Reference will be made to Figures 1-3, which show a firearm and its lock constructed and functioning in accordance with one preferred embodiment of the disclosed invention. The firearm 20, shown here as an M-16 type rifle, may be any suitable firearm having a magazine well 22 and a magazine opening 23 associated therewith. According to one recommended embodiment of the presented invention, a lock for preventing unauthorized firing from a firearm 20 has been realized, which lock includes a bullet magazine pin 24 that is placed in the bullet magazine 22 and a lock assembly 26 for holding the magazine magazine pin 24 in a locked position in the magazine magazine 22 . According to one recommended embodiment of the presented invention, the lock assembly is placed at least partially inside the opening 23 of the container.

As shown in Figure 3, the lock assembly is substantially surrounded by the opening 23 of the container and almost completely enclosed by it. This construction makes it almost impossible to forcefully separate the lock assembly 26 from the pin 24 of the bullet bed, without at the same time damaging the weapon to the extent that it will prevent its normal use.

As shown in Figure 2, the bullet bed pin 24 includes a longitudinal member 30 and a locking member 32 which extends transversely to the longitudinal member 30. Conveniently, the longitudinal member 30 has a front part 34, and a central part 36, from the lower side of which provides a locking element 32. The locking element 32 is made with a series of annular grooves 38 that facilitate its locking by means of the lock assembly 26. In the embodiment of Figure 2, the locking element 32 comprises only one pin.

It is desirable that the front part 34 has external dimensions that correspond to the dimensions of the bullet for a given weapon, and that the external diameter of the central part 34 forms a support 39 that rests on a corresponding support 40 at the rear end of the magazine 22 of the bullet. It is advantageous for the front end of the front part 34 to be tapered to facilitate its insertion and removal.

According to one recommended embodiment of the presented invention, the lock assembly comprises a lock insert of any suitable type. One particularly suitable type of lock cartridge for this purpose is the Model No. 28273001, which is commercially available from Mul-T-Lock Ltd., Yavne, Israel, and which has a reinforced housing 42 with a single opening 44 to accept a single locking pin. It is desirable that the dimensions of the outer cross-section of the lock assembly be quite close to the dimensions of the inner cross-section of the opening 23 of the container.

Reference will now be made to Figures 4 and 5 which show a lock constructed and functioning in accordance with an alternative embodiment of the present invention. In this embodiment, one locking extension element 50 is placed, comprising a front part 52, a middle part 54 and a retractable rear part 56. The first locking pin 58 extends vertically from the middle part 54, while the second locking pin 60 extends vertically from of the removable last part 56.

In use, upon insertion of the locking element 50 to lock the firearm, the retractable rear portion 56 is pushed all the way forward toward the front portion 52, as shown in broken lines in Figure 4, to allow the forend portion 52 to be inserted into the breech. bullet through the opening of the 23 magazine. When the front part 52 is placed in the bullet seat 22, the retractable rear part is pulled back so that the clearance between the locking pin 58 and 60 corresponds to the clearance on a conventional lock cartridge 62, such as Model No. 28270038, commercially available from Mul-T-Lock Ltd., Yavne, Israel.

Reference will be made to Figures 6 and 7 which show a lock constructed and functioning in accordance with another alternative embodiment of the illustrated embodiment. This embodiment utilizes a retractable locking member 70 having a front portion 72 and a middle portion 74. The first and second locking pins 76 and 78 extend at right angles to the middle portion 74.

In contrast to the embodiment of Figs. 4 and 5, here the first and second locking pins 76 and 78 are relatively close to each other, and the front part 72 is relatively short, so that it allows the insertion of the locking element of Figs. 6 and 7 into the magazine without some special difficulties.

In this case, a lock cartridge 80 is used which has two openings 82 for receiving the locking pin, placed at a close distance from each other.

In accordance with one preferred embodiment of the present invention, each of the lock cartridges according to the present invention may be provided with a lock assembly that automatically locks upon improper handling along its line, which will be described with reference to Figures 8A-12.

Reference will be made to Figures 8A and 8B, which show a key-operated lock 105 constructed and operating in accordance with one preferred embodiment of the disclosed invention. The key-operated lock 105, in the embodiment shown, includes the locking element 50, previously described with the reference from figures 4 and 5, although it is understood that the lock 105 can be easily adapted for the pin 24 of the bullet bed (figures 1-3) and for locking element 70 (Figures 6 and 7).

