  • Patent number: 10309560
    Abstract: A multi-layer pressure actuated extendable hose for use in transporting fluids between a source location and an output location includes an extendible hose comprising a biasing element, a sealing layer, and a reinforced cover layer. The sealing layer forms a sealed conduit for transporting the fluids, and the reinforced cover layer on the outside provides radial and longitudinal strength for the sealing layer. The hose can be operated by increasing internal pressure within the hose relative to ambient pressure. When the hose is pressurized by a fluid source, the internal pressure of the hose overcomes the retracting force of the biasing element and the hose extends. When the fluid source is turned off or disconnected from the hose, internal pressure is reduced and the biasing element exerts a tension force on the hose causing the hose to retract.

    Abstract: An extruded bead of thermoplastics material and an extruded tape-like web of thermoplastics material are wrapped in a coordinated manner around a rotating mandrel to continuously form a corrugated, helically reinforced, uniquely constructed “stretch hose” having a thread-like exterior appearance dominated by the web extending in an inclined spiral as it bridges from an outer diameter of each reinforcing coil to an inner diameter of the next-formed reinforcing coil. When the hose is axially compressed, the thin web-defined wall that connects each adjacent pair of reinforcing coils advantageously has one portion that bends or folds radially outwardly, and another portion that bends or folds radially inwardly. Discrete lengths of the hose are treated to minimize stress, to reset memory, and to greatly enhance hose flexibility.

  • Patent number: 9022076
    Abstract: A self-actuated linearly retractable and extendible hose for use in transporting fluids (liquids, gases, solid particles, and combinations of these) between a source location and an output location can be implemented as an extendible hose comprising a biasing element, a sealing layer, and a reinforced cover layer. The sealing layer forms a sealed conduit for transporting the fluids, and the reinforced cover layer on the outside provides radial and longitudinal strength for the sealing layer. The hose can be operated by increasing internal pressure within the hose relative to ambient pressure. When the hose is pressurized by a fluid source, the internal pressure of the hose overcomes the retracting force of the biasing element and the hose extends. When the fluid source is turned off or disconnected from the hose, internal pressure is reduced and the biasing element exerts a tension force on the hose causing the hose to retract.

  • Patent number: 8915266
    Abstract: A flexible stretch hose with a wall which comprises a spirally wound profile (1; 11; 21) in a plastic material. Consecutive windings of the profile are secured to each other by means of a weld. The profile comprises, in cross-section, at least one bottom section (2; 12) and at least one rib section (4; 14; 24), wherein the rib section of the profile, relative to the bottom section, also forms a protrusion of the wall of the hose which gives the hose a predetermined hub strength. The profile comprises an unfoldable section (5; 15; 25) provided in order to be unfolded under the influence of a tensile; force in the axial direction of the hose, thereby allowing an extension of the hose, wherein the unfoldable section comprises at least two profile sections lying loosely against each other, which sections are interconnected at one end.

  • Patent number: 8910667
    Abstract: An expandable hose is provided formed of a sidewall formed of a spirally wound flexible member which defines an axial passageway surrounding a center axis of the formed hose. Both side edges of the flexible member in the spirally wound position are engaged with a cap member which provides a skeletal structure to maintain the axial passageway open and to bias the hose back to a collapsed length from the extended length. A fold formed in the spirally wound flexible member allows for increased distance between the two side edges and an increased maximum extended length. A telescopic pole engaged with the formed hose provides an improved extendable vacuuming tool.

  • Publication number: 20140332108
    Abstract: An extensible-retractable helically reinforced hose is formed by helically wrapping a freshly extruded bead of thermoplastic material about a rotating mandrel to form a helical array of spaced reinforcing coils, and by helically wrapping a freshly extruded thin yet wide web of thermoplastic material so edge regions of the wide web are placed onto and bond continuously with the peripheries of each adjacent pair of the reinforcing coils, with a leading edge region of each new wrap of the web overlying and bonding to a trailing edge region of a prior web wrap. Central portions of each web wrap extend radially inwardly and are sandwiched between adjacent reinforcing coils when the hose is retracted to a minimal axial length.

  • Patent number: 8839823
    Abstract: A metal pipe of single piece construction including a wall formed of a single corrugated metal sheet. The sheet has opposing first and second edges extending longitudinally along the sheet. The wall includes a seam that is formed by abutting portions of the first and second edges. The seam extends helically about and along a length of the wall. The sheet has an interior wall side and an opposing exterior wall side. The interior wall side defines an interior wall surface of the wall. The exterior wall side defines an exterior wall surface of the wall. The sheet has a sinusoidal cross-sectional profile defining 3 corrugation peaks at the interior wall surface and 3 corrugation peaks at the exterior wall surface. The sheet has a flattened sheet width of approximately 27 inches and a finished sheet width of approximately 21 inches. The wall defines a pipe diameter of at least 96 inches.

  • Patent number: 8776836
    Abstract: Hose (70) has a biasing spring (76) extends along the full length. Spring (76) is covered with hose cover material (72) on the outside and hose support layer (74) and hose sealing layer (72) on the inside to form a sealed hose. The invention comprises the improvement of the hose body (layers (72), (74) and (75)) by defining the layers as bowed inward radially between the individual spring coils to create a helical indentation (74b) around hose (70). This helical indentation (74b) causes the hose body materials (layers (72), (74) and (75)) move inward radially when hose (70) is retracted and the coils of spring (76) are forced close together longitudinally. Thus, layers (72), (74) and (75) are folded substantially with spring (76) when retracted, greatly reducing the volume of hose (70) in its retracted position and substantially protecting (72), (74) and (75) from damage by abrasion an puncture.
