Embodiments Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view showing the basic configuration of an emergency evacuation guidance device according to the present invention. In the figure, reference numeral 11 is a laser oscillator that oscillates a laser beam B. The laser oscillating device 11 is arranged so as to oscillate the laser beam B toward a direction for emergency evacuation, for example, an emergency evacuation exit (emergency exit) 12. The laser oscillation device 11 is preferably arranged at a relatively high position, for example, a position above the wall surface W so that it can be easily seen by an evacuated person.

Further, the laser oscillation device 11 has a built-in operating power source so that it can be operated even when the power supply to the building is stopped.

Reference numerals 13 and 14 are anomaly detection devices that detect anomalies occurring inside the building and generate anomaly detection signals, for example, smoke detectors 13 installed on the ceiling surface, earthquakes installed on the wall surface or floor surface. A sensor 14 or the like is used. In addition to this, a temperature detection sensor, a gas detection sensor, etc. can be used in combination.

These abnormality detection devices 13 and 14 are connected to the control device 15, respectively, and an abnormality detection signal is sent to the control device 15. The laser oscillation device 11 is also connected to the control device 15, and an operation command signal based on the abnormality detection signal is input from the control device 15.

The control device 15 is further equipped with a general push button type alarm.
16 is connected so that an abnormality detection signal can be sent to the control device 15 by a human operation.

Next, the operation of this embodiment having such a configuration will be described.

When an abnormality such as a fire occurs in a building, the abnormality detection devices 13 and 14 first detect the abnormality, and an abnormality detection signal is sent to the control device 15. Controller 15 receiving this signal
Sends an operation command signal to the laser oscillator 11, and the laser oscillator 11 automatically operates. The laser beam B is oscillated and is directed in the direction of emergency evacuation.

A person who wants to make an emergency evacuation can know the evacuation route by looking at the pointing direction of the laser beam B. In order to clearly show the evacuation route, it is effective to expand the width of the oscillated laser beam B in the evacuation direction, for example. It is also effective to make an emergency broadcast with the content "Please evacuate along the laser beam B."

Since the laser beam B has the property of proceeding straight without attenuating the light power, it can reach a long distance even if smoke is generated, and the evacuation route is not lost. In addition, the light traces of the laser beam are reflected by smoke particles, which can more clearly indicate the evacuation route.

As described above, according to this embodiment, it is possible to safely guide people to the emergency exit even in a building where smoke is trapped.

In the present embodiment, the control device 15 is separately provided, but the control device 15 can be integrated into the laser oscillation device 11.

FIG. 2 is a schematic perspective view showing another embodiment of the present invention and shows an example in the case where there is an obstacle or the like in the middle of the emergency evacuation route.

For example, if there is an obstacle A in the middle of the evacuation route or there is a protrusion C at the position where the laser oscillator 11 is to be installed,
When the laser beam B from the laser oscillator 11 cannot be oscillated directly toward the emergency exit 12, the optical path of the laser beam B can be changed by using the optical scanner 18 so that the laser beam B can reach the target location. Is being done.

The optical scanner 18 includes a mirror that rotates repeatedly and a motor that rotates the mirror. The laser beam B can be incident on the mirror and reflected in a predetermined direction. Optical scanner
It is desirable that the 18 power sources (batteries) are built-in in case of a power failure.

The optical scanner 18 is arranged in the optical path of the laser beam B from the laser oscillator 11, and the rotation angle of the mirror of the optical scanner 18 is controlled so that the light beam reflected by the optical scanner 18 is directed toward the emergency exit 12. There is. The optical scanner 18 is electrically connected to the control device (not shown) together with the abnormality detection device and the laser oscillation device 11 as in the above-described embodiment.

Therefore, in the present embodiment, when an abnormality detection signal is issued by the abnormality detection device, the laser oscillator 11 is activated to oscillate the laser beam B, the optical scanner 18 is activated, and the mirror detects this laser beam B. Expand to a specified width and target location (eg emergency exit 12)
Point in the direction.

As a result, the optical path of the laser beam B can be changed, and even if there is an obstacle A in the middle of the optical path, the evacuation guidance laser beam B can be made easily visible and reach a predetermined destination. it can.

As a means for changing the optical path of the laser beam B, it is also possible to use an ordinary fixed mirror instead of the optical scanner 18. However, if the optical scanner 18 is used, the laser beam B having a small width of about 1 to 8 mm can be expanded to a width that is easily visible. Further, the mirror of the optical scanner 18 is manufactured with high accuracy on the surface, so that there is little light scattering and there is an effect that the reflection performance of the laser beam B is not deteriorated even if the surface is slightly soiled.

FIG. 3 is a schematic perspective view showing another embodiment of the present invention. This embodiment is applied when the evacuation route (for example, corridor) is curved.

