Description

SISTEM ZLOŽLJIVE OGRAJE NA ODSKOČNI MIZI SMUČARSKE SKAKALNICEFOLDING FENCE SYSTEM ON THE JUMPING TABLE OF THE SKI JUMP

Predmet izumaThe subject of the invention

Predmet izuma je sistem zložljive ograje primeren za vgradnjo na odskočno mizo smučarske skakalnice oziroma natančneje sistem zložljive ograje, ki omogoča, da ograja v osnovni, vertikalni legi varuje vzdrževalce ob hoji po stopnicah in tekmovalce ob morebitnem padcu v smučini, v sekundarni, horizontalni legi pa omogoča prost pogled trenerjem na tekmovalca v fazi odskoka, obenem pa še vedno varuje tekmovalce ob morebitnem padcu v smučini.The subject of the invention is a system of folding fence suitable for installation on the springboard of a ski jump, or more precisely a system of folding fence, which enables the fence in the basic, vertical position to protect maintainers when walking up stairs and competitors in the event of a fall in the ski. it allows coaches to have a free view of the competitor in the rebound phase, while still protecting the competitors in the event of a fall in skiing.

Tehnični problemTechnical problem

Problem, ki ga rešuje tako zasnovan sistem ograje na odskočni mizi smučarske skakalnice, je neoviran pogled trenerja s trenerske tribune na tekmovalca v fazi odskoka. Odskok je eden ključnih elementov smučarskih skokov, zato je toliko bolj pomembno, da ima trener omogočen neoviran pogled na tekmovalca. Pri sodobnih smučarskih skakalnicah opažamo problem, da ima nemalo objektov na koncu zaletišča vgrajeno ograjo, ki onemogoča jasen pogled trenerja na odskočno mizo. Vgradnja sistema zložljive ograje na delu odskočne mize pa ta problem rešuje, saj ograja v sekundarnem položaju trenerjem omogoča neoviran pogled s trenerske tribune, v primarnem položaju pa opravlja svojo osnovno funkcijo, torej varovanje ljudi, ki se zadržujejo na območju odskočne mize pred padcem v globino.The problem solved by such a design of the fence system on the springboard of the ski jump is the unobstructed view of the coach from the coaching tribune on the competitor in the bounce phase. Bounce is one of the key elements of ski jumping, so it is all the more important that the coach has an unobstructed view of the competitor. In modern ski jumps, we notice the problem that quite a few facilities at the end of the runway have a built-in fence, which prevents a clear view of the coach on the springboard. The installation of a folding fence system on the part of the springboard solves this problem, as the fence in the secondary position allows coaches an unobstructed view from the coach's stand, and in the primary position it performs its basic function, ie protecting people staying in the springboard area. .

Stanje tehnikeState of the art

Po patentnem dokumentu US7523921B2 je znan primer sistema zložljive ograje primerne za ustvarjanje zasebnosti oziroma varovanje imetja in varovanje ljudi pred padci v globino. Namen sistema zlaganja ograje opisanega v omenjenem patentnem dokumentu je predvsem postavitev ograje v horizontalni oziroma sekundarni položaj v primeru vremenskih ujem, predvsem močnega vetra in s tem zaščita ograje pred uničenjem. Njegovo slabost v največji meri predstavljajo fiksni vertikalni stebri, ki v sekundarnem položaju ograje še vedno zavzemajo vertikalno lego, to pa ne ustreza aplikacijam, kjer z zlaganjem ograje želimo doseči predvsem neoviran pogled. Naslednja slabost te rešitve je tudi pritrjevanje ograje v vertikalno oziroma primarno lego, ki je izvedeno s krilnimi maticami in namensko izdelanim nosilcem. Tak način pritrjevanja je izredno zamuden, prav tako pa vsebuje veliko sestavnih delov. Opisani sistem nima implementiranega nikakršnega mehanizma, ki bi uporabniku pomagal premikati breme med prestavljanjem ograje iz primarnega v sekundarni položaj ali obratno, kar bi prav tako veljalo izpostavti za eno od slabosti sistema.Patent document US7523921B2 discloses an example of a folding fence system suitable for creating privacy or protecting property and protecting people from falling into the depths. The purpose of the fence stacking system described in the mentioned patent document is primarily to place the fence in a horizontal or secondary position in case of weather, especially strong winds and thus protect the fence from destruction. Its disadvantage is mainly due to the fixed vertical columns, which in the secondary position of the fence still occupy a vertical position, but this does not correspond to applications where by folding the fence we want to achieve an unobstructed view. Another disadvantage of this solution is the attachment of the fence to the vertical or primary position, which is done with wing nuts and a specially designed bracket. This method of attachment is extremely time consuming and also contains many components. The described system does not have any mechanism implemented to help the user move the load during the movement of the fence from the primary to the secondary position or vice versa, which would also be worth pointing out as one of the weaknesses of the system.

