Description

The present invention relates to a disaster prevention hood that protects the head by wearing it in the event of a disaster such as an earthquake.

Conventionally, disaster prevention hoods that simply protect the head in the event of a disaster have become widespread. This disaster prevention hood is generally constructed by folding two rectangular cloth bags (such as a quilt) filled with batting in half and sewing the overlapping long sides on one side together, which is inferior in head protection to a helmet. However, it has the advantages of being lightweight and excellent in storage and portability.

Further, in recent years, a paper hat or the like that simply protects the head has been proposed. (See, for example, Patent Document 1). When a hat for head protection is constructed from members such as cardboard and corrugated cardboard, which have higher shape retention than cloth, the head protection is better than that of cloth disaster prevention hoods by utilizing the shock absorption when the members are deformed. Can be enhanced. In addition, when not in use, the storability can be improved by making the structure foldable into a flat plate.

Japanese Unexamined Patent Publication No. 2013-256728

However, in the hat described in Patent Document 1, although the shock absorption is enhanced by providing a space between the top edge of the hat and the head, a relatively thick cushioning material is attached to the inner surface. Since it is attached, it cannot be folded thinly, and there is a problem that the storage capacity is low.

In view of such a situation, the present invention intends to provide a disaster prevention hood that has both head protection and storability.

The disaster prevention hood of the present invention is composed of an outer member composed of a flat plate folded by the first fold line and a flat plate folded by the second fold line, and the second fold line is the same as the first fold line. It is sandwiched inside the outer member with a gap between the portion of the second fold line of itself and the portion of the outer member of the first fold line on the side, and is sandwiched on both sides of the second fold line. It is characterized by including an inner member in which a portion separated from the second fold line is fixed to the outer member, respectively.

According to the disaster prevention hood of the present invention, an appropriate gap can be created between the outer member and the inner member simply by opening the outer member and the inner member from the folded state by the first fold line and the second fold line. Therefore, by bringing the inner member into contact with the wearer's head when wearing the disaster prevention hood, the outer member is deformed between the head and the outer member regardless of the shape and size of the head. It is possible to secure a space that can absorb the impact, and it is possible to improve the head protection without significantly impairing the storability. That is, it is possible to achieve both head protection and storage of the disaster prevention hood.

Further, in the present invention, the outer member has two outer upper wall portions connected to each other via the first fold line, and the first fold in the outer upper wall portion via the first sub fold line. It has two outer side walls that are connected to each other on the edge opposite to the line of sight, and the inner members are two inner upper wall parts that are connected to each other via the second fold line, and a second. The inner side wall portion has two inner side wall portions that are connected to each other at the edge of the inner upper wall portion on the opposite side of the second fold line via the second fold line, and the inner side wall portion is the second sub fold line. A state in which the fold line substantially coincides with the first sub-fold line, or a state in which the second sub-fold line is arranged on the edge side of the first sub-fold line opposite to the first sub-fold line. It is preferably fixed to the outer side wall portion.

According to this, by appropriately setting the relative positions of the first sub-fold line and the second sub-fold line, the gap between the outer member and the inner member can be adjusted to an appropriate size, and the outer side wall portion and the outer side wall portion and Since the inner side wall portion can cover and protect the wearer's head from the side, the head protection can be further enhanced.

Further, in the present invention, at least one of the outer member and the inner member is formed on two outer side walls or two inner side walls via a first vertical fold line in a direction intersecting the first fold line. It is preferable that each of the two rear wall portions is connected to each other, and the rear wall portions are connected to each other via a second vertical fold line in a direction intersecting the first fold line.

According to this, the rear wall portion limits the deformation of the outer member and the inner member so as to open, and it is possible to cover and protect the wearer's head from the rear, thus providing head protection. Can be enhanced.

Further, in the present invention, in the rear wall portion, the edge on the second vertical fold line side is closer to the first fold line side or the second fold line side than the edge on the first vertical fold line side. It is preferable that the shape extends toward.

