Description

La présente invention concerne un dispositif de suspension destiné à s'étendre entre les longerons d'un cadre de sommier ou de lit en vue de supporter un matelas, ainsi qu'un sommier équipé d'un tel dispositif de suspension.The present invention relates to a suspension device for extending between the longitudinal members of a bed frame or bed to support a mattress, and a bed base equipped with such a suspension device.

Depuis de nombreuses années, sont apparus sur le marché, des sommiers dits sommiers à lattes, dans lesquels les éléments de suspension sont constitués de lattes, généralement en bois ou en fibre de verre, chaque latte étant fixée à chacune de ses extrémités, aux longerons du cadre de sommier ou de lit, par l'intermédiaire de pièces de liaison, généralement en matière de synthèse appelées rotules. Cet ensemble lattes/rotules, forme ainsi un système de suspension dans lequel la fonction ressort est assurée par deux types de matériau, à savoir d'une part, le matériau constitutif de la latte, d'autre part, le matériau constitutif de la rotule. Du fait du maintien de la latte uniquement à ses extrémités par lesdites rotules, il est nécessaire de cintrer la latte pour éviter un affaissement de la partie centrale de cette dernière lorsqu'elle est sollicitée notamment à l'état couché d'une personne sur le matelas supporté par lesdites lattes. Par ailleurs, de telles lattes cintrées, sont préfabriquées cintrées avec un rayon constant, de sorte que, selon la longueur finale de la latte, le rayon de courbure de cintrage peut être plus ou moins accentué. Dans le cas d'un rayon de courbure important, on observe un phénomène de roulis, qui se traduit en particulier pour la personne dormant couchée sur le côté, par l'impression de tomber du lit, le cintrage de la latte et l'affaissement des extrémités de la latte sous l'effet du poids de la personne, amplifiant ce phénomène.For many years, slatted bases have appeared on the market, in which the suspension elements consist of slats, generally of wood or fiberglass, each slat being fixed at each of its ends, to the longitudinal members. the bed frame frame or bed, through connecting parts, generally synthetic material called ball joints. This slats / spherical assembly thus forms a suspension system in which the spring function is ensured by two types of material, namely on the one hand, the constituent material of the slat, on the other hand, the material constituting the patella . Due to the maintenance of the batten only at its ends by said patella, it is necessary to bend the batten to prevent sagging of the central portion of the latter when it is requested especially in the lying state of a person on the mattress supported by said slats. Furthermore, such curved slats are prefabricated curved with a constant radius, so that, depending on the final length of the lath, the bending radius of curvature can be more or less accentuated. In the case of a large radius of curvature, there is a phenomenon of rolling, which is reflected in particular for the sleeping person lying on its side, the impression of falling off the bed, the bending of the lath and sagging ends of the lath under the effect of the weight of the person, amplifying this phenomenon.

