Description

La présente invention concerne les pièces de mobilier et plus particulièrement, une structure de mobilier à assemblage anti-bruit.The present invention relates to pieces of furniture and more particularly, a structure of furniture with anti-noise assembly.

Les pièces de mobilier modernes, par exemple les chaises, les escabeaux ou les échelles présentent,quel que soit le matériau constitutif des éléments de ces pièces de mobilier, des effets d'idiophone très marqués lors de l'entrechoquement de ces pièces de mobilier entre elles ou avec des structures fixes, comme on peut s'en rendre compte lors de l'installation de salles de spectacle ou de banquet, et surtout dans les établissements scolaires, plus particulièrement dans les maternelles. Tant pour des raisons esthétiques que de facilité d'entretien, les pièces de mobilier modernes sont fréquemment réalisées avec des éléments revêtus au moins partiellement d'un gainage, obtenu soit par dépôt d'un matériau de laquage ou par mise en place d'une gaine plastique thermorétractable. L'adjonction de ce genre de gaine, plaquée sur l'élément structurel, reste totalement dépendante de la configuration propre de cet élément structurel et ne réduit que dans une très faible mesure, voire pas du tout,les inconvénients des effets d'idiophone susmentionnés.Modern pieces of furniture, for example chairs, stepladders or ladders have, whatever the material of the elements of these pieces of furniture, very pronounced idiophone effects during the collision of these pieces of furniture between them or with fixed structures, as we can see when installing performance halls or banquets, and especially in schools, more particularly in kindergartens. Both for aesthetic reasons and for ease of maintenance, modern pieces of furniture are frequently made with elements at least partially covered with a coating, obtained either by depositing a lacquering material or by placing a heat shrinkable plastic sheath. The addition of this kind of sheath, pressed against the structural element, remains totally dependent on the specific configuration of this structural element and only reduces to a very small extent, if at all, the drawbacks of the aforementioned idiophone effects .

La présente invention a précisément pour objet une structure de mobilier a caractéristiques anti-bruit permettant d'obvier à ces inconvénients, en proposant une structure constituée de l'assemblage d'un élément structurel et d'un élément de gainage, agencé autour de cet élément structurel offrant, sans modification des coûts et sans diminution de tenue mécanique, un amortissement phonique remarquable contre les effets d'idiophone et une réduction sensible du poids de la structure.The object of the present invention is precisely a furniture structure with anti-noise characteristics allowing to overcome these drawbacks, by proposing a structure consisting of the assembly of a structural element and a sheathing element, arranged around this structural element offering, without modifying costs and without reduction in mechanical strength, remarkable sound absorption against the effects of idio p hone and a significant reduction in the weight of the structure.

La présente invention a pour autre objet une structure de mobilier de ce type offrant une grande souplesse d'utilisation en rendant, notamment, l'aspect-extérieur de la structure de mobilier, conféré par les éléments de gainage, relativement indépendante de la structure propre des éléments structurels, tracteurs ou porteurs, réalisant l'ossature porteuse d'une pièce de mobilier.Another object of the present invention is a furniture structure of this type offering great flexibility of use by making, in particular, the external appearance of the furniture structure, conferred by the sheathing elements, relatively independent of the structure proper structural elements, tractors or carriers, providing the supporting framework for a piece of furniture.

Pour ce faire, selon une caractéristique de la présente invention, les éléments structurels et de gainage, de forme allongée, sont conformés et positionnés l'un par rapport à l'autre de façon qu'un espacement formant coussin d'amortissement soit ménagé sur la majeure partie de l'interface entre les éléments.To do this, according to a characteristic of the present invention, the structural and sheathing elements, of elongated shape, are shaped and positioned relative to each other so that a space forming a cushioning cushion is provided on most of the interface between the elements.

Selon une caractéristique plus particulière de l'invention les éléments présentent en coupe transversale des sections relatives telles qu'en position assemblée, un jeu soit ménagé sur la majeure partie dé la périphérie de l'élément structurel entre celle-ci et le profil interne du second élément.According to a more particular characteristic of the invention, the elements have in cross section relative sections such that in the assembled position, a clearance is provided over the major part of the periphery of the structural element between the latter and the internal profile of the second element.

