Une telle table peut avoir diverses applications et, en particulier, celle de supporter un outillage, tel qu'une scie circulaire utilisée dans le domaine du bâtiment.The present invention relates to a table of the type having at least one foot or foldable frame mounted on a frame. Such a table can have various applications and, in particular, that of supporting tools such as saws Circular used in the field of building.

Lors de la construction ou de la réfection d'un bâtiment, il est souvent nécessaire de transporter d'un chantier à l'autre ou d'un endroit à l'autre sur un même chantier des tables de travail, par exemple équipées d'outillages tels que des scies circulaire pour matériaux de construction tels que du carrelage ou des parpaings. Ces tables doivent pouvoir être mises en place rapidement sans nécessiter l'utilisation de clefs ou autres outils spécifiques.When building or repairing a building, it is often necessary to transport from one site to another or from one place to another on the same construction of work tables, for example equipped with tools such as saws circular for building materials such as tiling or blocks. These tables must be able to be put in place quickly without requiring the use of keys or other specific tools.

On connaít des tables dont les pieds de table sont repliables pour obtenir un encombrement moindre desdites tables lors de leur transport et pour faciliter leur mise en place sur les chantiers. Le document US-A-4 144 822 décrit une table dont les pieds sont repliables.Tables are known whose table legs are collapsible to obtain a less space of said tables during their transport and to facilitate their set up on construction sites. US-A-4,144,822 discloses a table whose legs are foldable.

Les tables à pieds repliables connues comportent généralement des pieds articulés individuellement ou par paire autour d'un axe de rotation, si bien que lesdits pieds peuvent prendre une position repliée sous ledit châssis de la table et une position dépliée où lesdits pieds supportent ledit châssis. Le blocage en position pliée ou dépliée se font grâce à un dispositif de blocage qui est généralement constitué d'un verrou bloquant le pied ou la paire de pieds dans l'une ou l'autre position. Ce verrou est déblocable en manoeuvrant un organe dudit dispositif de blocage. Known folding tables usually have feet articulated individually or in pairs around an axis of rotation, so that said feet can take a folded position under said table frame and a unfolded position where said feet support said frame. Blocking in the folded position or unfolded by means of a locking device which is generally constituted a lock blocking the foot or the pair of feet in one or the other position. This lock is unlockable by operating a member of said locking device.

Le problème rencontré par de telles tables est que le dispositif de blocage n'est pas nécessairement facilement accessible et il en résulte une mise en place parfois longue et pas toujours aisée.The problem encountered by such tables is that the blocking device is not necessarily easily accessible and the result is sometimes long and not always easy.

  • FIG. 4 is a view of a folding foot lock device shown in a folded position according to the invention, and
  • FIG. 5 shows a main view of a folding table shown in a transport position according to the invention.
  • La table représentée à la Fig. 1 est essentiellement constituée d'un châssis 10 pourvu d'un plateau 11, de deux piétements 20a prévus pour pouvoir prendre une position repliée sous le châssis 10 et une position dépliée où ils supportent ledit châssis 10.The table shown in FIG. 1 consists essentially of a chassis 10 provided with a plate 11, two legs 20a provided to be able to take a folded position under the frame 10 and an unfolded position where they support said chassis 10.

    Le plateau 11 est prolongé sur ses côtés latéraux par deux joues de rigidification 12a et 12b (seule la joue 12a est visible à la Fig. 1) respectivement destinés par exemple à la fixation d'une scie à disque (non représentée) par l'intermédiaire de deux joues de rigidification 12a et 12b (seule la joue 12a est visible à la Fig. 1) et d'un dispositif de fixation d'outillage 13.The plate 11 is extended on its lateral sides by two cheeks of stiffening 12a and 12b (only the cheek 12a is visible in Fig. 1) respectively for example for fixing a disc saw (not shown) by through two stiffening cheeks 12a and 12b (only the cheek 12a is visible in FIG. 1) and a tool attachment device 13.

    Une poignée 40 est fixée à chacun des côtés longitudinaux 12c et 12d du châssis 10. Un jeu de roulettes 50 est montée sous le plateau 11 à proximité de l'un des côtés longitudinaux 12c ou 12d.A handle 40 is attached to each of the longitudinal sides 12c and 12d of the chassis 10. A set of wheels 50 is mounted under the plate 11 near one longitudinal sides 12c or 12d.

