Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view showing a state in which a folding evacuation passage according to an embodiment of the present invention is installed on a wall.

First, referring to FIG. 1, the foldable evacuation passage 1 according to the present embodiment is installed under the passage unit 10 and the passage unit 10 installed on a wall surface 5 such as an indoor space or an underground space. It includes an intermediate door (20).

The passage units 10 are installed in units of a predetermined length, and a plurality of the passage units may extend on the wall surface 5 and may be continuously installed, and the intermediate doors 20 may be provided between passage units adjacent to each other. Can be located.

In this case, the length of the passage unit 10 or the position of the intermediate door 20 may be variously designed.

The passage unit 10 refers to a state in which the foldable evacuation passage 1 is normally installed on the wall surface 5, and the foldable evacuation passage 1 will be described in detail with reference to the following drawings.

2 is a cross-sectional view showing a cross section of the foldable evacuation passage of FIG. 1. 3 is a perspective view showing a state in which the folding evacuation passage of FIG. 1 is fixed to a wall surface. FIG. 4 is a perspective view showing an internal structure excluding a screen in a state in which the folding evacuation passage of FIG. 1 is unfolded. 5 is a perspective view showing a state in which the folding evacuation passage of FIG. 1 is unfolded. 6 is a perspective view showing an evacuation passage in a state in which the foldable evacuation passage of FIG. 1 is unfolded. 7 is a side view of the folding evacuation passage of FIG. 1 as viewed from the outside.

2 to 7, the folding evacuation passage 1 is a box part 100, a fixed frame 200, a connection frame 300, a folding frame 400, a holder frame 500, a rotating frame ( 600), an upper screen 700, a vertical screen 800 and a wire 900.

The box part 100 forms a storage space 101 therein, and in the storage space 101, all components of the foldable evacuation passage 1 except for the intermediate door 20 are normally Located.

In this case, the box portion 100 may have, for example, a quadrangular cross-section, and may have one side fixed to the wall surface 5, and may have various cross-sectional shapes.

In addition, the box portion 100 corresponds to the outer surface of the passage unit 10 shown in FIG. 1.

Meanwhile, in an emergency, the box part 100 may be removed to the outside, and a structure for removing the box part 100 is not limited.

The fixed frame 200 extends along the wall surface 5, and an air supply passage is formed therein. In this case, if the fixed frame 200 has a structure in which the air supply passage 201 is formed therein, the shape of the cross section may be variously formed, and may have a rectangular shape as shown.

In this case, although not shown, the air supply passage 201 may be connected to a separate air supply unit to receive air therein.

In addition, a plurality of exhaust portions 202 may be formed on one side of the fixing frame 200, for example, as shown in FIG. 3.

Thus, in an emergency, fresh air provided from the outside through the air supply passage 201 is supplied to the evacuation passage 7 formed by the foldable evacuation passage 1 through the exhaust portions 202, and thus the evacuation Positive pressure is formed in the passage 7 to prevent entry of dangerous substances such as smoke from fire from the outside of the evacuation passage 7.

That is, in the case of this embodiment, by omitting a separate air supply pipe for supplying the air, and using the inside of the fixed frame for fixing the components as a supply pipe, the installation cost and installation space by omitting a separate structure Can be reduced.

The connection frame 300 is fixed to one surface of the fixing frame 200, for example, a surface facing the wall surface 5, and fixes the folding frame 400.

The connection frame 300 may include an inclined angle fixing pin 310, and one end of the folding frame 400 may be fixed through the inclined angle fixing pin 310.

Meanwhile, a moving space 320 is formed in the connection frame 300, and the moving space 320 may be formed to have a predetermined curvature. Thus, the inclined angle fixing pin 310 may be guided and moved along the movement space 320.

That is, the inclined angle fixing pin 310 for fixing the folding frame 400 may be positioned and fixed at an arbitrary position on the moving space 320, and through this, a predetermined with respect to the connection frame 300 It is possible to variously change the extension angle of the folding frame 400 extending while forming an angle of.

In this way, by changing the angle formed by the folding frame 400 with respect to the connection frame 300, the inclination angle of the upper surface of the evacuation passage 7 changes, and accordingly, the width of the evacuation passage 7 It can be variable.

Furthermore, since the lowering speed of the upper screen 700 to be described later may be changed according to the direction in which the folding frame 400 extends, that is, the degree of oblique extension, the extension of the folding frame 400 in consideration of this You can also change the angle in various ways.

