Description
[0001] This application is a Continuation-In-Part of application
Ser. No. 10/460,309 filed Jun. 13, 2003, the entirety of which is
incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] This invention relates to a storage surface assembly for use
as a shelf for holding storage items in industrial/commercial
applications/environments.
[0004] 2. Background of the Related Art
[0005] Storage shelves used in an industrial/commercial environment
must often bear heavy loads while still maintaining their
structural integrity, as well as resist the twisting and buckling
forces generated when storage items are loaded, unloaded, or moved.
These industrial storage shelves are also subjected to fire codes
requiring some amount of "open area" along the surface of the
shelf, dictated in most cases by the particular environment in
which they will be used, as well as the types of items to be
stored.
[0006] The "open area" required by fire codes is typically 50% of
the surface area of the shelf. This open area requirement was
imposed to allow a fire in the storage area to be more efficiently
contained and extinguished, thus minimizing damage to storage
items. More specifically, a shelf with an adequate amount of open
area allows a fire initiated on a lower shelf to move vertically up
the storage rack, towards the sprinkler, allowing heat to dissipate
more quickly and activating the sprinklers before the fire has
gained significant intensity. Closed shelves (shelves with little
to no open area), which may provide adequate load capacity and
structural integrity, would, on the other hand, form an enclosed
space between shelves, allowing a fire to build in intensity in
that enclosed space, spread horizontally to a neighboring tack of
shelves, and also delay deployment of the sprinkler system,
rendering the sprinkler system significantly less effective in
containing and extinguishing the fire. This 50% open area
requirement poses a unique challenge in providing shelves with
adequate structural integrity at a reasonable cost, while still
meeting this open area requirement. Current solutions, such as
those discussed below, are not adequate.
[0007] Slatted wooden decking, although easily and inexpensively
manufactured, has significant disadvantages in that it is less
durable and mote susceptible to deformation than steel, and more
likely to break under continued loading or changing environmental
conditions. Its most significant disadvantage is that it is highly
flammable.
[0008] Wire mesh decking is a commonly used shelving solution in
industrial/commercial applications. Wire mesh meets the 50% open
area requirement, but, as wire mesh is simply laid across a series
of cross bats, it remains unsupported across a majority of its
load-beating surface, and thus deforms easily. Further, if one of
the support bars is damaged, it cannot be repaired or replaced
without removal of the entire wire mesh, most likely resulting in
replacement of the entire deck as repair would not be cost
effective. Additionally, due to the nature of the surface of wire
mesh, especially after it has deformed, it is difficult to
load/unload/move storage items without damaging the storage items
and/or the wire mesh, as the mesh tends to catch on the storage
items, producing rips, punctures, or impressions. Wire mesh decks
are not easily manufactured or shipped, making them a more costly,
less efficient shelving solution.
[0009] U.S. Pat. No. 5,279,431 to Highsmith et al. discloses a
storage tack with storages surfaces formed by crossbars with tangs
extending from the ends which are then inserted into corresponding
slots in the side beams. However, Highsmith's design is
complicated, difficult and costly to manufacture, and the shelving
system must be used with Highsmith's racking system and cannot be
readily adapted for use in other racking systems. Further, as the
bulk of the load on the storage surface is carried by a very small
tang at the end of the crossbar, Highsmith's design cannot be used
in commercial/industrial applications, where shelves must bear
heavy loads while maintain g their structural integrity.
[0010] Likewise, U.S. Pat. No. 5,628,415 to Mulholland also
discloses a storage rack with safety bars fitted to support beams
by mating tabs and slots. Mulholland's design is complicated,
difficult and costly to manufacture, and is for an entire racking
system whose shelves cannot be readily adapted for use with other
racking systems.
[0011] U.S. Pat. No. 5,199,582 to Halstrick discloses a storage
rack which uses a corrugated plate to form each shelf. Although
Halstrick's design incorporates holes in the corrugated sheet to
allow for a very limited amount of open area, this design could not
meet the 50% open area requirement with out affecting the
structural integrity of the shelf.
[0012] U.S. Pat. No. 6,401,944 to Kircher et al. discloses a
storage rack similar to Halstrick's which does meet the 50% open
area requirement. However, there are several disadvantages
associated with Kircher's design. Kircher's corrugated deck is
expensive to manufacture and ship, increasing cost to the user. If
not properly secured in the rack, the deck elements can spread over
time due to the load applied by the storage items, forcing the rack
to carry more that its design load, thereby compromising the rack's
structural integrity. Similar to wire mesh, the holes, unless
properly finished, tend to shred storage items when they are
loaded, unloaded and moved.
