Each body has two opposite fixing feet (18a) that are staggered laterally and are parallel. Each foot has a transversal hole that engages on a transversal axle (25). The two feet of successive bodies engage on the same axle to form a continuous chain of caps.

Description

La présente invention concerne un dispositif destiné à la fixation de lattes transversales d'un sommier de literie.The present invention relates to a device for fixing transverse slats of a bed base.

L'invention s'applique en particulier à des sommiers à dossier et support de jambes d'un utilisateur relevables manuellement ou par un mécanisme motorisé commandé à distance à l'aide d'un boítier de commande approprié.The invention applies in particular to backrest and leg support of a lift-up user manually or by a motorized mechanism controlled by distance using a suitable control box.

De tels sommiers comprennent d'une manière générale un châssis sur lequel sont articulées au moins deux parties relevables respectivement de dossier et de support des jambes d'un utilisateur, chacune en forme de cadre comportant des lattes. Le dispositif de fixation des lattes à chacun de ces cadres comprend des embouts fixés aux deux longerons de chaque cadre et destinés à recevoir et supporter les extrémités correspondantes des lattes. Chaque embout comprend un corps de fixation de celui-ci au longeron correspondant et au moins une partie en capuchon présentant la forme d'un capuchon de réception d'une extrémité d'une latte. Chaque partie supérieure est fixée sur le corps de l'embout par une partie de liaison relativement souple et d'une hauteur telle que la partie en capuchon est surélevée relativement au bord supérieur du longeron correspondant.Such bedsteads generally comprise a chassis on which at least two parts are articulated respectively of the file and the support of the user's legs, each shaped like a frame with slats. The device for fixing slats to each of these frames includes fixed end caps to the two longitudinal members of each frame and intended to receive and support the corresponding ends of the slats. Each endpiece comprises a fastening body thereof to the corresponding spar and at least a part thereof cap in the shape of a receiving cap from one end of a slat. Each upper part is fixed on the body of the mouthpiece by a connecting part relatively flexible and of a height such that the part cap is raised relative to the upper edge the corresponding spar.

Une telle conception d'embouts de support de lattes a pour inconvénient d'aboutir à un montage flottant des lattes de sorte que celles-ci peuvent se déplacer le long de leurs axes longitudinaux avec les embouts, aboutissant ainsi à une fixation instable de ces lattes. En outre, les embouts de support des lattes sont fixés à leur longeron correspondant indépendamment les uns des autres de sorte qu'il est difficile de respecter des distances entre embouts rigoureusement égales. De plus, la fixation des embouts au longeron correspondant s'effectue généralement par des vis de fixation, occasionnant ainsi une perte de temps lors de leur assemblage en usine aux longerons. Enfin, ce dispositif connu de fixation de lattes transversales se caractérise par l'absence systématique d'au moins une latte transversale entre deux cadres consécutifs articulés l'un par rapport à l'autre du sommier.Such a design of slatted support tips has for the inconvenience of resulting in a floating assembly of slats so that these can move along their longitudinal axes with the end pieces, culminating thus to an unstable fixation of these slats. In addition, the support ends of the slats are fixed to their spar corresponding independently of each other so that it is difficult to respect distances between bits rigorously equal. In addition, fixation bits to the corresponding spar is made generally by fixing screws, thereby causing a waste of time when assembled in the factory at beams. Finally, this known device for fixing transverse slats is characterized by the absence systematically at least one latte transverse between two consecutive frames articulated relative to each other bedspring.

DE-A-44 41 476 décrit un dispositif de fixation de lattes transversales d'un sommier de literie conforme au préambule de la revendication 1. Plus précisément, ce document décrit plusieurs modes de réalisation d'un embout de suspension en pont à trois points pour des traverses de cadre inférieur de lit. Cependant, chaque embout de ces modes de réalisation ne peut assurer sa fonction de suspension qu'en étant déformé verticalement sous une charge résultant du poids de l'utilisateur allongé sur le sommier, c'est-à-dire que chaque embout ne peut être utilisé qu'horizontalement. Ainsi, ces embouts ne sont pas adaptables à une utilisation à deux longerons articulés de deux cadres articulés d'une partie relevable d'un sommier où se pose le problème de déformation de l'embout dans une direction autre que verticale.DE-A-44 41 476 discloses a lath fixing device cross section of a bedstead conforming to preamble of claim 1. More specifically, this document describes several embodiments of a mouthpiece three-point suspension suspension for sleepers lower bed frame. However, each tip of these embodiments can not fulfill its function of suspension while being deformed vertically under a load resulting from the weight of the user lying on the sommier, that is to say that each end can not be used only horizontally. So, these tips are not adaptable to use with two articulated spars of two articulated frames of a lifting part of a bed base where there is the problem of deformation of the tip in a direction other than vertical.

