Description

Uppfinnare: F Kastl Prioritetbegard fran den februari 1959 (Osterrike) FOreliggande uppfinning avser en anordning vid en sakerhetsskidbindning med minst en pa skidan medelst en lfingsgaende slitsstyrning och lagertapp vridbart och i lfingdriktningen forskjutbart lagrad back med framat kilformigt konvergerande sidoytor, som fOretradesvis sammanlopa i en avrundad frfimre kant, varvid backen i normalt aklage stoder mot ett stopp och fasthalles av fitminstone en mellan slitsstyrningen och stoppet anbragt sparranordning. Inventor: F Kastl Priority request from February 1959 (Austria) The present invention relates to a device for a safety ski binding with at least one on the ski by means of a sliding guide and bearing pin rotatably and in the sliding direction slidably mounted jaw with forward wedge-shaped converging side surfaces. front edge, the jaw in normal inclination facing a stop and being held by fit at least one spar device arranged between the slot guide and the stop.

Vhf en kand sfikerhetsskidbindning av detla slag fasthalles backen pa skidan i langdled ddrigenom, att pa backens undersida är anordnad en vinkelratt mot skidan nedskjutande tapp, som i backens normallfige sti3- der mot ett pa skidan fast anslag, varvid delta anslag uppbares foretradesvis av en pa skidan fastskruvad platta. Hfirvid utgoras dessa anslag av inslagna stift, nitar eller uppb8jda metalldelar. Olagenheten med denna konstruktion bestar M. a. ddri, att dessa anslagselement ofta icke tala upptrfidande pakfinningar, och att mellan backens undersida och skidans oversida finnes ett mellanrum, i vilket sdrskilt is kan satta sig fast, varigenom sfikerhetsbindningens funktion kan aventyras. Vid'are har vid denna kfinda bin:dning backen en alltfor ringa forskjutningsmojlighet i lfingdriktningen. Detta dr en. tungt magande olagenhet. Det har nfimligen visat sig, att sarskilt yid kullerbyttor, varvid den farliga stortkraften an riktad ungeffir i riktning .skospets-skidspets sakerheten mot utlosning är otillracklig yid sakerhetsbindningar med felande eller alltfor ringa forskjutbarhet i langdled. In the case of a known safety ski binding of this kind, the slope of the ski is maintained longitudinally in that a pin projecting perpendicularly to the ski is arranged on the underside of the slope, which in the normal slope of the slope faces a fixed stop on the ski. ski screwed plate. For this purpose, these stops consist of wrapped pins, rivets or bent metal parts. The disadvantage of this construction consists, among other things, in the fact that these abutment elements often do not involve striking packing findings, and that there is a gap between the underside of the slope and the upper side of the ski, in which special ice can get stuck, whereby the function of safety binding can be compromised. Furthermore, with this fine bonding, the slope has too little displacement in the direction of movement. This dr one. heavy stomach upset. It has recently been found that especially in somersaults, whereby the dangerous large force directed approximately in the direction of the tip of the tip of the skis is insufficient against ejection, there are insufficient bonds with faulty or too little long-distance displaceability.

Genom foreliggande uppfinning undvikas dessa olagenheter. Detta ernas i huvudsak dirigenom, att backens framre kant stoder mot stoppet, exempelvis mot ett cylindriskt huvud pa en skruv, nit e. d., som fir insatt vertikalt i framre finden ay en grundplatta fOr backen, varvid backens sidoytor aro utformade som yid utlosning mot stoppet glidbara avlankningsytor, och att pa i och for sig kant satt den i backen anordnade slitsens langd motsvarar minst dubbla diameter. for hela den fastsittande i slitsen anordnade lagertappen. The present invention avoids these imperfections. This is mainly due to the fact that the front edge of the jaw rests against the stop, for example against a cylindrical head on a screw, rivet, which is inserted vertically in the front fin on a base plate for the jaw, the side surfaces of the jaw being designed as sliding towards the stop slidable deflection surfaces, and that on the per se edge sat the length of the slot arranged in the hill corresponds to at least double the diameter. for the entire bearing pin arranged in the slot.

