Une telle structure connue a pour inconvénients d'être relativement lourde, onéreuse et de ne pas se prêter à des cadences de production élevées.Such a known structure has the drawbacks of being relatively heavy, expensive and not amenable to high production rates.

GB-A-2 213 462 et US 3 680 494 A sont des structures de support avec une orientation de nid d'abeille spéciale. GB-A-2,213,462 and US 3 680 494 A are support structures with a special honeycomb orientation.

US 5 337 916 A est une boîte fabriquée à partir d'une plaque de base rectangulaire. US 5,337,916A is a box made from a rectangular base plate.

La présente invention a pour but d'éliminer les inconvénients ci-dessus en proposant une structure de sommier de literie peu coûteuse, légère et autorisant une cadence de production relativement élevée.The present invention aims to eliminate the above disadvantages by providing an inexpensive bed frame structure, lightweight and allowing a relatively high production rate.

A cet effet, la structure de sommier de literie à au moins deux longerons et deux traverses assemblés les uns aux autres, est caractérisée en ce que les longerons et les traverses du sommier sont réalisés en un matériau à base de carton comprenant une âme en nid d'abeille en carton rigide en flexion prise en sandwich entre deux feuilles de carton collées à l'âme.For this purpose, the bed frame structure with at least two longitudinal members and two crosspieces assembled to each other, is characterized in that the longitudinal members and the sleepers cross are made of a cardboard-based material comprising a nest core bee rigid cardboard bending sandwiched between two sheets of cardboard glued to the soul.

La structure de sommier comprend en outre au moins une plaque de couchage également en un matériau à base de carton, solidaire des longerons et des traverses du sommier, et comprenant une âme en nid d'abeille en carton rigide en flexion prise en sandwich entre deux feuilles de carton collées à l'âme et constituant les faces supérieure et inférieure de la plaque de couchage.The bed base structure further comprises at least one sleeping plate also made of a cardboard-based material, integral with the longitudinal members and cross members of the bed base, and comprising a honeycomb core made of stiff flexural cardboard sandwiched between two sheets of cardboard glued to the core and constituting the upper and lower faces of the sleeping plate.

Selon un second mode de réalisation, l'invention vise également une structure de sommier de literie caractérisée en ce qu'elle comprend au moins une plaque de couchage en un matériau à base de carton comprenant une âme en nid d'abeille en carton rigide en flexion prise en sandwich entre deux feuilles de carton collées à l'âme.According to a second embodiment, the invention also provides a bedding frame structure characterized in that it comprises at least one bedding plate made of a cardboard-based material comprising a honeycomb core made of rigid cardboard flexion sandwiched between two sheets of cardboard glued to the soul.

Selon ce mode de réalisation, la plaque de couchage est solidaire de longerons et de traverses du sommier réalisés en un matériau à base de carton comprenant une âme en nid d'abeille en carton rigide en flexion et prise en sandwich entre deux feuilles de carton collées à l'âme.According to this embodiment, the sleeping plate is secured to longitudinal members and sleepers of the bed base made of a cardboard-based material comprising a honeycomb core made of rigid cardboard flexion and sandwiched between two sheets of cardboard glued to the soul.

La structure de sommier peut comprendre deux ou plusieurs autres plaques de couchage superposées les unes sur les autres.The bed frame structure may include two or more other sleeping plates superimposed on each other.

Lorsqu'un dosseret de lit est associé à la structure de sommier, le dosseret est également en un matériau à base de carton comprenant une âme en nid d'abeille en carton rigide en flexion prise en sandwich entre deux feuilles de carton collées à l'âme constituant les faces avant et arrière du dosseret.When a backsplash is associated with the bed frame structure, the backsplash is also made of a cardboard-based material comprising a honeycomb core made of stiff flexboard cardboard sandwiched between two sheets of cardboard glued to the backboard. soul constituting the front and rear faces of the backsplash.

Avantageusement, les longerons et les traverses sont solidarisés les uns aux autres par agrafage et/ou collage et sont fixés par collage aux côtés ou sur une face de la plaque de couchage de manière à constituer un cadre de support faisant saillie de la face de la plaque de couchage.Advantageously, the longitudinal members and crosspieces are secured to each other by stapling and / or bonding and are fixed by gluing to the sides or on one face of the coating plate so as to constitute a support frame projecting from the face of the sleeping plate.

