Description

  The present invention relates to a waist belt or a lower garment having an adjustment mechanism that can cope with waist movement and waist size change.

Generally, the waist belt of the lower garment is provided with a mechanism for adjusting the size in stages so as to be matched to the wearer's waist size.
In order to fit the lower garment to the waist, an elastic member is used as a part of the waist belt to give an appropriate tightening force.

For example, Japanese Patent Application Laid-Open No. 2002-339113 discloses a garment with a waist size adjusting mechanism to which a coupling tool including a garment clasp for coupling a split part of a waist part of trousers is attached.
However, in the adjusting mechanism of the present invention, the size of the waist belt after using the coupling tool is fixed and cannot cope with the movement of the waist or the change in the waist size, which causes a decrease in comfort.

Japanese Patent Application Laid-Open No. 11-140710 discloses a size adjusting mechanism in which a cutout portion is provided in the waist belt and the body, and a stretchable elastic band is disposed in the cutout portion of the waistbelt.
However, in the adjusting mechanism of the invention, a tightening force is always applied to the waist, which causes a decrease in comfort.

  Therefore, the present invention intends to provide a waist belt or a lower garment having an adjustment mechanism that can appropriately fix the waist size during normal times and can respond to the movement of the waist or changes in the waist size during exercise or the like. .

  The invention of claim 1 is a lower garment in which the lower end of the waist belt is sewn to the body, wherein the waist belt has at least one notch portion, and an elastic member is sewn to the notch end, A cover member is disposed so as to cover the notch portion and the expansion / contraction member, and has an adjustment mechanism provided with attachment means on the outside of both ends of the notch portion, which can select fixing and releasing of the cover member and the waist belt. A garment with a waist belt.

  In the present invention, the waist belt and the cover member are fixed on the outer sides of both ends of the notch so that the elastic member sewn in the notch has a natural length or is slightly tensioned. Normally, the waist belt and cover member are fixed and used, and when the waist moves or the waist size changes during exercise etc., the waist belt and the cover member are released from the fixation, and the elastic member is used to release the waist. Have the freedom to increase the size.

  The invention of claim 2 is the lower garment characterized in that the upper end of the waist belt of the lower garment is shorter than the lower end of the waist belt.

  The inventor's research has revealed that the fit is improved by making the upper end of the waist belt shorter than the lower end of the waist belt, which is described in detail in Japanese Patent Application No. 2006-163849. However, if the upper end of the waist belt is shorter than the lower end of the waist belt, tension is easily applied to the upper end of the waist belt, so an even better fit can be obtained by providing an adjustment mechanism on the waist belt that can accommodate changes in waist movement and waist size. Can be provided.

  The invention according to claim 3 is the lower garment characterized in that the cutout of the cutout portion starts from the upper end of the waist belt and does not reach the lower end.

  According to the present invention, the waist belt is sewn to the lower garment at the lower end, but if there is no step on the sewn line of the notch if the notch does not reach the lower end, the sewn line may shift. The sewing thread will not break.

  Invention of Claim 4 is a waist belt, Comprising: The said waist belt has at least 1 or more notch part, the elastic member is sewn on the longitudinal direction both ends of the said notch part, The said notch part and said said A waist belt comprising a cover member disposed so as to cover the elastic member, and the cover member and the waist belt having an adjustment mechanism having attachment means that can be fixed or released outside both ends of the notch portion. It is.

  As described above, according to the present invention, the waist belt is normally fitted to the waist as a waist belt having a fixed waist size, and the waist belt is extended in accordance with the twist and elongation of the waist during exercise and the like. Can be obtained.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is an enlarged view of the adjusting mechanism 8 of the waist belt 1 of the present invention as viewed from the outside. The waist belt 1 is provided with a notch 6, and the elastic member 2 is sewn to the notches 7a and 7b. Further, a cover member 3 is provided so as to cover the cutout portion 6, and the waist belt 1 and the cover member 3 are fixed by the attachment means 4 outside the two cutout ends 7-a and 7-b. Is done.

  FIG. 2 is a cross-sectional view taken along the line A-A ′ of FIG. 1. The left side of the figure is the front of the lower garment, and the right side is the back. The stretchable member 2 is not fixed to the waist belt 1 or the cover member 3 except for the two notched ends, and is disposed so as to be freely stretchable. The cover member 3 is sewn to the body 10. The material of the stretchable member 2 may be a knitted fabric or a woven fabric, but it is desirable that the stretchable member 2 be a fabric having a greater stretchability in the weft direction than the sewn portion.

  For example, in the case of a knitted fabric, a rib structure or its changed structure is desirable, and it is used by knitting with a highly elastic yarn such as a polyurethane yarn, a stretchable polyester yarn, or a rubber yarn to enhance the stretchability in the weft direction. In the case of a woven fabric, it is used by increasing the stretchability in the weft direction by interweaving with highly stretchable yarn such as polyurethane yarn, stretchable polyester yarn, rubber yarn. Select one or more fibers from synthetic fibers such as polyester, nylon and acrylic, cellulosic fibers such as cotton, rayon and hemp, or animal fibers such as wool and silk. Or by knitting and weaving a part of highly elastic yarn such as polyurethane yarn, elastic polyester yarn, rubber yarn, etc. .

