Definitions

• the present invention relates to a luminous lambrequin for a roller blind, in particular an external blind placed on the front of a store or other establishment open to the public.
• a lambrequin is, traditionally, a strip of canvas suspended in front of a blind, under the load bar.
• the lambrequin often serves as a support for an inscription which is in particular the sign of the store, or even for example the name of a restaurant.
• a luminous lambrequin which allows to illuminate and enhance the sign, especially at night.
• a luminous lambrequin also provides lighting for the space located under the blind, when the latter is deployed; it is thus possible, in particular, to light a display case for the exterior.
• the production of a luminous lambrequin poses a certain number of technical problems.
• the lambrequin must be designed so as to illuminate both forward (sign lighting) and rear (lighting directed towards the window).
• the device must also be made in such a way as to allow easy replacement of faulty electric lamps or fluorescent tubes.
• these must be able to equip not only new blinds, but also pre-existing blinds.
• the present invention aims to solve all these problems, by providing an adequate structure for a luminous lambrequin and its means of attachment to the remainder of a roller blind.
• the subject of the invention is essentially a luminous lambrequin for a roller blind which comprises, in combination: a rigid frame composed of an upper horizontal element, a lower horizontal element and vertical elements which connect the upper element to the lower element, the upper element being provided with means for attaching to the load bar of the fabric of a roller blind, or itself constituting this load bar;
• - a translucent canvas, folded in a "U” or “V” shape, which starts from the upper horizontal element, passes under the lower horizontal element and returns to the upper horizontal element, thus forming a canvas panel front and a rear canvas panel, removable fixing means being provided between the respective upper edges of the front and rear canvas panels, on the one hand, and the upper element of the frame, on the other hand; - Electric lighting means, carried by said frame and arranged between the front canvas panel and the rear canvas panel.
• a luminous lambrequin is thus obtained, the structure of which comprises a rigid framework, a translucent canvas fixed and stretched on the framework, and interior lighting, capable of illuminating both the front face and the rear face of the translucent canvas folded in " U “or” V ".
• the upper element of the framework is a profile which comprises a horizontal core and two opposite vertical wings, respectively outer and inner, directed downwards, the core of the profile being provided means for attaching to the load bar of the fabric of the roller blind, while at the two wings are detachably fixed the respective upper edges canvas panels front and back of the translucent canvas.
• the upper edges of the front and rear fabric panels of the translucent fabric can be removably attached to the outer and inner wings of the upper frame profile by various suitable means: hook-and-loop tapes, or buttons, or even connections by grooves and beads complementary.
• the means of attachment of the luminous lambrequin to the load bar of the fabric of the roller blind consist of an attachment profile, in the form of a flat rod having continuous beads on its two longitudinal edges, one of the beads being introduced into a longitudinal groove of the load bar, while the other bead is introduced into a longitudinal groove formed on the core of the upper profile of the framework of the luminous lambrequin.
• This solution is more particularly advantageous for a luminous lambrequin to be fixed on a pre-existing blind, knowing that in the case of a new blind, the luminous lambrequin can be directly incorporated into the blind, the upper element of the lambrequin's framework then being confused with the load bar.
• the lower horizontal element of the framework, under which this fabric passes is shaped as a horizontal reinforcing plate.
• the lower horizontal element of the framework, under which this fabric passes is rather shaped as a bar.
• the electrical lighting means constituted for example by fluorescent tubes
• these can be carried by the upper horizontal element and / or by the lower horizontal element of the framework of the luminous lambrequin.
• the lighting means are thus fixed in the upper part, or in the lower part, or even in upper part and lower part. In all cases, these lighting means remain accessible, thanks to the removable fixing of the translucent fabric, which allows in particular their replacement if necessary.
• the invention will in any case be better understood with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of examples, some embodiments of this luminous lambrequin for roller blinds:
• Figure 1 is a view of the assembly, in perspective, of a roller blind equipped with a luminous lambrequin according to the present invention;
• Figure 2 is a front view, partly in section, of the luminous lambrequin alone;
• Figure 3 is a cross-sectional view of this luminous lambrequin, on an enlarged scale, along III-III of Figure 1;
• Figure 4 is a sectional view similar to Figure 3, illustrating a variant of this luminous lambrequin.
