Description

  The present invention relates to a cone-type security sign and a traffic regulation vehicle.

  When performing road construction, etc., cone-type security signs are placed so that no danger is generated by entering the construction site. In traffic control work at night and in tunnels, guidance was performed using not only cone-type security signs but also stick-shaped red flashing lights. Alternatively, the visibility is improved by attaching a red flashing light to a cone-type security sign.

  The self-luminous flashing display of Patent Document 1 can improve safety because it can be alerted by light emission by being attached to the upper end of the cone-type security sign. Moreover, the warning display cover of Patent Document 2 does not lose the warning display function regardless of the orientation of the cone-type security sign when the small bulb emits light by covering the cone outer peripheral surface of the cone-type security sign. Can be.

  On the other hand, as shown in Patent Document 3, the applicant of the present application proposes a traffic control vehicle in which a plurality of cone-type safety signs can be mounted on one traffic-controlled vehicle, and the cone-type security signs can be easily installed and removed. However, it has been put to practical use. Thereby, field work can be performed easily and more safely.

  However, the above-mentioned conventional self-luminous flashing indicator and warning display cover are troublesome to install on the cone-type safety sign, so that there is a problem that much labor is required for installation by the operator. Since installation work for each cone type security sign is required after the installation of the type safety sign, it was not sufficient in terms of ensuring safety.

  In other words, in order to attach the self-luminous flashing indicator to the cone-shaped security sign having a substantially triangular pyramid shape, it is necessary to tighten the bolts etc. according to the screw holes formed in the cone-type safety sign, Waste a lot of time and effort. The attached self-luminous flashing indicator is easy to receive wind force, and not only can it be blown away or fall down when a high-speed vehicle passes through the side, but when it falls, it can be easily hit against the road surface etc. There was also a risk of breakage. Further, since the cone-type safety sign cannot be stacked with the self-luminous flashing indicator attached to the cone-type safety sign, it is necessary to remove all the self-luminous flashing indicators at the time of removal.

  Similarly, in the warning display cover, the cover is attached to the cone-type safety sign after placing the cover sheet along the conical side surface of the cone-type safety sign, and then the battery holder is attached. It was inevitable that it took time and effort. In addition, the cover sheet, battery holder, and cap are not fixed to the cone-type safety sign, and are not suitable for stacking the cone-type security sign with these attached. Had to be removed.

  That is, in a traffic control vehicle in which a cone-type safety sign is safely and easily installed as in Patent Document 3, it is not possible to mount a conventional self-light-emitting blinking indicator or a cone-type safety sign with a warning display cover attached as it is. It was extremely difficult. For this reason, the cone-type security sign which has the light emission function which can be arrange | positioned easily in the traffic regulation vehicle like patent document 3, and can be removed is desired.

  The present invention has been made in consideration of the above-mentioned matters, and provides a corn-type safety sign and a traffic-controlled vehicle that are improved in visibility by light emission and can be stored in an overlapping manner, so that installation and removal are troublesome. The purpose is to do.

  In order to solve the above-mentioned problems, the first invention comprises a substantially conical cone body having an opening formed at the apex portion, and a light emitting unit fitted into the opening, and the light emitting unit emits light at least laterally. A light emitting element that emits light, a stacking detection unit that detects a stacking state of a plurality of cone bodies, and a light emission control unit that supplies power to the light emitting element when the stacking detection unit does not detect the stacking state. A corn-type security sign is provided (claim 1).

  Since the light emitting unit is fitted into the opening of the cone body, it does not come off easily. Even if the cone type safety sign rolls over with the light emitting unit attached to the cone body, the light emitting unit can be easily removed from the cone body. The cone body can be stacked one on top of the other with the light emitting unit attached. In addition, when the cone main body is stacked up and down, the light emitting units are also stacked in close contact with each other, so that the connected state of the cone main body and the light emitting unit can be stably maintained.

  The shape of the light-emitting unit is preferably such that it fits into the opening and does not protrude from the conical shape of the cone body, and more preferably, even if the cone-type safety sign falls, The size of the cone body is set so as not to be beaten. As a result, handling of traffic-restricted vehicles becomes easier, and it is possible to extend the service life.

