Definitions
- the present invention relates to a table of the type having at least one leg or folding base mounted on a chassis.
- a table can have various applications and, in particular, that of supporting a tool, such as a saw circular used in the building industry.
- Known folding leg tables generally have legs articulated individually or in pairs around an axis of rotation, so that said legs can assume a folded position under said table frame and a unfolded position where said feet support said frame. Locking in the folded position or unfolded are done thanks to a blocking device which is generally constituted a lock blocking the foot or the pair of feet in either position. This lock is unlockable by operating a member of said locking device.
- the object of the invention is therefore to propose a table of the type which comprises at minus a folding foot or base whose maneuver for blocking and unlocking is easier.
- the table whose legs are foldable is remarkable in that it includes a locking device provided to allow the sliding of each foot or base in order to authorize its blocking and unblocking in each from its folded and unfolded positions.
- said leg or base to go from its folded position to its unfolded position and vice versa, is articulated around an axis;
- said blocking device comprises a pin intended for enter each of two grooves in order to block said foot or base in each of said folded and unfolded positions;
- the locking device comprises also a light provided to allow the axis to slide in the direction of both throats
- the pawn is designed to slide on the profile of a cam arranged between the first and second grooves when said foot or base passes from its folded position to its position unfolded and vice versa.
- the invention includes a return means acting on said foot or base so as to maintain the pin in the grooves or against the cam.
- said device for blocking comprises a first and second stops provided for respectively serving abutment at the side walls of a foot or base when said foot or base is in its unfolded position.
- the first stop is designed to limit the angular displacement of a foot or a base in its folded position.
- the first stop extends to the normal of the axis projected on the side wall, to serve as a point tilting of a foot or base during its folding.
- the table is provided at least one handle or a set of casters.
- the table shown in FIG. 1 essentially consists of a chassis 10 provided with a plate 11, two legs 20a provided to take a folded position under the frame 10 and an unfolded position where they support said chassis 10.
- 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 intended 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 fixing device 13.
- a handle 40 is fixed to each of the longitudinal sides 12c and 12d of the chassis 10.
- a set of rollers 50 is mounted under the plate 11 near one longitudinal sides 12c or 12d.
- the chassis 10 is supported by two legs 20a and 20b formed by two feet 20 secured to each other by means of a spacer 21.
- Each leg 20 is mounted in a blocking device 30 constituted, in the embodiment shown, of a flange 31 fixed to each of the two ends of two crosspieces 14a or 14b themselves fixed transversely under the plate 11 between the cheeks 12a and 12b.
- the wall of the flange 31 has a lumen 32 which has a L-shape of main axis A1 and secondary axis A2 and the ends of which have a semicircle shape.
- an axis 23 which is mounted in a front wall 24 of said foot 20 can slide in said lumen 32.
- the axis 23 is positioned a short distance from the high 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 come into contact with the flange 31, preferably with its internal face as this is shown in Fig. 2.
- the flange 31 is also delimited at one of its edges by a cam 33 whose the profile has the shape of a portion of a circle.
- Cam 33 is framed with a part, by a first groove 34 of semi-cylindrical 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.
- a pin 25 is also mounted in a median plane of the foot 20 so as to distant from the axis 23 by a distance equal to the clearance close to the distance which separates the axis from the upper end of the lumen, and the axis of the first groove 34 of the same flange.
- the foot 20 or the base 20a is immobilized and blocked in one of its two positions: its folded position and its unfolded position.
- the pin 25 can slide along the profile of said cam 33.
- a first stop 36 is attached to the wall of the flange 31 receiving the front wall 24 of foot 20, in this case the internal wall of said flange in FIG. 2. It is arranged 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.
- Said stop 36 also extends to the normal of axis 23, projected onto the side wall 26, that is to say not far from the high end of the foot 20, to serve tipping point at said foot 20 during folding.
- a second stop 37 is attached to the internal wall of the flange 31. It is arranged so that it can come into contact with a side wall 27 opposite the side wall 26 of the foot 20, when said foot is maneuvered into position unfolded as shown in Fig. 2.
- Said stop 37 is positioned in the vicinity of the first groove 34.
