Definitions
- the present invention relates to a breech block for a drop-down barrel weapon with at least one firing pin, which is guided to be axially displaceable therein and which has an impact head at its rear end for a firing piece to strike against and a firing tip at its front end for firing a cartridge, and also a block lock with such a breech block.
- a breech block of this type is known from patent EP 0 855 569 or EP 0 862 038, for example.
- patent DE 94 620 C discloses two levers, which are spring-loaded on the breech block and pivot in front of (and around) the firing pin ends in a scissor-like arrangement that can be forced open by a control rod in order to move the levers downwards out of the impact area of the hammer.
- the aim set by the invention is to provide a safety system for a drop-down barrel weapon with block lock, which is simpler, less susceptible to failure and is substantially safer than the known designs.
- This aim is achieved with the breech block of the aforementioned type, which is distinguished according to the invention in that a safety slide is guided in a transversely displaceable manner in a recess on the firing piece side of the breech block between a first position, in which it projects beyond the impact head of the firing pin in the impact area of the firing piece, and a second position, in which it is pulled back from the impact area of the firing piece, which recess is at least partially closed by a cover plate, wherein the cover plate has recesses for the impact head and the spacer head to pass through.
- the invention proposes a novel safety system concept for the first time that is directly integrated into the breech block. This results in a particularly space-saving, encapsulated safety system that is less susceptible to failure and is directly in the impact area of the firing pieces and thus at the end of the entire release sequence of the firing mechanism, i.e. it can prevent an unintentional firing of the cartridge in a safe manner without any additional space requirement, even if all prior safety mechanisms fail.
- the safety system concept of the invention is thus also particularly suitable for combining with conventional safety systems as a “double” or “last” safety mechanism.
- the design according to the invention enables the breech block to be fabricated particularly simply substantially in one piece, and the cover plate can be used at the same time for assembly of the firing pins and the safety slide.
- the safety slide can overlap the impact head of the firing pin.
- the safety slide has a spacer head for each firing piece, which spacer head lies directly next to the firing pin in said first position and thus, when viewed in the axial direction of the firing pin, projects further than its impact head. This securely prevents the risk of an unintentional contact of the impact head as a result of material elasticity and bending effects during impact of the firing pieces: the spacer head of the safety slide lies as solid spacer between the struck firing piece and the firing pin.
- the safety slide is preferably biased by a spring in the direction of the first position, as a result of which safety can be increased even further.
- the safety slide has a ramp for a control rod for its displacement.
- the safety slide can be controlled from a remote location, e.g. from an operating element on the handle of the stock, which displaces the safety slide via the control rod.
- the invention also provides a block lock for a drop-down barrel weapon with a breech block of the type according to the invention and a link with at least one firing piece, which during firing strikes against the safety slide or its spacer head in the first position of the safety slide and strikes against the impact head of the firing pin in the second position of the safety slide.

Abstract
Description
- This application is the U.S. National Phase of International Application No. PCT/AT2007/000018 filed on Jan. 18, 2007, the disclosure of which is incorporated herein by reference.
- The present invention relates to a breech block for a drop-down barrel weapon with at least one firing pin, which is guided to be axially displaceable therein and which has an impact head at its rear end for a firing piece to strike against and a firing tip at its front end for firing a cartridge, and also a block lock with such a breech block.
- A breech block of this type is known from patent EP 0 855 569 or EP 0 862 038, for example.
- Numerous systems are already known to secure block locks against unintentional release such as, for example, catch hooks for the firing pieces, holding devices for the tension springs etc., which are disengaged to release the safety mechanism of the weapon.
- Thus, patent DE 94 620 C, for example, discloses two levers, which are spring-loaded on the breech block and pivot in front of (and around) the firing pin ends in a scissor-like arrangement that can be forced open by a control rod in order to move the levers downwards out of the impact area of the hammer.
- All known safety systems require an increased expenditure with respect to the firing mechanism and, moreover, with particularly intense vibrations of the weapon, there is the risk of the catch hooks, levers, scissor arrangements etc. becoming detached again as a result of the lever-like effect of their moments of inertia, and this is an extremely dangerous situation. Moreover, the known safety systems require a considerable amount of space in the lock housing that is often not available, and are exposed to fouling that impairs their operability.
- The aim set by the invention is to provide a safety system for a drop-down barrel weapon with block lock, which is simpler, less susceptible to failure and is substantially safer than the known designs. This aim is achieved with the breech block of the aforementioned type, which is distinguished according to the invention in that a safety slide is guided in a transversely displaceable manner in a recess on the firing piece side of the breech block between a first position, in which it projects beyond the impact head of the firing pin in the impact area of the firing piece, and a second position, in which it is pulled back from the impact area of the firing piece, which recess is at least partially closed by a cover plate, wherein the cover plate has recesses for the impact head and the spacer head to pass through.
- The invention proposes a novel safety system concept for the first time that is directly integrated into the breech block. This results in a particularly space-saving, encapsulated safety system that is less susceptible to failure and is directly in the impact area of the firing pieces and thus at the end of the entire release sequence of the firing mechanism, i.e. it can prevent an unintentional firing of the cartridge in a safe manner without any additional space requirement, even if all prior safety mechanisms fail. The safety system concept of the invention is thus also particularly suitable for combining with conventional safety systems as a “double” or “last” safety mechanism. Moreover, the design according to the invention enables the breech block to be fabricated particularly simply substantially in one piece, and the cover plate can be used at the same time for assembly of the firing pins and the safety slide.