Chaque longeron et chaque traverse présente en section transversale une forme en trapèze rectangle dont le côté incliné est en regard du côté incliné conjugué correspondant de la plaque de couchage de manière que ces deux côtés inclinés soient en appui l'un contre l'autre en position de fixation du longeron ou de la traverse dont le côté constituant la petite base du trapèze rectangle est perpendiculaire à la plaque de couchage à cette position.Each spar and each cross member has in cross section a rectangular trapezoidal shape whose inclined side is opposite the corresponding conjugate inclined side of the coating plate so that the two inclined sides bear against each other in position fixing the spar or cross member whose side constituting the small base of the rectangle trapezium is perpendicular to the coating plate at this position.

Les extrémités des longerons et des traverses présentent des faces inclinées conjuguées de manière à venir en appui les unes sur les autres en position de fixation des longerons et traverses sur les côtés correspondants de la plaque de couchage.The ends of the longitudinal members and crosspieces have conjugate inclined faces so as to bear on each other in the attachment position of the longitudinal members and crosspieces on the corresponding sides of the coating plate.

Selon un second mode de réalisation préféré, chaque longeron et chaque traverse est en forme de parallélépipède rectangle et est relié à la plaque de couchage, à l'état avant confection du sommier, par une partie de feuille de carton souple appartenant à la même feuille de carton constituant la face de couchage de la plaque et la face correspondante du longeron et de la traverse de manière à permettre le rabattement des longerons et traverses sur la face de la plaque opposée à sa face de couchage pour former le cadre de support bordant la plaque de couchage.According to a second preferred embodiment, each spar and each cross member is in the form of a rectangular parallelepiped and is connected to the bedding plate, in the state before making the bed base, by a portion of flexible paperboard sheet belonging to the same sheet. of cardboard constituting the coating face of the plate and the corresponding face of the beam and the cross member so as to allow the folding of the longitudinal members and crosspieces on the face of the plate opposite its coating face to form the support frame bordering the sleeping plate.

La plaque de couchage, les longerons et les traverses ont une même épaisseur et les longerons et les traverses, à l'état avant confection du sommier, sont reliés parallèlement à la plaque de couchage par les parties souples de la feuille de carton à une distance de la plaque double de l'épaisseur de cette dernière, de façon qu'en position de fixation des longerons et des traverses sous la plaque après rabattement de ceux-ci, les côtés externes des longerons et traverses soient dans un même plan que les côtés externes de la plaque de couchage.The sleeping plate, the beams and the sleepers have the same thickness and the longitudinal members and sleepers, in the state before making the bed base, are connected parallel to the sleeping plate by the flexible parts of the sheet of cardboard at a distance of the double plate of the thickness of the latter, so that in the fixing position of the side members and sleepers under the plate after folding them, the outer sides of the side members and sleepers are in the same plane as the sides external of the sleeping plate.

Les traverses sont fixées entre les extrémités des longerons perpendiculairement à ceux-ci.The sleepers are fixed between the ends of the rails perpendicular to them.

De même, chaque longeron 3 et traverse 4 est réalisé en un matériau à base de carton comprenant une âme 7 en nid d'abeille en carton rigide en flexion prise en sandwich entre deux feuilles de carton 8, 9, dont l'une 8 constitue la face d'appui au sol du cadre de sommier comme cela ressort mieux de la figure 4.Similarly, each spar 3 and cross member 4 is made of a cardboard-based material comprising a honeycomb core 7 rigid cardboard bending sandwiched between two sheets of cardboard 8, 9, one of which 8 constitutes the support face on the floor of the bed frame as it is better figure 4 .

