Abstract

The stiffener is a rod (4) which has an asymmetrical cross section in the shape of a double T. The rod extends under a slat (1) and pivots in a heel (2) under the center of the slat and in guides (6) fixed to the end of the slat. The rod is mounted in a disc (5) that turns in a bearing (3) in the heel and it is mounted in pivoting discs (5) in the guides.

Description

L'invention se rapporte aux sommiers à lattes et concerne plus précisément un système raidisseur constitué d'un jonc tournant associé à une latte ou à un groupe de lattes du sommier.The invention relates to slatted bed bases and relates more precisely to a stiffening system consisting of a rotating rod associated with a slat or a group of bed slats.

Les lattes sont comme on le sait maintenues sur le cadre d'un sommier par des embouts de profil particulier, qui sont dans certains cas réalisés en matière élastomère, et dans lesquels alternent des supports élastiques et des espaces creux intermédiaires pour que l'ensemble de l'embout puisse se déformer sous le poids de l'utilisateur.As we know, the slats are kept on the frame of a box spring by end caps of particular profile, which are in some cases made of elastomeric material, and in which alternate elastic supports and intermediate hollow spaces so that the entire tip may deform under the weight of the user.

Dans d'autres réalisations, les embouts sont réalisés en matière plastique semi-rigide, beaucoup plus difficilement déformables. Dans ce cas ce sont les lattes elles-mêmes qui confèrent au sommier l'élasticité demandée.In other embodiments, the tips are made of semi-rigid plastic, much more hardly deformable. In this case it is the slats themselves which give the box spring the required elasticity.

En fait, quelle que soit la nature et la forme des embouts utilisés, la déformation des lattes est plus forte dans les zones où s'exercent des pressions plus importantes, par exemple au niveau du buste et des épaules. Il serait évidemment souhaitable de pouvoir modifier, au gré de l'utilisateur, la souplesse de chacune des lattes en fonction du poids ou du confort recherché. On connaít certes, la possibilité d'introduire un raidisseur amovible dans les embouts élastomères mais cela n'est pas valable, bien entendu, avec des embouts rigides.In fact, whatever the nature and form of end caps used, the deformation of the slats is greater in areas where there is greater pressure, for example at the bust and shoulders. It would be obviously desirable to be able to modify, at the option of the user, the flexibility of each slat in depending on the desired weight or comfort. We know certainly the possibility of introducing a removable stiffener in the elastomeric tips but this is not valid, of course, with rigid tips.

L'invention apporte une solution intéressante à ce problème en proposant un raidisseur adaptable à chaque latte ou chaque groupe de lattes qui seraient engagées dans n'importe quel type d'embout de fixation au cadre du sommier. Ce raidisseur universel peut être monté sur tous types de lattes, de toute nature, forme ou dimensions. Il présente en outre l'avantage d'être facilement accessible et manoeuvrable par l'usager qui peut ainsi régler à souhait, la rigidité de chacune des lattes-support.The invention provides an interesting solution to this problem by proposing a stiffener adaptable to each slat or each group of slats that would be engaged in any type of attachment to the frame of the bedspring. This universal stiffener can be mounted on all types of slats, of any kind, shape or size. he also has the advantage of being easily accessible and maneuverable by the user who can adjust as desired, the rigidity of each of the support slats.

L'invention a donc pour objet un raidisseur pour sommier à lattes constitué par une tige ayant une section dissymétrique qui s'étend longitudinalement sous au moins une latte et qui est montée de façon à pouvoir pivoter, dans un talon rapporté sous la partie centrale de la latte, ainsi que dans des organes de guidage fixés aux extrémités de la latte.The invention therefore relates to a stiffener for slatted base consisting of a rod having a section asymmetrical which extends longitudinally under at least a slat and which is mounted so that it can pivot, in a heel added under the central part of the slat, as well that in guide members attached to the ends of the latte.

Selon une forme de réalisation préférée de l'invention, la tige est un jonc ayant un profil en double T, qui est enchassée dans un disque pouvant tourner, dans un palier de guidage formé dans le talon, ainsi que dans un disque pivotant, prévu dans chaque organe de guidage. Plus précisément les organes de guidage sont des pièces qui enserrent la latte et sont prépositionnés à proximité de l'extrémité de la latte.According to a preferred embodiment of the invention, the rod is a rod having a duplicate profile T, which is encased in a rotatable disc, in a guide bearing formed in the heel, as well as in a pivoting disc, provided in each guide member. More precisely the guide members are parts which enclose the batten and are prepositioned near the end of the batten.

En variante de réalisation les organes de guidage sont formés dans les embouts de fixation de la latte au cadre du sommier.As an alternative embodiment, the guide members are formed in the end pieces for fixing the batten to the box frame.

Des caractéristiques particulières et avantages de l'invention ressortiront de la description qui va suivre d'un exemple particulier de réalisation dans lequel il est fait référence aux dessins annexés qui représentent.Special features and advantages of the invention will emerge from the description which follows of a particular example of embodiment in which it is refers to the accompanying drawings which show.

Figure 1, une vue en perspective d'une latte de sommier équipée de son raidisseur.Figure 1, a perspective view of a slat box spring equipped with its stiffener.

Figure 2, une vue en coupe du jonc raidisseur selon la figure 1.Figure 2, a sectional view of the stiffening rod according to figure 1.

