DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION The disclosed technology belongs to the technical field of a sheet-like blanket structure for protecting a natural grass planted on a ground such as a soccer stadium or a golf driving range with time.

2. Description of the Related Art As is well known, there has been a remarkable improvement in civic life in recent years due to the prosperity of various industries supported by the advanced development of science and technology. Soccer and golf are gaining in popularity due to their popularity. In particular, in the soccer competition, as seen in the J-League, even the taste of civil events has been seen, and the soccer boom has been smaller than the professional league.
The junior high school students and students are overheating. In addition, golf fever is prosperous in middle-aged people,
Golf driving ranges on holidays and at night are on the rise as a company. However, in the case of the seed soccer stadium or the golf driving range, a natural lawn (there is also an artificial lawn in the case of the stadium or the driving range for economic reasons) in the golf course. In general, the soccer stadium and golf driving range have a very large area, and during the holidays when competitions and training are not always held, exhibitions of used car sales, etc. May be used for various events.
Therefore, the natural lawn planted on the ground of the stadium or the practice field may be repeatedly worn out over time under severe conditions that are severely damaged by intense practice or repeated high pressure loads. Is likely to be damaged by the consolidation of the ground soil due to the applied pressing load, and in the case of regular soccer games and golf practice, the natural lawn will be damaged in a damaged state and cannot be used. A state is emerging. In particular, in the case of a soccer stadium, if the length of vegetation deeply affecting the elasticity of the natural grass is excessive due to the habits and conditions of the club team and players used, it may hinder the competition and practice. There is. By the way, soccer stadiums and golf driving ranges are in the narrow terrain of Japan, especially in urban areas where there is not enough area provided, and uniform soccer stadiums and driving ranges are damaged by overuse. It is frequently used in other event venues and the like as described above, and at present, the condition of the original stadium and practice field is not good. In order to cope with this, in order to protect natural grass vegetated on the ground of a soccer stadium or a golf driving range, a protective material covering at least a frequently used area of the natural grass has become necessary. For example, as shown in FIG. 8, each unit having air vent holes formed at regular pitches or randomly at a predetermined pitch or at random in a brush-shaped block 1 having an elastic body made of rubber or the like as shown in FIG. A mode in which the protective material 4 is formed by connecting to each other through a chuck or the like to form a predetermined area and set on the natural lawn 3 as a protective material 4 has been devised and partially put into practical use.

However, in the protection material of the conventional type, each unit block is directly set on the natural lawn 3, so that a pressing load such as a practice is directly applied to the natural lawn. As a result of frequent repetition of application to the lawn 3 and abrasion of the natural lawn 3 and solidification of the ground floor soil, the above-described damage cannot be completely prevented. In particular, as described above, the natural lawn 3 has a vegetation length of which the elasticity at the time of an official competition or an equivalent practice is substantially determined by a club team or a player. However, when a pressure is applied to the natural lawn 3 for a long time, there is a problem that it is difficult to maintain a good condition due to damage caused. In addition, since each unit must be connected and laid on a natural lawn 3 of a stadium or a practice field having a considerably large area through a joint, the setting and resetting are extremely complicated in handling. In addition, there is an inconvenience that when severe training is desired on an artificial grass instead of a natural grass, it is not possible to respond immediately. Further, since the setting and resetting of the protective material 5 is complicated, the protective material 5 is not used for a long time.
Due to the length of time set on the top, it is not possible to cope with heat unevenness and conversely, lack of sunshine etc. under the condition of strong sunshine, and natural grass 3 is damaged in the actual official competition etc. There was a problem that it could not withstand use under the condition. To cope with this, Japanese Patent Application Laid-Open No.
Although there is a sheet mat placed and set on a natural lawn as shown in the invention of 331640, there is a problem that all the problems of the protective material as shown in FIG. 8 cannot be solved.

