  • the present invention relates to a waking mat and activity, of the type comprising a plurality of rigid panels articulated to each other by flexible joints, and attachment means for arranging the mattress in at least a first and a second configurations.
  • Awakening and activity mattresses of the above-mentioned type are known, in which each panel is formed by a foam plate housed in a respective chamber of a cover. Each chamber is bounded by stitches linking the opposite sides of the cover to one another. The articulation of the different panels relative to each other is along the stitches.
  • each foam plate is manually inserted into its respective chamber, which forces to have a chamber wider than the foam plate that is housed therein. As a result, the foam plate can move in its respective chamber. This results in the formation of large interstices between the panels, which reduce the insulation of the mattress with the ground, reduce its comfort by making the surface irregular, and may be a trap in which a child could get stuck.

Description

La présente invention concerne un matelas d'éveil et d'activité, du type comprenant une pluralité de panneaux rigides articulés les uns aux autres par des articulations souples, et des moyens d'attache pour disposer le matelas dans au moins une première et une deuxième configurations. On connaît des matelas d'éveil et d'activité du type précité, dans lesquels chaque panneau est formé par une plaque de mousse logée dans une chambre respective d'une housse. Chaque chambre est délimitée par des points de couture liant les faces opposées de la housse l'une à l'autre. L'articulation des différents panneaux les uns par rapport aux autres se fait le long des points de couture.The present invention relates to a waking mat and activity, of the type comprising a plurality of rigid panels articulated to each other by flexible joints, and attachment means for arranging the mattress in at least a first and a second configurations. Awakening and activity mattresses of the above-mentioned type are known, in which each panel is formed by a foam plate housed in a respective chamber of a cover. Each chamber is bounded by stitches linking the opposite sides of the cover to one another. The articulation of the different panels relative to each other is along the stitches.

Ces produits présentent plusieurs inconvénients. Tout d'abord, les points de couture fragilisent la housse, et sont eux même susceptibles de rompre. Le fait qu'ils soient localisés dans une zone aussi sollicitée que les articulations des panneaux conduit souvent à des déchirures et à une désolidarisation des panneaux.These products have several disadvantages. First, the stitches weaken the cover, and are themselves likely to break. The fact that they are located in an area as stressed as the joints of the panels often leads to tears and a separation of the panels.

De plus, les tolérances en matière de couture font que les points de couture sont rarement parfaitement alignés. Il en résulte une mauvaise articulation des panneaux les uns par rapport aux autres.In addition, the sewing tolerances mean that the stitches are rarely perfectly aligned. This results in poor articulation of the panels relative to each other.

Enfin, à la fabrication, chaque plaque de mousse est insérée manuellement dans sa chambre respective, ce qui oblige à avoir une chambre plus large que la plaque de mousse qui y est logée. Il en résulte que la plaque de mousse peut bouger dans sa chambre respective. Cela a pour conséquence la formation d'interstices importants entre les panneaux, qui réduisent l'isolation du matelas avec le sol, diminuent son confort en en rendant la surface irrégulière, et risquent de constituer un piège dans lequel un enfant pourrait se coincer. GB 2 297 915 divulgue un couffin présentant un contour extérieur et comprenant une pluralité de panneaux rigides articulés les uns aux autres par des articulations souples sans couture. Un objectif de l'invention est d'obtenir un matelas d'éveil et d'activité résistant et adapté pour être disposé dans différentes configurations. D'autres objectifs sont d'avoir un coût marginal de production réduit, d'améliorer l'isolation, le confort et/ou la sécurité du matelas, et d'avoir un grand nombre de configurations d'utilisation possibles pour le matelas.Finally, during manufacture, each foam plate is manually inserted into its respective chamber, which forces to have a chamber wider than the foam plate that is housed therein. As a result, the foam plate can move in its respective chamber. This results in the formation of large interstices between the panels, which reduce the insulation of the mattress with the ground, reduce its comfort by making the surface irregular, and may be a trap in which a child could get stuck. GB 2,297,915 discloses a basket having an outer contour and comprising a plurality of rigid panels hinged to each other by seamless flexible hinges. An object of the invention is to obtain a waking mat and activity resistant and adapted to be arranged in different configurations. Other objectives are to have a marginal cost of production reduced, to improve the insulation, comfort and / or safety of the mattress, and to have a large number of possible configurations of use for the mattress.

Le matelas d'éveil et d'activité 10, représenté sur la Figure 1 comprend une pluralité de panneaux 12, 14 rigides articulés les uns aux autres par des articulations 16 souples. Il comprend en outre des volets 18 souples interposés entre certains panneaux 14, et des organes 20, 22 d'attache pour disposer le matelas 10 dans différentes configurations.The awakening mat and activity 10, shown on the Figure 1 comprises a plurality of rigid panels 12, 14 articulated to each other by flexible hinges 16. It further comprises flexible flaps 18 interposed between certain panels 14, and members 20, 22 for attaching the mattress 10 in different configurations.

Le matelas 10 présente un contour extérieur 24 en forme de polygone, ici en forme d'hexagone régulier.The mattress 10 has an outer contour 24 in the form of a polygon, here in the form of a regular hexagon.

Il comprend une région centrale 26, sensiblement centrée sur le centre du matelas 10, et une région périphérique 28, délimitant le contour extérieur 24.It comprises a central region 26, substantially centered on the center of the mattress 10, and a peripheral region 28 delimiting the outer contour 24.

La région centrale 26 a une forme homothétique de celle du contour extérieur 24.The central region 26 has a homothetic shape of that of the outer contour 24.

La région périphérique 28 s'étend de la région centrale 26 au contour 24.The peripheral region 28 extends from the central region 26 to the contour 24.

Le matelas 10 présente également une fente traversante 30 débouchant dans une face supérieure 32 (Figure 6) et dans une face inférieure 34 du matelas 10.The mattress 10 also has a through slot 30 opening into an upper face 32 ( Figure 6 ) and in a lower face 34 of the mattress 10.

La fente traversante 30 s'étend du contour extérieur 24 jusqu'au centre du matelas 10. Elle s'étend le long d'une médiane du polygone, entre les panneaux 12, 14.The through slot 30 extends from the outer contour 24 to the center of the mattress 10. It extends along a median of the polygon, between the panels 12, 14.

