Definitions

  • the present invention concerns a decorative panel for a kitchen cabinet, bathroom closet, wardrobe and general household furniture.
  • the invention may further be applied to decorative panels for doors, shutters and other fixtures.
  • Various decorative designs for these items have been known and widely used for a long time. These designs include panels with beveled sections extending along the edges on all four sides, panels with one or more raised central plates surrounded by grooves with diverse cross sections, panels with one or more central depressions, wherein the depressions may have beveled or rounded edges or edges having any other contours, and many other shapes according to esthetic and functional requirements.
  • plastic laminate does not allow post forming except along the longitudinal axis of the sheet because bending a plastic laminate in a direction perpendicular to the longitudinal axis causes breaking of the fibers that constitute the material.
  • This drawback of the prior art means that any panels covered with plastic laminates can only be made with a bevel or rounded decorative section extending along their longitudinal edges.
  • the transverse edges of the prior art panels must remain straight and level with the top plate and as a result, the range of designs and patterns suitable for the panels of the prior art is limited.
  • Most significantly none of the traditional patterns of either raised or lowered central panels may be achieved by the known methods and any grooves or elevations on the inner area of the panel must always extend in a longitudinal direction.
  • the present invention proposes a novel panel for use as a door for a kithen cabinet, bathroom closet, wardrobe, entrance door and any similar fixture in the household and building at large, characterized in that the basic panel is made of wood, wood laminate, MDF or any suitable material, its top face has bevel or rounded edges on all four sides, it may also have one or more raised or lowered plates inwardly disposed from the said edges and the said top face of the panel is fully finished in plastic laminate such as formica, CPL, HPL etc.
  • the invention also proposes a method for the production of the inventive laminate finished panels wherein on at least one face of a basal panel bevel or rounded longitudinal sections are provided along the edges on all four sides and on which may further be provided raised or lowered surfaces with diverse contours that may extend in various directions other than an axial direction; separate strips of plastic laminate are fitted along the vertical faces of the panel edges, the width of the strip being calculated to allow for working the panel edges to the desired shape, bevel, rounded or other; the panels are laid on a horizontal surface with the top face upwards such that each of the panels is placed within a template made of suitable material such as aluminium, the outer walls of the template following the contours of the panel, the basal panel is covered by a sheet of laminate of a size that allows the laminate to protrude at a distance of several millimeters all around the circumference of the basal panel; suitable bonding material is applied to bond the laminate to the basal panel; rubber sheets cut to fit the size of any depressions are spread above the laminate sheet ; the working surface is introduced into

  • Fig. 4 is a drawing of the inventive means
  • Fig. 5 is an enlarged drawing of the inventive means
  • Fig. 6 is a cross section of the drawing of the inventive means
  • the present invention concerns a novel panel made of suitable hard material such as wood, MDF, wood laminate or any other material known for use in panels for furniture and doors and finished in plastic laminate such as HPL, formica, CPL etc.
  • the panels of the invention are characterised in that at least one face of the panel is made with bevel or rounded or contoured sections along three or four edges and the said face may be decorated with elevated or depressed plates or ridges or grooves inwardly removed from the edges of the said panel and extending along the longitudinal axis, at a straight angle to the longitudinal axis or at any angle to the longitudinal or the transverse axis of the panel.
  • the invention also concerns a method of finishing a panel with a decorative pattern such as described above in plastic laminate.
  • the present invention enables the production of panels for carpentry such as furniture entrance doors, kitchen cabinet doors and panels, bathroom closet doors and panels, wardrobe doors and panels, decorative paneling, shutters etc. having a finish in plastic laminate and having various designs that in the prior art could only be made in PVC finished wood, MDF, wood laminate etc.
  • the panels according to the invention have the advantage of having a novel aspect that is attractive for both designers and customers.
  • the inventive method enables a new range of combinations of structural patterns, finishing textures and colors that did not exist in the prior art.
  • the invention also has the advantage that the quality of the inventive plastic laminate finished panels by far exceeds that of the PVC finished prior art products by being more durable, more colourfast and more resistant to mechanical force.
  • Fig. 1 shows a design for an inventive panel with a central plate and bevel sections extending along the four edges of the panel.
  • the panel comprises a basal panel 8 made of suitable material such as wood or wood laminate or MDF shown in black that is covered with post formed plastic laminate shown in white wherein the said plastic laminate extends continuously all over the surface of the said panel.
  • the top surface of the panel comprises a central plate 1 and a pair of bevel sections 2 and 3 downwardly inclined relative to the plane of the said central plate 1 and extending along the longitudinal edges (of which only the edge 3.1 is visible) of the panel at angles 9.1, 9.2 shown in drawing C.
  • a second pair of bevel sections 4 and 5 is extending along the transverse edges of the panel ( of which only the upper edge 4.1 is visible) downwardly inclined relative to the said plane of the said central plate 1 at angles 10.1, 10.2, shown in drawing B.
  • the novelty of the invention lies in the bevel sections 4 and 5 that according to prior art methods could not be finished in plastic laminate that is continuous with the laminate covering the central plate 1 due to the tendency of the plastic laminate to break along the lines 6,1. Therefore in the prior art the panel of Fig. 1 could only have a single pair of parallel longitudinally extending downwardly inclined bevel sections 2 and 3 whereas the sections 4 and 5 would have to remain in the same plane as the central panel in order to enable a continuous covering by the plastic laminate.
  • Fig. 2 shows another design for an inventive plastic laminate finished panel with downwardly inclined bevel sections along the four outer edges of the panel and a central elevated rectangular plate.
  • the panel comprises a basal panel 8 made of suitable material such as wood or wood laminate or MDF shown in black and it is covered with post formed plastic laminate shown in white wherein the said plastic laminate extends continuously all over the surface of the said panel.
  • this panel comprises a basic plane 1, a pair of bevel sections 2 and 3 extending along the longitudinal edges of the panel (of which only the edge 3.1 is visible)and inclined downwardly from the said basic plane section 1 at angles 9.1, 9.2 shown in drawing C, and a second pair of bevel sections extending along the transverse edges of the panel ( of which only the upper edge 4.1 is visible) downwardly inclined from the said basic plane section 1 at angles 10.1, 10.2, shown in drawing B.

