Is detected by magnetic sensors 17a, 17b provided in the electric cart section 9.

  Two metal rails (not shown) are installed on the floors of the private rooms 2a to 2l so as to extend along both sides of the guide wire 32 for the private room, and a bed is placed on each rail (not shown). The wheels (front wheels 11a and 11b, rear wheels 12a and 12b) of the device 8 (electric cart portion 9) are moved. As a result, the traveling surfaces of the wheels (front wheels 11a and 11b, rear wheels 12a and 12b) are reliably maintained even in a fire. Moreover, the isolation wall and outer wall etc. which partition between each private room 2a-2l of this structure (special elderly nursing home) 1 are also formed with the fireproof material.

  Next, the evacuation operation of the bed apparatus 8 by the emergency evacuation system at the time of fire of the above-described structure (special nursing home) 1 will be described.

  When a fire occurs in the structure (special elderly nursing home) 1, if any fire alarm 6 in the structure (special nursing home) 1 detects a fire and issues an alarm, the fire alarm 6 A fire detection signal is input to the fire alarm control panel 7 via a signal line (not shown).

  When a fire detection signal is input from the fire alarm 6, the fire alarm control panel 7 outputs a door opening signal to each door opening / closing drive unit (not illustrated) via a signal line (not illustrated). By driving each door opening / closing drive unit (not shown), the respective entrance doors 21 of the closed private chambers 2a to 2l and the respective entrance / exit doors 38, 39 of the passages 30, 31 are automatically opened simultaneously.

  Furthermore, when a fire detection signal is input from the fire alarm 6 to the fire alarm control panel 7, a radio signal is transmitted from the antenna 7a to the antenna 19a of the electric cart control unit 19 of each bed apparatus 8 (electric cart unit 9). It is transmitted to the wireless receiver 19b).

  When the electric cart control unit 19 receives a radio signal, it first outputs a drive signal to the flameproof sheet drive unit 26. The winding mechanism (not shown) is driven by the driving of the flameproof sheet drive unit 26, and the wound flameproof sheet 25 is moved forward on the frame-shaped frame 24 (of the care recipient C) as shown in FIG. It is extended to the head side and covers the upper space of the electric bed 22. Thereby, since the upper part of the care recipient C sleeping on the electric bed 22 can be covered with the flameproof sheet 25, it is possible to prevent sparks and the like from falling on the care recipient C during evacuation.

  Then, after the upper space of the electric bed 22 is covered with the flameproof sheet 25, the electric cart control unit 19 sends a drive signal to a drive motor (not shown) of the second traveling drive unit 14 based on the received radio signal. And a drive motor (not shown) is rotationally driven. At this time, the electric cart controller 19 of each bed apparatus 8 (electric cart section 9) of the private rooms 2a to 2l is connected to the bed apparatus (in FIG. The drive motor (not shown) of the second travel drive unit 14 is set to rotate at predetermined time intervals (for example, several seconds to several tens of seconds) in order from the bed devices 8 of 2a and 2g.

  That is, for each bed apparatus 8 of the private rooms 2a to 2l, by traveling (moving) at a predetermined time interval, for example, at a speed of about 2 to 4 km per hour from the private room (the private rooms 2a and 2g) close to the escape path 35, Each bed apparatus 8 of the private rooms 2a to 2l can be evacuated orderly and smoothly. The traveling speed of the bed apparatus 8 can be set in advance to an appropriate speed depending on the number of bed apparatuses 8 and the structure of the traveling route.

  Then, as shown in FIG. 6, first, the drive motor (not shown) of the second traveling drive unit 14 of each bed apparatus 8 of the private chambers 2a and 2g is driven, and each bed apparatus 8 is moved to the entrance door 21 side. When the vehicle starts traveling, the magnetic field generated from the guide wire 32 for the single room is detected by the magnetic sensor 17a at the front (front wheels 11a, 11b side). Then, the electric cart control unit 19 controls the first steering unit 15 based on this detection signal so that each bed apparatus 8 travels to the side of the passages 30 and 31 along the private room guide line 32 to control the front wheels. Steer 11a, 11b.

