JP 2010-168897 A JP 2000-136513 A JP-A-6-108425 JP 2009-275424 A JP-A-10-311209 JP-A-9-88019 JP-A-2005-42344 Japanese Patent No. 5072783

  Among the above-mentioned patent documents 1 and 2, the road sign pillar described in the above-mentioned patent document 1 has ribs on the peripheral wall, so that the peripheral wall surface protrudes to the outside, which impairs aesthetics and is difficult to design. Contaminants easily adhere to the surface and are difficult to clean. In addition, the road sign pillar described in Patent Document 2 is replaced with an expensive elastic resin such as polyurethane, and the resilience of a sign pillar body made of a synthetic resin that is inferior in flexibility and resilience and a highly resilient elastic body. Two types of members with different properties are required, and two types of molds are required, which increases costs, and a combination of two different material properties creates a singularity. However, there is a possibility that a large stress is generated only at a specific part in terms of strength.

In addition, since the self-luminous delineator described in Patent Document 4 uses a transparent pipe, the pipe material is limited to a transparent one, and the degree of freedom in material selection is limited. The parts must be arranged separately.

  Furthermore, among the above-mentioned Patent Documents 5 to 8, the synchronization system described in Patent Documents 5 to 7 requires an operation each time when it is activated by a switch, and does not start if it is forgotten. If the indicator breaks down, it will not be able to flash synchronously with other devices. The synchronization system of Patent Document 8 is also a type in which an operation switch is inserted, and further, due to the mechanism, there is a possibility that the synchronization relationship may be lost if one is broken.

As described above, all of the devices described in the above patent documents have problems. For example, the self-luminous road marking body described in Patent Documents 3 and 4 cannot insert a large member such as a circuit board or a control box into the pole hole.
Therefore, in order to solve this problem, the present inventor, in order to accommodate a large circuit board and a box containing the board in the pole, the space in the pole hole by changing the pole from a cylindrical shape to a flat rectangular shape. On the other hand, when a square shape is used, stress concentrates at the corners, making it difficult to bend, and if it is bent greatly, a new problem that may break from the corners appears. The present invention has been completed by studying from a wide angle, such as solving the problem by providing stress reducing means at the corners, and solving the problems that have appeared.

With this configuration, the hollow bore 21 ₀ of the hollow cylindrical body, since the cross-sectional shape perpendicular to the longitudinal direction is substantially rectangular to substantially elliptical shape, the efficiency of space inside the hollow hole, as compared to prior art cylindrical pole It can be used effectively and can be equipped with a light emitter control box 30 to be described later. Also, a pair of window holes 26a, which will be described later, are provided in the pair of opposed plate walls 21a and 21b. Since these opposed plate walls are wider than the side plate walls, a light emitter is formed on the top of a conventional cylindrical pole. The light emitting area is larger than that provided. That is, it is arranged at intervals a plurality of emitters 32 ₁ in cascade in the longitudinal along the window hole 26a in the longitudinal direction, the light emitting area is increased. In addition, the width length of each opposing board wall 21a, 21b is 92 mm, for example, and the width length of each side board wall 21c, 21d is 60 mm, for example.

  The opposing side plate walls 21c and 21d are each curved in an arc shape to the outside, and predetermined corners 21ac, 21cb, 21bd, and 21da are provided with a predetermined R (R). Thereby, even if a vehicle etc. contact, it can prevent that a vehicle etc. are damaged.

  The hollow prism body 21 is made of a thermoplastic elastomer. This thermoplastic elastomer (TPE) is, for example, polyester TPE, polyurethane TPE, polyolefin TPE, polystyrene TPE, polyamide TPE, ionomer TPE, diene TPE, polyvinyl chloride TPE, polyvinyl chloride / polyurethane. Polymer alloy TPE, a mixture of thermoplastic resin and rubber, and the like. Of these thermoplastic elastomers, thermoplastic polyurethanes and soft polyolefins are preferred in view of ease of molding, resilience against durability or contact with vehicles, durability, and the like. In addition, a color prismatic body can be produced by using a material mixed with a coloring material. The color of the coloring material is, for example, green. This hollow prismatic body 21 is formed by injection molding. Furthermore, it is preferable to form a coating layer on which a synthetic resin paint that expresses self-cleaning properties is applied on the surface of the molded body. Thereby, contamination of the surface of the hollow prismatic body can be suppressed.

