Description

  The present invention relates to a blindfold fence structure capable of easily performing blindfolding on a fence made of a wire mesh, a fiber mesh, a vertical rail, or the like.

  The fence has various functions, and is generally installed with emphasis on the function. For example, as fences for defining the boundary of a site, a mesh fence made of a wire mesh or a fiber mesh with a coarse mesh, or a vertical fence made of vertical bars with a wide interval is used. On the other hand, in order to protect privacy within a site or a building, a blindfold fence made of a fine lattice is used (Patent Document 1).

  However, when a wire mesh fence is installed simply to define the boundary of the site, secret matters may be implemented on the site. For example, when conducting research and development of large vehicles, heavy machinery, etc. on the premises, it is possible to visually check the state of vehicles, heavy machinery, etc. from the outside with a wire mesh fence, and there is a risk of knowing the development status. In such a case, the wire fence must be removed and a blindfold fence must be installed. However, such means have the disadvantage of being expensive. In addition, it is also known to stretch a vinyl sheet on a wire mesh fence to make a blindfold (Patent Document 2). was there. In addition, the vinyl sheet is not well-lighted and the site is dark.

That is, the present invention is a blindfold fence structure comprising a fence and a sheet stretched on the fence, the sheet is a warp knitted surface fabric in which eyes are formed between adjacent stitch rows knitted in the wale direction, A double knitted fabric comprising a lining having a stitch row at a position corresponding to the eyes, and a connecting yarn connecting the stitch row of the warp knitted fabric and the stitch row of the lining, and exists in the eye The present invention relates to a blindfold fence structure characterized by being difficult to see through from the eyes by the connecting yarn and the stitch row of the lining.

  As the fence used in the blindfold fence structure according to the present invention, a conventionally known fence can be adopted, but in general, a wire mesh fence made of a wire mesh having a coarse mesh or a wide interval so that the inside of the site can be seen through. A vertical rail fence made of vertical rails is used. The present invention is characterized by a sheet stretched on the fence.

  The sheet used in the present invention comprises a double knitted fabric. The double knitted fabric is generally knitted by a double raschel knitting machine, and is composed of a warp knitted surface fabric, a lining fabric, and a connecting yarn. In this drawing, the black color is the warp knitted surface, the white color is the lining, and the line is the connecting yarn. The warp knitted outer fabric is composed of stitch rows 1a, 1b, 1c, 1d... Knitted in the wale direction, and between adjacent stitch rows 1a and 1b, 1b and 1c, 1c and 1d. To form knot portions 1ab, 1bc, 1cd... And eyes 4. The lining has a stitch row at a position corresponding to this eye 4.

  As shown in FIG. 1, the lining may be the same type of warp knitted fabric as the warp knitted fabric. That is, it consists of stitch rows 2a, 2b, 2c, 2d... Knitted in the wale direction, and the adjacent stitch rows 2a and 2b, 2b and 2c, 2c and 2d. A warp knitted lining in which the knot portions 2ab, 2bc, 2cd... Are formed and the eyes are formed may be used. The lining has stitch rows 2a, 2b, 2c, 2d,... At positions corresponding to the stitches 4 of the warp knitting surface. The connecting yarn 3 is entangled with each stitch in the stitch rows 1a, 1b, 1c, 1d... Constituting the warp knitted fabric, and the lining stitch row existing at a position corresponding to the eye of the warp knitted fabric. 2a, 2b, 2c, 2d... A state in which the connecting yarn 3 is present only in a part of the upper left in FIG. 1 is schematically shown. That is, the connecting yarn 3 entangled with the stitches of the warp knitted stitch row 1a is entangled with the stitches of the knitted stitch row 2b. The connecting yarn 3 entangled with the stitches of the stitch row 2b is entangled with the stitch row 1c of the warp knitted fabric, and the stitches formed on the warp knitted fabric are sequentially repeated in the wale direction. It will be in the state shielded by the connecting thread 3. FIG. 2 is an end view taken along line AA of FIG. 1 and shows the presence state of the connecting yarn 3 at the knot portion of the warp knitted surface and the knot portion of the lining. Since the adjacent stitch rows are united at the knot portion, the connecting yarn 3 has a relatively regular zigzag shape.

