For fixing the spoke plate, the frame has at least one clamping element (8, 9; 108, 208; 20; 21, 209; 24; 12, 309; 221, 409) which applies to both faces of the radius plate. The frame can be divided into several parts which can be linked together in a detachable manner. When this frame is in two parts, they are preferably identical. The clamping elements are shaped with the aim of constituting spacers extending inside the frame and supporting the radius plate.

Description

"Honeycomb frame".

The innovation relates to a frame for honeycombs, each with a pair of elongated longitudinal and transverse struts, and with a device for fastening a honeycomb plate forming the central wall within the frame.

Conventional frames of this type are provided in their final form on two mutually parallel struts, in particular the cross struts, with eyelet holes through which a fine wire is drawn in such a way that a plurality of parallel strands of this wire finally pass through the frame interior. The wax middle wall, which already contains the basic structure of the honeycomb, is then placed on these wire strands. Subsequent heating of the wires, in particular by passing current through them, softens the central wall lying thereon and, during the subsequent cooling, firmly bonds to the wires which thus carry the honeycomb plate. It is understood that with the production of such

It takes a lot of work and time to frame until it is inserted into the floor. Apart from nailing the frame itself and possibly attaching spacer pins, the finished frame must then be perforated and wired, after which the middle walls described above are soldered in. The innovation is based on the task of facilitating and reducing the work of the beekeeper and, above all, of making it easier to attach the coat walls. According to the innovation, this is achieved in that at least one clamping body acting on its two surfaces is provided for fastening the honeycomb plate. In this way, the middle wall only needs to be clamped to the frame, which can be done quickly and in a labor-saving manner. The simplest way to do this is that the frame is designed to be divisible, the frame parts being connectable to one another with the aid of a non-destructively releasable connecting device, and in that a part of the clamping body is arranged on each frame part. The frame can be cheaper if two identically shaped

Frame parts can be connected to form a whole frame with the aid of the connecting device, because in this way the manufacture of the frame can be achieved with a single tool or simplified mechanical equipment.

If the one or more clamping bodies are at least partially formed in one piece with the longitudinal and / or transverse struts of the frame, there is not only the advantage of simplified manufacture of the clamping bodies, but also that they are captively connected to the frame. According to a preferred embodiment, the frame division can take place in such a way that at least one of the longitudinal and transverse struts of the frame is divided parallel to its longitudinal axis in its width, and that preferably at least one of the two strut parts which can be detached from one another each has a holding part of at least one clamping body for the Has honeycomb plate, whereas the associated other holding part is provided on another part of the frame. The insertion of the base plate is facilitated and its fit within the frame is improved when all the struts of the frame are divided and the frame can thus be disassembled into two interconnectable frame parts essentially along a division plane. This in no way precludes the fact that not every frame part can have protrusions protruding beyond the parting plane and fitting into corresponding recesses in the other frame part; in fact, a certain interlocking of the two parts can prove to be advantageous for reasons of stability. However, the frame can also be divided transversely, in particular perpendicularly, to its longitudinal and / or transverse struts, for example at the end of the struts, but preferably in the middle thereof, with two identical ones, with a single tool, precisely when divided vertically through the center or simplified machine equipment produce stable frame parts. A stable connection is obtained in particular if the releasable connecting device is formed by a known plug connection for the strut parts, which on the one hand locks the two frame parts against one another, but on the other hand is again easily detachable or closable. Such a connector may even be constructed as a snap connection, in which one part can be pushed resiliently into the other.

Wide clamps, strips or the like can of course be used as clamping bodies. be provided. However, in the case of relatively large clamping bodies, the bees have no access to the places covered by these areas, which means that there is no need to expand the honeycombs there and the honey yield per honeycomb frame is reduced. It is therefore advantageous in the context of the innovation if at least one clamping body is formed by a pair of webs which extend into the interior of the frame. As a result, the clamping body only covers a small area of the smock wall and hardly hinders the honeycomb removal. Especially when the struts are divided and with one

Connection device as well as provided with the clamping body, but also in other embodiments, may result in a complicated shape, which can only be achieved with laborious work with conventional materials (in general wood was previously used).

Therefore, according to a preferred embodiment, it is provided that at least part of the frame, for example the divisible ones Struts, preferably the entire frame, made of plastic, especially polypropylene. If at least the intricately shaped parts are made of plastic, they can, of course, be manufactured much more easily, it then being obvious that the entire frame should preferably be made of plastic and thus produced in a single operation. However, there is a certain difficulty here, because on the one hand it has to be a plastic that can withstand the temperature fluctuations in beehives without being deformed. On the other hand, it also has to be used for honey extraction or. can take heat and soapy water during cleaning. Finally, however, it must also comply with the provisions of food law and must not release toxic substances under the influence of heat. Polypropylene has been found as such a plastic.

