Description

The field to which the invention relates

(with an indication of the designation according to the International Patent Classification)

This invention relates to AIR WEAPONS.

According to the international classification of MKP, it is classified as: F 41 B 11/00.

Technical problem

(for the solution of which patent protection is requested)

Manufacturers of air weapons are constantly working on improving these sports-hunting weapons with the aim of producing the strongest, most accurate and efficient weapons of this type.

The strength, precision and efficiency of air weapons depend significantly on the power of the drive, consumption of the drive power, regulation of that power, and overall on the drive system. The limits of the strength, precision and efficiency of air weapons are constantly moving with various solutions and represent a permanently open process of improvement and improvement in the production and application of air weapons, to which this invention also contributes.

State of the art

(display of known solutions to a defined technical problem)

Known propulsion power solutions for air weapons are:

1. Spring Piston - Spring Piston

2. Piston with pneumatic insert - Gas ram

3. Pre-stored pressurized air - PCP

4. Drive with CO2

1.1 Spring Piston - Spring Piston

A piston with a spring - in English Spring Piston - is the generally accepted name for the drive of air weapons with a standard steel spring that drives the compression piston.

The spring is inserted into the compression piston and thus they are inserted together into the compression cylinder. The spring is compressed using the lever until the piston is engaged. Pulling the trigger releases the spring that drives the compression piston, which creates pressure in the compression cylinder that ejects the projectile. For each projectile firing, the same action must be repeated.

This type of airgun drive is characterized by a gradual weakening of the spring with use.

Air weapons with a standard spring, when fired, suffer from vibration, which has a negative effect on accuracy.

An air weapon with a standard spring can reach a speed of a standard lead projectile higher than the speed of sound and practically has an upper limit of about 380 m/s in 4.5 mm caliber.

2.1 Piston with pneumatic insert - Gas ram

A piston with a pneumatic insert - in English Gas ram - is the generally accepted name for a pneumatic insert that is placed in the compression cylinder in place of the standard spring by removing the standard spring.

It is a closed pneumatic mechanism under the pressure of compressed gas or air to create a spring effect. The gas or air inside this mechanism is closed and is constantly under the same pressure.

This type of airgun drive features consistent power, reduced recoil, and longer life than a standard spring.

Its disadvantage is a sudden increase in internal pressure during engagement, due to the narrow space in which air or gas is compressed, which creates greater resistance than a standard spring during engagement for the same drive power.

It is not possible to repair it, change the pressure or regulate the power as needed, and due to the complexity and precision of the production, it is significantly more expensive than a standard spring.

3.1 Pre-stored compressed air - PCP

Precharged Pneumatic or PCP - is a commonly accepted abbreviation for air weapons that use pre-stored pressurized air to propel a projectile.

The air is pre-stored under high pressure in a suitable cylinder or chamber, in larger quantities, so that it can be used to fire the projectile repeatedly. With this type of air weapon drive, the air is discharged through the valve directly to the projectile/diabolo when it is fired.

This type of drive for air weapons is characterized by inconsistency, gradual consumption of compressed air and weakening of the driving force with the firing of each projectile, impracticality of reloading and pumping, but also minimal vibration during firing, which has a positive effect on accuracy when shooting.

4.1 Drive with CO2

A CO2 drive uses cylinders pre-filled with CO2 gas, under pressure, usually for one-time use, i.e. not refillable.

Some more expensive models may use larger CO2 compression tanks, such as those used for colored marker balls in games.

This type of air weapon is characterized by inconsistency and gradual consumption of driving power, but also minimal vibration, which has a positive effect on accuracy when shooting.

Presentation of the essence of the invention using the following convenient terminology

(so that the technical problem and its solution can be understood, as well as stating the technical novelty of the invention in relation to the existing state of technology)

Appropriate terminology:

(which are appropriately and consistently used here for a more detailed description and precise explanation of the mechanical parts and functions of the invention, and are consistently used in the text with appropriate reference numerals)

1. The hollow coupling is a part of the pneumatic mechanism as an innovative element that connects two different drives, the drive of a standard spring and/or pneumatic piston, together or individually, with a compression piston by means of a compression lever-long or -short because it can accept a pneumatic cylinder with a pneumatic piston on both ends, thus enabling multiple types and variants of propulsion in the same air weapon.

