Description
CLAIM FOR RIGHT OF PRIORITY UNDER 35 U.S.C. .sctn.119(b)
[0001] This present application claims all available benefit, under
35 U.S.C. .sctn. 119(b), of Utility Patent Application No. GB
0513335.0 filed in the United Kingdom on Jun. 30, 2005.
FIELD OF THE INVENTION
[0002] The present invention relates to an apparatus for use in
protecting assets, such as buildings and the like, from damage
caused by extreme weather, particularly high wind conditions.
BACKGROUND TO THE INVENTION
[0003] Damage or loss of property, such as permanent buildings,
mobile accommodation such as caravans, vehicles, boats ashore,
aircraft or the like often occurs during extreme weather conditions
where high wind-generated forces exist. For example, items may be
displaced from their intended location if their weight and/or
anchorage is insufficient to resist the loads induced by high
winds. However, it is often the case that damage to structures,
such as permanent buildings, is initiated at their roof portion due
to the creation of adverse pressure differentials. That is, high
velocity wind displaced over the roof portion of a structure will
create a low static air pressure above the structure relative to
the internal air pressure of the structure. Moreover, air will be
forced into the structure via any opening, such as ventilation
openings or the like, resulting in an increasing internal static
air pressure. The roof portion will accordingly be subjected to a
net lift force. If the resultant lift force is of a magnitude
greater than the combined weight of the roof and the resistance
offered by the fixtures securing the roof portion to the structure,
then separation from the structure will occur. Upon initial
separation, the underside of the roof portion will be directly
exposed to the high winds such that the high dynamic air pressure
will impart a significant force on the roof portion, which may
contribute towards the roof portion catastrophically detaching from
the structure.
[0004] In many instances, the roof portion provides considerable
integrity to the structure as a whole, and loss or damage to the
roof may significantly compromise the strength of the structure.
Accordingly, if a roof becomes separated from a structure, as
described above, the dynamic air pressure may be sufficient to
cause the remaining structure to collapse.
[0005] Various systems have been proposed to alleviate the problems
caused by high wind-generated forces acting on a building or mobile
home or the like. For example, U.S. Pat. No. 4,144,802 discloses a
hurricane/tornado building protection system which provides
increased and specially adapted ventilation to accommodate extreme
changes in atmospheric pressures. Additionally, U.S. Pat. No.
6,088,975 teaches a hurricane protection system for mobile homes
and small buildings, wherein the system comprises a storm shield
having a number of embedded cables. The storm shield, in one
embodiment, extends from the edge of a roof and is anchored within
a channel formed at ground level, and in an alternative embodiment
extends from one side of the building, over the roof, and is
subsequently anchored within a ground channel on the opposite side
of the building.
[0006] Other systems known in the art comprise nets or perforated
sheets which are secured over a building or other object. Examples
of such systems are disclosed in references CA 2,131,405; U.S. Pat.
No. 6,453,621; and FR 2 691 736. However, the use of netting or
perforated sheets serves only to provide a physical holding or
restraining force to maintain the object, or parts of the object,
in a single location. There will be little or no effect on the
overall aerodynamics of the object.
SUMMARY OF THE INVENTION
[0007] According to a first aspect of the present invention, there
is provided an apparatus for use in protecting an asset. The
apparatus includes at least one sheet member adapted to be located
over an upper surface of an asset and secured between first and
second anchoring means and a first connecting assembly adapted to
be coupled between one of the first and second anchoring means and
the sheet member.
[0008] Preferably, the apparatus is adapted for use in protecting
an asset from high wind induced loading which may be present during
extreme weather conditions, such as storms, including hurricanes
and tornadoes.
[0009] The apparatus may be adapted to protect any suitable
physical asset, such as a structure or the like, and may include
permanent buildings, temporary buildings or structures, mobile
homes, caravans, vehicles, trailers, boats ashore, aircraft or the
like.
[0010] Advantageously, in use, the sheet member may be secured over
at least a portion of an asset to provide protection from, for
example, high wind generated forces. That is, the sheet member may
advantageously deflect wind over or around the asset, thus reducing
the wind induced forces imparted thereupon. Additionally, the sheet
member may assist to minimise any pressure differential created
externally and internally of the asset which may otherwise cause
significant damage, for example to a roof portion of a building
such as a dwelling or the like. The sheet member therefore has
significant advantages over the use of perforated sheets or netting
which provide little or no effect on the aerodynamics of the asset.
Furthermore, by virtue of securing the sheet member over the asset
and between first and second anchoring means, the apparatus of the
present invention will assist to retain the asset at its intended
location, and provide an increased retaining force to parts of the
asset, such as a roof of a building or the like. Additionally, the
apparatus may assist to prevent an asset from being damaged by
airborne debris during high wind conditions, for example.
[0011] Preferably, the first connecting assembly comprises at least
one anchor engaging member adapted to be secured at one end to the
sheet member, and at an opposite end to anchor means. Preferably,
the anchor engaging member comprises a flexible elongate element,
such as a rope, cable, webbing or the like. Alternatively, the
anchor engaging member may comprise a substantially rigid element,
such as a rod or bar or the like, of any suitable material, such as
metal or the like.
[0012] Beneficially, the connecting assembly may comprise a
harmonic damper adapted to eliminate or at least reduce, for
example, wind induced vibrations and harmonics. In a preferred
embodiment, the harmonic damper is coupled to the anchor engaging
member.
[0013] The anchor engaging member may be directly secured to the
sheet member, for example via an eyelet, lug, bracket or the like
in or on the sheet member.
[0014] Preferably, the first connecting assembly further comprises
at least one connecting member adapted to be coupled to an end
portion of the sheet member, wherein the anchor engaging member is
adapted to be secured to the sheet member via said connecting
member. Preferably, the connecting member is rigid. Advantageously,
the connecting member may be elongate and is preferably of a length
substantially equal to the width of the end portion of the sheet
member to which said connecting member is to be coupled. This
arrangement advantageously provides support to the sheet member
across the entire width thereof, assisting to ensure creation of
uniform tension across the sheet member when secured between first
and second anchor means, and substantially minimising or
eliminating turbulence induced waves across the sheet member when
exposed to high winds. Alternatively, the connecting member may be
of any suitable length to be secured to an end portion of the sheet
member.
