Description

CONNECTION SYSTEM BETWEEN AN AIR TUBE AND A ROOM

  END OF A VENTILATION SYSTEM,

CONNECTED TO SAID ROOM

  The present invention relates to a connection system.

  sound between an air chamber and an end piece connected to the latter, preferably a valve of a ventilation installation. In the solutions of the prior art, air is delivered to a room thanks to the fact that the air penetrates, by borrowing

  a tube, in an air chamber which it crosses to reach

  nir in an end piece, preferably an air distribution valve, through which it flows into said room. In these structural arrangements, a problem lies

  in adjusting the correct height position of the support

  Pope. The tubular lines of the ventilation system

  lation, and air chambers connected to them, are found

  wind at a determined height. However, the position of the sou-

  Pope is defined by the underlying structures of the ceiling and by the imperatives of space. Said pipes, and said chambers connected thereto, cannot be

  made with easy height adjustment. It's for-

  what the integration of the valve occupying the top position

  correct, in the room, was carried out using tubing-

  separate connection elements that are difficult to adjust. In determined solutions, the end piece must be as close as possible to the air chamber; on the other hand, in certain specific mounting cases, it must be possible to install the valve at a significant distance from the chamber

  air, via an advantageous tubular connection.

  In the solutions of the prior art, it was therefore

  necessary to interpose, between the valve and the valve chamber

  air distribution, separate pipes through which said valve could be installed with sufficient

distant from said room.

  The use of the above-mentioned additional tubes has raised difficulties since the structure must be leaktight, and connection areas subject to leaks are prohibited.

  The present application proposes an improvement in the technology

pic exposed above.

  In accordance with the invention, this object is achieved by the

  causes the system to have a separate connector sleeve

  can be installed, relative to the chamber housing

  air distribution, so that the tubular part of the

  said sleeve protrudes outward beyond the chamber; and

  by the fact that said connection sleeve can be installed

  as a variant, so that its tubular part penetrates

  in the internal space of the air chamber, the alternating position

  mentioned sleeve of said sleeve allowing a wide adjustment stroke allowing the end piece of the ventilation installation, preferably a valve, to be connected by its

  tubing for connection to the tubular part of said sleeve.

  According to other characteristics of realization before-

geuses of the invention:

  the connection sleeve preferably comprises a part

  annular clamping tie and a tubular part connected to the latter; quick connections, by which the connection sleeve can be removably connected to the housing of the

  air chamber, can be advantageously installed on the-

  said chamber case all around the circulation hole-

air;

  - preferably, several rapid connections are made

  mounted all around the air circulation opening in the air chamber; and each fast connection can

  conveniently include an arm to which rotation may be im-

  award-winning in such a way that said arm comes to be pressed against the annular clamping part of the connection sleeve and

  press this part against the surrounding packing

  rant said orifice made in said chamber, thereby imparting a seal to the connection; - the arm for quick joining can advantageously be

  consist of a first segment and a second form segment

  mant an angle with respect to the latter, as well as a third segment extending in the direction of said first segment; in

  in addition, the aforementioned third segment of said arm can judiciously-

  ment bear against the annular clamping part of the connection sleeve when establishing the connection; and said arm can advantageously rotate about an axis; - preferably, the orifice is surrounded by a lining

  sealing having a groove through which said lining

  ture is placed against the circular edge of the opening

ture; and

  - the end piece of the ventilation, preferably a

  pope, can be conveniently attached to the tubular part of the connecting sleeve via the connecting tube connected to said valve, so that said valve tubing enters said tubular part of the sleeve; the outside diameter of the valve tubing is preferably slightly less than the inside diameter of the tubular part of the sleeve; the outside diameter of

  said tubular piece is preferably slightly inferior

  laughing at the inside diameter of the air circulation opening in the air chamber; the connecting pipe of

  the valve can judiciously comprise, on its external surface

  upper, a groove housing an annular seal

  is lying; and, advantageously, rivets, screws or the like pass through said tubular piece and said

  tubing, and connect the latter to each other.

