Abstract

<P>PROBLEM TO BE SOLVED: To provide a structure in which a shoe is normally easy to put on while, if necessary, it is closely fitted to the foot with a band or the like so that the falling-off is eliminated. <P>SOLUTION: The two ends of a U-shaped strap are each rotatably connected to a proper position from the rear of the shoe body. A hole of the strap suitably situated slightly backward from the connected position is linked to a pull strap. When the pull strap is pulled forward, the U-shaped strap linked thereto is raised from the rear, with the connected part with the body as a pivot. The rear part of the U-shaped strap thereby reaches around the Achiles tendon above the heel and holds the heel part. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

Shoes and sandals.

In sandals, there is a bag-like or band-like foot insertion part at the front of the foot, in other words, there is only a hooking part, and there is a foot or other fixed object at the back of the buttocks. There are two ways
For shoes, there is a common point that all types have a heel part, but there is a type that does not have a strap to fix, there are types that fix with velcro instead of a strap, the height of the shoe, There are various things such as height, field of use, shape difference depending on field of use.

The advantage of sandals is that they can be removed immediately.
It is useful when you are in a hurry or when you are in the vicinity.
On the other hand, when walking to a place with a little distance, or when rushing to a short run, the sandals are not completely fixed to the feet, so it is unstable and it is also difficult to make a sound.
On the other hand, as opposed to sandals, shoes are good for long walks, but not for when you are in a hurry to go to a little place.
Even when used for long-distance walks such as commuting to school, wearing shoes was too time-consuming and inconvenient.
Or if you have to tie your shoelaces to a certain fixed position, positioning is quite difficult if you are tying them with laces.
In addition, in an aging society, the number of people with reduced physical functions and those who need nursing care are increasing. It is.

Sandals should be structured so that they can be worn quickly, but can be easily and quickly attached to the foot with a band, etc. so that it does not come off the foot when necessary.
In addition, shoes must be structured so that they can be put on and taken off easily and quickly.
Also, if possible, make it possible to attach and detach automatically.
In all cases, make shoes with a safe and durable structure.

BEST MODE FOR CARRYING OUT THE INVENTION

B in Fig. 1 is a normal sandal. In other words, it is footwear that has a rubber sole with a thickness of 1 to 2 cm, and a band or bag that puts the foot on the front half. (In Fig. 1 and other figures, the front part has almost the same shape as the shoe.)
After that, the U-shaped frame (u1) that is slightly larger than the U-shaped frame (u1) is formed from the heel part in a shape that matches the U-shaped outer shape (Bu) of the shoe sole from the position of the heel to the middle. Arranged in an inverted U shape.
The material should be strong enough not to be deformed or damaged even when stepped on with a hard material such as metal or plastic.

The U-shaped frame (u1) is screwed to the spacer (B3) screwed into the frame connection position on the rubber bottom with holes (u2) drilled at both ends, and the rear (u3) of the U-shaped frame is a circle It is designed to move when activated, and the U-shaped rear part (u3) holds the heel of the foot and the Achilles tendon at the appropriate place.
Since the U-shaped frame (u1) is the same height as the sole position (B4) where the foot is placed, normally or in a state before being worn (as described above, it has a shape that matches the outer shape of the shoe sole, (Since it is a slightly larger U-shaped frame), you will not get in the way when you put your foot into the sandals.
When you are in a hurry, like a sandal with a string, you don't wear it while stepping on the string. Make a U-shaped frame (u1) when necessary.

The frame (u1) is movable at the frame connection position on the rubber bottom by starting the circle around the screw fastening spacer (B3).
Connect the lead-in frame (F) from the front to the appropriate location (u4) from the screwing position (B3) to the rear (u3) of the U-shaped frame. To connect, pull the pull-in frame (F) forward in the connection, the U-shaped frame (u1) will stand up, and the rear part (u3) of the U-shaped frame will hold the area around the upper part of the heel and heel. The pull-in frame (F) pulled forward is attached and fixed to the Velcro (B5).

The U-shaped frame (u1) is made of a hard material and there is no distortion, so the pulling force of this retractable frame (F) moves the U-shaped frame (u1) directly. In addition, the material of the pull-in frame (F) uses a plastic plate material with a firm bending force.

