Description

  The present invention relates to a security sheet that is installed at a place where an illegal intruder easily enters in a store or a residence and captures the intruder, and a method of using the security sheet.

  In recent years, incidents of illegal intrusion into stores and residences have frequently occurred. An illegal intruder may intentionally intrude through the entrance of a building, rather than bothering to open a building window. As an example of the invention for catching such an intruder, there is a security mat described in Patent Document 1.

  The crime prevention mat described in Patent Document 1 is configured by providing an adhesive layer b on the upper surface of the mat body a, and is used by being arranged in a warning area. According to Patent Document 1, this crime prevention mat, for example, for theft of high-end brand products such as precious metals, delays the criminal's actions and promotes a longer criminal time, It is said that by securing the express to the scene, the crime prevention effect will be enhanced, the retention of the evidence will be secured, and the investigation can be shortened.

JP-A-11-195179 (paragraphs 0007 to 0011, FIG. 1 and FIG. 2)

  The crime prevention mat described in Patent Document 1 is installed in a warning area (a doorway, a store entrance / exit, etc.) during a time zone during which illegal intrusion is likely to occur (at night, during a closed time of a store, etc.). On the other hand, this crime prevention mat is generally removed during a time period during which intrusion is unlikely to occur (daytime, store opening hours, etc.). Furthermore, a visitor mat is also installed in a warning area where a security mat was installed. This is because the security mat is intended to catch illegal intruders and should not catch those who are clearly not illegal intruders (residents, visitors, etc.).

  However, when such an operation for installing and removing such a security mat is performed on a daily basis, an intruder may be alarmed by seeing an object installed in the alert area.

  This invention is made | formed in view of said point, and it aims at providing the instrument for crime prevention which an intruder is hard to watch.

  The crime prevention sheet of the present invention includes a base layer sheet provided with a design pattern on the upper surface, and a pressure-sensitive adhesive sheet having translucency and laminated on the upper surface of the base layer sheet.

  The method of using the security sheet of the present invention includes a first step of installing the security sheet in a predetermined warning area, and a second step of installing an installation object having the same pattern as the design pattern on the upper surface in the warning area. Steps are alternately performed.

  ADVANTAGE OF THE INVENTION According to this invention, an intruder can perceive a design pattern permeate | transmitting an adhesive sheet, and can make an illusion as if a security sheet is installation objects, such as a visitor's mat | matte. That is, it is possible to provide a crime prevention device that is difficult for an intruder to watch.

It is a top view of the store where the security sheet was installed. It is a top view of a security sheet. It is a side view of a security sheet. It is an example of a design pattern. It is an example of a design pattern. It is an example of a design pattern. It is a side view which shows another usage method of a security sheet.

  One embodiment will be described with reference to FIGS. In this embodiment, an application example to the security sheet 101 installed in the store 201 will be described. FIG. 1 is a plan view of a store 201 in which a security sheet 101 is installed.

  The security sheet 101 is a flexible sheet having a rectangular shape in plan view. As an example, the security sheet 101 has a horizontal width of 690 mm and a vertical width of 410 mm. This crime prevention sheet 101 is installed in a warning area 202 where illegal intruders are likely to enter in a time zone in which illegal intrusion is likely to occur for crime prevention of stores 201 such as business establishments and convenience stores. For example, in the store 201, the vicinity of the door 203 serving as an entrance to the store 201 is a warning area 202. Therefore, the security sheet 101 is installed in the vicinity of the door 203 after the store 201 is closed. As another example, the security sheet 101 can also be used for crime prevention for a residence. In this case, it is installed at the entrance when all the residents in a general residence go on a trip or at midnight when the residents are asleep.

  FIG. 2 is a plan view of the security sheet 101. The security sheet 101 includes a base layer sheet 102 and an adhesive sheet 103.

  The base layer sheet 102 is made of a rubber material such as nitrile rubber (NBR) and is formed into a flat sheet shape. As another embodiment, the base layer sheet 102 may be formed of a material other than rubber, for example, a resin material such as a synthetic resin.

  The pressure-sensitive adhesive sheet 103 is formed in a flat sheet shape using a light-transmitting material. As an example, the adhesive sheet 103 is formed of polyethylene terephthalate (PET). The pressure-sensitive adhesive sheet 103 is laminated on the upper surface 102 a of the base layer sheet 102 and fixedly attached to the base layer sheet 102. The pressure-sensitive adhesive sheet 103 extends on the upper surface 102a of the base layer sheet 102 from the edge to almost the entire remaining region with the margin 104 left. As another embodiment, the pressure-sensitive adhesive sheet 103 may be laminated on a part of the upper surface 102 a of the base layer sheet 102.

