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 seat, arranged between a bearing surface and a padding.

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 precisely to a unitary suspension device for a multi-element type box spring, this device being intended for be interposed between a platform determining a bearing surface and a padding element such as a mattress, and having a base intended to be fixed on a platform element, a structure of suspension fixed on the base and a plate carried by the structure of suspension and serving as support for the padding element, said suspension structure being of revolution about 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 crosspieces constituting the platform. Usually these elements are symmetrical by with respect to a transverse median plane and with respect to a median plane longitudinal, and the hardness is not homogeneous according to the inclination undergone by the tray.

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 describes 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 radial arms diverge elastic. The ends of these arms include fixing means on a base ring. After mounting these ends of arms on the base ring the arms are in the form of sectors of a sphere, separated by side openings, but they are subject to elastic stresses, and in the event of rupture of these attachments, they must return to 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 most prior art close to the invention has already provided a suspension structure hollowed out spherical shape made of a foam of a synthetic material elastic which has holes at its upper and lower ends for fixing by clipping the base and the plate. After mounting, the suspension structure is normally airtight, and operates at like a balloon. The problem which arises concerns the sealing at level of 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.Starting from this state of the art, the invention proposes a new type of suspension in which he does not ask questions air tightness.

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 only appears at rest in the form of a hollowed-out sphere and monobloc comprising a plurality of sectors separated by side openings and made of a flexible synthetic material or vulcanized rubber with a hardness between 40 shores A and 70 shores D.

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 compression and bending forces, under load, and the interior 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 tray relative to the base and to the platform element, the base comprises means to prevent rotation with respect to the platform member.

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 tray include cooperating means to ensure 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 produced in one piece. They can also be carried out in two separate rooms. In this case, the suspension structure and the base include cooperating means for ensuring 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 connection between the connection structure and the base can be realized in different ways, either by a shaped slide system dovetail and clip system to lock the two parts together after assembly, either by a clipping system and positioning of a tenon in a mortise, either by a system with bayonet combined with a clipping system, either by a device with clamps guided by a slide during assembly, with a device anti-rotation lock which is automatically positioned at the end of the mounting.

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 liaison means are formed on the two parts during the 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 can be spherical and include 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 stiffness desired.

