Description

The present invention relates to an anti-slip sock used in sports or daily life.

A conventional general anti-sock sock has a feature that an anti-slip is formed on the installation surface of a normal knit sock with resin or the like, and registered utility model No. 3078614 is a device having the same feature.

Registered utility model No. 3110455, registered utility model No. 3109393, etc. have been proposed as means for forming a slip stopper on the back of the foot together with the ground contact surface.

Japanese Patent Laid-Open No. 2005-29934 is a device for knitting stretchable polyurethane or rubber into a part of a knitted structure of a sock to thereby form a slip stopper.

There is a registered utility model No. 3119464, which is composed of a rubber sheet and stretchable fabric, has a small through hole in the sock, and has been subjected to a non-slip coating process at least on the ground surface.

(1) In the device with anti-slip on the outer surface of the socks sole, the foot is There is a problem of sliding in the socks.
(2) Socks with a non-slip structure on both the inside and outside of the sole, there is a problem in comfortable use because it feels a foreign object on the sole.
(3) In the idea of knitting an elastic material such as rubber into part of the knitting structure of the socks, the force transmitted from the foot is buffered by the knitted part, so it is not suitable for sports applications where instantaneous force is required, However, there is a problem that the knitted structure of convex portions such as the thumb ball and the heel grows and becomes thin and the anti-slip effect is lowered.
(4) In a device composed of a rubber sheet and a stretchable fabric, the rubber sheet is inconvenient for attaching / detaching the socks, and is not suitable for long-time use because heat and stuffiness inside the socks are hardly released.
(5) An object of the present invention is to solve the problems of the prior art and to provide an anti-slip sock useful for a wide range of uses such as daily life and sports.

This is a sock made of stretchy fabric consisting of the sole, buttocks, and upper part, and the peripheries are sewn together. A polyurethane coating film with air permeability is installed on the inner surface of the sole that is in contact with the skin. Further, the outer surface of the sole contact surface is characterized in that an appropriate amount of a thermoplastic elastomer is applied, and a large number of small holes penetrating the sole are formed.

(1) According to claims 1 and 2, the breathable polyurethane coating discharges the steam in the socks to the outside and has appropriate elasticity and viscosity, so that the foot in the socks does not feel uncomfortable on the sole. It is effective as a means to prevent slippage. On the other hand, the frictional force generated between the application surface of the thermoplastic elastomer and the floor or shoes becomes an effective anti-slip. By this double-sided effect, the sock can efficiently transmit the force to the shoe or the ground surface without losing the force of the foot due to slipping.
(2) Since the anti-slip effect can be changed by adjusting the viscosity, application amount, or application shape of the thermoplastic elastomer, it is possible to provide an anti-slip sock suitable for the purpose of use by a simple technique.
(3) Since the sole part, the upper part, and the heel part are all stretchable, the socks can be easily attached and detached, and the non-slip socks can be provided in a wide range by using the stretchable fabric suitable for each application.

According to the third aspect, the through hole is expanded by the force received from the convex portion such as the thumb ball and the heel, and the stretching force of the part fabric is dispersed. As a result, the part fabric is prevented from being stretched and thinned, and the anti-slip effect is maintained. In addition, the compression of the convex fabric can be dispersed to fit the entire foot, and a comfortable non-slip sock can be provided with a ventilation heat dissipation effect from the through hole.

According to the fourth aspect, since it is possible to meet the specifications stipulated in the sports competition rules, the use in sports is widened, and it is possible to provide an anti-slip sock suitable for cold protection purposes or wearing boots in daily life.

Hereinafter, the present invention will be described with reference to the drawings illustrating embodiments of the present invention.

FIG. 1 is an overall side view when the socks are mounted, and FIG. 3 is a plan development view of a state in which a sole portion 1, an instep portion 2 and a heel portion 3 constituting the sock body are cut in three dimensions. However, only the sole part 1 shows both surfaces of the porous polyurethane coating 9 surface of the foot back surface 10 and the thermoplastic elastomer 4 coating surface of the ground contact surface 14. The elastic fabric used for the sole 1 is an elastic tricot knitted fabric 7 having a composition of 91% polyester and 9% polyurethane, and an elastic jersey having a composition of 80% polyester and 20% polyurethane in the upper part 2 and the heel part 3. Knitted fabric 8 is used.

As shown in FIGS. 1 to 3, the sole 1 is coated with a porous polyurethane coating 9 having air permeability on the sole 10 of the stretchable tricot knitted fabric 7 over the entire sole 1 with a thickness of 0.5 mm. An appropriate amount of a long granular thermoplastic elastomer 4 having a thickness of 0.2 to 0.5 mm is applied to the entire area of the sole 1 on the stretchable tricot knitted fabric 7 of the ground contact surface 14. With the form in which the entire area of the sole 1 has a three-layer structure, it is possible to simultaneously prevent slipping of the foot in the sock and slipping of the sock body and the grounding surface 14. The through hole 5 having a diameter of 2 mm is installed in the entire area of the sole 1, and particularly when the socks are used with sports shoes, the through hole 5 promotes ventilation and heat dissipation, and is an effective means for maintaining a comfortable feeling of use. Become.

As shown in FIG. 2, the penetrating small holes 5 expand at the convex portions of the thumb ball 11 and the heel 12, and disperse the stretching force that is locally strongly applied. In the conventional socks, the knitting structure is thin due to the strong thumb ball 11 and the heel 12, but this defect is improved by the through small holes 5, and the anti-slip effect of the thermoplastic elastomer 4 is improved. It is effective in keeping at. As shown in FIG. 1, due to the effect of the thermoplastic elastomer 4 applied up to the heel 12, it is effective as a mode for reducing as much as possible the force lost due to slipping when transmitting force in sports.

As shown in FIGS. 1 and 2, the three-dimensionally cut portions are stitched flat so that the polyester yarn 6 does not hit the ground surface 14 or the heel 12. Thus, when the sock is worn, the polyester yarn 6 is a form that suppresses an unpleasant wearing feeling and a foreign object feeling.

FIG. 4 shows a knee-length stocking with a tubular knit hose 13 attached to the sock body, which can be adapted to a form conforming to the sports competition rules and is suitable for wearing a cold protection purpose or boots.
