Full Description:
[0001]    This application claims the priority benefit under 35 U.S.C. section 119 of U.S. Provisional Patent Application No. 61/857,970 entitled “Trailer Jack Stand Support” filed on Jul. 24, 2013; which is in its entirety herein incorporated by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates to a device for stabilizing a trailer jack on hard or soft ground after the trailer has been disconnected from its towing vehicle, and more particularly to a stabilizing device that can receive a wheel, a jack pad or the shaft of a jack. The present invention also relates to a safety stand of substantially fixed height of such character that it can be used to support house trailers when they are parked, the drawbar end of trailers in general or, in fact, any relatively stationary and appreciably heavy weight which needs a relatively stable support. 
       BACKGROUND OF INVENTION 
       [0003]    Various stands have been available ranging from mere blocks of wood or concrete to somewhat complicated adjustable stands which can be elevated and lowered by employment of a crank with a rack and pinion. Blocks are not always acceptable because of their weight and bulk, especially when it might be advantageous to move them together with the vehicle. Adjustable-type stands often are not stable enough to be dependable and, when constructed in a stable fashion, are frequently unnecessarily expensive. They also have the disadvantage of not being readily stowed. 
         [0004]    In setting up a mobile home trailer, a manufactured building or other similar structures and objects, the structure must be blocked and supported. One simple method employed for blocking the structure is to use a plurality of concrete blocks stacked up on top of each other. As each concrete block has a limited footprint, each block stack has a limited weight capacity with respect to the ground. Therefore, in order to support modern structures, wherein several thousand pounds must typically be supported, two or more side by side block stacks must be established. Not only is a series of concrete block stacks aesthetically unpleasant, the need to bring a large number of concrete blocks to the job sight is expensive and labor intensive. Additionally, a relatively high concrete block stack may tend to be unstable under various loads and environmental conditions. 
         [0005]    In order to overcome the problems of using only concrete blocks to support a structure various devices have been proposed. Such devices, although working with varying degrees of efficiency, tend to be difficult to use and maintain and are unduly heavy ad bulky. 
         [0006]    Therefore, there is a need in the art for a structure support stand that addresses the above-stated problems in the art. Such a device must be capable of supporting several thousand pounds and must not be an eye sore. Such a device must be relatively lightweight and easy to transport, assemble and use. Ideally, such a device will be relatively inexpensive to manufacture and maintain. 
       OBJECTS OF THE INVENTION 
       [0007]    A primary object of the present invention is to provide a new and improved jack stand for supporting stationary vehicles and other weights which is very rugged in its construction, and simple in its assembly and or construction. 
         [0008]    Another object of the invention is to provide a new and improved stand for supporting vehicles and comparable loads, parts of which are uniform and interchangeable, and, which though particularly rugged, has a structural arrangement permitting it to be relatively light in weight compared to the amount of load it is capable of carrying. 
         [0009]    Still another object of the invention is to provide a new and improved stand for supporting stationary loads which besides being stable in a position for one selected height, can be shifted to accommodate a different selected height without sacrificing its rugged stability. 
         [0010]    Still another object of the supporting is to provide a new and improved stand for supporting stationary loads which is relatively simple and inexpensive not only to manufacture and is build in such a way that it occupies a relatively compact space. 
         [0011]    With these and other objects in view, the invention consists in the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter set forth, pointed out in the appended claims and illustrated in the accompanying drawings. 
         [0012]    To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.

       SUMMARY OF THE INVENTION 
       [0023]    The instant invention provides a jack stand and safety support comprising: four sides that substantially form a pyramid; two of said four sides being opposite each other and including cut outs and handles; a top including a three tier basin that includes an optional drainage channel extending across all tiers and glow in the dark lengthwise strips along the corners of said jack stand and support. 
         [0024]    The present invention also provides a safety support base for a trailer to eliminate the chance of it accidentally falling off the homemade block it sits on, preventing costly damage and possible injury or death. It also provides additional safety features with its bright hunters orange body and built in military style luminescent base and edges, providing an illuminated perimeter around you and your property to warn other drivers of your location at night. 
         [0025]    The support base or stand comes in different sizes to accommodate specific style trailers. The stand is the standard size block which could be used for traditional RVs, Boat, ATV, or pull behind utility trailer. Larger sizes or heavy duty blocks are designed to be used with 5th wheels and works the same way. The small size is a low profile block which could be combined with other sizes and is used as a scissor jack support and illuminated perimeter. The supports or stands of the invention are equipped with military grade glow in the dark strips allowing your trailer to be seen from a distance and allowing you to recognize the location of the hitch during dark hours to prevent you from bumping into it and injuring yourself 
         [0026]    The support or stand of the invention is a pyramid shaped plastic block that is light weight, and comes in a bright hunters orange colors with military grade glow in the dark strips on its edges and base for high visibility. It has built-in inverted handles for easy carrying and positioning. It also has an indented square pocket located on the top to allow the jack stand foot to fit into the “pocket”. The design allows the trailer jack stand to securely sit into the stand or support, preventing it from sliding off the block. The wide base and pyramid design also prevents the block from tipping over in the event of an earthquake, high winds or shifting of the trailer or the ground beneath it. 
         [0027]    The smaller sizes are also pyramid shaped, light weight plastic block in a bright hunter&#39;s orange with military grade glow in the dark strips on its edges and base for high visibility. It also has a deep pocket which allows the scissor jack foot to securely fit into it preventing it from digging into the surface underneath it and helping to provide a safer and more sturdy foundation.
