Description
Anordning ved elektrisk lomme- eller blendlykt. Device for electric flashlights or flashlights.
Oppfinnelsen angår en anordning ved The invention relates to a device by
en elektrisk lomme- eller blendlykt av den type hvor batteriet er anbragt i et hus, og pæren bringes til å lyse ved istand-bringelse av en elektrisk krets mellom batteriet og pæren. an electric flashlight or flashlight of the type where the battery is placed in a housing, and the bulb is brought to light by the establishment of an electrical circuit between the battery and the bulb.
Hensikten med oppfinnelsen er å til-veiebringe en lommelykt som kan benyttes til prøvning av sikringer eller elektriske ledninger og kretser for deres kontinuitet ved anbringelse av en eneste hjelpekontakt, idet tilleggskostnadene for denne er ubety-delige når den tas med ved fremstillingen av en ny lomme- eller blendlykt. The purpose of the invention is to provide a flashlight that can be used for testing fuses or electrical wires and circuits for their continuity by placing a single auxiliary contact, as the additional costs for this are negligible when it is included in the manufacture of a new pocket - or headlights.
I henhold til oppfinnelsen er en elektrisk lomme- eller blendlykt som er utstyrt med en utvendig hjelpekontakt for prøving av en sikring eller en elektrisk krets ved anbringelse av denne mellom hjelpekontakten og lyktens hus-, karakterisert ved at hjelpekontakten er utformet som en stift som under prøven trykkes inn i lyktens hus og der først bryter den normale strømkrets til lampen, hvorpå ved en videre inntryk-ning av stiften en strømkrets sluttes til lampen gjennom stiften og over sikringen eller kretsen, hvis denne er hel. According to the invention, an electric flashlight or flashlight which is equipped with an external auxiliary contact for testing a fuse or an electrical circuit by placing this between the auxiliary contact and the lamp's housing, characterized in that the auxiliary contact is designed as a pin that during the test is pushed into the lamp's housing and there first the normal current circuit to the lamp is broken, whereupon by further pushing in the pin a current circuit is connected to the lamp through the pin and over the fuse or the circuit, if this is intact.
Oppfinnelsen skal beskrives nærmere under henvisning til tegningen, som viser et lengdesnitt gjennom en lykt ifølge oppfinnelsen. The invention shall be described in more detail with reference to the drawing, which shows a longitudinal section through a lantern according to the invention.
En elektrisk lykt har et rørformet me-tallhus 10 og et batteri 11, som har en sentral elektrode 12 for tilkobling til en elektrisk lyspære 13, mens den motsatte ende eller omkretsflaten av batteriet 11 danner den annen kontakt. Batteriet er innesluttet i en sylindrisk hylse av papir eller papp, og er i kontakt med huset 10 ved hjelp av en spiralfjær i bunnen av huset på vanlig måte. An electric lantern has a tubular metal housing 10 and a battery 11, which has a central electrode 12 for connection to an electric light bulb 13, while the opposite end or peripheral surface of the battery 11 forms the other contact. The battery is enclosed in a cylindrical sleeve of paper or cardboard, and is in contact with the housing 10 by means of a spiral spring at the bottom of the housing in the usual way.
Pæren 13 holdes i lampeholderen 15, som er montert i sokkelen 16 av isolasjons-materiale, skrudd eller limt til en ende av huset 10. Pæren 13 er i alminnelighet bragt til å lyse ved hjelp av bryteren 24, som The bulb 13 is held in the lamp holder 15, which is mounted in the base 16 of insulating material, screwed or glued to one end of the housing 10. The bulb 13 is generally brought to light by means of the switch 24, which
slutter kretsen til pæren ved å bringe strimmelen 25 i kontakt med strimmelen 29 på lampeholderen 15. closes the circuit to the bulb by bringing the strip 25 into contact with the strip 29 on the lamp holder 15.
Stiften ,26, som er isolert fra huset, stikker ut gjennom huset 10 og er normalt holdt ute ved hjelp av en fjær 27 som er i forbindelse med en flens på stiften. Stiften bærer på innsiden av huset en hjelpekontakt 28, som vil tre i kontakt med strimmelen 29 på lampeholderen 15 når stiften er presset inn mot strimmelen 25 og har bragt denne ut av kontakt med strimmelen 29 og lampeholderen 15, hvorved den normale krets til pæren 13 er brutt. Hvis nå en sikring 23 eller en annen krets er forbundet mellom stiften 26 og huset 10, og stiften presses inn for å bryte den normale krets for pæren 13, vil en ytterligere bevegelse av stiften igjen slutte kretsen gjennom hjelpekontakten 28, hvorved pæren igjen vil lyse hvis kontinuiteten av sikringen eller den annen krets mellom stiften og huset ikke er brutt. The pin 26, which is isolated from the housing, protrudes through the housing 10 and is normally held out by means of a spring 27 which is in connection with a flange on the pin. The pin carries on the inside of the housing an auxiliary contact 28, which will come into contact with the strip 29 on the lamp holder 15 when the pin is pressed against the strip 25 and has brought this out of contact with the strip 29 and the lamp holder 15, whereby the normal circuit to the bulb 13 is broken. If now a fuse 23 or another circuit is connected between the pin 26 and the housing 10, and the pin is pushed in to break the normal circuit for the bulb 13, a further movement of the pin will again close the circuit through the auxiliary contact 28, whereby the bulb will again light if the continuity of the fuse or other circuit between the pin and the housing is not broken.
