Description

Emergency exit guidance device {Emergency Guide Display Device}

The present invention relates to an emergency exit guidance display device, and more specifically, to display a clear guidance indication on the ceiling surface and the floor at the same time so that the distress can easily find the emergency exit in case of power failure, fire, etc. in the building. An emergency exit induction display device that can be.

In general, the emergency light for guiding the distress to the emergency exit is provided at the walls of the corridors and stairs in the building. However, since these emergency lights are installed at intervals in the building, the distressed person in a state of embarrassment in an emergency does not find the emergency lights properly and may not go to the emergency exit. In addition, such emergency light is usually covered with a translucent plastic case in which the induction mark is drawn on the fluorescent lamp, the light intensity is weak, it is more difficult for the distress to check the emergency light if the smoke is filled in the building during the fire.

Therefore, conventionally, as disclosed in Korean Utility Model Publication No. 20-0213997, the light generating unit 23 configured to operate in an emergency is installed on the upper part of the wall in the building and on the upper part of the emergency exit, so that the light having an illuminance of 1300 lux or more. For example, the laser beam is irradiated at least 8 times / min so that the distress person can check the position of the emergency exit through the direction of the laser beam (see FIG. 1).

However, such a conventional emergency exit guidance display device causes the laser light to appear in a straight line in the space in the upper part of the building, so that the laser light is connected in a straight line between the light generating units provided on the upper part of the emergency exit and the upper wall. Therefore, it is not clear which direction of the laser beam which is a straight line is the direction which goes to an emergency exit. Therefore, in the conventional emergency exit guidance display device, there is a problem that the distressed person in a state of embarrassment often wanders without finding the emergency exit accurately in a short time.

In particular, when the smoke is filled in the building during the fire, hot smoke is located in the upper floor in the space in the building, oxygen is located in the lower floor in the space in the building, so the distressed person crawls on the floor to secure oxygen. However, in the conventional emergency exit display device, since the induction display is displayed only in the upper space of the building, there is a problem that the distress who crawls on the floor of the building cannot check the induction display.

In addition, in the conventional emergency exit guidance display device, since the laser beam is irradiated with one straight line, when the laser beam is obscured by an obstacle in an emergency such as a fire in a building, there is a problem that the distress cannot confirm the emergency exit direction.

An object of the present invention is to solve the above problems, can be displayed on the ceiling surface and the floor at the same time the clear indication of the direction so that the distress can easily find the emergency exit in case of power failure, fire, etc. in the building. The present invention provides an emergency exit guidance display.

The contact tip 61 of the automotive circuit breaker 60 is in contact with the conductive surface 31a. The contact tip 61 of the automobile breaker 60 is in contact with the conductive surface 31a normally. However, when the breaker 60 detects that the distribution of AC current / voltage is interrupted in an emergency such as a power failure or a fire, the automotive breaker 60 pulls the contact tip 61 backward to separate it from the conductive surface 31a. Therefore, the light generator 30 is smoothly rotated without being disturbed when it is rotated by the rotation driving unit 40 as described below.

In addition, a bearing 37 is formed around the center hole 32 at the other end of the light generating unit main body 31.

In addition, the support shaft 15a of the fixing knob 15 passes through the support hole 12 of the support 10, and the threaded portion 15b in the middle thereof is a screw in the boss 21 of the upper case 20a.

The charger 50 is usually connected to an AC current / voltage switchgear to charge the first and motor batteries 36 and 44. Although not shown, a well-known switch unit made of a voltageless relay or the like is electrically connected between the laser drive unit 34 and the laser battery 36 and between the motor unit 41 and the motor battery. The laser drive unit 34 and the motor unit 41 are controlled to " on " by detecting that the distribution of AC current / voltage is interrupted in an emergency.

The operation of the emergency exit guidance display device of the present invention configured as described above will be described with reference to FIGS. 4 and 5. 4 is a view showing a state in which the laser light is irradiated to the ceiling and the floor of the building from the emergency exit guidance display device of the present invention attached to the ceiling of the building, Figure 5 is the emergency exit guidance display of the present invention in place in the building It is a figure which shows that it is installed and a judo display.