[0013] The above references are incorporated by reference herein
where appropriate for appropriate teachings of additional or
alternative details, features and/or technical background.
SUMMARY OF THE INVENTION
[0014] An object of the invention is to solve at least the above
problems and/or disadvantages and to provide at least the
advantages described hereinafter.
[0015] According to the invention, therefore there is provided a
storage surface assembly for use as a shelf for holding storage
items in industrial or commercial environments. Some amount of the
surface area of the storage surface assembly remains open in order
to provide for adequate circulation of air, heat dissipation, and
water flow, and meet current fire code requirements. The open area
of the storage surface assembly would typically be at least 50% in
order to comply with current fire codes. However, as will become
apparent in the discussion that follows, the storage surface
assembly may be adjusted to meet a variety of open area
requirements, and is not limited to a 50% open area
[0016] Additional advantages, objects, and features of the
invention will be set forth in part in the description which
follows and in part will become apparent to those having ordinary
skill in the art upon examination of the following or may be
learned from practice of the invention. The objects and advantages
of the invention may be realized and attained as particularly
pointed out in the appended claims.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0034] FIG. 1 is a perspective view of a storage surface assembly
according to an embodiment of the invention. The storage surface
assembly 100 of FIG. 1 is constructed of a plurality of traverse
members 20 attached to extension members 30 at attachment members
40 to form a surface area 36. As shown in FIG. 5, at least a
portion of the traverse members 20 are spaced apart from one
another to form open spaces 50. In order to meet current fire code
requirements and in order to provide for adequate circulation of
air, heat dissipation, and water flow, at least 50% of the surface
area 36 remains open via the open spaces 50 formed between the
traverse members 20.
[0035] It is well understood by one skilled in the art that the
amount of surface area 36 that remains open can be either increased
or decreased based on the number of traverse members 20 attached to
a particular part of extension members 30, as well as the
positioning of the traverse members 20 along the extension members
30. In this manner, the storage surface assembly 100 can be adapted
to meet a variety of open area requirements.
[0036] In the embodiment of FIG. 1, the extension members 30
comprise angle irons; however, other shapes and materials may also
be appropriate. The number of traverse members 20 used in the
construction of the storage surface assembly 100 can be adjusted to
suit, for example, the size and load bearing capability requited
for a particular application. However, the open air space must
remain at least 50% for the above described reasons.
[0037] FIGS. 2A-2B are perspective views and FIG. 2C is a cross
sectional view of an extension member 30 employable in a storage
surface assembly in accordance with an embodiment of the invention.
The extension members 30 of the embodiment of FIGS. 2A-2C comprise
angle irons forming an angle .theta. of 90 degrees; however, other
angles may also be appropriate, depending on the particular
application. Likewise, the length a, width b and height c of the
extension member 30 can be varied as necessary, depending, for
example, on a particular application's size and load bearing
requirements.
[0038] FIG. 3A is a perspective view and FIG. 3B is a cross
sectional view of a traverse member 20 employable in a storage
surface assembly in accordance with an embodiment of the invention.
The exemplary traverse member 20 shown in FIGS. 3A-3B are formed in
a ##STR1## shape, with a bottom width f larger than a top width e;
however, the length d, top width e, bottom width f, and height g
can be varied as necessary, depending on, for example, a particular
applications size and load beating requirements. For example, in
the traverse member 20 shown in FIG. 3C, the bottom width is f
substantially equal to the top width e, with the attachment members
40 curved inward. Likewise, a number of different cross sectional
shapes, such as those shown in FIGS. 4A-4S, may also be appropriate
for the traverse members 20.
[0039] As shown in FIG. 5, the traverse members 20 are attached to
the extension members 30 at attachment members 40. The attachment
members 40 serve to both fix the traverse members 20 in position
along the extension members 30, and also to inhibit spreading of
the traverse members 20 due to the load applied by a storage item
and subsequent loss of load bearing capability. The traverse
members 20 which are used in fabricating a single storage surface
assembly must not necessarily be of the same cross sectional shape,
and traverse members 20 of different cross sectional shapes, such
as, for example, combinations of those shown in FIGS. 4A-4S, may be
combined to form a single storage surface assembly.
