JP 05-106148 A ([0006], FIG. 1 etc.) Japanese Patent Laying-Open No. 2005-188164 ([0017], FIG. 1 etc.)

  However, a conventional partition net made of mesh yarn made of synthetic fiber filaments (hereinafter referred to as “synthetic fiber partition net”) has low cut resistance, and thus is formed of a conventional metal wire. Compared to partition nets (hereinafter referred to as “metal partition nets”), there is a problem that the net is easy to break and the deterrence of preventing outsiders from entering the site is small.

  On the other hand, the conventional metal partition net has a problem that the weight per unit area becomes heavier than the conventional synthetic fiber net.

  The present invention has been made to solve the above-described problems, and aims to provide a partition net capable of achieving both weight reduction and securing of cut resistance and a fence using the same. Yes.

Means for Solving the Problems and Effects of the Invention

  According to the partition net according to claim 1, since the hard portion is constituted by the first yarn including at least the composite yarn and the soft portion is constituted by the second yarn including at least the non-composite yarn, the conventional metal The weight per unit area can be reduced compared to a partition net made of metal. Moreover, since a hard part melt | dissolves a sheath part and the some 1st thread | yarn is mutually fuse | fused, compared with the partition net made from the conventional synthetic fiber, the cut resistance of a hard part can be improved. Therefore, there is an effect that it is possible to achieve both weight reduction of the partition net and cut resistance.

  Furthermore, the shape of the hard part can be easily maintained by fusing the first yarns together. Therefore, even when an external force is applied and the hard part is deformed, the hard part can be restored to its original shape after the external force is released.

  Further, the soft portion is continuously provided in the hard portion, and the content rate of the non-composite yarn with respect to the entire second yarn constituting the soft portion is greater than the content rate of the non-composite yarn with respect to the entire first yarn constituting the hard portion. Therefore, it is possible to easily deform the portion where the soft portion is disposed compared to the portion where the hard portion is disposed, and to easily maintain the deformed state. There is an effect that can be done. As a result, it is possible to easily install the partition net in a curved state according to the installation mode or to transport the partition net in a folded state.

Since the portion is disposed, the cut resistance of the ball-proof net can be secured. Therefore, there is an effect that it is possible to increase deterrence to prevent outsider intrusion into the predetermined area.

  According to the fence according to claim 9, in addition to the effect of the fence according to claim 8, the ball-proof net is constrained by the second horizontal wire installed along the horizontal direction below the first horizontal wire. Therefore, it is possible to prevent the ball-proof net from turning up due to a collision of a ball or the like. As a result, it is possible to prevent the ball or the like from turning up the ball-proof net and jumping out of the predetermined area.

  Further, since the second horizontal wire is installed below the first horizontal wire, that is, on the side close to the ground, it is possible to prevent an outsider from entering the predetermined area through the second horizontal wire. There is an effect that the deterrent to prevent can be increased.

  Moreover, since the soft part is arrange | positioned in the site | part restrained by the 2nd horizontal wire, a partition net can be made easy to wind a partition net along a 2nd horizontal wire. Therefore, there is an effect that the work of restraining the ball-proof net to the second horizontal wire can be performed efficiently.

  The lower net 60 and the skirt portion 70 are nets composed of a partition net 80 to be described later. Both side portions of the lower net 60 in the left-right direction (left-right direction in FIG. 1) are constrained by the vertical wire 31 and the upper net 60 ( A side end portion on the upper side of FIG. 1 is restrained by the dual-purpose wire 32 and restrained by the lower wire 34 at a height position away from the ground by a predetermined dimension.

  Here, with reference to FIG. 2, the partition net | network 80 which comprises the lower net | network 60 and the skirt part 70 is demonstrated. FIG. 2 is a front view of the partition net 80. In FIG. 2, in order to simplify the drawing and make the description easy to understand, a part of the partition net 80 is omitted, and the mesh yarns and meshes of the partition net 80 are schematically illustrated.

