Description

  The present invention relates to a double hat provided with a plurality of ridges in order to block light from the sun.

  Conventionally, so-called sunshades such as fishing hats, baseball hats, straw hats, sun visors, etc. are generally used to block the direct sunlight from the sun and reduce the glare caused by direct sunlight. A hat is known. This sunshade hat is known to include a mounting portion that is mounted on a person's head and an upper heel that is provided at least in front of the mounting portion and covers the eyes of the person wearing the hat. And the upper eyelid in this sunshade hat blocks the direct sunlight from above, so that the direct sunlight is not directly inserted into the wearer's eyes. Thereby, it is avoided that the direct sunlight of the sun shines on the wearer wearing the sun hat, and the wearer is prevented from feeling dazzling.

  However, sunshades that have an upper eyelid that covers the eyes of the wearer function effectively against direct sunlight from above, but the light that illuminates the eyes of the wearer wearing the sunshade is from above. Not limited to direct sunlight. For this reason, there is a problem that cannot be prevented with sunshades for sunsharing of those who are fishing especially during the day and those who are always engaged in outdoor work. That is, for example, in the case of a fisherman, direct sunlight may hit the sea surface, and the sunlight reflected by the sea surface may illuminate the eyes and feel dazzle by the light. In addition, for those who are working outdoors, the reflected sunlight that bounces off the road surface may enter the eyes and feel dazzling. In particular, the reflected sunlight reflected by the snowy surface in winter is relatively strong in ultraviolet rays, and when such reflected sunlight illuminates the eyes for a relatively long time, the eyes caused by ultraviolet rays commonly called “Yukime” May cause keratitis.

  In order to protect the eyes of those who wear hats by blocking such reflected sunlight, a slot is provided on the upper face of the hat to fit the upper eyelid of the hat, and attached to the upper eyelid of the hat. A possible awning mask has been proposed (see, for example, Patent Document 1). In this sunshade mask, when the slot is inserted into the upper heel of the hat, the mask is set to cover the front face of the face vertically, and shields light other than direct sunlight from above.

JP 2007-284853 A

  However, the conventional sunshade mask is a detachable mask on a hat having a heel, and is carried separately from the original hat and attached to the hat when necessary. For this reason, even if it is not necessary for such an awning mask, it is necessary to carry it with the hat, and it is relatively troublesome, and the awning mask is attached to the hat. There was also a problem that the removal itself was troublesome. In addition, since this mask covers the front of the face, if the mask becomes dirty, the front field of view is blocked.

  Moreover, since this sunshade mask is mounted on the heel of the hat, a gap is formed between the face of the person wearing the hat on the head and the mask. For this reason, in the case of anglers and outdoor workers standing in the same place for a long time, reflected sunlight from the water surface or reflected sunlight from beneath the hot air on the road surface is between the face and its face. Since it may enter and illuminate the eyes, there is still a problem to be solved that the eyes are not protected and the glare cannot be avoided by the reflected sunlight.

  The purpose of the present invention is not only to block the direct view from the sun located above, but also to block the reflected sunlight from below reflected by the direct sunlight hitting the sea surface and the ground surface, without blocking the forward view, The object is to provide a double hat that can avoid glare caused by them.

  The present invention includes a mounting portion to be mounted on the head, an upper heel provided at least in front of the mounting portion, and a lower portion positioned below the upper heel and spaced apart from the upper heel. A double hat with a scissors.

  It is preferable that the lower heel is provided on the mounting portion via an elastic body, or is swingably provided on the mounting portion. Further, the lower ridge may be configured to be superposed on the upper ridge, and may further include locking means for locking the lower ridge superimposed on the upper ridge to the upper ridge. And it is also preferable that a lower side collar is formed in the mountain shape which the center of the width direction rises upwards.

  In addition, the “double hat” in this specification refers to a so-called sun visor that is worn around the head and does not cover the top of the head, in addition to a baseball cap that covers the entire head. Including things.

