Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an oscillating lighting device for warning or the like.

<Prior Art> Conventionally, various types of lighting devices for warning have been developed, but a diffused type with a plurality of reflectors, a ball blinking type, or a blinking type with a structure in which a reflecting mirror is rotated. Met.

<Problems to be Solved by the Invention> In the above-mentioned diffuser type, a plurality of reflectors, preferably a large number of reflectors, must be arranged at positions suitable for light diffusion, which inevitably requires a lot of space. Further, since the above-mentioned blinking type is a warning by blinking itself, it is disliked that the warning by illumination is limited to a simple case, and a strong visual effect cannot be expected.

Therefore, in this invention, a unique swaying illumination effect as reflected light, which is not in the above-mentioned diffuser type or blinking type illuminating device, can be obtained, and a sufficient warning effect can be obtained even with a small space and a small number of light bulbs. Trying to provide.

<Means for Solving the Problems> In order to solve the above-mentioned problems, as a configuration of a swinging lighting device for warning, etc., a reflector placed behind the light bulb separately from the light bulb has a vertical axis as a center. In addition, a cam mechanism is provided between the drive mechanism from the motor and the reflector so that it can be tilted laterally within a required angle range of 180 degrees or less and can be vertically tilted within a required angle range about the horizontal axis. It is characterized in that the reflection illumination is swung by a combination of vertical and horizontal tilting of the reflector.

<Operation> In the swing type illumination device having the above-described configuration, the reflector is positioned behind the light bulb and separately from the light bulb, and the cam mechanism tilts in a lateral direction at a required angle about the vertical axis. , Since a tilt in the vertical direction of the required angle about the horizontal axis is given, these tilts in the vertical and horizontal directions are combined, and the reflected light from the light bulb is oscillated in the vertical and horizontal directions and reflected by one light bulb. Even if there is, a unique warning light can be given by various swings.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

1 to 4 show the outline of the whole device of the present invention. (1) is a casing, (2) is a lower fixed base plate, (3) is a pin for the fixed base plate (2). (4) shows the frame rotatably supported. This pin (4) is the center of the vertical axis.

Regarding each part of the frame (3), standing parts (32) (32) are erected on the left and right sides of the lower plate (31), and are substantially horizontal from the back part (33) crossed over the standing parts (32) (32). A connecting part (34) for starting is extended to the connecting part (34), and the connecting part (34) has a long groove (35) for a cam pin which will be described later and an end part (36) is formed upright.

Next, (5) is a reflector which is rotatably supported by pins (6) and (6) with respect to the left and right upright portions (32) and (32) of the frame (3). The pins (6) and (6) form a horizontal axis with respect to the reflection plate (5). In the case of the figure, the reflector (5) is integrally connected to the reflecting part (51) which is behind the bulb and which is curved when viewed from a plane, and the reflecting part (52) which is projected horizontally. , Fixed base plate
It is attached to the socket part (7) standing on the (2) side and is located separately from the light bulb (8). Further, the back (53) of the reflector (5) is provided with a claw (54) for receiving vertical or vertical tilting, and the reflector (5) is attached from the end (36) of the frame (3) to the spring (9). 5) is pulled upward.

(10) is a motor, and a cam mechanism (20) from this motor (10) through a drive mechanism (11) that is a combination of a pinion and a gear.
Is transmitted to.

The cam mechanism (20) will be described. The cam (21) and the lever (22) whose position is changed by touching the circumferential surface of the cam (21).
And a pin (24) eccentric from the cam shaft (29).
The pin (24) is the long groove provided in the connecting portion (34) of the frame (3).
The frame (3) is fitted in the (35) so that the frame (3) can be moved laterally in accordance with the rotation of the cam (21). The base (23) of the lever (22) is supported by a pin (27) so as to be freely rotatable on the base plate (1).

The base (23) of the lever (22) is further bent to form the other lever (25). This lever (25) is a reflector
The claw (54) on the back (53) of (5) can be moved, and functions to tilt the reflection plate (5) downward against the tensile force of the spring (9).

In the case of the above embodiment, with respect to the lateral movement of the reflection plate (5), the pin (24) which is eccentric by the rotation of the cam (21) is used.
By changing the position of, the frame (3) in which the long groove (35) is fitted in the pin (24) is moved vertically to the left or right around the pin (4) on the base plate (1). The lever (22), which comes into contact with the peripheral surface of the cam (21), is pivoted about the pin (24) on the base plate (1).
When the (23) rotates, the other lever (25) moves back and forth,
By moving the claw (54), the reflecting plate (5) can be tilted vertically and vertically about the horizontal axis by a required angle.

Such tilting of the reflector plate (5) vertically and horizontally at a required angle is combined, so that the reflected light from the light bulb (8) oscillates in various ways and functions as a warning light.

