Description
SUBSTRATUM CRATE FOR PLANT CULTIVATION AND TRANSPORTATION
The invention concerns a plant gubs~ratum crate, particularly for use in the cultivation and transport of arboriculture plants.
Various transport stages have been known which are used specifically for the transportation and moving of goods to storage and from there to the buyers of the goods. The elements associated with stage structures allow the stages to be piled one upon another and ~oined with each other, keeping the stages exactly one on top of another, thereby preventing them from sliding off-stack.
Such stage and case structures are likewise known per se, the structures often designed to be piled and when ?iled as empty capable of fitting into a low space. Likewise, when the structures are loaded they can be piled i.e. stacked so that the cases are higher in regard to each other, so that when stacked, enough space for storing will remain in the cases.
Recently, an fdea has been increasingly adapted for plant cultivation, for reforestation and also for horticulture, according to which the plants are grown in special cases, into which the growth bed, i.e. substratum is placed.
It is endeavoured to further develop such a method whereby the plants would be delivered to shops in the same cases 9 resulting in considerable handling and transport costs being saved. However, the exi~ting stages and cases have not been satisfactory. Generally the defect has been the shape, requ~ring much space in use as well as during transport, when piled one upon another. An additional drawback has been the poor durability of the structure taking mainly nto consideration the transport of fully loaded cases piled one upon another.
There exists another drawback; due to the fact that the stack structure, when transported as piled, does not allow sufficient space for the plants.
A new type of case is described herein for transportation of the plants and substratum for the plants, which i8 superior to known cases and is ~ost suitable for the cultivation and the transportation of plants, particularly for :, ~

use in forest planting. Further, economic mechanical hoisting equipment can be used during the handling and transportation e.g. a truc~ etc. The present transport stage or substratum crate for plants can be piled upon another such crate as securely as possible so that the strain of piling is divided favoursbly, with the result that the cases/crates endure heavy loads. As another feature, piling and grabbing devices are intercontrollable, so that the plles or stacks are even during the transport and swaying of the vehicle do not tumble down. It is also a feature of the present case/crate that the substratum of the plants is easy to unload and the structure allows air to enter below the crate and through the bottom into the substratum.
Thus the present invention provides a substratum crate assembly for use in plant cultlvation and transportation, comprising:
a latticed bo~tom member of substantially rectangular configuration with a p~ir of side walls and a pair of end walls su~rounding and extending substantlally perpendicular to said latticed bottom member;
a plurality of spaced supporting legs extending downwardly from each side wall for ~upporting said latticed bottom member above a floor surface and the lik~, wherein supporting legs mounted on one side wall are asymmetrically di~posed relative to further supporting legs mounted on a further, parallel i~ a~tandlt~ side wall;
each side wall further including outwardly extending support protrusions aach vertically aligned with a supporting leg mounted on said respective side wall, each protrusion having a substantially flat upper surface facing away from said bottom member for supporting a supporting leg of a further crate assembly piled on said crate assembly; and hinge means ~oining at least one of said end walls to said latticed bottom ma~ber for pivoting said at least one end wall to a position extending substantially parallel to said latticed bottom member to facilitate loading and ', ,': : :

