Description

STOPALNA VARNOSTNA VEZ S ČEVLJEM Z NASTAVLJIVIM STRANSKIM NAKLONOM ZA TEK NA SMUČEHFOOT SAFETY SHOE WITH ADJUSTABLE SIDE SLOPS FOR SKIING

Predmet izuma je stopalna varnostna vez s čevljem z nastavljivim stranskim naklonom za tek na smučeh. Izum spada v razred A 43 B 05/04 mednarodne patentne klasifikacije.The subject of the invention is a foot safety tie with a shoe with adjustable lateral inclination for cross-country skiing. The invention belongs to Class A 43 B 05/04 of the International Patent Classification.

Tehnični problem, ki ga predloženi izum uspešno rešuje je, kako 15 zagotoviti čim boljši odriv pri teku na smučeh ter čim boljšo stransko stabilnost pri odrivu. Nadalje je tehnični problem razširjen tudi na izdelavo čevlja za tek na smučeh, pri katerem bo nastavljiv stranski naklon. Tretji tehnični problem, ki ga uspešno rešuje izum je, kako zagotoviti varnost vezi, da bo pri prevelikih obremenitvah ob padcu vez spustila in se bo zato zmanjšala možnost poškodb ob padcu.A technical problem successfully solved by the present invention is how to provide the best possible cross-country treadmill and the best lateral stability in the cross-country. Furthermore, the technical problem extends to the manufacture of cross-country ski boots with a lateral inclination. A third technical problem that is successfully solved by the invention is how to ensure the security of the ties so that, in the event of excessive stresses, the ties will be released in the event of a fall, and thus the possibility of fall injuries will be reduced.

Vse znane konstrukcije vezi za tek na smučeh, ki so trenutno komercialno dostopne, imajo točko vpetja čevlja locirano na konici čevlja.All known ski cross-linking structures currently commercially available have a shoe clamping point located at the tip of the shoe.

Starejše izvedbe so imele na sprednji strani naprej podaljšan podplat, ki je služil za vpetje čevlja. Podaljšani del je bil fleksibilen, ker je bilo tako omogočeno dvigovanje petnega dela čevlja, kar je potrebno za lažji tek na smučeh. Te izvedbe so imele več problemov. Naprej podaljšani del podplata ni bil dovolj pregiben, posledica česar je bilo otežkočeno dvigovanje pete pri teku na smučeh. Podaljšani del podplata je bil zaradi neprestanega pregibanja tudi zelo obremenjen in je zato na pregibih material pokal.Older versions had a lengthened outsole on the front that used to secure the shoe. The elongated part was flexible because it allowed lifting the heel of the shoe, which is necessary for easier cross-country skiing. These implementations had several problems. The lengthened part of the sole was not sufficiently folded, which made it difficult to lift the heel while cross-country skiing. The lengthened part of the sole, due to the continuous folding, was also very burdensome and therefore the material of the cups was folded.

Naslednja generacija čevljev za tek na smučeh ima namesto spredaj podaljšanega podplata pod palcem na podplat čevlja pritrjeno osovino, katero zagrabi vez na tekaški smučki, ko je čevelj vpet. Osovina je vzporedna s podplatom čevlja in zgornjo ploskvijo smučke in je postavljena tako, da se okrog nje čevelj vrti v vzdolžni smeri glede na smučko.The next generation of cross-country ski boots have an axle attached to the shoe sole instead of the front lengthened sole, which catches on the cross-country ski when the shoe is engaged. The axle is parallel to the sole of the shoe and the upper surface of the ski and is positioned such that the shoe rotates about longitudinally with respect to the ski.

