Description

Life breathing apparatus for elevators {Breathing Equipment for Elevator}

The present invention relates to a life-saving breathing apparatus for an elevator, and more particularly, in order to evacuate an elevator occupant without difficulty in breathing and suffocating in the event of a disaster in the elevator, such as fumes caused by a fire or toxic gas flowed into the elevator. To provide a life-saving breathing apparatus for the elevator.

To prevent the elevator occupants from breathing, or asphyxiation in the event of a fire, toxic gas leak, or terrorism or a firefighting disaster in an elevator, the elevator occupants can breathe while evacuating to the safety floor. It is important to provide a breathing function.

In recent years, the loss of life due to the use of elevators in the event of a fire, such as the occurrence of valuable life loss due to the use of elevators at a fire site in an apartment, has been continuously occurring, and this trend is similar in Korea as well as abroad. .

The elevator is basically not a sealed structure and air is circulated throughout the floor, thus acting as a chimney of the building in case of fire. Therefore, there is a problem that can be asphyxiated by being trapped in the smoke when riding the elevator when a fire occurs.

Sometimes it's shocking to see someone smothering in an elevator next to the building instead of a wildly lit site.

Therefore, most countries never use elevators in high-rise buildings in case of fire. However, it was reported that during the 1993 New York World Trade Center bombing, a very healthy person took an hour to walk down the stairs from the 95th floor to the first floor. There is a need to provide such a plan.

Recently, the atmosphere to use a lift in an emergency situation is spreading further. Despite this, the prior art is to install a temperature sensor for each floor to alert the voice warning when the temperature exceeds the reference value to protect passengers and firefighters life (1019980074061).

The present invention was devised as a new concept by the necessity as described above, in order to prevent the elevator occupant's breathing difficulties, asphyxiation in the event of a disaster in the elevator, such as fire mist, toxic gas or the like flow into the elevator. It aims to provide a breathing function that allows the lift occupant to breathe while escaping to the floor, and also provides an active and quick way to provide breathing function so that the occupant can be easily and quickly worn and safely in emergency and emergency situations. To provide a life-saving breathing apparatus for the elevator to evacuate.

In addition, the present invention allows the occupant to breathe by simply discharging the breathing air with a single touch (one touch), and also to keep the pressure in the breathing space to maintain a positive pressure breathing with fresh air while preventing the influx of external toxic gases To provide a life-saving breathing apparatus for the elevator to be able to.

In addition, the present invention includes an identification means that can be easily found and used in the event of a power outage, and also includes a lighting means that provides brightness, and further comprising a sensing means for detecting whether the elevator occupant uses the life-saving breathing apparatus and the number of uses. In addition, it is also intended to provide a life-saving breathing apparatus for an elevator including a useful additional function such as built-in battery to operate in the event of a power outage.

Therefore, when the disaster situation, the mask unit 400 is automatically distributed from the installation space 11 to the elevator boarding space 10, the elevator occupant can easily and quickly obtain and use the mask unit 400 have.

In particular, the life-saving breathing apparatus for an elevator of the present invention has various structures that allow the user to safely and easily breathe oxygen, and also maximize the speed and convenience of the user. Hereinafter, each part will be described in more detail.

The oxygen receiving unit 1000 is a compressed oxygen container accommodated in the compressed oxygen container 100, the compressed oxygen container 100, as shown in the oxygen receiving pressure of higher than atmospheric pressure to form a high-pressure space (V1). (100), the compressed oxygen container 100 is formed in a portion in communication with the outside to distribute the control valve 200 and the oxygen discharge to control the amount of opening and closing oxygen to one connection hose, or a plurality of connection hoses And a dispenser 250, which may be used.

At this time, the compressed oxygen container 100 is formed of a high rigidity, such as a metal material such as aluminum, to withstand high pressure in order to stably receive the oxygen at high pressure to receive the oxygen. In the high pressure space (V1) formed inside the compressed oxygen container 100, oxygen is compressed and stored to have a pressure of several tens to hundreds of times higher than atmospheric pressure, and thus, even if the size of the compressed oxygen container 100 is small, a considerable amount (That is, an amount that the user can hold for a very long time) can be stored. Here, since the substance necessary for human breathing is oxygen basically, the term 'oxygen' is used such as 'oxygen accommodating part' and 'compressed oxygen container' (hereinafter, referred to as 'oxygen'). Of course, the gas filled in the compressed oxygen container 100 may be pure oxygen or compressed air. In addition, the compressed oxygen container 100 may be any type as long as it can supply oxygen, and the compressed oxygen container 100 may include liquefied oxygen, liquefied air, or an oxygen generator. As such, the structure of the compressed oxygen container 100 may be modified in various ways without departing from the gist of the present invention.

The control valve 1 (200) is to adjust the discharge of the oxygen discharged from the compressed oxygen container 100, it may be made so that the user can adjust the opening or closing degree manually and automatically. As such, the structure of the control valve capable of performing opening and closing and / or discharge control in fluid distribution is variously known, and any configuration may be applied thereto, and the present invention is not limited to the structure of the control valve employed. If not, a detailed description of the structure will be omitted.

