Abstract

The subject of invention is an additional safety mechanism to safety ski bindings, which enables a reliable opening of the safety bindings even in cases of falls where the usual safety bindings would not operate reliably. The additional mechanism to safety ski bindings according to the invention is composed of a basic plate (1) which is fixed immovably to the tail or front part of the ski (A) and wears a rotationally bearing-supported frame (2) with a dent (2') on the one end, while on the other part of the plate (1) there is a movable plate (4)- fixed turnably by means of a pin (5) and a spring (6) - with a slightly upwards turned part (4') and a hook (4"). The release of the safety bindings is enabled by displacing the frame (2) which is attached to the heel or the front part of the safety ski bindings from the closed to the opened state.

Description

DODATNI VARNOSTNI MEHANIZEM PRI SMUČARSKIH VARNOSTNIH VEZEHADDITIONAL SAFETY MECHANISM AT SKI SECURITY TIES

Predmet izuma je dodatni varnostni mehanizem pri smučarskih is varnostnih vezeh, ki omogoča zanesljivo odpiranje varnostne vezi tudi pri padcih, pri katerih običajna varnostna vez ni zanesljivo delovala. Izum sodi v razred A 63 C 09/08 mednarodne patentne klasifikacije.The subject of the invention is an additional safety mechanism for ski and safety ties, which enables reliable opening of the safety connection even in the event of a fall in which the normal safety connection did not work reliably. The invention belongs to Class A 63 C 09/08 of the International Patent Classification.

Tehnični problem, ki ga predloženi izum uspešno rešuje, je konstrukcija in izvedba takšnega dodatnega varnostnega mehanizma, ki bo skupaj z znanimi izvedbami smučarskih varnostnih vezi, omogočal učinkovito delovanje običajne smučarske varnostne vezi tudi pri npr. takšnih padcih, ko smučar udari z zadnjim delom smuči ob tla in nekontrolirano rotira v eno smer, smučka pa zaradi udarca ob tla nogo zavije v nasprotno smer, kar je še posebno nevarno pri hitrem smučanju (smuk, veleslalom). Pri takšnih padcih dosedanje izvedbe smučarskih varnostnih vezi ne delujejo stoodstotno in zato lahko pride do poškodb, predvsem kolenskih vezi.A technical problem that is successfully solved by the present invention is the construction and implementation of such an additional safety mechanism, which, together with the known embodiments of the ski safety ties, will allow the effective functioning of the normal ski safety connection even in e.g. such falls when the skier strikes the back of the ski with the ground and rotates uncontrollably in one direction, and the ski turns the foot in the opposite direction due to the impact on the ground, which is especially dangerous in fast skiing (skiing, giant slalom). With such falls, the performances of the ski safety ties so far do not work 100% and therefore injuries, especially knee joints, can occur.

Znane izvedbe smučarskih varnostnih vezi so sestavljene iz prednjega dela - glave in zadnjega - petnega dela. Pri namestitvi smuči smučar pritrdi smučarski čevelj tako, da ga porine v prednji del smučarske varnostne vezi in glede na različne izvedbe mehanizma potisne petni del k smučki ali pa petni del dvigne ter tako učvrsti smučarski čevelj. Oba dela smučarske varnostne vezi, tako petni kot tudi prednji del, dopuščata možnost izpada smučarskega čevlja pri nenadni, dovolj veliki (velikost je možno nastaviti z regulirnim mehanizmom) prečni sili glede na smer vožnje, ki lahko nastane, npr. pri padcu smučarja. Zadnji, bolj poredko pa tudi prednji del, smučarske varnostne vezi, omogoča izpad smučarskega čevlja tudi pri dovolj veliki potezni sili (npr. pri padcu smučarja naprej).Known designs of ski safety ties consist of a front part - a head and a back - heel part. When installing the ski, the ski mounts the ski boot by pushing it into the front of the ski safety harness and, depending on the various implementations of the mechanism, pushes the heel to the ski or raises the heel to secure the ski boot. Both parts of the ski safety harness, both the heel and the front, allow the ski shoe to break in case of a sudden, large enough (size can be adjusted with the control mechanism) transverse force depending on the direction of travel that may occur, e.g. in the fall of a skier. The rear, and more rarely the front, ski safety ties, allows the ski boot to fail even with sufficient pulling force (eg when the skier falls forward).

