The present invention relates to a hanger arrangement for articles, such as hanging plant baskets, and which is particularly well adapted to mounting of feeders for birds and other animals (referred to generally hereinafter as “bird feeders,” but being understood as applicable to a feeder for any animal), and more particularly to an apparatus and method for facilitating, and making more sanitary, the replacement of feed to an elevated bird feeder once consumed, and a bird feeder incorporating the aforementioned method and apparatus.
A substantial entirety of bird feeders currently on the market are refilled through the open top of some form of feed hopper, which operation further involves removal of a cover or lid which serves to cover the top opening. A refilling operation can be carried out while the feeder remains in a hanging condition, or after the feeder is taken down from the tree limb or other support. In either case, this is invariably a time consuming and relatively difficult task, requiring the use of a ladder and/or necessitating subsequent re-mounting of the entire feeder to the overhead support. In the winter, especially, this can be an unpleasant experience, and one that potentially discourages many from enjoying the pleasurable and rewarding hobby of bird feeding. Cleaning of, particularly, the feeding stations thereof, where the birds actually feed, is also messy and unpleasant, and if proper cleaning practices are not routinely observed by the user, a potential danger to the birds being fed will be present, in the form of harmful mold, etc.
It would therefore be desirable to provide a structure in a bird feeder which would allow facilitated removal of at least a feed containing reservoir, such as a plastic bottle, of a bird feeder, from a mounting structure remaining in a hanging condition to a tree limb or the like, and subsequent replacement of a feed-filled bottle to the mounting structure following feed replenishment or cleaning.
It would be yet more desirable to provide a bottle/feeding station combination which could be easily removed from a suspended state, discarded or recycled after the feed was exhausted, and replaced with a new pre-filled bottle/feeding station combination which could be installed to an elevated mounted and use-oriented position.
Accordingly, it is an object of the invention to provide a method and structure for use with bird feeders which overcomes the drawbacks of the prior art.
It is a further object of the invention to provide a method and structure for use in a bird feeder which readily permits at least a feed retaining portion of the bird feeder to be removed from and replaced to a hanging mounted condition.
It is still a further object of the invention to provide a method and structure, as referred to above, in an economical form allowing reliable and simple operation.
It is a yet further object of the invention to provide a bird feeder which utilizes the method and structure in accordance with the invention.
In accordance with these and other objects of the invention, there is provided an apparatus and method in accordance with which at least a reservoir-including portion of a bird feeder can be relieved of its mounted hanging condition and replaced thereto in a facilitated manner.
In broad terms, the invention contemplates a structural portion including mounting structure which normally remains in an attached state to an elevated support, such as a tree limb, pole or the like, and to which a bottle or other reservoir for containing feed material (or reservoir assembly, which may optionally also include a feeding station, decorative parts, etc.), is selectively engageable. Advantageously, cooperating structure of the reservoir itself (or alternatively structure carried on any of the other parts making up the reservoir assembly) and the structural portion including the mounting structure, allow coupling and uncoupling of each, preferably in a simplified manner such that the respective operations can easily and readily be carried out with the mounting structure located overhead, and very possibly in a free-swinging state. By virtue of this arrangement, when exhausted of feed, the spent reservoir (or the entire reservoir assembly) can be easily removed from its suspended state, and be either refilled and replaced, or more preferably, simply recycled and replaced with a new pre-filled reservoir/reservoir assembly, in the manner of a cartridge.
Briefly stated, the apparatus according to the invention comprises first and second cooperative portions which can selectively be brought into engagement preventing unassisted separation of one from the other, and out of engagement to permit unencumbered separation, one from the other. The first cooperative portion is carried on a refillable portion of the feeder containing a reservoir, preferably on the bottle itself which contains the feed and which serves as a hopper, and the second cooperative portion is part of a mounting structure affixed, directly or indirectly, to a mounting support (tree, pole, etc.) such that it locates in a position operably accessible by the first portion when held by the user.
Conveniently, the operation of gravity may be utilized to assist in the mutual coupling of the bottle (or bottle assembly) to the mounting structure. In this regard, the second cooperative portion of the mounting structure may include a stop against which a portion of the bottle, configured to achieve such end and which is clearingly received when lifted to a raised position above the stop, shoulders against when lowered by the effects of gravity, thereby preventing further descent of the bottle. With such approach, when separation is desired, the bottle is simply raised above the stop and out of shouldered engagement, and clearingly removed in the same manner in which it was originally installed.