The folding frame 400 is unfolded as shown in FIG. 4 in an emergency from the folded state of FIG. 2 in a normal manner with a mechanism similar to that of bending and unfolding the arm.

In this case, a plurality of the folding frames 400 are fixed to the fixing frame 200 through the connection frame 300, and accordingly, the plurality of folding frames 400 are simultaneously unfolded in an emergency.

The folding frame 400 includes a first joint part 410, a first extension part 420, a second joint part 430, and a second extension part 440.

The first joint part 410 is connected to the inclined angle fixing pin 310 of the connection frame 300, and the first extension part 420 is directed toward the fixing frame 200 by the first joint part 410. It is located so as to be close to (usually), and then unfolds in a direction perpendicular to the fixed frame 200 (in an emergency).

In this case, the first extension part 420 has a bar shape and extends a predetermined length.

The second joint part 430 is connected between the first extension part 420 and the second extension part 440, and the first and second extension parts 420 and 440 are relatively folded. Let it unfold.

In this case, the second extension part 440 also has a bar shape and is elongated to a predetermined length.

Thus, in normal times, the first extension part 420 and the second extension part 440 are folded to be adjacent to the fixed frame 200 while overlapping each other, but in an emergency, the first extension part ( 420 and the second extension part 440 are spread in a direction perpendicular to the fixed frame 200 to form a frame on the upper surface of the evacuation passage 7.

The holder frame 500 is fixed to the end of the second extension part 440 of the folding frame 400 and forms a holder space 501 therein.

As the folding frame 400 is unfolded in an emergency, the holder frame 500 is moved away from the fixed frame 200 from a position close to the fixed frame 200 in a normal time as shown in FIG. 2. Accordingly, the end of the upper surface of the evacuation passage 7 is formed.

In addition, an end 701 of the upper screen 700 is fixed to one side of the holder frame 500, that is, one side of the upper side, and an upper end of the vertical screen 800 is provided on a lower surface of the holder frame 500. 801 is fixed.

Thus, as the holder frame 500 moves away from the fixed frame 200, the upper screen 700 also has the end 701 away from the fixed frame 200, and naturally, the upper screen 700 Will unfold.

In this case, the upper screen 700 and the vertical screen 800 are connected to each other by the wire 900, and the downward direction of the upper screen 700 and the downward direction of the vertical screen 800 are Therefore, it is necessary to change the direction of extension of the wire 900.

Accordingly, the holder frame 500 includes a switching unit 510 in the holding space 501 so that the extension direction of the wire 900 is switched.

That is, the conversion part 510 has a cylindrical bar shape that extends in a longitudinal direction, and a wire contacts and extends to a part of the outer circumferential surface. As shown in FIG. 2, the upper screen 700 is in a diagonal direction. ), the wire 900 extends through the contact with the switching unit 510 and is changed in a downward direction, and extends through the vertical screen 800.

The rotation frame 600 is fixed to one surface, for example, an upper surface of the fixing frame 200, and first and second fixing parts 610 and 620, a rotation bar 630 and a pulley part 640 ).

The first and second fixing parts 610 and 620 correspond to both ends of the rotation frame 600, respectively, and both ends of the rotation bar 630 are respectively the first and second fixing parts ( 610, 620).

The rotating bar 630 is naturally rotatable with respect to the first and second fixing parts 610 and 620 even if a separate driving force is not provided, and is normally locked to a separate fixing device, although not shown. ) Is not rotated.

However, in an emergency, the fixing device is released, and accordingly, the rotation bar 630 rotates when an external force is applied.

A plurality of the pulley parts 640 are fixed to the rotation bar 630 and rotate together with the rotation of the rotation bar 630.

In this case, the wire 900 is wound around the pulley part 640, and the wire 900 is positioned in a state wound around the pulley part 640 because the rotating bar 630 does not rotate in normal times. It is done.

However, in an emergency, when the fixing device for the rotation bar 630 is released, the pulley part 640 rotates together with the rotation bar 630 by its own weight acting on the wire 900, and thus Accordingly, the wire 900 is continuously released from the pulley portion 640 as long as its own weight acts.

The upper screen 700, as described above, the end 701 is fixed to the holder frame 500, one end 702 is connected to the rotating frame 600, the rotating frame 600 An upper cover part 710 for protecting or covering the upper screen 700 may be interposed between the and.

