TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a cover for a growth product suitable for use as a bird and animal harm prevention tool for protecting trees from birds and animals.
[0002]
[Prior art]
In general, the damage caused by wild birds and beasts in forests is remarkably caused mainly by deers, bears, and the like. For this reason, various countermeasures such as protective fences, repellents, explosive sounds, etc. have been taken, but their effects are limited, or considerable cost and labor (work) are forced along with the implementation. It has been pointed out that garbage has a negative impact on the natural environment, and it can be implemented with less cost and labor than before, and it is possible to obtain a sufficient preventive effect against birds and beasts while avoiding a negative impact on the natural environment. Measures were desired.
[0003]
Therefore, the present applicant has already proposed a bird and animal harm prevention tool effective for such a countermeasure in Japanese Patent Application Laid-Open No. 2002-330691. This bird and beast harm prevention device is formed of at least a biodegradable resin in a sheet shape, and a band portion that can be wound at a predetermined position of the tree, and at least formed of a biodegradable resin, and the band portion is formed at a predetermined position of the tree.

[Problems to be solved by the invention]
However, the above-mentioned bird and animal harm prevention tool has the following problems to be solved.
[0005]
First, trees grow over the years, so the bird and animal harm prevention device described above was also provided with a plurality of notches extending in the longitudinal direction in the band, so that the trees could follow the growth of the trees. However, in such a cut portion, there is a limit to the length that can be extended, and eventually, depending on how the tree grows, there is a possibility that the cut portion may come off due to breakage.
[0006]
Secondly, when mounting on a tree, a separate fixing portion for fixing the band portion to a cylindrical shape is required, which leads to an increase in cost due to an increase in the number of parts and a troublesome mounting operation.
[0007]
Third, since only the mode in which the band is wound around the tree, there is room for improvement in simplifying the shape and further enhancing the effect of preventing bird and animal damage.
[0008]
The present invention solves the problems existing in such conventional techniques, and reliably avoids breakage due to the growth of a growth such as a tree, and reduces the number of parts to reduce costs and facilitate mounting work. In addition, it is an object of the present invention to provide a cover for a growth that can further enhance the effect of preventing bird and animal damage.
[0009]
Means and Embodiments for Solving the Problems
The present invention includes a first band portion 2 wound around a growth T when forming the growth covers 1 and 1e to be wound around the growth T, and one end 2s of the first band 2 in the longitudinal direction. And a second band portion 4 having a predetermined length Ld to be inserted into the insertion hole 3 is provided on the other end 2t side of the first band portion 2 in the longitudinal direction, and the width of the second band portion 4 is provided. A plurality of elastic protrusions 5 are provided on the sides 4p and 4q on both sides in the direction at predetermined intervals along the longitudinal direction, and from the tip of the elastic protrusions 5 on one side in the width direction of the second band portion 4. The length Li up to the tip of the elastic protrusions 5 on the other side is selected to be longer than the length Lh of the insertion hole 3 in the width direction. In this case, according to the preferred embodiment, the first band portion 2, the second band portion 4, and the elastic protrusions 5 can be integrally formed by a net member N using an elastic material. Further, the present invention can be applied to a tree as the growth T, and can be applied to a bird and animal harm prevention tool wound around the tree as the growth cover 1 and 1e.
[0010]
Thus, when the growth covers 1 and 1e are wound around the growth T and the second band 4 is inserted into the insertion hole 3, the elastic projections 5 are elastically deformed. Can be inserted through the insertion hole 3. At this time, the elastic projections 5 that have passed through the insertion holes 3 return to elasticity, and the elastic projections 5 that have returned to elasticity are locked to the edges of the insertion holes 3, so that easy removal is prevented, and growth occurs. The article covers 1 and 1e are held in a state of being wound around the growth T. The tip of the second band portion 4 inserted through the insertion hole 3 by attachment is a free end and protrudes from the growth T. On the other hand, when the growth T grows, the diameter of the growth covers 1 and 1e attached to the growth T also increases. At this time, the elastic projections 5 pass through the insertion holes 3 due to elastic deformation, and the diameters of the growth covers 1 and 1e increase. The size of the diameter is arbitrarily set by selecting the length Ld of the second band portion 4 in the longitudinal direction.
[0011]
【Example】
Next, preferred embodiments according to the present invention will be described in detail with reference to the drawings.
[0012]
First, the configuration of the bird / beast harm prevention tool (growth cover) 1 according to the present embodiment will be described with reference to FIGS. 1 to 3.
[0013]
FIG. 2 shows the entire configuration of the bird and animal harm prevention implement 1. The bird and beast harm prevention tool 1 is integrally formed by a net member N using an elastic material. Therefore, at the time of manufacturing, a net material No having a continuous shape having the same width as shown by the imaginary line in FIG. 2 is prepared, and the bird and animal harm prevention tool 1 having the shape shown by the solid line in FIG. As described above, the bird and animal harm prevention implement 1 according to the present embodiment can be manufactured extremely easily.
