Description

La présente invention concerne les présentoir, notamment les présentoirs pour vitrines de magasins.The present invention relates to the display stand, in particular the display cases for shop windows.

Il est connu de réaliser des présentoirs portant sur leur face avant un logo, une marque, ou tout autre signe distinctif. De tels présentoirs sont généralement disposés dans les vitrines de magasins et accompagnent des produits divers tels que des montres, des bijoux, des vêtements, afin d'indiquer l'origine de ces produits.It is known to make displays on their front face a logo, a mark, or any other distinctive sign. Such displays are generally arranged in shop windows and accompany various products such as watches, jewelry, clothing, to indicate the origin of these products.

La présente invention se fonde initialement sur l'idée de réaliser un présentoir rétroéclairé comprenant une plaque frontale opaque présentant une ou plusieurs zones transparentes à la lumière formant le signe distinctif à présenter au public, et des moyens de rétroéclairage de la plaque frontale.The present invention is based initially on the idea of producing a backlit display including an opaque front plate having one or more light-transparent areas forming the distinctive sign to be presented to the public, and backlighting means of the front plate.

Le rétroéclairage de la plaque frontale peut être assuré par une ampoule électrique. Cette solution présente toutefois divers inconvénients, tant esthétiques que pratiques, liés à la nécessité de prévoir un raccordement de l'ampoule au réseau électrique. De plus, pour des raisons de sécurité, les vitrines de magasins ne sont généralement pas équipés de prises électriques au sol et ne bénéficient que d'un éclairage vertical délivré par des projecteurs ou des spots lumineux.The backlighting of the front plate can be provided by a light bulb. This solution, however, has various disadvantages, both aesthetic and practical, related to the need to provide a connection of the bulb to the power grid. In addition, for security reasons, shop windows are generally not equipped with electrical outlets and only benefit from vertical lighting provided by spotlights or spotlights.

D'autre part, un présentoir du type discuté ici étant destiné à être utilisé plusieurs heures par jour voire en permanence, l'utilisation de piles électriques est difficilement envisageable en raison de leur médiocre longévité.On the other hand, a display of the type discussed here being intended to be used several hours per day or permanently, the use of batteries is difficult to envisage because of their poor longevity.

La présente invention vise ainsi un présentoir rétroéclairé qui soit simple d'emploi, d'un prix de revient réduit, et qui ne nécessite pas de raccordement au réseau électrique.The present invention thus provides a backlit display that is easy to use, low cost, and does not require connection to the power grid.

Le document US 5160195 décrit un dispositif d'affichage rétroéclairé comprenant un moyen d'éclairage intégré dans le dispositif et agencé à l'arrière d'une surface d'affichage à rétroéclairer. Un mode de réalisation du dispositif comprend une surface réfléchissante agencée pour renvoyer la lumière émise par le moyen d'éclairage vers la surface d'affichage à rétroéclairer.The document US 5160195 discloses a backlit display device comprising illumination means integrated into the device and arranged at the rear of a display surface to be backlit. One embodiment of the device comprises a reflective surface arranged to return the light emitted by the illumination means to the backlit display surface.

La présente invention se base sur l'observation selon laquelle les vitrines de magasins sont souvent fortement éclairées par des sources de lumière se trouvant au-dessus des zones de présentation d'objets. Comme cela a été indiqué plus haut, il s'agit généralement de projecteurs ou de spots lumineux, agencés dans les plafonds ou dans les faux-plafonds.The present invention is based on the observation that shop windows are often strongly illuminated by light sources located above object presentation areas. As mentioned above, these are generally projectors or spotlights, arranged in ceilings or false ceilings.

Ainsi, une idée de la présente invention est d'intégrer dans un présentoir du type précité un système à miroir permettant de "récupérer" la lumière verticale et la renvoyer sur la face arrière de la plaque frontale, le miroir formant une source de lumière virtuelle agencée derrière la plaque frontale.Thus, an idea of the present invention is to integrate in a display of the aforementioned type a mirror system for "recovering" the vertical light and return it to the rear face of the front plate, the mirror forming a virtual light source arranged behind the front plate.

