Abstract

The bed base has chest and leg-feet parts which can be raised to variable heights. It is constituted by a flexible assembly (3,4,14) which supports a mattress. The mattress, which extends the length of the bed, rests on the raisable parts (8,15,21,24) which hold the flexible assembly to the desired height with a continuous ergonomic profile. The flexible assembly is formed from two lateral flexible bands (3) between which extend rigid flexible laths engaged in ferrules (4) fixed from place to place on the bands. The bands rest on a rigid plinth (2). The raisable parts are constituted by profiled supports (8,15) whose upper surface is rounded. Pivoting arms (12,18) support under the lower face of these profiled supports and raise them above the plinth so that the flexible bands are applied on and fit their rounded profile.

Description

L'invention se rapporte à un sommier déformable à profil ergonomique dont les plans de couchage sont constitués d'un unique élément support qui est souple dont au moins la tête et le pied sont relevables pour prendre une forme optimale en vue du confort de l'utilisateur.The invention relates to a deformable bed base with an ergonomic profile, the sleeping surfaces of which consist of a single support element which is flexible, at least the head and the foot of which can be raised to take an optimal shape for the comfort of the user.

Les sommiers articulés connus, notamment les sommiers à lattes, comportent un certain nombre de parties indépendantes inclinables qui pivotent par rapport à un cadre fixe et par rapport à leurs parties voisines et qui permettent à la partie couchage de prendre des inclinaisons voulues en fonction de la position de relaxation recherchée. Les parties articulées sont mises en mouvement par un ou des moteurs électriques qui modifient leur orientation par l'intermédiaire de bielles et de leviers pivotants. L'usage le plus courant de ces sommiers consiste à relever la partie buste, c'est-à-dire la tête du sommier pour que l'utilisateur se trouve en position semi-assise lui facilitant par exemple la lecture.Known articulated bed bases, in particular slatted bed bases, have a certain number of independent tilting parts which pivot relative to a fixed frame and relative to their neighboring parts and which allow the sleeping part to take desired inclinations according to the desired relaxation position. The articulated parts are set in motion by one or more electric motors which modify their orientation by means of connecting rods and pivoting levers. The most common use of these bases consists of raising the chest part, that is to say the head of the base so that the user is in a semi-seated position, for example making it easier to read.

Chacune de ces parties indépendantes constitue un élément rigide d'un plan de couchage et quand certaines d'entre elles sont relevées, il subsiste entre les plans voisins des inflexions qui nuisent au confort de la literie malgré la présence du matelas qui les atténue.Each of these independent parts constitutes a rigid element of a sleeping surface and when some of them are raised, there remain between the neighboring planes inflections which harm the comfort of the bedding despite the presence of the mattress which attenuates them.

Il est apparent que la forme optimale que l'on puisse donner à un sommier pour un meilleur confort de l'utilisateur, serait une forme continue, sans lignes brisées, qui épouserait les lignes du corps humain quel que soit le degré de levage de la tête ou du pied de lit.It is apparent that the optimal shape that can be given to a box spring for a better comfort of the user, would be a continuous shape, without broken lines, which will follow the lines of the human body whatever the degree of lifting of the headboard or footboard.

La Demanderesse a trouvé à cela une solution qui consiste à remplacer les parties inclinables indépendantes connues, par un unique élément souple servant de support au matelas qui s'étend sur toute la longueur du sommier, et qui repose lui-même sur des organes de relevage qui sont avantageusement des profilés ergonomiques dont la courbure correspond à la forme optimale recherchée pour la relaxation du corps humain.The Applicant has found a solution to this which consists in replacing the known independent tilting parts, by a single flexible element serving as a support for the mattress which extends over the entire length of the bed base, and which itself rests on lifting members. which are advantageously ergonomic profiles whose curvature corresponds to the optimal shape desired for the relaxation of the human body.

