Description

One-touch tunnel type fire escape device {ONE-TOUCH TUNNEL TYPE ESCAPE DEVICE FROM A FIRE}

The present invention relates to a fire escape device that allows users to quickly escape from a building in the event of a fire.

More specifically, the present invention relates to a fire escape device that compensates for the disadvantages of conventional descending devices and tube tunnels so that users can more easily and safely escape from high-rise buildings in the event of a fire.

In the event of a fire accident, not only victims of burns but also victims of suffocation due to toxic gases, smoke, and fumes occur. Therefore, in the event of a fire, it is necessary to evacuate the building as quickly as possible.

If it is impossible to escape through the doorway due to problems such as flame, toxic gas, smoke, etc., escape through the window. For people on the lower floors of the first or second floor, it is possible to jump through a window, but for people on the third or higher floor, it is not easy to jump out of a building through a window.

In order to quickly escape people on high floors in the event of a fire, high-rise buildings are generally equipped with descending devices.

However, in the case of the descending device, it is not easy to wear and operate until it is mastered. In addition, in the case of a conventional descender, there is a limit in that the descending speed cannot be easily adjusted. In addition, since it is common that only one descending elevator is provided for each floor of a building, if there are several people on a high floor, it takes a lot of time for everyone to escape, so there is a problem that the so-called golden time can be missed.

To improve this, a tube tunnel type fire escape device has been proposed (Patent Document 2). The tube tunnel type fire escape device is composed of a long tube tunnel made of very thin and strong fiber fabric treated with flame retardancy. Normally, it is stored rolled up, and in case of fire, the entrance of the tube tunnel is tied to the balcony railing or window frame and combined, and the tube tunnel is suspended to the ground, and when an assistant additionally deploys and supports it at an angle on the ground, the user enters the entrance of the tube tunnel and gradually descends can land on the ground. However, in this method, an inclined deployment is possible only with an assistant on the ground.

Registered Patent Publication No. 10-2303988 (2021.09.27.0 notice) Publication No. 10-2017-0114872 (published on October 16, 2017)

The problem to be solved by the present invention is to provide a fire escape device that allows users to more easily and more safely escape out of the building in the event of a fire in a high-rise building.

In order to solve the above problems, a one-touch tunnel type fire escape device according to an embodiment of the present invention includes a tunnel body extending and contracting in a longitudinal direction; a fixed module installed at the entrance of the tunnel body; a plurality of ring-shaped supports installed on the tunnel body along the circumferential direction of the tunnel body; and an exit module installed at an outlet of the tunnel body, wherein at least a part of the tunnel body has a different distance between supporters on the upper side and between supporters on the lower side.

At a portion adjacent to the exit of the tunnel body, it is preferable that the distance between the supports on the upper side of the tunnel body far from the ground is shorter than the distance between the supports on the lower side of the tunnel body close to the ground.

As one moves toward the exit from a specific part of the tunnel body, the distance between the supports on the upper side can be gradually shortened.

In the tunnel body, in a folded state, a first part having a first diameter and a second part having a second diameter smaller than the first diameter are alternately repeated, and in a unfolded state, the diameter of the second part is the first diameter. , and the plurality of supports may be installed on the first part.

The fixing module may include at least two rod members coupled to both sides of the tunnel body entrance.

The rod member has a variable length, and a lower end may be in close contact with the floor.

The exit module may include a plurality of elastic bands covering the exit to prevent escape of the escapee.

The outlet module may include an air mat disposed on a floor surface.

The air mat may include a mat body disposed on the tunnel body, an impact sensor, and a compressed gas storage unit configured to store compressed gas and provide gas to the mat body in response to the impact sensor.

The air mat may include a mat body disposed on the tunnel body, an inflator including a percussion unit, and a compressed gas cartridge connected to the inflator and opened by the percussion unit to supply gas to the mat body.

The air mat may include a mat body disposed on the tunnel body, a filler disposed on the mat body, and a stopper for regulating air movement between the outside of the mat body and the inside of the mat body.

According to the one-touch tunnel type fire escape device according to the present invention, in the event of a fire, simply throw the tunnel body out of the window in a state where the fixing module is coupled to both sides of the tunnel body entrance and installed around the window, automatically by the load of the tunnel body As a result, a tunnel can be formed to the ground.

