Field of industrial application) The present invention relates to a novel vehicle-mounted revolving light. Specifically, it consists of a base fixed to the roof of the vehicle, a glove formed into a cylinder made of transparent material and attached to the base, and a light source, a reflector, etc. that are removably attached to the glove. To provide a novel vehicle-mounted revolving light which is equipped with a unit stand supporting a rotating unit, in which a globe of a desired length can be easily obtained, and the globe has excellent strength. That is.

(B. Summary of the Invention) The vehicle-mounted revolving light of the present invention connects a plurality of short cylindrical globe elements in the axial direction to form a globe of a desired length, and connects the plurality of globe elements in the axial direction on the inner surface of each globe element. A plurality of connecting ridges are formed that are aligned in the axial direction to form a plurality of connecting ridge rows when arranged in a row, and a single connecting frame strip is connected to each of these connecting ridge rows in a fitting manner. By adjusting the number of glove elements to be connected, it is possible to easily obtain a glove of a desired length, and it is also possible to easily obtain a glove of a desired length by adjusting the number of glove elements to be connected. Since each of the single connecting frame strips is connected in a fitting manner, the strength of the glove consisting of a plurality of glove elements is sufficient.

(C. Prior Art) [FIGS. 14 and 15] Conventionally, there is a type of vehicle-mounted revolving 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 or the like; c is a glove fixed on the base b; d is a unit base detachably mounted inside the glove c;
A rotating unit e consisting of a light bulb, a reflecting mirror, etc. is supported on the unit stand. f is an outer cover that closes the outer opening of the glove c.

The globe c is made up of a plurality of short cylindrical globe elements g, g, . . . connected in the axial direction.

A plurality of bosses h, h, ... extending in the axial direction are formed on the inner surface of each globe element g,
The bosses h, h, ... have bolt insertion holes i, i, ...
...is installed throughout.

And a plurality of globe elements g, g,...
When the ... are arranged in the axial direction, the respective bosses h, h, ... formed thereon are aligned in the axial direction to form a plurality of boss rows. Therefore, long connecting bolts j,
j, . . . are inserted from one end side, and the tips of the connecting bolts j, j, . . . are screwed into nuts k, k, . As a result, a plurality of globe elements g, g, . . . arranged in the axial direction are combined to form a globe c.

(D Problems to be solved by the invention) [No. 14
[FIG. 15] By the way, the above-mentioned conventional vehicle-mounted revolving light a has a problem in that the strength of the globe c is unsatisfactory.

That is, in the case of the above structure, the connecting bolts j,
Since there is inevitably a slight gap between the bolt insertion holes i, i, ... and the bolt insertion holes i, i, ..., if the glove c is held up by one end, the connecting bolts j, j, ... The problem is that the load is concentrated at the locations where both ends of the bosses are connected, that is, at both ends of the boss row, and the locations where this load is concentrated are likely to be damaged. Also, the load on the globe c is the connecting bolt j,
There is also the problem that the connecting bolts j, j, . . . are required to have considerable strength.

(E. Means for Solving Problems) In order to solve the above-mentioned problems, the vehicle-mounted revolving light of the present invention connects a plurality of short cylindrical globe elements in the axial direction to form a globe of a desired length. A plurality of connecting protrusions are formed on the inner surface of each glove element, which are aligned in the axial direction to form a plurality of connecting protrusion rows when the plurality of globe elements are arranged in the axial direction. Each of these is a single connecting frame connected in a fitting manner.

Therefore, according to the vehicle-mounted revolving light of the present invention, when the glove is lifted by holding one end, the load is applied over the entire length of the connecting protrusion row and the connecting frame row.
The load is distributed and there is no local concentration.
Therefore, there is no possibility that a strength weakness will occur in a specific part of the glove.
