Description

  The present invention relates to a sign and an alerting system, and more particularly to an indicator and an alerting system capable of alerting a traffic participant such as a pedestrian.

  Conventionally, a guard rail is installed at the boundary between the sidewalk and the roadway in order to prevent the pedestrian from entering the roadway from the sidewalk where the walker walks (see, for example, Patent Document 1).

JP 2002-69951 A

  However, since the guardrail is static, it did not actively alert pedestrians to suppress entry into the roadway.

  In view of the above points, the present invention provides a sign that can actively alert a traffic participant such as a pedestrian so as to suppress intrusion from one area to another area, and The purpose is to provide an alert system.

  The sign of the present invention is a sign installed on at least a part of a boundary partitioning one area where a traffic participant passes and another area, and the sign is a base end part installed on the boundary It has the part which the aspect extended with respect to changes.

  According to the sign of the present invention, the manner in which the sign installed on at least a part of the boundary that divides the one area where the traffic participant passes and the other area extends with respect to the base end portion changes. Has a part. For this reason, compared with the case where a sign does not have the aspect which changes with respect to a base end part, presence of the said boundary can be clearly recognized with respect to a traffic participant. As a result, it is possible to call attention to traffic participants so as to suppress intrusion from one area to another area.

  In the label of the present invention, it is preferable that the changing portion changes in a laterally extending manner with respect to the base end portion.

  In this case, the direction of the signs extending in the horizontal direction changes, so it is possible to effectively alert traffic participants to prevent intrusion into other areas from the side of the signs. It becomes.

  It should be noted that the changing aspect of the changing portion in the lateral direction with respect to the base end changes that the changing portion moves laterally with respect to the base end by an operation such as expansion, contraction, extension, extension, or rotation. It means that the aspect of the portion extending in the direction changes.

  In the label of the present invention, it is preferable that the changing portion has an upward extending manner with respect to the base end portion.

  In this case, since the extending aspect of the sign changes, it is possible to effectively alert the traffic participant so as to suppress intrusion into another area from above the sign. .

  It should be noted that the changing aspect of the portion that changes upward with respect to the base end changes that the portion that changes changes upward with respect to the base end by an operation such as expansion, contraction, extension, extension, or rotation. It means that the aspect of the extending part changes.

  A first alerting system of the present invention is an alerting system including a plurality of signs arranged in parallel at least at a part of a boundary partitioning one area where a traffic participant passes and another area. In addition, each of the signs has a portion in which a mode extending with respect to a base end portion installed at the boundary is changed.

  According to the first alerting system of the present invention, since a plurality of signs are juxtaposed along at least a part of a boundary that divides a region where a traffic participant passes and another region, The person passes through one area within the boundary defined by these signs and is guided not to enter another area.

  And since each sign has a portion that changes in the manner of extending relative to the base end portion installed at the boundary, compared to the case where the sign does not have a manner of changing relative to the base end portion, traffic participation Can clearly recognize the existence of the boundary. As a result, it is possible to effectively alert the traffic participants so as to suppress intrusion into other areas as compared with the case where the sign does not have such a portion.

  In the first alert system of the present invention, the system includes a detecting unit that detects an environmental change in the one region or the other region, and when the detecting unit detects an environmental change, the changing part is the extension. It is preferable that the aspect to perform changes.

  Further, in the first alerting system of the present invention, the system includes a detecting unit that detects an environmental change in the one region or the other region, and when the detecting unit detects an environmental change, the changing part is the It is also preferable to change the period in which the extending mode changes.

  In these cases, it is possible to effectively convey to the traffic participant that the environmental change has occurred in one area or the other area, and it is possible to further alert the traffic participant.

  Furthermore, in the first alert system of the present invention, when an environmental change in the one area or the other area is detected, a detection means for sending a detection signal, and the detection means can communicate with the detection means by wire or wirelessly. It is preferable to include a notification unit that is connected and issues an alarm when the detection signal is received from the detection unit.

  In this case, it is possible to issue an alarm from an informing means that can be installed at a location away from the area that an environmental change has occurred in one area or another area. Therefore, it is possible to convey to the traffic participants that are in the vicinity of the notification means installed in a place away from the region that the region is in such a situation, and to alert the traffic participants. Is possible.

  Furthermore, in the first alert system of the present invention, when an environmental change in the one area or the other area is detected, a detection means for sending a detection signal, and the detection means can communicate with the detection means by wire or wirelessly. It is preferable to include a lighting unit that is connected and lights up or blinks when the detection signal is received from the detection unit.

