Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to working boots which are mainly worn when performing work such as maintenance of a lawn in a golf course or the like.

[Conventional technology]

Conventionally, athletic shoes and rubber or synthetic resin boots have been worn when performing work such as lawn mowing on a golf course, watering the lawn, and reattaching the lawn. However,
Since the back part of the athletic shoe is made of a cloth or the like through which moisture easily penetrates, there is a drawback in that moisture gets into the inside of the shoe during work, which makes the operator uncomfortable. For this reason, rubber or synthetic resin boots are often worn in the limbs so that water does not easily penetrate.However, conventional boots are intended to be worn in rainy or wet places. In order to prevent slippage in the direction, the ground contact surface of the shoe sole has a mountain-shaped deep unevenness, so that the weight of the wearer acts only on the tip of this mountain-shaped deep unevenness. Therefore, it is easy to leave a footstep of the shoe on the lawn, and the lawn is often damaged.

[Problems to be solved by the device]

In this way, when performing work such as lawn mowing on the golf course, watering the lawn, and reattaching the lawn in this way, water penetrates inside the shoe like a conventional sports shoe and the foot gets wet. An object of the present invention is to provide a work shoe which eliminates a defect that gives an unpleasant feeling to an operator, is hard to slip even on a wet lawn, and does not leave a footstep of the shoe on the lawn or damage the lawn.

[Means for Solving the Problems]

As a result of various investigations by the present inventor to solve such problems,
The torso is made of rubber or synthetic resin, which is a non-water-permeable material like conventional boots, and the structure of the ground contact side of the sole is slippery, does not damage the lawn, and leaves no footprint. By clarifying what should be done, the present invention was completed with a special structure on the ground contact side of the shoe sole.

Hereinafter, an embodiment of a work shoe according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view of the work boots according to the present invention, FIG. 2 is a bottom view of the sole of the work boots according to the present invention shown in FIG. 1, and FIG. 3 is A-A in FIG. It is a line end view.

In the drawings, 1 is a trunk body made of rubber or synthetic resin such as polyvinyl chloride, and 2 is a shoe sole provided on the bottom of the trunk body 1. This shoe sole 2 has at least a front sole 3 and a heel 4
Around the outer periphery of the rim, there are provided peripheral protrusions 3a and 4a whose ground planes are on the same plane, and the front bottom part 3 and the heel part 4 are slightly protruded from the peripheral protrusions 3a and 4a by the same height. Planar projections 5 parallel to each other are provided on both sides of a first concave portion 6 that is flush with the peripheral edge projections 3a and 4a, and the flat convex portions 5 and the first concave portions 6 are provided on the periphery of the first convex portion 5. A plane-shaped second concave portion 7 which is deeper than the concave portion 6 is provided. Further, 8 is a tread portion located between the front bottom portion 3 and the heel portion 4, and this tread portion 8 is configured similarly to the front bottom portion 3 and the heel portion 4, and clearly shows the front bottom portion 3 and the heel portion. It is preferable that the structure is indistinguishable from the front bottom part 3 and the heel part 4, but the depth from the ground contact surface of the front bottom part 3 and the heel part 4 is not too deep. It is preferable to set. Then, in such a configuration, in the portions excluding the peripheral protrusions 3a and 4a of the front bottom portion 3 and the heel portion 4, the proportions of the planar convex portion 5, the first concave portion 6, and the second concave portion 7 are respectively It is necessary to be in the range of 30-40%, 15-25%, 35-55%. This is because if the proportion of the flat convex portion 5 in each of the front bottom portion 3 and the heel portion 4 is less than 30%, the area of the ground contact portion is too small and the lawn damage prevention effect deteriorates, and if it exceeds 40%. If the proportion of the first concave portion 6 is less than 15%, the area of the ground contact portion combined with the planar convex portion 5 is too small and the lawn damage preventing effect deteriorates. %, The area of the ground contact portion combined with the flat convex portion 5 becomes too large to reduce the anti-slip effect, and when the flat convex portion 5 is worn, the anti-slip effect remarkably decreases. Two recesses 7
If the ratio of the flat convex portion 5 is less than 35%, the area of the ground contact portion including the planar convex portion 5 and the first concave portion 6 becomes too large, and the anti-slip effect decreases, and if it exceeds 55%, the planar convex portion 5 This is because the area of the ground contact portion including the above and the first concave portion 6 becomes too small, and the effect of preventing damage to the lawn deteriorates. As shown in FIG. 2, the planar convex portions 5 are at least one set of parallel planar convex portions among the parallel planar convex portions 5 and the adjacent parallel planar convex portions 5 that sandwich the second concave portion 7. It is preferable that 5 and 5 are formed so as to intersect each other in that direction.

[Action]

The boots for work according to the present invention having such a structure are the body 1
Since it is made of rubber or synthetic resin, even if it is worn on a wet lawn, moisture does not penetrate from the outside of the shoe into the inside of the shoe. In addition, at least the front sole portion 3 and the heel portion 4 of the shoe sole 2 along the outer circumference thereof, the peripheral protrusions 3 having the grounding surface side in the same plane.
Since the a and 4a are provided, the presence of the peripheral protrusions 3a and 4a exerts an anti-slip effect in all directions regardless of the walking direction of the wearer. At this time, as shown in FIG. 2, at least one set of the parallel flat convex portions 5 among the parallel flat convex portions 5 and the parallel flat convex portions 5 which are adjacent to each other with the parallel flat convex portion 5 and the second concave portion 7 sandwiching the direction. When they are formed so as to intersect with each other, not only the peripheral protrusions 3a and 4a but also the planar convex portion 5 can more effectively exert the anti-slip effect in all directions. Further, the peripheral projections 3a, 4a are provided on the front sole portion 3 and the heel portion 4 which constitute the ground contact surface of the shoe sole 2.
Further, a flat convex portion 5 is provided on both sides of the first concave portion 6 which protrudes a little more by the same height and forms the same plane as the peripheral protrusions 3a and 4a. A planar second concave portion 7 that is deeper than the first concave portion 6 is provided on the peripheral edge of the one concave portion 6, and the proportion of the planar convex portion 5, the first concave portion 6, and the second concave portion 7 is the above. Since it is within the predetermined range, the portion to be grounded on the lawn is two portions, that is, the planar convex portion 5 and the first concave portion 6 which are respectively planar, so that the lawn is not damaged and is simply Since it is not flat, it is not slippery, and the presence of the second concave portion 7 can effectively exert the anti-slip effect of the first concave portion 6, and even if the planar convex portion 5 is worn, the anti-slip action still remains. That is the effect.

[Effect of device]

As described in detail above, the work boots according to the present invention have the trunk body made of a non-water-immersive material made of rubber or synthetic resin like conventional boots, so that the boots are worn on the lawn that is wet when sprinkled or with morning dew. Moisture does not permeate into the inside of the shoe even if it is used, and at least the front sole and the heel are provided with peripheral protrusions along the outer periphery of which the ground contact side is flush with the front and the front. The bottom portion and the heel portion each have a planar convex portion slightly protruding from the peripheral protrusion by the same height, a first concave portion that forms the same plane as the peripheral protrusion, and a planar second concave portion that is deeper than the first concave portion. 30% to 40%, 15% to 25%, and 35% to 55%
Due to the configuration provided within the range, it is not only slippery even on a wet lawn, but also does not damage the lawn, so it is not necessary for workers who perform maintenance and management on the lawn like a golf course. It greatly contributes to the safety and protection of the lawn, and its practical value is enormous.
