Flush box

The innovation relates to flush-mounted boxes for the Installation of electrical or electronic equipment.

The innovation is based on the task of inserting or pouring the concealed box or plastering the Masonry to prevent the penetration of mortar or dirt into the interior of the flush-mounted box.

To solve this problem it is proposed according to the innovation, To provide the flush-mounted box with a glued-on cover for assembly, which is removed after assembly and is thrown away.

The cover can protrude with one edge or several edges and fastened to the inside of a casing will.

For this purpose, through holes for liägel or wood screws can be made in the protruding edges of the cover are provided.

The flush-mounted box is essentially rectangular, and the edges of the flush-mounted box that run perpendicular to the cover are, at least in the area of the
Back, beveled or rounded.

It is advisable to use threaded bushings that are integrally formed in the area of the beveled or rounded edges absorbent or educational approaches are provided.

For mounting the flush-mounted box or for insertion or pouring the same into the masonry can extend between the long side walls perpendicular to these Support bar can be provided, which is removed and thrown away after assembly. The support leg is appropriate loosely inserted into guide grooves in the side walls.

There can be protrusions on the inside of the box bottom for or as threaded bushings.

The cover and optionally the support strip, since they are thrown away after the installation of the flush-mounted box, made of a cheap material, for example from a
Hardboard to be cut out.

The innovation will now be explained in more detail with reference to the drawing showing them for example shows

Fig. 1 a cast in a concrete wall flush box before stripping, while

Pig. 2 is a view looking at arrow II in FIG Figc 1 reproduces the sub-box without a cover.

The flush-mounted box 1 shown is rectangular and has two long side walls 2, two short side walls 3 and a box bottom? 4years. To protect against penetration of mortar into the interior of the flush-mounted box 1, a cover 5 made of hardboard or the like is on the strands of the side walls 2 and 3. glued. With two edges, the cover 5 stands over the short Se? jenwand 3 in front, and through holes 7 for nails 8, preferably made of copper, or stainless wood screws are provided in these edges 6, with which the flush-mounted box 1 glued to the cover 5 can be attached to the inside of a cladding 9.

After the flush-mounted box 1 has broken out holes 10 (see Pig. 2), 3eton .2 is poured into the switched-on room, the 3eton mortar tightly enclosing the flush-mounted box 1 and the cable ducts 11 when it is compacted.

So that the long side walls 2 are not pressed in by the pressure of the concrete mortar and thus the glued on Lid 5 is not prematurely released from the flush-mounted box, a support line 13 is provided, which is between the side walls 2 and extends perpendicular to these and inserted loosely into guide grooves 14 of the side walls 2 will.

The edges 15 of the, which run perpendicular to the cover 5 Concealed box 1 are from the box bottom 4 (i.e.

in the area of the back) on most of their Sloped length to facilitate concrete flow. In the area of these bevels 16, approaches 17 are integrally formed. These approaches 17 form for Cover 5 open towards threaded sockets or take on such. In the; e threaded sockets can already be glued on of the cover 5 screws are screwed in, which will later be used to attach a suitable chassis to it attached electrical or electronic components to serve.

The Unterputζkästen 1 described can also be used in a conventional manner in wall recesses, for example plastered, with a lid 5 without over- ■ standing edges 6 is used, which is also glued to the flush-mounted box 1 and which is flush with the wall Inserting the flush-mount part 3 \ :. ens 1 facilitates as well as that Penetration of mortar or dirt into the interior of the same is prevented. You can here the cover 5 with a weaker one Stick on the adhesive to ensure that the To facilitate the tearing away of the cover 5 from the flush-mounted box 1.

The flush box 1 serves iu. primarily for Recording of apartment or door intercoms. Ss can but also, for example, a Klingex transformer and a gong can be accommodated in it. These are on the On the inside of the box bottom 4, a plurality of projections 13 are provided, which receive or form threaded sockets.

Tests have shown that after pouring the flush-mounting box 1, as in Pig. 1 shown, the Lid 5 when stripping with the ^ unilaterally detached)

* ■ -

Cladding 9 from the flush-mounted box 1, starting at the top glued edge, lets tear loose. This is particularly advantageous with exposed concrete. The integrity of the exposed concrete surface is preserved, and the installation is completed by pouring the flush-mounting box 1 with the cable ducts 11, as no special concrete recesses are necessary for later installation.

After removing the cover 5 when stripping the formwork, the support strip 13 is taken up and thrown away, there it is no longer necessary to support the long side walls 2 after the concrete has set C.

The innovation also relates to modifications of the embodiment outlined in the attached claim 1 and relates above all on all new features, which are disclosed individually - or in combination - throughout the description and drawing.
