Description

[Technical Field]

[0001] The present invention relates to a raincoat that can be worn with shoes on. [Background technology]

[0002] Rain gear, also known as raincoats, rain jackets, and the like, is made of waterproof sheet material and protects the wearer's head, torso, legs, etc. from getting wet in the rain, but is usually not designed to cover the wearer's shoes as well. Even with pants-type raincoats, not only do the shoes get wet, but rain can also seep into the inside of the pants from the bottom, wetting the clothing. Especially during heavy rainfall such as storms, roads can flood and shoes can get soaked. The same is true on snowy roads where shoes can get buried.

[0003] Patent Document 1 discloses rain gear in which a trouser-like cover and a shoe-like cover connected to the bottom are molded together from a plastic film. Patent Document 2 discloses waterproof pantyhose that are worn over clothing and shoes. Patent Document 3 describes rain pants that have a pair of bag-like lower leg sections extending from the waist and have a sheet-like or point-like reinforcing material on the outer surface of the sole at the tip of the lower leg sections. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 50-11729 [Patent Document 2] Japanese Utility Model Application Publication No. 5-89404 [Patent Document 3] Patent No. 6256731 Summary of the Invention [Problem to be solved by the invention]

[0005] The rain gear or waterproof pantyhose described in Patent Documents 1 and 2 are worn over shoes, but since there is no reinforcement in the sole of the foot, there is a high possibility that they will tear while walking.

[0006] Although the rain pants in Patent Document 3 have planar or dot-like reinforcing materials formed on the outer surface of the sole, reaction forces from the road while walking and shear forces when kicking backwards are transmitted directly to the sole of the rain pants via the reinforcing materials, so there is still a high possibility of the sole tearing. Also, because the sole of the rain pants is not fixed to the wearer's shoe at all, when the wearer lifts their foot while walking, the sole of the rain pants does not follow the rising sole of the shoe but moves away, and when the wearer puts their foot down, the sole of the shoe and the sole of the rain pants collide and come into contact again, making it very difficult to walk.

[0007] To provide a raincoat that can be worn with shoes on, is free from the risk of being torn while walking, and is easy to walk in. [Means for solving the problem]

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings as examples, in which the same or similar components are designated by the same reference numerals in the various embodiments.

[0013] The raincoat of the present invention is intended to be worn over shoes. However, it can also be worn without shoes. In this specification, the term "shoes" is not limited to those that are necessarily called "shoes," but is used in a broad sense to include all footwear worn when walking outdoors.

[0014] Fig. 1 is a schematic front view showing an example of a first embodiment of the raincoat according to the present invention. Fig. 2 is a schematic side view of the raincoat of Fig. 1. The raincoat 1 has a bottom portion 20 worn on the lower body and an top portion 30 worn on the upper body, which are integrally connected in a so-called connected configuration. The raincoat 1 also has a hood portion 40 continuing above the top portion 30, and a slipper portion 10 joined to the lower end of the bottom portion 20. The term "bottom portion" here does not mean underwear, but rather refers to clothing worn on the lower body.

[0015] The lower garment portion 20 comprises a waist portion 21 and a pair of leg portions 22 extending from the crotch portion to the lower opening. The leg portions 22 are long enough that their lowest ends reach almost the wearer's heels. The upper garment portion 30 comprises a torso portion 31 extending upward from the waist portion 21 of the lower garment portion 20, and a pair of arm portions 32. In the illustrated example, an elastic member 35 made of an elastic material such as a rubber cord is provided at a position roughly corresponding to the boundary between the lower garment portion 20 and the upper garment portion 30, but this is not essential. A zipper 33 is provided at the center of the front, extending vertically from the upper end of the torso portion 31 to the middle of the waist portion 21. The zipper 33 is opened and closed when putting on and taking off the raincoat 1. It is preferable that an elastic member 34 is also provided at the edge of the tip opening of each arm portion 32.

[0016] The hood portion 40, which extends upward from the torso portion 31 of the upper garment portion 30, has a face opening 42 that exposes the face at the front. A stretchable member 43 is provided around the face opening 42, but this is not essential.

