Description

Technical Field

[0001] The present invention relates to a young tree protector for protecting young trees from damage by wild animals such as deer, rabbits, and field mice.

Background Art

[0002] Conventionally, various protectors have been disclosed for protecting planted young trees from damage by wild animals such as deer, rabbits, and field mice (see, for example, Patent Documents 1 to 4). Patent Document 1 discloses a protector for seedlings and the like, comprising a rod-shaped support column, an annular member detachable from one end of the support column, a protective net attached to the annular member, having a mesh and having a vertically long cylindrical or frustum-shaped cone shape, covering the support column, and a locking member fitted to the support column for locking the support column and the protective net. According to the protector for seedlings and the like disclosed in Patent Document 1, when installing on seedlings and the like, it can be attached more simply when attaching the protective net and the annular member to the support column, and even when installing on a plurality of seedlings and the like, the time required for installation can be significantly shortened.

[0003] Further, Patent Document 2 discloses a tree protector characterized in that engaging protrusions are arranged in a staggered pattern on both side edges of a protector body made of a transparent or translucent resin sheet, the center of a locking notch provided at the base of the engaging protrusion is arranged deeper than the intersection of the outer peripheral edge of the protector body and the outer peripheral edge of the engaging protrusion, and the locking notch of one engaging protrusion is locked to the locking notch of the other engaging protrusion. According to the tree protector disclosed in Patent Document 2, the manufacturing cost can be reduced, the assembly work at the site is easy, and the durability is improved.

[0004] Furthermore, Patent Document 3 discloses a mesh tube for preventing animal damage, characterized in that a rectangular mesh tube made of synthetic resin is provided with non-rigid, deformable and easily restored vertical strips made of synthetic resin having an L-shaped cross-section at the four corners. According to the mesh tube for preventing animal damage disclosed in Patent Document 3, a large number of mesh tubes for preventing animal damage can be stacked in a flattened state and transported to the site at once. When installing the mesh tubes for preventing animal damage around young trees at the site, the shape of the vertical strips at the four corners of the mesh tube can be slightly adjusted by hand, and all four vertical strips will return to their original L-shaped cross-section, thus easily restoring the mesh tube to its original rectangular shape.

[0005] Furthermore, Patent Document 4 discloses a cylindrical covering for seedlings, which is made by sewing, fusing, or bonding a polyester or polyolefin fiber cloth or nonwoven fabric that is breathable and has a light transmittance of 50% or more into a tubular shape, with a thickness and shape that is a truncated cone or a cylinder that is easy to put seedlings in, and a height of 100 to 180 cm, wherein the cylindrical covering is fixed to a support in a straight line from the base to the tip of the cylinder, and the support is a rod that is flexible throughout or at the tip.According to the cylindrical covering for seedlings disclosed in Patent Document 4, it has a durability of more than 3 years under natural outdoor conditions, and can protect seedlings from damage caused by herbivores. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Patent No. 6344571 [Patent Document 2] Patent No. 5773428 [Patent Document 3] Patent No. 4199083 [Patent Document 4] Patent No. 3548956 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] It is believed that the seedling protection devices disclosed in Patent Documents 1 to 4 can protect young trees from damage caused by wild animals, etc.

[0008] However, since the installation of these devices on each young tree planted in the forest is done manually, there is a need for young tree protectors that are easy to transport to the installation site and easy to install. The seedling protectors disclosed in Patent Documents 1 to 4 are all thought to be easy to transport to the installation site, but the young tree protector disclosed in Patent Document 1 and the cylindrical covering protector disclosed in Patent Document 4 need to be formed into a cylinder to cover the young tree, and the tree protector disclosed in Patent Document 2 also requires assembly into a cylinder, which is thought to be time-consuming.

[0009] Furthermore, while the tree protector disclosed in Patent Document 2 is reusable, it requires retrieval. This retrieval process is very labor-intensive and incurs labor costs, which could ultimately lead to higher costs.

[0010] Furthermore, in order to eliminate the need for collection work, the seedling protection device described in Patent Document 1 and the insect-repellent mesh tube disclosed in Patent Document 3 disclose the use of biodegradable resin as a component, but the use of biodegradable resin also leads to increased costs.

[0011] Furthermore, in the case of the tree protector disclosed in Patent Document 2, it is difficult to ensure ventilation, and broad-leaved trees may wither and die in the summer. In this respect, the seedling protector disclosed in Patent Document 1 and the mesh tube for preventing animal damage disclosed in Patent Document 3 cover young trees with a net, so it is thought that ventilation is sufficiently ensured. However, if branches that grow during the growth process of young trees get caught in the net, there is a risk that the tree will grow in a bent position due to being pulled by the caught branch.

