JPH05285004A - Antiwear structure of article for attaching to human body and shoes using the same - Google Patents

Abstract

PURPOSE:To provide an antiwear structure of an article for attaching to the human body such as shoes, protectors, etc., and shoes having the structure applied thereto by improving the antiwear property of portions liable to be broken or worn by the contact with the ground or others. CONSTITUTION:A globule layer formed of a flame sprayed hard material is characteristically attached to a wear guard position of an article for attaching to the human body or shoes. Since the hard material is spattered as fine globules 6 by the flame spray to constitute a globule layer as a lamination layer of the globules 6, the antiwear property of such position is improved by the hard porous globule layer. Also, the globule layer can follow up the kinetic deformation of the position to prevent the periphery from the breakdown. Since the globule layer gives the touch of aventurine hard and rough surface, the design can be improved by the unique external appearance and shoes are provided relatively economically only by adding a simple process.

[Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body-worn article such as shoes and protectors, which provides wear resistance to a portion which is easily damaged or worn out by contact with the ground or the like. The present invention relates to a structure and shoes to which this wear resistant structure is applied.

[0002]

BACKGROUND OF THE INVENTION For example, in soccer shoes, baseball shoes, and tennis shoes, the leather on the toes of the shoes becomes scratched and fluffed or worn out after many years of use. Also, in skating shoes, the insides of the left and right shoes collide against each other and wear down. In business shoes, for example, the heel of the driver's shoes wears down for a long time due to collision with the floor during acceleration or braking. In addition, even in rider wear, elbow pads and knee pads for various competitions, and baseball leggers, due to collision with the ground or the like, a part of the parts wears out much faster than the surroundings.

Therefore, conventionally, natural leather and artificial leather, which are relatively wear-resistant, resin plates, metal plates, etc., have been used in those parts of the body-worn article where wear is remarkable. However, even with artificial leather, wear is inevitable, and as a result of wear, the surface skin layer is peeled off,
Not only does the appearance deteriorate, but rainwater is more easily absorbed, and it becomes difficult to apply leather oil or wax. By the way, if a metal plate is provided, the wear resistance will be significantly improved, but it will become heavy and, of course, there is a danger that the end surface of the metal plate will cut the main body and the main body will be deformed. It had a decisive drawback that it could not follow. Further, even with the resin plate, it is unavoidable that the resin plate is worn out by being melted by frictional heat at the time of collision with the ground.

[0004]

[Technical Items Attempted to Develop] The present invention has been made in view of such a background, and improves the wear resistance of a portion of the above-described body-worn article which is desired to be protected against wear and yet cuts the surroundings. The present invention aims to provide a wear-resistant structure for body-worn articles, which can be improved in design in some cases without being damaged, and a shoe to which the wear-resistant structure is applied.

[0005]

[Constitution of the invention]

[Means for Achieving the Object] That is, the wear-resistant structure of the body-worn article, which is the first invention of the present application, has a droplet layer formed by spraying a hard material on the wear guard portion of the body-worn article. It is characterized by.

The shoe according to the second invention of the present application is characterized in that a droplet layer formed by spraying a hard material is deposited on the wear gart portion of the shoe. These inventions are intended to achieve the above object.

[0007]

According to the present invention, the droplet layer deposited on the wear guard portion is hard because the hard material flies into fine droplets by thermal spraying and is formed as a stack of the droplets. It is porous. For this reason, the wear resistance of the portion is improved, the deformation due to the stress due to the movement can be followed integrally with the portion, and the surroundings are not damaged.

Therefore, in a shoe to which this is applied, the wear resistance of the wear guard portion is improved without impairing the original function of the shoe. Further, since the droplet layer does not exhibit metallic luster but has a satin finish and has a hard and rough surface feel, it exhibits a unique appearance and gives a shoe a new design.

[0009]

EXAMPLES Next, the wear resistant structure and shoes of the body-worn article of the present invention will be described as soccer shoes and baseball leggers. FIG. 1 is a soccer shoe 1 as an example of a shoe to which the wear resistant structure of the body-worn article of the present invention is applied.
However, this one has a large upper part 2 and a sole part 3.
The upper part 2 is sewn with a tongue, a string, stripes for the purpose of various reinforcements, a toe guard 4 is provided on the toe part, and a heel guard 5 is provided on the heel part. ing. This toe guard 4 and heel guard 5
Is made of cowhide, which is natural leather.

In the soccer shoe 1 of the present embodiment, a hard material is sprayed onto the toe guard 4 and the heel guard 5 in the upper portion 2, so the spraying in the present invention will be described below. Thermal spraying is a technology that melts a wire or rod-shaped linear material or powder material at high temperature and sprays it as droplets on the object to be processed, forming a layered film of the droplets on the surface of the object to be processed. , Mainly known as a metal anticorrosion treatment means. There are various types of this thermal spraying, such as flame type, arc type, plasma type, etc., depending on the means for melting the material, and depending on the material form at that time, wire type, rod type, powder type, etc. Subdivided. Although any of them can be applied in the present invention, in the present embodiment, due to the materials of the toe guard 4 and the heel guard 5 in the upper portion 2 of the soccer shoe 1, the flame spraying method having a relatively low droplet temperature is used. went. In that case,
The droplet diameter and the number of passes are adjusted by adjusting the pressure and flow rate of fuel gas, oxygen, compressed air and the like. In addition, as the enforcement method, there are a stationary type and a manual type,
The stationary type enables mass production, and the manual type enables on-site work.