As shown in FIG. 1, the hollow prismatic body 21 has a base pillar portion 21A fixed to the pedestal 10 and reflectors 41a and 41b (see FIG. 2) extended from the base pillar portion by a predetermined length. Is divided into an intermediate column portion 21B to which the is attached and an upper column portion 21C extended from the intermediate column portion by a predetermined length. These sections are divided for ease of explanation, and there is no such mark on the actual hollow prismatic body. The division of the intermediate column portion is not essential, and the length of the base column portion 21A is, for example, 200 mm, the length of the intermediate column portion 21B is 150 mm, and the length of the upper column portion 21C is 190 mm. Further, H ₃ in FIG. 1 is 300 mm, H ₄ is 190 mm, and H ₅ is 60 mm.

  Among these sections, as shown in FIG. 2, the base column portion 21A has bolt insertion holes 23a and 23b formed in the vicinity of the root end portion.

Further, four corners 21ac, 21cb, 21bd, 21da are the four corners of the hollow hole 21 in _0, Sumikabe that this portion chamfered wall thickness (hereinafter also referred to as thick angle walls. ) 22ac, 22cb, 22bd, 22da are formed (see FIG. 4B). These thick square walls 22ac to 22da have a width and length d ₁ shown in FIG. 4B, a height of the inclined surface d ₂ , and a thick square wall thickness t ₁ , for example, d ₁ is 8.8 mm, d ₂ is 3mm, _{t 1} is 4.0mm. From these dimensions, each of the thick square walls 22ac to 22da is increased by 1.0 mm as compared with the opposing plate wall or the side plate wall (3.0 mm), and the thickness becomes 4.0 mm (t ₁ ). Since the base pillar portion 21A is formed with thick corners, the base pillar portion is less likely to bend than the other portions, while the self-restoring force is reinforced.

Further, as shown in FIG. 4A, the thick square walls 22ac, 22cb, 22bd, and 22da of the four corners 21ac, 21cb, 21bd, and 21da have long holes 24a, 24b, and 24c having predetermined lengths. , 24d are formed. The two long holes 24b and 24c are not shown in FIG. 2 and FIG. 4, but each thick wall of the corner of the opposing plate wall 21b is opposed to the thick square wall 22ac and 22da of the corner of the opposing plate wall 21a. 22cb and 22bd are hidden by the opposing plate wall 21a. These long holes 24b and 24c have the same shape. These long holes 24a, 24b, 24c, 24d are holes having a rectangular opening having a narrow width and a long length, and penetrate through the respective thick square walls 22ac, 22cb, 22bd, 22da. These long holes are formed from the lowermost end of the base column portion 21A to a predetermined length, for example, 50 mm away from the location toward the intermediate column portion 21B. By these long holes 24a to 4d, the stress from the outside is reduced, but it becomes easy to bend, and breakage or buckling from the base column part 21A can be prevented. That is, these long holes 24a to 24d can reduce the maximum stress applied to the corners, and can be easily bent to prevent breakage or buckling from the root portion. These long holes serve as stress-reducing bends.
The long holes 24a to 24d have a long hole width of, for example, 2.0 mm and a long hole length of, for example, 100 mm or 150 mm. A long hole is easily bent when its length is long, but its self-restoring force is weakened. However, this reduction in self-restoring force is reinforced by making the corners thick walls.