Dans un mode de réalisation plus particulier, l'élément structurel, avantageusement en bois, est rainuré longitudinalement sur toute sa longueur, le profil exinscrit aux nervures délimitant les rainures correspondant en valeur inférieure au profil intérieur de l'élément de gainage, réalisé avantageusement en matière plastique, par exemple colorée.In a more particular embodiment, the structural element, advantageously of wood, is grooved longitudinally over its entire length, the profile exinscribed to the ribs delimiting the grooves corresponding in value less than the internal profile of the sheathing element, advantageously made of plastic material, for example colored.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description suivante de modes de réalisation, donnés à titre illustratif mais nullement limitatif, faite en relation avec les dessins annexés sur lesquels :

  • . La figure 1 représente un mode de réalisation d'une structure de mobilier utilisant les éléments de mobilier selon la présente invention;
  • La figure 2 est une coupe transversale suivant le plan A-A du barreau de la figure 1;
  • La figure 3 est une vue en coupe transversale d'un autre mode de réalisation d'un tel barreau; et
  • La figure 4 représente d'autres variantes de réalisation d'une structure de mobilier selon la présente invention.
Other characteristics and advantages of the present invention will emerge from the following description of embodiments, given by way of illustration but not limitative, made in relation to the accompanying drawings in which:
  • . Figure 1 shows an embodiment of a furniture structure using the furniture elements according to the present invention;
  • Figure 2 is a cross section along the plane AA of the bar of Figure 1;
  • Figure 3 is a cross-sectional view of another embodiment of such a bar; and
  • Figure 4 shows other alternative embodiments of a furniture structure according to the present invention.

On a représenté schématiquement sur la figure l,une structure de mobilier du type échelle pouvant également constituer une partie du piètement d'une chaise, et comprenant un barreau 1 reliant deux montants 2 et 3. Sur la figure 1, le montant de droite 2 est du type connu avec une âme lisse 4, revêtue d'une gaine en matière plastique 5, par exemple, thermorétractable.There is shown diagrammatically in FIG. 1, a ladder-type furniture structure which can also constitute part of the base of a chair, and comprising a bar 1 connecting two uprights 2 and 3. In FIG. 1, the upright on the right 2 is of the known type with a smooth core 4, coated with a plastic sheath 5, for example, heat shrinkable.

Le barreau 1 selon la présente invention, également représenté sur la figure 2, comprend un premier élément structurel où âme 6, de forme cylindrique, avantageusement en bois et formé, sur sa périphérie, avec des rainures 7, obtenues par exemple par des mors lors de la conformation du barreau 6. Le cercle exinscrit aux nervures 8 saillant entre les rainures 7 correspond en valeur légèrement inférieure au diamètre interne de la gaine rigide ou semi-rigide 9, réalisée par exemple en acrylonitrile-butadiène-styrène ou en polyéthylène à haute densité, emmanchée sur le premier élément 6. On conçoit que, avec cet agencement, les zones de contact entre l'âme 6 et la gaine 9 se réduisent aux minces génératrices des nervures 8, de sorte que, un choc étant appliqué sur le barreau 1, seule une très faible partie de l'onde de pression est transmise à l'âme massive 6, en réalisant ainsi un effet d'idiophone réduit d'au moins 20 dB par rapport à celui qui est réalisé par le montant conventionnel 2. En effet, cet agencement ménage, entre la surface périphérique de l'âme 6 et la paroi interne de la gaine 9, un coussin d'air, plus particulièrement visible sur la figure 1, constitué par l'ensemble des rainures 7, et occupant la majeure partie de l'interface entre l'âme 6 et la gaine 9.The bar 1 according to the present invention, also shown in FIG. 2, comprises a first structural element where core 6, of cylindrical shape, advantageously of wood and formed, on its periphery, with grooves 7, obtained for example by jaws during of the conformation of the bar 6. The circle exinscribed to the ribs 8 projecting between the grooves 7 corresponds in value slightly less than the internal diameter of the rigid or semi-rigid sheath 9, made for example of acrylonitrile-butadiene-styrene or high-density polyethylene density, fitted on the first element 6. It is understood that, with this arrangement, the contact zones between the core 6 and the sheath 9 are reduced to the thin generators of the ribs 8, so that, a shock being applied to the bar 1, only a very small part of the pressure wave is transmitted to the massive core 6, thus achieving an idiophone effect reduced by at least 20 dB compared to that which is achieved by the conventional upright 2. Indeed, this arrangement household, between the on peripheral face of the core 6 and the internal wall of the sheath 9, an air cushion, more particularly visible in FIG. 1, constituted by all of the grooves 7, and occupying most of the interface between the core 6 and sheath 9.

