Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a rotating warning light that is equipped with a rotating light and a reflector that reflects light from the rotating light.

(B) Prior Art Conventionally, rotating warning lights in which a rotating light is provided in the center of a concave mirror so that its axis of rotation substantially coincides with the center line of the concave mirror have been manufactured and sold by the applicant. and is well known (for example, the Special Publication Act of 1973-
(See Publication No. 9280).

In such conventional rotating warning lights, the concave mirror is formed by press-molding a large metal disk with a press mold or by squeezing it with a spatula drawing device.

(c) Problems that the invention aims to solve As mentioned above, in the conventional technology, concave mirrors were formed by press forming or drawing with a spatula from a single metal disk, In order to manufacture concave mirrors, large press equipment and spatula drawing equipment are required, leading to higher prices and larger sizes of equipment.

(d) Means for solving the problem In the present invention, a holder is attached to the center of a concave mirror, and a rotating light is provided on the holder so that the axis of rotation approximately coincides with the center line of the concave mirror. In the rotating warning light, the concave mirror is mounted radially between a frame provided around the rotating light so as to surround the rotating shaft of the rotating light, and the frame and the holding base. This rotating warning light is characterized by comprising a plurality of reflectors.

(e) Effect In the present invention, the concave mirror is mounted radially between a frame provided around the rotating light so as to surround the rotating shaft of the rotating light, and the frame and the holding base. Since the concave mirror is composed of a plurality of reflecting plates, a concave mirror can be constructed by assembling the respective reflecting plates.

(f) Embodiment FIGS. 1 to 3 show a first embodiment, in which FIG. 1 is a front view, FIG. 2 is a side view, and FIG. 3 is a partial front view. 4 and 5 show a second embodiment, with FIG. 4 being a front view and FIG. 5 being a partial front view.

In the first embodiment, reference numeral 1 denotes a support shaft vertically erected on the ground or the like, and is fixed to the ground or the like with a tripod (not shown). One side wall of a holding table 2 having a hexagonal shape and a U-shaped cross section is welded to the upper end of the first support shaft 1. A rotating light is fixed to the inner bottom of the holding base 2 with screws in such a posture that its axis of rotation extends in the horizontal direction. This revolving light 3
is a well-known type in which a reflector revolves around the light bulb by a motor built into the base.

A hexagonal frame 4 is provided around the holding base 2 so as to surround the rotation axis of the rotating light 3,
Between the mutually opposing sides of the frame 4 and the holding base 2,
Six trapezoidal reflecting plates 5 as shown in FIG. 3 are curved and mounted in a reflective manner to form a concave mirror 6.

Note that spaces 7 through which air can pass are formed between the reflective plates 5 disposed adjacent to each other, and these spaces 7 serve as ventilation holes and light transmission holes. .

Next, a second embodiment will be explained. This second
In the embodiment, the arc portion of the frame 4 and the holding body 2 are formed by connecting four straight lines and four arcs alternately.
5, four fan-shaped reflecting plates 5 as shown in FIG.

(g) Effects of the invention In the invention, the concave mirror is mounted radially between a frame provided around the rotating light so as to surround the rotation axis of the rotating light, and the frame and the holding base. Since it is composed of a plurality of reflecting plates, a concave mirror can be constructed by assembling each reflecting plate, and there is no need for large press equipment or spatula diaphragm equipment, which is expensive and large. Large rotating warning lights can be manufactured without the need for manufacturing equipment.

In addition, if a space is formed between each reflector plate through which air can pass, the wind blown in from the front of the concave mirror will flow out of the space to the rear, and will not be subjected to strong wind pressure from the front of the concave mirror. The number of fall accidents due to this will be reduced.
