The mattress support frame has three parts (3, 4, 5) which are joined together by transversal axles (6, 7). Pairs of levers (9, 10) join the ends of the axles and are articulated on an axle (8) on the base (2') of the frame. A telescopic bar (12) is fixed between the articulation (11) of one pair of levers (9, 9') and the base of the frame. It has a spring (13) round it which holds the bed in position. One branch (10') of the other pair of levers is telescopic.

Description

L'objet de la presente demande de Brevet d'Invention est constitué par un "LIT ARTICULE BASCULANT", dont la structure présente clairement differenciés un bâti de support, un bâti sommier, divisé à son tour en trois secteurs reliés entre eux d'une manière articulée par rapport à la carcasse de support par une série d'axes transversaux rattachés entre eux par deux paires de jeux de leviers, et un mécanisme de blocage pour la fixation de l'ensemble dans la position voulue. Tous ces éléments essentiels sont reliés entre eux de sorte que, une fois le mécanisme de blocage est libéré par le propre usager, la basculation de l'ensemble peut être provoquée et contrôlée par lui-même, en s'appuyant sur le lit et sans aide extérieure, au moyen de la pression exercée avec sa tête et ses épaules sur le tronçon chevet du sommier, et par le poids de ses jambes sur le tronçon opposé, en immobilisant à nouveau l'ensemble dans la position voulue en actionnant le mécanisme de blocage.The subject of the present patent application is constituted by a "TILT ARTICULATED BED", the structure of which clearly differentiates a support frame, a box frame, in turn divided into three sectors connected to one another. articulated with respect to the support frame by a series of transverse axes connected together by two pairs of sets of levers, and a locking mechanism for fixing the assembly in the desired position. All these essential elements are interconnected so that, once the locking mechanism is released by the user, the tilting of the assembly can be caused and controlled by itself, by leaning on the bed and without external aid, by means of the pressure exerted with his head and shoulders on the bedside section of the bed base, and by the weight of his legs on the opposite section, again immobilizing the assembly in the desired position by actuating the mechanism blocking.

Jusqu'à présent on connaît des lits articulés dans lesquels la position du chevet et de la zone des jambes est réglée séparément au moyen des mécanismes correspondants, indépendants entre eux, qui consistent essentiellement dans une série de bielles et d'une vis sans fin, actionnée par une manivelle, qui dans les deux cas, est maniée avec un certain effort par une personne située hors du lit, le tronçon central étant immobile, correspondant à la région abdominale de l'usager.Up to now, articulated beds are known in which the position of the bedside and the leg area is adjusted separately by means of the corresponding mechanisms, independent of each other, which essentially consist of a series of connecting rods and of an endless screw, actuated by a crank, which in both cases is handled with a certain effort by a person situated outside the bed, the central section being immobile, corresponding to the abdominal region of the user.

On connaît également des lits articulés dans lesquels la position ou l'inclinaison des divers secteurs est contrôlée au moyen d'un système hydraulique, actionné par l'équipement servomoteur correspondant; cette réalisation considérablement complexe suppose dans la pratique un coût de production élevé et requiert en plus un service d'entretien adéquat..There are also known articulated beds in which the position or the inclination of the various sectors is controlled by means of a hydraulic system, actuated by the corresponding servomotor equipment; this considerably complex realization implies in practice a high production cost and also requires an adequate maintenance service.

Les inconvénients signalés des mécanismes connus jusqu'à présent, ne se produisent pas dans le lit articulé basculant faisant l'objet de ce Brevet d'Invention, dans lequel l'usager lui-même, sans se déplacer et avec la simple pression et le poids de son corps, peut contrôler et modifier, sans brusquerie, l'inclinaison des trois tronçons du sommier, correspondants au chevet, à la zone intermédiaire et à la zone de repos des extrémités inférieures.The reported drawbacks of the mechanisms known up to now do not occur in the tilting articulated bed which is the subject of this Patent for Invention, in which the user himself, without moving and with the simple pressure and the weight of his body, can control and modify, without abruptness, the inclination of the three sections of the box spring, corresponding to the bedside, the intermediate zone and the rest zone lower extremities.

La carcasse du sommier est complétée avec les lames transversales correspondantes, les mailles métalliques ou jalousie pour l'appui du matelas correspondant, dans la version lit proprement dit, ou bien elle est complétée avec des housses de toile ou d'un autre matériel adéquat, ou avec des plaques ou des grilles, qui permettent l'utilisation de cette structure comme chaise longue pour le jardin, la terrasse, le solarium, ou même comme civière pour les salles de soins, les cabinets d'esthétique et d'autres.The carcass of the box spring is completed with the corresponding transverse blades, the metal mesh or louver for the support of the corresponding mattress, in the version bed proper, or it is completed with covers of canvas or other suitable material, or with plates or grids, which allow the use of this structure as a lounge chair for the garden, the terrace, the solarium, or even as a stretcher for treatment rooms, cosmetic offices and others.

