Description

Stretch-proofing sports shoes

Technical Field

The utility model relates to the technical field of sports shoes, in particular to a stretch-proof sports shoe.

Background

When people wear the sports shoes to exercise, the sole part of the sports shoe sole is often required to be bent and deformed. In particular, when people do rope skipping, the bending deformation frequency of the sole part is higher.

Referring to fig. 1, when the sole of the sports shoe is deformed by bending, the longitudinal fibers of the upper portion of the sole are compressed and shortened as a compression zone 8 according to the concept of bending with respect to materials in the material mechanics; the longitudinal fibers of the lower part are stretched in tension, being the tension zone 7. While the middle is provided with a layer of longitudinal fibers which are neither elongated nor shortened and which retain their original length, this layer of fibers is called the neutral layer 9, and the stress on the neutral layer 9 is zero.

In the bending of the sole, the stresses to which the parts of the sole are subjected (tensile/compressive stresses) are distributed linearly along the interface height, the more distant the neutral layer 9 is, the greater the stresses to which they are subjected (tensile or compressive stresses).

Therefore, when the sole portion 12 of the sports shoe makes a bending motion, the bottom portion of the sole is repeatedly subjected to a large tensile stress. In the prior art, soles of sports shoes are mostly made of rubber materials. When the rubber receives repeated large tensile stress for a long time, the aging phenomenon is easy to occur. So that the bottom of the sole portion 12 is stretched to break, thereby affecting the quality and service life of the product.

Detailed Description

The utility model is described in further detail below with reference to fig. 2-5.

The embodiment of the utility model discloses a pair of stretch-proof sports shoes. Referring to fig. 2, the stretch-proof sport shoe includes a sole body 1, and an upper body 2 provided on the sole body 1. In this embodiment, the stretch resistant sport footwear is primarily intended for rope skipping. Referring to fig. 3, the upper body 2 includes, in order from the toe portion to the heel portion, a toe portion 11, a sole portion 12, an arch portion 13, and a heel portion.

Stretch resistant sport footwear is required to meet the wearer's daily walking needs in addition to the sport needs of the wearer.

Referring to fig. 3, along the length direction of the sole body 1, a plurality of protrusions 3 are provided at intervals in the sole portion 12, and the protrusions 3 are provided on both sides of the sole portion 12. When a wearer walks, the lugs 3 at different positions are in friction with the ground to improve the ground grabbing force of the sole body 1, so that the occurrence of slipping of the sole body 1 and the ground is reduced, and the daily walking requirement of the wearer is met.

Specifically, the lugs 3 include a first lug 31, a second lug 32, and a third lug 33 in this order from the toe to the heel. The first bump 31 is disposed on one side of the sole portion 12 near the beveled portion; the third bump 33 is disposed on the side of the sole portion 12 close to the group publication side; the second bump 32 is disposed between the first bump 31 and the third bump 33.

When the foot of the wearer just leaves the ground, the foot of the wearer is kicked back. At this time, the third protrusions 33 have a large friction with the ground, thereby providing a stable force to the wearer.

Thereafter, the wearer's foot is bent forward and forced rearward. In contrast, the sole portion 12 of the sole body 1 is also deformed by bending, and at this time, the first protrusion 31 located in the middle of the sole portion 12 has a large friction with the ground, thereby providing a stable force to the wearer.

Finally, when the foot of the wearer is about to leave the ground, mainly the front end of the sole portion 12 of the upper body 2 comes into contact with the ground. At this time, the first bump 31 will provide a stable force to the wearer that assists in its advancement.

In summary, the first protrusion 31, the second protrusion 32, and the third protrusion 33 are disposed at different positions of the sole portion 12, so that the grip of the sole body 1 on the ground is improved, and the use experience of the wearer is improved.

When the wearer jumps the rope, the toe 11 of the wearer first contacts the ground; after that, the sole portion 12 of the wearer starts to bend, and the front end portion of the sole portion 12 contacts the ground; then, the heel 14 of the wearer continues to move downward, and the contact area of the sole 12 with the ground becomes large; finally the foot of the wearer is kicked up to leave the ground.

Referring to fig. 3 and 4, a plurality of sipes 5 are provided at intervals along the longitudinal direction of the sole body 1 in the intermediate region of the sole portion 12. The pit lines 5 break the continuity of the bottom of the sole part 12, so that when the sole part 12 is bent by the same amplitude, the tensile stress born by the bottom of the sole part 12 is obviously reduced, and the conditions of ageing and cracking of rubber at the bottom of the sole part 12 are reduced, compared with the sole body 1 without the pit lines 5.

After the sole portion 12 is provided with the grooves 5, the bending stress portion of the sole body 1 is mainly a partial area on the grooves 5, and the neutral layer 9 of the sole body 1 bending upwards moves. At this time, the distances from the edge of the tension zone 7 at the upper part of the neutral layer 9 and the edge of the compression zone 8 at the lower part of the neutral layer 9 to the neutral layer 9 are reduced. Thereby reducing the tensile stress at the edge of the tension zone 7 and further reducing the occurrence of aging and cracking of the rubber sole body 1 at the bottom of the pit 5.

Referring to fig. 4, the tension zone 7 at the upper portion of the pit 5 is further provided with a tension member 6. When the rubber material of the tension zone 7 is tensioned, the tension member 6 shares part of the tension force, and reduces the tensile stress to which the rubber material is subjected. In this embodiment, the tension member 6 is a glass fiber grid woven from glass fibers having good tensile properties.

Further, referring to fig. 3, the sipe 5 is provided with a curved portion 101 toward the toe, and the curved portion 101 is away from the outside of the upper body 2. Therefore, when the sole part 12 rubs with the ground, the grooves 5 arranged in an arc shape can reduce the torsion degree of the sole body 1 positioned between the adjacent grooves 5, and the use safety of a wearer is improved.

And when the wearer jumps the rope, the main force-generating position of the wearer landing and jumping is the inner side of the sole portion 12. Therefore, the inner side of the sole portion 12 corresponding to the upper body 2 is also stressed more, and the bending portion 101 of the dimples 5 is arranged in the inner side area close to the upper body 2, so that the torsion degree of the sole body 1 between the dimples 5 can be further reduced, and the use safety of a wearer can be improved.

When the wearer jumps the string, mainly the ball portion 12 of the wearer contacts the ground, and the center of gravity of the wearer is inclined forward. At this time, the first protrusions 31 of the forefoot portion 12 come into contact with the ground, thereby assisting the wearer in landing and jumping.

Referring to fig. 3 and 5, at the same time, in order to increase the frictional force between the upper body 2 and the ground when the wearer lands, the stability of the wearer when lands is improved. The first bump 31 is provided with a first inclined surface 4 on a side near the toe cap, and when the wearer lands on the ground, the first inclined surface 4 is also in contact with the ground, thereby improving the frictional force of the ground against the upper body 2. And the bottoms of the first inclined plane 4 and the convex blocks 3 are respectively provided with an anti-skid convex line so as to further improve the acting force between the upper body 2 and the ground.

The above embodiments are not intended to limit the scope of the present utility model, so: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
