Abstract
A lockable friction joint includes a first joint member with a first arm member and a second joint member with a second arm member, the first and second joint members each having an inner friction surface and pivotal connecting projections. A friction adjustment device includes an adjustment element on an outer surface of the second joint member, and a fixating element on an outer surface of the first joint member. A plurality of friction discs are adjacent each other and between the inner friction surfaces of the first and second joint members, whereby friction between the friction discs is adjusted by the adjustment element. Each friction disc has at least one friction surface acting on an adjacent friction surface of another element of the friction joint and each friction disc is pivotally coupled to at least one other element of the friction joint.
