Definitions

  • the invention relates to an aperture mount according to the preamble of claim 1 according to German patent application P 33 08 676.1.
  • German patent application P 33 08 676.1 An essential part of the German patent application P 33 08 676.1 is the space-saving arrangement of discharge channels for empty belt links from a change-in-position belt feeder that can be changed for operational reasons, whereby there is a space between the two discharge channels for empty belt links in which a cradle with the barrel weapon stored in it for control purposes of the latter is pivotable about an axis parallel to the tube core axis.
  • the invention has for its object to develop an aperture mount according to the German patent application P 33 08 676.1 in such a way that, in addition to easy maintenance of the individual components and their space-saving arrangement, the greatest possible protection of the crew of a combat area behind the aperture is ensured in different operating states.
  • a cradle 22 which can be pivoted about an axis 25, of a machine gun 20 indicated here and an interchangeable belt feeder 26, which can be pivoted about an axis 35, are arranged in a diaphragm 10 with an elevation axis 11.
  • Empty channels 38, 40 and 44 show the extensive use of the interior of the panel 10 under cramped conditions.
  • the cradle 22 is shown in full line in a first position for operating the machine gun 20. In its second position, which enables the machine cannon 20 to be checked when the change belt feeder 26 is installed, the cradle 22 is shown in broken lines.
  • the axis 35 for receiving the interchangeable belt feeder 26 has a collar 140 and is detachably fixed in a diaphragm-fixed receptacle 142 by means of a crown nut 144.
  • a frame 146 has, in addition to a counter bearing 148 for a free end 150 of the axis 35, a device SV for the operational pivoting of the change belt feeder 26 and serves to releasably receive a protective hood 152.
  • a front armor FP of the panel 10 has a left part 156 and a right part 158, between which there is an overlap 1GO. There is a passage for the tube 21 ' 1 62 provided in the front armor FP.
  • the left part 156 has a groove 164 and the right part 158 has a groove 166. In a shown first position, elements 168, 170 which are fixed against the cradle engage in the grooves 164, 166 which are inclined relative to the horizontal and prevent mutual relative movement of the two parts 156, 158.
  • the element 158, 170 is a respective Bowden cable 172, 174 with a restoring compression spring 176, 178 assigned.
  • the compression springs 176, 178 hold the elements 168, 170 in place.
  • In this first position there is a positive connection between the cradle 22 with the two parts 156, 158 in a direction transverse to the longitudinal axis of the weapon.
  • both parts 156, 158 as a unit are moved a distance 180 from the left (full-line line) shifted to the right (dash-dotted line).
  • a thick-walled apron 182 is provided on the panel 10 in order to protectly cover the distance 180, that is, to avoid a gap at the front.
  • the device SV for the operational pivoting of the change belt feeder 26 has a pivot lever 186 with a handle 188 for moving a shaft 184.
  • a pinion 190 is arranged on the shaft 184, which meshes with a toothed segment 192 of a lever 194.
  • the lever 194 like the change belt feeder 26, can be pivoted about the axis 35.
  • a driver pin 196 on the lever 194 engages in a recess 198 in the interchangeable belt feeder 26.
  • the frame 146 is detachably fastened in the panel 10 in a manner not shown.
  • the protective hood 152 is easily removable from the frame 146.
  • Fig. 3 allows quick release devices 200 for the aforementioned rapid loosening and fastening of the protective hood 152 to the Frame 146, in the latter closable openings 202, 2 0 4 for loading and unloading the change belt feeder 26, the counter bearing 148 for the flying end 150 of the fixed axis 35 and the pivot lever 186 with the handle 188 of the device SV for pivoting the change belt feeder 26 recognize .
  • An angle mirror insight 206 completes the overview of the arrangement.
  • the pivot lever 186 can be moved both in the direction of two arrows 208, 210 (see FIG. 2) and in the direction of two arrows 212, 214.
  • Display means not shown, provide information about the operating state of the change belt feeder 26.
