For the installation of several electrical installation devices Various arrangements have already become known in a single flush-mounted box. These consist of a common plate built into the box for all installation devices or from a frame in which the installation devices are hung, or from webs that are arranged on both sides of the installation apparatus and to which these are attached. The usage such webs has also become known for connecting several plumbing devices via plaster. These known support members each have to be attached to the housings of the cans with special screws be attached.

The invention now relates to such a flush-mounted box for several electrical installation devices with a common cover held by screws, with over the edge of the. Can stepping and supporting members for the installation apparatus, with the. Supporting organs perpendicular to the bottom of the box several parallel to the connecting line of the installation apparatus Flaps are angled, the ends of which are parallel to the bottom of the can towards the inside of the can are turned.

The invention consists in that a part of the ends in a known manner for holding the installation equipment, the other part to support known ones. Spreading to attach the Support members in the box are used and that posts of two types are arranged on the bottom of the box so that on the one hand the installation equipment is guided and the other on guiding the screws for the spreading, and that by engaging in the Installatiotisapparate screws for the Cover the plumbing devices are pressed against the ends from below.

The flush box according to the invention has the advantage over the known boxes that each Flush-mounted box two screws less are required because the cover fastening screws are used at the same time serve to fasten the installation equipment. In addition, it also has the further advantage of that it is possible to attach the Tragörgane with the known simple spreaders in the box. The support members are expediently made up of two rails in a manner known per se, wherein by connecting the rails by crossbars, the support members take the form of a known support frame Form, with tabs also arranged for the support frame fastenings on the crossbars are. The tabs for the rail attachment are useful between the tabs for the Apparatus fastening arranged. In the ends are flush-mounted boxes for several electrical ones Installation apparatus

Nut thread intended for the expansion screws. Tongues for guiding the support members in grooves in the can can be provided on the tabs. Finally, it is advisable to design the posts as metal pins. _r .. ■ .. '; ■

The flush box according to the invention is. in the Drawing shown in several illustrations.

Fig. 4 shows a support frame alone;

Fig. 5 shows a section of the guide of the spreading screws and shortened post or Flap arrangement.

On the flush-mounted box 1, which accommodates several installation devices, the support members 2 and 3, designed as rails, for holding the installation devices 4 are attached to the two longitudinal walls, namely on top of the edges. The rails are kept wide enough so that they provide ample plaster compensation. Several tabs 2 a, 3 a and 2b, 3b, which are used to hold the installation apparatus 4 and the support elements themselves, extend downward from the support members. The flaps 2 a, 3 a are in a known manner at their lower ends 2d, 3d and again angled in parallel to the bottom of the can, to the interior of the can, where they then interfere with the installation apparatus. 4 They lie there loosely in the base.

In addition to the tabs 2 a, 3 a , the plumbing equipment is still loosely in the post 5 of the socket

The installation apparatus can also have different dimensions in height due to the deactivation of the guide on the post. ίο devices intervene and ... tighten them from below against the ends 2 d, 3 d. ■ ■ For the; Fastening, the support members 2 and 3, are provided by the pips * 2'5'urid 3 & ". They are located in the gaps between the other tabs 2 a and 3 a serving for the installation apparatus. The posts 5 a" are used for Guide the expansion screws 6 a, which engage in the thread-bearing ends 2e and Ze. The spreaders 6 are guided in the usual way in slots of the tabs 2 b, 3 b. The devices for the additional, but optionally to be used, known screw fastenings for the support members 2, 3 are arranged at the same points at the top in the edges of the support members which have recesses 8 for the shafts of the screws 7. In another embodiment of the support elements are, - as .. from Fig ,; 4 can be seen, the two support members 2 and 3, which are designed as rails, are connected to one another by transverse webs 9, so that a support frame is formed. The support frame is now attached by means of two spreaders which are attached to the transverse webs 9 and the tabs 9 a. To the side of the tabs 9 a or the associated post, there is enough space for the introduction of the connecting cables into the box. The rails 2 and 3 as well as the frame also have tongues 2 c and 3 c / which are bent in grooves 1 a · of the housing 1 by the tabs 2 α and 3 α. This guide is used to secure the supporting elements against the side. Move. '; -'; '· ".'" "■■ _ ■ i; Claims: 1.'
