The following describes an embodiment of the present invention.

[First embodiment of the invention]
1 to 13 show a first embodiment of the present invention.

First, to briefly explain the configuration, the foldable hat 10 of this embodiment shown in Figure 1 is used as a foldable helmet in the event of an emergency disaster, for example, and has a structure equipped with an interior material. This foldable hat 10 comprises a hat body 10A for a foldable hat, an interior material 10B provided within this hat body 10A for a foldable hat, and a covering member 10C attached to the hat body 10A for a foldable hat equipped with this interior material 10B.

In the following embodiments, the front side of the head will be referred to as the front side, the back side of the head as the back side, and the left and right sides of the side of the head as the left and right sides, respectively, when the foldable hat 10 is worn on the user's head.

As shown in Figures 1 to 12, the hat body 10A for a foldable hat has hat body bodies 11, 11 (shown in Figure 11) that are separated into left and right sides, a strength member 20 provided on these hat body bodies 11, 11, and a reinforcing member 30 superimposed on the upper part of this strength member 20. The hat body 10A for a foldable hat can be changed between a folded state and an unfolded state that can be worn on the head.

The cap body 11, 11 shown in Figs. 10 to 12 is formed by punching out a plate-like flexible elastic material such as colored, opaque, expanded polyethylene. The cap body 11, 11 is formed from a flexible elastic material such as expanded polyethylene, and therefore has a lighter specific gravity than resins such as polypropylene, which are generally used as cap bodies and have high rigidity and high bending strength. This allows the cap body 11, 11 to be lightweight in this embodiment. The cap body 11, 11 has a thickness of, for example, about 5.0 mm. In this way, the cap body 11, 11 can be changed into both the folded state shown in Fig. 12 and the unfolded state shown in Fig. 10.

The cap body bodies 11, 11 are designed to cover both sides of the head. As shown in FIG. 11, these cap body bodies 11, 11 are formed in the same shape, approximately a long trapezoid. In addition, each cap body 11, 11 is formed in a shape that is approximately plane symmetrical in the front-to-rear direction.

As shown in FIG. 11, each of the hat body bodies 11, 11 has circular locking holes 11a at both the front and rear ends to lock the interior material 10B and the strength member 20 with the locking device 21. In addition, each of the hat body bodies 11, 11 has circular locking holes (not shown) at the front and rear of the middle position to overlap and lock the strength member 20, the reinforcing member 30, and the reinforcing plate 37 with the locking device 21.

In this embodiment, the hat body 11, 11 is configured as separate left and right halves, but this is not limiting and the left and right may be configured as an integrated unit. Even in this case, it can be easily manufactured by punching.

As shown in Figs. 1 to 6 and 8 to 12, the strength member 20 is provided on the cap body 11, extending in front of and behind the top of the head, has a strength greater than that of the cap body 11, and is provided so as to be foldable via the portion facing the top of the head. The strength member 20 has a thickness of, for example, about 3.0 mm.

The strength member 20 is detachably attached to the hat body 11. That is, the lower part of the strength member 20 is detachably attached to the hat body 11, 11 on the front and rear sides by the two locking devices 21 described above, together with the interior material 10B, etc. These locking devices 21 are integrally molded from a synthetic resin such as polycarbonate. The locking device 21 has a rod-shaped shaft with a disk portion formed at one end and a locking portion perpendicular to the shaft formed at the other end. The disk portion has a groove formed along the diameter direction in which a coin can be engaged. The locking portion is formed shorter than the opening length of the locking device insertion hole 22a of the strength member 20 described later, and is formed so that it can be inserted into the locking device insertion hole 22a. The locking portion has a chamfered corner to make it easier for the user to pinch it with his fingers and rotate it.

When the cap body 11 is attached, the side of the cap body 11 extends further in both left and right directions than the strength member 20. The strength member 20 is integrally formed into a plate shape from a synthetic resin such as foamed polypropylene, which has high rigidity, high bending strength, and is lightweight.

The strength member 20 is integrally formed with a front flat plate 22 for covering the forehead, a connecting plate 23 for covering the top of the head, and a rear flat plate 24 for covering the back of the head. In other words, the front flat plate 22 and the rear flat plate 24 are connected via the connecting plate 23.

A first hinge portion 25 is formed between the front flat plate 22 and the connecting plate 23 along the left-right direction, and a second hinge portion 26 is formed between the rear flat plate 24 and the connecting plate 23 along the left-right direction. The connecting plate 23 is formed in a rectangular shape in a plan view. The first hinge portion 25 and the second hinge portion 26 are formed along the left-right direction of the portion facing the top of the head, and the strength member 20 is configured to be foldable in the front-rear direction via the first hinge portion 25 and the second hinge portion 26.

The front flat plate 22 is formed into a roughly trapezoidal shape when viewed from the front, and fastener insertion holes 22a, 22a are provided on the left and right sides of the lower part at positions corresponding to the fastener holes 11a, 11a of each of the hat bodies 11, 11. These fastener insertion holes 22a, 22a are formed to be long in the vertical direction. One hook-and-loop fastener 27 for fastening the covering member 10C when the covering member 10C is attached to the strength member 20 is fixed by adhesion between these fastener insertion holes 22a, 22a.

Similarly, the rear flat plate 24 is formed into a generally trapezoidal shape when viewed from the front, and fastener insertion holes 24a, 24a are provided on the left and right sides of the lower part at positions corresponding to the fastener holes 11a, 11a of each of the cap bodies 11, 11. These fastener insertion holes 24a, 24a are also formed to be elongated in the vertical direction, similar to the fastener insertion holes 22a, 22a. One of the hook-and-loop fasteners 27 that fasten the covering member 10C when the covering member 10C is attached to the strength member 20 is fixed by adhesion between the fastener insertion holes 24a, 24a.

The fastener insertion holes 22a, 22a in the front flat plate 22 and the fastener insertion holes 24a, 24a in the rear flat plate 24 are formed by punching the plate material. At the same time as punching out these fastener insertion holes 22a, 22a, 24a, 24a, the first hinge portion 25 and the second hinge portion 26 are also formed.

The covering member 10C is made of a foldable, flame-retardant material, such as a fabric surface coated with aluminum. In this embodiment, the covering member 10C is integrally formed with the hood portion 12 and the brace portion 13. The hood portion 12 is formed in an inverted V-shape in cross section. The hood portion 12 is formed in a three-dimensional shape that fits the shapes of the strength member 20 and the reinforcing member 30 formed when the foldable hat 10 is in an unfolded state and worn on the head. The brace portion 13 is formed in an approximately fan-like shape.

The covering member 10C has a hook-and-loop fastener 27 attached to both the front and back of the hood portion 12, the hook-and-loop fasteners 27 being connectable to the hook-and-loop fasteners 27 attached to the front and back flat plates 22 and 24 of the strength member 20, respectively. This allows the covering member 10C to be detachably attached to the strength member 20 via the hook-and-loop fasteners 27. When the hood portion 12 of the covering member 10C is fastened to the strength member 20, the brace portion 13 of the covering member 10C spreads out to cover the back of the user's head and around the neck.

The front flat plate 22 has vertically long fastener insertion holes (not shown) at the upper left and right sides, through which the fasteners 21 pass. Similarly, the rear flat plate 24 has vertically long fastener insertion holes (not shown) at the upper left and right sides, through which the fasteners 21 pass.

As shown in Figs. 5 and 11, a cushioning member 28 is fixed by adhesive to the portion of the strength member 20 facing the top of the head, i.e., the inner surface of the connecting plate 23. This cushioning member 28 is made of polystyrene foam and is integrally formed into a convex shape in side view. The cushioning member 28 is formed so that its width is approximately the same as the width of the inner surface of the connecting plate 23, its length is slightly shorter than the length of the inner surface of the connecting plate 23, and its height reaches near the top of the head when the foldable hat 10 is worn by the user.

