"Nozzle for mounting a ventilation element in a ceiling

or wall opening "

The present invention relates to a socket for mounting a ventilation element in a ceiling or wall opening and is linked to the main claim of the parent application.

The aim of the invention is to further develop the invention according to the parent application, in particular to facilitate rapid assembly and disassembly as well as safe and convenient adjustment of, for example, _{an air supply valve 9,} an air distributor odedglo. '

According to the invention, these tasks are essentially carried out solved the characteristics specified in the claims "

Further characteristics and advantages of the invention will become apparent from the following description made with reference to the accompanying drawings nervous that a favorable ₉ but not limiting Ausführungsbei "represent · =» play There pointers

into a nozzle designated 5, which has the shape of a cylindrical Rohres has. In the embodiment shown, the ventilation element 1 is in combination with the lower or a spatial

LufW facing part of the nozzle 5 a so-called distributor, with the help whose supply air can be distributed and / or directed, for example for the purpose of air conditioning.

The ventilation element 1 has a flat, but somewhat convex plate 8, which is butt-connected to a partially cylindrical insert 9 which is inserted concentrically into the connecting piece 5. In this Pail, "partially cylindrical ¹¹ " means that a basically cylindrical tube is cut open in the longitudinal direction in order to form an opening 10 in the radial direction. As can be seen from Figure 3, the opening width is somewhat differentiated in the longitudinal direction of the insert 9 in such a way that the insert end pushed in furthest in the circumferential direction spans, for example, about 230, while an incision 11 is arranged following this end in the direction of the plate 8, which spans, for example, about 190 in the circumferential direction The insert 9 can stretch plate 8 over, for example, approximately 240 in the circumferential direction and thereby form flaps 12 which are bent slightly outward in order to delimit the lower area of the opening 10, which is not blocked in the radial direction by the connector 5. The flaps 12 can, if desired, with the plate 8 pushed in furthest, bump against a splash or the like 6 , that of the tellema hen end of the connecting piece 5 is formed in order to form a stop au when the connecting piece 5 is pushed into a ceiling or wall opening 4 in a disk 3.

13, which cooperates with the plate 8 and is close to your plate Has roughly the same finish as this one at the end.

The nozzle 5 is on the outside with, for example, two Tongues 7 are provided in diametrically opposite positions or at Arrangement of more than two tongues arranged with the same angular distance are. These tongues 7 are made of resilient material, for example Spring steel, and are preferably triangular, according to a preferred embodiment both the upper and the lower Edge are cut at an angle, i.e. they form an angle smaller than 90 with the nozzle. This has the gate part that the Nozzle 5 into a wall or ceiling opening by a screwing movement 4 with the tongues 7 clinging elastically to the connecting piece 5 can be used «The angle of the bevel cut edges with the nozzle can be between 60 and 45 in a practical embodiment.

The insert 9 and the connecting piece 5 are connected to one another by means of bolts 14 and / or screws 15 »which are preferably about 90 angular spacing in the furthest inserted end of the insert 9 are arranged and penetrate both this and the nozzle 5, wherein in one of these parts, preferably in the insert 9 inclined hats 16 are arranged, for example at an angle of about 60 extend to the longitudinal axis of the connector. The effective expansion of the groove in the longitudinal direction of the nozzle corresponds to the desired change the gap width between the hood 15 and the plate 8,

All grooves 16 are in the same direction in the circumferential direction inclined, which according to FIGS. 3 and 1 means in the direction of the plate and in the same direction as the tongues 7 extend from the nozzle 5

ken. This has very special advantages of the setting, which are to be explained in the following:

If the connection piece 5 with an inserted ventilation element is to be attached in a wall or pool opening 4, this can be done with the help of just one hand of a skilled fitter. It is only necessary to insert the free end of the connecting piece fj and then using the palm of the hand to turn the plate 8, which transfers the torque to the connecting piece 5 and the tongues 7 via the insert 9. Although the insert 9 rotates somewhat in relation to the socket 5 'until the rivet and / or the screw have reached their upper end position in the grooves 16, the torque is then transferred undiminished to the socket 5 and the tongues 7, which in the opening 4 are screwed in until the bevels of the tongues 7 close to the ridge slide past the rear side 2 of the opening 4, the tongues 7 aligning themselves automatically and locking the nozzle 5 with ventilation element in said opening 4, and the opening 4 in the throat area between the the bevels of the tongues 7 and the puddle 6 come to rest close to the hood «

In this way you have a very quick and easy installation of a nozzle with a ventilation element in an opening, which opening can also vary within wide limits.

If you want an exact gap width that can be preset, you have this beforehand by tightening the screw 15 as described above Insertion process fixed.

However, if the gap width between the hood 15 and the To adjust plate 8 after insertion, you only need to take the plate 8, which is in its opposite to the hood 13 on furthest inserted position is, and to rotate the plate counterclockwise in the embodiment shown, so that the rivet

§09822 / 0394

14 and the screw 15 in the hats 16 move down until the desired Gap width is reached. The torque exerted here on the plate 8 is not transmitted to the connecting piece 5, and so on possibly canceled, since the torque from this opening movement is directed against the tongues 7, since these are tangentially clockwise protrude from the nozzle 5 and said opening movement as I said in Counterclockwise happens. The tongues 7 pinch themselves here and thus the connecting piece is fixed to the wall material surrounding the opening 4, so that it is impossible to turn the nozzle.

However, if you want to reduce the gap width again, it is sufficient to push the plate 8 in the longitudinal direction against the hood 15, there the flange 6 or the like as a reliable stop against the wall. 3 works.

Thanks to the invention, it is thus possible to assemble and dismantle a connection piece with a ventilation element in a simple but very reliable manner and completely without tools, and to adjust it without any restrictions. At the same time, however, the possibility is kept open again / without a factory eye to remove the entire nozzle with yentilatioas element, for which purpose one grabs the hood 13 together with the head 8 and rotates both in a clockwise direction, with the bevels of the tongues 7 ^{near the hood out of} the opening 4 slide out in order to finally be detached from the opposite slopes and then to release the entire socket «

Embodiments described above and shown in the drawing figures are to be regarded only as non-limiting examples that can be modified within the scope of the inventive idea and the following claims in any manner and completes ₀
