Description

SUSPENSION POUR UN SOMMIER DU TYPE MULTI-ÉLÉMENTSSUSPENSION FOR A MULTI-ELEMENT-TYPE BED
La présente invention concerne une suspension prise en tant qu'élément constitutif d'un sommier du type multi-éléments.The present invention relates to a suspension taken as a constituent element of a multi-element type box spring.
Ce type de sommier, décrit par exemple dans le document WO- 98/11806, constitue une alternative aux sommiers à lattes ; il permet notamment de moduler l'élasticité de façon ponctuelle par zones, afin d'offrir un meilleur confort à l'utilisateur.This type of box spring, described for example in document WO-98/11806, constitutes an alternative to slatted bed bases; it allows in particular to modulate the elasticity in a punctual way by zones, in order to offer a better comfort to the user.
D'autres documents montrent des suspensions multi-éléments, comme le brevet EP-653 174. Généralement, ces suspensions ont une capacité de déformation préétablie qui dépend du matériau utilisé et de la forme des parties souples par exemple.Other documents show multi-element suspensions, such as patent EP-653 174. Generally, these suspensions have a predetermined deformation capacity which depends on the material used and on the shape of the flexible parts for example.
La présente invention propose, comme dans le cas du document EP précité, une suspension réalisée en matériau thermoplastique, dont les parties souples s'apparentent à celles dont il est question dans le document WO précité.The present invention provides, as in the case of the aforementioned EP document, a suspension made of thermoplastic material, the flexible parts of which are similar to those mentioned in the aforementioned WO document.
Cette suspension selon l'invention offre en plus, de multiples possibilités pour faire varier sa propre élasticité et ainsi l'adapter en fonction des besoins c'est-à-dire en fonction de sa position sur le sommier et de la charge qui est susceptible de lui être appliquée.This suspension according to the invention also offers multiple possibilities for varying its own elasticity and thus adapting it as required, that is to say as a function of its position on the bed base and of the load which is liable to be applied to it.
De plus, cette suspension présente l'avantage de se monter facilement et rapidement sur les traverses du sommier.In addition, this suspension has the advantage of being easily and quickly mounted on the cross beams.
La suspension selon l'invention comprend des moyens de solidarisation qui coopèrent avec les traverses porteuses du cadre du sommier et, entre ces moyens et le plateau servant de support pour le matelas, une structure monobloc constituée d'une paire de lames de ressort en forme d'arc de cercle, disposées symétriquement par rapport à un plan parallèle auxdites traverses, et dont les extrémités sont reliées par une sorte de charnière monobloc réalisée en forme de tube fendu, lesquelles charnières étant susceptibles d'accueillir et/ou de coopérer avec des organes complémentaires qui se logent dans l'orifice dudit tube et permettent de faire varier la capacité de déformation de ladite structure dans des proportions importantes.The suspension according to the invention comprises securing means which cooperate with the supporting crosspieces of the frame of the bed base and, between these means and the plate serving as support for the mattress, a monobloc structure constituted by a pair of shaped spring blades of an arc of a circle, arranged symmetrically with respect to a plane parallel to said crosspieces, and the ends of which are connected by a kind of one-piece hinge produced in the form of a split tube, which hinges being capable of receiving and / or cooperating with complementary organs that lodge in the orifice of said tube and make it possible to vary the deformation capacity of said structure in significant proportions.
Selon une autre disposition de l'invention, les charnières aménagées à l'extrémité des lames comportent des fentes orientées l'une vers l'autre c'est-à- dire vers l'intérieur de la structure, l'orifice dudit tube étant susceptible d'accueillir au moins une pièce qui modifie la capacité de déformation desdites lames lorsqu'une contrainte est appliquée sur le plateau.According to another arrangement of the invention, the hinges fitted at the end of the blades have slots oriented towards each other, that is to say towards the inside of the structure, the orifice of said tube being capable of accommodating at least one part which modifies the deformation capacity of said blades when a stress is applied to the plate.
Selon une première possibilité de l'invention, les pièces insérables dans les orifices des tubes charnières se présentent sous la forme de chevilles cylindriques ; elles sont réalisées en matériau dont la dureté est choisie selon la déformation souhaitée pour la structure, un matériau du genre polypropylène pour une grande rigidité ou du caoutchouc ou similaire pour une certaine souplesse.According to a first possibility of the invention, the parts insertable into the orifices of the hinge tubes are in the form of cylindrical dowels; they are made of material whose hardness is chosen according to the deformation desired for the structure, a material of the polypropylene type for high rigidity or rubber or the like for a certain flexibility.
