Predmet izumaThe subject of the invention

Predmet izuma je eksterni podložni sistem za uravnavanje višine smučine smučarske skakalnice, oziroma natančneje eksterni podložni sistem za enostavno uravnavanje položaja smučine na zaletišču smučarske skakalnice glede na daljšo os smučine in določeno ravnino, v horizontalni in vertikalni smeri. Sistem temelji na segmentni izvedbi, ki omogoča nastavitev oziroma regulacijo segmentov smučine vzdolž zaletišča glede na njihovo razdaljo od nosilne konstrukcije, ki je v naprej določena.The subject of the invention is an external washer system for adjusting the ski jump height, or more specifically an external washer system for easily adjusting the position of the ski at the start of the ski jump in relation to the longer axis of the ski and a certain plane, in the horizontal and vertical directions. The system is based on a segmental design that enables the adjustment or regulation of the ski segments along the runway depending on their distance from the load-bearing structure, which is defined in advance.

Tehnični problemA technical problem

Tehnični problem, ki ga rešuje izum je takšen sistem oziroma takšna segmentna konstrukcija smučine, ki bo omogočala nastavitev višine segmentov smučine in njenega položaja v ravnini po celotni ali le delni dolžini zaletišča skakalnice, in to znotraj možne oziroma dovoljene razdalje med nosilno konstrukcijo zaletišča in smučino. Segmentno konstrukcijo smučine bo tvorilo optimalno število segmentov in minimalno število njihovih sestavnih delov, zato bo njena izdelava enostavna, enostavna in hitra pa bo tudi njena vgradnja oziroma montaža na nosilno konstrukcijo zaletišča, kar posledično omogoča enostavno rokovanje v smislu načina njenega uravnavanja in regulacije.A technical problem solved by the invention is such a system or such a segmented ski structure that will allow the height of the ski segments and its position to be adjusted in the plane along the entire or only partial length of the ski jump slope, within the possible or allowed distance between the supporting structure of the ski slope and the ski . The segmental ski construction will form the optimum number of segments and the minimum number of their components. Therefore, its construction will be simple, simple and fast, as will its installation or mounting on the supporting structure of the runway, which consequently enables easy handling in terms of its regulation and regulation.

Stanje tehnikeThe state of the art

Po patentnem dokumentu EP 2 838 626 B1 je znan sistem zaletne steze za naprave za smučarske skoke/smučarske skakalnice, ki služi kot podložni sistem za zaletno smučino. Sestoji se iz vzdolžnih profilnih elementov nameščenih na prečne profilne elemente, ki jih je mogoče s pomočjo distančnih elementov nastavljati po višini. Kanala smučine sta pritrjena na štiri vzdolžne profile, ki ležijo na prečnih elementih. Slabost rešitve tega sistema je zlasti v tem, da je zapletene izvedbe in se sestoji iz velikega števila sestavnih delov, kar ima za posledico zapleteno in drago izdelavo ter dolgotrajno ter zapleteno montažo na nosilno konstrukcijo zaletišča. Temu ustrezna je tudi večja zahtevnost postopka nastavitve oziroma regulacije segmentnih elementov smučine.According to patent document EP 2 838 626 B1, a runway system for ski jumping / ski jumping devices is known, which serves as a backing system for runway skiing. It consists of longitudinal profile elements mounted on transverse profile elements, which can be adjusted by height using spacer elements. The ski ducts are fixed to four longitudinal profiles that rest on the transverse members. The disadvantage of this system is that it is complex in design and consists of a large number of components, which results in complex and expensive construction and long and complicated mounting on the supporting structure of the launch site. This is also due to the greater complexity of the process of adjusting or regulating the segmental elements of the ski.

