Description

La présente invention a trait au domaine général de la literie. Elle concerne en particulier le domaine des carcasses de type à ressorts pour matelas.The present invention relates to the general field of bedding. It relates in particular to the field of spring-type carcasses for mattresses.

Les carcasses de ce genre comportent de manière classique une pluralité de ressorts métalliques configurés en spirale, qui sont fortement liaisonnés les uns aux autres pour conférer une bonne cohésion et une bonne solidité à la structure.Carcasses of this type typically include a plurality of spiral-shaped metal springs, which are strongly bonded to each other to provide good cohesion and strength to the structure.

Les ressorts en question sont dans certains cas assemblés par de multiples liens métalliques ; dans d'autres cas, ils sont ensachés individuellement dans des poches textiles, solidarisées les unes aux autres par exemple par collage ou couture.The springs in question are in some cases assembled by multiple metal links; in other cases, they are individually bagged in textile pockets, secured to each other for example by gluing or sewing.

Cependant, ces liaisons métalliques des ressorts, ou leur mise en poche, compliquent la mécanisation des opérations de montage des carcasses, et également les opérations de démontage pour le recyclage des matériaux.However, these metal connections springs, or their pocket, complicate the mechanization of carcass mounting operations, and also disassembly operations for recycling materials.

Par le document US-2 287 226 on sait réaliser une carcasse de matelas au moyen de ressorts spirales métalliques fixés sur un tissu souple support au moyen d'agrafes munies de crochets ; là encore cette solution technique n'apparaît pas satisfaisante du fait de sa complexité de mise en oeuvre.By the document U.S. 2,287,226 it is known to make a mattress carcass by means of metal spiral springs fixed on a flexible support fabric by means of hooked clips; again this technical solution does not appear satisfactory because of its complexity of implementation.

De plus, bien souvent, les carcasses obtenues ne sont pas bien adaptées pour être intégrées dans des matelas destinés à équiper des sommiers articulés, car elles sont trop rigides.In addition, the carcasses obtained are often not well adapted to be integrated into mattresses intended to equip articulated bed bases, because they are too rigid.

La présente invention vise à remédier à ces inconvénients en proposant une carcasse à ressorts de structure originale simplifiée, dont le montage et le démontage s'effectuent très facilement, sans nécessiter de moyens mécaniques complexes et onéreux. Cette carcasse est également très facilement totalement recyclable, et certaines de ses réalisations particulières sont bien adaptées pour être intégrées dans les matelas équipant les sommiers articulés.The present invention aims to remedy these drawbacks by proposing a spring casing of simplified original structure, the mounting and dismounting are very easy, without requiring complex and expensive mechanical means. This carcass is also very easily recyclable, and some of its particular achievements are well suited to be integrated into the mattress equipping the articulated bed bases.

Les buts ci-dessus sont atteints par une carcasse comprenant une feuille support, réalisée en matériau souple ou semi-rigide, sur l'une au moins des faces de laquelle sont fixés une pluralité d'organes ressorts ; ces organes ressorts comportent chacun une embase, disposée au niveau d'un orifice de réception aménagé dans la feuille support, et coopérant, par le biais de moyens de fixation appropriés, avec un élément de maintien rapporté sur l'autre face de ladite feuille support.
Les organes ressorts et les éléments de maintien (qui peuvent être également des organes ressorts) se maintiennent mutuellement et sont portés par la feuille support.The above objects are achieved by a carcass comprising a support sheet, made of flexible or semi-rigid material, on at least one of the faces of which are fixed a plurality of spring members; these spring members each comprise a base, disposed at a receiving orifice formed in the support sheet, and cooperating, by means of appropriate fixing means, with a holding element attached to the other side of said support sheet .
The spring members and the holding members (which may also be spring members) hold each other and are carried by the support sheet.

Selon une forme particulièrement intéressante de réalisation, les moyens de' fixation des organes ressorts et des éléments de maintien associés sont amovibles, en particulier pour faciliter le démontage de la structure ; ces moyens de fixation peuvent être de type encliquetage ou autre.According to a particularly advantageous embodiment, the means for fixing the spring members and the associated holding elements are removable, particularly to facilitate dismantling of the structure; these fixing means may be snap type or other.

Selon une forme de réalisation préférée, les organes ressorts et les éléments de maintien associés comportent des moyens de fixation amovibles constitués d'un tenon, muni d'ergots saillants de blocage à son extrémité libre, aménagé sur l'un des éléments (organe ressort ou élément de maintien), coopérant avec un orifice formant mortaise, aménagé sur l'autre élément (selon le cas un organe ressort ou un élément de maintien).According to a preferred embodiment, the spring members and the associated holding elements comprise removable fixing means consisting of a tenon, provided with locking projections protruding at its free end, arranged on one of the elements (spring member or holding element), cooperating with a hole forming a mortise, arranged on the other element (as appropriate a spring member or a holding element).