Ainsi, en position assemblée des longerons et traverses 3, 4 à la plaque de couchage 2, les alvéoles en nid d'abeille des longerons 3, des traverses 4 et de la plaque de couchage 2 sont orientées dans la même direction perpendiculaire au plan de la plaque 2 de manière à conférer à cet ensemble la rigidité nécessaire en flexion pour supporter un matelas et le poids de personnes.Thus, in the assembled position of the longitudinal members and sleepers 3, 4 to the sleeping plate 2, the honeycomb cells of the longitudinal members 3, crosspieces 4 and of the sleeping plate 2 are oriented in the same direction perpendicular to the plane of the plate 2 so as to give this set the necessary bending stiffness to support a mattress and the weight of people.

Les longerons 3 et les traverses 4 sont reliés respectivement aux quatre bords longitudinaux et transversaux situés dans un même plan correspondant à la face de couchage de la plaque 2 par des lignes d'articulation 10 permettant aux longerons 3 et traverses 4 d'occuper une position avant confection de la structure de sommier à laquelle ils se trouvent écartés de chaque côté de la plaque de couchage 2 sensiblement dans le même plan que celle-ci de manière que cet ensemble soit préfabriqué en usine pour présenter la forme générale d'un planche et livré à une usine de confection de sommiers où les longerons 3 et traverses 4 peuvent alors être assemblés en cadre de sommier en rabattant ou relevant autour de leurs lignes d'articulation 10 les longerons 3 et traverses 4 respectivement sur les quatre côtés 11 en feuilles de carton de la plaque de couchage 2 en faisant saillie de la face 6 de la plaque 2 opposée à sa face de couchage.The beams 3 and the crosspieces 4 are respectively connected to the four longitudinal and transverse edges situated in the same plane corresponding to the coating face of the plate 2 by hinge lines 10 allowing the longitudinal members 3 and cross members 4 to occupy a position before making the bed frame structure to which they are spaced apart on each side of the sleeping plate 2 substantially in the same plane as the latter so that this assembly is prefabricated at the factory to have the general shape of a board and delivered to a box spring manufacturing plant where the longitudinal members 3 and cross members 4 can then be assembled in a box spring frame by folding or raising around their hinge lines 10 the longitudinal members 3 and cross members 4 respectively on the four sides 11 in sheets of cardboard sleeping plate 2 protruding from the face 6 of the plate 2 opposite to its coating face.

De préférence, chaque longeron 3 et traverse 4 présente en section transversale une forme en trapèze rectangle dont le côté incliné de la feuille 9 vient en appui, en position relevée du longeron 3 ou de la traverse 4, contre le côté incliné conjugué correspondant 11 de la plaque de couchage 2, le côté ou face en feuille de carton 12 de chaque longeron 3 et traverse 4 constituant la petite base du trapèze rectangle étant perpendiculaire à la plaque de couchage 2 à sa position relevée en faisant saillie au-dessus de la face 6 de la plaque opposée à sa face de couchage. Les côtés 9 des longerons 3 et des traverses 4 et les côtés de la plaque de couchage 2 sont inclinés de 45° par rapport à l'horizontale.Preferably, each spar 3 and crosspiece 4 has in cross section a rectangular trapezoidal shape whose inclined side of the sheet 9 bears, in the raised position of the spar 3 or the crossbar 4, against the corresponding conjugate inclined side 11 of the sleeping plate 2, the side or face of cardboard sheet 12 of each spar 3 and 4 crosses constituting the small base of the rectangle trapezium being perpendicular to the sleeping plate 2 in its raised position protruding above the face 6 of the plate opposite its sleeping surface. The sides 9 of the longitudinal members 3 and cross members 4 and the sides of the coating plate 2 are inclined at 45 ° relative to the horizontal.

Chaque longeron 3 et chaque traverse 4 a ses faces d'extrémités opposées en feuilles de carton 13 inclinées en sens inverse l'une de l'autre d'environ 45° par rapport à l'horizontale de manière qu'en position relevée des longerons 3 et traverses 4 à leur position représentée en figure 4, les faces d'extrémités adjacentes 13 d'un longeron 3 et d'une traverse 4 soient en appui l'une contre l'autre pour constituer le coin correspondant du cadre du support de la plaque de couchage 2.Each spar 3 and each cross member 4 has its opposite end faces of cardboard sheets 13 inclined in opposite directions to each other by approximately 45 ° relative to the horizontal so that in the raised position of the spars 3 and sleepers 4 at their position represented in figure 4 , the adjacent end faces 13 of a spar 3 and a cross member 4 bear against each other to form the corresponding corner of the support frame of the sleeping plate 2.