In particular, according to the one-touch tunnel type fire escape device according to the present invention, the distance between the support bodies on the upper side of the tunnel body and the distance between the support bodies on the lower side are configured differently, so that the tunnel body can be automatically developed inclined. Through this, the user can escape safely.

In addition, according to the one-touch tunnel type fire escape device according to the present invention, it is possible to prevent the user from being thrown out of the tunnel body by the exit module or from being injured such as abrasions or fractures.

Hereinafter, a one-touch tunnel type fire escape device according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

A tunnel-type fire escape device according to the present invention is largely composed of a tunnel body and a fixing module for fixing an entrance of the tunnel body. All or major parts of the fixed module are placed inside the building, such as inside a window, and the entrance of the tunnel body is fixed to the fixed module.

Figure 1 schematically shows an example of a tunnel body in a state of normal storage. Figure 2 shows an example of a tunnel body in a state deployed to the outside of a building.

The one-touch tunnel type fire escape device according to the present invention is for use in case of fire and includes a tunnel body 110.

In addition, referring to FIGS. 1 to 5, the one-touch tunnel type fire escape device according to the present invention maintains the shape of the fixing module 120 (FIG. 5) and the tunnel body 110 for fixing the tunnel body 110. It includes a plurality of ring-shaped supports (130, FIG. 2) and an exit module (150, FIG. 2) that allows users to get out of the tunnel body (110).

The tunnel body 110 includes an inlet 112 and an outlet 115, and is a part that forms a tunnel when deployed. The tunnel body 110 extends in the longitudinal direction by deployment in a folded state, and forms a tunnel when deployed. Tunnel body 110 may be a cloth material or a plastic material. Preferably, the inner and outer surfaces of the tunnel body 110 may be flame retardant.

The tunnel body 110 is usually stored in a packed state, for example, in a folded state, as shown in the example shown in FIG. 1, and deployed to the ground as shown in the example shown in FIG. 2 when used by a fire.

The cross-sectional shape of the tunnel body 110 may be a rectangle as shown in FIG. 1 (a), or may be circular as shown in FIG. 1 (b). It may be more advantageous for the tunnel body 110 to have a rectangular cross-sectional shape in terms of maximally reducing the possibility of the fire escape device escaping from the fixed module 120 by lengthening the coupling length with the fixed module 120. When the tunnel body is developed, the cross-sectional shape of the tunnel body 110 may be maintained by a plurality of ring-shaped supports 130 to be described later. Adjacent ring-shaped supports 130 may be coupled to each other by a second support 132 extending in the longitudinal direction of the tunnel body 110 . Therefore, even if a part of the tunnel body is damaged in an unexpected situation, the cross-sectional shape of the tunnel body can be maintained as much as possible, thereby improving user safety.

3 shows an example of a tunnel body in a state of being deployed to the outside of a building through a window. 4 shows another example of a tunnel body in a state of being deployed to the outside of a building through a window.

The tunnel body 110 may be deployed from the window 101 of the building in a form such as the example shown in FIG. 3, a form such as the example shown in FIG. 4, and various other forms, which, as described later, the tunnel body It can be achieved by making the spacing between the upper side and the lower side of the support body different. However, in any form, it is preferable that the exit module 150 touches the ground.

The fixing module 120 is installed at the entrance 112 of the tunnel body 110 and serves to fix the entrance of the tunnel module.

5 shows an example in which the tunnel body is installed on the window 101 using a fixing module.

The fixing module 120 may include at least two rod members coupled to both sides of the tunnel body entrance. In this case, the rod member and the tunnel body may be directly coupled.

For direct coupling between the rod member and the tunnel body, coupling parts may be formed on both sides of the inlet 112 of the tunnel body 110. Coupling parts on both sides of the entrance of the tunnel body may be in the form of a tunnel so that the bar member can penetrate in the vertical direction, like the connecting part of a stretcher.

As another example, a plurality of rings may be disposed at the edge of the entrance of the tunnel body so as to be respectively fastened to a plurality of hooks or rings disposed on the ring-shaped member of the fixing module. This structure will be described later with reference to FIGS. 10 to 16 .

