Description

La présente invention a pour objet un chevalet de conférence.The present invention relates to a conference easel.

Les chavalets de conférence, et notamment ceux équipés de blocs de feuilles de papier, sont utilisés de façon courante pour l'animation de réunions.Conference chavalets, and in particular those equipped with blocks of sheets of paper, are commonly used for facilitating meetings.

Un chevalet de conférence comprend habituellement un panneau rectangulaire en tôle, en bois ou en matière synthétique, dont la face postérieure est équipée d'une part, de deux pieds télescopiques montés coulissants dans des fourreaux solidaires du panneau à proximité des bords verticaux de celui-ci et, d'autre part, d'un pied télescopique monté articulé autour d'un axe horizontal sur la paroi postérieure du panneau dans la partie centrale de celui-ci, ce pied pouvant pivoter pour former un angle avec le plan des deux premiers pieds et délimiter avec ceux-ci un trépied assurant un support stable au panneau. Le panneau est équipé, en partie haute, et sur sa face avant, de doigts permettant l'engagement d'un bloc de feuilles de papier perforées à cet effet, qui est généralement maintenu en place par une barrette amovible. Enfin, la face avant du panneau est équipée, à son extrémité inférieure, d'un auget ou plumier destiné à recevoir les crayons et autre accessoires nécessaires pour l'utilisation du chevalet.A flipchart usually comprises a rectangular panel made of sheet metal, wood or synthetic material, the rear face of which is equipped on the one hand, with two telescopic legs mounted sliding in sheaths integral with the panel near the vertical edges of the latter. ci and, on the other hand, a telescopic foot mounted articulated around a horizontal axis on the rear wall of the panel in the central part thereof, this foot being able to pivot to form an angle with the plane of the first two feet and define with them a tripod providing stable support to the panel. The panel is equipped, at the top, and on its front face, with fingers allowing the engagement of a block of perforated sheets of paper for this purpose, which is generally held in place by a removable bar. Finally, the front face of the panel is equipped, at its lower end, with a bucket or pen tray intended to receive the pencils and other accessories necessary for the use of the easel.

Un tel chevalet présente l'inconvénient d'être d'une esthétique médiocre et de se détériorer rapidement lors des diverses manipulations dont il est susceptible, en raison du fait que le panneau n'est pas protégé. Il convient, en outre, de prévoir un certain nombre de pièces spécifiques pour le montage des pieds, ainsi que pour le montage de la barrette et du plumier.Such an easel has the disadvantage of being of poor aesthetics and of deteriorating rapidly during the various manipulations of which it is susceptible, due to the fact that the panel is not protected. It is also advisable to provide a certain number of specific parts for mounting the feet, as well as for mounting the bar and the pen tray.

Enfin, la barrette étant généralement amovible, la mise en place d'un bloc de feuilles de papier est difficilement réalisée par l'intermédiaire d'une seule personne.Finally, the bar being generally removable, the establishment of a block of paper sheets is difficult to achieve by means of a single person.

La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these drawbacks.

A cet effet, le chevalet qu'elle concerne comprend un cadre constitué par un profilé présentant, vu en coupe transversale :
    - une partie principale tubulaire prolongée latéralement par,
    - un appendice équipé sur l'une de ses faces orientées perpendiculairement à la partie principale, de moyens de montage d'un panneau, et
    - sur sa face en bout, de moyens d'articulation d'un volet susceptible d'occuper deux positions stables, respectivement, sensiblement dans le prolongement de l'appendice et perpendiculairement à celui-ci.To this end, the easel which it concerns comprises a frame constituted by a profile having, seen in cross section:
- a main tubular part extended laterally by,
an appendage equipped on one of its faces oriented perpendicular to the main part, with means for mounting a panel, and
- On its end face, means of articulation of a flap capable of occupying two stable positions, respectively, substantially in the extension of the appendix and perpendicular to it.

