[0009] Hereinafter, preferred embodiments will be described in detail with appropriate reference to the drawings.

[0010] (Overall composition of a golf club bag) First, the overall structure of the golf club bag 100 according to the embodiment will be described. Figure 1 1 is a side view of the golf club bag 100. In the golf club bag 100, Figure 1 The left side of the paper is the front side, Figure 1 The right side of the paper is the back side. The golf club bag 100 is a bag for storing golf clubs, etc. Figure 1 Hereinafter, the upper side of the golf club bag 100 in the self-standing state is simply referred to as "upper side", and the lower side is simply referred to as "lower side".

[0011] like Figure 1 As shown, the golf club bag 100 according to the present embodiment includes an outer bag body 10, a bottom portion 20, and a core member 30. These components will be described in order below.

[0012] <Outer bag body> The outer bag body 10 is a cylindrical part that forms the outer contour of the golf club bag 100. The outer bag body 10 is formed of, for example, synthetic leather, but the material of the outer bag body 10 is not limited. The outer bag body 10 includes an opening frame 11 located at the upper part, a handle 12 located at the upper part of the front, a front bag 13 located at the lower part of the front and protruding outward, and a back bag 14 located from the center part to the lower part in the vertical direction of the back and protruding outward. In addition, the back bag 14 may be located only at the lower part of the back.

[0013] The opening frame 11 is a portion corresponding to an insertion port for inserting golf clubs into the golf club bag 100. The handle 12 is a member for picking up the golf club bag 100. The front pocket 13 and the back pocket 14 are both storage portions for storing small items, etc. As described above, the handle 12 and the front pocket 13 are located in front of the outer bag body 10, and the back pocket 14 is located on the back of the outer bag body 10. That is, the back pocket 14 is located on the opposite side of the handle 12 and the front pocket 13, sandwiching the center of the outer bag body 10.

[0014] <Bottom> The bottom portion 20 is a member provided at the lower end portion of the outer bag body 10, and is located at the lower end portion of the golf club bag 100. The bottom portion 20 blocks the lower end of the outer bag body 10, and contacts the ground when the golf club bag 100 is in a self-standing state. Figure 2 3 is a side view of the bottom 20 and the core material 30. Figure 2 As shown, the bottom 20 of this embodiment includes: a circular bottom surface 21, and an annular peripheral wall 22 extending upward from the peripheral edge of the bottom surface 21. The bottom 20 is more rigid than the outer bag body 10 and the core material 30, for example, formed of a hard resin. The material of the bottom 20 is not limited.

[0015] <Core material> The core material 30 is a component located on the inner side of the outer bag body 10. The core material 30 has a substantially cylindrical shape and extends in the up-down direction. The lower end portion of the core material 30 is mounted on the bottom 20, and the upper end portion is mounted on the opening frame 11 of the outer bag body 10. The core material 30 is formed of a material that is softer than the bottom 20. Therefore, the core material 30 is less rigid than the bottom 20 and is easy to bend. After investigating the previous products that have been used, the applicant determined that although the core material 30 is easy to bend, it may undergo plastic deformation.

[0016] To suppress the plastic deformation of the core material 30, it is possible to increase the thickness of the core material 30. However, in this case, the weight of the core material 30 increases, and the weight of the golf club bag 100 increases. For example, the core material 30 of the present embodiment is designed to have a total weight of, for example, less than 700 g. Therefore, the thickness of the core material 30 has to be set small. Therefore, in the core material 30 of the present embodiment, by providing a reinforcing component in the core material 30 and arranging the reinforcing component in an appropriate range, the strength of the golf club bag 100 is ensured while achieving lightweight.

[0017] (Core material details) Next, the structure of the core material 30 will be described in detail. Figure 3 yes Figure 2 The III-III cross-sectional view. Figure 2 and Figure 3As shown in FIG. 1 , the core material 30 includes a core material body 31, longitudinal reinforcing members 32a to 32e, and a transverse reinforcing member 33. These components will be described in order below.