L'invention a donc pour objet un sommier déformable à profil ergonomique dont la partie buste et/ou la partie jambe-pied est relevable à des hauteurs variables par des organes articulés manoeuvrés par au moins un moteur ledit sommier étant constitué d'un ensemble souple servant de support à un matelas, qui s'étend sur toute la longueur du sommier, et qui repose sur des organes de relevage aptes à maintenir l'ensemble souple à la hauteur voulue et avec une courbure continue à profil ergonomique.The invention therefore relates to a deformable bed base with an ergonomic profile, the bust part and / or the leg-foot part can be raised to variable heights by articulated members operated by at least one motor, said bed base being made up of a flexible assembly. serving as a support for a mattress, which extends over the entire length of the bed base, and which rests on lifting members capable of holding the flexible assembly at the desired height and with a continuous curvature with an ergonomic profile.

Selon une caractéristique principale de l'invention, l'ensemble souple est formé de deux bandes latérales flexibles entre lesquelles s'étendent des lattes rigides ou souples, engagées dans des embouts fixés de place en place sur les bandes, et qui reposent sur un socle rigide.According to a main characteristic of the invention, the flexible assembly is formed of two flexible lateral bands between which extend rigid or flexible slats, engaged in end pieces fixed from place to place on the bands, and which rest on a base rigid.

En variante, l'ensemble souple est formé de deux chaînes à maillons rigides articulés entre eux.Alternatively, the flexible assembly is formed of two chains with rigid links hinged together.

Selon une autre variante, l'ensemble souple est formé d'une unique surface souple couvrant toute la largeur du lit, au dessus de laquelle s'étendent des lattes engagées dans des embouts fixés à ladite surface souple.According to another variant, the flexible assembly is formed by a single flexible surface covering the entire width of the bed, above which extend slats engaged in end pieces fixed to said flexible surface.

Plus précisément, les organes de relevage de l'ensemble souple sont constitués de supports profilés dont la face supérieure est arrondie et des bras pivotants en appui sous la face inférieure desdits supports profilés les soulèvent au-dessus du socle rigide pour que les bandes flexibles s'appliquent sur eux et épousent leur profil arrondi.More specifically, the lifting members of the flexible assembly consist of profiled supports whose upper face is rounded and pivoting arms bearing under the lower face of said profiled supports raise them above the rigid base so that the flexible strips 'apply to them and follow their rounded profile.

Avantageusement le support profilé de la partie buste du sommier présente une face supérieure ergonomique de forme arrondie à concavité tournée vers le haut. Il porte aussi deux ergots guidés dans une rampe circulaire à concavité tournée vers le haut disposée à proximité du centre du sommier, sous son socle. On peut aussi utiliser tout autre système capable de créer virtuellement ou réellement un axe d'articulation.Advantageously, the profiled support of the chest part of the bed base has an ergonomic upper face of rounded shape with concavity turned upwards. It also carries two lugs guided in a circular ramp with concavity turned upwards arranged close to the center of the box spring, under its base. One can also use any other system capable of creating a virtual or real articulation axis.

Selon une autre caractéristique de l'invention, le support profilé de la partie jambe-pied du sommier présente une face supérieure ergonomique de forme arrondie dont une première partie est à concavité tournée vers le haut, suivie d'une partie à concavité tournée vers le bas.According to another characteristic of the invention, the profiled support of the leg-foot part of the bed base has an ergonomic upper face of rounded shape, a first part of which is with concavity facing upwards, followed by a part with concavity facing downwards.

En variante de réalisation, les organes de relevage de l'ensemble souple du côté jambe-pied du sommier sont constitués d'au moins deux leviers pivotants en appui sous la bande souple, leviers dont les extrémités coudées au niveau de leurs pivots sont reliées entre elles par une bielle de renvoi.In an alternative embodiment, the lifting members of the flexible assembly on the leg-to-foot side of the box spring consist of at least two pivoting levers bearing under the flexible strip, levers whose bent ends at their pivots are connected between them by a return rod.

D'autres caractéristiques particulières et avantages de l'invention ressortiront de la description suivante d'exemples de réalisations qui doivent être considérés de façon non limitative et qui font référence aux dessins annexés qui représentent :Other particular characteristics and advantages of the invention will emerge from the following description of examples of embodiments which must be considered in a nonlimiting manner and which refer to the appended drawings which represent:

Figures 1 et 2 des vues en élévation d'un sommier déformable respectivement en position plane et en position relevée.Figures 1 and 2 are elevational views of a deformable bed base respectively in the flat position and in the raised position.

