Description

The invention relates to a hunting weapon, the

  movable cylinder head has a clamping slide for the rear

  of a striker spring, a pivoting clamping arm

  cooperating with the clamping slide and with the spring-

  striker and a retaining lock cooperating with the clamping slide, the clamping slide being able to adopt a disarming position and an arming position - ready to fire - and means which can be electrically actuated being provided for disarming

  of the striker spring without first firing a shot.

  Document DE-A-44 13 685, among others, discloses a weapon of this type. On the latter, the electrically actuated means provided for disarming the striker spring, and a solenoid housed in the rear stock, which can be electronically controlled, act, directly by means of a connecting rod, on the weight

  oscillating from an impact protection device.

  Apart from the more expensive shaping of the stock for the housing of the electrical device and the batteries and for the realization of the rod leading to the movable cylinder head, the mechanical coupling between the solenoid and the oscillating weight mounted in the movable cylinder head requires a work of considerable mounting and adjustment. The forces proportional to the mass generated by the shots are also considerable. Another disadvantage lies in the size of the solenoid and the batteries, determined by the power and trajectory relationships, and therefore also in

their weight.

  The object of the invention is to improve the device for disarming the weapon mentioned above in such a way that the electrical components can be made as small and as light as possible and that the device can be mounted from the

simplest way.

  According to the invention, this object is achieved thanks to the fact that an interlocking element actuated by an electromagnet is provided, as well as a telescopic slide, one end of which is applied against the clamping arm or the clamping slide and the l the other end has a surface cooperating with a latch for engaging the latching element, and which is in active connection, after latching, with the retaining latch. When the clamping slide is armed, the telescopic slide is armed at the same time and engaged with the locking element. The telescopic slide spring acts here as an energy accumulator, which does most of the work necessary for disarming. The electrical energy (batteries) and the work (solenoid) necessary for its disarming are reduced by this accumulated energy. Due to the minimization of the trajectory and of the force, it suffices for the engagement of the telescopic slide of a mini-magnet (electromagnet)

  which can be accommodated in the movable cylinder head itself.

  In an improvement of the invention, the active connection between the telescopic slide and the

  holding lock is achieved by a disarm lever

  ment pivotally mounted near the retaining lock and the free end of which has an abutment surface on which the other end of the slide

  telescopic abuts after engagement.

  This improvement relates to weapons on which the clamping slide is held by a

  holding latch, which, for disarming, is released

  rusted manually by continuing to push the clamping slide forward. This also remains possible during assembly of the device according to the invention. The magnet can then be placed under the holding latch, where sufficient space is available in the casing of the movable yoke. This arrangement is particularly advantageous when the disarming lever supports the

  oscillating weight of an impact protection device.

  In a preferred embodiment, the latching member is pivotally mounted about an axis parallel to the latching cleat and has a

  magnetic valve that can be activated by electroai-

  mant, and for the end of the telescopic slide cooperating with the interlocking cleat, there is provided a

  guide surface directed towards the locking tab.

  The pivoting engagement element comprising a magnetic valve allows a particularly precise positioning of the engagement cleat, which allows a further reduction of the trajectory, and a significant lever ratio. It is preferably provided in the context of the invention that an inclined surface which deflects the end of the telescopic slider cooperating with the interlocking cleat is connected to the interlocking cleat towards the abutment surface of the disarming lever. Thus, in the engaged state, the telescopic slide does not interfere with any

  other room, especially when the disarm lever

  at the same time carries the oscillating weight.

  The advantages of the device according to the invention are particularly advantageous when the electromagnet is controlled by an electronic circuit having a timer relay responding to the arming of the slide.

  tightening, as is known per se from the document DE-

A-44 13 685 cited above.

  In what follows, the invention will be described and explained, by way of example, with reference to the figures of the appended drawing, o:

  - Figure 1 shows a weapon according to the invention-

  tion, in the disarmed state; - Figure 2 shows the movable breech of this weapon, in the arming state; - Figure 3 shows the same movable cylinder head

during disarmament.