In the event of a power outage, fire, or the like in the building, when the current breaker or the like of the switchboard is "off" by the disaster prevention system of the building, the current / voltage supplied to the emergency exit guidance display device 1 is "off" controlled. Next, the switch unit detects that the current / voltage supplied from the distribution line to the charger 50 is controlled to be “off”, and thus, the laser driver 34 and the motor unit 41 from the first and motor batteries 36 and 44 are controlled. The predetermined current / voltage supplied to each is controlled to " on ". Next, when a predetermined current / voltage is supplied from the laser battery 36 and the laser driver 34 is driven, the laser light is irradiated from the laser 33. Next, the laser beam is condensed by the condensing lens 35 into the projection holes 25a and 25b.

On the other hand, when a predetermined current / voltage is supplied from the motor battery 44 and the motor part 41 is driven, the light generating part in which the key is coupled to the drive shaft 43a of the gear part 43 connected to the motor part 41. 30 is driven to rotate in a predetermined rotational direction. As a result, the laser beam irradiated from the rotating light generator 30 is changed into an arrow while passing through the through holes 25a and 25b arranged in a matrix form of the case 20, and the predetermined distance is fixed to the ceiling surface and the floor surface. The light emitting holes 25a of the upper case 20a and the light emitting holes 25b of the lower case 20b are formed in opposite directions to each other, and thus the upper case 20a The laser light passing through the light transmitting hole 25a of the s) is projected in the form of a dotted line in a plurality of rows on the ceiling surface with the arrow B facing in the emergency exit direction, and the laser light passing through the light emitting hole 25b of the lower case 20b is also used. Arrow B is projected in the form of a dotted line in a plurality of rows on the bottom face in the direction of the emergency exit.

Here, when the light generator 30 is slowly rotated, the arrow is moved in the rotation direction by the plurality of projection holes 25a and 25b spaced apart at predetermined intervals in the circumferential direction from the case 20. However, the light generating unit 30 is configured to rotate only in one direction, and the direction of the arrows of the projection hole 25a of the upper case 20a and the projection hole 25b of the lower case 20b are opposite to each other. Since it is formed in the direction, for example, when the light generating unit 30 is slowly rotated in the direction of the arrow of the upper case 20a, the arrow projected on the ceiling surface appears to move in the emergency exit direction, but is projected on the bottom surface. The arrow will appear to move in the direction opposite to the exit direction.

Therefore, in order to prevent the arrow projected on either the ceiling surface or the bottom surface from moving in the direction opposite to the emergency exit direction, the rotational speed of the light generating portion 30 is controlled by the laser beams through the projection holes 25a and 25b. The interruption of the light must be rotated at a high speed that is not recognized by the human eye, that is, 8 times / second or more. The rotation speed of the light generator 30 is preferably 1,200-1,800 rpm.

In the present embodiment, three lasers are arranged in the lateral direction of the light generating body and only one laser is arranged in the circumferential direction of the light generating body. However, two or more lasers may be arranged in the circumferential direction of the light generating body. It may be. In this case, the rotation speed of the light generating unit can be reduced by increasing the number of lasers.

In the present embodiment, the wires connecting the first and motor batteries, the motor unit, the laser drive unit, and the automatic breaker are not shown in the drawings for clarity of the drawings. Since the wires are conventional, the technical configuration related to the wires is sufficiently understood. Could be.

According to the emergency exit guidance display device of the present invention as described above, the building by rotating the light generating unit at a high speed in the cylindrical case consisting of the upper case and the lower case of the semi-cylindrical array of a plurality of arrow-shaped projection holes toward the exit direction It is possible to simultaneously project a plurality of rows of arrows in the form of dotted lines in the direction of the emergency exit on the ceiling surface and the bottom surface of the plane.

In particular, the emergency exit guidance display device of the present invention because the arrow clearly showing the emergency exit direction is projected on the ceiling surface and the bottom surface, so that the distressed distress can find the emergency exit accurately in a short time without wandering without finding the emergency exit direction.

In addition, the emergency exit guidance device of the present invention, since the arrow is projected on the ceiling surface and the bottom surface at the same time, even if the evacuator escapes while the evacuator crawls on the floor to secure the oxygen when the fire is filled in the room during the fire It is possible to easily recognize the direction of.

In addition, since the arrows are projected on the ceiling surface and the floor surface in a plurality of rows in the emergency exit guidance display device of the present invention, even if one row of arrows is blocked on the ceiling surface or the floor surface by an obstacle during an emergency such as a fire in a building, The row of arrows makes it easy for the distress to see the exit direction.

In addition, since the emergency exit induction display device of the present invention is driven by a battery charged by a charger, the emergency exit induction display apparatus is reliably operated even if the power supply is interrupted from the power distribution line in an emergency such as a power failure or a fire.
