Description

  The present invention relates to footwear mainly for a lower body of a person that is suitable for underwater walking and can be used for enjoying fishing such as carp fishing.

  Footwear called “Wader” is useful for those who fish. A wader is convenient footwear when walking underwater. Many of these waders include a torso that covers the abdomen and buttocks of the angler and tights that cover both left and right feet. The trunk and the tights are continuous. A wader in which a sock part or a boot part for accommodating a fisherman's foot is continuously formed at the lower end of the tights part is also frequently used. The tights part is formed of, for example, closed cell foam chloroprene rubber, a waterproofed rubber member or the like, and the sock part is, for example, closed cell foam chloroprene rubber, a member in which a nylon resin or the like is bonded to the surface of the rubber member Etc. are formed. Of the tights, protective pads are sewn or embossed on portions corresponding to the knee, shin, and ankle. Such waders are disclosed in, for example, JP-A-9-187301, JP-A-10-234403, JP-A-11-158711, and the like.

  On the other hand, a boots type wader formed independently for each leg is also known. This wader covers the toes, shins, and thighs. In this wader, a portion below the knee is formed of, for example, Neoprene (registered trademark) sponge or the like. Gore-Tex (registered trademark) is used in the upper part from the knee. These waders are also provided with protective pads on the kneecap corresponding portions. Such a wader is disclosed in, for example, Japanese Patent Laid-Open Nos. 2001-353001 and 2002-17402.

  When the wind is strong, a strong frictional force or the like acts on the surface of the wader that is worn by a person in a river with a water stream. A wader formed of a stretchable soft material may be pulled by a strong wind or water flow and vibrate. In order to avoid such a situation, when the wader is made of a material that is relatively stretchable and relatively hard, there is a possibility that the free and light movement of the wearer may be hindered. In the conventional wader described above, avoiding such a situation is not expected.

JP-A-9-187301 JP 10-234403 A Japanese Patent Laid-Open No. 11-158711 JP 2001-353001 A JP 2002-17402 A

  An object of the present invention is to provide footwear that is less affected by water flow and strong wind during use and is less likely to hinder the free and light movement of the wearer.

The footwear according to the present invention is:
at least,
A torso that covers at least the buttocks of the wearer;
And tights that separately cover the left and right legs of the wearer,
The body part and the tights part are formed continuously from each other, and both are formed from a rubber or synthetic resin sheet having elasticity,
The front part and the rear part of the body part and the rear part of the tights part are formed from a soft sheet,
The side part of the trunk part and the front part and the outer side part of the tights part are formed from a sheet having higher hardness and density than the soft sheet.

  According to this footwear, since the rear part is formed of a soft sheet, the wearer can easily bend forward or walk in water or the like. Moreover, the side part of the trunk | drum and the side part of a tights part which are easy to vibrate by a water flow or a strong wind are strengthened. The torso may cover the wearer's abdomen and chest.

  The tights have a lower part of the tights lower than the part corresponding to the kneecap of the wearer and an upper part of the tights lower than the lower part of the tights. The sheet is preferably formed from a sheet having a higher hardness and density than each sheet in the front part of the upper part and the tights. This is because the front part of the lower part of the tights, which easily touches an obstacle, is effectively protected during walking.

  It is provided with a jersey layer laminated on both front and back surfaces of the body part and the tights part, and in the vicinity of the upper end of the body part, a sheet exposed surface part on which the jersey layer is not laminated is formed on the back surface. preferable. This is because the sheet exposed surface portion (the surface on which the rubber or the synthetic resin is exposed) is in close contact with the circumference of the wearer's torso, so that effective slip prevention is achieved.

  From the viewpoint of improving the anti-slip effect, it is preferable that irregularities be formed on the surface of the sheet that becomes the surface of the sheet exposed surface portion.

  The footwear according to the present invention is less affected by water flow and strong wind during use, and inhibits wearer's free and light movement.