[0040] The traverse members 20 and extension members 30 can be made
of a variety of different materials. Fabrication material may be
selected based on, for example, load bearing requirements and the
operating environment for a particular application, as well as
cost. For example, in a storage application where humidity and
environmental degradation are factors, both the traverse members 20
and extension members 30 may be made of a galvanized steel to
inhibit material breakdown due to the environmental factors and
subsequent loss of structural integrity. Likewise, in a storage
application where cleanliness and appearance are factors, such as
in a commercial kitchen, both the traverse members 20 and extension
members 30 may be made of a stainless steel. Other materials may
also be appropriate. Traverse members 20 and extension members 30
may not necessarily be fabricated from the same material. However,
attachment methods and environmental effects should be considered
when selecting dissimilar materials for the traverse members 20 and
extension members 30.
[0041] In certain embodiments, the attachment members 40 may extend
outward from the main body of the traverse member 20, such as those
shown in, for example, the embodiments of FIGS. 4A, 4E, 4I and 4M,
and the traverse member 20 is attached to the extension member 30
at the attachment member 40. In other embodiments, the attachment
members 40 may extend inward from an outer surface of the traverse
member 20 towards an inner center of the main body of the traverse
member 20, such as those shown in, for example, the embodiments of
FIGS. 4B, 4F and 4J. In still other embodiments, one attachment
member 40 may extend outward from the main body of the traverse
member 20, while the other attachment member 40 extends inward,
such as those shown in, for example, the embodiments of FIGS.
4C-4D, 4G-4H, and 4K-4L.
[0042] There are numerous ways to effectively attach the traverse
members 20 to the extension members 30. Some of the methods of
attachment well known to those skilled in the art can include, but
are not limited to, welds, screws, rivets, and the like. Attachment
of the traverse members 20 to the extension members 30 to form a
storage surface assembly is not necessarily limited to a single
method of attachment within a single storage surface assembly. A
combination of attachment methods may be used in assembling a
single storage surface assembly, based on the requirements dictated
by a particular application.
[0043] Additionally, with any of the above attachment methods,
individual traverse members 20 can be removed from the extension
members 30 and replaced with new/repaired traverse members 20
without complete disassembly of the storage surface assembly 100 or
replacement of all traverse members 20 while still maintaining the
50% open area. This allows for cost effective repair of the storage
surface assembly 100, and a potentially longer term of use than
related art systems.
[0044] In yet another embodiment, the extension members 30 are
formed as shown in FIG. 2D with a recess 35 which is designed to
mate with an end of the traverse member 20 and allow for slidable
assembly of the traverse member 20 into the recess 35 of the
extension member 30. In this manner, movement of the traverse
member 20 along the extension member 30, as well as spreading of
the traverse member 20 due to a load applied by a storage item is
prevented by the sides of the recesses 35 rather than by the
attachment member 40.
[0045] The extension member 30 can also be formed as shown in FIG.
2E, with slots 36 positioned along a horizontal portion of the
extension member 30 and corresponding to the attachment members 40
of the traverse member 30, allowing for slidable assembly of a
single traverse member 20 such as those shown in, for example,
FIGS. 4A-4M, into the slots 36 of the extension member 30, or a
"stack" of traverse members as shown in, for example, FIGS. 2F-2H,
and discussed below. A flat plate 31 is then attached to a bottom
surface of the extension member 30, with the attachment members 40
positioned therebetween, thus securing the traverse members 20 in
place.
[0046] The spacing of the slots 36 along the horizontal portion of
the extension member 30 may be adapted to meet the requirements of
a number of different storage applications, and the slots 36 need
not be equally spaced. Additionally, as shown in FIGS. 2F-2H, the
attachment member 40 of a first traverse member 20 can be placed on
and aligned with an attachment member 40 of a second traverse
member 20, forming a "stack" of attachment members 40. The stacked
attachment members 40 of the first and second traverse members 20
can then be slidably inserted into the slots 36. Stacked traverse
members 20 need not necessarily have the same cross sectional shape
or attachment member 40 orientation. For example, the traverse
member 20 shown in FIG. 4A can be stacked with any of the traverse
members 20 shown in FIGS. 4B-4M and then slidably inserted into
slot 36. Likewise, the traverse member 20 shown in FIG. 4B can be
stacked with any of the traverse members 20 shown in FIGS. 4A,
4C-4E, 4G-4I, and 4K-4M, and so on.
[0047] Both the single and the stacked slidable attachment methods
discussed above may be employed with a variety of different
traverse member 20 combinations, and traverse members 20 need not
all be of the same shape in a single storage surface assembly.
