Description

[Technical field]

[0001] The present invention relates to a position indicator. [Background technology]

[0002] Conventionally, temporary position indicators that are installed on roads to indicate vehicle stopping positions and no-entry positions are generally constructed by bridging a pair of road cones with a cone bar. In addition, some of the cone bars are equipped with light-emitting parts to improve visibility.

[0003] On the other hand, Patent Document 1 discloses a display device for expressway construction, which includes a rod-shaped member placed on the road surface between the construction area where construction vehicles move and the area where a guide stands, with light-emitting devices on both ends of the rod-shaped member and a flag in the center. The display device is directly installed on the road surface, eliminating the need for road cones and improving portability. When the display device is used in expressway construction, if a construction vehicle is backing up and trying to enter the area where a guide stands, the light emitted by the rod-shaped member, flag, and light-emitting device can be visually recognized to prevent the construction vehicle from approaching the guide. Even if the crew of the construction vehicle does not notice the rod-shaped member, the crew of the construction vehicle can notice the rod-shaped member by the rear wheels of the construction vehicle coming into contact with the rod-shaped member.

[0004] [Patent Document 1] Utility Model Registration No. 3228468 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the configuration disclosed in Patent Document 1, the light emitting device and the flag are provided protruding from the rod-shaped member so as to stand up when installed on the road surface, so there is a risk of the device tipping over during use due to the influence of strong winds or the inclination of the road surface on which it is installed. If the device tips over, visibility may be significantly reduced and the light emitting device may be damaged. Furthermore, if a vehicle comes into contact with the display device, it may collide with the light emitting device and the flag protruding from the rod-shaped member and damage them.

[0006] In addition, the display device disclosed in Patent Document 1 is intended for construction work on expressways, but can also be used to divide areas for vehicles and people on public roads, in factory sites, etc. However, the display device has the same problems when used on public roads and in factory sites. Furthermore, the display device is not limited to dividing areas for vehicles and people, and can be installed along boundary positions when dividing the ground into specified areas for other purposes, but the same problems also occur in this case.

[0007] The present invention has been made in view of the above background, and aims to provide a position indicator that is highly portable, has improved visibility, and is prevented from being damaged. [Means for solving the problem]

[0008] One aspect of the present invention is A position display device (1) that is placed on the ground and displays the boundary positions of a partitioned area, A rod-shaped main body portion (10) having a side surface extending in the longitudinal direction; a light emitting portion (20) provided on the side surface of the main body portion, The light emitting unit is A groove portion (11) formed on the side surface of the main body portion along the longitudinal direction of the main body portion; A light emitting device (21) disposed in the groove; and a light-emitting portion cover (25) made of a light-transmitting material that covers the groove portion. Effect of the Invention

[0009] The position display device of the above embodiment has improved visibility at night or in dark places by lighting up the light emitting unit. The light emitting device constituting the light emitting unit is provided in a groove formed on the side of the rod-shaped main body, and does not protrude from the main body. Therefore, when placed on the ground, it is prevented from falling over due to the influence of strong winds or the inclination of the ground on which it is installed. Furthermore, since the position display device can be installed directly on the ground, no road cones are required, and it is easy to install and has excellent portability.

[0010] As described above, according to the above aspect, it is possible to provide a position indicator that is highly portable, has improved visibility, and is prevented from being damaged.

[0011] In addition, the symbols in parentheses described in the claims and the means for solving the problems indicate a correspondence with the specific means described in the embodiments described below, and do not limit the technical scope of the present invention.

[0013] The boundary position of the partitioned area may be a stopping position or a no-entry position for a work vehicle on a road or a work site, and the position display device may be placed on the ground of the road or the work site to display the stopping position or the no-entry position. This allows the position display device to improve the visibility of the stopping position or the no-entry position for a work vehicle. Furthermore, even if a work vehicle comes into contact with the position display device, the light-emitting device is provided in the groove and does not come into contact with the work vehicle, so damage to the light-emitting device is prevented. The driver of the work vehicle can recognize that the work vehicle has reached the installation position of the position display device without visually seeing it, due to the impact when the work vehicle comes into contact with or runs over the position display device.