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, this the latter may include in its internal cavity a stiffening member removable disposed in its axis of revolution, said member comprising advantageously at its upper end a plug which accommodates in a through hole formed in a fixing head of the plate 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 mode for carrying out the invention. This suspension device 1 is intended for be fixed on a cross member of a support platform, not shown on the drawings, and essentially comprises 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 structure of suspension 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 a support for a padding element, a mattress for example, not shown in the drawings. The device suspension 1 may further comprise a stiffening member 5 which allows to modify the stiffness of the suspension device 1 according to the position of this last in the box spring. The box spring has a plurality of devices of suspension 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 in a suitable rigid synthetic material, such as polypropylene or polyamide, by molding, or in metal. It has a central opening 6 allowing its fixing by means of a screw on a cross member, and, on its face lower 2a, a stud 7 intended to be housed in a hole made in the crosspiece, in order to prevent the rotation of the base 2 after its fixing on the crosses. The base 2 further comprises, on its upper face 2b, two side tabs 8a and 8b which extend in the same direction parallel to the cross member and a hole 9 disposed above the stud 7. The tabs 8a and 8b serve to retain the suspension structure 3, and the hole 9 serves to immobilize the suspension structure 3, in particular by rotation after assembly of the latter, 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 around a vertical axis X. It is produced in a flexible synthetic material such as TPE or vulcanized rubber. The hardnesses of the materials are adjusted to the loads to be supported. The hardness are preferably between 40 shores A and 70 shores D. The suspension structure 3 is in the form of a sphere which has three sectors 10a, 10b, 10c, separated by three openings lateral 11a, 11b, 11c, regularly spaced around the X axis. The circumferential extent of sectors 10a, 10b, 10c and the openings lateral 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 a thicker area on its upper face 14 which extends between sector 10a and the opposite opening 11a. A tongue 15 is produced by means of a U-shaped slot in the area more thick 14. A stud 16 is formed on the underside of the tongue 15. The width of the thicker zone 14 is equal to the distance between the two tabs 8a, 8b of the base 2. The thickness of the cap 13 to the outside of the thicker zone 14 is equal to the distance separating the tabs 8a, 8b of the base 2 of the upper face 2b of this base. To mount the suspension structure 3 on the base 2, we has the openings 11b, 11c 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 stud 16 of the cap 13 on the face upper 2a of the base 2, a force is exerted on its end vertical. When the cap 13 is fully engaged on the base 2, the pin 16 descends and is housed in hole 9 of base 2. Structure suspension 3 is then immobilized in traction by the tongues 8a and 8b which act as clamps and rotate around the X axis through the stud 16 which lodges in hole 9. The positioning of stud 16 is obviously calculated as a function of the position of 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 present under the form of a neck having a through hole 17 in the X axis. 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 with 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 a annular shoulder 21 serving to support 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 plate 4, shown in detail in Figures 7 and 8, has a shape generally rectangular or square. It can also have any other geometric shape. The main thing is that the shapes of the trays fitted a box spring for example, are complementary and associated. The tray 4 can be made of any kind of material, in particular thermoplastic, wooden, or in a multi-component. He can be covered with fabric for aesthetic reasons. It preferably includes a plurality of slots or openings allowing ventilation of the element of padding it supports. Its central orifice 18 is adapted according to the dimensions of the fixing head 12 and of the beads 19a and 19b. The hole central 18 has diametrically opposite 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 a quarter turn of the plate 4 around the X axis. The protrusions 22 are dimensioned axially and circumferentially in such a way that after the pivoting of a quarter turn around the X axis the protrusions 22 are housed under the beads 19a and 19b, the grooves 23 cooperating with the ribs 20. This fixing device, known as a bayonet, is in itself known and does not deserve further explanation. Plateau 4 after assembly is immobilized axially and in rotation relative to the structure suspension 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.Figures 9 and 10 show in detail a stiffening member 5 monobloc produced by molding in a material similar to that used to make the suspension structure 3. This stiffening member 5 is introduced into the X axis of the suspension structure 3 through the orifice 17 of the fixing head 12 of the plate 4. It notably has at its end upper a plug 24 which closes the orifice 17. This plug 24 comprises means to allow its fixing in the orifice 17 by rotation of the stiffening member 5, for example, with respect to the structure of suspension 3, during assembly. The stiffening member 5 is interposed between the cap 13 and the fixing head 12 of the plate 4. The stiffening member 5 ensures hardening of the suspension in the box spring areas where the charges identified are the most important. When the organ stiffener 5 is not necessary, the orifice 17 of the fixing head 13 is closed by a cap 90 shown in FIG. 33.

    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 device of suspension described above. The cap 13 of the structure of suspension 3 has a uniform thickness and is present opposite the opening 11a has a groove 30 which serves as a guide for a central 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 underside 2a a tenon 32 for quick attachment to a crossmember and two hooks lateral 33a, 33b which grip the edges of the crosspiece, and on its upper face 2b a clipping device 34 facing the end free of the tongue 31, which immobilizes the suspension structure 3 by compared to base 2 after mounting. The fixing head 12 of the tray 4 is full and has a plurality of housings at its periphery 35 in which reside by clipping elastic fingers formed in the central orifice of the plate 4, such as those described in the patent application FR 98 00187 from the applicant, and visible on the plate 4 shown in FIG. 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 alternative embodiment of the invention. The base 2 has a central opening 6 for the introduction of a fixing screw on a cross member and a stud 7 which emerges on its underside 2a for its immobilization in rotation on the crosses. The base 2 can also have, on its lower face 2a, several nipples 7 aligned or a rib so as to allow a blind docking in a groove in the cross member for a fairer and faster installation of the base 2 on the platform determining the support surface. The suspension structure 3 is fixed to 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 outwards and which cooperate by rotation around 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 assembly. As seen in Figures 14 to 16, the fixing head 12 of the plate 4 is similar to that shown in Figures 11 and 12, but it 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 alternative embodiment of the invention. The base 2 has on its upper face two opposite hooks 44a, 44b directed radially outwards which grip the walls closest to an opening 45 rectangular formed in the center of the cap 13 of the structure suspension 3 and dimensioned to allow the passage of hooks 44a and 44b. The base 2 also has two upper surfaces nipples 46a, 46b which slide on circular ramps formed in the underside of the cap 13 and are housed in holes formed in the underside of the cap 13 in order to lock the suspension structure 3 on the base 2 after mounting by rotation a quarter turn.