[0015] The anchor engaging member may be secured to the connecting
member via an eyelet, lug, bracket, threaded coupling or the like.
Alternatively, the anchor engaging member may be secured to the
connecting member via an inter-engaging mating profile defined
between the anchor engaging member and sheet member.
[0016] In one embodiment the anchor engaging member may be secured
to the connecting member via a profiled eyelet or loop mating
arrangement. Advantageously, the connecting member is profiled in
lateral cross-section and the anchor engaging member comprises a
loop, eyelet or the like adjacent one end thereof, wherein the
eyelet defines a profile substantially complementary to that of the
connecting member. The profile may be asymmetrical such that, in
use, the connecting member may only be received within the eyelet
when the member and eyelet are relatively positioned in a
particular orientation. The connecting member may define a notch at
a location in the outer surface thereof. Advantageously, in use,
the eyelet and connecting member may be relatively orientated such
that the eyelet may be slid onto the connecting member and aligned
with the notch formed in the outer surface thereof, and the eyelet
then subsequently rotated about the connecting member. Accordingly,
due to the asymmetry of the profiles, a portion of the eyelet may
become located within the notch in the connecting member thus
preventing relative lateral motion of the eyelet along the
connecting member. Once the connecting member and eyelet, and thus
anchor engaging member, are appropriately coupled together via the
profile and notch arrangement, the anchor engaging member may then
be secured to appropriate anchoring means. In embodiments of the
present invention the notch and anchor means are orientated to as
to bias or pull the eyelet into the notch thus providing a secure
connection.
[0017] Advantageously, the anchor engaging member may be coupled to
an anchor means via a hook arrangement. For example, the anchor
means may comprise an eyelet, loop, lug, bracket or the like, and
the anchor engaging member may comprise a hook portion, shackle or
the like, or vice-versa. Alternatively, the anchor engaging member
may be coupled to an anchor means via a clamping arrangement,
threaded arrangement or the like.
[0018] Preferably, the first connecting assembly comprises two or
more anchor engaging members.
[0019] Preferably, the connecting member is adapted to be
releasably coupled to the sheet member. This arrangement
advantageously provides a modular apparatus permitting the sheet
member and connecting assembly to be separated when required, for
example, when one of the sheet member and connecting assembly is
required to be replaced or removed for repair, inspection, quality
assurance verification/testing or the like. Furthermore, modularity
of the apparatus facilitates efficient storage of the apparatus
when not in use.
[0020] Alternatively, the connecting member may be adapted to be
permanently secured to the sheet member.
[0021] The connecting member may be adapted to be coupled to the
sheet member by, for example, bolting, riveting, clamping, adhesive
bonding or the like. Alternatively, and in a preferred embodiment,
the connecting member and sheet member define inter-engaging
profiles adapted to be mated together and engaged to couple the
sheet member to the connecting assembly. In one embodiment of the
present invention, one of the connecting member and sheet member
defines a female portion, and the other of the connecting member
and sheet member defines a corresponding male portion. The female
portion may comprise a channel, whereas the male portion may
comprise a suitably profiled element adapted to be received within
said channel. In a preferred embodiment of the present invention,
the channel is defined by a bore in combination with a slot merging
with the bore and extending along the entire length thereof. The
bore may be circular, ovoid, square, rectangular or the like in
cross-section. Preferably, the slot is of a width smaller than that
of the corresponding male portion, thus preventing inadvertent
separation of the male and female portions when coupled together.
In this arrangement, the female portion is adapted to receive the
male portion from one end of the female portion. In a preferred
embodiment of the present invention, the cross-sectional profile of
the female portion is substantially C-shaped. Preferably, the
connecting member defines the female portion and the sheet member
defines the male portion.
[0022] Alternatively, the connecting member may be coupled to the
sheet member via a dove-tail arrangement, or equivalent mating
structure or the like.
[0023] The connecting member may be of a metal or metal-alloy
material, such as an aluminium alloy, steel or the like.
Alternatively, the connecting member may be formed of a polymeric
material, composite material or the like. In one embodiment of the
present invention, the connecting member may be formed by
extrusion. Alternatively, the connecting member may be cast.
Alternatively, or additionally, the connecting member may be
machined.
[0024] Advantageously, the connecting member may define an
aerodynamically profiled or streamlined surface adapted to minimise
drag induced forces applied thereto when exposed to high wind
conditions, and assisting to limit turbulent flow across the sheet
member which may otherwise cause flow induced vibrations to
propagate across said sheet member, resulting in increased cyclic
loading on the connecting assembly and anchor means which may lead
to premature material fatigue. Advantageously, the connecting
member may be substantially aerofoil-shaped. In embodiments of the
present invention the connecting member may be tear-shaped,
pear-shaped or the like.
[0025] In embodiments of the present invention, a plurality of
connecting members may be provided.
[0026] Beneficially, a second connecting assembly may be provided
and adapted to be coupled between the other of the first and second
anchoring means and the sheet member. The second connecting member
may be similar to the first connecting member. Preferably, the
second connecting assembly comprises an anchor engaging member
adapted to be secured between anchor means and the sheet member. In
a preferred embodiment of the present invention, the second
connecting assembly comprises a single anchor engaging member. This
arrangement is particularly advantageous where the first connecting
assembly comprises two or more anchor engaging members in that a
substantially uniform tension will be achieved in the sheet member
when secured between anchoring means, assisting to minimise
turbulence induced waves across the sheet member.
[0027] Preferably, one or both of the first and second connecting
assemblies further comprises a tensioning system adapted to apply
tension across the sheet member when secured between first and
second anchor means. The tensioning system may comprise a ratchet
tensioner, turnbuckle, toggle tensioner or other over-centre
tensioning device, or the like.