Posebej pri drsalni tehniki smučarskega teka je zelo pomembna stranska stabilnost smučarskega čevlja v fazi drsanja, ko čevelj s celim podplatom nalega na vez in v fazi odriva, ko se petni del čevlja dvigne. Ta problem so do sedaj reševali tako, da je bil podplat čevlja iz trdih materialov, zaradi česar je bilo zmanjšano vzdolžno torzijsko zvijanje čevlja in izboljšana stranska stabilnost, slaba posledica tega pa je, da se je čevelj v prstnem sklepu težko pregibal, pregibanje pa je potrebno za naraven tek. Nekateri proizvajalci so problem vzdolžnega torzijskega zvijanja poskušali odpravili z dodatno osovino, ki je locirana v podplatu čevlja za prvo, kar je sicer delno zmanjšalo vzdolžno torzijsko zvijanje čevlja, vendar je os vrtenja pri dvigovanju pete ob odrivu ostala na istem mestu, to je na sprednjem delu podplata pod palcem.Particularly important in skating technique is the lateral stability of the ski boot during the skating phase, when the shoe with the whole sole rests on the berth and in the tear-off phase when the heel of the shoe is lifted. So far, this problem has been solved so that the sole of the shoe was made of hard materials, which reduced the longitudinal torsional twisting of the shoe and improved lateral stability, a bad consequence being that the shoe in the toe joint was difficult to bend and the flexion was necessary for natural running. Some manufacturers have tried to eliminate the problem of longitudinal torsional twisting with an additional axle located in the sole of the shoe for the first, which partially reduced the longitudinal torsional twisting of the shoe, but the axis of rotation in lifting the heel when detached remained in the same place, that is in the front part of the sole below the thumb.

Druga slabost vezi z vpetjem spredaj se pokaže v fazi odriva pri teku na smučeh. Obe tehniki teka na smučeh, drsalna in diagonalna, sta sestavljeni iz dveh faz, faza drsenja in faza odriva. Fazi odriva na eni nogi sledi najprej faza drsenja na drugi nogi, ki preide v fazo odriva na drugi nogi in nazaj na prvo nogo, najprej drsenje nato odriv. Faza odriva je sestavljena iz dveh delov. V prvem delu odriva nalega podplat po celotni dolžini na tekaško vez in v tem delu točka vpetja ni pomembna. V drugem delu odriva pa se petni del čevlja dvigne in čevelj se zavrti okrog osi vpetja na sprednjem delu čevlja. V tej fazi se tekač na smučeh odriva od prstov in ne od točke na delu stopala, kjer je metatarzofalangealni sklep, kjer je odriv najbolj intenziven. Zaradi tega je odriv manj eksploziven.Another disadvantage of the front linkage is that it is evident in the phase of the skis when running. Both cross-country skiing techniques, skating and diagonal, consist of two phases, the skating phase and the slip phase. The stripping phase on one leg is followed first by the sliding phase on the other leg, which passes into the stripping phase on the other leg and back to the first leg, first the sliding then the ripping. The weaning phase consists of two parts. In the first part, it abuts the sole over the entire length of the treadmill and in this part the point of attachment is not important. In the second part of the tear off, the heel portion of the shoe rises and the shoe rotates about the pivot axis at the front of the shoe. At this stage, the skier runs away from the toes and not from the point on the part of the foot where the metatarsophalangeal joint is where the tearing is most intense. This makes the ebb less explosive.

Rešitev zgoraj prikazanih problemov je opisana v patentu US5664797, kjer je točka vpetja čevlja pomaknjena nazaj, pod stopalo. Problem te rešitve je v tem, da je skoraj onemogočeno dvigovanje zadnjega dela čevlja v zadnji fazi odriva, ko se petni del čevlja dvigne. Zadnji del čevlja se lahko dvigne le toliko, kolikor se čevelj ukrivi od točke vpetja nazaj.The solution to the problems shown above is described in US5664797, where the shoe clamping point is moved back, below the foot. The problem with this solution is that it is almost impossible to lift the back of the shoe in the last phase of the tear off when the heel of the shoe is lifted. The back of the shoe can only be lifted as far as the shoe curves from the point of retraction.

Fleksor, ki je lociran naprej od točke vpetja, se tudi stisne, vendar je zaradi prenizke točke vpetja to še vedno premalo za normalen tek na smučeh.The flexor, which is located forward of the clamping point, also compresses, but due to the low clamping point, this is still not enough for normal cross-country skiing.