Since the cushioning member 28 is integrally formed with a convex shape in a side view, its strength in the vertical direction is significantly increased. Therefore, even if the cushioning member 28 comes into contact with the top of the head due to the impact of a falling object or the like during an emergency disaster, it can cushion the top of the head and reliably protect the head.

The strength member 20 is the inner surface near the lower end of the front flat plate 22 and the rear flat plate 24, and between the cap body 11, 11, plate materials 29, 29 having both gap blocking and buffering functions are fixed with adhesive. When the interior material 10B is attached to the strength member 20, these plate materials 29, 29 form a narrow gap between the strength member 20 and the interior material 10B and between the cap body 11, 11. Therefore, the gap is blocked by the plate materials 29, 29 to prevent the user's fingers from entering. In this case, the inner edge portions of the lower ends of the front flat plate 22 and the rear flat plate 24 may be formed sharp by molding. Therefore, by preventing the user's fingers from entering, safety can be increased.

The plate members 29, 29 are formed in a rectangular shape, are made of the same material as the cap body 11, 11, and have a thickness of, for example, about 5.0 mm. Therefore, the plate members 29, 29 serve as cushioning members near the lower ends of the front flat plate 22 and the rear flat plate 24.

The reinforcing member 30 is provided on the upper surface of the strength member 20 in an overlapping manner. Specifically, a reinforcing front plate 32, a reinforcing connecting plate 33, and a reinforcing rear plate 34 are provided on the upper side of the front plate 22, the connecting plate 23, and the rear plate 24, respectively. The reinforcing member 30 is integrally formed with the reinforcing front plate 32 for covering the forehead, the reinforcing connecting plate 33 for covering the top of the head, and the reinforcing rear plate 34 for covering the rear of the head.

That is, the reinforcing front plate 32 and the reinforcing rear plate 34 are connected via the reinforcing connecting plate 33. The reinforcing member 30, like the strength member 20, is integrally formed into a plate shape from a synthetic resin such as foamed polypropylene that has high rigidity and high bending strength, and has a thickness of, for example, about 3.0 mm.

Since the reinforcing front plate 32 and the reinforcing rear plate 34 are overlapped on the upper side of the front plate 22 and the upper side of the rear plate 24, respectively, the reinforcing connecting plate 33 is formed wider by the plate thickness of the front plate 22 and the rear plate 24. The reinforcing front plate 32 is formed in a generally trapezoidal shape when viewed from the front, and its vertical length is less than half the length of the front plate 22. Similarly, the reinforcing rear plate 34 is also formed in a generally trapezoidal shape when viewed from the front, and its vertical length is less than half the length of the rear plate 24.

A third hinge portion 35 is formed between the reinforcing front flat plate 32 and the reinforcing connecting plate 33 along the left-right direction, and a fourth hinge portion 36 is formed between the reinforcing rear flat plate 34 and the reinforcing connecting plate 33 along the left-right direction. The reinforcing connecting plate 33 is formed in a rectangular shape in a plan view, similar to the connecting plate 23.

On the left and right sides of the reinforcing front flat plate 32, there are provided fastener insertion holes (not shown) through which the fasteners 21 are inserted. Similarly, on the left and right sides of the reinforcing rear flat plate 34, there are provided fastener insertion holes (not shown) through which the fasteners 21 are inserted. These fastener insertion holes are formed in the same positions as the fastener insertion holes of the strength member 20 and are in communication with each other, and the same fasteners 21 are inserted into each of them.

The fastener insertion holes in the reinforcing front plate 32 and the reinforcing rear plate 34 are formed by punching the plate material, similar to the strength member 20. As with the strength member 20, the third hinge portion 35 and the fourth hinge portion 36 are also formed at the same time as punching these fastener insertion holes.

A reinforcing plate 37 made of a white, opaque synthetic resin such as polycarbonate is superimposed on the reinforcing front plate 32. The reinforcing plate 37 has a thickness of, for example, about 3.0 mm. The reinforcing plate 37 has a larger radius at the upper corner than at the lower corner, and is otherwise formed in substantially the same shape as the reinforcing front plate 32.

Similarly, a reinforcing plate 37 made of a white opaque synthetic resin such as polycarbonate is superimposed on the reinforcing rear plate 34. This reinforcing plate 37 has the same structure as the one superimposed on the reinforcing front plate 32, and is attached in a symmetrical position to the reinforcing plate 37 of the reinforcing front plate 32.

The reinforcing plates 37, 37 provided on the reinforcing front plate 32 and the reinforcing rear plate 34 are curved so that the central portions of the reinforcing plates 37, 37 protrude slightly in the length direction. Therefore, a plurality of reinforcing ribs 37a that abut against the reinforcing front plate 32 and the reinforcing rear plate 34 are formed on the back side of the reinforcing plates 37, 37.

On the left and right sides of the reinforcing plate 37, there are provided fastener insertion holes through which the fasteners 21 are inserted, at the same positions on the left and right as the fastener insertion holes of the cap body 11, 11 and the fastener insertion holes provided on the left and right sides of the front flat plate 22 and the reinforcing front flat plate 32. Around these fastener insertion holes, recesses 37b are formed so that the fasteners 21 do not protrude from the upper surface of the reinforcing plate 37 when the fasteners 21 are attached.

In this way, in the hat body 10A for a foldable hat of this embodiment, the hat body main bodies 11, 11 are formed of a plate-like elastic material having flexibility, and on these hat body main bodies 11, 11, a plate-like strength member 20 is provided extending in the front-to-rear direction of the top of the head, and since it has a higher strength than the hat body main bodies 11, 11, it is possible to maintain a high strength.

In addition, because the hat body 11, 11 is made of a flexible elastic material, it is possible to achieve a lighter weight compared to resin, which has high rigidity and strength. And because the strength member 20 extends in the front-to-back direction of the top of the head, it is possible to prevent impacts from falling objects, etc.

In addition, in the present embodiment, the hat body 10A for a foldable hat is formed by forming the hat body 11 and the strength member 20 into a plate shape, so that it can be easily formed by punch molding without using a molding device with a metal mold.

In the present embodiment, the hat body 10A for a foldable hat is constructed of multiple overlapping plate members 20 at least in the portion facing the top of the head, making it possible to prevent impacts from falling objects, etc.

In the present embodiment, the hat body 10A for a foldable hat has the strength member 20 attached to the hat body 11, and the side of the hat body 11 extends laterally beyond the strength member 20, so that the side of the hat body 11 can also be protected from falling objects by the side-extending hat body 11.

In the foldable hat body 10A of this embodiment, the strength member 20 has a first hinge portion 25 and a second hinge portion 26 formed along the left-right direction of the portion facing the top of the head, and is configured to be foldable in the front-rear direction via these first hinge portion 25 and second hinge portion 26. Therefore, when a user puts on the foldable hat 10, the foldable hat body 10A is maintained in an unfolded state. This allows the foldable hat body 10A to be easily unfolded from a flat state, making it possible to provide a foldable hat body 10A that is highly convenient in the event of a disaster.

In the present embodiment, the cap body 10A for a foldable hat has a shock-absorbing member 28 fixed to the portion of the strength member 20 that faces the top of the head, which can further prevent impacts from falling objects, etc.

In this embodiment, the strength member 20 is detachably attached to the cap body 11, so that the strength member 20 and the cap body 11 can be molded separately. This makes manufacturing easier.

The hat body 10A for a foldable hat of this embodiment further includes a flame-retardant covering member 10C that is detachably attached to the strength member 20 and covers the entire hat body 11 and strength member 20, so that the user's head and neck can be reliably protected from heat and flames even in high-temperature environments such as fires.

