Description

DESCRIPTION DESCRIPTION
Titre : Table extensible à roulettes Title: Extendable table with casters
La présente invention concerne une table extensible destinée à être utilisée dans une habitation. The present invention relates to an extendable table for use in a dwelling.
Une telle table extensible permet dans sa configuration repliée, d'occuper une surface relativement réduite pour accueillir un nombre de couverts restreints. Dans sa configuration étendue, utilisée par exemple lors d'une fête de famille, sa surface est augmentée et le nombre de couverts qu'elle peut recevoir est accru. Such an extendable table makes it possible, in its folded configuration, to occupy a relatively small area to accommodate a small number of place settings. In its extended configuration, used for example at a family celebration, its surface area is increased and the number of place settings that it can receive is increased.
Dans le document FR77045, est présentée une table -rallonge. Elle se compose de deux traverses latérales intérieures reliées à une paire de pieds d'extrémité et supportant un plateau, deux traverses latérales extérieures montées à coulissement le long des deux traverses latérales intérieures et qui sont reliées à une autre paire de pieds d'extrémité. Les traverses latérales intérieures sont reliées aux traverses latérales extérieures par deux glissières en queue d'aronde. En position d'extension, les deux traverses latérales extérieures peuvent recevoir un panneau d'allonge prolongeant le plateau. Bien que de construction simple, cette table manque de rigidité notamment sur les grandes longueurs de table. In document FR77045, an extension table is presented. It consists of two inner side rails connected to a pair of end legs and supporting a tray, two outer side rails slidably mounted along the two inner side rails and which are connected to another pair of end legs. The inner side rails are connected to the outer side rails by two dovetail guides. In the extended position, the two outer side rails can receive an extension panel extending the platform. Although of simple construction, this table lacks rigidity especially on long table lengths.
Partant de ce constat, le demandeur a cherché à concevoir une table qui présente une rigidité accrue, et une facilité d'usage améliorée, notamment sur une grande longueur. A cet effet, est proposée une table extensible comprenant un châssis fixe supportant un plateau de table, un châssis coulissant monté à coulissement sur ledit châssis fixe et des piètements destinés à prendre appui sur le sol. Selon l'invention, le châssis fixe est équipé d'un premier piètement disposé à proximité de l'une de ses extrémités, et le châssis coulissant est équipé d'un second piètement et d'un troisième piètement disposés respectivement à proximité de ses deux extrémités, le second piètement étant considéré comme étant celui le plus proche du premier piètement, le second piètement étant pourvu d'au moins une roulette de roulage sur le sol. Based on this observation, the applicant sought to design a table which has increased rigidity and improved ease of use, in particular over a great length. To this end, an extendable table is proposed comprising a fixed frame supporting a table top, a sliding frame slidably mounted on said fixed frame and legs intended to rest on the ground. According to the invention, the fixed frame is equipped with a first base arranged near one of its ends, and the sliding frame is equipped with a second base and a third base respectively arranged near its two. ends, the second base being considered to be the one closest to the first base, the second base being provided with at least one rolling wheel on the ground.
La rigidité de la table extensible de l'invention est augmentée par le second piètement d'appui au sol qui est disposé idéalement au centre de la table dans sa configuration étendue. Le châssis coulissant de la table peut être tiré et repoussé facilement dans la mesure où il repose sur ces deux piètements dont le second piètement roulant supporte pratiquement la moitié de la masse du châssis fixe et du plateau de table. The rigidity of the extendable table of the invention is increased by the second ground support leg which is ideally placed in the center of the table in its extended configuration. The sliding table frame can be pulled and pushed back easily as it rests on these two legs, the second rolling base of which supports almost half the mass of the fixed frame and the table top.
Selon une caractéristique additionnelle de l'invention, le châssis fixe comprend deux longerons latéraux fixes fixés parallèlement sous le plateau et le châssis coulissant comprend deux longerons latéraux coulissants respectivement montés à coulissement le long des deux longerons latéraux fixes, chaque longeron latéral fixe et son longeron latéral coulissant correspondant étant réunis par l'intermédiaire d'un moyen de guidage en translation. Le châssis coulissant peut se déplacer le long du châssis fixe. According to an additional characteristic of the invention, the fixed frame comprises two fixed side rails fixed in parallel under the platform and the sliding frame comprises two sliding side rails respectively mounted to slide along the two fixed side rails, each fixed side rail and its side member. corresponding sliding side being joined together by means of guide means in translation. The sliding frame can move along the fixed frame.