Selon une autre disposition de l'invention, les chevilles insérables dans chaque charnière peuvent avoir une longueur de l'ordre de la moitié de celle de la charnière et comporter une tête dont l'encombrement est supérieur à celui de ladite charnière, en matériau souple, faisant office de tampon amortisseur et d'atténuateur de bruit lorsque le plateau, dans ses mouvements, vient prendre appui sur ladite tête. Selon une autre disposition de l'invention, les chevilles insérables dans les orifices tubulaires des charnières sont reliées entre elles par une bande et forment une sorte de tendeur-raidisseur, laquelle bande est réalisée en matériau choisi selon le type de déformation souhaité : caoutchouc de dureté variable ou polypropylène pour réaliser une structure rigide, laquelle bande peut aussi comporter une section évolutive entre les chevilles, soit par ses dimensions, soit par des réductions de matière au moyen de trous.According to another arrangement of the invention, the plugs insertable into each hinge can have a length of the order of half that of the hinge and include a head whose size is greater than that of said hinge, made of flexible material , acting as a damping buffer and attenuator of noise when the plate, in its movements, comes to bear on said head. According to another arrangement of the invention, the plugs which can be inserted into the tubular orifices of the hinges are connected to one another by a strip and form a kind of tensioner-stiffener, which strip is made of material chosen according to the type of deformation desired: rubber of variable hardness or polypropylene to produce a rigid structure, which strip may also have an evolving section between the pins, either by its dimensions or by material reductions by means of holes.
Selon une variante de réalisation, la pièce insérable formant tendeur- raidisseur, se présente sous la forme d'une bande fendue en Vé à ses extrémités, lesquelles extrémités comportent chacune une petite cheville cylindrique insérable dans la charnière correspondante. Selon une autre disposition de l'invention, les petites chevilles comportent sur le côté de la bande, une tête servant d'arrêt contre les flancs de la charnière correspondante, laquelle tête peut également faire office de tampon amortisseur pour le plateau. Selon un autre mode de réalisation, les charnières sont ouvertes sur l'extérieur des lames de ressort, de façon à accueillir un tendeur-raidisseur en forme de bracelet pouvant comporter à ses extrémités, côtés charnières, des tampons amortisseurs en saillie, pour le contact avec le plateau.According to an alternative embodiment, the insertable piece forming a tensioner-stiffener is in the form of a split V-shaped band at its ends, which ends each have a small cylindrical dowel insertable in the corresponding hinge. According to another arrangement of the invention, the small pegs have on the side of the strip, a head serving as a stop against the sides of the corresponding hinge, which head can also act as a shock absorbing pad for the plate. According to another embodiment, the hinges are open on the outside of the spring blades, so as to accommodate a tensioner-stiffener in the form of a bracelet which may have, at its ends, hinge sides, projecting damping pads, for contact with the tray.
Selon une variante, les charnières ouvertes sur l'extérieur comportent également dans leur portion de paroi tubulaire, une fente en forme de lumière tournée vers l'intérieur des lames de ressort, laquelle fente permet le montage d'un tendeur-raidisseur constitué d'une cheville insérable dans la charnière correspondante et d'une lame dont la largeur correspond à celle de ladite lumière. L'invention concerne également les pièces complémentaires qui coopèrent avec les charnières et en particulier les tendeurs-raidisseurs constitués soit d'un bracelet, soit d'une bande centrale réalisée en matériau choisi selon la capacité de déformation souhaitée en allongement, lesquels tendeurs-raidisseurs peuvent comporter, à leurs extrémités côtés charnières, des aménagements faisant office de tampon amortisseur.According to a variant, the hinges open to the outside also have, in their portion of tubular wall, a slot in the form of a light turned towards the inside of the spring blades, which slot allows the mounting of a tensioner-stiffener consisting of a dowel insertable in the corresponding hinge and a blade whose width corresponds to that of said lumen. The invention also relates to the complementary parts which cooperate with the hinges and in particular the tensioners-stiffeners consisting either of a bracelet or of a central strip made of material chosen according to the desired deformation capacity in elongation, which tensioners-stiffeners may include, at their ends on the hinge sides, arrangements acting as a shock absorbing pad.