The rod member is a length-variable type, for example, 2- to 3-step rods 120a, 120b, and 120c, and when in use, the lower end may be in close contact with the floor 102. Furthermore, the upper end may be in close contact with the ceiling 103 . A rubber cover 125 may be coupled to the top and bottom of the rod for close contact with the floor and ceiling. As the rod member, for example, a ceiling-floor contact type side support rod of a hanger stand may be used.

In order to further increase the fixing force of the bar member, a fixing means such as a bracket pre-installed on the wall around the window 101 may be added.

As another example, as a fixing module around a window, a ring-shaped member to which a plurality of hooks or rings are coupled is fixed in advance or during use, and a plurality of rings are disposed at the edge of the entrance of the tunnel body in response to this, fixing the module during use A coupling between the and the tunnel body may be made.

Normally, the tunnel body 110 and the fixing module are stored separately, and in the event of a fire, for example, rod members are inserted into both sides of the entrance of the tunnel body 110 and combined, and the rod members are attached to the wall around the window, and to the ceiling and floor. After fixing, since the fire escape device can be completed by simply throwing the tunnel body 110 out of the building, it is simpler to operate than the conventional descending machine, so anyone can install it quickly, and users cannot directly see the ground from high floors. can also reduce the fear of

A plurality of ring-shaped supports 130 are installed on the tunnel body 110 along the circumferential direction of the tunnel body 110 .

6A shows an example in which a plurality of ring-shaped supports are installed in the tunnel body. 6B shows another example in which a plurality of ring-shaped supports are installed in the tunnel body. 6C shows an example in which a plurality of ring-shaped supports as well as wire-shaped second supports are installed in the tunnel body.

Since the tunnel body 110 is made of cloth or plastic, there is a possibility that the tunnel body 110 may be damaged by the user's weight. However, when the plurality of ring-shaped supports 130 are reinforced in the tunnel body 110, the rigidity can be increased, so that damage to the tunnel body 110 can be prevented and the shape of the tunnel body 110 can be maintained.

The plurality of supports 130 may be made of a metal material such as steel or a nickel-chromium alloy, or a material such as carbon fiber or engineering plastic.

The shape of the plurality of supports 130 may be a shape corresponding to the cross-sectional shape of the tunnel body 110. For example, if the tunnel body 110 has a rectangular cross-sectional shape, the plurality of supports 130 may have a rectangular ring shape.

The plurality of ring-shaped supports 130 may have a structure that is separated from each other, as in the example shown in FIG. 6A. In addition, the plurality of ring-shaped supports 130 may have an integral structure as in the example shown in FIG. 6B, and in this case, may have a spiral or coil structure along the longitudinal direction of the tunnel body 110.

On the other hand, referring to Figure 6c, adjacent ring-shaped supporters 130 may be coupled to each other by the second supporter 132 extending in the longitudinal direction of the tunnel body (110). Therefore, even if a part of the tunnel body is damaged in an unexpected situation, the cross-sectional shape of the tunnel body can be maintained as much as possible, thereby improving user safety.

7 schematically shows an example of a tunnel body in a stored state and a deployed state.

For example, as shown in FIG. 7 , the tunnel body has a first portion 710 having a first diameter d1 in a folded state and a second diameter d2 smaller than the first diameter d1. The second part 720 may have an alternately repeated structure. Also, when the tunnel body is deployed, the diameter of the second portion 720 may expand to the first diameter d1. A plurality of supports 120 may be installed on the first portion 710 .

The exit module 150 is installed at the exit of the tunnel body. The exit module 150 may be to increase user safety.

In one embodiment, the exit module 150 has an exit ( 115) may include a plurality of elastic bands (810 in FIG. 8) disposed to cover the elastic bands.

Figure 8 schematically shows an example of an elastic band installed at the exit of the tunnel body.

Even if the user slides down to the exit 115 of the tunnel body 110 at high speed, the user does not bounce out of the tunnel body due to the elasticity of the elastic bands 810 .