Plus particulièrement, la présente invention prévoit un présentoir rétroéclairé, notamment pour vitrine de magasin, tel que défini par la revendication 1.More particularly, the present invention provides a backlit display, especially for shop window, as defined by claim 1.

Ces objets, caractéristiques et avantages ainsi que d'autres de la présente invention seront exposés plus en détail dans la description suivante d'un exemple de réalisation d'un présentoir rétroéclairé selon l'invention, faite à titre non limitatif en relation avec les figures jointes parmi lesquelles :

  • la figure 1 est une vue de face d'un exemple de réalisation d'un présentoir selon l'invention,
  • la figure 2 est une vue en coupe verticale du présentoir de la figure 1,
  • la figure 3 est une vue en coupe horizontale du présentoir de la figure 1,
  • la figure 4 est identique à la figure 2 et illustre le parcours de rayons lumineux dans le présentoir selon l'invention,
  • la figure 5 est une vue en coupe verticale d'une variante de réalisation d'un présentoir selon l'invention, et
  • la figure 6 est une vue en perspective d'une autre variante de réalisation d'un présentoir selon l'invention.
These and other objects, features and advantages of the present invention will be set out in more detail in the following description of an exemplary embodiment of a backlit display according to the invention, given in a nonlimiting manner in relation to the figures. attached, among which:
  • the figure 1 is a front view of an exemplary embodiment of a display according to the invention,
  • the figure 2 is a vertical sectional view of the display of the figure 1 ,
  • the figure 3 is a horizontal sectional view of the display of the figure 1 ,
  • the figure 4 is identical to the figure 2 and illustrates the path of light rays in the display according to the invention,
  • the figure 5 is a vertical sectional view of an alternative embodiment of a display according to the invention, and
  • the figure 6 is a perspective view of another alternative embodiment of a display according to the invention.

Les figures 1, 2 et 3 illustrent un exemple de réalisation d'un présentoir 10 selon l'invention. La figure 1 est une vue de face du présentoir. La figure 2 est une vue en coupe du présentoir selon un plan de coupe vertical AA' représenté en figure 1. La figure 3 est une vue en coupe du présentoir selon un plan de coupe horizontal BB' représenté en figure 1.The Figures 1, 2 and 3 illustrate an exemplary embodiment of a display unit 10 according to the invention. The figure 1 is a front view of the display. The figure 2 is a sectional view of the display unit according to a vertical sectional plane AA 'shown in FIG. figure 1 . The figure 3 is a sectional view of the display unit in a horizontal sectional plane BB 'shown in FIG. figure 1 .

Le présentoir 10 comprend une plaque frontale opaque 1 présentant au moins une zone transparente 2 formant un logo, une marque, ou tout autre signe distinctif. On trouve ici cinq zones transparentes 2 formant les cinq lettres du mot "TEXTE", choisi à titre d'exemple.The display 10 comprises an opaque front plate 1 having at least one transparent zone 2 forming a logo, a mark, or any other distinctive sign. Here we find five transparent areas 2 forming the five letters of the word "TEXT", chosen as an example.

Pour des raisons de lisibilité des figures, la représentation en noir et blanc de la plaque frontale 1 est le négatif de l'aspect réel du présentoir 10. Ainsi, les zones transparentes 2 formant les lettres du mot "TEXTE" apparaissent en noir sur les figures au lieu d'apparaître en clair, tandis que le reste de la plaque frontale l'apparaît en clair au lieu d'être de couleur foncée. Cette couleur foncée est de préférence du noir pour l'obtention d'un contraste maximal entre les zones transparentes 2 et le reste de la plaque frontale.For reasons of readability of the figures, the black and white representation of the front plate 1 is the negative of the actual appearance of the display 10. Thus, the transparent areas 2 forming the letters of the word "TEXT" appear in black on the figures instead of appearing in the clear, while the rest of the front plate appears in clear instead of being dark in color. This dark color is preferably black to obtain a maximum contrast between the transparent areas 2 and the remainder of the front plate.