  As shown in FIG. 2, the partition net 80 covers a core portion made of a normal melting point fiber material made of polyester having a predetermined melting point and an outer peripheral surface of the core portion, and has a lower melting point than the normal melting point fiber material. A plurality of first yarns formed by combining a composite yarn having a sheath portion made of a polyester low-melting fiber material and a non-composite yarn usually made of a melting point fiber material; The composite yarn and the non-composite yarn are formed by combining the yarns, and the non-composite yarn content is set higher than that of the first yarn (that is, the composite yarn content of the whole is higher than that of the first yarn). A net formed by a plurality of second yarns (set low), a hard portion 81 which is a portion constituted by the first yarn, and a soft portion 82 which is a portion constituted by the second yarn, Has .

  When the partition net 80 is used as the lower net 60 (see FIG. 1), the hard portion 81 corresponds to a region surrounded by the plurality of wires 30 and a region constituting the skirt portion 70 when the fence 100 is viewed from the front. (See FIG. 1).

  The portion of the partition net 80 where the hard portion 81 is disposed is formed in a net shape as a whole by arranging a plurality of first yarns in a meandering manner with their portions abutting each other.

  Of the portion where the hard portion 81 is disposed, the side end portion on the lower side (lower side in FIG. 2) of the partition net 80 is formed in a band shape as a whole, and the plurality of first yarns are arranged in a straight line. It is installed.

  When the partition net 80 is used as the lower net 60, the soft portion 82 is a portion that is linearly disposed corresponding to a region constrained by the plurality of wires 30.

  That is, the soft portion 82 includes both the left and right side portions (parts in the left and right direction in FIG. 2) of the partition net 80, which are regions constrained by the vertical wire 31 (see FIG. 1), and the combined wire 32 (see FIG. 2). The side end portion on the upper side (upper side of FIG. 2) of the partition net 80 which is a part restrained by the lower wire 34 (see FIG. 1) and the lower side of the partition net 80 (see FIG. 1). 2 (lower side) and a portion located slightly above the side end portion.

  The portion of the partition net 80 where the soft portion 82 is disposed is formed in a net shape as a whole by arranging a plurality of second yarns in a meandering manner with their portions abutting each other.

  In addition, the side edge part in the upper part (FIG. 2 upper side) of the partition net | network 80 among the site | parts in which the soft part 82 is arrange | positioned is formed in the strip | belt shape as a whole, and several 2nd thread | yarn is arranged in parallel with linear form Has been.

  Here, the size of the partition net 80 in the left-right direction is set to be larger than the distance between the vertical wires 31, and the width dimension of the soft portion 82 (see FIG. 2 is set to a size larger than that of the soft portion 82 disposed in the other portion.

  In addition, among the portions where the soft portion 82 is disposed, the soft portion 82 disposed slightly above the side end portion on the lower side of the partition net 80 has a width dimension (a vertical dimension in FIG. 2). Is set to be larger than the outer diameter of the lower wire 34. Thereby, the dimension management of the partition net 80 can be easily performed.

  Here, a method for manufacturing the partition net 80 will be described. First, as a compounding process, a composite yarn and a non-composite yarn are combined to produce a plurality of first and second yarns.

  In the present embodiment, the normal melting point fiber material used for the composite yarn and the non-composite yarn has a melting point of 230 ° C. or more and 260 ° C. or less, and the low melting point fiber material used for the composite yarn has a melting point of 150. It is set within the range of not less than ℃ and not more than 180 ℃. Further, the fineness of the composite yarn and the fineness of the non-composite yarn are set to be equal, and the ratio of the core portion to the sheath portion in the composite yarn is set to 1: 1.

  Next, as the arranging step, the plurality of first yarns manufactured in the combining yarn step are arranged in parallel to the portion where the hard portion 81 is arranged, and the plurality of second yarns are arranged in parallel to the portion where the soft portion 82 is arranged. To do.

