Definitions

  • the present invention generally relates to firearms and more particularly to a high performance semi-automatic pistol.
  • Uzi In recent years in the firearm industry the name Uzi has been associated with a certain type of machine gun which was used by the Israeli army. The reputation of the Uzi firearm was that it is simple in construction, and thus easily assembled and disassembled and operable under adverse conditions. For several years a 9 mm Uzi semi-automatic carbine has been sold in large numbers in the U.S. The dimensional features of the Uzi carbine from fore to aft are a barrel, main body and collapsible butt of respective dimensions of 210 mm, 370 mm and 215 mm.
  • BE-A-541156 discloses firearms having a striker assembly comprising a striker pin supported by a reciprocable plate with a return spring aft of the plate. This is the document referred to in the preamble of claim 1.
  • BE-A-398680 and DE-C-300133 describes firearms in which the striker assembly comprises a cylindrical sleeve aft of the striker pin accommodating a return spring in alignment with the striker.
  • the body of the firearm must be so designed as to make allowance for the fact that in the cocked position of the striker assembly the length of the compressed return spring adds to that of the striker pin. It is therefore the object of the present invention to provide a semi-automatic pistol with such a design of the striker assembly that the body may be shortened.
  • this object is achieved in accordance with the present invention in that the striker assembly is fitted with a sleeve laterally removed from the striker pin and adapted to accommodate the striker return spring in the cocked position.
  • the sear lever frees the striker assembly.
  • the latter is spring biased by a striker assembly return spring to be driven toward the fore end of the weapon whereat a bullet to be fired had been lodged in the bore.
  • a striker assembly return spring As the striking or firing pin, provided on the striker assembly, hits the bullet's detonator it causes the shell to be fired.
  • the gases drive the bolt aft until the force of a bolt return spring drives the bolt forward.
  • the bolt feeds a new bullet from the magazine into the chamber and places it in the firing position.
  • the striker assembly the bolt drives it aft.
  • the sear lever prevents the striker assembly from moving fore until the trigger is pressed once more.
  • the striker assembly 12 includes a plate 15 which is disposed in a plane perpendicular to the axis of the weapon, represented by arrow 14. Its opposite sides 15f and 15a designate its directions of travel, i.e. fore and aft. Shown extending from fore side 15f is a striker 16, the tip of which 16t acts as the firing pin. A guide arm 18 extends from one end of the plate 15. Guide arm 18 usually slides under the weapon's bolt 19 to guide the striker 16 into its related hole in the bolt.
  • a generally cylindrically shaped post 20 extends perpendicularly from side 15a through hole 20a in the plate 15. The function of this post is to support one end of a striker assembly return spring 22.
  • the aft end of spring 22, as well as the aft end of a bolt return spring 24 are supported by aft block 13.
  • the fore end of spring 24 extends into the carbine's bolt 19 through hole 19a.
  • the distance between the sides of the body near the fore end is reduced to accommodate a handgrip.
  • the width is less than the bolt width.
  • the bolt cannot travel to the fore end of the body, thereby further increasing the required body length, to that presently used, on the order of 370 mm. It is to greatly reduce the required body length, that the present invention is directed.
  • the reduced body length of the Uzi carbine enables the use of its basic mechanism to a semi-automatic pistol.
  • a novel striker assembly is provided so that effectively the bolt is free to travel aft up to practically the rear end of the body. It is this feature which greatly contributes to body length reduction.
  • This aspect of the invention may best be described in connection with Figs. 2 and 3 wherein elements like those previously described are designated by like numerals.
  • the striker 16 with tip 16t is the same as in the prior art. It is supported by the plate 15 and points toward bolt 19. Likewise a guide arm 18 is included. The major differences however are in the manner in which the striker assembly return spring 22 is supported. Basically the post 20 which supports the spring does not extend aft of the plate, as in Fig 1. Rather it extend fore toward the bolt from a thin end plate 30. The spring 22 is wound about the post and through a hole 31 in plate 15, extends into a hollow sleeve 32, closed at its fore end 32f. As to the bolt return spring 24 it is wound about a long post 24p which is also supported at the aft end by plate 30. The post 24p with spring 24 extend through hole 33 in plate 15 and into bolt 19 through hole 19a.
  • a third aspect of body length reduction is achieved by forming the body so that its walls from back to front are parallel and of equal distance. That is as viewed from the top of the body, it is in the shape of a rectangle.
  • the bolt is urged fore by its spring 24 it effectively reaches the front end of the body to which the barrel is threaded.
  • total use is made of the body which can be made of minimum needed length. It is such body utilization that has enabled the highly popular Uzi carbine to be converted into a semi-automatic pistol.