Selon encore une disposition particulière de l'invention, l'embase des organes ressorts et les moyens de maintien associés comportent chacun une surface plane qui s'étend en regard de l'une des faces de la feuille support, au niveau du pourtour de l'orifice de réception.According to another particular embodiment of the invention, the base of the spring members and the associated holding means each comprise a flat surface which extends facing one of the faces of the support sheet, at the periphery of the receiving orifice.

Dans une forme de réalisation particulièrement avantageuse, la carcasse comprend des premiers organes ressorts aménagés sur l'une des faces de la feuille support, et des seconds organes ressorts agencés sur l'autre face de ladite feuille support, en regard desdits premiers organes ressorts ; chacun des premiers organes ressorts est solidarisé avec l'un des seconds organes ressorts, au niveau d'un orifice de réception aménagé dans la feuille support, formant ainsi des couples d'organes ressorts disposés de part et d'autre de ladite feuille support, l'embase de l'un des organes ressorts dudit couple constituant l'élément de maintien de l'autre organe ressort de ce couple.In a particularly advantageous embodiment, the carcass comprises first spring members arranged on one of the faces of the support sheet, and second spring members arranged on the other side of said support sheet, facing said first spring members; each of the first spring members is secured to one of the second spring members, at a receiving orifice formed in the support sheet, thus forming pairs of spring members disposed on either side of said support sheet, the base of one of the spring members of said pair constituting the holding member of the other member spring from this pair.

Selon une disposition particulière de cette forme de réalisation, les premiers et seconds organes ressorts sont de forme générale identique ou similaire.According to a particular arrangement of this embodiment, the first and second spring members are of generally identical or similar shape.

Selon encore une disposition particulière, les couples de ressorts comportent un conduit ou canal traversant l'orifice de réception de la feuille support, en vue d'assurer l'aération du matelas.According to another particular provision, the couples of springs comprise a duct or channel passing through the receiving orifice of the support sheet, in order to ensure aeration of the mattress.

Toujours selon une disposition particulière, présentant un intérêt dans le cadre de l'équipement de sommiers articulés, la carcasse conforme à l'invention comporte une feuille support agencée dans son plan médian ou sensiblement médian.Still according to a particular provision, having an interest in the context of the equipment of articulated bed bases, the carcass according to the invention comprises a support sheet arranged in its median or substantially median plane.

Dans une forme de réalisation particulière, les organes ressorts comprennent chacun - une embase apte à coopérer avec un élément de maintien rapporté sur l'autre face de la feuille support, par le biais de moyens de fixation amovibles, et - un plateau destiné à former une surface de contact avec l'une des couches de matière de rembourrage du matelas ; cette embase et ce plateau sont raccordés par des moyens de suspension, constitués avantageusement d'au moins une lame déformable.In a particular embodiment, the spring members each comprise a base adapted to cooperate with a holding element attached to the other face of the support sheet, by means of removable fixing means, and a plate intended to form a contact surface with one of the padding material layers of the mattress; this base and this plate are connected by suspension means, advantageously constituted by at least one deformable blade.

Encore selon une disposition particulière de l'invention, les organes ressorts sont réalisés en matériau thermoplastique.Still according to a particular embodiment of the invention, the spring members are made of thermoplastic material.

L'invention concerne également un organe ressort en matériau thermoplastique pour une carcasse de matelas telle que définie ci-dessus, comprenant une embase apte à coopérer avec un élément de maintien, par le biais de moyens de fixation amovibles, et un plateau destiné à former une surface de contact avec l'une des couches de matière de rembourrage du matelas, laquelle embase et lequel plateau sont raccordés par des moyens de suspension constitués d'au moins une lame déformable.
L'invention concerne encore le matelas constitué d'une carcasse à ressorts telle que décrite ci-dessus, associée à des matières de rembourrage et de garnissage.The invention also relates to a spring member made of thermoplastic material for a mattress carcass as defined above, comprising a base adapted to cooperate with a holding member, by means of removable fastening means, and a plate for forming a contact surface with one of the layers of padding material of the mattress, which base and which plate are connected by means of suspension means consisting of at least one deformable blade.
The invention further relates to the mattress consisting of a spring carcass as described above, associated with padding and lining materials.

L'invention sera encore illustrée, sans aucunement être limitée, par la description suivante de différentes formes de réalisation particulières, données uniquement à titre d'exemples, et représentées sur les dessins annexés dans lesquels :