[0014]
As the mesh material No., an elastic material such as a synthetic resin having a predetermined elasticity is used. In this case, a general synthetic resin may be used, but desirably, a biodegradable resin blended with a light stabilizer for a polymer, for example, a biodegradable resin disclosed in JP-A-2002-330991 or the like is used. Can be used. This type of biodegradable resin has properties equivalent to other general synthetic resins (general-purpose resins) in normal use, but is degraded by water to carbon dioxide by microorganisms in the natural environment such as soil. You. In addition, by adding an appropriate amount of the polymer light stabilizer, the weather resistance is particularly improved.
[0015]
The bird and beast harm prevention device 1 includes a first band portion 2 having a strip shape having a width La (for example, about 20 cm) and a length Lb (for example, about 40 cm). In addition, an insertion hole 3 is provided at one end 2s in the longitudinal direction of the first band portion 2, and a width Lc (for example, inserted into the insertion hole 3) at the other end 2t in the longitudinal direction of the first band portion 2. A second band portion 4 having a length of about 13 cm and a length Ld (for example, about 60 cm) is provided. Further, a plurality of elastic protrusions 5 are provided at predetermined intervals along the longitudinal direction on the sides 4p, 4q on both sides in the width direction of the second band portion 4. In this case, the length Li from the tip of the elastic protrusions 5 on one side to the tip of the elastic protrusions 5 on the other side in the width direction of the second band portion 4 is greater than the length Lh of the insertion hole 3 in the width direction. Is also long, that is, Li> Lh.
[0016]
Such elastic protrusions 5 can be easily provided by selecting a position at which the mesh material No is cut off. Also, when the net material No is cut, by leaving the same protrusions as the elastic protrusions 5 on both sides in the width direction of the first band portion 2, the repelling effect on birds and animals can be enhanced. In addition, 11 is a guide piece provided at the tip of the second band portion 4, whereby the second band portion 4 can be easily inserted into the insertion hole 3. Further, the bird / beast harm prevention device 1 can be given a color having a high repellent effect on birds and beasts, and can be coated (or mixed) with a luminous paint (luminous pigment) or the like as necessary.
[0017]
Next, the method of use and operation of the bird / beast harm prevention tool 1 according to the present embodiment will be described with reference to FIGS.
[0018]
First, the bird and animal harm prevention implement 1 is brought to a tree (growth) T to be mounted. Then, as shown in FIG. 1, a predetermined position Xe of the tree T seen from the bird and animal A, preferably, a height of about 90 [cm] from the ground corresponding to the eye level for a relatively large bird and animal A such as a bear or a deer. Now, the bird and animal harm prevention device 1 is wound, and the second band portion 4 is inserted into the insertion hole 3 as shown in FIG. At the time of insertion, the elastic protruding portions 5 provided on the second band portion 4 abut against the edge of the insertion hole 3, but the elastic protruding portions 5 are elastically deformed. Can be inserted. In FIG. 3, the mesh of the mesh member N is omitted for easy viewing.
[0019]
Then, the second band portion 4 is fastened to the insertion hole 3 such that the first band portion 2 and the second band portion 4 are in close contact with the surface of the tree T. At this time, the elastic protrusions 5 passing through the insertion holes 3 return elastically as shown in an enlarged view indicated by a dashed-dotted circle Ke in FIG. Locking to the edge prevents easy removal. Therefore, the bird and beast harm prevention tool 1 is held in a state of being wound around the tree T as shown in FIG. As described above, since the birds and beasts harm prevention tool 1 according to the present embodiment does not require a separate fixing means, it can be mounted very easily, and the cost can be reduced by reducing the number of parts.
[0020]
In the mounted bird and animal harm prevention tool 1, the distal end 4f of the second band portion 4 having the length Ld protrudes from the insertion hole 3 as shown in FIGS. 1 and 3, and the distal end of the distal end 4f is free. It will be at the end and will be shaken by wind and the like. Therefore, the bird and beast harm prevention device 1 is shaped by the first band portion 2 (second band portion 4) wound around the tree T and the front end side 4f of the second band portion 4 projecting laterally from the tree T. It is complicated, and the tree T can be effectively protected from the bird A. That is, the tree T is protected from the habit that the birds and beasts A do not approach artificial structures added artificially. In particular, if the predetermined position Xe to which the bird and animal harm prevention device 1 is attached is selected to be about 90 cm above the ground, the eye level is higher for a relatively large bird or animal A such as a bear or a deer. The harm prevention effect can be enhanced.
