Have. As shown in FIGS. 1 and 2, the sheet 41A and the sheet 41B are connected by a frame 11 at the upper and lower ends, respectively.

The sheet 40 is breathable as air passes through the gaps in the mesh. By using the sheet 40 over the entire surface, the storage bag 20 is breathable in the front-rear direction 8.

[Synthetic resin sheet 50]
As shown in FIG. 1, the synthetic resin sheet 50 is housed in the sheet 40 and is located on the inner surface side of the belt body 10 wound in a ring shape from the rod-shaped spacer 30, that is, on the front side in the front-rear direction 8. ing. The synthetic resin sheet 50 is fixed to the storage bag 20 by being sandwiched between the upper and lower ends of the center in the left-right direction 9 by the U-shaped bent frames 11 and sewn together with the sheet 40.

The dimension of the synthetic resin sheet 50 in the left-right direction 9 is slightly longer than the dimension of the rod-shaped spacer 30 in the left-right direction 9. The synthetic resin sheet 50 extends in the left-right direction 9 from the center of the belt body 10 in the left-right direction 9 to each end. The synthetic resin sheet 50 does not allow gas to permeate to the extent that the user (worker) wearing the belt 100 can experience it.

In the above embodiment, the belt 100 to be worn on the waist has been described, but the belt 100 of the present invention is not limited to the one worn on the waist, and can be worn on the shoulder or on the back. , Can also be attached to the back of the thigh.

FIG. 5 is a top view of the belt applied to the thigh. The belts shown in FIGS. 1 to 4 are applied to the waist, while the belts shown in FIG. 5 are applied to the thighs. By making the shape optimal for each part in this way, it is possible to create a belt that can follow any part of the body.

[How to use the belt 100]
FIG. 6 is a reference diagram showing a usage pattern when the highly breathable belt 100 of the present invention is attached to both shoulders, back, waist, and thighs. In FIG. 6, the shoulder belt 200 can be hung from both shoulders and chucked in front of the operator. Further, the waist belt 100 can be wrapped around the waist and fixed. Further, the thigh belt 300 can be wound around the thigh and fixed. The waist belt 100 and the thigh belt 300 are fixed to each other with rubber 39. Therefore, when the worker sits down, the rubber 39 expands and contracts so that the waist belt 100 and the thigh belt 300 can follow the worker, respectively.

As shown in FIG. 6, the belt 100 is on the front side. That is, the synthetic resin sheet 50 of the belt 100 is on the user side (worker side), and the rod-shaped spacer 30 is wrapped around the user's waist so as to be located on the outside. The user wears trousers 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 the trousers. In addition, the user wears a jacket such as air-conditioned clothes on the outside of the waist belt 100. That is, the waist belt 100 is interposed between the user's waist and the jacket.

If the jacket is air-conditioned clothes, the fan provided in the air-conditioned clothes is operated, and an air flow of air is generated between the air-conditioned clothes and the upper body of the user. This air flow 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 gas flow path of the rod-shaped spacer 30. As a result, the airflow generated between the air-conditioned clothes and the upper body of the user flows between the trousers and the lower body of the user via the waist belt 100. Further, since the synthetic resin sheet 50 exists inside the spacer 30, the atmosphere flowing through the gas flow path 37 of the spacer 30 does not blow to the waist of the user. The power source of the fan can be put in the pocket 210 of the shoulder belt 200.

[Action and effect of the embodiment]
According to the belt 100 according to the embodiment, the rod-shaped spacer 30 is not directly attached to the belt body 10, but only needs to be stored in the storage bag 20, so that the waist belt 100 can be easily manufactured. Further, although the waist belt described in Patent Document 1 has excellent breathability, the plate-shaped spacers are complicated to manufacture because a plurality of pillars are arranged in each of the vertical and horizontal directions and the pillars are connected by connecting members. there were. On the other hand, in the waist belt 100 of the present invention, the bent portion 38 can be formed by arranging a plurality of rod-shaped spacers 30 at predetermined intervals without connecting the pillars with a connecting member, so that it is easy. Can be manufactured.

Further, since the rod-shaped spacer 30 can be bent in the front-rear direction 8 starting from the chamfered portion of the long pillar body, the user can easily bend or twist the waist even when the waist belt 100 is attached. .. Further, the gas flowing in the rod-shaped spacer 30 flows into the gas flow path 37, and the air permeability is excellent.

Further, since the side wall 35 has elasticity, even when a load of 8 in the front-rear direction is applied to the waist belt 100, the gas flow path in the rod-shaped spacer 30, that is, the gas flow path is maintained in a state where the gas flows. Further, when the load is removed, the side walls 33 and 34 are elastically restored.

Due to the relationship between the first dimension 22 and the second dimension 23 of the storage bag 20 and the third dimension 39 of the spacer 30, each end of the rod-shaped spacer 30 in the left-right direction 9 is located at the center of the storage bag 20 in the left-right direction 9. Since it stays between each end, the rod-shaped spacer 30 can be positioned in the storage bag 20 in the left-right direction 9.

