Definitions

  • the present invention broadly relates to firearms and, more specifically, concerns a sports or target piston, especially a pistol which in its conception and design differs from the state-of-the-art sports pistols in that the breechblock mechanism and trigger mechanism are much simpler and inexpensive to manufacture, while nonetheless affording maximum firing accuracy.
  • Such type pistols wherein the firingand breechblock mechanisms function independently of the trigger system, always require two types of movement on the part of the shooter, namely one movement for the purpose of lowering or rotating the breech-block cylinder or the breech lock coupled with the cocking or tensioning of the firingand breechlock mechanism, and a second movement for setting the trigger system. All of these constructions are very complicated, requiring extreme accuracy in manufacture which, in turn, has a considerable influence upon the final cost of the pistol.
  • a primary objective of the present invention is to provide such a pistol which capably and effectively fulfills the existing need.
  • Another, move specific objective of the present invention is to provide an improved construction of pistol which only requires a single movement for cocking the firing mechanism, for initiating the operation of the breechblock mechanism, and for setting the trigger system, and additionally, simplifies the construction of the otherwise complicated and expensive breechblockand trigger mechanisms.
  • Yet a further significant objective of the present invention relates to an improved construction of sporting or target pistol which is extremely simple to use, requiring a minimum of manipulations, economical to manufacture, provides for maximum firing accuracy, and is not readily subject to malfunction.
  • the inventive pistol is manifested by the features that the breechblock is constructed as an angle-lever breechblock mechanism which can be actuated by means of a cocking or tensioning lever mounted laterally of the breechblock mechanism.
  • FIG. I is a fragmentary longitudinal sectional view of the inventive angle-lever breechblock mechanism in closed condition as provided for a pistol;
  • FIG. 2 is a longitudinal sectional view of the anglelever breechblock mechanism of FIG. I, but this time depicted in its open position;
  • FIG. 3 to 5 depict respective fragmentary sectional views of the different components of the inventive pistol, and specifically wherein:
  • FIG. 3 illustrates details of the trigger mechanism in the unset condition
  • FIG. 4 shows the cocking operation between the breechblock mechanism and the trigger mechanism
  • FIG. 5 illustrates the breechblock mechanism in the closed condition and the trigger mechanism in the set condition.
  • FIG. 1 illustrates the exemplary embodiment of inventive sports or target piston depicted in FIG. 1 illustrates the angle-lever breechblock mechanism in its closed position, embodying the breech block or breechblock cylinder 3 and the breech lock 7, supported by the support bolt or pin 8 vertically mounted in the breechblock housing 2.
  • the breechblock cylinder 3 is coupled by a connection lever 5 and the pivot bolts or pins 6 and 4 with the breechblock or breech lock 7.
  • the cocking or tensioning lever 14 threadably connected laterally of or to one side of the breech lock 7, it is possible to laterally open and close at the left the angle-lever breechblock mechanism.
  • FIG. 2 illustrates this angle-lever breechblock mechanism in its open position.
  • the cocking or tensioning lever 14 is oriented Substantially perpendicular to the breechblock cylinder 3, the extend of Pivoting of this cocking lever 14 into the illustrated open position being limited by the lateral impact of the breechblock lock 7 at the breechblock housing 2 at location 2a thereof.
  • the pivot bolt 6, located at a predetermined distance from the supporting bolt 8, describes a circular arc. Due to the attendant action of the connection or connecting lever 5, mounted at the pivot bolt 6 of the breechblock lock 7 and at the pivot bolt 4 of the breechblock cylinder 3, the just mentioned breechblock cylinder 3 is retracted back within the bore 2b of the breechblock housing 2. During this movement the firing pin 9, subjected to the action of the firing pin spring 10, is located in its forward fired position. By virtue of this rearward movement the breechblock cylinder 3 frees the breech or changing chamber 38 of the breechblock housing 2. As a result, the angle-lever breechblock mechanism is thus disposed in its uncocked open condition or state.
  • FIGS. 3 to 5 inclusive wherein initially reference is made to the illustration of FIG. 5.
  • the trigger sear 11 with its catch or lock nose 29, and pivotally mounted upon a bolt member 30 in the handle or stock 15, fixedly retains in position the cocked or loaded firing pin member 9 owing to the action of the upwardly effective spring member 16 bearing against the underside of the trigger sear 11 as shown.
  • the disconnector 27, subjected to the action of the spring member 28, is mounted upon a bolt or pin 37 secured in the handle or stock portion 15.
  • This disconnector 27 bears with its downwardly depending nose portion 33 upon the trigger arm nose 34.
  • the configuration of the disconnector 27 is selected such that the mass thereof located beneath the point of rotation, namely below the pivot bolt 37, is so large that on the one hand the spring member 28 need not be too strong and the moved mass can equally release the trigger seal 11.
