Description

Shoes with anti-slip material {Footwear fitted non-slip equipment}

In the present invention, an anti-slip device is mounted on the sole of a shoe so that the spike pin of the anti-slip device does not protrude to the outside, so that it can be used as a normal shoe in everyday life, and when working on slippery surfaces such as snowy or icy roads, the spikes of the anti-slip device are used. This relates to a shoe with an anti-slip part that prevents slipping by installing the anti-slip part in the opposite direction so that the fin protrudes outward, allowing safe walking on snowy roads, icy roads, seaside rocks, etc.

Generally, the soles of shoes or sneakers are made of rubber or synthetic resin, and various shapes of protrusions are formed on the bottom to prevent slipping while walking. However, on snowy or icy roads, etc., the sole has the problem of being easily slippery due to the material of the sole itself. there is.

When walking on snow-covered or icy roads in winter, you have to keep your balance and walk carefully every time you step to avoid falling, so it takes more time than usual and even if you are careful, you often slip against your will. As a result, the risk of injury is high and fatigue occurs more easily.

In particular, in the case of seashore fishing, there is a problem that the surface of the seaside rocks is very slippery, so ordinary shoes can easily cause injury.

Crampons are generally used as anti-slip devices worn on shoes to prevent slipping, but they are bulky and heavy, so they are not easy to carry on a daily basis, and when worn, they must be strongly tightened with a band against the bottom of the shoe, making them difficult to use in everyday life. It is not easy to use and is mainly used only when mountain climbing.

Two methods have been proposed to solve this problem of crampons.

First, as in Republic of Korea Patent No. 10-2122374, “Anti-slip device with selective emergence control” (registered on June 8, 2020), the lower part of the anti-slip device is able to selectively emerge from the shoe.

Second, as in Korea Registered Patent No. 10-1652234, “Shoes with Removable Anti-Slip Device” (registered on August 24, 2016), the anti-slip needle is worn inside the heel of the shoe to hide it, and when worn on snowy or icy roads, With a simple operation, you can prevent slipping by flipping the anti-slip needle bar in the opposite direction and joining it.

The present invention seeks to provide a shoe that can selectively use the anti-slip function by having the spike pin protrude to the outside or toward the inside of the shoe depending on the direction in which the anti-slip device is installed, as in the second method.

In the conventional case, such anti-slip devices have a relatively thick and sturdy shape, so they can mainly be installed only on the rear floor (heel side), and it is difficult to install them on the front floor (front heel side).

In addition, since the direction in which the anti-slip device is installed is changed, the anti-slip device according to the prior art must basically have a flat plate shape. However, if such a flat plate shape has a large area, it becomes a factor that interferes with smooth walking on the front floor. , when the flat plate shape has a small area, there is a problem in that the anti-slip function is significantly reduced.

Republic of Korea Patent No. 10-2122374 “Anti-slip device capable of selective emergence and release adjustment” (registered on June 8, 2020) Republic of Korea Patent No. 10-1652234 “Shoes with removable anti-slip devices” (registered on August 24, 2016)

The present invention was made to solve the problems of the prior art as described above. By mounting the anti-slip device on the sole of the shoe in the forward or reverse direction, the spike pin protrudes outward or the shoe, depending on the direction in which the anti-slip device is installed. We aim to provide shoes that can be turned inward and have an optional anti-slip feature.

In particular, the first anti-slip device of the present invention has a middle portion in the front and rear directions that can be bent, allowing natural walking while being placed very widely across the entire front bottom surface of the shoe sole.

In order to solve the above problem, the present invention includes a first body mounting groove formed concavely upward, a plurality of first spike pin grooves extending upward from the first body mounting groove, and the first main body mounting groove. a shoe body in which a first non-slip groove including a plurality of first locking protrusion grooves extending horizontally from the body seating groove is formed on the front bottom surface of the shoe sole; A first anti-slip main body that has a shape corresponding to the first main body mounting groove and can be bent in the middle portion in the front and rear direction, and a first anti-slip main body that protrudes from one side of the first anti-slip main body and is to be inserted into the groove for the first spike pin. It includes a plurality of first spike pins arranged to enable A first anti-slip device that can be coupled to the groove for the first anti-slip device in the forward or reverse direction; It includes a cross-sectional area reduction portion for bending, wherein the cross-sectional area is reduced so that the first anti-skid main body can be easily bent in the front-to-back direction.

The shoe having this non-slip member consists of a shoe body 300, a first anti-slip member 100, and a second anti-slip member 200.

A shoe sole 301 is provided at the lower part of the shoe body 300 as shown in FIG. 1. The type of shoe is not particularly limited.

As shown in FIG. 2, a first anti-slip groove 310 and a second anti-slip groove 320 are formed on the bottom surface of the shoe sole 301, respectively.

