Description
FIELD OF THE INVENTION
[0001] The present invention relates to a protection strip, and
more particularly, to a protection strip for a tool box made by way
of blowing molding.
BACKGROUND OF THE INVENTION
[0002] A conventional tool box made by way of blowing molding is to
pour thermoplastic material into molds and pressurized air is
introduced into the mold to expand the thermoplastic material to
contact against the inside of the molds. After the thermoplastic
material is cooled, the molds are separated from the cooled
thermoplastic material so as to form the tool box.
[0003] However, there are some drawbacks for the tool box made by
way of blowing molding, the main concern is that the structural
strength of the tool box is weak. The tool box is designed to
receive metal tools such as screwdrivers, sockets, wrenches,
pliers, hammers, nails or the like, which are heavy and some have
sharp tips. If the tool box falls from a height and hits on the
ground or an object, the corners of the tool box can easily be
broken. Once there is a broken hole or even a crack, the tool box
tends to be torn apart.
[0004] The present invention intends to provide a protection strip
for a tool box and the protection strip protects the weakest area
of the tool box.
SUMMARY OF THE INVENTION
[0005] The present invention relates to a tool box which comprises
a case having a recessed area defined in an outside thereof, and
the recessed area comprises a first recessed corner, a second
recessed corner and a connection recess portion which is connected
between the first and second recessed corners. A stop is formed on
at least one side of the connection recessed portion. Two grooves
are defined in the outside of the case.
[0006] A protection strip comprises a first corner, a second corner
and a connection portion which is connected between the first and
second corners. Each of the first and second corners has a hook
formed thereto which extends toward a top of the first/second
corner. The protection strip is securely engaged with the recessed
area wherein the hooks are engaged with the grooves of the case and
the connection portion of the protection strip is engaged with the
stop of the case.
[0007] The primary object of the present invention is to provide a
protection strip which is securely engaged with the recessed
portion defined at the corner of the tool box so as to reinforce
the structural strength of the tool box.
[0008] 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, a preferred embodiment in accordance with the present
invention.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] FIG. 1 is an exploded view to show two protection strips of
the present invention and the tool box;
[0010] FIG. 2 is a top view to show that the two protection strips
of the present invention are connected to the tool box;
[0011] FIG. 3 is an end cross sectional view of the two protection
strips of the present invention connected to the tool box;
[0012] FIG. 4 is an enlarged cross sectional view to show the
engagement of the hooks of the protection strip and the grooves of
the tool box;
[0013] FIG. 5 is a front side cross sectional view of the two
protection strips of the present invention connected to the tool
box, and
[0014] FIG. 6 is an enlarged cross sectional view to show the
engagement of the connection portion of the protection strip and
the stop of the tool box.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] Referring to FIGS. 1 to 4, the tool box made by way of
blowing molding includes two cases 1 which are the base part and
the cover of the tool box. Each of the cases 1 has a recessed area
10 defined in an outside thereof, and the recessed area 10
comprises a first recessed corner 101, a second recessed corner 102
and a connection recess portion 103 which is connected between the
first and second recessed corners 101, 102. The connection recessed
portion 103 of the case 1 communicates with the first and second
recessed corners 101, 102. At least one of the free ends of each of
the grooves 105, 106 directly or indirectly communicates with a top
surface or a bottom surface of the first and second recessed
corners 101, 102. A stop 104 is formed on at least one side of the
connection recessed portion 103. Two grooves 105, 106 are defined
in the outside of the case 1.
[0016] Two protection strips 2 are securely engaged with the two
respective recessed portions 10 of the two cases 1 and each
protection strip 2 comprises a first corner 21, a second corner 22
and a connection portion 23 which is connected between the first
and second corners 21, 22. Each of the first and second corners 21,
22 has a hook 25/26 formed thereto which extends toward a top of
the first/second corner 21/22.
[0017] It is noted that the first and second corners 21, 22 of the
protection strip 2 can be two individual parts and are individually
connected to two different positions of the connection portion 23.
The first and second corners 21, 22 of the protection strip 2 can
also be integrally connected to two different positions of the
connection portion 23. Alternatively, either one of the first and
second corners 21, 22 of the protection strip 2 can be fixedly or
movably connected to two different positions of the connection
portion 23. The first and second corners 21, 22 of the protection
strip 2 are rounded corners and matched with the first and second
recessed corners 101, 102 of the case 1.
[0018] When connecting the protection strip 2 to the recessed area
10 of the case 1, the connection portion 23 of the protection strip
2 is engaged with the connection recessed portion 103 of the
recessed area 10, and the hook 25 of the first corner 21 and the
hook 26 of the second corner 22 of the protection strip 2 are
respectively located corresponding to the first and second recessed
corners 101, 102 of the case 1. Due to the flexibility of the
material of the protection strip 2, the user pulls the first hook
25 and engages the first hook 25 with the groove 105. Therefore,
the first corner 21 is securely mounted to the first recessed
corner 101. Then, the user pulls the second hook 26 and engages the
second hook 26 with the groove 106. Therefore, the second corner 22
is securely mounted to the second recessed corner 102. The
connection portion 23 is stopped against the stop 104. The
protection strip 2 is then securely engaged with the recessed area
10 of the case 1. Therefore, the corners of the case 1 are well
protected by the protection strip 2.
[0019] It is noted that the protection strip 2 can be composed of
three individual parts which are the first corner 21, the second
corner 22 and the connection portion 23, the three parts are
connected to each other by any known method.
[0020] The protection strip 2 can absorb impact force to protect
the corners of the case 1 from being damaged.
[0021] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
