Description

FOOTWEAR AND TIRE HAVING SLIDING PREVENTION PAD}

The present invention relates to a shoe and a tire to which a non-slip pad is attached, and more particularly, to prevent slipping by forming a friction particle layer on one surface of a pad having a membrane form that is easy to detach and attach, thereby increasing friction against the winter ground. The present invention relates to a shoe and a tire having an anti-slip pad, which can prevent various safety accidents.

In winter, after snowing, the ground forms an ice layer or a compacted layer of snow. These layers are quite slippery, and a fine layer of water is formed between the shoes as the pedestrian walks, and the water layer reduces the friction between the ground and the shoes, thereby always presenting the risk of safety accidents. In addition, in winter, as well as pedestrians, as well as tires of automobiles, the friction of the ground is reduced, and in order to prevent this, various chains or snow tires are installed as safety equipment to prevent this.

That is, the winter ground provides a very dangerous road surface condition for both pedestrians and vehicles, and a technique for preventing the same will be required.

To prevent this, various techniques have been proposed for pedestrians. In this regard, Korean Utility Model Publication No. 20-201986 increases the friction with the ground by attaching the whole or part of the velcro to the sole of the shoe, and has a small diameter of the cilia by rubbing against the ground by the cilia of the velcro. Is always pressed to the ground. Therefore, after a certain period of time, structural deformation occurs in the form of compression caused by the physical fatigue of the cilia, and there is a disadvantage of abrasion or deterioration that does not sufficiently correspond to the snow or ice layer of the road surface.

Of course, it is necessary to replace the Velcro function to reduce the friction before structural deformation or wear, but the action time of the frictional effect is too short, so there is a troublesome and uneconomical problem of frequent replacement.

Korean Utility Model Publication No. 1996-10493 is a technology that reduces friction with slippery road surfaces in winter by impregnating integrally by applying wear-resistant particles to the sole of a shoe.

However, this is also a structure that the sole and wear resistant particles are integrated when the wear resistant particles are impregnated into the sole of the shoe, so it is impossible to replace them after the cost increase and wear of the wear resistant particles by adding a separate process during manufacturing. There is a problem that the road surface is not damaged.

On the other hand, as a technology for preventing slipping with the road surface in winter, in the case of tires, spikes which selectively protrude by air pressure on the tread portion of the tire in contact with the road surface, as shown in Korean Patent Publication No. 1998-85501 Although there is a built-in number, it is necessary to apply a non-slip technology in the production of tires, so the cost of the inevitable rise of the tire has a disadvantage of lowering the unique performance.

The present invention has been proposed to prevent the above problems, an object of the present invention is to form a detachable attachment means between the shoe sole and the anti-slip pad formed with a friction particle layer to thereby increase the cost of manufacturing shoes It is to provide a shoe with an anti-slip pad that can be used faithfully to a non-slip function within a range that does not increase and prevent a pedestrian's safety accident.

Another object of the present invention is to form an attachment means that can be separated between the tire and the anti-slip pad formed with a friction particle layer to prevent slipping during driving of the vehicle thereby preventing safety accidents and easy use by easy attachment and detachment It is an object of the present invention to provide a tire with an anti-skid pad that can be easily and normally driven by the tire itself.

In order to achieve the above object, the present invention is formed of a base pad of a synthetic rubber material having a flexible elasticity and ductility, and a friction particle layer formed of wear-resistant friction particles impregnated on one surface of the base pad, and a pad body having a velcro formed at a periphery thereof. ; The pad body is characterized in that it comprises a shoe formed with a Velcro on the periphery of the sole to selectively attach and detach.

Another feature of the present invention is a base pad of a synthetic rubber material having a flexible elasticity and ductility and a friction particle layer formed of wear-resistant friction particles impregnated on one surface of the base pad has a membrane form that can be easily attached and detached can wrap the tire A pad body having a shape and having a velcro formed at a periphery thereof; The anti-skid pad is configured to include a tire having a ring-shaped or a plurality of separate velcro attached to both peripheral portions to selectively attach and detach.

