Description

Retaining run for drug strips

The invention relates to a holder for one or more active substance strips which are attached in front of the entrance hole of a beehive.

An active substance strip which is attached in front of the entrance hole of a beehive as a bee sluice is known from WO2014 / 076036 A1. The rectangular strip consists of a plastic matrix in which an active ingredient is integrated. Two strips are attached to the entrance hole of the beehive in such a way that the bees are forced to enter or leave the beehive through the compartments of the active substance strip. In the case of narrow entrance holes, a single strip could also be sufficient to completely cover the entrance hole. The size of the compartments is such that the bees come into contact with the edge of the compartment when they slip through. The entire surface and the compartments of the active substance strip should be freely accessible in order to ensure the contact of the bees with the active substance strip and the ventilation of the beehive. With the passage through the holes of the active ingredient film, but also with the time spent on an active ingredient strip, the bee takes in active ingredient, which in turn is transferred to other bees through body contact.

It is usually an acaricidal agent that is particularly effective against the Varroa mites, which bees are often infested by bees. Such an active ingredient strip is available, for example, as the product “Polyvar Yellow” for Bayer Austria Ges.m.b.H. in Austria but also approved for other companies of the Bayer group in other countries. "Polyvar Yellow" is a veterinary medicinal product for use in European honey bees against varroosis (caused by Varroa Destructor).

The known type of application of strips of active substance at the entrance of beehives is shown in FIG. Depending on the type of beehive type ps and the dimensions of the entrance hole 52, aids such as thumbtacks, staples, nails 40 and pieces of wood 30 are required to securely fix the active substance strips 20. The active substance strips 20 can be fixed in different ways either from the inside or outside of the beehives 50. In the case of beehives 50 with a wide entrance hole 52, two active substance strips 20 are attached next to one another. At

In beehives with a narrow entrance hole 52, the active substance strips 20 are attached in a cuboid shape in front of the entrance hole 52.

This installation process is tedious and takes a lot of time. Furthermore, the

Covering the strip during attachment can be avoided, which is relatively often not guaranteed. The additional risk of overheating of the colony in the beehive due to insufficient ventilation through the entrance hole closed by the active ingredient strip should also be avoided. The task according to the invention is to find a way to accomplish the application of the active substance strip efficiently and in a time-saving manner. The attachment should be flexible and usable for different widths and heights of the entrance holes of the beehives. Adequate ventilation of the beehives through the entrance hole should be ensured.

The object according to the invention is achieved in a holder for an active substance strip having a longitudinal web, from the ends of which two shorter transverse webs extend at right angles, so that a frame-like structure with three sides is created. On the inside of the frame-like structure there is a fastening gap into which an active substance strip can be inserted. This results in only minimal coverage of the active ingredient strip.

The fastening gap preferably has a width that is less than or equal to the thickness of the active substance strip to be inserted.

The holder can be made of a plastic, wood, metal or composite materials. Of the

Active substance strips can be a plastic matrix containing an acaricidal or other active substance.

The length of the longitudinal web LL (without the attachment region of the transverse webs) is in the range from 10 cm to 40 cm, preferably in the range from 16.3 cm to 16.5 cm. The length of the transverse webs LQ is in the range from 3 cm to 10 cm, preferably in the range from 4 cm to 4.1 cm. The thickness D of the holder in the region of the longitudinal web and the transverse webs is in the range from 0.1 cm to 3 cm, preferably in the range from 0.9 cm to 1.1 cm.

A strip of active ingredient typically has a size in the range from 16 cm x 1.5 cm to 20 cm x 3 cm and a thickness in the range from 0.05 cm to 2 cm. The holes in the drug strip have one

Diameters in the range from 6 mm to 9 mm.

The holder can have side wings on one or both transverse webs on the outside. The side wings widen the bracket laterally and give a leeway when attaching it to differently wide flight holes on beehives. If the holder, including the side wings, is too wide, the side wings can be shortened without affecting the application of the active ingredient strip.

In a preferred embodiment, the longitudinal web has a plurality of ventilation holes. In a variant of the preferred embodiment, the longitudinal web has air slots instead of

Ventilation holes. Since the place of use of the holder is at the entrance hole of a beehive and the entrance hole is covered either by the active substance strip or the holder, the holder can with the active substance strip impair the exchange of air through the entrance hole. In order to keep this impairment as low as possible, there are a large number of ventilation holes or air slots in the longitudinal web of the holder, which are used to ventilate the interior of the beehive. The size of the ventilation holes / air slots, with the maximum diameter / height of 3 mm, is such that bees cannot fit through the ventilation holes or air slots.

