Description

  The present invention relates to a helmet, and more particularly to a helmet that is suitable for wearing when attending a bicycle.

Conventionally, a helmet interior device for deodorizing and dehumidifying sweat odor when wearing a helmet is known (Patent Document 1), and in order to cool the head under hot weather such as in summer, it is between the outer material and the lining material. A head cooling pad having a three-layer structure in which a non-woven fabric made of polymer fibers having water absorption and water retention properties is enclosed is known (Patent Document 2) and continues from the front to the back of the head through the top of the head. A baseball helmet in which a running wind is guided between the inner side of the helmet and the head to improve the cooling effect by forming a ventilation path composed of a groove is known (Patent Document 3).
JP-A-8-302515 Utility Model Registration No. 3075471 Japanese Patent No. 2978755

  In the helmet interior device described in Patent Document 1 (FIG. 4), a plurality of bag-shaped material warehouses are arranged side by side with two horizontally long belts, and a deodorizing material is formed in each material warehouse. As described above, Bincho charcoal powder is incorporated, and this is inserted into the upper side of the buffer body through the gap of the buffer body mounted on the inner side of the helmet, and is arranged along the inner surface of the helmet. Therefore, deodorization and dehumidification of sweat odor when wearing a helmet can be performed. However, when riding a bicycle wearing a helmet, it is not possible to expect a cooling effect that cools the head by introducing running wind, but also cannot expect an impact absorbing effect.

  On the other hand, the head cooling pad described in Patent Document 2 (FIG. 2) has a three-layer structure in which a non-woven fabric made of a polymer fiber having water absorption and water retention is enclosed between the outer material and the lining material. It is attached to the inner surface of the cap so that the outer side of the forehead hits the forehead. Therefore, the head can be cooled when the hat is worn. However, sweat odor deodorization and dehumidification cannot be expected. In addition, when riding a bicycle wearing a hat, it is not possible to expect a cooling effect that cools the head by introducing a running wind, and also cannot expect an impact absorbing effect. This is the same even when the gel described in the [Prior Art] column of Patent Document 2 is used as a coolant instead of the nonwoven fabric.

  On the other hand, the baseball helmet described in Patent Document 3 (FIG. 3) has a ventilation formed by a groove continuous from the front to the back of the hemispherical liner provided inside the shell main body through the top of the head. A road is formed. Therefore, the cooling effect can be enhanced by cooling the head by guiding the running wind generated during stealing, defensive or running during training between the inside of the helmet and the head. Moreover, since the groove | channel is not formed in the side head of a liner, the fall of impact resistance and a shock absorption effect can be suppressed. However, sweat odor deodorization and dehumidification cannot be expected. Moreover, it does not have a function to improve fit when wearing a helmet.

  Therefore, the purpose of the present invention is to improve the cooling effect of the head by flowing the running wind between the inside of the helmet and the head, to deodorize and dehumidify sweat odor, and to enhance the impact absorption effect, It is to provide a helmet capable of maintaining stable wearing by improving the fit property when worn.

  When the helmet of the present invention is worn and the bicycle is run, a cooling effect is obtained in which the running wind flows down the ventilation path and cools the wearer's frontal region, the boundary between the top and the temporal region, and the back of the head. It is done.

  Moreover, since the inner peripheral end where the bag body in the 2nd buffer body overlaps is obstruct | occluded with respect to the ventilation path, it can avoid that the driving | running | working wind which flows down a ventilation path touches the inner peripheral edge where a bag body overlaps. Therefore, since the running wind smoothly flows down the air passage without being disturbed, the air permeability is improved and the cooling effect can be further enhanced.

  Furthermore, since the first buffer body is constituted by the bag body in which the gel is enclosed, the head portion can be protected by the shock absorbing action of the gel, and the gel is easily deformed along the top portion, so that the helmet is worn. The fit of time improves. In addition, since gel has a large heat capacity and is difficult to transfer heat, keep it in a cool place away from direct sunlight and high temperatures. The cooler first buffer is fitted to the top of the head to give a cool feeling, and even if the resin shell is exposed to direct sunlight, the effect of the gel on the top of the head can be alleviated.

