The present invention relates to a portable safety helmet that can be filled with air, and is made of a flexible material, and relates to a portable safety helmet that can be filled with air and whose volume can be changed by injecting or withdrawing air.

In order to enjoy leisure sports such as skiing, bicycle, rafting, bicycle, inline skating, electric wheel, electric kickboard, motorcycle, etc., a safety helmet must be worn to prevent safety accidents.

The safety helmet includes a body having a hemispherical shape corresponding to the shape of the wearer's head and a chin strap coupled to the body. The body may be made of a soft shock absorbing member. This body protects the wearer's head from external impact.

Since the body has to be formed to cover not only the back of the head but also the side of the head of the wearer, it must have a certain volume. Because of this, there is a problem that the hard hat is difficult to carry after being detached. In addition, in the case of the body, when an external impact is repeated, the body is damaged, and there is a problem in that the buffering power of the body is lowered.

Therefore. Republic of Korea Patent Application No. 2001-0042000 (2001.07.12) discloses a tube-shaped safety helmet into which air is injected. However, these safety helmets can increase portability by reducing the volume by removing air, but have a problem in that they are very vulnerable to external impact because the outer shell is soft. In particular, the risk of tearing the hard hat by sharp objects is very high.

1 is a view showing a portable safety helmet that can be filled with air according to an embodiment.

Referring to FIG. 1 , a portable safety helmet capable of being filled with air according to an embodiment may include a tubular body 100 and a chin strap 200 connected to the body 100 . The body 100 is made of a flexible material, expands when air is injected therein, and maintains a hemispherical shape so that the user can wear it on the head. The body 100 may be made of any one of synthetic rubber, polyether, and reinforced polyvinyl.

Since the inside of the body 100 is filled with air, it can act as a buffer against external force and can give a sense of closeness to the wearer's head. When air is released from the inside of the body 100, the body 100 contracts. Since the contracted body 100 is greatly reduced in volume and can be folded, it has the advantage of being easy to carry. In addition, since the body 100 is very light, it has the advantage of being more portable.

The body 100 may include a front part 110 and a rear part 120 and a plurality of connection parts 130 . The front portion 110 is a portion that covers the front of the wearer when worn. The rear part 120 is a part that covers the wearer's larynx when worn. And the plurality of connection parts 130 connects the front part 110 and the rear part 120 . The connecting portion 130 is a portion that covers the temporal and parietal regions of the wearer's head when worn.

The plurality of connecting parts 130 may be spaced apart from each other to secure a ventilation area in which a part of the wearer's head is exposed to the outside.

The chin strap 200 may be detachably coupled to the body 100 .

FIG. 2 is a plan view of the air-filled portable safety helmet shown in FIG. 1, showing the flow of air injected therein, and FIG. 3 is an enlarged view of area A in FIG. 1 and shows a reinforcing plate 300. This is a drawing, and FIG. 4 is a side cross-sectional view of the connection part 130 of the portable safety helmet capable of filling air shown in FIG.

Referring to FIGS. 2 to 4 , the body 100 may include a first air passage 101 therein and a first air inlet 103 communicating with the first air passage 101 . The first air passage 101 may be formed over the entire body 100 . The first air inlet 103 may be disposed on the rear part 120, but the present invention is not limited thereto. When air is injected into the first air inlet 103 , the injected air is supplied to the plurality of connection parts 130 across the rear part 120 . The air supplied to the connection part 130 is supplied to the front part 110 .

Since the body 100 is made of a flexible material, it can be easily damaged by a strong external impact. In particular, the body 100 may be torn by a sharp object. The portable safety helmet capable of filling air according to the embodiment includes a plurality of small reinforcing plates 300 to prevent this. The plurality of reinforcing plates 300 may be entirely attached to the outer surface of the body 100 that is exposed when worn. The reinforcing plate 300 may be fixed to the outer surface of the body 100 through an adhesive.

And a plurality of reinforcing plates 300 may be disposed with a constant gap (G) from each other. The size W2 of the gap G between the reinforcing plates 300 and the reinforcing plates 300 may be less than 1/10 of the width W1 of the reinforcing plate 300 . Since there is such a gap (G) between the reinforcing plate 300 and the reinforcing plate 300, when the body 100 is folded in a state in which air is removed from the body 100, the reinforcing plate 300 does not interfere. Without, the body 100 can be easily folded. The reinforcing plate 300 protects the outer surface of the body 100 from physical impact. The reinforcing plate 300 may be made of a material having sufficient hardness to safely withstand external impact.

The reinforcing plate 300 may be a square plate-shaped member. The square reinforcing plate 300 has the advantage of easily folding the body 100 while maximally widening the protection area of the body 100 by minimizing the gap G. Although the reinforcing plate 300 is exemplified as a flat plate-like member, the reinforcing plate 300 including a curved surface may be disposed on a curved portion of the body 100 .

Among the plurality of reinforcement plates 300, the thickness of the reinforcement plate 300 of the connection portion 130 vulnerable to external impact may be made thicker than the thickness of the reinforcement plate 300 disposed on the front part 110 or the rear part 120. there is.

As shown in Figure 4, the endothelium 106 may be attached to the inner surface of the body 100. Endothelial 106 is a portion that directly contacts the wearer's head and may be made of an elastically deformable material.

