Abstract

The lounger (10), comprising a rectangular frame with a headboard (14) at one end, has an adjustable surface created by a series of transverse hinged slats (18), each made up of a support (18a) and a body section (18b). The surface adjustment is controlled by a mechanism (22) that can move an end slat (26) relative to the headboard to create a curve. The foot end of the adjustable surface can also be moved by levers to create a raised leg rest.

Description

La présente invention concerne les lits de relaxation comportant un plan de couchage dont une partie au moins peut-être relevée.The present invention relates to relaxation beds having a sleeping surface of which at least a portion may be raised.

L'invention concerne plus particulièrement un lit de relaxation comportant un cadre rectangulaire définissant une surface, un accotoir s'étendant selon une direction longitudinale tout en étant fixé à l'une des extrémités du cadre et un plan de couchage déformable apte à prendre appui sur le cadre, ledit lit comprenant en outre un dispositif de pliage pour plier le plan de couchage dans le sens de sa longueur.The invention more particularly relates to a relaxation bed comprising a rectangular frame defining a surface, an armrest extending in a longitudinal direction while being attached to one end of the frame and a deformable coating plane adapted to bear on the frame, said bed further comprising a folding device for folding the coating plane in the direction of its length.

Il est connu, notamment au travers du document DE 195 32 671 , que dans les lits de relaxation, le plan de couchage comporte un sommier ayant une partie « tête » où est située la tête de l'utilisateur, ainsi qu'une partie « pieds » où sont situés les pieds de l'utilisateur, la partie « tête » et/ou la partie « pieds » du cadre pouvant être relevée(s). Ceci est réalisé en général en utilisant un cadre à plans brisés dont les éléments mobiles sont actionnés par un mécanisme approprié. Ce cadre supporte un sommier articulé à lattes susceptible d'être plié, dans le sens longitudinal, au moins dans certaines zones, ce sommier définissant le plan de couchage.He is known, particularly through the document DE 195 32 671 , that in the relaxation beds, the sleeping surface comprises a bed base having a "head" part where the head of the user is located, and a "feet" part where the user's feet are located, the part "head" and / or the part "feet" of the frame can be raised (s). This is generally done using a broken plane frame whose moving parts are actuated by a suitable mechanism. This frame supports an articulated slatted bed base capable of being folded, in the longitudinal direction, at least in certain areas, this bed frame defining the sleeping plane.

Selon l'invention, l'accotoir peut être situé indifféremment à l'une ou l'autre des deux extrémités du cadre, c'est-à-dire en amont de la partie tête ou en aval de la partie pieds.According to the invention, the armrest can be located indifferently to one or other of the two ends of the frame, that is to say upstream of the head portion or downstream of the foot portion.

Lorsqu'un matelas est posé sur un tel plan de couchage et lorsque la partie tête et/ou la partie pieds n'est (ne sont) pas relevée(s), le matelas s'étend sur la surface plane formée par le plan de couchage. Dans cette configuration, on comprend que le matelas épouse parfaitement le plan de couchage.When a mattress is placed on such a sleeping surface and when the head portion and / or the foot portion is (are) not raised (s), the mattress extends on the flat surface formed by the plane of sleeping. In this configuration, it is understood that the mattress perfectly matches the sleeping plane.

En revanche, lorsque la partie « tête » et/ou la partie « pieds » est (sont) relevée(s), le plan de couchage se présente sous la forme d'un plan brisé comportant une pluralité de pliures constituant des zones de discontinuités pour le plan de couchage.On the other hand, when the part "head" and / or the part "feet" is (are) raised (s), the sleeping plan is in the form of a broken plane having a plurality of folds constituting zones of discontinuities for the sleeping plan.

Du fait notamment de son épaisseur, on comprend que le matelas ne peut pas bien épouser la forme du plan de couchage, à savoir chacune des parties du plan brisé.Due in particular to its thickness, it is understood that the mattress can not marry well the shape of the sleeping surface, namely each part of the broken plane.

En pratique, on constate que le matelas décolle localement du plan de couchage et qu'il a tendance à être comprimé sur lui-même lorsque les parties tête et pieds sont simultanément relevées.In practice, it is found that the mattress takes off locally from the sleeping surface and that it tends to be compressed on itself when the head and feet are simultaneously raised.

II en résulte que l'utilisateur est également comprimé ce qui nuit à son confort.As a result, the user is also compressed, which is detrimental to his comfort.

L'invention se propose de remédier à ces inconvénients.The invention proposes to remedy these drawbacks.

Dans ce but, le plan de couchage comporte une pluralité de lattes parallèles articulées entre elles de manière à former un rideau de lattes apte à être cintré, le dispositif de pliage comporte des moyens de déplacement aptes à déplacer une latte d'extrémité du plan de couchage proche de l'accotoir selon une direction parallèle à la direction longitudinale de cet accotoir de manière à cintrer le rideau de lattes, tandis qu'une première partie du plan de couchage s'étend dans la surface du cadre.For this purpose, the coating plane comprises a plurality of parallel slats articulated to each other so as to form a curtain of slats adapted to be bent, the folding device comprises displacement means able to move an end slat of the plane of sleeping close to the armrest in a direction parallel to the longitudinal direction of the armrest so as to bend the curtain of slats, while a first portion of the sleeping surface extends into the surface of the frame.

