Description
Fottøy for svømmere. Footwear for swimmers.
Det er allerede kjent fottoy for svbmmere forsynt med en svomme-finne som har form av et palmeblad som forlenger foten fremover og som strekker seg horisontalt i hbyde med fottoyets underste flate. Imidlertid er disse kjente svommefotter ikke til noen hjelp og er tvert imot hemmende for svbmmere som av en eller annen grunn crawler. Ved crawling kan i virkeligheten den naturlige bevegelse av benene ikke utfores normalt hvis foten er forlenget med en svomme-finne av den ovennevnte kjente art. There are already known foot toys for swimmers provided with a swimming fin which has the shape of a palm leaf which extends the foot forward and which extends horizontally at height with the bottom surface of the foot toy. However, these known swimmer's feet are of no help and, on the contrary, are a hindrance to swimmers who for some reason crawl. When crawling, in reality, the natural movement of the legs cannot be carried out normally if the foot is extended with a swimming fin of the above-mentioned known kind.
Det er også kjent et fottby for svbmmere hvor det er anordnet en skjellformet finne som strekker seg utenfor svbmmefottoyets There is also known a foot city for swbmmers where a shell-shaped fin is arranged that extends outside the swbmme fotto's

Imidlertid har det vist seg at det er av betydning for en svommer å holde seg ved vannets overflate ved hjelp av naturlige benbevegelser. Organer av denne art er f.eks. særlig nyttige ved livredningsoperasjoner eller når svbmmeren må kunne komme fremover i vann ved transport av en last. eller når de er hindret i sine be- However, it has been shown that it is important for a swimmer to stay at the surface of the water using natural leg movements. Organs of this kind are e.g. particularly useful in life-saving operations or when the swimmer must be able to move forward in water when transporting a load. or when they are hindered in their be-

vegelser. vexations.
De kan likeledes være nyttige for svbmmere som utover undervannsdykking for ovelsesformål ved bestemte operasjoner. They can also be useful for swimmers who, in addition to underwater diving, for training purposes in certain operations.
Det er således en oppgave for oppfinnelsen å skaffe til veie et svommefottoy som gjor det mulig for svbmmeren å anvende brystsvbmning med bket virkning samtidig som oppfinnelsen gjor det lettere å crawle og i tillegg hertil gjor det mulig for svbmmeren å gå med svbmmefottene montert. It is thus a task for the invention to provide a swimming foot toy which enables the swimmer to use breaststroke with a bent effect at the same time that the invention makes it easier to crawl and, in addition to this, makes it possible for the swimmer to walk with the swimming feet attached.
For dette formål er fottoyet ifblge oppfinnelsen kjenne-tegnet ved at svbmmefinnen danner en konkav skovleformet eller bseformet overflate med sin konkavitet rettet mot det indre parti av sålen og er forbundet med denne såle langs en buet linje som strekker seg fra midten av hælpartiet til den indre kant av tåen på nevnte såle med det sentrale parti av denne forbindelse sammenfal-lende med ytterkanten av sålens sentrale parti, idet den nedre kant av svbmmefinnen har en fordypning med trekantet form i sitt sentrale parti og på begge sider av fordypningen danner et par skrått oppad forlbpende rette kantpartier. For this purpose, the foot toy according to the invention is characterized by the fact that the swimming fin forms a concave shovel-shaped or basket-shaped surface with its concavity directed towards the inner part of the sole and is connected to this sole along a curved line that extends from the middle of the heel part to the inner edge of the toe of said sole with the central part of this connection coinciding with the outer edge of the central part of the sole, the lower edge of the sbmmme fin having a recess with a triangular shape in its central part and on both sides of the recess forming a pair slanting upwards continuous straight edge sections.
