DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 is a case body integrally formed of aluminum die cast or hard plastic, and the case body 1 is formed in a cubic trapezoidal box shape with an open lower surface, and flange portions 2 are formed at lower edges of both ends. , 2 are extended, and mounting holes 3 are formed in the flange portions 2, 2, respectively. A slit-shaped notch 5 is formed at the lower edge of the front wall 4 of the case body 1.

Solar cells 6 and 6 are provided on the upper surface of the case body 1, and the solar cell 6 is made of resin lenses 7 and 7 having a semi-circular shape.
And the resin lenses 7 are fixed to the upper surface of the case body 1 by screws 8. Both end walls 9, 9 of the case body 1 are inclined forward by about 30 degrees.
Are provided with infrared sensors 10, 10. Also, 1
Reference numeral 1 denotes a light emitting diode provided on the front wall 4 of the case body 1.

A storage battery 12, which is charged by the electromotive force of the solar cells 6 and 6, is provided in the case body 1 so as to be supported on a stop plate 13 which is laid horizontally in the case body 1. Reference numeral 14 denotes a bottom plate having a round opening 15 formed in the center thereof. The bottom plate 14 has a step portion 16 formed on the inner wall surface of the case body 1 so as to be located above the notch 5 of the case body 1. An acoustic gap 18 having a thin width is formed in the lower portion of the bottom plate 14 by fixing the bottom portion with a screw 17. Then, a speaker 19 is screwed on the bottom plate 14 in accordance with the opening 15.
And the control boards 22, 23 on the bottom plate 14 on both sides of the speaker 19 with screws 21.
They are fastened to each other.

The storage battery 12 is charged in the daytime by the electromotive force of the solar cells 6 and 6. The storage battery 12 is provided with a circuit for preventing its overcharge. The storage battery 12
Is a 24-hour timer 2 provided on the control boards 22 and 23.
4, the vehicle approach detection circuit 25, the audio signal generation circuit 26, the audio signal amplification circuit 27, and the light emitting diode 11 can be supplied with operating power, respectively.

The 24-hour timer 24 has a setting switch 2
8 has a time setting function, a start time setting function, and an end time setting function that can be easily set. By setting the start time at 5 am and the end time at 9 pm, parking is prohibited only during the daytime. It is possible to set an arbitrary parking prohibited time zone. Further, the infrared sensors 10 and 10 are sensitive to the presence of a heating object that emits infrared rays within a radius of a few meters depending on the sensitivity setting, and detect infrared rays emitted from the engine when a vehicle enters the set parking prohibited area. A signal is output to the vehicle approach detection circuit 25. The vehicle approach detection circuit 25 distinguishes a vehicle that merely passes the point from a vehicle that is going to park by confirming that the signal is persistent for several seconds to several seconds with a built-in timer and generates a voice signal. It issues a command to the circuit 26.

This parking prohibition warning device is installed by inserting a tack 29 into the mounting hole 3 on the road curb 28 as shown in FIG. Then, when the vehicle stops before the parking prohibition warning device during the parking prohibition time zone preset in the 24-hour timer 24, the vehicle approach detection circuit 25 operates and the voice signal generation circuit 26 operates as shown in FIG. Is ordered. The voice signal generation circuit 26 is a semiconductor memory in which a voice signal having a warning such as "This place is prohibited to park" is pre-recorded. The voice signal is amplified by the voice signal amplification circuit 27 and generated from the speaker 19. It At the same time, the light emitting diode 11 blinks to warn the driver by light that parking is prohibited in this area.

As described above, since the infrared sensors 10 and 10 are provided at both ends of the case body 1, it is possible to detect a wide range depending on how the sensitivity is set. Further, the speaker 19 is provided downward on the bottom plate 14, and the generated sound is emitted forward through the acoustic gap 18 and the notch 5. For this reason, the speaker 19 can clearly convey the sound to the driver of the automobile or the like even though the speaker 19 is not facing the front. Also, the speaker 1
Since 9 is hidden in the upper part inside the notch 5, it is maintenance-free and operates normally for a long time without being damaged by dirt and raindrops on the road.

[0013]

As described above, since the parking prohibition warning device of the present invention is driven by the solar cell provided on the upper surface and is equipped with the infrared sensor, it does not require distribution line work, burial work, etc., and is simple. It has the advantage of being easy to install and easy to maintain. Further, since it is provided with a 24-hour timer so that it can be operated only during the prohibited parking period, it is possible to make settings according to the installation location and to have a wide range of use, which is a beneficial effect.