Toujours selon l'invention, les moyens de solidarisation de la suspension sur la traverse sont constitués d'une mâchoire en forme de clip qui enserre latéralement les bords de ladite traverse.Still according to the invention, the means for securing the suspension to the crosspiece consist of a clip-shaped jaw which laterally encloses the edges of said crosspiece.
Toujours selon l'invention, le verrouillage de la suspension sur la traverse s'effectue au moyen d'un ergot disposé au centre du clip, lequel ergot est destiné à s'insérer dans un orifice aménagé sur la face supérieure de ladite traverse.Still according to the invention, the suspension is locked on the cross member by means of a lug arranged in the center of the clip, which lug is intended to be inserted in an orifice provided on the upper face of said cross member.
Selon une autre disposition de l'invention, le plateau support du matelas se présente sous la forme d'une plaque ajourée, personnalisable avec, dans sa partie centrale, une petite traverse susceptible d'être insérée dans une mâchoire en forme de clip aménagée sur le dessus de la structure élastique, de façon monobloc, l'ensemble étant réalisé en caoutchouc thermoplastique à haute mémoire élastique du genre TPEE comme par exemple le matériau connu sous la dénomination commerciale « Hytrel ».According to another arrangement of the invention, the mattress support plate is in the form of a perforated plate, customizable with, in its central part, a small crosspiece capable of being inserted in a jaw in the form of a clip arranged on the top of the elastic structure, in one piece, the assembly being made of thermoplastic rubber with high elastic memory of the TPEE type, for example the material known under the trade name "Hytrel".
Selon une variante de réalisation de l'invention, le plateau support du matelas disposé au-dessus de la structure, est monobloc avec cette dernière et le clip de fixation et l'ensemble sont réalisés également en caoutchouc thermoplastique.According to an alternative embodiment of the invention, the mattress support plate disposed above the structure, is in one piece with the latter and the fixing clip and the assembly are also made of thermoplastic rubber.

La suspension 1 comprend : - des moyens qui permettent sa fixation sur la traverse 2 et en particulier une mâchoire 3 en forme de clip, - des moyens pour fixer un plateau 4 qui sert de support au matelas non représenté, et, entre les deux, - une structure 5, déformable élastiquement.The suspension 1 comprises: - means which allow it to be fixed to the cross-member 2 and in particular a jaw 3 in the form of a clip, - means for fixing a plate 4 which serves to support the mattress not shown, and, in between, - a structure 5, elastically deformable.
Cette suspension forme de préférence un ensemble monobloc, obtenu par moulage ; elle est réalisée en caoutchouc thermoplastique à haute mémoire élastique du genre TPEE comme par exemple en matériau connu sous la dénomination commerciale « Hytrel ».This suspension preferably forms a one-piece assembly, obtained by molding; it is made of thermoplastic rubber with high elastic memory of the TPEE type, for example of a material known under the trade name "Hytrel".
Pour un sommier classique de faible largeur, pour une personne, on peut utiliser environ 60 suspensions réparties sur toute la surface et en particulier sur les traverses 2 qui constituent le fond dudit sommier. Dans l'exemple représenté sur les figures, on remarque que le plateau support 4 comporte des orifices 6 qui définissent une petite traverse 7. Cette traverse est prisonnière dans une autre mâchoire 9 en forme de clip également.For a conventional box spring of small width, for one person, about 60 suspensions can be used distributed over the entire surface and in particular on the crosspieces 2 which constitute the bottom of said box spring. In the example shown in the figures, it can be seen that the support plate 4 has orifices 6 which define a small cross-member 7. This cross-member is trapped in another jaw 9 also in the form of a clip.
Cependant, dans une variante de réalisation non représentée, le plateau peut être monobloc avec la suspension, l'ensemble étant moulé constituant une seule et même pièce.However, in a variant embodiment not shown, the plate can be in one piece with the suspension, the assembly being molded constituting a single piece.
La possibilité de dissocier le plateau 4 de la suspension permet une plus grande personnalisation des plateaux ainsi que des possibilités multiples en matière de décoration.The possibility of dissociating the plate 4 from the suspension allows greater personalization of the plates as well as multiple possibilities in terms of decoration.
