Definitions

  • the invention relates to a barrel weapon according to the preamble of claim 1.
  • the hand release lever In the case of automatically moving opening and closing devices, it is necessary to carry out the wedge movement manually using a hand release lever before the first shot or in the event of faults. To open the locking wedge, the hand release lever must overcome not only the wedge weight and the frictional forces, but also the force of a spring, which is biased for the closing movement of the locking wedge.
  • a manual opener is used to avoid long lever lengths and swivel ranges, as a ratchet working in a small swivel range together with an additional transmission gearbox, but with the disadvantages that a Loss of time arises due to the large number of strokes to be carried out and in order to be able to hold the locking wedge, an additional safety device is required, which must be switched off again after each complete opening of the locking wedge.
  • This complex opening and closing device which consists of a large number of individual parts, has the further disadvantage that a jamming closure can only be closed with a special tool.
  • the object of the invention is to provide a simple construction in the construction consisting of a few parts for a barrel weapon of the type mentioned for the opening and closing movement of a breech wedge, in which the opening movement by hand in a small angle of rotation without overcoming a hand release lever Spring force is easy to carry out and after returning the hand opener lever to its rest position, the locking wedge can automatically take the locking position, and the hand opening lever should enable an automatic sequence of the locking wedge movements together with the device.
  • the invention enables a pre-tensionable piston-cylinder unit to be accommodated by means of a hollow body which is designed as a hollow body and is simple in construction, so that when the locking wedge is opened from the locking position during a direct pivoting movement of the hand opening lever about the opening shaft, no pretensioning force of the springs is required for the closing stroke of the locking wedge.
  • the piston-cylinder unit necessary for the closing stroke is integrated within the hand opener lever, the springs in the piston-cylinder unit are preloaded when the hand opener lever is returned to its rest position, so that only the frictional forces have to be overcome for the opening of the locking wedge in addition to the wedge weight.
  • the advantageous distribution of the spring pretensioning force on the return swing stroke of the hand opener lever allows for a favorable distribution of the low hand forces that arise during the opening and closing by opening the locking wedge during a single swing stroke in a small swivel range and still allows, with a space-saving simple arrangement consisting of a few parts, an uncomplicated, fully automatic operation of the opening and closing device of the locking wedge.
  • the hand release lever is designed as a thin-walled tube having an oval cross-section and widening conically towards the lever attached to the opening shaft, the shape of which gives the hand release lever stability in addition to a spacious interior and a light design of everything, as well as represents a safety protection against the movable piston-cylinder unit arranged in the interior.
  • a favorable position and swivel range adjustment during the expansion stroke of the piston-cylinder unit which can be swiveled via a lever around the opener shaft makes it possible to keep the torque which can be transmitted to the opener shaft constant in a region beyond half the swivel-back range of the lever . Due to the torque, which does not decrease, especially in the acceleration phase of the closing movement of the locking wedge, the locking wedge is moved faster into the locking position and the overall closing time is shortened as a result.
  • the locking wedge can be closed to take up the ready-to-fire position.
  • Ice on the bottom piece of the unlockable handle represents a secure fixation of the swiveling end of the hand opener lever, which is particularly advantageous during the automatic operation, a stable storage.
  • a hand opener lever 1 is shown as a hollow body 2 rotatable about an opening shaft 5, the interior 3 of which receives a piston-cylinder unit 4.
  • the piston-cylinder unit 4 is pivotally arranged with its cylinder 15 by means of fastening means 17 in the hollow body 2, while the end 18 of the piston 16 protruding from the piston-cylinder unit 4 of the piston 16, which is displaceable in its longitudinal axis, is pivotably connected by means of fastening means 17 to a lever 6 seated firmly on the opening shaft 5.
  • Preloadable springs 7 are arranged within the piston-cylinder unit 4, which are relaxed during the assumption of the starting position 11 and pretensioned when the end position 8 is assumed.
  • the lever 6 rests against a system designed as a stop surface 19 on the hand opener lever. Via the opening lever 10, the locking wedge 9 can be opened and closed during the changing rotational movement of the opening shaft 5.
  • the lever 6 located in the opening 14 of the hand opener lever 1, pivoted about the axis 20 of the opener shaft 5 in the end position 8, can be swiveled up by the hand opener lever 1, which is unlocked by a displaceable handle 22 from its rest position 12 on the base piece 23 by means of an engaging locking bolt 21 be pivoted back into the starting position 11.
  • Figure 2 illustrates the arrangement of the thrust lever 24 on the opener shaft 5 mounted in the base piece 23, the representation of the bearing of the lever 6 and the manual opener lever 1 and the piston-cylinder unit 4 connected to the lever 6 by means of fastening means 17 with the opening shaft 5 a fixed connection incoming opening lever 10 a form fit.
  • FIG. 3 shows the locked position of the hand opener lever 1, in the handle 22 a positive connection with the locking fork 25 arranged on the base piece 23 is established. By moving the longitudinally displaceable handle 22, it can be unlocked.
  • the hand release lever 1 designed as a 'hollow body 2' has assumed a cross-sectional profile of a tube 13 which corresponds to these parameters, as illustrated in FIG.
  • the closing movement of the locking wedge 9 takes place via the tensioned piston-cylinder unit 4, the lever 6 and the opening lever 10, and from the beginning, in a certain range of movement, an equally large torque acts on the opening lever 10 for the movement of the locking wedge 9.
  • the wedge 9 is opened automatically during the pipe advance. While the hand opener lever 1 remains locked in its rest position 12 on the base piece 23, the opening shaft 5 is rotated via the start lever 24 and the closing wedge 9 is opened by the transmission of the rotary movement to the opening lever 10 engaging in the locking wedge 9. By rotating the opening shaft 5 and moving the lever 6 from the initial position 11 into the end position 8, the springs 7 are pretensioned during the longitudinal movement of the piston 18.
  • a locking wedge 9 is difficult to close, or if it remains stuck between the end position 8 and the starting position 11 of the lever 6, the lock can still be closed by hand in that the The hand release lever 1 is unlocked by the handle 22 and swung up until the stop surface 19 abuts the lever 6, and a rigid connection of the hand release lever 1 with the lever 6 can be established by engaging the locking bolt 21.
  • the locking wedge 9 is closed via the opener shaft 5 and the opener lever 10. Because the lever 6 and the piston 16 do not change their position relative to one another during this movement process, no additional forces occur by the springs 7 when closing by hand.