The invention is illustrated further by the following drawings wherein:
Figure 1 shows a top view of a substratum and transportation crate for plants formed according to the invention;
Figure 2 shows a side view of a longer side of the crate according to Figure l;
Figure 3 shows a front view of one end of the crate according to Figure 1;
Figure 4 shows a side view of two crates according to Figure 1, piled one upon another so that the base blocks are interlocking;
Figure 5 shows a side view of two crates according to Figure 1, piled one upon another so that the base blocks will match one upon another;
Figure 6 shows an enlarged, partial section along the line A-A in Figure 1 from a side part of the crate;
Figure 7 shows a side view of a partial section of a hinged end; and Figure 8 is a perspective view of another embodiment of a crate for plants according to the invention.
The substratum crate, shown in the drawings according to the invention, is manufactured most advantageously of some suitable moisture-and corrosion-proof, weather-resistant plastic raw material by a known method per se, either by die-casting or moulding, preferably in parts to be assembled to form the crate in question.
According to this invention the crate is rectangular in shape and consists of a lattice bottom 1, longer vertical sides 3 and hinged shorter vertical sides 7, the free level of ~he bottom 1 consists of a dense lattice construction, rihs of which intersect each other at an approximately 45 angle. The ribs are spaced approximately 15-20 mm apart and in height are approximately 25 mm. The free bottom space can be about 650 x 1200 mm.
Extending vertically along each lower edge of the bottom longer sides 3 are six leg piaces or base blocks 2' attached to the sides at equal intervals, the leg pieces being preferably part of the lattice bottom, and reaching approximately 80-100 mm below the lower edge of the bottom. They have a rectangular cross-sectional shape and are slightly tapered downwardly, partly in order to ensure easier attachment of the part in demoulding and partly to improve the piling of crates as described further on. The leg pieces 2' are placed about as much as 1/2 of a division, asymmetrically along the sides, also for piling.
The longer sides 3, approximately 80 mm of height, are separately formed and attached to the edge of bottom 1 above the mentioned base blocks 2'. At the point of the base blocks 2' in the sides 3 there are protrusions 2 , corresponding to the shape of the base blocks 2' and tapering correspondingly slightly upward. The upper surface of these protrusions 2 is straight and flat in order to give a suppor~ing surface to the base blocks 2' while the substratum crates are piled high one upon another (Figure 5~. The upper edge of each side 3 reaches somewhat above the upper surface of ~he protrusion 2 , so ehat this upper edge creates a side support for the base blocks 2' of the top crate during piling. Between the protrusions 2 there will remain lntermediate spaces 4, which are bordered by the wall parts of the protru~ions 2 facing each other and also by the bottom surface parts of the crate between these wall parts. Into these intermediate spaces 4 the blocks 2' of the top crate fit during dense piling. When the crates are turned horlzontally 180 with respect to each other, the ends of the crates are squared (Figure 4).
On the lower surface of two base blocks 2' are dents 5 and correspondingly on the upper surfaces of the protrusion 2 above them there are moulding beads or fillers 6. The beads or fillers 6 of one crate are adapted for insertion into corresponding dents 5 of a further crate stacked thereon. Since the upper edges of sides 3 are slightly higher than the surfaces of protrusions 2 , ! ~ , .
,'' '.' . "', '' .