La présente invention a pour but d'éliminer les inconvénients ci-dessus des dispositifs connus.The present invention aims to eliminate the disadvantages above known devices.

A cet effet, l'invention propose un dispositif destiné à la fixation de lattes transversales d'un sommier de literie comprenant les caractéristiques énoncées dans la partie caractérisante de la revendication 1 ou 17. For this purpose, the invention proposes a device intended to the fixing of transverse slats of a bed base of bedding including the features set out in the characterizing part of claim 1 or 17.

Les chaínes continues d'embouts de longerons de cadres d'un même côté sont situées dans un même plan vertical longitudinal.Continuous chains of frame side members on the same side are located in the same vertical plane longitudinal.

Chaque corps d'embout comprend deux pattes de fixation extrêmes opposées parallèles percées transversalement de façon à permettre leur engagement respectivement sur deux axes de support transversaux solidaires du longeron correspondant, les deux pattes de fixation respectivement de deux corps d'embouts successifs s'engageant sur un axe de support transversal commun pour former la chaíne continue d'embout.Each end body has two fixing lugs opposite extreme parallels pierced transversely of way to enable their commitment respectively on two transverse support pins secured to the spar corresponding, the two brackets respectively of two bodies of successive tips engaging on one axis common transverse support to form the chain continues tip.

Les pattes de fixation de chaque corps d'embout sont décalées latéralement l'une par rapport à l'autre de façon qu'en engageant les pattes de fixation des corps d'embouts successifs d'une chaíne continue sur leurs axes de support communs respectifs, les corps d'embout et leurs parties de réception d'extrémités de lattes s'étendent d'une même distance de la face interne du longeron correspondant.The fastening lugs of each end body are shifted laterally relative to each other way that by engaging the fasteners of the body successive bits of a continuous chain on their axes respective support brackets, the tip bodies and their slat end receiving parts extend from the same distance from the inner face of the corresponding spar.

De préférence, les distances entre perçages de pattes d'embouts sont égales.Preferably, the distances between piercing of legs bits are equal.

Les parties de réception des extrémités des lattes sont fixées sur leurs corps respectifs par des pieds relativement rigides transversalement assurant une stabilité des lattes dans leurs directions longitudinales. The receiving parts of the ends of the slats are fixed on their respective bodies by feet relatively rigid transversely ensuring a slat stability in their directions longitudinal.

Les corps d'embouts sont fixés au longeron correspondant de façon que leurs parties de réception des extrémités des lattes soient approximativement au même niveau que le bord supérieur de ce longeron.The end bodies are attached to the corresponding spar so that their ends receiving parts slats are approximately the same level as the upper edge of this spar.

Avantageusement, les parties de réception des extrémités des lattes ont leurs fonds situés au voisinage de la face interne du longeron ou en contact avec celle-ci.Advantageously, the receiving parts of the ends slats have their funds located near the face inside the spar or in contact with it.

De préférence, les parties de réception des extrémités des lattes sont chacune en forme de capuchon à section transversale rectangulaire et transversal au longeron correspondant.Preferably, the receiving portions of the ends slats are each in the form of a section cap rectangular and transverse transverse to the spar corresponding.

Les deux cadres de la partie relevable de support des jambes sont reliés entre eux par deux articulations latérales en compas dont l'axe d'articulation de chacune comprend l'axe transversal de support commun à deux pattes de fixation respectivement des deux corps d'embouts consécutifs.The two frames of the lift support part of the legs are interconnected by two joints sides in compass whose axis of articulation of each includes the transverse axis of support common to both fastening lugs respectively of the two bodies consecutive tips.

