Prerequisites for creating the invention

Various magazines for air rifles or pistols are known in the art.

Thus, in the current state of the art there is patent WO2007/057487 "Air rifle magazine" dated 2006, in the name of Mr. Eduardo ZORRILLA ARTERO, which relates to an air rifle magazine of the type comprising a substantially cylindrical drum including comprising a plurality of chambers arranged parallel to its axis in a circumferential alignment, the chambers being configured to receive corresponding bullets, said drum in turn being of a type that can be replaced from empty to full in a rifle, characterized in that, at least one permanent magnet is located within said drum which surrounds each and all chambers thereof and creates a magnetic field which attracts all bullets to said chambers to facilitate loading of the magazine, wherein said bullets are partially or wholly made of magnetic material attracted by said magnet .

Also known is the patent WO2017/125622 “Bullet charging system” dated 2016 in the name of the applicant company GAMO OUTDOOR, S.L., which relates to a bullet charging system for carbines with breaking action, containing a butt on which the camera is mounted, a barrel in which the camera is located for bullets, a magazine for bullets and articulation means, characterized in that it contains an elastic rod having a central part and two ends, which are placed in a chamber, a housing in which the central part of the elastic rod is located, moving back and forth inside the said housing, and the fact that it is attached to the cylinder, and the propellant connected to the elastic rod and located between the bullet to be charged and the elastic rod.

Brief description of the invention

The present invention relates to the field of air rifle magazines that have a drum in which bullets are stored.

The closest document is the aforementioned patent WO2007/057487.

The patent in question eliminates the problem of loading bullets using a drum that has magnets that attract the bullets.

On the other hand, the disadvantage is that, as stated in the patent itself, there is a possibility that “a second bullet may tend to enter a chamber already occupied by another bullet.”

The said patent is intended to prevent a second bullet from entering the bullet chamber and causing the air rifle to be negligently discharged with consequent risk.

Thus, these inventors developed a new magazine in which the drum rotates only if the inertial motion that occurs as a result of firing a rifle occurs. Therefore, only when the rifle is fired can inertial movement occur that will cause the cylinder to rotate to the next position where the next available bullet is located.

An object of the present invention is a bullet magazine for air rifles and pistols, of the type comprising an outer housing, within which is located a drum having chambers in which the bullets are located, a through hole extending at least partially through its axis of rotation into the drum, channel , through which passes a bullet stop, a connection and an axis around which the drum rotates, characterized in that it contains a gear mechanism located in the drum, containing a row of teeth, a tilting means, at least one latch in contact with at least at least one of said teeth, and a torsion spring that rotates the drum along the axis of rotation, and when in a rest position, the stop prevents rotation of the bullet prepared for loading into the air rifle; when the bullet is loaded into the rifle, the latch blocks one of the said teeth, and when the bullet is released and the resulting recoil of the shot, the tilting means moves and disengages the latch from the tooth, releasing the rotating drum, and the next bullet is blocked by the stop, making the next housing ready for loading the bullet.

Figure 12 shows the outer housing 1, chamber 5, inclined plate 10, push button 31, cover 21 and screw 22.

13a-13e show the inclined plate 10, chamber 5, tooth 8, latch 9, spring 12, groove 50 and rotation axis 51.

Figure 14 shows the cover 21 with an axis of rotation 51, a spring 12, an inclined plate 10 with its groove 50.

For clarity, bullet 23 is not shown in all drawings, although it should be understood that the bullet is a visible or invisible part of all drawings.

Thus, the device of the present invention consists of an outer housing 1, inside of which there is a drum 2. The drum includes a number of chambers 5 in which bullets 3 are placed.

There is a through hole 6, which extends at least partially (it may be a blind hole) through its axis of rotation to the axis of rotation of the drum into the drum 2. The drum 2 rotates around the axis 4 of rotation.

Similarly, in the drum 2 there is a channel 17 (Fig. 10), through which a limiter 30 passes, which is the end of the course of the bullets 23, and an elastic connection 18, which holds and rearranges the bullets 23 in the chambers 5.

