Abstract

The training aid for alpine skiing on snow-free slopes provides the possibility of practising alpine skiing, particularly slalom and giant slalom with a very similar technique to the skiing technique so that the training with this equipment does not represent any inconvenience to move from "preliminary" training to practising on natural snow. The aid is made from a profile (1) featuring two supports (3, 4) looking at opposite sides in front and in the back while on each leg (6, 7) of the supports (3, 4) there is at least one wheel (5) so that the axes (8) of the wheels (5) are at level and that the leg (6, 7) wheel (5) axes (8) of one support (3 or 4) are at an angle (alpha) open towards the centre of the profile (1) or the wheels (5) are on the same side of the profile (1) tangentially on the virtual arch (L). The legs (6, 7) of each support (3, 4) are connected to each other by a distancing mechanism (9) for adjusting the (alpha) angle.

Description

PRIPOMOČEK ZA VADBO ALPSKEGA SMUČANJA NA NEZASNEŽENIH STRMINAHACCESSORY FOR TRAINING ALPINE SKIING ON NON-SNOW SANDS

Področje izumaFIELD OF THE INVENTION

Predmet izuma je pripomoček za vadbo alpskega smučanja na nezasneženih strminah, npr. cestnih klancih.The subject of the invention is a device for training alpine skiing on snow-covered slopes, e.g. road slopes.

Tehnični problemA technical problem

Tehnični problem, ki ga rešuje izum je, kako izvesti tak pripomoček za vadbo alpskega smučanja na nezasneženih strminah, ki bo omogočal simulacijo tehnike alpskega smučanja.The technical problem solved by the invention is how to perform such a device for training alpine skiing on snow-covered slopes, which will allow simulation of the technique of alpine skiing.

Znano stanje tehnikeThe prior art

Znani so tovrstni pripomočki, ki so nameščeni pod obuvalom, običajno kar čevljem za alpsko smučanje in so izvedeni kot kratka smučka, ki ima pod spodnjo, t.j. drsno ploskvijo nameščen neskončni narabričeni trak, gosenico, ki je vpet na vzmetenih ležajih, da omogoča vadbo smučanja tudi po neravnem pobočju. Namenjen je za vadbo po zatravljenih pobočjih, prednostno kopnih smučarskih progah za poletni suhi trening. Pomanjkljivost tega pripomočka je, da tvori gosenica ravna stranska robova, medtem ko sta pri smučkah stranska robova izvedena v loku, pri čemer jeSuch accessories are known to be fitted under the shoe, typically as alpine ski boots, and are designed as a short ski having a downstairs, i.e. An infinitely pleated ribbon is mounted on the sliding surface, a track mounted on suspension bearings to allow skiing to be practiced even on uneven slopes. It is intended for training on grassed slopes, preferably inland ski runs for summer dry training. The disadvantage of this accessory is that the caterpillar forms straight lateral edges, while in the case of skis the lateral edges are made in an arc, with

trend po zmeraj manjšem polmeru tega loka oziroma po poudarjenem loku, ki je sestavljen iz več zvezno med seboj povezanih krivulj. Zaradi te neskladnosti je občutek pri vadbi s takim pripomočkom tako različen od občutkov pri smučanju s sodobnimi smučmi, da jih pri vadbi za tekmovalne namene že škodljivo popači. Pokazalo se je namreč, da drugačna tehnika smučanja s tem pripomočkom kvarno spremeni precizno tehniko dejanskega smučanja. Prehod s suhega treninga na vadbo na snegu zahteva najprej vadbo za povrnitev na pravilno tehniko in šele nato sledi nadgradnja. Zato se ta pripomoček uporablja predvsem za zabavne in sprostitvene namene.a trend along the ever smaller radius of this arc, or along a pronounced arc that consists of several interconnected curves. Due to this inconsistency, the feeling when exercising with such a device is so different from the sensations when skiing with modern skis that it already distorts them when training for competitive purposes. Namely, it has been shown that a different technique of skiing with this device defectively alters the precise technique of actual skiing. The transition from dry training to a workout in the snow requires first a workout to return to the correct technique and only then an upgrade. Therefore, this gadget is used primarily for entertainment and relaxation purposes.

