Description

Protective cover for the plant

Field of technology

The invention relates to a protective cover for a plant in the shape of a tube, on the edge of which, in the upper used position, flat protrusions are arranged, according to the precharacteristic part of claim 1.

Current state of the art

Protective covers for plants are known per se. In this context, reference is made to AT 005 520 Ul, AT 1 1 447 U1 (= EP 2 324 699 A1) and AT 1 1 667 Ul.

These well-known plant protection covers are used in an upright position on the ground and have proven themselves to protect especially young plants from animal nibbling damage and herbicides or weed killers, as well as preventing damage to young plants tillage equipment.

In the protective cover for the plant, which is known from the file AT 11 667 Ul, such a measure is made that this protective cover for the plant contains through holes in the region of the upper end of its tubular body.

From the file AT 12 496 Ul it is known to arrange rotatable flat protrusions on the edge, the upper one in the used position, of a protective cover for the plant designed as protection for shoots.

Furthermore, it is known to take such measures with protective covers for plants that these protective covers for plants are secured on the ground by pins, posts or rods in a standing position. These measures are belt regions of the wall of the protective cover for the plant, which are delimited by two mutually parallel cuts arranged at a mutual distance from each other. These belt regions lie in the region of one edge of the plant protection cover and can be bent inwards so that a space is created between the belt regions, for example in the form of a loop, and the wall of the plant protection cover for the placement of a pin, post or rod holding the plant protection cover plant, wherein said pin, post or rod is arranged inside a protective cover for the plant.

However, there is a need to place pegs, posts or poles even outside the protective cover for the plant.

The essence of the invention

The task of the invention is to create a protective cover for the plant of the type mentioned in the introduction, which can be placed on a pin, post or rod standing outside this protective cover for the plant.

The stated task is solved by a protective cover for the plant in the form of a tube, according to the invention, the essence of which is that at least one flap is arranged, that this flap in its used position protrudes outwards from the protective cover for the plant, and that in this flap at least one hole.

Advantageous and preferred embodiments of the invention are the subject of dependent claims.

Since the protective cover for the plant according to the invention is provided with at least one flap with at least one hole for one pin, or a column or rod, which in its used position protrudes outwards from the protective cover for the plant and in this protruding position can be folded down, for example, can the protective cover for the plant according to the invention should be placed on a pin, or post or rod, standing outside the protective cover for the plant. For this purpose, a pin, or post or rod, is simply pushed through the hole in the flap or, when this pin, or post or rod, is already inserted into the ground, the flap is pushed onto this pin, or post, or rod.

The protective cover for the plant according to the invention can have any cross-sectional shape, while preferred cross-sectional shapes include circular or polygonal cross-sectional shapes. The protective cover for the plant according to the invention has, for example, essentially the shape of a prism shell or a cylinder.

It is also advantageous within the scope of the invention if the protective cover for the plant according to the invention has the shape of a three-sided or four-sided prism shell.

Transparent materials such as polyethylene or polypropylene are preferred as material for protective covers for plants according to the invention. In particular, the protective cover according to the invention can be made from a blank that has been made from a plate with cavities, or a double ribbed plate. This form of embodiment has the advantage that the blank for the protective cover for the plant according to the invention can be supplied in a flat state and can be shaped into a circular or prismatic protective cover for the plant directly before use by bending the said blank into a tube shape and free the edges of this blank will connect to each other.

The connection of the free edges of the blank can be done in any way, while it is advantageous when the free edges are provided with flat projections, or tongues, and recesses into which these flat projections can be hooked or into which they can snap.

This creates a simple and reliable securing of the shape of the cylindrical or prismatic shell of the protective cover for the plant according to the invention.

The flap adapted to the protective cover for the plant according to the invention and equipped with at least one hole for inserting a pin, or post or rod, which is arranged outside the protective cover for the plant, can be adjusted in any area of the shell of the protective cover for the plant.

In one advantageous form of embodiment, this flap with at least one hole for inserting a pin, possibly a post or a rod, is arranged in the area of the shell of the protective cover for the plant, in which the ends of the blank closed in the shape of a tube, forming the protective cover for the plant, overlap each other.

In this form of embodiment, it is advantageous if the flap is arranged in the section of the shell of the protective cover for the plant, which is arranged inside in the area of the overlap.

In this form of embodiment, there is a possibility to adjust in the section of the shell of the protective cover for the plant, which is arranged outside the overlap area, an opening through which the flap in its used position, standing out essentially perpendicular to the shell, can be rotated or folded down.

A tab can be arranged in the opening in the outer area of the casing blank, which, when the flap with the hole for the pin, or post or rod, is turned out and then bent back to its position, closing the protective cover for the plant.

In this case, it is advantageous if instead of the bend of the flap with the hole, that is, the place where the flap is connected to the shell of the protective cover for the plant, on one side and the place of the bend of the tongue, that is, the place where the tongue is connected to the shell of the protective cover for the plant , on the other hand, they are arranged on the mutually opposite edges of the flap and the tongue.

