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

Referring to FIG. 1 , the portable safety helmet capable of air filling according to the embodiment may include a tube-shaped body 100 and a chin strap 200 connected to the body 100 . The body 100 is made of a flexible material and expands when air is injected therein to maintain 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 serve as a buffer against external forces, and can give a feeling of closeness to the wearer's head. When air escapes from the inside of the body 100 , the body 100 contracts. The contracted body 100 has the advantage of being easily portable because the volume is greatly reduced and it can be folded. In addition, since the body 100 is very light, there is an advantage of being more easily portable.

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

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

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

2 is a plan view of the portable safety helmet that can be filled with air shown in FIG. 1, and is a view showing the flow of air injected therein, and FIG. 3 is an enlarged view of area A of FIG. 1 and shows the reinforcement plate 300. It is one view, and FIG. 4 is a side cross-sectional view of the connection part 130 of the portable safety helmet that can be filled with air shown in FIG. 1 .

2 to 4 , the body 100 may include a first air flow path 101 therein, and a first air inlet 103 communicating with the first air flow path 101 . The first air flow path 101 may be formed throughout the body 100 . The first air inlet 103 may be disposed on the rear portion 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 surface 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 may be easily damaged by a strong external impact. In particular, the body 100 may be torn by a sharp object. A portable safety helmet capable of air filling according to the embodiment is provided with a plurality of small reinforcing plates 300 in order to prevent this. The plurality of reinforcing plates 300 may be entirely attached to the outer surface of the body 100 exposed when worn. The reinforcing plate 300 may be fixed to the outer surface of the body 100 through an adhesive.

In addition, the plurality of reinforcing plates 300 may be disposed with a predetermined gap G from each other. The size W2 of the gap G between the reinforcing plate 300 and the reinforcing plate 300 may be less than or equal to 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, the reinforcing plate 300 does not interfere when the body 100 is folded in a state in which air is removed from the body 100. Without it, the body 100 can be easily folded. This 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 being able to easily fold the body 100 while maximally widening the protective area of the body 100 by minimizing the gap (G). Although the reinforcing plate 300 is illustrated as a flat plate-shaped member, the reinforcing plate 300 including a curved surface may be disposed on the curved portion of the body 100 .

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

As shown in FIG. 4 , an endothelium 106 may be attached to the inner surface of the body 100 . The endothelium 106 is a portion in direct contact with the wearer's head, and may be made of an elastically deformable material.

5 is a view from the rear of the portable safety helmet that can be filled with air shown in FIG. 1, and FIG. 6 is a view showing a state in which the protrusion 122 of the portable safety helmet that can be filled with air shown in FIG. 5 is expanded.

4 to 5 , the body 100 may be sized 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 has a concave portion 121 , an elastic band 500 disposed over the concave portion 121 , and a protrusion disposed in the concave portion 121 . (122).

The concave portion 121 is formed to be concave upwardly 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 in the center of the body 100 . A second air flow path 102 may be formed inside the protrusion 122 . The second air flow path 102 is an internal space of the body 100 that is partitioned from the first air flow path 101 . And the protrusion 122 includes a second air inlet 104 communicating with the second air flow passage (102). The elastic band 500 penetrates the protrusion 122 from 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).

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

When the 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 helmet, the elastic band 500 may be expanded in response to the size of the wearer's head. When the elastic band 500 is expanded, the body 100 tightens the wearer's head due to the restoring force of the elastic band 500, thereby increasing a feeling of closeness between the body 100 and the wearer's head.

Even when the wearer's head, in particular, the temporal part of the wearer's head is much larger than the size of the body 100, since the elastic band 500 is expanded, 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 is expanded. As the protrusion 122 is expanded, only the elastic band 500A located inside the second air flow path 102 is expanded without affecting the elastic band 500 disposed on the outside of the protrusion 122 . As such, when the protrusion 122 expands, since the size of the rear part 120 increases, the overall size of the body 100 may be expanded.

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

The body 100 may include a first pleated portion 107 and a second pleated portion 108 .

A first elastically deformable first tightening member 600 is disposed on the first wrinkle portion 107 . A second 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 pleats 108 are disposed above the first pleats 107 , and may be inclined with respect to the first pleats 107 .

Since the body 100 is light, the body 100 may be peeled off from the user's head by the wind during wearing. It is possible to prevent the helmet from coming off by increasing the adhesion and stability of the wearer's head and adjusting it.

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

6 and 7 , the body 100 may include a light emitting unit 400 therein. Due to the light irradiated from the light emitting unit 400, the wearer's visibility at night may be improved.

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

Meanwhile, the light guide film 105 may be attached to the inner surface of the body 100 forming the first air flow path 101 . The entire 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 .

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

Although the light emitting unit 400 is disposed on the rear side as described above, since 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, the night visibility of the hard hat can be greatly improved. .

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

In addition, as shown in FIG. 7 , the light emitting part 400 may be disposed to be aligned with the protrusion 122 and disposed in 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 the respective light irradiation directions are different from each other. This is generally to diversify the irradiation direction of the light so that the light is extended to the entire area of the body 100 .

As such, when the irradiation directions of the plurality of LED modules 410 are different, brightness can be uniformly secured as a whole body 100 .
