A LIFTING DEVICE AND METHOD OF USE THEREOF TECHNICAL FIELD

[0001] The present invention relates to a lifting device and method of use thereof for use with a beehive having an upper hive box and a lower hive box.

BACKGROUND

[0002] Modern beehives generally have a multi-storey configuration comprising a bottom board having an entrance for the bees, boxes configured to be stacked atop the bottom board and one another containing frames for brood and honey, and a top cap or outer cover for protecting the hive from the elements.

[0003] Typically, the lowermost box is called "a brood box" and is where the queen lays her eggs. In some instances, there can be more than one brood box. The upper boxes are called "honey supers" and are where the honey is stored. The frames are generally hung parallel to each other in the boxes and typically have a plastic or wax foundation on which the bees draw out a beeswax honeycomb.

[0004] It is generally considered good beekeeping practice to routinely inspect the boxes of a hive to ensure the hive is healthy, free of disease, well-fed and not overcrowded and to determine the status of the queen and rate and nature of brood activity.

[0005] However, a problem in general with hive inspections is that it can be challenging (and potentially dangerous) for beekeepers to support upper hive boxes or honey supers while inspecting lower hive boxes, including the brood box.

[0006] The problem is brought about in part due to the rectangular shape and size of the hives boxes, which makes them awkward to lift and handle, and in part due to the weight of the hive boxes, particularly the upper hive boxes or honey supers. Indeed, the problem is particularly pronounced through the season when the honey supers fill with ever growing volumes of honey.

[0007] Lifting devices such as hoists and cranes exist and are commonly utilized in commercial beekeeping operations where they are used to routinely inspect hundreds of hives. However, such hoists and cranes are costly, awkward to manoeuvre, complicated to operate, bulky to store and generally unsuited for and an unnecessary expense for your average domestic beekeeper who may keep one to three beehives.

[0008] It will be clearly understood that, if a prior art publication is referred to herein, this reference does not constitute an admission that the publication forms part of the common general knowledge in the art in Australia or in any other country.

SUMMARY OF INVENTION

[0009] Embodiments of the present invention provide a lifting device and method of use thereof, which may at least partially address one or more of the problems or deficiencies mentioned above or which may provide the public with a useful or commercial choice.

[0010] With the foregoing in view, the present invention in one form, resides broadly in a lifting device for use with a beehive for lifting an upper hive box relative to a lower hive box, said device including at least one hinge for hingedly connecting the upper hive box relative to the lower hive box so that the upper hive box is pivotable between raised and lowered positions relative to the lower hive box about an axis of the at least one hinge. Optionally, the device may further include a support for supporting the upper hive box, when in the raised position. Optionally, the device may further include a handle for raising and lowering the upper hive box relative to the lower hive box.

[0011] According to a first aspect of the present invention, there is provided a lifting device for use with a beehive for lifting an upper hive box relative to a lower hive box, said device including: a support for supporting the device relative to a support surface; at least one support frame member extending from the support to a first end of the beehive, said at least one support frame member being mountable to the lower hive box at the first end of the beehive; and at least one handle member having a mounting end pivotally mountable to the at least one support frame member and a handle portion extending at least partially towards an opposed second end of the beehive and pivotable between raised and lowered position relative to the lower hive box, said at least one handle member configured to be connectable to the upper hive box for pivoting the upper hive box relative to the lower hive box.

[0012] According to a second aspect of the present invention, there is provided a lifting device for use with a beehive for lifting an upper hive box relative to a lower hive box, said device including: a support for supporting the device relative to a support surface; at least one support frame member extending from the support to a first end of the beehive, said at least one support frame member being mountable to the lower hive box at the first end of the beehive; and at least one handle member having a mounting end pivotally mountable to the at least one support frame member and a handle portion extending beyond an opposed second end of the beehive and pivotable between raised and lowered position relative to the lower hive box, said at least one handle member configured to be connectable to the upper hive box for pivoting the upper hive box relative to the lower hive box.

[0013] According to a third aspect of the present invention, there is provided a support frame assembly for use with a lifting device according to the first or second aspects, said assembly including: a support for supporting the lifting device relative to a support surface; and at least one support frame member extending from the support to a first end of a beehive, said at least one support frame member being mountable to a lower hive box at a first end of a beehive and configured to pivotally mount at least one handle member relative thereto such that the at least one handle member is pivotable between raised and lowered position relative to the lower hive box.

[0014] According to a fourth aspect of the present invention, there is provided a handle member for use with a lifting device according to the first or second aspects, said handle member including: a mounting end pivotally mountable to at least one support frame member of the lifting device; and an opposed handle portion end configured to extend from the mounting end at least partially towards an opposed second end of a beehive and be pivotable between raised and lowered position relative to a lower hive box of the beehive, wherein said handle member is connectable to an upper hive box of the beehive for pivoting the upper hive box relative to the lower hive box

[0015] Advantageously, the present invention provides an easy to use lifting device that may readily be fitted to a beehive in a releasable manner to raise an upper hive box relative to a lower hive box for a hive inspection. Once fitted, the upper hive box may be lifted with relative ease and effort using the class || lever formed by the outwardly extending handle member. Further, and by nature of its construction, the lifting device does not disturb a hive entrance when lifting an upper hive box relative to a lower hive box and therefore does not alarm guard bees located at the entrance of the hive. When a hive inspection is concluded, the device may be readily disassembled from the beehive and fitted to another beehive or stowed.

[0016] As indicated above, the lifting device of the present invention is primarily for use with beehives having at least a lower hive box and an upper hive box stacked atop one another. It will therefore be convenient to describe the lifting device with reference to this example application as a lifting device for a beehive. However, a person skilled in the art will appreciate that the lifting device is capable of broader applications and is applicable for use with any stacked box arrangement.

