Description

Anordning ved lysbøyer. Device at light buoys.

Oppfinnelsen angår en anordning ved lysboyer med batteridrift, hvor en elektrisk strbmkrets i forbindelse med en lampe sluttes når boyen kastes i vannet,idet boyen består av et oppblåsbart hullegeme med en sentral rørform-et åpning, hvori er innfort et på utsiden isolert ror av ledende materiale og som opptar batteriene. Lysbbyen ifblge oppfinnelsen karakteriseres ved at lysboyens ene strbmpol dannes av enden av det sentrale ror, mens den annen strompol dannes av et gjennom rorets bunn isolert kontaktorgan, idet sjovannet slutter stromkretsen mellom de to poler når boyen er kommet i vannet. - The invention relates to a device for light buoys with battery operation, where an electric power circuit in connection with a lamp is closed when the buoy is thrown into the water, the buoy consisting of an inflatable hollow body with a central tube-shaped opening, in which an externally insulated rudder of conductive material and which occupy the batteries. The light buoy according to the invention is characterized by the fact that one current pole of the light buoy is formed by the end of the central rudder, while the other current pole is formed by a contact member isolated through the bottom of the rudder, as the water in the lake closes the current circuit between the two poles when the buoy has entered the water. -

En lysboye ifblge oppfinnelsen egner seg foruten til vanlig bruk i forbindelse med garn og not, også A light buoy according to the invention is also suitable for normal use in connection with nets and nets

godt som merkebbye for å angi en posisjon, når en mann faller overbord. - good as a markbye to indicate a position, when a man falls overboard. -

Et utforelseseksempel på en lysbbye An embodiment example of a light bbye

ifblge oppfinnelsen er vist på tegningen, som viser et vertikal-snitt gjennom boyen. - according to the invention is shown in the drawing, which shows a vertical section through the buoy. -

Boyen består på kjent måte av et elastisk hullegeme 1, fortrinnsvis av plast, som kan blåses opp gjennom en ytre ventil 2. Sentralt gjennom hullegemet 1 forer et i ett med legemet 1 tildannet plastrbr 3, og inn i dette er fort et stålror 4, som opptar batteriene 5. Overst i stålroret 4 er an-bragt en lampeholder 9 med forskruning for en lyspære 10 og en ytre forskruning for en gjennomsiktig lampekuppel 11. Nederst er roret 4 lukket av en plate 6 med en sentral åpning hvori en isolerende plastpropp 7 er innsatt. Gjennom proppen 7 er inn-festet en skrue med et ringhode 8, av elektrisk ledende materiale, som f.eks. stål. Skruen 8 er påskrudd en mutter som ligger an mot det nedre batteri 5. I rorets 4 bunn er omkring mutteren ifylt isolerende aralditeplast e.l. - The buoy consists in a known manner of an elastic hollow body 1, preferably made of plastic, which can be inflated through an external valve 2. Centrally through the hollow body 1 is a plastic tube 3 formed in one piece with the body 1, and into this is a steel rudder 4, which accommodates the batteries 5. At the top of the steel rudder 4 is a lamp holder 9 with a screw-in for a light bulb 10 and an outer screw-in for a transparent lamp dome 11. At the bottom, the rudder 4 is closed by a plate 6 with a central opening in which an insulating plastic plug 7 is inserted. A screw with a ring head 8, made of electrically conductive material, such as e.g. steel. The screw 8 is screwed onto a nut that rests against the lower battery 5. In the bottom of the rudder 4, insulating araldite plastic or the like is filled around the nut. -

Stålrbrets 4 ende 4a danner den ene kontaktpol, mens den annen kontaktpol dannes av det gjennom bunnen 6 innsatte kontaktorgan 8, idet roret 4 rager så mye ut av boyen 1 at sjbvannet alltid kommer i kontakt med roret 4. - The end 4a of the steel rib 4 forms one contact pole, while the other contact pole is formed by the contact member 8 inserted through the bottom 6, the rudder 4 protruding so much from the buoy 1 that the seawater always comes into contact with the rudder 4. -

Kontaktorganet (polen) 8 er i eksemplet utformet som et ringbye som tjener som taufeste for et garn eller en not. - In the example, the contact member (pole) 8 is designed as a ring which serves as a rope attachment for a net or a groove. -

Claims

,-:-:'l. Device for a light buoy, where an electric current circuit in connection with a lamp is closed when the buoy enters the water, and where the buoy consists of an inflatable hollow body with a central tube-shaped opening, in which an externally insulated rudder of conductive material is inserted and which accommodates the batteries, characterized in that one current pole of the light beam is formed by the end (4a) of the central rudder (4), while the other current pole is formed by a contact member (8) isolated through the bottom (6) of the rudder (4) as the sea water completes the current circuit between the two poles (4a ,8) when the buoy has entered the water. -

2. Device for light bowing according to claim 1, characterized in that one contact pole (8) is designed as a rope attachment for a groove or a net. -
