Fig. 5-8 show schematically different possibilities to others it. flowing direction of the air by assembling, of the cells in different ways and Figs. 9 and 10 show another salt • to assemble the cells, whereby the air is given a rotating motion. The grid Or shown in Figs. 1 and 2 composed of eight is fitted with equal cells 1, consisting of a frame 2 and slats 3 inserted therein. The cells 1 are fitted into an insert frame 4, to which Or is attached an angle iron 5, which by means of screws 6 is screwed either directly to the yag surrounding the tail intended for mounting the grid in the room in question, or, as in the embodiment shown, to a flat socket 7 inserted in the hole in the cradle. Or denoted by 8.

Insatsramen 4 har Ai:Sue djup On cellerna 1 och i forlangningen av skiljeytorna mellan de ph varandra anbragta cellerna 1 Oro anordnade vertikala styrplatar 9, vilkas framre, i vinkel bOjda kant 10 bildar anslag och bakre stod for cellerna. Vid insatsramens 4 baksida Oro ph axlar 11, som Oro fasta i ramen 4, vrid bart lagrade spjall 12, vilka installas i beroende av riktningen hos den utblasningstrumma, genom vilken luften tillfores. Cellerna 1 hallas pa sin plats av en ytterram 13, som Or medelst skruvar 14 fast vid vinkeljarnet 5. Lister 15 tacka framkanterna av skiljeytorna mellan de olika cellerna och genom att dessa lister 15 bukta nagot Mat astadkommes en anpressning av ytterramen 13 mot cellerna, varigenom dessa komma att sitta mycket sakert och stabilt fast i innerramen. Denna stabila fastsittning befordras ytterligare, om eellernas lamellerna omgivande ram Oven uthildas med na.got utbuktade sidor. The insert frame 4 has Ai: Sue depth On the cells 1 and in the extension of the dividing surfaces between the ph arranged one another 1 Oro arranged vertical guide plates 9, the front, angled edge 10 of which forms abutments and the rear stood for the cells. At the rear of the insert frame 4, the shafts 11, which are fixed in the frame 4, rotate bare bearings 12, which are installed depending on the direction of the blow-out drum through which the air is supplied. The cells 1 are held in place by an outer frame 13, which Or is fastened to the angle iron 5 by means of screws 14. these will be very securely and stably attached to the inner frame. This stable attachment is further promoted, if the ornaments of the slats surrounding the oven are supported with slightly bulged sides.

Cellernas uppbyggnad framghr av fig. 3 och 4. Lamellerna 3 bcstar av platar, som hava en med ramens 2 sidor parallell del 16, vilken efter en mjuk homing overgar i en andra del 17, som bildar vinkel med den fOrra delen 16. Lamellerna Oro yid sidorna av delen 16 forsedda med flansar 18. Nb.' gon sarskild fastsattning av lamellerna erfordras icke, utan de fastballas i sitt lage enbart genom flansarnas 18 fjadrande anliggning mot ramen och mot intilliggande lamell. Cellerna kunna insattas antingen med den sida valid utat, vid vilken lamellernas med ramen 2 parallella del 16 Or belagen, i vilket fall luften bibringas en stromningsriktning rakt ut, eller med den sida valid utht, vid vilken den ,snett riktade delen 17 Or belagen, i vilket fall luften bibringas en stromningsriktning at ena eller andra sidan eller uppat eller nedat beroende ph i vilket lage cellen 1 insattes i ramen 4. The structure of the cells is shown in Figs. 3 and 4. The slats 3 consist of plates which have a part 16 parallel to the sides of the frame, which after a soft homing merges into a second part 17, which forms an angle with the front part 16. The slats yid the sides of the part 16 provided with flanges 18. Nb. ' no special fastening of the slats is required, but they are fastened in their position only by the resilient abutment of the flanges 18 against the frame and against adjacent slats. The cells can be inserted either with the side valid out, at which the slats 2 parallel to the frame 2 Or coated, in which case the air is imparted a flow direction straight out, or with the side valid utht, at which the, obliquely directed part 17 Or coated, in which case the air is imparted a direction of flow on one side or the other or up or down depending on the pH in which the low cell 1 was inserted in the frame 4.