[0017] As used herein, the term "beehive" may refer to any artificial structure for housing a honey bee nest and including a lower hive box and at least one upper hive box stacked atop the lower hive box.

[0018] A lowermost hive box of a beehive may be referred to as a "brood box" and is where the queen resides and lays her eggs. In some instances, a beehive may include more than one brood box stacked atop one another.

[0019] Upper hive boxes stacked atop the lowermost hive box, or lower hive boxes, may collectively be referred to as "honey supers" and are where honey is stored.

[0020] Each hive box may include an open top end and an opposed open bottom end. The open top and bottom ends are interconnected by a pair of opposed end walls and a pair of opposed sidewalls extending therebetween. The opposed end walls and opposed sidewalls may define a generally rectangular profile shape.

[0021] The opposed end walls of the stacked hive boxes may define a first end and an opposed second end of the beehive. The first end may correspond to a front end of the beehive. The opposed second end may correspond to the rear end of the beehive.

[0022] The opposed sidewalls of the stacked hive boxes may define opposed sides of the beehive.

[0023] Each hive box may include a plurality of frames that are generally hung parallel to one another within the box in a spaced arrangement.

[0024] The bees may build a beeswax honeycomb on each frame in which the brood or honey is stored. In some embodiments, each frame may have a plastic or wax foundation defined thereon and configured for bees to draw out the beeswax honeycomb. As used herein, the term "brood" may include eggs, larvae, bee bread and pupae of bees.

[0025] Accordingly, the frames located in the brood box may typically contain brood and the frames located in the honey supers may contain honey.

[0026] The beehive may generally include a bottom board defining an entrance for the bees and atop of which the lower hive box is stacked.

[0027] Likewise, the beehive may include a top cap or outer cover for placement atop an uppermost hive box for protecting the beehive from the elements.

[0028] In some embodiments, the beehive may further include a hive stand for supporting the beehive atop a support surface.

[0029] The lifting device of the present invention may be of any suitable size, shape and construction and may be formed from any suitable material or materials.

[0030] Generally, the lifting device may be formed from a durable and strong material or materials, such as, e.g., plastic, wood or metal material or materials.

[0031] The lifting device may be of unitary construction or may be formed from two or more lifting device pieces, typically the latter.

[0032] As indicated, the lifting device is capable of raising and lowering an upper hive box relative to a lower hive box, preferably about a single range of movement defined by a single horizontal pivot axis. The range of movement about the single horizontal pivot axis may be about 450, about 50, about 550, about 60, about 650, about 700, about 75, about 800, about 85, about 90°, about 95, about 100, about 1050, about 1100, about 115, about 120, about 125, about 1300, about 135, about 1400, about 145, about 1500, about 155, about 1600, about 165, about 170, about 1750 or about 180. Generally, the lifting device may provide a range of movement of the upper hive box relative to the lower hive box about the single horizontal pivot axis of between about 45 and about 135, preferably about 90.

[0033] The single horizontal pivot axis may be located at any suitable location between the support and the first end of the beehive, preferably at a location near the first end of the beehive, more preferably at least about 20mm from the first end.

[0034] As indicated, the lifting device includes a support for supporting the lifting device relative to a support surface, preferably for stabilising the beehive while the upper hive box is pivoted to a raised position relative to the lower hive box.

[0035] Generally, the support may include an elongate, generally vertically oriented structure. The support may include a pair of opposed ends and an elongate body extending longitudinally therebetween. The opposed ends may include a lower end and an opposed upper end.

[0036] The lower end may be configured to engage with a support surface.

[0037] The opposed upper end may be connectable to the at least one support frame member.

[0038] The elongate body may be of tubular or solid construction, preferably the former.

[0039] The elongate body may be defined by at least one sidewall. The at least one sidewall may be curved such that the elongate body has a substantially circular profile shape, although non-circular profile shapes, such as, e.g., a rectangular shape, are also envisaged.

[0040] The support may be of a fixed height as defined between the opposed ends or may be adjustable, preferably the latter.

[0041] In preferred embodiments, the height of the support may be adjustable by a telescopic arrangement. For example, the support may include multiple telescoping support portions slidable relative to one another between a retracted position and an extended position to thereby adjust a height of the support.

[0042] In such embodiments, the support may further include a retaining mechanism for retaining the support portions at a set support height.

[0043] For example, in some such embodiments, the support portions may be locked relative to one another at a set support height by a locking pin extending through co-aligned holes defined in the sidewalls of the portions. The locking pin may be a conventional locking pin or may be a spring-loaded locking pin.

[0044] In other embodiments, the retaining mechanism may include a first part associated with one of the support portions and second part connectable to the first part and associated with another of the support portions.

[0045] The retaining mechanism may include mateable male and female portions that couple together, such as, e.g., a threaded connection, an interference connection, or a friction fit-type connection.

[0046] In some such embodiments, the first part of the retaining mechanism associated with a sidewall of one of the support portions may include a male formation configured to be inserted into, or coupled with, a female formation of the second part of the retaining mechanism associated with another of the support portions.

[0047] In other embodiments, the retaining mechanism may include a clamping device for clamping the support portions relative to one another, such as, e.g., a quick release clamp assembly.

[0048] In yet other embodiments, the retaining mechanism may include a collar fitted to a receiving end of a first support portion slidably receiving a second support portion and a locking ring pivotally coupled to the collar and through which the second support portion extends therethrough, said locking ring may be pivotable between a release position in which the second portion is axially slidable relative to the first support portion and a locking position in which the locking ring applies an inward force to at least one side of the second support portion to prevent axial movement of the second support portion relative to the first support portion.

