[Figure 2] These are diagrams (a) showing the back view of the wearer and (b) showing the side view of the wearer, illustrating how the waist bag of this embodiment is worn. [Figure 3] This graph (a) shows the test results for the swaying sensation of the waist bag in this embodiment, and this sensory evaluation scale (b) shows the results. [Figure 4] This graph shows the test results for the amount of swing of the waist bag in this embodiment. [Modes for carrying out the invention]

[0013] The embodiments of this invention will now be described below with reference to the drawings. Figure 1 shows one embodiment of this invention, in which the waist bag 10 consists of a main body 12 having a longitudinal direction that is long in one direction, and the length of the longitudinal direction is such that it wraps around the waist of the wearer 30 once, but is slightly shorter than wrapping around completely.

[0014] The main body 12 is a deformed oval-shaped band with its longitudinal direction as the major axis. The upper side edge 12a and the lower side edge 12b, which are located above the wearer 30 when worn, are parallel to each other and both are arc-shaped with a slightly downward convex middle section, giving the entire main body 12 an approximate crescent shape. Figure 1(a) is a front view of the waist bag 10 as seen from the surface 12c, which is the side opposite to the wearer 30's body and is made of a durable fabric with moderate elasticity. Figure 1(b) is a front view of the waist bag 10 as seen from the back 12d, which is the side facing the wearer 30's body and is made of a mesh fabric that is comfortable against the skin and fits the body well. The main body 12 is formed by overlapping and sewing together the fabric on the surface 12c side and the mesh fabric on the back 12d side.

[0015] A pair of connecting ends 12e and 12f, located at both ends in the longitudinal direction of the main body 12, are each fitted with a pair of detachable connectors 14 and 16. The connectors 14 and 16 are, for example, buckles made of synthetic resin. One of the connectors 16 is attached to the connecting end 12f via a length-adjustable belt 18.

[0016] A cover member 20 is attached approximately to the center of the surface 12c of the main body 12. The cover member 20 is made of a trapezoidal, stretchable fabric or the like, and holds the contents in place from the outside. The fabric of the cover member 20 may be the same as the fabric forming the surface 12c, provided that the fabric forming the surface 12c has appropriate elasticity. The cover member 20 is placed on top of the surface 12c, and the upper side edge 20a of the trapezoidal cover member 20 is sewn to the side edge 12a of the main body 12, while the lower side edge 20b is sewn to the side edge 12b of the main body 12.

[0017] The pair of inclined edges 20c and 20d that intersect the side edges 20a and 20b are not sewn to the main body 12, leaving an opening between them and the surface 12c of the main body 12. The space between the cover member 20 and the surface 12c of the main body 12 becomes a storage compartment 22 capable of accommodating contents. The storage compartment 22 is cylindrical with the edges 20c and 20d opening outwards, and the openings of the pair of edges 20c and 20d become an access port 23 for inserting and removing contents from the storage compartment 22. The cover member 20 may have darts to create a slight gap and bulge from the flat surface 12c of the main body 12. Elastic cords may be sewn along the edges 20c and 20d to facilitate the holding of contents.

[0018] A pair of ring members 24 are attached to the edge portions 20c and 20d of the cover member 20, respectively, through which a fixing member described later is inserted and locked. Each ring member 24 is attached near the center of the respective length of the edge portions 20c and 20d.

[0019] The edge portion 20c is provided on a side closer to the connecting end 12e, and a belt 26 serving as a fixing member for fixing the cover member 20 is locked to the ring member 24 of the edge portion 20c. The belt 26 is a thin strip having no stretchability, one end 26a thereof is inserted through the ring member 24 and locked, and the opposite end 26b is sewn to a sewn portion 13 located near the end 12e spaced apart from the cover member 20 in the longitudinal direction of the main body portion 12 on the surface 12c of the main body portion 12. The length and tension of the belt 26 can be adjusted by pulling or loosening the end 26a to change the position where the belt 26 is locked to the ring member 24.

[0020] A thin non-stretchable belt 28, which is similar to the belt 26, is also locked to the ring member 24 of the opposite edge portion 20d. One end 28a thereof is inserted through the ring member 24 and locked, and the opposite end 28b is sewn to a sewn portion 13 located near the connecting end 12f spaced apart from the cover member 20 in the longitudinal direction of the main body portion 12 on the surface 12c of the main body portion 12. The length and tension of the belt 28 can also be adjusted by pulling or loosening the end 28a to change the position where the belt 28 is locked to the ring member 24.

[0021] Therefore, the pair of belts 26, 28 extend from the cover member 20 in opposite directions to each other along the longitudinal direction of the main body portion 12 of the storage portion 22. When the wearer 30 wears the waist bag 10, the belts 26, 28 are positioned along the waist circumference of the wearer 30, and are provided such that the length and tension thereof can be adjusted to fit the waist circumference by the ring members 24.

[0022] Next, a method of using the waist bag 10 of this embodiment will be described. First, the longitudinal direction of the main body portion 12 is wrapped around the waist of the wearer 30, the pair of connecting members 14 and 16 are engaged, and the wearing tightness is adjusted by the belt 18 of the length-adjustable connecting member 16, and then the waist bag is worn. At this time, the surface 12c of the main body portion 12 is on a side opposite to the body of the wearer 30, and the back surface 12d is in contact with the body. The cover member 20 is positioned on the back 30a of the wearer 30, and the connecting member 14 and the connecting member 16 are positioned on the abdomen 30b of the wearer 30.