La plaque frontale 1 est par exemple en verre acrylique transparent. Elle présente une face avant 1-1, une face arrière 1-2 et des bords 1-3, 1-4, 1-5, 1-6. La face arrière 1-2 et les bords 1-3, 1-4, 1-5, 1-6 sont recouverts d'une matière ou d'une peinture noire, à l'exception des zones transparentes 2. Les zones transparentes 2 peuvent être obtenues par sérigraphie ou tampographie (impression négative) ou par gravure ou retrait de la matière ou de la peinture noire après son dépôt sur la face frontale.The front plate 1 is for example transparent acrylic glass. It has a front face 1-1, a back face 1-2 and edges 1-3, 1-4, 1-5, 1-6. The rear face 1-2 and the edges 1-3, 1-4, 1-5, 1-6 are covered with a material or a black paint, with the exception of the transparent zones 2. The zones Transparencies 2 can be obtained by screen printing or pad printing (negative printing) or by etching or removing the black material or paint after it has been deposited on the front face.

La plaque frontale 1 peut toutefois être de tout autre matériau, bois, métal, verre, carton, tissu,... ou une combinaison de ces matériaux, et les zones transparentes peuvent être découpées par fraisage, laser, jet d'eau ou d'acide.The faceplate 1 may, however, be of any other material, wood, metal, glass, cardboard, fabric, ... or a combination of these materials, and the transparent areas may be cut by milling, laser, jet of water or water. 'acid.

La plaque frontale 1 est maintenue sensiblement verticale grâce à un socle destiné à être posé sur un plan horizontal. Ce socle est formé ici par un bloc support 3, en verre, verre acrylique, bois, métal, ou autre matériau. Le bloc support 3 présente une face inférieure 3-1, qui forme le socle proprement dit, et une face avant 3-2. La face avant 3-2 est orientée à 90° relativement au socle 3-1, et reçoit la face arrière 1-2 de la plaque frontale 1 (plus particulièrement la partie inférieure de la face arrière 1-2). La face arrière 1-2 de la plaque frontale 1 est fixée à la face avant 3-2 du bloc support 3 par tout moyen connu, par exemple un ruban adhésif double face.The front plate 1 is held substantially vertically by means of a base intended to be placed on a horizontal plane. This base is formed here by a support block 3, glass, acrylic glass, wood, metal, or other material. The support block 3 has a lower face 3-1, which forms the base itself, and a front face 3-2. The front face 3-2 is oriented at 90 ° relative to the base 3-1, and receives the rear face 1-2 of the front plate 1 (more particularly the lower part of the rear face 1-2). The rear face 1-2 of the front plate 1 is fixed to the front face 3-2 of the support block 3 by any known means, for example a double-sided adhesive tape.

L'angle entre la face avant 3-2 et le socle 3-1 peut également être choisi inférieur à 90°, de manière que la plaque frontale 1 soit sensiblement inclinée vers l'arrière lorsque le présentoir est posé sur un plan horizontal.The angle between the front face 3-2 and the base 3-1 can also be chosen less than 90 °, so that the faceplate 1 is substantially inclined rearwardly when the display stand is placed on a horizontal plane.

Selon l'invention, le présentoir 10 comprend un miroir 4, ici de forme rectangulaire, agencé dans un plan incliné de manière à projeter dans une direction sensiblement horizontale une lumière incidente sensiblement verticale. Ainsi, des rayons lumineux incidents arrivant sensiblement à la verticale du présentoir, sont renvoyés sur la face arrière 1-2 de la plaque frontale 1, dans une direction sensiblement parallèle à la normale N de la plaque frontale.According to the invention, the display 10 comprises a mirror 4, here of rectangular shape, arranged in an inclined plane so as to project in a substantially horizontal direction a substantially vertical incident light. Thus, incident light rays arriving substantially vertically of the display, are returned to the rear face 1-2 of the front plate 1, in a direction substantially parallel to the normal N of the front plate.

