Abstract

[Problem] To provide a simple helmet which requires as little storage space as possible, and which can be quickly set to a usable state. [Solution] This simple helmet (1) is provided with: a thick plate member (3) that has a through hole (2) into which a human head can fit; a telescopic cylinder (4) that is telescopically accommodated inside the through hole (2) of the thick plate member (3), and has one end side held on the inner peripheral surface of the through hole (2) and the other end side capable of extending upward from the upper surface of the thick plate member (3); and a protective plate (5) that is provided on the other end side of the telescopic cylinder (4) so as to cover the through hole (2), and mitigates external impacts. Accordingly, when normally not in use, the telescopic cylinder (4) is accommodated in a shortened state inside the through hole (2) of the thick plate member (3); however, when in use, the head (10) enters the lower opening of the through hole (2) while the thick plate member (3) is pressed downward, such that the telescopic cylinder (4) is immediately extended upward and the head (10) is inserted into the extended telescopic cylinder (4).

Description

Simple helmet

The present invention relates to a simple helmet that can be stored and stored without being bulky and can quickly protect a human head in the event of a disaster.

In recent years, taking into account disasters such as earthquakes, there is a tendency to prepare and store helmets made of metal or reinforced plastic. This is because wearing a helmet can protect the user's head in the event of a disaster such as an earthquake. However, the helmet has a size slightly larger than the human head, and a storage space corresponding to the size of the helmet is required for storage. In particular, when the number of helmets to be stored is large, a relatively large storage space is required even if the helmets are stored repeatedly.

For this reason, in consideration of the above points, a simple helmet has been proposed in which it is normally folded (when not in use) into a flat plate shape and assembled into a three-dimensional hemispherical polyhedron when used (Patent Document) 1). According to this, since it is folded into a flat plate shape when not in use, the storage space can be reduced and portability can be provided.

JP 2009-062664 A

However, in the above-mentioned simple helmet, it must be assembled from the folded state at the time of use, and it is highly necessary to protect the head quickly, while it is difficult to assemble in the event of a disaster that is difficult to keep calm. It is not preferable to work.

The present invention has been made in view of the above circumstances, and a technical problem thereof is to provide a simple helmet that can reduce the storage space as much as possible and can be quickly put into use.

In order to achieve the above technical problem, the present invention (the invention according to claim 1)
A thick plate material that has a through-hole through which a person's head can enter and that protrudes from the through-hole to the periphery while partitioning the through-hole;
The thick plate material is retractably accommodated in the through hole, and one end side is held by the inner peripheral surface of the through hole, while the other end side is outside the thick plate material from one side surface in the thickness direction. A telescopic cylinder that can be extended toward
A protective member that is provided on the other end side of the telescopic cylinder so as to cover the through-hole and relieves an impact from the outside;
Equipped with,
It is set as the simple helmet characterized by this. The preferred embodiment of claim 1 is as described in claim 2 and the following.

According to the present invention (the invention according to claim 1), when not in use, the telescopic tube can be stored in a shortened state in the through-hole of the thick plate material, and as a whole, approximately one piece thick. Can be put together in a board. On the other hand, in use, if the thick plate material is pushed down while the head is put into the through hole from the other side in the thickness direction of the thick plate material, the telescopic cylinder is immediately The head extends into one side in the thickness direction, and the head enters the expanded telescopic cylinder, and the head is protected by the protective member. For this reason, while being able to reduce a storage space as much as possible, the simple helmet which can be used quickly can be provided.

According to the second aspect of the present invention, the protective member is formed in a plate shape, and the peripheral portion of the plate-shaped protective member is brought into contact with the peripheral portion of the through hole when the telescopic cylinder is shortened. Since it is set, the protective member functions as a lid or stopper when the telescopic cylinder is shortened, and the telescopic cylinder can be accurately stored in the through hole of the thick plate material.
Moreover, since the protective member is plate-shaped, it is possible to suppress as much as possible the increase in the overall thickness in the thickness direction of the thick plate material when the telescopic cylinder is stored in the through hole.