Specifically, when the hood portion 12 of the covering member 10C is engaged with the strength member 20, the brace portion 13 covers the back of the user's head and around the neck, providing protection from heat and flames to the user's head and around the neck.

In the present embodiment, the hat body 10A for a foldable hat has hat bodies 11, 11 separated on both the left and right sides, which are formed to have the same shape, reducing the number of different parts and reducing manufacturing costs.

Next, we will explain the interior material 10B used as the interior material for hats in this embodiment.

As shown in Figures 2 to 5, the interior material 10B is attached to the inside of the hat body 10A for the foldable hat and holds the head when the user wears the foldable hat 10. The interior material 10B includes an interior material main body 40, a chin strap member 50 connected to the interior material main body 40, a back of the head holding member 54 through which the chin strap member 50 passes, and a cross string 56 (shown in Figures 7 and 8).

The interior material body 40 is formed integrally by punching from a plate-like flexible elastic material such as colored, opaque, expanded polyethylene. Therefore, the interior material body 40 can be changed between a folded state and an unfolded state. The interior material body 40 has a thickness of, for example, about 5.0 mm, similar to the cap body bodies 11, 11. The interior material body 40 uses a plate material of the same material as the cap body bodies 11, 11.

The interior material body 40 is made of a flexible elastic material such as polyethylene foam, and therefore has a lighter specific gravity than synthetic resins with a certain degree of rigidity such as headbands that are provided as part of general interior materials. This allows the interior material body 40 to be made lighter in weight in this embodiment.

As shown in FIG. 7, the interior material body 40 is integrally formed to cover the front and back of the head, and is formed with a shape that is symmetrical in left and right planes. As shown in FIG. 8, the interior material body 40 is folded from approximately the middle of its length in the front-to-back direction, excluding the eaves portion described below, and both left and right ends of the folded material are fixed by fasteners 42. Therefore, as shown in FIG. 13, the interior material body 40 is formed into a front interior material 43 for covering the front of the head and a rear interior material 44 for covering the back of the head. This allows the interior material body 40 to be folded in the front-to-back direction.

The front interior material 43 is integrally formed with a bulging eaves 45 as shown in Figs. 1 to 7. When the interior material 10B is attached to the hat body 10A for a foldable hat, the eaves 45 is attached so as to protrude forward from the strength member 20. As shown in Fig. 7, an opening 43a that is long in the left-right direction is formed on the top side of the front interior material 43. As shown in Fig. 7, an opening 43c that is approximately trapezoidal is formed in the approximate center of the rear interior material 44. An elliptical opening 43b larger than the openings 43a and 43b is formed in a position facing the top of the head between the front interior material 43 and the rear interior material 44. All of these openings 43a, 43b, and 43c function as air vents.

The buffer plate 46 is formed in a substantially rectangular shape and abuts against the forehead, and is provided at the inner center of the front interior material 43, closer to the top of the head than the visor portion 45. Specifically, one side of a hook-and-loop fastener (not shown) is adhered to the inner center of the front interior material 43, and the other side of the hook-and-loop fastener (not shown) is adhered to the middle of the length of the buffer plate 46, and the buffer plate 46 is detachably attached to the front interior material 43 by joining these hook-and-loop fasteners. When the interior material 10B is attached to the hat body 10A for a foldable hat and the user puts on the foldable hat 10, the buffer plate 46 is attached to the inner surface of the front interior material 43 in a position facing the forehead of the user.

As shown in Figures 4 and 5, the front interior material 43 is provided with cord locking members 47 near the left and right sides of the buffer plate 46, through which the connecting cord 51 is inserted and locked. Similarly, the rear interior material 44 is provided with cord locking members 47 near the left and right sides of the rear end, through which the connecting cord 51 is inserted and locked.

These four cord locking members 47 are each integrally molded from a synthetic resin such as polypropylene. As shown in FIG. 5, each of the four cord locking members 47 has locking teeth 47a formed on the inside for locking the connecting cord. When the connecting cord is pulled laterally, the locking teeth 47a of the four cord locking members 47 bite into the connecting cord to prevent it from coming loose. Therefore, when adjusting the length of the connecting cord, the connecting cord is pulled out in a direction in which it is not locked by the locking teeth 47a of the cord locking members 47.

As shown in FIG. 8, the front interior material 43 and the rear interior material 44 have fasteners 21 fixed to the inside of the four string fastening members 47 in the left-right direction. These four fasteners 21 secure the interior material main body 40, the hat body main bodies 11, 11, and the strength members 20 in a stacked manner.

As shown in Figs. 1 to 5, semicircular cutouts 49 are formed around the attachment positions of the four fasteners 21 on the front interior material 43 and the rear interior material 44. These cutouts 49 are formed on the outside of the four fasteners 21 on the front interior material 43 and the rear interior material 44. As a result, the four cutouts 49 make it possible to easily curve and deform the front interior material 43 and the rear interior material 44 on the outside of each fastener 21 inward.

As shown in Figures 1 to 5, the chin strap member 50 is hooked onto the user's chin to hold the head within the interior material body 40. The chin strap member 50 comprises a pair of connecting cords 51, 51 that are crossed and connected within the interior material body 40, a chin locking cord 52, and a cord stopper 53. The pair of connecting cords 51, 51, the chin locking cord 52, and the cross cord 56 are formed in a belt shape from synthetic resin fibers that are highly rigid and flexible.

The rear head holding member 54 is made of the same material as the buffer plate 46 and is formed in a generally V-shape as shown in Figs. 3 and 4. The rear head holding member 54 has end insertion holes 54a, 54a formed in the width direction near both ends, and a central insertion hole 54b formed in the length direction in the middle. One of the pair of connecting cords 51, 51 is inserted into each end insertion hole 54a, 54a.

As shown in FIG. 4, the pair of connecting strings 51, 51 are inserted through the central insertion hole 54b so that they cross each other. A square ring portion 55 is fixed to the front opening end of the central insertion hole 54b. When the foldable hat 10 is worn, the pair of connecting strings 51, 51 slide, and a friction load is applied to the opening end of the central insertion hole 54b. Therefore, by fixing the square ring portion 55 to the opening end of the central insertion hole 54b, the opening end is reinforced, and can be protected against friction caused by the sliding of the pair of connecting strings 51, 51. As a result, the durability of the back head holding member 54 can be increased.

The corner ring 55 is colored a different color than the back of the head retaining member 54 and is located at the front opening of the central insertion hole 54b, making it easy to see the front and rear directions when wearing the foldable hat 10.

Of the pair of connecting cords 51, 51, one connecting cord 51 has one end inserted through the left cord locking member 47 of the front interior material 43 and folded back, and the folded back portion is locked by the locking teeth 47a. The other end of one connecting cord 51 is inserted from the central insertion hole 54b of the rear head holding member 54 through the right end insertion hole 54a, and then inserted through the right cord locking member 47 of the rear interior material 44 and folded back, and the folded back portion is locked by the locking teeth 47a.

One end of the other connecting cord 51 is inserted through the left cord locking member 47 of the front interior material 43 and folded back, and then the folded back portion is locked by the locking teeth 47a. The other end of the other connecting cord 51 is inserted from the central insertion hole 54b of the rear head holding member 54 through the left end insertion hole 54a, and then inserted through the left cord locking member 47 of the rear interior material 44 and folded back, and then the folded back portion is fixed by the locking teeth 47a.

Therefore, the pair of connecting cords 51, 51 are crossed between the central insertion hole 54b of the rear head holding member 54 and the left and right end insertion holes 54a.