5 is a view of the portable safety helmet capable of filling air shown in FIG. 1 viewed from the rear, and FIG. 6 is a view showing a state in which the protrusion 122 of the portable safety helmet capable of filling air shown in FIG. 5 is expanded.

Referring to FIGS. 4 and 5 , the size of the body 100 may be adjusted to correspond to the size of the wearer's head. As a configuration for adjusting the size of the body 100, the rear portion 120 includes a concave portion 121, an elastic band 500 disposed across the concave portion 121, and a protrusion disposed on the concave portion 121. (122).

The concave portion 121 is formed concave upward from the lower end of the rear portion 120 . The protrusion 122 protrudes downward from the concave portion 121 . The protrusion 122 may be located at the center of the body 100 . A second air passage 102 may be formed inside the protrusion 122 . The second air passage 102 is an inner space of the body 100 partitioned from the first air passage 101 . And the protrusion 122 includes a second air inlet 104 communicating with the second air passage 102 . The elastic band 500 passes through the protrusion 122 at one side of the concave portion 121 and is connected to the other side of the concave portion 121 . At this time, the elastic band 500 is disposed through the second air passage 102 .

Therefore, a portion of the elastic band 500 is disposed between one side of the concave portion 121 and the protruding portion 122, and a portion of the elastic band 500 is disposed between the other side of the concave portion 121 and the protruding portion 122. do. Then, the remaining part of the elastic band 500 is disposed inside the protruding portion 122. The elastic band 500 is a member having restoring force when expanded.

When the safety helmet is not worn, the protrusion 122 and the second air passage 102 maintain a contracted state due to the restoring force of the elastic band 500 . At this time, the protrusion 122 is contracted in a wrinkled state due to the elastic band 500 . When the wearer wears the hard hat, the elastic band 500 may be expanded in response to the size of the wearer's head. When the elastic band 500 is extended, the body 100 tightens the wearer's head due to the restoring force of the elastic band 500, so that a sense of closeness between the body 100 and the wearer's head can be increased.

Even if the wearer's head, in particular, the side of the wearer's head is much larger than the size of the body 100, since the elastic band 500 expands, wearing is possible, but the elastic band 500 tightens the wearer's head. Therefore, it may cause pain to the wearer.

At this time, as shown in FIG. 6 , when air is injected into the second air passage 102 through the second air inlet 104 , the protrusion 122 expands. As the protrusion 122 expands, it does not affect the elastic band 500 disposed outside the protrusion 122 and expands only the elastic band 500A located inside the second air passage 102 . In this way, when the protrusion 122 expands, since the size of the rear portion 120 increases, the overall size of the body 100 can be expanded.

In this way, the size of the body 100 is increased in response to the wearer's head, but the restoring force of the elastic band 500 located inside the protrusion 122 is supported by pneumatic pressure inside the second air passage 102. Therefore, as the elastic band 500 is stretched, the force to tighten the wearer's head is greatly reduced, and the wearer can prevent the wearer from feeling pain.

The body 100 may include a first wrinkle part 107 and a second wrinkle part 108 .

An elastically deformable first tightening member 600 is disposed on the first wrinkle portion 107 . An elastically deformable second tightening member 700 is disposed on the second wrinkle portion 108 . The first tightening member 600 and the second tightening member 700 may each have a stretchable string shape. The second wrinkle part 108 is disposed above the first wrinkle part 107 and may be inclined with respect to the first wrinkle part 107 .

Since the body 100 is light, the body 100 can be removed from the user's head by wind during wearing, and the first tightening member 600 and the second tightening member 700 are It is possible to prevent the hard hat from coming off by increasing and adjusting the adhesion and seating properties of the wearer's head.

FIG. 7 is a view showing the light emitting unit 400 disposed inside the body 100 .

The body 100 and the reinforcing plate 300 are each made of a transparent material so that light irradiated from the LED module 410 can be transmitted to the outside of the body 100.

Meanwhile, a light guide film 105 may be attached to an inner surface of the body 100 forming the first air passage 101 . The light guide film 105 is attached to the inner surface of the front part 110, the inner surface of the rear part 120, and the inner surface of the connection part 130 as a whole.

A part of the light irradiated from the LED module 410 may be reflected from the light guide film 105 and proceed. The light emitting part 400 may be disposed inside the rear part 120 of the body 100. Light irradiated from the rear part 120 side is reflected by the light guide film 105, and the connecting part 130 and the front part 110 ), the light can be transmitted to the entire area of the body 100.

As such, although the light emitting unit 400 is disposed on the rear side, the night visibility of the safety helmet can be greatly improved because the light irradiated to the light emitting unit 400 is transmitted to the entire area of the body 100 through the light guide film 105. .

A switch for turning on/off the light emitting unit 400 may be disposed on a side surface of the body 100 . The switch is electrically connected to the controller 430.

In addition, as shown in FIG. 7 , the light emitting part 400 may be arranged to be aligned with the protruding part 122 and disposed at the center of the body 100 . A plurality of LED modules 410 may be disposed. In addition, the plurality of LED modules 410 may be arranged so that each light irradiation direction is different from each other. This is to diversify the irradiation direction of light so that the light generally extends to the entire area of the body 100 .

As such, if the irradiation directions of the plurality of LED modules 410 are different, the body 100 can ensure uniform brightness throughout.

Referring to FIG. 8 , a portable safety helmet capable of being filled with air according to another embodiment may inject air into the body 100 through an air pump 800 .