However, since the compressed oxygen container 100 is oxygen at high pressure, a risk such as explosion may occur under high pressure or high temperature even when stored or in use. Therefore, the control valve 1 (200) may have a function of the high-pressure high-temperature safety device 240 to automatically outflow some or all of the oxygen at a predetermined pressure or above a certain temperature. In addition, the compressed oxygen container 100 is made of a fixing device 12 that locks so as to prevent any movement in the installation space 11 of the upper portion of the elevator.

Next, the mask part 400 is formed on one side of the mask part case 121 and one side of the mask part case 121 to be in close contact with the user's face, and is formed inside the face contact part 122. The space is separated into the inner space of the buffer space (V2) and the breathing space (V3) of the face contact portion 122 side, a plurality of air so that air can flow between the buffer space (V2) and the breathing space (V3) Partitions 123 in which two through holes 123a are formed, and are formed at a position between the face contact portion 122 and the partitions 123 on the mask part case 121 so that the internal air is discharged to the outside and the external air is It is made to include a check valve 401 to prevent the inflow. In addition, the mask unit 400 is composed of a main body 480, a cap 470, the operation lever is removed by one touch (one touch) by the user to pull the main body 480 and the cap 470 As the breathing air is supplied, or the RFID tag 123 is operated, the spotlight 126 is activated, the emergency sound 125 is activated, or the oxygen amount sensor 124 may be operated.

The face contact portion 122 is made of rubber or silicon having elasticity and ductility. That is, the mask part 400 is basically formed in the mask part case 121 in a form separated into a buffer space (V2) and a breathing space (V3). As will be described in more detail below, in the present invention, the breathing space (V3) is formed to have a pressure slightly higher than atmospheric pressure (that is, formed to be positive pressure), even if the face contact portion 122 and the user's face Even if there is a minute gap therebetween, it is possible to prevent the outside air from flowing into the inside because the force in which the air in the breathing space V3 is forced out by the positive pressure is stronger.

The user substantially breathes his nose and mouth in the breathing space (V3), when the breathing out of the breathing space (V3) increases the pressure in the breathing space (V3) to the breathing space (V3) My pressure may not be stable. In addition, there may be a problem that the ratio of carbon dioxide contained in the exhalation in the breathing space (V3) becomes high. The check valve 401 is provided to eliminate such a problem, and when the internal pressure rises above a certain level due to the exhalation of the user in the breathing space (V3) by discharging the internal air to the outside, oxygen is continuously and It can be stably introduced into the breathing space (V3). Of course, the check valve 401 prevents the user from inhaling smoke or toxic substances by blocking external air from flowing into the inside. As such, the structure of the check valve for circulating the fluid only in one direction has also been known in various ways, and any of these structures may be employed, and the present invention is not limited according to the structure.

At this time, the mask unit 400 may be further provided with a breath discharge pipe 410 is connected to the check valve 401 and formed so that the user can bite. The increase in pressure due to the exhalation of the user by the breath discharge pipe 410 is directly transmitted to the check valve 401, whereby the carbon dioxide can be discharged more effectively.

The connection hose part 300 connects the high pressure space V1 and the breathing space V3 to supply oxygen to the mask part 400 from the oxygen receiving part 1000. At this time, the inside of the high pressure space (V1) has a pressure considerably higher than atmospheric pressure, if the high-pressure oxygen is directly introduced into the breathing space (V3) there may be a problem that the user is difficult to breathe. In other words, a person may have difficulty in inhaling oxygen because he or she is adapted to breathe at atmospheric pressure, and there is also a concern that excessive oxygen is inhaled at a time, causing symptoms of hyperventilation.

In order to prevent such a problem, the life-saving breathing apparatus for the elevator of the present invention reduces the pressure of oxygen supplied by allowing the buffer space V2 to be formed in the mask part 400 and then the through hole formed in the partition wall 123. This problem is prevented by reducing the pressure once more in the course of passing oxygen through the air passage 123a (V3). (Of course, by adjusting the control valve 2 402, the pressure of oxygen introduced into the buffer space V2 can be significantly reduced first. Here, the breathing space due to the presence of the buffer space V2. It is possible to easily maintain the pressure in (V3) at a pressure suitable for breathing.)

That is, to summarize the magnitude of the pressure, the pressure P (V1) in the high pressure space V1> the pressure P (V2) in the buffer space V2> the pressure P (V3) in the breathing space V3 )), It appears like this. Due to this pressure difference, in the elevator life-saving breathing apparatus of the present invention, the sequential oxygen supply in the order of the high pressure space (V1)-the buffer space (V2)-the breathing space (V3) in order to provide a device such as an active pump at all It can be done very naturally without the need. In addition, the pressure in the breathing space (V3) is preferably set to a slightly higher than the atmospheric pressure, by doing so, the user wears a little wrong so that the face contact portion 122 is not completely in contact with the face and a slight gap occurs. Even if the pressure difference can prevent the outside air to enter the breathing space (V3).

