Abstract
The device employs flying bodies imitating at least a pair of birds of prey, such as falcons, catching foraging birds, such as crows, rotated by a vertical axis wind driven mechanism mounted via a bearing to the support pole in an area from which unwanted birds are to be removed. The device is responsive to even the slightest breeze to rotate unidirectionally regardless of the wind direction, consequently producing a mixture of visual, sonic and light reflective deterrent effects. A simple and robust mobile ground anchor assembly significantly reduces the time and effort required for installation, removal and maintenance of the device.
Description
Wind rotated bird scaring device FIELD OF THE INVENTION
The present invention relates to bird scaring devices, and, more particularly, to wind rotated bird scaring devices.
BACKGROUND
The rotating bird scaring devices are widely used to remove unwanted birds from landfills, agricultural fields, airfields, marine structures and buildings to minimize economic damage.
However, existing rotating deterrents generally require an external power source to operate.
Less common, but the most desirable to implement are deterrents which utilize the natural forces of the wind to rotate. Hence, such devices are more cost efficient and environmentally friendly.
DESCRIPTION OF PRIOR ART
The related art is represented by the following patents of interest.
Doty, Turkewitz, Olson and Spies, U.S. Pat. No.7,930,989 describes a wind rotated assembly for repelling birds from a selected area by means of bird scaring holographic images, noises, and light reflective effects.
Suelzer, U.S. Pat. No. 6,941,886 discloses a wind rotated marine pest deterrent which includes a hub rotatably connected to the platform and at least one arm extending radially from the hub. Each arm further includes a wind collector at an end opposite of the hub.
[0008] Watermann, U.S. Pat. No. 6,807,765 discloses a bird scaring device comprising a silhouette of a bird of prey having at least one hole there through such that the device is rotatably moved by the wind.
Rousseau, Jr., U.S. Pat. No. 4,131,079 discloses a wind rotated bird scaring device which is formed from an elongated, vertically extending post; a resilient wire mounted on, and extending from, the upper end of the post; and a pair of large, thin, light weight, highly light reflective discs rotatably suspended from the remote end of the wire in cantilever fashion and responsive to wind forces on the discs in order to provide a random, distracting motion as well as to cast darting light reflections in a random, erratic manner on the area surrounding the post.

Huffman and Peck, U.S. Pat. No. 1,167,502 discloses another rotating wind driven silhouette illustrated as a cat, which acts as a scarecrow. It may also include bells, which ring as the silhouette is moved.
However, these prior art devices have the disadvantage of providing only limited deterrent effect.
Thus, there is a need for a more efficient bird scaring device which provides multiple deterrent effects, which utilizes the natural forces of the wind to function, which is environmentally friendly and harmonious, which is economical to manufacture and which can be easily installed or removed from the field as necessary.
The present invention is intended to satisfy that need.
OBJECTS OF THE PRESENT INVENTION
The main object of the present invention is to create a new and more practical bird scaring device, by overcoming the limitations of the known apparatuses.
Another object of this invention is to increase a bird scaring device's efficiency by employing a mixture of visual, sonic and light reflective deterrent effects.
It is a further object of the invention is to produce a bird scaring device rotated by a novel vertical axis wind driven mechanism.
Lastly, it is an object of the present invention to produce a new robust, cost-effective and environmentally friendly bird scaring device, which does not require complex ground anchoring means and thus can be easily relocated from place to place as desired and may be quickly installed or dismantled.
These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.
SUMMARY OF THE INVENTION
The present invention provides the wind rotated bird scaring device to get rid of unwanted birds from landfills, agricultural fields, airfields, buildings and other structures to minimize economic losses and to reduce the hazards to air traffic.
In the shown embodiment, the device employs multiple non-lethal deterrent techniques producing visual, sonic and light reflective deterrent effects.
Specifically, the device comprises flying bodies imitating at least a pair of birds of prey such as falcons catching foraging birds such as crows, a vertical axis wind driven rotating mechanism mounted via bearing to the support pole in an area from which unwanted birds are to be removed, and a mobile ground anchor assembly.

In the shown embodiment, the device employs multiple non-lethal deterrent techniques producing visual, sonic and light reflective deterrent effects.
