DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, reference numeral 1 denotes a cone, which is a main body 2 made of a hard rubber or a synthetic resin and having a truncated cone shape.
And a substrate 3 integrally formed underneath with the same material. A hole 4 with a specified size is provided on the top of the main body 2.
Is provided.

Reference numeral 5 is a road warning device according to the present invention (hereinafter,
It is called an alarm device). This alarm device 5 is
A cylindrical portion 6 having an outer diameter that can be inserted into the hole 4 in the upper portion of the cone 1, a flange 7 of an elastic material (for example, a plate material made of hard rubber, synthetic resin, or the like) positioned at the upper end of the cylindrical portion 6, and a flange 7 It consists of a case 8 located at the top.

The flange 7 is circular and has an area larger than the bottom area of the rectangular case 8 and projects outward from the outer periphery of the case 8 in all parts. This is to prevent the case 8 from directly hitting the road surface when the alarm device 5 falls down together with the cone 1 as described later. The elastic material is used in order to absorb the impact at the time of falling.

Inside the tube portion 6, a plurality of rechargeable batteries 9 are stored in tandem. In the embodiment, 6 volt is obtained by using five electromotive force of 1.2 volt. Since the battery 9 has an appropriate weight, when the tube portion 6 is inserted through the hole 4 of the cone 1, the alarm device 5 and the cone 1
The center of gravity of the composite body of will be located at an appropriate position. As a result, the vehicle does not fall in the normal state, and easily falls when the vehicle comes into contact therewith.

The case 8 is a rectangular parallelepiped, and a hole 10 is formed on one surface, for example, a side surface of the case 8, so that the sound of a horn 11 (see FIG. 2) provided inside can be easily emitted to the outside. ing. The drilling place is not limited to one side surface, and may be the entire circumferential surface.

The power switch 12 is provided on the surface of the case 8.
A lamp 13 that is turned on when the power switch 12 is pressed and turned on is attached.

As shown in FIG. 2, a frame 14 is provided inside the case 8, and a horn 11 and a control device 15 are attached to the frame 14. The horn 11 operates at a voltage of 6 V and is large (10
(About 0 horn) And it is used for motorcycles that emit sounds in the high range. The control device 15 includes a mercury switch 16 (see FIG. 3) as a tilt detection switch, and an electronic circuit 17 (FIG. 3) that amplifies the weak current when the mercury switch 16 is turned on and operates the horn 11. reference)
Have.

FIG. 3 is a circuit diagram of the controller 15. In this figure, reference numeral 16 denotes a mercury switch, which functions as a tilt detection switch that is turned on when the cone 1 is tilted by a predetermined angle. The mercury switch 16
The electrode provided in the container is turned on and off by the mercury contained in the container, and is turned on when the container is tilted by about 60 degrees. It remains off when the container is upright or tilted below 60 degrees.

Reference numeral 17 is an electronic circuit. This electronic circuit 17
As described above, when the electrode of the mercury switch 16 is turned on by mercury, the weak current is amplified and the alarm 1
1 is operated. An interrupting circuit 18 is connected next to the electronic circuit 17 so that energization of the horn 11 can be switched between continuous and intermittent. It is practically preferable that the interval in the case of interruption is at least about 2 to 5 seconds. Since the on / off circuit 18 has a short on-time of about 2 to 5 seconds, an electronic one such as a flip-flop circuit can be considered. If it is not necessary to make the connection / disconnection, the connection / disconnection circuit 18 becomes unnecessary.

The road alarm device thus constructed is used when an accident occurs on a highway or the like and a police officer handles it, or at a road construction site. As in the conventional method, the cone 1 is placed near the site or a little further away from the site as in the conventional case, the tube portion 6 of the alarm device 5 is inserted through the hole 4 at the upper end, and the alarm device 5 is attached to the upper end of the cone 1.
Is installed. After installation, the power switch 12 is turned on, and the operation of the horn 11 is selected to be continuous or intermittent.

If the cone 1 having the alarm device 5 set near the accident site or the road construction site is not overturned by the runaway vehicle, the mercury switch 16 will remain off, so the alarm device 5 will issue an alarm. No sound will be emitted. At this time, since there is no runaway vehicle, police officers etc. can concentrate on the accident handling work. When the vehicle from the rear ignores the accident display and the road construction display, or if the cone 1 is tilted over the course, the case 8 provided above it also falls on the road surface. A flange 7 made of an elastic material is provided in the lower portion of the case 8, and since the flange 7 is larger than the bottom area of the case 8, when the cone 1 falls, the flange 7 first collides with the road surface to cause an impact. Relieve Therefore, the case 8 and the internal parts thereof are not damaged or broken down.