Druga rešitev je opisana v patentu WO 0010413, kjer je točka vpetja prav tako pomaknjena nazaj. Da je omogočen zadosten dvig pete v zadnjem delu odriva, je čevelj, opisan v tem patentu, od točke vpetja naprej ukrivljen navzgor vsaj za 30°. Zaradi tega se čevelj zadaj lahko dvigne, je pa zaradi tega čevelj za tek anatomsko popolnoma neprimeren. Druga slabost te izvedbe je v tem, da zahteva nepregiben podplat čevlja, kar za tek tudi ni primerno.Another solution is described in patent WO 0010413, where the clamping point is also moved backwards. In order to allow sufficient lifting of the heel in the rear of the weft, the shoe described in this patent is bent upwards by at least 30 ° from the point of engagement. As a result, the boot can be lifted from the rear, but makes the shoe completely anatomically inappropriate. Another disadvantage of this design is that it requires a firm shoe sole, which is also not appropriate for running.

Nobena od komercialno dosegljivih in uporabljanih vezi za tek na smučeh ni varnostna, kar pomeni, da ob hudi obremenitvi ne popusti. V primerjavi z alpskim smučanjem se pri teku na smučeh dosegajo nižje hitrosti, pa tudi čevelj je v eni dimenziji glede na smučko prost, ker se vrti io okrog osi vpetja, tako da pri teku na smučeh ni tako velike potrebe po varnostni vezi. Ob hujših padcih pa vendar lahko pride do poškodb tekača ali zloma smučke, ker obstoječe vezi v nobenem primeru ne spustijo, razen ko jo ročno odpremo.None of the commercially available and used cross-country skiing bindings are safety, which means they do not loosen under heavy load. Compared to alpine skiing, lower speeds are achieved in cross-country skiing, and the shoe is free in one dimension, because it rotates io around the mounting axis, so there is not so much need for a safety connection when cross-country skiing. However, severe falls can result in damage to the runner or breakage of the ski, since the existing ligaments will in any case not be released except when manually opened.

Za drsalno tehniko teka na smučeh je ugodno, da podplat čevlja ni 15 vzporeden z zgornjo ploskvijo smučke, ampak da je nagnjen navzven, to pomeni, da tekač ob pokončni stoji stoji na o. Prednost nagnjenosti podplata pride do izraza v fazi odriva. Smučko je potrebno postaviti na notranji rob, da smučka pri odrivu ne zdrsne v stran. To tekač doseže tako, da koleno potisne navznoter. Zaradi nagnjenosti podplata je smučkaFor cross-country skating, it is advantageous that the sole of the shoe is not parallel to the upper surface of the ski, but that it is tilted outwards, that is, when standing upright, it stands on o. The advantage of the inclination of the sole is expressed in the phase of tear off. The ski should be positioned on the inside edge so that the ski does not slip away when lifting. This is done by pushing the knee inwards. Due to the slope of the sole, it is a ski

2o že v začetnem stanju postavljena na robnik in kolena ni potrebno potisniti navznoter v tolikšni meri, kot je to potrebno ob vzporednem podplatu čevlja in smučke. Dosedanje rešitve so nagib reševale z nagnjenim podnožjem vezi ali z vezjo, ki je sama po sebi nagnjena. Slabost te rešitve je v tem, da je tako smučko možno uporabljati samo na eni nogi.2o is already positioned on the curb in its initial state and the knees need not be pushed inwards to the extent necessary with the sole of the shoe and the ski. Previous solutions solved the slope with a sloping base of the bond or with a bond that is inclined by itself. The disadvantage of this solution is that such a ski can only be used on one leg.

Vse vezi za tek na smučeh, ki za vpetje uporabljajo osovino na smučarskem čevlju, so izdelane tako, da je osovina na čevelj pritrjena v dveh točkah, na levem in desnem robu podplata. Vez osovino zagrabi med levim in desnim vpetjem osovine. Za boljšo stransko stabilnost bi bila čim daljša osovina ugodna, vendar je pri čevljih z vpetjem osovine na zunanjih robovih dolžina osovine omejena s tema robovoma.All cross-country ski bindings that use an axle on the ski boot are made so that the boot axle is fixed at two points on the left and right edges of the sole. It grabs the shaft between the left and right shaft mountings. For better lateral stability, a longer axle would be advantageous, but for shoes with an axle mounting on the outer edges, the axle length is limited by these edges.

