Abstract

1. A method of making mattresses, chair seats or the like upholstery elements from two blocks (1) of foamed plastics between which spring elements (4) are provided, the ends of said spring elements being secured by a casting operation to at least one of said blocks of foamed plastics, characterized in that a layer (5) of a liquid, curable and self-extinguishing polyurethane is applied onto the inner support surface of the block (1) of foamed plastics intended to which the ends of said spring elements (4) are to be secured, that the ends of the spring elements (4) are inserted into the still liquid polyurethane layer (5), and that thereupon the polyurethane layer is cured while the formation of foam is suppressed.

Description

i Den foreliggende oppfinnelse vedrører en fremgangsmåte ved fremstilling av.madrasser, stolseter e.l. av skumstoffmateriale, f.eks. blokkstøpt polyuretan, med to motsatt rettede ytre anleggsflater, og med to motstående indre anleggsflater og fjærinnlegg i rommet mellom disse. i The present invention relates to a method for the production of mattresses, chair seats, etc. of foam material, e.g. block-cast polyurethane, with two oppositely directed outer contact surfaces, and with two opposite inner contact surfaces and spring inserts in the space between them.

Ifølge de kjente metodermonteres fjærene mellom en stålramme som trekkes med stoff og hvor det som stopning i madrassens ligge-flate benyttes ulike.typer materiale, også skumgummi og skumplast. According to the known methods, the springs are mounted between a steel frame that is covered with fabric and where various types of material, including foam rubber and foam plastic, are used as stuffing in the mattress's lying surface.

Fra svensk patent 388 346 og US-Reissue patent 24 914 er kjent From Swedish patent 388 346 and US-Reissue patent 24 914 is known

en madrass hvor fjærendene under skummingsprosessen av det materiale som avgrenses av nevnte ytre og indre anleggsflater, inn-leires- i skumstoffmaterialet. Dette er imidlertid en komplisert og kostbar løsning. I nevnte US-patent er herdetiden 30 minutter. Den forliggende oppfinnelse tilsikter således å tilveiebringe en fremgangsmåte hvorved unngås en skummingsprosess i forbindelse med festingen av fjærene, samtidig som utherdingen skjer raskt og produksjonstiden således reduseres. a mattress where the spring ends during the foaming process of the material delimited by said outer and inner contact surfaces are embedded in the foam material. However, this is a complicated and expensive solution. In the aforementioned US patent, the curing time is 30 minutes. The present invention thus aims to provide a method by which a foaming process is avoided in connection with the fastening of the springs, at the same time that curing takes place quickly and the production time is thus reduced.

Ifølge oppfinnelsen blir minst en av de to indre anleggsf låtene påført flytende, herdbar og selvslukkende polyuretan som etter utherdingen danner et bærende sjikt og forankrer fjærenes anleggsflater med skumstoffmaterialet. According to the invention, liquid, hardenable and self-extinguishing polyurethane is applied to at least one of the two inner contact layers which, after curing, forms a load-bearing layer and anchors the contact surfaces of the springs with the foam material.

I utgangspunktet benyttes blokkstøpt polyuretanskum til utvendig stopning. På dette skummet påføres et lag med selvslukkende polyuretan (kaldtherdende), hvorpå fjærinnlegget legges an mot dette belegget. Det selvslukkende polyuretanet har i denne sammenheng mangesidige oppgaver: a) Det binder fjær og skum sammen til en sterk og homogen sammen-føyning. b) Den danner et bæresjikt mellom stålfjær og skum, ved at det selvslukkende polyuretanet trenger ned i porene i det blokk-støpte skummet som anvendes til støpning, og danner således et "slitebelegg" mellom fjær og skum, som motvirker at stål-fjærene arbeider seg ned i skummet, og derved forårsaker skadar. Basically, block-moulded polyurethane foam is used for external padding. A layer of self-extinguishing polyurethane (cold-hardening) is applied to this foam, after which the spring insert is placed against this coating. In this context, the self-extinguishing polyurethane has multifaceted tasks: a) It binds feathers and foam together into a strong and homogeneous joint. b) It forms a support layer between the steel spring and foam, by the self-extinguishing polyurethane penetrating into the pores of the block-cast foam used for casting, and thus forms a "wear coating" between the spring and foam, which prevents the steel springs from working sinks into the foam, thereby causing damage.

c) I tillegg låser det selvslukkende polyuretanet fjærene fast c) In addition, the self-extinguishing polyurethane locks the springs firmly

c) i et stabilt leie, som gjør at fjærene ikke påvirkes av uhel- dige belastninger, som derved igjen kan resultere i fjær-brudd etter forholdsvis kort tid. Polyuretanet har slike egen- skaper at en særskilt høy rivestyrke oppnås. c) in a stable bearing, which means that the springs are not affected by accidents heavy loads, which can thereby again result in spring breakage after a relatively short time. The polyurethane has such properties means that a particularly high tear strength is achieved.

Ved denne prosess blir fjærenes anlegg mot blokken støpt fast i denne. Etter utherding (vanligvis ca. 4. minutter) vil disse sitte fast i sjiktet og med den fleksibilitet som polyuretanen har vil gjøre at sammenføyningen får stor styrke og vil gi en In this process, the contact of the springs against the block is cast firmly into it. After curing (usually approx. 4 minutes) these will be stuck in the layer and with the flexibility that the polyurethane has will make the joint gain great strength and will give a

-homogen overflate. - homogeneous surface.

Oppfinnelsen vil i det etterfølgende bli nærmere forklart i forbindelse med vedlagte tegning som skjematisk fremstiller oppfinnelsen. Figuren viser således en del av madrassen i snitt sett fra siden med blokkstøpt polyuretan 1 hvor det mellom de indre anleggsflater er rom 2 for fjærene som skal faststøpes. The invention will subsequently be explained in more detail in connection with the attached drawing which schematically presents the invention. The figure thus shows a part of the mattress in section seen from the side with block-moulded polyurethane 1, where there is room 2 between the inner contact surfaces for the springs to be cast in place.

I figuren betegner 1 den blokkstøpte polyuretan hvor det er dannet et rom 2 midtveis mellom de ytre liggeflater 3.4 betegner fjærene som ved sine anleggsflater mot blokkene 1 støpes fast til disse med et selvslukkende lag 5 av polyuretan som samtidig danner det bærende sjikt mot fjærenes anleggsflater. In the figure, 1 denotes the block-cast polyurethane where a space 2 is formed midway between the outer lying surfaces 3.4 denotes the springs which, at their contact surfaces against the blocks 1, are cast firmly to these with a self-extinguishing layer 5 of polyurethane which at the same time forms the bearing layer against the contact surfaces of the springs.
