2. Description
2.1 Title

with cartridge loading, electromechanical shot release and gas-tight, self-locking closure system for safe and rapid firing.

2.2 State of the art

The classification of both the stand-alone and the cannon cannon can be divided into the following main aspects:

2.2.1 Front loading system

2.2.1.1 with attachable or screwable ignition lock, firing pin and primer cap

2.2.1.2 with electric set igniter (set trigger / bridge igniter "A")

2.2.2 Breech loading system

with cartridge operation and purely mechanical firing pin ignition

2.2.2.1 Manually cocking the firing pin and locking it using a pin or safety pin

2.2.2.2 Manually cocking the firing pin and locking it using a wedge or spring bolt

2.2.2.3 Self-tensioning trigger unit of various designs (tensioning, locking and release is done via the trigger cord or chain), which will not be discussed in detail here.

At this point, it should not go unmentioned that all firecrackers - and not only in Bavaria -

Fire or solder iron ignition (laying cannon) Match ignition

Ignition with fuse or ignition wire bayonet closures

are no longer permitted . In this context, reference is made to the "Handbook for Cannon Shooters", a guide from the Trade Inspectorate (6th revised edition, as of February 1991), published by the Bavarian State Ministry for Labor, Family and Social Affairs in cooperation with the Trade Inspectorates of Munich City and Nuremberg (RB No. 10/91/04).

The main disadvantage of firecrackers belonging to main group 2"2 _O 1 is the handling of open black powder (grain size 2.0 mm = firecracker powder), which has to be filled through the ejection openings (muzzle) of the vertically or more or less obliquely upwards fixed or movable tubes.

In this context , unnoticed smoldering residues in the barrel can trigger an unintentional ignition with fatal consequences during the reloading process (powder filling of the combustion chambers) (pressure up to 800 bar at a combustion temperature of approx. 2,500° C).

The consequences of accidental overloading or over-insulation are no less serious. In this regard, it should be noted that in Saarland, the damming of stationary firecrackers (including firecracker cannons) is prohibited. In the general interest of safety, the firecrackers in question should

In general, a dam can be dispensed with, especially since when using the usual amounts of powder (firing charge for a standing cannon = max. 400 grams and for a muzzle-loading cannon firecracker = max. 600 gr ₀ ) the additional dam no longer noticeably influences the volume of the explosion bang (only the bang frequency!).

Further dangers exist when using these firecrackers in stormy weather or when it is raining . Spilled or blown black powder can be ignited by the pressure waves when the shot is fired, as it is "explosive in mass ^" . Wet powder leads to ignition delays (or failures), the duration or ignition process of which can no longer be determined; the same applies to wet equipment,

The elimination of ignition failures is extremely problematic with safety risks that are difficult to assess:

- Checking the ignition system

(2&ogr;2. 1.1 and 2.2.1”2), possible removal of the same

- Check the ignition channel and clean if necessary

- Prepare for repeat ignition

- if you fail again =

completely clear (!) and clean thoroughly

Given the amount of time involved, the fireworks program planned for the celebratory occasion would also have to be considered prematurely terminated on that day; not to mention a possible accident.

- 10 -

The firecracker systems already described (main group 2.2.1 and 2.2.2) pose further risks see here just a few examples:

Due to the height (approx. 50 cm) and the arrangement of the tubes, it is not always possible to avoid accidentally bending or reaching over the launch tubes during loading or when defusing malfunctions. To make matters worse, the gunner and possibly his or her assistants must always be in the immediate area of effect of the tube muzzles when working on the gunner. This proves the need to cordon off the danger area (firing range) over a large area for all bystanders (spectators, etc.).

Example documentation:

- 1936 ..o Sirius safety salute device

(Height = approx. 28.5 cm)

- 1986 .0« Cartridge stand firecracker

with swivel tube (height = approx. 63.5 cm)

- 1988 .”. Sirox cartridge tipping firecracker

(Height = approx. 49.5 cm)

- 11 -

- 11 -

For small firecrackers, the safety area referred to is at least 15 m in radius

see manual for cannon shooters page 43!

and

for cannon fire, at least 30 m in the direction of fire and at least 10 m in the radius around the gun

see manual for cannon shooters page 32!

