Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a firing mechanism for a shotgun, commonly known as a breach block.
This firing mechanism is a single-block assembly that is easily detachable from the gun stock, based on a frame that houses a suitable firing mechanism therein and a trigger plate that mounts the firing mechanism.

The mechanism according to the invention is specifically designed for shotguns having two parallel barrels, commonly known as side-by-side shotguns. It is an object of the present invention to provide the fitting and disassembly work with maximum ease and speed, as well as optimal fit and stability in the operation or fitting conditions of the firing mechanism.

2. Description of the Related Art In the field of a double-barreled shotgun, a shotgun has the following firing mechanism. This firing mechanism has a trigger plate fixed to a guard that protects the trigger, on which a breach block rocker, left and right hammers, left and right hammer levers, and rockers for each hammer. And a rocker for each trigger and a counterweight, the assembly being housed in a frame conveniently mounted to the trigger plate.

This assembly with a breach block is then intended to be housed in the shotgun stock. That is, the trigger plate is flush with the lower surface of the stock,
A trigger guard projects therefrom, and the assembly is conveniently disassembled into the shotgun stock.

[0005] One common configuration within the scope of the parallel shotgun is to use a corresponding screw threaded to the shotgun stock at each end of the trigger plate that projects beyond the firing mechanism. Alternatively, an opening for penetrating a bolt is provided, and the trigger block is removed from the stock by removing the screw.

[0006] This configuration creates a problem with two forms. On the one hand, the relative difficulties involved in removing and replacing the screws, which often require the use of appropriate tools not available when needed. The other is corrosion that occurs when the trigger block is disassembled many times, where the screw is located in the shotgun stock,
This causes play and lack of adjustment in the firing mechanism.

With the aim of minimizing this problem, a complementary support on the stock is provided at the other end of the trigger plate, based on the provision of a hook on one of the ends of the trigger plate. Arrangements are known which are supplemented by a single screw. However, this configuration obviously only solves part of the problem, and the screw is still maintained as a last resort for securing the trigger block.

[0008]

The firing mechanism proposed by the present invention is intended for a parallel shotgun as described above, and provides a sufficiently satisfactory solution to the above-mentioned problems. provide.

[0009]

In order to accomplish this,
In particular, and based on the operating components described above, the features of the mechanism are based on the following facts. The trigger plate, on which the moving parts of the firing mechanism are mounted and whose frame surrounds the breach block, incorporates a latch at one of its ends, preferably at its front end. This latch is
In particular, it is intended to engage a mortise formed in the stock, at the front end of the housing for receiving the trigger block. On the other hand, at the other end of the trigger plate, another stop member formed in the stock is contracted against the tension of a spring acting as a member for locking the trigger plate.
And is slidably engaged therein. That is, an extension of the trigger plate provided on the trigger plate using a small key designed to form part of a shotgun accessory as a result of mere frontal pressure on the corresponding end of the trigger plate. With the safety button fully protected by, the stop member is biased to release the trigger plate.

In this way, the trigger block is fitted by applying the trigger plate by one of its ends and then the front pressure from the latter to the other end. On the other hand, when disassembling, it is sufficient to gently pull out the trigger guard while pressing the safety button for contracting the lock on the trigger plate.

To supplement the description provided, and to assist in understanding the greater portion of the features of the present invention by way of a preferred embodiment, a set of representations is shown in the non-restrictive manner illustrated to: The drawings are provided as an integral part of the above description.

DETAILED DESCRIPTION OF THE INVENTION Referring to these drawings, and in particular to FIG. 2, the firing mechanism proposed by the present invention is intended for a dual-barreled or parallel shotgun and has the following arrangement: It turns out that it has. That is, the trigger plate (1) to which the trigger guard (2) for the trigger (3) is attached is used as a base, and the oscillating body (4) of the bleach block and the left-side hammer (5) are provided thereon. And a right hammer (6), a left hammer lever (7) and a right hammer lever (8), a hammer rocker (9),
A spring (10), a top cap (11) for said spring, a rocker (12) of the trigger and a counterweight (13) are adapted. The structure and arrangement of these components can be changed without affecting the essence of the invention. This essence is, as mentioned above, concentrated on the means by which the assembly, in particular the trigger plate (1), is thereby attached to the stock.

In this regard, the trigger plate (1) incorporates at its front end a half-moon shaped latch (14) provided by the lower step of the trigger plate in the embodiment shown, but otherwise. It is clear that the shape can be applied.
This latch (14) is obviously a complementary step on the stock,
In particular, it is intended to engage the step (14 ') of the frame (15) shown in FIGS. This frame is intended to house the trigger plate (1) fixed in the housing of the gun and equipped with the appropriate firing mechanism. The trigger plate (1) is provided with the latch (1).
At the end opposite to 4), a locking member projecting laterally from the trigger plate (1), having a considerable recess, preferably with a curved / convex inclined front face, as a supplementary means of attachment. (16) is incorporated. This can be achieved by simply pressing the trigger plate (1) with various accessories against the stock, as can be seen in FIG. 3, between the locking member and the receiving mortise in the gun body, and in particular, This is to cause the connection with the frame (15) arranged in the mortise.

The locking stop (16) projects against this stop (16) and is always contracted against the spring (17) which is then affected by the side hole. Here, a small lateral hole (20) in the trigger plate is fixed to the stop (16) with the aid of an engaged screw (19) housed axially in said spring (17).
An externally adjustable shaft end (18) is accommodated therein. This shaft end or bolt (18) is
It is integrated with. The shoe is associated with an operating button (23) which engages a mortise (22) in the trigger plate and then projects outwardly through the base or underside of the trigger plate. This is to make the operation buttons operable.

As can be seen in FIG. 2, this release button for the firing mechanism is generally such that it is virtually impossible to accidentally or involuntarily operate it to disengage the mechanism. It is protected by the rear extension (24) of the trigger guard (2) for the trigger (3). To achieve this, as shown in FIG. 3, the locking member (16) is required to cause the lateral movement of the button (23) which is required to contract against the spring (17). To
It is necessary to have the assistance of a small foreign key (25).
