External chassis device with internal mobile anchorage systems, positioning and automatic pre-fire retention system for long arms

Abstract

External chassis device with internal mobile anchorage systems, positioning and automatic pre-fire retention system for tong arms comprised of external chassis, mobile anchorage by means of internal sliding rings, automatic positioning system by means of a pin and an arm retention system by means of a set of guides and elastic rings integrated in the sliding rings (B) which attach to the body of an arm (D), leaving the barrel free, with free telescopic movement inside an external chassis (A). It also has a positioning pin (G) to block the movement of the arm load and some guide slots (F) for retaining the arm in a fixed position before firing. Elastic rings (H) and screws (I) prevent the rotation of the sliding rings (B) and therefore of the arm (D) inside the chassis (A).

1 . External chassis device with internal mobile anchorage systems, positioning and automatic pre-fire retention system for long arms comprised of external chassis, mobile anchorage by means of internal sliding rings, automatic positioning system by means of a pin and an arm retention system by means of a set of guides and elastic rings integrated in the sliding rings, characterised by the existence of one or more sliding rings (B) which attach to the body of an existing arm (D) without modifying it, leaving the barrel free, with free telescopic movement inside an external chassis (A). 
     
     
         2 . External chassis device with internal mobile anchorage systems, positioning and automatic pre-fire retention system for long arms, according to  claim 1 , characterised in that the chassis (A) has a positioning pin (G) located in the chassis (A) which blocks the movement of the arm load, changing its direction of movement and positioning the arm (D) in front of the retention system (H and I), which prevents the movement of the arm (D) before firing. 
     
     
         3 . External chassis device with internal mobile anchorage systems, positioning and automatic pre-fire retention system for long arms, according to  claim 1 , characterised in that it has guide slots (F) integrated in the sliding rings (B), with a special profile with throttle, which allows, in conjunction with the elastic rings (H) and screws (I), the retention of the arm in a fixed position before firing. 
     
     
         4 . External chassis device with internal mobile anchorage systems, positioning and automatic retention prior to firing for long arms, according to  claim 1 , characterised in that the existence of the set of guides (F) integrated in the sliding rings (B), elastic rings (H) and screws (I) that prevent the rotation movement of the sliding rings (B) and therefore of the arm (D) inside the chassis (A).
