Description

La présente invention concerne les éléments de suspension pour sommier ou siège du type à lattes ou multi-éléments, munis de moyens de réglage de fermeté.The present invention relates to the slatted or multi-element type slatted frame or seat suspension elements provided with firmness adjustment means.

Les sommiers à lattes ou du type multi-éléments utilisent couramment des éléments de suspension. Dans certains cas, des aménagements particuliers sont prévus pour faire varier l'élasticité ou la fermeté de ces éléments de suspension. Par exemple dans le document FR-2 793 125 les éléments de suspension se présentent sous la forme d'une structure monobloc munie de lames déformables formant ressorts. Les aménagements particuliers réalisés au niveau de ces lames ressorts permettent, avec l'aide de pièces rapportées et interchangeables, de modifier leur élasticité par l'adjonction d'éléments ressorts complémentaires.Slatted frames or multi-element type commonly use suspension elements. In some cases, special arrangements are provided to vary the elasticity or firmness of these suspension elements. For example in the document FR-2 793 125 the suspension elements are in the form of a one-piece structure provided with deformable spring blades. The particular arrangements made with these leaf springs make it possible, with the aid of inserts and interchangeable parts, to modify their elasticity by the addition of complementary spring elements.

On connaît également, par les documents EP-0 512 569 ou encore DE-296 11 876 , des organes de suspension constitués d'une liaison élastique interposée entre une tête supérieure réceptionnant une latte et une embase inférieure, ladite liaison élastique étant formée de bras articulés s'étendant dans le sens de l'axe longitudinal de la tête supérieure. Un système de curseur est agencé pour se déplacer sur la longueur d'un ou de plusieurs des bras articulés, de manière à modifier les capacités de déformation de la liaison élastique. Cependant, les moyens correspondants de réglage de fermeté, du type à curseur, sont relativement complexes, ils sont d'un encombrement important et nécessitent un déplacement conséquent pour obtenir une différence sensible en terme de fermeté.It is also known from the documents EP-0 512 569 or DE-296 11 876 suspension members consisting of an elastic connection interposed between an upper head receiving a slat and a lower base, said elastic connection being formed of articulated arms extending in the direction of the longitudinal axis of the upper head. A slider system is arranged to move along the length of one or more of the articulated arms, so as to modify the deformation capabilities of the elastic link. However, the corresponding firmness adjustment means, of the slider type, are relatively complex, they are of a large size and require substantial displacement to obtain a significant difference in terms of firmness.

Le document FR-2 839 870 de la demanderesse présente un élément de suspension pour un sommier (ou un siège) du type à lattes ou multi-éléments qui est constitué d'une embase inférieure, d'une tête supérieure et d'un système intermédiaire de liaison élastique.
L'embase inférieure est munie de moyens de fixation sur le châssis du sommier (ou du siège), ou sur un élément solidaire de ce châssis.
La tête supérieure est aménagée pour accueillir et fixer une ou plusieurs lattes, ou un plateau ; elle comporte un axe longitudinal adapté pour s'étendre dans le sens de la largeur dudit sommier ou siège.
D'autre part, la liaison intermédiaire élastique est aménagée entre ladite embase et ladite tête pour permettre un déplacement vertical de cette dernière vers l'embase, selon au moins une composante perpendiculaire à cette embase. Cette liaison élastique comprend, d'une part, deux bras rigides en Vé dont l'une des extrémités est solidaire, soit de la tête, soit de l'embase, par l'intermédiaire de moyens d'articulation, et d'autre part, une partie formant ressort qui s'étend entre l'autre extrémité desdits bras et ladite tête ou ladite embase, selon le cas. Cet élément de suspension comporte encore des moyens pour régler et contrôler l'amplitude du mouvement angulaire dudit ou desdits bras par rapport à ladite tête ou embase lors du déplacement vertical précité de ladite tête, de façon à permettre de modifier à volonté ses caractéristiques de fermeté.The document FR-2,839,870 of the Applicant presents a suspension element for a bed base (or seat) of the slatted or multi-element type which consists of a lower base, an upper head and an intermediate system of elastic connection.
The lower base is provided with fixing means on the frame of the bed base (or seat), or on a member integral with this frame.
The upper head is arranged to accommodate and fix one or more slats, or a tray; it comprises a longitudinal axis adapted to extend in the width direction of said bed or seat.
On the other hand, the elastic intermediate connection is arranged between said base and said head to allow a vertical displacement of the latter to the base, according to at least one component perpendicular to this base. This elastic connection comprises, on the one hand, two rigid arms V e whose one end is secured to either the head or the base, by means of hinge means, and on the other hand, a spring portion extending between the other end of said arms and said head or said base, as the case may be. This suspension element further comprises means for adjusting and controlling the amplitude of the angular movement of said arm or said arm relative to said head or base during said vertical displacement of said head, so as to allow to modify at will its firmness characteristics. .