Specifically, the device comprises flying bodies imitating at least a pair of birds of prey such as falcons catching foraging birds such as crows, a vertical axis wind driven rotating mechanism mounted via bearing to the support pole in an area from which unwanted birds are to be removed, and a mobile ground anchor assembly.
The vertical axis wind driven rotating mechanism, which is believed to be novel, is a new version of the wind turbine disclosed in my Canadian Patent 2,602,288 that has been modified in order to meet the objects of the present invention.
It includes at least one arm (preferably two) with a rotatably attached paddle containing a pair of mutually perpendicularly oriented light reflecting substantially trapezoid-shaped blades which are non-rotatably secured by their big parallel edges to the opposite ends of a shaft. The paddles are limited in their free rotation by the arms within a ninety degree angle. They are responsive to even the slightest breeze to rotate the device unidirectionally regardless of the wind direction, consequently generating bird repelling noises as well as spreading out erratic scaring light reflections on the area surrounding the device.
The flying bodies, imitating birds of prey catching foraging birds, are mounted to the opposite ends of the arm by flexible support elements such as spring hinges.
This enables the flying bodies to move upwardly and downwardly as the device rotates, further adding visual scarring effects to the device.
Each device may be securely attached to the ground by a simple and robust mobile ground anchor assembly. This gives a time advantage for installation, removal and maintenance of the device.

DETAILED DESCRIPTION OF THE INVENTION
The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will become readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide for a novel and improved wind rotated bird scaring device.
The present invention, as best shown in FIG. 1, generally comprises flying bodies 1 imitating at least a pair of birds of prey such as falcons catching foraging birds 2 such as crows, a vertical axis wind driven rotating mechanism mounted via bearing to the support pole 3 in an area from which unwanted birds are to be removed, and a mobile ground anchor assembly.
A vertical axis wind driven rotating mechanism (FIGS. 1-5) employs at least one, preferably two horizontally oriented arms 4, which are fixedly and symmetrically mounted to a vertically oriented hub 5, and a set of rotating paddles 6.
Each of the paddles 6, as illustrated in FIG. 2, consists of a shaft 7 and a pair of light reflecting substantially trapezoid-shaped blades 8. The blades 8 are non-rotatably secured by their big parallel edges 9 to both ends of the shaft 7 in a mutually perpendicular orientation. Such orientation of blades 8 creates a maximum drug force by vertically oriented blades, while producing practically no friction by horizontally oriented blades.
As a result, the paddles 6 are responsive to even the slightest breeze to rotate the arms 4.
As shown in FIGS. 3 through 5, the paddles 6 are rotatably mounted via bearings, built in the paddle support members 10, to upper sides of arms 4. The paddles 6 are limited in their free rotation by arms 4 within a ninety degree angle. This causes the bird scaring device (FIG.1) to rotate unidirectionally in wind regardless of the wind direction 11 and generate bird repelling noises as well as to spread out erratic scaring light reflections on the area surrounding the device.
The blades 8 may be manufactured from any suitable lightweight, light reflective and strong material.
The vertically oriented hub 5 is rotatably mounted on the upper end of the vertically oriented support pole 3 (FIGS. 1, 3 and 4), the lower end of which is fixed within the selected area.
As illustrated in FIG. 1, the support pole 3 consists of a plurality of threaded tube segments 12 being joined together by couplings 13. Each of the tube segments 12 has a pair of holes 14 at both ends and each coupling 13 has a similar hole 15 in the middle.
These holes allow quick and easy assembling and disassembling of the device by the use of a pair of rods instead of tube wrenches.
The flying bodies 1, imitating birds of prey, are fastened to the respective ends of the at least one arm 4 by flexible support elements 16, such as a spring hinges, in oppositely disposed relationship with respect to each other for causing flying bodies 1 to circle and move upwardly and downwardly as the bird scaring device rotates unidirectionally in wind producing a visual bird scarring effect.
Each of the bodies 2, imitating foraging birds, is attached by a suspension cord 17 or the like to a lower part of each respective body 1, imitating birds of prey. This enables bodies 2 to circle and move in an erratic manner, simulating them being caught by bodies 1 as the bird scaring device rotates unidirectionally in wind further adding a visual bird deterring effect.