In one preferred form of embodiment, the flap is formed with two holes, between which a bending line is arranged, so that the flap can fold itself, so that a greater strength of the flap with holes for a pin, possibly a post or a rod is achieved.

When the tab is pivoted to its position closing the opening, it may also be adapted to retain the folded flap in its folded position in which the flap projects outwardly substantially perpendicular to the plant guard.

It also falls within the scope of the invention that the flap according to the invention, equipped with at least one hole for inserting a pin, or post or rod, which stands outside the protective cover for the plant, can be combined with a known strip area, delimited by two cuts, which can be shaped into the inside of the plant protection cover, that is, when the belt is bent into an inward loop shape, so that the plant protection cover according to the invention can optionally be mounted on a pin, or post or rod, arranged inside it, that is, in the space between the belt area and the sheath of the protective cover for the plant, or on a pin, possibly a post or rod, standing outside the protective cover for the plant and fixed by means of a flap with at least one hole modified according to the invention. Of course, there is also the possibility of fixing the protective cover for the plant on a pin, or post or rod, which is arranged both inside and outside the protective cover for the plant.

In order to ensure that the tab remains in the position in which it closes the opening and in which it holds back the folded flap even under the influence of external influences, in one exemplary embodiment of the invention, this tab can contain a projection on its edge opposite the bending point, which extends into of the opening arranged in the area of the flap bend.

The protective cover for the plant according to the invention can contain one, two or even more than two openings in the region of its shell. These openings can be made in advance by cutting corresponding openings or holes from the blank from which the protective cover for the plant according to the invention is made. However, there is also the possibility that the material of the protective cover for the plant according to the invention in the area of the contour of the openings that are to be created can only be pre-pressed, so that the part of the wall of the protective cover for the plant, bounded by these pre-pressed parts, will still remain in the wall and the opening can only be opened as needed during the final release of pre-pressed parts.

This possibility of only pre-pressing the material of the protective cover for the plant according to the invention in the region of the contour of the flap and/or tab, instead of the flap and/or tab being cut out, is also within the scope of the invention. This allows the flap with at least one hole for a pin, or post or rod, standing outside the plant protection cover to be released from the plant protection shell and rotated to its used position by folding or folding only when the plant protection cover is to be the plant is placed on this peg, or post or pole, which stands outside the protective cover for the plant.

It is also within the scope of the invention that the material is cut loosely on three sides in the area of the openings to be made, so that flaps/tabs are formed which can protrude more or less outward from the plane of the wall of the plant protection cover as needed , so that it is possible to set the size of the cross-sections available for air passage to the required extent.

The protrusions in the form of flaps and recesses provided at the edges of the blank from which the protective cover for the plant according to the invention can be made, which are arranged according to one exemplary form of embodiment to keep the blank in a closed tube shape, can be formed by one, two or more than by two projections which protrude from the edge and are made narrower in their heel region than in their head region.

At least one recess formed on the opposite edge of the blank is formed with an undercut or, in the case of an opening, substantially trapezoidal in shape so that the projection can snap into the recess/opening, with the heel area of the projection, or tongue as the case may be, abutting the undercut area of the recess or a narrower area opening. This closing of the blank into the shape of the tube is done simply by slightly elastically deforming the material from which the tube is made, or bending it.

The scope of the invention also includes other forms of closures, by which blanks for protective covers for plants can be kept in the shape of a tube. In this context, reference is made to the embodiments shown and described in AT 005 520 U1 and AT 1 1 447 Ul.

Overview of images on the drawings

Further details and features of the invention follow from the following description of preferred embodiments according to the drawings, in which Fig. 1 shows a blank from which a protective cover for a plant can be made, and Figs. 2 to 4 in three stages of unfolding the flap of a protective cover for a plant according to the invention to its used position.

Examples of embodiments of the invention

The protective cover 1_ for the plant consists of a blank 2, for example with the contour shape shown in Fig. 1, of sheet material in the form of a sheet, for example of plastic, in particular with two cover layers and with mutually parallel transverse ribs between these cover layers, these cover layers are connected to each other by these transverse ribs. In order to be able to close the blank 2 to form a protective cover 1_ for the plant in the shape of a prismatic tube, or post, this blank 2 is bent along the four edges 3, 4, 5. and 6. and shaped into a tube, while the flat protrusions 7., or tongues, on one edge 1 of blank 2, are inserted into holes 9 in the area of edge 6, so that blank 2 is held in a state transformed into the shape of a tube, or possibly a four-sided prism, see Fig. 2 to 4.

It can be seen from Fig. 1 that the protrusions 7 on the edge of the 8th blank 2 have a heel area that is narrower or shorter than their head area, while the head area is laterally bounded by oblique edges, so that the protrusion 7 has an overall trapezoidal shape.

The holes 9. prepared in the blank 2. in the area of the edge 6. are formed in the shape of a trapezoid, whereby such a measure is taken that these protrusions 7. snap into the area of the short edges of the holes 9 with their heel area after the blank 2. has been closed into the shape of protective cover £ for the plant.

