An airburst hand grenade constructed so as to jump 1-2 m above the ground before detonating. The hand grenade includes a detonator, a warhead, and support legs for raising the hand grenade from a horizontal position to an upright position once it has landed after being thrown. The detonator includes a delay unit, an upper charge which releases the support legs, a jump charge which propels the warhead into the air, and an explosive cartridge which initiates a main charge. Because the grenade detonates above ground, the fragments are spread essentially horizontally and at an angle to the ground and consequently attack the target from above, which results in a much larger target surface and the capability of spreading fragments behind a shelter.

The invention claimed is: 1. A hand-throwable grenade comprising a detonator initiating mechanism that is activated by an operator before said hand grenade is thrown, a detonator, a warhead having a main charge, a device constituting part of said hand grenade for raising the hand grenade from a horizontal position to an upright position after said hand grenade has been thrown and has landed, and a jump assembly operable with said detonator for propelling the warhead into the air from said upright position for mid-air explosion thereof. 2. The hand grenade as claimed in claim 1, wherein the detonator is thrown into the air with the warhead to initiate the main charge. 3. The hand grenade as claimed in claim 1, wherein the device for raising the hand grenade from the horizontal position to the upright position includes support legs arranged round the hand grenade in a spring leg mounting and held in an upright position against a body of said hand grenade by a locking cover prior to deployment. 4. The hand grenade as claimed in claim 3, wherein the detonator includes a pyrotechnic charge for removing the locking cover to release the support legs. 5. The hand grenade as claimed in claim 1, wherein the detonator includes a jump charge operable with said jump assembly to propel the warhead into the air. 6. The hand grenade as claimed in claim 5, wherein the jump assembly includes a guide tube movingly arranged in a duct in the warhead and configured, upon detonation of said jump charge, to guide the warhead in an upward direction. 7. The hand grenade as claimed in claim 6, wherein the guide tube is configured to guide the warhead in said upward direction by rotating the warhead. 8. The hand grenade as claimed in claim 1, wherein the hand grenade includes a safety device configured to prevent an explosive cartridge of the detonator from initiating the main charge. 9. The hand grenade as claimed in claim 8, wherein the safety device includes a guide tube of said lump assembly, said guide tube being arranged between the explosive cartridge of said detonator and the main charge. 10. The hand grenade as claimed in claim 1, wherein the hand grenade jump assembly includes a base plate frictionally engaged against the ground to allow controlled propelling of the warhead into the air. 11. The hand grenade as claimed in claim 1, wherein the detonator includes a delay unit, an upper charge for enabling said device to raise the hand grenade to said upright position, a jump charge capable of propelling the warhead above the ground, and an explosive cartridge capable of initiating the main charge. 12. The hand grenade as claimed in claim 11, wherein the delay unit is a pyrotechnic delay unit or an electrical delay device. 13. The hand grenade as claimed in claim 1, wherein the warhead includes an axial duct, and the jump assembly includes a guide tube slidably arranged in said duct. 14. The hand grenade as claimed in claim 1, wherein the device for raising the hand grenade includes two or more support legs articulated to a spring leg mounting, said support legs being resiliently raised to an upright position along the warhead and held in said upright position by a locking cover. 15. The hand grenade as claimed in claim 14, wherein the lump assembly includes a guide tube and a base plate releasably arranged on the spring leg mounting, said base plate frictionally engaged with the around and said guide tube movably arranged in said warhead. 16. The hand grenade as claimed in claim 6, wherein the guide tube includes an upper end surface on which combustion gases of the jump charge act to propel the warhead into the air. 17. The hand grenade as claimed in claim 15, wherein the hand grenade can be made to burst resting on the ground by manually removing the guide tube and/or the base plate. 18. A hand grenade comprising: a detonator having a pyrotechnic charge and a jump charge; a warhead having a guide element movably arranged therein; spring members for raising the hand grenade from a horizontal position to an upright position, said spring members being held at a base of said grenade in a spring leg mounting and fixed to a top of said grenade by a locking cover; said pyrotechnic charge, upon detonation, forcing the locking cover upward to release said spring members to raise said hand grenade to the upright position; and said jump charge, upon detonation and in conjunction with said guide element, for propelling the warhead into the air before it bursts. 19. The hand grenade as claimed in claim 18, wherein said detonator further comprises an explosive cartridge capable of initiating a main charge of said warhead. 20. The hand grenade as claimed in claim 19, wherein said guide element is arranged between the explosive cartridge and the main charge and prevents detonation of said main charge until said guide element is removed from said warhead by detonation of said jump charge or by manual removal. 21. A hand grenade comprising: a mechanism for initiating the hand grenade; a detonator; a warhead having a main charge and a movable guide element operable with said detonator to propel the warhead into the air before said main charge is detonated; releasable members for raising the hand grenade from a horizontal position to an upright position after said grenade has been deployed, said members being secured adjacent an outer part of said warhead by a locking cover prior to said deployment; said detonator including a delay unit, a first charge capable of releasing said members by removing said locking cover, a second charge operable with said guide element to propel said warhead into the air for mid-air explosion thereof, and an explosive cartridge for initiating the main charge. 22. The hand grenade as claimed in claim 21, wherein the delay unit is a pyrotechnic delay unit or an electrical delay device.
