Description
Technical Field
The present invention relates to an impact absorbing material for a cap and an impact absorbing cap, which can protect a head from impact by providing the impact absorbing material, and more particularly, to an impact absorbing material for a cap and an impact absorbing cap, which can sufficiently exhibit both an impact absorbing effect on a head and prevention of stuffiness, and which have superior design properties as compared with a cap provided with a conventional impact absorbing material.
Background
Conventionally, a cap for protecting a head by absorbing an impact applied to the head has been used. As such a cap, for example, as disclosed in "traffic safety cap" of patent document 1, there are the following techniques: an impact absorbing member made of a synthetic foam resin sheet having a plurality of vent holes is fixed to the entire top and inner peripheral surfaces of the crown body.
However, even if the vent hole is provided, the impact absorbing member covers the head as a whole when worn, and the interior of the crown body is very hot. Therefore, there is a problem that the traffic safety cap cannot be worn for a long time.
Therefore, in recent years, technologies relating to impact absorbing caps in which prevention of stuffiness is considered have been developed, and several inventions or new implementations have been disclosed in relation thereto.
The invention disclosed in patent document 2 is characterized in that a head protector having a three-layer structure including a synthetic resin case, a shock absorber, and a head side fabric protects the front head and the side head of a wearer in a state where the head protector is attached to a hat.
In the invention having such a feature, when the elderly person falls over, the front head and the side heads which are easily damaged by the fall can be protected, and the head is not covered with the head guard as a whole, so that the head can be prevented from getting stuffy. Further, the use of the material having air permeability for the head side cloth can improve the fitting feeling of the head guard.
Next, patent document 3 discloses a utility model relating to a cap in which a space is formed in the cap to prevent stuffiness and to alleviate impact, with a name called "ventilation cap".
The utility model disclosed in patent document 3 is characterized in that it includes a vertical pad provided in a crown portion of the hat and a holder for forming a space between the hat and the vertical pad, and the hat is provided with a top air window and a rear air window in a top surface portion and a rear portion thereof, respectively.
In the utility model having such a feature, the impact on the head when an object collides against the cap can be alleviated by the gap between the cap and the longitudinal pad. In addition, air is discharged through the top air window and the rear air window through the gap, thereby preventing the head from being stuffy.

Disclosure of Invention
Problems to be solved by the invention
However, in the invention disclosed in patent document 2, since the head guard is not provided at the rear head, it is not possible to prevent injury to the rear head other than falling over. Therefore, in the invention disclosed in patent document 2, although the stuffiness prevention effect disclosed in patent document 1 is improved, the head protection effect is considered to be excessively low.
Next, in the utility model disclosed in patent document 3, the pad is disposed in a dot shape on the surface of the head, and a gap is formed around the pad, and for example, when the head hits a corner of a roadside stone due to a fall of a sidewalk, the hitting portion of the cap may be depressed, and an impact may be applied to the head as it is. Therefore, there is a problem that the head cannot be sufficiently protected from a sharp object or small stones having a small collision area. Further, since the crown portion of the cap is lifted up by the holder, the cap is bulky with respect to the size of the head, and accordingly, there is a problem that the appearance is not in good match and the design is poor.
The present invention has been made in view of the above-described conventional circumstances, and an object of the present invention is to provide an impact absorbing material for a cap and an impact absorbing cap which can sufficiently exhibit both an impact absorbing effect on a head and prevention of stuffiness, and which have excellent design properties without giving an uncomfortable feeling as compared with a cap having a conventional impact absorbing material.
Means for solving the problems
In order to achieve the above object, a first aspect of the present invention is an impact absorber for a cap to be attached to a crown body of the cap, the impact absorber for a cap including at least a front covering portion covering a front region corresponding to a front head portion of the crown body and a rear covering portion covering a rear region corresponding to a rear head portion of the crown body, and having a head top opening portion opening a head top region corresponding to a head top portion of the crown body.
In the invention having such a configuration, the front cover and the rear cover are formed of, for example, a sheet material in a planar shape made of a synthetic foamed resin body capable of absorbing impact. In contrast, since the head top opening portion does not have a base material, an opening portion is formed in the cap impact absorber.
In the invention having the above configuration, when the impact absorber for a cap is attached to the crown body of the cap, the front covering portion and the rear covering portion are provided, thereby providing an effect of protecting the front head and the rear head from an impact applied to the portions. Further, as long as the head top portion is opened, both side head covering portions covering both side head regions corresponding to both side head portions may be formed in the impact absorbing material for a cap. In addition, the front cover and the rear cover may be formed integrally with each other or separately and independently.
In the first invention, the scalp is not heated by covering the head with the impact absorbing material in the head top opening portion, and stuffiness does not occur.
Hereinafter, according to a second aspect of the invention, there is provided an impact absorber for a cap according to the first aspect of the invention, comprising a side-head covering portion covering a side-head region of the crown body corresponding to the side head, wherein a height H from a front lower edge of the front covering portion to an uppermost portion of the front covering portion is set as viewed from a side 1 When 1 is set, the height H from the rear lower edge of the rear cover to the uppermost portion of the rear cover 2 0.8 to 2.5, and a height H from the lateral lower edge of the lateral head covering part to the lowest part of the lateral upper edge of the lateral head covering part 3 Specific height H 1 Small and specific height H 2 Is small.
