Description

  The present invention relates to a sports shoe bag. In the following description, golf shoes are taken as an example, but the present invention can also be applied to other baseball shoes, soccer shoes, and the like.

  A golf shoe shoe includes a seat plate (mounting base) embedded in the sole and a pin (heel body) attached to the seat plate, both of which are detachable. A method for making them both detachable is, for example, by screwing a male screw provided at the base of the pin into a female screw inside the seat plate.

  Since about 10 to 30 golf shoes for both the left and right legs are provided, removing and attaching all the pins is a time-consuming and labor-intensive operation. In addition, those attached with screws may gradually loosen with the golfer's swing and eventually fall off.

In order to solve this problem, the present inventor, in the following Patent Document 1, "consisting of a heel body having a grounding portion and a mounting base for the heel body, and any element of the heel body and the mounting base, It comprises a trunk portion having a bulging portion that bulges only on one side in the lateral direction at the distal end portion, and a base portion that supports the bulging portion, and the other element of the heel body and the mounting base is a base portion and a ring that protrudes from the base portion And a ring for sports shoes characterized in that the ring is provided with a notch that can accommodate the bulging portion.
JP2001-137909

  In Patent Document 1, a “bulging portion that bulges only on one side in the lateral direction at the tip” is attached to the heel body, while “an incision that can accommodate the bulging portion” is provided on the mounting base. In order to combine these, the attachment / detachment has directionality. Although it strongly resists the force against this directionality, it tends to be weak against a force in the same direction as that directionality. The present invention is an improvement of the invention of Patent Document 1, which increases resistance against force in the same direction as the direction of attachment and detachment, thereby further preventing loosening and falling off of the heel. Objective.

  The present invention comprises a heel body having a grounding portion and a mounting base for the heel body, and the heel body has a trunk portion having a bulge portion that bulges only on one side in the lateral direction in the head, and supports the bulge portion. The mounting base comprises a base and a ring projecting from the base, and the ring is provided with a notch capable of accommodating the bulging portion. It comprises at least two parts, a first part including a base part and a second part including a base part, wherein the first and second parts are separable and connectable.

  Since the present invention does not use a screw to attach and detach the bag main body and the mounting base, the manufacturing cost can be reduced. In addition, it is easy to attach and detach because it is simply pushed in or lifted with a tool without using a screw. As a result, the time required for attaching and detaching 10 to 30 bag bodies could be greatly reduced. Also, unlike the case of using screws, there is little risk that the heel body will loosen or fall off.

  Furthermore, according to the present invention, since the heel body is composed of at least two parts, the first part including the trunk and the second part including the grounding part, the load applied to the grounding part is not transmitted to the trunk as it is. It is absorbed by the gap between the part and the second part. As a result, resistance against not only the force in the direction opposite to the direction of attachment / detachment but also the force in the same direction can be obtained, and the loosening of the bag main body can be prevented. As a result, the risk of falling off the main body of the bag was significantly reduced.

  It is preferable that the second portion has a through hole, and the two portions are coupled so that the trunk portion of the first portion is inserted through the through hole. In order to further strengthen the coupling, it is preferable to provide a retaining disc in the first portion.

  It is preferable to provide a gap between the first portion and the second portion. When separating the two parts, a tool such as a spatula is inserted into this gap.

  The grounding portion is preferably provided in both the first portion and the second portion in order to stabilize the heel.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a cross-sectional view of a golf shoe bag according to a first embodiment of the present invention embedded in a shoe sole.

  As is apparent from the figure, a mounting base 2 is embedded in the shoe sole 1, and the heel body 3 is fitted into the mounting base.

  As shown in FIG. 2 (sectional view), FIG. 3 a (plan view), and FIG. 3 b (bottom view), the heel body 3 includes a first portion 31 including at least a trunk portion 33 and a second portion 32 including a base portion 37. The first and second portions 31 and 32 can be separated and combined.

  As shown in FIG. 2, the trunk portion 33 of the first portion 31 has a substantially cylindrical shape, but its head portion 33a is a bulging portion 33b extending in the lateral direction. As a result, when viewed in plan, as shown in FIG. 3, the shape is half of an ellipse. As shown in FIG. 2, the bottom 33c of the bulging portion forms a flat surface. The non-bulged side of the trunk portion 33 forms a smooth chamfered portion 33d.