On comprend que le dispositif de pliage constitue un dispositif de cintrage pour cintrer le plan de couchage, c'est-à-dire pour donner une forme courbe d'au moins une partie de ce dernier.It is understood that the folding device is a bending device for bending the coating plane, that is to say to give a curved shape of at least a portion of the latter.

Naturellement, la direction longitudinale de l'accotoir n'est pas comprise dans la surface du cadre rectangulaire mais, de manière préférentielle, cette direction s'étend sensiblement orthogonalement à la surface du cadre rectangulaire.Naturally, the longitudinal direction of the armrest is not included in the surface of the rectangular frame but, preferably, this direction extends substantially orthogonal to the surface of the rectangular frame.

On comprend donc que les moyens de déplacement permettent d'élever la latte d'extrémité par rapport à la surface du cadre.It is therefore understood that the displacement means allow to raise the end lath relative to the surface of the frame.

Grâce à l'invention, le rideau de lattes peut se cintrer, c'est-à-dire qu'il peut prendre une forme courbe, contrairement aux dispositifs connus où l'on plie le plan de couchage.Thanks to the invention, the curtain of slats can bend, that is to say it can take a curved shape, unlike known devices where the folding bed is folded.

De manière préférentielle, la latte d'extrémité demeure pendant son déplacement dans un plan sensiblement parallèle à la surface du cadre.Preferably, the end lath remains during its movement in a plane substantially parallel to the surface of the frame.

Lorsqu'on déplace la latte d'extrémité en l'éloignant de la surface du cadre, on comprend que le rideau de lattes se soulève localement, se déforme en se cintrant entre la latte d'extrémité et la première partie du plan de couchage en prenant de façon naturelle la forme d'une courbe continue.When the end lath is moved away from the surface of the frame, it is understood that the curtain of laths is raised locally, is deformed by bending between the end lath and the first part of the sleeping surface. naturally taking the form of a continuous curve.

De même, lorsqu'on déplace la latte d'extrémité en la rapprochant de la surface du cadre, on comprend que le rideau de lattes tend à reprendre sa forme plane.Similarly, when moving the end lath closer to the surface of the frame, it is understood that the curtain of slats tends to resume its flat shape.

On comprend également que la courbure du plan de couchage varie continûment lors du déplacement de la latte d'extrémité et, par suite, l'utilisateur peut avantageusement choisir la courbure du plan de couchage en réglant le déplacement de la latte d'extrémité.It is also understood that the curvature of the coating plane varies continuously during the displacement of the end lath and, by subsequently, the user can advantageously choose the curvature of the coating plane by adjusting the displacement of the end lath.

Contrairement aux dispositifs de l'art antérieur mentionnés ci-dessus, on comprend que grâce à la présente invention, le matelas épouse naturellement le plan de couchage, même lorsque celui est relevé.Unlike the devices of the prior art mentioned above, it is understood that thanks to the present invention, the mattress naturally marries the sleeping surface, even when it is raised.

En effet, la courbure du plan de couchage tend à enrouler le matelas sur lui-même, de façon naturelle, si bien que le matelas n'a pas tendance à décoller du plan de couchage, ni à être comprimé sur lui-même.Indeed, the curvature of the sleeping surface tends to roll up the mattress on itself, in a natural way, so that the mattress does not tend to take off from the sleeping surface, nor to be compressed on itself.

Il en résulte que lorsqu'on cintre le plan de couchage, le matelas se courbe de façon naturelle, améliorant ainsi l'ergonomie et le confort du lit de relaxation.As a result, when bending the sleeping surface, the mattress curves in a natural way, thus improving the ergonomics and comfort of the relaxation bed.

Comme l'accotoir est généralement situé derrière la tête de l'utilisateur, la latte d'extrémité se trouve généralement du côté de la partie tête du plan de couchage.As the armrest is generally located behind the user's head, the end lath is generally on the side of the head portion of the sleeping plane.

Selon une variante, on peut également prévoir que l'accotoir et la latte d'extrémité se trouvent du côté de la partie pieds du plan de couchage. Dans ce cas, le déplacement de la latte d'extrémité entraîne le soulèvement de la partie pied du plan de couchage.According to a variant, it is also possible that the armrest and the end lath are on the side of the foot portion of the sleeping plane. In this case, the displacement of the end slat causes the lifting of the foot portion of the sleeping surface.

Avantageusement, le cadre comporte des moyens de guidage aptes à guider le déplacement de la première partie du plan de couchage selon la direction longitudinale du cadre, lorsque la latte d'extrémité est déplacée.Advantageously, the frame comprises guiding means capable of guiding the displacement of the first part of the coating plane in the longitudinal direction of the frame, when the end lath is moved.