- The safety slide can overlap the impact head of the firing pin. However, it is particularly advantageous if according to a further feature of the invention the safety slide has a spacer head for each firing piece, which spacer head lies directly next to the firing pin in said first position and thus, when viewed in the axial direction of the firing pin, projects further than its impact head. This securely prevents the risk of an unintentional contact of the impact head as a result of material elasticity and bending effects during impact of the firing pieces: the spacer head of the safety slide lies as solid spacer between the struck firing piece and the firing pin.
- The safety slide is preferably biased by a spring in the direction of the first position, as a result of which safety can be increased even further.
- In any case, it is particularly advantageous if the safety slide has a ramp for a control rod for its displacement. As a result, the safety slide can be controlled from a remote location, e.g. from an operating element on the handle of the stock, which displaces the safety slide via the control rod.
- In a further aspect, the invention also provides a block lock for a drop-down barrel weapon with a breech block of the type according to the invention and a link with at least one firing piece, which during firing strikes against the safety slide or its spacer head in the first position of the safety slide and strikes against the impact head of the firing pin in the second position of the safety slide.
- The invention shall be explained in more detail below on the basis of an exemplary embodiment shown in the attached drawings:
-
FIG. 1 is a sectional view of a block lock for a drop-down barrel weapon (only shown in sections) in the open position; -
FIG. 2 is an exploded perspective view of the breech block of the invention; and -
FIGS. 3 and 4 are two schematic side views showing the interaction of the breech block with the firing pieces of the links, i.e. in the secured position (FIG. 3 ) and in the safety-release position (FIG. 4 ). - A drop-down (“tip-up”)
barrel weapon 1 is shown in sections inFIG. 1 , i.e. only in the region of its (here: open) block lock. The block lock comprises alink 2 and a mount 4 articulated thereto at 3 to accommodate twobarrels 5 and abreech block 6, which is guided to be transversely displaceable on the mount 4, as is known in the art. -
FIG. 2 shows thebreech block 6 in detail. Thebreech block 6 contains twofiring pins 7 guided displaceably in axial direction. Eachfiring pin 7 has animpact head 9 on its rear side for one respective firing piece 11 (FIGS. 3 and 4 ), which is guided in guides 13 (FIG. 1 ) of thelink 2 and is biased for firing, as is known to the person skilled in the art. On its front side eachfiring pin 7 has afiring tip 14 for firing a cartridge (not shown) in thecartridge storage areas 15 of thebarrels 5. - The
firing pins 7 are guided in steppedholes 16 of thebreech block 6 and respectively biased towards thefiring pieces 11 by apressure spring 17 supported between a step of thehole 16 and a shoulder of thefiring pin 7. Thefiring pins 7 are held by acover plate 18, which is inserted into a cut-out 19 of thebreech block 6 and is secured there by means of ascrew 20. Theimpact heads 9 of thefiring pins 7 thus pass throughrecesses 21 of thecover plate 18. - A
safety slide 22 is displaceably guided transversely to the direction of movement of thefiring pins 7 in the cut-out 19 of thebreech block 6 under thecover plate 18. Thesafety slide 22 has twospacer heads 23, which respectively pass throughrecesses 24 of thecover plate 18 and project beyond the plane of theimpact heads 9 of thefiring pins 7 when they are located in the impact region of thefiring pieces 11. -
FIGS. 3 and 4 show this in detail. In the secured position of the weapon shown inFIG. 3 , thesafety slide 22 is located in its first upper position, in which its spacer heads 23 project into the impact region of thefiring pieces 11 and securely space these from theimpact heads 9 of thefiring pins 7 in the struck or impact position. Thespacer heads 23 are thus placed or clamped between thefiring pieces 11 and thebreech block 6 in the manner of a wedge. - In the safety-release position of the weapon shown in
FIG. 4 , thesafety slide 22 is located in its second lower position, in which itsspacer heads 23 are removed from the impact region of thefiring pieces 11, so that these can strike against theimpact heads 9 of thefiring pins 7 unhindered. - Instead of the shown wedge effect, in a simplified variant the safety slide could also project beyond the
impact heads 9, i.e. overlap these, in its sliding direction. However, the shown embodiment is more favourable, in which the safety slide lies next to the firing pins and projects in the axial direction thereof in order to prevent any risk of contact of the impact heads. - According to
FIG. 2 , thesafety slide 22 is biased in the direction of its first secured position by means of a (schematically shown)pressure spring 25. Thepressure spring 25 is supported on one side against aside wall 26 of the cut-out 19 and on the other side against the underside of thesafety slide 22 and is partially received in adepression 27 of the cut-out 19. - In addition, the
breech block 6 is provided withlateral control studs 28, which cooperate with corresponding link guides in thelink 2 in a known manner in order to slide, when the mount 4 tips downwards, into the open position shown inFIG. 1 , in which thecartridge storage area 25 is accessible and can be emptied by means of acartridge extractor 26 and loaded again. -
FIG. 4 shows the mechanism for operating thesafety slide 22 in detail. Anoperating slide 29 mounted on thelink 2 or the housing of the weapon (not shown) controls alever 31 over aguide face 30, said lever being articulated to thelink 2 at 32 and moulded to form a control rod 33 at its other lever arm. The control rod 33 presses against a ramp 34 (FIG. 2 ) of thesafety slide 22 in order to move this downwards against the force of thespring 25 into its safety-release position when theoperating slide 29 is pushed forwards. - The invention is not restricted to the shown exemplary embodiments, but covers all variants and modifications that fall within the framework of the attached claims.