Na podlagi predhodno opisane znane rešitve ostaja nerešen problem enostavne izvedbe sistema za uravnavanje višine in regulacijo smučine v odnosu na nosilno konstrukcijo zaletišča skakalnice, ki bo omogočal enostavno nastavitev oziroma regulacijo višine smučine vzdolž zaletišče skakalnice in, ki bo nadalje omogočal enostavnejšo in cenejšo izdelavo ter hitro in enostavno montažo sestavnih segmentov.Based on the previously described known solution, the problem remains of the simple implementation of the system for height regulation and ski regulation in relation to the supporting structure of the ski slope, which will allow for easy adjustment or regulation of the ski height along the ski slope, which will further enable easier and cheaper construction and fast and easy assembly of component segments.

Opis izumaDescription of the invention

Rešitev predhodno opisanega tehničnega problema je zasnovana na inovativni konstrukciji smučine smučarske skakalnice z eksternim podložnim sistemom za uravnavanje višine smučine po prijavljenem izumu, ki jo je mogoče uporabiti oziroma vgraditi na leseno, betonsko, železno ali kombinirano nosilno konstrukcijo zaletišča skakalnice.The solution to the technical problem described above is based on an innovative ski jump design with an external ski pitch adjustment system according to the present invention, which can be used or installed on a wooden, concrete, iron or combined load-bearing structure of the ski jump start.

Sestavni segmenti smučine z drsnima kanaloma in eksternim sistemom za njihovo uravnavanje so izdelani in predhodno večji del sestavljeni v delavnici in se nato na terenu en za drugim v nizu namestijo na nosilno konstrukcijo zaletišča, na katerega se nastavljivo pritrdijo s pomočjo ustreznih vijačnih zvez, dočim so za njihovo nastavljanje po višini namenjeni elementi za uravnavanje v izvedbi navojnih palic, s katerimi so posamezni segmenti smučine opremljeni. Sistem za uravnavanje višine smučine se lahko izvede po celotni dolžini zaletišča skakalnice ali zgolj na njegovih posameznih delih. Hkrati je sistem za uravnavanje višine smučine razmeroma enostavne konstrukcije in s tem posledično enostaven za izdelavo ter montažo, kot tudi za rokovanje in vzdrževanje.The ski components with sliding channels and an external system for regulating them are manufactured and pre-assembled in the workshop and then mounted one after the other on a row on the supporting structure of the runway, to which they can be adjusted by means of suitable screw connections. height adjustment elements designed for adjusting the threaded rods with which individual segments of the ski are equipped. The ski height adjustment system can be implemented over the entire length of the ski jump surface or only on its individual parts. At the same time, the ski pitch control system is relatively simple in design and therefore easy to manufacture and install, as well as to handle and maintain.

Sestavni segmenti smučine z eksternim podložnim sistemom za uravnavanje njihove višine so en za drugim v nizu nameščeni in nastavljivo pritrjeni vzdolž cele dolžine nosilne konstrukcije zaletišča smučarske skakalnice ali zgolj na njenih posameznih odsekih. Nosilna konstrukcija je lahko jeklene, betonske ali kombinirane izvedbe.The ski components with an external washer system for adjusting their height are mounted one after the other in a series and are adjustably fixed along the entire length of the supporting structure of the ski jump site or only on its individual sections. The supporting structure can be steel, concrete or combined.

Segmenti smučine z drsnima kanaloma so preko vmesnih podložnih letev fiksno pritrjeni na prečne profile, ki so s pomočjo navojnih palic z maticami nastavljivo pritrjeni na pripadajoča sidrišča, ki so z vijaki fiksno pritrjena na površino nosilne konstrukcije smučarske skakalnice.Ski segments with sliding channels are fixed to the transverse profiles via intermediate washers, which are adjustable to the anchors by means of threaded nuts, which are fixed to the surface of the ski jump support structure by screws.

