Description

METHOD AND DISPOSITION RELATED TO A WEAPON WITH A CLOSURE BLOCK DESCRIPTION OF THE INVENTION The present invention relates to an arrangement and a method that relate to a weapon equipped with a locking block so that the weapon can not be used in the case of unauthorized appropriation. An object of the present invention is to provide an arrangement and a method by which a weapon will be destroyed along with the unauthorized handling of the weapon. This object is achieved with the arrangement and the method having the characteristic aspects established in the claims. The arrangement of the invention helps to make the thief of such weapno longer of interest, by virtue of the fact that the weapon will be damaged to such an extent that the repair of the weapon becomes extremely difficult and complicated. The arrangement can be combined with many different types of alarm systems and devices, which generate an alarm signal that activates the arrangement of the invention in order to destroy the weapon. The provision of the invention presents both technical and economic advantages. The invention will now be described in more detail by making - -li, • *, i t i w. ¿. reference to its illustrative embodiments and also referring to the accompanying drawings, in which: Figure 1 is a schematic illustration of a weapon provided with an arrangement of the invention; Figure 2 is a schematic illustration of the arrangement on a larger scale; and Figure 3 is a schematic exploded view of said arrangement. The arrangement 1 of the invention includes an expansion mechanism 10, which is designed to be fixed to a front portion of a so-called lock block housing 101 of a weapon 100. the expansion mechanism 10 has a front sleeve portion 11 , which is designed to be tightly fixed in the chamber 102 of the weapon. The expansion mechanism 10 also includes a rear sleeve 12 having a cavity 13, which communicates with a cavity 14 in the front sleeve 11. The front sleeve 11 has a front opening 15 and the rear sleeve 12 has a rear opening 16. The rear end of the sleeve 12 includes a radial hole 17 for adapting a so-called detonator or fulminating capsule 30. The rear sleeve 12 carries a guide pin 18 externally disposed, which forces the expansion mechanism 10 to its correct rotation position. when said expansion mechanism is placed in its intended location in the closing block housing 101 of the weapon. The guide pin 18 is guided by the reservoir support 103 of the weapon and also functias a handle when inserted - ,, *? K * tm? * & "Te * tkJ &Ít? Fat" i * the expansion mechanism 10 on the weapon and when said expansion mechanism 10 is removed from it.The expansion mechanism 10 also includes an end plug 20, which is screwed into the rear part of the sleeve 12. The end plug 20 has an external thread 21, which coincides with an internal thread 19 on the sleeve 12. The end plug 20 has a square screw head 22, through which the plug 20 it can be screwed firmly into the sleeve 12. The end plug 20 also includes an air passage 23 for communication between the hole 17 and the cavity / space 13 in said sleeve 12, and to adapt to the detonator 30. When required, the air passage 23 is filled with explosive, in order to ensure that a fully effective explosion will occur.The arrangement of the invention 1 also includes a so-called discharge tube 40, which is configured and dimensioned. The discharge tube 40 has an internal, rear cavity 41 and a front internal cavity 42, which respectively are filled with a substance to be fixed in the barrel 104 of the weapon 100, as is evident from Figures 1 and 2. explosive or device 43, 44, such as pentyl or the like. Disposed within the tube 40 is, for example, a pentyl bait 45, which establishes communication between the two explosive substances or devices 43 and 44. The front end of the tube 40 includes an internal thread 46, which receives an external thread 52 on the rear end 51 of a fixing pin 50, thereby allowing the pin to be screwed into the tube 40. the length of the pin 50 is such that said pin will project beyond the muzzle of the barrel 104 when the arrangement of the invention is mounted on the weapon 100, thereby enabling the front end 53 of the pin 50 is anchored in a desired way in relation to the weapon and / or its surrounding parts. The arrangement of the invention 1 also includes a knock or trip pin arrangement 60 that includes a trip pin 61, which is held in a backward / inactive position through a compression spring 62. The pin arrangement of shot 60 includes an electrically activated explosive charge 63, which is communicated, via an electric ignition wire 64, with a firing device 70, which is adapted to supply an electrical signal that activates the explosive charge 63 when necessary , thereby driving the firing pin 61 against the detonator 30 and thereby causing the detonator 30 to fire the explosive charges / explosive devices 43-45. The trigger pin arrangement 60 and the detonator means 70 are preferably incorporated in a simulated tank 80, in order to minimize the possibilities of manipulating the arrangement. The triggering device 70 will normally receive its activation signal through the means of an alarm circuit 90 provided, for example, in a protective housing in the form of a cover & ßt * Í, «. of weapon (not shown) or similar. The fixing pin 50 may include a pivoting means 