In the invention having such a structure, H is defined as 1 ∶H 2 The reason for 1: 0.8-2.5 is that, for example, when the wearer is walking or walking, if importance is attached to a harmful object that easily collides with the front side, H is set as 1 ＞H 2 The surface area of the front covering part can be made larger than the surface area of the rear covering part, and on the other hand, when it is important that it is difficult to support the body with the hand when the user falls over backward and the rear head is hit with a heavy load, the configuration is made as H 1 ＜H 2 The surface area of the rear cover portion can be made larger than the surface area of the front cover portion.
In addition, the height H 3 Is set as a specific height H 1 Small and specific height H 2 The small is to enlarge the open top to the lateral head region of the crown body.
In addition, the surface area of the open portion at the vertex also depends on H 1 ∶H 2 Is varied. The surface area of the open top is a value (M-M) obtained by subtracting, from the surface area M, the total surface area M of the portions of the cap impact absorber that absorb the impact, such as the front covering portion and the rear covering portion, when the cap impact absorber is assumed to be hemispherical with the surface area M.
In the invention having the above-described configuration, in addition to the function of the first invention, the ratio of the surface area of the front covering portion to the surface area of the rear covering portion can be freely changed, and the impact absorber for caps having a shape suitable for each purpose can be formed. Further, the surface area of the parietal opening portion also changes, and therefore the air permeability can be adjusted.
Next, a third invention is characterized in that the impact absorbing member for a cap is formed with a plurality of vent holes at least in part according to the first or second invention.
In the invention having such a structure, the vent hole may be formed in all of the cap shock absorbing member, in addition to a part thereof. The diameter of the vent hole is preferably several millimeters or less so that a small object such as a small stone or a golf ball can protect the head even when the small object collides with the vent hole.
In the invention of the above configuration, in addition to the effects of the first or second invention, when the cap to which the cap impact absorbing material is attached is worn, air in the interior of the crown body, which is humidified or warmed by, for example, body temperature or irradiation of sunlight, is released to the outside of the cap impact absorbing material via the vent hole. Therefore, the head is further prevented from getting stuffy.
Next, a fourth invention is according to the invention described in any one of the first to third inventions, characterized in that a projection is formed on an inner surface of the impact absorber for caps.
In the invention having such a structure, for example, a synthetic foam resin body capable of absorbing impact or a non-foaming rubber body is considered as the projection. In addition, the protrusions may be distributed more densely than other regions, in addition to being distributed evenly on the inner surface of the impact absorbing material for caps, in a region for improving the head protection effect.
In the invention of the above configuration, in addition to the effects of the invention described in any one of the first to third aspects, for example, in the case where the projection has impact absorbability, the head protective effect can be improved. Further, since the inner surface of the impact absorbing material for a cap is prevented from being closely attached to the crown body over a wide range, the stuffiness prevention effect is also improved.
A fifth aspect of the present invention is a vehicle including: a shock absorber for caps as described in any one of the first to fourth inventions; and an attachment member for attaching the impact absorbing member for a cap to the outside of the crown body, the attachment member being provided in a side head region of the crown body corresponding to the side head, at least one of both ends of the front covering portion and both ends of the rear covering portion being attached to the outside of the crown body via the attachment member, and a gap being formed between the front covering portion and the front head region and at least one of the rear covering portion and the rear head region.
In the invention having such a configuration, as the attachment member, for example, a sewing thread for inseparably sewing the cap impact absorber to the outside of the crown body, a point hook and loop fastener or a surface hook and loop fastener fastened to both the cap impact absorber and the outside of the crown body can be considered. The latter enables the impact absorber for caps to be attached to and detached from the crown body.
In the impact absorbing member for a cap, for example, both ends of the front covering portion and both ends of the rear covering portion are attached to the outside of the crown body via the attaching members. However, the impact absorbers for caps may be attached to the outside of the crown body via attachment members only at both ends of the front cover portion or only at both ends of the rear cover portion. The front cover has opposite ends in the lateral width direction of the front cover. Therefore, for example, as the lateral width of the front cover is increased, a gap is formed between the front cover and the front region, and the gap is expanded. The same applies to the rear cover.
In the invention having the above-described configuration, an impact absorbing cap having the effect of the invention described in any one of the first to fourth aspects is manufactured. In the invention having the above configuration, since the gap is formed on either the outside of the anterior region or the outside of the posterior region, the head can be prevented from getting stuffy due to the gap.
In addition, when the impact absorbing material for a cap is detachably attached to the crown body, the impact absorbing cap can be used as a normal cap by removing the impact absorbing material for a cap.
Further, for example, by changing the lateral width of the front cover and the lateral width of the rear cover, respectively, the width of each gap is changed to a large size, and in the case where the head is hard to get stuffy due to weather or seasons, the head can be kept warm by not forming the gap to be large.
