このクリ−プ係数τは、弾性率と粘性係数に依存し、粘着剤のベ−スポリマ−、軟化剤、粘着付与剤の種類や配合量によって調整できる。
【００１０】
本発明に係る防犯用マットを警戒領域に配置すれば、犯行者が侵入しても防犯用マットで足を捕られて犯行が遅れるから、センサ−の作動や防犯カメラ等で異常を通報された警備員や警察官が犯行者の逃亡前に現場に到着して犯行者を現行犯で捕捉できる。
例え、犯行者が逃亡しても、防犯用マットの粘着剤層についた足跡が長時間かけてクリ−プ変形を完結し、犯行後数時間後では足跡がまだクリ−プ変形中であって充分に痕跡が残されており、また、靴、衣服の布屑や頭髪等の前記粘着剤層への付着も充分に期待できるので、これらの遺留物から迅速な捜査が可能となる。 本発明において使用する粘着剤の粘度は、余り高くするとタック力が不足し、余り低くすると流動性が増し足跡等の痕跡が早期に消失してしまうので、１×１０⁵ポイズ以下、特に１×１０³〜１×１０⁵ポイズとすることが好ましい（ただし、加熱温度６０℃、荷重３０ｋｇ、ノズル径１ｍｍ、長さ１ｍｍのもとでフロ−テスタ−により測定した粘度）。
また、粘着剤層の厚さは厚くすればするほど、犯行者が足を粘着剤層から引き離そうとするときの粘着剤の糸曳きがそれだけ強くなり、脱離に時間がかかることになるが、逃亡を２〜３分程度遅らせ得れば、犯行者の逃亡前の警備員の現場到着が充分に可能であり、０．５〜１０ｍｍ、特に３〜５ｍｍとすれば充分である。
【００１１】
上記粘着剤においては、ベ−スポリマ−１００重量部、軟化剤３０〜２００重量部、粘着付与剤５０〜３００重量部を主体とし、熱老化防止剤や紫外線防止剤数部を添加し混練して調製される。酸化劣化を生じ易い場合は、窒素ガス、炭酸ガス等の不活性ガスで混練装置内をガス置換するか、連続パ−ジしつつ混練される。
ベ−スポリマ−としては、ゴム、ホットメルト系ポリマ−またはアクリル樹脂を使用でき、ホットメルト系ポリマ−としては、ＳＩＳ、ＳＢＳ、ＳＥＰＳ、ＳＥＢＳ等の熱可塑性ゴムを使用できる。
上記軟化剤は、粘着剤のＴｇを低下させ、低温時における流動性を高め、タックを保持させるために使用され、プロセスオイル、エキステンダ−オイル等の石油系軟化剤やポリイソブチレン、ポリブテン、液状ポリイソプレン等の液状ゴムや二塩基酸エステル系可塑剤等の合成可塑剤等を使用できる。
上記ベ−スポリマ−がゴム弾性体であっても、軟化剤がベ−スポリマ−に良く相溶し、ゴム組織内に均一に分散されてゴム弾性体の結合が緩和されゴム弾性体分子相互がすべりあって良好な塑性変形性が期待でき、または、軟化剤がゴム弾性体の組織内にコロイド粒子となって分散介在し、ゴムの三次元構造が滑り易くなることが期待できる結果、粘着剤の前記クリ−プ性を充分に確保できる。
上記粘着付与剤には、ロジン、ロジン誘導体、ポリテルペン樹脂、テルペンフェノ−ル樹脂、石油系樹脂、クロマン−インデン樹脂等を使用できる。
【００１２】
本発明に係る防犯用マットは、マット本体上面を離型処理し、この離型処理面に粘着剤を塗布した構成とすることもできる。この剥離処理は、長鎖アルキル基を有するポリマ−、フッ素原子を含む化合物やポリマ−、シリコ−ン系ポリマ−等の剥離剤を塗布することにより行うことができる。
この構成の防犯用マットによれば、犯行者がマット上を歩こうとすると粘着剤層がマット本体から剥がれて足にまとわりつき、更に歩こうとするとそのまとわりつきが拡大して歩行が困難になり、逃亡を遅らせることができる。また、マット本体をリサイクルできる利点もある。
また、図２に示すように粘着剤層ｂの裏面に支持シ−トａ”、例えばプラスチックシ−トを一体に設けたものをマット本体ａ上に載置することもでき、この場合も上記と同様、まとわりつきによる逃亡の遅延、マット本体のリサイクルの利益を得ることができる。
【００１３】
上記何れの防犯用マットにおいても、粘着剤層表面に剥離紙を当てがって運搬、保管などの取扱いを行うことが好ましく、図１及び図２において、ｆは剥離紙を示している。
