Abstract

The elongated ski solves the problem of optimising the ski during the ride straight ahead and the ride into curves. The elongated ski features at the back of the ski (6) an added narrower extended part of ski (7) and in the front a front extension of the ski (1), which finds expression during a ride straight ahead. On the front extension of the ski (1) and on the rear extension of the ski (7) there may not be any sharp edges.

PODALJŠANA SMUČKAEXTENDED SKI

Predmet izuma je podaljšana smučka, oziroma bolj natančno podaljšana smučka prednostno namenjena za uporabo na urejenih smučiščih, pri kateri smučar uporablja prednosti steptanega snega.The object of the invention is an extended ski, or more specifically an extended ski, preferably intended for use in landscaped ski resorts, in which the skier takes advantage of the snow.

Tehnični problem, ki ga rešuje predstavljeni izum, je takšna konstrukcija smučke namenjene za uporabo na smučiščih, ki omogoča čim večje hitrosti na ravnih delih smučarske steze in zagotavlja majhne radije pri zavijanju, ter pri tem dovoljuje doseganje višjih hitrosti kot do sedaj znane smučke in pri tem ne pride do nepredvidenih poškodb.A technical problem solved by the present invention is such a construction of the ski intended for use on ski slopes, which allows maximum speed on flat sections of the ski slope and provides small radii when cornering, while allowing higher speeds than hitherto known skis and at this does not result in unforeseen injuries.

Znanih rešitev smučk za smučanje po snežnih terenih je kar veliko. Smučanje je zimski šport, kije dostopen čedalje večjemu številu uporabnikov. Vedno bolj prihaja do delitve na posamezne discipline in pri tem tudi na delitve med amatersko in profesionalno rabo. Smuči so različno izdelane in imajo tudi različne performanse glede na kategorijo. Osnovna zahteva ostaja po čim bolj vami smučki, ki zagotavlja optimalno smučanje na ravninah, zavojih in strminah. Smuči s poudarjenim stranskim lokom so velik korak naprej. S svojo konstrukcijo omogočajo boljši stik s snegom in enostavnejšo vodljivost. Še posebej morajo biti smuči optimalno izdelane za tekmovalno rabo, kjer o uvrstitvi med prve ali zadnje odločajo že malenkosti..There are many known solutions for skiing in the snow. Skiing is a winter sport accessible to an increasing number of users. Increasingly, there is a division into different disciplines, and also between amateur and professional uses. The skis are differently made and also have different performances depending on the category. The basic requirement remains that you ski as much as possible, ensuring optimal skiing on planes, turns and slopes. Ski with a prominent side arch is a big step forward. With their construction, they allow for better snow contact and easier handling. In particular, skis should be optimally designed for competitive use, where the ranking of first or last is already decided by a few things.

Ne glede na razne delitve mora posamezna smučka zagotavljati kvalitetno vožnjo naravnost in kvalitetno zavijanje. Vožnja naravnost zahteva čim večjo dolžino celotne drsne ploskve smučke, saj je takrat manjše trenje, kar omogoča večje hitrosti. Klasičen primer ozke in dolge smučke je tekaška smučka, ki izkorišča čim manjšo širino ob veliki dolžini, kar se odraža v majhni porabi energije tekača pri premikanju.Regardless of the various divisions, each ski must ensure a good ride with a straight and good turn. Riding straight requires the maximum length of the entire skid surface of the ski, since there is less friction at the time, allowing for faster speeds. A classic example of a narrow and long ski is a cross-country ski that utilizes as little width as possible over a large length, which is reflected in the low energy consumption of the runner when moving.

V nasprotju z zahtevami za vožnjo naravnost so pogoji zavijanja, kjer mora biti smučka krajša in mora zagotavljati učinkovito vožnjo po robnikih. Pri tem pridejo do izraza predvsem notranji robniki. Težnja pri smučanju je čim bolj enostavna vožnja, ki zahteva minimalne motorične sposobnosti ali vsaj zagotavlja optimalen izkoristek vseh motoričnih sposobnosti.Contrary to the requirements for running straight, there are turning conditions where the ski has to be shorter and to ensure efficient running on the curbs. This is mainly due to the inner edges. The tendency to ski is as simple as possible, which requires minimal motor skills or at least ensures optimal utilization of all motor skills.

