The purposes are achieved by means of the greenhouse structure Invention achieved, which is characterized in that it is at least a field has »which consists of a stiff frame · which is equipped with cross members that carry a transparent plastic film that is placed between two metal » grid areas is stretched * the drti superimposed areas are immobile on the named frame, appropriate"

The mentioned greenhouse frame has two beforehand rectangular fields that are inclined towards one another in contact by their upper sides while they are on theirs Undersides immovably supported and with joints on support feet are anchored in the ground, with one of the fields called the semi-rigid field being anchored by a Rod is held, the end of which stütat the top © side of the field mentioned, and the other field, as "movable Field "denotes, is supported freelyif the first.

The above-mentioned greenhouse frame also has the following main features

the said vertical bar is telescopic and is mounted on its base on a fixed clamp with articulation,

the plastic plate goes over the lower side of the disc and forms an arch overhang that rests on the ground

connects,

the one called © plate goes over the top of the Field and "forms suffering with the plate of the other of the greenhouse frame a © longitudinal joint over the entire The ridge line of the frame is running,

the said frame is intended for others similar to be connected so that longitudinal rows are formed »whereby the peepholes between the fields of the box frames» which are set up next to each other » Plastic tape can be formed »which unfortunately goes beyond the transverse sides of the above»

The said greenhouse frame is at its ends closed by plates made of plastic material in the appropriate shape. In the case the rack is placed next to others only the outer greenhouse frames of the Heihe are included equipped with this "lock.

The device for its artificial breeding, which forms another object of the invention, is particularly characterized in that it comprises at least two parallel rows of greenhouse frames of the type defined above, the movable fields of one and the same transverse row being connected by a chain, and one after the other by pulling to be operated on the chain *

This linrlchtuag also owns the following Main features:

The support feet consist of tubes in the space between them between sswel adjacent legs are inserted into the ground, each tube equipped with a cross bar

1st that bears at its ends the fields that are on each one Side of said space and "or, the belong to both series' which limit this space?

the support leg © can be as long "that they allow cultures of high altitude, and the bands' hanging from two adjacent discs and sugehoren the two" adjacent rows, are interconnected by fixed elements, vm a longitudinal joint to form *

The greenhouse frame can be produced according to one variant to make the construction more robust and simpler and to give it a very stable shape, the withstands even strong winds.

The greenhouse frame becomes the result of this "variant characterized as having two fields, each has a metal frame made of light tubes that are made of parallel tubes Longitudinal beams are formed, which are held at their ends and in their center by three counter-curved crossbars, so that they form a field with a prismatic surface »it a polygonal cross-section that is slightly convex on the outside and has at least two, preferably three »surfaces, the fields having a plastic, transparent layer Material that is held between grid surfaces by hooks on the scaffolding «

The Gewäehahausgesteile after this variant are also for installation in continuous and parallel Strain provided and standing on T-shaped feet, whereby Each foot a movable field of a row and a semi-movable adjacent field that belongs to the love line,

Supports C of greater height (Fig. 17)> as will be explained in more detail later.

A field (Fig * 5) comprises a flat frame A ^, the is formed from two lateral and one central longitudinal beam, which are arranged in parallel »and at their ends through two cross members are connected ·. These side and cross members are made of lightweight ears that are welded to one another. On these cross members and several cross lines in between, which maintain a regular distance (in which * posed case animal lines) are the so-called "lower" Lasts A arranged from - ^ appeihölz} on these lasts the latticework 1 is stretched out of fine galvanized wire with large hexagonal machines, which over its entire length circumference of a galvanized iron wire G stronger Is hemmed in diameter, which should make the tension evenly. There is a clear one on top of this grid Plastikfoli® applied »F, (Fig. 2 and 3), whereby the material» of which it is composed, e.g. the tinyl product class can belong · On this slide there is a second lattice mechanism which is similar to the first »the one exactly on the first ixcht rests, and above it is a row of upper ones Strips A, which rests on the lower strips »around the

Tension the wire, tuck le is tea against each other pressed to their find and in their midst by. Shafts with screw thread A »which are on the Eöhrenal frame A are welded on, whereby ^ each shaft by the following there is a lower bar, the first grid »the ^ plastic film» the wide grille and a top bar »a screw

17 (L.

nut A '»which is placed on this shaft A with an intervening entry A »holds the various parts together, as shown especially in fig. 5t 6 and 7 visible.