[0014] The main body is provided with a control unit that controls the operation of the light-emitting device, and the control unit preferably includes a recess formed in the main body so as to communicate with the groove, a power supply unit disposed in the recess and supplying power to the light-emitting device, a control unit disposed in the recess and controlling the operation state of the light-emitting device, and a control unit cover that covers the recess. In this case, since no external power source is required to light up the light-emitting device, the position indicator can be installed even easier and the freedom of installation location is improved.

[0015] It is preferable that the main body has a plurality of side surfaces extending in the longitudinal direction, and the light emitting unit includes a first light emitting unit provided on one of the side surfaces of the main body, and a second light emitting unit provided on the side surface of the main body opposite to the side surface on which the first light emitting unit is provided. In this case, for example, since the light can be lit toward both the construction area side and the opposite side to the construction area, the boundary position can be clearly displayed for both areas.

[0016] At least one end of the main body has a connecting portion for connecting the plurality of position display devices to each other, and the light emitting devices provided in the plurality of position display devices are preferably configured to be able to conduct electricity to each other via the connecting portion. In this case, since the light emitting devices are each electrically connected by connecting the position display devices to each other, it is not necessary to provide a path for supplying power to each light emitting device individually, and therefore the configuration of the device can be simplified.

[0017] The connecting parts are preferably provided at both ends of the main body. In this case, any number of position display devices can be connected, improving the degree of freedom of installation. In addition, when multiple position display devices are connected, the control unit can be positioned on the inside in the longitudinal direction. This makes it difficult for the vehicle's tires to be positioned directly above the control unit when the vehicle runs over the position display device, and prevents damage to the control unit.

[0018] The position display device may be attached to a frame constituting a loading platform of a vehicle and configured to display the position of the loading platform. In this case, the position of the loading platform and the position of the vehicle can be displayed by emitting light from the light-emitting section, thereby improving the visibility of the vehicle at night or in a dark place.

[0019] (Embodiment 1) 1.Position display device 1 Hereinafter, an embodiment of the position display device will be described with reference to Figs. 1 to 7. The position display device 1 of this embodiment is placed on the ground and displays the boundary positions of the partitioned areas. More specifically, as shown in Fig. 1, the position display device 1 is placed on the road surface of a road 100 and displays the stopping position of a work vehicle 120 or a no-entry position for the work vehicle 120 as the boundary positions of the partitioned areas. The road 100 is not particularly limited, and may be a passageway through which vehicles can pass, such as a general road or expressway, or a passageway through which the work vehicle 120 passes at a construction site or the like. In this embodiment 1, the road 100 is a two-lane expressway, and includes a driving lane 101, an overtaking lane 102, and a median strip 103. A case in which road surface repairs or the like are being carried out in a construction area 104 of the overtaking lane 102 will be taken as an example.

[0020] In the passing lane 102, a traffic-restricted section 100a including a construction area 104 and a vehicle guidance section 100b just before the traffic-restricted section 100a are set. In the traffic-restricted section 100a, lane restrictions are imposed, and a traffic warden 110, a site supervisor 111, and a guide 112 are stationed. In the vehicle guidance section 100b, a number of arrow boards 113 for guiding vehicles traveling in the passing lane 102 in the direction of arrow P to the travel lane 101 and a regulation robot 114 are stationed. In addition, a regulation sign 115 indicating that the traffic-restricted section 100a is located a predetermined distance ahead of the vehicle guidance section 100b is installed.

[0021] The position display device 1 of this embodiment is installed on the road surface (ground) at the boundary between the traffic-restricted section 100a and the vehicle guidance section 100b, and at a position just before a construction area 104 within the traffic-restricted section 100a. The position display device 1 displays stopping positions and no-entry positions for a work vehicle 120, which is a sign vehicle having a portable sign, and is used to guide the work vehicle 120 to a predetermined position within the traffic-restricted section 100a together with a guide 112. As shown in FIG. 2, the position display device 1 includes a main body unit 10 and a light-emitting unit 20. The configuration of the position display device 1 will be described in detail below.

