FIG. 7 shows the embodiment according to FIG. 6 when the support member is attached to the mortar shell by a flexible part.

  FIG. 1 schematically shows a mortar 1 supported in a weapon barrel 2 by a support member 6 according to an embodiment of the invention.

  The mortar 1 is arranged in a barrel 2 of a rear-mounted weapon. Inside, a mortar with a substantially smooth inner surface of the barrel 2 may be used. The rear part of the mortar shell 1 includes a tail tube 3 and a tail portion 4. The tail 4 includes one or typically a plurality of guide vanes 5 for influencing the trajectory of the mortar shell 1. The tail part which comprises the mortar shell 1 may leave | separate from the structure shown by the figure. For clarity, the tail and other tails of the weapon are not shown.

  A support member 6 according to the invention is attached to the tail 4 to keep the mortar shell 1 in place in the barrel 2 until fired. The outer casing 12 of the support element 8 forming part of the support member 6 is sized such that at least a part of the tail 4 of the mortar shell 1 can be positioned therein. The end flange 7 of the support member 6 prevents the mortar shell 1 from moving forward in the barrel 2 when the barrel 2 is oriented horizontally and even when the barrel 2 is oriented downward. The support member 6 is large enough to withstand not only the load due to the mortar shell 1 but also any force caused by vibration or acceleration. The support element 8 further comprises connecting means 10 for attaching the mortar shell 1 to the support member 6.

  The connecting means 10 may be attached to the support element 8, preferably in a selectively openable / closable manner, for example by a screw connection or another mechanical connection. The connecting means 10 may also be attached to the support element 8 in a fixed manner.

  FIG. 2 schematically shows an embodiment according to the invention in which the connecting means 10 provided in the support element 8 includes a spring ring 13. The spring ring 13 is formed in such a way that it can receive the tail 4 of the mortar shell. According to FIG. 2, the spring ring 13 is formed so that it can particularly receive the end of the tail tube 3 of the tail 4 away from the mortar shell 1. The spring ring 13 forms an opening so that the end of the tail tube 3 is placed. The opening of the spring ring 13 is provided so that when the tail tube 3 is placed in the opening, the spring ring 13 generates pressure and directs the spring force to the outer edge or outer surface 14 of the tail tube 3, ie the tail of the mortar shell. The force attaches the mortar shell 1 to the support member 6. That is, the spring ring 13 functions as a flexible element for directing the spring force to the tail 4 of the mortar shell 1 for attaching the mortar shell 1 to the support member 6.

  The spring ring 13 may include a slot arranged to receive a guide vane 5 that forms part of the tail 4 of the mortar shell 1. The slot allows the end of the tail tube 3 to be placed against the bottom of the support element 8. In addition, the spring ring 13 can be easily pressed into the opening demarcated by the spring ring 13 but is much more than pulling it out so that the bond does not open before firing. It has a shape that requires a strong force. According to FIG. 2, the spring ring 13 directs the spring force toward the outer edge 14 of the mortar tail 4 in the region between the guide blades 5. Between the slot or other corresponding opening, a claw-like spring member 18 or other corresponding tongue-like plastic part extends in the spring ring 13 when that part receives the tail 4 of the mortar shell. Bend. That is, the opening of the spring ring 13 is smaller than the diameter of the tail portion 3 of the mortar shell 1, and when the tail tube 3 is inserted into the spring ring 13, the spring member so that the opening of the spring ring 13 increases in size. 18 turns. At the same time, as shown in FIG. 2, the spring member 18 is pressed to apply a spring force to the outer edge 14 of the tail tube 3 of the tail 4 of the mortar shell 1 disposed in the opening 14. Furthermore, according to FIG. 2, these spring members 18 are shaped such that their ends bend towards the bottom of the support element 8, and the tail 4 of the mortar shell is simply arranged in the spring ring 13. However, removing the mortar shell 1 from the spring ring 13 due to the effect of the generated spring force requires a much greater force.

  As shown in FIG. 3, in another embodiment of the spring ring 13, the slot may be provided to bend when receiving the guide vane 5 and be pressed to direct the spring force toward the guide vane 5. That is, when receiving the guide blade 5, the slot is opened and the spring force is directed to the surface of the guide blade 5 in the direction of the vertical axis of the mortar shell 1. Even in this case, the tail 4 of the mortar shell can be easily placed in the spring ring 13, but removing the mortar shell 1 from the spring ring 13 by the generated spring force requires a much greater force. The shape may be as follows. In this way, the slot of the spring ring 13 receives the guide vane 5 quite easily, but at the same time, the spring ring 13 applies a spring force to the guide vane 5, so that removing the mortar shell 1 from the spring ring 13 is quite Need more power.

  Further, in another embodiment, the spring ring 13 may be provided so as to combine the above-described embodiments. In this case, disposing the tail tube 3 in the opening of the spring ring 13 At the same time that the spring force toward the outer surface 14 of 4 is generated, disposing the guide member 5 in the slot 16 generates a spring force toward the guide blade 5. With reference to the above, the spring ring 13 can be of any ring type that can generate a spring force directed to the tail 4 of the mortar shell 1 when receiving a portion of the tail 4 of the mortar shell 1. It should be noted.

