Holding device for field and garden foils

The invention relates to a holding device for field and garden foils.

Such field and garden films consist in a known design made of plastic, for example PVC, and have a low thickness. Tiles, for example made of non-woven material, which is porous as a whole, are also included. Such material is to be used in a non-perforated design and perforated, or it is provided with holes. These and corresponding materials are used to cover beds in gardening shops or in agriculture also fields in order to achieve a build-up of heat under the foils when rain penetrates. The purpose of this is to accelerate the growth or ripening effect in rainy and inhospitable weather, especially in spring, in order to achieve at least an earlier, but advantageously also a better harvest.

All of the above-mentioned materials and designs of foils are referred to below in the expression "field perforated foils" included.

Such field perforated films are available as webs, for example 8 m wide and 100 m long known, these sheets are laid on fields. The edge of the webs is held by holding devices held down.

\ Are anchored to the ground. When the field perforated films are inflated

such edge weights are often thrown off.

; In addition, there is the problem that with increasing

Growth of covered plants the field hole foils with ab-

to inhibit. The known loading devices are there-

for not suitable.

The invention is based on the object ₄ to provide a holding device for field-apertured films, which causes at least a reliable and easily deployable edge support on the ground, but a.uch in the preferred embodiment an insert for increasing and raised mounting a field-hole film without particular Effort allows.

This object is achieved according to the invention by a plug-in foot one laterally protruding clamping piece and one arranged on the side of the clamping piece facing away from the plug-in foot Handle released. The plug-in foot can be stuck into the ground and anchored as such, with the one protruding to the side Clamping piece engages over the edge of the film and fixes it on the floor by indenting it. The handle makes it easier the handling.

;. It is particularly preferred that the clamping piece in

Plan view on one side with a surface extension of about;: 90 is arranged protruding in relation to the plug-in foot. Through this the prerequisite for a special design of the holding device results, which must be taken into account

1; ■ ca * ■ a f ♦ # · · ■ »· *

is that a holding device is generally arranged on one side of a film web.

It is expedient that a clamping piece is arranged rotationally symmetrically around the plug-in foot, in particular two clamping pieces, each extending over an angle, are provided diametrically to one another. This takes into account that when a field is covered with, for example, approximately 8 m wide strips, the edges of adjacent strips can be fixed by a plug-in foot.

Such a clamping piece can be arranged like a disk or as a sector surface on a plug-in foot. According to the particularly but are preferred embodiment of the invention the clamping pieces as clamping webs in the course of a multiple bent rod-shaped material forming the device executed. This enables not only a light design, but also easy production, which can be kept clean in repeated use.

It is particularly preferred that the handle as a rod piece directed essentially parallel to the plug-in foot is executed, which can also be used as a further plug-in foot and is laterally offset from the axial projection of the plug-in foot is. As a result, the holding device can optionally be inserted with its two ends downwards, whereby a so-called plug-in foot section serves as a handle. The lateral offset, which also occurs when running with a Handle is involved, has the first purpose that the upper end of the to be driven into the ground Plug foot is accessible from above, so that the holding device either by striking it with a hammer or by stepping on it can be driven into the ground.

K · ■

The further plug-in foot is advantageously made longer than the plug-in foot. Herein lies a meaning of execution of the handle also as a rod piece, because this creates the prerequisite that the laterally protruding Clamping piece with the same insertion depth of the holding device once directly on the ground and on the other with Distance above the floor can be arranged. The ground anchoring force is the same in both cases.

It is particularly preferred that the clamping piece as part of an angled rod piece with an arcuate course is executed and contains the clamping bar, and that between the approaching the plug-in foot, serving as a plug-in feet Rod section sections a distance is maintained. This not only makes it light and easy to manufacture Execution created, but through the mentioned distance also the possibility of threading the field perforated film, if the middle area should be pulled up and held up at a distance from the held down edges. This is a particularly advantageous embodiment. It is preferred that the clamping piece on one side of the rod piece or with respect to the two rod section sections which each form a plug-in foot and are offset from one another in the projection is arranged.

According to an expedient embodiment, the form is arcuate Course of the angled rod section essentially triangular. The triangular shape has the advantage of being elongated Execution of the clamping bar, which can therefore perform its task particularly well.

It is expedient to include that the arcuate course of the angled rod section is essentially rectangular

is designed with rounded corners. This also results in the prerequisite for a favorable arrangement of the Clamping or supporting a section of film. One The circular shape of the arcuate course has the advantages of being easy to manufacture and of a special design also a possible use, especially the ability to be supported in all directions.

In all versions, an advantageous embodiment is that the clamping piece or that of the angled Rod piece bounded surface is inclined downward at an angle of about 75 ° relative to the plug-in foot. This will on the one hand, it makes it easier to pinch a field perforated film at the edge, it is also possible for a bead or a certain rolled edge to be overlapped. On the other hand results however, when used the other way round, the field perforated film is supported in the middle area, with such a shape also facilitates clamping in a manner to be described.

