Description

  The present invention relates to a waist bag, and more particularly to a waist bag capable of storing a container so that a container such as a plastic bottle can be carried.

  Conventional waist bags have been improved in terms of functions such as storage capacity, weight reduction, breathability, and waterproofness. In addition, there are various uses for the waist bag, some of which are designed as bags that can be carried during exercise.

  For example, Japanese Unexamined Patent Application Publication No. 2010-188093 discloses a bottle holder that is fixed to an arm as a bottle holder that can be carried during exercise or movement. Japanese Patent No. 4549257 discloses a portable beverage container storage device that can be worn while keeping the right and left balance of the body without interfering with the movement of the wearer, and that allows easy loading and unloading of the beverage container.

JP 2010-188093 A Japanese Patent No. 4549257

  However, when carrying a storage tool during movement such as running, or when exercising, the waist bag tends to sway as the wearer sways. This hinders movement during exercise and leads to a load on the wearer's body.

  Japanese Patent Application Laid-Open No. 2010-188093 and Japanese Patent No. 4549257 provide a portable beverage container in a direction perpendicular to the belt, and is provided so that the belt and the storage portion are in wide surface contact. Absent. As a result, when moving or exercising with shaking, the conventional container storage device tends to swing both in the direction parallel to the belt and in the vertical direction. Furthermore, the bottle holder disclosed in Japanese Patent Application Laid-Open No. 2010-188093 has a configuration in which the central portion of the bottle is fixed with one belt, and the container storage device disclosed in Japanese Patent No. 4549257 discloses a container from below. It is the structure which supports directly or indirectly, and neither considers about the shaking of the container accommodated. Therefore, especially during exercise such as running, in addition to the shaking of the container storage unit body, the shaking of the container in the storage unit also becomes intense.

  The present invention has been made to solve the above-described problems. The main object of the present invention is to provide a waist bag that can suppress not only the shaking of the waist bag body during movement and exercise, but also the shaking of the container stored in the waist bag.

  The waist bag according to the present invention is provided so as to be along the wearer's pelvis located on both sides of the main body, the fixing device, the container storage having the opening provided in the main body, and the container storage. First and second fixing portions are provided. The container storage part includes a support part capable of supporting the outer periphery of the container, and a cover capable of receiving the container inside, the cover having an elastic part, and a low elastic part having lower elasticity than the low elastic part. Have

  It is preferable that the main body portion in the portion where the container storage portion is provided has higher rigidity than the cover. The stretchable portion may extend in the longitudinal direction of the main body so as to reach the other end from one end of the cover. The width of the opening of the container storage part can be wider than the width of the inside of the container storage part. Between the container storage part and the 1st and 2nd fixing | fixed part, the soft part which has a softness | flexibility rather than the main-body part in the part in which the container storage part was provided can be provided.

  Since the waist bag of the present invention includes a container storage portion including a support portion and a cover having an expansion / contraction portion and a low expansion / contraction portion, the container can be tightened and restrained, and the waist bag can be used during movement or exercise. The shaking of the container stored in can be suppressed. In addition, since the first and second fixing portions provided along the wearer's pelvis are provided, the waist bag body can be prevented from shaking during movement or exercise.

(Embodiment 1)
Embodiment 1 of the present invention will be described below. First, the configuration of the waist bag 1 according to Embodiment 1 will be described with reference to FIGS. As shown in FIGS. 1 and 2, the waist bag 1 according to the first embodiment includes a main body portion 3 including a container storage portion 5 and a fixture 2 for fixing to a wearer's body.

  Any material and structure can be adopted as the fixture 2 as long as it has a structure capable of fixing the waist bag 1 to the body of the wearer. In the example of FIGS. 1 and 2, the fixture 2 is configured by two belts extending from both sides of the main body 3 and connection parts provided on each of the belts.

  The main body 3 includes an opening 8 and a container storage 5 capable of storing a container, and first and second fixing portions 4a provided on both sides of the container storage 5 along the wearer's pelvis. , 4b.

  The container storage portion 5 includes a support portion 7 capable of supporting the outer periphery of the container and a cover 6 capable of receiving the container therein, and has an opening 8. As shown in FIG. 3, both the support portion 7 and the cover 6 are provided on the main body portion 3.