Pour éviter un tel phénomène de roulis, des dispositifs de suspension délimitant une surface de couchage sensiblement rectiligne ont été développés, comme l'illustre en particulier le brevet EP 1 516 568 . Le dispositif de suspension décrit dans ce brevet, comprend au moins un corps allongé de type latte ou lame, délimitant une surface d'appui du matelas, au moins une traverse rigide, support dudit corps et, interposé entre traverse et corps d'appui du matelas, au moins un élément élastiquement déformable. L'avantage d'un tel dispositif est qu'il assure un amortissement homogène du fait de la nature continue de la surface d'appui du matelas, par opposition à de nombreux dispositifs de suspension de l'état de la technique, dans lesquels la surface d'appui du matelas est formée d'éléments ponctuels tels que des coupelles, répartis sur toute la largeur de la surface de couchage et venant supporter ponctuellement le matelas. Il en résulte un amortissement hétérogène de l'ensemble et une complexité dans la fabrication. Dans le brevet EP 1 516 568 , la réalisation en une seule pièce de l'élément élastiquement déformable et du corps servant à la délimitation de la surface d'appui du matelas rend la construction d'un tel ensemble, complexe et onéreuse. En outre, si le réglage des éléments élastiquement déformables est choisi "mou", par opposition à un réglage "dur" ou "ferme", il existe à nouveau, un risque d'affaissement des extrémités de la surface de couchage délimitée par ledit corps, et par suite, la réapparition du phénomène de roulis. Si le réglage des éléments est choisi dur, le dispositif de suspension peut apparaître comme inconfortable aux yeux de l'utilisateur.To avoid such a roll phenomenon, suspension devices delimiting a substantially rectilinear coating surface have been developed, as illustrated in particular by the patent. EP 1,516,568 . The suspension device described in this patent comprises at least one elongate body of batten or slat type, delimiting a support surface of the mattress, at least one crossbar rigid support of said body and, interposed between the cross member and the support body of the mattress, at least one elastically deformable element. The advantage of such a device is that it ensures a homogeneous damping due to the continuous nature of the support surface of the mattress, as opposed to many suspension devices of the state of the art, in which the The support surface of the mattress is formed of point elements such as cups, distributed over the entire width of the sleeping surface and punctually support the mattress. This results in a heterogeneous damping of the whole and a complexity in the manufacture. In the patent EP 1,516,568 the one-piece construction of the elastically deformable element and the body serving to delimit the bearing surface of the mattress makes the construction of such a complex and expensive assembly. In addition, if the adjustment of the elastically deformable elements is chosen "soft", as opposed to a setting "hard" or "firm", there is again a risk of collapse of the ends of the sleeping surface delimited by said body and, consequently, the reappearance of the roll phenomenon. If the adjustment of the elements is chosen hard, the suspension device may appear uncomfortable to the eyes of the user.

Les inconvénients décrits ci-dessus s'appliquent également à la suspension décrite dans le brevet FR-2.832.041 où la surface d'appui du matelas, la traverse support de ladite surface et les éléments élastiquement déformables sont moulés d'une seule pièce. La conception retenue entraîne nécessairement la réalisation d'éléments élastiquement déformables différents d'un élément à un autre avec la nécessité de compenser les différences de hauteur entre surface d'appui et traverse au niveau desdits éléments. A nouveau, lorsqu'un réglage dur ou mou est choisi, il s'applique à l'ensemble des éléments élastiquement déformables.The disadvantages described above also apply to the suspension described in the patent FR-2832041 wherein the support surface of the mattress, the support beam of said surface and the elastically deformable elements are molded in one piece. The selected design necessarily involves the production of elastically deformable elements different from one element to another with the need to compensate for differences in height between the bearing surface and crosses at the level of said elements. Again, when a hard or soft setting is chosen, it applies to all of the elastically deformable elements.

Un but de la présente invention est donc de proposer un dispositif de suspension du type précité, dont la conception permet de supprimer le phénomène de roulis, sans nuire au confort de l'utilisateur.An object of the present invention is therefore to provide a suspension device of the aforementioned type, the design of which eliminates the roll phenomenon, without harming the comfort of the user.

Un autre but de la présente invention est de proposer un dispositif de suspension dont la conception permet de moduler aisément les caractéristiques de ladite suspension en termes de dureté, sans compliquer la fabrication du dispositif.Another object of the present invention is to provide a suspension device whose design allows to easily modulate the characteristics of said suspension in terms of hardness, without complicating the manufacture of the device.

A cet effet, l'invention a pour objet un dispositif de suspension selon la revendication 1.For this purpose, the subject of the invention is a suspension device according to claim 1.

La réalisation des deux éléments élastiquement déformables dits d'extrémité, supportant les extrémités du corps allongé, elles-mêmes supportant les rives longitudinales du matelas, sous forme d'éléments de dureté supérieure, permet, du fait d'une telle rigidification des extrémités du corps allongé d'appui du matelas, d'empêcher un affaissement desdites extrémités, et par suite, l'apparition du phénomène de roulis observé dans l'état de la technique.The realization of the two so-called end elastically deformable elements, supporting the ends of the elongate body, themselves supporting the longitudinal banks of the mattress, in the form of elements of higher hardness, makes it possible, because of such a stiffening of the ends of the elongated support body of the mattress, to prevent a collapse of said ends, and consequently, the appearance of the roll phenomenon observed in the state of the art.