Opisani tehnični problem je rešen z stopalno varnostno vezjo za tek na smučeh in s pripadajočim tekaškim čevljem z nastavljivim stranskim naklonom. Bistvo predložene rešitve je, da je točka vpetja premaknjena pod stopalo v točko, kjer je odriv najmočnejši. Os vrtenja in čevelj sta dvignjena nad smučko toliko, da je v zadnji fazi odriva omogočen zadosten dvig petnega dela čevlja, zato čevlja spredaj ni potrebno ukriviti is navzgor. Podplat čevlja je fleksibilen in se v zadnji fazi odriva po potrebi ukrivi, da se peta dovolj dvigne nad smučko. Smučarski tekaški čevelj je izveden tako, da je možno nastavljanje stranskega naklona podplata čevlja glede na osovino, ki služi za vpetje v stopalno varnostno vez. Vpetje smučarskega čevlja na varnostno vez je izvedeno tako, da ob prevelikih obremenitvah spusti čevelj.The technical problem described is solved by a foot safety cross-country skiing shoe and an associated running shoe with adjustable lateral inclination. The point of the proposed solution is that the mounting point is moved below the foot to the point where the tear-off is strongest. The axis of rotation and the shoe are raised above the ski in such a way that in the last phase of the ejection it is possible to lift the heel of the shoe sufficiently, so that it is not necessary to bend the shoe upwards from the front. The sole of the shoe is flexible and, in the final phase, it bends when necessary to allow the heel to lift sufficiently above the ski. The ski running shoe is designed in such a way that it is possible to adjust the lateral inclination of the sole of the shoe with respect to the shaft, which is used to secure the foot safety harness. Attaching the ski boot to the safety harness is carried out by lowering the shoe under heavy loads.

S pomikom točke vpetja pod stopalo so odpravljene vse tehnične slabosti vezi z vpetjem na sprednjem delu čevlja. Dolžina podplata čevlja, kjer se čevelj ob nagibu noge v stran torzijsko zvija, je pri stopalni varnostni vezi krajša kot pri vezeh z vpetjem spredaj, tako da se čevelj pri odrivu precej manj torzijsko zvija. Zaradi tega je prenos sile z noge tekača na smučko bolj direkten. To je posebej pomembno v fazi odriva drsalnega koraka, ko tekač nogo pomakne navznoter, da smučko postavi na robnik in s tem dobi oporo za odriv. Zaradi boljše torzijske stabilnosti je smučka postavljena na robnik z manjšim nagibom noge navznoter, za kar je potrebno manj energije, noga pa ostane v bolj naravni legi za odriv. Posledica tega je eksplozivnejši odriv.Moving the point of attachment below the foot eliminates all the technical weaknesses of the attachment to the front of the shoe. The length of the sole of the shoe, where the shoe torsionally twists sideways when tilting the leg, is shorter with the foot safety link than with the front linkage, so that the shoe twists considerably less when torn off. This makes the transfer of force from the runner's legs to the ski more direct. This is especially important at the stage of the skate step, when the runner moves his foot inward to place the ski on the curb, thereby providing a footing support. For better torsional stability, the ski is placed on the curb with less leg tilt inwards, which requires less energy and the leg stays in a more natural position for undoing. This results in a more explosive burst.

Stopalno varnostna vez s čevljem z nastavljivim stranskim naklonom za tek na smučeh po izumu in sklop vezi in čevlja, ki je prikazan na sliki 1 je sestavlja vez 1, ki je nameščena na smučki 2 in uprijemnega elementa 3 z io osjo 10 na podplatu 4 tekaškega čevlja 5.The foot-safety shoe latch with adjustable lateral pitch for cross-country skiing according to the invention, and the shoe and shoe assembly shown in Fig. 1 consists of a lug 1 mounted on a ski 2 and a holding element 3 with an io axis 10 on the sole 4 of the treadmill. shoes 5.

Vez 1 sestavljata podnožje 6 in napenjalni del 7. Del 8 podnožja 6 je z vijaki pritrjen na smučko, del 9 pa je povezan z napenjalnim delom 7. Dela 8 in 9 podnožja tvorita na vsaki strani smučke 2 klešči, s katerimi ob vpetju čevlja 5 podnožje 6 drži os 10, ki se nahaja v uprijemnem elementu 3 is tekaškega čevlja 5.The embroidery 1 is made up of the base 6 and the tensioning part 7. The part 8 of the base 6 is screwed to the ski, and the part 9 is connected to the tensioning part 7. The parts 8 and 9 of the base form on each side of the ski 2 tongs, with which the shoe 5 is engaged. the base 6 is supported by the axis 10, which is located in the upright member 3 and the running shoe 5.