    Le châssis 10 est supporté par deux piétements 20a et 20b formés de deux pieds 20 solidarisés l'un à l'autre au moyen d'une entretoise 21. The frame 10 is supported by two legs 20a and 20b formed of two feet 20 secured to one another by means of a spacer 21.

    Chaque pied 20 est monté dans un dispositif de blocage 30 constitué, dans l'exemple de réalisation représenté, d'un flasque 31 fixé à chacune des deux extrémités de deux traverses 14a ou 14b elles-mêmes fixées transversalement sous le plateau 11 entre les joues 12a et 12b.Each foot 20 is mounted in a locking device 30 constituted, in the embodiment shown, a flange 31 fixed to each of the two ends of two sleepers 14a or 14b themselves transversely fixed under the plateau 11 between the cheeks 12a and 12b.

    A la Fig. 2, la paroi du flasque 31 comporte une lumière 32 qui présente une forme de L d'axe principal A1 et d'axe secondaire A2 et dont les extrémités de la ont une forme de demi-cercle.In FIG. 2, the wall of the flange 31 has a light 32 which has a L shape of main axis A1 and secondary axis A2 and whose ends have a form of semicircle.

    Lorsque l'on manoeuvre le pied 20 pour le plier ou le déplier, un axe 23 qui est monté dans une paroi frontale 24 dudit pied 20 peut coulisser dans ladite lumière 32. L'axe 23 est positionné à faible distance de l'extrémité haute du pied 20, dans un plan médian à la paroi frontale 24. Ladite paroi frontale 24 du pied 20 est prévue pour entrer en contact avec le flasque 31, de préférence avec sa face interne comme cela est représenté à la Fig. 2.When maneuvering the foot 20 to fold or unfold it, an axis 23 which is mounted in a front wall 24 of said foot 20 can slide in said light 32. The axis 23 is positioned at a short distance from the upper end of the foot 20, in a median plane to the front wall 24. Said front wall 24 of the foot 20 is provided to contact the flange 31, preferably with its inner face as this is shown in FIG. 2.

    Le flasque 31 est également délimité à l'un de ses bords par une came 33 dont le profil présente une forme de portion de cercle. La came 33 est encadrée, d'une part, par une première gorge 34 de section semi-cylindrique dont le centre est situé dans le prolongement de l'axe principal A1 de la lumière 32 et, d'autre part, par une seconde gorge 35 de section semi-cylindrique dont le centre est situé dans le prolongement de l'axe secondaire A2 de la lumière 32.The flange 31 is also delimited at one of its edges by a cam 33 whose the profile has a shape of a portion of a circle. The cam 33 is framed, of a part, by a first groove 34 of semicylindrical section whose center is located in the extension of the main axis A1 of the light 32 and, on the other hand, by a second groove 35 of semi-cylindrical section whose center is located in the extension of the secondary axis A2 of the light 32.

    Un pion 25 est également monté dans un plan médian du pied 20 de manière à éloigné de l'axe 23 d'une distance égale au jeu près à la distance qui sépare l'axe de l'extrémité haute de la lumière, et l'axe de la première gorge 34 du même flasque.A pin 25 is also mounted in a median plane of the foot 20 so as to away from the axis 23 by a distance equal to the game close to the distance between the axis of the high end of the light, and the axis of the first groove 34 of the same flange.

    Lorsque le pion 25 se trouve logé dans l'une des deux gorges 34 et 35, le pied 20 ou le piétement 20a est immobilisé et bloqué dans une de ses deux positions : sa position repliée et sa position dépliée.When the pin 25 is housed in one of the two grooves 34 and 35, the foot 20 or the base 20a is immobilized and locked in one of its two positions: its folded position and unfolded position.

    Par ailleurs, lorsque l'on manoeuvre le pied 20 pour le plier ou le déplier, le pion 25 peut glisser sur le long du profil de ladite came 33.Moreover, when maneuvering the foot 20 to fold or unfold it, the pin 25 can slide along the profile of said cam 33.

    Une première butée 36 est rapportée sur la paroi du flasque 31 recevant la paroi frontale 24 du pied 20, en l'occurrence la paroi interne dudit flasque à la Fig. 2. Elle est disposée entre la seconde gorge 35 et la lumière 32 de telle sorte qu'elle puisse entrer en contact avec une paroi latérale 26 du pied 20, lorsque ledit pied 20 est dans une position dépliée comme cela est montré à la Fig. 2. A first stop 36 is attached to the wall of the flange 31 receiving the front wall 24 of the foot 20, in this case the inner wall of said flange in FIG. 2. It is disposed between the second groove 35 and the light 32 so that it can come into contact with a side wall 26 of the foot 20, when said foot 20 is in an unfolded position as shown in FIG. 2.

