Description

[Technical Field]

[0001] The present disclosure relates to nightwear. [Background technology]

[0002] Various types of nightwear have been known for some time. Utility Model Registration No. 3103756 describes pajamas consisting of an upper garment and a lower garment. The upper garment has sleeves, and the sleeves have linings positioned inside the cuffs. The linings have openings through which the wearer's hands can be passed.

[0003] The lining is sewn to the inside of the sleeve so that the lining opening is located slightly inside the cuff. The lower garment has a hem, and the hem has an lining located inside the hem opening. The lining at the hem has an lining opening through which the pajama wearer's legs are passed. The lining at the hem is sewn to the inside of the hem so that the lining opening is located slightly inside the hem opening. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3103756 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, nightwear is sometimes required to ensure heat retention to keep the wearer's body warm, especially in winter. The aforementioned pajamas have a double-layered fabric for the sleeves and hem, making them less likely to feel cold. However, when wearing nightwear, there are cases where the wearer wants to roll up the sleeves or hem to do manual labor, etc. With the aforementioned pajamas, when the sleeves or hem are rolled up, the inner lining located inside the sleeves or hem is exposed, which can create an unnatural appearance. This can result in an unattractive appearance when the sleeves or hem are rolled up. Therefore, it is required that the pajamas be able to maintain a natural appearance even when the sleeves or hem are rolled up.

[0006] The present disclosure aims to provide nightwear that can ensure heat retention and maintain a natural appearance even when the sleeves or hem are rolled up. [Means for solving the problem]

[0007] One aspect of the present disclosure provides nightwear (1) comprising a body and a pair of sleeves. At least one of the pair of sleeves extends continuously from the body and comprises an outer tubular fabric having an opening through which the wearer's hands are passed, and an inner tubular fabric that protrudes from the opening of the outer tubular fabric. Inside the outer tubular fabric, one end of the inner tubular fabric in the axial direction, which is the direction in which the axis of the inner tubular fabric extends, is connected to the outer tubular fabric via a sewn part. The other end of the inner tubular fabric can be accommodated inside the outer tubular fabric between the sewn part and the opening. The other end is in a state in which the inner tubular fabric is extended in the axial direction. And the hand is not in protrudes from the opening at At least one of the pair of sleeves has an accommodation space between the outer tubular fabric and the inner tubular fabric for accommodating the rolled-up portion of the inner tubular fabric.

[0008] In this nightwear, the sleeves have an outer tubular fabric and an inner tubular fabric, and the inner tubular fabric protrudes from and retracts through an opening in the outer tubular fabric. By arranging the inner tubular fabric inside the outer tubular fabric in the sleeves, heat retention in the sleeves can be ensured. One end of the inner tubular fabric is connected to the outer tubular fabric via a sewn portion, and the other end of the inner tubular fabric can be housed inside the outer tubular fabric between the sewn portion and the opening. Therefore, when the sleeves are rolled up, the other end of the inner tubular fabric can be housed inside the outer tubular fabric, allowing the sleeves to look natural when rolled up. Therefore, a natural appearance can be maintained even when the sleeves are rolled up.

[0009] (2) In the above (1), the inner tubular fabric may have a first opening located at the other end and through which the wearer's fingers are inserted, and a second opening formed at a position different from the other end and through which a finger different from the wearer's fingers is inserted. In this case, the wearer's fingers are inserted through the first opening, and a finger different from the plurality of fingers is inserted through the second opening. Therefore, by inserting the wearer's fingers through each of the first opening and the second opening of the inner tubular fabric, it is possible to prevent the inner tubular fabric from being unintentionally rolled up.

[0010] (3) In the above (1) or (2), the nightwear may further include a high-necked collar. In this case, the high-necked collar can further enhance heat retention.

[0011] Nightwear according to another aspect of the present disclosure is (4) nightwear having a crotch and a pair of inseams, each of which has a hem. At least one of the pair of hems extends continuously from the crotch and has an outer tubular fabric having an opening through which the wearer's legs are passed, and an inner tubular fabric that protrudes from the opening of the outer tubular fabric. Inside the outer tubular fabric, one end of the inner tubular fabric in the axial direction, which is the direction in which the axis of the inner tubular fabric extends, is connected to the outer tubular fabric via a sewn part. The other end of the inner tubular fabric can be accommodated inside the outer tubular fabric between the sewn part and the opening. The other end is in a state in which the inner tubular fabric is extended in the axial direction. And the foot is not put through protrudes from the opening at At least one of the pair of hem portions has an accommodation space between the outer tubular fabric and the inner tubular fabric for accommodating the rolled-up portion of the inner tubular fabric.

