Description

[Detailed description of the invention] [Field of industrial application] This invention relates to net fences installed in schoolyards, plazas, ball games stadiums, etc. This relates to a device that prevents the net attached to the device from loosening.

[Description of prior art] FIG. 3 shows an example of a conventional NetFence.

Between the adjacent pillars erected at a predetermined interval,
One wire 2 is stretched in a U-shape for each block. This wire 2 consists of a wire 2a stretched above between adjacent pillars 1, a wire 2b held down by a large number of wire bands 3 along the pillars 1, and a wire 2b stretched between the adjacent pillars 1 (GL). It consists of a wire 2c stretched along the line.

Both ends of this wire 2 (wire 2a and wire 2c
(each end of the wire 2b) is locked to another support 1 adjacent to the support 1 to which the wire 2b is attached. That is,
The end of the wire 2a is secured by a grip 5 wrapped around a band 4a attached to the upper part of the support column 1. Further, the end of the wire 2c is wrapped around a band 4b attached to the lower part of the same support column 1, and is attached to a grip 5.
It is locked in.

In this way, the wire 2 of this conventional network fence has grips 5 wrapped around its two ends.
The entire wire 2 is stretched by wrapping the wire around the wire and securing both ends of the wire. Then, the rope 7 around the outer periphery of the net 6 is tied to the wire 2 stretched in this way, and the net 6 is stretched.

[Problems to be solved by the invention] The above-mentioned NetFence has the following problems:
That is, by pulling each end of the wire 2a on the upper side and the wire 2c on the lower side together from both sides, the support 1
One wire 2 is stretched between them. However, the length of this wire 2 is long, and there is no means for holding the wire 2 in the middle of each side. Therefore, even if you think you have tensioned both ends sufficiently,
The wire 2 could not be fully resisted by the tensile force in the opposite direction due to its own weight, and the wire 2 could only be tensioned slightly loosely. Since the rope 7 around the outer periphery of the net 6 is tied to this slack wire 2, there is a problem in that the net 6 itself is stretched in a slack state. For this reason, when an external force (impact from a ball, wind force, etc.) is applied to this net 6,
This is also a factor that makes the network more likely to be damaged early.

[Purpose of the invention] This invention aims to provide a net fence in which the wires stretched between the supports are tightly tightened to eliminate slack in the wires, and the net attached to the wires is prevented from loosening. purpose.

[Means for solving the problem] In order to achieve the above-mentioned purpose, this invention stretches wires in a quadrilateral shape between a plurality of pillars erected at arbitrary intervals, and connects the outer periphery of the net to the wires. A net fence for attaching and stretching the net, wherein wrapping grips that are engaged and held by the pillars are wrapped around both ends of the wire stretched in a quadrilateral shape and near each bend of the wire, The wire is tightened to the support by securing each side of the wire.

[Example] Next, an example according to this invention will be described based on the drawings.

FIG. 1 is a front view showing one section of the NetFence according to this invention, and FIG. 2 is an enlarged view showing the essential parts of the NetFence shown in FIG.

Each of the pillars 1 erected at predetermined intervals has bands 10a,
10b is fixed. This band 10a,1
A thimble 14 for hanging the wire 12 is attached to each of the wires 0b.

In this embodiment, one wire 12 is wound around each thimble 14 placed above and below the adjacent pillars 1 and stretched in a quadrilateral shape. the wire 1
Both end portions 12y, 12z of the support column 1 are located near the thimble 14 attached to the band 10b of one of the struts 1, and the wrapping grip 5, which is engaged with the thimble 14, is attached to the end portions 12y, 12z. They are tightened separately and held by pulling the wire 12 from both sides.

One of the wires 12a on the lower side of the wire 12 is held at the end 12y by the winding grip 5, but the other side (near where the wire 12 is bent) is attached to another adjacent support 1. The band 10b is fastened to the band 10b via a thimble 14 with a wrapping grip 5, and tensioned by pulling from both sides. Moreover, the wire 12b on the upper side is also connected to each band 10a of the adjacent support 1.
It is held and tightened from both sides by the wrapping grip 5 via the thimble 14 of the thimble 14.

On the other hand, the wire 12 is a wire 12c along the support 1.
is held down with a large number of wire bands 16 so as not to shift.

According to the network fence of the embodiment, the wires 12 on the upper and lower sides, which tend to loosen due to their own weight, etc.
a, 12b and the wire 12c along the support 1 are pulled and tightened by a total of five wrapping grips 5, so each side can be tightened. Therefore, by tying the rope 7 around the outer periphery of the net 6 to this tensioned wire 12, the net 6 itself can be stretched without loosening.

In the above embodiment, a total of five winding grips 5 are attached to both ends of the wire 12 and near the bent portion thereof, but the present invention is not limited to this, and six or more grips may be used.

[Effects of the invention] As explained above, according to the NetFence according to this invention, there is a wire attached to the support at both ends of the wire stretched in a quadrilateral shape between adjacent support supports and near each bend of the wire. Since each side of the wire is secured by wrapping the supported wrapping grip around it, each side of the wire can be tightened to the support without loosening. Therefore, the net attached to this wire can also be stretched without loosening.
