Definitions

  • the invention relates to a device for supplying or discharging air via an air duct system which is connected via a transition piece to a distribution box to which a ceiling outlet or inlet connects.
  • Distribution boxes in various designs are available for supply air outlets, especially ceiling outlets. These distribution boxes can have a round, square or square shape. Large amounts of air have to be transported to these distribution boxes, so that the corresponding connections to the air duct system are also very high. In many cases, for example, a false ceiling does not offer enough space to accommodate such a high distribution box with the corresponding connections to the air duct system. In these cases, two or more connections are now installed instead of a transition connector, the installation of which is complex and expensive.
  • distribution boxes today consist of a simple, generally rectangular housing and have on the one hand an inlet opening to an air duct system and on the other hand an opening which is covered by any ceiling outlet. This means that this distribution box only fulfills its function of distributing the air volumes very inadequately.
  • the present invention has for its object to provide a device of the above. To develop a way by which a large amount of air can be introduced into a distribution box, but this distribution box is kept as deep as possible. Furthermore, the distribution function of the distribution box is to be significantly improved.
  • the transition nozzle has a nozzle for connection to the air duct system and an approximately rectangular mouthpiece for connection to the distribution box.
  • connection to the air duct system has the same diameter as before, so that the corresponding air duct noises remain low.
  • the outlet opening to the distribution box also has the same area, but only half the height, so that the corresponding distribution boxes can also be kept considerably lower in height. These lower distribution boxes can then be inserted into the corresponding false ceilings without difficulty and do not protrude from them.
  • the connector as a connection to the air duct system is an approximately cylindrical tube section, after which the housing is then squeezed in the area of an intermediate piece from one or two sides, so that a funnel-shaped intermediate piece is created. At this funnel-shaped intermediate piece then connects the above-mentioned rectangular mouthpiece.
  • the corresponding outlet opening in the mouthpiece runs around an annular flange, via which the entire transition piece can be fixed to a distribution box.
  • the great advantage of the invention is that relatively low boxes can be charged with large amounts of air. So far, the boxes had a height of about 500 mm, the height now required is only 300 mm. This is of great importance for assembly, transport and, above all, installation. Especially on construction sites, space is to be saved everywhere today, which is possible with the box according to the invention with the connecting piece.
  • the distribution box should have an inlet opening to which a movable quantity adjustment plate is assigned.
  • the outlet opening is bounded by a connection frame for the transition piece.
  • this connection frame is pulled out of a connection side of the distribution box, a corresponding tool being necessary. It does not matter whether the inlet opening is oval or rectangular. In any case, a further operation to produce this connection piece is avoided.
  • the quantity adjustment plate preferably consists of a perforated plate and is shaped accordingly so that it has its own stability.
  • the quantity adjustment plate can be moved in the desired way in front of the inlet opening, so that a uniform distribution of the supply air within the Box can take place. As a result, the exposure is equalized so that noise is avoided.
  • the quantity adjustment plate is connected to a spindle at least via a spindle sleeve.
  • This spindle is located within the distribution box and extends from the cover to a bearing bracket in the preferred embodiment.
  • the spindle is rotatable so that the quantity adjustment plate can be adjusted in front of the outlet opening from below using a screwdriver. All adjustment elements are corrosion-proof and designed in such a way that they do not develop any intrinsic noises caused by rattling, etc.
  • a pressure compensation plate follows the quantity setting plate in the distribution box.
  • a corresponding perforated plate or other swirl plate is also used for this and is shaped and fixed in such a way that it has sufficient inherent stability.
  • the fixing can be done with appropriate fasteners.
  • these are screw anchors that have an axial slot in which the perforated plate is inserted.
  • the present distribution box should be suitable for screw mounting and also for concealed mounting of a ceiling outlet.
  • the ceiling outlet is simply screwed onto the housing of the distribution box.
  • a crossbar is provided for concealed mounting, which consists of a beam on which two flat hooks are molded on the side. These flat hooks are inserted into slots in the side walls so that they are covered by a holding strip in the position of use.
  • the entire distribution box consists of only a few individual parts.
  • One is a U-shaped side wall frame, the two free side walls being connected via the connection side.
  • the connection is made by cribs.
  • a cover is placed on the distribution box opposite the ceiling outlet, which is also connected to the side wall frame and the connection side by cribs.
  • a connecting piece is also pushed on from the side wall frame and the side strips or front strips projecting from the connection side.
  • This nozzle plate can also be removed and replaced by another nozzle plate, for example with a round outlet.
  • the round outlet is then particularly suitable for round ceiling outlets.
  • the distribution box can have any shape, for example square, rectangular, round, roman or oval.
  • the box is made of zinc sheet, but other materials such as aluminum, brass, etc. are also conceivable.