[0022] 2. Main body 10 As shown in FIG. 2, the main body 10 is rod-shaped and has a side surface extending in the longitudinal direction. In the present embodiment 1, the cross-sectional shape of the main body 10 is rectangular as shown in FIGS. 3 and 4. The material of the main body 10 is not limited, but wood, resin, metal, or a combination of a plurality of these materials can be used. In the present embodiment, wood is used as the material of the main body 10. In the present embodiment, the longitudinal direction of the main body 10 is X, the thickness direction (height direction) is Z, and the depth direction perpendicular to the longitudinal direction X and the thickness direction Z is Y. The length of the longitudinal direction X of the main body 10 is not limited, but can be, for example, a length equivalent to the vehicle width of the work vehicle 120. In addition, as described later, when a plurality of position display devices 1 are connected and installed, the length of the main body 10 can be set so that the overall length in the longitudinal direction X after connection is equivalent to the vehicle width.

[0023] The shape of the cross section of the main body 10 perpendicular to the longitudinal direction X is not limited, and may be a rectangle, a triangle, a circle, or a combination of these. In this embodiment 1, the cross section of the main body 10 is rectangular as shown in Fig. 3. As a result, the main body 10 has four side surfaces 10a, 10b, 10c, and 10d extending in the longitudinal direction X. In this embodiment 1, the main body 10 is solid as shown in Fig. 3, but instead, all or part of the main body 10 may be hollow.

[0024] The surface of the main body 10 is painted, and as shown in Fig. 2, the surface of the main body 10 has a color scheme in which red areas A and white areas B are alternately repeated in the longitudinal direction X. Note that the color scheme of the surface of the main body 10 is not limited to this, and may be, for example, a color scheme in which black areas and yellow areas are alternately repeated.

[0025] 3. Light emitting unit 20 The light emitting unit 20 is provided on a side surface extending in the longitudinal direction X of the main body 10. In the present embodiment 1, the light emitting unit 20 is provided on one side surface 10a of the four side surfaces 10a, 10b, 10c, and 10d of the main body 10 extending in the longitudinal direction X.

[0026] 3, the light-emitting unit 20 includes a groove 11 formed along the longitudinal direction X on the side surface 10a on which the light-emitting unit 20 is provided, a light-emitting device 21 disposed in the groove 11, and a light-emitting unit cover 25 made of a light-transmitting material that covers the groove 11. The width and length of the groove 11, i.e., the size in the depth direction Y and the size in the longitudinal direction X, are not limited, but are set to a size that can accommodate the light-emitting device 21 described below.

[0027] The configuration of the light emitting device 21 is not limited, and a known light emitting device can be used. In this embodiment, as shown in FIG. 5, an LED tape light 21 having a configuration in which a plurality of LEDs 23 are arranged and mounted at a predetermined interval on a flexible substrate 22 in the form of a flexible tape is used as the light emitting device 21. As shown in FIG. 3, the LED tape light 21 is fixed in the groove 11 by bonding the flexible substrate 22 and the bottom surface of the groove 11 to each other via a double-sided tape 24. The type of the LED 23 is not limited, and in this embodiment, a surface-mounted LED is used. The color of the light emitted by the LED 23 is not limited, but it is preferable to use a red LED for attention.

[0028] As shown in Fig. 5, in the LED tape light 21, the multiple LEDs 23 are connected in series to one another by printed wiring 221 formed on the flexible substrate 22. The flexible substrate 22 is provided with lands 212 and 213 for supplying power at positions sandwiching a cutting position 211. The LED tape light 21 can be cut at the multiple cutting positions 211 provided at predetermined intervals, and the LED tape light 21 can be cut to a desired length. After cutting the LED tape light 21 at the cutting position 211, power supply lines are connected to the lands 212 and 213 adjacent to the cutting position 211, making it possible to supply power to all of the LEDs 23 on the flexible substrate 22.

