Abstract

Bird feeding apparatus 10 comprising a main body 12 that provides access to bird food and a base member 16 having a plurality of shedding faces (18, fig. 2) which are inclined so that a bed of food particles in the main body 12 settling under gravity is shed towards feeding ports 14 located proximal the periphery of the base 16 where each shedding face (18, fig. 2) has at least two mutually inclined substantially flat surfaces (20, fig. 2) that together form a valley (22, fig. 2) the floor (28, fig. 2) of which descends as it approaches the periphery of the base. The shedding faces (18, fig. 2) may include additional side surfaces (24, fig. 2) and slots (34, fig. 2) may be present as drainage channels.

Description

24023 1 5 Bird Feeding Apparatus Bird feeding apparatus typically comprise

a tubular shaped main body used to store bird feed; this body having feed ports located near the lower end. Often a base member engages the lower end of the main body. Typically, this base member supports perches that extend therefrom. The base member may be generally conical in shape or have a centrally upwardly extending plug. It is known for this plug to comprise a pair of shedding faces; each shedding face being formed from a single inclined flat surface or a single surface with a concave recess. The concave surface may have a drainage channel to assist removal of rainwater and the like that would otherwise lead to deterioration of the bird feed.

The use of a concave shedding face improves distribution of feed to the feeding ports and helps avoid dead spots; where food may remain between refilling and so may go bad. Base members with concave shedding faces as described above will, in use, not normally allow water to drain from the faces if the longitudinal axis of the birdfeeder body is inclined at a angle of more than a 10 or so to the vertical; even when such surfaces are provided with a drainage channel.

An aim of the present invention is to provide improved bird feeding apparatus. Further aims of the invention are to provide a base member that more effectively directs bird food to feeding ports and also that more effectively allows rainwater and the like to drain from the base.

In one aspect the invention comprises bird feeding apparatus comprising a main body that provides access to bird food and a base member wherein the base member has a plurality of shedding faces which are inclined to effect shedding of food particles under gravity towards a feeding port or ports located proximal the periphery of the base; characterized in that each shedding face comprises at least two mutually inclined substantially flat surfaces that together form a first valley the floor of which descends as it approaches the periphery of the base.

Each shedding face may comprise a further flat side surface between at least one substantially flat inclined surface and the periphery of the base; preferably, each shedding face comprises P303776GB two further side surfaces; each side surface being located between an inclined substantially net surface and the periphery of the base.

The base and the main body may be substantially circular in cross section, in which case the side surface in plan view is substantially the shape of part of an annulus. Preferably, the side surfaces together form a second valley that is a continuation of the first valley. The floor of the second valley may be substantially horizontal. The second valley may haves a drainage channel that allows water to exit the feeder base via a drainage channel but generally does not permit feed to pass therethrough. Typically the base has two or three shedding surfaces.

The invention will now be described by reference to the following diagramatic illustrations in which: Figure 1 shows a perspective view of a birdfeeder according to the invention; Figure 2 shows a perspective view of a base member of the birdfeeder of Figure 1; Figures 3a, 3b and 3c show a plan and side views respectively of the base member of Figure 2; Figures 4a and 4b show cross sections along the lines X-X and Y-Y respectively of Figure 3a; Figure 5 shows a perspective view of a further embodiment of the invention: Figures 6a, 6b, 6d and 6c show a top view, side views and an underside view respectively of the base member of Figure 5; and Figures 7a and 7b show cross sections along the lines A-A and B-B respectively of Figure 6a.

A first embodiment of the invention will now be described by reference to Figures 1 to 4. A birdfeeder 10 comprises a tubular main body 12 with feeding ports 14 near its lower end and a base member 16 that engages the lower end of main body 12.

Base member l 6 (see Figures 2 and 3) has a pair of shedding faces 18 separated by a ridge 19 extending substantially diametrically across the top of base member 16. Each shedding face 18 comprises four surfaces; two mutually inclined substantially flat surfaces 20 that together form a "first valley" 22 and partly annular shaped side surfaces 24 that together form a "second valley" 26. The floor 28 of the first valley 22 slopes downwardly in its travel from P3()3776GB the centre of the base towards the periphery of the base. The lowest point 30 of floor of the first valley 22 is coterminous with the highest point 30 of the floor 32 of the second valley 26.

The floor 32 of the second valley is preferably substantially horizontal but may also slope downwardly in a direction towards the periphery of the base. Secondary valley 26 has a slot 34 that prevents rainwater accumulating at the bottom of the shedding face by allowing it to drain through a lower frustro-conical portion 38 of the base member 16 to the surroundings.

Rim 36 located between lower frustro-conical base portion 38 and the upper generally cylindrical portion 40 of the base is provided to assist engagement of the base member 16 and the tubular main body 12. Base member 16 is also provided with vertical slots 42 that allow water to drain therethrough to the surroundings. Slots 42 allow rainwater to be discharged via recesses 44 located at the bottom end of the slots and extending below rim 36 into the lower base portion 38 and therefore also extending below the bottom end of the tubular main body 12. Recesses 46 and 48 are provided in the peripheral wall of the base member in order to interface with the rear surface (not shown) of feeding ports 14.

Figures 4a and 4b show cross sections along the lines X-X and Y-Y respectively of Figure 3a.

In this embodiment ridge 19 is horizontal. Floor 32 of the second valley is also horizontal and side surfaces 24 take the form of a partial spiral ramp.

A second embodiment of the invention is shown in Figure 5 to 7. This is similar to the first embodiment described above; the essential difference being that in this embodiment there are no side surfaces, and so no second valley; but just a pair of mutually inclined substantially flat surfaces 120. In this embodiment drainage slot 134 is located in the downwardly facing floor 128 of first valley 122.

There will normally be a shedding face for each feeding port. For example a tubular main body 12 with three feeding ports 14 would be provided with a base member 16 having three shedding faces. This ensures that bird feed is directed specifically towards each feed port.

While it is preferred that the main body and base have a circular shape as viewed from above (see Figures 3a and 6a) other shapes are possible; for example, they may be elliptical, square, pentagonal, hexagonal or rectangular in shape.
