Abstract

PURPOSE:To prevent the slippage even on a roadbed and a scaffold which are wet with water or oil by forming a resinoid grindstone layer on one face of a base plate, forming an adhesive agent layer on the other face, and sticking it to the bottom face of footwear through the adhesive agent layer. CONSTITUTION:As for a non-slip material 1 of footwear, a base plate 2 which becomes a main material is constituted of a sheet consisting of rubber gum. The base plate 2 is, for instance, a sheet of 1m width and >=10m length, an adhesive agent layer 3 is formed on the lower face, and the surface of the adhesive agent layer 3 is covered with peelable protective paper. This base plate 2 is blanked to a shoe sole shape by a blanking die, and a resinoid grindstone forming material is stuck to its surface, by which a grindstone layer 5 whose thickness is about 3mm is formed. When the protective paper is peeled off, the adhesive agent layer 3 appears, therefore, when the adhesive agent layer 3 is allowed to abut on the sole face of a sole member 8A of footwear 8 and pressed, the non-slip material 1 of the footwear can be stuck to the footwear 8. In such a way, even if a roadbed and a metallic scaffold are wet with rain or oil, abrasive grains 58... are penetrated into a stone and a metal and a frictional resistance become high, therefore, the slippage is prevented.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to non-slip footwear and anti-slip materials for footwear, particularly for preventing slipping from scaffolding at construction sites or sliding on smooth roads. related to footwear and anti-slip materials for footwear.

[Conventional technology]

Traditionally, frozen roads and snowy roads during winter are often slippery, so
Since ancient times, it has been practiced to attach anti-slip fittings to the bottom of setta, or to wrap ropes around long shoes. However, the bank. Hotel 1 Because the stone pavement of ordinary buildings and other buildings is polished to a shiny shine, water adheres to the roadbed on rainy days. It can become slippery and cause you to fall, but there is no way to prevent it from slipping. Even in general factories, conventional safety shoes do not have an anti-slip effect against oil and are dangerous in areas where oil is present, such as lvl steps, aisles, and mechanical equipment.

Furthermore, during the construction of a building, scaffolding is simply made of metal pipes, or a scaffold made of pipes with a landing made of metal plates, but these can become slippery when wet with rain or oil. This has become a source of concern in preventing industrial accidents. [Problem to be solved by the invention] As mentioned above, it is impossible to wear something like spiked shoes on a highly polished roadbed or scaffolding at a construction site, There is a problem in that even if the shoes have irregularities or are studded, they are useless in preventing slipping when the road surface or foothold is wet.

In view of such circumstances, this invention was developed with the aim of providing footwear that does not slip on roadbeds or scaffolding wet with water or oil, and an ffTh anti-slip material, without using metal fittings like studded shoes. It is something.

[Means to solve the problem]

In order to solve the above problems, this invention (1) forms a resinoid grindstone layer on one side of a substrate, forms an adhesive layer on the other side of the substrate, and adheres to the bottom surface of footwear through the adhesive layer. (2) Footwear, characterized in that a resinoid grindstone layer is formed on the bottom surface of the footwear.

A technical measure was taken.

[one action]

In the anti-slip material configured as described above, a resinoid grinding wheel layer of the same quality as the resinoid grinding wheel is formed on one surface of the substrate (resin sheet), so an adhesive layer is applied so that this resinoid grinding wheel layer is in contact with the road surface. When it is attached to the soles of footwear such as shoes through the adhesive, the resinoid grindstone layer will come into direct contact with the road surface or scaffolding even when walking on the road surface or climbing onto the scaffolding at a construction site.

Therefore, the resinoid grinding wheel layer contains abrasive grains in a binder made of hard synthetic resin, and the abrasive grains have a high hardness that can cut stones and metals, so they can be used on slippery roadbeds. Even if the abrasive grain is stone or concrete. It digs into the metal, so you won't slide around like you would if you were wearing spikes. Since the grains of the mana abrasive grain are single-patterned, it will not be noticeable even if there is a lag on the contact surface, and even if the binder resin of the whetstone forming material wears out, new abrasive grains will come out from below, so the anti-slip effect will be reduced. Since the abrasive grains are not damaged and the abrasive grains are less likely to be damaged, the footwear has excellent durability.

〔Example〕

Embodiments of the invention will be described based on the drawings.

FIG. 1 is a cross-sectional view of an anti-slip material of H material showing a first embodiment.

The anti-slip material 1 for footwear has a substrate 2, which is the main material, made of a sheet made of rubber. The substrate 2 is, for example, 1
It is a sheet with a width of 10 m or more and a length of 10 m or more.
An adhesive layer 3 is formed on the lower surface in the figure, and a removable protective paper 4 is adhered to the surface of the adhesive layer 3. This board 2
is punched out with a punching die into the shape of a shoe sole as shown in Figure 2, and a grindstone forming material is attached to the surface of the shoe sole to form a grindstone layer 5 with a thickness of approximately 3 cm.
is formed.