Figures 3 et 4 des vues en élévation d'une variante de réalisation de la partie jambe-pied respectivement en position plane et en position relevée.Figures 3 and 4 elevational views of an alternative embodiment of the leg-foot part respectively in the flat position and in the raised position.

On voit sur les figures 1 et 2 le châssis fixe 1 d'un lit, équipé de cornières latérales s'étendant sur toute la longueur du châssis, qui constituent le socle-support rigide 2 du sommier déformable. Ce dernier est constitué de deux bandes latérale flexibles 3 qui, dans la position représentée à la figure 1 reposent horizontalement sur le socle 2. Sur ces bandes sont fixés de place en place à intervalles réguliers ou non des embouts 4 destinés à recevoir des lattes transversales non représentées sur lesquelles repose le matelas. Une latte 14 de plus grande largeur est en outre prévue entre les bandes 3 à chaque extrémité.We see in Figures 1 and 2 the fixed frame 1 of a bed, equipped with side angles extending over the entire length of the frame, which constitute the rigid support base 2 of the deformable bed base. The latter consists of two flexible lateral bands 3 which, in the position shown in Figure 1 rest horizontally on the base 2. On these bands are fixed from place to place at regular intervals or not, ends 4 intended to receive transverse slats not shown on which the mattress rests. A slat 14 of greater width is further provided between the strips 3 at each end.

La partie buste du sommier est représentée à gauche des figures et la partie jambe-pied est à droite. A proximité du centre du sommier sous chaque cornière formant le socle 2 est fixée une rampe circulaire 5 dont la concavité est tournée vers le haut. La rampe est creusée latéralement d'une rigole 6 servant de guide à deux ergots 7 montés à l'extrémité d'un support profilé 8 qui se développe sous le socle jusqu'à l'extrémité gauche du sommier (figure 1). En variante de la rampe circulaire et des ergots, on pourrait aussi utiliser tout autre système capable de créer virtuellement (système de bielles..) ou réellement un axe d'articulation.The chest part of the box spring is shown on the left of the figures and the leg-foot part is on the right. Near the center of the box spring under each angle iron forming the base 2 is fixed a circular ramp 5 whose concavity is turned upwards. The ramp is hollowed out laterally with a channel 6 serving as a guide for two lugs 7 mounted at the end of a profiled support 8 which develops under the base to the left end of the bed base (Figure 1). As a variant of the circular ramp and the lugs, one could also use any other system capable of creating virtually (connecting rod system, etc.) or actually an axis of articulation.

On remarquera que ledit profilé 8 présente une face supérieure arrondie très ergonomique à concavité tournée vers le haut. Il y a de chaque côté du lit un tel support profilé qui se trouve donc au-dessous de la bande flexible 3, et une latte fixe 9 relie l'extrémité de chacun des profilés.It will be noted that said section 8 has a very ergonomic rounded upper face with concavity facing upwards. There is on each side of the bed such a profiled support which is therefore below the flexible strip 3, and a fixed slat 9 connects the end of each of the profiles.

Par ailleurs, sur le châssis fixe est montée transversalement une barre de commande 10 entraînée en rotation par un levier moteur 11 sous l'action d'un moteur non représenté.Furthermore, on the fixed frame is transversely mounted a control bar 10 rotated by a motor lever 11 under the action of a motor not shown.

Sur chaque extrémité de la barre 10 est fixé un bras 12 terminé par un galet 13 qui prend appui sous le support profilé 8.On each end of the bar 10 is fixed an arm 12 terminated by a roller 13 which bears under the profiled support 8.

Lorsque l'utilisateur veut assurer le relevage de la partie buste, le moteur fait tourner la barre 10 qui relève progressivement les bras 12. Les galets 13 assurent le relevage des supports profilés 8 ; ce mouvement de pivotement entraîne le déplacement des ergots 7 à l'intérieur de la rigole 6 jusqu'à la position extrême représentée à la figure 2. Du fait de la rampe circulaire 5, le mouvement de pivotement de chaque support profilé 8 est complété par un coulissement longitudinal de celui-ci en direction de la tête de lit.When the user wants to ensure the lifting of the bust part, the motor rotates the bar 10 which gradually raises the arms 12. The rollers 13 ensure the lifting of the profiled supports 8; this pivoting movement causes the lugs 7 to move inside the channel 6 to the extreme position shown in FIG. 2. Due to the circular ramp 5, the pivoting movement of each profiled support 8 is completed by a longitudinal sliding thereof towards the headboard.

