Abstract

Structured covering frame for built-in appliances of electrical installations, which is composed of modular units, in which one of the modular units is a support bracket (1), on which a design plate (2) of variable thickness is placed, and in which a clamping ring (6) holds the modular units (1, 2, 6) attached to each other forming a covering frame, pivots (7) being introduced into the clamping ring (6) through housings (10) of the support support (1), and the end of each of the pivots having a deformation (11), with which the whole of the structured covering frame is held together.

Description

Structured covering frame for devices recessed electrical installations.

The invention relates to a framework of structured coating for built-in appliances electrical installations, according to the preamble of claim one.

Coatings of this class already known, which used as single frames or multiple frames for such devices such as switches, plug boxes, signals lights, indication units, lamps, dimmers luminosity of lamps, communication devices, as well as apparatus of the building systems technique and the like are so far composed of several individual pieces, which must be assembled by the client or by the installer when performing the installation on the wall or in cable channels and the like. Generally, the installer receives the corresponding device basic recessed together with the support ring, which has to be fasten by means of claws or screws for boxes in the box already recessed for placement of the devices or in the cable channel. Next, the installer places a support on top of the box of support and a design plate (usually of glass), introduces in a hole cut in the plates the corresponding piece central or accessory of the operating element and then fix these individual parts in the basic device embedded with the means mechanics provided and supplied by the manufacturer of the device. A difficulty in assembling this relatively large number of individual pieces is that the various pieces have to be held in position on a vertical wall until its final clamping by means of the mechanical clamping element by part of the client or the installer, avoiding being Move from your site.

The design plates mentioned above are manufactured or cut to size as a rule from sheet material (plastic, metal, glass, clay, combined materials or similar) for reasons of configuration esthetic.

The support brackets are adapted to the design plates in terms of material technique. As a rule They are generally made of insulating material (almost always plastic or cardboard) and placed between the support ring of the apparatus and design plate, for insulation purposes. When use glass design plates, support brackets prevent also the vision through them towards the basic apparatus recessed

Since design plates almost always alone they can be manufactured with relatively large tolerances in as for its thickness, due to the manufacturing process for the material of the design plates, until now the Mounting procedure mentioned above to compensate for these tolerances

Therefore, the object of the present invention is to create a suitable support for covering frames structured and for lasting bonding, taking into account a Variable thickness of a design plate.

According to the present invention, this is achieved by means of the characteristics indicated in claim 1. Other embodiments of the invention are indicated in the characteristics of the dependent claims.

The following describes and explains more. the invention in detail by means of an exemplary embodiment. The attached drawings show:

-

in figure 1, in perspective, an installation arrangement made according to the state of the art;

-

in figure 2 in perspective the individual parts of the covering frame proposed in the present invention;

-

in figure 3 in perspective an installation arrangement with the framework of coating made according to the invention;

-

in figure 4 in perspective the covering frame made according to the invention and according to figure 3, in its assembled state, seen in perspective;

-

in figure 5 a sectional representation according to figure 4 by the cut line B-B, as well as a detail Y in size extended.

A sequence is represented in figure 1 conventional assembly of a recessed device installation with a corresponding covering frame. The basic device recessed 5 is mounted in an installation box or in a box of a  cable channel, not shown in the drawing. Then you place both the support bracket 1 and the design plate 2 on a support ring of the recessed basic apparatus 5 and are held by the installer in their corresponding position. Finally, the central part 3 is introduced, for example a base of plug, through the holes 9 of the support bracket 1 and of the design plate 2 and is fastened by means of a screw 4.

Figure 2 shows the configuration made according to the invention of a structured covering frame, which It consists of modular units. A modular unit is the support of support 1, on which a design plate 2 is placed. The second Modular unit, configured as a design board, can have a variable thickness The third modular unit is configured as clamping ring 6, which is provided with pivots 7. When fitted each other modular units 1, 2 and 6, forming a frame of coating, the pivots 7 are introduced through housings 10 located on the support bracket 1. The ends of the pivots 7, which protrude outside the support bracket 1, have a deformation 11, with which the coating frame.

Figure 3 shows the assembly sequence of a recessed appliance installation with the covering frame composed of modular units 1, 2 and 6. Here you can see the mode in which the built-in basic device 5 must be mounted in a recessed box or in a cable channel installation box, not explicitly represented here. Then the covering frame on the device support ring recessed basic 5 and the corresponding center piece is introduced 3 through hole 9 of the cover frame, holding it by means of a screw 4.

Figure 4 shows the assembled assembly already described in figure 3. Finally, figure 5 shows a section representation by cutting line B-B of figure 4. For the detail Y, enlarged with respect to said section,  you can see in a special way the way they fit between yes the modular units 1, 2 and 6 to form a frame of coating and hold together in a durable way by deformations 11 made at the ends of the pivots below the support bracket 1.