  Furthermore, since the stacking detection unit detects the stacking state with the cone body stacked, the light emission control unit supplies power to the light emitting element when the stacking detection unit does not detect the stacking state, thereby displaying the cone type security sign. The light emitting element can be made to emit light only by being placed on the site, and the work on site can be reduced and the placement work can be facilitated. Next, by removing the cone-type security sign and stacking the cone main body, the power supply to the light emitting element can be stopped without performing a separate operation, and wasteful labor and power consumption can be eliminated.

  The stack detection unit stops the light from being blocked by the cone body of the upper cone-shaped safety sign by stopping the power supply to the light emitting element of the light emitting unit located below with the cone body stacked one above the other. Wasteful power consumption by the unit can be prevented.

  The cone body is preferably made of an elastic synthetic resin (commonly called a rubber cone) that does not easily elastically deform and break even if it is stepped on by a vehicle. The connecting portion between the unit and the cone body preferably includes a retaining portion that engages with the step portion by turning.

  In the case where the stack detection unit includes limit switches provided at the upper end and / or lower end of the light emitting unit, and power supply to the light emitting element is stopped by pressing the limit switch (Claim 2), Not only can the stacking state of the cone body be detected reliably, but the power supply can be stopped by a mechanical switch that turns on and off the mechanical contacts in the stacking state, so the standby current is zero. Is also possible.

  When the light emitting element is a light emitting diode and the power source of the light emission control unit is a battery attached to the lower end of the light emitting unit (Claim 3), the light emitting unit can be reduced in size and consumed. It can be used for a long time with minimal power consumption.

  The light emission control unit includes an optical sensor that measures ambient illuminance, and supplies power to the light emitting element when the measured ambient illuminance is equal to or less than a predetermined threshold (Claim 4). In addition, by turning on the light emitting element only when there is a sufficient effect due to light emission, it is possible to prevent wasteful power consumption due to light emission in an environment where it is not possible to improve the visibility due to light emission such as daytime.

  A second aspect of the present invention is a traffic control vehicle characterized by comprising a cone installation / removal device capable of stacking a plurality of the cone-type safety signs on a loading platform and installing and removing the cone-type safety signs. (Claim 5).

  The cone-type safety sign of the first invention stops emitting light by laminating the cone body, and restarts when the cone body is delaminated, so that the cone-shaped security sign is stored in a traffic-regulated vehicle. Then, the light emission of each of the stacked cone-type safety signs can be stopped, and the light emission can be resumed in a state where the cone-type safety signs are installed on the site. Therefore, it is possible to start the light emission of the cone type safety sign simply by placing the cone type safety sign using the cone installation / removal device, and stop the light emission when removing the cone type safety sign using the cone installation / removal device. Can be simplified.

  As described above, according to the first invention, it is possible to obtain a corn-type safety sign that is easy to handle and has improved visibility by light emission. The light emitting unit can be stacked and accommodated while attached to the cone body, and since the light emitting unit does not emit light in the laminated state, the effort required to install and remove the cone type security sign is minimal. Can be suppressed.

  According to the second invention, a plurality of cone-type security signs can be safely and quickly placed on the site and removed.

  Hereinafter, the structure of the cone-type security sign 1 and the traffic regulation vehicle 10 according to the first embodiment of the present invention will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, the cone-type security sign 1 of the present invention includes a substantially cone-shaped cone body 2 having an opening 2A formed at the apex portion, and a light emitting unit 3 fitted into the opening 2A. It consists of. The cone body 2 is elastically deformed even if a car collides, and thus is connected to a substantially conical portion 2B made of a synthetic resin that is elastic enough to absorb energy and hardly break, and a lower end of the substantially conical portion 2B. The end of the flange 2C is wide and has a weight that is not easily blown away by wind or the like even if a vehicle with a speed of about 100 km / h passes through the side.

  The opening 2A of the present embodiment is formed by expanding the diameter of the opening 2A at a lower end portion of the pair of grooves 2D into which the fitting piece 3A for fitting the light emitting unit 3 is inserted. A stepped portion 2E is formed.

  The light emitting unit 3 includes a flange 3B having an outer periphery that is approximately the same as the outer periphery of the opening 2A, and a battery box 3C that can be inserted into the opening 2A, and the battery box 3C includes the pair of fitting pieces. 3A is connected. 3D is a push button switch formed at the upper end of the light emitting unit 3, and is formed of a light transmissive resin capable of diffusing light from the light emitting elements in the flange 3B and the push button switch 3D light emitting unit to the side at least. Has been.