Chaque ligne d'articulation 10 relie l'arête de base du côté incliné 9 de la forme en trapèze du longeron 3 ou de la traverse 4 correspondant à l'arête de base du côté incliné associé 11 de la plaque de couchage 2, cette dernière arête correspondant au bord de la plaque 2 côté face de couchage de cette plaque.Each hinge line 10 connects the base edge of the inclined side 9 of the trapezoidal shape of the spar 3 or of the cross member 4 corresponding to the base edge of the associated inclined side 11 of the sleeping plate 2, the latter edge corresponding to the edge of the plate 2 facing side of this plate.

La ligne d'articulation 10 reliant chaque longeron 3 et traverse 4 à la plaque de couchage 2 peut être assurée par la feuille de carton souple constituant la face supérieure de couchage de la plaque de couchage 2 se prolongeant de chaque côté de cette plaque pour constituer également la face d'un longeron 3 et d'une traverse 4 constituant la grande base de ce longeron et de cette traverse, opposée à la feuille constituant le côté 12 de la petite base de ce trapèze.The hinge line 10 connecting each spar 3 and 4 crosses to the coating plate 2 can be provided by the flexible cardboard sheet constituting the upper coating face of the sleeping plate 2 extending on each side of this plate to form also the face of a spar 3 and a cross member 4 constituting the large base of the spar and this cross, opposite the sheet constituting the side 12 of the small base of this trapezium.

Les longerons 3 et les traverses 4 peuvent être fixés les uns aux autres à leur position relevée de cadre de support de la plaque de couchage 2 par agrafage et/ou collage de leurs faces d'extrémités inclinées adjacentes 13. En outre, les longerons 3 et les traverses 4 peuvent être fixés par collage de leurs faces inclinées 9 respectivement aux quatre faces inclinées conjuguées 11 de la plaque de couchage 2.The beams 3 and the cross members 4 can be fixed to each other in their raised position of the support frame of the sleeping plate 2 by stapling and / or gluing their adjacent inclined end faces 13. In addition, the longitudinal members 3 and the crosspieces 4 can be fixed by bonding their inclined faces 9 respectively to the four conjugate inclined faces 11 of the coating plate 2.

L'invention peut également s'appliquer à des dosserets de literie généralement associés à la structure de sommier, ce dosseret étant ainsi réalisé en un matériau à base de carton comprenant une âme en nid d'abeille en carton rigide en flexion et prise en sandwich entre deux feuilles de carton collées à l'âme et constituant les faces avant et arrière du dosseret.The invention can also be applied to bedding backrests generally associated with the bed base structure, this backsplash thus being made of a cardboard-based material comprising a honeycomb core made of rigid cardboard in flexion and sandwiched between two sheets of cardboard glued to the soul and constituting the front and rear faces of the backsplash.

Selon un autre mode de réalisation, le sommier de literie pourrait être constitué tout simplement par la plaque de couchage 2 ayant les mêmes caractéristiques que celles du mode de réalisation décrit précédemment, cette plaque de couchage étant supportée uniquement par quatre pieds solidaires respectivement des quatre coins de la plaque 2. Cette dernière peut également comporter deux ou plusieurs autres plaques de couchage superposées les unes sur les autres ayant chacune la même structure alvéolaire en nid d'abeille rigide en flexion et prise en sandwich entre deux feuilles de carton collées à l'âme 5 de la plaque 2. Un tel agencement permet de rigidifier davantage en flexion la structure de couchage.According to another embodiment, the bed base could be constituted simply by the sleeping plate 2 having the same characteristics as those of the embodiment described above, this sleeping plate being supported only by four integral feet respectively of the four corners. of the plate 2. The latter may also comprise two or more other sleeping plates superimposed on each other each having the same rigid honeycomb honeycomb structure bent and sandwiched between two sheets of cardboard glued to the 5 of the plate 2. Such an arrangement makes it possible to further stiffen the bending structure flexibly.

