Description

The invention relates to a collection device for a bird feeder mounted either hanging or supported on a post. Furthermore, the invention relates to an arrangement with a bird feeder mounted supported on a post and a collection device according to the invention, as well as a further arrangement with a hanging bird feeder and a collection device according to the invention. A recurring problem with common bird feeders, especially birdhouses or feeding stations, is that the birdseed spills onto the ground below. This can be caused by the birds themselves, such as pecking too vigorously. Another reason is that rainwater washes the birdseed away, depositing it on the ground beneath the feeder. This spilled food attracts pests like mice, rats, and squirrels, which then try to access the food stored in the feeder.Since these pests are usually good climbers, they can, without suitable measures, climb up an existing support post of a bird feeder propped up on it, or up a tree to which a bird feeder is suspended by means of hangers, and get to the stored bird food. In addition to stealing the food, these pests can also leave behind pathogens that are dangerous to the birds being fed, as well as contaminants such as droppings. The object of the present invention is to provide a collection device for a bird feeder mounted either hanging or supported on a post, which solves the problems identified in the prior art. Furthermore, this object is achieved by the arrangements proposed according to the invention. To solve this problem, the invention has the features of claim 1. Accordingly, a collection device for a bird feeder mounted hanging or supported on a post comprises a base plate with a central through-hole and with a plurality of drainage openings, further a circumferential outer rim that is raised above the top of the base plate, and an inner rim that is raised above the top of the base plate and surrounds the central through-hole, further comprising a retaining adapter that is received at least partially in the central through-hole and rests against an underside of the base plate opposite the top for detachably mounting the collection device on the bird feeder. In the context of the invention, the terms above, below, and above are to be understood in relation to the (ground). A component arranged above another component is therefore positioned further away from the (ground) than the other component. The underside of a component faces the (ground), while the top side of a component faces away from the (ground). The particular advantage of the invention lies in the fact that the collection device provides an effective barrier against pests, thus preventing them from accessing the bird food in the bird feeder. The collection device can be advantageously assembled and disassembled without tools. The numerous drainage openings provided in the base plate ensure effective drainage of rainwater, preventing waterlogging and swelling of the bird food. The raised edges (outer and inner) give the base plate a bowl-shaped base, which allows for the collection of bird food while preventing it from being washed away by rainwater. At the same time, the raised outer edge serves as a support for the birds while feeding.The raised inner rim prevents birdseed from flowing through or falling through the central opening, thus protecting the adapter from contamination. This greatly simplifies cleaning the entire collection device. The base plate is preferably made of plastic, particularly preferably of a sustainable plastic material, for example, a pollutant-free, bio-based, biodegradable, or recycled plastic material. The mounting adapter is also preferably made of such a plastic material. Preferred outer diameters for the base plate are 30 cm for use against rats and 34 cm for use against squirrels. The outer diameter can, of course, vary considerably depending on the application, while maintaining the inventive concept and technical effectiveness. The drainage openings preferably have a width or diameter of just a few millimeters, allowing rainwater to pass through but preventing birdseed from doing so. A suitable clear opening or diameter for the drainage openings is between 1 mm and 4 mm. Preferably, the drainage openings are located near the edge, i.e., close to both the inner and outer edges, and arranged radially and evenly distributed on the base plate in a ring pattern. A particularly advantageous embodiment of the collection device provides for at least two adjacent rows of radially distributed drainage openings arranged in a ring, with the drainage openings of adjacent rows being radially offset from one another. This arrangement ensures particularly effective water drainage. Preferably, the top of the base plate has a slightly convex curve in the area between the rows with drainage openings, whereby the drainage openings are arranged in the lowest area of ​​the top of the base plate. The individual drainage openings preferably have a slightly oval or slightly elongated shape. According to a preferred embodiment of the invention, the retaining