The invention is related to an inner case provided between the gun body/frame and the bolt/slide of hand guns and in which various mechanisms are mounted.
Guns can be manufactured from steel, aluminum, polymer, or composite materials. In guns, the frame set is located in the body/frame of the gun. Gun bodies/frames can be manufactured from steel, aluminum, or polymers. The bodies/frames made of steel and aluminum can show sufficient strength for the frame set and the bolt set to work in harmony. Gun bodies/frames made of polymer cannot show sufficient strength to fulfill this task. Therefore, polymer case bodies/frames are supported by a component made from steel, called casing.
In the document with publication number U.S. Pat. No. 9,310,160B1, a metal polymer hybrid gun is disclosed. Here, the term hybrid refers to a polymeric gun body/frame and a metallic case placed inside the said gun body/frame. Holes for mounting various mechanisms of the gun are provided on the metallic body/frame.
In the production of steel parts, called the case, which is used to support polymer bodies/frames, there are long-term and narrow tolerance machining processes, and therefore the cost is high. In addition, meeting tolerances and performing the verification of the finished product are also challenging. In the metal injection molding (MIM) method, which is another method of producing cases from steel material, there are problems such as getting the casting cavities or tolerances right.
As a result, all the above-mentioned problems have made it necessary to make an innovation in the related technical field.
The present invention aims to eliminate the above-mentioned problems and to make a technical innovation in the related field.

In this detailed description, an inner case for the hand gun of the invention is only explained with examples that will not create any limiting effect so that the subject can be better understood.
The subject of the invention is related to an inner case provided between the gun body body/frame and the bolt/slide (not shown in the figures) of hand guns, in which various mechanisms are mounted.
Referring to
The said hand gun (T) can only have a pinned, hammer, or hammer-pinned firing mechanism. If the hammer and hammer-pinned systems are selected, accordingly they contain at least one hammer (not shown in the figures). The said hammer detonates the ammunition capsule directly or indirectly (via a pin) with the drive provided by the trigger (not shown in the figures).
The inner case (1) of the hand gun (T) consists of three basic parts, namely the rear support (10) and the front support (20), and the body (30). The rear support (10) and front support (20) and the body (30) mentioned here are shown separately for a better understanding of the invention, and in the invention, the rear and front supports (10, 20) are provided embedded in the body (30) as in
The inner case is placed in the case housing (KY) provided on the gun body/frame and is then fixed in the case housing (KY) by means of the connecting pins (40) passing through the holes provided on the same and the gun body/frame (50). The said connection pins (40) can be provided as the case connection pin (41) that connects the case with the gun body/frame (50) and/or the barrel connection pin (42) that fixes the barrel to the case and the gun body/frame (50).
With reference to
The front and rear bolt/slide bolts/slides (11, 21) are the part where the movable upper bolt/slide (not shown in the figures) part of the hand gun is placed. The front and rear bolts/slides (11, 21) form the rear and front channels (111, 211), respectively, and the bolt/slide can move back and forth linearly on the channel axis by being seated in these channels. Here, the channels can be formed directly on the front and rear bolt/slide rails (11, 21).
Many openings and holes can be found in the inner case (1) for mounting the firing mechanisms of the hand gun (T). As the whole mechanism can be mounted on the case (1), some mechanical elements can also be mounted on the gun body/frame (50). Some of the mounting openings to be described here may be absent in some embodiments of the case (1). Mounting openings that are not present in such embodiments may be provided on the gun body/frame (50) or may not be present on the hand gun (T) if not needed.
There is a barrel opening (31) on the said body (30) where the barrel connection pin (42) can be placed in order to connect the barrel to the case (1). In addition, there is a case body/frame opening (50) that allows the connection pin (41) of the case to pass through and fix the case (1) to the gun body/frame (50). In addition, on the body (30), the case trigger connection opening (33), the case hammer connection opening, and the case latch connection opening (34) for connecting the trigger, hammer, and latch to the case (1), respectively, and a hammer spring opening for the connection of the hammer spring (36) has been formed. The distribution of the said openings in the figures only shows an embodiment of the invention and can be provided completely differently from the configuration of the hand gun (T).
