Abstract

Anordning ved barmarkskiDevice for bare field skiing

Description

Oppfinnelsen angår en anordning ved en hjul- eller rullunderstøttet barmarkski, hvilken anordning er beregnet å bremse skiens rulling/glidning bakover. The invention relates to a device for a wheel- or roller-supported bare-country ski, which device is intended to slow the ski's rolling/sliding backwards.

For å muliggjøre rulleskigåing på glatt underlag,To enable roller skiing on smooth surfaces,

må rulleskien være innrettet slik at den hindrer en bakoverglidning i forhold til underlaget dersom dette utgjøres av is, snø eller et annet glatt underlag. the roller ski must be arranged so that it prevents a backward slide in relation to the surface if this consists of ice, snow or another slippery surface.

Det er hittil ikke blitt foreslått noen effektivean-ordninger som hindrer en slik bakoverglidning. Det finnes riktignok frihjulskoplinger som er anordnet ved hjulunder-støttede barmarkski , men disse hindrer ikke at hjulet glir bakover når underlaget er glatt. Disse frihjulskoplinger er oftest.innebygget i ett eller flere hjulnav og er meget føl-somme for ytre forstyrrelser i form av is, salt eller grus som finner veien inn i f rih julsmekanisrnen og der lett gir opphav til forstyrrelser. So far, no effective measures have been proposed to prevent such a backward slide. It is true that there are freewheel couplings that are fitted to wheel-supported bare-ground skis, but these do not prevent the wheel from sliding backwards when the surface is smooth. These freewheel couplings are most often built into one or more wheel hubs and are very sensitive to external disturbances in the form of ice, salt or gravel that find their way into the freewheel mechanism and easily cause disturbances.

Formålet med oppfinnelsen er å tilveiebringe en anordning som med sikkerhet hindrer skiens glidning bakover, selv når skien benyttes på glatt underlag. The purpose of the invention is to provide a device which reliably prevents the ski from sliding backwards, even when the ski is used on smooth ground.

Dette formål oppnås ifølge oppfinnelsen ved at anordningen har fått de i patentkravene angitte kjennetegn. This purpose is achieved according to the invention in that the device has been given the characteristics stated in the patent claims.

Oppfinnelsen skal beskrives nærmere i det følgende under henvisning til tegningen hvis ene figur viser en del av en hjulunderstøttet ski sett fra siden og forsynt med en anordning ifølge oppfinnelsen. The invention shall be described in more detail in the following with reference to the drawing, one figure of which shows a part of a wheel-supported ski seen from the side and provided with a device according to the invention.

Skien 1 har et hjul 2 bak hvilket anordningen ifølge oppfinnelsen er plassert. Skiens rulleretninq er angitt ved hjelp av en pil A. The ski 1 has a wheel 2 behind which the device according to the invention is placed. The ski's rolling direction is indicated by an arrow A.

Anordningen omfatter et pendellegeme 3 som ved 5 ved hjelp av et festeorgan 6 er festet til skiens underside. Legemet 3 er med heltrukne linjer vist i upåvirket stilling, dvs. når skien ikke er i kontakt med underlaget 10 .(stilling a). Anordningen ifølge oppfinnelsen er fremstilt av et elastisk materiale, og et utvidet endeparti 7 av legemet kan nå- ned til underlaget 10 under anvendelse av skien. Med strekprikkede linjer (stilling b) er vist den stilling som legemet 3 inntar ved skiens 1 rulling fremover i pilens A retning. Ved skiens 1 bakoverglidning i forhold til underlaget 10 forflyttes pen dellegemet 3 til en stilling der i hovedsaken legemets 3 endeparti 7 er inneklemt mellom underlaget 10 og hjulet 2, slik som vist med strektegnede linjer (stilling c). På denne måte oppnås en effektiv bremsing av skien mot glidning bakover da den fremre del 0 av pendellegemets .3 utvidede parti 7 vil bli klemt mellom skiens hjul 2 og underlaget 10. For å ytterligere øke anordningens bakoverbremsende evne, er friksjonsøkende organer 11 hensiktsmessig anordnet ved det bakre parti 9 av legemets 3 utvidede parti 7. The device comprises a pendulum body 3 which, at 5, is attached to the underside of the ski by means of a fastening means 6. The body 3 is shown with solid lines in an unaffected position, i.e. when the ski is not in contact with the surface 10 (position a). The device according to the invention is made of an elastic material, and an extended end part 7 of the body can reach down to the base 10 when using the ski. Dotted lines (position b) show the position that the body 3 takes when the ski 1 rolls forward in the direction of the arrow A. When the ski 1 slides backwards in relation to the base 10, the pen part body 3 is moved to a position where, in the main, the end part 7 of the body 3 is sandwiched between the base 10 and the wheel 2, as shown with dashed lines (position c). In this way, an effective braking of the ski against sliding backwards is achieved as the front part 0 of the pendulum body's .3 extended part 7 will be squeezed between the ski's wheel 2 and the base 10. To further increase the device's backward braking ability, friction-increasing members 11 are suitably arranged at the rear part 9 of the body 3 extended part 7.