Sur le montage de la figure 1, le barreau 1 est logé par ses extrémités dans des évidements étagés des montants 2 et 3, ces évidements étagés comprenant un alésage central plus profond 10, pour recevoir l'extrémité de l'âme 6, et un alésage coaxial moins profond 11 pour recevoir l'extrémité de la gaine 9, 1a gaine 5 du montant présentant bien sûr une découpe analogue à l'alésage moins profond 11. Le même type de montage est adopté sur le montant gauche 3 de la figure 1, réalisé toutefois conformément à la présente invention, avec une âme 4' cylindrique lisse de diamètre externe inférieur au diamètre interne de la gaine 5' en matière plastique rigide, le positionnement relatif de ces deux éléments étant assuré, pour maintenir entre eux, sur la quasi-totalité de l'interface, un coussin d'air en forme de couronne cylindrique 12, soit par un embout en forme de capuchon 13 présentant des évidements étagés 10' et 11' à la manière des évidements du barreau 2, soit, en bout, en prévoyant une extrémité de diamètre élargi cannelée ou rainurée 14, de l'âme 4', dans un mode de réalisation analogue à celui représenté sur la figure .2. Il va sans dire, que le montant 3 peut comporter également une âme 4' entièrement rainurée à la façon du barreau 1, le capuchon d'embout 13 étant alors réalisé simplement sous la forme d'une coiffe de protection.In the assembly of FIG. 1, the bar 1 is housed at its ends in stepped recesses of the uprights 2 and 3, these stepped recesses comprising a deeper central bore 10, to receive the end of the core 6, and a shallower coaxial bore 11 for receiving the end of the sheath 9, the sheath 5 of the upright of course having a cutout analogous to the shallower bore 11. The same type of mounting is adopted on the left upright 3 of FIG. 1 , however produced in accordance with the present invention, with a smooth cylindrical core 4 ′ with an external diameter less than the internal diameter of the sheath 5 ′ in rigid plastic material, the relative positioning of these two elements being ensured, in order to maintain them on the almost all of the interface, an air cushion in the form of a cylindrical crown 12, either by a cap-shaped endpiece 13 having stepped recesses 10 'and 11' in the manner of the recesses of the bar 2, or, tip, providing for an e x end of enlarged grooved or grooved diameter 14, of the core 4 ′, in an embodiment similar to that shown in FIG. 2. It goes without saying, that the upright 3 can also include a core 4 'entirely grooved in the manner of the bar 1, the end cap 13 then being produced simply in the form of a protective cap.

Dans le mode de réalisation du montant gauche 3, l'âme 4',a une section homothétique de la gaine cylindrique 5' mais, comme représenté sur la figure 3, l'âme 40 peut avoir une section polygonale, inscriptible dans le cercle du diamètre interne de la gaine 12, de façon à ne porter, en étant ainsi centrée contre cette dernière que par les arêtes 15 du polygone, en ménageant entre ses arêtes des coussins d'air 16, occupant plus de 95 % de l'interface entre l'élément structurel et sa gaine.In the embodiment of the left upright 3, the core 4 ′ has a homothetic section of the cylindrical sheath 5 ′ but, as shown in FIG. 3, the core 40 may have a polygonal section, inscribable in the circle of the internal diameter of the sheath 12, so as to bear, thus being centered against the latter only by the edges 15 of the polygon, by providing between its edges air cushions 16, occupying more than 95% of the interface between the structural element and its sheath.