  The compound hat according to the present invention includes the upper eyelid covering the upper front of the field of view, so that the upper eyelid can block the direct sunlight from the sun, thereby avoiding glare. It also has a lower ridge that covers the lower front of the field of view, so that direct sunlight from the sun hits the sea surface and the upper surface of the ground, and the reflected sunshine that is received from directly below is blocked by the lower heel to avoid glare caused by reflected sunlight. can do.

  Also, in the double hat according to the present invention, the upper and lower eyelids are provided in advance on the mounting part to be worn on the head, so that it is carried separately from the original hat like a conventional sunscreen. There is no. And, if it is provided with a locking means for locking the lower heel superposed on the upper heel to the upper heel, even if the lower heel is not required, the lower heel can be an obstacle Absent. For this reason, for example, the situation which forgets a lower heel can be avoided.

  Furthermore, the double hat according to the present invention includes an upper heel that covers the upper front of the visual field and a lower heel that covers the lower front of the visual field, but there is nothing that blocks the front of the visual field. For this reason, the field of vision in front of the person wearing this double hat is not blocked by the double hat of the present invention.

It is a side view of a person wearing a double hat according to an embodiment of the present invention. It is a front view of the person wearing the double hat. It is the perspective view which looked at the double hat from diagonally upward. It is the perspective view which looked at the double hat from diagonally downward. It is a side view of a person wearing a double hat according to another embodiment of the present invention. It is a front view of a person wearing the other double hat. It is the perspective view which looked at the another double hat from diagonally upward. It is the perspective view which looked at the another double hat from diagonally downward.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  1 to 4 show a double hat 10 of the present invention. The double hat 10 of the present invention includes an attachment portion 12 attached to the head (FIGS. 1 and 2). The mounting portion 12 in the figure has a triangular cloth piece 13 (strengthen) composed of six mesh fabrics (three-dimensional three-dimensional structure fabrics), and the oblique sides thereof are sewn and joined together. It is formed in a bowl shape so as to match the shape, and the apex angles of all the triangular cloth pieces 13 are bound by the insulating fasteners 14 (FIGS. 1 to 3) in the portion that becomes the top of the head. Yes. In addition, synthetic fibers such as nylon, natural fibers such as cotton, and mixed fibers of natural fibers and synthetic fibers are generally used for the triangular cloth piece 13, but felt, leather, etc. are also used when the mesh fabric is not used. be able to.

  In addition, the two triangular cloth pieces 13 located at the back of the mounting portion 12 have corners on the bottom so that a semicircular cutout portion 15 is formed on the back of the mounting portion 12 as shown in FIG. Only a quarter arc shape is cut out. This notch portion 15 is provided to adjust the circumferential length of the lower end of the mounting portion 12 in accordance with the size around the head of the double hat 10 user. A male detachable tape 16 and a female detachable tape 17 are attached to the notch portion 15 so as to extend from the lower end of the mounting portion 12 around the head. The circumferential length of the lower end of the mounting portion 12 can be adjusted by changing and adjusting the engaging position of the male removable tape 16 and the female removable tape 17 in the longitudinal direction. Yes.

  The configuration of the mounting portion 12 in this embodiment is substantially the same as the mounting portion 12 of a conventional baseball cap or the like, and as shown in FIG. 4, two triangular cloth pieces on the front side of the mounting portion 12 A thin fabric 19 is lined on the inner surface side of 13, and a reinforcing cloth 18 having a predetermined width is sewn along the sewn portion on the inner surface side where the triangular cloth pieces 13 are sewn and joined. Further, a belt-like absorption band 20 for absorbing forehead sweat is sewn on the inner peripheral side of the lower end edge of the mounting part 12 excluding the notch part 15. Although not shown, the absorbent band 20 can be detachably attached to the inner peripheral side of the lower end edge of the mounting portion 12 using a surface fastener without sewing. If the absorbent band 20 is detachable, even if dirt is attached to the absorbent band 20 by using the double hat 10, it can be easily removed and washed.

