Overview of a vehicle-mounted warning light. b Base c Globe c-1 Inner cover c-2 Connection bolt c-3 Outer cover d Unit stand G Effects of the Invention (A. Field of Industrial Application) The present invention relates to a novel vehicle-mounted warning light. Specifically, it consists of a base fixed to the roof of the vehicle, a sound generator supported at the center of the base, a cylindrical glove supported on both sides of the base with the sound generator in between, and the glove. In a vehicle-mounted warning light that has a warning light unit housed inside and a concave portion extending in the longitudinal direction in the base, water such as rainwater that has entered the part where the sound generator is located can be prevented from being disposed of by the glove. The purpose of this project is to provide a new vehicle-mounted warning light that prevents intrusion into the parts of the vehicle.

(B. Summary of the Invention) In the vehicle-mounted warning light of the present invention, a drainage hole is formed in a portion of the concave portion extending in the longitudinal direction of the base that supports the glove and the sound generator, in a portion corresponding to the sound generator placement portion. An elastic protrusion protruding downward from the lower edge of the inner cover that closes the inner end of the glove is formed, and the protrusion corresponds to the part of the recess corresponding to the sound generator arrangement part and the glove arrangement part. By this, water that has entered the part corresponding to the sound generator placement part can be quickly drained out of the base through the drainage hole, and even water that has not been drained can be Intrusion into the portion corresponding to the glove placement portion is prevented by the protruding piece of the inner cover.

(C. Prior Art) [Figs. 14 and 15] Conventionally, there is a vehicle-mounted warning light mounted on the roof of a vehicle such as an automobile, as shown in Figs. 14 and 15.

b is a base fixed to the roof of a car, c, c
is a globe fixed on the base b, d is a unit stand detachably mounted inside the globe c, and the unit stand d supports a rotating unit e consisting of a light bulb, a reflector, etc. There is. f is an outer cover that closes the outer opening of the glove c.

g, g are loudspeakers placed in the center of base b;
h is a recess provided on the upper surface of the base b, and necessary electronic components i, i, . . . are arranged in a portion of the recess h located below the globes c, c.

In addition, j is the center part of the base b, that is, the loudspeakers g, g
This is a cover that covers the part on which the loudspeakers g and g are placed, and has a large number of small holes k, k, .

(Problem to be solved by the invention D) In the vehicle-mounted warning light a as described above, the base b
Since the gloves c and c are formed with consideration to relative waterproofness, rainwater does not directly enter the part where the gloves c and c are provided, but they cover the center part of the base b. The attached cover j has a large number of small holes k, k, ... formed therein so that the sound emitted from the loudspeakers g, g can be clearly transmitted to the outside, so these small holes k, k, ... Rainwater can easily enter.

If rainwater enters the center part of the base b, the concave part k where the electronic components i, i,...
is continuous from one end of base b to the other (base b
This is because they are made of extrusion molded products such as aluminum to reduce costs. ), there is a risk that rainwater will enter the parts where the electronic components i, i, etc. are arranged, and the functions of the electronic components i, i, etc. will be impaired.

Of course, the above problem can be solved if a means for waterproofing is separately provided between the central part of the recess h and the part where the electronic components i, i, etc. are arranged, but such waterproofing There is a problem in that this requires extra means and effort to attach it, resulting in a significant increase in cost.

(E. Means for Solving the Problems) In order to solve the above-mentioned problems, the vehicle-mounted warning light of the present invention has a recess formed in the base supporting the glove and the sound generator so as to extend in the longitudinal direction. A drainage hole is formed in the part corresponding to the sound generator placement part,
An elastic protrusion is formed that protrudes downward from the lower edge of the inner cover that closes the inner end of the glove, and the protrusion allows a portion of the recess corresponding to the sound generator placement portion and a portion corresponding to the glove placement portion to be formed. This is a watertight barrier between the two.

Therefore, according to the vehicle-mounted warning light of the present invention, rainwater that has entered the central portion is first drained to the outside through the drainage hole formed there. In addition, an elastic protrusion provided on the inner cover that closes the inner end of the glove creates a barrier between the part of the recess provided in the base that corresponds to the sound generator placement part and the part that corresponds to the glove placement part. Therefore, even a small amount of rainwater remaining in the center part will not enter the part of the recess corresponding to the glove placement part.

Moreover, the water shielding between the part of the recess corresponding to the sound generator placement part and the part corresponding to the glove placement part is done at the same time as the glove is attached to the base. It has the advantage that it does not require any special effort and does not result in a significant increase in cost.

(G Effect of the Invention) As is clear from the above description, the in-vehicle warning light of the present invention includes a base fixed to the roof of the vehicle, a sound generator supported at the center of the base, It is equipped with a cylindrical glove supported on both sides of the base with the sound generator in between, and a warning light unit housed in the glove, and the base is formed with a recess extending in the longitudinal direction. A drainage hole is formed in the central part where the sound generator is supported, and an elastic protrusion protruding downward from the lower end of the inner cover that closes the inner end of the glove is formed, and the protrusion is used to drain the recess. The device is characterized in that the sound generator support part and other parts are watertightly isolated.

Therefore, according to the vehicle-mounted warning light of the present invention, rainwater that has entered the central portion is first drained to the outside through the drainage hole formed there. In addition, an elastic protrusion provided on the inner cover that closes the inner end of the glove creates a barrier between the part of the recess provided in the base that corresponds to the sound generator placement part and the part that corresponds to the glove placement part. Therefore, even a small amount of rainwater remaining in the center part will not enter the part of the recess corresponding to the glove placement part.

Moreover, the water shielding between the part of the recess corresponding to the sound generator placement part and the part corresponding to the glove placement part is done at the same time as the glove is attached to the base. It has the advantage that it does not require any special effort and does not result in a significant increase in cost.