  • la figure 1 est une vue en coupe longitudinale d'un matelas, montrant schématiquement une première forme de réalisation d'une carcasse à ressorts conforme à l'invention ;
  • la figure 2 est une vue en coupe longitudinale d'un matelas, montrant schématiquement la structure d'une deuxième forme de réalisation d'une carcasse conforme à l'invention ;
  • la figure 3 est encore une vue en coupe longitudinale du matelas représenté sur la figure 2, illustrant ses capacités d'articulation ;
  • la figure 4 est une vue générale en perspective d'un couple d'organes ressorts particuliers, aptes à équiper la carcasse des figures 2 et 3 ;
  • la figure 5 est une vue en coupe verticale selon 5-5 du couple d'organes ressorts de la figure 4.
The invention will be further illustrated, without being limited, by the following description of various particular embodiments, given solely by way of example, and shown in the accompanying drawings in which:
  • the figure 1 is a longitudinal sectional view of a mattress, schematically showing a first embodiment of a spring carcass according to the invention;
  • the figure 2 is a longitudinal sectional view of a mattress, schematically showing the structure of a second embodiment of a carcass according to the invention;
  • the figure 3 is still a longitudinal sectional view of the mattress shown on the figure 2 , illustrating its articulation capabilities;
  • the figure 4 is a general perspective view of a pair of particular spring members, able to equip the carcass of Figures 2 and 3 ;
  • the figure 5 is a vertical sectional view along 5-5 of the pair of spring members of the figure 4 .

La figure 1 est une représentation schématique d'un matelas 1 équipé d'une carcasse 2 conforme à l'invention, laquelle carcasse est classiquement interposée entre deux couches de matériau de rembourrage 3 revêtues d'une épaisseur de garnissage 4.The figure 1 is a schematic representation of a mattress 1 equipped with a carcass 2 according to the invention, which carcass is conventionally interposed between two layers of upholstery material 3 coated with a lining thickness 4.

La carcasse 2 correspondante comprend ici une feuille support 5 sur l'une des faces de laquelle sont agencés une pluralité d'organes ressorts 6. Ces organes ressorts 6 sont chacun fixés sur la feuille 5 de manière démontable au moyen d'un élément de maintien 7 qui est rapporté sur l'autre face de ladite feuille support 5.The corresponding carcass 2 here comprises a support sheet 5 on one of the faces of which are arranged a plurality of spring members 6. These spring members 6 are each fixed on the sheet 5 in a removable manner by means of a holding element 7 which is attached to the other side of said support sheet 5.

La feuille support 5 constitue un moyen de liaison et de maintien, simple et efficace, de l'ensemble des organes ressorts 6 de la carcasse. Cette feuille support 5 a une surface qui correspond pratiquement à la surface totale du matelas ; elle est constituée d'un matériau souple ou semi-rigide, par exemple du genre feuille en matière plastique.
Cette feuille support 5 comporte une pluralité d'orifices 5' au travers desquels les organes ressorts 6 sont aptes à coopérer chacun avec un élément de maintien 7, tel que décrit plus en détail par la suite. A cet effet, la feuille support 5 peut se présenter sous la forme d'une feuille pleine dans laquelle sont aménagés une pluralité d'orifices 5' régulièrement répartis ; elle peut également se présenter sous la forme générale d'une grille ou d'un treillis, dont le calibre des ouvertures est adapté à la coopération entre les organes ressorts 6 et les éléments de maintien associés 7.The support sheet 5 is a means of connection and maintenance, simple and effective, all the spring members 6 of the carcass. This backing sheet 5 has a surface which substantially corresponds to the total surface of the mattress; she is made of a flexible or semi-rigid material, for example of the plastic sheet kind.
This support sheet 5 comprises a plurality of orifices 5 'through which the spring members 6 are each adapted to cooperate with a holding element 7, as described in more detail below. For this purpose, the support sheet 5 may be in the form of a solid sheet in which are arranged a plurality of orifices 5 'regularly distributed; it can also be in the general form of a grid or a mesh, the size of the openings is adapted to the cooperation between the spring members 6 and the associated holding elements 7.

Les organes ressorts correspondants 6 peuvent être réalisés monoblocs ou être constitués de plusieurs parties assemblées les unes aux autres ; ils sont avantageusement réalisés en un matériau thermoplastique, par exemple du genre élastomère.
Ces organes ressorts 6 sont ici chacun constitués - d'une embase 8, apte à reposer contre l'une des faces de la feuille support 5 et apte à coopérer avec l'élément de maintien 7 associé, - d'un plateau 9 assurant le contact contre la couche de rembourrage 3 disposée en regard, et, entre ladite embase 8 et ledit plateau 9 - de moyens de suspension 10, déterminant la fermeté ou la dureté du matelas. Tel qu'illustré sur la figure 1, ces moyens de suspension 10 peuvent consister en des lames déformables ; mais on peut aussi envisager toute autre forme ou structure.The corresponding spring members 6 may be made in one piece or consist of several parts assembled to each other; they are advantageously made of a thermoplastic material, for example of the elastomer type.
These spring members 6 are here each constituted of a base 8, able to rest against one of the faces of the support sheet 5 and adapted to cooperate with the holding member 7 associated, - a plate 9 ensuring the contact against the padding layer 3 disposed opposite, and between said base 8 and said plate 9 - suspension means 10, determining the firmness or the hardness of the mattress. As illustrated on the figure 1 these suspension means 10 may consist of deformable blades; but we can also consider any other form or structure.

