摘要 |
Movable stand for lampholders comprising an articulated parallelogram member associated with one end to a supporting base and carrying, at the other end, a lampholder. In order to balance the articulated parallelogram friction means are provided acting on a rod member of the articulated parallelogram. The friction means comprise a pair of shoes, arranged opposite each other and having a substantially mating shape to the shape of the rod member whereon the shoes are acting. The pair of shoes is supported by a pair of leaf springs pivoted at their other ends to an opposite rod member to the rod member whereon the shoes are acting.