上記何れの防犯用マットにおいても、粉末または液状の防犯着色剤を内蔵したカプセルまたは易破壊性の袋を粘着剤層に点在させておくことができ、この場合、犯行者が防犯用マットを踏むとカプセルまたは易破壊性の袋が破れて防犯着色剤が靴、足、衣服等に付着するので犯行者の特定が容易になる。
【００１４】
本発明に係る防犯用マットには、踏まれたことを検知する検知手段、例えば、加圧導電性ゴムセンサ−を組み込むことができる。
また、粘着剤に常時では非粘着性で加熱によって粘着性を発現する加熱型を使用し、マット本体にヒ−タと温度センサ−を組み込み、警戒セット期間中粘着剤層を所定の温度に加熱して粘着性を発現させることもできる。
また、粘着剤に常時は粘着性で冷却によって非粘着性となるものを使用し、マット本体に冷却パイプと温度センサ−を組み込み、警戒解除期間中粘着剤層を所定の温度に冷却して非粘着性にすることもできる。
本発明の請求項１０〜１３に係る警備システムは、これらのハイブリッド防犯用マットを使用しており、高級ブランド品を取扱う貴金属店舗等の警戒領域での窃盗行為を防止するのに使用される。
【００１５】
図３は請求項１０に係る警備システムの全体構成を示し、防犯用マット１と、扉・窓・シャッタ−等の開放を検出するマグネットセンサ−や人体が発する赤外線を検出する赤外線センサ−等の侵入センサ−及びガス漏れ検知器や火災検知器等の防災センサ−の複数個２，…と、警戒領域を利用者が所望する領域にセットまたは解除するのに使用されるモ−ド設定器３と、これらの機器からの信号に基づき警戒領域を監視する警報装置４と、通信回線５と、交換機６と、警備センタ−７とから構成されている。図３において、Ａは警戒領域を示している。
上記防犯用マット１には加圧導電性ゴムセンサ−１１を組み込んであり、侵入者がマットを踏むと、それを加圧導電性ゴムセンサ−１１が検知して検知信号を警報装置４に送出する。
上記モ−ド設定器３は、例えば、スイッチ、テンキ−、またはカ−ド（例えば、磁気カ−ド、ＩＣカ−ド等）とカ−ドリ−ダ−等とによって構成され、警報装置４に警戒セット信号または警戒解除信号を送出する。
上記警報装置４においては、防犯用マット１やセンサ−２の検知信号を受信し、異常判定したとき、または新たな設定モ−ドが設定されたときに通信回線５及び交換機６を介して当該異常信号や新たに設定された現在の警備モ−ド信号を遠隔の警備センタ−に送出する。
図４は上記警報装置４の機能ブロック図を示し、侵入者が防犯用マットを踏む自重により加圧導電性ゴムセンサ−１１が押圧されて踏み信号が入力される防犯用マットインタ−フェ−ス４１と、センサ−２による検知信号を入力するセンサ−インタ−フェ−ス４２と、警戒領域内の正常／異常を判断したりモ−ド設定器３の設定操作に応じて所望の設定モ−ドに設定したりする制御手段４３と、異常と判断されたときの異常信号または新たに警備モ−ドが設定されたときの警備信号を遠隔の警備センタ−７に送出する送信手段４４と、異常と判断されたときの異常表示を行ったり現状の警戒モ−ドを表示する表示手段４５と、上記の正常／異常の判断機能やモ−ド設定の判断機能等のプログラムが予め組み込まれたＲＯＭ４６と、現在の警戒モ−ド等を一時記憶するＲＡＭ４７とから構成されている。
【００１６】
上記警備システムの動作を図５に示すフロ−チャ−トにより説明すれば次ぎの通りである。
まず、警戒領域を最終に退出する者がモ−ド設定器３により警戒セットの操作を行う（ステップＳ１）。この警戒セット操作に基づいて警戒領域内の現状の保安状態、すなわち扉・窓等が完全に閉鎖されているか否かが判断される（ステップＳ２）。保安状態が完全であると判断されると、警戒セットに設定され（ステップＳ３）、警戒セット動作を終了する。
上記のステップＳ２において保安状態が不完全であると判断された場合、その旨が表示手段４５に表示される（ステップＳ４）。この場合は、前記最終退出者は表示に従い保安状態を完全にし、再度ステップＳ１の警戒セット操作を行う。上記のモ−ド設定器３が警戒領域内に設定されている場合は、最終退出者が侵入信号を発生させずに退出できるように、警戒セットの最終的な設定操作後、ディレ−タイマ−の作動で所定の遅れ時間後に警戒セットに設定される。