La face supérieure 32 est sensiblement plane.The upper face 32 is substantially flat.

La face inférieure 34 est irrégulière. Elle présente des bossages 36 et des creux 38. Les bossages 36 sont formés par les parties rigides du matelas 10, c'est-à-dire les panneaux 12, 14. Les creux 38 sont formés par les parties souples du matelas 10, c'est-à-dire les articulations 16 et les volets 18.The lower face 34 is irregular. It has bosses 36 and recesses 38. The bosses 36 are formed by the rigid parts of the mattress 10, that is to say the panels 12, 14. The recesses 38 are formed by the flexible parts of the mattress 10, c i.e. the joints 16 and the flaps 18.

Les panneaux 12, 14 comprennent une pluralité de panneaux centraux 12, disposés dans la région centrale 26, et une pluralité de panneaux périphériques 14, disposés dans la région périphérique 28.The panels 12, 14 comprise a plurality of central panels 12, arranged in the central region 26, and a plurality of peripheral panels 14, arranged in the peripheral region 28.

Les panneaux centraux 12 sont superposables les uns aux autres. Chaque panneau central 12 a la forme d'un secteur de polygone, ici d'hexagone. En particulier, chaque panneau central 12 a la forme d'un quadrilatère présentant un angle de sensiblement 120°, la bissectrice de cet angle formant un axe de symétrie du quadrilatère.The central panels 12 are stackable with each other. Each central panel 12 has the shape of a polygon sector, here hexagon. In particular, each central panel 12 has the shape of a quadrilateral having an angle of substantially 120 °, the bisector of this angle forming an axis of symmetry of the quadrilateral.

Les panneaux centraux 12 sont juxtaposés les uns aux autres de sorte à former ensemble le polygone régulier de la région centrale 26. Les panneaux centraux 12 sont ainsi articulés les uns aux autres le long de médianes du polygone régulier de la région centrale 26.The central panels 12 are juxtaposed to each other so as to form together the regular polygon of the central region 26. The central panels 12 are thus articulated to each other along the medians of the regular polygon of the central region 26.

Chaque panneau central 12 est articulé à deux autres panneaux centraux 12, et à deux panneaux périphériques 14. Chaque panneau central 12 est ainsi articulé à un autre panneau 12, 14 le long de chacun de ses côtés.Each central panel 12 is hinged to two other central panels 12, and two peripheral panels 14. Each central panel 12 is thus articulated to another panel 12, 14 along each of its sides.

Les panneaux centraux 12 sont ici au nombre de six.The central panels 12 are here six in number.

Les panneaux périphériques 14 sont superposables les uns aux autres. Chaque panneau périphérique 14 occupe toute la largeur de la région périphérique 28, c'est-à-dire qu'il s'étend de la région centrale 26 jusqu'au contour extérieur 24.The peripheral panels 14 are stackable with each other. Each peripheral panel 14 occupies the entire width of the peripheral region 28, that is to say that it extends from the central region 26 to the outer contour 24.

Chaque panneau périphérique 14 a une forme sensiblement rectangulaire, en particulier sensiblement carrée.Each peripheral panel 14 has a substantially rectangular shape, in particular substantially square.

Pour chaque côté du contour extérieur 24, deux panneaux périphériques 14 sont disposés le long de ce côté. Ces panneaux périphériques 14 sont articulés l'un à l'autre le long d'une médiatrice dudit côté, ladite médiatrice s'inscrivant dans le prolongement d'une médiane du polygone régulier de la région centrale 26.For each side of the outer contour 24, two peripheral panels 14 are arranged along this side. These peripheral panels 14 are articulated to one another along a mediator of said side, said mediator being in the extension of a median of the regular polygon of the central region 26.

Chaque panneau périphérique 14 est également articulé à un panneau central 12.Each peripheral panel 14 is also articulated to a central panel 12.

Chaque panneau périphérique 14 n'est articulé à un autre panneau 12, 14 que le long de deux de ses quatre côtés.Each peripheral panel 14 is hinged to another panel 12, 14 only along two of its four sides.

Les panneaux périphériques 14 sont dans cet exemple au nombre de douze.In this example, the peripheral panels 14 are twelve in number.

Chaque volet 18 est disposé dans la région périphérique 28. Il est interposé entre deux panneaux périphériques 14, et délimite un angle du contour extérieur 24.Each flap 18 is disposed in the peripheral region 28. It is interposed between two peripheral panels 14, and delimits an angle of the outer contour 24.

Chaque volet 18 a une forme homothétique de celle d'un panneau central 12. Dans l'exemple représenté, chaque volet 18 a ainsi la forme d'un quadrilatère présentant un angle de sensiblement 120°, la bissectrice de cet angle formant un axe de symétrie du quadrilatère. Ledit angle de 120° constitue l'angle du contour extérieur 24 que délimite le volet 18.Each flap 18 has a homothetic shape of that of a central panel 12. In the example shown, each flap 18 thus has the shape of a quadrilateral having an angle of substantially 120 °, the bisector of this angle forming an axis of symmetry of the quadrilateral. Said angle of 120 ° constitutes the angle of the outer contour 24 delimited by the shutter 18.

Les volets 18 sont dans cet exemple au nombre de six.The flaps 18 are in this example six in number.

En référence aux Figures 2 et 3, la structure du matelas 10 va maintenant être décrite en détail. On notera que, quand bien même seuls deux panneaux périphériques 14, seule l'articulation 16 entre ces panneaux et seul un volet 18 adjacent à l'un de ces panneaux 14 sont représentés, cette description est applicable à tous les panneaux 12, 14, à toutes les articulations 16 et à tous les volets 18 du matelas 10.With reference to Figures 2 and 3 , the structure of the mattress 10 will now be described in detail. It will be noted that, even if only two peripheral panels 14, only the articulation 16 between these panels and only one flap 18 adjacent to one of these panels 14 are shown, this description is applicable to all the panels 12, 14, to all the joints 16 and all the flaps 18 of the mattress 10.

Chaque panneau 12, 14 comprend une première grande face 40, une deuxième grande face 42, opposée à la première grande face 40, et un bord périphérique 44.Each panel 12, 14 comprises a first large face 40, a second large face 42, opposite the first major face 40, and a peripheral edge 44.

