| 摘要 | PURPOSE:To improve the operability of a lock mechanism upon opening and/or closing bipod by a method wherein one of the bipod is provided with a lock pin, to which an operating piece from which a cam is projected is attached, at the pivoting base thereof while the bipod of opposite side is provided with a lock plate, extended from a pivoting piece. CONSTITUTION:When the bipod is carried while being closed, the leg closing lock surface 21B of a lock plate 21 is hooked to the projected part of a lock pin 14 and an energizing force generated by a spring 10 is controlled whereby the leg rods 2, 2A are locked in the closed state without opening the bipod. When the bipod is attached to a firearm, an operating piece 15 is turned clockwise, then, a slanted lifting surface 17 is engaged with the side wall 13A of a cam groove 13 and is slid upward whereby the lock pin 14 is lifted up while pressing another spring 20, the tip end of the lock pin 14, being projected so far, is positioned in the same plane as the side surface of breech side or inserted slightly into an inserting hole 12 to release locking and, therefore, the bipod rods 2, 2A are opened by the force of the spring 10. When the bipod 2, 2A of the mounted legs 1 are to be locked, the pivoted operating piece 15 should be turned reversely. | ||||||