The first anti-slip groove 310 will be described with reference to FIGS. 3 to 5, especially FIG. 5.

The first anti-slip device groove 310 is for the first anti-slip device 100 and is formed on the front bottom surface of the shoe sole 301.

The first non-slip groove 310 includes a first body seating groove 311, a plurality of first spike pin grooves 312, a plurality of first locking protrusion grooves 313, and a first breakaway protrusion. Includes a groove 314.

The first body seating groove 311 is a relatively large groove formed concave upward so that the first anti-slip device main body 110 of the first anti-slip device 100, which will be described later, can be seated.

The first spike pin groove 312 is a space extending to the upper part of the first body seating groove 311 to accommodate the first spike pin 123 of the first anti-slip member 100, which will be described later. . A plurality of first spike pin grooves 312 are formed.

The first locking protrusion groove 313 is formed to extend in the horizontal direction from the first body seating groove 311 so that the first locking protrusion 112 of the first non-slip member 100, which will be described later, is detachably coupled. It is a groove shape. A plurality of first locking protrusion grooves 313 are formed with respect to the first body seating groove 311.

As the first locking protrusion 112 of the first anti-slip member 100 is caught in the first locking protrusion groove 313, the first anti-slip member 100 remains coupled to the shoe sole 301.

The first breakaway protrusion groove 314 is for providing a space where the first breakaway protrusion 111 of the first non-slip member 100, which will be described later, can be manipulated with a finger, and is a first main body seating groove ( 311) in the form of a relatively wide groove formed on one side.

The second anti-slip groove 320 is for the second anti-slip device 200 and is formed on the rear bottom of the shoe sole 301.

The second non-slip groove 320 also includes a second body seating groove 321, a plurality of second spike pin grooves 322, a plurality of second locking protrusion grooves 323, and a second breakaway protrusion. It includes a groove 324, and the description thereof includes a first body seating groove 311, a first spike pin groove 312, a first locking protrusion groove 313, and a first breakaway protrusion groove. Replaced with an explanation of (314).

Next, the first anti-slip area 100 will be described with reference to FIGS. 9 to 16.

The first anti-skid device 100 includes a first anti-skid device main body 110 formed with a first release protrusion 111, a plurality of first locking protrusions 112, and a plurality of first spike pin mounting portions 113; , It includes a first spike pin case 121, a first spring 122, and a first spike pin 123, which are respectively mounted on the first spike pin mounting portion 113.

The first anti-slip device body 110 has a shape corresponding to the first body seating groove 311. That is, the first anti-slip device body 110 has a shape that can be seated in the first body seating groove 311.

In addition, the first non-slip main body 110 is configured so that the middle portion in the forward and backward directions can be bent.

For this purpose, in the case of this embodiment, the middle portion of the first anti-slip device main body 110 in the front and rear directions has a cross-sectional area for bending in which the cross-sectional area is reduced compared to other parts so that the first anti-slip device main body 110 can be easily bent. A reduction portion 114 is formed.

In the case of this embodiment, three cross-sectional area reduction portions 114 for bending are formed along the front-back direction of the first anti-slip body 110, and are formed at three portions in the width direction, for a total of nine portions.

Figure 13 shows that the first non-slip body 110 can be bent in the forward and reverse directions centered on the cross-sectional area reduction portion 114 for bending.

Depending on the embodiment, it is possible to use a relatively soft material without reducing the cross-sectional area in order to enable the middle portion of the first anti-slip body 110 in the front-back direction to be bent. However, in this case, there is a problem that durability may be weakened because other parts are made of soft materials.

A first release protrusion 111 is formed on one side of the first anti-slip device main body 110, which can separate the first anti-slip device 100 from the shoe sole 301 by operating it with a finger.

The first breakaway protrusion 111 has a vertically symmetrical structure.

A plurality of first locking protrusions 112 are formed on the first non-slip body 110.

The first locking protrusion 112 protrudes from the first non-slip body 110 in the horizontal direction and is arranged to be detachably caught in the first locking protrusion groove 313.

As shown in FIG. 14 , a plurality of first spike pin mounting portions 113 are formed in the first anti-slip device body 110 .

Each first spike pin mounting portion 113 has a structure in which a spike pin through hole 113a is formed on one side and a spike pin case mounting hole 113b is formed on the other side.

Each first spike pin mounting portion 113 is provided with a first spike pin case 121, a first spring 122, and a first spike pin 123.

The first spike pin case 121 includes a spring support plate 121a that blocks the spike pin case mounting hole 113b, and a spring support plate 121a extending from the edge of the spring support plate 121a toward the spike pin through hole 113a. It includes a side wall (121b) forming the spring receiving space (121b-1) and a plurality of wedge-shaped separation prevention protrusions (121b-2) formed on the outer surface of the side wall (121b).