The chin locking cord 52 is connected to a pair of connecting cords 51, 51. The chin locking cord 52 is formed by folding back a single belt-like cord from the center. As a result, the chin locking cord 52 has two one end portions and one other end portion. Each one end of the chin locking cord 52 is wound around the left and right cord locking members 47 of the front interior material 43 of the pair of connecting cords 51, 51 and the rear head holding member 54, respectively, and fixed by a fastener 57. In addition, each other end of the chin locking cord 52 is inserted through a cord stopper 53, and then overlapped and fixed by a fastener 57. The cord stopper 53 is integrally molded from synthetic resin, and moves up and down the chin locking cord 52 to adjust the length of the fastening portion.

Therefore, when the user puts the foldable hat 10 on the head, by pulling up the string stopper 53 of the chin strap member 50, the chin is held by the chin locking string 52 and the back of the head comes into contact with the back of the head retaining member 54.

As shown in FIG. 8, the front and rear ends of two cross strings 56 are attached to the top surfaces of the front interior material 43 and the rear interior material 44. The front and rear ends of the two cross strings 56 are provided with long attachment holes 56a for fastening. These long attachment holes 56a are formed long along the length of the cross strings 56. In addition, as described above, two fasteners 21 are attached to each of the front interior material 43 and the rear interior material 44.

As shown in FIG. 8, the front and rear ends of the two cross strings 56 are respectively fastened to the fasteners 21 attached to the front interior material 43 and the rear interior material 44 through the long fastening holes 56a. The long fastening holes 56a are formed to a length that allows the fasteners 21 to move, since the relative position of the fasteners 21 differs when the foldable hat 10 is folded and when it is unfolded. The two cross strings 56 are provided so as to cross between the front interior material 43 and the rear interior material 44 at a position facing the top of the head.

The fasteners 21, two of which are attached to the front interior material 43 and the rear interior material 44, pass through the front and rear ends of the two cross strings 56, the four fastener insertion holes in the hat body 11, and then through the fastener insertion holes in the front flat plate 22 and the rear flat plate 24 of the strength member 20. This attaches the hat body 11 and the strength member 20 to the interior material body 40. In other words, the interior material 10B is attached to the hat body 10A for a foldable hat.

In the present embodiment, the interior material 10B has an interior material body 40 formed from a plate-like flexible elastic material, which allows for easy molding and manufacturing while maintaining a light weight. In addition, since the interior material body 40 is formed to cover the front and back of the head, the portion that comes into contact with the entire head is made of a flexible elastic material, which allows for a good fit when the foldable hat 10 is worn.

In the present embodiment, the interior material 10B has a foldable interior material body 40, which can be easily changed from a flat state to an unfolded state, providing a foldable hat 10 that is highly convenient in the event of a disaster.

In the interior material 10B of this embodiment, the interior material body 40 is formed with a visor portion 45 that protrudes forward of the hat body 11, providing shade outdoors and protecting the face from dust, falling objects, etc. both outdoors and indoors.

In the interior material 10B of this embodiment, a back of the head holding member 54 is attached across a pair of connecting strings 51, 51 to hold the back of the head. The string stopper 53 is pulled up to hold the chin with the chin locking string 52, and the back of the head comes into contact with the back of the head holding member 54. When putting on the foldable hat 10, the back of the head holding member 54 serves as a guide for the user in the front-to-back direction, preventing the hat from being put on backwards and providing a good fit when put on.

In the interior material 10B of this embodiment, a shock absorbing plate 46 that abuts against the forehead is further provided on the inside of the interior material main body 40 corresponding to the front position of the hat body 11, thereby protecting the forehead and improving the fit of the forehead.

In the interior material 10B of this embodiment, the buffer plate 46 is attached to the inside of the interior material main body 40 in the left-right middle at the center in the length direction, so that it can follow the shape of the interior material main body 40 when the interior material main body 40 is unfolded from a folded state. This makes it possible to further improve the fit of the forehead in the unfolded state. In addition, the buffer plate 46 is removably attached to the inside of the interior material main body 40 via a hook-and-loop fastener (not shown), so it can be easily replaced with another one.

In the present embodiment, the interior material 10B has a front end and a rear end attached to the front and rear parts of the interior material main body 40, respectively, and further includes cross strings 56 that cross on the upper side between the front and rear parts of the interior material main body 40, thereby preventing the interior material main body 40 from unfolding more than necessary and absorbing the impact of falling objects at the crossing parts.

In this case, the cushioning member 28 provided on the strength member 20 is overlapped at the intersection of the cross cords 56, so that the part of the strength member 20 facing the top of the head can be further prevented from being impacted by a falling object, etc.

In the interior material 10B of this embodiment, a cutout 49 is provided in the front interior material 43 and the rear interior material 44 around each fastener 21, so that the front interior material 43 and the rear interior material 44 on the outside of the fastener 21 can be easily curved inward.

As a result, when the user unfolds the foldable hat 10, puts it on, pulls up the string stopper 53 to hold the chin with the chin locking string 52, and pulls the pair of left and right connecting strings 51, 51, the front interior material 43 and the rear interior material 44 easily curve, and this curved portion covers both sides of the head. As a result, both sides of the user's head can be protected from falling objects, etc.

Next, we will explain the operation of the foldable hat 10 of this embodiment.

To assemble the strength member 20, reinforcing member 30, and reinforcing plate 37 to each of the cap bodies 11, 11, the locking portion of the locking device 21 is fitted into a locking hole (not shown) of each of the cap bodies 11, 11. In this case, since the cap bodies 11, 11 are made of a flexible elastic material, the locking hole can be stretched radially to fit in.

Then, after inserting the locking portion of the locking device 21 through the locking device insertion hole 22a, the locking device is inserted through the vertically long locking device insertion holes (not shown) of the strength member 20, the reinforcing member 30, and the reinforcing plate 37, and pressed until it protrudes from the bottom surface of the recess 37b of the reinforcing plate 37. With the locking portion protruding, the locking portion is rotated with the fingers to a direction approximately perpendicular to the vertical direction of the locking device insertion hole. This fixes the strength member 20, the reinforcing member 30, and the reinforcing plate 37 to each of the cap bodies 11, 11. Note that to disassemble each component, the above assembly order is reversed.

To stack and assemble the two cross strings 56, 56, the hat body 11, 11, and the strength member 20 on the interior material body 40, the locking portion of the locking device 21 is fitted into a locking hole (not shown) of the interior material body 40. In this case, since the interior material body 40 is made of an elastic material having flexibility like the hat body 11, 11, the locking hole can be stretched radially and fitted.

Then, the locking portion of the locking device 21 is inserted into the long mounting hole 56a at one end of the cross strings 56, 56, and then the locking portion of the locking device 21 is fitted into the locking hole 11a, 11a of each of the cap bodies 11, 11. Then, the locking portion of the locking device 21 is inserted into the vertically long locking device insertion hole 22a of the strength member 20, and then pressed until it protrudes from the opening surface of the locking device insertion hole 22a. With the locking portion protruding, the locking portion is rotated with the fingers to a direction approximately perpendicular to the vertical direction of the locking device insertion hole 22a. This fixes the two cross strings 56, 56, the cap body 11, 11, and each of the components of the strength member 20 to the interior material body 40. Note that the disassembly of each component is performed in the reverse order of the assembly order described above.

Next, we will explain how to use this embodiment.

In the folded state of the foldable hat 10 of this embodiment, the cap body 10A for the foldable hat and the covering member 10C are joined to each other by the hook-and-loop fasteners 27, so that the covering member 10C is attached to the entire cap body 10A for the foldable hat and both sides of the interior material 10B as shown in FIG. 9.

As shown in Figure 12, in the folded state in which the front flat plate 22 and the rear flat plate 24 of the strength member 20 are each in a flat state, the user spreads out the interior material main body 40, the cap body 11, the strength member 20, and the reinforcing member 30. In this case, the interior material main body 40 and the cap body 11 are each made of a flexible elastic material such as foamed polyethylene, so they can be spread out very easily.

