The present invention relates to bird feeders and, more particularly, to a thistle bird feeder designed and developed to make the feeding of smaller birds easier, cleaner, and more useful to the caretaker.
Thistle bird feeders have been around for a long time and are known in the art. These types of feeders are typically used with smaller seeds such as, for example, thistle seeds or similar sized type seeds. The seeds are generally poured into and housed in a container where they are made available to birds through small holes or similarly sized openings in the container or some form of provided polyester sock or wire mesh. The thistle bird feeder is then hung for ease of access by the birds. Small birds such as finches can then either perch adjacent to the container or stand on the sock or wire mesh and eat the small seeds through the openings.
One of the problems with these type of feeders is that when the bird feeder becomes empty, the bird feeder must be retrieved from where it is hanging, necessary components or parts of the bird feeder opened or removed to obtain access to the container, replenishing the seeds into the container or sock or wire mesh, and/or having to replace the entire container, sock, or wire mesh altogether, and then re-hanging the bird feeder. This process of re-filling the bird feeder is cumbersome and not convenient. Applicant has, however, designed a thistle bird feeder that solves these problems and provides other useful benefits. Thus, there is a need and there has never been disclosed Applicant's unique thistle bird feeder.
The present invention is a thistle bird feeder comprising a container and a plurality of feeder bags. A cable extends through the container and is provided with a hanging loop at one end and a stopper at the other end for retaining the components of the bird feeder between them and suspending the bird feeder in a hanging position when hung from a tree or otherwise. The container comprises and is formed by a cover, a dome, and a collar. The cover is provided with a star shaped opening that frictionally engages with the hanging cable for enabling the separation of the cover from the dome to fill the bird feeder when the bird feeder is in the hanging position. The collar comprises a plurality of divider walls for creating a plurality of sections or compartments to direct or funnel the bird feed into individually separated feeder bags corresponding to each section or compartment when filling the bird feeder. Adjacent each section or compartment is a telescoping column and a plurality of hooks for releaseably attaching or fastening to an elastic band secured to the feeder bag.
The Description of the Preferred Embodiment will be better understood with reference to the following figures:
Turning to
As illustrated, the bird feeder 20 is filled with bird seed 34 which includes but is not limited to various thistle seeds or any other type of similar sized bird seed. This seed is made available to birds 36 standing or perched directly on the feeder bags 24.
The components of the bird feeder 20 and the assembly of these components are more clearly illustrated in
To use the locking means 38, the ledge 46 of the latch 40 is inserted through the latch hole 58 and into the chamber 60. The ledge 46 is then moved in the direction of arrow A toward sidewall 62. The sidewall 62 acts as a stopping means for preventing the ledge 46 from moving any further within the chamber 60. As the ledge 46 is moved in the direction of arrow A, the ledge 46 encounters a detent member 66 which requires additional pressure to force the ledge 46 past the detent member 66 to reach the sidewall 62 and a locked position. When the ledge 46 reaches the sidewall 62, the sidewall 62 and the detent member 66 coact to prevent the ledge 46 from being easily or accidentally bumped or pushed in either direction from this locked position. Also, while the ledge 46 is in the chamber 60 and moving toward the locked position, the bottom surface 52 of the exterior edge 42, the recessed wall 44 of the latch 40, and the top surface 50 of the ledge 46 collectively become engagingly mated with the rim 56 for completing the locking means 38 and achieving a secure, waterproof seal and fit between the cover 28 and the dome 30. This locking means 38 is also designed to prevent the undesired rotation of the cover 28 in relation to the dome 30. When the locking means 38 is desired to be released, the reverse procedure is followed. The sidewall 64 then acts as the stopping mechanism to stop the movement of the ledge 46 within the chamber 60 for alignment in tandem with the latch hole 58 for removal of the ledge 46 back through the latch hole 58 and releasing the cover 28 from the dome 30.
In the preferred embodiment, this locking means 38 is used in four equally spaced locations around the perimeter of the cover 28 and the dome 30 for achieving the most efficient and secure attachment of the cover 28 to the dome 30. Alternatively, it is contemplated that any number of locking means 38 may be used by one skilled in the art.
