SUMMARY OF THE INVENTIVE CONCEPT

The present general inventive concept relates to the pellet loading systems in rifles with articulated barrels, even though it could also be understood to be included in any guns with an articulated barrel.

The closest document is Patent WO2017/125622.

As it was indicated in the closest document, one of the big problems at present with rifles with an articulated barrel, also called “break barrel”, when they have a pellet magazine, is that when the pellets are housed in the pellet magazine, any misalignment between the barrel and the magazine can damage the pellet at the time of shooting, because the pellet, once damaged, will have an erratic trajectory once outside the barrel.

Said invention is very useful because in one of its embodiments it allows a configuration of a magazine in the form of a revolver, which facilitates loading and shooting the pellets.

This configuration is usually used with rifles that use telescopic sight, which is very common in countries like the USA.

In other countries the sportsmen prefer to use open sight (rear and front sight), such as for example, Spain, which means that using the revolver like magazines is discarded because they do not allow visual alignment of the line of fire through the magazine, from the sight.

To solve this problem the inventors have invented a system wherein, in rest position, with the rifle or air gun or CO2 gun, ready to fire, and the barrel closed, the magazine is hidden in a structure, not interfering to the view of the firing line from the sight.

To load the rifle or gun, the barrel is articulated or collapsed and meanwhile the magazine is moved towards the pellet chamber to which it lies opposite.

Subsequently, when the barrel is closed, the magazine moves towards its initial position, which is that of lying in connection with the barrel, allowing the sportsman's view and not interfering with the rear and firing line.

The pellet of the magazine is positioned inside the pellet chamber by a pushing means. Said pellet is placed in the magazine when the barrel is breaking at maximum, or a moment before or a moment after.

The foregoing and/or other features and utilities of the present general inventive concept may be achieved by providing system for loading system, used in rifles with a articulated or “break barrel” type barrel, of the type comprising a stock on which a chamber can be fixed, the chamber ending externally with a fork wherein the barrel is articulated, the barrel comprising a pellet chamber, a pellet magazine and articulating means, characterized in that the system can comprise: a first structure with a central section and two ends which are housed in the fork in the chamber, a support wherein the central section of structure with forward and reverse movement thereof is positioned, at least partially, a housing for the magazine, a pushing means, linked to the structure, arranged on the support; the magazine (12) being laid on barrel (3), with barrel (3) is closed and the magazine (12) being faced to the pellet chamber (5) with barrel (3) at the moment of the barrel break trajectory, with a pellet (13) placed in front of said pellet chamber (5) at the end of the break trajectory.

In an exemplary embodiment, when magazine (12) can be positioned in front of pellet chamber (5), pushing means (11) can be positioned in front of pellet (13) which, in turn, can be positioned in front of pellet chamber (5) and during the break movement of barrel (3), pushing means (11) can be in front of pellet (13) and said pushing means (11) insert the pellet (13) into pellet chamber (5) and then said pushing means (11) can be returned to the initial position when barrel (3) closes, the magazine (12) is returned to its lying down position and leaving the rifle loaded

In another exemplary embodiment, the system can be characterized in that at the end of the breaking operation of barrel (3), pushing means (11) can be positioned in front of pellet (13), and at the moment when the barrel (3) is closing, said pushing means (11) insert the pellet (13) into the pellet chamber (5), with said pushing means (11) then returning to their initial position, and with magazine (12) returning to its lying down position, leaving the rifle loaded.

In another exemplary embodiment, the system can include a body (10) articulated to barrel (3), and in that the housing (100) for magazine (12) can be articulated to the body (10).

In another exemplary embodiment, the system can be characterized in that the housing (100) for magazine (12) can be articulated to support (101) and to body (10).

So, in a specific embodiment the pellet loading system, is one of those used in rifles with articulated or “break barrel” type barrels, the same type of barrel as those shown in the figures accompanying this application.

