This disclosure relates to handgun components and more particularly to a takedown lever for a handgun, a takedown safety mechanism for a handgun, and a trigger shoe for a firearm trigger
Firearms design involves many non-trivial challenges. Traditionally, semiautomatic handguns have been made with a metal frame that includes the grip portion and a body portion with rails along a top surface. The grip portion defines a magazine well into which a magazine is installed. More recently, some semiautomatic handguns have a polymeric grip module that retains a metallic receiver in an open top of the grip module, where the receiver houses the fire control components and includes rails for the slide. Whether a metal frame or a polymeric grip module with drop-in receiver, a slide mounts to and can reciprocate longitudinally along rails that extend along the top of the frame or receiver. A takedown lever can be moved to a takedown position to remove the slide for cleaning and maintenance.
One aspect of the present disclosure relates to a takedown lever that rotates counterclockwise from a firing position to a takedown position, as viewed looking at the left side of the handgun. This rotation direction is opposite that of existing takedown levers. Advantageously, the takedown lever can be used as a thumb rest when firing the handgun. Since the lever rotates counterclockwise rather than clockwise to the takedown position, the lever is stable for use as a rest with downward pressure applied by the user. Another aspect of the present disclosure relates to a takedown lever assembly that includes a safety block. When the takedown lever is moved to the takedown position, the safety block moves rearwardly so that it protrudes into the magazine well. The safety block may additionally or alternately move against the trigger body to prevent the trigger from pivoting (i.e., from being pulled) when the takedown lever is in the takedown position. A further aspect of the present disclosure relates to a trigger with a trigger assembly that includes a trigger body and trigger shoe.
The features and advantages described herein are not all-inclusive and, in particular, many additional features and advantages will be apparent to one of ordinary skill in the art in view of the drawings, specification, and claims. Moreover, it should be noted that the language used in the specification has been selected principally for readability and instructional purposes and not to limit the scope of the disclosed subject matter.
These and other features of the present embodiments will be better understood by reading the following detailed description, taken together with the Figures herein described. For purposes of clarity, not every component may be labeled in every drawing. Furthermore, as will be appreciated, the figures are not necessarily drawn to scale or intended to limit the present disclosure to the specific configurations shown. In short, the Figures are provided merely to show example structures.
Disclosed is a takedown lever for a semiautomatic handgun. In accordance with one embodiment, the takedown lever rotates counterclockwise from the shooting position to the takedown position as viewed looking at the left side of the handgun. For example, in the takedown position, the lever wing extends upward along the slide from the lever shaft; in the shooting position, the lever extends horizontally and abuts the frame. Accordingly, when the lever is in the shooting position the user may use the takedown lever as a thumb rest. In some embodiments, the takedown lever can be shaped to enhance its use as a thumb rest.
Also disclosed is a takedown safety for a semiautomatic handgun. In one example, a block or lever is displaced rearwardly when the takedown lever is moved to the takedown position. When the mechanism includes a block, for example, a proximal end of the block protrudes into the magazine well and prevents installation of a magazine into the magazine well while the takedown lever is in the takedown position. Similarly, the takedown lever cannot be moved to the takedown position when a magazine is in the magazine well. This safety feature prevents the user from loading the gun while the takedown lever is in the takedown position, such as during cleaning.
In some embodiments, the lever or block abuts or is positioned closely adjacent to part of the trigger body when the takedown lever is in the takedown position. For example, a block moves to the front face of the trigger body above the trigger pin. Accordingly, the trigger cannot rotate and is blocked from being pulled by the user. One such embodiment is particularly useful in a hammer-fired handgun where blocking trigger rotation also prevents disengagement of the sear and therefore prevents release of the hammer. Accordingly, even if the gun contains a round in the chamber, the user cannot pull the trigger while the takedown lever is in the takedown position.
Further disclosed is a trigger assembly that includes a trigger body and a trigger shoe. In one example, the trigger shoe attaches to the trigger body using a snap fit. The removable trigger shoe enables the user to change the trigger shoe as desired for different profile, appearance, or material, and the user may do so without the need for armorer training.
Safety continues to be an important challenge for firearms designers. Handguns can be made with external safety levers that are activated by the user. Handguns can also have one or more internal safeties that prevent discharge when the firearm is dropped, for example.
