Definitions
- the invention relates to an inductive air passage at intervals over its Exhaust ports arranged in length. Through these, individual rays are one Supply air flow can be conducted alternately in divergent directions.
- the air outlet consists of a housing which is U-shaped in cross section with two longitudinal halves arranged inclined to each other by a V-shape formed bottom part and one used in the housing, the air flow in the individual air jets dividing and deflecting device.
- the known air passage requires Core pieces of different lengths. Made up of several strings An air passage can only be assembled from core pieces of the same length if the sum of the partial lengths of the individual core pieces with the longitudinal extent of the passage matches. Due to the already relatively complex to produce core pieces, the known air outlet is expensive.
- the invention has for its object an inductive air passage to propose the type described above, which is particularly efficient few correspondingly designed components in different lengths put together and also in a fire-resistant version can be produced and permanently provided with an individual color application can be.
- the inventive design of the air passage not only makes it possible the housing, but also that used to split the supply air flow into individual air jets and for their deflection necessary equipment made of sheet metal manufacture.
- the devices to be inserted into the housing consist of a number of relatively short, depending on the viewing direction in cross-section Z or S-shaped sections that are completely identical in a particularly advantageous manner trained and only alternate to mirror each other to be arranged in succession until the casing is completely along with its sections over its length is equipped. In this way, their length can be very different Equip air vents with facilities that only differ from one large number of identical sections can be assembled.
- each section of the facility extends across the width of the housing, it is provided with an opening, through which the supply air flow the housing perpendicular to its longitudinal extent can flow through with a single jet per section.
- a lower Z leg or S-arm extends over only part of the width of the Housing, so that there is no flow obstacle for the single jet. Instead, the lower Z-leg or S-arm forms with it opposite section of each one longitudinal half of the bottom part one Lead channel. This is obliquely aligned and consequently one in the longitudinal direction of the housing adjacent, also diagonally aligned guide channel diverging The guide channel opens into one outlet opening, which opens into the other Longitudinal half of the bottom part is provided.
- the V-shaped to each other Bottom parts of the housing are each with a row of outlet openings provided, of which in one longitudinal half of the bottom part to those in the other longitudinal half of the bottom part are arranged offset to each other.
- each section with edge strips upper Z-leg or S-bow under spring elastic preload between pinched the longitudinal side walls of the housing.
- the sections made from sheet metal pieces are preferably punched or Pressing process so shaped that each section is in its between the long side walls of the housing pinched position with an edge of the lower Z-leg or S-arm against elastic pre-tension a longitudinal side wall of the housing is pressed.
- This configuration allows each section used in the housing position stable.
- the passage consists of an elongated, U-shaped in cross section Housing 1, in which a device extending over its length is arranged is to inject a supply air flow introduced via the open top of the housing Subdivide individual beams and divert them in divergent directions.
- the housing 1 is provided with a bottom part 2, which consists of two V-shaped longitudinal halves 3 and 4 arranged inclined to one another. Like Fig. 2 clarifies, are in the longitudinal halves 3 and 4, three outlet openings 5 and 6 provided at even intervals over the outlet length, wherein each outlet opening 5 in the longitudinal half 3 to each outlet opening 6 in the Longitudinal half 4 is arranged offset.
- the device dividing the supply air flow into individual jets and deflecting it exists in accordance with the number of outlet openings 5 and 6 from a total of six relatively short sections 7, which in cross section Z or Are S-shaped.
- Each section 7 has an upper leg or Arch 8, which extends over the full width of the housing 1 and with an opening 9 is provided. Furthermore, each section 7 has one lower leg or bow 10, which is about half the width of the housing 1 extends.
- An individual air jet passing through the opening 9 is passed through the section 7 deflected and fed to a guide channel 11, which on the one hand by a Longitudinal half 3 or 4 of the bottom part 2 and on the other hand through the leg or sheet 10 is limited.
- the guide channel 11 thus defined closes with its Exit cross section at an outlet opening 5 and 6 respectively.
- the inductive individual supply air jets come in from the outlet openings 5 and 6 divergent directions inclined into the room to be supplied with supply air a.

Claims (4)
- Induktiver Luftdurchlaß mit in Abständen über seine Länge angeordneten Auslaßöffnungen (5, 6), durch welche Einzelluftstrahlen eines Zuluftstromes nacheinander abwechselnd in divergierende Richtungen leitbar sind, bestehend aus einem im Querschnitt U-förmigen Gehäuse (1) mit einem durch zwei V-förmig geneigt zueinander angeordnete Längshälften (3, 4) gebildeten Bodenteil (2) und einer in dem Gehäuse (1) eingesetzten, den Zuluftstrom in die Einzelluftstrahlen unterteilende und umlenkende Einrichtung, dadurch gekennzeichnet, daß die Einrichtung aus einer Vielzahl Z- bzw. S-förmiger, identisch ausgebildeter Abschnitte (7) zusammengesetzt ist, die abwechselnd spiegelbildlich aufeinanderfolgend angeordnet sind, wobei ein jeweils oberer Z-Schenkel bzw. S-Bogen (8) sich über die Breite des Gehäuses (1) erstreckt und mit einem Durchbruch (9) versehen ist, während ein jeweils unterer Z-Schenkel bzw. S-Bogen (10) sich über nur einen Teil der Breite des Gehäuses (1) erstreckt und mit dem gegenüberliegenden Teilstück der jeweils einen Längshälfte (3) des Bodenteils (2) einen Leitkanal (11) bildet, dessen Austrittsquerschnitt an einer in der jeweils anderen Längshälfte (4) des Bodenteils (2) vorgesehenen Auslaßöffnung (6) angeschlossen ist.
- Luftdurchlaß nach Anspruch 1, dadurch gekennzeichnet, daß jeder Abschnitt (7) mit Randstreifen des oberen Z-Schenkels bzw. S-Bogens (8) unter federelastischer Vorspannung zwischen den Längsseitenwänden des Gehäuses (1) eingeklemmt ist.
- Luftdurchlaß nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß jeder Abschnitt (7) in seiner zwischen den Längsseitenwänden des Gehäuses (1) eingeklemmten Position mit einer Randkante des unteren Z-Schenkels bzw. S-Bogens (10) unter federelastischer Vorspannung gegen eine Längsseitenwand des Gehäuses (1) angepreßt ist.
- Luftdurchlaß nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß der Abstand zwischen zwei in einer Längshälfte (3, 4) des Bodens (2) aufeinanderfolgenden Auslaßöffnungen (5, 6) größer ist als die Länge einer jeden Auslaßöffnung (5, 6).