  • the templates may be composite such as the template 5 that is suitable for accommodating three panel units or they may be simple and suited to accommodate a single panel. It will be understood that a long template may be divided by separate transverse sections into a number of templates suitable for several panels of smaller length as necessary.
  • the basal panels 6,7 that are similar in shape to the panel of Fig. 2 and are made of wood or wood laminate or MDF or any suitable material are then placed inside the templates with the faces on which the bevel, elevated and depressed sections are disposed facing upwards.
  • Plastic laminate sheets 8 and 9 are spread with bonding material on their lower surface and placed on the top of each of the basal panels 6 and 7 respectively such that the plastic laminate sheet 8 covers the basal panel 6 and protrudes from the edges of the basal panel 6 to a distance of several millimeters while the plastic laminate sheet 9 covers the basal panel 7 and protrudes to a distance of several millimeters from the edges of the basal panel 7.
  • a rubber sheet 10 is then placed on top of the plastic laminate sheet 8 and a rubber sheet 11 cut to a size that fits the hollow space created by the depression of the central plate of basal panel 7 is placed on top of the plastic laminate sheet 9.

  • the membrane When the pliability of the plastic laminate is suitable for post forming, the membrane is further inflated and pressure under heat is exerted on the plastic laminate causing it to bend along the longitudinal as well as the transverse bending lines created by the three dimensional design of the basal panel surface. Breaking of the laminate along circumferential bending lines is prevented by the template walls and breaking along the lines inwardly removed from the panel edges is avoided due to the resilient rubber sheets.
  • the edges protruding from the basal plane are cut off and worked to a smooth finish.
  • the vertical edges of the basal panel may be finished with a separate strip of laminate before or after the post forming process of the invention.

Abstract

L'invention concerne un panneau pour des portes de meubles, des portes d'entrée et des panneaux, avec au moins une surface ornée de sections longitudinales chanfrennées ou arrondies, sur trois ou quatre côtés et éventuellement dotée de plateaux centraux allongés ou aplatis ou des stries ou rainures qui peuvent être orientées dans diverses directions, longitudinale, transversale ou selon tout angle formé avec les axes longitudinaux ou transversaux du panneau. Ledit panneau apprêté en plastique stratifié peut être du HPL, du CPL ou du Formica. Le plastique stratifié est formé ensuite par courbure sous l'action de la chaleur. On évite les cassures sur des lignes de courbure transversales, en plaçant le panneau de base dans un gabarit et en plaçant au-dessus dudit panneau une feuille de plastique stratifié, légèrement plus large que ledit panneau, de manière à ce que les bords du plastique stratifié soient soutenus par les parois du gabarit, au cours du post-formage le long des bords du panneau. Le matériau excédentaire est ensuite enlévé et un apprêt de plastique stratifié continu et lisse est obtenu. Les formes allongées, aplaties, les stries ou les rainures proviennent d'un espace vide entre le plastique stratifié et le panneau de base dans lequel les couches de plastique doivent être forcées, une feuille de caoutchouc de taille appropriée et assez épaisse est placée au-dessus du plastique stratifié, permettant ainsi de protéger celui-ci d'éventuelles cassures, sous la pression exercée lors du post-formage dudit plastique stratifié.