Nadalje je znan pripomoček, ki je namenjen za vadbo smučarskega teka. Izveden je kot krajša smučka z enim kolesom spredaj in enim ali dvema kolesoma na isti osi zadaj. Zadnje kolo ali par koles je uležajen z enosmerno drsno sklopko, ki simulira trenje med smučko in snegom. Tudi ta pripomoček ima isto pomanjkljivost kot že prvo opisani. Ne omogoča specialne vadbe pravilnega nagibanja nog in trupa v zavojih glede na stranski lok smučke, kar je ena bistvenih značilnosti tehnike alpskega smučanja.Furthermore, a device intended for the practice of cross-country skiing is known. It is designed as a shorter ski with one wheel in front and one or two wheels on the same axis at the rear. The rear wheel or pair of wheels is fitted with a one-way sliding clutch that simulates the friction between ski and snow. Also, this gadget has the same disadvantage as previously described. It does not allow special training of the proper tilting of the legs and torso in turns with respect to the lateral arch of the ski, which is one of the essential features of the Alpine skiing technique.

Glede na sodobni trend oblikovanja smuči z zmeraj manjšim polmerom stranskih lokov se spreminja tudi tehnika alpskega smučanja. Dosedanji pripomočki so zato še manj primerni, saj se tehnika vožnje z znanimi pripomočki zmeraj bolj oddaljuje od sodobne tehnike alpskega smučanja z novimi smučmi.Due to the current trend of ski design with the ever smaller radius of the side arches, the technique of alpine skiing is also changing. The current accessories are therefore even less suitable, since the technique of riding with known accessories is always further away from the modern technique of alpine skiing with new skis.

Iz tega izhaja močna potreba po novem pripomočku, pri katerem bodo odpravljene opisane pomanjkljivosti.This implies a strong need for a new device that will address the shortcomings described.

Rešitev tehničnega problemaThe solution to a technical problem

Opisani tehnični problem je rešen s pripomočkom po izumu tako, da je izveden kot podolgovat profil z okovjem za pritrditev obuvala na zgornjem srednjem delu. Bistvena novost rešitve je v tem, da sta na sprednjem in zadnjem koncu uležajena para koles, katerih vsakokratna os je lomljena v topem kotu in sicer tako, da ležita sprednje in zadnje kolo, ki sta nameščena na isti strani profila, tangencialno na isto krožnico. Na ta način simulirata kolesi, ki sta nameščeni na isti strani profila, stranska loka smučke, da je pri zavijanju možno uporabljati pravilno smučarsko tehnikoThe technical problem described is solved by the device according to the invention by being designed as an elongated profile with a shoe mounting device at the upper middle part. The essential novelty of the solution is that at the front and rear ends are mounted pairs of wheels, each axle being broken in a warm angle, such that the front and rear wheels, which are located on the same side of the profile, tangentially to the same circle. In this way, the wheels, which are mounted on the same side of the profile, simulate the lateral arch of the ski so that the correct skiing technique can be used when cornering.

nagiba telesa in razbremenitve zunanje in notranje smučke. Pripomoček po izumu nudi tak občutek vadečemu, ki je bistveno podoben občutku pri smučanju. Zato prehod z vadbe s tem pripomočkom na dejansko smučanje na snegu ne pogojuje posebne prilagoditve, oziroma popravka tehnike smučanja.tilts the body and relieves the outer and inner skis. The device according to the invention provides such a feeling of exercise that is substantially similar to that of skiing. Therefore, the transition from training with this device to actual skiing in the snow does not necessitate a specific adjustment or correction of the skiing technique.

Nadalje je možno izvesti pripomoček po izumu tako, da nastavljamo polmer krožnic, na katerih ležita levi oziroma desni kolesi. S tem se še bolj približamo tipom smučk za slalom ali veleslalom, oziroma smuk, ki se razlikujejo tudi po velikosti stranskega loka.Further, it is possible to make the device according to the invention by adjusting the radius of the circles on which the left or right wheels lie. This brings us even closer to the types of slalom or giant slalom or ski, which also differ in the size of the side arch.

