Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to fishing work shoes that are mainly worn when fishing large fish such as salmon and trout using fishing nets. be.

[Conventional technology]

Traditionally, fishing work boots made of rubber or synthetic resin have been worn when fishing in the distant sea, where large fish such as salmon and trout are caught using fishing nets. . However, the soles of conventional fishing work shoes have a structure in which the front sole and heel are clearly distinguished, and the height of the heel is considerably higher than the height of the front sole. In addition, the front bottom and heel have a concavo-convex pattern that extends in a line approximately perpendicular to the line connecting the tip of the toe and the rear end of the heel to provide an anti-slip effect. It was something that was happening.

As a result, when fishing for large fish such as salmon and trout is carried out using fishing nets such as purse seines, drift nets, and set nets, the fishing nets used have fairly wide openings, making fishing difficult. The entire heel of work shoes can get stuck in the mesh of the fishing net, resulting in unexpected accidents such as the worker being dragged by the fishing net and falling into the sea. Since the material that makes up the tread of the shoe is the same as the material that makes up the main body of the sole, it has the disadvantage of being slippery.

[The problem that the idea attempts to solve]

The present invention is designed to solve the problem that when fishing in the distant sea, where large fish such as salmon and trout are caught using fishing nets, the entire heel of the fishing work shoes gets stuck in the mesh of the fishing net. To provide working shoes for fishing that can eliminate the drawback of the occurrence of the phenomenon, are hard to slip even in a wet and slippery place such as the deck of a fishing boat, and can withstand long-term use.

[Means to solve the problem]

As a result of various studies to solve this problem, the inventor of the present invention decided to make the torso made of rubber or synthetic resin, which is an impermeable material like conventional fishing work shoes, and to make the torso part of the shoe made of rubber or synthetic resin, which is a non-water permeable material, and to make the sole of the shoe on the ground side. Ceramic powder with excellent anti-slip performance is embedded to make it difficult to slip, and a peripheral protrusion is provided along the outer periphery, and the peripheral protrusion slopes gently from the front bottom at the part where you do not step on it, and has the maximum slope with respect to the horizontal plane on the heel side. It was discovered that the structure of the contact surface side, which is connected in an arc shape with an angle of less than 45 degrees and is surrounded by the peripheral protrusions, has a specific unevenness. The present invention was completed with a special configuration for the ground plane side.

Hereinafter, one embodiment of fishing work shoes according to the present invention will be described in detail with reference to the drawings.

Figure 1 is a front view of fishing work shoes according to the present invention;
2 is a bottom view of the sole of the fishing work shoe according to the present invention shown in FIG. 1, and FIG. 3 is an end view taken along line A--A in FIG. 2.

In the drawing, 1 is a torso body made of rubber or synthetic resin such as polyvinyl chloride, and 2 is a sole provided at the bottom of the torso body 1. This sole 2 is provided with peripheral protrusions 3a and 4a whose contact surfaces are on the same plane along the outer periphery of the front sole 3 and heel 4, and the peripheral protrusions 3a and 4a in the non-stepping part 8 and the front sole 3. The front bottom part 3, the heel part 4, and the non-stepping part 8 are connected in an arc shape with a gentle inclination from the bottom and the maximum inclination angle with respect to the horizontal plane on the heel part 4 side is less than 45 degrees. the peripheral protrusion 3a by the height;
4a, a first recess 6 that is flush with the peripheral protrusions 3a and 4a, and a second planar recess 7 that is deeper than the first recess 6. The planar convex portion 5 and the first concave portion 6 are provided with the peripheral protrusions 3a, 4a from the ground surface side.
Ceramic powder is buried up to the body 1 side from the height of .