According to this, the rear wall portion covers the entire head of the wearer from the rear, and the outer upper wall portion deformed at the time of collision of a falling object or the like collides with the upper end edge of the rear wall portion to deform it. This makes it possible to exert a shock absorbing effect, so that the head protection can be further enhanced.

Further, in the present invention, the inner upper wall portion has an intermediate fold line provided so as to connect the edge other than the edge on the second fold line side and the edge on the second sub fold line side. Is preferable.

According to this, since it is possible to improve the fit of the inner member to the head, it is possible to improve the stability of the disaster prevention hood in the event of a collision of a falling object or the like, and to improve the comfort of wearing the disaster prevention hood. ..

Further, the disaster prevention hood of the present invention has a string-like or band-like shape that connects the outer side wall portion or the inner side wall portion on one side with the outer side wall portion or the inner side wall portion on the other side with respect to the first fold line. It is preferable to include a connecting member.

According to this, by arranging the connecting member at an appropriate position, it is possible to limit the deformation of the outer member and the inner member so as to open like the rear wall portion, and further, when a falling object or the like collides. Since it is possible to effectively prevent the disaster prevention hood from shifting from the wearer's head, it is possible to further enhance the head protection.

Further, in the present invention, it is preferable that the outer member is made of corrugated cardboard, and the first fold line is provided so as to intersect the direction of the corrugated cardboard in the outer member diagonally.

According to this, while the outer member is composed of lightweight and inexpensive corrugated cardboard, the shape retention of the outer member is improved by crossing the first fold line with the direction of the corrugated cardboard, and the head protection of the disaster prevention hood is improved. Can be enhanced. Furthermore, by preventing the first fold line from being perpendicular to the direction of the corrugated cardboard, the wavy pattern of the inner core should appear on both edges in the direction of the first fold line, which is noticeable when wearing a disaster prevention hood. Therefore, it is possible to improve the appearance of the disaster prevention hood while improving the head protection.

Further, in the present invention, it is preferable that the inner member is made of corrugated cardboard and the second fold line is provided parallel to the direction of the corrugated cardboard in the inner member.

According to this, while the inner member is made of lightweight and inexpensive corrugated cardboard, by making the second fold line parallel to the direction of the corrugated cardboard, both sides in the direction of the second fold line are noticeable when wearing the disaster prevention hood. Since it is possible to make the wavy pattern of the inner core appear on the edge of the corrugated cardboard, the appearance of the disaster prevention hood can be improved. Further, by connecting the rear wall portion to the inner member, the first vertical crease line and the second vertical crease line can be crossed with the direction of the corrugated cardboard, so that the shape retention of the rear wall portion is improved. , Head protection can be enhanced.

According to the disaster prevention hood according to the present invention, it is possible to achieve an excellent effect that both head protection and storage are possible.

The second fold line 20a, which is in the front-rear direction (vertical direction in the figure) after the disaster prevention hood 1 is assembled, is configured to be substantially line-symmetrical except for the adhesive piece 24.

Specifically, the two inner upper wall portions 21 are connected to each other via the second fold line 20a. Further, the two inner side wall portions 22 are connected to the edge of the inner upper wall portion 21 on the opposite side of the second fold line 20a via the second sub fold line 20b.

The two rear wall portions 23 are connected to the rear edge of the two inner side wall portions 22 after assembly via the first vertical crease line 20c. The adhesive piece 24 is connected to the edge of one of the two rear wall portions 23 (on the left side in the figure) on the rear side (upper side in the figure) after assembly via the second vertical crease line 20d. There is.

The second fold line 20a is provided substantially parallel to the direction of the corrugated cardboard of the inner member 20 (vertical direction in the figure). Further, the second sub-fold line 20b is provided substantially parallel to the second fold line 20a. Further, the first vertical fold line 20c and the second vertical fold line 20d are provided so as to be substantially orthogonal to the second vertical fold line 20a.

