Patent Document 1 discloses a sock in which a urethane foam sponge (5) having cushioning and non-slip properties is attached to the inner surface of the heel (4) of the sock.
Patent Document 2 discloses a sock in which a reinforcing material (2, 3) made of polyurethane foam is provided on the back side of the sock.
In Patent Document 3, a sheet-shaped urging member (5) having several through holes (21) is provided on a part of the upper surface of the insole main body (2), and the urging member (5) penetrates. An insole provided with a non-slip member (4) at a position below the opening of the hole (21) is disclosed. In this insole, when a load is applied to the insole main body (2), the upper surface of the non-slip member (4) comes out at a position higher than the upper surface of the insole main body (2) via the urging member (5). By coming, it exerts a non-slip effect. On the other hand, when no load is applied, the non-slip member (4) does not receive the frictional force, so that the footwear can be taken off and put on smoothly.
Patent Document 4 discloses a sock in which the lower surface and the inner surface of the sole of the sock body are non-slip.
Patent Document 5 discloses a sock in which an inner non-slip surface portion (3i) is provided on the inner surface of the sock main body (2) and an outer non-slip surface portion (3o) is provided on the outer surface.
Patent Document 6 discloses a shoe insole and a shoe in which a shock absorbing material or a non-slip material is arranged on the shoe or the insole.

However, in the above-mentioned Patent Documents 1, 2, 4 to 6, it is possible to prevent the feet and the like from slipping by providing the non-slip material, but on the other hand, the feet and the like are socks and shoes. There was a problem that the foot could not be smoothly put into shoes or socks due to the non-slip material when putting it in.
On the other hand, in the case of Patent Document 3, the non-slip member (4) and the urging member (5) can prevent the foot from slipping and smoothly put the foot in. However, although the urging member (5) is a seat member having a cushioning property, in order to allow the non-slip member (4) to come out from below through the opening of the through hole (21), the urging member (5) has a sheet shape. The urging member (5) of the above requires a certain degree of hardness. Therefore, there are the following problems.
First, such a stiff urging member (5) cannot be applied to the entire surface of the insole. When applied to the entire surface, the insole itself tends to become hard and uncomfortable to wear.
Secondly, the sheet-shaped urging member (5) provided with such a large through hole (21) requires an area of a certain amount or more, and it is difficult to finely apply it to a narrow local area.
Thirdly, as described above, since the urging member (5) requires a certain degree of hardness, it tends to lack cushioning properties, and when such an urging member (5) is applied to socks or the like, the socks are in a rigid state. It becomes.

Patent Document 7 is a technique provided by the present inventor as a solution to the problems of Patent Documents 1 to 6. The structure is such that a good-slip net body (12) is stretched over the non-slip cushion material (11) to ensure ease of wearing, and the contact parts such as feet and hands rub against the fabric. It is designed to prevent the occurrence of beans and inflammation.
However, in the case of the technique shown in Patent Document 7, since the net body (12) is stretched around the cushion material (11) and attached, there are the following problems.
A. A separate sewing process for sewing the net body (12) to the cushion material (11) is required. Therefore, a lot of manpower and time are required for production.
B. When the cushion sheet in which the net body (12) is sewn is cut into a foot shape or the like to obtain a product, the net body (12) can be unraveled at the cut edge, so such a simple method cannot be adopted. That is, since the edge portion of the cut net body (12) is easily frayed, it is necessary to cut the cushion material (11) into a product shape in advance, sew the net body (12), and overhang the edge.
C. In order to ensure that the entire net body (12) is in full contact with the cushion material (11), it is necessary to make the sewing seams finer. When the seams of sewing are roughened, the contact surface of the net body (12) with respect to the cushion material (11) becomes rough, and it becomes difficult to exert the function.

Therefore, the present invention solves the above-mentioned problems of the prior art, is easy to manufacture, can be done in a short time and at low cost, and makes it easy to put the feet and hands in and out of shoes, socks and gloves. In addition, once inserted, the soles and palms of the feet can be brought into contact with shoes, socks, and gloves without moving, thus preventing the occurrence of blister and inflammation due to friction. The challenge is to provide a skin contact sheet that can be used.