Les figures 6 à 10 représentent un second mode de réalisation préféré d'un sommier de l'invention.The Figures 6 to 10 represent a second preferred embodiment of a bed base of the invention.

Selon ce second mode de réalisation, le sommier est préfabriqué à partir d'une plaque de base rectangulaire 14 en un matériau à base de carton comprenant une âme 5 en nid d'abeille en carton à alvéoles orientés verticalement en position d'utilisation du sommier pour procurer à l'âme 5 sa rigidité en flexion comme dans le premier mode de réalisation, l'âme étant prise en sandwich entre deux feuilles de carton 6.According to this second embodiment, the bed base is prefabricated from a rectangular base plate 14 of a cardboard-based material comprising a core 5 cardboard honeycomb with vertically oriented cells in the use position of the bed base to provide the core 5 with its bending stiffness as in the first embodiment, the core being sandwiched between two sheets of cardboard 6 .

La plaque de base 14 est ensuite découpée pour réaliser dans celle-ci quatre rainures 15, 16 encadrant une plaque interne rectangulaire constituant la plaque de couchage 2 et définir deux longerons 3 et deux traverses 4 externes et parallèles respectivement aux côtés longitudinaux et transversaux de la plaque de couchage 2. Ainsi, en retirant par découpage les quatre parties rectangulaires aux quatre coins de la plaque de base 14 et symbolisées par les diagonales se croisant en traits mixtes, on réalise un genre de "patron" du sommier dont les deux longerons 3 ont une longueur égale à la longueur de la plaque de couchage 2 et les deux traverses 4 ont une longueur inférieure à la largeur de la plaque de couchage 2 de telle manière qu'en fixant les longerons 3 et les traverses 4 sous la plaque de couchage comme représenté aux figures 9 et 10, les traverses 4 soient disposées entre les longerons 3 au voisinage de leurs extrémités pour constituer le cadre rectangulaire de support de la plaque de couchage 2. En outre, comme représenté en figure 1 et donc avant de réaliser le sommier, les longerons 3 et les traverses 4 sont reliés à la plaque de couchage 2 uniquement par des parties de liaison souples 6a constituant le fond des rainures longitudinales 15 et transversales 16 et appartenant, après réalisation de ces rainures, à la feuille de carton 6 recouvrant dans un même plan la plaque de couchage 2, les longerons 3 et les traverses 4. Les parties souples 6a de liaison des longerons 3 et des traverses 4 à la plaque 2 permettent aux longerons 3 et traverses 4 d'être rabattus, lors de la confection du sommier, sous la plaque de couchage 2 de manière que les côtés externes des longerons 3 et traverses 4 soient situés dans le même plan que les côtés longitudinaux et transversaux correspondants de la plaque de couchage 2 comme cela ressort des figures 9 et 10. Pour cela, la largeur 1 des parties souples 6a reliant les longerons 3 et traverses 4 aux côtés longitudinaux et transversaux de la plaque de couchage 2 est égale au double de l'épaisseur e de la plaque 2, des longerons 3 et des traverses 4.The base plate 14 is then cut to produce therein four grooves 15, 16 framing a rectangular inner plate constituting the sleeping plate 2 and defining two longitudinal members 3 and two cross members 4 external and parallel respectively to the longitudinal and transverse sides of the 2. Thus, by cutting out the four rectangular portions at the four corners of the base plate 14 and symbolized by the diagonals crossing in phantom, we realize a kind of "boss" of the bed whose two spars 3 have a length equal to the length of the sleeping plate 2 and the two sleepers 4 have a length less than the width of the sleeping plate 2 so that by fixing the longitudinal members 3 and the cross members 4 under the sleeping plate as represented at Figures 9 and 10 , the crosspieces 4 are arranged between the longitudinal members 3 near their ends to form the rectangular support frame of the sleeping plate 2. In addition, as shown in FIG. figure 1 and therefore before making the bed base, the longitudinal members 3 and crosspieces 4 are connected to the coating plate 2 only by flexible connecting portions 6a constituting the bottom of the longitudinal grooves 15 and transverse 16 and belonging, after completion of these grooves, to the sheet of cardboard 6 covering in the same plane the sleeping plate 2, the longitudinal members 3 and the cross members 4. The flexible portions 6a connecting the longitudinal members 3 and cross members 4 to the plate 2 allow the longitudinal members 3 and cross members 4 folded, when making the bed base, under the sleeping plate 2 so that the outer sides of the longitudinal members 3 and 4 sleepers are located in the same plane that the corresponding longitudinal and transverse sides of the sleeping plate 2 as Figures 9 and 10 . For this, the width 1 of the flexible parts 6a connecting the longitudinal members 3 and cross members 4 to the longitudinal and transverse sides of the coating plate 2 is equal to twice the thickness e of the plate 2, the longitudinal members 3 and the cross members 4.