Sur la figure 4, on voit des rayons lumineux incidents L1 présentant un angle de ±α relativement à un axe vertical V. Ces rayons incidents sont transformés en rayons réfléchis L2 qui traversent la plaque frontale 1 selon un angle de ±α relativement à la normale N. L'angle α est défini ici par la demi-hauteur des zones transparentes 2, ici les lettres du mot "TEXTE", et par la distance entre le miroir 4 et la plaque frontale.On the figure 4 incident light rays L1 having an angle of ± α relative to a vertical axis V are seen. These incident rays are converted into reflected rays L2 which pass through the front plate 1 at an angle of ± α relative to the normal N. L angle α is defined here by the half height of the transparent areas 2, here the letters of the word "TEXT", and by the distance between the mirror 4 and the front plate.

Ainsi, le logo, la marque ou autre signe distinctif porté par la plaque frontale, ici le mot "TEXTE", apparaît comme fortement éclairé par l'arrière lorsque le présentoir 10 est posé sur un étal recevant un éclairage vertical intense délivré par des sources de lumière comme des projecteurs ou des spots lumineux.Thus, the logo, the mark or other distinctive sign worn by the faceplate, here the word "TEXT", appears as strongly illuminated from the rear when the display stand 10 is placed on a stall receiving an intense vertical light delivered by sources of light like spotlights or spotlights.

Dans le mode de réalisation représenté, le miroir 4 est fixé sur le bloc support 3. A cet effet, la partie supérieure du bloc support 3 est biseautée de manière à former une face inclinée 3-3 recevant le miroir 4. Cette inclinaison est de 45° relativement à l'horizontale si la plaque frontale est agencée verticalement et si la lumière à recueillir et à renvoyer sur la plaque frontale est distribuée verticalement. Il va de soi que diverses variantes de réalisation peuvent être prévues selon les conditions d'utilisation visées.In the embodiment shown, the mirror 4 is fixed on the support block 3. For this purpose, the upper part of the support block 3 is bevelled so as to form an inclined face 3-3 receiving the mirror 4. This inclination is 45 ° relative to the horizontal if the front plate is arranged vertically and if the light to be collected and returned to the front plate is distributed vertically. It goes without saying that various alternative embodiments may be provided according to the intended conditions of use.

De façon optionnelle, le présentoir 10 comprend également un bloc transparent 5 formant un guide optique, réalisé par exemple en verre acrylique. Ce bloc transparent 5 est porté par le bloc support 3 et présente à cet effet une face inférieure biseautée 5-1 qui vient s'appuyer sur la face réfléchissante du miroir 4, directement ou par l'intermédiaire d'un joint (non représenté), le miroir 4 étant ainsi pris en sandwich entre le bloc support 3 et le bloc transparent 5. Le bloc transparent présente une face supérieure 5-2, ici horizontale, qui forme un point d'entrée de la lumière, tandis que la face biseautée 5-1 forme le point de sortie de la lumière.Optionally, the display unit 10 also comprises a transparent block 5 forming an optical guide, made for example of acrylic glass. This transparent block 5 is carried by the support block 3 and has for this purpose a beveled lower face 5-1 which is supported on the reflecting face of the mirror 4, directly or via a seal (not shown) the mirror 4 is thus sandwiched between the support block 3 and the transparent block 5. The transparent block has an upper face 5-2, here horizontal, which forms a point of entry of the light, while the beveled face 5-1 forms the exit point of the light.