adapter is detachably received in the central through-hole by force-fit and / or form-fit. The retaining adapter is detachably connected to the base plate, so that it can be designed to be modularly replaceable and, on the other hand, the collection device can be stored, packaged and transported cost-effectively with reduced storage and packaging dimensions. According to a further development of the invention, the retaining adapter has an annular retaining section that can be inserted into the central through-hole by means of force-fit and / or form-fit. The annular shape of the retaining section ensures that an opening is maintained when the retaining adapter is inserted into the central through-hole of the base plate. Preferably, the base plate on its underside, in a region adjoining the central through-hole, and the retaining arm in the region of an upper outer edge of the retaining section, have corresponding shaped steps or ridges. In this way, the annular retaining section can provide a through-hole whose diameter or clear width is essentially identical to that of the central through-hole of the base plate. The retaining section and the base plate thus form a common through-hole with a nearly constant clear width or diameter. Preferably, the retaining section of the retaining adapter, and especially preferably the retaining adapter as a whole, are made of an elastic material, so that the retaining adapter can be attached to the base plate with a slight press fit. This advantageously creates not only a force-fit and form-fit connection but also a watertight seal. According to a further development of the invention, the holding adapter has at least one holding arm adjoining the holding section and projecting towards the underside of the base plate. The holding arm preferably projects substantially perpendicularly from the underside of the base plate. The holding arm provides a fastening section for a connecting element by means of which the collecting device can be connected to a support post of the bird feeder, or alternatively, the holding arm provides a contact section with which the holding adapter can be placed against and / or supported by the support post. In a further development of the invention, the retaining arm is designed to be elastically spring-loaded. Advantageously, this allows the retaining arm of the mounting adapter to press firmly against the support post of the bird feeder. In a further development of the invention, a fastening strap is attached to the support arm as a connecting element. The fastening strap enables a flexible, detachable connection of the support arm to the support post of the bird feeder. The fastening strap makes it possible to connect the collection device to support posts with different cross-sectional geometries. According to a preferred embodiment of the invention, the fastening strap is designed as a hook-and-loop fastener. The hook-and-loop fastener allows for a stepless and therefore particularly flexible connection of the support arm to the support post of the bird feeder. Depending on a tensile force applied by the user, the hook-and-loop fastener can create a form-fitting and force-locking, yet releasable connection. According to an alternative advantageous embodiment of the invention, the closure strap is made of an elastic material and has a plurality of slot-shaped closure openings at a first end of the strap and a closure projection at a second end of the strap shaped correspondingly to the closure openings, such that when the ends of the strap are overlapped to form a closure, the closure projection engages positively in a closure opening. Depending on a tensile force applied by an operator, this embodiment of the closure strap also makes it possible to create a flexible, positive-locking, and force-locking releasable connection. According to a further development of the invention, the retaining arm has at least one opening for the strap through which the closure strap is guided. The strap opening can be formed, for example, by a slot-shaped opening or by a hook-shaped protrusion of material on the retaining arm. According to an advantageous embodiment of the invention, the holding adapter has a plurality and preferably a total of four radially equally distributed holding arms. According to an alternative embodiment of the invention, the mounting adapter comprises a retaining disc and at least one eye bolt held in a threaded bore in the retaining disc as a connecting element. In intended use, the retaining disc rests against the underside of the base plate, and the eye bolt passes through the central through-hole of the base plate. This embodiment of the invention is preferably intended for mounting the collection device on hanging bird feeders. The eye bolt can be mounted to a suspension device by which the bird feeder is suspended. In this respect, the collection device can be used as a barrier positioned above the bird feeder to prevent pests from climbing down from above. According to a further development of the invention, the retaining disc has a first threaded bore on a first