Definitions

  • the invention relates to an air distributor according to the preamble of claim 1.
  • Such air distributors are used to ventilate work, living and other common rooms, or for ventilation and air conditioning. They usually have a box which, with a length of usually one to two meters, has a rectangular cross section in the order of magnitude of half to a few dm 2 . At the bottom there is a slot running along the box, to which the air outlet element connects.
  • the air outlet element is often a plastic or metal - in particular light metal - extruded (the expression extrusion here should also include the extrusion of plastic with) profile, which is provided on the underside with adjustable or fixed outlet nozzles depending on the circumstances.
  • the distribution box serves the purpose of that to distribute air to be ventilated or to be air-conditioned (hereinafter, for the sake of simplicity, we will only speak of ventilation) over the entire length of the outlet element without a noticeable loss of pressure.
  • the air then flows uniformly from top to bottom over the entire length of the outlet element and leaves the outlet element at the bottom thereof.
  • Such air distributors are generally known and common.
  • the box is made of sheet metal, mostly sheet steel. Examples of the air outlets used here are described in DE-OS 25 36 293 and DE-PS 23 46 108.
  • the invention aims to improve the known air distributors according to the preamble of claim 1 in such a way that the outlay required for their manufacture and assembly is substantially reduced and, moreover, the usability of the same becomes more flexible, that is to say the air distributors can be more easily adapted to different uses.
  • an air distributor according to the invention essentially consists of only three main parts, namely a left side part, a right side part and the outlet nozzle strip.
  • the production of these three parts in the extrusion process and the cutting to the desired length is simple and inexpensive.
  • the cost of producing a meter of air distributor according to the invention is less than half the cost of a meter of comparable air distributor according to the prior art with a distribution box folded from sheet metal. Since the manufacturing costs are a direct measure of the manufacturing effort, there is considerable technical progress here.
  • the 3 - Installation of the air distributor is extremely simple. The two side parts only have to be joined together. Then the outlet nozzle strip must be pushed on or snapped on.
  • the outlet nozzle strip must exert a sufficiently large clamping force on the lower edges of the side parts.
  • connection profiling it is e.g. possible to design the upper connection profiling so that it resists swiveling of the side parts around the connection profiling as an axis and bulging the side parts in whole or in part so that the clamping force exerted by the outlet nozzle strip tightly tightens the lower edges of the side parts - or more precisely - in the holds desired location.
  • the design is such that the outlet nozzle strip clamps the lower edges of the side profiles, a spacer, which can be fixed separately or also on one or both of the two side parts, is provided in the region of the transition from the distribution box into the outlet element, via which the side parts are supported on each other.
  • a spacer By means of such a spacer, the necessary tension can be introduced into the air distributor, which ensures that the upper and the lower connection of the side parts sit sufficiently tightly together.
  • a major advantage of the air distributor according to the invention is that a large number of differently sized distribution box cross sections is possible with a few components through different combinations of the same.
  • two wide side panel profiles can be combined to form a wide distribution box
  • one narrow and one wide side panel profile can be combined to a medium-sized distribution box
  • two narrow side panel profiles can be combined to form a narrow distribution box.
  • a stock of only two different profiles, two of which form the box, therefore makes it possible to produce three different profile box cross sections. With three different profiles, you can already produce six different box cross-sections.
  • the outlet nozzle strip has an essential function with regard to holding the air distributor together.
  • the outlet nozzle must hold the lower free edges of the two side walls delimiting the air outlet element together and, if necessary, also at a distance. For this reason, an embodiment according to claim 2 is preferred.
  • the outlet nozzle is advantageously designed according to claim 4.
  • Such profiling of the outlet nozzle strip brings the further significant advantage that it is particularly well suited for the training according to claim 3.
  • the design according to claim 5 represents a particularly advantageous combination of a production-favorable connection of the outlet nozzle strip and side parts on the one hand with a favorable air duct inside the air distribution element. Another major advantage of such a design is that the air outlet openings in the air outlet nozzle can be produced by punching .
  • a throttle element is normally provided at the transition from the distribution box to the outlet element. According to the invention, this throttle element is advantageously created according to the teaching of claim 6.
  • Another training option for the throttle element is characterized in claim 7.
  • This design can also be combined with one according to claim 6, for example by forming a fixed perforated plate according to claim 6 and below it a slidable perforated plate according to claim 7, the passage openings in the fixed web and depending on the sliding position of the slidable plate can be completely or only partially aligned in the displaceable sheet metal or can also be completely closed when the air outlet element is not required.
  • connection profiling is preferably arranged on the top of the distribution box according to claim 8. This ensures that the two side parts of the air distributor are no longer of different sizes than necessary and in particular also facilitates the combination of differently sized side parts for the purpose of producing distribution boxes of different cross-sections with as few different elements as possible.
