IL37395A - Tripod mounting for an infantry weapon - Google Patents

Abstract

A tripod mounting for suppprting a projectile launching device has an upright mast and a pair of arms pivotally connected to the mast for vertical swinging movement relative to the mast in vertical planes that are perpendicular to each other. The arms are lockable in vertically adjustable positions. The mast carries the projectile launching device at its upper end; and the tripod can be levelled, that is, the mast made precisely vertical, by only two adjustments, one for each arm, instead of by successive approximations as in previous devices that have two vertically swingable arms whose planes of movement are not perpendicular to each other.
