Description

Anordning for røykvarslere. Device for smoke detectors.

Oppfinnelsen angår en frittstående,batteridrevet røykvarsler av den type som monteres i taket på et rom som trenger over-våkning mot brann. The invention relates to a stand-alone, battery-powered smoke detector of the type that is mounted on the ceiling of a room that needs monitoring against fire.

Ifølge oppfinnelsen er en røykvarsler av vanlig type ombygd ved at batteriholder og testknapp er fjernet. According to the invention, a smoke detector of the usual type has been rebuilt by removing the battery holder and test button.

I stedet er en ny batteriholder og en ny testknapp montert i en batteriboks. Instead, a new battery holder and a new test button are mounted in a battery box.

Den ombygde røykvarsleren,som fortsatt inneholder en gass-detekterende og en røykdetekterende del samt en lydalarm-del,monteres som før i taket,mens batteriboksen festes til tilstøtende vegg. The rebuilt smoke detector, which still contains a gas-detecting and a smoke-detecting part as well as an audio alarm part, is mounted as before on the ceiling, while the battery box is attached to the adjacent wall.

Den elektriske forbindelsen mellom den ombygde røykvarsleren og batteriboksen,skjer via en elektrisk ledning med flere ledere. The electrical connection between the converted smoke detector and the battery box is via an electrical wire with several conductors.

Batteribytte og testing av røykvarsleren skjer da fra batteriboksen på veggen. Battery replacement and testing of the smoke detector then takes place from the battery box on the wall.

I tillegg er en snelle med en utdragbar elektrisk ledning bygget inn i røykvarsleren. In addition, a reel with a retractable electrical cord is built into the smoke detector.

Ledningen er da koblet til henholdsvis røykvarsler og batteriboks og kan tilpasses forskjellig takhøyde. The cable is then connected to the smoke detector and battery box respectively and can be adapted to different ceiling heights.

Det finnes to typer røykvarslere på markedet,som er ionisk røykvarsler for ild-brann og fotoelektrisk for ulmebrann. Begge typene er laget for vanlig bruk og har en innebygget batteriholder samt testknapp. There are two types of smoke detectors on the market, which are ionic smoke detectors for fires and photoelectric for smoldering fires. Both types are made for regular use and have a built-in battery holder and test button.

Siden disse røykvarslerene vanligvis er takmonterte,blir batteribytte og testing vanskelig og farlig. Since these smoke detectors are usually ceiling-mounted, battery replacement and testing becomes difficult and dangerous.

Når batteriet er utladet,gir røykvarsleren fra seg en pulse-rende, pipende lyd,noe man vil stoppe så fort som mulig. When the battery is discharged, the smoke detector emits a pulsating, beeping sound, which you want to stop as soon as possible.

Dette kan skje midt i natten,og man griper da gjerne nær-meste stol og klatrer opp for å koble ut batteriet. This can happen in the middle of the night, and you usually grab the nearest chair and climb up to disconnect the battery.

Under slike forhold kan det lett skje fallulykker. In such conditions, falling accidents can easily occur.

Begge de to typene brannvarslere som er omtalt ovenfor,kan bygges om til røykvarsler tilkoblet en batteriboks.Med testknapp og batteri samlet i en veggmontert batteriboks,oppnås at farlig klatring og vanskelig batteribytte unngås. Both of the two types of fire detectors mentioned above can be converted into smoke detectors connected to a battery box. With the test button and battery collected in a wall-mounted battery box, it is achieved that dangerous climbing and difficult battery replacement are avoided.

Med bedre tilgjengelighet,vil varsleren bli testet oftere,og batteribyttet blir ikke utsatt,men vil skje i tide. With better availability, the detector will be tested more often, and the battery change will not be postponed, but will take place in time.

Dermed vil flere ildbranner og ulmebranner bli oppdaget og slukket slik at menneskeliv blir reddet. Thus, more fires and smoldering fires will be detected and extinguished so that human lives are saved.

De forannevnte fordeler oppnås med anordning for røykvars-lere ifølge oppfinnelsen med de i kravenes karakteriserende deler beskrevne trekk. The aforementioned advantages are achieved with a device for smoke detectors according to the invention with the features described in the characterizing parts of the claims.

Anordning for røykvarslere ifølge oppfinnelsen har andre trekk i forhold til patenter i samme kategori. Device for smoke detectors according to the invention has different features compared to patents in the same category.

