ABSTRACT:
A flexible, adjustable tube which comprises a tubular body of pleated asymmetrical accordion fold configuration wherein each pleat is defined by a thrust cone wall segment and a Belleville washer-like wall segment. The narrower ends of the two wall segments are integrally connected to form an annular articulation about a central axis and the wider ends of the individual Belleville washer wall segments of each pleat are integrally connected to the wider ends of the thrust cones of the next succeeding pleat, to form an annular articulation about the central axis. The Belleville washer-like wall segments of each pleat are proportioned to be snap shifted through the articulation of same to the thrust cone of the next adjacent pleat, for shortening or lengthening the tube. Similar partial snap shifting of the individual Belleville washer wall segments may be effected, for angulating the tubular body, by canting the thrust cone wall segment of a selected pleat sidewise.
