DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

(10) With reference to the attached drawings and photographs, the cable tube according to the present invention is indicated as a whole with 10 and is structurally composed of the combination of a helical cylindrical spring 11 applied and constrained to a sleeve 12 made of a flexible material, for example an extruded plastic material.

(11) Said spring 11 can, for example, be made of metal wire and can be folded with respect to the longitudinal symmetry axis X of the tube.

(12) As can be clearly seen from the details of FIGS. 6 and 7 of the drawings, the coils 13 of the spring 11 are applied to said sleeve 12, and constrained to it by means of weldings 14.

(13) As can be clearly seen from the details of FIG. 7, the sleeve or mantle 12 can be composed, for example, of strips of plastic material 12a wound on the coils 13 of metal wire of the spring, said coils 13 thus being contained between two partial ty overlapping strips 12a and two subsequent weldings which constrain the strips 12a.

(14) Thanks to the characteristics of foldability and flexibility of the spring 11 and sleeve 12, respectively, and the compressibility of the same spring 11, the tube 10 can be extended between different positions: a shortened non-operating position (FIG. 8), and a plurality of various extended operating positions (FIGS. 1-4). In the shortened position, the coils of the spring 11 are arranged gathered against each other, whereas in the various extended positions, the same coils 13 are spaced from each other. It is evident how the tube 10 can acquire various sinuous positions in space, as clearly shown in the figures.

(15) Characteristically, the lower free end of the tube is provided with a ballasted base 15 (having an adequate weight) which can be freely rested on the floor P in different positions, the most appropriate and desired.

(16) Said base 15 has a generally annular configuration and is provided with at least one radial opening 16 for the passage of cables (not shown), which is in direct communication with the inside of the tube 10.

(17) The upper free end of the tube 10, on the other hand, is provided with rapid connection means 17 to a piece of furniture, for example a table 18, desk or the like.

(18) Said connection means 17 can be composed, for example, of a ring 19 provided with a rapid snap-on coupling 20, that can be freely and removably engaged on a pin 21 of the desk 18.

(19) From what is described above with reference to the figures, it is evident how the cable tube according to the invention can be advantageously used in the most varied operating positions, depending on the point of exit of the cables from the floor and the point of arrival of the same on the work surface.

(20) The cables are also hidden from sight, protected from the external environment, and the cable tube also has a pleasant appearance.

(21) The objectives mentioned in the preamble of the description have therefore been achieved.

(22) The scope of the invention is defined by the following claims.