Anordning for røykvarslere er vist på tegningen,der fig.1 viser en ombygget,takmontert røykvarsler 2,hvor batteriholder med batteri samt testknapp er fjernet. The device for smoke detectors is shown in the drawing, where fig. 1 shows a rebuilt, ceiling-mounted smoke detector 2, where the battery holder with battery and test button have been removed.

En batteriboks 3» som har en batteriholder<*>f0 med batteri k- og en fjærbelastet testknapp 5,er festet til en tilstøtende vegg 6. A battery box 3" which has a battery holder<*>f0 with battery k- and a spring-loaded test button 5, is attached to an adjacent wall 6.

Mellom røykvarsleren 2 og batteriboksen 3»er det til taket 1 og veggen 6 festet en elektrisk ledning 7,som elektrisk sett kobler røykvarsleren 2 og batteriboksen 3 til hverandre. Ledningen 7 har fire innvendige ledere 8,9»10,11 med hver sin farge,noe som forenkler monteringen ved fabrikasjon. Between the smoke detector 2 and the battery box 3, an electric wire 7 is attached to the ceiling 1 and the wall 6, which electrically connects the smoke detector 2 and the battery box 3 to each other. The cable 7 has four internal conductors 8,9»10,11, each with its own color, which simplifies assembly during fabrication.

Fig.2,3,^, viser den ferdigmonterte røykvarsleren 2 ombygget slik,at dens ytre krets består av en snelle 12 som den elektriske ledningen 7 kan vindes på. Fig.2,3,^, shows the fully assembled smoke detector 2 rebuilt so that its outer circuit consists of a reel 12 on which the electric cable 7 can be wound.

På tilvirkningsstedet blir ledningen 7 og dens ledere 8,9,10,11 avisolert i begge ender. At the manufacturing site, the wire 7 and its conductors 8,9,10,11 are stripped at both ends.

Ledningens 7 ene ende føres så gjennom et hull 13 i snellens 12 vegg.Her blir lederene 8,9,10,11 montert til sine respektive monteringspunkter 1*4-, på et monteringsbrett 15,som er festet til snellens 12 yttervegg. One end of the wire 7 is then passed through a hole 13 in the wall of the reel 12. Here, the conductors 8,9,10,11 are mounted to their respective mounting points 1*4-, on a mounting board 15, which is attached to the outer wall of the reel 12.

Fire elektriske ledere 29,30,2<*>f,25,som henholdsvis er koblet til lederene 8,9,10,11 på monteringsbrettet 15,går inn i røyk-varslerens 2 elektroniske område 16,der to av lederene 29,30 monteres til den alarmgivende delen,mens de to andre lederene 2^,25 blir montert til strømforsyningsdelen. Four electrical conductors 29,30,2<*>f,25, which are respectively connected to the conductors 8,9,10,11 on the mounting board 15, enter the smoke detector 2's electronic area 16, where two of the conductors 29,30 is fitted to the alarming part, while the other two conductors 2^, 25 are fitted to the power supply part.

Så blir den elektriske ledningen 7 vindet opp på snellen 12, hvoretter ledningens 7 ledere 8,9,10,11 blir montert til sine respektive monteringspunkter 17 på batteriboksens 3 monteringsbrett 18. Then the electric wire 7 is wound up on the reel 12, after which the wire's 7 conductors 8,9,10,11 are mounted to their respective mounting points 17 on the battery box 3 mounting board 18.

Når røykvarsleren 2 er i drift,går den elektriske strømmen fra batteriboksen 3 på veggen 6,gjennom den vegg-og takmonterte ledningen 7 og fram til den takmonterte røykvarsle-ren 2.Batteristrømmen går videre gjennom den del av ledningen 7 som er igjen på snellen 12,over monteringspunktene 1<*>+ og fram til strømforsyningsdelen i det elektroniske området 16. When the smoke detector 2 is in operation, the electrical current from the battery box 3 on the wall 6 passes through the wall- and ceiling-mounted wire 7 and up to the ceiling-mounted smoke detector 2. The battery current continues through the part of the wire 7 that remains on the coil 12, above the mounting points 1<*>+ and up to the power supply part in the electronic area 16.

Fig.5 viser en prinsipptegning av batteriboksen 3,tilkoblet røykvarsleren 2. Fig.5 shows a principle drawing of the battery box 3, connected to the smoke detector 2.

De elektriske lederene 22,23,som er koblet til batteriet h, er sammenkoblet med lederene 10,11 i monteringspunktene 17 på monteringsbrettet 18. The electrical conductors 22,23, which are connected to the battery h, are interconnected with the conductors 10,11 in the mounting points 17 on the mounting board 18.