[0029] 3 covers the groove portion 11. The light-emitting unit cover 25 has translucency and is configured to transmit light emitted from the LEDs 23 to the outside. The material of the light-emitting unit cover 25 may be any material that has translucency, and in this embodiment, the light-emitting unit cover 25 is formed of an acrylic plate.

[0030] In this embodiment, as shown in FIG. 3, a step portion 11a is provided at the boundary between the groove portion 11 and the side surface 10a, forming a step equal to the thickness of the light-emitting unit cover 25. The light-emitting unit cover 25 is fitted into the step portion 11a to cover the groove portion 11. As a result, the light-emitting unit cover 25 is flush with the side surface 10a of the main body portion 10. The step portion 11a may be formed to have a step greater than the thickness of the light-emitting unit cover 25, so that the light-emitting unit cover 25 is recessed further into the main body portion 10 than the side surface 10a. In this case, when the work vehicle 120 runs over the position display device 1, the light-emitting unit cover 25 is less likely to receive a direct impact from the outside, and damage to the light-emitting unit cover 25 can be prevented. The light-emitting unit cover 25 can be fixed by a waterproof adhesive tape (not shown) and a fastening member such as a bolt (not shown).

[0031] The front or back side of the light-emitting unit cover 25 may be provided with a diffusion layer (not shown) for diffusing the light emitted by the LEDs 23. The diffusion layer may have a light-transmitting property and may have a fine lens shape, or may have a diffuser that diffuses the light emitted by the LEDs 23 and is arranged in a dispersed manner. The front or back side of the light-emitting unit cover 25 may be lens-processed, or a diffuser may be dispersed in the light-emitting unit cover 25 itself, to promote the diffusion of the light emitted by the LEDs 23. The light-emitting unit cover 25 may be made translucent and milky white to promote the diffusion of the light emitted by the LEDs 23. A reflective material may be provided on the wall surface of the groove portion 11 to promote the extraction and diffusion of the light emitted by the LEDs 23.

[0032] 4. Control Unit 30 In this embodiment, a control unit 30 is provided for supplying power to the light emitting device 21. The location where the control unit 30 is provided is not limited, but in this embodiment 1, it is provided at one end of the main body 10 in the longitudinal direction X. As shown in Fig. 4, the control unit 30 includes a recess 12 formed in the main body 10, a power supply unit 31, a control device 32, and a control unit cover 35. The recess 12 communicates with the groove 11 and opens to the side surface 10a (the upper side of the paper in Fig. 4).

[0033] The power supply unit 31 can be configured with batteries, and in this embodiment, is configured with two rechargeable secondary batteries. There are no limitations on the type of battery used as long as it can supply the power necessary to light the light-emitting device 21. The secondary battery that constitutes the power supply unit 31 is detachably held via a battery holder 33 fixed in the recess 12. Note that, instead of configuring the power supply unit 31 with batteries, the power supply unit 31 may be configured with an external power input unit that can input external power. The external power can be supplied by a commercial power source or an external battery.

[0034] The control device 32 is connected to the power supply unit 31 and the light emitting device 21, and controls the supply of power from the power supply unit 31 to the light emitting device 21. In this embodiment, the control device 32 is connected to the power supply unit 31 via a first connection terminal 311 provided on the battery holder 33, and is connected to the light emitting device 21 via the lands 212 and 213 of the light emitting device 21 via a second connection terminal 312. The control device 32 is connected to a switch 34 (see FIG. 2) provided on the side surface 10d of the main body 10, and the supply of power to the light emitting device 21 is switched on and off in response to the operation of the switch 34.

[0035] A changeover switch (not shown) is connected to the control device 32, and the changeover switch is configured to be able to change the lighting pattern of the LEDs 23 in the light-emitting device 21. The lighting pattern of the LEDs 23 is not limited, but examples of lighting patterns include constant lighting, blinking, and lighting only at a specified time so as to be lit only at night. Also, a lighting pattern in which the multiple LEDs 23 are lit and / or turned off in the order in which they are arranged on the flexible substrate 22 from one end to the other can be adopted.