The side wings may have the same or less thickness compared to that

Crossbar to which they are attached. The transverse wings preferably have a thickness which is in the range from 20% to 80%, preferably in the range from 25% to 40% of the thickness of the transverse web. In a preferred embodiment, the side wing (s) on one side (e.g. underside) of the holder is flush with the transverse web, while on the other side (e.g. upper side) of the holder there is a step between the side wing 14 and the transverse web 12. The smaller thickness of the side wings saves material and makes it easier to shorten the side wings by cutting or tearing them off. The side wings can also be used to attach the bracket to the beehive. If the side wings have a smaller thickness they can be fastened with less strong fasteners e.g. Rice pins instead of nails.

In order to make it easier to shorten the side wings by tearing them off, breaking off or kinking them, the side wings can have strips of reduced material thickness parallel to the transverse webs, at which they can be shortened. To aid in fastening the holder, the side wings can have one or more fastening holes, preferably one in each segment between the strips of reduced material thickness.

The holder can be made in one piece or composed of several components, the components being connected to one another by suitable connecting means or techniques (e.g. adhesive, gluing, welding). The bracket or the components can be in

Injection molding processes, CNC milling processes, laser cutting processes, water cutting processes, deep drawing processes and / or 3D printing.

It is possible that a single holder with strips of active substance is not sufficient to cover the entire width of an entrance hole. In this case, it is advantageous to attach two holders with strips of active substance next to one another in front of the entrance hole. So that each holder does not have to be attached individually, two holders for active substance strips can be connected to one another at their transverse webs in one embodiment. The two brackets can by suitable

Connecting means are positively connected to one another at their transverse webs. In particular, the first holder can be on the outside of a crosspiece over part or the entire length of the

Cross web have a first connecting means and the second holder on the outside of a cross web have a second connecting means over part or the entire length of the transverse web. In this case, both brackets only have side wings on the non-connected transverse webs.

Suitable connecting means can be a groove on the outside of the crossbar over part or the entire length of the crossbar of the first holder and a T-shaped bung on the outside of the crossbar over part or the entire length of the crossbar of the second holder. The T-shaped bung can be pushed positively into the groove. Other fasteners such as tongue and groove,

Dovetail connections or connection techniques such as gluing or welding are known to those skilled in the art.

There are also beehives with entrance holes of small width, so having a single bracket

A strip of active ingredient is sufficient to cover the entrance hole. Because of the limited number of holes in the strip of active ingredient, bees could jam at the holes, be it from the inside or outside, if many bees want to leave the beehive or enter the beehive at the same time. In this case, the number of holes for entry and exit can be doubled by connecting two holders with active ingredient carriers with their long sides at right angles to each other, so that a structure with a front and top is created that can be attached to the entrance hole. For this purpose, two holders for strips of active substance can be connected to one another at their longitudinal webs. The two holders can be positively connected to one another at their longitudinal webs by suitable connecting means. In particular, the first holder on the

Have a first connecting means on the front side on its longitudinal web in the area of the outer edge over part or the entire length of the longitudinal web and the second holder have a second connecting means on the outside of its longitudinal web over part or the entire length of the longitudinal web.

Analogous to the connection of the transverse webs, suitable connecting means for the longitudinal webs can have a groove in the area of the outer edge over part or the entire length of the longitudinal web of the first

Bracket and a T-shaped bung on the outside of the longitudinal web over part or the entire length of the longitudinal web of the second bracket. The T-shaped bung can be pushed positively into the groove. Other connection means such as tongue and groove, dovetail connections, or connection techniques such as gluing or welding are known to the person skilled in the art.

The holder according to the invention for an active substance strip simplifies and accelerates the

Attachment of active substance strips at the entrance hole of beehives enormous. The holder according to the invention enables a quick adaptation to different dimensions of beehives and entrance holes by simply shortening the side wings. characters

The holder for an active ingredient strip is in two different ways in FIGS

Embodiments 10a and 10b shown. In both embodiments, the holder has a longitudinal web 11, from the ends of which two shorter transverse webs 12 extend at right angles, so that a frame-like structure with three sides is created. The holder 10a, 10b consists of a plastic. The longitudinal web 11 has a plurality of ventilation holes 17 (FIG. 2). On the inside of the frame-like structure, that is to say on the inside of the longitudinal web 11 and the transverse webs 12, there is a fastening gap 13 into which an active substance strip can be inserted (FIGS. 3, 4).