ADVANTAGEOUS EFFECTS OF INVENTION
According to the first aspect of the invention, the front head and the rear head are protected from impact by the front cover and the rear cover, and the head top opening portion does not generate stuffiness, so that both the impact absorbing effect on the head and the stuffiness prevention effect can be sufficiently exhibited. Therefore, the cap with the impact absorbing material for cap attached to the band is less likely to cause discomfort due to stuffiness, and therefore the cap can be worn for a long time.
According to the second aspect of the invention, since the impact absorbing material for caps having a shape suitable for the effect of importance is formed in addition to the effect of the first aspect of the invention, it is possible to finely cope with the age and activity of the wearer.
According to the third aspect of the present invention, in addition to the effects of the first or second aspect of the present invention, the head can be further prevented from becoming stuffy by the vent hole, and thus the comfort during wearing can be improved. Further, since the impact absorbing material for a hat can be flexed in different directions around each vent hole, the impact absorbing material for a hat is easily deformed so as to follow the outer shape of the crown body when the impact absorbing material for a hat is attached to the hat. Therefore, by forming the vent hole in the material having high rigidity, it is possible to form the impact absorbing material for a cap which has high strength and can be adapted to the outer shape of the crown body.
According to the fourth aspect of the invention, in addition to the effects of the first to third aspects of the invention, the head protection effect and the stuffiness prevention effect are enhanced, and therefore, the safety and comfort when wearing a cap equipped with an impact absorbing material can be further improved.
According to the fifth invention, an impact absorbing hat having the effect of the invention described in any one of the first to fourth inventions is manufactured. Further, according to the fifth invention, the stuffiness of the head is prevented in the gap, so that the inconvenience such as the stuffiness caused by the impact absorber for caps can be surely eliminated.
Further, the width of the gap in the front-rear direction can be changed by adjusting the lateral width of the front cover and the lateral width of the rear cover, respectively. Therefore, the head can be kept warm by the impact absorber, and the same impact absorbing cap can be worn throughout the four seasons.
Further, even if a gap is formed, the thickness of the cap impact absorber is reduced, so that the cap impact absorber does not rise from the crown body, and there is little concern about a sense of incongruity in the shape of the impact absorbing cap. Thus, the design can be prevented from being impaired.

Detailed Description
Example 1
The impact absorber for a cap according to the first embodiment of the present invention will be described in detail with reference to fig. 1 to 5. Fig. 1(a) and 1(b) are a front view and a rear view of the impact absorber for caps according to example 1, respectively. Fig. 2(a) is a perspective view of the impact absorbing material for a cap of example 1 as viewed from the front upward direction, and fig. 2(b) is a perspective view of the cap as an attachment target of the impact absorbing material for a cap as viewed from the direction.
As shown in fig. 1 and 2, the impact absorber 1 of example 1 is a cap impact absorber attached to a crown 51 of a cap 50.
The impact absorber 1 includes: a front covering part 2 covering a front region 51a of the crown 51 of the cap 50 corresponding to the front of the cap wearer; a rear covering part 3 covering a rear head region 51b of the crown body 51 corresponding to the rear head of the cap wearer; and both-side head covering parts 4, 4 covering both- side head regions 51c, 51c corresponding to both-side heads of the cap wearer.
On the other hand, the crown opening part 5 has a crown region 51d corresponding to the crown of the cap wearer in the open crown body 51. The term "open" means that the sheet body 1a of the crown 51 is not covered.
As shown in fig. 2(b), the cap 50 is formed by sewing a visor 52 and a sunshade 53 to the front head region 51a and the rear head region 51b, respectively. The crown body 51 is formed by overlapping two six split fabrics, and has snap fasteners 6a ', 6 b' for fastening snap fasteners 6a, 6b described later on the front surfaces of both side head regions 51c, 51 c.
As shown in fig. 1(a) to 2(a), in the front cover 2, the front upper edge 2a has a gentle mountain shape and the front lower edge 2b has a uniform straight line when viewed from the front. The left and right ends 2c, 2c of the front cover 2 in front view and the left and right ends 3c, 3c of the rear cover 3 in rear view are integrated to form planar opposite-side head covers 4, 4. Snap fasteners 6a, 6a for attaching the impact absorbing material 1 to the crown 51 of the cap 50 are provided at both ends 2c, 2 c.
The rear upper edge 3a of the rear covering 3 has a mountain shape that rises more sharply than the front upper edge 2a of the front covering 2. The rear upper edge 3a is connected to the front upper edge 2a, and forms an outer edge of the overhead opening 5. The rear lower edge 3b of the rear covering portion 3 is connected to the front lower edge 2b so as to draw a uniform straight line, thereby forming an opening 1f of the impact absorber 1 having a substantially circular shape (see fig. 2 (a)). Snap fasteners 6b, 6b for attaching the impact absorbing material 1 to the crown 51 of the cap 50 are provided at both ends 3c, 3 c.
The both-side head covering portions 4 and 4 include: a lateral upper edge 4a formed by connecting the front upper edge 2a and the rear upper edge 3 a; and a side lower edge 4b formed by connecting the front lower edge 2b and the rear lower edge 3 b.
The top of front upper edge 2a is uppermost portion 2d, and the top of rear cover 3 is uppermost portion 3 d. The impact absorber 1 is symmetrical with respect to a straight line connecting the uppermost portion 2d and the uppermost portion 3 d. The lowermost side lower edge 4b corresponding to the lowest height among the heights from the side upper edge 4a to the side lower edge 4b is defined as the lowermost portion 4 c.
