Definitions

  • the present invention concerns a process for manufacturing a honeycomb structured panel, adapted to be used for realizing furniture and furnishings components of various kind.
  • the invention also relates to a honeycomb structured panel obtained with the above mentioned manufacturing process.
  • the doors and the wings for wardrobes and furniture and furnishing components in general are advantageously made by utilizing large quantities of honeycomb structured panels, which have a very low specific weight, which makes lighter these products ; should these wardrobes, furniture and components be made with simple chipboard panels or medium density (MDF) panels, which have a very higher specific weight, they would be very heavier.
  • MDF medium density
  • honeycomb structured panel is also used frequently for panels with large thickness, for realizing flanks for wardrobes, shelves, planes for living-rooms and any application requiring a light weight, not to be deformable and sturdiness associated with considerable thicknesses for the technicians of the field.
  • This honeycomb structured panel guarantees an increase of the strength and the stability of the single elements and consequently of the entire realized structure and a longer duration of the screw anchoring junctions, even after repeated assembling operations.
  • a process for manufacturing a honeycomb structured panel is known, adapted to be employed for assembling furniture and having characteristics of lightness and mechanical resistance, which foresees the construction of a peripheral frame of wood, or constituted by chipboard or medium density (MDF) materials.
  • MDF medium density
  • honeycomb made structure In un subsequent step, in the fully empty zone being created in the interior of such frame, it is introduced a honeycomb made structure, then in a subsequent operative step and in the upper part and lower part of said frame it is applied a respective covering panel always made of chipboard, medium density (MDF) material or plywood, thereby closing the so obtained honeycomb structured panel.
  • MDF medium density
  • honeycomb made structure may be constituted by an alveolar structured paper or, for increasing additionally the resistance and the structural characteristics of the panel, the structure may be constructed with ingots of foamed
  • honeycomb structured panel is squared and flanged on the four sides thereof at the final sizes of the furniture component to be realized, with the edge of the same colour of the surface.
  • honeycomb structured panel is normally ennobled and machined like a normal chipboard panel, with the application of veneerings, laminates, polymeric or melaminic sheets.
  • a second process of known type consists of glueing two layers, usually made of chipboard, medium density (MDF) material or plywood having dimensions identical to those ones of the chipboard panels in commerce, in the interior of which an alveolar structure with very small alveolus of rigid type is inserted.
  • MDF medium density
  • the so obtained panel is cutaway at the final sizes of the furniture component to be realized, and is flanged at a considerable extent, in that the wood strip isn't provided, in accordance to the same previously described process. In this case, the screws need some expanding bushes.
  • a drawback of the above mentioned known manufacturing technologies of a honeycomb structured panel consists of the need to square and flange the panels, which steps are effected by employing different types of machineries and which involve long and expensive working times, and the production of a lot of scraps of the utilized materials, both in the squaring and the trimming step.
  • Another drawback of such known processes consists in that the global aesthetical appearance of the honeycomb structure panel is getting worse by the presence of the flanging, namely of the line interrupting two subsequent edges, which is clearly visible in correspondence of each edge joining two sides, so that for obtaining a honeycomb structured panel with an agreeable and not discontinuous appearance, along the peripheral surface thereof it is needed to perform a possible lacquering step, which is also expensive in term of working time and costs.
  • the object of the present invention is to eliminate the above mentioned drawbacks, by means of a manufacturing process allowing to produce honeycomb structured panels in a simple, quick and continuous manner, adapted to realize a continuous peripheral surface, by eliminating in particular the flanging step, and therefore by reducing the manufacturing times, and with considerably reduced production costs.

  • Such engravings 15 are spaced away transversally to each other in a way to define the correspondent external edges of the external body 10, which will be folded later along all the different engravings 15, so as to adapt the same entire external body on to the first central body 9 as it will be described later on.
  • two engravings 15 are provided parallel to each other in the respective side positions of the body 10, by defining two short side strips 19 and 20 with the same width and delimited by a relative side edge 21 and 22, which are shaped for being able to be coupled to each other, while two additional engravings 15 are provided, parallel to each other and with respect to the previous engravings, in the central area of the external body 10, and they are spaced away to each other of a distance equal to the widths of both said side strips 19 and 20, and each one of these engravings is spaced away from the opposite engraving of the same area of surface 23, for being able then to house and to wrap the central body 9 with the external body 10.
  • the lower larger surface 24 of such central body 9 is laid on and fixed with an adhesive on to one of the surfaces of the first component element 11, in the Figures constituted by the right surface, in a manner that the vertical side edges 25 and 26 of such central body 9 be arranged in correspondence of the relative engravings 15, wherein the left side edge 25 be located near the surface portion 27 delimited by the engravings of the central area of the external body, while the right side edge 26 be located near the side strip 20, the width of which is preferably the half of the height of the same side edge.

  • strips 19 and 20 are put at first into contact to each other and then are coupled opportunely, i.e. through fixed joint etc... by letting themselves to adhere perfectly to the correspondent right side vertical side edge 26 of the central body 9, thereby defining the other surface portion opposed to the preceding portion 27, wherein the joining area of the two side strips 19 and 20 doesn't appear visible and so confers a continuous aesthetical appearance even to this surface portion of the so formed honeycomb structured panel.
  • the central body 9 is realized with five sides instead of four sides as in the case of the Fig. 6 A, and also the external body 10 is shaped with five sides correspondent to those ones of the central body 9, and in the same external body there are provided additional engravings 15 in correspondence of the different edges of these sides of the central body 9, and the external body 10 is applied on to the central body 9 in a manner identical to the above described manner.

Moreover, this process allows to realize a bar-shaped honeycomb structured panel, with sizes which can be obtained to measure and by shortening the working times of the different operative steps and therefore with less stocks of wares.
