CARRIAGE COUPLING DEVICE FOR ARTICLE CARRYING DEVICE

Japanese Patent JP3309059

B

PROBLEM TO BE SOLVED: To prevent an interference of a stacked part of the front and rear ends of a guard plate for front and rear carriages by connecting a clearance space between the front and rear carriages to the both ends of the guard plate for covering a coupling rod in such a state as being loosely moved in the coupling position of the both ends of the coupling rod.
SOLUTION: When front and rear carriages 1, 1 coupled with a coupling rod 4 travel an upward or downward curved path, the both ends of the coupling rod 4 and the both ends 6, 6 of a guard plate 6 are coupled with the same positions of the front and rear carriages 1, 1 respectively so that the coupling rod 4 and the guard plate 6 have the same bending center to the carriage 1. Therefore the lengths of the chords of the coupling rod 4 and the guard plate 6 in the curved line part are approximately equal to each other, the front and rear carriages 1, 1 travel along the curved path without being subjected to interference of the both end parts 6, 6 of the guard plate 6, and the adjoining ends of the guard plate 6 in the traveling direction are eliminated from being interfered mutually.