  As shown in FIG. 2, the first portion 31 further includes a disk portion 35 and a grounding portion 36. The disc part 35 contacts the second part 32 when the first part 31 is coupled to the second part 32 and acts as a retaining member. In the embodiment shown in the drawing, the grounding portion 36 is formed by a central projection at one location that faces downward.

  The second portion 32 includes a base portion 37, a grounding portion 34, and a central hole 38 for penetrating the first portion. The base 37 has a thick mortar shape and gradually rises toward the periphery. A circular recess 39 is provided at the center of the base portion 37. When the first portion 31 and the second portion 32 are joined, the disc portion 35 is seated in the recess 39.

  In the illustrated embodiment, the grounding portion 34 is composed of several protrusions directed downward. The grounding portion 34 may have a pin shape or a plate shape in addition to the illustrated shape.

  As is obvious from the above description, in order to connect the first portion 31 and the second portion 32, the first portion trunk 33 is simply inserted into the central hole 38 of the second portion.

  4 and 5 show the mounting base 2 embedded in the sole 4 of the golf shoe according to the first embodiment of the present invention. FIG. 4 is a sectional view and FIG. 5 is a bottom view.

  The mounting base 2 includes a circular base 21 and a ring 22 provided at the center of the circular base 21 and protruding downward. In this embodiment, the “ring” is not a circle but a “D” shape. The circular base portion 21 is provided with a plurality of through holes 23 (eight in the drawing) for strong integration with the resin of the shoe sole 4. As shown in FIG. 4, approximately half of the base side of the ring 22 is provided with a notch 24 having a size and shape for receiving the bulging portion 33b. The bottom 25 of the cut is a flat surface. Further, the open tip of the ring 22 has an inclined portion 26 with a corner cut off inward.

  The mounting base 2 and the heel body 3 (the first portion 31 and the second portion 32) are usually all made of synthetic resin.

  In order to couple the heel body 3 and the mounting base 2, first, the first portion 31 and the second portion 32 of the heel body 3 are joined in the manner described above. Then, it is only necessary to push the scissors main body 3 into the mounting base 2 using a mounting tool. When such an instrument is not at hand, it can be pushed in with a finger. At first, the bulging portion 33b hits the tip of the ring 22 and there is resistance. However, if the bulging portion 33b is pushed in as it is, both the resins are slightly deformed, and the bulging portion 33b fits into the cut 24 of the ring 22. In this state, the bottom surface 33c of the bulging portion 33b and the bottom surface 25 of the notch 24 come into contact with each other, and the positions of the heel body 3 and the mounting base 2 are stabilized (see FIG. 1).

  In order to release the coupling between the scissors main body 3 and the mounting base 2, a dedicated instrument 41 is used as shown in FIG. The instrument 41 has a “<” shape or “Z” shape, and the tip is inserted into the gap 40 between the first portion 31 and the second portion 32, and the force is applied in the left direction (when the shape is “<”) or Add upwards (for "Z" type). Then, rotation starts around the contact portion between the bottom surface 33c of the bulging portion 33b and the bottom surface 25 of the notch 24, the trunk chamfer 33d slides down along the ring 22, and the engagement between the two is eventually released. As is clear from this description, the position where the gap 40 is provided must be on the non-expanded side of the trunk body 3 trunk. Although it is written that “special equipment” is used, if it is suitable for the purpose of lifting the main body along the inclined portion, a “spa” or a metal plate close to it can be used.

  FIG. 6 is a plan view of a bag main body 3A according to the second embodiment of the present invention. The only difference from the heel body 3 of the first embodiment is the shape of the bulging portion 33b '. The bulging portion 33b 'is an ellipse when seen in a plan view.

  FIG. 7 is a bottom view of the mounting base 2A according to the second embodiment of the present invention. The only difference from the mounting base 2 of the first embodiment is the shape of the notch 24 '. The bulging portion 24 'is an ellipse when viewed in plan. In addition, parts having the same functions as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
