Description

L'invention concerne le domaine de la suspension élastique des sommiers de literie, qui sont destinés à supporter un couchage, tel un matelas par exemple.The invention relates to the field of the elastic suspension of bed bases, which are intended to support a bed, such as a mattress for example.

Elle concerne plus précisément un dispositif de suspension monobloc pour un sommier, comportant :

  • une partie supérieure destinée à supporter un couchage ;
  • une partie inférieure destinée à être fixée au sommier ;
  • une partie intermédiaire constituée par des éléments de suspension reliant entre-elles les parties inférieure et supérieure, les éléments de suspension présentant des premier et deuxième plans de symétrie orthogonaux, les éléments de suspension comportant une paire de parois de suspension élastiques externes symétriques par rapport au premier plan de symétrie, chacune des parois de suspension externes présentant au moins une ligne courbe moyenne s'étendant dans le deuxième plan de symétrie, chacune des parois de suspension externes étant apte à se plier selon au moins une ligne de pliage sensiblement orthogonale au deuxième plan de symétrie.
It relates more specifically to a monobloc suspension device for a bed base, comprising:
  • an upper portion for supporting a bed;
  • a lower part intended to be fixed to the bed base;
  • an intermediate part constituted by suspension elements interconnecting the lower and upper parts, the suspension elements having orthogonal first and second orthogonal planes of symmetry, the suspension elements comprising a pair of external elastic suspension walls symmetrical with respect to the first plane of symmetry, each of the outer suspension walls having at least one mean curved line extending in the second plane of symmetry, each of the outer suspension walls being adapted to bend along at least one fold line substantially orthogonal to the second plane of symmetry.

Traditionnellement, un tel dispositif peut être fixé directement à un long pan d'un cadre du sommier, ou bien être monté sur une latte de fixation, cette dernière étant alors fixée au long pan du sommier.Traditionally, such a device can be attached directly to a long side of a frame of the bed base, or be mounted on a lath fixing, the latter then being fixed to the long pan of the bed.

Parmi les dispositifs directement fixés au long pan du sommier, on connaît les embouts décrits dans le document FR 2 885 021 et les dispositifs décrits dans le document DE 196 46 633 .Among the devices directly attached to the long pan of the bed base, we know the tips described in the document FR 2,885,021 and the devices described in the document DE 196 46 633 .

Ces embouts offrent une bonne stabilité vis-à-vis du roulis et du tangage, ainsi qu'une raideur de suspension verticale correcte.These tips offer good stability with regard to roll and pitch, as well as a correct vertical suspension stiffness.

Un but de l'invention est de fournir un dispositif de suspension présentant une qualité de suspension améliorée.An object of the invention is to provide a suspension device having improved suspension quality.

L'invention atteint son but par le fait que les éléments de suspension du dispositif de suspension comportent en outre au moins une paire de parois de suspension élastiques internes symétriques par rapport au premier plan de symétrie, chacune des parois de suspension internes présentant au moins une ligne courbe moyenne s'étendant dans le deuxième plan de symétrie, chacune des parois de suspension internes étant apte à se plier selon des première, deuxième et troisième lignes de pliage distinctes sensiblement orthogonales au deuxième plan de symétrie, que chacune des parois de suspension internes, considérée verticalement depuis la partie supérieure vers la partie inférieure, comporte successivement des première, deuxième et troisième portions coudées définissant respectivement les première, deuxième et troisième lignes de pliage, que deux portions coudées adjacentes s'ouvrent vers des directions opposées, que chacune des parois de suspension internes comporte une première extrémité fixée à la partie supérieure du dispositif et une seconde extrémité fixée à la partie inférieure du dispositif et que, considéré dans le deuxième plan de symétrie, le dispositif de suspension étant au repos, la distance entre la première extrémité de la paroi de suspension interne et la deuxième ligne de pliage est sensiblement égale au double de la distance entre la deuxième ligne de pliage et la seconde extrémité de la paroi de suspension interne.The invention achieves its object by the fact that the suspension elements of the suspension device further comprise at least one pair of internal elastic suspension walls symmetrical with respect to the first plane of symmetry, each of the internal suspension walls. having at least one mean curved line extending in the second plane of symmetry, each of the inner suspension walls being adapted to bend along first, second and third distinct fold lines substantially orthogonal to the second plane of symmetry, that each of the internal suspension walls, considered vertically from the upper part to the lower part, comprises successively first, second and third bent portions respectively defining the first, second and third fold lines, two adjacent bent portions open towards opposite directions , that each of the inner suspension walls has a first end fixed to the upper part of the device and a second end fixed to the lower part of the device and that, considered in the second plane of symmetry, the suspension device being at rest, the distance between the first end of the inner suspension wall and the second fold line is substantially equal to twice the distance between the second fold line and the second end of the inner suspension wall.

Grâce à ces trois lignes de pliages, les parois de suspension internes sont fractionnées en au moins quatre parties qui tendent à s'empiler les unes sur les autres lorsque le dispositif de suspension est soumis à une charge verticale.With these three fold lines, the inner suspension walls are split into at least four parts which tend to stack on top of each other when the suspension device is subjected to a vertical load.

Par « vertical », on entend ici une direction sensiblement parallèle à la droite définie par l'intersection des premier et deuxième plans de symétrie.By "vertical" is meant here a direction substantially parallel to the line defined by the intersection of the first and second planes of symmetry.

Ainsi, lorsque le dispositif de suspension selon l'invention plie sous l'action d'une charge, les bras de la troisième portion coudée tendent à s'empiler l'un sur l'autre avant que les bras de la première portion coudée ne s'empilent à leur tour l'un sur l'autre, grâce à quoi la paroi de suspension interne présente une raideur progressive lors du pliage du dispositif de suspension. Dès lors, la raideur des portions de suspension internes augmente à mesure que lesdites parties s'empilent les unes sur les autres.Thus, when the suspension device according to the invention bends under the action of a load, the arms of the third bent portion tend to stack one on the other before the arms of the first bent portion do not stack in turn one on the other, whereby the inner suspension wall has a progressive stiffness when folding the suspension device. Therefore, the stiffness of the inner suspension portions increases as said parts stack on top of each other.