As shown, the upper screen 700 has a wrinkle shape and is located in a folded state in normal times, but in an emergency, the folds that were folded are unfolded and the length is extended.

In this way, when the upper screen 700 is expanded, the upper surface of the evacuation passage 7 is formed.

In this case, the wire 900 penetrates the upper screen 700 in a normal state and is wound around the pulley part 640, and the wire 900 starts to be unwound from the pulley part 640 in an emergency. While the upper screen 700 is uniformly spread along the extension direction of the wire 900, the length is extended.

On the other hand, the upper screen 700 has been described by illustrating that it has a corrugated shape, but may be in the form of a roll screen, and if the upper screen 700 is a roll screen, the upper screen 700 is the rotating bar 610 ) Can be rolled directly on the outer circumferential surface and unfolded from the wound state.

As for the vertical screen 800, as described above, the upper end 801 is fixed to the lower surface of the holder frame 500, and the load unit 810 is fixed to the lower end 802.

The vertical screen 800 also has the same wrinkle shape as the upper screen 700 and is located in a folded state in normal times, but in an emergency, the folded wrinkle is spread and its length is extended.

In this way, when the vertical screen 800 is expanded, a side surface of the evacuation passage 7 is formed.

In addition, in the present embodiment, the vertical screen 800 may have a rectangular shape as a whole, as shown in FIG. 7 when all of the vertical screens 800 are unfolded.

In this case, the wire 900 penetrates the vertical screen 800 in normal times, and in an emergency, the wire 900 starts to be unwound from the pulley part 640, and the vertical screen 800 also passes through the wire ( 900) is spread uniformly along the extension direction and the length is extended.

At this time, the wire 900 extends diagonally through the switching unit 510 and then extends in a vertical direction, and the vertical screen 800 is connected by a wire 900 extending in the vertical direction. , The vertical screen 800 is unfolded in a vertical direction.

On the other hand, the wire 900 is released from the pulley part 640 while the rotation bar 630 starts to rotate as the fixing device that fixed the rotation of the rotation bar 630 is released. In this case, the wire A predetermined load is to be applied to (900).

Accordingly, the load unit 810 fixed to the lower portion of the vertical screen 800 applies a predetermined load to the vertical screen 800 and the upper screen 700, as well as the wire 900 connecting them. Therefore, as the fixing device of the rotating bar 630 is released, the wire 900 is released from the pulley part 640.

Meanwhile, in order to more stably fix and connect the vertical screen 800 and the upper screen 700, a plurality of the wires 900 may be formed to be spaced apart from each other by a predetermined distance, and accordingly, the pulley part ( A plurality of 640 may also be formed to be spaced apart from each other by a predetermined distance.

Meanwhile, as shown in FIG. 1, the intermediate door 20 is fixed to the wall surface 5 in normal times, and is positioned so that the door is disposed parallel to the extending direction of the wall surface 5. As shown in FIG. 6, in an emergency, it is rotated from the wall surface 5 and the door is positioned to face a direction perpendicular to the extending direction of the wall surface 5.

Thus, the intermediate door 20 is positioned in a direction perpendicular to the evacuation passage 7, as in FIG. 6, and the evacuee passes through the evacuation passage 7 and passes the intermediate door 20 It moves while opening and closing.

In this way, as the intermediate door 20 is located in the middle of the evacuation passage 7, even if smoke or fire flows into the evacuation passage 7 in a certain area, it is extended to the evacuation passage in the adjacent area. Can be blocked.

Meanwhile, a skirt 820 may be additionally formed at the lower end of the load part 810.

The skirt 820 extends along the extension direction of the load part 810, and further extends in the lower direction of the load part 810 by a predetermined length.

Thus, even if the load part 810 is located on the floor surface, a space that may be formed between the load part 810 and the floor surface may be more effectively sealed through the skirt 820.

In this case, the skirt 820 may be formed of a flexible material for effective sealing with the bottom surface.

On the other hand, in an emergency, even when the vertical screen 800 descends to seal the side of the evacuation passage 7, a cut-off portion 850 is formed between the vertical screens between the passage units 10 adjacent to each other. Can be.

Thus, the disconnection part 850 may be used as a so-called entrance door, and a refugee may enter the evacuation passage 7 through the entrance door.

