Abstract
Description
Technical Field
[0001] The present invention relates generally to firearms, and in particular to a pistol to rifle conversion kit that converts a pistol into a rifle having a grip, trigger, and magazine positioned as in an assault rifle. Background Art
[0002] Pistol to carbine or rifle conversion kits are well known. A pistol is mounted in an assembly with a stock, and the assembly essentially converts the pistol into a carbine or rifle that can be fired with the stock resting on the shooter's shoulder. The assembly acts as a pistol stabilizer. (The terms pistol and handgun are used interchangeably, and the terms carbine and rifle are used interchangeably)
[0003] In all known pistol to rifle conversion kits, the pistol is held in a rifle-like assembly. The shooter loads a magazine into the pistol and pulls the trigger of the pistol in order to fire the pistol. Summary of the invention
[0004] The present invention seeks to provide a novel pistol to rifle conversion kit that converts a pistol into a rifle and places the components into an assault rifle as described below.
[0005] In all known pistol to rifle conversion kits, the trigger (the trigger that the shooter's finger directly contacts) is in front of the magazine well (front is defined as the direction toward the part of the weapon that fires bullets; rear is defined as the direction opposite to the front and toward the butt of the weapon). This is because in the conversion kits of the prior art, the shooter's finger directly contacts the pistol trigger, and the magazine well is in the pistol grip. In contrast to the prior art, in the present invention, the conversion kit uses an auxiliary trigger that is located behind and coupled to the pistol trigger. This results in the rifle having a magazine well (the magazine of the pistol installed in the rifle conversion kit) adjacent to the auxiliary trigger (the auxiliary trigger is the trigger that the shooter's finger directly contacts) and in front of the auxiliary trigger, and the auxiliary trigger is adjacent to the handle of the rifle and in front of the handle. Therefore, the conversion kit of the present invention uniquely has the handle, trigger, and magazine well adjacent to each other on the rifle lower receiver, in order from back to front, as positioned in an assault rifle, such as an M-16, AR-15, and AK-47. (The lower receiver of an assault rifle is the part that houses the grip (handle), trigger guard, and magazine well.)
[0006] It should be noted that known corner shot weapon systems also have an auxiliary trigger coupled to the firearm trigger. However, the present invention has a different structure. In the present invention, the magazine well is adjacent to the auxiliary trigger; in the corner shot, the magazine well is not adjacent to the auxiliary trigger, but is on the actual weapon on a pivoting mount (not the rifle receiver) away from (not adjacent to) the auxiliary trigger. The corner shot (or prior art periscope rifle system) does not have adjacent, rear-to-front sequential handle, trigger, and magazine well on the rifle lower receiver, as positioned in an assault rifle.
[0007] Thus, the conversion kit of the present invention uniquely gives the shooter the exact same feel of shooting and changing magazines as assault rifles such as the M-16, AR-15, and AK-47.
[0008] Therefore, according to a non-limiting embodiment of the present invention, a pistol to rifle conversion kit is provided, which pistol to rifle conversion kit includes: a rifle body, the rifle body includes a lower receiver, the lower receiver includes a grip mounting portion, the grip mounting portion is adjacent to the trigger guard rearwardly, the trigger guard is adjacent to the magazine well receiving portion rearwardly, the rifle body is straight and does not pivot from the rear stock mounting portion to the front bullet firing portion; and an auxiliary trigger, which is slidably mounted in the rifle body and includes a slender member and a front trigger interface member and a trigger member, the front trigger interface member extends from the front of the slender member and is configured to engage with the trigger of the pistol installed in the rifle body, and the trigger member extends from the slender member to directly contact the shooter's finger.
[0009] The fore-and-aft sliding movement of the auxiliary trigger may be guided by one or more lugs received in one or more elongated holes formed in the elongated member.
[0010] The auxiliary trigger may be spring loaded by a biasing device.
[0011] A trigger safety may be provided to prevent or allow the trigger member to be pulled.
[0012] The rifle body may include two halves that pivot together about a pivot pin received in holes in the halves and one or more fasteners that secure the halves to each other.
[0013] The rifle body may include a magazine escapement. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Reference now Figure 1 , which shows a loading handle 10 for coupling to a slide 12 of a pistol 14 having a trigger 13 and a grip (handle) 15 according to a non-limiting embodiment of the present invention.
