[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention aims to promote the growth of seedlings and planted trees in forests, and to prevent the damage to animals such as deer, rabbits, and rats from being eaten by a polygonal folding type used over seedlings. Related to the tree protector.

[0002]

[Prior art]

 Conventionally, when planting a seedling, 30% of the deer and other animals suffer from animal damage caused by eating new shoots, leaves or stems, or the growth of the weeds that the seedlings regenerate is lost, and cover damage due to lack of light. There was a problem that 90% withered.

[0003] For this reason, recently, a so-called tree protector formed of a translucent resin material in a cylindrical shape is covered from above the seedlings, and is fixed to a splint that has been driven into the ground with a string. In addition, the seedlings are kept at the optimum temperature, and the growth is accelerated by keeping the internal humidity constant (Utility Model Registration No. 3009585).

[0004]

[Problems to be solved by the invention]

 However, since the length of the tree protector is about 150 cm at the maximum, when the seedling grows to a certain extent, it extends outward from the upper end opening. Therefore, there is a problem that the extended portion is not only eaten by a large animal such as a deer, but also the opening end of the tree protector is damaged by a seedling pulled to the side when eating. Was.

In view of the above, an object of the present invention is to make it possible to easily attach a separate extension member to the upper part of the protector body and to increase the height of the tree protector.

[0006]

Means for Solving the Problems In order to solve the above problems, a tree protector of the present invention is a foldable protector in which a transparent or translucent resin sheet is formed into an even-numbered cylindrical body having a rectangular cross section or more. In a tree protector having a main body, a protruding member consisting of a cylindrical body having the same angle as the protector main body and being insertable into the inside of the protector main body from an upper end opening is provided, and the protruding member is attached to an upper portion of the protector main body. This will increase the overall height.

[0007] Alternatively, in a tree protector having a foldable protector body in which a transparent or translucent resin sheet is formed into an even-numbered cylindrical body having a rectangular cross section or more, a tree body having the same angle as the protector body is provided. In addition, a thigh member that can be fitted to the outside of the protector body is provided at the top of the protector body, and the tall member is attached to the top of the protector body to increase the overall height.

[0008] Specifically, as means for maintaining the attached state of the protector main body and the extension member, a folding piece having a locking piece at an edge of each open end of the protector main body and the extension member is provided. The folded piece of the protector body and the folded piece of the extension member are folded back to the facing surfaces, and the facing surfaces of the protector body or the extension member are pressed against each other by the folded pieces in the mounted state.

In addition, a cut-and-raised portion is provided on at least one side of the protector main body and the extension member, and the cut-and-raised portion is locked to the edge of the other open end.

[0010]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the tree protector 10 of the present invention includes a protector body 11 which is the same as the conventional protector, and a foot member 20 attached to an upper portion of the protector body 11. The tree protector 1 is raised by attaching the above-mentioned extension foot member 20 to the upper portion of the protector main body 11 via a predetermined locking means.

As shown in FIG. 3, the protector main body 11 is formed by engraving a notch 13 for refraction on a transparent or translucent resin sheet 12 to form a cylindrical body having a substantially regular hexagonal cross section. It is what it was. As shown in FIG. 4 (A), folded pieces 15 are provided at the edges of the six side portions 14 constituting each side of the opening at both ends. A locking piece 16 is formed at the tip of each folded piece 15. Then, the folded pieces 15 are folded inwardly into the side surface of the resin sheet 12, and are inserted into slits 17 formed on the side surface of the resin sheet 12 to be locked. Note that reference numeral 18 in the drawing denotes a glue substitute piece.

As shown in FIG. 4B, the extension member 20 has a shape obtained by cutting the protector main body 11 into substantially half. Specifically, a notch 22 for refraction is engraved on a transparent or translucent resin sheet 21 to form a cylinder having a substantially regular hexagonal cross section. The width H2 of the side portion 23 formed by the cut portion 22 is set to be slightly smaller than the width H1 of the side portion 14 of the protector main body 11, and is a hexagonal cylindrical shape that can be inserted into the inside of the protector main body 11. I try to make. As in the case of the protector body 11, a folded piece 24 having a locking piece 25 is provided at an edge of a side portion 23 constituting each side of the one-end opening of the extension member 20. The locking pieces 25 of the folded pieces 24 are locked by being inserted into slits 26 formed on the side surface of the resin sheet 21.