Un autre objet de l'invention selon le Brevet d'Invention n° 9000883 du même titulaire, c'est que le lit peut être plié facilement, au moyen d'opérations simples, jusqu'à l'obtention d'une réduction maximum du volume, ce qui faciliterait son stockage et son transport, l'assemblage étant également obtenu au moyen d'opérations simples.Another object of the invention according to the Patent of invention n ° 9000883 of the same holder, is that the bed can be folded easily, by means of simple operations, until obtaining a maximum reduction of the volume, which would facilitate its storage and transport, the assembly also being obtained by means of simple operations.

Le lit de l'invention se caractérise par le fait que le panneau extrême du sommier est dirigé vers le côté du pied du lit, est relié avec le bâti au moyen de deux bielles, l'une antérieure et l'autre postérieure, articulées par leurs extrémités à ce panneau et au bâti, selon les axes perpendiculaires à l'axe longitudinal du lit, tandis que le panneau extrême du sommier qui est dirigé vers le chevet est articulé au bâti selon un axe transversal et il est en outre relié à ce bâti au moyen d'une bielle qui est articulée par son extrémité supérieure au panneau et qui est connectée au bâti avec capacité de glissement à travers un dispositif de freinage.The bed of the invention is characterized in that the end panel of the bed base is directed towards the side of the foot of the bed, is connected with the frame by means of two connecting rods, one anterior and the other posterior, articulated by their ends to this panel and to the frame, along the axes perpendicular to the longitudinal axis of the bed, while the end panel of the mattress which is directed towards the bedside is articulated to the frame along a transverse axis and it is further connected to this frame by means of a connecting rod which is articulated by its upper end to the panel and which is connected to the frame with ability to slide through a braking device.

La bielle antérieure qui relie le panneau extrême du côté du pied avec le bâti a une longueur supérieure à la distance entre l'axe d'articulation de cette bielle au bâti et le panneau, quand ce panneau est en position horizontale. L'axe d'articulation entre cette bielle et le panneau est déplacé par rapport à l'axe d'articulation de cette bielle avec le bâti, vers le côté transversal adjacent du sommier quand ce sommier est en position horizontale et vers le côté contraire quand il adopte la position de pliage maximum. En outre, cette bielle est poussée constamment vers la première position citée au moyen d'un ressort.The front connecting rod which connects the end panel on the side of the foot with the frame has a length greater than the distance between the axis of articulation of this connecting rod to the frame and the panel, when this panel is in a horizontal position. The axis of articulation between this connecting rod and the panel is moved relative to the axis of articulation of this connecting rod with the frame, towards the adjacent transverse side of the bed base when this bed base is in horizontal position and towards the opposite side when it adopts the maximum folding position. In addition, this connecting rod is constantly pushed towards the first cited position by means of a spring.

La bielle postérieure qui relie le panneau extrême avec le bâti a une longueur égale à la distance entre l'axe d'articulation de cette bielle au bâti et le panneau, quand ce panneau est en position horizontale.The rear connecting rod which connects the end panel with the frame has a length equal to the distance between the axis of articulation of this connecting rod to the frame and the panel, when this panel is in a horizontal position.

Les deux bielles qui relient le panneau externe dirigé vers le pied avec le bâti sont composées, chacune, de deux barres parallèles unies par deux traverses, dont les barres sont situées en sens perpendiculaire à l'axe longitudinal du lit et sont connectées par leurs extrémités avec capacité de rotation, l'une d'elles au bâti et l'autre au panneau, au moyen de douilles solidaires à ce bâti et aux panneaux.The two connecting rods which connect the external panel directed towards the foot with the frame are each composed of two parallel bars united by two crosspieces, the bars of which are located in a direction perpendicular to the longitudinal axis of the bed and are connected by their ends. with rotational capacity, one of them to the frame and the other to the panel, by means of sockets integral with this frame and with the panels.

La bielle postérieure qui relie le panneau extrême avec le bâti est articulée à ce panneau dans un point proche au point d'articulation entre ce panneau et le panneau intermédiaire.The rear connecting rod which connects the end panel with the frame is articulated to this panel at a point close to the point of articulation between this panel and the intermediate panel.

Le dispositif de freinage commenté auparavant est composé de mâchoires entre lesquelles passent les bielles du panneau extrême dirigé vers le chevet. Ces mâchoires peuvent être rapprochées ou séparées, en bloquant ou en libérant les bielles, au moyen d'un levier d'actionnement.The braking device commented on above is composed of jaws between which pass the connecting rods of the end panel directed towards the bedside. These jaws can be brought together or separated, by blocking or releasing the connecting rods, by means of an actuating lever.

