In a self-loading grenade thrower, the components or cartridges (1, 1') of which are enclosed in each instance by an annular belt member (7), each belt member (7) is provided with bulges (15, 17) lying opposite one another, which are traversed in each case by an opening (11, 11'). The adjacent openings (11, 11') of the two belt members (7) are joined articulately with one another by a connecting member (9) which traverses these openings and has on both ends an enlarged or thickened portion (23, 25) which retains its belt member. To the openings (11, 11') of the two bulges (15, 17) there are assigned two rest paths (13, 13') which are open toward an edge of the belt member (7) and the width of which is such that the connecting member (9) can be released from the opening (11) under gentle bending open or flexing of the corresponding rest path (13) by the axial, mutual shifting of two adjacent cartridges (11, 11", 11"'), regardless of the direction. Preferably the enlarged portions are received untwistably in the bulges and joined with one another by a joint shaft which is articulately bendable about an axis parallel to the cartridges.
Cette invention concerne le chargement automatique d'un lance-grenades. Chaque grenade (1, 1') porte une ceinture annulaire (7) comportant des bourrelets (15, 17) diamétralement opposés qui présentent tous les deux une ouverture (11, 11'). Les ouvertures adjacentes (11, 11') de deux ceintures (7) sont réunies par une articulation (9) qui les traverse et qui comporte aux deux bouts un renflement ou une partie épaissie (23, 25) de retenue. Aux ouvertures (11, 11') des deux bourrelets (15, 17) sont associées deux voies d'évacuation (13, 13') ouvertes vers un côté de la ceinture (7) et présentant une largeur telle que l'articulation (9) peut sortir de l'ouverture (11) lorsque la voie d'évacuation correspondante (13) est légèrement fléchie au déplacement axial relatif de deux grenades adjacentes (11, 11", 11"'), peu importe la direction du déplacement. De préférence, les renflements susmentionnés se logent dans les bourrelets sans possibilité de torsion et sont réunis par un arbre commun articulé autour d'un axe parallèle aux grenades.