The impact absorber 1 includes: a sheet body 1a having flexibility and impact absorbability, for example, made of polyethylene foam resin, polystyrene foam resin, or the like; and a fabric 1b covering the front surface of the sheet body 1 a. The thickness of the sheet body 1a is, for example, about 2 to 4 mm. The fabric 1b of the impact absorber 1 is the same kind and color as the fabric constituting the crown body 51.
Specifically, the sheet bodies 1a constituting the front cover 2 and the rear cover 3 are each formed of one sheet, and are thermally welded to the left and right sides of each sheet body. However, the sheet body 1a of the rear cover 3 is formed into a curved surface shape by three folds 1c to 1e at equal intervals in the longitudinal direction (direction connecting the upper edge 3a and the lower edge 3b), and is easily adapted to the surface shape of the back of the wearer of the cap.
Next, the shape of the impact absorber will be described in detail with reference to fig. 3. Fig. 3(a) and 3(b) are a left side view and an a-a line view in fig. 3(a), respectively, of the case where the impact absorber for a cap of example 1 is attached to the cap shown in fig. 2 (b). Note that, in fig. 3, the same reference numerals are given to the constituent elements shown in fig. 1 and 2, and the description thereof is omitted.
As shown in fig. 3(a) and 3(b), in the impact absorber 1, the height H from the front lower edge 2b to the uppermost portion 2d of the front upper edge 2a in the front covering portion 2 is set to be higher than the height H of the front covering portion 2 1 When 1 is set, the height H2 from the rear lower edge 3b to the uppermost portion 3d of the rear upper edge 3a in the rear covering portion 3 is, for example, 1.6. That is, in the impact absorber 1, it is H 1 ＜H 2 This is a structure in which importance is attached to prevention of a heavy hit by the rear head when the user falls backward.
When the decimal second position is rounded, the height H from the lateral lower edge 4b of the side head covering portion 4 to the lowermost portion 4c of the lateral upper edge 4a of the side head covering portion 4 is increased 3 Relative to height H 1 、H 2 Are each H 3 /H 1 ＝0.7，H 3 /H 2 0.4. I.e. height H 3 Specific height H 1 Small and specific height H 2 Is small. This structure is made in order to expand the crown opening portion 5 to both side head regions 51c, 51c of the crown body 51.
When the second decimal place is rounded off, the height H from the front lower edge 2b to the rear lower edge 3b when the impact absorbing member 1 is viewed from the side is calculated 1 ～H 3 Respectively, is H relative to the length D of the bottom end face 1 /D＝0.3、H 2 /D＝0.6、H 3 and/D is 0.2. When the impact absorber 1 is viewed from above, it is shown in fig. 3(b) that it has a substantially elliptical shape and the length D corresponds to the major axis thereof.
In addition, in a side view, the uppermost portion 2d of the front covering portion 2 descends in a substantially straight line toward the rear upper edge 3a, and the rear upper edge 3a sharply bends and rises from the lowermost portion (corresponding to the lowermost portion 4c of the side head covering portion 4) having a lower height from the lowermost lower edge 2b, thereby forming the outer edge of the head top opening portion 5. Therefore, when the impact absorber 1 is attached to the cap 50, the crown region 51d of the crown body 51 and the upper portion of the front region 51a are exposed from the crown opening portion 5, while the lower portion of the front region 51a and the substantially entire rear region 51b are covered with the front covering portion 2 and the rear covering portion 3.
However, since the sheet body 1a has a thickness of about 2 to 4mm, even if the impact absorber 1 is attached to the crown body 51, the impact absorber 1 does not largely float from the crown body 51, and the three-dimensional contour of the crown body 51 in the case where the impact absorber 1 is not attached is not broken.
The front cover 2 and the front lower edge 2b thereof are spaced apart by a gap S 1 Is disposed in both the front region 51a of the crown 51 and the visor 52. The rear coating portion 3 and the rear lower edge 3b thereof are also separated by various gaps S 2 Is arranged in the posterior region 51b of the crown body 51. Through these gaps S 1 、S 2 Air permeability between the front region 51a of the crown body 51 and the front cover 2 and air permeability between the rear region 51b and the rear cover 3 are ensured. In addition, a gap S 1 、S 2 According to whether the cap 50 is actually worn or not and the volumeThe attachment positions of the snaps 6a and 6b to the both-side head covering portions 4 and 4 of the impact absorber 1 and the attachment positions of the snaps 6a 'and 6 b' (see fig. 2(b)) to the both- side head regions 51c and 51c of the crown body 51 are determined in a definite manner.
In the impact absorber 1 having the above-described structure, the impact absorber 1 is detachably attached to the crown 51 of the cap 50 via the snap fasteners 6a to 6 b'. The impact absorber 1 includes the front covering portion 2, the rear covering portion 3, and the both-side head covering portions 4 and 4, thereby protecting the lower part of the front head, the substantially entire rear head, and the lower parts of the both-side heads of the cap wearer from the impact applied to the portions. Wherein, by as H 1 ∶H 2 Since the upper portions of the crown region 51d and the front region 51a of the crown 51 are exposed from the crown opening 5 at a ratio of 1: 1.6, the temperature of the scalp near the crown is not increased, and the head of the wearer of the cap is not heated.