Avec la constitution commentée, la personne qui occupe le lit peut, au moyen d'une légère pression, régler la position du sommier, entre une situation horizontale et plate et une autre partiellement pliée, dans laquelle le panneau extrême dirigé vers le chevet forme un certain angle avec le panneau intermédiaire, tandis que l'autre panneau extrême reste en position horizontale, mais déplacé longitudinalement vers le centre du lit.With the commented constitution, the person occupying the bed can, by means of a light pressure, adjust the position of the box spring, between a horizontal and flat situation and another partially folded, in which the extreme panel directed towards the bedside certain angle with the intermediate panel, while the other extreme panel remains in a horizontal position, but moved longitudinally towards the center of the bed.

Le lit de l'invention n'a pas de broches ni d'amortisseurs qui renchérissent et compliquent sa construction.The bed of the invention has no pins or shock absorbers which increase the cost and complicate its construction.

D'après une autre caractéristique de l'invention, le bâti du lit est pliable, de sorte qu'il permet même le pliage postérieur du sommier, en permettant d'obtenir un volume minimum pour le stockage et le transport. On obtient le pliage et le dépliage total du lit au moyen d'opérations simples.According to another characteristic of the invention, the bed frame is foldable, so that it even allows posterior folding of the bed base, making it possible to obtain a minimum volume for storage and transport. The complete folding and unfolding of the bed is obtained by simple operations.

En accord avec l'invention, le bâti du lit est constitué par deux carcasses indépendantes pliables, chacune d'elles étant située sous l'un des panneaux extrêmes du sommier. Ces deux carcasses pliables sont reliées au moyen d'une carcasse plate intermédiaire démontable.In accordance with the invention, the bed frame consists of two independent foldable carcasses, each of which is located under one of the end panels of the bed base. These two foldable carcasses are connected by means of a removable intermediate flat carcass.

Dans les dessins ci-joints qui font partie intégrante du présent mémoire descriptif, on a représenté, d'une manière simplifiée, à titre d'exemple illustratif, mais non limitatif, une réalisation de ce lit articulé basculant, qui comprend deux versions différentes du dispositif de blocage.In the accompanying drawings which form an integral part of this specification, there is shown, in a simplified manner, by way of illustrative, but not limiting example, an embodiment of this articulated tilting bed, which comprises two different versions of the blocking device.

Le lit se compose d'une base de soutien formée par deux bâtis symétriques qui présentent les pieds correspondants (1), (1′), dont les plus hauts sont ceux qui correspondent au chevet, ces pieds se prolongant, sans solution de continuité avec les plans horizontaux correspondants (2), (2′), dont la hauteur et la longueur sont inégales, reliés entre eux par un tronçon central incliné (2˝); le plan (2) correspondant au chevet du lit est plus haut et moins étendu que le tronçon (2′), correspondant aux extrémités inférieures. Le bâti sommier est constitué par un cadre tubulaire, ayant la section, les dimensions et la configuration adéquates, divisé en trois secteurs clairement différenciés et articulés: le tronçon (3) correspond à la zone de repos de la tête et du thorax de l'usager, le tronçon intermédiaire (4) correspond à la région abdominale et aux cuisses et le tronçon inférieur (5), correspond à la zone de repos de la moitié inférieure des jambes, à partir des genoux; pour des raisons de simplicité nous dénommerons le tronçon (3), comme chevet du sommier et le tronçon (5) comme extrémité inférieure du sommier. L'union articulée entre le chevet du sommier (3) et la zone intermédiaire (4) est réalisée au moyen de l'axe correspondant (6) et l'union articulée entre la zone intermédiaire (4) et la zone inférieure (5) du bâti du sommier est réalisée au moyen de l'axe correspondant (7). A leur tour, ces centres d'articulation ou extrémités des axes (6) et (7), sont rattachés d'une manière articulée entre eux par les jeux de leviers correspondants dont l'axe d'articulation ou point de compas (8) est monté fixe sur le tronçon (2′) de la base de soutien du lit.The bed consists of a support base formed by two symmetrical frames which present the corresponding feet (1), (1 ′), the tallest of which are those which correspond to the bedside, these feet extending, without a solution of continuity with the corresponding horizontal planes (2), (2 ′), the height and length of which are unequal, connected to one another by an inclined central section (2˝); the plane (2) corresponding to the bedside is higher and less extensive than the section (2 ′), corresponding to the lower ends. The base frame is constituted by a tubular frame, having the adequate section, dimensions and configuration, divided into three clearly differentiated and articulated sectors: the section (3) corresponds to the zone of rest of the head and the thorax of the user, the intermediate section (4) corresponds to the abdominal region and the thighs and the lower section (5), corresponds to the rest zone of the lower half of the legs, starting from the knees; for reasons of simplicity we will refer to the section (3) as the bedside table and the section (5) as the lower end of the bed base. The articulated union between the bedside of the box spring (3) and the intermediate zone (4) is produced by means of the corresponding axis (6) and the articulated union between the intermediate zone (4) and the lower zone (5) of the bed base frame is produced by means of the corresponding axis (7). In turn, these articulation centers or ends of the axes (6) and (7), are attached in an articulated manner to each other by the corresponding sets of levers, the hinge pin or compass point (8) is fixedly mounted on the section (2 ′) of the support base of the bed.

