Abstract

Varnostni sistem za odpenjanje smuči z aktivnim izmetom rešuje problem odpenjanja smuči in vezi s smučarskih čevljev v kritičnih situacijah na osnovi sproščene energije ustrezne količine pirotehničnih zmesi ali generatorjev plina, ki so del elektronskega sistema za sprožanje napajanega z baterijo, ki ga smučar žično ali brezžično sproži sam ali s pomočjo dodatnih senzorjev. Sistem predvsem preprečuje poškodbe nog pri padcih, kjer se sile s smuči prenašajo na noge smučarja. Aktivno odpenjanje smuči omogoča hiter izmet smuči v nekaj milisekundah, smučar pa tenko v nadaljevanju padca lažje nadzoruje svoje gibanje. Napravi za horizontalni in vertikalni izmet smuči in vezi lahko po potrebi namestimo in uporabljamo kombinirano ali ločeno. Aktivni sistem odpenjanja smuči omogoča dodatno varovanje smučarja pred poškodbami in ne vpliva na delovanje obstoječega klasičnega pasivnega sistema odpenjanja smuči, majhna masa in velikost naprav pa ne na dinamiko smučanja in karakteristike smučarske opreme.The safety system for the removal of an active-eyed skis solves the problem of the disconnection of the skis and the connection of ski boots in critical situations on the basis of the released energy of the corresponding quantity of pyrotechnic mixtures or gas generators forming part of the electronic triggering system powered by a battery that the skier is wired or wireless activated alone or with the help of additional sensors. In particular, the system prevents the damage of the legs in the fall, where the forces from the skis are passed on to the skier's feet. The active ski lift allows a quick sweep of the skis in a few milliseconds, while the skier can easily control his movement in the fall. The devices for horizontal and vertical ejection of skis and bindings can be installed and used when combined or separately. An active ski lift system provides additional protection for the skier against damage and does not affect the operation of the existing classic passive ski lift system, while the small weight and size of the equipment does not affect the skiing dynamics and characteristics of the ski equipment.

Description

Predmet izuma so sistem in izmetalni napravi za aktivno odpenjanje smuči v kritičnih situacijah na osnovi potisne sile sproščene energije pirotehničnih zmesi ali generatorjev plina.The object of the invention is a system and ejectors for actively releasing skis in critical situations based on the thrust force of the released energy of pyrotechnic mixtures or gas generators.

Tehnični problem, ki ga rešuje izum, je konstrukcija izmetalnih naprav ter sistem hitrega in zanesljivega aktivnega odpenjanja smuči, ki ga smučar žično ali brezžično sproži sam ali s pomočjo dodatnih senzorjev, ko ugotovi in oceni, da smučanja več ne kontrolira in padca ne bo mogoče preprečiti.A technical problem solved by the invention is the construction of ejectors and a system of rapid and reliable active ski unplugging, which the skier can wire himself or wirelessly alone or with the help of additional sensors, when he finds and estimates that skiing will no longer be controlled and it will no longer be possible to fall. prevent.

Opis problema in dosedanjih rešitevDescription of the problem and solutions to date

Prvenstveno je sistem namenjen za aktivno varovanje predvsem profesionalnih smučarjev pred poškodbami nog in telesa pri različnih smučarskih disciplinah, še posebej pri tistih, kjer se dosegajo velike hitrosti ali je verjetnost padcev s poškodbami zelo velika (smuk, superveleslalom, smučanje prostega sloga, akrobatsko smučanje, smučarski skoki...).Primarily, the system is designed to actively protect professional skiers from injuries to the legs and body in various skiing disciplines, especially in those where high speeds are achieved or the likelihood of falls with injuries is very high (skiing, super giant slalom, freestyle skiing, acrobatic skiing, ski jumping...).

Pri sedaj uporabljenem, pasivnem odpiranju vezi smučk mora nanje delovati določena, vnaprej nastavljena sila na vezi, da pride do njihovega odpetja s smučarskih čevljev.With the now used passive opening of the ski ties, they must be acted upon by a predetermined force on the ski ties in order to open them from the ski boots.

V večini primerov je to zadostno, v nekaterih pa se zaradi smeri in dinamike delovanja sil na vezi odpenjanje zgodi prepozno ali se sploh ne zgodi pri dani nastavljeni sili, kar lahko privede do hudih poškodb, predvsem v predelu nog.In most cases, this is sufficient, but in some cases, due to the direction and dynamics of the forces acting on the ligament, the release occurs too late or does not occur at any given set force, which can lead to severe injuries, especially in the leg area.