It is an object of the present invention to prevent damage to a natural lawn planted on the floor soil of a soccer stadium or a golf practice ground based on the above-mentioned prior art due to severe training or events. It is a technical issue to solve the problem of the protective material having a protective function, and it will not be damaged even if it is set on the natural lawn and subjected to long hours of practice, and it can be used for other events when not in use It is easy to handle, requires little time and cost for installation and removal, and can cope with a very large space. It is durable and economically viable. Yes, it is possible to reduce the damage to natural lawn caused by unevenness of sunlight and lack of sunshine, etc. The lawns protective sheet blanket structure is to provide cents.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the construction of the invention of the present application for solving the above-mentioned problems is provided on a surface of a ground of a soccer stadium or a golf driving range.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; Note that the same parts as those in FIG. 8 are described using the same reference numerals. The illustrated embodiment is a mode applied to a soccer stadium provided in an urban area or the like, and can be used for an event venue such as a golf practice or used car sale in cases other than a soccer game or practice. Reference numeral 5 'designates a sheet-like blanket for protecting natural lawn, which is the center of the gist of the invention of the present application, and the roots in the field state on the floor soil 7 such as sawdust, zeolite, sand layer, etc. 8 and is laid and set on a natural lawn 3 vegetated to a predetermined length through a predetermined length. The nonwoven fabric 10 made of nylon or the like of the sheet-like blanket 5 ′ has a predetermined pitch or randomly. The nonwoven fabric 10 made of nylon or the like having small air vent holes 9, 9 having a diameter of about 1 mm has little foldability and has a predetermined strength and rigidity. A spider web made of a thin plastic wire having a diameter of 0.5 mm or the like or a brush-shaped elastic body 11 is integrally attached to the surface by heat fusion or the like. But width 1,2m, length 20-30m
7 is mass-produced in the form of a strip-shaped sheet, and as shown in FIG. 7, is wound up in a roll form, is fed out onto the natural lawn 3 of the soccer field, and is automatically laid and set. The natural lawn 3 and the elastic body 11 are inserted into each other so as to cooperate with each other in elasticity, and the nonwoven fabric 10
Disperses the frequent load applied from above, prevents the natural grass from being worn and the ground soil from consolidating, and eliminates uneven heat and lack of sunlight by venting holes 9, 9 Also, the evaporation of water is good, so that the vegetation of the natural lawn 3 is not damaged at all. Then, both edges of the strip-shaped blanket 5 ′ can be maintained in a mutually connected state by a velcro or a fastener 12 integrally attached to the blanket 5 ′ in advance, and the entire blanket 5 can be maintained. It can be set in a cover shape. In addition, as shown in FIG. 4E, the player playing the nail 13 as the anchor pin or the inverted U-shaped anchor pin 13 'is not injured at the entire edge portion of the blanket 5'. As described above, they are driven in a row through the bag-like cover band 14 to prevent the storm or the low pressure from peeling or blowing off. Therefore, the player is guaranteed to play safely. The bag-shaped cover band 14 is made of the same material as the nonwoven fabric 10, and is integrated by heat fusion or heat fusion. In the above configuration, the sheet-like blanket 5 'of each unit is placed between the elastic body 11 on the upper surface of the natural lawn 3 vegetated through sawdust, zeolite, and a sand layer laid on the upper surface of the ground 6 of a soccer stadium or a golf driving range. When laid and set, the elastic body 11 gradually enters the tip of the natural lawn 3 and intersects and is inserted, and the uppermost sheet-shaped nonwoven fabric 10 is connected to each other with a magic tape, Alternatively, the entire area of the stadium or practice area is covered with a blanket protective material 5 'by adhesively connecting the fasteners 12 and 12. Thus, even if a soccer practice or the like is severely performed on the upper surface of the blanket protective material 5 ′, or if a downward load is applied by a player rushing at a high speed, the load is in a filamentous shape. The load is not transmitted to each of the natural lawns 3 because the load is transmitted to the natural lawn 3 after being dispersed by the nest-like or brush-like elastic body 11, and therefore, the scraping and the ground 6 are not performed. Of the natural lawn 3 is not damaged even if a frequently repeated pressing load is applied, and during this time, even if there is precipitation, the air vent holes 9, 9, 9
, And the air vent holes 9, 9, 9 ...
The natural turf 3 does not hinder the vegetation by naturally permeating through the air vent holes 9 and keeping the vegetation of the natural lawn 3 naturally. or,
Since the blanket 5 'of each unit is connected to each other by a velcro or a fastener 12,
There is no mutual shift or the like. Therefore, damage due to mutual displacement does not occur. Even if an event such as an exhibition of used car sales is performed and a vertical load is similarly applied to the blanket protective material 5 ′ at an appropriate timing during a soccer practice or the like during that time, the elastic body 11 The vertical load is dispersed by the intersection of the natural grass 3 and the natural grass 3, so that the natural grass 3 is not damaged at all. Then, when performing predetermined maintenance such as fertilizing the natural lawn 3 at an appropriate timing, the anchor pin 13 or 13 ′ is pulled out and a magic tape or fastener 12,
By removing 12, the protective member 5 'is collectively wound up in a roll manner, stored as appropriate, and prepared for installation of reset. During this time, when the player practices a predetermined play on the upper surface of the protective material 5 'of the blanket, the anchor pins 13, 13' are covered by the bag-like band-shaped cover 14, so that the anchor pins 13, 13 'are covered. 1
There is no risk of injuries and the like due to 3 ', and the practice can be performed safely. In the embodiment shown in FIG. 5, the knurls (pear-skin-like, rough-like) 1
Are integrally formed in advance at a portion separated from the air vent hole 9 so as to ensure friction on the upper surface of the non-woven fabric 10 when the player exercises or moves the treadle at the time of the event. In this embodiment, as shown in FIG. 6, when laying a mat 17 integrally formed with an artificial turf 16 on the upper surface of the nonwoven fabric 10, as shown in FIG. In this case, it also has a function of preventing peeling in the case where it is performed. And
As shown in FIG. 6, since the artificial grass 16 is integrally formed on the surface of the nonwoven fabric 10 of the blanket 5 ', the feel of the player at the time of practice is similar to that of the natural grass. Is obtained, and the effect of the practice is also improved. When the nonwoven fabric 10 on which the artificial grass 16 is not integrally formed is exposed on the surface of the protective material 5 ', the nonwoven fabric is colored with green or the like, or a suitable vegetation pattern is painted. Is also possible. For the artificial turf 16, a protective material 5 ′ is laid on the surface of the non-woven fabric 10 on the upper surface of the natural turf 3 and then adhered to the non-woven fabric 10 with a magic tape or the like, or formed integrally with the non-woven fabric 10 in advance. It can also be used as a protective material. In any of the embodiments, as shown in FIG.