En pratique, quatre tronçons de profilés deux à deux identiques sont assemblés par quatre pièces d'angle pour former un cadre, dont les deux parties principales des tronçons verticaux servent à l'engagement et au coulissement de deux pieds, dont une paroi latérale de chacun des quatre tronçons de profilés sert au montage d'un panneau dont l'épaisseur et la nature sont adaptées au type de chevalet à réaliser.In practice, four identical sections of two by two sections are assembled by four corner pieces to form a frame, the two main parts of the vertical sections of which are used for the engagement and sliding of two feet, one of which has a side wall. of the four sections of profiles is used for mounting a panel whose thickness and nature are adapted to the type of easel to be produced.

En outre, les tronçons horizontaux de profilés haut et bas sont équipés d'un volet articulé en partie haute pour le profilé supérieur et d'un volet identique articulé en partie basse pour le profilé inférieur, le premier volet tenant lieu de barrette et le second volet tenant lieu de plumier.In addition, the horizontal sections of top and bottom profiles are equipped with a hinged flap in the upper part for the upper profile and an identical hinged flap in the lower part for the lower profile, the first flap serving as a bar and the second shutter in place of pencil case.

Les tronçons verticaux de profilés sont en outre équipés d'un troisième pied articulé qui occupe une position centrale.The vertical sections of profiles are also equipped with a third articulated leg which occupies a central position.

Un tel chevalet est très intéressant par son esthétique puisque le panneau est encastré entre quatre tronçons de profilés qui assurent en même temps sa protection et évitent sa détérioration lors des opérations de manipulation.Such an easel is very interesting for its aesthetics since the panel is embedded between four sections of sections which at the same time provide protection and prevent its deterioration during handling operations.

En outre, les deux pieds avant sont montés coulissants à l'intérieur des tronçons verticaux de profilés, ce qui évite la mise en oeuvre de pièces spécifiques pour leur montage et leur réglage.In addition, the two front feet are slidably mounted inside the vertical sections of profiles, which avoids the use of specific parts for their mounting and adjustment.

Enfin, un même type de volet permet de remplir à la fois les fonctions de barrette et de plumier, étant précisé que le plumier peut être maintenu dans une position stable fermée pour la position de transport et que la barrette peut être maintenue dans une position stable ouverte lors du remplacement d'un bloc de feuilles de papier.Finally, the same type of flap makes it possible to fulfill both the functions of strip and pen tray, it being specified that the pen tray can be kept in a stable position closed for the transport position and that the strip can be kept in a stable position open when replacing a block of paper sheets.

Le profilé utilisée peut être un profilé métallique ou, avantageusement. un profilé en matière synthétique qui confère une grande légèreté au chevalet.The profile used can be a metal profile or, advantageously. a profile in synthetic material which gives a great lightness to the bridge.

Avantageusement, le profilé constitutif du cadre comprend une partie principale tubulaire de section carrée, prolongée latéralement par un appendice constitué par une partie tubulaire de section rectangulaire, dont l'une des parois est dans le prolongement de l'une des parois de la partie principale, cet appendice présentant, dans sa face en bout, un évidement de forme sensiblement hémi-cyclindrique pour l'articulation d'un volet, et étant équipé d'un retour tubulaire de section sensiblement rectangulaire, ce retour délimitant, avec la partie principale du profilé et l'appendice de celui-ci, un évidement en forme générale de U.Advantageously, the profile constituting the frame comprises a main tubular part of square section, extended laterally by an appendage constituted by a tubular part of rectangular section, one of the walls of which is in the extension of one of the walls of the main part. , this appendage having, in its end face, a recess of substantially semi-cylindrical shape for the articulation of a flap, and being equipped with a tubular return of substantially rectangular section, this return delimiting, with the main part of the profile and appendage thereof, a recess in the general shape of a U.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de ce chevalet de conférence :

