Definitions

  • the present invention relates to a hinge, an articulated device formed by or comprising at least one such hinge and a method of manufacturing said hinge.
  • each branch is of different shape, which complicates the manufacture, each branch being formed in one piece by the meeting of two rectangular plates which are arranged in the extension of one another but in parallel planes offset from each other and which are joined in their lower part by a connecting block having two opposite side walls which are rounded and which are each connected to the two longitudinal faces of the plates on the same side thereof.
  • a notch defined by the two edges opposite plates separated by a distance equal to two plate thicknesses, and arranged perpendicularly at right angles to the upper face of the connecting block, which forms the bottom of the notch.
  • the present inventor has sought to make the articulation of the hinge more solid and resistant, which will be demonstrated hereinafter with reference to the Figures 31 to 33 . He therefore sought a solution to manufacture in a simple and solid way a hinge with two movable legs between a position where they lie flat with flat surfaces without cavities, thus achieving the desired aesthetic, and a position where they are arranged crosswise, with 90 ° locking and possibly intermediate locking.
  • a shape of beveled branch of the hinge according to the invention has thus been discovered, which meets the aforementioned objectives and offers the additional advantage of allowing to achieve, also in a simple manner, the hinges with several interlocking grooves, further strengthening the strength hinge and allowing a very large number of possibilities for producing devices articulated to at least one such hinge, a list of examples of such devices being indicated below.
  • the connecting block Unlike the device according to the French patent FR 2 351 623 45 ° bevelled edges allow the connecting block to have a central length of 4e, thus allowing a marked strengthening of the hinge compared to that of the aforementioned French patent. Moreover, the small longitudinal sides of the hinge being in the same plane once the branches applied against each other do not include a vacuum as is the case of the front hinge, in which the inner edge of a notch of a branch is separated from the rounded portion of the connecting block of the other branch.
  • a semi-cylindrical groove opening at the center of the large base of each isosceles trapezoidal surface is formed on the corresponding large longitudinal face of each single or multiple plate or composite in the width direction, the semi-cylindrical grooves being placed opposite to constitute a cylindrical passage during the formation of a single or multiple branch or composite, said hinge having an axis of rotation disposed in said cylindrical passage.
  • the indentations of the single or multiple plates or composed according to their width may be the same, namely l1 - l2.
  • the single or multiple or compound branches may each be formed by two plates bonded together, or at least one of them may be integrally formed.
  • Single or multiple or compound branches may be flat or curved.
  • At least one simple or multiple or composite plate may have, in its region opposite to the notch formed in its thickness, means for joining a structural element or is capable of allowing the joining of a structural element.
  • a single or multiple plate or compound may have a configuration allowing it to be joined with at least one element of an articulated device in which the hinge is intended to be integrated.
  • the two plates of the same branch can be of a different length.
  • the hinge according to the invention may comprise locking means in translation of the axis of rotation.
  • the locking means in an intermediate position or in the 90 ° position may be constituted by a threaded portion of the axis of rotation, which projects from one side of the hinge and is adapted to receive a screw nut in the desired position of branches.
  • the locking means in an intermediate position or in the 90 ° position may be constituted by a first arm, one end of which is fixed on one branch and by a second arm whose one end is fixed on the other branch, the two arms being articulated together at their other ends, a means for locking the arms in their desired relative position being provided.
  • the locking means in an intermediate position or in the 90 ° position may be constituted by a stirrup having the general shape of a U, with a bottom and two wings each formed of a V-shaped wall whose tip is turned towards the inside, thus forming two parts, said yoke being adapted to be positioned by its bottom against the small longitudinal faces of the two branches of the hinge and by its wings against two adjacent portions of branch whose angle corresponds to that of the two parts of the wings of the stirrup.
  • the hinge according to the invention may also comprise a reinforcing plate capable of being applied and fixed against the small longitudinal face of a branch, in its outer part, another reinforcing plate may be provided for the other branch.
  • a multiple or compound hinge may be formed from two respectively multiple or compound branches, one of which does not extend to one side beyond the hexagonal regions.
  • the present invention also relates to an articulated device formed by or comprising at least one hinge as defined above, and chosen in particular from the trivets, the furniture or parts of furniture, the shelves, the trestles, the chairs, the tables, doors, displays, turnstiles.
  • the fastening is performed by screwing in the nesting region.