Pour permettre aux deux traverses 4 d'être disposées entre les extrémités correspondantes des deux longerons 6 lorsque rabattus sous la plaque de couchage 2, les traverses 4 sont bien entendu au préalable disposées symétriquement au plan médian longitudinal de la plaque de couchage 2 et les extrémités de chaque traverse 4 sont chacune situées à une distance du côté longitudinal correspondant de la plaque de couchage 2 égale à la largeur d'un longeron 3, cette largeur étant égale à l'épaisseur de ce longeron lorsque les longerons 3, tout comme les traverses 4, sont constitués chacun par un parallélépipède à section transversale carrée.To allow the two crosspieces 4 to be disposed between the corresponding ends of the two longitudinal members 6 when folded under the coating plate 2, the crosspieces 4 are of course arranged beforehand symmetrically to the longitudinal median plane of the coating plate 2 and the ends of each crossmember 4 are each located at a distance from the corresponding longitudinal side of the coating plate 2 equal to the width of a spar 3, this width being equal to the thickness of this spar when the side members 3, as the cross members 4 are each constituted by a parallelepiped with a square cross section.

Comme pour le premier mode de réalisation, les longerons 3 et les traverses 4 sont reliés les uns aux autres, en position rabattue sous la plaque 2, par agrafage et/ou collage et les longerons et traverses sont fixés à la face correspondante de la plaque 2 par collage.As for the first embodiment, the longitudinal members 3 and the cross members 4 are connected to each other, in the folded position under the plate 2, by stapling and / or gluing and the longitudinal members and crosspieces are fixed to the corresponding face of the plate 2 by gluing.

Selon ce second mode de réalisation, le sommier peut être facilement préfabriqué dans sa vue développée en figure 6 à partir d'une plaque de base en carton à âme en nid d'abeille dont les alvéoles de la plaque de couchage 2, des longerons 3 et des traverses 4 sont verticaux en vue de dessus de la figure 6. Les fabricants de sommiers peuvent ensuite très facilement et rapidement réaliser un sommier à partir de la structure développée de la figure 6 en rabattant les longerons 3 et les traverses 4 sur la face correspondante de la plaque de base 2 de manière que ces longerons et traverses aient leurs alvéoles orientées verticalement comme représenté aux figures 9 et 10.According to this second embodiment, the bed base can be easily prefabricated in its developed view. figure 6 from a honeycomb core cardboard base plate, the cells of the sleeping plate 2, longitudinal members 3 and cross members 4 are vertical in plan view from above. figure 6 . Springboard manufacturers can then very easily and quickly build a box spring from the developed structure of the figure 6 by folding the longitudinal members 3 and the cross members 4 on the corresponding face of the base plate 2 so that these longitudinal members and sleepers have their vertically oriented cells as shown in Figures 9 and 10 .

Les essais ont montré qu'un sommier fabriqué à partir de carton à structure en nid d'abeille offre une excellente résistance compatible avec les contraintes liées à l'utilisation et, le cas échéant, des renforts structurels peuvent être prévus pour améliorer la résistance des longerons et traverses solidaires de la plaque de couchage 2.The tests have shown that a bed base made from honeycomb structural board offers excellent resistance compatible with the constraints of use and, where appropriate, structural reinforcements may be provided to improve the strength of the structures. rails and sleepers integral with the sleeping plate 2.
