Abstract
A guidable arm for free-positioning lamps of the type with a stand anchored to a base and having a free end holding a lamp head. The guidable arm being made up of two stems which are separated in a parallel manner and which rotate about their own axis with respect to the fixed base. The stems are interconnected by a flexible intermediate spacer and are equipped at their free ends with joints for holding the lamp head. Each of the stems has two goose-neck portions separated from one another and made up of a flexible tube and a sheath having crosswise slits on two diametrically opposed areas and two uninterrupted lateral strips parallel to the axis of the stem. The goose-neck is thus able to bend in a direction orthogonal to the slits and not laterally toward the uninterrupted strips.
