Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to power hand tools and more
specifically, to a toolbox for holding a power hand tool and its
accessories.
[0003] 2. Description of the Related Art
[0004] Regular electricity-powered hand tools include two types,
namely, the battery-operated hand tools (mobile power hand tools)
and the city power-operated hand tools. Following the development
of Do-It-Yourself industry, battery-operated hand tools are widely
accepted by consumers.
[0005] An electricity-powered hand tool may be used with different
tool accessories, such as different sizes of adapters and different
sizes of screwdriver and/or drill bits. It is necessary to use a
box to carry these tool accessories. Therefore, a consumer needs to
buy different tool accessories and a toolbox when purchasing an
electricity-powered hand tool.
[0006] Further, when the battery power of a battery-operated hand
tool is low, the user must use a specific battery charger to charge
the battery of the hand tool. Therefore, when buying a
battery-operated hand tool, the consumer shall also have to buy a
battery charger.
[0007] It is expensive to prepare a power hand tool, a battery
charger and a set of tool accessories respectively. Further, it is
inconvenient to carry the prepared power hand tool with the related
battery charger and tool accessories.
SUMMARY OF THE INVENTION
[0008] The present invention has been accomplished under the
circumstances in view. It is therefore one object of the present
invention to provide a toolbox, which accommodates a power hand
tool as well as the related tool accessories.
[0009] It is another object of the present invention to provide a
toolbox, which accommodates a battery-operated hand tool and the
related tool accessories and can simultaneously charge the battery
of the storage battery-operated hand tool.
[0010] To achieve these objects of the present invention, the
toolbox comprises a housing and a holder base. The housing has a
top retaining recess for the positioning of a power hand tool, and
a receiving space. The holder base is detachably coupled to the
housing for holding accessories to be used with the power hand tool
positionable in the top retaining recess in the receiving space of
the housing. A battery charger can be provided and mounted in the
housing. The battery charger has two conductive terminals located
at the top retaining recess of the housing for charging the power
hand tool that is positioned in the top retaining recess.

DETAILED DESCRIPTION OF THE INVENTION
[0015] As shown in FIGS. 1 and 2, a toolbox 100 in accordance with
the first preferred embodiment of the present invention comprises a
housing 10, a battery charger 20, and a holder base 30.
[0016] The housing 10 comprises a top cover shell 11 and a bottom
shell 12. The top cover shell 11 has a top retaining recess 111
adapted to positively accommodate a power hand tool such as a
battery-operated hand tool, a plurality of receiving grooves 114
respectively formed in the two opposite lateral sidewalls, an
inside chamber 115, two through holes 112 formed in the top wall
and disposed in communication between the top retaining recess 111
and the inside chamber 115, a bottom opening 116 in communication
with the inside chamber 115 and the outside space, a bottom
coupling groove 117 extending around the bottom opening 116, and a
hook hole 113 formed in the inside wall at one end near the bottom
opening 116. The top retaining recess 111 has a profile fitting the
profile of the power hand tool to be positioned therein.
[0017] The bottom shell 12 has a peripheral coupling flange 124 for
fastening to the bottom coupling groove 117 of the top cover shell
11, a hook 121 disposed at one end for hooking in the hook hole 113
of the top cover shell 11, two coupling holes 122 disposed near the
two distal ends, two rows of vertically extending recessed bottom
grooves 125 and a rectangular bottom receiving chamber 126. The
bottom grooves 125 and the bottom receiving chamber 126 are
respectively formed by recesses that are respectively upwardly
recessed from a bottom of the bottom shell 12, such that the bottom
grooves 125 and the bottom receiving chamber 126 define a receiving
space at the bottom side of the bottom shell 12 and a plurality of
top protrusions 123 at the top side of the bottom shell 12.
[0018] The top cover shell 11 is fastened to and covered on the
bottom shell 12 to force the hook 121 and the peripheral coupling
flange 124 of the bottom shell 12 into engagement with the hook
hole 113 and bottom coupling groove 117 of the top cover shell 11.
At this time, the bottom shell 12 blocks the bottom opening 116 of
the top cover shell 11, and the top protrusions 123 of the bottoms
hell 12 are received in the inside chamber 115 of the top cover
shell 11.
[0019] The battery charger 20 is adapted to charge the battery of a
battery-operated hand tool that is positioned in the top retaining
recess 111 of the top cover shell 11. The battery charger 20
comprises a charging circuit board 22 and two parallel conductive
terminals 21 respectively electrically connected to the circuit
board 22. The battery charger 20 is fixedly mounted on the top side
of the bottom shell 12. When the top cover shell 11 and the bottoms
hell 12 are fastened together, the battery charger 20 is received
in the inside chamber 115 of the top cover shell 11, and the two
conductive terminals 21 of the battery charger 20 extend through
the through holes 112 of the top cover shell 11 and are exposed in
the top retaining recess 111.
[0020] The holder base 30 comprises a spring hook 31 and a coupling
tongue 33 disposed at the two distal ends corresponding to the
coupling holes 122 of the bottoms hell 12, and a plurality of top
receiving holes 32 and receiving portions 34 for holding different
tool accessories such as adapters 35 and bits 36. The spring hook
31 and the coupling tongue 33 are respectively forced into
engagement with the coupling holes 122 of the bottoms hell 12 to
secure the holder base 30 to the bottom side of the bottoms hell
12, keeping the storage adapters 35 and bits 36 be received in the
rectangular bottom chamber 126 and the recessed bottom grooves 125
of the bottom shell 12.
[0021] Referring to FIG. 3, the toolbox 100 can carry a
battery-operated hand tool A in the top retaining recess 111 of the
top cover shell 11 of the housing 10. After insertion of the
battery-operated hand tool A into the top retaining recess 111 of
the top cover shell 11 of the housing 10, the charging terminals of
the battery (not shown) of the battery-operated hand tool A are
kept electrically connected to the conductive terminals 21 of the
battery charger 20, and therefore the battery of the
battery-operated hand tool A is charged by the battery charger 20.
Further, the toolbox 100 can also receive different adapters 35 and
bits 36. When wishing to use the adapters 35 and/or the bits 36,
the user can easily detach the holder base 30 from the bottom shell
12 of the housing 10 by disengaging the spring hook 31 from the
respective coupling hole 122.
[0022] FIG. 4 shows a toolbox 200 constructed according to a second
preferred embodiment of the present invention. According to this
embodiment, the toolbox 200 is comprised of a housing 40, a battery
charger (not shown), and a holder base 50. The structure of the
toolbox 200 is substantially similar to the aforesaid first
preferred embodiment with the exception of the following
features.
[0023] The holder base 50 has one end pivotally coupled to the
housing 40. Therefore, the holder base 50 can be turned in and out
of the receiving space 41 of the housing 40. Further, the holder
base 50 has a hook 51 disposed at the free end for hooking in an
inside wall of the housing to hold the holder base 50 in the close
position.
[0024] Although a particular embodiment of the invention has been
described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the invention. Accordingly, the invention
is not to be limited except as by the appended claims.
