Abstract
Abstract A stabilizer for land vehicles, such as recreational motor homes, is provided for jacking the vehicle to a position at least partially lifting the weight of the vehicle off its supporting springs so that movement of persons within the vehicle will not result in rocking of the vehicle. The stabilizer comprises a pivotally supported pair of legs at the front and rear of the vehicle, each leg pivotally supporting at its free end a foot. Springs bias the legs into raised position and power operated means lower the legs into vehicle lifting position. The pivotal articulation between the legs and the feet includes slots to accommodate vehicle lifting and lowering movement of the legs without dragging the feet on the ground, and springs interconnecting the legs and the feet bias the feet into a position relative to the legs such that the foot is held flat against the leg with the outer ends of the slots drawn against the pivot.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
202 words
A stabilizer for lifting a vehicle and stationarily supporting it which comprises: a leg member pivotally attached to the underside of the vehicle; means for holding the leg member in raised position beneath the vehicle; a foot member pivotally carried by the leg member at the free end thereof; the pivotal mounting of the foot member on the leg member including a capability of translational relative movement between the foot member and the leg member enabling the leg member to move relative to the foot member while the latter remains stationary, comprising a pivot pin carried by the leg member for pivotally supporting the foot member and the foot member having a slot extending in a direction parallel to its sole to receive the pivot pin and accommodate movement of the leg member relative to the foot member while the foot member has its sole pressed against the stabilizing surface; means for moving the leg member pivotally downward to first bring the foot member into contact with the ground and then to lift the vehicle; and yieldable means urging said foot member to seek a position folded against said leg member with an end of the slot drawn against the pivot pin.
Claim 2
Dependent Claim
202 words
A stabilizer for lifting a vehicle and stationarily supporting it which comprises: a leg member pivotally attached to the underside of the vehicle; means for holding the leg member in raised position beneath the vehicle; a foot member pivotally carried by the leg member at the free end thereof; the pivotal mounting of the foot member on the leg member including a capability of translational relative movement between the foot member and the leg member enabling the leg member to move relative to the foot member while the latter remains stationary, comprising a pivot pin carried by the leg member for pivotally supporting the foot member and the foot member having a slot extending in a direction parallel to its sole to receive the pivot pin and accommodate movement of the leg member relative to the foot member while the foot member has its sole pressed against the stabilizing surface; means for moving the leg member pivotally downward to first bring the foot member into contact with the ground and then to lift the vehicle; and yieldable means urging said foot member to seek a position folded against said leg member with an end of the slot drawn against the pivot pin.
Claim 3
Dependent Claim
197 words
A jack for lifting a vehicle to at least partially relieve the pressure of the vehicle on a cUshioning spring which comprises: a leg member pivotally supported by the vehicle underneath the vehicle; spring means for retracting the leg member upwardly into a position underlying the vehicle; fluid pressure operable means comprising a cylinder and a piston interconnecting the vehicle and the leg member adapted to effect pivotal movement of the leg member away from underlying relation to the vehicle accompanied by an increase in the tension of said spring means; a pivot pin carried by the free end of the leg member; a foot member having a slot serving to articulate the foot member to the pivot pin and enabling the leg member to move relative to the foot member to elevate the vehicle without dragging the foot member after engagement of the foot member with the ground; and a spring interconnecting the foot member and the leg member for retracting the foot member into flat engagement with a side of the leg member and with an end of the slot engaging the pivot pin when the leg member is retracted from the vehicle lifting position.
Claim 4
Dependent Claim
197 words
A jack for lifting a vehicle to at least partially relieve the pressure of the vehicle on a cUshioning spring which comprises: a leg member pivotally supported by the vehicle underneath the vehicle; spring means for retracting the leg member upwardly into a position underlying the vehicle; fluid pressure operable means comprising a cylinder and a piston interconnecting the vehicle and the leg member adapted to effect pivotal movement of the leg member away from underlying relation to the vehicle accompanied by an increase in the tension of said spring means; a pivot pin carried by the free end of the leg member; a foot member having a slot serving to articulate the foot member to the pivot pin and enabling the leg member to move relative to the foot member to elevate the vehicle without dragging the foot member after engagement of the foot member with the ground; and a spring interconnecting the foot member and the leg member for retracting the foot member into flat engagement with a side of the leg member and with an end of the slot engaging the pivot pin when the leg member is retracted from the vehicle lifting position.
Claim 5
Dependent Claim
62 words
A jack in accordance with claim 2 wherein the length of the leg member is such in relation to the extent of pivotal movement imparted by the fluid pressure operable means that the leg member extends obliquely outwardly and downwardly from underneath the vehicle and in addition to elevating the vehicle it acts as a strut imparting lateral stability to the vehicle.