A noter également que le plateau 4 peut être recouvert d'un chapeau non représenté, lui aussi en matériau divers du genre caoutchouc ou autre.It should also be noted that the plate 4 can be covered with a hat (not shown), also made of various material of the rubber or other type.
On remarque que les mâchoires 3 et 9, en forme de clip, comportent chacune respectivement une embase 31 , 91 et des côtés 32, 92 dont la section est de forme lunulaire, lesquels côtés se prolongent par des rebords 33 et 93 respectivement. Ces rebords 33 et 93 recouvrent pour l'un la traverse 2 et pour l'autre la petite traverse du plateau 4 sur quelques millimètres, 2 ou 3 mm, afin d'éviter tout échappement intempestif en cas de mouvement brusque du plateau 4 par exemple.It is noted that the jaws 3 and 9, in the form of a clip, each have a base 31, 91 and sides 32, 92 respectively, the section of which is of lunar shape, which sides are extended by flanges 33 and 93 respectively. These edges 33 and 93 cover for one the crosspiece 2 and for the other the small crosspiece of the plate 4 over a few millimeters, 2 or 3 mm, so avoid any untimely escape in the event of sudden movement of the plate 4 for example.
On remarque aussi que la mâchoire 3 comporte au centre de sa semelle 31 , un ergot 10. Cet ergot permet de verrouiller la position de la suspension sur la traverse 2, laquelle traverse comporte de place en place, des orifices 12 sur sa surface supérieure.We also note that the jaw 3 has in the center of its sole 31, a lug 10. This lug makes it possible to lock the position of the suspension on the cross member 2, which cross member comprises from place to place, orifices 12 on its upper surface.
La structure élastique 5 entre la mâchoire 3 et le plateau 4 se présente sous une forme ovale ou elliptique. Sur l'exemple représenté figures 1 et 2, cette structure est constituée de lames de ressort 13 en forme d'arc de cercle disposées symétriquement par rapport à un plan horizontal qui passe par les extrémités desdites lames, lesquelles extrémités sont en forme de charnières 14. Ces lames sont orientées transversalement par rapport à la traverse 2. Elles sont monobloc avec les mâchoires 3 et 9 ou avec le plateau 4 si ce dernier est monobloc, et s'étendent, par moitié, de part et d'autre de la partie centrale de l'embase desdites mâchoires.The elastic structure 5 between the jaw 3 and the plate 4 is in an oval or elliptical shape. In the example shown in Figures 1 and 2, this structure consists of spring blades 13 in the form of a circular arc arranged symmetrically with respect to a horizontal plane which passes through the ends of said blades, which ends are in the form of hinges 14 These blades are oriented transversely with respect to the cross member 2. They are in one piece with the jaws 3 and 9 or with the plate 4 if the latter is in one piece, and extend, in half, on either side of the part. central of the base of said jaws.
Les charnières 14 se présentent sous la forme de tubes fendus orientés parallèlement à la traverse 2. Figures 1 et 2, les fentes 15 sont orientées l'une vers l'autre vers l'intérieur de la structure 5 et sont situées dans le plan de symétrie de ladite structure. Les orifices cylindriques 16 de chaque charnière 14, peuvent accueillir comme représenté figure 1 , des organes complémentaires en forme de pièces cylindriques dont le diamètre est égal ou légèrement supérieur au diamètre desdits orifices 16. Ces pièces sont réalisées avec un matériau dont la nature est choisie en fonction de la déformation souhaitée au niveau des charnières 14.The hinges 14 are in the form of split tubes oriented parallel to the cross member 2. Figures 1 and 2, the slots 15 are oriented towards one another towards the inside of the structure 5 and are located in the plane of symmetry of said structure. The cylindrical orifices 16 of each hinge 14 can accommodate, as shown in FIG. 1, complementary members in the form of cylindrical parts whose diameter is equal to or slightly greater than the diameter of said orifices 16. These parts are made of a material of which the nature is chosen depending on the desired deformation at the hinges 14.
En effet, des pièces en matériau rigide du genre polypropylène, interdiront toute déformation de la charnière et auront pour effet de rigidifier la structure 5.Indeed, parts made of rigid polypropylene-type material will prevent any deformation of the hinge and will have the effect of stiffening the structure 5.