[0048] A snap fit procedure could also be employed in attaching
traverse members to extension members, as shown in FIGS. 2I-2M.
FIG. 2I shows a snap fit extension member 32 with a vertical
extension 33 formed along its length, and notches 33a and 33b
corresponding to the cross sectional shape of attachment members
23a and 23b of a snap fit traverse member 23 cut into the vertical
extension 33 at predetermined positions along the length of the
snap fit extension member 32. When attachment members 23a and 23b
are aligned with notches 33a and 33b, a downward force applied to
the snap fit traverse member 23 would cause the attachment members
23a and 23b to temporarily contract as they pass through the more
narrow portion of the notches 33a and 33b, and return to their
original shape once they enter the wider portion of the notches 33a
and 33b, thus securing the snap fit traverse member 23 to the snap
fit extension member 32. A similar procedure would be used to snap
fit the snap fit traverse member 23 to the snap fit extension
member 32 shown in FIGS. 2J-2L.
[0049] FIG. 2M shows a snap fit extension member 32 with a vertical
extension 33 formed along its length. Notches 33c and 33d
corresponding to the cross sectional shape of attachment members
23c and 23d of a snap fit traverse member 23 are cut into the
vertical extension 33 at predetermined positions along the length
of the extension member 32. FIG. 2N shows this snap fit traverse
member 23 secured to this snap fit extension member 32. The notches
33c and 33d are specifically shaped to accommodate the curved shape
of the attachment members 23c and 23d. Each notch includes a
protrusion 33e which engages a corresponding slot 23e formed in the
side wall of the snap fit traverse member 23 as the attachment
members 23c and 23d are directed downward into the notches 33c and
33d, thus securing the snap fit traverse member 23 to the extension
member 32, as shown in FIG. 2N. Although the extension members 32
and traverse members 23 shown in FIGS. 2M-2N include two
protrusions 33e and two corresponding slots 23e formed in each end
of each traverse member 23, it is well understood that these
elements could also be effectively secured with a single protrusion
33e and slot 23e at either one end or each end of the traverse
member 23. Other means of attaching the traverse members to the
extension member may also be appropriate based on the application,
materials used, and other factors which may effect the assembly's
performance.
[0050] FIG. 5 is a top view of a storage surface assembly according
to an embodiment of the invention. The storage surface assembly of
FIG. 5 includes a plurality of traverse members 20 extending
between two extension members 30. The traverse members 20 are
spaced apart from one another forming open spaces 50. In FIG. 5,
the traverse members 20 are shown substantially equally spaced
along the extension members 30. However, the amount of open space
50 between traverse members 20 may be varied as shown in FIGS.
6A-6B, and various traverse member 20/open area 50 spacing
combinations may be appropriate, based, for example, on the desired
configuration and/or application. For example, the traverse members
20 may be grouped, as in the embodiment of FIG. 6B, with the open
space 50 between groups in these alternative configurations
adjusted to conform to the open area requirement as necessary. In
this manner, the grouping and spacing of traverse members 20 along
the extension members 30 may be adjusted to meet individual user
requirements without redesign of the base components of the storage
surface assembly 100.
[0051] FIG. 7 is a front view of a rack beam assembly according to
an embodiment of the invention incorporating a storage surface
assembly according to the invention. The rack beam assembly of FIG.
7 includes a storage surface assembly 100 installed in a set of
rack beams 200. The tack beams 200, designed to fit one of many
standard commercial/industrial tacking systems, may be specified by
the user and are well known in the industry. FIG. 8 is a
perspective view of the tack beam assembly 300. As shown in FIG. 8,
the tack beam assembly 300 may be installed in a
commercial/industrial racking system 400.
[0052] As evidenced by the numerous traverse member configurations,
attachment methods, and grouping/spacing configurations discussed
herein, the various embodiments of the invention provide clear
advantages over the related art with an easily and inexpensively
manufactured and distributed shelving solution that exhibits
adequate load beating capability and structural integrity while
still meeting the 50% open area requirement, and which can be
easily adapted to meet specific user needs.
[0053] The foregoing embodiments and advantages are merely
exemplary and are not to be construed as limiting the invention.
The present teaching can be readily applied to other types of
apparatuses. The description of the invention is intended to be
illustrative, and not to limit the scope of the claims. Many
alternatives, modifications, and variations will be apparent to
those skilled in the art. In the claims, means-plus-function
clauses are intended to cover the structures described herein as
performing the recited function and not only structural equivalents
but also equivalent structures.