'Can be wound into a roll and attached to the entire surface, or it can be retracted and removed. However, even in a soccer stadium with a considerably large area, as described above, the nonwoven fabric of each unit is used. 10 Since it is possible to lay in an integrated area at the edges of each other via a velcro or a fastener, the weight of a roll of one unit is not so heavy. It does not take much effort to attach it. It should be noted that the embodiments of the invention of this application are not limited to the above-described embodiments. For example, a spider web of an elastic body, or a spider web in a brush-like filament type male pair, or In addition to the brush shape, various modes can be adopted, such as a mode in which thin filaments of a plastic thin wire having a small diameter are densely implanted and fixed on the lower surface of the nonwoven fabric.
Further, the target place can be applied to a mode in which a natural lawn on a site such as a park or a site of a public facility is planted in addition to a soccer stadium or a golf driving range. Further, the nonwoven fabric sheet is not limited to being made of nylon, but may be made of a material having desired strength and rigidity and having no foldability.

As described above, according to the invention of this application, a natural lawn vegetated on the ground of a soccer training stadium or a golf driving range is basically worn or sloping by holding regular or irregular training or events. In order to maintain the condition of the natural lawn in a bad state at the time of an official competition or an official practice through soil consolidation, etc., cover a predetermined area with a protective material covering the upper surface of the natural lawn. A nylon filament web or brush-like elastic body is integrally laid on the lower surface of the nonwoven fabric, so that the elastic body and the natural lawn intersect and intersect with each other. It is possible to disperse the harsh weight application of the player who practices in the field, so that the natural lawn can be prevented from scuffing and solidifying the ground, and damage to the natural lawn can be prevented. Almost without cause, the function of the natural grass can be exhibited an excellent effect that can be kept in the best condition upon the desired official competitions and official practice. In addition, the nonwoven fabric itself is breathable, and in addition to that, small-diameter air vents are perforated at a predetermined pitch or at random, so that drainage is good, and there is no heat stuffing phenomenon, and the sunshine is appropriately. An excellent effect is achieved in that the vegetation state of the natural lawn can be kept close to nature and good conditions can be maintained. The air vent hole keeps drainage through transpiration, avoids the state of turbulence through the heat of sunlight, keeps the sunshine, and has the excellent effect of obtaining a natural lawn in a natural vegetation state. Is played. In addition, since each unit of the protective material of each blanket can be interconnected via a velcro or a fastener, it can cover the entire area of the soccer stadium or the driving range regardless of the size of the area. Therefore, an excellent effect that the natural lawn in the area can maintain the condition of the best vegetation state is exhibited. Further, since the anchor pin is driven into the ground at a predetermined portion such as the edge of the sheet and functions as an anchor, there is no possibility that the blanket of the protective material is peeled off by the wind or the like and blown off. Further, since the anchor pin is driven into the anchor pin via the safety cover, there is an effect that even when the player practices, the occurrence of scratches or the like of the player due to the anchor pin can be avoided. Further, in the protective sheet-like blanket of the invention of the present application, basically, a spider web or a brush-like elastic body such as a thin plastic wire or the like is integrally formed with the nonwoven fabric. It has sufficient strength and stiffness by making it a basic structure, and has non-folding properties. It can be rolled out and rolled out for easy mass production. If it is easy to set, etc., it saves time and effort, it is cheap in cost, and it is durable, and it can protect the natural grass underneath enough and keep the natural vegetation in the best condition In addition, the excellent effect that the durability of the blanket itself is good is exhibited. In addition, by laying an artificial grass mat on the upper surface of the nonwoven fabric of the blanket, there is an advantage that it is possible to practice in a condition close to the natural state without causing damage to the lower natural grass, and to be able to perform an event or the like. . Then, in a state where the blanket is exposed, the nonwoven fabric is colored in a color state such as green, and is colored,
Also, by painting an appropriate vegetation pattern in a pattern or the like, there is also an effect that a feeling close to a natural state can be obtained even when practicing directly on the upper surface of the nonwoven fabric. In addition, by forming knurls (pear-skin and rough) on the surface of the non-woven fabric, a frictional force is appropriately given to the non-woven fabric even when practicing directly on the upper surface of the non-woven fabric or performing an event. There is also a merit that deviation is prevented and durability is improved.