The strength member 20 expands around the first hinge portion 25 and the second hinge portion 26, and the reinforcing member 30 expands around the third hinge portion 35 and the fourth hinge portion 36. This causes the foldable hat 10 to be in an unfolded state and in a hat state.

In this state, the user puts the foldable hat 10 on his/her head, grasps the chin locking cord 52 of the chin strap member 50, and pulls the chin locking cord 52 downward. Next, the cord stopper 53 is pulled up to hold the chin with the chin locking cord 52, and when the pair of connecting cords 51, 51 are pulled, the front interior material 43 and the rear interior material 44 near the cord locking member 47 are elastically deformed so as to be curved, and this curved portion covers both sides of the head.

At the same time, the front flat plate 22 and the rear flat plate 24 of the strength member 20 rotate in the closing direction via the first hinge portion 25 and the second hinge portion 26 against the elastic force. Similarly, the reinforcing front flat plate 32 and the reinforcing rear flat plate 34 of the reinforcing member 30 rotate in the closing direction via the third hinge portion 35 and the fourth hinge portion 36 against the elastic force.

In this state, when the user of the foldable hat 10 releases the chin locking string 52, the elastic force of the first hinge portion 25, the second hinge portion 26, the third hinge portion 35, and the fourth hinge portion 36 pulls the connecting strings 51, 51 toward the string locking member 47 via the front interior material 43 and the rear interior material 44, and the tension in the connecting strings 51, 51 also pulls the chin locking string 52, causing the chin locking string 52 to be locked to the user's chin, and the unfolded state of the foldable hat 10 is maintained.

Here, when the chin locking string 52 is pulled downward, the strength member 20 and the reinforcing member 30 can be easily elastically deformed via the first hinge portion 25, the second hinge portion 26, the third hinge portion 35, and the fourth hinge portion 36, even if the user of the foldable hat 10 does not apply a large amount of force. In other words, the user of the foldable hat 10 can lock the chin locking string 52 to the chin and maintain the unfolded state with a simple operation without requiring a large amount of force.

When the foldable hat 10 is in the deployed state, the front flat plate 22 and rear flat plate 24 of the strength member 20, the reinforcing member 30, the hat body 11, 11, and the interior material body 40 cover most of the head and neck, so the head can be reliably protected from impacts from falling objects, etc.

In addition, the entire cap body 11 and strength member 20 are covered with the flame-retardant covering member 10C, so that the user's head and neck can be reliably protected from heat and flames even in high-temperature environments such as fires. When the hood portion 12 of the covering member 10C is fastened to the strength member 20, the brace portion 13 of the covering member 10C covers the area from the back of the head to the neck, so that the user's head to the neck can be protected from heat and flames.

When the user of the foldable hat 10 wishes to change from the unfolded state to the folded state, the user of the foldable hat 10 first pulls the string stopper 53 downward while the foldable hat body 10A is still on the head. This releases the chin locking string 52 from its locked state on the user's chin, and the chin locking string 52 is released from the chin.

Even in this case, the user of the foldable hat 10 can easily elastically deform the strength member 20 and the reinforcing member 30 via the first hinge portion 25, the second hinge portion 26, the third hinge portion 35, and the fourth hinge portion 36 without applying a significant amount of force.

Therefore, the user of the foldable hat 10 can easily release the chin fastening string 52 from its engagement with the user's chin with a simple operation without using a large amount of force, and can easily place the foldable hat body 10A in a folded state.

[Embodiment 2 of the Invention]
14 to 27 show a second embodiment of the present invention.

In this second embodiment, the same or corresponding parts as those in the first embodiment are designated by the same reference numerals, and different configurations and functions are described.

The foldable hat body 60A of the foldable hat 60 of the second embodiment differs from the first embodiment mainly in that, except for the hat body main body 11 in the foldable hat body 10A of the foldable hat 10 of the first embodiment, a front side piece 71 and a front connecting piece 72, a rear side piece 73 and a rear connecting piece 74 are provided on the left and right sides of the front flat plate 22 and the rear flat plate 24 of the hat body strength member 70, respectively.

As shown in Figures 14 to 26, the foldable hat 60 includes a foldable hat body 60A, an interior material 60B provided within the foldable hat body 60A, and a covering member 60C attached to the foldable hat body 60A provided with the interior material 60B.

As shown in Figures 14 to 26, the hat body 60A for a foldable hat has a hat body strength member 70, a reinforcing member 30 provided on the hat body strength member 70, and a reinforcing plate 37 superimposed on the upper part of the reinforcing member 30 via a covering member 60C. The hat body 60A for a foldable hat can be changed between a folded state and an unfolded state that can be worn on the head.

The reinforcing member 30, covering member 60C, and reinforcing plate 37 are attached to the front and rear sides of the surface of the helmet body strength member 70 in a stacked manner using four fasteners 21, and the interior material 60B is similarly attached to the back side of the helmet body strength member 70. These fasteners 21 are integrally molded from soft synthetic resin such as polyethylene (PE).

The locking device 21 is locked by fitting one locking member into the other locking member. One locking member is a threaded shaft with a male thread, and a disk portion with a larger diameter than the threaded shaft is integrally provided at the end of the threaded shaft. The other locking member is a threaded shaft with a female thread formed on its inner surface into which the male threaded shaft fits, and a ring portion with a larger diameter than the threaded shaft is integrally provided at the end of the threaded shaft. The hole of the large-diameter ring portion communicates with the female-threaded hole of the threaded shaft. The large-diameter ring portion also has an engagement groove formed along the diameter direction into which a coin can be engaged.

In addition, since the locking device 21 is integrally molded from a synthetic resin such as polyethylene (PE), the male threaded shaft of one locking member is pushed into the female threaded shaft to overcome the threads and screw together, without rotating the male threaded shaft of the other locking member to screw it into the female threaded shaft of the other locking member. In other words, the male threaded shaft against the female threaded shaft prevents one locking member from easily coming off the other locking member.

As shown in Figures 14 to 19 and 21 to 26, the helmet body strength member 70 extends forward and backward from the top of the head and is foldable via the portion facing the top of the head.

As shown in FIG. 23, the hat body strength member 70 is formed symmetrically on the left and right sides by punching out a single hard flat plate. Specifically, the hat body strength member 70 is integrally formed in a plate shape from synthetic resin such as foamed polypropylene, which has high rigidity, high bending strength, and is lightweight, and has a thickness of, for example, about 3.0 mm. The hat body strength member 70 also has the fastener insertion hole 22a and multiple hinge parts (described later) formed during punching.

The helmet body strength member 70 is integrally formed with a front flat plate 22 for covering the forehead, a connecting plate 23 for covering the top of the head, and a rear flat plate 24 for covering the back of the head. In other words, the front flat plate 22 and the rear flat plate 24 are connected via the connecting plate 23.

A first hinge portion 25 is formed between the front flat plate 22 and the connecting plate 23 along the left-right direction, and a second hinge portion 26 is formed between the rear flat plate 24 and the connecting plate 23 along the left-right direction. The connecting plate 23 is formed in a rectangular shape in a plan view. The first hinge portion 25 and the second hinge portion 26 are formed along the left-right direction of the portion facing the top of the head. The first hinge portion 25 and the second hinge portion 26 constitute the top of the head hinge portion in this embodiment.

As shown in FIG. 23, the front flat plate 22 is formed in a generally hexagonal shape when viewed from the front, and fastener insertion holes 22a, 22a are provided at the left and right of the lower part at positions corresponding to the fastening holes 41, 41 (shown in FIG. 21) of the interior material main body 40 and the fastening holes 12a, 12a of the hood portion 12 of the covering member 60C.

Similarly, as shown in FIG. 23, the rear flat plate 24 is formed in a generally hexagonal shape when viewed from the front, and fastener insertion holes 24a, 24a are provided on the left and right sides of the lower part at positions corresponding to the fastening holes 41, 41 (shown in FIG. 21) of the interior material main body 40 and the fastening holes 12a, 12a of the hood portion 12 of the covering member 60C, respectively.

