Description

[Detailed explanation of the invention] Conventionally, fences around sports stadiums have been made of rigid bodies such as concrete, wooden boards, or iron plates, or wire mesh stretched over steel frames.
Accidents were often seen where competitors collided with these fences and were injured.

The inventor of the present invention previously proposed a method to prevent injuries caused by players colliding with the fence by gluing foam to the entire surface of the fence in such stadiums and providing a weather-resistant and water-resistant coating on the surface. devised a new fence that made it possible to
Publication No.). On the other hand, the cushion material or mat is then bonded via a face-to-face bonding member (so-called magic tape) consisting of a member having a large number of synthetic fiber monofilament hook layers on the surface and a member having a large number of synthetic fiber loop layers on the surface. A danger prevention fence for stadiums that is fixed to the fence has also been proposed (publication number 13175 of 1983).

However, according to these ideas, this method cannot be applied to the wire meshes found in the so-called ratkey zones on the left and right sides of baseball stadiums these days, and therefore, accidents caused by collisions with such wire meshes, especially their steel frames, cannot be applied. could not be prevented. Also, in these ideas,
Since the foam or the member having the loop layer is glued to the fence with adhesive, it takes a long time to construct it on site, and once it is glued, it has to be peeled off and moved to another part of the fence. There were inconveniences such as not being able to do anything.

Furthermore, a foam is filled between the rubber surface plate and the back plate, and a metal fitting is fitted and fixed into the recessed part provided in the back plate, and is separately fixed to the fence of the stadium in advance. A shock accident prevention board for athletic events has also been proposed, in which the back plate is fixed to the wall surface by connecting the above-mentioned receiving bracket to a mounting plate placed on the wall.
-35175). However, the method of adhering the back plate to the fence in this invention was too simple, and the overall durability and stability were lacking. Therefore, in order to further eliminate the above-mentioned inconvenience, the inventor of the present invention shortened the on-site construction period by configuring the three members of the semi-rigid board, the foam material, and the covering into an integrated unit in advance, and also made it possible to use wire mesh fencing instead. We proposed a fence for baseball stadiums that can be easily attached to the fence, does not require the use of adhesives, and has sufficient durability and stability.

The present invention further simplifies and shortens the construction method and period by sewing so-called magic tape onto a unit that is almost the same as the unit for the baseball field fence described above.

To explain one example of the present invention with reference to the drawings, the first
The figure is a front view of the unit according to the present invention with part of the coating removed, FIG. 2 is a side view of the same, FIG. 3 is a plan view of the same, and FIG. 4 is a perspective view of the unit when it is connected. In the figure, 1 is a unit, and 2 is a shock-absorbing foam in this unit 1. This foam may be made of, for example, semi-hard or soft ether-based or ester-based urethane foam, rubber sponge, or soft vinyl sponge. It will be done. 3 is a weather-resistant and water-resistant coating that covers and adheres to the surface of the foam to improve the bounce of the ball, and is made of, for example, natural or synthetic rubber,
Made of leather, cloth or glass fiber. The unit formed integrally in this way is
As shown in the front view of the figure, a lug 4 is formed on one edge so as to slightly protrude, and a tape 5a having a loop layer is sewn to the back side of the lug 4. 5b is a tape having a hook layer sewn on the other edge, which corresponds to the aforementioned tape 5a. 6a and 6b are flaps extending vertically from the back of the unit 1;
These flaps 6a and 6b have eyelets 7 for attachment,
7,... are provided. Reference numeral 8 designates an air vent hole drilled in the side of the unit 1. In addition, 9 is a concrete fence, 10 is an anchor bolt,
11 is the ground.

The unit 1 of the present invention as described above has a foam 2
is covered with coating 3 and mass-produced in advance at a factory.
Then, this unit 1 is fixed to the fence 9 with anchor bolts 10 through the eyelet 7 at the site, and the tapes 5a and 5b of the left and right units 1, 1 are fixed.
All you have to do is keep it in close contact with. Therefore, with the unit of the invention, construction operations and time are significantly simplified and shortened. In addition, even after such a unit 1 is installed on the fence 9, it cannot be attached to the anchor bolt 1.
0, 10, . . . can be easily removed, and therefore the unit 1 can be moved to another fence part.

Furthermore, as described above, the present invention allows the ears 4 of the unit 1 to protrude slightly from the edges, and the magic tape 5
a, 5b, when such units 1 are successively attached to the fence 9, there is almost no seam between one unit and the next unit.

The width of the unit 1 in the present invention is approximately 1 to 2 meters, and the height is determined depending on the height of each fence. Generally, the thickness of the bubble 2 is sufficient as long as it can cushion the impact when a human body collides with this fence, and the thickness of the coating 3 is approximately 1 to 1.
It is about 3mm.

5 and 6 are cross-sectional views showing a construction method using another embodiment of the present invention. In this embodiment, a flap 6a or 6b is provided on the front surface of the unit 1, and its length is approximately twice the thickness of the unit 1. To attach it to the fence 9, first fix the upper flap 6a with the anchor bolt 10 through the hole in the eyelet 7, turn it over as shown by the arrow in Figure 5, and then fix it in the same manner as above. . Also, in FIG. 6, the lower flap 6b is first fixed to the ground 11 and then similarly reversed as indicated by the arrow.

Furthermore, in the present invention, a fastener is attached to the base of the ear 4 of the unit 1 and the corresponding portion of the tape 5b, thereby further strengthening the connection between each unit, and it is also possible to cover this with the ear 4. . Examples of fasteners include soft fasteners made of nylon and fasteners made of iron.

Next, when the present invention is applied to a wire mesh fence, instead of using the anchor bolts 10 to fix it, for example, hooks may be used to hang it on the horizontal beams of the steel frame of the fence. It is also possible to tie it to the steel horizontal crosspiece of the fence using wire, chains, ropes, etc.

According to the unit of the present invention, the installation method is very simple and anyone can perform the installation work without requiring any skill, and the installation time can be greatly shortened. In addition, standardized units are mass-produced in factories, which reduces the construction time and provides an inexpensive cushioning protector. Furthermore, according to the unit of the present invention, repairs can be made by replacing only the damaged unit. In addition, when this unit is used as a fence for a baseball field, it can be constructed without any gaps with the ground, so it has the effect of preventing balls from getting into it.

The unit according to the invention can be used not only for fences in sports stadiums, but also for places where safety is required, such as pedestrian crossings. Furthermore, it can be applied to safety measures not only outdoors but also at home.