Furthermore, a predetermined display unit 21 may be displayed on the outer surface of the vertical screen 800 at all times so that the disconnection unit 850 can be easily identified from the outside, and through this, an evacuation direction can be easily provided to the evacuee. can do.

8 is a conceptual diagram observing from the outside a state in which the folding evacuation passage according to another embodiment of the present invention is unfolded.

However, in FIG. 8, only the holder frame 500 and the vertical screen 800 are illustrated for convenience of description.

The foldable evacuation passage 2 in this embodiment is substantially the same as the foldable evacuation passage 1 described with reference to FIGS. 1 to 7 except for the unfolding shape of the vertical screen, so the same for the same components Reference numbers are used and duplicate descriptions are omitted.

When the floor surface is a flat surface, an evacuation passage 7 may be formed with the foldable evacuation passage 1 described above, but if the floor surface is inclined, or if it is the same as a floor on which stairs are formed, the previously described foldable The evacuation passage 1 cannot effectively seal the space between the load part or the skirt and the floor surface.

Thus, as shown in FIG. 8, using the foldable evacuation passage 2 in this embodiment, the bottom surface extends in a direction (A) inclined by a predetermined angle (a) with respect to the extension direction (X) of the plane. Even if it is, it is possible to form the evacuation passage 7 while effectively sealing the space between the floor surfaces.

That is, when the vertical screen 800 is unfolded, as a whole, it is unfolded to have a parallelogram shape, not a rectangular shape, so that the lower end 802 of the vertical screen 800 is an inclined direction (A) of the inclined surface. It can be extended along.

In this case, the holder frame 500 may be fixed on the wall surface 5 in a direction parallel to the inclined direction A, and the extension direction of the lower end 802 of the vertical screen 800 is It may extend in a direction parallel to the extension direction of the holder frame 500.

Meanwhile, since the holder frame 500 eventually extends in the same direction as the extension direction of the fixed frame 200 and the passage unit 10, the extension direction of the lower end 802 of the vertical screen 800 is It is substantially the same as the direction in which the passage unit 10 extends.

To this end, the vertical screen 800 is positioned so that the start of the upper end 801 coincides with the start 501 of the holder frame 500, but the start of the lower 802 is It is located spaced apart from the start part 501 by a predetermined distance (B).

Thus, the end of the upper end 801 of the vertical screen 800 is positioned to coincide with the end 502 of the holder frame 500, but the end of the lower end 802 is the end 502 of the holder frame 500 ) Is spaced apart by a predetermined distance (B).

Since the vertical screen 800 is extended in such a shape and arrangement, the lower end of the vertical screen 800 can effectively seal the space between the bottom surface and the bottom surface even when the bottom surface has a predetermined inclination.

Further, as the vertical screen 800 extends in the shape and arrangement as described above, when the vertical screen 800 is disposed along an inclined surface, one end extends obliquely by gravity, and the extended portion is adjacent It is possible to solve the problem of overlapping or non-uniform connection between vertical screens, such as overlapping with the vertical screen 800.

That is, when the vertical screen 800 is disposed along an inclined surface, even if one end of the vertical screen on the upper side extends obliquely toward the vertical screen on the lower side, they are not overlapped or unevenly connected to each other, so that the space can be more effectively sealed. do.

9 is a conceptual diagram observing from the outside a state in which the folding evacuation passage is unfolded according to another embodiment of the present invention.

However, in FIG. 9, for convenience of explanation, only a part of the rotating frame 600, the upper screen 700, the holder frame 500, and the vertical screen 800 are illustrated.

The foldable evacuation passage 3 in this embodiment is substantially the same as the foldable evacuation passage 1 described with reference to FIGS. 1 to 7 except for the unfolding shape of the vertical screen, so for the same components Reference numbers are used and duplicate descriptions are omitted.

If the floor surface is a flat or inclined surface, an evacuation passage 7 may be formed with the foldable evacuation passages 1 and 2 described above, but a predetermined depression or height on the flat or inclined floor surface If there are other sections, the space cannot be effectively sealed with the foldable evacuation passages (1, 2) described above.

Accordingly, the foldable evacuation passage 3 in the present embodiment shown in FIG. 9 further includes an expansion screen 860 and related components, thereby effectively sealing the depressions or sections having different heights as described above. You will be able to do it.