Des pièces en caoutchouc à dureté shore choisie selon les nécessités, permettront une déformation variable au niveau des charnières 14. Ces pièces peuvent se présenter comme montré figure 1 sous la forme de chevilles 20. Ces chevilles 20 peuvent avoir une longueur qui correspond à la moitié de la longueur des charnières 14. Ainsi on peut insérer deux chevillesRubber parts with shore hardness chosen according to requirements, will allow variable deformation at the hinges 14. These parts can be presented as shown in FIG. 1 in the form of pegs 20. These pegs 20 can have a length which corresponds to half the length of the hinges 14. Thus one can insert two pegs
20 dans chaque charnière ; lesquelles chevilles peuvent comporter chacune une tête 21 dont l'encombrement est supérieur à celui de la charnière 14, laquelle tête sert de butée pour le plateau 4 en cas de déformation importante de la structure par écrasement et compression totale des lames 13. Cette tête20 in each hinge; which pins may each include a head 21 whose size is greater than that of the hinge 14, which head serves as a stop for the plate 4 in the event of significant deformation of the structure by crushing and total compression of the blades 13. This head
21 permet également d'amortir et d'atténuer les bruits pouvant résulter d'un contact entre le plateau 4 et ladite tête, laquelle tête étant réalisée comme la cheville, en matériau du genre caoutchouc.21 also makes it possible to dampen and attenuate the noises which may result from contact between the plate 4 and said head, which head being made like the dowel, of rubber-like material.
La déformation de la structure 5 peut encore être contrôlée au moyen d'une sorte de tendeur-raidisseur 22 constitué d'une bande 23 qui s'étend entre deux chevilles 24 formant ensemble une pièce monobloc.The deformation of the structure 5 can also be controlled by means of a kind of tensioner-stiffener 22 consisting of a band 23 which extends between two pins 24 together forming a single piece.
Cette bande peut être réalisée en tout matériau approprié, rigide du genre polypropylène ou élastique en caoutchouc dont la dureté shore est choisie en fonction de la déformation souhaitée au niveau de la structure 5.This strip can be made of any suitable rigid material of the polypropylene or elastic rubber type, the shore hardness of which is chosen as a function of the desired deformation at the level of the structure 5.
Les chevilles 24 s'insèrent dans les charnières 14 et en particulier dans les orifices 16 et la bande passe par la fente 15 aménagée au niveau de ces charnières 14. Là encore, cette pièce complémentaire en forme de tendeur-raidisseurThe pins 24 are inserted in the hinges 14 and in particular in the orifices 16 and the strip passes through the slot 15 arranged at the level of these hinges 14. Again, this complementary piece in the form of a tensioner-stiffener
22 peut être personnalisée avec des coloris adéquats.22 can be personalized with suitable colors.
Cette personnalisation peut aussi se retrouver sur les têtes 21 des chevilles 20 dont il était question précédemment.This personalization can also be found on the heads 21 of the pegs 20 which were discussed above.
Cette personnalisation dont il a également été question pour le plateau support 4 permet d'offrir un produit attractif aux multiples possibilités pour, en finale, offrir le meilleur confort possible.This customization, which was also discussed for the support plate 4, makes it possible to offer an attractive product with multiple possibilities, in the end, offering the best possible comfort.
Le plateau 4 peut être réalisé en bois, plastique, etc ...The plate 4 can be made of wood, plastic, etc.
La figure 3 montre une variante de réalisation du tendeur-raidisseur 22.FIG. 3 shows an alternative embodiment of the tensioner-stiffener 22.
La bande 23 de ce tendeur peut être aménagée avec par exemple une section décroissante entre les chevilles d'extrémités 24. Elle peut également comporter des réductions de matière de façon à en modifier les caractéristiques élastiques. Cette réduction de matière peut consister comme représenté figure 3, en des orifices 25 qui forment des jours.The strip 23 of this tensioner can be fitted with, for example, a decreasing section between the end pegs 24. It can also include reductions in material so as to modify the characteristics thereof. elastic. This reduction in material can consist, as shown in FIG. 3, in orifices 25 which form days.
