Abstract

The invention relates to a spring mattress of which the body is formed by spaced apart rows of springs connected by elastically deformable members. The latter enable the body to bend along transverse lines of break located between the rows of springs, with the result that the mattress is so flexible as to be adapted for use on an articulated bedstead or slatted framework.

Description

L'invention se rapporte à un matelas à ressorts comportant, dans une enveloppe souple, une carcasse élastique composée d'un assemblage de ressorts répartis en ensembles transversaux formant des rangées successives, les ressorts de chaque ensemble s'inscrivant dans un prisme à base sensiblement rectangulaire et ces prismes, juxtaposés suivant la direction longitudinale du matelas, définissant par leurs faces latérales opposées libres les deux surfaces principales du matelas, tandis que deux ensembles adjacents de ressorts sont reliés entre eux exclusivement au niveau des arêtes contiguës des prismes qui les délimitent, situées dans lesdites surfaces principales.The invention relates to a spring mattress comprising, in a flexible envelope, an elastic carcass composed of an assembly of springs distributed in transverse assemblies forming successive rows, the springs of each assembly being inscribed in a prism with a substantially base rectangular and these prisms, juxtaposed in the longitudinal direction of the mattress, defining by their free opposite lateral faces the two main surfaces of the mattress, while two adjacent sets of springs are interconnected exclusively at the contiguous edges of the prisms which delimit them, located in said main surfaces.

Les matelas à ressorts de ce genre sont bien connus et largement utilisés. Ils présentent sur les matelas de mousse ou de latex les avantages d'être plus hygiéniques grâce au grand volume d'air qu'ils contiennent, de ne pas présenter de risques d'allergie pour les utilisateurs et d'offrir une excellente stabilité de forme dans le temps. Toutefois, ils sont relativement rigides et se prêtent mal à l'utilisation sur sommiers articulés, lesquels doivent recevoir des matelas de mousse ou de latex, ceux-ci présentant la flexibilité nécessaire pour s'adapter à la configuration anguleuse que peuvent prendre de tels sommiers. Le terme "sommiers" doit ici s'entendre de supports de toutes formes pour matelas, y compris les cadres à lattes.Spring mattresses of this kind are well known and widely used. They have the advantages of being more hygienic on foam or latex mattresses thanks to the large volume of air they contain, of not presenting any risk of allergy for users and of offering excellent shape stability. in time. However, they are relatively rigid and do not lend themselves to use on articulated mattresses, which must receive foam or latex mattresses, these having the flexibility necessary to adapt to the angular configuration that such mattresses can take. . The term "box springs" should be understood here to mean supports of all shapes for mattresses, including slatted frames.

L'invention a pour but de remédier à cet inconvénient afin de permettre l'utilisation de matelas à ressorts sur des sommiers articulés.The invention aims to remedy this drawback in order to allow the use of spring mattresses on articulated bed bases.

Dans ce but, selon l'invention, au moins deux ensembles adjacents parmi les ensembles de ressorts composant la carcasse du matelas sont disposés avec un certain espacement mutuel_et sont reliés, au travers de l'intervalle ainsi créé, par des éléments élastiquement déformables, capables de reprendre des efforts aussi bien d'extension que de compression, qui permettent aux arêtes en regard des prismes délimitant ces ensembles de se rapprocher ou de s'écarter mutuellement, et autorisent ainsi une cassure des surfaces principales du matelas par flexion au droit dudit intervalle.For this purpose, according to the invention, at least two adjacent sets among the sets of springs composing the carcass of the mattress are arranged with a certain mutual space and are connected, through the gap thus created, by elastically deformable elements, capable to resume efforts of both extension and compression, which allow the edges facing the prisms delimiting these assemblies to approach or move away from each other, and thus allow a breakage of the main surfaces of the mattress by bending at the right of said interval.

Ainsi, ces deux ensembles de ressorts sont non pas en contact mutuel et directement reliés l'un à l'autre comme il est habituel de faire, mais reliés par l'intermédiaire d'éléments élastiquement déformables qui créent entre ces deux ensembles une zone flexible jouant le rôle d'une charnière et permettant ainsi à la carcasse, donc au matelas, de plier suivant une ligne de cassure transversale correspondante. Cette zone de charnière étant disposée en regard d'une articulation du sommier articulé appelé à recevoir le matelas, ce dernier peut fléchir et prendre une configuration anguleuse semblable à celle donnée au sommier.Thus, these two sets of springs are not in mutual contact and directly connected to each other as is usual, but connected by means of elastically deformable elements which create between these two sets a flexible zone playing the role of a hinge and thus allowing the carcass, and therefore the mattress, to fold along a corresponding transverse break line. This hinge area being arranged opposite an articulation of the articulated bed base called to receive the mattress, the latter can bend and take an angular configuration similar to that given to the bed base.