このようにして設定された警戒セット中に侵入者が防犯用マット１を踏むと、加圧導電性ゴムセンサ−１１の作動による異常信号が防犯用マットインタ−フェイス４１を介して制御手段４３に送入される（ステップＳ５）。制御手段４３では、現状の警戒モ−ドが警戒セット中であることをＲＡＭ４７から読み取り、顧客の識別コ−ドを付加して侵入異常信号（防犯用マット信号と特定した信号）が送信手段４４を介して遠隔の警備センタ−７に送信され（ステップＳ６）、これにて犯行が発生したことが警備員に通報される。
【００１７】
図６は請求項１１に係る警備システムの実施例のブロック図を示し、防犯用マット１に加圧導電性ゴムセンサ−１１の外に電熱ヒ−タ１２が組み込まれていること、及び警戒セットが設定されるとヒ−タ制御手段１３に駆動信号を送入する駆動手段４８が警報装置４に連結されていること以外は図３〜図４により説明した警備システムと実質的に同じ構成であり、ヒ−タ制御手段１３には、例えば、オン・オフスィッチと温度センサ−とにより自動的に所定の設定温度に設定されるものを使用できる。
図７はこの警備システムの動作を示すフロ−チャ−トであり、ステップＳ１１〜Ｓ１３とステップＳ１５は、図５のフロ−チャ−トにおけるステップＳ１〜Ｓ３とステップＳ５と同じである。図７におけるステップＳ１４で、警戒セットの設定に伴い制御手段４３から駆動手段４８を介してヒ−タ制御手段１３に駆動信号が送出され、ヒ−タ制御手段１３がこの信号を受信してヒ−タ１２を駆動し、防犯用マット１の粘着剤層が所定の温度に加熱されて粘着性を発現する。
この粘着性の発現後の防犯用マット１においては、粘着作用と加圧導電性ゴムセンサ−１１のために図３に示した警備システムの防犯用マット１と同様の機能を奏し、警備システムの警戒セット中の動作は図３に示した警備システムと実質的に同じである。警戒解除に伴い制御手段４３から駆動手段４８を介してヒ−タ制御手段１３に駆動停止信号が送出され、ヒ−タ１２の通電加熱が停止され粘着剤層が常温に冷却されて非粘着性とされる。従って、通常の通行が可能になる。
【００１８】
図８は請求項１２に係る警備システムの実施例のブロック図を示し、防犯用マット１に加圧導電性ゴムセンサ−１１及び電熱ヒ−タ１２の外に冷却パイプ１５が組み込まれていること、及び駆動手段４８に警戒セットが設定されるときにヒ−タ制御手段１３に駆動信号を送入する機能の外に警戒が解除されるときに冷却制御手段１４に駆動信号を送入する機能が付加されていること以外については図６で示した警備システムと実質的に同じ構成であり、冷却制御手段１４にコンプレッサ−やペルチェ素子を使用し、冷却パイプ１５内の水を冷却制御手段１４を経て循環させてある。このヒ−タ制御手段１３には、例えば、ペルチェ素子等のオン・オフと温度センサ−とにより自動的に所定の設定温度に設定されるものを使用できる。冷却時に冷却パイプ１５に直接水道水を供給して冷却することも可能である。
図９はこの警備システムの動作を示すフロ−チャ−トであり、ステップＳ２１〜Ｓ２５は、図７のフロ−チャ−トにおけるステップＳ１１〜Ｓ１５と同じである。
図９におけるステップＳ２７で警戒解除操作が行われると、ステップＳ２８でヒ−タ制御手段１３にヒ−タ−停止信号が送出されてヒ−タ１２が停止されると共に冷却制御手段１４に駆動信号が送出される。そして冷却制御手段１４がこの信号を受信して冷却パイプ１５内に冷水が供給され、防犯用マット１の粘着剤層が所定の温度に冷却され硬化されて非粘着性とされる。
【００１９】
本発明に係る防犯用マットは、上記した警備システムでの使用形態以外の形態でも使用できることは言うまでもない。
例えば、警備システムが警戒セット状態になった時点ではヒ−タの駆動は行わず、警備システムが侵入センサ−で侵入異常を検知した時にヒ−タ−を駆動して防犯用マットの粘着剤層を加熱して接着性を発現させれることもでき、これにより省電力化を図ることが可能である。

[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an example of a security mat according to the present invention.
