Description

AUXILIARY DEVICE FOR MOVING SINGLE OR SEVERAL BEEHIVE FRAMES

Technisches GebietTechnical area

The invention relates to an auxiliary device for moving one or more frames of a beehive in the form of a magazine hive essentially parallel to the installation surface of the beehive, comprising a frame storage rack and at least one frame displacement element.

Stand der TechnikState of the art

In particular, the full honeycombs of common magazine hives can be very heavy, which is why manipulating them by hand by lifting them away is a problem. There are already devices for magazine hives in the prior art so that they do not have to be lifted away, but the individual frames are shifted laterally. In many cases the problem has been solved with guide rails which are permanently attached to the beehives. In addition, in these cases a special bag shape is often required to attach the rails.

described. These known pull-out devices in the area of the frames have the disadvantage that they are complicated and therefore expensive to construct and have to be firmly connected to the individual hives. Since a beekeeper usually owns a large number of hives, he has to acquire a corresponding number of devices or even special hives together with the devices, which in most cases is uneconomical. Another problem is that the bees stick the devices that are permanently fixed to the hives, so that after a short time they no longer function properly and have to be cleaned at great expense. For these reasons, the devices mentioned have not been able to establish themselves on the market.

There are also devices which hold the frames by packing them with side pressure and lift them with a motor or a crank, as described for example in DE 8902874 U1. The disadvantage here are also the higher costs and the susceptibility to errors. A motor also requires a power supply.

Darstellung der ErfindungPresentation of the invention

The object of the present invention is to eliminate the above-mentioned disadvantages and to create a mobile auxiliary device for moving individual frames of a magazine hive, which is easy to handle and can easily be transported from one hive to the next. The device should be able to be assembled and removed quickly, so that only a single device is necessary even with a large number of existing hives.

According to the invention, this object is achieved in that the frame storage rack and the frame displacement element are designed as separate components, the frame storage frame being positionable on at least one of the sides of a beehive and having sliding surfaces extending essentially in the plane of the frame to be displaced in the direction of displacement, and wherein each frame sliding element has at least two interconnected rollers or sliding elements and comprises at least two connecting elements, for example in the form of receptacles, which can be brought into engagement with connection positions fixedly mounted on the frame, for example in the form of projections, when the frame sliding elements are positioned, and wherein the frame displacement element, after the connecting elements have been connected to the connecting positions, can be brought into an operating position by a pivoting movement, in which the frame to be lifted on the roller len or sliding elements is stored and can be moved with little effort on the frame storage rack. The frame sliding element enables the individual frames or several frames to be moved easily onto the frame storage rack and back again. For this purpose, the frame storage rack is placed around the side or on one of the sides next to a magazine loot. Thereafter, the connecting elements of the respective frame displacement elements are brought into engagement with the connecting positions and pivoted into the operating position by a pivoting movement, possibly together with a slight lifting of the frame to be removed. As a result, the frame then rests on the rollers or sliding elements and can simply be pushed in the direction of the frame storage rack. In a particularly simple variant, the rollers or the sliding elements can be guided along the upper edges of the side walls of the frame below for part of the displacement path, so that the frame storage rack only has to be positioned behind the hive. In an alternative embodiment, the frame storage rack can also be positioned with the sliding surfaces on the side of the hive and the rollers or sliding elements can only be guided directly on the frame storage rack. In the operating position, the rollers or the sliding elements of the frame displacement element create a spacing between the frame to be displaced and the frame below, which minimizes the risk of the bees being squeezed in the gap when moving. This is not the case with many prior art devices with permanently mounted running rails.

Another preferred feature is that each frame sliding element is adjustable in length, for example by means of a telescopic connection, and can be fixed in different lengths so that the frame sliding element can be adapted to different frame shapes. There are a large number of magazine hives with different widths and heights and with different numbers of frames on the market. So that the frame displacement element can be adapted to different lengths or widths of magazine bags, it is provided that its length can be adjusted. This can be implemented, for example, in that it consists of two parts pushed into one another, which can be fixed in different positions relative to one another by means of a clamp connection. The distance only needs to be set and fixed the first time it is used, after which the frame sliding element can be used quickly on all frames of the same construction.

According to a further preferred feature, it is provided that the rollers or sliding elements are arranged on a frame displacement element at one end of a leg of a two-sided lever pivotable about a pivot point, a handle for the user being arranged at the end of the other leg. Due to the lever arm designed as a handle, the pivoting movement for lifting the frame into the operating position can be carried out with particularly little effort.

