Description

L'invention concerne un dispositif de suspension universel pour literie ou pour siège, disposé entre une surface d'appui et un élément de rembourrage.The invention relates to a universal suspension device for bedding or for a seat, arranged between a support surface and a cushioning element.

Elle concerne plus précisément un dispositif unitaire de suspension pour un sommier du type multi-éléments, ce dispositif étant destiné à être interposé entre une plate-forme déterminant une surface d'appui et un élément de rembourrage tel qu'un matelas, et comportant une embase destinée à être fixée sur un élément de plate-forme, une structure de suspension fixée sur l'embase et un plateau porté par la structure de suspension et servant de support à l'élément de rembourrage, ladite structure de suspension étant de révolution autour d'un axe vertical.It relates more specifically to a unitary suspension device for a bed base of the multi-element type, this device being intended to be interposed between a platform determining a bearing surface and a cushioning element such as a mattress, and having a base intended to be fixed on a platform element, a suspension structure fixed on the base and a plate carried by the suspension structure and serving as a support for the cushioning element, said suspension structure being of revolution around a vertical axis.

En général, ces dispositifs unitaires de suspension sont disposés en rangées et colonnes et fixées sur des traverses rigides constituant la plate-forme. D'habitude, ces éléments sont symétriques par rapport à un plan médian transversal et par rapport à un plan médian longitudinal, et la dureté n'est pas homogène selon l'inclinaison subie par le plateau.In general, these unitary suspension devices are arranged in rows and columns and fixed on rigid sleepers constituting the platform. Usually, these elements are symmetrical with respect to a transverse median plane and with respect to a longitudinal median plane, and the hardness is not uniform according to the inclination undergone by the plate.

WO 01 15572 décrit un dispositif unitaire de suspension comportant une embase et une structure de suspension, dans lequel la structure de suspension, seule et au repos, se présente sous la forme d'un anneau central à partir duquel divergent une pluralité de bras radiaux élastiques. Les extrémités de ces bras comportent des moyens de fixation sur un anneau de l'embase. Après le montage de ces extrémités de bras sur l'anneau de l'embase les bras se présentent sous la forme de secteurs d'une sphère, séparés par des ouvertures latérales, mais ils sont soumis à des contraintes élastiques, et en cas de rupture de ces attaches, ils doivent reprendre une position radiale.WO 01 15572 discloses a unitary suspension device comprising a base and a suspension structure, in which the suspension structure, alone and at rest, is in the form of a central ring from which a plurality of elastic radial arms diverge; . The ends of these arms comprise fixing means on a ring of the base. After mounting these arm ends on the ring of the base the arms are in the form of sectors of a sphere, separated by lateral openings, but they are subjected to elastic stresses, and in case of rupture these fasteners, they must take a radial position.

DE 29 903 423 qui représente l'état de la technique le plus proche de l'invention a déjà prévu une structure de suspension évidée de forme sphérique réalisée dans une mousse d'un matériau synthétique élastique qui comporte à ses extrémités supérieure et inférieure des trous pour la fixation par clippage de l'embase et du plateau. Après le montage, la structure de suspension est normalement étanche à l'air, et fonctionne à la manière d'un ballon. Le problème qui se pose concerne l'étanchéité au niveau de ces trous.DE 29 903 423, which represents the state of the art closest to the invention, has already provided a spherical shaped hollow suspension structure made of a foam of an elastic synthetic material which has holes at its upper and lower ends. for fixing by clipping of the base and the plate. After mounting, the suspension structure is normally airtight, and operates like a balloon. The problem that arises is the sealing at these holes.

Partant de cet état de la technique, l'invention propose un nouveau type de suspension dans lequel il ne pose pas de question d'étanchéité à l'air.Based on this state of the art, the invention proposes a new type of suspension in which it does not pose a question of airtightness.

L'invention atteint son but par le fait que la structure de suspension seule se présente au repos sous la forme d'une sphère évidée et monobloc comportant une pluralité de secteurs séparés par des ouvertures latérales et réalisée en un matériau de synthèse souple ou en caoutchouc vulcanisé dont la dureté est comprise entre 40 shores A et 70 shores D.The invention achieves its object by the fact that the suspension structure alone is at rest in the form of a hollow and monobloc sphere having a plurality of sectors separated by lateral openings and made of a flexible synthetic material or rubber vulcanized hardness of which is between 40 A shores and 70 D scores.