Lan sees that the plastic film is thus clamped between the two grids and held on all sides will. It is therefore practically not subjected to any stress. It is therefore sufficient to use a thin film that is less mechanical To use resistance for this purpose, the self is safe for snow or heavy snow, and the greenhouse areas can be placed in any direction without the plastic film shifting as a result.

"To create a watertight joint between the pane and the ground, a free overhang W of the plastic film is provided, on the long sides of the fields (see Fig. 1» 2) as well as a double deflector plate to create a watertight joint between the fields F ^{a is provided} on the narrow sides of the fields (Fig. 10).

The structure described above is the same for all fields. With regard to the type of attachment, the racks are divided into semi-fixed fields A ¹ and movable racks A ² (Figs. 1 and 2) ·

-10-

The semi-fixed field A ² * (Fig · 3 1 4 · * 5) consists of a sheet metal A »which is welded onto a frame which“ is intended to hold the field immovable in its position ”and“ was through the center its highest side member on the top of an extendable tubular rod 1.

As shown in Fig. 15, "such a rod" exists on a base element B, which is intended to be inserted into the ground "on which a tube B is attached by means of a curved hinge pin D" into which an inner tube B can be pushed Hoses B and B are reinforced at their ends and provided with a locking device for assembly (Fig. 12), which in W again

it is introduced and displaceable against a return spring B. and which can be operated by means of a pull cable B

The end of the drill B ^ is on the frame of the greenhouse rack A coupled (Fig. 8) by means of a curved

Those feet that just sink into the ground if it is about the feet C for Uiederkultur, can expediently attached to a cement block E (Fig. 1?)

if it is feet C for very tall cultures. In this case, the foot is pre-pinned to a piece of metal that is clamped into the aforementioned block.

The height of the extendable rods is regulated so that the semi-fixed fields have an inclination angle of 60 °. The distance between the lower longitudinal members of the fields is kept in such a way that that the movable panel can be folded down onto the semi-fixed panel in such a way that their upper edges are adjacent to one another. The overhangs of the plastic sheets form joints on the top of the greenhouse frame constructed in this way, and in the embodiment according to FIGS. 14 and 16, the overhangs on the earth © can be covered with a small layer of earth and thus be attached.

When setting up artificial (forced) breeding According to the invention, the fields are arranged in a row and their ends are juxtaposed and arranged in parallel rows, the number and length of which are affected by the expansion of the cultures. The ropes are as far as possible Arranged east-west, while the semi-rigid fields follow the cord

-12-

are exposed (arrow Ir, Fig. 14), while the movable Discs are directed to the south (arrow S, Fig. 14),

In the embodiment according to FIGS. 14 and 16, forms the space between the overhangs of the plastic sheeting in two adjacent rows »the place for Passage and to the service! the length of the flat Quereleen the feet 0 is thus determined.

In the implementation type according to FIG. 17 for high cultures this gap is eliminated, and the two adjacent overhangs of two adjacent greenhouse racks are brought together by means of brackets I * made of steel wire » the clamps being arranged to go from one end to the other and between the successive ones Form rows of joint joints that still allow the rainwater to drain off freely »

The closure at both ends of each leg and on the overhangs of the outer legs in high cultures is ensured by separate fields in a triangle shape on the end parts and in a pike-corner shape on the high overhangs *

After all, they are all arranged in a row Fields through the service chain I »mentioned above, connected * This is subdivided for each row and has a "soft" »i.e. unpassed» point (Fig. 14 and 17) between each row «This" soft "point is designed in such a way that, when a part of the chain applies pressure a field is exercised, this rotates and then folds down onto the semi-fixed field of the adjacent greenhouse box and so to assume the position shown in Fig. 14, yet the movements of the so connected

Fields with adjustments carried out »to the highest power reduce that would be necessary for the start-up »if all fields would have to be pulled up at the same time. This maximum force is thus practically based on the necessary force limited »which is necessary for the movement of the first field.

These G-ewaxing racks can by means of an electric find to be served »who in turn are served by © inen Thermostat is activated.

At last it was seen 'that the chains were rigidly fastened are (Fig. 7) and can be released immediately can} the fields can therefore be operated in groups or alone.

The main uses of this facility are as follows.

In the closed position (Fig. 1? And H Fig. 15) are the southern fields illuminated by the rays of the sun bb (Fig. 1 ^), which follow a middle left of 90 ° "that is," without palpable absorption in the plastic film; the Hordeeheib © » which absorbs almost all of the radiation »forms a shadow zone of very little extent.

