DETAILED DESCRIPTION OF THE INVENTION

[0025] The above described drawing figures illustrate the invention in at least one of its preferred embodiments, which is further defined in detail in the following description.

[0026] The present invention is a portable toolbox apparatus with several other key functions which will be described below. A top 10, bottom 20, front 30 and rear 40 panels form a box structure 50 with opposing sides 60, 70 tilted off-vertical to mutual converge upwardly. A plurality of hinged drawers 80 and fixed bins 90 are arranged on each of the opposing sides 60, 70. These drawers 80 and bins 90, being accessible from the outside of the apparatus function as a parts and tool crib to make the availability of items needed in working more convenient. The tilt of the sides provides for maintaining closure of the draws 80 and movement of items to the rear of the drawers and bins to prevent loss. The rear panel 40 terminates downwardly at a pair of supporting feet 100 which are positioned for resting the apparatus in contact with a supporting surface 110. The top panel 10 provides an upwardly facing work surface 12 defining a pair of hand holes 14 separated by a hand grip 16 for carrying the portable toolbox. This surface 12, may be used to sit upon when working, to stand upon for reaching and for placing a workpiece (not shown) upon when working. A forward 120 and a rearward 130 sliding retractable work surface extender frames, are each linearly positionable between a retracted position “R1” secured within the box structure 50, as shown in FIGS. 2 and 5, and an extended position “E1” directed and positioned outwardly from the box structure 50, as shown in FIGS. 1 and 6, where partial and full extension is depicted.

[0027] Preferably, a pair of spaced apart rotating wheels 140 are mounted, as shown in FIG. 1, adjacent to the supporting feet 100, the wheels positioned above the supporting surface 110 when the work surface 12 is horizontal, as shown in FIG. 5 where the apparatus rests on the supporting feet 100 at the rear of the apparatus, and on the front panel 30 at the front of the apparatus. However, the wheels 140 contact the supporting surface 110 for supporting the apparatus in rolling motion, when the forward extender frame 120 is lifted as a handle for pulling the apparatus, and this is shown in FIG. 4 where the wheels 140 rather than the feet 100 contact the supporting surface 110.

[0028] A forward 150 and a rearward 160 extender frame braces engage the box structure 50 and are enabled for linear positioning between a retracted position “R2” fully secured within the box structure 50, as shown in FIG. 2, and an extended position “E2” directed outwardly from the box structure 50, as shown in FIG. 1 (partially extended) and FIG. 6 (fully extended). the extender frame braces 150, 160 are each enabled for upward pivoting and engaging of a terminal end 155 of one of the extender frames for providing rigidizing support as the extender frames 120, 130 are designed to receive loads in supporting work pieces.

[0029] Each one of the hinged drawers 80 comprises an open top pocket structure 82 providing an interior drawer volume 84. Each hinged drawer 80 is movable between a closed attitude “C” wherein the interior drawer volume 84 is inaccessible and an open, laterally outwardly tilted, attitude “O” providing access to the interior drawer volume 84 for placement and removal of tools and hardware. Preferably, each one of the fixed bins 90 provides a bottom bin surface 92 angled for urging hardware toward a rear wall 94 of the fixed bin 90.

[0030] The front panel 30 comprises a left 12 and a right 14 front panel portions, where the front panel portions are spaced apart (FIG. 2) providing access to an interior box volume 55. At least one sliding shelf 170 is mounted on side strips within the volume 55, for enabling movement thereof between a retracted shelf position fully enclosed within the interior box volume 55, and an extended shelf position partially extending forward of the front panel 30 for providing access to tools and parts placed on it. Further, an interior drawer 180 may be similarly mounted for sliding access as further shown in FIG. 2. An interior bottom surface 190 is provided for storing heavy items and raw materials.

[0031] While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. Rather, the scope of the invention is to be interpreted only in conjunction with the appended claims.
