ABSTRACT:
Bipod mortar stand, having one support mechanism and one lifting mechanism, is disclosed. The support mechanism has two legs forming a bipod. Each leg is pivoted at one end to a bracket fastened to a central leg. Each leg has drive stops on the other end. A connecting rod connects each leg to an open ring mounted on the central leg. The ring moves up and down on the central leg and can be fastened on the central leg.
The lifting mechanism is formed by the central leg and telescoping tubes and an interior tube is integral to a locknut and an exterior tube is integral to the mortar holding structure. An intermediate tube is capable of linear movement with respect to the other two tubes. A lifting device, mounted on the intermediate tube has conic gears, one conic gear is activated from an exterior crank and the other is integral to a shank which moves with the gear box and the intermediate tube. Anti-rocking guides are arranged on the exterior tube, the intermediate tube and the shank.
The lifting mechanism raises and lowers the shaft with respect to the bipod stand, in such a way that the relative position between both always remains constant.