Lorsque le rideau de lattes est soulevé du fait de l'éloignement de la latte d'extrémité de la surface du cadre, on comprend que la première partie du plan de couchage se déplace simultanément vers l'accotoir. Réciproquement, lorsque le rideau de lattes est abaissé du fait du rapprochement de la latte d'extrémité du cadre, on comprend que la première partie du plan de couchage se déplace simultanément vers l'extrémité de la surface du cadre opposée à l'accotoir.When the curtain of slats is raised due to the distance of the end slat from the surface of the frame, it is understood that the first part of the coating plane moves simultaneously towards the armrest. Conversely, when the curtain of slats is lowered due to the approximation of the end slat of the frame, it is understood that the first part of the coating plane moves simultaneously towards the end of the surface of the frame opposite the armrest.

Les moyens de guidage permettent de s'assurer que le plan de couchage reste bien positionné par rapport au cadre lors du déplacement de la latte d'extrémité.The guiding means make it possible to ensure that the coating plane remains well positioned with respect to the frame during the displacement of the end lath.

Avantageusement, les moyens de déplacement sont essentiellement logés dans l'accotoir.Advantageously, the displacement means are essentially housed in the armrest.

Dans les lits de relaxation connus, le dispositif de cintrage est habituellement disposé sous le cadre et, lorsque le plan de couchage est cintré, le dispositif est généralement visible et, par conséquent, rend le lit de relaxation peu esthétique.In known relaxation beds, the bending device is usually arranged under the frame and, when the bedding is bent, the device is generally visible and, therefore, makes the relaxation bed unattractive.

En revanche, lorsqu'ils sont essentiellement logés dans l'accotoir, les moyens de déplacement et partant, le dispositif de cintrage n'est pas visible, quel que soit la configuration du lit.On the other hand, when they are essentially housed in the armrest, the moving means and therefore the bending device is not visible, whatever the configuration of the bed.

II en résulte une amélioration avantageuse de l'aspect extérieur du lit de relaxation selon l'invention, généralement destiné à des utilisateurs exigeants en ce qui concerne l'esthétique du lit.This results in an advantageous improvement of the external appearance of the relaxation bed according to the invention, generally intended for demanding users as regards the aesthetics of the bed.

Avantageusement, l'accotoir est pourvu de moyens pour guider le déplacement de la latte d'extrémité.Advantageously, the armrest is provided with means for guiding the movement of the end lath.

De préférence, ces moyens s'étendent selon la direction longitudinale de l'accotoir et permettent également de relier les moyens de déplacement à la latte d'extrémité.Preferably, these means extend in the longitudinal direction of the armrest and also make it possible to connect the displacement means to the end lath.

Selon une autre variante, le lit selon l'invention comporte en outre des moyens pour soulever une deuxième partie du plan de couchage située à l'extrémité du plan de couchage qui est opposée à l'accotoir.According to another variant, the bed according to the invention further comprises means for lifting a second portion of the sleeping surface located at the end of the sleeping surface which is opposite to the armrest.

De manière préférentielle, ces moyens permettent de soulever la partie pieds du plan de couchage.Preferably, these means make it possible to lift the feet part of the sleeping surface.

Naturellement, il est possible de soulever simultanément ou indépendamment les parties tête et pieds du plan de couchage.Naturally, it is possible to lift simultaneously or independently the head and foot parts of the sleeping surface.

Un lit de relaxation 10 selon l'invention est représenté sur les figures 1 à 10.A relaxation bed 10 according to the invention is represented on the Figures 1 to 10 .

Un tel lit de relaxation 10, visible sur la figure 1 , comporte un cadre rectangulaire 12 s'étendant selon une direction longitudinale D, un accotoir 14 fixé à l'une des deux extrémités du cadre 12 et un plan de couchage 20 apte à supporter un matelas (non représenté ici).Such a relaxation bed 10, visible on the figure 1 , comprises a rectangular frame 12 extending in a longitudinal direction D, an armrest 14 attached to one of the two ends of the frame 12 and a sleeping surface 20 adapted to support a mattress (not shown here).

Le cadre 12 comporte notamment deux longs pans 13 s'étendant longitudinalement et définissant deux bords opposés du cadre 12.The frame 12 comprises in particular two long sections 13 extending longitudinally and defining two opposite edges of the frame 12.

Comme on le voit sur la figure 1 , le plan de couchage 20 comporte une pluralité de lattes 18 parallèles s'étendant transversalement par rapport au cadre 12.As we see on the figure 1 , the coating plane 20 comprises a plurality of parallel slats 18 extending transversely with respect to the frame 12.

