Description

The present invention relates to a helmet, and more particularly to a helmet capable of varying the cushioning state in the cap.

With the recent health consciousness, the number of people who enjoy walking and running is increasing rapidly, and hiking and mountain climbing are also gaining popularity. On the other hand, there are many people who want to wear light clothing such as walking to climb a mountain, which poses a safety problem, and it is desirable to wear a helmet that protects at least the head. However, since ordinary helmets are bulky and inconvenient to carry, the burden on climbers is heavy. In addition, the cycling population is increasing, and it is desirable to wear a helmet as well, but it is still inconvenient to carry a helmet. In order to eliminate such inconvenience, for example, a helmet as shown in Patent Document 1 has been proposed. That is, this helmet can be folded and stored by welding and connecting a plurality of vinyl chloride sheet materials that become hemispherical when connected in the circumferential direction to form a cap, and by blowing air into the helmet. It functions as.

On the other hand, the conventional helmet has a problem in the fit to the user's head when worn. Therefore, for example, a protective helmet for sports activities shown in Patent Document 2 has been proposed. In this protective helmet, the pocket on the back of the helmet is initially inflated, and the overpressured air in the pocket can be removed by simply putting the protective helmet in that state to a comfortable position with respect to the head. By being discharged by the adjusting means, it is possible to eliminate the discomfort of the user by closely deforming according to the outer shape of the head of the protective helmet user.

1. 1. First Embodiment [Helmet configuration]
Hereinafter, the helmet according to the present invention will be described in detail based on a preferred embodiment. FIG. 1 is a sectional view showing a first embodiment of the helmet according to the present invention, FIG. 2 is a perspective view of the helmet shown in FIG. 1, and FIG. 3 is a bottom view of the helmet shown in FIG. The illustrated helmet 1 is generally a recessed cap body (also referred to as a "crown") 10 which is placed on the user's head and has a collar portion (also referred to as a "visor") 15 at the front portion thereof. A first cushion member 11 arranged on the inner crown surface, a second cushion member 12 arranged on the inner side surface of the cap body 10, and a top bag-shaped member 13 containing the first cushion member 11 , A side bag-shaped member 14 having a second cushion member 12 inside is provided.

The cap body 10 is formed of an appropriate material such as cotton, linen, polyester, polyurethane, acrylic, synthetic leather, etc., which has been given a desired color, pattern, etc., and after cutting these materials according to the shape of the hat, etc. , Sewn (or welded), and a collar (also referred to as "visor") 15 is attached according to the specifications, and a top button 16 (not necessarily) is attached to the top. As a result, a desired shape, for example, a baseball cap, an Apollo cap, an Eaton cap, a marine cap, a mesh cap, or the like is formed. As will be described later, the fit to the head can be adjusted as appropriate, but it is also possible to provide a predetermined size (S, M, L = small, medium, large, etc.) on the cap body. In addition, an adjuster 17 (FIG. 1 is an example of a hook-and-loop fastener and FIG. 2 is an example of a string) that adjusts the hat size according to the specifications and design is attached to the rear part of the cap body 10, and sweat is removed from the inner lower edge. It is also possible to attach it.

The upper bag-shaped member 13 and the side bag-shaped member 14 are bag-shaped members having airtightness, and have a sealed structure so as to be able to keep the air contained therein, for example, a material such as vinyl. Is formed using. In the present embodiment, the illustrated top bag-shaped member 13 and the side bag-shaped member 14 are formed so as to communicate with each other at at least one place, but they may be formed independently without communicating with each other. .. Adjacent portions of the upper bag-shaped member 13 and the side bag-shaped member 14 are welded to each other, and a ventilation valve 19 is attached to the air inlet / outlet portion of the upper bag-shaped member 13. Then, through the ventilation valve 19, air can be blown into both the upper bag-shaped member 13 and the side bag-shaped member 14, and conversely, air can be evacuated. When the upper surface bag-shaped member 13 and the side bag-shaped member 14 are not communicated with each other, the ventilation valve 19 is attached to each of the upper surface bag-shaped member 13 and the side bag-shaped member 14. A first cushion member 11 is installed inside the upper bag-shaped member 13, and a second cushion member 12 is installed inside the side bag-shaped member 14.