[0028] Preferably, the apparatus comprises a plurality of sheet
members adapted to be coupled together, preferably end-to-end, to
form a canopy structure. In this arrangement, the first connecting
assembly is adapted to be coupled to one sheet member, and the
second connecting assembly is adapted to be coupled to another
sheet member.
[0029] Advantageously, the sheet members are adapted to be
releasably coupled together, preferably via an interconnecting
assembly. By permitting the sheet members to be releasably coupled
together, the apparatus may be provided in a modular form, and thus
arranged to form a canopy structure of the required size, while
maintaining the size of the individual components of the apparatus
within manageable limits, both in terms of handling and
storage.
[0030] The interconnecting assembly may comprise an inter-engaging
mating structure. For example, the end of one sheet member may
comprise a female portion and the end of another sheet member may
comprise a corresponding male portion adapted to be received and
retained within said female portion. The male and female portions
may be integrally formed with the respective sheet members.
Alternatively, the male and female portions may be separately
formed and subsequently secured to the respective sheet
members.
[0031] In a preferred embodiment of the present invention, the
interconnecting assembly comprises an interconnecting member
adapted to be interposed between two sheet members and to provide a
coupling therebetween. Preferably, the interconnecting member is
adapted to be releasably coupled between two sheet members.
[0032] Preferably, the interconnecting member is rigid.
Advantageously, the interconnecting member may be elongate and is
preferably of a length substantially equal to the width of the end
portion of at least one of the sheet members to which said
interconnecting member is to be coupled. Preferably, the
interconnecting member is of a length substantially equal to the
width of the widest of the sheet members. This arrangement
advantageously provides support to the sheet members across the
entire width thereof, assisting to ensure creation of uniform
tension across the sheet members when secured between first and
second anchor means, and substantially minimising or eliminating
turbulence induced waves across the sheet members when exposed to
high winds. Alternatively, the interconnecting member may be of any
suitable length to be secured to an end portion of the sheet
member.
[0033] The interconnecting member may be adapted to be coupled to
the sheet members by, for example, bolting, riveting, clamping,
adhesive bonding or the like, or any suitable combination thereof.
Alternatively, and in a preferred embodiment, the interconnecting
member and sheet members define inter-engaging profiles adapted to
be mated together and engaged to couple the sheet members to the
interconnecting assembly. In one embodiment of the present
invention, one of the interconnecting member and sheet members
defines a female portion, and the other of the interconnecting
member and sheet members defines a corresponding male portion. The
female portion may comprise a channel, whereas the male portion may
comprise a suitably profiled element adapted to be received within
said channel. Preferably, the interconnecting member defines two
female portions adapted to respectively receive a male portion
provided on each of the sheet members.
[0034] Alternatively, the interconnecting member may be coupled to
the sheet member via a dove-tail arrangement, or equivalent mating
structure or the like.
[0035] The interconnecting member may be of a metal or metal-alloy
material, such as an aluminium alloy, steel or the like.
Alternatively, the interconnecting member may be formed of a
polymeric material, composite material or the like. In one
embodiment of the present invention, the interconnecting member may
be formed by extrusion. Alternatively, the interconnecting member
may be cast. Alternatively, or additionally, the interconnecting
member may be machined.
[0036] In embodiments of the present invention, a plurality of
interconnecting members may be provided and adapted to be
interposed between two sheet members.
[0037] Advantageously, the sheet members may be adapted to be
secured side-by-side.
[0038] Preferably, the sheet member is non-perforated. Preferably
also, the sheet member is flexible which advantageously permits,
among other things, the sheet member to be secured over assets of
varying shapes and to be folded for storage or transportation or
the like. Preferably, the sheet member comprises a fabric material,
such as a woven fabric, non-woven fabric, laminated fabric,
composite fabric or the like. The sheet member may comprise any
suitable material, such as polyester, Kevlar.RTM., Nylon,
Mylar.RTM., or the like.
[0039] Advantageously, the sheet member may be square or
rectangular or the like. Alternatively, at least a portion of the
sheet member may comprise tapered edges. In a preferred embodiment
of the present invention, a plurality of sheet members are
provided, wherein at least one sheet member is square or
rectangular, and at least one sheet member is substantially
triangular in shape. In a preferred embodiment, a square or
rectangular form sheet member is coupled to the first connecting
assembly, and a substantially triangular shaped sheet member is
coupled to the second connecting member.
[0040] Preferably, the apparatus comprises a protrusion adapted to
extend outwardly relative to a surface of the sheet member.
Advantageously, the protrusion may be elongate and arranged to be
substantially perpendicular with a central axis of the sheet
member. Beneficially, the protrusion may be of a length
substantially equal to the width of the sheet member. Preferably,
in use, the protrusion is adapted to extend generally upwardly from
the apparatus and into an air flow, thus causing separation of the
air flow from a surface of the apparatus, assisting to reduce the
static air pressure of the air flow and thus the net lift force
which may act on the asset over which the apparatus is located. In
a preferred embodiment of the present invention, the protrusion is
adapted to be positioned adjacent the highest point of the asset
over which the apparatus is located, such that flow separation will
advantageously be achieved at the downstream side of the asset when
exposed to an air flow, for example.
[0041] Preferably, the protrusion is adapted to be releasably
coupled to the apparatus. The protrusion may be coupled to the
sheet member, for example to an end portion of the sheet member or
to a surface region of the sheet member. Alternatively, the
protrusion is preferably coupled to an interconnecting member
located between two sheet members. The protrusion may be coupled to
an interconnecting member via an inter-engaging profile arrangement
or the like. In an alternative arrangement the protrusion may be
otherwise fixed to an interconnecting member, for example by
clamping, bolting, screwing, riveting, gluing, welding or the like.