[0049] In such embodiments, the retaining mechanism may further include one or more biasing members or mechanisms so that the locking ring is biased to the locking position, and so that movement of the locking ring to the release position works against a force of the biasing member or mechanism. The biasing member or mechanism may include one or more springs, such as, e.g., coil springs.

[0050] The locking ring may further include a release portion configured to be depressed to temporarily pivot the locking ring to the release position, typically against the force of the biasing member or mechanism. The release portion may extend away from the ring and at least partially alongside the collar. In preferred such embodiments, the locking ring may be spring-loaded with a spring extending between the release portion and the collar.

[0051] The locking ring may include a central aperture through which the second support portion extends. In the release position, a plane of the central aperture may extend perpendicular to a longitudinal axis of the support members. Conversely, in the locking position the plane of the central aperture may be angled relative to the longitudinal axis of the support members thereby narrowing the central aperture through which the second support member extends and applying the inward force to at least one side of the second support portion.

[0052] In preferred embodiments, the support may include three telescopic portions including an upper support portion, a middle support portion configured to be telescopically received in a lower end of the upper support portion and a lower support portion configured to be telescopically received in a lower end of the middle support portion. Retaining mechanisms may be associated with the lower ends of the upper and middle support portions for retaining the telescopic portions relative to one another at set height.

[0053] In some embodiments, the support may further include a foot operatively associated with the lower end, or the lower end of a lowermost telescopic portion, for supporting the support relative to a support surface. The foot may be formed from rubber, plastic or metal material or materials.

[0054] The foot may include a flanged lower portion for at least partially stabilising the support relative to the support surface.

[0055] As indicated, the lifting device includes at least one support frame member extending between the support and the first end of the beehive for connecting the support to the beehive and for pivotally coupling with the mounting end of the at least one handle member.

[0056] The at least one support frame member may be of any suitable size, shape and construction.

[0057] Typically, the at least one support frame member may include a pair of opposed ends and an elongate body extending longitudinally therebetween, preferably in a linear orientation.

[0058] The pair of opposed ends may include a first end coupled to, or extending from, the support and an opposed second end mountable to the lower hive box at the first end of the beehive.

[0059] The elongate body may be of a tubular or solid construction, preferably the former.

[0060] The elongate body may be defined by at least one sidewall extending between the opposed ends.

[0061] In some embodiments, the at least one sidewall may be curved such that the elongate body has a substantially circular profile shape.

[0062] In other embodiments, the elongate body may be defined by four sidewalls extending between the opposed ends such that the elongate body has a substantially rectangular profile shape. The four sidewalls may include an upper wall, an opposed lower wall and opposed sidewalls.

[0063] A person skilled in the art will appreciate that the at least one support frame member extends forward of the beehive to space the support from the first or front end of the beehive to at least partially stabilise the beehive relative to the support surface, particularly when an upper hive box is pivoted to the raised position.

[0064] The support frame member may have a length of about 400mm, about 450mm, about 500mm, about 550mm, about 600mm, about 650mm, about 700mm, about 750mm, about

800mm, about 850mm, about 900mm, about 950mm, about 1,000mm, about 1,050mm, about 1,100mm, about 1,150mm, about 1,200mm, about 1,250mm, about 1,300mm, about 1,350mm, about 1,400mm, about 1,450mm, or about 1,500mm or more. Typically, the at least one support frame member may have a length ranging from about 650mm to about 850mm.

[0065] In some embodiments, the at least one support frame member may have an adjustable length, such as, e.g., a telescopic arrangement.

[0066] In other embodiments, the at least one support frame member may have a fixed length.

[0067] The first end of the at least one support frame member may be coupled or joined to the support at or nearthe upper end of the support using conventional welding techniques and/or with one or more mechanical fasteners.

[0068] In some embodiments, the first end of the at least one support frame member may be coupled to the support indirectly using a bracket and/or one or more mechanical fasteners.

[0069] The opposed second end of the at least one support frame member may be mountable to the lower hive box in any suitable way, preferably releasably.

[0070] In some embodiments, the second end may include a plate portion configured to abut against an end or side of the lower hive box with one or more openings defined therein, each opening configured to receive a mechanical fastener therethrough to fasten the plate and the second end of the at least one support frame member to the end or the side of the lower hive box.

[0071] In other embodiments, the support frame member and the lower hive box may be connectable by a connecting mechanism or parts thereof. The connecting mechanism or parts thereof may or may not be of integral formation with each of the support frame member and the lower hive box.

[0072] In some such embodiments, the connecting mechanism may include a first part associated with the second end of the at least one support frame member and a second part connectable to the first part associated with an end or side of the lower hive box.

[0073] The connecting mechanism may include a mateable male and female portions that couple together, such as, e.g., by a threaded connection, an interference connection, a friction fit-type connection or a bayonet-type connection.

[0074] In some such embodiments, the first part of the connecting mechanism associated with, or forming part of, the second end of the at least one support frame member may include a male formation configured to be inserted into, or coupled with, a female formation of the second part of the connecting mechanism associated with, or forming part of, an end or side of the lower hive box.

[0075] Conversely, in other such embodiments, the first part of the connecting mechanism may include a female formation configured to at least partially receive, or be coupled with, a male formation of the second part of the connecting mechanism.

[0076] In other embodiments, the end wall and/or an adjacent sidewall of the lower hive box may include one or more protrusions protruding outwardly therefrom and the second end of the at least one support frame member may include a bracket having one or more corresponding shaped openings defined thereon and configured to fit over the one or more protrusions and connect the at least one support frame member to the lower hive box.