Na podlagi predhodno opisane znane rešitve sistema zložljive ograje obstaja nerešen problem, kako zasnovati in izvesti sistem zložljive ograje, ki v celoti zavzame sekundarni oziroma horizontalni položaj in v tem položaju s svojimi elementi ne ustvarja vertikalnih vizualnih preprek. Takšen sistem zlaganja bo izveden brez dodatnih oziroma odvečnih sestavnih delov, ki so potrebni za pritrditev ograje v primarno ali v sekundarno lego, kar bo občutno skarjšalo čas potreben za premik ograje iz primarne v sekundarno lego ali obratno. Dalje bo ta sistem vseboval mezanizem s plinskimi vzmetmi, ki bo uporabniku omogočal lažje dvigovanje ograje v primarno lego oziroma spuščanje le-te v sekundarno lego. S tem bo sistem varnejši za uporabo. Sistem bo vseboval tudi mehanizem, ki bo omogočal nastavitev kota v sekundarni legi med 0° in 25°, s tem bo sistem opravljal varovalno funkcijo tudi v sekundarnem položaju.Based on the previously described known solution of the folding fence system, there is an unsolved problem of how to design and implement a folding fence system that fully occupies a secondary or horizontal position and does not create vertical visual barriers with its elements in this position. Such a stacking system will be implemented without additional or redundant components required to attach the fence to the primary or secondary position, which will significantly reduce the time required to move the fence from the primary to the secondary position or vice versa. Furthermore, this system will contain a mechanism with gas springs, which will enable the user to more easily raise the fence to the primary position or lower it to the secondary position. This will make the system safer to use. The system will also contain a mechanism that will allow you to adjust the angle in the secondary position between 0 ° and 25 °, so the system will perform a protective function even in the secondary position.

Opis izumaDescription of the invention

Rešitev predhodno opisanega tehničnega problema je zasnovana na inovativni konstrukciji sistema zložljive ograje na odskočni mizi smučarske skakalnice. Sistem je zasnovan tako, da je lahko vgrajen na jekleno, leseno ali betonsko osnovno konstrukcijo smučarske skakalnice oziroma mize smučarske skakalnice. Posamezni sestavni deli so predhodno izdelani v delavnici, kar omogoča hitro izvedbo vgradnje na terenu.The solution to the previously described technical problem is based on the innovative construction of a folding fence system on the ski jump springboard. The system is designed so that it can be installed on a steel, wooden or concrete basic structure of the ski jump or ski jump table. The individual components are prefabricated in the workshop, which enables quick installation in the field.

Zložljiva ograja ima modularno zasnovo, kar pomeni, da lahko ograjo nizamo v segmentih dolžine 150 cm, odvisno od potreb posameznega objekta. Običajno sistem sestoji iz štirih segmentov, skupne dolžine 6 m, kar ustreza dolžini odskočne mize vseh večjih sodobnih skakalnic, za manjše in male skakalnice je število segmentov ustrezno manjše.The folding fence has a modular design, which means that the fence can be arranged in segments of 150 cm in length, depending on the needs of each building. Typically, the system consists of four segments, a total length of 6 m, which corresponds to the length of the springboard of all major modern jumps, for smaller and small jumps, the number of segments is correspondingly smaller.

V spodaj opisanem prednostnem izvedbenem primeru sistema zložljive ograje segment sestavljajo trije nosilni stebri in dve horizontalni ojačitvi, prostor med vertikalnimi nosilci zapolnjuje napeta žična vrv. V nekem drugem izvedbenem primeru so lahko namesto žičnih vrvi uporabljene tudi lesene deske, paneli iz ekspandirane pločevine, jeklena rešetka, paneli iz umetne mase ali kakšen drug ustrezen material. Tovrstna možnost izbre vgrajenega materiala na nosilne stebre segmenta omogoča, da pri obstoječih objektih lahko sistem zložljive ograje stilsko uskladimo z obstoječo ograjo.In the preferred embodiment of the folding fence system described below, the segment consists of three load-bearing columns and two horizontal reinforcements, the space between the vertical beams being filled by a tensioned wire rope. In another embodiment, wooden boards, expanded sheet metal panels, steel grille, plastic panels or any other suitable material may be used instead of wire ropes. This type of choice of built-in material on the load-bearing columns of the segment enables the system of a folding fence to be stylistically coordinated with the existing fence in the case of existing buildings.