Figure 3, une vue analogue à la figure 1 montrant le jonc raidisseur dans une position de résistance maximum.Figure 3, a view similar to Figure 1 showing the stiffening rod in a position of maximum resistance.

On a représenté à la figure 1 une latte 1 de sommier dont on sait que les extrémités sont engagées dans un embout non représenté, lui-même fixé sur la cadre du sommier. La latte est relativement flexible par elle-même, et légèrement cintrée vers le haut.There is shown in Figure 1 a slat 1 of box spring, the ends of which are known to be engaged in a nozzle not shown, itself fixed on the frame of the bedspring. The slat is relatively flexible by itself, and slightly curved upwards.

Sous la partie centrale de la latte est rapporté un talon 2 percé d'une ouverture 3 dans le sens de la latte, l'ouverture faisant office de palier de guidage pour un jonc profilé 4 qui constitue le raidisseur de la latte.Under the central part of the batten is attached a heel 2 pierced with an opening 3 in the direction of the slat, the opening acting as a guide bearing for a rod section 4 which constitutes the stiffener of the batten.

Ce jonc 4 montré à la figure 2, présente une section ayant un profil en double T, avantageusement réalisé en métal ou en matière plastique et il est donc relativement flexible perpendiculairement à sa plage centrale. Le jonc 4 est enchassé dans un disque 5 susceptible de tourner dans le palier de guidage central 3. Le jonc s'étend ainsi tout le long de la latte 1 et chacune de ses extrémités est introduite dans un organe de guidage 6 faisant également office de palier pour recevoir un disque d'extrémité pivotant 7. On voit que l'organe de guidage 6 enserre la latte 1. Il est, au montage, prépositionné à proximité du bout de la latte. En variante de réalisation non représentée, c'est l'embout de fixation de la latte au cadre qui pourrait être lui-même creusé d'une alvéole pour loger le raidisseur.This rod 4 shown in Figure 2, has a section having a double T profile, advantageously made made of metal or plastic and so it's relatively flexible perpendicular to its central range. The rush 4 is encased in a disc 5 likely to turn in the central guide bearing 3. The rod thus extends all along batten 1 and each of its ends is introduced into a guide member 6 also making bearing office to receive an end disc pivoting 7. It can be seen that the guide member 6 encloses the batten 1. It is prepositioned near the end of the batten. As an alternative embodiment shown, it is the end piece for fixing the slat to the frame which could itself be dug from a cell to accommodate the stiffener.

On voit que dans la position représentée à la figure 1, la partie centrale plus mince du jonc est sensiblement parallèle à la latte. Si on exerce dans le sens des flèches une pression sur cette latte dont les extrémités ainsi que les organes de guidage 6 sont maintenus par le cadre du sommier, la flexion de la latte se transmettra par le talon 2 au jonc 4 qui n'oppose dans la position représentée pratiquement aucune résistance à cette flexion.We see that in the position shown in the Figure 1, the thinner central part of the rod is substantially parallel to the slat. If we exercise in the direction arrows pressing on this slat whose ends as well as the guide members 6 are held by the frame of the box spring, the bending of the slat will be transmitted by heel 2 to bangle 4 which does not oppose in the position shown practically no resistance to this bending.

L'utilisateur est en mesure de faire pivoter aisément le jonc dans ses paliers 3, 6 soit directement soit à l'aide d'un levier de commande non représenté. Une rotation de 90° amènera le jonc 4 dans la position illustrée à la figure 3, position dans laquelle la plage centrale du profil à double T est perpendiculaire au plan de la latte. On comprend que dans cette position le jonc 4 joue son rôle de raidisseur et oppose à une pression exercée sur la latte 4 dans le sens des flèches, une résistance maximum. Entre les deux positions extrêmes illustrées aux figures 1 et 3, l'utilisateur dispose de positions intermédiaires possibles et peut orienter plus ou moins le jonc par rapport au plan de la latte en faisant varier ainsi l'efficacité du raidisseur et par conséquent la rigidité ou la souplesse de la latte.User is able to rotate easily the rod in its bearings 3, 6 either directly or using a control lever not shown. A 90 ° rotation will bring rod 4 into position illustrated in figure 3, position in which the range center of the double T profile is perpendicular to the plane of the latte. We understand that in this position the rod 4 plays its role of stiffener and opposes a pressure exerted on batten 4 in the direction of the arrows, maximum resistance. Between the two extreme positions illustrated in Figures 1 and 3, the user has intermediate positions possible and can orient the rod more or less relative to in terms of the batten, thus varying the efficiency of the stiffener and therefore the stiffness or flexibility of the latte.

Le jonc raidisseur présenté sur les figures a un profil simple qui correspond à des pièces aisément obtenues dans le commerce. Ce raidisseur pourrait être réalisé en toute matière et avoir un profil différent de celui-là dès l'instant où il se présenterait comme une tige ayant une section dissymétrique et où il aurait donc un module d'inertie variable selon l'orientation qu'on lui donne par rapport à la latte.The stiffening rod shown in the figures has a simple profile which corresponds to easily obtained parts in trade. This stiffener could be made in any material and have a different profile from that one as soon the instant it would appear as a rod having a asymmetrical section and where it would therefore have a module variable inertia depending on the orientation given by compared to the slat.