La latte fixe 9 dépasse alors de la latte d'extrémité 14 des bandes 3, ce qui permet d'éviter le débordement du matelas par rapport au sommier.The fixed slat 9 then protrudes from the end slat 14 of the strips 3, which makes it possible to prevent the mattress from overflowing relative to the bed base.

Au fur et à mesure de la rotation des supports profilés 8 qui sont des pièces rigides, les bandes flexibles s'appliquent sur ces supports et épousent leur profil arrondi. Quel que soit le degré de relevage le buste de l'utilisateur est parfaitement maintenu grâce à la forme arrondie du sommier et du matelas qu'il supporte. Durant ce mouvement les galets 13 roulent sous les parties inférieures desdits profilés.As the profiled supports 8 which are rigid parts are rotated, the flexible bands are applied to these supports and follow their rounded profile. Whatever the degree of lifting, the user's bust is perfectly maintained thanks to the rounded shape of the box spring and the mattress it supports. During this movement the rollers 13 roll under the lower parts of said sections.

La partie jambe-pied visible à droite des figures dispose également de supports ergonomiques 15 dont le profil diffère sensiblement du profil 8 dans la mesure où il montre une première partie AB à concavité tournée vers le haut suivie d'une partie BC à concavité tournée vers le bas. Ces deux parties correspondent à l'appui respectivement des cuisses et des pieds de l'utilisateur. Le support profilé 15 visible à la figure 1 en position effacée sous le socle, peut pivoter autour d'un axe fixe horizontal 6 localisé sensiblement au milieu du châssis près de la rampe circulaire 5. Ledit support profilé repose par sa face inférieure sur un galet 17 monté en bout d'un bras pivotant 18 entraîné en rotation par une barre transversale de commande 19, également manoeuvrée par un levier moteur 20.The leg-foot part visible on the right of the figures also has ergonomic supports 15 whose profile differs appreciably from profile 8 in so far as it shows a first part AB with concavity turned upwards followed by a part BC with concavity turned towards the bottom. These two parts correspond to the support respectively of the thighs and feet of the user. The profiled support 15 visible in Figure 1 in the erased position under the base, can pivot about a horizontal fixed axis 6 located substantially in the middle of the chassis near the circular ramp 5. Said profiled support rests on its underside on a roller 17 mounted at the end of a pivoting arm 18 driven in rotation by a transverse control bar 19, also maneuvered by a motor lever 20.

Comme pour la partie buste, le relevage du support ergonomique 15 entraîne le déplacement de la bande flexible 3 correspondante qui va épouser son profil comme on le voit à la figure 2.As for the bust part, the lifting of the ergonomic support 15 causes the displacement of the corresponding flexible band 3 which will match its profile as seen in FIG. 2.

Les pièces pivotantes précédemment décrites sont avantageusement disposées des deux côtés du sommier de façon à agir simultanément sur les deux bandes flexibles latérales 3.The pivoting parts described above are advantageously arranged on both sides of the bed base so as to act simultaneously on the two lateral flexible bands 3.

En variante de réalisation non représentée, les bandes flexibles 3 sont remplacées par des maillons rigides articulés entre eux un peu à la manière d'une chaîne de bicyclette. Les embouts des lattes transversales sont fixés de place en place sur les maillons. Ces chaînes à maillons épousent le profil des supports ergonomiques, tout à fait comme les bandes flexibles.In an alternative embodiment not shown, the flexible bands 3 are replaced by rigid links hinged together a bit like a bicycle chain. The ends of the transverse slats are fixed from place to place on the links. These link chains follow the profile of ergonomic supports, just like flexible bands.

L'utilisateur peut bien évidemment régler à sa convenance et indépendamment la partie buste et la partie jambe-pied du sommier déformable.The user can of course adjust the bust part and the leg-to-foot part of the deformable bed base as desired and independently.