  • An inventive transition piece R has gem.
  • Feg. 1 a housing 1, which on the one hand forms an inlet opening 2 and on the other hand an outlet opening 3 for air.
  • the inlet opening 2 is encompassed by a cylindrical connecting piece 4, which connects to an air guidance system, not shown in detail.
  • the cylindrical socket 4 merges into a funnel-shaped intermediate piece 5, to which a rectangular mouthpiece 6 then connects.
  • the intermediate piece 5 is produced by squeezing the cylindrical connecting piece 4 on both sides, the corresponding crease line being identified by 7.
  • the outlet opening 3 is encircled by an annular flange 8, a corresponding connecting piece 9 to a distribution box, not shown in detail, being shown in broken lines.
  • FIGS. 5, 6 and 8 show a further exemplary embodiment of a transition piece R1.
  • this transition piece R1 an intermediate piece 5a is not formed squeezed on both sides.
  • An upper side 10 of the intermediate piece 5a is flat, while a partially conical jacket section 11 extends from the connection piece 4 to the mouthpiece 6.
  • the transition piece R and R1 is used to connect an air duct system (not shown in more detail) to a distribution box P shown in FIGS. 5-12.
  • This has a U-shaped side wall frame 12 which forms two side walls 13 and 14 and a rear wall 15 .
  • the side walls 13 and 14 are connected to one another via a connection side 16, the connection side 16 with side strips 17 and 18 on both sides engaging over the side walls 13 and 14.
  • the connection side 16 is connected to the side wall frame 12 by cribs.
  • a cover 19 is placed on the side wall frame 12 and the connection side 16. This cover 19 also overlaps the side wall frame 12 or the connecting side 16 with corresponding strips and is connected to these parts by cribs.
  • side strips 20 and 21 and a rear wall strip 22 are folded from the side wall frame 12, which are connected to one another and to a front strip 23 bent from the connection side 16 via corner brackets 24.
  • a spigot plate 25 is pushed onto these strips 20 to 23, with corresponding guide strips 26a, 26b and 26c engaging over the side strips 20 and 21 and the front strip 23.
  • the nozzle plate 25 which is rectangular in the present exemplary embodiment, by a nozzle plate, for example with a round outlet for a round ceiling outlet (not shown in more detail).
  • the connecting plate allows the attachment of an adapter piece if, for example, there is a distance to be bridged between a false ceiling and the distribution box.
  • a cross member 26 is provided in the distribution box P between the side walls 13 and 14 to fix a ceiling outlet (not shown in more detail).
  • a holding strip 29 is punched out of the side wall 13 and 14 through two parallel slots 27 and 28, which in the position of use overlaps a flat hook 30, which the cross member 26 is molded on. This cross member 26 thus holds without any welded connection.
  • a sleeve 31 preferably made of plastic, which has a thread (not shown in more detail) for a spindle 32, which is only indicated by dashed lines.
  • a ceiling outlet grille on the nozzle plate 25 of the distribution box P can be determined. This results in a concealed mounting of the ceiling outlet grille, but it is also within the scope of the invention that the ceiling outlet grille is connected to the nozzle plate 25 via a normal screw mounting. In this case, the cross member 26 is unnecessary.
  • the traverse 26 still has the advantage that it can consist of half pieces and is therefore manufactured with a tool for all sizes. It is only inserted into the sleeve 31 in the middle.
  • the transition piece R1 sits on the connection piece 9 of the connection side 16 and covers there a rectangular inlet opening 33, which is better shown in FIG. 7.
  • a connection frame 34 is used to hold it However, it can also consist of different strips 34a (see FIG. 10).
  • a special tool is used to pull out a lead frame 34a even with an elliptical inlet opening 33a, as shown in FIGS. 11 and 12.
  • a quantity adjustment plate 35 is assigned to the inlet opening 33, which is a rectangular perforated plate in the present exemplary embodiment.
  • This quantity setting plate 35 is connected to a spindle sleeve 36 which is penetrated by a spindle 37 which is mounted in the cover 19 and at an angle 38.
  • Another spindle sleeve 39 gives this quantity adjustment plate 35 a desired stability.
  • the spindle 37 can be attacked and rotated from below with a screwdriver, so that the spindle sleeves 36 and 39 are adjustable in the direction of the double arrow x and set the quantity adjustment plate 35 in front of the inlet opening 33 to a desired extent.
  • a pressure compensation plate 40 within the distribution box P, which is also made of a perforated plate or another swirl plate and is molded accordingly, so that it has a certain intrinsic stability.
  • This pressure compensation plate 40 is fixed to the side walls 13 and 14 by means of commercially available clips or slotted fastening elements 41.