Den enligt uppfinningen fOreslagna fasthallningen av backen i langdled ar mekaniskt och ur framstallningssynpunkt overldgsen det kanda utfOrandet, ear backen utan nagot som heist mellanelement stoder direkt mot stoppet. Detta utforande mojliggor en plan anliggning av backen mot dennas grundplatta, varigenom sfirskilt en stiirande isbildning mellan backen och grundplattan i avsevfird grad undvikes. De pa sidorna anordnade avlankningsytornas samverkan med stoppet medftir sarskilt i forening med backens stora fOrskjutningsmOjlighet I lfingdled en sarskilt gynnsam utkisningskarakteristik. The longitudinal retaining of the slope proposed according to the invention is mechanical and, from a manufacturing point of view, superior to the known design, since the slope without anything like an intermediate element stands directly against the stop. This design enables a planar abutment of the slope against its base plate, whereby a steered ice formation between the hill and the base plate is largely avoided to a considerable extent. The interaction of the deflection surfaces arranged on the sides with the stop entails, in particular in conjunction with the large displacement possibility of the slope, a particularly favorable outcroping characteristic.

Enligt en ytterligare utformning av uppfinningen dr i backens bakre del anordnad en i hoj died stallbar sulhallare. Dfirigenom kan backen sa anpassas till varje sko, att en sarskilt god, formfast forbindning erhalles mellan sko och back. According to a further embodiment of the invention, a height-adjustable sole holder is arranged in the rear part of the hill. As a result, the heel can be adapted to each shoe in such a way that a particularly good, dimensionally stable connection is obtained between the shoe and the heel.

Ett ytterligare vasentligt kfinnetecken for uppfinningen bestir ddri, att sulhallaren fir horisontellt svangbar en liten vinkel. Darigenom trygga:s a ena sidan en fullgod, formfast forbindning mellan sko och back yid normal akning, och a andra sidan ernas, att sa snart bindningen utiliser undvikes saliert sadana extra spanningar, som upptrada vid en fastsittande sulhallare. A further essential feature of the invention is that the sole holder is pivotable horizontally at a small angle. This ensures, on the one hand, a good, stable connection between the shoe and the back during normal handling, and on the other hand, that as soon as the binding utilizes, such extra stresses are avoided as would occur with a stuck sole holder.

En sasom exempel vald utforingsform av 2-- — en bindning enligt uppfinningen at visad pa bifogade ritning. An exemplary embodiment of a bond according to the invention is shown as shown in the accompanying drawing.

Den pa en skida monterade bindningen visas schematiskt fran sidan i fig. 1. Fig. 2 ar en planvy. Fig. 3 ar en vertikal sektion langs mittlinjeni fig. 2. The binding mounted on a ski is shown schematically from the side in Fig. 1. Fig. 2 is a plan view. Fig. 3 is a vertical section along the center line of Fig. 2.

Pa skidan 1 ar en grundplatta 2 fast med skruvar 3. En ph grundplattan 2 fast farank- rad, vertikalt staende lagertapp 4 gar igenom en avlang styrning 5 i en back 6, sá att denna ar lagrad saval vridbar som forskjutbar I langdled relativt skidan 1 respektive grundplattan 2. Langden p. styrningen 5 motsvaTar enligt uppfinningen minst den dubbla diametern pa lagertappen 4. On the sheath 1 a base plate 2 is fixed with screws 3. A ph base plate 2 fixedly anchored, vertically standing bearing pin 4 passes through an elongate guide 5 in a jaw 6, so that this bearing is rotatable and displaceable longitudinally relative to the sheath 1 respectively the base plate 2. According to the invention, the length of the guide 5 corresponds to at least twice the diameter of the bearing pin 4.

