Fixing unit for air supply joint for vacuum cleaner - forms air path by rigid tube and freely-moving torsionally stiff connection between two tubular parts

摘要

The line shaped flexible element (7-11) e.g. ball chain for two movement axes (5,6) displaced 90 deg. respectively from one side of the joint, starts from a first anchorage point (8) returns via the first axis point of the respective movement axis (5,6) to the opposite side, i.e., on the half circumference (10) to the opposite lying second axis point of the same axis to the initial side to a second fixing point (12). The first and the second anchor points (8,12) of the flexible element are arranged for the first movement axis (5) about 180 deg. in the circumference of the initial side, displaced at the same distance (A) to the second movement axis (6) and vice versa. USE/ADVANTAGE - Fixing unit for joint connection. Each setting attained by simple bending or displacement of joint.
