DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in means for installing partition lines in a tennis court, such as an un-to-car court or a clay court, in which rainwater easily penetrates and drains well.

[0002]

2. Description of the Related Art Conventionally, as a partitioning wire for a sports facility of this kind, there has been one disclosed in, for example, Japanese Patent Application Laid-Open No. 56-151077. This prior art has an upper edge serving as a partition line, and the upper edge is made up of a plurality of identical wires whose end faces abut each other, and each wire has at least two wires on its lower surface. A spacer wire which is mounted on a base and which is detachably connected to the base and which is used inside a runway of a sports facility, wherein the spacer 3 is formed of an elastic material; A rectangular support 5 having an open U-shaped cross section is embedded in the lower surface of the support, and the support is surrounded by spacers 3 on at least both sides thereof, and has a hollow portion 5a. A sports clip characterized in that a spring clip 7 having a substantially U-shaped cross section is fixed, and the foot portion of the spring clip elastically sandwiches the head 8a of a fixing screw 8 disposed in the base, for example. Running the facility A partition line material to be used on the inside.

[0003]

The above-mentioned prior art is such that a runway partitioning wire is installed inside the runway and higher than the runway surface, and from the viewpoint of preventing danger to runners, a flexible elastic material such as urethane rubber is used. The upper edge body is fixed to the spacer made in the above, and the spacer itself is elastically fixed to the running surface by a fixing screw via a spring clip by a support. Therefore, this conventional example is complicated and difficult to construct, and firstly, since it is a partition wire protruding from the competition surface, it is essentially and seriously used as a tennis court division line. There is a problem.

[0004] In addition, as disclosed in JP-A-55-96188 and JP-A-55-96189,
It is also known that the ground surface of an all-weather athletics stadium is hard-paved with a pavement material mixed with a magnetic material, and a mark for marking having a magnet is magnetically attracted and installed on the magnetic pavement surface.
However, in this conventional example, the construction surface has to be hardly paved, so the construction cost is high,
Since there is no infiltration of rainwater, drainage is poor and there is a serious problem that it cannot be used as a line installation means for tennis courts such as an outdoor car court or a clay court at all.

On the other hand, at present, as a means of setting a division line of a tennis court with good drainage, in a clay court managed by Niiza municipal in Saitama Prefecture or an uncar park in an Omiya municipal sports ground, a means for fixing a line tape to the court surface is used.
"Square nails" are stuck in two rows in a zigzag pattern at ~ 7cm intervals and fixed. The double official warfare clay court is about 24m and 11m in length and width respectively, and the total length is about 145m
Since about 3,000 nails are manually driven into the coat surface from above the line tape, a large amount of metal resources such as iron are required, nailing work is difficult, and the line tape is weakened due to nail holes, and nails are weakened. There are many problems that there are many misjudgments and injuries due to slipping out.

According to the present invention, in order to eliminate the above-mentioned problems, a band frame laid flat and buried on a court surface with its top surface exposed is used as a partition line installation material in a tennis court in which rainwater easily penetrates and has good drainage. The purpose is to easily and inexpensively construct a non-hazardous dividing line by installing a line tape on the upper surface in a detachable manner by means of concave-convex elastic engagement and laying the line tape almost flush with the coated surface. And

[0007]

SUMMARY OF THE INVENTION An object of the present invention described above is to provide a tennis court with rainwater that easily penetrates and has a good drainage. While being buried and fixed in a state where the upper surface is exposed by a projecting underground projecting piece, inwardly projecting ridges are provided in parallel on both side edges of the band frame on both sides of the long groove cut out on the upper surface of the band frame, A band-shaped line tape is laid flat on the long groove between the ridges, and the ridge connected to the lower part of the tape is engaged with the lower part of the ridge to cover the rim. This was achieved by fixing the line tape almost flush with the coated surface.

[0008]
