Tehnični problemA technical problem

Tehnični problem, ki ga rešuje izum je, kako zasnovati sklop smučarskega čevlja in varnostne vezi smučke za alpsko smučanje, ki bo odpravila problem vskladitve velikosti čevlja in njemu prilagojene varnostne vezi zlasti pri smučeh za izposojo, ne da bi popačil smuške lastnosti smučke, ki so bile načrtovane pri proizvajalcu smuči in zmanjšal torzij ske obremenitve v nogi smučarja pri padcu, pri čemer bo nova oblika čevlja ponovno sprostila možnost izdelave hoji prijaznega čevlja z odpravo togosti togosti podplata in iz tega izhajajočega mehkejšega nartnega dela lupine smučarskega čevlja.A technical problem solved by the invention is how to design a ski shoe assembly and a ski luggage safety harness that eliminates the problem of adjusting the shoe size and the safety lugs tailored to it, especially for rental skis without distorting the ski characteristics of the ski. were designed by the ski manufacturer and reduced the torsional load on the skier's leg in the fall, with the new shoe design again releasing the ability to make a walking-friendly shoe by eliminating the rigidity of the sole of the sole and the resulting softer part of the ski boot shell.

Znano stanje tehnikeThe prior art

Znani sklopi smučarskega čevlja in varnostne vezi smučke so praviloma izvedeni tako, da varnostna vez drži smučarski čevelj vpet spredaj med prsti in hkrati zadaj za peto. Oblika in dimenzija nastavkov na smučarskem čevlju je standardizirana zaradi zagotovitve kompatibilnosti čevljev in vezi različnih proizvajalcev.Known ski boot assemblies and ski safety ties are generally designed so that the safety shoe holds the ski shoe in front between the toes and at the same time behind the heel. The shape and dimension of the ski boot fittings are standardized to ensure the compatibility of the shoes and the ties of the various manufacturers.

Zaradi vpetja čevlja na konici in peti, je vez vsakokrat dimenzijsko prirejena izbrani velikosti čevlja. Glede na dejstvo, da se povečuje število smuči in čevljev za vsakodnevno izposojo, pa postane zmeraj večja potreba po takem sklopu čevlja in vezi, ki bo omogočal in zagotavljal brez kakršnihkoli prireditev sklopa oziroma vezi poljubni velikosti čevlja. Samo na tak način lahko izposojevalnica nudi neodvisno izbiro posebej smuči in čevljev.Due to the attachment of the shoe at the tip and the heel, the embroidery is in each dimension adapted to the shoe size selected. Due to the fact that the number of skis and shoes for daily rental is increasing, there is an ever greater need for such a shoe and shoe assembly that will allow and provide without any adjustments to the shoe and shoe size of any size. Only in this way can the borrower offer an independent choice of skis and shoes specifically.

Pri znanih rešitvah vezi in čevlja je potrebno vsakokratno prirejanje zeva okovja dolžini čevlja, kar zahteva nekaj časa in obenem podraži storitev. Obstajajo sicer vezi za hitro nastavljanje zeva, pri katerih je sicer to opravilo hitrejše, vendar brez ročne vsakokratne nastavitve vendarle ne gre.Known shoe and shoe solutions require tailoring the shoe length to the shoe length, which will take some time and at the same time become more expensive. Although there are links to quickly adjust the yawn, which may have done the job faster, but without manual manual adjustment, it still does not work.

Nadalje delujejo dosedanje konstrukcije vseh vezi slabšalno na karakteristiko smuči. Zaradi nujnega togega vpetja čevlja v vez pred prsti in za peto, je potrebno togo vpetje vezi na podlago. Če je vez nameščena neposredno na smučko, vpliva togost vpetja vezi na elastičnost srednjega dela smučke s popačenjem zveznosti loka smučke, ki je posledica njenega odziva na način vožnje in na podlago. Ker pa nikakor ne moremo odpraviti sicer za dobro smučanje popačenega krivljenja smučke v območju vezi, mora konstrukcija vezi vsebovati elemente, ki kompenzirajo premikanje vezi glede na podplat čevlja zaradi elastičnosti smučke. Sila vpetja čevlja v vez mora biti namreč nastavljiva v ozkem tolerančnem območju zaradi zagotovitve izpetja čevlja pri prekoračitvi nastavljene vrednosti obremenitve v različnih smereh glede na čevelj. Te zahteve pa pogojujejo bolj zamotano konstrukcijo vezi, kar pomeni tudi višjo ceno in večjo možnost okvare ali napačnega delovanja.Furthermore, the structures of all the ties made so far have a detrimental effect on the ski characteristics. The necessary rigid attachment of the shoe to the toe and heel requires a rigid attachment of the shoe to the base. If the binding is placed directly on the ski, the rigidity of the binding of the ski affects the elasticity of the middle part of the ski by distorting the continuity of the ski arc, which is the result of its response to the driving mode and the base. However, since we cannot in any way remedy the good skiing distortion of the ski in the bond area, the construction of the ties must contain elements that compensate for the movement of the ties with respect to the sole of the shoe due to the elasticity of the ski. The force of the shoe's attachment to the tie must be adjustable in a narrow tolerance range in order to ensure that the shoe is loosened when the set load value is exceeded in different directions relative to the shoe. These requirements, however, make the construction of the bundle more complicated, which also means a higher price and a greater chance of failure or malfunction.

