Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to anti-bird frame assemblies which
are attachable to the ledges of buildings for the purpose of
preventing birds from landing and nesting thereon.
[0003] 2. Prior Art
[0004] The problems of birds sitting or nesting on buildings has
been around for centuries. The upper ridges or ledges of a building
provide and ideal safe location for birds to enjoy. Birds, being
very gregarious will often roost on buildings in large numbers.
These birds may typically be pigeons, starlings, sparrows, or
finches. These birds leave behind bird guano (a.k.a. droppings).
These droppings deface the stone and metal of the building, because
of the acidity in that guano. This will cause permanent damage to
the substrata of a building.
[0005] Anti bird arrangements have also included nets which may be
arranged around the ledges or corners of the upper portions of
those buildings. Other arrangements for such anti-bird devices
include an array of spikes or posts of needle-like sharpness. Often
devices like this might injure the birds, impale them and such
devices require a high number of securement locations by which
those devices are attached to the building. Such devices are often
unsightly themselves. Also, by increasing the number of attachment
locations on a given building, such attachment mechanisms may be
dangerous to the buildings as well.
[0006] It is an object of the present invention, to provide a
humane anti-bird apparatus which overcomes the disadvantages of the
prior art.
[0007] It is a further object of the present invention to provide a
simple easy to install assembly for buildings which will prevent
the landing of birds thereon.
[0008] It is yet a further object of the present invention to
provide an arrangement for keeping birds from buildings which
arrangement is not readily viewable by anyone other than the
birds.
[0009] It is still yet a further object of the present invention to
provide an anti-bird system with a certain degree of resilience and
flexure which will not harm the birds yet will provide landing
discouragement to anyone of a variety of types of birds.
[0010] It is still yet a further object of the present invention
which minimizes its deleterious impact on the building to which it
is attached.
BRIEF SUMMARY OF THE INVENTION
[0011] The present invention relates to an anti-bird landing
assembly which is attachable to, for example, the ledge of a
structure such as for example, a building, a bridge or a monument,
so as to prevent birds from landing or roosting thereon. The bird
landing prevention assembly comprises a plurality of support
brackets which are to be attached in a spaced apart manner to the
upper surface of a ledge or the like of a building. Each support
bracket comprises a generally horizontally disposed based flange. A
unitary upright frame portion is arranged perpendicular to the base
flange. The upright frame portion of the support bracket comprises
an elongated middle arm which is in alignment with and is
perpendicular to the base flange. The upright frame of the support
bracket has an elongated first arm extending thereon having a
longitudinal axis which is arranged at about a 45 degree angle from
the longitudinal axis of the elongated middle arm. The upright
frame of the support bracket has a second arm arranged opposite
side of the middle arm from the first arm, and has a longitudinal
axis which is also arranged in an angle of about 45 degrees with
respect to the longitudinal axis of the middle arm.
[0012] The first arm has a distal end having a wire attachment node
spaced thereon. The middle arm has a distal end with a wire
attachment node thereon. The second arm has a distal end with a
wire attachment node thereon. The wire attachment node of the first
arm and the wire attachment node of the middle arm are spaced about
one half to one inch apart along the longitudinal (vertical) axis
of the middle arm. The same vertical spaced apart relationship
exists for the wire attachment node of the second arm and the wire
attachment node of the middle arm.
[0013] The wire attachment node of the first arm and the wire
attachment node of the middle arm have a horizontal separation of
about two and one half to three inches therebetween. The spaced
apart arrangement of the wire attachment nodes of each respective
arm is important so as to prevent entry by birds if those wire
attachment nodes were too far apart in as much as wires are strung
between corresponding arms of spaced apart support brackets
arranged on the ledge of a building. If the wires are too close
together, a pigeon for example, could sit on those wires or
straddle it. If they were too far apart, a bird could merely get
through the adjacent wires strung between adjacent support
brackets.
[0014] In one preferred embodiment of the present invention, the
respective wire attachment nodes are merely holes through which a
flexible filament or wire may be passed or attached. In the
attachment arrangement, a small coiled spring may be secured to the
attachment node to give its respective wire therewith a certain
uniform tension. Each respective elongated first arm, elongated
middle arm or elongated second arm are formed of thin material
which may have a certain slight flexibility to provide a certain
yielding to the wires when a bird strikes there against. The base
flange has several openings through which attachment means may be
secured to the building.
[0015] The securement openings are arranged in perpendicular
alignment to the plane of the support bracket so as to maximize the
ability of the support bracket to stay attached to the building
even after numerous "landings" by birds on the wire. If the
securement openings were arranged parallel to the plane of the
support bracket those openings would be more likely to cause damage
to the building by being too close to the edge of a ledge, and not
provide resistance to back and forth rocking of the frame assembly
and thus and come loose more easily.
[0016] The invention thus comprises an anti-bird assembly for the
prevention of landing of birds on the ledge of a building
comprising a plurality of spaced apart brackets. Each bracket
preferably comprises a base flange for attachment of the assembly
to a building, a frame portion connected to the base flange, and an
arrangement of arms connected to the frame portion, each of the
arms having a distal end with a wire attachment node thereon, and a
wire arranged between corresponding wire attachment nodes of
corresponding arms on adjacent spaced apart brackets.
[0017] The arms may include a first arm, a second arm and a middle
arm. The first arm, the middle arm and the second arm each have a
longitudinal axis, the first arm and the second arm are separated
by an angle of about 90 to about 120 degrees between one another.