Ainsi, seule la paroi de la structure de suspension participe aux efforts de compression et de flexion, en cas de charge, et l'intérieur de la structure est avantageusement soumis à la pression atmosphérique.Thus, only the wall of the suspension structure participates in the compression and bending forces, in the case of a load, and the inside of the structure is advantageously subjected to atmospheric pressure.

Afin de faciliter le positionnement du plateau par rapport à l'embase et à l'élément de plate-forme, l'embase comporte des moyens pour empêcher sa rotation par rapport à l'élément de plate-forme.In order to facilitate the positioning of the plate relative to the base and to the platform element, the base comprises means for preventing its rotation relative to the platform element.

La structure de suspension et le plateau comportent des moyens coopérants pour assurer leur liaison en traction et en rotation autour de l'axe de révolution de ladite structure de suspension. Ces moyens comportent de préférence un système de fixation à baïonnette et un système de clippage.The suspension structure and the plate comprise cooperating means for ensuring their connection in traction and in rotation around the axis of revolution of said suspension structure. These means preferably comprise a bayonet fixing system and a clipping system.

L'embase et la structure de suspension peuvent être réalisées en une seule pièce. Elles peuvent également être réalisées en deux pièces séparées. Dans ce cas, la structure de suspension et l'embase comportent des moyens coopérants pour assurer leur liaison en traction et en rotation autour de l'axe de révolution de ladite structure de suspension.The base and the suspension structure can be made in one piece. They can also be made in two separate rooms. In this case, the suspension structure and the base comprise cooperating means to ensure their connection in traction and in rotation about the axis of revolution of said suspension structure.

La liaison entre la structure de liaison et l'embase peut être réalisée de différentes façons, soit par un système de glissière en forme de queue d'aronde et un système de clippage pour verrouiller les deux pièces entre elles après montage, soit par un système de clippage et positionnement d'un tenon dans une mortaise, soit par un système à baïonnette combiné avec un système de clippage, soit par un dispositif à pinces guidé par une glissière lors du montage, avec un dispositif de verrouillage anti-rotation qui se positionne automatiquement à la fin du montage.The link between the connecting structure and the base can be made in different ways, either by a dovetail slide system and a clipping system to lock the two parts together after assembly, or by a system of clipping and positioning a tenon in a mortise, either by a bayonet system combined with a clipping system, or by a gripper device guided by a slide during assembly, with an anti-rotation locking device which is positioned automatically at the end of editing.

Dans tous les cas, les moyens de liaison mutuelle sont formés sur les deux pièces lors du moulage de ces dernières.In all cases, the mutual connection means are formed on the two parts during molding of the latter.

La structure de suspension peut être sphérique et comporter des secteurs alternant avec des ouvertures latérales régulièrement réparties autour de l'axe de révolution de ladite structure. Les dimensions et épaisseurs de ces secteurs sont calculées en fonction de la raideur souhaitée.The suspension structure may be spherical and have sectors alternating with lateral openings regularly distributed around the axis of revolution of said structure. The dimensions and thicknesses of these sectors are calculated according to the desired stiffness.

Pour modifier la raideur de la structure de suspension, cette dernière peut comporter dans sa cavité interne un organe raidisseur amovible disposé dans son axe de révolution, ledit organe comportant avantageusement à son extrémité supérieure un bouchon qui loge dans un orifice traversant ménagé dans une tête de fixation du plateau formée à l'extrémité supérieure de la structure de suspension.To modify the stiffness of the suspension structure, the latter may comprise in its internal cavity a removable stiffening member disposed in its axis of revolution, said member advantageously having at its upper end a plug which accommodates in a through orifice formed in a head of fastening the tray formed at the upper end of the suspension structure.

Les figures 1 à 10 montrent un dispositif unitaire de suspension 1 d'un sommier multi-éléments par exemple, selon un mode préféré de réalisation de l'invention. Ce dispositif de suspension 1 est destiné à être fixé sur une traverse d'une plate-forme d'appui, non montrée sur les dessins, et comporte essentiellement trois éléments : une embase 2 destinée à être fixée sur une traverse, une structure de suspension 3 montée sur l'embase 2 et un plateau 4 supporté par la structure de suspension 3.Figures 1 to 10 show a unitary suspension device 1 of a multi-element bed base for example, according to a preferred embodiment of the invention. This suspension device 1 is intended to be fixed on a cross member of a support platform, not shown in the drawings, and comprises essentially three elements: a base 2 intended to be fixed on a cross member, a suspension structure 3 mounted on the base 2 and a plate 4 supported by the suspension structure 3.