Dela 8 in 9 sta zgoraj oblikovana tako, da je stičišče v obliki črke V. Ob vstopu se zaradi pritiska osi 10 navzdol vzmet 11 stisne in del 9 odmakne. S tem je omogočen avtomatski vstop. Ko je os 10 dovolj globoko v kleščah, se del 9 zaradi vzmeti 11 pomakne nazaj v prvotno lego in s tem se klešče zaprejo in držijo os 10 in posledično tudi čevelj 5.Parts 8 and 9 are designed above so that the junction is V-shaped. Upon entry, the spring 11 is pressed down by the axle pressure 10, and part 9 moves away. This enables automatic entry. When the axis 10 is sufficiently deep in the pliers, the part 9 moves back to its original position due to the spring 11, thereby closing the pliers and holding the axis 10 and consequently the shoe 5.

Del 9 ima zob 12 na spodnjem delu oblikovan tako, da je poševen glede na ravnino smučke 2. Ob velikem pritisku osi 10 navzgor na zob 12 se vzmet 11 stisne in del 9 odmakne naprej. Os 10 izskoči iz klešč in s tem je izveden varnostni element vezi.Part 9 has a tooth 12 at the bottom formed in such a way that it is oblique with respect to the plane of the ski 2. Upon great pressure of the axis 10 upwards on the tooth 12, the spring 11 is compressed and the part 9 moves forward. The axle 10 pops out of the pliers and the safety element of the link is made.

Dela 8 in 9 sta zgoraj ukrivljena navzven, s čimer je omogočen lažji vstop v vez ter čim daljša razdalja med levimi in desnimi kleščami, kar omogoča boljšo stransko stabilnost. Uprijemni element 3 je konusno oblikovan, da se prilega kleščam, ko je čevelj 5 vpet v vez 1. Del 8 ima izboklino 19, ki preprečuje, da bi se del 9 gibal v vertikalni smeri.Parts 8 and 9 are bent outwards above to allow easier entry into the bond and to maximize the distance between the left and right pliers, providing better lateral stability. The retaining element 3 is conically shaped to fit the pliers when the shoe 5 is clamped into the tie 1. Part 8 has a protuberance 19 that prevents the part 9 from moving in a vertical direction.

Napenjalni del 7 je sestavljen iz ohišja 13, vzmeti 11, dveh vzvodov 15 in napenjalne ročice 16. Ohišje 13 ima na vsaki strani podolgovato luknjo io 17, po kateri se giblje os 18. Vzmet 11 je na eni strani povezana z osjo 18, na drugi strani pa z delom 9 podnožja 6. Vzvoda 15 sta na eni strani ležajno povezana z osjo 18, na drugi pa z napenjalno ročico 16. Napenjalna ročica 16 je ležajno povezana z ohišjem 13. Ko je napenjalna ročica 16 v spodnji legi, je os 18 pomaknjena nazaj, vzmet 11 je napeta in is del 9 podnožja 6 potiska nazaj. Dela 8 in 9 tvorita zaprte klešče in držita os 10, ali sta pripravljena za avtomatski vstop. Ko je napenjalna ročica 16 v zgornji, dvignjeni legi, se os 18 pomakne naprej, vzmet 11 je razbremenjena in za seboj potegne del 9 podnožja 6. Dela 8 in 9 podnožja 6 tvorita odprte klešče in ne držita osi 10. Čevelj 5 ni vpet v vez 1 in se lahko loči od vezi 1.The tensioning part 7 consists of a housing 13, a spring 11, two levers 15 and a tensioning lever 16. The housing 13 on each side has an elongated hole io 17 along which the axis 18. The spring 11 is connected on one side to the axis 18, to on the other hand, part 9 of the base 6. The levers 15 are connected to the axle 18 on one side and the tensioning lever 16 on the other. The tensioning lever 16 is connected to the housing 13. When the tensioning lever 16 is in the lower position, the axis 18 is pushed back, spring 11 is tensioned, and is part 9 of the base 6 is pushed back. Parts 8 and 9 form closed clamps and hold the axis 10, or are ready for automatic entry. When the tensioning lever 16 is in the upper raised position, the axle 18 moves forward, the spring 11 is relieved, and pulls part 9 of the base 6 behind. Parts 8 and 9 of the base 6 form open forceps and do not hold the axis 10. The shoe 5 is not engaged in bond 1 and can be separated from bond 1.

