Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to the protection of sandboxes installed in parks and the like, and more specifically, it can prevent the entry of small animals such as dogs and cats without being closed or isolated, and can prevent contamination of sand by manure, It is also intended to promote the recycling of PET bottles.
[0002]
[Prior art]
In recent years, a large amount of Escherichia coli and parasite eggs have been detected in the sand of sandboxes, which may be the result of sand contamination caused by the excrement of small animals such as dogs and cats. It has been reported.
This situation is particularly noticeable in urban areas where most of the ground surface is covered with pavement and the area of soil and sand is decreasing, and in addition to stray dogs and stray cats, keep pets free. Moreover, when taking a walk, there are many heartless owners who use sandboxes as pet toilets, which causes further contamination.
And children playing in such a polluted sandbox can naturally touch their mouths and eyes with their hands and fingers when messing around, and are at risk of coliforms and parasites. It is. Escherichia coli causes diarrhea and abdominal pain, and dog and cat roundworm eggs enter the mouth to become larvae, which break through the digestive tract and move to various parts of the body. Moving to the liver or other internal organs may disrupt liver function, and moving to the eyes may cause vision loss and eventually blindness.
[0003]
Conventionally, as countermeasures for the above problems, for example, a fence that is high enough to prevent small animals such as dogs and cats from jumping around the sandbox, and repellents that these small animals dislike are mixed into the sand. As anti-contamination measures, it is known to use antibacterial sand that has the effect of sterilizing and extinguishing E. coli and parasite eggs released from manure. However, when a plate-like or wall-like fence is used, the visibility between the inside and outside of the house deteriorates and the sandbox becomes closed, and the lattice-like or net-like fence becomes like a kite. There was also criticism that the children playing inside would be in a state of isolation, and the customer fell. In addition, the efficacy of repellents and antibacterial sands declines over time, and replenishment and replacement are expensive.
[0004]
Therefore, the applicant of the present application previously proposed a “protective fence for sandboxes” in which a protective fence composed of transparent or semi-transparent plastic bottles was placed around the sandbox (Japanese Patent Application No. 6-305340). .
The plastic bottles that make up this protective fence are transparent or semi-transparent and have a substantially cylindrical shape, so they slightly reflect light, especially when water is placed inside. Because it emits strange reflected light, small animals such as dogs and cats tend not to get close to it.
For this reason, this protective fence can be used to see the inside of the sandbox easily from the outside because it can be expected to have a sufficient effect at a height as low as one or two layers when PET bottles are used vertically. At the same time, the outside can be seen from the inside, preventing the entrance of small animals such as dogs and cats without the sandbox becoming closed or children being isolated and contained. It is something that can be done.
[0005]
[Problems to be solved by the invention]
The present invention further improves the protection fence for such a sandbox, and can prevent the entry of small animals such as dogs and cats without being closed or isolated, and can prevent the contamination of sand by manure. It is intended to provide a protective fence for sandboxes, and at the same time, it aims to further promote the recycling of PET bottles.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the protective fence for sandboxes according to the present invention is a combination of transparent or semi-transparent plastic bottles that are installed around sandboxes to prevent the entry of small animals such as dogs and cats. Further, the protection fence is provided with a windmill member, a teg member, and the like.
In addition to forming the windmill member itself with plastic bottles, the protective fence is constructed by drawing various patterns and designs by arranging transparent or translucent plastic bottles in appropriate combinations. is there.
[0007]
In the above and the following description, the term “pet bottle” strictly refers to bottle-shaped containers made of PET (polyethylene terephthalanol) resin, but the present invention is not limited to this material and shape. For example, containers of other materials and materials that are visually similar, such as containers of glass and various plastics, are generally used as generic terms, and their shapes are not necessarily specified as general bottle types. is not.
The “windmill member” is used as a term that generally means a member that rotates by wind power, and the “Tegs member” generally means a thin string-like member such as a fishing line or a packing string. It is used as a term.
[0008]
The protection fence for sandboxes of the present invention having such a structure is configured by a transparent or translucent plastic bottle that is not likely to be disliked by small animals such as dogs and cats. Can be prevented.
In addition, since a sufficient effect can be expected even at a relatively low height, the visibility of the inside and outside is increased, and the sandbox is not closed, and the children are not isolated or housed. In addition, it is possible to prevent the entry of small animals such as dogs and cats while maintaining an open feeling.