  At this time, the first yarn and the second yarn are arranged in a meandering manner so that a turtle-shell-like mesh is formed as a whole, and one first yarn or second yarn is placed on the other first side located on both sides thereof. It arrange | positions in the state contact | abutted alternately with the thread | yarn or the 2nd thread | yarn. In addition, a plurality of second yarns are arranged in a straight line in a state where the second threads are in contact with each other at the side end portion located on the upper side (upper side in FIG. 2) of the partition net 80, and the lower side (FIG. 2) in the partition net 80. A plurality of first yarns are arranged in a straight line on the side end portion located on the lower side in a state where they are in contact with each other.

  Next, as a forming step, the tenter is used to maintain the arrangement of the first yarn and the second yarn in the arrangement step, and is higher than the melting point of the low-melting fiber material and lower than the melting point of the normal melting fiber material. After heating at a temperature (eg, 200 ° C.), it is cooled.

  At this time, the first yarn and the second yarn are cured by being heated to melt the sheath portion of the composite yarn and then being cooled. In addition, one partition net in which the first yarn and the second yarn arranged in contact with each other are fused to each other through a melted sheath portion, and thereby the hard portion 81 and the soft portion 82 are continuously provided. 80 is molded.

  In the method of manufacturing the partition net 80 according to the present embodiment, when the first yarn and the second yarn are arranged in a meandering manner in the arranging step, the first yarn or The second yarn is alternately brought into contact with the other first yarn or the second yarn located on both sides of the second yarn by 5 courses per one place. The contact area between the yarn or the second yarn and the other first yarn or the second yarn may be set as appropriate.

  In this case, by increasing the contact area between one first yarn or second yarn and another first yarn or second yarn, one first yarn or second yarn and another first yarn or second yarn The fusing force with the two yarns can be strengthened.

  The partition net 80 thus formed is formed by the first yarn and the second yarn made of polyester, so that the weight per unit area is lighter than that of a conventional metal partition net, By curing the first yarn and the second yarn, the cut resistance of the hard portion 81 and the soft portion 82 can be increased, and as a result, the cut resistance can be made higher than that of a conventional synthetic fiber partition net. it can. Therefore, it is possible to achieve both weight reduction of the partition net 80 and cut resistance.

  The “weight per unit area” means a weight per unit area (for example, 1 m square) of the partition 80 in a normal use state (a state where the mesh of the ball-proof net 40 is widened).

  Furthermore, since the weather resistance of the partition net 80 can be improved by increasing the cut resistance of the hard portion 81 and the soft portion 82, the ball-proof net 40 is used when the partition net 80 is used as the ball-proof net 40. It is possible to extend the service life.

  Further, since the metal net is formed by knitting a metal wire, if a part of the wire is broken, a continuous net is likely to be generated in the vicinity thereof. On the other hand, the partition net 80 is integrally formed by fusing the first yarn and the second yarn together. Therefore, when a part of the first yarn or the second yarn is broken, its periphery It is possible to avoid the occurrence of continuous breakage.

  Returning to FIG. The first yarn constituting the hard portion 81 is set so that the content of the composite yarn with respect to the whole of the first yarn is higher than the content of the composite yarn with respect to the whole of the second yarn. It can be made easy to maintain the shape.

  Therefore, in the part of the partition net 80 where the hard portion 81 is disposed, even when an external force is applied and deformation is applied, the original shape is restored after the external force is released. Can be easy. Therefore, when the partition net 80 is used as the lower net 60 and the skirt portion 70, the partition net 80 can be prevented from sagging due to snow accumulation or the like.

  Further, when the partition net 80 is used as the lower net 60, the hard part 81 is disposed corresponding to the area surrounded by the plurality of wires 30 in the front view of the fence 100, thereby providing the cut resistance of the hard part 81. Can demonstrate creativity effectively.

  On the other hand, since the content rate of the composite yarn with respect to the whole of the second yarn constituting the soft portion 82 is set lower than the content rate of the composite yarn with respect to the entire first yarn, deformation is easier than with the hard portion 82. In addition, it is possible to easily maintain the deformed state.

