Description
Anordning ved gummistøvler med forlengelsesskaft. Device for rubber boots with extension shaft.
Oppfinnelsen omhandler en gummi-støvel som har et avtagbart forlengelsesskaft i den hensikt å fremskaffe en prak-tisk gummistøvel til sportsbruk som kan brukes til vadestøvel når forlengelsesskaftet er påsatt, idet dette hurtig kan fjernes når det ikke trenges. The invention relates to a rubber boot which has a removable extension shaft with the aim of providing a practical rubber boot for sports use which can be used as a wading boot when the extension shaft is attached, as this can be quickly removed when not needed.
Det er foreslått flere utførelser av slike Several designs of such have been proposed
støvlkombinasjoner, som har det fellestrekk at støvlskaftets topp er forsynt med en avstivningsring. Denne stive ring er gjerne permament festet og den gjør bruken av støvlen ubehagelig når skaftet er fjernet. boot combinations, which have the common feature that the top of the boot shaft is provided with a stiffening ring. This rigid ring is usually permanently attached and it makes the use of the boot uncomfortable when the shaft is removed.
I motsetning til disse kjente utførelser er avstivningsringen, som er nødvendig hvis forbindelsen mellom skaftene skal bli tett, anbrakt i forlengelsesskaftets nedre del i en utvendig vulst på denne, og støvl-skaftets toppdel trekkes utenpå forlengelsesskaftets nedre del og over vulsten. For å oppnå en absolutt tetthet er det i en inn-overvendende gummivulst i støvlskaftets toppkant innlagt en elastisk snor som til-later at skafttoppen kan gli over forlengelsesskaftets utvendige vulst og som trekker skafttoppen sammen igjen, slik at den tet-ter rundt vulsten på forlengelsesskaftet. For at denne tetning ikke skal påvirkes av strekk i vertikalretningen under gangen er det i forlengelsesskaftets nedre dels innerflate anbragt et antall trykknapper som passer inn i tilsvarende festedeler i støvlskaftet, når de to skaft er i tetnings-stilling med hverandre. In contrast to these known designs, the stiffening ring, which is necessary if the connection between the shafts is to be tight, is placed in the lower part of the extension shaft in an external bead on this, and the top part of the boot shaft is pulled outside the lower part of the extension shaft and over the bead. In order to achieve absolute tightness, an elastic cord is inserted into an inward-facing rubber bead at the top edge of the boot shaft, which allows the shaft top to slide over the outer bead of the extension shaft and which pulls the shaft top together again, so that it seals around the bead on the extension shaft . In order for this seal not to be affected by tension in the vertical direction during the walk, a number of push buttons are placed in the inner surface of the lower part of the extension shaft, which fit into corresponding fastening parts in the boot shaft, when the two shafts are in a sealing position with each other.
Oppfinnelsen vil bli nærmere forklart i forbindelse med tegningen, hvor: Fig. 1 viser et lengdesnitt gjennom de to skaft i atskilt stilling. Fig. 2 viser de to skaft forbundet med hverandre. Fig. 3 viser den komplette støvl med The invention will be explained in more detail in connection with the drawing, where: Fig. 1 shows a longitudinal section through the two shafts in a separate position. Fig. 2 shows the two shafts connected to each other. Fig. 3 shows the complete boot with
påsatt forlengelsesskaft for bruk som vade-støvl. attached extension shaft for use as wading boot.
Gummistøvlens skaft 1 hvis toppkant på vanlig måte er forsynt med en gummi-bord 2 har i overkanten en gummivulst med en innlagt snor 3. Denne kan bestå av en ringformet skrufjær, eller det kan være en snor av annet noe elastisk materiale som f. eks. Nylon. I skaftets øvre dels inn-side er enten utformet festedeler for trykk-knappene 9, eller det er festet festedeler av metall eller annet egnet materiale. The rubber boot's shaft 1, the top edge of which is normally provided with a rubber table 2, has a rubber bead at the top edge with an inserted cord 3. This can consist of a ring-shaped coil spring, or it can be a cord of some other elastic material such as . Nylon. In the inside of the upper part of the shaft, either fastening parts for the push buttons 9 are designed, or fastening parts made of metal or other suitable material are attached.
I forlengelsesskaftets 5 nedre del er utformet en utvendig vulst 6 som går over i en skarp kant langs skaftets nedre kant. In the lower part of the extension shaft 5, an external bead 6 is formed which merges into a sharp edge along the lower edge of the shaft.
I denne vulst er innlagt en avstivningsring 8. I skaftets 5 nedre del er festet et antall A stiffening ring 8 is inserted into this bead. In the lower part of the shaft 5, a number of
trykknapper 9 som korresponderer med tilsvarende festedeler 4 i støvleskaftet, når skaftene er bragt i samvirkende tetnings-stilling med hverandre, som vist på fig. 2. push buttons 9 which correspond to corresponding attachment parts 4 in the boot shaft, when the shafts are brought into a cooperating sealing position with each other, as shown in fig. 2.
Disse trykknapper, som holder de to skaft These snaps, which hold the two shafts
sammen og motvirker gjensidige beveg-elser mellom disse i lengderetningen, og da især under gangen, er av den største betyd-ning for opprettholdelsen av en tett forbindelse mellom skaftene. Trykknappene kan også erstattes av andre organer, som f. eks. spenner eller hekter. Andre utfør-elsesformer kan også anvendes innenfor rammen av de oppstillete påstander. Såle-des kan snoren eller ringen 3 være uelastisk og ha en diameter som er tilnærmet den samme som for ringen 8. Når støvlen og forlengelsesskaftet skal sammensettes blir den nedre ende av det sistnevnte med ringen 8 ført i skråstilling ned gjennom støvleskaftets toppåpning som da utvides ovalt inntil vulsten med ringen 8 har pas-sert gjennom vulsten med snoren 3. Når forlengelsesskaftes så trekkes oppover vil together and counteracts mutual movements between these in the longitudinal direction, and especially during the passage, is of the greatest importance for maintaining a tight connection between the shafts. The push buttons can also be replaced by other bodies, such as e.g. buckles or hooks. Other embodiments can also be used within the framework of the stated claims. Thus, the string or ring 3 can be inelastic and have a diameter that is approximately the same as that of the ring 8. When the boot and the extension shaft are to be assembled, the lower end of the latter with the ring 8 is led in an oblique position down through the top opening of the boot shaft, which then expands oval until the bead with the ring 8 has passed through the bead with the string 3. When the extension shaft is pulled upwards,