FIG. 5 is a detailed step-by-step description of the operation of the cam mechanism (20), the levers (22) and (25), and the frame (3) on the long groove (35) side.

(A) of this figure shows the movement of the cam (21) and lever (22) (25), and (b)
Is a reflector (5) formed by the lever (25) and the claw (54) on the reflector (5) side
(C) is the eccentric pin (24)
The horizontal direction of the reflector (5), that is, the degree of left-right tilting due to the movement of the frame (3) is shown in correspondence with each of the steps I to V, and will be described below.

First, in stage I, the reflector 5 is not tilted up and down, and is not tilted left or right.

Next, when the cam rotates to the stage II, the lever (25) moves forward, the reflector (5) is pulled up by the spring (9),
While facing upward, the pin (24) tilts the frame (3) to the right when viewed from the plane shown in the drawing, and the reflector (5) also tilts.

Therefore, the light reflected by the light bulb (8) moves diagonally leftward from the base point of stage I.

When the cam is sequentially rotated to reach the stage III, the lever (25) moves rearward again, and the reflector (5) tilts contrary to the tensile force of the spring (9) to return to the original state of the stage I. The frame (3) is slightly tilted from the stage II by the pin (24), and the reflector (5) is also tilted. Therefore, the reflected light from the bulb (8) is II
Although it shifts downward from the stage and tilts slightly to the left, overall, it tilts slightly to the left and makes a large shift downward.

Furthermore, the cam rotates to the IV stage, but the lever (25) remains in the same position as the III stage, and the pin (24) causes the frame (3) to move.
Is in the opposite direction, that is, tilts to the left when viewed from the plane shown, and the reflector plate
(5) also tilts. Therefore, the light reflected by the light bulb (8) moves straight from the stage III state to the left.

Then, when the cam is rotated to the V stage, the lever (25) moves forward, the reflector (5) is pulled up by the spring (9), becomes upward, and the frame (3) is pulled by the pin (24).
However, a slight tilt is added from the IV stage, and the reflector (5) also tilts. Therefore, the reflected light from the light bulb (8) shifts upward from the IV stage and slightly tilts to the right, but when viewed as a whole, it slightly shifts to the right and largely shifts upward.

Then, from the IV stage to the return to the I stage, this movement cam-rotates and the lever (25) again moves backward, and the reflector plate
(5) tilts in the opposite direction to the tensile force of the spring (9), returns to a state where there is almost no tilt, and the pin (24) causes the frame to
(3) tilts from the V stage to the right as viewed from the plan view shown, and the reflector (5) also tilts to return to a state without tilt.

Therefore, from the V stage to the I stage, the light reflected by the light bulb (8) moves diagonally downward to the left.

It will repeat the cycle as described above,
The movement of the reflected light in one cycle is as follows:
This will be accompanied by a synthesized swing as shown in FIG.

In addition, in the case of FIG. 7 and FIG. 8 illustrated as modified examples of the implementation, a hole (26) is formed in the cam (21) and the hole (2
The lever pin (28) is fitted in (6) so that it can move along the hole (26) so that the other lever (25) connected to the lever pin (28) can move the claw (54) back and forth. The structure is shown. In addition, various known structures can be adopted as the cam mechanism for inclining the reflecting plate (5) vertically and vertically as well as horizontally and horizontally.

As the reflecting plate, in addition to a highly reflective plate-like member, various known ones such as those having a mirror surface structure can be adopted. Further, as for the light bulb, the reflected light may be combined by using a plurality of light bulbs as in the above embodiment.

<Advantages of the Invention> As described above, in the swing type lighting device according to the present invention, since the reflector can be tilted in the lateral direction at the required angle and can be tilted in the longitudinal direction at the required angle, the tilting of these devices can be performed. It is possible to give the reflected light a shake due to the composition of, and to emit a shake reflected light that makes a unique and complicated movement,
It is possible to emit a variety of reflected light for warning even with a small number of light bulbs.

The reflected light for warning obtained by this invention is visually recognized as an irregular flash of light peculiar to the person to be warned, and therefore the alertness is higher than that of the conventional lighting device.

Therefore, various kinds of reflected light for warning can be obtained in a small space, and a highly practical effect can be obtained as an illuminating device such as a patrol car. Further, when it is mounted on a vehicle and used, it is more effective if it is used in combination with another diffuser type warning light.

Moreover, since the reflector is tilted over the required angle range of 180 degrees or less in the lateral direction, it is possible to intensively give the warning light in a certain direction. for that reason,
Compared to a structure that emits light over 360 degrees around such as a rotating lamp, the warning effect per unit area can be significantly enhanced in the direction in which the warning light is desired to be given.