is Problemi, ki nastanejo pri aktiviranju oz. neaktiviranju smučarske varnostni vezi, pa nastopijo pri silah, katerih komponente ne delujejo samo v omenjenih smereh in katerih velikosti niso tolikšne, da bi normalno nastavljena smučarska varnostna vez zanesljivo omogočila izpad smučarskega čevlja. Takšne sile lahko nastopijo predvsem pri hitrejšiis Problems encountered when activating or. However, when the ski safety link is not activated, forces occur whose forces do not act only in these directions and whose sizes are not such that a normally adjusted ski safety link can reliably allow the ski boot to fail. Such forces can occur primarily at a faster rate

2o vožnji, npr. na smučarskih tekmovanjih pri smuku ali veleslalomu, ko tekmovalec zaradi želje po čim hitrejšem smučanju pri izgubi ravnotežja nekontrolirano pade po smučišču in nekontrolirano rotira v eno smer, smučka pa zaradi udarca repa smuči ob podlago nogo zavije v nasprotno smer. Pri takšnem padcu sile, ki delujejo na sam čevelj nimajo takšne smeri in takšne jakosti, da bi običajno nastavljena smučarska varnostna vez zanesljivo delovala in omogočila izpad smučarskega čevlja, temveč se te sile prenesejo na koleno smučarja in tako pogosto pride do poškodb kolenskih vezi.2o runs, e.g. in ski or giant slalom competitions, when the competitor falls uncontrollably across the ski slope and rotates uncontrollably in one direction due to the desire to ski as fast as possible in the loss of balance and the ski turns its foot to the opposite direction due to the tail strike. In such a fall, the forces acting on the sole of the shoe do not have such a direction and strength that the normally adjusted ski safety link will reliably work and allow the ski boot to fail, but these forces are transferred to the skier's knee, which often results in damage to the knee ligaments.

Temu se je možno izogniti tudi tako, da je običajna smučarska varnostna vez nastavljena tako, da deluje že ob manjših prečnih silah, kar pa pri tekmovalnem smučanju ne pride v poštev, saj lahko podobne sile po smeri in jakosti nastopijo tudi pri hitrejšem in ostrem zavijanju okoli vratič.This can also be avoided by the fact that the normal ski safety harness is set to work even with smaller lateral forces, which is not relevant in competitive skiing, since similar forces can occur in both faster and steeper turns in direction and strength. around the door.

Dodatni varnostni mehanizem pri smučarskih varnostnih vezeh po izumu je sestavljen iz osnovne ploščice, ki je nepomično pritrjena na repni ali prednji del smuči in ki ima na enem koncu vrtljivo vležajen okvir z zobom, na drugem delu ploščice pa je zasukljivo preko nastavka in vzmeti is pritrjena gibljiva ploščica z rahlo poševno navzgor zavihanim delom in kljukico. Premaknitev okvirja, ki je z žico povezan s petnim ali prednjim delom smučarske varnostne vezi, iz napetega v sproženo stanje omogoči odprtje varnostne vezi.The additional safety mechanism of the ski safety ties according to the invention consists of a base plate which is fixedly fixed to the tail or front of the ski and which has a rotatably mounted frame with a tooth at one end and is rotatable over the attachment and spring and secured at the other part of the plate. moving tile with slightly sloping upward curved part and a hook. Moving the frame, which is connected to the heel or the front part of the ski safety harness by wire, from the tense to the triggered state allows the safety harness to be opened.

io Na slikah 1 in 2 je prikazan v shematskem aksonometričnem prikazu dodatni varnostni mehanizem pri smučarskih varnostnih vezeh po izumu v pogledu s strani in od zgoraj v sproženem položaju. Sestavljen je iz osnovne ploščice 1, ki je pritrjena na repni ali prednji del smuči A in ima na enem koncu vrtljivo vležajen okvir 2, ki ga v enem skrajnem položaju is držita vzmeti 3,3', na drugem delu ploščice 1 pa je zasukljivo pritrjena še gibljiva ploščica 4, katere rahlo poševno navzgor zavihan del 4' štrli izven repnega dela smuči. Gibljiva ploščica 4 je na osnovno ploščico 1 pritrjena preko nastavka 5 in vzmeti 6, ki omogoča premik ploščice 4 naprej in nazaj za določeno majhno razdaljo, kar omogoča vpetje in izpad zoba 2' izvedenega na okvirju 2 in kljukice 4 na gibljivi ploščici 4. Okvir 2 je s pomočjo žice 7 povezan s petnim delom smučarske varnostne vezi.io In Figures 1 and 2, an additional safety mechanism is shown in the schematic axonometric view of the ski safety ties of the invention in side and top view in the triggered position. It consists of a base plate 1 that is attached to the tail or front of the ski A and has a pivotally mounted frame 2 at one end, held by the springs 3,3 'at one extreme position and rotatably attached at the other end of the plate 1. a further movable pad 4 whose slightly obliquely upwardly curved portion 4 'extends beyond the tail portion of the ski. The movable plate 4 is fixed to the base plate 1 via a retainer 5 and a spring 6, which allows the plate 4 to move back and forth for a certain short distance, which allows the tooth 2 'to be engaged and dropped on the frame 2 and the hooks 4 on the flexible plate 4. Frame 2 is connected to the heel portion of the ski safety harness by means of wire 7.

