FR2887671A1 - Small showcase or cabinet for collector, has horizontal panels, vertical panels, base panel and device for wall fixation, where base panel is made of hardboard or cardboard and adheres on walls of horizontal and vertical panels - Google Patents

Abstract

The showcase or cabinet has horizontal panels (P1, P4), vertical panels (P2, P3) and a base panel (P5). The base panel is made of hardboard or cardboard and adheres on the walls of the horizontal and vertical panels. A device for wall fixation is provided to fix the showcase or cabinet to a wall. Two glasses sliding in a double groove slide are provided in the showcase while the cabinet is provided with an open side. An independent claim is also included for a mode of fabrication of a small showcase or cabinet.

Description

The present invention describes a system of small showcases or small

  modular and economical furniture for collectors and the principle of using extruded or expanded polystyrene used in this manufacture.

  The traditional construction of showcases uses wood or metal, sometimes precious or semi-precious. These components are durable but very expensive: because of this, many collections are not exposed, either because their intrinsic value is too low, or because the collector prefers to invest in his objects rather than in a container. On the other hand, these artisanal fabrications generally include projections of construction or decoration that make it difficult or impossible to juxtapose two window elements when the collection increases.

  The present invention is a double advance in the field of collector showcase because it allows to obtain modular and scalable parts while lowering the cost price.

DESCRIPTION OF THE INVENTION

  This new concept is part of a global research study, manufacturing, marketing of windows and small movable objects non-carrier low cost.

  The search for low cost material, easy to work and widespread enough has led to the use of extruded polystyrene plates 20 to 30 mm thick used in the field of thermal insulation of buildings.

  The advantages and disadvantages of polystyrene are known today, among the main ones: - Low mechanical resistance.

  - Low resistance to ultraviolet.

- Lightness.

- Low cost price.

- Easy to get.

  The low mechanical strength of polystyrene is in the principle of the invention corrected by the use of cardboard or laminate glued on the different sides of the product: it is thus possible to substantially increase the resistance of the elements. Punching effects are also significantly reduced.

  In the same way, this global covering of the polystyrene also protects it from the actions of the ultraviolet rays.

  The lightness of polystyrene makes it easy to handle and significantly reduces the cost of transporting finished products.

  The low cost price of this component is a factor of diffusion increase.

  Another feature of this invention is to allow the obtaining of modular elements, easily juxtaposed, allowing the evolution in quantity of the collection. To do this, taking into account the dimensions desired by the collectors, the basic dimensions of the polystyrene panels and the average maximum dimensions accepted by the courier companies and the post office, two modules and one module are provided (see diagram 4), and on two depths at first.

  The particularity of these elements is to have no roughness on their side faces, which allows their perfect juxtaposition. Access to the interior of the windows is through two sliding windows (mineral or organic glass).

  According to the particular embodiments, the fixed walls of these pieces of furniture consist of assembled panels or of a single molded element.

  The characteristics of the invention are set out in the drawings below, each part or component retaining the same reference in all the figures.

(Figure 3, diagram n el). The assembly is done by gluing with maintenance in press following characteristics of the adhesive used.

  In Figure 3, Figure 2 shows the second method of reinforcing the polystyrene (P) by covering its outer wall with cardboard (C): this cardboard (thickness 1 to 3mm) is glued to the polystyrene wall.

  The inner wall of the polystyrene panel is covered with the internal cladding film (H2) 35 held by gluing, after which the outer faces are covered with the outer cladding film (H1), also glued. This type of assembly is used for horizontal walls which do not have to ensure, on their internal face, of particular mechanical strength. In the case of vertical internal walls that have to support either racks or cleats for shelves (and consequently, the weight of the elements that will be placed on the shelves, the assembly is ensured, as for the outer walls with interposition of cardboard (C) between the polystyrene (P) and the finishing film (H2) (FIG. 3, diagram 3).

  Once the panels dressed, it is proceeded to the assembly of the showcase (or the small non-bearing furniture) by gluing together the four panels constituting the frame of the piece of furniture and put in place before the final tightening of the rear panel ( I) in isorel, also dressed in film (H2), or imitation mirror film, or true mirror. This rear flange is housed in a groove made in the polystyrene parts. After assembly, a soft glue joint is made on the rear face of the furniture, all around its periphery, at the groove and the isorel panel, to increase the rigidity of the assembly, Finally, in Figure 3 , Figure 4 is shown in section a showcase obtained by molding polystyrene (P). The interior faces of this piece of furniture are here covered with a finishing film (H2), while the external faces are covered with cardboard (C) before being decorated by a film (H1). The reinforcement of the molding can also be carried out by covering laminate, both on the internal and external faces.

  The small furniture keeps an open face, while the windows are equipped with two glasses sliding in a double groove slide (plastic or aluminum).

  At the rear of each module is a device for wall mounting.

Claims (5)

  1) Small showcase or piece of furniture comprising a core of extruded polystyrene or expanded polystyrene, sandwiched between them laminated boards or decorated cardboard.   2) Small showcase or composite furniture according to claim 1 characterized in that their frame may be composed of either panels assembled by screwing and gluing, or be obtained in one piece by molding polystyrene.   3) A method of manufacturing small showcases or furniture according to one of the preceding claims characterized by the total modularity of the elements that allows an evolutionary assembly by combination.   4) Small showcases or furniture according to the above claims characterized in that each element may be attached to a wall by a device provided, or placed on a piece of furniture.   5) Small windows or furniture according to one of the above claims characterized in that the lightness of their frame reduces the weight and thereby the cost of routing to the end user,