The second fold line 20a, the second sub fold line 20b, the first vertical fold line 20c, and the second vertical fold line 20d are each composed of ruled lines. Further, the second fold line 20a and the second sub fold line 20b are further provided with perforations formed of intermittent linear cuts, and are configured to be easily bent.

An intermediate fold line 20e substantially parallel to the second fold line 20a is provided at a predetermined position on the side of the second fold line 20a of the inner upper wall portion 21. The intermediate fold line 20e is composed of a ruled line provided with perforations, similarly to the second fold line 20a and the second sub fold line 20b.

The inner side wall portion 22 is provided with a circular through hole 25 at a predetermined position on the front side after assembly and on the side of the first sub-fold line 10b. The through hole 25 has an inner diameter slightly larger than that of the through hole 13 of the outer member 10, and communicates with the through hole 13 in a state where the axis is substantially aligned with the through hole 13 after assembly.

The rear wall portion 23 has a trapezoidal shape in which the rear end edge 23a after assembly extends toward the second fold line 20a side from the front edge after assembly. The rear side of the rear wall portion 23 after assembly and the acute-angled corner portion on the second fold line 20a side are provided with appropriate roundness.

The adhesive piece 24 is bonded to the rear wall portion 23 of the other side (on the right side in the figure) to connect the rear wall portions 23 to each other via the second vertical crease line 20d, and is connected to the tip side (FIG. The edge of (upper side) is formed in a trapezoidal shape shorter than the edge of the base end on the second vertical crease line 20d side (lower side in the figure). Further, the edge of the adhesive piece 24 on the second vertical fold line 20d side is shorter than the edge of the rear wall portion 23 which is continuously provided, and the adhesive piece 24 is folded second with respect to the rear wall portion 23. It is offset and connected to the opposite side of the line of sight 20a (on the right side of the figure). That is, the adhesive piece 24 is configured so as not to protrude from the vicinity of the acute-angled corner portion of the rear wall portion 23 on the mating side after adhesion.

The dimension (distance) a1 between the first fold line 10a and the first sub-fold line 10b on the outer upper wall portion 11 of the outer member 10 is the second fold line 20a and the second on the inner upper wall portion 21 of the inner member 20. It is set to be larger than the dimension (distance) a2 between the sub fold lines 20b. Further, the dimension (distance) b1 between the first sub-fold line 10b on the outer side wall portion 12 of the outer member 10 and the end edge 12a on the opposite side thereof is the second sub-crease line 20b on the inner side wall portion 22 of the inner member 20. It is set to be larger than the dimension (distance) b2 between and the edge 22a on the opposite side.

Further, the dimension (distance) c1 between the first vertical fold line 20c in the rear wall portion 23 of the inner member 20 and the rear edge 23a (or the second vertical crease line 20d) after assembly is the inner side wall portion 22. It is set smaller than the dimension (distance) b2 between the second sub-fold line 20b and the end edge 22a on the opposite side thereof.

2A and 2B are schematic perspective views showing a method of assembling the disaster prevention hood 1. In assembling the disaster prevention hood 1, as shown in FIG. 2A, the inner member 20 is first folded back along the second fold line 20a and folded in half. Then, the adhesive piece 24 is folded back along the second vertical fold line 20d and adhered to the overlapping rear wall portions 23 so that the two rear wall portions 23 are connected to each other.

Next, the outer member 10 is folded back along the first fold line 10a and folded in half. Then, the inner member 20 is sandwiched inside the outer member 10 with the second fold line 20a of the inner member 20 facing the same side as the first fold line 10a of the outer member 10, and the edge 12a and the edge 22a are omitted. In the matched state, the inner side wall portion 22 is adhered and fixed to the overlapping outer side wall portions 12.

