An insulating partition device (17) for hives with removable panel elements, said device comprising a cardboard panel coated with a coating reflecting infrared radiation.

Description

Insulating partition device for a hive with removable panel elements

The invention relates to an insulating partition device for a hive with removable panel elements.

Modern hives include a hive body into which various panel elements can be inserted. These panel elements can be suspended, in particular in the case of vertical hives with frames, or even rest horizontally, in particular in the case of horizontal hives with bars. Examples include the Dadant, Langstroth, Vornot, de la Warré, De Layens, Zander hives and Top-Bar bar hives.

Among the elements of the panels, mention may be made of frames, for example a Dadant frame or the like, hive bottoms, or even insulating partition devices.

Insulating partition devices can help maintain a temperature suitable for bees. These devices may include a polystyrene panel received in a frame or a wooden panel.

Insulating partition devices, known as PIHP (for "High Performance Insulating Partition") can include a reflective bubble insulator, in fact an aluminized bubble film, enveloping a wooden frame. Reflective insulation can reflect infrared radiation from bees.

By having two partition devices on either side of the area occupied by the bees, we can limit heat loss especially during winter.

There is a need for partition devices for simpler storage and mounting.

An insulating partition device for beehives with removable panel elements is proposed, said device comprising a cardboard panel covered with a coating reflecting infrared radiation.

The proposed partitioning device may be cheaper than existing partitioning devices, due to the low cost of cardboard, thus making it possible to limit the logistical constraints for supply and storage.

In addition, the use of cardboard, a material that is easier to handle than wood and polystyrene, can possibly make it possible to create a frameless partition device, so that storage before assembly will be simpler than with partition devices. with aluminized bubble film.

The cardboard can be corrugated, single layer or double layer for example, or not.

Advantageously, the insulating partition device can be composed solely of cardboard covered with a coating reflecting infrared radiation, that is to say that this device is produced from only one or more blanks of cardboard covered with a coating reflecting infrared radiation.

For example, the partition device may include a rectangular bottom to which are articulated, on two opposite sides, flaps raised relative to this bottom, extending over a thickness of the order of the thickness of a frame. These flaps can be kept upright relative to the bottom by bonding tabs, secondary flaps, or the like.

The invention is in no way limited to partition devices made only of cardboard covered with a coating reflecting infrared radiation.

Alternatively, the partition device can for example comprise a frame, for example made of wood.

The partitioning device may for example further comprise a rectangular cardboard panel covered with a coating reflecting infrared radiation, this panel being stapled to this frame.

A frame defines a recess.

In one embodiment, a strip (with advantageously suitable fold lines, corresponding to the thickness of the frame) of cardboard covered with a coating reflecting infrared radiation can be wrapped around a frame. of the frame on one side and the other.

In another embodiment, provision may be made to staple directly to a frame two rectangular cardboard panels covered with a coating reflecting infrared radiation, each of these panels being stapled to one side of the frame so as to cover the recess of the frame on one side and the other.

The partition device can thus comprise a frame and at least one rectangular panel of cardboard covered with a coating reflecting infrared radiation, this rectangular panel closing the recess defined by the frame.

Advantageously, the partition device can be produced from a single cardboard blank covered with a coating reflecting infrared radiation.

By "reflecting infrared radiation" is meant a reflectance in the infrared spectrum (700 nm - 5 mm) greater than 60%, advantageously between 80% and 100%.

The coating reflecting infrared radiation may for example comprise a layer of a material whose reflectance in the infrared spectrum (700 nm - 5 mm) greater than 60%, advantageously between 80% and 100%.

This material can be metallic or not.

This material can for example essentially comprise (that is to say more than 80% by mass relative to the mass of the coating) of the metal.

This metal can for example include aluminum, silver, gold, copper, and / or other.

This metal may or may not be alloyed.

This metal may for example essentially comprise (that is to say more than 80% by mass relative to the mass of the metal) of aluminum.

This metal can for example essentially comprise (that is to say more than 80% by mass relative to the mass of the metal) of silver.

This metal may for example essentially comprise (that is to say more than 80% by mass relative to the mass of the metal) of gold.

This metal can for example essentially comprise (that is to say more than 80% by mass relative to the mass of the metal) of copper.

The coating may comprise, in addition to the layer of material whose reflectance in the infrared spectrum (700 nm - 5 mm) greater than 60%, one or more additional layers, for example a layer ensuring adhesion to the cardboard.

In an advantageous embodiment, the coating reflecting infrared radiation can comprise a polyester film, for example a PET film coating (for “polyethylene terephthalate”), advantageously a PET film coating.

The thickness of this polyester film can be a few μm, for example 12 μm.

The covering can for example be assembled to corrugated cardboard by lamination, by laminating the metallized layer. One can also provide a printing on polyester side in offset, rotogravure, flexography, or other, with suitable products.

It is further proposed a set of at least one, and advantageously a single, blank of cardboard covered with a coating reflecting infrared radiation, this at least one blank being arranged to form, after volume setting, a partition device. insulating material for hives with removable panel elements.

This assembly can define tenon elements arranged and arranged so as to form tenons after volume setting for the suspension of the insulating partition device.

Advantageously, this assembly can comprise a single blank.

Advantageously, this blank may include two rectangular panels, articulated to a central portion by two fold lines opposite to each other.

This central portion can extend between the fold lines over a width on the order of the thickness of a hive frame.

The blank may further define locking means for holding the panels parallel or substantially parallel to each other, for example a recess system - tongue, a tongue or a hinged flap (e) at the edge of one of the panels opposite to the fold line articulating this panel to the central portion, and secured, for example by gluing or the like, to the other panel.

