Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an evacuation guidance device installed in a building.

[0002]

[Prior art]

 Evacuation exit guide light as an evacuation guidance device for safely guiding patients, guests, guests, spectators, employees, etc. to emergency exits in the event of a fire or other disaster in buildings such as hospitals, hotels, cinemas, office buildings, etc. There are known indoor and corridor guide lights, stairway guide lights, passenger guide lights, and guide signs. However, these guide lights and signs are merely green lights or signs that only indicate the presence of an evacuation passage or doorway, making them difficult to notice in times of confusion, especially if smoke is generated by the fire. It was sometimes invisible and was not always sufficient as an evacuation guidance device. Guidance devices using voice are also known, but it has been difficult to accurately determine the direction of voice generation.

[0003]

[Problems to be solved by the invention]

 The problem of this invention is to provide an evacuation guidance device that can be easily noticed even in the event of confusion due to a disaster and that can easily guide the evacuation direction even in smoke.

[0004]

[Means for Solving the Problems]

 The evacuation guidance system of the present invention has a rectangular parallelepiped box-shaped case with an opening at the front, a translucent sign panel for evacuation guidance attached to the front opening, and an illumination light inside. , A laser light emitting device is installed in a box-shaped case, laser light is emitted from the laser light emitting device in the event of a disaster, and circles, ellipses, straight lines, and arrows are applied to the floor, ceiling, or wall of the room where the evacuation guidance device is installed. It is characterized by drawing arbitrary figures such as.

[0005] Because laser light has strong directivity and high brightness, its optical path is visible even in smoke. In addition, the laser beam moves, and the spot that hits the floor, ceiling, or wall surface draws a figure such as a circle, ellipse, straight line, or arrow, and the laser beam travels indoors from the laser emitting device to the floor, ceiling, or wall surface. This moving laser beam indicates its firing position to draw a spreading fan-shaped plane or conical surface.The firing position is illuminated by a sign panel of the evacuation guidance device with an illumination lamp, so the evacuation direction is clear. . The above figure may be either a contour alone or a shape in which the inside of the contour is filled. In an emergency, voice guidance is also provided. If the laser light emitter is, for example, green, it is more effective if the voice prompts the user to evacuate in accordance with the green light without panic. .

[0006] The box-shaped case of the evacuation guidance device is formed in a horizontally long rectangular parallelepiped as in the related art, and the laser light emitting device is generally formed in an elongated rod shape. It is preferable to mount in parallel in the box-shaped case. Then, the laser light emitted from one end is reflected by the first and second reflectors provided in the box-shaped case in order and led out from the front of the evacuation guidance device, and the laser light is drawn in a circle. In this case, a circle or an ellipse is drawn on the ceiling, floor, wall, etc. with a spot of laser light, the diameter of which increases at a location far from the laser light-emitting device, and the second reflector has the smallest point-like shape. become. Note that, in order to cause the laser beam to draw a circle, one end of an elongated laser light emitting device may be vibrated in a circle to draw a minute circle, or a minute vibration may be given to each of the first and second reflectors. The movement may be combined to cause the laser light exiting the second reflector to draw a circle.

According to the third aspect of the present invention, it is possible to cause the laser light emitted from the reflector to draw a substantially horizontal straight line by the horizontal swing of the reflector. In this case, the laser beam is projected on the wall adjacent to the wall where the evacuation guidance device is installed, so that a horizontal straight line is drawn on this wall, and this straight line is run toward the corner that intersects with the installation wall. Can be made.

Further, as set forth in claim 4, the laser light emitted from the laser light emitting device is led out directly from the side surface of the box-shaped case, and substantially horizontal to the laser light by the horizontal swing of one end of the laser light emitting device. Can draw a simple straight line. In this case, by projecting the above-mentioned laser beam on the wall surface where the evacuation guidance device is installed, it is possible to draw a horizontal straight line on this wall surface and run this straight line toward the evacuation guidance device.

[0009]

[Embodiment of the invention]

 Embodiment 1 In FIG. 1, 1 is a front wall inside a building, 1a is an emergency exit for evacuation, 2 is an adjacent side wall, 3 is an indoor floor, 4 is a floor on a landing outside the emergency exit 1a, and 5 is an upper floor. The evacuation guidance device 10 is fixed to the front wall 1 above the emergency exit 1a.

