1 is a schematic diagram showing a state in which a movable bed is moved to the outside of a building in an emergency situation in a descending evacuation device according to an embodiment of the present invention.

First, referring to FIG. 1, when an emergency such as a fire occurs, the movable bed 20 located inside the building 11 is moved through the moving unit 22, and the opening of the door 13 According to this, it is located outside 12 of the building.

In this case, the movable bed 20 may be a hospital bed on which the patient lies directly in normal times when an emergency does not occur, and thus the patient lying on the bed 21 is the evacuation assistant 14 as it is in an emergency situation. With assistance it can be positioned on the exterior 12 of the building.

Therefore, especially in the case of evacuation weak persons such as the elderly, they can be moved to a separate mobile body in an emergency situation while lying on a bed, or can be moved to the outside of a building together with the mobile bed 20 quickly and safely without the inconvenience of having to move directly. there is.

Figure 2 is a schematic view of the moving state of the mobile bed of Figure 1 observed from the outside of the building.

Referring to FIG. 2, when the opening door 13 is opened as in FIG. 1, the movable bed 20 is exposed to the outside 12 of the building and is located.

On the other hand, when the movable bed 20 is located outside the building 12, in order to prevent the movable bed 20 from falling, the footrest unit 30 is primarily positioned outside the building 12. Thus, the moving part 22 of the movable bed 20 is located on the footrest part 30.

In addition, for the subsequent fall of the movable bed 20, the wire 23 extending from the movable bed 20 is fixed on the transfer block 300 through the fixing block 200.

In this case, the wire 23 may be extended to both sides of the movable bed 20, respectively, and accordingly, both sides of the movable bed 20 are fixed on the transfer block 300.

This fixed state will be described in detail with reference to FIGS. 3A and 3B.

FIG. 3A is an enlarged view of part 'A' of FIG. 2 , and FIG. 3B is a side view schematically illustrating FIG. 3A .

3A and 3B, a fixing part 24 is fixed to the center of the wires 23 extending from both sides of the movable bed 20, and the evacuation assistant 14 is attached to the fixing part 24 In the holding state, the fixing part 24 is fixed on the transfer block 300 through the fixing block 200.

In this case, as will be described later, the fixing block 200 is formed with a fixing groove (220, see FIG. 9B), and the transfer block 300 is also formed with a transfer groove 320 as will be described later.

Accordingly, in a state in which the fixing groove 220 and the transfer groove 320 are aligned in the vertical direction, the fixing portion 24 is positioned as the transfer groove 320 through the fixing groove 220, and thus Accordingly, the movable bed 20 is fixed to the transport blocks 300 on both sides.

Meanwhile, detailed structures of the fixing block 200 and the transfer block 300 will be described later.

4a is a schematic diagram showing a state in which the movable bed of FIG. 1 is located outside the building before descending, and FIG. 4b is a side view illustrating a state of the movable bed of FIG. 4a.

Referring to FIG. 4A, as described above, a pair of wires 23 extending from the wire insertion portion 25 of the movable bed 20 are located on both sides of the movable bed 20 and on the outside of the building. is fixed to a pair of transport blocks 300, so that the movable bed 20 is completely positioned to the outside 12 of the building.

In this case, referring to FIG. 4B , the guide frame 100 extends vertically along the exterior 12 of the building, and one fixing block is fixed on the guide frame 100 for each floor.

That is, the n-th fixing block 200 is fixed on the guide frame 100 in the n-layer, and the n-1-th fixing block 201 is fixed on the guide frame 100 in the n-1 layer.

On the other hand, the moving blocks move in the vertical direction along the guide frame 100, and the n-th transport block 300 located in the n-layer follows the guide frame 100 between the n-layer and the n-1 layer. It moves in the vertical direction, and the n-1th transfer block 301 located on the n-1 floor moves vertically along the guide frame 100 between the n-1 layer and the n-2 layer.

That is, considering the location where the movable bed 20 is exposed to the outside of the building, the n-th fixing block 200 is fixed to the central portion of the n-th floor, and the n−1-th fixing block 201 is n- When fixed to the central part of the first floor, the n-th conveying block 300 moves up and down along the guide frame 100 between the n-th fixing block 200 and the n−1-th fixing block 201. is moved in the direction

Similarly, the n−1 th transfer block 301 moves in the vertical direction along the guide frame 100 between the n−1 th fixing block 201 and the n−2 th fixing block (not shown). do.