Višina posameznega prečnega profila se uravnava preko navojnih palic, pri čemer vsak prečni profil v predstavljenem izvedbenem primeru vsebuje štiri navojne palice. S pomočjo navojnih palic se uravnava višina in hkrati tudi horizontalni položaj posameznega prečnega profila, ter temu posledično tudi višina in vodoravnost smučine na zaletišču skakalnice, glede na njeno horizontalno os in predpisan profil skakalnice. V nekem drugem izvedbenem primeru, ki pa ni prikazan, je lahko drugačno število navojnih palic.The height of each transverse profile is adjusted by means of threaded rods, with each transverse profile having four threaded rods in the embodiment shown. With the help of threaded rods, the height and horizontal position of each transverse profile are regulated, and consequently the height and horizontalness of the ski at the jumping-off point of the ski jump, with respect to its horizontal axis and the prescribed jumping profile. In another embodiment, which is not shown, the number of threaded rods may be different.

Profil skakalnice je pogojen s profilom zaletišča skakalnice in jo določi projektant pri načrtovanju smučarske skakalnice. V naravi profil skakalnice predstavlja vrhnja površina znotraj drsnih kanalov v smučini, v katerih drsijo smuči skakalcev. Vrhnjo površino lahko predstavlja plast snega v smučini ali pa plast umetne smučine z keramičnimi čepi.The ski jump profile is conditioned by the ski jump start profile and determined by the designer when designing the ski jump. In nature, the profile of the ski jump is the upper surface inside the ski slides in which the skis of the ski jump. The upper surface can be represented by a layer of snow in the ski or a layer of artificial ski with ceramic studs.

Nosilna konstrukcija zaletišča skakalnice poteka pod profilom skakalnice in ji zaradi neravnin v betonu ali zaradi razmakov med jeklenimi profili običajno ni povsem vzporedna, zato je težko doseči popoln radij smučine na zaletišču. V teh primerih se uporabi eksterni podložni sistem po prijavljenem izumu, na katerega se pritrdi segmentna smučina. Na ta način se predhodno omenjene neravnine v nosilni konstrukciji zaletišča izničijo in omogočeno je doseganje popolne radialne krivulje smučine, ki je skladna profilu skakalnice oziroma predhodno opisanim profilom skakalnice. Sistem je uporaben tudi ob rekonstrukcijah skakalnic pri katerih je nosilna konstrukcija zaletišča poškodovana ali se je z obnovo spremenil tudi profil zaletišča in s tem tudi profil skakalnice.The load-bearing structure of the ski jump surface runs below the ski jump profile and is usually not completely parallel due to the unevenness of the concrete or because of the spacing between the steel profiles, which makes it difficult to obtain the perfect ski radius at the ski lift. In these cases, an external washer system of the present invention is used to which the segment ski is attached. In this way, the previously mentioned irregularities in the load-bearing structure of the runway are eliminated and it is possible to achieve a complete radial curve of the ski, which is consistent with the profile of the ski jump or the previously described ski jump profiles. The system is also useful for ski jumping reconstructions in which the load-bearing structure of the runway is damaged or when the runway profile and thus the jump profile are altered.

Z uporabo eksternega podložnega sistema za uravnavanje višine smučine po izumu odpadejo vsi posegi za odpravo nepravilnosti v obliki adaptacij nosilne konstrukcije zaletišča, hkrati pa odpade tudi vsakršna potreba po dvigovanju stvarne FIS linije, ki je predpisana s strani projektanta.The use of an external ski pitch control system according to the invention eliminates all interventions for eliminating irregularities in the form of adaptations of the load-bearing structure of the launch site, and at the same time eliminates any need to raise the actual FIS line prescribed by the designer.

Prednost eksternega podložnega sistema po izumu je tudi v večji aplikativnosti v primeru njegove vgradnje v že obstoječe nosilne konstrukcije zaletišč na skakalnicah. Tako lahko v primeru stare jeklene nosilne konstrukcije zaletišča navojne palice za nastavitev višine in regulacijo smučine vstavimo direktno v jekleno konstrukcijo in to brez uporabe sidrišč.The advantage of the external washer system according to the invention is also in its greater applicability in the case of its installation in the already existing load-bearing structures of the jumping areas. Thus, in the case of an old steel load-bearing structure, the threading bar for height adjustment and ski regulation can be inserted directly into the steel structure without the use of anchors.