  As shown by the arrow X, the light emitting unit 3 is fitted by turning it about 90 ° clockwise, for example, in a state where the fitting piece 3A is inserted into the opening 2A in accordance with the phase of the groove 2D. The light emitting unit 3 can be secured to the cone body 2 by fitting the piece 3A to the step 2E. The flange 3B of the cone-type security sign 1 attached to the opening 2A is formed with a diameter equal to or smaller than the outer diameter of the opening 2A, and the height of the light emitting unit 3 is higher than that of the opening 2A. Only the height that can irradiate the section is formed so as to protrude from the opening 2A, so that it is hardly affected by the wind. However, the cone-type security sign 1 of the present invention can prevent the vehicle from moving or falling over due to wind.

  FIG. 3 is an enlarged longitudinal sectional view showing the main configuration of the cone-type security sign 1 including the light emitting unit 3, and is a longitudinal sectional view shown in FIG. 3 (A) and a longitudinal sectional view shown in FIG. 3 (B). Are different in cross-sectional angle by 90 ° in plan view. The light emitting unit 3 includes a light emitting diode (hereinafter referred to as an LED) 4 as an example of a light emitting element arranged to emit light at least to the side, and a spring 5 that urges the push button switch 3D upward. A limit switch that has a lever 6A that tilts when the push button switch 3D is pushed, and that functions as a stacking detection unit 6 that detects the stacking state of the plurality of cone bodies 2 by the tilting of the lever 6A, and the stacking detection unit 6 (Hereinafter referred to as a limit switch 6 in the present embodiment) a light emission control unit 7 that supplies power to the light emitting element when a stacked state is not detected, a substrate 8 to which the LED 4, the limit switch 6, and the light emission control unit 7 are attached; And a battery 9 for supplying power to the light emission control unit 7.

  3E is a circuit housing case capable of housing the substrate 8 and each of the electronic components 4, 6, and 7. 3F is a transparent lid for protecting the upper surface of the circuit housing case 3E. 3G is a contact between the circuit housing case 3E and the transparent lid. 3H is a screw that prevents the water from entering from the contact portion and 3H is a screw that attaches the push button switch 3D to the circuit housing case 3E via the flange 3C and the flange 3C, and 3I is a lid of the battery box 3C. is there. The battery box 3C and the circuit housing case 3E are integrally formed of synthetic resin, and the lid 3I is attached below the battery box 3C.

  FIG. 4 is a diagram illustrating a circuit configuration of the light emitting unit 3. In other words, the light emission control unit 7 is connected to the battery 9 via the contact b (normally closed) of the limit switch 6 and from the battery 9 only when the limit switch 6 is not operated (that is, when the stacked state is not detected). It is comprised so that the electric power of may be supplied. The light emission control unit 7 is a circuit that outputs a current necessary and sufficient to turn on the plurality of LEDs 4. Preferably, the LEDs 4 are intermittently blinked so that the power consumption can be reduced and the visibility can be improved. In addition, the light emission control unit 7 includes an optical sensor 7A that measures the ambient illuminance. When the ambient illuminance exceeds a predetermined threshold value (a threshold value indicating whether the ambient light is so bright that the light from the LED 4 is not noticeable), The power supply is configured to stop.

  For example, the LEDs 4 are connected in parallel to the light emission control unit 7 with the resistors 4A connected in series, so that the current flowing through the LEDs 4 is suppressed to a predetermined magnitude to prevent element damage and useless power. Consumption can be suppressed. In addition, although the figure shows an example in which four LEDs 4 are connected in parallel and irradiates light spreading in at least four directions, this number is not important for the present invention, and the number of LEDs 4 is increased. Needless to say, the visibility may be improved.

  According to the cone-type safety sign 1 having the above-described configuration, the limit switch 6 is in the on state when the push switch 3D is not pressed, so that power from the battery 9 is supplied to the light emission control unit 7 and the ambient illuminance is low. When the light emission control unit 7 falls below the threshold value, the light emission control unit 7 supplies power that causes the LED 4 to emit light intermittently, so that the light emitted from the LED 4 passes through the flange 3B, the push button switch 3D, and the transparent lid 3F. Diffuses towards. Thereby, the visibility of the cone-type security sign 1 is greatly improved.