I fig. 5-8 visas exempel ph nagra olika mojligheter att rikta den utblasande luftstrommen vid galler av det i fig. 1 och 2 visade utforandet. Harvid Or forutsatt, att de hada ovanpa varandra anbragta cellerna bla.- sa luften i samma riktning. I fig. 5 rikta samtliga celler luften rakt framat, vilket astadkonamits genom att insatserna anbragts med den i fig. 4 uppa't vanda sidan riktad utal. Enligt fig. 6 hava samtliga celler anbragts 2— — med den andra sidan utat och vridna ph samma Ott, sâ att hela luftstrommen riktas at ena sidan. Detta utforande anvandes exem.- pelvis, om utblasningsgallret maste anordnas nara en sidovagg. Vid utforandet enligt fig. 7 Masa de vanstra cellerna luften at vans-ter, de fyra mittre cellerna luften rakt fram och de hogra cellerna luften tt hoger. Pd detta satt astadkommes en spridning av luften. Harigenom erhalles variation av luftstrommens kastlangd. Enligt fig. 8 blasa de yttre cellerna luften at motsatt hall mot fig. 7, varfor i detta fall erhalles en koncentralion av luften. Det är latt att inse, att luftf5rdelningen sMedes kan anpassas efter praktiskt taget alla forhallanden endast genom cellernas olika placering i gallret. Fig. 9 och visa en och samma placering av cellerna, likaledes i ett galler med atta celler, i fig. endast mera detaljerat an i fig. 9. Genom denna placering av cellerna erhalles en roterande utblasning av luften, som skulle kunna tankas vara onskvard for att man skall erhalla en kraftig omvirvling av luften. Sasom utan vidare framgar av dessa figurer, blaser den langst till vanster anbragta cellen i ovre raden luften neat, medan de tre ovriga cellerna i samma rad blasa luften at vanster. I den nedre raden blasa de tre vanstra cellerna luften at hoger, medan den langst till ho-(ter anbragta cellen blaser luften uppat. Figs. 5-8 show examples of some different possibilities of directing the blowing air stream at grids of the embodiment shown in Figs. 1 and 2. Harvid Or assumed that they had placed the cells on top of each other, including the air in the same direction. In Fig. 5, all the cells direct the air straight ahead, which is achieved by placing the inserts with the number directed upwards in Fig. 4. According to Fig. 6, all the cells have been placed 2— - with the other side outwards and twisted ph the same Ott, so that the whole air stream is directed to one side. This design is used, for example, if the exhaust grille must be arranged near a side cradle. In the embodiment according to Fig. 7, the left cells mass the air to the left, the four middle cells the air straight ahead and the right cells the air slightly higher. In this way a diffusion of the air is achieved. As a result, variation of the throw length of the air stream is obtained. According to Fig. 8, the outer cells blow the air at the opposite hall to Fig. 7, for which case in this case a concentration of the air is obtained. It is easy to see that the air distribution can thus be adapted to virtually all conditions only by the different placement of the cells in the grid. Fig. 9 and show one and the same placement of the cells, also in a grid with eight cells, in Fig. Only in more detail than in Fig. 9. By this placement of the cells a rotating blow-out of the air is obtained, which could be thought to be unsightly. in order to obtain a strong vortex of the air. As can easily be seen from these figures, the cell furthest to the left in the upper row blows the air neatly, while the other three cells in the same row blow the air to the left. In the lower row, the three left-wing cells blow the air to the right, while the cell furthest to the ho-ter blows the air up.

Uppfinningen är givetvis joke begransad till de ovan beskrivna och p0. ritningen visade utforingsformerna, utan kan modifieras pa olika satt till sina detaljer med bibehMlande av det vasentliga for uppfinningen. AntalA celler i gallret ãr exempelvis fullt godtycldigt och enbart beroende pa den for genomslappande av onskad luftmangd erforderliga arean. Styrplatarna 9 kunna eventuellt vara anbragta horisontellt och spjallen 12 aro icke alltid erforderliga. Lamellerna 3 kunna hava annan lutning. Det kan ,exempelvis vara lampligt att hava tva eller tre standardutforanden pa cellerna, vilka endast skilja sig frau varandra genom lamellernas olika lutning. The invention is of course joke limited to those described above and p0. the drawing shows the embodiments, but can be modified in various ways to its details while maintaining the essentials of the invention. The number of cells in the grid, for example, is completely arbitrary and depends solely on the area required for the passage of the desired amount of air. The guide plates 9 may optionally be arranged horizontally and the slats 12 are not always required. The slats 3 may have a different slope. It may, for example, be appropriate to have two or three standard embodiments of the cells, which differ from each other only by the different inclination of the slats.