  • Figure 1 en est une vue en perspective ;
  • Figure 2 et 3 sont deux vues en coupe transversale et à échelle agrandie selon les lignes II-II et III-III de figure 1, respectivement de la partie supérieure et de la partie inférieure du chevalet ;
  • Figure 4 est une vue en coupe partielle de la partie supérieure du chevalet selon la ligne IV-IV de figure 1 ;
  • Figure 5 est une vue en perspective éclatée d'une extrémité d'un profilé du volet qui lui est associé et d'un pièce de liaison avec un profilé adjacent.
In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing representing, by way of nonlimiting example, an embodiment of this flipchart:
  • Figure 1 is a perspective view;
  • Figure 2 and 3 are two views in cross section and on an enlarged scale along lines II-II and III-III of Figure 1, respectively of the upper part and the lower part of the easel;
  • Figure 4 is a partial sectional view of the upper part of the bridge along the line IV-IV of Figure 1;
  • Figure 5 is an exploded perspective view of one end of a profile of the flap which is associated with it and of a connecting piece with an adjacent profile.

Le chevalet, représenté à la figure 1, comprend un cadre désigné par la référence générale 2, constitué par quatre tronçons de profilés à savoir deux tronçons horizontaux 3 et 4 haut et bas, et deux tronçons 5 verticaux.The easel, shown in Figure 1, comprises a frame designated by the general reference 2, consisting of four sections of profiles, namely two horizontal sections 3 and 4 top and bottom, and two vertical sections 5.

Les tronçons 3,4 et 5 sont réalisés à partir du même profilé et assemblés les uns aux autres par quatre pièces d'angles 6.The sections 3, 4 and 5 are produced from the same section and assembled to each other by four pieces of angles 6.

Comme cela ressort notamment des figures 2 à 4, le profilé comprend une partie principale 7 présentant, en coupe transversale, une section carrée. Cette partie principale est prolongée sur l'une de ses faces par un appendice 8 de section générale rectangulaire dont l'une des parois est dans le prolongement d'une paroi de la partie principale 7. Cet appendice est de largeur inférieur à la largeur de la partie principale 7.As is apparent in particular from Figures 2 to 4, the profile comprises a main part 7 having, in cross section, a square section. This main part is extended on one of its faces by an appendage 8 of generally rectangular section one of the walls of which is in the extension of a wall of the main part 7. This appendage is of width less than the width of the main part 7.

Dans sa face en bout, l'appendice 8 comporte un évidement 9 hémisphérique. L'appendice 8 est également équipé d'un retour 10 tubulaire et de section générale rectangulaire délimitant avec la partie principale 7 un évidement en forme générale de U, séparé en deux par une nervure longitudinale 12 de hauteur inférieure à la hauteur de l'évidement.In its end face, appendix 8 has a hemispherical recess 9. The appendix 8 is also equipped with a tubular return 10 and of generally rectangular section delimiting with the main part 7 a recess in the general shape of a U, separated in two by a longitudinal rib 12 of height less than the height of the recess .

En pratique, la partie principale 7 du profilé sert dans le cas des deux montants verticaux 5 à l'engagement de deux pieds 13 de section carrée reliés à leur extrémité inférieure par une traverse 13a. Ces pieds sont montés coulissant à l'intérieur des profilés et peuvent être bloqués dans la position souhaitée par l'intermédiaire d'un dispositif de verrouillage par coincement dont un bouton de manoeuvre 14 est représenté au dessin, ou par un dispositif de verrouillage positif.In practice, the main part 7 of the profile is used in the case of the two vertical uprights 5 for the engagement of two feet 13 of square section connected at their lower end by a cross member 13a. These feet are slidably mounted inside the profiles and can be locked in the desired position by means of a locking device by wedging, an operating button 14 of which is shown in the drawing, or by a positive locking device.

L'évidement ménagé entre le retour 10 et la partie principale 7 sert au montage d'un panneau 15. Dans le cas où ce panneau est de faible épaisseur, il est disposé entre la nervure 12 et le retour 10. Cependant, il est possible d'envisager le montage d'un panneau de plus forte épaisseur occupant la totalité de la largeur de l'évidement entre la partie principale 7 et le retour 10, et prenant appui dans ce cas sur la nervure 12.The recess formed between the return 10 and the main part 7 is used for mounting a panel 15. In the case where this panel is thin, it is disposed between the rib 12 and the return 10. However, it is possible to consider mounting a panel of greater thickness occupying the entire width of the recess between the main part 7 and the return 10, and bearing in this case on the rib 12.