Further, as shown in FIG. 5, it is preferable that the long hole is given a predetermined R to the corners 24 ₁ , 24 ₂ , 24 ₃ , 24 ₄ in the hole. FIG. 5 is a VA portion of FIG. 4, and reference numerals 24 ₃ and 24 ₄ are omitted in FIG. 5A. R is R1 (radius 1.0 mm), R2 (radius 2.0 mm), and R4 (radius 4.0 mm) (see FIGS. 5B to 5D). The maximum of R can be up to radius R10. By attaching such R, the stress applied to the long hole portion can be relaxed. In particular, if the length of the long hole is shortened, the stress at the root portion increases, and the stress concentrates on the long hole portion, so that R serves as an effective countermeasure. This stress relaxation will be described later.

In this embodiment, each of the long holes 24a to 24d is formed in each thick square wall 22ac to 22da. However, the long holes 24a to 24d are formed on the wide opposing plate walls 21a and 21b along the thick square walls. Also good. That is, the long holes 24a to 24d are formed in the respective thick square walls 22ac to 22da or the pair of opposing plate walls 21a and 21b. In addition, it is said that the place which formed the long hole including these places was provided in the corner | angular part. Further, in this embodiment, the corner portion of the base column portion 21A is made a thick square wall to reinforce the restoring force. However, if a desired self-restoring force is obtained at the corner portion, it is not always necessary to make it thick. Absent. Furthermore, although the long hole penetrated the thick square wall, it may be formed by a groove having a predetermined length and depth without penetrating the thick hole. The length of the groove is substantially the same as that of the long hole, and the shape thereof is a dent, U shape, or V shape.
If a groove is used instead of the long hole, the following effects are obtained. That is, since the light emitter control box 30 is mounted on the upper column portion 21C, the upper portion may become heavy. If the upper part is heavy in this manner, the vehicle body or the like will contact or collide and a strong stress will be applied, but the column will bend, but depending on the excessive stress, it may not be restored by bending or bending. However, if the groove is used, the restoring force is increased from that of the long hole, and the above-described disadvantage is avoided. Since the long holes and grooves impart desired bending and restoring force, these long holes and grooves are not limited to the above-mentioned ones, and other known means that exhibit other similar actions, For example, a plurality of holes may be used.

  As shown in FIGS. 1 and 2, the intermediate column portion 21B has reflectors 41a and 41b mounted at predetermined intervals at two locations on the outer periphery thereof. These reflectors are retroreflectors or electroluminescence (EL).

Upper pillar portion 21C, as shown in FIG. 2, a pair of opposing plate walls 21a, respectively 21b window hole 26a, 26b are formed, In addition, the light-emitting element control box 30 is inserted into the hollow hole 21 inside _0.

First, a pair of window holes 26a, 26b are opposed wide opposite plate walls 21a, to 21b, it is formed in communication with the hollow hole 21 ₀ through these opposing plate walls. Although one window hole 26b is not shown in FIGS. 1, 2, and 4, it is formed in the opposing plate wall 21b opposite to the opposing plate wall 21a and is hidden by the opposing plate wall 21a. These window holes 26a and 26b have the same shape. One window hole 26a, as shown in FIG. 2, a frame-shaped window frame 26 ₁ rectangular provided in the longitudinal direction of the opposite plate walls 21a, made of a rectangular opening 26 ₂ which provided in the window frame , the opening 26 ₂ is communicated to the interior of the hollow hole 21 _0. Since the opening 26 ₂ is turned rectangle can arranged a plurality of light emitters in a column, you can enlarge the light emitting area. Further, window holes 26a, as shown in FIG. 1, as shown in FIG. 2, a frame-like window frame 26 ₁ is recessed a predetermined depth from the outer peripheral wall surface, the opening 26 ₂ is formed on the bottom of this depth. From the window hole 26a, the light from the light emitter is projected to the outside. In this case a plurality of light emitting element 32 ₁ is housed in the light emitter control box 30, since the portion recessed from the outer peripheral wall surface, there is no possibility that such vehicle strikes directly directly emitters are protected (FIG. 2, FIG. 6).