Meanwhile, the elastic support part 400 is also provided for each layer, and provides a predetermined elastic force to the transfer block provided for each layer.

That is, the n-th elastic support part 400 located in the n-th layer is connected to the n-th transfer block 300 through an extension wire 410, and provides a predetermined elastic force to the n-th transfer block 300. In this case, the elastic force is substantially an external force acting upward on the n-th transfer block 300, and the n-th transfer block 300 is moved downward by the weight of the movable bed 20. Then, when the movable bed 20 is removed to the outside, it corresponds to an external force that restores the n-th transfer block 300 to its original position.

In other words, as will be described later, the n-th transfer block 300 is positioned in close contact with the lower surface of the n-th fixing block 200 by the elastic force of the n-th elastic support part 400 or an external force in the upward direction. do.

At this time, when the movable bed 20 is fixed to the nth transfer block 300, the weight of the movable bed 20 is greater than the elastic force or the external force in the upward direction, so the movable bed 20 It descends and the n-th transfer block 300 is positioned on the upper surface of the n−1-th fixing block 201.

Then, when the fixed state of the movable bed 20 is changed to the n−1 th transport block 301, the n th transport block 300 rises again by the elastic force or an external force in the upward direction, It is positioned in close contact with the lower surface of the n-th fixing block 200, which is the initial position.

As described above, the transfer block 300 rises along the guide frame 100 by the elastic force or external force provided by the elastic support part 400 .

In this case, since the transfer block 300 moves only between the n-layer and the n-1 layer, the elastic support part 400 must provide an elastic force or an external force to the transfer block located on each layer, one for each layer. should be provided

5 is a front view schematically illustrating a state in which the movable bed of FIG. 4A is located outside the building before descending.

Referring to FIG. 5, a pair of guide frames 100 extend on both sides of the movable bed 20, and a pair of fixing blocks 200 for each floor ) is fixed to each.

In addition, a pair of transfer blocks 300 are moved in the vertical direction between the fixed blocks spaced apart in the vertical direction. When the movable bed 20 is fixed, the movable bed 20 and the lower portion It moves, and when the movable bed 20 is removed, it moves upward.

At this time, in the process of fixing the movable bed 20 to the transfer block 300 while initially positioning the movable bed 20 outside the building, securing a stable position of the movable bed 20 and preventing a fall To do this, the footrest part 30 may be located on each floor, and the falling of the movable bed 20 starts as the footrest part 30 is removed.

Hereinafter, the lowered state of the movable bed will be described.

6 is a schematic diagram showing a state in which the movable bed of FIG. 1 starts descending. 7 is an enlarged view showing a state of a transfer block in a state in which the movable bed of FIG. 1 descends.

First, referring to FIG. 6, the movable bed 20, to which the wire 23 is fixed to the transport block 200 while being located outside 12 of the building, the scaffolding portion 30 is removed downward. As it is, it descends downward together with the transfer block 200.

In this case, referring to FIG. 7 , when the movable bed 20 descends downward, the wire 23 extending from the movable bed 20 is moved to the transfer block 300 by the fixing part 24. Is fixed to, whereby the stable descent of the movable bed (20) is possible.

In addition, as described above, the transport block 300 descends along the guide frame 100 between the n-floor and the n-1 floor, and the movable bed 20 is completely moved to the n-1 floor. Afterwards, the transfer block 300 returns to the n-layer again by the elastic force of the extension wire 410 connected to the transfer block 300 .

The movement state of the n-th transfer block 300 located in the n-layer is modeled in more detail in FIG. 8 below.

FIG. 8 is a side view schematically illustrating a state in which the movable bed of FIG. 1 descends by one floor from the n floor to the n−1 floor.

That is, referring to FIG. 8 , the movable bed 20 located on the n floor descends to the n-1 floor together with the n th transport block 300 as the footrest unit 30 is removed.

At this time, when the n-th transport block 300 is located on top of the n-1-th fixing block 201 fixed to the n-1 floor, the movable bed 20 is the n-th transport block 300 is fixed to the n−1 th transfer block 301 through the n−1 th fixing block 201, and then, the n th transfer block 300 has elasticity provided from the n th elastic support part 400. It rises again by restoring force or an external force in the upward direction, and comes into close contact with the lower surface of the n-th fixing block 200 .

On the other hand, the descending state of the movable bed from the nth floor to the n−1 floor has been described only starting at the nth floor, but the movable bed may start to descend after moving from the inside to the outside of the building at n−1. .

