[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to shoe soles such as sports shoes to be worn for sports and mountain climbing, boots for fishing, and athletic shoes optimally used for footwear for construction. It is intended to reliably prevent the fall due to sliding.

[0002]

[Prior art]

 Conventionally, typical shapes of non-slip formed on the lower surface of the sole of sports shoes to be worn for sports, mountain climbing, etc. are, for example, straight lines, corrugations, lightning bolts, diamonds, columns, etc. There is. Then, for example, sliding is prevented by providing a large number in a direction substantially orthogonal to the axis of the shoe sole body.

[0003]

[Problems to be solved by the device]

 However, for example, the above-mentioned conventional non-slip formed in a linear shape or a corrugated shape is provided in a direction substantially orthogonal to the axis of the sole body, and the shape thereof is relatively monotonous, and the direction of the bite into the ground at the time of touchdown is the shoe. Since it is limited to one direction orthogonal to the axis of the bottom, it exerts sufficient frictional force against the ground to prevent sliding forward and backward when performing a relatively light exercise such as normal walking. However, it was unsuitable for sufficiently preventing the forward and backward sliding or the fall due to the sliding when performing intense exercise such as sports and mountain climbing.

Further, in the conventional non-slip formed into a lightning bolt shape, a rhombus shape, a cylindrical shape, etc., the whole shape as one non-slip is formed by combining the fine line or curved line side portions. Therefore, the bite area of each bare side portion with respect to the ground becomes small. Therefore, the anti-skid function is not fully utilized. Therefore, it was not sufficient to prevent the sliding against the heavy exercise such as sports.

In addition, when the user's movement such as sports is intense during exercise and the force is applied from all directions such as the front-back direction and the left-right direction, slippage is prevented in order to prevent slipping or fall. It is necessary to consider the shape of.

Therefore, the present invention not only performs relatively light exercise such as walking, but also slides in the anteroposterior direction and falls due to sliding when performing intense exercise that exerts a momentary force such as when performing sports. The purpose is to surely prevent.

[0007]

[Means for Solving the Problems]

 In view of the above problems, the present invention has a generally arcuate lordotic anti-skid ridge that bulges toward the toe and a bulge that extends toward the heel on the lower surface of the sole body made of an elastic material such as rubber. We adopted a means to provide the arcuate kyphosis convex ridges so as to cross each other in a direction substantially orthogonal to the axis of the sole body.

[0008]

[Action]

 A generally arcuate lordotic anti-skid ridge that bulges toward the toe part, which is made of an elastic material such as rubber, and that extends in a direction substantially orthogonal to the axis of the shoe sole body, slides backward when it bites into the ground. To prevent falling, or to prevent slipping forward and falling. In addition, the generally curved arcuate anti-skid ridges that bulge toward the heel part bite into the ground to prevent forward sliding, and sliding prevents them from falling backwards on their backs.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 denotes a shoe sole that covers the bottom of sports shoes, mountain climbing shoes, boots for fishing, underground socks for construction, etc. The sole 1 has a substantially symmetrical shoe shape as shown in FIG. It consists of a pair of shoe sole bodies 2 and 2 '. The shoe sole bodies 2 and 2'are made of an elastic material such as rubber or synthetic resin.

Reference numeral 3 is a toe portion located at the tip of the shoe sole body 2, 2 ′, and 4 is a heel portion located at the rear end of the shoe sole body 2, 2 ′.

Reference numeral 5 is a slip formed on the lower surface of the shoe sole main body 2, 2 ′, and this slip 5 includes a front kyphosis anti-slip convex strip 5 A and a rear kyphosis anti-slip convex strip 5 B. It is formed by being projected in combination with the axis line X of 2 '.

The lordotic ridge 5A has a substantially arcuate shape that bulges toward the toe portions 3 of the pair of left and right shoe sole bodies 2 and 2 ', and extends along the axis X of the shoe sole bodies 2 and 2'. A large number are provided in a substantially orthogonal direction. Further, when the front kyphosis convex ridge 5A touches the ground E, it prevents the user from sliding backward and leftward and rightward by digging into the ground E in a substantially arcuate shape which bulges in the direction of the toe portion 3. At the same time, it prevents slipping and slipping forward.