When the cone 1 falls down, the mercury switch 16 inside the case 8 operates. That is, as described above, the mercury switch 16 is set so that when the container is tilted at a predetermined angle, for example, 60 degrees from the upright state, the mercury comes into contact with the electrodes and short-circuits the electrodes. Since the cone 1 is mounted so as to be in the upright state when it is in the upright state, the cone 1 is naturally turned on when the cone 1 falls down.

When the alarm device 5 is activated and the horn 11 emits a sound, the cone 1 is tilted down and the vehicle continues to run in the same path. Then, the vehicle collides with a police vehicle or the like that has been stopped for accident handling. However, since it poses a danger to the police officers and the like who are handling the accident in front of them, the police officers and others immediately evacuate when they hear the sound of the horn 11. Whether the sound of the horn 11 is a continuous sound or an intermittent sound is appropriately selected according to the situation of the place.

Although the flange 7 is circular in the structure shown in FIG. 1, the present invention is not limited to this. Since it suffices that all the parts project outward from the case 8, a rectangular shape similar to the plan shape of the case 8 and having a larger area than this may be used.

FIG. 4 shows an embodiment in which the present invention is applied to a cone having no hole at the upper end. If the cone 1 does not have a hole at the upper end, the cone 1 is covered with a frame-shaped holding body 19 from above (see FIG. 5), and the barrel portion 20 located above the holding body 19 is fitted with a barrel of the case 8. The part 6 will be fitted. As the holding body 19, a frame-shaped one in which the cylindrical portion 20 and the lower ring 21 are connected by four columns 22 is used in the illustrated one, but is not limited to such a frame-shaped structure. In short, the point is that the cylindrical portion 20 is provided on the upper portion and has a size that can be exactly mounted on the cone 1.

In this embodiment as well, since the alarm device 5 part is the same as that shown in FIGS. 1 and 2, the operation is exactly the same.

In all of the embodiments described above, the alarm device 5 is attached to the upper portion of the cone 1 for use, but the present invention is not limited to this. Since the cone 1 is a cavity, the cavity 5 can be used to house the alarm device 5 inside the cone 1. FIG. 6 shows an embodiment in that case. In this example,
A flange 23 is formed on a part of the tubular portion 6 and a male screw 24 is engraved at the tip of the flange 23 so that the whole alarm device 5 can be inserted into the hole 4 from below the cone 1.

When the flange 23 hits the upper edge of the cone 1, it is pressed down, and the nut 25 is screwed onto the male screw 24 to attach it. Also in this embodiment, since the battery 9 is located above the cone 1, the center of gravity becomes high. Reference numeral 26 is a hole for making a sound from the horn 11. Also in the case of this embodiment, there is no difference in the method of use and the effect thereof from the previous embodiment.

The present invention is intended to avoid the danger of a worker such as a police officer who is handling an accident in front of the cone 1 when the cone 1 is knocked down by a runaway vehicle.
The main means is to use the alarm sound emitted at the position of the cone 1, but the alarm sound emitted at the position of the cone 1 may or may not be heard by the worker depending on the surrounding conditions.

FIG. 7 shows an embodiment for coping with this case. In this embodiment, the electronic circuit 1
Connect the oscillator 27 together with the intermittent circuit 18 in the latter stage of 7,
When the mercury switch 16 is turned on, from that point,
Radio waves are radiated from the antenna 28. In this case, the police officer or the like should make a speaker of the receiver emit a sound when carrying the receiver and receiving a radio wave. The action after hearing this sound is the same as in the previous embodiment.

In the embodiment described above, the independent interrupting circuit 18 is provided so that the sound of the horn 11 can be interrupted, but the present invention is not limited to this. The intermittent circuit may be configured purely electronically and incorporated in the electronic circuit 17. As mentioned above, the horn 1
The sound 1 is always emitted continuously, and the interrupting circuit 18 is not necessary when it is not necessary to interrupt the sound.

[0043]

As described above, the present invention is a road warning device constructed as described above. Therefore, even if a runaway vehicle runs, it is sufficient to evacuate if the sound of the horn is paid attention. You will get the time. Since the sound of the horn can be selected from continuous sound and intermittent sound, it can be set to be easier to hear in the situation of the accident processing site. Since the existing cone can be used as it is, it can be easily set at the accident site and can be used immediately. Since the alarm device can be attached to and detached from the cone, it has excellent transportability. Also, since the battery is housed in the cylinder,
It is possible to obtain a center of gravity with an appropriate height so that the vehicle does not normally fall, but falls when a runaway vehicle comes into contact with it. Since the flange is made of an elastic material, it has a cushioning effect when it falls, and it is possible to prevent the case and the inside of the case from being damaged or malfunctioning. The one using the holder can be easily applied to a cone having no hole at the upper end. With the switch mechanism and horn inside the cone,
Since the overall dimensions are exactly the same as the cone, it is easy to store. Since the mercury switch is used as the switch mechanism, it can be activated and reset quickly and reliably.
With the use of radio waves, it becomes more certain that the runaway vehicle has arrived.
