CLASS 77 b: 11/24 INT CLASS A 63 c PATENT PERIOD FROM 9 JUNE 1958 GRANTED ON 27 JULY 1961 PUBLISHED ON 3 OCTOBER 1961 Ans. 5478/1958 on 9/6 1958 Herewith a drawing PS () STEVE, OSLO, NORWAY Ski pole with pretzel Priority requested from 22 full 1957 (Norway) The present invention relates to a ski pole with pretzel, and the invention has for its purpose to create a pretzel, which offers several benefits compared to previously known types of pretzels for ski poles. A fault with the usual pretzels has been that these, which had the shape of an open wheel with spokes, easily got stuck in trousers, bushes and the like. It has therefore previously been proposed to present the pretzels as ski poles largely as a whole piece of veneer with an inverted shell shape. However, such "whole" ski pole pretzels have had the error of being inclined to be cluttered with ice and snow coating, which makes them heavy and impractical.

Enligt uppfinningen foreslar man emellertid en kringla till en skidstav, vars egenart be-star i kombinationen av foljande sardrag, namligen att kringlan i sin helhet är framstalld som en omvant skalformad kropp med obruten yta bortsett Iran ett foretradesvis centralt anordnat hal, vars ka.nt direkt omsinter skidstaven, och att kringlan i sin helhet ar framstalld av elastiskt material. According to the invention, however, a pretzel is proposed for a ski pole, the uniqueness of which consists in the combination of the following features, namely that the pretzel as a whole is formed as an inverted shell-shaped body with an unbroken surface apart from Iran a preferably centrally arranged hall, the directly surrounds the ski pole, and that the pretzel as a whole is made of elastic material.

Genom att kringlan framstalles av elastiskt material, samtidigt med att den meddelas skalform, uppnar man de fordelar, som uppkomma pa grund av skalformen, namligen att kringlan icke kan hanga sig fast, samtidigt som elasticiteten i materialet forhindrar, att is och sno fastna vid eller lagra sig ovanpa. kringlan. Denna kommer namligen under anvandningen att standigt vara utsatt for deformationer, varigenom envar begynnande iseller snobelaggning omedelbart kommer att brytas solider och falla ay. By making the pretzel of elastic material, at the same time as it is communicated in the form of a shell, the advantages which arise due to the shell shape are achieved, namely that the pretzel cannot stick, while the elasticity of the material prevents ice and snow from sticking to or store on top. kringlan. This is because during use it will be constantly exposed to deformations, whereby any incipient ice or snobbery will immediately break solid and fall ay.

Genom att kringlan utbildas pa det angivna sattet blir aven dess fastande vid staven mycket enkelt. Detta kan exempelvis ske enbart genom att man ph hada sidor om det centrala hal, genom -vilket staven dr fOrd, anbringar en tall anslutande gumnairing eller liknande eller nagot annat slag av stoppanordning. By training the pretzel in the specified way, its fastening to the rod also becomes very easy. This can be done, for example, only by having sides of the central hall, through which the rod runs, attach a pine connecting gumnairing or the like or some other kind of stopping device.

