Abstract
A bird anti-perching device is described having a rotatable cylindrical member extending between two support members and capable of rotating freely if a bird lands thereon, thereby to form an unstable perch. The device can be attached to the ledge of a balcony in a number of ways to prevent birds from alighting on the balcony.
Description
- 2 -BIRD ANTI-PERCHING DEVICE
FIELD OF THE INVENTION
This invention relates to bird anti-perching devices.
More particularly this invention relates to a bird anti-perching device for discouraging birds from perching on a ledge or other surface.
OF THE INVENTION
Home owners and apartment dwellers often have difficulty with unwanted birds which alight on surfaces such as ledges, railings or fences and leave excrement when they leave.
It is possible to continually clean the affected surface but this does not address the cause of the problem, namely unwanted birds.
One attempt to solve the problem can be found in U.S. Patent No. 5,755,179 which utilizes a rectangular flat plate suspended by a rod. The flat plate can rotate and may throw the bird off the plate and prevent it from landing. The plate is positioned so that it rotates eccentrically around its axis.
Problems with this approach have become apparent because birds can perch on a flat plate if they have a second surface on which to balance a foot.
It would be advantageous to provide an anti-perching device which prevents a bird from getting a second foothold.
SUMMARY OF THE INVENTION
It is an object of the present invention to prevent a bird from perching on a ledge or other surface.

SUMMARY OF THE INVENTION
It is an object of the present invention to prevent a bird from perching on a ledge or other surface.
- 3 -Another object of the invention is to provide for an product which can be easily attached to the ledge or other surf ace .
Accordingly, there is provided a bird anti-perching device for discouraging birds from perching on a surface, comprising two spaced-apart support members; and a rotatable cylindrical member extending between said two support members and capable of rotating freely if a bird lands thereon, thereby to form an unstable perch.
According to one embodiment of the invention the support members each have a pin which is respectively inserted in the center of one end of the cylindrical member, and another portion which essentially clamps the cylindrical member parallel to the ledge such that it can rotate freely.
The cylindrical member is positioned so that there is not sufficient room for a bird to perch between the cylindrical member and the railing.
It will be understood that the cylindrical member could be of hollow, solid or other construction.
The cylindrical member could be made of a wide variety of materials. For example, the member could be made of wood, plastic, metal or some other material.
The support members could have a second pin immediately opposite the first pin so that a series of cylindrical members could be positioned along a railing.
In some cases it is not possible to use proper clamps to affix the cylindrical member to the ledge, and some form of velcro* clamping might be used.
It is also possible to permanently affix the cylindrical member to the ledge instead of using clamps.

- 4 -BRIEF DESCRIPTION OF THE DRAWINGS
Embodiments of the invention will now be described, by way of example, with reference to the following drawings in which:-Figure 1 is a side view of one embodiment of the invention;
Figure 2 is a perspective view of a support member shown in Figure 1;
Figure 3 is an end of a second type of support member; and Figure 4 is an end view to illustrate use of a different type of support member.
The same reference numerals are used for like parts throughout.
DETAILED DESCRIPTION
Referring to Figure 1, a rotatable cylindrical member 2 is supported by two spaced-apart support members 4 and 6 so as to be capable of rotating freely if a bird lands thereon. In this way an unstable perch is provided.
The cylindrical member 2 is supported on support members 4 and 6 by means of centrally located axle rods 8 and 10.
In Figure 2, a support member 4 is shown in perspective view to be a clamp in the shape of an inverted U with an upstanding or vertical portion 12 for the axle rod 8. The depending legs 14 and 16 of the U-shaped support member 4 are each drilled in their approximate centre to form a respective internally threaded hole through which an externally threaded rod 18 passes. The rod is provided with a handle portion 22.

DETAILED DESCRIPTION
Referring to Figure 1, a rotatable cylindrical member 2 is supported by two spaced-apart support members 4 and 6 so as to be capable of rotating freely if a bird lands thereon. In this way an unstable perch is provided.
The cylindrical member 2 is supported on support members 4 and 6 by means of centrally located axle rods 8 and 10.
In Figure 2, a support member 4 is shown in perspective view to be a clamp in the shape of an inverted U with an upstanding or vertical portion 12 for the axle rod 8. The depending legs 14 and 16 of the U-shaped support member 4 are each drilled in their approximate centre to form a respective internally threaded hole through which an externally threaded rod 18 passes. The rod is provided with a handle portion 22.
- 5 -In use, the support members 4 are fitted over, for example, the ledge 24of a balcony (Figure 1) of an apartment and the handles 22 turned so that the support members 4 and 6 clamp on the ledge 24. The cylindrical member 2 is thus located above the surface of the ledge 24 at such a position that a bird can not alight between the cylindrical member 2 and the surface of the ledge 24.
In Figure 3, part of a second embodiment is shown.
A support member 4 is made with an axle rod protrusion 8 on both sides of the vertical portion 12.
In Figure 4 a still further embodiment is shown in which the support members 4 and 6 are L-shaped in side view and provided with bolts 26 to fasten them to the top surface of the ledge (usually formed of concrete).
It will be readily apparent to a person skilled in the art that a number of variations and modifications can be made without departing from the true spirit of the invention which will now be pointed out in the appended claims.