Da bi odpravili nekaj gornjih pomanjkljivosti, so razviti vmesniki med smučko in vezjo. Vmesnik je elastično vpet na smučko, da omogoča praktično nemoteno delovanje smučke. Na vmesniku je togo vpeta vez, da zagotavlja pravilno inTo remedy some of the above shortcomings, interfaces between the ski and the circuit are developed. The interface is elastically mounted on the ski to allow the ski to run smoothly. There is a rigid connection on the interface to ensure correct and

27604.doc/VI-00/D23-Vr stalno enako silo vpetja čevlja v njej. Kot stranska posledica te rešitve je nezaželena povečana teža smučke in tudi povišana cena.27604.doc / VI-00 / D23-Vr The constant same force of engagement of the shoe in it. A side effect of this solution is the undesirable increased weight of the ski and also the increased cost.

Ni pa odpravljena vsakokratna nastavljivost zeva vezi velikosti čevlja.However, the adjustability of the shoe size ties is not eliminated.

Razume pa se tudi, da so vsi znani smučarski čevlji zaradi togosti podplata, kije posledica vpetja čevlja spredaj in zadaj, izrazito neprijazni za hojo. Vemo pa, da brez hoje vsaj na kratke razdalje v smučarskih čevljih le ne gre.However, it is also understood that all known ski boots, due to the rigidity of the sole, which is the result of the shoe's attachment to the front and rear, are extremely unfit for walking. However, we know that without walking at least a short distance in ski boots just does not go.

Zato obstaja potreba po udobnejših, tudi za hojo primernejših smučarskih čevljih ob ohranitvi ostalih lastnosti, ki so potrebne med smučanjem.Therefore, there is a need for more comfortable, even for walking, more appropriate ski boots while maintaining the other features that are required while skiing.

Rešitev tehničnega problemaThe solution to a technical problem

Opisani tehnični problem je rešen z novim sklopom smučarskega čevlja in varnostne vezi za alpsko smučanje po izumu, katerega bistvo je, da je na oziroma v podplatu smučarskega čevlja v navidezni osi noge oziroma golenice smučarja izveden sorazmerno kratek element, ki uprijemlje v zev vezi po izumu, pri čemer je dimenzija elementa v čevlju in s tem zeva v vezi konstantna, torej neodvisna od velikosti čevlja in je vez izvedena kot varnostna vez, ki ustreza predpisom oziroma standardom o varnostnih vezeh. Zaradi istih dimenzij uprijemnega elementa v čevlju ne glede na njegovo velikost, uprijemljejo vsi čevlji s tem elementom v katerikoli smuči brez predhodne nastavitve zeva.The described technical problem is solved with a new set of ski boots and safety ties for alpine skiing according to the invention, the essence of which is that a relatively short element is held on the sole of the ski shoe in the virtual axis of the ski or tibia of the skier, which fits into the yawn of the ties according to the invention. , whereby the dimension of the element in the shoe and thus the yawning in the ties is constant, ie independent of the size of the shoe, and the tie is made as a safety tie that meets the regulations or standards on safety ties. Due to the same dimensions of the gripping element in the shoe, regardless of its size, all shoes with this element in any ski can fit without any yawn pre-setting.