[0018] <Core material body> The core material body 31 is a component that becomes the basis of the core material 30. The lower end portion of the core material body 31 is mounted on the outer peripheral wall 22 of the bottom 20. The core material body 31 has a substantially cylindrical shape and extends in the up-down direction. In addition, the up-down dimension of the core material body 31 is, for example, 80 cm to 100 cm. As mentioned above, the core material 30 of the present embodiment is designed to have a total weight of, for example, less than 700 g. Therefore, the thickness of the core material body 31 is set to, for example, less than 1.2 mm. In the present embodiment, the thickness of the core material body 31 is, for example, 0.5 mm to 1.2 mm. In addition, the core material body 31 of the present embodiment is formed of resin. Among them, the material of the core material body 31 is not limited.

[0019] <Vertical reinforcement components> The longitudinal reinforcing members 32a to 32e are strip-shaped reinforcing members extending in the vertical direction. The longitudinal reinforcing members 32a to 32e are arranged on the outer peripheral surface of the core material body 31 and extend upward from the bottom 20. In the present embodiment, the longitudinal reinforcing members 32a to 32e are sewn to the core material body 31, but they can also be bonded to the core material body 31 by adhesives or the like. The lower ends of the longitudinal reinforcing members 32a to 32e are located near the bottom 20, and the upper ends are located at a position 20 cm to 40 cm upward from the bottom (i.e., 30% to 50% of the vertical dimension of the core material body 31). Moreover, the vertical dimension of the longitudinal reinforcing members 32a to 32e of the present embodiment is approximately 20 cm to 40 cm.

[0020] Here, the applicant investigated the previous products and existing products used by users and found that: in the core material 30, plastic deformation is easily generated in the range of 10 cm to 30 cm above the bottom 20 (hereinafter referred to as the "deformation generation range"). This is considered to be because the core material 30 is fixed to the bottom 20, so when an external force is applied to the side of the core material 30, the load is concentrated on the portion slightly above the bottom 20 of the core material 30, that is, the deformation generation range.

[0021] As described above, the longitudinal reinforcing members 32a to 32e of the present embodiment are located within the range including the above-mentioned deformation generation range, so that the plastic deformation generated in the core material 30 can be suppressed. In addition, the vertical dimension of the longitudinal reinforcing members 32a to 32e of the present embodiment is approximately 20 cm to 40 cm as described above, which is smaller than the vertical dimension of the core material body 31. Moreover, the longitudinal reinforcing members 32a to 32e of the present embodiment are arranged at intervals in the circumferential direction. Therefore, according to the present embodiment, the total weight of the core material 30 can be suppressed, and the golf club bag 100 can be made lightweight.

[0022] In addition, the width dimension of the longitudinal reinforcing members 32a to 32e, that is, the dimension along the circumferential direction of the core material body 31, is 5 cm to 10 cm. In addition, the thickness of the longitudinal reinforcing members 32a to 32e is 0.2 mm to 1.0 mm. Furthermore, the longitudinal reinforcing members 32a to 32e are formed of the same material as the core material body 31. However, the longitudinal reinforcing members 32a to 32e may also be formed of a material different from that of the core material body 31.

[0023] In addition, the core material 30 of this embodiment has five longitudinal reinforcing members 32a to 32e. The five longitudinal reinforcing members 32a to 32e include the first longitudinal reinforcing member 32a. Figure 3 As shown, the direction of the width center (circumferential center) of the back bag 14 when viewed from above is defined as the first angular direction A, with the axis 34 of the core body 31 as the reference.

[0024] The applicant investigated the conventional products that have been used and found that the back side of the core material 30 is particularly susceptible to plastic deformation in the deformation range described above. This is considered to be because the back bag 14 of the outer bag body 10 protrudes outward, and when the golf club bag 100 is carried, for example, the back bag 14 contacts a wall, etc., and an impact is easily applied to the back side of the core material 30 through the back bag 14. In addition, it is considered that the front bag 13 also protrudes outward, but the protrusion of the front bag 13 is greater than that of the back bag 14, so that the impact is easily absorbed inside compared with the back bag 14, and therefore the front side of the core material 30 is less susceptible to plastic deformation than the back side.

[0025] As described above, the first longitudinal reinforcing member 32a of the present embodiment is located in the first angular direction A on the back side corresponding to the deformation occurrence range of the core material 30. Therefore, according to the present embodiment, plastic deformation occurring in the core material 30 can be effectively suppressed.

[0026] In addition, the longitudinal reinforcing members 32a to 32e include the second longitudinal reinforcing member 32b. Figure 3 As shown, when the axis 34 of the core material body 31 is used as a reference, the angular direction that is offset by an angle X of 72 degrees clockwise from the first angular direction A when viewed from above is set as the second angular direction B. In this way, the second longitudinal reinforcing member 32b is located in the second angular direction B. The offset angle X only needs to be within 90 degrees.