The pull-in frame (F) and the U-shaped frame (u1) are connected as close as possible to the screwing position (B3) in the middle from the screwing position (B3) to the rear part (u3) of the U-shaped frame, The rear part (u3) of the U-shaped frame of the U-shaped frame (u1) moves more than the retracted distance of the retractable frame (F) so that the rear part (u3) of the U-shaped frame can move, and the retractable frame (F) can be operated with a small movement. To.
In Fig. 1, it is connected to the lead-in frame (F) at a position (U4) about 1/3 of the length of the U-shaped frame (u1). This pull-in frame (F) U-shaped frame (u1) connection is at one place on either the inside or the outside of the foot. By doing so, you can hold around the buttocks and the upper Achilles tendon by pulling the pull-in frame (F) once.

Attach one side of the Velcro to the front part (F2) of the retractable frame (F) and paste it on the sandal surface (B5) to which the other side of the Velcro tape is attached. The U-shaped frame (u1) It is fixed at the position where it is pressed around the upper Achilles tendon.
To release it, remove the Velcro and push it back to return the U-shaped frame (u1) to its original position, that is, the same height (B4) as the rubber bottom.
As mentioned above, the retractable frame (F) is also a hard material, so it can be pushed back by the retractable frame (F).
If the Velcro is fixed at the returned position, the U-shaped frame (u1) is also fixed at that position.
Fig. 1 (Fb) shows the pull-in frame (F) holding band. As shown in Fig. 14 (Fb), it will serve as a downward stopper for the U-shaped frame (u1).
(St) is also a stopper, but (St) can be selected as an alternative.

The spacer (B3), U-shaped frame (u1) and retracting frame (F) screwed into the frame connection position on the rubber bottom are also made firmly.
The rest is Velcro, but if the connection surface is enlarged as shown in Fig. 13, it will be firmly fixed, so that people with weak body functions, especially those with weak legs and those who need nursing care, will be safe without worrying about coming off. It is possible to wear with care.

The above is for sandals, but the shape of the shoes may be required for the same function. In the case of clothing coordination, cold, rain, etc., the sandals can be diverted if it is necessary to have the same appearance as the shoes, as well as the convenience of putting on and taking off and a safe structure.
In that case, if the fabric is stretched from the U-shaped edge of the U-shaped frame to the U-shaped edge (u5) between the rubber bottom and the sole, the appearance from the middle part of the shoe to the heel part may be covered. Is possible. 8 to 10 are external views.
If necessary, you can wear up to about 21.

Figure 12 shows the storage of the fabric. The U-shaped part of the U-shaped frame (u1) is made larger than the U-shaped part (Bu) of the rubber bottom. When the U-shaped frame (u1) is folded, the cloth (N1) bent in the gap (S1) is stored.
In that case, it is necessary to slightly widen the gap (S1) between the U-shaped part of the U-shaped frame (u1) and the U-shaped part (BU) of the rubber bottom compared to sandals that do not use fabric. .
If you do not want to increase the gap (S1), use as thin a fabric as possible.
If you don't want to make a lot of deflection, you can use a highly elastic fabric such as knit fabric. In that case, you can also use a thick fabric to take measures against the outside air such as cold.
If you do not want the appearance to look poor, you can cover the U-shaped frame (u1) with vinyl or leather. The outside of the U-shaped frame (u1) is not related to storing fabric, so it can be thickened. FIG. 12 (u6) part.
If necessary, it is possible to make it look like ordinary shoes as shown in Fig. 21.

If rubber or a spring is connected to the tip of the retractable frame (F) as shown in Fig. 17, both sandals and shoes can be made more convenient and removable.
Until now, attach one side of the Velcro to the tip of the pull-in frame (F), and attach and fix it to the sandal surface (B5) where the other side of the Velcro is also attached, and fix the U-shaped frame (u1). It was fixed at the position where it was pressed around the Achilles tendon on the heel, but the magic tape was stopped, and instead the rubber (Fig. 17G1) or spring (Fig. 18G2) was attached to the tip of the retractable frame (F). If the part is fastened to the tip of the sandal or the shoe (FIG. 17B6, FIG. 18B7) or an appropriate place and the force of the rubber (FIG. 17G1) or the spring (FIG. 18G2) is applied to the retracting frame (F), the force is Stand up the rear part (u3) of the U-shaped frame connected to the pull-in frame (F) at a position where you can hold the Achilles tendon around the buttocks You.

The rubber (Fig. 17G1) or spring (Fig. 18G2) is always connected, so the U-shaped frame (u1) is always up. However, when you try to put your foot in the sandals or shoes and get weight when you are in the buttocks, the pressure will cause the U-frame (u1) to drop immediately. (Fig. 19)
Since it falls to the maximum, sandals and shoe sole (B4), you can insert your feet without difficulty.
In the case of ordinary shoes, it may be difficult to put your foot in the buttock, or if the type has a band on the heel of the sandal, it may remain on the band, but this is not the case. If the return force is weak, there is no problem if you change the design of the rubber (Fig. 17G1) or spring (Fig. 18G2) force or have an adjustment function.