[0017] The lower garment portion 20, the upper garment portion 30, and the hood portion 40 are formed from thin sheets of waterproof material. For example, nylon sheets, which are widely used in general raincoats, are preferred. The waterproof material is not particularly limited as long as it is suitable for a raincoat. Although the lower garment portion 20, the upper garment portion 30, and the hood portion 40 are integrated, this does not mean that the entire raincoat is made of a seamless sheet. In manufacturing, the raincoat 1 may be formed by joining multiple component sheets while ensuring waterproofness, as necessary. This also applies to each of the lower garment portion 20, the upper garment portion 30, and the hood portion 40. For waterproof joining, for example, waterproof adhesives, welding, sewing, waterproof tape, etc. are used.

[0018] Furthermore, a slipper part 10 is joined to the lower opening of the leg part 22 of the lower garment part 20. The slipper part 10 has a lower sole member 11 and an upper member 12. This has the same structure as ordinary slippers. As the slipper part 10 does not have a part that covers the heel, it is easy for the wearer to insert their foot while wearing shoes.

[0019] However, the entire slipper portion 10 of the present invention is made of a waterproof material. The lower sole member 11 and the upper member 12 have no holes or slits, and the connection between these members is also watertight. Therefore, water cannot enter or exit through the main body of the slipper portion 10. Examples of such waterproof materials include polyvinyl chloride and ethylene vinyl acetate. While the lower sole member 11 and the upper member 12 are shown as separate members in FIG. 1, they may also be integrally molded. The slipper portion 10 is preferably lightweight and flexible, but must also be strong enough to withstand walking outdoors in bad weather. In particular, the lower sole member 11 is made of a material and thick enough to ensure strength comparable to that of a regular shoe sole. Preferably, the underside of the lower sole member 11 is provided with anti-slip embossments.

[0020] Referring to the schematic side view of FIG. 2, the edge 22a of the lowermost leg portion 22 of the lower garment portion 20 is overlapped and joined to the heel side of the side surface 11b of the lower sole member 11 of the slipper portion 10, forming a joint 51. Furthermore, the edge 22a of the leg portion 22 is overlapped and joined to the edge 12a of the upper member 12, forming a joint 52. Preferably, each of the joints 51 and 52 is formed over the entire overlapping portion of the two joined members. The joints 51 and 52 are continuous. In this way, the edge 22a of the leg portion 22 and the slipper portion 10 are joined without gaps, ensuring waterproofness. The joints 51 and 52 can be formed, for example, by gluing or welding. Waterproof tape may also be used. For example, a waterproof adhesive is used for adhesion. For example, high-frequency welding is used to join the nylon leg portion 22 and the polyvinyl chloride slipper portion 10.

[0021] When the lower garment portion 20 and the slipper portion 10 are joined together without any gaps, the lower opening of the leg portion 22 is sealed from the outside of the raincoat 1 by the slipper portion 10. In other words, the slipper portion 10 acts as a sealing lid that closes the lower opening of the leg portion 22. Therefore, by wearing the raincoat 1 with shoes on, it is possible to prevent the shoes and trouser cuffs from getting wet even when walking on flooded or snowy roads. The width of the leg portion 22 of the lower garment portion 20, which is cylindrical when worn, is preferably set to a spacious dimension so that the legs can be easily inserted while wearing shoes. The slipper portion 10 is also preferably set to a larger dimension than a typical slipper, assuming that it will be inserted while wearing shoes.

[0022] In the raincoat 1, the edge 22a of the leg portion 22 is joined to the upper member 12 of the slipper portion 10 and the side surface 11b of the lower sole member 11, but is not joined to the upper surface of the lower sole member 11, so that the reaction force and shear force that the lower surface of the lower sole member 11 receives when walking are not directly transmitted to the sheet material that makes up the leg portion 22. This prevents the sheet material of the leg portion 22 from being torn by the force that the slipper portion 10 receives when walking. This prevents water from entering due to damage to the leg portion 22. In contrast, the reinforcing material of the rain pants in Patent Document 3 is bonded to the outer surface of the sole of the sheet material that makes up the rain pants, so the sole of the rain pants is easily torn by the force that the reinforcing material receives when walking, and cracks may occur in the sole or its surrounding area, allowing water to enter.

