摘要： Applicant has disclosed an improved trigger assembly for firearms, and a related method, to avoid premature firing after an unintentional trigger rotation, especially where light trigger pulls have previously been set. In the preferred embodiment, Applicant's trigger assembly has two triggers: a slotted primary trigger and a secondary trigger which can pivot into the slot. During an intentional trigger pull, the shooter's finger initially pushes against the secondary trigger until it pivots and nestles within the primary trigger's slot. Continued pulling on both the secondary and primary triggers causes a hammer to rotate off a sear, thereby allowing the firearm to discharge. In an unintentional trigger rotation, where the secondary trigger is not pulled back enough to nestle within the primary trigger's slot: an upper portion of the secondary trigger (unseen within the housing) constrains a protrusion on a spring-biased mainspring guide. This blocks movement of the mainspring guide and prevents the hammer from rotating sufficiently for discharge.
摘要翻译： 申请人已经公开了用于火器的改进的触发器组件以及相关方法，以避免在无意的触发器旋转之后的过早点火，特别是在光触发器拉动已经被设置的情况下。 在优选实施例中，申请人的触发器组件具有两个触发器：开槽主触发器和可以枢转到插槽中的辅助触发器。 在有意触发拉动期间，射手的手指最初推动次级扳机，直到其枢转并且安置在主触发器的槽内。 继续拉动次要和主要触发器都会使锤子从肘部旋转，从而允许枪支放电。 在无意的触发器旋转中，辅助触发器不被拉回到主触发器的插槽内：辅助触发器的上部（在壳体内看不见）限制弹簧偏置的发条引导件上的突起。 这阻挡了发条引导件的移动，并防止锤子充分旋转以进行排放。

摘要： The hammer of a gun has a channel in its front face, making direct contact between the hammer and the gun's firing pin impossible. The tip of a transfer bar retained within the channel moves to fill the channel and thus permit firing of the gun, only when the trigger is pulled. This construction avoids certain types of accidental discharge.

摘要： A firearm having a frame, a barrel, a trigger which is pivotally connected to the frame, a hammer which is pivotally connected to the frame, and a hammer block which is integral with the trigger and extends upwardly from the trigger to prevent the hammer from reaching it forward firing position when the trigger is in its forward position, and allowing the hammer to reach its forward firing position when the trigger is in its rearward position. The trigger is biased to its forward position and the hammer is also biased to its forward firing position.

摘要： A four-barrelled pistol is disclosed which comprises a hammer having a rotating, click-action head for successively acting on firing pins corresponding to the four barrels. Particularly, a tripping mechanism is disclosed which controls the hammer of the pistol to allow either a single-action or double action operation. The pistol includes a mechanism for blocking and keeping the hammer in a cocked position when the trigger is at rest and for unblocking it when the trigger has been displaced, and mechanism for displacing the hammer into the cocked position and disengaging it immediately thereafter as a result of the displacement of the trigger.

摘要： A trigger assembly group for use in firearms is disclosed. The trigger assembly group comprises a primary trigger connected to a secondary trigger that is arranged and configured to reduce the incidence of accidental discharge caused by inadvertently rearwardly actuating a primary trigger. The disclosed primary trigger and secondary trigger are arranged and configured for linear movement within a housing. The secondary trigger includes locking wing members that move from engagement with upper locking housing grooves to lower housing grooves. The disclosed trigger assembly group further includes a trigger shoe connected to the primary trigger, wherein the trigger shoe comprises a channel formed therein. A lower portion of the secondary trigger is configured to move from a forwardmost position, extending outwardly from the front face of the trigger shoe, to a rearmost position in which the lower portion of the secondary trigger recedes into the channel of the trigger shoe.

摘要： A gun lock of a firearm having two hammers movably disposed on a lock support, a trigger bar for each hammer for holding or releasing the hammers, a trigger, and a disconnector for the trigger, by which disconnector the trigger bars can be moved by the trigger from a holding position into a release position. The disconnector can be moved by an inertial mass between a triggering position, in which the trigger is connected to one of the two trigger bars, and a disconnect position, in which the connection between the trigger and the trigger bars is interrupted. The inertial mass is a pendulum mass swiveling about a transverse axis between a starting position and a safe position, by which the disconnector, upon the release of a first hammer, can be swiveled in a direction opposite to the direction of the pendulum mass into the disconnect position.