V nadaljevanju bo eksterni podložni sistem za uravnavanje višine smučine smučarske skakalnice po izumu natančneje opisan na podlagi prednostnega izvedbenega primera s pomočjo slik, ki prikazujejoIn the following, the external ski jump height adjustment system of the ski jump according to the invention will be described in greater detail on the basis of a preferred embodiment by means of figures showing

Smučino smučarske skakalnice z eksternim podložnim sistemom za uravnavanje njene višine po prijavljenem izumu v bistvu tvori smučina 1, ki jo sestavlja poljubno število segmentov 2 do 2n z vzporedno izvedenima drsnima kanaloma 10 in 10.1, ki so v zaporednem in neprekinjenem nizu nameščeni vzdolž cele dolžine nosilne konstrukcije 9 zaletišča skakalnice. Dolžina zaletišča in s tem število segmentov 2 do 2n je določeno s FIS certifikatom oziroma s profilom smučarske skakalnice v primeru, da skakalnica nima homologacije.A ski jumping ski with an external washer system for adjusting its height according to the present invention is essentially formed by a ski 1 consisting of any number of segments 2 to 2n with parallel grooves 10 and 10.1 arranged in a continuous and continuous series along the entire length of the load carrier 9 jumping field structures. The length of the runway and thus the number of segments 2 to 2n is determined by the FIS certificate or the ski jump profile in the event that the ski jump is not approved.

Iz Sl 2 in Sl. 3 je razvidno, da eksterni podložni sistem za uravnavanje položaja smučine 1, oziroma vsakega njenega posameznega segmenta 2 do 2n, tvorijo podložna letev 3 s termoizolacijo 8, prečni profili 4, navojne palice 5 z neoznačenimi maticami in sidrišča 6 z vijaki 7.From FIG. 2 and FIG. 3 shows that the external washer system for adjusting the position of the ski 1, or each of its individual segments 2 to 2n, is formed by a base strip 3 with thermal insulation 8, cross sections 4, threaded bars 5 with unmarked nuts and anchors 6 with screws 7.

V obravnavanem izvedbenem primeru so segmenti 2 do 2n izdelani iz polietilena in so dimenzije 1000 x 625 mm. Po dolžini je vanje izvedenih deset lukenj za vgradnjo cevi hladilnega sistema, na drsni površini pa so vgrajeni keramični čepi, ki zmanjšujejo drsno površino in zagotavljajo minimalno trenje med smučjo in smučino. Na podložno letev 3 so segmenti 2 do 2n pritrjeni z vijakom ISO 7380 M8 x 25 A2. V nekem drugem izvedbenem primeru so lahko segmenti 2 do 2n izvedeni in pritrjeni tudi kako drugače.In the present embodiment, the segments 2 to 2n are made of polyethylene and are 1000 x 625 mm in size. There are ten holes for fitting the pipes of the cooling system in length, and ceramic plugs are installed on the sliding surface, which reduce the sliding surface and ensure minimal friction between the ski and the ski. The segments 2 to 2n are secured to the base 3 by an ISO 7380 M8 x 25 A2 screw. In another embodiment, the segments 2 to 2n may also be implemented and otherwise secured.

Posamezna podložna letev 3 je sestavljena iz jeklenih profilov dolžine 3000 mm in višine 25 mm tako, da skupna širina tega sestava znaša 630 mm. Vsaka podložna letev 3 nosi tri segmente 2 do 2n smučine 1 in je privita neposredno v prečni profil 4 z vijakom ISO 7380 M8 x 25 ZN. V nekem drugem izvedbenem primeru lahko podložna letev 3 nosi tudi več ali manj segmentov 2 do 2n.The individual base strip 3 consists of steel profiles of 3000 mm length and 25 mm height, with a total width of 630 mm. Each washer 3 bears three segments 2 to 2n of ski 1 and is screwed directly into the transverse profile 4 with an ISO 7380 M8 x 25 UN screw. In another embodiment, the base strip 3 may also carry more or less segments 2 to 2n.