Les éléments de maintien 7 des organes ressorts 6, disposés de l'autre côté de la feuille 5, ont une épaisseur la plus réduite possible. Ils sont également réalisés de préférence en un matériau thermoplastique.
Ces éléments de maintien 7 comportent des moyens structurels (non détaillés) aptes à coopérer de manière amovible, ou autrement dit démontable, au travers d'un orifice de réception 5' aménagé dans la feuille support 5, avec des moyens structurels complémentaires aménagés au niveau de l'embase 8 de l'organe ressort 6 associé. Par exemple, ces moyens de fixation amovibles consistent en un système d'encliquetage de type tenon(s)/mortaise(s), dont un exemple de structure sera décrit plus en détail par la suite, en relation avec la figure 5.The holding elements 7 of the spring members 6, arranged on the other side of the sheet 5, have the smallest possible thickness. They are also preferably made of a thermoplastic material.
These holding elements 7 comprise structural means (not detailed) capable of cooperating removably, or in other words removable, through a receiving orifice 5 'arranged in the support sheet 5, with complementary structural means arranged at the level of of the base 8 of the associated spring member 6. For example, these removable fastening means consist of a tenon (s) / mortise (s) type latching system, an example of which structure will be described in more detail later, in connection with the figure 5 .

On remarque encore, sur cette figure 1, que la fixation des organes ressorts 6 est obtenue par la prise en sandwich, ou par pinçage, du pourtour de l'orifice de réception 5' entre l'embase 8 de l'organe ressort 6 et l'élément de maintien 7 associé. L'embase 8 de l'organe ressort 6 et l'élément de maintien 7 associé comportent alors des surfaces planes adaptées.We still notice, on this figure 1 , that the attachment of the spring members 6 is obtained by sandwiching, or by clamping, the periphery of the receiving port 5 'between the base 8 of the spring member 6 and the holding member 7 associated. The base 8 of the spring member 6 and the associated holding member 7 then comprise suitable flat surfaces.

Dans des variantes de réalisation envisageables, un léger jeu peut subsister entre la feuille support 5 et les faces en regard de l'embase 8 et de l'organe de maintien 7, en particulier pour compenser les tolérances d'épaisseur de ladite feuille support 5.In possible embodiments, a slight clearance may remain between the support sheet 5 and the facing faces of the base 8 and the holding member 7, in particular to compensate for the thickness tolerances of said support sheet 5 .

Les figures 2 et 3 représentent un matelas 1 dont la carcasse 2 constitue une variante de celle décrite ci-dessus en relation avec la figure 1.
On retrouve, sur ces figures 2 et 3, une carcasse 2 comprenant une feuille support 5 en matériau souple ou semi-rigide, sur l'une des faces de laquelle sont agencés les organes ressorts 6, dénommés ci-après « premiers organes ressorts ». Ces premiers organes ressorts 6 sont constitués, comme décrit précédemment en relation avec la figure 1, d'une embase 8 raccordée à un plateau 9 par des moyens de suspension 10.The Figures 2 and 3 represent a mattress 1 whose carcass 2 constitutes a variant of that described above in relation to the figure 1 .
We find, on these Figures 2 and 3 , a carcass 2 comprising a support sheet 5 of flexible or semi-rigid material, on one of which are arranged the spring members 6, hereinafter referred to as "first spring members". These first spring members 6 are constituted, as previously described, in connection with the figure 1 , a base 8 connected to a plate 9 by suspension means 10.

Des organes ressorts 6', dénommés ci-après « seconds organes ressorts », sont ici rapportés sur l'autre face de la feuille support 5, chacun en regard de l'un des premiers organes ressorts 6.
Ces seconds organes ressorts 6' ont une structure identique ou similaire à celle des premiers organes ressorts 6 décrits précédemment ; ainsi, ils sont également chacun constitués d'une embase 8', d'un plateau 9' et de moyens de suspension 10' s'étendant entre ladite embase et ledit plateau.Spring members 6 ', hereinafter referred to as "second spring members", are here attached to the other side of the support sheet 5, each facing one of the first spring members 6.
These second spring members 6 'have a structure identical or similar to that of the first spring members 6 described above; thus, they are also each constituted by a base 8 ', a plate 9' and suspension means 10 'extending between said base and said plate.

Comme décrit précédemment en relation avec la figure 1, les premiers organes ressorts 6 sont répartis sur l'une des faces de la feuille support 5, chacun au niveau d'un orifice de réception 5', et ils sont maintenus de manière amovible par l'élément de maintien constitué ici par l'embase 8' d'un second organe ressort 6' disposé en regard, sur l'autre face de la feuille support 5. Les moyens de maintien correspondants sont de préférence des moyens d'encliquetage, assurant une fixation démontable.As previously described in relation to the figure 1 , the first spring members 6 are distributed on one of the faces of the support sheet 5, each at a receiving orifice 5 ', and they are held in a removable manner by the holding element constituted here by the base 8 'of a second spring member 6' arranged facing, on the other side of the support sheet 5. The corresponding holding means are preferably latching means, ensuring a removable attachment.