  FIG. 4 shows another embodiment of the invention in which the connecting means includes one or more laminate rings 20. In the embodiment of FIG. 4, the connecting means of the support member 8 includes a mounting sleeve 21 and an extension sleeve 23 coupled thereto. The attachment sleeve 21 may be attached to the support member 8 by, for example, screws, fixing means, or other mechanical means. In FIG. 4, two laminate rings 20 are arranged in a space in the extension sleeve 23. One or more support plates or base plates may be arranged between the laminate rings, on the front side and / or on the rear side (not shown). The diameter of the hole in the extension sleeve 23 is such that the extension sleeve 23 can receive the tail tube 3 of the mortar shell 1 or the head 25 of the tail tube. One embodiment of the laminate ring 20 is shown in FIG. The diameter of the opening 24 of the laminate ring 20 in the extension sleeve 23 is at least slightly smaller than the outer diameter of the tail tube 3 of the mortar shell 1 or the outer diameter of the head 25. Thus, when the mortar shell 1 is inserted into the support member 8, the laminate ring 20, particularly the thin plate 22 thereof, bends, and the mortar shell 1 is attached to the support member 8 on the tail tube 3 or the head 25 of the mortar shell 1. The spring force to attach is suitable. The diameter of the opening of the support plate and the base plate substantially corresponds to the outer diameter of the tail tube 3 of the mortar shell 1 or the outer diameter of the head 25, and applies no resistance or force to the mortar shell.

The flexible part 30 is arranged to receive the counter part 32 and the flexible part 30 is bent and the spring force is directed to attach the mortar shell 1 to the support member 6 to the received counter part. In the case of FIG. 6, the flexible part is a connecting part 30 such as a sleeve that bends in a direction transverse to its longitudinal axis when receiving the counterpart 32. The counter part 32 is provided in the tail part 4 of the mortar shell, and in particular, as shown in FIG. In this embodiment, the connecting part 30 consists of a plurality of flexible claw-like parts arranged in a circular arc arch that provides a connecting part such as a sleeve.

  In the embodiment of FIG. 7, a connecting part 30 such as a sleeve receives a counterpart 32 therein. The counterpart 32 includes a conical opening away from the mortar tail 4. This cone makes it easy to place the mortar shell 1 accurately in the support member 6. Further, the cone of the counter part 32 is pressed against the inner wall of the connecting part 30 such as a sleeve so that the counter part 32 is arranged in the connecting part 30. By pressing and bending, the connecting portion 30 is pressed, and at the same time, the spring force is directed to the outer surface of the counter part 32 disposed inside the support member 6 in order to attach the mortar shell. In order to achieve the above, when the counter part 32 is sized such that the outer diameter thereof is at least partially larger than the inner diameter of the connecting part 30, and the counter part 32 is disposed inside, the connecting part 30. A force is applied to make a bend. In a preferred embodiment, the connecting part 30 is inserted into the counter part 32 so that the upper surface of the connecting part 30 passes through the cone of the connecting part 32. And the connection part 30 like a sleeve is firmly arrange | positioned inside the counter part 32, and it becomes difficult to remove | deviate. The conical shape of the counterpart 32 also allows the counterpart to be fitted into the connecting portion 30 and prevent the mortar shell from being easily removed from the support member 8, as shown in FIG.

  The counterpart 32 is provided at the end of the tail tube 3 of the tail 4 of the mortar shell, in which case it is the extension of the tail tube 3 or part of the tail tube. In another embodiment, the counterpart 32 may simply be the end of the hollow tail tube 3, which forms the counterpart 32.

  The spring force directed by the coupling part 30 to the counterpart 32 can also be increased by one or more spring elements (not shown) mounted in the coupling part. The spring element may be a plurality of separate springs arranged on the outer surface of the connecting part 30, or alternatively, a single spring may be arranged around the outer edge of the connecting part 30. Further, the counter part 32 may be provided so as to be arranged around the connecting part 30, and the spring force of the flexible connecting part 30 is directed to the inner surface of the counter part 32. The counterpart 32 may be the head 25 of the tail 4 of the mortar shell 1.

  With reference to the above, both the spring ring that receives the tail of the mortar shell, or a part of its interior, and the flexible connection that receives the counterpart provided around the tail, can be shaped in several ways. It should be noted that it may be modified. That is, for the present invention, it is essential that the mortar shell can be attached to the support member by a spring force. The spring force is generated by a flexible part provided in the support element and arranged to bend when the mortar shell is attached to the support member. It should also be noted that in some cases the mortar shell can be attached to the support member 8 according to more than one embodiment described above.

  As the technology progresses, it will be apparent to those skilled in the art that the basic concepts of the present invention can be implemented in multiple ways. For this reason, this invention and its embodiment are not limited to said example, You may change within the range of a claim.