  In addition, since the pair of left and right second buffer bodies are constituted by a breathable bag body in which charcoal powder is housed, deodorization by adsorption of sweat odor and dehumidification by adsorption of moisture of sweat are performed by the charcoal powder, and the helmet In addition to refreshing the wearer's mood, the negative ion effect that reduces the positive ions in the air caused by charcoal powder reduces the irritation to the scalp and protects the scalp, while also calming fatigue and stress. It can be demonstrated. In addition, the charcoal powder that has been deodorized and dehumidified can be used repeatedly because the deodorizing and dehumidifying functions are restored by natural drying.

In the present invention, the bag body constituting the pair of left and right second buffer bodies forms a plurality of bag portions between the sheet and the nonwoven fabric, and each bag portion is long in the circumferential direction of the helmet, Moreover, it is preferable that short ridges are formed in the width direction, the ridges are substantially parallel to each other, and an air flow path is formed between the ridges.
According to this aspect, the running wind flows down the air flow path between the protrusions, so that the air permeability is improved and the cooling effect can be further enhanced.
Moreover, each bag part which comprised charcoal powder internally is long in the circumferential direction of the said helmet, and forms the short ridge in the width direction. Therefore, it is possible to prevent the charcoal powder from being biased downward in the bag portion, so that the fit of the second buffer body to the head is further improved.

In the present invention, it is preferable that the second buffer body is composed of a plurality of bag bodies, and each of the bag bodies is formed in a sector shape or a trapezoidal shape and arranged along the circumferential direction.
According to this aspect, by forming each bag body in a fan shape or a trapezoidal shape, the bag body can be disposed along the side of the liner.
In particular, for example, as shown in FIG. 6, the bag body can be manufactured without waste of material by forming the bag body in a trapezoidal shape.

  The helmet of the present invention is preferably configured by enclosing a soft gel in which the first buffer body has a penetration of 20 to 200 in a bag. According to this, the fit property when wearing a helmet is further improved, and this good fit property can be stably maintained. Therefore, since the movement of the helmet due to wind pressure, vibration, or the like can be suppressed, it is possible to avoid the field of view from being blocked by the buttocks during bicycle traveling and contribute to the execution of safe traveling. If the gel penetration is less than 20, the flexibility becomes excessive and the secondary shock absorbing action is reduced. If the gel penetration exceeds 200, the flexibility is lost and the fit property is reduced. As a result, the helmet cannot be held stably, and the helmet moves due to wind pressure and vibration. Therefore, it is recommended to use a soft gel having a penetration of 20 to 200.

  In the helmet according to the present invention, the second buffer body is constituted by charcoal powder made of discarded wood and a bag body in which the charcoal powder is housed. Waste wood generally contains a large amount of soft wood such as cedar and pine, so that it has a higher impact absorbing effect than charcoal powder made of hard wood such as firewood. Therefore, the temporal region can be protected by the high impact absorbing action of the charcoal powder made from discarded wood.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Example 1:
1 to 3 show a first embodiment.
1, 2 </ b> A, and 2 </ b> B, the school helmet H includes a shell 1, a liner 2, a first buffer 3, and a pair of left and right second buffers 4.

  The shell 1 is made of resin, and a hemispherical shell-shaped main body 10 that covers the top of the helmet H wearer's head and the temporal region, and a flange 11 that protrudes forward from the main body 10 are integrally formed. Yes.

  The liner 2 is a hemispherical shell-shaped impact absorbing member made of, for example, styrene foam, and is provided inside the main body 10.

  The first shock absorber 3 protects the top of the head, improves the fit when wearing the helmet H, and suppresses the movement of the helmet H due to wind pressure or vibration during cycling, and is made of a resin film. A disk-shaped convex portion 30a, a surface material 30 having an extending portion 30b extending to the outer peripheral area of the disk-shaped convex portion 30a, a flat made of a nonwoven fabric made of a polymer fiber, and its outer peripheral edge portion in the surface material 30 A bag body 32 comprising a lining 31 welded to the outer peripheral edge of the disk-shaped convex portion 30a, and a disk-shaped silicone gel 33 enclosed in the bag body 32 are provided. Are arranged inside the liner 2 in contact with the inner surface of the top of the head. Further, the penetration of the disc-shaped silicone gel 33 is set in the range of 20 to 200.

