Abstract

PROBLEM TO BE SOLVED: To provide an urgent evacuation method for tenants using an elevator in a social welfare institution or the like that allows all of bedridden tenants and wheel-chaired tenants to be transferred into the elevator efficiently and to be carried to a rooftop reliably in short time for evacuation, when a tsunami or a flood occurs.SOLUTION: The urgent evacuation method comprises providing an elevator E along an emergency staircase H in advance, transferring bedridden tenants B and wheel-chaired tenants K into each of multistage floors 21, 22 of an elevator basket 2 simultaneously at each building floor, pulling up and stopping the elevator E by one or a half floor height portion, carrying out the bedridden tenants B and the wheel-chaired tenants K sequentially from an upper floor onto a rooftop O for evacuation. As alternative pulling-up means of the elevator basket 2, a man-powered pulling-up structure can be used for the urgent evacuation method.

Description

  The present invention is an emergency evacuation method for evacuating (carrying) a bedridden bed user or a wheelchair user resident to the rooftop in the event of a tsunami or flood, especially in a social welfare facility, etc. It relates to emergency evacuation methods for residents using elevators.

  Currently, when a tsunami or flood occurs, it is common to evacuate to public facilities such as high schools and public halls established by local governments. Residents who were far away were not able to evacuate in time and were more likely to be swallowed by the tsunami after escaping. In particular, residents near the coast could hardly evacuate to the hills in a short time, so many people were killed in the Great East Japan Earthquake.

  For this reason, many simple shelters for evacuation and evacuation towers that evacuate in a short time when a tsunami occurs have been proposed. For example, there are floating type, fixed type on the ground, and underground type. However, these facilities are intended for healthy people, so it is difficult to use for those who have difficulty walking, and residents in special welfare homes, nursing homes, and facilities for the disabled are evacuated from the tsunami. It was difficult. Therefore, the current situation is that people who have difficulty walking are required to develop facilities and devices for evacuating from the tsunami.

  In addition, when evacuating using an elevator, especially in the event of a fire, especially for a wheelchair user, a “fire evacuation elevator” that can be used for a long time while evacuating while appropriately exhausting smoke is a special feature. Open 2009-51613. However, since JP 2009-51613 has one elevator box, and this elevator box stops on each floor and carries wheelchair users etc., the number of people carried at one time is limited, and the bedridden bed It was difficult to put users together in the elevator box. Therefore, it is difficult to put many bed users and wheelchair users at the same time as in the present invention, and it is difficult to evacuate those people to the roof almost simultaneously, and there is no such idea. Met. Furthermore, JP-A-2009-51613 is targeted at the time of a fire and is intended to be lowered to the ground, and is different from the present invention.

JP 2009-51613 A

  The present invention enables bedridden bed users and wheelchair users to get on elevators efficiently when tsunamis and floods occur, and can transport everyone on the roof in a short time and evacuate. The purpose is to provide emergency evacuation methods for residents who use elevators in social welfare facilities.

  The present invention has been made in view of the above situation, that is, an elevator is installed in advance along an emergency staircase, and a bedridden bed user or a wheelchair user can be turned into an elevator basket having a multi-level floor. It is an emergency evacuation method for residents to get on the floor at the same time, raise the elevator by the height of the first floor or half-floor, and sequentially carry out the evacuation from the upper floor. Further, the lifting means of the elevator car may be a structure that can be lifted by human power, and an emergency evacuation method for evacuating using the structure may be used.

  Residents who use bed (B) and wheelchair users (K) as claimed in claim 1 to evacuate from the tsunami to the building rooftop (O) using the elevator (E) It is an evacuation method, and is arranged so as to be able to ascend inside the column frame (1) of the elevator (E) erected along the emergency staircase (H) of the building, and inside the column frame (1) Elevator (E) equipped with at least an elevator car (2) having a multi-level floor (21) corresponding to each floor and a lifting means (3) for lifting the elevator car (2) After the floor (21) of the elevator car (2) is attached to the position corresponding to each floor, the bed user (B) and the wheelchair user (K) enter the elevator (E) at the same time from each floor, Next, lift (E) by the height of the first floor When the tsunami or flooding occurs by evacuating by escaping from the upper floor to the rooftop (O) and evacuating in order, such as nursing homes, nursing homes, and facilities for the disabled All the bedridden bed users (B) and wheelchair users (K) occupants of social welfare facilities can be efficiently placed on the elevator and evacuated to the roof in a short time and surely.

  The floor (21) of the elevator car (2) is attached to a new floor (22) divided into two equal parts in the vertical direction on each floor as in claim 2, and the bed user (B) and wheelchair users from each floor The person (K) enters the floor (21) of the elevator (E) at the same time. First, the elevator (E) rises by the height of the half floor and stops, and the bed user (from each floor to the floor (22) ( B) and wheelchair users (K) enter the elevator (E) at the same time, then lift the elevator (E) by half the height of the floor and stop, then carry it out from the upper floor to the rooftop (O) sequentially By using the evacuation method for evacuation, the same effect as in claim 1 can be obtained, and further, the bed user (B) and the wheelchair user (K) can be evacuated earlier.