[0012] Therefore, in view of the above-mentioned problems, the inventors of this invention have diligently studied and developed a young tree protection device that can protect young trees from wild animals without hindering their growth, is easy to transport to the installation site, is very easy to install, is low-cost, and does not require retrieval. As a result, they have arrived at the present invention. [Means for solving the problem]

[0013] In other words, the young tree protector of the present invention comprises a support post erected near the young tree and a clamping member formed by placing a pair of long, plate-like sections opposite each other, and is characterized in that it is installed with the young tree and the support post sandwiched between the pair of plate-like sections, with the tip of the young tree exposed.

[0014] Furthermore, the young tree protection device of the present invention is characterized in that the clamping member is formed by joining one of the long sides of each of the plate-like parts in advance, or by folding one plate-like member in half to place the pair of plate-like parts facing each other.

[0015] Furthermore, the young tree protection device of the present invention is characterized in that the plate-like portion is made of coconut fiber.

[0016] Furthermore, the method for protecting young trees according to the present invention is characterized by erecting a support post near the young tree, and sandwiching the young tree and the support post between a pair of long plate-like parts of a clamping member, with the tip of the young tree exposed, and joining the pair of plate-like parts.

[0017] Furthermore, in the method for protecting young trees of the present invention, the long sides of one of each pair of plate-like parts relating to the clamping member are joined together in advance, the young tree and the support post are sandwiched between the pair of plate-like parts, and then the long sides of the other of each pair of plate-like parts are joined together. [Effects of the Invention]

[0018] According to the young tree protector and the young tree protection method of the present invention, young trees can be easily protected from damage by wild animals and the like. In particular, since the young tree protector of the present invention is mainly composed of a support column and a clamping member, it is convenient to transport to the installation location. Further, the young tree protector and the young tree protection method of the present invention can be installed by sandwiching the young tree and the support column between a pair of plate-like portions related to the clamping member with the tip portion of the young tree exposed, without requiring an assembly operation, and the installation operation is also very easy, and it does not hinder the growth of the young tree.

[0019] Further, in the young tree protector of the present invention, if the clamping member is formed by previously joining one long side of each plate-like portion to each other, it is possible to further facilitate the installation operation at the installation location. Furthermore, even in the mode of forming the clamping member by folding one plate-like member in half, if the clamping member is formed by folding it in half in advance, the installation operation is easy, and even when forming the clamping member at the installation location, since it only requires folding one plate-like member in half, it hardly takes time and effort.

[0020] Further, in the young tree protector of the present invention, when the plate-like portion is made of coconut fiber, it is possible to reduce the weight of the clamping member and provide a low-cost young tree protector that eliminates the need for recovery work after installation.

Modes for Carrying Out the Invention

[0022] Hereinafter, embodiments of the young tree protector of the present invention will be described in detail with reference to the drawings. Figure 1 is a schematic diagram showing the young tree protector 10 according to one embodiment of the present invention installed on a young tree T, Figure 2 is a perspective view showing the clamping member 16 of the young tree protector 10 according to one embodiment of the present invention in a closed state, Figure 3 is a perspective view showing the clamping member 16 of this embodiment in an open state, and Figure 4 is a schematic diagram showing the installation procedure of the young tree protector 10 according to one embodiment of the present invention.

[0023] The young tree protector 10 of this embodiment is composed of a support post 12 erected near the young tree T and a clamping member 16 formed by a pair of long plate-like parts 14, 14 facing each other.

[0024] The support post 12 of the young tree protector 10 of this embodiment is erected near the young tree T and has the function of supporting the clamping member 16, which will be described later. The support post 12 is erected by inserting it directly into the ground, but the insertion depth, the diameter of the support post 12, and the height of the support post 12 from the ground are not particularly limited as long as it can support the clamping member 16. The material of the support post 12 is also not particularly limited, but for example, by using biodegradable resin, the recovery work of the support post 12 can be made unnecessary. However, since the use of biodegradable resin is costly, by using other materials such as iron or wood such as bamboo, a support post 12 that does not require recovery can be provided at a low cost.

[0025] The clamping member 16 of the young tree protector 10 of this embodiment is formed by placing a pair of long plate-like sections 14, 14 opposite each other. In particular, the clamping member 16 of this embodiment is formed by placing a pair of rectangular plate-like sections 14, 14 opposite each other and joining one of the long sides 14a of each plate-like section 14, 14 in advance. Since the other long sides 14b located on the opposite side of the joint 15 are not joined, it is possible to open the pair of plate-like sections 14, 14 around the joint 15, as shown in Figure 3.

[0026] In this embodiment, the pair of plate-like portions 14, 14 that form the clamping member 16 are joined together by staples on one of their long sides 14a. However, the method of joining the pair of plate-like portions 14, 14 is not limited to joining with staples; they may also be joined by sewing or adhesive.

