Description
- This invention relates to a grenade. In particular, a preferred form of the invention relations to a grenade capable of being fired from a suitable rifle.
- In the context of military operations it is desirable to have a grenade which can be fired with a rifle to deliver a pay load of metallic pellets or similar projectiles to a target. Grenades which release pellets at a high velocity in a dispersed fashion are particularly useful for close quarters combat, especially in a jungle situation. It is accordingly an object of at least one form of the present invention to provide a grenade which can be fired to deliver pellets or other projectiles to a target, or to at least provide the public with a useful choice.
- According to one aspect of the invention there is provided a grenade, having a case, a sabot, and a cover;
- the sabot having a base part, a space for receiving a projectile or projectiles, and a plurality of petals;
- the grenade being formed such that when it is arranged for use the sabot is fitted to the case, the projectile or projectiles are within the space, and the cover is fitted around the petals wherein end parts of the petals bend towards one another to substantially encapsulate the projectile or projectiles;
- the grenade being formed such that when it is in use and is fired from a suitable rifle a charge in the case causes the sabot and the projectile or projectiles to be propelled forward and punch through the cover such that the projectile or projectiles are released from the sabot to a target.
- Preferably the petals are arranged such that they fan outwards to release the projectile or projectiles when the grenade has been fired and the sabot leaves the rifle.
- Preferably the sabot is arranged such that it will spin within a barrel of the rifle when the grenade has been fired, the spin causing the petals to fan outwards when they contact air outside the barrel.
- Preferably the sabot has a resilient packing for receiving the projectile or projectiles. The packing may be a pad formed from a suitable micro-cellular material.
- Preferably the cover is substantially conical and has an open end and a closed end, the open end engaging the case, and the closed end defining an extremity (eg nose) of the grenade, when the grenade is in a ready for use arrangement.
- Preferably the cover has a plurality of lines of weakness to assist the sabot and the projectile or projectiles to punch through the cover when the grenade is fired with the rifle. The lines of weakness may be in the form of fractures and/or grooves in the cover.
- Preferably the cover and the case are fitted to one another by way of screw threads when the grenade is in a ready for use arrangement.
- Preferably the case is arranged with an internal space adapted to act as at least part of a low pressure chamber, the low pressure chamber being defined in part by a wall and a floor, the wall and the floor being part of the case, the wall tapering in towards the floor and arranged such that the base part of the sabot can butt against the wall such that the floor and the base part of the sabot are spaced from one another. Preferably the wall merges into the floor in a substantially curved fashion.
- Preferably the base part of the sabot has an obturating edge where it butts against the wall when the grenade is in a ready for use arrangement. This obturating edge facilitates a sealing contact between the sabot and the wall.
- Preferably the case has a high pressure chamber which, when the grenade is in a ready for use arrangement, houses a charge (eg suitable cellulosic explosive material). When the grenade is ready for use the high pressure chamber may be substantially closed by a plug inserted into the rest of the case, the plug containing the charge. The plug which itself forms part of the case and the high pressure chamber, may be screw fitted to the rest of the case.
- Preferably there is a passage or passages between the high pressure chamber and the low pressure chamber.
- Preferably a sheet member, eg a thin disk, is within the high pressure chamber and covers the passage or passages when the grenade is in a ready for use arrangement.
- Preferably the plug has a primer for igniting the charge.
- According to another aspect of the invention there is provided a grenade for firing from a suitable rifle, the grenade having a case and a sabot, the sabot having an obturating edge for contacting the case to form a substantially water tight seal between the case and the sabot.
- According to a further aspect of the invention there is provided a grenade for firing from a suitable rifle, the grenade having a case and a sabot, the case having a high pressure chamber for receiving a charge, the high pressure chamber being substantially closed by a plug, the plug itself being part of the case, the plug having a primer and engaging the rest of the case by way of a screw thread arrangement.
- According to another aspect of the invention there is provided a grenade adapted to be fired from a suitable rifle, the grenade incorporating a case, a sabot, a plurality of projectiles, and a cover, the sabot having a plurality of flexible petals which substantially encapsulate the projectiles while the cover substantially encapsulates the petals and holds the petals against the projectiles.
- Some preferred aspects and embodiments of the invention will now be described by way of example, and/or with reference to the accompanying drawings, of which:
- FIG. 1 is an external side view of a rifle grenade,
- FIG. 2 is an over-head view of the grenade,
- FIG. 3 is an underneath view of the grenade,
- FIG. 4 is cross sectional view of the grenade taken through the line A-A as represented in FIG. 3,
- FIG. 5 is a three dimensional cross-sectional view of the grenade taken through the line A-A,
- FIG. 6 is a three dimensional view of a sabot forming part of the grenade, and
- FIG. 7 is a three dimensional view of the sabot as it would appear when the grenade is in a ready to use arrangement.
