| 摘要 | A hand gun and a shot-type ammunition cartridge which provides a linear shot pattern. The gun includes a barrel which is pivotally mounted to the gun frame to fold the barrel against the frame for easy storage or for concealment under clothing. The barrel has a specially shaped bore which is oblong in cross section and a fanshaped muzzle to provide a planar field of fire when a shot-type gun shell is employed. A shell having a special configuration conforming to the shape of the bore cooperates with the barrel in developing an even distribution of shot in a linear shot pattern. | ||||||
| 权利要求 | 1. A hand gun comprising: a gun frame; a trigger mounted to the frame and movable with respect to the frame; firing means including a movable hammer mounted to the frame, the firing means being engaged by the movable trigger for actuation of the hammer; a gun barrel having a bore therethrough and muzzle and breech ends respectively disposed at opposite ends of said bore, the barrel being pivotally mounted to the gun frame about an axis parallel to the bore for limited pivotal displacement, the displacement positions including a first position with respect to the frame in which the breech end of the barrel registers with the hammer for firing and a second pivotal position in which the breech end is offset from registry with the hammer; and means for resiliently biasing the gun barrel away from the second position and into the first position. 2. The hand gun of claim 1 including: means connected to the gun frame for retaining the gun barrel in the first and second positions. 3. The hand gun of claim 1 including: means connected to the trigger for latching the gun barrel in the second position. 4. The hand gun of claim 3 wherein: the means for latching the gun barrel includes a latch fixedly connected to the movable trigger. 5. The hand gun of claim 4 wherein: the movable trigger is pivotally mounted in the gun frame, the pivotal displacement of the trigger including a segment between a rest position of the trigger and a firing position of the trigger; and the means for latching is connected to the trigger for releasing the gun barrel from the second position at a position of the trigger intermediate the rest position and the firing position. 6. The hand gun of claim 1 in which: the breech end of the gun barrel in the second position is sufficiently offset to one side of the gun frame to permit access to the breech end for loading. 7. A hand gun comprising: a gun frame; a trigger mounted to the frame and movable with respect to the frame; firing means including a movable hammer mounted to the frame, the firing means being engaged by the movable trigger for actuation of the hammer; a gun barrel having a bore therethrough and muzzle and breech ends respectively disposed at opposite ends of said bore, the barrel being pivotally mounted to the gun frame about an axis parallel to the bore for limited pivotal displacement, the displacement positions including a first position with respect to the frame in which the breech end of the barrel registers with the hammer for firing and a second pivotal position in which the breech end is offseT from registry with the hammer; and a breech face cover pivotally mounted to the breech end of the barrel for opening and closing the breech end of the barrel. 8. The hand gun of claim 7 including: locking means connected to the gun barrel for locking the breechface cover in a closed position with the breech end of the gun barrel. 9. The hand gun of claim 7 wherein: a firing pin is mounted in the breechface cover. 10. The hand gun of claim 9 including: means for resiliently biasing the gun barrel away from the second position and into the first position. 11. A hand gun comprising: a gun frame, said frame having a generally planar configuration; a trigger mounted to the frame and movable with respect to the frame; firing means including a movable hammer mounted to the frame, the firing means being engaged by the movable trigger for actuation of the hammer; and a gun barrel having a bore therethrough and muzzle and breech ends disposed at opposite ends of said bore, said gun barrel having a generally planar configuration and said bore having a generally oblong shape in transverse section with the dimensions of the bore in the oblong direction being greater at the muzzle end than at the breech end of the barrel, said barrel being pivotally mounted to the gun frame about an axis parallel to the bore for limited pivotal displacement, the displacement positions including a first position with respect to the frame wherein the plane of the frame and the plane of the barrel are substantially perpendicular and in which the breech end of the barrel registers with the hammer for firing, the displacement positions also including a second pivotal position in which the breech end is offset from registry with the hammer, the plane of the frame and the plane of the barrel being substantially parallel at the second position. 12. The hand gun of claim 11 wherein: the dimensions of the bore in the oblong direction along a portion of the bore adjacent the breech end of the barrel are the same. 13. The hand gun of claim 11 wherein: the dimensions of the bore in the oblong direction adjacent the muzzle increase continuously as the distance to the mouth of the muzzle decreases. 14. The hand gun of claim 11 wherein: the muzzle end of the barrel has a muzzle opening lying along an arc of a circle parallel to the plane of the barrel. 15. The hand gun of claim 11 wherein: the barrel has a fan-shaped muzzle end. 16. The hand gun of claim 15 wherein: the surface of the bore within the fan-shaped muzzle includes a plurality of tapered ridges extending radially from a point within the bore to the mouth of the muzzle. 17. The hand gun of claim 11 wherein: the breechface of the barrel includes a cutout for receiving the lip of an ammunition shell. 18. The hand gun of claim 11 including: means connected to the outer surface of the barrel for pivotally mounting the barrel to a gun frame. 19. The hand gun of claim 18 including: means for resiliently biasing the gun barrel away from the second position and into the first position. 20. A hand gun comprising: a gun frame; a trigger mounted to the frame and movable with respect to the frame; firing means including a movable hammer mounted to the frame, the firing means being engaged by the movable trigger for actuation of the hammer; a gun barrel having a bore therethrough and muzzle and breech ends disposed at opposite ends of said bore, the barrel being pivotally mounted to the gun frame about an axis parallel to the bore for limited pivotal displacement, the displacement positions including a first position with respect to the frame in which the breech end of the barrel registers with the hammer for firing and a second pivotal position in which the breech end is offset from registry with the hammer, said bore having a generally oblong shape in transverse section with the dimensions of the bore in the oblong direction being gReater at the muzzle end than at the breech end of the barrel; and a breechface cover pivotally mounted to the breech end of the barrel. 21. The hand gun of claim 20 wherein: a firing pin is secured in the breechface cover. 22. The hand gun of claim 20 wherein: a spring-loaded lock pin is mounted in the wall of the barrel at the breechface; and the breechface cover defines a locking aperture positioned to receive the lock pin at a closed position of the cover and the breech end of the barrel. |
