VEHICLE WITH INTEGRAL TIRE JACKS
First Claim
1. A pneumatic jack system adapted for mounting on an automobile, comprising:
- at least one pneumatic jack adapted for being integrally mounted beneath an automobile adjacent at least one wheel thereof, the at least one pneumatic jack having a housing and a piston extendable from the housing, the piston having opposed upper and lower ends and a foot attached to the lower end thereof, the housing having at least one first recess and at least one second recess defined in an inner surface thereof, the at least one first recess and the at least one second recess being diametrically opposed with respect to one another;
a pneumatic pump adapted for mounting beneath the automobile for providing compressed air;
at least one hose line connected between the pneumatic pump and the at least one pneumatic jack;
a control system having means for controlling the pneumatic pump to provide pneumatic fluid to the at least one pneumatic jack via the at least one hose line, so that the piston of the at least one pneumatic jack is extendable from beneath the automobile upon receiving compressed air from the pneumatic pump for a distance sufficient to engage a ground surface and raise the at least one wheel adjacent the at least one pneumatic jack above the ground surface; and
first and second stop members mounted to the upper end of the piston, each of the first and second stop members being spring-biased and respectively alignable with the at least one first recess and the at least one second recess defined in the inner surface of the housing, so that when the piston is in an extended state, each of the first and second stop members resiliently and releasably engages the at least one first recess and the at least one second recess, respectively, to releasably maintain the piston in the extended state with respect to the housing.

Abstract
The vehicle with integral tire jacks is an automatic built-in system for lifting a vehicle in the event of a flat tire when the tire requires replacement. The system includes four jacks installed under the vehicle near each wheel. An air compressor activated and controlled by an internal control panel will provide pressure to the jacks, the control panel being provided with knobs and buttons enabling the control of a desired jack. Each jack is adapted for being integrally mounted beneath the automobile, adjacent at least one wheel thereof. The jack includes a housing and a piston extendable from the housing. The piston has opposed upper and lower ends and a foot attached to the lower end thereof.

11. A pneumatic jack system adapted for mounting on an automobile, comprising:
-
at least one pneumatic jack adapted for being integrally mounted beneath an automobile adjacent at least one wheel thereof, the at least one pneumatic jack having a housing and a piston extendable from the housing, the piston having opposed upper and lower ends and a foot attached to the lower end, the housing having upper and lower portions telescopically joined to one another with the lower portion telescoping from the upper portion; a pneumatic pump adapted for mounting beneath the automobile for providing compressed air; at least one hose line connected between the pneumatic pump and the at least one pneumatic jack; a control system having means for controlling the pneumatic pump to provide pneumatic fluid to the at least one pneumatic jack via the at least one hose line, the piston of the at least one pneumatic jack being extendable from beneath the automobile upon receiving compressed air from the pneumatic pump for a distance sufficient to engage a ground surface and raise the at least one wheel adjacent the at least one pneumatic jack above the ground surface; a first set of spring-biased stop members mounted adjacent an upper end of the lower portion of the housing, so that when the lower portion is an extended state with respect to the upper portion of the housing, the first set of stop members resiliently engages a lower annular wall of the upper portion to releasably maintain the lower portion in the extended state with respect to the upper portion of the housing; and a second set of spring-biased stop members mounted adjacent the upper end of the piston, so that when the piston is in an extended state with respect to the lower portion of the housing, the second set of stop members resiliently engages a lower annular wall of the lower portion to releasably maintain the piston in the extended state with respect to the lower portion of the housing. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A pneumatic jack system adapted for mounting on an automobile, comprising:
-
at least one pneumatic jack adapted for being integrally mounted beneath an automobile adjacent at least one wheel thereof, the at least one pneumatic jack having a housing and a piston extendable from the housing, the piston having opposed upper and lower ends and a foot attached to the lower end thereof; at least one support bar having opposed fixed and free ends, the fixed end being pivotally mounted to the housing of the at least one pneumatic jack, so that when the piston extends from the housing, the at least one support bar pivots to extend between the housing and the foot, providing vertical support for the housing; a pneumatic pump adapted for mounting beneath the automobile for providing compressed air; at least one hose line connected between the pneumatic pump and the at least one pneumatic jack; a control system having means for controlling the pneumatic pump to provide pneumatic fluid to the at least one pneumatic jack via the at least one hose line, the piston of the at least one pneumatic jack being extendable from beneath the automobile upon receiving compressed air from the pneumatic pump for a distance sufficient to engage the ground and raise the wheel adjacent the jack above the ground; at least one first spring-biased stop member mounted to the housing adjacent the fixed end of the at least one support bar, so that when the at least one support bar extends between the housing and the foot, the at least one first stop member releasably prevents pivoting of the at least one support bar; and at least one second spring-biased stop member mounted adjacent the upper end of the piston, so that when the piston is in an extended state with respect to the housing, the at least one second stop member resiliently engages a lower annular wall of the housing to releasably maintain the piston in the extended state with respect thereto. - View Dependent Claims (19, 20)