sides 3 support the crate legs 2', so that the legs 2' remain stable even in a high pile. When the piling is dense and in layers the stability is even better, since the legs 2' are interlocked rather deeply.
According to the invention the short sides or ends 7 are hinged at the crate edges so that the same can be opened and folded out- or downwards (Flgure 2). Into the end 7 of the bottom part 1 protruding ~uts 8 are formed, with each ~ut 8 defining a partly open bearing hole 9. At the lower edge of the end 7 there are respective dents and in these a fulcrum pin 10, the same of which fits into the bearing hole 9, with the top part of the aperture being slightly resilient, allowing the pin to snap into its position, and allowing the end 7 to be easily removed, if necessary. The upper edge of side 7 can be also removed, locked to the side 3, by protruding ~uts 11 formed on the upper cdga~ ln the folding end 7, which ~uts 11 flexibly catch between notches 12 ~rmed on the edge of sides 3. The hinged end 7 facilitates the removal of plants from the crates for instance during mechanical unloading.
The bottom of the structure is latticed to save raw material and to make lt light-weight. In addition, the latticed bottom permits air to contact the contQnt~ of the crate. Also, the sides of the crates, not shown in the figures ~r~ preferably latticed. The base blocks 2', related to the bottom structure 2d ~ w~ll a9 the ~ides 3 with their protrusions, are of a hollow structure widely ~ad in plastic techniques. The base blocks 2' are suitably braced to be solid and rigid by the supporting ribs (Figure 6).
The embodiment of the crate according to Figure 8 differs from the embodiment in Figures 1-7 only in manufacturing details aDd appearance. The basic concept of the invention can clearly be recognized in the embodiment in Flgure 8.
The method of production of the crate in Figure 8 differs from the first e~bodiment in that the lattice bottom 1, leg pieces 2' and sides 3, : :, ', ~, .~:
.:: , ~: .. .
: ,' ' ' protrusions 2 are all made in one piece by die-casting or moulding, and whereby the leg pieces 2' and protrusions 2 have a hollow structure. The upper surfaces 13 of the protrusions 2 which take the leg pieces 2' of the upper crate when piling the crates, is a plate 13 whlch is made separately and pushed inside the protrusions 2 to such depth that the upper part of the protrusions 2 forms the edge 14 to take and to lock the lower part of the leg piece 2' when piling the crates. The inner dimensions of the edge 14 as well as its sectional form correspond to the dimensions and form of the lower part of the leg piece 2', e.g. are quadratangular so that the leg pieces can fit a little inside the protrusions 2 between the edge 14. Inside the protrusions a flange has been arranged to take the plate 13.
The outer surface of each protrusion 2 has two vertical grooves 15 to make the construction rigid. The end walls or, at least one of them, are hinged to be folded downwards, with the hinged walls being made of separate parts. The ribs of the bottom lattice face each other perpendicularly and extend parallel or perpendicula~ with regard to the sides of the crate. This embodiment has five protrusions 2 and correspondlngly five leg pieces 2' per ~ide 3.
This embodiment has the same features as the first embodiment as far as the use of the crate is concerned. The legs are attached to the side at equal intervals, similarly the legs are placed longitudinally asymmetric in regard to the sides to allow the same piling possibilitles.
By employing the base block leg construction of the substra~um crate formed according to the invention many special, technical advantages are achieved. Due to the use of several, separate legs the weight (even 400 kg) caused by the crate load, is divided equally and favourably to provide a lasting crate. During storing and transportation it is possible to stack/pile at least 5-6 layers of these crates, filled with plants, whereby the lowest .~ s . . .

crate is strained by loads up to 2000 kg, when it is of importance that the counter-surfaces, bearing the load of the legs, are sufficiently large and plane. Due to the fact that separate and uniform straight supporting sides are used, the advantages of entering the substratum is obtained, and also it is possible to pile as well as interlock one crate upon another. The piling i9 very stable and sturdy during transportation. In order to further secure the piled crates, it is possible to use additional fastenings or ties.
The substratum crate according to the invention, creates a considerable improvement particularly during the handling of plants for forest planting, compared to the previously used contrivances.
By employing the substratum cra~es formed according to the invention, plants can be handled and transported in piles of at least 5 crates at the time, thus considerably shortening working time. The hoisting and transport can be performed by a truck. The transport of empty crates is very easy, since they are light in weight and can be piled densely and staggered.
Due to the plaqtic construction, the crate is also very resistant to diffarent corrosion effects, caused by moisture, weather, soil and vital ~unctions of the plants.

Further, economic mechanical hoisting equipment can be used during the handling and transportation e.g. a truc~ etc. The present transport stage or substratum crate for plants can be piled upon another such crate as securely as possible so that the strain of piling is divided favoursbly, with the result that the cases/crates endure heavy loads.

The invention is illustrated further by the following drawings wherein:

Figure 3 shows a front view of one end of the crate according to Figure 1;