V določenih pogojih bi bilo zaželjeno, daje uporabnik smuči čim lažji, na drugem delu smučarske proge bi bilo bolje, če je uporabnik smuči težji. Teže smučarja se med vožnjo ne da spreminjati, zato se parametre optimalne teže kompenzira z dolžino smuči in parametri trdote smuči.In certain conditions, it would be desirable for the ski user to be as light as possible, while on the other part of the ski run it would be preferable for the ski user to be heavier. The weight of the skier cannot be changed while driving, so the parameters of the optimal weight are compensated by the length of the skis and the parameters of the hardness of the skis.

Dosedanje konstrukcije smuči so kompromis med zahtevami za vožnjo naravnost in zavijanjem.The ski designs so far are a trade-off between the demands of running straight and turning.

Enake razmere veljajo tudi pri uporabi smučarske deske.The same conditions apply when using a ski board.

Problem, ki je ostal nerešen je uporaba posameznih prednosti smuči, kjer je pri vožnji naravnost to dolžina smuči in pri zavijanju uporaba kratkih smuči s poudarkom na vožnji po robnikih.The problem that remains unresolved is the use of individual advantages of the ski, where when driving straight this is the length of the ski and when cornering the use of short skis with a focus on curb riding.

Tehnični problem je rešen po izumu tako, da je podaljšana smučka izdelana iz osnovnega dela in podaljška, ki sta že pri postopku izdelave neločljivo povezana in predstavljata čvrsto celoto. Osnovnemu konstrukcijskemu delu smučke, ki je primemo izbran model smučke za vožnjo po snegu, je dodan podaljšek smučke. Podaljšek smučke ima manjšo širino kot osnovni del smučke. Pri vožnji naravnost osnovni del smučke in podaljšek smučke enakomerno drsita po snegu s celotno drsno ploskvo. V primeru zavijanja, katerega značilnost je vožnja po robnikih je v stiku s snegom samo osnovni del smučke. Ožji podaljšek smučke je zaradi nagiba dvignjen od tal in tako seveda ne pride v stik s snegom. Na ta način dosežemo vožnjo, če jo primerjamo s klasično vožnjo, kot bi imeli dve različni smučki v eni sami vožnji. Tako izkoriščamo prednost dolgih smuči z večjo hitrostjo pri vožnji naravnost in uporabnost kratkih smuči pri vožnji v zavoju.The technical problem is solved according to the invention in such a way that the extended ski is made of the base part and the extension piece, which are inseparable from the manufacturing process and represent a solid whole. A ski extension has been added to the basic structural part of the ski, which is a suitable model for a snow ski. The ski extension has a smaller width than the base part of the ski. When riding straight, the base part of the ski and the ski extension evenly glide through the snow with the entire sliding surface. In the case of curves, which are characterized by running on curbs, in contact with the snow is only the basic part of the ski. The narrow extension of the ski is raised from the ground due to the slope and thus does not naturally come into contact with the snow. In this way, driving is compared to a classic ride, as if you had two different skis in a single ride. Thus, we take advantage of longer skis with faster speeds when driving straight and the utility of short skis when cornering.

Podaljšek smučke je lahko izveden na prednjem in zadnjem delu smučke. Z ožjim sprednjim podaljškom prav tako kot z zadnjim podaljškom dosežemo večje hitrosti zaradi ozkega in dolgega dela z manjšim uporom drsne ploskve. Pri zavijanju je sprednji podaljšek prav tako kot zadnji podaljšek dvignjen od tal in tako ne ovira ostrega zavijanja.The ski extension can be made on the front and back of the ski. With a narrower front extension, as with the rear extension, higher speeds are achieved due to the narrow and long section with less sliding surface resistance. When cornering, the front extension, just like the rear extension, is raised from the ground, thus not hindering sharp cornering.

