Description

[Technical field]

[0001] The present invention relates to a hat that fits the wearer's head and is difficult to remove even when the brim or visor is exposed to wind. [Background technology]

[0002] Although some hats have no brims, the mainstream are hats that have a brim around the entire circumference ("hats"), hats with brims or baseball caps (caps), sun visors, which are equivalent to caps without a crown, and which tend to come off easily when the brim is caught by the wind in strong winds or when exercising (hereinafter referred to as "hats, etc.").

[0003] 2. Description of the Related Art When working outdoors or playing sports, various methods and means are used to prevent hats from falling off due to the wind catching on the brim or brim of the hat. Other methods that have been devised include using chin straps or clipping the hat to the hair, but among these, many methods that have been devised to make it difficult to remove a hat without using strings or pins involve increasing the friction between the sliding part of the hat and the surface of the head.

[0004] Hats that are equipped with hook-and-loop fasteners or adjusters for adjusting the circumference of the head are widely available, and tighten the head circumference of the wearer to increase friction and make the hat less likely to fall off. Such adjusters are often used in cap-type hats that have a brim at the front of the head. However, if the fabric is not stretchy, the hat will loosen over time and become more likely to fall off. Also, while the hat will be less likely to fall off if it is tightened too much, it will cause pain and discomfort to the wearer if it is too tight.

[0005] Hats worn by children in elementary school physical education classes typically have elastic bands or band-like or belt-like elastic members with rubber woven into them inserted around the head, but these are not often used in hats worn by adults because the crowns tend to wrinkle. A hat (Patent Document 2) has been devised in which the slider part is made of elastic fabric and molded slightly smaller than the circumference of the head part, making it possible for the hat to fit the head and to be difficult to remove; hats in which the crown and slider part of a cap are made of elastic fabric and molded slightly smaller than the circumference of the head part, making it possible for the hat to fit the head and to be difficult to remove, are widely available. These hats have in common that when the slider portion is made from stretchy fabric, the slider portion stretches when the hat is worn, generating an almost uniform tensile force within the surface of the slider around the entire head circumference.

[0006] Generally, the sliding parts are often made of ordinary fabric or natural or synthetic leather for the purpose of absorbing sweat, but some are made to be breathable (Patent Documents 1 and 4) or have features to enhance the anti-slip effect (Patent Document 3). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 9-137315 [Patent Document 2] JP 2003-129322 A [Patent Document 3] JP 2013-7144 A [Patent Document 4] Utility Model Registration No. 3183608 Summary of the Invention [Problem to be solved by the invention]

[0008] The problem to be solved is that in order for the hat to fit the head and not come off easily, it must be tightly fastened all around the head. In addition, regarding hats that tend to come off when the brim catches the wind, many hats currently on the market have different levels of ease or difficulty in coming off at the front part that comes into contact with the wearer's forehead, and the sides and back of the head that come into contact with the hair. However, because the entire circumference of the head is constructed in the same way, the entire circumference of the head must be tightened equally tightly. [Means for solving the problem]

[0009] The most important feature of the present invention is that an elastic member having a predetermined thickness is attached to the sliding portion of the hat.

[0010] The elastic member is attached to the entire area of ​​the inner periphery of the hat or the like where the slider is arranged, or the elastic member of a predetermined thickness is attached to one or more partial areas of that area to form the hat or the like.

[0011] The elastic member is configured so that when the hat or the like is worn on the human head, the elastic member is compressed in the thickness direction. "Thickness direction" means the direction perpendicular to the surface of the human body, or the direction perpendicular to the contact surface between the human body and a cap, or the direction perpendicular to the curved surface when the sliding position is viewed as a band-shaped curved surface.

[0012] The elastic member compressed in the thickness direction generates a restoring force according to Hooke's law, generating a pressing force perpendicular to the surface of the human body. Depending on the friction coefficient at each point on the contact surface between the elastic member and the human body surface, a frictional force proportional to the pressing force generated at that point is generated. The greater this frictional force, the harder it is to remove the hat, etc.

[0013] As in the prior art, when the sliding portion is made of elastic fabric, band, etc., the stress generated in the fabric, band, etc. is tensile, and the direction of the tensile and restoring forces is in the in-plane direction of the fabric, band, etc. and in the direction around the head. In other words, the present invention is the same as the prior art in that it uses an elastic body, but the positive / negative and direction of the stress generated in the elastic body are different.

[0014] Also, like the prior art, it increases the friction between the sliding portion of the hat or the like and the surface of the head, making it difficult for the hat or the like to come off. However, the present invention does not aim to make the slider itself of a specific material or shape, but rather to attach an elastic member that is separate from the slider to the slider, and therefore the area to which the elastic member is attached is not limited to the area where the slider is located.

[0015] It is also possible to attach an elastic member that is large enough to cover an area slightly larger than the slider. Conversely, it is also possible to attach an elastic member that covers a necessary area smaller than the slider, or to place multiple elastic members in the area where the slider should be provided. Therefore, assuming the parts and ranges where slippage would occur with a normal hat, the band-like area around the head inside the hat was represented as the "equivalent position of slippage."

