Description
Elastisk bånd. Elastic band.
Oppfinnelsen vedrører elastiske bånd av den type som er særlig egnet for bruk i møbelindustrien som underlag for puter i stoler m. v. The invention relates to elastic bands of the type that are particularly suitable for use in the furniture industry as a base for cushions in chairs etc.
Det kjennes fra tidligere elastiske snorer i form av lange skruefjærer innlagt i f. eks. et plastovertrekk. Slike elastiske snorer er imidlertid dårlig egnet til det ovenfor nevnte formål i møbelindustrien, da de gir en liten flate for hensiktsmessig understøttelse slik at stolputene blir skjemmet eller beskadiget av understøttelsen. It is known from earlier elastic cords in the form of long coil springs embedded in e.g. a plastic cover. However, such elastic cords are poorly suited for the above-mentioned purpose in the furniture industry, as they provide a small surface for appropriate support so that the chair cushions are disfigured or damaged by the support.
Det kjennes fra tidligere forskjellige typer av elastiske bånd, i hvilke er innstøpt en armering av fjærviklet eller -bøyet tråd. It is known from earlier different types of elastic bands, in which a reinforcement of spring-wound or -bent wire is embedded.
Oppfinnelsen tar sikte på å tilveie-bringe elastiske bånd av en type som er særdeles enkel og praktisk, samt forholds-vis billig i fremstilling, samtidig som det fåes letthåndterlige, smidige bånd med stor styrke og god f jæring. The invention aims to provide elastic bands of a type which is particularly simple and practical, as well as relatively cheap to manufacture, while at the same time providing easy-to-handle, flexible bands with great strength and good suspension.
Ifølge oppfinnelsen oppnås dette ved According to the invention, this is achieved by
at der fremstilles bånd som kjennetegnes ved at de er utformet som et relativt tynt, flatt bånd av ettergivende og/eller elastisk materiale, hvilket bånd er forsynt med iallfall to langsgående vulstpartier, som rager ut fra båndets ene side, fortrinnsvis en vulst langs hver av båndets sidekanter, idet der inne i hver vulst er anordnet en fortløpende tettviklet skruefjær og den bort fra nevnte vulster vendende side av båndet er stort sett plan. that bands are produced which are characterized by the fact that they are designed as a relatively thin, flat band of yielding and/or elastic material, which band is provided with at least two longitudinal bead sections, which protrude from one side of the band, preferably one bead along each of the band's side edges, since inside each bead there is arranged a continuously tightly wound coil spring and the side of the band facing away from said beads is largely flat.
Elastiske bånd fremstillet i overens-stemmelse med oppfinnelsen gir enkle og solide midler som med stor fordel kan an-vendes i møbelindustrien bl. a. for under-støttelse av puter i stoler m. v. Båndene kan med fordel fremstilles av et billig rå-materiale som plast, og de i de langsgående vulster innlagte fjærer kan likeledes være av vanlig kjent skruefjærtype. Ved å tilpasse antall innlagte skruefjærer etter den belastning båndet ventes utsatt for får man et meget solid elastisk bånd som ikke er tilbøyelig til varig deformasjon selv ved lang tids bruk. Ved at kantvulstene anordnes på den ene side av båndet slik at dettes annen side blir plan, fåes en gunstig understøttelse, f. eks. av stolputer slik at disse ikke er skjemmet eller beskadiget ved striper innpresset i puten slik ellers vanlig er tilfelle. Båndets lengdekan-ter gjøres da fortrinnsvis jevnt avrundet i overgangen til kantvulstene. Elastic bands produced in accordance with the invention provide simple and solid means which can be used with great advantage in the furniture industry, among others. a. for supporting cushions in chairs, etc. The bands can advantageously be made from a cheap raw material such as plastic, and the springs embedded in the longitudinal beads can likewise be of the commonly known coil spring type. By adjusting the number of inserted coil springs according to the load the band is expected to be exposed to, you get a very solid elastic band that is not prone to permanent deformation even with long-term use. By arranging the edge beads on one side of the band so that the other side is flat, a favorable support is obtained, e.g. of chair cushions so that these are not disfigured or damaged by stripes pressed into the cushion, as is otherwise usually the case. The strip's longitudinal edges are then preferably evenly rounded in the transition to the edge beads.

Båndet ifølge fig. 1 er utformet som et flatt bånd 1, f. eks. av plastmateriale, utformet med en langsgående kantvulst 2 langs hver sidekant. Inne i disse kantvul-ster er der så anordnet skruefjærer 3. Båndet kan enten være fremstillet ved hensiktsmessig ekstrudering og fjær elementene er anbragt etterpå, eller båndet kan være fremstillet samtidig med innleggelse eller innstøpning av fjærelementene. The tape according to fig. 1 is designed as a flat band 1, e.g. of plastic material, designed with a longitudinal edge bead 2 along each side edge. Screw springs 3 are then arranged inside these edge beads. The band can either be produced by appropriate extrusion and the spring elements are placed afterwards, or the band can be produced at the same time as inserting or embedding the spring elements.
Fig. 2 viser en noe modifisert utførelse hvor båndet 1' er forsynt med tre langsgående vulster, i hver av hvilke er innlagt et fjærelement 3'. Fig. 2 shows a somewhat modified version where the band 1' is provided with three longitudinal beads, in each of which a spring element 3' is inserted.
Det vil umiddelbart forståes at oppfinnelsen ikke er begrenset til det ovenfor viste og beskrevne, idet antall vulster og innlagte fjærelementer selvsagt kan varie-res over et vidt område alt etter den It will immediately be understood that the invention is not limited to what is shown and described above, as the number of beads and embedded spring elements can of course be varied over a wide range depending on the