S stališča uporabnikov je smučarska deska čisto nekaj drugega kot smučka. Tehnično gledano gre za enak izdelek, ki sledi istim fizikalnim zakonitostim le dimenzije so različne. Smučarska deska ima drugačna razmerje med širino in dolžino kot klasična smučka, pogoji smučanja pa ostajajo enaki. Bistvena razlika je pri uporabi smučarske deske kadar jo vozimo v obeh smereh. Smučarska deska, ki je namenjena za vožnjo naprej in nazaj mora imeti na obeh straneh dvignjen začetek oziroma konec. Smučarska deska, ki ima manjše razmerje med dolžino in širino, drugače ustreza pogojem izdelave podaljšane smučke. Zato smučarsko desko tehnično prištevamo v skupino podaljšana smučka in sicer kot podaljšana smučka z manjšim razmerjem med dolžino in širino.From a user standpoint, a ski board is something other than a ski. Technically speaking, it's the same product that follows the same physical laws, but the dimensions are different. The ski board has a different width to length ratio than a classic ski, and the ski conditions remain the same. The essential difference is when using a ski board when driving in both directions. The ski board intended for running back and forth must have a start or finish on both sides. The ski board, which has a smaller length-to-width ratio, otherwise meets the conditions for making an extended ski. That is why the ski board is technically classified as an extended ski as an extended ski with a smaller length to width ratio.

Podrobneje je bistvo izuma pojasnjeno v nadaljevanju z opisom izvedbenega primera in priloženi risbi, ki prikazuje sl. 1 shematski prikaz podaljšane smučkeThe essence of the invention is explained in more detail below with a description of an embodiment and the accompanying drawing showing FIG. 1 schematic illustration of an extended ski

Podaljšana smučka je izdelana iz osnovnega dela in podaljškov, ki predstavljajo neločljivo celoto.Osnovni del vsebuje konico smučke 4, drsno ploskev 5 in rep smučke 6. Rep smučke 6 je podaljšan z zadnjim podaljškom smučke 7. Zadnji podaljšek smučke 7 mora biti po širini ožji od repa smučke 6. Zadnji podaljšek smučke 7 ima konec zadnjega podaljška 8, ki je pretežno raven. Smučka mora spredaj odrivati sneg, zato je pri uporabi prednjega podaljška smučke 1 smiselna uporaba dvignjenega in zaobljenega začetka prednjega podaljška 2. Tehnologija izdelave smuči omogoča pri uporabi prednjega podaljška smučke 1, da je konica smučke 4 manjša, kar se odraža v manjši porabi materiala potrebnega za izdelavo smučke. Pri tem mora biti začetek konice 3 dvignjen prav tako kot dvignjeni začetek prednjega podaljškaThe extended ski is made of the base part and the extensions that form an integral whole.The base part contains the tip of the ski 4, the sliding surface 5 and the tail of the ski 6. The tail of the ski 6 is extended by the rear extension of the ski 7. The rear extension of the ski 7 should be narrower in width. from the tail of the ski 6. The last extension of the ski 7 has the end of the last extension 8, which is predominantly straight. The ski must be snow-fronted, so when using the front extension of ski 1 it makes sense to use the raised and rounded start of the front extension 2. The technology of ski construction allows the use of the front extension of ski 1 to reduce the tip of the ski 4, which is reflected in less material consumption. for making a ski. In doing so, the beginning of the tip 3 should be raised just like the beginning of the front extension

2.2.

Na prednjem podaljšku smučke 1 in zadnjem podaljšku smučke 7 ni primerna namestitev ostrih robnikov. Ob delnem stranskem stiku podaljškov smučke pri zavijanju na grbinah ne sme priti do prečnih sil, kar povzročajo ostri robniki.Sharp edges are not suitable on the front extension of the ski 1 and the rear extension of the ski 7. With partial lateral contact between the extensions of the ski, there should be no transverse forces when turning on the humps, which is caused by sharp edges.

Drugačna izvedba podaljšane smučke, ki ima manjše razmeije med dolžino in širino se s komercialnim imenom imenuje smučarska deska, vendar je tudi pri njej aktualna uporaba prednjega podaljška smučke 1 in zadnjega podaljška smučke 7.A different design of an extended ski, which has smaller length-to-width ratios, is known by the commercial name of the ski board, but it also applies to the front extension of the ski 1 and the rear extension of the ski 7.

Seveda je lahko zadnji podaljšek smučke 7 izveden tudi drugače, tako da je konec zadnjega podaljška 8 dvignjen in zaobljen, kar pride v poštev pri akrobatski smučarski deski.Of course, the rear extension of the ski 7 may also be made differently so that the end of the rear extension 8 is raised and rounded, which is the case with the acrobatic ski board.