  Then, as shown in FIG. 7, each bed apparatus 8 moved from the private chambers 2a and 2g to the passages 30 and 31 through the entrance door 21 is similarly guided by the magnetic sensor 17a to the passage guide lines 33 and 34 and the escape route guide lines. The magnetic field generated from 36 and 37 is detected. Then, the electric cart control unit 19 determines that each bed apparatus 8 passes through the passage guide lines 33 and 34 and the escape route guide lines 36 and 37 from the passages 30 and 31 based on the detection signal. The front wheels 11a and 11b are steered by controlling the first steering unit 15 so as to travel through the evacuation path 35.

  Then, as shown in FIG. 8, each bed apparatus 8 exiting from the individual rooms 2a to 2l evacuates from the passages 30 and 31 along the passage guide lines 33 and 34 and the escape route guide lines 36 and 37 at predetermined intervals. Similarly, the vehicle travels (moves) to the evacuation site (not shown) ahead of the road 35. And since the guide wire is not embedded in the tip, a magnetic field is not detected. If the magnetic sensor 17a does not detect a magnetic field, the electric cart control unit 19 outputs a stop signal to the second traveling drive unit 14 so that the head bed device 8 automatically stops at an evacuation place (not shown). .

  When each bed apparatus 8 is continuously gathered at an evacuation site (not shown), one ultrasonic sensor (a rear-end collision prevention sensor) 18a provided on each bed apparatus 8 has approached the bed apparatus 8 ahead by a predetermined amount or more. Is detected, the electric cart control unit 19 outputs a stop signal to the second traveling drive unit 14 to stop the bed apparatus 8, thereby preventing a collision. Even when each bed apparatus 8 is traveling on the passages 30 and 31 and the evacuation path 35, when the ultrasonic sensor 18a provided in each bed apparatus 8 detects that the bed apparatus 8 approaches the front bed apparatus 8 or more, the electric cart The control unit 19 outputs a stop signal to the second travel drive unit 14 to temporarily stop the bed apparatus 8 and resumes travel after the approaching state is resolved.

  Thus, according to the emergency evacuation system at the time of fire in the present invention described above, when a fire occurs in the structure (special elderly nursing home) 1, based on the fire detection signal output from the fire alarm 6, After the entrance doors 21 and 38 and 39 of the passages 30 and 31 are automatically opened after the entrance doors 21 of the private rooms 2a to 2l and the care recipients of the private rooms 2a to 2l are lying on the upper side of each bed apparatus 8 After the seat 25 is automatically covered, each bed apparatus 8 is automatically run along the guide lines (individual guide lines 32, passage guide lines 33, 34, escape route guide lines 36, 37), It can be quickly moved to an evacuation site (not shown) outside the structure 1 in a short time.

  Therefore, even when the number of nurses on duty is small at night or the like, all the care recipients can be surely evacuated to the safe evacuation place with the bed apparatus 8 without relying on the nurses.

  Note that the above-described emergency evacuation system at the time of fire can generate the fire detection signal on a trial basis by manually operating the fire alarm control panel 7 during regular fire evacuation training. When a fire detection signal is generated on a trial basis, each of the entrance doors 21 of the private rooms 2a to 2l and the entrance doors 38 and 39 of the passages 30 and 31 are automatically opened in the same manner as at the time of the fire, and then the private rooms 2a to 2l. After the flame proof sheet 25 is automatically covered on the upper part of each bed apparatus 8 on which 2 l of a care recipient is lying, each bed apparatus 8 is guided by a guide wire (individual wire guide wire 32, passage guide wire 33). 34, 34, and evacuation route guide lines 36, 37), and moves (evacuates) to an evacuation place (not shown) outside the structure 1.

  Thus, when conducting fire evacuation training at nursing homes, etc., conventionally, for example, multiple nurses moved from bed to wheelchairs etc. and moved (evacuated) outdoors. However, the physical burden on the nurse and the care recipient was great, but by conducting fire evacuation training with the emergency evacuation system of the present invention described above, both the nurse and the care recipient need not be bothered. The lying bed apparatus 8 can be automatically run and moved (evacuated) to the outside without any physical burden. This makes this fire evacuation training a comfortable sunbathing for care recipients who usually lie on the bed apparatus 8 in a private room, especially on sunny days, and is troublesome for nurses. It is possible to easily change the mood of the person requiring care without causing it.

