Definitions

  • the invention relates to a wedge lock for a weapon with a returnable to a pipe cradle gun barrel and a bottom piece in which a transverse to Rohrseelenachse slidably disposed, operable by a ⁇ ffnerwelle closure wedge is provided.
  • US-A-3866513 discloses a wedge lock for a weapon.
  • the invention has for its object to provide a simply constructed wedge closure, with which an automatic opening of the closure at high firing order is possible without an additional external drive is required.
  • the invention is based essentially on the idea, similar to weapons with bottom closure to provide a curved path on a weighing guide means for guiding a bolt-shaped driver, although the driver does not directly cause lifting and lowering of the closure wedge, but causes a rotation of the opener, which then in turn on the closure wedge, eg via a gear or lever gear, acts.
  • the curved path consists of at least two adjoining sections, the first section of the curved path being arranged on a first part of the guide device directly adjoining the inlet region and against the pressure of a spring about one vertically to the longitudinal axis of the pin-shaped carrier arranged axis is pivotally formed, such that the return of the gun barrel of the peg-shaped driver laterally pivots the first part of the barrel and thereby passes into the inlet region.
  • Such a guide device has, inter alia, the advantages that only rotated the first section during the return of the gun barrel by the peg-shaped driver whose mass is low, so that it can be accelerated to a value of> 15 m / s for a fast shooting sequence.
  • the curved path has an approximately sinusoidal course. As a result, a jerk and shock-free sliding movement of the peg-shaped driver is ensured during the opening stroke.
  • the peg-shaped driver is supported not only on the curved path, but is also guided by a fixed curve arranged above the curved path, so that the driver is guided along a rising groove-shaped recess.
  • the upper curve prevents the closure from being thrown to the outside at high forward velocities of the weapon barrel (e.g., 2.5 m / s).
  • the length of the first portion of the curved path is at least 60% of the length of the entire curved path.
  • a base plate is provided on which the second portion of the cam track bearing second part fixed and the first portion of the cam track bearing first part is pivotally mounted.
  • Fig. 1 is denoted by 1 a weapon with respect to a pipe cradle 2 retractable gun barrel 3.
  • the gun barrel 3 is connected at the rear with a bottom piece 4, which receives a cross wedge shutter 5.
  • the cross wedge closure 5 comprises a transversely to the tube axis 6 slidably disposed closure wedge 7 and an opener shaft 8 shown in dashed lines, which is connected to ⁇ ffnerhebeln 9, which engage on opposite sides of the closure wedge 7.
  • the opener shaft 8 is connected on its right side facing the cradle 2 with a control lever 10, on which a pin-shaped carrier 11 is attached. This driver 11 engages in a guide device 12 attached to the tube cradle 2.
  • the guide device 12 includes a bolted to the cradle 2, for example, and off Cast iron existing base plate 13 ( Figure 3 ), at the for guiding the carrier 11 during the advance of the gun barrel 3 from a lead-in area 14 to a highest point 26 rising cam track 15 (FIG. Fig.2 ) is arranged, which has an approximately sinusoidal rise.
  • an upper side wall 16 is provided, which has the same course as the cam track 15, so that the driver 11 is guided in a groove-shaped recess 17.
  • the cam track 15 is composed of two adjoining sections 18, 19, the first section 18 of the cam track 15 being formed by a first part 20 of the guide device 12 adjoining directly to the inlet area 14.
  • This first part 20 is also made of cast iron (eg 14NiCr18-Stahlfeinguß) and is arranged about a perpendicular to the longitudinal axis of the peg-shaped driver 11 axis 22 pivotally mounted on the base plate 13 of the guide means 12 and is in his in Fig.2 shown rest position held by a plunger 23 ( Figure 3 ).
  • This plunger 23 is acted upon by a spring 24, which is supported on the base plate 13.
  • the second portion 19 of the cam track 15 is formed by a second, fixedly connected to the base plate 13 and also consisting of cast iron part 25.
  • the guide means 12 for guiding the carrier 11 during the return of the gun barrel 3 has a relation to the highest point 26 of the cam track 15 deeper straight guide track 27, which merges into the inlet region 14 of the cam track 15.
  • the peg-shaped carrier 11 also slides on the guideway 27 to the rear and pivots the provided with the first portion 18 of the cam track 15 first part 20 from the gun barrel 3 laterally into a corresponding recess of the tube cradle 2, so that the driver 11 largely unhindered in the inlet region 14 of the cam track 15 passes.
  • the new bullet is applied by means of a loading machine (not shown) and the introduction of a new propellant charge ,
  • a release lever By means of a release lever (not shown), the closure wedge 7 is closed, wherein the peg-shaped carrier 11 follows the steeply sloping transition region 28 between the cam track 15 and the guideway 27, so that the weapon barrel 3 is closed by the closing wedge 7 falling down. Then then the next shot can be triggered.
