Abstract

This invention is subject to a locking system preventing the repression of the security latch that changes the position of the gun into 'security' or 'firing' into the 'firing' position and locks it during the position 'security'. A locking cylinder (3), which is placed into the cylinder gap (12) formed directly in the trigger block on which the parts which constitute the trigger and security system of the gun, prevents the setting of the security latch (4) from 'security' into 'firing' position, pushing the locking pin (4) so that it forms a prevention in front of the echelon (53) in the locking pin through a locking pin channel (31) formed on its side surface in case it is turned in this gap through its special key. Furthermore, the replacement of the locking cylinder (3) upon any possible action from outside has been prevented through a secret pin (6), placed into a blind pin gap formed against another channel (32) created on the side surface of the locking cylinder (3) and whose one end is operating in the said channel (32).

Description

DEFINITION Locking System of Security Latch for Fireguns

a- Related Field of Inventon

This invention is related to a locking system that prevents fireguns to be used by unauthorized people when locked with a special key except its owner and enables its use after the lock being opened.

Considering the fact that the misuse of fireguns or their use by unauthorized, careless, absent - minded or forgetful people, children or worse, evil intended people can lead to very bad results, the security systems of fireguns have been paid special significance.

The following three main systems have been used in regard to this subject; 1- Trigger Protection

The trigger, having the initial active role by the usage of the gun, should be protected against any outside impact. Therefore, a protective ring has been formed around the trigger. This ring is a kind of protection that enables the entrance of the finger if the user wishes to pull the trigger and prevents other impacts as far as possible.

2- Security Latch

This is a system having two positions developed for the prevention of the trigger motion and thus, the firing in case of any incidential, sudden pressure to the trigger as a reflex or as a result of forgetfulness. If the latch is positioned to "security", the gun does not fire even if any pressure to the trigger has been made. security latch. In order to prevent this, a bevel no. 51 has been located to the end of the security latch and pushed to the opposite side. Through the said methods, the activity of the gun has been blocked and a full security has been provided. Further advantages of the secret pin channel and the pin relation are preventing the downfall of the lock cylinder, its up - down motion in the cylinder gap, providing an rotating ability for only 90° and an easy finding of the open - locked positions of the cylinder. The four channels in the cylinder gap enables the lock cylinder to be taken over the gun during its "open" position and this ensures an easy use.

Consequently, besides the protective function of the locking system, there are many other advantages such as an auto-security formation of the locking system, fitting in smaller volumes, adaptability to many kinds of guns, simplicity and ease of manufacture, having no affection to the operating system of the weapon and its look, etc.

5,081,779 USA Patent

5,645,519 USA Patent The disadvantages of the USA Patent no. 3,553,877 being similar to the invention are;

1- The lock system in this work has no design and a locking system, normally used for the locking of furniture drawers, has been used. There is no security for the unmount of the lock from the gun. la- As applied in the example, the lock system will not be able to protect the security of the gun since it is also unable to protect its own security, because the lock can be unmounted. The part can be mounted to the gun without lock and the gun can be activated. lb- The bolt system is highly rough and it has to work at the upper part of the lock. For this reason, the usage of this type of lock for a gun other than the one displayed can only be possible through a special design that will fit the lock. This is not logical. lc- Screw type connection to the wooden part is insecure and has no aesthetic. EXPLANATIONS OF THE FIGURES

OPERATING SYSTEM

A gun has been provided in order to show the application of the invention. The trigger block (1) and the parts of this gun, regarding our subject, have been shown in fig. 1. These parts consist of the centering pin (22), which shall constitute a center for the rotating motion of the trigger (2), and the trigger block (1), a security part (17) on the trigger block

(1) to provide a proection against eventual outside impacts, security latch

(5), security end (21) which was formed in order to prevent the motion of the trigger (2) by means of an integration to the latch (5) while it is under "secure" position even if the trigger is pulled, a pressure pin (24) that applies a certain pressure to the security latch through the power it receives from the pressure spring (25) to provide the replacement in case of a pressure, a stationering pin (26) formed for the prevention of the backslipping of the pressure spring (25) and the hole no. 11, perforated on the trigger block (1) for positioning these pressure parts.

Other parts regarding the mounting template and which are not related to the invention, have not been demonstrated. However, the bed (10) and the body of the gun (9) have been partially shown together with the mounting concept in order to give an idea about the location form of the trigger block (1) in the weapon.