As shown in FIG. 2, the evacuation guidance device 10 is provided with a frame-shaped edge cover 11 a at an opening of a rectangular box-shaped case 11 having a long side, and a green translucent sign panel 12 inside the frame. A human figure 12b is shown in a white part 12a at the center of the sign panel 12, indicating that there is an emergency exit 1a below. A round-bar-shaped fluorescent lamp 13 for illumination is horizontally mounted on the upper inside of the box-shaped case 11 so that the sign panel 12 is illuminated from the inside by the lighting thereof.

In the lower part of the inside of the box-shaped case 11, an elongated laser light emitting device 14 of a round bar shape is supported by left and right supports 15 and 16 in parallel with the fluorescent lamp 13 for illumination and at the tip (emission of laser light). The mouth 14a is attached to the right. However, the support 16 on the right side is a rotatable eccentric ring, and the tip 14a of the laser light emitting device 14 is inserted into the hole at the eccentric position, and the eccentric ring (support) 16 is rotated by a motor. A small circle is drawn on the tip 14a of the laser light emitting device 14.

As shown in FIGS. 2 and 3, the first reflector 17 faces the tip 14 a of the laser light emitting device 14 so that the laser light L emitted horizontally from the tip 14 a is reflected upward. The second reflector 18 is disposed above the second reflector 18 so as to reflect the reflected light forward (to the front of the drawing). On the other hand, a window hole (not shown) for allowing the reflected light to pass therethrough is formed in the edge cover 11a surrounding the sign panel 12 at a portion facing the second reflector 18. In addition, a guidance sound generation device 20 is provided above the second reflector 18 so as to guide by emitting a sound in an emergency.

Therefore, the laser light L emitted from the tip 14a of the laser light emitting device 14 spreads in a conical shape, passes through the first reflector 17, the second reflector 18, and the window of the edge cover 11a. Projected in front of 10, and draws a circle or ellipse on the projection surface. For example, when the direction of the reflected light is directed downward by adjusting the mounting angle of the second reflector 18, an ellipse E is drawn on the floor 3 in the room as shown in FIG. When the direction of the reflected light is horizontal, an ellipse E is drawn on the surface of the side wall 2. Alternatively, the laser light emitting device 14 may be fixed, and vibrations in different directions may be given to the first reflector 17 and the second reflector 18 so that a circle can be drawn by combining them. In this case, the mechanism is more complicated than when the tip 14a of the laser light emitting device 14 is vibrated, but energy for giving the vibration is saved.

Second Embodiment In FIG. 4, an evacuation guidance device 10 is fixed on a front wall 1 in the same manner as described above. However, in this embodiment, the laser light emitting device 14 is fixed, and one reflector 19 is installed so as to reflect the laser light L forward toward the tip 14a thereof and to be able to swing right and left. The left and right vibrations are given by the motor drive as shown by arrow A. Therefore, when the reflected light is directed toward the side wall 2 by adjusting the mounting angle of the reflector 19, the spot of the reflected light draws a substantially horizontal straight line on the side wall 2 and reciprocates within a predetermined range. By setting the speed at which the spot heads toward the front wall 1 to be slow and setting the speed in the opposite direction to be extremely high, the straight line of the spot heading toward the front wall 1 (see arrow B) is conspicuous. The evacuation direction can be indicated by the straight line movement drawn by the spot, making the moving spot invisible.

Embodiment 3 In FIG. 5, an emergency exit is present on the right end side of the side wall 2, and the evacuation guidance device 10 is fixed above the emergency exit. The laser light emitting device 14 is provided so as to be horizontally swingable with its tip 14a facing the left end of the side wall 2, and swings horizontally (see arrow A) by driving a motor. It is derived from ten aspects. In this case, the inclination angle of the laser light emitting device 14 with respect to the side wall 2 is adjusted, and the laser light L is swung horizontally toward the side wall 2 so that the laser light L is spotted on the side wall 2. Draw a straight line and reciprocate within a predetermined range. Then, by decreasing the rightward (see arrow B) speed of the spot and increasing the leftward speed, the straight line moving rightward can be conspicuous, and the evacuation direction can be indicated by a linear movement.