side of the disc and a second threaded bore on an opposite second side of the disc, with an eye screw being held in each of the threaded bores. This further development is advantageous for mounting the collection device between the suspended bird feeder and a support object, for example, a branch or the like, from which the bird feeder is suspended. Advantageously, the collection device is movably suspended, i.e., not taut, which further hinders pests from climbing down. The retaining disc is preferably made of an elastic material, particularly preferably of a sustainable, for example pollutant-free, bio-based, biodegradable or recycled, plastic material. It is also conceivable that, while retaining the inventive idea, the collecting device is held in an analogous manner so that it is movable between a suspended bird feeder and the ground, making it difficult for pests to climb up. Preferably, the base plate has a stepped recess on its underside in an area adjoining the central through-hole, into which the retaining disc of the retaining adapter can engage in a form-fitting manner. Preferably, the retaining disc is received therein by an interference fit. To solve this problem, the invention has the features of dependent claim 13. Accordingly, an arrangement according to the invention comprises a bird feeder mounted on a support post and a collection device according to any one of claims 1 to 10, wherein the support post is passed through the central opening of the base plate of the collection device such that the collection device is arranged below the bird feeder and the upper side of the base plate of the collection device faces the bird feeder, and wherein the retaining adapter of the collection device is detachably connected to the support post. The particular advantage of the invention lies in the fact that the collection device can be mounted on the support post without tools, thus forming an effective barrier against pests climbing the post. Pests cannot access the bird feeder and the birdseed it contains. The collection device, with its numerous drainage openings in the base plate and its raised edges, ensures effective drainage of rainwater and prevents birdseed from being washed onto the ground. This prevents the birdseed from swelling due to rainwater and also prevents birdseed from attracting pests. According to a preferred embodiment of the invention, the support post and the retaining adapter of the collection device are connected to each other by means of a locking band that is placed around the support post and guided in the retaining adapter, either by force or by positive locking. The locking band ensures a flexible and releasable, yet sufficiently secure hold of the collection device on the support post. To solve this problem, the invention has the features of dependent claim 15. Accordingly, an arrangement according to the invention comprises a suspended bird feeder and a collection device according to claim 11 or 12, wherein the retaining disc of the retaining adapter is placed against an underside of the base plate of the collection device and the eye bolt is passed through the central opening of the base plate of the collection device, and a suspension means, in particular a rope and / or wire rope and / or a line and / or chain and / or a hook, by which the bird feeder is suspended, engages in or is passed through an eye of the eye bolt of the retaining adapter (9) of the collection device such that the collection device is held above the bird feeder. The particular advantage of the invention lies in the fact that the collecting device provides an effective barrier against pests climbing down the suspension points to the bird feeder. The collecting device can be movably mounted on or between the suspension points, which further hinders pests from climbing down. At the same time, the collecting device protects the bird feeder below from contamination such as leaves, tree fruit, and the like. Further advantages, features, and details of the invention can be found in the dependent claims and the following description.

The figures show various embodiments of a collecting device 1 according to the invention for a bird feeder mounted hanging or supported on a post. The bird feeder is not depicted figuratively. Bird feeders are, for example, birdhouses or bird feeding columns that are supported on posts standing in the ground or that are suspended by means of hanging devices, for example from a tree branch. The collecting device 1 according to the invention is designed to provide an effective barrier against pests, in particular mice, rats, or squirrels, for such bird feeders, preventing these pests from accessing the bird food in the bird feeder. Additionally, the collecting device 1 according to the invention is designed to catch bird food falling from the bird feeder and to keep it clear of the underlying (ground) soil. A first embodiment of a collecting device 1 according to the invention is shown in Figs. 1, 2, 3, 4, 5, 6, 7, 8 to 9. In this embodiment, the collecting device 1 is provided for forming an arrangement