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.