FIG. 1 is a perspective view of an embodiment of footwear according to the present invention as viewed obliquely from the front. FIG. 2 is a perspective view of the footwear of FIG. FIG. 3 is a front view of the footwear of FIG. 4 is a rear view of the footwear of FIG. FIG. 5 is a view showing a part of the back surface of the front portion of the footwear shown in FIG.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

The footwear 1 shown in FIGS. 1 to 4 is a wader used by anglers and the like. The wader 1 is convenient footwear when walking underwater. The wader 1 is formed from a rubber or synthetic resin sheet having elasticity. The entire wader 1 of this embodiment is basically formed of a sheet of closed cell foam using polychloroprene as a base rubber. A jersey layer is laminated on almost the entire front and back surfaces of the chloroprene rubber sheet (internal and external surfaces of the wader 1). For the jersey layer, nylon fiber, polyester fiber, a blend of nylon fiber and polyurethane fiber, or the like is employed. The jersey layer is not limited to such materials. The base material of the sheet is not limited to polychloroprene rubber, and for example, SBR (styrene / butadiene rubber), SCR (styrene / chloroprene rubber), SCM (chlorosulfonated polyethylene) and the like can be employed.

  The wader 1 has a trunk 2 that covers the wearer's abdomen and buttocks, and a tights 3 that separately covers the left and right legs of the wearer. “Cover the abdomen and the buttocks” means to cover the entire circumference of the front and rear and the left and right sides of the abdomen, and the entire circumference of the front and rear and the left and right sides of the buttocks. The body portion 2 is formed with an open portion 4 that is torn downward from the upper end of the front portion thereof. The opening 4 can be opened and closed by attaching a fastener 5. Although not shown, a shoulder strap for hanging from the shoulder of the wearer may be provided on the upper end of the trunk 2. The vertical length of the body 2 is not limited. The trunk | drum 2 may be the length which covers only a buttocks, for example, and the length which covers a buttocks, an abdomen, and a chest.

  The tights 3 is divided into a left leg 6 and a right leg 7. The left leg 6 has a lower left leg 6L below the wearer's kneecap corresponding part and an upper left leg 6U above the left leg lower 6L. The right leg portion 7 has a lower right leg portion 7L below the wearer's kneecap corresponding portion and an upper right leg portion 7U above the right leg lower portion 7L. The left leg lower part 6L and the right leg lower part 7L are collectively referred to as a tights lower part 3L. The left leg upper part 6U and the right leg upper part 7U are collectively referred to as a tights upper part 3U.

  An open portion 8 is formed which is cut upward from the lower ends of the left and right leg portions 6 and 7. The opening 8 can be opened and closed by attaching a fastener 9. A belt 10 is provided at the lower end of each of the left and right leg portions 6 and 7 for fastening the periphery of the lower end to the wearer's ankle. Although not shown, a sock part or a boot part may be connected to the lower ends of the left and right leg parts 6 and 7.

  As shown in FIG. 5, in the vicinity of the upper end of the body portion 2, a sheet exposed surface portion 12 on which the jersey layer 11 is not laminated is formed on the back surface thereof. FIG. 5 shows a part of the back surface of the front portion of the wader 1. The surface of the sheet exposed surface portion 12 is a surface where the surface of the chloroprene rubber sheet 13 is exposed. Fine irregularities 14 are formed on the surface of the chloroprene rubber sheet 13 by embossing. The unevenness 14 is obtained by transferring the unevenness formed on the inner surface of a mold for molding the chloroprene rubber sheet 13. The chloroprene rubber sheet 13 is obtained by slicing a thick parent sheet molded by a mold into a plurality of thin sheets. The sheet | seat 13 which has the said unevenness | corrugation 14 is a sheet | seat which has the surface which was in contact with the inner surface which has the unevenness | corrugation of a metal mold | die among the said several thin sheets. The surface of the chloroprene rubber sheet 13 has a larger coefficient of friction than the surface of the jersey layer 11. The surface of the chloroprene rubber sheet 13 on which fine irregularities 14 are formed has a higher friction coefficient. Since this sheet | seat exposure surface part 12 closely_contact | adheres to a circumference | surroundings of a wearer's trunk | drum, it is suppressed that the upper part of the wader 1 slips down from a wearer's body.