Au contraire, les parois de suspension externes, comportant moins de lignes de pliage, présentent une raideur qui évolue moins que celle des portions de suspension internes.On the contrary, the outer suspension walls, with fewer fold lines, have a stiffness that changes less than that of the internal suspension portions.

Comme les parois de suspension internes et externes sont reliées toutes deux aux parties inférieure et supérieure, l'interaction lors du pliage entre les portions de suspension internes et externes entraine un couplage mécanique des raideurs desdites portions, en conséquence de quoi la raideur globale des éléments de suspension du dispositif présente une progressivité verticale fournissant à l'utilisateur un confort amélioré.As the inner and outer suspension walls are both connected to the lower and upper parts, the interaction during folding between the inner and outer suspension portions results in a mechanical coupling of the stiffness of said portions, as a result of which the overall stiffness of the elements suspension of the device has a vertical progressivity providing the user with improved comfort.

Avantageusement, les parois de suspension internes sont disposées dans un volume délimité par les parois de suspension externes.Advantageously, the internal suspension walls are arranged in a volume defined by the external suspension walls.

De préférence, les parois de suspension externes sont aptes à prendre appui sur les parois de suspension internes lorsqu'une charge est appliquée au dispositif selon l'invention.Preferably, the external suspension walls are able to bear on the internal suspension walls when a load is applied to the device according to the invention.

Avantageusement, chacune des parois de suspension externes comporte au moins une partie coudée définissant la ligne de pliage de ladite paroi.Advantageously, each of the external suspension walls comprises at least one bent part defining the fold line of said wall.

Ainsi, chacune des parois de suspension externes est apte à se plier autour de la portion coudée.Thus, each of the outer suspension walls is able to bend around the bent portion.

De manière préférentielle, chacune des parois de suspension externes comporte une unique portion coudée.Preferably, each of the external suspension walls comprises a single bent portion.

Sans sortir du cadre de la présente invention, les parois de suspension externes peuvent également présenter une forme sensiblement incurvée tel un « C », la ligne de pliage passant alors sensiblement par le milieu de la paroi.Without departing from the scope of the present invention, the outer suspension walls may also have a substantially curved shape such as a "C", the fold line then passing substantially through the middle of the wall.

De manière préférentielle, la ligne de pliage de chacune des parois de suspension externes est disposée sensiblement à mi-distance des parties inférieure et supérieure du dispositif de suspension selon l'invention.Preferably, the fold line of each of the external suspension walls is disposed substantially midway between the lower and upper parts of the suspension device according to the invention.

De manière préférentielle, au moins l'une des portions coudées s'ouvre vers une intersection des premier et deuxième plans de symétrie, tandis qu'au moins l'une des autres portions coudées s'ouvre vers la paroi de suspension externe la plus proche.Preferably, at least one of the bent portions opens to an intersection of the first and second planes of symmetry, while at least one of the other bent portions opens to the nearest outer suspension wall .

Avantageusement, dans chacune des parois de suspension internes, deux portions coudées adjacentes s'ouvrent vers des directions opposées, grâce à quoi les portions de suspension internes peuvent se replier ou s'empiler sur elles-mêmes.Advantageously, in each of the inner suspension walls, two adjacent bent portions open in opposite directions, whereby the inner suspension portions can fold or stack on themselves.

Ainsi, vu dans le deuxième plan de symétrie, les parois de suspension internes présentent de préférence sensiblement la forme d'un « Σ » constitué de trois portions coudées juxtaposées.Thus, seen in the second plane of symmetry, the inner suspension walls preferably have substantially the shape of a "Σ" consisting of three bent portions juxtaposed.

Autrement dit, chacune des portions coudées comporte deux bras qui sont avantageusement aptes à s'empiler l'un sur l'autre lorsque l'on soumet le dispositif de suspension à une charge verticale.In other words, each of the bent portions comprises two arms which are advantageously able to stack one on the other when the suspension device is subjected to a vertical load.

Avantageusement, la première portion coudée est la plus proche de la première extrémité de ladite paroi de suspension interne, et les première et troisième portions coudées s'ouvrent vers une intersection des premier et deuxième plans de symétrie, tandis que la deuxième portion coudée s'ouvre vers la paroi de suspension externe la plus proche.Advantageously, the first bent portion is closest to the first end of said inner suspension wall, and the first and third bent portions open to an intersection of the first and second planes of symmetry, while the second bent portion s' open to the nearest outer suspension wall.

Avantageusement, vue selon une direction transversale du dispositif, la largeur des parois de suspension internes est sensiblement égale à la largeur des parois de suspension externes.Advantageously, seen in a transverse direction of the device, the width of the internal suspension walls is substantially equal to the width of the external suspension walls.

Par direction transversale, on entend ici une direction orthogonale au deuxième plan de symétrie.By transverse direction, here means a direction orthogonal to the second plane of symmetry.

Grâce à cette conformation, le dispositif selon l'invention présente un encombrement transversal réduit.Thanks to this conformation, the device according to the invention has a reduced transverse bulk.

Selon un deuxième mode de réalisation avantageux de l'invention, la première portion coudée est la plus proche de la première extrémité de la portion de suspension interne, et la deuxième portion coudée s'ouvre vers une intersection des premier et deuxième plans de symétrie, tandis que les première et troisième portions coudées s'ouvrent vers la paroi de suspension externe la plus proche.According to a second advantageous embodiment of the invention, the first bent portion is closest to the first end of the inner suspension portion, and the second bent portion opens to an intersection of the first and second planes of symmetry, while the first and third bent portions open to the nearest outer suspension wall.