[0016] The elastic member is made of chloroprene rubber, which has a large coefficient of friction. Rubber-based materials have a smaller modulus of longitudinal elasticity and a larger coefficient of friction than regular cloth fabrics, making them more elastic than cloth fabrics and generating greater friction on the contact surface with the forehead and hair. For example, chloroprene rubber containing air bubbles therein, which is used in wet suit fabric, is easily available and is suitable as a material for the elastic member. Effect of the Invention

[0017] In the elastic member of the present invention, a restoring force is generated mainly by compression in the thickness direction of the elastic fabric, so by making the thickness of the elastic fabric different or varying, the surface pressure at the contact points between the sliding part and the elastic fabric and the wearer's forehead, scalp or hair can be made different at each point of the sliding part, which has the advantage that surface pressure and frictional force of an appropriate magnitude can be generated depending on the type of hat and the location of the sliding part.

[0018] The elastic member made of rubber-based material such as wetsuit fabric feels good against the skin and has a higher friction coefficient than the conventional cloth material used for hat linings. It has the advantage that it is easy to achieve an appropriate frictional force distribution by designing the size, shape, and arrangement of the elastic member.

[0019] By designing the size, shape and arrangement of the elastic members, it is possible to ensure appropriate breathability. The gaps between multiple elastic members and the thin areas of the elastic members can be designed to be highly breathable.

[0020] In the case of thin stretch fabrics that utilize tensile force as seen in the prior art, the elastic body such as rubber bands stretches over time and eventually loses elasticity. In contrast, the elastic member of the present invention, which is compressed in the thickness direction, is also likely to deform and lose elasticity over time, but since a relatively thick member is used, there is an advantage that the rate of decrease in the resistance to slipping off is smaller than that of members that utilize tensile force, even after a long period of time.

[0021] The present invention has an advantage in that it can be applied to various headwear and equipment such as caps, hats, sun visors, helmets, and headlamps. [Brief description of the drawings]

[Figure 4] FIG. 1 is a bottom view showing one embodiment of the hat of the present invention (Example 2). [Diagram 5] FIG. 1 is a perspective view including a bottom surface showing one embodiment of a hat of the present invention (Embodiment 3). [Figure 6]FIG. 4 is a cross-sectional perspective view showing one embodiment of the hat of the present invention (Embodiment 4). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, an embodiment of the present invention will be described with reference to FIG.

[0024] 1 is a perspective view of a hat in which a thick, fabric-like elastic member 5 is attached to the slider 3 at a position where it contacts the wearer's forehead. The elastic member 5 is shown as being attached mainly to the slider 3. The elastic member 5 is illustrated as a thick rectangular piece of fabric that is wider than the slider 3 and is arranged symmetrically on the left and right sides of the hat. The part of the slider 3 to which the elastic member 5 is not attached is exposed on the inside, just like a normal hat.

[0025] The elastic member 5 is made of a material that has a smaller modulus of longitudinal elasticity and a larger coefficient of friction than ordinary cloth fabrics, that is, an elastic material that is more stretchable than cloth fabrics and generates a larger frictional force on the contact surface with the forehead or hair. Specifically, for example, wetsuit fabric, which is a chloroprene rubber fabric containing air bubbles inside, can be used as the elastic member. Therefore, in Fig. 1, a wetsuit fabric cut to a size large enough to cover the forehead of the hat wearer is attached to the slider 3 as the elastic member 5.

[0026] The elastic member 5 utilizes the restoring force generated by the compression deformation in the thickness direction, so it needs to be thick enough to exert a sufficient restoring force, but its shape is not important. On the other hand, if it is a fabric-like material, it can be easily cut and shaped, but it needs to be thicker than the cloth material of an ordinary hat. If the elastic member 5 is too thick, it becomes difficult to put on and take off the hat, so in order to make it easy to put on and take off the hat and to generate sufficient compression and recovery force, the thickness of the elastic member 5 is assumed to be 3 mm to 8 mm. Therefore, FIG. 1 shows a wetsuit fabric cut to a thickness of 5 mm.

[0027] However, the thickness of the elastic member does not need to be constant, and it is possible to vary the thickness partially, for example by making only a specific location thicker if it is desired to increase the frictional force at that location. Also, the cross-sectional shape, i.e., the thickness distribution, may be continuously changed in both the vertical and horizontal directions depending on the head shape and the presence or absence of hair. It is also possible to use an elastic member having a two-dimensional thickness distribution, in which the thickness varies at different points on the elastic member.

[0028] The elastic member 5 may be arranged so as to cover the entire area of ​​the inner circumference of the hat, etc. that corresponds to the slider, but this is not necessary. In other words, when the slider of a normal hat is viewed as a belt-like curved surface, the elastic member 5 does not need to have exactly the same dimensions as the belt-like curved surface. Furthermore, it is not necessary for the size to cover the entire slider-equivalent position, and it is sufficient to place it in a position that can generate frictional force to prevent the hat or the like from coming off, and as shown in Figure 1, there may be parts where the slider 3 without the elastic member 5 attached is exposed on the surface.

