Abstract

The invention relates to a removable lampshade of the type comprising a mantle fixed between an upper hoop and a lower hoop. The hoops (14, 15) have in their thickness a groove (18) which can receive by simple introduction the upper or lower edge of the mantle (10), said groove comprising means for pinching the mantle such as protuberances formed on integral legs of the profile.
The invention applies in particular to the manufacture of personalized lampshades.

Description

  • The subject of the invention is a removable lampshade of general cylindrical or conical shape making it possible to present, by light scattering, any document, photo, reproduction or decoration by transparency.
  • The demountable lampshade, in accordance with the invention, is of the general known type comprising a mantle fixed between an upper hoop and a lower hoop, these hoops constitute the mounting carcass of the lampshade.
  • Known removable shades usually have at least some of the following disadvantages:
    • - The frame comprising the two hoops is in the form of a bulky assembly comprising frames joining together the two hoops; such a carcass obviously has a very reduced flexibility of use;
    • - The frame does not include both simple and effective means of mounting and fixing the mantle on it;
    • - the adaptability of a decor determined according to taste and the user's wishes is not taken into account.
  • The object of the invention is to avoid these drawbacks of the prior art by providing a particularly simple and effective mounting lampshade, allowing, from elements of small size, a large choice of combinations giving great flexibility of 'use. In addition, the lampshade of the invention makes it possible to take into account the personalized requests of the user, for example for the adaptation on a lampshade of a photographic decoration or or other document provided by the user.
  • To this end, in accordance with the invention, the demountable lampshade of the type comprising a mantle fixed between an upper hoop and a lower hoop which constitute the mounting carcass of the lampshade is characterized in that said hoops are constituted by profiles having in their thickness a groove which can receive, by simple introduction, the upper or lower edge of the mantle, said groove comprising pinching means of the mantle reducing at least locally the width of introduction of the groove.
  • Advantageously, the aforementioned gripping means are constituted by protuberances provided locally on an edge of the groove and projecting towards the inside of the groove.
  • According to another characteristic of the invention, the coat is made up of several layers gathered together from sheets each having its own individual role: light screening layer, decorative layer and / or protective layer, for example. In particular, the decorative layer can be inserted between a light screening layer and a protective layer, and in this case, this decorative layer can be constituted by a photographic enlargement on translucent film, which enlargement can be carried out from any original document chosen by the user.
  • The invention and its implementation will appear more clearly with the aid of the description which follows made with reference to the appended drawings illustrating by way of example a preferred embodiment. In these drawings:
    • - Figure 1, shows a perspective view of a coat consisting of three superimposed layers, assembled which will enter the construction of a lampshade.
    • - Figure 2 shows in perspective view and schematically in their respective position that iLs occupy after mounting two hoops for the construction of a lampshade and a joint cover that can be used advantageously in addition.
    • Figures 3 and 4 show respectively seen from below and seen from above The upper hoop and The lower hoop of a lampshade.
    • Figures 5 and 6 are sectional views made on a larger scale according to the plans VV and VI-VI of Figure 3.
    • FIG. 7 is a perspective view made diagrammatically on a larger scale of the detail surrounded by VII in FIG. 3.
    • FIG. 8 is a sectional view made substantially along plane VIII-VIII through the joint cover illustrated in FIG. 2.
  • Referring first to Figure 1, The mantle 10 of a lampshade consists of three layers 11, 12, 13 joined together, for example laminated, of .. sheets, each having a role individual clean, such as for example, rigidity and screening of Light for the first inner layer 11, decoration for layer 12 and protection for layer 13. In such a case, layer 11 may have a thickness for example of 20 to 30 hundredths of a millimeter, Layer 12 could be constituted by a photographic enlargement on translucent film in black and white or in color, and Layer 13 could have a thickness of the order of 5 to 10 hundredths of a millimeter. The various layers can be self-adhesive to facilitate their assembly and will advantageously be passed to the manual or mechanical rolling mill so as to obtain a good cohesion of the three sheets of the coat. It should be noted that such a coat will have very good qualities of rigidity and also of light screening.
  • Of course, the dimensions of the coat are adapted to the dimensions of the hoops 14, 15 on which they will come to place the coat. The shape of the cutout, rectangular or circular crown will also depend on the shape chosen for the lampshade, cylindrical, as shown in Figure 2 or for example frustoconical.
  • Referring to Figures 2 to 7, we have shown in more detail how are formed The hoops 14, 15 allowing an easy, fast and effective installation of the coat between the two hoops.
  • Apart from the fact that the lower hoop 15 has in its center a circular support 16 for fixing the lampshade to a lamp base, the support 16 is connected to the profile of the hoop 15 by arms 17, the two profiles 14, 15 of the hoops are advantageously constituted in a substantially identical manner. As can be seen in the drawings, each hoop thus comprises, in its thickness, a groove 18 (FIGS. 5 and 6), the width of which is sufficient to be able to receive, by simple introduction, the upper edge 10a (for the upper hoop 14) or the lower edge 10b (for the lower hoop 15) of the mantle 10, in the assembly position of the lampshade (FIG. 2). To obtain, however, an effective, simple and automatic maintenance of the mantle in the sections 14 and 15, pinch means are provided on each section which preferably consist of protrusions 19 provided locally on an edge of the groove 18 and projecting towards The interior of the groove. Advantageously, these protrusions 19 are formed on a tab 20 (FIG. 7) or tab separated from the rest of the hoop profile by a small cutout 21, each tab or tab 20, with its protrusion 19 thus forming a "clip" LocaL ensuring the correct tightening and correct mounting of the hoop on the coat. In the embodiment of Figures 3 and 4, there are thus provided, on each hoop 14, 15, six legs 20 carrying six protrusions 19, allowing the "clipping" of the mantle 10 in the bottom hoop 15 and in the top hoop 14. Advantageously, these tabs and protuberances are formed on the inner side of the profile so that, from the outside, one does not see the small interruptions or cutouts 21 formed in the profile.
  • To perfect the construction and avoid closing the mantle 10 by gluing or stapling, a joint cover 22 is advantageously provided as it appears in FIG. 2 and the profile of which can be formed as it appears in FIG. 8. This joint cover formed with one foot 23 and a cap 24 makes it possible to receive and maintain the two slices brought back one against the other of the coat 10 positioned in the hoops. In addition, the depth of the grooves 25 of the profile makes it possible to compensate for relatively wide cutting and mounting tolerances.
  • The profiles can advantageously be made of molded plastic material of suitable quality, in particular to have the rigidity and elasticity required for mounting by pinching the mantle in the hoops. Metal profiles can also be used.
  • Many adaptations can be provided, facilitating the use of the lampshade for multiple purposes.
  • Thus, for example, the lower hoop 15 may include a base which will replace the use of a lamp base.
  • The socket support 16 will advantageously be formed so as to meet European standard E27. However, the thickness of the support 16 will be chosen so as to be able to receive conventional rings for reducing the opening allowing the installation of the lampshade on conventional old bulbs of the bayonet type corresponding to European standard E14.
  • Furthermore, although only cylindrical or frustoconical shapes of lampshades have been mentioned previously, it is obvious that the hoops and the mantle can be shaped so as to constitute lampshades of other shapes, for example in trunk of pyramid.