or assembly according to the invention with a bird feeder supported on a post. The collecting device 1 has a circular base plate 2 in which a circular central opening 3 is provided. The base plate 2 is bowl-shaped with an outer rim 6 that is raised or raised relative to the upper surface 5 of the base plate 2, and with an inner rim 7 that is conically raised relative to the upper surface 5 of the base plate 2 and extends all around the central opening 3. This bowl-shaped form of the base plate 2 on the upper surface 5 ensures that birdseed can be collected on the upper surface 5 of the base plate 2, with the raised edges 6, 7 forming a railing that prevents birdseed from falling over the edges 6, 7 onto the ground. To prevent rainwater from accumulating and consequently swelling the birdseed, a large number of drainage openings 4 are provided in the base plate 2. The base plate 2 has two rows of drainage openings 4 arranged in a ring, radially evenly spaced, near the outer edge 6, with the drainage openings 4 of each row being radially offset from one another. Additionally, the base plate 2 has two rows of drainage openings 4 arranged in a ring, radially evenly spaced, near the inner edge 7 of the base plate 2. Here, too, the drainage openings 4 of the adjacent rows are radially offset from one another.The large number of drainage openings 4 ensures effective drainage or outflow of rainwater, whereby the drainage openings 4 are dimensioned in terms of their clear width so that they do not allow passage for bird food. The central opening 3 of the base plate 2 is designed to allow the insertion of a support post for a bird feeder. For attaching the collection device 1 to the support post, the collection device 1 has a retaining adapter 9 held on one of the undersides 8 of the base plate 2 opposite the top 5. The retaining adapter 9 has an annular retaining section 10, which features a step or shoulder on its upper outer edge. The retaining section 10 engages in a correspondingly shaped shoulder or step on the underside 8 of the base plate 2 in a force-fit manner. The retaining adapter 9 is preferably made of an elastic material, allowing the retaining section 10 to be inserted into the stepped recess on the underside 8 of the base plate 2 with a slight press fit. Advantageously, the retaining adapter 9 and the base plate 2 can be detachably and tool-free assembled and disassembled, enabling the collection device 1 according to the invention to be stored, packaged, and transported in a particularly compact manner. Furthermore, this allows the retaining adapter 9 to be designed in various modular and interchangeable versions.The ring shape of the retaining section 10 of the retaining adapter 9 makes it possible to mount the retaining adapter 9 with the base plate 2 in such a way that the central passage opening 3 remains essentially unchanged, i.e. with an essentially constant diameter. A retaining arm 11 is attached to the retaining section 10 of the retaining adapter 9, projecting essentially perpendicularly from the underside 8 of the base plate 2. The retaining arm 11 is curved corresponding to the central opening 3 and has two slot-shaped openings 16 for the strap through which a fastening strap 12, in this embodiment designed as a hook and loop fastener 13, is passed. The hook and loop fastener 13 is a continuously adjustable, flexible, and detachable connecting element by which the collection device 1 can be attached to the support post of the bird feeder. The hook and loop fastener 13 can be guided through the strap openings 16 in a loop shape, as shown in Figs. 7, 8 to 9, so that the two ends of the hook and loop fastener 13 can be exposed on a side opposite the holding arm 11 and can thus be pulled tight by an operator.The hook and loop fastener 13 enables the attachment of the collection device 1 to support posts with different cross-sectional geometries. An alternative second embodiment of a collection device 1 according to the invention is shown in Figs. 10, 11, 12, 13, 14, 15, 16 to 17. The base plate 2 is designed analogously to the base plate 2 of the first embodiment of the collection device 1 according to the invention as shown in Fig. 1. However, the retaining adapter 9 and the closing band 12 are designed differently from those of the first embodiment of the collection device 1 according to the invention as shown in Fig. 1. The retaining adapter 9, as before, has a ring-shaped retaining section 10 with a stepped upper outer edge. Four radially evenly spaced retaining arms 11 are attached to the retaining section 10, each projecting essentially perpendicularly from the underside 8 of the base plate 2. The retaining arms 11 are identical in design and each has a belt feed-through opening 16 formed by a hook-shaped or radially offset projecting web section. The closure strap 12 is guided through the strap openings 16 of the four retaining arms 11, the closure strap 12 being made of an elastic material and having a plurality of slot-shaped closure openings 14 at one end and a closure projection 15 at the other end, shaped to