On a représenté sur la figure 4, un développement ultérieur des modes de réalisation du montant gauche 3 de la figure 1. Dans ce mode de réalisation, l'âme 41, réalisée par exemple sous la forme d'un tube ou d'un profilé métallique, présente un diamètre ou , plus généralement, un profil extérieur de dimensions notablement plus réduites que le profil intérieur de la gaine 120, cylindrique ou prismatique.Le positionnement relatif des deux éléments 41 et 120 est obtenu par des moyens de liaison 42, 43 reliant transversalement les deux éléments en s'étendant au travers du vaste espacement 44 isolant phoniquement l'âme 41 de la gaine 120. Sur la partie gauche de la figure 4, les moyens de liaison sont réalisés par des ailettes radiales 42, saillant vers l'intérieur de la gaine 120, pour former une portée d'appui 45 pour l'âme 41, la structure de mobilier représentée sur la figure 4 étant obturée en bout par un simple capuchon 130. Sur la partie droite de la figure 4, les moyens de liaison sont réalisés par des entretoises 43,par exemple en matériau plastique ou caoutchouc dur, emmanchées sur l'âme 41, la gaine 120 étant à son tour emmanchée sur ces entretoises 43. Comme à la partie supérieure du montant 3 de la figure l,le positionnement relatif de l'âme 41 et de la gaine 120 peut être assuré en bout par un capuchon 13' présentant des évidements concentriques pour recevoir les extrémités de la gaine et de l'âme.There is shown in Figure 4, a further development of the embodiments of the left upright 3 of Figure 1. In this embodiment, the core 41, produced for example in the form of a tube or a profile metallic, has a diameter or, more generally, an outer profile of dimensions considerably smaller than the inner profile of the sheath 120, cylindrical or prismatic. The relative positioning of the two elements 41 and 120 is obtained by connecting means 42, 43 transversely connecting the two elements, extending across the large space 44 phonic isolating the core 41 from the sheath 120. On the left side of FIG. 4, the connection means are produced by radial fins 42, projecting towards the inside the sheath 120, to form a bearing surface 45 for the core 41, the furniture structure shown in FIG. 4 being closed at the end by a simple cap 130. On the right part of FIG. 4, the connecting means have been made by spacers 43, for example of plastic material or hard rubber, fitted on the core 41, the sheath 120 being in turn fitted on these spacers 43. As in the upper part of the upright 3 of Figure l, the relative positioning of the core 41 and the sheath 120 can be ensured at the end by a cap 13 ′ having concentric recesses for receiving the ends of the sheath and of the core.

Le mode de réalisation avec une âme nervurée représenté sur les figures 1 et 2 présente en outre un avantage marquant en ce qui concerne la solidarisation entre le barreau 1 et les montants 2 et 3 dans la mesure où les rainures 7 permettent un refoulement et une bonne répartition de la colle disposée dans le fond de l'alésage 10 préalablement à l'emmanchement du barreau dans le montant.The embodiment with a ribbed core shown in Figures 1 and 2 also has a significant advantage with regard to the connection between the bar 1 and the uprights 2 and 3 insofar as the grooves 7 allow a backflow and good distribution of the adhesive disposed in the bottom of the bore 10 prior to the fitting of the bar into the upright.

Quoique la présente invention ait été décrite en relation avec des modes de réalisation particuliers, elle ne s'en trouve pas limitée mais est au contraire susceptible de modifications et de variantes qui apparaîtront à l'homme de l'art. En particulier, suivant les cas d'espèce, les espacements ou jeux entre l'âme et la gaine peuvent être, au moins localement, remplis d'une matière de bourrage divisée ou multicellulaire augmentant les qualités d'amortissement phonique et également la tenue mécanique de la pièce de mobilier.Although the present invention has been described in relation to particular embodiments, it is not limited thereto but is on the contrary subject to modifications and variants which will appear to those skilled in the art. In particular, depending on the case, the es pitches or clearances between the core and the sheath can be, at least locally, filled with a divided or multicellular stuffing material increasing the sound absorption qualities and also the mechanical strength of the piece of furniture.