La première grande face 40 délimite une partie de la face supérieure 32 du matelas 10. La deuxième grande face 42 et le bord périphérique 44 délimitent chacun une partie de la face inférieure 34 du matelas 10.The first large face 40 delimits a portion of the upper face 32 of the mattress 10. The second major face 42 and the peripheral edge 44 each delimit a portion of the lower face 34 of the mattress 10.

La première grande face 40 et la deuxième grande face 42 s'étendent sensiblement parallèlement l'une à l'autre. La première grande face 40 est plus grande que la deuxième grande face 42.The first major face 40 and the second major face 42 extend substantially parallel to each other. The first large face 40 is larger than the second major face 42.

Le bord périphérique 44 est biseauté, c'est-à-dire qu'il est incliné relativement à une perpendiculaire aux grandes faces 40, 42. Le bord périphérique 44 forme en particulier un angle compris entre 40° et 50° relativement à ladite perpendiculaire.The peripheral edge 44 is beveled, that is to say that it is inclined relative to a perpendicular to the large faces 40, 42. The peripheral edge 44 forms in particular an angle between 40 ° and 50 ° relative to said perpendicular .

Chaque panneau 12, 14 comprend une feuille de tissu supérieure 50 et une feuille de tissu inférieure 52 prenant ensemble une plaque de mousse 54 en sandwich.Each panel 12, 14 comprises an upper fabric sheet 50 and a lower fabric sheet 52 together sandwiching a foam plate 54.

Chaque feuille de tissu 50, 52 est en matériau synthétique, par exemple en polyester.Each sheet of fabric 50, 52 is made of synthetic material, for example polyester.

La feuille de tissu supérieure 50 délimite la première grande face 40. Elle est venue de matière avec la feuille de tissu supérieure 50 de chaque autre panneau 12, 14.The upper fabric sheet 50 delimits the first major face 40. It is integral with the upper fabric sheet 50 of each other panel 12, 14.

La réunion des feuilles de tissu supérieures 50 des différents panneaux forme ainsi une grande feuille de tissu supérieure d'un seul tenant. Cette grande feuille de tissu supérieure définit l'intégralité de la face supérieure 32. Elle forme une partie de chaque articulation 16, et une partie de chaque volet 18.The meeting of the upper fabric sheets 50 of the different panels thus forms a large sheet of superior fabric in one piece. This large sheet of upper fabric defines the entirety of the upper face 32. It forms part of each articulation 16, and part of each flap 18.

La feuille de tissu inférieure 52 délimite la deuxième grande face 42, et la bordure 44. Elle est venue de matière avec la feuille de tissu inférieure 52 de chaque autre panneau 12, 14.The lower fabric sheet 52 defines the second major face 42, and the edge 44. It is integral with the lower fabric sheet 52 of each other panel 12, 14.

La réunion des feuilles de tissu inférieures 52 des différents panneaux forme ainsi une grande feuille de tissu inférieure d'un seul tenant. Cette grande feuille de tissu inférieure définit l'intégralité de la face inférieure 34. Elle forme une partie de chaque articulation 16, et une partie de chaque volet 18.The meeting of the lower fabric sheets 52 of the different panels thus forms a large sheet of lower fabric in one piece. This large sheet of lower fabric defines the entirety of the lower face 34. It forms part of each articulation 16, and part of each flap 18.

La plaque de mousse 54 est en mousse synthétique, par exemple en éthylène acétate de vinyle.The foam plate 54 is made of synthetic foam, for example ethylene vinyl acetate.

La plaque de mousse 54 a sensiblement la même forme que le panneau 12, 14 correspondant. Elle présente une première grande face 56, et une deuxième grande face 58, opposée à la première grande face 56 et s'étendant sensiblement parallèlement à cette dernière. Elle présente également une bordure biseautée 60.The foam plate 54 has substantially the same shape as the corresponding panel 12, 14. It has a first large face 56, and a second large face 58, opposite the first major face 56 and extending substantially parallel thereto. It also has a bevelled edge 60.

La feuille de tissu supérieure 50 est apposée à la première grande face 56. En particulier, elle adhère à la première grande face 56, au moins à la périphérie de celle-ci.The upper fabric sheet 50 is affixed to the first large face 56. In particular, it adheres to the first major face 56, at least at the periphery thereof.

La feuille de tissu inférieure 52 est apposée à la deuxième grande face 58 et à la bordure biseauté 60. En particulier, elle adhère à la bordure biseauté 60. De préférence, elle adhère également à la deuxième grande face 58.The lower fabric sheet 52 is affixed to the second large face 58 and the bevelled edge 60. In particular, it adheres to the bevelled edge 60. Preferably, it also adheres to the second large face 58.

On notera que « adhérer » est ici et dans la suite utilisé pour désigner une liaison chimique directe entre les éléments. Le terme « adhérer » exclut ici le cas où les éléments seraient liés l'un à l'autre par un adhésif tiers.It will be noted that "adhere" is here and hereinafter used to denote a direct chemical bond between the elements. The term "adhere" here excludes the case where the elements would be bonded to one another by a third-party adhesive.

Dans la variante présentée sur la Figure 2, les plaques de mousse 54 des différents panneaux 12, 14 sont venues de matière les unes avec les autres. Pour chaque paire de panneaux 12, 14 articulés l'un à l'autre par une articulation 16, un pont de matière 62 en mousse liant les plaques de mousse 54 desdits panneaux 12, 14 s'étend dans ladite articulation 16. Ce pont de matière 62 est interposé entre la grande feuille de tissu supérieure et la grande feuille de tissu inférieure, qui adhèrent toutes les deux audit pont de matière 62.In the variant presented on the Figure 2 , the foam plates 54 of the various panels 12, 14 are integral with one another. For each pair of panels 12, 14 articulated to each other by a hinge 16, a bridge of foam material 62 bonding the foam plates 54 of said panels 12, 14 extends in said hinge 16. This bridge material 62 is interposed between the large upper fabric sheet and the lower large fabric sheet, both of which adhere to said material bridge 62.