Figure 2 shows the renewals undertaken for the trigger block (1) in regard to the invention. The end part (1) of the trigger block has been enlarged and the hole no. 11, in which the pressure group shall be positioned, has been replaced. In the volume, that was formed, the cylinder gap (12) and 4 cylinder claws (16) around it have been formed with a distance of 90° each. (The view of this part from the top has been demonstrated as cross section in fig. 9 and 11.) Furthermore, two additional holes have been perforated, whose functions will be discussed later. These consist of a blind opened secret pin hole (13) and a locking pin hole (14) that has been opened in order to explode to the security latch (5). Additionally, the parts shown under fig. 5 have also been designed for the invention. These consist of a secret pin (6), secret pin spring (7), locking pin (4), locking pin spring (8), security latch on which the bevel no. 51 has been added (5), special key for locking and opening of the lock (38) and the locking cylinder, whose detailed drawings are available under fig. 12, 13, 14, 1 and 16. On this locking cylinder (3), a top view figure, locking pin channel

(31) demonstrated under fig. 14 and 15 as cross section and a secret pin channel

(32) have been constituted with two special formed channels. Further, a bevel no. 33 has been located on the end part of the locking cylinder to ensure an easy mounting process.

Another subject regarding the lock cylinder, which should be paid attention to is, the claw gap (35). These gaps are the well known cases of the technique and therefore, they have not been fully stipulated until now. As known, these types of locking cylinders (3) can either have pins or claws as in our example. The subject has been tried to be explained in our drawings under fig. 12, 13 and 16. In such locking cylinders (3), claws (40) being pushed outwards by the springs (41) positioned in the claw gaps (35) (these are generally four pieces) are available.

These claws (40), adjusted in order to arrive the same range, shall give effort to exit by the pushing of the spring no. 41 when the special key is pulled out. These claws, trying to get out when the special key is positioned inside, get into the claw gaps (16) in the cylinder gap (12). Under this condition, the locking cylinder is unable to rotate in the gap and locking occurs. When the special key (38) is used, tthe locking cylinder (3) can rotate in the cylinder gap due to the achievement of the same range with the external diameter of the locking cylinder (3).

The claw gaps (35), which should be located on the locking cylinder (3), have been positioned in the middle part of the locking cylinder in order to constitute the locking pin channel (31), being one of the necessary channels for the invention (fig. 12, 13). And now to the mounting and operating means of all alterations and parts regarding the invention;

The modification made by the trigger block (1) and the mounted status of the related parts to the trigger block (1) have been shown in fig. 3. Here, a cross section has been taken for a sufficient explanation of the operating means of the pressure equipment as well as the security latch (5).

As shown in fig. 4, the pressure pin, being pushed downwards by the pressure spring (25) that leans against the stationering pin (26) is located into one of the station channels (52) with radius and formed on the security latch (5). The security latch in this case (5) will not replace its position unless a pressure in a certain power is applied. However, a pushing power to be applied on the security latch shall defeat the power of the pressure pin (24) and will be able to move ahead.

In this case, the pressure pin that quits from a station channel will be positioned into another channel, which shall result in the second position of the security latch (5). Due to the radius structure of the station channel and pressure pin ends, the security latch will not be able to stay in any middle position. This template assures both for the security latch, changing its position without any pressure and its location except these two positions defined.

The location of the parts shown in fig. 3 are as follows: The locking pin spring (8) and locking pin (13) have been placed into the locking pin hole demonstrated in fig. 2, whereas the secret pin spring (7) and the secret pin (6) were positioned into the secret pin hole. The locking cylinder on which a position no. 33 has been formed, was located into the locking cylinder gap (12) shown in fig. 2, in order to ensure an easy mounting process.

In this stage, the secret pin (6) and the locking pin (4), being pushed by the springs placed at their behind, are being placed into the locking pin channel (31) and the secret pin channel (32) for their passage.

The secret pin (6), under the pressure of the spring (7), that has been located into the secret pin channel shown as an upper cross section in fig. 14, will prevent the up - down motion of the locking cylinder (3) in the gap and its unmount from the trigger block (1) since the secret pin (6) will not be reached following the montage and a pressure will not occur. Furthermore, another advantage of the secret pin (6) and the channel (32) combination is, that it restricts the rotation of the locking cylinder (3) in the cylinder gap (12) in certain intervals. In our example, the lock cylinder (3) is able to rotate 90°. The secret pin channel (32) has an appropriate form for this rotation ability.

The fig. 8, 9, 10 and 11 show the front and upper cross sections of the part of the trigger block (1) regarding the invention, whose mounting is displayed in fig. 3, explaining the locking process. The system operation can be clearly understood via these figures.

As we formerly explained through fig. 4, we can see the security latch

(5) which can move only by a certain pressure, in the "firing" position in fig. 8 and 9. The small diameter part of the latch (5) has the same range with the channel (2) in which the trigger moves. In this case, the security latch (5) does not constitute a prevention in front of the end no. 21 of the trigger (2). Since the end no. 21 will not be attached to the security latch (5) through the pressure on the trigger (2), the trigger will be able to move and the gun will be fired.