One non-trivial issue of firearms design and performance pertains to preventing unintended discharge during the takedown and cleaning process. When proper takedown protocol is followed, cleaning and servicing the firearm is a safe event. According to recognized safety protocol, the user first releases the magazine from the magazine well, followed by racking the slide to eject the chambered round (if present), and visually checking the chamber to ensure no ammunition is present. Finally, the user decocks the action or pulls the trigger full cycle to release the spring tension on the striker or hammer. From this condition, the user may proceed to disassemble or “take down” the handgun for cleaning or service
Unfortunately, however, not all gun owners follow safe protocol and the result can be an unintentional discharge during the course of cleaning a handgun. For example, after releasing the magazine, the user may pull the trigger to decock the action without first clearing the chamber. If a round is chambered, pulling the trigger can fire the gun. Also, with the slide removed, some users may attempt to install a magazine into the magazine well, such as to view how the loaded magazine interacts with other components of the action. Again, an unsafe condition and unintentional discharge can result.
In the interest of preventing unintentional discharges when cleaning a handgun, a safety mechanism can prevent the user from unsafe actions when field stripping or cleaning the handgun. For example, one such safety prevents release of the hammer or striker when the slide is removed from the handgun. In another example, a safety prevents removing the slide when the magazine contains a magazine in the magazine well. Despite these advances, a need still exists for new safety mechanisms in handguns.
To address this need and others, the present disclosure relates to a safety mechanism for semiautomatic handguns. One aspect of the disclosure is directed to a takedown lever configured to rotate in a counterclockwise direction from the shooting position to the takedown position as viewed looking at the left side of the gun. Another aspect of the disclosure is directed to a takedown assembly for a hammer-fired handgun. In one example, the takedown lever engages and pivots a block having arms that extend rearwardly along sides of the trigger body. When the takedown lever is moved to the takedown position, the block is shifted rearwardly into contact with or closely adjacent to a front part of the trigger, blocking trigger rotation. At the same time, a proximal end portion of the arm or arms extends into the magazine well a distance sufficient to prevent a magazine from being installed in the magazine well. Similarly, the takedown lever is blocked by a magazine from moving to the takedown position if a magazine is present in the magazine well. The takedown assembly according to the present disclosure can prevent an unsafe condition during takedown by requiring the user to remove the magazine prior to moving the takedown actuation lever to the takedown position. The assembly also can block rotation of the trigger when the takedown actuation lever is in the takedown position. One additional aspect of the present disclosure relates to a trigger that includes a trigger body and a trigger shoe that can be removably attached to the trigger body, such as with a snap fit. Various aspects of the present disclosure can be utilized individually or in combination in a handgun. Numerous configurations and variations will be apparent in light of this disclosure.
As will be appreciated in light of this disclosure, and in accordance with some embodiments, a takedown assembly and its components can be used with a semiautomatic handgun, particularly one that is hammer-fired. In accordance with some example embodiments, a takedown assembly can be part of a semiautomatic handgun chambered in .22 LR, .380 Auto, 9 mm Luger, .357 SIG, 10 mm Auto, .40 S&W, .45 ACP ammunition, or any other suitable ammunition. As will further be appreciated, a removable trigger shoe in accordance with embodiments of the present disclosure can be used in handguns and long guns alike. Other suitable host firearms will be apparent in light of this disclosure.
As used herein, the term “frame” refers to the serialized component of a handgun that houses components of the fire control assembly. In metal handguns, for example, the frame may include the grip portion, trigger guard, and a portion of the frame that extends along the bottom of the barrel. In other handguns having a polymeric grip module, for example, the frame refers to the serialized metal component that can be secured into the open top portion of the grip module and along which the slide reciprocates.
While generally referred to herein as a takedown assembly for consistency and ease of understanding the present disclosure, the disclosed takedown assembly and its components are not limited to that specific terminology and alternatively can be referred to using other terms. For example, the takedown lever alternately can be referred to as a takedown actuation lever, a takedown tab, or other terms. In another example, the safety bar can alternately be referred to as a takedown safety lever, a takedown safety, a safety linkage, or other terms. As will be further appreciated, the particular configuration of a takedown assembly configured as described herein may be varied, for example, depending on whether the handgun is hammer-fired or striker-fired. Numerous configurations and embodiments will be apparent in light of this disclosure.
