Laitelma suojakerroksella varustetussa elastisessa kappaleessa - Anordning vid elastisk kropp med skyddsskikt Tämä keksintö koskee elastista kappaletta, jonka ulkopinta on kokonaan tai osittain varustettu suojakerroksella.
5 Kappale on yleensä valmistettu muovista, joka sitä ennen on saanut vaahdota tai paisua. Kappale tulee tällöin koostumaan useista kennoista, joista kukin sulkee sisäänsä tietyn tilavuuden. Nämä kennot on rei'itetty niin, että ilma voi virrata niiden läpi. Kennojen rei'ittäminen saadaan aikaan 10 käsittelemällä valmistettua kappaletta lämmöllä. Tällainen kappale varustettaan kokonaan tai osittain filmillä, joka on joko kääritty kappaleen ympäri tai on muulla tavalla kiinnitetty kappaleeseen. Kiinnitettäessä voidaan käyttää liima-aineita tai muita tunnettuja menetelmiä. Eräs menetelmä on 15 tehdä kappaleen ulkopinta takertuvaksi lämmittämällä, jolloin pinnalle sijoitettu filmi kiinnittyy siihen. Filmin tarkoituksena on estää kosteuden tunkeutuminen kappaleeseen ja lisäksi on filmin oltava sellainen, että aineet, bakteerit ja muut hiukkaset, jotka voivat helposti kiinnittyä suo-20 jakerrokseen, voidaan poistaa, esimerkiksi sopivien puhdistusaineiden avulla. Tietyissä tapauksissa voi myös autoklaa-vikäsittely olla sopiva. Edelläesitetyn tyyppiselle, suoja-kerroksella päällystetylle kappaleelle on useita sovellutuskohteita. Eräs sovellutuskohde on sängyn patja ja tällöin 25 kappale on yleensä suunnikassärmiön muotoinen. Patjan ylä-ja alapinta sekä sen pitkittäiset sivupinnat on päällystetty edellä mainitulla suojakerroksella. Poikittaisia sivupintoja sitävastoin ei ole päällystetty, jotta ilmaa voisi virrata patjan kennoihin. Tämäntyyppisen suunnikassärmiön muotoisen 30 kappaleen päällystetyt pinnat ovat yleensä hieman karheat, jotta päällystekerros ei olisi tasainen. Tämä mahdollistaa ilmankierron kerroksen yläpinnan ja patjan käyttäjän välillä. Tällaista patjaa käytettäessä aiheuttaa käyttäjän liikehdintä patjalla narisevan äänen, joka on häiritsevä jollei käyt-35 täjä ole yksin huoneessa.
2 71475 Tämän keksinnön tarkoituksena on poistaa edellä esitetyt häiritsevät äänet. Tämä saadaan aikaan siten/ että kappaleen ja mainitun suojakerroksen väliin sijoitetaan kudos, joka voi olla kiinnitettynä sekä suojakerrokseen että itse 5 kappaleeseen.
Sopiva aine kudosta varten on charmeuse-nailon. Tämän paino voi olla 63 g/m .
Sopiva aine itse patjakappaletta varten on polyeette-ri. Polyeetteriä käytettäessä on sen painon oltava 30 kg/ 3 10 m . Lisäksi voidaan käyttää erittäin elastista kylmävaahtoa, joka on kylmävaahdotettua polyeetteriä. Tämän painon on ol- 3 tava 37 kg/m .
Tämän keksinnön muut tunnusmerkit ilmenevät seuraavasta patenttivaatimuksesta.
15 Tämä keksintö selitetään lähemmin viitaten oheiseen piirustukseen, jossa kuviot esittävät perspektiivisesti patjaa sen eri valmistusvaiheissa.