  As shown in FIGS. 1 to 4, such a mounting portion 12 is provided with an upper ridge 21 that blocks light on the front surface side thereof. The upper eyelid 21 is provided on the mounting portion 12 so as to cover the upper front of the field of view of the wearer wearing the mounting portion 12 on the head (FIGS. 1 and 2). In the same manner as in the prior art, the upper ridge 21 is made of a thin core material (not shown) made of a resin having a slight collapse, such as polyethylene, in a meniscus shape, and is warped and covered with a cloth or the like. Are illustrated. And the upper side collar 21 which comprises this meniscus shape, the cloth which coat | covered the core material in the base end side is pinched | interposed between the lower end edge part of the mounting part 12, and the absorption band 20, and the lower end of the mounting part 12 It is sewn together with the absorbent band 20 at the edge. Then, two male hooks 22 facing downward are attached to the lower part of the upper flange 21 in this example at a predetermined interval in the front-rear direction at the center in the width direction.

  The double cocoon cap 10 according to the present invention is provided with a lower heel 23 positioned below the upper heel 21 and sandwiching the wearer's view from above and below together with the upper heel 21 with a predetermined distance from the upper heel 21. To do. That is, the lower ridge 23 covers the lower front of the field of view of the wearer wearing the mounting portion 12 on the head. The lower ridge 23 in this embodiment is a thin polyethylene core (see FIG. (Not shown) is formed in a meniscus shape, and is warped and covered with a cloth or the like, and a contact band 24 that contacts the face of the wearer is provided on the base end side of the lower eyelid 23. . The lower heel 23 is formed with a recess 23a that avoids contact with the wearer's nose column at the center of the base end side, and a contact band 24 that stands up on the base end side is also provided in the recess 23a. . The abutment band 24 is made of the same cloth as the cloth on the outer surface of the lower eyelid 23 so as not to cause an uncomfortable appearance when it comes into contact with the face. The abutment band 24 is provided along the base end side of the lower eyelid 23 so as to be orthogonal to the lower eyelid 23, on both sides of the wearer's nose and between the eyes and cheeks or It is provided so that surface contact can be made on the cheek.

  One end of a belt-like rubber cord 26, which is an elastic body, is attached to both sides of the contact belt 24, and the other end of the rubber cord 26 is an absorption band 20 on the inner side of the lower end of the mounting portion 12 and is positioned on the temporal region. It is attached to the part to do. Accordingly, the lower heel 23 is provided on the mounting portion 12 via the elastic band 26 that is an elastic body, and the lower heel 23 is rotated with respect to the mounting portion 12 by the elastic band 26 that is an elastic body. It is configured to be movable. In the state where the contact band 24 is between or in contact with the wearer's eyes and cheeks, the rubber strap 26 pulls both ends of the contact band 24 in the temporal direction. It is maintained between the wearer's eyes and cheeks or in contact with the cheeks, whereby the lower eyelid 23 is configured to be maintained on the face while protruding forward from the lower side of the wearer's eyes. (FIGS. 1 and 2).

  A female hook 25 that can be engaged with the male hook 22 is attached to the upper surface of the lower hook 23 that faces the male hook 22 provided on the upper hook 21. The female hook 25 attached to the lower side hook 23 is configured to engage with the male hook 22 of the upper side hook 21 and to superpose the lower side hook 23 on the upper side hook 21 and fix it. For example, the male hook 22 and the female hook 25 are made of an insulating material such as a plastic in order to prevent a lightning strike from occurring when the double hat 10 is worn outdoors.

  As shown in FIGS. 3 and 4, in the double cap 10 configured as described above, the lower hook 23 is superposed on the upper hook 21, and the female hook 25 is engaged with the male hook 22. The lower ridge 23 is fixed to the upper ridge 21 in a polymerized state. When the mounting portion 12 of such a double hat 10 is mounted on the head, both the lower heel 23 and the upper heel 21 that overlap each other are positioned above the field of view of the wearer. For this reason, the upper eyelid 21 and the lower eyelid 23 block the direct sunlight from directly above and prevent the light from directly illuminating the wearer's eyes, thereby avoiding glare caused by it.