Prečni profili 4 so dolžine do 2500 mm in višine 40 mm ter so izdelani in 3 mm pločevine. Širina prečnih profilov 4 je definirana s širino varnostnega koridorja, ki predstavlja območje med notranjima steklenima ograjama na zaletišču in se izračuna po posebni formuli, ki vključuje dolžino naleta. Stojijo na štirih navojnih palicah 5, katerih regulacija omogoča nastavitev njihove vodoravne lege in želene višine, glede na profil smučarske skakalnice. Prednostno se prečni profili 4 vgrajujejo na medsebojni razdalji 750 mm. V nekem drugem izvedbenem primeru so lahko prečni profili 4 podprti tudi z večjim ali manjšim številom navojnih palic 5, pri čemer so lahko prečni profili 4 izvedeni in vgrajeni tudi kako drugače.The transversal profiles 4 are up to 2500 mm long and 40 mm high and are made of 3 mm sheet metal. The width of the transversal profiles 4 is defined by the width of the security corridor, which represents the area between the inner glass railings at the launch site and is calculated using a special formula that includes the length of the collision. They are mounted on four threaded bars 5, whose regulation allows them to adjust their horizontal position and the desired height, according to the profile of the ski jump. Preferably, the transversal profiles 4 are mounted at a distance of 750 mm. In another embodiment, the transverse profiles 4 may also be supported by a larger or smaller number of threaded rods 5, wherein the transverse profiles 4 may be constructed and fitted in some other way.

Uporabljene so navojne palice 5 M20 dolžine od 240 mm do 330 mm, odvisno od želene višinske regulacije smučine 1. Pri navojnih palicah 5 dolžine 240 mm omogoča sistem po izumu regulacijo višine segmentov 2 do 2n v območju od 325 mm do 475 mm, pri njihovi dolžini 330 mm pa v območju od 415 mm do 565 mm. V nekem drugem izvedbenem primeru so lahko uporabljene tudi navojne palice 5 drugačne izvedbe in dimenzij.Depending on the desired height regulation of ski 1, 5 M20 threaded rods of length 240 mm to 330 mm are used. In the case of threaded rods 5 240 mm in length, the system according to the invention allows the height of segments 2 to 2n in the range of 325 mm to 475 mm to be regulated at 330 mm in length, ranging from 415 mm to 565 mm. In another embodiment, threaded bars 5 of a different design and dimensions may also be used.

Sidrišča 6 so v primeru betonske konstrukcije iz jeklene cevi višine 150 mm in dolžine 150 mm. V primeru jeklene nosilne konstrukcije so sidrišča 6 izvedena kot primarni element nosilne konstrukcije 9, na primer kot HEA profil v katerega se vstavljajo navojne palice 5 v predhodno pripravljene luknje dimenzije 25 mm. Za pritrjevanje posameznega sidrišča 6 na betonsko nosilno konstrukcijo 9 se uporablja vijak HUS3 HF 10X100 mm, pri čemer je potrebno pred vijačenjem vanje izvrtati luknje 10 mm. V nekem drugem izvedbenem primeru so lahko sidrišča 6 izvedena in vgrajena tudi kako drugače.The anchors 6 are 150 mm high and 150 mm long in the case of a concrete steel pipe structure. In the case of a steel load-bearing structure, the anchors 6 are designed as the primary element of the load-bearing structure 9, for example as a HEA profile into which threaded rods 5 are inserted into pre-prepared holes of 25 mm. A HUS3 HF 10X100 mm screw is used to attach anchorage 6 to the concrete structure 9, with 10 mm holes being drilled before screwing. In another embodiment, the anchorages 6 may be constructed and installed in some other way.

