Definitions

  • the invention relates to a new type of piece of furniture, such as a chair, armchair or table, of the type comprising a base consisting of articulated cross-pieces, on which a support forming a backrest or tray is stretched; armchairs known as AA have been known for a very long time consisting of four rigid rigid tubular cross-pieces, rounded at their ends, on which are housed a canvas forming a backrest and seat.
  • this type of chair has the disadvantage of not being foldable, but only removable.
  • the invention overcomes these drawbacks. It relates to a piece of furniture of the type in question, the base of which consists of cross-pieces on which a support is applied which is foldable, easy to fold and unfold, without scratching the ground.
  • the piece of furniture is a seat which comprises four cross-pieces each cooperating with two other cross-pieces, the two amounts of the two cross-pieces, respectively front and rear, being equal, but the amounts of the front cross-piece being smaller than the amounts rear brace, while the amounts of the two lateral braces are not equal, each brace having a small amount substantially equal to the amounts of the front brace and a large amount substantially equal to the amounts of the rear brace.
  • the support is a trapezoidal fabric, the small base of which is arranged at the front and the large base at the rear, this canvas being fixed to the four upper sleeves by means of gussets provided for this purpose. each of the angles of the trapezoid.
  • Each gusset then has a quick attachment means arranged on the reverse side of the fabric, and on the reverse side of the gusset so as to trap each of the upper sleeves.
  • the seat is a tripod and consists of three braces, the uprights of which each cooperate with the two uprights of the other two braces, the uprights of the front brace being equal, the two lateral braces each having a small amount intended to be directed towards the front, and a large amount intended to be directed towards the rear, the support is then a triangular canvas, the base of which is directed towards the front and the apex towards the rear of similar gussets to the previous gussets of the trapezoidal fabric.
  • the piece of furniture is a table in which the base consists of four cross-pieces, the amounts of which are equal to each other, and the support of which forms a tray and consists of a succession of parallel rollable bars, the face internal tray having hooking means with the upper sleeves to thereby define different heights for positioning the tray, the assembly thus being advantageously foldable.
  • Figure 1 shows a summary perspective view of a four-legged seat base, while Figure 2 shows a trapezoidal support fabric.
  • Figure 3 is a summary perspective view of such a four-legged chair.
  • FIG. 4 shows a first embodiment of an elastic one-piece articulation sleeve and FIG. 5 another embodiment of this sleeve.
  • Figure 6 shows in detail the realization of a gusset.
  • Figure 7 shows the folded chair of Figure 3.
  • Figure 8 shows another embodiment of a tripod seat.
  • Figure 9 shows an embodiment for table.
  • Figure 10 shows in section and in side view a preferred embodiment of the one-piece sleeve characteristic of the invention.
  • Figures 11 and 12 show an embodiment of a four-legged seat.
  • the furniture according to the invention is an armchair with four legs.
  • This chair essentially comprises a base designated by the general reference (1) shown in detail in FIG. 1, intended to receive a support designated by the general reference (2), generally trapezoidal, in canvas, forming the backrest and seat, shown in plan in Figure 2.
  • These characteristic one-piece sleeves (31-38) consist of a rubber or elastomer cylinder reinforced with textile fibers, force-fitted or constricted on the ends of the uprights (1.27).
  • these sleeves are full, and preferably molded. It is important that they are mechanically resistant and return easily and without deformation to their initial position, that is to say with the minimum of afterglow or hysteresis.
  • these sleeves (30) have at each of its two ends (40,41) an equally cylindrical portion (40,41), the diameter of which corresponds substantially to the internal diameter of the uprights . These ends (40,41) are then force-fitted into the corresponding uprights (20,25) and are held in place by a punch (42,43).
  • the sleeve (30) comprises a solid cylindrical body (43), the diameter of which corresponds substantially to the outside diameter of the uprights, for example (20).
  • This body (43) has at each of its two ends, a frustoconical tip (44,45), connected to the body by its small base (46,47).
  • the large base (48) has a diameter slightly larger than the internal diameter of the corresponding upright (20), which allows it to be force-fitted, then to ensure the maintenance of the assembly, it suffices to restrict the end (49) of the corresponding tube (20) on the small frustoconical portion (46), for example by means of a press.