In one embodiment the protrusion is mounted on or integrally formed
with a first support member and positioned on one side of an
interconnecting member, wherein the first support member is engaged
by a second support member located on an opposite side of said
interconnecting member. In this arrangement the protrusion and
first support member are clamped against the interconnecting
member. The first and second support members may be engaged via a
releasable connection, such as a snap-fit connection, bolting,
screwing or the like. In one embodiment one of the first and second
support members comprises at least one engaging member adapted to
extend towards and engage the other of the first and second support
members. The at least one engaging member may extend through an
interconnecting member, or alternatively, or additionally, may
extend around a side edge of an interconnecting member.
[0042] The protrusion may be of a metal or metal-alloy material,
such as an aluminium alloy, steel or the like. Alternatively, the
protrusion may be formed of a polymeric material, composite
material or the like. In one embodiment of the present invention,
the protrusion may be formed by extrusion. Alternatively, the
protrusion may be cast. Alternatively, or additionally, the
protrusion may be machined.
[0043] In one embodiment of the present invention, the sheet member
is adapted to be coupled between first and second anchor means
positioned remote from the asset over which the sheet member is to
be located. Alternatively, the sheet member is adapted to be
coupled between first and second anchor means secured to the asset.
Alternatively further, the sheet member may be adapted to be
coupled to a first anchor means positioned remote from the asset,
and a second anchor means secured to the asset.
[0044] Preferably, the apparatus of the present invention further
comprises first and second anchor means between which the sheet
member may be secured. Preferably, the anchor means comprise a
coupling component, such as a lug, hook, loop, eyelet, threaded
portion or the like, adapted to be coupled to the sheet member,
either directly or via a connecting assembly.
[0045] In a preferred embodiment of the present invention, the
anchor means are adapted to be secured to the ground surrounding
the asset over which the sheet member is to be located. The anchor
means may be bolted to the ground, for example via a concrete pile
or the like. Alternatively, the anchor means may be adapted to be
driven into the ground to be supported subterraneously. For
example, the anchor means may comprise a spike or stake adapted to
be driven into the ground, and optionally secured therein, for
example via a concrete base or the like. Alternatively, the anchor
means may comprise an auger style earth anchor adapted to be driven
into the ground by boring. Alternatively further, the anchor means
may comprise a toggle style earth anchor adapted to be driven into
the ground and subsequently set in place by applying an axial
pulling force on said anchor. A toggle style anchor such as a
Duckbill.RTM. earth anchor may advantageously be utilised,
providing sufficient support while utilising minimal ground surface
area. Accordingly, the anchor means may be initially installed and
left in place such that the sheet member may be readily deployed at
short notice when required.
[0046] In one embodiment the anchor means comprises a toggle style
earth anchor having a toggle element pivotally coupled to one end
of an elongate member. Advantageously, a central region of the
toggle element is pivotally coupled to the elongate member.
Preferably, the toggle element is adapted to be pivoted between a
first position in which the toggle element is aligned substantially
parallel with a longitudinal axis of the elongate member, and a
second position in which the toggle element is aligned transversely
of the longitudinal axis of the elongate member.
[0047] Preferably, the anchor further comprises an adjustable
member adjustably mounted on the elongate member and aligned
substantially coaxially therewith such that a telescoping effect
between the elongate member and adjustable member may be achieved.
Accordingly, the length of the anchor may be varied. In a preferred
arrangement the adjustable member is threadably coupled to the
elongate member such that relative rotation of the adjustable
member and elongate member permits adjustment therebetween.
[0048] Advantageously, in use, the toggle element of the anchor may
be located in the first position and the anchor subsequently driven
into the ground, for example by hammering or the like, with an end
of the toggle element leading. A driving rod may be utilised during
insertion of the anchor into the ground. For example, the driving
rod may engage the toggle element and be adapted to apply or
transmit a driving force thereto to drive the anchor into the
ground. Once this initial insertion is completed, the driving rod
may be removed, or alternatively retained in place. Following this
initial step of insertion, the entire anchor may be pulled in a
reverse or extraction direction, for example by pulling on the
adjustable member, thus causing the toggle element to pivot
relative to the elongate member towards the second position. In
this position the toggle element provides resistance to further
extraction thus establishing a suitable anchor. Once the toggle
element is positioned as described above, the adjustable member may
be adjusted relative to the elongate member to alter the length of
the anchor. The adjustable member may be translated so as to
protrude from the ground by a desired extent. However, in a
preferred embodiment the adjustable member is translated such that
an upper end thereof is located adjacent, or below the ground. In
this way, an anchor may be established with minimal or no protusion
above ground level.
[0049] Preferably, the anchor further comprises a coupling
arrangement adapted to be coupled to the sheet member, either
directly or via a connecting assembly. The coupling arrangement is
preferably positioned adjacent an end of the adjustable member,
preferably an upper end when in situ. The coupling arrangement may
be integrally formed with the adjustable member. Alternatively, the
coupling arrangement may be secured to or engaged with the
adjustable member. The coupling arrangement may comprise a ground
engaging member, such as a socket or the like, and a coupling
component, such as an eye plate adapted to be retained by the
ground engaging member. Preferably, the ground engaging member is
secured in place by the adjustable member. Advantageously, the
ground engaging member comprises a socket adapted to be at least
partially embedded in the ground.
[0050] Preferably, the apparatus is adapted for use in protecting a
permanent building from damage during high wind conditions.
Advantageously, the apparatus is adapted for protecting mobile
structures, such as vehicles, mobile homes, trailers, boats ashore,
aircraft or the like.
[0051] Preferably, a plurality of individual apparatuses of the
present invention are adapted for use in combination to provide a
system for protecting an asset. Advantageously, the provision of a
plurality of apparatuses provides multiple redundancies such that
failure of one apparatus will not be sufficient to compromise the
integrity and effectiveness of the entire system.
[0052] According to a second aspect of the present invention, there
is provided a method for protecting an asset. The method includes
positioning a sheet member over an upper surface of an asset,
securing one end of the sheet member to a first anchoring means via
a first connecting assembly, and securing an opposite end of the
sheet member to a second anchoring means.