Par ailleurs, comme on peut le constater sur les figures 1 à 10, chacune des lattes 18 comporte de préférence mais non nécessairement un support de latte 18a et un corps de latte 18b et que les lattes 18 sont reliées entre elles par l'intermédiaire de leurs supports 1 8a, l'articulation se faisant entre les supports de lattes 18a.Moreover, as can be seen from the Figures 1 to 10 each of the slats 18 preferably but not necessarily includes a slat support 18a and a slab body 18b and that the slats 18 are interconnected by means of their supports 18a, the articulation being between the supports of slats 18a.

Ces lattes 18 sont avantageusement articulées entre elles de manière à former un rideau de lattes 21 , c'est-à-dire une structure apte à prendre une forme courbe lorsqu'elle est déformée.These slats 18 are advantageously hinged together to form a curtain slats 21, that is to say a structure adapted to take a curved shape when it is deformed.

Ce rideau de lattes 21 est donc cintrable contrairement aux sommiers multi-plans pliables connus dans l'art antérieur.This curtain of slats 21 is therefore bendable unlike foldable multi-plane sommiers known in the prior art.

Autrement dit, deux lattes adjacentes du rideau de lattes 21 peuvent pivoter l'une par rapport à l'autre autour d'un axe parallèle à la direction longitudinale des lattes.In other words, two adjacent slats of the slat curtain 21 can pivot relative to each other about an axis parallel to the longitudinal direction of the slats.

Toutefois, pour des raisons détaillées ci-après, d'autres lattes 18 du plan de couchage 20 peuvent être solidarisées entre elles de manière à former une portion plane du plan de couchage 20.However, for reasons detailed below, other slats 18 of the coating plane 20 may be joined to each other so as to form a flat portion of the coating plane 20.

L'accotoir 14 présente sensiblement la forme d'une plaque rectangulaire épaisse qui s'étend de manière préférentielle orthogonalement par rapport à la surface du cadre 12. Les accotoirs sont connus en eux-mêmes et forment habituellement une zone d'appui pour les oreillers ou traversins.The armrest 14 has substantially the shape of a thick rectangular plate which preferably extends orthogonally with respect to the surface of the frame 12. The armrests are known in themselves and usually form a support zone for the pillows or bolsters.

Dans les exemples représentés sur les figures 1 à 10, l'accotoir 14 est disposé en tête du lit de relaxation 10, mais on pourrait très bien prévoir, sans sortir du cadre de l'invention, que cet accotoir soit disposé à l'extrémité opposé, à savoir en pied de lit.In the examples shown on the Figures 1 to 10 the armrest 14 is disposed at the head of the relaxation bed 10, but it could be provided without departing from the scope of the invention, this armrest is disposed at the opposite end, namely at the foot of bed.

Autrement dit, l'accotoir 14 n'est pas nécessairement fixé en tête du lit 10.In other words, the armrest 14 is not necessarily fixed at the head of the bed 10.

Le lit de relaxation 10 selon l'invention comporte un dispositif de pliage qui constitue un dispositif de cintrage 22 que l'on va maintenant décrire plus en détail.The relaxation bed 10 according to the invention comprises a folding device which constitutes a bending device 22 which will now be described in more detail.

Comme on le voit sur la figure 2, le plan de couchage 20 est apte à se déplacer par rapport au cadre 12 selon sa direction longitudinale.As we see on the figure 2 , the coating plane 20 is able to move relative to the frame 12 in its longitudinal direction.

Pour ce faire, une première partie 25 du plan de couchage 20 est montée coulissante sur des rails 24 fixés aux longs pans 13, à l'intérieur du cadre 12, ces rails formant des moyens de guidage en translation pour cette première partie 25 du plan de couchage 20.To do this, a first part 25 of the coating plane 20 is slidably mounted on rails 24 fixed to the long sections 13, inside the frame 12, these rails forming translational guiding means for this first part 25 of the plane sleeping 20.

On comprend donc que cette première partie 25 du plan de couchage 20 s'étend dans la surface du cadre 12.It is therefore understood that this first portion 25 of the coating plane 20 extends in the surface of the frame 12.

En outre, l'extrémité du plan de couchage qui est située à proximité de l'accotoir est apte à être soulevée par rapport à la surface du cadre 12, comme on le voit notamment sur les figures 2 et 4, les rails 24 servant alors de moyens d'appui pour cette partie du plan de couchage 20.In addition, the end of the sleeping plane which is located near the armrest is adapted to be raised relative to the surface of the frame 12, as seen in particular on the figures 2 and 4 , the rails 24 then serving as support means for this part of the coating plane 20.

Sur la figure 1 , on a représenté le lit de relaxation 10 selon l'invention lorsque le plan de couchage 20 n'est pas cintré, c'est-à-dire lorsqu'il s'étend dans un plan sensiblement parallèle à la surface du cadre.On the figure 1 , the relaxation bed 10 according to the invention is shown when the coating plane 20 is not bent, that is to say when it extends in a plane substantially parallel to the surface of the frame.

Tandis que sur la figure 2, on a représenté le lit de relaxation 10 selon l'invention lorsque le plan de couchage 20 est cintré dans le sens de sa longueur.While on the figure 2 the relaxation bed 10 according to the invention is shown when the coating plane 20 is bent in the direction of its length.

