DE3328747A1 - HILLBED FRAME - Google Patents

Description

The invention relates to a rectangular raised bed frame made of metal, wood, plastic or the like.

A special form of cultures are the so-called hill cultures, that have existed since people learned to horticulture according to plan. So-called hill beds are used in gardens applied. It is assumed that when a hill bed is laid out, a rectangle of approx. 1.5 χ 3 m is approx. 30 cm deep is excavated. The multilayered filling becomes concentric, starting from the longitudinal axis, around this imaginary longitudinal axis Made of coarse and increasingly finer material. In the final state, the hill bed should have the shape of a half cylinder.

Following the instructions in gardening books, you start with the filling with very coarse parts of plants, e.g. wood, branches, sunflower stalks etc., which are always introduced concentrically around the imaginary longitudinal axis of the half cylinder. At the very end a fine layer of humus and compost mixture comes as a cover. Such a hill bed, which is now about 1.5 m wide and is approx. 3 m long, has a height of approx. 1.3 m.

most gardening enthusiasts just wishful thinking. But even if a particularly careful gardening friend succeeds in such an artistic half-cylinder in the manner described and
Wise to manufacture, he will not long be able to enjoy it. A number of subsequent problems are already preprogrammed. The relatively steep side walls of the half-cylinder at the lower edge allow unhindered that even with the ^! Planting the so laboriously piled up humus and compost mixture j in large quantities to the side, eg on the path, rolls, whereby j the bed becomes lower and flatter and loses its desired 'original shape more and more. The bed and the path run:

It is undeniable that the long roots of many plants!

do not grow to the imaginary center of the cylinder in order to

would like to have. There is definitely the condition that some j

Plants want what the other plants have too much. J

Another disadvantage of these hill beds is that ι

always one side of the hill facing away from the sun and less

receives direct radiation. In addition, digging the ί

Soil to border the bed on the side is tedious.

Covering a hill bed with foil or a roof ^! at a distance from the ground against frost is difficult. Disadvantageous
is also that this type of hill-bed is at its center

Normal cold frames are placed on the floor. A pit in the ground picks up the compost and plant material. The cold frame practically envelops an air space above the pit. The top of these cold frames usually faces south inclined in order to achieve a favorable sun exposure, whereas the earth with the plant matter is absolutely horizontal and therefore the most favorable sun exposure is withdrawn. This is not so pronounced with a cold frame, its The frame is partially filled with earth and is closed at the top with a removable light hood. The plants can in the dome grow into it. The walls of this cold frame are strongly insulated against the cold. It has been shown that through the insulation of the walls creates a refrigerator effect, i.e. in the Spring, the sun hitting the walls can do the insulation Do not overcome the walls to warm the soil in the early bed box. The soil can at best in this box be slightly warmed from the surface.

Even when the earth's surface is horizontal, the effect of solar radiation is increased considerably reduced. The well-known south-facing effect is no longer applicable.

The invention has for its object to provide a frame for a hill bed which prevents the food supply and the growing conditions of the plants grown in the bed are different and improved in the spring and ensure that that the special structure and functionality of the hill bed is preserved for several years.

To solve this problem, the invention is based on a rectangular 'angular frame, such as those of spring beds or drifting beds is known, whose one longitudinal side wall is formed higher than the other and whose two transverse side walls are taper accordingly from the high to the lower longitudinal side wall and provides that all are detachably connected to one another

which side walls at the top and bottom have a U-shaped profile on the outside that is open at the bottom and at the top, that the approximately horizontally protruding webs of at least the longitudinal side walls are spaced apart openings for receiving rod-shaped carriers, hooks, plugs or the like and that on the outside of the Side walls at a distance from these a heat radiation-permeable plate or film, in particular. Made of plastic, detachably attached is. The rod-shaped carrier can serve to accommodate a roof-like cover or wall elements that are attached to are releasably attachable to them.

