DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shape holder for assisting a shape holding of a protective cover placed around a seedling to protect the seedling.

[0002]

2. Description of the Related Art Conventionally, a technique has been known in which, for example, in order to protect a seedling planted in a mountain forest or the like from wildlife or the like, the periphery of the planted seedling is covered with a cylindrical protective cover made of synthetic resin. In such a technique, as shown in FIG.
After the planting of the seedlings N is completed, a tubular protective cover 51 is placed so as to surround the periphery of the seedlings N, and a part of the lower end is buried in the soil as necessary, and the protective cover 51 is used to protect wild animals such as deer, rabbits and rats. They try to protect animals from damage.

[0003] On the other hand, if the protective cover 51 is simply covered in this way, there is a problem in that the protective cover 51 falls down due to a strong wind or an animal falls down. Therefore, as shown in FIG. In some cases, a method is adopted in which the support column 52 is erected, and the protective cover 51 is fixed to the support column 52 with a string M or the like.

[0004]

However, in the case where the protective cover 51 is tied to the column 52 and fixed as described above, the protective cover 51 is made of synthetic resin and its tubular shape is relatively easily collapsed. If it is too long, there is a problem that the tube is crushed or the shape is lost, and there is a problem that the growth of the seedlings is hindered. In addition, if the user tries to tie them carefully so that they do not lose their shape, there is a problem that time is required for fixing work and the working efficiency is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and aims to improve the efficiency of the work such as fixing work by ensuring the shape of the protective cover is ensured so that the seedlings can be grown healthy. Aim.

[0006]

In order to achieve the above-mentioned object, the present invention provides a seedling protection cover shape holder for holding the shape of a cylindrical seedling protection cover, which is substantially the same as the outer shape of the tube of the seedling protection cover. The main body of the holder has a thin-plate cylindrical shape having the inner surface shape described above, and a locking projection protrudes outward from a predetermined portion of the main body of the holder.

Here, since the shape of the seedling protective cover is, for example, a cylinder having a circular cross section or a polygonal cross section, the holder main body is required to hold the shape of the protective cover according to the shape of the protective cover. From a thin plate material such as synthetic resin having high strength, into a cylindrical shape having an inner surface shape substantially matching the outer surface shape of the protective cover, and a locking projection protruding outward from a predetermined portion of the holder main body. It is preferable to form a single piece because the strength increases. In addition, by providing a flange on the holder, the strength of the holder can be further increased.

[0008] When the locking projection is used to fix the protective cover and the supporting column supporting the protective cover with a string or the like, the fixing operation is facilitated. For this reason, it is preferable that the locking projection is provided with a locking portion such as a hook or a through-hole capable of locking a fixing string or the like. The type of the string or the like is arbitrary, and a string of natural fiber, chemical fiber, or the like, a leather product, a metal wire, or the like may be used as long as the string can be fixed.

The number of locking projections is arbitrary, and may be one, two or more. Incidentally, if a plurality of columns are provided, even if the number of columns is increased, the columns can be fixed to the respective columns, and the columns can be made more difficult to fall.

[0010] According to the second aspect, the locking projection comprises an axially flat flat surface portion and a through hole provided in the flat surface portion. By forming such a locking projection, for example, when fixing to a support, it is possible to fix the support with the side surface of the support in contact with the flat surface portion, and it is possible to fix the support more firmly.

[0011]

Embodiments of the present invention will be described with reference to the accompanying drawings. Here, FIGS. 1 and 2 are explanatory views showing an example of a shape holder for a seedling protective cover according to the present invention, and FIG. 3 is an explanatory view of a use state.

[0012] The shape retainer for a seedling protection cover according to the present invention is a cylindrical protection provided for protecting seedlings from damage by wildlife when planting saplings such as cedar, cypress and other hardwoods. The protective cover C has been developed as an auxiliary tool for retaining the shape of the cover C. The protective cover C is formed of a synthetic resin in the form of a cylindrical body having a circular cross section or a polygonal cross section and both ends are open, and surrounds the seedling N planted. It is installed to surround.

At this time, as shown in FIG. 4 (A), the protection cover C can be obtained by simply embedding a part of the lower end portion in the soil.
To fall down by the wind or by animals etc.,
As shown in FIG. 4 (B), it is general that the support posts S and the like are erected and fixed. Therefore, in the related art, the support posts S and the like are erected near the protective cover C and the strings M and the like are attached to the support S. With protective cover C
Tied and fixed.

For this reason, the protective cover C tied with the string M or the like
Is liable to be crushed or lose its shape, which tends to have an adverse effect on the growth of the seedlings N in the cylinder. In the present invention, the use of the shape holder 1 prevents the shape of the protective cover from being deformed. At the same time, the fixing work can be easily performed.