In FIG. 1, a is a mat body, which can be a plastic injection-molded product, a cast-molded product, a rubber or plastic press-molded product, and the like, and is provided with a frame edge a ′ for preventing the flow of adhesive. The outer surface of 'is used as a taper surface so that it will not trip during normal walking. The mat body a is made of a rubber, plastic plate or plastic felt (for example, a pad with polyester fibers is punched by needle punching, and then the fibers are shrunk by hot water so as to be felt. It is also possible to use a material having a frame edge fixed to it by an adhesive or fusion.
b is an adhesive layer applied in the recess of the mat body a.
[0008]
The crime prevention mat according to the present invention is used by being arranged at a predetermined position in a warning area such as a precious metal store that handles high-end brand goods, and when an intruder steps on the mat, even if an attempt is made to separate the foot from the adhesive layer, immediately If the pressure-sensitive adhesive cannot be released and the adhesive is twisted and deformed to cause cohesive failure, the foot is detached from the pressure-sensitive adhesive layer. In this case, if the pressure-sensitive adhesive layer is made thicker, it becomes impossible to detach the foot from the pressure-sensitive adhesive layer for a longer time.
Further, when the offender steps on the security mat, the adhesive layer is compressed and deformed by the step load. Thus, the pressure-sensitive adhesive is a viscoelastic body, and is elastically deformed by the load and is viscously flowed and creep-deformed. In this case, if the step load is f, the elastic modulus is E, and the creep coefficient is τ. , The strain ε at time t is
[0009]
[Expression 1]

Can be evaluated.
The creep coefficient τ depends on the elastic modulus and the viscosity coefficient, and can be adjusted by the type and blending amount of the base polymer, softener, and tackifier of the adhesive.
[0010]
If the crime prevention mat according to the present invention is arranged in the warning area, even if a criminal invades, the crime will be caught by the crime prevention mat and the crime will be delayed, so the abnormality was reported by the operation of the sensor, the security camera, etc. Security guards and police officers can arrive at the scene before the criminal escapes and capture the criminal with the current criminal.
For example, even if the criminal escapes, the footprint on the adhesive layer of the security mat completes the creep deformation over a long period of time, and the footprint is still being deformed several hours after the crime. Since traces are sufficiently left and adhesion to the pressure-sensitive adhesive layer such as shoes, clothes cloths and hairs can be expected sufficiently, it is possible to quickly investigate these remains. If the viscosity of the pressure-sensitive adhesive used in the present invention is too high, tack force will be insufficient, and if it is too low, fluidity will increase and traces such as footprints will disappear at an early stage, so 1 × 10 ⁵ poises or less, especially 1 × It is preferable to be 10 ³ to 1 × 10 ⁵ poise (however, the viscosity measured by a flow tester under a heating temperature of 60 ° C., a load of 30 kg, a nozzle diameter of 1 mm, and a length of 1 mm).
In addition, the thicker the pressure-sensitive adhesive layer, the stronger the stringing of the pressure-sensitive adhesive when the offender tries to pull the foot away from the pressure-sensitive adhesive layer, which will take longer to detach. If the escape can be delayed by about 2 to 3 minutes, it is possible for the criminal to arrive on the spot before the escape, and 0.5-10 mm, especially 3-5 mm is sufficient.
[0011]
In the above-mentioned pressure-sensitive adhesive, 100 parts by weight of a base polymer, 30 to 200 parts by weight of a softening agent, and 50 to 300 parts by weight of a tackifier are added as main components, and several parts of a heat aging inhibitor and an ultraviolet light inhibitor are added and kneaded. Prepared. When oxidation deterioration is likely to occur, the inside of the kneading apparatus is replaced with an inert gas such as nitrogen gas or carbon dioxide gas, or kneading is performed while continuously purging.