[0053] Preferably, the method further comprises the step of
coupling together a plurality of sheet members to form a canopy
structure, and securing said canopy structure between said first
and second anchoring means. Advantageously, the sheet members may
be coupled together either directly, or alternatively via an
interconnecting member.
[0054] Advantageously, the method may further comprise the step of
setting in place said first and second anchoring means. The first
and second anchoring means may be positioned remotely from the
asset, for example in the ground surrounding the asset.
Alternatively, the anchoring means may be positioned on the
asset.
[0055] Preferably, the first connecting assembly comprises at least
one anchor engaging member adapted to be secured at one end to the
sheet member, and at an opposite end to the first anchoring means.
Preferably, the anchor engaging member comprises a flexible
elongate element, such as a rope, cable, webbing or the like.
Alternatively, the anchor engaging member may comprise a
substantially rigid element, such as a rod or bar or the like, of
any suitable material, such as metal or the like.
[0056] The anchor engaging member may be directly secured to the
sheet member, for example via an eyelet, lug, bracket or the like
in or on the sheet member.
[0057] Preferably, the first connecting assembly further comprises
at least one connecting member adapted to be coupled to an end
portion of the sheet member, wherein the anchor engaging member is
adapted to be secured to the sheet member via said connecting
member. The anchor engaging member may be secured to the connecting
member via an eyelet, lug, bracket, threaded coupling or the like.
Alternatively, the anchor engaging member may be secured to the
connecting member via an inter-engaging mating profile defined
between the anchor engaging member and sheet member.
[0058] Preferably, the sheet member is coupled to the second
anchoring means via a second connecting assembly.
[0059] According to a third aspect of the present invention, there
is provided a system for use in protecting an asset. The system
includes a plurality of sheet members adapted to be located over an
upper surface of an asset and secured respectively between first
and second anchoring means and a plurality of connecting assemblies
adapted to be coupled between a respective sheet member and a
respective first anchoring means.
[0060] According to a fourth aspect of the present invention, there
is provided a kit of parts for forming an apparatus for use in
protecting an asset. The kit of parts includes at least one sheet
member, and a first connecting assembly, wherein the sheet member
is adapted to be located over an upper surface of an asset and
secured between first and second anchoring means, the first
connecting assembly being adapted to be coupled between one of the
first and second anchoring means and the sheet member.
[0061] Preferably, the kit of parts comprises a second connecting
assembly adapted to be coupled between the other of the first and
second anchoring means and the sheet member.
[0062] Preferably also, the kit of parts comprises a plurality of
sheet members adapted to be secured together. Advantageously, the
kit of parts may further comprise at least one interconnecting
assembly adapted to be coupled between adjacent sheet members, when
in use.
[0063] According to a fifth aspect of the present invention, there
is provided a connection assembly that includes an elongate first
member having an asymmetrical lateral cross-sectional profile and
defining a notch in an outer surface thereof and a second member
comprising an eyelet adapted to receive the first member when the
first and second members are relatively positioned in a first
orientation, wherein rotation of the eyelet relative to the first
member engages a portion of the eyelet within the notch of the
first member.
[0064] Accordingly, by locating a portion of the eyelet within the
notch in the first member, relative lateral motion of the eyelet,
and second member, along the first member may be prevented.
[0065] According to a sixth aspect of the present invention, there
is provided an anchor that includes an elongate member, a toggle
element pivotally coupled to one end of the elongate member,
wherein the toggle element is adapted to be pivoted between a first
position in which the toggle element is aligned substantially
parallel with a longitudinal axis of the elongate member, and a
second position in which the toggle element is aligned transversely
of the longitudinal axis of the elongate member, and an adjustable
member adjustably mounted on the elongate member and aligned
substantially coaxially therewith.
[0066] In a preferred arrangement the adjustable member is
threadably coupled to the elongate member such that relative
rotation of the adjustable member and elongate member permits
adjustment therebetween.
[0067] Advantageously, in use, the toggle element of the anchor may
be located in the first position and the anchor subsequently driven
into the ground, for example. Following this initial step of
insertion, the entire anchor may be pulled in a reverse or
extraction direction, for example by pulling on the adjustable
member, thus causing the toggle element to pivot relative to the
elongate member towards the second position. In this position the
toggle element provides resistance to further extraction thus
establishing a suitable anchor. Once the toggle element is
positioned as described above, the adjustable member may be
adjusted relative to the elongate member to alter the length of the
anchor. The adjustable member may be translated so as to protrude
from the ground by a desired extent. However, in a preferred
embodiment the adjustable member is translated such that an upper
end thereof is located adjacent, or below the ground. In this way,
an anchor may be established with minimal or no protrusion above
ground level.
[0068] Preferably, the anchor further comprises a coupling
arrangement. The coupling arrangement is preferably positioned
adjacent an end of the adjustable member, preferably an upper end
when in situ. The coupling arrangement may be integrally formed
with the adjustable member. Alternatively, the coupling arrangement

coupling arrangement may comprise a ground engaging member, such as
a socket or the like, and a coupling component, such as an eye
plate adapted to be retained by the ground engaging member.
Preferably, the ground engaging member is secured in place by the
adjustable member. Advantageously, the ground engaging member
comprises a socket adapted to be at least partially embedded in the
ground.

DETAILED DESCRIPTION OF THE DRAWINGS
[0086] Reference is first made to FIG. 1 in which there is shown a
plan view of an apparatus, generally identified by reference
numeral 10, in accordance with an embodiment of the present
invention. As will be discussed in more detail below, the apparatus
10 is adapted for use in providing protection to an asset, such as
a building or the like from damage which may be caused during high
wind conditions.
[0087] The apparatus 10 comprises a first flexible sheet member 12
which is generally rectangular in shape, and a second flexible
sheet member 14 which is generally triangular in shape, wherein the
first and second sheet members 12, 14 are coupled together via a
rigid interconnecting member 16. Preferred forms of interconnecting
member 16 will be discussed in detail below. The first and second
sheet members 12, 14 are composed primarily of a fabric material,
such as a woven fabric, non-woven fabric, laminated fabric,
composite fabric or the like, and may comprise materials such as
polyester, Kevlar.RTM., nylon, Mylar.RTM. or the like.