  • the lever 194 has three incisions 2 1 6, 218 and 220 and two end stops. 222, 224.
  • a cam 226 is mounted on a shaft 228 with a compression spring 230.
  • the lever 194 is pivoted via the pinion 190 and the toothed segment 192, not shown here, and with it, via the driving pin 196, the change belt feeder 26.
  • the pivoting movement is limited by the two end stops 222, 224.
  • the cam 226 By pivoting the lever 186 back in the direction of the arrow 210 (see FIG. 2), the cam 226 reaches the selected incision and is held in place by the locking member 232.
  • Each incision 216, 218 and 222 corresponds to the respective operating state "FIRE AMMUNITION A", “NEUTRAL POSITION” and "FIRE AMMUNITION B".
  • Each of the incisions 216, 218 and 220 is assigned a respective touch limit switch 234 for cooperation with the cam 226. This influences the display means, not shown, which have already been mentioned. One yourself The resulting operating status is therefore always recognizable for the relevant members of the crew in combat area 154.
  • a shaft 236 shown in FIG. 9 has a hand lever 238.
  • the shaft 236 is axially movable in the direction of an arrow 242 against a return spring 240.
  • a spring-loaded wedge 244 is pulled out of its locking position (see FIG. 6) between a surface 246 in a pocket 248 of a housing 250 and the upper sides 252, 254 of two toggle lever halves 256, 258.
  • the toggle lever half 256 is pivoted clockwise, and the second toggle lever half 258 is pivoted via an articulation 260 and a surface 262 through an intermediate position (see FIG. 7) into an end position (see FIG. 8).
  • a free end 264 of the second toggle lever half 258 moves away from a counter surface 266 on the cradle 22 which is in the operating position and releases it for pivoting clockwise into its control position (see FIG. 8). After pivoting the cradle 22 back into the operating position, it is fixed again in reverse order by actuating the device FV.
  • the spring loading of the wedge 244 makes vibration-related changes in distance between the relevant surfaces harmless.
  • a deflection of the toggle lever KH that opens by 2 makes it easier to operate when the cradle 22 is under load.
  • a supportive Force is less than the friction forces that occur. Thanks to the arrangement in the event of vibration, these need not be taken into account.
  • the wedge 244 is advantageously designed according to its angle and the force of the spring such that the opening component of the toggle lever KH is compensated for when all frictional forces are eliminated.
  • the device FV can be operated without any significant effort. This proves to be particularly advantageous when the cradle 22 is under load, for example in the event of a fault.
  • the precise position of the cradle 22 in its operating position can be ensured by readjustment plates 272, 274 which can be provided in the regions 268, 270.
  • the pivotability of the toggle lever KH into the pocket 248 advantageously creates a space F for the pivoting of the cradle 22 in a space-saving manner.
  • the two-part design of the front armor FP and its top 276 and bottom guide 278 can be seen from FIG.
  • the two parts 156, 158 of the front armor FP can be pushed apart.
  • the overlap 160 is removed and the machine gun 20 can be pulled out of the front panel 10.
  • Locking bolts 284, 286 prevent the two parts 156, 158 from being pulled out of the guides 276, 278.
  • the passage 162 for the weapon barrel 21 'in the combined front armor FP is on the outside with a acceptable additional protection 288 provided.
  • the two elements 168, 170 are simultaneously moved axially by means of their Bowden cables 172, 174 against the restoring force of the springs 176, 178 from their first to the second position. In a manner not shown, one can. Lock the handle to operate the Bowden cables 172, 174 in the second position.
  • the change belt feeder 26 can remain fixed to the diaphragm in all the operations to be carried out on the machine gun 20. If the replacement belt feeder 26 is to be removed, the procedure is as follows: the protective hood 152 is released from the frame 146. Then the frame 146 is detached from the panel 10 and removed. Now the change belt feeder 26 can be pulled off the axis 35 into the combat area 154. Here, the cradle 22 can remain in the operating position with the stored machine gun 20, so it does not need to be pivoted.
