Application to flush fitting lamps in false ceilings.

Description

'' DEVICE FOR RECESSING A LUMINAIRE IN A FALSE PLA-
WTD, TO BE ASSEMBLED BY LOCKING CALIPER '.

 The present invention relates to a device for casting a light fixture in a false ceiling, comprising a collar and a socket holder bracket.

 The invention finds a particular advantageous advantage in the field of construction, logistics and the finishing of recessed luminaires of false ceilings for reflector lamps.

 The usual production of such devices produced in large quantities uses the presence of a generally metallic flange, the outside diameter of which masks the cut-out in the false ceiling. The inside diameter receives the bulb of the drupe. When making the flange, the inner metal flank is lost.

 The currently known embedding devices which are comfortable in the preamble have a socket-holder stirrup, the legs of which are, for example, spot welded at their end on the inside diameter of the flange, then the entire stirrup flange is lacquered. However, these known embedding devices have a certain number of drawbacks. In particular, they do not allow a change of finish (color of the collar) or of the height of the stirrup during production or possibly on the site.

 Also, the technical problem to be solved by the object of the present invention is to propose a device for embedding a luminaire in a false ceiling, comprising a collar and a socket-holder bracket, which would offer greater flexibility of production and use.

 your solution to the technical problem posed consists, according to the present invention, in that said flange has means for receiving the legs of said bracket caliper as well as first fixing means, arranged in said receiving means, and cooperating with second means of fixing arranged at the ends of the legs of said stirrup.

 Thus, .the embedding device according to the invention is presented in two separate parts, collar and socket holder stirrup, removable if necessary and therefore interchangeable, which makes it possible, for example, to choose, for a given collar, the '' stirrup whose height X is adapted to the false ceiling considered. Likewise, it is possible, whenever desired, to change the color of the collar without having to dismantle the entire embedding device.

 The invention also has other advantages such as the possibility of storing and delivering flat the dismantled collar and stirrup, which represents a much smaller volume than that occupied by the embedding device known from state of the art where the stirrup is permanently fixed to the flange, from manufacture.

 In a particular embodiment of the invention, it is provided that said means for receiving the tabs of the socket-holder stirrup are constituted by doublerabats produced by cutting and bending the internal diameter of the collar.

 This advantageous arrangement leads to an economy of internal material by producing the double-flaps in the material of the internal metal flank of the collar intended to be lost.

 The description which follows with reference to the appended drawing, given by way of nonlimiting example, will make it clear what the invention consists of and how it can be implemented.

 Figure t is a perspective view of a mounting device according to the invention.

Figure t shows, in perspective, a device for embedding a luminaire in a false ceiling, comprising a flange 10 and a bracket 20 socket holder. Like the iodic in FIG. 1, said collar 10 has means
it de-réceptòfl legs 21 of said stirrup 20. In the embodiment given in Figure 1, these means 11 for receiving
consist of double-flaps made by cutting and bending the inside diameter of the collar, a part generally lost in traditional construction. In this way, the stirrup 20 is brought into position on the flange by simple pushing of the lugs 21 inside the double-råbats 11. Next, the first fixing means 12, 13, arranged in the means il receiving the flange, cooperate with second fixing means 22, 23 arranged at the ends of the lugs 21 of said stirrup 20 in accordance with the embodiment of FIG. 1, the first fixing means consist of perforations 12 and protrusions 13, while the second fixing means consist, respectively, of protrusions 22 and perforations 23.