    Selon une quatrième variante de réalisation de l'invention montrée sur les figures 19 à 21, les moyens de liaison de la structure de suspension 3 et de l'embase 2 comportent une glissière en forme de queue d'aronde. A cet effet, la calotte 13 de la structure de suspension 3 présente sur sa face inférieure une nervure 50 ayant une section en queue d'aronde qui s'étend depuis l'axe X jusqu'au bord de la calotte 13, et qui est susceptible d'être introduite par coulissement dans une nervure 51 ayant également une section en queue d'aronde ménagée dans la face supérieure 2b de l'embase 2. L'embase 2 présente en outre sur sa face inférieure 2a deux parois parallèles 52a, 52b entre lesquelles vient s'insérer une traverse et un téton central 53 qui vient loger dans un trou ménagé dans la traverse.According to a fourth embodiment of the invention shown in Figures 19 to 21, the connecting means of the structure suspension 3 and base 2 have a slide in the form of dovetail. To this end, the cap 13 of the suspension structure 3 has on its underside a rib 50 having a cross section dovetail extending from the X axis to the edge of the cap 13, and which can be slid into a rib 51 also having a dovetail section formed in the upper face 2b of the base 2. The base 2 also has on its lower face 2a two parallel walls 52a, 52b between which is inserted a cross member and a central stud 53 which is housed in a hole in the cross member.

    Les figures 22 et 23 montrent une cinquième variante de réalisation de l'invention. La calotte 13 de la structure de suspension 3 comporte un trou central 54 dans lequel vient se clipper une demi-boule 55 formée sur la face supérieure 2b de l'embase 2. Un tenon 56 est formé sur la face inférieure de la calotte 13. Ce tenon 56 loge dans une mortaise 57 ménagée dans la face supérieure 2b de l'embase 2, et immobile en rotation la structure de suspension 3 par rapport à l'embase 2. L'embase 2 comporte en outre des parois latérales 52a et 52b et un téton 53, comme pour la quatrième variante de réalisation, pour son montage et son immobilisation en rotation sur une traverse.Figures 22 and 23 show a fifth alternative embodiment of the invention. The cap 13 of the suspension structure 3 comprises a central hole 54 in which is clipped a half-ball 55 formed on the upper face 2b of the base 2. A tenon 56 is formed on the face lower of the cap 13. This tenon 56 fits in a mortise 57 formed in the upper face 2b of the base 2, and stationary in rotation of the suspension structure 3 relative to the base 2. The base 2 further comprises side walls 52a and 52b and a stud 53, as for the fourth variant, for its assembly and its immobilization rotating on a cross member.

    Selon une sixième variante de réalisation de l'invention, montrée sur les figures 24 et 25, l'embase 2 présente sur sa face supérieure 2b un orifice central 6 pour sa fixation sur une traverse par une vis. Cet orifice central et entouré d'une structure rectangulaire 60 qui loge dans une ouverture rectangulaire 61 ménagée au centre de la calotte 13. La structure rectangulaire 60 est équipée de languettes élastiques 62a et 62b qui viennent agripper les rebords de l'ouverture rectangulaire 61 ainsi que cela est visible sur la figure 24.According to a sixth alternative embodiment of the invention, shown in FIGS. 24 and 25, the base 2 has on its upper face 2b a central hole 6 for fixing to a crosspiece by a screw. This orifice central and surrounded by a rectangular structure 60 which is housed in a rectangular opening 61 formed in the center of the cap 13. The rectangular structure 60 is equipped with elastic tongues 62a and 62b which grip the edges of the rectangular opening 61 as well as this is visible in figure 24.

