Definitions

  • the present invention relates to fixing means for a air diffuser intended to be housed in an opening made for this purpose in a wall such as a false ceiling, and an air diffuser provided with such fixing means.
  • the air diffusers comprise a part rear forming a sleeve for connection to a ventilation duct ending behind the wall, and a front part constituted by a collar front whose dimensions are greater than those of the abovementioned opening, so as to be pressed against a corresponding peripheral zone of the latter by means of fixing means.
  • These diffusers generally have, in their central part, a plurality of trunks of concentric cones spaced apart and directed, of so as to channel the air flow towards the duct or from this according to the field of application of such a diffuser.
  • such a diffuser can be applied, for example, in the heating, ventilation, cooling or heating systems air conditioning, or in that of air extraction systems or smoke, where the air diffuser constitutes respectively an air outlet or a air inlet.
  • the central nucleus will not consist of truncated cones, but by trunks of pyramids.
  • air diffusers according to the invention can also be accommodated in all other kinds of horizontal walls or vertical than false ceilings.
  • the known fixing means intended for such diffusers air are generally made up of fixing bars or rods of suspension that it is necessary to have behind the false ceiling, before installing the air diffuser.
  • this air diffuser on the fixing bar or on the rods for example involves dismantling its central part, then reassembly thereof after fixing.
  • a first difficulty linked to this kind of fixation, lies in the fact that it is necessary to intervene inside the false ceiling itself to put in place these items. This constitutes an operation which is not always easy given the small space available in these false ceilings.
  • Another difficulty consists in the fact that it is necessary to connect the ventilation duct to the diffuser sleeve before its mounting, which does not make it easy to fix it properly diffuser, especially when the sheath is flexible.
  • the object of the present invention is to remedy these drawbacks by offering a solution that facilitates the installation and removal of air diffusers, whatever their diameter and their section, and which can also be applied to diffusers currently manufactured and marketed, without modification and preferably almost without tools.
  • the solution to be proposed must allow all assembly operations or disassembly of the diffuser is carried out exclusively from outside Wall.
  • the object of the invention is achieved by fixing means for a air diffuser intended to be housed in an opening made for this purpose in a wall such as a false ceiling, the diffuser having a sleeve for connection to a sheath and a flange for support on the wall.
  • these fixing means comprise at least two arms, elastically deformable and intended to be attached to the diffuser, so as to extend radially from the diffuser sleeve and to fix the diffuser by elastic pinching of the wall, for example the false ceiling, between the arms and the diffuser flange.
  • the arms When the arms are attached to the diffuser, their free ends are, in the inactive position, distant from the front bezel by a value less than the thickness of the wall and fall within a circle of radius greater than that of a circle in which the opening of the wall is inscribed, so as to ensure the blind fixing of said diffuser.
  • Dimensions and arm profile are determined, in relation to the nature of the material constituent, and in particular with its elasticity, so as to obtain a compromise between the desired elastic effect and sufficient rigidity to support the weight of the diffuser and part of the weight of the sheath.
  • an air diffuser intended to be housed in an opening made for this purpose in a wall such as a false ceiling and having, on the one hand, at the rear, a sleeve of connection to a ventilation duct terminating behind the wall and, on the other hand, at the front, a front flange whose dimensions are greater than those of the opening, so as to be pressed against a corresponding peripheral zone thereof, by means of fixation.
  • the fixing means comprise at least two elastically deformable arms in a radially extending vertical plane from the diffuser sleeve, and whose free ends are, in inactive position, distant from the front bezel by a lower value to the thickness of the wall and fall within a circle of radius greater than that of a circle in which the opening of the wall is inscribed, so as to securing said diffuser by elastic clamping of the wall between the elastic arms and collar.
  • the present invention also relates to the features which will emerge from the description of an embodiment of the invention below and which should be considered in isolation or in all their combinations possible techniques.
  • the air diffuser generally referenced at 1 in Figure 1 is intended to be housed in an opening 2 made for this purpose in a wall 3, constituted for example by a false ceiling made according to a certain distance from a ceiling 4.
  • the air diffuser 1 comprises, on the one hand, at the rear, a sleeve 5 intended to be connected to a flexible ventilation duct 6 terminating between the false ceiling 3 and the ceiling 4.
  • the air diffuser 1 comprises a front flange 7 peripherally connected to the last trunk of cone 8d of a series of trunks of cones 8a, 8b, 8c, 8d of a central core 8 of the air diffuser 1.
  • the external dimensions of the front flange 7, in this case it is a diameter, are larger than the dimensions of the opening 2, so that the flange 7 is pressed against a peripheral zone corresponding to the opening, by means of fixing means.
  • the radius R1 of the flange is larger than the radius R2 of the opening 2.
  • the value of each of the sides of the flange is greater than that of the sides or the diameter of the opening.
  • the means for fixing the air diffuser 1 to the false ceiling 3 are constituted by two arms 9.
  • Each arm 9 has a free end 9a and an end 9b by which the arm is attached or linked to the sleeve 5.
  • the arms are elastically deformable in a vertical plane, extending radially from the sleeve 5 of the diffuser 1.
  • the free ends 9a of the arms 9 are, in the inactive position, distant from the front flange 7 according to a value less than the thickness E of the false ceiling 3 and are part of a circle I of radius greater than that of a circle II in which fits the opening 2 of said false ceiling 3.