  In this case, it is possible to turn on or blink the lighting means that can be installed at a location away from the area, indicating that the environmental change has occurred in one area or the other area. Therefore, it is possible to convey to the traffic participants in the vicinity of the lighting means installed in a place away from the area that the situation is in such a situation, and to alert the traffic participants. Is possible.

  A second alerting system of the present invention is an alerting system comprising a plurality of signs arranged in parallel at least at a part of a boundary partitioning one area where a traffic participant passes and another area. Each of the signs has a portion extending in the direction of the sign adjacent to a base end portion installed at the boundary.

  A pole (sign) 1 and a warning system 10 according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, this alerting system 10 is a system including a plurality of poles 1 arranged in parallel. The plurality of poles 1 are installed on at least a part of the boundary of the sidewalk B that is adjacent to the roadway A and is an area where a pedestrian as an example of a traffic participant passes. The roadway A corresponds to another area of the present invention, and the sidewalk B corresponds to one area of the present invention.

  Each pole 1 is made of a resin, and is molded from a synthetic resin such as polyvinyl chloride or ABS. Since the pole 1 is made of resin, there is no problem even if a pedestrian makes contact. Furthermore, even if a pedestrian is sandwiched between the pole 1 and the vehicle, it is preferable for the pedestrian compared to a case where the pedestrian is sandwiched between the guard rail and the pole 1.

  However, the pole 1 is not limited to being made of resin, and may be made of a metal plate such as aluminum or steel and having a resin coated on the surface thereof. However, the pole 1 may be made of a hard material such as metal.

  The pole 1 has such a height that the pedestrian cannot straddle and does not give the pedestrian a feeling of pressure, for example, about 0.8 m to 1.2 m. The pole 1 has a base end 1a fixed to the ground by an anchor or the like.

  The pole 1 physically passes through the gap between the first pole 1b extending upward from the base end 1a and the adjacent pole 1 and protrudes from the sidewalk B into the road A. Or a second part 1c that is statically or psychologically disturbed.

  Pole 1 is made of red, orange, yellow and other conspicuous colors to call attention, and a red striped pattern with white on a red background and yellow with a black background to improve visibility. . In order to improve nighttime visibility, a reflective sheet or the like may be attached to the outer surface of the pole 1.

  The plurality of poles 1 are installed on at least a part of the boundary of the region from a predetermined portion B1 of the sidewalk B to another predetermined portion B2 of the sidewalk B. Here, the part B1 of the sidewalk B is a part connected to an entrance / exit C of a facility where people enter and exit, such as a factory, an office, a store, a park, or an apartment. And the part B2 of the sidewalk B is a part connected with the pedestrian crossing D provided in order for the pedestrian to cross the roadway A, for example.

  There is a roadway A in front of the entrance / exit C, and a pedestrian who has exited from the entrance / exit C has to walk along the sidewalk B for a while and cross the crosswalk C, and the parts B1 and B2 are separated from each other. .

  Under such circumstances, a plurality of poles 1 are installed at the boundary with the roadway A of the sidewalk B from the portion B1 to the portion B2. Further, a plurality of poles 1 are also installed on the part opposite to the part B2 from the part B1. The poles 1 are preferably installed at intervals at which pedestrians cannot pass, but are not limited thereto.

  In this way, a plurality of poles 1 are installed at the boundary of the sidewalk B from the portion B1 to the portion B2. For this reason, compared with the case where the pole 1 does not have the 2nd part 1c, a pedestrian can be made to recognize clearly the presence of the said boundary. Eventually, the pedestrian is alerted to walk in the area defined by these poles 1. Furthermore, since the pedestrian is guided to walk in this region, it is possible to suppress actions such as the pedestrian crossing the roadway A at a portion other than the pedestrian crossing D and jumping out of the roadway A.

  The alerting system 10 further includes a detection unit 2 that transmits a detection signal when an environmental change is detected, and a notification unit 4 that notifies an alarm when a detection signal is received from the detection unit 2.

  Here, at least one pole 1A among the plurality of poles 1 is provided with the detecting means 2. Specifically, the detection means 2 detects that a pedestrian has approached the pole 1A.

