Abstract

The invention relates to a device allowing several amusing and decorative optical distortions, namely an effect of curved panoramic vision, an effect of vision with rainbow edges, and effect of upwardly- or downwardly-deflected vision, an effect of squashing of the scenery and finally the fact that the wearer of the device seems to have his eyes shifted in his face. The device according to the invention consists of a transparent prism placed in front of his eyes in the form of a visor or spectacles, which can pivot downwards. This invention relates more particularly to the toy industry.

Description

L'invention consiste en an dispositif à effets optiques déformants multiples. The invention consists of a device with multiple deforming optical effects.

L'invention se rattache au secteur technique du jouet optique.The invention relates to the technical sector of the optical toy.

Les différentes effets optiques ies prismes ont déjà fait l'objet d'analyses et observations scientifiques nombreuses, ainsi que de diverses applications industrielles. Dans cette invention, il s'agit d'une utilisation nouvelle du prisme pour ses effets optiques déformants et en tant que jouet optique, sous forme de visière-lunettes-jouets. En effet, en regardant à travers un prisme transparent, on obtient une vision déformée, qui concourt à plusieurs effets amusants, décoratifs et inattendus
On obtient un phénomène de vision panoramique "courbe", où le plafond (ou le ciel) devient voûté, car toutes les lignes horizontales sont courbées vers le bas (quand le prisme est placé pointe en bas et base en haut), ou vers le haut (quand le prisme est positionné en sens inverse).The various optical effects and prisms have already been the subject of numerous scientific analyzes and observations, as well as various industrial applications. In this invention, it is a new use of the prism for its deforming optical effects and as an optical toy, in the form of a visor-glasses-toys. Indeed, by looking through a transparent prism, one obtains a distorted vision, which contributes to several funny, decorative and unexpected effects
We obtain a phenomenon of panoramic vision "curve", where the ceiling (or the sky) becomes arched, because all the horizontal lines are curved downwards (when the prism is placed point down and base up), or towards the high (when the prism is positioned in the opposite direction).

Un deuxième effet amusant et décoratif est que tous les contours des surfaces, objets, personnes, ont une bordure arc en ciel.A second fun and decorative effect is that all the contours of surfaces, objects, people, have a rainbow border.

Un troisième effet est que, le champ de vision étant décalé du fait de l'effet déviateur du prisme, cela rend la marche difficile, et la prise ou le toucher d'un objet hasardeux.A third effect is that, the field of vision being shifted due to the deflecting effect of the prism, this makes walking difficult, and the taking or touching of a hazardous object.

Un quatriéme effet amusant peut être obtenu en pivotant le prisme de haut en bas devant les yeux: on a ainsi un effet d'écrasement ou d'élongation de la vision. Un exemple de déformation obtenue par cet effet si on tente de descendre un escalier en regardant à travers un prisme positionné pointe en bas, et pivoté vers le bas pour obtenir l'effet écrasement, on à l'impression alors de se trouver en haut d'une échelle raide.A fourth funny effect can be obtained by pivoting the prism up and down in front of the eyes: there is thus a crushing or elongation effect of the vision. An example of deformation obtained by this effect if one tries to descend a staircase by looking through a prism positioned point downwards, and pivoted downwards to obtain the crushing effect, one has the impression then to be at the top d 'a steep ladder.

Enfin, il existe un cinqième effet déformant amusant, celui ci extèrieur à la vision à travers le prisme : la personne qui a le prisme placé devant les yeux semble avoir les yeux décalés et courbés vers le bas, ou vers le haut, selon le sens où l'on a placé le prisme, ce qui lui change totalement la physionomie générale du visage et donne un effet du plus haut comique.Finally, there is a fifth funny distorting effect, this one outside the vision through the prism: the person who has the prism placed in front of the eyes seems to have the eyes shifted and bent down, or up, depending on the direction where the prism has been placed, which totally changes the general physiognomy of the face and gives an effect of the highest comic.

Un mode de réalisation possible de cette invention consiste en un prisme optique dispersif en plastique transparent, d'une longueur égale à la largeur du visage à l'emplacement des yeux, et d'une largeur égale à la grosseur des yeux, et dont la base, placée vers le haut ou vers le bas, est dépolie. Le prisme est monté sur pivots à friction sur des montures, de façon à ajuster l'effet voûte, et pouvoir varier à volonté l'effet écrasement de la vision mentionné plus naut. De façon aussi à pouvoir inverser la position du prisme rour obtenir les effets inversés des effets écrits plus haut.- Les montures sont reliées aux oreilles comme des lunettes classiques
On obtient ainsi dans ce dispositif les 5 effets optiques déformants mentionnés plus haut, à savoir : effet panoramique courbe, effet de bordure arc en ciel, effet de vision décalée, effet d'écrasement, effet des yeux décalés et courbés, ainsi que leur inversion possible en pivotant comnlètement le prisme. One possible embodiment of this invention consists of a transparent plastic dispersive optical prism, of a length equal to the width of the face at the location of the eyes, and of a width equal to the size of the eyes, and whose base, placed up or down, is frosted. The prism is mounted on friction pivots on mounts, so as to adjust the arch effect, and to be able to vary at will the crushing effect of the vision mentioned more nautical. Also in order to be able to reverse the position of the prism rour to obtain the reverse effects of the effects written above.- The frames are connected to the ears like conventional glasses
The 5 distorting optical effects mentioned above are thus obtained in this device, namely: curved panoramic effect, rainbow border effect, offset vision effect, crushing effect, offset and curved eye effect, as well as their inversion possible by fully pivoting the prism.