Also included are curved outwards.

  With reference to FIG. 1 to FIG. 4 and FIG. 6, assembly of the line-of-sight guide, installation on the road surface, and evaluation of flexibility will be described.

In assembling the line-of-sight guide 1, first, the luminous body control box 30 is assembled by the method described above. Illuminant control box 30 assembled into the hollow hole 21 ₀ of the hollow prismatic body 21, and fixed to complete the assembly of the visual guidance pillar 20 by mounting the pole cap 40 with intervening reflector 41c on top. In addition, reflectors 41a and 41b are mounted in advance on the intermediate column portion 21B of the hollow rectangular column 21.

As shown in FIGS. 2 and 3, the line-of-sight guide 1 is first installed in a state where a hole larger than the anchor 17 is dug in the road surface 2, an adhesive is poured into the hole, and the base bottom surface is in contact with the road surface. The anchor 17 is embedded at At this time, since the upper surface of the anchor protrudes from the road surface 2, the anchor fixing adhesive does not flow into the anchor, and the hollow prismatic body or the pedestal is destroyed by collision with the hollow prismatic body 21 and the like. Even during replacement, the anchor can be used as it is, making replacement easier. The pedestal 10 is fixed to the anchor 17. This fixing is performed by screwing the bolt 16 into the insertion hole 14 of the base 10. Next, the line-of-sight guide column 20 is fixed to the base 10. The fixing is performed by inserting bolts 18 into the through-hole 13 ₀ of the base 10.

  These line-of-sight guides A to D (FIG. 9) installed on the road are bent due to contact or collision of a vehicle or the like with a strong stress. In preparation for such a case, the following flexibility was evaluated.

The line-of-sight guide 1 was produced with the following dimensions and materials, and the flexibility was evaluated.
(Size)
The height H 1 of the line-of-sight guide ₁ is 650 mm, the height H ₂ of the pedestal 10 is 50 mm, the width W ₁ is 150 mm, the horizontal widths of the opposing plate walls 21a and 21b of the hollow prism 21 are 92 mm, and the width of the side plate wall is The thickness of the opposing plate wall of 60mm, 21A, 21B is 3mm, the thickness of the side plate wall is 3mm, the thickness of the thick square wall is 4mm, the height from the bottom end to the top is 560mm, and the bottom end to the window hole 26a The height is 386 mm, the length of the long hole is 100 mm, the material of the hollow prismatic body 21 is polyurethane, and R at the upper and lower ends in the hole is R0 (radius 0 mm), R1 (radius 1.0 mm), R4 (radius 4. 0 mm).
(Evaluation method)
A load was applied to the line-of-sight guide 1 from the direction of the arrow in FIG. 7, and the stress distribution applied to the root column 21A was evaluated.
(Evaluation results)
As a result, as shown in FIG. 8, when the maximum principal stress applied to the portion near the root end of the base column portion 21A is L1, and the maximum principal stress applied to the lower end bending portion in the hole is L2, the portion close to the root end It has been found that the maximum principal stress L1 changes depending on the size of R provided in the hole, that is, R0 is the largest and decreases according to R1, R2 and R4. On the other hand, the maximum principal stress L2 is substantially the same for R0, R1 and R2, and slightly decreased for R4. In addition, when an experiment was conducted with a long hole of 150 mm, the maximum principal stress L1 was smaller than 100 mm, and L2 was also smaller than 100 mm.
From the above, it was verified that when the length of the long hole was set to 100 mm, the stress relaxation effect was exhibited when R was provided at both the upper and lower ends in the hole.