  More specifically, the pole 1B is provided with an infrared light source 3, the pole 1A is provided with an infrared sensor 2 comprising an infrared detector, and the infrared light emitted from the infrared light source 3 is detected by the infrared sensor 2 and is present between them. The presence or absence of a moving object is detected. And when the presence of an object is detected, it detects that the pedestrian existed between pole 1A, 1B.

  The detection means 2 is not limited to an infrared sensor, and may be a non-contact sensor such as a millimeter wave sensor or a contact sensor. Moreover, the detection means 2 is not limited to the case where it is arrange | positioned at the pole 1, You may arrange | position at the sidewalk B or the other installation thing installed in the periphery.

  Then, at least one pole 1C among the plurality of poles 1 is provided with an informing means 4 for notifying an alarm when the detecting means 2 detects that a pedestrian has approached. Here, the notification means 4 is connected to the detection means 2 so as to be communicable by wire or wireless. The notification means 4 is a warning light 4 arranged at the top of the pole 1C or the like, and when the detection means 2 detects that a pedestrian has approached and receives a detection signal transmitted, the warning light 4 is turned on or blinking. To do.

  In addition, although not shown in figure, the alerting | reporting means 4 is an alarm device arrange | positioned at the pole 1C, and when an alarm signal is received, an alarm device may emit an alarm sound. Moreover, the alerting | reporting means 4 may be a warning light and an alarm device. Moreover, the alerting | reporting means 4 is not limited to the case where it is arrange | positioned at the pole 1, You may be arrange | positioned at the sidewalk B or the other installation thing installed in the periphery.

  Thus, when the pedestrian approaches the pole 1A, the notification means 4 issues a warning. As a result, the pedestrian is alerted and hesitates to go out of the area demarcated by the pole 1, so that the pedestrian crosses the roadway A at a portion other than the pedestrian crossing D, or jumps into the roadway A. Further suppression can be achieved.

  Further, a pole 5 may be installed at a location apart from the plurality of poles 1 described above, and the notification means 4 may be provided on the pole 5. In the present embodiment, the pole 5 is installed on the sidewalk B located on the lower side of the roadway A adjacent to the sidewalk B.

  This notifies the driver of the vehicle traveling on the road A from the pole 5 existing on the upstream side of the pole 1 that the pedestrian has approached the boundary on the road A side of the sidewalk B divided by the plurality of poles 1. And can call attention.

  In addition, pole 1A-1C, 5 provided with the detection means 2 or the alerting | reporting means 4 is equipped with the storage battery as these power supplies. The storage battery may be a primary battery that is replaceably attached to the poles 1A to 1C, 5 or a secondary battery that is charged with power generated by a photovoltaic power generation panel installed on the outer surface of the poles 1A to 1C, 5. May be. The poles 1A to 1C and 5 are configured to be communicable wirelessly or by wire. The pole 5 is preferably separated from the sidewalk B to the extent that the pole 1A exists within the wireless communication distance of the wireless communication device provided in the notification unit 4, for example, several tens to several hundreds of meters.

  As described above, each of the poles 1 to 1C and 5 includes the first portion 1b extending in the vertical direction from the base end portion 1a and the first portion 1b extending statically or dynamically in the direction of the adjacent pole 1. 2 portion 1c.

  For example, the poles 1 to 1C and 5 are arranged in the vertical direction toward the first portion 11b extending in the vertical direction from the base end portion 11a and the adjacent pole 11 like the pole 11 shown in FIG. You may have as an 2nd part the arm 11c extended from the substantially center part to both sides, and protruding statically. Thereby, the pole 11 as a whole has a substantially cross shape.

  The poles 1 to 1C and 5 are, as the pole 12 shown in FIG. 3, a first portion 12b extending in the vertical direction from the base end portion 12a and a central portion in the vertical direction toward the adjacent pole 12. The second portion may include a portion 12c that extends obliquely upward from the second portion. As a result, the pole 12 has an overall character shape.

  Thus, since the poles 11 and 12 statically have the second portions 11c and 12c projecting in the direction of the adjacent poles 11 and 12, respectively, it is possible to alert the pedestrian. Become. Furthermore, even if the interval between the poles 11 and 12 is widened as compared with a simple cylindrical pole or the like, a pedestrian cannot pass through the space. This makes it possible to reduce the number of poles 11 and 12 installed.

  In particular, the second portion 1c may be provided with a light source such as an LED as the lighting means of the present invention, and this light source may be turned on or blinked. These lighting or blinking may be performed when a detection signal is received from the detection means 2. As a result, it is possible to more effectively alert the pedestrian.

