Description

MULTI-PIECE VARIABLE REVISION DEVICE IN THE SURFACE EXTENSION

The invention relates to a revision device, in particular Revision cover, with a revision frame with frame profile and an applicable here inspection cover with Deckelprofϊl, and with a panel for the revision frame and / or the inspection cover.

Such revision devices have become generally known in practice and, for example, by EP 1 516 978 A1. In general, revision devices serve to provide an opening in a wall paneling, ceiling panel or floor paneling with a closable flap to permit subsequent access to installations, conduits, etc. located behind the panel. The cladding may be conventional insulation boards, plasterboard, mineral fiber boards, but also wood panels, plastic sheets, steel plates and combinations.

Due to the different requirements of the particular site a variety of different revision devices are realized in practice, which differ for example in size, depending on how large the opening to be closed is designed. Also, different inspection devices are implemented to meet requirements of the structure with regard to fire protection, sound insulation, radiation protection, disinfection contactor, etc. So far, one has tried to master these various needs, each with differently designed inspection devices, which of course makes the production and storage difficult. - This is where the invention starts.

The invention is based on the technical problem to develop such a revision device so that can be used on continuous standard components, so that in particular the manufacturing and storage costs are reduced.

To solve this technical problem, the subject of the invention is a generic revision device, which characterized is that the panel is at least variable in terms of their surface area and multi-part with at least one central standard plate and randsei- term corner and / or filler plates for flexible size adjustment of each area to be covered is formed.

In the context of the invention, it is therefore primarily a matter of finding the most flexible solution possible for the cladding of the inspection cover and / or the revision frame, which can also be used with differently designed inspection devices. In particular, the focus is on a flexible (surface) resizing of the cladding to realize. For this purpose, the cladding is formed in several parts and is composed of the questionable central standard plate and the marginal corner or filler plates together. Advantageously, the corner / filler plates together form a frame for the standard plate arranged in the middle.

For this purpose, the corner / Füllplatten have about the same plate thickness compared to the central standard plate. As a result, a consistent by their strength forth panel is provided which completely fills, for example, the interior of the inspection cover. Of course, the inspection frame can also be equipped with such a covering, which is flexible in terms of its surface area. However, most of the revision frame is fixed to the already existing wall, ceiling and / or floor covering, so that in this case only an additional panel for the inspection cover is required. The fact that this panel is made variable in total area by their multi-part design, very different lid sizes in the example case can be taken into account.

Because the invention usually falls back on one and the same central standard plate and only varies the marginal Eck- / Füllplatten to provide the required cover for a revision cover available. The central standard plate is usually designed by their dimensions so that it fits, for example, flush in the smallest possible inspection cover. Other, larger inspection covers are also equipped with said central standard plate, which then undergoes an areal enlargement through the edge corner / Füllplatten. In fact, these corner / filling plates may be plates which cover corner regions of an area enclosed and to be filled by the cover profile in the example case. On the other hand, the filler plates mostly serve to close free spaces left between the corner plates. Of course, combined corner / filler plates can be used, which cover both the corner and the respective or more free spaces. In addition, it is understood that the corner and / or filler plates do not have to form a peripheral frame for the central standard plate, but may be equally well spaced apart from each other. Moreover, it is of course within the scope of the invention to work with a one-piece corner / Füllplatte as it were frame for the standard plate.

In any case, it is recommended that the corner and / or filler plates are fixed to mounting legs of the frame profile and / or the cover profile. These attachment legs usually form the respective profile in conjunction with visible legs. In this case, fastening legs and legs are usually perpendicular or at least angled to each other. In this way, the frame profile and / or the cover profile can be formed in cross-section L-shaped or T-shaped. Also, a U-shaped in cross section design is conceivable, wherein at least one U-legs is designed as a visible leg and the U-base forms the mounting leg. Likewise, combinations of the aforementioned profile designs are conceivable.

In order to achieve a continuous cladding, it is recommended that the standard plate and the corner / filling plates abut each other. In addition or as an alternative, however, it is also possible for a connection, for example a positive connection and possibly a detachable connection, to be present at this point between the standard plate, the corner plates and optionally the filler plates. It has proven useful if the connection in question is designed as a tongue and groove connection. Preferably, tongue and groove extend in the frame or lid plane. For example, the central standard plate can be equipped with a circumferential spring or with a plurality of spring sections at its periphery, which in an associated circumferential groove or more Engage individual grooves of the corner / Füllplatten that frame the questionable central standard plate.