[0036] The control unit cover 35 is detachably attached to the main body 10 so as to cover the recess 12. The control unit cover 35 may be either light-transmitting or non-light-transmitting. Making the control unit cover 35 detachable facilitates replacement of the battery constituting the power supply unit 31.

[0037] 5. Usage The manner of use of the position display device 1 of this embodiment 1 will be described below. As shown in Fig. 1, the position display device 1 is used to display the stopping position of a work vehicle 120, and to display no-entry positions into a construction area 104 or the like. The position display device 1 is used by placing it directly on the road surface so that the side surface 10b or 10d shown in Fig. 2 contacts the road surface of the road 100, with the light emitting unit 20 facing the target work vehicle 120. In this embodiment, as shown in Fig. 1, the position display device 1 is arranged so that the longitudinal direction X (see Fig. 2) of the position display device 1 coincides with the direction of the width of the road 100.

[0038] In the first embodiment, the display device 100 is configured to display stopping positions for the work vehicle 120 and no-entry positions. However, the display device 100 can also be used to display boundary positions of areas partitioned for other purposes.

[0039] When the position display device 1 of the first embodiment is transported, it can be attached to a frame constituting the bed of the vehicle. For example, as shown in Fig. 7, holders 122 can be attached to the left and right of the upper part of a rear tailgate 121 constituting the frame of the bed of a work vehicle 120 having a bed, and the position display device 1 can be attached to the rear tailgate 121 via the holders 122. Alternatively, the position display device 1 can be attached to the upper part of a side tailgate 123 constituting the frame of the bed of the work vehicle 120.

[0040] Although the position display device 1 of the present embodiment 1 is used alone, it may be used by connecting a plurality of position display devices 1 together. In the modified embodiment 1 shown in Fig. 8, in the connecting portion 15 including a connecting protrusion 151 provided at one end 13 of the first position display device 1a and protruding in the longitudinal direction X, and a connecting recess 152 provided at the other end 14 of the second position display device 1b and recessed in the longitudinal direction X, the connecting protrusion 151 fits into the connecting recess 152 as shown by the arrow Q, thereby connecting the first position display device 1a and the second position display device 1b in the longitudinal direction X.

[0041] Furthermore, the connecting portion 15 includes a male connector 153 provided at the end 13 of the first position display device 1a and a female connector 154 provided at the end 14 of the second position display device 1b. The male connector 153 is electrically connected to the control device 32, and the female connector 154 is connected to the lands 212, 213 of the LED tape light 21. As the connecting protrusion 151 fits into the connecting recess 152, the male connector 153 is connected to the female connector 154, and the control device 32 of the first position display device 1a and the LED tape light 21 constituting the light-emitting device 21 of the second position display device 1b are electrically connected via the male connector 153 and the female connector 154, so that the power of the secondary battery 31 of the first position display device 1a can be supplied to the light-emitting device 21 of the second position display device 1b.

[0042] By adopting such a configuration in the first modified embodiment, it is possible to light up both the light emitting device 21 of the first position display device 1a and the light emitting device 21 of the second position display device 1b with the power of the secondary battery 31 of the first position display device 1a. Note that in the first modified embodiment, it is not necessary to provide the control unit 30 including the power supply unit 31 and the control device 32 in the second position display device 1b.

[0043] When two position display devices 1a, 1b are connected as in modified embodiment 1, each of the position display devices 1a, 1b only needs to have the configuration of the connecting portion 15 (connecting protrusion 151, connecting recess 152, male connector 153, and female connector 154) at least on one end. When three or more position display devices 1 are connected, at least one position display device 1 that is not at the end in the arrangement direction of the position display devices 1 has the configuration of the connecting portion 15 on both ends 13, 14.

[0044] 6. Effects Next, the effects of the position display device 1 of this embodiment will be described in detail. According to the position display device 1, the light emitting unit 20 lights up, improving visibility at night or in dark places. The light emitting device 21 constituting the light emitting unit 20 is provided in a groove 11 formed in the side surface 10a of the rod-shaped main body 10, and does not protrude from the main body 10. Therefore, when placed on the road surface, it is prevented from falling over due to the influence of strong winds or the inclination of the road surface on which it is installed. Furthermore, since the position display device 1 can be installed directly on the ground, no road cones are required, making it easy to install and highly portable.