54, which allows the pin to be pivotally mounted on the cover of the weapon or bag, and the simulated tank 80 can be firmly anchored within the cover or bag. The arrangement of the invention 1 is fixed to a weapon 100 in the following manner. The detonator 30 is attached to the expansion mechanism 10, which includes the sleeves 11 and 12 and the end plug 20 screwed into the rear part of the sleeve 12. The expansion mechanism 10 and the detonator 30 attached thereto are then placed in the closure block case 101. The closure block 105 then abuts the screw head 22 in order to keep the expansion mechanism 10 in place, where with the sleeve 11 it is guided towards the chamber 102 of the weapon. The discharge tube 40 is then inserted into the barrel 104 of the weapon, with the help of the fixing pin 50 screwed to the discharge tube 40, so that the explosive charge 43 will be located within the internal space 13 of the expansion mechanism 10 and thus the explosive charge 44 will be placed in the barrel 104 of the weapon. The simulated tank 80, with the firing pin arrangement 60 and the detonator 70 attached thereto, is then attached to the weapon 100, with the firing pin 61 located near the detonator 30. The detonator arrangement 70 is then connected to a 90 alarm circuit suitable. Figures 1 and 2 illustrate the arrangement 1 of the invention placed in a weapon 100. When an alarm is activated in response, for example, in an attempt to steal the weapon, the alarm circuit 90 will activate the detonator arrangement 70 in a manner that an electrical signal will be produced and activate the explosive charge 63 to drive the firing pin 61 against the detonator 30, which, in turn, fires the explosive charges / explosive devices 43-45. The forces generated by the explosive charge 43 deform the expansion mechanism 10 and destroy the closure block housing 101 and those parts of the weapon that surround the locking block, while the forces generated by the explosive charge 44 deform the barrel 104, with this making the weapon 100 useless. When a weapon, which has presented the alarm according to the invention, is removed by an authorized person, the alarm is first deactivated and the weapon is then separated from the simulated tank 80 before removing the fixing pin 50 and its tube. connected discharge 40 of the weapon. The expansion mechanism 10 and its connected detonator or fulminating capsule 30 are then removed from the weapon, so that after the closing block 105 can again take its final position forward. It will be noted that the arrangement 1 of the invention is very safe to handle, since the component parts of the arrangement are safely separated with respect to accidents, since the simulated tank 80 and the firing arrangement 70 and the pin arrangement trigger 60 connected to the simulated tank are first removed from the weapon before dismantling other component parts. The firing arrangement 70 is well protected within the simulated tank 80. Unauthorized attempts to deactivate the alarm, for example by firing the arrangement of the invention into pieces, will also result in the destruction of the weapon. In a simplified embodiment, the explosive charge 44 and the pentyl bait 45 can be omitted and only the explosive charge 43 in the expansion mechanism 10 will be retained. In this case, the discharge tube 40 and the fixing pin 50 can be Excluded if desired, and the explosive charge 43 placed directly within the space 13 of the expansion mechanism 10 and the opening 15 sealed. In the case of the simplified mode, the forces generated by the explosive charge 43 will mainly deform the front part of the closure block housing 101. The chamber 102 and the rear of the barrel 104 will also deform to some degree. In a further simplified embodiment of the invention, the detonator or fulminating capsule 30, firing pin arrangement 60 and detonator arrangement 70 can be excluded and replaced by an electric detonator mounted directly on passage 23, in which case the loop alarm 90 is connected to the aforementioned electric firing device. Although not shown, the air passage 23 may include a branch in the form of a small subsidiary passage, which opens adjacent to the trip pin in the closure block. This ,: A1. «> Ifcit, ... will channel a portion of the explosive force in the expansion mechanism 10 to the closure block 105 in order to damage or destroy it. The damage to the closing block can be amplified, mounted in the subsidiary passage, a hard metal pin or the like which is capable of penetrating the closing block. The subsidiary passage can also be provided with a separate explosive charge, in order to further ensure the destruction of the closure block. The expansion mechanism 10 and the discharge tube 40 are conveniently made of steel or other suitable metal, of way that the surrounding parts of the weapon will be primed together in the explosion. Of course, various types of explosive can be used in conjunction with the present invention. It will be understood that the design of the arrangement of the invention can be varied within wide limits, for example, replacing the described components with functionally equivalent components. It will also be understood that the invention is not restricted to the embodiments described and illustrated, and that changes and modifications may be made within the scope of the following claims. twenty