[0077] The bracket may be integrally formed with the second end of the at least one support frame member or may be of separate construction, preferably the latter. Typically, the bracket may be coupled or joined to the support frame member at or near the second end using conventional welding techniques and/or with one or more mechanical fasteners.

[0078] Each protrusion may be of any suitable size, shape and construction.

[0079] Generally, each protrusion may include a shank and an outer enlarged head or other type of retaining end located at a distal end of the shank. The protrusion may include or define a neck portion immediately proximal of the enlarged head or other type of retaining end.

[0080] Likewise, the shaped opening may be of any suitable shape to receive at least the enlarged head or other type of retaining end therethrough and engage about the neck portion.

[0081] Typically, the shaped opening may have an inverted key-hole shape. For example, the shaped opening may include an enlarged lower portion for receiving the enlarged head or other type of retaining end therethrough and a narrower upper portion configured to slide around, and be supported atop, the neck portion of the protrusion.

[0082] In some embodiments, the bracket operatively associated with the second end of the at least one support frame member may be configured to abut against and be coupled to the end wall of the lower hive box. In such embodiments, the protrusions may protrude outwardly from the end wall.

[0083] In other preferred embodiments, the bracket may be a corner bracket configured to at least partially fit about a corner defined between the end wall and an adjacent sidewall of the lower hive box. In such embodiments, the protrusions may protrude outwardly from the end wall and/or the sidewall, preferably the sidewall.

[0084] The corner bracket may have a substantially L-shaped profile shape configured to fit about the corner and may include an end wall abutting portion and a sidewall abutting portion orthogonally angled relative to the end wall abutting portion. The corner bracket may extend longitudinally at least partially along a height of the lower hive box. In some embodiments, the sidewall abutting portion may extend at least partially past a junction between the lower and upper hive boxes to define a handle member mount. This will be described in detail later. The one or more shaped openings may preferably be defined in the sidewall abutting portion of the corner bracket.

[0085] In preferred embodiments, the one or more protrusions may each be in the form of a mechanical fastener having a tip and enlarged head and a shank extending therebetween. The shank may include at least a threaded portion located at or near the tip for being threadingly received in a sidewall or end wall of the lower hive box, preferably sidewall.

[0086] In some embodiments, the lifting device may include more than one support frame member extending from the support and connecting to a lower hive box at the first end of the beehive.

[0087] For example, in preferred such embodiments, the lifting device may include a pair of support frame members extending from the support and connecting to front corners of the lower hive box.

[0088] In some such embodiments, the pair of support frame members may be pivotally coupled to the support at or near the upper end so as to be pivotable about a vertical axis to fit to hive boxes of differing widths. The support frame members may be pivotally coupled to the support in any conventional way known in the art.

[0089] As indicated, the lifting device includes at least one handle member pivotally mountable to the at least one support frame member, connectable to the upper hive box and configured to be pivotable between the raised and lowered positions relative to the lower hive box for raising and lowering the upper hive box.

[0090] The handle portion of the at least one handle member mayw extend from the mounting end at least partially towards the opposed second end of the beehive, preferably beyond the opposed second end of the beehive.

[0091] The at least one handle member may be of any suitable size, shape and construction.

[0092] Generally, the at least one handle member may include a pair of opposed ends and an elongate body extending longitudinally therebetween, preferably in a linear orientation.

[0093] The pair of opposed ends may include the mounting end configured to be pivotally mountable to the at least one support frame member and an opposed outer end defining the handle portion.

[0094] The elongate body may be of tubular or solid construction.

[0095] The elongate body may be defined by at least one sidewall extending between the opposed ends.

[0096] In some embodiments, the at least one sidewall may be curved such that the elongate body has a substantially circular profile shape.

[0097] In other embodiments, the elongate body may be defined by four sidewalls extending between the opposed ends such that the elongate body has a substantially rectangular profile shape. The four sidewalls may include an upper wall, an opposed lower wall and opposed sidewalls.

[0098] The at least one handle member may be of unitary construction or may be formed from two or more handle member pieces joined together, typically the latter.

[0099] A person skilled in the art will appreciate that the handle member functions as a class || lever. Further, the person skilled in the art will appreciate that a length of the at least one handle member inversely corresponds to an amount of effort or force required to pivot an upper hive box to the raised position. As such, a longer handle member will require less effort or force than a shorter handle member to pivot an upper hive box to the raised position.

[00100] The handle member may have a length of about 100mm, about 150mm, about 200mm, about 250mm, about 300mm, about 350mm, about 400mm, about 450mm, about 500mm, about 550mm, about 600mm, about 650mm, about 700mm, about 750mm, about 800mm, about 850mm, about 900mm, about 950mm, about 1,000mm, about 1,050mm, about 1,100mm, about 1,150mm or about 1,200mm or more. Typically, the at least one handle member may have a length ranging from about 100mm to about 1,020mm.

[00101] In some embodiments, the at least one handle member may have an adjustable length, such as, e.g., a telescopic or a sliding arrangement.

[00102] The handle portion of the at least one handle member may be configured for a user to apply an upward or downward force to pivot the handle member and the upper hive box between the raised and lowered positions, respectively.

[00103] In some embodiments, the handle portion may include a grip for assisting a user in gripping and holding the handle portion.

[00104] The grip may be of any suitable size, shape and construction and may be formed from any suitable material or materials.

[00105] For example, in some such embodiments, the grip may include a smoothened and shaped handle portion or may include a handle portion having one or more contours defined therein facilitating the gripping of the handle portion by a user.

[00106] In other such embodiments, the grip may include a rubber or plastic grip fitted at least partially over the outer end and the handle portion.

