Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit under 35 U.S.C.
.sctn.119(e) of prior U.S. Provisional Application No. 601256,816
filed Dec. 19, 2000: which is hereby incorporated by reference.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] This invention has been created without the sponsorship or
funding of any federally sponsored research or development
program.
BACKGROUND OF THE INVENTION
[0003] This present invention is directed to a supporting apparatus
for holding and storing a large number of electronic components of
the type generally referred to as "rack mounted". These electronic
components which typically include computers, network servers,
electronic network components, such as routers, bridges, switches
and hubs, and computer storage devices, are generally configured so
that numerous of the components can be stored in a common storage
system. The electronic components have flanges extending to the
right and left of the front face of the component so that the
component can be bolted to the supporting apparatus to locate the
device in the component within the supporting apparatus.
[0004] A typical supporting apparatus for holding and storing
electronic components is a vertically extending rectangular frame
into which the individual electronic components can be bolted. The
frame is supported by two horizontal feet which extends forward and
rearward of the frame.
[0005] A variation of the basic frame for supporting and storing
electronic components is referred to in the trade as a
"double-sided component rack". In the storage rack version of the
storage frame, a second rectangular frame component is positioned
parallel to and rearwardly of the first frame. This enables the
back ends of the electronic components to be held in position to
provide a more stable system for storing the components. Also, the
rear frame is adjustable relative to the front frame to selectively
change the distance between the two frame components.
[0006] A still further variation of the basic frame concept is a
supporting apparatus known as a "component cabinet". The cabinet
enables the electronic components to stored within a container for
securing and cleanliness purposes. Traditionally, these cabinets
are made from a Mig/Tig welded frame with the structural elements
running vertical along the four corners and horizontal around the
base and top. The doors and sides then fasten into openings on all
four sides. This Mig/Tig welding process is slow and expensive.
Once the cabinet is welded, it is bulky to store, more difficult to
paint and more expensive to ship.
[0007] The traditional forms of supporting apparatus for holding
electronic components were designed to minimize the cost of
shipping in the so-called "knocked down" condition, that is, the
supporting apparatus was manufactured in a totally disassembled
state, shipped to the site of use, and then assembled on the site.
The reasonableness of the traditional designs for the supporting
apparatus, which were primarily "bolt-together" designs, was that
the cost of shipping was relatively high, and the availability of
low cost assembly personnel at the installation site was assumed
and typical. Furthermore, the dynamics of the installation process
and facilities were such that the time required to construct the
storage systems at the installation site did not interfere with
other scheduling.
[0008] One of the things that has happened in recent times in
connection with the market for electronic component storage is that
the market has become dominated by large component facilities which
typically represent the computer equipment facility for a large
computer network, or sometimes represent worldwide global network
servers for providing web page service. Another major application
is large computer data storage warehouses which are facilities
filled with electronic computer storage devices which can be
accessed using networks. These type of facilities typically involve
huge numbers of electronic components all of which have to be
appropriately supported and wired together. The process of
assembling the supporting apparatus and securing the electronic
components typically involves relatively highly paid technicians
who are primarily involved in the installation of the electronic
computer network equipment and are, therefore, relatively expensive
sources of assembly labor. Furthermore, the time table for
installing these types of facilities is often very short and the
time taken to conduct bolt-together assemblies is sometimes a
serious problem. In addition, the clearance in the untapped or
unthreaded holes for the bolts very often causes the frame to be
out of square when the supporting apparatus is assembled.
[0009] These and other difficulties experienced in the prior art
supporting apparatus for holding and storing electronic components
have been obviated by the invention.
[0010] It is, therefore, a primary object of the invention to
provide a storage cabinet for holding and storing electronic
component which can be shipped in a relatively low volume
condition, but which can be very easily and quickly assembled at
the assembly site.
BRIEF SUMMARY OF THE INVENTION
[0011] In general, the invention consists of a storage cabinet for
electronic components. The storage cabinet is made up of removably
attachable components including: a rectangular base, a rectangular
vertical front frame, a rectangular vertical rear frame, a pair of
side walls, a rectangular cover, a door hingedly connected to the
front frame, and a door hingedly connected to the rear frame. Four
apertures vertical support bars are adjustably mounted on the inner
sides of side frames for supporting the electronic components. More
specifically, the side walls are mechanically interlocked with the
front and rear frames. The side walls are secured to the base and
cover by nuts and bolts.

DETAILED DESCRIPTION OF THE INVENTION
[0031] Referring first to FIGS. 1 and 2, the storage cabinet of the
present invention is generally indicated by the reference numeral
20 and is made up of a plurality of component parts which can be
assembled and disassembled. The component parts of cabinet 20
comprise a base, generally indicated by the reference numeral 22, a
top cover, generally indicated by the reference numeral 24, a front
rectangular frame, generally indicated by the reference numeral 26,
a rear rectangular frame, generally indicated by the reference
numeral 28, a pair of identical side walls, generally indicated by
the reference numeral 30, a door 32, and four support bars 34.
[0032] Referring particularly to FIGS. 2, 14, and 15 the base 22
comprises a rectangular vertical wall, generally indicated by the
reference numeral 33, reinforced by a plurality of tubular bars.
The rectangular vertical wall comprises a front wall portion 35, a
rear wall portion 36 and a pair of identical side wall portions 37.
The upper portion of each side wall portion 37 has a plurality of
horizontal apertures 39. Each side wall portion 37 is reinforced by
a tubular bar 40 which has a square cross section. Each of the
front and rear wall portions 35 and 36, respectively, is reinforced
by a tubular bar 38 which has a rectangular cross section. A
vertical cylindrical tube 42 is located in each inside corner where
the bars 40 intersect the bars 36 and 38. The bars 40 are fixed to
the walls 37, the bars 38 are fixed to the walls 36 and 35, and the
tubes 42 are fixed to the bars 38 and 40, i.e., by welding. The
tubes 42 are adapted to receive casters 44 in a conventional
manner.