The wedge-shaped separation prevention protrusion 121b-2 has a structure that allows the first spike pin case 121 to be easily inserted into the spike pin case mounting hole 113b, while making it difficult to separate once inserted. .

A first spring 122 in the form of a coil spring is provided in the spring accommodation space 121b-1.

The first spike pin 123 includes an external protrusion 123b that protrudes forward across the spring support jaw 123a in the middle portion in the longitudinal direction and a spring guide 123c that extends rearward.

The spring support jaw 123a is a portion supported by the first spring 122.

The external protrusion 123b is a portion that extends forward from the spring support jaw 123a and protrudes outward through the spike pin through hole 113a.

The spring guide 123c is a portion that extends rearward from the spring support jaw 123a and is inserted into the axial center of the first spring 122.

In this way, the external protrusion 123b of the first spike pin 123 penetrates the spike pin through hole 113a and protrudes outward, thereby protruding from one surface of the first anti-skid body 110.

In addition, the external protrusion 123b of the first spike pin 123 is arranged to be inserted into the first spike pin groove 312 of the first non-slip groove 310.

This first anti-slip device 100 may be mounted in the first anti-skid groove 310 of the shoe sole 301 in the forward or reverse direction.

Figures 3 to 5 show a state in which the first anti-skid member 100 is mounted in the reverse direction in the first anti-skid groove 310, and Figures 6 to 8 show the first anti-skid member 100. It shows a state in which it is mounted in the forward direction in the first anti-slip groove 310.

3 to 5, when the first anti-slip device 100 is mounted in the reverse direction to the first anti-slip device groove 310, the first spike pin 123 is received in the first spike pin groove 312 and It does not protrude to the outside.

In other words, in this case, it can be used as normal shoes.

Meanwhile, as shown in FIGS. 6 to 8, when the first anti-skid member 100 is mounted in the positive direction in the first anti-skid groove 310, the first spike pin 123 protrudes toward the ground.

Therefore, this shoe can be used as an anti-slip shoe.

When this shoe is used as an anti-slip shoe, the first spike pin 123 protrudes from the lower part of the first anti-slip part 100, and the first spring 122 with elastic force is formed by the wearer's load when walking. When pressed, the first spike pin 123 is inserted into the first non-slip body 110, thereby preventing slipping.

Specifically, the first spring 122, which has elastic force, contracts on its own when the wearer's load or the first anti-slip device main body 110 meets a sharp part such as a seaside rock, and the first spike pin 123 creates the first anti-slip device. While being inserted into the globe body 110, when the wearer's load or the first non-slip globe body 110 leaves the sharp part, the state of the first spring 122 is restored and the first spike pin 123 is It returns to the state of protruding from the lower part of the first non-slip body 110 again.

In this way, the present invention has the effect of fundamentally preventing slipping on seaside rocks, snowy roads, icy roads, etc. due to the first spike fin 123, etc.

In addition, even if the first spike pin 123 comes into contact with the ground, damage can be minimized by the first spring 122.

In addition, the first anti-slip device 100 may be mounted in the forward or reverse direction in the groove 310 for the first anti-slip device of the shoe sole 301, and the first anti-slip device 100 has a forward and backward middle portion. Since it can be bent in any direction, regardless of whether the first anti-slip member 100 is mounted in the forward or reverse direction, the first anti-slip member 100 is gently bent in the front-to-back direction of the front bottom surface of the shoe sole 301. By naturally bending along the curved curve, the first anti-slip member 100 does not interfere with natural walking even when it is disposed over a very large area on the front bottom surface of the shoe sole 301.

The second anti-slip zone 200 will be described with reference to FIGS. 17 and 18.

The second anti-skid member 200 includes a second anti-skid main body 210 formed with a second release protrusion 211, a plurality of second locking protrusions 212, and a plurality of second spike pin mounting portions, and a second anti-skid member body 210. It includes a second spike pin case 221, a second spring, and a second spike pin 223, which are respectively mounted on the spike pin mounting portion 213.

The description of these is the first anti-skid main body in which the first breakaway protrusion 111 of the first anti-skid member 100, a plurality of first engaging protrusions 112, and a plurality of first spike pin mounting portions 113 are formed. (110), the first spike pin case 121, the first spring 122, and the first spike pin 123, which are respectively mounted on the first spike pin mounting portion 113, will be described instead.

However, the second anti-skid member 200 does not have an element corresponding to the bending cross-sectional area reduction portion 114 of the first anti-skid member 100.

That is, since the second anti-slip area 200 is installed in a relatively small area, it does not need to be bendable.

The description of the present invention described above is for illustrative purposes, and those skilled in the art will understand that the present invention can be easily modified into other specific forms without changing the technical idea or essential features of the present invention. will be. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