Oppfinnelsen skal beskrives nærmere i det fblgende i form av et eksempel og under henvisning til tegningen, hvor fig. 1 er et perspektivriss og fig. 2 et snitt i stbrre målestokk i et tverrgående plan gjennom fottøyets midtre parti. The invention shall be described in more detail below in the form of an example and with reference to the drawing, where fig. 1 is a perspective view and fig. 2 a section on a larger scale in a transverse plane through the middle part of the footwear.
Formen og sammensetningen av fottoyet ifblge oppfinnelsen fremgår uten videre av fig. 1 og 2. Fottoyet, som i det fblgende vil bli betegnet som svbmmeskoen, vil fortrinnsvis bli fremstilt av gummi ved hjelp av en egnet form som tillater stopning av svbmmefinnen 1 og svbmmeskoen 2 i ett eneste stykke. Skoen vil være mest mulig nbyaktig tilpasset fotens form og dimensjoner. Den kan for dette formål f.eks. ha en opphbyet forsterkning 3. The shape and composition of the foot toy according to the invention is readily apparent from fig. 1 and 2. The shoe, which in the following will be referred to as the swimming shoe, will preferably be made of rubber using a suitable mold which allows the padding of the swimming fin 1 and the swimming shoe 2 in one single piece. The shoe will be adapted as closely as possible to the shape and dimensions of the foot. For this purpose, it can e.g. have a suspended reinforcement 3.
Selve svbmmefinnen 1 strekker seg langs en buet flate, hvis konkave side er vendt mot fotens innerside. Den har en tykkelse som tiltar progressivt fra den nedre kant til den ovre kant og som ved denne ovre kant er forbundet med det nedre parti 4 som danner sålen av skoen. Den flate som beskrives av svbmmefinnen, er en flate med dobbelt bueform som ligner formen av en Peltonturbinskovle. Den buede forbindelseslinje mellom svbmmefinnen 1 og skoens såle 4 går ut fra hælens bakre ende i et punkt som befinner seg hovedsakelig i skoens midtre plan. Den strekker seg skrått i forhold til sålen, slik at den når ytterkanten av den sistnevnte i det sentrale parti, for deretter å bli avbdyet mot innerkanten idet den nærmer seg den forreste ende som har en åpning 5- Den forreste kant av svommefinnen strekker seg ut fra den forreste ende av skoen langs en bue som er rettet nedover, fremover og mot det indre av foten, mens den baker-ste kant strekker seg ut fra den bakre del av hælen langs en bue som er rettet nedover, bakover og innover i forhold til foten. På det sted hvor svommefinnen har sin storste lengde, er den således lenger enn skoen. Den nederste kant av svommefinnen har et hakk 6 som av-grenses av to trekantede elementer 7 og 8. The swimming fin 1 itself extends along a curved surface, the concave side of which faces the inner side of the foot. It has a thickness which increases progressively from the lower edge to the upper edge and which at this upper edge is connected to the lower part 4 which forms the sole of the shoe. The surface described by the svbmme fin is a surface with a double arc shape that resembles the shape of a Pelton turbine blade. The curved line of connection between the svbmme fin 1 and the sole 4 of the shoe starts from the rear end of the heel at a point located mainly in the middle plane of the shoe. It extends obliquely in relation to the sole, so that it reaches the outer edge of the latter in the central part, then is deflected towards the inner edge as it approaches the front end which has an opening 5- The front edge of the swimming fin extends from the front end of the shoe along an arc directed downwards, forwards and towards the inside of the foot, while the rear edge extends from the rear part of the heel along an arc directed downwards, backwards and inwards in relation to the foot. In the place where the swimming fin has its greatest length, it is thus longer than the shoe. The bottom edge of the swimming fin has a notch 6 which is bounded by two triangular elements 7 and 8.
Endelig vil det ved betraktning av fig. 2 bemerkes at den linje, langs hvilken svommefinnen er gjennomskåret i et plan på tvers av skoen, er en linje uten infleksjonspunkt, hvis bueradius er minst i nærheten av skoens såle og tiltar progressivt mot den nederste kant. Finally, when considering fig. 2, it is noted that the line along which the swimming fin is cut in a plane across the shoe is a line without an inflection point, the arc radius of which is least close to the sole of the shoe and increases progressively towards the bottom edge.
