German term

Zugmittel

German to English Tech/Engineering Mechanics / Mech Engineering
In a patent relating to a winding device for raising and lowering a suspended lamp/luminaire: Wie be den aus dem Stand der Technik bekannten Wickelvorrichtungen kann auch hier eine Torsionsfeder verwendet werden, die einer Zugkraft indem Zugmittel das Gleichgewicht hält. Das Auf- und Abwickeln des Zugmittels wierd dann durch eine geringfügige Änderung dieeser Zugkraft--beispielsweise durch leichtes Anheben des Leuchtenkörpers einer Pendelleuchte--in Gang gesetzt.

Thanks very much,

Harold

pulling medium

Since patents are quite abstract, I'd choose something like this. I know it's not pretty, but it's unambiguous if used consistently.

I've never seen these lamps in the U.S. (where most ceiling lamps are mounted in the center of the room); in Germany they are very common, and they are often mounted off-center. The "pulling medium" is usually the electrical cable, but it could also be a wire (in commercial' high-tech style applications) or a (decorative) chain.
It is attached to the ceiling and runs through a doodad (Wickelvorrichtung) that allows you to just push or pull lightly on the lamp which will then "glide" up or down (often used over dining tables.)

P.S.

Please note that the \"Zugmittel\" is not the mechanism (Wickelvorrichtung).

P.S.

The technical term for lamp being \"Leuchte\" in German, there will be more hits if you enter \"Zugleuchte\" to see some examples (I entered \"Zuglampe\" and looked at a taillight for a train on ebay.de...;-) Gewusst, wie!

Actually, looking at your intro to your question, what you call a \"winding device\" is called \"extension\" on websites (of modern examples). As far as I know, there is no active \"winding device\"; most of the momentum is provided by pulling/pushing and, possibly, a spring (which is also mentioned here) or a pulley system.
Can you tell I\'m fascinated by these lamps? I\'ve got one sitting in the basement...
Peer comment(s):

agree Trudy Peters : In a patent it's wise to be as literal as possible

Couldn't agree more, but we also need to understand what the principle(s) of an invention is(are)., hence the lengthy explanation.
agree Rowan Morrell : Hmm, actually you make a good point. Might be a better bet in this context than the suggestions Kim or I have offered.

belt and chain drive

I really don't know if this applies in your situation. That's how Zugmittelgetreibe is translated.

traction mechanism

This is one option suggested by Laixicon, which seems reasonably likely. Hope it helps.

counterweight/counterbalance/countermedium

like your garage door,where a ton of concrete move easily due to the exquisite balance of door and weight(sometimes)

tension means

as said earlier, in a patent it is wise to stick as closely as possible to the original (11y of experience as patent examiner)

pull line

it is obviously a cord or chain as it is "ab- und aufgewickelt"

The line pulled in a counterweight or pulley system is a pull line

Some details for Teresa

The weight of the lamp is suspended by a strong cord (Zugmittel) which runs inside the spiral electrical cable. When the lamp is pulled down, the cord unwinds from the 'Wickelvorrichtung', thereby tensioning a spring inside the WV and thus providing a counter-force to the lamp weight.
There's also a kind of friction clutch inside the WV which releases the spring when the lamp is pulled slightly down again, so that the lamp moves upward again with assistance from the spring.
The whole thing works on the counter-balance or force principle.
