The present invention relates to a variable-geometry stabilizing foot, in particular for earth-moving vehicles, comprising a support member (1) able to rotate about a fulcrum (3) associated with the chassis of a vehicle to be stabilized and an extendable arm (5) slidably mounted on this support member (1) (see Fig. 1). A control linkage (9) is also provided, being hinged with the chassis (2) of the vehicle and with the extendable arm (5) for slidably moving the latter with respect to the support member (1) (see Fig. 2). The extendable arm (5) is provided at the bottom end with a support foot (8) able to perform vertical displacements when actuating means (13) move said support member (1) between a recovery position (15) and an operative position (16) (see Fig. 3). In the recovery position (15) the stabilizing foot is thus arranged so as to be retracted and take up little space on the chassis (2) of the vehicle, while in the operative position (16), the stabilizing foot is rotated through an angle (.alpha.) towards the ground with respect to the recovery position (15). The chassis (2) of the vehicle also comprises a shaped member (14) designed to receive in abutment the support foot (8) and rotate it towards the chassis (2) when the support member (1) is brought into the recovery position (15).

Béquille de stabilisation à géométrie variable, destinée en particulier aux véhicules de terrassement, comprenant un élément d'appui (1) articulé sur un pivot (3) associé au châssis du véhicule que l'on souhaite stabiliser et un bras télescopique (5) pouvant glisser le long de cet élément d'appui (1) (voir Fig. 1). Cette invention porte également sur une timonerie (9), articulée au châssis (2) du véhicule et au bras télescopique (5) pour que ce dernier puisse glisser par rapport à l'élément d'appui (1) (voir Fig. 2). Le bras télescopique (5) se trouve au niveau de l'extrémité inférieure et comporte une béquille d'appui (8) capable d'effectuer des déplacements verticaux lorsqu'un moyen d'actionnement (13) déplace le dit élément d'appui (1) de la position rentrée (15) à la position déployée (16) (voir Fig. 3). Dans la position rentrée (15), la béquille de stabilisation est repliée de manière à occuper peu de place sur le châssis (2) du véhicule, alors que, dans la position déployée (16), la béquille de stabilisation pivote selon un angle (.alpha.) vers le sol par rapport à la position rentrée (15). Le châssis (2) du véhicule comporte également un profilé (14) conçu pour que la béquille (8) s'accote sur lui et pour qu'il la fasse tourner vers le châssis (2) lorsque l'élément d'appui (1) est en position rentrée (15).
