Table pour eeolier. La px-esente invention a pour objet une table pour kolier, presentant un Plateau et deux montants comprenant chacun deux ele- ments ä emboitement telescopique, caract6- risee par 1e fait que 1'un des elements de eha- eun des montants est pourvu dune creni.ail- lere en engagement avec un pignon que Porte 1'autre element, 1'el6ment superieur de cha- que montant comprenant deux Parties assern- blees au moyen d'un pivot, l'une de ces Par ties, portant 1e Plateau de la table, kant sus- ceptible d'etre inclink et maintenue en place par rapport ä 1'autre au moyen d'un dispo- sitif comprenant au moins une pike en forme de secteur, cette pike pr6sentant une coulisse dans laquelle est destine ä se deplacer un guide. School table. The subject of the present invention is a school table, having a top and two uprights each comprising two elements with telescopic interlocking, characterized by the fact that one of the elements of each of the uprights is provided with a creni.ailler in engagement with a pinion that carries the other element, the upper element of each upright comprising two Parts assembled by means of a pivot, one of these Parts, carrying the 1st Tray of the table, kant capable of being tilted and held in place relative to the other by means of a device comprising at least one sector-shaped pike, this pike having a slide in which is intended to to move a guide.

Le dessin annex6 montre, ä. titre d'exem- ple, une forme d'exkution de la table objet de 1'invention. The appendix6 drawing shows, ä. By way of example, a form of execution of the table object of the invention.

La fig. 1 en est une vue laterale, et la fig. 2 en est une vue de face. fig. 1 is a side view, and FIG. 2 is a front view.

La table pour ecolier representee com- prend deux montants 1 et 2, en fonte, por- tant un Plateau 3 en bois; chacun de ces montants 1 et 2 comprend un 06ment inf6- rieur 4 presentant un pied 5 et un tube 6 portant un pignon dente 7 fixe ä un axe com- mun 8; ce dernier est monte sur les deux tubes 6 et est pourvu ä chacune de ses extre- mites d'un volant 9 permettant de 1'action- ner rotativement. The schoolboy table represented comprises two uprights 1 and 2, in cast iron, carrying a tray 3 in wood; each of these uprights 1 and 2 comprises a lower element 4 having a foot 5 and a tube 6 carrying a toothed pinion 7 fixed to a common axis 8; the latter is mounted on the two tubes 6 and is provided at each of its ends with a flywheel 9 enabling it to be actuated in rotation.

Dans chacun des tubes 6 est engagee une cremaillere 10 faisant Partie d'un element superieur correspondant 11 comprenant deux Parties 12 et 13 assemblees par un pivot 14 et par un dispositif 15; chacun des elements 11 Porte une equerre mkallique 16 et une vis formant guide 17 faisant Partie du dispo- sitif 15; ce dernier comprend, en outre, une pike 18 courbae en forme de secteur, dont Tune des extremites est raccordee ä une bar rette 19 et dont 1'autre extremite est fixee ä la Partie 13 portant 1e Plateau 3, cette pike 18 presentant une coulisse 20 dann laquelle est engag6 1e guide 17; ce dernier est pourvu d'un 6crou 21 permettant d'immobiliser la pike 15 et, par consequent, la Partie 13 dann une Position inclinee determinee; la barrette 1.9 est montee rotativement sur 1e pivot 14. In each of the tubes 6 is engaged a rack 10 forming part of a corresponding upper element 11 comprising two parts 12 and 13 assembled by a pivot 14 and by a device 15; each of the elements 11 carries a metal bracket 16 and a screw forming a guide 17 forming part of the device 15; the latter further comprises a bent pike 18 in the shape of a sector, one of the ends of which is connected to a bar 19 and the other end of which is fixed to the Part 13 carrying the 1st Tray 3, this pike 18 having a slide 20 in which is engaged the first guide 17; the latter is provided with a 6crou 21 to immobilize the pike 15 and, therefore, the Part 13 in a determined inclined position; the bar 1.9 is rotatably mounted on the first pivot 14.

Dans la coulisse 18 est serre un butoir 26 qui est destine ä venir en contact avec 1e guide 17 pour limiter 1'inclinaison du Plateau 3, ce butoir 26 pouvant etre deplace. In the slide 18 is clamped a stopper 26 which is intended to come into contact with the first guide 17 to limit the inclination of the plate 3, this stopper 26 being able to be moved.

L'61ement inf6rieur 4 de chaque montant est pourvu dune<RTI ID="0001.0273" WI="5" HE="4" LX="1370" LY="1765"> vis darret 27 qui permet d'immobiliser la cr6maillere 10 correspon- dante ä une hattteur determinee; cette vis est egalement utilis6e pour eliminer 1e jeu exis- tant entre l'e16ment 4 et la cremaillere 10. The lower element 4 of each upright is provided with a <RTI ID="0001.0273" WI="5" HE="4" LX="1370" LY="1765"> stop screw 27 which makes it possible to immobilize the rack 10 corresponding to a determined height; this screw is also used to eliminate the play existing between element 4 and rack 10.

Les deux Parties 13 de chaque montant possedent deux douilles 22 en regard l'une de 1'autre, dans lesquelles est fixee une Barre d'assemblage 23; de meme, les elements infe- rieurs 4 sont relies au moyen dune Barre 24. Les equerres 16 sont disposees en regard l'une de 1'autre et sont utilisees pour supporter un rayon en bois 25. Pour augmenter ou diminuer la hauteur du Plateau 3, il suffit, apAs avoir desserre la vis darret 27, d'actionner rotativement les volants 9 qui, par 1'intermediaire des pignons 7, agissent sur les cremailleres 10, tandis que pour ineliner 1e Plateau 3, an 1e fait pivoter autour du pivot 4 apres avoir devisse 1'eerou 17, qui est ä nouveau visse lorsque 1'inelinai- son desiree est atteinte. The two Parts 13 of each upright have two sockets 22 facing each other, in which is fixed an assembly bar 23; similarly, the lower elements 4 are connected by means of a bar 24. The brackets 16 are arranged facing each other and are used to support a wooden shelf 25. To increase or decrease the height of the top 3, it suffices, after having loosened the stop screw 27, to actuate the flywheels 9 in rotation which, through the intermediary of the pinions 7, act on the racks 10, while to line the first plate 3, the first year rotates around the pivot 4 after having unscrewed the screw 17, which is screwed again when the desired inclination is reached.

Il est prevu dans une variante d'ex6cu- tion de fixer un seul volant ä laxe 8 ou une manivelle amovible. Provision is made in a variant embodiment to attach a single flywheel to the axis 8 or a removable crank.
