Description

The invention relates to a wall box with a cover and an installation method for mounting the wall box.

A wall box provided with a cover is inserted into a wall to create a passageway between the interior and exterior of a building through which air can be directed away from the building in a controlled manner. Typically, a wall box is provided in an outer wall of a kitchen to convey the collected from an extractor hood exhaust air from the range of the cooker to the outside or supply fresh air from the outside.

The EP2600074A1 and the GB2465029A each reveal a wall box with a ventilation pipe and a cover. By means of the covering device, the ventilation pipe, which can be used in a running from the inside to the outside of a wall opening, are covered so that exhaust air escape to the outside, rainwater but can not penetrate. The cover devices have two connected by a hinge and held by a mounting rod cover elements, which can be folded against each other through the vent tube feasible and outside the wall unfolded and pulled in the unfolded state against the outer wall of the wall to cover the wall box and the vent pipe ,

From the WO0248620A1 Another cover device is known with two interconnected by a hinge cover elements by hand in the folded state passed through a vent tube to the outside of a wall, folded and pulled back against the outer wall to close the vent pipe.

A disadvantage of these devices is that of a rod or manually held cover device is not easily manipulated and displaced to a desired position. It should be noted that the wall box is often not easily accessible, which further complicates the manipulation. In addition, the person performing the manipulation has no view of the outward-directed cover, and therefore many attempts are often necessary until the installation can be completed.

Furthermore, it should be noted that the known covering devices are designed consuming and are manufactured with relatively high production costs.

The present invention is therefore based on the object to provide an improved wall box with a cover and to provide an improved installation method, with which the wall box and the cover device can be installed advantageously.

In particular, a wall box is to create, which can be inexpensively installed and maintained with minimal effort and maintained. In particular, the associated cover device should be inexpensive to produce and install with minimal effort quickly and accurately.

The installation of the cover should be quickly and easily by means of a tool or manually carried out. The installation with a handle or a movement should be able to be safely performed without several attempts are necessary.

The covering device should be able to be installed precisely and tightly next to the wall opening.

The elements of the wall box should be made in a simple manner from sheet metal without expensive tools are required.

This object is achieved with a wall box and an installation method which have the features specified in claims 1 and 14, respectively. Advantageous embodiments of the invention are specified in further claims.

The wall box comprises a ventilation pipe, which is insertable into a wall opening, which runs from the inside to the outside of a wall, as well as a covering device, which can be displaced outwardly through the ventilation pipe and positioned in front of the ventilation pipe.

According to the invention, the ventilation pipe has a guide rail, of which a guide carriage is displaceably held, which has a guide part held by the guide rail and a holding part, which is connected by a hinge element with the cover device.

The wall box according to the invention makes it possible to install the covering device simply and precisely. Once the building, ie the masonry, the exterior and any installations are completed within the building, the cover can be installed easily. For this purpose, the guide carriage along the guide bar is moved outwards and back again. In this process, the covering is first led to the outside of the wall opening, where appropriate unfolded, tilted by gravity and in the sequence led back against the vent pipe to this and to cover a bordering the wall opening edge of the outer wall. It is thus no difficult manipulations of the covering required, but only a simple linear displacement of the guide carriage back and forth, which can be completed manually or by means of a tool. In this installation process, the cover is outside the building wall automatically accurate, preferably aligned coaxially with the vent pipe and returned to this. The position of the cover automatically results according to the construction of the guide carriage and the connecting elements. A move and a middle of the installer is not required but is positively guided.

Preferably, flange elements are provided on the wall facing the side of the cover, which connect after installation of the cover to the inside of the vent pipe and secure the cover.

The said installation process can also be carried out without visual contact by the guide carriage is moved along the guide bar, without the process is visually monitored. The installation of the cover can thus be completed easily, if the wall opening is not easily accessible and no optical insight allowed.

According to the method according to the invention, the wall box with the ventilation pipe and together with the covering device slidably mounted therein by the guide carriage are walled into the masonry.

Preferably, an insulating layer is provided in the respective wall opening, which the ventilation pipe from Masonry separates. Before installing the wall box in the masonry, the ventilation pipe is preferably provisionally covered on the front and back, so that no water and no foreign matter can penetrate into the pre-assembled wall box. After completion of the structure, the covering device can be routinely installed as a result within the shortest time in the manner described above. The temporary covers are removed and the guide carriage with the cover is pushed forward along the guide rail. Connecting pipes of any kind can be connected to the wall box by suitable adapters.