Chaque articulation 16 est ainsi formée par une partie de la grande feuille de tissu supérieure, une partie de la grande feuille de tissu inférieure et un pont de matière 62 reliant les plaques de mousse 54 des panneaux 12, 14 articulés l'un à l'autre par ladite articulation 16.Each hinge 16 is thus formed by a portion of the large upper fabric sheet, a portion of the large lower fabric sheet and a material bridge 62 connecting the foam plates 54 of the panels 12, 14 articulated to each other. other by said articulation 16.

Dans la variante présentée sur la Figure 3, les plaques de mousse 54 des différents panneaux 12, 14 sont indépendantes les unes des autres et espacées les unes des autres. Il n'y a donc pas de mousse qui s'étend dans aucune articulation 16In the variant presented on the Figure 3 , the foam plates 54 of the various panels 12, 14 are independent of each other and spaced apart from each other. There is therefore no foam that extends into any articulation 16

Dans chaque articulation 16, la grande feuille de tissu supérieure est donc en contact direct avec la grande feuille de tissu inférieure. Ces grandes feuilles de tissu adhèrent l'une à l'autre dans l'articulation 16. Elles définissent entre les articulations 16 des poches individuelles 64, chaque poche 64 contenant la plaque de mousse 54 d'un panneau 12, 14.In each articulation 16, the large upper tissue sheet is in direct contact with the large lower tissue sheet. These large sheets of tissue adhere to one another in the hinge 16. They define between the joints 16 individual pockets 64, each pocket 64 containing the foam plate 54 of a panel 12, 14.

Chaque articulation 16 est ainsi formée exclusivement par une partie de la grande feuille de tissu supérieure et une partie de la grande feuille de tissu inférieure, lesdites grandes feuilles adhérant l'une à l'autre dans l'articulation 16.Each hinge 16 is thus formed exclusively by a portion of the large upper tissue sheet and a portion of the large lower tissue sheet, said large sheets adhering to each other in the hinge 16.

Ainsi, dans la variante de la Figure 2 comme dans la variante de la Figure 3, chaque articulation 16 est formée par une pluralité de couches pressées et adhérant les unes aux autres. Cette adhérence des couches assure la cohésion de l'articulation 16 sans qu'il ne soit nécessaire de coudre ces couches les unes aux autres. Chaque articulation 16 est donc sans couture.So, in the variant of the Figure 2 as in the variant of the Figure 3 each hinge 16 is formed by a plurality of pressed layers adhering to each other. This adhesion of the layers ensures the cohesion of the hinge 16 without the need to sew these layers to each other. Each hinge 16 is seamless.

On notera que les variantes des Figures 2 et 3 peuvent être combinées sans sortir du cadre de l'invention. En d'autres termes, dans certaines variantes de l'invention, les plaques de mousse 54 d'une première partie des panneaux 12, 14 sont venues de matière les unes avec les autres, et les plaques de mousse 54 d'au moins une deuxième partie des panneaux 12, 14 sont indépendantes des plaques de mousse 54 des panneaux 12, 14 de la première partie. Ainsi, certaines articulations 16 sont formées de la grande feuille de tissu supérieure, de la grande feuille de tissu inférieure et du pont de matière 62, et d'autres articulations 16 sont formées exclusivement de la grande feuille de tissu supérieure et de la grande feuille de tissu inférieure.It will be noted that the variants of Figures 2 and 3 can be combined without departing from the scope of the invention. In other words, in certain variants of the invention, the foam plates 54 of a first part of the panels 12, 14 have come from material with each other, and the foam plates 54 of at least a second portion of the panels 12, 14 are independent of the foam plates 54 of the panels 12, 14 of the first part. Thus, some joints 16 are formed of the large upper tissue sheet, the lower large tissue sheet and the material bridge 62, and other joints 16 are formed exclusively of the large tissue sheet and the large tissue sheet. of lower fabric.

Chaque volet 18 est formé exclusivement des grandes feuilles de tissu supérieure et inférieure, lesdites feuilles adhérant l'une à l'autre.Each flap 18 is formed exclusively of large sheets of upper and lower fabric, said sheets adhering to each other.

Les organes d'attache 20, 22 vont maintenant être décrits, en référence aux Figures 4 et 5.The fasteners 20, 22 will now be described with reference to Figures 4 and 5 .

Chaque organe d'attache 20, 22 comprend un corps allongé 70, et une tête 72, 74 solidaire d'une extrémité longitudinale du corps 70. Le corps 70 et la tête 72, 74 sont typiquement venus de matière.Each fastener 20, 22 comprises an elongated body 70, and a head 72, 74 secured to a longitudinal end of the body 70. The body 70 and the head 72, 74 are typically made of material.

Chaque organe d'attache 20, 22 est avantageusement en plastique, par exemple en polyéthylène basse densité.Each fastener 20, 22 is advantageously made of plastic, for example low density polyethylene.

Le corps 70 de chaque organe 20, 22 a sensiblement la même longueur que le corps 70 de chaque autre organe 20, 22.The body 70 of each member 20, 22 has substantially the same length as the body 70 of each other member 20, 22.

Le corps 70 comprend une partie cylindrique 76, et une nervure 78.The body 70 comprises a cylindrical portion 76, and a rib 78.

La partie cylindrique 76 s'étend parallèlement à la direction d'élongation du corps 70, sur toute la longueur du corps 70. Elle est pleine.The cylindrical portion 76 extends parallel to the direction of elongation of the body 70 over the entire length of the body 70. It is full.

La nervure 78 fait saillie depuis une surface circonférentielle de la partie cylindrique 76. Elle est allongée parallèlement à la direction d'élongation du corps 70. Elle s'étend sur plus de 90% de la longueur du corps 70.The rib 78 projects from a circumferential surface of the cylindrical portion 76. It is elongated parallel to the elongation direction of the body 70. It extends over more than 90% of the length of the body 70.

Les organes d'attache 20, 22 comprennent au moins un premier organe d'attache 20, comprenant une tête femelle 72, et au moins un deuxième organe d'attache 22, comprenant une tête mâle 74, les têtes mâles 74 et femelles 72 étant adaptées pour coopérer les unes avec les autres pour assurer la liaison de chaque premier organe d'attache 20 à chaque deuxième organe d'attache 22. En particulier, la tête mâle 74 de chaque premier organe d'attache 20 est adaptée pour pénétrer dans la tête femelle 72 de chaque deuxième organe d'attache 22 pour lier lesdits organes 20, 22 l'un à l'autre.The fastening members 20, 22 comprise at least one first fastening member 20, comprising a female head 72, and at least one second fastening member 22, comprising a male head 74, the male heads 74 and the female heads 72 being adapted to cooperate with each other to ensure the connection of each first fastening member 20 to each second fastening member 22. In particular, the male head 74 of each first fastener 20 is adapted to enter the female head 72 of each second attachment member 22 for connecting said members 20, 22 to each other.

