DETAILED DESCRIPTION

[0029] A beehive honey frame according to the present invention is illustrated in FIGS. 2A to 2C. The frame 101 comprises a perimeter framework 102, the perimeter framework 102 having a top bar 102a, a bottom bar 102b and opposed side bars 102c. The perimeter framework 102 is rectangular. The perimeter frame 102 supports a foundation sheet or plate 103 within the perimeter framework on which the bees of a hive build a honey comb. The illustrated frame 101 is a unitary moulded plastic component comprising the perimeter framework 102 and an integral foundation sheet 103 inside the perimeter framework. However, the present invention may consist in a beehive honey frame comprising a perimeter framework 102 without an integrally formed foundation sheet 103.

[0030] The foundation sheet 103 preferably has a honey comb pattern. The illustrated embodiment shows the honeycomb pattern on a portion of the sheet only, however preferably the honeycomb pattern covers the full surface of the sheet 103 on both sides, as known in the art. A plastic foundation sheet is coated with beeswax or other covering such as a sugar coating to encourage bees to build honeycomb on the sheet 103.

[0031] According to the present invention, one or both side faces of the perimeter framework 102 is/are adapted to provide a foundation on which bees build honeycomb. For example, a coating may be provided to the side faces of the perimeter framework, wherein the coating encourages bees to build honeycomb on the side faces of the perimeter framework. The coating may for example be beeswax.

[0032] In the preferred illustrated embodiment, the perimeter framework comprises apertures or depressions 104 in the side faces 105 of the perimeter framework to encourage bees to build honeycomb on the side faces of the perimeter framework. Preferably the perimeter 102 framework has apertures or depressions 104 on both side faces, however apertures or depressions 104 may be provided to one side face of the perimeter framework.

[0033] The apertures or depressions 104 each have a lateral dimension and area similar to or the same as a lateral dimension and area of a typical cell of a honeycomb, to encourage comb production. For example, the apertures or depressions 104 each have substantially the same lateral dimension (e.g. width w in FIG. 3A) as each aperture or depression of the honeycomb pattern formed on the sheet 103. A typical bee honeycomb cell has six sides with a lateral dimension or width of about 5 mm across opposed sides of the cell. A cell may have a lateral dimension of about 4.5 mm to 5.5 mm across opposed sides of the cell. Thus, the apertures or depressions 104 in the side 105 of the perimeter framework preferably each have a lateral dimension or width w of about 4.5 mm to 5.5 mm. For a regular hexagonal shaped aperture, a width across opposed sides of the aperture of 4.5 mm to 5.5 mm corresponds to an area of about 17 to 26 mm.sup.2. The apertures or depressions preferably have six sides, e.g. are approximately hexagonal, to replicate a sixed sided natural bee cell, but may be circular, or have less than six sides or more than six sides. More than five sides are preferred. Where the aperture or depression has five or more sides preferably the aperture or depression is a regular polygon. A circular aperture or depression may have a diameter (lateral dimension) of about 4.5 mm to 6.5 mm, with a corresponding area of about 16 to 32 mm.sup.2, to be about the same size as a cell of a honeycomb.

[0034] The apertures or depressions 104 have a depth 106 in a width direction of the frame 101. The width direction of the frame 101 is indicated by the width dimension W FIG. 2B. The depth (d in FIG. 4A) of the apertures or depressions 104 is preferably approximately equal to the distance from the foundation sheet 103 to the side face 105 of the perimeter framework 102. For a top bar 102a width (W in FIG. 2B) of 35 mm and a foundation plate 103 thickness of 1.8 mm, the depth d of the apertures or depressions 104 in the side face 105 of the top bar 102a will be about 16.6 mm. For a plastic moulded frame 101, preferable the apertures or depressions 104 have a slight taper as shown in FIG. 4B, so that an inner end or base of the depression or aperture 104 is slightly smaller than an outer end of the depression or aperture. The taper assists in manufacture to remove the frame 101 from a mould. The apertures or depressions 104 are preferably deeper than the apertures or depressions 103a formed on the sides of the foundation plate 103. The apertures or depressions 103a formed on the foundation plate may have a depth of about 1 mm to 2 mm. The thickness of the foundation plate is substantially less than the width W of the perimeter framework.