  The pair of left and right second buffer bodies 4 protects the temporal region, deodorizes by sweat odor adsorption and dehumidifies by sweat moisture adsorption, refreshing the feeling of the helmet H wearer, and further to the scalp It is intended to relieve irritation, protect the scalp, and exert the effect of calming fatigue and stress. As shown in FIG. 1, FIG. 2A, FIG. 2B and FIG. It is comprised by the bag body 41 which has the air permeability which was quilted. The air-permeable bag body 41 includes a flat outer surface 42 made of non-woven fabric made of polymer fibers and having air permeability, and a lining 44 made of a resin film and formed with a large number of convex portions 43. The gap 45 between 43 is quilted to the surface material 42 by welding, and charcoal made of waste wood such as cedar and pine is formed between a large number of convex portions 43 surrounded by the quilting, the surface material 42 and the lining material 44. Charcoal powder 40 produced by pulverizing is incorporated. The pair of second shock absorbers 4 having such a configuration is arranged inside the liner 2 in a state where a large number of convex portions 43 in the lining 44 are in contact with the inner surfaces of both side heads of the liner 2.

  As shown in FIGS. 1, 2 </ b> A, and 2 </ b> B, the first buffer 3 is disposed inside the top of the liner 2, and the pair of left and right second buffers 4 are distributed inside the both sides of the liner 2. By being disposed, a ventilation path 5 is formed that surrounds the first buffer 3 from the inside of the front head of the liner 2 and continues to the inside of the back head of the liner 2. An air introduction port 6 is opened on the front head side of the air passage 5 and an air discharge port 7 is opened on the rear head side. Further, in the pair of left and right second buffer bodies 4, the overlapping outer surface 42 and inner peripheral end 46 of the lining material 44 are closed by the extending portion 30 b of the surface material 30 in the first buffer body 3. That is, the inner peripheral end 46 of the bag body 41 where the outer material 42 and the lining material 44 overlap in the pair of left and right second shock absorbers 4 is formed by the air inlet 6 and the air passage by the extending portion 30 b of the outer material 30 in the first shock absorber 3. 5 and the air outlet 7 are closed.

  When the bicycle H is worn while wearing the school helmet H configured as described above, the traveling wind is introduced between the inside of the liner 2 and the frontal head through the air inlet 6 to cool the frontal head, and then the back of the head. By flowing down the ventilation path 5 toward the side, the boundary portion between the top of the head and the temporal region is cooled, and further, the space between the inner side of the liner 2 and the back of the head is cooled to cool the back of the head, and then the air is discharged from the air outlet 7. The Thereby, the cooling effect which cools the frontal part of a helmet H wearer, the boundary part of a parietal part and a temporal region, and a occipital region is acquired.

  Further, the inner peripheral end 46 of the bag body 41 where the outer material 42 and the lining material 44 overlap in the pair of left and right second shock absorbers 4 is connected to the air inlet 6, the air passage by the extending portion 30 b of the outer material 30 in the first shock absorber 3. 5 and the air discharge port 7 can prevent the traveling wind flowing down the air passage 5 from touching the overlapping inner peripheral end 46. Therefore, since the running wind smoothly flows down the air passage 5 without being disturbed, the air permeability is improved and the cooling effect can be further enhanced.

  Furthermore, since the 1st buffer 3 is comprised by the bag body 32 which enclosed the silicone gel 33, while being able to protect the top part of a helmet H wearer by the impact absorption effect | action of the silicone gel 33, the silicone gel 33 Is easily deformed along the top of the head, so that the fit when wearing the helmet H is improved. In addition, since the silicone gel 33 has a large heat capacity and is difficult to transfer heat, the helmet H can be worn by keeping it in a cool place away from direct sunlight and hot places. At the same time, the first buffer body 3 having a temperature lower than the body temperature is fitted to the top of the head to give a cool feeling, and even if the resin shell 2 is exposed to direct sunlight, the silicone gel 33 is thermally insulated to affect the top of the head. Can be relaxed.

  Here, when soft silicone gel 33 with a penetration of 20 to 200 is enclosed in bag body 32 to form first buffer body 3, the fit when wearing helmet H is further improved. Good fit can be stably maintained. Accordingly, since the movement of the helmet H due to wind pressure, vibration, or the like can be suppressed, it is possible to avoid the field of view from being blocked by the buttocks 11 during bicycle traveling and contribute to the execution of safe traveling.