  Therefore, when the partition net 80 is used as the lower net 60 and the skirt portion 70, the partition net 80 is curved along the portion where the soft portion 82 is disposed according to the installation mode of the lower net and the skirt portion 70. In addition to being able to be easily folded, the bent state and the folded state can be easily maintained.

  In the present embodiment, the content of the composite yarn with respect to the entire first yarn is set to 40%, and the content of the composite yarn with respect to the entire second yarn is set to 10%. The content of the composite yarn is preferably set to 15% or more and 60% or less.

  By setting the content of the composite yarn to 15% or more with respect to the entire first yarn, the cut resistance of the first yarn after melting the sheath portion of the composite yarn can be sufficiently ensured.

  Moreover, the stretchability of the 1st thread | yarn after fuse | melting the sheath part of a composite thread | yarn can be ensured by setting the content rate of the composite thread | yarn with respect to the whole 1st thread | yarn to 60% or less. As a result, when a tensile force is applied to the hard portion 81 composed of the first yarn in the collision of a person or a ball, the tensile force can be buffered by the expansion and contraction of the first yarn. 81 breaks can be suppressed.

  The upper net 50 extended above the combined wire 32 is composed of a synthetic fiber net, and has a weight per unit area larger than that of the partition net 80 used for the lower net 60 and the skirt portion 70. Lightly set. Therefore, the weight of the upper net 50 can be reduced as compared with the case where the entire ball-proof net 40 is configured from the partition net 80, and the burden on the support column 20 and the wire 30 can be reduced.

  Thereby, the installation space | interval of the some support | pillar 20 for constructing the some wire 30 which extends the upper net | network 50 can be set widely. Therefore, since the man-hour of the operation | work which embeds the support | pillar 20 in the ground and the operation | work which expands the upper net | network 50 to the support | pillar 20 can be reduced, while reducing the work burden at the time of installing the fence 100, Installation cost can be reduced.

  Further, when the fence 100 is provided between the ground where the ball game or the like is performed and the spectator seat, the number of the support pillars 20 can be reduced as compared with the case where a metal net is used for the fence, so that the fence 100 is in the spectator seat. When the spectator watches a ball game or the like performed on the ground, the range in which the sight line of the spectator is blocked by the support 20 can be reduced.

  Furthermore, compared with the case where the ball-proof net 40 is made of a metal net, it is possible to reduce the collision sound when a ball or the like collides with the ball-proof net 40 and the person who collides with the ball-proof net 40. Can be easily prevented from being injured or being damaged on the ball hitting the ball-proof net 40.

  Moreover, since the heat capacity of the ball-proof net 40 can be reduced as compared with a metal net, it is possible to easily avoid a burn caused by touching the ball-proof net 40.

  Next, with reference to FIG. 3, the restraining mode of the lower net 60 with respect to the vertical wire 31 will be described. 3A is a partially enlarged view of the fence 100 in the IIIa portion of FIG. 1, and FIG. 3B is a top view of the fence 100 viewed from the IIIb direction of FIG. 3A. In FIG. 3B, only the main parts are shown in order to simplify the drawing and make the description easy to understand, and the lower net 60, the support column 20, and the vertical wire 31 are schematically illustrated as the lower net 60. The partition net 80 used is viewed in cross section.

  As shown in FIGS. 3A and 3B, when the partition net 80 used as the lower net 60 is constrained to the vertical wire 31, both sides of the partition net 80 in the left-right direction (FIG. 3A left-right direction). The portion located on the inner side in the left-right direction with respect to the side end portion on both sides) is folded around the vertical wire 31 and the partition net 80 is fastened to the vertical wire 31 with a string (not shown) at the folded portion.

  Thereby, compared with the case where the side end part in the left-right direction of the partition net 80 is constrained to the vertical wire 31, it becomes easier to adjust the dimensional error between the dimension in the left-right direction of the partition net 80 and the separation interval of the vertical wire 31. Therefore, the dimension management of the partition net 80 can be easily performed.