The above statements advantageously include the fact that a rod piece for the arrangement of two clamping pieces is bent in the manner of a figure eight, with gaps in the transition between adjacent rod section sections remain.

The above-mentioned lateral offset with respect to the plug-in foot and handle between adjacent ends of the formation of the As already mentioned, the clamping web advantageously leaves a distance for threading through a field perforated film. So is the size of the lateral offset is not only determined by the fact that, for example, it is driven in with a tool is facilitated, but that a field perforated film of any thickness with tension in the surface extension Can be threaded through the holding device is rotated. This means that a plug foot

«· ·« Et ·· tei

put through a hole in a foil and driven into the ground and then when the foil the angled clamping piece has reached in the form of a bent piece of rod, is rotated so that the edge of the hole of the film on the top of the clamping piece comes. The execution of the plug-in foot as a rod piece facilitates the rotation.

It is preferred that the rod piece material with a profiled, in particular with a flake-like roughened surface, is executed. It is also expedient to make the rod piece material from reinforcing steel with ribs, in particular helically arranged ribs included. This results in a particularly favorable anchoring, but above all the prerequisite for the definition

another part of the device. This further part consists of one on the plug-in foot, handle or further Plug-in foot push-on retaining clip with a pressure cover for at least the clamping bar. This is one particularly advantageous further embodiment, especially for use to lift off the perforated field film in the middle Area to create a kind of cold frame.

In an expedient embodiment, the pressure cover is in this case run resiliently with respect to the retaining clip and has at least one of the clamping web covering and on its outside lowered edge. As a result, the section of the perforated field foil that lies on it can be firmly attached to the clamping bar being held. This is particularly important when the wind influence is taken into account and prevented should, that this reaches under the raised field perforated film in its central area and lifts off.

In an expedient embodiment, the retaining clip is designed as a pipe section, the inside diameter of which is oversized

is carried out in relation to the rod piece material. A sol-

* ches pipe section can be roughened like scales

In a particularly preferred embodiment, a retaining clip is included as a slotted tubular piece made of resilient Material that forms a clamping clip. Such a retaining clip can and will be set on one side held by the resilience on a plug-in foot, the definition is further improved by the roughened surface.

A pressure cover with an elastic spring clip, which is a hook-like one, is also expediently included Has two-arm support on a plug-in foot or handle, the upper arm of which is a rod piece with respect to lateral extension the spring clip from the front, and the lower arm of which grips the rod from behind.

The invention is described below with the aid of advantageous exemplary embodiments shown in the drawing are shown. In this show:

In all figures, the same parts are denoted by the same reference numerals.

In all versions, the holding device has a plug-in joint 1 which can be inserted into the ground and thus anchored the holding device in the ground. Up is, as shown in Figs. 1 and 2, at least a handle 2 is provided with which the holding device can be easily operated. Such a handle 2

- 9 -

can also be seen in the plan view according to FIG. 3.

A laterally projecting clamping piece H is ^v in FIGS. 1 and 2 designed as a disc part or surface 5, which is pushed onto the plug-in foot 1 and fixed on this, for example, by welding. The surface 5 in FIGS. I and 2 has an essentially triangular shape and an edge 6 facing away from the plug-in foot 1, which runs in the manner of a clamping web, ie when the plug-in foot is driven into the ground itself with its entire extension to the The floor can be guided or pushed into the floor. For this purpose, the clamping piece H is expediently arranged at an acute angle to the plug-in foot 1 or is designed in an arcuate shape with the side towards the plug-in foot 1 concave.

In the embodiment according to Fig. 2, two clamping pieces 4, 4 ' arranged diametrically to each other and at an acute angle to the plug-in foot 1, to films on both sides of the plug-in foot to be trapped on the floor.

Fig. 3 shows a simple embodiment with a clamping piece 4 in the form of a circular surface 7, which has a rotationally symmetrical Pressure around the plug-in foot 1 or handle 2 on the ground is possible. To always have an impression To allow into the ground, the surface 7, which is circular in plan view, is advantageous than it opens downwards Conical or bell opening downwards.

FIGS. 1 to 3 show simple configurations. The clamping piece 4 in FIGS. 1 and 2 can have a surface extension have in plan view of 90 ° with respect to the plug-in foot 1.

- ίο -

4 shows a particularly preferred embodiment of the Toriri with a clamping web 8 in the course of a multiple bent, J rod-shaped material 9, which forms the holding device. • The part previously described as a handle is designed as a directed rod piece, which can also be used as a further plug-in foot 10 in the ground, essentially parallel to the plug-in foot 1. Here, that the plug-in foot 1 and the further mounting foot 10 is substantially \ parallel but laterally offset from each other is to be noted, extend ft. The lateral offset is shown in FIG. H with 11; draws.