Ker je uprijemni element v podplatu čevlja sorazmerno kratek in ker le on uprijemlje v vez na smučki, je lahko preostali delo podplata čevlja, t.j. nartni del, izveden poljubno, da omogoča oblikovati za hojo primernejše obuvaloSince the gripping element in the sole of the shoe is relatively short, and since it solely grips the binding on the ski, the rest of the work may be the sole of the shoe, i.e. Optional workpiece, designed to make walking shoes more comfortable

27604.doc/VI-00/D23-Vr27604.doc / VI-00 / D23-Vr

Uprijemni element v čevlju ima na petnem koncu dodan element s konkavno konično polkrožno prijemalno ploskvijo, ki leži na njegovi spodnji strani in katere središče leži približno na osi noge oziroma golenice smučarja, medtem ko je na sprednjem delu izveden element z lokasto ploskvijo, katere središče sovpada s središčem navedene nasprotiležne polkrožne konične prijemalne ploskve in ki vsebuje vsaj eno, prednostno pa dve vdolbini, pri čemer je med to ploskvijo in spodnjo ravnino uprijemnega elementa izveden še dodaten žleb.A shoe element with a concave conical conical semicircular grasp at its lower end is added at the heel end, the center of which lies approximately on the axis of the skier's leg or tibia, while an element with an arched surface whose center coincides at the front. with the center of said opposite semicircular conical gripping surface and comprising at least one, preferably two recesses, an additional groove being formed between this surface and the lower plane of the gripping member.

Komplementarna varnostna vezje nameščena na smučki samo na enem mestu, da ne vpliva na karakteristiko smuči. Vez sestoji iz dveh, osno omejeno med seboj razmakljivih delov, od katerih je sprednji del fiksiran na smučko na sorazmerno majhnem polju, ki ne vpliva na karakteristiko smučke. Zadnji del vpet v sprednji del tako, daje osno omejeno premakljiv, medtem ko je v ostalih smereh voden v vodilih, izvedenih v sprednjem delu. Zadnji del vsebuje na petnem delu konveksno polkrožno konusno ploskev, ki prilega konkavni konični ploskvi na podplatnem uprijemnjem delu vezi, na sprednjem delu pa sta izvedena dva zasukljiva in s stopničasto čelno ploskvijo izvedeno dela, ki uprijemljeta v žleb na prednjem delu elementa vezi v podplatu in sta pozicionirana, s tem pa tudi čevelj glede na vez oziroma smučko s pomočjo vsaj ene izbokline oziroma komplementaren vbokline, ki sta oblikovani na priležnih ploskvah elementa na čevlju ter hkrati na stopničasti lokasti ploskvi vsaj enega zasukljivega dela. Zasukljiva dela nas prednjem delu vezi ter zadnji del z lokasto ploskvijo so nastavljivo elastično vzmeteni v podnožju vezi z namenom, da ob prekoračitvi nastavljene vrednosti, kije odvisna od predvidene največje dopustne sile na nogo smučarja v poljubni smeri, vzmet sprosti in dovoli trenutno izpenjanje čevlja iz vezi. Vez ima tudi vzvod, s katerim po potrebi ročno izpnemo čevelj.The complementary safety circuit is mounted on the ski in one place only so as not to affect the characteristics of the ski. The berth consists of two axially bounded apart parts, the front of which is fixed to the ski in a relatively small field which does not affect the ski characteristic. The rear part is mounted in the front part so that it is axially limited movable, while in other directions it is guided in guides made in the front part. The rear part comprises a convex semicircular conical surface on the fifth part, which fits into a concave conical surface on the sole upright part of the ligament, and two rotatable and stepwise face portions are made on the front, which adhere to a groove at the front of the element of the sole in the sole and they are positioned, and thus also the shoe with respect to the binding or the ski, by means of at least one projection or complementary recesses, which are formed on the adjacent surfaces of the element on the shoe and at the same time on the stepped arched surface of at least one rotatable part. The pivoting parts of the front part of the link and the rear part with the arched surface are adjustable elastically sprung at the base of the link in order to release the spring and allow instant shoe extension from the specified value, which depends on the predicted maximum permissible force on the skier's leg in any direction. ties. The embroidery also has a lever that can be used to manually unload the shoe.

The front part 4 of the base is intended for fixed mounting on the ski 2, while the rear part 5 is not fixed on the ski 2 and guided in the front part 4 so that it is limited in the axis of the ski.

