Abstract
A rack comprises at least one wire mesh panel comprising a first array of parallel wires and a second array of parallel wires, the wires of the first and second arrays being in transverse, angular relation and being bonded to each other at at least a substantial number of wire crossing points. The panel defines opposed, parallel side edges which are substantially defined by first individual wires of the first array. Third wires are respectively bonded to the panel and positioned parallel to and adjacent to the first individual wires of the first array. The third wires are spaced from the first individual wires by crossing wires of the second array. A plurality of such wire mesh panels may be secured together at their opposed parallel edges by clamp members to provide a modular rack system. Hanger wires may be carried by clamp members, each end of the hanger wires defining a transversely (upwardly) extending wire portion terminating in a hanger hook so that the rack may be hung from a site above the rack.
Description
BACKGROUND OF THE INVENTION
This invention relates to a rack which is mounted typically from a rafter, which may also hold a solid ceiling, or may be open. The rack is made of a mesh of stiff wires, and may comprise a group of modular units which may be secured together to provide a rack or racks of varying size. The entire rack system may be pre-assembled and lifted for easy installation into pre-installed attachment members. The system is very flexible and forgiving as to the spacing of the pre-installed attachment members. Also, the system will tend to move rather than break if it is bumped, since it is held from vertically mounted hanger wires which may rotate to a certain extent with respect to the rack, permitting the rack to swing rather than break. The rack system is inexpensive, and capable of holding large loads.
DESCRIPTION OF THE INVENTION
This invention relates to a rack which comprises at least one wire mesh panel which, in turn, comprises a first array of parallel wires and a second array of parallel wires, both of the wire arrays being relatively stiff. The wires of the first and second arrays are in transverse, angular relation, being bonded to each other at at least a substantial number of wire crossing points, by welding or the like.
The wire mesh panel defines opposed, parallel side edges which are substantially defined by first individual wires of the first array. Third wires are respectively bonded to the panel, being positioned parallel to and adjacent to the first individual wires of the first array, i.e., those individual wires that define the opposed, parallel side edges. The third wires are spaced from the first individual wires by crossing wires of the second array.
Thus, the opposed, parallel side edges of the wire mesh panel which comprises the rack are generally defined by a pair of parallel wires comprising a first individual wire and a third wire, separated by the second array of wires, typically the ends of the wires of the second array.
Often, a plurality of the wire mesh panels described above may be connected together along their opposed parallel side edges by a plurality of clamp members. These clamp members respectively enclose the first individual wires of the first array and the adjacent third wires, to provide extra strength to the connection. The clamp members may retain a hanger wire, which hanger wire is positioned below the wires of the second array, parallel to the wires of the first array. The hanger wire extends substantially the length of the wire mesh panel, parallel to the opposed, parallel side edges. Each end of the hanger wire preferably defines a transversely extending wire portion terminating in a hanger hook, to permit hanging from a ceiling, typically a rafter which defines the ceiling and may also support a solid, horizontal ceiling if desired. Preferably, several such hanger wires are present, one on each side of the wire mesh panel or preferably an array of connected wire mesh panels.
It is also preferable for the clamp members to each comprise a first member which is substantially U-shaped in cross section, and a separate, second member which is substantially S-shaped in cross section. The first and second members are bolted together. Each of the S-shaped members defines a trough which receives a hanger wire, described above, in a position below the wires of the second array and parallel to the wires of the first array. Thus, each of the hanger wires may support the wires of the second array from the bottom if desired. Alternatively, heads of the bolts which hold the first and second members of the clamp member together may engage and prevent the hanger wire members from rising out of the trough when the wire mesh rack is supported by the hanger members. Also, the clamp members may surround and secure a pair of the opposed, parallel side edges of adjacent wire mesh panels, thus enclosing a first individual wire and a third wire of each of the panels for strong securence together of the respective wire mesh panels, to form a modular rack comprising two or more of such wire mesh panels connected together.
Thus the vertically mounted rack of this invention can be hung from brackets on rafters, or other elevated sites, being quite forgiving relative as to precise spacing of the brackets, and being capable of a measure of movement if bumped so that the rack swings rather than breaking in such a circumstance. This provides a new and useful rack for garages, workshops, and other indoor areas for added storage space, while the rack is relatively light and of simple, inexpensive construction, as well as being of variable size.

DESCRIPTION OF SPECIFIC EMBODIMENTS
Referring to the drawings, a modular rack
10
is shown, being made up of several wire mesh panels
12
, which are secured together at respective opposed, parallel side edges
14
.
