Definitions

  • the present invention relates to a device for the retractability of the flexible hose of central vacuum systems.
  • these systems are constituted by a central vacuum unit located in a service room or in a sheltered outdoor place and connected, by means of in-wall tubing, to one or more vacuum inlets into which the flexible hose of adapted cleaning accessories, similar to those of portable vacuum cleaners, is coupled when needed.
  • the aim of the present invention is to overcome the drawbacks of the prior art.
  • the solution proposed with the present invention which is as simple as it is unusual and most of all advantageous, both from the practical standpoint and from the economic standpoint, consists in summary in extending the rigid tubing of the system with an additional fraction which, in addition to having the adequate cross-section and the length that are sufficient to accommodate the flexible hose inside it, is entirely contained within an adapted rigid enclosure which is shaped so that it can be placeable easily wherever necessary.
  • Figures 1 and 2 show a device comprising a housing 1, having a substantially parallelepiped shape, which is flush-mounted in a dividing wall of the room in which to operate with the cleaning accessories inserted in the flexible hose 6 extracted as needed.
  • Figure 2 shows that at least two faces of the housing 1, the ones that are flush with the masonry wall, are provided with a metallic mesh (or equivalent) for the grip of the plaster which, similar to that of housings for retracting sliding doors and for other similar situations, allows the completion of the housing with the same finish as the wall in which it is flush-mounted.
  • the housing in question might be intended for an "exposed" installation and therefore may arrive for installation already esthetically finished to be fixed against a wall and proximate to the tubing 5 of the system to which the tubing 2 of the housing 1 is to be connected.
  • the housing 1 can be made of metallic material, although the adoption of any other material with equivalent characteristics is not excluded.
  • a central vacuum system which comprises a control unit which, via the tubing 5, is stably connected to the tubing 2 since the housing 1 is installed.
  • one end of the tubing 2 communicates with the box 3, from which the flexible hose 6 is to be extracted when needed, while the other end, being designed to be connected to the in-wall tubing 5 that arrives from the vacuum apparatus, according to the embodiment of Figure 1 , ends with a connector of the type of a branch 4 for connection to the tubing 5 that originates from one of the three possible directions of which two, 5a and 5b, are along the wall and one, 5c, is under the floor.
  • the rigid tubing 2 regardless of whether it is connected to the tubing 5 of the system with a branch 4 or with any other connector, has a narrowing of the terminal portion 2a ( Figure 8 ) against which the thicker end 6a (shoulder) of the retractable hose 6 stops when a portion of said hose ( Figures 6 and 7 ) on which it is possible to act manually for extraction remains inside the box 3, such extraction being also necessarily limited by the arrival of said thicker end 6a (shoulder) against the rounded mouth 30 of the hole for access of the flexible hose 6 to the box ( Figure 9 ).
  • Figures 7 and 9 to which Figures 3 and 5 also refer, is termed two-sided here since it allows the extraction and use of the flexible hose 6 in each of the two rooms separated by the wall in which the housing 1 is flush-mounted.
  • the installation of a two-sided housing of the type shown in Figure 3 has the advantage of being executable by orienting in each instance the outlet of the end 2a of the tubing 2 toward the direction of arrival of the tubing 5 of the central system to which it is to be connected.
  • the materials used, as well as the contingent shapes and dimensions may be any according to the requirements and to the state of the art.