[00107] The mounting end of the at least one handle member may be pivotally mountable to the at least one support frame member in any suitable way that allows the handle member to pivot about the mounting end and the handle portion to be pivotable between the raised and lowered positions.

[00108] Likewise, the mounting end of the handle member may be mountable to any suitable location along a length of the at least one support frame member, preferably to a location at or near the second end of the at least one support frame member.

[00109] The mounting end of the handle member may be directly or indirectly pivotally mountable to the at least one support frame member, preferably indirectly via a handle member mount.

[00110] The handle member mount may be of any suitable size, shape and construction and may be connectable to the at least one support frame member in any suitable way.

[00111] Typically, the handle member mount may include a bracket connectable to the at least one support frame member, preferably the handle member mount may be the corner bracket operatively associated with the second end of the at least one support frame member and configured to fit about a corner of the lower hive box.

[00112] In some embodiments, the mounting end of the handle member may have a bearing and the handle member mount may include a pivot pin for pinning the bearing of the handle member to the mount.

[00113] In other embodiments, the mounting end of the handle member and the at least one support frame member may be hingedly connectable by at least one hinge or part thereof such that the handle member may be pivotable between the raised and lowered positions, preferably about an axis of the at least one hinge.

[00114] The at least one hinge may be of any suitable size, shape and form. For example, the hinge may be a barrel hinge, a pivot hinge, a flag hinge or a living hinge.

[00115] In such embodiments, the at least one hinge may include a first hinge member defined on one of the mounting end of the handle member and the handle member mount of the at least one support frame member and a second hinge member hingedly connectable to the first hinge member and defined on the other of the mounting end of the handle member and the handle member mount of the at least one support frame member.

[00116] In some such embodiments, the first hinge member may include a hook or clamp defining a shaped groove and the second hinge member may include a pivot pin configured to be at least partially received in the shaped groove to hingedly connect the mounting end of the handle member to the handle member mount of the at least one support frame member.

[00117] In other such embodiments, the first hinge member may include a bush having a central aperture and the second hinge member may include a pivot pin configured to extend at least partially through the central aperture to hingedly connect the mounting end of the handle member to the handle member mount of the at least one support frame member.

[00118] In preferred embodiments, the handle member may be releasably mountable to the at least one support frame member so that the handle member may be readily disassembled from the lifting device when not being used.

[00119] In such embodiments, one of the handle member mount and the mounting end may include a hook defining a shaped groove with an entrance and the other of the handle member mount and the mounting end may include pivot pin configured to slide into the shaped groove via the entrance and define the single horizontal pivot axis about which the handle member may pivot.

[00120] Preferably, the handle member mount may be defined in an upper edge portion of the sidewall abutting portion of the corner bracket operatively associated with the second end of the at least one support frame member. The upper edge portion may define an upward facing hook extending forward of the junction between the upper and lower hive boxes. The hook may define an upward facing entrance in the upper edge portion and a shaped groove extending at least partially towards the second or front end of the beehive.

[00121] Likewise, the mounting end of the at least one handle member may include a flange portion extending downwards from an outer sidewall of the handle member at the mounting end and having a pivot pin extending outwardly therefrom.

[00122] In use, the pivot pin of the mounting end may be configured to be aligned relative to the upward facing entrance of the handle member mount and slid into the shaped groove when the handle member is connected to the upper hive box to define the single horizontal pivot axis about which the handle member (and a connected upper hive box) may pivot relative to the lower hive box.

[00123] As indicated, the at least one handle member is connectable to the upper hive box so that the upper hive box is pivotable together with the at least one handle member between the raised and lowered positions.

[00124] The at least one handle member may be connectable to the upper hive box in any suitable way, preferably releasably.

[00125] The at least one handle member may be connectable to any suitable location of the upper hive box.

[00126] The at least one handle member may be directly or indirectly connectable to the upper hive box.

[00127] For example, in some embodiments, the at least one handle member may be indirectly connectable to the upper hive box via an upper hive box mount.

[00128] In some such embodiments, the upper hive box mount may include a bracket operatively associated with the at least one handle member and having one or more openings defined thereon each for receiving a mechanical fastener therethrough for fastening the bracket to the upper hive box.

[00129] In other such embodiments, the bracket of the upper hive box mount may include one or more shaped openings configured to fit over one or more protrusions as previously described.

[00130] In other embodiments, the at least one handle member and the upper hive box may be connectable by a connecting mechanism or parts thereof. The connecting mechanism or parts thereof may or may not be of integral formation with each of the at least handle member and the upper hive box.

[00131] The connecting mechanism may include a first part associated with a sidewall of the upper hive box and a second part connectable to the first part associated with an inner sidewall of the at least one handle member. The connecting mechanism may include mateable male and female portions that couple together as previously described.

[00132] In other embodiments, the at least one handle member may include a clamping arrangement configured to clamp about the sidewall of the upper hive box.

[00133] The clamping arrangement may include a pair of opposed clamping members configured to clamp about rear and front corners of a sidewall of the upper hive box. The pair of opposed clamping members may include a first clamping member located at or near the mounting end of the at least one handle member and a second clamping member located at least partially along a length of an inner sidewall of the at least one handle member.

[00134] In some embodiments, the second clamping member may be movably mounted to the inner sidewall of the at least one handle member to move the second clamping member towards and apart from the first clamping member to adjust a clamping force applied to the upper hive box positioned therebetween.

[00135] The second clamping member may be movably mounted to the inner sidewall in any suitably way.

[00136] For example, in some such embodiments, the inner sidewall of the at least one handle member may include a number of openings defined thereon and spaced along a length of the inner sidewall and the second clamping member may include one or more pegs or protrusions for being inserted into a corresponding opening.