[0088] One end of the first sheet member 12 is, in use, coupled to
a first anchor (not shown) via a first connecting assembly,
generally identified by a reference numeral 18. The connecting
assembly 18 comprises a rigid connecting member 20 coupled to one
end of sheet member 12, and a pair of anchoring cables 22, 24 fixed
at one end to the connecting member 20 and at an opposite end to a
suitable anchor or anchors (not shown). The first connecting
assembly 18 is particularly advantageous in that sheet member 12
will be supported across its entire width, assisting to ensure
creation of uniform tension across sheet member 12, and assisting
to substantially minimise or eliminate turbulence induced waves
which may propagate across sheet member 12 when exposed to high
winds.
[0089] The triangular shaped second member 14 is secured to a
further anchor (not shown) via a single anchoring cable 26, which
is fixed to sheet member 14 via an eyelet portion 28. Thus, in use,
the apparatus 10 may be located over an upper surface of an asset
such as a building, boat ashore, plane or the like, and anchored in
place via the three anchoring cables 22, 24, 26, and three
respective anchoring points. This arrangement is particularly
advantageous in that a substantially uniform tension will be
achieved in the apparatus 10, and turbulence induced fluttering of
the sheet members 12, 14 will be minimised, while assisting to
prevent twisting of the apparatus 10.
[0090] Reference is now made to FIG. 2 of the drawings in which
there is shown a cross-sectional view taken along line 2-2 of FIG.
1, of the connecting member 20, demonstrating the manner in which
member 20 is coupled to the end of sheet member 12.
[0091] Connecting member 20 defines a longitudinal bore 30, which
is open at one side via longitudinal slot 32, thus forming a
substantially C-shaped channel 34. Sheet member 12 defines a
profiled end portion, generally identified by reference numeral 36,
which is adapted to be received within said C-shaped channel 34 of
member 20. The profiled end portion 36 is formed by a cylindrical
member 38, which may be a rigid bar, flexible rope, cord, wire or
the like, over which member 38 the material of sheet member 12 is
looped. As shown, the maximum outer diameter of the cylindrical
member 38 is greater than the width of the longitudinal slot 32,
such that the profiled end portion 36 of sheet member 12 will not
inadvertently pass through slot 32, thus causing the sheet member
12 to become detached from the connecting assembly 18. In use, the
profiled end portion 36 of sheet member 12 is slidably received
within the channel 34 from one end of the connecting member 20.
[0092] The connecting member defines an aerodynamically profiled
leading edge which assists to minimise drag induced forces applied
thereto when exposed to high wind conditions, and assisting to
limit turbulent flow across the sheet member 12 which may otherwise
cause flow induced fluttering or vibration to propagate across said
sheet member 12, resulting in increased cyclic loading on the
connecting assembly 18 and anchor (not shown) which may lead to
premature material fatigue.
[0093] Reference is now made to FIGS. 3A and 3B which demonstrate
the method by which anchoring cables 22, 24 are connected to the
connecting member. Each cable (only cable 24 is shown in FIGS. 3A
and 3B) terminates in a strop 100 formed by looping the end of the
cable 24 around an eyelet 102 and securing using a crimp fitting
104. The eyelet 102 is of a profile corresponding to that of the
connecting member 20 such that the eyelet 102 may be passed over
the connecting member 20 only when in the relative position shown
in FIG. 3A. The connecting member 20 defines a notch 106 in an
outer surface thereof and extending into the C-shaped channel 34.
The eyelet 102 may therefore be slid over the connecting member 20
until aligned with the notch 106, and then rotated in the direction
of arrow 108 (FIG. 3B) such that a portion of the eyelet 102 is
received within the notch 106. In this position the eyelet 102, and
thus cable, become reliably secured to the connecting member 20.
Furthermore, once located within the notch 106, the eyelet 102 will
prevent the sheet member 12 from sliding from the C-shaped channel
34.
[0094] An end cap 109 for use with the connecting member 20 is
shown in FIG. 4, reference to which is now made. The cap 109
includes a socket 110 adapted to be fitted on the end of connecting
member 20, and a spherical hollow member 112 mounted on the socket
110. The cap 109 may be used to provide end-protection to an
installed connecting member 20 and prevent injury to a person
passing the member 20.
[0095] Reference is now made to FIG. 5 of the drawings in which
there is shown a cross-sectional view of one form of an
inter-connecting member, designated 16a, which may be interposed
between sheet members 12 and 14. In a similar fashion to the
connecting member 20 shown in FIG. 2, inter-connecting member 16a
comprises a first C-shaped channel 40 adapted to receive a profiled
end portion 42 of sheet member 12, and a second C-shaped channel 44
adapted to receive a corresponding profiled end portion 46 of sheet
member 14. Profiled end portions 42, 46 of the respective sheet
members 12, 14 are similar to end portion 36 in that each comprise
respective cylindrical members 48, 50 over which the sheet members
12,14 are looped.
[0096] An alternative form of interconnecting member for use in
coupling together the sheet members 12, 14 is shown in the
cross-sectional view of FIG. 6, wherein the interconnecting member
is identified by reference numeral 16b. Interconnecting member 16b
is similar to that member 16a shown in FIG. 5, in that it comprises
first and second C-shaped channels 51, 52 which receive respective
profiled end portions 54, 56 of sheet members 12, 14, the profiled
end portions 54, 56 being formed by looping the sheet member
material over respective cylindrical members 58, 60.
[0097] The interconnecting member 16b further defines an elongate
slotted channel 62 within which is located an inverted T-shaped bar
64. In use, bar 64 is adapted to extend generally upwardly from the
apparatus 10 and into an air flow, thus causing separation of the
air flow from the upper surface of the apparatus 10, assisting to
reduce the static air pressure of the air flow and thus reduce the
net lift force which may act on the asset over which the apparatus
10 is located.
