Abstract

A heel part of bindings for cross-country skiing in combined technique assures the torsional stiffness of the assembly boot-bindings-ski required for the controlled steering of the ski with regard to the skiing technique and state of the track at the flexible sole of the boot whoose flexibility should be adapted to the anatomically determined flexing of the foot occurring during all phases of the stride at both skiing techniques. The heel part according to the invention is composed of a guide (8) which is fixed on the upper face (9) of the ski (1) behind the heel (5) of the boot (4), and of a stiff movable part (10), one end (11) of which is attached to the guide (8) in a manner allowing its shifting along the longitudinal axis and rotation about the transverse axis of the ski, and the opposite end (12) in a turnable and manually dismountable manner to a bed (6) on the heel (5) of the boot (4), allowing the boot (4) to rotate about the axis in the front bindings. According to the variant design, the heel part is carried out as an upright profile (20) standing at the right angle to the upper face of the ski behind the heel (5) of the boot (4). On its side adjacent to the heel (5), there is a vertical groove (21), while on the heel (5) of the boot (4) there is a backwards projecting spur-like element (22) with an upright flat free end (23) which is mounted into the groove (21) in a manner to allow the free movement in the axial direction and to prevent the movement in the transverse direction.

Petni del vezi za tekaško smučanjeFifth part of cross-country skiing

Predmet izumaThe subject of the invention

Predmet izuma je petni del vezi za tekaško smučanje obeh tehnik, t.j. klasične diagonalne in sodobnejše drsalne.The object of the invention is the fifth part of the cross-country skiing bindings, i.e. classic diagonal and modern skates.

Tehnični problemA technical problem

Tehnični problem je, kako zagotoviti torzij sko togost sklopa čevelj - vez smučka, ki je potrebna za nadzorovano vodenje smučke z oziroma na tehniko smučanja in stanje smučine ob upogljivem podplatu čevlja zaradi prireditve gibkosti čevlja anatomsko določenemu upogibanju narta, kakršno se dogaja v vseh fazah koraka pri obeh tehnikah tekaškega smučanja.The technical problem is how to ensure the torsional rigidity of the shoe assembly - the link of the ski, which is necessary for the controlled running of the ski with or to the ski technique and the condition of the ski with the flexible sole of the shoe due to the adaptability of the shoe's flexibility to anatomically determined flexing of the boot, which occurs in all stages of the step for both cross-country skiing techniques.

Znano stanjeKnown state

Zaradi potrebnega dviga pete čevlja med izvajanjem smuškega koraka pri obeh vrstah tekaškega smučanja, je tekaška vez praviloma izvedena tako, da je čevelj zasukljivo vpet samo na sprednjem delu, medtem ko je peta prosta.Due to the necessary lifting of the heel of the shoe during the performance of the ski step for both types of cross-country skiing, the running shoe is generally made so that the shoe is rotated only on the front part while the heel is free.

Potrebno torzij sko togost sklopa čevelj - vez - smučka zagotavljajo s togim podplatom in vrhnjim delom čevlja, zlasti delom, ki oklepa peto in gleženj. K togosti pripomore tudi dodatna gleženj ska manšeta. Tako oblikovani čevlji dopuščajo anatomsko zahtevano spreminjanje kota med stopalom in golenico vThe necessary torsional rigidity of the shoe-binding-ski assembly is provided by the rigid sole and the upper part of the shoe, especially the part that surrounds the heel and ankle. The extra ankle cuff also contributes to the stiffness. The shoes thus designed allow for an anatomically required change in the angle between the foot and tibia in

Pomanjkljivost teh zasnov je togost podplata, ki preprečuje anatomsko pogojeno gibanje v sklepih med stopalnicami in členki prstov med , kakršno nastopi med koraki v fazi odriva pri obeh tehnikah. Zato je energetski izkoristek tekača nižji.The disadvantage of these designs is the rigidity of the sole, which prevents anatomically conditioned movement in the joints between the feet and the joints of the toes, such as occurs between the steps in the tearing phase in both techniques. Therefore, the energy efficiency of the impeller is lower.

Obstajata vez in čevelj firme Salomon, pri katerih je izveden dvojen spoj čevlja in vezi in sicer pred prsti in nekaj centimetrov nazaj, približno v območjusklepov med prsti in stopalnicami. S tem je omogočeno boljše gibanje navedenih sklepov, vendar pa je togost dvignjene pete glede na smučko nezadovoljiva.There is a Salomon embroidery and shoe with a pair of shoe and embroidery joints in front of the toes and a few inches back, approximately in the joints between the toes and the feet. This enables better movement of the above joints, but the rigidity of the raised heel relative to the ski is unsatisfactory.

