DESCRIPTION:
BRIEF SUMMARY
the present invention is related to a recoil suppressing mount for a manually operated automatic weapon.
BACKGROUND OF THE INVENTION
Different designs for mounts for automatic weapons of the above mentioned type are known, partly also specially adapted for stationary or mobile supports. Known mounts, however, suffer from the drawback that the recoil forces from the weapon bring the weapon out of the sight line for the following firing. Known mounts of the above mentioned type also have been less developed with regard to quick and secure operation and for producing a series of shots very quickly.
SUMMARY OF THE INVENTION
With the recoil suppressed mount according to the present invention, however, the recoil from fired shots do not substantially effect the weapon aiming, whereby the mount may be used on different supports, such as a tripod, on rolling vehicles or caterpillars, vessels, helicopters or airplanes. With the mount according to the invention the same rate of fire is achieved independently of the angle of the weapon core line. Also a substantially lighter structure is achieved by the mount according to the present invention as compared to known structures and where the operation of the weapon is very quickly and safely and the weapon also very simple can be adjusted to the trigger mechanism of different weapons. With the recoil suppressed mount according to the invention a substantial dampening of the recoil forces is achieved, in the order of 80 to 90%.
The above described advantages and objects is obtained with the recoil suppressed mount according to the present invention as defined with the features stated in the characterizing clauses of the claims.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings
FIG. 1 discloses a side view of the recoil suppressed mount according to the present invention, with a weapon installed,
FIG. 2 discloses the mount in FIG. 1 in a top view,
FIG. 3 discloses a longitudinal section through the shock absorber in an enlarged scale and
FIG. 4 discloses a top view of the front portion of the cradle, in the same scale as FIG. 4.
DESCRIPTION OF A PREFERRED EMBODIMENT
As disclosed in FIG. 1 and 3, the mount is supported on a pivot fork 3 which is turnable secured to a fundament, not disclosed, such as a tripod. The fork 3 is turnable supporting an outer cradle 1 by means of two bearing pins 9 arranged symmetrically and in the same plane as the core line 7 of the weapon 8, whereby the axis of the bearing pins 9 being coaxial and arranged perpendicularly to the core line 7. The outer cradle 1 thereby being able to turn on the bearing pins 9 and assume a desired angle for the core line 7 in relation to the horizontal plane. By means of the pivot fork 3 support in the tripod, the outer cradle 1 can be turned around a vertical axis in relation to the tripod.
An inner cradle 2 is arranged displaceable in the outer cradle 1 by means of front and rear sliding guides. The front sliding guide is disclosed in FIG. 3 and comprises a bolt 19 secured to the outer cradle 1 and protruding through a slot 10 in the inner cradle in such a way that the inner cradle can be displaced in the longitudinal direction of the weapon a limited distance corresponding to the length of the slot, whereby plastics material 13, 14 being arranged between inner and outer cradles and between a washer under the head of the bolt and the inner cradle 2. Additionally sliding bearings 11 and 12 are arranged between the inner and outer cradle in at least one side. In this way a very accurate guiding of the reciprocating movement of the inner cradle 2 in relation to the outer cradle 1 is achieved.
Two shock absorbers 4 and 5 furthermore connect the inner and outer cradles, being arranged symmetrically to the core line 7 of the weapon, of which both are arranged in the same plane as the core line in which plane also the two bearing pins 9 are arranged. The forces transmitted to the mount by firing of the weapon thereby being transferred from the core line 7, through the two shock absorbers 4 and 5 and to th