Videre er lederene 10,11 sammenkoblet med lederene 2^,25 i monteringspunktene 1^ på monteringsbrettet 15»Furthermore, the conductors 10, 11 are connected to the conductors 2^, 25 in the mounting points 1^ on the mounting board 15"

De isolerte lederene 2^,25 går videre innover i røykvars-lerens 2 elektroniske område 16 og er koblet til røykvars-lerens 2 strømforsyningsdel. The insulated conductors 2^, 25 continue into the electronic area 16 of the smoke alarm 2 and are connected to the power supply part of the smoke alarm 2.

På dette viset leverer batteriet i batteriboksen 3 strøm til drift av røykvarsleren 2. In this way, the battery in the battery box 3 supplies power to operate the smoke detector 2.

Lederene 26,27,som er koblet til testknappens 5 to koblings-punkter 28,er sammenkoblet med lederene 8,9 i monteringspunktene 17 på monteringsbrettet 18. The conductors 26,27, which are connected to the two connection points 28 of the test button 5, are connected to the conductors 8,9 in the mounting points 17 on the mounting board 18.

Videre er lederene 8,9 sammenkoblet med lederene 29,30 i monterinspunktene 1 h på monteringsbrettet 1 5 Furthermore, the conductors 8,9 are connected to the conductors 29,30 in the mounting points 1 h on the mounting board 1 5

De isolerte lederene 29,30 går videre innover i røykvarsle-rens 2 elektroniske område 16 og er der koblet til de to punktene i røykvarslerens 2 detekterende og alarmgivende enhet som før ombygningen ble kortsluttet når testknappen ble trykket inn.Når batteriboksens 3 testknapp 5 nå blir trykket inn,og de to koblingspunktene 28 dermed blir kortsluttet,starter testprosessen med tilhørende lydsignal. The insulated conductors 29,30 continue into the smoke detector's 2 electronic area 16 and are there connected to the two points in the smoke detector's 2 detecting and alarming unit which before the conversion were short-circuited when the test button was pressed. When the battery box's 3 test button 5 now becomes pressed in, and the two connection points 28 are thus short-circuited, the test process starts with the associated sound signal.

Den takmonterte 1 røykvarsleren 2 er utstyrt med et deksel 20, som på siden har en åpning 21 for ledningen 7»The ceiling-mounted 1 smoke detector 2 is equipped with a cover 20, which on the side has an opening 21 for the wire 7"

Mellom snellen 12 og røykvarslerens 2 sentrale del 16, er det bygget inn en avstand 19,som gir snellen 12 en større dia-meter og dermed en større omkrets. Between the coil 12 and the central part 16 of the smoke detector 2, a distance 19 is built in, which gives the coil 12 a larger diameter and thus a larger circumference.

Med større omkrets gis det plass til mer ledning 7. With a larger circumference, space is provided for more wire 7.

Dette gjør at ledningen 7 kan tilpasses forskjellige takhøyder. This means that the line 7 can be adapted to different ceiling heights.

Alle elektriske komponenter skal være ferdig montert fra fabrikk,slik at brukeren kun får til oppgave å innstallere produktet: Først trekkes den nødvendige ledningslengde ut fra røyk-varslerens 2 snelle 12. All electrical components must be fully assembled from the factory, so that the user only has the task of installing the product: First, the required cable length is pulled out from the smoke detector's 2 coil 12.

Deretter monteres røykvarsleren 2 til taket 1,og dekselet 20 settes på. The smoke detector 2 is then mounted to the roof 1, and the cover 20 is put on.

Så monteres ledningen 7 til taket 1 og veggen 6. Then the cable 7 is mounted to the ceiling 1 and the wall 6.

Til slutt monteres batteriboksen 3 med sitt batteri k- til veggen 6,og røykvarsleren 2 er dermed klar til bruk. Finally, the battery box 3 with its battery k- is mounted to the wall 6, and the smoke detector 2 is thus ready for use.

Fig.6-9 viser en praktisk utfoming av batteriboksen 3. Fig.6-9 shows a practical design of the battery box 3.

Fig.6 viser at fire elektriske ledere,26,27,22,23 er koblet til monteringspunktene 17 på monteringsbrettet 18. Fig.6 shows that four electrical conductors, 26,27,22,23 are connected to the mounting points 17 on the mounting board 18.

