Description

{Chair for combined use of safety cap}

The present invention relates to a chair combined with a helmet.

The phenomenon that the energy in the Earth comes out to the surface and the ground is shaken and shakes is called an earthquake. The principle of this earthquake is elastic rebound. Strata are warped and change their shape when they receive power. Then, when the forces that can not be sustained are accumulated, the stratum is broken and becomes a fault, and an earthquake occurs due to repulsive force to return to its original shape.

Most earthquakes are caused by large forces within the earth that affect the continent's movement, expansion of the sea floor, formation of mountains, etc. over a long period of time. In addition, earthquakes occur due to volcanic activity, but the scale is relatively small in this case. In addition, earthquakes may occur artificially by explosives.

Unlike the general weather phenomenon, the occurrence of earthquakes is virtually impossible to predict and predict. It is a very important disaster prevention factor as to how quickly you can wear safety gear from the time of the earthquake and guide you to a safe place. However, in the event of an earthquake, electricity is often blocked and the visibility can not be ensured. Even if the person who feels the earthquake is embarrassed, it is not easy to find the location of the helmet even though he knows the location of the helmet.

FIG. 1 is a perspective view showing a chair 100 as a chair according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the chair 100 as shown in FIG. 1, 1 is a perspective view showing a state in which a chair 100 for a safety helmet shown in FIG. 1 is mounted on a general standing chair 200. Hereinafter, a case will be described in which the chair 100 is used as a chair according to the present embodiment.

1 and 2, the chair 100 according to the present embodiment may include a backrest part 110 and a cushion part 120. As shown in FIG.

The backrest part 110 is a part for supporting the back of the user when the user is seated on the safety helmet 100. Here, the backrest 110 may include a first backrest region 111, a second backrest region 112, a bending region 113, and a first coupling region 114.

The first backrest region 111 is a portion directly touching the back of the user and the second backrest region 112 is a rear portion of the first backrest region 111 when the chair 100 is used as a chair, The first backrest region 111 can be positioned to face the first backrest region 111 to support the first backrest region 111. In addition, the bending region 113 may be bent to connect the first backrest region 111 and the second backrest region 112. Therefore, the first backrest region 111 and the second backrest region 112 can be facing each other with the bending region 113 being connected to each other as shown in Fig.

The first engagement region 114 is formed as a portion for connecting the backrest portion 110 and the cushioning portion 120 to each other and the second engagement region 121 and the first engagement region 114 of the cushioning portion 120, The second engagement region 121 may be detachably coupled through a Velcro, button, or the like. Meanwhile, in this embodiment, the first coupling region 114 may illustratively include a first sub coupling region 115 and a second sub coupling region 116. Here, the first sub-engagement region 115 may extend from the first backrest region 111 and the second sub-engagement region 116 may extend from the second backrest region 112. At this time, the second coupling region 121 of the cushion portion 120 is coupled to only one of the first sub-coupling region 115 and the second sub-coupling region 116 when used as a chair of the safety helmet 100 The second engagement region 121 is coupled only to the first sub-engagement region 115 and the second sub-engagement region 116 is folded to form the first and second backrest regions 111, 112). ≪ / RTI >

In addition, illustratively, the first sub-engagement region 115 and the second sub-engagement region 116 each include two first engagement members 118 located on both sides, and the second engagement region 121 includes both sides When the chair 100 is used as a chair in this embodiment, the two second joining members 125 (see FIG. 4) The member 125 may be coupled to each of the two first engagement members 118 of the first sub-engagement region 115. That is, the crotch part 120 can be stably coupled to the backrest part 110 by generating velcro, button coupling or the like at both ends.

The cushioning portion 120 may include a second engagement region 121 as a portion supporting the user's hips and may be coupled to the backrest portion 110 through a combination of the first engagement region 114 and the second engagement region 121. [ ). ≪ / RTI > In this case, it is not necessary to use the backrest 110 and the cushioning portion 120 in combination when using the chair as the chair for the safety helmet 100 according to the present embodiment. The backrest 110 and the cushion It is also possible to use the unit 120 separately.

Meanwhile, the safety helmet 100 according to the present embodiment may further include the elastic part 130 as an example. The elastic part 130 may be positioned at one side between the first and second backrest areas 111 and 112. The first backrest area 111 and the second backrest area 112, It is possible to apply elasticity so as to narrow the distance therebetween. Therefore, as long as there is no external force due to the elastic force of the elastic part 130, the first backrest area 111 and the second backrest area 112 can naturally face each other as shown in FIGS. However, the present invention is not limited to this, and the first backrest region 111 and the second backrest region 112 may be opposed to each other by their own elasticity or gravity without a separate elastic portion 130, It is possible to fix them by a clip member or the like.