La feuille support 5 s'étend ici au milieu de la carcasse 2 et au milieu du matelas équipé, interposée entre les couples de premiers et seconds organes ressorts 6 et 6'.The support sheet 5 extends here in the middle of the carcass 2 and in the middle of the fitted mat, interposed between the pairs of first and second spring members 6 and 6 '.

Le matelas 1 muni d'une telle carcasse 2 est alors particulièrement adapté pour équiper les sommiers articulés, du fait de sa souplesse et de ses capacités importantes de déformation, tel que représenté à titre d'illustration sur la figure 3.
Cette capacité de déformation est en particulier conférée par l'emploi d'une feuille support centrale 5 comme moyen de maintien et de fixation des organes ressorts 6, 6' entre eux. La structure de liaison des ressorts est alors positionnée dans un plan d'absence de tension, ce qui permet à la carcasse de se déformer aisément, sans subir de grandes contraintes internes.
Comme on peut le voir sur la figure 3, les extrémités libres des organes ressorts 6, 6' (constituées des plateaux 9, 9') disposent de possibilités de mouvement les unes par rapport aux autres ; elles peuvent se rapprocher et s'écarter pour suivre au mieux les mouvements des couches de rembourrage 3 liés aux déformations du matelas.The mattress 1 provided with such a carcass 2 is then particularly adapted to equip the articulated bed bases, because of its flexibility and its large deformation capacities, as represented by way of illustration on the figure 3 .
This deformation capacity is in particular conferred by the use of a central support sheet 5 as means for holding and fixing the spring members 6, 6 'between them. The linkage structure of the springs is then positioned in a plane of absence of voltage, which allows the carcass to be easily deformed without undergoing large internal stresses.
As can be seen on the figure 3 , the free ends of the springs 6, 6 '(consisting of trays 9, 9') have the possibility of movement relative to each other; they can move closer and apart to better follow the movements of the padding layers 3 related to the deformations of the mattress.

On comprend bien que cette structure permet une utilisation des deux faces du matelas, au choix de l'utilisateur.
En cas de besoin, la structure des organes ressorts 6, 6' disposés de part et d'autre de la feuille support 5 peut être différente pour proposer deux types de dureté. Sur chaque face, on peut aussi envisager d'utiliser des organes ressorts différents, sur certaines zones, de manière à adapter la flexibilité en fonction de la zone du corps supportée.It is understood that this structure allows use of both sides of the mattress, at the option of the user.
If necessary, the structure of the spring members 6, 6 'disposed on either side of the support sheet 5 may be different to provide two types of hardness. On each face, it is also possible to consider using different spring members, in certain areas, so as to adapt the flexibility according to the area of the body supported.

Un couple d'organes ressorts susceptibles d'être rapportés sur une feuille support, en vue de la fabrication d'une carcasse conforme à l'invention, est représenté en détail sur les figures 4 et 5.A pair of spring members that can be attached to a support sheet, for the manufacture of a carcass according to the invention, is shown in detail on the Figures 4 and 5 .

Sur ces figures, on retrouve un premier organe ressort 6 et un second organe ressort 6', tous deux de forme générale tronconique, accolés coaxialement l'un à l'autre sur un axe repéré 11.
Ces deux organes ressorts 6 et 6', réalisés chacun monobloc par moulage de matière thermoplastique, comportent chacun respectivement - une embase 8 et 8', correspondant à la petite base de l'organe ressort, - un plateau 9 et 9' correspondant à la grande base, et - des moyens de suspension 10 et 10' s'étendant entre ladite embase et ledit plateau.
On observe encore que les embases 8 et 8' de ces organes ressorts 6 et 6', ou autrement dit leurs petites bases, sont juxtaposées et solidaires l'une de l'autre, de part et d'autre de la feuille support 5 (figure 5).In these figures, there is a first spring member 6 and a second spring member 6 ', both of generally frustoconical shape, coaxially contiguous to each other on a pin marked 11.
These two spring members 6 and 6 ', each made in one piece by molding of thermoplastic material, each comprise respectively - a base 8 and 8', corresponding to the small base of the spring member, - a plate 9 and 9 'corresponding to the large base, and - suspension means 10 and 10 'extending between said base and said plate.
It is further observed that the bases 8 and 8 'of these spring members 6 and 6', or in other words their small bases, are juxtaposed and secured to one another, on either side of the support sheet 5 ( figure 5 ).

Les plateaux 9 et 9' des deux organes ressorts 6 et 6' sont de forme générale annulaire ; dans des variantes de réalisation ils pourront avoir une forme carrée ou rectangulaire. La face supérieure de ces deux plateaux 9 et 9' est destinée à venir en contact avec l'une des couches de rembourrage du matelas.The plates 9 and 9 'of the two spring members 6 and 6' are of generally annular shape; in alternative embodiments they may have a square or rectangular shape. The upper face of these two plates 9 and 9 'is intended to come into contact with one of the padding layers of the mattress.

