Abstract

The slatted mattress base has two cursors (6) that slide on a deformable and adjustable rod (4). This extends longitudinally under a slat (1) and its ends are free. The rod can pivot in the cursors and in a heel (2) fixed under the center of the slat. The rod is a double T in cross section and is held in pivoting discs (5,7) in the heel and the cursors.

Description

L'invention se situe dans le domaine technique des sommiers à lattes et elle se rapporte à un dispositif d'ajustement variable de leur souplesse.The invention lies in the technical field of slatted bed bases and it relates to a device variable adjustment of their flexibility.

Les lattes servant à supporter un matelas sont comme on 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.The slats used to support a mattress are as we know, held 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 can deform under the user weight.

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'élasticite 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 requested 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.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 depending the desired weight or comfort.

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.We certainly know the possibility of introducing a removable stiffener in the elastomer ends but this is not valid, of course, with rigid tips.

Pour les sommiers à plusieurs lattes superposées ou disposées par groupe les unes à côté des autres, une solution consiste à déplacer des curseurs sur les lattes de façon à les solidariser ensemble ponctuellement. Ainsi selon l'emplacement des curseurs aux extrémités ou au centre, on renforce la rigidité des lattes ou au contraire on l'atténue.For box springs with several overlapping slats or arranged in groups next to each other, one solution is to move sliders on the slats of so as to join them together punctually. So according to the location of the sliders at the ends or in the center, reinforces the rigidity of the slats or on the contrary attenuates it.

Cependant quand on veut modifier fréquemment la souplesse de certaines lattes, il n'est pas très pratique d'effectuer ces manipulations qui ne sont possibles qu'en soulevant le matelas.However when you want to change the flexibility of some slats, it is not very practical to carry out these manipulations which are only possible in lifting the mattress.

L'invention résout ce problème en associant à ce dispositif de réglage à curseurs, connu en soi, un système de raidisseur facilement accessible par l'usager, qui avec les curseurs autorisent le réglage de la souplesse d'un sommier dans une très large gamme de possibilités.The invention solves this problem by associating with this slider adjustment device, known per se, a system stiffener easily accessible by the user, which with the sliders allow the flexibility of a box spring in a very wide range of possibilities.

L'invention a donc pour objet un dispositif d'ajustement variable de la souplesse d'un sommier à lattes comportant au moins deux curseurs déplaçables associés à une latte ou à un groupe de lattes, dispositif selon lequel lesdits curseurs coulissent aussi sur au moins un raidisseur disposé sous les lattes, raidisseur dont les extrémités sont libres sans autre point d'appui sur une partie fixe du sommier, le raidisseur étant constitué d'une tige déformable et réglable.The subject of the invention is therefore a device variable adjustment of the flexibility of a slatted base comprising at least two movable sliders associated with a slat or a group of slats, device according to which said sliders also slide on at least one stiffener placed under the slats, stiffener whose ends are free without any other support point on a fixed part of the box spring, the stiffener consisting of a deformable rod and adjustable.

Plus généralement le raidisseur est 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 les curseurs déplaçables.More generally, the stiffener is a rod having an asymmetrical section which extends longitudinally under at least one batten which is mounted so that it can pivot in a heel fitted under the central part of the batten, as well as in the movable sliders.

Selon une forme particulière de réalisation de l'invention, le raidisseur est un jonc ayant un profil en double T qui est enchâssé dans un disque pouvant tourner dans un palier de guidage formé dans le talon, ainsi que dans un disque pivotant prévu dans chaque curseur.According to a particular embodiment of the invention, the stiffener is a rod having a profile in double T which is embedded in a rotatable disc in a guide bearing formed in the heel, as well as in a swivel disc provided in each slider.

