BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a new vehicle-mounted warning light. More specifically, the invention relates to a vehicle-mounted warning light including a base fixed to a vehicle body, a glove containing a warning unit, and a cover having a curved side surface with a sound emission hole formed to cover a speaker placement portion of the base. , It aims to provide a new in-vehicle warning light with an extremely simple structure that can prevent snow and water that have entered the inside of the cover through the sound emission hole from entering the speaker horn of the speaker. Is.

[0002]

2. Description of the Related Art As an on-vehicle warning light mounted on the roof of a vehicle such as an automobile, there is one as shown in FIG.

B is a base fixed to the roof of an automobile,
Reference characters c and c'represent the speakers fixed to the central portion of the base b, with the speaker c arranged frontward and the speaker c'arranged rearward.

Reference numeral d denotes a cover attached to the base b so as to cover the speakers c and c ', and the front and rear surfaces of the cover d are for improving the transparency of the sounds of the speakers c and c'. A large number of sound emission holes e, e, ... Are formed.

Reference numerals f, f denote gloves arranged on both sides of the base b with a speaker arrangement portion at the center interposed therebetween. Inside the gloves f, f, there is an unillustrated warning unit including a light bulb, a reflecting mirror and the like. It is arranged.

However, the on-vehicle warning light a as described above is used by being mounted on the roof of an emergency vehicle such as a police car or a fire engine, and visually appealed when the warning unit in the gloves f, f emits light. In addition, by sounding the speakers c and c ', it is possible to appeal to the hearing and inform surroundings of the approach of the emergency vehicle.

[0007]

By the way, the cover d of the above-mentioned vehicle-mounted warning light a is provided with sound emission holes e, e, ... To improve the transparency of the ringing sound of the speakers c, c '. Since it is formed, fine snow and rainwater enter the inside of the cover d through the sound emission holes e, e, ... And further enter the speaker horns g and g ′ of the speakers c and c ′. There is a problem.

The intrusion of snow or water into the speaker horns g and g'not only causes the failure of the speakers c and c ', but also when the snow stays in the speaker horns g and g', the speaker c and There is a problem that the ringing of c ′ itself is disturbed.

[0009]

In order to solve the above-mentioned problems, the vehicle-mounted warning light of the present invention has a speaker horn front face of a speaker covered with a cover having a large number of sound emission holes. A mesh-like material that is stretched on the frame that is attached to the front end and has a sound-transmitting property and does not easily adhere to snow.
While covering with a sheet, insert the inside of the cover from the sound output hole of the cover.
The trough-shaped recess where the water that entered the part gathers protrudes below the base.
It is formed by the side edge part that is projected and the lower end part of the cover .

[0010]

Therefore, in the vehicle-mounted warning light of the present invention, even if snow or water enters the inside of the cover through the sound output hole of the cover, the front surface of the speaker horn is covered by the sheet, Rutotomoni water can be prevented from entering up to the speaker horn, the inside of the cover
The water that has entered can be collected in a trough-shaped recess. Further, since the above-mentioned sheet has a sound-transmitting property, it does not prevent the sounding of the speaker from reaching a long distance. Further, since the sheet is difficult for snow to adhere to, snow and water adhere to it. It does not interfere with its sound permeability.

Further, since the seat is hidden in the cover, it can be carried out not only during snowfall but also over the whole season without spoiling the appearance of the vehicle-mounted warning light.

Also, the snow and rainwater that have entered the speaker covers 28, 28 'are collected in the above-mentioned trough-shaped recesses 33, 33'.
It can also be Mel.

[0048]

As is apparent from the above description, the in-vehicle warning light of the present invention is a base fixed to a vehicle body, and fixed to both sides of the base, and a warning unit is housed therein. And a cover with a curved side shape in which a large number of sound emission holes covering the speaker arrangement portion in the central portion of the base are formed over a wide area, and the front surface of the speaker horn of the speaker is provided. It has a sound transmission and is covered with a frame attached to the front end of the speaker horn, and snow
Cover with a mesh-like sheet that does not easily adhere and cover
Gutter shape that collects water that has entered the inside of the cover through the sound output hole of
Side edge that protrudes the concave part of the base below the base and the lower end of the cover
It is characterized in that it is formed by a part .

Therefore, in the vehicle-mounted warning light of the present invention, even if snow or water enters the inside of the cover through the sound output hole of the cover, the front surface of the speaker horn is covered with the sheet, so Water can be prevented from entering the speaker horn, and the inside of the cover
The water that has entered the part can be collected in the trough-shaped recess.

Since the above-mentioned sheet has a sound-transmitting property,
It does not prevent the sound of the speaker from reaching a long distance, and furthermore, since snow is not easily attached to the sheet, there is no possibility that snow or water will adhere to it and impair its sound permeability.

Further, since the seat is hidden in the cover, it can be carried out not only during snowfall but also over the whole season without spoiling the appearance of the vehicle-mounted warning light.

In the above embodiment, the wire mesh is used as the sheet having the sound transmission property and the snow is hard to adhere thereto. However, this sheet is not required to be the wire mesh, and it has the sound transmission property and the snow. Any material that does not easily adhere may be used. For example, a mesh-like cloth body formed of water-repellent fibers, a mesh-like cloth body subjected to a water-repellent treatment, or the like can be used.

The above embodiment is merely an example of the embodiment of the present invention, and the technical scope of the present invention should not be limitedly interpreted by this.