  In addition, since the pair of left and right second buffer bodies 4 are configured by the air-permeable bag body 41 in which the charcoal powder 40 is embedded and quilted, the charcoal powder 40 deodorizes the sweat odor and the moisture of the sweat. Dehumidification by adsorption makes the helmet H wearer feel refreshed, and the negative ion effect that reduces the positive ions in the air generated by the charcoal powder 40 protects the scalp by reducing irritation to the scalp, and It can exert the effect of calming fatigue and stress. Moreover, the charcoal powder 40 that has been deodorized and dehumidified can be used repeatedly because the deodorizing and dehumidifying functions are restored by natural drying.

  Here, when the pair of left and right second buffer bodies 4 are configured by charcoal powder 40 made of discarded wood and a bag body 41 in which the charcoal powder 40 is housed, the discarded wood generally includes cedar and Since a lot of soft wood such as pine is mixed, a higher shock absorbing effect than that of charcoal powder 40 made of hard wood such as firewood is obtained. Therefore, the side head of the helmet H wearer can be protected by the high impact absorbing action of the charcoal powder 40 made of discarded wood.

Example 2:
4 to 6 show a second embodiment.
As shown in FIG. 4, the left and right second buffer bodies 4 </ b> A are each composed of three bag bodies 51. Each bag 51 is disposed on the liner 2 along the circumferential direction R of the temporal region of the helmet H. In the second embodiment, as a part of each bag 51, a bag formed in a trapezoidal shape shown in FIG. 6 by a manufacturing method described later is used.

As shown in FIG. 5B, the bag body 51 has a plurality of bag portions 53 formed between a surface material 42 and a lining material 44. The said outer material 42 is comprised with the nonwoven fabric, and the lining 44 is comprised with the sheet | seat which consists of resin films etc., for example.
The bag portion 53 is formed on the outer surface 42 and is formed so as to protrude inside the helmet H. Charcoal powder 40 is housed in the bag portion 53. As shown in FIGS. 4 and 5A, each bag 53 forms a long protrusion 54 that is long in the circumferential direction R of the helmet H and short in the width direction Z (FIG. 6). The protrusions 54 are formed substantially parallel to each other, and a gap 45 is formed between the protrusions 54.

As shown in FIG. 4, the protrusions 54 of the adjacent bag bodies 51 are attached to the liner 2 so as to be continuous with each other in the circumferential direction R of the helmet H. Therefore, the gaps 45 between the protrusions 54 are continuous in the circumferential direction R, and an air flow path is formed.
Other configurations are the same as those of the first embodiment, and the same reference numerals are given to the same portions or corresponding portions, and the description thereof is omitted.

  As indicated by the arrows in FIG. 4, the traveling wind travels from the air inlet 6 toward the ventilation path 5, is introduced into each gap 45, and is discharged from the air outlet 7. On the other hand, the air introduced into each gap 45 flows down the temporal region and is discharged from the air discharge port 7. As described above, since each gap 45 is continuous in the circumferential direction R of the helmet H, the air introduced from the air introduction port 6 flows smoothly through the gap 45 toward the air discharge port 7. Thereby, the cooling effect which cools the helmet H wearer's temporal region is acquired.

  Here, the bag portion 53 is formed long in the circumferential direction R of the helmet H and short in the width direction Z. Therefore, there is no possibility that the charcoal powder 40 incorporated in the bag portion 53 is largely biased in the width direction Z (downward). Therefore, when the helmet H is worn, the bag portion 53 is in close contact with the temporal region. Does not impair the fit.

Production method:
As shown in FIG. 6, the bag body 51 can be manufactured by cutting the composite sheet 100 filled with the charcoal powder 40 between the outer material 42 and the lining material 44 into a trapezoidal shape that is in contact with each other. The bag body 51 can be manufactured.

In addition, the said bag body 51 should just be the shape in alignment with the temporal region of the liner 2, and may be formed in the fan shape.
In the above-described second embodiment, each of the left and right second buffer bodies 4A is composed of three bag bodies 51, but each of the left and right second buffer bodies 4A is composed of one bag body 51. Alternatively, two or four or more bag bodies 51 may be used.