Kotno postavljena kolesa povzročajo sicer neljubo drsenje (radiranje) pri vožnji naravnost, ko vozimo po vseh štirih kolesih, kar zmanjšuje hitrost vožnje in poveča obrabo kotalne površine koles. Vendar stremimo pri smučanju po čim pogostejšem zavijanju. Želimo in dejansko prehajamo zvezno z enega zavoja v drugega, tako, da je odsekov smučanja naravnost zelo malo glede na celotno progo. Eanko tudi vadimo s pripomočkom po izumu tako, da čim preje prehajamo iz enega zavoja v drugega. V praksi vozimo po vseh štirih kolesih samo kratek čas med prehodom iz enega zavoja v drugega. Če pa želimo vaditi smuk, pri katerem pričakujemo dudi daljše odseke vožnje naravnost, pa že zaradi prireditve stranskega loka pri pripomočku po izumu stranskemu loku z velikim polmerom smučke za smuk, zelo zmanjšamo ta neugodni učinek.Angularly positioned wheels cause otherwise unsteady gliding (radiating) when riding straight when riding on all four wheels, which reduces the speed of travel and increases the wear on the rolling surface of the wheels. However, we strive to ski as often as possible when skiing. We want to, and indeed do, cross fed from one turn to another, so there are very few ski sections straight across the entire course. We also practice Eanko with the device according to the invention by passing as quickly as possible from one bend to another. In practice, we ride on all four wheels only a short time between the turns from one turn to another. However, if we want to practice skiing, which is expected to give long stretches of driving straight, because of the lateral arc arrangement of the device according to the invention, the lateral arc with a large radius of the ski ski will greatly reduce this adverse effect.

Razpiranje para koles na sprednjem ali zadnjem delu pripomočka je izvedeno z razpiralnim sredstvom, ki je prednostno kar dvojni vijak. Pri enostavnejših, oziroma cenejših izvedbah je to sredstvo klinast element, ki je nameščen med sprednjima oziroma zadnjima kolesoma. Pri najcenejši izvedbi pa so kolesa nameščena fiksno, da ležijo na predvideni krožnici, ki predstavlja stranski lok smučke.The wheel pair is opened at the front or rear of the accessory by means of a spreading means, preferably a double screw. In the case of simpler or less expensive embodiments, this means is a wedge element which is mounted between the front or rear wheels. In the cheapest version, the wheels are mounted fixedly on the intended circle, which represents the lateral arch of the ski.

Podrobneje bo bistvo izuma pojasnjeno v nadaljevanju z opisom izvedbenega primera in priložene risbe, na kateri kaže sl. 1 tloris pripomočka po izumu, sl. 2 stranski pogled istega.The essence of the invention will be explained in more detail below with a description of an embodiment and the accompanying drawing, in which FIG. 1 is a plan view of the device according to the invention; 2 side view of the same.

Pripomoček za vadbo alpskega smučanja na nezasneženih strminah je izveden iz profila 1, na katerem je nameščeno poljubno okovje 2, prednostno običajnoA device for training alpine skiing on snow-covered slopes is derived from profile 1, on which is mounted any fittings 2, preferably conventional

smučarsko, ki je prirejeno za smučarski čevelj, ki ni prikazan na slikah. Na sprednjem in zadnjem delu profila 1 sta izvedena naprej oziroma nazaj štrleča viličasta nosilca 3, 4 koles 5. Na vsakem kraku 6, 7 nosilcev 3, 4 je nameščeno po eno kolo 5 tako, da ležijo njihove osi 8 v eni ravnini. Kraka 6 in 7 vsakega nosilca 3, 4 sta med seboj povezana z nastavljivim razpiralnim sredstvom 9, prednostno dvojnim vijakom. Z razpiranjem krakov 6, 7 nastavljamo kot a, ki ga tvorita osi 8 para koles 5 na sprednjem oziroma zadnjem delu profila 1, pri čemer razumemo kot a tisti topi kot, ki je odprt proti središču profila 1. S tem seveda spreminjamo polmer R loka L, na katerem ležita tangencialno sprednje in zadnje kolo 5 na isti strani profila 1. S tem simulirata stranska loka smučke.a ski that is adapted for a ski boot not shown in the pictures. The front and rear sections of profile 1 have fork or fork projections 3, 4 wheels 5 projecting respectively. On each arm 6, 7 of the supports 3, 4 one wheel 5 is positioned so that their axes 8 lie in one plane. The arms 6 and 7 of each carrier 3, 4 are interconnected by an adjustable spreading means 9, preferably a double screw. By expanding the legs 6, 7, we adjust the angle a formed by the axes 8 of a pair of wheels 5 at the front or rear of profile 1, which is understood as a the blunt angle that is open toward the center of profile 1. This naturally changes the radius R of the arc L, on which tangentially the front and rear wheels 5 lie on the same side of profile 1. This simulates the lateral arcs of the ski.