Nastavljanje stranskega naklona je izvedeno tako, da uprijemni element 3 zgoraj ni raven ampak rahlo koničaste oblike. Na sredini je preko tečaja 20 povezan s podplatom 4. Os tečaja poteka v vzdolžni smeri čevlja.The lateral inclination is adjusted so that the upright element 3 above is not straight but slightly tapered. In the middle, it is connected to the sole 4 via the hinge 20. The hinge axis runs in the longitudinal direction of the shoe.

Uprijemni element 3 se okrog osi tečaja 20 zavrti za majhen kot zaradi koničaste oblike. S tem lahko čevelj 5 nagnemo v stran glede na zgornjo površino smučke 2. Z vijakoma 21 se uprijemni element fiksira na želeni kot. Uprijemni element 3 je lahko izveden tudi brez tečaja, tako da je fiksno pritrjen na podplat 4. Taka izvedba ne omogoča nastavitve stranskega naklona, pač pa je čevelj 5 nagnjen za določen kot, ki se lahko spreminja z obliko uprijemnega elementa 3.The mounting element 3 rotates about a small angle around the axis of the hinge 20 due to its tapered shape. This allows the shoe 5 to be tilted to the side relative to the upper surface of the ski 2. With screws 21, the retaining element is fixed to the desired angle. The mounting element 3 can also be made without a hinge, so that it is fixed to the sole 4. Such an embodiment does not allow the lateral tilt to be adjusted, but the shoe 5 is inclined by a certain angle, which can be varied by the shape of the mounting element 3.

Pod petnim delom čevlja 5 se nahaja distančnik 22, ki skrbi za pravi nagib čevlja 5 glede na smučko 2 v petni stabilni legi.Below the heel 5 of the shoe 5 is a spacer 22, which takes care of the true inclination of the shoe 5 with respect to the ski 2 in the heel stable position.

io Pod sprednjim delom podplata se nahaja fleksor 23, ki zagotavlja, da prehod iz petne stabilne lege v prstno stabilno lego ni sunkovit.io There is a flexor 23 below the front of the sole, which ensures that the transition from the heel stable position to the finger stable position is not jerky.

Zaradi pomika točke vpetja pod stopalo na točko, kjer je odriv najmočnejši, se izboljša zadnja faza odriva, ko se dvigne petni del čevljaBy shifting the point of engagement below the foot to the point where the tear is strongest, the last tear phase improves as the heel of the shoe rises

5. Tekač se v tej fazi ne odriva več od prstov, kot se to zgodi pri vezeh z vpetjem spredaj, pač pa odrine od točke na stopalu, kjer je odriv najmočnejši, zato je odriv boljši. Druga ugodna posledica premaknitve točke vpetja pod stopalo je manjše utrujanje stopalnih mišic, ker se ni potrebno odrivati od prstov.5. At this stage, the runner does not deviate further from the toes than is the case with the front linkage connections, but rather pushes away from the point at the foot where the ebb is strongest, so the ebb is better. Another advantage of moving the clamping point below the foot is less fatigue of the foot muscles because it does not have to be pulled away from the toes.

Stopalna varnostna vez s čevljem z nastavljivim stranskim naklonom za tek na smučeh po izumu v predloženi konstrukcijski varianti omogoča v zadnji fazi odriva zadosten dvig petnega dela čevlja 5, s tem da je oblika čevlja 5 anatomsko enaka dosedanji. Čevelj 5 se zaradi dvignjenosti nad smučko 2 in zaradi točke vpetja pod podplatom 4 obnaša po principuThe foot safety link with a shoe with adjustable lateral slope for cross-country skiing according to the invention in the present design variant enables in the last phase of the tear off sufficient lifting of the heel portion of the shoe 5, with the shoe 5 being anatomically identical to the present one. Due to its elevation above the ski 2 and the mounting point of the sole 4, the shoe 5 behaves according to the principle