- a return means 28 which is, for example, a tension spring as this is shown in Fig. 2, is installed so that each pin 25 exerts a restoring force on the foot 20 or the base 20a so as to maintain the pin 25 housed either inside throat 34 or inside throat 25, or else the along the profile of the cam 33.
- the return means is for example mounted between a crosspiece 14a or 14b and the spacer 21 of a base 20a or 20b. It is also positioned so that the axis connecting its two attachment points passes, that is to say on one side of the axis 23 when the foot 20 is in the folded position, as can be seen in FIG. 4, either on the other side of the axis 23 when the foot 20 is in the unfolded position as can be seen in FIG. 2.
- Fig. 2 the table of the invention is shown in the working position, that is to say with its 20 feet unfolded.
- the user When the user wishes to fold the feet 20 under the table top 11 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, he can for example exert this traction by pulling on one of the feet 20 of the base 20a, or exerting traction on the spacer 21 connecting the feet 20 of the base 20a.
- each of the feet 20 thus leaves the first groove 34 of a flange 31, which allows rotation at 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 cam 33 of a flange 31 as indicated by arrow C in FIG. 3.
- the return means 28 keeps the pin 25 of each of the feet 20 in contact 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 axis 23 of each of the feet 20 to slide along the main axis A1 of the light 32 of a flange 31.
- 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 effort necessary for folding the base 20a.
- 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 the 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.
- the folding legs 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 castors 50.
- the user exerts traction on the base 20a in the direction indicated by arrow D in Fig. 4. He can for example exert this traction in pulling on one of the feet 20 of the base 20a, or exerting traction on the spacer 21 connecting the base 20a.
- the pawn 25 on each of the feet 20 then leaves the second groove 35 of a flange 31, while the axis 23 of each of the legs 20 slides along of the secondary axis A2 of the light 32 of a flange 31. Then, the user trains rotation of the base 20a around the axes 23, as indicated by the arrow E of Fig. 3.
- the axis connecting the two attachment points of the return means 28 crosses a again each of the axes 23 and passes on the other side of said axes, which reduces the maneuvering effort required to unfold the base 20a.
- the pin 25 of each of the legs 20 continues its path on the cam 33 to come to lodge in the first groove 34 of a flange 31 as shown in FIG. 2.
- the return means 28 also drives the axis 23 of each of the feet 20 in the background of light 32 along its main axis A1, which blocks each of the pawns 25 in the first groove 34 of a flange 31 and therefore locks the base 20a in the unfolded position, i.e. in the working position of the table of the invention.
- each of the legs 20 comes into contact with this moment there with the second stop 37 of a flange 31, which further limits the angular displacement of each of the feet 20.
- Each leg 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 side 26 and 27.
- a third wall of one foot the wall front 24 is in contact with a flange 31.
- 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 great rigidity in the connection of the chassis 10 of the table and legs 20.

Description
La présente invention concerne une table du type ayant au moins un pied ou piétement repliable monté sur un châssis. 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 leg or folding base mounted on a chassis. Such a table can have various applications and, in particular, that of supporting a tool, such as a saw circular used in the building industry.
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 constructing or renovating 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 tiles or concrete blocks. These tables must be able to be set up quickly without requiring the use of keys or other specific tools.
On connaÃt 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.We know tables whose table legs are foldable to get a less bulk of said tables during transport and to facilitate their set up on construction sites.
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 leg tables generally have legs articulated individually or in pairs around an axis of rotation, so that said legs can assume a folded position under said table frame and a unfolded position where said feet support said frame. Locking in the folded position or unfolded are done thanks to a blocking device which is generally constituted a lock blocking the foot or the pair of feet in either 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 with such tables is that the blocking device is not necessarily easily accessible and this results in placement sometimes long and not always easy.
Le but de l'invention est donc de proposer une table du type qui comporte au moins un pied ou piétement repliable dont la manoeuvre pour le blocage et le déblocage est plus facile.The object of the invention is therefore to propose a table of the type which comprises at minus a folding foot or base whose maneuver for blocking and unlocking is easier.