A cet effet, la tête femelle 72 est en forme de boucle, et la tête mâle 74 est en forme de tige, la tête mâle 74 présentant un diamètre extérieur inférieur au diamètre intérieur de la tête femelle 72.For this purpose, the female head 72 is loop-shaped, and the male head 74 is rod-shaped, the male head 74 having an outer diameter smaller than the inner diameter of the female head 72.

En particulier, la tête mâle 74 a un diamètre extérieur maximal supérieur à celui de la partie cylindrique 76 du corps 70, et présente un tronçon 80 de diamètre extérieur croissant entre son extrémité 82 de liaison au corps 70 et sa région 84 de diamètre extérieur maximal. Cela permet d'assurer une meilleure tenue de la tête mâle 74 dans la tête femelle 72.In particular, the male head 74 has a maximum outside diameter greater than that of the cylindrical portion 76 of the body 70, and has a section 80 of increasing outer diameter between its end 82 of connection to the body 70 and its diameter region 84. maximum outside. This ensures a better holding of the male head 74 in the female head 72.

Avantageusement, comme représenté, la tête mâle 74 est raccordée au corps 70 par l'intermédiaire d'un coude 86. Ainsi, la tête mâle 74 est orientée dans une direction différente de la direction d'élongation du corps 70. Cela permet de faciliter l'insertion de la tête mâle 74 dans la tête femelle 72.Advantageously, as shown, the male head 74 is connected to the body 70 via a bend 86. Thus, the male head 74 is oriented in a direction different from the direction of elongation of the body 70. This facilitates the insertion of the male head 74 into the female head 72.

Le coude 86 s'étend dans un plan perpendiculaire à la nervure 78.The elbow 86 extends in a plane perpendicular to the rib 78.

Les premiers organes 20 sont en même nombre que les deuxièmes organes 22.The first members 20 are of the same number as the second members 22.

En référence à la Figure 1, chaque premier organe d'attache 20 est logé dans un volet 18. Sa tête femelle 72 est à sensiblement équidistance des panneaux périphériques adjacents 14 audit volet 18.With reference to the Figure 1 each first fastening member 20 is housed in a flap 18. Its female head 72 is substantially equidistant from adjacent peripheral panels 14 to said flap 18.

Le corps 70 s'étend d'un premier desdits panneaux périphériques adjacents 14 jusqu'à la tête 72. Le corps 70 rigidifie ainsi en partie le volet 18.The body 70 extends from one of said adjacent peripheral panels 14 to the head 72. The body 70 thus partially stiffens the flap 18.

En particulier, le corps 70 s'étend le long de l'un des côtés du volet 18.In particular, the body 70 extends along one of the sides of the shutter 18.

A chaque premier organe d'attache 20 est associé un deuxième organe d'attache 22 qui est logé dans l'un desdits panneaux périphériques adjacents 14, avantageusement, comme représenté, dans le deuxième panneau périphérique adjacent 14.Each first fastening member 20 is associated with a second fastening member 22 which is housed in one of said adjacent peripheral panels 14, advantageously as shown in the adjacent second peripheral panel 14.

Le corps 70 de ce deuxième organe d'attache 22 s'étend depuis le volet 18, à l'opposée du volet 18. Il s'étend en particulier parallèlement à un côté du panneau périphérique 14, notamment le long d'un côté non articulé du panneau périphérique 14.The body 70 of this second attachment member 22 extends from the flap 18, opposite the flap 18. It extends in particular parallel to one side of the peripheral panel 14, in particular along a non-rigid side. articulated peripheral panel 14.

La tête 74 de ce deuxième organe d'attache 22 est orientée à l'opposée du volet 18, c'est-à-dire que son extrémité libre 88 est plus éloignée du volet 18 que son extrémité de liaison 82.The head 74 of this second attachment member 22 is oriented opposite the flap 18, that is to say that its free end 88 is further away from the flap 18 than its connecting end 82.

Dans des variantes de l'invention, les organes d'attache 20, 22 sont remplacés par d'autres moyens d'attache, comme des velcros, des ficelles, ou autres.In variants of the invention, the fasteners 20, 22 are replaced by other attachment means, such as velcro, string, or other.

Différentes configurations du matelas 10 vont maintenant être décrites, en référence aux Figures 1, 6 et 7.Different configurations of the mattress 10 will now be described, with reference to Figures 1 , 6 and 7 .

Sur la Figure 1, le matelas 10 est représenté dans une configuration tapis d'éveil, dans laquelle il est sensiblement plan. En d'autres termes, pour chaque paire de panneaux 12, 14 adjacents, l'angle formé entre les premières grandes faces 40 desdits panneaux 12, 14 est sensiblement égale à 180°. Les organes d'attache 20, 22 sont à distance les uns des autres et ne coopèrent pas les uns avec les autres.On the Figure 1 , the mattress 10 is shown in a waking carpet configuration, in which it is substantially plane. In other words, for each pair of panels 12, 14 adjacent, the angle formed between the first large faces 40 of said panels 12, 14 is substantially equal to 180 °. The fasteners 20, 22 are spaced from each other and do not cooperate with each other.

Sur la Figure 6, le matelas 10 est représenté dans une configuration centre de jeu, dans laquelle les panneaux périphériques 14 font saillie relativement aux panneaux centraux 12, les panneaux centraux 12 étant alignés dans un même plan. Pour chaque paire de panneaux centraux 12 adjacents, l'angle formé entre les premières grandes faces 40 desdits panneaux 12 est sensiblement égal à 180°. Pour chaque paire de panneaux central 12 et périphérique 14 adjacents, l'angle formé entre les premières grandes faces 40 desdits panneaux 12, 14 est sensiblement égal à 90 °.On the Figure 6 , the mattress 10 is shown in a play center configuration, in which the peripheral panels 14 project relative to the central panels 12, the central panels 12 being aligned in the same plane. For each pair of central panels 12 adjacent, the angle formed between the first major faces 40 of said panels 12 is substantially equal to 180 °. For each pair of adjacent central panels 12 and peripheral 14, the angle formed between the first large faces 40 of said panels 12, 14 is substantially equal to 90 °.

