Abstract
A pair of jack assemblies, each having a longitudinally adjustable body and support foot diagonally coupled to the bottom of the body, are rotationally coupled to a pair of plates mounted to a vehicle. In an operational position, the jack assemblies extend downward to the ground in an outward direction transverse to the longitudinal axis of the vehicle. In a storage position, the jack assemblies are rotated upward to a horizontal position so they extend beyond the sides of the vehicle and then adjusted to decrease their length so the foot engages a portion of the vehicle and prevents downward rotational movement of the jack assembly. The coupling between each jack assembly and the associated mounting plate provides for limiting rotation of the jack assembly between the operational and storage positions.
Claims12
A self-storing vehicle stabilizer adapted for attachment to an elongated, horizontal structural member of a vehicle such as a bumper, comprising:
- a jack assembly having an elongated body of adjustable length;
- a ground engaging foot attached to the extremity of said jack assembly;
- means for rotatably mounting said assembly on the structural member such that said assembly is swingable about an axis extending above the lowermost surface of the structural member on which it is adapted to be mounted, said assembly being swingable between a storage position in which it is generally parallel to the longitudinal axis of the structural member and an operational position in which said foot is adapted to contact the ground;
- said jack assembly being adjustable to a length so that said foot is aligned with the end of the structural member in the storage position, the adjustability being sufficient so that at a first length said foot clears the end of the structural member and at a second length, shorter than said first length, said foot engages the structural member;
- and
- said foot being sized to extend from said jack assembly beyond an edge of the structural member so as to engage the end of the structural member when said assembly is rotated to its storage position and then shortened thereby stabilizing said assembly in said storage position.

A self storing vehicle stabilizer comprising:
- a pair of jack assemblies, each jack assembly having an elongated body of adjustable length and foot means coupled to an extremity of said body and extending laterally outward from said body sufficiently to engage the bumper of the stabilized vehicle when said body is in a storage position, the adjustability being sufficient so that at a first length said foot clears the end of the bumper and at a second length, shorter than said first length, said foot engages the bumper;
- and
- a pair of spaced mounting means, each mounting means rotationally coupling one of said jack assemblies to a vehicle about an axis extending above the lowermost surface of the bumper on which it is mounted, securing said jack assembly in an operational position wherein elongating said jack body results in said foot means engaging a vehicle support surface such as ground, and limiting upward rotational movement of said jack assembly at the storage position wherein sufficiently shortening said jack body results in said foot means engaging the end of the bumper and preventing downward rotational movement of said foot means.
A movable vehicle stabilizer comprising:
- a pair elongated supporting struts of adjustable length each having a first extremity rotationally coupled to a vehicle and a second extremity adapted to engage the vehicle and to engage the ground;
- a foot means coupled to the second extremity of each of said struts, said foot means including a surface extending transversely outward from said struts sufficiently to engage a portion of the vehicle when said struts are in a generally horizontal attitude and sufficiently shortened;
- a pair of mounting plates secured to the bumper of the vehicle so said mounting plate has a major vertical surface, said mounting plate having integral tab extensions protruding toward the vehicle to prevent relative motion between said mounting plate and the bumper;
- said mounting plates rotationally coupling said struts to the vehicle, securing said struts in an operational position wherein elongating said struts results in said foot means engaging the ground, and limiting upward rotational movement of said struts at a storage position wherein sufficiently shortening said struts results in said foot means engaging an extremity of the bumper and preventing downward rotational movement of said foot means;
- a pair of generally planar pivot plates, each plate attached to a strut and substantially parallel to said mounting plate for interfacing between said strut and said mounting plate;
- said pivot plate having a pivot opening for pivotally coupling said pivot plate to said mounting plate, a stop means radially displaced in the plane of the pivot plate from said pivot opening for limiting upward rotation of said pivot plate by engaging said mounting plate, and a securing means radially displaced in the plane of the pivot plate from said pivot opening a distance greater than the displacement of said stop means from said pivot opening for securing said pivot plate to said mounting plate when said strut is in the operational position;
- and
- said mounting plate having a mounting stop means for cooperating with said stop means of said pivot plate to limit upward rotational movement of said strut, a mounting securing means for cooperating with said securing means of said pivot plate to secure said strut in an operational position, and a mounting pivot means for cooperating with said pivot opening of said pivot plate to provide for pivotal rotation of said strut with respect to said mounting plate.
