BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a portable face protector for protecting a human being from poisonous gas and securing visibility, which can be used in an emergency such as a fire, etc.

2. Description of the Related Art

Generally, a gas mask is to protect a human life from a poisonous gas generated when a fire breaks out or a biochemical gas is spread in war or terrorism. The gas mask purifies the poisonous gas so that a human being can breathe.

Recently, due to frequent fires in a department store, a hotel, a theater, a transportation such as a bus, a subway, etc., the gas mask has attracted a lot of attention. Since a user can quickly wear the gas mask in an emergency such as a fire, etc., the gas mask is tending to have a simple structure. Thus, the gas mask can be used for only a desired time the user can escape from a critical region.

Meanwhile, since a conventional gas mask is considerably large and heavy and it is thus inconvenient for a general person to carry the gas mask, there is a problem that it is hard to facilely get the gas mask in the emergency. Furthermore, even if it is possible to get the gas mask in the emergency, there is another problem that it is hard for the general person, who is not trained, to rapidly wear the gas mask in the emergency. Therefore, it is urgently required to develop a gas mask that the general person can easily use and also facilely carry.

In addition, since the conventional gas mask is sold at a high price, it is too much for the government or a local autonomous entity to place a large quantity of gas masks in many public areas. Further, it will be also an economical burden on the general persons to individually buy the gas mask.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a portable face protector for protecting a human being from poisonous gas and securing visibility, which can be facilely carried and rapidly used in an emergency such as a fire, etc., so as to protect a human lift from the poisonous gas and safely escape from a critical region, and which can be also sold at a low price.

To achieve these and other advantages and in accordance with the purpose of the present invention, a portable face protector comprises a visibility securing member having a transparent window, for tightly covering a face around eyes of a user; and a cloth member for tightly covering the face around a mouth and a nose of the user so as to filter poisonous gas, wherein, in an emergency, the visibility securing member is air-tightly attached to the face around eyes so as to secure visibility of the user through the transparent window, and the cloth member is hold by a hand of the user so as to tightly cover the face around the mouth and nose, whereby the user can be protected from the poisonous gas and can safely escape from a critical region.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A portable face protector of the present invention is to protect a human being from poisonous gas and secure visibility, and comprises a first receiving portion and a second receiving portion20, as shown inFIGS. 1 to 5.

As shown inFIG. 1, the first receiving portion1receives a visibility securing member10therein.

In order to minimize an entire volume of the first receiving portion1, the visibility securing member10is folded a few times and then received in the first receiving portion1. Therefore, a user can conveniently carry the first receiving portion1in a small bag, a hand bag and a pocket.

The first receiving portion1is formed of vinyl and aluminum foil. The visibility securing member10can be withdrawn from the first receiving portion1after ripping a side of the first receiving portion1open using a detaching groove30.

The detaching groove30is formed at each end of both opposite sides of the first receiving portion1. Therefore, in an emergency, the user can easily rip one side of the vinyl or aluminum foil of the first receiving portion1and then withdraw the visibility securing member10.

As shown inFIGS. 1 to 3, the visibility securing member10comprises a pair of transparent windows11and an attaching portion12formed around each of the transparent windows11so as to be attached to a face.

The transparent windows11are symmetrically disposed at both sides of the visibility securing member10, and have an elliptical shape. Besides, the transparent windows11may have various shapes. For example, the transparent window may be formed into a single large window shape.

Further, the transparent windows11are convexed toward each from face thereof so as to form a concaved space therein.

The transparent window11may be formed of glass or synthetic resin like plastic. In case of the plastic, it is preferred that it has a high heat resistance which is higher than a temperature that a general person can endure.

Meanwhile, the shape of the transparent window11is not limited to a block structure as shown inFIGS. 1 to 3. The transparent window11may be formed to be planed or convexed at only a blade portion of a nose.

Preferably, the attaching portion12of the visibility securing member10is formed of cotton or non-woven fabric, and may be formed of paper, vinyl, plastic, silicon, etc., which can be excellently attached to the face.

One surface of the attaching portion12is an adhesive surface13.

The attaching portion12has a size that can cover the cheekbone and the blade portion of the nose from a forehead or glabella of the face.

A protecting paper14is covered on the adhesive surface13of the attaching portion12to prevent the adhesive surface13from being exposed to the outside.

The protecting paper14has a separating portion15at a side thereof so as to be facilely separated from the adhesive surface13of the attaching portion12.

That is, in the emergency, a user rapidly peels off the protecting paper14from the attaching portion12using the separating portion15.

The visibility securing member10is standardized into a small size, a middle size and a large size, so that the user can choose a proper size of the visibility securing member10according to a size of the user's face.

Meanwhile, as shown inFIGS. 4 and 5, the second receiving portion20receives a cloth member22therein.

In order to minimize an entire volume of the second receiving portion20, the cloth member22is folded a few times and then received in the second receiving portion20.

This is for the user to conveniently carry the second receiving portion20in the small bag, the hand bag and the pocket, like the first receiving portion1.

Preferably, the cloth member22is formed of antibiotic cotton paper. Furthermore, the cloth member22may be formed of other fabric material besides the antibiotic cotton paper.

The second receiving portion20is formed of the vinyl or aluminum foil24′. Preferably, the cloth member22is vacuously packed in the vinyl or the aluminum foil24′ in a state of being wet with a saline solution23.

