Extensible And Retractable Conduit Patents (Class 15/315)
  • Patent number: 10433690
    Abstract: A central vacuum cleaning system includes an inlet valve mounted at various locations in a structure connected to the inlet end of a vacuum conduit. A section of hose is slidably mounted within the conduit and extends from the inlet valve for cleaning an adjacent area. A pair of seals within the inlet valve retains a nozzle handle mounted on the end of the hose in a stored position when the hose is in a retracted position and provides an air seal between the handle and vacuum supply conduit. A locking mechanism mounted on one embodiment of the inlet valves automatically locks the hose in a selected extended position when manually pulled from the inlet valve. A mounting bracket enables the inlet valve to be mounted at various locations in the structure and a pair of seals enables the inlet valve to be open to the ambient atmosphere.

  • Patent number: 7549448
    Abstract: A linearly self-actuated hose for use in transporting fluids (liquids, gases, solid particles, and combinations of these three). Hose (30) has a biasing spring (36) that extends along its full length, and can comprise single or multiple springs and/or multiple diameter spring coils. Spring (36) is covered with hose cover material (32) on the outside and hose cover material (34) on the inside to form a sealed hose and are bowed inward or outward radially between the individual spring coils depending on the intended use of hose (30) to give the cover materials room to move out of the way when the hose retracts and the coils of spring (36) are forced close together. The Linearly Retractable Hose is operated by changing internal pressure within the hose relative to the ambient pressure on the exterior of the hose. Control of fluid pressure within hose (30) is what allows the hose to operate as an automatically extendable and retractable hose. The biasing of spring (36) depends on the type of use for the hose.

  • Patent number: 7010829
    Abstract: A retractable hose central vacuum cleaning system comprising a retractable vacuum hose configured to retract through a valve assembly, into a system vacuum pipe responsive to the vacuum communicated from a vacuum source. The valve assembly comprising a static valve seal adapted for coupling a system vacuum pipe to the vacuum hose to create a substantially air-tight sealed communication between the system vacuum pipe and the vacuum hose. The static valve seal being adjustable from a first unsealed configuration where the vacuum hose can move freely through the valve assembly and system vacuum pipe, to a second sealed configuration where the vacuum hose is in sealed communication with a system vacuum pipe, and where the vacuum hose is substantially fixed in relative position to the valve assembly. Wherein movement from first configuration to the second configuration locks the vacuum hose in place relative to the valve assembly.

  • Patent number: 6560816
    Abstract: A central vacuum cleaner system is mounted within the wall of a building and includes an in wall mounted enclosure. The enclosure has a front door moveable between open and closed positions, and a vacuum cleaner bag holder in the enclosure moveable between closed and open positions, so that the door engages the holder when the door is moved from the open to the closed position, thereby moving the bag holder from its open to its closed position. A conduit extends from at least one remotely located hose inlet connector to a distal end within the enclosure, with the distal end being inserted into a bag carried by the bag holder when the bag holder is moved to the closed position. A vacuum source, preferably within the enclosure, is adapted to draw air from the inlet connector into the enclosure.
