[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sock having a function of preventing slippage during walking.
[0002]
[Prior art]
When walking while wearing socks, the sock may gradually dislodge due to the mutual sliding that occurs between the shoe and the sock during walking, or you will have to stop and pull up the sock. Sometimes. Socks that have been devised in various ways to prevent such socks from falling during walking have been developed. As socks related to the present invention, Japanese Patent Laid-Open No. 10-251902, Japanese Utility Model Laid-Open No. 60-13906. And Japanese Utility Model Publication No. 6-33906.
[0003]
Socks disclosed in Japanese Patent Application Laid-Open No. 10-251902 are made by changing the tensile force of rubber knitted into socks depending on the part of the foot so that the part of the foot is strong at the thin part and weak at the thick part. Yes, such a configuration enhances the fit to the foot and prevents slippage during walking.
[0004]
The socks disclosed in Japanese Utility Model Laid-Open No. 60-13906 and Japanese Utility Model Laid-Open No. 6-33906 are designed to lock the foot by knitting rubber having a stronger contraction force than the other parts in the ankle part and the mouth part. It increases strength and prevents slipping while walking.
[0005]
[Problems to be solved by the invention]
As shown in FIG. 3A, when walking with the sock 30 attached to the foot F and wearing the shoe 31, the sock 30 receives forces in various directions from the shoe 31 and the foot F. It is considered that the force that causes the maximum slippage is the force P that is received in the state shown in FIG.
[0006]
During the walking motion, as shown in FIG. 3 (b), when one of the left and right feet F tilts forward and tries to kick the ground G, the base portion Ft of the toes tilts the ground G through the shoe sole 31b. Since the heel Fh presses backward and moves in a direction away from the shoe 31, the heel portion 30 h of the sock 30 slides upward along the inner surface of the heel portion 31 h of the shoe 31. The sock 30 receives a force P in the direction of taking off. During walking, the left and right socks 30 receive such a force P intermittently, so that the socks 30 are gradually displaced as the walking time is prolonged.
[0007]
In order to prevent the sock 30 from slipping down due to such a force P, in the socks disclosed in the above-mentioned JP-A-10-251902, JP-A-60-13906, JP-A-6-33906. , The tensile force of rubber knitted into socks is strengthened at the portion where the foot portion is thin, or rubber having a stronger contraction force than the other portion is knitted into the ankle portion and the mouth portion.
[0008]
However, since the force P received by the sock 30 from the inner surface of the heel 31h of the shoe 31 during walking is relatively strong, even the sock disclosed in the above-mentioned gazette cannot be adequately dealt with and gradually walks when walking for a long time. Socks may fall off. In addition, the socks disclosed in the above-mentioned publication have strong force when putting on and taking off socks because rubber with strong shrinkage and tensile force is arranged in the mouth part, ankle part or thin part. This is a burden for the elderly, and if you wear it for a long time, you may feel pressure.
[0009]
The problem to be solved by the present invention is to provide a sock that does not fall down during walking, is easy to attach and detach, and has very little feeling of pressure during wearing.
[0010]
[Means for Solving the Problems]
The sock of the present invention includes a locking part that surrounds the most detail of the ankle when worn, a boundary concave part between the heel and the instep, and a 45-degree downward slope straight line in the walking direction. A lifting portion that surrounds the region closer to the ankle than the closed curve that passes through the contact point with the heel and surrounds the foot is formed of an elastic material having a higher elastic coefficient than the other portion of the sock, and the lifting portion is positioned at the position of the closed curve The lower edge of the part is arranged .
[0011]
When this sock is attached to the foot, the locking part surrounds the vicinity of the most details of the ankle, and the lifting part surrounds the area closer to the toe and closer to the ankle than the closed curve. The lifting portion is fixed to the most detail of the ankle, and the upper edge of the lifting portion is fixed to the locking portion, and is generally extendable along the heel. Therefore, when walking with shoes on, when the force is applied to the sock's buttocks, etc., in the downward direction, the locking part does not move and the lifting part extends in the toe direction, and the downward force is released. If it is done, it will be pulled up by the contraction force of the lifting part and will immediately return to its original state, so there will be no slippage during walking.
[0012]
In addition, since the elastic material having a higher elastic coefficient than the other parts of the socks is laid only in the locking part and the lifting part, it does not hinder the operation of putting on and taking off the socks, and is removable. Is also good. The elastic material that forms the locking portion abuts on the vicinity of the most detailed part of the ankle, and the elastic material that forms the lifting portion abuts on a toe portion or the like having a relatively thick skin, so there is very little pressure feeling during wearing, Comfort is also good.
