Description

  The present invention relates to a traffic control tape that partitions off-entry or intrusion-prohibited areas such as crime scenes, fire scenes, dangerous places, and closed places.

  When an incident such as a murder occurs, police agencies prohibit the entry of people and vehicles other than those involved in the scene in order to preserve the crime scene. In the passage leading to the site, a no-entry tape is placed to partition the no-entry area and restrict the passage of people and cars.

  The off-limits tape is a long tape, and is stored in a police station with a length of several tens of meters wrapped around a core. When an incident occurs, police agencies bring a no-access tape wrapped around the core to the site, put an off-site tape on the passage leading to the site, and cut it to the required length. The width of the passage leading to the site and the length of applying the no-entry tape differ from site to site, and the required length of the no-entry tape varies.

  The same applies to off-limits tapes used by fire-fighting organizations at fire sites. The fire-fighting organization will bring the no-access tape wrapped around the core to the site, attach the no-access tape to the passage leading to the site, and cut it to the required length. The required length of off-site tape varies from site to site and varies.

  Note that a tape composed of a rope and a display sheet is disclosed in Patent Document 1, and a fabric tape is disclosed in Patent Document 2.

[Issues of background technology]
Traffic restriction tapes such as off-limit tapes are required to have mechanical strength against pulling and twisting in order to prevent breakage to the extent that a person messes around or pushes a car slightly. Moreover, since it is often used outdoors, weather resistance strength against sunlight, rain and wind is required. As a result, the traffic regulation tape has high strength and is very difficult for a person to cut by hand at the site. Therefore, the traffic regulation tape is brought to the site together with a cutting tool such as a scissors or a sword, and cut using the cutting tool. It takes time to carry the cutting tool with the traffic regulation tape.

[Idea for solving problems]
The traffic regulation tape is made of synthetic resin as the material or material. Then, it was considered that the synthetic resin tape can be easily cut by a human hand in the transverse direction. In the synthetic resin tape, hard protrusions were pressed against the edges to form minute portions with reduced strength, such as tears, cracks, and dents, and a point of strength reduction was provided. When this tape is to be torn by gripping both sides of the strength reduction point of the edge with fingers of both hands, tearing starts from the strength reduction point of the edge and is cut. It can cut without using a cutting tool on site. There is no need to carry cutting tools. The number of strength reduction points is one or more, and the plurality of strength reduction points are arranged at intervals in the transverse direction of the tape.

  In addition, the number of strength reduction points is set to a large number in the length direction of the tape, and they are arranged at intervals. This tape is cut by a human hand from a strength drop point at a position where it becomes a required length or a strength drop point at a position close to that position. Can be cut to the required length on site without using a cutting tool.

  Furthermore, as for the traffic regulation tape, the material of the synthetic resin tape, the cross-sectional dimension, the shape dimension of the strength reduction point, and the arrangement interval are selected to satisfy the required strength.

  Such a traffic regulation tape satisfies the required strength and can be cut by a human hand to a required length on site. The trouble of carrying the cutting tool can be saved.

1) In the traffic control tape that divides the area where entry or entry is prohibited,
The tape is made of synthetic resin,
At the edge of the tape, there are strength reduction points such as tears, cracks, dents,
There are many strength reduction points along the length of the tape.
The tape is characterized in that both sides of the strength reduction point are picked with fingers of both hands and cut from the strength reduction point.
2) In the above traffic regulation tape,
The strength reduction points are provided at the edge portions on both sides of the tape, respectively.

  The traffic regulation tape can be cut to the required length by a human hand at the site that divides the area where entry or entry is prohibited. The trouble of carrying the cutting tool can be saved.

[First example (see FIGS. 1 to 5)]
The traffic regulation tape in this example is a restricted access tape used by police agencies such as prefectural police and police stations at crime scenes.

  As shown in FIG. 1, the off-limit tape is a long tape 1 and is wound around a winding core 2. Labels 3 such as “no entry”, “KEEP OUT”, “XX prefectural police”, and “XX police station” are attached to the front and back sides of the tape 1, respectively. The signs 3 are arranged at regular intervals in the length direction of the tape 1.

  The tape 1 is made of a material or a synthetic resin sheet. The synthetic resin is made of polyolefin such as polyethylene or polypropylene. In the embodiment, polyethylene is used. The tape 1 has a width of about 50 to 100 mm and a thickness of about 0.05 to 0.2 mm. The length is several tens of meters.