  In FIG. 1, the casing of the movable cylinder head 1 is hatched and is only partially indicated. In its ceiling 2 is guided a clamping slide 3. A clamping arm 4 is pivotally mounted in the casing of the movable cylinder head 1 around an axis 5. It comprises in the center a nut 6, at the level of which is guided in the usual way a guide rod 7 and a striker spring 8 is applied. This acts with its other end on a striker element 9. The clamping slide 3 has at its lower face, which extends inside the movable cylinder head housing 1, a recess 10 cooperating with the clamping arm 4, a hooking tooth

11 and a control blade 12.

  In addition, in the movable cylinder head housing 1, a stop lever 15 can pivot around an axis 16 and is biased by a spring, which stop lever ends in a holding latch 17. In the position of armament, this lock cooperates with the hooking tooth 11 and is here controlled for example by a stop disc 18. Its action is described in patent document DE-195 03 803.7 and constitutes only one of the many modes of possible realization. A disarming lever 19 can pivot around an axis 22 mounted near the stop lever 15 and carries, in the embodiment shown, an oscillating weight 20. The purpose of such oscillating weights is to automatically disarm the weapon upon impact. In addition, a return spring is provided.

  21, which acts on the clamping arm in the direction of its disarming position.

  According to the invention, a mini-magnet (electromagnet)

  (in lines and dots) is now placed inside

  laughing of the movable breech casing 1 and fixed by means of screws 31. A supply duct, not shown, is arranged inside the weapon so as to withstand impacts. A guide surface 32 and a pivoting axis 33, on which is

  mounted an engagement element 34, are part of the mini

  magnet 30 or are fixedly connected thereto. This engagement element has a magnetic valve 35 biased by a spring 36, and on which the magnetic field produced by the mini-magnet 30 acts.

  the engaging element 34 has a locking heel

  ment 37 which, when magnet 30 is at rest, is applied

  quée against the guide surface 32, and a cleat

  latch 38 to which an inclined surface is connected

  39, which will be discussed further below.

  A telescopic slide generally designated by 40 is connected at one end 41, via the pin 42, to the clamping arm 4, on which the return spring 21 acts. The telescopic slide has a tubular part 43, containing a spring at pressure 44,

  which acts on the other end 45 of the telescopic slide

  than 40. This has a latching surface 46, which in certain operating states, cooperates with the latching cleat 38. The tubular part 43 and the end part 45 are telescopically inserted one into the 'other, a transverse pin 47 mounted in one piece fits into a groove 48 of the other piece, which serves

guide and stop.

  FIG. 2 now shows the cocking position of the weapon, which is obtained, starting from the position of FIG. 1, by pushing the clamping slide 3 forward. In this case, the arm of tightening 4 pivots forward and the striker spring 8 is armed, until the holding latch 17 passes

  behind the attachment tooth 11 and maintains the slide

  clamping bucket in this stretched position. By the pivots-

  ment towards the front of the clamping arm, the telescopic slide 40 is compressed by compression of the spring 44 and its front engagement surface 46 is applied, under the action of the spring 44, against the engagement cleat 38

and the guide surface 32.

  FIG. 3 shows the same device during disarming, without having previously fired. This disarming is triggered by a short electric pulse acting on the mini-magnet 30, which pulse is generated by an electronic control not shown. A possible mode of operation of such

  electronic control is described in document DE-A-

43 13 261.

  By this impulse, the magnetic valve 35 is briefly biased against the force of the spring 36 until

  that, as shown, it is applied against the mini

  magnet 30. In this case, the latching element 34 rotates clockwise, whereby the latching cleat 38 releases the latching surface 46 from the telescopic slide 40, and the inclined surface 39 deflects it. ci upwards, so that it presses against an end surface 51, which is provided at the free end 50 of the disarming lever 19. Here, the end surface 51 is milled in the oscillating weight 20. As a result, the latter pivots clockwise (direction of arrow 53), the eccentric 52 pushes the stop lever 15 downwards, the retaining bolt 17 releases the hooking tooth 11, and then the cocking lever 3, the clamping arm 4 and the return spring 8 return to their starting position which is

shown in Figure 1.

  The invention is not limited to the embodiment

  tion which has just been described, but on the contrary includes any variant taking up, with equivalent means, the

  essential characteristics stated above.
