Description

La présente invention concerne les rayonnages à étagères, et notamment les rayonnages en bois dans lesquels les étagères reposent sur des montants verticaux.The present invention relates to shelving units with shelves, and in particular wooden shelving units in which the shelves rest on vertical uprights.

Ce genre de meubles comprend habituellement des montants verticaux reliés par des traverses et formant des cadres rigides entre lesquels les étagères sont posées. Les cadres sont reliés par des traverses obliques assurant la rigidité latérale de l'ensemble.This type of furniture usually includes vertical uprights connected by crosspieces and forming rigid frames between which the shelves are placed. The frames are connected by oblique crosspieces ensuring the lateral rigidity of the assembly.

Selon une réalisation courante, les montants comportent des entailles dans lesquelles sont insérées des pattes métalliques formant crochets pour coopérer avec des cornières métalliques transversales rapportées sous les étagères. Ce type de meubles peut être réalisé en bois, mais nécessite l'utilisation de pièces métalliques telles que les cornières, produisant un effet peu esthétique. Les étagères sont relativement peu maintenues, et peuvent être soumises à des mouvements de translation dans leur sens transversal ou de profondeur. En outre, la rigidité de l'ensemble n'est assurée que par les traverses obliques reliant les montants, les étagères ne participant pas à cette rigidité.According to a current embodiment, the uprights include notches in which are inserted metal tabs forming hooks to cooperate with transverse metal angles reported under the shelves. This type of furniture can be made of wood, but requires the use of metal parts such as angles, producing an unattractive effect. The shelves are relatively poorly maintained, and can be subjected to translational movements in their transverse or deep direction. In addition, the rigidity of the assembly is only ensured by the oblique crosspieces connecting the uprights, the shelves not participating in this rigidity.

Le brevet FR-A-2 394 272 décrit un rayonnage à étagères dans lequel les faces longitudinales en regard des montants comprennent une rainure verticale et des trous dans lesquels pénètrent des saillies formées par les extrémités d'un profil transversal métallique en U rapporté en bout des étagères. Un organe de sécurité, constitué d'une cale en forme de L, est posé entre une face longitudinale de l'étagère et la face en regard du montant, en reposant par sa branche horizontale sur la saillie. Dans ce dispositif, les saillies pénétrant dans les trous assurent le maintien vertical et longitudinal des étagères, l'organe de sécurité interdisant la translation latérale des étagères et le retrait des saillies hors des trous, retrait rendu possible par le jeu latéral indispensable à la mise en place. Cet assemblage n'assure pas une solidarisation efficace de l'ensemble car il n'interdit pas la rotation de l'étagère autour de l'axe formé par les saillies, et aucun blocage par coincement n'est assuré par l'organe de sécurité. Les rainures des montants n'ont pas de fonction participant à la tenue des étagères.Patent FR-A-2 394 272 describes a shelving unit in shelves in which the longitudinal faces opposite the uprights comprise a vertical groove and holes in which penetrate projections formed by the ends of a transverse metal U-shaped profile attached at the end shelves. A safety member, consisting of an L-shaped wedge, is placed between a longitudinal face of the shelf and the opposite face of the upright, resting by its horizontal branch on the projection. In this device, the projections entering the holes ensure the vertical and longitudinal retention of the shelves, the safety member preventing lateral translation of the shelves and the withdrawal of the projections outside the holes, withdrawal made possible by the lateral play essential for placing in place. This assembly does not ensure effective joining of the assembly because it does not prohibit the rotation of the shelf around the axis formed by the projections, and no jamming is ensured by the safety member. . The grooves of the uprights have no function participating in the holding of the shelves.

Le brevet US-A-3 056 508 décrit un rayonnage à étagères dans lequel les étagères sont munies en bout d'une barre transversale dont les extrémités forment saillies pour reposer dans des supports métalliques en U rapportés sur les faces en regard des montants. Un tel assemblage n'assure pas une solidarisation efficace, n'interdisant ni la rotation autour de l'axe formé par les saillies, ni le soulèvement vertical des étagères.US-A-3,056,508 describes a shelving unit in which the shelves are provided at the end of a transverse bar whose ends form projections to rest in metal U-shaped supports attached to the opposite faces of the uprights. Such an assembly does not ensure effective joining, neither prohibiting rotation about the axis formed by the projections, nor the vertical lifting of the shelves.