[0098] A further alternative form of interconnecting member is
shown in FIG. 7, wherein the interconnecting member is identified
by reference numeral 16c. It should be noted that member 16c is
substantially identical to member 16b shown in FIG. 6, and as such
like components share the same reference numerals. Interconnecting
member 16c differs from member 16b shown in FIG. 6 in that member
16c defines a second elongate slotted channel 62a within which is
located a second T-shaped bar 64a. Accordingly, interconnecting
member 16c is substantially symmetrical. Thus, the interconnecting
member 16c may advantageously be utilised in either orientation,
and, furthermore, the lowermost T-shaped bar 64a may conveniently
act as a stand-off, providing a spacer between the member 16c and,
for example, the roof portion of a building.
[0099] A still further alternative form of interconnecting member
is shown in FIGS. 8A and 8B, wherein the interconnecting member is
generally identified by reference numeral 16d. Referring initially
to FIG. 8A, member 16d comprises two opposed C-shaped channel
portions 114, 116 integrally formed with and connected via a
elongate web portion 118. In a similar manner to that discussed
above, the ends of adjacent sheet members are slid into respective
channel portion 114, 116. The web portion 118 defines a plurality
of apertures 120 (only one shown) along the length thereof, the
function of which will now be described with reference to FIG. 8B,
which is a cross-sectional view of member 16d taken along line B-B
in FIG. 8A. Mounted on an upper surface of the member 16d is an
upper support member 122 which comprises an upwardly extending
projection 124, which in use functions to cause separation of air
flow from the upper surface of the apparatus 10 when in use.
Support member 122 further comprises a plurality of downwardly
extending cylindrical members 126 (only one shown) distributed
along the length thereof and in use adapted to extend through
respective apertures 120 in the interconnecting member 16d. The
free end of each cylindrical member 126 incorporates a barbed
flange 128 which engages a lower support member 130 located on a
lower surface of member 16d. The lower support member 130 defines a
plurality of apertures 132 (only one shown) for receiving
respective flanges 128. Accordingly, in use, the interconnecting
member 16d is clamped between the upper and lower support members.
This arrangement provides protection to member 16d, and in use
provides protection to the asset over which the apparatus 10 is to
be located.
[0100] A perspective view of the interconnecting member 16d and
upper and lower members 122, 130, in use, is shown in FIG. 9,
reference to which is now made. Located at either end of the
assembly are upwardly extending ears 134 which act to guide the
apparatus over and around an asset, such as a building. The ears
are integrally formed with the upper support member 122 and are
connected to the projection 124 which provide rigid structural
support to the ears 134.
[0101] Reference is now made to FIG. 10 of the drawings in which
there is shown a diagrammatic representation of a building 66 over
which is located and secured a plurality of apparatuses 10 in order
to protect said building 66 from damage which may be caused by wind
induced loading. Each apparatus 10 is secured between anchors 68
located on either side of the building 66, and in the preferred
embodiment shown, the anchors 68 are positioned remotely from the
base 70 of the building 66. Accordingly, the apparatuses 10
collectively define a canopy which extends from one side of the
building 66 to the other. The canopy formed by the individual
apparatuses 10 advantageously deflects wind over the building 66,
thus reducing the wind induced forces imparted thereupon.
Additionally, the apparatuses 10 assist to minimise any pressure
differential externally and internally of the building 66, which
may otherwise cause significant damage to the roof portion 72 of
the building 66. Furthermore, the combined effect of the
apparatuses 10, by being secured between anchors 68 on either side
of the building 66, will assist to retain the building at its
intended location, and provide an increased retaining force to
parts of the building 66, such as the roof portion 72.
Advantageously, the provision of a plurality of apparatuses 10
provides multiple redundancies such that failure of one apparatus
10 will not be sufficient to compromise the integrity and
effectiveness of the entire protection system.
[0102] An end view of the building 66 is shown in FIG. 11, wherein
a single apparatus 10 is shown located over the roof portion 72 of
the building 66, and anchored between anchor points 68. As noted
above with reference to FIG. 10, the anchor points 68 are distanced
from the base portion 70 of the building 66 which advantageously
provides improved streamlining of the building 66, thus reducing
the drag forces and dynamic pressure forces imparted thereon when
exposed to high wind conditions.
[0103] It should be understood that many forms of anchor 68 may be
utilised. However, in the preferred embodiment shown, each anchor
68 incorporates a respective toggle style anchor member 74 which
comprises an elongate drive member 76 having a lug 78 at one end
extending above the ground level 80, and a toggle portion 82
located at the opposite end and adapted to be located below ground
level 80. The anchor members 74 are located in place by being
driven into the ground, and subsequently secured therein by
applying a pulling force on the anchor member 74 to position the
toggle portion 82 in the position as shown in FIG. 11. Accordingly,
the system permits the anchors to be installed and retained in
place to be used as required. In this way, once the system has been
installed, the components and anchorages may be individually and
regularly tested in order to quality assure the system. A detailed
description of a preferred form of ground anchor is provided below
with reference to FIGS. 12 to 15.
[0104] Referring still to FIG. 11, it should be noted that the
apparatus 10 further comprises a tensioning system 84 which is
adapted to apply tension to the apparatus 10 between the anchor
points 68. In the embodiment shown in FIG. 11, the tensioning
system is secured to anchoring cable 26. However, it should be
understood that a tensioning system may be provided on any or all
of the three anchoring cables 22, 24, 26 (FIG. 1) of the apparatus
10. One or more of the anchoring cables may comprise or be used in
conjunction with a cam-cleat or similar fitting (not shown) which
permits adjustment of the cable(s) and subsequently locks the
cable(s) at the desired length.