Les moyens de suspension 10 et 10' consistent quant à eux en une pluralité de lames ou bras, ici au nombre de huit, qui s'étendent chacun entre l'embase 8 ou 8' et le plateau correspondant 9 ou 9'. Ces lames 10 et 10' sont uniformément réparties sur le périmètre entre l'embase 8, 8' et le plateau 9, 9', de manière à obtenir des caractéristiques de suspension optimales du ressort 6, 6'.The suspension means 10 and 10 'consist in a plurality of blades or arms, here eight in number, which each extend between the base 8 or 8' and the corresponding plate 9 or 9 '. These blades 10 and 10 'are uniformly distributed on the perimeter between the base 8, 8' and the plate 9, 9 ', so as to obtain optimum suspension characteristics of the spring 6, 6'.

Tel qu'illustré sur les figures, ces lames 10, 10' peuvent être raccordées par des liaisons élastiques monoblocs 12, visant à améliorer les caractéristiques de suspension des organes ressorts. Ces structures de liaison 12 ont par exemple une forme générale de oméga.As illustrated in the figures, these blades 10, 10 'can be connected by one-piece resilient links 12, to improve the suspension characteristics. bodies springs. These linking structures 12 have for example a general form of omega.

La structure des lames 10, 10' est adaptée selon la flexibilité recherchée. A proximité des plateaux 9, 9', elles peuvent comporter une courbure relativement prononcée définissant des lignes de pivot 13 facilitant et optimisant l'écrasement des organes ressorts.The structure of the blades 10, 10 'is adapted according to the desired flexibility. In the vicinity of the plates 9, 9 ', they may comprise a relatively pronounced curvature defining pivot lines 13 facilitating and optimizing the crushing of the spring members.

Les embases 8 et 8' juxtaposées des couples d'organes ressorts 6 et 6' sont quant à elles aptes à coopérer par le biais de moyens structurels complémentaires, du genre tenon/mortaise, de sorte à obtenir une fixation amovible desdits organes ressorts 6 et 6' sur la feuille support 5, tel que représenté en détail sur la figure 5.The bases 8 and 8 'juxtaposed pairs of spring members 6 and 6' are for their part able to cooperate by means of complementary structural means, the kind of tenon / mortise, so as to obtain a removable attachment of said spring members 6 and 6 'on the support sheet 5, as shown in detail on the figure 5 .

L'embase 8 du premier ressort 6 a ici une forme générale annulaire, délimitée principalement par une face externe 15, une face interne 16 et un orifice central circulaire 17 formant mortaise. La face interne 16 de cette embase 8 est munie d'une excroissance annulaire 18 au sein de laquelle est aménagé un épaulement annulaire 19. Cet épaulement 19 s'étend de manière concentrique à l'axe 11.
La face externe 15 de l'embase 8 est quant à elle plane, munie uniquement d'une petite nervure annulaire 20, concentrique à l'axe 11, aménagée à distance de l'orifice 17.The base 8 of the first spring 6 here has a generally annular shape, delimited mainly by an outer face 15, an inner face 16 and a circular central hole 17 forming a mortise. The inner face 16 of this base 8 is provided with an annular protrusion 18 within which is arranged an annular shoulder 19. This shoulder 19 extends concentrically to the axis 11.
The outer face 15 of the base 8 is itself flat, provided only with a small annular rib 20, concentric with the axis 11, arranged at a distance from the orifice 17.

L'embase 8' du second ressort 6' est également de forme générale annulaire, délimitée par une face interne 21, une face externe 22, et un orifice central cylindrique 23 coaxial à l'axe 11.
La face externe 22 de cette embase 8' est munie d'un prolongement tubulaire monobloc 24, formant tenon, allongeant l'orifice central cylindrique 23. On notera que ce prolongement tubulaire 24 a un diamètre externe correspondant, au jeu près, à celui du diamètre interne de l'orifice 17 de l'embase 8 du premier ressort 6. Ce tenon 24 comporte encore, au niveau de la face externe de sa bordure d'extrémité libre, des languettes ou ergots saillants monoblocs 25 (ici au nombre de trois) uniformément répartis sur sa périphérie.
La face externe 22 de l'embase 8' comporte encore une petite nervure annulaire 26, aménagée concentriquement à l'axe 11, à proximité de l'orifice 17. Cette nervure annulaire 26 a un diamètre légèrement inférieur à celui de la nervure 20 de l'embase 8.The base 8 'of the second spring 6' is also of generally annular shape delimited by an inner face 21, an outer face 22, and a cylindrical central orifice 23 coaxial with the axis 11.
The outer face 22 of this base 8 'is provided with a tubular one-piece extension 24, forming a tenon, extending the cylindrical central orifice 23. Note that this tubular extension 24 has an outer diameter corresponding, with the game, to that of the internal diameter of the orifice 17 of the base 8 of the first spring 6. This stud 24 further comprises, at the outer face of its free end edge, tongues or integral projecting lugs 25 (here three in number). ) evenly distributed on its periphery.
The outer face 22 of the base 8 'further comprises a small annular rib 26, arranged concentrically with the axis 11, near the orifice 17. This annular rib 26 has a diameter slightly smaller than that of the rib 20 of the base 8.

