Description

[Technical Field]

[0001] The present invention relates to a young tree protector that protects young trees from damage caused by wild animals. [Background technology]

[0002] Various types of protectors have been disclosed for protecting planted young trees from damage caused by wild animals such as deer, hares, and field mice (see, for example, Patent Documents 1 to 4). Patent Document 1 discloses a protector for seedlings, etc., which comprises a rod-shaped support, a ring-shaped member that can be attached and detached to one end of the support, a protective net that is attached to the ring-shaped member and has a meshed, elongated cylindrical or truncated cone shape and covers the support, and a locking member that fits onto the support and locks the support and the protective net. Patent Document 1 describes that the protector for seedlings, etc., disclosed in this patent document, can be easily attached to seedlings, etc. when the protective net and ring-shaped member are attached to the support, and that the time required for installation can be significantly reduced even when multiple seedlings, etc. are to be installed.

[0003] Patent Document 2 discloses a tree protector in which engaging protrusions are arranged in a staggered pattern on both side edges of a protector body made of a transparent or translucent resin sheet, and the centers of locking notches provided at the bases of the engaging protrusions are located further back than the intersection of the outer periphery of the protector body and the outer periphery of the engaging protrusions, and the locking notches of one engaging protrusion lock into the locking notches of another engaging protrusion. It is stated that the tree protector disclosed in Patent Document 2 can reduce manufacturing costs, facilitate on-site assembly, and improve durability.

[0004] Furthermore, Patent Document 3 discloses a net cylinder for preventing animal damage, characterized in that vertical strips made of non-rigid synthetic resin with an L-shaped cross section that can be freely deformed and restored are provided at the four corners of a rectangular net cylinder made of synthetic resin net. The document states that with the net cylinder for preventing animal damage disclosed in Patent Document 3, many net cylinders for preventing animal damage can be stacked in a spread-out, approximately flat state and transported to the site in large quantities at once, and that when the net cylinders for preventing animal damage are installed around young trees at the site, all four vertical strips can be restored to their original L-shaped cross section simply by slightly adjusting the shape of the vertical strips at the four corners of the net cylinder, so that the net cylinder for preventing animal damage can be easily restored to its original rectangular tubular shape.

[0005] Patent Document 4 discloses a cylindrical object for covering and protecting seedlings, which is made by sewing, fusing, or bonding breathable polyester or polyolefin fiber cloth or nonwoven fabric having a light transmittance of 50% or more into a cylindrical shape, and which has a diameter and shape of a truncated cone or a cylinder that easily accommodates seedlings, and is 100 to 180 cm high, and which is characterized in that the cylindrical object is fixed to a support in a straight line from the base to the tip, and the support is a rod that is flexible throughout the entire support or at the tip.The document also discloses that the cylindrical object for covering and protecting seedlings can be durable for more than three years under natural outdoor conditions, and can therefore protect seedlings from damage 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 Summary of the Invention [Problem to be solved by the invention]

[0007] It is believed that the protective devices for seedlings and the like disclosed in Patent Documents 1 to 4 can protect young trees from damage caused by wild animals.

[0008] However, because the installation work on each young tree planted in a forest is done manually, there is a demand for a young tree protector that can be easily transported to the installation site and installed. The sapling 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 and protection object disclosed in Patent Document 4 must be formed into a cylindrical shape to cover the young tree, and the tree protector disclosed in Patent Document 2 also requires the work of assembling it into a cylindrical shape, which is thought to be time-consuming.

[0009] Furthermore, while the tree protector disclosed in Patent Document 2 is reusable, it does require collection work, which is extremely labor-intensive and requires labor costs, potentially resulting in higher costs.

[0010] Furthermore, in order to eliminate the need for collection work, the protective equipment for seedlings, etc. disclosed in Patent Document 1 and the mesh cylinder for preventing animal damage disclosed in Patent Document 3 disclose the use of biodegradable resins in their constituent parts, but the use of biodegradable resins also leads to higher costs.

