| 20100089479 | Self-extending electrical hose - A hose construction adapted for efficiently conveying fluids while extended, but capable of neatly contracting to a fraction of its extended length for storage or transportation, while integrally incorporating lines for electrical requirements. Storage may be within an outer hose and may be triggered via closure of a valve within a nozzle so that negative pressure causes contraction of the folds of the hose. The contracted hose has a length that is a fraction of its normal extended length. The hose construction incorporates a wire reinforcing member which may bias the hose for self-extension and may also function as part of the electrical system. The electrical lines may comprise stranded copper wires to conduct power and/or serve as a remote activation circuit. The hose configuration may have a cover with external folds, which maximizes flow and provides a cushioning outer diameter to prevent damage to the hose. | 04-15-2010 |
| 20100170589 | Portable Flexible and Extendable Drain Pipe - A flexible collapsible corrugated drain pipe has a corrugation structure that permits a tight bending radius and relatively facile collapsing and expansion of corrugations, thereby permitting convenient manipulation and installation of drain pipe and packaging, display, storage and transportation of the collapsed pipe sections. | 07-08-2010 |
| 20100269943 | DUCT STRUCTURE OF A HOLLOW WALL USING A THROUGH-PASS DUCT MEMBER - To provide a through-pass duct member enabling the space in the wall to be more positively shut off against the external space irrespective of the state of the through-pass holes of hollow wall. | 10-28-2010 |
| 20130180615 | Linearly retractable pressure hose structure - A self-actuated linearly retractable and extendible hose ( | 07-18-2013 |
| 20130306184 | Foldable HVAC Conduit and Duct Collar - What is presented is heating, ventilation, and air conditioning (HVAC) ductwork. The HVAC ductwork comprises a strip of material, which is divided into a plurality of circumferential segments by a plurality of living hinges. The living hinges allow the HVAC ductwork to unfold for transportation and storage purposes. The strip of material has both a first locking mechanism and a second locking mechanism that are adapted to interlock with each other at an interlocking site, to create the assembled HVAC ductwork. | 11-21-2013 |
| 20140373961 | APPARATUS FOR FLUID TUBE - A fluid tube is disclosed herein. The breathing circuit tube has a wall which comprises a hollow geometry. The wall defines a passageway with a central longitudinal axis therethrough. The wall is expandable and contractible to adjust a diameter and a length of the passageway. The wall includes one or more corrugations that expand and contract to adjust the diameter and length of the passageway. The corrugations extend between terminal end portions of the wall. | 12-25-2014 |
| 20150083263 | FLEXIBLE WATER PIPE - A flexible water pipe, including: an inner pipe, which can extend or contract when water-filling or dewatering in the flexible water pipe; an outer pipe, which can unfold or wrinkle when water-filling or dewatering in the flexible water pipe; several rings arranged outside the inner pipe; a joint in inflow side, which is used to fasten the inner and outer pipes in inflow side; and a joint in outflow side, which is used to fasten the inner and outer pipes in outflow side; wherein, the outer pipe is arranged outside the inner pipe and the ring. | 03-26-2015 |
| 20150354731 | ANNULAR-PLEATED CIRCULAR BRAID - Aspects of this disclosure can be used to implement a braided cover comprising a plurality of left handed fibers and a plurality of right-handed fibers braided into a hollow tube of fabric. Such a braided cover may be adapted to form a plurality of annular ridges and annular valleys along the longitudinal length of the braided cover when compressed from an extended length to a compressed length. | 12-10-2015 |
| 20160116087 | MULTI-LAYER PRESSURE ACTUATED EXTENDABLE HOSE - A multi-layer pressure actuated extendable 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 means, 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 means and the hose extends. When the fluid source is turned off or disconnected from the hose, internal pressure is reduced and the biasing means exerts a tension force on the hose causing the hose to retract. | 04-28-2016 |
| 20160146379 | MULTI-LAYER EXPANDABLE HOSE - An expandable hose assembly that is able to expand one or more of longitudinally along the length-wise axis of the hose between hose ends and radially, to an expanded state in response to application of at least a minimum fluid pressure to an inner tube of the hose. Once the fluid pressure falls below the minimum fluid pressure, the hose will contract. The hose includes a thermoplastic elastomer inner layer and a slip coating layer thereon having lubricating properties that increases the life of the hose assembly. The hose assembly can include an outer sheath or covering that covers the inner tube and slip coating layer. | 05-26-2016 |
| 20160158479 | APPARATUS FOR FLUID TUBE - A fluid tube is disclosed herein. The breathing circuit tube has a wall which comprises a hollow geometry. The wall defines a passageway with a central longitudinal axis therethrough. The wall is expandable and contractible to adjust a diameter and a length of the passageway. The wall includes one or more corrugations that expand and contract to adjust the diameter and length of the passageway. The corrugations extend between terminal end portions of the wall. | 06-09-2016 |