Termoizolacija 8 je nameščena pod segmente 2 do 2n smučine 1. V ta namen so uporabljene termoizolacijske plošče stirodur debeline 30 mm in debeline 20 mm. Termoizolacijske plošče debeline 20 mm so vstavljene pod podložno letev 3, dočim so debeline 30 mm vstavljene med prečne profile 4. Dimenzije izolacijskih plošč termoizolacije 8 so praviloma prilagojene razdaljam med prečnimi profili 4.Thermal insulation 8 is installed under segments 2 to 2n of ski 1. For this purpose, thermal insulation boards of 30 mm thick and 20 mm thick styrodur plates are used. Thermal insulation panels of 20 mm thickness are inserted under the base plate 3, while 30 mm thicknesses are inserted between the transverse profiles 4. The dimensions of the thermal insulation panels 8 are generally adapted to the distances between the transverse profiles 4.

Segmenti 2 do 2n so poljubnih dolžin in so v tesnem stiku nameščeni na in vzdolž podložne letve 3 s termoizolacijo 8 in so nanjo ustrezno pritrjeni tako, da oblikujejo smučino 1 z drsnima kanaloma 10 in 10.1. Prednostno je podložna letev 3 s termoizolacijo 8 nekoliko večje širine od širine segmentov 2 do 2n in je lahko izvedena iz enega ali iz več med sabo spojenih kosov.Segments 2 to 2n are of any length and are in close contact with and placed on and along the base strip 3 with thermal insulation 8 and are properly secured thereto to form a ski 1 with sliding channels 10 and 10.1. Preferably, the baseboard 3 with thermal insulation 8 is slightly larger than the width of the segments 2 to 2n and can be made of one or more jointed pieces.

Segmenti 2 do 2n s podložno letvijo 3 in termoizolacijo 8 so nameščeni in pritrjeni na prečne profile 4, ki so preko navojnih palic 5 vertikalno nastavljivo spojeni s sidrišči 6, katera so s pomočjo vijakov 7 fiksno spojena oziroma pritrjena na nosilno konstrukcijo 9 zaletišča.Segments 2 to 2n with washer 3 and thermal insulation 8 are mounted and secured to the transverse profiles 4, which are vertically adjustable to the anchors 6 through the threaded bars 5, which are fixedly connected to the supporting structure 9 by means of screws 7.

Kot je predhodno že opisano, so sestavni segmenti 2 do 2n smučine 1 en za drugim v nizu nameščeni in pritrjeni na podložno letev 3 s pomočjo ustreznih vijakov, ki pa niso prikazani. Segmenti 2 do 2n s podložnimi letvami 3 se, glede na določen profil skakalnice, uravnavajo po višini s prilagajanjem oziroma nastavitvijo višine vsakega posameznega prečnega profila 4 na katerega so pritrjeni. V ta namen služijo navojne palice 5, ki so vsaka zase vertikalno gibljivo nameščene v pripadajoče sidrišče 6, preko katerih je predstavljeni podložni sistem fiksiran na površino nosilne konstrukcije 9 z vijaki 7. Za obravnavani izvedbeni primer velja, da vsakemu prečnemu profilu 4 pripadajo štiri navojne palice 5 in sicer po dve na vsaki strani smučine 1. Kot že rečeno, je lahko v nekem drugem izvedbenem primeru število navojnih palic 5 tudi večje ali manjše od predhodno omenjenega števila.As previously described, the component segments 2 to 2n of ski 1, one after the other in a row, are mounted and fixed to the base 3 by means of suitable screws, which are not shown. Segments 2 to 2n with laths 3 are, according to a certain jump profile, adjusted in height by adjusting or adjusting the height of each individual transverse profile 4 to which they are attached. For this purpose, threaded rods 5, each of which are vertically movably mounted in their respective anchorage 6, through which the presented washer system is fixed to the surface of the supporting structure 9 by screws 7. For the present embodiment, each transversal profile 4 is said to have four threaded members bars 5, two on each side of ski 1. As already stated, in another embodiment, the number of threaded bars 5 may also be greater than or less than the previously mentioned number.