If standing firecrackers with tiltable, swivelling or inclined tubes are used, a minimum safety zone of 30 m and not, as is usual, only 15 m would have to be maintained in the direction of the tube or the direction of tilting _or swivelling, purely for safety reasons.

- 12 -

- 12 -

Another danger is the accidental discharge of a shot

- by pre-tensioning the trigger mechanism, when cocking or when re-cocking for a repeat firing in the event of an ignition failure

- when closing or locking the bolt, bolt head or tubes, etc.

- when attaching the lanyard/chain or when handling it in any other way

- by accidentally getting caught or stepping on the lanyard/chain

- when setting the primer

- due to weakened or broken springs in the trigger, safety or locking unit

- as a result of contamination, wear or damage to the trigger, safety mechanism, cocking notches, locking or locking units Uo a&ogr;m„

- in the case of delayed ignition, which can have various causes (further explanation is not necessary)

- by explosive or projectile items

- if the safety distance is not maintained (for whatever reason)

- 13 -

The elaborations on the topic of "Description of the technical status" are, as already stated, only examples and therefore not exhaustive. Complete and detailed records would significantly exceed the scope of section 2.2 without making it significantly clearer.

All in all, the objective observer of all these sober facts will have to conclude and conclude that, without wishing to offend their inventors , the devices known to date can no longer claim to be considered up-to-date purely for safety reasons, measured against the current state of technology and in view of the future-oriented development in our society.

2.3 Issues

Reduction of avoidable risks (endangerment of self and others) as far as technically possible.

2.4 Tasks

2.4.1 Cannon shooting as a way of preserving old customs is also becoming increasingly popular in Saarland. The invention is intended to sensitize the population, traditional and other clubs, organizers of all kinds, and the police authorities concerned to the ancient tradition of cannon shooting (on certain celebratory occasions) in order to win new friends and enthusiastic followers of this custom.

To ensure that the joy and enthusiasm of saluting remains unclouded, SAFETY must always be the top priority,

Taking this into account, as well as the densely populated landscape structure of the small Saarland (without "mountains" and large open spaces), it is necessary to set up the shooting range (firecracker location) in the immediate vicinity, almost "in front of the eyes", of those involved, and to objectively improve the requirements for the safety of the shooting operation and to modify the relevant measures accordingly.

- 15 -

- 15 -

2&ogr;4.2 Both the known and the theoretically possible accidents in the use of salute cannons (cannon firecrackers) and stationary firecrackers should be analysed strictly scientifically according to the technical malfunction criteria, including the cases and the possibilities of unintentional operating errors as a result of carelessness or negligence up to and including intent, in order to achieve and guarantee optimum safety.

2.5 Solution

The "problem" is solved with particular consideration of the task with the features listed in the protection claims i _o Vm _o the enumeration of section 2„7

2.6 Summary

2.6.1 The particular problem and its solution requires above all a departure from the conservative forms of firecrackers of smaller design, which in turn places increased demands on transport.

2.6.2 Despite all efforts, it was not possible to exclude all intentional operating errors with absolute certainty; however, they were reduced.

At this point, however, we would like to express the hope that salute devices, regardless of their design, are only used for their intended purpose and only operated by trained and licensed specialists.

- 16 -

- 16 -

Humanity was intelligent enough to develop devices to express joy, now it will have to learn to use them responsibly.

