Abstract
A tool box is formed with two counter bores, and includes a handle formed with headed latches. Each of the counter bores has an upper enlarged section and a lower constricted section confined by an inward flange. Each of the headed latches includes an enlarged head received in the enlarged section of the respective counter bore, and a bifurcated shank having a pair of elastic legs that are respectively formed with barbed ends, and extending through the constricted section of the respective counter bore such that the flange is sandwiched between the enlarged head and the barbed ends of the elastic legs.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a tool box, more particularly to a tool box that includes a box body and a handle which can be attached to the box body with ease.




2. Description of the Related Art




Referring to

FIG. 1

, a conventional tool box is shown to include a box body having pivotally connected upper and lower box parts


1


,


2


, and a handle


3


.




The upper box part


1


is formed with a pair of spaced apart handle-mounting seats


101


having opposite end faces formed with mounting holes


102


respectively. The handle


3


includes a generally U-shaped handgrip portion


301


and two insert ends


302


extending into the mounting holes


102


in the handle-mounting seats


101


.




Since a relatively large force is required to slightly bend the handle


3


inwardly so as to permit entry of the handle


3


into a space between the mounting holes


102


, it is relatively inconvenient to insert the insert ends


302


of the handle


30


into the mounting holes


102


in the handle-mounting seats


101


.




SUMMARY OF THE INVENTION




The object of the present invention is to provide a tool box that includes a box body formed with spaced apart handle-mounting seats, and a handle formed with two headed latches that can be easily inserted into counter bores formed in the handle-mounting seats so as to avoid the occurrence of the aforesaid drawback encountered during mounting of the handle to the box body of the conventional tool box.




Accordingly, a tool box of the present invention includes an upper box part, a lower box part, and a handle. The lower box part is pivotally connected to the upper box part, and has a front wall, and two spaced apart handle-mounting seats protruding from the front wall. Each of the handle-mounting seats is formed with a counter bore that has an upper enlarged section, and a lower constricted section reduced from the enlarged section, and has an inward flange confining the constricted section. The handle has two opposite ends, and two headed latches that are respectively formed on the opposite ends of the handle. Each of the headed latches includes an enlarged head, and a bifurcated shank which is reduced from the enlarged head and which includes a pair of elastic legs with barbed ends. The headed latches are fittingly and respectively inserted into the counter bores in the handle-mounting seats in such a manner that the enlarged head of each of the headed latches is received in the enlarged section of a respective one of the counter bores, that the elastic legs extend through the constricted section of the respective one of the counter bores, and that the flange of each of the handle-mounting seats is sandwiched between and abuts against the enlarged head and the barbed ends of the elastic legs of the bifurcated shank of the respective one of the headed latches, thereby preventing removal of the handle from the lower box part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIGS. 2

to


5


, the preferred embodiment of a tool box


10


according to the present invention is shown to include an upper box part


11


, a lower box part


12


, and a handle


30


.




As illustrated, the lower box part


12


is pivotally connected to the upper box part


11


, and has a front wall


40


, and two spaced apart handle-mounting seats


41


protruding from the front wall


40


. Each of the handle-mounting seats


41


is formed with a first counter bore


414


that has an upper enlarged section


413


, and a lower constricted section


412


that is reduced from the enlarged section


413


. Each of the handle-mounting seats


41


has an inward flange


411


confining the constricted section


412


.




The handle


30


is mounted on the lower box part


12


, and includes an elongated handgrip portion


31


having two opposite ends, and two headed latches


32


that are respectively formed on the opposite ends of the handgrip portion


31


. A felt strip


33


is preferably attached to a rear side of the handgrip portion


31


to facilitate gripping of the handgrip portion


31


. Each of the headed latches


32


includes an enlarged head


321


, and a bifurcated shank


322


. The bifurcated shank


322


is reduced from the enlarged head


321


, and includes a pair of elastic legs


3221


with barbed ends


3225


. The headed latches


32


are fittingly and respectively inserted into the first counter bores


414


in the handle-mounting seats


41


in such a manner that the enlarged head


321


of each of the headed latches


32


is received in the enlarged section


413


of a respective one of the first counter bores


414


, that the elastic legs


3221


extend through the constricted section


412


of the respective one of the first counter bores


414


, and that the flange


411


of each of the handle-mounting seats


41


is sandwiched between and abuts against the enlarged head


321


and the barbed ends


3225


of the elastic legs


3221


of the bifurcated shank


322


of the respective one of the headed latches


32


, thereby preventing removal of the handle


30


from the lower box part


12


(see FIG.


6


).




In this embodiment, the elastic legs


3221


of the bifurcated shank


322


of each of the headed latches


32


define a gap


3224


therebetween. The enlarged head


321


of each of the headed latches


32


defines a second counter bore


3211


that is in spatial communication with the gap


3224


and that has an upper enlarged section


3212


and a lower constricted section


3213


reduced from the enlarged section


3212


of the second counter bore


3211


.




The tool box of the present invention further includes a pair of locking bolts


50


. Each of the locking bolts


50


has an enlarged head


51


and a bifurcated cylindrical shank


52


that is reduced from the enlarged head


51


and that is inserted through the second counter bore


3211


in a respective one of the headed latches


32


such that the enlarged head


51


of each of the locking bolts


50


is received in the enlarged section


3212


of the respective one of the second counter bores


3211


. The bifurcated cylindrical shank


52


of each of the locking bolts


50


further extends into the gap


3224


between the elastic legs


3221


of the bifurcated shank


322


of the respective one of the headed latches


32


so as to result in radial and outward expansion of the elastic legs


3221


, which in turn results in tight sandwiching of the flange


411


of the respective handle-mounting seat


41


between the enlarged head


321


and the barbed ends


3225


of the elastic legs


3221


of the respective one of the headed latches


32


, as best shown in

FIG. 7

, thereby enhancing engagement between the headed latches


32


and the handle-mounting seats


41


.




Since the bifurcated shanks


322


of the headed latches


32


can be inserted into the first counter bores


414


in the handle-mounting seats


41


with ease, and since mounting of the locking bolts


50


into the second counter bores


3211


in the enlarged heads


321


of the headed latches


32


can also be conducted in a simple way, the drawback as encountered during assembly of the handle to the box body of the aforesaid conventional tool box can be eliminated.




While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that the present invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
