Co-pending U.S. application Ser. No. 12/228,108 discloses a unique modular bird feeder system which is slideably mounted on a vertically standing pole. In that system; bird feed is poured through a feed filling funnel into a feed housing tube, both components being configured to slide up and down the pole as a single unit and to be maintained in a lowered position, thus allowing easy access for filling. However, operational issues arise with this feeder as the housing tube is slid vertically along the pole. Upon continued use, the feed in the housing tube contacts and abrasively rubs the surface of the pole, resulting in the pole becoming cut and scratched and causing a buildup of feed residue on the pole's surface. This causes unsightly, unattractive marks on the pole. It also inhibits the smooth movement of the feeder components along the pole. Protection of the pole such that these problems are addressed is a key objective.
In addition, if the assembled bird feeder is removed from the pole and there is feed in the feed housing tube, feed will spill out of the feeder. Thus, removal of an assembled, filled feeder from its pole will result in substantial, irretrievable loss of feed. Eliminating this wasteful loss of feed is an important objective.
The system of the present invention solves the problem of the continuous damaging of the bird feeder pole and the loss of bird feed from the feeder when the filled or partially filled feeder is removed from the pole, by providing a specially designed isolation, protective sheath located within the feed container or feed tube housing and around the pole. The upper end of the sheath is held in place within a channel formed in the feed filling funnel. The lower end of the sheath is held in place within a second channel formed in the bird feed tray on which the feed tube housing rests. This system allows for the removal of an assembled, filled bird feeder from its pole without loss of feed. Upstanding walls within the filling funnel are configured to ensure that feed is poured into the feed tube housing with minimal loss of feed at the pole. The feed filling funnel, feed tube housing, protective sheath, and bird feed tray, are all vertically moveable as a single unit along the pole, without causing damage to or undue feed residue buildup on the pole, while maintaining the integrity of the feed in the feed tube housing. In alternate embodiments, the protective sheath is integrally connected to or formed with other components of the system. The protective sheath concept is also adaptable to other pole mounted containers such as hanging plant pots and similar suspended receptacles.
The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The invention, itself, however, both as to its design, construction and use, together with additional features and advantages thereof, are best understood upon review of the following detailed description with reference to the accompanying drawings.
The container fill and pole protection system of the present invention is configured to be incorporated into a modular bird feeder, comprising elongated vertically standing pole 4, feeder roof 6, bird feed receptacle or feed filling funnel 8, feed container or feed housing tube 10, and upper bird feed tray 12. Lower feed tray 13 is also provided as an option on the bird feeder. Feed filling funnel 8, feed housing tube 10, upper bird feed tray 12, and lower feed tray 13 if included, are vertically slideable as a single unit along pole 4 to a lower position on the pole, thus providing ease of feed filling access to the feed housing tube, as described in further detail in the aforementioned co-pending U.S. application Ser. No. 12/228,108, the subject matter of which is incorporated herein.
The present system modifies feed filling funnel 8 with circumferential, upstanding sleeve type wall 14. Feed filling funnel 8 also has circumferential channel 16 which opens downwardly into feed housing tube 10. Upper bird feed tray 12 has circumferential channel 18 opening upwardly into feed housing tube 10. Isolating or protective sheath 20 is an elongated, tubular component sized to closely surround and encircle pole 4. Upper end 22 of sheath 20 is positioned within channel 16 of feed filling funnel 8 and lower end 24 of the sheath is positioned within channel 18 of upper bird feed tray 12. When so positioned, sheath 20 is maintained in position between feed filling funnel 8 and upper bird feed tray 12, but is also slideable up and down pole 4 along with the other moveable components of the bird feeder 2. That is, feed filling funnel 8, feed tube housing 10, protective sheath 20, upper bird feed tray 12, and lower bird feed tray 13, again if included, are all vertically moveable, as a single unit along pole 4.
When it is desired to fill the bird feeder, the moveable feeder components, i.e. feed filling funnel 8, feed housing tube 10, upper bird feed tray 12, and sheath 20, are unlocked from their bird feeding positions atop pole 4 and are slid down pole 4, as described in application Ser. No. 12/228,108, such that the feed filling funnel is at a convenient height for easy user access. Bird feed 30 is then poured 40 into feed filling funnel 8, where it enters feed housing tube 10. Upstanding walls 14 of feed filling funnel 8 prevent the unwanted entry of feed 30 in areas around pole 4, including in between pole 4 and sheath 20. Sheath 20 itself separates feed 30 from pole 4, also preventing the feed from contacting the surface of the pole, and thus protecting the pole from scratches and other harmful abrasions. By keeping feed from contacting pole 4, sheath 20 also prevents buildup of feed residue on the surface of the pole. After feed housing tube 10 is filled with feed 30, the feeder components are slid up pole 4 to roof 6, where the moveable feeder components are returned to and locked into feeding position on the pole, as described in application Ser. No. 12/228,108.
Thus, by the container fill and pole protection system of the present invention, bird feed 30 is easily and efficiently added, without spillage and loss of feed. Significantly, the bird feeder whose feed housing tube 10 is filled or partially filled with feed, can be removed from pole 4 cleanly and without spillage of feed from the feeder. In addition, sheath 20 prevents feed from impacting and abraiding the surface pole 4 and from causing a feed residue buildup on the pole's surface as the moveable components of the bird feeder are slid up and down the pole. Keeping pole 4 free of cuts, scratches and similar abrasions, and of feed residue, not only preserves the appearance of the pole, but also ensures that the slideable operation of the bird feeder up and down the pole remains unimpeded.
