Description

The present invention relates to a mounting plate for a modular wall box, wherein the mounting plate has a front side, a back side and an air passage opening connecting the front side and the back side.

Wall boxes are used to exchange air in order to improve the indoor climate in rooms, particularly in living areas, e.g. in the kitchen or bathroom. "Used" air is discharged from the inside of a building to the outside through an air passage opening in the wall box, while "fresh" air enters the room through the air passage opening. A wall box has a pipe section connected to a mounting plate. The pipe section can be connected to an air outlet pipe on the wall side or at least inserted into a hole in the wall to which the mounting plate is to be attached, with the pipe section itself being connected to the air passage opening in the mounting plate. Since the mounting plate is also used to attach the wall box, the back of the mounting plate faces the wall of the room through which the air exchange is to take place. The front of the mounting plate is arranged opposite the back.

In addition to the basic function of a wall box of allowing air to circulate, wall boxes are also intended to fulfil other related functions. For example, unwanted heat loss, the creation of unwanted drafts, the penetration of dust, insects or pests in general are often to be prevented through the wall box, or the flow properties can be adjusted through the wall box. Which functions of the wall box are most important in each individual case depends on the local conditions at the site of use and also on the customer's wishes. In order for a conventional wall box to be able to fulfil the respective functions satisfactorily, numerous versions of wall boxes are required, each of which is tailored to a specific function and manufactured as a single piece.

If there is a need to change the function of a wall box or to add another function to the wall box, it is currently necessary to replace the wall box with another wall box that is better suited to the changed requirements. The provision However, a large number of wall boxes, each designed for a specific function, is expensive and complex.

The collar 7b-7 of the Figure 3 The adapter 7b shown has a smaller radial width than the collar of the Figure 1 shown adapter 7a. The adapter 7a with the wider collar is used to connect a wall-side ventilation pipe with a smaller inner diameter. The adapter 7b with the narrower collar compared to the adapter 7a is used to connect a wall-side ventilation pipe with a correspondingly larger inner diameter. The outer diameter of the collars 7b-7 is the same for both adapters 7a, 7b, so that they can both be brought into engagement with the adapter holder 6a of the mounting plate 2a. By selecting a suitable adapter 7a, 7b, wall-side ventilation pipes with different flow cross-sections can be connected to the mounting plate 2a in this way.

The adapters 7a, 7b are further designed in such a way that a flap insert 14 can be inserted into the adapter 7a, 7b. For this purpose, the pipe section 7b-6 has an insertion stop 7b-8 on its inside in the form of a radially circumferential web with two diametrically opposed curved sections 7b-9 curved in the axial direction. The curved sections 7b-9 form an axial boundary of recesses 7b-10 arranged in the side wall of the pipe section 7b-6 and extending in the axial direction from the curved section 7b-9 in the direction of the air inlet opening 7b-4. Arranged offset by 90° in the circumferential direction to the recesses 7b-10, the end of the pipe section 7b-6 with the air inlet opening 7b-4 has two diametrically opposed locking pockets 7b-11. The locking pockets 7b-11 are designed in such a way that they can be brought into engagement with locking lugs 14b-1 provided in a flap insert 14. An exemplary embodiment of a flap insert 14b is shown in the Figure 4 shown.

The Figures 4a to 4c include various views of a flap insert 14a with a self-falling ventilation flap, wherein the Figure 4a a perspective view of the air outlet opening 14a-3 of the flap insert 14a without ventilation flap, the Figure 4b a perspective view of the air inlet opening 14a-2 of the flap insert 14a without ventilation flap and the Figure 4c a perspective view of the flap insert 14 with a ventilation flap 14a-5.

The flap insert 14a has an air inlet opening 14a-2 and an air outlet opening 14a-3 as well as a pipe section 14a-4 that connects the air inlet opening 14a-2 and the air outlet opening 14a-3. Inside the pipe section 14a-4 there is a ventilation flap 14a-5 (only in the Figure 4c shown). The ventilation flap 14a-5 is suspended from the pipe section 14a-4 in a self-falling manner such that the ventilation flap 14a-5 can be pushed open in one flow direction by a sufficiently strong air flow through the pipe section 14a-4. If the ventilation flow decreases, the ventilation flap 14a-5 falls back to its original position due to the gravitational force acting on it. The inner cross section of the pipe section 14a-4 is closed by the ventilation flap 14a-5. A stop 14a-9 on the inner side wall of the pipe section 14a-4 prevents the ventilation flap 14a-5 from being pushed open by an air flow from the correspondingly other flow direction. In order to accelerate the closing of the ventilation flap 14a-5, the ventilation flap 14a-5 has a magnetic closure 14a-8 on its lower, outer edge section. The weight of the magnet also encourages the ventilation flap 14a-5 to close due to the force of gravity. A magnetic material 14a-10 arranged opposite on the inside of the pipe section 14a-4 can, together with the magnet, further encourage the ventilation flap 14a-5 to close. By selecting magnets of different strengths, the force that the air flow must apply to push the ventilation flap 14a-5 open can be adjusted.

The axis of rotation of the ventilation flap 14a-5 opens into recesses 14a-7 on both sides, which are arranged in the outer wall of the pipe section 14a-4. In the direction of the air outlet opening 14a-3, the recesses 14a-7 merge into arcuate projections 14a-6, which extend in the axial direction. The arcuate projections 14a-6 are designed in such a way that they can be brought into engagement with the arcuate sections 7a-9, 7b-9 of an adapter 7.

Arranged at a 90° offset from the recesses 14a-7 in the circumferential direction, the pipe section 14a-4 has two diametrically opposed locking lugs 14a-1 on its outside at its end with the air inlet opening 14a-2. If the flap insert 14a is inserted into an adapter 7b, the locking lugs 14a-1 engage in the locking pockets 7b-11 of the adapter 7b. The end of the pipe section 14a-4 with the air outlet opening 14a-3 and the curved projections 14a-6 engages with the insertion stop 7b-8 and the curved sections 7b-9. The air outlet opening 14a-3 is aligned with the air outlet opening 7b-5 of the adapter 7b. The air inlet opening 14a-2 of the flap insert 14a is aligned with the air inlet opening 7b-4 of the adapter 7b. The pipe section 14a-4 of the flap insert 14a rests with its outer surface on the inner surface of the pipe section 7b-6 of the adapter 7b.
