Description

[Technical field]

[0001] The present invention relates to a golf bag. [Background technology]

[0002] A caddy bag has a bottom part that corresponds to the bottom portion. The bottom part needs to have a certain level of rigidity. If the bottom part has a high rigidity, deformation of the bottom part is suppressed, and the caddy bag can be prevented from tipping over. As a method for increasing the rigidity of the bottom part, a method of making the bottom part have a multi-layer structure has been proposed (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2008-23242 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, if the bottom part has a multi-layer structure, the manufacturing process becomes complicated and the weight increases.

[0005] In view of the above circumstances, an object of the present invention is to provide a caddy bag having a bottom part that is highly rigid, easy to manufacture, and lightweight. [Means for solving the problem]

[0006] A caddy bag according to one embodiment of the present invention comprises a cylindrical bag body for accommodating golf clubs, and a bottom part attached to the lower end of the bag body, the bottom part having a bottom surface portion and an annular outer peripheral portion arranged to surround the bottom surface portion and formed integrally with the bottom surface portion, the outer peripheral portion including an annular inclined portion that slopes upwardly as it moves away from the bottom surface portion, and the inclined portion has a plurality of legs formed thereon that are recessed outward.

[0007] In this configuration, the inclined portion of the outer periphery is formed with a plurality of legs recessed outward. By forming the recessed portions on the inclined portion in this manner, the rigidity of the portion in the vertical and horizontal directions can be increased. Furthermore, since the rigidity of the bottom part can be increased in the above configuration, it is not necessary for the bottom part to have a multi-layer structure. As a result, the bottom part can be easily manufactured and can be made lighter. Moreover, by making the recessed portions on the outside into legs, it is not necessary to manufacture and attach the legs separately. This also makes it possible to easily manufacture the bottom part.

[0008] In the above caddy bag, the plurality of legs may be formed at equal intervals in the circumferential direction.

[0009] In this configuration, since the multiple legs are formed at equal intervals in the circumferential direction, the rigidity of the bottom part can be increased around the entire circumference.

[0010] In the above-mentioned caddy bag, the bottom portion may be raised so as to become higher toward the center.

[0011] In this configuration, the bottom part is raised so that it becomes higher toward the center. Therefore, for example, when a force is applied to the bottom part from above, a compressive load that is less likely to cause deformation than a tensile load is applied to the bottom part. This increases the rigidity of the bottom part.

[0012] In the above-mentioned caddy bag, the raised height of the bottom surface portion may be 10 mm or more and 30 mm or less.

[0013] In this configuration, the bottom part has a raised height of 10 mm or more, so that the bottom part can have high rigidity. Also, the bottom part has a raised height of 30 mm or less, so that the storage area of ​​the golf bag can be prevented from being compressed.

[0014] In the above-mentioned caddy bag, the outer periphery may include an annular upright wall portion extending in the vertical direction.

[0015] In this configuration, the outer periphery includes an annular vertical wall extending in the vertical direction, which makes it difficult for the housing to deform in the vertical direction and increases rigidity against torsion around a horizontal axis, for example. Effect of the Invention

[0016] According to the above configuration, it is possible to provide a caddy bag having a bottom part that is easy to manufacture, has high rigidity, and is lightweight. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] (Overview of the caddy bag) A caddy bag 100 according to one embodiment of the present invention will be described below. First, an overview of the caddy bag 100 will be described. Fig. 1 is a schematic diagram of the caddy bag 100. The caddy bag 100 includes a cylindrical bag body 10 that accommodates a golf club 101, and a bottom part 20 attached to the lower end of the bag body 10.

[0019] The material of the bag body 10 is not particularly limited, but for example, the bag body 10 can be formed by covering a resin core with a cloth cover. The bottom part 20 in this embodiment is made of resin. The bottom part 20 is fixed to the lower end of the bag body 10. For example, the bottom part 20 may be fixed to the bag body 10 by bonding with an adhesive and sewing. In the caddy bag 100, if the bottom part 20 has a high rigidity, the bottom part 20 is less likely to deform, and as a result, the caddy bag 100 can be prevented from tipping over.

[0020] (Bottom part details) Next, the bottom part 20 will be described in detail. Fig. 2 is a perspective view of the bottom part 20 as viewed from the top side. Fig. 3 is a perspective view of the bottom part 20 as viewed from the bottom side. As shown in Figs. 2 and 3, the bottom part 20 includes a bottom surface portion 30 and an outer peripheral portion 40. Below, these components will be described in order.

[0021] <Bottom part> The bottom surface portion 30 is located at the center of the bottom part 20. In this embodiment, the bottom surface portion 30 is raised so as to become higher from the outer periphery toward the central portion 31. In other words, the bottom surface portion 30 is formed in a dome shape as a whole. Therefore, for example, when a force is applied to the bottom surface portion 30 from above, a compressive load that is less likely to cause deformation than a tensile load is applied to the bottom surface portion 30. Therefore, by raising the bottom surface portion 30 as in this embodiment, the rigidity of the entire bottom part 20 can be increased.