In addition, there is no problem with worrying about whether you can take off when walking. It seems that the force to take off the foot is applied to the position slightly above the horizontal direction.
When the position of the U-shaped frame (u1) is located at the highest part of the ridge (FIG. 20), a part of the ridge (FIG. 20K1) is the upper edge of the U-shaped frame (u1). In this case, the rear part of the U-shaped frame is in a sufficiently raised position (FIG. 20u3), rather the lower edge of the U-shaped frame (FIG. 20u12). It will be in the form of pushing up, so you can not take it off.

If the U-shaped frame (u3) is always in contact with the heel or Achilles tendon in conjunction with the rubber spring force, it will look like a shoe rub, but it can be designed or adjusted so that it stops at a predetermined position. (Fig. 20St2) If it is done, there is no problem.
St2 in FIG. 20 is one example of a method for adjusting the return height of the U-shaped frame (u1) by connecting it with a screw attached to the middle part of the U-shaped frame (u1) and a thin string. Fix it with the string attached to the envelope.
A chain-like shape with several holes can be considered, but if that is not possible, the subtle positioning can not be done, but if this is the case, the string can be positioned freely with the length of the string.
Also, since the material is soft, it can support the movement of U-shaped frame (u1) that moves up and down with a spring. A velcro is attached to the end of the string (St3) and can be fixed at any position (St4). If you tighten the screws that tie the string further, you can do it more fully.
Alternatively, in FIG. 14, the lowering position of the U-shaped frame (u1) is suppressed by the pull-in frame holding band (Fb), but the rising position of the U-shaped frame (u1) can also be adjusted at the position of (Fb2). The

It is time to take off the shoes and sandals, but ordinary shoes are tightened with shoelaces, but the proposed shoes are restrained with rubber or spring force, so the heel presser frame can be easily lowered, so it is easy You can take it off. Moreover, although it is a bit rough, you don't need to bend every time if you take off your heels with your shoes.
And after taking off, it immediately returns to its original shape.

If it is assumed that shoes using rubber (FIG. 17) or springs (FIG. 18) are basically not worn with sandals like a sandal, then stepping on the buttocks, that is, U-shaped frame (u1 ) Or press down on the buttocks.
Figure 21 is closer to the appearance of a normal shoe than Figure 8. The Achilles tendon is enlarged to eliminate the weakness, and the (u4) part of the retractable frame (F) is enlarged to eliminate the excessively open gap, and the retractable frame (F) itself is also hidden. Fig. 22 shows the inside.

Figure 4 is an illustration of each connection. The connection between the U-shaped frame (u1) and the retractable frame (F), B3 indicates the connection between the U-shaped frame u2 hole and the spacer embedded in the sandal body.
Both have a structure with a gap so that it can rotate, and the spacer of B3 is firmly screwed into the rubber bottom.

The invention's effect

Sandals are easy to remove at any time, but they are not suitable for long distances and short runs because they are worn on the other hand.
However, sometimes you may want to use it for long distances or for short runs or to fix it to your feet.
In the case of conventional sandals, the type without the fixed band cannot of course cope with the above situation, but the type with the fixed band also takes time and effort to put on the band.
However, the proposed one can usually be worn as sandals and fixed only when necessary.
There is no need to fix it.
I was able to compensate for the disadvantages of sandals.
The sandals can be used as shoes by covering the buttocks with a cloth.
In that case, if you wear it as sandals, the effect is the same as above. If you pull the fixing band to fix the buttock, the heel covered with cloth will be set.
Of course, it is convenient for ordinary people as easy-to-wear shoes, but it is useful to be able to put on and put on easily if you have weak legs or are in need of nursing care.
It is fixed with Velcro, but if the adhesive surface is sufficient, it can be firmly fixed, so there is no problem with safety.
The above is a manual fixing method using Velcro, but by changing the Velcro part or method to rubber (Fig. 17G1) or spring, it is possible to make the sandals and shoes more detachable and convenient. I can do it.
The frame of the heel part stands up with rubber or spring force, but when I put weight on the sandals or shoes and put weight on the heel, the U-shaped frame (u1) immediately Go down. (Fig. 19)
Since it falls to the maximum, sandals and shoe sole (B4), you can insert your feet without difficulty, and you can easily remove it when you take it off.