  In the above-described embodiment, the case where the second portions 11c and 12c of the poles 11 and 12 are static and fixed has been described. However, the second portion is not limited to a static one, and the pole may have a second portion whose manner of dynamically extending changes. Thereby, compared with the case where the aspect where the poles 11 and 12 extend is static, a pedestrian can be made to recognize clearly presence of a boundary. As a result, it is possible to more effectively alert pedestrians.

  For example, as shown in FIG. 4, the pole 21 is provided with a telescopic body 21 c that can extend and contract laterally on both sides of a substantially intermediate portion of the main body 21 b that extends in the vertical direction from the base end 21 a. You may have as a part. These stretchable bodies 21c are made of a stretchable material such as rubber, and are configured to be shrinkable by an air pump (not shown) incorporated in the pole 21. When stretched, the stretchable body 21c stretches in the lateral direction so as to narrow the gap between the adjacent poles 21 as indicated by a two-dot chain line.

  In addition, the expansion-contraction body 21c expands / contracts periodically and may suppress that a pedestrian passes between the poles 21. Moreover, when it is detected from the detection means 2 that a pedestrian has approached, the stretchable body 21c may be extended to prevent the pedestrian from passing between the poles. Furthermore, when the detection means 2 detects that a pedestrian has approached, the operation cycle of the telescopic body 21c may be shortened, and the pedestrian may be prevented from passing between the poles 21. Note that only one telescopic body 21c may be provided on the pole 21. Moreover, it is also possible to psychologically suppress a pedestrian from passing between the poles 21 by the expansion and contraction of the expansion body 21c.

  Further, as shown in FIG. 5, the pole 22 may have, as the second part, arms 22c provided on both sides of the intermediate portion of the main body portion 22b extending in the vertical direction from the base end portion 22a. These arms 22c are made of a flexible material such as resin, and the arms 22c are configured to be rotatable by an electric motor (not shown) around a fulcrum of the base end portion of the arms 22c. As shown by a two-dot chain line, the arm 22c expands in the lateral direction so as to narrow a gap between the adjacent poles 22 when the arm 22c is expanded.

  Note that the arms 22c may be periodically spread to prevent a pedestrian from passing between the poles 22. Further, when the detection unit 2 detects that a pedestrian has approached, the arm 22c may spread to prevent the pedestrian from passing between the poles 22. Furthermore, when the detection means 2 detects that a pedestrian has approached, the operation cycle of the arm 22b may be shortened, and the pedestrian may be prevented from passing between the poles 22. Only one arm 22c may be provided on the pole 22. In addition, it is possible to psychologically suppress a pedestrian from passing between the poles 22 by turning the arm 22c.

  Further, as shown in FIG. 6, the pole 23 may have an inflatable body 23c as a second part at the top of the main body 23b extending in the vertical direction from the base end 23a. The inflatable body 23c is made of a flexible material such as resin, and is configured to be inflatable by an air pump (not shown) incorporated in the main body 23b. As shown by a two-dot chain line, the expansion body 23c expands in a substantially spherical shape, and narrows a gap between other adjacent poles 23.

  In addition, the expansion body 23c may be periodically expanded and contracted to suppress a pedestrian from passing between the poles 23. Moreover, when the detection means 2 detects that a pedestrian approaches, the expansion body 23c may expand | swell and may prevent a pedestrian from passing between the poles 23. FIG. Furthermore, when the detection unit 2 detects that a pedestrian has approached, the operation cycle of expansion and contraction of the expansion body 23c may be shortened, and the pedestrian may be prevented from passing between the poles 23. Moreover, it is also possible to psychologically suppress a pedestrian from passing between the poles 23 due to the expansion of the expansion body 23c.

  In addition, in these poles 21-23, the light sources which consist of LED etc. are provided in the 2nd parts 21c-23c especially, and this light source may turn on or blink. You may perform these lighting or blinking, when the detection means 2 detects that the pedestrian approached. As a result, it is possible to effectively call attention to the pedestrian.

  Further, for example, in order to prevent one or a plurality of poles from passing through the pedestrian, a height at which the pedestrian passes, for example, a portion located at a position of about several tens of centimeters to 1 mm above the second portion You may have as.