V primeru pravočasnega aktivnega izmeta smuči do teh obremenitev, ki so posledica udarcev smuči ob podlago in druge predmete, ne pride. Aktivni sistem odpenjanja smuči tako v prvi vrsti preprečuje poškodbe nog pri padcih, kjer se sile s smuči prenašajo na noge smučarja. Smučar se z izmetom smuči izogne najhujšim poškodbam, ki so posledica velikih sil, ko se smuči zagozdijo ob snežno podlago ali druge predmete.In the event of timely active ejection of the skis, these loads resulting from the impact of the skis against the ground and other objects do not occur. The active system of releasing the skis prevents, in the first place, injuries to the legs during falls, where forces from the skis are transmitted to the skier's feet. By ejecting the skier, the skier avoids the most serious injuries caused by heavy forces when the skis are stuck against a snow base or other objects.

Sistem preprečuje tudi poškodbe, ki bi nastale kot posledica udarcev smuči v smučarja, saj smuči v zgodnji fazi padca potisne proč od smeri gibanja smučarja. Ko sistem odpne smuči, postane smučar okretnejši in lahko v nadaljevanju padanja posveti pozornost pravilnim gibom in drži telesa, s katerimi ublaži padec ter posledično lahko tako zmanjšuje možnost dodatnih poškodb celotnega telesa.The system also prevents damage that would result from the impact of the skis on the skier, as it pushes the skier away from the skier's direction in the early phase of the fall. As the system recovers, the skier becomes more agile and can continue to pay attention to the correct movements and postures to the body, which mitigates the fall, and thus can reduce the potential for additional damage to the entire body.

Na področju aktivnega odpenjanja smuči je bilo do sedaj ponujenih zelo malo rešitev. Dosedanje patentirane rešitve predstavljajo dimenzijsko relativno velike naprave, običajno montirane na smučko za zadnjo vez. Izmet dosežejo bodisi z razmikom vezi (patent US2005167950), z uporabo stisnjenih plinov ali elektrovalov (AU8120701, EP1386644).So far, very few solutions have been offered in the area of active ski lifting. The patented solutions to date represent relatively large sized devices, typically mounted on a back link ski. Ejection is achieved either by bond spacing (patent US2005167950), by using compressed gases or electrodes (AU8120701, EP1386644).

* ·* ·

Da rešitve še niso razvite in uporabljene, je razvidno iz tega, da aktivnih načinov izmetov smuči ne uporabljajo profesionalni smučarji, saj se tudi pri zelo tveganih smučarskih panogah še vedno uporabljajo klasične, pasivne oblike izmetov smuči. Posledično se še vedno pogosto dogajajo težje poškodbe pri padcih, večinoma zaradi omenjenih pomanjkljivosti, ki jih ima pasivno odpenjanje s prednapetimi vezmi.The fact that the solutions have not yet been developed and applied can be seen in the fact that active skiers are not used by professional skiers, since even in the high-risk industries, classic, passive forms of ski ejections are still used. As a result, more severe fall injuries continue to occur frequently, largely due to the aforementioned disadvantages of passive loosening with prestressed ties.

Opis izumaDescription of the invention

Do sedaj nerešen problem je izvedba aktivnega sistema odpenjanja smuči, ki s svojo obliko, velikostjo, maso in montažo ne bo spremenil karakteristik smučarske opreme in dinamike smučanja ob hkratnem zagotavljanju enostavnega, varnega in hitrega aktivnega izmeta smuči pred ali med padcem smučarja.An unresolved problem so far is the implementation of an active ski unblocking system, which by its shape, size, weight and mounting will not change the characteristics of the ski equipment and the dynamics of skiing while ensuring easy, safe and fast active ejection of the skis before or during the fall of the skier.

Pri izumu je problem rešen s sistemom in napravami, ki omogočajo izredno hitro in zanesljivo odpenjanje smuči v nekaj milisekundah z aktivno silo linearnega pogona, ki je polnjen z generatorjem plina ali pirotehničnim sredstvom, katerega žično ali brezžično aktivira (vžge) pripadajoč elektronski sprožilni sistem. Pri vžigu linearnega pogona hitro naraste tlak, ki služi za potisno silo pogona.In the invention, the problem is solved by a system and devices that enable extremely fast and reliable release of the ski in a few milliseconds by the active force of a linear actuator, which is filled with a gas generator or a pyrotechnic device, which wire or wirelessly activates the associated electronic trigger system. When the linear actuator is ignited, the pressure that acts on the propulsion force of the actuator rapidly increases.