Considérant que la ou les articulations d'un sommier articulé peuvent se trouver en diverses positions sur sa longueur, il est préférable que tous les ensembles de ressorts soient espacés mutuellement et reliés dans les intervalles ainsi créés par des éléments élastiquement déformables, ainsi qu'il a été exposé plus haut pour deux ensembles adjacents au moins. La carcasse est ainsi dotée d'un grand nombre de lignes de cassure transversales situées entre les ensembles successifs de ressorts.Considering that the articulation (s) of an articulated mattress can be in various positions along its length, it is preferable that all the sets of springs are spaced apart and connected in the intervals thus created by elastically deformable elements, as well as has been described above for at least two adjacent sets. The carcass is thus provided with a large number of transverse break lines located between the successive sets of springs.

Dans une forme d'exécution avantageuse, les éléments de liaison précités comprennent des premiers éléments élastiquement déformables disposés entre les arêtes homologues des ensembles de ressorts respectivement situées dans une même surface principale du matelas et, pour assurer la stabilité horizontale du matelas, des seconds éléments élastiquement déformables disposés en biais dans l'épaisseur de la carcasse entre les arêtes non contiguës desdits ensembles adjacents situées respectivement dans l'une et dans l'autre desdites surfaces principales.In an advantageous embodiment, the aforementioned connecting elements comprise first elastically deformable elements arranged between the homologous edges of the sets of springs respectively located in the same main surface of the mattress and, to ensure the horizontal stability of the mattress, second elements elastically deformable disposed at an angle in the thickness of the carcass between the non-contiguous edges of said adjacent assemblies situated respectively in one and in the other of said main surfaces.

Seules les liaisons dans une surface principale déterminée pourraient être assurées par des premiers éléments élastiquement déformables, les liaisons dans l'autre surface principale se faisant grâce à des éléments d'articulation non déformables. Mais il est préférable, afin d'augmenter les possibilités de flexion angulaire du matelas, que les arêtes homologues contiguës des ensembles adjacents de ressorts situées aussi bien dans l'une que dans l'autre des surfaces principales soient reliées par des premiers éléments élastiquement déformables. D'autre part, pour améliorer la stabilité du matelas vis-à-vis d'efforts de cisaillement suivant sa direction longitudinale, il convient de prévoir que les arêtes d'attache des seconds éléments situées dans une même surface principale appartiennent alternativement, le long de l'intervalle correspondant, à l'un et à l'autre des deux ensembles reliés par ces éléments, lesquels se trouvent ainsi disposés obliquement tantôt dans un sens, tantôt dans l'autre.Only the connections in a given main surface could be provided by first elastically deformable elements, the connections in the other main surface being made by non-deformable articulation elements. But it is preferable, in order to increase the possibilities of angular bending of the mattress, than the contiguous homologous edges of the adjacent sets of springs located in both of the main surfaces are connected by first elastically deformable elements. On the other hand, to improve the stability of the mattress with respect to shearing forces along its longitudinal direction, it should be provided that the attachment edges of the second elements located in the same main surface belong alternately, along of the corresponding interval, one and the other of the two sets connected by these elements, which are thus arranged obliquely sometimes in one direction, sometimes in the other.

Les éléments de liaison peuvent être constitués par des tiges élastiques façonnées en forme de zigzag plan, savoir de préférence en forme de S applati pour les premiers éléments et, de préférence également, en forme de E pour les seconds éléments. Certaines au moins des tiges élastiques constituant les éléments de liaison peuvent en outre être enroulées sur elles-mêmes en une ou plusieurs boucles dans la région de l'un au moins des angles qu'elles comportent.The connecting elements may be constituted by elastic rods shaped in the form of a flat zigzag, namely preferably in the form of an S flattened for the first elements and, preferably also, in the form of E for the second elements. At least some of the elastic rods constituting the connecting elements can also be wound on themselves in one or more loops in the region of at least one of the angles which they comprise.

