Description

Patentbeskrivelse Patent description

Lydabsorberende paneler laget av stivt gitter og lyddempende brikker festet i maskene. Sound-absorbing panels made of rigid mesh and sound-absorbing pieces fixed in the mesh.

Oppfinnelsen angår akustiske paneler som brukes for å dempe støy og klang i private og offentlige rom. The invention relates to acoustic panels that are used to dampen noise and reverberation in private and public spaces.

I dagens marked for lyddempende produkter finnes et stort utvalg av akustiske paneler. Ser man bort fra lyddempende tepper og kunstneriske installasjoner er i all hovedsak de industrielt fremstilte lyddempende produktene laget som matter eller polstrede paneler. In today's market for soundproofing products, there is a large selection of acoustic panels. Disregarding sound-absorbing carpets and artistic installations, the industrially produced sound-absorbing products are mainly made as mats or padded panels.

Panelene er gjerne helt eller delvis støpt i et lydabsorberende materiale eller et overflatemateriale er trukket/kledt rundt en lydabsorberende kjerne. Akustiske paneler, skjermvegger, skillevegger, og stillerom er bygget opp på denne måten i dagens marked. Produktene har en relativt stor flate som absorberer lyden. De er laget som stive paneler som kan festes til vegg, til himling, til bordplate, på fot etc. The panels are often completely or partially cast in a sound-absorbing material or a surface material is drawn/clad around a sound-absorbing core. Acoustic panels, screen walls, partitions and quiet rooms are built in this way in today's market. The products have a relatively large surface that absorbs the sound. They are made as rigid panels that can be fixed to the wall, to the ceiling, to the table top, on a foot etc.

I de senere år har det også kommet produkter på markedet som tar i bruk mindre paneler/fliser som fungerer som brikker i et system som danner større lydabsorberende flater når disse festes sammen. Felles for disse systemene er at brikkene festes til- eller i hverandre og danner tette eller transparente brynje-lignende vegger eller romdelende strukturer som må henge, fra himling eller fra- eller mot vegg. In recent years, products have also appeared on the market that use smaller panels/tiles that act as pieces in a system that form larger sound-absorbing surfaces when these are attached together. What these systems have in common is that the pieces are attached to or in each other and form dense or transparent breastplate-like walls or room-dividing structures that must hang, from the ceiling or from or against the wall.

Innen et helt annet marked finnes en rekke gitterprodukter i metall, i form av gjerder, gangrister, sikringsvern, armering etc. Disse produktene er i all hovedsak tilpasset for utvendig bruk eller til røffe miljøer som bygg og anlegg, industriarbeidsplasser, lager etc. Within a completely different market there are a number of metal grating products, in the form of fences, walkways, safety guards, reinforcement etc. These products are mainly adapted for external use or for rough environments such as construction, industrial workplaces, warehouses etc.

Øvrig kjent teknikk fremgår av patent nr. CN 102852262 A og US 4130682 A. Other known technology appears in patent no. CN 102852262 A and US 4130682 A.

Oppfinnelsen er inspirert av elementer fra disse to ulike produktsegmentene. Ved å utforme komponenter fra disse ulike produktområdene til å passe sammen kan de kombineres til en nyvinning markedet ikke har sett. The invention is inspired by elements from these two different product segments. By designing components from these different product areas to fit together, they can be combined into an innovation the market has not seen.

Omfanget av oppfinnelsen fremgår av de etterfølgende patentkrav. The scope of the invention appears from the subsequent patent claims.

Ved bruk av en stiv gitterkonstruksjon som kjerne og bæring til et lydabsorberende panel kan man feste brikker av et lyddempende materiale, f.eks. filt, til gitterets masker. Ved å fylle maske-radene med lyddempende brikker oppnås det dannelse av et slags piksel-inndelt panel med én- eller tosidig lyddempende overflate. Tilsvarende pikselbruk i en TV / dataskjerm vil panelet kunne lages med billedlig og mønstret overflate. When using a rigid grid construction as the core and support for a sound-absorbing panel, you can attach pieces of a sound-absorbing material, e.g. felt, for the stitches of the lattice. By filling the mesh rows with sound-absorbing pieces, the formation of a kind of pixel-divided panel with a one- or two-sided sound-absorbing surface is achieved. Corresponding to the use of pixels in a TV / computer screen, the panel can be made with a pictorial and patterned surface.