  When the bed apparatus 8 is moved again to the private room after the end of the fire evacuation training, the nurse turns on a fire training release switch (not shown) provided in the electric cart unit 9 to turn on the electric cart control unit 19. A drive signal is output to a drive motor (not shown) of the first travel drive unit 13 to drive the drive motor (not shown) to rotate in the reverse direction (passage 30, 31 side). Then, the magnetic sensor 17b at the rear (rear wheels 12a, 12b side) detects magnetic fields generated from the guide wires (evacuation route guide wires 36, 37, passage guide wires 33, 34, and private room guide wire 32).

  Then, the electric cart control unit 19 controls the second steering unit 16 to steer the rear wheels 12a and 12b so that the bed apparatus 8 returns to the predetermined private rooms 2a to 2l based on the detection signal. Similarly, when each bed apparatus 8 travels to the private room side, it is detected that the other ultrasonic sensor (a rear-end collision prevention sensor) 18b provided in each bed apparatus 8 has approached the front bed apparatus more than a predetermined amount. Then, a collision signal is prevented by outputting a stop signal from the electric cart control unit 19 to the first traveling drive unit 13 to stop the bed apparatus 8. When the ultrasonic sensor 18b detects that the rear side (rear wheel 12a, 12b side) of each bed apparatus 8 that has returned to the private chambers 2a to 2l has approached the wall surface on the window side, the electric cart control unit 19 A stop signal is output to the traveling drive unit 13 to stop the bed apparatus 8.

  Thus, even when the bed apparatus 8 is moved to the private room again after the fire evacuation training is completed, all the care recipients are surely brought to the original private room together with the bed apparatus 8 without bothering the nurse. Can be moved.

  In the above embodiment, the emergency evacuation system at the time of a fire according to the present invention is applied to a one-story structure (for example, a nursing home for the elderly). The present invention can be similarly applied by adopting a structure in which the upper floor and the lower floor are connected by an escape route having a slope.

  Moreover, in the said embodiment, it was the structure which makes it run (evacuate) in order from the private room (private room 2a, 2g) side near the escape path 35 with respect to each bed apparatus 8 of private room 2a-2l at the time of a fire outbreak. You may run (evacuate) each bed apparatus 8 of private room 2a-2l simultaneously at the time of generating. In this case, when it is detected that an ultrasonic sensor (a rear-end collision prevention sensor) 18a provided in each bed apparatus 8 has approached the bed apparatus 8 ahead of a predetermined distance or more, the electric cart control unit 19 moves to the second traveling drive unit 14. A stop signal is output to temporarily stop the bed apparatus 8, and the traveling is resumed after the approaching state is canceled.

  Further, in the above embodiment, only the upper space of the electric bed 22 of the bed apparatus 8 is covered with the flameproof sheet 25 when a fire occurs, but it is also folded on the four side surfaces of the frame-like frame 24 of the bed portion 10. By setting the flameproof sheet, the flameproof sheet may be lowered from above by driving by the flameproof sheet drive unit 26 in the event of a fire so as to cover the four side surfaces of the bed portion 10. In this case, the bed apparatus 8 can be run (evacuated) with the upper portion of the bed portion 10 and all the side surfaces covered with the flameproof sheet.

  Moreover, in the said embodiment, although it was the structure which integrally provided the wireless transmission part (not shown) which has the antenna 7a in the fire alarm control panel 7, the wireless transmission part (not shown) which has the separated antenna 7a. May be provided, for example, on the ceiling of each of the individual rooms 2a to 2l, and a signal line may be connected between the fire alarm control panel 7 and the wireless transmission units (not shown) provided in the individual rooms 2a to 2l.

  A first guide line 58 and a second guide line 59 are respectively embedded in the floor surface of the room 51 and the evacuation path 57 in a continuous manner. The distal end side of the second guide wire 59 extends to the evacuation site 56. An alternating current is applied to the first and second induction wires 58 and 59 from an alternating current power source (not shown), and the strength of the magnetic field generated by the application of the alternating current is detected by the magnetic sensors 17a and 17b (see FIG. 3). .