Tappen 4 har pa sin owe ande en ansats 7, som samverkar med en styrning 8 i backen och sakrar denna mot lyftning i vertikalled. For att fa en enkel montering ãr den ovre ansatsen 7 lampligen bildad av en i lagertappen axiellt inskruvad skruv 19. Lampligen har lagertappen 4 aven pa det stalle dar den utgar ur grundplattan en ansats 20, som i sin tar samverkar med en styrning 21 pa backen 6. Den avlanga styrningen och lagertappen aro medelst en tackplatta 9, ãr fast pa backen 6 med skruvar 10, skyddade mot intrangande snö och is saint andra faroreningar. The pin 4 has on its head a shoulder 7, which cooperates with a guide 8 in the hill and secures it against lifting in the vertical direction. In order to obtain a simple mounting, the upper shoulder 7 is suitably formed by a screw 19 which is axially screwed into the bearing pin. Luckily, the bearing pin 4 also has a shoulder 20 at the place where it exits the base plate, which in turn cooperates with a guide 21 on the jaw. 6. The elongate guide and bearing journal are by means of a roof plate 9, fixed to the hill 6 with screws 10, protected against penetrating snow and ice as well as other hazardous impurities.

Backens 6 framre del liar enligt uppfinningen ungefar kilformigt framat sammanlOpan- de6c, 6d och staler med sin framre, sarskilt spetsiga ande direkt mot ett i grundplattan 2 anordnat stopp 18. I _backens 6 framre del, enligt uppfinningen maim den avlanga styrningen 5 och stoppet 18, Or anbragt en sparranordning 11. Denna bestar foretradesvis av en kula 12, som av en fjader 13 Mlles pressad i en urtagning 14 grundplattan 2. Fjaderns 13 presskraft ,och darmed backens 6 installning (utlasning) _pa. en storre eller mindre omstallningskraft (vridmoment) kan forandras med hjalp av en .skruv 15. According to the invention, the front part of the jaw 6 is approximately wedge-shaped forwardly connecting 6c and 6d and steel with its front, particularly pointed spirit directly against a stop 18 arranged in the base plate 2. In the front part of the jaw 6, according to the invention, the elongate guide 5 and the stop 18 A sparing device 11 is provided. This preferably consists of a ball 12, which is pressed by a spring 13 into a recess 14 of the base plate 2. The compressive force of the spring 13, and thus the installation (discharge) of the jaw 6. a greater or lesser shifting force (torque) can be changed with the help of a screw 15.

For att hindra att stallskruven 15 skruvas ut for langt och darmed riskerar att forloras, finns enligt en ytterligare utforingsform av uppfinningen ett anslag 24, som lampligen uppbares av tackplattan 9. In order to prevent the stable screw 15 from being unscrewed too far and thereby risking being lost, according to a further embodiment of the invention there is a stop 24, which is suitably supported by the roof plate 9.

PA backens 6 bakre ande Or anordnad en sulhallare 16. Denna Or enligt uppfinningen stallbar i yertikalled medelst en i backen 6 lagrad skruv 17. The rear end Or of the PA jaw 6 is provided with a sole holder 16. This Or according to the invention can be adjusted vertically by means of a screw 17 mounted in the jaw 6.

En sarskilt lamplig utforingsform av uppfinningen bestar vidare dad, att sulhallaren 16 dessutom Or svangbar horisontellt en liten -vinkel, varvid lampligen anslagsytor 6a, 6b begransa denna vinkel. A particularly suitable embodiment of the invention further comprises that the sole holder 16 is also pivotable horizontally a small angle, whereby abutment surfaces 6a, 6b define this angle.