  • the joining is effected by gluing, each of the plates having been previously glued in the nesting region, the gluing being carried out during the application of the nested plates one on the other.
  • the various plates forming the hinges according to the invention can be made of wood, a hard plastic material, such as polypropylene, polyamide, composites, or a metallic material, such as steel, aluminum and aluminum. 'stainless steel.
  • the plate 1 presents, in a corner part (at the top right if we look at the Figure 1 ), a notch at right angles throughout its thickness e, and at half its width l, to form two end edges 6 and 7, which are chamfered at 45 ° in opposite orientations to form, in the median plane perpendicular to the two large opposite longitudinal faces 2 and 3 of the single plate 1, an isosceles trapezoidal surface 8 whose small and large bases have a length of respectively two times and four times the thickness e of the single plate.
  • a semi-cylindrical groove 9 is formed in the large longitudinal face 2, in the direction of the width of the the simple plate 1, opening, on the one hand, in the center of the large base of the isosceles trapezoidal surface 8 and, on the other hand, in the small longitudinal face 4. Its role is indicated below.
  • the two single plates 1 are placed facing each other and applied against each other so that the two semicircular grooves 9 form a passage P (not shown on FIG. Figures 5 and 6 but that we can see on the Figure 7 which will be described below).
  • Simple plates 1 made of wood or metal, can be obtained by machining.
  • Single plastic plates can be obtained by injection molding or 3D printing.
  • the two single plates 1 are secured by gluing. Thus is formed a branch 10.
  • the simple hinge Cs thus formed can pass from a position in which the branches 10 are applied against each other, forming a flat structure (as can be seen in FIG. Figure 14 which will be described below) at the position of the Figure 7 , for which the branches 10 intersect at 90 °.
  • FIG. 17 and 18 it can be seen that there is shown another embodiment of a simple hinge, namely a simple hinge C's whose branches 10 'are bent, the Figure 17 showing the branches 10 'cross and the Figure 18 , the branches 10 'applied to one another.
  • the hinges of the Figure 7 and Figures 17 and 18 once the branches 10 or 10 'open, can serve as a trivet, which can be folded with the legs 10 or 10' flat on one another for storage.
  • a double plate 11 can be obtained by machining a block of wood or metal or by injection molding or 3D printing.
  • the double plate 11 has two large longitudinal faces 12 and 13 and two small longitudinal faces 14 and 15, two semi-cylindrical grooves 19, two beveled end edges 16 and two bevelled end edges 17.
  • the Figure 9 shows four double plates 11 whose assembly will form a double Cd hinge, as will be described with reference to Figures 14 to 16 .
  • Each of the bevel slots F1, F3 and F5 form, on either side thereof, a bevelled end edge 16 and a bevelled end edge 17 similar to the edges 6 and 7 of the embodiment respectively. just described.
  • a semi-cylindrical groove R is formed, on the same large longitudinal face, from a small longitudinal face to the other, as can be seen on the Figure 10 . There are thus formed four semi-cylindrical grooves 19.
  • each of the two base plates Pb are then glued in the nesting regions of their double plates 11, in the faces 12 comprising the grooves 19.
  • an axis of rotation A is placed in the grooves 19 in alignment with one of the base plates Pb having been cut as indicated above but with its two double plates 11 in the interleaved state.
  • the double hinge shown on the Figure 15 can be used as a trivet in the same way as the hinges of Figures 7 and 17/18 .
  • FIG. 19 it can be seen that there is shown a structure 100 having two double hinges Cd, arranged at a distance from one another.
  • the two double hinges Cd are represented flat views on the Figure 19 their axes being arranged in the extension of one another.
  • the Figure 20 shows a position of the structure 100 with the hinges Cd in the open state.
  • Each of the double plates 11 composing a hinge Cd has opposite the actual articulation part a notch 101 'for the introduction of transverse rods 101.
  • the axes are fixed by end pieces 102.
  • This triple hinge can serve as a trivet in three positions, namely a flat position of the Figure 21 a position in which the axis of the hinge is disposed horizontally and is locked with its two arms crosswise, and a position in which the axis of the hinge is arranged vertically.
  • FIG. 23 there is shown a structure 100 'which differs from the structure 100 in that the bars 101 extend each on the same side to form four feet 103 and that the hinges are simple hinges Cs.
  • Each axis A has a threaded end on which can be screwed a butterfly screw 102 '.