  As shown in FIG. 5, a cover sheet portion 15 is provided inside the fastener 5 in the opening portion 4 of the trunk portion 2. The cover sheet portion 15 is for preventing the fastener 5 from coming into contact with the wearer's body. The cover sheet portion 15 covers the entire length of the fastener 5 from the back side (the inside of the wader 1). The back surface (the surface facing the wearer's body) of the cover sheet portion 15 is also a sheet exposed surface portion 16 on which the jersey layer 11 is not laminated. Fine irregularities 17 are also formed on the surface of the sheet exposed surface portion 16 by embossing. When the sheet exposed surface portion 16 is in close contact with the wearer's abdomen, the upper portion of the wader 1 is suppressed from sliding down from the wearer's body.

  As shown in FIGS. 1 to 4, the wader 1 is formed by sewing a plurality of chloroprene rubber sheet pieces having different shapes. The plurality of chloroprene rubber sheet pieces are arranged symmetrically with respect to the longitudinal center line CL of the wader 1. The chloroprene rubber sheet piece arranged on the center line CL has a symmetrical shape.

  Hereinafter, the arrangement of a chloroprene rubber sheet piece (hereinafter also simply referred to as a sheet piece) will be described with reference to FIGS. 3 and 4. Depending on the part of the wader 1, as the sheet piece of the part, the soft sheet S, the hard sheet H, or the super hard sheet HH whose hardness and density are further increased than the hard sheet can be adopted. In FIG. 3 and FIG. 4, for easy understanding, the part of the super hard sheet HH is indicated by a check, the part of the hard sheet H is indicated by hatching of only parallel lines, and the part of the soft sheet S is indicated by plain color. Has been. Compared to the soft sheet S, the hard sheet H is tough but has little elongation and is hard. The super hard sheet HH is further tough, has little elongation and is hard.

  The soft sheet S is used because of the first sheet piece 21S near the upper end of the body part 2, the second sheet piece 22S from the front part of the body part 2 to the inner front part of the tights upper part 3U, A third sheet piece 23S from the rear part to the rear part of the tights upper part 3U, a fourth sheet piece 24S on the left and right sides inside the tights upper part 3U, and a fifth sheet piece 25S on the rear part of the tights lower part 3L. The hard sheet H is used for the sixth sheet piece 26H from the left and right side parts of the body part 2 to the side part and the front part of the tights upper part 3U, and the seventh sheet piece on the right and left side parts outside the tights lower part 3L. 27H and the eighth sheet piece 28H on the left and right sides inside the tights lower part 3L. The super hard sheet HH is used in the ninth sheet piece 29HH at the front of the tights lower part 3L.

The soft sheet S preferably has a density of 0.15 g / cm ³ or less, and preferably has an HS C-type hardness (Asker C-type hardness) of 1 or more and 3 or less. As the hard sheet H, the density is preferably more than 0.15 g / cm ³ and 0.19 g / cm ³ or less, and the HSC hardness is preferably 4 or more and 6 or less. The super-hard sheet HH preferably has a density exceeding 0.19 g / cm ³ and not more than 0.31 g / cm ³ , and its HSC hardness is preferably not less than 8 and not more than 12. The density of the sheet can be changed by adjusting the additive composition of the chloroprene rubber and the expansion ratio.

  It is when the wearer moves underwater that the wader 1 receives a large amount of water resistance. At this time, water, suspended solids, aquatic plants, sand, gravel, etc. collide with the front part of the tights 3 of the wader 1. Further, the side portion of the tights 3 is rubbed with the water and the like passing therethrough and is vibrated with a flutter. At a deep water depth, the trunk 2 is in a similar situation. For this reason, the hard sheet | seat H is used as each 6th, 7th, 8th sheet piece 26H, 27H, and 28H of the front part and side part of the tights part 3, and the side part of a trunk | drum. In particular, the front part of the lower part 3L of the tights is likely to hit pebbles and rocks. Therefore, the super hard sheet HH is used as the ninth sheet piece 29H in the front part of the tights lower part 3L.

