FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1; FIG. 2 is a perspective view of the safety helmet shown in FIG. 1 as viewed diagonally from the rear; Fig. 2 is a perspective view showing a state in which the safety helmet shown in Fig. 1 is folded;

Embodiments of the present invention will be exemplified below with reference to the drawings.

As shown in FIGS. 1 to 3, in one embodiment of the present invention, a safety helmet 1 is worn on the head to absorb external impacts on the head and suppress the occurrence of injuries. . That is, the safety helmet 1 can be used, for example, as a simple helmet, a hat for light work, a hat for disaster prevention, or the like.

A safety helmet 1 has a crown 2 and a brim 3. The crown 2 is formed of a semi-cylindrical peripheral surface portion 4 and a pair of end surface portions 6 that are connected to both ends of the peripheral surface portion 4 in the cylinder axis direction via ridgeline portions (hereinafter also referred to as end ridgeline portions 5). . In the present application, the axial direction, the radial direction, and the circumferential direction of the semi-cylindrical peripheral surface portion 4 are also simply referred to as the axial direction, the radial direction, and the circumferential direction.

The peripheral surface 4 is formed by a pair of upper square panels 7 and a pair of lower square panels 8 . Each of the end faces 6 is formed by a pair of upper tapered panels 9 and a pair of lower tapered panels 10 . Each of the upper tapered panel 9 and the lower tapered panel 10 tapers radially inwardly.

The ridgeline portion passing between the pair of upper rectangular panels 7 and between the pair of upper tapered panels 9 on each of the end faces 6 forms a valley-fold ridgeline portion 11 that can be valley-folded as shown in FIG. Configure.

Between the upper rectangular panel 7 and the lower rectangular panel 8 on each of the circumferential sides of the valley fold ridge 11, and between the upper tapered panel 9 and the lower tapered panel 10 on each of the end faces 6. , constitutes a mountain-folded ridge-line portion 12 capable of mountain-folding as shown in FIG.

In each of the end face portions 6 , a ridgeline portion (hereinafter also referred to as a tip ridgeline portion 13 ) passes vertically between the tip edges of the pair of lower tapered panels 10 .

Each of the upper square panel 7, lower square panel 8, upper tapered panel 9 and lower tapered panel 10 has a cushioning material 14, more specifically an outer material 15, a cushioning material 14 and a lining material 16. in this order (see FIG. 2). The material of the cushioning material 14 is not particularly limited, and may be made of, for example, foamed resin. The material of the outer material 15 and the lining material 16 is not particularly limited, and is composed of, for example, cloth, non-woven fabric, mesh material, or the like.

Each of the upper quadrangular panels 7 is formed of a pair of quadrangular panels 18 connected via a ridgeline portion (hereinafter also referred to as an intermediate ridgeline portion 17) (see FIG. 1).

Each of the ridges does not have cushioning material 14 . That is, each of the end ridgeline 5, the valley-fold ridgeline 11, the mountain-fold ridgeline 12, the tip ridgeline 13, and the intermediate ridgeline 17 does not have the cushioning material 14. The linings 16 are adhered to each other without the cushioning material 14 (see FIG. 2). The method of fixation is not particularly limited, and is suture, for example.

The brim 3 is provided corresponding to one of the pair of lower quadrangular panels 8 (see FIG. 1).

According to this embodiment, the safety helmet 1 can be put on the head as shown in FIG. While deforming the crown 2 so that the lower quadrangular panels 8 approach each other as indicated by the white arrows, the valley-folded ridgeline portion 11 is brought into the valley-folded state, and each of the pair of mountain-folded ridgeline portions 12 is folded into a mountain. As a result, a compact folded state as shown in FIG. 4 can be obtained.

Further, according to the present embodiment, each of the end face portions 6 has the tip ridge line portion 13, so that the cushioning material 14 can be densely arranged near the tip ends of the pair of lower tapered panels 10 on each of the end face portions 6. and, as a result, increased safety.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.

Therefore, the safety helmet 1 of the embodiment described above has a crown 2 formed of a semi-cylindrical peripheral surface portion 4 and a pair of end surface portions 6 connected to both ends of the peripheral surface portion 4 in the cylinder axis direction via a ridge line. The peripheral surface 4 is formed by a pair of upper square panels 7 and a pair of lower square panels 8, and the end surfaces 6 each comprise a pair of upper tapered panels 9 and a pair of lower tapered panels 10. with each of the upper tapered panel 9 and the lower tapered panel 10 tapering radially inward, and between the pair of upper square panels 7 and on each of the end faces 6 a pair of The ridge line between and through the upper tapered panel 9 constitutes a valley-fold ridge line 11 that can be valley-folded. A ridgeline portion passing between the side rectangular panels 8 and between the upper tapered panel 9 and the lower tapered panel 10 in each of the end faces 6 constitutes a mountain-folded ridgeline portion 12, A safety helmet in which each of an upper quadrangular panel 7, a lower quadrangular panel 8, an upper tapered panel 9 and a lower tapered panel 10 has a cushioning material 14, and each of ridge portions does not have a cushioning material 14. As long as it is 1, various changes are possible.

For example, the flexibility, shape, arrangement, etc. of the collar 3 can be appropriately set. The flange 3 is not limited to one of the pair of lower square panels 8, and may be provided to correspond to one of the pair of end face portions 6, for example. Also, the flange 3 may be provided over the entire circumference. A configuration in which the flange 3 is not provided may be employed. The configuration is not limited to the configuration in which each of the upper quadrangular panels 7 has the intermediate ridge line portion 17 . The configuration is not limited to the configuration in which each of the end surface portions 6 has the tip ridge line portion 13 . Each of the upper square panel 7, the lower square panel 8, the upper tapered panel 9 and the lower tapered panel 10 is not limited to having the outer material 15, the cushioning material 14 and the lining 16 in this order.

In addition, in the safety helmet 1 of the above-described embodiment, in each of the end faces 6, the ridgeline passes vertically between the leading edges of the pair of lower tapered panels 10, and the ridgeline is buffered. A hard hat 1 without material 14 is preferred. When there is the ridge line, concentration of folds of the tapered panels 9 and 10 of the safety helmet 1 can be avoided, and the helmet can be easily folded.

In the safety helmet 1 of the above-described embodiment, each of the upper quadrangular panel 7, the lower quadrangular panel 8, the upper tapered panel 9 and the lower tapered panel 10 is composed of the outer material 15, the cushioning material 14 and the A safety helmet 1 having a lining 16 in that order is preferred.

The safety helmet 1 of the embodiment described above may further have a chin strap. The chinstrap is preferably provided so that the mutually facing portions (for example, the pair of end face portions 6) of the lower edge of the crown 2 are connected via the chinstrap. When the safety helmet 1 has a chin strap, the safety helmet 1 is difficult to come off from the head, and the safety of protecting the head is enhanced.