  FIG. 3 is a side view of the security sheet 101. Please refer to FIG. 2 and FIG. A design pattern 105 is provided on the upper surface 102 a of the base layer sheet 102. An example of the design pattern 105 will be described later with reference to FIGS. The design pattern 105 is printed on the upper surface 102a of the base layer sheet 102 by a method such as silk screen printing or painting using an air brush, for example, using ink containing a silicone-based material. The design pattern 105 occupies almost the entire remaining area with the margin 104 left from the edge on the upper surface 102 a of the base layer sheet 102.

  On the lower surface 102b of the base layer sheet 102, fine irregularities 106 for preventing slipping are formed.

  A highly viscous adhesive 107 having translucency is applied to the upper surface 103 a of the adhesive sheet 103. As this adhesive 107, for example, a material containing polybutene can be adopted.

  Incidentally, the security sheet 101 further includes a protection sheet 108. The protective sheet 108 is a flexible sheet having a rectangular shape in plan view, and is formed of a material that can be peeled off from the adhesive 107. The protective sheet 108 is made of, for example, silicone rubber. A sticky substance such as an adhesive is not applied to both surfaces of the protective sheet 108.

  The protective sheet 108 is large enough to cover the adhesive sheet 103. This protective sheet 108 is laminated on the upper surface 103 a of the adhesive sheet 103. A male snap button 109 is attached to the end of the protective sheet 108. The male snap button 109 is fitted to the female snap button 110 attached to the margin 104 of the base layer sheet 102, and the base layer sheet 102 and the protective sheet 108 are detachably attached. Here, the male snap button 109 and the female snap button 110 constitute an attachment portion 111 for detachably attaching the protective sheet 108 to the base layer sheet 102. As shown in FIG. 2, the attachment portion 111 is provided side by side along one side of the security sheet 101.

  4 to 6 are examples of the design pattern 105. FIG. As the design pattern 105, any of a carpet pattern as shown in FIG. 4, a tatami pattern as shown in FIG. 5, and a surface pattern of a needle punch carpet as shown in FIG. 6 can be adopted. In addition, the pattern used for the design pattern 105 is not restricted to these, What is necessary is just the pattern normally used for the floor surface of the store 201 or a residence. And the design pattern 105 is provided in the upper surface 102a of the base layer sheet | seat 102 by printing the image data (for example, image data of carpet pattern) obtained by imaging | photography.

  Please refer to FIG. 1 and FIG. A method of using the security sheet 101 will be described. A store clerk (not shown) installs the security sheet 101 in the alert area 202 of the store 201 during a time zone during which illegal intrusion is likely to occur (at night, during a closed time of the store, etc.). Then, the clerk removes the security sheet 101 from the warning area 202 in preparation for a visitor when a time zone (daytime, during the business hours of the store, etc.) where it is difficult for illegal invasion comes. Then, the store clerk installs an installation object 301 in which the same pattern as the design pattern 105 provided on the crime prevention sheet 101 is provided on the upper surface in the alert area 202.

  Here, when the security sheet 101 is removed, the store clerk fits the male snap button 109 to the female snap button 110 to attach the protective sheet 108 to the base layer sheet 102, and covers the adhesive sheet 103 with the protective sheet 108. Thereby, the salesclerk can remove the security sheet 101 without touching the adhesive sheet. On the other hand, when installing the security sheet 101, the store clerk separates the male snap button 109 and the female snap button 110, peels off the protective sheet 108, and exposes the adhesive sheet 103.

  In this way, the store clerk installs the security sheets 101 and the installation objects 301 alternately in the alert area 202 every day. When the security sheet 101 is used in this way, an intruder visually recognizes the design pattern 105 that can be seen through the translucent adhesive sheet 103, and the security sheet 101 is installed on a daily installation object 301. There is a high possibility of illusion as if there is. For this reason, the probability that an intruder steps on the adhesive sheet 103 of the crime prevention sheet 101 without warning is increased. The adhesive 107 strongly adhered to the bottom of a shoe (not shown) worn by the intruder captures the intruder. As a result, the intruder is rampant and illegal intrusion is easily detected. Even if the intruder escapes from the adhesive 107, the adhesive 107 attached to the bottom of the intruder's shoes sticks to the floor around the alert area 202 in the store 201. For this reason, the intruder can be easily identified.

  FIG. 7 is a side view showing another method of using the security sheet 101. When a store clerk installs an installation 301 for a visitor during a time zone during which intrusion is difficult to occur (daytime, business hours of the store, etc.), the adhesive sheet 103 of the security sheet 101 installed in the security area 202 It is also possible to stack the protective sheet 108 on the upper surface 103 a and to install the installation object 301 on the upper surface 108 a of the protective sheet 108. According to this method of use, the store clerk does not need to remove the security sheet 101 from the warning area 202 in a time zone in which illegal intrusion hardly occurs. Furthermore, it is not necessary to provide a storage space in the store 201 for storing the security sheet 101.