[0027] Furthermore, the material of the pair of plate-like parts 14, 14 that form the clamping member 16 of this embodiment is not particularly limited, but it is preferable that they be made of coconut fiber. In particular, by applying a material made of coconut fiber that is used in the landscaping field and for the support parts of street trees and is generally called "cedar tape," it is possible to provide a clamping member 16 that has appropriate strength, good breathability, is lightweight, easy to process, is low cost, and does not require recycling.

[0028] The young tree protector 10 of this embodiment is mainly composed of the support post 12 and clamping member 16 described above, and can protect young trees T by installing it in the following procedure. Figure 4 shows the installation procedure of the young tree protector 10 of this embodiment, i.e., the method for protecting young trees. First, as shown in Figure 4(a), the support post 12 is erected near the planted young tree T, especially near the trunk of the young tree T.

[0029] Next, as shown in Figure 4(b), the clamping member 16 of the young tree protector 10 of this embodiment is opened, and the young tree T and the support post 12 are sandwiched between the pair of plate-like parts 14, 14. In this embodiment, the clamping member 16 has one long side 14a of the pair of plate-like parts 14, 14 joined together in advance by staples, so at the installation site, the young tree T and the support post 12 can be easily sandwiched by simply opening the pair of plate-like parts 14, 14 around the joint 15 of the pair of plate-like parts 14, 14.

[0030] Furthermore, when the young tree T and the support post 12 are clamped by the clamping member 16 of this embodiment, the tip X of the young tree T protrudes upward from the upper end of the clamping member 16, that is, the tip X is exposed from the clamping member 16. In other words, the lengths of the pair of plate-like parts 14, 14 related to the clamping member 16 are adjusted in advance so that the tip X of the young tree T is exposed from the clamping member 16. The height of the young tree T to which the young tree protector 10 of this embodiment is applied is approximately 70 cm to 100 cm, and the length in the longitudinal direction of the plate-like part 14 is adjusted so that the tip X of the young tree T is exposed by about 10 cm to 15 cm. The young tree protector 10 of this embodiment is primarily intended to protect against damage caused by wild animals, especially wild rabbits.

[0031] Then, as shown in Figures 4(c) to 4(f), by joining the other long sides 14b of the pair of plate-like parts 14, 14, the clamping member 16 is installed with the young tree T and the support post 12 sandwiched between the pair of plate-like parts 14, 14 of the clamping member 16. In this embodiment, wire is used as the fastener 18 to join the other long sides 14b, but for example, staples, clips, or adhesives may be used for joining. Furthermore, the joining position and number of joining points are not particularly limited and can be appropriately selected according to the length of the pair of plate-like parts 14, 14 of the clamping member 16.

[0032] As described above, with the young tree protector 10 and young tree protection method of this embodiment, the young tree T is held by the clamping member 16, so the young tree T can be easily protected from damage caused by wild animals, especially wild rabbits. In particular, since the young tree protector 10 of this embodiment is mainly composed of a support post 12 and a clamping member 16, it is easy to transport to the installation site. Furthermore, the young tree protector 10 and young tree protection method of this embodiment can be installed by clamping the young tree T and the support post 12 between a pair of plate-like parts 14, 14 of the clamping member 16 with the tip X of the young tree T exposed, so no assembly work is required and the installation work is very easy. Moreover, since the young tree T is held by the clamping member 16 with the tip X of the young tree T exposed, the growth of the young tree T is not hindered.

[0033] Furthermore, in the young tree protection device 10 of this embodiment, the clamping member 16 is formed by pre-joining one of the long sides 14a of each plate-like portion 14, 14 together, which further facilitates the installation work at the installation site.

[0034] Furthermore, in the young tree protector 10 of this embodiment, by forming the support post 12 from wire or wood, and forming the pair of plate-like parts 14, 14 related to the clamping member 16 from coconut fiber, the clamping member 16 can be made lighter, and the young tree protector 10 can be provided at a low cost, as it has good ventilation and does not require retrieval work after installation.

[0035] Although the young tree protection device of the present invention has been described in detail above, the embodiments described above should not be interpreted as substantially limiting the technical idea of ​​the present invention. For example, the clamping member of the young tree protection device of the present invention may be formed by folding a plate-shaped member in half to create a pair of opposing plate-shaped parts. In the embodiment in which the clamping member is formed by folding a plate-shaped member in half, the installation work is easy if the clamping member is formed in advance by folding it in half, and even when the clamping member is formed at the installation site, it can be easily formed by simply folding a plate-shaped member in half, thus requiring almost no effort. The present invention can be implemented with appropriate improvements, modifications, or additions by those skilled in the art, without departing from its gist. [Explanation of symbols]