In addition, in the drum 2 there is a gear mechanism 7, which contains a number of teeth 8 with which the latch 9 will engage, as will be explained below.

In addition, there is a tilting means 11, 12, an inertial mass and a spring 12.

Thus, the device includes at least a latch 9, which in this embodiment, for ease of understanding, is just one latch 9. Based on tolerance, the latch 9 may not be in contact with the tooth 8 until the bullet 23 will not be loaded into the bullet chamber 25 of the air rifle 14.

In the case in which the calculations have been adjusted, the latch 9 will be in contact with at least one of said teeth 8, locking the drum 2 from the moment the bullet 23 is blocked by the limiter 30, in a synchronous manner.

Likewise, the device contains a torsion spring 13, which rotates the drum 2 around an axis 4 of rotation.

Thus, when in a resting position, the stopper 30 prevents the bullet 23 and therefore the drum 2 from rotating. The bullet 23 is then prepared for placement in the bullet chamber 25, for example in the same manner as described in the present applicant's patent WO2017/125622.

When the bullet 23 is placed inside the bullet chamber 25 of the air rifle 14, the stopper 30 stops preventing rotation of the drum 2, and once the drum 2 moves slightly, the latch 9 locks one of said teeth 8, preventing rotation of the drum 2.

If the user cannot remember whether he has loaded or not loaded the bullet 23 into the bullet chamber 25, even if he performs the maneuver, the bullet 23 will not be loaded because there are no bullets 23 in the chamber 5 that faces the bullet chamber 25. since the bullet 23 is inside the bullet chamber 25 and the drum 2 does not rotate to load a new bullet.

Therefore, with this invention, loading of two or more bullets 23 inside the bullet chamber 25 is prevented, which was not achieved in the prior art as explained in the specification itself.

When a bullet is fired from the bullet chamber 25, the tilting means 11, 12 are moved by the recoil of the shot and disengage the latch 9 from the teeth 8, likewise releasing the drum 2, which rotates to stop the next bullet 23 when its passage is blocked by the stopper 30.

In addition, the tilting means 11, 12 returns to its original position.

The gear mechanism 7 can optionally be a ratchet mechanism having sawtooth teeth 8.

Unlike the proximate document, in this case the ratchet mechanism serves as a block when there are no more cartridges, while in the proximate document it served to move the drum forward and prepare the next cartridges.

Optionally, the teeth 8 are located around the through hole 6.

In one embodiment, the magazine 3 contains an inclined plate 10, on which the tilting means 11, 12 and the latch 9 are located (Fig. 2-5).

The tilting means contain an inertial mass 11, which causes the inclined plate 10 to rotate under the influence of inertia created by the shot (during recoil).

When turning the inclined plate 10, tooth 8 will be released and will rotate drum 2 under the action of torsion spring 13.

Then the spring 12 rotates the inclined plate 10 in the opposite direction until it reaches the initial position, that is, with the bullet 23 blocked by the limiter 30.

In the embodiment, as shown in Figs. 1-5, the inertial mass 11 is located perpendicular to the chambers 5.

The tilting means may include a push button 31 connected to the tilt plate 10. When the push button 31 is actuated, it pushes the tilt plate 10 to discharge the bullet magazine.

If, at the end of using the rifle, a number of bullets still remain inside the magazine 3, the user will not be able to remove such bullets, since without inertial movement the latch 9 blocks the drum 2.

When the push button 31 is pressed, the inclined plate 10 moves and moves the latch 9 away from the teeth 8, thereby causing the drum 2 to rotate. Therefore, when the next bullet 23 rotates, it will be stopped by the stopper 30 and thus the user can remove the bullet manually, and similarly, the remaining bullets remaining inside drum 2.

The inventors have noticed that sometimes users use or replace accessories that change the overall weight of the rifle, which causes the rifle or pistol to change the recoil when fired, and this can affect the movement of the ramp plate 10.

