  The present invention relates to a golf bag (caddy bag) for housing a golf club and a method for manufacturing the same, and more particularly to a golf bag having a core inserted into a main body and a method for manufacturing the same.

  2. Description of the Related Art A member that reinforces a body portion of a golf bag that houses a golf club is conventionally known.

  For example, Japanese Patent Application Laid-Open No. 2003-52877 (Patent Document 1) discloses that three elastic resin shafts are provided at a position connecting a mouth frame portion and a bottom portion of a golf bag.

  Further, in Japanese Patent Application Laid-Open No. 2005-192666 (Patent Document 2), a plurality of frames connecting the mouth frame and the bottom frame of a golf bag are bent into a dome shape inside the back bag portion of the outer shell of the golf bag. While passing.

  In order to reduce the weight of the golf bag, it is required to form a thin core material to be inserted into the main body. When the core material is thinly formed, the core material is likely to be deformed. Therefore, it is required to perform reinforcement for suppressing the deformation of the core material while suppressing an increase in weight.

  In a general golf bag, a handle for a user to hold is provided slightly above the position of the center of gravity of the golf bag. In a general golf bag having a core material height of about 850 mm to 900 mm, the center of gravity is located at the upper part of the core material (approximately 3/4 of the total core material height). Therefore, it is particularly required to reinforce the upper part of the core material in the front surface portion where the handle is provided.

  Further, when the golf club is lowered to the ground, the bottom portion on the back surface side facing the handle is grounded first, so that this portion is likely to be deformed. Therefore, it is particularly required to reinforce the bottom side of the golf bag at the back surface of the golf bag.

  In addition, when storing the golf bag in the trunk of the car, etc., the golf bag will be laid sideways and placed, but at this time, in the side part located between the front part and the back part, Deformation is likely to occur at the center in the height direction due to the force from above. For this reason, in the side part of a golf bag, it is calculated | required especially to reinforce the center part of a height direction.

  As described above, in the front portion, the back portion, and the side portion of the golf bag, the portions that should be reinforced are different. Therefore, in order to suppress the deformation of the golf bag while suppressing the increase in weight, it is required to selectively reinforce a specific portion for each of the front surface portion, the back surface portion, and the side surface portion of the golf bag. However, from this viewpoint, it cannot be said that the golf bags described in Patent Documents 1 to 3 have a sufficient configuration.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a golf bag and a method for manufacturing the same that are light in weight and have suppressed deformation of each part.

  The golf bag according to the present invention is a golf bag having a front surface provided with a handle, a back surface facing the front surface, and first and second side surfaces positioned between the front surface and the back surface and facing each other. And comprising a main body, a cylindrical core material inserted into the main body, and a linear or belt-shaped reinforcing material continuously provided on the peripheral surface of the core material, From the bottom, it passes through the central portion of the first side surface portion in the height direction of the core material, and then passes through the portion of the front surface portion located above the center of the core material in the height direction, and then the second side surface It is provided so as to pass through the central portion of the core in the height direction of the core and reach the bottom of the back surface.

  According to the above configuration, the reinforcing material is provided in the above-described path, so that the core material can be selectively reinforced at portions particularly required in the front surface portion, the back surface portion, and the side surface portion of the golf bag. Therefore, the core material can be formed thin while suppressing the use amount of the reinforcing material. As a result, the deformation of the golf bag can be suppressed while reducing the weight.

  Preferably, the golf bag further includes a shoulder belt attached to the front surface portion, and one end portion of the shoulder belt is attached to a mouth frame portion provided at an upper end portion of the core material in the front surface portion, and the other end of the shoulder belt. The part is attached in the vicinity of the center in the height direction of the core material in the front part.

  In the above configuration, the “center portion” in the height direction of the core material is a portion located between 1/3 and 2/3 of the total height of the core material (that is, the core material is divided into three equal parts in the height direction). Means the part located in the center. Further, the “back surface portion” means a range from a position facing the handle in the radial direction to a position rotated by 60 ° left and right around the center of the core material. Further, the “near the center” in the height direction of the core material means a portion located between 3/8 to 5/8 of the total height of the core material.

  The reinforcing material attached to the core material is typically provided on the outer peripheral surface of the core material, but may be provided on the inner peripheral surface of the core material.

  As one example, in the golf bag, the reinforcing material includes a plurality of reinforcing materials provided so as to extend in substantially the same direction. For example, two reinforcing members are provided, but only one reinforcing member may be provided, or three or more reinforcing members may be provided.