De manière particulièrement avantageuse, les secondes extrémités des parois de suspension internes sont fixées entre elles par une membrane souple s'étendant selon une direction longitudinale dudit dispositif perpendiculaire au premier plan de symétrie.Particularly advantageously, the second ends of the inner suspension walls are fixed together by a flexible membrane extending in a longitudinal direction of said device perpendicular to the first plane of symmetry.

On réalise ainsi un couplage mécanique entre les parois de suspension internes, dont un intérêt est d'améliorer la solidité des éléments de suspension.This provides a mechanical coupling between the inner suspension walls, an interest of which is to improve the strength of the suspension elements.

Grâce à cette conformation, on obtient un dispositif de suspension à la fois léger et solide.With this conformation, we obtain a suspension device both light and strong.

Avantageusement, les éléments de suspension sont inscrits dans un volume sphérique.Advantageously, the suspension elements are inscribed in a spherical volume.

Cette forme avantageuse permet un débattement de la suspension plus important autour de l'axe vertical, tout en améliorant la solidité du dispositif selon l'invention.This advantageous form allows a greater travel of the suspension around the vertical axis, while improving the strength of the device according to the invention.

Avantageusement, les éléments de suspension présentent une structure en nid d'abeilles.Advantageously, the suspension elements have a honeycomb structure.

Grâce à la structure en nid d'abeille, le dispositif de suspension selon l'invention est léger tout en étant particulièrement solide. Aussi, grâce à cette géométrie particulière, les efforts subis par le dispositif de suspension sont répartis de manière homogène dans les différentes parois de suspension du dispositif.Thanks to the honeycomb structure, the suspension device according to the invention is lightweight while being particularly strong. Also, thanks to this particular geometry, the forces experienced by the suspension device are distributed homogeneously in the various suspension walls of the device.

Avantageusement, la partie inférieure comporte au moins un manchon pour la fixation à un tenon solidaire d'un cadre du sommier.Advantageously, the lower part comprises at least one sleeve for attachment to a tenon integral with a frame of the bed.

Avantageusement, la partie inférieure comporte en outre un logement supplémentaire pour recevoir l'extrémité d'une latte inférieure.Advantageously, the lower part further comprises an additional housing for receiving the end of a lower batten.

Avantageusement, le dispositif selon l'invention comporte en outre un plateau d'appui pour un matelas fixé à la partie supérieure.Advantageously, the device according to the invention further comprises a support plate for a mattress attached to the upper part.

De préférence, le plateau d'appui comporte une paire d'ouïes permettant l'aération du couchage. Le plateau d'appui présente également une élasticité verticale améliorant le confort du couchage.Preferably, the support plate comprises a pair of gills for aeration of the coating. The support plate also has a vertical elasticity improving the comfort of sleeping.

Avantageusement, le dispositif selon l'invention comporte en outre un boitier de logement de lattes fixé à la partie supérieure du dispositif, de manière à loger les extrémités de lattes s'étendant selon une direction sensiblement orthogonale au deuxième plan de symétrie.Advantageously, the device according to the invention further comprises a lath housing housing fixed to the upper part of the device, so as to accommodate the lath ends extending in a direction substantially orthogonal to the second plane of symmetry.

A l'aide des figures 1 à 3 , on va tout d'abord décrire un premier mode de réalisation d'un dispositif de suspension monobloc 10 conforme à la présente invention.With the help of Figures 1 to 3 Firstly, a first embodiment of a monobloc suspension device 10 according to the present invention will be described.

Le dispositif de suspension 10 représenté sur les figures 1 à 3 est un embout de lattes qui est destiné à être fixé à un long pan d'un cadre de sommier de lattes (non représenté ici).The suspension device 10 shown on the Figures 1 to 3 is a slat mouthpiece which is intended to be attached to a long pan of a lath slatted frame (not shown here).

En se référant à la figure 1 , on constate que le dispositif de suspension 10 comporte une partie supérieure 12 destinée à supporter un couchage. Dans l'exemple représenté ici, le dispositif de suspension 10 est muni d'un boitier de logement de lattes 14 comprenant deux logements 16,18 aptes à recevoir les extrémités de deux lattes (non représentées ici).Referring to the figure 1 it is found that the suspension device 10 has an upper portion 12 for supporting a coating. In the example shown here, the suspension device 10 is provided with a slat-housing case 14 comprising two recesses 16,18 adapted to receive the ends of two slats (not shown here).

Au demeurant, on définit une direction longitudinale DL du dispositif de suspension comme étant celle perpendiculaire au premier plan de symétrie P1, la direction longitudinale DL étant parallèle à la direction du long pan lorsque le dispositif de suspension formant embout y est fixé.Moreover, a longitudinal direction DL of the suspension device is defined to be that perpendicular to the first plane of symmetry P1 , the longitudinal direction DL being parallel to the direction of the long pan when the hanger device is attached thereto.

On définit également une direction transversale DT du dispositif de suspension 10 comme étant celle perpendiculaire au deuxième plan de symétrie P2, la direction transversale DT étant parallèle à la direction d'insertion des lattes dans les logements du boitier 14. La direction longitudinale DL est évidemment orthogonale à la direction transversale DT.A transverse direction DT of the suspension device 10 is also defined as that perpendicular to the second plane of symmetry P2 , the transverse direction DT being parallel to the direction of insertion of the slats in the housing of the housing 14 . The longitudinal direction DL is obviously orthogonal to the transverse direction DT .

En lieu et place du boitier de logement 14, on peut aussi munir le dispositif de suspension 10 d'un plateau d'appui destiné à supporter un couchage, tel un matelas. Un tel plateau d'appui sera décrit ci-après en référence au deuxième mode de réalisation de l'invention.In place of the housing housing 14 , it can also provide the suspension device 10 of a support plate for supporting a coating, such as a mattress. Such a support plate will be described hereinafter with reference to the second embodiment of the invention.

Le dispositif de suspension 10 comporte en outre une partie inférieure 20 destinée à être fixée au sommier, de préférence mais non nécessairement à des tenons fixés au long pan du cadre du sommier.The suspension device 10 further comprises a lower portion 20 intended to be fixed to the bed base, preferably but not necessarily to tenons fixed to the long pan of the bed frame.