correspond to the closure openings 14. To form a strap closure, the strap ends are overlapped such that the closure projection 15 engages positively in a closure opening 14. The embodiment of the collecting device according to the invention shown in Fig. 10 is also designed for forming an arrangement or assembly of the collecting device 1 with a bird feeder mounted on a support post. As can be seen in Fig. 10, the closing strap 12 can be tightened to such an extent that an opening is formed between the ring-shaped closing strap 12, the cross-section of which is smaller than the central opening 3 of the base plate 2. The four retaining arms 11 of the retaining adapter 9, each offset by 90° from the others, allow the closing strap 12 to be closed with a substantially square ring shape, making this embodiment particularly, but not exclusively, suitable for attaching the collecting device 1 to square support posts. A third embodiment of a collecting device 1 according to the invention is shown in Figures 18, 19, 20, 21, 22 to 23. Here, the collecting device 1 is designed for forming an arrangement or assembly with a suspended bird feeder. The base plate 2 is designed analogously to the embodiments of the collecting device 1 according to the invention shown in Figures 1 and 10. The retaining adapter 9, however, differs from the previous embodiments. The retaining adapter 9 has a circular retaining disc 17, which has a centrally arranged threaded bore on each of its opposing, flat disc sides 20, 21. An eye screw 18.1, 18.2 is screwed into each of the threaded bores. Thus, two eye screws 18.1, 18.2, aligned with each other, project perpendicularly from the retaining disc 17 of the retaining adapter 9. When used as intended, i.e., when the collecting device 1 is arranged or mounted according to the invention with a suspended bird feeder, the retaining disc 17 of the retaining adapter 9 is positioned against the underside 8 of the base plate 2 and arranged concentrically to the central opening 3 of the base plate 2. The first eye bolt 18.1 passes through the central opening 3, with a first eye 19.1 of the first eye bolt 18.1 being held on a surface above the edges 6, 7 and the base plate 2. The second eye bolt 18.2 projects perpendicularly from the underside 8 of the base plate 2. The eyelets 19.1, 19.2 of the two eye screws 18.1, 18.2 serve as attachment points or fasteners for the collection device 1 with suspension means of the suspended bird feeder. For example, the collection device 1 can be suspended above the bird feeder by means of hooks or the like engaging in the eyelets 19.1, 19.2. The invention is not limited to the embodiments of the collection devices 1 shown in the figures. In principle, the individual components can be freely selected within wide limits with regard to their shape, dimensions, material selection, arrangement and positioning relative to one another. According to an alternative embodiment of the invention, not shown in the figures, the retaining adapter 9 of the collecting device 1 has a single eye screw 18 held on a disc side 20, 21 of the retaining disc 17. According to an alternative embodiment of the invention, not shown in the figures, the retaining washer 17 and the at least one eye screw 18 are manufactured in one piece, preferably as a single cast component. It is conceivable that the retaining washer 17 and the at least one eye screw 18 are made of plastic. According to a further embodiment of the invention, not shown in the figures, the retaining adapter 9 of the collecting device 1 has a continuous retaining wall instead of one or more retaining arms 11 and is made of an elastic material. The elastic retaining wall is designed to press against a support post of a bird feeder, preferably in a watertight manner, with a clamping force. Therefore, a closure strap 12 as an additional connecting or retaining element can be omitted. According to a further embodiment of the invention not shown in the figures, the conical ring-shaped inner edge 7 of the base plate 2 is made of an elastic material and projects section by section into the area of ​​the central passage opening 3 so that the inner edge 7 presses against a support post of a bird feeder, preferably watertight, all around with a pressing force. According to a further embodiment of the invention not shown in the figures, the inner edge 7 of the base plate 2, a wall of the base plate 2 enclosing the central passage opening 3 and the retaining adapter 9 of the collecting device 1 are made in one piece and from an elastic material. According to a further embodiment of the invention not shown in the figures, the base plate 2 and the retaining adapter 9 are manufactured in one piece, particularly preferably as a single cast component manufactured in one piece. Preferably, the base plate 2 is cleaned using a scraper shaped similarly to a dough scraper. The scraper is preferably made of plastic. The scraper can be included as an accessory or packaged with the collection device 1. Identical components and component functions are identified by the same reference numerals.