This causes the ramp plate 10 to move when firing and disengage the latch 9 (which is secured to the ramp plate 10) connected to tooth 8, but the ramp plate moves quickly enough to restore its original position, again locking the latch 9 to the same tooth 8 before reel 2 can turn. This is because the drum 2 has to move the bullets that are stored in the drum 2, and therefore the rotation of the drum 2 takes more time than the time required to return the inclined plate 10 to its original position.

If the rifle is calibrated this problem will not occur. However, the problem arises when the carabiner is no longer calibrated due to the addition or removal of additional accessories.

Therefore, the inventors have further introduced the possibility of increasing the time for returning to the original position by delaying the time required for the inclined plate 10 to restore the original position (Fig. 13a).

Thus, as shown in the example of Fig. 2, the tilting means contains an inertial mass 11, which causes the tilting plate 10 to rotate and move under the influence of inertia when fired, thereby disengaging the tooth 8 and causing the drum 2 to rotate. In addition, the tilting means includes a spring 12 connected to a groove 50 located in the inclined plate 10. Within the groove 50 there is a rotation axis 51, such rotation axis 51 of the inclined plate 10 being located at one end of the groove 50 when the latch 9 locks one of the teeth 8, and the axis of rotation 51 is at the other end of the slot 50 when the latch 9 is disengaged from the tooth 8.

Optionally, in this embodiment, the groove 50 is oriented toward the central region of the ramp plate 10, determining that the ramp plate 10 moves from bottom to top and vice versa.

As a manufacturing option, it is provided that the outer housing 1 is closed by a cover 21, wherein said rotation axis 51 is formed integrally with said cover 21. Thus, the cover 21, which is secured to the outer housing 1 by a screw 22, the rotation axis 51 does not move, and it is the inertial mass 11 when fired, which causes the inclined plate 10 to move, and the movement of the inclined plate 10 is directed by the groove 50, within which the rotation axis 51 is located.

In other embodiments, the teeth 8 are located on the outside of the drum 2 (Figs. 7-11).

In addition, the tilting means contains an inertial mass 11, which pushes an inertial element 20, which ends on the latch 9, pressing such an inertial element 20 against the cover 21 of the magazine 3, and such a cover is initially separated from the said inertial element 11 at a predetermined distance 19 under the influence of inertia when fired.

This causes tooth 8 to release, turning drum 2.

Then, the spring 12, supported by the cover 21, pushes the inertial element 20 in the opposite direction, locking the latch 9 on the next tooth 8a and again separates the inertial element 20 from the cover 21 by the said predetermined distance 19.

Said predetermined distance 19 is greater than the height of the latch 9, that is, the latch 9 must have an area sufficient to unlock tooth 8 and be able to unlock the next tooth 8a.

In this embodiment, to reduce the area, the inertial mass 11 is located inside the inertial element 20, so that when recoil occurs after the shot, the inertial mass 11 presses the inertial element 20 against the cover 21.

The inertial element 20 may include a protruding portion 16 that presses the spring 12 against the cover 21 when the inertial mass 11 pushes the inertial element 20.

Likewise, when the spring 12 is stretched, it pushes the protruding part 16, which, when connected to the inertial element 20, causes the inertial element 20 to move uniformly to its original position.

The inertial mass 11 is located perpendicular to the chambers 5 to facilitate the release of the latch 9 when the magazine is located vertically.

Likewise, in the case where the magazine is positioned horizontally, as explained above, this embodiment also includes a push button 24 which, when actuated, releases the latch 9 and unlocks the tooth 8.

That is, to release the bullet 23 from the magazine 3, it is necessary to press the push button 24 against the cover 21, thereby releasing the latch 9 from the tooth 8, allowing the drum 2 to rotate and allowing the next bullet to reach the stop 30. Said bullet 23 can be removed manually, and the same operation can be performed with the following bullets until the magazine 3 is empty.