[0011] Furthermore, with a tree protector such as that disclosed in Patent Document 2, it is difficult to ensure ventilation, and there is a risk that broad-leaved trees may wither in the summer. In this regard, the seedling protector disclosed in Patent Document 1 and the animal damage prevention net cylinder disclosed in Patent Document 3 cover young trees with netting, and so are thought to ensure sufficient ventilation, but if a branch that grows during the young tree's growth process gets caught in the net, there is a risk that the young tree will be pulled by the caught branch and grow in a bent, diagonal position.

[0012] In view of the above problems, the inventors of the present application conducted extensive research to provide a young tree protector that can protect young trees from wild animals without interfering with their growth, is easy to transport to the installation site, is very easy to install, is low-cost, and does not require recovery work. As a result, they arrived at the present invention. [Means for solving the problem]

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

[0014] Furthermore, in the young tree protector of the present invention, the clamping member is characterized in that it is formed by previously joining one long side of each of the plate-shaped portions together, or by folding one plate-shaped member in half and placing the pair of plate-shaped portions opposite each other.

[0015] Furthermore, in the young tree protector of the present invention, the plate-shaped portion is made of palm fiber.

[0016] In addition, the method for protecting young trees of the present invention is characterized in that a support is erected near the young tree, and the young tree and the support are sandwiched between a pair of long plate-shaped portions of a clamping member formed with the pair of plate-shaped portions facing each other, with the tip of the young tree exposed, and the pair of plate-shaped portions are joined.

[0017] Furthermore, in the method for protecting young trees of the present invention, one of the long sides of each pair of plate-shaped portions of the clamping member is joined together in advance, and after the young tree and the support are sandwiched between the pair of plate-shaped portions, the other long sides of each pair of plate-shaped portions are joined together. [Effects of the Invention]

[0018] The young tree protector and method of protecting young trees of the present invention can easily protect young trees from damage caused by wild animals. In particular, because the young tree protector of the present invention is mainly composed of a support and a clamping member, it is easy to transport to the installation site. Furthermore, the young tree protector and method of protecting young trees of the present invention can be installed by sandwiching the young tree and support between a pair of plate-like members of the clamping member with the tip of the young tree exposed. This does not require assembly work, makes installation very easy, and does not interfere with the growth of the young tree.

[0019] Furthermore, in the young tree protector of the present invention, if the clamping members are formed by joining one long side of each plate-shaped portion together in advance, installation at the installation site can be further facilitated. Furthermore, even in an embodiment in which the clamping members are formed by folding one plate-shaped member in half, if the clamping member is formed by folding it in half in advance, installation is easy, and even when the clamping member is formed at the installation site, it only requires folding one plate-shaped member in half, so it requires almost no effort.

[0020] In addition, in the young tree protector of the present invention, the plate-shaped portion is made of palm fiber, which makes the clamping member lighter and eliminates the need for retrieval work after installation, making it possible to provide a young tree protector at low cost.

DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, an embodiment of the young tree protector of the present invention will be described in detail with reference to the drawings. Figure 1 is a schematic explanatory diagram showing a 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 a 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 a clamping member 16 of this embodiment in an open state, and Figure 4 is a schematic explanatory diagram showing the installation procedure for 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 12 erected near the young tree T, and a clamping member 16 formed by a pair of long plate-shaped portions 14, 14 facing each other.

[0024] The support 12 of the young tree protector 10 of this embodiment is erected near the young tree T and functions to support the clamping member 16, which will be described later. The support 12 is erected by directly inserting it into the ground, and there are no particular restrictions on the insertion depth, diameter of the support 12, or height of the support 12 from the ground, as long as it can support the clamping member 16. The material of the support 12 is also not particularly limited, and for example, biodegradable resin can be used to eliminate the need to recover the support 12. However, since the use of biodegradable resin is costly, other materials, such as iron or wood such as bamboo, can be used to provide a low-cost support 12 that does not require recovery.

[0025] The clamping member 16 of the young tree protector 10 of this embodiment is formed by opposing a pair of long plate-like portions 14, 14. In particular, the clamping member 16 of this embodiment is formed by opposing a pair of rectangular plate-like portions 14, 14 in front view, and then joining one long side 14a of each plate-like portion 14, 14 together in advance. Note that the other long sides 14b located on the opposite side of the joint 15 are not joined together, so that the pair of plate-like portions 14, 14 can be opened around the joint 15, as shown in Figure 3.