[0012] In this nightwear, the hem has an outer tubular fabric and an inner tubular fabric, and the inner tubular fabric protrudes from an opening in the outer tubular fabric. By arranging the inner tubular fabric inside the outer tubular fabric at the hem, heat retention at the hem can be ensured. One end of the inner tubular fabric is connected to the outer tubular fabric via a sewn portion, and the other end of the inner tubular fabric can be housed inside the outer tubular fabric between the sewn portion and the opening. Therefore, when the hem is rolled up, the other end of the inner tubular fabric can be housed inside the outer tubular fabric, allowing the hem to look natural. Therefore, a natural appearance can be maintained even when the hem is rolled up.

[0013] (5) In the above (4), the inner tubular fabric may have a third opening located at the other end through which the wearer's fingers are inserted, and a fourth opening formed at a different position from the other end through which the wearer's heel is exposed. In this case, the wearer's fingers are inserted through the third opening, and the wearer's heel is inserted through the fourth opening. By having the fourth opening through which the heel is exposed in the inner tubular fabric, the shape of the inner tubular fabric can be simplified. That is, when the fourth opening through which the heel is exposed is formed, the shape of the inner tubular fabric through which the foot is inserted does not need to be folded like a sock, but can be a linear shape. This makes it easier to roll up the inner tubular fabric. When the inner tubular fabric has the fourth opening through which the heel is exposed, flexibility in accommodating the wearer's foot size can be enhanced. Furthermore, when the fourth opening through which the heel is exposed is formed, the foot is less likely to slip during walking, etc.

[0014] (6) In any of the above (1) to (5), the inner tubular fabric may be made of a fabric having higher elasticity than the outer tubular fabric. In this case, the inner tubular fabric can be easily extended and retracted from the outer tubular fabric because the inner tubular fabric has a higher elasticity than the outer tubular fabric. [Effects of the Invention]

[0015] According to the present disclosure, heat retention can be ensured and a natural appearance can be maintained even when the sleeves or hem are rolled up. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, an embodiment of nightwear according to the present disclosure will be described with reference to the drawings. In the description of the drawings, identical or corresponding elements are designated by the same reference numerals, and duplicate explanations will be omitted as appropriate. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional proportions and the like are not limited to those shown in the drawings.

[0018] Nightwear is clothing that can be worn at night. For example, nightwear can be loungewear worn before going to bed or clothing worn while sleeping (nightwear, pajamas). Nightwear according to one embodiment comprises a body and a pair of sleeves. The "body" refers to the part of the garment that covers the front and back of the body of the wearer of the nightwear. The "sleeves" refer to the tubular part of the garment through which the wearer's arms pass.

[0019] Nightwear according to another embodiment includes a rise and a pair of inseam sections. The "rise" refers to the portion of the garment that covers the upper side of the wearer's crotch. The "inseam" refers to the portion of the garment that covers the lower side of the wearer's crotch. Each of the pair of inseam sections has a hem. The "hem" refers to the tubular portion of the garment through which the wearer's legs pass.

[0020] In the nightwear according to the embodiment, at least one of the sleeves and the hem has an outer tubular fabric and an inner tubular fabric located inside the outer tubular fabric, and the inner tubular fabric protrudes from an opening in the outer tubular fabric. The "outer tubular fabric" is the part that constitutes the outer surface of the sleeve or hem. For example, the material of the outer tubular fabric is the same as the material of the body, rise, or crotch.

[0021] The "inner tubular fabric" refers to a fabric that is connected to the outer tubular fabric on the inside of the outer tubular fabric and is able to freely protrude into and retract from the opening of the outer tubular fabric. One axial end of the inner tubular fabric is connected to the outer tubular fabric on the inside of the outer tubular fabric via a sewn portion. The "sewn portion" refers to the portion where one end of the inner tubular member is sewn to the inside part of the outer tubular member.

[0022] The other end of the inner tubular fabric can be housed inside the outer tubular fabric between the sewn portion and the opening. This allows at least a portion of the inner tubular fabric to freely protrude into and retract from the inside of the outer tubular fabric. By including the outer tubular fabric and the inner tubular fabric, the nightwear according to this embodiment can exhibit high heat retention and has excellent design, as the inner tubular fabric can be rolled up inside the outer tubular fabric and still look natural.

[0023] (First embodiment) FIG. 1 is a diagram showing an upper garment 2 of nightwear 1 as an example according to the first embodiment. FIG. 2 is a diagram showing a lower garment 3 of the nightwear 1. The nightwear 1 is, for example, thermal pajamas worn in winter. The nightwear 1 comprises an upper garment 2 and a lower garment 3. For example, the material of the upper garment 2 and the material of the lower garment 3 are the same.

[0024] As an example, the top garment 2 and the bottom garment 3 are each made of fabric (woven fabric). For example, the top garment 2 has a heat-retaining structure 2A, and the bottom garment 3 has a heat-retaining structure 3A. As the top garment 2 and the bottom garment 3 each have the heat-retaining structures 2A and 3A, the nightwear 1 exhibits high heat retention.