Further, since the impact absorbing member 1 is made of, for example, a foamed resin material having a thickness of 2 to 4mm and is light in weight, the load due to the load of the impact absorbing member 1 is reduced to a negligible level.
As described above, according to the impact absorber 1, the lower part of the front head, the substantially entire rear head, and the lower parts of both sides of the head of the cap wearer are protected from impact, and stuffiness is not generated in the vicinity of the top of the head, so that both the impact absorbing effect for the head part and the stuffiness prevention can be sufficiently exhibited. Therefore, the wearer of the cap is less likely to feel uncomfortable due to stuffiness, and can wear the cap 50 to which the impact absorber 1 is attached for a long period of time. Therefore, the wearer of the cap can continue to secure his or her safety during school hours, walking hours, or sports hours, for example.
Further, even if the impact absorber 1 is attached to the cap 50, the three-dimensional contour of the crown body 51 is not broken, and therefore, the design is superior to the conventional utility model disclosed in patent document 3, for example. Specifically, the uppermost portion 2d of the front covering portion 2 descends in a substantially straight line toward the upper rear edge 3a in a side view, and the upper rear edge 3a of the rear covering portion 3 sharply bends and rises from the lowermost portion having a lower height from the lower front edge 2b, thereby forming the outer edge of the vertex open portion 5. The outer edge shape of the crown opening portion 5 is one of important factors for determining the efficiency of preventing stuffiness and the degree of improvement in design.
In addition, when purchasing a cap having a head protection function, the purchaser firstly attaches importance to the presence or absence and degree of impact absorbability, but does not pay attention to design and price. That is, the purchaser tends to select a product having an appropriate impact absorption property, design property, and the like, and a so-called balance. In this regard, according to the impact absorber 1, as described above, the balance of the impact absorbability and the design property is good.
In addition, since the impact absorber 1 is formed by coating the sheet body 1a made of the foamed resin with the fabric 1b, the manufacturing cost thereof is not increased. Therefore, according to the impact absorbing material 1, since a good-balanced product can be obtained even from the viewpoint of price, it is expected that the impact absorbing material 1 or a cap provided with the impact absorbing material 1 can be selected by a purchaser in a larger number.
Next, the impact absorbers for caps according to the first to third modifications of example 1 will be described with reference to fig. 4. Fig. 4(a) to 4(c) are impact absorbers for hats of the first to third modified examples of the impact absorber for hats of example 1, respectively. Note that the components shown in fig. 1 to 3 are also denoted by the same reference numerals in fig. 4, and descriptions thereof are omitted. The sunshade 53 and the cloth 1b are not shown.
As shown in fig. 4(a), the impact absorber 1A of the first modification of example 1 has a plurality of vent holes 7 formed in the impact absorber 1 of example 1. In addition, instead of the snap fasteners 6a and 6b of the impact absorbing material 1, a sewn portion 8 is provided in which the impact absorbing material 1A can be fastened to the crown body 51 without being separated by sewing thread. In this case, the snap fasteners 6a 'and 6 b' provided in the crown body 51 are also omitted (see fig. 2 (b)).
In the impact absorbing member 1, the vent holes 7 are formed in a circular shape having a diameter of, for example, not 3mm, and are distributed substantially uniformly over the entire sheet body 1 a. The other impact absorber 1A has the same structure as the impact absorber 1.
In the impact absorber 1A having the above-described structure, when the cap 50 to which the impact absorber 1A is attached is worn, air inside the crown body 51, which is humidified or warmed by, for example, body temperature or sunlight irradiation, is released outside the impact absorber 1A without leakage via the vent holes 7 distributed over the entire sheet body 1A. Therefore, the stuffiness of the head of the cap wearer can be further prevented as compared with the impact absorber 1.
Further, since the diameter of the vent hole 7 is 3mm, even if a small object such as a small stone or a golf ball collides with the position of the vent hole 7, the small object hardly collides directly with the head. Therefore, the impact absorbing material 1A can improve the effect of preventing stuffiness without degrading the head protection effect as compared with the impact absorbing material 1.
Further, by providing the ventilation holes 7 in the sheet body 1a, even if the thickness of the sheet body 1a is increased, the sheet body 1a is easily bent around the ventilation holes 7. Therefore, by changing the thickness and the composition ratio of the sheet body 1a, even if the rigidity of the sheet body 1a is increased, the flexibility of the sheet body 1a can be ensured by the vent hole 7. Therefore, according to the impact absorber 1A, the head protection effect can be indirectly improved while maintaining the stuffiness prevention effect. At the same time, the sheet body 1A with increased flexibility still exhibits the advantageous effect that the impact absorber 1A is easily adapted to the shape of the head of the cap wearer, and therefore there is no possibility that the impact absorber 1A is enlarged and lacks in design.
The vent holes 7 are covered with the fabric 1b, and thus are not clearly visually observed, and the appearance of the fabric is hardly visually impaired by the vent holes 7. The action and effect of the other shock absorber 1A are the same as those of the shock absorber 1, respectively.