  On the floor surface of the room 51, two metal rails (not shown) are installed so as to extend along both sides of the first guide wire 58, and the bed apparatus is placed on each rail (not shown). 8 (electric cart part 9) wheels (front wheels 11a, 11b, rear wheels 12a, 12b) move. As a result, the traveling surfaces of the wheels (front wheels 11a and 11b, rear wheels 12a and 12b) are reliably maintained even in a fire. The escape path 57 is made of concrete.

  Next, the evacuation operation of the bed apparatus 8 by the emergency evacuation system at the time of the fire of the one-story house 50 will be described.

  When a fire occurs in the one-storied house 50, one of the fire alarms 6 in the one-story house 50 detects the fire, and when an alarm is issued, the fire alarm 6 fires via a signal line (not shown). A detection signal is input to the fire alarm control panel 7.

  When a fire detection signal is input from the fire alarm 6, the fire alarm control panel 7 outputs a door opening signal to a door drive unit (not shown) via a signal line (not shown) and is closed. Open the automatic door 55. Further, when a fire detection signal is input from the fire alarm device 6, the fire alarm control panel 7 transmits a radio signal from the antenna 7 a to the electric cart control unit 19 (see FIG. 3) of the bed device 8 (electric cart unit 9). Is transmitted to the antenna 19a (radio receiver 19b).

  As in the first embodiment, when the electric cart control unit 19 receives a radio signal, it first outputs a drive signal to the flameproof sheet drive unit 26. The winding mechanism (not shown) is driven by the driving of the flameproof sheet drive unit 26, and as shown in FIG. 5, the wound flameproof sheet 25 moves to the front side (the head side of the care recipient C). It is drawn out and covers the upper space of the bed apparatus 8. Thereby, since the upper part of the care recipient C sleeping on the electric bed 22 can be covered with the flameproof sheet 25, it is possible to prevent sparks and the like from falling on the care recipient C during evacuation.

  Then, after the upper space of the electric bed 22 is covered with the flameproof sheet 25, the electric cart control unit 19 sends a drive signal to a drive motor (not shown) of the second traveling drive unit 14 based on the received radio signal. And the drive motor (not shown) is rotationally driven to cause the bed apparatus 8 to travel to the automatic door 55 side.

  When the bed apparatus 8 starts traveling toward the automatic door 55, the magnetic field generated from the first guide wire 58 is detected by the magnetic sensor 17a on the front (front wheels 11a, 11b side). Then, the electric cart control unit 19 causes the bed apparatus 8 to travel along the first and second guide lines 58 and 59 through the opened automatic door 55 on the escape path 57 based on the detection signal. The first steering unit 15 is controlled to steer the front wheels 11a and 11b. Then, the bed apparatus 8 travels (moves) to the evacuation place 56 ahead of the evacuation path 57 and automatically stops.

  Thus, according to the emergency evacuation system at the time of the fire in the present invention described above, when a fire occurs in the one-story house 50, the outer wall surface of the room 51 is based on the fire detection signal output from the fire alarm device 6. After automatically opening the automatic door 55 on the 51a side, the flameproof sheet 25 is automatically covered on the upper part of the bed device 8 where the care recipient C is sleeping, and then the bed device 8 is moved to the first and second sides. By automatically running along the guide lines 58 and 59, it is possible to evacuate to a safe outdoor evacuation place 56 in a short time.

  Therefore, even if there is only one family to care for, it is possible to reliably evacuate the bedridden caregiver together with the bed apparatus 8 to a safe evacuation place without bothering the family.

  In addition, as described in the first embodiment, the bed apparatus 8 is automatically run along the first and second guide lines 58 and 59 for the purpose of fire evacuation drills and the like, so that an outdoor evacuation site is provided. 56 can be moved. This makes it possible to easily move the care recipient together with the bed apparatus 8 from the room 51 to the outdoor evacuation place 56 on a day with good weather, such as during sunny weather, so that sunbathing can be performed.