It is configured as the outermost surface of the contact surface with, and is configured as a smooth slippery surface on which the human body portion is slippery, and the second surface is configured to be lower than the first surface with a small step. At the same time, the human body part is formed on a non-slip surface that is hard to slip on it, and the skin contact sheet has a first surface with respect to the second surface when a certain amount of vertical pressure is applied from the contacting human body part. The first feature is that the human body part is configured to be in contact with the second surface by being relatively submerged, and thus the human body part is configured to be immobilized on the second surface.
Further, in addition to the above-mentioned first feature, the skin contact sheet of the present invention includes an elastic sheet body made of an open cell type foamed resin, and the elastic sheet body has a surface uneven pattern layer on the upper surface thereof. The second feature is that the convex surface of the surface uneven pattern layer is formed on the first surface and the concave surface of the surface uneven pattern layer is formed on the second surface.
Further, in the skin contact sheet of the present invention, in addition to the above-mentioned second feature, the surface uneven pattern layer is formed by printing a good-slip printing layer on the upper surface of a non-slip elastic sheet body, and the printing layer is formed. The third feature is that the upper surface of the elastic sheet body is the first surface and the upper surface of the elastic sheet body without the printing layer is the second surface.
Further, in the skin contact sheet of the present invention, in addition to the above-mentioned second feature, the surface uneven pattern layer is formed by forming the upper surface itself of the non-slip elastic sheet body into an uneven structure, and is a convex surface of the uneven structure. The fourth feature is that the convex surface of the surface uneven pattern layer is surface-treated to obtain a smooth surface, and the concave surface of the surface uneven pattern layer, which is a concave surface of the uneven structure, is used as it is as a non-slip surface.
Further, in addition to the above-mentioned fourth feature, the skin contact sheet of the present invention is characterized in that only the convex surface of the surface uneven pattern layer, which is the convex surface of the concave-convex structure, is printed to obtain a smooth-slip printed surface. There is.
Further, in the skin contact sheet of the present invention, in addition to the above-mentioned first to fifth features, the first surface is formed as a linear pattern (including points), and the line width W is 1.0 to 1.0 to. The range of 6.0 mm, the distance L between adjacent lines in the direction perpendicular to the direction in which the human body parts such as the sole and palm move forward and backward is in the range of 2 to 20 mm, the line width W of the linear pattern and the distance L between adjacent lines. The sixth feature is that the ratio W / L of the above is in the range of 1/20 to 1/1, and the step D between the first surface and the second surface is in the range of 0.1 to 3.0 mm. ..
Further, in addition to the above-mentioned first to sixth features, the skin contact sheet of the present invention has a seventh feature that it is arranged on the inner bottom of the sock and becomes a part of the sock.
Further, in addition to the above-mentioned first to sixth features, the skin contact sheet of the present invention has an eighth feature that it is arranged on the inner surface of the palm side of the glove and becomes a part of the glove.
Further, in addition to the above-mentioned first to sixth features, the skin contact sheet of the present invention has a ninth feature that it becomes a shoe insole or a part of the insole.
Further, in addition to the above-mentioned first to sixth features, the skin contact sheet of the present invention has a tenth feature that it becomes an inner sole or a part of the inner sole of shoes.

According to the skin contact sheet according to claim 1, the surface for contact with the human body portion is composed of two types of surfaces, a first surface and a second surface, the first surface is the outermost surface, and the human body portion is the outermost surface. It has a slippery surface that is slippery on the top. Therefore, when the human body part is in contact with only its first surface, the human body part can easily slide on the first surface. On the other hand, the second surface is a surface that is lower than the first surface with a small step, and is made into a non-slip surface on which the human body portion is hard to slip. Therefore, when the human body portion also comes into contact with the second surface, the human body portion as a whole is prevented from slipping by the second surface.
The skin contact sheet is made of an elastic body, and when a certain amount of vertical pressure is applied from the contacting human body part, the first surface sinks relative to the second surface, so that the human body part becomes the second surface. Since it is configured so that the human body part is immobilized on the second surface, the immobilization of the human body part in contact is ensured by applying a certain vertical pressure or more. Can be done. This makes it possible to eliminate the contact friction of the human body parts that come into contact with each other.
In addition, since the skin contact sheet has breathability as a whole, moisture and hot air generated from the human body part that is actually in contact with the sheet should be dissipated and removed through the skin contact sheet without adversely affecting the human body part. Can be done.
For example, when the foot is being inserted into the sock, the pressure in the vertical direction to the skin contact sheet is not yet applied, and the pressure is applied exclusively in the direction of sliding on the skin contact sheet. It slides in contact with the first surface but with little contact with the second surface, and the insertion is achieved.
On the other hand, when the weight or the like is applied after the insertion of the foot into the sock is completed, the vertical pressure from the sole of the foot is applied to the skin contact sheet. As a result, the first surface sinks and there is no step with the second surface, and the sole of the foot also contacts the second surface. As a result, the back surface of the foot is restrained in a close contact state on the non-slip second surface, and is immobilized, that is, immobile.
By immobilizing the human body portion in contact with the second surface, it is possible to eliminate the occurrence of friction on the human body portion and sufficiently prevent the occurrence of inflammation, beans and the like.
In addition, as described above, since the skin contact sheet is made of a breathable material as a whole, moisture such as sweat and hot air generated from the human body are quickly dissipated through the skin contact sheet. Can be removed.
In the case of the skin contact sheet according to claim 1, the surface itself of the skin contact sheet that comes into contact with the human body is the first surface and the first surface having different heights, instead of sewing by stretching something like a net body on the main body. Since it is composed of two types of surfaces, that is, it is possible to completely eliminate the troublesome work and the troublesome work for sewing the net body and the like.
Further, in the case of the conventional configuration in which the net body or the like is sewn and attached, the net body cannot be fixed in a sufficiently close contact state with the upper surface of the skin contact sheet unless the sewing seams are made fine. , There is a problem that defects are likely to occur in the function as a product, such as the edge of the cut net body being easily loosened. However, in the skin contact sheet of the present invention, since the contact surface itself of the skin contact sheet that comes into contact with the human body is composed of the first surface and the second surface, the use of the net body causes functional defects, quality defects, and productivity. All the problems of defects can be solved.