  Specifically, as shown in FIG. 7, the pole 24 may have a bellows body 24c, which is also the main body portion 24b, as the second portion with respect to the base end portion 24a. The bellows body 24c is made of a flexible material such as resin, and is configured to be stretchable by an air pump (not shown) built in the base end portion 24a. The bellows body 24c extends as indicated by a two-dot chain line and suppresses a pedestrian from passing over the pole 24.

  The pole 24 may prevent the pedestrian from passing over the pole 24 by periodically expanding and contracting the bellows body 24c. Moreover, when the detection means 2 detects that a pedestrian has approached, the bellows body 24c may be expanded to prevent the pedestrian from passing over the pole 24. Furthermore, when the detection means 2 detects that a pedestrian has approached, the operation cycle of expansion and contraction of the bellows body 24c may be shortened, and the pedestrian may be prevented from passing over the pole 24. It is also possible to psychologically suppress the pedestrian from passing over the pole 24 due to the expansion of the bellows body 24c.

  Further, as shown in FIG. 8, the pole 25 may have an expansion body 25c that is also a main body portion 25b as a second portion with respect to the base portion 25a. The inflatable body 25c is made of a flexible material such as resin, and is configured to be inflatable by an air pump (not shown) incorporated in the base portion 25a. As shown by a two-dot chain line, the expansion body 25c expands upward, and suppresses a pedestrian from passing over the pole 25.

  The inflatable body 25c may be periodically expanded and contracted to suppress a pedestrian from passing over the pole 25. Moreover, when the detection means 2 detects that a pedestrian has approached, the expansion body 25c may be expanded to prevent the pedestrian from passing over the pole 25. Furthermore, when the detection unit 2 detects that a pedestrian has approached, the operation cycle of expansion and contraction of the expansion body 25c may be shortened, and the pedestrian may be prevented from passing over the pole 25. Moreover, it is also possible to psychologically suppress a pedestrian from passing over the pole 25 by the expansion of the expansion body 25c.

  Moreover, as shown in FIG. 9, the pole 26 may be provided with a bar 26c that can move up and down on a main body portion 26b that is installed on each of a plurality of base end portions 26a and extends in an extending direction. The bar 26c is made of a flexible material such as resin, and is configured to be movable up and down by an air pump, an actuator, etc. (not shown) built in the main body 26b. When the bar 26c is positioned upward as indicated by a two-dot chain line, the pedestrian is prevented from passing between the main body portions 26b.

  The bar 26c may periodically move up and down to prevent the pedestrian from passing between the main body portions 26b. Moreover, when the detection means 2 detects that the pedestrian has approached, the bar 26c may move upward to prevent the pedestrian from passing between the main body portions 26b. Furthermore, when the detection unit 2 detects that a pedestrian has approached, the operation cycle of the vertical movement of the bar 26c may be shortened, and the pedestrian may be prevented from passing between the main body portions 26b. Moreover, it is also possible to psychologically suppress a pedestrian from passing between the main body portions 26b by the vertical movement of the bar 26c.

It may blink. You may perform these lighting or blinking, when the detection means 2 detects that the pedestrian approached. As a result, it is possible to effectively call attention to the pedestrian.

  In the above-described embodiment, the case where the notification unit 4 is provided in the pole 5 has been described. However, a notification means may be provided in things other than the pole.

  Specifically, as shown in FIG. 10, a notification unit 4 </ b> A may be provided on the upstream side of the roadway A adjacent to the sidewalk B. This notification means 4A is made of an obstacle with a height of several centimeters embedded in the roadway A. In the figure, the notification means 4A is two rows, but may be one row or three or more rows. In addition, it is preferable that 4 A of alerting | reporting means are several tens to hundreds of meters away from the sidewalk B.

  When the pedestrian is not close to the pole 1A, the notification unit 4A is embedded in the roadway A, and the driver who drives the vehicle passing through the roadway A does not notice the presence of the notification unit 4A, or I don't really care.

  On the other hand, when the pedestrian is close to the pole 1A, the notification means 4A is in a state of protruding from the roadway A, and the driver who drives the vehicle passing this roadway A gets over the notification means 4A. , Notice its existence. Accordingly, it is possible to notify the driver of the vehicle traveling on the roadway A upstream of the pole 1 that there is a pedestrian close to the boundary of the sidewalk B partitioned by the plurality of poles 1. It is possible to call attention to.