L'invention a encore pour objet un sommier du type constitué d'un cadre dont les longerons sont reliés entre eux par des dispositifs de suspension pour former une surface d'appui d'un matelas, caractérisé en ce que chaque dispositif de suspension est du type précité.The subject of the invention is also a bed base of the type consisting of a frame whose longitudinal members are interconnected by suspension devices to form a bearing surface of a mattress, characterized in that each suspension device is aforementioned type.

L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence aux dessins annexés dans lesquels :

  • la figure 1 représente une vue de face d'un dispositif de suspension conforme à l'invention ;
  • la figure 2 représente une vue en perspective du dispositif de la figure 1, les moyens de fixation du dispositif aux longerons ayant été représentés à l'état non assemblé et ;
  • la figure 3 représente une vue en perspective du corps allongé positionné à l'envers et des éléments élastiquement déformables équipant un tel corps, l'un des éléments élastiquement déformables ayant été représenté en position non assemblée ;
The invention will be better understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which:
  • the figure 1 represents a front view of a suspension device according to the invention;
  • the figure 2 represents a perspective view of the device of the figure 1 , the fastening means of the device to the longitudinal members having been shown in the unassembled state and;
  • the figure 3 is a perspective view of the elongate body positioned upside down and elastically deformable elements equipping such a body, one of the elastically deformable elements having been shown in the unassembled position;

Comme mentionné ci-dessus, le dispositif 1 de suspension, objet de l'invention, est plus particulièrement destiné à s'étendre entre les longerons (non représentés) d'un cadre de sommier ou de lit en vue de supporter un matelas. Généralement un cadre de sommier ou de lit présente une pluralité de dispositifs 1 de suspension du type précité, s'étendant parallèlement les uns par rapport aux autres et couvrant ainsi la totalité de la surface du cadre de sommier ou de lit à équiper.As mentioned above, the suspension device 1, object of the invention, is more particularly intended to extend between the longitudinal members (not shown) of a bed frame or bed to support a mattress. Generally a bed frame or bed has a plurality of suspension devices 1 of the aforementioned type, extending parallel to each other and thus covering the entire surface of the bed frame or bed to be equipped.

Le dispositif 1 de suspension, objet de l'invention, comprend au moins un corps 2 allongé de type latte(s) ou lame(s), délimitant une surface 10 d'appui du matelas. Dans les exemples représentés, le corps 2 allongé d'appui du matelas est formé d'une lame ou latte unique délimitant entre ses extrémités, à bords relevés ou non, une surface d'appui de matelas de type plateau sensiblement rectiligne et non courbe comme les lattes ou lames cintrées de l'état de la technique. De manière équivalente, ce corps 2 allongé d'appui du matelas, aurait pu être constitué d'un ensemble de lames ou lattes, reliées l'une à l'autre par des moyens de liaison appropriés, pour délimiter, à nouveau, à l'état non sollicité du dispositif, une surface d'appui du matelas, du type plateau de type sensiblement rectiligne.The suspension device 1, which is the subject of the invention, comprises at least one elongate body 2 of latte (s) or blade (s) type, delimiting a support surface 10 of the mattress. In the examples shown, the elongated support body 2 of the mattress is formed of a single blade or slat delimiting between its ends, with or without raised edges, a substantially flat and non-curved plateau-type mattress support surface. curved slats or blades of the state of the art. Equivalently, this elongate support body 2 of the mattress, could have been constituted by a set of blades or slats, connected to each other by appropriate connecting means, to demarcate, again, the unsolicited state of the device, a bearing surface of the mattress, tray type of substantially straight type.

Le dispositif 1 de suspension comprend encore, une traverse 3 rigide, support dudit corps 2 et interposé entre traverse 3 et corps 2 d'appui du matelas, au moins un élément 4 élastiquement déformable. La ou chaque traverse 3 s'étend entre les longerons du cadre de sommier ou de lit, le corps 2 s'étendant au-dessus et sensiblement parallèlement à la ou aux traverses 3.The suspension device 1 further comprises a rigid cross member 3 supporting said body 2 and interposed between the cross member 3 and the support body 2 of the mattress, at least one elastically deformable element 4. The or each crosspiece 3 extends between the longitudinal members of the bed frame or bed, the body 2 extending above and substantially parallel to the cross or 3.