Le cadre de la partie relevable du dossier est articulé de façon pivotante aux pans du châssis du sommier par deux axes transversaux et deux, consécutifs, des corps d'embouts de chaque chaíne continue du longeron du cadre du dossier et d'un longeron adjacent du cadre fixe définissant avec le cadre du dossier la zone fessière sont reliés en commun à l'axe d'articulation correspondant du cadre du dossier de façon que le corps d'embout associé au cadre du dossier puisse pivoter autour de cet axe lors du déplacement du cadre du dossier.The frame of the lifting part of the backrest is articulated pivotally to the sides of the bed frame by two transverse axes and two, consecutive, bodies ends of each continuous chain of the frame spar backrest and an adjacent spar of the fixed frame defining with the frame of the file the gluteal area are connected in common to the axis of articulation matching the frame of the folder so that the body end piece associated with the backrest frame can rotate around this axis when moving the frame of the folder.

Chaque axe d'articulation du cadre du dossier est prolongé par un axe transversal de support de deux pattes de fixation respectivement des deux corps d'embouts consécutifs associés respectivement au cadre du dossier et au cadre fixe adjacent.Each axis of articulation of the frame of the file is extended by a transverse axis of support of two legs respectively fixing the two bodies of tips consecutive records associated respectively with the file and the adjacent fixed frame.

La partie de dossier relevable est réalisée sous forme d'une double têtière pouvant être télescopiquement allongée dans sa direction longitudinale lors du relevage de la partie du dossier et comprenant un premier cadre de support de lattes pourvu de longerons articulés de façon pivotante à une extrémité aux pans du châssis du sommier, une chaíne continue d'embouts de support des lattes étant fixée à chaque longeron du premier cadre et un second cadre de support à lattes à longerons monté sur le premier cadre de façon pivotante et télescopiquement mobile par rapport à celui-ci lors du relevage de la partie de dossier, une chaíne continue d'embouts étant fixée à chaque longeron du second cadre, et une partie de dossier escamotable à au moins une latte est prévue pour occuper automatiquement l'espace existant entre les premier et second cadres lorsque la partie de dossier est relevée, la latte de la partie escamotable étant supportée à chacune de ses extrémités par une plaque latérale par l'intermédiaire d'un embout à pattes de fixation monté sur deux axes de support transversaux de la plaque latérale disposée relativement au châssis du sommier de façon que l'embout qu'elle supporte et les embouts des chaínes latérales continues respectivement des premier et second cadres soient dans le même plan vertical longitudinal.The liftable backrest portion is formed in form a double headrest that can be telescopically lengthened in its longitudinal direction when lifting part of the file and including a first slat support provided with articulated spars pivoting at one end to the sides of the bed frame, a continuous chain of support ends of the slats being attached to each spar of the first frame and a second support frame with stringer slats mounted on the first frame pivotally and telescopically moving relative to it when lifting the part of file, a continuous chain of bits being attached to each spar of the second frame, and a portion of retractable backrest with at least one lath is provided for automatically occupy the existing space between first and second frames when the file part is raised, the lath of the retractable part being supported at each end by a plate side by means of a toe cap mounted on two transverse support axes of the side plate disposed relative to the frame of the bed base so that the endpiece that it supports and the ends of continuous side chains respectively first and second frames are in the same plane longitudinal vertical.

Avantageusement, chacune des paires adjacentes de longerons respectivement des deux cadres articulés de la partie relevable de support des jambes est pourvue d'un cache recouvrant l'espace libre entre les deux extrémités en vis-à-vis respectivement de deux longerons adjacents.Advantageously, each of the adjacent pairs of longitudinal members respectively of the two articulated frames of the lifting part of leg support is provided with a cache covering the free space between the two ends vis-à-vis respectively two adjacent spars.

De préférence, le cache comprend deux coquilles articulées l'une par rapport à l'autre et fixées par emboítement respectivement sur les deux extrémités des longerons, l'une des coquilles comprenant une partie d'extrémité mâle s'engageant dans une partie d'extrémité femelle de l'autre coquille de façon à constamment occulter l'espace entre les longerons adjacents lors du relevage ou de l'abaissement des deux cadres articulés de la partie relevable de support des jambes.Preferably, the cache comprises two shells articulated relative to one another and fixed by nesting respectively on both ends of spars, one of the shells comprising a part male end engaging in an end portion female of the other shell so as to constantly obscure the space between the adjacent spars when raising or lowering of the two articulated frames of the lift leg support.

Les embouts sont réalisés en une matière à base de caoutchouc ou de matière plastique souple et sont montés chacun amoviblement sur leurs axes de support respectifs par leurs pattes de fixation engagées élastiquement sur ces axes de support.

