Description

Bøyelig og stillbar slangeformet bærearm. Flexible and adjustable snake-shaped support arm.

Oppfinnelsen angår en bøyelig og stillbar slangeformet bærearm av i skruelinjet The invention relates to a flexible and adjustable snake-shaped support arm in the screw line

tett oppviklet ståltråd f. eks. for en elektrisk arbeidslampe. tightly wound steel wire, e.g. for an electric work lamp.

Det er tidligere kjent å bruke en fleksibel stålslange til innstillbare arbeidslam-per og som holdeanordninger for andre gjenstander. Det viser seg imidlertid i prak-sis at anvendeligheten er meget begren-set, idet de kjente slanger enten blir for It is previously known to use a flexible steel hose for adjustable work lamps and as holding devices for other objects. However, it turns out in practice that the applicability is very limited, as the known hoses are either too

korte eller for stive. Dette skyldes en viss short or too stiff. This is due to a certain

sammenheng mellom slangeelementenes connection between the hose elements

gjensidige friksjon og egenvekten av mutual friction and the specific gravity of

slangen. the snake.

Hensikten med oppfinnelsen er å skaf-fe en bøyelig og stillbar slangeformet bærearm som har en egnet mykhet og som The purpose of the invention is to provide a flexible and adjustable snake-shaped support arm which has a suitable softness and which

samtidig er minst dobbelt så lang som en at the same time is at least twice as long as one

Dette oppnås ifølge oppfinnelsen ved This is achieved according to the invention by

at bærearmen er sammensatt av to eller that the support arm is composed of two or

flere etter hverandre i armens lengderetning forløpende ståltrådslangestykker, hvor several steel wire hose pieces extending one after the other in the lengthwise direction of the arm, where

hvert slangestykke, regnet i retning fra each piece of hose, counted in the direction from

Et utførelseseksempel på oppfinnelsen An embodiment of the invention

skal beskrives under henvisning til shall be described with reference to

tegningen. the drawing.

En fleksibel slange for en elektrisk arbeidslampe er sammensatt av tre stykker. A flexible hose for an electric work light is composed of three pieces.

1, 2 og 3 av forskjellig diameter og dermed av forskjellig stivhet. Stykket 1 har størst diameter og stivhet, mens stykket 3 har minst diameter og stivhet. De tre stykker er forbundet med hverandre ved rørmuffer 4 og lodding. Stykket 1 er i den annen ende loddet inn i en rørmuffe 5 som kan festes til en festeanordning 6 for lampen. Stykket 3 er i den annen ende ved lodding for-synt med en rørmuffe 7, som er festet til en lampereflektor 8. 1, 2 and 3 of different diameter and thus of different stiffness. Piece 1 has the largest diameter and stiffness, while piece 3 has the smallest diameter and stiffness. The three pieces are connected to each other by pipe sleeves 4 and soldering. The piece 1 is at the other end soldered into a pipe sleeve 5 which can be attached to a fastening device 6 for the lamp. The piece 3 is provided at the other end by soldering with a pipe sleeve 7, which is attached to a lamp reflector 8.

Den ovenfor beskrevne arbeidslampe har en fleksibel slange som er over dobbelt så lang som tidligere kjente slanger til dette formål, og den er ved hjelp av den for hvert stykke tiltagende mykhet så fleksibel at den kan danne en løkke. The work lamp described above has a flexible hose which is more than twice as long as previously known hoses for this purpose, and it is, by means of its increasing softness for each piece, so flexible that it can form a loop.