  As shown in claim 3, the lifting means (3) of the elevator car (2) is structured to be lifted by human power, and the elevator (E) can be operated even during a power failure by evacuating using it. Therefore, it becomes possible to carry out and evacuate more reliably all the residents of the bed user (B) and the wheelchair user (K) to the rooftop (O).

It is explanatory drawing which shows the process of this evacuation method. It is explanatory drawing which shows another process of this evacuation method. It is explanatory drawing which shows the state in which the bed user and the wheelchair user got in the elevator basket of this embodiment. It is explanatory drawing which shows the state in which the elevator of this embodiment was installed along the emergency staircase. It is explanatory drawing which shows the support | pillar frame body and elevator cage of this embodiment.

  The figure number which shows the outline | summary of the elevator used by embodiment of this invention is demonstrated. (1) is a pillar frame body of an elevator (E) erected along the emergency staircase (H) as shown in FIG. 4, and the pillar frame body (1) is opened upward. (2) is an elevator car which is arranged to be able to ascend inside the support frame (1) and has a multi-stage floor (21) corresponding to each floor as shown in FIG. ) Is surrounded by a wire mesh (23) except for the entrance / exit direction. Moreover, it is preferable to provide a roof (24) above the elevator car (2). (3) is a lifting means for lifting the elevator car (2), and the lifting means (3) is provided on the roof of the support frame (1). The lifting means (3) includes, as shown in FIGS. 3 and 4, large manual wheels (31) provided on both sides of the support frame (1), a rotating shaft (32) of the manual wheels (31), The take-up drum (33) arranged on the rotating shaft (32), the moving pulley case (34) arranged on the rotating shaft (32) and accommodating the moving pulley, and the take-up drum (33) are wound up. It comprises at least a wire (not shown). The tip of the wire is connected to the lowermost floor (21) of the elevator car (2). It should be noted that the lifting means (3) may be structured to be lifted not by human power but by using a drive motor with an emergency power source.

  Next, the process of the evacuation method of this invention is demonstrated based on FIG. In addition, although the building in a figure is 3 stories, the number of stories is not limited to 3 stories. First of all, when a tsunami is issued, the residents promptly evacuate by broadcasting in the hall, etc., and each staff member prepares for evacuation at the department in charge. As preparation for this evacuation, first, one person is arranged as an operator in charge (hereinafter referred to as an operator) on both sides of the elevator (E) of the elevator (E) on the rooftop (O). The operator operates the manual wheel (31) of the lifting means (3) to play the role of human power (human power) for lifting the elevator car (2). Next, the staff instructed in charge (hereinafter referred to as the instructor) is placed on the mezzanine landing on the emergency stairs (H), and 2 to 3 care workers (hereinafter referred to as caregivers) on the rooftop landing on the emergency stairs (H). Place. In addition, caregivers on each floor are assigned a predetermined number of staff. The caregiver on each floor moves the resident to the elevator (E). This completes the evacuation preparation.

  Next, the process proceeds to a step of starting the elevator (E). This process will be described in detail. At this time, the multi-level floor (21) is on standby at a level substantially equal to the floor of each floor. First, as Step 1, the caregiver on each floor carries a resident (caregiver) from each floor into the elevator car (2). At this time, as shown in FIG. 1, on the first floor, two bedridden bed users (B) are pushed into the back, and two wheelchair users (K) are put in the back and front to wait (FIG. 3). reference). On the second floor, one bed bed user (B) pushes in to the back and four wheelchair users (K) stand in the back and front. On the 3rd floor, 6 wheelchair users (K) stand in front and back. In addition, this accommodation number is determined by the width of the elevator car (2). As described above, when the elevator car (2) is full or the evacuee is finished, the lifting means (3) is operated after pressing the completion button or the like.

  The operator operates the manual wheel (31) of the lifting means (3) based on the signal from the instructor, so that the floor (21) on the top floor (3F) of the elevator car (2) is the floor on the roof (O). Lift until it is almost level with the surface. At this time, the caregiver on the rooftop (O) can evacuate six wheelchair users (K) to the rooftop (O) by carrying out the resident inside and moving it to the rooftop (O). This completes step 2.

  Next, after step 2, the operator operates the manual wheel (31) as instructed so that the second floor (21) of the elevator car (2) is approximately the same height as the floor of the roof (O). Lift until it stops and stop. In the same manner as described above, it is carried out of the elevator car (2) and moved to the roof (O). Then, one bed user (B) and four wheelchair users (K) can evacuate to the rooftop (O). This completes step 3. In the same manner as described above, the elevator car (2) is lifted and stopped until the floor (21) on the first floor becomes substantially the same level as the floor of the roof (O). Then, it is carried out of the elevator car (2) and moved to the rooftop (O). Then, two bed users (B) and two wheelchair users (K) can evacuate to the rooftop (O). This completes step 4. At this time, the elevator car (2) protrudes upward from the rooftop (O). The operator operates the manual wheel (31) in the opposite direction as instructed, lowers the elevator car (2) whose interior is empty, returns it to the original standby position, and the process 5 ends. In the case of Step 5, since the elevator car (2) naturally falls by its own weight, the operator lightly touches the manual wheel (31) to brake the elevator car (2) so that it falls gently. The elevator car (2) is lowered until it reaches the ground. This completes one cycle of steps. The time required for each step is approximately 15 to 20 seconds.

