DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a front view showing a portion around a soccer goal of a fence according to the present invention. As shown, 1
Is a fence, 2 is a soccer goal, and fence 1 is erected immediately outside the goal line (not shown) and is used here for bound mini soccer. The fence 1 particularly has a plurality of goal side net fences 3 divided along the goal line direction. The height H _{1 of the} goal side net fence 3 is set to 4 m, and the height H 2 is 2 m.
The lower fence 4 and the upper fence 5 have a two-stage structure with the position of as a boundary.

The lower fence 4 is mainly composed of a lower frame body 6 formed of an angle member in a rectangular shape, and a lower net 7 stretched over the lower frame body 6. The width W ₁ of the lower frame 6 is
The length is 2.12 m, and the angle material is L-shaped and has a size of 40 × 40 × 3 mm. The lower net 7 uses an aluminum steel covered wire known as a wire for electric wires for its wire material. The aluminum steel wire has a diameter of 2 mm, is colored and is assembled in a rhombus with a 25 mm pitch. Thus, the lower net 7 is applied with a predetermined tension from four directions to form a repulsive surface for bouncing the ball.

The upper fence 5 is mainly composed of an upper frame body 8 formed in a U-shape that opens downward and an upper net 9 stretched over the upper frame body 8. The upper frame body 8 is formed of a circular pipe material (φ34.0 × 2.3 mm) that is lighter than the angle material, is welded and fixed to the lower frame body 6, and has a width slightly smaller than that of the lower frame body 6. . The upper frame 8 has a reinforcing frame 10 fixed to the inside thereof. The reinforcing frame 10 has a diameter
Formed from 10 mm round steel and functioning as a beam,
From the rectangular portion 11 along the upper frame body 8, the diagonal portion 12 that diagonally bridges the rectangular portion 11, and the plurality of protruding portions 13 that project from the lower side portion of the rectangular portion 11 and are coupled to the lower frame body 6. It is formed. Then, a predetermined tension is applied from four directions to the surface side of the reinforcing frame 10, that is, the field side, and the upper net 9 is applied.
Is installed. Similarly to the above, the upper net 9 is also formed by combining colored steel wire, which is a wire rod having a diameter of 2 mm, in a rhombus shape. In particular, the pitch of the upper net 9 is 50 mm, which is larger than that of the lower net 7.

As shown in FIG. 2, on the back side of the goal-side net fence 3, there are provided leg portions 14 for vertically arranging them. The leg portions 14 are vertical portions 1 on both sides of the lower frame body 6.
5, in particular a leg member 16 rotatably connected to its lower end
Having. A stay 17 is rotatably provided on the upper end of the vertical portion 15. The leg member 16 and the stay 17 are L-shaped 40 × 40 × 3 mm angle members.
Connection bracket 18 provided on the tip side of the leg member 16
Then, holes are formed in the tip of the stay 17, and the leg members 16 are horizontally fixed by inserting the fixing bolts 19 into these holes. A weight 20 for preventing a fall is placed on the tip of the leg member 16.

Thus, the goal side net fence 3
Can be placed on the ground or floor of a mini soccer field, and can be lifted and moved in this state. The weight 20 prevents the fall due to strong wind or the like. On the other hand, when the fixing bolt 19 is removed, the leg member 16
The stay 17 and the stay 17 can be rotated, and when they are rotated upward, they are folded along the back surface of the net fence 3 as shown by an imaginary line. For example, when it is not used as a mini soccer field on a school ground or the like, by folding the legs 14 and moving them to another place, compact storage in a relatively small space becomes possible.

A cushioning member 21 for cushioning is removably provided on the goal side net fence 3, particularly on the lower side of the lower fence 4 so as to prevent an injury when a player in a competition collides. As shown in FIG. 3, the cushion member 21 is formed in a rectangular plate shape having a height H ₂ of 1 m, a width W ₂ of the same width as the lower fence 4, and a thickness t of 50 mm. The cushion member 21 has a ladder-shaped frame 21a inside,
The claw 22 is projected from the frame 21a so that the lower net 7 can be attached / detached with one touch. When it is removed, it is removed, transported alone and stored in another place. As the material of the buffer plate 23 supported by the frame 21a, foam such as urethane and rubber is adopted. Since the cushion member 21 has the same width as the lower fence 4, the lower frame body 6 is not exposed and a collision with this is prevented.

In use, the goal side net fences 3 are arranged side by side along the goal line. Then, the adjacent leg members 16 are connected by the connecting member 24 (FIG. 2),
All the goal side net fences 3 are integrally connected by connecting the vertical portions 15 of the lower frame bodies 6 adjacent to each other with a connecting ring (not shown). The connecting member 24 and the connecting ring can be removed during disassembly and storage.