Le brevet FR-A-2142654 décrit un meuble obtenu par assemblage de panneaux dont une rainure en queue d'aronde coulisse sur un montant de profil complémentaire.Patent FR-A-2142654 describes a piece of furniture obtained by assembling panels of which a dovetail groove slides on an amount of complementary profile.

La présente invention a notamment pour objet de proposer un nouveau type de rayonnages à étagères pouvant être réalisé presque entièrement en bois, supprimant en particulier toutes pièces métalliques volumineuses telles que les cornières ou barres transversales en bout d'étagère.The object of the present invention is in particular to propose a new type of shelving which can be made almost entirely of wood, eliminating in particular any bulky metal parts such as the angles or transverse bars at the end of the shelf.

Un autre objet de l'invention est de réaliser un ensemble plus rigide par le fait que les étagères participent au maintien latéral de l'ensemble, tout en étant cependant démontables.Another object of the invention is to produce a more rigid assembly by the fact that the shelves participate in the lateral maintenance of the assembly, while however being removable.

Selon un autre objet de l'invention, les étagères sont bloquées dans toutes les directions de déplacement, et notamment dans leur sens trans- versai ou de profondeur, ainsi qu'en rotation d'axe transversal.According to another object of the invention, the shelves are locked in all directions of movement, and in particular in their transverse or depth direction, as well as in rotation of the transverse axis.

Selon un autre objet, l'invention propose une disposition selon laquelle l'assemblage des montants et des étagères est réalisable malgré les éventuelles déformations de ces éléments, notamment par le fait que le bois travaille, le jeu éventuel entre les parties de l'ensemble pouvant être automatiquement rattrapé.According to another object, the invention proposes a provision according to which the assembly of the uprights and the shelves is achievable despite the possible deformations of these elements, in particular by the fact that the wood works, the possible play between the parts of the assembly can be automatically caught.

Selon un autre objet, le même moyen d'assemblage peut être utilisé pour rapporter sur les montants d'autres éléments tels que des tablettes, plumiers, ou glissières pour tiroirs, par le fait que le blocage en rotation est suffisant.According to another object, the same assembly means can be used to attach to the uprights other elements such as shelves, pen trays or slides for drawers, by the fact that the rotation lock is sufficient.

Pour atteindre ces objets ainsi que d'autres, la présente invention prévoit d'utiliser des montants présentant deux faces longitudinales, c'est-à-dire parallèles à l'axe longitudinal des étagères, et deux faces transversales, c'est-à-dire parallèles à l'axe transversal des étagères ; la solidarisation des étagères et des montants est assurée par les moyens suivants : une rainure verticale médiane sur au moins l'une des faces longitudinales de chaque montant ; des prolongements longitudinaux. à chaque extrémité des étagères. destinés à s'engager entre les montants, et dont un côté comporte une nervure verticale conformée pour s'engager dans une rainure verticale de montant, et dont le côté opposé est oblique et comporte une rainure opposable à une rainure verticale d'un montant pour définir un logement destiné à recevoir une pièce de blocage en forme de coin ; des pièces de blocage en forme de coin conformées pour s'insérer entre la rainure verticale d'un montant et la rainure opposée du côté oblique d'un prolongement longitudinal d'étagère, et assurer le blocage latéral, longitudinal vertical et en rotation de l'étagère par rapport aux montants.To achieve these and other objects, the present invention provides for the use of uprights having two longitudinal faces, that is to say parallel to the longitudinal axis of the shelves, and two transverse faces, that is to say - say parallel to the transverse axis of the shelves; the shelves and uprights are joined together by the following means: a vertical vertical groove on at least one of the longitudinal faces of each upright; longitudinal extensions. at each end of the shelves. intended to engage between the uprights, and one side of which has a vertical rib shaped to engage in a vertical upright groove, and the opposite side of which is oblique and has a groove opposable to a vertical groove of an upright for defining a housing intended to receive a wedge-shaped blocking piece; wedge-shaped locking pieces shaped to fit between the vertical groove of an upright and the opposite groove on the oblique side of a longitudinal shelf extension, and ensure lateral, longitudinal vertical and rotating locking of the 'shelf in relation to the uprights.

