Description

BIRD EXCLUSION APPARATUS
Technical Field of the Invention
The present invention relates to a bird exclusion apparatus Particularly, but not exclusively, for use on the underside of bridges.
Background to the Invention
Birds, in particular pigeons, are a significant problem in many buildings, for example railway stations, and beneath rail bridges. Birds can settle or form a habitat.
on the girders beneath rail bridges and girders forming part of the roof structure of a building, for example a railway station. Habitation of birds is not limited to upon girders but can occur upon any beam or similar structure. The birds may foul the railway station platforms, social areas and trains, as well as public footpaths and roads, creating unsightly areas for the public to use. Keeping the aforementioned areas clean of bird droppings is expensive, time-consuming and is problematic as many of these areas are deemed dangerous places to work and/or can only be cleaned at times outside of when trains are running, for example during the night.
It is also accepted that the areas where the birds may settle or form a habitat may require repair work or regular maintenance. As such, access to these areas is critical for repair and/or maintenance work.
Current methods of excluding birds from settling and forming a habitat in these areas include 'pigeon netting'. Pigeon netting comprises a net which is fixed below the girders, or similar structures, and prevents the birds from accessing the areas between the girders and the bridge, roof, etc. Pigeon netting acts as a barrier to prevent birds accessing girders on the underside of bridges or in roof structures of buildings.
However, a problem with pigeon netting is that. the netting often becomes unattached from its attachment position and hangs loosely which is unsightly and also dangerous if people are walking, or vehicles and machinery are being operated, below the loose hanging netting. In particular, pigeon netting which becomes loose on the underside of rail bridges presents a significant problem as the netting may become tangle with a passing train and subsequently with overhead power cables. If such a problem occurs, it may result in significant and expensive delays in the operation of the trains due to run along the train line beneath the bridge.
Moreover, pigeon netting does not allow easy access to the girders, or similar structures, below which the netting is attached. Often, if access to the girders is required, the netting is completely removed, maintenance and/or repair work carried out, and a new pigeon netting attached. This is expensive, time consuming and a waste of resources In view of the above, there is a need for an effective bird exclusion apparatus that prevents birds accessing areas such as the underside of a bridge or roof structure of a building, and which allows easy access for an operator to these areas if maintenance and/or repair work is required to be carried out.
Summary of the Invention
According to a first aspect of the present invention, there is provided an apparatus for excluding birds, the device comprising a first support bar and at least one panel, the first support bar comprising an attachment means permitting attachment of the first support bar to a flange, the first support bar comprising at least one first connection means permitting connection of the panel to the first support bar, wherein the panel is pivotable about the at least one first connection means such that the panel may be moved between an open position and a closed position.
It is to be understood that an 'open position' is one where an operator, and, therefore, also birds, have access to the areas above the panel when in use. It is to be understood that a 'closed position' is one where an operator, and, therefore, also birds, are prevented from accessing the areas above the panel when in use.
Advantageously, the panel of the apparatus may be used, when in a closed position, to prevent birds from accessing, settling or forming a habitat on girders beneath rail bridges and girders, or similar structures, forming part of the roof structure of a building, for example a railway station. Accordingly, the apparatus may be used to keep railway station platforms, social areas and trains, as well as public footpaths and roads, clear of bird droppings. Thus, preventing the need for expensive and time- 1 0 consuming work in clearing the aforementioned areas of bird droppings.
Beneficially, the panel is connected to the first support bar by an at least one first connection means, and is pivotable about the at least one first connection means. Thus, the panel may be moved from its closed position by rotating the panel about the at least one first connection means, therefore, displacing the panel away from its closed position and into an open position. Accordingly, when in the open position, this provides an operator access to the areas (for example, girder(s), roof structure, underside of a bridge etc.) which, when the panel is in a closed position, the operator cannot access. Beneficially, as the panel is pivotable about the connection means, the panel does not have to be completely removed from the support bar in order for the operator to gain access. This means that access to girder(s), roof structures, underside of a bridge etc, can be gained quickly and with ease, and without the need for any existing bird exclusion devices to be completely removed, which are often complicated and intricate procedures.
Beneficially, the attachment means provides a strong attachment of the apparatus to a flange, in particular, but not limited to, the flange of a girder or similar part of a roof structure. The attachment means, therefore, prevents the apparatus from being displaced from its position attached to the flange. Thus, the risk of the bird exclusion device become entangled with a passing train, or falling onto a rail station platform, or becoming a hazard for other similar reasons, is considerably reduced compared with existing bird exclusion devices, such as pigeon netting.
