BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detachable inner curb device installed at a boundary between a field and a track in an athletic stadium.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 8, an athletics stadium 10 is provided with an inner rim 13 at a boundary between a field 11 and a track 12. When the athletics stadium 10 is dedicated to athletics, an inner rim curb 13 made of a concrete block is placed at the upper end with a width of 50 mm and a height of 50 mm.
It is a permanent facility buried so as to protrude from the runway surface 19 by about mm. On the other hand, when the athletics stadium 10 is used for multiple purposes, for example, when it is used for a sports event, soccer, rugby, etc. in addition to athletics, the inner rim 13 can be removed.

FIG. 9 shows a detachable conventional example. FIG.
3A, a width of 50 to 60 mm and a depth of 100 to 150 m are provided at a boundary between the field 11 and the track 12.
A curb storage box 14 which also serves as a side groove of about m is installed. A vertical shaft insertion hole 1 is provided in the inner wall portion of the curb storage box 14.
The bearings 15 with the holes 8 are fixed at predetermined intervals. The inner curb 13 is made of a highly durable stainless steel tube having a width of about 50 mm and a height of about 30 mm.
7, a vertically stepped vertical shaft 16 is attached. The inner curb 13 is set at, for example, 1990 mm when installed on a straight line portion of the truck 12, and is set at 990 mm, 1990 mm, and the like when installed at a curved portion.

When used as a track and field stadium, FIG.
As shown in (a), the vertical shaft 16 is inserted into the shaft insertion hole 18 of the bearing 15 and the inner curb 13 is moved 50 m from the running surface 19.
Let m rise. Even in athletics, when the inner kerb 13 is not used partially, or when the inner kerb 13 is not used entirely like rugby, the inner kerb 13 is lifted to be vertical. The shaft 16 is removed from the shaft insertion hole 18 of the bearing 15, and as shown in FIG. 9B, the inner sphere curb 13 is slightly shifted left and right and inserted into the curb storage box 14. Since the depth from the runway surface 19 to the upper surface of the bearing 15 is made equal to the height of the inner curb 13,
The upper surface of the inner rim 13 is flattened with the running surface 19 and stored.

In FIG. 9C, only the bearings 15 are provided at predetermined intervals in place of the curb storage boxes 14 so as to be flush with the road surface 19. In this case, when not in use, the unused inner rim 13 is removed, placed on a trolley, transported to the hangar, and temporarily stored.

[0006]

Among the conventional examples described above, the inner sphere curb 13 is stored in the curb storage box 14 because:
There is an advantage that there is no need to pull out the inner rim 13 and place it on a trolley and transport it to the hangar when not in use. However, the inner rim 13 is made of metal such as stainless steel or aluminum, which does not rust and has excellent appearance. Therefore, there is a problem in that when it is wet with water, it is extremely slippery, and when it is put on a spike shoe, it may slip or sprain its ankle.

It is safe to remove the inner curb 13 and temporarily store it when not in use, since the area of the bearing 15 is extremely small, so that it does not slip or sprain the ankle, it is safe. Since the work of transporting and storing the inner sphere curb 13 to the hangar by a trolley is troublesome, and the vertical shaft 16 of the inner sphere curb 13 is accurately adjusted in advance in accordance with the shaft insertion hole 18 of the bearing 15, When re-installing, there is a problem that the operation of attaching the original position to the original place is troublesome, and furthermore, the shaft insertion hole 18 of the bearing 15 is clogged and the vertical shaft 16 becomes difficult to be inserted. .

An object of the present invention is to provide a device in which the inner curb 13 can be easily attached and detached and stored without slipping.