As the thermal spray material, generally, zinc, aluminum and alloys thereof, carbon steel,
Various metals such as low alloy steel, stainless steel, havit, molybdenum, brass, brass, aluminum bronze, manganese bronze, copper, nickel aluminite, monel, nickel, tin, lead, solder, wood alloy and ceramics can be used. ,
Since these are generally harder than the materials of the wear guard parts in body worn articles such as the toe guard 4 and the heel guard 5, most of them can be used as the hard material in the present invention. Among them, the droplet temperature, the occurrence of rust after being deposited as a droplet layer, the appearance of the droplet layer, such as color change,
It is selected after considering the balance between adhesion strength and cost. It should be noted that these hard materials may be sprayed directly on the wear guard part of the body-worn article, but if the adhesion or adhesion strength is insufficient directly, apply a primer or blast in advance. It is better to improve it, and it is also possible to devise such as stacking droplet layers of different materials.

In the soccer shoe 1 of the present embodiment, brass as a hard material is sprayed onto the toe guard 4 and the heel guard 5, and droplet layers 4a and 5b are adhered to the respective essential portions thereof.

Explaining this manufacturing method, the hard material may be sprayed on the cut leather of the toe guard and heel guard at the stage of parts before shoe making, but in the shoe making process, it is bent, Since it is curved, in the embodiment, it is performed after the shoes are made.
That is, as shown by the chain double-dashed line in FIG. 1, the thermal spraying device head H is opposed to the soccer shoe, and the toe guard 4 is covered with a mask M except for its main parts, while the thermal spraying device head H is slightly shaken. Sprayed all over. At this time, if the mask M is not in close contact with the main part of the toe guard 4 and is masked with a slight distance, the droplets will also leak to the surroundings, and the droplet layer can be deposited as if a gradient was applied. Further, if this is performed in close contact, a boundary with the surroundings is provided, and a clear droplet layer can be deposited. The masking may be performed by covering the periphery with the mask M as shown in the figure, or by taping the periphery thereof or applying a water-soluble paint that can be removed later, but the masking is not always necessary. At this time, brass, which is a hard material, flies into fine droplets 6 by thermal spraying, and a droplet layer 4a is formed as a stack of the droplets 6.
In addition, the droplet layer 5a is formed. Therefore, the droplet layers 4a and 5a are porous, and the surface thereof does not exhibit metallic luster, but has a satin tone and has a hard and rough surface feel. If the droplet layers 4a and 5a are too thick, the toe guard 4 and the toe guard 4 cannot be deformed at the time of landing or at the time of kicking or kicking, and there is a risk that the toe guard 4 and the heel will be peeled off. It is desirable that the heel guard 5 is applied as a layer having an appropriate thickness in consideration of the material and elasticity of the heel guard 5 and the degree of deformation of the site.

The soccer shoe 1 thus obtained can be used in the same sense as a conventional soccer shoe, because the soccer shoe 1 can be deformed in the same manner as a conventional soccer shoe in terms of weight rather than wearing a metal plate. it can. Still, because it is in a state of being hard and surface coated compared to conventional leather,
Abrasion resistance in those parts is improved, even when used for a long time, it is possible to avoid cutting and even wearing the cowhide of those guards as much as possible, absorbing rainwater from the toes and heels,
It is also possible to avoid jerky and jerky inside of the shoes. Further, the appearance of the droplet layers 4a, 5a in a satin finish and the contrast of the surroundings gives a unique appearance, and the soccer shoe 1 having a new design can be provided. Moreover, the soccer shoe 1 can be obtained at low cost because it does not require any modification to the conventional construction method and can be obtained by simply adding the above-mentioned simple steps to the conventional steps.

FIG. 2 shows another embodiment of the wear resistant structure of the body-worn article of the present invention, which is applied to a baseball leggers 7. The leggings 7 are large and have a knee pad 7
1. The three pieces of the resin plate 1, that is, the buttocks pad 72 and the instep pad 73 are connected by the woven cloth 8 on the back side, and tightened by the rubber band 9 whose one end is fixed to the pad, It's designed to be worn around your foot. These patch plates 71, 7
Both 2 and 73 are made of a semi-rigid or hard synthetic resin plate, and in this embodiment, the droplet layer 7a is attached to the projecting portion of the knee pad 71 which has the greatest chance of coming into contact with the ground. ,
The same effect as that of the above embodiment can be obtained.

Although the present invention has been described with respect to the soccer shoe 1 and the leggings 7, the present invention is not limited to these, and is applied to, for example, a sole portion of a shoe, specifically, a heel contact surface of a business shoe. , Without making a squeaky metal hitting sound like a conventional metal tack, reduce wear of the part, or apply to spikes and stud surfaces in golf shoes, soccer shoes, rugby shoes, etc., Improves wear resistance. In that case, if the spikes and studs are made of ceramics or a hard or semi-hard synthetic resin that is integral with the outer sole, if the droplet layer is deposited on the entire surface or by masking, then Of course, the wear resistance is improved, but it is easy to accept even those who have a stereotyped idea that "these protrusions must be made of metal." The secondary effect of stimulating purchasing power through Of course, it can be applied not only to these shoes, but also to wear, protectors, pads, supporters, etc., which often make contact with the ground.

Although the material of the wear guard portion has been described as cowhide and synthetic resin in the above embodiment, the material of the wear guard portion of the present invention is not particularly limited, and natural leather and the like can be used. Artificial leather, non-woven fabric, various rubbers such as natural rubber and butadiene rubber, polyethylene, polyurethane, polypropylene, polyvinyl chloride, polyvinylidene chloride, polyamide 6, polyamide 66, polycarbonate, polyimide, phenol resin, urea resin,
Various thermoplastics such as melamine resin, silicone resin, epoxy resin, unsaturated polyester resin, acrylic resin,
It can be applied to thermosetting resins and their modified, complex solid and solid to foamed ones by adjusting the hard material and thermal spraying conditions.