The middle arm is spaced apart from both the first and second arms
by an angle of about 45 degrees to about 60 degrees. The
spaced-apart angle is preferably the same for both the first and
second arms with respect to the middle arm. The wire attachment
node of the middle arm is preferably spaced a vertical distance
away from the base flange of about 1/2 to 1 inch further apart from
the wire attachment node of the first arm. The wire attachment node
of the middle arm is preferably spaced a horizontal distance away
from the wire attachment node of the first arm by a distance of
about 2 and 1/2 inches to 3 inches. The base flange has at least
two spaced apart openings and preferably three therein for easier
securement of the bracket to spaced apart mortar joints or the
like, in any building ledge, at least two of the spaced apart
openings in the bracket being in perpendicular alignment with the
frame portion. The preferred triangular pattern of the openings in
the base flange prevents twisting of the bracket when the arms and
their connecting wires are tensioned and that pattern allows single
fix attachment when wires are attached immediately between adjacent
brackets. Fewer location points for the attachment process results
in fewer penetration points in the building's substrata. At least
one of the brackets preferably has an arm with a spring secured to
the wire connected to an arm thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0024] Referring now to the drawings in detail, and particularly to
FIG. 1, there is shown the present invention which comprises an
anti-bird landing assembly 10 which is attachable to, for example,
the ledge 12 of a structure such as for example, a building so as
to prevent birds from landing or roosting thereon. The bird landing
prevention assembly 10 comprises a plurality of support brackets
14, one bracket 14 being shown in FIG. 1, which are to be attached
in a spaced-apart manner to the upper surface of a ledge 12 or the
like of a building, as also represented in FIG. 4. Each support
bracket 14 comprises a generally horizontally disposed base flange
16. A unitary upright frame portion 18 is arranged perpendicular to
the base flange 16.
[0025] The upright frame portion 18 of the support bracket 14
comprises an elongated middle arm 20 which is in central alignment
with and is perpendicular to the base flange 16. The upright frame
portion 18 of the support bracket 14 also has an elongated first
arm 22 extending thereon having a longitudinal axis L1 which is
arranged at an angle "A" in a range of for example, about a 45
degree to a 60 degree angle from the longitudinal axis LM of the
elongated middle arm 20. The upright frame portion 18 of the
support bracket 14 has a second arm 24 arranged opposite side of
the middle arm 20 from the first arm 22, and has a longitudinal
axis L2 which is also arranged at an angle "B" in a range for
example, of about a 45 degree angle to about a 60 degree angle with
respect to the longitudinal axis LM of the middle arm 20. Angle "A"
and angle "B" preferably have the same number of degrees in one
preferred embodiment.
[0026] The first arm 22 has a distal end 26 having a wire
attachment node 28 spaced thereon. The middle arm 20 has a distal
end 30 with a wire attachment node 32 thereon. The second arm 24
has a distal end 34 with a wire attachment node 36 thereon. The
wire attachment node 28 of the first arm 22 and the wire attachment
node 32 of the middle arm 20 are spaced apart a distance "d" about
one half to one inches apart along the longitudinal axis LM of the
middle arm 20. The same vertically spaced-apart relationship exists
for the wire attachment node 36 of the second arm 24 and the wire
attachment node 32 of the middle arm 20. The wires may for example,
be attached or may merely pass through the respective "attachment"
nodes.
[0027] The wire attachment node 28 of the first arm 22 and the wire
attachment node 32 of the middle arm 20 have a horizontal
separation "h" of about two and one half to three inches
therebetween. The spaced-apart arrangement of the wire attachment
nodes 28, 32 and 36 of each respective arm 22, 29 and 24 is
important so as to prevent entry by birds if those wire attachment
nodes 28, 32 and 36 were too far apart in as much as wires 40 are
strung between corresponding arms of spaced-apart support brackets
14 arranged on the ledge 12 of a building, as represented in FIG.
4. If the wires are too close together, a pigeon for example, could
sit on those wires or straddle it. If they were too far apart, a
bird could merely get through the adjacent wires 40 strung between
adjacent support brackets 14.
[0028] In one preferred embodiment of the present invention, the
respective wire attachment nodes 28, 32 and 36 are merely holes
through which a flexible filament or wire 40 may be passed or
attached. In the attachment arrangement, a small coiled spring 42
may be secured to the attachment node 28, 32 and 36, as represented
in FIG. 4, to give its respective wire 40 therewith a certain
uniform tension. Each respective elongated first arm 22, elongated
middle arm 20 or elongated second arm 24 are formed of thin
material such as for example, thin stainless steel, which may have
a certain slight flexibility to provide a certain yielding to the
wires 40 when a bird strikes thereagainst. The base flange 16 has
several openings 48 through which an attachment means may be
secured to the building.
[0029] The securement openings 48 are arranged horizontally in
perpendicular alignment to the plane of the support bracket 14, in
base flange 16, as represented in FIG. 3 so as to maximize the
ability of the support bracket 14 to stay attached to the building
even after numerous "landing attempts" by birds on the wire. If the
securement openings 48 were arranged parallel to the plane of the
support bracket those openings would be more likely to cause damage
to the building by being too close to the edge of a ledge, and not
provide resistance to back and forth rocking of the frame assembly
and thus and come loose more easily. The holes 48, preferably three
in number, permit easier attachment to joints in the building.
Having to drill spaced apart holes in the building may damage the
building because of stress and fractures therein. The base flange
16 is shown with a triangular array of openings 48, as a further
preferred alternative spacing embodiment in FIG. 3A, to permit
greater attachment options in the securement of the bracket 14 to
the ledge of a building, particularly in mortar and/or cracks
between sections thereof.
[0030] The invention thus comprises a unique arrangement for
discouraging birds to land on a ledge of a building. The brackets
of the present invention are spaced apart far enough to minimize
the number of holes or securement means needed to be drilled or
otherwise secured to a side/ledge with the assembly 10 to a
building. The wires connecting adjacent brackets are spaced apart a
proper distance, both vertically and horizontally to prevent
straddling or nesting of any birds therein.
