Supplementary accessory case for tool chest
Abstract
A supplementary accessory case for tool chest mainly includes
two separated boxes and two parallel connecting members separately
extended between two longitudinal sides of the two boxes with an
opening defined among them. Each of the two boxes is provided at a
transverse outer edge with a projected ear, to which a curved catch
hook is rotatably connected. When the supplementary accessory case
is positioned on a top of the tool chest, the opening defined by
the boxes and the connecting members allows a handle of the tool
chest to expose therefrom for holding, and the catch hooks can be
turned downward about the projected ears to engage with retaining
blocks correspondingly provided on the tool chest and thereby
detachably lock the supplementary accessory case to the top of the
tool chest. Extra tools and accessories may be directly accessed
without the need of opening the tool chest.

at an inner edge thereof and a shaft connected to and extended
between said two lugs, said shaft including two arms
perpendicularly extended from two ends of said shaft to hold a
crossbar therebetween, and said crossbar being adapted to tightly
but rotatably fit in said retaining groove on said projected ear
provided on said transverse outer edge of each said box; whereby
when said supplementary accessory case is positioned on the top of
said tool chest, said opening defined by said boxes and said
connecting members allows said handle of said tool chest to expose
therefrom for holding, and said catch hooks can be turned downward
about said crossbars fitted in said retaining grooves of said ears
to engage with said projected retaining blocks on said tool chest,
and thereby detachably lock said supplementary accessory case to
the top of said tool chest for holding extra tools and accessories
or parts.
Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a supplementary accessory
case for tool chest, and more particularly to an accessory case
that may be detachably attached to a top of a tool chest for
conveniently holding small tools and accessories to increase the
value of the tool chest.
[0002] A tool chest is an important and necessary item for general
servicemen or maintenance men and workers to perform their work
efficiently. Various kinds of tools and accessories are held in
separated compartments fixedly formed in the tool chest. It is very
possible some extra small tools and accessories are needed to
perform some works and there is not sufficient space in the tool
chest to hold them. Therefore, these extra tools and accessories
frequently confuse the workers.
SUMMARY OF THE INVENTION
[0003] A primary object of the present invention is to provide a
supplementary accessory case for detachably attached to a top of a
tool chest, so that extra small tools and accessories could be
conveniently held in the supplementary accessory case and accessed
without the need of opening the tool chest.
[0004] To achieve the above and other objects, the supplementary
accessory case of the present invention mainly includes two
separated boxes and two parallel connecting members separately
extended between two longitudinal outer sides of the two boxes with
an opening defined among them. Each of the two boxes is provided at
a transverse outer edge with a projected ear, to which a curved
catch hook is rotatably connected. When the supplementary accessory
case is positioned on a top of the tool chest, the opening defined
by the boxes and the connecting members allows a handle of the tool
chest to expose therefrom for holding, and the catch hooks can be
turned downward about the projected ears to engage with retaining
blocks correspondingly provided on the tool chest and thereby
detachably lock the supplementary accessory case to the top of the
tool chest.
[0005] The curved catch hook includes two symmetrical lugs spaced
at an inner edge thereof. The lugs are provided with centered
through holes, with which two ends of a fixing pin extended through
a hollow shaft are engaged. The hollow shaft includes two arms
perpendicularly extended from two-ends of the shaft, and a crossbar
connected to and extended between free ends of the two arms. The
crossbar is adapted to tightly but rotatably fit in a retaining
groove on the projected ear provided on the transverse outer edge
of each box, so that the catch hook is connected to the ear by
engaging the crossbar with the retaining groove, and may be swung
about the crossbar relative to the projected ear.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] The structure and the technical means adopted by the present
invention to achieve the above and other objects can be best
understood by referring to the following detailed description of
the preferred embodiments and the accompanying drawings,
wherein
[0007] FIG. 1 is a perspective view of a supplementary accessory
case for tool chest according to the present invention;
[0008] FIG. 2 is an exploded perspective view of a catch hook for
connecting the supplementary accessory case of the present
invention to a tool chest;
[0009] FIG. 3 shows the connection of the supplementary accessory
case of the present invention to the tool chest; and
[0010] FIG. 4 is an assembled side view showing the supplementary
accessory case of the present invention has been connected to the
tool chest.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] Please refer to FIG. 1 that is a perspective view of a
supplementary accessory case 100 according to the present
invention. As shown, the supplementary accessory case 100 mainly
includes two separated boxes 1 located at two outer ends thereof,
and two parallel connecting members 2 separately extended between
two longitudinal sides of the two boxes 1, so as to connect the two
boxes 1 to each other to provide an integral supplementary
accessory case 100. Each of the boxes 1 is provided at a transverse
outer end with a projected ear 11 (see FIG. 2), on which a
retaining groove 111 is provided for a catch hook 3 to rotatably
connect thereto.
[0012] FIG. 2 is an exploded perspective view of the catch hook 3.
As shown, the catch hook 3 includes a curved body having two
symmetrical lugs 31 spaced at an inner edge thereof. The lugs 31
are provided with centered through holes 311, with which two ends
of a fixing pin 33 extended through a hollow shaft 32 are engaged.
The hollow shaft 32 includes two arms 34 perpendicularly extended
from two ends of the shaft 32, and a crossbar 35 connected to and
extended between free ends of the two arms 34. The crossbar 35 is
adapted to tightly but rotatably fit in the retaining groove 111 on
the projected ear 11 provided on the transverse outer edge of each
box 1, so that the catch hook 3 is connected to the ear 11 by
engaging the crossbar 35 with the retaining groove 111, and maybe
swung about the crossbar 35 relative to the projected ear 11.
[0013] Please refer to FIGS. 3 and 4. The supplementary accessory
case 100 is designed for positioning on a top of a tool chest 4.
For this purpose, the tool chest 4 is provided at two upper
transverse edges with two retaining blocks 41 for engaging with the
catch hooks 3 when the latter are turned downward. By pushing the
downward turned catch hooks 3 inward, the catch hooks 3 are adapted
to tightly engage with the retaining blocks 41 to lock the
supplementary accessory case 100 to the top of the tool chest 4.
Small-size tools and/or accessories and parts may be directly
positioned in the supplementary accessory case 100 instead of an
additional tool chest 4.
[0014] Since the supplementary accessory case 100 includes two
separated boxes 1 connected to each other via the connecting
members 2, an opening is defined among the two boxes 1 and the two
connecting members 2 to allow a handle 42 on the top of the tool
chest 4 to expose from the opening when the supplementary accessory
case 100 is locked to the top of the tool chest 4. That is, the
tool chest 4 may still be conveniently carried at the handle 42
even the supplementary accessory case 100 is locked to the top
thereof. The supplementary accessory case 100 may be moved along
with the tool chest 4 to hold extra tools and accessories and
parts. The supplementary accessory case 100 not only enables the
tool chest 4 to have an increased capacity, but also enables
convenient access of the extra tools and accessories and parts
without the need of opening the tool chest 4, allowing user to work
in more efficient manner.