As the base polymer, rubber, hot-melt polymer or acrylic resin can be used, and as the hot-melt polymer, thermoplastic rubber such as SIS, SBS, SEPS, SEBS can be used.
The softener is used to lower the Tg of the pressure-sensitive adhesive, increase the fluidity at low temperatures, and maintain tack, and is used for petroleum-based softeners such as process oil and extender oil, polyisobutylene, polybutene, liquid A liquid rubber such as polyisoprene or a synthetic plasticizer such as a dibasic acid ester plasticizer can be used.
Even if the base polymer is a rubber elastic body, the softening agent is well compatible with the base polymer and is uniformly dispersed in the rubber structure to relax the bonding of the rubber elastic bodies, so that the rubber elastic molecules interact with each other. As a result of sliding, good plastic deformability can be expected, or the softener can be expected to be dispersed in the form of colloidal particles in the structure of the rubber elastic body, and the three-dimensional structure of the rubber can be expected to be slippery. The above creep properties can be sufficiently secured.
As the tackifier, rosin, rosin derivative, polyterpene resin, terpene phenol resin, petroleum resin, chroman-indene resin and the like can be used.
[0012]
The crime prevention mat according to the present invention may be configured such that the upper surface of the mat body is subjected to a release treatment, and an adhesive is applied to the release treatment surface. This release treatment can be performed by applying a release agent such as a polymer having a long-chain alkyl group, a compound containing a fluorine atom, a polymer, or a silicone-based polymer.
According to the crime prevention mat of this configuration, when the criminal tries to walk on the mat, the adhesive layer peels off from the mat body and clings to the foot, and if he tries to walk further, the cling increases and walking becomes difficult. The escape can be delayed. There is also an advantage that the mat body can be recycled.
Further, as shown in FIG. 2, a support sheet a ", for example, a plastic sheet integrally provided on the back surface of the pressure-sensitive adhesive layer b can be placed on the mat body a. As with, you can benefit from delay in escape due to clinging and recycling of the mat body.
[0013]
In any of the above crime prevention mats, it is preferable to handle the product such as transportation and storage by applying the release paper to the surface of the pressure-sensitive adhesive layer. In FIGS. 1 and 2, f indicates the release paper.
In any of the above crime prevention mats, capsules containing powder or liquid crime prevention coloring agents or easily breakable bags can be scattered in the adhesive layer. When stepped on, the capsule or easily destructible bag is torn and the crime prevention colorant adheres to shoes, feet, clothes, etc., so that the criminal is easily identified.
[0014]
The crime prevention mat according to the present invention can incorporate a detecting means for detecting that it has been stepped on, for example, a pressurized conductive rubber sensor.
In addition, a heating type that is normally non-adhesive and exhibits adhesiveness when heated is used for the adhesive, heaters and temperature sensors are incorporated into the mat body, and the adhesive layer is heated to a predetermined temperature during the warning set period. Thus, tackiness can also be expressed.
Also, use a pressure-sensitive adhesive that is normally sticky and becomes non-tacky by cooling, incorporate a cooling pipe and temperature sensor into the mat body, and cool the pressure-sensitive adhesive layer to a predetermined temperature during the warning release period. It can also be tacky.
The security system according to claims 10 to 13 of the present invention uses these hybrid crime prevention mats and is used to prevent theft in a security area such as a precious metal store that handles high-end brand goods.
[0015]
FIG. 3 shows the overall configuration of the security system according to claim 10, such as a security mat 1, a magnet sensor for detecting the opening of a door, window, shutter, etc., an infrared sensor for detecting infrared rays emitted by the human body, and the like. A plurality of intrusion sensors and a plurality of disaster prevention sensors such as gas leak detectors and fire detectors, and a mode setting device 3 used to set or release the warning area in a desired area by the user And an alarm device 4 for monitoring a warning area based on signals from these devices, a communication line 5, an exchange 6, and a security center 7. In FIG. 3, A indicates a warning area.
The security mat 1 includes a pressure conductive rubber sensor-11, and when an intruder steps on the mat, the pressure conductive rubber sensor-11 detects it and sends a detection signal to the alarm device 4.
