Description

clothing

[0001] The present invention relates to a garment having a torso and sleeves.

[0002] Conventionally, in garments having sleeves, it is known that the sleeves can be configured to allow adjustment of the length around the cuff. For example, there is a garment in which an elastic rubber member is provided at the cuff so that the length around the cuff can be adjusted to fit the wearer's wrist circumference. On the other hand, as disclosed in Patent Document 1 below, there is also a garment in which the length around the cuff can be adjusted by providing a hook-and-loop fastener at the cuff. In this garment, as shown in Figure 14, the cuff is cut open to form a V-shaped slit 81. A loop portion 83 of a hook-and-loop fastener 82 is fixed to one part of the slit 81, and a hook portion 85 of the hook-and-loop fastener 82 is provided on a tab 84 extending from the other part. By engaging the hook portion 85 with an appropriate part of the loop portion 83, the length around the cuff can be adjusted.

[0003] In a piece of clothing provided with a stretchable rubber member at the cuffs, the rubber member stretches according to the size around the wearer's wrist, so the cuffs easily fit the size around the wrist. However, since the cuffs are always in a state of fitting snugly around the wearer's wrist or arm, the wearer may feel uncomfortable when putting on or taking off the clothing, or when rolling up the sleeves. On the other hand, in a piece of clothing where the length around the cuffs can be adjusted by a snap fastener 82, by disengaging the hook portion 85 from the loop portion 83, it is easy to put on and take off the clothing, and the sleeves can be easily rolled up. On the other hand, in a state where the hook portion 85 is engaged with the loop portion 83, since the length around the cuffs is fixed, the wearer may feel uncomfortable. That is, when the snap fastener 82 is adjusted so that the cuffs fit perfectly around the wearer's wrist size, when the wearer makes an action such as raising the arm, the displacement of the cuffs in the longitudinal direction of the arm is suppressed. For this reason, the follow-up of the cuffs is suppressed and the wearer may feel uncomfortable. On the other hand, when the snap fastener 82 is adjusted so that the length around the cuffs has a margin with respect to the wearer's wrist size, the cuffs are more likely to follow the movement of the wearer. However, since air circulates inside and outside the cuffs through the gap between the cuffs and the wearer's arm, the wearer may feel uncomfortable.

[0004] Japanese Patent Application Laid-Open No. 2009-167553

[0005] An object of the present invention is to provide a piece of clothing that can not only shorten the length around the cuffs when necessary, but also make it difficult for the wearer to feel uncomfortable even when the length around the cuffs is shortened.

[0006] A garment according to one aspect of the present invention comprises a torso, a sleeve extending from the shoulder portion of the torso, and a band member provided at the cuff of the sleeve. The band member is positioned such that its longitudinal direction is aligned with the cuff, with both ends in the longitudinal direction fixed to the sleeve and the portion between the ends not fixed to the sleeve. The length of the portion between the ends of the band member is less than half the length of the cuff circumference. The band member is elastic and can be wrapped around the end of the sleeve to the opposite side, and is configured to contract the cuff when wrapped around to the opposite side.

[0008] Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

[0009] (First Embodiment) As shown in Figure 1, the garment 10 according to this embodiment is configured as a jacket that can be worn as an outer garment. However, the garment 10 is not limited to a jacket, and may be, for example, a coat, blouson, jumper, parka, shirt, rain suit with an upper garment and trousers integrated, or winter suit with an upper garment and trousers integrated, which have a torso 11 and sleeves 12, 12. The garment 10 in Figure 1 is equipped with a hood 14 that covers the wearer's head, but the hood 14 is optional.

[0010] The garment 10 comprises a torso 11 that covers the wearer's torso, and left and right sleeves 12, 12 extending from the shoulder portions of the torso 11. The fabrics that make up the torso 11 and the sleeves 12 may be of any material.

[0011] A band member 20 is provided at the cuffs 16, 16 of the left and right sleeve portions 12, 12. The band member 20 is used to tighten the cuff 16 when necessary. As shown in Figure 2, the band member 20 is located at the upper sleeve side portion 16a of the cuff 16. In other words, the band member 20 is located on the portion of the sleeve portion 12 that faces away from the body portion 11.

[0012] The band member 20 is composed of a band-shaped or strip-shaped member extending in one direction, and is positioned on the outside of the sleeve portion 12 such that its longitudinal direction follows the direction of the cuff. Both ends of the band member 20 (the ends 20a on both sides in the longitudinal direction) are fixed to the sleeve portion 12. Specifically, the sleeve portion 12 has a pair of slits 23 formed at intervals in the direction of the cuff, and the ends 20a on both sides of the band member 20 are inserted into the corresponding slits 23. In this state, the longitudinal ends 20a of the band member 20 are fixed to the cuff 16.

