There are many issues due to construction methods.

[0004]

Even when wearing snow-only shoes that are hard to slip against snow and ice, on a frozen road,
Injuries may occur due to slipping and falling. Also, with regular use of leather shoes and the like, slipping and falling can be dangerous even with sufficient care. In snowy and cold regions, where snowfall is frozen for several months per year, the development of a universal anti-slip device that is convenient for everyday life is awaited.

The present invention provides an anti-slip device for footwear which ensures a long-term safe walking by selecting an anti-skid device and shoes under any conditions and conditions in a mirror surface freezing zone of a frozen road and a pavement road for a long time in a cold region. Things. A non-slip tip metal fitting that uses a double embedding method for the retaining process by joining A and B, and enables joining by the difference between materials such as metal and non-metal, and ensures long-term safe walking. Is provided.

[0006]

In order to achieve the above object, an anti-slip device for footwear according to claim 1 is characterized in that a plurality of materials having different characteristics are formed by a predetermined construction method and treatment with the characteristics of the object. The problem is solved by the anti-slip device device configured by utilizing the function, and the plurality of materials having different characteristics refer to the substances described in 1 to 8 below. 1 Double-slip anti-slip metal fittings with special metal steel, sintered alloy, and ceramic embedded at the tip (1). 2 Non-slip base made of natural rubber or rubber-based resin. 3. Stainless steel spring plate (4) that is strong against rust and contributes to the restoration of bends, strains, twists, etc. during walking. 4. A three-way connecting device (7) which is a soft plastic molded product that connects a rubber-based non-slip mother body, a front-mounted sweetening tape (12), and a rear-mounted rubber tape (13). 5 Attached tape (12) for front attachment. 6. A retractable rear-mounted rubber tape (13) that measures the stability of the mounting of the non-slip device body. 7. Insole plate and packing of rubber-based resin to ensure the stability of the base body with built-in anti-slip metal fittings (1) and stainless steel plate and the safety of the grounding surface of footwear (6). 8 Tightening countersunk screws (5) for suturing the above members 1 to 7.

[0007] The double-embedding method of the tip of the non-slip metal fitting according to the second aspect of the present invention is a method of embedding the tip of the non-slip metal fitting (1) into the tip of the non-slip metal fitting (1). In this section, the slope processing of the tip portion of "B") is caused by the difference in the processing slope of A and B, compared to the portion in which the carbide body (hereinafter referred to as "A" in this section) is embedded. It is formed by caulking the remaining meat (43) of the meat cost of B.

According to the fifth aspect of the present invention, there is provided an anti-slip metal fitting and an appliance of an attachment type to be attached to a shoe, in order to maintain the object of anti-slip for a long period of time. Conventionally, in order to solve the problem by selecting a material that minimizes the deterioration of the function due to wear during use, a carbide body is disposed at the tip of the anti-slip device. In addition, a method of replacing anti-slip metal fittings was adopted to reduce the anti-slip function.

[0009] The non-slip tip fitting (1) is made of special steel, SK2,
SKD and post-processable forged or cut products are subjected to predetermined machining and heat treatment methods to finish around 60 degrees HRC, and the embedded double-structured anti-slip metal fittings (1)
Sintered alloy (ultra-hard) ceramics single substance is applied to the metal fittings parts, which have been machined to a general steel material, at the tip of the metal fittings (Fig.
4, FIG. 16) is subjected to secondary processing by a method such as press-fitting, caulking, welding, etc., and the hardness of the tip is used to be finished to about HV 1500 to 2000.

[0010] The metal plate built into the mother body for fixing the above-mentioned anti-slip metal fitting (1) at an intermediate position does not bend due to its own weight, and is responsible for correcting strains, twists, etc., and withstands repeated walking movements. A suitable material is a solid and light material, which is a stainless spring steel material of 0.8 to 1.0 t. The base material of the anti-slip material is desirably made of a rubber or a rubber-based resin capable of coping with low temperature, high humidity and freezing, and is made of a material that can be applied to severe conditions such as flexibility and frictional wear over a long period of time. Hard rubber-based resin was subjected to a predetermined mold forming process, taking advantage of the characteristics of shrinkable rubber, adopting a ratcheting method, and facilitating component replacement.

An insole plate was used for the purpose of protecting the mother body to which the anti-slip metal fitting (1) was fixed, and stabilizing the landing surface of footwear and the tightening screws while walking. A soft rubber-based resin is preferred for preventing soft adhesion with footwear, slippage of the non-slip body, and the like. (Fig. 9) The front mounting fixed tape to which the non-slip base is mounted is a male-female sweetening type resin yarn woven tape with easy detachability, and a simple detachable tape that is suitable for each footwear size. Used (FIG. 7).