Le plateau 4 sert de support à un élément de rembourrage, un matelas par exemple, non montré sur les dessins. Le dispositif de suspension 1 peut comporter en outre un organe raidisseur 5 qui permet de modifier la raideur du dispositif de suspension 1 selon la position de ce dernier dans le sommier. Le sommier comporte une pluralité de dispositifs de suspension disposés en rangées et colonnes juxtaposées.The tray 4 serves as support for a padding element, a mattress for example, not shown in the drawings. The suspension device 1 may further comprise a stiffening member 5 which makes it possible to modify the stiffness of the suspension device 1 according to the position of the latter in the bed base. The bed base comprises a plurality of suspension devices arranged in rows and columns juxtaposed.

L'embase 2, montrée en détail sur les figures 3 et 4, est réalisée en un matériau de synthèse rigide approprié, tel du polypropylène ou du polyamide, par moulage, ou en métal. Elle comporte un orifice central 6 permettant sa fixation au moyen d'une vis sur une traverse, et, sur sa face inférieure 2a, un téton 7 destiné à être logé dans un trou ménagé dans la traverse, afin d'empêcher la rotation de l'embase 2 après sa fixation sur la traverse. L'embase 2 comporte en outre, sur sa face supérieure 2b, deux languettes latérales 8a et 8b qui s'étendent dans une même direction parallèlement à la traverse et un trou 9 disposé au-dessus du téton 7. Les languettes 8a et 8b servent à retenir la structure de suspension 3, et le trou 9 sert à immobiliser la structure de suspension 3, notamment en rotation après le montage de cette dernière, ainsi que cela est expliqué ci-après.The base 2, shown in detail in Figures 3 and 4, is made of a suitable rigid synthetic material, such as polypropylene or polyamide, by molding, or metal. It comprises a central orifice 6 allowing its attachment by means of a screw on a cross member, and on its lower face 2a, a stud 7 intended to be housed in a hole in the crosspiece, in order to prevent rotation of the crosspiece. base 2 after its fixation on the crosses. The base 2 further comprises, on its upper face 2b, two lateral tongues 8a and 8b which extend in the same direction parallel to the cross-member and a hole 9 disposed above the stud 7. The tongues 8a and 8b serve to retain the suspension structure 3, and the hole 9 serves to immobilize the suspension structure 3, in particular in rotation after mounting thereof, as explained below.

La structure de suspension 3, montrée en détail sur les figures 5 et 6, est de révolution autour d'un axe vertical X. Elle est réalisée en un matériau de synthèse souple type TPE ou caoutchouc vulcanisé. Les duretés des matériaux sont ajustées aux charges à soutenir. Les duretés sont préférentiellement comprises entre 40 shores A et 70 shores D. La structure de suspension 3 se présente sous la forme d'une sphère qui présente trois secteurs 10a, 10b, 10c, séparés par trois ouvertures latérales 11a, 11b, 11c, régulièrement espacées autour de l'axe X. L'étendue circonférentielle des secteurs 10a, 10b, 10c et des ouvertures latérales 11a, 11b, 11c autour de l'axe de révolution X est sensiblement égale à 60°.The suspension structure 3, shown in detail in Figures 5 and 6, is of revolution about a vertical axis X. It is made of a flexible synthetic material type TPE or vulcanized rubber. The hardnesses of the materials are adjusted to the loads to be supported. The hardnesses are preferably between 40 Shore A and 70 Shore D. The suspension structure 3 is in the form of a sphere which has three sectors 10a, 10b, 10c, separated by three lateral openings 11a, 11b, 11c, regularly spaced around the axis X. The circumferential extent of the sectors 10a, 10b, 10c and lateral openings 11a, 11b, 11c around the axis of revolution X is substantially equal to 60 °.