As shown in FIG. 1, the chair 100 may be used as a sole chair, or may be covered with other common standing chairs 200 as shown in FIG. 3 to be a kind of cushion or a cushion member May be used. At this time, since the lower surface of the cushion portion 120 directly contacts the floor or the upper surface of the stocking chair 200, it may be preferable to implement it with a non-slip material.

Although not clearly shown, the inside of the cushion 120 according to the present embodiment may have a multi-layer structure of a cover 122, a soft material (not shown), and a hard material (not shown) toward the center. The cover 122 covers the outer surface of the cushion 120. The cover 122 may be made of a non-flammable material or a flame retardant material so as to be safe even in the event of a fire in the event of an earthquake or the like. . Further, the lining of the cover 122 may be made of a material capable of reducing thermal fatigue, so that it can be thermally deformed or not burned even in the event of a fire.

In addition, the soft material located inside the cover 122 may be made of a material that absorbs impact while having elasticity, such as a sponge used in a general cushioning material or the like. Therefore, it is possible to provide comfort when the user is seated in the safety helmet 100. Also, when the safety helmet is used as a safety helmet, it can absorb shocks caused by external fallen objects. In addition, a hard material may be placed inside the soft material. The hard material is a hard material compared to the soft material, and when the safety helmet 100 is used as a helmet, the hard material can prevent the cushion 120 from penetrating even if sharp dropping falls, thereby protecting the body faithfully. As such a member, a hard metal such as a metal plate may be used.

In this embodiment, the cushion part 120 is constructed of a cover 122, a soft material, and a hard material. However, the same multi-layer structure may be applied to the backrest part 110, It is also possible that such a multi-layer structure is applied to only a single layer.

Figs. 4A to 4C are perspective views sequentially illustrating the manner in which the chair 100 is deformed into a safety helmet shown in Fig. Hereinafter, a description will be given of a case where the safety helmet 100 according to the present embodiment is used as a helmet. The chair 100 is used as a chair as shown in FIG. 1, and can be transformed into a helmet as shown in FIG. 5 when an emergency such as an earthquake occurs. This modification will be described with reference to FIGS. 4A to 4C.

First, as shown in FIG. 4A, the coupling between the cushion 120 and the backrest 110 is separated. At this time, the second engagement region 121 of the cushion unit 120 is positioned in the first sub-engagement region 115 so that the cushion unit 120 faces the opposite side of the second backrest region 112 And can be positioned separately from the first sub-coupling region 115 (state as shown in FIG. 4A).

Next, as shown in FIG. 4B, the first backrest area 111 and the second backrest area 112 of the backrest 110 may be opened. At this time, the backrest 110 is folded over the first backrest region 111 and the second backrest region 111 through the bending region 113, as the folding region 111 is relatively stretched (i.e., the folding angle is increased) 4) between the first position (see FIG. 4A) in which the first backrest region 111 and the second backrest region 112 face each other (see FIG. 4A) and the second position Can be deformed while adjusting the angle between the backrest region (111) and the second backrest region (112). At this time, since the angle formed by the first backrest region 111 and the second backrest region 112 at the first position (FIG. 4A) is close to 0 °, the first backrest region 111 is formed at the second position (FIG. And the second backrest region 112, as shown in FIG. At this time, the elastic part 130 positioned between the first and second backrest areas 111 and 112 is stretched by an external force between the first backrest area 111 and the second backrest area 112 The first and second backrest regions 111 and 112 can be elastically urged to be adjacent to each other.

Meanwhile, the backrest part 110 according to the present embodiment may further include the connection area 117 as an example. Here, the connecting area 117 may be configured to connect the first backrest area 111 and the other side of the second backrest area 112 (i.e., the opposite side of the elastic part 130) 4a) and in a second position (Fig. 4b), the first backrest region 111 and the second backrest region 112 can be opened and spread apart. Here, the folded state and the unfolded state refer to relative differences, but they may not mean absolute folded states and unfolded states.

4C, the cushion portion 120 can be coupled to the backrest portion 110 in a state in which the first backrest region 111 and the second backrest region 112 are open. At this time, the second engagement region 121 of the cushion 120 can be coupled to both the first sub-engagement region 115 and the second sub-engagement region 116 of the backrest portion 110, and the cushion portion 120 The cushion part 120 can be coupled to the backrest part 110 so as to extend from one end to the first backrest area 111 and the second backrest area 112 while being substantially vertical. That is, the cushion part 120 may be coupled to the backrest part 110 so as to extend from one end of the backrest part 110 toward the opposite side of the bending area 113 of the backrest part 110.

