Abstract: A highly extendable and retractable dual elastic hose comprises a tubular inner fluid conduit made of an elastomeric material and an elastic tubular outer sleeve of interwoven webbing made out of braided strands of textile yarns wherein embedded a plurality of evenly distributed highly elastic rubber strings extending horizontally along its longitudinal length. The inner tube is secured to the tubular outer sleeve only at an inlet coupler and an outlet coupler. Both the inner tube member and the outer tube sleeve can automatically expand longitudinally up to five times its unexpanded or contracted length resulting from pressurized fluid within the hose. To provide a linearly extendable and retractable dual elastic hose constructed with elastic materials both in the inner tube and the outer sleeve, it shows advantages of an improvement in expandable ratio of the outer sleeve and a reduction of strain forces required for the inner elastic tube to elongate the outer sleeve.

Abstract: A garden hose with an outer flexible sheath of spirally wound and linked turns of sheet material, an inner tube of flexible polymer inside the sheath and end couplers with nipples press fit into ends of the tube and connector mechanisms connecting the couplers to the outer sheath. Each connector mechanism has inner and outer press fit shells at the end of the sheath, with flared ends separated by a washer.