Further, as shown in FIG. 1, a goal upper net fence 25 is provided above the soccer goal 2. Goal net fence 25 is soccer goal 2
It is configured by stretching a goal upper net 27 on a wider goal upper frame 26. The upper goal frame 26 is formed of a pipe material similar to the upper frame body 8 and has a reinforcing frame 28 formed of a wire material having a diameter of 6 mm like the upper frame body 8. The goal upper frame 26 is detachably connected to the upper frame 8 by the connecting portions 29 located at the four corners thereof. Net on goal 2
The configuration of 7 is similar to that of the upper net 9. As a result, the on-goal net fence 25 is detachably supported on the goal-side net fences 3 located on both sides of the soccer goal 2.

As shown in FIGS. 4 and 5, the fence 1 is
It also has a side net fence 30 arranged along a side line (not shown). The side-side net fence 30 has almost the same structure as the goal-side net fence 3 with the upper fence 5 removed, and its height H ₃ is 2 m.
It is said. Therefore, in the drawings, the same parts are designated by the same reference numerals and the description thereof will be omitted.

Here, the lower frame 6 of the side net fence 30 has a width W ₃ of 2.5 m. The length of the leg member 16 and the stay 17 is shortened, and the stay 17 has a vertical portion 15
Is connected to approximately the middle part of. Therefore, when they are folded as shown by imaginary lines, they are placed within the height dimension of the side net fence 30 like the goal net fence 3. Therefore, there is no protruding portion when folded, and compact storage is possible.

The side net fences 30 are aligned and then integrally connected with the goal net fences 3. Further, at least one side net fence 30 is movable without being connected, and forms a door for entering and leaving the field.

When using the fence 1 having the above structure, the goal side and side net fences 3 and 30 are set up along the goal line and the side line, respectively. At this time, when performing the above-mentioned bound type mini soccer, arrange them on the line, and when performing formal futsal, increase the net fences 3 and 30 to largely surround the field (see FIG. 6). . This makes it possible to support any competition. In addition, when it is desired to remove the fence 1, the net fences 3 and 30 are carried to the storage location after the legs 14 are folded.

As described above, since the fence 1 is composed of the lightweight net fences 3 and 30 composed of the frame body and the net, and the leg portions 14 are provided to stand side by side, the fence 1 can be moved or installed / removed. It can also be installed in school grounds and multipurpose open spaces. This makes it possible to effectively use the space. Also, the legs 14
Since the net fences are provided on the back side, the net fences 3 and 30 can be completely adjacent to each other and can be prevented from protruding into the field.

Here, the goal side net fence 3 has its height H ₂ set to a relatively large value of 4 m in consideration of shooting mistakes and the like. Because it is lightweight, it is easy to carry. That is, the upper frame body 8 is made of a pipe material and is lighter than the lower frame body 6 made of an angle material. The pitch of the upper net 9 is made larger than that of the lower net 7, and the number of wire rods constituting the net is reduced to reduce the weight. The number of wires of the upper net 9 is small, and the tension applied to the upper frame 8 is relatively small, so that the structure can be realized. The upper and lower nets 9 and 7 are made of aluminum steel covered wire, which is lighter than ordinary wire rods.
Reduced the weight of.

Further, in the net fences 3 and 30 on the goal side and the side side, since the lower net 7 against which a relatively large number of balls hit is configured as described above, an appropriate repulsive force as if a cloth is stretched is applied to the lower net 7. In particular, in the case of a bound type competition, the irregular movement of the ball can be eliminated and the ball can be accurately rebounded. At the same time, it is possible to prevent permanent plastic deformation due to collision of the ball and the like, which also prevents irregular movement of the ball and enables the game to continue without hindrance. Here, as a condition of the net that produces such an effect, the tensile strength of the wire rod is 70 kg / mm ² or more, the wire diameter is 2.0 to 2.5 mm, and the pitch of the net, that is, the distance between the wire rods is 30 mm or less. confirmed. Although the pitch of the upper net 9 of the goal side net fence 3 is 50 mm and does not meet this condition, it does not cause a problem because the upper fence 5 mainly aims to prevent the ball from jumping out. Even so, the bounce of the ball is not as accurate as the lower fence 4, but is somewhat accurate.

Various modifications of the above embodiment can be considered.
For example, casters (wheels) may be attached to each net fence to allow traveling, and the net may be formed of chemical fiber instead of metal. The pitch of the net can be increased to, for example, 75 mm if the use in bound competition is not considered. Besides this, the present invention can be implemented in various modes.