The usual in the prior art work of introduction and manipulation of the covering, requiring a skilled person, completely eliminated. The installation of the wall box in the masonry and the subsequent installation of the covering in the walled-in wall boxes can be performed by untrained auxiliary personnel or persons who install the devices to be connected to the wall box.

The covering device is preferably a one-piece, optionally multi-part grid or weather protection grille, which has, for example, horizontal slots and lamellae. So that covering devices or grids can be installed with a larger cross-section, these are preferably folded and / or elastically bent introduced into the ventilation pipe. As soon as the covering device is ejected from the ventilation tube, the covering device can unfold again. By subsequently pulling the cover against the wall box, which is preferably overlapped on all sides by the cover, the cover can again in one level aligned and tightly pressed against the edges of the wall opening.

The entire wall box with the vent pipe, the guide carriage and the cover can be made in a simple manner from sheet metal. Preferably, stainless, resilient sheet having a thickness of e.g. 0.3 mm to 0.75 mm. It is also possible to use different materials for each element. For example, It is also possible to manufacture the said elements made of plastic. The vent tube, the guide carriage and the cover can advantageously be made from only one piece of sheet metal. In further embodiments, the vent tube and / or the guide carriage and / or the cover device can also be made of two or more pieces of sheet metal, the articulated, e.g. by means of a hinged joint, or fixed, e.g. by means of rivets or Toxen, to be connected with each other.

The ventilation pipe, which has a round or polygonal, for example rectangular or square, channel cross-section, can advantageously be bent from a single piece of sheet metal. It is provided that two opposing and mutually parallel end pieces of the sheet metal piece are guided against each other and aligned by folds in the channel cross section inside. The two adjoining end pieces, which are preferably each provided with a guide slot, form in the sequence the guide bar, along which the guide carriage is displaceable back and forth. The guide slots or other mounting elements can be inserted in advance in the cut sheet. For example, also hooks or receiving openings can be incorporated into the sheet, optionally cut into it and bent out.

If a round channel cross-section is provided, only folds in the mentioned end pieces are required. If a rectangular ventilation pipe is to be manufactured, four folds are provided at the corners and two folds on the end pieces and a respective folds on one of the end pieces, which together form the guide strip.

Also, the guide carriage can be made particularly advantageous from a piece of sheet metal. For example, one or two legs are bent down to form the guide member. In addition, one or two legs are bent up to form the holding part.

The guide member and the holding member may be arranged one above the other or offset from one another and connected to each other by a connecting web. The connecting web, if present, is preferably elastic, so that the holding part is pulled elastically after installation with the cover back against the outer wall.

The drive part sits eg as a rider with two legs on the guide rail or is held for example with a leg in a guide channel of the guide rail. The drive part can thus be stored in a simple manner in or on the guide slot and be held displaceably with at least one coupling element. For example, at least one bearing pin is guided through openings in the drive part and through the guide slot in the guide strip, which can be guided in the sequence within the guide slot forward and back. If the guide carriage is held with two bearing pins which are held spaced apart in the guide slot, the guide carriage is always guided with the same orientation back and forth.

The cover device is preferably made of a single piece spring plate, which is resiliently bendable and can be arranged in a bent state within the ventilation tube. Preferably, a hinge joint is avoided with a bearing shaft, which significantly reduces the manufacturing cost. In preferred embodiments, however, bending lines, such as grooves and grooves, can be incorporated into the spring plate, which serve as bending joints in the sequence. The cover device is preferably provided with slots and inclined blades, which ensure sufficient air transfer and at the same time prevent the ingress of water.

In preferred embodiments, a drip rail is provided on the underside of the cover or the ventilation pipe, which drains rainwater to the outside and does not slide along the wall.

In a further preferred embodiment, a self-contained sealing frame is provided on the inside along the edge of the cover, which rests after the installation of the cover at the edge of the wall opening and this closes tightly. This prevents exhaust air from escaping from the edges and causing dirt to the façade.

The covering device preferably has a connecting part, which is connected by a hinge element, preferably a horizontally oriented hinge pin, with the holding part of the guide carriage, so that the covering device can tilt from the horizontal position within the ventilation tube in a vertical position outside of the ventilation tube.

The connecting part which can be produced by folding the covering device is preferably along the central axis the cover device arranged eccentrically. After the expulsion of the cover this is therefore not in balance, but has in its lower part below the tipping point a greater weight, which is why the cover front tilts automatically down to the vertical position.

The guide carriage can therefore be moved and locked manually or by means of a tool back and forth. The locking element may be, for example, a hook or an elastic element which is attached, for example, to an element of the ventilation pipe. The guide carriage can have a flexibility, so that the covering is pulled elastically against the outer wall of the wall.