[00137] In other such embodiments, the inner sidewall of the at least one handle may include a rail or track extending at least partially along the length of the inner sidewall and the second clamping member may be slidably mounted to the rail or track and be configured to be slidably moveable relative thereto.

[00138] In other embodiments, the at least one handle member may further include an actuating mechanism for moving the second clamping member towards and away from the first clamping member. The actuating mechanism may preferably enable a clamping force applied to the upper hive box to be adjusted.

[00139] Any suitable type of mechanism may be used. The actuating mechanism may be manually actuated or by using a drive. Movement may be linear, although non-linear movement, such as, e.g., rotary movement, is also envisaged.

[00140] If manually actuated, the actuating mechanism may include one or more of a lever, a ram, an operable handle, a sliding arrangement, a hinged arrangement or pivoting arrangement for moving the second clamping member relative to the first clamping member.

[00141] If using a drive, the actuating mechanism may include a linear actuator (e.g., a hydraulic or pneumatic ram) or an electric motor for moving the second clamping member relative to the first clamping member.

[00142] The opposed clamping members may be of any suitable size, shape and construction suitably adapted to clamp the upper hive box therebetween.

[00143] Typically, the clamping members may each include a clamping surface configured to clamp about a sidewall of the upper hive box, and preferably abut with an end wall portion immediately adjacent the rear and front corners.

[00144] The first clamping member may be defined by an inwardly extending portion of the mounting end configured to at least partially hook about the front corner of the upper hive box. The first clamping member may be integrally formed with the mounting end.

[00145] In preferred embodiments, the second clamping member may be defined by an inner end of an outer handle member portion configured to be fastened relative to an inner handle member portion to provide a clamping force.

[00146] The inner handle member portion may include the mounting end and an opposed outer end portion. The outer handle member portion may include an inner end portion defining the second clamping member and an opposed outer said handle portion.

[00147] The inner and outer handle member portions may be configured to be fastened together by a latch clamp or the like such that the inner end portion of the outer handle member portion abuts the second end or rear end of the upper hive box and is held in abutment while applying a clamping force against the second end or rear end of the upper hive box.

[00148] In some embodiments, the lifting device may include more than one handle member.

[00149] For example, the lifting device may include a pair of handle members extending forward from and connecting to both opposed sidewalls of the upper hive box. The pair of handle members may pivotally mount to support frame members connected to either side of the lower hive box at the first or front end.

[00150] In some embodiments, the lifting device may further include an upper hive box support for supporting the upper hive box when in the raised position relative to the lower hive box.

[00151] The upper hive box support may be of any suitable size, shape and construction.

[00152] For example, in some embodiments, the upper hive box support may include a protrusion extending upwardly from an upper wall of the at least one support frame member and having a support surface defined thereon for supporting an end wall of the upper hive box when in the raised position.

[00153] In other embodiments, the upper hive box support may include a bracket extending upwardly from the at least one support frame member at a location between the opposed ends. The bracket may include a support surface defined on an upper portion thereof for supporting an end wall of the upper hive box when in the raised position.

[00154] The bracket may be coupled or joined to the support frame member using conventional welding techniques and/or with one or more mechanical fasteners.

[00155] In embodiments in which the lifting device includes a pair of support frame members, upper hive box supports may be provided on one or both of the pair.

[00156] In some embodiments, the lifting device may further include a separating mechanism for separating the upper hive from the lower hive so that it may be raised by the lifting device.

[00157] The separating mechanism may be of any suitable size, shape and construction and may be associated with the lifting device in any suitable, preferably operatively associated with the at least one handle member or one of the upper and lower hive boxes.

[00158] Generally, the separating mechanism may include a pair of separating members configured to be inserted between the upper and lower hive boxes and an actuating mechanism for moving the separating members apart from one another to separate the hive boxes.

[00159] Any suitable type of mechanism may be used. The actuating mechanism may be manually actuated or by using a drive. Movement may be linear, although non-linear movement, such as, e.g., rotary movement, is also envisaged.

[00160] If manually actuated, the actuating mechanism may include one or more of a lever, a ram, an operable handle, a threaded arrangement, a sliding arrangement, a hinged arrangement, a cam arrangement or a pivoting arrangement for moving the separating members apart from one another.

[00161] Typically, the actuating mechanism may include a cam arrangement and at least one handle connected to a cam and configured to move the separating members apart from one another when the handle is moved relative to the cam.

[00162] Advantageously, the separating mechanism may further function as a dampener when the upper hive box is lowered relative to the upper hive box.

[00163] According to a fourth aspect of the present invention, there is provided a method of fitting a lifting device relative to a beehive for lifting an upper hive box relative to a lower hive box of the beehive, said method including: mounting at least one support frame member to the lower hive box at a first end of the beehive; supporting the support frame relative to a support surface with a support extending from the at least one support frame member; pivotally mounting at least one handle member to the at least one support frame member, said at least one handle member having a handle portion end extending beyond an opposed second end of the beehive pivotable between raised and lowered positions relative to the lower hive box; and connecting the at least one handle member to the upper hive box so that the upper hive box pivots together with the handle portion between the raised and lowered positions.

[00164] The method may include one or more features or characteristics of the lifting device as hereinbefore described.

[00165] For example, the mounting may include aligning the shaped openings of the corner bracket of the support frame member relative to the protrusions protruding from the sidewall of the lower hive box. The mounting may further include fitting the shaped openings over the corresponding protrusions.

[00166] The supporting may include positioning the support in an erect position relative to a support surface. The supporting may further include adjusting a height of the support such that the at least one support frame member extends forward from the front end of the lower hive box to the support in a substantially perpendicular orientation relative to the support.