V poenostavljeni različici sta kraka 6 in 7 nosilcev 3, 4 izvedena razprto, da tvorita določen kot a, pri čemer so kolesa 5 nameščna na krakih 6 in 7 enako kot pri zgorja opisani različici.In the simplified version, the arms 6 and 7 of the supports 3, 4 are made open to form a certain angle a, whereby the wheels 5 are mounted on the arms 6 and 7 in the same manner as in the version described above.

Kolesa 5 imajo prednostno polkrožni presek tekalne površine 10. S tem nalega vsako kolo 5 vedno in ne glede na velikost kota a, oziroma nagib pripomočka na eno ali drugo stran, s sorazmerno majno površino na podlago, da se zmanjša vpliv drsenja tekalne površine koles 5 po podlagi pri vožnji naravnost zaradi neskladja odklona koles 5 (kot a) in smeri vožnje na njihovo obrabo in zmanjšanje hitrosti.The wheels 5 preferably have a semicircular cross-section of the running surface 10. In this way, each wheel 5 always and irrespective of the size of the angle a, or the inclination of the accessory on one side or the other, with a relatively small surface on the base, to reduce the impact of the running surface of the wheels 5 after running straight due to the discrepancy between the wheels 5 (angle a) and the direction of travel on their wear and speed reduction.

S pripomočkom po izumu vadimo alpsko smučanje po nezasneženih strminah, prednosto cestnih klancih ipd., tako da vozimo naravnost po vseh štirih kolesih, medtemo ko v zavojih nagnemo pripomoček z isto tehniko kot pri alpskem smučanju, tako da vozimo samo po dveh kolesih z iste strani pripomočka. V tem primeru se pripomoček odziva na enak način kot alpska smučka. Z nastavljanjem kota a dodatno spreminjamo značilnost pripomočka, da natančno simuliramo alpsko smučko za slalom, veleslalom ali smuk.The device according to the invention trains alpine skiing on snow-free slopes, the advantage of road slopes, etc., by driving straight on all four wheels, but when turning the device in the same technique as in alpine skiing, so that only two wheels on the same side can be driven. gadget. In this case, the device responds in the same way as an alpine ski. By adjusting the angle a, we further modify the feature of the accessory to accurately simulate an alpine ski for a slalom, a giant slalom or a ski.

Dodaten vpliv in spremembo dosežemo z izborom materiala tekalnega obroča koles z ozirom na podlago, npr. beton, asfalt ipd., s čimer spreminjamo trenje med kolesi in podlago. S tem priredimo stopnjo oddrsavanja zadnjih koles v smislu oddrsavanja repov smuči.Additional impact and change is achieved by choosing the material of the wheel tread with respect to the ground, e.g. concrete, asphalt, etc., thereby changing the friction between the wheels and the base. This adjusts the degree of rear wheel slippage in terms of skis.

Predmet izuma je izdelan z običajnimi tehnološkimi postopki in ni potrebno posebno znanje. Predvideno je, da se uporabljajo znana kolesa za enovrstne kotalke, ki jihThe object of the invention is manufactured by conventional technological procedures and does not require special knowledge. It is envisaged to use known wheels for single-row rollers which

25626/D18-VII-97.Vr.25626 / D18-VII-97.

lahko dobimo na tržišču po primerni ceni in kvaliteti. Ker je predvidena podlaga za te kotalke ista kot za pripomoček po izumu, v celoti ustreza pester izbor materialov za kotalne obroče koles za te kotalke tudi pripomočku po izumu.can be obtained in the market at reasonable price and quality. Since the provided base for these rollers is the same as for the device according to the invention, it is entirely appropriate to have a varied selection of materials for the wheel rims for these rollers, also to the device according to the invention.

Razume se, da lahko strokvnjak s poznavanjem opisanega izvedbenega primera izvede tudi drugačne izvedenke pripomočka po izumu, zlasti viličastih nosilcev koles in razpiralnega sredstva, ter oblike profila, ne da bi se bistveno oddaljil od bistva izuma, kije opredeljeno v priloženih patentnih zahtevkih.It will be appreciated that one of skill in the art will be able to carry out other embodiments of the accessory according to the invention, in particular the fork-lifting wheel and spreader, and the shape of the profile without departing significantly from the spirit of the invention as defined in the appended claims.