In the position shown in Fig. 14 is the direct sunlight on almost the entire culture, during a large part of the day, during which Shadow zone. Is limited to the space in between.

The height adjustment of the extendable rod allows the inclination of the panes to be adjusted to the horizontal » E.g. to 60% »which is the most favorable inclination of the panes

For irrigation you can use the Gewach & home made the Give position on Pig. 16 is indicated -. To this For this purpose, the screw nut Ir is loosened by hand (Pig, 12) and the flap A is raised to the vertical position. Then the movable shutter A throws down, exposing the whole surface of the culture,

The position of the complete exposure of a greenhouse frame (Fig. 15) is achieved by folding down two fields against each other after the chain and the pull-out bar are unhooked, one of the latter can pull out the inserted support leg to allow full and mechanical tillage.

Double winter protection can be achieved by means of a. film can be achieved »which is stretched by means of hooks on eyelets and with arch overhang on the floor within the frame as on O (Fig. 15) or by movable flaps M and M (Fig, 15) on which the Plastic wrap is attached in the same way. Flaps are hinged on the base of the fields attached in the joint and can be lifted by means of tie rods, which are operated from the outside for ventilation and the tanning »

It is clear that these disks can easily be stacked vertically since their surfaces do not have any In addition to the bars, protruding parts have strips that can be moved alternately. Such a stacking (Fig. 18)

These I & ags and these cross members are preferably made of light metal tubes and welded together »

these longitudinal girders and two intermediate cross girders

Simple hooks I * are welded on at certain intervals (Fig. 19 and 21), and double hooks are welded onto the central cross member (L ^a , Fig, 23) A coarse-meshed metal grid £ is stretched on this hook (Fig. 19, 21, 25), which is previously completely lined with a metal wire of thick G, which is supposed to regulate the tension of the grid.

A transparent plastic film F is on this grid (Fig. 21 and 23) and placed a second grid over the whole, which is also bordered by a wire G. This gives an extremely fast type of attachment and

-16-

a strong weather resistance.

The basic pipe of each field has on both ends 19 and 22) an inner welded-on sleeve A, the one Reinforcement for the rotation of the field forms on an axis which is carried τοη a foot C (Fig. 24 and 25) » As described above, this foot has a 2-shape and is fastened in the middle of the two similar rows of frames, as shown in FIG. The two fields of the same frame are thus supported by different C "feet. Spaces a b are on each of the rack rows saved, and the same foot C carries on the one hand a semi-rigid frame A from a row and another »

on the one hand a movable rack frame A of the adjoining rack frame * of the adjacent row. D _e r semi-rigid frame is supported con a pull rod B, which is placed in the joint to a base B, which in turn is mounted over by means of a sheet to the greenhouse frame in the joint (Fig. 19).

In the open position for the purpose of solar radiation, which is very often used, and in Fig. 24 is shown, the two fields are based on the other »The polygonal shape of the field section and the Fourth is the wedge angle that is formed by the Yorderflachen 4® ^ es the Fields that are formed are determined in such a way that, if one takes into account the length of the foot cross members, a field F (right Part of Fig. 24) on the field P of the adjacent greenhouse frame rests, and not with a line but

1 with the entire surface of the middle surfaces K and K these fields. This gives you a montage that “kills the wind

offers no target "and the complete stable is »even in the case of violent lindes. Dl © simultaneous Operation of the various racks is obtained in the same way as with the first version »i.e. by means of

a cable or a chain I »attached to a hook I is attached and also serves as a locking device.

You can give the feet C a great height, so proper greenhouses form the branches with branches allowed to breed. In this case it is preferable to "place the adjacent edges of two disks on one." and the same cross member to be united by means of a strip of flexible or rigid material * as transparent as possible, in the form of a gutter so that the greenhouses are rainproof.

Fig. 25 shows the racks according to the second type of Execution in the closed position (frame on the right and frame on the left) or (frame in the middle) in the completely open position * to allow manual work or ordering a motor. A double plate M for finter protection is provided consists of a plastic film that can be attached to wooden strips and withdrawn.

The hook I% is preferably given as already in Fig. 24, in the embodiment shown in FIG. 26, two oppositely directed beaks.

This hook, which is hinged to the upper hand of the movable frame, can be in the closed position of the frame latch into the hand of the other field of the same frame (© ♦ Fig. 27), since two adjacent fields are two adjacent Belong to racks that are almost vertically