De manière caractéristique à l'invention, le dispositif 1 comprend une pluralité d'éléments 4, 4A élastiquement déformables répartis sur toute la longueur du corps 2 et supportant de place en place ledit corps 2. Cette disposition permet ainsi d'éviter un affaissement du corps 2 dans sa zone centrale ou médiane. Au moins deux, représentés en 4A aux figures, des éléments 4, 4A de la pluralité d'éléments élastiquement déformables, sont disposés l'un à, ou au voisinage d'une, extrémité du corps 2 d'appui du matelas, l'autre à, ou au voisinage de, l'autre extrémité du corps 2 d'appui du matelas, et sont de dureté supérieure à au moins une partie des autres éléments élastiquement déformables pour rigidifier le corps 2 d'appui du matelas à ses extrémités.Characteristically to the invention, the device 1 comprises a plurality of elements 4, 4A elastically deformable distributed over the entire length of the body 2 and supporting place in place said body 2. This arrangement thus prevents a collapse of the body 2 in its central or median area. At least two, represented at 4A in the figures, elements 4, 4A of the plurality of elastically deformable elements, are arranged one to, or in the vicinity of, an end of the support body 2 of the mattress, the other at or near the other end of the support body 2 of the mattress, and are of greater hardness than at least a portion of the other elastically deformable elements to stiffen the support body 2 of the mattress at its ends.

Dans les exemples représentés, le corps 2 allongé s'étendant entre lesdits longerons du cadre de sommier ou de lit est réalisé sous forme d'une pièce indépendante des éléments 4, 4A des éléments élastiquement déformable. Ce corps 2 allongé délimite ainsi une surface d'appui essentiellement rectiligne de type plateau entre les longerons du cadre de sommier ou de lit, les extrémités dudit corps étant destinées à supporter les rives longitudinales du matelas. Comme ce corps 2 est rigidifié à chacune de ses extrémités par l'intermédiaire des éléments 4A élastiquement déformables, tout phénomène de roulis est empêché. Les éléments 4A élastiquement déformables appartenant à la famille des éléments de dureté supérieure, sont réalisés identiques en forme et en dimension mais en un matériau de dureté différente du matériau constitutif des éléments élastiquement déformables appartenant à au moins une autre famille d'éléments. Ainsi, à titre d'exemple, chaque élément 4A élastiquement déformable de dureté supérieure peut être réalisé en un matériau présentant une dureté comprise entre 60 et 70 Shores D, choisi dans le groupe des matériaux formés par des élastomères .Les éléments 4 élastiquement déformables disposés entre les éléments 4A élastiquement déformables d'extrémité de dureté supérieure, peuvent quant à eux, être réalisés en un matériau choisi dans le groupe formé par des élastomères et présenter une dureté comprise entre 50 et 60 Shores D. Dans ce cas, les éléments élastiquement déformables représentent deux familles d'éléments. Bien évidemment, ce nombre de familles d'éléments peut être supérieur à deux. De même, la famille d'éléments de dureté supérieure peut comporter plus de deux éléments, ces éléments supplémentaires étant de préférence disposés au voisinage des éléments 4A d'extrémité.In the examples shown, the elongated body 2 extending between said longitudinal members of the bed frame or bed is formed as a separate part of the elements 4, 4A of the elastically deformable elements. This elongated body 2 thus delimits an essentially straight platen-like bearing surface between the longitudinal members of the bed frame or bed frame, the ends of said body being intended to support the longitudinal banks of the mattress. As this body 2 is stiffened at each of its ends via the elements 4A elastically deformable, any roll phenomenon is prevented. The elements 4A elastically deformable belonging to the family of elements of higher hardness, are made identical in shape and size but in a material of different hardness of the material constituting the elastically deformable elements belonging to at least one other family of elements. Thus, for example, each elastically deformable element 4A of greater hardness can be made of a material having a hardness of between 60 and 70 Shores D, selected from the group of materials formed by elastomers. The elements 4 elastically deformable arranged between the elastically deformable elements 4A end of higher hardness, can in turn, be made of a material selected from the group formed by elastomers and have a hardness of between 50 and 60 Shores D. In this case, the elements elastically deformable represent two families of elements. Of course, this number of families of elements can be greater than two. Likewise, the family of elements of higher hardness can comprise more than two elements, these additional elements being preferably arranged in the vicinity of the end elements 4A.

