The present disclosure relates to reliefs in the frames of firearms.
Hand pistols taught by U.S. Pat. No. 984,519, or some variation thereof, (each a “1911”) have been in production for over one-hundred years. During that time, the 1911 has developed a loyal following for a variety of reasons. Unfortunately, certain features of the 1911 are not optimized.
A 1911 includes a frame, a hammer pivotally coupled to an upper portion of the frame, a slide slidably coupled to the frame and forming a void therebetween (the “barrel void”), and a barrel positioned at least partially within the barrel void. The barrel is coupled to the frame and operably linked to the slide such that movement of the slide causes the barrel to move as well. In particular, the barrel rocks backward towards a loading position as the slide moves backwards towards a cocking position. After cocking and loading the firearm, the slide and the barrel move simultaneously back to their respective firing positions. Unfortunately, the 1911 is at least somewhat susceptible to debris migrating into internal areas of the firearm, such as the barrel void. Once inside the firearm, the debris can collect in one or more working joints of the firearm (and/or can collect in one or more other areas) in such a way as to cause unnecessary wear or other damage. Accordingly, it would be beneficial to have a 1911-style firearm that includes provisions for mitigating risk associated with debris.
Of particular concern is debris migrating into the barrel of the 1911, such as through the breech of the barrel during a loading operation for the firearm. Accordingly, it would be beneficial to have a 1911-style firearm that includes provisions for directing debris away from the breech of the barrel.
In some aspects, the techniques described herein relate to a firearm including: a slide assembly; a barrel; a frame configured mate with the slide assembly, wherein the frame and the slide assembly can house the barrel, wherein the frame includes an inner surface; a relief in the inner surface of the frame wherein the relief is coaxially situated on the inner surface of the frame; and a barrel lug configured to removably attach the barrel to the frame, wherein the barrel lug further includes a first flute and a second flute.
In some aspects, the techniques described herein relate to a firearm including: a slide assembly; a barrel; a frame configured mate with the slide assembly, wherein the frame and the slide assembly can house the barrel, wherein the frame includes an inner surface; and a relief in the inner surface of the frame wherein the relief is coaxially situated on the inner surface of the frame.
In some aspects, the techniques described herein relate to a firearm frame including: an inner surface; and a relief in the inner surface of the frame wherein the relief is coaxially situated on the inner surface of the frame.
Further features of the disclosed systems and methods, and the advantages offered thereby, are explained in greater detail hereinafter with reference to specific example embodiments illustrated in the accompanying drawings.
In order to facilitate a fuller understanding of the present invention, reference is now made to the attached drawings. The drawings should not be construed as limiting the present invention, but are intended only to illustrate different aspects and embodiments of the invention.
Exemplary embodiments of the invention will now be described in order to illustrate various features of the invention. The embodiments described herein are not intended to be limiting as to the scope of the invention, but rather are intended to provide examples of the components, use, and operation of the invention.
Furthermore, the described features, advantages, and characteristics of the embodiments may be combined in any suitable manner. One skilled in the relevant art will recognize that the embodiments may be practiced without one or more of the specific features or advantages of an embodiment. In other instances, additional features and advantages may be recognized in certain embodiments that may not be present in all embodiments.
The present invention comprises a modified 1911 hand pistol (the “2311”). The 2311 is similar enough to a 1911 to satisfy most loyalists, while resolving certain deficiencies associated with the 1911. Like the 1911, the 2311 includes a barrel void positioned between a frame and a slide. Both firearms also include a barrel positioned at least partially within the barrel void. Unlike the 1911, an inner surface of the frame of the 2311 defines a relief in communication with the barrel void (or forming part of the barrel void, as the case may be), the relief being configured to capture debris, thereby mitigating risk associated with the debris. Furthermore, some embodiments of the 2311 include provisions for directing debris away from a breech of the barrel.
The debris management elements provide several benefits over conventional handguns. For example, the debris management elements can enhance reliability of the handgun. Debris, such as dirt, dust, or small particles, can disrupt the smooth functioning of the firearm's moving parts. By reducing the risk of debris entering the internal areas, particularly the barrel void, the firearm's reliability and overall performance can be improved. Unwanted debris can cause malfunctions, misfeeds, or other operational issues, leading to potential failures or delays in critical situations. Furthermore, the debris management system can reduce the need to maintain the handgun and in turn improve durability. Debris accumulation in working joints or other areas of the firearm can contribute to increased wear and tear. Over time, this can lead to mechanical problems and a decrease in the firearm's lifespan. By designing the 1911-style firearm with better debris mitigation, the need for frequent cleaning, maintenance, and repairs can be reduced, ensuring long-term durability and minimizing downtime. Furthermore, these elements will improve consistency and accuracy of the handgun in use. Any foreign material present in the barrel or other critical areas of the firearm can affect the accuracy and consistency of the shots. Even small debris particles can disrupt the trajectory of the bullet or affect the timing of the firearm's cycling mechanism. By minimizing debris intrusion, the firearm can maintain its intended precision and consistency, crucial for accurate shooting. Finally, these debris management elements will improve safety and functionality. A clean and well-maintained firearm is essential for safe operation. Debris inside the firearm can potentially interfere with safety mechanisms or cause unintended behavior, posing a safety risk to the shooter and those in proximity. Improving debris mitigation in the 1911-style firearm ensures that it operates as intended, reducing the likelihood of accidental discharges or other safety-related issues. In summary, enhancing the debris mitigating elements of the 1911-style firearm leads to improved reliability, reduced maintenance requirements, increased durability, consistent accuracy, and enhanced safety. These benefits collectively contribute to a more effective and reliable firearm for the user.