Alternatively, an elastic element, e.g. a spiral spring, are connected to the guide carriage, through which the guide carriage is pulled backwards. The coil spring may e.g. be hung in a hook, which has been cut out of the ventilation pipe and bent.

Fig. 1 shows that from the EP2600074A1 known wall box with a wall 9 arranged in a ventilation pipe 2 ', within which a cover 1' by a rod 15 'is held. The cover device 1 'has two by a hinge 13' interconnected cover 11 ', 12'. To assemble the cover device 1 ', it must be turned outwards by means of the rod 15' and withdrawn again in order to close off the ventilation pipe 2 '.

This installation process is associated with difficulties, since the holding, turning, unfolding, positioning and fixing of the cover without looking at the kept cover 1 'is to complete. Experienced personnel is required, which nevertheless probably requires several attempts to install the cover device 1 '. A routine and safe installation of the cover device 1 'with only one and movement is not possible.

Fig. 2a shows a wall 9 with a wall opening 90, in which a wall box according to the invention is used, which has a rectangular ventilation pipe 2, which is enclosed by an insulation 8 and which has a guide rail 21. Further, a guide carriage 3 is provided, which has a guide member 21 slidably held on the guide member 31 and a holding part 32 which is connected by a hinge axis 72 with a cover 1, which has a sheet metal grid 10 and a connecting element 19, of the hinge axis 72nd is held rotatably. The sheet metal grid 10 is held within the ventilation tube 2 and bent down on both sides of the connecting element 19.

By using resilient thin sheet 10, which is bent downwardly on both sides of the connecting element 19, it is possible to provide a sheet metal grid 10 with a cross section which is significantly larger than the cross section of the wall opening 90. After installation, the sheet metal grid 10 overlaps therefore the ventilation tube 2, the insulation 8 and a rim 91 of the wall 9 adjacent to the wall opening 90, as shown by a dot-dash line (see also FIGS Fig. 2b ).

Thus, between the wall 91 adjacent to the wall edge 90 of the wall 9 and the sheet metal grid 10 is a tight-fitting Connection results, the sheet metal grid 10 is provided at the edge with a peripheral sealing frame 80 (see Fig. 6b ), which is preferably elastic.

According to the inventive method, the wall box in the erection of the masonry 9, preferably as Fig. 2a shown mounted together with the mounted cover device 1 as a module in the masonry 9 and in a wall opening. Preferably, the ventilation pipe is enclosed by an insulation. Until the final installation of the covering device 1, the front side and the rear side of the ventilation tube 2 are preferably covered by provisional covers or dirt caps made of plastic, so that dirt and water can not enter.

After completion of the building and the outer facade, the cover 1 may be ejected and guided in front of the wall box to cover the wall opening 90, as shown in Fig. 2b is shown. The cover device 1 with the sheet metal grid 10, which has two rows of longitudinal slots with louvers 100, is in front of the wall opening 90 and with the sealing frame 80 (see Fig. 6b ) tightly held at the wall edge 91. Furthermore, it is shown that the covering device 1 has a drip edge 101 on the underside. For this purpose, the underside of the sheet metal grid 10 can be folded forward. Alternatively, the lowermost slat may be made longer than the other slats.

In preferred embodiments, the vent tube 2 comprises at least two telescoping sub-tubes, which can be pulled apart or moved into each other to adapt the vent tube 2 to the length of the wall opening.

Fig. 3 shows the ventilation pipe 2 of Fig. 2 that in this preferred embodiment has a rectangular cross-section. The ventilation pipe 2 is made of a single piece of sheet metal and has six folds. Identical end pieces of the sheet, each having a guide slot 210 are directed parallel to each other against the center of the vent pipe 2 and form a guide rail 21. The end pieces may be connected to each other, for example, by Tox compounds or rivets or held together by the guide carriage 3 ( please refer Fig. 4 ) become.

Behind the vent tube 2, an adapter plate 20 is provided, which is adapted to the cross-section of the vent tube 2 and which has a coupling tube 200 into which a connection tube, e.g. a steam extractor can be used. The adapter plate 20 may be formed in a known manner, e.g. tightly inserted through terminals and screws in the vent tube 2 or placed on it. From the ventilation pipe 2 can e.g. Rims are exposed and bent inward to form flange elements for mounting the adapter plate 20. Between the flange elements and the adapter plate 20, a further sealing frame is preferably provided.