Pour ce faire, la partie inférieure 20 est pourvue de moyens d'ancrage constitués par une paire de manchons 24, 26 destinés à être fixés aux tenons.To do this, the lower portion 20 is provided with anchoring means consisting of a pair of sleeves 24, 26 for attachment to the tenons.

Comme on le voit sur les figures 1 et 2 , la partie inférieure 20 comporte en outre un logement supplémentaire 27 pour une troisième latte (non représentée ici).As we see on the figures 1 and 2 , the lower portion 20 further comprises an additional housing 27 for a third slat (not shown here).

Par ailleurs, le dispositif de suspension 10 comporte en outre une partie intermédiaire 28 constituée par des éléments de suspension présentant un premier plan de symétrie P1 et un deuxième plan de symétrie P2, les plans de symétrie P1, P2 étant orthogonaux.Furthermore, the suspension device 10 further comprises an intermediate portion 28 constituted by suspension elements having a first plane of symmetry P1 and a second plane of symmetry P2 , the symmetry planes P1 , P2 being orthogonal.

Les éléments de suspension 30 comportent une paire de parois de suspension élastiques externes 32,34 qui sont sensiblement symétriques par rapport au premier plan de symétrie P1.The suspension members 30 comprise a pair of outer resilient suspension walls 32,34 which are substantially symmetrical with respect to the first plane of symmetry P1 .

En se référant à la figure 1 , on voit bien que chacune des parois de suspension externes 32,34 présente une ligne courbe moyenne C s'étendant dans le deuxième plan de symétrie.Referring to the figure 1 it can clearly be seen that each of the external suspension walls 32, 34 has an average curved line C extending in the second plane of symmetry.

Par ailleurs, chacune des parois de suspension externes 32,34 présente une première extrémité 32a,34a fixée à la partie supérieure 12, et une seconde extrémité 32b,34b fixée à la partie inférieure 20.Furthermore, each of the outer suspension walls 32,34 has a first end 32a, 34a fixed to the upper portion 12 and a second end 32b, 34b attached to the lower portion 20.

Qui plus est, chacune des parois de suspension externes 32,34 est apte à se plier, lorsqu'une charge sensiblement verticale est appliquée au dispositif de suspension, selon une ligne de pliage L1, L2 sensiblement orthogonale au deuxième plan de symétrie P2.Moreover, each of the outer suspension walls 32, 34 is able to bend, when a substantially vertical load is applied to the suspension device, along a fold line L1 , L2 substantially orthogonal to the second plane of symmetry P2 .

Pour ce faire, chacune des parois de suspension externes 32,34 comporte une portion coudée 36,38 définissant la ligne de pliage L1, L2 correspondante.To do this, each of the external suspension walls 32, 34 has a bent portion 36, 38 defining the corresponding fold line L1 , L2 .

Comme on le voit bien sur les figures 1 et 2 , les portions coudées 36 et 38 s'ouvrent vers une intersection A des premier et deuxième plans de symétries P1, P2.As can be seen from the figures 1 and 2 the angled portions 36 and 38 open towards an intersection A of the first and second planes of symmetries P1 , P2 .

De préférence, la ligne de pliage L1, L2 de chacune des parois de suspension externes 32,34 est située sensiblement à mi-distance des parties inférieure 20 et supérieure 12 du dispositif 10.Preferably the folding line L1, L2 of each of the outer suspension walls 32,34 is located substantially midway between the lower 20 and upper portions 12 of the device 10.

Chacune des portions coudées 36,38 comporte une paire de bras 36a, 36b, 38a, 38b, qui sont reliés entre eux par l'une de leurs extrémités d'une part, et aux parties inférieure 20 et supérieure 12 du dispositif de suspension 10 d'autre part.Each of the bent portions 36,38 includes a pair of arms 36a, 36b, 38a, 38b, which are interconnected by one of their ends on the one hand, and the lower 20 and upper portions 12 of the hanger 10 on the other hand.

Conformément à la présente invention, les éléments de suspension 30 du dispositif de suspension 10 comporte en outre une paire de parois de suspension élastiques internes 40, 42, qui sont symétriques par rapport au premier plan de symétrie P1.According to the present invention, the suspension members 30 of the suspension device 10 further comprises a pair of internal elastic suspension walls 40 , 42 which are symmetrical with respect to the first plane of symmetry P1 .

A l'aide de la figure 2 , on conçoit que les première et seconde parois de suspension internes 40,42 de ladite paire soient disposées dans un volume délimité par les parois de suspension externes 32,34.Using the figure 2 it is conceivable that the first and second internal suspension walls 40 , 42 of said pair are disposed in a volume delimited by the external suspension walls 32, 34 .

Comme on le voit sur les figures 2 et 3 , la largeur des parois de suspension internes 40,42 est sensiblement égale à la largeur des parois de suspension externes 32,34. As we see on the Figures 2 and 3 the width of the inner suspension walls 40,42 is substantially equal to the width of the outer suspension walls 32,34.

Par ailleurs, chacune des parois de suspension internes 40,42 présente une première extrémité 40a,42a fixée à la partie supérieure 12, et une seconde extrémité 40b,42b fixée à la partie inférieure 20.Moreover, each of the internal suspension walls 40, 42 has a first end 40a, 42a fixed to the upper part 12 , and a second end 40b, 42b fixed to the lower part 20 .

Les secondes extrémités 40b,42b sont reliées entre elles par une membrane souple 41 s'étendant selon une direction longitudinale du dispositif 10.The second ends 40b, 42b are interconnected by a flexible membrane 41 extending in a longitudinal direction of the device 10 .