- Referring to FIGS.1 to 5, the grenade has a
case 1, asabot 2, and a cover ornose cone 3. Thecase 1 and thenose cone 3 are adapted to engage one another by way of a screw thread arrangement wherein thenose cone 3 screws into thecase 1. Thecase 1 has a cup likeplug 4 which can be screwed into place by way of a screw thread arrangement to define ahigh pressure chamber 5 within thecase 1. Thehigh pressure chamber 5 is adapted to hold a charge of a suitable cellulosic explosive material or similar. As shown, theplug 4 has aprimer 6 for igniting the cellulosic explosive material when the grenade is fired from a rifle. - With reference to FIGS. 4 and 5, the
plug 4 fits up against a 0.5mm copper disc 7, thedisk 7 coveringpassages 8 extending away from thehigh pressure chamber 5. As shown, thepassages 8 extend to alow pressure chamber 9 defined within an internal space of thecase 1. More specifically, thelow pressure chamber 9 is defined by or between awall 10 and afloor 11 of the case, and thebase 12 of thesabot 2. Thebase 12 of the sabot has an obturatingedge 13 which forms a gas-tight seal between thesabot 2 and thecase 1. - Referring to FIG. 6, the
sabot 2 has a plurality ofwad petals 14 extending upwards. Each of the petals are separated byslits 15 so that they can move independently of one another. As shown, each petal has a fixedend 16 and afree end 17. FIG. 6 shows thesabot 2 prior to it assuming a ready for use orientation. - The ready for use orientation of the
sabot 2 is shown at FIGS. 4, 5 and 7, where a plurality of projectiles orpellets 18 are packed between the petals on a resilient foam packing orpad 19. As shown, when ready for use thepetals 14 overlap one another to assume a substantially conical shape, and are held in that orientation by way of thenose cone 3. More specifically, thepetals 14 bend inwards under pressure from thenose cone 3, and substantially encapsulate the pellets. The petals may not completely enclose the pellets as the apex of the conical shape may remain slightly open. However, even in this situation, and for the purposes of this document, the petals should be interpreted as substantially encapsulating the pellets. Thenose cone 3 thus enshrouds both thepetals 2 and thepellets 18 to maintain the petals in the desired orientation. The pellets are held tight and are substantially prevented from rattling within the sabot due to the pressure of the nose cone, and also due to the compressive effect of theresilient pad 19 on the pellets. - The
nose cone 3 is formed with grooves, fracture lines, or other lines of weakness so that it can be readily ruptured when desired. Thenose cone 3 may be formed from a suitable plastics material, for example a suitable polyethylene material. Thesabot 2 is preferably formed from a suitable urethane material, and thecase 1 is primarily formed from a suitable metallic substance. - When the grenade is in use it is loaded into a grenade firing rifle and fired. The charge in the
high pressure chamber 5 detonates, blows through thecopper disc 7, and sends gases through thepassages 8 and into thelow pressure chamber 9. This causes thesabot 2, including thepellets 18, to blast through thenose cone 3 and move down the barrel of the rifle. Thecase 1 is left within the rifle. The sabot is arranged such that as it moves down the barrel it is caused to spin. When thesabot 2 passes out of the end of the barrel, the force of the outside air on the spinningsabot 2, and in particular on thepetals 14, causes thepetals 14 to open or flare outwards thus releasing thepellets 18 at high velocity. Thepellets 18 proceed to a desired target, leaving thesabot 2 behind due to the slowing effect of the outside air on the flaredpetals 14. - The
pellets 18 are preferably lead balls coated with copper, and when fired as above spray outwards making it difficult for a fleeing target to avoid them. In some embodiments of the invention thepellets 18 may be capable of blowing a door off its hinges. - When a grenade is fired as above it will be evident to those skilled in the art that there is a need to protect the barrel of the rifle from damage by the
pellets 18. This protection is achieved by way of thepetals 14, which only open to release thepellets 18 when the sabot has passed out of the end of the barrel. In the embodiment of the invention described above thecase 1 is substantially 40 mm in diameter, although it should be understood that this is not a restriction on the scope of the invention. - While some preferred aspects and embodiments of the invention have been described by way of example, it should be appreciated that modifications and improvements can occur without departing from the scope of the appended claims.
