Definitions

  • the invention described herein relates to a coupling point for central air extraction systems.
  • Such a coupling point is intended in particular, though not exclusively, to produce an airtight fit between the hose of a suction appliance and the central extraction system, and thus provide the means whereby the former is connected to the latter.
  • the object of the invention described herein is that of providing a coupling point for central air-extraction systems which, whether flush- or surface-mounted, embodies features of a design and of a functional nature which render application simple and troublefree.
  • 1 denotes the vertical wall of a building into which a base 2, fashioned from plastic material and incorporating a centrally-located hollow cylindrical socket 3, is sunk and fixed.
  • base-insert 5 denotes a base-insert of substantially flat shape which is offered to the base 2 and fixed thereto by means of screws 4.
  • the rear of the base-insert 5 exhibits a protruding tubular element 6 of cylindrical shape which is centrally located and fits into the hollow cylindrical socket 3, whilst the front of the base-insert 5 exhibits a protruding rim 7, coaxial and integral with the open front end of the tubular element and extending forward therefrom.
  • a flat shutter 8 located flush against the outermost edge of the protruding rim 7 is designed to slide relative thereto through a vertical path.
  • the shutter 8 is provided at its bottom end with a hole 9 of diameter not less than the internal diameter of the cylindrical tubular element 6, and is guided and held flush against the protruding rim 7 during its sliding motion by means of guides incorporated into a retaining-component 11 which fits over the base-insert 5. Both the retaining-component 11 and the base-insert 5 are made fast to the base 3 by way of screws 4.
  • the shutter 8 which is capable of motion through a vertical path as aforesaid, is furnished at its top end with a projection 13 by means of which to impart such motion.
  • the bottom end of the shutter 8 has a protruding lip 14 embodied such as to make contact, when slid upwards, with the rim 7 at the open end of the tubular element 6; that is, the lip 14 acts as a mechanical stop which determines the limit on upward travel of the shutter 8, and in addition, serves to ensure alignment of the shutter hole 9 with the open end of the tubular element 6 on arrival at this limit.
  • access to the socket and alignment of the shutter hole 9 with the open end of the tubular element 6 are rendered simple, and there is no possibility of the shutter's being separated from its seating when slid upwards to provide access to the socket.
  • the flush fit between the outermost surface of the protruding rim 7 and the rear face of the shutter 8 is such as to provide an efficient, airtight seal.
  • the base 2 is fitted to the open front of a box, or pattress 20.
  • a coupling point according to the invention thus affords simple access to and closure of the socket, with nothing more required than to slide the shutter 8 upwards or down by hand, utilizing the projection 13 as a handle.