In accordance with a particularly advantageous embodiment, the apparatus according to the invention comprises first and second cooperative portions which can selectively be brought into engagement preventing separation of one from the other, and out of engagement to permit unencumbered separation, one from the other. The first cooperative portion is carried on the refillable portion of the feeder (or other item which is to be dismounted), and the second portion is part of a receiving portion mounted, directly or indirectly, to a mounting support such that it locates in a position operably accessible by the first portion. Either one of the first and second portions includes an opening of suitable non-circular shape (referred to herein as the “female portion”), and the other of the first and second portions includes an engagement portion (referred to herein as the “male portion”) has as outer non-circular shape (the same or different from the non-circular shape of the opening) fittable through the opening of the female portion when selectively oriented relative thereto, but which is blocked from passage when oriented in a different relative orientation owing to the non-circular shape of each.
Advantageously, although not necessarily, the engagement portion (i.e., the male portion) of the given one of the first and second portions of the above embodiment has an outer shape corresponding generally to the opening shape in the female portion of the other of the first and second portions, and which is suitably sized for clearance through the opening when the shapes defined by each are mutually aligned. Selective engagement is established by insertion of the male portion in an insertion direction through the female portion a sufficient distance, such that a side of the male portion opposite an insertion side thereof clears an exit side of the female portion adjacent the opening. When the two portions are then rotationally displaced relative to one another such that their corresponding shapes are no longer in mutual alignment (or removed from at least clearance alignment allowing passage), at least a structural part of the male portion shoulders against a respective portion or portions of the structure of the female portion surrounding the opening, thereby preventing removal of the male portion from the female portion in a direction opposite to an insertion direction.
When separation is desired, the two portions (male and female) are rotationally reoriented relative to one another to bring them into mutual alignment (or into at least clearance alignment), thereby relieving any shouldered interference, such that the male portion again clears the opening for easy removal therethrough.
Some examples of the myriad shapes suitable for use in practice of the embodiment of the invention described immediately above (usable in matched pairs or combinations) include, but are not limited to, rectangle, triangle, star, oval, irregular polygon, etc. Other suitable shapes will of course be dictated by particular design constraints of a product utilizing an embodiment of the invention.
In accordance with an advantageous further variation of this embodiment of the invention, the exit side of the female portion and the side opposite to the insertion side of the male portion (area portions of which are brought into contact engagement when the male and female portions are brought into selective engagement by relative rotation), are provided with respective surface configurations which mutually engage circumferentially to inhibit relative rotation when in gravitationally resting contact engagement, such that relative rotation can only be achieved by upward movement of the male portion, against gravity, in the insertion direction to bring them out of contact engagement a sufficient distance to relieve the circumferential engagement therebetween.
In a particularly advantageous further development of the aforementioned embodiment, the above feature is achieved conveniently in the form of radial pleating which defines a series of wedge-shaped or wave-shaped peaks and valleys on each of the engagement surfaces, and which function akin to an axially facing gear arrangement, when two cooperative portions are mutually engaged.
In an embodiment directed to a bird feeder, and which includes a reservoir portion serving as a hopper for feed and a receiving portion mounted to hang from a mounting support structure, such as a tree limb, a portion or portions of the reservoir conveniently comprises the male portion, and the receiving portion, which remains mounted to a tree limb, etc., includes the female portion. Such feature allows facilitated removal and replacement of the reservoir from a mounted remainder of the feeder (i.e., the receiving portion), for simplified replenishment of feed. It is noted that, because of the structural simplicity and versatility of this mounting mechanism, the general principles described herein can be embodied in a plethora of different bird feeder designs, virtually irrespective of reservoir shape and appearance.
In an alternative embodiment, the above described apparatus and method can be used to mount the entire feeder (or any other article or apparatus, including for example, an animal feeder or a hanging plant basket) to support structure, such as the tree limb (or ceiling or overhang).
In accordance with another embodiment of the invention, the mounting structure takes the form of a hanger including bilateral hook-shaped portions spaced apart from one another by a selected distance forming a bottle receiving opening of predetermined width, the hook-shaped portions being interconnected above over a support which is engageable with a tree limb or the like. A generally T-shaped bottle (a base of the bottle being laterally extended in opposed directions) serves as a reservoir for feed and is received to the hanger in an inverted orientation, with a feeding station attached to an opening of the bottle at an end opposite to the base. A width of the bottle (the diameter, if of a circular cross-section) at its vertical extent above the laterally extended base region is dimensioned to fit between the bottle receiving opening of the hanger, to allow the two lateral extensions of the bottle to be cradled by the corresponding hook-shaped portions when lowered onto them. Removal is accomplished simply by lifting the bottle upwards out of the cradled position, and bringing the bottle free of the hanger through the bottle receiving opening.
