Abstract

The lampshade (1) for a standard or ceiling lamp is supported by a frame (2) consisting of rings of different sizes, giving the required shape. They are not connected by vertical members, e.g. they can form parts of a spiral, so that the frame can be folded flat for storage and transport. The covering material is made of plastics and is applied in a suitable manner by e.g. spraying which also allows the whole to be folded flat. The frame may also carry a structure incorporating threads, connecting wires etc., resembling a spider's web so that plastics sprayed over it will dry to form a coating. The structure can then be removed.

Description

"Abat-jour constitué d'une seule pièce repliable
et procédé pour sa fabrication".
"Lampshade made of a single foldable piece
and process for its manufacture ".

L'invention a pour objet un abat-jour constitué d'une seule pièce et repliable, d'un support portant l'abat-jour et un revêtement composé d'une matière synthétique, textile ou d'un matériau semblable. The subject of the invention is a lampshade consisting of a single piece and foldable, a support carrying the lampshade and a covering composed of a synthetic, textile or similar material.

Les formes-d'exéeution différentes des abat-jour existant sur le marché se composent le plus souvent d'un support ou ossature qui est revêtu ou garni d'un matériau, par exemple de tissu, papier, feuille de matière plastique ou analogues. Les supports ou assatures ont pour but de conserver à l'abat-jour une forme donnée. Ils se composent, le plus souvent, de fils de fer ou métalliques rigides, sur lesquels sont soudés, ensemble, des anneaux séparés au moyen d'entretoises, de sorte que le support garde en permanence sa forme donnée. The different forms of execution of the lampshades existing on the market most often consist of a support or framework which is coated or lined with a material, for example fabric, paper, plastic sheet or the like. The supports or assemblies are intended to keep the lampshade a given shape. They consist, most often, of rigid iron or metallic wires, onto which are welded, together, separate rings by means of spacers, so that the support permanently retains its given shape.

Ces abat-jour ainsi construits présentent un grave inconvénient, car ils ont besoin d'excessivement de place pour l'emballage et l'expédition mais le volume pour l'emballage et l'expédition coute très cher, si bien que les abat-jour sont, pour l'expédition, autant que possible placés-ou glissés les uns dans les autres, possibilité qui ne donne aucune satisfaction et d'autre part conduit ainsi à aucune économie importante de place. These lampshades thus constructed have a serious drawback, since they require excessive space for packaging and shipping, but the volume for packaging and shipping is very expensive, so that the lampshades As far as possible, they are placed or slipped into each other for shipping, a possibility which gives no satisfaction and on the other hand thus leads to no significant saving of space.

Le but de l'invention consiste à créer des abat-jour qui, malqré leur forme d'exécution en une seule pièce, sont repliables de façon telle qu'ils ne prennent, emballés, pendant le transport, que la place la plus petite possible. The object of the invention is to create lampshades which, despite their form in one piece, are foldable so that they take up, packed, during transport, only the smallest possible place. .

L'invention concerne à cet effet un abat-jour du type ci-dessus, caractérisé en ce aue le support portant et formant 1 r abat-our se compose d'éléments disposés radialement et perpendiculairement à l'axe de l'abat-jour, éléments disposés sous forme circulaire ou polygonale sans liaison les uns avec les autres. The invention relates for this purpose to a lampshade of the above type, characterized in that the support carrying and forming 1 r lampshade consists of elements arranged radially and perpendicular to the axis of the lampshade , elements arranged in circular or polygonal form without connection with each other.

Des dispositions indiquées dans la suite permettent d'obtenir des modes de réalisation avantageux de l'invention. Provisions indicated in the following allow advantageous embodiments of the invention to be obtained.

Par la suppression des entretoisements supérieurs appliqués au support ou à l'ossature, ces abatjour peuvent être comprimés en une configuration plate horizontale jusqu'à environ la dixième partie de la hauteur d'un tel abat-jour. By eliminating the upper braces applied to the support or the framework, these lampshades can be compressed into a horizontal flat configuration up to approximately the tenth part of the height of such a lampshade.

Il peut être logé, de cette manière, en cas d'emballage, environ dix abat-jour pour une même utili- sation de la place, pendant cue, autrefois, seulement un abat-jour de type classique prenait place dans ce volume de transport en position debout. A leur lieu d'utilisation, les abat-jour sont simplement séparés et accrochés. Les plis éventuellement formés pendant le transport et par l'emballage se sont très vite éliminés et l'abat-jour présente de nouveau, dans un court délai, une surface lisse. It can be accommodated, in this way, in the event of packaging, approximately ten lampshades for the same use of the place, during cue, formerly, only one lampshade of the traditional type took place in this transport volume in standing up position. At their place of use, the lampshades are simply separated and hung. Any folds formed during transport and by the packaging were quickly eliminated and the lampshade again had a smooth surface within a short time.

L'invention s'étend à un-procédé pour fabriquer un abat-jour du type ci-dessus, caractérisé en ce qu'on dispose coaxialement les éléments du support sur un dispositif de maintien constitué par une broche avec des moyeux et des rayons, on franchit les grandes distances éventuelles entre les éléments du support au moyen de fils minces, de fils métalliques, d'hélices ou similaires, on projette une matière synthétique liquide sur ces éléments du support et on élimine ensuite en les retirant ces fils fils métalliques, hélices ou similaires. The invention extends to a process for manufacturing a lampshade of the above type, characterized in that the support elements are arranged coaxially on a holding device constituted by a spindle with hubs and spokes, the possible great distances between the elements of the support are crossed by means of thin wires, metal wires, propellers or the like, a liquid synthetic material is projected onto these elements of the support and these metal wires are then eliminated by removing them, propellers or the like.

L'invention sera mieux comprise en regard de la description ci-après-et des dessins annexés représentant des exemples de réalisation de l'invention, dessins dans lesquels
- les figures-la et lb montrent un abat-jour en position d'utilisation pour une lampe de chevet ou verticale (fig. la) et en position repliée (figure lb)
- les figures 2a et 2b montrent un abat-jour de forme cylindrique comme on l'utilise d'une manière avantageuse, par exemple, entre autre, en cas de lampes suspendues ou de. lampes de plafond.
The invention will be better understood with reference to the description below and the appended drawings representing examples of embodiment of the invention, drawings in which
- Figures-la and lb show a lampshade in the use position for a bedside or vertical lamp (fig. la) and in the folded position (figure lb)
- Figures 2a and 2b show a cylindrical shade as used in an advantageous manner, for example, among others, in the case of hanging lamps or. ceiling lamps.

Les éléments 2 horizontaux ou sensiblement horizontaux, disposés autour de l'axe vertical théorique 3 de l'abat-jour, et de formes cylindriques ou aussi polygonales, ne sont pas reliés ensemble dans une direction verticale, afin qu'un abat-jour ainsi constitué puisse être comprimé comme un ressort en spiral, jusqu'à environ la dixième partie de sa hauteur. Il peut ainsi rester dans cette situation jusqu'à cé qu'il soit ànouveau tiré vers l'extérieur Un ou plusieurs éléments circulaires 2 peuvent être aussi, naturellement réunis à des anneaux doubles 2a, ou être reliés ensemble aussi par des entretoises 2b.  The elements 2 horizontal or substantially horizontal, arranged around the theoretical vertical axis 3 of the lampshade, and of cylindrical or also polygonal shapes, are not connected together in a vertical direction, so that a lampshade thus constituted can be compressed like a spiral spring, up to approximately the tenth part of its height. It can thus remain in this situation until it is again pulled outwards. One or more circular elements 2 can also, naturally, be joined to double rings 2a, or be connected together also by spacers 2b.