De préférence chaque élément 4, 4A élastiquement déformable est relié de manière amovible à la, ou aux traverse(s) 3 et/ou au corps 2 d'appui du matelas. Il en résulte la possibilité de faire varier à volonté la nature des éléments 4, 4A élastiquement déformables sans compliquer la fabrication de l'ensemble.Preferably each elastically deformable element 4, 4A is removably connected to the cross member (s) 3 and / or to the support body 2 of the mattress. This results in the possibility of varying at will the nature of the elements 4, 4A elastically deformable without complicating the manufacture of the assembly.

Dans les exemples représentés, chaque élément 4, 4A élastiquement déformable est relié au corps 2 d'appui du matelas par un montage à emboîtement, verrouillé par rotation. Chaque élément 4, 4A élastiquement déformable est monté à emboîtement, coulissant sur la ou les traverse(s) 3.In the examples shown, each elastically deformable element 4, 4A is connected to the support body 2 of the mattress by an interlocking fitting, locked by rotation. Each elastically deformable element 4, 4A is mounted interlockingly, sliding on the cross member (s) 3.

Comme l'illustrent les figures, le dispositif 1 de suspension comporte ici au moins deux traverses 3 parallèles, reliées l'une à l'autre par la pluralité d'éléments 4, 4A élastiquement déformables et équipées à/ou au voisinage de chacune de leurs extrémités de moyens rigides 9 de fixation aux longerons du cadre de sommier. Ces moyens 9 de fixation sont réalisés à l'aide d'une pièce formant palier, s'insérant par l'intermédiaire de plots dans des perçages ménagés dans lesdits longerons. Une solution présentant un dispositif de suspension à une seule traverse aurait pu également être envisagée de manière équivalente.As illustrated in the figures, the suspension device 1 here comprises at least two parallel crosspieces 3, connected to one another by the plurality of elements 4, 4A that are elastically deformable and equipped at or in the vicinity of each of them. their ends rigid means 9 for attachment to the longitudinal members of the bed frame. These fastening means 9 are made using a bearing part, inserting via studs into holes in said longitudinal members. A solution having a single-cross suspension device could also be considered in an equivalent manner.

Dans l'exemple représenté aux figures, au moins un de préférence chaque élément 4, 4A élastiquement déformable affecte la forme d'un corps 2 tubulaire muni à sa base d'au moins un organe 7 de liaison à la ou une traverse 3 et à son sommet, d'au moins un organe 6 de liaison au corps 2 d'appui du matelas. L'organe 7 de liaison d'un élément 4, 4A élastiquement déformable à la/ou une traverse 3 affecte la forme d'un anneau accolé, par sa surface périphérique externe, au pourtour périphérique du corps 5 de l'élément 4, 4A élastiquement déformable, la traverse 3 étant enfilée dans ledit anneau. Dans le cas d'un dispositif de suspension équipé de deux traverses 3, l'élément 4, 4A élastiquement déformable comporte deux anneaux comme l'illustrent les figures, lesdits anneaux étant accolés chacun par leur surface périphérique externe au pourtour périphérique dudit corps 5 de l'élément 4, 4A élastiquement déformable.In the example shown in the figures, at least one preferably each elastically deformable element 4, 4A has the shape of a tubular body 2 provided at its base with at least one connecting member 7 to the cross member 3 and its top, at least one connecting member 6 to the support body 2 of the mattress. The member 7 connecting an element 4, 4A elastically deformable to the / or a cross member 3 has the shape of a ring joined by its outer peripheral surface to the peripheral periphery of the body 5 of the element 4, 4A elastically deformable, the cross member 3 being threaded into said ring. In the case of a suspension device equipped with two crosspieces 3, the element 4, 4A elastically deformable comprises two rings as illustrated in the figures, said rings being contiguous each by their outer peripheral surface to the periphery of said body 5 of the element 4, 4A elastically deformable.