Na prednjem delu 4 sta zasukljvo na isti osi 6 nameščena zasukljiva dela 7, ki sta predvidena za uprijem elementa 3 na podplatu A smučarskega čevlja. Na zadnjem delu 5 je izveden element 8 s polkrožno konusno oblikovano prijemalno zadnjo ploskvijo 9, ki uprijemlje v komplementarno oblikovani zadnji del uprijemnega elementa 3. Sprednji del 4 in element 8 zadnjega dela 5 sta povezana med seboj tako, da podkvasti del 8' elementa 8 zadnjega dela 5 delno z boka oklepa sprednji del 4 tako, da je s tem v osni smeri smuči tudi voden, pri čemer izboklini 10 na podkvastem delu 8’ ležita v daljših vboklinah 11 na sprednjem delu 4 in s tem določata osni pomik v vboklinah 11, posledično pa osni pomik celotnega zadnjega dela 5 glede na sprednji del 4.On the front part 4, rotatable parts 7 are provided on the same axis 6, which are intended to support the element 3 on the sole A of the ski boot. On the rear portion 5, an element 8 is formed with a semicircular conical shaped gripping rear surface 9 which adjoins the complementarily formed rear portion of the mounting element 3. The front portion 4 and the rear element 8 are connected to each other such that the horseshoe portion 8 'of the element 8 the rear part 5 partially encloses the front part 4 from the side so that it is also guided in the axial direction, with the projections 10 on the horseshoe part 8 'lying in the longer recesses 11 on the front part 4, thereby determining the axial displacement in the recesses 11 and consequently the axial displacement of the entire rear 5 relative to the front 4.

Na sprednjem delu 4 zasukljivo uležajena dela 7 sta med seboj povezana z vzmetjo 12, kiju drži razprta tako, da se nahajata v položaju za sprejem elementa 3 oziroma čevlja.On the front part 4, the pivotally mounted parts 7 are connected to each other by a spring 12 which is held open so that they are in the position of receiving the element 3 or the shoe.

Zadnji del 5 je podaljšan nazaj izza čevlja, kjer se nahaja ležišče 13 za napenjalnik 14, kije uležajen v ležišču 13 preko vzvodov 15, ki omogočata ročenThe rear part 5 is extended back from behind the shoe housing the tensioner bearing 13, which is restrained in the bearing 13 via levers 15 which enable

Napenjalnik 14 je s svojim drogom 16, ki je glede na ohišje 17 napenjalnika uležajen v vzmeti 15, kije nastavljivo prednapeta z vijakom 18, povezan preko vzdolžno potekajočega traku 19 z zasukljivima deloma 7 s svojim trikotno ošiljenim sprednjim koncem 20. Trak 19 je prednostno uležajen osno pomično v žlebu 21, kije izveden tako v prednjem delu 4, kot v zadnjem delu 5.The tensioner 14 is connected with its rod 16, which, with respect to the housing 17 of the tensioner, is mounted in a spring 15 which is adjustably biased by a screw 18, connected via a longitudinally extending strip 19 to the rotatable parts 7 with its triangularly angled front end 20. The strip 19 is preferably mounted axially movable groove 21, which is made both in the front part 4 and in the rear part 5.

Na zadnjem delu 5 je nad trakom 19 izveden most 22 in na njem že navedeni element 8 s polkrožno konusno ploskvijo 9, ki uprijemlje v komplementarno oblikovani zadnji del uprijemnega elementa 3 v podplatu A čevlja.On the rear part 5, a bridge 22 is made above the strip 19 and the element 8 already mentioned thereon, with a semicircular conical surface 9, which holds into the complementarily formed rear part of the upright element 3 in the sole A of the shoe.

V prednjem delu 4 je pod trakom 19 izveden osno vzmetno podprt zastopničen čep 23, ki uprijemlje v podolgovato luknjo 24 v traku 19, pri čemer je stena luknje 24 zastopničena komplementarno čepu 23.In the front portion 4, an axially spring-supported representative pin 23 is made under the strip 19, which is supported by an elongated hole 24 in the strip 19, with the wall of the hole 24 being complementary to the pin 23.

Zasukljiva dela 7 sta na čelni strani izvedena z naprej in iznad njune ravnine ležečima zoboma 25, pri čemer sta na čelni strani delov 7 pod zoboma 25 oblikovani pozicionimi izboklini 26.The rotatable parts 7 are formed on the front side with teeth forward and above their plane 25, with positioning projections 26 formed on the front side of the parts 7 below the teeth 25.

Zasukljiva dela 7 sta prekrita s ploščo 27, na kateri leži čevelj s svojim sprednjim delom.The rotatable parts 7 are covered with a plate 27 on which the shoe with its front part rests.

Na vezi je lahko integralno izvedena znana zavora, katero je sicer možno izvesti tudi ločeno. Zavora ni prikazana na risbah.A known brake can be integrated integrally, which can be performed separately. The brake is not shown in the drawings.