Les panneaux périphériques 14 forment un contour fermé autour des panneaux centraux 12.The peripheral panels 14 form a closed contour around the central panels 12.

Les panneaux périphériques 14 sont maintenus en saillie par les organes d'attache 20, 22. A cet effet, la tête femelle 72 de chaque premier organe d'attache 20 est engagée sur la tête mâle 74 du deuxième organe d'attache 22 associé. Ainsi, les bords périphériques 44 des panneaux périphériques 14 adjacents au volet 18 dans lequel est logé le premier organe d'attache 20 sont maintenus en contact l'un avec l'autre, position qui ne peut être atteinte que lorsque lesdits panneaux périphériques 14 sont en saillie relativement au panneau central 12 qui leur est adjacent.The peripheral panels 14 are held protruding by the fastening members 20, 22. For this purpose, the female head 72 of each first fastening member 20 is engaged on the male head 74 of the second fastening member 22 associated. Thus, the peripheral edges 44 of the peripheral panels 14 adjacent to the flap 18 in which the first fastening member 20 is housed are held in contact with each other, a position which can only be attained when said peripheral panels 14 are protruding relative to the central panel 12 adjacent thereto.

On notera que, la tête mâle 74 de chaque deuxième organe d'attache 22 étant orientée à l'opposée du volet souple 18, lorsque les panneaux périphériques 14 sont ainsi en saillie, la force qu'ils exercent sur le premier organe d'attache 20 associé pour revenir en position alignée avec les panneaux centraux 12 sollicite la tête femelle 72 vers l'extrémité 82 de liaison de la tête mâle 74 au corps 70 du deuxième organe 22. Les risques pour que les têtes mâle 74 et femelle 72 se désengagent l'une de l'autre sont ainsi réduits.Note that, the male head 74 of each second fastener member 22 being oriented opposite the flexible flap 18, when the peripheral panels 14 are thus projecting, the force they exert on the first fastening member 20 associated to return to the aligned position with the central panels 12 urges the female head 72 towards the end 82 of the male head 74 connection to the body 70 of the second member 22. The risks for the male heads 74 and female 72 disengage from each other are thus reduced.

Sur la Figure 7, le matelas 10 est représenté dans une configuration canapé, dans laquelle les panneaux périphériques 14 font saillie relativement aux panneaux centraux 12, une moitié des panneaux centraux 12 étant alignés dans un même plan, l'autre moitié étant superposée sur la première moitié de panneaux centraux 12. Pour deux paires de panneaux centraux 12 adjacents, l'angle formé entre les premières grandes faces 40 desdits panneaux 12 est sensiblement égal à 0°. Pour chaque autre paire de panneaux centraux 12 adjacents, l'angle formé entre les premières grandes faces 40 desdits panneaux 12 est sensiblement égal à 180°. Pour chaque paire de panneaux central 12 et périphérique 14 adjacents, l'angle formé entre les premières grandes faces 40 desdits panneaux 12, 14 est sensiblement égal à 90°.On the Figure 7 , the mattress 10 is shown in a sofa configuration, in which the peripheral panels 14 project relative to the central panels 12, one half of the central panels 12 being aligned in the same plane, the other half being superimposed on the first half of panels 12. For two pairs of adjacent central panels 12, the angle formed between the first major faces 40 of said panels 12 is substantially equal to 0 °. For each other pair of adjacent central panels 12, the angle formed between the first large faces 40 of said panels 12 is substantially equal to 180 °. For each pair of adjacent central panels 12 and peripheral 14, the angle formed between the first large faces 40 of said panels 12, 14 is substantially equal to 90 °.

Les panneaux centraux 12 sont accolés deux à deux le long de leurs premières grandes faces 40 et forment une assise.The central panels 12 are placed side by side along their first large faces 40 and form a seat.

Les panneaux périphériques 14 sont accolés deux à deux le long de leurs premières grandes faces 40 et forment un dossier sur un côté de l'assise.The peripheral panels 14 are placed side by side along their first large faces 40 and form a file on one side of the seat.

De même que dans la deuxième position, les panneaux périphériques 14 sont maintenus en saillie par les organes d'attache 20, 22.As in the second position, the peripheral panels 14 are held protruding by the fastening members 20, 22.

Un procédé de production du matelas 10 va maintenant être décrit, en référence aux Figures 8 et 9.A method of producing the mattress 10 will now be described, with reference to Figures 8 and 9 .

Lors d'une première étape, un moule 100, comprenant une matrice 102 et un poinçon 104, est fourni. La matrice 102 et le poinçon 104 délimitent ensemble une chambre 106 de production du matelas 10.In a first step, a mold 100, comprising a die 102 and a punch 104, is provided. The matrix 102 and the punch 104 together define a chamber 106 for producing the mattress 10.

La chambre 106 est polygonale, ici hexagonale.The chamber 106 is polygonal, here hexagonal.

La matrice 102 définit une première paroi 108 de la chambre 106, et le poinçon 104 définit une deuxième paroi 110, opposée à la première paroi 108, de la chambre 106.The die 102 defines a first wall 108 of the chamber 106, and the punch 104 defines a second wall 110, opposite the first wall 108, of the chamber 106.

La première paroi 108 est sensiblement plane.The first wall 108 is substantially planar.

La deuxième paroi 110 comprend une surface plane 112, et une pluralité de nervures 114 (une seule de ces nervures 114 est représentée sur les Figures 8 et 9) faisant saillie depuis la surface plane 112 vers la matrice 102. La deuxième paroi 110 comprend également des bossages 116, dans chaque coin de la chambre 106.The second wall 110 comprises a flat surface 112, and a plurality of ribs 114 (only one of these ribs 114 is shown on the Figures 8 and 9 ) projecting from the flat surface 112 to the die 102. The second wall 110 also includes bosses 116, in each corner of the chamber 106.

