Abstract

The finding concerns a structure for continuous linear luminous openings made on ceilings and walls, in particular of the built-in type, where the support structure (100) is inserted onto a gap (K), defined by plasterboard sheets (C), which have a coating function, such as wall linings and/or false ceilings. In particular such a structure is made up of a first element consisting of a shaped structural profile (1), which contains the light source (W). Such a structure is in particular characterised in that the shaped profile (1) is made up of a longitudinal box-shaped body (3), open on the lower side, from which fingers (4) extend at the top, to increase the efficiency in the subtraction of heat.

Description

The present finding concerns a structure for continuous linear luminous openings made on ceilings and walls, according to the general part of claim 1.
Among the various "lighting points" present in civil lighting systems, there are well-known so-called "built-in spotlights", thus defined since they are inserted in a support structure, which consists, in most cases, of plasterboard sheets, which have a coating function, such as wall linings and/or false ceilings.
Recently, as well as the well-known and common single spotlights, applied built into the ceiling or wall, so as to obtain concentrated and distanced lighting points, spotlights are also used to obtain continuous linear luminous openings.
Constructively, such a new type of "linear spotlight" consists of a shaped structural profile extending longitudinally that is inserted in the gap through a longitudinal slit made on the plasterboard wall and held through screws that screw from the outside onto tabs with which the aforementioned profile is equipped, so as to go into abutment against the inner part of said wall.
After having equipped the profile with the light bulbs (led strip, halogen, fluorescents T5 or of another type) the longitudinal slit is closed from the outside with the application of a transparent, semi-transparent or opaque cover, with the function of diffusing light and of shielding the aforementioned light source from dust, humidity and insects.
In the current state of the art, the linear spotlights present on the market have the drawback that the operations of filling, shaving, finishing and painting necessary to match the structure of the profile to the outer surface of the plasterboard part are complicated and do not always have an aesthetically pleasing visual impact (for example there is the unappealing "break line", visible on the outside, which is often generated in the contact area between the edge of the plasterboard and the profile). Again in the state of the art, other drawbacks the occur in the use of linear spotlights on the market consist of the difficulty of quickly getting rid of the heat produced by the light source, the not always stable fastening of the covering mask on the profile and in that the structure is functional for a single and very precise thickness of the wall where it is applied.
Moreover, the screwing operation, which theoretically appears very simple, in practice is complex and is not always successful since the projecting inner tab of the profile has a low thickness, for which reason it can bend, or is not very long, for which reason it is difficult for the operator to identify while working from outside of the wall; all of this makes it problematic if not impossible to fasten the screw in a regular manner.
The purpose of the present finding is to make a structure for continuous linear luminous openings present on ceilings and walls, in particular made from plasterboard, which does not have the drawbacks of similar known products.
Such a purpose is accomplished by making a structure for linear luminous openings consisting of suitably shaped profile, so as to have large heat dispersion surfaces on top, strong and large side tabs for the entire longitudinal extension of the aforementioned profile and recesses at the bottom in which the underlying shaped cover locks, through a clip fastening, said shaped cover being sufficiently large so that, when it faces the wall, it covers the wall/profile contact line and thus makes the shaving and finishing operations no longer necessary in said area.
The characteristics of the finding, according to the aforementioned purposes, can be clearly seen from the content of the claims below and the advantages will become clearer from the following detailed description, carried out with reference to the attached drawings, which represent purely a non-limiting example embodiment thereof, in which:

fig.1 (table I) represents a perspective view of a wall with a gap equipped with the structure according to the finding;
figs. 2, 3 (table II) represent front section views, respectively, of the inner structural profile and of the outer cover;
fig. 4 (table II) represents the mounting step of the structure according to fig. 1;
figs. 5, 6 (table IV) represent elevated views of the structure applied onto two walls of different thickness;
fig. 7 (table V) represents an exploded perspective view of the components of the structure according to fig.1.
fig. 8 represents a front outer view of a wall equipped with the structure according to the finding.

As can be seen in fig. 1, the structure for linear luminous openings, indicated with reference numeral 100, which contains the light source "W", is applied onto a wall "C", normally made from plasterboard, which defines a gap "K".
As can be seen in figs. 2, 3 the structure 100 consists of a shaped profile extending longitudinally, indicated with reference numeral 1, fixed onto the inner part of the inner wall "C", astride of a corresponding longitudinal slit "F" and a transparent, semi-transparent or opaque cover extending longitudinally, indicated with reference numeral 2, positioned in contact with the outer part of the aforementioned wall "C" and removably fastened on the aforementioned profile, all as per sé known.
As can be seen in fig. 2, the shaped profile 1 is made up of a longitudinal box-shaped body 3, open on the lower side, from which fingers 4 extend at the top, to increase the efficiency of heat subtraction, laterally of two opposite tabs 5, to allow the body to rest on the wall "C" and at the bottom of two opposite anchors 6, spaced apart from one another (by a value "L") so as to insert until they abut against the two corresponding sides of the slit "F" and each equipped, in their inner part, with one or more recesses 7. As can be seen in fig. 3, the cover 2 consists of a longitudinal base 8, from which two opposite longitudinal ratchets 9 rise up perpendicularly, each equipped at the upper end with a boss 10 and from the two sides two longitudinal strips 11 extend in line, so that the total transversal width "X" of the base is greater than the width of the slit "F" made on the wall "C".
Operatively, firstly the shaped longitudinal profile 1 is inserted, through the longitudinal slit "F" made on the wall "C" and it is locked against the aforementioned wall through the screwing from the outside of the screws "V" that hold the tabs 5 (see fig. 4).
Thereafter, the cover 2 is applied, bringing the two ratchets 9 into engagement with elastic "clip-type" engagement on the two corresponding anchors 6.
In practice, as can be seen from figs. 5 and 6, the cover 2 can be applied in two different positions, by simply taking the bosses 10 to insert into the upper recesses 7.1 or into the lower recesses 7.2, so as to be able to use the same structure 100 with two different thicknesses "S₁" and "S₂" of the wall "C".
As can be seen in figs. 2 and 7, the longitudinal box-shaped body 3, is completed with two side eyelets 12, which have the function of allowing the screws 14 to be screwed in, which hold the plate 13, for the head closure and with the channel 15, to allow the locking of the lamina 16, which holds two consecutive bodies 1.1 and 1.2.
Constructively, the profile 1 is made from extruded aluminium profile, whereas the cover 2 is made by extrusion of plastic material of a single type or of two different types, where the two ends are made from opaque polycarbonate, whereas the central part 17 of the base 8 is made from transparent, semi-transparent or opaque polycarbonate and can have a varied configuration and can have a pleasant appearance (see fig. 8).
From what has been described above it can be seen that all of the foreseen purposes have been accomplished, in particular a substantial dispersion of the heat produced by the light source "W" thanks to the large exchange surface offered by the plurality of fingers 4, quick and secure screwing of the screws "V" thanks to the substantial width and continuity of the tabs 5 and a certain aesthetic effect, thanks to the fact that the strips 11 cover the profile line of the slit "F" on the outside.
Of course, the shape, size and materials can undergo modifications and variants, provided that it is all covered by the inventive concept expressed in the following claims.