Avantageusement, le moyen de guidage en translation comprend une rainure creusant la face externe du longeron latéral coulissant, une pluralité de galets fixés sur le longeron latéral fixe tourné en vis-à-vis, ou inversement, et qui prennent place dans ladite rainure. Ce moyen de guidage en translation procure un déplacement fluide du châssis coulissant. Advantageously, the means for guiding in translation comprises a groove hollowing out the outer face of the sliding lateral spar, a plurality of rollers fixed to the fixed lateral spar turned opposite, or vice versa, and which take place in said groove. This translational guide means provides a fluid movement of the sliding frame.
Selon une caractéristique additionnelle de l'invention, ladite ou chaque roulette du second piètement du châssis coulissant est du type non pivotant, son axe de rotation étant perpendiculaire par rapport à la direction de déplacement du châssis coulissant. According to an additional characteristic of the invention, said or each wheel of the second base of the sliding frame is of the non-swivel type, its axis of rotation being perpendicular to the direction of movement of the sliding frame.
Ladite roulette accompagne sans s'y opposer le mouvement de coulissement du châssis coulissant. Said wheel accompanies without opposing it the sliding movement of the sliding frame.
Selon une caractéristique additionnelle de l'invention, le châssis coulissant incorpore au moins un élément d'allonge destiné à prolonger, dans le même plan, la surface du plateau. According to an additional characteristic of the invention, the sliding frame incorporates at least one extension element intended to extend, in the same plane, the surface of the plate.
La présence de ce ou de ces éléments d'allonge permet d'augmenter la surface utile de la table. The presence of this or these extension elements makes it possible to increase the useful surface of the table.
Avantageusement, ledit élément d'allonge est formé de deux volets de géométrie carrée ou rectangulaire en vue de dessus et qui sont reliés par l'intermédiaire d'une articulation réunissant deux de leurs bords longitudinaux. Advantageously, said extension element is formed of two flaps of square or rectangular geometry in top view and which are connected by means of a hinge joining two of their longitudinal edges.
Les deux volets peuvent ainsi prendre une position repliée de rangement sous le plateau de table et une position de déploiement pour étendre la surface utile de la table. Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels : The two flaps can thus take a folded storage position under the table top and a deployment position to extend the useful surface of the table. The characteristics of the invention mentioned above, as well as others, will emerge more clearly on reading the following description of an exemplary embodiment, said description being given in relation to the accompanying drawings, among which:

La table extensible 100 présentée sur la Fig. 1 est destinée à être utilisée de manière conventionnelle dans une habitation pour servir notamment, de table pour servir les repas. The extendable table 100 shown in FIG. 1 is intended to be used in a conventional manner in a home, in particular to serve as a table for serving meals.
La table extensible 100 se compose sur cette Fig. 1 d'un châssis Ch monté sur trois piètements PI, P2 et P3, destinés à prendre appui sur le sol, et sur lequel est monté un plateau Pp de table. The extendable table 100 is composed in this FIG. 1 of a frame Ch mounted on three legs PI, P2 and P3, intended to rest on the ground, and on which is mounted a table top Pp.
Sur la Fig. 2, le châssis Ch se compose d'un châssis fixe ChF et d'un châssis coulissant ChC monté à coulissement dans le châssis fixe ChF. Le châssis coulissant ChC est celui sur lequel on tire pour allonger la table 100. In Fig. 2, the Ch frame consists of a fixed ChF frame and a ChC sliding frame slidably mounted in the ChF fixed frame. The sliding frame ChC is the one on which one pulls to lengthen the table 100.
Sur la Fig. 3, le châssis fixe ChF comprend deux longerons latéraux fixes L1F fixés parallèlement sous le plateau Pp. Le châssis coulissant ChC comprend deux longerons latéraux coulissants L1C respectivement montés à coulissement le long des deux longerons latéraux fixes L1F. Les deux longerons latéraux coulissants L1C sont sur cette Fig. 3 disposés entre les deux longerons latéraux fixes L1F. In Fig. 3, the fixed frame ChF comprises two fixed side rails L1F fixed in parallel under the platform Pp. The sliding chassis ChC comprises two sliding side rails L1C respectively mounted to slide along the two fixed side rails L1F. The two sliding side members L1C are in this Fig. 3 arranged between the two fixed side rails L1F.
Le châssis fixe ChF est porté par le piètement Pl. The fixed ChF frame is carried by the Pl base.