De fylte maskene i gitteret kan minne om sterkt forstørrede masker i et teppe. Et teppe er mykt og ikke selvbærende, men må henges opp eller bli lagt mot en flate. Oppfinnelsen av det nye lydabsorberende panelet er stivt og selvbærende, med de konstruksjonsmulighetene og fordelene som følger med dette. The filled stitches in the lattice can resemble greatly enlarged stitches in a carpet. A carpet is soft and not self-supporting, but must be hung up or laid against a surface. The invention of the new sound-absorbing panel is rigid and self-supporting, with the construction possibilities and advantages that come with this.

Paneler montert sammen i rapport (del av et mønster som gjentas regelmessig) vil kunne danne større flater. Panelenes form og / eller omriss kan variere fra flate rektangulære- til 3-dimmensjonale irregulære utforminger. Med mulighet til å lage gitterkjerner som plane-, krumme- og dobbeltkrumme rammeverk som kan monteres sammen, vil man -ved å fylle maskene med lydabsorberende brikker- kunne oppnå å danne lyddempende produkter i alt fra små og store flate skjermer, til selvbærende 3-dimensjonale konstruksjoner, eksempelvis utformet som en kube, pyramide, DNA-heliks eller iglo. Panels fitted together in rapport (part of a pattern that repeats regularly) will be able to form larger surfaces. The shape and / or outline of the panels can vary from flat rectangular to 3-dimensional irregular designs. With the possibility to create grid cores as planar, curved and double curved frameworks that can be assembled together, one will -by filling the meshes with sound-absorbing pieces- be able to create sound-absorbing products in everything from small and large flat screens, to self-supporting 3- dimensional constructions, for example designed as a cube, pyramid, DNA helix or igloo.

Det ligger et stort potensiale i fleksibiliteten som oppfinnelsen kan tilby markedet. I tillegg til en standardisert utformet produktserie muliggjør den nye teknikken å lage helt skreddersydde løsninger for individuelle ønsker uten for høye kostnader. Det er et enormt behov for lyddempende flater i nyere arkitektur der romløsningene ofte består av store lineære harde flater som gir altfor mye gjenklang. Med utformingsmulighetene som ligger i oppfinnelsen, vil man i mye større grad enn med dagens produkter kunne møte arkitektenes ønske/krav om lyddempende produkter som en integrert del av det arkitektoniske uttrykket. There is great potential in the flexibility that the invention can offer the market. In addition to a standardized designed product range, the new technique makes it possible to create completely tailored solutions for individual wishes without excessive costs. There is an enormous need for sound-absorbing surfaces in recent architecture where the room solutions often consist of large linear hard surfaces that give way too much reverberation. With the design possibilities inherent in the invention, one will be able to meet the architects' wishes/demands for sound-absorbing products as an integral part of the architectural expression to a much greater extent than with current products.

Den bærende kjernen i panelet -gitteret- kan produseres på ulike måter. Den mest hensiktsmessige produksjonsformen for masseproduksjon vil sannsynligvis være sveiset trådgitter, tilsvarende et stivt gittergjerde. Gitteret kan med fordel produseres i flere standarder med ulike maskestørrelser for å gi de ferdig panelene et spekter av størrelser og uttrykk. Gitteret i panelene kan eksempelvis produseres uten ramme for veggoppheng, og med ramme for å gi bedre avstiving og mulighet for sammenkobling av paneler. Andre produksjonsformer for gitteret vil kunne være strekkmetall, stansing, støp, vann- eller laserskjæring av plast, metall eller andre egnede materialer. The supporting core of the panel - the grid - can be produced in various ways. The most suitable form of production for mass production will probably be welded wire mesh, corresponding to a rigid mesh fence. The grid can advantageously be produced in several standards with different mesh sizes to give the finished panels a range of sizes and expressions. The grid in the panels can, for example, be produced without a frame for wall hanging, and with a frame to provide better bracing and the possibility of connecting panels. Other forms of production for the grid could be expanded metal, punching, casting, water or laser cutting of plastic, metal or other suitable materials.

