Description

  • La présente invention a pour objet un matelas à ressorts ensachés.
  • Les matelas à ressorts ensachés connus comportent, entre deux nappes de garnissage inférieure et supérieure, une nappe matricielle de ressorts ensachés d'axes sensiblement perpendiculaires aux nappes de garnissage.
  • La nappe matricielle de ressorts ensachés est constituée d'une pluralité de ressorts hélicoïdaux, chaque ressort hélicoïdal étant disposé à l'intérieur d'un sachet textile. Pour cela, une solution consiste à réaliser la nappe matricielle de ressorts à partir d'une bande de non-tissé repliée sur elle-même autour d'un pli transversal, puis cousue ou soudée transversalement pour former des compartiments ou sachets de réception des ressorts avant d'introduire les ressorts dans les compartiments et de fermer leurs ouvertures par couture ou soudage afin d'ensacher les ressorts.
  • Les bandes sont ensuite disposées les unes à côté des autres pour former la nappe matricielle, de manière que les ressorts ensachés présentent une disposition en quinconce ou en carrés, par exemple. En variante, les bandes peuvent également être disposées de manière croisée.
  • La présente invention a pour but de proposer un matelas à ressorts ensachés qui comporte un moyen d'aération efficace et qui soit moins sensible à un écrasement brutal du matelas.
  • A cet effet, l'invention a pour objet un matelas à ressorts ensachés comportant une nappe matricielle de ressorts destinée à être disposée entre une nappe inférieure et une nappe supérieure, ladite nappe matricielle de ressorts comportant un ensemble de sachets poreux aptes à être fixés les uns aux autres de manière que l'axe longitudinal de chaque sachet soit sensiblement perpendiculaire d'une part au plan de ladite nappe inférieure et d'autre part au plan de ladite nappe supérieure, chaque sachet étant apte à contenir un ressort hélicoïdal, caractérisé en ce chaque sachet comporte une ouverture d'aération, les dimensions de ladite ouverture d'aération étant nettement supérieures aux dimensions moyennes des pores dudit sachet.
  • Selon une forme particulière de réalisation de l'invention, ladite ouverture d'aération est sensiblement circulaire.
  • Avantageusement, ladite ouverture d'aération comporte un diamètre inférieur au diamètre dudit ressort hélicoïdal.
  • Selon une caractéristique de l'invention, ladite ouverture d'aération est disposée sur une paroi dudit sachet.
  • De préférence, ladite ouverture d'aération est disposée à proximité d'une extrémité dudit sachet.
  • L'invention sera mieux comprise, et d'autre buts, détails, caractéristiques et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative détaillée qui va suivre, d'un mode de réalisation de l'invention donné à titre d'exemple purement illustratif et non limitatif, en référence aux dessins schématiques annexés.
  • Sur ces dessins :
    • la figure 1 est une vue partielle, simplifiée et en perspective d'un matelas selon un mode de réalisation de l'invention ;
    • la figure 2 est une vue partielle, simplifiée et latérale d'une bande de sachets du matelas de la figure 1 ;
  • En se référant à la figure 1, on voit un matelas 1, comportant une nappe supérieure 2, une nappe inférieure 3 et, disposée entre les nappes 2 et 3, une nappe matricielle de ressorts 4. La nappe matricielle 4 comporte plusieurs bandes de sachets 5, 6, 7 et 8 disposées sensiblement parallèlement les unes par rapport aux autres. Les bandes 5, 6, 7 et 8 sont fixées les unes aux autres d'une manière connue en soi et qui ne sera pas décrite en détail ici.
  • On notera qu'il s'agit d'un exemple de réalisation, la disposition des bandes 5, 6, 7 et 8 les unes par rapport aux autres pouvant être quelconque. Les bandes pourraient par exemple être entrelacées.
  • Les nappes 2 et 3 sont par exemple constituées d'une toile textile, d'un feutre ou d'une plaque de mousse. La nappe supérieure 2 est fixée sur les faces supérieures des bandes 5, 6, 7 et 8 et la nappe inférieure 3 est fixée sur les faces inférieures des bandes 5, 6, 7 et 8, d'une manière connue en soi, par exemple par collage. Les nappes 2 et 3 participent ainsi à la solidarisation des bandes 5, 6, 7 et 8 entre elles.
