Description




FIELD OF THE INVENTION




The present invention relates to a tool box which is assembled by a first part which is composed of two boards folded in a form of an L-shaped part, and a second part part which is composed of three boards folded in a form of a U-shaped part. The two parts are assembled to be a box with an open side into which drawers are slidably received.




BACKGROUND OF THE INVENTION




A conventional tool box is generally includes a box-like body and a cover which is pivotally connected to the box. The box-like body and the cover are manufactured by way of blowing which employs blowing machine to blow air into plastic material in a mold so as to form the hollowed board. The blowing process is properly suitable for manufacturing tool boxes having simple structure as described above. However, tool boxes nowadays are required to include multiple layers so as to receive more tools or bits. The multiple-layer tool box needs more molds and the molds have complicated figures, this usually costs a lot.




The present invention intends to provide a tool box which is assembled by two foldable parts and each part includes two or three boards. The boards are connected with each other by engaging projections in one board with recesses in another board.




SUMMARY OF THE INVENTION




In accordance with one aspect of the present invention, there is provided a tool box and comprising a first part having a first board and a second board which is pivotally connected to the first board. The first part is in a form of an L-shaped part. The second part comprises a middle board with a third board and a fourth board respectively connected to tow sides of the middle board. The second part is in a form of an L-shaped part. The first part is engaged with the second part to form a box with a front opening. A plurality of drawers are slidably received in the tool box via the front opening and are moved along rails on the insides of the third board and the fourth board.




The primary object of the present invention is to provide a tool box that is composed of an L-shaped first part and a U-shaped second part. Each of the first part and the second part is made by way of blowing by a simple mold so that the cost for manufacturing the tool box is low.




These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.

13


, and a first inclined surface


120


is defined in a side of the first board


12


and a second inclined surface


130

130


. A plurality of first projections


131


extend from the second inclined surface


130


and a plurality of first recesses


121


are defined in the first inclined surface


120


so that the first projections


130


are engaged with the first recesses


121


when the first inclined surface


120


matches with the second inclined surface


130


. Therefore, the first part


10


is an L-shaped part. A plurality of second projections


122


extend from two sides of the first board


12

120


connected between the two sides having the second projections


122


. A plurality of second recesses


132


are defined in the other three sides of the second board


13


.




The second part


20


has a middle board


23


with a third board


22


and a fourth board


24


respectively connected to two sides of the middle board


23


. A first side of the middle board


23


is a third inclined surface and a plurality of third recesses


222


are defined in the third inclined surface of the middle board


23


. A second side of the middle board


23


is a fourth inclined surface and a plurality of fourth recesses


2220


are defined in the fourth inclined surface of the middle board


23


. The third board


22


has a fifth inclined surface


25


which is connected to the first side of the middle board


23


. A plurality of third projections


220


extend from the fifth inclined surface


25


. The fifth inclined surface


25


is matched with the third inclined surface of the middle board


23


and the third projections


220


are engaged with the third recesses


222


. A plurality of rails


225


extend from an inside of the third board


22


.




The fourth board


24


has a sixth inclined surface


26


which is connected to the second side of the middle board


23


. A plurality of fourth projections


242


extend from the sixth inclined surface


26


. The sixth inclined surface


26


is matched with the fourth inclined surface of the middle board


23


and the fourth projections


242


are engaged with the fourth recesses


2220