Le châssis coulissant ChC est porté par le piètement P2 et par le piètement P3. Ces deux caractéristiques sont clairement visibles sur les Figs. 4 et 5. The ChC sliding frame is carried by the P2 base and by the P3 base. These two characteristics are clearly visible in Figs. 4 and 5.
Sur la Fig. 3, chaque longeron latéral fixe L1F et son longeron latéral coulissant L1C correspondant sont réunis par l'intermédiaire d'un moyen de guidage en translation. Celui-ci est préférentiellement constitué d'une rainure Rn creusant, par exemple, la face externe du longeron latéral coulissant L1C et d'une pluralité de galets Gl, tels que des roulements à billes fixés sur le longeron latéral fixe L1F tourné en vis-à-vis et qui prennent place dans ladite rainure. Ce moyen de guidage en translation procure un glissement fluide du châssis coulissant ChC. In Fig. 3, each fixed lateral spar L1F and its corresponding sliding lateral spar L1C are joined by means of a translational guide means. This preferably consists of a groove Rn hollowing out, for example, the external face of the sliding side spar L1C and of a plurality of rollers Gl, such as ball bearings fixed on the fixed side spar L1F turned in screw- vis-à-vis and which take place in said groove. This translational guide means provides fluid sliding of the sliding frame ChC.
Les galets ainsi qu'une rainure Rn correspondante sont également visibles sur les Figs. 4 et 5. Ainsi, en tirant par son extrémité accessible le châssis coulissant ChC, suivant la direction indiquée par la flèche F sur la Fig. 5, on peut étendre la longueur de la table 100. The rollers as well as a corresponding groove Rn are also visible in Figs. 4 and 5. Thus, by pulling the sliding frame ChC by its accessible end, in the direction indicated by the arrow F in FIG. 5, the length of the table 100 can be extended.
Le châssis coulissant ChC peut facilement être déplacé sur le sol car il est porté par ses deux piètements P2 et P3. Les deux piètement P2 et P3 sont globalement disposés aux deux extrémités du châssis coulissant ChC. The ChC sliding frame can easily be moved on the ground because it is carried by its two legs P2 and P3. The two legs P2 and P3 are generally arranged at the two ends of the sliding frame ChC.
Dans l'invention, le piètement P2 est équipé d'au moins une roulette de roulement sur le sol pour faciliter le déplacement du châssis coulissant ChC, à l'endroit où il supporte pratiquement la moitié de la masse du châssis fixe ChF et du plateau de table. La rigidité de la table est accrue et le déplacement de ce châssis coulissant ChC est aisé à mettre en œuvre. In the invention, the base P2 is equipped with at least one rolling wheel on the ground to facilitate the movement of the sliding frame ChC, to the place where it supports practically half of the mass of the fixed frame ChF and of the table top. of table. The rigidity of the table is increased and the displacement of this sliding frame ChC is easy to implement.
Sur les Figs. 1 et 2, chaque piètement Pl, P2 et P3, est formé d'un support terminé dans sa partie basse par l'intermédiaire de deux roulettes destinées à reposer sur le sol. Chaque support est formé de deux pieds réunis par un traverse. Sur ces Figs. 1 et 2, les roulettes sont du type pivotant pour pouvoir déplacer la table dans toutes les directions sur le sol. In Figs. 1 and 2, each base P1, P2 and P3, is formed of a support terminated in its lower part by means of two rollers intended to rest on the ground. Each support is formed by two feet joined by a cross member. In these Figs. 1 and 2, the casters are of the swivel type to be able to move the table in all directions on the floor.
Sur la Fig. 2, le châssis coulissant ChC incorpore au moins un élément d'allonge Ea destiné à prolonger dans le même plan, la surface du plateau Pp. Trois éléments d'allonge Ea équipent sur la Fig. 2 le châssis coulissant ChC. Chaque élément d'allonge Ea est formé de deux volets de géométrie carrée ou rectangulaire en vue de dessus qui sont reliés par l'intermédiaire d'une articulation réunissant deux de leurs bords longitudinaux. Les deux volets sont repliés l'un sur l'autre dans leur position de non utilisation visible sur cette Fig. 2 et le châssis coulissant ChC peut librement coulisser sous le plateau Pp de la table extensible 100. In Fig. 2, the sliding frame ChC incorporates at least one extension element Ea intended to extend, in the same plane, the surface of the plate Pp. Three extension elements Ea are fitted in FIG. 2 the ChC sliding frame. Each extension element Ea is formed of two flaps of square or rectangular geometry in top view which are connected by means of a hinge joining two of their longitudinal edges. The two flaps are folded over one another in their non-use position visible in this FIG. 2 and the sliding frame ChC can slide freely under the Pp table top of the extendable table 100.