Further details can be found in the following description of exemplary embodiments shown schematically in the drawing. The figures show: 1 is a perspective view of a preferred

Embodiment of the innovation; the Fig. 2 to 6 each an embodiment variant in perspective, partially exploded representations;

Fig. 6A shows an enlarged detailed view of FIG. 6, partly in section; and the 7 and 8 each another embodiment variant in a perspective exploded view. A frame 1 (FIG. 1) has in the usual way two mutually parallel cross struts 2 and a pair of longitudinal struts 3, 4, of which one longitudinal strut 4 is somewhat longer than the longitudinal strut 3 parallel to it. The cross struts 2 are each provided with lateral spacers 5 to achieve a distance from the adjacent frame within the stick. In this embodiment, each of the struts 2-4 is divided in width parallel to its longitudinal axis, so that the entire frame 1 can be dismantled into two frame parts 11 and 12 of almost identical design. A difference may at best be that the frame part 11 is provided with connecting pins 6 and the frame part 12 with matching connecting holes 7. However, in order to get by with a single tool for the production of the frame from plastic, in particular from polypropylene, or to simplify the necessary mechanical equipment when manufacturing from a different material, both frame parts can preferably also only be provided with connection holes 7 into which then appropriate dowels in the form of pins 6 are used for connection. Both the pins and the dowels can be designed for a snap connection with thickened ends, which are designed to be resilient, for example, through molded-in slots. For the snap Connection can then expand the holes 7, which for example are continuous according to FIG. 1, towards the outside of the frame, so that the reinforced head of the pins or dowels is fixed in the expansion under spring force.

Each of the two frame parts 11, 12 has associated clamping bodies of a fastening device for the central wall. These clamping bodies are either designed as projecting, short webs 8 or as continuous webs 9, which are preferably arranged near the adjacent struts 2, with their two ends each connected to one of the longitudinal struts 3 and 4, and thus the central wall (not shown) secure against bending their edge. For reasons of strength, but possibly also for easier removal from the mold, the webs 8 in particular, advantageously for the latter purpose also the webs 9, are wedge-shaped at least in one plane. In order not to squeeze the middle wall after insertion, all web-shaped clamping bodies 8, 9 have moved somewhat away from the inner edge of the respective frame part 11 or 12, so that a narrow space 10 remains.

Since the two frame parts 11, 12 must always be put together in such a way that the two spacers 5 face away from one another on opposite surfaces, the connecting holes 7 on the longitudinal strut 4 facing the spacers 5 can be used in other areas stands, in a different number and / or in a different cross-sectional shape than provided on the longitudinal strut 3 in order to prevent erroneously incorrect assembly of the two frame parts 11, 12 (rotated by 180 ° relative to one another). Of course, the same effect is achieved if the holes 7 on the cross struts 2 against each of the two longitudinal struts 3 and 4 are designed or arranged differently.

In order to now on the one hand spare the dowels that can be lost and on the other hand still achieve a single tool shape or simplified manufacture of both frame parts 11, 12, the arrangement of the holes 7 and pins 6 is preferably made in the manner shown in FIG. 1 that each frame part 11 or 12 has holes 7 on one side and pins 6 on the other side. This also necessarily means that the two frame parts 11, 12 cannot be assembled rotated relative to one another.

A plug connection does not necessarily have to be provided as the connecting device. Fig. 2 shows that an articulated connection of the two frame parts 111, 112 is also possible. For this purpose, the frame part 111 has on each side of a longitudinal strut part 104 a bearing pin 13 which can be inserted / inserted into a bearing recess 14 at the end of the associated longitudinal strut part 204 of the frame part 112. After inserting the middle wall between the two frame parts 111, 112, the frame part can 111 are closed, whereby it is prevented by a retaining strip 15 on the longitudinal strut 203 of the frame part 112 that its bearing journal 13 can slide out of the slot-shaped bearing recess 14. Optionally, the bar 15 and the cooperating longitudinal strut part 103 of the frame part 111 may have interlocking, slightly elastic beads 16, 17, which in each case lock the two frame parts 111, 112 to a fixed frame 101. Then the middle wall is in each case at its corners by inclined, because of the

Struts formed corners of the frame adjacent and with both ends connected to these struts fixed webs 109, which are triangular in cross-section for better demolding (if made of plastic).

1 and 2, it was assumed that the entire frame 1 or 101 should be divided. how this corresponds to a preferred embodiment. Fig. 3 is now to show how the innovation can be realized with only two divided struts, with further designs of the connecting device and the clamping body are shown.

One longitudinal and one transverse strut 304 and 302 are essentially fully and indivisible, whereas the struts 303 and 402 are divided. The middle wall can now be fastened in such a way that it is inserted against the corner formed by the struts 302, 304 is pushed. There can be beak-like widened clamping webs 208 into which the corner of the honeycomb panel is inserted. It then lies on webs 8 and 108. Now only the strut parts 502 and 503 need to be attached and fastened by means of one or more spring clips 18 each. For this purpose, the associated struts 303, 402 are provided with corresponding recesses 19, which each have a bead 117 for a firm snap fit. It can be seen that, as in FIG. 1, the