Le dispositif de cintrage 22 comporte des moyens de déplacement 23, qui sont de préférence essentiellement logés dans l'accotoir 14.The bending device 22 comprises displacement means 23, which are preferably substantially housed in the armrest 14.

Ces moyens de déplacement sont aptes à déplacer la latte 26 se trouvant à l'extrémité du plan de couchage qui est proche de l'accotoir (cette latte particulière est appelée la latte d'extrémité 26), de telle sorte que celle-ci entraîne dans son déplacement les autres lattes du rideau de lattes 21.These displacement means are able to move the slat 26 located at the end of the coating plane which is close to the armrest (this particular slat is called the end slat 26), so that it leads to in its displacement the other slats of the curtain of slats 21.

Les moyens de déplacement 23, qui seront décrits plus en détail ci-après, permettent donc de lever et d'abaisser la latte d'extrémité 26 par rapport à la surface du cadre 12.The displacement means 23, which will be described in more detail below, thus make it possible to raise and lower the end lath 26 with respect to the surface of the frame 12.

En outre, l'accotoir 14 est de préférence pourvu de fentes 28 s'étendant selon la direction longitudinale de l'accotoir 14, ces fentes formant des moyens pour guider en translation le déplacement de la latte d'extrémité 26 dans la direction longitudinale de l'accotoir 14.In addition, the armrest 14 is preferably provided with slots 28 extending in the longitudinal direction of the armrest 14, these slots forming means for guiding in translation the displacement of the end lath 26 in the longitudinal direction of the armrest 14. the armrest 14.

De manière préférentielle, la latte d'extrémité 26 est fixée aux moyens de déplacement 23 par l'intermédiaire de tiges 30 traversant l'accotoir 14 par les fentes 28.Preferably, the end lath 26 is fixed to the displacement means 23 via rods 30 passing through the armrest 14 through the slots 28.

On comprend que ces tiges 30 sont aptes à déplacer la latte d'extrémité 26 selon la direction longitudinale de l'accotoir 14, entre une position basse représentée sur la figure 1 et une position haute représentée sur la figure 2.It is understood that these rods 30 are able to move the end lath 26 in the longitudinal direction of the armrest 14, between a low position shown on the figure 1 and a high position shown on the figure 2 .

Lorsque la latte d'extrémité 26 est déplacée depuis la position basse vers la position haute, on comprend que l'extrémité du rideau de lattes 21 proche de l'accotoir se soulève par rapport à la surface du cadre 12, dans le sens de la flèche représentée sur la figure 2.When the end lath 26 is moved from the low position to the high position, it is understood that the end of the lath curtain 21 close to the armrest is raised relative to the surface of the frame 12, in the direction of the arrow shown on the figure 2 .

Simultanément, la première partie du plan de couchage se déplace vers l'accotoir 14 tout en étant guidée par les rails 24.Simultaneously, the first part of the sleeping surface moves towards armrest 14 while being guided by rails 24.

Il en résulte que le rideau de lattes, du fait de sa structure particulière, se déforme sous l'action de la pesanteur dans sa partie proche de l'accotoir, de manière à prendre naturellement la forme d'une courbe continue lorsque la latte d'extrémité est soulevée par rapport à la surface du cadre 12.As a result, the curtain of laths, due to its particular structure, deforms under the action of gravity in its part near the armrest, so as to naturally take the form of a continuous curve when the lath of end is raised relative to the surface of the frame 12.

Lorsqu'un matelas (non représenté ici) est posé sur le plan de couchage et lorsque le plan de couchage est cintré, on conçoit que ce matelas est courbé de façon naturelle en ayant tendance à s'enrouler sur lui-même. De la sorte, le matelas épouse parfaitement la courbure du rideau de lattes 21 , améliorant de la sorte l'ergonomie et le confort du lit de relaxation 10 selon l'invention.When a mattress (not shown here) is placed on the sleeping surface and when the sleeping surface is curved, it is conceivable that this mattress is curved in a natural way with a tendency to curl on itself. In this way, the mattress perfectly matches the curvature of the curtain slats 21, thereby improving the ergonomics and comfort of the relaxation bed 10 according to the invention.

De manière préférentielle, le plan de couchage comporte à son extrémité opposée à l'accotoir des moyens de butée (non représentés ici) afin de maintenir le matelas sur le plan de couchage lorsque celui-ci est déformé. Ces moyens empêchent notamment le matelas de glisser dans la direction longitudinale du lit lorsque la partie tête du plan de couchage est relevée.Preferably, the sleeping surface has at its end opposite the armrest stop means (not shown here) to maintain the mattress on the bed when it is deformed. These means prevent in particular the mattress from sliding in the longitudinal direction of the bed when the head portion of the sleeping plane is raised.