! The perspective view in Fig. 4 shows that the further plug-in foot 10 or this rod piece is longer

. than the plug-in foot 1 is designed. This means that depending on the use of part 1 or 10 in the bottom of the clamping bar 8 is arranged more or less above the ground,

f albeit the depth of the device in the ground is equal to.

FIG. H also shows an essentially triangular course of the angled rod piece, the clamping web 8 running essentially in a straight line.

In Fig. 5, an embodiment can be seen which is comparable to that in Fig. 2 by the rod piece in the manner of a Eight is bent and thereby the clamping bars 8, 8 'in arcuate courses are formed of a substantially triangular shape. But always in In the area of the bends, leave spaces 12, 13 so that a film can be threaded into its hole

For example, the plug-in foot 1 is inserted and then pushed up on the plug-in foot 1. In the area of the bend the entire arrangement is then rotated so that the film next to the impaled hole on the top of the clamping webs 8 or 8 'arrives, which then serve as support webs.

With such an arrangement of the film, it is expedient to hold it and to prevent it from lifting off the clamping webs 8, 8 'to prevent. For this purpose, a slide-on retaining clip 14 with a pressure cover 15 for at least the clamping bar 8.

5 shows an embodiment in which the bent parts of the rod piece material are each angled to the plug-in foot or the further plug-in foot or handle 10. Here, the angle to the plug-in foot 1 with respect to the horizontal is approximately 15, ie to the plug-in foot 1 itself in the order of 75 °. This also applies to the other designs or a conical design of the circular surface 7 of the clamping piece ¹ J.

The retaining clip IU and pressure cover 15 are shown more clearly in the side view according to FIG. It can be seen that the ^{retaining clip I 1} J surrounds an upwardly projecting part or plug-in foot 10 and is fixed to it. The nip cover 15 passes through the example of FIGS. ¹ J and 5 cavity formed next to the clamping bar 8 downwardly and then extends with an arcuate portion and lowered at its outside edge 16 on the clamping web 8, so that occurs at this a holder , even if with the reverse arrangement the clamping piece Ί with

- 12 the clamping bar 8 is directed obliquely upwards.

The pressure on the pressure cover can be improved by a central rib 17 or is instead of middle rib arranged a spring clip., which the outer edge of the pressure cover with the arcuate section pushes down.

In this context, there is a self-tensioning and resilient design, as can be seen from FIG. 7. In this embodiment, the retaining clip 14 is designed as a pipe section 18, which is the effect of the resilient tension between the pressure cover 15 or the spring clip 17 on the one hand and the pipe section 18 on the other hand tilted and fixed against upward movement at 19 on the further plug-in foot 10.

This design is particularly suitable when the rod piece material is designed with a scale-like roughened surface, as shown in the various figures at 20 is. Such a surface design also promotes the establishment in the ground.

FIG. 8 shows a top view _s in which the upwardly directed rod piece 10 or also the so-called handle 2 can be seen. In this embodiment, the retaining clip 14 is designed as a slotted pipe section 21 so that it can be attached to the side as a clamping clip and is retained due to its spring action.

In Fig. 9, a field perforated film 22 is shown, the beaded edge or rolled edge 2 3 of a laterally protruding Clamping piece 4, in particular with a clamping web 8, over-

jj foot 1 inserted into the ground. The other one protrudes upwards

At a distance from this, a corresponding holding device with the longer plug-in foot 10 with the same bottom depth is used, so that the clamping piece 4 with the clamping web 8 protrudes obliquely upwards. The slide is passed over it surrounds the plug-in foot 1 with a hole. At this point aieses hole 23 is reached after the further plug-in foot 10 has been inserted into the top of the hole the film 22 raised and rotated the plug foot, so that by means of the distance 11 in Fig. 4, the film on the Top of the clamping piece 4 and reaches the clamping web 8. This situation is ensured by the retaining clip described secured with the pressure cover 15. It can be seen that the plants can then develop underneath the foil 22 without stress.

10 and 11 show, according to the embodiment according to FIG. 1, advantageous configurations in other embodiments. That Rod piece material has a profiled surface. In these versions, it consists of so-called reinforcing steel III b with ribs. These are applied helically in the embodiment shown. They extend also along the sections 25, 26 of the bent., arc-shaped course to form the so-called Klemrateile. Figures 10 and 11 show designs that are particularly easy to manufacture and also provide support the raised field perforated film are well suited. In the case of the embodiment according to FIG. 11, this also results, depending on the inclination of the section introduced by the bend 26 or the clamping piece 4 formed thereby, a defined Clamping web 8, which is assigned a parallel section. This forms good conditions for the attachment a retaining clip 14 with pressure cover 15.