As described above, since the dimensions a1 and b1 of the outer member 10 are larger than the dimensions a2 and b2 of the inner member 20, the inner side wall portion 22 is provided to the outer side wall portion 12 by substantially matching the end edge 12a and the end edge 22a. By fixing, as shown in FIG. 2B, the distance d1 (≈a1 + b1-a2-b2) is between the portion of the outer member 10 at the first fold line 10a and the portion of the inner member 20 at the second fold line 20a. ) Will be created.

Further, the second sub-fold line 20b of the inner member 20 is arranged at a position separated from the first sub-fold line 10b of the outer member 10 by a distance d2 (= b1-b2) toward the end edge 12a. Become. Therefore, the inner side wall portion 22 overlaps only the outer side wall portion 12 and does not overlap with the outer upper wall portion 11.

Finally, the string-shaped or strip-shaped connecting member 30 is appropriately fixed to either the left or right side of the through holes 13 and 25 (in the present embodiment, the front side in the drawing) that communicate with each other. The connecting member 30 is for preventing the disaster prevention hood 1 from falling off from the head by connecting the left and right outer side wall portions 12 and the inner side wall portion 22 in the same manner as a general chin strap. It also functions as a reinforcing member that enhances the protection of the disaster prevention chin width 1.

The disaster prevention hood 1 is completed by the above procedure. The method of assembling the disaster prevention hood 1 is not limited to the above procedure, and the order of each step may be changed as appropriate. For example, after adhering one inner side wall portion 22 and the outer side wall portion 12, the outer member 10 may be folded back, and the other inner side wall portion 22 and the outer side wall portion 12 may be adhered. Further, after bonding both the left and right inner side wall portions 22 and the outer side wall portion 12, the adhesive piece 24 may be folded back and adhered to the rear wall portion 23. Further, in the present embodiment, the front end edge of the outer side wall portion 12 and the front end edge of the inner side wall portion 22 are made to substantially match, but they may not match.

As shown in FIG. 2B, the completed disaster prevention hood 1 is in a relatively thinly folded state with a thickness (approximately 16 mm) equivalent to two sheets of corrugated cardboard of approximately A flute and two sheets of corrugated cardboard of B flute. It is in a state of excellent storability. In addition, since the outer shape is a substantially rectangular flat plate, efficient storage is possible, for example, by stacking in two rows in a cardboard box, and further, it can be stored in a small gap such as a bookshelf or a cabinet. Even if it does not get in the way.

3 and 4 are schematic perspective views showing a case where the disaster prevention hood 1 is in a wearable state. Note that FIG. 3 is a view seen from the front side, and FIG. 4 is a view seen from the rear side. From the state shown in FIG. 2B, by opening the outer member 10 and the inner member 20 to the left and right so as to separate the two inner side wall portions 22 from each other, the disaster prevention hood 1 can be easily and quickly put into a wearable state. ..

As shown in FIG. 3, in a wearable state, the two outer upper wall portions 11 have a gable roof shape with the portion of the first fold line 10a as the apex. Then, the two inner upper wall portions 21 are in a state of bulging in a polygonal shape toward the upper outer upper wall portion 11 side with an appropriate gap between them and the outer upper wall portion 11.

Further, as shown in FIG. 4, the two rear wall portions 23 have a gable roof shape that slightly protrudes rearward with the second vertical fold line 20d as the apex. Then, the portion extending rearward of the outer upper wall portion 11 covers the two rear wall portions 23 protruding rearward from the outer side wall portion 12 from above. Further, although not shown, the upper end edges of the two rear wall portions 23 have a V shape substantially parallel to the upper outer upper wall portion 11.

As shown in FIGS. 3 and 4, the connecting member 30 is left and right by passing the tip portion through the other through holes 13 and 25 and appropriately winding the connecting member 30 between the outer side wall portion 12 and the front end edge of the inner side wall portion 22. It is arranged so as to connect the outer side wall portion 12 and the inner side wall portion 22 of the above.

