Definitions

  • the present invention relates to a diffuser for the air conditioning for air supply and exhaust, in particular by the ceiling, in rooms, in particular of large volume.
  • circular diffusers consisting of a outer envelope, fixed to the ceiling, and provided with deflection to direct the air supply according to the position of these.
  • By adjusting the position of these elements relative to to the outer casing one can thus obtain for example a blowing horizontal which keeps the air to a certain extent on the ceiling or a vertical blowing, with shower effect, as well as blowing intermediaries.
  • All known diffusers have the disadvantage of being made up of a very large number of parts, necessary in particular for assembly between the outer casing and the various elements air deflection as well as to allow adjustment of the air supply the air.
  • the assembly of known diffusers generally requires a large number of manual operations, such as drilling, bolting or riveting, which increases the cost of these diffusers.
  • no safety measures are designed to prevent unintentional detachment of parts, which can lead to accidents, especially during assembly.
  • the object of the present invention is to overcome these disadvantages and to make a diffuser suitable for air conditioning with a minimum number of constituent parts, by means basic and inexpensive operations, performed on machines traditional of a company in the metal manufacturing sector, these parts being themselves made from semi-finished products extremely simple and inexpensive.
  • the first support frame is also welded to the frame.
  • the first support frame is formed by two first metal bands identical stamps which each have a first part flat central unit provided in the center with a first part rounded in shape half-sleeve, a part folded obliquely at each end of the first flat central part and a part folded down at the ends free of each oblique part, the first two bands metallic being welded to each other by their first central part plane while being arranged symmetrically on either side of a first plane of symmetry, so as to form a first complete socket at using their assembled half-sockets, the folded parts being welded to a flange presented by the frustoconical central part of the frame, on the wall side.
  • each second support frame is formed of two second identical stamped metal bands each having a second flat central part provided in the center with a second part rounded in the shape of a half-socket, and, at each end of the second flat central part, a split free end part, the two identical second metal strips being welded one to the other the other by their second flat central part being arranged symmetrically on either side of a second plane of symmetry, of so as to form a second complete socket using their half-sockets assembled, said split free ends being pinched on an edge of a central opening presented by each deflector intermediate.
  • the axis is at least partially threaded and the retaining means cooperating with the axis to allow its displacement relative to the frame are located inside said first socket.
  • the present invention also relates to a method of manufacture of a diffuser.
  • the process does not include drilling, no bolting, no riveting.
  • the parts forming the frames of supports can be simple metal bands which are stamped to the press to take their final shape and which are then welded between them, and possibly further welded to the frame in the case of the first support frame. Extensive process automation is thus obtained by using current equipment in the workshop.
  • the diffuser shown in Figure 1 includes a frame 1 to be fixed on a wall or ceiling not shown.
  • the frame has a flat part 2 at the periphery and present in the center a frustoconical central part 3.
  • This has on the wall side a inlet opening for the air to be diffused which is bordered by a collar 4 coaxial with the inlet opening.
  • the piping necessary for the supply in air can be connected to this flange in a manner not illustrated.
  • An axis 5, tubular and partially threaded in the example of realization, is supported on the frame 1 by means of a frame support 6, so as to extend in a perpendicular direction at the opening of the diffuser, direction which is illustrated by the dashed line 7, and at be able to be moved relative to the frame along this direction.
  • a central deflector 8 of frustoconical shape is fixed to the axis 5 on the side of this one which is opposite the wall.
  • the end of the axle, hollow at this point, can be fixed to the central deflector by a simple crimping using a punch.
  • This example of realization includes an intermediate deflector 9 of frustoconical shape, which also is fixed to the axis 5, by means of a support frame 10. It is disposed between the frustoconical part 3 of the frame and the central deflector 8. It has, in this example, an inlet opening on the wall side, which allows an air passage in its center, and a diffusion opening of the side opposite the wall, which is larger in diameter than the opening of admission.
  • the support frame 6 is, in the illustrated embodiment, formed of two parts 11 and 12, stamped in a metal strip.
  • they are stamped with identical manner and they each have a flat central part 13 provided in its center with a rounded part 14 in the form of a half-socket, and, at each of the ends of the flat central part 13, a oblique folded part 15, at the free end of which is folded a folded down part 16.
  • the two parts stamped in one operation are then arranged symmetrically on either side of a plane of symmetry, by applying their planar central part 13 one against the other and by welding them thus, for example by spot welding.
  • Half-sockets 14 assemblies then form a complete socket 17 in which axis 5 can be passed.
  • one of the two half-sockets 14 has been very slightly stamped with so as to form a tenon 18 which extends radially inside the socket, to a depth approximately equivalent to the depth of the thread presented by the axis 5.
  • the axis can be moved axially in the socket 17, by screwing.
  • the armature support 10 is also formed of two pieces 20 and 21, stamped in a metal strip. These pieces are stamped so identical and each has a flat central part 22, provided in the center with a rounded part 23 in the form of a half-socket. AT each end of this flat part 22 is provided a split part 24 at its free end. In the illustrated embodiment, the parts 24 slits are folded obliquely to the flat central part.
  • the two pieces 20 and 21, folded and split by stamping in a single operation, are then arranged symmetrically on either side of a plane of symmetry, applying their central part plane 22 one against the other and by welding them together, for example by a spot welding.
  • the assembled half-sockets 23 then form a socket 25 complete in which the axis 5 can be passed and fixed, by example by welding or pinching.
  • Axis 5 can also be previously arranged between the two half-sockets of the parts stamped, before welding, and thus be fixed directly to the reinforcement of support.
  • the method of manufacturing a diffuser according to the invention is therefore implemented in the manner next.
  • the partially threaded axis 5 is fixed to the central deflector by example by crimping, as illustrated in figure 2.
  • Strips are folded, cut, split and / or deep-drawn identical by a single stamping operation in a press current, forming the stamped parts 11 and 12 or respectively 20 and 21. These are then joined together so symmetrical and welded to each other, for example by points.
  • the support frame 6 is fixed to the flange 4 of the frame 1 by welding and the support frame 10 is fixed by pinching the edge of the opening intake of the intermediate deflector 9 through the split ends of stamped parts.
  • the split parts provided at the ends of the central parts 22 of stamped parts of the support frame 10 extend in the same plan as the central parts. They have been stamped to form two legs 26 and 27 separated by a slot-shaped cutout. A tab 26 of each slotted end is, during stamping, folded in oblique to the rest of the stamped part. The deflector 9 is then applied against the tab 27, of each split end, not folded during stamping. Then the legs 26 of the split ends are folded so as to extend again in the plane of the central part 22, which causes a pinching of the edge of the intake opening of the deflector 9, in the slot formed between the tab 26 and the tab 27.
  • this process has the great advantage of ease of handling since it boils down essentially by stamping in a single operation each of the parts of the support frames, which are preferably only in number of two for each reinforcement, and by the welding of these between them.
  • the fixing of these support frames to the other parts provides for a simple welding and / or pinching. Since these operations do not do not require the acquisition of special equipment, but only very common welding presses and stations and that the material first used, whether metal bands or strips for the armatures or a threaded tube for the axis, is of a very favorable cost, we obtains a very efficient manufacturing process from a cost point of view. This process also allows, by its automation, an acceleration notable for the rate of assembly.