The front flat plate 22 has fastener insertion holes 22a, 22a at the left and right sides of its upper part, which correspond to the fastener insertion holes of the reinforcing member 30, the fastener insertion holes 12a, 12a of the hood portion 12 of the covering member 60C, and the fastener insertion holes of the reinforcing plate 37.

Similarly, the rear flat plate 24 has fastener insertion holes 24a, 24a at the left and right sides of its upper part, which correspond to the fastener insertion holes of the reinforcing member 30, the fastener insertion holes 12a, 12a of the hood portion 12 of the covering member 60C, and the fastener insertion holes of the reinforcing plate 37.

Triangular front side temporal pieces 71, 71 facing the temporal region are formed continuously on the left and right sides of the front flat plate 22. Front side temporal hinge parts 71a, 71a are formed between the left and right sides of the front flat plate 22 and the front side temporal pieces 71, 71, so as to extend diagonally forward. Front side connecting pieces 72, 72, which are approximately rectangular, are formed continuously on the front side temporal pieces 71, 71. Front side connecting hinge parts 72a, 72a are formed between the front side temporal pieces 71, 71 and the front side connecting pieces 72, 72. Locking device insertion holes 72b, 72b are formed in the front side connecting pieces 72, 72.

Similarly, rear side temporal pieces 73, 73 of approximately triangular shape facing the temporal region are formed continuously on the left and right sides of the rear side flat plate 24. Rear side temporal hinge parts 73a, 73a are formed between the left and right sides of the rear side flat plate 24 and the rear side temporal pieces 73, 73 so as to extend diagonally backward. Rear side connecting pieces 74, 74 of approximately rectangular shape are formed continuously on the rear side temporal pieces 73, 73. The rear connecting pieces 74, 74 are formed longer than the front connecting pieces 72, 72 so that they do not interfere with each other when connected to the front connecting pieces 72, 72. Rear connecting hinge parts 74a, 74a are formed between the rear side temporal pieces 73, 73 and the rear connecting pieces 74, 74. The rear connecting pieces 74, 74 are provided with locking device insertion holes 74b, 74b.

The front connecting pieces 72, 72 and the rear connecting pieces 74, 74 are overlapped with each other and connected by inserting the fasteners 21 through the fastener insertion holes 72b, 72b, 74b, 74b, respectively, to give the helmet body strength member 70 a three-dimensional shape. The front side temporal hinge parts 71a, 71a, the front connecting hinge parts 72a, 72a, the rear side temporal hinge parts 73a, 73a, and the rear connecting hinge parts 74a, 74a constitute the temporal hinge part of this embodiment.

The hat body strength member 70 is configured to be foldable in the front-rear direction via the front side temporal hinge parts 71a, 71a, the front side connecting hinge parts 72a, 72a, the rear side temporal hinge parts 73a, 73a, the rear side connecting hinge parts 74a, 74a, the first hinge part 25, and the second hinge part 26.

The helmet body strength member 70 is formed by punching out the four fastener insertion holes 22a in the front flat plate 22, the four fastener insertion holes 24a in the rear flat plate 24, the fastener insertion holes 72b, 72b in the front connecting pieces 72, 72, and the fastener insertion holes 74b, 74b in the rear connecting pieces 74, 74, and at the same time, the first hinge portion 25, the second hinge portion 26, the front side head hinge portions 71a, 71a, the front connecting hinge portions 72a, 72a, the rear side head hinge portions 73a, 73a, and the rear connecting hinge portions 74a, 74a.

The covering member 60C is made of a flame-retardant, foldable material such as tarpaulin (vinyl chloride). In this embodiment, the covering member 60C is formed integrally with the hood portion 12 and the hood portion 13 as shown in FIG. 14. The hood portion 12 is formed in an inverted V-shape in cross section. The hood portion 12 is formed in a three-dimensional shape that fits the shapes of the hat body strength member 70 and the reinforcing member 30 that are formed when the foldable hat 60 is worn on the head in an unfolded state. The hood portion 13 is formed in a substantially trapezoidal shape.

The covering member 60C is fixed in place by inserting the fasteners 21 through the two upper and lower fastener insertion holes 22a, 22a of the front and rear flat plates 22 and 24, the two upper and lower fastener insertion holes 12a, 12a of the hood portion 12 of the covering member 60C, and the fastener insertion holes of the reinforcing plate 37.

The hood section 12 has side pieces formed on the front and rear sides, similar to the hat body strength member 70, at the portion facing the portion connecting the left and right front connecting pieces 72, 72 and the left and right rear connecting pieces 74, 74 of the hat body strength member 70, and these side pieces are overlapped and connected by fasteners 14.

The covering member 60C has both the left and right sides of the rear flat plate 24 cut into the crushing portion 13, and the two cut ends are simultaneously connected by the fasteners 21 when the left and right front connecting pieces 72, 72 and the rear connecting pieces 74, 74 of the hat body strength member 70 are connected, respectively.

In this manner, in this embodiment, the covering member 60C is firmly fixed to the foldable hat 60 by the fastener 21, without being joined by the hook-and-loop fastener 27 as in the first embodiment. When the hood portion 12 of the covering member 60C is fixed to the hat body strength member 70, the brace portion 13 of the covering member 60C spreads out to cover the back of the head and around the neck of the user.

As shown in Figures 18 and 25, the cushioning member 28 is fixed by adhesive to the portion of the hat body strength member 70 facing the top of the head, i.e., the inner surface of the connecting plate 23. This cushioning member 28 is integrally formed from polystyrene foam in a convex shape when viewed from the side, and the corners are chamfered to form a radius. The cushioning member 28 is formed so that its width is approximately the same as the width of the inner surface of the connecting plate 23, its length is slightly shorter than the length of the inner surface of the connecting plate 23, and its height reaches near the top of the head when the foldable hat 60 is worn by the user.

Since the cushioning member 28 is integrally formed with a convex shape in a side view, its strength in the vertical direction is significantly increased. Therefore, even if the cushioning member 28 comes into contact with the top of the head due to the impact of a falling object or the like during an emergency disaster, it can cushion the top of the head and reliably protect the head. In addition, since the corners of the cushioning member 28 are chamfered and formed into a radius, even if the cushioning member comes into contact with the top of the head, it is possible to prevent the top of the head from being damaged.

As in the first embodiment, a reinforcing member 30 is provided on the upper surface of the helmet body strength member 70. Specifically, as shown in FIG. 18, a reinforcing front flat plate 32, a reinforcing connecting plate 33, and a reinforcing rear flat plate 34 are provided on the upper side of the front flat plate 22, the connecting plate 23, and the rear flat plate 24, respectively. The reinforcing member 30 is integrally formed with the reinforcing front flat plate 32 for covering the forehead, the reinforcing connecting plate 33 for covering the top of the head, and the reinforcing rear flat plate 34 for covering the rear of the head.

That is, the reinforcing front flat plate 32 and the reinforcing rear flat plate 34 are connected via a reinforcing connecting plate 33. The reinforcing member 30, like the cap body strength member 70, is formed symmetrically in the left-right direction by punching out a single hard flat plate. Specifically, the reinforcing member 30 is integrally formed into a plate shape from a synthetic resin such as foamed polypropylene that has high rigidity and high bending strength, and has a thickness of, for example, about 3.0 mm.

Since the reinforcing front flat plate 32 and the reinforcing rear flat plate 34 are overlapped on the upper side of the front flat plate 22 and the upper side of the rear flat plate 24, respectively, the reinforcing connecting plate 33 is formed wider by the plate thickness of the front flat plate 22 and the rear flat plate 24. The reinforcing front flat plate 32 is formed in a generally rectangular shape when viewed from the front, and its vertical length is less than half the length of the front flat plate 22. Similarly, the reinforcing rear flat plate 34 is also formed in a generally rectangular shape when viewed from the front, and its vertical length is less than half the length of the rear flat plate 24.