Selon une variante représentée sur les figures 3 et 4, le lit de relaxation 10 comporte en outre des moyens 32, 36 pour soulever une deuxième partie 34 du plan de couchage située à l'extrémité du plan de couchage 20 qui est opposée à l'accotoir 14.According to a variant represented on the Figures 3 and 4 , the relaxation bed 10 further comprises means 32, 36 for lifting a second portion 34 of the coating plane located at the end of the coating plane 20 which is opposite to the armrest 14.

Sur la figure 3, on a représenté le lit de relaxation 10 dans une configuration dans laquelle la latte d'extrémité 26 est en position basse et dans laquelle la deuxième partie 34 du plan de couchage 20 est soulevée.On the figure 3 , there is shown the relaxation bed 10 in a configuration in which the end lath 26 is in the low position and in which the second portion 34 of the coating plane 20 is raised.

Cette deuxième partie 34 correspond de préférence à la partie pieds du plan de couchage 20.This second portion 34 preferably corresponds to the foot portion of the coating plane 20.

Comme on le voit sur l'exemple représenté sur les figures 3 et 4, la deuxième partie 34 peut être soulevée en restant sensiblement parallèle à la surface du cadre. Dans ce cas, on peut prévoir que quelques lattes situées à l'extrémité de la deuxième partie soient solidarisées entre elles.As can be seen in the example shown on the Figures 3 and 4 the second part 34 can be raised while remaining substantially parallel to the surface of the frame. In this case, it can be provided that some slats located at the end of the second part are secured to each other.

Les moyens 32, 36 pour soulever cette deuxième partie peuvent comporter des moyens moteurs aptes à faire pivoter deux bras 36 reliés aux lattes de l'extrémité de la deuxième partie 34.The means 32, 36 for lifting this second part may comprise driving means capable of pivoting two arms 36 connected to the slats of the end of the second part 34.

Ces moyens moteurs sont de préférence montés coulissant sur les longs pans 13, de manière à accompagner le déplacement de la deuxième partie 34 lorsque la latte d'extrémité 26 est déplacée, comme cela a été représenté sur la figure 4.These motor means are preferably slidably mounted on the long sides 13, so as to accompany the displacement of the second portion 34 when the end lath 26 is moved, as has been shown on the figure 4 .

A l'aide des figures 5 à 10, on va maintenant décrire plus en détail trois modes de réalisation des moyens de déplacement 23.With the help of Figures 5 to 10 three embodiments of the moving means 23 will now be described in more detail.

Comme on le constate sur ces figures, les moyens de déplacement sont essentiellement logés dans l'accotoir 14, qui, pour ce faire, est avantageusement évidé. Sur les figures, l'accotoir 14 et le cadre 12 sont représentés en traits pointillés, tandis que les moyens de déplacement 23 et le plan de couchage 20 sont représentés en traits continus.As can be seen in these figures, the displacement means are essentially housed in the armrest 14, which, for this purpose, is advantageously hollowed out. In the figures, the armrest 14 and the frame 12 are shown in dashed lines, while the displacement means 23 and the coating plane 20 are shown in solid lines.

Les figures 5 et 6 représentent un premier mode de réalisation des moyens de déplacement 23.The Figures 5 and 6 represent a first embodiment of the displacement means 23.

Dans leur premier mode de réalisation, les moyens de déplacement 23 se présentent sous la forme d'un cric 200 comportant un vérin 202 fixé à la partie inférieure 204 de l'accotoir 14.In their first embodiment, the displacement means 23 are in the form of a jack 200 comprising a jack 202 attached to the lower portion 204 of the armrest 14.

Le cric 200 comporte deux éléments en « X » 206, 208 déformables, chacun des éléments en « X » comportant deux bras 210, 210' : à savoir un premier élément en « X » 206 disposé dans la partie inférieure 204 de l'accotoir 14 et un second élément en « X » 208 disposé dans la partie supérieure 205 de l'accotoir 14.The jack 200 comprises two elements in "X" 206, 208 deformable, each of the elements in "X" having two arms 210, 210 ': namely a first element "X" 206 disposed in the lower part 204 of the armrest 14 and a second element "X" 208 disposed in the upper portion 205 of the armrest 14.

Les éléments en « X » 206, 208 s'étendent tout deux dans le plan de l'accotoir 14, comme cela est bien visible sur la figure 6.The elements "X" 206, 208 both extend in the plane of the armrest 14, as is clearly visible on the figure 6 .

Par ailleurs, le premier élément en « X » 206 est relié au second élément en « X » par l'intermédiaire d'un premier chariot 212 mobile sur des premiers rails 214 fixé à une première liaison pivot 21 6, le premier chariot 212 et la première liaison pivot connectant les bras 210 du premier élément en « X » aux bras 210' du second élément en « X » 208.Furthermore, the first "X" element 206 is connected to the second "X" element via a first carriage 212 movable on first rails 214 fixed to a first pivot link 21 6, the first carriage 212 and the first pivot connection connecting the arms 210 of the first "X" element to the arms 210 'of the second "X" element 208.