[0033] Referring particularly to FIGS. 2-4, the cover 24 has a
horizontal planar top wall 46, a vertical front wall 48, vertical
rear wall 50 and pair of vertical side walls 52. Each of the side
walls 52 has a plurality of holes 54.
[0034] Referring particularly to FIGS. 2, and 6-8, the front
rectangular frame 26 comprises a pair of rectangular tubular bars
56 fixed at their upper ends to a upper cross bar 58. The bars 56
are fixed at their lower ends to a lower cross bar 60. Each of the
cross bars 58 and 60 is a square tube which is fixed to the side
bars 56, i.e., by welding. The upper and lower walls of each of the
bars 58 and 60 has an aperture 62 at each end of the bar. The
rearwardly facing wall portion 64 of each side bar 56 has a
terminal end 66. The outwardly facing side wall portion 68 of each
side bar 56 has a free end portion 70 that extends inwardly at a
right angle to the wall portion 64 to define with the wall portion
64 a slot 72. The rear frame 28 is identical to the front frame
26.
[0035] Referring particularly to FIGS. 10-13, each side wall 30
comprises a planar vertical wall 74 and a plurality of horizontal
tubular bars 84 fixed, i.e. by welding, to the inwardly facing side
of the wall 74. The wall 74 has an L-shaped flange, generally
indicated by the reference numeral 76, along each side edge of the
wall 74. Each flange 76 consists of first portion that extends
transversely of the wall 74 inwardly of the cabinet and a terminal
end 80 that is parallel to the wall 74. Each bar 84 has an
elongated slot 86 in the inwardly facing wall of the bar.
[0036] Referring to FIG. 9, the door 32 has a pair of L-shaped
hinge pins, generally indicated by the reference numeral 90,
slidably mounted in a housings 93 at the upper and lower corners
along one side of the door. Each hinge pin 90 has a vertical
portion 94 that is biased by a spring, not shown, within the
housing so that the terminal end extends beyond the respective
upper and lower ends of the door. The opposite end of each pin 90
has horizontal portion 96 which enables to a person to move the pin
90 against the spring bias so that the opposite end of the pin is
drawn inwardly of the outer periphery of the door. The door 32 has
a bore 88 for receiving a conventional latching mechanism,
generally indicated by the reference numeral 89.
[0037] Referring to FIGS. 16-18, there is illustrated one of the
support bars 34 commonly referred to in the trade as a "rack
mounting angle". The support bar 34 has a C-shaped cross section
and includes a side wall 97, a front wall 99, and a rear wall 98.
Each of the rear and front wall of the bar 34 has a plurality of
square apertures 100. The side wall 97 has a plurality of spaced
apertures 101.
[0038] The four support bars 34 are pre-assembled with the side
wall 30 before the cabinet components are shipped to the customer's
assembly site. Two of the support bars are positioned against the
tubular bar 84 of each side wall 30 so that the bars 34 extend
vertically and the front wall 99 of each bar faces forwardly. The
apertures 101 are aligned with the slots 86 of the bars 84. This
enables the bars 34 to be secured to the bars 84 by extending bolts
through the apertures 101 and threading the bolts into flat nuts
located within the bars 84. The nuts are wider than the slots 86.
This enables the bars 34 to be fastened by the bolts in fixed
positions relative to the side walls 30. However, the bars 34 can
be adjusted rearwardly and forwardly to any desired position
relative to the side walls 30 by loosening the bolts.
[0039] The components of the storage cabinet 20 can be packed in a
relatively small container for shipment to an installation site.
The cabinet 20 is assembled at the site by positioning the front
and rear rectangular frames 26 and 28, respectively, on top of the
bar 38 so that the walls 64 of the vertical bars 56 face toward
each other as shown in FIG. 2. The side walls 30 are coupled with
the frames 26 and 28 by positioning each side wall so that the
bottom edge of the side wall is vertically aligned with the top
edges of the frames 26 and 28 parallel with the side wall portions
37 of the base 22. The first portions 78 of the flanges 76 are
inserted into the slots 72 so that the terminal ends 80 of flanges
76 are inside of terminal ends 70 of walls 68. The side walls 30
are then moved downwardly relative to the frames 26 and 28 so that
the walls 30 are mechanically interlocked with the frames 26 and 28
and the aperture 82 are aligned with the apertures 39.
[0040] The cover 24 is placed on the upper edges of the frames 26
and 28 and the side walls 30 so that the vertical side walls
overlap the upper ends of the frames and side walls. The cover is
positioned so that the side walls 54 extends along the walls 74 and
the apertures 82 are horizontally aligned with the apertures 54.
The side walls 30 are secured to the base 22 and the cover 24 by
fasteners 83 such as machine screws or nuts and bolts. The door 32
is connected to the front frame 26 by inserting the vertical
portions 94 of pins 90 into the vertically opposed apertures 62 at
one end of the bars 58 and 60. The apertures 62 at the right side
of the frame 26 are utilized for a right-hand door opening. For a
left-hand door opening, the door 32 is rotated end over end and the
pins 90 are inserted into the apertures 62 at the left-hand ends of
the bars 58 and 60.
[0041] The latch 89 is applied to the door 32 and the casters 44
are applied to the tubes 42 to complete the assembly. A second door
32 is applied to the rear frame 28 in the same manner as the
application of door 32 to the front frame 26.