According to the skin contact sheet according to claim 2, in addition to the action and effect of the configuration according to claim 1, the skin contact sheet includes an elastic sheet body made of an open cell type foamed resin, and the elastic sheet. Since the main body has a surface uneven pattern layer formed on the upper surface thereof, the convex surface of the surface uneven pattern layer is formed as the first surface, and the concave surface of the surface uneven pattern layer is formed as the second surface.
By using an elastic sheet body that is breathable by itself, breathability can be ensured from the entire area through micro open cells.
Then, by utilizing the surface uneven pattern layer formed on the upper surface of the elastic sheet body, the convex surface is formed on the first surface and the concave surface is formed on the second surface, so that the skin contact sheet has a very simple structure and structure. It can be manufactured, and it is possible to eliminate a process such as a sewing process of a net body, which is prone to defective products and takes time and effort.
In addition, since the elastic sheet body, which substantially occupies most of the skin contact sheet, is made of open cell type foamed resin, sweat and moisture generated from the human body part through the micro open cells of the elastic sheet body. It can be quickly and surely dissipated through.

According to the skin contact sheet according to claim 3, in addition to the action and effect of the configuration according to claim 2, the surface uneven pattern layer is a slippery printing layer on the upper surface of the non-slip elastic sheet body. The upper surface of the printing layer was used as the first surface, and the upper surface of the elastic sheet body without the printing layer was used as the second surface.
By simply printing a good-slip printing layer on the upper surface of the non-slip elastic sheet body, a skin contact sheet having a surface uneven pattern layer can be easily and surely produced with a very simple structure. And since the first surface and the second surface can be easily and stably obtained in the simple structure, good function and stable quality can be exhibited as a skin contact sheet.
In addition, the width of the surface patterns on the first surface and the second surface, the distance between the patterns, their ratios, etc. can be accurately produced to a predetermined value by printing, and good functions can be stably exhibited. it can. Similarly, by changing the thickness of the print, the step between the first surface and the second surface can be adjusted very easily.

According to the skin contact sheet according to claim 4, in addition to the above-mentioned second feature, the surface uneven pattern layer is formed by forming the upper surface itself of the non-slip elastic sheet body into an uneven structure, and the uneven structure. The convex surface of the surface uneven pattern layer, which is the convex surface of the surface, was surface-treated to obtain a smooth surface, and the concave surface of the surface uneven pattern layer, which is the concave surface of the uneven structure, was used as it is as a non-slip surface.
The surface uneven pattern layer on the upper surface of the skin contact sheet can be obtained by the uneven structure of the upper surface of the elastic sheet body itself, which is the main component of the skin contact sheet, and has an advantage that no other material is required. The uneven structure can be obtained by embossing or the like. The concave surface of the concavo-convex structure may be used as it is as the non-slip second surface, and only the convex surface of the concavo-convex surface may be surface-treated to obtain a good slippery first surface. The smoothness of the convex surface can be improved by chemical treatment or physical treatment.

According to the skin contact sheet according to claim 5, in addition to the fourth feature, printing is performed only on the convex surface of the surface uneven pattern layer, which is the convex surface of the concave-convex structure, to obtain a smooth-slip printed surface.
A skin contact sheet having a predetermined first surface and a second surface can be obtained only by performing good slippery printing only on the convex surface of the uneven structure on the upper surface of the elastic sheet body.