  The connection system according to the invention is provided with a separate connection sleeve which can be connected to the

  air distribution chamber housing, free

  maple, all around the air circulation opening

  in said room. Due to the use of the pre-

  cited, the end piece distributing the air, preferably a valve, can be connected to the chamber in such a way that said valve can be easily brought to different positions relative to the connection sleeve. The connecting pipe of the valve enters the tubular part of said sleeve. The inner diameter of this sleeve is significantly larger

  than the outside diameter of the tubing connected to the valve.

  The valve tubing further includes a groove

  in which an annular seal is integrated

  rigged. When the desired valve position is reached,

  the connection sleeve and the connection pipe of the

  said valve are, for example, connected to each other by

  screws or rivets passing through these tubular elements.

  Furthermore, the diameter of the circulation orifice

  of air in the air distribution chamber is sensitive

  considerably larger than the outside diameter of the tubular part

  connection sleeve area. Said sleeve can thus be

  animated by a rotation, so that its tubular part comes to

  bend against the inside of the chamber. In addition, in

  the above-mentioned structural embodiment, the sleeve can be connected

  strung to the chamber correspondingly, by the annu-

  clamping area, using rapid fastening. The solu-

  tion that the tubular part of the sleeve engages inside the chamber, provides a greater stroke of

  adjusting the height position of the valve.

  The invention lends itself not only to devices for

  air distribution in which air, coming from canali-

  tubular sations, runs through an air chamber and a valve connected to the latter, to reach the air distribution chamber from which it is directed into the room by crossing the end piece, preferably a

  valve; but the solution can also be applied to a dispo-

  air exhaust system in which air from the room passes through the end piece and enters the room

  air distribution, to then be evacuated in a cana-

Tubular outlet connection.

  The system also allows for practical application

  in which the connection sleeve is completely sup-

  awarded and the valve is directly installed, through its body,

  on the inner tube housing.

  The invention will now be described in more detail, by way of non-limiting examples, with reference to the appended drawings in which: FIG. 1A illustrates the connection system according to the invention, between an air chamber and a valve connected to the latter, said system comprising a sleeve separate from

  connection. In the figure, the parts forming part of the system

  the position in which the tubular part of the coupling sleeve

  cord enters the internal space O of said chamber; and Figure 3 illustrates the practical application of the system

  in accordance with the invention not comprising a coupling sleeve

  dement, application in which the valve is directly fixed to the casing of the air chamber (by fixing means not shown), the connecting pipe of said valve

  enters the internal space O of said chamber, and the lining

  sealing structure 15 seals between said valve

and said chamber.

  FIG. 1A shows a connection system 10 according to the invention, between a valve 16 and an air chamber 11 connected to the latter, for adjusting the distance between said chamber 11 and said valve 16 (in FIG. 1C). In FIG. 1A, the parts constituting the system are illustrated separately the

  each other. In accordance with FIG. 1A, the system 10 in-

  globe the air chamber 11 and an orifice 12 for air circulation

  which is practiced in it. System 10 includes a man-

  connection piece 13. Said sleeve 13 is a compres-

  nant an annular clamping part 13a1 and a tubular part 13a2 connected to the latter. As illustrated, the

  sleeve 13 is connected to a housing R of chamber 11 for dispensing

  tion of air, by its clamping part 13a1, by means of quick connection means or quick connections 14a1, 14a2 ... Said quick connections 14a1, 14a2 ... are stop pieces made up of an arm rotary 14b can be pressed against the clamping portion 13a1 of the sleeve 13 when attaching said sleeve 13 to the housing R. The chamber 11

  has flow openings A1 and A2. A step channel

  of air is connected to the opening A2 and there is connected, to the opening A1, the sleeve 13 by means of which is

  attached the valve 16 which may consist of a shut-off valve

air inlet or outlet.

  Fast connections 14a1, 14a2 ... including one

  plurality is preferably provided, are arranged with distribution

  uniform tion around the circular orifice 12 for air circulation. They are preferably four in number (14a1 to 14a4). The opening A1 is provided with a seal

  on an edge A1 'delimiting it, the arm 14b of the solidarisa-

  tion can then be rotated towards the annular clamping part 13a1 of the connection sleeve 13, so that it exerts pressure against the lining 15 of said part 13a1. This gives a tight connection.