[0023] Next, the contents are placed into the storage compartment 22 through the outlets 23 located at the edges 20c and 20d of the cover member 20. The contents are, for example, a bottle 32 containing a beverage. Because the cover member 20 is elastic, it is stretched to conform to the outer diameter of the bottle 32 and fits snugly against it. Alternatively, the bottle 32 may be placed in the storage compartment 22 of the main body 12 and then wrapped around the wearer's waist 30 for attachment.

[0024] With the waist bag 10 attached to the waist, the length of the pair of belts 26 and 28 is adjusted. The adjustment is done by pulling the ends 26a and 28a of the belts 26 and 28 forward by hand, while moving the edges 20c and 20d of the cover member 20 away from each other along the longitudinal direction of the main body 12. This pulls the cover member 20 along the longitudinal direction of the main body 12, pressing the bottle 32 against the main body 12 on the wearer's side, and securing it, resulting in the attached state shown in Figure 2. The wearer 30 then performs exercises such as running while wearing the waist bag 10.

[0025] The dispensing opening 23, located at the edges 20c and 20d, is pulled by a pair of belts 26 and 28 and pressed against the surface 12c, closing it and preventing the bottle 32 from accidentally falling out of the dispensing opening 23. When removing the bottle 32 from the storage compartment 22, the user reaches in through the dispensing opening 23, grasps the bottle 32, and pulls it out. Because the cover member 20 is elastic, it is possible to reach in and pull out the bottle 32. The bottle 32 can also be returned to the storage compartment 22 through the dispensing opening 23 without loosening the length of the pair of belts 26 and 28.

[0026] According to the waist bag 10 of this embodiment, a bottle 32 can be carried during exercise, and the shaking of the bottle 32 during exercise such as running is reliably suppressed so as not to hinder exercise, and the wearer can exercise comfortably with good comfort.

[0027] For example, when running, it can be used to store and wear valuables, drinks, and energy bars, allowing them to be carried without hindering running, keeping valuables safe, and allowing access to drinks and energy bars when needed. The cover member 20 is made of a trapezoidal, stretchable fabric that provides a wide surface area to support the lower part of the bottle 32, ensuring secure storage. The sloping edges 20c and 20d serve as the opening 23, allowing the user to reach in from diagonally above to insert and remove the bottle 32, enabling hydration without stopping while running.

[0028] Since the pair of belts 26 and 28 are positioned at the sides of the wearer's waist 30, when the wearer is wearing the device, the ends 26a and 28a can be pulled forward by hand to shorten the belts 26 and 28 through the ring member 24, allowing the cover member 20 to be pulled tightly towards the back 30a for adjustment. The force holding the bottle 32 can be easily adjusted even while running. For example, the cover member 20 can be tightened if it has become loose due to inserting or removing the bottle 32, or due to vibrations from exercise.

[0029] Since the pair of belts 26 and 28 are each positioned near the sides of the wearer 30, even when the belts 26 and 28 are shortened to press the bottle 32 more firmly against the back 30a, the wearer 30's abdomen 30b does not become constricted, and it does not hinder running.

[0030] The waist bag of this invention is not limited to the above embodiment, and the shape of the main body and cover members, as well as the belt attachment position, can be changed as appropriate. The connecting device can be anything other than a buckle that securely fastens. The fabric material can be freely selected, and the fabric on the front and back does not need to be stretchable, and the back does not have to be mesh fabric. Pockets for valuables, smartphones, snacks, etc. can be provided on the front and back of the main body. For example, as shown in Figure 1, a pocket 25 that can be opened and closed with a slide fastener 21 may be provided on the front 12c of the main body 12. In addition, although the front and back of the main body and the cover member are sewn together, they may also be attached by adhesive or other means. [Examples]

[0031] A test was conducted to measure the vertical movement of the waist bag 10, the invention of this application, during running, and to evaluate it as the amount of sway. In addition, the subjective feeling of swaying experienced by the wearer 30 during the test was evaluated subjectively. The subjects of the test were three adult males (size M). The test method involved wearing the waist bag 10 containing the contents and running on a treadmill. The running speed was 1 km / 6 min, the running time was 5 minutes, and the analysis interval was right foot strike-right foot strike × 5 cycles. The evaluation index was the subjective feeling of swaying and the amount of vertical swaying of marker A, which was attached to the lower part of the wearer 30's back 30a and near the center of the side edge 12a of the main body 12, as shown in Figure 2(a). For comparison, the same test was conducted with a comparative product similar to the waist bag of Patent Document 1.

[0032] The results of the vibration test are shown in the graph in Figure 3. The graph in Figure 3(a) shows the results of a sensory test conducted using the scale shown in Figure 3(b), with the vertical axis of Figure 3(a) representing the numerical value of the scale shown in Figure 3(b). The average vibration value of the sensory test results for the comparative product was approximately 2.8, while that of the waist bag 10 of the present invention was approximately 1.8, indicating that the vibration was smaller in the sensory test. The results of the vibration amount test are shown in the graph in Figure 4. The vibration amount for the comparative product was approximately 29 cm, while that of the waist bag 10 was approximately 16 cm. From the results of these two tests, it can be seen that the waist bag 10 of the present invention had less vibration in terms of sensory perception and less actual vibration compared to the comparative product. As a result, the waist bag 10 of the present invention reliably suppresses vibration during exercise such as running, does not hinder exercise, and allows for comfortable exercise.