On the other hand, the user can get out of the tunnel body 110 by spreading between the elastic bands 810 . As another example, a zipper (not shown) is placed near the exit 115, and the user can open the zipper to get out of the tunnel body 110, which means that the exit will be made of an air mat rather than a plurality of elastic bands. effective when

In another embodiment, the exit module 150 may include an air mat on the exit side to prevent a user who has slipped down from the tunnel body 110 from being injured such as abrasions or fractures due to friction or impact with the ground. there is. The air mat is disposed on the bottom surface, and may be additionally disposed on the side or top surface.

9 shows an example in which an air mat is installed at the exit side of the tunnel body.

The mat body constituting the air mat 910 is normally maintained in a minimum volume inside or outside the tunnel body. However, when a user drops the tunnel body from a high-rise building, the exit is hit on the ground by the weight of the tunnel body. At this time, the shock sensor detects the impact, and the inlet of the compressed gas storage unit is opened by explosion or movement, and accordingly, the compressed gas is supplied to the mat body to make an air mat.

The air mat 910 can operate on the same principle as the inflatable life jacket, and the known operating principle of the inflatable life jacket can be applied to the air mat of the exit module of the present invention as it is or with slight modifications.

For example, the air mat 910 includes a mat body disposed in a tunnel body, an inflator including a trigger, and a compressed gas cartridge connected to the inflator and opened by the trigger of the trigger to provide gas to the mat body. can include

Percussion may be carried out in a so-called rope pulling method using a wire and a rope as a percussion device. In the rope pulling method, as the tunnel body descends, the wire disposed in the exit module is spread, and a thin rope is connected between the wires, and then the wires are opened and the rope is pulled to operate.

As another example, the air mat may include a mat body disposed in the tunnel body, a filler disposed in the mat body, and a stopper for regulating air movement between the outside of the mat body and the inside of the mat body. This can be operated on a principle similar to the principle of a so-called automatic filling mat, vacuum compression pack for bedding, etc. In normal times, a filling material such as a sponge disposed inside the mat is in a compressed state, and when used, the filling material may be inflated as air is charged inside the mat. When the stopper is opened, the air inside the mat body is drawn out, and the stopper is closed again, the filling material inside the mat is compressed. When the cap is opened again, air is introduced into the mat body and the filling material is inflated accordingly to provide a cushion to the emma mat.

In the case of the present invention, in at least a part of the tunnel body 110, the distance L1 between the supports on the upper side and the distance L2 between the supports on the lower side are different. Here, the distance L1 between the supporters on the upper side and the distance L2 between the supports on the lower side mean the distance between one supporter and another adjacent supporter. Since the supports do not have to be arranged at equal intervals along the longitudinal direction of the tunnel body, the intervals L1 between the supports on the upper side may be different from each other along the length of the tunnel body 110), and the The spacing L2 between the supports may also be different from each other along the length of the tunnel body 110).

For example, if the distance L1 between the supports on the upper side is the same as the distance between the supports on the lower side, the tunnel body 110 will be developed at a constant inclination relative to the ground. On the other hand, if the distance between the supports on the upper side is smaller than the distance between the supports on the lower side, the tunnel body 110 will be developed in a form with a gentle slope relative to the ground. In addition, if the distance between the supports on the upper side is greater than the distance between the supports on the lower side, the tunnel body 110 will be developed in a form with an increased inclination relative to the ground. When the slope of the tunnel body 110 becomes gentle, it means that the speed of the escapee decreases, and when the slope of the tunnel body 110 increases, it means that the speed of the escapee increases.

In particular, in the portion adjacent to the exit 115 of the tunnel body 110, it is necessary to reduce the speed for the safety of the escapee. To this end, in order to make the slope gentle at the portion adjacent to the outlet 115 of the tunnel body 110, the distance L1 between the supports on the upper side should be shorter than the distance L2 between the supports on the lower side. can In this case, as in the example shown in FIG. 4, a section (A) in which the interval (L1) between the support bodies on the upper side is the same as the interval (L2) between the support bodies on the lower side until a specific part of the tunnel body 110 And, the interval (L1) between the supports on the upper side may be composed of a shorter section (B) than the interval (L2) between the supports on the lower side.

As another example, as in the example shown in FIG. 3, the distance between the support bodies on the upper side is shorter than the distance L2 between the support bodies on the lower side (A), the distance between the support bodies on the upper side A configuration in which there is a section (B) equal to the spacing between the supports on the lower side and a section (C) in which the spacing between the supporters on the upper side is longer than the spacing between the supports on the lower side can also be considered.

