  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings as appropriate. Note that the embodiment described below is merely an example of the present invention, and it is needless to say that the embodiment of the present invention can be changed as appropriate without departing from the gist of the present invention.

[Schematic configuration of waist belt 100]
As shown in FIGS. 1 to 3, the waist belt 100 according to the embodiment includes a belt 10, a bag 20, a spacer 30, and a synthetic resin sheet 50.

  In the waist belt 100, the left-right direction 9, the up-down direction 7, and the front-rear direction 8 are defined as follows. The longitudinal direction of the waist belt (left-right direction in FIG. 3) is the left-right direction 9, and the direction (vertical direction in FIG. 3) perpendicular to the left-right direction 9 in the horizontal plane is the up-down direction 7. The front-rear direction 8 is a direction orthogonal to both the left-right direction 9 and the up-down direction 7 (a direction perpendicular to the paper surface in FIG. 3).

[Belt 10]
As shown in FIGS. 1 and 3, the belt 10 has a long frame 11 in the left-right direction 9. The frame 11 is the upper and lower edges of the bag 20, and is configured by sewing cloth or the like on the upper and lower edges of the bag 20. The dimension along the up-down direction 7 between the pair of frames 11 separated in the up-down direction 7 is short at each end in the left-right direction 9 and long at the center of the left-right direction 9. That is, the bag 20 has a shape in which the dimension along the vertical direction 7 is long at the center in the left-right direction 9 and the dimension gradually decreases toward both ends in the left-right direction 9. Both side portions in the left-right direction 9 of the pair of frames 11 extend along the up-down direction 7, and the upper and lower frames 11 are connected.

  The belt 10 includes fasteners 12A and 12B for connecting both ends in a state of being wound in an annular shape (hereinafter, both may be collectively referred to as a fastener 12). A hook-and-loop fastener is used for the fastener 12. The fastener 12A is sewn to the rear side of the frame 11. The fastener 12B is sewn to the front side of the frame 11. In a state in which the waist belt 100 is wound in an annular shape, the adhesive surfaces of the fasteners 12A and 12B are overlapped with each other, whereby both ends of the waist belt 100 are connected.

[Bag 20]
The bag 20 includes a mesh-like sheet 21A located on the rear side in the front-rear direction 8 and a mesh-like sheet 21B located on the front side (hereinafter, both may be collectively referred to as the sheet 21). Have.

  As shown in FIG. 2, the sheet 21 </ b> A and the sheet 21 </ b> B are connected to each other by a frame 11 at the upper and lower ends to form a bag shape.

  The sheet 21 has air permeability when air passes through the mesh gap. By using the sheet 21 on the entire surface of the bag 20 facing the front-rear direction 8, the bag 20 has air permeability in the front-rear direction 8.

  As shown in FIG. 3, the internal space of the bag 20 has a first dimension 22 along the vertical direction 7 at each end in the left-right direction 9 and a second dimension along the vertical direction 7 at the center of the left-right direction 9. Shorter than 23.

[Spacer 30]
The spacer 30 has a plate shape and is stored in the bag 20. The spacer 30 is integrally formed as a synthetic resin molded product, for example. As shown in FIG. 4, the spacer 30 includes a plurality of column bodies 31 that are arranged in the vertical direction 7 and the horizontal direction 9 at intervals, and extend in the front-rear direction 8. The column 31 is a quadrangular column having an internal space, and has an opening 32 communicating with the internal space on a side wall facing the vertical direction 7 and the horizontal direction 9.

  As shown in FIGS. 4 and 5, the pillar body has an upper bottom member 33, a lower bottom member 34, and four pillar members 35. The four column members 35 have elasticity, and are deformed by the compressive force in the front-rear direction 8 to return to elasticity. Thereby, the column 31 is elastically deformed by the compressive force in the front-rear direction 8.