  A golf bag manufacturing method according to the present invention is a method for manufacturing the above-described golf bag, the step of attaching the reinforcing material in an arch shape to the sheet material included in the core material, and the sheet material to which the reinforcing material is attached. And rolling to form a cylindrical core material.

  According to the present invention, it is possible to provide a golf bag and a method for manufacturing the same, which are lightweight and suppressed in deformation of each part.

  Embodiments of the present invention will be described below. Note that the same or corresponding portions are denoted by the same reference numerals, and the description thereof may not be repeated.

  Note that in the embodiments described below, when referring to the number, amount, and the like, the scope of the present invention is not necessarily limited to the number, amount, and the like unless otherwise specified. In the following embodiments, each component is not necessarily essential for the present invention unless otherwise specified.

  First, the basic configuration of the golf bag 1 according to the present embodiment will be described with reference to FIGS. With reference to FIGS. 1 to 3, golf bag 1 according to the present embodiment includes a main body 100, a cylindrical core material 200 provided inside main body 100, and a reinforcement attached to the peripheral surface of core material 200. The material 300 includes a handle 400 and a shoulder belt 500.

  The main body 100 is made of leather including, for example, polyurethane. The core material 200 includes a sheet material having a weight per 10 cm × 10 cm (planar dimension) made of, for example, polypropylene, polyethylene, foamed polypropylene, foamed polyethylene, or the like. Note that the thickness of the core material 200 is appropriately changed depending on factors such as whether the material is a solid material or a foam material. The core member 200 has a mouth frame part 210 and a bottom frame part 220 at both ends in the height direction. The mouth frame portion 210 and the bottom frame portion 220 are portions that are reinforced to the sheet material and are relatively difficult to deform.

  The reinforcing material 300 is provided on the outer peripheral surface of the core material 200. In the present embodiment, the reinforcing member 300 includes two linear reinforcing members 310 and 320. As the linear reinforcement members 310 and 320, for example, a wire having a diameter of about 1 to 3 mm, a piano wire, a fiber reinforced resin, or the like can be used. In a typical example, the reinforcing materials 310 and 320 are sewn or bonded to the surface of the sheet material constituting the core material 220. When the reinforcing members 310 and 320 are sewn to the sheet material, for example, the reinforcing material is inserted into the tubular fabric, and the fabric and the sheet are placed so that the sewn portion sandwiches the reinforcing material over the entire longitudinal direction of the reinforcing material. Sew the material together. In this manner, the position of the reinforcing material on the sheet material is fixed by sandwiching the reinforcing materials 310 and 320 at the sewn portion. Note that, instead of the above-described fixing by sewing, it is also conceivable to fix the reinforcing material to the sheet material by adhesion.

  Moreover, it is also possible to use a belt-shaped reinforcing material instead of the linear reinforcing material. As the belt-shaped reinforcing material, for example, a metal plate, a resin plate, or a fiber reinforced resin plate having a width of about 5 to 100 mm and a thickness of about 1 to 2 mm can be used.

  The reinforcing material 300 passes through the side surface portion 4 (region R2) from the bottom portion (region R3) of the back surface portion 3, and then passes through the front surface portion 2 (region R1), and then the side surface portion 4 shown in FIG. It is provided so as to pass through the opposing side surface portions and reach the bottom portion of the back surface portion.

  Next, the attachment position of the reinforcing member 300 to the core member 200 will be described in more detail with reference to FIG. Referring to FIG. 4, the reinforcing member 300 (310, 320) rises upward from the region R <b> 3 located on the back surface portion 3, and then passes through the region R <b> 2 located on the side surface portion 4. The region R2 is included in a central portion 230 in the height direction of the core member 200 (a portion located in the middle when the total height L of the core member 200 is divided into three equal parts). The reinforcing material 300 is bent on the side surface portion 4. Thereafter, the reinforcing material 300 passes through the region R1 located in the front surface portion 2. The region R1 is included in the upper half of the core member 200 (the portion located on the upper side when the total height L of the core member 200 is divided into two equal parts). Thereafter, the reinforcing member 300 reaches the bottom of the back surface portion 3 through a path symmetrical to FIG. 4 on the back surface side of the portion shown in FIG. In the present specification, as shown in FIG. 5, the “back surface portion 3” refers to a position from a position facing the handle 400 in the radial direction to a position rotated by 60 ° to the left and right around the center O of the core member 200. Means range.

  Next, the effect of reinforcement by the reinforcing material 300 will be described with reference to FIGS. 6 to 9 show a state in which the cover 600 is attached to the golf bag 1.

