Abstract

PROBLEM TO BE SOLVED: To provide socks which uses a sot foamed sheet, which improves air permeability and making the bottom thereof hard to slip without weakening the mechanical strength of the material thereof. SOLUTION: The socks comprises a material laminated with respective air- permeable skins on both sides of a soft foamed sheet into which may small holes are penetrated in the perpendicular direction and is characterized by that small projections for non-slip use are formed on the bottom thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sock using a soft foam sheet, and more particularly to a sock having improved breathability and made the sock sole less slippery.

[0002]

2. Description of the Related Art A flexible foam sheet is a preferable material for cold-protection socks because it has good heat retention and does not allow outside cold to pass through, and is light. In particular, it is preferably used in boots in cold regions, as indoor socks in winter, or as socks for rehabilitation patients in winter. However, when such a material is used, there is a problem that the feet become stuffy, contrary to the improvement of the heat retention, and a plurality of ventilation holes are provided as an improvement.

[0003]

In a sock using a soft foam sheet, a ventilation hole is formed by punching a hole having a diameter of 3 to 5 mm in a state where the soft foam sheet and the skin are laminated. However, there is a problem that the film is broken from the hole during use, and the strength is weakened if the number of holes is increased so as not to cause stuffiness. In addition, the foam material usually covers the surface with a skin to make it easy to attach and detach, but this also causes a pedestrian to easily slip and fall during walking.

[0004]

Means for Solving the Problems The present inventor has studied to solve the above problems and has reached the present invention. The sock according to the present invention is a soft foam having many small holes penetrating in the thickness direction. It is made of a material with breathable skin laminated on both sides of the sheet,
A small protrusion for preventing slippage is formed on the sock sole portion.

[0005] By making a large number of small holes and widely distributing them, the air permeability is greatly improved, and further, the small projections make it difficult for pedestrians to slip and improve safety.

[0006]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a material corresponding to a sock upper in this embodiment. The sock upper part material 1 is a soft foam sheet 3 having a thickness of about 1 to 3 mm, which has many small holes 5 penetrated in the thickness direction, and both sides are covered with a breathable skin 4. It is. The material of the flexible foam sheet 3 is not particularly limited, but is neoprene (registered trademark), polyurethane, vinyl chloride, ethylene-vinyl acetate copolymer, or the like. Although the size of the small holes 5 is not limited, it is usually 0.3 to 1 mm, and the number of the small holes 5 is determined by a balance between the strength of the material 1 and the air permeability. About 5 to 10 pieces per square centimeter are good. The small holes 5 are preferably uniformly distributed over the entire surface of the material 1.

The material of the skin 4 is not particularly limited, but may be nylon, polyester, polyacrylonitrile,
Synthetic fibers such as polyurethane and natural fibers such as acetate and cotton are used. Small hole 5 by covering skin 4
The cover is covered from above and is not visible from the outside, so that the appearance is improved, and the feeling of use of the sock is improved, the strength is improved, and the slip when attaching and detaching is given. In addition, as for the skin 4, one side is the outside of the sock and the other side is the inside of the sock. By using the colored or patterned skin,
The value of the sock 8 can be increased. Further, punching from the top of the skin to form the ventilation holes 6 does not matter at all.

FIG. 2 is a cross-sectional view of a material corresponding to a sock sole. The sock sole material 2 further has a small non-slip projection 7 made of resin on the surface of the material 1.
The small projections 7 are achieved by attaching a lump of resin having a diameter of about 4 to 5 mm on the skin 4. The resin is a resin that can be melted by heat and can be adhered to the skin 4, for example, vinyl chloride, polystyrene, ABS (acrylonitrile-butadiene-styrene), methyl methacrylate,
Examples include polyurethane, nylon, and polyester. The number of the small projections 7 depends on the size thereof, but is practically about 4 to 8 per square centimeter. The small protrusions 7 are preferably distributed uniformly over the entire surface of the sock sole, but the distribution may not be uniform, such as a large portion where a force is applied on the sole and a small portion corresponding to the arch, etc. . Punch from the top of the skin and vent 6
There is no problem creating a.

FIG. 3 is a bottom view of the sock. By arranging the small protrusions 7 on the bottom surface, the small protrusions 7 can prevent slippage.

FIG. 4 shows a sock 8 in this embodiment. The method of manufacturing the sock 8 is not limited at all, but the material 1 corresponding to the sock upper and the material 2 corresponding to the sock sole are separately manufactured, and cut into a necessary mold from both. Can be sewn together to form a sock.

[0011]

The socks according to the present invention have a wide distribution of small holes, and the number thereof can be increased, so that the breathability is greatly improved. , User safety was ensured.