[0023] Furthermore, in the raincoat 1 of the present invention, the slipper part 10 has an instep member 12, which limits the range of upward and lateral movement of the wearer's shoe or foot inserted into the instep member 12, stabilizing the position of the shoe or foot and making it easier to walk. In other words, the presence of the slipper part 10 improves walking comfort on flooded or snowy roads. In contrast, the rain pants of Patent Document 3 only have planar or dot-shaped reinforcing material formed on the outer surface of the sole of the sheet material, which means that the reinforcing material easily separates from the wearer's shoes, making it difficult to walk.

[0024] In the illustrated example, a plurality of length adjusters are attached to the front of the torso portion 31 to adjust the raincoat 1 to the wearer's physique. In the illustrated example, vertical length adjusters 36a, 36b are arranged in pairs on either side of the center of the front. In the case of a hook-and-loop fastener, for example, adjuster 36a is the fastening part, and adjuster 36b is the fastened part with a predetermined length. For example, when it is desired to shorten the vertical length, the back surface of adjuster 36a is placed over the front surface of adjuster 36b and fastened to the front surface of adjuster 36b in a state where pleats (wrinkles or tucks) are gathered to shorten the vertical length of the torso portion 31. Similarly, for left-right length adjusters 37a, 37b, adjuster 37a is the fastening part of the hook-and-loop fastener, and adjuster 37b is the fastened part with a predetermined length. When it is desired to shorten the length in the left-right direction, the adjuster 37a is folded so as to shorten the length of the body 31 in the left-right direction, and then the back surface of the adjuster 37a is placed on the front surface of the adjuster 37b and locked to the adjuster 37b. The adjustment range is determined by the lengths of the locked parts 36b and 37b.

[0025] Similar length adjusters 26a, 26b are also provided on the front of the leg portion 22. This allows the vertical length of the lower garment portion 20 to be adjusted.

[0026] An example of how to put on the raincoat 1 is as follows. The wearer first opens the zipper 33 of the raincoat 1, puts their left and right legs into the leg sections 21 of the lower garment section 20 while still wearing their shoes, and inserts the front half of their shoes into the instep member 12 of the slippers 10. Next, they put their left and right arms into the arm sections 32, put on the hood 40, and close the zipper 33. The length of the raincoat 1 in the vertical and horizontal directions can be adjusted as needed. Of course, the raincoat 1 can also be put on without shoes.

[0027] FIG. 3(a) is a schematic front view showing an example of a second embodiment of the raincoat according to the present invention. FIG. 3(b) is a schematic side view of the raincoat of (a). The raincoat 2 is composed only of the lower garment part 20 and slipper part 10 of the first embodiment described above. These components are the same as those of the first embodiment described above, so a description thereof will be omitted. The raincoat 2 can be put on by simply putting it on like regular trousers. As with the first embodiment, shoes can be worn with or without shoes. An elastic member 35 is provided around the periphery of the upper opening of the waist part 21.

[0028] 4(a) to 4(d) are schematic perspective views showing examples of modified forms of the slipper part 10. The slipper part 10 of FIG. 4(a) has a lower sole member 11 and an upper member 12, and the upper member 12 is dome-shaped with a closed toe side. The upper member 12 entirely covers the upper half of the toe side of the upper surface 11a of the lower sole member 11. While the basic shape is the same as that of ordinary slippers, the dome-shaped space formed by the upper member 12 of the slipper part 10 of the present invention is designed to be relatively larger than that of ordinary slippers so that the foot can be inserted while wearing shoes. Similarly, the width and length of the lower sole member 11 are also designed to be relatively large.

[0029] The slipper part 10 of Fig. 4(b) is provided with a heel band 13 in addition to the slipper part 10 of (a), which allows the position of the shoe or foot inserted by the wearer to be more stable.

