Vynález se týká zadtžísvacího) machanísr· mu pro vyjímatelný zásobnífe autamaíídké; pistole, jejíž demontáž se provádí po vychýlení lučíku ze střelecká poibhy zbraná.BACKGROUND OF THE INVENTION The present invention is directed to a mechanical recovery mechanism for a removable storage tank. pistol, whose dismantling is carried out after deflection of the trigger guard from the shooting poibhy weapons.

Známá provedeníi zadržovacích! maiftani®·· mů jsou konstruována, bud. jako, jednostranná, tzn., že mohou být ovládaná z jedné strany zbraně většinou! pravou rukou, anebo oboustranná, která mohou být ovládána z obou stran zbraně, pravou nebo levou rukou.Known embodiments of containment! maiftani® ·· can be constructed, bud. as, one-sided, ie they can be controlled from one side by weapons mostly! with the right hand or double-sided, which can be operated from both sides of the weapon, with the right or left hand.

Jednostranné^{1 2} provedení sestává obvykle ze zádržky, zpruhy, upevňovacího elementu a-ovládacího'tlačítka, oboustranné provedení sestává většinoui ze zádržky, vahadla, uloženého na kolíku; vratných zpruh a ovládacího tlačítka.The one-sided ^{1 2} embodiment usually consists of a retainer, a strap, a fastening element of an α-control button, the two-sided embodiment consists mostly of a retainer, a rocker, mounted on a pin; return belt and control button.

Nevýhodou těchto konstrukcí je tvarová složitost součástek, která má za následek zvýšení výrobních nákladů a neumožňuje použít kombinaci ocel-Al slitina pro velmi malé plochy styku součástky a protisoučástky.A disadvantage of these designs is the shape complexity of the components, which results in increased manufacturing costs and does not allow the use of a steel-Al alloy combination for very small contact surfaces of the component and the counterpart.

Podstata vynálezu spočívá v tom, že zadržovací mechanismus pro vyjímatelný zásobník automatické pistole sestávající z; pružené zádržky se záchytem vedené v rámu zbraně, vychylovacího lučíku a zásobníku, je vytvořen tak, že zádržka je opatřena vybráním pro záběr s válcovou plochou vychylovacího lučíku.It is an object of the present invention to provide a retention mechanism for a removable automatic pistol magazine consisting of; the spring retainers with the catch guided in the weapon frame, the deflector and the magazine are formed such that the detent is provided with a recess for engaging the cylindrical surface of the deflector.

Dalším důležitým význakem vynálezu je, že válcová plocha lučíku je ukončena ozubem. pno. záběr, s uatawQvacími vybráním, zá.ďržky při vychýlené poloze lučíku.Another important feature of the invention is that the cylindrical surface of the trigger guard is terminated by a tooth. pno. engagement, with recess recess, catches in the deflected position of the trigger guard.

Konečně posledním význakem vynálezu je, že vybrání odpružené zádržky svou plochou je ve styku s dorazem lučíku.Finally, the last feature of the invention is that the recess of the spring retainer by its surface is in contact with the trigger guard stop.

Zadržovací mechanismus pro vyjímatelný zásobník automatické pistole umožňuje snížit počet součástek oproti stávajícím známým mechanismům (např. u jednostranného provedení upevňovací element) a zjednodušuje výrobu (např. u oboustranného provedení je zádržka vhodná pro obrábění z tyče a její jednoduchost výroby ovlivňuje protlsoučástku).The retention mechanism for the removable automatic pistol magazine allows to reduce the number of components compared to existing known mechanisms (eg, a fastening element in a one-sided design) and simplifies production (eg in a double-sided design, the latch is suitable for rod machining and its ease of manufacture affects the counterpart).

Konstrukce mechanismu dále vytváří zvětšené plochy styku součástky a protisoučástky, což umožňuje použít kombinaci ocel-lehká slitina.Furthermore, the design of the mechanism creates increased contact areas between the component and the counterpart, allowing the use of a steel-light alloy combination.

SUBJECT

Retention mechanism for a removable automatic pistol magazine consisting of a spring-loaded detent guided in a frame, a deflector and a magazine, characterized in that the detent is provided with a recess (7) for engaging a cylindrical surface (5) of the deflector (3).

2. The retention mechanism of item 1 is; Fig. 5 is a side view of the recessed container and finally Fig. 6 shows in detail the detent.

In the front wall of the frame 1 an opening 13 is formed for the retainer 2 whose bottom 22 is provided in the rear wall of the frame 1 with a through hole

17. The holes 13 and 17 are coaxial.

The detent 2 with the control button 24 is guided by a cylindrical surface 12 in the opening 13 of the frame 1, by means of a pin. IX in the opening 17 of the frame 1, provided with a recess T with a cylindrical surface 20 and a surface 23. Further, the retainer 2 is provided with an alignment recess 21, 21. a catch 8 and an opening 16 in which a ring 15 is guided, the protruding end of which rests against the bottom. 22 of the opening 13 of the frame 1.

The magazine 10 with the recess 9, provided with the edge 25, is guided by the guide 18 of the frame 1 and the leading surface 19 of the retainer 2, terminated by the catch 8.

The trigger guard 3, pivotable about the pin 4, housed in the frame 1, is provided with a cylindrical surface 5, a tooth 6 and a stop 14.

The device according to the invention operates as follows:

When the cartridge 10 is inserted into the guide 18 of the frame 1, the front part of the cartridge 10 engages the lead-in surface 19 of the retainer 2, terminated by the catch 8, until the catch is in the extreme position.

8. detents. 2, under pressure of the straps / 15, engages in recesses 9 of the magazine 10. The weight of the magazine 10 thus retained rotates the retainer 2 in the direction of the force "Z", which prevents the cylindrical surface 5 of the trigger guard 3 from engaging with the cylindrical surface.

20 of the recess 7 of the detent 2, whereby the magazine 10 is held, in the recess 18, of the weapon handle. Dosednout; the areas · 23 of the recess, 7 of the retainer 2 to the stop 1A of the trigger guard 3 are prevented; - 2. from the hole · 13 of the frame 1. Recover 7 retainer. 2. thus defines the extreme axial positions; feed · trap 2.

When the magazine 10 is retracted, the trigger guard 3 cannot be deflected from the weapon.

By pressing the detent control button 24 with axial displacement of the detent 2 in the holes 13 and 17 in the direction "P" against the force of the straps 15, the engagement 8 with the edge 25 of the recess 9 of the magazine 10 is interrupted and the magazine 10 is released from the gun. After releasing the magazine from the weapon it is possible to swivel the trigger guard 3 in order to dismantle the weapon to a position where the tooth 6 is engaged with the locating recess

21 retainers 2.

BACKGROUND OF THE INVENTION characterized in that the cylindrical surface (5) of the trigger guard (3) is terminated by a tooth (6) for engaging an alignment recess (21) of the retainer (2) in the deflected position of the trigger guard (3).

Retention mechanism according to Claims 1 and 2, characterized in that the recess (7) of the spring catch (2) is in contact with the stop (14) of the trigger guard (3) by its surface (23).