Produksjon av brikker som skal fylle maskene i gitteret, eller festes til dem, er i hovedsak tenkt stanset eller kappet i lydabsorberende filt, men andre materialer og produksjonsformer kan også vise seg å være aktuelle. Filt gir god lyddemping, men har en relativt høy kostnad. Eksempler på andre hensiktsmessige materialer til bruk kan være rester fra tekstilindustrien, dekorsøm på brikkene, lys eller innslag av farger, mønster i ulike materialer, for å gi en ønsket effekt i forhold til produktenes overflate og uttrykk. Production of pieces that will fill the meshes in the grid, or be attached to them, is mainly thought to be punched or covered in sound-absorbing felt, but other materials and forms of production may also prove to be relevant. Felt provides good sound dampening, but has a relatively high cost. Examples of other suitable materials for use can be remnants from the textile industry, decorative stitching on the pieces, light or touches of colour, patterns in various materials, to give a desired effect in relation to the product's surface and expression.

De lydabsorberende brikkene kan utformes på ulike måter for å festes til det bærende gitteret. Figurene 1-3 viser to ulike måter å feste brikkene til gitteret. The sound-absorbing pieces can be designed in various ways to be attached to the load-bearing grid. Figures 1-3 show two different ways of attaching the pieces to the grid.

Figur 1 og 2 viser et standard metallgitter 2 hvor brikker i filt 1 er presset gjennom gitterets masker 3 som piksler som danner en større bildeflate. Figures 1 and 2 show a standard metal grid 2 where pieces of felt 1 are pressed through the grid's meshes 3 as pixels that form a larger image surface.

Figur 1 viser til venstre filtbrikken 1 ferdig utskåret og til høyre filtbrikken 1 presset gjennom, og festet til en av maskene 3 i gitteret 2. Filtbrikken 1 er utformet med spor som fungerer som brikkens låseanordning 4 for å feste brikken 1 i riktig posisjon til maskene 3 til gitteret 2. Figure 1 shows on the left the felt piece 1 completely cut out and on the right the felt piece 1 pressed through, and attached to one of the meshes 3 in the grid 2. The felt piece 1 is designed with a groove that functions as the piece's locking device 4 to attach the piece 1 in the correct position to the meshes 3 to the grid 2.

Figur 2 viser fire måter å feste filtbrikker 1 til maskene 3 i et standard metallgitter 2, som gir forskjellig struktur og uttrykk i flatene som dannes når de ulike filtbrikkene 1 festes til maskene 3. Figure 2 shows four ways of attaching felt pieces 1 to the meshes 3 in a standard metal grid 2, which gives different structure and expression in the surfaces that are formed when the various felt pieces 1 are attached to the meshes 3.

Figur 3 viser større brikker 1 som er skåret ut fra matter av filt. De er festet til et standard gitter 2 med to låseanordninger 4 som er tredd gjennom gitterets masker 3. Låseanordningene 4 er utrustet med mothaker 5 og et snitt 6 er skåret i front, for at låseanordningene 4 enkelt kan bøyes bakover så brikken 1 henger pent ned på forsiden. For å feste disse brikkene 1 benytter man på langt nær alle maskene 3 i gitteret 2. Dette betyr at det kan være hensiktsmessig å utvikle forskjellige formasjoner av gitter 2 til ulike brikker 1 avhengig av hva slags struktur og uttrykk man ønsker å få frem i den ferdige overflaten som dannes når flere brikker 1 festes til gitteret 2. Figure 3 shows larger pieces 1 which have been cut out from felt mats. They are attached to a standard grid 2 with two locking devices 4 which are threaded through the grid's meshes 3. The locking devices 4 are equipped with barbs 5 and a cut 6 is cut in the front, so that the locking devices 4 can easily be bent backwards so that the piece 1 hangs down neatly on the front page. To attach these pieces 1, one uses almost all the meshes 3 in the grid 2. This means that it may be appropriate to develop different formations of grid 2 for different pieces 1, depending on what kind of structure and expression one wants to achieve in it finish the surface that is formed when several pieces 1 are attached to the grid 2.

Begge løsningene i figurene 1-3 benytter et stivt gitter 2 som bærende struktur, hvor flere brikker 1 festes til gitterets masker 3, som sammen danner et selvbærende lydabsorberende panel. Both solutions in Figures 1-3 use a rigid grid 2 as a supporting structure, where several pieces 1 are attached to the meshes 3 of the grid, which together form a self-supporting sound-absorbing panel.