  • connection profiling on the upper side can be brought about by appropriate edge configurations of the two parts, for example as is customary with sheet piling profiles.
  • connection profiling is preferably designed according to claim 9. This makes it possible to get by with two completely identical side profiles with a symmetrical design of the air distributor and also to connect side profiles of different widths, since the same side part is chosen in the configuration according to claim 9 can be used either right or left.
  • the distribution box is to be provided on the inside with a heat insulation layer, for example made of foam or glass wool
  • the air distributor is advantageously designed according to claim 10.
  • the stop ribs hold the thermal insulation layer securely in place both during assembly and during later operation.
  • the stop ribs can be extruded in one piece with the side parts.
  • the stop ribs can also be separate components which are inserted into corresponding grooves or between the side parts.
  • a further preferred embodiment of the invention is characterized in claim 13.
  • the air distributor 1 shown in Fig. 1 consists essentially of the distribution box 2, the Ausasselement 3 and this downwardly closing outlet nozzle strip 4.
  • the air distributor usually forms together with a plurality of other similar air distributors, which are under the ceiling of the room to be ventilated are hung, the ventilation system.
  • Each air distributor which has a length of one or two meters, for example, but can also be produced in any other length without waste, the air to be distributed is supplied approximately in the middle of the distributor through a side air supply nozzle 5, which, as in the drawing can be seen, is attached to the corresponding inner wall of the distribution box, for example by gluing, with an outer flange and extends outwards through a corresponding hole in the wall of the distribution box.
  • a suitable air supply line can then be pushed onto the connecting piece 5.
  • the nozzle can also be attached at the top.
  • the air distributor 1 is composed of three components, namely a left side part 6, a right side part 7 and an outlet nozzle strip 4.
  • the two side parts 6 and 7 are up to the upper profile 8 for connecting the two side parts 6 and 7 are the same.
  • the upper profiling 8 is preferably of identical design on both side parts.
  • Each of the two side parts 6 and 7 consists of an extruded light metal profile, which, roughly speaking, has a rectangular flat U-profile, from one leg edge - in Fig. 1 the edge of the lower leg 10 - there is a web 11 parallel to that two legs of the U-profile connecting web 12 extends.
  • the outlet element is also remarkable in that it is quite narrow.
  • the width of this element can go down to about eight millimeters. This greatly facilitates the incorporation of air distributors according to the invention into coffered ceilings, panel ceilings and the like. Despite the small width, due to the design of the outlet nozzle strip 4 and the outlet holes to be discussed later, a perfect desired air distribution can be ensured.
  • the air distributor 1 is closed at both ends by inserted end plates, which are advantageously in the form of injection molded plastic parts or stamped sheet metal parts and which normally run parallel to the plane of the drawing in FIG. 1. However, several distributors 1 can also be aligned or at an angle - e.g. using appropriate transition pieces - connect to each other.
  • T-grooves are provided in corresponding projections.
  • Web parts 16 or other corresponding elements can be inserted into these, for example, by means of which the air distributor 1 is suspended from the ceiling of the room, for example by means of threaded rods 17, which allow an exact adjustment of the height of the air distributor.
  • the corresponding T-profile grooves 15 located at the bottom in FIG. 1 further components can be fastened, which can serve, for example, to support a cassette ceiling located underneath.
  • similar T-profile grooves 18 are arranged in the corners between the webs forming the side walls 11 of the air outlet element 3 and the corresponding legs 10 of the U-profile.
  • the latter are first bent 45 ° inwards and then 90 ° outwards.
  • Correspondingly complementary beads or edge beads 20 of the outlet nozzle strips 4 engage in the sharp-edged beads thus formed on the free edges of the webs 11.
  • FIG. 24 shows a larger scale.
  • the outlet nozzle strip 4 has the profile of a roof opening downwards at an angle of 90 °, from the free edges of which ribs 21 project vertically upwards.
  • connection profile 8 the two side parts, which are connected above by the connection profile 8, are also clamped together below.
  • a certain preload is ensured in that the two side parts 6 and 7 are supported on one another at the transition into the outlet element via the perforated plate 14.
  • outlet holes 23, 24 In the longitudinal direction of the outlet nozzle strip 4, that is to say in FIG. 24 perpendicular to the plane of the drawing, near the roof edge in the two sloping roof surfaces on the right and left, there are alternating outlet holes 23, 24.
  • the structure and arrangement of these holes is explained in more detail below with reference to FIGS. 29 to 32.
  • the edge part of the web 11 which is angled inward at 45 ° and which is the bead for the receptacle of the edge bead 20, runs perpendicular to the outflow direction of the air from the adjacent outlet hole 23 or 24 and extends to the corresponding roof wall part.