En se reportant aux figures 1 et 2, le sommier de literie représenté est du type comprenant un châssis 1 en forme de cadre à longerons 2 et traverses 3, sur lequel sont articulées plusieurs parties relevables situées de part et d'autre d'une partie fixe 4 correspondant à la zone fessière de l'utilisateur et comprenant une partie relevable de dossier 5 sur laquelle peut s'appuyer le dos et la tête de l'utilisateur et deux parties relevables articulées entre elles 6, 7 correspondant aux jambes de l'utilisation. La partie relevable de dossier 5 est constituée par un cadre à longerons 8 et traverses 9, chaque longeron 8 ayant son extrémité située vers la zone fessière fixée de façon pivotante aux longerons ou pans 2 du sommier sur un axe d'articulation 10 solidaire du longeron 2. Comme cela ressort mieux de la figure 7, la partie de dossier relevable 5 est en fait réalisée sous forme d'une double têtière pouvant être télescopiquement allongée dans sa direction longitudinale lors du relevage de la partie 5 et qui comporte un premier cadre 11 de support de lattes 12, dont deux sont seulement représentés partiellement, pourvu des longerons 8 articulés de façon pivotante aux longerons 2 du sommier, un second cadre 13 de support de lattes 12 à longerons 8, monté sur le premier cadre 11 de façon pivotante et télescopiquement mobile par rapport à ce dernier lors du relevage de la partie de dossier 5. Un mécanisme à bras pivotants et biellettes, généralement référencé en 14 en figure 7, permet le relevage des deux cadres 11, 13 à des positions souhaitées d'appui du dos et de la tête de l'utilisateur et d'une partie de dossier 15 de support d'au moins une latte, automatiquement escamotable et déplaçable entre une position escamotée sous la zone fessière lorsque la partie de dossier 5 n'est pas relevée et une position à laquelle la latte occupe l'espace entre les deux cadres 11 et 13 lorsque la partie de dossier 5 est relevée. La partie de dossier 5 à double têtière et son mécanisme de relevage associé sont décrits de façon détaillée dans la demande de brevet français N° 9510108 déposée le 25 Août 1995 au nom de la demanderesse. Il suffit donc de se reporter à la description de cette demande de brevet français qui est ici incorporée à titre de référence. Les lattes transversales 12 sont supportées entre les longerons 8 des cadres 11 et 13 de la partie de dossier 5 par des embouts 16 fixés à la paroi interne de chaque longeron 8 et comportant chacun au moins une partie en forme de capuchon 17, dans laquelle pénètre une extrémité correspondante d'une latte, solidaire d'un corps 18 de l'embout 16 fixé au longeron 8. Les embouts 16 sont réalisés à partir d'une matière à base de caoutchouc ou de matière plastique souple et sont intégralement moulés.Referring to Figures 1 and 2, the bed frame shown is of the type comprising a chassis 1 in form frame members 2 and cross members 3, on which are articulated several liftable parts located from and other of a fixed part 4 corresponding to the zone buttocks of the user and including a part lift of file 5 on which can lean back and the user's head and two liftable parts articulated together 6, 7 corresponding to the legs of use. The lifting part of file 5 is constituted by a frame with longitudinal members 8 and cross members 9, each spar 8 having its end located towards the zone buttocks pivotally attached to spars or shanks 2 of the bed base on an axis of articulation 10 integral with the 2. As can be seen from Figure 7, the part of liftable backrest 5 is actually carried out under a double headrest that can be telescopically lengthened in its longitudinal direction when lifting of Part 5 and which includes a first box 11 of support slats 12, two of which are only partially shown, provided with longitudinal members 8 articulated pivotally to the longitudinal members 2 of the bed base, a second support frame 13 for slats 12 with longitudinal members 8, mounted on the first frame 11 pivotally and telescopically mobile with respect to the latter during the lifting of the back portion 5. An arm mechanism swivels and links, generally referenced in 14 in FIG. 7 allows the two frames 11, 13 to be lifted to desired positions of support of the back and the head of the user and a support folder part 15 at least one lath, automatically retractable and movable between a retracted position under the zone buttocks when the backrest portion 5 is not raised and a position at which the latte occupies the space between the two frames 11 and 13 when the file part 5 is raised. The backrest part 5 with double headrest and its associated lifting mechanism are described in such a way in French patent application No. 9510108 filed on August 25, 1995 in the name of the plaintiff. he so just have to refer to the description of this French patent application which is incorporated herein by reference reference. The transverse slats 12 are supported between the rails 8 of the frames 11 and 13 of the part of backrest 5 by end caps 16 attached to the inner wall of each spar 8 and each comprising at least one cap-shaped portion 17, into which a corresponding end of a slat, attached to a body 18 of the endpiece 16 attached to the spar 8. The end pieces 16 are made from a material based on rubber or soft plastic material and are integrally molded.

