ABSTRACT:
FIELD OF INVENTION
The present invention relates to providing a standard automobile jack with a dolly having a plurality of wheels each of which is rotatable around its central axis. Thus, an automobile jack becomes movable with far less effort.
BACKGROUND OF THE INVENTION
The standard automobile floor jack has a rectangular frame supporting a front axle. The axle supports a pair of wheels which provide a range of rolling motion on the forward and rearward directions. The rear of the frame has a left and a right brace each of which supports a caster type wheel to provide a range of motion of 360° for the rear of the frame. However, if the front of the frame needs to be moved sidewards, then the front wheels must be slid sidewards. Such a sidewards motion requires overcoming the static friction of the wheels against the ground surface. The existence of a grate or a gravel or a rough surface would prohibit the sidewards motion of the front end of the frame. The user would have to push the front end sidewards if he could. But if the front end was located under the automobile, then pushing sidewards on the front end could be impossible. The user could try to jerk the entire frame back and forth to reach the desired location for the front end. If a user wishes to load multiple all terrain vehicles sideways in the bed of a pickup, then sliding the front wheels of the floor jack dolly is necessary. A better solution is needed.
The present invention provides a simple chassis for the front end of the jack to rest on. The chassis has a pair of caster type wheels as well as a rear leg which has a caster type wheel. The user can hold the jack handle and easily move the front of the jack in a 360° range of motion using the chassis caster type wheels. A special brace can support an all terrain vehicle. Thus, rotating an all terrain vehicle in the bed of a pickup can be done by one person.
SUMMARY OF THE INVENTION
The main aspect of the present invention is to provide a chassis to hold up the front end of a jack so as to allow a 360° range of motion for the front end of the jack via the use of caster wheels on the chassis.
Another aspect of the present invention is to provide a brace to support an all terrain vehicle.
A rectangular chassis has a dugout running lengthwise to hold the front end of an automobile jack. The jack's front wheels sit in the dugout, wherein ridges of the dugout secure the jack wheels in place. A rearward projecting leg has a rod to secure the body of the jack. The end of the leg as well as each end of the rectangular chassis has a caster type wheel. The rectangular chassis carrying the front end of the jack can be easily moved in a 360° range of motion. A pair of braces set at a 90° angle provide a support brace for an all terrain vehicle.
Other aspects of this invention will appear from the following description and appended claims, reference being made to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.