Selon une disposition particulière de l'invention, les rainures verticales des montants ont un profil en V. Ce profil est particulièrement adapté à la réalisation de ces rayonnages, car il allie les qualités esthétiques des montants ainsi réalisés aux nécessités fonctionnelles des rainures. En outre, il assure un contact étroit, lors du coincement des pièces de blocage, entre les différentes faces des étagères et de leurs prolongements avec les faces longitudinales et transversales des montants.According to a particular arrangement of the invention, the vertical grooves of the uprights have a V-shaped profile. This profile is particularly suitable for the production of these shelving, because it combines the aesthetic qualities of the uprights thus produced with the functional needs of the grooves. In addition, it ensures close contact, during the jamming of the locking pieces, between the different faces of the shelves and their extensions with the longitudinal and transverse faces of the uprights.

Selon une autre caractéristique de l'invention, la longueur des prolongements est inférieure à la moitié de l'épaisseur des montants dans le sens longitudinal des étagères ; les pièces de blocage en coin ont une épaisseur sensiblement égale à la longueur des prolongements. De la sorte, deux étagères successives peuvent être assemblées bout à bout et solidarisées aux mêmes montants, une même rainure du montant pouvant admettre deux pièces de blocage en coin et deux prolongements d'étagères.According to another characteristic of the invention, the length of the extensions is less than half the thickness of the uprights in the longitudinal direction of the shelves; the corner blocking pieces have a thickness substantially equal to the length of the extensions. In this way, two successive shelves can be assembled end to end and secured to the same uprights, the same groove of the upright can admit two corner blocking pieces and two shelf extensions.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description suivante de modes de réalisation particuliers, faite en relation avec les figures jointes, parmi lesquelles :

  • la figure 1 représente une vue partielle en bout d'un rayonnage selon la présente invention ;
  • la figure 2 représente une vue de dessus d'une étagère posée entre des montants verticaux, avant l'insertion des pièces de blocage en coin ;
  • la figure 3 représente une demi-vue en coupe longitudinale selon l'axe 1-1 de la figure 2 ; et
  • la figure 4 représente une vue en perspective d'une pièce de blocage en coin.
Other characteristics and advantages of the present invention will emerge from the following description of particular embodiments, given in conjunction with the attached figures, among which:
  • Figure 1 shows a partial end view of a rack according to the present invention;
  • FIG. 2 shows a top view of a shelf placed between vertical uprights, before the insertion of the corner blocking pieces;
  • 3 shows a half view in longitudinal section along the axis 1-1 of Figure 2; and
  • Figure 4 shows a perspective view of a corner blocking piece.

Les figures 1 à 4 représentent un mode de réalisation dans lequel le rayonnage comprend quatre montants verticaux 1, 2, 3 et 4, délimitant une surface rectangulaire admettant un axe longitudinal 1-1. Des traverses telles que la traverse 5 relient respectivement les montants 1 et 2, 3 et 4 pour former deux cadres limitant le rayonnage. Les montants 1 et 4 peuvent être reliés par des traverses obliques non représentées sur les figures, améliorant de façon connue la rigidité du rayonnage.Figures 1 to 4 show an embodiment in which the shelving comprises four vertical uprights 1, 2, 3 and 4, delimiting a rectangular surface admitting a longitudinal axis 1-1. Cross members such as cross member 5 respectively connect the uprights 1 and 2, 3 and 4 to form two frames limiting the shelving. The uprights 1 and 4 can be connected by oblique crosspieces not shown in the figures, improving in a known manner the rigidity of the shelving.

Les montants 1 à 4 sont de section sensiblement rectangulaire, et sont pratiquement identiques. Ils comprennent chacun deux faces longitudinales 6 et 7, c'est-à-dire parallèles à l'axe longitudinal 1-1 du rayonnage, et deux faces transversales 8 et 9, c'est-à-dire parallèles à l'axe transversal de l'ensemble. Les faces longitudinales 7 sont disposées vers l'intérieur du rayonnage, et les faces transversales 9 également. De la sorte, les faces 7 des montants 1 et 2 sont opposées l'une à l'autre, et les faces 9 des montants 1 et 4 sont également opposées l'une à l'autre.The uprights 1 to 4 are of substantially rectangular section, and are practically identical. They each comprise two longitudinal faces 6 and 7, that is to say parallel to the longitudinal axis 1-1 of the shelving, and two transverse faces 8 and 9, that is to say parallel to the transverse axis from the whole. The longitudinal faces 7 are arranged towards the inside of the shelving, and the transverse faces 9 also. In this way, the faces 7 of the uprights 1 and 2 are opposite to each other, and the faces 9 of the uprights 1 and 4 are also opposite to each other.