Les deux parties relevables 6, 7 de support des jambes sont chacune constituée par un cadre à longerons 19 entre lesquels sont supportées des lattes (non représentées), chaque longeron 19 du cadre 6 ayant son extrémité située à proximité du cadre fixe 4 articulée de façon pivotante autour d'un axe transversal 20 solidaire du longeron 2 du sommier, tandis que chaque longeron 19 de l'autre cadre 7 a son extrémité opposée au cadre 6 également articulée de façon pivotante autour d'un axe transversal 21 solidaire du longeron 2. Les lattes des cadres 6, 7 sont supportées à leurs extrémités par des embouts 16 identiques aux embouts 16 de la figure 7 et fixés à la face interne des longerons 19 de ces cadres.The two lifting parts 6, 7 of leg support each consist of a frame with longitudinal members 19 between which are supported slats (not shown), each spar 19 of the frame 6 having its end located near the fixed frame 4 hinged pivotally around a transverse axis 20 secured to the spar 2 of the sommier, while each spar 19 of the other frame 7 at its opposite end to the also articulated frame 6 of pivoting way around a transverse axis 21 secured of the spar 2. The slats of the frames 6, 7 are supported at their ends by end pieces 16 identical to end pieces 16 of FIG. 7 and fixed to the internal face of the longitudinal members 19 of these frames.

Les longerons 22 du cadre fixe 4 sont solidarisés aux longerons 2 du sommier par des vis de fixation 23 et les lattes (non représentées) de ce cadre sont également supportées à leurs extrémités par des embouts 16 fixés à la face interne de chaque longeron 22 et identiques aux embouts 16 de la figure 7.The rails 22 of the fixed frame 4 are secured to the longitudinal members 2 of the bed base by fixing screws 23 and the slats (not shown) of this frame are also supported at their ends by end caps 16 attached to the inner face of each spar 22 and identical to the end pieces 16 of FIG.

Les cadres 6, 7 peuvent être relevés ou abaissés par un mécanisme à bras pivotants et biellettes 24, connu en soi, et qui n'a pas à être davantage détaillé car ne faisant pas partie de l'invention.The frames 6, 7 can be raised or lowered by a mechanism with pivoting arms and links 24, known in self, and which does not have to be more detailed because not part of the invention.

Un ensemble motorisé (non représenté) permet de commander les mécanismes de relevage des parties 5, 6 et 7 du sommier à l'aide d'un boítier de commande.A motorized assembly (not shown) makes it possible to control the lifting mechanisms of Parts 5, 6 and 7 of sommier using a control box.

Selon l'invention, les embouts 16 sont fixés au longeron correspondant de chacun des cadres 4, 6, 7, 11 et 13 de manière à former une chaíne continue d'embouts espacés de façon équistante les uns des autres le long du longeron, avec les chaínes d'embouts de longerons d'un même côté des différents cadres fixe et relevables situées dans un même plan vertical longitudinal.According to the invention, the endpieces 16 are attached to the spar corresponding to each of the frames 4, 6, 7, 11 and 13 of way to form a continuous chain of bits spaced from equistently from each other along the spar, with chains of end pieces of spars on the same side different fixed and lifting frames located in a same longitudinal vertical plane.