Vsak segment obravnavanavanega sistema je na obstoječo konstrukcijo pritrjen na šestih točkah preko ustreznih vijačnih vezi. Vsak nosilni stebr posameznega segmenta za pravilno delovanje, torej zlaganje, potrebuje vpetje v dveh točkah, in sicer je v prvi točki vpet nosilec vertikalnega stebra, ki je obenem tudi točka vrtišča ograje, v drugi točki pa je vpet nosilec plinske vzmeti. Omenjeni točki sta v čelnem pogledu nameščeni ena za drugo na točno določeni razdalji, ki ustreza dolžini plinske vzmeti in omogoča njeno delovanje oziroma ena ob drugi v stranskem pogledu, dalje so vpetja posameznega nosilnega stebra (dve točki vpetja) nizana vzporedno vzdolž zaletišča smučarske skakalnice.Each segment of the considered system is attached to the existing structure at six points via appropriate screw connections. Each load-bearing column of an individual segment needs to be clamped at two points for proper operation, ie folding, namely the support of the vertical column support at the first point, which is also the pivot point of the fence, and the gas spring support at the second point. In the front view, these points are placed one behind the other at a specific distance that corresponds to the length of the gas spring and enables its operation or side by side in the side view.

Plinska vzmet omogoča uporabniku spreminjanje položaja ograje iz primarne v sekundarno lego brez pretiranih naporov. Pri dvigovanju ograje iz horizontalne oziroma sekundarne v vertikalno oziroma primarno lego plinska vzmet pomaga dvigovati breme. Med spuščanjem iz primarne v sekundarno lego pa zadržuje oziroma upočasnjuje segment ograje in s tem preprečuje morebine poškodbe, do katerih bi lahko pripeljal nenaden premik segmenta iz primarne v sekundarno lego.The gas spring allows the user to change the position of the fence from the primary to the secondary position without excessive effort. When lifting the fence from the horizontal or secondary to the vertical or primary position, the gas spring helps to lift the load. During the descent from the primary to the secondary position, it retains or slows down the segment of the fence and thus prevents any damage that could lead to a sudden movement of the segment from the primary to the secondary position.

Ograjo v primarni legi zadrži namensko izdelani zatič, ki je vstavlen skozi izvrtino v na desni stranski ploskvi noslca vertikalnega stebra in preko izvrtin na vertikalnem stebru doseže desno stransko ploskev nosilca vertikalnega stebra.The fence is held in its primary position by a purpose-built pin, which is inserted through a hole in the right side surface of the vertical column girder and reaches the right side surface of the vertical column girder through the holes in the vertical column.

Višina segmenta varovalne ograje v prednostnem izvedbenem primeru je 160 cm, kar ustreza zahtevam mednarodne smučarske zveze FIS, poleg tega ja omenjena višina v večini primerov primerna tudi za vgradnjo luči na vrh segmenta varovalne ograje, brez vgradnje dodatnih nosilcev, kar zmanjša stroške investicije. Vertikalni steber nosline ograje je izdelan iz votle cevi, kar omogoča vgradnjo električnih vodov, brez dodatnih kabelskih polic, ki kazijo končni izgled ograje.The height of the guardrail segment in the preferred embodiment is 160 cm, which corresponds to the requirements of the International Ski Federation FIS. The vertical pillar of the fence support is made of a hollow tube, which allows the installation of electrical lines, without additional cable shelves, which spoil the final appearance of the fence.

Prednost sistema zložljive varovalne ograje po izumu je v večji aplikativnosti pri vgradnji na že obstoječe skakalnice, saj pri uporabi materiala za varovalni panel segmenta, tako rekoč ni omejitev, dalje lahko zunanji izgled vskladimo z že obstoječim delom.The advantage of the folding guardrail system according to the invention is its greater applicability when installed on already existing jumps, since there are virtually no restrictions on the use of material for the segment's security panel.