Les montants 1 à 4 étant positionnés verticalement, on dispose les étagères telles que l'étagère 10 entre les montants, posée sur quatre taquets 11 rapportés sur les faces transversales intérieures 9 des montants.The uprights 1 to 4 being positioned vertically, the shelves are arranged such as the shelf 10 between the uprights, placed on four tabs 11 attached to the internal transverse faces 9 of the uprights.

Les faces longitudinales intérieures 7 des montants comportent une rainure verticale médiane 12 à profil en V. On pourra notamment prévoir des rainures occupant toute la largeur de la face 7. et dont les deux parois forment un angle de cent vingt degrés environ.The inner longitudinal faces 7 of the uprights have a vertical vertical groove 12 with a V-profile. In particular, it is possible to provide grooves occupying the entire width of the face 7. and the two walls of which form an angle of approximately one hundred and twenty degrees.

Les étagères 10 comportent à chaque extrémité un prolongement longitudinal, respectivement 13 et 14, s'engageant entre les montants respectifs 1 et 2. 3 et 4. Dans le cas d'une étagère 10 réalisée en bois, l'étagère elle-même est découpée avec le fil du bois disposé dans le sens longitudinal. Il peut être alors préférable de réaliser les prolongements 13 et 14 en rapportant en bout d'étagère des alèses en bois dont le fil est disposé transversalement. Cette disposition assure une bonne tenue en bout du bois de l'étagère 10, et évite sa déformation. En outre, la réalisation de l'étagère est ainsi plus facile.The shelves 10 have at each end a longitudinal extension, respectively 13 and 14, engaging between the respective uprights 1 and 2. 3 and 4. In the case of a shelf 10 made of wood, the shelf itself is cut with the wood grain arranged in the longitudinal direction. It may then be preferable to make the extensions 13 and 14 by bringing wooden mattress covers, the wire of which is arranged transversely, at the end of the shelf. This arrangement ensures good hold at the end of the wood of the shelf 10, and prevents its deformation. In addition, the realization of the shelf is thus easier.

Les prolongements 13 et 14 ont une longueur 1 inférieure à la moitié de l'épaisseur des montants prise dans le sens longitudinal des étagères, de sorte que deux étagères 10 et 10a peuvent être mises bout à bout comme le représente la figure 2. Chacun des prolongements longitudinaux comporte sur l'un de ses côtés une nervure verticale 15 conformée pour s'engager dans une rainure verticale 12 des montants. Pour cela, la tranche de l'étagère 10 forme avec le côté du prolongement 13 un dièdre rentrant dont l'angle est le même que celui de la face 9 et de la face adjacente de la rainure 12 du montant.The extensions 13 and 14 have a length 1 less than half the thickness of the uprights taken in the longitudinal direction of the shelves, so that two shelves 10 and 10a can be placed end to end as shown in Figure 2. Each of the longitudinal extensions comprises on one of its sides a vertical rib 15 shaped to engage in a vertical groove 12 of the uprights. For this, the edge of the shelf 10 forms with the side of the extension 13 a re-entrant dihedral whose angle is the same as that of the face 9 and of the adjacent face of the groove 12 of the upright.

Le côté opposé des prolongements, par exemple du prolongement 14, est oblique et comporte une rainure 16 opposable à une rainure verticale 12 d'un montant pour définir un logement 17 en forme de coin.The opposite side of the extensions, for example of the extension 14, is oblique and has a groove 16 opposable to a vertical groove 12 of an upright to define a housing 17 in the form of a corner.

Des pièces de blocage en forme de coin 18 sont conformées pour s'insérer dans le logement 17 entre la rainure verticale 12 d'un montant et la rainure opposée 16 du prolongement longitudinal 14 d'étagère.Wedge-shaped locking pieces 18 are shaped to fit into the housing 17 between the vertical groove 12 of an upright and the opposite groove 16 of the longitudinal extension 14 of the shelf.