  Furthermore, although not shown in the figure, an informing means 4B made of a light emitting plate embedded in the road A may be provided on the upstream side of the road A adjacent to the sidewalk B. The notification means 4B is separated from the sidewalk B to the extent that at least one pole 1, 1A exists within the wireless communication distance of the wireless communication device provided in the notification means 4B, for example, several tens to several hundreds of meters. Is preferred.

  When the pedestrian is not close to the pole 1A, the notification unit 4B does not emit light, and the driver who drives the vehicle passing through the roadway A does not notice or hardly notices the presence of the notification unit 4B. .

  On the other hand, when the pedestrian is close to the pole 1A, the notification unit 4B emits light, and the driver who drives the vehicle passing through the roadway A notices the notification unit 4B. Thereby, it is possible to notify the driver of the vehicle traveling on the road A that is separated upstream from the pole 1 that there is a pedestrian close to the boundary of the sidewalk B partitioned by the plurality of poles 1, It is possible to alert the driver.

  Note that the notification unit 4B may, for example, fill light emitting plates of a plurality of colors, such as red and yellow, and increase the warning as it goes from the upstream side to the downstream side. Further, the warning interval may be strengthened by shortening the light emission interval of the notification unit 4B from the upstream side toward the downstream side.

  Furthermore, as shown in FIG. 11, a notification unit 4 </ b> C may be provided that includes a projector that projects information for alerting on the roadway A upstream of the roadway A adjacent to the sidewalk B. In addition, it is preferable that the notification means 4C is separated from the sidewalk B to the same extent as the notification means 4B.

  When the pedestrian is not close to the pole 1A, the notification unit 4C does not perform any projection, and the driver who drives the vehicle passing through the roadway A is not concerned at all.

  On the other hand, when the pedestrian is close to the pole 1A, the notification unit 4C projects the caution information on the road A, and the driver who drives the vehicle passing the road A notices the caution information. Accordingly, it is possible to notify the driver of the vehicle traveling on the roadway A upstream of the pole 1 that there is a pedestrian close to the boundary of the sidewalk B partitioned by the plurality of poles 1. It is possible to call attention to.

  Note that the information for calling attention may be, for example, character information such as “forward caution”, “forward pedestrian pop-out caution”, “deceleration”, or display of figures, symbols, and the like.

  Instead of the notification means 4C from the projector, a signboard made up of an LED or the like that displays information for calling attention may be used.

  In the above-described embodiment, the case where the region corresponding to one region of the present invention is the sidewalk B and the region corresponding to another region of the present invention is the roadway A has been described. However, one area or another area of the present invention is not limited to these areas.

  For example, one area may be a facility site, a park, or the like, and another area may be a cliff, an opening, a bicycle path, or the like. Furthermore, the portion B2 may be a crossing designation region other than the pedestrian crossing.

  In the above-described embodiment, the detection unit 2 has been described as detecting the proximity of a pedestrian. However, the detection means 2 is not limited to this as long as it detects an environmental change in one region or another region. For example, the detection unit 2 may detect that a traffic participant such as a bicycle passing the sidewalk B comes close.

  Moreover, the detection means 2 may detect that traffic participants, such as a car and a motorcycle passing along the road A, approach. In this case, it is possible to alert a traffic participant such as a pedestrian who walks on the sidewalk B that the traffic participant may row the pole 1 and invade the sidewalk B, so as to call attention.

  Furthermore, the detection means 2 may detect that a traffic participant such as a pedestrian crosses between the poles 1. In this case, it is preferable that the alarm means 4, 4 </ b> A, 4 </ b> B issue a warning with a high degree of urgency that is different from the case where a traffic participant such as a pedestrian approaches the pole 1.

  Further, the detection means 2 may detect other changes in the environment such as the roadway A and the sidewalk B, for example, it has become dark due to dusk, rain, snow, or the like.

According to the sign of the present invention, the sign placed on at least a part of the boundary that divides one area where the traffic participant passes and the other area can extend and contract laterally with respect to the main body. The expansion / contraction mode of the expansion / contraction part changes automatically and intermittently . For this reason, compared with the case where a sign does not have such an expansion-contraction part , a traffic participant can be made to recognize the presence of the said boundary clearly. As a result, it is possible to call attention to traffic participants so as to suppress intrusion from one area to another area.

The sign of the present invention preferably has a communication function, and when a predetermined signal is received using the communication function, the expansion / contraction mode of the expansion / contraction part is preferably changed.