It is also a preferred feature that the pivot point is formed by the connecting element which is in engagement with the connecting position. This allows a particularly simple construction of the frame displacement element. It thus comprises only two rollers or sliding elements, which are each arranged on one leg of an associated lever, and a handle which connects the other two legs of the two levers to one another. At the fulcrum of the lever is the connecting element, for example designed as a hook-shaped recess, which is brought into engagement with the connecting position on the frame, for example a pin, which serves as a projection, when the frame displacement element is positioned. As a result, the connecting element serves, on the one hand, to connect to the frame and, on the other hand, as a joint for the lever by means of which the frame is lifted into the operating position.

According to a possible embodiment of the invention, it is also a preferred feature that a spacer element is provided to secure the operating position of the frame sliding element. This is particularly advantageous in those embodiments in which the frame storage rack is placed behind the hive. Since the frame sliding element is not levered under the frame here, it would fold back into its starting position when released. In order to prevent this, a spacer element is provided which can be designed, for example, as a pin that is placed between the frame wall and the handle. The position of the frame displacement element in the operating position is thus secured and folding back into the starting position is avoided.

According to an alternative embodiment of the invention, it is a preferred feature that, in order to secure the operating position of the frame displacement element, the bilateral lever can be pivoted beyond its dead center and is then held in the operating position via a stop. This is particularly preferred in the variant with sliding surfaces of the frame storage rack that are laterally adjacent to the hive. When the frame displacement elements are pivoted into the operating position, the lever is moved beyond its dead center, whereby it is automatically pressed against an end stop by the weight of the frame, which secures the operating position. In order to move the frame sliding element back into the starting position, the lever must be swiveled past the dead center again.

With regard to the frame storage rack, according to a possible preferred embodiment, it is provided that it comprises at least one, preferably several modular individual elements, which can be arranged laterally next to one of the sides of a beehive at the level of the frame to be moved, and that if necessary on the opposite side of the one below Frame projection elements, for example in the form of angles fastened to the frame, are arranged for placing the frame displacement element. In this variant, the frame sliding elements are placed on the one hand over the fixed bracket and on the other hand over the frame storage frame on the front and back of the hive and then pivoted into the operating position by performing the pivoting movement, whereby the frame is raised. When moving onto the frame storage rack, the rollers or sliding elements of the front frame displacement element are then largely guided on the upper edge of the frame side wall below. In order to be adaptable to different heights, several modular individual elements of the frame storage rack can also be stacked on top of one another and optionally connected to one another.

According to a further embodiment, it is provided that the frame storage rack is adjustable in its width and height in order to be adaptable to different dimensions of beehives. As mentioned above, there are magazine hives in different sizes, so the width and height of the frame storage rack must also be adjusted. The width and height can be adjusted using various known methods.

In a preferred embodiment, it is therefore provided that the frame storage rack comprises two sliding surfaces which are connected to one another by means of at least one scissor joint, whereby an adjustment of the width of the frame storage rack is possible, and that the frame storage rack has supports that can be displaced relative to the sliding surfaces for adjusting the height, which can be fixed in different positions, for example by means of a perforated grid. Other variants, such as plug connections with predefined heights or spindle drives for adjusting the width and height, are also possible. The variant with a connected scissor joint also enables the entire auxiliary device to be transported in a very space-saving manner. The sliding surfaces of the frame storage rack can be designed with a coating with a low coefficient of friction, with rollers, with flange rollers or as a conveyor belt. The same also applies to the rollers and sliding elements. These can also be designed in a wide variety of ways, such as flanged rollers, chains, fillet wheels, runners, etc.

Finally, another preferred feature is that a projection is formed on the frame storage rack and / or on the frame displacement element, which serves as an end stop for the displacement path, so that the frame (s) to be displaced is / are secured against falling. Such a projection can be produced, for example, by lateral projections on the frame storage frame, which come into engagement with corresponding opposing stop surfaces on the frame displacement element when the frame reaches the maximum displacement position.

Weg(e) zur Ausführung der ErfindungWay (s) for carrying out the invention

In Fig. 1, a magazine loot is shown schematically in side view. The magazine hive comprises a hive bottom 18, a brood chamber frame 1 and a honey frame 2 arranged above it. Usually, two or three honey frames 2 can also be arranged, but only one is shown for the sake of simplicity. The magazine loot is set up on a support surface 14. Behind the magazine hive, a frame storage rack 3 is shown on the installation surface 14.

