Description

CARTE DEPLIABLE POUR L'OBTENTION D'UN EFFET OPTIQUE
PAR JUXTAPOSITION DE TRAMES OU MOTIFS ANALOGUES
L'invention concerne une carte dépliable conduisant à l'obtention d'un effet optique, cet effet optique résultant de la mise en oeuvre d'un procédé précédemment décrit par le demandeur dans la demande de brevet français 8 700 839 déposée le 26 janvier 1987. Selon ce procédé précédemment rappelé, l'effet optique cherché est obtenu par juxtaposition à distance l'une de l'autre, de deux trames au moins, l'une au moins de ces trame étant mise en forme.
FOLDABLE CARD FOR OBTAINING AN OPTICAL EFFECT
BY JUXTAPOSITION OF WEBS OR THE LIKE
The invention relates to a foldable card leading to an optical effect, this optical effect resulting from the implementation of a method previously described by the applicant in French patent application 8,700,839 filed on January 26, 1987 According to this previously mentioned process, the desired optical effect is obtained by juxtaposition, at a distance from each other, of at least two frames, at least one of these frames being shaped.

Elle vise en particulier la réalisation de cartes de ce genre qui, à l'état plié, peuvent être placées dans des enveloppes ordinaires et, en particulier, expédiées par la poste de manière habituelle, alors que à l'état déplié, elles prennent une forme concave, qui ne peut être aisémment et sans danger expédiées dans une enveloppe ordinaire. It relates in particular to the production of cards of this kind which, in the folded state, can be placed in ordinary envelopes and, in particular, sent by post in the usual way, while in the unfolded state, they take a concave shape, which cannot be easily and safely shipped in an ordinary envelope.

L'objet de l'invention est de permettre la réalisation d'une carte exploitant cet effet optique et, cependant, pliable pour pouvoir être introduite dans une enveloppe. La présente invention a pour objet une carte dépliable caractérisée en ce qu'elle comprend un panneau postérieur de forme rectangulaire et un panneau antérieur transparent, tous deux ménagés dans des feuilles en matériaux flexibles et ayant même hauteur, la largeur du panneau postérieur étant inférieure à celle du panneau antérieur, ces deux panneaux étant articulés l'un à l'autre par leurs bords latéraux, par deux soufflets chaque soufflet dirigé vers l'arrière du panneau postérieur, présentant à partir d'un pli de jonction, deux soufflets inégaux le plus large aboutissant à un bord latéral du panneau antérieur et l'autre au bord latéral adjacent du panneau postérieur, la différence de largeur des volets de chaque soufflet étant sensiblement égale à la moitié de la différence de largeur des deux panneaux chaque panneau portant les trames ou motif disposés de manière à etre superposés lorsque les panneaux sont plaqués l'un contre l'autre par aplatissement des soufflets. The object of the invention is to allow the realization of a card exploiting this optical effect and, however, foldable to be able to be introduced into an envelope. The present invention relates to a foldable card characterized in that it comprises a rear panel of rectangular shape and a transparent front panel, both formed in sheets of flexible materials and having the same height, the width of the rear panel being less than that of the front panel, these two panels being hinged to one another by their lateral edges, by two bellows each bellows directed towards the rear of the rear panel, having, from a junction fold, two uneven bellows the wider leading to one side edge of the front panel and the other to the adjacent side edge of the rear panel, the difference in width of the flaps of each bellows being substantially equal to half the difference in width of the two panels each panel carrying the frames or pattern arranged so as to be superimposed when the panels are pressed against each other by ap bellows latissement.

Selon une disposition préférée, chaque soufflet est formé par repliement en accordéon de la feuille du panneau postérieur, une bande latérale repliée de la feuille du panneau antérieur étant superposée et fixée au volet adjacent du soufflet. According to a preferred arrangement, each bellows is formed by folding the sheet of the rear panel into an accordion, a folded side strip of the sheet of the front panel being superimposed and fixed to the adjacent flap of the bellows.

Grâce à l'élasticité des matériaux des feuilles dans lesquelles sont ménagés les panneaux, la carte se déplie spontanément, les panneaux se trouvant ainsi espacés l'un de l'autre et l'effet optique recherché étant obtenu notamment du fauit de la forme incurvée résultant de la différence de largeur des deux panneaux. Thanks to the elasticity of the materials of the sheets in which the panels are arranged, the card spontaneously unfolds, the panels thus being spaced from one another and the desired optical effect being obtained in particular from the fauit of the curved shape. resulting from the difference in width of the two panels.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs mieux de la description suivante, donné uniquement à titre d'exemple, en référence aux dessins annexés, dans lesquels:
- la figure 1 est une vue en perspective d'une forme de
réalisation de l'invention, à l'état déplié
pour l'obtention de l'effet optique recher
ché;
- la figure 2 est une vue partielle, à plus grande échelle,
en coupe transversale de la forme de réali
sation de la figure I, à l'état déplié; et
- la figure 3 est une vue analogue à celle de la figu
-re 2, cette fois à l'état replié.
The characteristics and advantages of the invention will emerge more clearly from the following description, given solely by way of example, with reference to the appended drawings, in which:
- Figure 1 is a perspective view of a form of
realization of the invention, in the unfolded state
to obtain the desired optical effect
dear;
FIG. 2 is a partial view, on a larger scale,
in cross section of the real form
sation of Figure I, in the unfolded state; and
- Figure 3 is a view similar to that of the figu
-re 2, this time in the folded state.