A third hinge portion 35 is formed between the reinforcing front flat plate 32 and the reinforcing connecting plate 33 along the left-right direction, and a fourth hinge portion 36 is formed between the reinforcing rear flat plate 34 and the reinforcing connecting plate 33 along the left-right direction. The reinforcing connecting plate 33 is formed in a rectangular shape in a plan view, similar to the connecting plate 23.

On the left and right sides of the reinforcing front flat plate 32, there are provided fastener insertion holes (not shown) that are elongated in the vertical direction, through which the fasteners 21 are inserted. Similarly, on the left and right sides of the reinforcing rear flat plate 34, there are provided fastener insertion holes (not shown) that are elongated in the vertical direction, through which the fasteners 21 are inserted. These fastener insertion holes are formed in the same positions as the fastener insertion holes of the cap strength member 70, and are in communication with each other, through which the same fasteners 21 are inserted.

The fastener insertion holes in the reinforcing front flat plate 32 and the reinforcing rear flat plate 34 are formed by punching the plate material, similar to the cap body strength member 70. As with the cap body strength member 70, the third hinge portion 35 and the fourth hinge portion 36 are also formed at the same time as punching these fastener insertion holes.

A reinforcing plate 37 made of a colorless, transparent synthetic resin such as polycarbonate is superimposed on the reinforcing front plate 32, with the hood portion 12 in between. The reinforcing plate 37 has a thickness of, for example, about 3.0 mm. The reinforcing plate 37 has a larger radius at the upper corners than at the lower part, and is otherwise formed in substantially the same shape as the reinforcing front plate 32.

Similarly, a reinforcing plate 37 made of a colorless, transparent synthetic resin such as polycarbonate is superimposed on the reinforcing rear plate 34 via the hood portion 12. This reinforcing plate 37 has the same structure as the one superimposed on the reinforcing front plate 32, and is attached in a symmetrical position to the reinforcing plate 37 of the reinforcing front plate 32.

The reinforcing plates 37, 37 provided on the reinforcing front plate 32 and the reinforcing rear plate 34 are curved so that the central portions of the reinforcing plates 37, 37 protrude slightly in the length direction. Therefore, on the back side of the reinforcing plates 37, 37, a plurality of reinforcing ribs 37a that can abut against the reinforcing front plate 32 and the reinforcing rear plate 34 in the length direction are formed at regular intervals.

On the left and right sides of the reinforcing plate 37, there are provided fastener insertion holes through which the fasteners 21 are inserted, at the same positions on the left and right as the fastener insertion holes 22a, 22a provided on the left and right sides of the front flat plate 22 and the reinforcing front flat plate 32. Around these fastener insertion holes, recesses 37b are formed so that the fasteners 21 do not protrude from the upper surface of the reinforcing plate 37 when the fasteners 21 are attached.

In this way, in the hat body 60A for a foldable hat of this embodiment, the hat body strength member 70 is formed in the front-to-back direction of the top of the head by punching out a single hard flat plate, so it is possible to maintain high strength while achieving further weight reduction. And, since the hat body strength member 70 is formed with the front flat plate 22 and the rear flat plate 24 in the front-to-back direction of the top of the head, it is possible to prevent impacts from falling objects, etc.

In addition, in the present embodiment of the hat body 60A for a foldable hat, the hat body strength member 70 is formed by punching out a single hard flat plate, so that it can be easily formed by punching without using a molding device with a metal mold.

Furthermore, in the hat body 60A for a foldable hat of this embodiment, the front side pieces 71, 71 and the rear side pieces 73, 73 that face the sides of the head are continuously formed on the left and right sides of the front flat plate 22 and the rear flat plate 24, respectively, so that the front side pieces 71, 71 and the rear side pieces 73, 73 that protect both sides of the head can be formed simultaneously with the front flat plate 22 and the rear flat plate 24 by punch molding, making it easy to manufacture.

In addition, in the foldable hat body 60A of this embodiment, the front side pieces 71, 71 and the rear side pieces 73, 73 are connected by overlapping the front connecting pieces 72, 72 and the rear connecting pieces 74, 74, respectively, so that the sides of the head can be protected even more firmly.

In addition, the hat body 60A for a foldable hat of this embodiment further includes a flame-resistant covering member 60C that is fixed to the hat body strength member 70 and covers the entire hat body strength member 70, thereby ensuring protection of the head and neck even in high-temperature environments such as fires.

In addition, in the present embodiment of the hat body 60A for a foldable hat, the hat body strength member 70 is constructed by stacking multiple plate materials at least in the portion facing the top of the head, which further prevents impacts from falling objects, etc.

In addition, in the foldable hat body 60A of this embodiment, the shock absorbing member 28 is fixed to the portion of the hat body strength member 70 that faces the top of the head, which further prevents impacts from falling objects, etc.

Next, we will explain the interior material 60B used as the interior material for hats in this embodiment.

As shown in Figures 15 to 18, the interior material 60B is attached to the inside of the hat body 60A for the foldable hat, and holds the head when the user wears the foldable hat 60. The interior material 60B includes an interior material main body 40, a chin strap member 50 connected to the interior material main body 40, and a back of the head holding member 54 through which the chin strap member 50 is inserted.

In addition, the interior material 10B of the first embodiment is provided with cross strings 56 as shown in Figs. 7 and 8, but the interior material 60B of the present embodiment is not provided with cross strings as shown in Fig. 21.

The interior material body 40 is formed integrally by punching from a plate-like flexible elastic material such as colored, opaque, expanded polyethylene. Therefore, the interior material body 40 can be changed between a folded state and an unfolded state. The interior material body 40 has a thickness of, for example, about 5.0 mm.

The interior material body 40 is made of a flexible elastic material such as polyethylene foam, and therefore has a lighter specific gravity than synthetic resins with a certain degree of rigidity such as headbands that are provided as part of general interior materials. This allows the interior material body 40 to be made lighter in weight in this embodiment.

As shown in FIG. 20, the interior material body 40 is integrally formed to cover the front and back of the head, and is formed with a shape that is symmetrical in left and right planes. As shown in FIG. 21, the interior material body 40 is folded from approximately the middle of its length in the front-to-back direction, excluding the eaves portion described below, and both left and right ends of the folded material are fixed by fasteners 42. Therefore, as shown in FIG. 27, the interior material body 40 is formed into a front interior material 43 for covering the front of the head and a rear interior material 44 for covering the back of the head. This allows the interior material body 40 to be folded in the front-to-back direction.

As shown in Figs. 14 to 20, a visor portion 45 is integrally formed in front of the front interior material 43 and protrudes forward. When the interior material 60B is attached to the hat body 60A for a foldable hat, this visor portion 45 is attached so as to protrude forward from the hat body strength member 70. As shown in Fig. 20, an opening 43a that is long in the left-right direction is formed in approximately the center of the front interior material 43. An approximately trapezoidal opening 43c is formed in approximately the center of the rear interior material 44.

As shown in FIG. 20, vertex cutouts 48, 48 that are long in the front-to-rear direction are formed on the left and right at the position facing the vertex between the front interior material 43 and the rear interior material 44. These vertex cutouts 48, 48 are formed symmetrically in a roughly arc shape. The interior material body 40 between these vertex cutouts 48, 48 is flexible and can bend downward.

These openings 43a, 43c and the left and right vertex cutouts 48, 48 all function as air vents. In addition, the space between the left and right vertex cutouts 48, 48 faces the cushioning material 28 when the interior material 60B is attached to the foldable hat body 60A.