Rešitev tehničnega problemaThe solution to a technical problem

Opisani tehnični problem je rešen z novim petnim delom vezi, ki dovoljuje neoviran dvig pete čevlja v posameznih fazah koraka obeh tehnik in hkrati v vseh legah čevlja zagotavlja torzijsko togost pete čevlja, katerega bočna togost nudi bočno oporo gležnju, da dosežemo zaželeno togo zvezo med gležnjem, čevljem in smučko v vseh fazah smučarskega koraka obeh tehnik, s čimer je sproščena možnost zasnove gibkega podplata in vrhnjega dela čevlja v območju sklepov prstov in stopalnic.The described technical problem is solved with a new heel part of the ligament, which allows unimpeded lifting of the heel of the shoe in the individual steps of the steps of both techniques and at the same time in all positions of the shoe provides torsional rigidity of the heel of the shoe, whose lateral stiffness provides a lateral support to the ankle in order to achieve the desired rigid connection between the ankle , shoes and ski at all stages of the skiing step of both techniques, thus freeing the possibility of designing the flexible sole and the upper part of the shoe in the area of the joints of the toes and feet.

Petni del po izumu je zasnovan tako, da pomični togi element vezi na enem koncu zasukljivo vprijemlje v peto čevlja, medtem ko je s svojim nasprotnim koncem prosto pomičen v osni smeri smučke, zasukljiv v ravnini, pravokotni na drsno ploskev smučke in bočno neupogljiv v vodilu, ki je nameščeno na smučki za peto čevlja. Hod premičnega elementa v osni smeri smuče je tolikšen, da omogoča zasuk pete čevlja za približno pravi kot. Ker pa je ta element neupogljiv v obeh bočnih smereh in hkrati samo zasukljivo vpet v peto čevlja, je dosežena torzij ska togost vpetja čevlja glede na smučko v vseh legah čevlja glede naThe fifth part according to the invention is designed so that the movable rigid element of the link at one end swivels into the heel of the shoe, while its opposite end is freely movable in the axial direction of the ski, rotatable in a plane perpendicular to the sliding surface of the ski and laterally inflexible in the guide , which is mounted on the ski for the heel of the shoe. The travel of the moving element in the axial direction of the ski is such that it allows the heel of the shoe to rotate about the right angle. However, since this element is non-rigid in both lateral directions and at the same time only rotatably clamped in the heel of the shoe, torsional rigidity of the shoe clamping relative to the ski in all shoe positions relative to the ski is achieved.

Zato lahko vso moč in energijo tekač uporabi samo za efektivne gibe smučanja.Therefore, the runner can use all the power and energy only for effective skiing movements.

V drugi izvedbi je petni del izveden kot žlebast profil, kije nameščen na zgornji ploskvi smučke tik za peto čevlja in sicer tako, da teče žleb pravokotno na zgornjo ploskev smučke. Na peti je izvedena ostroga, katere nazaj prosto moleči del leži v žlebu vezi. V žlebu potekajoči del ostroge je tako oblikovan, da onemogoča nagibanje pete oziroma celega čevlja levo in desno ob neoviranem dvigu in spuščanju pri poljubnih smučarskih korakih.In another embodiment, the heel portion is made as a groove profile which is mounted on the upper surface of the ski just behind the heel of the shoe by running the groove perpendicular to the upper surface of the ski. A heel is made on the heel, the back of which is freely protruding in the groove of the ligaments. The groove running in the groove is designed to prevent the heel or the whole shoe from tilting left and right with unobstructed lifting and lowering at any ski step.

Podrobneje bo bistvo izuma pojasnjeno z opisom dveh izvedbenih primerov in risb, na katerih kaže.The essence of the invention will be explained in more detail by the description of two embodiments and the drawings in which it is shown.

sl. 1 stranski pogled srednjega dela smučke s čevljem, ki nalega na smučko in vezjo po prvem izvedbenem primeru izuma , sl. 2 isto z dvignjenim čevljem v fazi odriva, sl. 3 isto v tlorisu, sl. 4 stranski pogled srednjega dela smučke s čevljem in vezjo po drugem izvedbenem primeru, sl. 5 isto v tlorisu.FIG. 1 is a side view of the middle portion of a ski with a shoe that rests on the ski and the circuit according to the first embodiment of the invention; FIG. 2 is the same with the raised shoe in the ejection phase; FIG. 3 is the same in plan, FIG. 4 is a side view of the middle portion of the ski with the shoe and the embroidery according to another embodiment, FIG. 5 same in floor plan.

Prvi izvedbeni primerThe first embodiment

Kot prikazujeta sl. 1 in 2 je na smučki 1 nameščen prednji del 3 vezi poljubnega tipa, ki dovoljuje dvig in hkrati zasuk čevlja 4 s petnim delom navzgor in naprej. Na peti 5 čevlja 4 je izvedeno ležišče 6 za vprijem vezi, ki omogoča zasukljivost v navidezni prečni osi, ki poteka vzporedno z osjo zasukam čevlja 4 v prednjem delu 3 vezi.As FIG. 1 and 2, ski 1 is provided with a front part 3 of any type of tie, which allows the shoe 4 to be lifted and simultaneously rotated with the heel part up and forward. On the heel 5 of the shoe 4, there is a bearing attachment 6, which allows rotation in a virtual transverse axis, which runs parallel to the pivot axis of the shoe 4 in the front part 3 of the bond.