  A plurality of support portions 7 are provided, and when the container is accommodated between the support portion 7 and the cover 6, the outer surface of the container can be supported at a plurality of locations. Moreover, a container is restrained with the support part 7 and the cover 6, and when a waist bag 1 is mounted | worn, the shaking and rotation of a container can be suppressed. In the example of FIGS. 1 and 2, the support portion 7 and the cover 6 extend from one end in the longitudinal direction of the container storage portion 5 to reach the other end, but the support portion 7 and the cover 6 are attached. As long as it can be configured to be able to suppress the shaking and rotation of the container at the time, it may not be integrally formed in the longitudinal direction of the main body 3. By providing the container storage part 5 on the main body part 3 along the longitudinal direction of the main body part 3, the shaking of the container in the longitudinal direction can be suppressed.

  The support part 7 can adopt an arbitrary shape according to the shape of the container, and can be configured by an arbitrary number. In the example of FIGS. 1-3, it designed for the purpose of accommodating a cylindrical container, and the convex part is provided in two places. As a material of the support portion 7, any material having flexibility can be used, but polyethylene is adopted in the examples of FIGS.

  The cover 6 includes a stretchable portion 6a having stretchability, and a low stretchable portion 6b having lower stretchability than the stretchable portion 6a. Thereby, the cover 6 can tighten the outer periphery of the container. The elongation percentage of the low stretchable part 6b is preferably 10% or less. On the other hand, the expansion ratio of the stretchable part 6a is preferably 20% or more. Thereby, a container can be pressed with respect to the support part 7, and a container can be restrained. As a result, the shaking and rotation of the container when the waist bag 1 is attached can be reduced.

  The stretchable part 6 a preferably extends in the longitudinal direction of the main body so as to reach the other end from one end of the cover 6. In this case, the entire longitudinal direction of the cover 6 has a function of tightening the outer periphery of the container. 1 to 3, the cover 6 employs a configuration in which the stretchable portion 6a is sandwiched between the low stretchable portions 6b. However, the cover 6 includes the stretchable portion 6a and the low stretchable portion 6b. Any configuration can be selected as long as the shaking and rotation of the container can be reduced.

  As the material of the stretchable part 6a, any material having elasticity can be used, but in the examples of FIGS. 1 to 3, a power mesh fabric made of a synthetic material of 83% nylon and 17% polyurethane is employed. Yes. As the material of the low stretchable part 6b, any material that is less stretchable than the stretchable part 6a can be used, but in the example of FIGS. 1 to 3, polyester is employed.

  It is preferable that the main body 3 in the portion where the container storage 5 is provided has higher rigidity than the cover 6. Thereby, at the time of storing a container, it can suppress that the main-body part 3 in the part in which the container storage part 5 was provided deform | transforms along the shape of a container. That is, a large contact area between the wearer's wearing part and the main body part 3 of the waist bag 1 can be taken, and the waist bag 1 can suppress shaking and displacement of the waist bag 1. The waist bag 1 can be stabilized during movement and exercise, and does not hinder the movement of the wearer. As a material of the main body portion 3 in the portion where the container storage portion 5 is provided, any material having rigidity can be used, but in the example of FIGS. 1 to 3, a polyethylene plate is adopted.

  Although the container storage portion 5 has the opening 8, the width W <b> 1 of the opening 8 of the container storage portion 5 can be provided wider than the width W <b> 2 of the intermediate portion of the container storage portion 5. Here, the width of the container storage portion 5 is defined as the distance between the joint portions of the main body portion 3 and the cover 6. By making the width W1 of the opening 8 wider than the width W2 of the intermediate portion of the container storage portion 5, the container can be easily put in and out while having an effect of tightening the container inside the container storage portion 5. .

  The 1st and 2nd fixing | fixed part 4a, 4b is provided so that a wearer's pelvis may be followed. Thereby, since the main-body part 3 fits a wearer's body, the main-body part 3 can be firmly fixed to a wearer's body. This can also contribute to suppression of shaking of the waist bag 1 during exercise. In the example of FIGS. 1 and 2, the shape of the waist bag 1 is designed based on the shape of the pelvis. Since the shape of the pelvis differs between men and women, it is preferable that the shape of the waist bag 1 is different from that of the wearer.