La figure 4 montre la suspension équipée du tendeur-raidisseur 22 représenté figure 3. Les chevilles 24 de ce tendeur sont insérées dans les orifices tubulaires 16 des charnières 14. Lorsqu'une charge est appliquée sur le plateau 4, les lames de ressort 13 se déforment ; elles tendent à éloigner les charnières 14 l'une de l'autre et à refermer les fentes 15 des orifices 16. Une tension s'exerce sur la bande centrale 23 des tendeurs et cette tension contrarie le mouvement des lames de ressort 13. La figure 5 montre une autre variante de réalisation du tendeur- raidisseur 22.Figure 4 shows the suspension fitted with the tensioner-stiffener 22 shown in Figure 3. The pins 24 of this tensioner are inserted into the tubular holes 16 of the hinges 14. When a load is applied to the plate 4, the spring leaves 13 distort; they tend to distance the hinges 14 from each other and to close the slots 15 of the orifices 16. A tension is exerted on the central strip 23 of the tensioners and this tension counteracts the movement of the spring blades 13. The figure 5 shows another alternative embodiment of the tensioner-stiffener 22.
La bande centrale 23 est fendue à ses extrémités sous forme de Vé et elle se présente avec une allure générale de X. Les chevilles 24 se présentent sous la forme de petites chevilles 241 associées chacune à l'extrémité des portions de bandes 231. Chaque petite cheville 241 peut comporter une tète 27 qui se positionne, comme représenté figure 6, sur les flancs des charnières 14. Ces têtes 27 évitent tout mouvement du tendeur-raidisseur 22 dans les logements 16 des charnières 14 et en particulier tout mouvement qui tend à désolidariser lesdits tendeurs 22 desdits orifices 16. La mise en place du tendeur 22 selon le mode de réalisation de la figureThe central strip 23 is split at its ends in the form of a V and it has a general appearance of X. The pegs 24 are in the form of small pegs 241 each associated with the end of the portions of strips 231. Each small ankle 241 may include a head 27 which is positioned, as shown in FIG. 6, on the sides of the hinges 14. These heads 27 prevent any movement of the tensioner-stiffener 22 in the housings 16 of the hinges 14 and in particular any movement which tends to dissociate said tensioners 22 of said orifices 16. The positioning of the tensioner 22 according to the embodiment of the figure
5, s'effectue en insérant chacune des petites chevilles 241 par l'extérieur, dans les orifices 16 des charnières 14.5, is carried out by inserting each of the small pegs 241 from the outside, in the orifices 16 of the hinges 14.
La fente 26 aux extrémités de la bande 23 est suffisamment profonde pour permettre une déformation du tendeur et l'intégration des petites chevilles 241 dans leur logement.The slot 26 at the ends of the strip 23 is deep enough to allow deformation of the tensioner and the integration of the small pins 241 in their housing.
La figure 6 montre la suspension équipée du tendeur-raidisseur 22 représenté figure 5. Ce tendeur-raidisseur se centre et reste centré dans les charnières 14 grâce aux têtes 27 qui sont en appui sur les extrémités ou flancs desdites charnières. La figure 7 montre une variante de réalisation des charnières aménagées à l'extrémité des lames de ressort 13. Ces charnières 14' se présentent également sous la forme de tubes fendus. Les fentes 15' sont orientées vers l'extérieur. La portion de paroi tubulaire 30 de chaque charnière, se présente sous la forme d'un arc de cercle entre les extrémités des lames de ressort 13 ; cette paroi 30 est tournée vers l'intérieur. On remarque, figure 7, que la paroi 30 a une largeur inférieure à celle des lames de ressort 13. Les charnières 14' accueillent en fait un tendeur- raidisseur 22' en forme de bracelet. Ce bracelet est représenté figure 8, constitué d'un matériau du genre caoutchouc ; il comporte une section circulaire par exemple dont le diamètre correspond au diamètre des orifices cylindriques 16' aménagés au niveau de chacune desdites charnières 14'.Figure 6 shows the suspension equipped with the tensioner-stiffener 22 shown in Figure 5. This tensioner-stiffener is centered and remains centered in the hinges 14 thanks to the heads 27 which are supported on the ends or sides of said hinges. FIG. 7 shows an alternative embodiment of the hinges fitted at the end of the spring leaves 13. These hinges 14 ′ are also in the form of split tubes. The slots 15 'are oriented towards the outside. The tubular wall portion 30 of each hinge is in the form of an arc between the ends of the spring leaves 13; this wall 30 is turned inward. Note, in Figure 7, that the wall 30 has a width less than that of the spring blades 13. The hinges 14 'actually accommodate a tensioner-stiffener 22' in the form of a bracelet. This bracelet is shown in Figure 8, made of a rubber-like material; it has a circular section, for example, the diameter of which corresponds to the diameter of the cylindrical orifices 16 'arranged at each of said hinges 14'.
