Definitions

  • the present patent application for industrial invention relates to a cardboard seat.
  • Cardboard is undoubtedly one of the most environmentally-friendly materials because it is completely recyclable, biodegradable and made with natural elements and additives.
  • cardboard has proved to be one the most appropriate materials for the realization of environmentally-friendly interior decoration items.
  • the market currently offers various types of cardboard seats that are obtained by folding and/or gluing a punched cardboard sheet.
  • the seat in addition to having to choose the correct type of glue carefully in order not to prevent seat recycling and to avoid visible thickness between glued parts, the seat inevitably maintains its three-dimensional condition, without the possibility of being dismounted to return to the bi- dimensional condition of the original punched cardboard sheet.
  • the advantage of said "folding" seats is that they occupy a very reduced space during storage, require minimum packaging volumes and minimize transportation costs.
  • the purpose of the present invention is to remedy the drawbacks of the prior art, by devising a cardboard seat that is strong, stable, easy and fast to assemble.
  • the cardboard seat of the invention is obtained by folding a single cardboard sheet that is the base structure of the seat of the invention.
  • the base structure is composed of four consecutive quadrangular sections separated by a folding line.
  • Each of said consecutive four sections is folded by approximately 90° with respect to the adjacent section in order to close the base structure along a quadrangular direction; said cardboard seat also comprises fixing means adapted to hold the structure in three-dimensional condition provided on a first transversal side of the base structure and on an imaginary line.
  • FIG. 1 is a plan view of the base structure used to obtain the cardboard seat according to the invention
  • - Figure 2 is an axonometric view of the base structure of Fig. 1 ;
  • FIG. 3 is an exploded axonometric view of the cardboard seat according to the invention.
  • FIG. 4 is an axonometric view of the cardboard seat according to invention.
  • FIGS. 5 and 6 are respectively an axonometric view and a side view of the end portion of an end section provided in the cardboard seat according to the invention.
  • the cardboard seat of the invention is obtained using a base structure (A) with substantially rectangular shape, and comprising two parallel longitudinal long sides (B,C), of which a first longitudinal long side (B) and a second longitudinal long side (C), as well as two parallel transversal sides (D,E), of which a first transversal short side (D) and a second transversal short side (E).
  • A base structure with substantially rectangular shape, and comprising two parallel longitudinal long sides (B,C), of which a first longitudinal long side (B) and a second longitudinal long side (C), as well as two parallel transversal sides (D,E), of which a first transversal short side (D) and a second transversal short side (E).
  • Said base structure (A) is composed of five quadrangular sections (1 ,
  • Said lines consist in three folding lines (L1 , L2, L3) and one imaginary line (X).
  • first quadrangular section (1 ) defined by the first transversal side (D) of the base structure (A), a first portion (B1 ) of the first longitudinal long side (B), a first portion (C1 ) of the second longitudinal long side (C) and a first folding line (L1 );
  • a V-sectioned groove is provided in each folding line (L1 , L2, L3) of the base structure (A) in order to obtain perfect overturning between two adjacent quadrangular sections (1 , 2, 3, 4, 5).
  • the third section (3) rests on the ground, the first section (1 ) acts as seat, and the fifth section (5) acts as backrest.
  • the first transversal side (D) is provided with fixing means adapted to cooperate with corresponding housings obtained in the imaginary line (X), against which said first transversal short side (D) is stopped.
  • said fixing means consist in end sections (6) inserted in said housings, which specifically consists in slots (7).
  • Each end section (6) comprises an intermediate portion (61 ) and an end portion (62).
  • said intermediate portion (61 ) is exactly inserted into the corresponding slot (7), therefore having length equal to the horizontal dimension of said slot (7) and width equal to the thickness of the base structure (A).
  • Said end portion (62) protrudes with respect to said slot (7) wherein the end section (6) is inserted, and is provided with two opposite grooves (64) with diverging concavity.
  • Said opposite grooves (64) house a ring (63) adapted to prevent the backward sliding of each end section (6) from the slot (7).
  • said ring (63) is dimensioned in such way that the horizontal dimension (63a), when measured in its external border, is higher than the horizontal dimension of the slot (7) where the end section (6) is inserted.
  • the cardboard seat of the invention can advantageously comprise a washer (65) disposed between said two opposite grooves (64) and the surface of the base structure (A) from which the end portions (62) of the end sections (6) protrude.
  • Said washer (65) is centrally provided with a slot that receives the end portion (62) of a single end section (6).
  • the cardboard seat of the invention can advantageously be provided with two stiffening edges (8) in order to give stability and sturdiness to the seat of the invention.
  • the seat of the invention comprises centering and fixing means for said stiffening edges (8) adapted to make it easier to assemble the edges in the seat, and guarantee the stable position of the stiffening edges (8) with respect to the seat, when the latter is in assembled condition.
  • said centering means consist in a series of tabs situated on the edge and a series of housings situated on said base structure.
  • said series of tabs comprises a first tab (81 ), a second tab (82), a third tab (83) and a fourth set of three tabs (84).
  • Said housings are situated on the first four quadrangular sections (1 , 2, 3, 4) of the base structure (A) and consist in through slots (9) obtained on the longitudinal long sides (B, C) of the base structure (A).
  • said through slots (9) are previously obtained on cardboard strips (90) glued on said longitudinal long sides (B, C) of the base structure (A).
  • the present invention also relates to a stool without backrest obtained with the same base structure (A), but without the fifth quadrangular section (5).