L'assemblage des deux organes ressorts 6 et 6' sur la feuille support 5, au travers d'un orifice de réception 5', est illustré en détail sur la figure 5.
En l'espèce, le second ressort 6' est agencé de sorte que le tenon cylindrique 24 de son embase 8' traverse l'orifice de réception 5' aménagé dans la feuille support 5. On notera que le diamètre externe du tenon tubulaire 24 est inférieur à celui de l'orifice de réception 5', notamment pour éviter la présence de tension sur la feuille support. La face externe 22 de l'embase 8' de ce second organe ressort 6' vient alors se plaquer contre le pourtour de l'orifice de réception 5'.
Le premier organe ressort 6 est ensuite rapporté sur le second organe ressort 6' convenablement positionné, de sorte que le tenon tubulaire 24 de ce dernier vienne s'emmancher à force au travers de l'orifice 17 de l'embase 8 du premier organe ressort 6, formant mortaise.
Une fois le tenon 24 convenablement emmanché, ses ergots d'extrémités 25 viennent se loger dans l'épaulement annulaire 19 de l'embase 8, ce qui permet une solidarisation efficace des premiers et seconds organes ressorts 6 et 6' l'un avec l'autre, tout en rendant possible leur désolidarisation par un simple écartement à force (la structure des ergots saillants 25 est adaptée en conséquence). Les organes ressorts 6 et 6' sont ainsi maintenus de manière amovible sur la feuille support 5.
On pourra faire en sorte que les efforts nécessaires à la désolidarisation des éléments soient relativement importants pour autoriser cette désolidarisation uniquement par des moyens mécaniques.
Dans cette forme de réalisation, on comprend que l'embase 8' du second organe ressort 6' constitue un élément de maintien du premier organe ressort 6, et inversement que l'embase 8 du premier organe ressort 6 constitue l'élément de maintien du second organe ressort 6'.The assembly of the two spring members 6 and 6 'on the support sheet 5, through a receiving orifice 5', is illustrated in detail on the figure 5 .
In this case, the second spring 6 'is arranged so that the cylindrical pin 24 of its base 8' passes through the receiving orifice 5 'arranged in the support sheet 5. On note that the outer diameter of the tubular post 24 is less than that of the receiving port 5 ', in particular to avoid the presence of tension on the support sheet. The outer face 22 of the base 8 'of the second spring member 6' is then pressed against the periphery of the receiving orifice 5 '.
The first spring member 6 is then attached to the second spring member 6 'suitably positioned, so that the tubular post 24 of the latter comes to force-fit through the orifice 17 of the base 8 of the first spring member 6, forming mortise.
Once the post 24 is properly fitted, its end lugs 25 are housed in the annular shoulder 19 of the base 8, which allows effective attachment of the first and second spring members 6 and 6 ', one with the other, while making it possible to separate them by a simple gaping force (the structure of the protruding lugs 25 is adapted accordingly). The spring members 6 and 6 'are thus held removably on the support sheet 5.
It will be possible to ensure that the forces necessary for separating the elements are relatively important to allow this separation only by mechanical means.
In this embodiment, it is understood that the base 8 'of the second spring member 6' constitutes a holding member of the first spring member 6, and vice versa that the base 8 of the first spring member 6 constitutes the holding member of the second member spring 6 '.

Sur la figure 5, on remarque encore que le pourtour de l'orifice de réception 5' de la feuille support 5 est interposé entre la face externe 15 de l'embase 8 et la face externe 22 de l'embase 8'. La feuille 5 est avantageusement pincée entre les couples d'organes ressorts 6, 6', les nervures annulaires 20 et 26 précitées optimisant le maintien. Comme précisé ci-dessus, on peut aussi envisager des réalisations dans lesquelles les deux organes ressorts 6, 6' sont assemblés de manière amovible en préservant un certain jeu entre les faces externes de leurs embases respectives 8, 8', légèrement supérieur à l'épaisseur de la feuille support 5.On the figure 5 , it is also noted that the periphery of the receiving orifice 5 'of the support sheet 5 is interposed between the outer face 15 of the base 8 and the outer face 22 of the base 8'. The sheet 5 is advantageously clamped between the pairs of spring members 6, 6 ', the annular ribs 20 and 26 above optimizing the maintenance. As specified above, it is also possible to envisage embodiments in which the two spring members 6, 6 'are removably assembled by preserving a certain clearance between the outer faces of their respective bases 8, 8', slightly greater than the thickness of the support sheet 5.

