Definitions
- Locking device in particular for small arms
- the invention relates to a locking device, in particular for small arms, with a locking piston which pushes a cartridge into a cartridge chamber and which has at least two radially projecting locking elements, and with a locking housing which has a longitudinal extension of the locking piston bore per locking element, which opens into an extension into which the locking element can be rotated and which has a support surface that can be gripped behind.
- a locking device in particular for small arms, with a locking piston which pushes a cartridge into a cartridge chamber and which has at least two radially projecting locking elements, and with a locking housing which has a longitudinal extension of the locking piston bore per locking element, which opens into an extension into which the locking element can be rotated and which has a support surface that can be gripped behind.
- Such locking devices so-called bayonet locks are common in a variety of handguns.
- the object of the invention is therefore to design a closure device of the type mentioned at the outset in such a way that the locking clearance is filled and the closure piston bore is better sealed.
- extension is designed as an annular space in which a closure sleeve is rotatably arranged between an open and a locked end position of the closure piston, and in that the closure sleeve per locking element has an extension which in the open end
- REPLACEMENT LEAF position is aligned with the expansion of the locking piston bore.
- closure sleeve completely fills the annular space and the cavity of the closure sleeve itself is filled by the inserted piston head.
- the rear end face of the closure sleeve also covers the longitudinal extensions of the closure piston bore.
- a preferred embodiment of the invention provides that in the closure housing there is a latching element which is spring-loaded to the axis of rotation of the closure sleeve and one on the circumference of the closure sleeve locking recess defining the open end position are provided.
- a latching element which is spring-loaded to the axis of rotation of the closure sleeve and one on the circumference of the closure sleeve locking recess defining the open end position are provided.
- annular space and the closure sleeve have conical sealing surfaces on the cartridge bearing side, wherein preferably a sealing element can also be provided between the sealing surfaces, which has the shape of a conical one Has sleeve.
- the closure housing has at least one gas outlet opening that opens into the annular space on the circumference. This will effective if, due to a material defect, a malfunction or other deficiencies causing a gas to escape into the annular space, the gases could be kicked back into the bores of the sealing piston.
- FIG. 1 shows a longitudinal section through the lock housing in the locking area of the lock piston
- FIG. 2 shows an exploded view of the locking area of the lock piston
- FIG. 3 shows a section along line III-III of FIG. 1 with the lock piston locked
- FIG. 4 is a schematic front view of the unlocked closure sleeve from the position seen by the line IV-IV.
- a locking device forming a bayonet lock has a locking housing 1 adjoining the barrel 20 and a displaceable locking piston 8 which is provided with two, three, and possibly also a plurality of locking elements 4 on the circumference.
- the locking piston bore 2 is provided with a longitudinal extension 9, which opens into an extension formed by an annular space 5.
- the locking piston 8 pushed into the closed position can be rotated about the axis 3, the locking elements 4 being supported on the end face 6 of the annular space 5, so that the front end 22 of the locking piston 8 resting on the cartridge is formed in the end of the barrel 20 Cartridge chamber 19 is pressed in locked.
- the annular space 5 tapers towards the cartridge chamber 19 and has a conical sealing surface 7.
- a closure sleeve 10 is rotatably arranged, the bore 18 aligned with the closure piston bore 2 also has an enlargement 11 per locking element 4, so that the closure piston 8 pushed into the closed position completely fills the closure sleeve 10.
- the closure sleeve 10 is locked in two end positions by a locking element 12 which is pressed into circumferential locking recesses 13, 14 of the closure sleeve 10 by means of a spring 21.
- FIGS. 1 and 4 show the unlocked end position of the locking sleeve 10, in which the locking receptacle extensions 9 and 11 of the locking piston bore 2 and the locking sleeve 10 are flush with one another, and the locking element 12 is pressed into the locking recess 13.
- the locking sleeve 10 is also rotated, the locking element 12 snapping into the second locking recess 14 (FIG. 3).
- the locking elements 4 are supported on the support surface 6 (FIG. 1) of the annular space 5 and the conical part 15 of the casing of the closure sleeve 10 is pressed against the sealing surface 7.
- the sealing piston 8 fills the sealing sleeve 10, which in turn completely fills the annular space 5 and covers the extensions 9 of the sealing piston bore 2 (FIG. 3). Since the conical part 15 is pressed against the conical surface 15, the cartridge chamber 19 is sealed against the sealing piston bore 2.
- the annular space 5 is also provided with lateral gas outlet openings 17 (FIG. 1) so that, in the event of a malfunction, the gases do not escape through the sealing piston bore 2, but can exit through the openings 17.