Comme on le voit sur la figure 1 , les premières extrémités 32a,34a des parois de suspension externes 32,34, coïncident avec les premières extrémités 40a,42a des parois de suspension internes 40,42, grâce à quoi les parois de suspension externes 32,34 peuvent pousser verticalement les parois de suspension internes 40,42 lorsque le dispositif de suspension est chargé verticalement.As we see on the figure 1 the first ends 32a, 34a of the outer suspension walls 32,34, coincide with the first ends 40a, 42a of the inner suspension walls 40,42, whereby the external suspension walls 32,34 can push the walls of the walls vertically. internal suspension 40,42 when the suspension device is vertically loaded.

Chacune des parois de suspension internes 40,42 présente au moins une ligne courbe moyenne s'étendant dans le deuxième plan de symétrie P2. Dans cet exemple, la ligne courbe moyenne de la paroi de suspension interne 40 présente sensiblement la forme d'un « Σ ».Each of the inner suspension walls 40 , 42 has at least one mean curved line extending in the second plane of symmetry P2 . In this example, the average curved line of the inner suspension wall 40 has substantially the shape of a "Σ".

De manière particulièrement avantageuse, chacune des parois de suspension internes 40,42 est apte à se plier selon trois lignes de pliage M1, M2 et M3 distinctes, qui sont sensiblement orthogonales au deuxième plan de symétrie P2.Particularly advantageously, each of the internal suspension walls 40 , 42 is able to bend along three distinct fold lines M1 , M2 and M3 , which are substantially orthogonal to the second plane of symmetry P2 .

Pour ce faire, chacune des parois de suspension internes 40,42, considérée verticalement depuis la partie supérieure 12 vers la partie inférieure 20, comporte successivement des première, deuxième et troisième portions coudées référencées 401,402 et 403 (pour la première paroi de suspension interne 40) d'une part, et 421,422 et 423 (pour la seconde paroi de suspension interne 42) d'autre part, lesdites portions coudées définissant respectivement les première, deuxième et troisième lignes de pliage M1, M2, M3 d'une part, et les première, deuxième et troisième lignes de pliage N1, N2 et N3 d'autre part.To do this, each of the internal suspension walls 40,42, considered vertically from the upper part 12 to the lower part 20 , comprises successively first, second and third bent portions referenced 401,402 and 403 (for the first internal suspension wall 40 ) on the one hand, and 421,422 and 423 (for the second inner suspension wall 42) on the other hand, bent portions respectively defining the first, second and third fold lines M1 , M2 , M3 on the one hand, and the first, second and third fold lines N1 , N2 and N3 on the other hand.

Comme on le voit bien à l'aide des figures 1 et 2 , pour chacune des parois internes 40,42, les première et troisième portions coudées 401,403,421,423 s'ouvrent vers l'intersection A des premier et deuxième plans de symétrie P1, P2, tandis que la deuxième portion coudée 402,422 s'ouvre vers une direction opposée, à savoir vers la paroi de suspension externe la plus proche de ladite paroi interne.As can be seen with the help of figures 1 and 2 for each of the inner walls 40,42, the first and third angled portions 401,403,421,423 open towards the intersection A of the first and second planes of symmetry P1 , P2 , while the second bent portion 402,422 opens towards an opposite direction , ie towards the outer suspension wall closest to said inner wall.

En outre, pour chacune des parois internes 40,42, la première portion coudée 401,421 présente deux bras référencés respectivement 401a,401b et 421a,421b qui sont sensiblement de même longueur, cette longueur étant considérée dans le deuxième plan de symétrie P2.In addition, for each of the internal walls 40,42 , the first bent portion 401,421 has two arms respectively referenced 401a, 401b and 421a, 421b which are substantially the same length, this length being considered in the second plane of symmetry P2 .

De manière similaire, la deuxième portion coudée 402 de la première paroi de suspension interne 40, comporte une paire de bras 402a,402b tandis que la troisième portion coudée 403 comporte une paire de bras 403a,403b. Aussi, la deuxième portion coudée 422 de la seconde paroi de suspension interne 42 comporte une paire de bras 422a,422b, tandis que la troisième portion coudée 423 comporte une paire de bras 423a,423b. On constate en l'espèce que les bras 401b et 402a sont identiques, tout comme les bras 403a et 402b, 421b et 422a, ainsi que 423a et 422b.Similarly, the second bent portion 402 of the first inner suspension wall 40 has a pair of arms 402a, 402b while the third bent portion 403 has a pair of arms 403a, 403b . Also, the second bent portion 422 of the second inner suspension wall 42 includes a pair of arms 422a, 422b , while the third bent portion 423 includes a pair of arms 423a, 423b . In the present case, it can be seen that the arms 401b and 402a are identical, as are the arms 403a and 402b , 421b and 422a , as well as 423a and 422b .

De préférence, pour chacune des parois de suspension internes 40,42, considérées dans le deuxième plan de symétrie P2, le dispositif de suspension 10 étant au repos, la distance D entre la première extrémité 40a de la paroi de suspension interne 40 et la deuxième ligne de pliage M2 est sensiblement égale au double de la distance d mesurée entre la deuxième ligne de pliage M2 et la seconde extrémité 40b de la paroi de suspension interne 40 ce rapport de distance contribue à la progressivité de la raideur comme on l'a déjà mentionné ci-dessus.Preferably, for each of the internal suspension walls 40,42 , considered in the second plane of symmetry P2 , the suspension device 10 being at rest, the distance D between the first end 40a of the inner suspension wall 40 and the second M2 fold line is substantially equal to twice the distance d measured between the second fold line M2 and the second end 40b of the inner suspension wall 40 this distance ratio contributes to the progressiveness of the stiffness as it has already been mentioned above.

On va maintenant décrire plus en détail le principe de fonctionnement du dispositif de suspension 10 selon l'invention.We will now describe in more detail the operating principle of the suspension device 10 according to the invention.

Lorsqu'une charge est appliquée sur la partie supérieure 12 du dispositif 10 selon une direction sensiblement verticale, les parois de suspension internes et externes plient le long de leurs lignes de pliage respectives de sorte que la partie supérieure 12 tend à se rapprocher de la partie inférieure 20.When a load is applied to the upper portion 12 of the device 10 in a substantially vertical direction, the inner and outer suspension walls fold along their fold lines. respective ones so that the upper part 12 tends to approach the lower part 20 .