Les caractéristiques particulières de l'invention et les avantages qu'elle procure, ressortiront de la description qui va suivre d'exemples non limitatifs de réalisation dans lesquels il est fait référence aux dessins annexés qui représentent

  • figure 1, une vue en perspective de deux lattes de sommier équipées d'un raidisseur,
  • figure 2, une vue en coupe du jonc raidisseur selon la figure 1,
  • figure 3, une vue en élévation d'un curseur déplaçable,
  • figure 4, une vue analogue à la figure 1 montrant les curseurs déplacés en position centrale,
  • figures 5 et 6, des vues équivalentes aux figures 1 et 4, mais avec le jonc raidisseur en position de résistance maximum,
  • figure 7, une variante de réalisation de la figure 4 mais avec une seule latte.
  • The particular features of the invention and the advantages which it provides will emerge from the following description of nonlimiting exemplary embodiments in which reference is made to the appended drawings which represent
  • FIG. 1, a perspective view of two bed slats fitted with a stiffener,
  • FIG. 2, a sectional view of the stiffening rod according to FIG. 1,
  • FIG. 3, an elevation view of a movable cursor,
  • FIG. 4, a view similar to FIG. 1 showing the sliders moved to the central position,
  • FIGS. 5 and 6, views equivalent to FIGS. 1 and 4, but with the stiffening rod in the position of maximum resistance,
  • Figure 7, an alternative embodiment of Figure 4 but with a single slat.
  • La figure 1 montre un groupe de deux lattes 1 de sommier disposées côte à côte dont les bouts sont engagés dans un même embout d'extrémité à double alvéole non représenté lui-même fixé sur le cadre du sommier. Les lattes sont légèrement flexibles et cintrées vers le haut. Sur les lattes, peuvent coulisser deux curseurs 6 qui les enserrent de façon connue comme le montre la figure. A la figure 1 les curseurs sont placés à proximité des extrémités des lattes.Figure 1 shows a group of two slats 1 of box spring arranged side by side with the ends engaged in the same end cap with double cell not represented himself fixed on the frame of the box spring. The slats are slightly flexible and bent upwards. On the slats, can slide two sliders 6 which enclose them in a known manner as shown in the figure. In Figure 1 the sliders are placed near the ends of the slats.

    Sous leur partie centrale est rapporté un talon 2, percé d'une ouverture 3 dans le sens des lattes, l'ouverture faisant office de palier de guidage pour un jonc profilé 4 qui constitue le raidisseur complémentaire des lattes.Under their central part is reported a heel 2, pierced with an opening 3 in the direction of the slats, the opening acting as a guide bearing for a profiled rod 4 which constitutes the complementary stiffener of the slats.

    Le jonc 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.The ring shown in Figure 2 has a section having a double T profile, advantageously made of metal or plastic, and so it's relatively flexible perpendicular to its central range.

    Le jonc 4 est enchâssé dans un disque 5 susceptible de tourner dans le palier de guidage central 3. Le jonc s'étend ainsi tout le long des lattes 1, au dessous de l'espace longitudinal séparant les deux lattes.The rod 4 is embedded in a disc 5 likely to rotate in the central guide bearing 3. The rod thus extends all along the slats 1, below of the longitudinal space separating the two slats.

    Chaque curseur 6 montré à la figure 3 fait également office de palier pour recevoir un disque pivotant 7 pourvu d'une ouverture ayant le profil du jonc 4. Ainsi ce dernier peut coulisser librement dans chaque disque.Each cursor 6 shown in Figure 3 is also as a bearing to receive a swivel disc 7 provided with an opening having the profile of the rod 4. Thus this the latter can slide freely in each disc.

    On voit que dans la position représentée à la figure 1, la partie centrale plus mince du jonc est sensiblement parallèle à la latte. Les curseurs 6 sont à proximité des extrémités des lattes. Si on exerce une pression sur les lattes, dans le sens des flèches, leur flexion se transmettra par le talon 2 au jonc 4. Ce dernier, bloqué en extrémité par les curseurs n'opposera à la flexion des lattes que sa résistance propre, dans cette orientation où il est parallèle aux lattes, c'est-à-dire une résistance limitée. We see that in the position shown in the Figure 1, the thinner central part of the rod is substantially parallel to the slat. Cursors 6 are at near the ends of the slats. If we exercise a pressure on the slats, in the direction of the arrows, their bending will be transmitted by the heel 2 to the rod 4. The latter, blocked at the end by the sliders will not prevent bending slats as its own resistance, in this orientation where it is parallel to the slats, that is to say a resistance limited.