Since the storage bag 20 has the sheet 21 on the surface facing the front-rear direction 8, it is possible to secure the ventilation amount of the storage bag 20 capable of storing the rod-shaped spacer 30. Since the synthetic resin sheet 50 is provided on the body side of the gas flow path, it is possible to prevent the gas flowing in the rod-shaped spacer 30 from directly hitting the waist. Further, by storing a plurality of rod-shaped spacers 30 in the storage bag 20 of the waist belt 100, it is possible to prevent the waist belt 100 from losing its shape. Further, since the synthetic resin sheet 50 has a heat retaining effect and a cold protection function, the waist of the wearer is warm even in winter.

[Modification example]
Although the embodiments of the present invention have been described in detail above, the above description is merely an example of the present invention in all respects. Needless to say, various improvements and modifications can be made without departing from the scope of the present invention. With respect to each component of the waist belt 100 according to the embodiment, the component may be omitted, replaced, or added as appropriate according to the embodiment. Further, 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.

Further, although the waist belt 100 according to the embodiment includes a belt main body 10 having a frame 11, a belt having a flat plate may be used instead of the frame 11.

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

Further, the storage bag 20 does not have to be directly attached to the belt body 10. For example, another component is interposed between the storage bag 20 and the belt body 10, and the storage bag 20 is attached to the component connected to the belt body 10, so that the bag 20 and the belt body 10 are indirectly connected. You may.

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

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

Further, the mesh of the sheet 21 may have hexagonal opening regions arranged in a honeycomb shape.

Further, as shown in FIG. 3, instead of the storage bag 20, a bag 220 having an opening / closing opening 224 may be provided. The opening 224 is opened and closed by, for example, a wire fastener 225. According to this configuration, the spacer 30 can be taken out from the internal space of the bag 220 through the opening 224, so that the spacer 30 can be easily replaced. Further, the bag 220 and the belt 210 can be separated from the spacer 30 and can be washed by the user.

Further, the rod-shaped spacer 30 according to the embodiment has a rectangular shape when viewed from the front-rear direction 8, but may have other shapes such as a rectangle or an ellipse with rounded four corners. By making the four corners of the rod-shaped spacer 30 round or oval, it is possible to prevent the corners of the rod-shaped spacer 30 from being caught in the holes of the sheet 41.

The thickness of the rod-shaped spacer 30 is not particularly limited, but is preferably 5 mm to 10 mm. The waist belt 100 using the rod-shaped spacer 30 having this thickness can secure a gas flow path while being thin with little discomfort when the user winds it.

Further, although the rod-shaped spacers 30 according to the embodiment are arranged at intervals in the vertical direction, they may be arranged at intervals in the horizontal direction 9 instead of the vertical direction.

Further, although the rod-shaped spacer 30 according to the embodiment is a quadrangular prism, each apex may be further rounded. With such a structure, it is possible to prevent the corners of the long pillar from being caught in the holes of the sheet 21. Further, the shape of the rod-shaped spacer 30 does not have to be a square prism, and may be a cylinder, a triangular prism, other polygonal prisms, a truncated cone, or a polygonal pyramid.

Further, the opening of the rod-shaped spacer 30 may be U-shaped or inverted U-shaped. Compared with the case where the opening is square-shaped, the pressure resistance of the rod-shaped spacer 30 is increased by making one of the front side or the rear side member thicker in the long pillar body. On the other hand, as compared with the case where the opening is a perfect circle or an ellipse, the rod-shaped spacer 30 is excellent in air permeability because the surface area of one member on the rear side or the front side is narrowed.

Further, the rod-shaped spacer 30 has side walls 33 and 34, and the side walls 33 and 34 may be cylindrical with a diameter of about 1.5 mm.

Further, the upper bottom member 33 and the lower bottom member 34 of the long pillar body may have openings. Further, the upper bottom member 33 and the lower bottom member 34 may have elasticity.

The bent portion 38 may be cut from one end to the other end in the left-right direction of the long pillar body, or may be partially cut between one end and multiple ends.

Further, the gas flow path 37 of the spacer 30 according to the embodiment extends in the vertical direction 7, but may extend in the oblique direction.

As shown in FIG. 4, the synthetic resin sheet 50 may have at least one or more openings 51 formed. By appropriately forming an opening in the synthetic resin sheet 50, it is possible to prevent the area around the waist of the user from getting stuffy.

FIG. 4 is an exploded view of the waist belt 300. The waist belt 300 is a synthetic resin sheet 50 of the waist belt 100 provided with a plurality of openings 51.

The belt of the present embodiment is not limited to the waist belt, and can be suitably used for, for example, a shoulder belt. For example, in the shoulder belt 200 shown in the front view and the rear view of FIG. 6, it is preferable that two or three spacers 30 shown in FIG. 1 are arranged along both shoulders and nape of the operator.