In order to measure the safety of the slipper base and the stability of the footwear, a back-mounted band is used.
A suitable material is a rubber or a rubber-based resin that can freely contract in a long or short time. Next, the connecting parts connecting the rubber base, the front side mounting band and the rear side mounting band are made of a hard rubber or urethane as a material which is flexible and strong in order to conform to the irregular shape of each shoe and which can withstand extremely low temperatures. Based resins are preferred. In addition, a construction method was adopted in which the anti-slip device reversing device (10) adapted to the upper of the footwear of each size was connected to the rattle type connecting hole (11) of the rubber-based molding base (2).

[0013] A base insole preform incorporating a non-slip metal plate.
The countersunk screw (5) for sewing and tightening the thread may be a commercially available product of about 4 to 5 mm.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings based on embodiments. To connect the non-slip mother body, the front-mounted sweetening tape (12) and the rear-mounted rubber tape (13), an inguinal-type three-way connecting device (7) is used, and in addition, the anti-slip device connecting reversing device ( By adopting 10), the anti-slip device for footwear can be brought into close contact with the footwear, and can be adapted to the uppers of footwear having different sizes and angles.

The material is a soft resin molded wall thickness 2.5 mm,
Urethane-based resin is good at about 2 g in weight. The tip angle of the non-slip tip metal is about 70 to 90 degrees, and adhesion and solidification to a metal part peculiar to freezing are solved by the angle of the non-slip metal tip and the self-weighted load during walking (FIG. 4). , FIG. 10,
(Figure 16). This anti-slip body can replace individual parts of the rubber-based molded base (2), stainless steel spring steel plate (4), and rubber-based insole plate (3) by means of countersunk screws.
The anti-slip bracket (1) is designed to deal with wear, damage, etc.
A component attachment system has been made possible. The non-slip metal fitting (1) of the present invention has a large size to fit the size of the shoe.
Medium and small, that is, three types, about 12 mm in diameter, 10 mm in diameter, and 8 mm in diameter, have a hexagonal shape (Figs. 4 and 10), and the weight of a single product is 5
g. The shape is not limited to a hexagon.

A 4 mm general standard flat screw (5) was used as a fastening screw for suturing each member. Lightness is one of the conditions for long-term walking, which is the purpose of non-slip equipment,
In the present invention, about 18 members are used for both feet. For example, in a large standard, one foot is as light as about 140 g, and in a small standard, a target is 100 g per foot. The relationship between freezing and metal deposition and solidification at low temperatures is a challenge. This problem is to be solved by the three relations between the rubber-based resin matrix, the tip position (point) and the angle of the slip stopper, the conical shape and the own weight.

The metal plate receiving device embedded plate (35) shown in FIG.
We want to select a material that suppresses deformation due to heavy pressure by applying a predetermined press process to a spring steel material to make it about 1 mm thick. Metal fittings to be embedded in shoes should be made of a material that can withstand severe conditions such as extreme cold, corrosion, sewage, and temperature differences for a long time. As an example, a molded part such as a light metal aluminum-based press-fit die-cast or a glass fiber-containing holcarbonate resin such as reinforced plastic can be considered. In the case of aluminum die-casting, press-fitting such as pressing (FIG. 11B), and if certain conditions such as the strength of the screw for tightening the anti-slip fitting are satisfied, for example, integral molding of nylon-based resin is also possible.

In the shoe sole manufacturing process, the screw receiving protection bolt (32) is tightened when the anti-slip metal fitting or the anti-slip attachment tool is not used to protect the metal fitting receiving device (16) embedded in advance. Need to put. There are many types of anti-slip attachments, and the shape is not limited.
The combination of 12 rear anti-skid devices (20) and front anti-skid devices (21)
It is essential for anti-skid under conditions of snow, ice and severe road conditions. The front anti-skid device (21) has an essential effect for walking on a frozen slope. It also plays a large role in hiking.

The material of the anti-slip attachment device is a flat plate of stainless steel 1.0 mm to 1.2 mm corresponding to rust, corrosion, etc., subjected to press bending and bending, or processed into a predetermined shape, or integrated with a forged product. Uses a material that has been subjected to ultra-hard welding at the tip of the machined metal.
I want to raise it to around 0 degrees. This material can be SK2 or SKD. The shape varies depending on the application, but we would like to consider partially reinforced resin as a countermeasure against freezing chains attached to metals.