On the outside of one of the transverse webs 12, each holder 10a, 10b in the embodiment shown in the figures has a side wing 14 (FIG. 2). The side wings 14 have a thickness which corresponds to only about a third of the thickness of the corresponding transverse web 12 and are flush with the transverse web on the underside of the holder 10a, 10b, while on the upper side of the holder 10a, 10b there is a step between the side wings 14 and Cross web 12 results. The embodiments of the holder 10a and 10b differ in that the side wings 14 of the second holder 10b are located on the right transverse web 12 when the holder 10b is open to the viewer downwards and in the case of the first holder 10a on the left transverse web 12 (FIGS. 2, 10 ). The side wings 14 are shown in FIGS. 5 and 6 in detail. The side wings 14 have strips of reduced material thickness 15a, 15b, 15c parallel to the transverse webs 12, at which they can be easily bent by the user in order to change the width of the side wings 14 and thus the width of the holder 10a, 10b to the size of the To adapt entrance hole 52 of a beehive 50. In addition, the side wings in each segment between the strips of reduced material thickness 15a, 15b, 15c have a mounting hole 16 through which a nail or thumbtack can be inserted.

7 and 8, a further difference between the embodiments of the holder 10a and 10b becomes clear. The first holder 10a has a groove 24a on the transverse web 12a, which has no side wing 14. The second holder 10b has a T-shaped bung 24b on the transverse web 12b, which does not have a side wing 14. The T-shaped bung 24b and the matching groove 24a extend over the entire length of the transverse web 12b, 12a. The T-shaped bung 24b and the groove 24a are dimensioned such that the T-shaped bung 24b can be pushed into the groove 24a, so that the groove 24a and the T-shaped bung 24b form a positive connection (FIG. 11).

In Figs. 7 and 9 it can be seen that the first holder 10a continues to be on the front of the

Longitudinal web 1 la has a groove 25a in the region of the outer edge over the entire length of the longitudinal web 1 la. The second holder 10b has a T-shaped bung 25b on the outside of its longitudinal web 1 lb over the entire length of the longitudinal web 1 lb. The T-shaped bung 25b and the groove 25a are dimensioned such that the T-shaped bung 25b can be pushed into the groove 25a, so that the groove 25a and the T-shaped bung 25b form a form-fitting connection.

FIGS. 10 to 13 show photos of the described embodiments of the mountings 10a and 10b with the active substance strip 20 inserted.

In FIG. 10, the holders 10a and 10b are not connected and the T-shaped bung 24b, the T-shaped bung 25b and the groove 25a can be seen.

In FIG. 11, the two mountings 10a and 10b are connected to one another with their transverse webs 12a and 12b via the groove 24a and the T-shaped bung 24b.

In Fig. 12 and Fig. 13, the two brackets 10a and 10b are connected to one another with their longitudinal webs 11a and 1bb via the groove 25a and the T-shaped bung 25b. 14 and 15 show photos of a variant 110a and 110b of the mountings 10a and 10b. The variants 110a and 110b differ from the mountings 10a and 10b in particular in that they have air slots 118 in the transverse webs 11a and 111b instead of the ventilation holes 17. Furthermore, there are three fastening holes 116 in different positions in the side wings 114 in each segment between the strips of reduced material thickness, so that there is more flexibility with regard to the positioning of the fastening means during fastening. The T-shaped bung (124b) on the transverse web 112b of the variant of the second holder 110b is partially pushed into the groove in the transverse web 112a of the first holder 110a without active ingredient strips. In the variant of the second holder 110b shown, there is an active substance strip 20.

15 shows an enlarged section of the two variants of the first mountings 110a and the second mount 110b. They are connected to one another with their transverse webs 112a and 112b via the groove in the holder 110a and the T-shaped bung 124b of the holder 110b. 15 shows, in an enlarged view, in particular the air slots 118 of the variant of the second holder 110b.

The active ingredient strip (20) in FIGS. 10 to 15 has a size of 17 cm x 2.2 cm and a thickness of 0.3 cm. In the example shown, the length of the longitudinal web LL (without the attachment area of the transverse webs) is 16.4 cm. The length of the crossbars LQ is 4 cm. The thickness D of the bracket in the area of the

Longitudinal bar and the cross bars is 1 cm.
