved de frie ender af disse skinnedele 36, se fig. 5, 5 afskærer man fortrinsvis de udragende pladedele 28 (fig.At the free ends of these rail portions 36, see FIG. 5, 5, the protruding plate parts 28 are preferably cut off (FIG.

3) helt, således at der dannes en plan endeafslutning 38, (fig. 5), med hvilken det fremstillede stakitelement kan monteres stødende tæt op til et naboelement, hvilket er antydet i fig. 6.3) completely so as to form a flat end end 38, (Fig. 5), with which the fabricated fence element can be mounted adjacent close to a neighboring element, as indicated in Figs. 6th

10 I den viste udførelse er de vandrette skinnedele 36 åbne heholdsvis opefter og nedefter, selvom de naturligvis udmærket kan tildannes i lukket udførelse. Det er ønskværdigt, at den nedre skinnedel er åben nedefter, navnlig når den øvre skinnedel ikke er helt tæt lukket 15 opefter, en sådan øvre lukning er uhensigtsmæssig, hvis der ønskes en glat, gelænderagtig fremtoning af den øvre skinnedel, hvorfor det i så fald foretrækkes, som vist i fig. 4 og 5, at tildække den åbne øvre skinnedel 36 med et dækselprofil 40, som kan fastgøres til siderne af 20 skinnedelen på egnet måde, f.eks. ved limning.In the embodiment shown, the horizontal rail portions 36 are open up and down, respectively, although they can of course be formed very well in closed design. It is desirable that the lower rail portion is open downward, especially when the upper rail portion is not fully closed upwardly, such an upper closure is inappropriate if a smooth, rail-like appearance of the upper rail portion is desired, so in that case is preferred, as shown in FIG. 4 and 5, to cover the open upper rail portion 36 with a cover profile 40 which can be attached to the sides of the rail portion in a suitable manner, e.g. by gluing.

Det således tilvejebragte stakitelement, der ved opstillingen kan være stolpestøttet på egnet måde, udmærker sig ved at være en særdeles formfast og stærk letvægtskonstruktion, der på vedligeholdelsesfri måde 25 kan fremstå med en smuk overflade med enhver ønsket farve.The fence element thus provided, which in the arrangement may be post-supported in a suitable manner, is distinguished by being a very mold-resistant and strong lightweight construction which can appear in a maintenance-free manner 25 with a beautiful surface of any desired color.

Det vil forstås, at stakitelementet kan formgives på nærmest enhver ønsket måde, f.eks. med mere eller mindre afrundede overgange mellem stakitstavene 34 og 30 skinnedelene 36, hvilket i sig selv kan indebære helt nye æstetiske virkninger, ligesom f.eks. stakitstavene ikke behøver at være retlinede eller at have rektangulært tværsnit. Stakitelementet kan f.eks. opvise flere end to langsgående skinnedele 36, og om ønsket kan sta-35 kitstavene 34 være forlænget opefter, hvis elementet ikke skal fremstå, som det er antydet med punkterede linier ved 42 i fig. 6.It will be understood that the fence element can be designed in almost any desired manner, e.g. with more or less rounded transitions between the fence rods 34 and the rail portions 36, which in itself may involve entirely new aesthetic effects, such as e.g. the fence rods do not need to be rectilinear or to have rectangular cross sections. The fence element may e.g. exhibit more than two longitudinal rail portions 36, and if desired, the base kit rods 34 may be extended upward if the element is not to appear, as indicated by dashed lines at 42 in FIG. 6th
