BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to bird feeders and more particularly to a bird feeder including a pushbutton activated positioning mechanism for fastening or unfastening a rope, and a hinged cover which can be releasably secured to a seed container by a latch, together adapted to prevent the cover from being accidentally disengaged from the seed container.
2. Description of Related Art
Bird feeders are known and are customarily used to contain feed seeds to be made available and accessible to birds in an attractive manner. Bird feeders typically have a hinged cover or a rotary cover. It is difficult of placing feed seeds in a seed container of the bird feeder having the rotary cover. Thus, most commercially available bird feeders have a hinged cover.
However, a drawback of the bird feeder having a hinged cover is the weak attachment of the cover and the seed container. It is often that the cover may be accidentally disengaged from the seed container. Another drawback of the bird feeder having a hinged cover is that it is difficult of repairing the bird feeder and mounting same again if such disengagement occurs. This is because typically a bird feeder is installed at a place above the ground for preventing rodents or other animals from approaching and the place is far away from people living areas.
Thus, the need for improvement still exists.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 to 9, a bird feeder in accordance with a first preferred embodiment of the invention comprises a feeding pan 1, a seed container 2 on the feeding pan 1, and a cover 5 on the seed container 2. The seed container 2 includes a feeding chamber 3 hingedly secured to the cover 5, and a discharging chamber 4 releasably secured to the feeding chamber 3 and the feeding pan 1 respectively. The discharging chamber 4 includes a plurality of openings 40 on a bottom edge. The cover 5 includes a central rope 52. The feeding pan 1 includes a cylindrical wall 10 around the discharging chamber 4, and a central boss 11 inside the wall 10 and having a center secured to a first end of the rope 52, a decorated perch 14 along an edge, and three spaced drain holes 15 through the wall 10. Excess water in the seed container 2 may flow through the drain holes 15 to the sloped bottom of feeding pan 1 for draining. This can prevent the contents in the seed container 2 from be damaged due to moisture accumulation.
As shown in FIGS. 1 and 2 specifically, the cover 5 further comprises a hub 51 extending upward and a lateral receptacle 50 in the hub 51 for the receipt of a positioning mechanism 6 which includes an open cavity 60, a first biased button 62 in the cavity 60 and partially extending out of the receptacle 50, and a longitudinal hole 61 through the cavity 60. The rope 52 passes through the longitudinal hole 61 and the hub 51 to extend out of the cover 5.
The first biased button 62 normally maintains its set position to fasten the rope 52 when released by an operator. Further, the first biased button 62 may spring into another position to unfasten the rope 52 when pressed by the operator.
As shown in FIGS. 2, 4 and 5 specifically, the feeding chamber 3 includes a plurality of sliding grooves 30 on an inner surface adjacent to a bottom edge, each sliding groove 30 having a projection 300 on a bottom. The discharging chamber 4 includes a plurality of spaced rails 41 on an outer surface adjacent to a top edge, the rail 41 having a recess 410 on a bottom, and an outwardly extending sealing ring 43 on the top edge, the sealing ring 43 having a height equal to that of the rail 41. The projection 300 is lockingly disposed in the recess 410 when the rail 41 slides into the sliding groove 30.
As shown in FIGS. 2, 5 and 6 specifically, the discharging chamber 4 further comprises three protrusions 44 extending inward from a bottom edge, each protrusion 44 having a well 440 on an intermediate portion. The boss 11 comprises three spaced apart protuberances 12 extending outwardly from a bottom edge, each protuberance 12 having a sliding trough 13 with a projecting member 130 on an intermediate portion. The projecting member 130 is complimentarily engaged with the well 440 when the protrusion 44 is disposed in the sliding trough 13. Each opening 40 is disposed between two adjacent protrusions 44. The wall 10 is disposed around joining portions of the sliding troughs 13 and the protrusions 44.
As shown in FIGS. 2, 3 and 4 specifically, the cover 5 further comprises two parallel adjacent holed members 53, and the feeding chamber 3 further comprises a hinge shaft 32 and a compression spring 33 put on the hinge shaft 32 and having a first end urging against the feeding chamber 3. The hinge shaft 32 has two ends passing through the holed members 53 with a second end of the compression spring 33 urging against an inner surface of the cover 5. The cover 5 further comprises a latch 54 extending downward and being opposite to the holed members 53. The feeding chamber 3 further comprises a recessed member 35 on an upper edge opposite to the hinge shaft 32, and a second biased button 34 disposed in the recessed member 35. Also, the latch 54 is releasably fastened in the recessed member 35 by the second biased button 34 and in a normal position, the latch 54 is fastened by the second biased button 34. Two rubber pads 36 are provided on the top edge of the feeding chamber 3 with the recessed member 35 disposed therebetween.
As shown in FIG. 8 specifically, an operator may press the first biased button 62 to spring it into another position to unfasten the rope 52. Further, the operator may press the second biased button 34 to unfasten the latch 54. Furthermore, the operator may clockwise pivot the cover 5 with respect to the seed container 2 about the hinge shaft 32 to open the seed container 2.
As shown in FIG. 9 specifically, once the cover 5 is open, the operator may counterclockwise pivot the cover 5 with respect to the seed container 2 about the hinge shaft 32 to close the seed container 2 with the rope 52 being fastened by the first biased button 62 and the latch 54 being fastened by the second biased button 34 respectively.
It is envisaged by the invention that it is possible of preventing the cover 5 from being accidentally disengaged from the seed container 2.
Referring to FIG. 10, a bird feeder in accordance with a second preferred embodiment of the invention is shown. The characteristics of the second preferred embodiment are substantially the same as that of the first preferred embodiment except the following: the cover 5 comprises two bent bifurcated members 7 on an inner surface. The bent bifurcated member 7 includes a hinge shaft 70 through one part. The feeding chamber 3 comprises two holed members 37 on an inner surface each with the hinge shaft 70 mounted through to hingedly secure the cover 5 to the feeding chamber 3. Thus, an open or closing operation of the cover 5 is made easier.
Referring to FIG. 9, a bird feeder in accordance with a third preferred embodiment of the invention is shown. The characteristics of the third preferred embodiment are substantially the same as that of the first preferred embodiment except the following: Four M-shaped clasps 16 are provided on the feeding pan 1 on a bottom. The M-shaped clasp 16 includes a sliding groove member 160. The discharging chamber 4 includes two rail members 44 on a bottom, the rail members 44 being configured to slide into the sliding groove members 160 to assemble the feeding pan 1 and the discharging chamber 4. This is simpler and easier. While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