In the present embodiment, the folded pieces 15 and 24 of the protector main body 11 and the extension member 20 serve to hold the resin sheets 12 and 21 in a hexagonal cylindrical shape in a tubular state, It functions as locking means for maintaining the attached state of the protector main body 11 and the extension member 20. Examples of resin materials that can be used as the resin sheets 12 and 21 include PP (polypropylene) and PE (polyethylene). However, when using PE, there is no adhesive that can be applied with the current technology, so it is necessary to take measures, for example, with screws.

The manufacture of the protector body 11 is performed as follows. First, as shown in FIG. 3, a long resin sheet 12 (having a thickness of 0.5 to 1.0 mm, preferably 0.7 to 1.0 mm and a width of 1600 mm) wound in a roll shape is moved in one direction. The rollers are stopped at a predetermined position, and slightly cut from the surface with disk-shaped cutting teeth 31 provided on each roller 30 arranged side by side at a predetermined interval, thereby forming six rows of cutting portions 13 in the width direction Y. To form Here, in the resin sheet 12, the longitudinal direction (moving direction) X is the stretching direction when the sheet is formed, and when the cut 13 is formed along the X direction, the completed tree is formed. The strength of the protector 10 decreases. Therefore, in the present embodiment, the cut portion 13 is formed along the width direction Y orthogonal to the stretching direction.

Next, the resin sheet 12 is cut. More specifically, as shown in FIG. 4 (A), the resin sheet 12 is folded back about 6 cm wide so as to correspond to each edge of the side portion 13 divided into six by the cut portion 13. Piece 15, a locking piece 16 extending from the center of the tip of each folded piece 15, and a glue margin piece 18 extending from the edge of the side portion 14 at one end via the cutout 13. Disconnect. Further, a slit 17 is formed in the side portion 14 so that the locking piece 16 is locked in a state where the folding piece 15 is folded.

Subsequently, the cut resin sheet 12 is arranged such that the cut portion 13 is located inside, and an adhesive (for example, cyanoacrylate, epoxy, polystyrene, or polyamide is used). Can be applied). And it is completed by sticking to the edge of the side part 14 on the opposite side. However, the adhesive margin piece 18 may be heat-welded to the opposite side edge.

In the protector body 11 formed as described above, since the number of the cut portions 13 formed in the side portions 14 is an even number, as shown in FIG. The two cuts 13 can be used to fold and stack. As a result, the occupied space can be kept very small, which is suitable for transportation.

In the production of the extension member 20, the side portion 23 formed between the adjacent cut portions 22 has a width of about 5.7 cm, and only one edge of the side portion 23 has the folded piece. 24, the same as the protector main body 11 except that a locking piece 25 and a slit 26 are formed. Further, the length of the side portion 23 of the extension member 20 can be changed as desired.

Next, a method of using the tree protector 10 will be described. First, when a seedling is planted in a mountain or the like, only the protector body 11 is used. That is, as shown in FIG. 5, after being transported to a mountain or the like in a state of being folded in two, the cut-out portion 13 is used to form a substantially hexagonal cross section, and each folded piece 15 is folded inward. By inserting the locking pieces 16 of the folded pieces 15 into the slits 17, the assembly can be easily performed.

Then, the protector main body 11 is covered from above the seedling, and is fixed to a splint (not shown) driven into the ground with a string. Thereby, it is possible to prevent animal damage caused by eating the shoots, leaves or stems of the seedlings by the deer, rabbits, rats and the like. Further, since the sapling is made of translucent resin, the illuminated light is used as scattered light so that the sapling is not overheated, and carbon dioxide generated from the sapling is accumulated inside. This not only provides good heat and moisture retention for the seedlings, but also promotes growth by carbon assimilation.

When the seedlings have grown in this way and the branches and the like have extended from the upper end opening of the protector main body 11, the extension member 20 is attached to the upper part of the protector main body 11. That is, as in the case of the protector main body 11, after being transported to the mountain in a state of being folded in two, the cut-out portion 22 is used to form a substantially hexagonal cross section, and each folded piece 24 is connected to the inner surface of the protector main body 11. Fold outward so that they face each other. Then, by inserting the locking piece 25 of the folded piece 24 into the slit 26, the assembly can be easily performed. In this state, as shown in FIG. 1, the protector main body 11 and the folded pieces 15 and 24 of the extension member 20 face each other and are elastically curved.

Then, as shown in FIG. 1, the extension member 20 is inserted into the protector body 11 attached to the seedling first from the upper end opening, with the folded piece 24 facing downward. Thereby, as shown in FIG. 2, the curved folded pieces 15, 24 press the opposing surfaces of the opposing protector body 11 or the extension member 20. As a result, the foot member 20 can be held on the upper part of the protector body 11 without displacement.