La tige 218 du vérin 202 est fixée à un deuxième chariot 220 mobile sur des deuxièmes rails 222 fixés à la partie inférieure 204 de l'accotoir 14. Un bras 210 est relié au deuxième chariot mobile 220 et à la première liaison pivot 216, tandis que l'autre bras 210 est relié au premier chariot mobile 212 et à une deuxième liaison pivot 224 située à l'extrémité des deuxièmes rails 222, opposée au vérin 202.The rod 218 of the jack 202 is fixed to a second carriage 220 movable on second rails 222 attached to the lower portion 204 of the armrest 14. An arm 210 is connected to the second movable carriage 220 and the first pivot link 216, while that the other arm 210 is connected to the first movable carriage 212 and to a second pivot link 224 located at the end of the second rails 222, opposite the jack 202.

De même, l'un des bras 210' du second élément en « X » est relié à la première liaison 216 et à un troisième chariot 226 mobile sur des troisièmes rails 228, tandis que l'autre bras 210' est relié entre le premier chariot 212 et une troisième liaison pivot 230 situé à l'extrémité des troisièmes rails 228.Similarly, one of the arms 210 'of the second element "X" is connected to the first link 216 and a third carriage 226 mobile on third rails 228, while the other arm 210' is connected between the first carriage 212 and a third pivot link 230 located at the end of the third rails 228.

Par ailleurs, la latte d'extrémité 26 est fixée à un support 213, lui-même étant fixé aux troisièmes rails 228.Furthermore, the end lath 26 is fixed to a support 213, itself being attached to the third rails 228.

Comme on le voit sur la figure 5, lorsque la tige 218 du vérin 202 est en position rentrée, les chariots 212,220 et 226 sont positionnés à l'extrémité opposé à celle des liaisons pivots 216,224 et 230 de telle sorte que le cric 220 est en replié sur lui-même.As we see on the figure 5 when the rod 218 of the cylinder 202 is in the retracted position, the carriages 212,220 and 226 are positioned at the end opposite that of the pivot links 216,224 and 230 so that the jack 220 is folded back on itself.

Il en résulte que le support 213 est positionné dans la partie inférieure de l'accotoir 14 de telle sorte que le rideau de lattes 21 s'étend sensiblement dans un plan parallèle à la surface du cadre 12.As a result, the support 213 is positioned in the lower part of the armrest 14 so that the batten curtain 21 extends substantially in a plane parallel to the surface of the frame 12.

Comme on le voit sur la figure 6, lorsque la tige 218 du vérin 202 est sortie, les chariots 212, 220 et 226 sont déplacés vers les liaisons pivot 216, 224 et 230 de telle sorte que les éléments en « X » 206, 208 se déploient vers la partie supérieure 208 de l'accotoir, déplaçant ainsi le support 213 vers la partie supérieure 205 de l'accotoir 14.As we see on the figure 6 when the rod 218 of the ram 202 is extended, the carriages 212, 220 and 226 are moved to the pivot links 216, 224 and 230 so that the "X" elements 206, 208 are deployed towards the upper portion 208 of the armrest, thus moving the support 213 to the upper part 205 of the armrest 14.

Il en résulte le déplacement de la latte d'extrémité 26 vers la position haute, soulevant ainsi le rideau de lattes 21 par rapport à la surface du cadre 12, comme le schématise la flèche dessinée sur la figure 6.This results in the end batten 26 being displaced towards the upper position, thus raising the curtain of slats 21 with respect to the surface of the frame 12, as shown by the arrow drawn on the figure 6 .

Comme on l'a déjà mentionné, le cric 200 est avantageusement logé dans l'accotoir 14, si bien qu'il n'est pas visible de l'extérieur.As already mentioned, the jack 200 is advantageously housed in the armrest 14, so that it is not visible from the outside.

Les figures 7 et 8 représentent un second mode de réalisation des moyens de déplacement 23.The Figures 7 and 8 represent a second embodiment of the displacement means 23.

Dans leur second mode de réalisation, ces moyens se présentent sous la forme d'une courroie large 300 monté sur deux cylindres 302, 307 fixés respectivement aux parties inférieure 304 et supérieure 305 de l'accotoir 14. Comme on le voit sur les figures 7 et 8, les axes des cylindres 302, 307 s'étendent transversalement à l'accotoir 14, c'est-à-dire selon sa largeur, de telle sorte que les brins de la courroie large 300 s'étendent dans la direction longitudinale de l'accotoir 14.In their second embodiment, these means are in the form of a wide belt 300 mounted on two cylinders 302, 307 respectively fixed to the lower portions 304 and upper 305 of the armrest 14. As can be seen from the Figures 7 and 8 the axes of the cylinders 302, 307 extend transversely to the armrest 14, that is to say along its width, so that the strands of the wide belt 300 extend in the longitudinal direction of the arm armrest 14.

