Abstract

Cartridge ammunition 1 for a grenade pistol includes a casing 10 made, for example, of plastic, the casing having an opening. A projectile 11 disposed in the casing opening and includes a tracer charge and/or delayed-action charge 11b. A primer 13 and a propelling charge 14 the disposed in a cup 12 at the base of casing 10. The cup 12 is composed of two mutually concentric sleeves 12a, and 12b, with the inner sleeve 12b being mounted so as to be slidable in the outer sleeve 12a and extendable in the manner of a telescope. The outer sleeve 12a has a free end section which is provided, with an external thread 100 followed by an annular, predetermined, circumferential break location 12d. The base of projectile 11 includes a sleeve 17 provided with an internal thread which can be screwed onto the outer sleeve 12a of cup 12. A firing channel 12c is provided in the bottom or end wall 12e of the cup-shaped inner sleeve 12b, with such firing channel being oriented toward the tracer and/or delayed-action charge 11b. The result of this construction is that the ammunition can be assembled easily, and an almost constant initial velocity can be maintained despite fluctuating environmental conditions.

Claims

1. Cartridged ammunition for a grenade pistol, comprising:

a cartridge casing having a base and an opening;

a projectile disposed in the casing opening, the projectile including a base with a connecting thread, a payload, and at least one charge;

primer and propelling charges; and

a cup at the base of the casing, the primer and propelling charges being disposed in the cup, the cup including a sleeve and means for providing a firing channel oriented toward the at least one charge included in the projectile, wherein the sleeve has a free end section with an external thread followed by an annular, circumferential predetermined break location, and wherein the sleeve is fastened to the base of the projectile by way of the connecting thread.

2. The cartridged ammunition of claim 1, wherein the casing is made of plastic.

3. The cartridged ammunition of claim 1, wherein the at least one charge included in the projectile comprises a tracer charge.

4. The cartridged ammunition of claim 1, wherein the at least one charge included in the projectile comprises a delayed-action charge.

5. The cartridged ammunition of claim 1, wherein the at least one charge included in the projectile comprises a tracer charge and a delayed action charge.

6. The cartridged ammunition of claim 1, wherein the sleeve has an opening which is disposed between the base of the casing and the base of the projectile.

7. The cartridged ammunition of claim 6, wherein the opening is disposed adjacent the break location.

8. The cartridged ammunition of claim 6, wherein the opening is disposed at the break location.

9. The cartridged ammunition of claim 6, further comprising means for closing the opening.

10. Cartridged ammunition for a grenade pistol, comprising:

a casing having an opening and a base;

a projectile disposed in the opening of the casing, the projectile including a payload, a base portion having a threaded region, a transfer charge, and means for supporting the transfer charge adjacent the base of the projectile and adjacent the payload, with the transfer charge communicating with the payload;

primer and propelling charges; and

cup means disposed at the base of the casing for accommodating the primer and propelling charges and for providing a firing channel between the propelling charge and the transfer charge, the cup means including

a sleeve having a first end and having a second end which is mounted at the base of the casing, the sleeve additionally having a threaded region adjacent the first end and having an annular break location between the second end and the threaded region, the threaded region of the sleeve being screwed to the threaded region of the base portion of the projectile.

11. Cartridged ammunition according to claim 19, wherein the sleeve has at least one opening disposed between the first and second ends thereof.

12. Cartridged ammunition according to claim 11, wherein the sleeve has a plurality of openings which are arranged at uniform spacing in an annular pattern.

13. Cartridged ammunition according to claim 12, wherein the openings are circular, and have diameters ranging from about 0.5 mm to about 2.5 mm.

14. Cartridged ammunition according to claim 11, further comprising means for covering the at least one opening.

15. Cartridged ammunition according to claim 10, wherein the sleeve is cylindrical and has an annular groove which provides the annular break location.

16. Cartridged ammunition according to claim 15, wherein the sleeve additionally has at least one opening which lies in the groove.

17. Cartridged ammunition according to claim 15, wherein the sleeve additionally has at least one opening which lies adjacent the groove.

18. Cartridged ammunition according to claim 10, wherein the casing is made of plastic, and wherein the sleeve has at least one opening disposed between the first and second ends thereof.

19. Cartridged ammunition according to claim 15, wherein the casing is made of metal, and wherein the sleeve additionally has at least one opening which lies in the groove.

20. Cartridged ammunition according to claim 15, wherein the casing is made of metal, and wherein the sleeve additionally has at least one opening which lies adjacent the groove.