Thus, if the magazine 3 is a horizontal type as in Figs. 1 to 5, the operation will be as follows.

Magazine 3 will be inserted into an air rifle 14, also known in English as an "air rifle", although it can also be an air pistol.

The rifle 14 will then be broken and the bullet 23 will be inserted into the bullet chamber 25, for example, in the manner described in the present Applicant's patent W02017/125622.

When the bullet 23 is inserted into the bullet chamber 25, the latch 9 locks the tooth 8 and prevents the drum 2 from rotating.

If the user wants to load another bullet 23, he will not be allowed to do so, since there will be no bullets in the chamber 5, since the drum 2 will not rotate.

After the rifle 14 is fired by the user and the rifle 14 recoils, an inertial movement occurs which causes the inertial mass 11 to move backward and rotate the inclined plate 10, which, when connected to the latch 9, moves the latch 9 and releases the tooth 8, thereby allowing the rotation of the cylinder 2 .

The drum 2 is rotated until the next bullet 23 reaches the stop 30 and stops, and thus the bullet 23 is ready for the user if he decides to reload the rifle 14.

In the embodiment of Fig. 13a-e, before the shot occurs, the latch 9 locks the tooth 8, thus preventing the rotation of the drum 2. The drum 2 applies a force to the inclined plate 10, moving the groove 50, which is made integral with the inclined plate 10 until it reaches the axis of rotation 51 (Fig. 13a).

Then, when the user fires, the latch 9 releases the tooth 8, thereby allowing the drum 2 to rotate. In addition, the drum 2 stops applying force to the slant plate 10 and thus causes the slant plate 10 to rotate using the rotation axis 51 and under the action springs 12 (Fig. 13b). It should be mentioned that at this point in time, reel 2 has not yet moved.

Then, the spring 12 causes the inclined plate 10 to move along the groove 50 due to the axis of rotation 51 (Fig. 13c). This movement along the groove 50 prevents the latch 9 from re-engaging with the tooth 8 in the same position when the rotation of the inclined plate 10 begins under the action of the spring 12 (Fig. 13d). Drum 2 has not yet moved, but it starts moving immediately after FIG. 13d ends and before FIG. 13e begins.

Finally, the drum 2 can thus move forward to the next bullet, since the latch 9 no longer blocks the same tooth 8, but it will immediately block the next tooth (Fig. 13e) and gives way to the next chamber 5 with a new bullet. This ensures that even when the user has unbalanced the carbine or pistol by introducing or removing additional accessories, the drum 2 will continue to rotate until the next bullet is fired (FIG. 13a), as if it were a calibrated carbine or pistol.

In the case of a vertical magazine, as shown in FIGS. 7-9 and 11, the procedure will be essentially the same as above, with some differences due to the movement of the tilting means from a horizontal to a vertical position.

Thus, loading the bullet 23 is essentially similar to the explanations regarding the magazine 3 in a horizontal position, as described in the patent WO2017/125622 of the same applicant.

Likewise, when the bullet 23 is inside the bullet chamber 25, the latch 9 is located in the tooth 8 so that the rotation of the drum 2 is prevented, and therefore a new bullet 23 cannot be placed or prepared for loading into the bullet chamber 25.

When the rifle 14 is fired and recoils, the inertial mass 11 pushes the inertial element 20 to the cover 21, removing the latch 9 from the tooth 8, which occupies a given area 20, allowing the drum 2 to rotate, and the new bullet 23 is blocked by the limiter 30, which is located for charging .

At the same time, when the inertial mass 11 pushes the inertial element 20, the protruding part 16, which is connected to the inertial element 20, presses the spring 12 against the cover 21, and when the spring 12 is released, it pushes the protruding part 16, which pulls the inertial element 20 and places the latch in the new tooth, locking drum 2 again.

The present invention describes a new bullet magazine for air rifles and pistols. The examples mentioned herein do not limit the present invention; therefore, it may have various uses and/or modifications, all of which are included within the scope of the following claims.