As described above, according to the tree protector 10 of the present invention, the height of the tree protector 10 can be easily changed by simply attaching the extension member 20 to the upper portion of the protector body 11. Therefore, it can be protected from animal damage until the plant is fully grown. As a result, the problem that the open end of the tree protector 10 is damaged by the seedlings pulled to the side when eaten by the animal can be prevented beforehand. When the seedlings have grown sufficiently, the tree protector 10 is removed. Since the removed tree protector 10 is made of PP or the like having no base, even if it is incinerated, it does not emit harmful substances, so it is safe.

FIG. 6 shows a tree protector 10 according to the second embodiment. The tree protector 10 is the same as the first embodiment except that at least two cut-and-raised portions 33 are provided on two opposing sides of the side portion 14 of the protector main body 11.

The tree protector 10 of the second embodiment pushes the cut-and-raised portion 33 inward when the seedling grows and the extension member 20 is attached to the upper part of the protector main body 11. As a result, the cut-and-raised portion 33 is locked and held at the edge of the opening end of the foot member 20. As a result, the attached foot member 20 is prevented from sliding down, and the attached state can be reliably maintained.

The cut-and-raised portion 33 may be provided on the side of the foot member 20 as shown by a broken line in FIG. Then, when attached to the protector main body 11, it may be pushed out from the inside and locked to the open end of the protector main body 11. Furthermore, it may be provided on both the protector body 11 and the extension member 20. In the second embodiment, it is not always necessary to form the folded pieces 15 and 24. And the cut-and-raised part 33 may be provided in all the side parts 14.

FIG. 7 shows a tree protector 10 according to a third embodiment. The tree protector 10 has the cut portions 22 formed so that the width H2 of each side portion 23 of the foot member 20 is slightly larger than the width H1 of the side portion 14 of the protector body 11. For this reason, the protector body 11 is mounted so as to be fitted over the upper part of the protector body 11, and is the same as the first embodiment except for this point. The protector body 11 and / or the extension member 20 of the third embodiment may be provided with a cut-and-raised portion 33 similar to that of the second embodiment.

In the third embodiment, by attaching the extension member 20 so as to cover the upper portion of the protector body 11, the attachment of the protector body 11 and the extension member 20 is performed as in the first embodiment. Can maintain the condition and protect the seedlings.

Note that the tree protector 10 of the present invention is not limited to the configuration of each of the above embodiments. For example, when the protector main body 11 and the extension member 20 are locked, as shown in FIG. 8, through holes 35 and 36 facing the protector main body 11 and the extension member 20, respectively, are provided. The resin rivet 37 may be inserted and locked. Further, as shown in FIG. 9, an annular groove 38 may be provided in the protector main body 11 and a projection 39 may be provided in the extension member 20 so that the attached state may be maintained by engaging these members. Here, the groove 38 and the projection 39 do not necessarily need to be formed in an annular shape, but may be formed by discontinuous concave portions and convex portions. As described above, the locking means between the protector main body 11 and the extension member 20 can be variously changed, and a well-known mounting mechanism can be applied.

A similar mounting structure is formed on the upper part of the extension member 20, and the second extension member 20 is mounted on the upper part of the first extension member 20 already mounted on the upper part of the protector body 11. Can be attached, the height of the tree protector 10 can be further increased.

[0031]

[Effect of the invention]

 As is apparent from the above description, in the tree protector according to the first and second aspects of the present invention, the total height of the tree protector can be increased by attaching the extension member to the upper portion of the protector body. Therefore, even if the planted seedlings grow and the branches, etc., extend from the upper end opening of the protector body that was originally mounted, the plants can grow sufficiently by mounting the tread protector and raising the tree protector. Until then, it can be protected from animal damage.

[0032] Further, according to the third aspect of the present invention, the protector body and the extension member are provided with foldable pieces having locking pieces at the edges of the open ends thereof, and these foldable pieces are folded back to the opposing surfaces, respectively. Alternatively, if the opposing surfaces of the extension member are pressed against each other to maintain the attached state, the lower end of the extension member is simply inserted or externally fitted to the protector body, thereby completing the attaching operation. For this reason, it is easy to work on a foot and is suitable for working on complicated terrain such as mountains.

Further, according to the present invention, a cut-and-raised portion is provided on at least one side of the protector body and the extension member, and the cut-and-raised portion locks the other open end. In addition, there is an effect that it is possible to reliably prevent the extension member from slipping and falling due to the influence of wind, own weight, and the like. As a result, the problem that the open end of the tree protector is damaged by the seedlings pulled to the side when eaten by the animal can be prevented beforehand.