Den i fig. 2 och 3 med 26 antydda skon lastes i bindningen pA sa satt, att den medelst en kabel 28 (fig. 2) med den frantre kanten av sulan 27 pressas mot en svagt lutande yta 22 pa sulhallaren 16, vilken yta: nara sina sidokanter har en foretradesvis parallellt med des sa kanter lapande vulst 23 pa hada sidor. Over skosulans 27 ovre framre kant griper en till- narmelsevis horisontell flik 25 pa sulhallaren 16. Sasom redan namnts ernas genom den begransat svangbara sulhallaren A ena sidan en fullgod, formfast forbindning mellan sko 26 och back 6 vid normal akning, och a andra sidan ernas, att sa snart bindningen laser ut undvikas sakert de extra spanningar, som upptrada vid en fast sittande sulhallare: DA backen b5rjar sin svangrarelse skulle namligen pA grund av den pa iimse sidor om mitt- axelnbakat sig strackande stadytan 22 pa sulhallaren upspta en markbar Okning av skospetsens avstand fran skidspetsen och darmed en farskjutning bakat av skon och dared foten, vilket i stallet f8r att minska inspanningskraften skulle aka den. Detta undvikes genom den enligt uppfinningen majliggj orda kompensationen av bakatforskjutningen pa grund av ytans 22 form genom en framatsva.ngning av ifragavarande vinge pa sulhallaren. A andra sidan anpassar sig ocksa den begransat svangbara sulhallaren battre till de oundvikliga oregelbundenheterna: pa skospetsen. Sakerhetsbindningen verkar pa foljande salt: Om en mellan skon 26 och skidan 1 upptradande tvarkraft (yridmoment) overstiger det medelst sparranordningen 11 installda vardet, sa loser sparranordningen ut och backen 6 glider framat farbi stoppet 18, sarskilt under samtidig vridning kring lagertappen 4. Detta forlopp medfor ett sakert losgorande av skon Iran bindningen yid farliga pakanningar. The shoe indicated in Figs. 2 and 3 by 26 is loaded into the binding pA in such a way that it is pressed by means of a cable 28 (Fig. 2) with the front edge of the sole 27 against a slightly inclined surface 22 on the sole holder 16, which surface: Near its side edges, a bead 23 preferably on the sides has a bead running parallel to its edges. Above the upper front edge of the shoe sole 27, an approximately horizontal flap 25 engages on the sole holder 16. As already mentioned, through the limited pivotable sole holder A on the one hand a good, dimensional connection between shoe 26 and back 6 during normal riding, and on the other side , that as soon as the binding laser out, the extra stresses which occur at a fixed sole holder are certainly avoided: DA the hill begins its pregnancy would, namely due to the on some sides of the mid-shoulder-backed stretching surface 22 on the sole holder, a noticeable increase in the distance of the shoe tip from the tip of the ski and thus a parachute baked by the shoe and dared the foot, which instead of reducing the exertion force would drive it. This is avoided by the compensation of the rearward displacement made possible according to the invention due to the shape of the surface 22 by a forward oscillation of the wing in question on the sole holder. On the other hand, the limited pivoting sole holder also adapts better to the inevitable irregularities: on the tip of the shoe. The safety binding acts on the following salt: If a transverse force (torque) occurring between the shoe 26 and the ski 1 exceeds the value set by the spar device 11, the spar device releases and the jaw 6 slides forward past the stop 18, especially while simultaneously rotating around the bearing pin 4. This process entails a safe detachment of the shoe Iran binding yid dangerous pakannings.

Uppfinningen Or icke begransad till den visade utforingsformen. Exempelvis yore Oven ett sadant utforande tankbart, vid vilket i grundplattan anordnade upplajningar samverka med pa backens undersida anordnade styrningar..Givetvis Jigger ockso. ett platsbyte av de enskilda delarna inom uppfinningens ram, t. ex. anordnandet av lagertappen i backen och styrningen i backens grundplatta. The invention is not limited to the embodiment shown. For example, there is also such a design conceivable, in which uprights arranged in the base plate cooperate with guides arranged on the underside of the slope. Of course, Jigger also. a change of location of the individual parts within the scope of the invention, e.g. the arrangement of the bearing pin in the jaw and the guide in the base plate of the jaw.
