DESCRIPTION

of the PATENT FOR THE INDUSTRIAL MODEL OF

UTILITY'

having as title:

? MODULAR COMPOSITE PLATE FOR

BUILT-IN ELECTRICAL APPLIANCES "

STATE OF THE TECHNIQUE

This utility model? refers to electrical control, signaling and safety devices, and concerns more? in particular a modular recessed plate.

Purpose of the finding? to provide a plate for particularly built-in electrical appliances suitably connected to a reinforcing metal frame, said plate / frame assembly being able to be snap-connected with other plates in order to obtain functional modules.

AND? known the use of plates designed to accommodate more? electrical appliances such as switches, sockets, control and / or signaling devices.

However, the ways of connecting more? plates for their subsequent housing in flush-mounted boxes frequently presents problems for their correct alignment, there? leading to the fact that they can sometimes occur in incorrect positions when fastening in the flush-mounted box.

Another problem? that relating to the sturdiness of the plates at the time of fixing itself, which normally takes place by means of screws.

PURPOSE AND OBJECT OF THE MODEL

Purpose of the present invention? that of obviating the aforementioned drawbacks through the adoption of a composite and modular plate whose structure and functioning will be in any case more? evident with reference to the accompanying indicative and non-limiting drawings in which: Fig. 1 shows, seen from below, the metal frame of the plate under examination;

Fig.2 shows, in perspective view, the support for housing the electrical appliances;

Fig.3 shows in perspective from below, the frame and the support coupled;

Fig.4 shows in section, according to the arrows A-A of Fig.3, the coupled frame and support;

Fig.S shows coupled frame and support seen in plan from below;

Fig.6 shows in detail the modular connection between plates; And

Figures 7, 7a and 7b schematically show some decomposability solutions. of the plaque under examination.

In that drawing, with 1? a substantially rectangular metal frame is indicated.

Said frame? consisting of two flat portions of ends? 2 provided with orthogonal reinforcement plates 3, said plates having slots 4.

The flat portion 2 extends along the long sides of the frame, defining a plurality of elements. d? recesses 5 and teeth 6. In correspondence to said long sides of the frame there are also two fins 7 orthogonal to the flat portions 2 provided with openings 8.

The flat portion 2 with the part provided with the recesses S and the teeth 6 defines a window F intended to receive a support 9 complementary thereto. According to the invention, said support 9? consisting of a box-shaped element in plastic material having an upper flat area 10 defining a frame and provided on the short sides 11 with slots 12 coinciding with corresponding slots 13 provided on the frame 1 for fixing the plate in place.

The support 9 also has side walls 14 provided with a plurality of elements. of slots 15 inside which elastic tabs 16 are provided for snap fastening of fruits, such as switches and other electrical devices (not shown).

Said side walls 14 are mutually connected by two other walls 17 on each of which? provided a pair of elastic tabs 18.

In accordance with the invention, first connection means 19 and second connection means 20 are formed on the side walls 14 and are intended to be combined with similar means provided on other plates (Fig. 6).

The plate in question is therefore composed of a metal bearing frame 1 intended to accommodate a support 9 made of plastic material, said support 9 being snap-connected to the frame 1 at least by means of the elastic tabs 18 cooperating with the slots 4 present on the plates 3. The connection, still elastic, of the means 19 and 20 with complementary similar means provided on adjacent supports, furthermore allows to achieve exact slowing-down between the plural elements. plates (Figs. 7, 7a and 7b).

Claims (4)

R I V E N D C A Z O N I 1. Composite modular plate for built-in electrical appliances comprising a metal frame (1) designed to snap together with a support (9) made of plastic material, said support having a plurality of elements. of slots (1S) for snap hooking of electrical appliances. 2. Composite modular plate as per the preceding claim, characterized in that the support (9) has at least two elastic tabs (18) intended to snap through corresponding openings (15) provided on a plate (3) reinforcing the frame (1 ). 3. Modular plate as per the preceding claims, characterized by the fact that the support (9) provides elastic coupling means (19, 20) for the aligned connection of several elements. plaques 4. Composite modular plate for built-in electrical appliances, as substantially described above, illustrated and claimed for the specified purposes.
