Description

The invention relates to a growth medium according to the preamble of claim 1.In particular, in an initial phase, forest tree plants require environmental protection measures which can be associated with considerable adverse effects. Merely by way of example, reference is made to a denture guard and a sweep guard, as a result of which the structure of a plant can be damaged. In addition, possible harmful effects due to rodents, bark beetles etc. The harmful influence can occur above the ground and in the widest sense be attributable to wild-but they can also occur below the ground and relate to the rootwork.For the purpose of providing protective measures, so-called growth envelopes are known in this context, namely envelope bodies which are intended to surround the plant to be protected at a short distance in order in this way to develop a protective effect against external effects, for example by wild. These envelopes are made of wood, cellulose, composite materials or plastic, wherein sufficient ventilation is ensured via perforations of the wall of appropriate size and distribution. A grid structure is also possible. The enveloping body is placed on the top side over the plant to be protected and thus stands on the bottom side.In view of the comparatively large number of plants of a foreign tree transplant to be protected, these envelopes should be easy to handle and, in particular, be transportable in a space-saving manner. However, enveloping bodies which are formed closed in the circumferential region require a considerable volume for transport. They should also consist of a material which is sufficiently resistant to weathering over a certain period of time.Against this background, the object of the invention is to provide a shell body of the generic type corresponding to the preamble of claim 1, which is suitable in particular for use as a growth shell in forest management, that is to say meets all requirements of use, in particular when applying to plants, can be used economically and can be produced easily. This object is achieved in such a casing body by the female part of the characterizing part of claim 1.The growth envelope of the invention is provided in the form of a planar blank, the unfolding of which is shown in the form of an elongated hollow structure. The blank has two free sides to be connected, which extend in the longitudinal direction of the hollow structure and which are to be connected to one another after the folding has been completed. Numerous connection techniques familiar to the skilled person are suitable for the representation of a connection, which can be used according to practical aspects, in particular taking into account the environmental conditions in forest management. These should be sufficiently stable over time, in particular under the prevailing weather conditions. The provision in the form of a planar blank brings with it the advantage of space-saving transport to the respective location of use, an aspect which is of great importance in particular for mass use.The features of claims 2 and 3 are directed to a cross-sectionally polygonal, for example square, cross-sectional shape of a growth medium. In this case, the blank is provided with a series of fold lines, technically represented by pre-punchings, by means of which the side walls of the growth envelope and a terminating wall are bounded. These walls preferably have the same size as each other. The end wall serves to provide a securing function by means of which the unfolded position of the side walls is fixed. It is accordingly equipped with means for performing this function.The features of claims 4 and 5 are directed to means for providing a guiding function so that the unfolded side walls finally assume a defined position. They are also directed to means for securing this position of the side walls, i.e. means in the manner of a locking mechanism are provided. The latter means are preferably connected to the end wall.The features of claim 6 are directed to the representation of one or more retaining webs which protrude laterally from the growth medium and are intended to receive a rod or a comparable retaining element to be anchored in the ground and in this way to secure the installation position of the growth medium. These retaining webs are located on the outer side of the growth medium casing.The features of claim 7 are directed to further measures for securing the position in which the growth medium is set up. In this case, a section is provided which is bounded along two mutually opposite sides by punchings and otherwise by pre-punchings and can be unfolded towards the inside of the growth medium, so that an angular retaining structure is produced which can be used in a similar manner to the retaining webs on the outside.According to the features of claim 8, the growth medium consists of a material which can be decomposed without residue under ambient conditions. Thus, no adverse effects on the environment arise from the growth coat.An exemplary embodiment of the invention will be explained in more detail below with reference to the attached drawings. The following are shown: FIG. 1 shows a representation of a flat blank intended for producing the growth envelope; FIG. 2 