Abstract

(57) [Summary] [Structure] A wire rope 4 is attached to the upper and middle portions of the four pillars 1, a wire net 3 is hung from the wire rope 4 via a coupling coil 5, and the wire rope 4 is turned at one end. The buckle and the winding grip are attached to the other end, and the wire mesh 3 is stretched. A turnbuckle is used at one end and a winding grip is used at the other end for the middle portion and the upper and lower wire ropes 4 as well, and the wire mesh 3 and the wire rope 4 are fixed at a predetermined interval with a binding wire or a C ring. The lower end of the wire net 3 is buried in the soil so that the balls cannot pass through the lower part. [Effect] By reducing the number of columns and minimizing the number of beams, it is possible to improve the workability such as column standing and tension.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a back net.

[0002]

[Prior art]

 The conventional back net shown in FIG. 2 is a column system which is generally adopted. (A) is a front view, (b) is a plan view, and (c) is a side view.

In the figure, 1 is a pillar, 2 is a beam, and 3 is a wire mesh. As shown in the figure, the distance between the columns 1 is 2 to 3 m, and the beams 2 are inserted in the vertical direction.

[0004]

[Problems to be solved by the device]

 Due to this structure, it is an obstacle for the spectators when viewed from the audience side. Moreover, since the number of columns 1 and beams 2 is large, there are difficulties in workability and economy.

An object of the present invention is to provide a back net that is easy to see without being obtrusive when viewed from the side of the audience.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the back net of the present invention has several beams arranged in an arc between at least two columns that control both ends of the back net, and at least the upper end portion of the columns is arranged. It is characterized in that it is connected by a wire rope, and a wire net is hung from the wire rope via a coupling coil so that the lower end portion of the wire net is buried in the soil.

[0007]

[Action]

 In the back net of the present invention, several beams are arranged in an arc shape between at least two columns that regulate both ends of the back net, and at least the upper ends of the columns are connected by a wire rope, and a coupling coil is connected to the wire rope. Since the wire net was suspended via the bridge and the lower end of the wire net was buried in the soil, the workability of pillar stands and ropes can be improved.

【Example】

 An embodiment of the present invention will be described below with reference to FIG. 1A is a front view, FIG. 1B is a plan view, FIG. 1C is a side view, and FIG. 1D is a detailed view of the wire rope 4 part. In these figures, the same parts as those in FIG. 2 are denoted by the same reference numerals, 4 is a wire rope, and 5 is a coupling coil.

In the present invention, in order to solve the conventional problems, the number of columns 1 is set to 2 to 5, and the use of the beams 2 is minimized to make it easy for the audience to see. That is, (1) This system is mainly composed of the pillar 1, the wire netting 3 and the wire rope 4. Then, the wire rope 4 is stretched on the upper end of the pillar 1, and the wire net 3 is hung on the wire rope 4 via the coupling coil 5. A turnbuckle is attached to one end of the wire rope 4 and a winding grip (neither is shown) is attached to the other end thereof, and the wire net 3 is stretched.

(2) A turnbuckle is used at one end and a winding grip is used at the other end for the intermediate portion and the upper and lower wire ropes 4, respectively.

(3) The wire netting 3 and the wire rope 4 are fixed with a binding wire or a C ring at a predetermined interval.

(4) The lower end of the wire net 3 is buried in the soil so that the balls cannot pass through the lower part.

In the embodiment shown in FIG. 1, the wire mesh 3 is an example of a diamond wire mesh. In the case of rhombus wire mesh, it is effective because the joints are not visible after completion because they are connected by column lines. The present invention is not limited to this shape, and a mesh (lattice) -shaped wire mesh can be adopted. As the material of the wire net 3, various kinds of materials such as plated wire have been conventionally used. However, by using a material having a higher strength than other wires such as an aluminum steel wire, the ball becomes the wire net 3 The amount of deformation when hit can also be minimized. In addition, the structure is such that the balls are buried in the soil so that the balls do not come out from the bottom, but the aluminum steel wire does not corrode in the soil and can withstand many years of use.

If the wire mesh 3, the wire rope 4, the coupling coil 5, and the like are made of a material that is advantageous in terms of corrosion resistance and strength, such as an aluminum steel wire, it is advantageous for maintenance.

[Effect of device]

 According to the present invention, the number of columns can be reduced and the number of beams can be minimized to improve the workability such as column standing and tug.