  As a structure of the 1st and 2nd fixing | fixed part 4a, 4b which follows a wearer's pelvis, the structure caught on a wearer's pelvis and the structure which pinches | interposes a pelvis can be taken, for example. In order to prevent the waist bag 1 from being shaken or displaced in the longitudinal direction of the main body portion 3 and the direction perpendicular to the longitudinal direction, the first and second fixing portions 4a and 4b are provided with the pelvis. It is preferable to sandwich the structure. Moreover, the 1st and 2nd fixing | fixed part 4 may be comprised by two or more several site | parts, and may be provided with the raw material which has cushioning properties. As materials of the first and second fixing parts 4, urethane elastomers such as ether urethane elastomers and ester urethane elastomers, polystyrene elastomers, styrene-butadiene-styrene (SBS) elastomers, styrene-isoprene-styrene (SIS) Any material having cushioning properties such as styrene elastomers such as elastomers, olefin elastomers such as polyethylene elastomers and polypropylene elastomers, polyester elastomers or polyamide elastomers can be used. In the examples of FIGS. Is adopted.

  The main body part 3 on both sides of the container storage part 5 and between the first and second fixing parts 4a, 4b and the container storage part 5 is more than the main body part 3 in the part where the container storage part 5 is provided. Is also provided with a flexible soft part 9. More flexible than the main body 3 in the portion where the container storage portion 5 is provided in the connection portion between the main body portion 3 in the portion where the highly rigid container storage portion 5 is provided and the first and second fixing portions 4. By providing the soft part 9 to have, the compatibility with the waist bag 1 and the mounting site | part in a wearer can be improved more.

  In addition to the above flexibility, the soft part 9 may have more elasticity than the main body part 3 in the part where the container storage part 5 is provided. Thereby, the compatibility of the waist bag 1 and the mounting site | part in a wearer can further be improved. As the material of the soft part 9, for example, any material having elasticity such as polyurethane or rubber can be used. In the example of FIGS. 1 and 2, a polyester double raschel fabric is employed.

  With reference to FIG. 4, the example of mounting | wearing of the waist bag 1 which concerns on Embodiment 1 of this invention is shown. Specifically, FIG. 4 shows a state where the cylindrical container 10 is stored in the waist bag 1 and is mounted on the waist of the wearer.

  As shown in FIG. 4, since the rigidity of the main body 3 is higher than that of the cover 6, the main body 3 can be prevented from having a large curvature along the outer periphery of the container 10. Therefore, it is possible to avoid a state where the wearer's body and the main body 3 are in line contact, and the contact area can be increased. Thereby, the shake of the waist bag 1 accompanying the shake of the wearer's body, in particular, the shake in the direction perpendicular to the longitudinal direction of the main body 3 can be reduced, and the displacement of the waist bag 1 can be reduced. In addition, since the cover 6 has the expansion / contraction part 6a and the low expansion / contraction part 6b, the cover 6 can be brought into contact with the outer periphery of the container 10 and tightened. Thereby, the container can be pressed against the support portion 7 to deform the support portion 7, and the container 10 can be restrained by the cover 6 and the support portion 7. As a result, shaking and rotation of the container 10 can be suppressed.

  In addition, as a container which can accommodate the waist bag 1 which concerns on Embodiment 1 of this invention, the container which accommodated any one of three states, solid, liquid, and gas, and the container which accommodated the mixture may be sufficient. The shape of the container is not limited to a substantially cylindrical shape and can be applied by changing the shapes and configurations of the cover 6 and the support portion 7.

  As described above, the waist bag 1 according to the first embodiment has the rigidity of the main body portion 3 in the portion where the container storage portion 5 is provided in order to be able to suppress the shaking and displacement of the waist bag 1 itself. The first and second fixing portions 4 are provided so as to be higher than the cover 6 and further along the pelvis of the wearer. In addition, the waist bag 1 according to the first embodiment includes the support portion 7 and the cover 6 having the expansion / contraction portion 6a and the low expansion / contraction portion 6b in order to suppress the shaking and rotation of the container 10. It is configured to be tightened and restrained.

