Definitions

  • the invention described herein relates to a coupling point for central air extraction systems.
  • 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.
  • 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.
  • 15 denotes a radially-disposed through hole in the tubular element 6, located near to its open front end, which accommodates the plunger 16 of a switch 17 housed in a space existing between the base 2 and the base-insert 5.
  • the switch plunger 16 is seated in the radial hole 15 in such a way as to remain proud of the inner cylindrical surface of the tubular element 6 which accommodates the end of an appliance connecting-hose when inserted.
  • 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.

Claims (4)

1. Vanne de connexion pour systèmes à centrale d'aspiration, comportant
-une base (2) incorporant une douille cylindrique creuse (3) ayant une extrémité avant ouverte;
-un volet plat ou vanne plate (8) coulissant transversalement à travers ladite extrémité avant ouverte, laquelle est pourvue à l'une de ses extrémités d'un trou (9) dont le diamètre n'est pas inférieur du diamètre intérieur de ladite extrémité avant ouverte et qui est guidée et maintenue au ras de ladite extrémité avant ouverte pendant son mouvement de coulissement par un élément de retenue adapté de face sur la base et fixé à celle-ci, caractérisée en ce qu'elle comporte:
-une plaquette de base (5) de forme sensiblement plate laquelle est pourvue au centre de sa face arrière d'un élément tubulaire saillant (6) de forme cylindrique qui pénètre coaxialement dans ledit logement cylindrique creux ou douille (3) avec un jeu prédéterminé et dont la face avant présente un rebord saillant (7) solidaire de la même plaquette et s'étendant en avant coaxialement depuis l'extrémité ouverte de l'élément tubulaire (6); la vanne plate (8) étant apte à coulisser transversalement par rapport à l'extrémité avant ouverte de l'élément tubulaire (6) pendant qu'elle est directement en contact avec le rebord saillant (7) présenté par ledit élément et étant guidée et maintenue au ras dudit rebord saillant (7) au moyen de guides incorporés dans un élément de retenue (11) qui s'ajuste de face sur la plaquette de base (5) et qui est fixé à la base (2);
-un panneau extérieur (12) qui s'adapte fronta- lement sur l'élément de retenue (11);
-la base (2) étant apte à être fixée directement à une paroi ou au côté ouvert d'une boîte (20).
2. Vanne de connexion selon la revendication 1, caractérisée en ce que la vanne (8) qui peut coulisser suivant un parcours vertical, présente une saillie à son extrémité supérieure destinée à lui imprimer ce mouvement, et une lèvre saillante (14) sortant de la périphérie du trou (9) à son extrémité inférieure, laquelle vient en contact avec le rebord saillant (7) sortant de l'extrémité avant ouverte de l'élément tubulaire (6), faisant ainsi fonction d'arrêt mécanique pour déterminer la limite du trajet vers le haut de la vanne (8) et servant à assurer l'alignement du trou (9) avec l'extrémité ouverte de l'élément tubulaire.
3. Vanne de connexion selon la revendication 1, caractérisée en ce que l'élément tubulaire (6) de la plaquette de base (5) comporte un trou de passage disposé radialement (15) qui loge la tige mobile (16) ou un autre élément senseur d'un interrupteur (17) recu dans un espace existant entre la base (2) et la plaquette (5); et en ce que la tige (16) est logée dans le trou radial (15) de telle sorte qu'elle fait saillie de celui-ci par rapport à la surface cylindrique intérieure de l'élément tubulaire (6) de manière à causer l'engagement par contact de la tige (16) avec l'extrémité du tuyau flexible de connexion d'un appareil d'aspiration lors de l'introduction de ce tuyau dans l'extrémité avant ouverte de l'élément tubulaire.
4. Vanne de connexion selon la revendication 1, caractérisée en ce que la plaquette de base (5) comporte une rainure annulaire sur la partie de l'élément tubulaire (6) qui se trouve dans le logement creux (3) situé dans la base (2), de manière à loger une garniture d'étanchéité (19) de type "0-ring" destinée à assurer un accouplement étanche entre les surfaces extérieure et intérieure respectivement dudit élément tubulaire et dudit logement.
