DETAILED DESCRIPTION OF THE INVENTION

[0028] An embodiment of the present invention is a top toolbox 10 comprised of a cabinet 20 and a frame guide 30 with lifting means to adjust the cabinet 20 from a resting position in which it covers the frame guide 30 to a raised position or raised positions exposing an interior of the frame guide 30. In all the figures except for FIG. 3, the cabinet 20 is in a fully raised position. FIG. 3 shows the top toolbox 10 on a toolbox 40, and the top toolbox 10 is in a resting position with the cabinet 20 lowered over the frame guide 30 (not visible). The toolbox 40 may or may not have wheels 42; however, a toolbox with a lid (not shown) or a toolbox that otherwise prevents the top toolbox from resting on it or being adjustable is not suitable for use with the adjustable top toolbox 10 of the present invention.

[0029] In the embodiment of the present invention shown in FIGS. 2, 3, 5 and 6, the size of the top toolbox 10 corresponds with the toolbox 40 so that the surface area of the workbench 45 on the toolbox 40 is substantially maintained.

[0030] As seen in FIG. 1, the cabinet 20 has a cabinet face 21, floor 22, inner sides 23, outer sides 24, inner back wall 25, outer back wall (not shown), top 27, doors 28 and optional locks 29. FIGS. 2 and 4 show the bottom perimeter 26 of the cabinet 20. It will be understood that the cabinet 20 may have various configurations of shelves, cupboards, doors and/or drawers similarly to a toolbox 40 which may have various configurations of shelves, cupboards, doors and/or drawers.

[0031] As seen in FIGS. 1, 2, 4 and 6, the frame guide 30 has frame guide sides 34 and frame guide back wall 35.

[0032] The top toolbox 10 has lifting means for the cabinet 20 to be raised and lowered electronically, powered by a battery or from an external source. In the embodiment of the invention shown in the figures, the cabinet 20 is raised or lowered through lifting means which provide support underneath top 27 and which raise or lower the top 27 and thereby the cabinet 20 is raised or lowered. As seen in FIGS. 5 and 6, the lifting means is comprised of two telescoping lifting columns 50,51 each having a lower column 50 and upper column 51. In an embodiment of the present invention, the lifting means further comprises supports 57, top bar 59 and a base 58. At the top of each upper column 51 is a support 57, and between supports 57 there is the top bar 59 connecting them.

[0033] The upper columns 51 are activated to rise or lower by pressing a column switch 55 which sends directions to a controller 52 (see FIG. 4) to extend or retract the upper columns 51 in synchrony. When the upper columns extend upwardly, the supports 57 and top bar 59 push up the top 27 of the cabinet 20. While each of the two lifting columns 50,51 are shown alongside each of the frame guide sides 34, it will be understood that other varieties of lifting columns 50 could be used, for example one lifting column in the middle or multiple lifting columns along the back, provided that the cabinet is raised or lowered safely and securely.

[0034] On either side of the top toolbox 10, the frame guide side 34 is sized to fit alongside the inner side wall 23 and between the inner side wall 23 and outer side wall 24 of the cabinet 20. At the back, the frame guide back wall 35 fits between inner back wall 25 and an outer back wall (not shown) of the cabinet 20. Each of the lifting columns 50,51 fit between the frame guide side 34 and the inner side wall 23. The column switch 55 may have buttons (not shown) to press to raise, lower, or stop/pause in lowering or raising the cabinet 20. It will be understood that a remote control or mobile application etc. could be used to activate the controller to cause the lifting columns 50,51 to move the cabinet 20 up and down.

[0035] In a further embodiment of the present invention, the lifting columns 50,51 include an anti-collision feature. With the anti-collision feature, if an object is encountered that provides resistance before the lifting column 50,51 retracts to the resting position at which the cabinet 20 covers the frame guide 30 (and the bottom perimeter 26 reaches the surface of the workbench 45), this triggers the controller to cause the lifting columns 50,51 to raise the cabinet 20 to free the object and stop above it. This anti-collision feature is useful to avoid crushing items, such as a hand, tools or a computer 94 on the workbench 45.

[0036] As shown in FIGS. 4, 5 and 6, in an embodiment of the invention, the cabinet has an undercabinet 60 since the floor 22 is raised rather than being flush with the bottom perimeter 26 of the cabinet 20. In alternative embodiments the floor 22 may be flush with the bottom perimeter 26. This undercabinet 60 allows items to remain on the workbench 45 that fit within the cavity of the undercabinet 60 when the top toolbox 10 is in resting position. FIGS. 1,2, 5 and 6 show how the top 26 is on the supports 57 and top bar 59 which enables the cabinet 20 to be raised and lowered by the extension and retraction of the upper columns 51. It will be understood that in an embodiment of the invention there is no top bar 59 but in the embodiment shown in the figures the top bar 59 adds stability. FIG. 6 shows the outer back wall 31 of the cabinet 20 and the undercabinet 60.