  Further, woven rubber can be used for the elastic member 2. In this case, a plurality of covering yarns covering polyester, nylon, etc. on a highly stretchable yarn such as polyurethane yarn in the length direction (warp direction), and nylon and polyester monofilaments in the width direction (weft direction) The yarn is arranged in a higher density than the warp direction, and is used by weaving so that the warp direction covering yarn is held so as not to move in the width direction. In order to further enhance the holding effect of the warp direction stretch yarns, it is also possible to use nylon heat fusion yarns in the weft direction, apply heat after rubber weaving, and bond at the intersections of the warp yarns.

  The above is an example, and the stretchable member 2 can be widely used as a stretchable member in the length direction. The width of the elastic member 2 is appropriately set according to the design of the garment, but the upper limit is preferably the same as the width of the waist belt 1 to be sewn, and the lower limit is preferably 15 mm narrower than the width of the waist belt 1. This is because if the width of the elastic member 2 is larger than the width of the waist belt 1, the processing becomes complicated. Further, when the elastic member 2 is narrowed by more than 15 mm than the width of the waist belt 1, damage to the heel and the sewing portion of the waist belt 1, and vertical folding of the cover member 3 in the direction from the waist belt upper end 15 to the waist belt lower end 14. It is because it becomes easy to occur.

  3 is a B-B ′ cross section of FIG. 1. The waist belt 1 and the cover member 3 are sewn to the body 10 near the lower end 14 of the waist belt, but are not sewn at other portions.

  FIG. 5 is an example in which the lower garment 5 provided with the adjusting mechanism 8 of the present invention on the side of the waist belt 1 is viewed from the side. In this embodiment, adjustment mechanisms 8 are provided at two locations on the left and right sides of the waist. If the waist belt 1 and the cover member 3 are fixed by the attaching means 4, a normal waist belt having a fixed waist size is obtained, and if the waist belt 1 is released, the waist belt 1 can be extended in accordance with twisting and stretching of the waist. In this embodiment, a button is used as the attaching means 4 for the waist belt 1 and the cover member 3, but a hook, buckle, can, hook fastener, or the like may be used. Moreover, the position where the adjusting mechanism 8 is provided is an example, and is not limited to the present embodiment, and may be provided in another place, for example, the back surface or the front surface.

  In the embodiment of FIG. 5, the main dimensions of the waist belt 1 are 67 cm at the upper end 15 of the waist belt, 81 cm at the lower end 14 of the waist belt, and 5.5 cm in width. Further, the waist belt 1 and the cover member 3 are made of woven fabric of 94% polyester and 6% polyurethane. The elastic member 2 uses 1240 dtex polyurethane yarn, 174 rubber yarns covering 150 dtex polyester twin yarn in the length direction (warp direction), and 300 dtex single polyester yarn in the width direction (weft direction). The total width was 4 cm. Further, the tension of the expansion / contraction member 2 was 30%, and the load at the time of elongation was 9.6N. In addition, in order to obtain a good fit, it is preferable that the load when the elastic member 2 is stretched by 30% is in the range of 3.5 to 15.7 N.

  The load measurement at the time of 30% expansion | extension of an expansion-contraction member is performed on condition of the following using TENSION type universal tensile testing machine UTM-3-200 (product made from Toyo Baldwin). The test piece is 3 cm wide × 30 cm long, and is prepared so that the weft direction is the length direction. The test piece is set so that the chucking interval is 20 cm, the chuck interval is widened at a speed of 20 cm per minute, and the load when the chuck interval is 26 cm is measured. In addition, when it is difficult to process the specimen width to 3 cm, such as woven rubber, the load at 30% elongation is converted as being proportional to the specimen width.

  The width of the waist belt 1 is preferably 4 cm to 7 cm, and more preferably 5 cm to 6 cm. The width of the normal waist belt is around 3 cm, but the waist belt lower end 14 does not expand and contract, so the adjustment mechanism 8 does not work sufficiently if the waist belt 1 has a width of 4 cm or more. Because.

  FIG. 6 shows the adjusting mechanism 8 of FIG. 1, but the cover material 3 is seen through for the sake of explanation. FIG. 6A shows a state in which both attachment means 4 are fixed, and functions as a normal waist belt having a fixed size. For this reason, the cover member 3 and the waist belt 1 are preferably made of a material having a small elongation. For example, the fabric is less stretchable than the stretchable member 2, or the stretch is suppressed by attaching an interlining to the back of the fabric.

FIG. 6b shows an example of use in a state where one attachment means 4-a is released. For example, when the golf club or the bat is swung or stretched in one direction, only the attachment means on the extending side is released. A suitable fit can be obtained.

FIG. 6c shows an example of use in a state in which both the mounting means 4-a and 4-b are released. For example, when the waist size is irregularly expanded, such as taking a forward bending flexible motion or taking a sitting position for a long time, the waist belt 1 Can extend to both sides of the notch 6 to obtain a good fit.

  In addition, the direction which the elastic member 2 provides near the waist belt upper end 15 can respond to a change in waist size better than the waist belt lower end 14 vicinity where a waist size is fixed. For this reason, in this embodiment, the elastic member 2 is arranged close to the upper end of the waist belt.

The waist belt of the present invention is generally provided in a lower garment, but can also be used for general clothing such as an upper garment or a waist supporter.
