Abstract

Systems and methods for resisting intrusion by a pest include a reservoir extending between a proximal end and a distal end, and the reservoir defining an interior. A basin is mounted to the reservoir. The basin has a basin body and a basin surface. A sleeve assembly has a sleeve body and a port defined in the sleeve body. A tensioner translationally mounts the sleeve body relative to the basin body. The sleeve body translates distally from an accessible position to an occluded position when a weight applied to the sleeve assembly exceeds a weight threshold set by the tensioner. The accessible position includes bird food on the basin surface being accessible through the port. The occluded position includes the port being disposed distal to the basin surface such that the bird food on the basin surface is inaccessible through the port.

First claim

What is claimed is:

1. A bird feeder resistant to intrusion by a pest, the bird feeder comprising:
a reservoir extending between a proximal end and a distal end, the reservoir defining an interior;
a dispenser mounted to the distal end of the reservoir, the dispenser having a cavity;
a basin having a basin body and a basin surface, the basin mounted to the dispenser;
at least one dispensing surface disposed relative to the dispenser and the basin surface;
a dispensing opening through which bird food is dispensable from the cavity onto the basin surface using the at least one dispensing surface;
a sleeve assembly having a sleeve body and a port defined in the sleeve body;
a tensioner disposed in a cover within the interior of the reservoir, the tensioner translationally mounting the sleeve body relative to the basin body, the sleeve body translating distally from an accessible position to an occluded position when a weight applied to the sleeve assembly exceeds a weight threshold set by the tensioner, the accessible position including the bird food on the basin surface being accessible through the port, the occluded position including the port being disposed distal to the basin surface such that the bird food on the basin surface is inaccessible through the port;
a cap assembly connected to the proximal end of the reservoir, the cap assembly including a hanger and a hanger bar, the hanger passing through an opening in the hanger bar with a stop at a distal end of the hanger being unable to pass through the opening such that the hanger is configured to freely translate relative to the cap assembly;
an adjuster controlling the weight threshold set by the tensioner, the adjuster disposed exterior to the sleeve assembly; and
an indicator disposed in the interior of and visible through the reservoir, the indicator providing a visual reference of the weight threshold.

2. The bird feeder of claim 1 , wherein the sleeve assembly includes a perch extending from the sleeve body relative to the port.

3. The bird feeder of claim 1 , wherein the occluded position includes the port being at least partially occluded by the basin body.

4. The bird feeder of claim 1 , wherein the basin is mounted to the dispenser with a basin mount.

5. The bird feeder of claim 4 , wherein the basin mount includes the at least one dispensing surface.

6. The bird feeder of claim 1 , wherein the tensioner includes a spring extending about a post, a tension of the spring setting the weight threshold.

7. The bird feeder of claim 6 , wherein the adjuster rotates the post, thereby adjusting the tension of the spring.

8. The bird feeder of claim 7 , wherein the indicator moves along an indicator section of the post as the adjuster is rotated.

9. The bird feeder of claim 1 , wherein the port is one of a plurality of ports defined in the sleeve body.

10. A bird feeder resistant to intrusion by a pest, the bird feeder comprising:
a reservoir extending between a proximal end and a distal end, the reservoir defining an interior;
a basin mounted to the reservoir, the basin having a basin body and a basin surface, the basin body including a side surface extending about the basin surface, the side surface being entirely solid and continuous from a proximal edge to a distal edge, such that the side surface extends about a center of the basin body without openings;
a sleeve assembly having a sleeve body and a port defined in the sleeve body;
a tensioner translationally mounting the sleeve body relative to the basin body, the sleeve body translating distally from an accessible position to an occluded position when a weight applied to the sleeve assembly exceeds a weight threshold set by the tensioner, the accessible position including bird food on the basin surface being accessible through the port, the occluded position including the port being disposed distal to the basin surface such that the bird food on the basin surface is inaccessible through the port.

11. The bird feeder of claim 10 , wherein the basin is indirectly mounted to the reservoir.

12. The bird feeder of claim 11 , wherein the basin is indirectly mounted to the reservoir with one or more of a dispenser and a basin mount.

13. The bird feeder of claim 10 , wherein the tensioner includes a spring extending about a post, a tension of the spring setting the weight threshold.

14. The bird feeder of claim 10 , wherein the weight threshold is controlled by an adjuster accessible from an exterior of the bird feeder.

15. The bird feeder of claim 10 , wherein an indicator provides a visual reference of the weight threshold.

16. The bird feeder of claim 10 , wherein the side surface is disposed distal to the port in the accessible position and the side surface at least partially occludes the port in the occluded position.

17. The bird feeder of claim 10 , wherein the port is one of a plurality of ports defined in the sleeve body.

18. The bird feeder of claim 10 , wherein a basin opening is defined in the basin surface, the tensioner extending through the basin opening.