  The spacer 30 includes a flexible connecting member 36 that connects the column bodies 31 to each other. The connecting member 36 has a flat plate shape in a plan view that extends in the up-down direction 7 or the left-right direction 9 by connecting the lower bottom members 34 of the column bodies 31 located adjacent to each other in the up-down direction 7 and the left-right direction 9. In the side view, it has an arch shape that swells to the rear side. As the connecting member 36 bends in the front-rear direction 8, the spacer 30 has flexibility.

  The spacer 30 has a plurality of first gas flow paths 37 that open to the upper surface 41 and the lower surface 42 and communicate with the opening 43. The first gas channel 37 extends along the up-down direction 7. The first gas flow path 37 is a space defined by the column bodies 31 that are lined up in the up-down direction 7 and the connecting members 36 that connect the column bodies 31.

  The spacer 30 has a plurality of second gas channels 38 that communicate with the plurality of first gas channels 37. The second gas channel 38 extends along the left-right direction 9. The second gas flow path 38 is a space defined by the columnar bodies 31 that are lined up in the left-right direction 9 and the connecting members 36 that connect the columnar bodies 31.

  The plurality of first gas passages 37 and the plurality of second gas passages 38 cross each other in a lattice shape. In the spacer 30, the gas flows through the first gas channel 37 and the second gas channel 38 at random.

  As shown in FIG. 3, the third dimension 39 along the vertical direction 7 at each end of the spacer 30 in the left-right direction 9 is longer than the first dimension 22 and shorter than the second dimension 23.

  As shown in FIGS. 1 to 3, the synthetic resin sheet 50 is accommodated in the bag 20 and is located on the inner surface side of the belt 10 wound in an annular shape from the spacer 30, that is, on the front side in the front-rear direction 8. . The synthetic resin sheet 50 is fixed to the bag 20 by sandwiching the upper and lower ends of the center in the left-right direction 9 by the respective frames 11 bent in a U-shape and sewing together with the sheet 21.

  The dimension of the synthetic resin sheet 50 in the left-right direction 9 is slightly longer than the dimension of the spacer 30 in the left-right direction 9. The synthetic resin sheet 50 extends in the left-right direction 9 to the middle of the belt 10 in the left-right direction 9 and between the end portions. The synthetic resin sheet 50 does not allow gas to pass to the extent that the user wearing the waist belt 100 can feel it.

[Usage of waist belt 100]
As shown in FIG. 6, the waist belt 100 is wound around the user's waist so that the front side, that is, the synthetic resin sheet 50 is on the user side, and the spacer 30 is located on the outside. The user wears pants or the like on the outside of the waist belt 100. That is, the waist belt 100 is interposed between the user's waist and trousers. In addition, the user wears an outerwear such as air-conditioning clothes on the outside of the waist belt 100. That is, the waist belt 100 is interposed between the user's waist and outerwear.

  If the outer garment is an air-conditioning garment, an air flow is generated between the air-conditioning garment and the upper body of the user by operating a fan included in the air-conditioning garment. This airflow passes through the bag 20 of the waist belt 100 and flows into the opening 43 of the spacer 30. In the spacer 30, the atmosphere flows along the first gas flow path 37 and the second gas flow path 38 as indicated by arrows and dotted lines in FIG. 6. Thereby, the airflow generated between the air-conditioning clothing and the user's upper body flows between the pants and the user's lower body via the waist belt 100. Further, since the synthetic resin sheet 50 exists inside the spacer 30, the air flowing through the first gas flow path 37 and the second gas flow path 38 of the spacer 30 does not blow on the user's waist.

[Effects of Embodiment]
According to the waist belt 100 according to the embodiment, the spacer 30 may be stored in the bag 20 without being directly attached to the belt 10, so that the waist belt 100 can be easily manufactured. In addition, since the spacer 30 has flexibility, it is easy for the user to bend or twist the waist even when the waist belt 100 is worn. Further, the gas flowing in the spacer 30 flows from one first gas channel 37 to the other first gas channel 37 via the second gas channel 38, so that the gas flows in the vertical direction 7 and the horizontal direction 9. It will flow through and has excellent breathability.

