GUN CARTRIDGE FOR MACHINE GUN OR EQUIVALENT SUPPORTED BY FORK WITH CONTINUOUSLY VARIABLE ADJUSTMENT MEANS OF SIGHT ANGLE FOR UPPER TURNING ARM

摘要

A gun mount e.g. for a machine gun supported by a fork comprises two mutually hinged swivel arms (2 and 3) in staggered position the one at a higher level than the other and designed to rotate around vertical axes (30, 31). The lower swivel arm (2) has a vertical pivot journal at its free end to be mounted in a pivot bearing (1). The upper swivel arm (3) is formed as a parallelogram connection for vertical adjustment of the fork (22) designed to support the weapon at the free end of the parallelogram connection. The forced vertical adjustment of the parallelogram connection is provided by means of at least one rod mechanism (15, 16, 17), which is mounted between two of the parallelogram sides and has a length adjustable in a controllable way.