Les secteurs 10a, 10b, 10c relient une tête de fixation 12 du plateau 4, située dans la zone supérieure de la structure de suspension 3, à une calotte 13 située dans sa zone inférieure. La calotte 13 est globalement plane et présente sur sa face supérieure une zone plus épaisse 14 qui s'étend entre le secteur 10a et l'ouverture opposée 11a. Une languette 15 est réalisée au moyen d'une fente en U dans la zone plus épaisse 14. Un téton 16 est formé sur la face inférieure de la languette 15. La largeur de la zone plus épaisse 14 est égale à la distance qui sépare les deux languettes 8a, 8b de l'embase 2. L'épaisseur de la calotte 13 à l'extérieur de la zone plus épaisse 14 est égale à la distance séparant les languettes 8a, 8b de l'embase 2 de la face supérieure 2b de cette embase. Pour monter la structure de suspension 3 sur l'embase 2, on présente les ouvertures 11b, 11c devant les extrémités des languettes 8a et 8b, et on fait coulisser la calotte 13 sous les languettes 8a et 8b. Les languettes 8a et 8b sont guidées par les bords de la zone plus épaisse 14.The sectors 10a, 10b, 10c connect a fixing head 12 of the plate 4, located in the upper zone of the suspension structure 3, to a cap 13 located in its lower zone. The cap 13 is generally flat and has on its upper face a thicker zone 14 which extends between the sector 10a and the opposite opening 11a. A tongue 15 is made by means of a U-slot in the thicker zone 14. A pin 16 is formed on the lower face of the tongue 15. The width of the thicker zone 14 is equal to the distance between the two tongues 8a, 8b of the base 2. The thickness of the cap 13 outside the thicker zone 14 is equal to the distance between the tongues 8a, 8b of the base 2 of the upper face 2b of this base. To mount the suspension structure 3 on the base 2, the openings 11b, 11c are presented in front of the ends of the tongues 8a and 8b, and the cap 13 is slid under the tabs 8a and 8b. The tongues 8a and 8b are guided by the edges of the thicker zone 14.

Pour faire remonter le téton 16 de la calotte 13 sur la face supérieure 2a de l'embase 2, on exerce sur son extrémité un effort vertical. Lorsque la calotte 13 est totalement engagée sur l'embase 2, le téton 16 redescend et se loge dans le trou 9 de l'embase 2. La structure de suspension 3 est alors immobilisée en traction par les languettes 8a et 8b qui agissent comme des pinces et en rotation autour de l'axe X par le téton 16 qui loge dans le trou 9. Le positionnement du téton 16 est évidemment calculé en fonction de la position du trou 9 par rapport à l'axe X.To raise the pin 16 of the cap 13 on the upper face 2a of the base 2, is exerted on its end a vertical force. When the cap 13 is fully engaged on the base 2, the pin 16 descends and is housed in the hole 9 of the base 2. The suspension structure 3 is then immobilized in tension by the tongues 8a and 8b which act as clamps and rotated about the axis X by the pin 16 which lodges in the hole 9. The positioning of the stud 16 is obviously calculated as a function of the position of the hole 9 relative to the axis X.

La tête 12 de la structure de suspension 3 se présente sous la forme d'un col comportant un orifice traversant 17 dans l'axe X. Cette tête 12 est destinée à loger dans un orifice central 18 ménagé dans le plateau 4. La paroi périphérique de la tête 12 est globalement cylindrique et se termine à l'extrémité supérieure de la structure de suspension 3 par deux bourrelets radialement opposés 19a et 19b. Une nervure axiale 20 est formée sur la paroi périphérique de la tête 12 sous chaque bourrelet 19a et 19b. La tête 12 est raccordée aux secteurs 10a, 10b, 10c par un épaulement annulaire 21 servant de support au plateau 4.The head 12 of the suspension structure 3 is in the form of a neck having a through-orifice 17 in the X-axis. This head 12 is intended to be housed in a central orifice 18 formed in the plate 4. The peripheral wall of the head 12 is generally cylindrical and ends at the upper end of the suspension structure 3 by two radially opposite beads 19a and 19b. An axial rib 20 is formed on the peripheral wall of the head 12 under each bead 19a and 19b. The head 12 is connected to the sectors 10a, 10b, 10c by an annular shoulder 21 serving as a support for the plate 4.