According to the invention of claim 3, since the thickness of the protective member is set so as to increase inward in the radial direction, an impact from the outside is effectively suppressed while suppressing the thickness of the protective member as much as possible. Can be relaxed (absorbed). For this reason, the whole thickness can be suppressed as much as possible when not in use, and when used, the impact from the outside can be effectively relieved and the role as a helmet can be accurately achieved.

According to the invention which concerns on Claim 4, it is formed so that a through-hole may be diameter-expanded as it goes to the thickness direction other side of a thick plate material from the thickness direction one side of a thick plate material, and the thickness of the thick plate material in a through hole Since the opening on the other side in the thickness direction is set to a size that can store the protective member, if the simple helmet is stacked with the normal form not in use, the protective member of the simple helmet on the lower side is the upper side. It is housed in the through-hole of the simple helmet and can be stacked many times with almost no inclination. For this reason, the said simple helmet can be stored efficiently and storage space can be reduced.

According to the invention which concerns on Claim 5, it is set so that a chin string may be provided in a thick board material, a chin string may be length-adjustable, and it may be used also in order to press a protection member against a thick board material. Thus, the protective member and the telescopic cylinder can be reliably prevented from popping out unintentionally, and can be kept in a substantially thick plate state at all times when not in use.

According to the sixth aspect of the present invention, the cloth tube material is disposed on the outer peripheral side of the expandable tube so as to surround the entire periphery of the expandable tube when the expandable tube is extended, and the outer periphery on one end side of the cloth tube member is in the through hole. It is attached to the peripheral surface on the outer peripheral side of the telescopic cylinder, and the other end side of the cloth tubular material is attached to the inner peripheral edge of the protective member. The head can be protected by the telescopic tube and the cloth tube material against scattered matters from the outside side. In addition, since the tubular material is made of cloth, the appearance can be improved and a soft feeling can be produced.

According to the invention of claim 7, since the expansion and contraction cylinder is configured to hold a plurality of cylinders so as to be slidable in a telescopic manner, the expansion cylinder is specifically designed to suppress expansion resistance as much as possible during expansion. Can be provided.

According to the invention of claim 8, the thick plate material is formed in a rectangular shape in plan view, the through hole is opened in an elliptical shape in plan view, and the long axis of the elliptical opening in the through hole is the longitudinal direction of the thick plate material In addition, since the minor axis of the elliptical opening in the through hole is oriented in the width direction of the thick plate material, it is easy to handle and store in a rectangular shape in plan view when it is not used normally. A plate-like material can be used, and when used, a thick plate-like material having a rectangular shape in plan view can be used as a basic part and function properly as a helmet.

According to the ninth aspect of the present invention, since the inner surface of the protective member is provided with the buffer material in the telescopic cylinder, the influence of the impact force on the human head during use can be further reduced.

Embodiments of the present invention will be described below with reference to the drawings.
1 to 6, reference numeral 1 denotes a simple helmet according to the embodiment. The simple helmet 1 is protected as a protective member that covers the thick plate material 3 having the through hole 2, the telescopic cylinder 4 accommodated in the through hole 2 of the thick plate material 3, and the through hole 2 of the thick plate material 3. And a plate 5.