2. The pneumatic chamber is a pressure chamber that is placed outside the compression cylinder and is connected to the compression cylinder by a hollow coupling. It is filled with compressed air that drives the pneumatic piston located in the pneumatic cylinder.

3. Compressed air is compressed air under high pressure in a pneumatic chamber that drives a pneumatic piston that acts on the compression piston via a long or short pressure lever.

4. The valve is a part of the pneumatic mechanism which, by pumping air into the pneumatic chamber or releasing air from the pneumatic chamber, enables the change and regulation of the pressure in the pneumatic chamber, that is, the change and regulation of the strength of the air weapon, thus enabling the complete emptying of the pneumatic chamber for the purpose of changing the drive, or combining drive, or in case of repair or servicing when worn rubber rings in the pneumatic mechanism need to be replaced.

5. A pneumatic piston is a driving piston in a pneumatic cylinder that, under the pressure of compressed air from the pneumatic chamber, acts on the compression piston via a pressure lever - long or short.

6. The pneumatic cylinder is the guide of the pneumatic piston which is under the pressure of compressed air from the pneumatic chamber, and it can be placed in the pneumatic chamber for the needs of double drive using the pressure lever-long, or in the compression cylinder for the needs of single drive using the pressure lever-short.

7. Pressure lever - is a long hollow working lever in the drive mechanism that is passed through the cavity of the hollow coupling and further through the cavity of the standard spring, and acts under the pressure of the pneumatic piston driven by compressed air from the pneumatic chamber, thus combining the power of the pneumatic piston and the standard spring which in this way together and simultaneously act with double force on the compression piston, and can also act independently without a standard spring.

8. The safety screw consists of three safety screws that, together with the screw on the underside, which connects the compression cylinder to the stock, keep the drive pressure securely attached to the compression cylinder and stock.

9. The compression cylinder is the part of the airgun body between the barrel and the stock in which the compression piston with a standard spring is located.

10. The compression piston is a standard piston in air weapons which, upon impact, after release, creates compression pressure in the compression cylinder, which ejects the projectile.

11. The stock spring is a standard airgun steel spring that is located partially in the compression cylinder and partially in the compression piston cavity.

12. Pressure lever – is a short short hollow working lever that is connected to a pneumatic piston that is connected to the drive of compressed air from the pneumatic chamber through a hollow clamp and thus acts, without a standard spring, independently and directly on the compression piston.

* Dual drive can have two meanings:

- may mean that the same air weapon has two different types of drives that operate individually; drive using

standard springs or drive using a pneumatic mechanism.

- can mean that in the same air weapon, two different drives operate simultaneously as one, double drive.

Idea:

Place an additional pneumatic drive mechanism, outside the compression cylinder, connect it using a hollow coupling and a pressure lever to the existing drive mechanism and thus create a larger space for the accommodation of a second and/or stronger drive mechanism that can act in combination with a standard spring as a double drive, of course stronger , and that it can act independently as a single pneumatic drive.

The primary objective of this invention is to increase the strength, accuracy and efficiency of a standard spring-powered air weapon with the help of a suitable additional drive, or double drive, as described below and shown in the drawings.

Other important goals are:

• unlimited power

• constant power

• inexhaustible power

• the ability to regulate and adjust power as needed

• the possibility of compensating the power of the used standard spring

• the possibility of combining different types of drives.

Other possibilities, benefits and advantages of this invention will be evident from the further description of its characteristics and peculiarities.

The pneumatic booster for airguns, according to the present invention, is a special pneumatic actuator designed for a standard spring airgun that converts a standard airgun into a dual-actuated airgun. The aforementioned pneumatic drive device is pressurized and is added outside the compression cylinder to the existing drive with a standard spring, and is engaged and activated at the same time as the drive of the standard spring, and thus these two different drives are combined and transformed into a single driving force that is unlimited, inexhaustible, and can be regulated and adjusted as needed. The air pressure in the pneumatic chamber is constant, does not consume, and can be used to individually fire an unlimited number of projectiles. It can, as necessary, be permanently and indefinitely increased, decreased and regulated.

By increasing the air pressure in the pneumatic chamber, the gradual wear and tear of the standard spring can be compensated for.

This pneumatic actuator, as a booster or dual actuator or as a single or single actuator, is superior to other applicable actuators in airgun manufacturing.