  • this part of the corrugation also forms an air duct, which reduces the outlet pressure loss and thus also the sound generation, and gives the emerging supply air jet great directional stability.
  • the second lower part of the edge bead in FIG. 24 lies against the corresponding roof part of the outlet nozzle strip, so that a perfect connection is ensured.
  • the play between the different parts is not as great in practice as shown in FIGS. 1 and 24.
  • the game is only large enough to allow the parts to be pushed into one another or possibly snapped into one another.
  • FIGS. 29 to 32 Advantageous options for making the air outlet holes in the nozzle bar 4 are shown in FIGS. 29 to 32.
  • a sectional view similar to FIG. 24 is shown at the top, and the top view of the sectional view is shown below.
  • the outlet nozzle strip can also be designed differently than shown in FIG. 24.
  • the lower end wall of the outlet element is formed by a flat part 30 of the outlet nozzle strip 31, which also engages in this embodiment with hooked edge beads in correspondingly shaped edge beads of the webs 11.
  • the lower part of the bead lies on the horizontal base part of the outlet nozzle duct, which has a substantially U-profile at 31.
  • the upper parts 33 of the beads, which run flat in their lower area, are directed obliquely downward at 45 °, and in fact extend the holes 34 for the air outlet.
  • This construction is also suitable for air outlet channels 34 which are inclined alternately at an angle of 45 ° to the right and left to the side, but which have to be drilled or milled, which is not necessary in the case of an outlet hole arrangement according to FIG. 24.
  • the outlet nozzle strip 36 which also has a U-profile, but carries the horizontal foot 37 at a considerable distance from the edge beads of the webs 11.
  • the horizontal foot 37 is penetrated in the middle by punched air outlet holes 38.
  • extensions of the side legs of the U-profile serve to hold the emerging air jet together more sharply and to deflect it in the desired blow-out direction.
  • FIG. 25 A further outlet nozzle strip 40, which also fits on a web formation according to FIG. 1, is shown in FIG. 25.
  • the holes 42, 43 are expediently drilled. They each run at 45 ° to the vertical.
  • the upper wall of the outlet nozzle strip 40 is shaped such that it each has a wall of the normally, as shown in FIG. 29 to 32 can be seen, slot-shaped outlet holes 42, 43 are extended, namely in the extension of the bead inner wall at the edge of the corresponding web 11, so that excellent air flow is also ensured here.
  • Fig. 28 shows a further variant of a 1 A uslöndüsenance 45, which is also provided with an edge bead formation of the webs 11 according to FIG. Is usable.
  • the roof profile of the outlet nozzle strip 45 opens upwards.
  • beads 46 are provided on the edge, which engage in the edge beads of the webs 11.
  • the air outlet holes are provided alternately side by side in one and the other roof surface in the longitudinal direction of the bar.
  • tension bolts for example, can clamp the two webs 11 together at appropriate intervals.
  • the particular advantages of this construction lie in the fact that z. 32 minimum air outlet widths of less than 10 mm can be realized.
  • This connection can be designed according to FIG. 1.
  • the profile must be chosen so that the interlocking parts can not slide apart.
  • connection profiling 8 Another embodiment for the connection profiling 8 is shown in FIG. 2.
  • edge profiles of the side parts 6 and 7 engage in a meandering manner.
  • Such a profile can only be pushed into one another, while the profile according to FIG. 1 with a clever design does not allow pulling apart by movement in the plane of the drawing, but does allow it to pivot apart.

  • a connecting strip 63 is provided for connection, which is advantageously also extruded and whose profile can be seen in FIG. 6.
  • Such a design has the advantage that the front projections 64 of the connecting strip 63 first engage behind the ribs 62, but can be pulled out again in this position because of the corresponding profiling of the projections 64. Only when the side parts 6 and 7 are pushed together as far as they will go do the second projections 65 of the connection engage 63 behind the ribs 62 designed as barbs.
  • connection can now only be released by axially pushing apart perpendicular to the plane of the drawing, but no longer by moving the connected parts in the plane of the drawing.
  • the latter can only be achieved if the connection profiles are made very thin-walled, so that a tilting apart is caused by strong elastic deformations.

So that the position of the glass wool strip is clearly fixed, the two webs 11, which essentially form the air distribution element 3, are extended into the interior of the box by ribs 71. The length of the ribs corresponds to the thickness of the insulating layer 70.

If you want to avoid a wobble fit, a suitably narrow dimension is recommended, for example in that the leg 76 is slightly bent to the left before the rib profile 71 is inserted. With a correspondingly large dimensioning of the notches and the complementary depressions, it is only possible to insert them perpendicular to the plane of the drawing.
