Document Type and Number:
Japanese Patent JP3433206
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To conduct the supporting leg opening and closing of a supporting stand for various equipment, such as supporting leg opening and closing of a supporting stand for boom sprayer used for chemicals spraying work without need for much labor and causing excessive looseness, using a simple low-cost structure.
SOLUTION: The upper parts 21a, 21b of supporting legs 8a, 8b are jounaled to the outside right and left lower parts of a base part 9 where equipment 1 is supported and constructed so as to be folded freely at the lower surface of the base part 9. The upper ends 13a, 13b of the supporting legs 8a, 8b are brought into contact with the outside end surfaces 14a, 14b of the base part 9 while the legs are being opened, so that a prescribed opening/closing condition is maintained by the dead weight of the equipment 1. The upper ends 13a, 13b of the right and left supporting legs 8a, 8b are connected to both the ends 15a, 15b in the expanding/contracting direction of one expandable actuator 15 through link mechanisms 16a, 16b, 19a, 19b respectively.