A laser oscillating device 11 is arranged above the wall surface W so as to oscillate the laser beam B along the evacuation route. Further, an optical scanner 18 equipped with a rotating mirror and a small motor is arranged in the optical path of the laser beam B at the bend angle of the evacuation route, for example, the bend angle of the wall surface W, so as to direct the laser beam B in the evacuation direction. Has been done.
Also in this embodiment, similarly to the above-described embodiments, the laser oscillator 11, the abnormality detecting device and the optical scanner are used.
18 is electrically connected to a controller (not shown).

According to the present embodiment, the laser beam B from the laser oscillation device 11 is bent by the optical scanner 18 at each bending angle of the evacuation route along the evacuation route to reach the emergency exit 12. Therefore, the person who evacuates can surely reach the emergency exit 12 by moving along the optical path of the laser beam B.

Also in this embodiment, as a means for changing the optical path of the laser beam B, an ordinary fixed mirror can be used instead of the optical scanner 18.

FIG. 4 is a schematic perspective view showing another embodiment of the present invention. This embodiment is used, for example, to illuminate the green character display of "emergency exit" defined by the Fire Service Law.

In the present embodiment, an x-axis optical scanner 18a and a y-axis optical scanner 18b having mutually orthogonal rotation axes are arranged in the optical path of the laser beam B, and the laser beam B is x-rayed by vibrating the respective mirrors. The width of the beam can be obtained by shaking in the axial direction and the y-axis direction.

Thereby, it becomes possible to illuminate a predetermined area, and it becomes possible to clearly read the character information indicating the "emergency exit" even from a distance. This makes it easy to find the emergency exit, especially if there is smoke.

FIG. 5 shows an application example of the above-described embodiment having an x-axis optical scanner 18a and a y-axis optical scanner 18b. In this embodiment, the rotational frequency of the x-axis optical scanner 18a and the y-axis optical scanner 18b is controlled so that the character "emergency exit" 19 is drawn on the evacuation door D.

Further, by controlling the rotational frequency of the optical scanners 18a and 18b, it is possible to draw arbitrary character information. Also, in addition to the evacuation door, it is possible to draw text and graphic information on the wall surface, the smoke that is standing up, and the space.

By drawing out the character information in this way, it is possible to give a person who is evacuated more mentally and comfortably.

FIG. 6 is an explanatory view showing still another embodiment of the present invention. In this embodiment, by controlling the frequency of the optical scanner 18, the width of the laser beam B is expanded toward the evacuation direction, and the evacuation is performed in the band of light formed by the laser beam B. A wavy shape S indicating the direction, for example, a polygonal continuous pattern as shown in FIG. 6 is provided.

By providing such a wavy shape S, the evacuation direction can be more surely known.

FIG. 7 is a schematic perspective view showing another embodiment of the present invention. In this embodiment, the laser oscillator 11 is arranged near the emergency exit 12 which is an exit for emergency evacuation, and oscillates the laser beam B toward the inside of the building. An optical scanner 18 is arranged at a corner of the evacuation route so that the laser beam B oscillated from the laser oscillation device 11 reaches a deep part in the building.

According to the present embodiment, since the laser beam B is oscillated from the emergency exit side, the direction toward the emergency exit 12 side can be always shown no matter how thick smoke is trapped. That is, even if the laser beam B does not reach far due to insufficient light power of the laser beam B, the direction of the emergency exit 12, which is the most important direction, has a difference in the laser beam reach distance,
It will definitely be shown.

Moreover, since the width of the laser beam B is gradually narrowed toward the emergency exit 12, it is psychologically effective in pointing the escape direction. In addition, since the light source escapes in a strong direction, there is an effect of giving a psychological sense of security also in this sense.

FIG. 8 is an external perspective view showing the protective cover 21 of the optical scanner 18. The optical scanner 18 arranged in the middle of the evacuation route is easily damaged when an object collides with it. For this reason, the optical scanner 18 has a protective cover.
It should be covered by 21. This protective cover
As shown in FIG. 8, it is desirable that the notch 21a be provided at a portion corresponding to a path through which the laser beam B passes.

〔The invention's effect〕

As explained above, by oscillating a laser beam with excellent transparency in the direction of emergency evacuation or from the emergency exit side toward the inside of the building, it is possible to provide emergency evacuation guidance information without being obstructed by smoke or the like. You can Also,
By using the optical scanner together, the optical path of the laser beam can be changed, the laser beam can be used for multiple purposes, and the application range of the emergency evacuation guidance device can be expanded.

INDUSTRIAL APPLICABILITY The present invention, when installed in a building where many people gather, such as a department store, a hotel, an offhill building, and an underground mall, exerts an excellent effect as an auxiliary device for artificial emergency evacuation guidance when an abnormal situation occurs. .