Det er kjent at når en svommer utforer normale benbevegelser under crawling vil fottenes bevegelse mot hverandre ved slutten av bevegelsen sdke å bevirke en reaksjonsdrivkraft ved for-skyvning av vannet bakover frembragt ved fottenes bevegelse mot hverandre. Takket være den buede form av svommefinnene 1 og hakket 6 er denne virkning betydelig forsterket når svbmmeren kan således holde seg ved vannoverflaten uten for stor anstrengelse selv når han bærer belastninger eller når han "hindres i sine bevegelser, f.eks. ved sin bekledning. It is known that when a swimmer performs normal leg movements during crawling, the movement of the feet towards each other at the end of the movement will help to cause a reaction driving force by displacing the water backwards produced by the movement of the feet towards each other. Thanks to the curved shape of the swimming fins 1 and the notch 6, this effect is significantly enhanced when the swimmer can thus stay at the surface of the water without too much effort even when he is carrying loads or when he is "impeded in his movements, for example by his clothing.
Man har forovrig funnet at takket være sin spesielle form kan svommefinnen 1 boye seg mot seg selv når den utsettes for en kraft rettet mot skosålen, slik at det er mulig for svommeren å gå på selve marken når han er utstyrt med den beskrevne svommesko idet svommefinnen da boyer seg under skoen. Da skoen ér fremstilt i ett stykke av gummi, vil svommefinnen ikke ha noen tendens til å bli deformert eller sprekke og bibeholder sin form vist på figuren når den er fri. It has also been found that, thanks to its special shape, the swimming fin 1 can bend towards itself when it is subjected to a force directed against the sole of the shoe, so that it is possible for the swimmer to walk on the field itself when he is equipped with the described swimming shoe as the swimming fin then bends under the shoe. As the shoe is made in one piece of rubber, the swimming fin will have no tendency to deform or crack and will retain its shape shown in the figure when it is free.
Som nevnt ovenfor, anvender man for selve skokroppen og for svommefinnen et mykt materiale som har en viss naturlig elasti-sitet, såsom naturgummi eller syntetisk gummi. Imidlertid, kan like^As mentioned above, a soft material that has a certain natural elasticity, such as natural rubber or synthetic rubber, is used for the shoe body itself and for the swimming fin. However, may like^
ledes andre syntetiske materialer tenkes. other synthetic materials are considered.
Svommefinnen kan boye seg under sålen på skoen når The fin can bend under the sole of the shoe when
svommeren går på marken. For det formål å lette denne boyning kan man anordne festeorganer som fikserer svommefinnen i en sammenbrettet stilling under sålen. Man kan også anordne en stropp som er festet ved den ene ende til den ovre kant av skoen, som normalt er rullet opp omkring en pinne eller plugg og som kan strekkes ut under svbmme-finnen, idet den frie ende festes til toppen av nevnte pinne. Andre festeorganer kan likeledes være anordnet. Endelig kan svbmmefinnen i en annen utfbrelsesform og for å være forbundet med skoen langs en linje som strekker seg i sålens lengderetning, være forbundet med skoens overdel eller sålens ytterkant. the swimmer walks on the field. For the purpose of facilitating this boyning, fastening means can be arranged which fix the swimming fin in a folded position under the sole. One can also arrange a strap which is attached at one end to the upper edge of the shoe, which is normally rolled up around a stick or plug and which can be stretched out under the svbmme fin, the free end being attached to the top of said stick . Other fastening means can also be arranged. Finally, in another embodiment and in order to be connected to the shoe along a line extending in the longitudinal direction of the sole, the swimming fin can be connected to the upper part of the shoe or the outer edge of the sole.
