A part of a fiberglass duct is used for the air supply. Fiberglass is a commonly used material from which such guide ducts are formed, as it can easily be brought into any shape adapted to the respective installation conditions. The simplest such shape represents a channel of approximately triangular cross-section, which is formed by two folds 45 (FIG. 3). Such a triangular channel consists of an upper part and two side parts 47 and 48. The lower parts 47a and 48a of the two Side parts are inserted into the guideways which are formed by the arms 29 and 30 of the base bodies 21 and 22, which are arranged at a distance from one another. To facilitate this operation, the upper ends of the arms are curved 29 to the outside (29a) ₀ The upper part of the arm 30 has an inwardly directed thickening 30a formed by a shoulder 30b, "A generally designated with 49 Brackets for the air supply are attached to both sides before the air supply is inserted. This holder consists of an adapted length of a sheet metal strip with a flange 50 at its lower end, a side part 51 of an outwardly projecting fold 52, one after

inwardly directed projection 53 and a release lever 54 at the upper outer end. The brackets 49 are applied to the edges of the air duct »with the projections 53 securing the fastening in the Engage fiberglass material. The air duct with the brackets is then placed between the arms 29 and 30 inserted, creating da3 elastic fiberglass material is pressed together slightly and the outwardly directed fold 52 is in its position below the shoulder 30b snaps into place so that the air duct is securely held on de & G round bodies 21 and 22 and the connection as such is designed to be self-sealing against an air passage. Becomes the trigger 54 pressed inwards, the fold 52 is released from the shoulder 30b, and the air duct can be removed from the duct.

Limiting members generally designated 55 are placed on the inner flanges 24 and allow the air flow to be adjusted. These Limiting members are formed from a full length of sheet metal to form a "U", the legs of which are one Form top 56 and a bottom 57. These lower and upper parts lie against the inner flanges 24 firmly on friction. The inner flanges can also be formed with recesses 24a, in which the bent end 56a can engage in a number of positions. The end 57a is bent outwards and in this way forms a handle that easily removes the limiting member from the under the ceiling can be adjusted.

Between the base bodies 21 and 22 there is a deflecting part, generally designated 58 (Fig. 8, 9). It "consists of a plate 59, the longitudinal edges of which are bent over to form puddles 60. In the middle part a multitude of triple cuts is made, with the cut-out metal surfaces facing downwards are bent and thus form a row of baffles 61 and openings 62. This deflection part causes that the linear air flow supplied to the air duct is undirected downwards.

Along the lower side is an air distributor, generally designated 64, as a terminating element provided, which is also preferably made of drawn metal. This part has a reset Middle part 65 into which the upper edge of a partition can be inserted, if the su ventilating seam is subdivided «, A flow divider 66 runs along the I-Iitcellinie of the terminating part c upwards and has an arrow-shaped edge 67 at its upper end. To each A plurality of through openings 68 are provided on the side of the flow divider 66. Farther are on each side upwardly extending support flanges 69 with a shoulder 70 on their inside intended. These shoulders 70 engage in the angled ends 32 of the support members 51 and hold the end part in the desired position.

In practice, the longitudinal beams 15 are usually spaced about 1.2 m apart arranged. The basic bodies are accordingly

MD «*» «'109835/1067

21 and 22, the deflecting part 58, the cover parts 46 "to 48, the holders 49 and the limiting members 55 are cut to this length and supplied (or in a length which is shortened by the amount that corresponds to the thickness of the details of the embossing device). The end pieces that form the air distributor are also delivered in precisely this lung

Of course, all individual parts for such a unit can be used together, individually or together, packed and delivered to the workplace in this form, but it is more economical to pack and transport the individual parts separately. The units are then on the job in question, but it is not necessary to include this job in Ceiling height before increasing <, Rather, this assembly can be easier and faster on the floor or a Yferkbank. Advantageous it is proven that the fiberglass material is used for the air duct (for folding) already notched, and the brackets 49 are on each long side attached, and then the rails with the side arms pushed over it. The air distribution duct is then formed by the fact that the side surfaces are unfolded until the G-round body are opposite to each other and the fastening members 35 are inserted into them, so that the base bodies are spatially arranged at the correct distance from one another. Insertion of the side members of the fastening members in the

109835/1067 ORIGINAL BATHROOM

corresponding guide trough η is through the larger length and the curved cut of the end of the side member 38 facilitated. The limiting members are located from the outset on the paddles that support them 24ο The split-up air distribution duct is then turned over / and the diverter 58 can be attached if it is to be used.

The finished assembly unit can then can then be attached to the ceiling structure. Since it is quite light in weight, it can be done in a simple manner by a single worker be raised and brought into the desired position in which they the gap spanned between two girders. It is hung on the T-beams and can, starting from one End by pressing the bracket of the upper part of the fastenings 35 securely at the open end of the T-beams are attached. Another unit can then be assembled in the manner described and installed. If the plan provides, two or more lengths of one to arrange such air distributor in sieve, can the next unit is installed in a similar manner and lengthways to the previous one will. A precise alignment is thereby automatically achieved in that the gripping claws 40, 41 and 42 each of two associated fastening members interlock. Usually it is used to avoid it of leaks provided that the adjacent ends of the units with a sealing material be provided.