[0030] The slipper part 10 of Figure 4(c) is equipped with a band-shaped upper member 12 that is open on the toe side. The band-shaped upper member 12 that is open on the toe side makes it easy to insert a shoe and reduces restrictions on the size of the shoe that can be used. The band-shaped upper member 12 can also function to limit the range of movement of the wearer's shoe. The size of the opening on the toe side is optional. The slipper part 10 of Figure 4(d) is equipped with a heel band 13 in addition to the slipper part 10 of (c).

[0031] 5(a) to 5(d) are schematic perspective views showing examples of modified forms of the joint between the slipper portion 10 and the lower garment portion 20. Fig. 5(a) shows an example of the slipper portion 10 having a dome-shaped upper member 12, in which the edge 22a of the leg portion 22 is joined to the heel side of the side surface 11b of the lower sole member 11 of the slipper portion 10 at a joint 51, and is joined to the edge 12a of the upper member 12 at a joint 52. In this case, the edge 22a of the leg portion 22 needs to be formed into a shape that extends along the edge 12a of the upper member 12 and the side surface 11b of the lower sole member 11. The inner diameter of the leg portion 22 needs to be large enough to allow the foot to be easily inserted while wearing the shoe.

[0032] It is preferable that the joint 51 with the side surface 11b of the lower base member 11 is formed at a distance d above the lower surface of the lower base member 11. The distance d is, for example, about 1 to 2 mm. This is to prevent the edge of the joint 51 from coming into contact with the road or the like and being rolled up or damaged when walking.

[0033] 5(b), the slipper part 10 has the same shape as in (a), but the edge 22a of the leg part 22 is joined to the entire periphery of the side surface 11b of the lower sole member 11 of the slipper part 10 at a joint 51. In this case, the edge 22a of the leg part 22 can be simply circumferential, making it easy to manufacture. Also, because the inner diameter of the lower garment part 20 is large, it is easy for the wearer to put their legs in, making it easier to put on the raincoat.

[0034] 5(c) shows an example of a slipper part 10 having a band-shaped upper member 12. The edge 22a of the leg part 22 is joined to the entire circumference of the side surface 11b of the lower sole member 11 of the slipper part 10 at a joining portion 51, and is joined to the upper member 12 at a joining portion 52. The joining portion 52 may be formed over the entire band width of the upper member 12 or over a portion of the band width, as necessary. In this case, the opening on the toe side of the upper member 12 is closed by the sheet material of the leg part 22.

[0035] In Figure 5(d), the shape of the slipper part 10 is the same as in (c), but the shape of the edge part 22a of the leg part 22 is the same as in (b), and is joined to the entire circumference of the side surface 11b of the lower base member 11 of the slipper part 10 at a joint 51.

[0036] In either case, the lower opening of the leg portion 22 of the lower garment portion 20 is sealed from the outside of the raincoat by the slipper portion 10, thereby ensuring waterproofing.

[0037] FIG. 6 is a schematic perspective view of the vicinity of the slipper part 10 when the raincoat of the present invention is worn over shoes S.

[0038] 7(a) to 7(e) are diagrams showing an example of how to fold the raincoat 1 shown in Fig. 1. The raincoat of the present invention is composed of the hood part 40, the upper part 30, and the lower part 20, all made from lightweight, thin sheets, and the slipper part 10, made from a lightweight, flexible resin, so it can be folded compactly and carried around. By carrying it with you at all times, you can quickly respond to sudden heavy rain.

[0039] In the example of Figure 7, first (a) the arms 32 and hood 40 are folded over the torso 31, then (b) the slipper part 10 is folded forward over the torso 31. Then (c) the lower half is folded backward. Next, (d) the two slipper parts 10 are folded in half with the bottom surfaces facing each other. Then (e) the slipper part 10 is folded backward to reduce it to half its size. In this way, the slipper part 10 is preferably made of a material flexible enough to be able to be folded in half. It can be folded in this way and carried in a suitable bag.

[0040] Although a number of embodiments of the present invention have been described above, the present invention is not limited to these exemplary embodiments, and various modifications are possible. [Explanation of symbols]