[00167] The pivotally mounting may include aligning the mounting end of the at least one handle member relative to the handle member mount of the at least one support frame member, preferably such that the first clamping member is positioned about a front corner of the upper hive box.

[00168] The connecting may include positioning the outer handle member portion relative to the inner handle member portion such that the second clamping member provided at the inner end of the outer handle member portion abuts with the front end wall of the upper hive box.

[00169] The outer handle member portion may then be fastened relative to the inner handle member portion with a latch clamp or the like so as to provide a clamping force between the first and second clamping members and connect the handle member to the upper hive box.

[00170] According to a fifth aspect of the present invention, there is provided a method of lifting an upper hive box relative to a lower hive box with a lifting device according to the first aspect, said method including: pivoting the handle portion of the at least one handle member of the lifting device to the raised position relative to the lower hive box such that the upper hive box is lifted together with the at least one handle member relative to the lower hive box.

DETAILED DESCRIPTION

[00183] Figures 1 to 5, 6A, 6B, 7A and 7B show a lifting device (100) and parts thereof according to an embodiment of the present invention fitted to a beehive (900; not shown in Figure ) for use in lifting an upper hive box (910; not shown in Figure 5) relative to a lower hive box (920; not shown in Figures 5, 7A and 7B).

[00184] Referring to Figure 1, the lifting device (100) includes a support (110) for supporting the device (100) relative to a support surface; and a pair of support frame members (120) extending from the support (110) to a front end (902) of the beehive (900) and being releasably mountable to a lower hive box (920).

[00185] The device (100) further includes a pair handle members (130) releasably connectable to an upper hive box (910) and having a mounting end (140) pivotally mountable to the support frame members (120). The handle members (130) extend rearward of the beehive (900) to define handle portions (136) that are pivotable between a shown lowered position and a raised position, as shown in Figures 3 and 4, for lifting and pivoting the upper hive box (910) relative to the lower hive box (920).

[00186] The beehive (900) is an artificial structure for housing a honey bee nest. As indicated, the beehive (900) includes a lower hive box (920) and an upper hive box (910) stacked atop the lower hive box (920).

[00187] The lower hive box (920) is commonly referred to as a "brood box" and is where the queen resides and lays her eggs. Some beehives may include more than one brood box.

[00188] The upper hive box (910) is commonly referred to as a "honey super" and is where honey is stored. Again, some beehives may include more than one honey super.

[00189] Each hive box (910, 920) includes an open top end and an opposed open bottom end. The open ends are interconnected by a front end wall (912, 922), an opposed rear end wall (914, 924) and opposed sidewalls (916, 926) to define a generally rectangular profile shape.

[00190] The front end walls (912, 922) correspond to a front end (902) of the beehive (900). The rear end walls (914, 924) correspond to a rear end (904) of the beehive (900). The opposed sidewalls (916, 926) define the sides (906) of the beehive (900).

[00191] The beehive (900) further includes a bottom board defining an entrance (908) for the bees and atop of which the lower hive box (920) is stacked, a hive stand (930) for supporting the beehive (900) atop a support surface, and a top cap (940) for placement atop the upper hive box (910) for protecting the beehive (900) from the elements.

[00192] Referring briefly to Figures 2 to 4, the lifting device (100) enables the upper hive box (910) to be pivoted relative to the lower hive box (920) about a single horizontal pivot axis (P) over a range of movement of about 90 ranging from a lowered position as shown in Figure 2, an intermediate position as shown in Figure 3 and the raised position as shown in Figure 4.

[00193] Referring back to Figure 1, the lifting device (100) is formed from durable and strong material or materials, such as, e.g., plastic, wood or metal material or materials.

[00194] As indicated, the device (100) includes a support (110) for supporting the device (100) relative to a support surface and for stabilising the beehive (900) while the upper hive box (910) is pivoted to the raised position relative to the lower hive box (920).

[00195] The support (110) includes a pair of opposed ends and an elongate body (112) extending longitudinally therebetween. The opposed ends include a lower end (114) and an opposed upper end (116).

[00196] The lower end (114) is configured to engage with a support surface via a foot (150). The foot (150) includes a flanged lower portion (152) for stabilising the support (110) relative to the support surface.

[00197] The opposed upper end (116) is connectable to the pair of support frame members (120) via bracket.

[00198] The support (110) is of tubular construction and includes three telescopic portions (111) slidable relative to one another between a retracted position and an extended position to thereby adjust a height of the support (110).

[00199] Referring to Figure 5, the three telescopic portions (111) include an upper telescopic portion (111A), a middle telescopic portion (111B) and a lower telescopic portion (111C).

[00200] The middle telescopic portion (111B) is configured to be telescopically received in a lower end of the upper telescopic portion (111A) and a lower telescopic portion (111C) is configured to be telescopically received in a lower end of the middle telescopic portion (111B).

[00201] Retaining mechanisms (160) are associated with the lower ends of the upper and middle telescopic portions (111A, 111B) for retaining the telescopic portions (111) relative to one another and the support (110) at a set height.

[00202] The retaining mechanism (160) includes a collar (162) fitted to the lower ends of the upper and middle telescopic portions (111A, 111B) and a locking ring (164) through which the middle and lower telescopic portions (111B, 111C) extend therethrough. Each locking ring (164) is pivotable between a release position in which the middle or lower telescopic portions (111B, 111C) is axially slidable and a locking position in which the locking ring (164) applies an inward force to at least one side of the middle or lower telescopic portions (111B, 111C) to prevent axial movement.