The key-operated lock 105 includes a housing 110, which typically includes a hardened outer shell 112 and an inner portion 114 positioned within the outer shell 112, as shown in Figures 8A and 9A.

According to one preferred embodiment of the present invention, the lock 105 comprises a separable shackle formed with at least one arm 122. In the embodiment shown, there are two arms 122, both of which are formed with an inwardly directed notch 124, and each of them corresponds to a pin for locking the element for locking, either the version from figures 4 and 5, or the version from figures 6 and 7. Openings 126 are made in the housing 110 for accepting the arms 122 of the shackle 120. Alternatively, the shackle 120 can have only one leg 122, and the housing 110 can be made with with only one opening 126.

The lock 105 contains a locking mechanism 130, which includes first and second locking elements 132 and 134. The locking members 132 and 134 are arranged to slide relative to each other and move away from each other under the action of a spring 136, shown in Figures 8B and 9B. Mechanism 130 optionally engages notches 124 in arms 122 of shackle 120, as shown in Figure 8A.

The locking mechanism 130 is actuated by a cylinder lock 140 which includes a cylinder 142 in which a key slot 141 is formed, into which a key 144 can be inserted, as shown in Figure 8A. The cylinder lock 140 can be quite conventional and is commercially available from Mul-T-Lock Ltd., Yavne, Israel. The cylinder 142 has a plurality of pins 145, which slide relative to the pins 146 of the housing, which is pressed against the springs in the block 148 of the cylinder lock 140, as shown in Figures 8A and 9A. Insertion of the key 144 into the slot 141 aligns the cylinder pins 145 with the housing pins 146 along the line of travel 149, which allows the cylinder 142 to rotate and actuate the locking mechanism 130 of the lock 105, which will now be described.

The locking mechanism 130 is coupled to the two drive outlets 150 and 152 of the cylinder lock 140. By turning the key 144 in the direction of the arrow 160, as shown in Figure 9A, the outlet 150 moves laterally in the direction of the arrow 162, thereby moving the locking element 134 in in the direction of arrow 162, as shown in Figure 9B. Turning the key 144 in the direction of the arrow 160 simultaneously moves the locking outlet 132 in the direction of the arrow 164, opposite to the direction of the arrow 162, thereby pushing the element 132 against the action of the spring 136 in the direction of the arrow 164, as shown in Figure 9B. In the position shown in Figures 9A and 9B, the arms 122 of the fittings 130 can be removed from the opening 126.

According to the previous description, the lock 105 is actuated by a key 144. Unscrupulous individuals can actuate the lock 195 by breaking a portion of the lock 105, for example by tearing along the line of movement 149, which allows the cylinder 149 to rotate freely without using the key 144.

Figures 10-12 will be considered further. according to one recommended embodiment of the presented invention, the lock 105 comprises a locking element 170 which is connected to an actuating device 172. The actuating device comprises a pressure device such as a spring 180, which has a long extension 182. The spring 180 is connected to the locking element 170, while the end 184 of the extension 182 is fixed to the housing 110, as shown in Figure 10. It is recommended that the extension 182 be placed in the groove 186 made in the block 148 along the line 149 of movement, as shown in Figure 12.

Referring to Figures 8A, 9A and 10, it can be seen that a notch 190 is formed on the leg 112 of the shackle 120. The locking element 170 can be pushed into the notch 190, as will be described.

As seen in Figure 10, the actuating device 172 exerts a holding force on the element 170 in the direction of the arrow 192, to prevent the movement of the locking element 170 in the notch 190. When tearing along the line of movement 149, the extension 182 of the spring also tears, thereby the holding force stops and the locking element 170 moves in the direction of the arrow 194 into the engagement with the notch 190, as shown in Figure 11.

It is understood that when the locking member 170 is engaged with the notch 190, the shackle 120 cannot be removed from the housing 110, even if the cylinder 142 were to rotate in an attempt to actuate the locking mechanism 130 and move the members 132 and 134 to locking from engagement with notches 124 fittings 120.