As shown in FIG. 1, an example of the shape retainer 1 is a thin-plate cylindrical retainer body 2 having an inner surface shape substantially the same as the outer surface shape of the protective cover. A locking projection 3 projecting outward from the portion 2;
The locking projection 3 is provided with a through hole h. Then, the cylindrical holder main body 2 can be fitted to the outer surface of the protective cover C.

Incidentally, the holder main body 2 and the locking projections 3 of the shape holder 1 are integrally formed of synthetic resin. At this time, the type of synthetic resin has a certain degree of strength (rigidity). It is arbitrary as long as it has, for example, polypropylene (random polypropylene, block polypropylene, syndiotactic polypropylene), polyethylene (high-density polyethylene, medium-density polyethylene, low-density polyethylene, polyethylene polymerized using a metallocene catalyst), Polyolefin such as an ethylene copolymer, hard or semi-hard polyvinyl chloride, a copolymerized synthetic resin of an olefin monomer and a vinyl chloride monomer, or a mixture thereof can be used.

The protective cover C is also made of a similar synthetic resin. The protective cover C to which the hexagonal cross section holder 1 shown in FIG. 1 is applied has a height of, for example, about 1800 m.
m, inner diameter of hexagonal cylinder (diagonal length of corner) is about 120
mm, so that the holder body 2
Is formed with a cylindrical diameter that can be fitted to it, and has a thickness of about 0.1 to 3.0 mm and an axial length a of 1
Make it about 0.0 to 60 mm. Of course, the cylindrical shape of the protective cover may be a polygon other than a hexagon, a circle, an ellipse, or the like.

In the case of the embodiment, the locking projection 3 is a plate-shaped projection whose flat surface portion f becomes flat along the axial direction of the holder main body. In the embodiment shown in FIG. And a through hole h that penetrates in the lateral direction is formed in each intermediate portion.

Although the form of the locking projection 3 is arbitrary,
If a flat flat surface portion f is formed along the axial direction of the holder main body portion, the side surface of the column can be brought into contact with this flat surface portion f and fixed with a large contact area, and fixed in a more firm state I can do it.

Next, an example of use of the shape holder 1 will be described with reference to FIG. As shown in FIG. 3, when the seedling N is planted, a protective cover C is placed so as to cover the periphery of the seedling N, and a support S is provided near the protective cover C.
Is established. At this time, the shape retainer 1 is fitted on the protective cover C in advance, and the locking projections 3 of the shape retainer 1 are fitted.
Is installed in such a direction as to approach the support S.

Next, the string M or the like for fixing is passed through the through hole h of the projection 3 for locking, and the string M or the like is bound to the column S. At this time, if the string M or the like is tightened and fixed, the side surface of the column S comes into close contact with the flat surface portion f of the locking projection 3 and can be fixed at a fixed position. There is no defect such as deformation. In addition, since this fixing operation is only an operation of tying the through hole h to the column S through the string M or the like, the fixing operation is extremely easy, and the shape of the protective cover C is crushed or deformed by the shape holder 1. Or troubles such as

After that, if necessary, the surrounding area of the lower end of the protective cover C is buried or the like to partially bury the protective cover C so that the invasion of small animals such as rats can be surely prevented.

By the way, in the embodiment described above, the example in which a pair of the locking projections 3 is provided and the case where the number of the pillars S is one has been described. However, two pillars S are provided on both sides and both the pillars S are provided. The locking projections 3 may be fixed to each other, or the locking projections 3 may be provided at only one position for one support S as shown in FIG. Also in this case, if the fixing is performed in the same manner as described above, the shape of the protective cover C can be maintained, and the fixing operation can be performed easily.

The present invention is not limited to the above embodiment. Those having substantially the same configuration as those described in the claims of the present invention and exhibiting the same operation and effect belong to the technical scope of the present invention. For example, the cylindrical shape and size are merely examples, and a synthetic resin material and the like are also arbitrary. In addition, the locking projection 3 may be provided with a locking portion that can hook the string M or the like instead of the through hole h. Further, in the embodiment shown in FIG. 3, the shape holders 1 are fitted to the upper and lower two places of the protective cover C, but of course, the number is arbitrary.

[0025]

As described above, the shape retainer for a seedling protective cover according to the present invention has a thin plate cylindrical retainer body having an inner surface shape substantially the same as the outer surface shape of the protective cover tube, and the retainer. Since it is constituted by the locking projection projecting outward from a predetermined portion of the main body, the work of fixing the protective cover can be easily performed, and the protective cover can be prevented from being deformed. Further, if a flat flat surface in the axial direction of the holder main body is formed as the locking projection as in claim 2,
It can be fixed more firmly in place.