Crosspieces 8 of both strut parts come to lie parallel to one another, but in the case of crosspieces 108 they cross each other, so that for each pair of interacting crosspieces 108, one protrudes from a longitudinal strut and the other from a transverse strut. Of course, various such clamping bodies can be attached and / or combined on a frame. It is also understood that a wide variety of connection devices can be used. 4 is the

Frame divided along a dividing line running perpendicularly through the two longitudinal struts 403 ', 404 into two completely identical or identical frame halves which can be plugged together to form a whole frame 1' by means of the pins 106 and bores 107 attached to the end faces of the two longitudinal struts 403 ', 404 are. The honeycomb panel is then between the two longitudinal struts 403 ', 404 inserted into each other at a short distance 10 opposite short webs 8, the cross strut 502' next to the spacers 5 has a groove 20, the profile 20 'is indicated by dashed lines and is used to better fix the honeycomb panel by also a exerts a certain clamping effect on the honeycomb panel. This corresponds to an embodiment similar to the beak-like clamping webs 208 of FIG. 3, but with a much smaller depth. The embodiment according to FIG. 4 also has advantages in terms of production technology, because only a single molding tool has to be used to produce the identical halves of the frame 1 '.

Here it should be noted that, according to FIG. 4, the frame 1 'is divided approximately in its center along a vertical dividing line ver, but that it would also be conceivable to let the dividing line run obliquely. If the dividing line is then arranged symmetrically, two completely identical, easily and inexpensively manufactured frame parts can again be obtained. However, if the dividing line follows exactly a slope, there are thin, tapered ends of one strut of each of the two frame parts, which thin ends are naturally not dimensionally stable and tend to break out. This can be remedied by the fact that the dividing line in the area of the struts 403 ', 404 does not exactly follow a slope, but is stepped, as is customary when connecting wooden beams. The steps can also have a dovetail! seen in cross section through the strut), so that there is automatically a certain centering when connecting. However, if the dovetail is visible in the side view of the struts, there is a toothing of the two strut parts to be connected to one another, but then the use of the pins 106 is hardly possible (except for a slightly elastic design of the struts), which is why other types of connection, for example an over the dovetail connection inserted spring clip 18 (see FIG. 3) or a dowel or the like inserted through a bore running transversely through the dovetail must be used. On the other hand, it is also quite possible to move the dividing line from the center, for example to the edge, so that only the previously removed cross strut 502 'has to be attached to the ends of the longitudinal struts 403', 404 after the honeycomb panel has been inserted.

5 shows the torn-off part of a complete frame, the longitudinal struts 503 ', 504 of which have an L-profile and are connected to the continuous webs 209 on their rear, higher walls 503 "and 504'. Each of the webs 209 is one Removable web 21 is assigned, each having a bead 23 at its ends, with which it is inserted into the recesses 22 of the longitudinal struts 503 'and 504 after inserting the honeycomb plate. These recesses 22 expediently widen inwards in the manner shown, so that the bulge 23 widens again, resulting in a snap effect.

6 shows as a further variant the torn end of another frame in which the cross strut 702 connects two longitudinal struts 603 and 604 provided with guides 25 to one another. Clamp-like clamping bodies 24 are inserted into these guides 25 and pushed onto the honeycomb plate inserted into the frame. As shown in FIG. 6A in an enlarged sectional view, the brackets 24 with their angular recesses 27 are fixed in a snap-lock manner on the correspondingly designed core 26 of the longitudinal strut 603 or 604.

In the embodiment variant according to FIG. 7, the longitudinal struts 703, 704, which have an L-profile, are connected on their rear, higher wall to continuous webs 309 and have guide slots 30 on the same level, into which removable webs 121 can be inserted. Here, the spacers 105 are provided in pairs on the back of at least the webs 121 which are adjacent to the transverse strut connecting the longitudinal struts 703, 704 to one another (not specified), as a result of which it remains irrelevant which end of the web 121 is inserted into the frame at the top or bottom and therefore mistakes in assembling are easily avoided. Alternatively, all the webs 121 could be of the same type, but without a spacer 105, but the one part of a connecting device, for example a dowel hole, for optionally attaching separate spacers 105 which are provided with the other part of the connecting device (which can in principle be designed in all forms, as are also described for connecting the struts themselves).

The projections 31 of each web 121 projecting beyond the height of the frame are provided with hemispherical locking pins 29 which engage in recesses 28 of the longitudinal struts 703, 704 and thus fix the webs 121. The spacers attached to the webs 121 can be dimensioned relatively thin-walled, as a result of which a certain amount of material is saved compared to the previous embodiments, and thus both the material costs and the weight of the finished frame are reduced.

FIG. 8 shows a further embodiment, which represents a combination of the variants shown in FIGS. 5 and 7. The upper end 131 of the web 221 provided with a single spacer 205 is analogous to FIG. 7 with the hemispherical one attached there

Locking pin 129 inserted into a recess 128 of the longitudinal strut 804, the web 221 being secured against rotation by a guide 130, while its lower end is to be clamped in a recess 122 in the longitudinal strut 803 in a recess 122 in the longitudinal strut 803, as shown in FIG. This version combines the advantages of safe and simple attachment those of a further material, cost and weight savings.