The adhesive layer 3 is formed using a generally known roller coating method, and the material may be any material as long as it has good adhesion to synthetic rubber, which is the material of shoe soles, shoes, etc. The above-mentioned whetstone forming material liquid is a general resinoid whetstone (for grinding)
Binding materials used for (e.g. phenolic resin) 5A
Common abrasive grains 5B... (diamond, carbon,
Boron nitride cubic diboron steel, diamond sand, etc. known abrasive grains)
The mixture is formed into a layer by applying with a spatula or molding, and is hardened by air drying in a drying room and then by hot air drying. When the adhesion between the material of the substrate 2 and the grinding wheel forming material is poor, a resin layer with good adhesion to both may be separately formed between the substrate 2 and the resinoid grinding wheel layer 5, and the surface of the substrate 2 may have irregularities. Alternatively, the adhesion of the resinoid grinding wheel layer 5 can be improved by forming holes. The substrate 2 may be made of any material such as woven fabric, leather, non-woven fabric, or resin sheet. The abrasive grains 5B can be exposed on the surface of the resinoid abrasive layer 5 by puff polishing or the like. That is, in the molding or spatula coating formation of the resinoid grindstone layer 5, the surface of the resinoid grindstone layer 5 becomes smooth and the abrasive grains 5B... are buried in the abrasive binding material (resin) fake. By grinding this resin to expose the abrasive grains 5B, the anti-slip effect is enhanced. In this embodiment v1 consisting of the above-mentioned oval structure, when the protective sleeve 4 is peeled off, the adhesive layer 3 is exposed. 8 bottom member 8^
By applying pressure to the bottom of the footwear, the anti-slip material 1 of the footwear can be adhered to the footwear 8. As a result, when this footwear 8 is worn, the abrasive layer 5 comes into contact with the ground, roadbed, scaffolding, etc., and since the abrasive grains 5B... are harder than stones or metals, the abrasive grains 5B... Even if it is slippery due to rain or oil, the abrasive grains 5B bite into the stone or metal and have a high friction resistance, which prevents slipping. 4 to 6 relate to a second embodiment of the anti-slip material for footwear. In the anti-slip material 1 for footwear in this second embodiment, nylon cloth is used as the sheet-like substrate 2. The nylon cloth is immersed in an epoxy resin solution for reinforcement, taken out and dried, and as shown in cross section in FIG. A reinforcing layer 2B made of epoxy resin material is formed.

As a result, a grindstone layer 5 having a thickness of approximately 1.5 mm is formed on one surface of the substrate 2.As described above, the grindstone layer 5 consists of abrasive grains in the liquid of the bonding material 5 of the resinoid grindstone. A layer of grindstone forming material mixed with 5B... is formed by a roller coating process and heated and dried, and has the same hardness as a grinding wheel.Therefore, in its current state, it looks like a hard plate. Since it is difficult to adhere to the bottom surface of footwear 8, countless fine cracks 6 are forcibly formed in the resinoid grindstone layer 5 by a cracking treatment device 7 using a rolling roller as shown in FIG. (See FIG. 7).As a result, the anti-slip material 1 of this footwear recovers the flexibility of the substrate 2, and also has one surface with high hardness due to the resinoid grindstone layer 5. Surface and H object to be bonded 8
The above-mentioned first implementation can be carried out by applying an adhesive to the bottom of (boots, work safety shoes, leather shoes, athletic shoes, slippers, sandals, etc.) and adhering the fill anti-slip material 1 to the bottom of the footwear 8. As in the example above, sufficient anti-slip effects can be obtained on roadbeds and scaffolding that are slippery due to oil or water. In this embodiment, the material fiber 2^ is made of nylon thread, but it is not limited to this, and it is of course possible to use, for example, glass fiber, carbon fiber, cotton thread, etc. The shape of the pot used for the anti-slip material 1 may be shoe sole shape, thin tape shape, heart shape, or any other shape.

Figures 8 to 10 relate to a third embodiment of the i-product anti-slip material.

The substrate 2 of the anti-slip material 1 for footwear in FIG. 8 has a thickness of about 8 mm.
A nonwoven fabric made of nylon fibers was used. When the substrate 2 made of the non-woven fabric is immersed in the grindstone-forming material liquid, taken out and dried with hot air, a resinoid grindstone layer 5 is formed on the surface of the material fibers 2^ forming the non-woven fabric of the substrate 2, as illustrated in FIG. is formed. Therefore, in this state, the substrate 2 itself serves as a hard porous grindstone.

Therefore, a club king processing device 7 as illustrated in FIG.
When the material fibers 2A forming the substrate 2 are subjected to the softening treatment under pressure, numerous fine cracks 6 are formed in the resinoid grindstone layer 5 on the surface of the material fibers 2A forming the substrate 2, as shown in FIG.
This restores the flexibility of the material fibers 2^, so the nonwoven fabric substrate 2 itself retains its flexibility, and since the resinoid grindstone layer 5 is exposed on the surface, it can be shaped into the desired shape and size. By cutting it and gluing it to the bottom of the footwear, the anti-slip effect described in the first embodiment can be obtained. Although nylon was used as the material fiber in this example, it is not limited to this. When using a nonwoven fabric made of cloth or cotton as the substrate 2, for reinforcement,
For example, a reinforcing layer 2B as illustrated in FIG. 5 can be formed in advance on the surface of the material fiber 2A by immersion in an epoxy resin liquid or by spray coating.

Further, in this embodiment, as in the first embodiment, an adhesive layer can be formed on one surface of the substrate 2 and the protective paper 4 can be pasted thereon.
