Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field 1jlj relates to a rotating warning device that is equipped with a rotating light and a reflector that reflects light from the rotating light.

(Naka) Prior Art Conventionally, a rotating warning device in which a rotating light is provided at the focal point of a concave mirror is well known (see Japanese Patent Publication No. 49-9280).

In this conventional device, the rotating light is fixed at the focal point of the concave mirror, and only one concave mirror is provided, so the diameter of the annular light beam rotating inside the concave mirror is always constant. Ta.

On the other hand, when using the rotary warning device, there is a desire to change the warning mode given to the viewer. For example, it is known that at night, the larger the diameter of the annular light beam is, the greater the warning effect will be, even if the brightness is low; on the other hand, during the day, even if the diameter of the annular light beam is small, the higher the brightness, the greater the warning effect will be. Moreover, it was desired that the warning mode be different at night and during the day.

Therefore, it would be possible to meet the above demand by creating separate rotary warning devices for nighttime and daytime use, but this would be too uneconomical.

09 Purpose of the Invention The present invention has been made in view of the drawbacks of the prior art. When using the same rotating lamp, the larger the diameter of the concave mirror, the larger the reflection area and the lower the brightness.
Focusing on the fact that the smaller the diameter, the narrower the reflection area and the higher the brightness, a single rotary warning device uses a plurality of concave mirrors to produce a plurality of warning modes.

B) Constituent Line of the Invention The present invention comprises a plurality of concave mirrors having focal points directly on the same plane; The light is 1°1) and f
jfl The rotating axis of the rotating light is characterized in that it coincides with the straight line.

0→ Embodiment FIGS. 1 and 2 are a front view and a partially sectional side view showing a first embodiment of the present invention. In these figures, (1) is a first annular parabolic mirror as a concave mirror, which is fixed to the top of a holding culm (3) that is movable up and down with respect to a base (2). . This first annular parabolic mirror (1
) is provided with a circular opening (4) in the center thereof, and a revolving light (5) is inserted through this opening (4). The revolving light (
5) A support arm (6) extends horizontally from the rear end, and this support arm (6) is fixed to the outer wall of the first annular parabolic mirror (1). Angle (7) K'x=4,
It is held slidably in the left and right direction.

(8) is a set screw that fixes the support arm (6) to the angle (7).

(9) l-i: A second annular parabolic mirror extending further forward from the front edge (outer edge) of the first annular parabolic mirror (1), its focal point (F2) t /i, a straight line (L) extending horizontally from the focal point (Fl) of the first annular parabolic mirror (1);
), J:.

The rotating light (5) has one rotating reflector (10).
It is of the type that rotates around the ball (11), but ■
There may be a type in which a pair of rotating reflecting mirrors rotates around the bulb, or a so-called sealed beam type in which the bulb and reflecting mirror rotate as one.

Note that the rotational axis of the rotating reflector (10) is the same as that of the first
It coincides with the straight line (L) connecting the focal point (Fl) of the annular parabolic mirror (1) and the focal point (F2) of the second annular parabolic mirror (9).

Now, the light bulb (11) of the rotating light (5) shown by the solid line in Figure 2
is located at the focal point (Fl) of the first annular parabolic mirror (1), so the light rays emitted from this light bulb (11) are located at the focal point (Fl) of the first annular parabolic mirror (1). The light is irradiated in the direction of the solid arrow while rotating the reflective surface. In addition, the rotating light (5) moves forward (to the left) together with the support arm (6), and the light bulb (11
) is located at the focal point (F2) of the second annular parabolic mirror (9) (the position indicated by the two-dot chain line), the light rays emitted from the light bulb (11) are directed to the second annular parabolic mirror (9). The light is irradiated in the direction of the chain arrow while rotating the reflecting surface of the object mirror (9).

Therefore, when the rotating light (5) is located in the solid line position, a viewer who is positioned forward can see a high-intensity but small-diameter annular light beam, and when it is in the chain line position, the viewer can see a low-intensity, but small-diameter circular light beam. A circular ray with a large diameter can be seen.

In this embodiment, the annular parabolic mirrors (1) and (9) are stacked in two stages, but it is also possible to stack them in three or four stages.

A plurality of through holes may be formed in the annular parabolic mirror (1) (9) so as to reduce the wind pressure caused by bending.

FIG. 3 is a partially sectional side view showing a second embodiment of the invention. In this figure, the rotating reflector and light bulb of the rotating light have the same structure as in the first embodiment (the same applies to the third and subsequent embodiments), so illustration thereof is omitted. Also,
Since the redoubt and the base are also of the same structure as in the first embodiment, the same reference numerals will be used and the explanation will be omitted.