Dans l'élément de suspension correspondant, les deux bras en Vé (et les parties formant ressort associées) sont orientés perpendiculairement à l'axe longitudinal de la tête (et donc dans le sens des longerons latéraux de la structure de sommier ou de siège), ce qui peut autoriser des possibilités d'oscillations trop importantes des lattes ou du plateau supporté du fait de la présence des moyens de réglage de fermeté (et des moyens d'articulation tête/bras).In the corresponding suspension element, the two V-arms (and the associated spring portions) are oriented perpendicularly to the longitudinal axis of the head (and thus in the direction of the side rails of the bed frame or seat structure) , which may allow possibilities of excessive oscillations of the slats or the supported plate because of the presence of the firmness adjustment means (and the head / arm articulation means).

La présente invention propose de remédier à ces différents inconvénients.The present invention proposes to remedy these various disadvantages.

Ainsi, cet élément de suspension pour sommier ou siège du type à lattes ou multi-éléments est du type constitué :

  • d'une embase munie de moyens de fixation sur le châssis dudit sommier ou siège, ou sur un élément solidaire dudit châssis,
  • d'une tête qui est aménagée pour accueillir et fixer une ou plusieurs lattes, ou un plateau, laquelle tête comporte un axe longitudinal adapté pour s'étendre dans le sens de la largeur dudit sommier ou siège,
  • d'une liaison élastique entre ladite embase et ladite tête, aménagée pour permettre un déplacement vertical de cette dernière vers l'embase, selon au moins une composante perpendiculaire à ladite embase, laquelle liaison élastique comprend, d'une part, au moins un bras rigide dont l'une des extrémités est solidaire soit de ladite embase, soit de ladite tête, par l'intermédiaire de moyens d'articulation et, d'autre part, une partie formant ressort qui s'étend entre l'autre extrémité dudit bras et ladite tête ou ladite embase, selon le cas, et - des moyens pour permettre un réglage de ses caractéristiques de fermeté.
    Conformément à la présente invention, le ou les bras de la liaison élastique s'étendent dans le sens de l'axe longitudinal de la tête, l'articulation de ce ou de ces bras s'étend perpendiculairement à l'axe longitudinal de la tête, et ledit ou lesdits bras rigides comportent au moins un mentonnet destiné à coopérer avec une pièce en forme de came dont la position est réglable par une manoeuvre en rotation ou en translation, ceci de manière à régler et contrôler à volonté l'amplitude du mouvement angulaire dudit ou desdits bras par rapport à ladite tête ou ladite embase, autour dudit axe d'articulation, lors du déplacement vertical de ladite tête.
Thus, this slatted or multi-element type slatted or slatted suspension element is of the type consisting of:
  • a base provided with fastening means on the frame of said bed frame or seat, or on a member secured to said frame,
  • a head which is arranged to accommodate and fix one or more slats, or a plate, which head has a longitudinal axis adapted to extend in the width direction of said bed or seat,
  • an elastic connection between said base and said head, arranged to allow a vertical displacement of the latter towards the base, according to at least one component perpendicular to said base, which elastic connection comprises, on the one hand, at least one arm rigid one of whose ends is secured to said base or said head, by means of hinge means and, on the other hand, a spring portion which extends between the other end of said arm and said head or said base, as the case may be, and means for enabling adjustment of its firmness characteristics.
    According to the present invention, the arm or the arm of the elastic connection extend in the direction of the longitudinal axis of the head, the articulation of this or these arms extends perpendicularly to the longitudinal axis of the head , and said one or more rigid arms comprise at least one lug intended to cooperate with a cam-shaped part whose position is adjustable by a maneuver in rotation or in translation, so as to adjust and control at will the amplitude of the movement angular said arm or said arm relative to said head or said base, about said hinge axis, during the vertical displacement of said head.