A cet effet, comme représenté en particulier aux figures 3 à 6, le corps 18 de chaque embout 16 comprend deux pattes de fixation extrêmes opposées parallèles 18a ayant chacune un perçage transversal 18b de façon à permettre leur engagement respectivement sur deux axes de support transversaux 25 solidaires du longeron correspondant du cadre 4, 6, 7, 11 et 13 et sur lequel est montée la chaíne continue d'embouts 16. Comme cela ressort notamment des figures 7 et 11, les deux pattes de fixation 18a respectivement de deux embouts successifs 16 sont montées sur un axe de support transversal commun 25 pour former la chaíne continue d'embouts. La figure 4 montre que les deux pattes de fixation 18a de chaque embout 16 sont décalées latéralement l'une par rapport à l'autre de façon qu'une fois les embouts 16 emmanchés sur leurs axes de support respectifs 25 pour former la chaíne continue, leurs parties 17 de réception d'extrémités de lattes et leurs corps 18 s'étendent d'une même distance de la face interne du longeron correspondant du cadre 4, 6, 7, 11 ou 13. Puisque les embouts 16 sont réalisés en une matière à base de caoutchouc, chacun d'eux est tout simplement monté en emmanchant leurs pattes de fixation 18a sur les axes de support respectifs 25 et ces pattes sont maintenues élastiquement et amoviblement sur les axes 25 sans qu'il soit nécessaire de prévoir d'autres moyens pour empêcher les embouts 16 de s'échapper latéralement de leurs axes de support 25. Ces derniers sont bien entendu fixés aux longerons des cadres 4, 6, 7, 11 et 13 à des distances égales le long de ceux-ci.For this purpose, as shown in particular in the figures 3 to 6, the body 18 of each endpiece 16 comprises two parallel opposite extreme mounting lugs 18a having each a transverse bore 18b so as to allow their commitment respectively on two support axes transverse 25 integral with the corresponding spar of the frame 4, 6, 7, 11 and 13 and on which is mounted the continuous chain of bits 16. As is apparent in particular FIGS. 7 and 11, the two legs of fixing 18a respectively of two successive tips 16 are mounted on a common transverse support axis 25 to form the continuous chain of bits. Figure 4 shows that the two brackets 18a of each endpiece 16 are offset laterally with respect to the other so that once the tips 16 fitted on their respective support pins 25 to form the chain continuous, their end-receiving parts 17 slats and their bodies 18 extend the same distance of the inner face of the corresponding spar of the frame 4, 6, 7, 11 or 13. Since the tips 16 are made of a rubber-based material, all of them are all simply mounted by hooking up their brackets 18a on the respective support pins 25 and these legs are held elastically and removably on the axes 25 without the need to provide for other means for preventing the tips 16 from escaping laterally of their support axes 25. The latter are of course fixed to the longitudinal members of the frames 4, 6, 7, 11 and 13 at equal distances therealong.

Les parties 17 de réception des extrémités des lattes 12 sont fixées sur leurs corps respectifs 18 par des pieds 18c qui sont relativement rigides transversalement pour assurer une stabilité des lattes dans leurs directions longitudinales. Les corps 18 des embouts 16 sont fixés aux longerons correspondants de façon que leurs parties de réception 17 des extrémités de lattes 12 soient approximativement au même niveau que le bord supérieur de ce longeron et, de préférence, les parties de réception 17 ont leurs fonds situés au voisinage de la face interne du longeron ou en contact avec celle-ci.The parts 17 for receiving the ends of the slats 12 are attached to their respective bodies 18 by feet 18c which are relatively rigid transversely for ensure slat stability in their directions longitudinal. The bodies 18 of the end pieces 16 are fixed to the corresponding spars so that their parts 17 of the ends of slats 12 are approximately the same level as the top edge of this spar and, preferably, the receiving parts 17 have their funds in the vicinity of the inner face the spar or in contact with it.

Les figures 4 et 5 montrent la forme en capuchon de chacune des parties de réception 17 des extrémités des lattes et présentant une section transversale sensiblement rectangulaire de forme conjuguée à celle des extrémités des lattes. La figure 6 montre un embout 16 dont la partie de réception 17 est en appui par ses bords latéraux sur le corps 18 par déformation élastique en compression du pied 18c résultant d'une charge verticale appliquée par l'extrémité correspondante d'une latte lorsqu'un utilisateur est allongé sur les lattes du sommier.Figures 4 and 5 show the hooded shape of each of the receiving parts 17 of the ends of the slats and having a cross section substantially rectangular shape conjugate to that of ends of the slats. Figure 6 shows a tip 16 whose receiving part 17 is supported by its edges on the body 18 by elastic deformation in compression of the foot 18c resulting from a vertical load applied by the corresponding end of a slat when a user is lying on the slats of the bedspring.

Les perçages 18b des pattes 18a des embouts 16 situées du côté de la face intérieure du longeron correspondant débouchent de part et d'autre de ces pattes, mais les autres perçages des pattes 18a éloignées du longeron sont des trous borgnes comme représenté en figure 4 de façon à cacher les extrémités des axes de support correspondants 25 lorsque les chaínes d'embouts sont formées.The holes 18b of the tabs 18a of the end pieces 16 located in the side of the inner side of the corresponding spar open on either side of these legs, but the other holes 18a legs remote from the spar are blind holes as shown in Figure 4 so as to hide the ends of the corresponding support pins 25 when the end chains are formed.