[0013] As shown in Figure 3, the end 20a of the band member 20 is positioned between the outer fabric 25 and the inner fabric 26 that constitute the cuff 16. An adhesive layer 28 is provided between the end 20a of the band member 20 and the outer fabric 25, and the outer surface of the end 20a of the band member 20 is bonded to the inner surface of the outer fabric 25 via this adhesive layer 28. In addition, an adhesive sheet 29 is provided on the inner surface of the end 20a of the band member 20. The adhesive sheet 29 sandwiches the end 20a of the band member 20 between the outer fabric 25 and the adhesive layer 28, with one end bonded to the inner surface of the outer fabric 25 and the adhesive layer 28, and the other end bonded to the outer fabric 25. As a result, the end 20a of the band member 20 is also fixed to the outer fabric 25 by the adhesive sheet 29. The adhesive layer 28 is made of hot melt. The adhesive sheet 29 includes a hot melt layer and a fabric layer. This fabric layer is made of a woven fabric such as tricot. Note that the adhesive sheet 29 can be omitted.

[0014] The end portion 20a of the band member 20 may be adhered to the back fabric 26 instead of the front fabric 25. Furthermore, one of the adhesive layer 28 and the adhesive sheet 29 may be omitted. Also, the back fabric 26 of the sleeve portion 12 may be omitted. In this case, the end portion 20a of the band member 20 will be exposed on the inside of the front fabric 25.

[0015] The ends 20a of the band member 20 are fixed to the sleeve portion 12 by being bonded to the sleeve portion 12, but alternatively, the ends 20a may be fixed to the sleeve portion 12 by being sewn to it. For example, as shown in Figure 4, the ends 20a of the band member 20 may be located on the inside of the outer fabric 25 that constitutes the sleeve portion 12 and sewn to the outer fabric 25. Alternatively, as shown in Figure 5, the slit 23 may be omitted, and the ends 20a of the band member 20 may be located on the outside of the outer fabric 25 and sewn to the outer fabric 25. In addition, in Figures 4 and 5, an adhesive layer (not shown) may be provided between the band member 20 and the outer fabric 25. In this case, the sewn portion may be for reinforcement or for decoration.

[0016] Furthermore, the end portion 20a of the band member 20 may be inserted into the sewing portion 31 of the cuff 16, rather than being inserted into the slit 23, as shown in Figure 6. In other words, the end portion 20a of the band member 20 may be sewn together with the outer fabric 25 at the sewing portion 31 that sews the outer fabric 25 constituting the cuff 16 together.

[0017] Although both ends of the band member 20 are fixed to the sleeve portion 12, the portion of the band member 20 between both ends, that is, the intermediate portion 20b between the end portions 20a, 20a in the longitudinal direction, is not fixed to the sleeve portion 12. Therefore, the intermediate portion 20b can be separated from the sleeve portion 12.

[0018] As shown in Figure 2, the length between the two ends 20a, 20a of the band member 20 (the length of the intermediate part 20b) is less than half the length of the cuff circumference. When in the state shown in Figure 2, the band member 20 is said to be in its initial state. At this time, the band member 20 does not shorten the cuff 16, so the shape of the cuff 16 is in its natural state without any folded parts.

[0019] The band member 20 is elastic. That is, the band member 20 is equipped with an expandable layer 35 (see Figure 7) made of chloroprene foam, and is therefore expandable. However, when the band member 20 is in its initial state, it is not stretched, so the cuff 16 is not tightened in this state. The band member 20 can stretch to, for example, more than twice its length, but because the expandable layer 35 is made of chloroprene foam, even after prolonged use, there is little residual strain and it easily returns to its original length. In other words, when the expandable layer 35 is made of chloroprene foam, there is little deterioration of the expandable layer 35, so even after prolonged use, the band member 20 easily returns to its original state from a stretched state.

[0020] Furthermore, the stretchable layer 35 is not limited to being made of chloroprene foam, as long as it is made of an elastic material. For example, the stretchable layer 35 may be made of flat rubber or silicone rubber. Also, the stretchable layer 35 may be made of a stretchable fabric such as rib knit fabric or fabric using polyurethane yarn.