In one embodiment, the blank defines elements capable of forming, after volume setting, two studs extending in a direction having a component parallel to the direction of the fold lines articulating the central portion with the panels. These tenons can be used to suspend the partition device.

For example, these tenons can extend from two respective lateral ends of the central part.

The cardboard covered with a coating reflecting infrared radiation can be obtained by hot depositing the coating reflecting the infrared radiation on an offset sheet, then by sticking this sheet to the cardboard, for example on corrugated cardboard.

The hive body may or may not have one or more spacer racks. These racks can be located at a distance from the bottom of the hive body, for example a few tens of centimeters from this bottom, and extend longitudinally in a direction normal to the normal of the plane of the bottom.

A hive with removable panel elements is also proposed, comprising an insulating partition device as described above.

Examples include the Dadant, Langstroth, Vornot, de la Warré, De Layens, Zander hives and Top-Bar bar hives.

Among the elements of the panels, mention may be made of frames, for example a Dadant frame or the like, hive bottoms, or even insulating partition devices.

It is further proposed to use an insulating partition device as described above in a hive with removable panel elements.

The invention will be better understood with reference to the figures, which are given by way of example and not limiting.

FIG. 1 shows a hive with an example of a partition device according to an embodiment of the invention.

Figure 2 is a perspective view of the example partition device of Figure 1.

FIG. 3 is another perspective view of the example of a partition device in FIG. 1.

FIG. 4 shows a blank making it possible to obtain, after volume setting, the example of the partition device of FIG. 1.

Identical or similar references may be used from one figure to another to designate identical or similar elements.

The figures being relating to the same embodiment, they can be commented on simultaneously.

Referring to Figure 1, a hive 1 includes a hive body 10, an inlet 2, a feed plan 3, a riser 4, a frame cover 5, and a roof 6.

The hive body 10 comprises a rectangular bottom 11 and four walls erected with respect to the bottom 12, 13, 14, 15. On the walls 12, 14, opposite to each other are fixed two respective racks (not visible in FIG. 1), and panel elements 16, 17 can be inserted into the hive body 10. These panel elements 16, 17 comprise studs resting on the racks, in a manner known per se, so that these elements 16, 17 are suspended.

The panel elements 16 are wooden frames, of the type known from the prior art, for example Dadant frames.

The panel elements 17 are insulating partition devices. Two of these devices 17 are inserted into the hive body, defining a living space for the bees between these devices 17.

Each partition 17 is produced from a blank cut from a sheet of corrugated cardboard covered with silver-colored PET lamination.

With reference to FIG. 4, the blank 20 comprises two rectangular panels 21, 22, articulated to a rectangular central portion 23 by two respective fold lines 24, 25 separated by a distance of a few centimeters, for example 24 millimeters.

Each panel 21, 22 is integral with two tenon elements 26,

28, 27, 29 lateral and adjoining the rectangular central portion 23.

Each tenon element 26, 28, 27, 29 is articulated to this rectangular central portion 23 by the corresponding fold line 24, 25.

The blank 20 further comprises four sealing flaps 30, 31, 32, 33, each sealing flap 30, 31, 32, 33 being articulated to a panel 21, 22, by a lateral fold line 34, 35, 36, 37 not parallel, for example normal, to the fold lines 24, 25.

Cut-outs separate each sealing flap 30, 31, 32, 33 from the tenon element 26, 28, 27, 29 adjacent, so that when these sealing flaps 30, 31, 32, 33 are raised relative to the panels 21, 22, these flaps are also raised relative to the tenon elements 26, 28, 27,

29.

One 22 of the panels has a free edge 38 opposite the fold line 25, while the other 21 of the panels is articulated by a fold line 39 opposite the fold line 24 to an additional central portion 40.

This additional central portion 40 has substantially the same dimensions as the rectangular central portion 23.

This additional central portion 40 set articulated by a fold line 41 opposite the fold line 39 to a flap 42.

This flap 42 has a rectangular shape and three free edges.

In this embodiment, the flap 42 and the panel 22 define locking means.

In alternative embodiments, provision could be made to assemble the elements 22 and 42 by gluing, by staples, or the like.

To return to the illustrated embodiment, the flap 42 defines two tongues 43, 44, cut in the flap on three edges and articulated to the flap 42 by respective fold lines, and the panel 22 defines two tongues 45, 46, cut in the panel 22 on three edges and articulated to the panel 22 by respective fold lines.

The fold lines hinging the tongues 43, 44, 45, 46 to the flap 42 or to the panel 22 are substantially parallel to each other and have substantially identical lengths.

The tongues 43, 44 differ from the tongues 45, 46 by their width, in the direction normal to these fold lines.

The tongues 43, 44, 45, 46 are defined at locations such as when the panels 21, 22 are raised relative to the portion 23, superimposed one on the other, and when the flap 42 is folded under the panel 22, as illustrated in FIG. 2, the tongues 45, 46 can be inserted into the recesses defined by cutouts in the tongues 43, 44, thus ensuring locking of the partition device.

With reference to FIGS. 2 and 3, the sealing flaps 30, 31, 32, 33 can be raised relative to the panels 21, 22.

After setting in volume, the tenon elements 26, 28, 27, 29 form with end portions 47, 48 of the portion 23 of the tenons, intended to rest on a rack so as to suspend the partition.

The sealing flaps may, due to the elasticity of the corrugated cardboard, tend to return to a position in the plane of the respective panels 21, 22, but may then be retained by the walls 12, 14 of the hive body.

It will be noted that once the partition device set in volume and placed in the hive so that the solid panel 21 is oriented towards the brood of the bees, the part of the partition device on the brood side is devoid of protruding cutting, thus allowing to prevent the bees from trying to damage the partitioning devices.
