Branched spike bird deterrent
A bird deterrent has a base and at least one branched spike extending from the base. The branching can occur anywhere along the spike, and a single branch point can give rise to multiple branches. Spikes can have multiple branches. The various branches can be of any suitable length(s), and can be oriented in any suitable direction(s).
1. A bird deterrent for attachment to a surface, comprising:
an elongated base from which extend a plurality of ribbed spikes, each of which has a trunk having ribs that extend continuously along substantially all of a length of the spikes and that radiates from a core of the spike, wherein the ribs are evenly spaced apart about the core, and where the base has a longitudinal channel extending along a lower surface of the base; and
wherein the base and the plurality of spikes comprise a continuous common plastic material.
2. The deterrent of claim 1 , wherein at least some of the plurality of spikes are branched.
3. The deterrent of claim 2 , wherein the plurality of spikes each extends from the base at an angle that is non-orthogonal to the base, and wherein the branched spikes have a branch that is orthogonal to a bottom of the base.
4. The deterrent of claim 2 , wherein at least some of the plurality of spikes are both un-branched and non-orthogonal to a bottom of the base.
5. The deterrent of claim 1 , wherein there are two spikes extending from a given longitudinal position along the base.
6. The deterrent of claim 1 , wherein branched ones of the plurality of spikes alternate along a length of the base with non-branched ones of the plurality of spikes that arc non-orthogonal with respect to the base.
7. The deterrent of claim 1 , wherein the plastic material comprises polycarbonate.
8. The deterrent of claim 1 , wherein at some position along the base one of the plurality of spikes has a different number of ends from another of the plurality of spikes.
9. The deterrent of claim 1 , wherein the longitudinal channel terminates at an open longitudinal end of the base.
10. The deterrent of claim 9 , wherein the base has a plurality of break points.
11. The deterrent of claim 1 , wherein the base comprises a semi-circular vertical cross-section.
12. The deterrent of claim 1 , wherein at least some of the spikes extend orthogonally from an upper surface of the base.
13. The deterrent of claim 1 , wherein at least some of the spikes collectively form a fan-shaped configuration.
14. The deterrent of claim 13 , wherein the fan-shaped configuration comprises five spikes extending from the base.
15. The deterrent of claim 1 , wherein at least one of the spikes has at least three ends.