FIG. 5 is a schematic perspective view showing a wearing state of the disaster prevention hood 1. The disaster prevention head width 1 adjusts the distance between the inner side wall portions 22 to match the width of the wearer's head by adjusting the opening angles at the first fold line 10a, the second fold line 20a, and the second vertical fold line 20d. Is possible. Further, due to the bending at the second fold line 20a, the second sub fold line 20b, and the intermediate fold line 20e, the inner upper wall portion 21 is in stable contact with the wearer's crown in a state of being fitted. By contacting the inner upper wall portion 21 with the wearer's crown, an appropriate gap, that is, between the outer upper wall portion 11 and the wearer's crown, regardless of the shape and size of the wearer's head. The outer upper wall portion 11 is deformed to maintain the gap required to absorb the impact.

Since the opening angle at the first fold line 10a is the dimension a1 of the outer upper wall portion 11> the dimension a2 of the inner upper wall portion 21> the dimension c1 of the rear wall portion 23, the two rear wall portions connected to each other are connected to each other. 23 limits the angle to a predetermined angle (approximately 2 × arcsin (c1 / a1) degrees) or less on the rear side. Further, the connecting member 30 appropriately connects the left and right outer side wall portions 12 and the inner side wall portion 22, so that the opening angle at the first fold line 10a is an angle substantially corresponding to the width of the wearer's head on the front side. It will be limited to the following. That is, the outer upper wall portion 11 is reinforced by the rear wall portion 23 and the connecting member 30 so as to maintain the gable roof-like shape (shape retention is enhanced).

Therefore, in the disaster prevention hood 1, when a falling object or the like collides with the outer upper wall portion 11, the outer upper wall portion 11 is appropriately deformed (crushed) regardless of the shape and size of the wearer's head. It absorbs shocks and protects the wearer's head. Further, since the inner upper wall portion 21 is located between the outer upper wall portion 11 and the wearer's head, the deformed outer upper wall portion 11 does not directly collide with the wearer's head, and should it occur. Even if the outer upper wall portion 11 is torn, a falling object or the like does not directly collide with the wearer's head unless the inner member 20 is torn.

Further, in the disaster prevention hood 1, since the outer upper wall portion 11 extends rearward, the rear wall portion 23 is covered from above by the outer upper wall portion 11. As a result, the disaster prevention hood 1 can also exert a shock absorbing effect by deforming the rear wall portion 23 when the deformed outer upper wall portion 11 collides with the upper end edge of the rear wall portion 23.

Further, even when the width of the wearer's head is narrow and the amount of protrusion of the rear wall portion 23 to the rear is large due to the rearward extending portion of the outer upper wall portion 11, the wearer's head is still present. When viewed from above, it is shielded by the outer upper wall portion 11. Similarly, the wearer's head is shielded by the outer upper wall portion 11, the outer side wall portion 12 and the rear wall portion 23 when viewed from the side, and the inner side wall portion 22 when viewed from the rear. It is shielded by a rear wall portion 23 that extends upward. That is, the disaster prevention hood 1 is configured so that the wearer's head is not exposed when viewed from above, sideways, or rearward, and effectively protects the wearer's head. ing.

Further, as shown in FIG. 5, since the connecting member 30 is arranged at a position corresponding to the wearer's forehead in the wearing state, the disaster prevention chin width 1 shifts backward in the event of a collision of a falling object or the like. Is designed to be prevented more effectively than conventional chin straps.

As described above, the disaster prevention hood 1 can be thinly folded into a substantially rectangular flat plate shape when not worn, but has sufficient head protection as compared with the conventional disaster prevention hood and the like. That is, the disaster prevention hood 1 has both storability and head protection.

In the present embodiment, the outer upper wall portion is formed by setting the direction of the corrugated cardboard of the outer member 10 so as to intersect the first fold line 10a and the first sub crease line 10b at an angle of about 70 degrees. While improving the shape retention of 11, the wavy pattern of the inner core appears on the front end edge and the rear end edge of the outer member 10 after assembly.

