Question No.g) l oo,dl&wo5) Filed on Off f / (){ ***** equipment This invention concerns the sector of mounting on a electrical, and refers in particular to a system of support frame of modular electrical devices or their replacements, such as hole cover. The assembly of modular electrical devices, also called sockets electrical and hereinafter referred to as such, such as switches, pushbuttons, sockets current, emergency lights, bells, buzzers and / or other acoustic or luminous signalling devices, without hole covers, on a support frame is well known, as are the fixings of the frame that carries the electrical fruits to a box of e <lmtenimento da recessed into the wall or any surface and application to the frame of a front cover and finishing plate. ---J -- -- - T - H - -- --- --o ..-- THE BIESSE s.r.l. Typically, the support frame is equipped with a window for to accommodate, with insertion from front to back, electrical appliances and / or hole covers, placed side by side, all the same size or of the same size different, but still multiple compared to those of a modular fruit ili~. I According to a well-known technique, which is also used intensively from the same applicant, and not only, the support frame is equipped along each of two opposite sides of its flexible tongue window, in . " " . " I " " ldfl d number less corresponding to the number of electricians to mount on each one. defined by lateral notches for its flexibility. D' electric fruit, has essentially a paralJelepiped body, which contains the related electrical components and which are present on each of them two of its opposite sides have a hooking tooth. So how much each fruit is inserted into the support frame, the hooking teeth on the j:lue opposite sides of the electric fruit snap into place with the free end of corresponding flexible tabs on opposite sides of the frame, ensuring with this a stable assembly of the fruit without the possibility of its involuntary or accidental slipping. Always according to the known technique and to facilitate the driving and the centering during its insertion into the support frame, each fruit electric was also made with two guide ribs on opposite sides of the coupling tooth, parallel to the direction of insertion of the fruit and intended to fit into corresponding slots made in the frame of support from opposite sides of each flexible tab, open frontally 25 and closed towards the inside of the frame itself" - - - -- - -- - - - - - - - - ---- -- --- ,--- --- 1---- BIESSE srl . . . . . I. A l tr f occasionally, to ensure a better attachment to all electric and support frame, it was also proposed to obtain the ends of the above guide ribs a portion in the shape of a semi-dovetail which, when the electrical plug is inserted THE bottom in the support frame, it engages in a way that interlocks with the closed end of said guide slots. With QU1ta mode of assembly, in addition to the snap-fitting between the electrical socket and the frame support, thanks to the interlocking coupling of beautiful portions semi-dovetail creates a connection between the opposite sides of the frame to prevent it from spreading under stress which could also lead to a disconnection of the electrical fruit. Starting from these premises, it is an aim of the present invention to propose a coupling and hooking system between electrical fruits and . . . . .. . I lld al d relative te alO The support re Ized through a new Isposition and combination of the means that contribute to the coupling, means moreover simple and certainly effective and which do not imply substantial renovations or modifications to the usual plates or weapons and support. Another aim of the invention is to offer you a frame of support for electrical fruit containing a light source placed as a frame around the electrical fruits and visible through a plate, or a transparent part of it, applied and covering frontally the same support frame. oval with a These objectives are achieved in accordance with the system for fixing electrical devices to a support frame BIESSE srl according to claim 1; other preferred features appear from dependent claims. Further details of the invention will be readily apparent from the following the description made with reference to the 4 attached drawings, indicative and non-limiting, in which: Fig. 1 shows an exploded view of a support frame, of the front panel or cover of an electrical socket and of a cover plate; Fig. 2 shows the assembled set of Fig. 1; Fig. 3 shows the frame only with the front of the electrical outlet hooked on to you; Fig. 4 shows a cross-section along the arrows AA in Fig. 3; Fig. 5 shows an enlarged detail corresponding to the box D in Fig. 3; Fig. 6 shows an enlarged detail corresponding B circled in Fig. 4; Fig. 7 shows an enlarged detail corresponding C circled in Fig. 4; Fig. 8 shows an example of a standard electrical fruit applicable to the support frame; Fig. 8 A shows an exploded view of the fruit in support and cover plate; Figs. 9 and 10 show, respectively, an exploded view and a assembled view of another standard electrical fruit configuration applicable to the support frame; it is BIESSE s.rJ. Fig. 1 shows an exploded view of an Icon system frame. lighting and related front plate. In these drawings, a frame of support 21, of the electrical fruits, generically indicated with 22, and a front