Abstract

The invention relates to a device making it possible for a table-tennis table to stand on its legs by placing it in the playing position, and on its wheels in its closed position. It consists of castors 6 at the end of a strut 1 which forms the side of a parallelogram articulated by the spindles 2, 3, 4, 5, which makes it possible, without effort, to position the table on these castors by raising it and to lower it again onto its legs by moving it down.

Description

La présente invention est destinée à faciliter le déplacement des tables de tennis de table dans les salles de jeu. The present invention is intended to facilitate the movement of table tennis tables in game rooms.

Traditionnellement, les tables pourvues de roues pour leur rangement, soit restent sur leurs roues, soit ces roues doivent être mises en place manuellement par l'usager. Traditionally, tables provided with wheels for their storage, either remain on their wheels, or these wheels must be set up manually by the user.

Le procédé, selon l'invention permet de supprimer cette servitude. The method according to the invention makes it possible to eliminate this easement.

Les roues sont positionnées à l'extrémité des bras de force, rendus solidaires de la montée et de la descente des plateaux de jeu, par un système parrallélogramme. The wheels are positioned at the end of the power arms, made integral with the raising and lowering of the game boards, by a parallelogram system.

Ouverte, la tabZe repose sur ses pieds, fermée, la table se trouve sur ces roues. Open, the tabZe rests on its feet, closed, the table is on these wheels.

Les dessins annexés illustrent l'invention. La figure (1) représente la table vue de face. The accompanying drawings illustrate the invention. Figure (1) shows the table seen from the front.

La figure (2) représente la table vue de profil, table composée de deux demi-tables. Figure (2) shows the profile view table, a table made up of two half-tables.

La figure (3) représente une coupe longitudinale de la table, une moitié horisontale, l'autre relevée. Figure (3) shows a longitudinal section of the table, one horizontal, the other half raised.

Le dispositif selon l'invention comporte des pieds articulés autour de deux axes (4, 5) situés au voisinage du plateau (7). Ces pieds sont retirés dans leur partie basse par une jambe de force (1) articulée sur deux axes (2, 3) au voisinage du sol. The device according to the invention comprises feet articulated around two axes (4, 5) located in the vicinity of the plate (7). These feet are removed in their lower part by a strut (1) articulated on two axes (2, 3) in the vicinity of the ground.

Les quatres axes (2, 3, 4, 5,) forment les somments d'un parrallélogramme déformable. The four axes (2, 3, 4, 5,) form the summits of a deformable parallelogram.

Lors de la mise en position de rangement et lors du transport de la table le plateau (7) est soulevé par son extrémité (10). le pied (9) vient en appui contre le plateau (7) en prenant une position, en bout de course, légèrement inclinée vers l' intérieur par rapport à la verticale. Dans cette position la jambe de force (1) forme un angle aigü avec la supérieure du plateau 5@) et permet de ce fait, par rapport à l'axe (3), un meilleur blocage dans cette position du plateau (7). When placing in the storage position and during transport of the table, the plate (7) is raised by its end (10). the foot (9) comes to bear against the plate (7) taking a position, at the end of the stroke, slightly inclined inwards relative to the vertical. In this position the strut (1) forms an acute angle with the top of the plate 5 () and therefore allows, relative to the axis (3), better locking in this position of the plate (7).

La sécurité lors du transport s'en trouve accrue.Safety during transport is increased.

Dans Ze même temps, la roulette (6) vient en appui sur Ze soZ en soluevant le pied (8). At the same time, the caster (6) comes to bear on Ze soZ by soluting the foot (8).

Ceci est obtenu par le fait que la distance de l'axe (3) au plan orthogonal au bras de force (1) et tangent à la roulette (6) est supérieure à la distance de l'axe (3) à l'extrémité basse du pied (8).  This is obtained by the fact that the distance from the axis (3) to the plane orthogonal to the force arm (1) and tangent to the wheel (6) is greater than the distance from the axis (3) to the end lower leg (8).

Selon une réalisation préférentielle de l'invention, les axes (3, 4) solidaires des pieds (8) sont avantageusement décalés vers le bas par rapports aux axes (2, 5) de telle sorte que la hauteur en position repliée se trouve réduite, et corrélativement, que le centre de gravité de l'ensemble se trouve abaissé. According to a preferred embodiment of the invention, the axes (3, 4) integral with the feet (8) are advantageously offset downward relative to the axes (2, 5) so that the height in the folded position is reduced, and correlatively, that the center of gravity of the assembly is lowered.

Par ailleurs la force nécessaire pour soulever le plateau, en début de mise en position de transport, se trouve diminuée. Furthermore, the force required to lift the platform, at the start of the transport position, is reduced.

Le dispositif selon l'invention est destiné plus particulièrement au domaine du tennis de table, mais il s'applique d'une manière générale au secteur des tabZes pliantes.  The device according to the invention is intended more particularly for the field of table tennis, but it generally applies to the sector of folding tabs.
