the invention relates to a rotatable link , which may e . g . be incorporated in an upright . the upright may be used e . g . in connection with a support for a card terminal . the rotatable link may be characterized s a rotary friction link . compressive forces caused by a mechanical tension in a pipe are transferred via two first objects to a second object clamped between them . the two first objects are secured and partly built into the pipe , and the second object is rotatable relative to the pipe . the second object constitutes a rotatable link part on which a plated may be welded to provide an upright .