The double drive effect is made possible by a hollow coupling that is connected to the compression cylinder, which physically separates two different drives, but at the same time functionally connects them and adds their power by means of a compression lever-bow that is passed through the cavity of the hollow coupling and the cavity of the standard spring, thus combining the power of the pneumatic piston with the compression piston and turns it together with the power of the standard spring into a single driving force, i.e. a dual-drive air weapon.

The pneumatic amplifier for air weapons, in addition to acting in combination with a standard spring as a double drive, due to the possibility of moving a pneumatic cylinder with a pneumatic piston from a pneumatic chamber to a compression cylinder, can also act independently, without a standard spring, as a single drive.

This type of drive is again made possible by a hollow coupling, but with the help of a short pressure lever, as an independent single drive.

The air gun pneumatic booster combined with a standard spring or on its own allows two different drive types to have four different drive modes in the same air gun:

1. Standard spring independent, single drive

2. Standard spring + pneumatic drive, double drive

3. Pneumatic drive with pressure lever - long, single drive

4. Pneumatic drive with pressure lever - short, single drive

TECHNICAL NOVELTY, SOLUTIONS OR IMPROVEMENTS ENABLED BY A PNEUMATIC AMPLIFIER FOR AIR WEAPONS IN RELATION TO THE EXISTING STATE OF THE ART:

• An airgun airgun, logically, produces more power in an airgun than a standard spring-only drive itself.

• The power of the pneumatic amplifier for air weapons is relatively unlimited, constant, non-consumable and can be regulated as needed; sport shooting or hunting, softer or harder projectiles, lighter or heavier projectiles.

• The air gun amplifier does not weaken when the air gun is cocked for a long time as is the case with a standard spring, which is a convenience in hunting.

• A pneumatic booster combined with a standard spring makes it an airgun, a dual-actuated airgun.

• The pneumatic amplifier for air weapons can also work independently in the function of a single drive.

• With a pneumatic chamber with a larger capacity, the compressed air is more elastic than a standard spring and is more easily clamped for the same drive power compared to a standard spring, or a pneumatic insert - gas ram.

• The pneumatic amplifier for air weapons, when operating independently, especially with a pressure lever-short, due to less mass and a shorter slide path, does not have the recoil produced by a standard spring during the trigger, which has a positive effect on the accuracy during sports shooting.

• The pneumatic power amplifier for airguns, when operating independently, is quieter because it does not produce the vibration that a standard spring does when decocking.

• The pneumatic airgun power amplifier can be mounted on most pre-manufactured existing airgun models with a standard spring.

• The pneumatic amplifier can compensate for the gradual weakening of the power of the standard spring which is consumed by use.

• Pneumatically powered airguns can be produced just as economically as standard spring loaded airguns.

• Air weapons with a pneumatic amplifier or only with a pneumatic piston can be easily adapted to the production of new models of air weapons, with minimal adaptation, without significant modification, of existing models and the basic construction of air weapons, that is, the overall mechanism of air weapons.

• The pneumatic amplifier mechanism for air weapons is not expendable, it can be repaired, that is, serviced and replaced rubber rings that serve as gaskets/seals.

• The pneumatic amplifier for air weapons is pumped with a regular hand pump that is included in the kit, so the power of a particular drive and/or combination is only a matter of choice, according to desire or purpose.

• Using a manometer, the power of the pneumatic drive can be measured and adjusted as needed, by pumping or releasing air from the pneumatic chamber.

Examination of the invention

Testing was conducted with a pneumatic airgun amplifier combined with a standard spring as a double drive and alone without a standard spring as a single drive. A standard air rifle, caliber 4.5 mm, was used, which with a standard spring ejects a lead projectile/diabolo with an initial velocity of 305 m/s.

It is logical that even the slightest additional power will increase the total power of the drive, that is, the strength of the air weapon and the initial velocity of the projectile.

Here, for the sake of safety and certain mechanical limitations, in this procedure and level of testing, an additional approximate load was applied with a pneumatic drive up to +50% to the power of the standard spring. In the absence of a chronometer, the effect was measured by the depth of penetration into wood, paper and paraffin. Results +50%, which should be equivalent to a standard lead projectile/diabolo velocity of 305 x 1.5 = 457 m/s.

Today, the highest known speed of a standard lead projectile, in the magnum versions of air weapons on the market, is up to 380 m/s.

