Definitions

  • the present invention relates to a firearm trigger arrangement, a firearm trigger system, and a firearm comprising the firearm trigger system.
  • a firearm typically comprises a firearm trigger arrangement actuating a firing of the firearm. More specifically, a pull of the trigger of the firearm trigger arrangement actuates, at the trigger point, movement of springs and/or levers by which stored energy may be released, for example, by a gun powder explosion or a decompression of a gas. A portion of the released energy is then converted, in the firearm, into the kinetic energy of the projectile leaving the firearm. A small amount of force on the trigger may thereby initiate a large force by which the projectile is pushed forward.
  • a marksman may therefore optimize the grip of the firearm by selecting a firearm having a handle with the proper size and shape fitting the hand.
  • a goal by practise shooting is to perfect of the pulling motion of the finger to avoid undesired movement of the firearm when pulling the trigger, which may lead to the shot being off mark.
  • the trigger-pull characteristics of the firearm may further influence the precision.
  • improved performance during target shooting may be achieved by changing parameters such as size and shape of the trigger, the movement of the trigger, the length of the pull, and the pull weight.
  • a firearm trigger arrangement comprises a linear rail guide comprising a rail and a carriage, wherein the linear rail guide comprises a linear rolling-element bearing, and a trigger, wherein the trigger is supported by the linear rail guide and whereby a linear sliding motion of the rail and carriage relative to each other is provided in response to a pulling of the trigger.
  • a firearm trigger arrangement allowing for linear sliding motion of the trigger upon pulling is provided.
  • the linear motion of the trigger reduces deflection of the firearm caused by the pulling of the trigger.
  • the linear motion of the trigger is advantageous as transfer of a pivoting motion, which may be caused by the pulling of the trigger, is mitigated.
  • a conventional trigger arrangement comprising a pivotally housed trigger, for which the pivoting motion may be mediated to the firearm when pulling the trigger.
  • an improved shooting precision is achieved by the linear sliding motion of the trigger.
  • the wording firearm should be construed as a handheld weapon such as a barrelled weapon, e.g. a rifle or a pistol, from which a projectile may be launched as a result of an actuation.
  • the launching of the projectile may be driven by the action of an explosive force, i.e. by a gun powder explosion, or by means of compressed air or other gas such as for air guns or air rifles.
  • the launching of the projectile may, moreover, be by means of stored energy in a string such as for a crossbow.
  • the firearm may be a manual, semi-automatic or automatic weapon.
  • the firearm trigger arrangement should further be understood as the arrangement which provides motion of the trigger in response to the pulling.
  • the relative sliding motion of the firearm trigger arrangement may, moreover, directly, or via a firearm trigger mechanism allow for transfer of energy to a projectile such as a bullet or arrow.
  • rolling-element bearing should be construed as a bearing which may carry a load by placing rolling elements between two sliding elements, e.g. the rail and the carriage.
  • the sliding elements may according to some embodiments be referred to as races.
  • the relative motion of the sliding elements causes the rolling elements to roll with low friction.
  • the relative motion of the sliding elements may or may not comprise a sliding motion of the rolling elements.
  • the wording linear sliding motion should be understood as a relative free movement between two parts, i.e. the rail and the carriage of the linear rail guide.
  • the rolling-element bearing may be caged.
  • the rolling-element bearing may be of recirculating type.
  • the rolling-element bearing may comprise a ball bearing or a roller bearing.
  • the linear rail guide may comprise the caged linear rolling-element bearing, also referred to as ball or roller bushing or shaft guiding, typically comprising a cage with balls or roller, which may be of hardened steel.
  • the rotational motion of the balls or rollers relative to the rail allows for reduced friction and a smooth relative motion between the rail and the carriage.
  • the caging may mitigate the balls or the rollers from falling out, even when the rail and the carriage are separated from each other.
  • the linear rail guide allows for guiding and free motion along a one-dimensional direction.
  • a lower friction may, moreover, be provided by using a linear rail guide comprising linear caged rolling-element bearings.
  • a smoother movement of the trigger is also provided.
  • the arrangement of the rail and the carriage may further provide motion which is substantially one-dimensional. Hence, motions in other directions may be reduced, motion which otherwise may deflect the firearm when the trigger is pulled.
  • the linear sliding motion of the trigger further simplifies the designing of the trigger-pull characteristics of the firearm. Rotational motions which otherwise may be present when a conventional pivotable arranged trigger is pulled are thereby reduced.
  • the trigger may be supported by the linear rail guide by means of a distal end of the trigger being attached to the linear rail guide.
  • a simple arrangement is thereby provided in which a major portion of the trigger is accessible to the marksman pulling the trigger.
  • the trigger may be supported by the rail of the linear rail guide.
  • the trigger may be supported by the carriage of the linear rail guide
  • the carriage or rail may be adapted to be fixedly attached to a housing of a firearm.
  • the firearm trigger arrangement may be adapted to be removably attachable to a housing of a firearm.
  • a versatile firearm trigger arrangement which may be fitted, retrofitted and refitted to the firearm may thereby be provided.
  • a simplified replacement of the firearm trigger arrangement may further be provided.
  • a single firearm trigger arrangement may moreover be used for different firearms.
  • a firearm trigger system comprising the firearm trigger arrangement described above.
  • the firearm trigger system further comprises a firearm trigger mechanism, wherein the firearm trigger arrangement is coupled to the firearm trigger mechanism such that the linear sliding motion of the rail and carriage relative to each other is transferred to the firearm trigger mechanism.
  • a simplified design of the firearm trigger system is provided by the transfer of motion between the firearm trigger arrangement and the firearm trigger mechanism being linear.
  • a versatile firearm trigger system is further provided which may be fitted, retrofitted and refitted onto different firearms.
  • the firearm trigger system may thereby be seen as a replaceable stand-alone-system or a kit adapted to be arranged on a firearm.
  • a simplified replacement of the firearm trigger system may thereby be provided.
  • a single firearm trigger system may moreover be used for different firearms. Hence, a marksman or another person may swap the firearm triggers system of the firearm.
  • different firearm triggers systems may have different characteristics such as length of the pull, and the pull weight.
  • a firearm comprising the firearm trigger system according to the above is provided.
  • the function and benefits of the firearm are described above in relation to the firearm trigger arrangement and the firearm trigger system.
  • the above mentioned features, when applicable, apply to this third aspect as well. In order to avoid undue repetition, reference is made to the above.