A frame displacement element 4 is placed on the rear side of the upper frame 2. The frame displacement element 4 comprises two bilateral levers 10 which are connected to one another via a handle 12. The connecting elements 6 are peg-shaped projections attached to each lever, these projections being placed on the axis of rotation of the lever 10. The length of the handle 12 can be adjusted, so that the frame displacement element 4 can be adapted to beehives of different widths. The handle 12 is located at one end of a leg 11 of the two-sided lever 10. At the end of the other leg 9 there is a roller 7. Not shown is a connection position fixedly mounted on the frame, here in the form of a hook-shaped projection into which in the inserted state, the connecting elements 6 engage. It goes without saying for the average person skilled in the art that the connection position on the frame can of course also be arranged as a projection and the connecting element 6 as an opposite recess on the frame displacement element 4, as is also the case with an embodiment described below.

In order to place or remove this frame displacement element 4, it is hooked into the relevant connection position on the frame with the connection element 6 and a downward pivoting movement is carried out via the handle 12. The rollers 7 are supported on the sliding surfaces 5 on the frame storage rack 3 and the frame 2 is raised by the pivoting movement.

As a result, the operating position as shown in FIG. 2 is reached. The frame 2 now mounted on the rollers 7 of the frame displacement element 4 can now be pushed backwards onto the sliding surfaces 5 of the frame storage rack 3 with very little effort. On the front of the frame, in the example shown, a very simple frame displacement element 4 connected to the frame is shown, which is guided with its rollers 7 on the upper edges of the frame 1 below when it is moved. If the same frame displacement element 4 with two-sided lever 10 is to be used on the front as on the rear, then corresponding projections, for example in the form of fixed angles or wedges, can be provided on the lower frame 1 on the front wall, on which the rollers are 7 of the corresponding frame sliding element can be supported. So that the frame shifting element 4 pivoted into the operating position cannot fold back into the starting position, a spacer element 13 is provided which is inserted between the handle 12 and the rear frame wall and secures the frame shifting element 4 in the operating position.

Fig. 3 shows schematically a possible embodiment of a frame storage rack 3, which is arranged on a beehive. The frame storage rack 3 comprises two sliding surfaces 5 which are connected to supports 16 which are set up on a mounting surface 14. The supports are displaceable relative to the sliding surfaces 5 and can be fixed in different positions, as a result of which the sliding surfaces 5 can be adjusted in height. To adjust the width of the frame mounting rack 3, the two sliding surfaces 5 are connected to one another by means of a scissor joint 15. This scissors joint 15 can also be fixed in its position.

4 and 5 show embodiments of frame displacement elements 4 which are optimally suitable for use with the embodiment of the frame storage rack 3 from FIG. In the variant according to FIG. 4, the two rollers 7 of a frame displacement element 4 are not arranged on the front and back of the frame 2, but rather on the side walls of the frame 2 . The second roller is connected to the first roller and is supported by a further pivot point. By pressing down the second leg 11 of the two-sided lever 10 over the handle 12, the frame 2 is lifted and heaved onto the rollers 7. The lever 10 is moved beyond its dead center and the operating position is secured by a stop 17. To lower the frame, the lever 10 is again moved beyond its dead center in the other direction.

In FIG. 5, an embodiment variant is shown which is constructed similarly to that from FIGS. 1 and 2. Instead of a connection via an axle, the bilateral levers 10 of this embodiment are, however, only connected via the handle 12. Hook-shaped recesses, which can be brought into engagement with corresponding connection positions 8 in the form of pins fastened to the frame, serve as connecting elements 6. When these frame displacement elements 4 are hooked in and pivoted, the connecting element 6, together with the connecting position 8, serves as a joint and forms the pivot point for the lever 10. Here, too, the lever can be moved past its dead center and the operating position is secured by the stop of the handle 12. As can also be seen in FIG. 5, the storage of the upper frame 2 on the frame displacement element 4 in the operating position between the two

frames

1, 2 results in a gap which minimizes the risk of injury to the bees when moving, which is the case with rail systems with a very narrow gap is not given. Furthermore, the sliding surfaces 5 of the frame storage rack 3 can be manufactured in such a way that, through their thickness, they laterally cover the resulting gap and thus prevent the bees from escaping at these points.