[0022] Describing the bottom portion 30 in more detail, the bottom portion 30 includes a central portion 31 and a raised portion 32 .

[0023] The central portion 31 is a portion that includes the center point of the bottom surface portion 30 in a plan view. In this embodiment, the central portion 31 is formed in a horizontal plane. However, the central portion 31 may be formed in a partially spherical shape.

[0024] The raised portion 32 is an annular portion disposed so as to surround the entire circumference of the central portion 31. The raised portion 32 is formed so that its height increases from the outer circumferential edge toward the central portion 31. In this embodiment, the raised portion 32 is formed in a curved surface. Furthermore, the raised portion 32 is formed with a plurality of downwardly convex valley portions 33. Each valley portion 33 extends linearly from the central portion 31 toward the outer circumferential edge.

[0025] However, the raised portion 32 may have a peak portion that is convex upward instead of or in addition to the valley portion 33. In either case of the valley portion 33 or the peak portion, an inflection portion 34 where the cross section changes from concave to convex is formed around the valley portion 33. The periphery of such an inflection portion 34 can function as a beam or pillar in the bottom surface portion 30. Therefore, by including the inflection portion 34 in the bottom surface portion 30 as in this embodiment, the rigidity of the bottom part 20 can be increased.

[0026] Furthermore, each valley portion 33 is curved in a plan view. Specifically, each valley portion 33 is curved such that the circumferential position changes toward the outer circumferential edge of the bottom surface portion 30. As a result, inflection portions 34 are formed over a wide range of the bottom surface portion 30, and the rigidity of the bottom part 20 can be further increased. Although each valley portion 33 appears on the underside of the bottom surface portion 30, each valley portion 33 may be visible when the caddy bag 100 is transported. Therefore, curving each valley portion 33 is also preferable from the viewpoint of design.

[0027] 3, a plurality of reinforcing parts (ribs) 35 having a thickness greater than that of other adjacent parts are formed on the lower surface side of the bottom surface part 30. The reinforcing parts 35 in this embodiment are formed in a ring shape along the outer peripheral edge of the central part 31, and are formed in a line shape extending from the central part 31 toward the outer peripheral edge of the bottom surface part 30. The reinforcing parts 35 extending from the central part 31 toward the outer peripheral edge of the bottom surface part 30 are formed in threes at each part corresponding to the gap between adjacent valley parts 33. The reinforcing parts 35 extending from the central part 31 toward the outer peripheral edge of the bottom surface part 30 can suppress deformation of the bottom surface part 30 in the up-down direction, and therefore the rigidity of the bottom part 20 can be further increased.

[0028] Furthermore, the reinforcing portion 35 is formed so as to protrude downward from the lower surface of the bottom portion 30. Therefore, when the caddy bag 100 is viewed from below, the reinforcing portion 35 can be seen. Therefore, forming the reinforcing portion 35 so as to protrude downward from the lower surface of the bottom portion 30 as in this embodiment is preferable from the viewpoint of design. However, the reinforcing portion 35 may be formed so as to protrude upward from the upper surface of the bottom portion 30. The shape of the reinforcing portion 35 is not limited to the above. For example, the reinforcing portion 35 may be formed in a honeycomb shape.

[0029] The protruding height (height difference) h of the bottom surface portion 30 is not particularly limited, but is desirably 10 mm or more and 30 mm or less (see FIG. 4). By making the protruding height h of the bottom surface portion 30 10 mm or more, high rigidity of the bottom part 20 can be ensured. On the other hand, by making the protruding height h of the bottom surface portion 30 30 mm or less, compression of the storage area of ​​the caddy bag 100 can be suppressed.

[0030] <Outer periphery> The outer peripheral portion 40 is disposed so as to surround the bottom surface portion 30. In this embodiment, the outer peripheral portion 40 is annular and formed integrally with the bottom surface portion 30. As described above, the bottom surface portion 30 in this embodiment is raised so as to become higher toward the central portion 31. Therefore, when a force is applied to the bottom surface portion 30 from above, the bottom surface portion 30 tends to deform so as to spread outward. However, since the outer peripheral portion 40 formed integrally with the bottom surface portion 30 is annular and surrounds the entire circumference of the bottom surface portion 30, deformation of the bottom surface portion 30 is suppressed. As a result, the rigidity of the bottom part 20 can be further increased.

[0031] To explain the outer periphery 40 in more detail, as shown in FIG. 2, the outer periphery 40 includes a horizontal portion 41, an inclined portion 42, and a standing wall portion 43.