En sadan enkel fastning av kringlan vid skidstaven mOjliggor vidare den fordelen, att man kan forandra dess placering pa skidstaven. Detta kan ofta vara onskvart, om man viii anpassa det djup, med vilken skidstavens nedanfor kringlan liggande del skjuter ned i snon, efter de vid vart sarskilt tillfalle radande forhallandena. Vid en sadan pakrympning, som ovan beskrivits kan en sadan efterstallning pa ett enkelt satt aga rum, om sa skulle vara onskvart, sarskilt om man anbragt enkla stopporgan pa oversidan av kringinn. Till ytterligare belysning av uppfinningen skall nu hanvisas till ett utforingsexempel, som visas i sektion pa ritningen, dar fig. 1 visar en kringla till en skidstav enligt uppfinningen, sedd nedanifran, och fig. 2 visar en sektion genom samma kringla. ritningen är den omvant skalformadc kringlan 1 till skidstaven utbildad exempelvis av nagot lampligt konstplastmaterial. Kringlan har ett nagot tjockare yttre kantparti 3 och ett centralt hal 2 for genomfOring av skidstaven. Detta hal är jamval foretradesvis forsett med en kantforstarkning 3'. Pa bagge sidor om genomforingen aro tatt omslutande gummiringar anbragta. De ha till andamM att hana kringlan pa ratt plats pa skidstaven. Such a simple attachment of the pretzel to the ski pole further enables the advantage that one can change its location on the ski pole. This can often be unfortunate, if one wants to adjust the depth with which the part of the ski pole below the pretzel shoots down into the snow, according to the radiating conditions at each particular occasion. In the case of such a package shrinkage, as described above, such a substructure in a simple set room can, if so, be unobtrusive, especially if simple stop means have been arranged on the upper side of the circumference. To further illustrate the invention, reference will now be made to an embodiment shown in section of the drawing, in which Fig. 1 shows a pretzel of a ski pole according to the invention, seen from below, and Fig. 2 shows a section through the same pretzel. the drawing is the inverted shell-shaped pretzel 1 of the ski pole formed, for example, of some suitable plastic material. The pretzel has a slightly thicker outer edge portion 3 and a central hall 2 for the passage of the ski pole. This haul is preferably provided with an edge reinforcement 3 '. Enclosed rubber rings are placed on the rear sides of the bushing. They have to breathe to keep the pretzel in the right place on the ski pole.

Enligt en annan utforingsform utgOres det ovre stopporganet av en krage, som är utbildad .stavens dubbhylsas Ovre kant. According to another embodiment, the upper stop member is constituted by a collar which is formed by the upper edge of the double sleeve of the rod.

Aven om ritningen endast visar en enda utforingsform, inser fackmannen omedelbart, att uppfinningen icke ãr begransad till denna. mom uppfinningens ram kunna saledes en hel del modifikationer inrymmas. Nar har talas om »omvand skalform», sd skall detta uttryck forstas soul omfattande envar form for en kringla till skidstavar, som har en Reda vand konkavitet och en uppat vand konvexitet, eller som man plagar ultrycka det, som dr av klockform. Although the drawing shows only a single embodiment, those skilled in the art will immediately recognize that the invention is not limited thereto. According to the scope of the invention, a lot of modifications can thus be accommodated. When there has been talk of "inverted shell form," this expression is to be understood as encompassing any form of a pretzel for ski poles, which has a red water concavity and an raised water convexity, or which one bothers to express it, as dr of bell shape.

Uttrycket »elastiskt material>> i detta sammanhang skall likaledes omfatta ett vart material, som dr sa eftergivande eller elastiskt, att kringlan under anvandning utsattes for formf8randringar, vilka dro tillrackliga for att forhindra is- och snobelaggning. Ett for — — andamalet lampligt material bestar till exempel av atskilliga slag av konstplast eller nylon, men aver' andra elastiska material kunna komma ifraga. The term "elastic material" in this context is likewise intended to include any material which is so resilient or elastic that during use the pretzel is subjected to deformations which are sufficient to prevent ice and snobbery. A pre-formed lamp material consists, for example, of several kinds of synthetic plastic or nylon, but other elastic materials may be considered.

Man inser, att kringlan icke nadvandigtvis made vara helt tat eller sammanhangande, i det aft fina perforeringar kunna anvandas, sa lange dessa icke arc sâ stora, att de kunna astadkomma kringlans fasthangande i buskar, grenar och dylikt. It is realized that the pretzel is not necessarily made to be completely dense or coherent, since fine perforations can be used, as long as these are not so large that they can cause the pretzel to get stuck in bushes, branches and the like.

Icke heller behover halet for genomforande av skidstaven vara anordnat centralt i kringlan eller lopa vinkelratt mot dennas huvudplan. Nor does the tail for carrying the ski pole need to be arranged centrally in the pretzel or run perpendicular to its main plane.

Claims