In addition to the described surface flexibility of the multi-part cladding according to the invention, height flexibility of the cladding in question is also advantageously observed. This means that the cladding can also be constructed in several parts in terms of their height extension and composed of several layers. So that these layers do not move or are fixed relative to one another, they can be coupled to one another by form-fitting connections and / or continuous connection means. It is recommended that the connecting means in question not only provide for a coupling of the layers with each other, but at the same time determine the overall panel on the frame profile or cover profile. Then the connecting means are simultaneously designed as fastening means.

In addition to the surface flexibility and height flexibility of the multi-part panel according to the invention described above, it has been proven that in addition the revision frame and / or the inspection cover are constructed of interconnected profile pieces. These profile pieces may each be designed as extruded sections, bending stamped parts, etc. It is recommended that the profile pieces can be made almost in one step completely, and indeed with a given length. In this way, the revision frame or the inspection cover with virtually any area size can be defined by means of the interconnected profile pieces. Depending on the surface size of the inspection cover or the revision frame then the selection of Eck- / Füllplatten is done in order to upgrade the central standard plate in terms of area so far that the entire surface to be covered is filled.

The work in question, that is, the connection of the profile pieces and the cover of the surface defined by the profile pieces, can be made on site, that is, immediately during installation. As a result, the revision device according to the invention is not only suitable for a planned installation, but also and in particular for retrofitting. Moreover, the individual parts of the multi-part panel can be easily adapted to topological characteristics, this no longer the entire panel must be edited. For example, notches, millings or the like for a possible closure, for hinges, etc., can be easily introduced into the corner / filling plates. This can be done much easier than if a total of a voluminous paneling would have to be processed in one piece.

In addition, the not only variable-area, but also variable-height design of the multi-part paneling according to the invention not only makes it possible to react flexibly to different surfaces to be covered, but also expressly allows changing structural-physical requirements to be satisfied. Thus, depending on the required fire protection, sound insulation, radiation protection or disinfection protection, etc., the entire thickness of the cladding can be changed by combining several layers of the cladding on top of each other. Finally, it is also easy to incorporate receiving grooves, etc., into the panel according to the invention in order, for example, to be able to receive the fastening leg of the frame profile or cover profile in a protected manner. As a result, as it were thermal insulation of the leg in question is achieved and increased overall fire safety and consequently the fire protection class. Here are the main benefits.

In the following the invention will be explained in more detail with reference to an exemplary Ausführungsbei- game drawing; show it:

1a is a plan view of a revision device according to the invention,

FIG. 1b shows a modified embodiment according to FIG. 1a,

Fig. 2 is a view of Fig. 1 in the corner of the inspection cover and

Revision frame in section and

3 shows a schematic cross section through FIG. 1 in the gap area. In the figures, a revision device is shown, which is designed in the context of the example and not restrictive as a revision cover. The revision device or revision cover in question is composed of a circumferential revision frame 1 with frame profile 2 and an inspection cover 3 with cover profile 4 which can be inserted into the revision frame 1. For the basic structure still includes a panel 5 for the inspection frame 1 and / or the inspection cover. 3

According to the invention, the lining 5 is designed to be variable in area and in several parts. In addition, and as an option, the panel 5 is also made variable in height. The surface variability of the cladding 5 is achieved in that it consists of a central standard plate 5a and edge-side corner plates 5b and filler plates 5c, 5d for flexible sizing of the surface to be covered. The surface in question is in the exemplary embodiment to the enclosed by the cover profile 4 surface of the inspection cover 3. Of course, in addition, the inspection frame 1 are equipped with its frame profile 2 with a corresponding panel 5, which is not shown.

It can be seen in detail that the corner plates 5b and the filler plates 5 c, 5 d taken together form a frame 5 b, 5 c, 5 d for the contrast central standard plate 5 a. Within the scope of the exemplary embodiment and not necessarily, the frame 5b, 5c, 5d in question is designed as a continuous frame, because the individual corner plates 5b and filling plates 5c, 5d abut one another abutting one another. Incidentally, the corner plates 5b are advantageously formed almost square, whereas it is at the filler plates 5c, 5d are each rectangular main body. Of course, the corner plates 5b and the filler plates 5c may also be combined, if necessary, as shown in FIG. 1b. Then, a corner plate 5b and a filling plate 5c, 5d are combined to form a combined corner / filling plate 5b, 5c and 5b, 5d, respectively.