Pendellegemets 3 innfestingsstilling på skien 1 kan være regulerbart anordnet ved utnyttelse av borttagbare brik-ker A mellom legemet og skien. Denne innstilling av legemets stilling i forhold til underlaget er beregnet å utnyttes når stilriktig skitrening skal oppnås under gåing på barmarkskiene. For å trene stilriktig gåing i en stigning, er det således meget viktig'at en nedadrettet kraft utøves på skiens spenn under hvilket et klebende belegg normalt er anordnet ved kon-vensjonelle ski. Ved å anordne pendellegemet noe over underlaget, kreves således en nedtrykking av rulleskiens spenn for at pendellegemets 3 utvidede parti 7 skal komme i kontakt med underlaget og derved utøve en bremsende virkning mot skiens glidning bakover. Når pendellegemets 3 utvidede parti er kom-met i inngrep mellom hjulet 2 og underlaget 10, opprettholdes bremsevirkningen selv om trykket på rulleskiens spenn avtar. The attachment position of the pendulum body 3 on the ski 1 can be adjusted by using removable pieces A between the body and the ski. This setting of the body's position in relation to the ground is intended to be used when proper ski training is to be achieved while walking on bare-ground skis. In order to practice stylish walking on a slope, it is thus very important that a downward force is exerted on the ski's span under which an adhesive coating is normally arranged in conventional skis. By arranging the pendulum body somewhat above the ground, the roller ski's span is thus required to be depressed so that the extended part 7 of the pendulum body 3 comes into contact with the ground and thereby exerts a braking effect against the ski sliding backwards. When the extended part of the pendulum body 3 is engaged between the wheel 2 and the base 10, the braking effect is maintained even if the pressure on the roller ski's span decreases.

Den bremsende virkning som oppnås ved hjelp av anordningen ifølge den foreliggende oppfinnelse, tilveiebringes således dels ved at hjulets rulling bakover hindres ved kontakt med pendellegemet 3 som derved samtidig klemmes mot underlaget 10, og dels ved at hjulet 2 hindres fra å gli bakover på grunn av den økede friksjon mellom på den ene side underlaget 10 og pendellegemet 3 og på den annen side hjulet 2 og pendellegemet 3. Ved iset underlag er de friksjonsøkende organer 11 beregnet å virke på den måte at de med stor kraft griper inn i underlaget 10 når skien 1 har tendens til å gli bakover, eventuelt med låst hjul 2. The braking effect which is achieved by means of the device according to the present invention is thus provided partly by the wheel's rolling backwards being prevented by contact with the pendulum body 3 which is thereby simultaneously clamped against the base 10, and partly by the wheel 2 being prevented from sliding backwards due to the increased friction between on the one hand the surface 10 and the pendulum body 3 and on the other hand the wheel 2 and the pendulum body 3. In the case of an icy surface, the friction-increasing organs 11 are intended to act in such a way that they engage the surface 10 with great force when the ski 1 tends to slide backwards, possibly with locked wheel 2.

Anordningen ifølge oppfinnelsen kan ha en bredde som svarer til skiens eller hjulets bredde. Den kan også være oppdelt i flere innbyrdes svingbare legemer, eller den trenger bare bestå av et legeme som samvirker med en begrenset del av hjulets periferi bredde. The device according to the invention can have a width that corresponds to the width of the ski or the wheel. It can also be divided into several mutually pivotable bodies, or it only needs to consist of a body that interacts with a limited part of the wheel's peripheral width.

Oppfinnelsen er ikke begrenset til det viste ut-førelseseksempel, men modifikasjoner kan gjøres innenfor rammen av de etterfølgende patentkrav. The invention is not limited to the embodiment shown, but modifications can be made within the scope of the subsequent patent claims.