The synchronous flashing system will be described with reference to FIGS. 9 is an external view of a state in which a plurality of line-of-sight guidance signs are installed on the center line, FIG. 10 is a block diagram of a synchronous flashing circuit for synchronous flashing, and FIG. 11 is a flowchart of a sunset detection unit of the synchronous flashing circuit. 12 is a schematic diagram at the time of synchronous communication, FIG. 13 is a timing chart at the time of synchronous communication, FIG. 14 is a flowchart of the synchronous communication unit of the synchronous flashing circuit, and FIG. is there.
The synchronous blinking system includes a plurality of, for example, four line-of-sight guide marks A to D, and the IDs of the same group are set in advance for these line-of-sight guide marks. These IDs are set in the respective synchronous blinking circuits 32A of the line-of-sight guidance signs A to D. As a result, the line-of-sight guide having the same group ID can transmit and receive data for synchronization.
As shown in FIG. 9, the four line-of-sight guidance marks A to D are installed on the road surface or the like at a predetermined interval. The line-of-sight guides A to D are arranged such that the window holes 26a and 26b of the line-of-sight guides A to D follow the line on the center line 2 of the road surface 1, that is, the pair of opposing plate walls 21a and 21b are line 2 It installs with the said installation method in the direction which follows the line 2 at each side board wall 21c and 21d. This installation, each window hole 26a of the delineator to D, 26b are along a line, since the light ₁ LED 32 from these windows hole is issued, the visibility of the vehicle driver is up.

Synchronous blinking of these line-of-sight guidance marks A to D is performed by a synchronous blinking circuit 32A attached to each line-of-sight guidance mark.
Synchronous flasher circuit 32A, as shown in FIG. 10, the storage battery 32a for storing electric power that is electromotive by solar panel 35, a plurality of LED 32 ₁ to be lit by the power from the storage battery, solar panels 35 A sunset detector 32b that determines the darkness of the surroundings based on a change in voltage generated at the time of transmission, and data for synchronization is transmitted to or output from another gaze guidance mark by the output of the sunset detection section. a wireless communication unit 32g that receives, LED 32 ₁ other delineators illuminant (LED) and the synchronization timer 32e to be turned in synchronism, the control unit that controls the wireless communication unit 32g and the synchronization timer 32e 32c and a storage portion 32d which stores a predetermined program, and controls the power from the storage battery 32a LED 32 _1, the power supply supplies power to such a wireless communication unit 32g, and a control unit 32c And it includes a control unit 32f. The storage unit 32d stores a predetermined program, for example, the program shown in FIGS.

  Each of the four line-of-sight guides A to D includes a synchronous blinking circuit 32A (see FIG. 10), and any of the line-of-sight guides, for example, the line-of-sight guides A detects darkness, that is, sunset. . This sunset detection is detected by the sunset detector 32b of the synchronous blinking circuit 32A. As shown in FIG. 11, the sunset detector 32b starts darkness detection and detects the amount of charge current from the solar panel 35 and the confirmation of this electromotive force over a predetermined time (for example, 10 seconds). From these detected values, it is detected whether the charging current amount is 2 mA or less and the electromotive force is 1.2 V or less, for example. If this condition is satisfied, plus 1 (+1) is added to the operation management variable. Then, in the next step, it is determined whether this motion management variable is 2 or larger (variable> = 2?), And if this condition is satisfied, it is determined that the sunset has occurred and the darkness detection is terminated. When the charging current amount and the electromotive force do not reach the predetermined values, the operation management variable is set to minus 1 (−1) to return the flow, and the operation management variable may not satisfy the above condition. Restore the flow and try again to detect the darkness.

When the line-of-sight guide A detects sunset, the wireless communication unit 32g (wireless module mounted on the board) of the synchronous blinking circuit 32A is activated, and synchronization data is transmitted to other line-of-sight guides (for example, at intervals of 100 msec. Send continuously). After this data transmission, the synchronization timer 32e is started. Thereafter, the line-of-sight guide A enters the reception mode, and during this time, for example, the reception operation is repeated for 90 msec reception state, for example, 150 msec sleep state, and waits (see FIG. 13). The intermittent reception operation time is about 18 minutes, and the count end time of the synchronization timer is about 19 minutes later.
When another gaze guidance mark, for example, the gaze guidance mark B detects sunset, while waiting for the gaze guidance mark A, this gaze guidance mark B also transmits data in the same manner as the gaze guidance mark A, and is used for synchronization after this data transmission. Start the timer. Then, the line-of-sight guide A that has been activated first receives the data of the line-of-sight guide B, resets the synchronization timer, and restarts (see FIG. 12).