Further, by providing a windmill member and a teg member in such a protective fence, the windmill member rotation and the sound caused by the rotation or the strange feel of the teg member are more fearful and unfamiliar with small animals such as dogs and cats. Since a pleasant feeling can be given, the approach can be prevented more powerfully.
If the windmill member itself is also formed of plastic bottles, recycling of used plastic bottles can be further promoted, and when a protective fence is formed of plastic bottles, When transparent plastic bottles are appropriately combined and arranged to draw various patterns, a more open feeling can be obtained.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a protective fence 1 for a sandbox according to the present invention, in which a protective fence 1 constituted by combining a plurality of transparent or translucent plastic bottles 3 is installed so as to surround the sandbox 2 and Further, the protective fence 1 is provided with a windmill member 4 and a teg member 5. As shown in FIG. 2, the guard fence 1 uses a bottle-shaped plastic bottle 3 in a vertical state, and a reinforcing bar 8 is inserted over a structural steel 7 attached to a foundation concrete 6 surrounding the sandbox 2. This is a combination of a large number of stacks in three stages. In addition, if a revolving door is employed at the entrance as shown in FIG. 1, entry of small animals such as dogs and cats can be prevented, which is preferable.
The upper part 9 of each reinforcing bar 8 is fixed by penetrating a flat bar 10 that holds the plastic bottle 3, and a tees member 5 is installed at the tip 11 thereof.
Moreover, the shaft 12 which supports the windmill member 4 is attached to several of the front-end | tip parts 11 via the attachment metal fitting 13 so that rotation is possible.
The reinforcing bars 8 can be replaced with a string or the like every few, and this is preferable because the cost can be reduced.
[0010]
FIG. 3 shows the details of the windmill member 4, which is configured by forming a blade portion 4 a by incising the side surface of the plastic bottle 3 to cause the shaft 12 to penetrate the bottom portion 3 a and the mouth portion 3 b. is there.
The windmill member 4 is rotated by wind power, but the rotation and further the sound of the rotation give a very strong fear and discomfort to small animals such as dogs and cats.
In addition, as the windmill member, any other wind turbine member can be used as long as it is rotated by wind power. However, by using the plastic bottle 3 in this way, the recycling utilization of the used plastic bottle is further promoted. Can be preferable.
[0011]
Although the tegu member 5 is a thin string-like object, it is difficult to see from a distance. It gives a feeling of pleasure or disgust.
Moreover, since the upper part of the protective fence 1 has a shape in which the upper part 9 of the reinforcing bar 8 and the tip part 11 on which the teg members 5 are erected are projected on the surface of the flat steel 10, particularly a cat or the like jumps on or walks. It is impossible to do.
This is reasonable even from the habits of a cat that does not fly off the fence unless you confirm the other side to jump down and land, and once it is impossible to get on the top It will not jump over.
[0012]
Furthermore, when the protective fence 1 is configured with the plastic bottles 3 as described above, when various patterns are drawn by appropriately combining the transparent or translucent plastic bottles 3, a more open feeling is provided. The aesthetic appearance is further preferable.
[0013]
【The invention's effect】
The protective fence for sandboxes according to the present invention is as described above, and prevents sandboxes from entering dogs and cats without causing the sandbox to be closed or isolated, and contamination of sand by manure Can be prevented.
In other words, because the protective fence is made up of transparent or translucent plastic bottles that tend to be afraid of small animals such as dogs and cats because they emit subtle, strange and strange reflected light, these small animals enter the sandbox Can be prevented.
As a result, a sufficient effect can be expected even if the protective fence is set to a relatively low height, so the visibility of the sandbox inside and outside is improved, and the sandbox appears to be closed or children are isolated and contained. It is possible to prevent the entry of small animals while maintaining an open sensation without becoming uncomfortable.
Further, since the windmill member and the teg member are further provided, the sound caused by the rotation and rotation of the windmill member or the strange feeling of the teg member gives a stronger fear and discomfort to small animals such as dogs and cats. Therefore, the approach can be prevented more strongly.
In addition, when the windmill member itself is also made of plastic bottles, it is possible to further promote the recycling of used plastic bottles. When transparent PET bottles are appropriately combined and arranged to draw various patterns and the like, a more open sensation can be obtained, and the aesthetics are further preferable.