  With reference to FIG. 6, when golf bag 1 is lifted in the direction of arrow DR <b> 1 using handle 400, a relatively large force acts on core member 200 located around the attachment portion of handle 400. In the present embodiment, the upper end of the handle 400 is connected to the reinforced frame part 210, and deformation of this part does not become a problem. On the other hand, reinforcement for suppressing deformation of the core material 200 is necessary in the vicinity of the portion to which the lower end of the handle 400 is connected (region R1). In the present embodiment, since the core member 200 located in the region R1 is reinforced by the reinforcing members 310 and 320, deformation of this portion is suppressed.

  Referring to FIG. 7, when the golf bag 1 is lifted in the direction of the arrow DR <b> 1 ′ using the shoulder belt 500, a relatively large force acts on the core member 200 located around the attachment portion of the shoulder belt 500. In the present embodiment, the upper end of the shoulder belt 500 is connected to the reinforced mouth frame portion 210, and deformation of this portion does not become a problem. On the other hand, reinforcement for suppressing deformation of the core material 200 is necessary in the vicinity of the portion to which the lower end of the shoulder belt 500 is connected (region R1 ′). In the present embodiment, since the core member 200 located in the region R1 ′ is reinforced by the reinforcing member 320, deformation of this portion is suppressed.

  Note that, in a general golf bag 1 having a total core height of about 850 mm to 900 mm, the center of gravity is located approximately at ¾ of the total core height. For this reason, the handle 400 and the shoulder belt 500 are positioned so that their centers are slightly above the center of gravity so that the mouth frame 210 faces slightly upward when the golf bag 1 is lifted using them. Provided. Therefore, the handle 400 is attached to the upper part of the core member 200. For this reason, as described above, by providing the reinforcing member 300 so as to pass through the upper half of the core member 200 in the front surface portion 2, the core member 200 positioned at the attachment portion of the handle 400 in the general golf bag 1. It becomes possible to reinforce. Further, since the upper end of the shoulder belt 500 is fixed to the mouth frame portion 210 located at the upper end portion of the core member 200, the lower end of the shoulder belt 500 is near the center of the core member 200 in the height direction (the It is fixed to a portion located between about 3/8 to 5/8 of the total height). By providing the reinforcing member 300 on the above-described path, the core member 200 positioned at the attachment portion of the shoulder belt 500 can be reinforced in the general golf bag 1.

  When the golf bag 1 is stored in a car trunk or the like, the golf bag 1 is placed sideways. Referring to FIG. 8, when golf bag 1 is placed sideways, the center of main body 100 and core material 200 in the height direction (left-right direction in FIG. 8) due to the force from above (the force in the direction of arrow DR <b> 2). Since deformation is likely to occur in the portion (region R2), reinforcement for suppressing deformation of this portion is necessary. In the present embodiment, since the core member 200 located in the region R2 is reinforced by the reinforcing members 310 and 320, the deformation of this portion is suppressed.

  Referring to FIG. 9, when the golf bag 1 is lowered to the ground in the direction of the arrow DR3, the bottom portion (region R3) of the back surface portion 3 facing the handle 400 tends to be in contact with the ground first. Reinforcing is necessary to suppress this. In the present embodiment, since the core member 200 located in the region R3 is reinforced by the reinforcing members 310 and 320, deformation of this portion is suppressed.

  As described above, in the golf bag 1 according to the present embodiment, the deformation of the core member 200 can be suppressed by the reinforcing members 310 and 320 in each aspect when the bag is used. The sheet material to be made can be made thinner. As a result, the weight reduction of the golf bag 1 can be achieved.

  Next, an example of a method for manufacturing the golf bag 1 will be described with reference to FIGS. Referring to FIG. 10, first, reinforcing members 310 and 320 are bent and fixed on the main surface of sheet material 2000 in an arch shape. Another method for attaching the reinforcing members 310 and 320 is to sew a cloth in an arch shape on the sheet material 2000 and then pass the reinforcing members 310 and 320 through the cloth. In the present embodiment, the reinforcing members 310 and 320 are formed so as to extend in substantially the same direction and pass over the regions R1, R2, and R3 described above. Thus, by providing a plurality of reinforcing materials, it is possible to effectively reinforce a relatively wide range of sheet materials 2000 while suppressing an increase in the weight of the reinforcing material.

  Referring to FIG. 11, a cylindrical member constituting core material 200 is configured by winding sheet material 2000 provided with reinforcing material 300 in the direction of arrow DR200.

  Although the embodiment of the present invention has been described above, 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.