Les extrémités des branches (9) et (10) de chacune de ces paires de leviers sont unies respectivement au point d'articulation (7), entre le tronçon inférieur (5) du sommier et le tronçon moyen (4) et au point d'articulation (6) entre le dit tronçon moyen (4) et le chevet (3) du sommier. La branche (9) de chaque jeu de leviers, est formée à son tour par deux bras (9), (9′), articulés entre eux dans le point (11), duquel part à son tour une barre télescopique (12) dotée d'un ressort d'expansion (13), dont la barre (12) est fixée par son autre extrémité au tronçon inférieur (2') de la carcasse de soutien du lit. La branche (10) du jeu de leviers est également formée par deux bras (10), (10′) unis d'une manière articulée entre eux dans le point (14), le bras (10′) étant constitué par une barre télescopique. Dans le point de compas (8) est accouplé un triangle de tôle (15) dont la base inférieure est soudée à la barre télescopique (10′) et dont le sommet supérieur est soudé à une tige transversale (16) qui agit comme pousseur de la branche (9), (9′) du jeu de leviers.The ends of the branches (9) and (10) of each of these pairs of levers are united respectively at the point of articulation (7), between the lower section (5) of the bed base and the middle section (4) and at point d 'joint (6) between said middle section (4) and the bedside (3) of the bed base. The branch (9) of each set of levers, is in turn formed by two arms (9), (9 ′), hinged together in point (11), from which a telescopic bar (12) in turn has an expansion spring (13), the bar (12) of which is fixed by its other end to the lower section (2 ') of the bed support carcass. The branch (10) of the set of levers is also formed by two arms (10), (10 ′) joined in an articulated manner to each other in point (14), the arm (10 ′) being constituted by a telescopic bar . In the compass point (8) is coupled a sheet metal triangle (15) whose lower base is welded to the telescopic bar (10 ′) and whose upper top is welded to a transverse rod (16) which acts as a pusher the branch (9), (9 ′) of the set of levers.

Ce jeu de leviers permet que l'usager lui-même, en pressant avec sa tête et ses épaules, sans abandonner le lit, sur le chevet (3), du bâti du sommier qui s'appuie sur un axe (17) prévu dans la carcasse de base, l'ensemble de la carcasse du sommier bascule proportionnellement à la pression exercée, en pouvant fixer l'ensemble dans la position voulue au moyen d'un système de blocage, que l'on décrira postérieurement.This set of levers allows the user himself, by pressing with his head and his shoulders, without abandoning the bed, on the bedside (3), of the bed base frame which rests on an axis (17) provided in the basic carcass, the entire carcass of the box spring rocks in proportion to the pressure exerted, being able to fix the assembly in the desired position by means of a blocking system, which will be described later.

La barre télescopique (12), en vertu du ressort d'expansion (13) auquel elle sert de guide, presse normalement sur le point d'articulation (11) de la branche (9), (9′), reliée au point d'articulation (7), entre le tronçon inférieur (5) du sommier et le tronçon intermédiaire (4), et pour cette raison ce tronçon inférieur (5) a tendance à occuper normalement une même position.The telescopic bar (12), by virtue of the expansion spring (13) to which it serves as a guide, normally presses on the articulation point (11) of the branch (9), (9 ′), connected to the point d hinge (7) between the lower section (5) of the bed base and the intermediate section (4), and for this this lower section (5) tends to normally occupy the same position.

