Stand pipe for e.g. floor lamp, has amplifying units held in internal space of pipe by guiding devices, where pipe has inner profile with profile unit for guiding amplifying units, and profile has channels for inserting connecting units

摘要

The pipe has a set of amplifying units (20) held in an internal space of an outer pipe (10) by a set of form-fitted guiding devices, where the outer pipe has an inner profile with a profile unit for guiding the amplifying units. The amplifying units are arranged in a transverse section perpendicular to a longitudinal axis, where the outer pipe is made of aluminum, and the amplifying units are made of steel. The inner profile has channels at an end of the outer pipe for inserting connecting units. An independent claim is also included for a construction set for a stand pipe.