  Further, as shown in FIG. 3, the lining may be a row of chain knitting yarns different from the warp knitting surface. That is, the stitch row may be a chain knitting yarn or a row of chain knitting yarns 2'a, 2'b, 2'c, 2'd. This chain of chain knitting yarns 2'a, 2'b, 2'c, 2'd ... exists at a position corresponding to the eye of the warp knitted surface. The connecting yarn 3 is entangled with each stitch in the stitch rows 1a, 1b, 1c, 1d... Constituting the warp knitted fabric, and the lining stitch row existing at a position corresponding to the eye of the warp knitted fabric. 2'a, 2'b, 2'c, 2'd... A state in which the connecting yarn 3 exists is schematically shown only in a part of the upper left in FIG. That is, the connecting yarn 3 entangled with the stitches of the stitch row 1a of the warp knitted outer fabric is entangled with the stitches of the knitted stitch row 2'b of the lining. The connecting yarns 3 entangled with the stitches of the stitch row 2'b are entangled with the stitch row 1c of the warp knitting surface material, and the stitches are formed in the warp knitting surface material by proceeding in the wale direction and repeating sequentially. Is shielded by the connecting yarn 3. FIG. 4 is an end view taken along line BB in FIG. 2 and shows a state in which the connecting yarn 3 exists between the knot portion of the warp knitted surface and the chain stitch yarn of the lining. The connecting yarn 3 entangled with the chain knitting yarn 2'a is entangled with the knot portion bc including the stitch row 1b, and then entangled with the chain knitting yarn 2'c. It is entangled with chain stitch yarn.

  Conventionally known monofilament yarn, multifilament yarn, spun yarn or the like is used as the yarn for forming the warp knitted surface and the lining. The color of the thread may be any color such as white, black, or red, but is preferably black with a high blinding effect. Specifically, an original multifilament yarn containing carbon black is preferable. As the connecting yarn, conventionally known monofilament yarn, multifilament yarn, spun yarn or the like is used, and it is preferable to use multifilament yarn. This is because the multifilament yarn is formed by converging a plurality of filaments, and when this is used as a connecting yarn, the filaments are scattered to improve the blinding effect. Moreover, although the raw material of the thread | yarn to be used is also arbitrary, it is preferable to use the thread | yarn which consists of a polyethylene terephthalate. Since polyethylene terephthalate has excellent weather resistance, it is optimal as a material for a blindfold fence structure installed outdoors.

  The double knitted fabric having the above configuration is stretched along a wire mesh fence or a vertical rail fence. In order to stretch, a double knitted fabric may be tightly bound to a fence post or the like. In order to facilitate the double knitted fabric along the wire mesh fence or the like, the double knitted fabric may be provided with rigidity. For this purpose, as the yarn constituting the warp knitted surface or lining, a multifilament yarn made of a core-sheath composite filament in which the core component is a high-melting polymer and the sheath component is a low-melting polymer is used, and only the sheath component is used. The filaments may be bonded by heating and melting. In addition, it is good also as a blindfold sheet | seat for privacy protection or a secret information leakage prevention, using double knitted fabric independently without attaching to a fence.

  The blindfold fence structure according to the present invention has a structure in which a specific double knitted fabric is stretched on the fence. And since the eyes are shielded by the connecting yarn, the double knitted fabric is difficult to see through the site and can exhibit a blinding effect. In addition, since there is a gap between the connecting yarns, air permeability is good, and the fence is less likely to fall even under strong winds, and there is a certain degree of lighting. Furthermore, since the blindfold fence structure according to the present invention is simply stretched on the installed wire mesh fence or the like, the blindfold can be realized at low cost.