摘要： A safety mechanism for use with a firearm having a hammer wherein the hammer has an elongated, vertically extending recess formed therein, a transfer bar traveling within that elongated recess between an extended position and a retracted position. When the transfer bar is in the extended position, the bar is interposed between the hammer and the firing pin allowing discharge of a cartridge within the chamber. When the transfer bar is in the retracted position, a portion of the recess is exposed. The exposed recess is larger than the portion of the firing pin which protrudes from the receiver. Thus, inadvertent firing is prevented as the hammer cannot contact the firing pin. A transfer bar carrier pin located on the hand assembly initially cooperates with the trigger cam and the transfer bar to elevate the bar into the extended position. The weight of the safety mechanism is, therefore, not borne by the trigger, when the hammer is in the full cock position, resulting in a lighter and more accurate trigger pull. After the trigger has been fully actuated, the transfer bar carrier drops with the hand mechanism and a cam on the trigger maintains the transfer bar in the extended position. The trigger must remain in the fully actuated position until the hammer and transfer bar impact the firing pin. Premature release of the trigger will allow the transfer bar to drop and the firing pin will merely enter the recess in the hammer without contacting the hammer.
摘要翻译： 一种用于具有锤的枪支的安全机构，其中所述锤具有形成在其中的细长的垂直延伸的凹部，转移杆在延伸位置和缩回位置之间的所述细长凹槽内移动。 当传送杆处于延伸位置时，杆被插入在锤和击发销之间，允许在腔室内排出墨盒。 当传送杆处于缩回位置时，凹部的一部分露出。 暴露的凹部大于从接收器突出的撞针的部分。 因此，当锤不能接触撞针时，防止意外击打。 位于手组件上的传送杆承载销最初与触发器凸轮和传送杆配合以将杆升高到伸出位置。 因此，当锤子处于完全旋塞位置时，安全机构的重量不受触发器承受，导致更轻和更准确的触发器拉动。 在触发器完全启动之后，传送杆托架用手动机构下降，并且扳机上的凸轮将转移杆保持在伸出位置。 触发器必须保持在完全启动的位置，直到锤和传送杆撞击撞针。 触发器的过早释放将允许传送杆下降，并且撞针仅仅进入锤中的凹部而不接触锤。

摘要： The sear is rotatably supported in the frame of the firearm to rotate around an axis of rotation. The hammer is pivotally mounted in the frame to pivot around a pivot axis. The hammer includes a striking surface. The sear includes a blocking surface which cooperates with a resting surface of the hammer. The position of the blocking surface of the sear which is determined by its axis of rotation, the position of the striking surface of the hammer, which is determined by the location of the pivot axis of the hammer, and the position of the rear end of the firing pin are selected in such a manner that when the hammer is in its decocked position, in which position the resting surface contacts the blocking surface, the striking surface of the hammer is at a distance from the rear end of the firing pin. Accordingly, the hammer does not contact in its decocked state the firing pin such that eg upon a dropping of the firearm a shot may inadvertently be fired. Furthermore, because the hammer is in its decocked position already remote from the rear end of the firing pin, a shorter and smoother path of pulling the trigger is needed when firing the firearm, which allows an improved hitting of a target. The hammer is automatically decocked after each shot.
摘要翻译： 该火腿被可旋转地支撑在枪支的框架中以围绕旋转轴线旋转。 锤子枢转地安装在框架中以围绕枢转轴线枢转。 锤子包括一个醒目的表面。 烙铁包括与锤的搁置表面配合的阻挡表面。 由其旋转轴线确定的火花塞的阻挡表面的位置，由锤的枢转轴线的位置确定的锤的撞击表面的位置以及后端的位置 击打销的选择方式是当锤处于其解锁位置时，搁置表面接触阻挡表面的位置，锤的击打表面距离撞针的后端一定距离。 因此，锤子在其解锁状态下不接触击发销，使得例如在枪支的下落时可能不小心被点燃。 此外，由于锤子处于已经远离击发销的后端的折叠位置，所以当点火枪支时，需要更短且更平滑的拉动扳机的路径，这允许改进的目标击球。 每次拍摄后，锤子都会自动分解。