[0021] Furthermore, as shown in Figure 7, the band member 20 is equipped with a reinforcing layer 36 that covers the stretchable layer 35. The reinforcing layer 36 is provided on both the front and back sides of the stretchable layer 35 and is fixed to the stretchable layer 35. The reinforcing layer 36 expands and contracts in accordance with the expansion and contraction of the stretchable layer 35. The reinforcing layer 36 is made of a knitted fabric such as nylon or polyester (for example, jersey fabric). By providing the reinforcing layer 36, the stretchable layer 35 can be reinforced while preventing its elasticity from being hindered. Note that the reinforcing layer 36 is optional. Also, the reinforcing layer 36 is not limited to being provided on both the front and back sides of the stretchable layer 35, but may be provided on only one side.

[0022] The band member 20 can be wrapped around the opposite side of the cuff 16. Specifically, as shown in Figure 8A, the band member 20 is located outside the upper sleeve portion 16a of the sleeve 12. Then, as shown in Figure 8B, the middle portion 20b of the band member 20 is pulled with the other hand to stretch the band member 20 towards the tip of the sleeve 12, so that it goes over the tip of the sleeve 12. Then, as shown in Figure 8C, the band member 20 is wrapped around the opposite side (the lower sleeve side of the sleeve 12) portion 16b with its front and back reversed. As a result, the band member 20 is wrapped around the opposite side of its initial position.

[0023] Since the length of the band member 20 between its ends 20a is less than half the length of the cuff circumference, when the band member 20 is wrapped around the lower sleeve as shown in Figure 8C, the length of the band member 20 between its ends 20a exceeds half the length of the cuff circumference. Therefore, when the band member 20 is wrapped around the lower sleeve, a portion of the cuff 16 is folded and the cuff 16 becomes compressed.

[0024] However, since the band member 20 can stretch even when wrapped around the lower sleeve, the size of the cuff 16 can be changed by the stretching and contracting of the band member 20 in this state as well. Therefore, even if the position of the cuff 16 may shift in the length direction of the arm according to the wearer's movements, the band member 20 will stretch and contract accordingly, thus suppressing discomfort for the wearer. In addition, the band member 20 can stretch beyond the point where the cuff 16 returns to its state before being contracted. Therefore, the size around the cuff can be expanded to the size of the band member 20 in its initial state.

[0025] When the band member 20 is wrapped around the lower sleeve side, a portion of the cuff 16 bends. To control this bending, a core material 38 may be provided in the sleeve portion 12, as shown in Figure 9. When the band member 20 is wrapped around to the opposite side, the band member 20 is located on the lower sleeve side. For this reason, the core material 38 is positioned in the lower sleeve side portion 16b of the cuff 16.

[0026] Of the fabric constituting the cuff 16, the portion to which the core material 38 is fixed is less likely to bend even when the band member 20 is wrapped around to the opposite side. Therefore, the portion of the cuff 16 to which the core material 38 is placed conforms more easily to the wearer's arm, and by placing the core material 38 in the part that the wearer's arm is likely to come into contact with, comfort can be improved. Note that the core material 38 can be omitted.

[0027] Furthermore, the core material 38 is provided so as to correspond to an intermediate position between the ends 20a, 20a of the band member 20 when it is wrapped around the opposite side in the direction of the cuff. That is, the core material 38 may be located at the central position between the ends 20a, 20a when it is wrapped around the opposite side, or it may be located at a position that is off-center to one side of the central position between the ends 20a, 20a.

[0028] When the band member 20 is wrapped around to the opposite side, as shown in Figures 10A and 10B, the fabric constituting the cuff 16 is prone to folding on both sides of the core material 38. The core material 38 is positioned on the lower sleeve side, that is, on the palm side of the wearer's arm. Therefore, by causing the fabric constituting the cuff 16 to fold on both sides of the core material 38, the folded portion is less likely to come into contact with the palm side of the wearer's arm. In other words, the position of the core material 38 determines the position of the portion that folds at the cuff 16. Therefore, the position where the fabric is prone to folding can be set to a desired position.

[0029] As described above, in the garment 10 of this embodiment, the length between the longitudinal ends 20a, 20a of the band member 20 is less than half the length of the cuff circumference. Therefore, when the band member 20 is wrapped around the opposite side beyond the tip of the sleeve portion 12 from its initial position, the band member 20 functions to fold the cuff 16 in the circumferential direction. Thus, when necessary, the wearer can wrap the band member 20 around to the opposite side to shorten the cuff 16 as needed. On the other hand, when there is no need to shorten the cuff 16, the band member 20 can be left in its initial position without being wrapped around to the opposite side, and the cuff 16 can be kept in a state where it cannot be shortened. In other words, it can be used in two ways. Moreover, because the band member 20 is elastic, even when the cuff 16 is shortened, the length of the cuff circumference can be changed by the stretching and contracting of the band member 20. Therefore, even if the position of the cuff 16 changes in the length direction of the arm in accordance with the wearer's movements, the band member 20 stretches and contracts accordingly, which suppresses discomfort for the wearer. Furthermore, the simple component of the elastic band member 20 allows for two-way use and enables the cuff 16 to flexibly follow the movement of the arm.