Dans une forme de réalisation particulière, l'embase est munie de moyens de fixation sur l'un des longerons longitudinal de la structure de sommier (ou de siège), et la tête est munie d'au moins un logement pour la réception d'une latte, le ou les bras de la liaison élastique s'étendant dans le sens de l'axe desdits logements de réception de latte(s), correspondant au sens de l'axe longitudinal de ladite tête.In a particular embodiment, the base is provided with fixing means on one of the longitudinal longitudinal members of the bed frame structure (or seat), and the head is provided with at least one housing for the reception of a batten, the arm or arms of the elastic connection extending in the direction of the axis of said batten receiving housing (s), corresponding to the direction of the longitudinal axis of said head.

Dans ce cadre, l'élément de suspension peut comporter un bras unique centré sur le plan longitudinal médian de la tête, lequel bras se prolonge par un élément ressort en forme de lame plate.In this context, the suspension element may comprise a single arm centered on the median longitudinal plane of the head, which arm is extended by a spring element shaped flat blade.

Dans une forme de réalisation préférée, le ou les bras de l'élément de suspension s'étendent depuis la tête vers le bas, en direction de l'intérieur du sommier, c'est-à-dire entre ses deux longerons longitudinaux.In a preferred embodiment, the arm or arms of the suspension element extend from the head down towards the interior of the bed, that is to say between its two longitudinal longitudinal members.

Les parties constitutives de cet élément de suspension, à savoir l'embase, la tête et la liaison élastique entre les deux, se présente avantageusement sous une forme monobloc réalisée en matériau thermoplastique de type élastomère.The constituent parts of this suspension element, namely the base, the head and the elastic connection between the two, is advantageously in a one-piece form made of thermoplastic material of elastomer type.

L'invention sera encore illustrée, sans être aucunement limitée, par la description suivante d'une forme de réalisation particulière, donnée uniquement à titre d'exemple et représentée sur les dessins annexés dans lesquels :

  • la figure 1 est une vue de côté d'un élément de suspension conforme à l'invention, représenté sous forme de schéma fonctionnel,
  • la figure 2 est une vue de face de l'élément de suspension illustré figure 1, toujours sous forme de schéma fonctionnel.
The invention will be further illustrated, without being limited in any way, by the following description of a particular embodiment, given solely by way of example and shown in the accompanying drawings in which:
  • FIG. 1 is a side view of a suspension element according to the invention, represented in the form of a block diagram,
  • Figure 2 is a front view of the suspension element shown in Figure 1, still in block diagram form.

Tel que représenté sur les figures 1 et 2, l'élément de suspension 1 se présente sous la forme d'une rotule équipant la structure d'un sommier comprenant un cadre formé de longerons longitudinaux 2 et de traverses d'extrémité 3.
Ici, l'élément de suspension 1 comprend :

  • une embase 4 aménagée pour être fixée sur l'un des longerons longitudinaux 2 (en particulier sur la face interne de celui-ci),
  • une tête 5 aménagée pour accueillir une ou plusieurs lattes 6 (en particulier ici deux lattes 6 par l'intermédiaire de logements 6') ; cette tête 5 comporte un axe longitudinal 7 orienté perpendiculairement aux longerons 2 supports et parallèlement aux traverses d'extrémité 3, ainsi qu'un plan médian 7' séparant les deux logements de lattes 6', et
  • une liaison élastique 8 reliant la tête 5 et l'embase 4. Cette liaison élastique 8 permet à la tête 5 de se déplacer par rapport à l'embase 4 selon au moins une composante perpendiculaire à cette dernière.
As shown in Figures 1 and 2, the suspension element 1 is in the form of a ball joint equipping the structure of a bed base comprising a frame formed of longitudinal longitudinal members 2 and end cross members 3.
Here, the suspension element 1 comprises:
  • a base 4 arranged to be fixed on one of the longitudinal longitudinal members 2 (in particular on the inner face thereof),
  • a head 5 arranged to accommodate one or more slats 6 (in particular here two slats 6 via housing 6 '); this head 5 has a longitudinal axis 7 oriented perpendicularly to the support beams 2 and parallel to the end crosspieces 3, and a median plane 7 'separating the two slats housing 6', and
  • an elastic connection 8 connecting the head 5 and the base 4. This elastic connection 8 allows the head 5 to move relative to the base 4 according to at least one component perpendicular to the latter.

En outre, un système 9 de réglage de fermeté est interposé entre la tête 5 et la liaison élastique 8.In addition, a firmness control system 9 is interposed between the head 5 and the elastic connection 8.