It comprises a stock 1 on which there is attached chamber 2 ending externally with a fork 102 where there is articulated a barrel thanks to articulating means 4.

On barrel 3 there is positioned pellet chamber 5, which is the place where the pellet to be fired is positioned after being removed from magazine 12 or pellets 13.

The invention comprises a first structure 6 which is configured by a central section 9 and two ends 7, 8. Said two ends 7, 8 are housed in fork 102 of chamber 2.

It has, also, a support 101 where there is positioned, at least partially, central section 9 of first structure 6. Said first structure 6 also has a forward and reverse movement, when barrel 3 collapses and closes, as will be indicated later.

A housing 100 is configured for placing magazine 12, with said housing 100 having a movement with respect to barrel 3 which means that magazine 12 can change position without moving with respect to said housing 100, as will be explained below.

The system, in its basic configuration, has a pushing means 11, linked to first structure 6, arranged on support 101. In an optional embodiment, pushing means 11 is inside support 101.

This way when barrel 3 is in the closed position, magazine 12 remains lying on barrel 3, leaving free the rear sight 122 and the firing line for the shooter.

On the other hand, when the barrel 3 collapses, the magazine 12 moves together with the housing 100 until it lies facing said magazine 12 in pellet chamber 5. This makes it easier to subsequently insert pellet 13 into magazine 12 inside pellet chamber 5.

One of the embodiment comprises the fact that when magazine 12 is facing pellet chamber 5, at the same time pushing means 11 is in front of the pellet 13 which, in turn, is in front of pellet chamber 5. This way when barrel 3 collapses, pushing means 11 is in front of pellet 13 and said pushing means 11 inserts the pellet 13 into pellet chamber 5. Pushing means 11 will return to the initial position when barrel 3 closes, with magazine 12 returning to its lying down position and leaving the rifle loaded.

Another embodiment could be that when the collapsing manoeuvre of barrel 3 finishes, pushing means 11 ends up in front of pellet 13, and subsequently, when barrel 3 closes said pushing means 11 inserts pellet 13 into pellet chamber 5, said pushing means 11 then returning to the initial position, and magazine 12 returning to its lying down position, leaving the rifle loaded.

Optionally, body 10 is articulated to barrel 3, with housing 100 for magazine 12 articulated to said body 10.

Also, in another embodiment the housing 100 for magazine 12 is articulated to the support 101 and to the body 10 although also it could be support 101 articulated to housing 100 and to body 10.

Pushing means 11, optionally could be arranged inside support 101, protected inside side support 101 as indicated above.

To facilitate the movements of support 101 and the rotation and movement of second rotation axis 125, support 101 comprises guiding pins 103 which are positioned on some guides 104, belonging to body 10 along which they move.

In order to improve the return of magazine 12 progressively to the lying down position, housing 100 of magazine 12 can comprise some end stops 105 that act in the return movement on the outside of chamber 2 and which then guide the position changing movement of magazine 12.

The body 10, in order to increase its tolerance and facilitate the guiding movements, comprises damping means on body 10.

Said damping means comprise at least an axis with a second spring 123 (in this embodiment there are two of them) and damping guides 106. This way the body 10 has certain linear movement, to-and-fro, in the same direction as the shot, and this is absorbed by the second spring 123.

So, also it can have a second structure 107 which is connected to support 101 and to the barrel 10, leaving therefore said second structure 107 coordinated to first structure 6.

One of the manufacturing options is first structure 6 or second structure 107, or both of them, as a rod.

It has been found that as rod 107 is elastic this allows saving on the manufacturing costs, and also allows some greater tolerances, although they could be rigid.

This way, when the sporting rifle, also known as “air rifle”, has just fired, said rifle remains as shown in FIGS. 3a and 10, i.e., without a pellet 13 in pellet chamber 5.

The rifle does not need pellet 13 to be inserted manually by the sportsman, instead it has a magazine 12 which stores different pellets 13 which are loaded in pellet chamber 5 during the collapsing movements of barrel 3 and the closure thereof.