2.7 Advantages and design

2.7o1 Achieved benefits

The advantages achieved with the invention are, for the sake of simplicity, summarized as follows, since they are understandable in connection with the statements on 1", 2.2), 2", 7o2) and 2", 8):

2.7.1«01 Renunciation of condemnation

(only light template)

2.7.1.02 by using the resonance effect of the barrel, the reduction in the amount of powder also inevitably reduces the risk when transporting the explosives to the firing range

2.701.03 no handling of open powder during normal shooting operations

2.7.1.04 no delayed ignition or failure due to a contaminated, unfilled or insufficiently filled ignition channel

2o7.1o05 Avoidance of electrical sparking in the area of the bolt head by using a magnetic valve in the trigger mechanism

- 17 -

- 17 -

2„7ü1.06 Ignition mechanism only for the moment of ignition under power

2o7o1.07 multiple electrical fuses (interruption of the ignition contact line)

2.7.1»08 no recoil-related throwing back or rolling back of the device when firing; therefore and in view of the length and firing position of the barrel, a large-scale cordoning off of the shooting range is no longer necessary, and the safety zone for shooters and helpers can also be reduced

2.701.09 Unloading the device (removal of a failed ignition device) and dismantling the failed cartridge is much easier, faster and, above all, safer

2.7.1.10 the rapid firing sequence makes the costly multi-barrel systems superfluous

2.7.2 Further development

The special feature of the invention lies in the combination of uncompromising safety, weather independence, cartridge operation and rapid firing sequence”

The system presented allows even inexperienced people to easily fire at a rate of 1000 shots per minute. Our cannon team works (easily) with a rate of 6 shots per minute; the maximum training result in one minute is 12 shots. In the interest of safety, however, a cannon program of more than 6 SoPoM should be avoided.

Furthermore, convenient transport is combined with a short assembly time .

The carriage consists of a roadworthy, sprung axle body with pneumatic tires with superstructure, towing, coupling and lighting equipment as well as four support devices &ogr; It can also be designed in other ways, depending on your imagination.

The insensitive trigger unit works with a magnetic valve and a freely moving firing pin (flying pin) and is housed in the bolt head (screwed in).

When the trigger is pressed, the magnetic valve is activated by applying an electrical voltage. The inductive magnetic field attracts the soft iron core, which is in a resting position. This first overcomes a small gap and then hits the firing pin. By releasing the kinetic energy of the core and overcoming the firing pin's ability to remain stationary, the latter is set in motion and in turn hits the cartridge's igniter.

The magnet coil core is brought into the rest position by its own weight after the ignition circuit is interrupted (spring support is not required but certainly possible). Mechanical pre-tensioning is neither necessary nor possible.

Due to the low weight of the firing pin, it is recommended that it be returned to its rest position after the shot has been fired, assisted by spring force; this is also the starting position for a new firing process.

- 19 -

- 19 -

In this position, the firing pin is slightly retracted (even when the solenoid valve is permanently activated) so that the firing pin tip is not damaged when the cartridge chamber moves and accidental ignition is effectively prevented by the cartridge hitting the tip of the pin. As with the solenoid valve, mechanical pre-tensioning of the firing pin is no longer possible and is also no longer necessary.

The locking system consists of the locking housing and the locking block (cartridge storage) that can be pulled out from the front. It is a bolt-block lock with a robust and compact design. It is easy, quick and safe to use and is also characterized by its insensitivity to faults and its ease of maintenance and cleaning.

If the bolt block is not inserted or not properly inserted or not locked, an electrical safety contact prevents the shot from being fired.

The barrel is vertically upwards. It is mounted outside its center of gravity, so that the barrel forces itself into a vertical position due to the weight distribution. A safety stop with locking system prevents it from pivoting or tipping during shooting. If the barrel is not locked or is not locked properly, an electrical safety contact prevents the shot from being fired.

- 20 -

For transport, all main components (barrel, bolt housing, bolt block and bolt head) are housed in a suitable transport container; they can be assembled in a few simple steps using standard on-board equipment. It is also possible to assemble the rifle at home and transport it assembled or partially assembled.

In addition, by separating the main components , it is possible to clean them more easily and thoroughly from corrosive combustion residues.

In rainy weather, it is possible to completely cover the entire gun carriage work or operating area in just a few easy steps.

It goes without saying, but it should not go unmentioned at this point that a caliber was chosen in which

within the meaning of Section 2 Paragraph 1 No. 1 WaffG (case with charge and projectile)

is mass-produced or factory-made and it is not possible for hand-loaders and reloaders to assemble prefabricated loading components into corresponding (live) cartridges.
