JPH1014606A - Shoe socking for slipper and the like - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a shoe socking from slipping out easily even if stepping pressure is applied by making a part fitting to a foot cover of a shoe socking made of a corrugated board wide in width and inserting this part into a foot wear and stepping it on both bides of the foot cover. SOLUTION: In such footwears 10 as slippers and slipping-on sandals with no peripheral wall on their back parts, the front half of a foot placing face 12 is surrounded with a foot cover 14. A shoe socking 16 is mounted by placing it on the foot placing face 12 and is made of a corrugated board. In this shoe socking 16, the width (a) of the part 18 fitted to the foot cover is made wider than the width (b) of the foot cover 14 of the footwear 10 (a>b). When such the shoe socking 16 as this is pushed into the foot cover 14 along the foot placing face 12 of the footwear 10, the part 18 fitted to the foot cover is pinched by both sides of foot cover 14 and the both sides are raised up to exhibit such degree of hooking force that does not make it slip out of the position even when an outer force is applied to some extent. Therefore, even if it is used under this condition, there exists no possibility of slipping out of the shoe socking 16 and no problem in practical use.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insole such as slippers and slippers to be attached to footwear having a peripheral portion at a rear portion and a foot covering at a front portion, such as a slipper and a hook-and-loop sandal.

[0002]

2. Description of the Related Art The present inventor has previously proposed a cardboard insole made of cardboard (utility model registration No. 1903067).
Since the insole uses inexpensive cardboard, it can be disposably used, and the steps are suitable for stimulating the sole of the foot and comfortable. In this regard,
The same applies to footwear such as slippers and sandals. In particular, since such footwear is often used in a state where it is left alone in a place where many people gather, it tends to become dirty and conspicuous. Therefore, it is significant to use disposable insoles.

[0003]

However, since these footwear do not have a peripheral wall at the heel (rear) portion, if the insole is simply placed on the footrest surface of the footwear, it will come off due to treading pressure or the like. For this reason, the present inventor has previously proposed a case in which the back surface of the insole is lightly adhered to footwear using an adhesive or a pressure-sensitive adhesive (Japanese Patent Application No. 7-212829). However, when these adhesives and pressure-sensitive adhesives are used, they remain on the trace when the insole is peeled off, and cause discomfort to the sole of the foot when worn without the insole. The present invention has been made to solve such a problem, and an object of the present invention is to provide an insole which can be locked even with footwear having no peripheral wall at a rear portion and which leaves no trace even when peeled off.

[0004]

SUMMARY OF THE INVENTION Under the above-mentioned problems, the present invention relates to a cardboard cardboard which is attached to a footrest surface of footwear which has no peripheral wall at the rear and has a foot covering at the front, such as slippers and sandals. The width of the part of the insole that comes to the foot covering of this insole is wider than the width of the foot covering of the footwear, and the insole is pinched on both sides of the foot covering at the time of wearing, so that the position of the insole is hard to shift An insole, such as slippers, is provided.

Further, according to the present invention, there is provided a temporary fixing material on the back surface of a heel portion of a foot resting surface of an insole, which adheres to the foot resting surface but does not leave glue or the like on the other party when peeled off. And an insole such as a slipper that employs a seal piece of ink for a suction cup as the temporary fixing material.

By taking the above measures, the present invention firstly widens the portion of the insole which comes to the foot covering, so that the portion which comes to the foot covering is sandwiched on both sides of the foot covering. In other words, even if tread pressure is applied, the position cannot be easily shifted. And since it can be mounted only by inserting the insole into the foot covering, the operation is also easy. Furthermore, by attaching a temporary fixing material that adsorbs to the other side but does not leave glue etc. on the back of the heel part, prevention of misalignment becomes more reliable, and no trace remains even after peeling, Does not impair.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of an insole showing an example of the present invention, FIG. 2 is a plan view of a slipper, and FIG. 3 is a cross-sectional view of the slipper with the insole mounted thereon. In such a footwear 10, a front half of a foot rest surface 12 is surrounded by a foot cover 14. The insole 16 according to the present invention is mounted on the footrest surface 12 and mounted thereon, and is made of cardboard.

