Abstract
Description
La présente invention concerne un bloc de garniture, notamment utilisé pour le rembourrage de matelas ou de coussins. The present invention relates to a lining block, in particular used for stuffing mattresses or cushions.
Les blocs de garniture habituellement utilisés, en mousse de latex ou de polyéther, se rencontrent sous une forme compacte, ou ajouree par la présence d'alvéoles. The packing blocks usually used, made of latex foam or polyether, meet in a compact form, or perforated by the presence of cells.
Dans le cas des blocs alvéolés, c'est-a-dire munis de cavités verticales cylindriques debouchantes ou borgnes, pour les rendre plus souples, on observe que la mousse ne travaille pas dans de bonnes conditions lorsque la densité d'alvéoles est importante. En effet, les parois verticales en mousse, qui délimitent les alvéoles sont minces et fragiles ; elles ont tendance à se de former dans tous les sens lorsqu'elles sont soumises a une compression, et à se détériorer rapidement surtout au niveau de la face d'appui. In the case of honeycombed blocks, that is to say provided with vertical cylindrical cavities emerging or blind, to make them more flexible, it is observed that the foam does not work in good conditions when the density of cells is high. In fact, the vertical foam walls which delimit the cells are thin and fragile; they tend to form in all directions when they are subjected to compression, and to deteriorate quickly especially at the level of the bearing face.
Les blocs sans alveoles ou avec des alvéoles mais en faible densité, sont nettement moins souples mais ils ont une meilleure tenue à la compression ; ils présentent notamment l'inconvénient de résister à toute forme de pliage, ce qui les rend quasiment incompatibles avec certains types de sommiers comme les sommiers brisés. The blocks without cells or with cells but in low density, are much less flexible but they have better resistance to compression; in particular, they have the drawback of resisting any form of folding, which makes them almost incompatible with certain types of box springs such as broken bed bases.
La présente invention vise à remédier à ces incon vénients en proposant un bloc qui présente à la fois les qualités de souplesse d'un bloc fortement alvéolé permettant notamment son pliage, et les qualités de bonne résistance d'un bloc compact, ou très faiblement alvéolé. The present invention aims to remedy these drawbacks by proposing a block which has both the flexibility qualities of a highly honeycombed block allowing it to be folded in particular, and the qualities of good resistance of a compact block, or very slightly honeycombed block. .
Selon l'invention, le bloc de mousse comporte, au moins sur une face d'appui, des rainures s'étendant sur toute la largeur du bloc et dont la section est en forme de fer à cheval, ou de U à branches concourantes. According to the invention, the foam block comprises, at least on one bearing face, grooves extending over the entire width of the block and whose section is in the shape of a horseshoe, or of a U with concurrent branches.
Selon une autre disposition de l'invention la largeur de la bande de mousse constituant la surface d'appui, entre deux rainures, est choisie en fonction de la densité de la mousse, pour offrir une nervosité correspondant à la destination du bloc. According to another arrangement of the invention, the width of the strip of foam constituting the bearing surface, between two grooves, is chosen as a function of the density of the foam, in order to offer a nervousness corresponding to the destination of the block.
Toujours selon l'invention, le bloc comporte, sur au moins une de ses faces d'appui, des rainures transversales et des rainures longitudinales formant des surfaces élémentaires d'appui, carrées. Still according to the invention, the block comprises, on at least one of its support faces, transverse grooves and longitudinal grooves forming elementary support surfaces, square.
Selon une autre disposition de l'invention, la profondeur des rainures est sensiblement comprise entre la moitié et les deux tiers de l'épaisseur du bloc. According to another arrangement of the invention, the depth of the grooves is substantially between half and two thirds of the thickness of the block.
Selon une autre disposition de l'invention, pour un meme bloc et selon sa destination, la profondeur des rainures et leur espacement sont réguliers ou variables dans certaines zones qui nécessitent une résistance différente. According to another arrangement of the invention, for the same block and according to its destination, the depth of the grooves and their spacing are regular or variable in certain zones which require different resistance.