The first cushion member 11 and the second cushion member 12 are members having cushioning properties such as sponge, foamed plastic, and EVA (ethylene-vinyl acetate copolymer resin), and are members for cushioning impact. is there. The first cushion member 11 is formed in a substantially circular shape and is housed in a top bag-shaped member 13 arranged on the back surface of the top of the cap body 10. Further, the second cushion member 12 is formed in a substantially rectangular shape and is housed in a side bag-shaped member 14 arranged on the inner side surface of the cap body 10. The second cushion member 12 may be formed so as to go around the inner side surface of the cap body 12 with one member, or may be divided into a plurality of members and arranged. The larger the thickness of the first cushion member 11 and the second cushion member 12, the higher the impact resistance. However, as will be described later, the inner diameter of the helmet 1 becomes smaller at normal pressure (= atmospheric pressure state). Therefore, it is necessary to select the material and thickness appropriately according to the application, gender, age, etc. of the user.

As shown in FIGS. 4A to 4B, the ventilation valve 19 is a member for blowing or discharging air into the upper bag-shaped member 13 and the side bag-shaped member 14. The ventilation valve 19 is formed of, for example, a synthetic resin material such as vinyl, and is welded to a predetermined position (near the back of the head in the present embodiment) of the upper bag-shaped member 13 as shown in FIG. 4A. A hemispherical base 20a, a cylinder 20b erected on the base 20a, and a plug 20d connected to the cylinder 20b by a band-shaped connecting member 20c and inserted into the opening 20e of the cylinder 20b. It is configured to prepare. The base portion of the base 20a is formed in a disk shape and is attached to the upper bag-shaped member 13. Then, the plug body 20d is inserted into the opening 20e (see FIG. 4B) while bending the connecting member 20c, thereby blocking the flow of air from the opening 20e. When air is discharged from the inside of the upper surface bag-shaped member 13 and the side bag-shaped member 14 formed in this way through the ventilation valve 19 to reduce the pressure, the first one built in the upper surface bag-shaped member 13. The second cushion member 12 incorporated in the cushion member 11 and the side bag-shaped member 14 is compressed into a thin plate shape. In this state, when the ventilation valve 19 is opened to allow air to flow inside the upper bag-shaped member 13 and the side bag-shaped member 14 and return to normal pressure, the first cushion member 11 and the second cushion member 12 are released. It will expand and return to its original state. The internal volume (capacity) of the upper bag-shaped member 13 and the side bag-shaped member 14 is larger than the volume when the first cushion member 11 and the second cushion member 12 return to their original states. The cushioning property and the fit property can be adjusted by adjusting the amount of air blown into the excess volume portion.

Further, as shown in FIG. 3, a plurality of ventilation holes (also referred to as “holes”) 18 and 18 (also referred to as “holes”) 18 and 18 (this implementation) are provided in the crown surface of the cap body 10, the first cushion member 11 and the upper bag-shaped member 13. In the form, four) are formed so that the stuffiness generated in the cap body 10 can escape to the outside. Needless to say, it is of course possible to provide the same ventilation holes 18 in the second cushion member 12 and the side bag-shaped member 14. In order to provide the vent 18 in the first cushion member 11 and the upper surface bag-shaped member 13, the upper surface bag-shaped member 13 in a predetermined portion is compressed from above and below with the first cushion member 11 sandwiched, and the state thereof. The predetermined area is welded as it is. Then, by drilling the vent 18 on the welded surface, the vent 18 can be provided while ensuring the airtightness of the upper bag-shaped member 13.

[How to use Helmet 1]
Next, the method of using the helmet 1 described above will be described. FIG. 5 is a cross-sectional view showing a state in which a helmet is worn. Here, in FIG. 5, the head is shown without hair in order to make it easy to understand the close contact state between the head surface and the inner surface of the helmet. There are three ways to use the helmet 1 when the user 2 wears it on his head.

(1) The air inside the bag-shaped members 13 and 14 is evacuated to a negative pressure state, and the first and second cushion members 11 and 12 are compressed to function as a normal hat.
(2) The inside of the bag-shaped members 13 and 14 is set to atmospheric pressure, and the first and second cushion members 11 and 12 are made to function as a helmet due to the cushioning property.
(3) Further air is blown into the bag-shaped members 13 and 14, and in addition to the elastic force of the first and second cushion members 11 and 12, the balloon effect of the bag-shaped members 13 and 14 is added to the impact resistance of the helmet 1. It enhances the sex and gives the fit.

