BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a toolbox for a stepladder and more particularly pertains to holding items at a location on a stepladder for ready access with a toolbox for a stepladder. 
     2. Description of the Prior Art 
     The use of storage devices securable to a ladder is known in the prior art. More specifically, storage devices securable to a ladder heretofore devised and utilized for the purpose of holding items therein for ready access are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     By way of example, U.S. Patent Des. 324,272 to Thiel discloses a ladder tray attachment. U.S. Pat. No. 3,642,240 to Hershey discloses a handyman&#39;s toolbox and ladder accessory. U.S. Pat. No. 4,261,435 to Winter discloses a ladder tray. U.S. Pat. No. 4,913,394 to Schmid discloses a article holding tray assembly for ladder. U.S. Pat. 5,242,031 to Ashley discloses a ladder accessory. 
     While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe a toolbox for a stepladder that allows tools, screws, bolts, and the like to be held and hung at a location on a stepladder for ready access by a user of the stepladder. 
     In this respect, the toolbox for a stepladder according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of holding items therein at a location on a stepladder for ready access. 
     Therefore, it can be appreciated that there exists a continuing need for new and improved toolbox for a stepladder which can be used for holding items therein at a location on a stepladder for ready access. In this regard, the present invention substantially fulfills this need.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular, to FIG. 1 thereof, the preferred embodiment of the new and improved toolbox for a stepladder embodying the principles and concepts of the present invention and generally designated by the reference number 10 will be described. 
     Specifically, the present invention essentially includes two major components. The major components are the container and thumb screws. These components are interrelated to provide the intended function of holding items at a location for ready access on a step ladder. 
     More specifically, it will be noted in the various Figures that the first major component is the container 11. The container is rigid in structure and formed of a clear plastic material. The container has a box-shaped body 12. The body has a rectangular, planar horizontal bottom wall 14 with a periphery therearound. The periphery is formed of a planar vertical front wall 16, a planar vertical rear wall 18, and a pair of opposed planar vertical side walls 20 interconnected between the front wall and rear wall. The periphery is extended upwards to form a storage space directly above the bottom wall and a top opening for allowing access to the storage space. The periphery is also extended downwards to form a holding space 22 directly below the bottom wall and a bottom opening for allowing access to the holding space. The container includes a rectangular planar horizontal lip 24 extended outwards from one side wall near the bottom opening. The lip has plurality of different sized apertures 26 disposed thereon. These apertures are used for hanging tools such as a hammer, screwdriver, drill, or the like therein. The container also includes a first set of spaced vertical rectangular planar dividers 28. The first set of dividers are disposed within the storage space and extended upwards from the bottom wall and laterally between the front and rear walls. The container also includes a second set of vertical rectangular planar dividers 30. The second set of dividers are disposed within the storage space and perpendicularly interconnected between the dividers of the first set. The first set and second set of dividers in combination form a plurality of bins 32 for holding items such as screws, bolts and the like therein. The container also includes a lid 34. The lid is generally box-shaped and rigid in structure. The lid coupled to the body at the rear wall with a pair of rigid hinges 36. The hinges are formed of a rigid material such as metal or plastic. The lid allows access to the storage space in one orientation and prevents access thereto in another orientation. The container also includes a pair of spaced openable latches 38 coupled between the lid and the front wall of the container. The latches are formed of a rigid material such as metal or plastic. The latches are used for securing the lid to the body. The container also includes a threaded first mounting hole 40 disposed on the rear wall near the bottom opening. A threaded second mounting hole 42 is also included and disposed on the side wall opposite the lip at a location near the bottom opening. 
     The second major component of the present invention is the thumb screws 50. The present invention includes a pair of thumb screws. The thumb screws are formed of a rigid material such as metal or plastic. One thumb screw is threadedly disposed within the first mounting hole 40. The other thumb screw is threadedly disposed within the second mounting hole 92. The thumb screws are used for coupling the container to the top step 60 of a step ladder when a top step of a stepladder is positioned within the holding space and the thumb screws are tightened by hand. The container may be removed from the stepladder when the thumb screws are loosened by hand. By securing the top step of the stepladder within the holding space, the stability of the coupling between the present invention and the stepladder is enhanced. Other conventional screws or bolts may also be utilized to perform the coupling function. 
     The present invention is a toolbox which is attached to the platform or top step at the top of a stepladder, thereby permitting items to be readily at hand for use. The present invention is made of a high strength durable plastic which can be clear to permit the contents to be readily available. The size of the present invention could vary with the size of the application or steps of a stepladder. Access within the present invention is provided through a hinged lid. The present invention is fastened to the platform or stepladder by a suitable means such as screws. The present invention provides a lip with apertures thereon for hanging various tools or related items. A plurality of bins are provided within the present invention for allowing organization and storage of items in a convenient, accessible, identifiable, and retrievable manner. A sturdy latching mechanism formed of a pair of spaced latches holds the lid closed even when the stepladder is folded and carried on its side. 
     The present invention is used to hold implements and items which are associated with work to be performed by a user. Properly prepared, the present invention eliminates endless climbing up and down of the stepladder by a user to obtain tools, fasteners, and the like. Even tools such as electric drills can be placed upon or hung from the present invention for use. The present invention intended to be utilized by people who hang draperies and shades. It is also readily adapted for use by electricians, contractors, builders, and homeowners. 
     As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modification and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modification and equivalents may be resorted to, falling within the scope of the invention.
