Description

[Detailed description of the invention] The vehicle-mounted revolving light of the present invention will be explained according to the following items.

A. Industrial field of application B0 Overview of the invention C9 Prior art [Figures 14 and 15] D1 Problems to be solved by the invention [Figures 14 and 15
[Figure] Means F for solving the E0 problem, Example a, Overview of vehicle-mounted revolving light, Base C, Globe C-11, Elastic material C-2, Slip C-3, Inner cover C-4, Connecting bolt C-5, outer cover d, unit stand e, and other G6 Effects of the invention (A. 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. A vehicle-mounted revolving light equipped with a unit base supporting a rotating unit, which facilitates attachment of the unit base to the glove, prevents rattling, and furthermore, prevents the glove from being scratched when the unit base is attached. The present invention aims to provide a new vehicle-mounted revolving light that prevents this from occurring.

(B. Summary of the Invention) The vehicle-mounted revolving light of the present invention has a structure that slides between a horizontal piece that projects inwardly from the side edge of the inner bottom of the globe and a lower surface of the horizontal piece that projects upwardly. A mounting rib is formed to form a space, an elastic material is attached to at least a portion of the lower surface of the horizontal piece facing the mounting rib, and a material with low frictional resistance is attached to the upper surface of the mounting rib. A sliding piece consisting of is attached, and both side edges of a unit stand supporting a rotating unit consisting of a light source and a reflecting mirror are slidably supported in the sliding space between the elastic material and the sliding piece, Since the sliding piece is provided on the upper surface of the mounting rib, when the unit stand is attached to the glove, the side edge of the unit stand will slide over the mounting rib, causing the unit stand to be attached to the glove. In addition, after the unit base is installed, the elastic material provided on the bottom surface of the horizontal piece presses against the side edges of the unit base, eliminating rattling. Since the part where the side edge of the unit stand touches is covered with an elastic material or a flap, the glove will not be damaged when the unit stand is attached.

(C, Prior Art) [Fig. 14, Fig. 15] Conventionally, in-vehicle revolving lights mounted on the roof of vehicles such as automobiles,
There is a type a as shown in FIG.

b is a base fixed to the roof of a car, etc.; C is a globe fixed to the base; d is a unit base detachably attached to the globe C; a light bulb is mounted on the unit base; A rotating unit e consisting of a mirror and a reflector is supported.

f is an outer cover that closes the outer opening of the glove C.

g and g are horizontal pieces protruding approximately horizontally from both sides of the inner bottom of the glove C; h and h are mounting ribs formed in a rising shape from the side edges of the inner bottom; A sliding space 111 is formed between the upper surfaces of h, h and the lower surfaces of the horizontal pieces g, g.

Thus, the unit stand d has its both side edges j1j inserted into the sliding spaces i, i, and the unit stand d is inserted into the globe C.
The outer cover f is attached to the glove C when the outer cover f is placed inside the glove C.

(D. Problems to be Solved by the Invention) [FIGS. 14 and 15] By the way, the above-mentioned conventional vehicle-mounted revolving light a has the following problems.

First, the side edges j of the unit stand d, the lower surface of j and the mounting rib h,
There is a line contact between the upper edge of h and the unit stand d has a considerable weight when the rotating unit e is supported thereon, so there is a problem that friction is large and it is difficult to mount the unit stand.

In addition, if the sliding spaces i, i are made larger in order to make it easier to install the unit stand d, looseness will occur between the sliding spaces i, i and the side edges j, j of the unit stand d, causing problems during driving. The unit stand d may wobble due to vibrations, etc., causing problems such as failure.

Furthermore, the inner bottom of the globe C is connected to the side edge J of the unit base d,
Since it is exposed with respect to j, when inserting the side edges j5 j of the unit stand d into the sliding space i51, the inner bottom of the glove C is exposed at the edge of the side edge j1 j of the unit stand d. I'm used to being hurt.

(E. Means for Solving the Problems) In order to solve the above-mentioned problems, the vehicle-mounted revolving light of the present invention has a horizontal piece that protrudes inwardly on the side edge of the inner bottom of the glove, and a horizontal piece that extends upwardly. a mounting rib is formed that protrudes toward the direction and forms a sliding space between it and the lower surface of the horizontal piece;
An elastic material is attached to at least the portion of the lower surface of the horizontal piece facing the mounting rib, a sliding piece made of a material with low frictional resistance is attached to the upper surface of the mounting rib, and a rotating member consisting of a light source and a reflecting mirror is attached. Both side edges of the unit stand supporting the unit are slidably supported in the sliding space between the elastic material and the sliding piece.

Therefore, according to the vehicle-mounted revolving light of the present invention, the sliding piece is provided on the upper surface of the mounting rib, so that the side edge of the unit stand slides over the mounting rib when the unit stand is attached to a glove. This makes it easier to attach the unit base to the glove.

Furthermore, after the unit base is installed, the elastic material provided on the lower surface of the horizontal piece presses against the side edges of the unit base, eliminating wobbling.

Furthermore, since the portions that the side edges of the unit base come into contact with when the unit base is attached are covered with an elastic material or a flap, the glove will not be damaged when the unit base is attached.

A unit stand is detachably attached to the glove and supports a rotating unit consisting of a light source, a reflector, etc., and a horizontal piece protrudes inward and an upwardly extending side edge of the inner bottom of the glove. A mounting rib is formed so that a sliding space is formed between the protruding horizontal piece and the lower surface of the horizontal piece, and an elastic material is attached to at least a portion of the lower surface of the horizontal piece that faces the mounting rib. A sliding piece made of a material with low frictional resistance is attached to the upper surface of the placement rib, and both side edges of the unit base can freely slide into a sliding space between the elastic material and the sliding piece.