    Ladite butée 36 s'étend également jusqu'à la normale de l'axe 23, projetée sur la paroi latérale 26, c'est-à-dire non loin de l'extrémité haute du pied 20, pour servir de point de basculement audit pied 20 lors du pliage.Said abutment 36 also extends to the normal of the axis 23 projected on the side wall 26, that is to say not far from the upper end of the foot 20, to serve tipping point to said foot 20 during folding.

    Une seconde butée 37 est rapportée sur la paroi interne du flasque 31. Elle est disposée de telle sorte qu'elle puisse entrer en contact avec une paroi latérale 27 opposée à la paroi latérale 26 du pied 20, lorsque ledit pied est manoeuvré en position dépliée comme cela est montré à la Fig. 2.A second stop 37 is attached to the inner wall of the flange 31. It is arranged so that it can come into contact with a side wall 27 opposite to the side wall 26 of the foot 20, when said foot is maneuvered in position unfolded as shown in FIG. 2.

    Ladite butée 37 est positionnée au voisinage de la première gorge 34.Said stop 37 is positioned in the vicinity of the first groove 34.

    Un moyen de rappel 28 qui est, par exemple, un ressort de traction comme cela est représenté à la Fig. 2, est installé de manière à ce que chaque pion 25 exerce une force de rappel sur le pied 20 ou le piétement 20a de manière à maintenir le pion 25 logé soit à l'intérieur de la gorge 34 soit à l'intérieur de la gorge 25, ou encore le long du profil de la came 33.A return means 28 which is, for example, a tension spring as this is shown in FIG. 2, is installed so that each peg 25 exerts a restoring force on the foot 20 or the base 20a so as to hold the pawn 25 located either inside the groove 34 or inside the groove 25, or the along the profile of the cam 33.

    Le moyen de rappel est par exemple monté entre une traverse 14a ou 14b et l'entretoise 21 d'un piétement 20a ou 20b. Il est de plus positionné de sorte que l'axe reliant ses deux points d'attache passe, soit d'un côté de l'axe 23 lorsque le pied 20 est en position pliée, comme cela est visible à la Fig. 4, soit de l'autre côté de l'axe 23 lorsque le pied 20 est en position dépliée comme cela est visible à la Fig. 2.The return means is for example mounted between a cross member 14a or 14b and the spacer 21 of a base 20a or 20b. It is further positioned so that the axis connecting its two attachment points passes either on one side of the axis 23 when the foot 20 is in the folded position, as can be seen in FIG. 4, on the other side of the axis 23 when the foot 20 is in the unfolded position as can be seen in FIG. 2.

    A la Fig. 2, la table de l'invention est représentée en position de travail, c'est-à-dire avec ses pieds 20 dépliés.In FIG. 2, the table of the invention is shown in working position, that is to say with his feet 20 unfolded.

    Lorsque l'utilisateur souhaite replier les pieds 20 sous le plateau 11 de la table de l'invention, il plie successivement chacune des piétements 20a et 20b sous le plateau 11. Il exerce alors une traction sur le piétement 20a dans la direction indiquée par la flèche B de la Fig. 2. Pour se faire, il peut par exemple exercer cette traction en tirant sur l'un des pieds 20 du piétement 20a, ou exercer une traction sur l'entretoise 21 reliant les pieds 20 du piétement 20a.When the user wishes to fold the feet 20 under the plate 11 of the table of the invention, it successively folds each of the legs 20a and 20b under the plate 11. It then exerts traction on the base 20a in the direction indicated by arrow B in FIG. 2. To do this, it can for example exert this traction in pulling on one of the legs 20 of the base 20a, or exert a traction on the spacer 21 connecting the feet 20 of the base 20a.