Pri namestitvi smučarskega čevlja v smučarsko varnostno vez postavimo petni del le-te v položaj, ki ga kaže slika 3. Dodatni varnostni mehanizem je v zapetem položaju, kar pomeni, da sta kljukica 4 ploščice in zob 2' okvirja 2 v medsebojnem oprijemu tako da je okvir 2 pritisnjen ob površino osnovne ploščice 1, ploščica 4 pa je vzporedna z repnim delom smučke A, rahlo navzgor zavihan del 4' ploščice 4 pa štrli malenkostno (npr. cca 1 cm) izven dolžine smuči A.When mounting the ski boot in the ski safety harness, place the heel part of the ski boot in the position shown in Figure 3. The additional safety mechanism is in the locked position, which means that the hook 4 of the tile and the tooth 2 'of the frame 2 are in grip so that the frame 2 is pressed against the surface of base plate 1, plate 4 is parallel to the tail portion of ski A, and the slightly upwardly curved portion 4 'of plate 4 protrudes slightly (e.g., about 1 cm) beyond the length of ski A.

Če pride pri vožnji do nenadnega udarca repov smuči A ob podlago v taki smeri, da udari zavihan del 4' ploščice 4 ob podlago, se le-ta zaradi vrtljivega vpetja premakne in na ta način prideta kljukica 4 in zob 2' iz oprijema. Okvir 2 se zaradi delovanja vzmeti 3,3' premakne v lego, ki jo io prikazujeta sliki 5 in 6 in s potegom žice 7 odpre petni del smučarske varnostne vezi in s tem sprosti smučarski čevelj.If, when driving, the tails of ski A are suddenly hit by the ground in such a way that it strikes a curved portion 4 'of the tile 4 against the ground, it is displaced by the rotating clamp and thus a hook 4 and a tooth 2' out of the grip. Due to the operation of the spring 3.3 ', the frame 2 is shifted to the position shown in Figures 5 and 6 by pulling the wire 7 to open the fifth part of the ski safety link, thus releasing the ski boot.

Dodatni varnostni mehanizem pri smučarskih varnostnih vezeh, katerega delovanje je opisano pri izvedbi in delovanju na petni del smučarske varnostne vezi je možno z določenimi modifikacijami uporabiti is tudi na prednjem delu smuči pri sami krivini, podobno kot dodatek za povečanje krivine, le da je dodatni varnostni mehanizem pritrjen na nasprotni strani dodatka za povečanje krivine. V primeru namestitve na prednji del smuči je jeziček varovala nameščen na desni strani krivine leve smučke in na levi strani krivine desne smučke ter se sproži pri nepravilni vožnji ob palici (npr. pri hitrejših disciplinah kot sta super veleslalom in veleslalomu) in morebitnem posledičnem padcu.An additional safety mechanism for ski safety ties, the operation of which is described in the construction and operation of the fifth part of the ski safety connection, can be used with certain modifications also on the front of the ski at the curve itself, much like an accessory to increase the curve, but it is an additional safety feature. a mechanism attached to the opposite side of the bend enhancement accessory. When mounted on the front of the ski, the guard tab is located on the right side of the left ski curve and on the left side of the right ski curve, and is triggered by improper running on a stick (eg in faster disciplines such as super giant slalom and giant slalom) and any subsequent fall.

Dodatni varnostni mehanizem pri smučarskih varnostnih vezeh po izumu je glede na opisani izvedbeni primer možno izvesti kot je opisano, zaradi zaščite pred vremenskimi vplivi (zmrzal, vdor snega) pa ga je potrebno dodatno zaščititi z ohišjem in primerno zaščititi tudi žico 7.According to the embodiment described, the additional safety mechanism for the ski safety ties according to the invention can be carried out as described, and in order to be protected from the weather (frost, snow intrusion), it must be additionally protected by a housing and also properly protected by a wire 7.