A form of design of the protective cover £ for the plant is advantageous, in which in the wall area of the tube, which forms the protective cover £ for the plant according to the invention, loosely cut tongues £5 are arranged on three sides, which can be pushed out more or less far from the wall as needed , to create openings with a smaller or larger free cross-section.

In the area of the edge 4 of the blank 2, a strip-shaped area 16 is created, bordered by two notches 17, possibly pre-pressed parts. This belt-shaped area £6 can be pressed inwards with the blank 2 closed in the form of a tube and then delimits the storage space £8, see Fig. 3, which is formed between the belt-shaped area 16 and the shell of the protective cover £ for the plant, and in which a pin, possibly a post or a rod can be placed, holding the protective cover £ for the plant.

Although not shown in the drawings, protrusions which are pointed or trapezoidal may be provided on the lower edge £0 of the plant guard blank 2 to push the plant guard £ into the ground for better securing .

Swingable flaps may be provided on the upper edge 11 of the plant protection cover 5, although this is not done in this embodiment.

The protrusions on the lower edge 10 of the protective cover 1 for the plant are known from the files AT 005 520 Ul and AT 1 1 447 Ul. The flaps on the upper edge H of the protective cover 1 for the plant are known from the file AT 12 496 Ul.

In one embodiment according to the invention, a tongue 20 is freely cut on three sides of the blank 2 for the protective cover 1 for the plant in the area 12 between the edge 3 and the free edge 8 of the blank 2, so that this tongue 20 can be around the bending line 21, i.e. the bending point which can be pre-pressed in advance, tilted outwards from the plane of the blank 2 when this blank 2 is closed in the shape of a prismatic tube forming a protective cover 1 for the plant. The tab 20 carries a protrusion 22 on its upper edge, opposite the bending line 21.

In the region 13 of the blank 2, which lies between the edge 6 and the free edge 14, a flap 30 is freely cut out on three sides. This flap 30 can be folded out of the blank 2 closed in the form of a tube around the bend line 35, or the place of the bend protective cover 1 for the plant. In the illustrated embodiment, this flap 30 contains two openings 31, 32, between which a bending line 34 is arranged.

In the area of the flap 30, which is adjacent to the bending line 35, a cut-out 33 is provided.

The fold lines 34 and 35, which allow the flap 30 to be folded out and folded back on itself so that the two openings 3 1 , 32 lie flush with each other, can, like the fold line 21, be punched in advance.

In Fig. 2 it is shown how the tab 20 arranged in the region 12 of the blank 2, which is formed in the closed state forming the tube, is folded outwards, so that the flap 30, which is arranged in the region 13, lying inside the region 12, is accessible by its through both openings 3 1, 32. The flap 30 then swings upwards from the position shown in Fig. 2 to the position shown in Fig. 3 and the tab 20 swings back again to its position parallel to the wall of the protective cover £ for the plant, while its projection 22 extends into the recess 33 in the region of the bending line 35 of the flap 30. Now the flap 30 itself folds around the bending line 34, so that the openings 31, 32 in the flap 30 match each other. Thus, the flap 30 is ready to insert a pin, or post or rod, which is arranged outside the protective cover £ for the plant, and this protective cover £ for the plant can be fixed on this pin, or post or post or rod, which is not shown.

Even though in the illustrated embodiment, the flap 30 is provided in the area of the plant protection cover £, in which this plant protection cover £ is formed in two layers, see the overlapping areas £2 and £3. of cut 2 - where the area £2 of cut 2, lying between the edge £ and the free edge i, and the area 13 of cut 2, lying outside the edge 6 lie on top of each other - the flap 30 can be arranged at any other place of the protective cover £ for the plant.

At the same time, such a measure can be made that the flap 30, possibly with only one hole 3 1 bars, is also only pre-pressed, so that the flap £0. is only flipped out as needed by releasing it from the wall area, i.e. the shell of the protective cover £ for the plant, and the opening 3 1 in it is made by breaking out this cut-out.

However, this form of execution according to the invention has the advantage that the openings in the blank 2, or in the shell of the protective cover £ according to the invention, remaining after the flap 30 has been folded out into its used position, see Fig. 4, are closed again by the tongue 20 folds back to its position shown in Figs. 3 and 4.

In summary, an example embodiment of the invention can be described as follows:

In the plant protection cover £, a tab 20 is cut out on three sides in the outer area 12 in the area where the areas £2, 13 of the blank 2 closed into the tube shape of the plant protection cover £ lie on top of each other, so that this tab 20 can be tipped out of the protective cover £ for the plant out. In the inner area £3 of the blank 2, a flap 30 is freely cut out on three sides, in which two holes 31, 32 are prepared for inserting a pin, or post or rod, arranged outside the protective cover £ for the plant. The flap 30 is folded outwards around the bending line 35, then it itself is folded back, after which the opening thus created in the shell of the protective cover £ for the plant is closed again by folding back the tab 20 into this opening, which closes this opening.
