Abstract

Le problème décrit par la présente invention est de fournir un lit ayant des rails latéraux, qui permet de changer les positions et les orientations pour fixer les rails latéraux au corps du lit mais ne permet pas de changer des rails latéraux à fixer à un corps de lit dans une orientation inverse à des positions où l'utilisation des rails latéraux dans l'orientation inverse serait inappropriée. [Solution] la présente invention comprend : un corps de lit ayant une pluralité de trous d'insertion dans des parties d'extrémité latérales de celui-ci; et une pluralité de rails latéraux ayant des parties d'insertion de fixation. Dans la pluralité de rails latéraux, une forme externe d'une section transversale horizontale de chaque partie d'insertion de fixation et une forme ayant une symétrie ponctuelle avec une telle forme externe comprend au moins deux formes différentes qui ne sont pas complètement identiques. Il est prévu un premier trou d'insertion qui englobe qu'une seule forme prescrite parmi les formes extérieures des sections transversales horizontales des pièces d'insertion de fixation et des formes ayant une symétrie ponctuelle avec de telles formes extérieures, et en conséquence, seule la partie d'insertion de fixation qui englobe cette forme peut être insérée dans et fixée par celle-ci. Un second trou d'insertion est prévu, lequel englobe une forme extérieure produite par superposition d'au moins deux formes, parmi les formes externes des sections transversales horizontales des parties d'insertion de fixation et les formes ayant une symétrie ponctuelle avec de telles formes externes, et en conséquence, des pièces d'insertion de fixation de différentes formes peuvent être insérées dans et fixées de ce fait.