Dans la forme de réalisation-choisie et représentée, la carte 1 selon l'invention comprend un panneau postérieur ou d'arrière plan 2 de forme générale rectangulaire, réalisé à partir d'une feuille d'un matériau à flexible, tel que du bristol, carton mince ou un matériau analogue, et un panneau antérieur ou de premier plan 3, de forme générale également rectangulaire, de même hauteur que le panneau 2 et de longueur légèrement supérieure à la longueur de ce panneau 2. In the embodiment-chosen and shown, the card 1 according to the invention comprises a posterior or background panel 2 of generally rectangular shape, produced from a sheet of flexible material, such as Bristol board , thin cardboard or similar material, and an anterior or foreground panel 3, also generally rectangular in shape, of the same height as the panel 2 and of length slightly greater than the length of this panel 2.

Ce panneau 3 est réalisé dans une feuille d'un matériau transparent, également flexible par exemple, une matière plastique. This panel 3 is made of a sheet of a transparent material, also flexible for example, a plastic material.

Les deux panneaux 2 et 3 qui sont superposés, sont réunis l'un à l'autre par leurs bords latéraux 21 et 22 pour la feuille 2, 31 et 32 pour la feuille 3, grâce à deux soufflets 41 et 42 respectivement. Le soufflet 41 représenté aux figures 1 et 2, dirigé vers l'arrière des panneaux 2 et 3, comporte deux volets inégaux 52 et 53, articulés l'un à l'autre autour du pli de jonction 6, et par leurs bords opposés à ce pli, respectivement aux bords latéraux 21 et 31 des feuilles 2 et 3. Le volet 53 est plus large que le volet 52, d'une quantité sensiblement égale.à la moitié de la différence de longueur entre les panneaux 2 et 3. The two panels 2 and 3 which are superimposed, are joined to one another by their lateral edges 21 and 22 for the sheet 2, 31 and 32 for the sheet 3, by means of two bellows 41 and 42 respectively. The bellows 41 shown in FIGS. 1 and 2, directed towards the rear of the panels 2 and 3, comprises two unequal flaps 52 and 53, hinged to each other around the junction fold 6, and by their edges opposite to this fold, respectively at the lateral edges 21 and 31 of the sheets 2 and 3. The flap 53 is wider than the flap 52, by an amount substantially equal to half the difference in length between the panels 2 and 3.

Le soufflet 42 est en tous points analogue au soufflet 41 et ce qui sera dit à propos de l'un des soufflets vaut pour l'autre. Grâce à la différence de largeur des volets 52 et 53, il est possible pour la position repliée de la carte représentée à la figure 3, de plaquer le soufflet 41 contre le dos du panneau 2 (action de la flèche F), les panneaux 2 et 3 étant plaqués également l'un contre l'autre. Cela vaut aussi pour le soufflet 42, comme on l'a déjà dit. The bellows 42 is in all respects analogous to the bellows 41 and what will be said about one of the bellows applies to the other. Thanks to the difference in width of the flaps 52 and 53, it is possible, for the folded position of the card shown in FIG. 3, to press the bellows 41 against the back of the panel 2 (action of the arrow F), the panels 2 and 3 also being pressed against each other. This also applies to the bellows 42, as has already been said.

Ainsi la carte repliée et plate, peut être introduite dans une enveloppe. Thus the folded and flat card can be inserted in an envelope.

Dans la position dépliée (figures 1 et 2), les soufflets 41 et 42 s'écartent du panneau 2 et, ainsi par rotation du volet 52 autour du pli 6, le panneau 2 se trouve écarté du panneau 3. In the unfolded position (FIGS. 1 and 2), the bellows 41 and 42 move away from the panel 2 and, thus by rotation of the flap 52 around the fold 6, the panel 2 is moved away from the panel 3.

Pour faciliter ce dépliement, il est avantageux de réaliser chaque soufflet par repliement en accordéon de la zone latérale de la feuille prolongeant le panneau 2, le volet 41 (et son homologue de l'autre bord) étant constitué par superposition et collage d'une bande latérale de la feuille de panneau 2, et d'une bande latérale repliée de la feuille du panneau 3, l'élasticité du matériau des feuilles assurant le dépliement lorsque la pression selon la flèche F es relâchiée
Pour l'obtention de l'effet optique recherché de manière connue, les panneaux 2 et 3 portent chacun des trames, grilles ou motifs analogues superposables 60, 61, 62, dont la juxtaposition à distance dans l'état déplié de la carte, fournit précisément cet effet optique.
To facilitate this unfolding, it is advantageous to produce each bellows by folding in accordion from the lateral zone of the sheet extending the panel 2, the flap 41 (and its counterpart on the other edge) being formed by superposition and bonding of a lateral strip of the panel sheet 2, and a folded lateral strip of the panel sheet 3, the elasticity of the material of the sheets ensuring the unfolding when the pressure according to the arrow F is released
To obtain the desired optical effect in a known manner, the panels 2 and 3 each carry frames, grids or similar superimposable patterns 60, 61, 62, the remote juxtaposition of which in the unfolded state of the card, provides precisely this optical effect.

Lors du dépliement, grâce à la forme des soufflets 41, 42 les deux panneaux prennent une forme incurvée, la concavité des panneaux étant tournée vers l'observation, ce qui contribue à l'effet optique du à la juxtaposition des trames ou autres motifs. During unfolding, thanks to the shape of the bellows 41, 42 the two panels take a curved shape, the concavity of the panels being turned towards observation, which contributes to the optical effect due to the juxtaposition of the frames or other patterns.

Bien entendu, la présente invention n'est pas limitée aux modes de réalisation décrits et représentés mais elle-est susceptible de nombreuses variantes accessibles à l'homme de l'art sans que'l'on ne s'écarte de l'esprit de l'invention.  Of course, the present invention is not limited to the embodiments described and shown, but it is susceptible of numerous variants accessible to those skilled in the art without departing from the spirit of the invention.
