Tool cabinet fixing and supporting structure
Abstract
The present invention discloses a tool cabinet fixing and
supporting structure, which comprises at least one shelf, four
corner bars disposed at the four corners of the shelf, and a
positioning member disposed between the shelf and the corner bars;
wherein the positioning member has a connecting surface being
coupled to an installing surface of the corner bar and having a
limit bolt for supporting a positioning hole disposed on a bottom
plate of the shelf. Such an arrangement constitutes the fixing and
supporting relation between the corner bars and the shelf. Further,
positioning holes are disposed on the installing surface of the
corner bar and a transversal board for passing the fastening member
through the positioning holes to securely mount the shelf onto the
corner bars, and thus constituting an easy-to install tool cabinet
with a better supporting strength.

Description
FIELD OF THE INVENTION
[0001] The present invention relates to a tool cabinet fixing and
supporting structure, and more particularly to a tool cabinet
providing several layers of open shelves for storing various
tools.
BACKGROUND OF THE INVENTION
[0002] Please refer to FIG. 1 for the P.R.C. Patent Publication No.
CN2386927Y, which discloses a traditional tool cabinet assembly
structure. Since traditional tool cabinet simply passes a
positioning member through a circular positioning hole disposed
between a shelf and a corner bar to fix the tool cabinet, the
corner bars at the four corners and the shelves cannot be fixed
effectively, and it is difficult to assemble the tool cabinet. The
patent specification of the aforementioned patent disclosed a tool
cabinet assembly structure comprising a pair of shelves and two
pairs of vertical components (corner bars). Each shelf further
comprises two pairs of horizontal components; wherein each of the
horizontal and vertical components has a plurality of rectangular
openings, circular openings, bolts, and connecting sections of the
rectangular openings; and a screw positioning member having a
corner bar limit section disposed at the connecting position of a
bolt and a nut for combining each shelf with each vertical
component and forming a tool cabinet with stronger assembly
structure. However, the assembly structure of such patent still has
the following shortcomings to overcome:
[0003] 1. The vertical component (corner bar) must support the
total weight of the shelves and the tools placed on the shelves.
Therefore, the rigidity of the corner bar becomes a key issue;
however, there are openings on the vertical component according to
that patented technology. The weight actually borne by the vertical
component is an issue if the number of required shelves increases.
Furthermore, the openings also ruin the overall artistic appearance
and the rough edges of the openings if not trimmed may cut users
easily.
[0004] 2. Since the bolt is formed by bending inwards, it bears a
lighter weight. In addition, there is a tolerance for the bending
angle of each bolt, so that when the shelf is put onto the bolts of
the vertical component, the vertical component and the horizontal
component of each shelf are not fully attached, and thus it is
unable to secure the screws. As for traditional tool cabinets, such
a technology only provides a partial improvement, but does not
achieve the effect of mounting the shelves securely into a fixed
position on the tool cabinet.
[0005] 3. There is another shortcoming related to the design of the
bolt and the transportation and storage of the tool cabinet. Since
the bolt is protruded to create a gap between the vertical
component and the bolt, therefore the vertical components cannot be
stacked on each other. Such an arrangement increases transportation
costs and storage space.
SUMMARY OF THE INVENTION
[0006] The primary objective of the present invention is to
overcome the foregoing shortcomings and avoid the existing
deficiencies by providing a tool cabinet that makes use of a
positioning member disposed between the shelf and the corner bars
to fix the positioning member with its installing surface to the
inner wall of the corner bars without changing the structure of the
current existing corner bars. A limit bolt is extended from the
positioning member to receive a positioning hole disposed at the
bottom of the shelf to constitute a positioning and supporting
relation with the corner bars. Since the supporting surface is
located at the bottom surface of the shelf, therefore the shelf and
the connecting surface of the corner bars can be attached better to
position more effectively. Further, a positioning hole is disposed
on the installing surface of the corner bar and the transversal
board, and a positioning member is used to pass through the
positioning hole to constitute a coupling relation between the
shelf and the corner bars, and thus forming an easy-to install tool
cabinet with better supporting strength.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] To make it easier for our examiner to understand the
objective of the invention, its structure, innovative features, and
performance, we use a preferred embodiment and the attached
drawings for the detailed description of the invention.
[0013] Please refer to FIGS. 2, 3A, and 3B for the tool cabinet
positioning and supporting structure according to the present
invention. The tool cabinet comprises at least one shelf 10 and
four corner bars 20 disposed at four corners of the shelf 10;
wherein the shelf 10 comprises four transversal boards 11, 12
adjacent to the corner bars 20 and a bottom board 13 disposed under
the transversal boards 11, 12. The shelf 10 has two corresponding
transversal boards 11 with two installing surfaces 21, 22, and the
bottom board 13 has a positioning hole 131 at the position of the
installing surfaces 21, 22. A positioning member 30 is disposed
between the shelf 10 and the corner bars 20, and has an installing
surface 31 coupled to the installing surfaces 21, 22 of the corner
bars 20. A limit bolt 32 is extended from the positioning hole 131
of the positioning member 30 to form the positioning and supporting
relation of the shelf 10 and the corner bars 20. A positioning hole
211, 111 is disposed on the installing surfaces 21, 22 of the
corner bars 20 and the transversal boards 11, 12. A fastening
member 40 passes through the positioning hole 211, 111 to
constitute the coupling relation of the shelf 10 and the corner
bars 20. During assembly, it only required to place the shelf 10
between the four corner bars 20. By the limit bolt 32 being
partially extended from the top of the installing surface 31 of the
positioning member 30, the remaining portion at the top of the
installing surface 31 is the blocking surface 33 for supporting the
shelf 10. Therefore, when the bottom board 13 of the shelf 10 uses
the positioning hole 131 to connect the limit bolt 32, the bottom
board 13 is supported by the blocking surface 33. In FIG. 4, it
obviously shows that since there is no component blocking the
transversal boards 11, 12 of the shelf 10 and the installing
surfaces 21, 22 of the corner bars 20, and, therefore it provides a
better attaching effect. Then, the fastening member 40 is used to
pass through the positioning holes 211, 111. The fastening member
40 comprises a screw, a washer, and a nut; wherein the positioning
hole 211 disposed on the installing surfaces 21, 22 is a
rectangular adjusting hole for providing sufficient space to secure
and fine tune the fastening member 40.
[0014] Refer to FIG. 2 for a view of the assembly and compare such
assembly with the prior art as shown in FIG. 1. The corner bars 20
according to the present invention does not come with a bolt
design, and thus maintains a full rigidity. The positioning effect
of the positioning member 30 according to the present invention is
achieved by the bottom board 13 together with the limit bolt 32 and
the positioning hole 131, and thus will not cause any gap.
Furthermore, the design of the blocking surface 33 provides the
effect of supplementing the support of the shelf 10 in addition to
the coupling effect with the fastening member 40.
[0015] While the invention has been described by way of example and
in terms of a preferred embodiment, it is to be understood that the
invention is not limited thereto. To the contrary, it is intended
to cover various modifications and similar arrangements and
procedures, and scope of the appended claims therefore should be
accorded the broadest interpretation so as to encompass all such
modifications and similar arrangements and procedure.