De to lederene 26,27 er koblet til kortslutningspunktene 28 The two conductors 26,27 are connected to the short-circuit points 28

på testknappen 5«on the test button 5"

Lederene 22,23 er koblet til henholdsvis støpselet 31 og stikkontakten 32,som begge går gjennom og samtidig er festet til en tverrvegg 33 i batteriboksen 3»The conductors 22,23 are connected respectively to the plug 31 and the socket 32, both of which pass through and are simultaneously attached to a cross wall 33 in the battery box 3"

Batteriet k- har en stikkontakt 3^ og et støpsel 35» som utgjør henholdsvis batteriets k- minus - og plusspol. The battery k- has a socket 3^ and a plug 35", which make up the negative and positive poles of the battery k- respectively.

Batteriboksens 3 støpsel 31,med tilhørende stikkontakt 32 The battery box's 3 plug 31, with associated socket 32

og batteriets støpsel 35»med tilhørende stikkontakt 3^»and the battery's plug 35" with associated socket 3^"

har henholdsvis lik form. respectively have the same shape.

Kontaktene på batterisiden og kontaktene på batteriboksen 3, er formet slik i forhold til hverandre,at batteriet *f ikke kan settes inn feil vei. The contacts on the battery side and the contacts on the battery box 3 are shaped in such a way in relation to each other that the battery *f cannot be inserted the wrong way round.

Fig.7,9 viser batteriboksen 3»med et lokk 36,sett fra siden og bakfra. Fig.7,9 shows the battery box 3" with a lid 36, seen from the side and from behind.

Lokket 36 holdes her i åpen stilling ved hjelp av en fjær 37, som er innmontert i hengselet 38»The lid 36 is held here in the open position by means of a spring 37, which is installed in the hinge 38"

Batteriet k- hviler på en forhøyning 39, som er festet til batteriboksens k- bunn. The battery k- rests on an elevation 39, which is attached to the bottom of the battery box k-.

Forhøyningen 39 er noe smalere enn batteriet k-. The elevation 39 is somewhat narrower than the battery k-.

Når batteriet k- skal trekkes ut, skjer dette manuelt. When the battery k- is to be pulled out, this is done manually.

Man får da,på grunn av forhøyningens 39 smalere form i forhold til batteriet *f, et godt grep slik at batteriet lett kan trekkes ut. Due to the narrower shape of the elevation 39 compared to the battery *f, you then get a good grip so that the battery can be easily pulled out.

Batteriboksen 3 har innbygd en batteriholder VOjSom består av forhøyningens 39 overside og to vegger Vi. The battery box 3 has a built-in battery holder VOjWhich consists of the upper side of the elevation 39 and two walls Vi.

Når batteriet k- skal settes på plass,føres det inn i batteriholder en<*>+0. When the battery k- is to be put in place, insert it into the battery holder en<*>+0.

Der vil batteriets k- stikkontakt 3^ og støpsel 35 treffe henholdsvis batteriboksens 3 støpsel 31 og stikkontakt 32 helt nøyaktig. There, the battery's k-socket 3^ and plug 35 will respectively hit the battery box 3's plug 31 and socket 32 exactly.

Elektrisk kontakt mellom batteriet k- og røykvarsleren 2 er dermed opprettet. Electrical contact between battery k and smoke detector 2 is thus established.

Når lokket 36 skal låses,tvinges det manuelt ned til låsen k- 2, hvor mothaken på lokkets 36 fjær<*>f3griper inn i sluttstykket Mf på forhøyningen 39. When the lid 36 is to be locked, it is manually forced down to the lock k-2, where the barb of the lid 36 spring<*>f3 engages in the end piece Mf on the elevation 39.

Når lokket 36 skal åpnes,vippes fjæren<*>f3ut av sluttstykket Mf på forhøyningen 39» When the lid 36 is to be opened, the spring<*>f3 is tilted out of the end piece Mf on the elevation 39»

Da vil fjæren 37 i hengselet 38 overta og tvinge lokket 36 til åpen stilling. Then the spring 37 in the hinge 38 will take over and force the lid 36 into the open position.

Lokket er laget slik, at det slutter tett inntil batteriet<*>f når lokket er låst. The lid is designed so that it closes close to the battery<*>f when the lid is locked.

Lokket 36 lar seg ikke lukke hvis batteriet h ér satt feil inn.Når lokket 36 lar seg lukke,er det en bekreftelse på at batteriet k- er riktig montert. The lid 36 cannot be closed if the battery h is inserted incorrectly. When the lid 36 can be closed, it is a confirmation that the battery k- is correctly installed.

Det gjennomsiktige plastlokket 36,gjør det mulig til enhver tid å kontrollere at batteriet h er på plass. The transparent plastic lid 36 makes it possible to check that the battery h is in place at all times.