    Les figures 26 et 27 montrent une septième variante de réalisation de l'invention. La calotte 13 présente sur sa face inférieure une boule centrale 63 que l'on peut faire coulisser dans une gorge 64 radiale ménagée dans la face supérieure 2b de l'embase 2. D'autres moyens non montrés sur la figure 27 permettent d'immobiliser en rotation la structure de suspension 3 par rapport à l'embase 2 après son montage.Figures 26 and 27 show a seventh alternative embodiment of the invention. The cap 13 has on its underside a ball central 63 which can be slid in a radial groove 64 formed in the upper face 2b of the base 2. Other means not shown in Figure 27 allow to immobilize in rotation the structure suspension 3 relative to the base 2 after mounting.

    Les figures 28 à 31 montrent un deuxième mode de réalisation de l'invention. Ce dispositif de suspension 1 comporte également une embase 2 montrée sur la figure 30, une structure de suspension 3 de forme sphérique montrée sur la figure 29 et un plateau de forme carrée montré sur la figure 31. La structure de suspension 3 présente une tête de fixation 12 du plateau 4, qui présente une paroi cylindrique terminée par un bourrelet annulaire 70, permettant de retenir des doigts élastiques 71 prévus dans la paroi interne de l'orifice central 18 du plateau 4. La paroi interne de cet orifice 18 comporte également des embrèvements 72 qui viennent à cheval sur des nervures radiales opposées 73a et 73b formées dans la partie supérieure de la sphère au pied de la tête 12 afin d'immobiliser, en rotation autour de l'axe X, le plateau 4 par rapport à la structure de suspension 3 après son montage.Figures 28 to 31 show a second embodiment of the invention. This suspension device 1 also includes a base 2 shown in FIG. 30, a suspension structure 3 of spherical shape shown in Figure 29 and a square tray shown in Figure 31. The suspension structure 3 has a head attachment 12 of the plate 4, which has a cylindrical wall terminated by an annular bead 70, making it possible to retain elastic fingers 71 provided in the internal wall of the central orifice 18 of the plate 4. The wall internal of this orifice 18 also includes recesses 72 which straddle opposite radial ribs 73a and 73b formed in the upper part of the sphere at the foot of the head 12 so to immobilize, in rotation around the X axis, the plate 4 relative to the suspension structure 3 after mounting.

    La structure de suspension 3 présente dans son hémisphère inférieur trois secteurs 10a, 10b et 10c séparés par des entailles 11a, 11b, 11c de faible étendue circonférentielle. Mais par rapport au premier mode de réalisation, la structure de suspension 3 ne comporte pas de calotte dans sa zone inférieure. Les extrémités inférieures des secteurs 10a, 10b et 10c sont donc libres. L'embase 2 présente sous sa face inférieure des parois latérales 52a et 52b entre lesquelles se loge une traverse, et un tenon 74 pour sa fixation sur la traverse, et sur sa face supérieure 2b, un col 75 évasé vers le haut et constitué de trois éléments régulièrement espacés autour de l'axe de l'embase 2 et présentant chacun sur leur face extérieure une nervure 76 qui s'étend vers le haut et dont la dimension circonférentielle est égale à la largeur d'une entaille 11a, 11b et 11c. Lorsqu'on étend élastiquement les extrémités inférieures des secteurs 10a, 10b et 10c vers l'extérieur, il est possible de coiffer le col 75 par la partie inférieure de la structure de suspension 3, et de telle manière que les nervures 76 logent dans les entailles 11a, 11b et 11c.The suspension structure 3 present in its hemisphere lower three sectors 10a, 10b and 10c separated by notches 11a, 11b, 11c of small circumferential extent. But compared to the first mode embodiment, the suspension structure 3 does not include a cap in its lower area. The lower ends of sectors 10a, 10b and 10c are therefore free. The base 2 has beneath its underside side walls 52a and 52b between which is housed a cross member, and a tenon 74 for its attachment to the cross member, and on its upper face 2b, a collar 75 flared up and made up of three elements regularly spaced around the axis of base 2 and each having their face exterior a rib 76 which extends upwards and whose dimension circumferential is equal to the width of a notch 11a, 11b and 11c. When elastically extending the lower ends of the sectors 10a, 10b and 10c outwards, it is possible to style the neck 75 by the lower part of the suspension structure 3, and in such a way that the ribs 76 are housed in the notches 11a, 11b and 11c.