• Figure 1 shows a roller blind, designated as a whole by the reference 1, installed on the front or front 2 of a store or other room open to the public.
• the roller blind 1 comprises a fabric 3, the rear end of which is linked to a winding tube 4 mounted rotating in bearings 5 fixed against the facade or storefront 2, and the front end of which is linked to a load bar 6.
• the latter is held by means of articulated tension arms 7.
• the lambrequin generally designated by the reference 8 is attached under the load bar 6.
• the structure of the lambrequin 8 is described below in a first embodiment, also referring to FIGS. 2 and 3.
• This structure comprises a rigid framework, which itself consists of an upper horizontal profile 9, a lower horizontal reinforcing plate 10, and uprights 11 which connect the upper section 9 to the lower plate 10.
• the upper section 9 has a horizontal core 12, and two opposite vertical wings 13 and 14, respectively outside and inside, directed downwards.
• the lambrequin 8 also has a translucent fabric 15, folded in a "U" shape, which forms a front fabric panel 16 and a rear fabric panel 17, which are substantially parallel.
• the front canvas panel 16 extends from the lower plate 10 to the upper profile 9; the upper edge of this front canvas panel 16 is detachably fixed, in particular by means of hook-and-loop tapes 18, on the outer wing 13 of the upper profile 9.
• Symmetrically, the rear canvas panel 17 extends from the lower plate 10 to the upper profile 9; the upper edge of this rear canvas panel 17 is detachably fixed, in particular by means of hook-and-loop tapes 19, on the inner wing 14 of the upper profile 9.
• the lower part of the translucent fabric 15, which connects its front panel 16 at its rear panel 17, passes under the lower plate 10 of the frame.
• the assembly of the luminous lambrequin 8, thus formed, is suspended under the load bar 6 of the fabric 3 of the roller blind 1 by means of an attachment profile 22, in the form of a flat rod, but having continuous beads, respectively 23 and 24, on its two longitudinal edges.
• One of the beads 23 is introduced into a longitudinal groove of the load bar 6.
• the other bead 24 is introduced into a another longitudinal groove formed on the upper face of the core 12 of the upper section 9 of the lambrequin frame 8.
• the lighting means 20 and / or 21 make it possible to light, from the inside, the two canvas panels 16 and 17, stretched between the base and the top of the lambrequin 8.
• the lighting of the canvas panel before 16 makes it possible to bring out inscriptions 25, such as a sign, carried by this canvas panel 16.
• the electrical supply of the lighting means 20 and / or 21, incorporated in the lambrequin 8 is easily achievable by passing the electrical conductors in or on one of the tension arms 7 of the blind 1.
• the hook-and-loop tapes 18 and 19 allow, if necessary, access to the interior of the lambrequin 8 for replacement of a defective fluorescent tube 20 or 21, or even to replace the entire fabric 15, if it is worn or deteriorated, or even in the event of a change of sign.
• Figure 4 in which the elements corresponding to those described above are designated by the same reference numerals, represent a variant in which the fabric 15 of the lambrequin 8 is no longer shaped as "U”, but in "V", the lower plate the frame being here replaced by a lower horizontal bar 26, narrower, under which passes the fabric 15. The bar 26 can still support fluorescent tubes 21.
• Figure 4 also indicates other means of removable fixing of the two panels of canvas 16 and 17 of the upper profile 9, these means here comprising longitudinal grooves formed in said wings 13 and 14, and receiving the upper edges, provided with respective beads 27 and 28, of the two canvas panels 16 and 17.
• the latter means are also applicable in the case of a fabric 15 folded in a "U" shape.
• the connection between the luminous lambrequin 8 of FIG. 4 and the load bar 6 is also carried out by means of an attachment profile 22, similar to that of FIG. 3.
• the load bar 6 usually comprises a longitudinal groove for the suspension of a lambrequin, it is understood that the luminous lambrequin 8, object of the invention, can be easily mounted on a pre-existing blind 1.
• buttons By the use of any means of removable fixing of the translucent fabric of the frame, a system of buttons which can in particular be envisaged;