[0025] The top 2 comprises a body 4, a pair of sleeves 5 extending from the body 4, and a collar 6 protruding upward from the body 4. The body 4 has a left body 4b and a right body 4c. The left body 4b covers the left upper half of the body of a wearer M (see FIG. 4) of the nightwear 1, and the right body 4c covers the right upper half of the body of the wearer M. The top 2 comprises a plurality of buttons 2b that fasten the right body 4c to the left body 4b, and a pocket 2c. For example, a plurality of buttons 2b are attached to the right body 4c, and buttonholes are formed in the left body 4b to fasten each of the buttons 2b. For example, the pocket 2c is sewn to each of the left body 4b and the right body 4c.

[0026] The sleeves 5 include a left sleeve 5b extending leftward from the upper part of the left body 4b, and a right sleeve 5c extending rightward from the upper part of the right body 4c. The wearer M's left arm is passed through the left sleeve 5b, and the wearer M's right arm is passed through the right sleeve 5c. The heat-retaining structure 2A of the upper garment 2 described above is provided, for example, at the cuffs of the left sleeve 5b and the right sleeve 5c. Details of the heat-retaining structure 2A will be described later.

[0027] The collar 6 is, for example, a high neck that protrudes upward from the upper end of the body 4. The collar 6 is tubular and covers the neck of the wearer M. The collar 6 has a right portion 6b located on the right side as seen from the wearer M wearing the nightwear 1, and a left portion 6c located on the left side as seen from the wearer M wearing the nightwear 1. For example, the top 2 has a button 2d attached to the right portion 6b, and a buttonhole formed in the left portion 6c through which the button 2d can be fastened.

[0028] The lower garment 3 has a rise 7 and a pair of inseam sections 8 extending downward from the rise 7. The lower garment 3 also has a waist section 9 located at the upper end of the rise 7. For example, a looped elastic cord is threaded through the inside of the waist section 9, which allows the waist section 9 to tighten around the waist of the wearer M. Each of the pair of inseam sections 8 has a hem 8b.

[0029] The thermal insulation structure 3A of the lower garment 3 is provided, for example, at each of the pair of hems 8b. For example, the thermal insulation structure 3A has a tubular outer fabric 3b that is continuous with the outer fabric of the lower garment 3, and a tubular inner fabric 3c that is attached by sewing to the inside of the outer fabric 3b. The upper end of the inner fabric 3c is sewn to the inside surface of the outer fabric 3b.

[0030] The outer fabric 3b has an outer opening 3d through which the legs of the wearer M are passed, and the inner fabric 3c has an inner opening 3f through which the legs of the wearer M are passed. The inner opening 3f is located inside the outer fabric 3b, and for example, the inner fabric 3c does not have a portion that protrudes from the outer fabric 3b. For example, the distance K1 from the sewn portion 3g of the inner fabric 3c relative to the outer fabric 3b to the inner opening 3f is shorter than the distance K2 from the sewn portion 3g to the outer opening 3d.

[0031] For example, the distance K1 is 5 cm or more and 25 cm or less, and the distance K2 is 10 cm or more and 30 cm or less. As an example, the distance K1 is 15 cm and the distance K2 is 20 cm. In this case, the inner opening 3f is located 5 cm more inward (upper) than the outer opening 3d in the outer fabric 3b.

[0032] For example, the material of the inner fabric 3c is the same as the material of the outer fabric 3b. As an example, the outer fabric 3b and the inner fabric 3c are each made of fabric (woven fabric). A circular elastic cord is passed through the inner opening 3f, and this elastic cord makes the perimeter of the inner opening 3f shorter than the perimeter of the outer opening 3d. In addition, the width of the inner opening 3f is shorter than the width of the outer opening 3d. The circular elastic cord passed through the inner opening 3f can tighten the wearer's M's legs.

[0033] Next, the thermal insulation structure 2A of the sleeves 5 will be described. The thermal insulation structure 2A has an outer tubular fabric 11 having an opening 11b through which the hands of the wearer M of the nightwear 1 are passed, and an inner tubular fabric 12 that protrudes from the opening 11b. The outer tubular fabric 11 extends continuously from the body 4. The inner tubular fabric 12 is sewn to the outer tubular fabric 11 on the inside of the outer tubular fabric 11.