  In the embodiment according to FIG. 1A, the man-

  connection piece 13 is firstly tightened against the casing R of the air chamber 11 by means of the fastenings

fast 14a1, 14a2 -

  In accordance with FIG. 1B, the connection sleeve 13 is fixed to the air chamber 11 by means of the fastenings

fast 14a1, 14a2 ...

  According to FIG. 1C, the valve 16 is placed on the tubular part 13a2 of the connection sleeve 13, so that a connection tube 16a1 of said valve 16

  enters the internal space of said part 13a2 of said man-

  chon 13. Thus, the outside diameter D1 of the pipe 16a1 of the valve 16 is slightly smaller than the inside diameter D2 of the tubular part 13a2 of the sleeve 13. The outside diameter

  D3 of said piece 13a2 of said sleeve 13 is, for its part,

  considerably smaller than the internal diameter D4 of the air circulation orifice 12 formed in the casing R of the air chamber

  11. In the plane of the annular clamping part 13a1 of the man-

  chon 13, said annular part is perpendicular to the axis

  median of the tubular part 13a2 of said sleeve 13.

  FIG. 1D is a representation, on an enlarged scale,

  fast joining 14a3. In accordance with the illustration

  tion, said rapid connection 14a3 comprises an arm 14b.

  Said arm 14b consists of a segment 14c1 and a segment 14c2 describing an angle, essentially a right angle with respect to the latter, as well as a third segment 14c3 extending in the direction of said segment 14c1 . A 14d1 rivet, crossing

  a hole f drilled in the segment 14c1, is fixed to a part

  additional riveting 14e1 located on the housing R. As it-

  glossy in the figure, the arm 14b is rotated around an axis X, so that the annular clamping part 13a! of the connection sleeve 13 is applied against the segment 14c3, and that said clamping portion 13a! is firmly retained against the seal 15 using said segment. Preferably, said lining 15 is an annular lining which

  surrounds the orifice 12 and is put in place by an annular groove

  area U1, on the circular edge A1 'of the opening A1. The garni-

  ture 15 extends substantially towards the inner side of the ori

  fice 12 from edge A1 'of opening A1.

  Figure 1E shows one of the extreme positions of the re-

  setting the distance which is illustrated in figure lB, is based

  on the position of the connection sleeve 13 and allows

  define the maximum distance between the valve 16 and the housing R of the air chamber 11. The valve 16 is, for example, fixed to said

  sleeve 13 by rivets 17a1, screws or the like

  res. Said rivets 17a1, screws or similar members pass through the tubular walls of the connection tube 16a1 of the

  valve 16, and of the tubular part 13a2 of the sleeve 13.

  mement to the illustration, said tube 16a1 of the valve 16 has a groove U2 in which is housed a gasket

  sealing ring 16b1. Said packing 16b1 comes to

  bend against the inner surface of part 13a2 of the sleeve

  13 and seals the connection surfaces.

  Figure 1F shows the other extreme position of the distance adjustment which is illustrated in Figure 1A and is based on the position of the connecting sleeve 13, the extreme position in which the distance between the valve 16 and the air chamber

It presents its minimum dimension.

  FIG. 1G is a detailed representation, in pers-

  pective, of the arrangement of the sealing gasket 15 on

the edge A1 'of the opening A1.

  FIG. 2A illustrates the adjusted position in which the connection sleeve 13 is driven by a rotation capable of causing its tubular part 13a2 to penetrate into an internal space O of the air distribution chamber 11. Said part 13a2 of said sleeve 13 thus engages, in the internal space O of chamber 11, crossing the orifice 12 for air circulation. The figure shows the maximum setting of the distance between the valve 16

and the housing R of the chamber 11.

  FIG. 2B shows the minimum adjustment of the distance between the valve 16 and the housing R. In the embodiment

  Figures 2A and 2B also, said housing R and said sub-

  pope 16 are connected to each other by pieces of solidarity

  such as 17a1 rivets, for example, or the like. FIG. 3 illustrates the practical application of the system in which no connection sleeve 13 is used and the valve 16 is put in place, by its connection pipe 16a1, in such a way that it enters the internal space 0 of

the inner tube 11.

  It goes without saying that many modifications can be made to the system described and shown, without departing from the

part of the invention.