Dans une forme d'exécution particulièrement simple, les éléments de liaison sont groupés en organes de liaison formés d'une tige élastique d'un seul tenant qui est façonnée pour faire apparaître deux premiers éléments dans des plans parallèles et un second élément interposé en biais entre ceux-ci, les plans de ces trois éléments ainsi réunis étant agencés de façon que leur section par un plan perpendiculaire présente la forme d'un Z.In a particularly simple embodiment, the connecting elements are grouped into connecting members formed of an elastic rod in one piece which is shaped to reveal two first elements in parallel planes and a second element interposed at an angle between them, the planes of these three elements thus united being arranged so that their section by a perpendicular plane has the shape of a Z.

D'autres caractéristiques et avantages de l'invention ressortiront plus clairement de la description qui va suivre, en regard des dessins annexés, d'un exemple de réalisation non limitatif.Other characteristics and advantages of the invention will emerge more clearly from the description which follows, with reference to the appended drawings, of a nonlimiting exemplary embodiment.

  • Les figures 1 et 2 représentent, respectivement en élévation latérale et en plan, une portion de la carcasse d'un matelas à ressorts selon l'invention.Figures 1 and 2 show, respectively in side elevation and in plan, a portion of the carcass of a spring mattress according to the invention.
  • La figure 3 représente, en perspective et à plus grande échelle, l'un des organes de liaison que comporte la carcasse des figures 1 et 2.FIG. 3 represents, in perspective and on a larger scale, one of the connecting members that comprises the carcass of FIGS. 1 and 2.
  • Les figures 4 à 6 représentent schématiquement, en élévation latérale, une vue partielle d'une carcasse de matelas conforme aux figures 1 et 2 en situation fléchie sur un cadre à lattes articulé, chacune de ces figures montrant une répartition particulière des lattes par rapport aux ressorts du matelas.Figures 4 to 6 schematically show, in side elevation, a partial view of a mattress carcass according to Figures 1 and 2 in a flexed situation on an articulated slat frame, each of these figures showing a particular distribution of the slats relative to the mattress springs.

Conformément aux figures 1 et 2, un matelas à ressorts selon l'invention comporte une armature ou carcasse élastique formée d'un assemblage de ressorts 1, que vient recouvrir une enveloppe textile souple (non représentée). Les ressorts 1 sont des ressorts biconiques classiques, constitués par un enroulement de fil métallique élastique qui se termine par deux spires planes et circulaires formant les têtes ou pavillons du ressort. Les ressorts 1 sont répartis en ensembles linéaires 2 formant des rangées transversales qui se succèdent suivant la direction longitudinale 3 du matelas, leurs pavillons étant respectivement contenus dans deux plans parallèles 4, 5 qui définissent les surfaces principales du matelas. Les ensembles 2 de ressorts 1 s'inscrivent dans des volumes prismatiques transversaux, de section rectangulaire, dont les arêtes sont matérialisées par de longs fils 6, 7 boudinés hélicoidalement, dans les spires desquels sont prises des parties latérales des pavillons des ressorts 1. D'autres fils hélicoidaux 8 s'étendent suivant les arêtes longitudinales du matelas et sont engagés sur des parties des pavillons des ressorts extrêmes des ensembles 2.In accordance with Figures 1 and 2, a spring mattress according to the invention comprises an elastic frame or carcass formed of an assembly of springs 1, which is covered by a flexible textile envelope (not shown). The springs 1 are conventional biconical springs, constituted by a winding of elastic metallic wire which ends in two flat and circular turns forming the heads or horns of the spring. The springs 1 are distributed in linear assemblies 2 forming transverse rows which follow one another in the longitudinal direction 3 of the mattress, their pavilions being respectively contained in two parallel planes 4, 5 which define the main surfaces of the mattress. The sets 2 of springs 1 are part of transverse prismatic volumes, of rectangular section, the edges of which are materialized by long wires 6, 7 helically spherical, in the turns of which are taken lateral parts of the pavilions of the springs 1. D other helical wires 8 extend along the longitudinal edges of the mattress and are engaged on parts of the pavilions of the extreme springs of the assemblies 2.

