Methods and mechanical apparatus for deterring birds

A mechanical apparatus for deterring birds from landing at undesirable perch locations comprising:

• a structurally supportive base having a first support member fixed onto said base;
• a carriage assembly including,
• a core, said core having a central opening to axially adjoin and mate with said first support member at a bearing surface provided within said opening,
• a guide bearing, rotatably mounted about and contiguous with said first support member,
• a locking collar, contiguous with said core and said guide bearing,
• a base plate, rotatably mounted about and contiguous with said core and said locking collar;
• and
• a multiplicity of horizontally disposed rods, of stainless steel or rigid plastic or metal material, mechanically attached to said base plate and projecting radially outward from said base plate;
• and
• a coil latch attached to said supportive base with said coil latch initially engaging said carriage assembly and located adjacent to said carriage assembly after so engaging.

• a base plate, rotatably mounted about and contiguous with said core and said locking collar wherein said base plate has a multiplicity of ports, each port engaging a rivet, said rivets positioned within said ports and securing said multiplicity of rods to said base plate, said base plate also having a multiplicity of grooved notches adjacent to and surrounding each of said ports, said grooved notches engaging said rods;
• and
• a multiplicity of horizontally disposed rods, of stainless steel or rigid plastic or metal material, mechanically attached to said base plate and projecting radially outward from said base plate.

A mechanical apparatus for deterring birds from landing at undesirable perch locations comprising:

• a pivot pin;
• a carriage, having a first aperture and a central shaft, said first aperture and said central shaft axially adjoining said pivot pin;
• a bearing, placed on said carriage within said first aperture and contiguous with said pivot pin;
• a multiplicity of rods, placed on said carriage and projecting outward therefrom;
• a retaining member, placed on said carriage and engaging the multiplicity of rods thereon;
• and
• a pushnut, attached to said carriage and contiguous with said retaining member.

A method for deterring birds from landing at undesirable perch locations, the method comprising the steps of:

• placing a multiplicity of rods upon a carriage, said carriage comprised of a multiplicity of recessed slots for said multiplicity of rods, said carriage having a central shaft for rotation;
• securing said multiplicity of rods to said carriage by a retaining member;
• fastening said retaining member to said carriage by a pushnut;
• mounting said carriage onto a pivot pin, said carriage engaging said pivot pin along a mutually concentric axis permitting rotation of said carriage, said pivot pin having a notch therein and a locknut positioned on said notch;
• and
• placing a portion of said pivot pin onto a base support, said base support being in contact with said locknut.
