Patent

CA 2742612

The invention relates to a mortar (1) with at least one barrel (2), which is mounted movably over a ball journal (3) in a supporting device (4) at the bottom, and to an aiming device (5), serving to aim the barrel vertically and horizontally. In order to be able to aim the barrel (2) of the mortar (1) automatically in a simple and cost advantageous manner, the invention proposes that the aiming device (5) preferably comprises a carriage (6), which can be moved along guideways (7) essentially horizontally to the barrel (2) to or away from the latter. At the carriage (6), the first end region (10) of a pivoted arm (13) is mounted so that it can be rotated about a pivot axis (14), the second end region (16) of which is connected with a spherical plain bearing (17), guiding the barrel (2). The spherical plain bearing (17) embraces a housing part (19), which is open at its end faces and in which an inner part (21) is mounted spherically, which contains a cylindrical barrel guide (22), for movably accommodating the barrel (2).

L'invention concerne un mortier (1) qui comprend au moins un canon (2) logé mobile par le biais d'un pivot sphérique (3) dans un dispositif d'appui côté sol (4), ainsi qu'un système de pointage (5) pour le pointage en hauteur et en direction du canon (2). L'invention vise à permettre de manière simple et bon marché un pointage automatique du canon (2) du mortier (1). A cet effet, le système de pointage (5) comprend de préférence un chariot (6) qui peut être approché ou éloigné du canon (2) pratiquement horizontalement le long de glissières de guidage (7). La première zone d'extrémité (10) d'un bras pivotant (13) est montée sur le chariot (6) à pivotement autour d'un axe de pivotement (14) perpendiculaire au plan du chariot (6) et sa deuxième zone d'extrémité (16) est reliée à une articulation à rotule (17) guidant le canon (2). L'articulation à rotule (17) comprend une partie enveloppe (19) ouverte à ses extrémités frontales, dans laquelle un élément interne (21) à logement sphérique contient une glissière tubulaire cylindrique (22) permettant la réception mobile du canon (2).