The three usages (1) to (3) above will be specifically described below. First, when using as a normal hat (in the case of (1)), first, the ventilation valve 19 is opened, and the two bag-shaped members 13, 14 are used from the ventilation valve 19 by using a manual pump or the like. The air inside is discharged, and the inside of both bag-shaped members is put into a negative pressure state. Then, when the air in the bag-shaped members 13 and 14 is sufficiently exhausted, the ventilation valve 19 is closed to seal the inside of the bag-shaped members 13 and 14. At this time, the first and second cushion members 11 and 12, respectively, are compressed to reduce the thickness, and can be used in almost the same manner as a normal baseball cap. Even in this case, since the first and second cushion members 11 and 12 are arranged in a compressed state, they have more impact resistance than a normal baseball cap or the like. Further, since the inner diameter of the side portion of the cap body 10 is increased by the compression of the first and second cushion members 11 and 12, the inner diameter of the helmet 1 can be adjusted to the head size of the user 2 by adjusting the amount of air to be extracted. Can be fitted. It can also be fitted to the head by the adjuster 17.

Next, a case of functioning as a helmet (case of (2)) will be described. When the ventilation valve 19 is opened in a state where the first and second cushion members 11 and 12 are compressed to reduce the thickness (in the case of (1)), air flows into the bag-shaped members 13 and 14 and the atmospheric pressure is increased. Then, the first and second cushion members 11 and 12 instantly return to their original states. As a result, the first and second cushion members 11 and 12 exert the elastic force originally provided against the impact from the outside. That is, it can be used as a helmet immediately by simply opening the ventilation valve 19, and since it does not require the labor and time to blow air, it is possible to respond quickly in an emergency.

A case where the impact resistance is further enhanced (in the case of (3)) will be described. When the inside of the bag-shaped members 13 and 14 is in the atmospheric pressure state and the first and second cushion members 11 and 12 are returned to the original state (in the case of (2)), more air is blown from the ventilation valve 19. Since the volumes of the two bag-shaped members 13 and 14 are formed to be larger than the volumes of the first and second cushion members 11 and 12 at normal pressure, the two bag-shaped members 13 and 14 are further inflated like a balloon. As a result, the impact resistance of the helmet 1 is increased by further applying the elastic force due to the tension of the bag-shaped members 13 and 14 to the elastic force of the first and second cushion members 11 and 12 in the case of the above (1). It will be even higher. Further, since the inner diameter of the helmet 1 can be reduced by blowing air into the bag-shaped members 13 and 14, even if the user feels that the size of the helmet 1 is large, the fit is improved by blowing air. be able to.

As described above, according to the helmet shown in the first embodiment, there is an effect that a normal hat can be instantly converted into a helmet having impact resistance and used. Then, if the air inside the bag-shaped members 13 and 14 is released, it can be folded into a small size, which has the effect of being convenient for carrying and storing. Further, there is an effect that the fit to the head of the user can be appropriately adjusted by adjusting the degree of expansion of the first and second cushion members 11 and 12.

2. 2. Second embodiment [helmet configuration]

Is. The illustrated helmet 3 is a so-called half-cap type made by molding a hard resin material (or processing a metal material), but other types such as a jet type and a flip-up type. May be good.

As a general rule, the helmet 3 allows the cap body 30 formed by the four substantially crescent-shaped first to fourth movable pieces 31a to 31d and the first to fourth movable pieces 31a to 31d to be overlapped with each other. Further, on the inner ceiling surface and side surface so as to cover the pair of shaft portions 32, 32 that are pivotally supported so as to form one hemisphere when these are deployed, and the first to fourth movable pieces 31a to 31d. The upper surface bag-shaped member 33 and the side bag-shaped member 34 arranged, the third and fourth cushion members 35 and 36 housed in the two bag-shaped members 33 and 34, and the pair of shaft portions 32, It is configured to include an agony string 37 that is pulled down from the vicinity of 32 and attached to the jaw of the user 2.