The cemented carbide body (18) at the tip of the anti-slip fitting is formed by subjecting a cemented carbide (sintered alloy) to processing according to the intended use and mounting it on the tip of a metal fitting or a tool by predetermined processing such as welding or crimping. It is an object of the present invention to maintain the function for a long time. Shoes with anti-skid devices (Figs. 13 and 14)
The bracket receiving device (16) is embedded in advance, and the shoe anti-slip device (17) or the shoe anti-slip attachment device has a detachable structure as necessary, and the shoe anti-slip device (17) or the rear anti-slip device ( 20)
The shape and size of the front anti-skid device (21) vary depending on the purpose and footwear.

Non-slip metal fitting (1) or anti-slip metal fitting for shoes (17)
By using the rear anti-slip device (20) and the front anti-slip device (21) together with the anti-slip attachment device for shoes, the anti-slip effect is further enhanced. Figure 13 shows a walker for fresh snow and deep snow attached to a given shoe, and a front side with a wearing belt (24).
This is an example of fixing with.

The shape is a reverse boat bottom type, and models with large, medium and small bottom areas are used depending on the weight of the user. The material is desirably a reinforced plastic or a rubber-based resin that can be lightly molded and has a high degree of freeze adhesion and insulation. Weight is 40g
I think about 50g. Fig. 15 shows an example of a general anti-slip device for shoes with a 180-degree reversing structure.The existing one uses general soft iron and induces slippage on frozen roads, especially on the mirror surface of paved roads. Although extremely dangerous, the present invention is intended to solve the problem by partially welding a super hard shoe anti-slip device to the reversing anti-slip device (39).

Although the material is partially metal, it is desirable to partially use a reinforced resin in order to avoid freezing and adhesion chains. FIG.
Is an example of a double-end embedding method of a non-slip metal fitting. A non-slip metal carbide tip (18) (hereinafter referred to as “A” in this section) and a non-slip metal fitting (1) (hereinafter referred to as “A”) In this section, it is referred to as "B".) The materials of the above) include metals and non-metals, metals and cast iron, non-metals and resins, non-metals and ceramics, and other combinations of materials having different bonding forms.
Many problems can be solved by adjusting the processing dimensions and the processing frequency of A and B, and by partially pressing (caulking) the remaining meat of FIG.

[0024]

Since the present invention is configured as described above, it has the following effects. The present invention
Concerning safe walking in cold regions, frozen pavement roads, mirror-surface frozen regions, and snow-covered roads, a structure and lightness that greatly contributes to the drastic reduction of accidents due to slipping and enables easy attachment and detachment of shoes and footwear. Especially for older people, women and women,
Significant contributions to the safe walking of the handicapped in winter.

According to the present invention, each part replacement when worn or damaged
The attachment construction method prevents disposables, restores function by replacing parts, and the elements corresponding to the purpose of slip prevention are:
The tip of the cemented carbide shown in FIGS. 4 and 10 has a structure that can withstand slippage for a long time, and the safety with respect to slippage is extremely high. Except for the purpose of slip prevention, the appearance of the shoe is not impaired, and the shoe returns to its original shape and can be used as a normal shoe. The anti-slipping element has a structure to prevent slipping at the tip of an extremely hard object shown in FIGS. 4, 10 and 12, and has extremely high anti-slipping force and safety.

The joining method of the cemented carbide (18) (hereinafter referred to as "A" in this section) and the metal tip (1) (hereinafter referred to as "B" in this section) shown in FIG. The following features and advantages result. 1 The work process is easy. 2 Regardless of individual differences in technology such as heating and technical skills.

(3) Since the working process is simple, the cost is low. 4 Degradation and destruction of A and B molecules by heating, pressurizing, etc.
There is no deformation. 5 For the incorporation of A, the quality for the purpose of retaining is extremely high and stable by selecting the material of B. 6. The work and equipment are the same as the jig and the press for the target product, and do not require processing accuracy and secondary auxiliary materials.

7 By the numerical machining of the inclination of A and B and the size and length of the shape of A, it is possible to increase or decrease the strength of the retaining of B according to the purpose. 8 The tip of the metal carbide fitting is extremely hard and sharp, and requires an appropriate rounding to avoid danger of use. As a side effect, since the tip of the anti-slip metal tip carbide body (18) is an extremely hard object, there is a concern about secondary pollution such as dust due to ground contact friction due to the anti-slipping action on roads, especially on paved roads. As for the matter, it is possible for the user to prevent it by detaching / attaching the work for several seconds according to the purpose.

In addition, the tip of the anti-slip device of the present invention requires caution because walking on a metal or an iron plate slips and invites danger.