Les moyens de déplacement 23 comportent en outre un bras mobile 306 s'étendant selon la largeur de l'accotoir 14, ce bras 306 étant par ailleurs guidé en translation selon la direction longitudinale de l'accotoir 14 par l'intermédiaire de deux bras 308 qui s'étendent selon la direction longitudinale de l'accotoir 14.The displacement means 23 further comprise a movable arm 306 extending along the width of the armrest 14, this arm 306 being moreover guided in translation in the longitudinal direction of the armrest 14 by means of two arms 308. which extend in the longitudinal direction of the armrest 14.

Le bras mobile 306 est avantageusement fixé à l'un des deux brins de la courroie 300 de telle sorte que l'on peut faire monter et descendre le bras 306 en faisant tourner la courroie 300 dans un sens ou dans l'autre.The movable arm 306 is preferably attached to one of the two strands of the belt 300 so that the arm 306 can be raised and lowered by rotating the belt 300 in one direction or the other.

Par ailleurs, le bras mobile 306 est fixé à la latte d'extrémité 26 par des tiges de fixations. Dès lors, on comprend qu'en faisant tourner la courroie 300, on déplace la latte d'extrémité selon la direction longitudinale de l'accotoir 14.Furthermore, the movable arm 306 is attached to the end lath 26 by fixing rods. Therefore, it is understood that by rotating the belt 300, the end lath is moved in the longitudinal direction of the armrest 14.

La courroie 300, les cylindres 302, 307 et le bras 306 sont avantageusement logés dans l'accotoir 14, si bien qu'ils ne sont pas visibles de l'extérieur.The belt 300, the cylinders 302, 307 and the arm 306 are advantageously housed in the armrest 14, so that they are not visible from the outside.

Selon une première variante (non représentée ici) du deuxième mode de réalisation, l'unique courroie 300 est remplacée par deux courroies distinctes montées sur des cylindres fixés aux parties inférieure et supérieure de l'accotoir, ces deux courroies pouvant être éventuellement crantées.According to a first variant (not shown here) of the second embodiment, the single belt 300 is replaced by two separate belts mounted on cylinders attached to the lower and upper armrest, these two belts possibly being serrated.

Selon une seconde variante (non représentée ici) du deuxième mode de réalisation, on remplace la courroie unique par un rideau roulant.According to a second variant (not shown here) of the second embodiment, the single belt is replaced by a rolling shutter.

Les figures 9 et 10 représentent un troisième mode de réalisation des moyens de déplacement 23.The Figures 9 and 10 represent a third embodiment of the displacement means 23.

Dans leur troisième mode de réalisation, les moyens de déplacement se présentent sous la forme d'un écrou 402 monté sur une vis sans fin 404 actionnée par un moteur 406 qui est fixé à la partie inférieure 408 de l'accotoir 14, la vis sans fin étant bloquée en translation.In their third embodiment, the displacement means are in the form of a nut 402 mounted on a worm 404 actuated by a motor 406 which is fixed to the lower portion 408 of the armrest 14, the screw without end being blocked in translation.

L'écrou 402 est fixé à un bras 410 transversal à la direction longitudinale de l'accotoir 14 et guidé en translation selon la direction longitudinale de l'accotoir par le biais de montants 412, 414 qui s'étendent eux-mêmes selon la direction longitudinale de l'accotoir 14, comme cela est bien visible sur les figures 9 et 10.The nut 402 is attached to an arm 410 transverse to the longitudinal direction of the armrest 14 and guided in translation in the direction longitudinal armrest by means of amounts 412, 414 which themselves extend in the longitudinal direction of the armrest 14, as is clearly visible on the Figures 9 and 10 .

On comprend que lorsqu'on actionne le moteur 406, la vis sans fin 404 tourne autour de son axe, déplaçant l'écrou 402 et, partant, le bras 410 est déplacé selon la direction longitudinale de l'accotoir 14.It is understood that when the motor 406 is actuated, the endless screw 404 rotates about its axis, displacing the nut 402 and, consequently, the arm 410 is moved in the longitudinal direction of the armrest 14.

La figure 11 montre plus en détail le moteur 406, la vis sans fin 404 et l'écrou 402.The figure 11 shows in more detail the motor 406, the worm 404 and the nut 402.

Dans les trois modes de réalisation qui viennent d'être décrits, l'accotoir 14 est préférentiellement pourvu de deux fentes longitudinales parallèle 28 permettant le passage des tiges 30 qui assurent la connexion entre la latte d'extrémité 26 et, en fonction du mode de réalisation, les bras 306, 410 ou le support 213.In the three embodiments that have just been described, the armrest 14 is preferably provided with two parallel longitudinal slots 28 allowing the passage of the rods 30 which provide the connection between the end lath 26 and, depending on the mode of operation. embodiment, the arms 306, 410 or the support 213.

Ces trois modes de réalisation des moyens de déplacement sont donnés à titre d'exemples et ne sauraient constituer une limitation pour la présente invention.These three embodiments of the displacement means are given by way of example and can not constitute a limitation for the present invention.