In addition, as the tunnel body 110 is directed toward the exit from a specific portion (eg, 2/3 point from the inlet), the distance L1 between the supports on the upper side may be gradually shortened. Through this, as the exit 115 of the tunnel body 110 is approached, the speed of the escapee gradually decreases, so that it can escape safely.

In the tunnel body 110, the difference between the distance L1 between the supports on the upper side and the distance L2 between the supports on the lower side is, for example, 5 to 20%, more preferably 5 to 10%. can If the difference between the distance between the supports on the upper side and the support on the lower side is too large, the deceleration effect can be maximized, but the user may stop in the middle of the tunnel body due to the increase in frictional force. Conversely, if the difference between the distance between the supports on the upper side and the distance between the supports on the lower side is too small, the deceleration effect may be too small.

As a method of shortening the distance between the supports, a method of overlapping and sewing (730 in FIG. 7) or bonding a part of the tunnel body between the supports may be used, among which, to prevent damage to the user during movement. In terms of the sewing method is more preferred.

In addition, the entrance side may be marked or marked to distinguish the upper side and the lower side so that the upper side and the lower side of the tunnel body can be clearly distinguished.

Through the above structure, in the event of a fire, simply throw the tunnel body out of the window in the state where the fixing module is coupled to both sides of the tunnel body entrance and installed around the window, and the tunnel is automatically formed to the ground by the load of the tunnel body It can be. In particular, according to the one-touch tunnel type fire escape device according to the present invention, the distance between the support bodies on the upper side of the tunnel body and the distance between the support bodies on the lower side are configured differently, so that the tunnel body can be automatically developed inclinedly, Users can safely escape to the outside of the building through the tunnel body.

In addition, according to the one-touch tunnel type fire escape device according to the present invention, it is possible to prevent the user from being thrown out of the tunnel body by the exit module or from being injured such as abrasions or fractures.

10 to 16 show other examples of fixing modules that can be used in the fire escape device according to the present invention.

10 to 16 , the fixing module according to the illustrated example includes a rod member 1110, a ring-shaped member 1120, and a plurality of hangers/rings 1130.

The rod member 1110 is a length-variable type, for example, two to three-stage rods 1110a, 1110b, and 1110c, and when in use, the lower end may be in close contact with the floor. For example, a pin/hole combination 1115 may be used to adjust the length of the rod member 1110, and an external pin may be used as the pin or a built-in rod member pin including a spring may be used. In addition, in order to increase the coupling force of the ring-shaped member 1120 and to suppress shaking of the rod member 1110 itself, a portion of the rod member 1110 (eg, 1110a in FIG. It may be extended in a horizontal direction so as to be connected.

The ring-shaped member 1120 may be coupled integrally or with a portion of the rod member through bonding.

The plurality of hangers/rings 1130 are integrally or bonded to the ring-shaped member 1120. The plurality of hooks/rings 1130 are parts for fastening with the tunnel body, and in order to fasten the plurality of hooks/rings 1130 and the tunnel body, a plurality of rings may be disposed at the edge of the entrance of the tunnel body.

In addition, referring to FIG. 10 , a scaffolding unit 1140 may be further included in the fixing module. The scaffolding portion 1140 allows the user to enter the tunnel body while stepping on the scaffolding portion. The footrest unit 1140 serves to increase the user's ease of escape, for example, when the height of the window is as high as about 1 m or more. Folding/unfolding of the scaffolding portion can be controlled through a hinge, and through this, an effect of substantially increasing the area of the scaffolding portion can be brought about during use. In addition, the height of the scaffolding portion 1140 may also be adjusted through a pin/hole combination or the like.

Also, referring to FIGS. 14 to 16 , the fixing module may further include foldable fixing devices 1210 and 1220 . The foldable fixing devices 1210 and 1220 are used to tightly fix the fixing module to a window frame or a wall of a building when in use. One member 1220 of the fixing device may have a variable position, and a rotational position may be fixed by a pin inserted into an insertion hole ( 1215 in FIG. 16 ) during use.