Hereinafter, with reference to the accompanying drawings, the configuration of the subject innovation in detail as follows.

1 is a cross-sectional view showing the configuration of the pad body 100 of the present invention, the friction particle layer 120 is formed on one surface of the planar base pad 110 having a predetermined thickness. Here, the base pad 110 is formed of rubber or synthetic rubber having elasticity and ductility, and the pad body 100 may form a flat foundation and a solid shape in a free form.

Meanwhile, the friction particle layer 120 formed on one surface of the base pad 100 is integrally embedded in or fixed to the surface of the wear resistant friction particles 121 during the manufacture of the base pad 110. Such wear resistant friction particles 121 ) Is a wear-resistant metal oxide or natural mineral fine particles, it is preferable to have a variety of forms and excellent wear resistance.

However, when the friction particles 121 are coated, the particles of the rapid oxide and the natural mineral may form a predetermined ratio with each other.

Impregnation of the substrate pad 100 of the friction particles 121 has a process of distributing the friction particles 121 to one surface side during the manufacturing of the substrate pad 100 and integrating the rubber particles into vulcanizing or curing means. .

However, the formation of the friction particle layer 120 is not limited to the above method, but may also be achieved by curing the mixture of the adhesive material and the friction particles 121 having excellent adhesion.

The pad body 100 of the anti-skid pad can be freely cut and deformed in any form, and can be attached to all kinds of articles contacting various winter road surfaces.

As this application example and the attachment structure, as shown in Figures 2 and 3 in the case of the shoe 200 is formed around the velcro 220 wrapped around the sole 210, or a plurality of separate velcro 220 Form integrally.

On the other hand, the pad body 100 attached to the shoe 200 corresponds to the shape of the sole 210 of the shoe and at the same time to the Velcro 220 of the shoe 200 at the periphery of the pad body 100 cut slightly larger. Velcro 150 of the pad body 100 is formed at the position to be attached.

According to the present invention, the pad body 100 may be separated from the sole of the shoe when necessary. This is when the friction particle layer 121 of the pad body 100 is worn out and the product life is over, or when entering the room.

Meanwhile, in the case of FIG. 4A, the pad body 100 surrounds the entire sole 210, and in the case of FIG. 4B, the pad body 100 partially covers the sole 210.

When the pad main body 100 is applied to the shoe 200 as described above, a plurality of pad main bodies 100 are packaged to form a layer of friction particles so as to have different levels of friction in each individual.

When the non-slip pad of the present invention is applied to the tire will be described.

FIG. 5 illustrates that the anti-slip pad surrounds the tire, and forms a velcro 320 inside and outside from the side portion close to the rim side of the tire 300.

As illustrated in FIGS. 6A to 6B, the Velcro 320 may be formed in the shape of a ring in the side portion of the tire or may be separately formed in a plurality.

On the other hand, the pad body 100 is attached to the tire is formed in a form that can wrap the tread portion of the tire 300, as shown in Figure 7 wrap the entire tire 300 or viewed from the front of the tire 300 At the same time, it may be wrapped in three or four portions.

This is to adjust the degree of wrapping the tires in accordance with the slippery degree of the road, and to wrap a part of the detachable non-slip pad in other tires.

As described above, the present invention forms a layer of friction particles on one surface of a pad having an easily replaceable membrane, thereby increasing friction with respect to the winter ground, thereby making it easy to use and preventing various safety accidents.

That is, when attached to the sole of the shoe, the anti-skid pad of the present invention may have a hassle and anti-slip effect that must be frequently replaced as the friction particle layer has a certain wear resistance, and when worn or when walking on a general road surface Separation can also be done quickly and easily.

In addition, when the tire is attached to the tire, the driver can easily attach and detach the anti-skid pad between the slippery road surface and the tire in winter, thereby effectively responding to sudden weather changes.
