Definitions

  • the invention relates to a self-supporting spatial structure, particularly for furniture construction, such as closets, cabinets, shelves, book shelves, especially display units and customised furniture sets.
  • Commonly known furniture structures are made of cellulose raw materials in the form of wooden boards and/or other wood-like or composite materials in order to obtain structurally defined shapes of the components, with enhancement treatment of the material surface, joining of the machined components with hardware or pins or screws or nails or by adhesive bonding of properly prepared ends of the components and/or upholstering of certain components, such as seats, backrests, cushions, and the mounting of hinges, wheels, brakes, handles.
  • Such structures composed of conventional furniture components, have many limitations, such as difficulty in obtaining thick walls so as to avoid a significant increase in the mass of the furniture structure, inability to make butt joints of two different boards, inability to obtain a rounded (curved) furniture corner when using oblique joints and, above all, the necessity to use furniture edging products, the application of which requires a separate production process.
  • the inventive box is made from a unitary blank of material.
  • the box when assembled, has four interconnected sidewalls that define an open storage area between them.
  • the sidewalls are typically each rectangular in shape, to define a generally rectangular prism-shaped storage area.
  • Blank is also formed through die cutting and creasing of corrugated material. Blank comprises first, second, third and fourth sidewall portions respectively.
  • the object of the present invention is to develop a simple and inexpensive technology to manufacture a wide range of exhibition furniture based on paper, cardboard, sandwich panels and furniture hardware, with the possible use of other materials.
  • the essence of the invention is that the self-supporting spatial structure is created by folding the cut-out sheet constructed in accordance with claim 1.
  • each of the symmetrical trapeziums touching each other with shorter bases is provided with square or rectangular holes located in parallel to each other and create pairs into which the locking-joining insert is installed.
  • the cross-section of the groove has the V-shaped or U-shaped profile.
  • the sheet is a laminated composite material in the form of the AL/LDPE/AL laminate folded along the lines created by single-sided or double-sided removal of the AL material to create a single-sided or double-sided groove in the composite material.
  • the incised sheet once folded, is stiffened at the back with a flat element inserted into the internal contour of the created geometric solid.
  • the element that stiffens and closes the back of the structure and joins the overlap portions is made of plywood.
  • the self-supporting structure created by incising the sheet and once folded, is open on one side and fixed to the flat board with screws passing through the holes in the folded overlaps.
  • the self-supporting structure created by incising the sheet and once folded, is open on one side and fixed to a flat board with a block covering the folded overlaps using bolts or screws passing through the holes in the block and in the folded overlaps.
  • This design of the furniture system is suitable to create various geometric solids and all shapes of the furniture by using a laminated composite panel, which can be incised and folded to adapt the shape to the needs and demands of the user, as shown below in the description and drawing.
  • the laminate surface may be printed with any pattern or image, resulting in a smooth transition of decorative artistic forms from the front to the side walls and a very pleasing and useful visual effect.
  • the sheet has incisions creating two parallel rows of four rectangles 1 separated by symmetrically-placed triangles 2, the apexes of which coincide with the line of incision of the first row and the apex angle 3 is 90°, and the two rows of rectangles 1 are joined by the trapeziums 4, which are equipped at their outer edges with foldable triangular, trapezoidal or rectangular overlaps 5, wherein in the second rows the rectangles 1 are separated from each other by the trapeziums 6 touching each other along shorter bases, wherein the bases form the line of incisions and are located in the line of incision of the first row of rectangles squares and, wherein rhombic pass-through cut-outs 7 are formed between symmetrically placed triangles and symmetrical trapeziums.
  • the symmetrical trapeziums 6 are provided with rectangular openings 8, into which the locking-joining insert 9 is installed and slips 10, during the final sheet folding phase.
  • the overlaps 5 are provided with openings 11.
  • the insert 12 provided with incisions 13 is inserted into the folded sheet.
  • sheet folding creates a shelf structure. To stiffen it at the back, insert 14 is installed.
  • a change of the apex angle causes that the angle between the walls created out of the rectangles 1 after sheet folding is complemented to obtain 180°.
  • the cut-out sheets may be attached to the supporting board 15 using the blocks 16 that are bolted 17 together and locked with protrusions 18.
  • the created spatial structures may be equipped with doors 19, as in the example in Fig. 32 .