  • La figure 2 montre de manière plus détaillée une partie de la bande 6. On notera que les bandes 5, 7 et 8 sont identiques à la bande 6. La bande 6 comporte quatre sachets 9, 10, 11 et 12, les sachets étant séparés les uns des autres par des coutures 13, 14 et 15 ou par tout autre moyen de séparation permettant de délimiter les sachets 9, 10, 11 et 12. Les coutures 13, 14 et 15 sont disposées de manière sensiblement perpendiculaire à l'axe longitudinal A de la bande 6.
  • Les sachets 9, 10, 11 et 12 ont une forme sensiblement cylindrique et sont réalisés dans une matière poreuse, par exemple en non-tissé. Chaque sachet 9, 10, 11 et 12 contient un ressort hélicoïdal 16, 17, 18 et 19. Les sachets sont fermés à leurs extrémités inférieure et supérieure, de manière que chaque ressort 16, 17, 18 et 19 se trouve enfermé dans un sachet 9, 10, 11 et 12 respectivement.
  • Chaque sachet 9, 10, 11 et 12 comporte une ouverture d'aération 20, 21, 22 et 23. Les ouvertures 20, 21, 22 et 23 sont de forme sensiblement circulaire. Le diamètre D de chaque ouverture 20, 21, 22 et 23 est inférieur au diamètre d'un ressort 16, 17, 18 ou 19, de manière que les ressorts ne puissent pas sortir des sachets 9, 10, 11 et 12 par les ouvertures. Le diamètre D est nettement supérieur aux dimensions moyennes des pores du sachet 9, 10, 11 et 12. Par exemple, le diamètre D est de l'ordre de quelques millimètres.
  • On va maintenant décrire le fonctionnement du matelas 1. Lorsque le matelas est écrasé de manière que les ressorts 16, 17, 18 et 19 soient comprimés, cela a pour effet une diminution du volume intérieur des sachets 9, 10, 11 et 12. A ce moment, du fait de la porosité des sachets 9, 10, 11 et 12, de l'air contenu dans les sachets 9, 10, 11 et 12 est expulsé par l'ensemble des pores présents sur les surfaces des sachets 9, 10, 11 et 12. Simultanément, l'air contenu dans les sachets 9, 10, 11 et 12 est expulsé vers l'extérieur des sachets 9, 10, 11 et 12 par les ouvertures 20, 21, 22 et 23. On notera que les pores d'un matériau non-tissé, de part leur nombre et leurs dimensions, ne permettent pas toujours une expulsion efficace de l'air, notamment lorsque l'écrasement est brutal, c'est-à-dire que la quantité d'air expulsée par les pores est très faible par rapport à la quantité d'air expulsée par les ouvertures 20, 21, 22 et 23. Les ouvertures 20, 21, 22 et 23 permettent donc de réduire fortement les contraintes mécaniques qui s'exercent sur les sachets 9, 10, 11 et 12 en assurant une expulsion efficace de l'air, c'est-à-dire en réduisant au maximum la compression de l'air à l'intérieur des sachets. La réduction des contraintes mécaniques peut par exemple permettre l'utilisation de matériaux moins résistants pour la réalisation des sachets, de manière à réduire les coûts de fabrication.
  • A ce moment, lorsque le matelas est relâché, les ressorts 16, 17, 18 et 19 ont tendance à se détendre de manière à reprendre leur position de repos, ce qui a pour effet une extension des sachets 9, 10, 11 et 12. De l'air est alors aspiré dans les sachets 9, 10, 11 et 12 à la fois par les pores et par les ouvertures 20, 21, 22 et 23. De la même manière que précédemment, l'air est principalement aspiré dans les sachets 9, 10, 11 et 12 par les ouvertures 20, 21, 22 et 23, les flux d'air permis par les pores étant très limités.
  • Les flux d'air générés par les ouvertures 20, 21, 22 et 23 entre les sachets 9, 10, 11 et 12 et l'extérieur lors des écrasements et des relâchements du matelas 1 étant conséquents, ils entraînent une aération efficace de l'intérieur des sachets 9, 10, 11 et 12. Cette aération permet une circulation optimale de l'air à l'intérieur du matelas.
  • D'autres variantes sont possibles, par exemple, la forme des ouvertures peut être quelconque, de même que leur position sur les sachets.
  • En outre, le nombre de sachets par bande peut également être quelconque.
  • Bien que l'invention ait été décrite en relation avec plusieurs modes de réalisations particuliers, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention.