[0045] In the first embodiment, the boundary position of the partitioned area is a stop position or a no-entry position for the work vehicle 120 on the road 100 or the work site, and the position display device 1 is placed on the ground of the road 100 or the work site to display the stop position or the no-entry position. This allows the position display device 1 to improve the visibility of the stop position or the no-entry position for the work vehicle 120. Furthermore, even if the work vehicle 120 comes into contact with the position display device 1, the light-emitting device 21 is provided in the groove portion 11 and does not come into contact with the work vehicle 120, so damage to the light-emitting device 21 is prevented. The driver of the work vehicle 120 can recognize that the work vehicle 120 has reached the installation position of the position display device 1 without visually seeing it due to the impact when the work vehicle 120 comes into contact with the position display device 1 or runs over the position display device 1.

[0046] In the first embodiment, the main body 10 is provided with a control unit 30 that controls the driving of the light-emitting device 21. The control unit 30 includes a recess 12 formed in the main body 10 so as to communicate with the groove 11, a power supply unit 31 disposed in the recess 12 and supplying power to the light-emitting device 21, a control unit 32 disposed in the recess 12 and controlling the driving state of the light-emitting device 21, and a control unit cover 35 that covers the recess 12. As a result, no external power source is required to light the light-emitting device 21, which makes it easier to install the position display device 1 and improves the freedom of installation location.

[0047] Furthermore, in the first modified embodiment, at least one end 13, 14 of the main body 10 has a connecting portion 15 for connecting the multiple position display devices 1a, 1b to each other, and the light-emitting devices 21 provided in the multiple position display devices 1a, 1b are configured to be able to electrically connect to each other via the connecting portion 15. As a result, by connecting the position display devices 1 to each other, the light-emitting devices 21 are electrically connected to each other, and therefore there is no need to provide individual paths for supplying power to each light-emitting device 21, thereby simplifying the configuration of the device.

[0048] Furthermore, in the first modified embodiment, the connecting portions 15 can be provided at both ends of the main body 10. This allows any number of position display devices 1 to be connected, improving the degree of freedom in installation. Furthermore, when multiple position display devices 1 are connected, the control unit 30 can be positioned on the inside in the longitudinal direction X. This makes it difficult for the tires of the work vehicle 120 to be positioned directly above the control unit 30 when the work vehicle 120 runs over the position display device 1, and prevents damage to the control unit 30.

[0049] In the first embodiment, the control unit 30 is provided at one end of the main body 10 in the longitudinal direction X. However, instead, the control unit 30 may be provided at the center of the main body 10 in the longitudinal direction X.

[0050] As described above, according to the above embodiment, it is possible to provide a position display device 1 that is highly portable, has improved visibility, and is prevented from being damaged.

[0051] (Embodiment 2) 9, the position display device 1 of the second embodiment includes a first light-emitting unit 201 equivalent to the light-emitting unit 20 in the first embodiment, and a second light-emitting unit 202 on a side surface 10c opposite to the side surface 10a on which the first light-emitting unit 201 is provided. The second light-emitting unit 202 has a configuration equivalent to that of the first light-emitting unit 201 provided on the side surface 10c. The other components are the same as those in the first embodiment, and therefore the same reference numerals as those in the first embodiment are used in the present embodiment and their description will be omitted.

[0052] According to the position display device 1 of the second embodiment, for example, by placing the side 10d of the main body 10 on the ground where the light emitting units 201, 202 are not provided facing downward, it is possible to light up both the construction area 104 side and the opposite side of the construction area 104. This makes it possible to clearly display the boundary position for both areas. Note that the second embodiment also provides the same operational effects as the first embodiment.

[0053] In the position display device 1 of the second embodiment, the first light-emitting unit 201 provided on the side surface 10a and the second light-emitting unit 202 provided on the side surface 10c may be illuminated in the same lighting pattern or in different lighting patterns.