[0032] The horizontal portion 41 is located outside the bottom portion 30 and is a portion that continues from the bottom portion 30. The horizontal portion 41 is formed in an annular shape and surrounds the bottom portion 30. The horizontal portion 41 is formed perpendicular to the vertical direction (i.e., horizontal). Therefore, the horizontal portion 41 is not easily deformed by a force applied in the horizontal direction. Therefore, the outer peripheral portion 40 including the horizontal portion 41 can efficiently suppress deformation of the bottom portion 30 in the horizontal direction. However, the horizontal portion 41 may be omitted from the outer peripheral portion 40, or the horizontal portion 41 may be inclined so as to become lower toward the outside.

[0033] The inclined portion 42 is located outside the horizontal portion 41 and is a portion that continues from the horizontal portion 41. The inclined portion 42 is formed in a ring shape and surrounds the horizontal portion 41. The inclined portion 42 is inclined so that it becomes higher toward the outside (as it moves away from the bottom surface portion 30). The inclination angle α of the inclined portion 42 is not particularly limited, but is desirably equal to or greater than 30 degrees and equal to or less than 60 degrees (see FIG. 4).

[0034] In addition, a plurality of legs 44 are formed at equal intervals in the circumferential direction on the inclined portion 42. FIG. 4 is a vertical cross-sectional view of the bottom part 20 in a portion not including the legs 44. FIG. 5 is a vertical cross-sectional view of the bottom part 20 in a portion including the legs 44. As can be seen by comparing FIG. 4 and FIG. 5, the legs 44 are recessed outward, and their tips are located lower than the horizontal portion 41 and are in contact with the ground (grounded). However, the tips of the legs 44 may be located at the same height as the horizontal portion 41. By forming the legs 44 on the inclined portion 42 as in this embodiment, the vertical and horizontal rigidity of the portion corresponding to the legs 44 is increased. Moreover, by making the recessed portions on the outside of the inclined portion 42 the legs 44, there is no need to manufacture and attach the legs 44 separately.

[0035] The standing wall portion 43 extends upward from the inclined portion 42 and is a portion that is continuous with the inclined portion 42. The standing wall portion 43 is formed in an annular shape and extends in the up-down direction. This standing wall portion 43 is fixed to the lower end portion of the bag body 10. Since the outer peripheral portion 40 includes the standing wall portion 43 that extends in the up-down direction, it is difficult for the outer peripheral portion 40 to deform in the up-down direction, and it is possible to increase rigidity against twisting around a horizontal axis, for example.

[0036] As shown in Figs. 4 and 5, the bottom part 20 of this embodiment has a substantially constant overall thickness, except for the reinforcing portion 35, and is thin. The bottom part 20 of this embodiment is formed to have a thickness of 0.8 mm or more and 2.0 mm or less. Furthermore, the bottom part 20 of this embodiment can ensure sufficient rigidity, so there is no need for a multi-layer structure. Therefore, the bottom part 20 of this embodiment can be made lighter. The bottom part 20 of this embodiment is formed to have a weight of 80 g or more and 150 g or less. Furthermore, the bottom part 20 of this embodiment can be manufactured easily, for example, by simple injection molding.

[0037] (Modification) The caddy bag 100 described above includes the bottom part 20 shown in Fig. 2, but the caddy bag 100 may also include a bottom part 20A shown in Fig. 6. Fig. 6 is a perspective view of the bottom part 20A in a modified example, viewed from the top side. The bottom part 20A in the modified example differs from the bottom part 20 described above in the shape of the bottom surface portion 30, but is otherwise the same as the bottom part 20 described above.

[0038] In the bottom part 20A of the modified example, the bottom surface portion 30 also rises higher toward the central portion 31. However, the bottom surface portion 30 is formed in a stepped shape. In other words, the bottom surface portion 30 is formed so that annular portions extending vertically from the central portion 31 outward and annular portions extending horizontally are alternately continuous. The boundaries between these portions are bent in cross section. In other words, the bottom surface portion 30 shown in FIG. 6 has multiple bent portions 36 where the cross section is bent.

[0039] The bent portion 36 can function as a beam or pillar around its periphery, similar to the inflection portion 34 (see FIG. 2). Therefore, the rigidity of the bottom part 20A shown in FIG. 6 can also be increased. Furthermore, since the bottom part 20A can ensure sufficient rigidity, it does not need to have a multi-layer structure, making it easy to manufacture and lightweight.

[0040] Although the bottom parts 20 and 20A described above are formed to have a circular shape in a plan view, the shape of the bottom parts 20 and 20A is not limited to this. For example, the bottom parts 20 and 20A may have an elliptical shape or a rectangular shape in a plan view.

[0041] Also, a part of the configuration of the bottom part 20A shown in Fig. 6 may be applied to the bottom part 20 shown in Fig. 2. That is, the bottom part 20 may include both the inflection portion 34 and the bent portion 36. Furthermore, the bottom part 20 may be formed so that there is no portion whose cross section is concave over the entirety and so that it does not include either the inflection portion 34 or the bent portion 36.
