Abstract

An anti-slip sole relates to the field of footwear, in particular to an anti-slip shoe. The road surface is slippery or slippery, and it is easy to fall; if you fall, it is easy to cause fractures. In order to reduce the probability of falling on slippery or slippery ground, the present invention designs a non-slip sole. The technical solution is: the toe and heel of the sole plate are a plane, slightly upturned, and the side of the sole plate of the toe and heel that touches the ground is a layer of soft rubber, and there are suction cups on the surface of the soft rubber; the suction cups are distributed on the sole The arc edge of the toe and heel of the board has air holes on the top of the suction cup; the arch of the sole board is made of soft rubber, and there are serrations on both sides of the arch. The beneficial effects of the invention are: the suction cup increases the adhesion with the smooth ground and reduces the risk of tripping; the suction cup has air holes, which speeds up the recovery of the suction cup and reduces the resistance of traveling.

Description

a non-slip sole

technical field

The invention relates to the field of footwear, in particular to anti-skid shoes.

Background technique

On rainy days, the road surface is relatively slippery and slippery; indoors, especially in shopping malls, people like to look beautiful, the surface of the tiles on the ground is smooth, clean and shiny, with a low coefficient of friction and easy to fall; modern people, lack of exercise, can't stand it The torment of falling can easily lead to fractures, especially in an aging society, where the number of elderly people is gradually increasing, and the elderly cannot afford it.

Contents of the invention

In order to reduce the probability of falling on slippery or slippery ground, the present invention designs a non-slip sole.

The technical solution adopted by the present invention to realize the purpose of the invention is: a kind of non-slip sole, which is characterized in that: the toe part and the heel part of the sole plate are a plane, slightly upturned, and the side of the sole plate of the toe part and the heel part contacting the ground is a plane There is a layer of soft rubber, and there are suction cups on the surface of the soft rubber part; the suction cups are formed of soft rubber, and the suction cups are distributed on the arc edge of the toe and heel of the sole plate, and there are air holes on the top of the suction cup; the arch of the sole plate is made of soft rubber, soft The rubber connects the front and rear parts of the sole plate. There are sawtooths on both sides of the arch of the foot. The sawtooth is composed of two pieces of sawtooth, one of which has multiple fixed holes at equal intervals, and the other has multiple equally spaced teeth. The protrusions on the sole match the fixing holes, rotate the arch of the foot plate, change the position of the zigzag, let the suction cups on the toe and heel touch the ground, or leave the ground.

The plane of the toe portion and the heel portion of the sole plate and the plane of the sole plate form 5-10 degrees, preferably 5 degrees.

The thickness of the rubber of the toe portion and the heel portion of the sole plate is 2-3mm.

There are 5-8 suction cups on the toes, 3-5 suction cups on the heel, the suction cups are 1-2mm above the rubber surface, the diameter of the suction cups is 1-2cm, the height is 3-5mm, and the curvature radius of the suction cups is 2cm.

The diameter of the air hole is 1-2mm, the air hole is obliquely pierced through the rubber layer, the angle is 30-60 degrees, the opening is on the outside of the suction cup, the diameter of the opening is 1cm, and the depth is 2mm; It is close to the level, from the inside of the air hole to the outside of the air hole, preferably at a downward angle of 5-10 degrees, so as to prevent the air hole from falling into dust, improve the patency of the air hole, and reduce the deposition of debris in the air hole.

The beneficial effects of the invention are: the suction cup increases the adhesion with the smooth ground and reduces the risk of tripping; the suction cup has air holes, which speeds up the recovery of the suction cup and reduces the resistance of traveling. the

Detailed ways

The toe portion 2 and the heel portion 6 of the sole plate 8 are slightly upturned, and are 5-10 degrees with the plane of the sole plate, preferably 5 degrees. The side of the sole plate 8 of the toe portion 2 and the heel portion 6 that contacts the ground is another layer of soft rubber. The thickness of the rubber layer is 2-3mm, and the rubber layer has a suction cup 1; the suction cup 1 is formed by the rubber layer, and the suction cup 1 is distributed on the arc edge of the toe part 2 and the heel part 6 of the sole plate 8, and the toe part has 5-8 suction cups 1 , there are 3-5 suction cups 1 on the heel, the suction cup is 1-2mm higher than the surface of the rubber layer, the diameter of the suction cup is 1-2cm, the center of the suction cup is depressed, the height is 3-5mm, the curvature radius of the suction cup is 2cm, and there are 2-4 air holes on the top of the suction cup 1 7. The air hole 7 has a diameter of 1-2mm. The air hole penetrates the rubber layer obliquely at an angle of 30-60 degrees. It opens outside the suction cup. The diameter of the opening is 1cm and the depth is 2mm. Some air holes are arranged horizontally along the edge of the shoe.

The foot arch portion 4 of the sole plate 8 is soft rubber, and the soft rubber connects the front and rear parts of the sole plate. There are sawtooth teeth 5 on both sides of the foot arch, and the sawtooth 5 is composed of two sawtooths. 1. The upper end is thick, and the junction of the thickness and thickness is sawtooth. One of the sawtooth has a plurality of equidistant fixing holes 3, and the other serration has a plurality of equally spaced protrusions to match the fixing holes. Rotate the arch 4 of the sole plate 8 to change the serration The position of toothing 5 can allow the suction cup 1 of the toe portion 2 and the heel portion 6 to contact the ground, or leave the ground.

When walking on a relatively slippery floor, rotate the zigzag 5 of the arch of the foot 4, let the suction cup 1 of the heel 6 and the toe 2 touch the ground, step on the foot, the suction cup 1 discharges gas through the air hole 7, and the suction cup 1 accommodates The gas is reduced. When the foot is lifted, the negative pressure inside the suction cup hinders the movement of the foot and prevents sliding, which can effectively reduce the chance of slipping. The negative pressure of the suction cup quickly sucks gas from the air hole, which is beneficial to reduce the forward resistance. The thickness of the air hole is the key to solving the problem. The air hole is small and the ventilation is slow, which hinders the forward movement; the air hole is too large and the suction is small, which cannot effectively prevent the slip.

When the ground is relatively rough, rotate the zigzag 5 of the arch of the foot 4 to allow the suction cup 1 of the heel 6 and the toe 2 to leave the ground, reduce the friction on the suction cup, and prolong the service life of the suction cup.