  Further, since the column 31 has elasticity, the gas flow path in the spacer 30, that is, the first gas flow path 37 and the second gas flow path 38, even when a load in the front-rear direction 8 is applied to the waist belt 100. The gas is kept flowing. Further, when the load is lost, the column 31 is elastically restored. Since the connecting member 36 is flexible and the column 31 is a quadrangular column and has an internal space, a gas flow path in the spacer 30 is ensured even when the waist belt 100 is bent. The

  From the relationship between the first dimension 22 and the second dimension 23 of the bag 20 and the third dimension 39 of the spacer 30, the end portions in the left-right direction 9 of the spacer 30 are the center and end portions in the left-right direction 9 inside the bag 20. Therefore, the spacer 30 in the bag 20 can be positioned in the left-right direction 9.

  Since the bag 20 has the sheet 21 on the surface facing the front-rear direction 8, it is possible to secure a ventilation amount of the bag 20 that can store the spacer 30. Since the synthetic resin sheet 50 is provided on the body side from the gas flow path, the gas flowing through the spacer 30 can be prevented from hitting the waist. Moreover, the waist belt 100 can be prevented from being deformed. Moreover, since the synthetic resin sheet 50 has a heat retaining effect and has a cold protection function, the waist of the wearer is warm even in winter.

[Modification]
As mentioned above, although embodiment of this invention has been described in detail, the above description is only illustration of this invention in all the points. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. Regarding each component of the waist belt 100 according to the embodiment, the component may be omitted, replaced, and added as appropriate according to the embodiment. In addition, the shape and size of each component of the waist belt 100 may be appropriately set according to the embodiment. For example, the following changes can be made.

  The waist belt 100 according to the embodiment includes the frame 11, but instead of the frame 11, as shown in FIG. 7, the frame 211 of the belt 210 in the waist belt 200 has each end from the center in the left-right direction 9. The upper part and the lower part gradually approach each other while bending as in the embodiment, that is, the dimension along the vertical direction 7 is not gradually reduced, but along the edge of each end of the spacer 30 in the left-right direction 9. It may be a step.

  The waist belt 100 according to the embodiment includes the belt 10 having the frame 11, but may be a belt including a flat plate instead of the frame 11.

  Moreover, although the fastener 12 of the belt 10 according to the embodiment is a hook-and-loop fastener, it may be a buckle used for other ordinary belts.

  Further, the bag 20 may not be directly attached to the belt 10. For example, the bag 20 and the belt 10 may be indirectly connected by interposing another part between the bag 20 and the belt 10 and attaching the bag 20 to a part connected to the belt 10.

  The dimension of the internal space of the bag 20 may be shorter than the first dimension 22 along the vertical direction 7 between the center in the left-right direction 9 and each end. Even with such a configuration, the spacer 30 can be positioned in the left-right direction 9.

  The bag 20 has the sheet 21 on the entire surface facing the front-rear direction 8, but the sheet 21 may be provided only on a part of the bag 20.

  The mesh of the sheet 21 may be one in which hexagonal opening regions are arranged in a honeycomb shape.

  In addition, as shown in FIG. 7, a bag 220 having an openable / closable opening 224 may be provided instead of the bag 20. The opening 224 is opened and closed by a wire fastener 225, for example. According to this configuration, since the spacer 30 can be taken out from the internal space of the bag 220 through the opening 224, the replacement work of the spacer 30 is easy. Further, the bag 220 and the belt 210 can be separated from the spacer 30 and can be washed by the user.

  In addition, the spacer 30 according to the embodiment is rectangular in plan view when viewed from the front-rear direction 8, but may be other shapes such as a rectangle with rounded corners or an ellipse. If the four corners of the spacer 30 are rounded or elliptical, the corners of the spacer 30 are prevented from being caught in the holes of the sheet 21.

