<p>Slidebearing in a circular telescopic pipe with manually or motordriven actuator (4) and a method to avoid visible scratches and slide marks to outer lacuered and finished surfaces on all movable pipe sections in a telescopic pipe, mainly characterized by, that every slidebearing comprises at least two slide elements (1), each provided with one slot (5) and at least three projected segments (6), which slide elements are separated and being assembled into cavities along the outer wall surfaces of all movable pipe sections in the telescopic pipe, and that these slide elements (1), also limiting the total length of the telescoping by cooperating with inwardly free working stops (3, 8), always slide against the inner invisable wall surface of the nearest outer pipe section (2) of the telescopic pipe.</p> |