Further, according to the skin contact sheet according to claim 6, in addition to the action and effect according to the configuration according to any one of claims 1 to 5, the first surface is configured as a linear pattern (including dots). In addition, the line width W is in the range of 1.0 to 6.0 mm, and the distance L between adjacent lines in the direction perpendicular to the direction in which the human body parts such as the sole and palm move forward and backward is in the range of 2 to 20 mm. The ratio W / L of the line width W and the distance L between adjacent lines is in the range of 1/2 to 1/2, and the step D between the first surface and the second surface is in the range of 0.1 to 3.0 mm. Because it is
By increasing the line width W of the linear pattern constituting the first surface from 1.0 mm to 6.0 mm, it is possible to adjust it so that the foot or the like is more slippery and easier to insert. it can. On the contrary, by narrowing the line width W, the slippery portion can be reduced and the line width W can be adjusted in a direction that facilitates immobilization.
Further, by increasing the line-to-line distance L from 2 mm to 20 mm, it is possible to adjust the foot or the like in a direction in which it is easier to contact the second surface and immobilization is easy. On the contrary, by reducing the line-to-line distance L, it is possible to adjust in a direction in which the foot or the like is less likely to come into contact with the second surface and is easily inserted.
Further, by increasing the ratio W / L of the line width W and the line-to-line distance L from 1/20 to 1/1, the relative ratio of the width and area of the first surface to the second surface is increased. It can be adjusted so that the foot or the like is more slippery and easier to insert. On the contrary, by reducing the ratio W / L, it is possible to adjust the foot or the like in a direction in which it is easier to come into contact with the second surface and immobilization is easier.
Further, by increasing the step D between the first surface and the second surface from 0.1 mm to 3.0 mm, it is possible to gradually make it difficult for the foot or the like to come into contact with the second surface, and the insertion can be performed. It can be adjusted in an easy direction. On the contrary, by reducing the step D, it is possible to adjust the step D so that the foot or the like can more easily come into contact with the second surface and the immobilization can be easily performed.
Then, the line width W, the line-to-line distance L, the ratio W / L, and the step D of the linear pattern are within the above ranges according to the good slipperiness and the non-slipperiness of the first surface and the second surface. By setting with, it is possible to achieve good insertion and good immobilization after mounting.

It can be inserted smoothly without making it difficult to insert the foot into the sock. Moreover, once the insertion of the foot is completed and the weight is applied vertically from the sole of the foot, the sole of the foot can be immobilized so as to be in perfect contact with the second surface of the skin contact sheet on the inner sole of the sock. .. Therefore, it is possible to provide socks that can sufficiently reduce the friction with the sole of the foot and sufficiently prevent the occurrence of inflammation and the occurrence of beans due to exercise and the like.

It is a figure which shows the relationship between a foot and a sheet in a state which is placed on the skin contact sheet which concerns on 2nd Embodiment of this invention, and has added its own weight.

First, the configuration of the skin contact sheet 10 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.
The skin contact sheet 10 is composed of two types of surfaces, a first surface 10a and a second surface 10b, for contact surfaces that come into contact with human body parts such as the soles of the feet.
The first surface 10a is configured as the outermost surface of the contact surface with a human body portion such as the sole of the foot. Further, the first surface 10a is configured as a good slippery surface so that the human body portion can slip on the first surface 10a.
The second surface 10b is configured at a lower position with a small step D with respect to the first surface 10a. Further, the second surface is formed as a non-slip surface so that the human body portion does not easily slip on it.

The skin contact sheet 10 is configured as a breathable elastic body as a whole. Further, in the skin contact sheet 10, when a vertical pressure is applied from a human body portion in contact with the skin contact sheet, the first surface 10a of the skin contact sheet 10 becomes a second surface due to the cushioning property possessed by the elastic body. It is configured to sink relative to 10b. Then, when a certain amount of vertical pressure is applied, the second surface 10b also comes into contact with the human body portion, and the contacting human body portion is configured to be immobile on the non-slip second surface 10b. ing.

The skin contact sheet 10 includes at least a non-slip elastic sheet main body 11 made of a continuous cell type foamed resin and a surface uneven pattern layer 12 formed on the upper surface of the elastic sheet main body 11.
The upper surface of the surface uneven pattern layer 12 is the first surface 10a. Further, the upper surface of the elastic sheet main body 11 on which the surface uneven pattern layer 12 is not laminated is the second surface 10b.
The elastic sheet body 11 has a cushioning property as an elastic body, and when a pressure in a vertical direction is applied to the first surface 10a, the first surface 10a sinks relative to the second surface 10b. ..