Un arbre Ab traverse longitudinalement le châssis coulissant ChC. Un volet de chaque paire est monté libre à rotation autour de cet arbre Ab. On peut ainsi déplier les deux volets suivant un mouvement d'aile de papillon pour qu'ils puissent s'ouvrir et s'étendre horizontalement dans le prolongement du plateau Pp de la table 100. La table incorpore des butées qui sont disposées pour maintenir chaque paire de volets, notamment dans leur position d'ouverture horizontale. On fait coulisser chaque paire de volets sur l'arbre Ab pour qu'ils puissent prendre appui horizontalement sur lesdites butées. A shaft Ab crosses the sliding frame ChC longitudinally. One flap of each pair is mounted to rotate freely around this shaft Ab. We can thus unfold the two flaps following a butterfly wing movement so that they can open and extend horizontally in the extension of the plate Pp of the table 100. The table incorporates stops which are arranged to hold each pair of shutters, in particular in their horizontal open position. Each pair of flaps is slid on the shaft Ab so that they can bear horizontally on said stops.
Le châssis coulissant ChC est équipé de roulettes de guidage d'au moins un volet pour le guider pendant son mouvement d'ouverture et de fermeture. Le châssis coulissant ChC est également équipé de butées pour maintenir en position les deux volets, soit dans leur position repliée, soit dans leur position dépliée. The ChC sliding frame is equipped with guide rollers for at least one shutter to guide it during its opening and closing movement. The ChC sliding frame is also equipped with stops to hold the two shutters in position, either in their folded position or in their unfolded position.
Les éléments d'allonge Ea peuvent également coulisser le long de cet arbre Ab pour être jointifs deux à deux. Les éléments d'allonge Ea sont sur la Fig. 6 disposés dans leur position active, dans laquelle ils prolongent le plateau Pp de la table 100. The extension elements Ea can also slide along this shaft Ab to be contiguous in pairs. The extension elements Ea are in FIG. 6 arranged in their active position, in which they extend the plate Pp of the table 100.
La table extensible 100 de l'invention est aussi rigide dans sa configuration non étendue que dans sa configuration étendue. Le déplacement de son châssis coulissant est rendu aisé par la présence de roulettes sur son piètement P2. The extendable table 100 of the invention is as rigid in its non-extended configuration as it is in its extended configuration. The movement of its sliding frame is made easy by the presence of casters on its P2 base.
Dans la variante de réalisation présentée sur la Fig. 7, les piétements PI et P3 de la table extensible 100 sont constitués de pieds dépourvus de roulettes et prennent appui donc directement sur le sol. Ils peuvent cependant être équipés de patins de glissement. Le piètement P2 du châssis coulissant Chc est constitué d'un pied unique fixé dans sa partie basse, sur une traverse portant à ses deux extrémité deux roulettes. Les roulettes sont du type non pivotant. L'axe de rotation des deux roulettes est perpendiculaire par rapport à la direction de déplacement du châssis coulissant ChC pour faciliter encore la fluidité du mouvement du châssis coulissant ChC. In the variant embodiment presented in FIG. 7, the legs PI and P3 of the extendable table 100 consist of feet without casters and therefore rest directly on the ground. However, they can be fitted with sliding pads. The P2 base of the Chc sliding frame consists of a single foot fixed in its lower part, on a cross member carrying at its two ends two casters. The casters are of the non-swivel type. The axis of rotation of the two rollers is perpendicular to the direction of movement of the sliding frame ChC to further facilitate the fluidity of movement of the sliding frame ChC.
Dans une variante de réalisation, non représentée, le second piètement du châssis coulissant n'est équipé que d'une seule roulette. Elle est également du type non pivotant, c'est-à-dire que l'axe de rotation de la roulette est perpendiculaire par rapport à la direction de déplacement du châssis coulissant. In an alternative embodiment, not shown, the second base of the sliding frame is equipped with only one wheel. She is also of the type non-swiveling, that is to say that the axis of rotation of the caster is perpendicular to the direction of movement of the sliding frame.
Les roulettes sont équipées de bandage en caoutchouc pour réduire le bruit de roulage. The casters are fitted with rubber tires to reduce rolling noise.