[0037] To support the lifting columns 50,51 there is a base 58, and in this embodiment the base 58 runs along the inner perimeter of the entire frame guide 30 to add additional stability, but in an alternative embodiment the base 58 may only run along the frame guide sides 34. The base 58 may have base holes 62 through which bolts 64 may be inserted to attach the top toolbox 10 to a toolbox 40 (with nuts, not shown, on the end of the bolts 64 within the toolbox 40) to prevent the top toolbox 10 from tipping off of the toolbox 40. In an alternative embodiment the base 58 is positioned only under any lifting columns 50,51 and there may be enough length in the base 58 for base holes 62 adjacent and on either side of the lifting columns 50,51.

[0038] The lifting columns 50,51 may be powered by an external power source, however in the embodiment shown in FIGS. 1 and 4, there is a column battery 56 to provide power for the lifting columns 50,51 to extend and retract. Having an internal battery means that the ability to raise and lower the cabinet 20 is not dependent on an external source of electricity, and thus the toolbox 40 can be moved to where it is needed, even if there is no external power source in that location.

[0039] In an embodiment of the invention shown in FIG. 1, the top toolbox has outer lights 70 turned on by a light switch 72 and powered by lights battery 74. Again, the lights could be powered by an external electrical source, but having the lights battery 74 means that the ability to light up the surrounding area is not dependent on finding an external source of electricity. The outside lights 70 may be used to light the area around the top toolbox 10. In a further embodiment, the top toolbox 10 may have inner cabinet lights 76 (see FIG. 4) to light the inside of the cabinet 20 and/or undercabinet lights 78 to light the workbench 45, which lights may be powered by the lights battery 74.

[0040] As shown in FIG. 2, in an embodiment of the invention there is a power outlet 80 for one or more plugs which may be powered by battery 56 or an external power source (not shown). The power outlet 80 may be used to provide charge for power tools, a computer 94 or cell phone charger etc.

[0041] As shown in FIG. 2, the frame guide back wall 35 and frame guide sides 34 may be used to hang tools 90. Tools may be hung with hooks or on a tool organizing and hanging system (not shown) which is either attached to any of the frame guide back wall 35 and frame guide sides 34. Alternatively, any of the frame guide back wall 35 and frame guide sides 34 may themselves be a tool organizing and hanging system (not shown). While the cabinet 20 is in raised position, larger tools 92 may be hung and a computer 94 may be in open position on the workbench 45. While the top toolbox 10 is in resting position, the size of tools left hanging will be limited by the clearance room between the inner back wall 25 and the frame guide back wall 35 and between the inner side walls 23 and frame guide sides 34, respectively. While the top toolbox 10 is in closed position, the size of items left on the workbench 45 will be limited by the size of any undercabinet 60.

[0042] In the embodiment shown in FIG. 1, the doors 28 have locks 29. To prevent activating the lights and adjust the cabinet position, a master switch for the column switch 55 and light switch 72 could be located within the locked cabinet 20 or the column switch 55 and light switch 72 could be positioned so that when the doors 28 are locked the column switch 55 and light switch 72 can not be accessed and used. It is understood that with different configurations of shelves, cupboards, doors and/or drawers in the cabinet 20, the light switch 72 and column switch 55 may be moved so that they are not accessible when the cabinet is locked up.

[0043] The top toolbox 10 may be sized for any toolbox 40 for which it will used. There are various sizes of toolboxes 40 and the top toolbox 10 may correspond to the size of the toolbox 40 or may be smaller, however it is understood that the top toolbox 10 should rest securely on top of the toolbox 40.

[0044] The frame guide 30 of the top toolbox 10 may additionally comprise a top toolbox workbench (not shown), for example, if a more durable or cut resistant workbench is desired this may be provided by the top toolbox 10. In such an embodiment the top toolbox workbench (not shown) of the top toolbox 10 would rest on top of the workbench 45 of the toolbox 40. Further in an embodiment of the present invention with a top toolbox workbench, the lifting columns 50,51 may be attached to and resting on the top toolbox workbench rather than on the base 58, which would then no longer be necessary.

[0045] The top toolbox 10 may also be constructed without inner sides 23 or without an inner back 25 and in such a case any battery 56, 74 and controller 52 could be located on the floor 22 or inside the top 27 of the cabinet 20.

[0046] While embodiments of the invention have been described in the detailed description, the scope of the claims should not be limited by the preferred embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