Figure 7 shows a side view of a partial section of a hinged end; and Figure 8 is a perspective view of another embodiment of a crate for plants according to the invention.
The substratum crate, shown in the drawings according to the invention, is manufactured most advantageously of some suitable moisture-and corrosion-proof, weather-resistant plastic raw material by a known method per se, either by die-casting or moulding, preferably in parts to be assembled to form the crate in question.
According to this invention the crate is rectangular in shape and consists of a lattice bottom 1, longer vertical sides 3 and hinged shorter vertical sides 7, the free level of ~he bottom 1 consists of a dense lattice construction, rihs of which intersect each other at an approximately 45 angle. The ribs are spaced approximately 15-20 mm apart and in height are approximately 25 mm. The free bottom space can be about 650 x 1200 mm.
Extending vertically along each lower edge of the bottom longer sides 3 are six leg piaces or base blocks 2' attached to the sides at equal intervals, the leg pieces being preferably part of the lattice bottom, and reaching approximately 80-100 mm below the lower edge of the bottom. They have a rectangular cross-sectional shape and are slightly tapered downwardly, partly in order to ensure easier attachment of the part in demoulding and partly to improve the piling of crates as described further on. The leg pieces 2' are placed about as much as 1/2 of a division, asymmetrically along the sides, also for piling.
The longer sides 3, approximately 80 mm of height, are separately formed and attached to the edge of bottom 1 above the mentioned base blocks 2'. At the point of the base blocks 2' in the sides 3 there are protrusions 2 , corresponding to the shape of the base blocks 2' and tapering correspondingly slightly upward. The upper surface of these protrusions 2 is straight and flat in order to give a suppor~ing surface to the base blocks 2' while the substratum crates are piled high one upon another (Figure 5~. The upper edge of each side 3 reaches somewhat above the upper surface of ~he protrusion 2 , so ehat this upper edge creates a side support for the base blocks 2' of the top crate during piling. Between the protrusions 2 there will remain lntermediate spaces 4, which are bordered by the wall parts of the protru~ions 2 facing each other and also by the bottom surface parts of the crate between these wall parts. Into these intermediate spaces 4 the blocks 2' of the top crate fit during dense piling. When the crates are turned horlzontally 180 with respect to each other, the ends of the crates are squared (Figure 4).
On the lower surface of two base blocks 2' are dents 5 and correspondingly on the upper surfaces of the protrusion 2 above them there are moulding beads or fillers 6. The beads or fillers 6 of one crate are adapted for insertion into corresponding dents 5 of a further crate stacked thereon. Since the upper edges of sides 3 are slightly higher than the surfaces of protrusions 2 , ! ~ , .

sides 3 support the crate legs 2', so that the legs 2' remain stable even in a high pile. When the piling is dense and in layers the stability is even better, since the legs 2' are interlocked rather deeply.
According to the invention the short sides or ends 7 are hinged at the crate edges so that the same can be opened and folded out- or downwards (Flgure 2). Into the end 7 of the bottom part 1 protruding ~uts 8 are formed, with each ~ut 8 defining a partly open bearing hole 9. At the lower edge of the end 7 there are respective dents and in these a fulcrum pin 10, the same of which fits into the bearing hole 9, with the top part of the aperture being slightly resilient, allowing the pin to snap into its position, and allowing the end 7 to be easily removed, if necessary. The upper edge of side 7 can be also removed, locked to the side 3, by protruding ~uts 11 formed on the upper cdga~ ln the folding end 7, which ~uts 11 flexibly catch between notches 12 ~rmed on the edge of sides 3. The hinged end 7 facilitates the removal of plants from the crates for instance during mechanical unloading.
The bottom of the structure is latticed to save raw material and to make lt light-weight. In addition, the latticed bottom permits air to contact the contQnt~ of the crate. Also, the sides of the crates, not shown in the figures ~r~ preferably latticed.

The inner dimensions of the edge 14 as well as its sectional form correspond to the dimensions and form of the lower part of the leg piece 2', e.g. are quadratangular so that the leg pieces can fit a little inside the protrusions 2 between the edge 14. Inside the protrusions a flange has been arranged to take the plate 13.
The outer surface of each protrusion 2 has two vertical grooves 15 to make the construction rigid. The end walls or, at least one of them, are hinged to be folded downwards, with the hinged walls being made of separate parts. The ribs of the bottom lattice face each other perpendicularly and extend parallel or perpendicula~ with regard to the sides of the crate.

Due to the plaqtic construction, the crate is also very resistant to diffarent corrosion effects, caused by moisture, weather, soil and vital ~unctions of the plants.
The dimensions and shape of the substratum crate according to the
2~ lnvention can, of course, deviate from the above description. The shape of the crate sides can be made so that the crates can be placed also side by side in somewhat staggered arrangement. In such a case dents are made in the parts between the base blocks, when the side parts of the ad~acently placed crates are partly staggered, so the base blocks fit into the base block dents of the ad~scent crate. The advantage of this is that on the same surface area more crates can be placed.