The mobile ground anchor assembly, exposed in FIG. 1 and detailed in FIG. 7, consists of a self-drilling ground anchor 18 (illustrated separately in FIG. 6), drilled into the ground 19, and a locking mechanism.
The self-drilling ground anchor 18 is essentially a threaded rod having one end 20 tipped and an opposite end 21 adapted to be driven by a drill (FIG. 6).
The locking mechanism contains a U-shaped metal frame 22 with tapped holes 23 in each end, and a pair of cone point screws 24 inserted into tapped holes 23. The locking mechanism secures the support pole 3 slidably mounted over the self-drilling ground anchor 18 by means of inserting the cone point screws 24 via a plurality of holes 25, located on the lowest tube segment of the support pole 3, and following tightening the cone point screws 24.
The present device surpasses the efficiencies of the known devices by providing multiple deterrent effects and employing the new wind driven rotating mechanism.
Because of its simplicity and durability, it is inexpensive to manufacture, may readily be transported from place to place as desired and may be quickly assembled or dismantled.
This invention covers a wide variety of market segments around the globe, such as agriculture, aviation and landfills to name a few.
Each of the paddles 6, as illustrated in FIG. 2, consists of a shaft 7 and a pair of light reflecting substantially trapezoid-shaped blades 8. The blades 8 are non-rotatably secured by their big parallel edges 9 to both ends of the shaft 7 in a mutually perpendicular orientation. Such orientation of blades 8 creates a maximum drug force by vertically oriented blades, while producing practically no friction by horizontally oriented blades.
As a result, the paddles 6 are responsive to even the slightest breeze to rotate the arms 4.
As shown in FIGS. 3 through 5, the paddles 6 are rotatably mounted via bearings, built in the paddle support members 10, to upper sides of arms 4. The paddles 6 are limited in their free rotation by arms 4 within a ninety degree angle. This causes the bird scaring device (FIG.1) to rotate unidirectionally in wind regardless of the wind direction 11 and generate bird repelling noises as well as to spread out erratic scaring light reflections on the area surrounding the device.
The blades 8 may be manufactured from any suitable lightweight, light reflective and strong material.
The vertically oriented hub 5 is rotatably mounted on the upper end of the vertically oriented support pole 3 (FIGS. 1, 3 and 4), the lower end of which is fixed within the selected area.
As illustrated in FIG. 1, the support pole 3 consists of a plurality of threaded tube segments 12 being joined together by couplings 13. Each of the tube segments 12 has a pair of holes 14 at both ends and each coupling 13 has a similar hole 15 in the middle.
These holes allow quick and easy assembling and disassembling of the device by the use of a pair of rods instead of tube wrenches.
The flying bodies 1, imitating birds of prey, are fastened to the respective ends of the at least one arm 4 by flexible support elements 16, such as a spring hinges, in oppositely disposed relationship with respect to each other for causing flying bodies 1 to circle and move upwardly and downwardly as the bird scaring device rotates unidirectionally in wind producing a visual bird scarring effect.
Each of the bodies 2, imitating foraging birds, is attached by a suspension cord 17 or the like to a lower part of each respective body 1, imitating birds of prey. This enables bodies 2 to circle and move in an erratic manner, simulating them being caught by bodies 1 as the bird scaring device rotates unidirectionally in wind further adding a visual bird deterring effect.
The mobile ground anchor assembly, exposed in FIG. 1 and detailed in FIG. 7, consists of a self-drilling ground anchor 18 (illustrated separately in FIG. 6), drilled into the ground 19, and a locking mechanism.
The self-drilling ground anchor 18 is essentially a threaded rod having one end 20 tipped and an opposite end 21 adapted to be driven by a drill (FIG. 6).
The locking mechanism contains a U-shaped metal frame 22 with tapped holes 23 in each end, and a pair of cone point screws 24 inserted into tapped holes 23. The locking mechanism secures the support pole 3 slidably mounted over the self-drilling ground anchor 18 by means of inserting the cone point screws 24 via a plurality of holes 25, located on the lowest tube segment of the support pole 3, and following tightening the cone point screws 24.
The present device surpasses the efficiencies of the known devices by providing multiple deterrent effects and employing the new wind driven rotating mechanism.