The figures 10 and 11 show the pushed position of the security latch (5) to the "security" position. In this case, the big diameter part on the security latch (5) will constitute a prevention in front of the end no. 21 of the trigger (2). Even if the trigger is pulled, it will not be able to move because the end no. 21 shall block the security latch (5) and prevent the gun to be "fired".

If firing is desired, the security latch (5) can be pushed towards the

"firing" position. The invention, that was designed in order to prevent the firing procedure by indesired people and aiming to block the "firing" position of the gun by means of locking the security latch, operates as follows:

First of all, the security latch (5) is set to the security position as shown in figures 10 and 11. The special key (38) is attached to the locking cylinder (3). The claws (40), formerly explained together with the figures 13 and 16, are pushed inside of the claw channels (35) in which they move and their ends are set to the same level with the external diameter of the locking cylinder (3). In this case, the claws (40) won't prevent the rotation of the locking cylinder (3) in the cylinder gap (12). The claws are not shown in other figures.

During this process, the locking cylinder (3) shown in figures 8 and 9 will rotate 90° with the aid of the special key (38) within position shown in fig. 8 and 9, it will obtain the position in figures 10 and 11. The locking pin channel no. 31, having a special formon the locking cylinder (3) will push the locking pin (4) towards the security latch (5) defeating the power of the locking pin spring (8). As shown in figure 11 the locking pin (4) located in front of the part on the security latch (5), will prevent this latch's pushing process towards the "fireable" position. In this case, if the special key (38) under the pressure of the spring no. 41 is taken out, the ends of the claws (40) will reach the claw gaps (16) opened in conformity with the "locked" position of the locking cylinder (3). The gun will be locked and indesired people won't be able to use it. The setting of the gun for use is possible only when the lock is open.

This means that the special key (38) shall be put into the lock cylinder (3) and turned to the opposite side as shown in figures 8 and 9. In case of the locking cylinder (3) is positioned "open", the locking pin (4) being pushed by its spring (8) will recede from the latch (5) and will not constitute a prevention in its front, ensuring an independent operation.

Following the opening of the lock cylinder (3), the key (38) should be taken out. Since the security latch (5) of the gun is able to operate freely in this position, it can be positioned for "security" or "fire" if desired.

In order to ensure a complete security against the use of the gun by indesired people, the unmountability of the locking and security systems from the gun should be assured. Otherwise, these elements will be unmounted from the gun and the usage will be enabled. The prevention of such unmounting has been assured by the aid of the secret pin (6) and its channel (32). The secret pin gap (13), that consists of a blind hole, will ensure this by means of a pressure on the secret pin will not be possible once the spring (7) is placed into this hole and passes through the secret pin channel (32) on the locking cylinder (3). Getting out of the locking cylinder will be impossible.

Another duty of the secret pin (6) and its channel (32) is to allow the rotation of the locking cylinder (3) only by certain angle intervals. So, the "open" and "locked" positions can be easily found and the up - down motions of the locking cylinder (3) within the cylinder gap (12) will be prevented.

The security latch (5) can be moved more forward towards the "security" position and taken completely out from the trigger block(l) in order to block the security system. In order to prevent this, a bevel no. 51 has been constituted on the end part of the latch (5). As it can be seen in fig. 11, it is impossible to get out the security latch (5) by pushing it to any direction while the gun is locked. As formerly explained, the locking pin (4) will prevent the "firing" position of the security latch (5). The bevel no. 51 will then prevent the pushing process of the security latch (5). The gun in this position will completely be under control of its owner. INDUSTRIAL APPLICATION

The trigger block of the guns given as examples, are formed with the plastic or metal injection methods. Therefore, the locking type being used in the example, is a type that has claws in the locking cylinder, since the cylinder gap is confomable to the formation with the injection method and is more easy.

If the gun part in which the locking cylinder shall be placed into is being manufactured through the sawdust method, the locking cylinder type bearing pins inside should be preferred. The formation of the cylinder gaps of such locks during the production stage is more easy.

Different from the locking systems with pin and claws able to be locked or opened with the special key of the invention, a coded lock, to be placed Into the trigger block may also be used . The functions of the parts contained in such locks can operate as the locking pin (4) described under the preferred arrangement of the invention.

The locking system described under this definition ensures the direct control of the trigger and cock in addition to the control of the security latch (5) of a firing gun. In such a case, the locking pin (4) shall be used for forming a blockage in front of an appropriate jut on the cock or trigger.

The elements, that constitute the locking pin subject to this invention, have been named and figured in accordance with the preferred layout of the invention in order to ensure an easy understanding of the requests and have no restrictive effect as figure, application or naming on the are of the said elements.