To load the pellet 13 from the magazine 12, the sportsman will break the barrel 3, as shown in FIG. 4 so that barrel 3 moves towards the perpendicular, in relation to chamber 2.

This means that magazine 12 moves from a lying down position (FIG. 1-3b) to a position wherein it lies facing the pellet chamber. In other words, as the barrel breaks, the magazine also moves (FIG. 4-7).

When barrel 3 closes, magazine 12 moves from the position in front of pellet chamber 5 to lie down again and not interfere in the vision between the sight 122 and the firing line.

In order to carry out said operations the rifle comprises a first structure 6 with a central section 9 and two ends 7, 8 which are housed in the fork 102 or the chamber 2.

The first structure 6, when barrel 3 breaks, rotates with respect to the fork 102 at the ends thereof 7 and at the same time its central section 9 pushes the pushing means 11 which is found on support 101, approaching it towards pellet chamber 5 due to the fact that the rotation radius of first structure 6 is shortened and this means that central section 9 pushes pushing means 11.

At the same time housing 100 which transports magazine 12 also starts a rotation movement, until magazine 12 ends up in front of pellet chamber 5.

In this embodiment the rotation is made by means of first rotation axis 124 and second rotation axis 125 which are coordinated, so that when one rotates in one direction the other one rotates in the opposite direction, which facilitates it being a controlled movement.

So, while the housing 100 with the magazine 12 move the movement to place themselves in front of pellet chamber 5, the support 101 with pushing means 11 make another movement to end up in front of the pellet 13 in the magazine 12 which has to be inserted into pellet chamber 5.

In one of the embodiment options when barrel 3 collapses completely, the pushing means pushes pellet 13 inside pellet chamber 5. Another possibility could be that when the manoeuvre for closing barrel 3 starts is when pushing means 11 inserts it or it could be before barrel 3 collapses completely.

In order to make the rotation movement with first rotation axis 124, a first spring 121 has been configured, whereby while barrel 3 is closed said first spring 121 is compressed, and when barrel 3 collapses said first spring 121 is released facilitating the rotation movement of magazine 12.

When the barrel 3 closes, first spring 121 is compressed and at the same time end stops 105 of body 10 rest on the chamber 2, this prevents the system from closing abruptly, unbalancing the various elements.

There are damping means for body 10, made up of damping guides 106 and second spring 123 which allow a to-and-fro movement of body 10, facilitating its positioning in the manoeuvres for collapsing and closing the barrel.

The housing 100 can adopt different configurations to secure the magazine 12 to the housing 100, such as for example a blocking mechanism for magazine 12 similar to a ski binding system, which would allow securing magazine 12 in the above-mentioned movements.

As shown in FIG. 8a, in order to facilitate the breaking and closing manoeuvres of barrel 3, the arrangement of guides 104 has been envisaged inside body 10 which guiding pins 103 run along that are integral to support 101, so that support 101 would have a controlled movement synchronized with that of body 10.

The second rotation axis 125 is connected to the support 101, and it is the one that articulates said support 101 and pushing means 11 as a result of the force applied on said pushing mean 11 by central section 9 of first structure 6.

When ends 7 of first structure 6 rotate in fork 102, said second rotation axis 125 allows support 101 to be placed correctly and consequently pushing means 11 would also be placed correctly when barrel 3 collapses; so, both would be placed correctly when the closing movement of barrel 3 occurs.

In another embodiment, as shown in FIGS. 9 to 13, the damping means are replaced by a second structure 107, which attaches to support 101 and to a fixed element of barrel 3, for example, the sight 122, creating the same effect of the manoeuvre explained above.

Said first structure 6 in the two embodiments and second structure 107, can adopt different configurations, as elastic rods, or rigid structures like splints.

This patent of invention describes a new pellet loading system. The examples mentioned herein are non-limiting of this invention, therefore it could have different applications and/or adaptations, all within the scope of the following claims.

Although a few embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