The cloth member22can be withdrawn from the second receiving portion20after ripping a side of the second receiving portion20open using a detaching groove30′. The detaching groove30′ is formed at both opposite sides of the second receiving portion20. Therefore, in an emergency such as a fire, etc., the user can easily rip one side of the vinyl or aluminum foil24′ of the second receiving portion20and then withdraw the cloth member22.

As shown inFIGS. 4 and 5, the cloth member22is formed into a rectangular cotton handkerchief type, and may be a cotton grove type in which the user's fingers can be inserted, or a general mask type. In addition, it may be formed into a mouthpiece type in which the cloth member22that is wet with the saline solution is put in a plastic container, etc.

The reason why the cloth member22is kept in the second receiving portion20in the state of being wet with the saline solution23is to prevent an inflow of the poisonous gas when the user breathes in the emergency situation and thus to prevent a difficulty in breathing and also to prevent a deterioration of the cloth member22when the cloth member22is taken in custody for a long time.

However, the saline solution23can be substituted wit purified water or other solution which can effectively prevent the poisonous gas.

In addition, the cloth member22may have an active carbon portion (not shown) for filter the poisonous gas.

The cloth member22of the second receiving portion20is standardized into a small size, a middle size and a large size, so that the user can choose a proper size of the cloth member22according to a size of the user's face, i.e., a size of the user's nose and mouth.

FIGS. 1 to 7show a status that the face protector of the present invention is used.

If the poisonous gas is generated due to a fire, etc., the user rapidly rips the side of the vinyl or the aluminum foil24of the first receiving portion1open using the detaching groove30, and then withdraws the visibility securing member10from the first receiving portion1.

Then, the user rapidly peels off the protecting paper14from the attaching portion12using the separating portion15, and then air-tightly covers his/her face around eyes with the visibility securing member10using the adhesive surface13of the attaching portion12, as shown inFIG. 6.

Meanwhile, the cloth member22can be also withdrawn from the second receiving portion20after ripping the side of the vinyl or the aluminum foil24′ open using the detaching groove30′.

At this time, if the withdrawn cloth member22is the cotton handkerchief type, as shown inFIG. 7, the user takes hold of the cotton handkerchief and covers his/her own mouth and nose with the cotton handkerchief so as to prevent the poisonous gas from being come into his/her respiratory organ.

Although not shown in drawings, if the withdrawn cloth member22is the general mask, the user wears the mask on his/her ears using a string of the mask so as to protect the human being from the poisonous gas.

As described above, the face protector of the present invention is formed into a one-time product, so that the user can quickly escape from the critical region in a state that the face protector protects the user's eyes, noise and mouth, etc., from the poisonous gas generated in a fire. Particularly, when the fire breaks out in a subway, a kindergarten, a school, a dormitory, a tunnel, etc. the face protector according to the present invention can considerably reduce a loss of lives.

FIGS. 8 to 13experimental data and graphs showing a performance of the cloth member of the portable face protector according to the present invention.

FIG. 8is a test certificate from the Korea Institute of Construction Technology, andFIG. 9is a document describing an apparatus and method for testing the wet cloth member. The test conditions of the cloth member and the testing apparatus and method are described inFIG. 9. Therefore, the description thereof will be omitted.

FIGS. 10 and 11are an experimental data and a graph showing a change-over-time of a concentration of sulfur dioxide passing through the wet cloth member in a case that sulfur dioxide having a basic concentration of 197.2 ppm is passed through the wet cloth member under the test conditions ofFIG. 9.

First, as shown in the data and graph ofFIG. 10, the concentration of sulfur dioxide passing through the cloth member is ‘0’ for 312 seconds. However, after the time of 312 seconds, the concentration of sulfur dioxide is gradually increased.

InFIG. 11, the concentration of sulfur dioxide passing through the cloth member is ‘0’ for 235 seconds. However, after the time of 235 seconds, the concentration of sulfur dioxide is gradually increased.

As shown in the experimental result ofFIGS. 10 and 11, when the user covers his/her mouth and nose with the cloth member and escapes from the critical regions, the user can be protected from the poisonous gas such as the sulfur dioxide for at least 235˜312 seconds.

FIGS. 12 and 13are data showing a change-over-time of a concentration of hydrogen chloride passing through the wet cloth member in a case that hydrogen chloride having a basic concentration of 982 ppm is passed through the wet cloth member under the same test conditions as inFIG. 9.

As shown inFIG. 12, the concentration of hydrogen chloride passing through the cloth member is ‘0’ for 2015 seconds.

Also, in other three test results as shown inFIG. 13, the concentration of hydrogen chloride passing through the cloth member is ‘0’ for 307 seconds in data11, for 314 seconds in data12and for 314 seconds in data13, respectively.

As shown inFIGS. 12 and 13, the users can be safely protected from the poisonous gas such sulfur dioxide or hydrogen chloride while they escape from the critical region.

Since the face protector according to the present invention is small and light, anyone can conveniently carry the face protector in his/her pocket or handbag.

Further, since the face protector according to the present invention is low-priced, a large quantity of the face protectors can be provided at a public place such as a theater, a school, a subway, etc., at a low price. Thus, many human lives can effectively escape from the critical region in an emergency.