Qui plus est, lors du pliage du dispositif 10, les bras 36a et 38a des portions de suspension externes 36, 38 tendent les bras 401a, 421a des premières portions coudées 401,421, créant ainsi un couplage mécanique entre les portions de suspension internes et externes.Moreover, during the folding of the device 10 , the arms 36a and 38a of the outer suspension portions 36 , 38 tend the arms 401a , 421a of the first bent portions 401,421, thereby creating a mechanical coupling between the inner and outer suspension portions.

Lors du pliage du dispositif de suspension 10, les bras 401a, 401b, 421a,421b des premières portions coudées 401,421 tendent à s'empiler les uns sur les autres, ce qui a pour conséquence d'augmenter progressivement la raideur globale du dispositif de suspension 10.During folding of the suspension device 10 , the arms 401a , 401b , 421a, 421b of the first bent portions 401, 421 tend to stack one on top of the other, which has the consequence of gradually increasing the overall stiffness of the suspension device. 10 .

Grâce à cette conformation avantageuse, les éléments de suspension 30 présentent une raideur progressive selon une direction verticale.With this advantageous configuration, the suspension elements 30 have a progressive stiffness in a vertical direction.

A l'aide des figures 4 à 7 , on va maintenant décrire un exemple comparatif.With the help of Figures 4 to 7 a comparative example will now be described.

Le dispositif de suspension 100 est destiné à être fixé à une latte souple du sommier afin de supporter un couchage, tel un matelas.The suspension device 100 is intended to be fixed to a flexible lath of the bed base to support a bedding, such as a mattress.

En se référant aux figures 4 et 6 , on constate que le dispositif de suspension 100 comporte une partie supérieure 120 destinée à supporter un couchage (non représenté ici). Dans l'exemple représenté ici, le dispositif de suspension 100 est muni d'un plateau d'appui 140 pour supporter le couchage.Referring to figures 4 and 6 it is found that the suspension device 100 has an upper portion 120 for supporting a coating (not shown here). In the example shown here, the suspension device 100 is provided with a support plate 140 to support the coating.

En lieu et place du plateau d'appui 140, on peut aussi munir le dispositif de suspension 100 d'un boitier de logement de lattes tel que décrit dans le premier mode de réalisation de l'invention, une telle configuration étant représentée à la figure 7 .Instead of the support plate 140 , it is also possible to provide the suspension device 100 with a slatted housing as described in the first embodiment of the invention, such a configuration being shown in FIG. figure 7 .

Le dispositif de suspension 100 comporte en outre une partie inférieure 200 destinée à être fixée de préférence à une latte souple. Pour ce faire, la partie inférieure comporte notamment un crochet de fixation 210, mieux visible sur la figure 5 .The suspension device 100 further comprises a lower portion 200 intended to be fixed preferably to a flexible lath. To do this, the lower part comprises in particular a fixing hook 210 , better visible on the figure 5 .

Par ailleurs, le dispositif de suspension 100 comporte en outre une partie intermédiaire 280 constitués par des éléments de suspension 300 présentant un premier plan de symétrie Q1 et un deuxième plan de symétrie Q2, les plans de symétrie Q1, Q2 étant orthogonaux.Furthermore, the suspension device 100 further comprises an intermediate portion 280 constituted by suspension elements 300 having a first plane of symmetry Q1 and a second plane of symmetry Q2 , the symmetry planes Q1 , Q2 being orthogonal.

Les éléments de suspension 300 comportent une paire de parois de suspension élastiques externes 320,340 qui sont sensiblement symétriques par rapport au premier plan de symétrie Q1.The suspension members 300 comprise a pair of external resilient suspension walls 320, 340 which are substantially symmetrical with respect to the first plane of symmetry Q1 .

En se référant à la figure 4 , on voit que chacune des parois de suspension externes 320,340 présente une ligne courbe moyenne en forme de « C » s'étendant dans le deuxième plan de symétrie Q2.Referring to the figure 4 it can be seen that each of the external suspension walls 320, 340 has a mean C-shaped curved line extending in the second plane of symmetry Q2 .

Par ailleurs, chacune des parois de suspension externes 320,340 présente une première extrémité 320a,340a fixée à la partie supérieure 120, et une seconde extrémité 320b,340b fixée à la partie inférieure 200.Furthermore, each of the outer suspension walls 320, 340 has a first end 320a, 340a attached to the upper part 120 , and a second end 320b, 340b fixed to the lower part 200 .

En outre, lorsqu'une charge est appliquée verticalement au dispositif de suspension 100, chacune des parois de suspension externes 320,340 est apte à se plier, selon une ligne de pliage L1, L2 sensiblement orthogonale au deuxième plan de symétrie Q2.In addition, when a load is applied vertically to the suspension device 100 , each of the external suspension walls 320, 340 is able to bend, along a fold line L1 , L2 substantially orthogonal to the second plane of symmetry Q2 .

Par ailleurs, la ligne de pliage L1, L2 de chacune des parois de suspension externes 320,340 est disposée à mi-distance des parties inférieure 200 et supérieure 120 du dispositif de suspension 100.Furthermore, the fold line L1 , L2 of each of the external suspension walls 320, 340 is disposed midway between the lower 200 and upper 120 parts of the suspension device 100 .

Conformément à la présente invention, les éléments de suspension 300 du dispositif de suspension 100 comporte en outre au moins des première et seconde parois de suspension élastiques internes 500, 520 qui sont sensiblement symétriques par rapport au premier plan de symétrie Q1.According to the present invention, the suspension members 300 of the suspension device 100 further include at least first and second inner resilient suspension walls 500 , 520 which are substantially symmetrical with respect to the first plane of symmetry Q1 .