The surface uneven pattern layer 12 can be configured as a print layer PL laminated on the upper surface of the elastic sheet main body 11. By constructing the print layer PL with a printing material having good slipperiness, the first surface 10a, which is the upper surface of the print layer PL, can be formed with good slipperiness. Of course, the printing material itself does not need to have good slipperiness as long as the upper surface of the print layer PL has good slipperiness. By making the upper surface of the print layer PL smooth, the first surface 10a becomes smooth, and the foot or the like can easily slide on the first surface 10a. Therefore, the insertion of hands and feet becomes easy.
Good slipperiness and non-slipperiness can be objectively judged by the coefficient of friction. The closer the friction coefficient is to 0, the better the slipperiness, and the closer the friction coefficient is to 1, the less slippery it is.
When the surface uneven pattern layer 12 is composed of the print layer PL, it is preferable that the print layer PL also has air permeability. For example, by dispersing fine ventilation holes in the print layer PL, it is possible to secure air permeability in the surface uneven pattern layer 12.
It is possible to make the print layer PL smooth and to give the print layer PL breathability by using a known technique and a well-known technique.

As described above, the elastic sheet body 11 is made of a non-slip open-cell foamed resin.
Here, the category of open-cell foamed resin includes open-cell foamed rubber. Therefore, the elastic sheet body 11 is specifically made of an elastomer of a non-slip open-cell foam resin or a non-slip open-cell foam rubber.
The production or production of foamed resin or foamed rubber in an open cell type can be performed using known and well-known techniques.
The elastic sheet main body 11 can be made non-slip by making the resin elastomer or foam rubber material itself that constitutes the elastic sheet main body 11 a material that tends to be non-slip. In addition to the selection of the material itself, the surface itself of the elastic sheet body 11 can be made non-slip by subjecting it to physical and chemical surface treatment such as adjusting the surface roughness. As a surface treatment, the surface has good adhesion to the skin of human soles and palms, and also has adsorptivity to the skin or, if necessary, adhesiveness, resulting in a friction coefficient of 1 on the surface. This can be achieved by chemically and physically adjusting the surface texture in the direction closer to that.
The smoothness of the first surface 10a can be achieved by forming the print layer PL constituting the first surface 10a with a material having good slipperiness. In addition, by adjusting the physical and chemical properties of the upper surface of the print layer PL so that it is slippery to the skin of the human body that comes into contact with it, such as the soles and palms of human feet, that is, the coefficient of friction is close to zero. Can be achieved.

The elastic sheet main body 11 having elasticity, slip resistance, open cell type and the like can be more preferably obtained by using, for example, a flexible polyurethane foam as a material. Also, soft acrylic foam can be slightly inferior in strength. Further, other resin elastomer-based or rubber-based open-cell sponges can also be adopted. However, regardless of whether the material is a flexible polyurethane foam or a soft acrylic foam, a more preferable elastic state and non-slip state can be obtained by adjusting the compounding conditions such as the raw material ratio and the foaming agent ratio and the manufacturing conditions. It is necessary to obtain a bubble state.
On the other hand, the smooth-slip print layer PL used for the surface uneven pattern layer 12 is made by using a smooth-slip water-based or oil-based ink containing various dyes, pigments, and other materials as main components. It is possible to obtain more preferably. In addition, by adopting printing conditions incorporating printing specifications that make the surface smooth, it is possible to obtain a more preferable smooth surface. As the pigment ink serving as the printing layer PL, for example, an ink containing acrylic acid ester as a main component can be used.

As shown in FIGS. 1 and 2, the surface uneven pattern layer 12 can be configured such that the planar shape of the convex pattern composed of the print layer PL becomes a continuum of the hexagonal pattern. In this case, the hexagon with a hexagonal pattern is preferably a long hexagon extending in the direction in which the foot or hand rubs (left-right direction in FIGS. 1 and 2) rather than a regular hexagon. That is, of the six sides of the hexagon, the dimensions of the two parallel sides that match the direction ARD (see FIG. 3, FIG. 1 and FIG. 2 in the left-right direction) in which the human body part advances and retreats are long, and the angle with respect to the advancing and retreating direction ARD. It is preferable to use a long hexagon in which the dimensions of the remaining four sides are shortened.
By adopting such a long hexagon, it is possible to reduce the resistance to the human body part sliding on the long hexagon, and improve the good slipperiness of the first surface 10a from the pattern surface of the surface uneven pattern layer 12. Can be made to.

The surface uneven pattern layer 12 can have a rhombic pattern continuous body instead of the convex pattern planar shape formed of the print layer PL as a continuous body of the turtle shell pattern. Also in this case, the rhombus having a rhombus pattern is preferably a long rhombus extending in the direction in which the human body portion advances and retreats (left-right direction in FIGS. 1 and 2), as in the case of the long hexagon.
Of course, the planar shape of the convex pattern made of the print layer PL is not necessarily limited to the hexagonal pattern and the rhombus pattern described above, and may form other patterns.