    Le pion 25 de chacun des pieds 20 quitte ainsi la première gorge 34 d'un flasque 31, ce qui autorise la rotation au piétement 20a autour de chaque axe 23. Ensuite, l'utilisateur entraíne en rotation le piétement 20a de manière à ce que chaque pion 25 puisse glisser le long du profil de la came 33 d'un flasque 31 comme l'indique la flèche C à la Fig. 3.The pin 25 of each of the legs 20 thus leaves the first groove 34 of a flange 31, which allows rotation to the base 20a around each axis 23. Then, the user rotates the base 20a so that each pin 25 can slide along the profile of the cam 33 of a flange 31 as indicates the arrow C in FIG. 3.

    Le moyen de rappel 28 maintient en contact le pion 25 de chacun des pieds 20 contre le profil de la came 33 d'un flasque 31. La paroi latérale 26 de chacun des pieds 20 entre alors en contact avec la première butée 36 d'un flasque 31, ce qui permet à l'axe 23 de chacun des pieds 20 de coulisser le long de l'axe principal A1 de la lumière 32 d'un flasque 31.The return means 28 keeps in contact the pin 25 of each of the legs 20 against the profile of the cam 33 of a flange 31. The side wall 26 of each of the feet 20 then comes into contact with the first stop 36 of a flange 31, which allows the shaft 23 of each of the legs 20 to slide along the main axis A1 of the light 32 of a flange 31.

    Le pion 25 de chacun des pieds 20 poursuit son déplacement sur le profil de la came 33 d'un flasque 31 de la sorte que l'axe reliant les deux points d'attache du moyen de rappel 28 croise chacun des axes 23 et passe de l'autre côté desdits axes, ce qui réduit l'effort de manoeuvre nécessaire au pliage du piétement 20a.The pin 25 of each of the legs 20 continues its movement on the profile of the cam 33 of a flange 31 so that the axis connecting the two attachment points of the return means 28 crosses each of the axes 23 and passes on the other side of said axes, this which reduces the maneuvering force required to fold the base 20a.

    Le pion 25 de chacun des pieds 20 termine son trajet sur le profil de la came 33 pour venir se loger dans la seconde gorge 35 d'un flasque 31, comme le montre la Fig. 4. Le moyen de rappel 28 entraíne alors l'axe 23 de chacun des pieds 20 dans le fond de la lumière 32 d'un flasque 31 suivant son axe secondaire A2, ce qui bloque chacun des pions 25 dans la seconde gorge 35 d'un flasque 31 et bloque par conséquent le piétement 20a sous le plateau 11 et parallèlement à lui.The pin 25 of each of the legs 20 ends its path on the profile of the cam 33 to be housed in the second groove 35 of a flange 31, as shown in FIG. Fig. 4. The return means 28 then drives the axis 23 of each of the feet 20 in the bottom of the light 32 of a flange 31 along its secondary axis A2, which blocks each of the pins 25 in the second groove 35 of a flange 31 and blocks by therefore the base 20a under the plate 11 and parallel to it.

    L'utilisateur procède de la même manière pour plier le piétement 20b sous le plateau 11. A la Fig. 5, les deux piétements 20a et 20b sont pliées parallèlement sous le plateau 11 et sont en contact l'une de l'autre par leurs parois latérales.The user proceeds in the same way to fold the base 20b under the tray 11. In FIG. 5, the two legs 20a and 20b are folded parallel under the plate 11 and are in contact with each other by their side walls.

    La table à pieds repliables peut être soulevée par ses poignées 40. Elle peut également être déplacée par une poignée 40, la table reposant au sol sur ses roulettes 50.The folding table can be lifted by its handles 40. It can also be moved by a handle 40, the table resting on the ground on its casters 50.

    Lorsque l'utilisateur souhaite déplier les piétements 20a et 20b, il commence par déplier le piétement 20b, puis le piétement 20a. Le dépliage du piétement 20b étant identique au dépliage du piétement 20a, seul celui-ci est décrit ci-après.When the user wishes to unfold the legs 20a and 20b, he begins by unfolding the base 20b, then the base 20a. The unfolding of the base 20b being identical to the unfolding of the base 20a, only this one is described below.