Les ensembles successifs 2 de ressorts 1 ne sont pas accolés, mais espacés par des intervalles 11 égaux de largeur, dans lesquels prennent place des organes élastiques la de liaison qui assurent l'assemblage desdits ensembles 2. Chacun de ces organes 10 est constitué par un fil élastique, de préférence métallique (du type "corde à piano"), contourné pour faire apparaître (figure 3) trois éléments élastiques plans, savoir deux premiers éléments lOa, lOb en forme de S applati réunis par un second élément lOc en forme de Σ. Les plans A, B des premiers éléments lOa, lOb sont parallèles et distants d'une quantité égale à la hauteur des ressorts 1, c'est-à-dire à l'épaisseur e de la carcasse du matelas (figure 1). Le plan C dans lequel est contenu l'élément intermédiaire 10c n'est pas perpendiculaire aux plans A, B des éléments extrêmes lOa, lOb, mais s'étend obliquement par rapport à ceux-ci, de sorte qu'une section par un plan perpendiculaire aux trois plans précités a la forme d'un Z. Les branches extrêmes de l'élément 10c en forme de ¿ coïncident avec les intersections du plan C avec les plans A et B et sont confondues avec les branches extrêmes respectives des éléments lOa, lOb par lesquelles ces derniers se raccordent à l'élément 10c. Les éléments lOa et lOb en forme de S sont identiques. Ils ont une longueur égale à la valeur a des intervalles 11 et comprennent trois branches rectilignes parallèles réunies par des portions incurvées semi-circulaires. Dans la région comprise entre ses deux branches obliques, l'élément 10c comporte une boucle circulaire 14 augmentant la flexibilité de l'élément à cet endroit. Chaque élément élastique lOa, lOb, 10c peut travailler dans son plan aussi bien en compression qu'en extension. Des déformations angulaires élastiques peuvent se produire en outre entre chacun des éléments lOa, lOb et l'élément intermédiaire lOc.The successive sets 2 of springs 1 are not placed side by side, but spaced by intervals 11 equal in width, in which resilient connecting members take place which ensure the assembly of said sets 2. Each of these members 10 is constituted by a elastic wire, preferably metallic (of the "piano string" type), bypassed to reveal (figure 3) three flat elastic elements, namely the first two elements lOa, lOb in the form of flattened S joined by a second element lOc in the form of Σ. The planes A, B of the first elements 10a, 10b are parallel and distant by an amount equal to the height of the springs 1, that is to say to the thickness e of the mattress frame (figure 1). The plane C in which the intermediate element 10c is contained is not perpendicular to the planes A, B of the extreme elements lOa, lOb, but extends obliquely with respect to them, so that a section through a plane perpendicular to the three aforementioned planes has the shape of a Z. The extreme branches of the element 10c in the form of ¿coincide with the intersections of the plane C with the planes A and B and are merged with the respective extreme branches of the elements lOa, lOb by which the latter are connected to the element 10c. The S-shaped elements lOa and lOb are identical. They have a length equal to the value at intervals 11 and include three parallel rectilinear branches joined by curved semicircular portions. In the region between its two oblique branches, the element 10c has a circular loop 14 increasing the flexibility of the element at this location. Each elastic element 10a, 10b, 10c can work in its plane both in compression and in extension. Elastic angular deformations can also occur between each of the elements 10a, 10b and the intermediate element 10c.

Les organes de liaison 10 sont disposés dans les intervalles 11 séparant les ensembles 2 de ressorts 1 adjacents. Les éléments lOa et lOb de ces organes sont pris par leurs branches extrêmes, terminées par des queues de blocage 13, dans les fils hélicoidaux d'attache 6, 7 (figure 1), de sorte que ces éléments sont contenus respectivement dans les plans 4 et 5. Plusieurs organes de liaison sont utilisés pour réunir deux ensembles 2 adjacents, qui sont répartis sur la longueur de l'intervalle 11 correspondant. Ces organes 10 sont orientés alternativement dans un sens et dans l'autre, de sorte que-les plans C de leurs éléments intermédiaires 10c présentent une obliquité de sens alterné, la section de ces plans par un plan perpendiculaire ayant la forme d'un X, comme on peut le voir sur les figures 1 et 4. Ces éléments, reliant obliquement les têtes des ressorts 1 à travers l'épaisseur e de la carcasse, assurent, par un effet de triangulation croisée, la stabilité de celle-ci malgré la déformabilité des éléments de liaison 10a, 10b situés dans les plans principaux 4, 5.The connecting members 10 are arranged in the intervals 11 separating the sets 2 of springs 1 adjacent. The elements 10a and 10b of these members are taken up by their end branches, terminated by locking tails 13, in the helical attachment wires 6, 7 (FIG. 1), so that these elements are contained respectively in the planes 4 and 5. Several connecting members are used to join two adjacent sets 2, which are distributed over the length of the corresponding interval 11. These members 10 are oriented alternately in one direction and in the other, so that the planes C of their intermediate elements 10c have an obliquity of alternating direction, the section of these planes by a perpendicular plane having the shape of an X , as can be seen in FIGS. 1 and 4. These elements, obliquely connecting the heads of the springs 1 through the thickness e of the carcass, ensure, by an effect of crossed triangulation, the stability thereof despite the deformability of the connecting elements 10a, 10b located in the main planes 4, 5.