[0021]
On the other hand, when the tree T grows and becomes large in diameter, the bird and beast harm prevention tool 1 wrapped around the tree T also spreads, but the elastic protrusions 5 are indicated by phantom lines in the enlarged view of FIG. Since it elastically deforms like the elastic protruding portion 5s, it goes over the edge of the insertion hole 3 and the diameter of the bird and animal harm prevention tool 1 also increases. The diameter of the bird and beast harm prevention device 1 that can be followed at this time can be arbitrarily set by selecting the length Ld of the second band portion 4. Therefore, breakage of the bird and animal harm prevention tool 1 due to the growth of the tree T can be reliably avoided.
[0022]
In addition, since the bird and beast harm prevention tool 1 is formed by the net member N, air permeability is secured, and the inside of the wrapped first band portion 2 and the second band portion 4 is prevented from being stuffy, and sunlight is prevented. , The favorable natural environment can be maintained. Moreover, if the bird and animal harm prevention device 1 is formed by blending a biodegradable resin with an appropriate amount of a light stabilizer for a polymer, the weather resistance can be remarkably improved even in an outdoor environment, and it can be worn for a long time. Possible, that is, the effect of preventing birds and beasts harm can be maintained for a long period of time, and even if the birds and beasts harm prevention tool 1 is left on the ground as it is when the tree T is cut down by cutting or the like, natural It is decomposed into water and carbon dioxide by microorganisms in the environment and does not adversely affect the natural environment.
[0023]
On the other hand, FIG. 4 shows a bird and animal harm prevention tool (growth cover) 1e according to a modified embodiment of the present invention.
[0024]
The bird and animal harm prevention device 1e according to the modified embodiment uses the first band portion 2 having a relatively large width, specifically, the first band portion 2 having a width about three times that of the embodiment shown in FIG. In this case, three insertion holes 3 are provided at predetermined intervals in the width direction, and three corresponding second band portions 4 are provided. In this way, the width of the first band portion 2 can be increased as necessary, and a plurality of insertion holes 3 and the second band portions 4 can be provided correspondingly. The other basic configuration and shape are the same as those of the embodiment shown in FIG. Therefore, in FIG. 4, the same parts as those in FIG. 2 are denoted by the same reference numerals, and the configuration is clarified.
[0025]
Further, the first band portion 2 and the second band portion 4 have been exemplified by the case where the net member N is used. However, as shown by a two-dot chain line circle Kc in FIG. The portion 2) may be formed of a sheet-like second band portion 4s without mesh (the same applies to the first band portion 2), and the second band portion 4s may be provided with the elastic protrusions 5. In this case, the growth covers 1e and 1 can be used as a heat insulating cover for the tree T or the like.
[0026]
Although the embodiments have been described in detail above, the present invention is not limited to such embodiments, and any configuration, shape, material, quantity, and the like of the details can be set without departing from the scope of the present invention. Can be changed, added, or deleted. For example, the shape of the guide piece 11 may be formed in the shape of a pointed tip (triangle), and the repelling effect on the bird A may be further enhanced. In addition, although the case where one bird and animal harm prevention tool 1 is mounted on the tree T is shown, a plurality of bird and animal harm prevention tools 1 may be mounted at a plurality of different heights in the tree T. Furthermore, although the tree T is illustrated as a growth product, the tree T may be used as an identification number or the like for observing the growth of an animal by winding it around the trunk of the animal.
[0027]
【The invention's effect】
As described above, the growth cover according to the present invention is provided with the insertion hole at one longitudinal end of the first band portion wound around the growth product, and is inserted into the insertion hole at the other longitudinal end of the first band portion. A second band portion having a predetermined length is provided, and a plurality of elastic protrusions are respectively provided at predetermined intervals along the longitudinal direction on both sides in the width direction of the second band portion. Since the length from the tip of the elastic projection on one side to the tip of the elastic projection on the other side in the width direction is selected to be longer than the width of the insertion hole in the width direction, the following remarkable effects are obtained. .
[0028]
(1) The diameter of the bird-and-animal harm prevention tool that can follow the growth of the growth product and can follow the breeding can be arbitrarily set by selecting the length of the second band portion. The breakage of the tool can be reliably avoided.
[0029]
(2) Since a separate fixing means is not required, it can be mounted very easily on a grown product, and the cost can be reduced by reducing the number of parts.
[0030]
(3) According to the preferred embodiment, if the first band portion, the second band portion, and the elastic protrusion are integrally formed by a net member using an elastic material, manufacture can be facilitated and air permeability can be ensured. Thereby, the inside of the wound first band portion and the second band portion can be prevented from being stuffy, and a favorable natural environment can be maintained by passing sunlight.
[0031]
(4) According to a preferred embodiment, when applied to a tree as a growth product and used as a bird and animal harm prevention device, the first band portion (the second band portion) wrapped around the tree and the horizontal direction from the tree. Since the tip end of the second band portion protruding from the front end can complicate the bird and animal harm prevention device in shape, the tree can be more effectively protected from birds and animals.