[0034] FIG. 3 is a perspective view showing the heat-retaining structure 2A of the upper garment 2. As shown in FIGS. 1 and 3, the nightwear 1 has a tubular sewn portion 13 sewn to the inside of an outer tubular fabric 11, and an inner tubular fabric 12 is sewn to the sewn portion 13. As an example, the sewn portion 13 is a junction tubular fabric interposed between the outer tubular fabric 11 and the inner tubular fabric 12. The material of the sewn portion 13 is, for example, the same as the material of the outer tubular fabric 11. For example, the sewn portion 13 is the same fabric as the outer tubular fabric 11. As an example, the sewn portion 13 is made of woven fabric. The sewn portion 13 is, for example, made of a non-stretchable fabric. The sewn portion 13 has lower elasticity than the elasticity of the inner tubular fabric 12. For example, the sewn portion 13 is connected to the inner tubular fabric 12 by sewing. The inner tubular fabric 12 is folded back at the seam (boundary) with the sewn portion 13. For example, when it is hot, the wearer can naturally fold the inner tubular fabric 12 in toward the base of the wearer's arm. If the sewn portion 13 is made of a non-stretchable fabric, the seam with the inner tubular fabric 12 is firmly fixed, making it even easier to fold the inner tubular fabric 12.

[0035] Each of the outer tubular fabric 11 and the inner tubular fabric 12 can be rolled up. Figure 3 shows the outer tubular fabric 11 in a rolled-up state. For example, the material of the inner tubular fabric 12 is different from the material of the outer tubular fabric 11 (sewn portion 13). As an example, the inner tubular fabric 12 has higher stretchability than the outer tubular fabric 11. In other words, when the magnitude of the tensile force applied to the outer tubular fabric 11 and the magnitude of the tensile force applied to the inner tubular fabric 12 are the same, the inner tubular fabric 12 will stretch more than the outer tubular fabric 11.

[0036] For example, the thickness of the inner tubular fabric 12 is thicker than the thickness of the outer tubular fabric 11. In this case, the inner tubular fabric 12, which has an inner surface that comes into contact with the hands of the wearer M, is thicker than the outer tubular fabric 11, thereby improving the heat retention in the hands of the wearer M. As an example, the inner tubular fabric 12 is made of a knit material (knitted fabric).

[0037] The inner tubular fabric 12 may also be made of wool, silk, cotton, or cashmere. For example, the inner tubular fabric 12 may be made of the same material as that used for socks. In this case, the material of the socks that keeps the feet warm can be effectively used as the inner tubular fabric 12. For example, the inner tubular fabric 12 has more fluff than the outer tubular fabric 11.

[0038] Inside the outer tubular fabric 11, one end 12b of the inner tubular fabric 12 in the axial direction D, which is the direction in which the axis L of the inner tubular fabric 12 extends, is connected to the outer tubular fabric 11 via a sewn portion 13. Fig. 4 is a perspective view showing a state in which a wearer M has their hand H passed through the inner tubular fabric 12 protruding from the opening 11b of the outer tubular fabric 11. Fig. 5 is a diagram schematically showing cross sections of the outer tubular fabric 11 and the inner tubular fabric 12 when cut along a plane extending in the axial direction D.

[0039] 3 to 5, the other end 12c of the inner tubular fabric 12 protrudes from the opening 11b when the inner tubular fabric 12 is extended in the axial direction D. The inner tubular fabric 12 has a first opening 12d located at the other end 12c and through which multiple fingers F1 of the wearer M are inserted, and a second opening 12g formed on a side portion 12f of the inner tubular fabric 12 and through which a finger F2 different from the multiple fingers F1 of the wearer M is inserted. By inserting the multiple fingers F1 into the first opening 12d and the finger F2 into the second opening 12g in a state in which the inner tubular fabric 12 protrudes from the outer tubular fabric 11, the hand H can be kept warm more sufficiently.

[0040] As shown in Figure 1, the distance K3 from the end 13b of the sewn portion 13 opposite the inner tubular fabric 12 to the opening 11b of the outer tubular fabric 11 is, for example, 10 cm or more and 30 cm or less. The distance K4 from the first opening 12d of the inner tubular fabric 12 to the opening 11b of the outer tubular fabric 11 when the inner tubular fabric 12 is protruding from the outer tubular fabric 11 is, for example, 5 cm or more and 15 cm or less. In this case, high heat retention is ensured and the inner tubular fabric 12 can be more easily inserted and removed from the outer tubular fabric 11. As an example, the distance K3 is 20 cm and the distance K4 is 10 cm.

[0041] 3, for example, the length of the inner tubular fabric 12 in the axial direction D when a hand H is not passed through is longer than the length of the inner tubular fabric 12 in the width direction W when a hand H is not passed through. In this case, the length of the inner tubular fabric 12 in the axial direction D can be sufficiently ensured, further improving the warmth retention of the hand H.