109835/1067

The air distribution ducts are supplied with a longitudinal (in technical language called "linear") air flow, the Enters through the fiberglass guide at one end is connected to a supply line. In this case, deflection parts are usually installed, which the air flow downwards direct, but the air can also be supplied to the units through an attached knee joint 73. The Ends of the air duct are closed with cover members 74, which are also expediently cut from fiberglass material and are attached under sealing.

After all units are arranged in a row in the desired manner the end piece 64 cut to suitable lengths can be attached. Does the air distribution duct run in a room from one wall to the other, the end part 64 will have exactly this length. Because that Closing part 64 is pushed upwards, the Iragglieder are with their shoulder 70 in engagement with the shoulders 32 on the Straps 31 forced. As can be seen from FIG. 1, the terminating part 64 is located below the lower edge of the flanges 18 the T-Trägey, so that in this way the appearance of a finished ceiling is achieved. In the event that the air distributor 64 only extends over part of the space, filler pieces (not shown) can be inserted into the open end portions that are located below the lower edge of the base body 21 and 22 and above the air distributor 64 are used.

109835/1067

As already stated, the air manifolds 64 can be of the same length as the others Parts of the device are delivered, in which case they are no longer cut to size at the work site Need to become. However, a continuous length makes this end part a better one Look, because most or all of the bumpy links be avoided between their ends »when SoBo arranges the air distribution units this way are that they meet at right angles on the ceiling, can do the appropriate parts of the device including the air manifold so surecht. be cut so that they are mitred bump into each other "

After installing the device, the limiting elements become adjusted to the desired air flow rate on each side of the air manifold 64. Included the setting is done independently on both sides from each other because the gap between the flow divider 67 and the restriction member 55 can be set individually on each side. In this case, a delimiting element can optionally be brought forward so far that it hits the flow divider and so the air distribution duct on this Page closes completely.

The air distribution device according to FIG. 2 is identical to the device already described However, FIG. 2 shows a different embodiment in that it is a Arrangement is in connection with a ceiling, in which the ceiling panels 76 are not on the outside

- 20 109835/1067

lying flanges 77 of the T-beams rest, but are provided with slots 7ö, into which the flanges 77 run. With this arrangement of the ceiling panels, these lie against the flanges 25 of the air distribution ducts with a recess so that they remain arranged horizontally. The splash and 77 are at the same level, both in the case of the ceiling arrangement according to FIG. 1, as well as in an arrangement according to FIG. 2, but in the latter case the support structure is covered,

Figures 11 to 15 show a modified embodiment of the invention. Here are the basic bodies 83 and 84 compared to the Örundi bodies 21 and 22 modified as follows; the inner flanges designated here by 85 are arranged higher than the inner flanges 24 and the support members 31 for the air manifolds 64 are omitted. Instead of the apertured air manifold 64 is an in-line flow divider 86 provided, which consists of a base plate 86a with a flow divider 87 directed upwards triangular head 88 is made. On each side of the flow divider 87 are outwardly directed Flanges 89 attached at a distance from and parallel to the bottom plate 86a. Here too " The air diffuser is made of drawn material that is trimmed to such a length is that it is between the flanges 18 of adjacent T-beams 15 in the ceiling>: onstruktion extends.

109835/1067

The air distributor is supported on a mounting member in the air distribution device. These fasteners v / iron a pair of horizontally extending clip pieces 92 attached to opposite Sides of the flow divider 87 into the space between the puddles 89 and the bottom plate 86a are fitted. One located between the brackets Slot 93 encompasses the flow divider, for G reasons that will be discussed further in the description result, the slots are formed so that they extend to the inner surface of the rear face 95 of the Fastening member run. As handles for attaching and detaching to the ceiling structure handles 94 bent upwards are provided.

How best to get out of the Pig. 15 results, the fastening members 91 are the paddles 18 of the T-beams 15 when the device is attached to the ceiling structure. The top of the Back front 95 of the fastening members lie the undersides of the paddles 85 in the fully assembled and built-in device so that the air manifold 86 against upward movement is secured. Palis the limiting members 55 run over the entire length, they are provided with a recess on their band part, e.g. at 56b, so that there is enough space for the fastening links 91. The fastening links lie between the side members 37 and 38 of the fastening members 35 the porters. The rear face 95 of the fastening members 91 has the same length as the inside distance between the rails 23 of the base body 83 and 84, so that the

- 22 1098 35/1067

Flow divider 86 is centered between the two main bodies. This way you get to both On the sides of the base plate 86a, the same air passage slots 83 'through which the ventilation air pass can. The air flow through each of these slots can be in the manner already described can be adjusted by adjusting the limiter members 55. In this embodiment of the Invention one obtains a flush arrangement of the air distribution device, which is necessary for its installation in a DecL-center construction is particularly attractive.

While in the previously described embodiment 3form of the invention of the air distributor 64 from the air duct system is carried, the air distributor 86 and also the Air distribution duct system of the Deeken construction on, which in this way a shift of the air distributor downwards or in the longitudinal direction prevented. Since at the same time the fastening members 91 of the air distributor with the air distribution duct arrangement connected, there is also a «? upward or sideways movement of the built-in air distributor. Because of these connections and because it is desirable is to arrange the air distributor in a detachable manner, when attaching the device according to FIG. 11 special operations are required in connection with the special fasteners. After the duct unit is assembled and attached to the ceiling structure has been, the fastening member 91 is as far as it goes into the respective end of an air distributor