Le bracelet 22' est mis en place facilement dans les charnières 14' et s'intègre, comme représenté figure 9, dans l'encombrement général de la suspension grâce à la largeur de la paroi 30, qui est inférieure à celle des lames de ressort 13. Là encore, le matériau du bracelet 31 peut être adapté et choisi en fonction des caractéristiques souhaitées pour la suspension. De même la couleur du bracelet peut être choisie en fonction de la personnalisation prévue pour ces éléments de suspension.The strap 22 ′ is easily placed in the hinges 14 ′ and is integrated, as shown in FIG. 9, into the overall size of the suspension thanks to the width of the wall 30, which is less than that of the spring blades 13. Again, the material of the bracelet 31 can be adapted and chosen according to the characteristics desired for the suspension. Likewise, the color of the bracelet can be chosen according to the customization provided for these suspension elements.
La figure 10 montre une variante de réalisation du bracelet 22' qui consiste en une protubérance 31 située en saillie au niveau de chaque charnière 14'. Cette protubérance 31 épouse le contour extérieur des charnières 14' et ses extrémités 32 sont telles que, en cas de mouvement du plateau 4, ce dernier peut prendre appui sur lesdites extrémités supérieures 32 qui font office de tampon amortisseur et d'atténuateur de bruit. La figure 11 représente une variante de la figure 7 dans laquelle les charnières 14' sont ouvertes sur l'extérieur. La portion de paroi tubulaire 30' aux extrémités des lames 13 s'étend sur toute la largeur desdites lames 13 mais comporte une fente 35 en forme de lumière.Figure 10 shows an alternative embodiment of the bracelet 22 'which consists of a protrusion 31 located projecting at each hinge 14'. This protuberance 31 conforms to the external contour of the hinges 14 ′ and its ends 32 are such that, in the event of movement of the plate 4, the latter can bear on said upper ends 32 which act as a damping pad and a noise attenuator. Figure 11 shows a variant of Figure 7 in which the hinges 14 'are open to the outside. The tubular wall portion 30 'at the ends of the blades 13 extends over the entire width of said blades 13 but has a slot 35 in the form of a lumen.
Cette fente 35 permet d'insérer les extrémités d'un tendeur-raidisseur 22 particulier, représenté figure 12. Ce tendeur-raidisseur 22 comporte une bande centrale 23 et des chevilles 24 à ses extrémités. La bande centrale 23 a une largeur qui correspond à celle de la fente 35.This slot 35 makes it possible to insert the ends of a particular tensioner-stiffener 22, shown in FIG. 12. This tensioner-stiffener 22 comprises a strip central 23 and pegs 24 at its ends. The central strip 23 has a width which corresponds to that of the slot 35.
Ainsi, comme représenté figure 13, le tendeur-raidisseur 22 s'étend entre les parois 32 avec ses extrémités et en particulier les chevilles 24, logées dans les charnières 14'. Les chevilles 24 peuvent avoir une largeur inférieure ou égale à la largeur des charnières.Thus, as shown in Figure 13, the tensioner-stiffener 22 extends between the walls 32 with its ends and in particular the pins 24, housed in the hinges 14 '. The pins 24 may have a width less than or equal to the width of the hinges.
Ce type de tendeur-raidisseur 22, représenté figure 12, présente l'avantage d'être immobilisé et verrouillé au niveau des charnières 14'.This type of tensioner-stiffener 22, shown in Figure 12, has the advantage of being immobilized and locked at the hinges 14 '.
De la même façon, le bracelet 22' représenté figure 8, est inamovible lorsqu'il est positionné dans les charnières 14', quels que soient les mouvements imposés au plateau 4 et aux lames de ressort 13. In the same way, the bracelet 22 'shown in FIG. 8 is irremovable when it is positioned in the hinges 14', whatever the movements imposed on the plate 4 and the spring blades 13.
