Patent ID: 10393291

Abstract:
An expandable water hose assembly comprises a water hose and coupling means. The water hose comprises a flexible outer tube, a collapsible water impermeable flexible inelastic inner tube located inside the outer tube, and an elastic flexible member located inside the collapsible water impermeable flexible inelastic inner tube. The outer tube, collapsible inner tube, and elastic flexible member are movable from a retracted storage configuration to an extended deployed configuration upon application of water pressure within the water hose assembly. The elastic flexible member is in an untensioned state while in the retracted storage configuration and a tensioned state while in the extended deployed configuration. Upon removal of water pressure from within the water hose assembly, the elastic flexible member may return to its untensioned state and applies a retracting force to the hose assembly to urge the collapsible inner tube into a retracted storage configuration.