Optionnellement toujours, le présentoir 10 peut être équipé d'un filtre de couleur. Ce filtre est par exemple une plaquette transparente colorée 6 qui est posée sur la face supérieure 5-2 du bloc transparent, et y est maintenue par un morceau ruban adhésif. La lumière incidente passant à travers le filtre 6 avant d'être réfléchie par le miroir, les lettres du mot "TEXTE" apparaissent en couleur.Optionally still, the display 10 may be equipped with a color filter. This filter is for example a colored transparent plate 6 which is placed on the upper face 5-2 of the transparent block, and is held there by a piece of adhesive tape. The incident light passing through the filter 6 before being reflected by the mirror, the letters of the word "TEXT" appear in color.

Le bloc transparent 5 est de préférence d'une forme complémentaire à celle du bloc support 3, de sorte que l'ensemble forme un bloc d'aspect monolithique, ici un bloc de forme parallélépipédique.The transparent block 5 is preferably of a shape complementary to that of the support block 3, so that the assembly forms a block of monolithic appearance, here a block of parallelepiped shape.

Ce bloc d'aspect monolithique peut être accouplé à la plaque frontale 1 d'une manière facilement détachable, pour obtenir un présentoir modulaire pouvant de recevoir diverses plaques frontales. Ainsi, la plaque frontale 1 est par exemple fixée sur les faces avant 3-2, 5-3 des blocs 3, 5 par deux bandes adhésives double face 9-1, 9-2 (représentées en traits pointillés sur la figure 1), ce qui permet de la décoller et de la remplacer par une autre plaque frontale portant un autre signe distinctif.This block of monolithic appearance can be coupled to the front plate 1 in an easily detachable manner, to obtain a modular display can receive various front plates. Thus, the front plate 1 is for example fixed on the front faces 3-2, 5-3 of the blocks 3, 5 by two double-sided adhesive strips 9-1, 9-2 (represented in dotted lines on the figure 1 ), allowing it to be peeled off and replaced by another faceplate bearing another distinctive sign.

A titre d'exemple pratique de mise en oeuvre de l'invention, on a réalisé un présentoir ayant une plaque frontale d'une largeur de 100 mm, d'une hauteur de 60 mm et d'une épaisseur 5 mm. Le bloc d'aspect monolithique formé par les blocs 3 et 5 est un parallélépipède d'une largeur de 90 mm, d'une hauteur de 50 mm et d'une profondeur (épaisseur) de 16 mm. L'ensemble est compact, robuste, prêt à être posé dans une vitrine, est réalisé entièrement en verre acrylique et pèse environ 200 grammes.As a practical example of implementation of the invention, a display unit having a front plate having a width of 100 mm, a height of 60 mm and a thickness of 5 mm was produced. The block of monolithic appearance formed by the blocks 3 and 5 is a parallelepiped with a width of 90 mm, a height of 50 mm and a depth (thickness) of 16 mm. The set is compact, robust, ready to be placed in a showcase, is made entirely of acrylic glass and weighs about 200 grams.

Bien que reposant sur un principe de réflexion de lumière en soi connu, le présentoir selon l'invention forme un objet surprenant pour ceux qui ne connaissent pas sa structure interne. Il suffit de le poser dans un endroit bien éclairé par une lumière verticale ou sensiblement verticale (selon l'orientation donnée au miroir) et le logo, la marque ou autre signe distinctif porté par le présentoir se met à briller comme si une puissante source de lumière était agencée à l'intérieur d'un aussi petit objet.Although based on a known principle of light reflection, the display according to the invention forms a surprising object for those who do not know its internal structure. It is sufficient to put it in a well-lit place with a vertical or substantially vertical light (depending on the direction mirror) and the logo, mark or other distinctive sign worn by the display shines as if a powerful light source were arranged inside such a small object.