Izum je opisan in prikazan na slikah, ki prikazujejo:The invention is described and shown in the figures showing:

sl. 1 Namestitev aktivnega sistema za odpenjanje smuči sl. 2 Izmetalna naprava za horizontalno odpenjanje smuči in vezi s smučarskih čevljev sl. 3 Izmetalna naprava za vertikalno odpenjanje smuči in vezi s smučarskih čevljevFIG. 1 Installation of the active ski release system Fig. 2 Ejector device for horizontal unbending of skis and ties from ski boots. FIG. 3 Ejector device for vertically releasing skis and ties from ski boots

Aktivni linearni pogoni za horizontalno in vertikalno odpenjaje smuči s smučarskih čevljev se namestijo na obe smučki pod smučarskimi čevlji oz. med sprednjo in zadnjo vez (sl. 1). Pogoni naprav za izmet energijo pridobivajo iz pirotehničnih zmesi ali generatorjev plinov, kar omogoča kratek reakcijski čas, ki se meri v nekaj milisekundah. Odpenjanje sproži smučar oz. senzorji s pomočjo elektronskega sistema. Elektronski sistem se napaja iz baterije. Potrebne sile za odpenjanje delujejo samo med smučmi in čevlji, saj se sile pri odpenjanju ne prenašajo na smučarja. To preprečuje neposredne poškodbe telesa zaradi sil, ki bi nastale pri obstoječih vezeh, kakor tudi močno zmanjšajo možnosti udarca smučarja s smučmi, saj jih sistem lahko pravočasno odrine od smeri gibanja smučarja.Active linear actuators for horizontal and vertical lifting of skis from ski boots shall be installed on both skis below the ski boots or. between the anterior and posterior ligaments (Fig. 1). The drives of ejectors are extracted from pyrotechnic mixtures or gas generators, allowing a short reaction time, measured in a few milliseconds. The start is triggered by the skier and sensors using an electronic system. The electronic system is powered by a battery. The forces required for the release work only between the skis and the shoes, since the forces are not transmitted to the skier during the release. This prevents direct damage to the body due to the forces that would result from the existing connections, as well as greatly reduce the chances of the skier hitting the skis, since the system can push them away from the skier's direction in a timely manner.

Potrebni potisni sili Fv in FH zagotovimo z ustrezno količino zmesi generatorja plina ali pirotehnične zmesi. Hiter izmet smuči omogoča eksplozivna verižna kemijska reakcija zmesi (sl. 3). Izmet lahko sproži smučar sam npr. s pritiskom na nameščena tipala v smučarski palici ali rokavici oz. s stiskom zob, če je tipalo nameščeno v ustih. Nameščeni senzorji na smučeh lahko smučarju pomagajo pri vklopu sistema oz. v določenih primerih sami sprožijo sistem odpenjanja smuči.The required thrust forces F v and F H are provided by an adequate amount of gas generator or pyrotechnic mixture. The rapid ejection of the ski is facilitated by the explosive chain reaction of the mixture (Fig. 3). Ejection can be initiated by the skier himself e.g. by pressing the sensors in the ski pole or glove or with teeth clenching if the sensor is placed in the mouth. The installed sensors on the skis can help the skier to turn on the system or. in some cases, they trigger the ski unblocking system themselves.

Za aktivno odpenjanje smuči skrbita dva sistema, sprednji aktivni sistem za horizontalni izmet smuči (sl. 2) in zadnji aktivni sistem za vertikalni izmet smuči (sl. 3). Sistema delujeta ločeno in jih lahko namestimo in uporabimo v kombinaciji oziroma ločeno vsakega posebej, odvisno od potreb in namena.Active skid release is provided by two systems, the front active horizontal ejection system (Fig. 2) and the rear active vertical ejection system (Fig. 3). The systems operate separately and can be installed and used in combination or separately individually, depending on needs and purpose.