La deuxième paroi 110 délimite ainsi des cavités 118 entre les nervures 114 et les bossages 116, la surface plane 112 forme le fond de chaque cavité 118.The second wall 110 thus defines cavities 118 between the ribs 114 and the bosses 116, the flat surface 112 forms the bottom of each cavity 118.

Les nervures 114 forment un motif correspondant à celui des articulations 16 du matelas 10. Avantageusement, comme représenté, les faces 120 de chaque nervure 114 forment un angle compris entre 40° et 50° avec la surface plane 112.The ribs 114 form a pattern corresponding to that of the joints 16 of the mattress 10. Advantageously, as shown, the faces 120 of each rib 114 form an angle between 40 ° and 50 ° with the flat surface 112.

Chaque bossage 116 présente une face plane 122 s'étendant sensiblement parallèlement à la surface plane 112, et un bord 124 de liaison de la face plane 122 à la surface plane 112. Le bord 124 est de préférence biseauté, comme représenté, et forme en particulier un angle compris entre 40 ° et 50 ° avec la surface plane 112.Each boss 116 has a planar face 122 extending substantially parallel to the planar surface 112, and a connecting edge 124 of the planar face 122 to the planar surface 112. The edge 124 is preferably beveled, as shown, and formed into particularly an angle between 40 ° and 50 ° with the flat surface 112.

Dans la variante de la Figure 9, correspondant au procédé de fabrication du matelas 10 selon la variante de la Figure 3, la face plane 122 de chaque bossage 116 et la pointe 126 de chaque nervure 114 sont à la même distance de la surface plane 112. En d'autres termes, chaque bossage 116 et chaque nervure 114 ont la même hauteur.In the variant of the Figure 9 corresponding to the process of manufacturing the mattress 10 according to the variant of Figure 3 , the flat face 122 of each boss 116 and the tip 126 of each rib 114 are at the same distance from the flat surface 112. In other words, each boss 116 and each rib 114 have the same height.

Dans la variante de la Figure 8, correspondant au procédé de fabrication du matelas 10 selon la variante de la Figure 2, chaque bossage 116 est plus haut que chaque nervure 114.In the variant of the Figure 8 corresponding to the process of manufacturing the mattress 10 according to the variant of Figure 2 each boss 116 is higher than each rib 114.

Lors d'une deuxième étape, une première grande feuille de tissu 130 est disposée dans le moule 100, contre la première paroi 108. La première grande feuille 130 est en matériau synthétique, avantageusement en polyester. Elle occupe toute la surface de la première paroi 108.In a second step, a first large sheet of fabric 130 is disposed in the mold 100, against the first wall 108. The first large sheet 130 is made of synthetic material, preferably polyester. It occupies the entire surface of the first wall 108.

Lors d'une troisième étape, au moins une plaque de mousse 132, 134 est disposée sur la première grande feuille 130, entre la première grande feuille 130 et le poinçon 104.In a third step, at least one foam plate 132, 134 is disposed on the first large sheet 130, between the first large sheet 130 and the punch 104.

Dans la variante de la Figure 8, une seule grande plaque de mousse 132 est disposée dans le moule 100. Une première grande face 136 de la plaque de mousse 132 est en appui contre la première grande feuille 130.In the variant of the Figure 8 a single large foam plate 132 is disposed in the mold 100. A first large face 136 of the foam plate 132 bears against the first large sheet 130.

La grande plaque de mousse 132 occupe sensiblement l'intégralité de la surface de la première grande feuille de tissu 130, à l'exception d'évidements 138 ménagés dans la plaque 132 au droit de chaque bossage 116.The large foam plate 132 occupies substantially the entire surface of the first large sheet of fabric 130, with the exception of recesses 138 in the plate 132 at the right of each boss 116.

La grande plaque 132 a une épaisseur sensiblement constante. Elle présente un bord périphérique 140 sensiblement perpendiculaire aux grandes faces 136, 142 de la grande plaque 132.The large plate 132 has a substantially constant thickness. It has a peripheral edge 140 substantially perpendicular to the large faces 136, 142 of the large plate 132.

Dans la variante de la Figure 9, une pluralité de plaques de mousse 134 sont disposées dans le moule 100. Chaque plaque de mousse 134 est disposée au droit d'une cavité 118 de la paroi 110, et présente une forme complémentaire à celle de ladite cavité 118.In the variant of the Figure 9 , a plurality of foam plates 134 are disposed in the mold 100. Each foam plate 134 is disposed in line with a cavity 118 of the wall 110, and has a shape complementary to that of said cavity 118.

Les plaques 134 sont espacées les unes des autres par des espaces 144, disposés au droit des nervures 114. En d'autres termes, aucune plaque 134 n'est en contact avec une autre plaque 134. Par ailleurs, aucune plaque 134 n'est disposée au droit d'un bossage 116.The plates 134 are spaced apart from each other by gaps 144 arranged in line with the ribs 114. In other words, no plate 134 is in contact with another plate 134. Moreover, no plate 134 is disposed at the right of a boss 116.

Chaque plaque 134 présente une première grande face 146 de contact avec la première grande feuille 130, et une deuxième grande face 148, opposée à la première grande face 146 et plus petite que cette dernière. Un bord périphérique 150 relie les deux grandes faces 146, 148 entre elles. Ce bord périphérique 150 est biseauté, et forme en particulier un angle compris entre 40° et 50° avec chaque grande face 146, 148.Each plate 134 has a first large face 146 of contact with the first large sheet 130, and a second large face 148, opposite to the first major face 146 and smaller than the latter. A peripheral edge 150 connects the two large faces 146, 148 to each other. This peripheral edge 150 is bevelled, and forms in particular an angle of between 40 ° and 50 ° with each major face 146, 148.

Puis, lors d'une quatrième étape, une deuxième grande feuille de tissu 152 est appliquée par-dessus la ou chaque plaque de mousse 132, 134, le long de la deuxième grande face 142, 148. La deuxième grande feuille de tissu 152 a la même forme que la première grande feuille de tissu 130.Then, in a fourth step, a second large sheet of tissue 152 is applied over the or each foam plate 132, 134, along the second major face 142, 148. The second large sheet of tissue 152 has the same shape as the first large sheet of fabric 130.