    Cette résistance sera pratiquement nulle dans le cas où les extrémités du jonc seraient libres et non bloquées par les curseurs. C'est le cas de la figure 4 ou les deux curseurs 6 ont été ramenés au milieu des lattes, contre le talon 2. La résistance propre du jonc n'intervient que sur la courte longueur qui sépare les deux curseurs rapprochés, les extrémités du jonc étant libres ; on est ici en position de souplesse maximum.This resistance will be practically zero in the case the ends of the rod are free and not blocked by the sliders. This is the case in Figure 4 or the two sliders 6 have been brought back to the middle of the slats, against the heel 2. The ring's own resistance is not involved only on the short length that separates the two sliders close together, the ends of the rod being free; we are here in a position of maximum flexibility.

    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.User is able to rotate easily the rod in its bearings (3, 6) either directly, either using a control lever not shown.

    Une rotation de 90° amènera le jonc 4 dans la position illustrée à la figure 5, position dans laquelle la plage centrale du profil à double T est perpendiculaire au plan de la latte, et ou les deux curseurs sont aux extrémités des lattes. On voit que dans cette position les extrémités du jonc 4 sont en appui sur les curseurs écartés ; le jonc joue son rôle de raidisseur sur toute sa longueur et oppose ainsi au fléchissement des lattes une résistance maximum. Si l'on rapproche les curseurs 6 l'un de l'autre, la longueur efficace du jonc 4 diminue d'autant et dans la position de la figure 6 où les deux curseurs sont rapprochés (comme dans le cas de la figure 4), la résistance à la flexion est limitée à la résistance qu'oppose le jonc sur la courte longueur qui sépare les deux curseurs.A 90 ° rotation will bring rod 4 into the position illustrated in FIG. 5, position in which the central range of the double-T profile is perpendicular to the plane of the slat, and where the two sliders are ends of the slats. We see that in this position the ends of the rod 4 are supported on the sliders dismissed; the rod plays its role of stiffener throughout its length and thus opposes the deflection of the slats a maximum resistance. If we compare the cursors 6 one of the other, the effective length of the rod 4 decreases accordingly and in the position of figure 6 where the two sliders are close together (as in Figure 4), the resistance bending is limited to the resistance offered by the rod on the short length that separates the two sliders.

    L'utilisateur dispose ainsi d'une gamme étendue de possibilités de réglage de la souplesse du sommier, soit en orientant le jonc par rapport au plan des lattes pour faire varier l'efficacité du raidisseur, soit en déplaçant les curseurs sur les lattes pour faire varier les points d'appui du raidisseur, soit les deux possibilités.The user thus has a wide range of possibilities for adjusting the flexibility of the box spring, either orienting the rod relative to the plane of the slats to make vary the efficiency of the stiffener, either by moving the sliders on the slats to vary the support points of the stiffener, that is the two possibilities.

    Le dispositif décrit est utilisable avec une seule latte comme le montre la figure 7, où l'on voit deux curseurs 6 en position centrale, encadrant le talon 2, le jonc 4 étant en position parallèle à la latte. On est ainsi dans une position de souplesse maximum.The device described can be used with a single batten as shown in Figure 7, where we see two sliders 6 in the central position, framing the heel 2, the rod 4 being in position parallel to the batten. We are like this in a position of maximum flexibility.

    En variante de réalisation non représentée, on pourrait utiliser un jonc de profil différent par exemple une tige ayant une section dissymétrique.As an alternative embodiment not shown, could use a different profile rod for example a rod having an asymmetrical section.

    On pourrait aussi n'utiliser qu'une tige déformable et réglable, le réglage de souplesse étant alors assuré essentiellement par la position des curseurs.We could also use only one rod deformable and adjustable, the flexibility setting then being mainly ensured by the position of the sliders.

    Dans tous les cas il importe que la pièce qui constitue le raidisseur inférieur, placé sous la ou les lattes, soit libre à ses extrémités de part et d'autre des curseurs mobiles, c'est-à-dire sans autre point d'appui sur une partie fixe.In all cases it is important that the part which constitutes the lower stiffener, placed under the slats, be free at its ends on either side of mobile cursors, that is to say without other fulcrum on a fixed part.