  If steps 1 to 5 are repeated several times as described above, all of the bed users (B) and wheelchair users (K) who are tenants use the elevator (E) and use the roof (O). It is possible to evacuate by carrying it out in a short time.

  It demonstrates based on another process of the evacuation method of this invention. Compared with the previous step, this step is provided with a floor (22) that bisects in the vertical direction at the middle position of each of the multi-stage floors (21), so that the elevator car (2) can accommodate approximately 2 people. Double. At this time, the top floor is not doubled. Then, the height at which the elevator car (2) is lifted by the lifting means (3) is raised by half of the above, that is, by half floors in sequence, stopped, carried to the rooftop (O) and evacuated. It will be a thing. Therefore, more residents can be put in the elevator car (2) than in the above process, so that the elevator (E) can be put in efficiently and the occupant bed user (B) or The wheelchair user (K) can evacuate to the rooftop (O) within a shorter time than the above case.

  This separate process will be described in detail with reference to FIG. The evacuation preparation is completed in advance in the same manner as the above process. First, as step 1, the caregiver on each floor carries 6 residents (K) as wheelchair users (K) from the floors into the elevator car (2) in the same manner as described above. At this time, the distance between the floor (21) and the floor (22) is about 1.5 meters. For this reason, there is no problem with carrying a bed user (B) or a wheelchair user (K), but when a caregiver gets in, he / she waits in a middle waist posture or a sitting posture. After that, when the floor (21) of each floor is full, after the completion button or the like is pressed or a voice is spoken, the lifting means (3) is operated.

  The operator operates the manual wheel (31) of the lifting means (3) based on the signal from the instructor, and lifts and stops the elevator car (2) by half a floor in the same manner as in the above process of FIG. . Then, each floor (22) of the elevator car (2) is approximately the same height as the floors of the 2nd and 3rd floors, so the wheelchair can be used in the elevator car (2) from the 2nd and 3rd floors at the same time as above. Step 2 is completed by bringing in six persons (K). In addition, it is not limited to a wheelchair user (K) to carry in the said elevator basket (2) inside at this time.

  As above, when the 2nd and 3rd floors (22) are full, after pressing the completion button or talking to each other, the operator lifts the elevator car (2) half a floor and stops. Let The caregiver on the rooftop (O) carries 6 wheelchair users (K) inside and moves them to the rooftop (O), thereby completing the step 3. Thereafter, the operator lifts the elevator car (2) by half a floor and stops it. Then, the caregiver carries six wheelchair users (K) inside and moves them to the rooftop (O), thereby completing the step 4. Further, the operator lifts the elevator car (2) by half a floor and stops it. The caregiver carries six wheelchair users (K) inside and moves them to the rooftop (O), thereby completing Step 5. Then, the elevator car (2) is lifted by half the floor and stopped by the operator in the same manner as described above, and the caregiver sequentially carries six wheelchair users (K) to the roof (O) in the same manner as described above. By moving, step 6 and step 7 are completed.

  After all wheelchair users (K) entering the elevator car (2) evacuate to the rooftop (O), the lifting means (3) is operated to lower the elevator car (2) to the first standby position. As a result, step 8 is completed. In the case of step 8, since the elevator car (2) naturally falls by its own weight, the operator lightly touches the manual wheel (31) to brake so that the elevator car (2) falls gently. The time required for one cycle from Step 1 to Step 8 is about 150 seconds. After that, the occupants who were waiting on each floor quickly carry the wheelchair user (K) into the elevator car (2) according to the above procedure, and operate the lifting means (3) to increase the height of the half floor. By raising and stopping and repeating the above steps, all the residents are sequentially carried out to the rooftop (O) for evacuation.

  In addition, based on the said separate process, the evacuation method at the time of the earthquake of 80 residents (including 20 bedridden elderly people) is assumed, for example. The occupancy at this time is based on evacuation, for example, 8 bed users (B) and 24 wheelchair users (K) on the 3rd floor, 8 bed users (B) and 2 wheelchairs on the 2nd floor There are 24 users (K), 4 bed users (B) and 12 wheelchair users (K) on the first floor. The number of people that can be carried into the elevator car (2) for one cycle can be twice as large as the first and second floors, so the above process must be repeated four cycles. Accordingly, although 600 seconds, which is four times 150 seconds, the process 8 is unnecessary at the end, if approximately 10 seconds are subtracted, the total required time is 590 seconds, that is, 9 minutes and 50 seconds.

  In this way, bed users (B) who are bedridden or wheelchair users (K) are evacuated from the tsunami in social welfare facilities such as nursing homes, nursing homes, and facilities for the disabled. However, it was extremely difficult in the past, but by using the elevator (E) having the multilayer elevator basket (2) used in the method of the present invention, the bed user (B) who is a resident or the wheelchair user (K) ) Can be evacuated to the rooftop (O) within a short time.