  On the other hand, the rear part of the wader 1 is less affected by water flow, suspended matter and the like than the front part and the side part. Furthermore, the rear part of the wader 1 is often extended with the wearer's forward bending or sitting. Therefore, the soft sheet S is used for the third sheet piece 23S from the rear part of the body part 2 to the rear part of the upper part 3U of the tights and the fifth sheet piece 25S at the rear part of the lower part 3L of the tights. The left and right side portions inside the tights upper portion 3U correspond to the upper portion of the wearer's inner crotch. This part is less affected by water flow and suspended matter. On the other hand, this part is frequently expanded and contracted as the wearer walks. Therefore, the soft sheet S is also used for the fourth sheet piece 24S of this part. The front part of the body part 2 has few opportunities to be buried in water. Moreover, the structure of the front part of the trunk | drum 2 should be considered with the structure of the rear part of the trunk | drum 2, so that the constant movement of a wearer's upper body may not be inhibited. The inner front part of the upper part 3U of the tights is also frequently expanded and contracted with the wearer's walk. For the above reason, the soft sheet S is used for the second sheet piece 22S from the front part of the body part 2 to the inner front part of the upper part 3U of the tights. In the vicinity of the upper end of the body 2, the influence of water flow, suspended matter, etc. is extremely small. This site is preferably in close contact with the wearer's torso. For this reason, the soft sheet S is also used as the first sheet piece 21S of this part. Further, as described above, the sheet exposed surface portion 12 is formed in this portion.

  The arrangement of the soft sheet S, the hard sheet H, and the super hard sheet HH is not limited to the above. From the viewpoint of fitting to the wearer's body and the viewpoint of easy attachment / detachment, it is preferable that the soft sheet S is used on at least a part of the entire circumference of both the body 2 and the legs 6 and 7. . Moreover, it is preferable that the flexible sheet | seat S is used also for the rear part of the trunk | drum 2 and the back part of the tights part 3 from a viewpoint of a wearer's easy walk, forward bending, and seating. From the viewpoint of preventing harmful effects caused by water flow, suspended matter, etc., it is preferable that the side portion of the trunk portion 2 and the front portion and the outer side portion of the tights portion 3 are formed from the hard sheet H.

  The second sheet piece 22S made of the soft sheet S is formed in an elliptical shape or a water droplet shape in the upside down direction from the front portion of the body portion 2 to the inner front portion of the tights upper portion 3U. This is intended not only to improve the design of the wader 1 but also to improve the comfort for the wearer by providing flexibility to the abdomen.

  Depending on each sheet piece described above, the stretch rate of the jersey layer 11 may be different. For example, a first jersey layer having a large expansion / contraction ratio in any axial direction of XY orthogonal to each other, a second jersey layer having a large expansion / contraction ratio only in any one XY direction of XY and a small expansion / contraction ratio in the other axial direction, and , XY are selected from the third jersey layer having a small expansion and contraction rate in any axial direction of XY. For example, a first jersey layer having a large expansion / contraction rate may be laminated on the entire inner surface (back surface) of the wader 1. For example, on the outer surface of the wader 1, a first jersey layer is laminated on the soft sheet S, a second jersey layer is laminated on the hard sheet H, and a third jersey layer is laminated on the super-hard sheet HH. May be. According to such a configuration, the flexibility of the soft sheet S is not impaired, and the toughness of the hard sheet H is not impaired. The second jersey layer is preferably laminated so that the direction in which the expansion / contraction ratio is large is the vertical (up / down) direction and the direction in which the expansion / contraction ratio is small is the horizontal direction. This is because the suppression of the vibration of the wader 1 due to the water flow and the ease of bending and stretching of the wearer's body are taken into consideration.

  A wader is exemplified as the embodiment described above. However, the application of the present invention is not limited to a wader. For example, the present invention can be applied to ski wear, ice skating wear, and the like.

  The footwear according to the present invention can be worn in the air as well as suitable for walking underwater. In particular, it is suitable for fishing performed in water such as rivers and ponds.