La continuité de chaque chaíne latérale d'embouts 16 peut être assurée entre les deux longerons adjacents 19 respectivement des deux cadres articulés entre eux 6 et 7 au niveau du genou d'un utilisateur. Les figures 8 à 10 représentent une réalisation permettant d'assurer une telle continuité de chaíne d'embouts 16. Ainsi, les longerons 19 des deux cadres 6, 7 de la partie relevable du support des jambes sont reliés entre eux par deux articulations latérales en compas. Chaque articulation en compas comprend deux bras 26, sensiblement en forme de plaque rectangulaire, fixés respectivement aux deux faces verticales internes des deux longerons adjacents 19 des cadres 6, 7 par des vis de fixation 27 ou d'autres moyens de fixation équivalents. L'axe d'articulation des bras 26 du compas est prolongé par un axe transversal 25 sur lequel peuvent s'engager deux pattes de fixation 18a respectivement de deux embouts consécutifs 16. Lorsque ces deux embouts consécutifs 16 sont montés sur leurs axes de support respectifs 25 pour former la chaíne continue d'embouts, les deux embouts adjacents 16 montés sur l'axe d'articulation du compas peuvent suivre, à la manière d'une chenille, les déplacements de cette articulation lors des mouvements de relevage ou d'abaissement de chaque paire de longerons 19 des cadres articulés 6, 7.The continuity of each lateral chain of bits 16 can be assured between the two adjacent spars 19 respectively of the two frames articulated between them 6 and 7 at the knee level of a user. Figures 8 to 10 represent an achievement to ensure a such continuity of chain bits 16. Thus, the longitudinal members 19 of the two frames 6, 7 of the lifting part legs support are interconnected by two lateral joints in compass. Each articulation in compass comprises two arms 26, substantially shaped rectangular plate, respectively fixed to both sides internal verticals of the two adjacent spars 19 frames 6, 7 by fixing screws 27 or other means equivalent fasteners. The axis of articulation of the arms 26 of the compass is extended by a transverse axis 25 on which can engage two brackets 18a respectively of two consecutive ends 16. Where these two consecutive tips 16 are mounted on their respective support pins 25 to form the chain continuous end caps, two adjacent end caps 16 mounted on the axis of articulation of the compass can follow, at the way of a caterpillar, the displacements of this articulation during lifting movements or lowering each pair of longitudinal members 19 of the frames articulated 6, 7.

Les figures 8 et 9 montrent également que chaque paire de longerons adjacents 19 des cadres 6, 7 est pourvue d'un cache 28 destiné à recouvrir en l'occultant l'espace libre entre les deux extrémités en vis-à-vis respectivement des deux longerons adjacents 19. Ce cache comprend deux coquilles 29 montées par emboítement respectivement sur les deux extrémités des longerons adjacents 19, l'une 29 des coquilles comprenant une partie d'extrémité mâle 30 s'engageant dans une partie d'extrémité femelle 31 de l'autre coquille 29, les formes des parties d'extrémité mâle 30 et femelle 31 des coquilles 29 étant agencées de façon à permettre à la fois l'articulation entre les deux coquilles 29 et l'occultation constante de l'espace entre les longerons 19 lors du relevage ou l'abaissement de ces longerons.Figures 8 and 9 also show that each pair of adjacent spars 19 of the frames 6, 7 is provided with a cache 28 intended to cover the occulting space free between the two ends vis-à-vis respectively of the two adjacent spars 19. This cache comprises two shells 29 mounted by interlocking respectively on both ends of the side members adjacent 19, one 29 of the shells comprising a male end portion 30 engaging in a portion female end 31 of the other shell 29, the shapes male and female end portions 31 of the shells 29 being arranged to allow the time the articulation between the two shells 29 and the constant occultation of the space between the longitudinal members 19 when raising or lowering these side members.