Le plateau 4, montré en détail sur les figures 7 et 8, a une forme globalement rectangulaire ou carrée. Il peut également avoir tout autre forme géométrique. L'essentiel est que les formes des plateaux équipant un sommier par exemple, soient complémentaires et associés. Le plateau 4 peut être réalisé en toute sorte de matériau, notamment en thermoplastique, en bois, ou dans un multicomposant. Il peut être recouvert de tissu par souci d'esthétique. Il comporte de préférence une pluralité de fentes ou d'ouvertures permettant l'aération de l'élément de rembourrage qu'il supporte. Son orifice central 18 est adapté selon les dimensions de la tête de fixation 12 et des bourrelets 19a et 19b. L'orifice central 18 comporte des protubérances 22 diamétralement opposées qui coulissent entre les extrémités des bourrelets 19a et 19b lors du montage du plateau 4 sur la tête de fixation 12. Chaque protubérance 22 présente une rainure 23 destinée à coopérer avec une nervure 20, après rotation d'un quart de tour du plateau 4 autour de l'axe X. Les protubérances 22 sont dimensionnées axialement et circonférentiellement de telle manière qu'après le pivotement d'un quart de tour autour de l'axe X les protubérances 22 se logent sous les bourrelets 19a et 19b, les rainures 23 coopérant avec les nervures 20. Ce dispositif de fixation, dit à baïonnette, est en soi connu et ne mérite pas d'autres explications. Le plateau 4 après montage est immobilisé axialement et en rotation par rapport à la structure de suspension 3.The tray 4, shown in detail in Figures 7 and 8, has a generally rectangular or square shape. It can also have any other geometric shape. The bottom line is that the forms of trays equipping a bed frame for example, are complementary and associated. The plate 4 can be made of any kind of material, especially thermoplastic, wood, or a multicomponent. It can be covered with fabric for aesthetic reasons. It preferably comprises a plurality of slots or openings for aeration of the upholstery element that it supports. Its central orifice 18 is adapted according to the dimensions of the attachment head 12 and the beads 19a and 19b. The central orifice 18 has diametrically opposed protuberances 22 which slide between the ends of the beads 19a and 19b during assembly of the plate 4 on the fixing head 12. Each protrusion 22 has a groove 23 intended to cooperate with a rib 20, after rotation of a quarter turn of the plate 4 about the axis X. The protuberances 22 are dimensioned axially and circumferentially so that after the pivoting of a quarter turn around the axis X the protuberances 22 are housed under the beads 19a and 19b, the grooves 23 cooperating with the ribs 20. This fixing device, said bayonet, is in itself known and does not deserve other explanations. The plateau 4 after mounting is immobilized axially and in rotation with respect to the suspension structure 3.

Les figures 9 et 10 montrent en détail un organe raidisseur 5 monobloc réalisé par moulage en un matériau semblable à celui utilisé pour réaliser la structure de suspension 3. Cet organe raidisseur 5 est introduit dans l'axe X de la structure de suspension 3 par l'orifice 17 de la tête de fixation 12 du plateau 4. Il comporte notamment à son extrémité supérieure un bouchon 24 qui obture l'orifice 17. Ce bouchon 24 comporte des moyens pour permettre sa fixation dans l'orifice 17 par rotation de l'organe raidisseur 5, par exemple, par rapport à la structure de suspension 3, lors du montage. L'organe raidisseur 5 est interposé entre la calotte 13 et la tête de fixation 12 du plateau 4. L'organe raidisseur 5 assure un durcissement de la suspension dans les zones de sommier où les charges recensées sont les plus importantes. Lorsque l'organe raidisseur 5 n'est pas nécessaire, l'orifice 17 de la tête de fixation 13 est obturé par un capuchon 90 montré sur la figure 33.FIGS. 9 and 10 show in detail a monobloc stiffening member 5 produced by molding in a material similar to that used to produce the suspension structure 3. This stiffening member 5 is introduced into the X axis of the suspension structure 3 by the orifice 17 of the attachment head 12 of the plate 4. It comprises in particular at its upper end a plug 24 which closes the orifice 17. This plug 24 comprises means for its attachment in the orifice 17 by rotation of the stiffening member 5, for example, with respect to the suspension structure 3, during assembly. The stiffening member 5 is interposed between the cap 13 and the attachment head 12 of the plate 4. The stiffening member 5 ensures a hardening of the suspension in the box spring areas where the listed loads are the largest. When the stiffening member 5 is not necessary, the orifice 17 of the fixing head 13 is closed by a cap 90 shown in FIG.