Razen višine smučine 1 oziroma vanjo integriranih segmentov 2 do 2n se lahko s sistemom po izumu uravnava tudi njihova horizontalna lega, kar prav tako dosežemo s pomočjo nastavitve posameznih prečnih profilov 4 ob pomoči navojnih palic 5.In addition to the height of the ski 1 or the segments 2 to 2n integrated therein, the horizontal position of the system according to the invention can also be adjusted, which is also achieved by adjusting the individual cross sections 4 with the help of threaded bars 5.

Iz opisanega sledi, da je mogoče z eksternim podložnim sistemom po izumu smučino 1 uravnavati oziroma nastavljati hkrati v vertikalni in horizontalni smeri, glede na vzdolžno in prečno os čelne ploskve nosilne konstrukcije 9 zaletišča skakalnice.It follows from the foregoing that with the external washer system according to the invention, the ski 1 can be adjusted or adjusted simultaneously in the vertical and horizontal directions, respectively, with respect to the longitudinal and transverse axes of the front surface of the supporting structure 9 of the ski jump start.

Prednost eksternega podložnega sistema po izumu je tudi v večji aplikativnosti v primeru njegove vgradnje v že obstoječe nosilne konstrukcije 9 zaletišč na skakalnicah. Tako lahko v primeru stare jeklene nosilne konstrukcije 9 zaletišča navojne palice 5 za nastavitev višine in regulacijo smučine 1 vstavimo direktno v jekleno nosilno konstrukcijo 9 in to brez uporabe sidrišč 6.The advantage of the external washer system according to the invention is also greater applicability in the case of its incorporation into already existing load-bearing structures of 9 jump sites. Thus, in the case of an old steel support structure 9, the starters of the threaded rod 5 for height adjustment and ski regulation 1 can be inserted directly into the steel support structure 9 without using anchors 6.

V nadaljevanju je opisan postopek montaže segmentov 2 do 2n smučine 1 s podložnim sistemom za njihovo uravnavanje po izumu, ki poteka po naslednjih korakih:The following describes the procedure for mounting segments 2 to 2n of ski 1 with a washer system for regulating them according to the invention, which is performed in the following steps:

a/ v nosilno konstrukcijo 9 se, na osnovi predhodno geodetsko oblikovane mreže točk, zvrtajo luknje, ki služijo za pritrditev sidrišč 6 s pomočjo vijakov 7, b/ po pritrditvi sidrišč 6 se njihove višine izmerijo z ustreznim instrumentom, nakar se višinske razlike med sidrišči 6 izničijo z uravnavanjem navojnih palic 5, pri čemer se za vsako zmed njih določi razdalja od določenega profila skakalnice, kar v obravnavanem izvedbenem primeru znaša 85 mm, c/ nato se preko navojnih palic 5 v sidrišča 6 vstavijo prečni profili 4 in navojne palice 5 se privijejo oziroma fiksirajo, ko je višina prečnih profilov 4 enaka izračunani razdalji iz predhodnega koraka torej, ko so zgornje ploskve prečnih profilov 4 za 85 mm nižje od profila skakalnice, d/ ko so prečni profili 4 pritrjeni na ustrezni višini, se prav tako s pomočjo tahimetra določi in začrta linija, ki je za 320 mm zamaknjena od vzdolžne osi nosilne konstrukcije 9 zaletišča skakalnice, kar pomeni, da se na vsak prečni profil 4 zariše črta, ki je 320 mm odmaknjena od omenjene vzdolžne osi nosilne konstrukcije 9, e/ sledi vgradnja podložnih letev 3 tako, da se njihova vzdolžna stranska robova približata črti na prečnih profilih 4 iz predhodnega koraka s čimer se doseže, da leži vzdolžna središčna os sleherne podložne letve 3 natanko v liniji vzdolžne središčne osi zaletišča skakalnice oziroma njene nosilne konstrukcije 9, f/ temu sledi vgradnja segmentov 2 do 2n smučine 1, po kateri smučine 1 ni več mogoče premikati levo ali desno glede na vzdolžno os nosilne konstrukcije 9 oziroma vzdolžno os zaletišča, s čimer se posledično doseže, da leži smučina 1 natančno v vzdolžni osi skakalnice, g/ po končani vgradnji segmentov 2 do 2n se po potrebi dvigne ali spusti še kakšen od prečnih profilov 4 tako, da dosežemo linijo smučine 1, ki je skladna s profilom smučarske skakalnice.a / in the supporting structure 9, holes based on geodetically formed grid of points are drilled for fixing the anchorages 6 by means of screws 7; b / after fixing the anchorages 6, their heights are measured with a suitable instrument, after which the height differences between the anchorages are measured 6 is eliminated by adjusting the threaded bars 5, for each of which a distance from a certain jump profile is determined, which in the present embodiment is 85 mm, c / then transverse profiles 4 and threaded bars 5 are inserted into the anchors 6. are screwed in or fixed when the height of the transversal profiles 4 is equal to the calculated distance from the previous step, ie when the upper surfaces of the transverse profiles 4 are 85 mm lower than the jump profile, d / when the transverse profiles 4 are fixed at the appropriate height, also with by means of a tachymeter the line drawn 320 mm offset from the longitudinal axis of the supporting structure 9 of the jumping-off point of the jumping jump is determined, which means that at each transverse profile 4 is drawn by a line 320 mm offset from said longitudinal axis of the supporting structure 9, e / followed by the installation of washers 3 such that their longitudinal lateral edges approach the line on the transverse profiles 4 from the previous step, thereby achieving that lies the longitudinal center axis of each base rail 3 exactly in line with the longitudinal center axis of the jumping field or its supporting structure 9, f / followed by the installation of segments 2 to 2n of ski 1, by which ski 1 can no longer be moved left or right relative to the longitudinal axis of the ski carrier of construction 9 or the longitudinal axis of the runway, thereby achieving the ski 1 exactly in the longitudinal axis of the ski jump, g / after the installation of segments 2 to 2n, if necessary, raise or lower any of the transversal profiles 4 so as to reach the ski line 1, which is consistent with the profile of the ski jump.

Navojne palice 5 so v prikazanem izvedbenem primeru izvedene kot stojni vijaki s pripadajočimi maticami, ki pa so lahko v nekem drugem izvedbenem primeru tudi drugačne izvedbe.In the embodiment shown, the threaded rods 5 are constructed as stand screws with associated nuts, which may, however, be of a different embodiment in another embodiment.

Sidrišča 6 so izvedena iz votlega profila kvadratnega prečnega preseka in so lahko v nekem drugem izvedbenem primeru izvedena tudi iz profilov drugačnega preseka.Anchors 6 are derived from a hollow square cross-section profile and, in another embodiment, may also be derived from profiles of a different cross-section.

Pri smučini smučarske skakalnice z eksternim podložnim sistemom za uravnavanje višine smučine 1 po izumu je po višini nastavljiv sleherni predhodno pritrjeni segment 2 do 2n in to neodvisno od drugih segmentov 2 do 2n v zaporednem nizu. To omogočajo sidrišča 6 z navojnimi palicami 5 in pripadajočimi maticami. S privijanjem ali odvijanjem navojnih palic 5 lahko določeni segment 2 ali 2n dvigujemo od ali spuščamo bliže nosilni konstrukciji 9.In the case of a ski jumping ski with an external washer system for adjusting the pitch of ski 1 according to the invention, each pre-secured segment 2 to 2n is adjustable in height, independently of other segments 2 to 2n in a series. This is facilitated by anchors 6 with threaded rods 5 and associated nuts. By screwing or unscrewing the threaded rods 5, a particular segment 2 or 2n can be lifted from or lowered closer to the supporting structure 9.