La carcasse à ressorts décrite est susceptible de quitter sa conformation plane naturelle et de se plier, suivant une ligne de cassure transversale (figure 4), au droit d'un intervalle 11 entre deux ensembles 2 adjacents de ressorts , pour Épouser les différentes conformations que peut prendre un sommier articulé 15 (ici un cadre à lattes). Les organes de liaison 10 introduits entre ces ensembles de ressorts sont en effet élastiquement déformables; le long de la ligne de cassure, les éléments 10a situés dans le plan 4 se compriment et les éléments opposés 10b situés dans le plan 5 se dilatent. Les lattes 12 sont réparties de façon qu'il y ait une latte sous chacune des rangées de ressorts 1 et d'organes de liaison 10. En variante, les lattes 12 peuvent être disposées uniquement sous les rangées d'organes 10 (figure 5), ou uniquement sous les rangées de ressorts 1 (figure 6).The spring carcass described is capable of leaving its natural plane conformation and of bending, along a transverse break line (FIG. 4), in line with an interval 11 between two adjacent sets 2 of springs, to match the different conformations that can take an articulated base 15 (here a slatted frame). The connecting members 10 introduced between these sets of springs are in fact elastically deformable; along the break line, the elements 10a located in the plane 4 compress and the opposite elements 10b located in the plane 5 expand. The slats 12 are distributed so that there is a slat under each of the rows of springs 1 and of connecting members 10. As a variant, the slats 12 can be arranged only under the rows of members 10 (FIG. 5) , or only under the rows of springs 1 (Figure 6).

Dans le matelas représenté à titre d'exemple, les organes de liaison 10 ont à peu près la même étendue, suivant la direction transversale, que les ressorts 1, et sont répartis dans cette direction au même pas que ces derniers, chaque organe 10 coïncidant avec une paire de ressorts 1 en regard qu'il relie entre eux. Cela n'est toutefois pas indispensable, et l'on peut envisager des organes de liaison dimensionnés et répartis différemment vis-à-vis des ressorts 1 des ensembles successifs 2.In the mattress shown by way of example, the connecting members 10 have approximately the same extent, in the transverse direction, as the springs 1, and are distributed in this direction at the same pitch as the latter, each member 10 coinciding with a pair of facing springs 1 which it connects together. However, this is not essential, and it is possible to envisage connecting members dimensioned and distributed differently with respect to the springs 1 of the successive sets 2.

Les éléments 10c de la carcasse d'un matelas selon l'invention, interposés entre les deux surfaces principales, interviennent dans le degré de souplesse du matelas, conjointement avec les ressorts 1. Il est donc possible, en jouant sur les caractéristiques de ces éléments qui constituent ainsi des ressorts auxiliaires, de modifier les propriétés de confort du matelas sans toucher aux ressorts 1.The elements 10c of the carcass of a mattress according to the invention, interposed between the two main surfaces, are involved in the degree of flexibility of the mattress, together with the springs 1. It is therefore possible, by playing on the characteristics of these elements which thus constitute auxiliary springs, to modify the comfort properties of the mattress without touching the springs 1.

On a représenté en tirets sur la figure 3 une variante de réalisation des organes de liaison 10, selon laquelle, pour faciliter la fabrication du matelas, les branches extrêmes de leurs éléments 10a, b sont non pas rectilignes, mais incurvées avec une convexité respectivement tournée vers les ressorts 1 auxquels elles doivent être attachées.There is shown in broken lines in Figure 3 an alternative embodiment of the connecting members 10, according to which, to facilitate the manufacture of the mattress, the extreme branches of their elements 10a, b are not straight, but curved with a convexity respectively turned towards the springs 1 to which they must be attached.
