Description

l. Field of the Invention The invention relates to a toolbox structure comprising a first case,a second case pivotally connecting to the first case, and a number ofboxes; wherein a plurality of projecting pillar sets, each including twopairs of projecting pillars opposite to each other, are disposed at leastinside the first case to engage with a stepped recess fonned on thebottom of each box for allowing each box to be fixed and limited inposition well. Accordingly, not only can problems of messy placementand casual movement of the boxes inside the toolbox be solved, but usersenable to carry those boxes fully or in part according to their demands for much more convenience and flexibility in use thereof. 2. Description of Related Art Toolboxes are mainly utilized for accommodating a variety oftools and parts, e.g. wrenches, screwdrivers, nuts, nails and the like. Ingeneral, traditional toolboxes have two corresponding cases for bucklingup each other. Many containers, tiered drawers, or compartments are disposed or separated by a plurality of bulkheads inside cases.

Although the toolbox structures described above can be used toclassify parts, they have many disadvantages, i.e. parts are easy to fallout from storage containers or compartments due to a lack of fitness forbulkheads and cases of a toolbox. Therefore, users may have difficulties in finding out appropriate parts Which are scattered inside the toolbox.

However, When using a traditional toolbox, users cannot carrymerely the parts they Want; instead, they need hold the traditionaltoolbox With all the parts therein every time, Which causes great burdensfor users. Thereby, how to accommodate all kinds of parts Well Withoutthe disadvantages, i.e. messy scattered in the toolbox, becomes an important object on improving traditional toolboxes.

For instance, an international patent WO 2011/078763 A1, issuedon 30th Jun. 2011, disclosed a module system comprises a case and anumber of boxes. Each box is defined by a cross-sectional area of anopening of the respective box, the case has a case lid and a case bottompart, Where the case lid and the case bottom part fonns an interior spaceWithin the case, and the boxes are to be stored in the interior space of thecase, characterized in that the cross-sectional area of one box isapproximately a multiple of any cross-sectional area of any of thenumber of boxes that are to be stored in the interior space of the case, and the case lid is provided With sealing means that appropriately fits over and in abutment With an upper surface of at least one box, With thecase in closed position, When the boxes are stored in the interior space ofthe case. In this patent, although there are many sealing means disposedinside the case lid for sealing the upper surfaces of boxes to fix boxesfirmly, the module system still have a problem, i.e. the sealing means areprone to have abrasion resulting in the boxes loosing from the case, after being used for a long time.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the object of thepresent invention is to provide a toolbox structure having pluralprojecting pillars sets inside a case thereof for limiting and fixing plural boxes in position therein.

Disclosed herein is a toolbox structure including a first case, asecond case pivotally connecting to the first case and a number of boxes,Wherein plural projecting pillar sets, each including two pairs ofprojecting pillars opposite to each other, are disposed at least inside thefirst case. The first case is provided With at least one buckle, and thesecond case is provided With at least one hooking part for correspondinginterconnection With the buckle of the first case. In the foregoing description, the projecting pillars opposite to each other are connected by a connecting part having a height same With that of the proj ecting pillar.Each box is equipped With a stepped recess at the bottom thereof to engage With the projecting pillar for fixing and positioning purposes.

According to an embodiment of the present invention, the firstcase is provided With a handle so that the user can lift the toolbox easily.Moreover, the first case can provided With at least one pivot, and thesecond case provided With at least one groove for receiving the pivot so that the first and the second cases of the toolbox can be tightly closed.

According to an embodiment of the present invention, each boxmay be equipped With four lateral Walls sloping towards the bottom ofthe box. Furthennore, the box is provided With a lid having a recessedbinding border for tightly binding to a top edge of the box. The top edgeof the box is further provided With an ambient rim extemally extendedtherefrom, and a protruding block in various shapes is fiirther disposedon the ambient rim for users to easily open the lid. The net surface areaof the lid obtained from subtracting the area of the binding border fromthat of the lid top is equal to the bottom area of the box so that users canplace and stack the same size box they took out on the lid of the other boxes.

Accordingly, the plural boxes inside the cases can steadily stay onthe projecting pillars in all possible conditions, e.g. transportation or thelike, so that messy placement or arbitrary displacement of boxes can beavoided. Moreover, users can choose to carry the boxes in part or fiillybased on their demands so that it is more convenient for users to carry a toolbox with a lighter weight.