The first support bar may further comprise at least one second connection means permitting releasable connection of a panel to the firs( support bar. Thus, beneficially, the first support bar may comprise at least one first connection means permitting connection of a first panel to the first support bar, and an at least one second connection means permitting connection of a second panel to the first support bar.
The at least one first connection means may be a releasable connection means. Accordingly, the panel may be completely removed from its connection with the first support bar if, for example, an operator required additional space so that he can access the areas otherwise excluded by the panel when in a closed position.
The apparatus may further comprise a second support bar arranged adjacent to the first support bar such that the panel is supported by the second support. bar when in a closed position. Accordingly, the arrangement of the second support bar relative to the first support bar and flange defines an area which may be at least partially, preferably entirely, covered by the panel when in a closed position.
The second support bar may comprise at least one second connection means permitting releasable connection of the panel to the second support bar. Beneficially, when in the closed position, the panel may be connected to the second support bar, and the panel may be disconnected from the second connection means so that the panel may be moved to an open position.
The first support bar may be a T-bar. The second support bar may be a T-bar.
A T-bar typically comprises a planar lower leg and a planar upper leg perpendicular to the lower leg and intersecting with the lower leg at a midpoint thereof, forming a portion of the lower leg at either side of the upper leg. The lower surface of the lower leg faces downward when in use. Portions of the lower leg on either side of the upper leg each present a shoulder upon which a first connection means and/or a second connection means may be fixed. It is to be understood that a first connection means and/or a second connection means may be fixed to a first surface and/or a second surface of the upper leg of the T-bar. The T-bars are typically arranged in a grid pattern between adjacent flanges. The grid pattern may be formed of squares or rectangles (or other shapes).
The first support bar may comprise an at least one first connection means and an at least one second connection means.
The first support bar may be a T-bar comprising an at least one first connection means fixed to a shoulder portion of the T-bar, and an at least one second connection means fixed to an upper leg of the T-bar.

The anti-vibration tape may be positioned along an upper surface of a lower leg of a first T-bar or second T-bar. Beneficially, this arrangement prevents vibration of a panel against the first support bar and/or second support bar and, therefore, reduces noise. The anti-vibration tape may be in the form of a self-adhesive insulating foam tape.
The attachment means may be attached to the flange and/or the first support bar by compression and friction between the aforementioned elements. The attachment means may be attached the flange and/or the first support bar using non-penetrative means, such as an adhesive, or a penetrative means, such as a nut and bolt arrangement. Beneficially, when the attachment means is attached to the flange and/or the first support bar using non-penetrative means, the strength and integrity of the attachment means and flange and/or first support bar is maintained.
The attachment means may comprise a first engagement surface, for engagement of the attachment means to a flange, and a second engagement surface, for engagement of the attachment means to the first support bar.
At least a portion of the first engagement surface may be coated with an adhesive for attaching the attachment means to the flange. At least a portion of the second engagement surface may be coated with an adhesive for attaching the attachment means to the first support bar.

Referring to Figs. 1-3, there is shown an apparatus 1 for excluding birds. In the depicted example, the apparatus 1 is shown in use between two bridge girders 2a, 2b arranged parallel to each other. The apparatus 1 could equally be used between Orders forming part of a roof structure of a building or similar. Each girder 2a, 2b comprises a flange 11a, llb to which the apparatus 1 is attached when in use. Each flange 11a, llb comprises an upper surface llal, 11b1 and a lower surface 11a2, 1162. The apparatus 1 comprises a first support bar 3 in the form of a T-bar, a second support. bar 4 in the form of a T-bar, and a panel 5 arranged between the first support bar 3 and the second support bar 4. The first support bar 3 and the second support bar 4 are arranged perpendicular to the girders 2a, 2b to form a rectangular grid pattern. The first support bar 3, second support bar 4 and the panel 5 define an area through which a bird cannot pass through. As such, when in use, birds can be excluded from the area above the panel.
IS
The panel 5 is a mesh panel comprising a plurality of interlaced strands. The interlaced strands are arranged to form a square grid pattern. However, it will be apparent that other grid patterns may alternatively be used. It will also be apparent that the panel 5 may be in the form of any barrier that prevents birds passing through it. For example, the panel 5 may be a transparent Perspex@ screen or a plurality of parallel arranged bars connected at either end to a bar arranged perpendicular to the parallel bars.