Si le chevalet de conférence est utilisé comme vitrine pour la présentation d'informations, la partie principale 7 du profilé peut être équipée d'un panneau de fond non représenté au dessin, fixé sur les ailes 16 qui comporte la partie principale 7, des glaces coulissantes, transparentes, non représentées au dessin pouvant être montées à la place du panneau 15, dans les deux espaces ménagés entre la nervure centrale 12 et la partie principale 7 du profilé et le retour 12, respectivement.If the flipchart is used as a showcase for the presentation of information, the main part 7 of the profile can be equipped with a bottom panel not shown in the drawing, fixed on the wings 16 which includes the main part 7, windows sliding, transparent, not shown in the drawing which can be mounted in place of the panel 15, in the two spaces provided between the central rib 12 and the main part 7 of the profile and the return 12, respectively.

Le pied postérieur 17 est monté sur une tige horizontale dont les extrémités cylindriques sont engagées à l'intérieur de paliers solidaires des tronçons de profilés 5.The rear leg 17 is mounted on a horizontal rod, the cylindrical ends of which are engaged inside bearings integral with the sections of sections 5.

En outre, le panneau 15 est équipé de façon connue de doigts 18 faisant saillie de sa face supérieure, et destinés à l'engagement d'un bloc 19 de feuilles de papier perforées.In addition, the panel 15 is equipped in a known manner with fingers 18 projecting from its upper face, and intended for the engagement of a block 19 of perforated sheets of paper.

L'évidement 9 de chacun des tronçons de profilés haut 3 et bas 4 est destiné à l'engagement élastique d'un jonc cylindrique 20 appartenant à une pièce 22 en forme de volet et situé à proximité d'un bord de celui-ci. La partie cylindrique 20 permet le pivotement du volet 22 entre deux positions stables dans lesquelles le volet se trouve respectivement sensiblement perpendiculaire et sensiblement parallèle au panneau 15. Le maintien du volet en position perpendiculaire au panneau 15 est obtenu par coincement. Cette position permet, pour le volet haut constitutif de la barrette, un remplacement facile du bloc de papier 19 et pour le volet bas constitutif du plumier, le maintien en position ouverte de celui-ci.The recess 9 of each of the sections of top 3 and bottom sections 4 is intended for the elastic engagement of a cylindrical rod 20 belonging to a part 22 in the form of a flap and located near an edge thereof. The cylindrical part 20 allows the flap 22 to pivot between two stable positions in which the flap is respectively substantially perpendicular and substantially parallel to the panel 15. Maintaining the flap in a position perpendicular to the panel 15 is obtained by wedging. This position allows, for the top component of the bar, easy replacement of the paper block 19 and for the bottom component of the pen tray, maintaining the open position thereof.

Le maintien du volet en position parallèle au panneau est assuré par engagement élastique d'une extrémité élargie 23 que présente une aile perpendiculaire au plan du volet, dans un évidement 24 ménagé dans le retour 10 du profilé.Maintaining the flap in position parallel to the panel is ensured by elastic engagement of an enlarged end 23 that has a wing perpendicular to the plane of the flap, in a recess 24 formed in the return 10 of the profile.

Cette position assure, pour la barrette supérieure, le maintien du bloc de feuilles sur le panneau et pour le volet inférieur formant plumier le maintien en position fermée de celui-ci, en période de transport ou de non utilisation du chevalet.This position ensures, for the upper bar, the maintenance of the block of sheets on the panel and for the lower flap forming a pen tray, the maintenance in the closed position of the latter, during the transport or non-use of the easel.

Il est également à noter que le volet 22 comporte, à son extrémité opposée à celle d'articulation sur un profilé, un bec 25 faisant saillie du même côté que l'aile 23. Ce bec 25 renant appui sur le bloc de papier, permet un déchirage propre de la feuille de papier située sur la face avant du bloc, et constitue, pour le plumier, un rebord évitant tout risque de chute des crayons.It should also be noted that the flap 22 comprises, at its end opposite to that of articulation on a profile, a spout 25 protruding on the same side as the wing 23. This spout 25 resting on the paper block, allows a clean tear of the sheet of paper located on the front face of the block, and constitutes, for the pen tray, a rim avoiding any risk of falling pencils.