[0042] As shown in FIG. 4, the first opening 12d is adapted to receive, for example, multiple fingers F1 (index finger, middle finger, ring finger, and little finger) of the wearer M other than the thumb. As an example, the second opening 12g is adapted to receive a finger F2, which is different from the multiple fingers F1, such as the thumb. In this manner, when the wearer M's fingers F1 other than the thumb are passed through the first opening 12d and the thumb is passed through the second opening 12g, the hand H can be sufficiently warmed and the inner tubular fabric 12 can be made to fit well around the hand H. When the finger F2 is not passed through the second opening 12g, the second opening 12g is shaped like a slit extending in the axial direction D.

[0043] Fig. 6 is a perspective view showing a state in which the inner tubular fabric 12 is housed inside the outer tubular fabric 11. Fig. 7 shows a cross section of the outer tubular fabric 11 and the inner tubular fabric 12 cut along a plane extending in the axial direction D in the state shown in Fig. 6. As shown in Figs. 6 and 7, the other end 12c of the inner tubular fabric 12 can be housed inside the outer tubular fabric 11 between the sewn portion 13 and the opening 11b of the outer tubular fabric 11.

[0044] For example, the sleeve 5 has an accommodation space 5d between the outer tubular fabric 11 and the inner tubular fabric 12 for accommodating the rolled-up portion 12h of the inner tubular fabric 12. The other end 12c of the inner tubular fabric 12 can be folded outward to roll up the inner tubular fabric 12, and the rolled-up portion 12h can be accommodated in the accommodation space 5d.

[0045] Alternatively, the outer tubular fabric 11 and the inner tubular fabric 12 may be rolled up and the outer tubular fabric 11 may be placed over the rolled-up portion 12h. In this case as well, the rolled-up portion 12h of the inner tubular fabric 12 is housed inside the outer tubular fabric 11. As described above, the inner tubular fabric 12 can be housed inside the outer tubular fabric 11 so as not to protrude from the outer tubular fabric 11, resulting in a natural appearance.

[0046] For example, in the nightwear 1 according to this embodiment, as shown in Fig. 8, it is possible to fold the inner tubular fabric 12 over the outside of the outer tubular fabric 11 and roll up the inner tubular fabric 12. In this case, even when it is hot, by rolling up the inner tubular fabric 12 over the outside of the outer tubular fabric 11, it is possible to achieve a comfortable sleep.

[0047] Next, the effects obtained from the nightwear 1 according to this embodiment will be described in more detail. As shown in Figures 3, 4, and 6, in the nightwear 1, the sleeves 5 have an outer tubular fabric 11 and an inner tubular fabric 12, and the inner tubular fabric 12 protrudes from an opening 11b in the outer tubular fabric 11. By arranging the inner tubular fabric 12 inside the outer tubular fabric 11 in the sleeves 5, heat retention in the sleeves 5 can be ensured.

[0048] One end 12b of the inner tubular fabric 12 is connected to the outer tubular fabric 11 via the sewn portion 13, and the other end 12c of the inner tubular fabric 12 can be housed inside the outer tubular fabric 11 between the sewn portion 13 and the opening 11b. Therefore, when the sleeves 5 are rolled up, the other end 12c of the inner tubular fabric 12 can be housed inside the outer tubular fabric 11, so that the sleeves 5 look natural when rolled up. Therefore, a natural appearance can be maintained even when the sleeves 5 are rolled up.

[0049] In this embodiment, the inner tubular fabric 12 may be made of a fabric that is more stretchable than the outer tubular fabric 11. In this case, since the stretchability of the inner tubular fabric 12 is higher than that of the outer tubular fabric 11, the inner tubular fabric 12 can easily appear and disappear from the outer tubular fabric 11.

[0050] In the present embodiment, the inner tubular fabric 12 has a first opening 12d located at the other end 12c and through which the fingers F1 of the wearer M are passed, and a second opening 12g formed at a position different from the other end 12c and through which a finger F2 different from the fingers F1 of the wearer M is passed. Thus, the fingers F1 of the wearer M are passed through the first opening 12d, and a finger F2 different from the fingers F1 is passed through the second opening 12g. Therefore, by passing the wearer's fingers F1, F2 through the first opening 12d and the second opening 12g of the inner tubular fabric 12, respectively, it is possible to improve the warmth of the hand H while preventing the inner tubular fabric 12 from being unintentionally rolled up.

[0051] In this embodiment, as shown in Figure 1, the nightwear 1 further includes a high-necked collar 6. Therefore, by having a high-necked collar 6, the heat retention properties of the nightwear 1 can be further improved.

[0052] (Second embodiment) 9 is a perspective view showing a lower garment 23 of nightwear as an example according to the second embodiment. Part of the configuration of the nightwear according to the second embodiment is the same as part of the configuration of the nightwear 1 described above. Therefore, in the following explanation, explanations that overlap with the explanation of the nightwear 1 will be omitted as appropriate.