[0027] Furthermore, the longitudinal reinforcing members 32a to 32e include a third longitudinal reinforcing member 32c. Figure 3As shown, when the axis 34 of the core material body 31 is used as a reference, the angular direction offset by an angle Y of 72 degrees counterclockwise from the first angular direction A when viewed from above is set as the third angular direction C. In this way, the third longitudinal reinforcing member 32c is located in the third angular direction C. The offset angle Y only needs to be within 90 degrees.

[0028] As described above, the core material 30 of the present embodiment has, in addition to the first longitudinal reinforcing member 32a, the second longitudinal reinforcing member 32b and the third longitudinal reinforcing member 32c. Therefore, even if a force is applied from the back side of the above-mentioned deformation generation range and the core material 30 is deformed, the deformation amount of the core material 30 can be suppressed to such an extent that the second longitudinal reinforcing member 32b and the third longitudinal reinforcing member 32c do not cause plastic deformation in the core material 30.

[0029] Furthermore, the longitudinal reinforcing members 32a to 32e include a fourth longitudinal reinforcing member 32d and a fifth longitudinal reinforcing member 32e. The fourth longitudinal reinforcing member 32d is located in an angular direction offset by an angle X of 144 degrees clockwise from the first angular direction A, that is, in the fourth angular direction D. In addition, the fifth longitudinal reinforcing member 32e is located in an angular direction offset by an angle Y of 144 degrees counterclockwise from the first angular direction A, that is, in the fifth angular direction E. Moreover, in the present embodiment, the longitudinal reinforcing members 32a to 32e are arranged at equal intervals in the circumferential direction.

[0030] Thus, in the present embodiment, the longitudinal reinforcing members 32a to 32e are arranged at equal intervals around the entire circumference of the core material body 31, so that the rigidity of the deformation generation range in the core material 30 can be improved, thereby suppressing the plastic deformation in the deformation generation range. In order to further reduce the weight of the core material 30, the fourth longitudinal reinforcing member 32d and the fifth longitudinal reinforcing member 32e can be omitted, and further, not only the fourth longitudinal reinforcing member 32d and the fifth longitudinal reinforcing member 32e can be omitted, but also the second longitudinal reinforcing member 32b and the third longitudinal reinforcing member 32c can be omitted.

[0031] <Horizontal reinforcement parts> The lateral reinforcing member 33 is a belt-shaped and annular member extending in the circumferential direction of the core material body 31. Figure 2As shown, the transverse reinforcement member 33 is provided on the outer peripheral surface of the core material body 31 and is combined with the upper end portions of the longitudinal reinforcement members 32a to 32e. Therefore, the transverse reinforcement member 33 can suppress the displacement of the upper end portions of the longitudinal reinforcement members 32a to 32e. As a result, the rigidity of the area below the transverse reinforcement member 33 of the core material 30 can be improved. As a result, the rigidity of the deformation generation range in the core material 30 is improved, and the plastic deformation generated in the core material 30 can be suppressed. In the present embodiment, the transverse reinforcement member 33 is sewn to the core material body 31 and the longitudinal reinforcement members 32a to 32e, but it can also be bonded to the longitudinal reinforcement members 32a to 32e and the core material body 31 by an adhesive or the like.

[0032] In addition, the width dimension of the transverse reinforcing member 33, that is, the dimension in the vertical direction, is 5 cm to 10 cm. In addition, the thickness of the transverse reinforcing member 33 is 0.2 mm to 1.0 mm. Furthermore, in this embodiment, the transverse reinforcing member 33 is formed of the same material as the core body 31 and the longitudinal reinforcing members 32a to 32e. Among them, the transverse reinforcing member 33 can also be formed of a different material from the core body 31 and the longitudinal reinforcing members 32a to 32e.

[0033] In addition, in the present embodiment, the ratio of the longitudinal reinforcing members 32a to 32e and the transverse reinforcing member 33 in the outer peripheral surface of the core body 31 is less than 20%. That is, the ratio of the portion corresponding to the exposed portion without the reinforcing member in the outer peripheral surface of the core body 31 is more than 80%. Therefore, the weight of the core 30 can be suppressed, and the weight of the golf club bag 100 can be suppressed.