The buffer plate 46 is formed in a substantially rectangular shape and abuts against the forehead, and is provided at the inner center of the front interior material 43, closer to the top of the head than the visor portion 45. Specifically, one side of a hook-and-loop fastener (not shown) is adhered to the inner center of the front interior material 43, and the other side of the hook-and-loop fastener (not shown) is adhered to the middle of the length of the buffer plate 46, and the buffer plate 46 is detachably attached to the front interior material 43 by joining these hook-and-loop fasteners. When the interior material 60B is attached to the hat body 60A for the foldable hat and the user puts on the foldable hat 60, the buffer plate 46 is attached to the inner surface of the front interior material 43 in a position facing the forehead of the user.

As shown in Figures 17 and 18, the front interior material 43 is provided with cord locking members 47 near the left and right sides of the buffer plate 46, through which the connecting cord 51 is inserted and locked. Similarly, the rear interior material 44 is provided with cord locking members 47 near the left and right sides of the rear end, through which the connecting cord 51 is inserted and locked.

Below, the configurations and functions of the chin strap member 50 connected to the interior material main body 40, the chin locking strap 52, the occipital region retaining member 54 through which the chin strap member 50 is inserted, etc. are the same as those in the first embodiment, so their explanation will be omitted.

The two fasteners 21 attached to the front interior material 43 and the rear interior material 44 are inserted through the fastener insertion holes 22a in the front flat plate 22 and the fastener insertion holes 24a in the rear flat plate 24 of the hat body strength member 70. This causes the interior material body 40 to be attached to the hat body strength member 70. In other words, the interior material 60B is attached to the hat body 60A for a foldable hat.

In the interior material 60B of this embodiment, the interior material main body 40 is formed of a plate-like flexible elastic material, and when the interior material 60B is attached to the hat body 60A for a foldable hat, the area between the left and right crown notches 48, 48 is positioned facing the buffer member 28, which improves the fit when the foldable hat 60 is worn, and, in combination with the buffering effect of the buffer member 28, further prevents impacts from falling objects, etc. Other effects are the same as in embodiment 1, so a description thereof will be omitted.

Next, we will explain the operation of the foldable hat 60 of this embodiment.

To attach the reinforcing member 30 and the reinforcing plate 37 to the helmet strength member 70, one of the fastening members of the fastening device 21 is fitted into the fastening device fastening holes 22a, 24a at the top of the front flat plate 22 and the rear flat plate 24 of the helmet strength member 70.

Then, this locking member is inserted through the locking device insertion holes 22a, 22a, 24a, 24a in the upper part of the cap body strength member 70, and further through the locking device insertion holes (not shown) of the reinforcing member 30 and the reinforcing plate 37, and then one locking member is pushed into the other locking member. This fixes the reinforcing member 30 and the reinforcing plate 37 to the cap body strength member 70.

To assemble the hat body strength member 70 to the interior material body 40, the other locking member of the locking device 21 is fitted into the locking hole 41 of the interior material body 40.

Then, one of the fastening members of the fastening device 21 is inserted into the fastening device insertion holes 22a, 22a, 24a, 24a at the bottom of the hat body strength member 70, and then the one fastening member is pushed into the other fastening member through the fastening device insertion holes 22a, 22a, 24a, 24a. This fixes the interior material main body 40 to the hat body strength member 70.

Next, we will explain how to use this embodiment.

In the folded state of the foldable hat 60 of this embodiment, the foldable hat body 60A and the covering member 60C are fixed by the fastener 21, so that the covering member 60C is attached to the entire foldable hat body 60A and both sides of the interior material 60B as shown in FIG. 22.

As shown in Figure 26, in the folded state in which the front flat plate 22 and the rear flat plate 24 of the helmet body strength member 70 are each in a flat state, the user spreads out the interior material body 40, the helmet body strength member 70, and the reinforcing member 30. In this case, the interior material body 40 can be spread out very easily because it is made of a flexible elastic material such as foamed polyethylene.

The hat body strength member 70 expands around the first hinge portion 25, the second hinge portion 26, the front connecting hinge portion 72a, and the rear connecting hinge portion 74a, while the reinforcing member 30 expands around the third hinge portion 35 and the fourth hinge portion 36. This causes the foldable hat 60 to be in an unfolded state, and to be in a hat state.

In this state, the user puts the foldable hat 60 on his/her head, grasps the chin locking cord 52 of the chin strap member 50, and pulls the chin locking cord 52 downward. Next, the cord stopper 53 is pulled up to hold the chin with the chin locking cord 52, and when the pair of connecting cords 51, 51 are pulled, the front interior material 43 and the rear interior material 44 near the cord locking member 47 are elastically deformed so as to be curved, and this curved portion covers both sides of the head.

At the same time, the front flat plate 22 and the rear flat plate 24, the front side head piece 71 and the rear side head piece 73 of the hat body strength member 70 rotate in the closing direction via the first hinge portion 25 and the second hinge portion 26, the front connecting hinge portion 72a and the rear connecting hinge portion 74a against the elastic force. Similarly, the reinforcing front flat plate 32 and the reinforcing rear flat plate 34 of the reinforcing member 30 also rotate in the closing direction via the third hinge portion 35 and the fourth hinge portion 36 against the elastic force.

In this state, when the user of the foldable hat 10 releases the chin locking string 52, the elastic forces of the first hinge portion 25, the second hinge portion 26, the front connecting hinge portion 72a, the rear connecting hinge portion 74a, the third hinge portion 35, and the fourth hinge portion 36 pull the connecting strings 51, 51 toward the string locking member 47 via the front interior material 43 and the rear interior material 44, and the tension in the connecting strings 51, 51 also pulls the chin locking string 52, causing it to be locked to the user's chin, and the unfolded state of the foldable hat 10 is maintained.

Here, when the chin locking string 52 is pulled downward, even if the user of the foldable hat 60 does not apply a large amount of force, the hat body strength member 70 and the reinforcing member 30 can be easily elastically deformed via the first hinge portion 25, the second hinge portion 26, the front connecting hinge portion 72a, the rear connecting hinge portion 74a, the third hinge portion 35, and the fourth hinge portion 36. In other words, the user of the foldable hat 10 can lock the chin locking string 52 to the chin and maintain the unfolded state with a simple operation without using a large amount of force.

When the foldable hat 60 is in the deployed state, the front flat plate 22 and rear flat plate 24 of the hat body strength member 70, the reinforcing member 30, and the interior material body 40 cover most of the head and neck, so the head can be reliably protected from impacts from falling objects, etc.

In addition, because the entire helmet body strength member 70 is covered with the flame-retardant covering member 60C, the user's head and neck can be reliably protected from heat and flames even in high-temperature environments such as fires. When the hood portion 12 of the covering member 60C is fixed to the helmet body strength member 70, the brace portion 13 of the covering member 60C covers the area from the back of the head to the neck, so the user's head to neck can be protected from heat and flames.

When the user wishes to change the foldable hat 60 from the unfolded state to the folded state, the user of the foldable hat 60 first pulls the string stopper 53 downward while the foldable hat 60 is still on the head. This releases the chin locking string 52 from its locked state on the user's chin, and the chin locking string 52 is released from the chin.

Even in this case, the user of the foldable hat 60 can easily elastically deform the hat body strength member 70 and the reinforcing member 30 via the first hinge portion 25, the second hinge portion 26, the front side temporal hinge portion 71a, the front side connecting hinge portion 72a, the rear side temporal hinge portion 73a, the rear side connecting hinge portion 74a, the third hinge portion 35, and the fourth hinge portion 36, without applying a significant amount of force.

Therefore, the user of the foldable hat 60 can release the chin fastening string 52 from its engagement with the user's chin with a simple operation without using a large amount of force, and the foldable hat 60 can be easily folded.
