Tool box assembly

A tool box assembly includes a tool box including two side walls each having a first end portion defining a slot. An inverted U-shaped lid includes two side plates each having a first end portion defining an inverted L-shaped channel and a second end portion pivotally mounted on a second end portion of a corresponding one of the two side walls of the tool box. The channel of each of the two side plates includes a longitudinal recess alignable with the slot and a recess perpendicular to the longitudinal recess. A U-shaped handle includes two legs. Two snapping members each include a stub fixedly mounted on a corresponding one of the two legs of the handle and slidably extending through the longitudinal recess of a corresponding one of the two side plates of the lid and through the slot of an associated side wall of the tool box, and a cone-shaped enlarged head urged on an inner periphery of the side wall of the tool box.

FIELD OF THE INVENTION 
The present invention relates to a tool box assembly. 
BACKGROUND OF THE INVENTION 
A conventional tool box is shown in FIGS. 6 and 7, and a complete 
illustration will follow in the detailed description of the preferred 
embodiments. 
The present invention has arisen to mitigate and/or obviate the 
disadvantage of the conventional tool box. 
SUMMARY OF THE INVENTION 
In accordance with one aspect of the present invention, there is provided a 
tool box assembly comprising a tool box including two elongate side walls 
each having a first end portion defining an elongate slot longitudinally 
disposed and a second end portion. 
An inverted U-shaped lid includes two side plates each juxtaposed to a 
corresponding one of the two side walls of the tool box and each having a 
first end portion defining an inverted L-shaped channel and a second end 
portion pivotally mounted on the second end portion of a corresponding one 
of the two side walls of the tool box. 
The channel of each of the two side plates includes an elongate recess 
longitudinally disposed and alignable with the elongate slot of an 
associated side wall of the tool box, and a short recess perpendicularly 
disposed to the elongate recess. 
A U-shaped handle includes two legs each slidably mounted on the first end 
portion of a corresponding one of the two side walls of the tool box. 
Two snapping members each include a stub fixedly mounted on a corresponding 
one of the two legs of the handle and slidably extending through the 
elongate recess of a corresponding one of the two side plates of the lid 
and through the elongate slot of an associated side wall of the tool box, 
and a cone-shaped enlarged head extending from one end portion of the stub 
and urged on an inner periphery of the side wall of the tool box. 
Further features of the present invention will become apparent from a 
careful reading of the detailed description with appropriate reference to 
the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
For a better understanding of features and benefits of the present 
invention, reference is now made to FIGS. 6 and 7, illustrating a 
conventional tool box in accordance with the prior art. 
The conventional tool box comprises a body 40 pivotally connected with a 
lid 42, each of the body 40 and the lid 42 formed with a projection 44 and 
defining a hole 46. Two pivot members 50 are each pivotally mounted on 
each of the body 40 and the lid 42. Each of the two pivot members 50 
includes a boss 52 received in a respective hole 46 and defines a cavity 
54 for receiving a respective projection 44. 
In operation, each of the two pivot members 50 can be pivoted relative to 
the projection 44 to a position as shown in FIG. 7 such that each of the 
two projections 44 can be received in a respective cavity 54, thereby 
securing the lid 42 on the body 40. 
By such an arrangement, however, the engagement between the projection 44 
and the cavity 54 easily becomes loosened during long-term utilization 
such that the lid 42 tends to be detached from the body 40, thereby 
greatly causing an inconvenience for carrying the tool box. 
Referring now to FIGS. 1-3, a tool box assembly in accordance with the 
present invention comprises a tool box 20 including two elongate side 
walls 21 each having a first end portion defining an elongate slot 22 
longitudinally disposed and a second end portion. 
An inverted U-shaped lid 10 includes two side plates 11 each juxtaposed to 
a corresponding one of the two side walls 21 of the tool box 20 and each 
having a first end portion defining an inverted L-shaped channel and a 
second end portion pivotally mounted on the second end portion of a 
corresponding one of the two side walls 11 of the tool box 20. 
The channel of each of the two side plates 11 includes an elongate recess 
110 longitudinally disposed and alignable with the elongate slot 22 of an 
associated side wall 21 of the tool box 20, and a short recess 112 
perpendicularly disposed to the elongate recess 110. 
The elongate recess 110 of each of the two side plates 11 is formed with a 
plurality of projections 111 extending inwardly. 
A U-shaped handle 30 includes two legs 32 each slidably mounted on the 
first end portion of a corresponding one of the two side walls 21 of the 
tool box 20. 
Two snapping members 33 each include a stub 35 fixedly mounted on a 
corresponding one of the two legs 32 of the handle 30 and slidably 
extending through the elongate recess 110 of a corresponding one of the 
two side plates 11 of the lid 10 and through the elongate slot 22 of an 
associated side wall 21 of the tool box 20, and a cone-shaped enlarged 
head 34 extending from one end portion of the stub 35 and urged on an 
inner periphery of the side wall 21 of the tool box 20 as best shown in 
FIG. 3. The cone-shaped enlarged head 34 of each of the two snapping 
members 33 defines a slit 36 therein. 
The second end portion of each of the two side walls 21 of the tool box 20 
defines a bore 24, and the second end portion of each of the two side 
plates 11 of the lid 10 is formed with an extension 13 defining a hole 131 
aligning with the bore 24 of a corresponding one of the two side walls 21 
of the tool box 20. 
The tool box assembly further comprises two pivot members 60 each including 
a stub 65 extending through the hole 131 of a corresponding one of the two 
side plates 11 of the lid 10 and through the bore 24 of an associated side 
wall 21 of the tool box 20, a cone-shaped enlarged head 64 formed on a 
first end portion of the stub 65 and urged on an inner periphery of the 
side wall 21 of the tool box 20, and an abutting knob 68 formed on a 
second end portion of the stub 65 and urged on an outer periphery of the 
side wall 21 of the tool box 20. The cone-shaped enlarged head 64 of each 
of the two pivot members 60 defines a slit 66 therein. 
In operation, referring to FIGS. 2-5 with reference to FIG. 1, the enlarged 
head 34 of each of the two snapping members 33 can be urged through the 
elongate slot 22 into the side wall 21 of the tool box 20, thereby urging 
on the inner periphery of the side wall 21 of the tool box 20 such that 
the handle 30 can slide along the elongate slot 22. 
Then, the enlarged head 64 of each of the two pivot members 60 can be urged 
through the hole 131 and the bore 24 into the side wall 21 of the tool box 
20, thereby urging on the inner periphery of the side wall 21 of the tool 
box 20 such that the lid 10 is pivotally mounted on the tool box 20 as 
shown in FIG. 2. 
The lid 10 can then be pivoted relative to the tool box 20 to a position as 
shown in phantom lines in FIG. 2 such that the stub 35 of each of the two 
snapping members 33 can be inserted into the short recess 112 to align 
with the elongate recess 110 and the elongate slot 22 as shown in FIG. 3. 
In such a situation, each of the two legs 32 of the handle 30 together with 
the stub 35 of each of the two snapping members 33 can be moved along the 
elongate recess 110 and the elongate slot 22 to a position as shown in 
FIGS. 4 and 5 such that the lid 10 can be secured on the tool box 20. 
It should be clear to those skilled in the art that further embodiments of 
the present invention may be made without departing from the spirit and 
scope of the present invention.