The function of the skin contact sheet 10 will be described with reference to FIGS. 3 and 4.
First, referring to FIG. 3, in a state where the vertical pressure VDP is hardly applied to the skin contact sheet 10, the foot F, which is a human body part, is in the advancing / retreating direction ARD along the upper surface of the skin contact sheet 10. The case of trying to move will be described.
In this case, the sole of the foot comes into contact with the first surface 10a of the skin contact sheet 10, but does not come into contact with the second surface because the vertical pressure VDP is not applied to the skin contact sheet 10. Therefore, the foot F can easily move in the advancing / retreating direction ARD direction while being in contact with the smooth first surface 10a.
This situation will be described later, but when the foot F is inserted into the sock provided with the skin contact sheet 10, the hand is inserted into the glove provided with the skin contact sheet 10, and the skin contact sheet 10 is provided. When the foot F is inserted into a shoe with an insole, it corresponds to the case where the foot F is inserted into a shoe directly provided with the skin contact sheet 10.

Next, referring to FIG. 4, the movement to the advancing / retreating direction ARD due to the insertion of the foot F or the like is now completed, and a certain vertical pressure VDP from the foot F, which is a body part, is applied to the skin contact sheet 10. The case will be described.
In this case, the sole of the foot pushes down the first surface 10a in contact with the second surface 10b relative to the second surface 10b to cause the sole to sink. Therefore, the sole of the foot comes into contact with the second surface 10b and is immobilized by the non-slip second surface 10b. That is, the foot F is prevented from moving back and forth and left and right on the upper surface of the skin contact sheet 10. As a result, friction on the sole of the foot is eliminated, and it is possible to eliminate the generation of frictional heat, the generation of inflammation, and the generation of beans and blisters.
This situation will be described later, but when exercising while wearing shoes with the skin contact sheet 10 or when holding an object while wearing gloves with the skin contact sheet 10. It corresponds to the case of exercising by wearing shoes with an insole provided with the skin contact sheet 10 or shoes directly provided with the skin contact sheet 10 with bare feet or the like.

The skin contact sheet 10 can be made of, for example, a strip-shaped sheet as a continuous body or a batch sheet having a constant length and width. Then, the skin contact sheet 10 can be processed into a sole-shaped skin contact sheet 101 as shown by the alternate long and short dash line in FIG. 1 by, for example, punching, cutting, or other methods.
The sole-shaped skin contact sheet 101 becomes a part of the sock by being integrally attached to the inner sole of the sock (not shown). The sole-shaped skin contact sheet 101 is also the skin contact sheet of the present invention.
Further, the sole-shaped skin contact sheet 101 becomes a part of the insole by integrally attaching it to the upper surface of the insole of the shoe. Of course, by appropriately increasing the thickness of the elastic sheet body 11 of the skin contact sheet 10, the sole-shaped skin contact sheet 101 itself can be used as an insole.
Further, the sole-shaped skin contact sheet 101 becomes the inner sole of the shoe or a part thereof by integrally attaching it to the upper surface of the inner sole of the shoe.
Similarly, by obtaining a palm-shaped contact sheet (not shown) from the skin contact sheet 10, and integrally attaching the palm-shaped contact sheet to the inner surface of the palm side of the glove, it becomes a part of the glove. This palm-shaped contact sheet is also the skin contact sheet of the present invention.

The skin contact sheet 10 does not necessarily have to be a flat sheet, including the sole-shaped skin contact sheet 101 and the palm-shaped contact sheet. It is assumed that the upper surface provided with the first surface 10a and the second surface 10b is a curved surface and is three-dimensionally formed. Such a three-dimensionally curved skin contact sheet 10 functions as a skin contact sheet that extends from the sole (palm) to the side of the foot (side of the hand), and in some cases, the instep (back of the hand). It becomes possible to respond to the need to exert it.

The configuration of the skin contact sheet 10 according to the second embodiment of the present invention will be described with reference to FIGS. 5 and 6. In the present embodiment, the surface uneven pattern layer 12 formed on the upper surface of the elastic sheet main body 11 is configured by forming the upper surface itself of the elastic sheet main body 11 into an uneven structure.
As a method of forming the surface uneven pattern layer 12 with the uneven structure of the elastic sheet main body 11, for example, there is a method by embossing. Then, by surface-treating the convex surface of the uneven structure which is the surface uneven pattern layer 12, the first surface 10a of the skin contact sheet 10 can be obtained. Further, by making the concave surface of the concave-convex structure of the elastic sheet main body 11 a non-slip surface, the second surface 10b can be obtained.
In the above case, the non-slip elastic sheet main body 11 is used, the concave surface of the concave-convex structure is directly treated as the second surface 10a with the surface of the non-slip elastic sheet main body 11, and only the convex surface of the concave-convex structure is surface-treated with good slipperiness. The second surface 10b can be obtained.