To assist in the handling and movement of the cover 28, a raised cap 68 is used (
In the preferred embodiment, the raised cap 68 is also provided with a star shaped opening 74 having a center 76 and a plurality of slits 78 forming a plurality of adjacent teeth. Penetrating through the center 76 of the star shaped opening 74 is the hanging cable 26 (see also
When the cover 28 is released from the dome 30, as illustrated, the cover 28 can be raised or elevated anywhere along the hanging cable 26 up to and adjacent the locking crimp 82 of the hanging loop 80. This creates a separation distance 84 from the dome 30. As the cover 28 is being raised or elevated, the force being applied on the cover 28 to raise or elevate the cover 28 is sufficient to overcome the frictional engagement between the hanging cable 26 and the star shaped opening 74 within the cover 28. When the cover 28 reaches a desired position along the hanging cable 26, the frictional engagement between the hanging cable 26 and star shaped opening 74 is sufficient to overcome the gravitational pull on the cover 28 and thereby freely retain the cover 28 in that desired position on the hanging cable 26. In this manner, the separation distance 84 created between the cover 28 and the dome 30 enables the bird seed 34 to be poured into the open top 54 of the dome 30 for filling or re-filling the bird feeder 20. This process is preferably accomplished while the bird feeder 20 is being hung. Alternatively, this process may be accomplished after the bird feeder 20 has been retrieved from the location that it is being hung. When the process is reversed and the cover 28 is lowered along the hanging cable 26 and reattached to the dome 30, the cover 28 and dome 30 again unite to provide a waterproof seal for protecting the bird seeds 34 from the elements.
At the other end of the dome 30, the dome 30 is releaseably attached or fastened to the collar 32 using a fastening means 86, as illustrated in
To use the fastening means 86, the dome 30 is slid over the outer surface 94 of the collar 32 until the recessed hole 88 is positioned above the ledge 96. When this occurs, the dome 30 is pressed against the outer surface 94 of the collar 32 until the ledge 96 is penetrated through the recessed hole 88. The sidewalls 92 likewise become frictionally engaged with the sides of the ledge 96. At the same time, a portion 106 of the dome 30 is frictionally received and held between the flat bottom surface 102 of the ledge 96 and the brim 98 for completing the fastening means 86 and achieving a secure, waterproof seal and fit between the dome 30 and the collar 32. A cross-section of this attachment is further illustrated in
When the fastening means 86 is desired to be released, depressing upon the tapered top surface 100 of the ledge 96 will force the outer surface 94 to push away from the dome 30 and the ledge 96 to push away from the recessed hole 88 for releasing the ledge 96 from the recessed hole 88. As this occurs, the portion 106 of the dome 30 simultaneously becomes released from the frictional engagement between the flat bottom surface 102 of the ledge 96 and the brim 98. In the preferred embodiment, the depression can be caused by a person's finger, a screw-driver, or any other means known to one skilled in the art. Additionally, the sloping wall 90 is designed to slope inwardly toward the tapered top surface 100 of the ledge 96. In this manner, the sloping wall 90 permits easier access to the ledge 96 and directionally guides any depression means directly to the ledge 96. To accommodate the depression movement of the outer surface 94 and the ledge 96 to push away from the dome 30, the collar 32 is provided with a V-shaped internal wall 108 that provides a spacing cushion 110 to account for and enable this movement. Once completed, the dome 30 is released from the collar 32.
In the preferred embodiment, this fastening means 86 is used in four equally spaced locations around the perimeter of the dome 30 and collar 32 for achieving the most efficient and secure attachment of the dome 30 to the collar 32. Alternatively, it is contemplated that any number of fastening means 86 may be used by one skilled in the art.
Inside the collar 32 there is comprised an inner wall 112 that supports a plurality of divider walls 114 separating the collar 32 into a plurality of sections or compartments 116. In the preferred embodiment, the plurality of divider walls 114 is four which creates an equal number of plurality of sections or compartments 116 of four. Alternatively, the plurality of divider walls 114 may be two, as illustrated in
The combination of the dome 30 and the collar 32 provide a width that is sufficiently large to assist in providing a covering means for the birds 36 when the birds 36 are standing or perched on the feeder bags 24. This covering means assists in protecting the birds 36 from the elements such as rain, snow, sun, or otherwise when the birds 36 are feeding.