[0053] The bottom garment 23 has a heat-retaining structure 23A that is different from the heat-retaining structure 3A described above. This allows the bottom garment 23 of the nightwear according to the second embodiment to exhibit even higher heat retention than the bottom garment 3 of the nightwear 1. The bottom garment 23 has a rise 27 and a pair of crotch sections 28 extending downward from the rise 27, and each of the pair of crotch sections 28 has a hem 29.

[0054] The thermal structures 23A of the lower garment 23 are provided at each of the pair of hems 29. The thermal structures 23A have, for example, an outer tubular fabric 31 having openings 31b through which the wearer's M feet S (see FIG. 10) are passed, and an inner tubular fabric 32 that protrudes from the openings 31b. For example, the outer tubular fabric 31 extends continuously from the crotch 27. The inner tubular fabric 32 is sewn to the outer tubular fabric 31 on the inside of the outer tubular fabric 31. The inner tubular fabric 32 may be sewn to the outer tubular fabric 31 via an intermediate tubular fabric such as the sewn portion 13 described above, or may be sewn directly to the outer tubular fabric 31.

[0055] Each of the outer tubular fabric 31 and the inner tubular fabric 32 can be rolled up. FIG. 10 is a perspective view showing the inner tubular fabric 32 with the wearer's foot S passed through and the outer tubular fabric 31 rolled up. FIG. 11 is an enlarged perspective view of the heel S1 of the foot S in FIG. 10. As shown in FIGS. 9 to 11, for example, the material of the inner tubular fabric 32 is different from the material of the outer tubular fabric 31, and the inner tubular fabric 32 has greater stretchability than the outer tubular fabric 31. For example, the thickness of the inner tubular fabric 32 is greater than the thickness of the outer tubular fabric 31. In this case, the inner tubular fabric 32, which has an inner surface that comes into contact with the wearer's foot S, is thicker than the outer tubular fabric 31, thereby improving the heat retention of the wearer's foot S.

[0056] As an example, the inner tubular fabric 32 is made of a mohair-like fabric. The inner tubular fabric 32 may also be made of the same material as the inner tubular fabric 12 described above. In this case, it is possible to improve the heat retention of the feet S of the wearer M. For example, the inner tubular fabric 32 is fluffier than the outer tubular fabric 31.

[0057] One end 32b of the inner tubular fabric 32 in the axial direction Y, which is the direction in which the axis X of the inner tubular fabric 32 extends, is connected to the outer tubular fabric 31 via a sewn portion 33. The other end 32c of the inner tubular fabric 32 protrudes from the opening 31b when the inner tubular fabric 32 is stretched in the axial direction Y.

[0058] The inner tubular fabric 32 has a third opening 32d located at the other end 32c and through which the wearer's M's fingers S2 (toes) are passed, and a fourth opening 32g formed on a side portion 32f of the inner tubular fabric 32 and through which the wearer's M's heel S1 is exposed. With the inner tubular fabric 32 protruding from the outer tubular fabric 31, the wearer's foot S can be kept sufficiently warm with the fingers S2 passed through the third opening 32d and the heel S1 exposed from the fourth opening 32g.

[0059] For example, the length of the inner tubular fabric 32 in the axial direction Y when the foot S is not put through is longer than the length of the inner tubular fabric 32 in the width direction Z when the foot S is not put through. In this case, the length of the inner tubular fabric 32 in the axial direction Y can be sufficiently ensured, further improving the heat retention for the foot S.

[0060] For example, all of the toes S2 of the foot S of the wearer M are passed through the third opening 32d, and the heel S1 is passed through the fourth opening 32g. By passing the toes S2 of the foot S through the third opening 32d and exposing the heel S1 of the foot S through the fourth opening 32g, the foot S can be sufficiently warmed and the inner tubular fabric 32 can fit well around the foot S.

[0061] 7, the other end 32c of the inner tubular fabric 32 can be accommodated inside the outer tubular fabric 31 up to the opening 31b of the outer tubular fabric 31. The other end 32c of the inner tubular fabric 32 can be accommodated inside the outer tubular fabric 31 from the sewn portion of the inner tubular fabric 32 to the outer tubular fabric 31 up to the opening 31b of the outer tubular fabric 31.

[0062] For example, the hem 29 has an accommodation space 29d between the outer tubular fabric 31 and the inner tubular fabric 32 for accommodating the rolled-up portion 32h of the inner tubular fabric 32. The other end 32c of the inner tubular fabric 32 can be folded outward to roll up the inner tubular fabric 32, and the rolled-up portion 32h can be accommodated in the accommodation space 29d.

[0063] Alternatively, the outer tubular fabric 31 and the inner tubular fabric 32 may be rolled up, and the rolled-up portion 32h may be covered with the outer tubular fabric 31. In this case, the rolled-up portion 32h of the inner tubular fabric 32 is also contained inside the outer tubular fabric 31. As described above, the inner tubular fabric 32 can be contained inside the outer tubular fabric 31 so that the inner tubular fabric 32 does not protrude from the outer tubular fabric 31, thereby achieving a natural appearance.