In this case, when a predetermined signal is received, the expansion / contraction mode of the expansion / contraction part changes, so the traffic participant is effectively alerted to prevent entry into other areas from the side of the sign. It becomes possible to do.

The method of using a sign according to the present invention is a method of using a sign installed at least at a part of a boundary that partitions one area through which a traffic participant passes and another area, and the sign is located at the boundary. A main body extending in a vertical direction from a base end portion to be installed; and an expansion / contraction portion that can expand and contract laterally with respect to the main body, and the expansion / contraction mode of the expansion / contraction portion is automatic and intermittent It is characterized by changing to.

A first alerting system of the present invention is an alerting system including a plurality of signs arranged in parallel at least at a part of a boundary partitioning one area where a traffic participant passes and another area. , each said label, possess a body portion that extends vertically from the base end portion which is disposed to each of the boundary, and automatically extendable telescopic part toward the side relative to the body portion The expansion / contraction mode of the expansion / contraction part changes automatically and intermittently .

And since the expansion and contraction aspect of the expansion and contraction part that can expand and contract toward the side with respect to the main body part automatically and intermittently changes , the sign does not have such an expansion and contraction part , It is possible to make traffic participants clearly recognize the existence of the boundary. As a result, it is possible to effectively alert traffic participants so as to suppress intrusion into other areas as compared with the case where the sign does not have such a stretchable part. .

In the first alerting system of the present invention, a detecting unit that detects an environmental change in the one region or the other region is provided, and when the detecting unit detects an environmental change, the expansion / contraction mode of the expansion / contraction part changes. It is preferable to do.

Further, in the first alert system of the present invention, it is provided with detecting means for detecting an environmental change in the one area or the other area, and when the detecting means detects an environmental change, the expansion / contraction mode of the expansion / contraction part It is also preferable to change the period of the change.

A second alerting system of the present invention is an alerting system comprising a plurality of signs arranged in parallel at least at a part of a boundary partitioning one area where a traffic participant passes and another area. , each said label, possess a body portion that extends vertically from the base end portion which is disposed to each of the boundary, and a stretchable elastic portion toward the label adjacent to the main body portion, The expansion / contraction mode of the expansion / contraction part changes automatically and intermittently .

And since the expansion / contraction aspect of the expansion-contraction part which can be expanded-contracted toward the label | marker adjacent to each main body part installed in a boundary changes automatically and intermittently , a sign has such an expansion-contraction part . Compared with the case where there is not, it can make a traffic participant recognize clearly the existence of the said boundary. As a result, it is possible to effectively alert the traffic participants so as to suppress intrusion into other areas.

A pole (sign) 1 and a warning system 10 according to a reference embodiment of the present invention will be described with reference to the drawings.

In the embodiment of the present invention, for example, as shown in FIG. 4, the pole 21 can be expanded and contracted laterally on both side portions of a substantially intermediate portion of the main body portion 21 b extending in the vertical direction from the base end portion 21 a. You may have the expansion-contraction body 21c as a 2nd part. These stretchable bodies 21c are made of a stretchable material such as rubber, and are configured to be shrinkable by an air pump (not shown) incorporated in the pole 21. When stretched, the stretchable body 21c stretches in the lateral direction so as to narrow the gap between the adjacent poles 21 as indicated by a two-dot chain line.

In addition, the expansion-contraction body 21c expands / contracts periodically and may suppress that a pedestrian passes between the poles 21. Moreover, when the detection means 2 detects that a pedestrian has approached, the elastic body 21c may be extended to prevent the pedestrian from passing between the poles. Furthermore, when the detection means 2 detects that a pedestrian has approached, the operation cycle of the telescopic body 21c may be shortened, and the pedestrian may be prevented from passing between the poles 21. Note that only one telescopic body 21c may be provided on the pole 21. Moreover, it is also possible to psychologically suppress a pedestrian from passing between the poles 21 by the expansion and contraction of the expansion body 21c.

Further, in the reference embodiment of the present invention, as shown in FIG. 5, the pole 22 has arms 22c provided on both sides of the middle portion of the main body portion 22b extending in the vertical direction from the base end portion 22a as the second portion. You may do it. These arms 22c are made of a flexible material such as resin, and the arms 22c are configured to be rotatable by an electric motor (not shown) around a fulcrum of the base end portion of the arms 22c. As shown by a two-dot chain line, the arm 22c expands in the lateral direction so as to narrow a gap with another adjacent pole 22 when the arm 22c is expanded.