  FIG. 5 is a view showing a state in which cone-type security signs 1 (1A, 1B) to which the light emitting unit 3 is attached are stacked and accommodated. As shown in FIG. 5, when a plurality of cone-type security signs 1A, 1B,... Are stacked and stored, the light emitted from the light-emitting unit 3 of the lower cone-type security sign 1B is the cone-type security sign arranged above. Since it is obstructed by the cone body 2 of 1A, this cannot be seen from the surroundings, but the push button switch 3D of the light emitting unit 3 located below is in contact with the lid 3I of the upper light emitting unit 3 and presses it down. Therefore, the light emission of the lower light emitting unit 3 is stopped.

  The vertical width of the light emitting unit 3 (distance from the push switch 3D to the lid 3I) is the same as or slightly shorter than the vertical width of the flange 2C of the cone body 2, so that the push switch 3D is formed. In the stacked state, the push switch 3D can be surely pushed and operated without applying a large force to the.

  That is, in a state where a plurality of cone-type safety signs 1A, 1B,... Are stacked, only the light-emitting unit 3 of the cone-type safety sign 1A located at the uppermost side emits light, so that wasteful power consumption can be prevented. In order to stop the light emission of all the cone-type safety signs 1 such as when all the cone-type safety signs 1 are stored, the push switch 3D of the uppermost cone-type safety sign 1A can be kept depressed. A simple cover (not shown) can be attached.

  FIG. 6 is a diagram showing a configuration of a traffic regulation vehicle 10 that can be mounted on a cargo bed with a plurality of cone-type security signs 1 stacked thereon.

  As shown in FIG. 6, the traffic control vehicle 10 includes a cone installation / removal device 11 that enables installation and removal of the cone-type security sign 1 (1A, 1B...), And a plurality of cone-type security signs 1 ( 1A, 1B,...) And a conveyor device 12 configured to be movable in the front-rear direction of the loading platform 10A, and the loading platform 10A and the cone installation / removal device of the traffic regulation vehicle 10 while separating the plurality of road signs 13 from each other. 11 and a holding portion 14 that can be held in a state separated from 11.

  The holding portion 14 is rotatably supported so as to be movable to the rear position P1 and the upper position P2 of the loading platform 10A while holding the plurality of road signs 13. The cone installation / removal device 11 has a hand portion 15 that moves while gripping the cone-type security sign 1 when the cone-type security sign 1 is installed or removed. As this cone installation / removal device 11, a device having a known configuration can be used. For example, a road sign installation / recovery device described in Heisei 5-65709 can be used.

  By using the traffic regulation vehicle 10 having the above-described configuration, the cone-type safety sign 1 can be safely, reliably, and quickly placed on the road surface of the site.

  7 and 8 are views showing the configuration of the cone-type security sign 20 of the second embodiment, FIG. 7 is a longitudinal sectional view, and FIG. 8 is a circuit diagram. In addition, in the following description, since the member which attached | subjected the same code | symbol as 1st Embodiment is the same or equivalent member, the detailed description is abbreviate | omitted.

  In the cone-type safety sign 20 of the second embodiment, 21 is an extension bar attached to the center of the lid 3I, and 22 is a tact switch that is pushed when the extension bar 21 is pushed up. The extension rod 21 is biased downward by a spring 21A, and 21B is a split pin for preventing the extension. Further, as shown in FIG. 8, the tact switch 22 is provided with a b contact (normally closed) that constitutes a part of the stack detection unit by being connected in series with the limit switch 6.

  The cone-type security sign 20 having the above configuration stops light emission of the issuing unit 3 when the adjacent cone-type security sign 20 is loaded in any direction. Therefore, when the cone-type safety sign 20 is stored in a stacked state, the light emitting unit 3 located at the uppermost part does not emit light, so it is removed from the site and placed on the loading platform 10A of the traffic regulation vehicle 10. The light emission of all the cone-type security signs 20 can be stopped at the time of mounting. That is, there is an advantage that it is not necessary to perform any troublesome power management.