Further, the direction of the corrugated cardboard of the inner member 20 is substantially parallel to the second fold line 20a, the second sub fold line 20b and the intermediate fold line 20e, and is substantially orthogonal to the first vertical fold line 20c and the second vertical fold line 20d. By setting the direction, the shape retention of the rear wall portion 23 is improved, and the wavy pattern of the inner core appears on the front end edge and the rear end edge of the inner member 20 after assembly. Further, by intersecting the corrugated cardboards of the outer side wall portion 12 and the inner side wall portion 22, the strength of the side wall portion in which these are overlapped is also improved.

That is, in the present embodiment, not only the head protection of the disaster prevention hood 1 is improved, but also the wavy pattern of the inner core appears at the front end edge and the rear end edge of the outer member 10 and the inner member 20 which are noticeable when worn. By doing so, the appearance of the disaster prevention hood 1 is also improved.

Further, in the present embodiment, the direction of the corrugated cardboard of the inner member 20 is substantially parallel to the second fold line 20a, the second sub fold line 20b and the intermediate fold line 20e, and further, the second fold line 20a and the second sub fold line 20a. Perforations are provided on the 20b and the intermediate crease line 20e to increase the flexibility of the inner upper wall portion 21 so that the inner member 20 easily fits on the top of the wearer's head. As a result, the disaster prevention hood 1 is also excellent in wearing comfort.

Next, a modified example of the disaster prevention hood 1 will be described. 6A to 6D and 7A and 7B are schematic views showing a modified example of the disaster prevention hood 1. 6A to 6D are views (front view) of the outer upper wall portion 11 and the inner upper wall portion 21 as viewed from the front, and the description of the rear wall portion 23 is omitted. 7A and 7B are perspective views seen from the front side.

FIG. 6A shows an example in which two intermediate crease lines 20e are added to the inner upper wall portion 21. The number and position of the intermediate fold lines 20e are not particularly limited, and the fit and comfort of the disaster prevention hood 1 can be adjusted by appropriately setting these. Further, the intermediate fold line 20e is limited to one substantially parallel to the second fold line 20a and the second sub fold line 20b as long as it is provided so as to connect the front end edge and the rear end edge of the inner upper wall portion 21. However, it may be provided in a direction intersecting these.

FIG. 6B shows an example in which two first fold lines 10a are provided on the outer member 10. In this way, by providing the two first fold lines 10a at the positions corresponding to the thicknesses of the outer member 10 and the inner member 20, the outer upper wall portion 11 and the outer side wall portion 12 are substantially parallel to each other when folded. Therefore, it is possible to further improve the storage capacity of the disaster prevention hood 1. Similarly, the inner member 20 may be provided with two second fold lines 20a, or may be provided with two second vertical fold lines 20d.

FIG. 6C shows an example in which the inner member 20 is fixed to the outer member 10 by substantially matching the first sub-fold line 10b and the second sub-fold line 20b. The position of the second sub-fold line 20b with respect to the first sub-fold line 10b is not particularly limited, and may be arranged so as to be substantially aligned with the first sub-fold line 10b in this way.

If the inner side wall portion 22 does not overlap with the outer upper wall portion 11, the disaster prevention hood 1 can be opened so that it can be worn, and the inner side wall portion 22 does not overlap with the outer upper wall portion 11. The second sub-fold line 20b can be arranged at any position within the range. By appropriately setting the position of the second sub-fold line 20b together with the dimension a2 of the inner upper wall portion 21, the size of the gap between the outer upper wall portion 11 and the inner upper wall portion 21 can be adjusted.

FIG. 6D shows an example in which the inner side wall portion 22 is omitted. In this example, the inner upper wall portion 21 is provided with the third sub-fold line 20f substantially parallel to the second fold line 20a, and the upper adhesive piece 26 is connected to the inner upper wall portion 21 via the third sub-fold line 20f.