La liaison élastique 8 est constituée d'un élément ressort 10 interposé entre l'embase 4 et un bras 11 solidaire de la tête 5. Le bras 11 s'étend dans le sens de l'axe 7 de la tête 5 (et aussi dans le sens de l'axe des logements de lattes 6') et il constitue un levier de déformation de l'élément ressort 10.
Ce bras 11 est articulé en 12 au niveau de sa zone de solidarisation avec la tête 5.The elastic connection 8 consists of a spring element 10 interposed between the base 4 and an arm 11 integral with the head 5. The arm 11 extends in the direction of the axis 7 of the head 5 (and also in the direction of the axis of the slats housing 6 ') and it constitutes a deformation lever of the spring element 10.
This arm 11 is articulated at 12 at its zone of attachment to the head 5.

L'élément ressort 10 prolonge le bras 11 et il s'étend lui aussi dans le sens de l'axe 7 de la tête 5 ; il se présente sous la forme d'une lame flexible en forme générale de C, par exemple en portion d'ellipse.The spring element 10 extends the arm 11 and it also extends in the direction of the axis 7 of the head 5; it is in the form of a flexible blade in the general shape of C, for example in ellipse portion.

Le bras 11 se présente avantageusement sous la forme d'un plat de quelques centimètres de largeur et de longueur, et de quelques millimètres d'épaisseur.
L'élément ressort 10 se présente avantageusement sous la forme d'une lame plate de quelques centimètres de largeur et de longueur, et de 1 à 2 mm d'épaisseur.The arm 11 is advantageously in the form of a flat of a few centimeters in width and length, and a few millimeters thick.
The spring element 10 is advantageously in the form of a flat blade of a few centimeters in width and length, and 1 to 2 mm thick.

De préférence, la tête 5, l'embase 4 et la liaison élastique 8 sont réalisés monoblocs par moulage de matière thermoplastique type élastomère, les zones d'articulation 10, 12 étant obtenues par des amincissements de matière. En particulier, l'articulation 12 est en forme d'amincissement allongé qui s'étend sur une ligne perpendiculaire à l'axe longitudinal 7 de la tête 5.Preferably, the head 5, the base 4 and the elastic connection 8 are made in one piece by molding thermoplastic material elastomeric type, the hinge areas 10, 12 being obtained by material thinning. In particular, the hinge 12 is in the form of an elongated thinning which extends on a line perpendicular to the longitudinal axis 7 of the head 5.

Le mouvement de la tête 5 (lié à un appui sur les lattes 6 notamment) s'accompagne d'un mouvement du bras 11 et en particulier d'un pivotement de ce bras 11 autour de son articulation 12, et en même temps, on observe une déformation de l'élément ressort 10.The movement of the head 5 (linked to a support on the slats 6 in particular) is accompanied by a movement of the arm 11 and in particular a pivoting of the arm 11 around its hinge 12, and at the same time, observe a deformation of the spring element 10.

L'amplitude du mouvement du bras 11 par rapport à la tête 5 est réglée et contrôlée au moyen du système de réglage de fermeté 9. Ce système de réglage de fermeté 9 comprend des moyens constitués d'au moins une pièce en forme de came 13, rapportée et interposée entre le bras 11 et la tête 5, et en particulier entre un ou plusieurs mentonnets 14 solidaire(s) du bras 11 et une surface d'appui 15 faisant office de butée, située sous la tête 5.The amplitude of the movement of the arm 11 relative to the head 5 is adjusted and controlled by means of the firmness control system 9. This firmness control system 9 comprises means consisting of at least one cam-shaped piece 13 , reported and interposed between the arm 11 and the head 5, and in particular between one or more lugs 14 integral with the arm 11 and a bearing surface 15 acting as a stop, situated under the head 5.

En fonction de sa forme, le déplacement de la came 13 permet de modifier à volonté la capacité de mouvement du bras 11 et en particulier l'amplitude de son mouvement angulaire autour de son axe d'articulation 12.
Ce contrôle du mouvement du bras 11 influe sur la capacité de déformation des moyens élastiques 10 et permet de contrôler la fermeté de la rotule. Ainsi, le réglage de la fermeté de l'élément de suspension 1 est réalisé par un simple déplacement de la came 13, ceci à volonté, directement lors de la confection du sommier, ou bien par l'utilisateur lui-même.Depending on its shape, the displacement of the cam 13 makes it possible to modify at will the movement capacity of the arm 11 and in particular the amplitude of its angular movement around its hinge axis 12.
This control of the movement of the arm 11 influences the deformation capacity of the elastic means 10 and makes it possible to control the firmness of the ball joint. Thus, the adjustment of the firmness of the suspension element 1 is achieved by a simple displacement of the cam 13, this at will, directly during the making of the bed base, or by the user himself.