[0026] Here, the pair of plate-like portions 14, 14 forming the clamping member 16 of this embodiment are joined together at one of their long sides 14a with a stapler. Note that the method for joining the pair of plate-like portions 14, 14 is not limited to joining with a stapler, and they may also be joined by sewing or with an adhesive.

[0027] The material of the pair of plate-like portions 14, 14 that form the clamping member 16 of this embodiment is not particularly limited, but is preferably made of palm fiber. In particular, by using a material made of palm fiber that is commonly called "cedar tape" and is used in landscaping and for supporting roadside trees, it is possible to provide a clamping member 16 that has adequate strength, good breathability, is lightweight, is 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 above-mentioned support 12 and clamping member 16, and can protect the young tree T by installing it on the young tree T in the following procedure. Figure 4 shows the installation procedure for the young tree protector 10 of this embodiment, i.e., the young tree protection method. First, as shown in Figure 4(a), the support 12 is erected near the planted young tree T, particularly 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 12 are sandwiched between the pair of plate-like portions 14, 14. The clamping member 16 of this embodiment has one long side 14a of the pair of plate-like portions 14, 14 joined together in advance with a stapler, so that at the installation site, the young tree T and the support 12 can be easily sandwiched by simply opening the pair of plate-like portions 14, 14 around the joint 15 of the pair of plate-like portions 14, 14.

[0030] Furthermore, when the young tree T and the support 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, i.e., the tip X is exposed from the clamping member 16. In other words, the length of the pair of plate-shaped members 14, 14 of the clamping member 16 is 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 longitudinal length of the plate-shaped member 14 is adjusted so that approximately 10 cm to 15 cm of the tip X of the young tree T is exposed. The young tree protector 10 of this embodiment is primarily intended to protect the young tree from damage caused by wild animals, particularly wild rabbits.

[0031] 4(c) to 4(f), by joining the other long sides 14b of the pair of plate-like portions 14, 14 together, the clamping member 16 is installed with the young tree T and the support 12 sandwiched between the pair of plate-like portions 14, 14 of the clamping member 16. In this embodiment, wire is used as the connector 18 to join the other long sides 14b together, but they may also be joined using, for example, a stapler, clips, adhesive, or the like. The joining positions and the number of joints are also not particularly limited and are selected appropriately depending on the length of the pair of plate-like portions 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 clamped by the clamping members 16, which makes it easy to protect the young tree T from damage by wild animals, particularly wild rabbits. In particular, the young tree protector 10 of this embodiment is composed mainly of the support 12 and the clamping members 16, making it 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 12 between a pair of plate-like members 14, 14 of the clamping members 16 with the tip X of the young tree T exposed, which eliminates the need for assembly and makes installation extremely easy. Furthermore, because the tip X of the young tree T is clamped by the clamping members 16 with the exposed tip X, the growth of the young tree T is not hindered.

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

[0034] Furthermore, in the young tree protector 10 of this embodiment, the support 12 is made of wire or wood, and the pair of plate-shaped portions 14, 14 of the clamping member 16 are made of palm fiber, which makes the clamping member 16 lighter, has good breathability, and eliminates the need for removal work after installation, making it possible to provide a young tree protector 10 at low cost.

[0035] Although the young tree protector of the present invention has been described in detail above, the above-described embodiments should not be construed as substantially limiting the technical scope of the present invention. For example, the clamping member of the young tree protector of the present invention may be formed by folding a single plate-shaped member in half and arranging a pair of plate-shaped portions facing each other. In an embodiment in which the clamping member is formed by folding a single plate-shaped member in half, installation is easy if the clamping member is formed by folding it in half in advance. Even when the clamping member is formed at the installation site, it can be easily formed simply by folding the single plate-shaped member in half, requiring little effort. The present invention can be implemented with appropriate improvements, modifications, and additions based on the ingenuity and ingenuity of those skilled in the art without departing from the spirit and scope of the present invention.