Next, as shown in fig. 4(B), the impact absorber 1B of the second modification of example 1 is such that the height H of the rear covering portion 3 is set to be higher than that of the rear covering portion 3 when viewed from the side 2 (height from the rear lower edge 3b to the uppermost portion 3 d) with respect to the height H of the front cover 2 1 (height from front lower edge 2b to uppermost portion 2 d) is 1.8, and H 3 /H 1 ＝0.6、H 3 /H 2 0.3 of the component. That is, in the impact absorber 1B, the same as the impact absorber 1, the value is H 1 ＜H 2 Emphasis is placed on preventing pounding of the back head. Accompanied by this, it becomes H 1 /D＝0.3、H 2 /D＝0.5、H 3 and/D is 0.2. Further, H 1 ～H 3 、H 3 /H 1 、H 3 /H 2 、H 1 /D～H 3 The value of/D is the second rounding of the decimal point (the same applies to FIG. 4 (c)).
However, in the impact absorber 1B, the height H is set to be higher than the height H 1 ～H 3 Are lower than in the case of the impact absorber 1, and the surface area of the overhead open portion 5 is further expanded. However, the head protection effect of the impact absorber 1B is only slightly reduced in the surface areas of the front covering portion 2 and the rear covering portion 3 of the impact absorber 1B compared with the impact absorber 1, and thus the reduction in the head protection effect is also extremely small.
In the impact absorbing material 1B, any of the snaps 6a and 6B of the impact absorbing material 1 is omitted, and the remaining one is disposed at a height H when viewed from the side 1 Corresponding lower front edge 2b and height H 2 The corresponding rear lower edge 3 b. In addition, the snap fasteners 6a 'to 6 c' of the crown body 51 are set to have a smaller interval than in the case of embodiment 1. Therefore, the gap S can be changed by fastening the snap 6a of the impact absorbing member 1B to any of the snap 6a 'to 6 c' of the crown 51 1 、S 2 The ratio of (a) to (b). Further, in fig. 4(B), a state where the snap fastener 6a of the impact absorbing member 1B is fastened to the snap fastener 6B' of the crown body 51 is shown. The structure of the impact absorber 1B other than that is the same as the impact absorber 1.
In the impact absorber 1B having the above-described structure, the surface area of the crown open portion 5 is expanded as compared with the impact absorber 1, and the head of the cap wearer can be further prevented from getting stuffy.
In the impact absorbing material 1B, the fastening of the snap 6a of the impact absorbing material 1B to the snap 6a 'to 6 c' of the crown 51 is changedPosition of enabling the gap S 1 、S 2 The air permeability between the front region 51a of the crown body 51 and the front cover 2 and the air permeability between the rear region 51b and the rear cover 3 can be adjusted by changing the volume ratio of (a). Therefore, according to the impact absorber 1B, the effect of head protection is reduced less than that of the impact absorber 1, and the effect of preventing stuffiness in the entire cap 50 can be improved or the degree of the effect of preventing stuffiness can be changed for each of the front region 51a and the back region 51B. The other actions and effects of the impact absorber 1B are the same as those of the impact absorber 1.
Next, as shown in fig. 4(C), in the impact absorber 1C of the third modification of example 1, the height H of the rear covering portion 3 is set to be equal to or less than the height H of the rear covering portion 3 2 Height H relative to the front cladding part 2 1 Is set to 1.0 and H 3 /H 1 ＝H 3 /H 2 0.3 of the component. That is, in the impact absorber 1C, H is formed 1 ＝H 2 The importance is attached to the prevention of the thump of the front head and the thump of the rear head to the same extent. However, in the impact absorber 1C, the height H is set to be larger 3 The height H3 of the impact absorber 1 is lower, so the surface area of the overhead opening 5 is ensured to the same extent as in the case of the impact absorber 1. In addition, accompanying this, it is H 1 /D＝0.4、H 2 /D＝0.4、H 3 /D＝0.1。
The impact absorber 1C includes a substantially elliptical surface fastener 9a instead of the snap fasteners 6a and 6b of the impact absorber 1. On the other hand, instead of the snaps 6a 'and 6 b', the crown body 51 includes substantially rectangular surface fasteners 9b having a larger area than the surface fastener 9a in the both side head regions 51c and 51c, respectively. Therefore, by fastening the surface fastener 9a of the impact absorber 1C to an arbitrary position of the surface fastener 9b of the crown body 51, the gap S can be changed 1 、S 2 The ratio of (a) to (b). However, if the surface fastener 9a is fastened at a position higher than the range of the surface fastener 9b, the gap S can be particularly set 1 、S 2 The volume of (b) increases in the height direction (the direction away upward from the crown body 51). Of other impact absorbers 1CThe structure is the same as that of the impact absorber 1.
In the impact absorber 1C of the above structure, the front head portion and the rear head portion can be protected from impact to the same extent while maintaining the surface area of the crown open portion 5 as compared with the impact absorber 1. Therefore, for example, when the impact absorbing material 1C does not have a particular tendency to be seen in the falling direction, the impact absorbing material can be used appropriately.