Les figures 11 à 13 montrent une première variante du dispositif de suspension décrit ci-dessus. La calotte 13 de la structure de suspension 3 a une épaisseur homogène et présente en regard de l'ouverture latérale 11a une rainure 30 qui sert de guidage à une paroi médiane reliant une languette 31 formée sur la face supérieure 2b de l'embase 2 à cette embase 2. L'embase 2 comporte en outre sur sa face inférieure 2a un tenon 32 de fixation rapide sur une traverse et deux crochets latéraux 33a, 33b qui viennent agripper les bords de la traverse, et sur sa face supérieure 2b un dispositif de clippage 34 en regard de l'extrémité libre de la languette 31, qui immobilise la structure de suspension 3 par rapport à l'embase 2 après son montage. La tête de fixation 12 du plateau 4 est pleine et comporte à sa périphérie une pluralité de logements 35 dans lesquels viennent loger par clippage des doigts élastiques formés dans l'orifice central du plateau 4, tels que ceux décrits dans la demande de brevet FR 98 00187 de la demanderesse, et visibles sur le plateau 4 représenté sur la figure 31.Figures 11 to 13 show a first variant of the suspension device described above. The cap 13 of the suspension structure 3 has a uniform thickness and has opposite the lateral opening 11a a groove 30 which serves to guide a median wall connecting a tongue 31 formed on the upper face 2b of the base 2 to this base 2. The base 2 further comprises on its lower face 2a a quick fastening pin 32 on a cross member and two lateral hooks 33a, 33b which grip the edges of the cross member, and on its upper face 2b a device for clipping 34 facing the free end of the tongue 31, which immobilizes the suspension structure 3 relative to the base 2 after mounting. The fixing head 12 of the plate 4 is solid and comprises at its periphery a plurality of housings 35 in which are housed by clipping elastic fingers formed in the central hole of the plate 4, such as those described in the patent application FR 98 00187 of the applicant, and visible on the plate 4 shown in Figure 31.

Les figures 14 à 16 montrent une deuxième variante de réalisation de l'invention. L'embase 2 comporte un orifice central 6 pour l'introduction d'une vis de fixation sur une traverse et un téton 7 qui émerge sur sa face inférieure 2a pour son immobilisation en rotation sur la traverse. L'embase 2 peut également avoir, sur sa face inférieure 2a, plusieurs tétons 7 alignés ou une nervure de manière à permettre un accostage en aveugle dans une rainure ménagée dans la traverse pour une plus juste et rapide mise en place de l'embase 2 sur la plateforme déterminant la surface d'appui. La structure de suspension 3 est fixée sur l'embase 2 au moyen d'un dispositif à baïonnette. A cet effet, l'embase 2 présente sur sa face supérieure 2b trois crochets curvilignes 40a, 40b, 40c dirigés vers l'axe de l'embase 2, et la calotte 13 présente trois crochets 41a, 41b, 41c dirigés radialement vers l'extérieur et qui coopèrent par rotation autour de l'axe X confondu avec l'axe de l'embase 2 avec les crochets 40a, 40b, 40c. Des nervures 42 formées au-dessus des crochets 41a, 41b, 41c viennent coopérer avec des rainures 43 formées respectivement sur les crochets 40a, 40b, 40c pour immobiliser en rotation la structure de suspension 3 par rapport à l'embase 2 après montage. Comme on le voit sur les figures 14 à 16, la tête de fixation 12 du plateau 4 est semblable à celle montrée sur les figures 11 et 12, mais elle pourrait être semblable à celle montrée sur les figures 2 et 6.Figures 14 to 16 show a second embodiment of the invention. The base 2 comprises a central orifice 6 for the introduction of a fixing screw on a crossbar and a pin 7 which emerges on its lower face 2a for its immobilization in rotation on the crosses. The base 2 may also have, on its lower face 2a, several lugs 7 aligned or a rib so as to allow a blind docking in a groove in the cross member for a fair and quick introduction of the base 2 on the platform determining the support surface. The suspension structure 3 is fixed on the base 2 by means of a bayonet device. For this purpose, the base 2 has on its upper face 2b three curvilinear hooks 40a, 40b, 40c directed towards the axis of the base 2, and the cap 13 has three hooks 41a, 41b, 41c directed radially towards the outside and cooperating by rotation about the X axis coincides with the axis of the base 2 with the hooks 40a, 40b, 40c. Ribs 42 formed above the hooks 41a, 41b, 41c cooperate with grooves 43 formed respectively on the hooks 40a, 40b, 40c to immobilize in rotation the suspension structure 3 relative to the base 2 after mounting. As seen in Figures 14 to 16, the attachment head 12 of the tray 4 is similar to that shown in Figures 11 and 12, but could be similar to that shown in Figures 2 and 6.