That is, the movable bed in this embodiment can be moved from the inside to the outside on each floor of the building and then descended, and if the movable bed is moved to the outside of the building on a plurality of floors and does not interfere with each other sequentially can be descended to

On the other hand, in the following, to explain the change in the fixed state of the fixing part 24 between the fixing block 200 and the transfer block 300, the structure of the fixing block 200 and the transfer block 300 will be explained first.

9A is a front view showing a transfer block in a descending type evacuation device according to an embodiment of the present invention, and FIG. 9B is a front view showing a fixed block.

First, referring to FIG. 9A , the transfer blocks 300 and 301 include a transfer block unit 310 , a transfer pinion 330 , a transfer gear 340 and a transfer rack 350 .

The transfer block unit 310 is transferred along the guide frame 100 and forms the body of the transfer block in a block shape.

In this case, a transfer groove part 320 is formed at the center of the transfer block part 310, and the fixing part 24 described above may be inserted into the transfer groove part 320.

The transfer gear 340 is located inside the transfer block 310, and gear teeth are formed along the outer circumferential surface. In addition, the transfer gear 340 rotates according to the movement of the fixed rack 250 when the gear teeth are engaged with the fixing rack 250 (see FIG. 9B) of the fixing block, which will be described later.

The feed pinion 330 is fixed to the feed gear 340, and as shown, the feed pinion 330 overlaps with the feed gear 340 and is fixed.

However, the feed gear 340 has a circular plate shape, but the feed pinion 330 has a 'U' shape as a whole, and the feed pinion groove 331 (see FIG. 11) is formed to open in one direction. .

Thus, when the feed pinion groove part 331 is aligned with the feed groove part 320 according to the rotation of the feed gear 340, the groove into which the fixing part 24 can be inserted is formed as shown in FIG. 9A. formed, the fixing part 24 may be located up to the inner side of the feed pinion 330.

On the other hand, if the feed pinion groove part 331 is not aligned with the feed groove part 320 according to the rotation of the feed gear 340, the fixing part 24 is positioned toward the inside of the feed pinion 330. will not be able to

The transfer rack 350 extends upward from one side of the transfer block unit 310, and gear teeth are formed on one surface. In the case of the transfer rack 350, it may be gear-coupled with a fixed gear 240 (see FIG. 9B) of the fixing block to be described later, and the fixed gear 240 rotates as the transfer rack 350 moves. do.

Also, referring to FIG. 9B , the fixing blocks 200 and 201 include a fixing block part 210 , a fixing pinion 230 , a fixing gear 240 and a fixing rack 250 .

The fixing block part 210 is fixed on the guide frame 100 and forms the body of the fixing block in a block shape.

In this case, a fixing groove part 220 is formed at the center of the fixing block part 210, and the fixing part 24 described above may be inserted into the fixing groove part 220.

The fixed gear 240 is located inside the fixed block part 210, and gear teeth are formed along the outer circumferential surface. In addition, the fixed gear 240 rotates according to the movement of the transfer rack 350 when the gear teeth mesh with the transfer rack 350 .

The fixed pinion 230 is fixed to the fixed gear 240, and as shown, the fixed pinion 230 overlaps with the fixed gear 240 and is fixed.

However, the fixed gear 240 has a circular plate shape, but the fixed pinion 230 has an '11' shape as a whole, and a fixed pinion groove 231 (see FIG. 11) is formed along the center to open.

Thus, when the fixed pinion groove part 231 is aligned with the fixed groove part 220 according to the rotation of the fixed gear 240, a groove into which the fixed part 24 can be inserted is formed, and the The top 24 passes through the fixing groove 220 and the fixing pinion groove 231 .

On the other hand, if the fixed pinion groove part 231 is not aligned with the fixed groove part 220 according to the rotation of the fixed gear 240, as shown in FIG. 9B, the fixed part 24 is the fixed pinion It cannot be located inside the 230, and is located only on the fixing groove 220.

The fixed rack 250 extends upward from one side of the fixed block portion 210, and gear teeth are formed on one surface. In this case, the side to which the fixed rack 250 extends must be opposite to the side to which the previous transfer rack 350 extends. Through this, the transfer rack 350 and the fixed rack 250 may not interfere with each other.

In the case of the fixed rack 250, as described above, it can be gear-coupled with the transfer gear 340 of the transfer block, and the transfer gear 340 rotates as the fixed rack 250 moves. .