As a method of forming the upper surface itself of the non-slip elastic sheet main body 11 into the concave-convex structure to form the surface concave-convex pattern layer 12, and making only the convex surface of the concave-convex structure smooth to form the first surface 10a, the convex surface of the uneven structure. There is a method of applying a thin print P to the surface of the above. That is, the first surface 10a composed of the smooth-slip printing surface can be obtained by printing only the convex surface using the good-slip printing material.

As a method of forming the upper surface itself of the non-slip elastic sheet main body 11 into the uneven structure to form the surface uneven pattern layer 12, and making only the convex surface of the uneven structure smooth to form the first surface 10a, printing on the convex surface P Other surface treatments may be applied to obtain a smooth smooth surface without applying the above. For example, it is possible to physically or chemically reduce the surface roughness to make it smooth.

In the skin contact sheet 10, the good-slip first surface 10a and the non-slip second surface 10b are uniformly dispersed and arranged on the entire surface of the skin contact sheet 10 so that the human body portion is smooth at the time of insertion. It is preferable in terms of the functions of the skin contact sheet 10 such as smooth sliding and movement and reliable immobilization of the human body part after the insertion is completed.
Further, in the skin contact sheet 10, the area ratio of the first surface 10a and the second surface 10b as a whole is higher on the second surface 10b from the viewpoint of emphasizing immobilization after the insertion of the human body portion. Configure to be large. The first surface 10a is for improving the ease of putting on and taking off the human body portion at the time of insertion and removal.
Further, in the skin contact sheet 10, considering the smooth insertion of the human body portion and the like, the shape of each unit constituting the first surface 10a (for example, each hexagon of the hexagonal pattern corresponds to each hexagon) is the advancing / retreating direction ARD of the human body portion. The shape extending to is preferable. Further, it can be said that the width of each unit constituting the first surface 10a (for example, the width of each hexagonal outer diameter line of the hexagonal pattern) is preferably narrow in the direction perpendicular to the advancing / retreating direction ARD. Further, the area of each unit constituting the first surface 10a (for example, the area of the outer diameter line of each hexagon of the turtle pattern) is the area of each unit constituting the second surface 10b (for example, the area of each hexagon of the turtle pattern). It is preferable that the area is smaller than the area surrounded by the outer diameter line).

Considering the ideal conditions of the first surface 10a and the second surface 10b of the skin contact sheet 10 as described above, the surface uneven pattern layer 12 of the skin contact sheet 10 of the present invention linearly forms the first surface 10a. It is preferably configured as a pattern.
Here, the linear pattern is a concept in which the elements constituting the pattern include points in addition to lines.
In the case of a linear pattern, not all lines need to be continuously connected on the entire surface. It shall include those in which a part of the line is divided in the middle.
In the case of the hexagonal pattern shown in FIGS. 1 and 2, the entire surface is uniformly composed of continuous lines except for the end portion of the skin contact sheet 10. The hexagonal pattern that constitutes the surface uneven pattern layer 12 has a continuous hexagonal outer line formed of convex lines to form a first surface 10a, and the inside surrounded by the convex outer line is formed of a concave surface. 2 The surface is 10b.

In order to exert the function of the skin contact sheet 10 of the present invention more effectively, it is necessary to further consider the line width W, the line distance L, the step D, and other conditions of the linear pattern. The point is to ensure that the foot and hands are inserted smoothly, while ensuring that the sole and palm do not rub against the contact surface after insertion, immobilize, and cause inflammation and legumes on the sole and palm. It is to clarify more effective conditions to surely prevent the formation of inflammation.

The line width W of the linear pattern constituting the surface uneven pattern layer 12 is in the range of 1.0 to 6.0 mm. If the line width W is less than 1.0 mm, it is too thin for the sole or palm to come into contact with the line and slide well. Further, the sole or palm protruding from the line easily comes into contact with the concave surface (second surface 10b), further movement is prevented, and the foot or hand cannot be smoothly inserted. On the other hand, when the line width W exceeds 6.0 mm, the line becomes too thick and it becomes easy to insert the foot or palm, but the thickened line (first surface 10a) becomes difficult to sink and protrudes from the line. It becomes difficult for the sole and palm of the foot to come into contact with the concave surface (second surface 10b). For this reason, the soles and palms cannot be sufficiently immobilized.
The line width W is more preferably 1.5 to 5.0 mm, still more preferably 2.0 to 4.0 mm, in consideration of slipperiness at the time of inserting the sole or palm and immobilization after the insertion is completed.