cover plate 23. The support frame 21 has a window 24 to receive side by side side by side more modular electrical fruits 22 which usually have a body box 25, represented only in Figs. 8-10, intended to contain the related electrical components and closed at the front by a 25' cover. In window 24 of the support frame, in hllOgO of the fruits modular, hole cover caps can also be attached 26 as well modular. By modular we mean not only the 22 and 24 electrical outlets correspondingly the hole cover caps 26 having, in pre-established basic size, but also the fruits, caps ~opyrophorus having a multiple dimension, for example at least double, as shown in Figs. 8-10, or fractional, for example a half, with respect to the basic module. of the frame of On each of two opposite sides of the window support 21 are made of flexible tabs 27 defined by lateral notches 27' -Fig. 5- and spaced parially in dependence on the width of the electrical components. From the sides opposite of each flexible tab 27, the support frame 21 has two guide and centering slots 28 - Figs. 3 and 7 - open towards the front and closed towards the rear of the frame itself. Each slot 28 is marked with a flared front entrance 29 dovetail - Fig. 5~e with one side BIESSE sr.t transverse terminal 30 inclined backwards, from the inside towards the exterior -Fig. 7. In turn, the lid 25' of each fruit ~2, and at the same time way each hole cover cap 26, to be mounted in the support frame 21 presents, on each of two opposite sides, a transverse dentil of hook 31 and, on opposite sides of this, two parallel guide ribs 32, extending from front to back orthogonally to the tooth opposite sides of hook 31 and intended to fit into slots 28 each flexible tab 27 of the support frame" At the end a protrusion is obtained at the front of each guide rib 32, i.e. a dovetail locking lug 33 -Figs. 1 to 5- configured like the flared mouth 29 of each slot of a portion the rear end of each guide rib 32 h cuneiform 34 with an angle similar to that of the terminal side transverse 30 of said guide slot - Fig. 7. So, when each electric fruit 22 and! or each hole cover cap 26 is coupled to the support frame 21, it is attached to it both at the level of the flexible tongue 27 which at the level of the swallow-tail projections 33. In fact, when each electrical fruit 22 or the hole cover cap 26 is inserted deeply into the window of the support frame 21, the teeth of coupling 31 from opposite sides come to engage with snap the free end of respective flexible tabs 27, as shown in the Figs. 4 and 6. At the same time, the centering ribs 32 clash with the guide slots 28 in the support frame 21 carrying the respective dovetail projections 33 to engage in interlocking, always in the . . uuu,. . .. H- H U.- ..T.. U. BIESSE srl direction of insertion of the fruit or the hole-covering cap 26, with the sides of said slots at the level of the front entrance 129, likewise to swallowtail, and their posterior cuneiform portion 34 ad engage with the inclined terminal side 30 of the steJe slots. And this THE resulting in an efficient fixing that can counteract any spreading of the opposite sides of the support frame. When a fruit has a box-like body 125 for example of double module as in Figs. 8-10, it can contain two modular devices that are the same or even different and correspondingly there two frontal strips or covers can be applied and attached 125' -Figs. 8- 8A, side by side, equal or different, compatibly with the kind of devices in said body, and each ProVVist~ of means 31-33, as described above, for its attachment also to the frame of support 21. Or the cor~o 125 of dOP~iO module can be attached a single 125" double cover as shown in Figs. 9 and 10, also equipped with means for its attachment to the frame of support 21. Or, a box body can be inserted into the said body electrical device corresponding to a single mol:ful, leaving empty the remaining internal volume of the body, and then the body will be able to be applied, side by side, a cover or front panel in association with the electrical device and a 1 hole cover cap in corresponding to its empty internal volume. ] The modular attachment system described above therefore offers a double modularity: a first modularity for the POSSIBLENESS of associating and attach to the support frame 21 Txiulari 25 electrical sockets and / or BIESSE srl hole cover caps 26 equal or different in the module (yes double), in the ej function or in the frontal drawing;1 a second modularity in the choice of single or double-module electrical devices double to be housed in the 125 box body, when this is at least double module, with the possibility of combining it with a 125mm body at least two single 125' covers or trims, identical or multiple, or a single 125" double lid, or even a lid hole covers, which can still be attached to the support frame. According to another aspect of the invention - Fig. 11, the support frame 21 presents frontally, around the fruit receiving window 24 electric 22 ej or plugs or hole covers 26, a groove ~5 to which is associated with a frame 36 carrying the lighting elements, such as LEDs or other components, capable of constituting a luminous signal continuous or discontinuous trend, visible through a frame transparent 37, applied or forming a single integrated whole with the plate 23 of front covering and finishing.