On a prévu de pouvoir accoupler à ce lit articulé basculant un mécanisme de frein, représenté dans la figure n° 4, qui peut être actionné par l'usager lui-même, sans qu'il se déplace du lit, au moyen du levier (18) d'une excentrique (19) à deux pentes reliée à une barre (20) constituée par un double élément tubulaire concentrique dont le tube intérieur (20′) est soudé par l'une de ses extrémités à l'élément fixe de l'excentrique (19), tandis que l'élément extérieur (20) sectionné, présente accouplée dans l'extrémité opposée un goujon doté d'un écrou de réglage (21), et il est soudé à la carcasse de soutien du lit, dans son tronçon incliné (2˝); ces éléments cylindriques concentriques (20), (20′), présentent des paires d'orifices débouchants (22), (22′), vis-à-vis et dotés de tolérance, qui sont traversés par les tiges correspondantes (23), (23′), soudées à l'axe (6) d'articulation entre le chevet (3) du sommier et la zone moyenne (4), de telle manière que quand on actionne le levier de l'excentrique en lui imprimant un tour de 90° l'élément tubulaire interne (20′) et l'élément tubulaire externe (20) se déplacent axialement dans le sens contraire, et les paires respectives d'orifices vis-à-vis (22), (22′) sont déplacés partiellement en exerçant une action de mâchoire sur les tiges (23), (23′) en fixant ainsi la position du tronçon chevet (3) du bâti du sommier.Provision has been made to be able to couple to this tilting articulated bed a brake mechanism, represented in FIG. 4, which can be actuated by the user himself, without moving from the bed, by means of the lever ( 18) an eccentric (19) with two slopes connected to a bar (20) constituted by a double concentric tubular element whose inner tube (20 ′) is welded by one of its ends to the fixed element of the eccentric (19), while the external element (20) sectioned, has coupled in the opposite end a stud provided with an adjusting nut (21), and it is welded to the support frame of the bed, in its inclined section (2˝); these concentric cylindrical elements (20), (20 ′), have pairs of through orifices (22), (22 ′), opposite and provided with tolerance, which are crossed by the corresponding rods (23), (23 ′), welded to the axis (6) of articulation between the bedside (3) of the box spring and the middle zone (4), so that when the lever of the eccentric is actuated by giving it a turn by 90 ° the internal tubular element (20 ′) and the external tubular element (20) move axially in the opposite direction, and the respective pairs of orifices opposite (22), (22 ′) are partially displaced by exerting a jaw action on the rods (23), (23 ′) thereby fixing the position of the bedside section (3) of the bed base frame.

Dans la réalisation représentée dans la figure n° 6, on a prévu un autre mécanisme de blocage ou de frein pour ce lit articulé basculant, lequel mécanisme est accouplé à l'axe ou à la barre (17) d'articulation du tronçon chevet (3) du sommier, à l'angle de liaison entre (2) et le tronçon (2˝) de la base de soutien du lit.In the embodiment shown in FIG. 6, another locking or brake mechanism has been provided for this tilting articulated bed, which mechanism is coupled to the axis or to the bar (17) of articulation of the bedside section ( 3) of the bed base, at the connection angle between (2) and the section (2˝) of the support base of the bed.

Dans cette réalisation cet axe (17) est constitué par deux éléments cylindriques concentriques, dont l'élément extérieur (17) sectionné est fixé à travers des bagues soudées à la carcasse de base et au bâti (3) du sommier, et il présente dans l'une de ses extrémités un goujon et un écrou de réglage (24), tandis que l'extrémité opposée du cylindre intérieur (17′), est soudée à la moitié fixe (25′) d'une excentrique à deux pentes; dans ce dernier axe (17′) sont accouplées deux séries de disques de pression (26), dotés des bras correspondants unis alternativement à travers les goupilles correspondantes (27), (27′) à la carcasse de base et au cadre chevet (3) de la carcasse sommier, avec interposition des rondelles de compensation correspondantes; de cette manière quand on actionne de 90° le levier (29), relié à la moitié mobile (25) de l'excentrique, l'éIément cylindrique interne (17˝) et l'élément cylindrique externe (17′) se déplacent axialement dans le sens contraire en donnant lieu à la compression des blocs de disques et à l'immobilisation de tout le mécanisme.In this embodiment, this axis (17) consists of two concentric cylindrical elements, the external element (17) of which is sectioned is fixed through rings welded to the base carcass and to the frame (3) of the bed base, and it has in one of its ends a stud and an adjusting nut (24), while the opposite end of the inner cylinder (17 ′) is welded to the fixed half (25 ′) of an eccentric with two slopes ; in this latter axis (17 ′) are coupled two series of pressure discs (26), provided with corresponding arms alternately joined through the corresponding pins (27), (27 ′) to the base frame and to the bedside frame (3 ) the box spring carcass, with the interposition of the corresponding compensation washers; in this way when the lever (29) is actuated by 90 °, connected to the movable half (25) of the eccentric, the internal cylindrical element (17˝) and the external cylindrical element (17 ′) move axially in the opposite direction, giving rise to the compression of the disc blocks and the immobilization of the entire mechanism.

La carcasse du sommier est complétée avec les lames transversales correspondantes, les mailles métalliques, la jalousie ou les panneaux pour l'appui du matelas, dont les éléments sont accouplés au bâti du sommier avec n'importe quel moyen conventionnel adéquat.The carcass of the box spring is completed with the corresponding transverse blades, the metal meshes, the jalousie or the panels for the support of the mattress, the elements of which are coupled to the bed frame with any conventional means suitable.