In the insole 16, the width a of the portion 18 coming to the foot covering is larger than the width b of the foot covering 14 of the footwear 10 (a> b). When such an insole 16 is pushed into the foot covering 14 along the foot placing surface 12 of the footwear 10, the portions 18 coming to the foot covering on both sides of the foot covering 14 are pinched, and both ends are raised (FIG. 3). (See Reference) Even if a small external force acts, the locking force is such that the position does not shift.

Accordingly, even if the insole 16 is used in this state, the insole 16 does not come off while walking, and there is no problem in practical use. Is suitable. That is, except for the portion 18 that comes to the foot covering, for example, on the back surface of the heel portion 20, the suction force is exerted on the foot resting surface 12, but when the film is peeled off, there is no temporary adhesive left on the other party. The material 22 is stuck.

There are various types of the temporary fixing member 22, but the point is that no glue such as an adhesive or an adhesive is used. The most suitable temporary fixing material 22 is suction ink manufactured by Teikoku Ink. This ink for sucker is obtained by printing the sucker ink in a closed pattern that can maintain the sucker performance by screen printing (there are various patterns).

FIG. 8 is a plan view of the suction ink seal, and FIG. 4 is a rear view of the insole 16 to which the suction ink seal piece is attached. The suction ink is provided in a sealed state. Therefore, what is cut into an appropriate size may be used as the temporary fixing member 22, which may be attached to the back of the heel portion 20 of the insole 16 or the like.

The suction effect of the suction ink is not due to the action of an adhesive such as glue, but to the physical suction action. Therefore, the sucker function is not exerted unless it is pressed against the other party with a certain strength. However, when used for the insole 16, the weight is applied from above, so there is no problem in this respect. If the other party has air permeability, the sucker action is insufficient, so that the footwear 10 used here is preferably made of leather or vinyl, and not of cloth.

By the way, the size (length) of the insole 16 is
Even if the size of the footwear 10 is slightly different, use of the footwear 10 does not hinder the use, but it is certain that the size of the footwear 10 should be the same. FIG. 7 is a plan view of the insole 16 showing this, but several types of perforations 24 that can be set to an appropriate length may be provided on the heel portion 20 and the like.

When the insole 16 using the temporary fixing agent 22 becomes old with use, it is peeled off and replaced with a new one. Also in this case, it can be easily removed by pulling it by hand (the part 18 coming to the foot covering). Thus, footwear 1 with this removed
Since there is no trace of glue or the like on 0, use without the insole 16 does not cause any discomfort. The temporary fixing agent 22 is placed in a distribution process or the like in an exposed state, but also in this case, it does not stick to each other.

The insole 16 is made of cardboard. FIG. 9 is a cross-sectional view of a single-sided cardboard. The single-sided cardboard has a structure in which a middle core (step) 28 is adhered to a liner 26.
Step 28 has only one side. On the other hand, the two-sided corrugated cardboard in which the liners 26 are stuck back to back and the steps 28 are provided on both sides is called.

The cardboard used in the present invention may be either one-sided or two-sided, but one-sided cardboard is preferable because the flat liner 26 can be attached to the footwear 10 of the other party. The running direction of the step 28 is vertical,
It may be horizontal or oblique. FIG. 5 is a plan view of the insole 16 using single-sided cardboard.

FIG. 10 is a cross-sectional view of a single-sided corrugated cardboard cut along a line parallel to the step 28. A crush line 30 for crushing the step 28 so as to intersect with the step 28 may be inserted. The crushing line 30 can be easily formed by a roll or the like, and the insertion of the crushing line 30 has the effect of increasing the strength of the step 28 and improving the wearing comfort. FIG. 6 is a plan view of the insole 16 using a single-sided cardboard with a crush line.

[0018]

As described above, according to the present invention, first of all, the part of the insole made of cardboard which comes to the foot covering is widened, so that if this part is inserted into the footwear, it will be pinched on both sides of the foot covering. This means that even if tread pressure is applied, it does not come off easily. Therefore, it is possible to manufacture a device which can be easily attached and detached at a low cost. The second is that the temporary fixing material that glue etc. does not remain on the other side is attached to the back of the heel part of the insole,
The misalignment can be more reliably prevented, and no trace remains even after being peeled off, and the feeling of wearing is not impaired.