As shown in FIGS. 1 to 4, the thick plate material 3 is integrally formed using a resin having excellent impact resistance such as ABS resin so as to be a rectangular thick plate in plan view. Specifically, the thickness of the thick plate 3 is sufficiently longer than the length of the human head in the front-rear direction (for example, the length of each long side of the B5, A4, and B4 sheets) and the width thereof. The length of the direction is somewhat longer than the length of the human head in the left-right direction (for example, the length of each short side of B5, A4, B4 paper), and the thickness is relatively thick due to the relationship with the required strength. It is formed (for example, about 3 to 5 cm). In the thick plate material 3, the through-hole 2 is formed with an elliptical opening at the center in the longitudinal direction and the width direction of the thick plate material 3 so that the human head can be accurately inserted. ing. In the through hole 2, the long axis of the elliptical opening in the through hole 2 is directed in the longitudinal direction of the thick plate member 3, and the short axis of the elliptical opening is directed in the width direction of the thick plate member 3. Thereby, the longitudinal direction of the thick plate material is the front-rear direction during use (when the human head is stored), and the width direction of the thick plate material is the left-right direction during use. Further, the thick plate material 3 has one side surface in the thickness direction as an upper surface, and the other side surface in the thickness direction of the thick plate material 3 is a lower surface, and the through holes 2 gradually increase from the upper surface to the lower surface of the thick plate material 3. The diameter is set to be expanded. In addition, at least the lower portion of the through hole 2 is secured in the longitudinal direction of the human head in the longitudinal direction of the thick plate member 3, and the horizontal length of the human head in the width direction of the thick plate member 3. Is secured.

As shown in FIGS. 4 to 6, the telescopic cylinder 4 has a structure (telescopic) in which a plurality of overlapping cylinders 4a expand and contract (slide). The telescopic cylinder 4 is also formed in an elliptical shape with the cylindrical opening corresponding to the through hole 2, and the human head can be stored in the telescopic cylinder 4. The length of each cylinder 4a in the telescopic cylinder 4 in the axial direction is formed to be a thickness of the thick plate 3 or slightly shorter than that, and the cylinder 4a on the base end side (FIG. 4 to FIG. 4). In FIG. 6, the outer peripheral surface of the lowermost cylinder 4 a) is attached to the inner peripheral surface of the through-hole 2 without protruding outward in the axial center extending direction of the through-hole 2. For this reason, the telescopic cylinder 4 is completely accommodated in the through hole 2 when shortened (see FIG. 4), and each cylinder 4a on the distal end side of the base end side cylinder 4a is the upper surface of the thick plate 3 when extended. It is supposed to extend in a direction away from. As each cylinder 4a of this expansion-contraction cylinder 4, the thing made from nylon is used, for example.

As shown in FIGS. 1 to 6, the protective plate 5 is attached to the distal end portion of the telescopic cylinder 4 so as to cover the distal end opening of the telescopic cylinder 4. The protective plate 5 is set so that the lower surface of the peripheral edge thereof is in contact with the upper surface of the peripheral edge of the upper opening of the through hole 2 when the telescopic cylinder 4 is shortened (see FIG. 4). Corresponding to the opening of the through hole 2, it is formed in an elliptical shape. The protective plate 5 has an inner surface (lower surface) formed flat, while the thickness of the protective plate 5 is set so as to increase inward in the radial direction (for example, the maximum thickness). Is about 3 mm to 1 cm), and the impact mitigation ability (impact absorption ability) is enhanced toward the inner side in the radial direction. Moreover, in the present embodiment, as the material for the protective plate 5, a material having excellent impact resistance, such as ABS resin, is used. In addition, a buffer material 6 is attached to the inner surface of the protective plate 5 so as to reduce the impact force. Various materials can be used as the buffer material 6, but a material composed of three layers of an ABS resin layer, a styrene foam layer, and a urethane layer is preferable from the viewpoint of securing buffer properties.

Between the protective plate 5 and the thick plate member 3, as shown in FIGS. 4 to 6, a cloth tubular member 7 is provided. The cylindrical member 7 is also formed corresponding to the through hole 2, and the outer periphery on one end side is attached to the inner peripheral surface of the through hole 2 on the outer peripheral side of the base end side cylindrical body 4 a in the telescopic tube 4. An end is attached to the inner surface of the peripheral edge of the protective plate 5. Thereby, the cloth cylinder 7 is in a state in which the expansion / contraction cylinder 4 is always stored therein, and the cloth cylinder 7 is stored in the through hole 2 together with the expansion / contraction cylinder 4 when the expansion / contraction cylinder 4 is shortened. When the tube 4 is extended, the tube 4 is extended together with the telescopic tube 4 above the upper surface of the thick plate member 3. As the cloth cylinder 7, a strong cloth such as a fireproof nylon is used.