Selon une autre disposition de l'invention, le bloc comporte sur la face opposée aux rainures, des petites alvéoles d'aération, régulièrement espacées et disposées dans les parties compactes du bloc, c'est-à-dire a l'opposé des surfaces élémentaires d'appui. According to another arrangement of the invention, the block comprises on the face opposite the grooves, small ventilation cells, regularly spaced and arranged in the compact parts of the block, that is to say opposite the surfaces elementary support.
Toujours selon l'invention et notamment pour la confection de matelas, le bloc rainuré peut être associé à un bloc compact de façon à obturer les rainures, ou encore etre associé à un autre bloc rainuré en juxtaposant les surfaces élémentaires d'appui, qu'elles soient en bandes ou en carres. Still according to the invention and in particular for making mattresses, the grooved block can be associated with a compact block so as to close the grooves, or even be associated with another grooved block by juxtaposing the elementary bearing surfaces, that they are in bands or in squares.
L'invention sera mieux comprise à l'aide de la description suivante et des dessins annexés donnés à titre indicatif et dans lesquels - la figure 1 présente une portion de bloc alvéolé tel qu'on le rencontre actuellement, - la figure 2 présente une portion d'un bloc rainuré selon l'invention, - la figure 3 présente une autre possibilité de l'invention, - la figure 4 présente une composition réalisée avec un bloc ordinaire compact et un bloc selon l'invention, - la figure 5 pressente une composition réalisée au moyen de deux blocs selon l'invention. The invention will be better understood with the aid of the following description and of the appended drawings given by way of indication and in which - FIG. 1 presents a portion of a honeycomb block as it is currently encountered, - FIG. 2 presents a portion of a grooved block according to the invention, - Figure 3 shows another possibility of the invention, - Figure 4 shows a composition made with an ordinary compact block and a block according to the invention, - Figure 5 presents a composition produced by means of two blocks according to the invention.
La figure 1 présente une portion de bloc classique, coupé, qui comporte des alvéoles 1 en forme de cavités verticales cylindriques borgnes, ouvertes du côté de la face inférieure sur la figure. Les parois 2 de mousse, qui délimitent ces alvéoles 1 ont une epaisseur variable mais qui est relativement mince surtout lorsque la densité d'alvéoles est importante. Figure 1 shows a portion of a conventional block, cut, which has cells 1 in the form of vertical cylindrical blind cavities, open on the side of the lower face in the figure. The walls 2 of foam, which delimit these cells 1 have a variable thickness but which is relatively thin especially when the density of cells is high.
De ce fait, dans les zones minces, la mousse s'écrase et se déforme fortement sans offrir une quelconque resistance. Therefore, in thin areas, the foam crushes and deforms strongly without offering any resistance.
La figure 2 présente une portion de bloc selon l'invention. Le bloc cornporte des rainures 3, qui s'etendent sur toute sa largeur. Figure 2 shows a block portion according to the invention. The block includes grooves 3, which extend over its entire width.
Ces rainures 3 ont une section en forme de fer à cheval, ou de U à branches convergentes ; leur profondeur peut varier selon la souplesse souhaitée et selon l'épaisseur du bloc entre, par exemple, la moitié et les deux tiers de l'épaisseur du bloc ; leur largeur maximale est de préference inferieure ou égale à l'épaisseur minimale de matiere qui les sépare, et leur ouverture, au niveau de la face 4 inférieure du bloc, est par exemple de la moitie jusqu'au quart de la largeur de la bande de mousse 5 au niveau de ladite face inférieure. These grooves 3 have a section in the shape of a horseshoe, or of a U with converging branches; their depth can vary according to the flexibility desired and according to the thickness of the block between, for example, half and two thirds of the thickness of the block; their maximum width is preferably less than or equal to the minimum thickness of material which separates them, and their opening, at the level of the lower face 4 of the block, is for example from half to a quarter of the width of the strip foam 5 at said lower face.