-1010 gugalnice. Ob pokončni stoji je težišče za točko vpetja, zato je čevelj 5 v petni stabilni legi, petni del se v tej legi dotika smučke. Ob nagibanju naprej ali ob dvigovanju petnega dela se težišče premika naprej proti točki vpetja. V določenem trenutku se težišče premakne naprej od točke vpetja proti prstnemu delu čevlja 5. V tem trenutku se čevelj 5 postavi v prstno stabilno lego, v tej legi se petni del dvigne in čevelj 5 se smučke dotika v prstnem delu. Da prehod iz petne stabilne lege v prstno stabilno lego ne bi bil sunkovit, se pod sprednjim delom čevlja nahaja fleksor 23. Bolj ko je težišče premaknjeno naprej od točke vpetja, bolj se fleksor 23 stisne io zaradi večjega navora.-1010 swings. The upright is the center of gravity for the point of attachment, so shoe 5 is in a heel stable position, the heel is in this position touches the ski. When tilting forward or lifting the heel, the center of gravity moves forward towards the point of attachment. At some point, the center of gravity moves forward from the point of attachment towards the toe portion of the shoe 5. At this point, the shoe 5 is placed in the toe stable position, in this position the heel portion is raised and the shoe 5 is touched in the toe. In order to prevent the transition from the heel stable position to the finger stable position, a flexor 23 is located under the front of the shoe. The more the center of gravity is moved forward from the clamping point, the more the flexor 23 compresses io due to the higher torque.

Os 10 na uprijemnem elementu 3, ki služi za vpetje čevlja 5 v podnožje 6 vezi 1, je na čevelj 5 pritrjena na sredini in ne na obeh koncih, kot je bilo pri dosedanjih vezeh. Zaradi tega podnožje 6 zagrabi os 10 na obeh koncih, ki sta prosta in ne na sredini, kot pri dosedanjih vezeh. Os 10 je vpeta na večji dolžini in zaradi tega je dosežena večja stranska stabilnost.The axis 10 on the retaining element 3, which is used to secure the shoe 5 to the base 6 of the tie 1, is fixed to the shoe 5 in the middle and not at both ends, as was the case with the previous ties. As a result, the base 6 grabs the axis 10 at both ends, which are free and not at the center, as in previous ties. The axle 10 is mounted on a longer length and thus provides greater lateral stability.

Smučarski tekaški čevelj 5 ima možnost nastavljanja stranskega naklona, kar pride v poštev predvsem pri drsalni tehniki smučarskega teka. V fazi odriva je ugodno, če je čevelj nagnjen navzven glede na smučko, zaradi česar robnik da boljšo oporo za odriv. Možnost nastavljanja stranskega naklona je pozitivna zaradi različnih zahtev za različne snežne pogoje. Bolj ko je sneg trd, večja nagnjenost je potrebna za dobro oporo odriva. Nastavljanje stranskega naklona na tekaškem čevlju 5 v primerjavi z nastavljanjem na smučki 2 je boljše, ker je pri tejThe ski running shoe 5 has the possibility of adjusting the lateral inclination, which is especially useful in skating technique. It is advantageous during the casting phase when the shoe is tilted outwards relative to the ski, which gives the curb better support for the lift. The ability to adjust the side slope is positive because of different requirements for different snow conditions. The more hard the snow, the more inclined it is necessary for a good grip. Adjusting the side incline on the running shoe 5 is better than adjusting on the ski 2 because

-1111 rešitvi možno menjati smučki 2 z leve noge na desno in obratno, pri nastavljanju na smučki 2 pa to ni možno, ker je le ta nastavljena samo za eno nogo.The -1111 solution can be changed from ski left 2 to right and vice versa, but when ski 2 is adjusted this is not possible because it is only set for one leg.

Kljub povečani razdalji med smučko 2 in čevljem 5, ki omogoča dvigovanje petnega dela čevlja 5, pa je dvigovanje še vedno bolj omejeno, kot pri vezeh z vpetjem spredaj, kjer je čevelj teoretično možno okrog osi vpetja zavrteti za do 90°. To bi lahko bilo usodno pri padcu, zato izum vsebuje tudi varnostni element.Despite the increased distance between the ski 2 and the shoe 5, which allows the heel of the shoe 5 to be lifted, lifting is still more limited than with the front linkage, where the shoe can theoretically be rotated about 90 ° by the shoe axis. This could be fatal in the fall, so the invention also has a safety element.