  On the other hand, it is necessary to avoid the sunlight reflected by the bounce from the bottom when the sunlight from the sun hits the sea surface or the road surface, for example, for anglers who stay outdoors all day long and for traffic control people in road construction. is there. For this purpose, as shown in FIGS. 1 and 2, the male hook 22 is detached from the female hook 25, the lower eyelid 23 is separated from the upper eyelid 21, and the lower eyelid 23 is moved to the lower side of the eye. The abutment band 24 is brought into contact with or between the eyes and cheeks on both sides of the wearer's nose by the elastic force of a certain band-shaped rubber cord 26, and the lower eyelid 23 projects forward from the lower side of the wearer's eyes. Fix in the state. In this way, since it is a simple operation of simply detaching the female hook 25 and lowering the lower heel 23, it is relatively easy as compared with the conventional case where it is necessary to attach the sunshade to the hat. The lower eyelid 23 can be fixed in a state of protruding forward from the lower side of the eyes, and the operation itself is not troublesome. Then, the lower ridge 23 located under the eyes hits the sea surface or road surface, blocks the reflected sunlight due to rebounding from below, and prevents the light from directly illuminating the wearer's eyes, thereby reducing glare.

  In particular, in the lower eyelid 23, the contact band 24 provided on the base end side facing the face of the lower eyelid 23 is on both sides of the wearer's nose due to the elastic force of the belt-like rubber cord 26, and the eyes and cheeks The lower eyelid 23 together with the contact band 24 can effectively shield the reflected sunlight that enters from around the nose. For this reason, the situation where the reflected sunlight illuminates the wearer's eyes can be effectively avoided.

  In the double hat 10 of the present invention, since the upper heel 21 and the lower heel 23 are provided in advance in the mounting portion 12 to be mounted on the head, unlike the conventional awning face, separate from the original hat. There is nothing to carry around. For this reason, for example, the situation which forgets the lower side collar 23 is avoided.

  Furthermore, although the double helmet 10 of the present invention includes the upper ridge 21 that covers the upper front of the field of view and the lower ridge 23 that covers the lower front of the field of view, there is nothing that blocks the front of the field of view. For this reason, the field of vision in front of the person wearing the double hat 10 is not blocked by the double hat 10 of the present invention.

  In the above-described embodiment, the mounting portion 12 formed into a hook shape by sewing and joining the six triangular cloth pieces 13 is described. However, this is an example of the mounting portion 12, and It is not limited to anything. Therefore, the number of the triangular cloth pieces 13 is not limited to six, and the shape thereof is not limited to that of a substantially isosceles triangle, and the mounting portion 12 covers the head and is mounted on the head. As long as the shape and structure are arbitrary.

  In the above-described embodiment, the contact band 24 that contacts the wearer's face is also formed in the recess 23a of the lower heel 23. However, the contact band 24 is not provided in the recess 23a. May be.

  5 to 8 show another embodiment of the present invention.

  5 to 8 is a so-called sun visor, which is a so-called sun visor, and has a half-moon-shaped upper ridge 41 and an upper side of the upper ridge 41 in a state of being erected on the base end side. There is a mounting portion 42 for fixing the collar 41 to the head. The mounting portion 42 is provided upright on the proximal end side of the upper side collar 41, and has a U-shaped body portion 43 that comes into contact with the wearer's forehead and temporal region, and both end portions of the body portion 43. The size adjustment band 44 made of cloth extends from each of the two, and the size adjustment band 44 is attached to the end portion of the main body part, and is engaged with the left and right size adjustment bands 44 to form an annular shape together with the main body part 43. It is configured to make. The main body 43 in the figure has, for example, a length of about 50 cm from the frontal region to the temporal region, and its width is from about 7-8 cm to about 3-5 cm from the frontal region to the temporal region. An example of a taper formed gradually is illustrated.