The rectangular raised bed frame prevents the bed from spreading over time, even though it is above the level a garden and is laid out without excavation work. In addition, it is no longer necessary to modify the individual structure of the Layers that make up hill beds are to be applied concentrically to a longitudinal axis. Rather, the layers to be introduced can Layer by layer, similar to the structure of a multi-layer cake. This simple work can also be done by inexperienced allotment gardeners can be run without a problem. In contrast to the well-known cold frames and greenhouses the hillbed border is completely filled with material that is adapted to the growing conditions of the plants. After the material If you have had a few days to sit down, the filling will be raised a little so that it is more or less flat afterwards To maintain area. All plants on the surface of a hill bed filled in this way become the same down to the depth Food and the same growing conditions are offered. The water permeability is uniform over the entire planting area. It is practically impossible to wash away the fine layer to the side. If the holes are not in use, through These are rods through plastic plugs or the like closed so that no snails get into the bed through the holes. The poles can only be removed from the bed

framed. After going up and down from the U-profile are held, they are always upright and can be easily and visually set up by a layperson without any effort will. The fact that a U-shaped profile is provided on the upper edge of the side walls, reptiles, especially. Snails, often prevented from reaching the plants. The formation of a profile at the bottom of the Side walls make it possible to store sawdust, ash, lime or other defensive material there in a way that is safe from reptiles. Another advantage of the hill bed framing is that the weeds from the surrounding area cannot easily get into the bed can proliferate. The frame creates a clear demarcation from the surroundings. Paths to the side always stay clean. It is prevented that e.g. raspberries leave the bed via underground runners. The desired solar collector effect through the Framing falls in the cold season and at this time there are no snail problems, so that the formed Screw barrier can be overridden. In the hot summer time there is no frame around the hill bed Plates, through which the screw barrier becomes effective.

If the holes are not used by rods, they are closed by plastic plugs or the like, so that no snails can get into the bed through the holes. The bars are only held in place by the frame. After them up and are held below by the U-profile, they are always straight and can be easily and visually easy for a layperson good looking to be set up.

The tomato friend will, for example, introduce stick elements that have a desired Wear a protective cover against rain. The sticks also hold the tomatoes. The molon friend and cactus friend becomes the Roof elements also anchor convertible ducks in the breakthroughs in order to concentrate as much heat as possible and the bean planter will put up sticks that beans can cling to.

One embodiment of the invention provides that the supports received by the openings in the longitudinal side walls are in pairs by roof girders parallel to the transverse side walls with each other are connected. This makes it easy to apply foils or roof-like covers. By such roof racks you can lower or higher protective covers against the sun or cold or at long. Easily apply and change when it rains or, ultimately, against bird damage.

The U-shaped profile provided on the upper edge of the side panels expediently has a wider, approximately horizontal web than the lower U-profile. This doesn't just get snails it is difficult to overcome but the upper profile acts like a roof with respect to the lower one, so that material is stored there is even better protected.

Another embodiment of the hill bed frame provides that a close-meshed floor wire grid is provided, which is attached to at least two opposing side walls are attached near their lower edge. This is preferably done by that the wire mesh is hooked in near the lower edge of the side walls pronounced tongues.

Such a close-meshed wire mesh offers sufficient defense against field mice and voles, for example. Only after hanging the close-knit The hill bed material is placed in wire mesh.

In early spring, the hillbed with the frame-shaped Easily protect the wearer against the cold with a film cover. The foil cover can reach the lower edge the frame. In this way, not only is the bed surface warmed by the incident sun rays but also the cavity between the film and the preferably dark frame, creating a solar collector effect arises. The warm air in which now the

The hill bed is all around, also warms the side facing the sun facing away from the walls of the bed and thus the floor and protects them and the container contents from being too fast and large Cooling off at night.

It has proven to be advantageous if, according to a further embodiment, a transparent one on the outside of the side walls Plate or film, especially made of plastic, is detachably attached. In the colder months of the year, these form covers as well as a foil cover above the frame protection against the cold and act as a solar collector, so that incident The sun's rays not only heat the bed surface, but also the side walls, which in turn warms the lower lying areas Erdreichs leads, which is particularly desirable, since the hill bed built up within the frame according to the invention is above the normal level. The border of the bed is preferably made dark on the outside, so that the cavity between the frame and the cover plate or sheet warms up well.

Thanks to the clean border of the bed, the plant area is neatly and neatly covered compared to a bed possible that has all the unevenness of the earth's surface.

Since the surface of the bed is higher than the edge area of known hill beds, it is more convenient to work because you can don't have to stoop too much. If there are several hill beds one behind the other, there is a possibility that you will be working one bed sits on the other edge of the other bed and thus does its work even more effortlessly, what is especially beneficial for older gardening enthusiasts.

Each bed of several beds can easily be provided with a different soil mixture that corresponds to the respective

Plants is adapted without the soil being mixed with the soil of the surrounding area after a short time.