[0030] Furthermore, by simply setting the ratio of the length between the ends 20a, 20a of the band member 20 (the length of the intermediate part 20b) to the length of the cuff circumference, the amount of shrinkage of the cuff 16 when the band member 20 is wrapped around to the opposite side can be set. Therefore, the amount of shrinkage of the cuff 16 can be easily set. For example, if the length between the ends 20a, 20a of the band member 20 is set to 2 / 5 of the length of the cuff circumference, when the band member 20 is wrapped around to the opposite side, the length of the cuff circumference will be shortened by 1 / 5. That is, the cuff 16 will shrink by 3 / 5 - 2 / 5 = 1 / 5 of the length of the cuff circumference. For this reason, the amount of shrinkage of the cuff 16 can be easily set. Moreover, unlike clothing that uses hook-and-loop fasteners to tighten the cuff, it is possible to adopt a shape for the cuff 16 that is continuous in the circumferential direction without forming a gusset. For this reason, it is possible to adopt a desired shape for the sleeve portion 12 in the initial state when the cuff 16 is not shrunk.

[0031] Furthermore, in this embodiment, the band member 20 is configured to stretch to the extent that the cuff 16 returns to its state before being contracted when wrapped around to the opposite side. Therefore, when the band member 20 is stretched while wrapped around to the opposite side, the size around the cuff can be expanded to the size of the band member 20 in its initial state. However, when the force stretching the band member 20 is removed, the cuff 16 will contract.

[0032] Furthermore, in this embodiment, since both ends 20a, 20a of the band member 20 are inserted into slits 23 provided in the sleeve portion 12 and fixed to the sleeve portion 12, even if the band member 20 is positioned outside the sleeve portion 12, both ends 20a, 20a of the band member 20 are not exposed to the outside of the sleeve portion 12. Therefore, it is possible to prevent the ends 20a of the band member 20 from getting caught on something, thereby suppressing deterioration or wear of the ends 20a.

[0033] Furthermore, in this embodiment, the band member 20 is positioned on the upper sleeve portion 16a of the sleeve 12 and is configured to be looped around the lower sleeve portion 16b of the sleeve 12. Therefore, when the cuff 16 is retracted, the band member 20 is looped around the lower sleeve portion 16b. This prevents the band member 20 from getting caught on anything. Also, since the band member 20 is positioned on the upper sleeve side, it is possible to use the band member 20 as a decoration for the sleeve 12.

[0034] (Other Embodiments) It should be noted that the embodiments disclosed herein are illustrative and not restrictive in all respects. The present invention is not limited to the embodiments described above, and various modifications and improvements are possible without departing from the spirit of the invention.

[0035] For example, in the above embodiment, the band member 20 is provided on the upper sleeve side portion 16a of the cuff 16, but it is not limited to this. As shown in Figure 11, the band member 20 may be positioned on the lower sleeve side portion 16b of the cuff 16, that is, on the portion of the sleeve 12 facing the torso 11. In this case, the band member 20 is wrapped around the upper sleeve side of the cuff 16 when the cuff 16 is shortened. In this case, since the band member 20 is located on the lower sleeve side when the cuff 16 is in its initial state, the band member 20 can be made less noticeable when the cuff 16 is not shortened.

[0036] Alternatively, the band member 20 may be positioned on the front side of the cuff 16 and wrapped around the back side, instead of being positioned on the upper and lower sleeve sides of the cuff 16.

[0037] Furthermore, in the above embodiment, the band member 20 is positioned on the outside of the sleeve portion 12, but as shown in Figure 12, the band member 20 may be positioned on the inside of the sleeve portion 12. In this case, as shown in Figure 13, by folding the cuff 16 outward, the band member 20 can be positioned on the outside of the cuff 16, so that the band member 20 can be wrapped around to the opposite side with the cuff 16 folded back. It is also possible to wrap the band member 20 around to the opposite side without folding back the cuff 16. In the configuration shown in Figure 12, the end 20a of the band member 20 is fixed to the back fabric 26 that constitutes the cuff 16. The end 20a of the band member 20 is inserted between the front fabric 25 and the back fabric 26 through a slit formed in the back fabric 26, for example, and adhered to the front fabric 25 or the back fabric 26. Alternatively, the end 20a of the band member 20 may be sewn to the back fabric 26.