Les figures 11 à 13 montrent la continuité d'une chaíne d'embouts 16 entre le longeron 8 du cadre de la partie relevable de dossier 5 et le longeron 22 du cadre fixe 4. Pour cela, chaque axe de pivotement 10 du cadre du dossier est prolongé par un axe transversal de support 25 sur lequel sont engagées les deux pattes de fixation 18a respectivement de deux embouts consécutifs 16 dont l'un a son autre patte de fixation 18a engagée sur l'axe transversal de support extrême 25 du longeron 22 du cadre 4 et dont l'autre a sa patte de fixation 18a opposée à l'axe de pivotement engagée sur un axe de support 25 du longeron 8 du cadre de la partie du dossier 5. Il est à noter que les deux axes extrêmes 25 de chaque longeron 22 du cadre 4 prolonge respectivement les deux axes de fixation 23 de ce longeron au longeron 2 du sommier. Ainsi, le dernier embout 16 de chaque longeron du cadre de la partie de dossier 5 situé dans la zone fessière peut pivoter autour de l'axe 10 lors du mouvement de relevage ou d'abaissement de ce cadre.Figures 11 to 13 show the continuity of a chain of bits 16 between the spar 8 of the part frame lift of back 5 and the spar 22 of the fixed frame 4. For this, each pivot axis 10 of the frame of the backrest is extended by a transverse support shaft 25 on which are engaged the two fixing lugs 18a respectively of two consecutive tips 16, one of which has its other fixing lug 18a engaged on the axis transverse end support 25 of the frame spar 22 4 and the other has its bracket 18a opposite to the pivot axis engaged on a support axis 25 of the spar 8 of the frame of the part of the backrest 5. It is note that the two extreme axes 25 of each spar 22 frame 4 extends respectively the two axes of fixing 23 of this spar to the spar 2 of the bed. Thus, the last tip 16 of each frame spar of the file part 5 located in the gluteal area can rotate around the axis 10 during the movement of raising or lowering of this frame.

En se référant à nouveau à la figure 7, la partie de dossier automatiquement escamotable 15 comprend de chaque côté du sommier une plaque 32 reliée au mécanisme de pivotement 14 et comportant deux axes transversaux 25 solidaires de sa partie supérieure sur lesquels sont montées les deux pattes de fixation 18a d'un embout 16. Chaque plaque 32 de support d'un embout 16 est située à proximité du longeron 2 du sommier de façon que l'embout 16 qu'elle supporte soit situé dans le même plan vertical longitudinal des embouts 16 solidaires des longerons 8 des premier et second cadres 11, 13 de la partie formant dossier 5. De la sorte, lorsque la partie de dossier 5 est relevée, la partie de dossier 15 occupe sa position dans l'espace entre les premier et second cadres 11, 13 de façon que chaque embout 16 supporté par la plaque 32 soit situé entre les deux embouts extrêmes respectivement des deux longerons 8 de ces cadres pour assurer visuellement la continuité de chaque chaíne latérale continue d'embouts sur ces longerons.Referring again to Figure 7, the game of automatically retractable folder 15 includes each side of the bed frame a plate 32 connected to the mechanism of pivoting 14 and having two transverse axes 25 solidary of its upper part on which are mounted the two fastening lugs 18a of a tip 16. Each support plate 32 of a tip 16 is located at near the spar 2 of the bed base so that the endpiece 16 that it supports is located in the same vertical plane longitudinal ends 16 secured to the longitudinal members 8 first and second frames 11, 13 of the forming part 5. In this way, when the file part 5 is raised, the file part 15 occupies its position in the space between the first and second frames 11, 13 so that each tip 16 supported by the plate 32 is located between the two end caps respectively of the two longitudinal members 8 of these frames to ensure visually the continuity of each side chain continuous bits on these spars.

L'invention permet ainsi de réaliser une chaíne continue d'embouts sur pratiquement toute la longueur de chaque longeron du sommier de sorte que les lattes transversales sont pratiquement toutes situées à égale distance les unes des autres. De plus, la conception des embouts ainsi que, le cas échéant, leur fixation à proximité de la face interne du longeron correspondant de chaque cadre, évite le phénomène de flottement des lattes dans leurs directions longitudinales. Enfin, le montage des embouts sur leurs axes de support respectifs est extrêmement facile et ne nécessite pas d'outils particuliers et le remplacement d'un embout défectueux peut être aisément effectué même par l'utilisateur du sommier.The invention thus makes it possible to produce a continuous chain of tips over practically the entire length of each springboard spar so that the transverse slats are almost all located at equal distances each other. In addition, the design of the tips as well that, where appropriate, their fastening close to the face inside the corresponding spar of each frame, avoids the phenomenon of floating laths in their longitudinal directions. Finally, the assembly of the tips on their respective support axes is extremely easy and does not require any special tools and the replacing a defective tip can be easily performed even by the user of the bed base.
