Description

July 21, 1959 r. REBUT 2,895,510
TUBULAR CONDUITS Filed June 27, 1955 J. rf/72# United States Patent O W TUBULAR CONDUITS Paul Rebut, Tarare, France Application June 27, 195'5, Serial No. 518,301
Claims priority, application France June 25, 1954 3 Claims. (Cl. 13S-54) The present invention relates to tubular conduits formed from flexible material and having stilfening means.
According to one of its aspects `the invention provides a conduit comprising a tubular sheath formed of flexible material and means including a set of longitudinal reinforcing members and a set of separate circumferential reinforcing members for stilfening the sheath.
According to another of its aspects the invention provides a conduit comprising a tubular sheath formed of flexible material and means for stitfening the sheath.
According to a further aspect the invention provides a conduit comprising a tubular sheath formed of exible material, having inflatable pockets which, when inliated, provide means for stiffening the sheath.
The accompanying drawing shows, by way of non-limitative example, two embodiments of the invention. In the drawings:
Fig. 1 is a view in elevation of a tubular conduit in which lateral tubular elongated members are located outside circular stays;
Fig. 2 is a plan view of the above arrangement;
Fig. 3 shows a dilerent form of tubular conduit comprising elongated reinforcing members located inside circular stays and Fig. 4 is a plan view of the arrangement shown in Fig. 3.
Referring to Figs. l and 2, in lthe sheath 1 'which forms the tubular conduit there are formed longitudinal tubular guides or projecting means 2 and annular tubular guides or projecting means 3. The guides 2 may be distributed at intervals along the length of the conduit 1 as shown or they may be continuous. In the latter case bracing elements 4 can be easily inserted through the `end openings in the longitudinal guides. In the same 'way each annular guide 3 has an opening for the insertion of a split circular member 5 which forms a transverse stay.
The longitudinal guides 2 and the annular guides 3 are formed on the loom in the `course of weaving a Woven conduit or are formed by the use of an adhesive in the case of a tubular conduit formed from a film of synthetic material.
Bracing elements 4 may be formed from tubes, rods or wires of metal or any other material located in the longitudinal guides 2. The split circular stays 5 are inserted in the annular guides 3 by pushing in one of their ends.
Referring now to Figs. 3 and 4, the formation of the longitudinal guides 2 inwards of the annular guides 3 permits the bracing elements 4 to be disposed inside the circular stays 5.
It is also proposed to obtain circular rigidity of the tubular conduit 1 by providing in the longitudinal guides Z and the annular guides 3 inflatable pockets or chambers located next to each other in said guides which can be inflated with lair by means of a network of tubes connecting the pockets.
Alternatively the longitudinal tubular guides 2 and the annular tubular guides 3 can be formed so as to be air- 2,895,510 Patented July 21, 1959 tight. They can then themselves be used as air chambers which can be inflated.
It is obvious that the devices described can be modified in their constructional details in any appropriate manner in order to car-ry the invention into effect.