The mode setting device 3 includes, for example, a switch, a numeric keypad, a card (for example, a magnetic card, an IC card, etc.), a card reader, and the like, and an alarm device 4 Sends a warning set signal or a warning release signal.
In the alarm device 4, when the detection signal of the security mat 1 or the sensor 2 is received and an abnormality is determined, or when a new setting mode is set, the communication device 5 and the exchange 6 are used. An abnormal signal or a newly set current security mode signal is transmitted to a remote security center.
FIG. 4 is a functional block diagram of the alarm device 4, and a security mat interface 41 in which a pressure signal is input by pressing the pressure conductive rubber sensor 11 by its own weight when an intruder steps on the security mat. A sensor interface 42 for inputting a detection signal from the sensor-2, and a desired setting mode in accordance with a setting operation of the mode setting unit 3 for determining normality / abnormality in the warning area. A control means 43 for setting to the remote control center 43, a transmission means 44 for sending an abnormal signal when it is determined to be abnormal or a security signal when a new security mode is set to the remote security center 7, ROM 46 in which programs such as a display means 45 for displaying an abnormality when it is determined to display the current warning mode and a function for determining the normality / abnormality and a function for determining mode setting are incorporated in advance. And current vigilance - and a RAM47 Metropolitan for temporarily storing the de like.
[0016]
The operation of the security system will be described below with reference to the flowchart shown in FIG.
First, the person who finally exits the warning area operates the warning set by the mode setting device 3 (step S1). Based on this warning set operation, it is determined whether or not the current security state in the warning area, that is, whether the door / window, etc. are completely closed (step S2). If it is determined that the security state is complete, the alert set is set (step S3), and the alert set operation is terminated.
If it is determined in step S2 that the security state is incomplete, a message to that effect is displayed on the display means 45 (step S4). In this case, the last exiter completes the security state according to the display, and performs the warning set operation in step S1 again. When the mode setting device 3 is set in the warning area, the delay timer is set after the final setting operation of the warning set so that the final exit person can exit without generating an intrusion signal. Is set to the alert set after a predetermined delay time.
When an intruder steps on the security mat 1 during the warning set thus set, an abnormal signal due to the operation of the pressurized conductive rubber sensor-11 is sent to the control means 43 via the security mat interface 41. (Step S5). The control means 43 reads from the RAM 47 that the current alarm mode is in the alarm set, adds a customer identification code, and sends an intrusion abnormality signal (a signal specified as a security mat signal) to the transmission means 44. Is transmitted to the remote security center 7 (step S6), and the security guard is notified that a crime has occurred.

【Example】
[Example 1]
As the mat body, a rubber-based molded product having a length of 600 mm, a width of 1200 mm, a thickness of 5 mm, a frame edge width of 5 mm, and a height of 3 mm was used.
The pressure-sensitive adhesive includes 100 parts by weight of SEBS, 200 parts by weight of a tackifier (terpene), 120 parts by weight of a softener (petroleum), 5 parts by weight of a heat aging inhibitor (phenol), and an ultraviolet light inhibitor (amine). ) A hot melt pressure-sensitive adhesive obtained by melt mixing 2 parts by weight at a temperature of 170 ° C. was used, and the coating thickness was 3 mm. The viscosity of the adhesive (however, the viscosity measured with a flow tester under a heating temperature of 60 ° C., a load of 30 kg, a nozzle diameter of 1 mm, and a length of 1 mm) was 2.17 × 10 ⁴ poise.
[Example 2]
The same as Example 1 except that the coating thickness of the adhesive was 1.5 mm.
Example 3
The same as Example 1 except that the coating thickness of the adhesive was 0.3 mm.
When these examples were tested for release properties using new shoes, shoes with mud and shoes with water, the results were as follows.
[0021]
[Table 1]

[0022]
In Example 3 (pressure-sensitive adhesive layer thickness: 0.3 mm), when the shoes are wet, walking to some extent is possible, but if the number of arrangement locations is increased or the mat size is increased, the crime is temporally performed. It can be considerably delayed, and the object of the present invention can be sufficiently achieved.
Further, in the case of Example 1 (adhesive layer thickness 3.0 mm), it can be made completely unwalkable, and if the thickness of the adhesive layer is about 2 to 6 mm, it is arranged in one place with a normal mat size. Only by this, the object of the present invention can be achieved.