  As shown in FIG. 8, the size adjustment band 44 in this embodiment is provided to extend from both ends of the main body 43, and has a length of about 3 to 7 cm with a rectangular frame-shaped ring 45 attached to the tip. The male detachable tape 46 is sewn on the outer short side 44a and the outer peripheral side in the range of about 5 to 7 cm from the distal end, and the female removable tape 47 is sewn on the outer peripheral side in the range of about 4 to 6 cm from the proximal end. It is composed of a long band 44b having a total length of about 10 to 18 cm, and is folded at an appropriate position with the long band 44b passing through the ring 45 to engage the male and female removable tapes 46 and 47, The size adjustment band 44 and the main body 43 are configured so that the circumferential length of the annular mounting portion 42 can be adjusted.

  The main body 43 and the upper flange 41 of the mounting portion 42 are molded products and are integrally formed. That is, the main body 43 and the upper collar 41 are made of plastic, and the upper collar 41 formed in a meniscus shape is provided with its proximal end connected to the mounting section 42. The so-called side visor type double cap 40 has a lower heel 53 below the upper heel 41 so as to sandwich the field of view of the wearer with the mounting portion 42 attached to the head from above and below. 41 with a predetermined interval. The lower ridge 53 in this embodiment is formed in a meniscus shape similar to the upper ridge 41, but its outer shape is smaller than the upper ridge 41.

  The lower ridge 53 is formed with an extension portion 55 that extends on both sides of the base end side and forms a U-shape together with the lower ridge 53. Even in the lower flange 53 and the extension 55, they are made of plastic made by resin molding, and these are integrally formed. Further, pivot portions 43a bulging downward from the main body portion 43 are formed on both sides of the mounting portion 42, that is, on the side of the head near the wearer's ears. The distal end portion of the extension portion 55 is pivotally supported, and the lower flange 53 is provided on the mounting portion 42 so as to be swingable.

  Further, as shown in FIG. 6, the lower ridge 53 is formed in a mountain shape in which the center in the width direction rises upward. By forming the lower heel 53 into a mountain shape, a situation in which the nose column and the lower heel 53 are in direct contact with the wearer of the double hat 40 is configured to be avoided. A female hook 57 is provided at the center of the lower surface of the upper ridge 41, and the upper surface of the lower ridge 53 facing the female hook 57 of the upper ridge 41, that is, the top surface of the lower ridge 53 forming a mountain shape. Is attached with a male hook 56 that can be engaged with the female hook 57. Then, the lower hook 53 is superposed on the upper hook 41, and the male hook 56 and the female hook 57 are engaged with each other so that the lower hook 53 is superposed on the upper hook 41. Configured (FIG. 8).

  On the other hand, when the male hook 56 is detached from the female hook 57 and the engagement is released, the upper heel 41 formed integrally with the main body 43 of the mounting portion 42 is maintained in a position covering the upper front of the wearer's field of view. However, the lower side collar 53 in which the distal end portion of the extension portion 55 is pivotally supported by the pivot portion 43a swings around the pivot point by its own weight and moves downward. And the lower side collar 53 contacts the extension part 55 in the state which reached the position which covers a wearer's visual field front lower direction in the pivotal support part 43a, and prevents that the lower side collar 53 moves below further. A stopper member 43b and an engagement piece (not shown) for maintaining the extended portion 55 in contact with the stopper member 43b in a state of being in contact with the stopper member 43b are provided.

  In the double cap 40 configured as described above, normally, as shown in FIGS. 7 and 8, the lower hook 53 is superposed on the upper hook 41 and the female hook 57 is engaged with the male hook 56, The lower ridge 53 is fixed to the upper ridge 41 in a superposed state. When the mounting portion 42 of such a sun visor type double cap 40 is mounted on the head, both the lower heel 53 and the upper heel 41 that overlap each other are positioned above the field of view of the wearer 42. . For this reason, the upper eyelid 41 and the lower eyelid 53 prevent direct sunlight from directly above and prevent the light from directly illuminating the wearer's eyes, thereby avoiding glare caused by it.