Fig. 4 shows a schematic representation of the covering device 1 and the guide carriage 3 of Fig. 2 which is integrally formed from a sheet metal and which has a guide member 31 connectable with the guide member 31, a connectable to the cover 1 holding member 32 and a mounting part 33, by means of which the guide carriage 3 can be manipulated and fixed.

In the legs of the guide member 31 openings 310 are provided, in which a bearing pin 71 is used, the is guided through the guide slot 210 in the guide rail 21 (see Fig. 3 ).

In the legs of the holding part 32 openings 320 are provided into which a hinge pin 72 can be inserted, which can be passed through an opening 190 in the connecting part 19 of the cover device 1 shown schematically and rotatably holding the connecting part 19.

The guide carriage 3 also has a coupling part 33 with a preferably provided coupling opening 330. The coupling part 33 makes it possible to couple a tool, a locking element or a preferably elastic retaining element to the guide carriage 3 in order to manipulate, lock or hold it in position.

The guide carriage 3 with all parts 31, 32 and 33 can be advantageously made from a piece of sheet metal. The openings 310, 320, 330 can be introduced into the piece of sheet metal before it is bent.

The symbolically shown covering device 1 comprises the sheet metal grid 10, which is preferably likewise manufactured from only one piece. For this purpose, slats 100 are preferably cut and bent. At the lower end, preferably a drip rail or drip edge 101 is bent.

Fig. 5a shows the wall box of Fig. 2 in a longitudinal section along the line A - A with the retracted guide carriage 3 and one half of the cover tube 1 held inside the ventilation tube 2. It can be seen that the cover device 1 or the metal grid 10 could still be provided with larger dimensions to a cover wider edge of the masonry 9.

The guide carriage 3 comprises a connecting web 34 which connects the guide part 31 with the holding part 32. The connecting web 34 is supported on the guide rail 21 and thereby kept stable. Alternatively, the connecting web 34 may also be formed resiliently and held above the guide rail 21, so that the covering device 1 can be pulled elastically against the masonry 9 after installation. The connecting web 34 serves as a spring.

The guide rail 21 with the guide slot 210 is formed such that the held with two bearing pin 71 guide member 31 of the guide carriage 3 can traverse almost the entire wall opening 90.

The holding part 32, the connecting part 19 and the hinge element or the hinge pin 72 are dimensioned or arranged such that the cover device 1 automatically tilts to cover the wall opening 90. In Fig. 5 are the resulting upon tilting of the covering device 1 around the hinge pin 72 circular lines showing the expected coverage of the wall opening 90 adjacent edge of the masonry 9.

Fig. 5b shows the wall box of Fig. 5a after extension of the guide carriage 3, which is held by two bearing pins 71 in a horizontal orientation, during the tilting of the cover 1. Due to the arrangement of the sheet metal grid 10 eccentric to the connecting element 19, the cover 1 tilts automatically down. As a result, the expected orientation of the cover device 1, which results in Fig. 5a indicated by circles.

In this embodiment, the coupling element 33 of the guide carriage 3 with a rod-shaped tool fifth is connected, by means of which the guide carriage 3 can be manually moved back and forth. It is also possible to design the coupling element 33 such that it can be detected directly manually (see Fig. 5d ). The tool 5 may be formed in one piece, multi-part or telescopic.

Fig. 5c shows the wall box of Fig. 5b with the cover 1 in a vertical position.

Fig. 5d shows the wall box of Fig. 5c After the return carriage 3, the cover device 1 or the sheet metal grid 10 rests with the sealing frame 80 at the edges of the wall opening 90 and covers the vent tube 2 and the seal 8 completely. The coupling element 33 is connected by a spring 6 to a holding element 25 which has been formed, for example, on the rear side of the ventilation tube 2. The spring 6 pulls the guide carriage 3 and thus the cover device 1 with the sealing frame 80 with a constant force and thus tightly against the outer wall of the wall. 9

In the embodiment of Fig. 5d It is shown that the coupling element 33 can also be detected manually. The guide carriage 3 is optionally pushed against the force of the tension spring 6 forward, so that the cover 1 can tilt in front of the masonry. As a result, the manual pressure on the guide carriage 3 is released so that it can drive back under the action of the tension spring 6. The entire installation process can therefore be carried out with a single simple manual intervention, ie a pushing forward movement.

Fig. 6a shows a one-piece sheet metal cover device 1 seen from above. The connecting element 19 connects two cover elements 11, 12, which by elastic Deformation of the connecting element 19 can be rotated against each other. The connecting element 19 can also be positively and / or non-positively connected, optionally by a screw connection or welded connection with the sheet metal grid 10. The connecting element 19 can also be passed through the sheet metal grid 10 and anchored thereto.