Here, the coupling between the second engagement region 121 of the cushion unit 120 and the first engagement region 114 of the backrest unit 110 will be exemplified as follows. When the chair 100 is used as a chair as shown in FIG. 1, both side second engaging members 125 of the second engaging region 121 are engaged with both side first engaging members 118 of the first sub-engaging region 115, All of which can be combined. 4C, when the safety helmet 100 is used as a safety helmet, both side second engaging members 125 of the second engaging region 121 are engaged with the first sub-engaging region 115 and the second sub- 116 may be coupled to any one of the first coupling members 118 located on both sides of the first coupling member 118. [ That is, the second coupling member 125 on one side of the second coupling region 121 is engaged with the adjacent one of the first coupling members 118 on both sides of the first coupling member 118 on the first sub- And the other second coupling member 125 of the second coupling region 121 is coupled to only one of the adjacent first coupling members 118 of the both side first coupling members 118 of the second sub coupling region 116 . The first coupling member 118 of the first sub coupling region 115 and the first coupling member 118 of the other one of the second sub coupling region 116 of the first sub coupling region 115 may be disconnected from each other .

In addition, the first sub-engagement region 115 may be made of, for example, a flexible material and can be freely bent (adjusting the angle with respect to the first backrest region 111) from the first backrest region 111, The engagement area 116 may also be free to bend (adjust the angle with respect to the second backrest area 112) from the second backrest area 112. 4C, the angle formed by the first backrest region 111 and the first sub-engagement region 115 is greater than the angle formed by the first backrest region 111 and the first sub-engagement region 115 in FIGS. 1 and 4A, . 4C, the first sub-engagement region 115 and the second sub-engagement region 116 are positioned substantially parallel to the ends of the first backrest region 111 and the second backrest region 112, respectively, The second coupling region 121 on both sides of the cushion portion 120 may be coupled to both the first sub-coupling region 115 and the second sub-coupling region 116 by bending the cushion portion 120. At this time, the cushion part 120 must be inevitably rotated because the relative positions of the first coupling area 114 and the second coupling area 121 cause both sides of the cushion part 120 to be almost perpendicularly bent 2 coupling region 121 can engage with the first coupling region 114. In this case, When the cushion part 120 is bent, the cushion part 120 applies an elastic force to the backrest part 110 so that the first backrest area 111 and the second backrest area of the backrest 110 112 can be maintained. In addition, the cushion portion 120 should be bent to be overlapped on at least a part of the first sub-engagement region 115 and the second sub-engagement region 116 so that the length of the cushion portion 120 is the same as the length of the first May be longer than the distance between sub-coupling region 115 and second sub-coupling region 116. At this time, the shape of the cushion portion 120 may be seen as being coupled to the backrest portion 110 in such a manner that the first sub-engagement region 115 and the second sub-engagement region 116 partially overlap one another and are connected to each other. have.

FIG. 5 is a perspective view of the chair as a safety helmet of the safety helmet 100 shown in FIG. 4C. FIG. 6 is an example of a safety helmet of the safety helmet 100 shown in FIG. It is a perspective view. Hereinafter, an example of wearing the safety helmet 100 as a helmet of the safety helmet 100 will be described with reference to the following.

5 and 6, when the user wears the backrest 110, the backrest 110 protects the head of the user, and the cushioning portion 120 covers the back of the user's head. The user's back can be protected. Therefore, when a natural disaster such as an earthquake occurs, one of the most important parts of the human body can be protected from falling objects. In addition, since the cushion portion 120 or the backrest portion 110 includes the hard material 124 therein, it is possible for the safety helmet 100 to be prevented from being pierced by the sharp falling objects. Particularly, since the chair 100 is generally used as a chair, it can be easily found by a user even if a disaster occurs, and it is relatively easy to transform from a chair to a helmet, The body can be effectively protected.

When the user wears the safety helmet 100, the elastic part 130 narrows the space between the first backrest area 111 and the second backrest area 112 so that the safety helmet 100 is not separated from the user It is possible to perform the same function as a kind of neck line. In addition, the connection area 117 can protect the back of the user in the unfolded state. At this time, it is also possible to place one or more pores of a metal material in the connection area 117, for example, so that the feeling of fit of the user is not lowered by the connection area 117. A small lantern may be placed on the cover 122 of the cushion unit 120 or the backrest unit 110 to be used as a light source in the event of a disaster.

Although not shown clearly, the safety helmet 100 according to the present embodiment includes a back portion 110 and a cushion portion 120, and includes a fitting portion (not shown) extending from both ends of the back portion 110 . The fitting portion may be provided in the first backrest region 111 or the first sub-engagement region 115 and the second backrest region 112 or the second sub-engagement region 116, When the combined chair 100b is used as a helmet, the arm can be inserted into the hole of the fitting portion and can be positioned on the side of the arm. Thus, even if the user moves his or her body during a disaster, the chair 100b can be prevented from being separated from the user It is convenient to use both arms freely.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. Therefore, it should be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