Dans une autre réalisation on a prévu que le bâti du sommier soit complété avec des housses de toile ou d'un autre matériel adéquat ou des bandes, des grilles ou des panneaux ou des éléments adéquats, qui ne requièrent pas nécessairement l'utilisation d'un matelas complémentaire et qui permettent l'utilisation de cette structure de lit articulé basculant comme chaise longue pour le jardin, la terrasse, le solarium, etc., ou même comme civière pour les salles de soins, lit de massage, cabinets d'esthétique et autres.In another embodiment, provision has been made for the bed base frame to be completed with covers of canvas or of other suitable material or of bands, grids or panels or of suitable elements, which do not necessarily require the use of an additional mattress and which allow the use of this articulated tilting bed structure as a lounge chair for the garden, the terrace, the solarium, etc., or even as a stretcher for treatment rooms, massage bed, beauty cabinets and others.

Le lit représenté dans les dessins comprend, comme on peut le voir dans la figure n° 7, un bâti support et un sommier articulé. Le bâti est composé de deux carcasses pliables et indépendantes, avec les numéros de référence (29) et (30), qui sont unies entre elles au moyen d'une carcasse plate intermédiaire (31). Quant au sommier, il est subdivisé en trois panneaux avec les numéros de référence (32), (33) et (34), qui sont articulés consécutivement entre eux à travers leurs bords adjacents, l'articulation entre les panneaux (32) et (33) portant le numéro de référence (35).The bed shown in the drawings comprises, as can be seen in Figure No. 7, a support frame and an articulated base. The frame is composed of two foldable and independent carcasses, with the reference numbers (29) and (30), which are joined together by means of an intermediate flat carcass (31). As for the box spring, it is subdivided into three panels with the reference numbers (32), (33) and (34), which are hinged together consecutively through their adjacent edges, the articulation between the panels (32) and (33) bearing the reference number (35).

Le panneau extrême (34) du sommier, dirigé vers le côté du pied du lit, est en rapport avec le bâti au moyen d'une bielle antérieure (37), composée par deux barres parallèles (38) et (39) unies entre elles au moyen de traverses (40), et au moyen d'une bielle postérieure (41) formée par deux barres parallèles (42) et (43) unies au moyen de traverses (44). La barre (38) peut tourner librement par ses extrémités par rapport au panneau (34), tandis que la barre (39) peut tourner librement par ses extrémités par rapport à la carcasse (30) du bâti. De la même manière la barre (42) peut tourner librement par ses extrémités par rapport au panneau (34), tandis que la barre (43) peut tourner librement par ses extrémités par rapport à la carcasse (30) du bâti.The end panel (34) of the bed base, directed towards the side of the foot of the bed, is in relation to the frame by means of an anterior connecting rod (37), composed by two parallel bars (38) and (39) joined together by means of crosspieces (40), and by means of a rear link (41) formed by two parallel bars (42) and (43) united by means of crosspieces (44). The bar (38) can rotate freely at its ends relative to the panel (34), while the bar (39) can rotate freely at its ends relative to the frame (30). In the same way the bar (42) can rotate freely at its ends relative to the panel (34), while the bar (43) can rotate freely at its ends relative to the frame (30) of the frame.

Le panneau extrême (32), qui est dirigé vers le côté du chevet du lit, est articulé aux carcasses (29) et (30) du bâti au moyen d'axes alignés (45) qui sont perpendiculaires à l'axe longitudinal du lit. En outre, ce panneau (32) est en rapport avec les carcasses (29) et (30) du bâti au moyen d'une bielle (46) qui est constituée par une barre (47) qui tourne librement à travers ses extrémités par rapport au panneau (32), une barre fixe (48), qui est unie à travers ses extrémités aux carcasses (29) et (30) du bâti, et par deux bras (49) qui sont solidarisés radialement à la barre (47) et pouvant se déplacer longitudinalement entre les paires de mâchoires (50) montées avec capacité de rotation et de glissement libre dans la barre fixe (48).The end panel (32), which is directed towards the side of the bedside, is articulated to the carcasses (29) and (30) of the frame by means of aligned axes (45) which are perpendicular to the longitudinal axis of the bed . In addition, this panel (32) is in relation to the carcasses (29) and (30) of the frame by means of a connecting rod (46) which is constituted by a bar (47) which rotates freely through its ends relative to to the panel (32), a fixed bar (48), which is joined through its ends to the carcasses (29) and (30) of the frame, and by two arms (49) which are joined radially to the bar (47) and able to move longitudinally between the pairs of jaws (50) mounted with the ability to rotate and slide freely in the fixed bar (48).