10A to 10E are images showing the coupling state of the transport block and the fixed block in a state in which the movable bed descends by one floor as shown in FIG. 8 . FIG. 11 is a schematic diagram briefly showing images of the coupled state of FIGS. 10A to 10E.

In this case, for convenience of description, FIGS. 10A to 10E show a coupling state of a transport block and a fixed block located on one side (left side), and FIG. 11 shows a coupling state of a transport block and a fixed block located on the other side (right side). .

As described above with reference to FIG. 8, referring to FIG. 10E, when the movable bed 20 located on the n-th floor is fixed to the n-th transport block 300 and moves to the n-1 floor, the n-th The transfer block 300 descends toward the n-1st fixed block 201 located on the n-1 floor.

At this time, referring to FIGS. 10B and 11 , while the fixing rack 250 of the n-1st fixing block 201 is inserted into the n-th conveying block 300, the transfer gear 340 and the gear will combine

Thus, referring to FIGS. 10C, 10D, and 11, as the fixed rack 250 is relatively inserted into the n-th transfer block 300, the transfer gear 340 rotates, and the As the transfer gear 340 rotates, the transfer pinion 330 also rotates. Accordingly, the feed pinion groove portion 331, which is opened upward and fixed the position of the fixing portion 24, is rotated and opened downward.

Thus, referring to FIGS. 10E and 11 , as the feed pinion groove part 331 opens downward, the fixing part 24 moves downward and is in line with the feed pinion groove part 331. The fixing part 24 is moved to the inside of the fixing groove 220 of the aligned n−1 th fixing block 201 and positioned.

As described above, when the fixing part 24 is moved to the n−1 th fixing block 201 and positioned, the n th transfer block 300 loses the gravity acted by the movable bed 20, It is moved upward again by an external force or an elastic force applied from the n-th elastic support part 400 .

As described above, the n-th transport block 300 moved upward is guided to come into close contact with the lower surface of the n-th fixing block 200 .

This process of inducing the n-th transfer block 300 upward is schematically illustrated in FIGS. 12A and 12B.

12a and 12b are side views schematically showing that the coupling state of the transport block and the fixed block is varied in order to descend to the n-2 floor in a state in which the movable bed of FIG. 1 descends to the n-1 floor.

That is, referring to FIG. 12A, when the fixing part 24 is fixed to the n-1st fixing block 201 of the n-1 floor, the movable bed 20 is first located on the n-1 floor and At the same time, the n-th transfer block 300 rises in the upper direction, that is, to the n-layer, due to the elastic force by the n-th extension wire 410 extending from the n-th elastic support part 400 or an external force in the upward direction. .

Thus, referring to FIG. 12B, the nth transfer block 300 rises to the lower surface of the nth fixing block 200 fixed to the nth floor.

In addition, as will be described later, the movable bed 20 fixed to the n-1 th fixing block 201 is coupled with the n-1 th transport block 301 and the n-1 th fixing block 201, It is fixed onto the n-1 transfer block 301.

Therefore, since the weight of the movable bed 20 is greater than the elastic force applied to the n-1th transfer block 301 or the external force in the upward direction, the movable bed 20 moves downward again, that is, in the n-2 descend to the floor.

At this time, the state in which the fixing part 24 of the movable bed 20 is moved from the n−1 th fixing block 201 to the n−1 th transfer block 301 is as shown in the following figures.

13A to 13D are images showing that the coupling state of the transfer block and the fixed block is varied as shown in FIGS. 12A and 12B. FIG. 14 is a schematic diagram briefly showing images of the coupling state of FIGS. 13A to 13D.

In this case, for convenience of description, FIGS. 13A to 13D show a coupling state of a transport block and a fixed block located on one side (left side), and FIG. 14 shows a coupling state of a transport block and a fixed block located on the other side (right side). .

That is, referring to FIG. 13A, the n−1 th transfer block 301, which descends downward and rises again, is positioned on the lower surface of the n−1 th fixing block 201 to which the movable bed 20 is fixed. will do

Of course, in FIG. 13a, the n−1 th transport block 301 moves the separate movable bed to the n−2 floor and then rises again, but the n−1 th transport block 301 is in an initial state. It may be in a coupled state on the n−1 th fixing block 201 .

Then, referring to FIGS. 13B, 13C, and 14, as the transfer rack 350 is relatively inserted into the n−1th fixing block 201, the fixed gear 240 rotates. And, according to the rotation of the fixed gear 240, the fixed pinion 230 also rotates. Accordingly, the fixing pinion groove part 231, which is opened in the horizontal direction and prevents the fixing part 24 from being positioned inward, is rotated and opened in the vertical direction.