  The spacer 30 according to the embodiment has a single flat plate shape, but may be arranged in parallel in the vertical direction 7 or the horizontal direction 9 on the bag 20 as a plurality of elongated spacers, for example. For example, in the internal space of the bag 20, a plurality of storage chambers divided in the vertical direction 7 or the horizontal direction 9 are formed, so that the spacers can be stored in the respective rooms.

  The thickness of the spacer 30 is not particularly limited, but is preferably 5 mm to 10 mm. The waist belt 100 using the spacer 30 having such a thickness is thin enough to cause a sense of incongruity when the user rolls it, and can secure a gas flow path.

  In addition, the column bodies 31 of the spacer 30 according to the embodiment are arranged at intervals in the up-down direction 7 and the left-right direction 9 respectively, but even if the column bodies 31 are arranged at intervals only in the up-down direction 7, The column bodies 31 may be arranged in the direction 9 only at intervals. In this case, the column body 31 does not have a connecting member in the left-right direction 9 or the up-down direction 7, the column body 31 and the column body 31 are directly connected, and the connecting member is bent, whereby the spacer 30 is bent.

  Moreover, although the column 31 of the spacer 30 according to the embodiment is a quadrangular column, each vertex may be further rounded. With such a structure, the corner of the column 31 is prevented from being caught in the hole of the sheet 21. The column body 31 may not be a quadrangular column, but may be a cylinder, a triangular column, other polygonal columns, a truncated cone, or a polygonal truncated cone.

  Moreover, the opening 32 of the column 31 may be U-shaped or inverted U-shaped. Compared with the case where the opening 32 has a square shape, the pressure resistance of the column body 31 is increased in the column body 31 because one member on the front side or the rear side is thick. On the other hand, compared with the case where the opening 32 is a perfect circle or an ellipse, the column body 31 is excellent in air permeability because the surface area of one member on the rear side or the front side becomes narrow.

  Moreover, although the column 31 has the four column members 35, the number of the column members 35 of the column 31 may not be four. Moreover, it is preferable that the column member 35 is a cylindrical shape with a diameter of about 1.5 mm.

  Moreover, the upper bottom member 33 and the lower bottom member 34 of the column 31 may have openings. Moreover, the upper bottom member 33 and the lower bottom member 34 may have elasticity.

  In addition, the connecting member 36 of the spacer 30 according to the embodiment has a flat plate with an arch shape in a side view, but may be, for example, a rod instead of a flat plate, or may have a linear shape in a side view. . Further, the connecting member 36 may have an opening. The connecting member 36 may not be flexible, and the connecting portion with the column 31 may be bendable.

  Moreover, although the 1st gas flow path 37 of the spacer 30 which concerns on embodiment is extended in the up-down direction 7, you may extend in the diagonal direction. The first gas flow path 37 is not limited to the one defined only by the column body 31 and the connecting member 36, and may be defined by a pair of walls extending along the vertical direction 7, for example.

  Moreover, although the 2nd gas flow path 38 of the spacer 30 which concerns on embodiment is extended in the left-right direction 9, you may extend in the diagonal direction. The second gas flow path 38 is not limited to the one partitioned only by the column body 31 and the connecting member 36, and may be partitioned by a pair of walls extending along the left-right direction 9, for example. Further, the second gas flow path 38 may not be orthogonal to the first gas flow path.

  In addition, the plurality of second gas flow paths 38 of the spacer 30 according to the embodiment communicate with the plurality of first gas flow paths 37, and the second gas flow paths 38 are at least a pair of the first gas flow paths 37. May be communicated.

  As shown in FIG. 8, at least one or more openings 51 may be formed in the synthetic resin sheet 50. By appropriately forming the opening in the synthetic resin sheet 50, it is possible to prevent the circumference of the user's waist from being steamed.

  FIG. 8 is an exploded view of the waist belt 300. The waist belt 300 is obtained by providing a plurality of openings 51 in the synthetic resin sheet 50 of the waist belt 100.
