Definitions

• the invention relates to an air outlet with air slides in an outlet plate, which can be fixed to a counter bearing via a traverse device.
• an outlet plate provided with air slots has been connected to a housing box and this to a corresponding air duct system.
• the connection is made either by screwing on the corner or by a central screw bolt, which meets a crossmember inside the housing. In any case, the screws are visible from the outside, which is not aesthetically desirable.
• the present invention has for its object to find an improved truss attachment for an air outlet, which reduces manufacturing and assembly costs.
• the traverse device is connected to the outlet plate at least via holding plates.
• These holding plates are attached or attached to the truss device at the end.
• As a holding plate there are above all the bearing plates already present in many air outlets, which accommodate air deflection slats between them. These bearing plates have recesses for receiving the axis of the air deflection plate, around which this air deflection plate rotates. These bearing plates can be punched out of the outlet plate and folded, placed on them or inserted into them (see utility model 87 00 243.4 or DE-OS 40 26 932.9).
• the holding plates which are matched to the respective truss device. If, for example, the traverse device consists of only one tube, opposing holding plates also have only one hole. This hole should preferably be oval and the cross section of the tube section should also be oval. This ensures that the crosshead device and outlet plate are secured against rotation.
• the truss device consists of two intersecting pipe sections. Both tube sections should preferably be oval in cross section.
• the holding plates have two oval holes arranged one above the other, the spacing of which corresponds to the distance between the intersecting tube sections.
• a second type of holding plate is provided, in which a slot in the form of a broken oval hole is provided. This enables this type of holding plate to be connected to a pipe section at a later time by inserting this pipe section into the slot. It is still possible to rotate this holding plate.
• the holding plates have a beveled T-web, through which grooves are formed for receiving edge edges of the air slot.
• Such configurations of holding plates as bearing plates for air deflection blades are described in German Utility Model 87 00 243. They ensure that the entire arrangement is easy to install, as will be described later.
• plug-in parts can be plastic plugs in which a head and an insert are formed. The head strikes the retaining plate from the outside, while the insert reaches through the oval hole and engages in the oval tube section.
• truss attachment has great advantages over all previous trusses. Above all, due to the special design of the truss beam, the best possible shape is chosen in terms of ventilation. There is no additional resistance or noise as the pipe sections have no edges. In particular, the production is very environmentally friendly. No point points are necessary anymore, so that corresponding point points do not have to be painted or sprayed with paints. There is a very high power requirement when dotting, and the coating is unnecessarily polluted by the wet coating. In addition, the corresponding work rooms must be ventilated, which causes additional costs. All this is omitted in the plug connection according to the invention. truss attachment and air outlet. In addition, the air outlet can be transported to the assembly site pre-assembled.
• Figure 1 is a plan view of an air outlet.
• Fig. 2 is a rotated -45 degrees, enlarged view of a portion of the air outlet acc. Fig. 1 in the direction of arrow II;
• Fig. 3 shows an enlarged and rotated by 45 ° cross section through a portion of the air outlet acc. 1 along line III - III;
• Fig. 4 is an enlarged and rotated -45 ° cross section through a portion of the air outlet acc. Fig. 1 along line IV - IV;
• 5 and 6 are a top view and a side view of a holding plate according to the invention.
• 7 and 8 are a plan view and a side view of a further holding plate according to the invention.
• an air outlet 1 is shown in plan view, which is generally known commercially under the term DQJ.
• This air outlet 1 has air slots 2 arranged in the manner of a dial in an outlet plate 3, which in the exemplary embodiment shown can have different lengths.
• Air louvres 4 are assigned to each louver 2 and are mounted between two bearing plates 5, as shown in German utility model 93 03 875. These air deflection lamellae and their mounting are indicated in FIGS. 2 to 4.
• a cross member 6 is provided, which can be connected on the one hand via a cross 7 to the air outlet 1 and on the other hand via a threaded bolt 8 to the counter bearing.
• the assignment of air outlet 1 to the truss device 6 should be emphasized.
• the cross 7 consists of two intersecting, cross-sectionally oval tube sections 9 and 10, which are penetrated in the middle by the threaded bolt 8 and held together.
• Each pipe section 8 and 9 reaches through corresponding oval holes 11 and 12 or slot-shaped recesses 13 of holding plates 14 and 15, which are inserted into the air slots 2.
• These holding plates 14 and 15 partially replace the above-mentioned bearing plates 5, so that they themselves also have a bearing recess 16 for an axis 17 of the air-gap plate 4.
• a plug-in part 18 which can be formed, for example, from plastic.
• This plug-in part 18 has a head 19 and an insert 20. In the position of use, the head 19 strikes the holding plate 14/15 from the outside, while the insert 20 engages in the tube section 9 or 10.
• a screw or a pop rivet connection can also be used instead of the plug-in part 18.
• FIGS. 5 to 8 two embodiments of holding plates are to be used. 5 and 6, two oval holes 11 and 12 are arranged one above the other, above the oval hole 11 there is the slot-shaped recess 13 mentioned above, in which an actual oval hole is broken outwards.
• both holding plates 14 and 15 have a beveled T-web 21 which, with an actual plate body 22, forms a groove 23 and 24 on both sides for insertion into the air slot 2, as described in German utility model 93 03 875.
• the truss device 6 is fixed in relation to the air outlet 1 in accordance with FIG. 1 as follows:
• Retaining plates 14 are used to fix the truss device 6 or the pipe sections 9 and 10 at their outer end. These can be inserted into the corresponding air slots 2 before the assembly and can carry their corresponding air deflection blades 4.
• the traverse device 6 is then inserted between the holding plates 14 and the corresponding plug-in parts 18 are inserted through the oval holes 11 and 12. In this way, the truss device is pre-attached.
• the holding plates 15 are provided for better support and mounting of the traverse device.
• they are inserted into the corresponding air slots 2 ′′ after the threaded bolt 8, wherein they are first inserted obliquely into the air slots and then turned.
• the tube section 9 When the tube section 9 is turned, it slides into the slot-shaped recess 13 which Axis 17 in the bearing recess 16 and the side edges of the air slot 2 in the grooves 23 and 24. This is a very simple, fast and effective fastening.
