Description

A WEAPON COMPRISING A SENSING ARRANGEMENT
The present invention generally relates to the field of weapons. In particular, the invention relates to a sensing arrangement configured to sense movement and/or presence/absence of a movable or removable part comprising a ferromagnetic or paramagnetic material in a weapon.
BACKGROUND ART Firearms are among others used by police and military. Often the firearms are not used very often and there is therefore a need for weapon training in order to keep skills up to date. Weapon training has often been accomplished with live ammunition at targets in specific firing range areas. One disadvantage of this procedure is the cost of the ammunition used.
Another disadvantage is that firing ranges require space, are not easily accessible and can often only be used in daylight. Further, live ammunition requires that hearing protectors are worn.
Today there are also simulated weapons provided with laser beams. The laser beams are detected by targets. Simulated weapons, weapons that are used for training and weapons that are used with ammunition often need different types of sensors in order to sense the position of different parts of the weapon. It is critical that these sensors are of high quality so that the sensors do not come off when parts of the weapon are moving.
It is therefore conceivable to assume that a market incentive exists to remove the mentioned limitations one way or the other. However, despite this incentive, and despite prior attempts to overcome problems relating to weapons there is still a need for a solution for weapons, which solution overcome or at least mitigates one of the above problems. SUMMARY OF THE INVENTION
It is therefore an object of the present invention to alleviate the above limitations. This object is attained by a sensing arrangement configured to sense movement and/or presence/absence of a movable or removable part comprising a ferromagnetic or paramagnetic material in a weapon. The sensing arrangement comprising: means for generating a magnetic field and at least one magnetic field sensor. The means for generating a magnetic field and the at least one magnetic field sensor are fixedly arranged on a non movable part of the weapon and arranged in relation to the movable or removable part so that when the movable or removable part moves the at least one magnetic field sensor can sense a magnetic field intensity change.
One of the main advantages of the present invention is the solution to the previously mentioned shortcomings. The invention eliminates the problem of sensors used in weapons or simulated weapons that come of when the weapon is used. This since the means for generating a magnetic field and the at least one magnetic field sensor are fixedly arranged on a non movable part of the weapon.
Yet another advantage is that there is no need for modifications to the original weapon, as holes and fixations means for the means for generating a magnetic field and at least one magnetic field sensor are not necessary.
BRIEF DESCRIPTION OF THE DRAWINGS
Objects, advantages and effects as well as features of the invention will be more readily understood from the following detailed description of exemplary embodiments of the invention when read together with the accompanying drawings, in which:
Figure 1 schematically illustrates a sensing arrangement according to an exemplary embodiment of the present invention.
DETAILED DESCRIPTION
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as device configurations in order to provide a thorough understanding of the present invention. It will be apparent to one skilled in the art that the present invention may be carried out in other embodiments that depart from these specific details.
Referring to figure 1 there is illustrated a sensing arrangement 100 configured to sense movement and/or presence/absence of a movable or removable part comprising a ferromagnetic or paramagnetic material in a weapon. The sensing arrangement comprises means 10 for generating a magnetic field and at least one magnetic field sensor 20. The means 10 for generating a magnetic field and the at least one magnetic field sensor 20 are fixedly arranged on a non movable part of the weapon and arranged in relation to the movable or removable part so that when the movable or removable part moves the at least one magnetic field sensor 20 can sense a magnetic field intensity change. The movable or removable part can in exemplary embodiments of the sensing arrangement 100 according to the present invention be a trigger of the weapon, a bolt of the weapon, a magazine of the weapon, a safety leveler of the weapon, a hammer of the weapon or another movable or removable part of the weapon.
The non movable part on which the means 10 for generating a magnetic field and the at least one magnetic field sensor 20 are fixedly arranged can in exemplary embodiments of the sensing arrangement 100 according to the present invention be the weapon frame.
The means 10 for generating a magnetic field can in exemplary embodiments of the sensing arrangement 100 according to the present invention be a bias permanent magnet or an electromagnet. The magnetic field sensor 20 can in exemplary embodiments of the sensing arrangement 100 according to the present invention be a Hall sensor or other type of sensor capable of sensing a magnetic field intensity change. As mentioned above the means 10 for generating a magnetic field and the at least one magnetic field sensor 20 are fixedly arranged on a non movable part of the weapon. Since the means 10 for generating a magnetic field and the at least one magnetic field sensor 20 are fixedly arranged on a non movable part of the weapon they will not move when the weapon is used in training or with ammunition. The means 10 for generating a magnetic field and the at least one magnetic field sensor 20 will therefore not be subjected to wear from i.e. vibrations as they would have been if they had been mounted on a part of the weapon that was moving when the weapon was used. Another advantage with that the means 10 for generating a magnetic field and the at least one magnetic field sensor 20 do not move when the weapon is used in training or with ammunition is that the risk that they come of is significantly reduced. Yet another advantage is that there is no need for modifications to the original weapon, as holes and fixations means for the means for generating a magnetic field and at least one magnetic field sensor are not necessary.
As also mentioned above the means 10 for generating a magnetic field and the at least one magnetic field sensor 20 are arranged in relation to the movable or removable part so that when the movable or removable part moves the at least one magnetic field sensor 20 can sense a magnetic field intensity change. The means 10 for generating a magnetic field generates a magnetic field that can be sensed by the at least one magnetic field sensor 20. When the movable or removable part that comprises a ferromagnetic or paramagnetic material moves in the magnetic field generated by the means 10 for generating a magnetic field, this results in a change in the magnetic field. This change of the magnetic field is sensed by the at least one magnetic field sensor 20.
Thus it is possible for the sensing arrangement 100 according to the present invention to sense movement and/or presence/absence of a movable or removable part comprising a ferromagnetic or paramagnetic material in a weapon.
In yet another exemplary embodiment of the present invention the means for generating a magnetic field and the at least one magnetic field sensor are fixedly mounted on a circuit board mountable in the weapon or replicated weapon. In a further exemplary embodiment of the sensing arrangement 100 according to the present invention the means for generating a magnetic field 10 is arranged on the at least one magnetic field sensor 20.
Yet another aspect of the present invention is a weapon comprising the sensing arrangement according to any of the previously described embodiments. The weapon can be a replicated weapon.
Yet a further aspect of the present invention relates to a simulator system comprising the weapon described above. The simulator system can be a system for simulating recoil or hammer cocking.
The detailed description is of the best mode presently contemplated for practicing the present invention. It is not intended to be taken in a limiting sense, but is made merely for the purpose of describing general principles. The scope of the invention is to be ascertained with reference to the issued claims.