Further, the kyphosis convex ridge 5B is formed in a substantially arc shape that bulges toward the heel portion 4 of the shoe sole body 2, 2 ', and is substantially orthogonal to the axis X of the shoe sole body 2, 2'. A large number are set in the direction. Then, after this, the non-slip convex ridges 5B bite into the ground E in a generally arcuate shape that bulges in the direction of the heel 4 when it touches the ground E to prevent sliding in the forward and leftward or rightward directions and To prevent falling.

Further, the relationship between the lordotic anti-skid ridges 5A and the kyphosis anti-skid ridges 5B is as shown in FIG. 1, FIG. 3, and FIG. By arranging the kyphosis anti-skid projections 5B between the arbitrary kyphosis anti-slip ridges 5A and the trailing kyphosis anti-slip ridges 5A, the kyphosis anti-slip ridges 5B and The tongue and groove 5A are crossed with each other at two points a and a'on the left and right of the axis X of the shoe sole bodies 2 and 2 '. The inside of the lordotic anti-skid ridge 5A or the kyphosis anti-skid ridge 5B is located in the approximate center surrounded by the approximately arc-shaped lordotic anti-skid ridge 5A and the approximately arc-shaped kyphosis anti-skid ridge 5B. A leaf-shaped enclosing small chamber part a located in a substantially tree, and several small chamber parts b on the left and right sides of the surrounding small chamber part a.₁, B₂, B ₃ ... and are formed respectively.

In the figure, the forward sloping ridge 5A and the backward sloping ridge 5B are formed on the lower surface of the shoe sole main body 2, 2'substantially entirely from the toe portion 3 to the heel portion 4. However, at least the toe portion 3 and the heel portion 4 may be partially provided with the front curve anti-slip projections 5A or the back curve anti-slip projections 5B to prevent slippage.

An embodiment of the present invention is configured as described above, and is used not only for relatively light movement such as walking, but also for sports, mountaineering, or fishing or on the construction site. When the person's feet are unstable and violent exercises with sudden force are performed, the bottom surface of the shoe sole main body 2, 2 ′ made of an elastic material such as rubber or synthetic resin is substantially aligned with the axis X. A large number of substantially arcuate lordotic anti-skid ridges 5A provided so as to bulge toward the toe portion 3 in the orthogonal direction use the conventional anti-slip formed by simply contacting the ground E with a straight line. Unlike the case, it bites into the ground E 2 in a substantially arcuate shape that bulges toward the toe portion 3 and grips the ground E firmly and stably. Therefore, the substantially arcuate lordotic ridge 5A prevents the user from reliably sliding backwards or falling forward while leaning during sports or climbing. At the same time, the forward sloping convex ridge 5A is formed in a substantially arcuate shape that bulges toward the toe portion 3 and firmly and stably bites the ground E, so that sliding in the left and right directions can be reliably prevented.

Moreover, a kyphosis is provided between any preceding lordotic anti-skid ridge 5A that goes from the toe 3 to the heel 4 of the sole body 2, 2'and a trailing lordotic anti-slip ridge 5A. Due to the arrangement of the anti-slip ridges 5B, the front sloping anti-slip ridges 5A and the back sloping anti-slip ridges 5B are crossed with each other at two points a and a'on the left and right which are substantially orthogonal to the axis X. , The leaflet-shaped surrounding small chamber part a surrounded by the lordotic anti-skid ridges 5A and the kyphosis anti-skid ridges 5B bulges toward the toe 3 on the inside of the lordotic anti-slip ridges 5A. It is formed at the approximate center of the main bodies 2 and 2 '(see FIGS. 1 and 3).