In any case, in the context of the invention, the corner plates 5b and the filler plates 5c, 5d have an approximately equal plate thickness in comparison to the central standard plate 5a, so that the casing 5 as a whole or its insert Parts 5a, 5b, 5c, 5d form a continuous flat surface. In this case, it has proven to be a good idea if the corner plates 5b and the filler plates 5c, 5d are fixed to attachment legs 4b of the inspection cover 3 or its cover profile 4 and / or to attachment legs 2b of the revision frame 1 or its frame profile 2. With reference to FIG. 3 it can be seen that the respective frame profile 2 and the cover profile 4 are formed in each case in cross-section L-shaped. The L-shape is in this case formed by the said attachment leg 2b, 4b in conjunction with an associated visible leg 2a, 4a. Visible legs 2a, 4a and fastening legs 2b, 4b are each perpendicular to one another with the formation of the L-shaped frame profile 2 and cover profile 4.

To fix the corner plates 5b and the filler plates 5c, 5d to the fastening legs 2b, 4b in question, continuous connecting means 6 are provided in the exemplary embodiment. In the present case, these connecting means 6 are at least in part fastening means 6, ie means which simultaneously ensure that the part or covering part 5a, 5b, 5c, 5d in question is attached to the associated frame profile 2 or cover profile 4.

The standard plate 5 is also coupled to the corner plates 5b and filler plates 5c, 5d, for example, by connecting means 6. In the context of the embodiment and according to the preferred embodiment, however, are the standard plate 5a and the corner / Füllplatten 5b, 5c, 5d not abutment against each other, but is a compound 7, 8 between the one hand, the standard plate 5a and on the other hand, the corner / Füllplatten 5b, 5c, 5d, which surround the central standard plate 5a in the manner of a frame. The connection in question 7, 8 is executed in the embodiment as a tongue and groove connection 7, 8 and shown primarily in FIGS. 2 and 3. As a result, a connection 7, 8 that is at the same time form-locking and possibly detachable can be represented.

In detail, the associated groove 7 and the spring 8 generally extend in a plane defined by the revision frame 1 and the inspection cover 3, respectively. In the exemplary embodiments, this frame or cover plane coincides with the drawing plane according to FIGS. 1 and 2. One gets knows that in the present case, the central standard plate 5a is equipped with a circumferential spring 8, which engages in a likewise circumferential groove 7, the edge of the frame of the corner plates 5b and the filler plates 5c, 5d is formed. In addition, the connecting means 6 ensure that the connection in question 7, 8 is fixed. Of course, this can also be accomplished such that between groove 7 and spring 8 an adhesive agent for the necessary coupling on the one hand of the standard plate 5 a on the other hand, the frame 5 b, 5 c, 5 d provides. - It is understood that the tongue and groove connection described 7, 8 can also be used for coupling the corner plates 5b and the filler plates 5c, 5d to the frame 5b, 5c, 5d in this or another embodiment.

As already described in the introduction, the panel 5 is not only surface variable, but also constructed variable in height in the context of the embodiment. For this purpose, the cladding 5 has, with respect to its height extension, a plurality of layers 9 arranged one above the other, which are recognizable in particular in FIG. The individual layers 9 can in turn be coupled together by means of continuous connecting means 6. In this case, the structure in FIG. 3 is even chosen so that the cladding 5 has a total layer thickness D which exceeds a free space F between a head-side end of the respective viewing leg 2a, 4a and the mounting leg 2b, 4b. In this way, as shown in FIG. 3, the respective fastening limb 2 b, 4 b can be received in a groove 10 within the cladding 5 or the fastening leg 2 b, 4 b in question can be correspondingly covered. This increases the fire protection effect enormously.

In the questionable Fig. 3 can be seen in addition to two attached to the respective profile 2, 4 Blähstreifen 11, which close a gap S between the inspection frame 1 and the inspection cover 3, for example in case of fire. - Both the frame profile 2 and the cover profile 4 can not only be L-shaped in cross-section, but alternatively or additionally also U-shaped or T-shaped. In addition, it has proven to be advantageous if the respective profiles 2, 4 are constructed of interconnected profile pieces. These profiled pieces, which are particularly recognizable in FIG. 2, can be easily interconnected, for example, by means of split pins on the one hand to the revision frame 1 and on the other hand connect the inspection cover 3. Thereafter, only the panel 5 needs to be mounted on the inspection cover 3 in the example case to complete the inspection device as a whole. This can also be done later on site.