Les figures 17 et 18 montrent une troisième variante de réalisation de l'invention. L'embase 2 présente sur sa face supérieure deux crochets 44a, 44b opposés dirigés radialement vers l'extérieur qui viennent agripper les parois les plus rapprochées d'une ouverture 45 rectangulaire ménagée au centre de la calotte 13 de la structure de suspension 3 et dimensionnée pour permettre le passage des crochets 44a et 44b. L'embase 2 présente en outre sur la face supérieure deux tétons 46a, 46b qui coulissent sur des rampes circulaires ménagées dans la face inférieure de la calotte 13 et viennent loger dans des trous ménagés dans la face inférieure de la calotte 13 afin de verrouiller la structure de suspension 3 sur l'embase 2 après son montage par rotation d'un quart de tour.Figures 17 and 18 show a third embodiment of the invention. The base 2 has on its upper face two opposite hooks 44a, 44b directed radially outwardly which grip the walls closest to a rectangular opening 45 formed in the center of the cap 13 of the suspension structure 3 and dimensioned to allow the passage of the hooks 44a and 44b.

Les figures 34 à 38 montrent une huitième variante du dispositif de suspension décrit en référence aux figures 1 à 10. L'embase 2 diffère de celle montrée sur les figures 3 et 4 par le fait qu'elle comporte sur son pourtour un embrèvement 100 qui s'étend entre les extrémités libres des languettes latérales 8a et 8b. Elle comporte également sur sa face inférieure 2a, le long de l'embrèvement 100, un bourrelet 101 situé au-dessus de la surface d'appui de la traverse. La face supérieure 2b de l'embase 2 est exempte du trou 9 montré sur la figure 4. Cette face supérieure 2b présente en regard des languettes latérales 8a et 8b des surépaisseurs 102a et 102b.FIGS. 34 to 38 show an eighth variant of the suspension device described with reference to FIGS. 1 to 10. The base 2 differs from that shown in FIGS. 3 and 4 in that it comprises on its periphery a recess 100 which extends between the free ends of the lateral tongues 8a and 8b. It also has on its underside 2a, along the recess 100, a bead 101 located above the bearing surface of the crosspiece. The upper face 2b of the base 2 is free of the hole 9 shown in FIG. 4. This upper face 2b has, next to the lateral tongues 8a and 8b, extra thicknesses 102a and 102b.

La structure de suspension 3, adaptée à cette embase 2 et montrée en détail sur les figures 37 et 38, comporte, comme la structure de suspension 3, montrée sur les figures 5 et 6, une zone plus épaisse 14 sur la face supérieure de la calotte 13 qui après montage de la structure de suspension 3 sur l'embase 2 est disposée entre les languettes latérales 8a et 8b, et sur la face inférieure de la calotte 13 des nervures parallèles 103a et 103b qui après montage de la structure de suspension 3 sur l'embase 2 sont disposées entre les surépaisseurs 102a et 102b de la face supérieure 2b de l'embase. Les nervures 103a et 103b sont disposées sous la zone plus épaisse 14 et sont parallèles aux bords latéraux de cette zone plus épaisse 14. La structure de suspension 3 présente en outre sous la face inférieure de la calotte 13, et au droit de l'ouverture latérale 11a un crochet 104 qui s'engage dans l'embrèvement 100 et dont l'extrémité coopère avec le bourrelet 101 pour verrouiller la structure de suspension 3 sur l'embase 2. Cette structure de suspension 3 est semblable à celle montrée sur les figures 5 et 6, en ce qui concerne les secteurs 10a, 10b, 10c, les ouvertures latérales 11a, 11b, 11c et la tête 12 de fixation d'un plateau 4.The suspension structure 3, adapted to this base 2 and shown in detail in FIGS. 37 and 38, comprises, like the suspension structure 3, shown in FIGS. 5 and 6, a thicker zone 14 on the upper face of the cap 13 which after mounting of the suspension structure 3 on the base 2 is disposed between the lateral tongues 8a and 8b, and on the underside of the cap 13 of the parallel ribs 103a and 103b which after mounting the suspension structure 3 on the base 2 are arranged between the extra thicknesses 102a and 102b of the upper face 2b of the base. The ribs 103a and 103b are disposed under the thicker zone 14 and are parallel to the lateral edges of this thicker zone 14. The suspension structure 3 furthermore has under the lower face of the cap 13, and to the right of the opening lateral 11a a hook 104 which engages in the recess 100 and whose end cooperates with the bead 101 to lock the suspension structure 3 on the base 2. This suspension structure 3 is similar to that shown in the figures 5 and 6, with regard to the sectors 10a, 10b, 10c, the lateral openings 11a, 11b, 11c and the head 12 for fixing a plate 4.