Turning to
In the preferred embodiment, the feeder bag 24 is preferably made of a polyester or nylon mesh sock or any other suitable material that accomplishes the purposes described herein and is known to one skilled in the art. The feeder bag 24 may comprise any variation of size, shape, or contain any desired volume of bird seed 34. The feeder bag 24 is releaseably attached or fastened to the collar 32 using attachment means 128, as illustrated in
To use the securing means 146, the elastic band 142 is stretched from a normal flex to an expanded flex for enlarging the opening 154 in the feeder bag 24 and the elastic band 142 to fit around the exterior wall 134 of the telescoping column 130 and the plurality of hooks 132 surrounding the telescoping column 130. When this occurs, the enlarged feeder bag 24 and expanded flex of the elastic band 142 are slid upwardly and over the plurality of hooks 132. The stretching or expanded flex of the elastic band 142 is then released allowing the elastic band 142 to return to the normal flex around the exterior wall 134 of the telescoping column 130. In the preferred embodiment, the normal flex of the elastic band 142 retains some elasticity and compression force on the exterior wall 134 of the telescoping column 130. Alternatively, the elastic band 142 may not provide much, if any, compression force on the exterior wall 134 of the telescoping column 130. Once the elastic band 142 and the feeder bag 24 are fitted over the telescoping column 130, the elastic band 142 is pulled downwardly into each of the pockets 140 in each of the plurality of hooks 132 surrounding the telescoping column 130. In this manner, the pockets 140 coact to secure the proximal end 144 of the feeder bag 24 to the telescoping column 130. The feeder bag 24 remains secured to the telescoping column 130 until a replacement feeder bag 24 is needed.
Turning back to
The stopper 160 may be any component and connected or attached to the hanging cable 26 by any means known to one skilled in the art provided that the stopper 160 is sufficiently connected or attached to the hanging cable 26 to support the gravitational pull and weight of the bird feeder 20 when hung.
Upon hanging the bird feeder 20 from a tree branch or, alternatively, from any desired location, the gravitational pull and weight of the bird feeder 20 will force or pull the bird feeder 20 in a downward direction on the hanging cable 26. As this occurs and the hanging cable 26 remains in the hanging position, the stopper 160 will be forced to engage with and become gravitationally mated with the base 158 of the vertical tube 118. In this manner, the bird feeder 20 and all of the assembled components are freely hung and suspended as desired.
To fill the bird feeder 20 with bird seed 34 and assuming that all of the components of the bird feeder 20 are assembled as described herein, the bird feeder 20 may be in the hanging position as hung by the hanging cable 26 from the hanging loop 80 or, alternatively, on a table or other supporting means known to one skilled in the art. If in the hanging position, the cover 28 is then separated from the dome 30 as previously described in conjunction with
Should any of the feeder bags 24 become unusable, the use of plurality of sections or compartments 116 supplying the other feeder bags 24 prevents the bird feeder 20 from losing all of the loaded bird seed 34 to the ground from or through the one individual, unusable or leaking feeder bag 24. A feeder bag 24 could become unusable through an excessive larger hole being created in it, being torn down by a squirrel or other rodent, etc. . . . Once in place, the bird feeder 20 can hold a large amount of bird seed 34 for automatically feeding seed into each of the individual feeder bags 24 below. In this way, the caretaker can fill the bird feeder 20 and the feeder bags 24 much less frequently. When an individual feeder bag 24 becomes emptied by the birds, the individual feeder bag 24 is automatically and continually refilled until the bird feeder 20 and corresponding section or compartment 16 serving the feeder bag 24 becomes empty.
Thus, there has been provided Applicant's unique thistle bird feeder. While the invention has been described in conjunction with a specific embodiment, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications and variations as fall within the spirit and scope of the appended claims.