  The line-of-sight guide A determines the number of times the synchronization data is received after the synchronization timer count ends (about 19 minutes have elapsed), and determines whether it is a parent device or a child device based on this number of times. For example, when the synchronization data reception count is 0, it is determined as a parent device, and when the reception count is other than 0, it is determined as a slave device. Since a slight time lag occurs between the master unit and the slave unit, synchronous communication is performed only once at the end to correct this. Further, since the line-of-sight guidance mark A becomes a slave unit, it is in a reception state for a predetermined time (for example, 8 seconds) (see FIG. 12). Then, the line-of-sight guide A waits (for example, 10 seconds) until the synchronization timer set time elapses and starts synchronous flashing.

  On the other hand, the line-of-sight guidance mark B waits until the synchronization timer set time elapses. Similarly, since the line-of-sight guidance mark B serves as a master unit, the synchronization data is transmitted only once after 5 seconds from the determination. Then, it waits (for example, 10 seconds) until the synchronization timer set time elapses and starts synchronous flashing.

The blinking of the LED is activated after the end of synchronous communication. That is, as shown in FIG. 15, LED 32 ₁ is a predetermined time, for example, off for 1 second, repeated blinks continuously a predetermined time, for example 55 milliseconds lighting. By these blinking, a predetermined time, for example, 1 minute has passed, and the amount of charging current and the electromotive force from the solar panel 35 are confirmed. The amount of charging current is, for example, 2 mA or more, and the electromotive force is, for example, 1.2 V or more. When detected, the blinking of the LED ends.

  According to this synchronous flashing system, the line-of-sight guide signs constituting the group can be flashed synchronously by using the timers for synchronization and setting the respective set times for them. In addition, even if some of these line-of-sight guides do not start due to a failure or the like, the other line-of-sight guides can be blinked synchronously.

  Note that this synchronous flashing system is not limited to the above-described synchronous flashing circuit, but other systems using other known synchronous flashing circuits, for example, a so-called system that takes a timing by receiving radio waves sent from GPS. GPS synchronization system, a system that outputs a reference radio wave from the master unit, and a plurality of slave units that are received by a built-in receiver to take timing. A so-called parent-slave synchronization system, a blinking control signal transmitted from the master device guides each line of sight A so-called master method in which blinking operation is performed by selectively receiving each mark, and a system using standard radio waves, address setting, and a method for correcting light emission synchronization may be employed.

According to the line-of-sight guidance mark of the first embodiment, the visibility to the driver can be enhanced by turning on and blinking the light emitter in a situation where visibility is poor such as at night. In addition, even when a vehicle or the like comes into contact or collides and a strong impact force is applied, the stress applied to the base column part is reduced by the stress reducing bend applying part, and it bends easily. Can be prevented. In addition, after the stress is released, the corners become bone struts and self-restoring force works, so that they can be restored quickly. In addition, even if an excessive impact force is applied to the gaze guidance mark and it is damaged, the luminous body control box and the internal parts are covered with the transparent case and the case cover, so that the parts can be prevented from being damaged or scattered. Furthermore, since the pedestal and the line-of-sight guide column are fixed by a replaceable fixing means, the damaged member can be easily replaced when the pedestal or the line-of-sight guide column is damaged, making it economical and easy to maintain and maintain. Become.
In addition, according to this system for synchronously flashing the visual guidance indicator, the visual guidance indicators constituting the group can be synchronously flashed by using the synchronization timers and setting the respective set times for them. In addition, even if some of these line-of-sight guides do not start due to a failure or the like, the other line-of-sight guides can be blinked synchronously.