La largeur des bandes 5 est fonction de la densité de la mousse utilisée, et, selon cette densité elle est choisie pour que la bande de mousse conserve une bonne nervosité, c'est-à-dire une bonne resistance, et ne s'écrase pas au point d'être détériorée. The width of the strips 5 depends on the density of the foam used, and, according to this density, it is chosen so that the strip of foam retains a good nervousness, that is to say a good resistance, and does not crush not to the point of deterioration.
La face 4 constituant la face d'appui, se présente sous la forme d'une série de bandes élémentaires 5 rectangulaires, allongées sur toute la largeur du bloc, et espacées les unes par rapport aux autres. The face 4 constituting the bearing face is in the form of a series of elementary rectangular strips 5, elongated over the entire width of the block, and spaced apart from one another.
L'espacement des bandes 5 peut être régulier pour tout le bloc ou variable pour réaliser des zones plus résistantes ou plus souples ; c'est-a-dire què dans certaines zones les rainures seront faiblement écartées les unes. des autres, alors que dans d'autres zones moins chargées par exemple, elles seront plus écartées les unes des autres. The spacing of the bands 5 can be regular for the whole block or variable to produce more resistant or more flexible zones; that is to say that in certain areas the grooves will be slightly spaced apart. from others, while in other less loaded areas for example, they will be further apart from each other.
On peut également faire varier la profondeur des rainures pour modifier la résistance du bloc dans certaines zones plus ou moins chargées. The depth of the grooves can also be varied to modify the resistance of the block in certain more or less loaded areas.
La figure 3 présente une variante de réalisation de l'invention dans laquelle le bloc comporte a la fois des rainures transversales 3 et des rainures longitudinales 3a. Figure 3 shows an alternative embodiment of the invention in which the block has both transverse grooves 3 and longitudinal grooves 3a.
Les surfaces d'appui élémentaires se présentent sous la forme de carrés 6 ; on peut toutefois obtenir localement, des surfaces élémentaires différentes selon l'espacement choisi entre les rainures dans certaines zones du bloc en fonction par exemple, de la charge destinée à ces zones.The elementary bearing surfaces are in the form of squares 6; however, it is possible to locally obtain different elementary surfaces according to the spacing chosen between the grooves in certain zones of the block depending for example on the load intended for these zones.
La figure 4 présente une composition réalisée au moyen d'un bloc rainuré 7 et d'un bloc compact ordinaire 8 de faible épaisseur. Le bloc compact 8 obture les rainures 3 et procure une surface d'appui 9, continue. FIG. 4 shows a composition produced by means of a grooved block 7 and an ordinary compact block 8 of small thickness. The compact block 8 closes the grooves 3 and provides a continuous support surface 9.
On remarque également, sur la figure 4, des petites alvéoles 10 disposées dans le bloc, qui débouchent sur la face 11 oppOsée à celle des rainures 3 ; ces alvéoles constituent un système d'aération qui évite la condensation et la concentration de l'humidité. Ces alvéoles 10 se présentent sous la forme de cavités cylindriques verticales régulièrement espacées et disposées dans la partie compacte du bloc, à l'oppose des bandes 5 ou des carrés 6 servant d'appui. We also note, in Figure 4, small cells 10 disposed in the block, which open on the face 11 oppOsée to that of the grooves 3; these cells constitute an aeration system which prevents condensation and the concentration of moisture. These cells 10 are in the form of vertical cylindrical cavities regularly spaced and arranged in the compact part of the block, opposite the strips 5 or squares 6 serving as support.
La figure 5 présente une autre composition réalisée au moyen de deux blocs rainurés 7 et 7b. Les rainures 3 et 3b sont mises en face les unes des autres ainsi que les surfaces d'appui élémentaires de chaque bloc. FIG. 5 shows another composition produced by means of two grooved blocks 7 and 7b. The grooves 3 and 3b are placed opposite one another as well as the elementary bearing surfaces of each block.
I1 va de soi que l'invention ne se limite pas aux exemples de réalisation décrits, mais qu'elle embrasse également les variantes compatibles avec chacune des revendications annexées. It goes without saying that the invention is not limited to the embodiments described, but that it also embraces the variants compatible with each of the appended claims.