In another embodiment, illustrative of just one more of the myriad ways of simply configuring an apparatus in accordance with the invention, the mounting structure includes a horseshoe-shaped member, or portion, which is oriented generally horizontally when the mounting structure is mounted to a support structure for use. The bottle (or reservoir) is tapered from the base to the opening such that a diameter of the bottle in a selected position between the bottle opening and base matches the width opening of the horseshoe. Thus, when the bottle is lifted to a position in which a location therealong (closer to the bottle opening) presents a smaller outer diameter than the horseshoe opening adjacent thereto, the bottle can be inserted laterally into the horseshoe through its laterally-facing opening, and then lowered until the bottle diameter exceeds the inner horseshoe width, and which point the bottle seats thereagainst, preventing further downward movement thereof.
As noted above, the invention is particularly well suited for use in a feeder arrangement having a disposable reservoir and/or entire reservoir-feeding station combination, wherein, after the reservoir (serving as a feed hopper) is exhausted of feed, the empty reservoir can be discarded or recycled (optionally, along with the feeding station). In this regard, is contemplated that in accordance with an advantageous embodiment, a pre-filled reservoir containing bird feed, such as seeds, can be provided as a sealed cartridge for use and replacement as necessary. The reservoir in such case is advantageously an inexpensively produced blow-molded bottle of suitable shape for purposes of operably satisfying the mandates of the invention, and is optionally factory-filled with feed and sealed (with foil seal or the like) to retain integrity and freshness until use. Each bottle would advantageously have a feeding station fitted thereto, such that when replacement of an exhausted bottle was required, the user would simply remove the empty bottle/feeding station from mounting to the support and discard/recycle same. The user would then remove the foil cover from the new/filled bottle, attach the new feeding station to the bottle opening, and mount the new bottle to the receiving portion mounted to the support.
Also contemplated is a kit comprising a number (such as, a “six pack”) of pre-filled disposable bottles/feeding stations and disposable glove(s) advantageously, although not necessarily, matching in number the bottles in the kit. As such, a user would have, at hand for each replacement/refilling operation, a fresh glove to maintain proper and desired sanitation during a corresponding replacement operation, and which could be discarded/recycled along with the spent feed reservoir.
The above disposable feature assures the health and well-being of the human user and the wild birds attracted to the feeder by maintaining uncompromised cleanliness.
The above, and other objects, features and advantages of the present invention will become apparent from the following description read in conjunction with the accompanying drawings.

Referring now to the figures, and in particular,
In the depicted embodiment, a suitable shape for the cooperative engagement structure is conveniently provided as a triangular opening 5 (female) and a corresponding triangular horizontal outer cross-section (male portion 10a), as best seen in the plan views of
Mounting of male portion 10a to female portion 10b is accomplished by general alignment of male portion 10a with opening 5, subsequent insertion upwards of male portion 10a through the opening 5 and into the receiving space, and relative rotation (approximately 60°) to bring male portion 10a to the position shown in dotted lines in
Turning now to
As in the previous embodiment, to accomplish mounting of bottle 20a with receiving portion 20b, bottle 20a is held in an inverted orientation with bottle opening 21 facing downward and is inserted upward through the opening 25 in receiving portion 20b (the latter positioned as shown in
Advantageously, as depicted in
Referring to the assembled depiction in
It will be understood that the principles described above can be implemented in a wide array of bird feeder designs without departure from the contemplated invention. For example, while the engagement structure of the bottle 20a in the above described embodiment is carried on the portion thereof proximate to the bottle opening 21, such structure can alternatively be disposed at a portion distant from an opening, proximate instead with a base of a bottle of suitable design, as exemplified below.
Referring now to
Receiving portion 30b includes a top 36 and an annular base 37 interconnected by a series of circumferentially spaced bars 38. While not depicted in the figures relating to this embodiment, a structure in accordance with that shown at 20b in
Various embodiment of the invention are contemplated as taking a wide variety of shapes and cooperating structural configurations, without departure from the invention. Two examples of possible arrangements are described below.
Referring now to
Turning now to
It will be apparent that any other structural shape that functions in an analogous manner will be within the contemplated scope of the invention, and that, for example, the bottle need not be conical, but can take a stepped shape, spherical shape received in a matching internal configuration, etc. As shown in
Because each of the reservoirs (bottles) 20a, 31, 42 and 52 in the previously described embodiments is inverted to transfer feed contained therein to a feeding station, and is therefore closed at the end facing upwards when inverted for use, each respective structure readily lends itself to production by inexpensive blow molding techniques and materials.
Also, as mentioned above, while the examples are specifically directed to versions in which the bottles themselves serve as a portion of the engagement mechanism cooperative with the mounting structure, it is also deemed to be within the contemplated scope of the invention to instead configure a structural portion or portions carried on, or assembled to, the bottles, for example, the feeding station, such that it, or they, engage the mounting structure to achieve the removable suspended condition of the general type discussed above.
Having described preferred embodiments of the invention with reference to the accompanying drawings, it is to be understood that the invention is not limited to those precise embodiments, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims.