[0013]
Here, by placing the lower edge of the lifting portion at the position of the closed curve that passes through the contact point between the 45 ° downward straight line and the buttocks and the boundary recess and surrounds the foot in the walking direction, Since the lower edge is positioned above the rear end of the sole, the lower edge of the lifting portion near the heel is caught by the rear end of the sole and cannot be contracted when receiving a force in the downward direction. Can be prevented.
[0014]
In addition, a lateral elastic material having a higher elastic coefficient than other portions of the locking portion is arranged in the closed curve direction in the locking portion, and the lifting portion has other lifting portions in a direction crossing the lateral elastic material. By arranging a vertical elastic material having a higher elastic coefficient than that of the portion, when the sock is worn, the horizontal elastic material enhances the gripping force for the finest details of the ankle, and the vertical elastic material is displaced downward. Since the drag force and the restoring force are improved, the slip-down preventing function is further improved.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a side view showing a state where a sock according to an embodiment of the present invention is attached to a foot, and FIG. 2 is a perspective view showing a state where the sock shown in FIG.
[0016]
As shown in FIG. 1, the sock 1 according to the present embodiment has the same shape as a general sock, and when it is attached to the foot F, the sock 1 is lifted up and down the boundary line 2 so as to surround the vicinity of the ankle. Part 1b is provided. Both the locking portion 1a and the lifting portion 1b are formed of an elastic material having a higher elastic coefficient than the other portions of the sock 1.
[0017]
When the sock 1 is attached to the foot F, the locking portion 1a surrounds the region including the most detail of the ankle, and the lifting portion 1b surrounds the region below it. The lower edge of the lifting portion 1b is a closed curve that surrounds the foot F by passing through the boundary recess F4 between the upper heel F2 and the instep F3 and the contact S between the 45 ° downward slope straight line L and the heel F5 in the walking direction D. Located along C. As a result, the locking portion 1a is fixed in a state where the most detail of the ankle is gripped, and the lifting portion 1b is fixed to the locking portion 1a at the position of the boundary line 2 and is generally attached to the heel F5. It becomes a state that can be stretched along.
[0018]
Therefore, as shown in FIG. 2, when the shoe 3 is worn and the user walks on the ground G, when the force P in the downward direction is applied to the heel portion or the like of the sock 1, the ankle is fixed to the most detail of the ankle. Since the locking portion 1a does not move, the lifting portion 1b located in the vicinity of the heel F5 extends in the direction of the toe F1, but when the force P in the downward direction is released, the elastic material constituting the lifting portion 1b contracts. Since it is pulled up by the force V and immediately returns to its original state, it is possible to prevent the sock 1 from slipping down while walking, and slipping occurs even when walking for a long time or performing work involving walking. There is no.
[0019]
Since the elastic material having a higher elastic coefficient than the other parts of the sock 1 is laid only on the locking part 1a and the lifting part 1b, the operation of putting on and taking off the sock 1 is not hindered. Good detachability similar to socks. The elastic member that constitutes the locking portion 1a abuts on the vicinity of the smallest details of the ankle, and the elastic member that constitutes the lifting portion 1b abuts on the part of the heel F5 where the skin is relatively thick. There are few, and comfortable comfort is obtained.
[0020]
Moreover, in the sock 1, as shown in FIG. 1, the lower edge 1c of the raising portion 1b is arranged along the closed curve C so that the lower edge 1c of the raising portion 1b becomes the rear end portion of the sole of the foot at the heel F5 portion. Since it is positioned above F6, it prevents the lower edge 1c of the lifting portion 1b near the heel from being caught on the rear end F6 of the sole and becoming unable to contract when receiving a force P in the downward direction. can do. In addition, if the lower edge 1c of the raising portion 1b in the heel F5 portion is a region closer to the ankle than the sole rear end F6, it can be provided at a position closer to the sole rear end F6.
[0021]
Further, a lateral elastic material 4 having a higher elastic coefficient than other portions of the locking portion 1a is arranged in the closed curve C direction in the locking portion 1a, and the lifting portion 1b has the lifting portion 1b in a direction crossing the horizontal elastic material 4. Since the longitudinal elastic material 5 having a higher elastic coefficient than the other parts is arranged, when the sock 1 is attached to the foot F, the lateral elastic material 4 exhibits an excellent gripping force with respect to the most detail of the ankle, The contraction force V of the longitudinal elastic member 5 exhibits a resistance force and a restoring force against the force P in the downward direction, which is effective in improving the downward-sloping prevention function.
[0022]
The socks of the present invention are not limited in any way to the material, size, design, etc. of the entire sock, so it is widely used regardless of whether it is a natural material or an artificial material, and whether it is a distinction for men and women of all ages. be able to.
[0023]
【The invention's effect】