[0029] In addition, the elastic member does not need to be a single member, and multiple elastic members can be combined and placed in the required portion of the sliding equivalent position. In addition, when multiple elastic members are used, the size and shape of each elastic member do not need to be the same.

[0030] The elastic member can be attached to the inner circumference of the slider or hat by means of adhesive, sewing with thread, or a combination of these means. In the case of encounters, The elastic member is compressed by pressing it down with the adhesive thread. As a result, the helmet can be prevented from coming into contact with the head of the person wearing the helmet. The inner surface shape of the elastic member may be changed to have projections and recesses. EXAMPLES

[0031] Fig. 2 is a bottom view of one embodiment of the present invention, and Fig. 3 is a cross-sectional view of the right side of Fig. 2. Although omitted in other figures, Fig. 2 shows an adjuster 6 for adjusting the head circumference length.

[0032] In this embodiment, a wet suit fabric measuring approximately 50 mm in length, 300 mm in width and 5 mm in thickness is adhered to the front half of the inner periphery of the head circumference of the inner surface of the hat as an elastic member 51. The vertical length of the elastic member 51 is slightly longer (higher) than that of the slider 3.

[0033] The reason why the elastic member is provided on half of the inner circumference of the head on the inside of the hat is that if the elastic member is provided on the entire inner circumference of the head, it will be difficult to put on the hat. The reason for placing the elastic member 51 in the front half of the inner circumference of the head is that it is intended to come into contact with the forehead of the wearer. In order to prevent the hat from coming off due to wind hitting the brim 2, it is effective to increase the frictional force at the part of the hat that comes into contact with the wearer's forehead. EXAMPLES

[0034] Fig. 4 is a bottom perspective view of one embodiment of the present invention. Elastic member 521 that comes into contact with the wearer's forehead and elastic members 522 and 523 that come into contact with the sides of the head are separate members. Elastic members 522 and 523 are provided at symmetrical positions on the left and right of the hat, and are shown in Fig. 4 as being thinner than elastic member 521.

[0035] The elastic member 521 at the forehead portion, which is thought to be particularly effective in making the hat difficult to remove, is made of a slightly thicker material. Furthermore, there are areas between the elastic member 523 and the elastic members 523, 524 that come into slight contact with the sides of the head where no elastic member is attached, and the presence of these gaps improves breathability.

[0036] As in this embodiment, a plurality of elastic members can be used and arranged at positions equivalent to sliding. Possible And those The thickness does not need to be the same. The spaces between the multiple elastic members can be designed to ensure ventilation or to facilitate folding of the hat. EXAMPLES

[0037] FIG. 5 is substantially the same as the second embodiment, but the elastic members 521 to 523 which are separate in the second embodiment are integrated into one. The elastic members 521 and 522 in the second embodiment correspond to the elastic member portions 531 and 533 in the third embodiment, but are connected and integrated by the thinner elastic member portion 532. All the elastic members are similarly provided at symmetrical positions on the left and right sides of the hat.

[0038] This embodiment shows that it is possible to make the elastic member have different thicknesses at different portions. Furthermore, the thickness does not have to change stepwise, but may change continuously. EXAMPLES

[0039] FIG. 6 shows in cross section the elastic member 5 of FIG. 1 as an elastic member 541 whose thickness varies in the vertical direction.

[0040] The elastic member 541 has a mountain-shaped uneven surface on the surface that comes into contact with the wearer's forehead. As can be seen in the longitudinal section of the elastic member 541, the elastic member is designed to be thinner at the bottom end of the hat to make it easier to wear. This mountain-shaped uneven surface can be designed to help with ventilation and sweat management at the part that comes into contact with the wearer's forehead. The shape of the surface of the elastic member that comes into contact with the wearer's head is not limited to the shape shown in the figure, and any three-dimensional shape can be designed.

[0041] At the portions of the elastic member where the thickness is large, the elastic body is compressed to a greater extent, resulting in a larger frictional force, but the cross-sectional shape of the elastic member is not limited to that of this embodiment. As in this embodiment, by using an elastic member that not only changes its thickness vertically but also changes its thickness horizontally or has a design with slits or grooves, it is possible to adjust the frictional force in each part and to adjust the breathability and sweat discharge.

[0042] It is easy to custom-make a member with a three-dimensional shape such as that shown in the figure for the elastic member 541, but when using wetsuit fabric, for example, even if the original fabric is similar to a thick flat plate, a recess can be formed in that part by pressing it down with an adhesive thread. By making horizontal cuts in the wetsuit fabric and pressing one side of the cut with a bonding thread, it is possible to easily form a shape similar to the corrugated cross section shown in the figure. Also, when pressing the wetsuit fabric with the bonding thread, if the bonding is performed intermittently rather than continuously, a horizontally uneven shape can also be created.
