Abstract

La présente invention a trait à un matériel de cuisson portatif comportant un montant introduit dans le sol à proximité d'un feu direct, et une tête de commande apte à être entraînée en rotation sur le montant. La tête de commande comporte un support qui assure le support pivotant d'un bras. Une gril est suspendu depuis une extrémité du bras. Un mécanisme de commande sur la tête de commande est en contact avec le bras à proximité de son autre extrémité. Le mécanisme de commande comporte un écrou fixé au support, et une vis qui s'accouple avec l'écrou et se trouve en contact avec le bras. Grâce à la rotation de la vis, le bras pivote de manière uniforme dans le support. Le gril est suspendu à partir d'un arbre apte à être entraîné en rotation dans le bras. L'arbre est entraîné en rotation au moyen d'un moteur, entraînant ainsi la rotation du gril sur le feu. Le gril est ainsi mobile par rapport au feu selon trois degrés de liberté. Le matériel de cuisson portatif est construit avec des composants de taille relativement réduite qui sont faciles à assembler, démonter et transporter.