shows a three-dimensional representation of a growth envelope before the establishment of the closed state; FIG. 3 is a view corresponding to arrow III of FIG. 2; FIG. 4 shows a three-dimensional representation of a growth medium with still open closing flaps; FIG. 5 shows a three-dimensional representation of a growth medium with closed closing flaps; FIG. 6 is a three-dimensional view according to arrow VI of FIG. 4; FIG. 7 shows a three-dimensional view of the final state of use of the growth medium.The drawings show a growth medium casing intended for use in forest business, which in the initial state is in the form of a planar blank 1 shown in FIG. 1. The growth envelope is characterized by an elongated, hollow structure which is square in cross section and consists of four elongated side walls 2, 3, 4, 5 and a terminating wall 6 of the same longitudinal and transverse extension. Reference is first made to FIG. 1 below.The side walls 2, 3, 4 and 5 and the end wall 6 are delimited from one another by fold lines 7, 8, 9, 10 which are formed practically by pre-punchings of the blank 1. These fold lines form lines about which the side walls are unfolded to show the spatial structure of the growth envelope.Reference numerals 11, 12 and 13 designate inwardly foldable portions of the side walls 2, 3 with respect to the growth medium, which portions, when unfolded, have an angular shape and form inwardly oriented guides, the purpose of which will be explained in greater detail below. They each consist of two partial sections of the same size and shape and extend symmetrically on both sides of the fold line 8, and in the unfolded state both partial sections are only still connected to the side walls 2 and 3 via their sides facing the fold lines 7 and 9.Reference numerals 14, 15, 16 and 17 designate slots along the fold line 10 which are intended to cooperate with locking tabs 18,19,20 and 21 which are arranged along the outer side 22 of the end wall 6 and are designed and arranged to provide a locking function.The reference numerals 22, 23, 24, 25 and 26 designate webs which are arranged on the free outer side of the side wall 5 and which are intended to cooperate with slots 27, 28, 29, 30 and 31 which are arranged along the folding line 7 and are designed to secure the structure of the unfolded growth medium.The reference numerals 32, 33 and 34 designate retaining webs which can be folded out of the plane of the side wall 5 and are intended to cooperate with slots 35, 36, 37 which are located in the end wall 6.FIGS. 2 and 3 show the growth medium in a state in which the side walls 2 to 5 are unfolded from the blank to a structure having a square cross section, the end wall 6 still being located in the plane of the blank 1. The retaining webs 32 to 34 are unfolded from the plane of the side wall 2 and are opposite the slits 35 to 37 of the end wall 6. The locking tabs 18 to 21 are not yet inserted into the slots 14 to 17 of the side wall 2 associated therewith.FIGS. 4 and 6 show a state of the growth medium in which the webs 22 to 26 are additionally inserted into the slots 27 to 31 of the side wall 2 assigned to them.FIGS. 5 and 7 show the finished ready-to-use state of the growth medium in which the latter, standing on the ground, surrounds a plant, not shown in the drawing, here a forest plant, and in this way develops its protective effect. The locking tabs 18 to 21 are inserted into the slots 14 to 17 of the side wall 4 assigned to them and locked in this insertion position.A locking function can be produced, for example, by the fact that head parts are located at the free ends of the locking tabs 18 to 21, which head parts have undergone a configuration for the purpose of forming an undercut which is suitable for forming a positive fit with the boundary of the slots 14 to 17 assigned to them in each case.For practical use, the growth envelope is first provided as a planar blank 1 and, by unfolding its side walls 2 to 5, unfolded to form a three-dimensional structure surrounding the plant to be protected, a guiding function being exerted via the plug connections of the webs 22. The once established plug position is then secured by the locking tabs 18.A position securing of the protective sleeve can be achieved by means of a rod, a post or the like, which is received either on the outside in bores of the retaining webs 32 or on the inside in the sections 11 folded open toward the inside and fixed on the bottom side. In each case, an effect securing the position of the growth medium is obtained.The growth medium can have a profiling in the form of a toothing or the like at its lower end in order to further improve its stability.Use of the growth medium is not restricted to the field of life. It can be used wherever protection of plants in an initial stage from wild is concerned.List of reference numbers:1 Blank 2 Side wall 3 Side wall 4 Side wall 5 Side wall 6 End wall 7 Fold line 8 Fold line 9 Fold line 10 Fold line 11 Section 12 Section 13 Section 14 Slot 15 Slot 16 Slot 17 Slot 18 Closing flap 19 Closing flap 20 Closing flap 21 Closing flap 22 Web 23 Web 24 Web 25 Web 26 Web 26 Web 27 Slot 28 Slot 29 Slot 30 Slot 31 Slot 32 Retaining web 33 Retaining web 34 Retaining web 35 Slot 36 Slot 37 Slot