Comme on peut l'apprécier mieux dans les figures n° 8 et 9, chacune des mâchoires de chaque paire de mâchoires (50) est fixée à une douille (51) et (52) pouvant tourner et se déplacer librement sur la barre (48). Entre les deux douilles internes (51) sont montées deux autres douilles (53), qui peuvent également se déplacer et tourner librement dans la barre (48). Ces douilles (53) ont des oreilles radiales auxquelles on connecte un jeu de trois leviers (54), (55) et (56) qui sont articulés consécutivement entre eux au moyen de rivets ou d'éléments de rotation (57) et (58). A son tour, le levier (54) est relié à travers son extrémité, au moyen d'une articulation (59), à l'oreille radiale de la douille adjacente (53), tandis que le levier (55) est connecté à travers un point intermédiaire, au moyen de l'articulation (50), à l'oreille radiale de l'autre douille (53). En outre, le levier (56) est articulé, à travers un point intermédiaire (51) à une deuxième oreille de la douille adjacente (53), ce levier se prolongeant (56) vers l'extérieur du lit, pour définir un levier d'actionnement (62).As can be better appreciated in Figures 8 and 9, each of the jaws of each pair of jaws (50) is fixed to a socket (51) and (52) which can rotate and move freely on the bar (48 ). Between the two internal sockets (51) are mounted two other sockets (53), which can also move and rotate freely in the bar (48). These sockets (53) have radial lugs to which a set of three levers (54), (55) and (56) are connected which are hinged consecutively to each other by means of rivets or of rotation elements (57) and (58 ). In turn, the lever (54) is connected through its end, by means of a joint (59), to the radial ear of the adjacent bushing (53), while the lever (55) is connected through an intermediate point, by means of the articulation (50), at the radial ear of the other sleeve (53). In addition, the lever (56) is articulated, through an intermediate point (51) to a second ear of the adjacent socket (53), this lever extending (56) towards the outside of the bed, to define a lever d actuation (62).

Dans la position représentée dans la figure n° 9, les douilles (53) sont déplacées vers l'extérieur, en comprimant les mâchoires (50) entre les douilles (51) et (52) qui pressent contre les bras (49) en empêchant leur déplacement.In the position shown in Figure 9, the sleeves (53) are moved outward, compressing the jaws (50) between the sleeves (51) and (52) which press against the arms (49) preventing their displacement.

Quand on déplace le levier (62) à la position de référence n° (62a), les leviers (54) et (55) passent à occuper la position représentée au moyen d'une seule ligne, en déplaçant les douilles (53) vers le centre de la barre (48) en se rapprochant entre eux, et en ne pressant plus les douilles (51) et (52), et de cette façon les mâchoires (50) ne sont plus pressées entre elles, en libérant les bras (49) qui peuvent alors se déplacer axialement par rapport à ces mâchoires.When the lever (62) is moved to the reference position no. (62a), the levers (54) and (55) move to occupy the position shown by means of a single line, by moving the sockets (53) towards the center of the bar (48) approaching them, and no longer pressing the sockets (51) and (52), and in this way the jaws (50) are no longer pressed together, freeing the arms ( 49) which can then move axially relative to these jaws.

Dans la figure n° 8 on représente le sommier en position de pliage maximum, en pliage intermédiaire et en position horizontale. La figure n° 9 correspond au lit avec le sommier en position horizontale.In figure n ° 8 the box spring is shown in the maximum folding position, in intermediate folding and in the horizontal position. Figure 9 corresponds to the bed with the box spring in a horizontal position.

En partant de la position de pliage maximum de la figure n° 8, pour obtenir la position horizontale du sommier il sera suffisant d'agir sur le levier (62) pour libérer les mâchoires (60) de la manière déjà décrite. Ensuite, en exerçant une légère pression avec le dos sur le panneau (32) extrême du sommier, on réussit à ce que ce dernier tourne vers la position horizontale, en même temps qu'on obtient le déplacement et la rotation du panneau intermédiaire (33) et le déplacement longitudinal du panneau extrême (34), jusqu'à atteindre la position horizontale complète, moment où on agit à nouveau sur le levier (62) pour le blocage des bras (4). Dans la position horizontale du sommier, les panneaux occupent les positions (32a), (33a) et (34a) et les traverses des bielles (37) et (41) les positions (50a) et (54a), montrées dans la figure n° 8.Starting from the maximum folding position in Figure 8, to obtain the horizontal position of the bed base it will be sufficient to act on the lever (62) to release the jaws (60) in the manner already described. Then, by exerting a light pressure with the back on the panel (32) extreme of the bed base, one succeeds in making it turn towards the horizontal position, at the same time as the displacement and rotation of the intermediate panel (33) and the longitudinal displacement of the extreme panel (34) are obtained, until the complete horizontal position is reached, when action is again taken on the lever (62) for locking the arms (4). In the horizontal position of the bed base, the panels occupy the positions (32a), (33a) and (34a) and the crosspieces of the connecting rods (37) and (41) the positions (50a) and (54a), shown in FIG. ° 8.

La bielle (46), avec l'ensemble de moyens de freinage, pourraît être située sous l'axe d'articulation (45) entre le panneau (32) et le bâti du lit. Dans la figure n° 9 avec la référence (63) on indique les tablettes qui sont fixées aux longerons des différents panneaux du sommier.The connecting rod (46), with the set of braking means, could be located under the hinge pin (45) between the panel (32) and the bed frame. In figure n ° 9 with the reference (63) the shelves are indicated which are fixed to the side members of the various panels of the bed base.