Le présentoir selon l'invention est susceptible de diverses variantes de réalisation. Notamment, la plaque frontale 1 et le bloc transparent 5 peuvent être formés par une seule et même pièce. D'autre part, le bloc support 3 et le bloc transparent 5 sont des éléments optionnels qui peuvent être remplacés par un boîtier dans lequel est agencé le miroir. Le miroir peut être agencé sur un support à inclinaison réglable, afin d'adapter le présentoir à diverses conditions d'éclairage. Le miroir peut également être prévu convexe ou concave, ou présenter une surface complexe, si des effets de lumière particuliers sont recherchés. Plusieurs miroirs peuvent également être combinés.The display according to the invention is capable of various embodiments. In particular, the front plate 1 and the transparent block 5 can be formed by a single piece. On the other hand, the support block 3 and the transparent block 5 are optional elements that can be replaced by a housing in which the mirror is arranged. The mirror can be arranged on an adjustable tilt support, in order to adapt the display to various lighting conditions. The mirror may also be provided convex or concave, or have a complex surface, if particular light effects are sought. Several mirrors can also be combined.

La figure 5 représente une variante 20 du présentoir selon l'invention. Celui-ci se distingue du présentoir 10 par le fait que la plaque frontale 1 comprend une avancée 21 formant une corniche sur laquelle un objet 22 peut être posé. La plaque frontale 1 présente ici une zone transparente 2 d'une surface suffisante pour que l'objet 22 soit éclairé par l'arrière. La corniche 21 présente ici un plateau horizontal sur lequel est disposé un deuxième miroir 23. Ce miroir 23 réfléchit certains rayons lumineux transmis par le miroir incliné 4, et assure un éclairage de l'objet 22 par le dessous, qui se combine avec le rétroéclairage.The figure 5 represents a variant of the display unit according to the invention. This is distinguished from the display 10 in that the front plate 1 comprises an advance 21 forming a cornice on which an object 22 can be placed. The faceplate 1 here has a transparent area 2 of sufficient surface area for the object 22 to be illuminated from behind. The ledge 21 here has a horizontal plate on which is disposed a second mirror 23. This mirror 23 reflects some light rays transmitted by the inclined mirror 4, and provides illumination of the object 22 from below, which combines with the backlight .

La figure 6 représente encore une autre variante 30 du présentoir selon l'invention. La plaque frontale 1 est ici d'une épaisseur nettement supérieure à celle du bloc arrière formé par l'association du bloc support 3 et du bloc transparent 5, lequel incorpore le miroir 4. Le dessus de la plaque frontale comprend un support 31 permettant de fixer un objet 32 à présenter au public, par exemple une montre. L'effet esthétique obtenu est avantageux : le présentoir forme un support de l'objet 32 tandis que la marque, le logo ou le signe distinctif se rapportant à l'objet, apparaît sur la face frontale, juste en dessous de l'objet, en caractères lumineux.The figure 6 represents yet another variant of the display according to the invention. The front plate 1 is here of a thickness substantially greater than that of the rear block formed by the combination of the support block 3 and the transparent block 5, which incorporates the mirror 4. The top of the front plate comprises a support 31 allowing fix an object 32 to present to the public, for example a watch. The aesthetic effect obtained is advantageous: the display forms a support for the object 32 while the mark, the logo or the distinctive sign relating to the object, appears on the front side, just below the object, in light characters.

Outre l'affichage d'un signe distinctif ou la présentation d'un objet, un présentoir selon l'invention peut former un objet purement décoratif sans finalité commerciale, pouvant être agencé dans une vitrine, sur un bureau, et de façon générale sous toute source de lumière. A titre d'exemple d'objet décoratif, la plaque frontale peut comprendre une zone transparente (ronde, carrée, rectangulaire, en forme d'étoile...) sur laquelle est agencé un vitrail composé de plusieurs pièces transparentes de couleurs différentes.In addition to the display of a distinctive sign or the presentation of an object, a display unit according to the invention can form a purely decorative object without commercial purpose, which can be arranged in a window, on a desk, and generally under any light source. As an example of decorative object, the front plate may comprise a transparent zone (round, square, rectangular, star-shaped ...) on which is arranged a stained glass composed of several transparent parts of different colors.