[00203] Each locking ring (164) further includes a release portion (166) configured to be depressed to temporarily pivot the locking ring (164) to the release position. The release portion (166) extends away from the ring (164) and alongside the collar (162). A spring extends between the release portion (166) and the collar (162) to bias the locking ring (164) into the locking position, so that depressing of the release portion (166) to pivot the locking ring (164) to the release position works against a biasing force of the spring.

[00204] Referring back to Figure 1, the pair of support frame members (120) extend between the support (110) and the front end (902) of the beehive (900) for connecting the support (110) to the beehive (900) and for pivotally coupling with the mounting ends (140) of the pair of handle members (130).

[00205] Each support frame member (120) includes a pair of opposed ends and an elongate body (122) extending longitudinally therebetween in a linear orientation.

[00206] The pair of opposed ends include a first end (124) coupled to the support (110) and an opposed second end (126) mountable to the lower hive box (920) at the front end (902) of the beehive (900)

[00207] The elongate body (122) is of tubular construction having a substantially rectangular profile shape.

[00208] As previously indicated, the first ends (124) of the support frame members (120) are coupled to the upper end (116) of the support (110) via bracket.

[00209] Referring to Figure 6A, the opposed second ends (126) each have a corner bracket (170) coupled thereto.

[00210] Referring to Figure 6B, the corner bracket (170) has a substantially L-shaped profile shape configured to fit about the front corners of the lower hive box (920) of the beehive (900). The bracket (170) includes an end wall abutting portion (172) and a sidewall abutting portion (174) orthogonally angled relative to the end wall abutting portion (172).

[00211] As shown, the corner bracket (170) extends at least partially along a height of the lower hive box (920) when connected thereto and partially past a junction between the lower and upper hive boxes (910,920).

[00212] Each bracket (170) includes two shaped openings (176) defined in the sidewall abutting portion (174). Each shaped opening (176) has an inverted key hole shape and configured to be fitted over a protrusion protruding outwardly from the sidewall (926) of the lower hive box (920) to connect the bracket (170) and an associated support frame member (120) to the lower hive box (920).

[00213] Each protrusion has an enlarged outer head, and each shaped opening (176) is configured to fit over the enlarged head and slide about and engage with a proximal neck portion of the protrusion.

[00214] Referring back to Figure 1, the pair of handle members (130) each have a mounting end (140) pivotally mountable to the corner bracket (170) coupled to the second end (126) of an adjacent support frame member (120).

[00215] Each handle member (130) includes a pair of opposed ends and an elongate body (132) extending longitudinally therebetween in a linear orientation.

[00216] The opposed ends include the mounting end (140) and an opposed outer end (134) extending rearwardly of the beehive (900) to define the handle portion (136).

[00217] The elongate body (132) is of tubular construction having a substantially rectangular profile shape.

[00218] Each handle member (130) is formed from two handle member portions (131) in a sliding arrangement relative to one another for connecting to the upper hive box (910). This will be described later.

[00219] The handle portion (136) of each handle member (130) is configured for a user to apply an upward or downward force to pivot the handle member (130) and the upper hive box (910) connected thereto between the raised and lowered positions, respectively.

[00220] Referring again to Figure 6B, the mounting end (140) of each handle member (130) is releasably mountable to the corner bracket (170) by a handle member mount (142) defined by an upper edge portion of the sidewall abutting portion (174) of the bracket (170).

[00221] The handle member mount (142) includes an upward facing hook (143) extending forward of the junction between the upper and lower hive boxes (910,920) and defining an upward facing entrance (144) and a shaped groove (145) extending at least partially rearward therefrom.

[00222] The mounting end (140) of each handle member (130) includes a downwardly extending flange portion (146) having a pivot pin (148) extending outwardly therefrom.

[00223] In use, the pivot pin (148) of the mounting end (140) is configured to be aligned and received in the upward facing entrance (144) and slid into the shaped groove (145) of the handle member mount (142), when the handle member (130) is connected to the upper hive box (910).

[00224] The pivot pin (148) defines a single horizontal pivot axis about which the handle member (130) and a connected upper hive box (910) can pivot relative to the lower hive box (920).

[00225] Referring to Figure 7A, each handle member (130) is connectable to the upper hive box (910) so that the upper hive box (910) is pivotable together with the handle member (130) between the raised and lowered positions.

[00226] Specifically, the two handle member portions (131) forming each handle member (130) are configured to provide a clamping arrangement for clamping about the sidewall (916) of the upper hive box (910).

[00227] The two handle member portions (131) include an inner handle member portion (131A) and a distally located outer handle member portion (131B) extending rearward of the beehive (900). The outer handle member portion (131B) is slidable relative to the inner handle member portion (131A).

[00228] The clamping arrangement includes a first clamping member (182) located at and forming part of the mounting end (140) and configured to at least partially hook about a front corner of the upper hive box (910) and a second clamping member (184) defined by an inner end of the outer handle member portion (131B). The second clamping member (184) is configured to abut against a rear end (914) of the upper hive box (910).

[00229] Referring to Figure 7B, the outer handle member portion (131B) is configured to be fastened relative to the inner handle member portion (131A) with a latch clamp (186) to move the second clamping member (184) towards the first clamping member (182; not shown) and apply a clamping force against the upper hive box (910) received therebetween.

[00230] Referring briefly to Figure 3, the lifting device (100) further includes upper hive box supports (190) extending upwardly from each support frame member (120) for supporting the upper hive box (910) when in the raised position as shown in Figures 4 and 6A.

[00231] Each upper hive box support (190) includes a bracket (192) extending upwardly from a support frame member (120) at a location between the opposed ends. The bracket (192) include a support surface (194) defined on an upper portion thereof for supporting a front end wall (912) of the upper hive box (910) when in the raised position.