  • This arrangement allows the fixing in blind of said diffuser 1 by elastic pinching of the wall of the false ceiling 3 between the elastic arms 9 and the collar 7, without using tools.
  • the radius of the circle I increases more or less when the arms are moved away from the collar 7.
  • the elastic arms 9 are two in number and are arranged radially on either side of the sleeve 5 diametrically opposite.
  • these elastic arms 9 could be three in number or four and be, in this case, distributed radially around the sleeve 5 in forming between them angles of 120 ° or 90 °.
  • a greater number of arm 9 would not be contrary to the invention.
  • the number of arms is limited, like the choice of regular or irregular layout arms around the sleeve, because the size of the opening has a influence on the ease of assembly of the diffuser, and in particular of its introduction into the wall opening.
  • a simple assembly of the air diffuser in the opening described with reference to FIGS. 8a to 8d, does not can be obtained in general only with a reduced number of arms and with a regular or almost regular arrangement, shown in the figures.
  • the elastic arms 9 are reported at their ends 9b on the periphery of the sleeve 5 of inseparable way, for example by means of welds.
  • the arms can be produced by obtaining them from the material lower peripheral edge of the sleeve 5, during the manufacture thereof. This realization in one piece is particularly interesting for the manufacture of plastic sleeves.
  • the elastic arms 9 and 9A are attached to the periphery of the sleeve 5 in a removable manner, by via a collar 10 comprising clamping means acting on the sleeve 5.
  • lugs are provided fixing 11 in the form of a pass, intended for the introduction of the ends 9b of said arms 9 and whose section is substantially corresponding to the section of these.
  • the fixing lugs 11 are made on the collar 10 by a stamping operation. They could also be performed in any other way, for example by reporting them by welding.
  • the same collar 10 or 10A may have three fixing lugs 11 forming an angle at the center of 120 ° between them, plus an additional tab arranged at 180 ° relative to any one of the other three (FIGS. 5 and 6).
  • the collar has an almost regular arrangement of mounting arm and can also be adapted to a two-arm 180 ° system than a three-arm system at 120 °.
  • the support collar 10 of elastic arms 9 is circular and made in two parts 10a, 10b formed for example by complementary metal strips preformed at contour of the sleeve 5.
  • the length of the collar corresponds to that of the periphery of the sleeve, which means that it is generally slightly lower to allow clamping.
  • the two parts 10a, 10b of the collar 10 are connected to each other, on the one hand, by a hinge 12 disposed at one of their ends and, on the other hand, by means of closure and clamping 13 on the sleeve 5 arranged at their other end.
  • the articulation point 12 is constituted by two circular hooks made at the ends of the parts 10a, 10b forming the collar 10, the dimension of one of the hooks being smaller than that of the other so as to allow not only their hanging complementary, but also their articulation, the hooks 12a, 12b being made in different directions to allow their picking.
  • the closing and tightening means 13 of the collar 10 are made up according to the present exemplary embodiment (FIG. 5) by a screw 13a passing through freely a hole (not shown) of a tab 14a, made at one end of the part 10a of the collar 10, and screwing into a threaded hole (not shown) made on another tab 14b at one end of a part 10b of the same collar 10.
  • the blocking of the screw 13a in said threaded hole of the tab 14b is facing each other makes it possible to securely fix the assembly on the sleeve 5 of diffuser 1.
  • the screw and the tapped hole could be replaced by any other system.
  • the 10A collar could be made in a single piece which would be threaded on the sleeve 5 of the diffuser 1, prior to the installation of the sheath ventilation 6 (figure 6).
  • the height h of the collar 10 or 10A must be determined so that once mounted on the sleeve 5 of the diffuser 1, there remains on said sleeve 5 enough space to be able to fit therein correctly and effectively the end of the flexible sheath 6.
  • the dimensions of the arms 9, 9A are determined so as to obtain a compromise between the desired elastic effect and a sufficient rigidity to support the weight of the diffuser 1 and possibly part of the weight of the sheath 6.
  • the elastic arms 9, 9A must have characteristics of flexibility so as to make them deformable, having a spring effect allowing to resume their original shape, while offering resistance mechanical suitable for effectively supporting the diffuser 1.
  • each arm is chosen such that in the stable position of the diffuser, that is to say once the diffuser is installed in the wall, the pinching effect mentioned above is optimum, taking into account the spring effect of the material used, so as to maintain the diffuser in the desired position, without however that their length is a nuisance during installation or disassembly.
  • the length and the shape of said arms may vary depending on the size of the diffuser and the material used.
  • the advantage of such a configuration of the ends 9Aa is to facilitate mounting the diffuser 1, while increasing the pinching effect of the false ceiling 3 between said end 9Aa of the arm 9A and the flange 7 of the diffuser 1, without the effort of deformation of the tab being too great during the mounting.
  • the rounded shape of the end hook offers the advantage of do not damage the suspended ceiling during installation.
  • the length of the arm 9A is such that once engaged in the fixing lugs 11 of the collar 10, it slightly exceeds, in the rest position, the collar 7 of the diffuser 1, so that you can hang it on the edge of the opening 2 of the false ceiling 3 when installing said diffuser 1, then slide it without damage onto the inside face of false ceiling 3 thanks to the curved end.
  • a fastening device as described above lies in the fact that not only does it require no mounting tools, otherwise possibly a simple screwdriver to secure the collar, but it also allows blind mounting without any intervention behind the false ceiling. In addition, it can adapt to any type of existing diffuser without any modification of it.