27396.doc/ll-00/D22-Vr27396.doc / 11-00 / D22-Vr

Petni del 7 vezi je izveden iz vodila 8, kije pritrjeno na zgornji ploskvi 9 smučke 1 za peto 5 čevlja 4 in togega pomičnega dela 10, katerega en konec 11 je pomično vpet v vodilo 8, nasprotni konec 12 pa v ležišče 6 na peti 5 čevlja 4.The heel part 7 of the link is made of guide 8, which is secured to the upper surface 9 of the ski 1 by the heel 5 of the shoe 4 and the rigid movable part 10, one end 11 of which is pivotally mounted in the guide 8 and the opposite end 12 into the bearing 6 on the heel 5 shoes 4.

V vodilu 8 sta izvedena v osni smeri smučke potekajoča utora 13 ob njegovih bočnih robovih. V utorih 13 je prosto pomično nameščeno vodilo 8. Ob utorih 13 je na strani pete 5 čevlja 4 izveden omejilnik 14 pomika z dušilnikom 15 zaustavitve pomičnega dela 10.In the guide 8, the grooves 13 running along its lateral edges are made in the axial direction of the ski. A guide 8 is freely mounted in the grooves 13. A groove 14 is provided on the side of the heel 5 of the shoe 4 with a silencer 15 to stop the moving part 10.

Zasukljiv in ročno razstavljiv spoj pomičnega dela 10 in pete 5 čevlja 4 je izveden na poljuben znan način, kije znan iz drugih podobnih spojev v vezeh za tekaško in turno smučanje.The rotatable and manually disassembled joint of the movable part 10 and the heel 5 of the shoe 4 are made in any known manner known from other similar joints in cross-country and touring skiing connections.

Dolžina pomika pomičnega dela 10 v vodilu 8 je tolikšna, da omogoča dvig pete 5 čevlja 4, kolikor je potrebno za tekaški korak, predvideno do pravega kota.The length of the displacement of the movable part 10 in the guide 8 is such that it allows the heel 5 of the shoe 4 to be raised as much as is necessary for the running step provided to the right angle.

Kerje pomični del 10 vpet v vodilu 8v dveh točah na isti navidezni prečni osi in hkrati v peti 5 čevlja 4 v osi,ki poteka vzporedno z navidezno osjo v vodilu 8, je peta 5 čevlja 4 torzijsko togo vpeta na smučki v katerikoli njeni legi oziroma naklonu glede na smučko. S tem se sprosti potreba po togosti podplata, ki je lahko spet gibek kot pri drugih čevljih, da omogoča upogibanje v sklepih stopalčnih kosti in prstov, kar je bil tudi cilj izuma.Since the movable part 10 is fixed in the guide 8 in two points on the same apparent transverse axis and at the same time in the heel 5 of the shoe 4 in an axis running parallel to the virtual axis in the guide 8, the heel 5 of the shoe 4 is rigidly fixed to the skis in any position thereof, respectively. slope relative to the ski. This relieves the need for rigidity of the sole, which can again be flexible as with other shoes, to allow flexion in the joints of the foot bones and toes, which was also an object of the invention.

Drugi izvedbeni primerAnother embodiment

V drugem izvedbenem primeru je za peto 5 čevlja 4 na zgornji ploskvi smučke nameščen pokončen oziroma pravokotno nanjo stoječ profil 20, na katerega peti 5 priležni strani je izveden pokončen žleb 21. Na peti 5 čevlja 4 je izveden nazaj štrleč, kot ostroga zasnovan element 22 s pokončnim ploščatim prostim koncem 23. Ploščat konec 23 elementa 22 leži v žlebu 21 osno prosto pomično. Zaradi ploščate oblike konca 23 je preprečeno njegovo nagibanje levo desno v žlebu 21.In the second embodiment, a heel profile 20 is erected for the heel 5 of the shoe 4 on the upper surface of the ski, on which the heel 21 is erected on the fifth 5 adjacent sides. The heel-like element 22 is projected back on the heel 5 of the shoe 4. with the erect flat free end 23. The flat end 23 of the element 22 lies axially freely in the groove 21. The flat shape of the end 23 prevents it from tilting from left to right in groove 21.

27396. doc/ll-00/D22-Vr27396. doc / ll-00 / D22-Vr

Ker je element 22 togo nameščen na peti 5 je s tem tudi peta 5 pri dvigu in spuščanju torzijsko togo vodena v vodilu 8 v katerikoli njeni legi.Since the element 22 is rigidly mounted on the heel 5, the heel 5 is thus guided in the guide 8 in any position when lifting and lowering it.

S tem je dosežen isti učinek na čevelj kot pri prvem izvedbenem primeru.This achieves the same effect on the shoe as in the first embodiment.

Razume se, da lahko strokovnjak s tega področja na osnovi poznavanja izuma oziroma njegovih opisanih izvedbenih primerov zasnuje tudi druge izvedbe, ne da bi se oddaljil od bistva izuma, kije opredeljeno v sledečih patentnih zahtevkih.It is understood that one of skill in the art may, on the basis of knowledge of the invention or its embodiments described, conceive other embodiments without departing from the spirit of the invention as defined in the following claims.
