PETNI DEL VEZI ZA TEK NA SMUČEH Z USTREZNO OBLIKOVANO PETO TEKAŠKEGA SMUČARSKEGA ČEVLJAFIFTH SKI BINDING WITH A FITTED SHOE FITTING SHOE

Predmet izuma je petni del vezi za tek na smučeh, ki v sklopu z ustrezno oblikovano peto tekaškega smučarskega čevlja omogoča dobro torzijsko stabilnost ob odrivu pri teku na smučeh in onemogoča nabiranje snega med petnim delom vezi in peto tekaškega smučarskega čevlja. Izum spada v razred A63C9/20 mednarodne patentne klasifikacije.The object of the invention is the fifth part of the cross-country skiing bundle, which, in combination with the properly designed heel of the cross-country ski boot, provides good torsional stability when pulled off when cross-country skiing and prevents the accumulation of snow between the fifth part of the cross-country ski boot and the heel. The invention belongs to the class A63C9 / 20 of the international patent classification.

Tehnični problem, ki ga predložena izvedba petnega dela vezi za tek na is smučeh po izumu uspešno rešuje, je zagotavljanje čim boljše torzijske stabilnosti ob odrivu pri teku na smučeh in hkrati zagotavljanje takšnega položaja čevlja in s tem tudi stopala in golenice, ki bo omogočil optimalno pretvorbo odrivne moči in energije tekača v hitrost smučanja. Rešitev zastavljenega tehničnega problem po izumu pa poleg navedenega tudi preprečuje nabiranje snega med petnim delom vezi in peto tekaškega smučarskega čevlja, zaradi česar ne prihaja do oddrsavanja pri odrivu zaradi s snegom zapolnjenih vzdolžnih utorov na peti kot se dogaja pri doslej znanih konstrukcijah.The technical problem that the proposed embodiment of the heel part of the cross-country ski according to the invention successfully solves is to provide the best torsional stability during tearing when skiing, and at the same time to ensure that the position of the shoe and thus the feet and tibia, which will allow optimum converting the rider's power and energy into skiing speed. The solution of the technical problem according to the invention, in addition, prevents the accumulation of snow between the heel part of the link and the heel of the cross-country ski boot, which does not cause slipping during tearing due to snow-filled longitudinal grooves on the heel, as is the case with the known structures.

Ena od znanih rešitev izvedbe petnega dela smučarske vezi je opisana v ameriškem patentu št. US 5,090,723. Rešitev ponuja izbočeno vodilo, ki naj bi v sklopu z vzdolžnim utorom v peti tekaškega smučarskega čevlja onemogočala zdrs čevlja na stran pri odrivu. Problem te rešitve je v tem, da vzdolžni utor po sredini pete, ki v primeru, da je zapolnjen s snegom zmanjšuje stabilnost pri odrivu pri naleganju podplata po celotni dolžini na tekaško vez. Zaradi tega je odriv manj eksploziven.One of the known embodiments of the fifth part of the ski link is described in U.S. Pat. US 5,090,723. The solution offers a convex guide which, in conjunction with the longitudinal groove in the heel of the running ski boot, prevents the shoe from sliding to the side during tearing. The problem with this solution is that the longitudinal groove in the middle of the heel, which, if filled with snow, decreases the tear-off stability when the sole rests along the entire length of the treadmill. This makes the ebb less explosive.

Zastavljen tehnični problem je zadovoljivo rešen s petni delom vezi za tek na smučeh. Bistvo predložene rešitve po izumu je, da je naslon pete io tekaškega smučarskega čevlja na petni del vezi s skrajnima robovoma pete, robova nista zaprta, kar preprečuje nabiranje snega in hkrati daje večjo stabilnost pri odrivu.The technical problem identified is satisfactorily solved with the fifth part of the cross-country skiing link. The essence of the proposed solution according to the invention is that the backrest of the heel and the running shoe on the heel is part of the connection with the extreme edges of the heel, the edges are not closed, which prevents snow accumulation and at the same time gives greater stability in tearing.

Petni del vezi za tek na smučeh po izumu je izveden v enem kosu, pri čemer je osnovni del rahlo izbočeno obiikovan, na obeh straneh poševno is izvedeni stranici pa imata, gledano s strani, trapezasto obliko in ravni zgornji ploskvi. Peta tekaškega smučarskega čevlja je ustrezno prilagojena obliki petnega dela vezi po izumu tako, da sta na zunanji in notranji strani pete izvedena robova z ustrezno oblikovanima naležnima in ujemalnima ploskvama, ki se ujemata s stranicama petnega dela vezi.The fifth part of the cross-country skiing invention according to the invention is made in one piece, the basic part being slightly convex, and on both sides inclined and with the two sides, when viewed from the side, have a trapezoidal shape and flat upper faces. The heel of the cross-country ski boot is suitably adapted to the shape of the heel part of the bond according to the invention so that the outer and inner sides of the heel have edges with properly formed contact and matching surfaces that match the sides of the heel part of the bond.

Z maksimalno možno razdaljo med zgornjima ploskvama stranic petnega dela vezi, kjer peta nalega na vez, je zagotovljena boljša torzijska stabilnost pri odrivu.The maximum possible distance between the upper surfaces of the sides of the heel part of the bond, where the heel rests on the bond, provides better torsional stability during tearing.

Stranici petnega dela vezi sta višji od doslej znanih izvedb, kar zagotavlja takšno lego tekaškega smučarskega čevlja in s tem stopala in golenice, ki omogoči optimalno pretvorbo odrivne moči in energije tekača v hitrost smučanja.The sides of the heel part of the ligament are higher than previously known designs, which provides such a position of the cross-country ski boot and thus the feet and tibia, which enables optimal conversion of the running power and energy of the runner into the speed of skiing.
