Abstract
A bird feeder comprises an inner housing including a seed reservoir having at least one feed port defined therethrough, and an inner base supporting the seed reservoir. An outer housing of the feeder is moveably mounted to the inner housing, and includes a reservoir cover arranged over the seed reservoir and defining at least one feed opening. The outer housing is moveable relative to the inner housing between a first position and a second position. A tension spring is operatively connected between the inner housing and a base of the outer housing for biasing the outer housing into the first position relative to the inner housing.
Claims20
A bird feeder comprising:
- an inner housing, including a seed reservoir having at least one feed port defined therethrough for providing access to seed contained within the seed reservoir;
- an outer housing moveably mounted to the inner housing and including a reservoir cover arranged over the seed reservoir and defining at least one feed opening, the outer housing moveable relative to the inner housing along a central axis of the feeder between a first position, wherein the at least one feed port and the at least one feed opening are aligned, and a second position, wherein the at least one feed port and the at least one feed opening are not aligned and the outer housing covers the feed port;
- and
- a tension spring operatively connected to the inner housing and the outer housing for biasing the outer housing into the first position relative to the inner housing, wherein the application of a predetermined force on the outer housing is operative to bias the outer housing into the second position against an elastic return force of the compression spring.
A bird feeder comprising:
- an inner housing having a seed reservoir and at least one feed port for accessing an interior of the seed reservoir;
- an outer housing arranged over the inner housing and including at least one feed opening, the outer housing moveable relative to the inner housing between a first position, wherein the at least one feed port and the at least one feed opening are aligned, and a second position, wherein the at least one feed port and the at least one feed opening are not aligned;
- and
- an elastic return assembly arranged below the seed reservoir and biasing the outer housing into the first position relative to the inner housing.