In such a configuration, in the portions of the front bottom portion 3 and the heel portion 4 excluding the respective peripheral protrusions 3a and 4a, the proportions occupied by the planar convex portion 5, the first concave portion 6, and the second concave portion 7 are respectively 30~40%, 15~
25%, preferably in the range of 35 to 55% in order to effectively exhibit the effects of the present invention. This is because if the proportion of the planar convex part 5 in each of the front sole part 3 and the heel part 4 is less than 30%, the area of the ground contact part is too small, resulting in poor stability and poor anti-slip effect; This is because if it exceeds the area of the ground contact part becomes too large and the anti-slip effect decreases, and if the proportion occupied by the first recessed part 6 is less than 15%, the area of the ground contact part combined with the planar convex part 5 is small. If it exceeds 25%, the anti-slip effect will be poor in uneven places, and if it exceeds 25%, the area of the ground contact area combined with the planar protrusion 5 will become too large when the planar protrusion 5 wears out, reducing the anti-slip effect. This is because the
If the proportion occupied by the second recess 7 is less than 35%, the combined area of the ground contact area of the planar projection 5 and the first recess 6 will become too large, reducing the anti-slip effect.
%, the combined area of the ground contact area of the planar convex portion 5 and first recess 6 becomes too small, and the anti-slip effect also decreases.

[Effect]

As described above, in the fishing work shoes according to the present invention, since the torso body 1 is made of rubber or synthetic resin, moisture does not penetrate from the outside of the shoes into the inside of the shoes. In addition, a peripheral protrusion 3a whose contact surface side is on the same plane along the outer periphery of the front sole 3 and heel 4 of the sole 2
and 4a, this peripheral protrusion 3
The presence of elements a and 4a provides an anti-slip effect in all directions, regardless of the walking direction of the wearer. The front sole part 3, heel part 4, and non-stepping part 8, which constitute the ground contact surface of the sole 2, have a planar convex part 5 that slightly protrudes from the peripheral protrusions 3a and 4a by the same height, and a peripheral protrusion 3a. , 4a, and a flat second recess 7 that is deeper than the first recess 6, the ground surface is not simply flat, making it difficult to slip. Not only can the anti-slip effect of the first recess 6 due to the presence of the second recess 7 be effectively exerted, but even if the planar protrusion 5 wears out, the anti-slip effect will still remain due to the presence of the first recess 6. This has the effect of doing so. Then, at the non-stepping part 8, the peripheral protrusion 3a
and 4a are connected in a circular arc shape that slopes gently from the front sole 3 and has a maximum angle of inclination of less than 45 degrees with respect to the horizontal plane on the heel 4 side.
It is rare for fish to penetrate deep into the mesh of a fishing net, and even if it does, it easily escapes from the mesh.

The peripheral protrusion 3 is also provided on this non-stepping portion 8.
A planar convex portion 5 that slightly protrudes from the same height as a and 4a, a first recess 6 that is flush with the peripheral protrusions 3a and 4a, and a planar second recess 7 that is recessed deeper than the first recess 6. In addition, ceramic powder is embedded in these planar convex portions 5 and first concave portions 6 from the ground plane side to the body body 1 side from the height of the peripheral edge protrusions 3a, 4a, so that there is no contact. The anti-slip effect is very good even when the ground becomes worn.

[Effect of idea]

As detailed above, the fishing work shoes according to the present invention have a torso made of a non-water-resistant material made of rubber or synthetic resin, similar to conventional fishing shoes, so that moisture does not penetrate into the inside of the shoes. The structure of the sole is such that a peripheral protrusion is provided along the outer periphery of the front sole and the heel, and the contact surface side is on the same plane, and the peripheral protrusion slopes gently from the front sole at the part where the foot is not stepped on. The heel part is connected in an arc shape with a maximum inclination angle of less than 45 degrees with respect to the horizontal plane on the heel side, which makes it difficult for the heel part to get into the mesh of the fishing net, but even if it does, it can be easily done. Furthermore, on the front bottom, heel, and non-stepping part, there is a planar convex part that slightly protrudes from the circumferential protrusion by the same height, a first concave part that is flush with the circumferential protrusion, and is deeper than the first concave part. A concave planar second concave portion is provided, and ceramic powder is buried in the planar convex portion and the first concave portion from the ground plane side deeper than the height of the peripheral protrusion. It is difficult to slip even on uneven or wet surfaces, and even if the contact surface is worn out, the anti-slip effect will not be lost for a considerable period of time. It greatly contributes to the safety of workers engaged in fishing operations in the distant sea, and its practical value is extremely large.