That is, referring to FIG. 9, in the foldable evacuation passage 3 in this embodiment, the pulley portion 650 further includes an expansion pulley 652 in addition to the pulley 651, and expands in addition to the wire 900 It further includes a wire 901, and further includes the expansion screen 860, the expansion load unit 811, and the expansion skirt 821.

In the foldable evacuation passage 3, the expansion screen 860 is additionally provided in a certain area (ie, a certain section) of the vertical screen 800 of the foldable evacuation passage 1 described with reference to FIGS. 1 to 7 It is characterized by being.

In this case, the area or section in which the expansion screen 860 is provided may be variously changed in consideration of the length or area of a section having a different height or a depression formed on the bottom surface. Although it is illustrated that only one extended screen 860 is formed, a plurality of the extended screens may have different lengths.

The expansion screen 860 has a structure in which a corrugated screen is unfolded in the same manner as the vertical screen 800, and the expansion load part 811 is formed at the lower end, and the expansion screen 860 is also The descent becomes possible.

In addition, the expansion skirt 821 is formed on the lower surface of the expansion load part 811, so that the space between the expansion load part 811 and the floor surface may be more effectively sealed.

In this case, as described above, the expansion skirt 821 may be a flexible material.

Meanwhile, the extended screen 860 and the vertical screen 800 and the upper screen 700 positioned above the extended screen 860 are extended wires 901 different from the wires 900 described in FIG. 1. Are connected to each other through

That is, since the length extended as a whole is increased by the expansion screen 860, a wire longer than the other wires 900 should be applied to the expansion wire 901.

Furthermore, since the expansion screen 860 must be additionally expanded even after all the vertical screens 800 in adjacent positions are expanded, the expansion pulley 652 wound around the expansion wire 901 connecting the expansion screen 860 is wound. ), should be capable of additional rotation than other pulleys 651.

Thus, the expansion screen 860 is additionally expanded in the recessed portion or in a section having a different height, so that it is possible to perform sealing while minimizing the space between the floor surface and the fire or smoke, the evacuation passage (7) It can minimize the inflow into.

According to the embodiments of the present invention, while minimizing the space occupied by the folding evacuation passage in normal times, it is possible to form an evacuation passage with sufficient space for evacuation in case of an emergency, so that it is easy to install and secure space. And, it is possible to improve usability, convenience, and user safety.

In particular, it is necessary to continuously inject fresh air into the evacuation passage in case of an emergency, and by solving the problem of having to separately install such an air injection structure in the past, the inside of the fixed frame, which is an essential structure of the folding evacuation passage, is used as the supply passage. , By forming the exhaust parts in the fixed frame, it is possible to perform air injection while improving space usability.

In addition, by forming a structure in which the folding frame is folded and unfolded, the upper screen is naturally unfolded in an emergency and can form the upper surface of the evacuation passage. In this case, the upper screen is lowered obliquely by its own weight without providing a separate driving force. However, the downward direction may be controlled by the folding frame.

In addition, in the case of a vertical screen, it is possible to descend in a vertical direction by its own weight without providing a driving force of a separate driving unit. Accordingly, the driving unit can be omitted, thereby simplifying the structure of the evacuation passage.

In this case, the upper screen and the vertical screen have a structure in which the fixed wire is released from the fixed state and descends with the wire, and an effective lowering structure can be implemented with a simple structure, and by controlling the rotation speed of the rotating bar through the speed control unit By descending at an excessively high speed, problems such as injuries of a refugee can be prevented in advance.

Further, by adjusting the extension angle of the folding frame, the inclination angle of the upper surface of the evacuation space can be adjusted, the size of the evacuation space can be changed, and the lowering speed of the upper screen can be changed.

In addition, by forming a load portion under the vertical screen, it is possible to naturally induce a descent due to its own weight in the vertical direction, and a skirt may be additionally provided to seal the space between the lower part of the vertical screen and the floor.

In addition, by varying the starting positions of the upper and lower ends so that the vertical screen is unfolded in a rectangular shape and unfolded in a parallelogram shape, the foldable evacuation passage is installed in a space where the floor is parallel, and the floor is inclined. It can also be installed in a space, especially an inclined space where stairs are installed.

In particular, by forming an expansion screen that extends further downward than the bottom of the vertical screen in a partial area of the vertical screen, when a staircase is installed on the floor or a separate recessed space is formed, the corresponding space can be more effectively sealed. have.

Although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the present invention described in the following claims.
