Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Other features and advantages of the present disclosure will become apparent from the following detailed description of the present disclosure with reference to the accompanying the FIGURE, in which:

[0023] FIG. 1 shows a frame section according to the present disclosure for producing a backlit false wall.

DETAILED DESCRIPTION

[0024] In relation to the single the FIGURE, there is described an example of a frame section 1 intended to constitute, with similar frame sections, a frame on which one or two stretched flexible canvas(es) can be fastened to create a backlit false wall.

[0025] To facilitate the description, the frame section 1 will be described with respect to its position illustrated in the FIGURE.

[0026] The frame section 1 comprises a tubular section body having a peripheral wall 2 defining a first and a second lateral face 20, 21 that are connected to each other by an upper face 22 and a lower face 23. In the embodiment shown, the upper and lower faces 22, 23 are substantially flat, while the first lateral face 20 is rounded. In the example shown, the radius of curvature of the first lateral face 20 is identical to the width of the section body, which in turn is identical to the height of the section body.

[0027] The section body comprises a first cavity 3 extending over the entire length of the body and having an opening on the first lateral face 20. The first cavity 3, advantageously of parallelepipedal section, forms a cavity for attaching stretched canvas.

[0028] In the illustrated embodiment, it is arranged to allow the attachment of two stretched canvases. To do this, it comprises an inner wing 5 extending from the bottom of the first cavity 3 toward the opening of the cavity, so as to define, within the first cavity 3, two symmetrical housings 30, 31 allowing the respective attachment of a canvas. The attachment of the canvases on the frame section 1 is carried out by means of shoulders 6, 7, 8 advantageously arranged on each face of the inner wing 5 as well as on the inner faces of the upper and lower walls of the section body. These shoulders 6, 7, 8 are arranged to allow the attachment of attachment means, of the harpoon type, provided at the edge of the canvas.

[0029] The section body comprises a second cavity 4 extending over the entire length of the body and having an opening 40 on the second lateral face 21. The first and second cavities 3, 4 thus open in a direction opposite one another.

[0030] The second cavity 4 forms a lighting means receiving cavity 9. It has an end wall 41 bordered by two diverging cavity walls 42, 43. The two cavity walls 42, 43 delimit, with the upper and lower faces 22, 23, the opening 40. The cavity walls 42, 43 thus define, with the upper and lower faces 22, 23, two peripheral wings of triangular section. In the illustrated embodiment, the second cavity 4 has a trapezoidal shape, advantageously isosceles. Advantageously, the cavity walls 42, 43 inclined relative to the end wall 41 at an angle of inclination α between 110 degrees and 130 degrees. Such an arrangement of the frame section makes it possible to minimize the residual peripheral shadows created by the section when it is used in a backlit context.

[0031] According to an advantageous configuration, the end wall 41 is located at a distance from the opening less than or equal to half the distance separating the ends of the upper and lower faces 22, 23 that delimit the opening 40. More generally, the second cavity 4 will be arranged to present a ratio between the height (h.sub.1) of the end wall 41 and the height (h.sub.2) of the opening 40 of the second cavity 4 between 0.4 and 0.5 (h.sub.2 corresponding to the distance separating the ends of the upper and lower faces 22, 23). Similarly, it will be advantageous to arrange the second cavity 4 so that the latter presents a ratio between the depth (p) of the end wall 41 and the height (h.sub.2) of the opening of the second cavity between 0.3 and 0.4. Such an arrangement of the frame section thus makes it possible to obtain optimum light diffusion while limiting the residual peripheral shadows created by the section when it is used in a backlit context.

[0032] The present disclosure is described in the foregoing by way of example. It is understood that a person skilled in the art is in a position to produce various variant embodiments of the present disclosure without thereby departing from the scope of the invention as defined by the claims.