With reference to Fig. 4, there is shown first support bar 3 attached to Order 2a via a first attachment means 6. The firs( attachment means is in the form of a Z-clip 6. The Z-clip 6 comprises a lower arm 7a and an upper arm 7b. The lower arm 7a comprises a first engagement surface 7a1, for engaging with girder 2a, and the upper arm 7b comprises a second engagement surface 7b1, for engaging with first support bar 3.
In the example shown, the first engagement surface 7a is coated with an adhesive (not shown) to adhere Z-clip 6 to girder 2a, and the upper arm 7b comprises a pair of penetrative fixing means 8 to fix the upper arm 7b to the first support bar 3. The first engagement surface 7a also comprises a sheet of insulated material (not shown) adhered to the first engagement surface 7a to prevent electrolytic activity between the Z-clip 6 and the girder 2a.
The first support bar 3, second support bar 4 and the strands of the mesh panel 5 are each made of galvanised steel. The interlaced strands of the mesh panel 5 arc arranged to form a square grid pattern.
The first support bar 3 is in the form of a T-bar but it will be appreciated that the first support bar 3 may be in the form of any bar or portion of material which can he arranged between a pair of girders and which can support a panel. In the example provided, and as shown in Fig. 7, the T-bar 3 comprises a planar upper leg 10a and a planar lower leg 10b. The planer upper leg 10a is arranged perpendicular to the lower leg 10b and intersecting with the lower leg 10b at a midpoint thereof, forming a portion of the lower leg 10b at either side of the upper leg 10a. The lower leg 10b comprises a lower surface 10c which faces downward when in use. The lower leg 10b comprises a first shoulder portion 10d and a second shoulder portion 10e; the two shoulder portions 10d, be being separated by the upper leg 10a. The upper leg 10a comprises a first surface 10f and a second surface 10g.
To the second shoulder portion 10e of the first support bar 3 are attached four first connection means 9 evenly spaced along the first support bar 3 (see Fig. 11). Each first connection means is in the form of an R-clip 9. Each R-clip 9 provides a pivotable and releasable attachment of the mesh panel 5 to the first support bar 3. As such, the panel 5 may be pivoted between a closed position, where the panel 5 is connected to the first connection means 9 and is in contact with the second support bar 4, therefore preventing birds from accessing the area above the panel, when in use, and an open position, where the panel 5 is pivoted about the first connection means 9, and while maintaining connection to the first support bar 3, allows access above the panel when in use to maintenance workers and/or birds.
Along the periphery of each shoulder portion 10d, 10e is a strip of anti-vibration tape 14 adhered to each respective shoulder portion 10d, 10e. The anti-vibration tape 14 is a self-adhesive insulating foam tape.
To the first surface 10f of the second support bar 4 are attached four second connection means 12 evenly spaced along the second support bar 4. In the present example, each second connection means is positioned opposite a corresponding first connection means 9 attached to an adjacent first support bar 3. However, it is to be understood that the second connection means 12 do not need to be positioned opposite a first connection means 9. Each second connection means 12 is in the form of an R-clip 12. Each R-clip provides a releasable connection of the mesh panel 5 to the second support bar 4. As such, when in the closed position, the panel 5 may he releasably locked into the second connection means 12 such that a degree of force is required to move the panel 5 from the closed position to the open position by releasing the panel 5 from the second connection means 12. Such force being achievable by a maintenance worker or similar, but not achievable by a bird flying into, or forcing itself against, the panel 5.
In the present example, each support bar 3, 4 may be considered a first support bar 3 in that it comprises at least one first connection means 9 and at least one second connection means 12. In the present example, the first support bar 3 comprises the first connection means 9, in the form of an R-clip, on the second shoulder portion 10c of the lower leg 10b, and further comprises the second connection means 12, in the form of an R-clip, on the first surface 10f of the upper leg 10a. Moreover, in the present example and as shown in Fig. 11, panel 5 is pivotably, and releasably, connected to a first support bar 3 via four first connection means 9, and releasably connected to a second support bar 4, which is a different support bar to the first support bar 3, via four releasable second connection means 12.
As shown in Fig. 10, the first support bar 3 and/or second support bar 4 may comprise a cable support 13. In the present example, the cable support 13 is in the form of a nut 13 adhered to the second shoulder portion 10e of the lower leg 10b. The cable support 13 allows a cable to be threaded through the apparatus. The cable may be an electrical cable.
The one or more embodiments are described above by way of example only.
Many variations are possible without departing from the scope of protection afforded by the appended claims.