The chin cord 8 is attached to the thick plate member 3 as shown in FIGS. 1 to 3 and FIG. The chin cord 8 is attached to both sides in the width direction of the thick plate material 3 at the center in the longitudinal direction of the thick plate material 3, and the chin cord 8 is hung between both sides of the thick plate material 3 in the width direction. Has been passed. A one-touch buckle 9 is interposed in the middle of the chin cord 8, and the one-side string portion 8 a and the other-side string portion 8 b of the chin-string 8 are connected by the male and female fittings in the one-touch buckle 9. Are detachably connected. The chin string 8 can be adjusted in overall length by adjusting the connecting position of the one-side string portion 9a or the other-side string portion 9b with respect to the one-touch buckle 9.

In such a simple helmet 1, when not in use, the telescopic cylinder 4 is housed in a shortened state in the through hole 2 of the thick plate member 3 as shown in FIGS. The part is brought into contact with the upper surface of the upper opening periphery of the through hole 2, and the through hole 2 is covered with the protective plate 5. Then, as shown in FIG. 1, the chin cord 8 is stretched over the both sides in the width direction of the thick plate material 3 via the upper surface side, and the protection cord is held by the chin cord 8 by adjusting the length of the chin cord 8. 5 is pressed against the upper surface of the peripheral edge of the upper opening of the through hole 2. For this reason, in the normal time when it is not used, the telescopic cylinder 4 and the like can be prevented from inadvertently protruding from the thick plate material 3, and the entire shape can be compactly combined into a single thick plate material 3.

Moreover, in the present embodiment, the lower opening of the through hole 2 in the thick plate member 3 is made larger than the upper opening thereof, and the size of the opening is set to a size that can accommodate the protective plate 5. As shown in FIG. 7, when the normal simple helmet 1 (the state of the thick plate material 3) that is not used is stacked, the protective plate 5 and the chin cord 8 in the simple helmet 1 on the lower side are the simple helmet 1 on the upper side. The stacked simple helmets 1 can be stacked in an orderly manner with almost no inclination. Thereby, even if it is a limited storage space, many simple helmets 1 can be stored efficiently.

At the time of use, after removing the male metal fitting and female metal fitting from the one-touch buckle 9 in the chin string 8, hold the thick plate material 3 of the simple helmet 1 and hold the head 10 in the lower opening of the through hole 2. While facing it, the thick plate member 3 is pushed down against the head 10 (see FIG. 5). As a result, the head 10 pushes up the protective plate 5, and accordingly, as shown in FIG. 5, the telescopic cylinder 4 is extended upward, and the user's head 10 is placed in the telescopic cylinder 4. Enters. For this reason, the simple helmet 1 can be immediately put into use without performing assembly work. Thereafter, the user's head 10 is protected by the protective plate 5, the telescopic cylinder 4, and the cloth cylinder 7 of the simple helmet 1. Can be protected.

In this way, after the simple helmet 1 is put on the head 10, the length of the chin cord 8 is adjusted as necessary, and then the one-side string portion 8 a and the other-side string portion 8 a are adjusted by the one-touch buckle 9. The string portion 8b is connected to prevent the simple helmet 1 from coming off the head 10. Of course, the length of the chin cord 8 is preferably adjusted in advance.

Although the embodiments have been described above, the present invention is not limited to the embodiments and includes the following aspects.
(1) A bellows type cylinder is used as the telescopic cylinder 4.
(2) The cloth cylinder 7 is not necessarily required, and the cloth cylinder 7 may be omitted and only the telescopic cylinder 4 may be provided.
(3) The protective plate 5 is formed in a curved shape having a thickness of about 3 mm, and the buffer material 6 is provided in the curved protective plate 5 so that the amount (the thickness in the vertical direction) of the buffer material 6 is in the center. Make it thicker.

The object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage.
