| 【課題】銃身支持部材と銃身との間のクリアランスにより、銃身の回転移動が常に一定とはならず、弾道もずれてしまう。 【解決手段】カウンターウェイト40が銃身10より上方にあり、支持部位であるリング61,62は銃身10の重心よりもカウンターウェイト40に近い側に位置している。銃身10がカウンターウェイト40の下方にあり、ギア30の下面側に噛合している関係上、弾丸の発射時に銃身10が後退すると、ギア30の円形の表面形状によって銃身10自体を時計回り方向に回転させようとする力が生じる。銃身10は重心位置とリング61とリング62とから時計周り方向に回転する力を受けて銃身支持部材50の内周面に対して接しているため、クリアランスにかかわらず、銃身支持部材50の内部でずれることはない。 【選択図】 図1 |

| A firearm formed by a housing, in which an assembly of a carriage und a barrel with a muzzle stop, and a breech are displaceably supported, wherein the breech is equipped with a return spring that is supported on the rear support surface of the housing, has a counter weight (6) displaceably disposed in an oblong space located between the housing (1) and the carriage (2), on the support surface of which counter weight the rear end of the return spring (7) is supported, and which is seated in the front position thereof on a front stop surface (19) of the carriage (2). The breech (5) is seated in the rear position thereof on a rear stop surface (17) of the carriage (2), the return spring (7) is also supported on a front support surface (13) of the housing (1) at the front end in the front position of the breech (5), and a transfer element protrudes into the path of the breech (5), the transfer element being simultaneously supported on the carriage (2) and on the counter weight (6), and in the outer position thereof pushing the counter weight (6) against a front stop surface (19) of the carriage (2). | ||||||
| 3 | Recoil attenuating mechanism for a firearm | US15049728 | 2016-02-22 | US09897403B2 | 2018-02-20 | Faisal Kedairy |
| The present invention relates to firearms, especially to guns, and more particularly to a system for attenuating recoil, reducing muzzle climb and increasing accuracy. The invention provides a recoil attenuating mechanism that is an improvement on the well-known and widely used Browning tilting barrel system which is used mostly in semi-automatic pistols. The recoil attenuation is achieved by redirecting and manipulating the forces of the recoil of the slide of the pistol to a different axis than what is the norm on a regular Browning action, thus reducing muzzle climb substantially in addition to attenuating recoil, and therefore improving accuracy, recovery time, and controllability. | ||||||

| Disclosed is a firearm configuration for a handgun. The firearm configuration is designed to reduce the recoil forces encountered by a user upon firing the weapon. Recoil forces are reduced by lowering the firearm's center of mass and by aligning a recoiling mass with the user's arm and trigger finger. The various detail of the present disclosure, and the manner in which they interrelate, will be described in greater detail hereinafter. | ||||||

| A recoil-reducing weapon may include a housing and a receiver translatably disposed in the housing. A barrel may have one end fixed to the receiver and be translatable with respect to the housing. A spring stop may be fixed to the barrel forward of the housing and a spring may be disposed between the spring stop and a front of the housing. An operating group with a gear rack may be translatably disposed in the receiver. A longitudinal member may have one end fixed to the operating group. A counter-mass may have a second gear rack and an opening therein for receiving the longitudinal member. A second spring may be disposed around the longitudinal member. One end of the second spring may bear against the operating group and another end of the second spring may bear against the counter-mass. A pinion gear may be rotatably fixed to the receiver and operable to mesh with the gear rack and the second gear rack. | ||||||

| 8 | Safety and bolt assembly system for firearms | US122406 | 1998-07-25 | US5941005A | 1999-08-24 | Vincent Battaglia; William Grehl |
| A safety and bolt assembly system for firearms, particularly for a shotgun. A firing pin is slideable within an opening in the gun's bolt to strike a shell in the gun. The firing pin being movable between a first position in which it is aligned with the opening and capable of sliding movement to strike the shell and a second position in which it is out of alignment with the opening and incapable of sliding movement to strike the shell. The gun safety system includes a spring for urging the firing pin away from the shell and an angled slot for moving and retaining the firing pin away from the shell when the bolt is in the second position. A link is adapted to connect the bolt/slide to a bolt operating system, a pin is secured to one of the bolt/slide or link, and a slot is present in the other of the bolt/slide or link to receive the pin. The slot is angled rearward to prevent movement of the pin from the slot during movement of the bolt/slide in the direction of the link. A leaf spring support member is movable to permit the pin to be removed from the slot while secured to the one of the bolt/slide or link and to permit the bolt/slide to be completely removed from the receiver without removing the operating system from the gun. | ||||||

| Because of a clearance between a barrel supporting member and a barrel, a rotational movement of the barrel is not always constant. Thus, trajectory of a bullet is misaligned. A counterweight 40 is located upper than a barrel 10, and rings 61, 62, which are support portions, are located nearer to the counterweight 40 than a gravity center of the barrel 10. Since the barrel 10 is located lower than the counterweight 40 and engaged with a lower surface side of a gear 30, when a bullet is shot and the barrel 10 is moved backward, a force to rotate the barrel 10 itself clockwise is imparted by a circular surface shape of the gear 30. The barrel 10 receives a force to be rotated clockwise from the gravity center position, the ring 61 and the ring 62, and the barrel 10 is in contact with the inner surface of the barrel supporting member 50. Thus, in spite of the existence of the clearance, the barrel 10 is not displaced in the barrel supporting member 50. | ||||||

| This automatic small arm mechanism provides the locking of the firing members by means of an independent member adapted to engage the intermediate lock member controlled automatically by the inertia block or manually. Thus, the main lock bolt will lock the intermediate lock member when the breech block is in its closed position, whereby the striker return spring may be as strong as desired and necessary since the return movement of the independent percussion member has no incidence whatsoever on the lock bolt position.