Thus, as the fixed pinion groove part 231 is opened in the vertical direction, the fixing part 24 moves downward, and the n-1th transfer block aligned with the fixed pinion groove part 231 in a row. The fixing part 24 moves to the inside of the feed groove part 320 and the feed pinion groove part 331 of 301 and is positioned.

At this time, since the feed pinion groove part 331 has a 'U' shape and is open only in the upper direction, the fixing part 24 located inside the feed pinion groove part 331 does not descend further, It is located in a fixed state on the feed pinion groove part 331.

Thus, referring to FIGS. 13D and 14 , when the fixing part 24 is moved to the n−1 th transport block 301, the gravity of the movable bed 20 is applied to the n−1 th transport block. By acting on 301, the n−1 th transport block 301 descends along with the movable bed 20 in the lower direction, that is, to the n−2 floor.

In this way, the movable bed 20 is sequentially descended from the outside of the building through continuous movement between the transport block and the fixed block, and is finally located on the ground.

15A is a schematic view showing a state in which the movable bed of FIG. 1 is located on the ground after evacuation is completed, and FIG. 15B is an enlarged view of 'B' in FIG. 15A.

That is, as shown in FIG. 15A, the movable bed 20 descends one floor at a time as in the process described above and is finally positioned on the ground.

In this way, in a state where the movable bed 20 is located on the ground, the fixing part 24 fixed to the wire 23 extending from the movable bed 20 is located on the transfer pinion 330 of the transfer block As shown in FIG. 15B, the evacuation assistant 15 finally removes the fixing part 24 located on the transfer pinion 330 to the outside, so that the movable bed 20 is completely separated from the building. will do

Then, if necessary, the bed 20 as it is during the movement can be additionally moved by loading it on an ambulance or the like.

16 is a schematic diagram showing a state in which a mobile shelter is moved outside a building in an emergency situation in a descending evacuation device according to an embodiment of the present invention. FIG. 17 is a schematic diagram showing a state in which evacuees board the mobile shelter of FIG. 16 .

16 and 17, a movable shelter 40 may be provided instead of the movable bed 20 described above.

That is, the mobile shelter 40 is provided for each floor, and is assembled to be exposed to the outside 12 of the building in an emergency situation such as fire, and the inside of the mobile shelter 40 exposed to the outside 12 of the building in this way. After a number of evacuees board the space, the mobile shelter 40 may descend downward.

At this time, since the mechanism for lowering the movable shelter 40 is substantially the same as the mechanism for lowering the movable bed 20 described above, duplicate descriptions will be omitted.

In this case, in the case of the movable shelter 40, the moving part 42 may be provided at the lower part, and the wire 43 extends from the side part to be sequentially fixed to the fixed block and the transfer block and descends.

In addition, the shelter 41 of the mobile shelter 40 may be positioned in an unfolded state in normal times and assembled to form a predetermined space inside in an emergency situation, or may be manufactured to form a predetermined space in normal times. .

According to the embodiments of the present invention as described above, in a state where the mobile shelter is located outside the building in an emergency situation, it moves sequentially in the downward direction through the fixed block and the transport block, enabling rapid and stable evacuation of evacuators. In particular, since there is no need for power supply for movement, stable operation is possible even when power is lost.

That is, through the connection and disconnection between the fixed blocks fixed on each floor and the transfer block moved only between two adjacent floors, the mobile shelter is moved down one by one, and stable and rapid evacuation of the evacuated is possible.

In this case, the fixed block and the transfer block are connected to the movable shelter through a wire, and the fixed block and the transfer block are a pinion drive mechanism according to the combination of a rack and a gear, and the wire connected to the movable shelter is connected to the n-layer fixed block. , The stable and rapid evacuation can be implemented by successively delivering the transport block of the n-layer, the fixed block of the n-1 layer, and the transport block of the n-1 layer in order.

In particular, in the case of a mobile shelter, it is possible to evacuate a large number of evacuees at once by forming a predetermined space in an emergency situation, and it can also be a movable bed that is normally used as a patient bed and evacuated with the patient in an emergency situation. Therefore, it is possible to induce more effective evacuation according to the condition of the evacuees or various emergency situations.

Although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art can variously modify and change the present invention without departing from the spirit and scope of the present invention described in the claims below. You will understand that you can.