Dans le mode de réalisation représenté sur les figures, et notamment sur la figure 4, la pièce de blocage en forme de coin 18 comporte deux faces supérieures 19 et inférieures 20 parallèles et séparées d'une hauteur sensiblement égale à l'épaisseur de l'étagère 10. Les faces avant 21 et arrière 22 sont parallèles entre elles et perpendiculaires à la face supérieure 18. Une première face latérale 23, perpendiculaire à la face supérieure 18, forme avec la face avant 21 un angle correspondant à l'inclinaison des parois de rainure 12 contre laquelle elle est destinée à venir porter. La seconde face latérale 24 forme avec la première face latérale 23 un dièdre dont le sommet est parallèle aux plans des faces supérieures 19 et inférieures 20, avec un angle de dix degrés par exemple. Cette inclinaison correspond à l'inclinaison de la rainure 16 dans laquelle elle doit s'insérer.In the embodiment shown in the figures, and in particular in Figure 4, the wedge-shaped blocking piece 18 has two upper 19 and lower 20 faces parallel and separated by a height substantially equal to the thickness of the shelf 10. The front 21 and rear 22 faces are mutually parallel and perpendicular to the upper face 18. A first lateral face 23, perpendicular to the upper face 18, forms with the front face 21 an angle corresponding to the inclination of the walls groove 12 against which it is intended to come to bear. The second lateral face 24 forms with the first lateral face 23 a dihedral whose apex is parallel to the planes of the upper 19 and lower 20 faces, with an angle of ten degrees for example. This inclination corresponds to the inclination of the groove 16 in which it must be inserted.

On dispose l'étagère 10 entre les montants de façon que les rainures 16 forment un logement 17 conique ouvert vers le haut. La fixation de l'étagère 10 s'effectue en introduisant les pièces de blocage en forme de coin 18 dans les logements 17, avec la face latérale oblique 24 en appui contre le prolongement longitudinal 13 ou 14, et la face latérale 23 en appui dans la rainure verticale 12 du montant.The shelf 10 is placed between the uprights so that the grooves 16 form a conical housing 17 open upwards. The shelf 10 is fixed by inserting the wedge-shaped locking pieces 18 into the housings 17, with the oblique lateral face 24 bearing against the longitudinal extension 13 or 14, and the lateral face 23 bearing in the vertical groove 12 of the upright.

Comme le représente la figure 2, il est préférable que les étagères 10 admettent un plan de symétrie transversale II-ll, de façon que les logements 17 se trouvent d'un même côté de l'axe de symétrie longitudinal I-I. Ainsi, les pièces de blocage en forme de coin 18 sont peu visibles de l'utilisateur, étant disposées derrière deux montants 2 et 3 qui les cachent si l'utilisateur dispose ces montants à l'avant du rayonnage. En outre, on évite les imperfections de blocage éventuelles qui se produiraient si les pièces en forme de coin étaient disposées de façon croisée.As shown in Figure 2, it is preferable that the shelves 10 admit a plane of transverse symmetry II-11, so that the housings 17 are on the same side of the longitudinal axis of symmetry II. So the pieces of wedge-shaped blocking 18 are hardly visible to the user, being arranged behind two uprights 2 and 3 which hide them if the user has these uprights at the front of the shelving. In addition, possible blocking imperfections which would occur if the wedge-shaped parts were arranged in a crossed manner are avoided.

Lors de l'introduction des pièces de blocage en forme de coin 18, l'étagère 10 est repoussée et les prolongements 13 et 14 viennent porter dans les rainures 12 des montants 1 et 4. Ainsi, l'étagère est maintenue dans un sens longitudinal par la forme en queue d'aronde des prolongements 13 et 14 insérés entre les montants correspondants, maintenue dans le sens transversal II-II par les pièces de blocage supprimant le jeu entre les prolongements 13 ou 14 et les montants correspondants dans le sens transversal, et bloquée dans le sens vertical par les frottements entre ces mêmes prolongements 13 ou 14 et les parois des rainures 12 correspondantes.During the introduction of the wedge-shaped locking pieces 18, the shelf 10 is pushed back and the extensions 13 and 14 come to bear in the grooves 12 of the uprights 1 and 4. Thus, the shelf is held in a longitudinal direction by the dovetail shape of the extensions 13 and 14 inserted between the corresponding uprights, held in the transverse direction II-II by the locking pieces eliminating the play between the extensions 13 or 14 and the corresponding uprights in the transverse direction, and blocked in the vertical direction by the friction between these same extensions 13 or 14 and the walls of the corresponding grooves 12.

