Definitions
- the present invention relates to a firearm of the rotary head closure type, comprising a housing part made of plastic or metal, a closure carrier guide made of metal, a closure carrier guided longitudinally displaceably by the closure carrier guide relative to the housing part, in which a closure head is rotatably mounted, and one of Housing part received locking bush made of metal, in which a barrel can be fixed and, in alignment with the barrel, the closure head is lubverriegelbar.
- firearms of the turret type are widely used as AR-10/15 army rifles, including the American M16 assault rifle.
- the housing part are usually made of plastic or light metal, eg aluminum.
- Heavily loaded parts such as barrel, locking bushing and lock carrier with bolt head, on the other hand, are made of steel. Due to the poor sliding properties of the steel of the closure support on the aluminum or plastic of the housing part intensive treatment with special lubricants is necessary. This leads to an additional sensitivity of the weapon against pollution by Pulverschmauch, sand, mud, ice, etc., whose particles adhere to the lubricant film and thereby substantially reduce the sliding action. Therefore, the M16 requires frequent and intensive cleaning to avoid malfunction.
- the Austrian patent no. 513,144 of the same Applicant discloses, for guiding the closure carrier in the housing part on the inner surface of the housing part slide rails made of a different material from the housing material to allow sliding of the closure carrier in the housing part with little or even completely without lubricant.
- the present invention sets itself the goal of the prior art continue to improve and create a firearm with high stability and precision.
- the lock carrier is guided securely in the lock carrier guide, so that its material pairing can be matched to one another with regard to good sliding properties and robustness.
- the run, locking bushing and closure can also be exchangeable, for example to exchange worn parts and / or one Caliber change to make an existing firearm.
- the lock carrier guide is connected to the locking bush via a tongue-and-groove connection which acts in a directionally stable manner in the longitudinal direction of the firearm.
- the lock carrier guide by screwing, welding, compression or the like. connected to the locking socket. In this way, a rigid connection in all directions of the lock carrier guide is made with the locking bush, leads to even greater stability of the firearm and also, depending on the design, either permanent or detachable.
- lock carrier guide is additionally positively and / or positively connected to the housing part. In this way, a secure fit of the lock carrier guide is ensured on the housing part.
- the precision of the firearm also in cooperation e.g. with an attached to the housing part target device is thereby increased. Furthermore, the forces absorbed by the closure carrier guide can be transferred specifically to the housing part.
- the closure carrier guide has a substantially C-shaped cross-section, the ends of the C each forming an inwardly directed rail, which rails engage in lateral longitudinal grooves of the closure carrier.
- Such a closure bearing guide formed in this way is easy to manufacture and already very stable in itself, whereby it can also be generated material and thus saving weight.
- the inwardly directed rails in cooperation with the lateral longitudinal grooves of the closure carrier, provide a permanently secure and precise sliding fit and thereby prevent tilting of the closure carrier in the closure carrier guide and consequently prevent jamming and / or damage to the firearm.
- the lock carrier guide has anchors to which a handle is attached directly. In this way, forces acting in particular in the longitudinal direction of the weapon directly to the handle part and a piston usually associated with this in such firearms Derived shoulder of a shooter. The housing part is thereby further relieved of force.
- the lock carrier guide is in this case a central element for connecting all essential for the function of the firearm parts.
- the closure carrier guide has an opening for the connection of a magazine shaft and the passage of a knock-off mechanism. In this way, the usual supply of ammunition and also a usual tee-off is ensured;
- a closure carrier guide has a frame-like structure, whereby weight is saved with comparable stability.
- FIG. 1 shows a firearm according to the invention of the rotary head closure type in an exploded view in perspective view obliquely from above;
- FIG. 2 shows a detail of the firearm of FIG. 1 in the region of the closure carrier guide in longitudinal section;
- FIG. 3 shows the detail from FIG. 2 in a rear view in the longitudinal direction of the firearm
- Figures 4 to 6 show the lock carrier guide of Figure 2 in a perspective view obliquely from above (Figure 4), in side view (Figure 5 ⁇ and in rear view (Figure 6);
- Fig. 7 shows the bolt carrier of the firearm of Fig. 1 in rear view.
- a firearm 1 has a housing part 2 and a handle part 3.
- the housing part 2 accommodates a locking bush 4, in which a barrel 5 from the front, e.g. by means of a bayonet coupling 6, can be fixed.
- the firearm 1 is e.g. a handgun, such as a semi-automatic or automatic rifle.
- the firearm 1 has a rotary head closure 7 with a closure carrier 8 and a closure carrier 8 in the at least rotatable, usually also slightly axially displaceably mounted closure head 9,
- the lock carrier 8 is. in a lock carrier guide 10 relative to the housing part 2 longitudinally displaceable, i. in the direction of the longitudinal axis L (FIG. 2) of the firearm 1, between a front end position in which the closure head 9 is rotationally locked in alignment with the barrel 5 in the locking bush 4, and a rear end position in which the closure 7 is opened , guided.
- the housing part 2 essentially serves to protect the mechanically movable elements of the firearm 1, e.g. of the rotary head closure 7, against contact and contamination, for contact protection against the hot run 5 and for attachment of attachments, e.g. On a Picatinny rail 11, to the firearm 1.
- the mechanically heavily stressed parts of the firearm 1 such as the barrel 5, the locking sleeve 4, the rotary head closure 7 and the closure carrier guide 10 of the housing part 2 - and also the Handle part 3 - be made of lightweight, mechanically less demanding material.
- the housing part 2 is made of aluminum or plastic, and the barrel 5, the locking sleeve 4, the rotary head closure 7 and the lock carrier guide 10 are made of steel.
- the handle part 3 comprises, in addition to a handle 12 and a piston 13, which may be optionally adjustable and / or combined into one member, a trigger 14 for actuating a knock-off mechanism 15 and a magazine shaft 16 for coupling a magazine 17 for feeding new ammunition to Cartridge bearing 18 (FIG. 2) of the barrel 5.
- closure carrier guide 10 The structure and effect of the closure carrier guide 10 will be described below with reference to FIGS. 2 to 7.