  On the other hand, on a day with strong sunshine, as shown in FIGS. 5 and 6, the male hook 56 is detached from the female hook 57, the lower hook 53 is separated from the upper hook 41, and the distal end of the extension 55 is connected to the pivot 43a. The lower rod 53 on which the part is pivoted is rotated around its pivot point by its own weight and moved downward. And the extension part 55 is made to contact | abut to the stopper member 43b, and it is made to maintain in the state which reached the position which the lower side collar 53 covers a wearer's front view downward. In this way, since it is a simple operation of simply detaching the female hook 57 and lowering the lower eyelid 53, the lower eyelid 53 can be moved forward from the lower side of the eye relatively easily as compared with the conventional awning face. It can be fixed in a protruding state, and its operation itself is not troublesome. Then, the lower ridge 53 fixed in a state of protruding forward from the lower side of the wearer's eye blocks the reflected sunlight due to rebound from the sea surface or the road surface, and prevents the light from directly illuminating the wearer's eyes. To reduce glare.

  In particular, since the lower heel 53 is formed in a mountain shape whose center in the width direction rises upward, it is possible to avoid the proximal end facing the face of the lower heel 53 from coming into contact with the wearer's nose. Can do. And the central part which forms the mountain shape fits a nose, and shields the reflected sunlight which enters from the nose circumference effectively. For this reason, the situation where the reflected sunlight illuminates the wearer's eyes can be effectively avoided.

  Further, even in such a sun visor type double helmet 40, an upper collar 41 and a lower collar 53 are provided in advance in the mounting portion 42 to be worn on the head, so that it looks like a conventional sunscreen. However, there is nothing that can be carried separately from the original hat. For this reason, the situation which forgets, for example, a lower side rod is avoided.

  Further, even such a double hat 40 does not block the front of the field of view. For this reason, the field of vision in front of the wearing of the double hat 40 is not blocked by the double hat 40 of the present invention.

  In the above-described embodiment, a concave portion 23a that avoids contact with the nose is formed in the lower heel 23 of the so-called baseball cap-type composite cap 10 so that the lower heel of the so-called sun visor-type composite cap 40 is formed. Although the example in which 53 is formed in a mountain shape in which the center in the width direction swells upward is shown, the lower side ridge 23 of the so-called baseball cap type double hat 10 is formed in a mountain shape in which the center in the width direction swells upward. A recess 23 a that avoids contact with the nose may be formed on the lower heel 53 of the so-called sun visor type double hat 40.

  In the above-described embodiment, the hooks 21, 23, 41, 53 are used as locking means for locking the lower hooks 23, 53 superposed on the upper hooks 21, 41 to the upper hooks 21, 41. The male hooks 22 and 56 and the female hooks 25 and 57 that can be locked to the male hooks 22 and 56 attached at a predetermined interval in the front-rear direction are described in the center in the width direction. For example, it may be provided on both sides in the width direction. Further, this locking means is not limited to a hook, and may be other locking means such as a hook and loop fastener as long as the lower hooks 23 and 53 can be locked to the upper hooks 21 and 41. good.

  In the above-described embodiment, the numerical value is exemplified and explained in the main body 43 and the adjustment band 44 in the sun visor type double cap 40, but the mounting portion 42 having them is mounted on the head. As long as it is possible, the main body 43 and the adjustment band 44 are not limited to the numerical values exemplified in this specification, and are the mounting part 42 having the main body 43 and the adjustment band 44 that deviate from these numerical values. Also good.

  In the above-described embodiment, the sun visor type double cap 40 is exemplified by a plastic one. However, this may be one in which the plastic is covered with a cloth, which is made of cloth. May be.

  Furthermore, the double caps 10 and 40 of the present invention can be changed as appropriate without departing from the spirit of the invention. For example, various decorations and coloring are given to the outer surface of the mounting parts 12, 41 and the upper and lower surfaces of the upper and lower ridges 21, 23, 41, 53 to stimulate consumers' purchasing willingness, Information (characters and patterns) can be printed and embroidered.