An embodiment of a hill bed frame according to the invention is explained in more detail with the aid of a drawing which shows:

Fig. 1 a hill bed frame in an oblique view,

FIG. 2 shows a perspective cross-section through the hillbed frame according to FIG. 1,

3 shows a perspective oblique view through a section of the frame with the cover film applied,

4 shows a perspective sectional view of a hillbed frame with supports for receiving a flat roof-like cover,

5 shows an oblique perspective view of part of a hill-bed frame with a pointed roof-shaped attached Cover, and

6 shows an oblique perspective view of part of a hill-bed frame with the side walls attached clear plates.

The hill bed frame 1 shown in the figures comprises a lower, front longitudinal side wall 2, a higher rear one Long side wall 3 and two transverse side walls 4, which together form a hill-bed border with a rectangular cross-section. In a manner not shown, the four side walls are at the corners releasably connected to one another, in particular by screws.

Each side wall 2, 3 and 4 has a downward at the top open U-shaped profile 6 and at the lower edge an upwardly open U-profile 6. If the side walls 2, 3 and 4 are made If there are sheet metal, these U-profiles can be obtained by double folding. When using other materials, which cannot be bent, separate U-profiles 6 can be attached here. The approximately horizontal crosspiece 7 each U-profile 6 at the upper edge of the side walls is slightly longer than the corresponding horizontal web 7 of the U-profile at the bottom of the side walls to act as a roof and increased resistance to reptiles.

In the approximately horizontal webs 7 of the U-profiles 6 on the upper and lower edges of the side parts, each of which is attached approximately vertical web 8 adjoins, there are at a distance from one another and one above the other perforations 9, in the rod-shaped Carrier 10 can be inserted, on which plants climb up.

Along the lower edges of the longitudinal side parts 2 and 3, tongues 12 are formed, which serve to insert in the bottom opening the frame 1 provided close-meshed wire mesh 13 to accommodate. This wire mesh is used to protect against voles, which because of the special structure of a hill bed like to nestle in it.

In the cavity of the lower U-profile 6, a layer 15 of lime or ash can be filled, which prevents the penetration made difficult by pests. After setting up the hillbed border, it is initially made of coarse layers 20 and filled with ever finer material towards the top. Various plants 21 particularly thrive in this hill bed good growing conditions.

To catch just during the cooler season To facilitate warmth, a cover is provided both above the free area and in front of the side walls. The embodiment according to FIG. 3 is a Cover in the form of a transparent plastic film 24 that covers both the side walls and the free cross-section continuously. Heat not only accumulates above the ground but also in the cavity 22 between a side wall and the laterally spanning plastic film 24.

The covering of the side walls to form a cavity can also be formed by plastic sheets or foils attached to the vertical webs 8 of the U-profiles 6. These are expediently detachable, so that during the warm season there is too much heating from the side is avoided and the lower U-profile 6 with lime or the like can be filled.

In the embodiment of FIG. 3, one is only on the top effective coverage provided. For this purpose, brackets are in the openings 9 of the protruding webs 7 of the U-profiles inserted, each consisting of two vertical rods 10 and one of these in pairs parallel to the transverse side walls with one another connecting roof rack 11 exist. On top of this is a corrugated plastic sheet 25, which keeps out too strong sunlight but can also protect against too long exposure to rain. Flat plastic panels or thicker foils can also be attached to these carriers, the latter similar to awnings.

FIG. 5 shows an embodiment of the hill bed frame 1 in which it is covered by a pointed roof-like cover 30 is, in this case rod-like carrier 10 in openings 9 in the horizontal webs 7 of the upper and lower U-profile 6 of the transverse side parts 4 are held, the are connected to each other with a ridge roof rack 11 ', so

i 57 414

that a larger plastic film like a tent over this ridge roof rack 11 'and over at least the upper profiles 6 of the
Long side walls 2 and 3 can be stretched. Special
Side parts are attached in front of the transverse side walls 4 in the two end faces. This cover is useful when in particular there are taller plants in the middle.

Fig. 6 shows another embodiment of the hill bed frame 1, in which heat radiation-permeable transparent plates 26 are set outside in front of the side walls at a distance from these obliquely in the space between the U-profiles 6, so that the
Frame 1 also acts as a solar collector here. The plates 26 are curved inward in a wavy manner at the lower edge and overlap with the wave profile 27 the upper edge of the outer vertical
Web 8 of the lower U-profile 6.