La première paroi de suspension élastique 500 comporte une première extrémité 500a reliée à la partie supérieure 120 du dispositif de suspension 100 et une seconde extrémité 500b reliée à sa partie inférieure 200. De manière similaire, la seconde paroi de suspension 520 comporte une première extrémité 520a reliée à la partie supérieure 120 et une seconde extrémité reliée à la partie inférieure 200.The first elastic suspension wall 500 has a first end 500a connected to the upper part 120 of the suspension device 100 and a second end 500b connected to its lower part 200 . Similarly, the second suspension wall 520 has a first end 520a connected to the upper part 120 and a second end connected to the lower part 200 .

A l'aide de la figure 4 , on conçoit que chacune des parois de suspension internes 500,520 présente au moins une ligne courbe s'étendant dans le deuxième plan de symétrie Q2.Using the figure 4 it is conceivable that each of the inner suspension walls 500 , 520 has at least one curved line extending in the second plane of symmetry Q2 .

De manière particulièrement avantageuse, la paroi de suspension interne 500 est apte à se plier selon trois lignes de pliage T1, T2, T3 distinctes, tandis que la paroi de suspension interne 520 est apte à se plier selon trois lignes de pliage U1, U2, U3 distinctes.Particularly advantageously, the inner suspension wall 500 is able to bend along three distinct fold lines T1 , T2 , T3 , while the inner suspension wall 520 is able to bend along three folding lines U1 , U2 , U3 distinct.

Pour ce faire, chacune des parois de suspension internes 500,520, considérée verticalement depuis la partie supérieure 120 vers la partie inférieure 200, comporte successivement des première, deuxième et troisième portions coudées référencées 501,502 et 503 pour la paroi de suspension interne 500, et 521,522 et 523 pour la paroi de suspension interne 520, lesdites portions coudées définissant respectivement les première, deuxième et troisième lignes de pliage T1,T2,T3 d'une part, et les première, deuxième et troisième lignes de pliage U1, U2,U3 d'autre part.To do this, each of the internal suspension walls 500, 520, considered vertically from the upper part 120 to the lower part 200 , comprises successively first, second and third bent portions referenced 501, 502 and 503 for the inner suspension wall 500 , and 521 , 522 and 523 for the inner suspension wall 520 , said bent portions respectively defining the first, second and third fold lines T1, T2, T3 on the one hand, and the first, second and third fold lines U1 , U2, U3 of somewhere else.

Comme on le voit bien sur la figure 4 , pour chacune des parois internes 500,520, les premières et troisièmes portions coudées 501,503,521,523 s'ouvrent vers la paroi de suspension externe la plus proche de ladite paroi interne, tandis que la deuxième portion coudée 502,522 s'ouvre vers une direction opposée, à savoir vers une intersection B des premier et deuxième plans de symétrie Q1 et Q2.As can be seen from the figure 4 for each of the inner walls 500 , 520 , the first and third angled portions 501 , 503 , 521 , 523 open towards the outer suspension wall nearest to said inner wall, while the second elbow portion 502, 522 opens towards an opposite direction, namely towards an intersection B of the first and second planes of symmetry Q1 and Q2 .

Par ailleurs, les parois de suspensions internes 500,520 sont fixées entre elles le long de leurs premières T1, U1 et troisièmes T3, U3 lignes de pliage.Furthermore, the inner suspension walls 500 , 520 are fixed together along their first T1 , U1 and third T3 , U3 fold lines.

De manière particulièrement avantageuse, chacune des parois de suspension internes 500,520 est reliée à la paroi de suspension externe la plus proche par l'intermédiaire d'une paroi formant tube 540,560 s'étendant selon une direction orthogonale au deuxième plan de symétrie Q2.Particularly advantageously, each of the inner suspension walls 500 , 520 is connected to the nearest outer suspension wall via a tube wall 540, 560 extending in a direction orthogonal to the second plane of symmetry Q2 .

Plus précisément, chaque paroi formant tube 540,560 est fixée à la paroi de suspension interne 500,520 le long de la deuxième ligne de pliage T2, U2, et est fixée à la paroi de suspension externe 320,340 correspondante le long de la ligne de pliage de ladite paroi de suspension externe 320,340.Specifically, each tube wall 540, 560 is attached to the inner suspension wall 500 , 520 along the second fold line T2 , U2 , and is attached to the corresponding outer suspension wall 320, 340 along the fold line of said wall. external suspension 320,340 .

Ainsi, les éléments de suspension 300 présentent avantageusement une structure en nid d'abeilles.Thus, the suspension elements 300 advantageously have a honeycomb structure.

Par ailleurs, comme on le voit bien à l'aide des figures 4 et 7 , les éléments de suspension 300 sont inscrits dans un volume sphérique.Moreover, as we can see with the help of figures 4 and 7 the suspension elements 300 are inscribed in a spherical volume.

La figure 6 montre le dispositif de suspension 100 équipé du plateau d'appui 140, tandis que la figure 7 montre le dispositif de suspension 100 équipé du boitier de logement de lattes 700.The figure 6 shows the suspension device 100 equipped with the support plate 140 , while the figure 7 shows the suspension device 100 equipped with the slat housing case 700.

Le plateau d'appui 140 présente une forme quadrangulaire. Il comprend deux bords latéraux longitudinaux opposés 142, 144 surélevés ainsi que deux bords transversaux opposés 146,148, également surélevés par rapport à une partie centrale 150 présentant un orifice circulaire dans lequel vient se fixer la partie supérieure 120 du dispositif de suspension.The support plate 140 has a quadrangular shape. It comprises two opposite longitudinal lateral edges 142 , 144 raised as well as two opposite transverse edges 146 , 148 , also raised with respect to a central portion 150 having a circular orifice in which is fixed the upper part 120 of the suspension device.

De manière avantageuse, le plateau d'appui 140 présente également une paire d'ouïes 152,154 permettant l'aération du matelas.Advantageously, the support plate 140 also has a pair of louvers 152,154 for aeration of the mattress.