Tout type de came 13 peut être mis en oeuvre, fonctionnant par rotation ou par translation, en particulier comme détaillé dans le document FR-2 839 870 . Les surfaces d'appui de la came 13, le nombre et la position des mentonnets 14 seront adaptés en conséquence.Any type of cam 13 can be implemented, operating by rotation or by translation, in particular as detailed in the document FR-2,839,870 . The bearing surfaces of the cam 13, the number and the position of the chins 14 will be adapted accordingly.

Le positionnement du bras plan 11 (et de l'élément élastique 10 associé) dans le sens de l'axe 7 de la tête 5 permet en particulier de limiter les possibilités d'oscillations latérales de la ou des lattes 6, en particulier du fait de l'orientation de l'articulation 12 (cette orientation étant perpendiculaire à l'axe 7 de la tête 5).
Ce positionnement autorise également une course de suspension importante.The positioning of the plane arm 11 (and of the associated elastic element 10) in the direction of the axis 7 of the head 5 makes it possible in particular to limit the possibilities of lateral oscillations of the slat or slats 6, in particular because of the orientation of the hinge 12 (this orientation being perpendicular to the axis 7 of the head 5).
This positioning also allows a significant suspension stroke.

Dans le mode de réalisation illustré, l'embase 4 et la tête 5 sont reliées par une liaison élastique 8 (bras 11 prolongé par un élément élastique 10), qui se situe sur l'axe médian 7' de l'élément de suspension. Dans des variantes de réalisation, la tête 5 et l'embase 4 pourront être reliées par plusieurs bras parallèles orientés dans le même sens (associés chacun à un élément ressort).In the illustrated embodiment, the base 4 and the head 5 are connected by an elastic connection 8 (arm 11 extended by an elastic element 10), which is located on the central axis 7 'of the suspension element. In alternative embodiments, the head 5 and the base 4 may be connected by several parallel arms oriented in the same direction (each associated with a spring element).

Egalement, dans le mode de réalisation illustré, le bras 11 s'étend depuis la tête 5 vers l'intérieur du sommier (entre les deux longerons longitudinaux 2), la forme en C de l'élément élastique 10 étant ouverte vers l'extérieur du cadre. Dans des variantes de réalisation, l'orientation du bras (ou des bras) et de l'élément ressort associé pourra être inversée, le bras s'étendant alors vers le bas et en direction de l'extérieur du sommier, et l'élément ressort en C étant ouvert en direction de l'intérieur du sommier.Also, in the illustrated embodiment, the arm 11 extends from the head 5 towards the inside of the bed base (between the two longitudinal longitudinal members 2), the C shape of the elastic element 10 being open towards the outside of the frame. In alternative embodiments, the orientation of the arm (or arms) and the associated spring element can be reversed, the arm then extending downwards and towards the outside of the bed base, and the element C spring being open towards the interior of the bed.

Bien entendu, comme prévu dans le document FR-2 839 870 précité, le même principe de suspension peut être mis en oeuvre :

  • pour réaliser non plus un sommier mais un siège, et/ou
  • pour former un élément de suspension recevant non plus une ou plusieurs lattes, mais un plateau, de manière à obtenir un sommier (ou un siège) de type multi-éléments.
Of course, as provided in the document FR-2,839,870 mentioned above, the same principle of suspension can be implemented:
  • to realize either a bed base but a seat, and / or
  • to form a suspension element receiving not one or more slats, but a tray, so as to obtain a bed base (or a seat) of the multi-element type.

De même, ce principe de suspension peut être mis en oeuvre pour former un curseur venant se positionner sur des lattes interposées entre les longerons longitudinaux du sommier.Similarly, this suspension principle can be implemented to form a slider that is positioned on slats interposed between the longitudinal longitudinal members of the bed.

Encore comme prévu dans le document FR-2 839 870 , il est possible d'envisager de positionner la structure de came du côté de l'embase.Still as expected in the document FR-2,839,870 , it is possible to consider positioning the cam structure on the side of the base.