In this figure, ('12) is a first annular parabolic mirror as a concave mirror, which is integrally formed on the back side with a second annular parabolic mirror (]3) having the same shape and dimensions. It is connected. In addition, the rotating light (14) has light emitting heads (16) (17) formed on the left and right sides of the base (15), and the light emitting head (16) on the left side is connected to the first annular parabolic mirror (12). Located at A, the right light emitting head (17) is configured to be located within the second annular parabolic mirror (13).

The base (15) of the rotating light (14) is made up of a bicyclic parabolic mirror (1
2) It is inserted into the inside of the cylindrical body (18) formed at the connection part of (18) so as to be slidable in the horizontal direction, and
9) Fixed at (20).

Therefore, as shown in the figure, when the rotating light (14) is unevenly distributed to the left, the annular light beam emitted from the first annular parabolic mirror (12) has a large diameter and low brightness. Therefore, the annular light beam emitted from the second annular parabolic mirror (13) has a small diameter and high brightness.

Therefore, during the day when high brightness is required, the light bulb and rotating reflector in the head (17) on the right side of the rotating light (14) are operated.
At night when a large-diameter annular beam is required, the left side of the head (1
6) The light bulb and rotating reflector in the interior may be operated, or the rotating light (14) may be unevenly distributed to the right.

In addition, in this embodiment, only one annular parabolic mirror (12) and (18) are provided, but it is not possible to stack two or three layers as in the first embodiment. The objects may be arranged in such a way that they are facing each other.

Moreover, a spherical mirror may be used instead of the annular parabolic mirrors (12) and (13).

FIG. 4 is a sectional view showing essential parts of a third embodiment of the present invention. In this figure, since there is no difference in the base from the previous embodiment, illustration thereof is omitted.

In this embodiment, a first annular parabolic mirror (21) with a small diameter and a second annular parabolic mirror (22) with a large diameter are provided so that their reflecting surfaces face away from each other. 1 annular parabolic mirror (
21) and the second annular parabolic mirror (22
) are integrally connected. (23
) (24) l-1: A rotating light (26) is supported by a flange arranged around an opening (25) formed in the center of the first annular parabolic mirror (21). Support rods (27) and (28) are fixedly provided for this purpose. The support rod (27
) (28), sliders (29, 80) are slidably loosely fitted into the sliders (29, 80), and the base body (31) of the revolving lamp (26) is fixedly mounted on the sliders (29, 80).

Therefore, if the rotating light (26) is moved to the right along the support rods (27) (28), the light rays emitted from the rotating light (26) will be directed to the first annular radiator. It is irradiated to the right (in the direction of the solid line arrow) while rotating within the object mirror (21). Also,
If the rotating light (26) is moved to the left, the rotating light (26)
The light beam emitted from the second annular parabolic mirror (22
) to radiate to the left (in the direction of the arrow) while rotating within the circle.

Therefore, the viewer on the right can recognize a circular light beam with high brightness but a small diameter, and the viewer on the left can recognize a circular light beam with low brightness but a large diameter.

FIG. 5 is a sectional view showing essential parts of a fourth embodiment of the present invention. The structure of the concave mirror of this embodiment is the same as that of the first embodiment, so the same reference numerals are given and the explanation will be omitted.

In this figure, (32) l-1: A motor with a reduction gear provided behind the first annular parabolic mirror (1), and is fixed to a base (not shown). This motor (32
) has a disk (34) fixed to the rotating shaft (33)K, and near the edge of this disk (34) is a connecting rod (
'85) is rotatably engaged at one end.

Further, the other end of the connector cron (35) in 11f is swingably engaged with the rear end of the revolving lamp (36).

9) (40) is a support rod, (41) and (42) are sliders.

Thus, while rotating the motor (32), the rotating light (3) is turned on.
When 6) is operated, the light beam emitted from the rotating light (36) rotates while reciprocating between the large-diameter annular parabolic mirror (9) and the seven small-diameter annular parabolic mirrors (1). become. Therefore,
By appropriately selecting the rotation speed of the rotating light (36) and the rotation speed of the disc (34), the observer in front can see double annular light beams or petal-shaped light beams. (!:become.

(F) Effects of the Invention In the present invention, a rotating light is movably provided between a plurality of concave mirrors and the focal points of these concave mirrors, so that by simply changing one side of the rotating light, an annular beam of light can be generated. Diameter and brightness can be changed. Therefore, two or more types of warning modes can be realized with one rotating warning device, and there is no need for a separate rotating warning device each time the warning mode changes as in the past, which is economical. be.

By moving the rotating illusion back and forth between the focal points of the concave mirror, we can create a rotating warning system with larger changes and a higher warning effect.