  • the pressure of the nose portion or detent 34 of the disconnector 27 against the trigger arm nose 34 should not be too great, otherwise for an adjusted pressure point the trigger rod 26 no longer possesses the requisite play or required movement capability.
  • the trigger arm or rod member 26 contains all of the adjustment possibilities for the double-hair trigger screw 24 for the double-hair trigger, the pressure-point screw for the pressure point, the screw member 18 for adjusting the interengagement of the nose members of the trigger arm or rod 26 and the disconnector 27, as well as the screw member 19 serving to secure the screw 18 and the adjustable trigger tongue or trigger member 17.
  • FIG. 3 illustrates details of the trigger mechanism in its unset squeezed-off or rest position.
  • the firing pin member 9 is no longer loaded and the breechblock cylinder 3 is closed.
  • the trigger sear 11 is disposed beneath the nose member or projection 35 of the firing pin 9 and the disconnector 27 is likewise released or unloaded.
  • this disconnector 27 is no longer retained by the nose member 34 of the trigger rod or arm 26, so that the spring 28 moves the disconnector 27 about its point of rotation 37 until such disconnector 27 bears against the trigger sear 11, as shown.
  • the cam portion 32 of the disconnector 27 is in its uppermost position.
  • FIG. 4 illustrates the cocking or tensioning operation occuring between the breechblock mechanism and the trigger mechanism.
  • the firing pin member 9 in its previously considered forward squeezed-off" or non-loaded position, as shown in FIG. 4, likewise moves rearwardly together with the breechblock cylinder 3 and thus releases the trigger sear 11.
  • Spring member 16 lifts this trigger sear 11 until it contacts its non-illustrated stop, and the trigger sear assuming the position of FIG. 4 which conveniently can be designated as the catch position for the firing pin member 9.
  • the pivot bolt member 4 also moves rearwards.
  • FIG. 5 illustrates the breechblock mechanism in its closed position and the trigger mechanism in its set condition.
  • the breechblock cylinder 3 is moved forwards.
  • the firing pin member 9 simultaneously moves forwards together with the breechblock cylinder 3 until the nose member 35 of this firing pin 9 is held by the catch nose 29 of the trigger sear l1, urged by the spring member 16 upwards until it makes contact with the firing pin-nose member 35.
  • the breechblock cylinder 3 continues to move for a certain distance until it contacts the barrel 1; this pre-cocking path is conveniently designated the firing path.
  • the catch nose 29 is pressed downwardly and therefore releases the firing pin member 9.
  • Firing pin member 9 is displaced forwardly owing to the action of the tensioned firing pin spring 10 and thereby fires the cartridge.
  • the trigger mechanism consisting of three main components (trigger seat 11, disconnector 27, trigger arm 26) can be adjusted both for double-hair triggers as well as also for pressure-point triggers.
  • the function is extremely simple.
  • the trigger mechanism possesses a short release time and a light-action of the impact of the disconnector 27 upon the trigger sear 11 which, in turn, releases the firing pin 9, and does not affect the firing precision.
  • the herein described and illustrated angle-lever breechblock mechanism together with the trigger mechanism is extremely simple both in operation and manufacture and in the area of high precision pistols provides a completely new and improved construction.
  • By means of the cocking or tensioning lever it is possible to both actuate the striker or impact mechanism and the function of the breechblock mechanism as well as also to preset the trigger system.
  • the trigger system is constructed in an extremely simple manner and can be adjusted, as mentioned above, both for pressurepoint triggers as well as for double-hair triggers.
  • the barrel dimensions and the bore relationships and also the sighting can be accommodated to the exceptional firing accuracy.
  • a firearm comprising an angle-lever breechblock mechanism, and an actuating lever laterally mounted for actuating said angle-lever breechblock mechanism, said angle-lever breechblock mechanism comprising a breechblock cylinder and a breech lock, a connecting lever, a first pivot bolt for connecting one end of said I connecting lever with said breech block cylinder, and a second pivot bolt for connecting the other end of said connecting lever with said breech lock; a trigger mechanism incorporating a trigger member operatively connected with a trigger arm and a displaceably mounted disconnector member cooperating with said trigger arm, said first pivot bolt being mounted at said breechblock cylinder and cooperating with said disconnector member such that upon opening said angle-lever breechblock mechanism and first pivot bolt acts upon said disconnector member to initially cause release of said trigger arm, whereupon said trigger arm and disconnector member interengage with one another to preset said trigger member.
  • a target piston comprising a trigger mechanism and a breechblock mechanism, said breechblock mechanism incorporating a breechblock cylinder and a breech lock, lever means for operatively interconnecting said breechblock cylinder with said breech lock, said breech lock being pivotably disposed adjacent said breechblock cylinder, said lever means having end portions respectively pivotably secured to said breechblock cylinder and said breech lock, and means carried by said lever means for setting said trigger mechanism.