Zložljivo ograjo po prijavljenem izumu v bistvu tvori segment ograje 1, ki ga lahko nizamo v poljubnem številu vzdolž zaletišča smučarske skakalnice. Segment ograje 1 je sestavljeni iz treh vertikalnih stebrov ograje 2 in dveh horizontalnih ojačitev 12. Vertikalni steber ograje 2 je izdelan iz jeklene cevi 60 x 60 mm, v prednostnem izvedbenem primeru dolžine 1600 mm, v kakšnem drugem primeru se lahko dolžina in uporabljena cev razlikuje. Horizontalna ojačitev je izdelana iz jeklene cevi 50 x 50 mm dolžine 1440 mm. Vertikalni steber ograje 2 in horizontalna ojačitev 12 sta v prednostnem izvedbenem primeru zvarjena skupaj, v drugem izvedbenem primeru sta lahko povezana tudi z ustrezno vijačeno vezjo. Segmetn ograje 1 je pred rjo zaščiten z vročim cinkanjem.The folding fence according to the present invention essentially forms a segment of the fence 1, which can be arranged in any number along the runway of the ski jump. The fence segment 1 consists of three vertical fence posts 2 and two horizontal reinforcements 12. The vertical fence post 2 is made of 60 x 60 mm steel pipe, in a preferred embodiment 1600 mm in length, in which other case the length and pipe used may differ . The horizontal reinforcement is made of steel pipe 50 x 50 mm with a length of 1440 mm. The vertical fence post 2 and the horizontal reinforcement 12 are welded together in a preferred embodiment, in another embodiment they can also be connected by a suitable screw circuit. The fence segment 1 is protected against rust by hot-dip galvanizing.

Prostor med vertikalnimi stebri ograje 2 je lahko zaprt s poljubnim materialom, v prednostnem izvedbenem primeru je uporabljena žična vrv 13, uporabljena je žična vrv tipa F, debeline 5 mm, s sedmimi jedri po 19 žic oz. krajše 7x19. Žična vrv 13 je napeta skozi izvrtine za vpetje žične vrvi 11 v vertikalnem stebru ograje.The space between the vertical posts of the fence 2 can be closed with any material, in a preferred embodiment a wire rope 13 is used, a wire rope type F, 5 mm thick, with seven cores of 19 wires or shorter 7x19. The wire rope 13 is tensioned through the holes for clamping the wire rope 11 in the vertical column of the fence.

Segment ograje 1 je vpet v vpetje vertikalnega stebra ograje 3, vpetje je izdelano iz jekla, dalje je z vročim cinkom zaščiteno pred korozijo. Vertikalni steber in vpetje povezuje os vrtenja 5, za os vrtenja je uporabljen vijak M16x110 DIN 931, samovarovalna matica M16 DIN 985 in pripadajoč neoznačen vijačni material; štiri široke podložke M16 DIN 7093. Stranski ploskvi vpetja vertikalnega nosilca ograje imata izdelani izvrtini dimenzije 17 mm, prav tako ima izvrtini dimenzije 17 mm izdelan tudi vertikalni stebr ograje. Os vtrenja 5 je tako vstavljena skozi levo stransko ploskev vpetja preko votle cevi stebra skozi desno stransko ploskev nosilca vpetja, kjer je na zunanji strani pritrjena s samovarovalno matico 16.The segment of the fence 1 is clamped in the clamp of the vertical column of the fence 3, the clamp is made of steel, further it is protected against corrosion with hot zinc. The vertical column and the clamp are connected by the axis of rotation 5, for the axis of rotation the screw M16x110 DIN 931, the self-locking nut M16 DIN 985 and the corresponding unmarked screw material are used; four wide washers M16 DIN 7093. The side mounting surfaces of the vertical fence bracket have drilled holes of 17 mm, and the holes of 17 mm also have a vertical fence post. The axis of friction 5 is thus inserted through the left side surface of the mounting through the hollow tube of the column through the right side surface of the mounting bracket, where it is fastened on the outside with a self-locking nut 16.

Vpetje vertikalnega stebra 3 je na osnovno nosilno konstrukcijo 14, pritrjeno s štirimi vijaki za pritrditev segmenta na nosilno konstrukcijo 10 tipa M 12x50 DIN 931. V nekem drugem izvedbenem primeru je lahko vpetje vertikalnega stebra 3 na osnovno noslino konstrukcijo 14 pritrjeno tudi drugače.The mounting of the vertical column 3 is attached to the base support structure 14 with four screws for attaching the segment to the support structure 10 type M 12x50 DIN 931. In another embodiment, the mounting of the vertical column 3 to the base support structure 14 can be attached differently.