L'organe 6 de liaison de l'élément 4, 4A élastiquement déformable au corps 2 d'appui du matelas, est formé par une ouverture dans ledit élément 4, 4A. Cette ouverture coopère avec un téton 8 faisant saillie de la face du dessous du corps 2 d'appui du matelas. Dans les exemples représentés, la tête du téton 8 affecte la forme d'un T venant se loger dans une ouverture oblongue de l'élément 4, 4A élastiquement déformable, cette ouverture oblongue s'élargissant dans sa partie médiane pour permettre le passage du corps du téton et former une surface de guidage lors de l'entraînement relatif en rotation du téton et de l'ouverture autour de l'axe longitudinal du téton, en vue d'obtenir un montage à emboîtement verrouillé de l'élément élastiquement déformable et du corps 2 d'appui du matelas. Grâce à ce montage amovible entre éléments 4, 4A élastiquement déformables et corps 2 d'appui du matelas, il est aisé de réaliser un dispositif 1 de suspension de construction modulaire où la dureté de chaque élément élastiquement déformable est choisie en fonction de la zone du corps de l'utilisateur à recevoir et des souhaits de l'utilisateur.The member 6 connecting the element 4, 4A elastically deformable to the support body 2 of the mattress, is formed by an opening in said element 4, 4A. This opening cooperates with a stud 8 protruding from the underside of the support body 2 of the mattress. In the examples shown, the head of the stud 8 has the shape of a T which is housed in an oblong opening of the element 4, 4A which is elastically deformable, this oblong opening widening in its median part to allow the passage of the body of the pin and forming a guide surface during the relative drive in rotation of the pin and the opening around the longitudinal axis of the pin, in order to obtain a latched fitting of the elastically deformable element and the 2 support body of the mattress. Thanks to this removable assembly between elements 4, 4A that are elastically deformable and the support body 2 of the mattress, it is easy to produce a device 1 for suspension of modular construction where the hardness of each elastically deformable element is chosen as a function of the area of the the user's body to receive and the wishes of the user.

L'assemblage des éléments constitutifs d'un tel dispositif 1 de suspension s'opère comme suit :

  • Dans un premier temps, et comme l'illustre la figure 3, le corps 2 allongé délimitant la surface 10 d'appui du matelas est positionné avec sa face 10 d'appui du matelas contre le sol pour permettre la fixation sur sa face du dessous des éléments 4, 4A élastiquement déformables. Une fois les éléments 4, 4A élastiquement déformables fixés audit corps 2 allongé, en prenant soin d'équiper ledit corps 2 d'éléments 4A élastiquement déformables de dureté supérieure au niveau des extrémités, il est alors possible d'enfiler à l'intérieur des anneaux formant un alignement d'anneaux, de chacun des éléments élastiquement déformables, une traverse 3. Le dispositif 1 de suspension est alors retourné pour permettre le logement des traverses 3 dans les paliers, formés par les moyens 9 de fixation desdites traverses aux longerons du cadre de sommier. Le montage est alors achevé.
The constituent elements of such a suspension device 1 are assembled as follows:
  • At first, and as illustrated by the figure 3 , the elongated body 2 delimiting the support surface 10 of the mattress is positioned with its support surface 10 of the mattress against the ground to allow attachment on its underside of the elements 4, 4A elastically deformable. Once the elements 4, 4A are elastically deformable fixed to said elongate body 2, taking care to equip said body 2 with elastically deformable elements 4A of greater hardness at the ends, it is then possible to thread inside the rings forming an alignment of rings, each of the elastically deformable elements, a 3. The suspension device 1 is then turned over to allow the sleepers 3 to be housed in the bearings, formed by the means 9 for fixing said sleepers to the longitudinal members of the bed frame. The assembly is then completed.