    L'utilisateur exerce une traction sur le piétement 20a dans la direction indiquée par la flèche D de la Fig. 4. Il peut par exemple exercer cette traction en tirant sur l'un des pieds 20 du piétement 20a, ou exercer une traction sur l'entretoise 21 reliant le piétement 20a. Le pion 25 de chacun des pieds 20 quitte alors la seconde gorge 35 d'un flasque 31, alors que l'axe 23 de chacun des pieds 20 coulisse le long de l'axe secondaire A2 de la lumière 32 d'un flasque 31. Puis, l'utilisateur entraíne en rotation le piétement 20a autour des axes 23, comme l'indique la flèche E de la Fig. 3.The user exerts traction on the base 20a in the direction indicated by the arrow D of FIG. 4. It can for example exert this traction in pulling on one of the legs 20 of the base 20a, or exert a traction on the spacer 21 connecting the base 20a. The pin 25 of each of the legs 20 then leaves the second 35 of a flange 31, while the axis 23 of each of the feet 20 slides along of the secondary axis A2 of the light 32 of a flange 31. Then, the user leads in rotation the base 20a about the axes 23, as indicated by the arrow E of FIG. 3.

    Le pion 25 de chacun des pieds 20 glisse ensuite le long du profil de la came 33 d'un flasque 31. Pendant ce temps, le moyen de rappel 28 maintient toujours en contact le pion 25 de chacun des pieds 20 contre la came 33 d'un flasque 31. The pin 25 of each of the legs 20 then slides along the profile of the cam 33 of a flange 31. Meanwhile, the biasing means 28 still maintains contact the pin 25 of each of the feet 20 against the cam 33 of a flange 31.

    L'axe reliant les deux points d'attache du moyen de rappel 28 croise une nouvelle fois chacun des axes 23 et passe de l'autre côté desdits axes, ce qui réduit l'effort de manoeuvre nécessaire au dépliage du piétement 20a.The axis connecting the two attachment points of the return means 28 intersects a once again each axis 23 and passes on the other side of said axes, which reduces the maneuvering force necessary to unfold the base 20a.

    Le pion 25 de chacun des pieds 20 poursuit son trajet sur la came 33 pour venir se loger dans la première gorge 34 d'un flasque 31 comme le montre la Fig. 2. Le moyen de rappel 28 entraíne également l'axe 23 de chacun des pieds 20 dans le fond de la lumière 32 suivant son axe principal A1, ce qui bloque chacun des pions 25 dans la première gorge 34 d'un flasque 31 et verrouille par conséquent le piétement 20a en position dépliée, c'est-à-dire dans la position de travail de la table de l'invention.The pin 25 of each of the legs 20 continues its path on the cam 33 to to be housed in the first groove 34 of a flange 31 as shown in FIG. 2. The return means 28 also causes the axis 23 of each of the legs 20 in the bottom of light 32 along its main axis A1, which blocks each piece 25 in the first groove 34 of a flange 31 and therefore locks the base 20a in unfolded position, that is to say in the working position of the table of the invention.

    Par ailleurs, la paroi latérale 27 de chacun des pieds 20 entre en contact à ce moment là avec la seconde butée 37 d'un flasque 31, ce qui limite encore le déplacement angulaire de chacun des pieds 20.Moreover, the side wall 27 of each of the feet 20 comes into contact with it. moment with the second stop 37 of a flange 31, which further limits the angular displacement of each of the feet 20.

    Chaque pied 20 est ainsi encastré respectivement entre la première butée 36 et la seconde butée 37 d'un flasque 31 soudé au châssis de la table par ses deux parois latérales 26 et 27.Each foot 20 is thus embedded respectively between the first stop 36 and the second stop 37 of a flange 31 welded to the frame of the table by its two walls lateral 26 and 27.

    Comme cela a déjà été dit ci avant, une troisième paroi d'un pied, la paroi frontale 24 est en contact avec un flasque 31. Ainsi, trois parois 26, 27 et 24 de chacun des pieds 20 est en contact avec un flasque 31 quand ledit pied est dans sa position dépliée. Il en résulte une grande rigidité de la liaison du châssis 10 de la table et de ses pieds 20.As already mentioned above, a third wall of a foot, the wall front 24 is in contact with a flange 31. Thus, three walls 26, 27 and 24 of each of the feet 20 is in contact with a flange 31 when said foot is in its unfolded position. This results in a high rigidity of the connection of the chassis 10 of the table and his feet 20.

    On notera que les opérations de pliage et le dépliage des pieds de la table de l'invention sont simplifiées ne nécessitent pas l'emploi d'outils de la part de son utilisateur. Ces opérations peuvent donc être mises en oeuvre très rapidement.Note that folding operations and unfolding the feet of the table of the invention are simplified do not require the use of tools from his user. These operations can therefore be implemented very quickly.