A cet effet, la table dont ses pieds sont repliables est remarquable en ce qu'elle comporte un dispositif de blocage prévu pour permettre le coulissement de chaque pied ou piétement afin d'autoriser son blocage et son déblocage dans chacune de ses positions repliée et dépliée.To this end, the table whose legs are foldable is remarkable in that that it includes a locking device provided to allow the sliding of each foot or base in order to authorize its blocking and unblocking in each from its folded and unfolded positions.
Ainsi, le déblocage et le pliage des pieds est réalisé aisément.Thus, the release and folding of the feet is easily carried out.
Selon une autre caractéristique de la table de l'invention, ledit pied ou piétement, pour passer de sa position repliée à sa position dépliée et vice versa, est articulé autour d'un axe; ledit dispositif de blocage comporte un pion destiné à pénétrer dans chacune de deux gorges afin de bloquer ledit pied ou piétement dans chacune desdites positions repliée et dépliée; le dispositif de blocage comporte également une lumière prévue pour permettre le coulissement de l'axe en direction de l'une et l'autre gorgeAccording to another characteristic of the table of the invention, said leg or base, to go from its folded position to its unfolded position and vice versa, is articulated around an axis; said blocking device comprises a pin intended for enter each of two grooves in order to block said foot or base in each of said folded and unfolded positions; the locking device comprises also a light provided to allow the axis to slide in the direction of both throats
Selon une autre caractéristique de la table de l'invention, que le pion est prévu pour glisser sur le profil d'une came disposée entre les première et seconde gorges lorsque ledit pied ou piétement passe de sa position repliée à sa position dépliée et vice et versa..According to another characteristic of the table of the invention, that the pawn is designed to slide on the profile of a cam arranged between the first and second grooves when said foot or base passes from its folded position to its position unfolded and vice versa.
Selon une autre caractéristique de la table l'invention, qu'elle comprend un moyen de rappel agissant sur ledit pied ou piétement de manière à maintenir le pion dans les gorges ou contre la came.According to another characteristic of the table, the invention includes a return means acting on said foot or base so as to maintain the pin in the grooves or against the cam.
Selon une autre caractéristique de la table de l'invention, ledit dispositif de blocage comporte une première et seconde butées prévues pour respectivement servir de butée à des parois latérales d'un pied ou piétement lorsque ledit pied ou piétement est dans sa position dépliée.According to another characteristic of the table of the invention, said device for blocking comprises a first and second stops provided for respectively serving abutment at the side walls of a foot or base when said foot or base is in its unfolded position.
Selon une autre caractéristique de la table de l'invention, la première butée est prévue pour limiter le déplacement angulaire d'un pied ou d'un piétement dans sa position repliée. According to another characteristic of the table of the invention, the first stop is designed to limit the angular displacement of a foot or a base in its folded position.
Selon une autre caractéristique de la table de l'invention, la première butée s'étend jusqu'à la normale de l'axe projetée sur la paroi latérale, pour servir de point de basculement d'un pied ou piétement lors de son pliage.According to another characteristic of the table of the invention, the first stop extends to the normal of the axis projected on the side wall, to serve as a point tilting of a foot or base during its folding.
Selon une autre caractéristique de la table de l'invention, la table est munie d'au moins une poignée ou d'un jeu de roulettes.According to another characteristic of the table of the invention, the table is provided at least one handle or a set of casters.
Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres,
apparaÃtront 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:
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 essentially consists of a
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
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
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
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
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
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 the
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
Un pion 25 est également monté dans un plan médian du pied 20 de manière Ã
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
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
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.Furthermore, when the
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
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
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
Ladite butée 37 est positionnée au voisinage de la première gorge 34.Said
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
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
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 the working position, that is to say with its 20 feet 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
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 entraÃne 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
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 the
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
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 entraÃne 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
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
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 legs table can be lifted by its
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
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 entraÃne 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
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
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 crosses a

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 entraÃne 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
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.Furthermore, the
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
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 one foot, the
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 the folding operations and the unfolding of the legs of the table the invention are simplified do not require the use of tools on the part of its user. These operations can therefore be implemented very quickly.