Each wire mesh panel comprises a first array of parallel wires
16
and a second array of parallel wires
18
. The respective wires of the first and second arrays
16
,
18
are seen to be substantially perpendicular to each other, although, if desired, other angles such as 45° or 60° may be used. The wires of the respective first and second arrays
16
,
18
may be bonded to each other by conventional welding at least at a substantial number of wire crossing points.
The respective wires of arrays
16
,
18
, have a diameter, for example, of about a quarter inch each, to be stiff and strong.
In accordance with this invention, third wires
20
are respectively bonded to the panel at crossing second wires
18
, the third wires being positioned parallel to and adjacent to the first individual wires
16
a
of the first array, being typically positioned at the edge of each panel along with first individual wires
16
a
of the first array. This defines the side edges
14
along with third wires
20
in this embodiment. This can be seen in
FIG. 3
, for example, in which the opposed, parallel side edges of joined panels are defined by a first individual wire
16
a
of the panel's first array
16
and a parallel third wire
20
, the respective wires
16
a,
20
being separated by the crossing wires of the second wire array
18
.
The respective wire mesh panels
12
are connected together in this manner along the opposed parallel side edges defined by wires
16
a,
20
by several spaced clamp members
22
, which hold the respective panels together, enclosing respective third wires
20
and first individual wires
16
a
of the pair of wire mesh panels together in the clamp
22
in a generally rectangular array, with each of the wires
20
of adjacent panels being separated from wires
16
a
by the perpendicular wires of the second array
18
. This provides a strong, secure connection between the respective wire mesh panels
12
, with the panel edges defined by wires
20
,
16
a
having substantially increased strength because of the extra wire
20
.
Each of the respective clamp members
22
comprise a first member
24
which is substantially U-shaped in cross section (
FIG. 2
) and a second member
26
, which is substantially S-shaped in cross section, with one end being extended parallel to the central portion of the S-shaped cross section so that the extended end
28
defines a trough
30
. First and second members
24
,
26
are bolted together with bolts
32
into the configuration as shown in FIG.
2
. In this configuration, the respective sides of two wire mesh panels are held together by the clamping of their respective first individual wires
16
a
and the third wires
20
, the wires being held in a cross-sectional rectangular array, with wires
20
being spaced from wires
16
a
by the wires of second array
18
.
Trough
30
, defined by S-shaped second member
26
, carries a horizontal portion
34
a
of a hanger wire
34
in a position below the wires of second array
18
. The section of hanger wire
34
which occupies trough
30
is parallel to the wires of first array
16
,
16
a.
Each of hanger wires
34
carries a hook
38
at its outer end, which hook can engage an aperture
40
of a bracket
42
, which bracket may be mounted on a rafter or other solid site for mounting above the rack
12
. While not shown for clarity, each of hooks
38
may connect to a separate attached bracket
42
, which brackets may be mounted by screws
46
in a conventional manner. Because of the inherent flexibility of hanger wires
34
, the placement of brackets
40
along a rafter or other attachment site is not very critical, so that the rack
12
of this invention can be easily installed. Also, if rack
12
is struck by the top of a moving vehicle, its tendency is more to swing and bend rather than to break, while retaining the load carried on the rack.
The horizontal section
34
a
of hanger wire
34
may rest underneath the wires of second array
18
in load carrying manner. Alternatively, the heads of bolts
32
and the width of extended portion
28
of second clamp section
26
may retain the horizontal portions
34
a
of hanger wires
34
in spaced relation from second wire array
18
, if desired, and either way, strong load-bearing characteristics can be achieved.
The respective side edges
48
of rack
12
will normally also be secured by clamp members
22
with an attached, retained hanger wire
34
. But this structure is not shown for clarity of disclosure, so that the structure and relationship of wires
16
a,
18
,
20
can be clearly seen.
Thus, a modular rack
12
is disclosed, which may comprise one or any plural number of connected wire mesh panels
12
, having attached hanger wires which may be connected at their outer ends through hooks
38
or the like to an upper attachment point, such as a ceiling, which term is intended to include open rafters or any other upper surface under a roof. The modular rack is inexpensive, very strong, easy to install, and resistant to damage by collision with the top of a moving vehicle or the like.
The above has been offered for illustrative purposes only, and is not intended to limit the scope of the invention of this application, which is as described in the claims below.
