DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe sole for a fishing shoe used as a shoe sole of a shoe worn for fishing, and more particularly, to a tread layer and a cushion layer having a lower elasticity than the tread layer. And a shoe sole for fishing shoes comprising:

[0002]

2. Description of the Related Art Conventionally, as soles for this kind of fishing shoes,
The one shown in FIG. 5 is known. That is, in the shoe sole shown in the figure, a low-elastic cushion layer 52 (midsole) having excellent elasticity is provided on the upper surface of a ground surface layer 51 (outer sole) made of relatively hard and high-elastic rubber with an adhesive. It is bonded and laminated, and is used by being bonded to the bottom side of the upper portion 53 that covers the foot.

[0003] If the shoe with the sole attached is worn for fishing, for example, even when walking on a rough rocky place, the local deformation of the ground contact surface layer 51, that is, the deformation according to the shape of the ground is caused by the deformation. In addition to preventing the wearer from being pushed up to the sole of the foot, even when walking on a hard place such as a breakwater or a rock, the cushioning layer 52 absorbs the impact during walking.

[0004]

However, in the shoe sole for fishing shoes having the above-mentioned conventional ground contact layer and cushion layer, if the weight of the wearer is applied to the cushion layer during walking,
Since the constituent members of the cushion layer in the part where the weight is applied move to the outer peripheral side so as to avoid the weight and the cushion layer spreads to the outer peripheral side, the shock absorption is reduced, and the cushion layer is easily shaken left and right, Sometimes it was difficult to walk.

In view of the above, the present invention has been made in view of the above-mentioned conventional problems, and provides a shoe sole for a fishing shoe which is easy to walk while having a ground contact surface layer and a cushion layer, which hardly reduces shock absorption. The task is to provide

[0006]

Means for Solving the Problems In order to solve the above problems,
A shoe sole for a fishing shoe according to the present invention includes a grounding layer and a cushion layer laminated on the upper surface of the grounding layer and having a lower elasticity than the grounding layer. A shoe sole for a fishing shoe to be attached, on a top surface of the ground contact layer, a peripheral wall protruding upward at a peripheral edge and surrounding the outer periphery of the cushion layer, and a plurality of reinforcing ribs bridged in the peripheral wall. And the inside of the peripheral wall is partitioned by the reinforcing ribs to form a plurality of recesses, and the lower surface of the cushion layer includes a plurality of protrusions that can be fitted into the plurality of recesses, respectively. And the convex portions are fitted into the concave portions, respectively.

[0007] In the shoe sole for fishing shoes having the above structure, even if the weight of the wearer is applied to the cushion layer during walking, the outer periphery of the cushion layer is surrounded by the peripheral wall, and the peripheral wall is expanded toward the outer peripheral side by the reinforcing ribs. Is suppressed, and the possibility that the cushion layer spreads to the outer peripheral side is reduced. Moreover, the plurality of convex portions of the cushion layer are fitted into the plurality of concave portions formed by partitioning the inside of the peripheral wall with the reinforcing ribs, and the convex portions are supported by the concave portions, and are located near the convex portions. The movement of the member constituting the cushion layer is restricted so as to be restricted by the convex portion, and the member constituting the cushion layer between the convex portions supported by the concave portion is regulated by both convex portions. The movement of the cushion layer is restricted, so that the cushion layer is less likely to move right and left.

[0008] In the sole for fishing shoes according to the present invention,
It is preferable that the height of the protrusion is set longer than the depth of the recess. By adopting such a configuration, the convex portion fitted into the concave portion can expand and contract in the vertical direction in the concave portion, so that it is excellent in shock absorption and can suppress the protrusion to the cushion layer by the reinforcing ribs, and The feeling of thrust can be reduced.

It is preferable that the cushion layer is made of a foam. Since the foam has not only shock absorption but also air with extremely low thermal conductivity, by adopting the above configuration, the temperature of the ground is hardly transmitted to the soles of the foot, and even in winter or summer Fishing can be done comfortably.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a top view showing a shoe sole for fishing shoes of the present embodiment. As shown in FIG. 1, the sole for a fishing shoe of the present embodiment includes a cushion layer 2 called a so-called midsole on an upper surface (anti-ground contact surface) of a so-called outer sole. Are laminated.

FIG. 2 is a sectional view taken along line AA of FIG. As shown in FIG. 2, an upper surface of the ground plane layer 1 and a lower surface of the cushion layer 2 are formed in a shape to be fitted to each other,
These are in a state where they are fitted to each other.

FIG. 3 is a top view showing the ground plane layer 1. The ground plane layer 1 is a member having higher abrasion resistance and higher elasticity than the member forming the cushion layer 2, for example,
Normally, a high styrene rubber having a higher styrene content than a styrene / butadiene rubber having a styrene content of 23.5% is formed into a footprint (foot flat shape).