With reference to
The said rear support (10) and front support (20) are two discrete metal parts that are not connected, placed at points that will increase the strength specifically.
The front support (30), on the other hand, comprises two opposing surfaces parallel to each other and an extension connecting these two surfaces, and the said extension remains on the part of the body (30) facing the barrel side.
In addition, there is a base opening (25) between the two surfaces mentioned, where another surface is provided. The base opening (25) is provided by opening a certain area on the surface, and in order to open the area, the part is bent into the gun body/frame (50) to form a support extension (26). The said abutment extension (26) sits on a support surface (54) formed on the case housing (KY) and provides a support point for the case (1). The said abutment extension (26) extends through the case base opening (37) provided on the body (30).
The said rear support (10) and front support (10) contain mounting openings as with the body (30). If the mounting openings provided on the body (30) are provided in the parts where the rear or front support (10, 20) is located, there may be mounting openings corresponding to the said mounting openings on the surface of the rear or front support (10, 20) concentrically. In addition, the positions of the openings on the rear and front supports (10, 20) shown in the figures are the points where the case (1) has the most difficulty in terms of endurance, therefore, the relevant metal rear and front supports (10, 20) are placed at these points.
A latch connection opening (12) is provided on the rear support (10) so that the latch can pivotally connect via a pin. In order to ensure harmony between the mounting openings mentioned above, the latch connection opening (12) is provided concentrically with the case latch connection opening (35), and the pin connecting the latch passes through both the latch connection opening (12) and the case latch connection opening (35).
A hammer connection opening (13) is provided on the rear support (10) so that the hammer can be rotated through a pin. In order to ensure the harmony between the above-mentioned mounting openings, the hammer connection opening (13) is provided concentrically with the case hammer connection opening (34) and the pin connecting the hammer passes both through the hammer connection opening (13) and the case hammer connection opening (34).
A barrel lock opening (22) is provided on the front support (20) so that the barrel can be securely connected to the case (1) via the barrel connection pin (41). In order to ensure harmony between the above-mentioned mounting openings, the barrel lock opening (22) is provided concentrically with the case barrel connection opening (31) and the pin connecting the barrel passes through both the barrel lock opening (13) and the case barrel connection opening (31).
A case connection opening (23) is provided on the front support (20) so that the case (1) can be securely connected to the gun body/frame (50) via the case connection pin (41). In order to ensure harmony between the above-mentioned mounting openings, the case connection opening (23) is provided concentrically with the case body connection opening (32) and the pin connecting the case (1) passes through both the case connection opening (23) and the case body connection opening (32).

In order to ensure harmony between the mounting openings mentioned above, the trigger connection opening (24) is provided concentrically with the case trigger connection opening (33) and the pin connecting the trigger passes through both the trigger connection opening (24) and the case trigger connection opening (33).
The case (1) of the invention is preferably produced in such a way that its tolerance values are based on the polymer injection method, which gives much more stable results in terms of tolerance in mass production.
First, the rear and front support pieces (10, 20) suitable for any of the above-described embodiments are produced by the sheet molding process and then preferably subjected to the finishing process, preferably using CNC benches. Since the entire case was dependent on machining in the prior art, although this process is not eliminated, the area to be applied has been narrowed, making the process much easier.
Then, the rear and front support (10, 20) parts obtained are placed in the mold that will provide the body (30), and then the heated polymer molds are pressed. Here, the molds are configured so that the polymer does not reach the parts where the rear and front bolt/slide guides (11, 21) are located. The resulting case (1) is then removed from the mold. Here, except for the rear and front bolt/slide guides (11, 21), all the rear and front supports (10, 20) are embedded in the polymer body (30). The said mold is also arranged to form a surface under the rear and front bolt/slide guides (11, 21) to form the rear and front channels (111, 211).
The protection scope of the invention is given in the attached claims, and it cannot be limited to what has been described as an example in this detailed description under any circumstances. It is understood that a person with the skill in the related technique can put forth similar embodiments in the light of what has been described above, without departing from the main theme of the invention.