[0064] The effects and advantages of the nightwear according to the second embodiment will be described in more detail. In the nightwear according to the second embodiment, the hem 29 comprises an outer tubular fabric 31 and an inner tubular fabric 32, with the inner tubular fabric 32 emerging from an opening 31b in the outer tubular fabric 31. By arranging the inner tubular fabric 32 inside the outer tubular fabric 31 at the hem 29, heat retention at the hem 29 can be ensured. One end 32b of the inner tubular fabric 32 is connected to the outer tubular fabric 31 via a sewn portion, and the other end 32c of the inner tubular fabric 32 can be accommodated inside the outer tubular fabric 31 between the sewn portion and the opening 31b. Therefore, when the hem 29 is rolled up, the other end 32c of the inner tubular fabric 32 can be accommodated inside the outer tubular fabric 31, allowing the hem 29 to look natural. Therefore, even when the hem 29 is rolled up, a natural appearance can be maintained.

[0065] As shown in FIGS. 9 to 11 , in the second embodiment, the inner tubular fabric 32 has a third opening 32d located at the other end 32c through which the wearer's toes S2 are inserted, and a fourth opening 32g formed at a position different from the other end 32c and through which the wearer's heel S1 is exposed. Thus, the wearer's toes S2 are inserted through the third opening 32d, and the wearer's heel S1 is inserted through the fourth opening 32g. The presence of the fourth opening 32g through which the heel S1 is exposed allows the shape of the inner tubular fabric 32 to be simplified. That is, when the fourth opening 32g through which the heel S1 is exposed is formed, the shape of the inner tubular fabric 32 through which the foot S is inserted does not need to be folded like a sock, but can be linear. This makes it easier to roll up the inner tubular fabric 32. When the inner tubular fabric 32 has the fourth opening 32g that exposes the heel S1, it can be flexible to the size of the foot S of the wearer M. Furthermore, when the fourth opening 32g that exposes the heel S1 is formed, it can make the foot S less likely to slip when walking, etc.

[0066] Furthermore, in the first and second embodiments described above, the inner tubular fabric may be made of a fabric that is more stretchable than the outer tubular fabric. In this case, the inner tubular fabric has a higher stretchability than the outer tubular fabric, which allows the inner tubular fabric to easily appear and disappear from the outer tubular fabric.

[0067] The above describes various embodiments of nightwear according to the present disclosure. However, the present disclosure is not limited to the aforementioned embodiments and may be modified as appropriate within the scope of the claims. In other words, the shape, size, material, number, and arrangement of each part of the nightwear according to the present disclosure may be modified as appropriate within the scope of the above-mentioned gist.

[0068] For example, in the above-described embodiment, the inner tubular fabric 12 is described in which multiple fingers F1 other than the thumb of the wearer M are passed through the first opening 12d, and the thumb is passed through the second opening 12g. However, the types of fingers passed through the first opening and the second opening of the inner tubular fabric are not particularly limited. Furthermore, the inner tubular fabric may have one opening or three or more openings, and the number of openings formed in the inner tubular fabric is not particularly limited. Furthermore, the shape, size, and arrangement of the openings in the inner tubular fabric can be changed as appropriate.

[0069] For example, in the above embodiment, the nightwear 1 was described in which the inner tubular fabric 12 was sewn to a tubular sewn portion 13 sewn to the inside of the outer tubular fabric 11. However, the shape, size, number, material, and arrangement of the sewn portion can be changed as appropriate. Furthermore, the sewn portion may be a portion where the inner tubular fabric 12 is sewn directly to the inside of the outer tubular fabric 11.

[0070] For example, in the above-described embodiment, nightwear 1 was described in which an outer tubular fabric 11 and an inner tubular fabric 12 are provided on each of a pair of sleeves 5. However, nightwear in which the outer tubular fabric 11 and the inner tubular fabric 12 are provided on only one of a pair of sleeves may also be used. In the above-described embodiment, nightwear 1 was described as thermal pajamas worn in winter. However, nightwear according to the present disclosure may also be pajamas worn in seasons other than winter. In this way, the present disclosure is applicable to various types of nightwear.

[0071] (Example) Next, examples of nightwear according to the present disclosure will be described. Note that the present invention is not limited to the following examples. Multiple experiments were conducted on the nightwear according to the examples to verify its effects. In the experiments, subjects wore the nightwear according to the examples and the nightwear according to the comparative example, and the temperatures of the subjects' hands and feet were measured using thermocouples or thermography. Below, we will first describe the experiments using thermocouples.