The upper surface of the ground plane layer 1 is provided with a peripheral wall 1a projecting upward at a peripheral edge and surrounding the entire side surface of the cushion layer 2 in a ring shape so that the cushion layer 2 can be fitted into the peripheral wall 1a. It is configured. In addition, the peripheral wall 1a
Of the cushion layer 2 is set to be substantially the same as the thickness of the cushion layer 2.
Has a configuration in which the upper surface can be fitted until it is flush with the upper end of the peripheral wall 1a.

Moreover, in the peripheral wall 1a surrounded by the peripheral wall 1a, a plurality of reinforcing ribs 1b and 1c projecting upward extending between arbitrary two points of the peripheral wall 1a are provided in a lattice shape. Specifically, a plurality of vertical ribs 1b extending in the front-rear direction connecting the toe side and the heel side of the peripheral wall 1a and a plurality of horizontal ribs 1c extending in the width direction connecting both sides of the peripheral wall 1a form a lattice pattern. It is provided integrally. The height of the reinforcing ribs 1b and 1c protruding from the peripheral wall is set lower.

The inside of the peripheral wall 1a is partitioned by the plurality of reinforcing ribs 1b and 1c provided in a lattice shape, and the plurality of recesses 1d and the reinforcing ribs 1b and 1c surrounded by the reinforcing ribs 1b and 1c and the peripheral wall 1a. Are formed in the upper surface of the ground plane layer 1 respectively.

The cushion layer 2 is made of a member having a lower elasticity than the ground contact layer 1 and excellent in shock absorption, for example, foamed polystyrene, polyurethane, or the like, is formed into a foot shape. The cushion layer 2 is provided with convex portions 2a, which can be fitted into the concave portions 1d, in a lattice shape at positions corresponding to the concave portions 1d on the lower surface.

As shown in FIG. 4, each of the cushion layers 2 has a corresponding concave portion 1d corresponding to each convex portion 2a.
As a whole, the upper surface of the cushion layer 2 and the upper end of the peripheral wall 1a are fitted into the peripheral wall 1a of the ground plane layer 1 such that they are substantially flush with each other. In order to prevent the cushion layer 2 from inadvertently separating from the ground plane layer 1, for example, an adhesive (not shown) is interposed between the cushion layer 2 and the ground plane layer 1. Is the peripheral wall 1 of the ground plane layer 1
It is adhered in a state where it is fitted in a.

The shoe sole for fishing shoes of the present embodiment is constructed as described above. For example, the upper surface of the cushion layer 2 is adhered to the bottom side of the upper part (not shown).
It is used by being attached to the bottom side of the upper part.

The sole for fishing shoes of the present embodiment is constructed as described above and has the following advantages.
That is, in the above embodiment, the cushion layer 2 is fitted into the peripheral wall 1a of the ground plane layer 1 so that the upper surface of the cushion layer 2 and the upper surface of the peripheral wall 1a are substantially flush.
Both the upper end of the peripheral wall 1a and the cushion layer 2 can be simultaneously adhered to the bottom surface of the planar upper portion. Further, when the cushion layer 2 is adhered to the bottom surface of the upper portion or the like, the cushion layer 2 is not exposed to the outside, and the possibility of damaging the cushion layer 2 is reduced. Therefore, even if a foam material having low abrasion resistance or the like (a foam material has a lower abrasion resistance than an unfoamed material) is used as a member constituting the cushion layer 2, the foam material contacts the outside. Is prevented from being worn.

Although the sole for fishing shoes of the present embodiment is constituted as described above, the sole for fishing shoes of the present invention is not limited to the above constitution, and the design can be changed as appropriate. For example, in the above embodiment, the inside of the peripheral wall 1a is partitioned by the reinforcing ribs 1b and 1c, and the concave portion 1d surrounded by the reinforcing ribs 1b and 1c and the concave portion 1d surrounded by the reinforcing ribs 1b and 1c and the peripheral wall 1a are formed. However, in the present invention, only the concave portion 1d surrounded by the reinforcing ribs 1b and 1c and the peripheral wall 1a may be formed.

In the above embodiment, the peripheral wall 1a
Is configured to protrude upward to encircle the entire side surface of the cushion layer 2 in a ring shape, but may be configured to encircle the lower region of the side surface in a ring shape within the intended range of the present invention. is there.

[0022]

As described above, in the shoe sole for fishing shoes according to the present invention, the possibility that the cushion layer spreads to the outer peripheral side is reduced,
In addition, since the cushion layer is less liable to be shaken, there is little possibility that the original shock absorption of the cushion layer is reduced, so that the cushion layer has an advantage that it is easy to walk.