L'assemblage des couples d'organes ressorts 6, 6' entre eux et avec la feuille support 5 peut être réalisé manuellement, mais on utilisera de préférence des moyens mécanisés adaptés.The assembly of the pairs of spring members 6, 6 'with each other and with the support sheet 5 can be done manually, but preferably suitable mechanized means will be used.

On notera encore que l'orifice 23 du tenon 24 du second organe ressort 6' constitue un conduit ou canal assurant une communication entre les espaces situés de part et d'autre de la feuille support 5. Les différents conduits 23 assurent ainsi une aération efficace du volume interne du matelas.It will also be noted that the orifice 23 of the post 24 of the second spring member 6 'constitutes a conduit or channel providing communication between the spaces on either side of the support sheet 5. The different ducts 23 thus provide effective ventilation of the internal volume of the mattress.

Les organes ressorts 6 et 6' illustrés sur les figures 4 et 5 sont réalisés monoblocs, chacun à partir d'un moule différent pour constituer les moyens d'encliquetage complémentaires décrits ci-dessus. Comme précisé auparavant, chaque organe ressort 6, 6' peut aussi être réalisé par assemblage de plusieurs pièces réalisées indépendamment les unes des autres.The spring members 6 and 6 'illustrated on the Figures 4 and 5 are made in one piece, each from a different mold to form the complementary latching means described above. As indicated above, each spring member 6, 6 'can also be achieved by assembling several parts made independently of each other.

Dans des variantes de réalisation les moyens de fixation des organes ressorts entre eux, ou avec des éléments de maintien adaptés, pourront être prévus non amovibles ; dans ce cas, ils seront avantageusement prévus facilement dégradables en vue de faciliter leur démontage pour le recyclage. Par exemple la fixation correspondante peut être réalisée par collage ; on peut aussi envisager une solidarisation au moyen d'ergots, d'organes d'encliquetage ou autres, aptes à perforer et traverser la feuille support souple, la perforation en question formant l'orifice de maintien mentionné ci-dessus.In alternative embodiments the means for fixing the spring members to each other, or with suitable holding elements, may be provided non-removable; in this case, they will advantageously be provided easily degradable to facilitate their disassembly for recycling. For example, the corresponding attachment can be made by gluing; it is also possible to consider a fastening by means of lugs, snap-fasteners or other, able to perforate and pass through the flexible support sheet, the perforation in question forming the holding hole mentioned above.

Les carcasses de type à ressorts conformes à l'invention sont particulièrement intéressantes du fait que leurs différents éléments constitutifs (organes ressorts 6 et 6', feuille support 5, éléments de maintien 7) peuvent tout-à-fait être fabriqués sur un site particulier, puis être transportés dissociés jusqu'au site d'assemblage final du matelas. Cette particularité est possible du fait de la structure simplifiée de la carcasse et de sa facilité de montage. Dans ce cas, on comprend bien que le volume occupé par les carcasses démontées peut être relativement faible, en particulier par rapport au volume occupé par les carcasses de matelas prémontées, connues à ce jour, fournies aux fabricants de matelas. De même, le volume occupé par une carcasse prémontée, conforme à l'invention, reste encore limité, en particulier du fait de sa capacité de déformation au niveau de la feuille support.
Cette structure de carcasse permet également de faciliter les opérations de démontage, en vue de leur recyclage, notamment lors de l'emploi de moyens de fixation amovibles pour solidariser les organes ressorts avec la feuille support.
Les opérations de recyclage en question sont encore optimisées du fait que les différents éléments constitutifs des carcasses sont réalisés en matériau thermoplastique. En outre, les matériaux thermoplastiques correspondants garantissent à l'utilisateur une hygiène optimale de par leur inertie à l'humidité et au confinement, ce qui n'est pas le cas avec les matelas utilisant des ressorts métalliques. De par sa structure et du fait des matériaux utilisés, la carcasse à ressorts conforme à l'invention est relativement légère et d'un coût de revient limité.The spring type carcasses according to the invention are particularly interesting because their various constituent elements (spring members 6 and 6 ', support sheet 5, holding elements 7) can be manufactured on a particular site. , then be transported dissociated to the final assembly site of the mattress. This feature is possible because of the simplified structure of the carcass and its ease of assembly. In this case, it is well understood that the volume occupied by the disassembled carcasses can be relatively low, particularly compared to the volume occupied by the pre-assembled mattress carcasses, known to date, provided to the mattress manufacturers. Similarly, the volume occupied by a pre-assembled carcass, in accordance with the invention, is still limited, in particular because of its capacity for deformation at the level of the support sheet.
This carcass structure also facilitates disassembly operations, for their recycling, especially when using removable fastening means to secure the spring members with the support sheet.
The recycling operations in question are further optimized because the various constituent elements of the carcasses are made of thermoplastic material. In addition, the corresponding thermoplastic materials guarantee the user optimum hygiene by their inertia to moisture and confinement, which is not the case with mattresses using metal springs. Due to its structure and because of the materials used, the spring carcass according to the invention is relatively light and has a limited cost.