  1 to 3, the tape 1 is formed with strength-reducing points 6 such as tears, cracks, and dents on both upper and lower edges, and a large number of strength-reducing points 6 are staggered. Is arranged. At each of the upper and lower edges, the strength reduction points 6 are single or plural in the transverse direction of the tape 1, and the plurality of strength reduction points 6 are arranged at regular intervals in the transverse direction of the tape 1. . Further, the strength reduction points 6 are a large number in the length direction of the tape 1 and are arranged at regular intervals. The strength reduction point 6 has a substantially rhombus or elongated shape, and the longitudinal direction is arranged in the transverse direction of the tape 1. The strength reduction point 6 has a length in the longitudinal direction of about 0.1 to 1 mm, an arrangement interval in the transverse direction of the tape 1 of about 0.2 to 5 mm, and an arrangement interval in the length direction of the tape 1 of 1 to 1. It is about 10 mm.

  When this inaccessible tape 1 is cut to a required length, the left and right side portions of the strength reduction point 6 at the position where the required length is reached or the strength reduction point 6 at a position close to that position are placed with fingers of both human hands. Pick and tear the left and right hands back and forth from the strength drop point 6 between the hands. There is no need for cutting tools such as spears and knives.

  When manufacturing the tape 1 of this example, the wide synthetic resin sheet S of a raw material is cut into a plurality of elongated tapes 1 through a slitter. A strength drop point 6 is formed on the synthetic resin sheet S when passing through the slitter.

  As shown in FIGS. 4 and 5, the slitter is provided with an upper roller 11 and a front roller 12 arranged in parallel. The synthetic resin sheet S sequentially passes through the upper roller 11 and the front roller 12. A blade 13 for cutting the wide sheet S into a plurality of narrow sheets and the tape 1 is provided at an intermediate position between the rollers 11 and 12. The blades 13 are arranged on the upper side of the cutting position of the wide sheet S, and are arranged at the same interval as the width of the tape 1 in the axial direction of the rollers 11 and 12. At the upper position of the upper roller 11, there is provided a protruding wheel 14 as a processing tool for forming a strength drop point, in which a large number of minute protruding blades protrude from the outer peripheral surface. The protruding wheel 14 has its axis parallel to the axes of the rollers 11 and 12. The protruding wheels 14 are arranged above the position of the wide sheet S at the edge of the tape 1 and are arranged at the same interval as the width of the tape 1 in the axial direction of the rollers 11 and 12.

  The wide synthetic resin sheet S passes between the upper roller 11 and the projecting wheel 14, and the blade of the projecting wheel 14 that is rotating is pressed during the passage, and the strength is reduced due to tearing, cracking, or dent. A minute portion, a strength reduction point 6 is formed. Thereafter, the synthetic resin sheet S passes through the lower side of the blade 13 and the front side of the front roller 12, and the blade 13 is pressed and cut into the plurality of tapes 1 when passing the blade position.

[Second example (see FIG. 6)]
In the traffic regulation tape of this example, the arrangement pattern of the strength drop points 6 is changed to “a grid pattern” instead of the “staggered pattern” in the first example. Other points are the same as in the first example.

  As shown in FIG. 6, the tape 1 of this example is formed with strength reduction points 6 such as tears, cracks, and dents on the upper and lower edges, and a number of strength reduction points 6 are formed in a grid pattern. Is arranged. In each of the upper and lower edges, a plurality of strength reduction points 6 are arranged in the transverse direction of the tape 1 and arranged at regular intervals. Further, the strength reduction points 6 are a large number in the length direction of the tape 1 and are arranged at regular intervals.

  In manufacturing the tape 1, a protrusion wheel having a “grid-like pattern” is used instead of the “staggered” pattern of protrusions on the outer peripheral surface of the protrusion wheel 14 in the first example.

[Third example (see FIG. 7)]
In the traffic regulation tape of this example, the material or material of the tape 1 is replaced with the “synthetic resin sheet S” in the first example, and “synthetic resin tube”. Other points are the same as in the first example.

  As shown in FIG. 7, the tape 1 of this example is formed by flatly folding a synthetic resin tube. The tape 1 has a structure in which two synthetic resin sheets are overlapped. The synthetic resin is made of polyolefin such as polyethylene or polypropylene. In the embodiment, polyethylene is used. The tape 1 has a width of about 50 to 100 mm and a thickness of about 0.05 to 0.2 mm.

  As in the first example, the tape 1 has strength reduction points 6 such as tears, cracks, and dents at the upper and lower edges, and a large number of strength reduction points 6 are arranged in a staggered manner. is doing. In order to form the strength reduction point 6 on the tape 1 in which the synthetic resin tube is flatly folded, the tape 1 is passed through the slitter in the first example, the blade 13 is not used, and the protruding wheel 14 is used on both sides. A strength drop point 6 is formed at the edge of the plate.