The first to fourth movable pieces 31a to 31d are all made of the same material, for example, ABS (acrylic nitrol butadiene styrene), PC (polycarbonate), PE (polyethylene), FRP (fiberglass reinforcement plastic). ) Etc. are molded to form a substantially crescent shape that looks like a hemisphere divided into four. The number of movable pieces 31 constituting the cap body 30 is not limited to four, and may be five or more. A collar portion 38 is provided on the first movable piece 31a. Further, the movable radii of the first to fourth movable pieces 31a to 31d are slightly different from each other, so that the four pieces can be overlapped into one. This structure makes it possible to reduce the storage space when carrying. The same materials as those of the first to fourth movable pieces 31a to 31d can be used for the shaft portions 32 and 32 that pivotally support the first to fourth movable pieces 31a to 31d with a common shaft. It is also possible to provide ventilation holes (not shown) as shown in the first embodiment in the first to fourth movable pieces 31a to 31d.

The top bag-shaped member 33 and the side bag-shaped member 34 have the same structure as the top bag-shaped member 13 and the side bag-shaped member 14 shown in the first embodiment, and the positions for arranging them are also shown in FIGS. 8 and 9. As shown, they are arranged on the inner surface of the ceiling and the inner surface of the side in almost the same manner. In the present embodiment, the top bag-shaped member 33 and the side bag-shaped member 34 are not communicated with each other, and ventilation valves 19 and 19 are provided for each of the top bag-shaped member 33 and the side bag-shaped member 34 to individually inject air. It has a structure that allows entry and exit. The portions where the upper surface bag-shaped member 33 and the side bag-shaped member 34 are in contact with each other are welded so as to be connected so as to be united as a whole. Further, only a part of the upper surface bag-shaped member 33 and the side bag-shaped member 34 is attached to the cap body 30, and the other parts are not connected to the cap body 30. As a result, even if the first to fourth movable pieces 31a to 31d are folded or unfolded, the first to fourth movable pieces 31a to 31d do not interfere with the operation, as shown in FIG. It is in a state of being housed inside the first to fourth movable pieces 31a to 31d folded in.

The third and fourth cushion members 35 and 36 are made of the same material as the first and second cushion members 11 and 12 shown in the first embodiment, and have an upper surface similar to that of the first embodiment. It is charged in the bag-shaped member 33 and the side bag-shaped member 34. It is also possible to provide a hammock, a head hand, sweat-proof leather, and the like inside the upper bag-shaped member 33 and the side bag-shaped member 34 in the same manner as a normal helmet.

[How to use Helmet 3]
Next, a method of using the helmet 3 according to the second embodiment described above will be described with reference to FIGS. 6 and 7 to 10. First, the user unfolds the first to fourth movable pieces 31a to 31d of the helmet 3 in the folded state as shown in FIG. That is, the first and fourth movable pieces 31a and 31d are opened by pushing them in the direction of the arrows BB in FIG. 7, and the state is as shown in FIG. As a result, the inner upper bag-shaped member 33, the side bag-shaped member 34, and the third and fourth cushion members 35 and 36 are in a state of imitating the inner peripheral surface of the cap body 30.

Next, when the ventilation valves 19 and 19 are opened and air is blown into the upper bag-shaped member 33 and the side bag-shaped member 34 to bring the air pressure into an atmospheric pressure state, the first and second cushion members 11 and 12 are instantly in their original state. Return to. As a result, the cushion members 35 and 36 can ensure the impact resistance against an external impact.

Further, if the ventilation valve 19 of the upper surface bag-shaped member 33 and the ventilation valve 19 of the side bag-shaped member 34 are opened and air is blown into the upper surface bag-shaped member 33 and the side bag-shaped member 34, the upper surface bag-shaped member 33 is further opened. And the side bag-shaped member 34 can be further inflated. In addition to the elastic forces of the third and fourth cushion members 35 and 36 by inflating the upper surface bag-shaped member 33 and the side bag-shaped member 34 in this way, the upper surface bag-shaped member 33 and the side bag-shaped member 34 The impact resistance of the helmet 3 is further improved by applying the elastic force due to the tension of the helmet 3. In this case, since the inner diameter of the helmet 3 becomes smaller, if the amount of air to be injected is appropriately adjusted, it can be used to improve the fit when the inner diameter of the helmet 3 is felt to be too large.

On the other hand, by exhausting the air in the upper bag-shaped member 33 and the side bag-shaped member 34 using a manual pump or the like to reduce the pressure inside, the third and fourth cushion members 35 and 36 are compressed. The volumes of the third and fourth cushion members 35 and 36 can be reduced, and this makes it possible to bring the helmet 3 into a compact state that is convenient for storing and carrying in combination with the folding of the cap body 30.
