Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-slip sole used for various work or fishing footwear.

[0002]

2. Description of the Related Art In fishing at a work site such as forestry or a rocky place, footwear such as an underground type in which a large number of pins are buried on the bottom surface of a rubber bottom to prevent slipperiness has been put into practical use. Has also been made. (For example, actual Kaihei 4
See -79501. )

[0003] The sole used for such footwear is provided with a large number of pins serving as spikes and support seats for supporting the weight on the bottom surface, and when a load is applied to the sole and the sole is subjected to a load, the pins are turned off. It digs into the tread and exerts anti-slip properties, and also supports the body.

[0004] However, the conventional anti-skid sole has a flat bottom surface and does not take into account the shape of the sole, especially the shape of the stepping portion, so that it does not fit well to the foot when worn, so There was an inferior grudge. In addition, the bottom tends to be harder than other footwear due to the embedding of the pin, and there is a problem that the comfort is further reduced.

[0005]

However, even with such a non-slip bottom, the fact that it fits the foot and has a sufficient feeling of grounding is necessary from the viewpoint of ensuring work safety and reducing fatigue. The present invention seeks to provide an anti-skid sole for footwear that solves these problems.

[0006]

That is, the present invention has been made to solve the above-mentioned problem, and the gist of the invention is that a large number of pins and support seats are provided on the bottom surface of the bottom. A non-slip bottom, wherein a foot portion of the bottom is formed in an upwardly curved shape, and a pin provided in the foot portion is vertically held and buried, and is similarly provided in the foot portion. The support seat to be formed is formed so that its central axis is vertical.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings showing examples. 1 to 3
1 shows an example of a non-slip sole to be used for footwear of the underground type, of which FIG. 1 is a bottom view, FIG. 2 is an II-II end view of FIG. 1, and FIG. 3 is an III-III end view of FIG. Yes, FIG. 4
FIG. 6 to FIG. 6 are enlarged sectional views of each part.

In FIG. 1, reference numeral 1 denotes a bottom main body, which is formed of rubber or synthetic resin, and has a bottom surface 1A provided with pins and support seats to be described later. Reference numeral 1B denotes a rear surface finished to a substantially smooth surface, through which an upper (not shown) is joined in accordance with a conventional method. In the figure, 1C is a step portion surrounded by a virtual line, 1D is a tread portion, and 1E is a toe crotch portion. In this example, a thin anti-slip portion 1E is formed at the finger crotch portion of the bottom body 1 as a non-slip bottom for use in footwear of an underground type. It is also possible to form a shoe, or conversely, to form no crotch.

In the present invention, a large number of pins 2 and support seats 2 are provided on the bottom surface 1A of the bottom main body 1 in a dotted manner. As shown in FIG. 4, the pin 2 has a inverted gate shape, and a pin main body 2A having a horizontal portion bent in a letter shape is embedded via a holding portion 2B. Such a pin body 2A
The use of is advantageous in that the pin can be prevented from coming off, which is convenient. However, a single pin body may be used alone or two or more pins may be twisted and embedded. The pin body 2A is made of a metal material such as stainless steel formed into a predetermined shape, and in some cases, a pin having a surface subjected to a coating treatment to enhance adhesion to a bottom material may be used.

In FIG. 5, reference numeral 3 denotes a support seat having a trapezoidal cross section as shown in FIG. 5, which is formed integrally when the bottom body 1 is formed. The support seat 3 has a function of supporting weight when wearing footwear having a non-slip sole, and the pin is inclined by a load when stepped on, as in the case where the sole is constituted only by the pin. It plays a role in preventing it from bending or bending. Therefore, the length 1 of the support seat 3 is preferably set to be equal to or slightly shorter than the length L (see FIG. 4) including the pin 2 so that the tip of the pin acts when worn. In the example shown in the figure, the shape of the bottom surface of the support seat 3 is triangular.
Any shape such as a rectangle can be used. Further, a fine uneven surface for preventing slippage can be formed on the ground contact surface 3A of the support seat 3. Further, as long as the support seat 3 is formed so that its central axis is vertical, the tip may be not only flat but also round or sharp.

In the present invention, in order to enhance the feeling of fit of the foot when worn and to improve the feeling of contact with the ground, the sole 1C
Is formed in an upwardly curved shape. However, if the above-mentioned pin 2 and support seat 3 are inadvertently provided on the portion 1C without stepping on the pin, the curvature of this portion causes the pin and the support seat to be inclined and Since the object is not achieved, as shown in FIG. 6, the pin 2 provided in this portion is buried so as to be held vertically like other portions, and the support seat 3 has its central axis set to be vertical. Is formed. In addition, the lower end surfaces of the pin body 2A and the support seat 3 provided in the stepping portion 1C are:
Due to the upward bending of this portion, it is slightly inside the ground level surface as shown in FIG.

As described above, when the pins 2 and the support seats 3 provided on the stepping portion 1C are formed, the stepping portion 1C can be used when worn.
The pin 2 and the support seat 3 play the same role of slip prevention and weight support as other parts even when the foot part 1C steps on objects, etc. And the pin 2 provided in the step 1C
And since the support seat 3 is formed vertically regardless of the inclination of the step 1C, the foot can be supported while holding the ground surface in the same manner as the other parts at the time of grounding, and an excellent anti-slip sole can be provided. Can be provided.

In the illustrated example, the length of the pin 2 and the support seat 3 provided on the stepping portion 1C is substantially equal to the length of the pin 2 and the support seat 3 provided on the other portion. Are located inwardly by the amount of curvature above the ground level determined by the other parts. If necessary according to the flexibility of the material used for the bottom or the purpose of work, it is possible to provide this tip position by appropriately changing it to a range of the length of substantially the same position as the position of the ground level. This makes it possible to adjust the feeling of contact with the ground for wearing purposes. Step 1 like this
When the lengths of the pins 2 and the support seats 3 provided at C are increased to the ground level, the thicknesses and shapes of the pins 2 and the support seats 3 are made thicker than those of the others, and the length of the holding portion 2B is lengthened. Is preferable in terms of strength.

Reference numeral 4 in the figure is a groove formed so as to extend in the width direction of the tread portion 1D at the bottom. When the groove 4 is provided in this manner, the tread portion 1D is easily bent in the front-rear direction, which is convenient. It is. It is preferable that two or several grooves 4 are provided as shown in the figure, but the grooves 4 are not necessarily grooves but may be streaks extending lower than other protrusions and serving to assist bending.

[0015]

As described above, the present invention has a structure as described in detail above, so that the pin and the support seat provide a predetermined anti-slip characteristic when worn, and an upper curved portion provided on the stepping portion and the upper curved portion. The presence of the pin and the support seat provided in consideration of the shape of the portion has an advantage that the foot can be fitted to the foot to provide an excellent feeling of contact with the ground, and also provide a slip-resistant sole for footwear that is comfortable and less fatigued.