In the impact absorber 1C, the fastening position of the surface fastener 9a of the impact absorber 1C to the surface fastener 9b of the crown body 51 is variously changed. Therefore, the gap S can be made 1 、S 2 Since the volume of (b) also changes in the height direction, the air permeability between the front region 51a of the crown body 51 and the front cover 2 and the air permeability between the rear region 51b and the rear cover 3 can be further adjusted. The action and effect of the other shock absorber 1C are the same as those of the shock absorber 1, respectively.
As described above, in the case of fig. 4(a) to 4(c), H is 1 The range of/D is 0.3-0.4, H 2 The range of/D is 0.4-0.6. In addition, H 3 The range of/D is 0.1 to 0.2. Wherein, as in the impact absorber 1A in FIG. 4(a), when H 2 when/D is 0.6, H is set to H although the uppermost part 3D of the rear cladding 3 reaches the vicinity of the top of the crown 51 1 D and H 3 D average ratio H 2 The value of/D is 0.6 or less, so that the surface area of the vertex open portion 5 is ensured to be constant or more.
Hereinafter, an impact absorber for a cap and an impact absorbing cap according to a fourth modification of example 1 will be described with reference to fig. 5. Fig. 5(a) and 5(b) are respectively a perspective view of a cap impact absorbing material according to a fourth modification of the cap impact absorbing material of example 1 as viewed from the front upper direction, and (b) is a C-C line cross-sectional view in (a) when the cap impact absorbing material is attached to the cap shown in fig. 2 (b). Note that, in fig. 5, the same reference numerals are given to the constituent elements shown in fig. 1 to 4, and the description thereof will be omitted. In fig. 5(b), the sunshade 53 is not shown.
As shown in fig. 5(a) and 5(b), a shock absorber 1D of a fourth modification of example 1 is a member in which a plurality of projections 12 are formed on the inner surface of the shock absorber 1 of example 1 with a space therebetween.
The projection 12 has a solid structure having a cylindrical shape, and is formed integrally with the sheet body 1a of the impact absorbing member 1 by pressing a foamed resin material that is the same as the sheet body 1 a. Alternatively, one end surface of the projection 12 may be fastened to the sheet body 1a by an adhesive or heat welding.
The projections 12 have the same height h (see fig. 5(b)) and can secure the gap S when the impact absorber 1D is attached to the cap 50 1 、S 2 The size of the cap 51 of the cap 50 and the size of the impact absorber 1D are preferably determined in consideration of the above.
The protrusions 12 are distributed substantially uniformly over the entire inner surface of the impact absorber 1D, but are not preferably provided around the snap fasteners 6a, 6 b. Means for avoiding the snap fasteners 6a, 6b from becoming difficult to engage with the snap fasteners 6a ', 6 b' of the cap 50. In addition, the height h of the protrusions 12 distributed on the inner surfaces of the front cover 2 and the rear cover 3 may be set to be higher than the height h of the protrusions 12 distributed on the inner surfaces of the both head covers 4 and 4. The projections 12 may have an irregular shape, other than a cylindrical shape, as long as they have a height h, in addition to an elliptical or polygonal shape in cross section. The longitudinal section (the sectional shape in the height direction) of the protrusion 12 may be a columnar shape, a spindle shape, or a trapezoidal shape. That is, the projections 12 may be in a form in which they are not easily bent or flexed in the height direction.
In the impact absorber 1D having the above-described structure, when the impact absorber 1D is attached to the cap 50, the top portions of the plurality of projections 12 abut against the crown 51 of the cap 50. Thus, the plurality of protrusions 12 serve as the gaps S 1 、S 2 The pad in (1) plays a role.
Therefore, according to the impact absorbing member 1D, since the projection 12 functions as a spacer, for example, when strong wind blows, the gap S 1 、S 2 Does not disappear, and can stably exert the stuffiness-preventing effect. In addition, the projection 12 has the advantages ofThe head protection effect can be improved because of the shock absorption. The other actions and effects of the impact absorber 1D are the same as those of the impact absorber 1.
Example 2
Hereinafter, the impact absorbing cap of example 2 will be described with reference to fig. 6. Fig. 6(a) and 6(B) are a sectional view taken along line B-B in fig. 3(B) and a sectional view taken along line D-D in fig. 6(a), respectively, of the impact absorption cap of example 2. Note that, in fig. 6, the same reference numerals are given to the constituent elements shown in fig. 1 to 5, and the description thereof will be omitted. In addition, the sunshade 53 of the cap 50 is not shown.
As shown in fig. 6(a) and 6(b), the impact absorbing cap 10 of example 2 includes an impact absorbing material 1 and a mounting member 11 for mounting the impact absorbing material 1 to the outside of the crown body 51.
Specifically, the attachment member 11 is a snap fastener 6a to 6 b' shown in fig. 1 to 2.
Specifically, both ends 2c, 2c of the front cover 2 and both ends 3c, 3c of the rear cover 3 are connected to both side head regions 51c, 51c via snap fasteners 6a to 6 b'. Thus, a gap S is formed between the back surface of the front cover 2 and the front surface of the front region 51a of the crown 51 1 And a gap S is formed between the back surface of the back coating part 3 and the front surface of the back head region 51b 2 。
Wherein in the gap S 1 The impact absorbing member 1 is attached to the front lower edge 2b via snap fasteners 6a to 6 b' at a position slightly raised from the visor 52. In addition, tucks 54 are formed in the back head region 51b of the crown body 51, and the back head region 51b can be expanded and contracted in the left-right width direction.