The test of the power of the pneumatic drive itself using the pressure lever-short in the version of the single drive, without a standard spring, was performed with the same air weapon, caliber 4.5 mm, which with a standard spring ejects a standard lead projectile/diabolo with an initial velocity of 305 m/s, and a significantly better result was achieved than the drive of the standard spring itself, which can be better under certain conditions, comparing the penetration into wood, paper and paraffin.

Although it is necessary to carry out further tests and improvements in order to apply and produce various types of air weapons based on this invention as high as possible, it is considered that this and this type of testing of this invention can satisfy the needs of this application. Further tests and improvements of this invention can only further confirm the stated results and even improve them.

The drawings were made in natural size, then reduced together, and thus are proportional in these proportions.

Detailed description of the method of realization of the invention

(in addition to providing an example of execution with a reference to drawings and appropriate terminology)

Figure 1 shows a section of the mechanism of the pneumatic amplifier for air weapons in the function of double drive. It consists of a hollow coupling 1, which by means of screws 8 connects this pneumatic mechanism with a compression cylinder 9, a pneumatic chamber 2 with compressed air 3, a pneumatic cylinder 6 with a pneumatic piston 5, a valve 4 through which air is pumped or discharged, pressure levers-long 7, which passes through the hollow coupling 1 and the cavity of the standard spring 11 to the compression piston 10, thus acting as a double drive. Here, the hollow coupling 1 physically separates the two drives, the drive of the standard spring 11 and the drive of the pneumatic piston 5, but at the same time functionally connects them. These two drives are engaged and disengaged at the same time, so their power is combined into a single drive power, thus creating a new dual-drive air weapon. It is logical that even the smallest power of the pneumatic mechanism, which is added to the standard spring 11, makes this combined drive stronger than the standard spring 11 alone. Taking into account that the air pressure in the pneumatic chamber 2 can be increased relatively indefinitely by pumping, it can be concluded that and the power of this combined powertrain is also relatively unlimited.

This pneumatic assembly, i.e. the Pneumatic Amplifier for Air Weapons, can also operate independently, without the standard spring 11 as a single pneumatic drive.

On Fig. 2 shows a cross-section of the mechanism of a pneumatic amplifier for air weapons in the function of a single drive using compressed air 3, a hollow coupling 1, a pressure lever-short 12, but without a standard spring 11.

In this combination, the pneumatic cylinder 6 and the pneumatic piston 5 are moved from the pneumatic chamber 2 to the compression cylinder 9 and are connected to the hollow coupling 1 on the side facing the compression cylinder 9, and are thus drawn into the compression piston 10, instead of the standard spring 11 which is removed, and thus the pneumatic piston 5, which is under the direct pressure of the compressed air 3 from the pneumatic chamber 2, acts via the short pressure lever 12 directly on the compression piston 10 which creates pressure in the compression cylinder 9 which ejects the projectile/diabolo.

By applying this variant of the drive with a pneumatic piston 5 and a pressure lever-short 12, without the standard spring 11, the problem of vibration and noise produced by the standard spring 11 is also solved, and the smaller mass and shorter slide path have a positive effect on the accuracy in sports shooting.

The connection of this pneumatic chamber with the compression cylinder, in new models of air weapons, can be done differently and in more convenient ways.

The clamping system of the compression piston 10 and the trigger mechanism as well as the compression piston 10 itself and the entire basic structure of the compression cylinder 9 can remain the same with slight adaptation to the new drive.

This pneumatic mechanism is superior, alone or in the above combinations, and is characterized by relatively unlimited drive power, constant and inexhaustible power when acting alone or in combination with a standard spring 11, and provides the ability to fire an unlimited number of projectiles individually, as well as the ability to regulate and adjust the drive strength and power of air weapons.

Method of application of the invention

In this way, this invention enables the creation of a pneumatic amplifier for air weapons as an additional drive, for existing models of air weapons, as well as the creation of new models of air weapons with a pneumatic drive of this type, in several possible variants and combinations, which are stronger, more precise and more efficient. which can be produced economically and thus at the same time includes significant improvements compared to already known devices of this type, i.e. to already known types of air weapons with only a standard steel spring or with already used pneumatic drives of another type.

It will be apparent to those skilled in the art that multiple variations and combinations of dual or single air powered air weapons of this type could be made in accordance with the present invention without departing from the spirit, scope and spirit of the present invention.