Uprijemni element 3, ki je vgrajen v podplatu A smučarskega čevlja, je izveden kot podolgovata plošča, ki ima na sprednjem delu na strani prileganja vezi 1The mounting element 3, which is embedded in the sole of the ski boot A, is designed as an elongated plate having a front at the side of the fit of the ties 1

Na ploskvi 29 sta izvedeni vboklini 32. Lokasta ploskev 29, vboklini 32 na njej in utor 31 so komplementarno oblikovani glede na čelni del zobov 25 in pozicionimi izboklini 26 zasukljivih delov 7 tako, da zobova 25 vprijemljeta v utor 31, izboklini 26 pa v vboklini 32.27604.doc / VI-00 / D23-Vr a convex part 28 with an arched surface 29 on the inner side, passing the surface 29 into the lower surface 30 of the element 3 via an arched groove 31. The surface 29 shows the recesses 32. The arched surface 29, the recesses 32 thereon and the groove 31 are complementarily formed with respect to the frontal portion of the teeth 25 and the positional projections 26 of the rotatable parts 7 so that the teeth 25 engage in the groove 31 and the projections 26 in the recess 32.

Na zadnjem delu je uprijemni element 3 na strani prileganja vezi 1 izveden z izbočenim delom 33, katerega notranja ploskev 34 je konusna in konkavno lokasta ter komplementarna ploskvi 9 elementa 8 vezi 1.At the rear, the gripping element 3 on the fitting side of bond 1 is made with a convex part 33, the inner surface 34 of which is conical and concave, and complementary to the surface 9 of element 8 of bond 1.

Element 3 je v podplatu tako izveden tako, da ne ovira pri hoji. Zaradi sorazmerne manjhne dolžine elementa 3 v podplatu je celoten nartni del čevlja neobremenjen s silami vpetja v vez, zato je lahko prožen. Samo manšeta in del školjke, kjer sta spojena ta dva dela, morata biti tako toga, da nudita oporo gležnju. S tem je dosežen pogoj za mehkejši čevelj v nartnem delu, ki olajšuje hojo, togost čevlja v gležnju pa ohranja potrebne karakteristike čevlja pri smučanju.Element 3 is so constructed in the sole that it does not obstruct walking. Due to the relatively small length of the sole 3 in the sole, the entire boot portion of the shoe is unburdened by the forces of engagement, so it can be flexible. Only the cuff and the part of the shell where the two parts are joined must be rigid enough to support the ankle. This creates the condition for a softer shoe in the work area that facilitates walking, and the rigidity of the ankle shoe maintains the necessary shoe characteristics when skiing.

Vpenjanje čevlja v vez se izvede tako, da ročno razbremenimo vzmet 15 v napenjalniku 14 tako, da ga dvignemo, s čimer se pomakne nazaj. Vzmetno podprt čep 23 zaskoči v podolgovati luknji 24 v traku s svojim širšim delom in fiksira trak 19 v zadnji legi, s čimer se postavita zasukljiva dela 7 zaradi vzmeti 12 v medsebojno priležno lego. Nato ponovno napnemo napenjalnik 10 s potiskom v spodnjo lego. V praksi je ta faza že izvedena pri predhodnem izpenjanju čevlja. S petnim delom čevlja se približamo poševni konični ploskvi 9 na vezi 1 ob dejstvu, daje napenjalnik 10 ročno predhodno napet. Dela 5 sta v svoji zadnji legi, ker je trak 19 fiksiran v zadnji napeti legi s čepom 23. Nato priležemo prednji del podplata čevlja na vez 1, da se ujame izbočeni del 28Clamping the shoe into the tie is done by manually releasing the spring 15 in the tensioner 14 by lifting it, thereby moving it backwards. The spring-supported plug 23 snaps into the elongated hole 24 in the strap with its wider part and locks the strap 19 in the rear position, thereby placing the swivel parts 7 due to the spring 12 in a mutually adjacent position. Then re-tighten the tensioner 10 by pushing it to the lower position. In practice, this stage has already been carried out in the pre-straining of the shoe. With the heel portion of the shoe, we approach the oblique tapered surface 9 at the tie 1 due to the fact that the tensioner 10 is manually pre-tensioned. Parts 5 are in their rear position because the strap 19 is fixed in the rear tense position with a stud 23. Then we attach the front of the sole of the shoe to the tie 1 to catch the protruding portion 28

At the same time, the sole A of the shoe pushes the stud 23 into the lower position, thereby releasing the strap 19 to jump forward due to the tense spring 15, unlocking the rotating parts 7, which with its teeth 25 snap into the groove 31 of the part 3, the projections 26 however, they are positioned in recesses 32 of part 3. At the same time that the strap 19 opens the rotatable parts 7 and snaps into part 3, the force of the spring 15 pushes the entire rear part 5 back to create a force connection between part 3 and the ties 1. When the load is exceeded per shoe in accordance with standards, the spring is released to unlock first at the front or rear according to the direction of action of the external force.