Vpetje vertikalnega stebra 3, sestavljajo še gumjast blažilec 7 in regulacijski vijak 8. Vloga gumjastega blažilca 7 je, da preprečuje neposreden udarec vertikalnega stebra ograje 2 ob vpetje vertikalnega stebra 3, takšen udarec poleg povzročanja hrupa, lahko tudi poškoduje protikorozijsko zaščito na obeh elementih, kar pomeni hitrejšo obrabo, ter posledično krajšo življenjsko dobo. Z regulacijskim vijakom 8, dimenzij M12x90 DIN 933, lahko določimo končno lego segmenta ograje 1 v sekundarnem položaju, v primeru da ne želimo, da segment zajema pozicijo 0°. Z privijanjem regulacijskega vijaka 8, segment ograje v horizontalni legi odmikamo od pozicjie 0°, dalje z odvijanjem regulacijskega vijaka 8 pa segment ograje približujemo poziciji 0° v horizontalni legi. Regulacijski vijak 8 omogoča lego med 0° in 25° v sekundarni legi.The clamp of the vertical column 3 also consists of a rubber damper 7 and a control screw 8. The role of the rubber damper 7 is to prevent a direct impact of the vertical column of the fence 2 against the mounting of the vertical column 3. which means faster wear and, consequently, shorter service life. With the adjusting screw 8, dimensions M12x90 DIN 933, we can determine the final position of the fence segment 1 in the secondary position, in case we do not want the segment to cover the 0 ° position. By tightening the adjusting screw 8, the fence segment is moved away from the 0 ° position, and further by unscrewing the adjusting screw 8, the fence segment is moved closer to the 0 ° position in the horizontal position. The adjusting screw 8 allows a position between 0 ° and 25 ° in the secondary position.

Poleg gumijastega blažilca 7 udarec vertikalnega stebra ob vpetje preprečuje tudi plinska vzmet 4, moči 500N. Plinska vzmet je na eni strani vpeta na vertikalni steber ograje, druga stran pa v namensko izdelan nosilec oziroma vpetje plinske vzmeti 9. Vzmet je na nosilec plinske vzmeti 9 in vpetje vertikalnega stebra 3, privijačena z neoznačenim vijačnim materialom. Vpetje plinske vzmeti je izdelano iz jekla, ki je protikorozijsko zaščiteno z vročim cinkom. Vpetje plinske vzmeti je na osnovno konstrukcijo privijačeno z vijakom za pritrditev segmenta na osnovno konstrukcijo vzmeti 10, v prednostnem izvedbenem primeru je uporabljen vijak M12x50 DIN933. V nekem drugem izvedbenem primeru je vpetje plinske vzmeti na nosilno konstrukcijo lahko izvedeno tudi drugače.In addition to the rubber shock absorber 7, the impact of the vertical column during clamping is also prevented by the gas spring 4, with a power of 500N. The gas spring is mounted on one side on the vertical pillar of the fence, and on the other side in a specially designed support or mounting of the gas spring 9. The spring is on the support of the gas spring 9 and the mounting of the vertical column 3, screwed with unmarked screw material. The gas spring clamp is made of steel, which is anti-corrosion protected with hot zinc. The gas spring mounting is screwed to the base structure with a screw for attaching the segment to the base spring structure 10, in the preferred embodiment an M12x50 DIN933 screw is used. In another embodiment, the attachment of the gas spring to the supporting structure can also be performed differently.

Ograjo v vertikalnem položaju zadrži zatič 6, ki se ga vstavi skozi izvrtino 15 na stranski ploskvi vpetja vertikalnega stebra 3, preko izvrtine 16 na vertikalnem stebru 2, v izvrtino 15 na nasprotni stranski ploskevi vpetja vertikalnega stebra, podobno kot pri osi vrtenja 5, le da gre v tem primeru za izvrtine dimenzije 12 mm.The fence is held in the vertical position by a pin 6, which is inserted through the hole 15 on the side surface of the vertical column 3, through the hole 16 on the vertical column 2, into the hole 15 on the opposite side surface of the vertical column, similar to the axis of rotation 5, only that in this case there are holes of dimension 12 mm.