[0038] Herein, we will give an overview of the above-mentioned embodiment.

[0039] (1) The garment according to the embodiment comprises a torso, a sleeve extending from the shoulder portion of the torso, and a band member provided at the cuff of the sleeve. The band member is positioned such that its longitudinal direction is along the cuff, with both ends in the longitudinal direction fixed to the sleeve and the portion between the ends not fixed to the sleeve. The length of the portion between the ends of the band member is less than half the length of the cuff circumference. The band member is elastic and can be wrapped around the end of the sleeve to the opposite side, and is configured to contract the cuff when wrapped around to the opposite side.

[0040] In the said clothing, the length between both longitudinal ends of the band member is less than half of the length around the cuff. Therefore, when the band member is looped around to the opposite side beyond the tip of the sleeve portion, the band member functions to fold and contract the cuff. Thus, when necessary, the wearer can contract the cuff as needed by looping the band member around to the opposite side. On the other hand, when there is no need to contract the cuff, if the band member is left in the initial state without looping it around to the opposite side, the cuff can be maintained in a non-contracted state. That is, it can be used in two ways. Moreover, since the band member has elasticity, the length around the cuff can be changed by the expansion and contraction of the band member even when the cuff is contracted. For this reason, even if the position of the cuff changes in the length direction of the arm according to the movement of the wearer, the band member expands and contracts accordingly, so that it is possible to suppress the wearer from feeling discomfort. Also, with only a simple component, the elastic band member, it is possible to use it in two ways and for the cuff to flexibly follow the movement of the arm.

[0041] (2) The band member may be configured to stretch to such an extent that it returns to a state before the cuff is contracted when looped around to the opposite side.

[0042] In this aspect, when the band member is looped around to the opposite side and the band member is stretched, the size around the cuff can be expanded to the size when the band member is in the initial state. However, when the force stretching the band member is removed, the cuff is contracted again.

[0043] (3) Both ends of the band member may be inserted into slits or sewing portions provided in the cuff and fixed to the sleeve portion.

[0044] In this aspect, since both ends of the band member are inserted into the slits or sewing portions of the sleeve portion, both ends of the band member do not protrude from the sleeve portion. Therefore, it is possible to prevent the ends of the band member from getting caught on something, and thus suppress deterioration or wear of the ends. This aspect is particularly effective when the band member is located outside the cuff.

[0045] (4) The sleeve portion may be provided with a core material that suppresses the bending of the fabric constituting the cuff in a state where the band member is wound around the opposite side.

[0046] In this aspect, the fabric located at the portion where the core material is provided in the cuff is difficult to bend even when the cuff is contracted. Therefore, since the portion where the core material is arranged in the cuff is likely to follow the wearer's arm, the core material is arranged at a portion where the wearer's arm is likely to hit, so that the comfort can be improved. Further, since the position of the core material is determined, the position of the portion that bends in the cuff is determined, so that the position where the fabric is likely to bend can be set at a desired position.

[0047] (5) The band member may be arranged at a portion on the upper sleeve side of the cuff and configured to be wound around a portion on the lower sleeve side of the cuff.

[0048] In this aspect, when the cuff is contracted, the band member is wound around the lower sleeve side. Therefore, in this state, it is possible to prevent the band member from being caught on something.

[0049] (6) The band member may be arranged at a portion on the lower sleeve side of the cuff and configured to be wound around a portion on the upper sleeve side of the cuff.

[0050] In this aspect, when the band member is in the initial position, the band member is located on the lower sleeve side. Therefore, when wearing without contracting the cuff, the band member can be made less conspicuous.

[0051] (7) The band member may include a stretch layer made of an elastic material and a reinforcing layer fixed to the stretch layer and following the stretching and contracting of the stretch layer.

[0052] In this aspect, the stretchability of the band member is ensured by the stretch layer. Further, since the reinforcing layer is provided, it is possible to reinforce the stretch layer while preventing the stretchability of the stretch layer from being inhibited.

[0053] As described above, according to the garment of the embodiment, not only can the length around the cuff be shortened when necessary, but the wearer is less likely to feel uncomfortable even when the length around the cuff is shortened.

[0054] To illustrate the present invention, the embodiments have been adequately and fully described above with reference to the drawings. However, those skilled in the art should recognize that it is easy to modify and / or improve upon the embodiments described above. Therefore, unless such modifications or improvements implemented by those skilled in the art fall outside the scope of the claims, such modifications or improvements shall be considered to be included within the scope of the claims.