Kuviossa 1 tarkoittaa patjaa, joka muodostuu suuntais-särmiön muotoisesta ytimestä, joka on muovia, joka valmis-20 tuksen aikana on saanut laajentua ja muodostaa vaahto, joka käsittää useita kennoja, jotka kaikki ympäröivät omaa tilaansa. Kennot on valmistuksen aikana rei'itetty lämpökäsittelyn avulla niin, että ilma voi kiertää kennojen läpi. Sopiva aine ydintä varten on edelläesitetyn mukainen aine, joka 25 on selotettu liitteessä I. Patjaytimessä on yläosa 2, alaosa 3, kaksi pitkittäissivua 6 ja 7 ja kaksi päätysivua 4 ja 5. Yläosan 2, alaosan 3 ja pitkittäissivujen 6 ja 7 yli on levitetty kaksi kudospuolikasta niin, että nämä pinnat peittyvät kokonaan. Pitkittäissivujen 6 ja 7 kohdalla kudospuo-30 likkaitten vastakkaiset reunat kohtaavat toisensa. Kudos on sopivimmin charmeuse-naiIonia, mutta on tietysti mahdollista käyttää muita kudostyyppejä. Charmeuse-nailon on selostettu liitteessä II. Kudos voi olla kiinnitetty patjaytimeen siten, että patja on lämmittämällä tehty takertuvaksi. Pit-35 kittäissivut 6 ja 7 peittävät kudososat voivat olla kiinnitettynä niihin kiinnitysnauhojen avulla, joissa on kiinni-keainetta kummallakin puolella. Kuviossa 2 on esitetty pit-
II
71475 kittäissivun 6 toinen kiinnitysnauha. Tälle kiinnitysnauhal-le on annettu viitenumero 8. Pitkittäissivun 7 kiinnitysnauha vastaa kiinnitysnauhaa 8. Kudoskerrosten 9 ja 10 päälle levitetään kahdesta puolikkaasta 12 ja 13 muodostuva suoja-5 kerros. Kerrokset 12 ja 13 ovat sellaista muovia, joka on läpäisemätöntä ja jonka pinta on sellainen, että bakteerit, aineet ja muut ei-toivotut hiukkaset voidaan helposti poistaa sen pinnalta ja lisäksi että se kestää autoklaavikäsit-telyä. Muovi voidaan kiinnittää kudoksella varustettuun yti-10 meen ydintä lämmittämällä, jolloin pinta tulee taketuvaksi ja takertuvuus kykenee tunkeutumaan kudoksen läpi. Ellei näin tapahdu, levitetään kudos- ja suojakerroksen väliin liimaa tai kummaltakin puolelta liima-aineella varustettu fo-liokerros. Suojakerrosten 12 ja 13 osat koskettavat pitkit-15 täissivuja 6 ja 7 pitkin suurin piirtein reunoistaan toisiaan. Nämä osat voidaan saada tarttumaan kiinni lämmittämällä pat-jaydintä tai käyttämällä kiinnitysnauhaa, joka on kummaltakin puolelta varustettu liima-aineella ja sijoitettu kudos-kerrosten 9 ja 10 ja suojakerrosten 12 ja 13 väliin. Kuvios-20 sa näkyy tämä kiinnitysnauha vain pitkittäissivun 6 kohdalla, jossa kiinnitysnauhalle on annettu viitenumero 11. Suoja-kerrososien 12 ja 13 muodostamat molemmat saumat pitkittäis-sivujen 6 ja 7 kohdalla on peitetty peitenauhalla, jolloin pitkittäissivun 6 puolella oleva peitenauha on saanut viite-25 numeron 14. Sopiva muovi suojakerrosta varten on hyvin elastinen polymeeritilmi. Muovi on selostettu liitteessä III.
Edellisessä esitetty patjaydin on siis neljältä sivulta kudos- ja suojakerroksen ympäröimä, mutta siinä on kaksi päällystämätöntä sivua, nimittäin lyhytsivut 4 ja 5. Nämä 30 sivut ovat päällystämättömät, jotta ilma voisi helposti kiertää patjassa, niin että sen elastisuus säilyy.
Edellisessä on esitetty keksinnön eräs sovellutus, nimittäin patja. Lienee kuitenkin ilmeistä, että keksintöä voidaan soveltaa tyynyihin, auton istuimiin, huonekalujen sel-35 känojiin ja muihin kohteisiin, joissa halutaan välttyä edellä esitettyjen äänien syntymiseltä.