De surcroît les bords latéraux 146,148, du fait de la présence des ouïes, présentent de manière avantageuse une élasticité verticale qui améliore encore la souplesse du dispositif de suspension 100 selon l'invention.In addition, the side edges 146 , 148 , because of the presence of the gills, advantageously have a vertical elasticity which further improves the flexibility of the suspension device 100 according to the invention.

Comme on l'a déjà mentionné, un tel plateau peut être utilisé avec tous les modes de réalisation du dispositif de suspension.As already mentioned, such a tray can be used with all embodiments of the suspension device.

A l'aide des figures 8 à 10 , on va maintenant décrire un autre exemple comparatif.With the help of Figures 8 to 10 we will now describe another comparative example.

Ce dispositif de suspension 1000 est similaire à celui du deuxième mode de réalisation sauf pour ce qui concerne la structure des parois de suspension internes. On s'attachera donc à décrire les parois de suspension internes 1100, 1200 du dispositif de suspension 1000. Pour le reste, il convient de se reporter à la description du deuxième mode de réalisation qui précède.This suspension device 1000 is similar to that of the second embodiment except for the structure of the inner suspension walls. It will therefore be attempted to describe the internal suspension walls 1100 , 1200 of the suspension device 1000 . For the rest, it is necessary to refer to the description of the second embodiment above.

Les parois de suspension élastiques internes 1100,1200 sont symétriques par rapport à un premier plan de symétrie R1 des éléments de suspension 1050 du dispositif 1000, chacune des parois de suspension internes 1100,1200 présentant une ligne courbe moyenne s'étendant dans un deuxième plan de symétrie R2 des éléments de suspension 1050 du dispositif 1000. Tout comme dans les premier et deuxième modes de réalisation, les plans de symétrie R1 et R2 sont orthogonaux.The internal elastic suspension walls 1100 , 1200 are symmetrical with respect to a first plane of symmetry R1 of the suspension elements 1050 of the device 1000 , each of the internal suspension walls 1100 , 1200 having a mean curve line extending in a second plane of symmetry R2 of the suspension elements 1050 of the device 1000 . As in the first and second embodiments, the symmetry planes R1 and R2 are orthogonal.

En outre, la paroi de suspension interne 1100 est apte à se plier selon trois lignes de pliage V1, V2, V3 distinctes, tandis que l'autre paroi de suspension interne 1200 est apte à se plier selon trois lignes de pliage W1, W2, W3 distinctes, ces lignes de pliage étant sensiblement orthogonales au deuxième plan de symétrie.In addition, the inner suspension wall 1100 is able to bend along three distinct fold lines V1 , V2 , V3 , while the other inner suspension wall 1200 is able to bend along three folding lines W1 , W2 , W3 distinct, these fold lines being substantially orthogonal to the second plane of symmetry.

Contrairement au premier exemple comparatif, les parois internes ne sont pas reliées aux parois de suspension externes 1300,1400 par une paroi formant tube.Unlike the first comparative example, the inner walls are not connected to the outer suspension walls 1300, 1400 by a tube wall.

En revanche, les parois de suspension internes sont fixées entre elles par l'intermédiaire d'un manchon souple 1500 s'étendant selon une direction orthogonale au deuxième plan de symétrie.On the other hand, the internal suspension walls are fixed together by means of a flexible sleeve 1500 extending in a direction orthogonal to the second plane of symmetry.

Ce manchon souple 1500 permet de coupler mécaniquement les parois de suspension internes 1100,1200 de sorte que les efforts subis par le dispositif 1000 lorsqu'une charge verticale est appliquée sont avantageusement répartis dans la structure cylindrique du manchon 1500.This flexible sleeve 1500 makes it possible to mechanically couple the internal suspension walls 1100 , 1200 so that the forces experienced by the device 1000 when a vertical load is applied are advantageously distributed in the cylindrical structure of the sleeve 1500 .

Conformément à l'invention, le dispositif de suspension 10 est monobloc. De préférence, mais non exclusivement, il est moulé en une seule pièce et réalisé de préférence dans un matériau souple du type caoutchouc vulcanisé, polyuréthane souple, caoutchouc thermoplastique de dureté comprise de préférence entre 25 shore A et 70 shore D.According to the invention, the suspension device 10 is in one piece. Preferably, but not exclusively, it is molded in one piece and preferably made of a flexible material of vulcanized rubber, flexible polyurethane, thermoplastic rubber of hardness preferably between 25 Shore A and 70 Shore D.

De préférence, le plateau d'appui et le boîtier du logement sont des éléments apportés structurellement distincts du dispositif de suspension, grâce à quoi il est possible de les interchanger.Preferably, the support plate and the housing of the housing are structurally distinct elements of the suspension device, whereby it is possible to interchange them.

Au surplus, la progressivité de la raideur du dispositif de suspension peut encore être améliorée en prévoyant une épaisseur croissante des parois de suspension internes et/ou externes, étant entendu que la croissance de l'épaisseur est considérée depuis la partie supérieure vers la partie inférieure du dispositif de suspension selon l'invention.In addition, the progressivity of the stiffness of the suspension device can be further improved by providing an increasing thickness of the inner and / or outer suspension walls, it being understood that the growth of the thickness is considered from the top to the bottom. of the suspension device according to the invention.

La figure 1 montre que les bras 403a,403b,423a,423b des troisièmes portions coudées 403,423 des première et seconde parois de suspension 40,42 sont plus épaisses que les bras 401a,401b,421a,421b des premières portions coudées 401,421.The figure 1 shows that the arms 403a, 403b, 423a, 423b of the third bent portions 403,423 of the first and second suspension walls 40,42 are thicker than the arms 401a, 401b, 421a, 421b of the first bent portions 401,421 .

Aussi, pour chaque portion coudée, 401,402,403,421,422,423, le bras le plus proche de la partie supérieure 12 du dispositif de suspension est plus épaisse que le bras le plus proche de la partie inférieure 20.Also, for each bent portion, 401 , 402 , 403 , 421 , 422 , 423 , the arm closest to the upper portion 12 of the suspension device is thicker than the arm closest to the lower portion 20 .
