The present invention relates to a pistol accessory. More particularly, the present invention relates to a firing control system with multiple safeties which is installed inside a pistol.
Pistol is an ancient weapon. It was first seen in the sixteenth century AD. In the United States, the pistol is the most common self-defense weapon and is also used in some competitive games. For freedom and safety, most households have at least one pistol in case of emergency.
With hundreds of years of technical improvement, today's pistol has the following advantages: high accuracy, fast reloading speed, strong lethality and easy maintenance. Ordinary people can easily get started after simple use training. However, the loaded pistol is in a dangerous state. If it is not handled properly, such as the pistol falling to the ground or touching it by mistake, it is easy to cause misfire and trigger the bullet. Since the muzzle position of the current pistol is uncertain, the probability of accidentally injuring people around is very high. Therefore, most pistols have an anti-misfire design.
Take GLOCK 43 pistol (the 5th generation product including models 17 and 19 with similar actuators) as an example, it is a very popular product in Europe and America. It has three safeties for unintentional discharge. A first safety for unintentional discharge is trigger safety. It is installed in the trigger in the form of a lever. When the trigger is pulled alone, the trigger safety catches the socket seat to prevent the trigger from moving backwards. When firing the pistol, it is only to press the trigger safety first then pull the trigger. A second safety for unintentional discharge is firing pin safety. The firing pin safety is a short cylinder with a spring inside. When the GLOCK 43 is in the unfired state, the firing pin safety blocks the firing pin to prevent it from hitting the bullet primer. When the trigger is pulled back, the trigger bar pushes the firing pin safety up, and the firing pin passes through the firing pin safety to fire the bullet. The firing pin safety is then reset by the force of the spring, blocking the firing pin again. A third safety for unintentional discharge is falling safety. The falling safety is part of the trigger bar design, located on the safety ramp inside the trigger mechanism housing. The falling safety engages the rear of the firing pin to prevent the firing pin from moving forward. When the trigger is pulled back, the trigger bar lowers the falling safety position and releases the firing pin. After firing, the trigger bar moves up, and the falling safety re-engages the firing pin. In practice, the three safeties for unintentional discharge are all directly or indirectly connected to the trigger bar. Since the pistol will move the trigger bar when it is shaken, it may cause the safeties for unintentional discharge to fail. In addition, when the user shoots the gun, he has to overcome the resistance of the trigger bar pulling the firing pin, so the strength of the finger is strengthened, which is easy to cause shooting deviation.
In order to solve the abovementioned defects in the GLOCK 43 original design, some parts manufacturers have improved the original trigger bar. For example, an Alpha Competition Series for Glock Gen 5 product developed by TIMNEY TRIGGERS is an example. The improvement of the product for GLOCK 43 is to cancel the mechanism of pulling the firing pin by the falling safety but still remain a safety mechanism to block the firing pin ready to fire. At the same time, the stroke of the improved terminal safety design is perpendicular to the direction of travel of the firing pin. The work of pulling the firing pin is handed over to slide. Therefore, when shooting, the force of the user to pull the trigger is smaller than that of the original factory, which reduces the operation resistance and increases the accuracy of aiming. The overall design of the product can perfectly replace the original trigger bar without modifying the pistol. However, many users who have used the GLOCK 43 pistol modified by the Alpha Competition Series for Glock Gen 5 have found that the product is prone to fire due to impact. The reason is that although the end safety is supported by the spring and can protrude to block the firing pin, but if the pistol is impacted, such as falling to the ground, the spring and the end safety will also vibrate accordingly, and the firing pin may go over the end safety and the pistol fires. An easy way to improve this is to increase the stiffness of the spring (make it stiffer). But in this way, it will become more difficult for the user to pull the trigger, and the hidden danger of misfire still exists.
In order to solve the defects of the above-mentioned improved products, let GLOCK 43 and its extended products have both excellent operability and safety, thus the present invention is proposed.
This paragraph extracts and compiles some features of the present invention; other features will be disclosed in the follow-up paragraphs. It is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims.