    La figure 32 montre un troisième mode de réalisation de l'invention. Ici l'embase 2 et la structure de suspension sont réalisées en une seule pièce. L'embase 2 présente sur sa face inférieure 2a deux tenons 80a et 80b pour sa fixation rapide dans des trous ménagés sur une traverse et éventuellement une butée 81 qui vient en appui contre une face latérale de la traverse.Figure 32 shows a third embodiment of the invention. Here the base 2 and the suspension structure are made in one single piece. The base 2 has two tenons on its underside 2a 80a and 80b for its rapid fixing in holes made on a crosses and possibly a stop 81 which bears against a lateral face of the crosspiece.

    La figure 33 montre un capuchon 90 qui comporte deux pattes 91a et 91b qui peuvent coulisser dans l'espace séparant les bourrelets 19a et 19b de la tête 12 et les protubérances 22 du plateau 4, selon le premier mode de réalisation de l'invention décrit ci-dessus, après pivotement d'un quart de tour du plateau 4 et son encliquetage anti-retour. Ce capuchon 90 peut être en tissu surmoulé ou en une pièce en matière plastique réalisée par thermocompression. Il peut comporter une gravure ou un décor esthétique. Figure 33 shows a cap 90 which has two legs 91a and 91b which can slide in the space separating the beads 19a and 19b of the head 12 and the protrusions 22 of the plate 4, according to the first embodiment of the invention described above, after pivoting of a quarter turn of the plate 4 and its non-return snap. This cap 90 can be in overmolded fabric or in a piece of material plastic produced by thermocompression. It may include an engraving or an aesthetic setting.

    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.Figures 34 to 38 show an eighth variant of the device of suspension described with reference to Figures 1 to 10. The base 2 differs from that shown in FIGS. 3 and 4 by the fact that it includes on its around a recess 100 which extends between the free ends of the side tabs 8a and 8b. It also has on its face lower 2a, along the recess 100, a bead 101 located above of the support surface of the crosspiece. The upper face 2b of the base 2 is free of the hole 9 shown in FIG. 4. This face upper 2b has opposite side tabs 8a and 8b of the 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 Figures 37 and 38, includes, like the structure of suspension 3, shown in FIGS. 5 and 6, a thicker zone 14 on the upper face of the cap 13 which after assembly of the structure suspension 3 on the base 2 is disposed between the side tabs 8a and 8b, and on the underside of the cap 13 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 arranged under the thicker zone 14 and are parallel to the edges side of this thicker area 14. The suspension structure 3 also present under the underside of the cap 13, and to the right of the lateral opening 11 has a hook 104 which engages in the removal 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 Figures 5 and 6, with regard to sectors 10a, 10b, 10c, side 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 at one end of box spring, shown in dotted lines, on which are mounted suspension devices 1, such as those described above, arranged side by side beside. This support 110 has a vertical wall 111 intended to be pressed against the internal face of a long pan and fixed on this long pan by screws passing through orifices 112a and 112b formed in the wall 111, or by studs formed on this vertical wall 111, or by a hanging 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 bent upwards. The middle area of the cradle 113 supports an elastic tongue 115 on which one end of crosses. At the end of each curved zone 114a and 114b are provided with two elastic elements, namely a lateral return 116 which comes resting against a side of the cross member, and an elastic element 117 in inverted U shape whose free end 118 bears on the face top of the crosspiece.

    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 crosspiece is introduced from above into the space delimited by the elastic tongue 115 and the ends of the lateral returns 116 and 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.The lateral returns 116 pinch the sides of the crosspiece, ensuring the variability of the machining dimensions. The elements elastic 117 allow the height adjustment of the sleepers, while the elastic tongue 115 compensates for the differences in thickness of the crosspieces and also allows to cushion 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 various embodiments of the invention described above, the plate 4 has a quadrangular shape and is symmetrical by with respect to longitudinal and transverse planes passing through the X axis. it is obvious that the plates 4 equipping the suspension devices 1 located on the edges of a box spring can be fitted 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 allow a immobilization of the plate 4 relative to the structure 3 in tension according to the X axis and rotating around the X axis. The same is true for systems for fixing the suspension structure 3 to the base 2 and this last on a cross member of the support platform.
