| 摘要 | 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. | ||||||
| 权利要求 | 1. A tripod mounting for supporting a projectile launching device, comprising an upright mast, a pair of arms, means connecting the arms to the mast for vertical swinging movement of the arms relative to the mast in two vertical planes that are perpendicular to each other and that intersect along an upright line that is parallel to the axis of the mast, means carried by the upper end of the mast for supporting a projectile launching device for vertical swinging movement about an axis perpendicular to the mast, means for selectively individually securing each of said arms in any of a plurality of vertically adjusted positions relative to said mast, said securing means comprising an elongated bracing member for each Of the arms, each bracing member being pivotally interconnected to the mast at one end and slidably connected to the associated arm at the other end and having locking means at said other end selectively engageable with and releasable from said associated arm, and means for selectively adjusting the length of each said bracing member. |