In the impact absorbing cap 10 having the above-described structure, in addition to the function of attaching the impact absorbing material 1 to the cap 50 as described above, air can flow in the gap S 1 、S 2 Is passed through.
Wherein in the gap S 1 In, as shown by arrow X 1 Air A discharged from the interior of the crown body 51 through the front region 51a 1 For example in the gap S 1 The inner part of the water tank rises upwards,preventing retention in the interior thereof.
Further, since the impact absorber 1 is attached so that the front lower edge 2b slightly floats from the visor 52, the wind blowing toward the impact absorber 1 passes through the gap between the front lower edge 2b and the visor 52 and the air a 1 And (6) merging. By this confluence, the wind from the outside is directed to the air A 1 Cooling is performed while in the gap S 1 And the inner part rises. Therefore, prevention of air A can be promoted 1 The effect of retention of (2).
And, in the gap S 2 In, as shown by arrow X 2 Air A shown being released from the interior of crown 51 through rear head region 51b 2 In the gap S 2 The inner part of the container is prevented from being retained by the inner part of the container when the container is lifted or lowered.
Further, according to the formation of the gap S 1 、S 2 The front cover 2 and the rear cover 3 can be largely deformed to effectively absorb the impact, and thus the head protection effect can be improved.
According to the impact absorbing cap 10, in addition to the effect of the case where the impact absorbing member 1 is attached to the cap 50 as described above, the gap S is formed 1 、S 2 Can prevent air A 1 、A 2 Stays in the gap S 1 、S 2 Thereby preventing hot gas from filling the gap S 1 、S 2 Inside. Therefore, according to the impact absorption cap 10, the gap S can be utilized 1 、S 2 To improve the effect of preventing stuffiness.
Further, according to the impact absorbing cap 10, even when the attachment position of the impact absorbing member 1 to the crown body 51 is determined in a definite manner, the gap S can be made small by adjusting the lateral width of the front covering portion 2 (the length between the both ends 2c, 2c) and the lateral width of the rear covering portion 3 (the length between the both ends 3c, 3c) separately 1 、S 2 In the front-rear direction (connection height H shown in FIG. 3 (a)) 1 And height H 2 Linear direction) of the strip. Thus, the gap S can be adjusted according to the weather and the season 1 、S 2 Thereby improving the effect of preventing stuffiness.
In addition, when the head is less likely to be stuffy due to low temperature, the head can be kept warm without forming a large gap. Further, as in the case of the impact absorbers 1B, 1C of the second and third modifications of embodiment 1, the mounting member 11 can adjust the gap S during use even when the mounting position of the impact absorber 1 to the crown body 51 can be changed 1 、S 2 The volume of (2), and thus the convenience can be further improved.
The impact absorber and the impact absorbing cap of the present invention are not limited to the structures shown in the examples. For example, in the impact absorbers 1, 1A to 1D, H 1 ∶H 2 1: 0.8-2.5, provided that H is 3 Ratio H 1 Is small and has a ratio of H 2 Small, then H 1 ～H 3 The ratio between the two may be a combination other than that shown in fig. 3 and 4(a) to 4(c), and the two- side headings 4 and 4 may be replaced with, for example, a tape not including the sheet body 1 a. In addition, the vent hole 7 of the impact absorber 1A may be omitted in the both-side head covering portions 4, 4. The vent holes 7 may not be substantially circular, and may be unevenly distributed in the sheet body 1 a.
In addition, in the impact absorbing cap 10, the gap S may not be formed depending on the mounting position of the impact absorbing material 1 to the crown body 51 1 、S 2 Any one of (1).
In addition, instead of providing the front lower edge 2b of the front cover 2 as a uniform straight line, a convex portion may be provided so that the front lower edge 2b floats from the visor 52 regardless of the snap fasteners 6a to 6 b'. For example, it is conceivable to form the front lower edge 2b in a wave shape or provide a protruding portion protruding downward from the front lower edge 2b to form the protruding portion.
This is to prevent wind from passing through the gap between the front lower edge 2b and the visor 52 when, for example, the front cover 2 is pressed by strong wind and the front lower edge 2b thereof collides with the visor 52. If the convex portion is provided on the front lower edge 2b, even if the front lower edge 2b collides with the visor 52, a gap is likely to remain therebetween, and it is considered that the amount of wind passing through the gap can be kept constant or more.
In this case, the wind blowing toward the impact absorber 1 flows into the gap between the front lower edge 2b and the visor 52, and the effect of preventing stuffiness can be reliably exhibited. When a hat 50 is assumed to be a peaked hat having a visor over the entire circumference of the crown body 51, the projection may be provided on the rear lower edge 3b of the rear cover 3 in addition to the front lower edge 2 b.
Industrial applicability
The present invention can sufficiently exhibit both impact absorption effect for the head and prevention of stuffiness, and can be used as an impact absorption cap having excellent design.