The linear pattern constituting the surface uneven pattern layer 12 has an adjacent line distance L of 2 to 20 mm in a direction perpendicular to the direction in which the human body portion such as the sole or palm moves forward and backward (the direction in which the human body portion is inserted). The range of. If the distance L between adjacent lines is less than 2 mm, the distance L between adjacent lines is too narrow, and even if the line width W of the linear pattern is reduced to 1.0 mm, the human body part of the sole or palm is between the adjacent lines. It becomes difficult to contact the concave surface (second surface 10b). For this reason, it becomes difficult to achieve immobilization after the insertion of the sole and palm is completed. On the other hand, when the distance L between adjacent lines exceeds 20 mm, the distance L between adjacent lines becomes too wide, and even if the line width W of the linear pattern is increased to 6.0 mm, the sole of the foot protruding from the line The human body part such as the palm easily comes into contact with the concave surface (second surface 10b) between the adjacent lines, which makes it difficult to smoothly insert the foot or hand.
The distance L between adjacent lines in the direction perpendicular to the direction in which the human body part moves forward and backward is more preferably 3.0 to 15.0 mm in consideration of slipperiness at the time of inserting the sole or palm and immobilization after the insertion is completed. 4.0 to 10.0 mm is more preferable.

The ratio W / L of the line width W of the linear pattern constituting the surface uneven pattern layer 12 and the distance L between adjacent lines is set in the range of 1/20 to 1/1.
As this ratio W / L becomes smaller, the sole and palm of the foot are more likely to come into contact with the second surface 10b, and it becomes more difficult to insert the foot and hand. However, on the other hand, the immobilization of the sole and palm after insertion becomes stronger. When the ratio W / L is less than 1/20, the sole or palm of the foot immediately contacts the second surface 10b when inserting the foot or hand, making further insertion very difficult. When the ratio W / L exceeds 1/1, the insertion is easy, but after the insertion is completed, it becomes difficult for the sole and palm to sufficiently contact the second surface 10b, and immobilization tends to be insufficient. ..
The ratio W / L of the line width W of the linear pattern to the distance L between adjacent lines is 1/10 to 1/2 in consideration of slipperiness when inserting the sole or palm and immobilization after the insertion is completed. Is more preferable, and 1/5 to 1/2 is even more preferable.

The step D between the first surface 10a and the second surface 10b constituting the surface uneven pattern layer 12 is 0.1 to 3.0 mm. This step D prevents the sole and palm from coming into contact with the non-slip second surface 10b when inserting the foot F or the hand, and after the insertion is completed, the step D is added to the skin contact sheet 10 above a certain level. It is a step formed so that the sole and palm sink together with the first surface 10a and come into contact with the second surface 10b due to the vertical pressure VDP.
When the step D is less than 1.0 mm, the sole and palm of the foot immediately come into contact with the slippery second surface 10b at the time of insertion, which makes insertion difficult. If the step D exceeds 3.0 mm, the step is too large, and even if vertical pressure VDP is applied to the sole or palm after the insertion is completed, the sole or palm may easily come into contact with the second surface 10b. You can't do it, and you can't immobilize it well.

Of course, how much the step D is set depends greatly on the cushioning property of the elastic sheet body 11 as an elastic body. When the elastic sheet body 11 has a large cushioning property, the first surface 10a sinks significantly even with the same vertical pressure VDP. Further, when the cushioning property of the elastic sheet body 11 is small, the degree of sinking of the first surface 10a becomes small with respect to the same vertical pressure VDP.
Therefore, it goes without saying that not only the set value of the step D but also the set values of the line width W of the linear pattern, the distance L between adjacent lines, and the ratio W / L are influenced by the cushioning value of the elastic sheet body 11. No.
However, the above-mentioned numerical ranges of the line width W, the distance between adjacent lines L, the ratio W / L, and the step D are considered to be appropriate ranges for the commonly used foamed sponge rubber and foamed sponge resin elastomer. Is being considered. That is, the line width W, the distance L between adjacent lines, the ratio W / L, and the step D are, for example, an elastic sheet having a hardness of about 20 to 60 for a sponge altimeter (JISE type) of the foamed sponge rubber or foamed sponge resin elastomer. It can be said that it is a numerical range that applies when is used.
