Abstract
Pour stabiliser un bouclier à couteaux, et en particulier un bouclier de petites dimensions et à sole ouverte, des plaques d'ancrage (6) pouvant etre soulevées et abaisées sont montées selon l'invention sur les couteaux de sole (2), dans des guides (10) qui supportent sur leur bord inférieur étroit des crampons ou analogues (8) pouvant etre enfoncés dans la sole (3). Les plaques d'ancrage sont en position dressée et disposées de préférence sur les surfaces internes des couteaux de sole. Des dispositifs de pression (15) sont alors disposés sur une partie du cadre du bouclier à couteaux, et de préférence sur un cadre de poussée de ce dernier, sur sont coté intérieur, de manière à agir par le dessus et par l'intermédiaire d'une surface de glissement (14) sur les plaques d'ancrage.To stabilize a knife shield, and in particular a shield of small dimensions and with open sole, anchor plates (6) which can be raised and lowered are mounted according to the invention on the sole knives (2) guides (10) which support on their narrow lower edge crampons or the like (8) which can be inserted into the sole (3). The anchor plates are in the upright position and preferably placed on the internal surfaces of the floor knives.