[0072] (Experiment using thermocouples) Experiments using thermocouples were conducted on nightwear according to Example 1 and nightwear according to a comparative example. The nightwear according to Example 1 is nightwear 1 shown in FIGS. 1 and 2. The nightwear according to the comparative example is nightwear 1 without the thermal structures 2A and 3A. The nightwear was worn for 20 to 30 minutes in the experiment, and thermocouples were attached to both hands of the wearer with tape. More specifically, thermocouples were attached to the wrist and palm, respectively. The skin surface temperature was measured using the thermocouples for 20 to 30 minutes after putting on the nightwear. The wearer was allowed to stay in a room with a temperature of 10°C and a humidity of 50% RH. The nightwear was left in the room for one hour before the start of the experiment to acclimate to the environment, and the wearer was allowed to sit in a chair and rest five minutes before the start of the experiment.

[0073] FIG. 12(a) is a graph showing the results of measuring wrist temperature in an experiment using a thermocouple. FIG. 12(b) is a graph showing the results of measuring palm temperature in an experiment using a thermocouple. As shown in FIGS. 12(a) and 12(b), the nightwear of Example 1, which has a thermal structure 2A (outer tubular fabric 11 and inner tubular fabric 12) on both the wrist and palm, was found to maintain a higher temperature and provide better thermal insulation than the nightwear of the comparative example. Regarding wrist temperature, the nightwear of the comparative example dropped 2.3°C after 30 minutes of wear, while the nightwear of Example 1 dropped only 0.3°C after 30 minutes of wear. Regarding palm temperature, the nightwear of the comparative example dropped 4.0°C after 30 minutes of wear, while the nightwear of Example 1 dropped only 2.1°C after 30 minutes of wear.

[0074] (Experiment using thermography) Next, we will explain the experiment using thermography. In the experiment, the nightwear was worn for 20 to 30 minutes, and the temperature of the wearer's hands was measured using thermography. An infrared thermographic camera (manufactured by Nippon Avionics Co., Ltd.) was used as the thermograph. The temperature was measured using thermography immediately after putting on the nightwear and 20 minutes later. The wearer was made to stay in a room with a temperature of 10°C and a humidity of 50% RH. The nightwear was left in the room for one hour before the start of the experiment to allow it to acclimate to the environment, and the wearer was made to sit in a chair and rest five minutes before the start of the experiment.

[0075] Fig. 13(a) shows the results immediately after wearing the nightwear according to the comparative example, and Fig. 13(b) shows the results 20 minutes after wearing the nightwear according to the comparative example. Fig. 14(a) shows the results immediately after wearing the nightwear according to Example 1, and Fig. 14(b) shows the results 20 minutes after wearing the nightwear according to Example 1. Figs. 13(a), 13(b), 14(a), 14(b), and Figs. 15(a), 15(b), 16(a), and 16(b) described below. Regarding the thermography results, the closer the color is to black, the lower the temperature is, and the closer the color is to white, the higher the temperature is.

[0076] As shown in Figures 13(a) and 13(b), it was found that the hand temperature dropped significantly after 20 minutes of wearing the nightwear of the Comparative Example. In contrast, as shown in Figures 14(a) and 14(b), it was found that the wrist temperature dropped slightly after 20 minutes of wearing the nightwear of Example 1, but the temperature at the base of the hand remained almost unchanged. Thus, it was found that the nightwear of Example 1 exhibits higher heat retention than the nightwear of the Comparative Example.

[0077] In the above experiment using thermography, the temperature of the feet was also measured for subjects wearing the nightwear according to the comparative example and the nightwear according to Example 2. The nightwear according to Example 2 is the second embodiment of nightwear having an outer tubular fabric 31 and an inner tubular fabric 32 as shown in FIG.

[0078] FIG. 15(a) shows the foot temperature immediately after donning the nightwear of the comparative example, and FIG. 15(b) shows the foot temperature 20 minutes after donning the nightwear of the comparative example. FIG. 16(a) shows the foot temperature immediately after donning the nightwear of Example 2, and FIG. 16(b) shows the foot temperature 20 minutes after donning the nightwear of Example 2. As shown in FIGS. 15(a) and 15(b), it was found that with the nightwear of the comparative example, the temperature of the feet (particularly the instep) dropped significantly 20 minutes after donning. Specifically, after 20 minutes, the temperature of the instep dropped by 1.6°C and the temperature of the ankle dropped by 0.5°C. In contrast, as shown in FIGS. 16(a) and 16(b), it was found that with the nightwear of Example 2, the temperature of the feet increased 20 minutes after donning. Specifically, after 20 minutes, the temperature of the instep increased by 1.0°C and the temperature of the ankle increased by 1.6°C. As described above, it was found that the nightwear according to Example 2 exhibited higher heat retention than the nightwear according to the comparative example, and was able to warm the feet more effectively.