[0035] Preferably the beehive honey frame 101 has the apertures or depressions 104 around a full perimeter of the perimeter framework 102, as shown in FIG. 2A. However, in some embodiments the beehive honey frame 101 may have the apertures or depressions 104 along the side faces of the top bar 102a, or the bottom bar 102b, or one or both side bars 102c. The spacing between adjacent apertures or depressions 104 may be the same as or similar to the spacing between cells in natural honeycomb. The material of the perimeter framework 102 between adjacent apertures or depressions 104 forms strengthening ribs, so that the perimeter framework with apertures or depressions forms a structural member of the beehive honey frame 101 to prevent the beehive honey frame 101 from twisting or bending. In some embodiments, the material between adjacent apertures or depressions has thickness of about 1-2 mm. In the illustrated embodiment, the apertures or depressions 104 have a lateral dimension w of 4.8 mm, and a centre-to-centre spacing with adjacent apertures or depressions arranged side-by-side (s1 in FIG. 3A) of about 6.4 mm, resulting in a material or rib thickness between adjacent apertures or depressions of about 1.4 mm. In the illustrated embodiment, the apertures or depressions 104 in the side faces of the side bars 102c are arranged corner-to-corner, with a centre-to-centre spacing (s2 in FIG. 3A) of about 7.15 mm, resulting in a material or rib thickness between adjacent apertures or depressions of about 1.4 mm. In the illustrated embodiment, the beehive honey frame 101 has a single row of apertures or depressions 104 in the side faces 105 of the perimeter framework 102. The row of apertures provides an array to replicate a portion of a natural honeycomb pattern (i.e. a cellular arrangement). In some embodiments, the beehive honey frame 101 may have more than one row of apertures or depressions in a side face or side faces of the perimeter framework 102.

[0036] Prior to use, bees wax or other foundation coating is preferably applied to the side face or side faces 105 of the perimeter framework 102, to coat inner surfaces of the apertures or depressions 104, to encourage bees to build comb in the apertures or depressions 104 on the side faces 105 of the perimeter framework 102. Preferably the foundation coating is applied to the side faces 105 of the perimeter framework 102 at the same time a foundation coating is applied to the sides of the foundation plate 103.

[0037] Providing comb sized apertures or depressions 104 on the side faces 105 of the perimeter encourage bees to build comb on the side faces of the perimeter framework so that the honey comb covers the side faces of the frame out to an outer perimeter edge 106 of the beehive honey frame 101. This result has two significant benefits. Firstly, hive yield is increased since the productive surface area of a beehive honey frame 101 is increased from being the area of the sides of foundation plate 103 within the perimeter framework 102, to be the area of the sides of the foundation plate 103 and additionally the area of the side faces 105 of the perimeter framework 102. The improved beehive honey frame increases revenue per frame. Secondly, by causing the bees to cover side faces 105 of the perimeter framework 102 with honeycomb, the hive becomes more resistant to small hive beetles. By building honeycomb to the outer edges 106 of the frame 101, bee activity is present at the frame 101 outer edges 106, giving the bees a higher chance of fighting/corralling beetles at the edge of the beehive honey frame 101 or otherwise reducing the chance of beetles travelling further inboard on the beehive honey frame 101.

[0038] The present invention may be used together with other known pest control means, such as traps. In-hive traps are necessarily small and therefore require frequent emptying. The present invention assists in the control of beetles, and therefore if used together with traps reduces the frequency in which traps must be cleaned, and refilled with oil if oil is used.

[0039] The invention may also be said broadly to consist in the parts, elements and features referred to or indicated in the specification of the application, individually or collectively, in any or all combinations of two or more of said parts, elements or features.

[0040] Aspects of the present invention have been described by way of example only and it should be appreciated that modifications and additions may be made thereto without departing from the scope thereof as defined in the appended claims.