In order to meet the aforementioned requirements, a firing control system with multiple safeties is disclosed. The firing control system with multiple safeties is used to replace a trigger bar and a trigger spring in a pistol consisting of model GLOCK 17, GLOCK 19 and GLOCK 43 and comprises: a base, installed inside a trigger mechanism housing of the pistol, having a front end and a rear end which is lower than the front end, wherein an arc surface groove is formed in the front end, and the rear end is concave to form a clamping platform; a return spring, an end thereof is placed on the clamping platform; a firing pin releaser, comprising: an arc surface turning portion, rotatably mounted in the arc surface groove; a limit protruding portion, formed on one side of the arc surface turning portion, stopping the arc surface turning portion from rotating toward a forward direction relative to the arc surface groove by contacting a first side plane of the front end; a body portion, extended from and formed on the other side of the arc surface turning portion, wherein a limit side plane and a clamping surface are formed on the bottom of the body portion, the body portion stops the arc surface turning portion from rotating toward a reverse direction relative to the arc surface groove by contacting a second side plane between the front end and the rear end with the limit side plane, and the return spring is clamped by the clamping surface and the clamping platform clamp; and a release portion, protrudingly formed on the top of an end of the body portion, for holding or releasing firing pin handle of a firing pin of the pistol; and a trigger connecting bar, having a connecting portion movably linking to a trigger of the pistol, a linkage portion bent to bypass a magazine of the pistol and connected to the connecting portion, a guiding portion connected to an end of the linkage portion, and a trigger safety portion extended vertically from the guiding portion and movably located above the firing pin releaser, wherein the guiding portion is placed in a connector of the pistol, and when the firing pin of the pistol is ready to fire, the trigger safety portion suppresses the limit protruding portion upon the first side plane, so that the release portion is moved up by rotation of the arc surface turning portion to hold the firing pin handle.
According to the present invention, after the trigger under a status ready to fire is pulled, the trigger connecting bar is linked to move, the guiding portion is pushed by the connector to move down toward a direction below the pistol, driving the trigger safety portion to move toward the direction below the pistol and the direction of the release portion, so that the firing pin releaser rotates relative to the base by the arc surface turning portion rotating relative to the arc surface groove until the limit side plane contacts the second side plane, and the position of the release portion is lowered to release the firing pin handle.
According to the present invention, a guiding plane is formed on the top of the body portion.
According to the present invention, the trigger safety portion the trigger safety portion may further comprise: an extension board, extended vertically from the guiding portion, having a suppressing plane formed below; and a stopping moving board, facing the limit protruding portion and being formed in the middle of the extension board, wherein an angle is formed between the stopping moving board and the extension board. When the firing pin is ready to fire, the end of the stopping moving board suppresses the limit protruding portion upon the first side plane. After the trigger under the status ready to fire is pulled, the suppressing plane of the extension board slides along the guiding plane and the body portion is pushed down to rotate the firing pin releaser relative to the base.
According to the present invention, the connector may comprise a sideways guide plate. The guiding portion forms an arc-shaped area facing the sideways guide plate. After the trigger under the status ready to fire is pulled and the trigger connecting bar is linked to move, the arc-shaped area touches the sideways guide plate and is pushed by the sideways guide plate to move toward the direction below the pistol.
According to the present invention, a firing pin safety switch may be further formed on and protruded from the top of the linkage portion. The top of the firing pin safety switch meets a firing pin safety of the pistol. After the trigger under the status ready to fire is pulled and the trigger connecting bar is linked to move, the firing pin safety switch moves up slightly to turn on the firing pin safety and returns to original position by the elasticity of the firing pin safety switch after shooting.
Preferably, a rotatable angle that the arc surface turning portion is able to rotate relative to the arc surface groove ranges from 6 degrees to 10 degrees.
According to the present invention, the base and the firing pin releaser have substantially parallel two main planes, respectively. When the main planes of the base and the main plane of the firing pin releaser fall on a plane on one side, the other main planes of the base and the firing pin releaser fall on another plane on the other side.
According to the present invention, after the pistol fires, the firing pin handle sits above the trigger safety portion.
According to the present invention, when a slide of the pistol moves backwards, the firing pin is driven to move, causing the firing pin handle to move toward the rear of the release portion after pushing down the release portion. The release portion is pushed to move down to let the firing pin releaser rotate relative to the base by the arc surface turning portion rotating relative to the arc surface groove. The firing pin releaser is rotated back to original position by the return spring, so that the release portion holds the firing pin handle again.
Preferably, the base and the firing pin releaser is made of metal and formed by electrical discharge machining process.
Preferably, the trigger connecting bar is made from metal plate and shaped by stamping process.
The trigger safety portion of the present invention with the design of the limit protruding portion of the firing pin releaser forms a safety mechanism to prevent the pistol from unintentional discharge. It improves the problem that the existing improved products are easy to fire in a ready-to-fire state.
The present invention will now be described more specifically with reference to the following embodiments.

The original trigger bar of GLOCK 43 not only has the function of guiding for firing, but also has the function of pulling the firing pin 5 to move backward to position for firing. However, the firing control system with multiple safety 1 of the present invention does not have this function after replacing the original trigger bar. Instead, the movement of a slide of the pistol is used to drive the firing pin 5. In particular, when a slide of the pistol moves backwards, the firing pin 5 is driven to move, causing the firing pin handle 5a to move toward the rear of the release portion 304 after pushing down the release portion 304, from the position in