On notera que les vues des Figures 8 et 9 correspondent à une vue en coupe du moule 100 à l'issue de cette quatrième étape.It will be noted that the views of Figures 8 and 9 correspond to a sectional view of the mold 100 at the end of this fourth step.

Les grandes feuilles de tissu 130, 152 et la ou chaque plaque de mousse 132, 134 sont ensuite chauffées, puis le moule 100 est fermé.The large sheets of fabric 130, 152 and the or each foam plate 132, 134 are then heated, and then the mold 100 is closed.

En configuration fermée du moule 100, chaque bossage 116 presse la deuxième grande feuille 152 contre la première grande feuille 130. Sous l'effet de la chaleur et de la pression, celles-ci adhèrent l'une à l'autre, formant un volet 18 du matelas 10.In the closed configuration of the mold 100, each boss 116 presses the second large sheet 152 against the first large sheet 130. Under the effect of heat and pressure, they adhere to one another, forming a flap 18 of the mattress 10.

De plus, la surface plane 112 et la première paroi 108 prennent la première grande feuille 130, la ou chaque plaque de mousse 132, 134 et la deuxième grande feuille 152 en étau. Sous l'effet de la chaleur et de la pression, la première grande feuille 130 adhère à la première grande face 136, 146 de la ou chaque plaque 132, 134, et la deuxième grande feuille 152 adhère à la deuxième grande face 142, 148 de la ou chaque plaque 132, 134.In addition, the flat surface 112 and the first wall 108 take the first large sheet 130, the or each foam plate 132, 134 and the second large sheet 152 in a vice. Under the effect of heat and pressure, the first large sheet 130 adheres to the first large face 136, 146 of the or each plate 132, 134, and the second large sheet 152 adheres to the second major face 142, 148 of the or each plate 132, 134.

Par ailleurs, dans la variante de la Figure 8, chaque nervure 114 comprime la grande plaque de mousse 132 en pressant contre elle la deuxième grande feuille 152. L'épaisseur la grande plaque 132 est localement réduite, formant ainsi l'une des articulations 16 du matelas 10. De plus, sous l'effet de la chaleur et de la pression, la première grande feuille 130 adhère à la première grande face 136 de la plaque 132, et la deuxième grande feuille 152 adhère à la deuxième grande face 142 de la ou chaque plaque 132.Moreover, in the variant of Figure 8 , each rib 114 compresses the large foam plate 132 by pressing against it the second large sheet 152. The thickness of the large plate 132 is locally reduced, thus forming one of the joints 16 of the mattress 10. In addition, under the effect of heat and pressure, the first large sheet 130 adheres to the first large face 136 of the plate 132, and the second large sheet 152 adheres to the second large face 142 of the or each plate 132.

Dans la variante de la Figure 9, chaque nervure 114 presse la deuxième grande feuille 152 contre la première grande feuille 130, au niveau de l"un des espaces 144 entre les plaques 134. Sous l'effet de la chaleur et de la pression, les première et deuxième grandes feuilles 130, 152 adhèrent l'une à l'autre, formant une articulation 16 du matelas 10.In the variant of the Figure 9 each rib 114 presses the second large sheet 152 against the first large sheet 130, at one of the spaces 144 between the plates 134. Under the effect of heat and pressure, the first and second large sheets 130 152 adhere to each other, forming a hinge 16 of the mattress 10.

Le moule 100 est ensuite ouvert, et le matelas 10 est extrait du moule 100.The mold 100 is then opened, and the mattress 10 is extracted from the mold 100.

Pour finir, les organes d'attache 20, 22 sont fixés au matelas 10.Finally, the fastening members 20, 22 are fixed to the mattress 10.

Grâce à l'invention qui vient d'être décrite, les panneaux du matelas d'éveil et d'activité sont articulés les uns aux autres par des articulations sans couture. Cela permet d'avoir un matelas plus résistant, à l'espérance de vie augmentée par rapport aux matelas d'éveil et d'activité traditionnels.Thanks to the invention that has just been described, the panels of the awakening mat and activity are articulated to each other by seamless joints. This allows for a more resilient mattress, with increased life expectancy compared to traditional wake up and activity mattresses.

Il est en outre possible de réaliser des articulations très étroites pour ce matelas. Il en résulte une isolation et un confort du matelas accrus. La sécurité du matelas est également améliorée, puisque les risques pour qu'un enfant se coince dans les articulations sont réduits.It is also possible to achieve very narrow joints for this mattress. This results in increased insulation and mattress comfort. The safety of the mattress is also improved, since the risks for a child to get stuck in the joints are reduced.

De plus, le matelas présente un coût marginal réduit.In addition, the mattress has a reduced marginal cost.

Par ailleurs, les panneaux sont plus rigides, ce qui permet de conférer au matelas une meilleure tenue lorsque certains panneaux sont en saillie par rapport aux autres.In addition, the panels are more rigid, which allows to give the mattress a better hold when some panels are protruding from others.

Enfin, le matelas peut être disposé dans un très grand nombre de configurations, ce qui permet des utilisations variées du matelas.Finally, the mattress can be arranged in a very large number of configurations, which allows various uses of the mattress.

Pour finir, le matelas est très confortable, puisque l'absence de coutures entre les panneaux garantit un contact souple et doux, notamment avec la peau d'un enfant.Finally, the mattress is very comfortable, since the lack of seams between the panels ensures soft and soft contact, especially with the skin of a child.

On notera que l'invention n'est pas limitée à l'exemple particulier donné ci-dessus. En particulier, il a été décrit que toutes les articulations 16 du matelas 10 étaient sans couture. Or, dans une variante non préférée de l'invention, le matelas 10 est formé d'une pluralité de modules cousus les uns aux autres, chaque module comprenant plusieurs panneaux 12, 14 du matelas 10, articulés les uns aux autres par des articulations sans coutures formant certaines des articulations 16 du matelas 10, et les coutures formant les autres articulations 16 du matelas 10.It should be noted that the invention is not limited to the particular example given above. In particular, it has been described that all the joints 16 of the mattress 10 were seamless. However, in a non preferred variant of the invention, the mattress 10 is formed of a plurality of modules sewn to each other, each module comprising several panels 12, 14 of the mattress 10, articulated to each other by seamless joints forming some of the joints 16 of the mattress 10, and the seams forming the other joints 16 of the mattress 10.