  • the diameter of the body (43) is substantially the same as that of the upright (20), this avoids protruding angles which often cause small injuries, but which above all risks causing tearing of the canvas.
  • the support fabric (2) (see Figures 2 and 6), has a general trapezoidal shape, the small base (50) of which is intended to cooperate with the upper front sleeves (35,38), while the large base (51) cooperates with the rear upper sleeves (36,37).
  • the periphery (52) of this fabric has an overlock and each of the angles (53,54,55,56) has a gusset shown in detail in Figure 6, intended to cooperate with the upper sleeves (35-38).
  • the reverse side (57) of the fabric (2) has, in the vicinity of the gusset (53), a quick coupling member, for example male (58), intended to cooperate with a corresponding member, for example female (59), formed for this purpose on the reverse side of the gusset (53).
  • the articulation axes (15,16,17,18) of the uprights can be produced in any known manner, for example by means of a riveted axis.
  • one of these axes, for example (16) has a strap (60) intended to maintain the assembly in the fully folded position (see FIGS. 1 and 7).
  • the piece of furniture is a tripod seat shown in FIG. 8, consisting of a base designated by the general reference (100) and a triangular support canvas (101), produced in a similar manner to the canvas (2), except that its general shape is triangular and not trapezoidal, and that the base is intended to cooperate with the front and the point with the rear.
  • the support forming a tray designated by the general reference (180), is constituted by a succession of parallel slats (181,182,183), interconnected so as to be able to be rolled up.
  • the lower internal face of the plate (180) comprises hooking means, such as lugs coming from molding or added, intended to cooperate with the upper sleeves (174-177), to block the crosspieces in position and thus adjust the height of the plate (180) relative to the ground.
  • the base (150) and tray (180) assembly is entirely foldable.
  • FIG. 10 shows, as already said, a preferred embodiment of the characteristic one-piece sleeve.
  • This sleeve designated by the general reference (200) is constituted by a solid monobloc piece, injection molded, of elastic thermoplastic material, for example in a polyurethane elastomer loaded with glass fibers and colored.
  • the central body (201) has at each of its ends a head respectively (202) and (203) comprising a male end piece (204 and 205) protruding, chamfered, the diameter of which corresponds substantially to the internal diameter of the braces, to be fitted force and to the diameter of the body (201).
  • These end pieces (204,205) coaxial with the body (201) are surrounded by a covering skirt (206,207) providing with the end piece a space corresponding to the thickness of the braces.
  • skirts (206,207) has toroids (208-211) intended to perfect the tightening of the skirt (206,207) on the end of the braces when they are folded or placed in position.
  • the body and the end pieces are approximately fifteen millimeters in diameter, an overall length of 120 mm, and each skirt has a length of 25 mm for an average diameter (excluding torus) of 20 mm.
  • the furniture is a quadripod seat, consisting of a base designated by the general reference (220) and a rectangular support canvas (221), produced in a similar manner to the canvas (2).
  • the lower ends of all the uprights are interconnected by elastic deformable one-piece sleeves, fitted (240, 243), intended to form a support on the ground.
  • the upper front ends are connected together by two similar sleeves (244,245) on which are housed the gussets not referenced, placed at the two front angles of the support fabric (221) and similar to (55,56).
  • the two rear uprights (227,228) cooperate with the two intermediate lateral uprights (234,235) by means of a slide (250,251) shown in detail in FIG. 12.
  • This one-piece slide made of molded plastic for example made of polyurethane, comprises a connection (252), similar to (201-209) to be fitted at the upper end of the two intermediate lateral uprights (227,228).
  • This connection is integral with a cylindrical ring (253), pierced in its center with an opening (254) also cylindrical and whose diameter is slightly greater than the diameter of the rear uprights (227,228) in order to be able to slide thereon.
  • the upper ends (260,261) of the rear uprights (227,228) receive a rounded support piece (262,263), for example of molded plastic, in particular polypropylene, intended to be housed in the two not shown gussets similar to (53, 54), so that the rear part of the support canvas (221) forms a backrest.
  • a rounded support piece (262,263) for example of molded plastic, in particular polypropylene, intended to be housed in the two not shown gussets similar to (53, 54), so that the rear part of the support canvas (221) forms a backrest.