Further, in the substantially arcuate lordotic anti-skid ridge 5A that bulges toward the toe portion 3, a trailing kyphosis anti-skid ridge 5B is provided to the left and right of the surrounding small chamber part a. several chamber portions by sequentially substantially orthogonal to the ridges _{5A b 1, b 2, b} 3 ... is Ru are formed respectively. Therefore, for example, as shown in FIG. 3, an encircling small chamber portion a is provided on the inside of the substantially arcuate lordotic anti-slip projection 5A with diagonal lines, and several small chamber portions b ₁ are provided on the left and right sides of the enclosing small chamber portion a. , B ₂ , b _3, ... Are respectively formed, so that these surrounding small chamber portion a and several small chamber portions b ₁ , b ₂ , b ₃ ... It can be stopped securely. In addition, as a result of the enclosing small chamber portion a and the small chamber portions b ₁ , b ₂ , b ₃ ... Collecting, as a whole, for example, as shown in FIG. A strong bite is formed on the ground E in the tongue 5A, so that the user can surely prevent backward sliding during sports, climbing, etc., and the sliding causes the user to fall forward. Is reliably prevented.

Further, as shown in FIG. 1, a large number of substantially arch-shaped rear knee-skid convex ridges 5B bulging toward the heel portion 4 are formed in a direction substantially orthogonal to the axis X of the shoe sole bodies 2 and 2 '. Since this kyphosis convex ridge 5B digs into the ground E to form a substantially arcuate ridge on the ground E, it is a vigorous exercise in which momentary force is applied like sports or mountain climbing. As a result, it is possible to reliably prevent the vehicle from sliding forward, and to prevent the person from falling on his / her back due to the sliding, and to prevent lateral sliding.

Also, between any preceding lordotic anti-skid ridges 5A and trailing lordotic anti-skid ridges 5A, rear kyphosis anti-slip ridges 5B are arranged, for example, as shown by the diagonal lines in FIG. As a result, the front curve anti-slip projections 5A and the back curve anti-slip projections 5B are crossed at two points a and a'on the left and right of the axis X of the shoe sole bodies 2, 2 '. The leaflet-shaped surrounding small chamber portion a surrounded by the ridge 5A and the kyphosis convex ridge 5B is, for example, inside the kyphosis convex ridge 5B hatched in FIG. Is formed in the approximate center.

On the left and right sides of the surrounding small chamber part a, there are several small chamber parts b ₁ , b ₂ , b ₃ ... In the rear arched convex ridge 5B having a substantially circular arc shape with diagonal lines in FIG. 4, for example. When the shoe sole bodies 2 and 2 ′ are in contact with the ground E, the rear curved anti-skid projections 5B cause a substantially arcuate bite bulging toward the heel 4 on the ground E. It is formed. Then, the surrounding small chamber part a surrounded by the ridge 5B and the several small chamber parts b ₁ , b ₂ , b _{3 on} the left and right sides of the surrounding small chamber part a are finely grounded on the ground E. In contrast, a bite is formed.

In this way, even when performing a heavy exercise such as sports or mountain climbing, the substantially arched ridged ridge 5A that bulges toward the toe portion 3 and the substantially arched kyphosis that bulges toward the heel portion 4 A substantially arcuate bite is formed on the ground E by the non-slip projections 5B, and sliding is surely prevented.

In addition, in the above-mentioned embodiment, the front girth anti-skid projections 5A and the back girth anti-slip projections 5B are formed on the entire lower surface of the shoe sole bodies 2 and 2 ', but there is a possibility that they will come into contact with the ground E. Except for the less arched parts, only a part of the shoe sole main body 2, 2 ', for example, the front half part or the latter half part of the shoe sole main body 2, 2'has a lordotic ridge 5A and a kyphosis convex ridge 5B. Sliding may be prevented by forming a groove.

Further, in the above embodiment, the pair of shoe sole main bodies 2, 2 ′ has the anti-slip 5 formed by the front kyphosis anti-slip ridge 5 A and the rear kyphosis anti-slip ridge 5 B for sliding forward and backward. On the contrary, the front and rear anti-slip recesses are provided by providing a large number of front and rear anti-skid recesses in a direction substantially orthogonal to the axis X of the shoe sole main body 2, 2 '.
