Definitions

  • the invention relates to an adjustable rifle piston, in particular for an assault rifle, according to the preamble of claim 1.
  • Such a rifle butt is from the DE-A-1 553 855 known.
  • This has a movable shaft which is guided on a rifle fixed to the stable rail longitudinally displaceable.
  • a locking device is provided with a biased by a spring in a locking position locking pin which engages in cylindrical recesses on the underside of the handlebar mounted on the spar.
  • the provided for the engagement of the locking pin recesses are located in an elongated rib which is integrally formed on the underside of the spar.
  • the locking pin is displaceable over a arranged on the underside of the rifle piston handle from its upper locking position into a retracted release position. By pivoting the handle in one direction, the locking pin can be pulled out of the recesses to move the rifle piston between an extended and retracted position. For complete separation of the parts, however, the handle must be pivoted in the other direction.
  • the object of the invention is to provide an easy-to-use rifle piston of the type mentioned, which has a cost-effective lightweight construction and yet meets the high strength and safety requirements.
  • the guide part is made of plastic and contains a high-strength locking insert for engagement of the blocking element.
  • the locking insert is made of a fiber-reinforced plastic, preferably a glass fiber reinforced polyamide.
  • a fiber-reinforced plastic preferably a glass fiber reinforced polyamide.
  • a polyamide with a long glass fiber of approximately 14 mm has proven to be particularly advantageous, the proportion being in the region of 60%.
  • the locking insert is preferably connected via transverse pins with the guide part. As a result, the locking insert can be easily replaced if necessary.
  • the locking insert can also be glued or connected in any other suitable manner with the guide member.
  • the operating element is associated with a safety slide for preventing an undesired displacement of the locking element into a dismantling or assembly position. This can prevent the connection between the guide member and the piston from being accidentally disconnected.
  • a cover is suitably attached, which covers the front end of the guide tube in a rear Ausziehgna. This can avoid that dirt gets between the guide member and the piston.
  • FIGS. 1 to 4 is an especially designed for an assault rifle, adjustable rifle piston with a guide part 1 and a piston 2 shown, which is guided on the guide part 1 slidably.
  • the piston 2 contains an actuatable by means of a control element 3 locking element 4, by which the piston 2 can be locked in different extension positions relative to the guide part 1.
  • the preferably made of plastic piston 2 includes a guide tube 5 and provided with a recess 6 shoulder support 7, at its rear side a provided with a cover 8 piston cap 9 is fixed.
  • the piston 2 is displaceably guided on a rearwardly projecting guide sleeve 10 of the guide part 1.
  • On the underside of the substantially triangular in side view of the piston 2 formed as a control lever operating element 3 is arranged with the locking bolt 4 designed as a locking element 4 for engagement in a high-strength locking insert 11 in the guide part 1.
  • FIG. 2 shows, designed as a locking pin locking element 4 is guided displaceably in a corresponding opening 12 transversely to the longitudinal axis of the guide tube 5 and articulated at its lower end via a transverse axis 13 to the means of a cross pin 14 on the piston 2 pivotally mounted control element 3 such that the blocking element 4 is withdrawn by retracting the fog-like control element 3 from its upper locking position.
  • Trained as an operating lever control element 3 is housed in a corresponding recess 15 on the underside of the piston 2.
  • compression spring 16 By a in FIG. 2 schematically indicated compression spring 16, the control element 3 is pressed forward and thereby executed as a locking pin locking element 4 upwards into the locked position.
  • the compression spring 16 is clamped between a bore 17 of the control element 3 and a recess 18 of the piston 2.
  • a biased by a compression spring 20 in the direction of the control element 3 fuse slide 21 is also housed.
  • the safety slide 21 is guided displaceably within the recess 19 and is pressed by the compression spring 20 against a transverse pin 22.
  • FIG. 1 shows, the cross bolt 22 is slidably guided in a slot 23 of the piston 2 and can be moved by hand to the rear against the force of the compression spring 20.
  • the safety slide 21 has at the front a step with a shoulder 24 and a projection 25 which cooperate with a nose 26 at the rear end of the control element 3 in a manner to be described below.
  • Guide part 1 shown is also made of plastic and has at the bottom of the rearwardly projecting guide stub 10 a in FIG. 7 recognizable, downwardly open recess 27 for receiving the locking insert 11.
  • the in the FIGS. 2 to 4 Locking insert 11 shown contains three consecutive, inwardly wedge-shaped narrowing recesses 28, in which engages the wedge-shaped upper end of the locking element 4. Between the recesses 28 of the locking insert 11 is set back, so that between the recesses 28 according to FIG. 2 a small gap X between the piston 2 and the locking insert 11 results.
  • By upper transverse webs 29 of the locking insert 11 is anchored in the guide member 1 made of plastic.
  • the locking insert 11 preferably made of glass-fiber-reinforced polyamide or another fiber-reinforced plastic, is exchangeably connected to the guide part 1 via two transverse pins 30.
  • the locking insert 11 can also be glued or connected in any other suitable manner with the guide part 1.
  • a rotationally secure guidance of the piston 2 on the guide part 1 is ensured.
  • On the outer sides of the guide neck 10 are also several successive indentations 33 provided. Thereby, the friction between the guide part 1 and the piston 2 is reduced.
  • connection part 34 of the guide part 1 is on one side in the FIGS. 1 and 6 recognizable hinge 35 for attachment of the guide member 1 formed on a trigger housing of an assault rifle.
  • On the other side of the connecting part 34 is an in FIG. 2 recognizable recess 37 provided for a push button 36 of a piston backup.
  • the piston lock By actuating the print head 36, the piston lock can be released and the guide member 1 can be folded away laterally together with the piston 2 guided thereon.
  • the piston 2 On the side of the hinge 35, the piston 2 has a clip 38, by means of which the piston 2 in the folded-in position can be resiliently held on a hand guard of the assault rifle.
  • a cover 39 is attached, which is the front end of the guide tube 5 in the in FIG. 2 shown completely extended position of the piston 2 covered. Through the cover 39, the penetration of dirt between the guide member 1 and the piston 2 is to be prevented.
  • Locking position shown as blocking pin 4 is pressed over the spring-loaded control element 3 upwards in one of the provided for the different extension positions recesses 28.
  • the provided at the rear end of the control element nose 26 is formed such that it is aligned in the locking position with a front edge 40 of the piston 2. As a result, it can be prevented that a contactor hangs on the operating element 3 designed as a control lever.
  • the nose 26 of the control lever 3 By retracting the control element 3, the nose 26 of the control lever 3 enters the shoulder 24 of the spring 21 acted upon by the compression spring forward slide 21.
  • the shoulder 24 and the projection 25 are formed such that the nose 26 of the control element 3 in the front locking position of Safety slide 21 only reaches the projection 25 and thus the control element 3 only up to an in FIG. 3 shown first position can be withdrawn.
  • the upper end of the locking element 4 projects a little further into the gap X which is closed to the rear the locking insert 11 and the piston 2 in and thereby prevents the piston 2 can be completely withdrawn to the rear.