Quelle que soit la hauteur donnée aux supports profilés, le sommier sera toujours en appui sur des parties arrondies ne présentant pas d'inflexion ce qui améliore nettement le confort.Whatever the height given to the profiled supports, the box spring will always be supported on rounded parts having no inflection which clearly improves comfort.

Les figures 3 et 4 illustrent une variante de réalisation de la partie jambe-pied du sommier.Figures 3 and 4 illustrate an alternative embodiment of the leg-foot part of the bed base.

Le support ergonomique précèdent est remplacé par des leviers de commande qui exercent une précontrainte sur la bande flexible. Dans le cas représenté il y en a deux. Un premier levier pivotant 21 est entraîné en rotation par une barre transversale de commande 22. Il porte à son extrémité un galet 23 qui vient en appui directement sous la bande flexible 3. Un second levier pivotant 24 s'articule selon un axe 25 sur l'extrémité de la bande 3, et peut tourner autour d'un point fixe 26 solidaire du châssis. Les extrémités des deux leviers 21, 24 coudées au niveau de leurs pivots sont reliées entre elles par une bielle de renvoi 27.The preceding ergonomic support is replaced by control levers which exert a prestress on the flexible strip. In the case shown there are two. A first pivoting lever 21 is rotated by a transverse control bar 22. It carries at its end a roller 23 which comes to bear directly under the flexible strip 3. A second pivoting lever 24 is articulated along an axis 25 on the end of the strip 3, and can rotate around a fixed point 26 secured to the chassis. The ends of the two levers 21, 24 bent at their pivots are connected together by a return rod 27.

Dans la position de la figure 3 les leviers pivotants se trouvent au-dessous du socle support rigide 2 sur lequel repose la bande flexible 3.In the position of FIG. 3, the pivoting levers are located below the rigid support base 2 on which the flexible strip 3 rests.

Dès qu'on fait agir le moteur dans le sens d'une rotation de la barre de commande 22, le levier pivotant 21 va soulever par son galet 23 la bande flexible qui s'infléchit vers le haut. Du fait de la bielle de renvoi 27, le mouvement se transmet à l'autre levier pivotant 24 qui soulève également l'extrémité de la bande flexible. Mais celle-ci étant solidaire du levier par l'axe 25 subira une contrainte qui va se traduire par une courbure entre son extrémité et le galet 23 comme on le voit clairement à la figure 4. La précontrainte exercée entre ces deux points d'appui maintiendra la cambrure arrondie de la bande flexible donnant ainsi à la partie jambe-pied du sommier un profil ergonomique équivalent à celui obtenu avec le support précédemment décrit.As soon as the motor is made to act in the direction of rotation of the control bar 22, the pivoting lever 21 will raise by its roller 23 the flexible band which bends upwards. Due to the return rod 27, the movement is transmitted to the other pivoting lever 24 which also lifts the end of the flexible strip. But the latter being secured to the lever by the axis 25 will undergo a stress which will result in a curvature between its end and the roller 23 as can be clearly seen in FIG. 4. The prestressing exerted between these two support points will maintain the rounded camber of the flexible band, thus giving the leg-to-foot part of the bed base an ergonomic profile equivalent to that obtained with the support described above.

Les cas de figure décrits précédemment se rapportent à des mécanismes dans lesquels l'élément souple servant de support au matelas est formé de deux bandes latérales flexibles. En variante de réalisation non représentée, ces bandes pourraient être remplacées par une unique surface souple qui couvrirait toute la largeur du lit. Les embouts 4 seraient par exemple agrafés sur les côtés de ladite surface. Les organes relevages resteraient avantageusement localisés sur les côtés du lit. Cette surface souple présente l'avantage, notamment, d'occulter les mécanismes disposés sur le châssis.The cases described above relate to mechanisms in which the flexible element serving to support the mattress is formed by two flexible lateral bands. In an alternative embodiment not shown, these bands could be replaced by a single flexible surface which would cover the entire width of the bed. The end pieces 4 would for example be stapled to the sides of said surface. The lifting bodies would remain advantageously located on the sides of the bed. This flexible surface has the advantage, in particular, of hiding the mechanisms arranged on the chassis.