[0023] The loading handle 10 may include an upper portion 16 with a side grip 18. The upper portion 16 may be secured to a lower portion 24 via fasteners 20 and 22, wherein the upper portion 16 is above the slide 12 and the lower portion 24 is below the slide 12. In this way, the completed assembly of the loading handle 10 is secured to the slide 12.
[0024] It is important to note that this is just one example of coupling the loading handle 10 to the slide 12 of the pistol 14. Alternatively, the loading handle 10 may be slidably mounted to a rifle body (described below) and when the pistol 14 is coupled to the rifle body, the loading handle is connected to the slide 12 by, for example, but not limited to, a snap fit.
[0025] Now refer to Figure 2A , which shows the pistol 14 to be installed in a portion of the rifle body 26 of the pistol to rifle conversion kit. The portion shown is one half 26R of the rifle body 26, and the other half 26L is in Figure 3 and FIG. 4A to FIG. 4D Shown in.
[0026] The rifle body 26 may include a lower receiver 28 including a grip (handle) mounting portion 30 that is rearwardly adjacent to a trigger guard 32 that is rearwardly adjacent to a magazine well receiving portion 34. As is known in the art, a grip (handle) 36 (see Figure 4A ) can be fastened to the handle (grip) mounting portion 30 using fasteners (not shown).
[0027] The rifle body 26 can be straight and not pivoted from the rear stock mounting portion 38 to the front bullet-firing portion 40. The stock 42 can be attached, for example, by threading or by means of fasteners, as is known in the art (see Figure 5A and Figure 5B ) is fixed to the rear stock mounting portion 38.
[0028] The rifle body 26 may include at least one accessory rail 44 , such as a Picatinny rail, which may extend from the rear stock mounting portion 38 to the front bullet firing portion 40 over most or all of the length of the rifle body 26 .
[0029] The auxiliary trigger 46 can be slidably mounted in the rifle body 26. Figure 3 As shown, the auxiliary trigger 46 may include an elongated member 48 and a front trigger interface member 50 extending laterally from the front of the elongated member 48. The forward and backward sliding movement of the auxiliary trigger 46 may be guided by one or more pins, screws or lugs 52 (fixed to one or more protrusions 53 of the rifle body 26), which are received in one or more elongated holes 54 formed in the elongated member 48. The trigger member 56 extends from the elongated member 48 that the shooter's fingers directly contact. Therefore, when the shooter pulls the trigger member 56, the front trigger interface member 50 pulls the trigger 13 ( Figure 2B and Figure 2C ) to fire the pistol. The auxiliary trigger 46 can be spring loaded by the biasing device 58.
[0030] A trigger safety 60 may be provided, which may be coupled to the cam 62, for example, by a circlip 64. The trigger safety 60 is similar to the safety of an assault rifle, and rotation of the trigger safety 60 prevents or allows the trigger member 56 to be pulled.
[0031] The two halves 26R and 26L of the rifle body 26 can pivot together about a pivot pin 66 received in holes 67 and 68 in the halves 26R and 26L, respectively. The halves 26R and 26L can include one or more fasteners or hooks 69 that secure the two halves to each other. In a non-limiting embodiment, there are only three hooks 69 for quick assembly.
[0032] The rifle body 26 may include a magazine catch 70 that aligns with the magazine catch of the pistol when the pistol is installed in the rifle body so that depressing the magazine catch 70 releases the magazine from the pistol.
[0033] Now refer to Figure 4A , Figure 4B , Figure 4C and Figure 4D , which illustrates the installation of a pistol into a rifle body of a pistol to rifle conversion kit according to a non-limiting embodiment of the present invention.
[0034] Figure 4A The fastener 69 is shown with the rifle body 26 open. Figure 4B The rifle body 26 is shown opened (with the left half 26L pivoted away from the right half 26R) and the pistol 14 to be installed in the rifle body. Figure 4C The pistol 14 is shown installed in the rifle body 26 and the left rifle half 26L is about to be closed. Figure 4D The pistol is shown mounted and enclosed in a rifle body 26.
[0035] Figure 5A and Figure 5B A complete pistol to rifle conversion kit 100 is shown according to a non-limiting embodiment of the present invention. The stock 42 has been secured to the assembly and the magazine 72 has been inserted into the magazine well of the pistol. The completed pistol to rifle conversion kit 100 looks like an assault rifle and shoots like an assault rifle.