The takedown lever assembly 40 includes the takedown actuation lever 50 and a safety block 70. The trigger assembly 23 includes the trigger 24, a trigger pin 25, and a trigger spring 28 (not visible; shown in
As can be seen in
The trigger 24 can rotate between a resting position and a pulled position about a trigger pin 25 extending laterally through the trigger body 27 and safety block 70. A trigger shoe 26 attaches to a front, lower portion of the trigger body 27 and is positioned for manipulation by the user.
The cam 54 has first and second portions that protrude radially away from the lever shaft 52. The first portion 54a of the cam 54, which has a first diameter, contacts a front of the safety block 70. The safety block 70 is firmly blocked by the cam 54 from moving forward and provides a solid stop for the trigger spring 28. The second portion 54b of the cam 54 has a second diameter that is greater than the first diameter.
As discussed above with reference to
The takedown actuation lever 50 can be part of a takedown lever assembly 40. When rotated to the takedown position, a cam 54 on the lever shaft 52 is configured to move a safety block 70 rearwardly. In doing so, part of the safety block 70 extends into the magazine well 16 to prevent the user from installing and seating a magazine into the gun. Similarly, when a magazine is present in the magazine well 16, the user cannot rotate the takedown actuation lever 50 to the takedown position due to the safety block contacting the magazine. Also, rotating the takedown actuation lever 50 to the takedown position moves the safety block 70 into contact with the trigger body 27, blocking the trigger 24 from rotating about the trigger pin 25. In the firing position, a body 57 of the takedown actuation lever 50 abuts the receiver 20, providing a hard stop that prevents further rotation of the takedown actuation lever 50 and enables the lever wing 56 to be used as a thumb rest when firing the handgun.
Embodiments of the takedown lever assembly 40 are discussed above in the context of a takedown actuation lever 50 that rotates counterclockwise about 90° from the firing position to the takedown position. For example, the lever wing rotates from a horizontal position where it extends rearward from the lever shaft to a generally vertical position where it extends upward from the lever shaft. It is contemplated within the scope of this disclosure that the takedown actuation lever can rotate in the opposite direction. The takedown lever assembly 40 is also discussed above with reference to a safety block 70 that has a front portion extending laterally between and connecting arms 71, 73 that extending rearwardly along opposite sides of the trigger body 27. It is contemplated within the scope of the present disclosure that the safety block 70 could have the shape of a bar or lever, along with any necessary tabs or protrusions, as will be appreciated. Numerous variations and embodiment will be apparent in light of the present disclosure.
As will be appreciated in light of this disclosure, embodiments of takedown lever assembly 40 described herein are not limited to use with hammer-fired handguns and may be utilized with striker-fired handguns and other host firearms. In addition, embodiments of a trigger shoe, as variously disclosed herein, can be used with handguns and long guns, including pistols, rifles, and shotguns.
Components of takedown assembly may be constructed from any suitable materials as will be apparent in light of this disclosure. For example, some embodiments of takedown lever, safety block, and trigger shoe can be constructed from steel, polymers, composites, aluminum, or other materials. More generally, components of takedown assembly and trigger shoe can be constructed from any suitable material which is compliant, for example, with United States Defense Standard MIL-W-13855 (Weapons: Small Arms and Aircraft Armament Subsystems, General Specification For).
Referring now to
The trigger shoe 104 attaches removably over the lower portion 106 of the trigger body 102. The trigger shoe 104 can be installed over the front of the trigger body 102 and secured using a snap fit. For example, the trigger shoe 104 includes tabs that overlap a rear edge of the trigger body 102 when the trigger shoe 104 is installed. The trigger shoe 104 includes a user surface 116 and shoe side panels 118 extending rearward from the user surface 116. The user surface 116 can be flat or arcuate and is configured for the user to manipulate the trigger.
To install the trigger shoe 104 on the trigger body 102, the shoe side panels 118 can be spread apart slightly to slide the catches 130 over the side panels 120 of the trigger body 102. After moving the trigger shoe 104 is moved rearward onto the trigger body 102 so that the catches 130 pass the rear face 124, the resilient force of the trigger shoe 104 returns the shoe side portions 118 to their previous shape with the catches overlapping the rear face 124 of the trigger body 102 (e.g., a snap fit).