Comme on peut le constater dans la figure n° 8, la longueur des barres (40), qui définissent la longueur de la bielle (37), est supérieure à la distance entre le point d'articulation (39) de cette bielle avec le bâti et le panneau (34) du sommier, quand ce sommier est en position horizontale. Quant aux traverses (44) qui définissent la longueur de la came (41) elle est égale à la distance entre le point d'articulation (43) entre cette came et le bâti et le panneau (33) du sommier quand celui-ci est en position horizontale. Finalement, les bras (49) qui définissent la longueur de la bielle (46) ont une longueur variable, entre le point d'articulation (47) et les mâchoires (50), quand on plie ou on rabat les panneaux du lit.As can be seen in Figure 8, the length of the bars (40), which define the length of the rod (37), is greater than the distance between the point of articulation (39) of this rod with the frame and the panel (34) of the bed base, when this bed base is in a horizontal position. As for the crosspieces (44) which define the length of the cam (41) it is equal to the distance between the articulation point (43) between this cam and the frame and the panel (33) of the bed base when the latter is in horizontal position. Finally, the arms (49) which define the length of the connecting rod (46) have a variable length, between the point of articulation (47) and the jaws (50), when the panels of the bed are folded or folded down.

La bielle (37) peut être constamment poussée vers la position (40a) qui correspond à la position horizontale du sommier, au moyen d'un ressort.The connecting rod (37) can be constantly pushed towards the position (40a) which corresponds to the horizontal position of the bed base, by means of a spring.

Comme on l'a indiqué antérieurement, le bâti du lit est composé de carcasses indépendantes (29) et (30), dont la première est située sous le panneau extrême (32) du sommier, tandis que la deuxième est située sous le panneau extrême (34). Chacune des carcasses (29) et (30) est constituée par autant de cadres supérieurs (65) et (66) horizontaux en forme de C, qui sont disposés transversalement, vis-à-vis. A chacune des branches latérales de ces cadres est articulée une structure inférieure (67) d'appui, qui adopte une forme de cadre triangulaire, dans l'exemple représenté dans les dessins, et qui est parachevée inférieurement par un pied (68). Le cadre triangulaire est articulé à la branche latérale correspondante du cadre (65) ou (66) selon un axe (69) parallèle à l'axe longitudinal du lit.As indicated previously, the bed frame is composed of independent carcasses (29) and (30), the first of which is located under the end panel (32) of the bed base, while the second is located under the end panel (34). Each of the carcasses (29) and (30) consists of as many upper frames (65) and (66) horizontal C-shaped, which are arranged transversely, vis-à-vis. At each of the lateral branches of these frames is articulated a lower support structure (67), which adopts a triangular frame shape, in the example shown in the drawings, and which is completed below by a foot (68). The triangular frame is articulated to the corresponding lateral branch of the frame (65) or (66) along an axis (69) parallel to the longitudinal axis of the bed.

La carcasse plate intermédiaire (31) est composée par deux barres longitudinales (70) qui s'unissent à des barres transversales (71) pouvant être fixées aux carcasses (67) au moyen de connecteurs facilement démontables.The intermediate flat carcass (31) is composed of two longitudinal bars (70) which join to transverse bars (71) which can be fixed to the carcasses (67) by means of easily removable connectors.

Avec la constitution commentée, quand on désire plier le lit, on démonte la carcasse plate (70) et on rabat les carcasses (67) vers les cadres (65) et (66). Dans cette position on peut plier, en outre, les panneaux entre eux (32), (33) et (34) qui forment le sommier du lit, en occupant alors un volume extrêmement réduit. Pour l'assemblage du lit on procède de la manière inverse: on déplie les panneaux du sommier, ensuite les carcasses (67) et, finalement, on fixe la carcasse plate (70).With the commented constitution, when one wishes to fold the bed, the flat carcass (70) is dismantled and the carcases (67) are folded down towards the frames (65) and (66). In this position, the panels can be folded together (32), (33) and (34) which form the bed base, while occupying an extremely small volume. For the assembly of the bed we proceed in the opposite way: we unfold the box spring panels, then the carcasses (67) and, finally, we fix the flat carcass (70).

Ayant suffisamment décrit en quoi consiste la présente demande de Brevet en correspondance avec les plans ci-joints, on comprend qu'on pourra introduire dans celui-ci toutes les modifications de détail que l'on estimera convenables à condition qu'elles n'altèrent pas l'essence du Brevet qui est résumée dans les REVENDICATIONS suivantes.Having sufficiently described what this patent application consists of in correspondence with the attached plans, we understand that we will be able to introduce into it all the modifications of detail that we deem suitable provided they do not alter not the essence of the Patent which is summarized in the following CLAIMS.
