Abstract:
1. A hose comprising: a flexible elongated polyester outer tube member having a first end and a second end, an interior of said outer tube member being substantially hollow; a flexible elongated thermoplastic elastomer inner tube member having a first end and a second end, an interior of said inner tube member being substantially hollow; a metal inlet coupler secured to said first end of said inner and said outer tube members, said inlet coupler defined by a female threaded coupling section rotatably attached to a first threaded annular collar having an inlet flow thru aperture with an inlet tubular extension section extending therefrom and insertable into a first open end of said inner tube member, said inlet coupler having a first ABS plastic ferrule member having an inner wall adapted for placement over said first open end of said inner tube member, said first ferrule member insertable into a first open end of said outer tube member, and a first collar member having a threaded inner surface for releasable securement to said first threaded annular collar sealing said first open end of said inner tube member and securing said outer tube member to said inlet tubular extension section allowing water to flow through said inlet coupler into said inner tube member; a metal outlet coupler secured to said second end of said inner and said outer tube members, said outlet coupler having an outlet flow thru aperture and an outlet tubular extension section extending therefrom and insertable into a second open end of said inner tube member, said outlet tubular extension section formed integral to a second threaded annular collar and an outlet coupling section having an integrally formed rotatable flow restrictor therebetween, a second ABS plastic ferrule member having an inner wall adapted for placement over said second open end of said inner tube member, said second ferrule member insertable into a second open end of said outer tube member, and a second collar member having a threaded inner surface for releasable securement to said second threaded annular collar sealing said second open end of said inner tube member and securing said outer tube member to said outlet tubular extension section allowing water to exit said inner tube member and flow through said outlet coupler; whereby rotation of said integrally formed flow restrictor creates an increase in water pressure between said inlet coupler and said outlet coupler upon the introduction of pressurized water through said inlet coupler to expand said inner tube member longitudinally along a length of said inner tube member and laterally across a width of said inner tube member thereby substantially increasing a length of said inner tube member to an expanded condition within said outer tube member, wherein said elastic based material of said inner tube contracts to a substantially decreased or relaxed length when there is a decrease in water pressure between said inlet coupler and said outlet coupler causing said outer tube member to be gathered into a contracted state.