Les figures 39 et 40 montrent un support 110 d'une extrémité de traverse de sommier, montrée en pointillés, sur laquelle sont montés des dispositifs de suspension 1, tels que ceux décrits ci-dessus, disposés côte à côte. Ce support 110 comporte une paroi verticale 111 destinée à être plaquée contre la face interne d'un long pan et fixée sur ce long pan par des vis traversant des orifices 112a et 112b ménagés dans la paroi 111, ou par des tenons formés sur cette paroi verticale 111, ou par une cornière d'accrochage reposant sur la face supérieure du long pan. Un berceau 113 s'étend à l'horizontale à partir de la région inférieure de la paroi verticale 111. Ce berceau 113 présente deux zones d'extrémité 114a et 114b recourbées vers le haut. La zone médiane du berceau 113 supporte une languette élastique 115 sur laquelle repose une extrémité de traverse. A l'extrémité de chaque zone recourbée 114a et 114b sont prévus deux éléments élastiques, à savoir un retour latéral 116 qui vient en appui contre un flanc de la traverse, et un élément élastique 117 en forme de U renversé dont l'extrémité libre 118 vient en appui sur la face supérieure de la traverse.Figures 39 and 40 show a support 110 of a bedstead crosspiece end, shown in dashed lines, on which are mounted suspension devices 1, such as those described above, arranged side by side. This support 110 comprises a vertical wall 111 intended to be pressed against the inner face of a long panel and fixed on this long panel by screws passing through orifices 112a and 112b formed in the wall 111, or by tenons formed on this wall. vertical 111, or by an attachment angle resting on the upper face of the long pan. A cradle 113 extends horizontally from the lower region of the vertical wall 111. This cradle 113 has two end zones 114a and 114b curved upwards. The middle zone of the cradle 113 supports an elastic tongue 115 on which a cross-bar end rests. At the end of each curved zone 114a and 114b are provided two elastic elements, namely a lateral return 116 which abuts against a sidewall of the crossmember, and an inverted U-shaped elastic element 117 whose free end 118 bears on the upper face of the crossbar.

L'extrémité de la traverse est introduit par le dessus dans l'espace délimité par la languette élastique 115 et les extrémités des retours latéraux 116 et des éléments élastiques 117.The end of the crossbar is introduced from above into the space delimited by the elastic tongue 115 and the ends of the lateral returns 116 and the elastic elements 117.

Les retours latéraux 116 viennent pincer les flancs de la traverse, en assurant les variabilités des cotes d'usinage. Les éléments élastiques 117 permettent le calage en hauteur des traverses, tandis que la languette élastique 115 compense les écarts d'épaisseur des traverses et permet en outre d'amortir un ensemble de dispositifs de suspension 1 fixés sur la traverse.Lateral returns 116 pinch the flanks of the cross, ensuring the variability of the machining dimensions. The elastic elements 117 allow the height adjustment of the sleepers, while the resilient tongue 115 compensates for the differences in thickness of the sleepers and furthermore makes it possible to damp a set of suspension devices 1 fixed on the crosspiece.

Dans les différents modes de réalisation de l'invention décrits ci-dessus, le plateau 4 a une forme quadrangulaire et est symétrique par rapport à des plans longitudinaux et transversaux passant par l'axe X. Il est évident que les plateaux 4 équipant les dispositifs de suspension 1 situés sur les bords d'un sommier peuvent être équipés de plateaux 4 légèrement différents. Dans tous les cas, les systèmes de fixation du plateau 4 sur la tête 12 de la structure de suspension 3 permettront une immobilisation du plateau 4 par rapport à la structure 3 en traction selon l'axe X et en rotation autour de l'axe X. Il en est de même des systèmes de fixation de la structure de suspension 3 sur l'embase 2 et de cette dernière sur une traverse de la plate-forme d'appui.In the different embodiments of the invention described above, the plate 4 has a quadrangular shape and is symmetrical with respect to longitudinal and transverse planes passing through the axis X. It is obvious that the trays 4 equipping the devices suspension 1 located on the edges of a bed frame can be equipped with trays 4 slightly different. In all cases, the fixing systems of the plate 4 on the head 12 of the suspension structure 3 will immobilize the plate 4 relative to the structure 3 in traction along the X axis and in rotation around the X axis It is the same for fixing systems of the suspension structure 3 on the base 2 and the latter on a cross member of the support platform.