Opis delovanja sprednjega aktivnega sistema za horizontalno odpenjanje smuči (3, sl. 2):Description of the operation of the front active system for horizontal ski lifting (3, Fig. 2):

Smučar oz. senzorji dajo električni signal, ki po žicah (15) aktivira linearni pogon (14). Linearni pogon v nekaj milisekundah potisne mehanizem (12), v katerem je čep (13). Čep vertikalno drsi v utoru mehanizma (11) in se vertikalno giblje proti smučarskemu čevlju. Po opravljeni določeni poti čepa se njegova višina dvigne toliko, da čep horizontalno zadane v zato pripravljeno steno luknje v čevlju. V nastalem kontaktu deluje horizontalna sila FH, ki v horizontalni smeri potisne čevelj iz vezi in tako odpne smučko s čevlja.Skier or. the sensors give an electrical signal that activates a linear actuator (14) through the wires (15). The linear actuator pushes the pin (13) mechanism (12) within a few milliseconds. The stud slides vertically into the groove of the mechanism (11) and moves vertically toward the ski boot. After completing a certain path of the shoe, its height is raised so that the shoe horizontally hits the hole in the shoe hole thus prepared. In the resulting contact, the horizontal force F H acts, pushing the shoe out of the tie in the horizontal direction, thus releasing the ski from the shoe.

Časovna karakteristika sile FH se določi z izbiro generatorja plina ali pirotehnične zmesi ter količino zmesi.The time characteristic of the force F H is determined by the choice of gas generator or pyrotechnic mixture and the amount of mixture.

Sile Fh, ki nastopajo med odpenjanjem smuči s čevlja, se ne prenašajo na smučarja.The forces F h that occur when the skis are released from the shoe are not transmitted to the skier.

Opis delovanja zadnjega aktivnega vertikalnega sistema za odpenjanje smuči (5, sl. 3):Description of the operation of the last active vertical ski release system (5, Fig. 3):

Linearni pogon je nameščen med smučko in smučarskimi čevlji. Smučar oz. senzorji dajo električni signal po žici (25), ki aktivira aktivator plina oz. pirotehnično zmes (24). Potisni bat (23) v nekaj milisekundah potisne čevelj v vertikalni smeri s silo Fv in tako odpne smučko in vezi s čevlja.A linear actuator is positioned between the ski and the ski boots. Skier or. the sensors give an electrical signal via a wire (25) which activates the gas activator or pyrotechnic mixture (24). The thrust piston (23) pushes the shoe vertically with force F into the milliseconds, releasing the ski and the shoe ties.

Časovna karakteristika sile Fvse določi z izbiro generatorja plina ali pirotehnične zmesi ter količino zmesi.The temporal characteristic of the force F v is determined by the choice of gas generator or pyrotechnic mixture and the amount of mixture.

Sile Fv, ki nastopajo za odpenjanje smuči s čevlja, se ne prenašajo na smučarja.The forces F v acting to release the ski from the shoe shall not be transferred to the skier.

Sistemi za aktivno odpiranje se namestijo na obe smučki med ali v vezi (sl. 1). Nameščeni sistemi se po potrebi sprožijo hkrati ali ločeno oz. v primeru, da sta nameščeni sprednja in zadnja naprava za izmet, lahko s časovnim zamikom.Active opening systems are mounted on both skis during or in conjunction (Fig. 1). Installed systems shall be triggered simultaneously or separately or separately. if the front and rear ejectors are installed, they can be delayed.

Aktivni sistem odpenjanja smuči ne vpliva na delovanje obstoječega klasičnega pasivnega sistema odpenjanja smuči, ga le dopolnjuje.An active ski release system does not affect the performance of the existing classic passive ski release system, it only complements it.

Potrebne aktivne sile FH in Fv izmeta smuči se ne prenašajo na smučarja, razen dinamične reakcijske sile, ki je odvisna od sunka sile, katere časovna karakteristika pa se lahko prilagaja kot funkcija odvisnosti velikosti in smeri sile od časa.The required active forces F H and F in the ejection skis are not transmitted to the skier, except for the dynamic reaction force, which depends on the shock of the force, whose temporal characteristic can be adjusted as a function of the dependence of the magnitude and direction of the force on time.

Prav tako oblika in majhna masa naprav ne vplivata na dinamiko smučanja in sistem ne spremeni karakteristik smučarske opreme. Dimenzije naprav ne presegajo dosedanjih gabaritov obstoječe smučarske opreme, skupna masa opreme se z namestitvijo naprav ne poveča v takšni meri, da bi lahko imela zaznaven vpliv na smučanje, saj so sestavni elementi izdelani iz lahkih kovinskih in nekovinskih materialov in so pretežno nameščeni v že obstoječe dele smučarske opreme.Also, the shape and low mass of the devices do not affect the dynamics of the ski and the system does not change the characteristics of the ski equipment. The dimensions of the devices do not exceed the existing dimensions of the existing ski equipment, the total weight of the equipment does not increase with the installation of the devices to such an extent that it could have a noticeable effect on skiing, since the constituent elements are made of light metal and non-metallic materials and are mostly installed in the existing ones. parts of ski equipment.