As described above, according to the present invention, since the user breathes oxygen in the oxygen accommodating part 1000, the user may breathe polluted air because the conventional gas mask does not completely filter out toxic substances from the filter. Problems that were more likely to be done can be ruled out.

In addition, the mask part 400 is provided in the partition wall 123 so as to open or close a part of the plurality of through holes 123a according to the pressure difference between the buffer space V2 and the breathing space V3. The discharge control device 403 may be further provided.

The pressure in the breathing space (V3) may be maintained at an appropriate pressure of 1.01 to 1.5 atm, slightly higher than the atmospheric pressure (1 atm). (Herein, the lower limit value is 1.01 atm, which is merely to indicate that it is higher than atmospheric pressure. In fact, the lower limit of the pressure in the breathing space V3 only needs to be larger than the atmospheric pressure of 1 atm.) The situation where the elevator life-saving breathing apparatus is used is when a disaster occurs.In the early stage, the user is urgently breathed instead of the usual calm breathing, and after a while, the user gradually breathes to some extent. . In consideration of this condition, when the user inhales hard, the amount of oxygen can be increased into the breathing space V3, i.e., the pressure higher than the proper atmospheric pressure described above. When the oxygen is introduced and the user inhales weakly, the oxygen discharge is controlled so that the amount of oxygen is introduced to the breathing space (V3) to maintain the above-mentioned proper atmospheric pressure.

Accordingly, in the present invention, as shown in FIG. 6, the mask part 400 is provided in the partition wall 123 and is provided in plural according to the pressure difference between the buffer space V2 and the breathing space V3. A discharge control device 403 is formed to further open or close a part of the through hole (123a). In other words, the discharge control device 403, when the user inhales hard breaths to increase the amount of oxygen discharged from the buffer space (V2) to the breathing space (V3), the user breathes weakly In this case, the amount of oxygen discharged from the buffer space V2 to the breathing space V3 becomes smaller.

As an embodiment of the discharge control device 403, the following structure can be presented. The discharge control device 403 is formed in the form of a film made of a flexible material having an elasticity, including silicon, a portion of the through-hole 123a opened when exhaled and exhaled by the user inhaled It is made to close. In this case, when the user's breathing force overcomes the elasticity of the membrane, the membrane is flipped to open some of the through holes 123a, which are closed by the membrane, thereby increasing oxygen emissions. When the user's breathing is stabilized, the power to inhale is reduced, and thus, when the user's breathing force does not overcome the elasticity of the membrane, the closed state of some of the through holes 123a, which are closed by the membrane, is maintained. Accordingly, only oxygen enough to maintain an appropriate atmospheric pressure from the buffer space V2 is discharged to the breathing space V3.

Of course, this is only one embodiment, and thus the present invention is not limited thereto. As described above, the discharge control device 403 may have any other form as long as it is a means for adjusting oxygen emission according to the breathing intensity of the user. It may be done.

The structure of the life-saving breathing apparatus for an elevator of this invention can be comprised as follows. When the face contact portion 122 is formed directly on the control valve 2 402, it may be inconvenient due to the weight of the control valve 2 402 when the mask unit 400 is worn. By configuring the control valve 2 (402) without, it is possible to minimize the weight of the part actually worn on the face.

In summary, the life-saving breathing apparatus for the elevator of the present invention is to be filled with oxygen in the oxygen receiving portion 1000, and from the oxygen receiving portion 1000 to the mask portion 400 through the connection hose portion 300. Oxygen is transported and supplied, and the face contact part 122 is formed on the mask part 400, that is, the part worn on the face of the person is made of only the mask part 400 which is relatively much lighter. It is configured to lose. Accordingly, the life-saving breathing apparatus for an elevator according to the present invention is free to move both hands after wearing even a simple structure such as a band, it is possible to maximize the user convenience in a disaster situation.

As described above, the mask part 400 may further include a mask part fixing means 128 that keeps the face contact part 122 in close contact with the user's face. The face wearing means may be implemented in the form of a fixing band that is fixed to the head of the human body in a state connected to the mask portion 400.

In addition, in the present invention, it is preferable to provide a means for preventing toxic air or smoke from contacting the eyes, the skin of the face, the hair, or the like, resulting in skin rash or difficulty in securing a vision. To this end, it is preferable to further include a face protector 129 formed in a shape that can be written on the user's head in the mask part 400 such that the lower part is in close contact with the neck by writing to the user's head. . The disaster situation assumed in the present invention includes a fire bar, the face protector 129 is free to deform shape and to withstand a certain amount of heat while maintaining transparency so as not to obscure the field of view when worn on the head The basic form is made of a material such as polyimide, but may be made of a form coated with aluminum, silver, or the like. Accordingly, the face protector 129 can be folded to reduce the volume, so that the face protector 129 thus reduced in volume is placed in the space between the main body 480 and the cap 470 of the mask part 400. Can be.