  Further, the mesh of the lower nets 60 facing each other is aligned by folding, and the lower nets 60 facing each other in this state are bound with a string (not shown), thereby improving the aesthetics of the expanded lower net 60. be able to.

  In FIG. 3 (a), in order to simplify the drawing, the illustration of one lower net 60 of the two lower nets 60 that are overlapped by facing each other is omitted.

  Here, in the partition net 80 used as the lower net 60, the soft portions 82 are disposed on both sides in the left and right direction of the partition net 80, which is a portion restrained by the vertical wire 31. It is possible to easily wind the partition net 80 along. Furthermore, when the partition net 80 is tied to the vertical wire 31 with a string, the state in which the partition net 80 is wound around the vertical wire 31 can be easily maintained. Therefore, the work of restraining the partition net 80 to the vertical wire 31 can be performed more efficiently than the case where the portion where the hard portion 81 is disposed is restrained to the vertical wire 31.

  Moreover, since it can suppress trying to restore | restore to the shape before being wound around the vertical wire 31 by winding the site | part by which the soft part 82 is arrange | positioned among the partition nets 80 around the vertical wire 31, It is possible to prevent the restriction on the vertical wire 31 from being released.

  On the other hand, the hard part 81 is arrange | positioned in the site | part located between the site | parts restrained with respect to the two vertical wires 31 located in the right-and-left direction both sides of the partition net 80. FIG. Thereby, since the cut resistance which the hard part 81 has can be exhibited effectively, the penetration | invasion suppression force into the predetermined | prescribed area | region of the outsider by the lower net 60 can be heightened.

  Next, with reference to FIG. 4, the restraining mode of the lower net 60 with respect to the dual-purpose wire 32 will be described. FIG. 4 is a partially enlarged view of the fence 100 in the IV portion of FIG.

  As shown in FIG. 4, the lower net 60 is tightly bound by a string 61 in a state in which the side end portion on the upper side is wound around the dual-purpose wire 32.

  Here, since the partition net 80 used as the lower net 60 is provided with the soft portion 82 corresponding to the side end portion on the upper side thereof, that is, the portion constrained by the dual-purpose wire 32, the dual-purpose wire 32. The partition net 80 can be easily wound along the. Furthermore, when the partition net 80 is bound to the dual purpose wire 32 with the string 61, the state in which the partition net 80 is wound around the dual purpose wire 32 can be easily maintained. Therefore, as compared with the case where the portion where the hard portion 81 is disposed is constrained to the dual purpose wire 32, the work of constraining the partition net 80 to the dual purpose wire 32 can be performed efficiently, and an attempt is made to restore the original shape. It is possible to suppress the release of the state in which the partition net 80 is constrained by the dual-purpose wire 32 by the restoring force to be performed.

  On the other hand, since the hard part 81 is disposed in a part of the partition net 80 located below (the lower part of FIG. 4) than the part constrained by the dual-purpose wire 32, the cut resistance of the hard part 81 is provided. Can be effectively exhibited. Therefore, the deterrence which prevents the outsider intrusion into the predetermined area by the lower net 60 can be enhanced.

  Next, with reference to FIG. 5, the restraining mode of the lower net 60 with respect to the lower wire 34 will be described. FIG. 5A is a partially enlarged view of the fence 100 in a portion Va in FIG. 1, and FIG. 5B is a side view of the fence 100 viewed from the direction Vb in FIG. 5A. In order to simplify the drawing and facilitate understanding, only the main part is shown in FIG. 5B, and the lower net 60 and the lower wire 33 are schematically illustrated and used as the lower net 60. The partition net 80 is viewed in cross section.

  As shown in FIG. 5A, the lower net 60 is tightly bound to the lower wire 34 by a string 61 at a portion located slightly above the side end portion on the lower side (lower side in FIG. 5).

  Here, the partition net 80 used as the lower net 60 has a soft portion 82 at a portion located slightly above the side end portion on the lower side, that is, a portion corresponding to a position restrained by the lower wire 34. Since it is disposed, the partition net 80 can be easily deformed along the shape of the lower wire 34.