  Since the inventors of this application evaluated the shaking at the time of container accommodation in the waist bag 1 which concerns on Embodiment 1 of this invention, the result is demonstrated. The waist bag 1 shown in FIGS. 1-3 was prepared as an example of this invention. As a comparative example, a commercially available bottle pouch was prepared in which a support part was not formed, the entire container storage part was made of an elastic member, and the main body part in the part where the container storage part was provided did not have rigidity. The container used was a substantially cylindrical PET bottle containing 500 ml of liquid.

  A fixed point for measurement was determined for each point on the wearer's back and the cover of the waist bag 1, and the change in the distance between the two points was measured during running. Four subjects, two males and two females, run for 5 minutes, calculate the difference between the longest and shortest distances between two points in one step from the start of running for 3 minutes, and repeat this 5 times. The average value of 5 steps was calculated | required and evaluated as shaking of the waist bag 1.

  As a result of the evaluation, it was confirmed that the waist bag 1 according to Embodiment 1 of the present invention was able to suppress the shaking to be smaller than that of the comparative example, with 3 out of 4 subjects. In addition, about one person, the difference of the shake of this invention example and a comparative example was not able to be confirmed, but since the difference of the shake was confirmed about 3 persons among 4 persons, the example of this invention is more than a comparative example. It can be said that shaking can be suppressed.

  Moreover, the inventors of this application evaluated the effect which the rigidity of the main-body part in the part in which the container accommodating part was provided with respect to the shake in the waist bag 1 which concerns on Embodiment 1 of this invention. As an example of the present invention, two waist bags 1 shown in FIGS. 1 to 3 were prepared, which differed only in the thickness of the polyethylene plate constituting the main body portion in the portion where the container storage portion was provided. Specifically, two types of polyethylene plates having a thickness of 1.0 mm and 1.5 mm were prepared.

  The rigidity of the polyethylene plate was measured with a Gurley tester under the conditions of a distance between the load mounting hole and the fulcrum of 100 mm, a weight of 200 g, a test piece length of 25 mm, and a test piece width of 6 mm. When the bending resistance index value was 1.3 mN and the polyethylene plate thickness was 1.5 mm, the bending resistance index value was 4.6 mN. Further, in the present invention example, the radius of curvature of the polyethylene plate constituting the main body portion in the portion where the container storage portion is provided when a substantially cylindrical PET bottle (about 70 mm in diameter) is stored as a container is measured with an R ruler. The elongation ratio of the stretchable part of the cover was measured by an autograph. As a result, when the thickness of the polyethylene plate is 1.0 mm, the radius of curvature R is 100 mm, and the stretch rate of the stretchable portion is 20 to 30%. When the thickness of the polyethylene plate is 1.5 mm, the radius of curvature R is 150 mm and the stretchable portion. The elongation percentage was 20 to 50%. As a comparative example, the support portion is not formed, the entire container housing portion is made of a non-stretchable member, and the main body portion in the portion where the container housing portion is provided has a commercially available bottle pouch and a support portion. However, the whole container accommodating part consisted of an elastic member, and the main body part in the part in which the container accommodating part was provided prepared the commercial bottle pouch which does not have rigidity.

  The evaluation method of shaking is the same method as in the first embodiment. Three male subjects, three males and three females, run for 5 minutes and calculate the difference between the longest and shortest distances between two points in one step from the start of running for 3 minutes. Repeated 3 times, the average value of 3 steps was calculated and evaluated as shaking.

  As a result of the evaluation, the waist bag 1 according to the first embodiment of the present invention is able to suppress shaking generally as compared with the comparative example by three of the three test subjects, and particularly when the polyethylene plate is as thick as 1.5 mm. It was confirmed that the suppressing effect was great. By thickening the polyethylene plate, it is possible to suppress the curvature of the main body portion in the portion where the container storage portion is provided during container storage, to increase the contact area with the body of the wearer, and to suppress the shaking of the waist bag 1. It can be said.

  As described above, the embodiment of the present invention has been described. However, the embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The waist bag of the present invention is particularly advantageously applied to a waist bag that can be carried by storing a container during movement or exercise.