Comme cela est représenté à la figure 5, les quatre tronçons de profilés 3,4 et 5, sont assemblés par des pièces d'angles 6 comprenant chacune deux parties mâles de section carrée 26, destinées à être engagées dans les parties principales 7 des deux profilés à assembler et quatre parties males 27 et 28 destinées à être engagées dans les évidements 8 et 10 des deux tronçons de profilés à assembler. Il est à noter que pour des raisons de simplicité, chaque pièce d'assemblage 56 pourrait être réalisée en deux parties dont la première comporte les parties males 26 et dont l'autre comporte les parties males 27 et 28.As shown in Figure 5, the four sections of sections 3,4 and 5, are assembled by pieces of angles 6 each comprising two male parts of square section 26, intended to be engaged in the main parts 7 of the two profiles to be assembled and four male parts 27 and 28 intended to be engaged in the recesses 8 and 10 of the two sections of profiles to be assembled. It should be noted that for reasons of simplicity, each assembly part 56 could be produced in two parts, the first of which comprises the male parts 26 and the other of which comprises the male parts 27 and 28.

Avantageusement, et comme montré aux figures 1 et 4, le tronçon supérieur de profilé 3 sert de logement à deux profilés 29 de longueur légèrement inférieure à celle du tronçon 3 et de section légèrement inférieure à la moitié de la section de la partie principale 7, de manière à pouvoir toutes les deux être engagés dans cette dernière, ces deux profilés 29 traversant chacun un embout d'angle 6, de façon à pouvoir être dégagés du tronçon supérieur 3 et à former des potences permettant la fixation de feuilles de papier déjà utilisées. Les moyens de blocage de profilés 29 en position sortie et en position rentrée sont constitués pour chacun d'eux par un doigt 30 poussé par un ressort 32 et pénètrant dans un orifice 33 du tronçon de profilé 3. Les extrémités 34 de chaque profilé 29 situées du côté intérieur sont biseautées de façon à éviter qu'elles butent l'une contre l'autre lors de leur rentrée dans le tronçon de profilé 3.Advantageously, and as shown in FIGS. 1 and 4, the upper section of section 3 serves to accommodate two sections 29 of length slightly less than that of section 3 and of section slightly less than half the section of the main part 7, so as to both be able to be engaged in the latter, these two sections 29 each passing through an end piece 6, so as to be able to be released from the upper section 3 and to form brackets allowing the fixing of sheets of paper already used . The profile blocking means 29 in the extended position and in the retracted position are constituted for each of them by a finger 30 pushed by a spring 32 and penetrating into an orifice 33 of the profile section 3. The ends 34 of each profile 29 located on the inner side are bevelled so as to prevent them from abutting one another when they enter the profile section 3.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un chevalet de conférence de conception simple présentant l'avantage de comporter un cadre réalisé à partir d'un profilé tubulaire permettant le montage des différents types de panneaux et rendant possible différentes utilisations de ce chevalet, celui-ci pouvant tout aussi bien recevoir des blocs de feuilles de papier que constitue une vitrine.As is clear from the above, the invention brings a great improvement to the existing technique by providing a flipchart of simple design having the advantage of comprising a frame produced from a tubular profile allowing the mounting of the different types panels and making possible different uses of this easel, it can just as well receive blocks of sheets of paper that constitutes a display case.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce chevalet, décrite ci-dessus à titre d'exemple ; elle en embrasse, au contraire, toutes les variantes de réalisation.It goes without saying that the invention is not limited to the sole embodiment of this easel, described above by way of example; she in embraces, on the contrary, all variants.

C'est ainsi notamment que la section du profilé constitutif du cadre pourrait être différente, la partie principale de celui-ci pouvant par exemple être de section circulaire sans que l'on sorte pour autant du cadre de l'invention.Thus, in particular, the section of the profile constituting the frame could be different, the main part of the latter being able for example to be of circular section without departing from the framework of the invention.