Le Demandeur a pu constater que les étagères contribuent de façon importante à la rigidité du rayonnage. En effet, contrairement à ce qui se passe dans tous les dispositifs démontables connus, la disposition de deux ou trois rayonnages sur les montants suffit à rendre l'ensemble assez rigide pour tenir en position verticale sans nécessiter de traverses croisées entre les montants 1 et 4. Cela facilite ainsi le montage des rayonnages lorsqu'ils sont destinés à la seule exposition dans un magasin de vente de meubles, puisqu'il est alors inutile de placer les traverses obliques.The Applicant has been able to observe that the shelves contribute significantly to the rigidity of the shelving. In fact, contrary to what happens in all known removable devices, the arrangement of two or three shelves on the uprights is enough to make the assembly rigid enough to hold in the vertical position without requiring cross ties between the uprights 1 and 4 This thus facilitates the assembly of the shelving when they are intended for the sole display in a furniture sales store, since it is then unnecessary to place the oblique crosspieces.

La distance entre les faces avant 21 et arrière 22 de la pièce de blocage en forme de coin 18 peut être choisie de préférence égale à la longueur des prolongements 13 ou 14, de sorte que deux pièces en forme de coin 18 peuvent être insérées dans la même rainure 12 pour tenir deux étagères successives 10 et 10a.The distance between the front 21 and rear 22 faces of the wedge-shaped blocking piece 18 can preferably be chosen equal to the length of the extensions 13 or 14, so that two wedge-shaped pieces 18 can be inserted into the same groove 12 to hold two successive shelves 10 and 10a.

Le mode de réalisation décrit précédemment est particulièrement simple, et adapté pour la construction de rayonnages en bois peu onéreux. Des variantes sont toutefois possibles. Par exemple, d'autres formes de rainures 12 peuvent être utilisées, notamment à profil circulaire ou polygonal.The embodiment described above is particularly simple, and suitable for the construction of inexpensive wooden shelving. Variations are however possible. For example, other forms of grooves 12 can be used, in particular with a circular or polygonal profile.

On peut également utiliser des étagères 10 d'une seule pièce, en découpant la pièce aux quatre coins pour former les prolongements 13 et 14.One can also use shelves 10 in one piece, by cutting the piece at the four corners to form the extensions 13 and 14.

On peut également, sans sortir du cadre de la présente invention, définir des rayonnages dans lesquels les montants sont tenus par les étagères, sans l'aide de traverses 5. Pour cela on prévoit, de chaque côté de l'étagère 10, de sectionner les prolongements 13 et 14 en plusieurs prolongements séparés les uns des autres et entre lesquels sont insérés des montants, des pièces de blocage en forme de coin venant s'insérer entre les prolongements et les montants correspondants. Les montants intermédiaires peuvent alors comporter de préférence des rainures sur leurs deux faces longitudinales 6 et 7.It is also possible, without departing from the scope of the present invention, to define shelves in which the uprights are held by the shelves, without the aid of crosspieces 5. For this, provision is made, on each side of the shelf 10, to cut the extensions 13 and 14 in several extensions separated from each other and between which are inserted uprights, wedge-shaped blocking parts being inserted between the extensions and the corresponding amounts. The intermediate uprights can then preferably have grooves on their two longitudinal faces 6 and 7.

La longueur 1 des prolongements 13 et 14 peut être augmentée dans le cas où l'on ne désire pas disposer des étagères 10 et 10a successives.The length 1 of the extensions 13 and 14 can be increased in the case where it is not desired to have successive shelves 10 and 10a.

Les rainures verticales 12 des montants peuvent servir également pour adapter des panneaux ou autres accessoires sur les montants, auxquels ils sont alors solidarisés par des organes s'engageant dans les rainures 12.The vertical grooves 12 of the uprights can also be used to adapt panels or other accessories to the uprights, to which they are then secured by members engaging in the grooves 12.

En particulier on peut rapporter, sur les montants, des glissières à tiroir, ou des tablettes-support courtes, adaptées par les mêmes moyens d'assemblage que les étagères. Les glissières ou tablettes reposent sur des taquets 11 et comportent, comme le représente la figure 2 selon la ligne en pointillés 30, un prolongement longitudinal 14, une nervure latérale 15, une rainure latérale 16 recevant une pièce de blocage 18 en forme de coin.In particular, it is possible to attach drawer slides or short support shelves to the uprights, adapted by the same assembly means as the shelves. The slides or shelves rest on tabs 11 and comprise, as shown in FIG. 2 along the dotted line 30, a longitudinal extension 14, a lateral rib 15, a lateral groove 16 receiving a blocking piece 18 in the form of a wedge.