[0105] In the embodiment shown in FIG. 11, the T-shaped bar 64 or
projection 124 mounted on an interconnecting member is shown
positioned at the highest point 86 of the roof portion 72. This
arrangement advantageously causes separation of the airflow to be
achieved at the downstream side of the building 66, thus maximising
the reduction in the lift force which may be applied to roof
portion 72.
[0106] A preferred form of ground anchor will now be described with
reference to FIGS. 12 to 15. Referring initially to FIG. 12, the
ground anchor, generally identified by reference numeral 136,
comprises a toggle 138 pivotally mounted on a lower end of an
elongate rod 140. An adjustable member 142 is threadably coupled to
rod 140 via threaded connection 144. In use the toggle 138 is
initially position to be aligned parallel with rod 140, as shown in
FIG. 12, and the anchor 136 then driven into the ground 146. To
assist insertion a drive rod 148 (only partially shown) is inserted
into a slot 150 in the toggle 138 and then utilised to drive the
anchor into the ground 146, for example by hammering. Once driven
in to a sufficient depth the drive rod 148 is removed and the
entire anchor 136 is pulled via the adjustable member 142 in an
extraction direction, as shown in FIG. 13. Upon pulling, the toggle
138 is caused to pivot to a position substantially perpendicular to
rod 140 at which point the toggle 138 provides resistance to
further extraction thus establishing a suitable anchor.
[0107] Once the toggle 138 is positioned as described above, the
adjustable member 142, which projects above the ground level 146,
is adjusted relative to rod 140 to alter the length of the anchor
136. The adjustable member 142 is translated such that an upper end
thereof is located slightly below the ground level 146, as shown in
FIG. 14. In this way, an anchor may be established with minimal or
no protrusion above ground level. The upper end of the adjustable
member 142 comprises a circumferential flange 160 which engages and
retains in place a ground socket 162, which will now be described
in detail with reference to FIG. 6, which is an exploded
perspective view of the socket 162 and associated components.
[0108] The socket 162, which is shown partially cut-away for
clarity, comprises a cup 164 and an annular flange 166 coupled to
the open end of the cup 164. The flange 166 is adapted to be
positioned substantially flush with ground level when in use.
Located around the outer perimeter of the cup 164 are four ribs 168
spaced 90.degree. from each other, wherein the ribs 168 assist to
prevent or at least minimise movement of the socket 162 when
located in the ground.
[0109] A slot 170 extends through the wall of the cup 164 and is
adapted to receive the end of the adjustable member 142. The slot
terminates in an enlarged aperture 172 which permits the
circumferential flange 160 of the adjustable member 142 to pass
therethrough and subsequently be retained by the slot 170.
Accordingly, during installation of the anchor 136 (FIGS. 12 to
14), the socket 162 may be engaged with the adjustable member 142
via the slot 170 and aperture 172, and then subsequently drawn into
the ground by tightening the adjustable member against the inner
surface of the cup 164.
[0110] Referring still to FIG. 15, an eye-plate 174 is provided and
inserted into the cup 164 of the socket 162, wherein the eye-plate
174 comprises a lug 176 which provides an attachment point. Once
the eye-plate 174 is located within the cup 164 a retaining ring
178 is positioned within a recessed lip 180 formed on the flange
166 and secured thereto via screws (not shown). The retaining ring
170 therefore retains the eye-plate 174 within the cup 164. A cap
182 is provided to cover the cup opening when the anchor is not in
use. When the anchor is required, the cap 182 may be removed to
access the eye-plate 174, and an anchor cable or the like then
coupled to the lug 176.
[0111] Reference is now made to FIG. 16 in which there is shown a
portion of the apparatus 10 which incorporates a solar cell 184 for
generating an electrical current. In the embodiment shown the
generated current may power an electronic instrument, such as a
tension indicator having a digital display 186 for displaying the
applied tension across the apparatus.
[0112] To assist in transporting and deploying the apparatus 10, a
cart, shown diagrammatically in FIG. 17 and identified by reference
numeral 188, may be utilised. The cart 188 comprises a trough 190
and opposed channel sections 192 which receive the ends of a
connecting member 20 about which the apparatus 10 is wound. The
apparatus 10 may therefore be wheeled to its desired location and
subsequently deployed directly by unrolling.
[0113] When not in use, the apparatus 10 may be stored in a storage
enclosure, such as that shown diagrammatically in FIG. 18. The
enclosure, identified by reference numeral 194 incorporates a
plurality of bays 196 to accommodate a number of apparatuses 10. A
compartment 198 may also be provided to accommodate the deployment
cart 188 shown in FIG. 17. Access to the bays 196 may be achieved
from both sides of the enclosure 194. The enclosure 194 may be
closed by roller shutters or other suitable door mechanism.
[0114] The apparatus 10 according to the present invention provides
a highly modular system which may be readily assembled and deployed
for use in protecting an asset such as a building. Accordingly, the
apparatus may be provided in individual components and subsequently
assembled to provide the required dimensions for use with the
specific asset to be protected. Furthermore, providing a highly
modular apparatus permits said apparatus to be readily stored when
not in use, and also permits the apparatus to be easily handled and
readily deployed with minimal effort and expenditure of time.
[0115] It should be understood that the embodiments described above
are merely exemplary and that various modifications may be made
thereto without departing from the scope of the invention. For
example, any number of sheet members 12, 14 may be utilised to form
the apparatus 10 of the present invention. Additionally, any number
of anchoring cables may be used to secure the apparatus between
suitable anchor points. Furthermore, the anchoring cable may
incorporate harmonic dampers to eliminate or at least reduce wind
induced vibration and harmonics. Additionally, the releasable
coupling between the sheet members and the connecting and
interconnecting members may be of any suitable interengaging
coupling arrangement, such as a dove-tail type arrangement or the
like. Additionally, embodiments of the invention may utilise
threaded connections between the sheet members and connecting and
interconnecting members. Additionally, it should be understood that
the apparatus 10 of the present invention may be utilised for use
in protecting any other asset which may be exposed to high wind
conditions, such as mobile homes, trailers, vehicles, or the
like.
