Abstract

PROBLEM TO BE SOLVED: To solve a problem in which fitting an article of footwear with a thong has to be performed by a specialist because, in the footwear with a thong, there is a general operation in which ends of a thong are force-fitted in the base of the article of footwear by using a professional implement (fitting tool) or in which ends of a thong are fixed from the reverse side of the base in which the thong is fitted, where these are the operations confined to a specialist having professional knowledge and tools, where as a result general users have to purchase footwear with a thong in which a thong is already assembled in the base of the footwear, and where general users have to ask the specialist to fit the footwear with a thong by order if no products with different color patterns are displayed.SOLUTION: An integrally formed flange is provided in the ends of a thong and, with this flange long-shaped, thong-fitting is made possible by twisting the ends of a thong and manually pushing it into the base of an article of footwear with a thong. After the fitting, by restoring the twist of the ends of the thong, the flange at the tip of the thong can be fixed on the base. Also, by bending the long-shaped flange with a tensile force of the hand, or by guiding the flange into a flange insertion hole having the same shape as the flange, the thong can be removed by hand from the base of the article of footwear.

Description

The present invention relates to footwear with sandals such as clogs, sandals and sandals, which can be easily replaced with bare hands by a general user without using a specific insertion tool. The present invention relates to a footwear with a nose and a footwear with a nose made of the foot and the foot.

Conventional footwear with a umbilical cord requires special know-how in using a special tool such as an insertion tool when inserting the umbilical cord into a table, or using a lanyard first in a manufacturing factory. At the store that sells footwear with umbilical cords, it sells and repairs with the umbilical cords inserted into the table.
In this situation, the user needs to carefully select a combination of lanyard and pedestal color patterns, and even if it was originally purchased as good, it would be unfortunate that it would not suit as the clothes changed. There are many. The most common type of Japanese clogs are clogs at the beginning of purchase, painful legs, and loose patterns while you continue to use them. There is no choice but to ask the store.
On the other hand, with the diversification of customer needs, original footwear is also required for general footwear. In recent years, footwear that can be decorated after purchase in pursuit of its own originality has become a huge boom. It was. Even if it is ideal to have various footwear with different images according to the situation and fashion when using footwear, I want to make fashion coordination that I can not decide without circumstances of home and household, storage place and sense However, there are many people who have no choice but to use a few safe footwear because they do not match each other. Even in such a situation, many people who want fashion in footwear have a unique decoration or want to assert themselves by having footwear with unusual colors and designs, and even in footwear with nose, the design is People will be pleased if they have good, unique and easy-to-coordinate footwear, and it will be even more ideal if there is footwear that can be re-imaged by general users after purchase. There is a potential need for replacement.

Patent Document 1 (Japanese Patent Application Laid-Open No. 11-164709) is a prior art that allows a general user to easily replace a chord without using a specific insertion tool.
In Patent Document 1, the first locking tool and the first holding body are provided in front of the umbilical cord and fixed to the base by screwing, and the back of the nasal cord is engaged with the second holding body at a position having a different length. A detachable locking piece is provided, and the locking piece at the tip of the back is locked to fix the umbilicus to the base and to adjust the length of the umbilical cord. As a result, even a general user can insert the cord, and the length of the cord can be adjusted at the position where the locking piece is hung.
However, this method does not stay on the back side of the base simply by passing the cord through the hole in the base, and it is necessary to return the base to the back side in order to fix the back, There is a possibility that the thong will fall out to the front side during the fixing work.
As for the way to fix the cord, it is easy to screw it when locking only the beginning, but when the cord is pulled to the front side of the base with the human foot, a long groove provided on the back side of the base Even if a long cap nut is fitted, the cap nut may come out of the long groove toward the ground when footwear is not used, and the combination of male screw and female screw is loosened by vibration anyway. It cannot be said to be secure. In the latter part, the cords on both sides must be pulled to the center to hook the ring (the locking piece at the tip of the nose) into the hook shape of the locking piece of the second holder, and it should have been inserted during the locking operation. Even if one of the back part comes out to the front side, it takes time, and the ring that has been locked is the hook-shaped bent part of the hook, although it requires a force to pull it to the center when hooking the hook-shaped tip Because it has no choice but to settle down, it has to be completed after it is fixed to the base with the chord that should have been tightened slightly slightly loosened.
In addition, the second holding body that locks the back has only to lock the nasal cord in the state of being attracted to the back of both sides in the center of the base, and the two backs are equal in length to the base. It will be fixed, and the left and right lengths of the back cannot be adjusted separately according to the height or deformation of the instep of the user.

Next, Patent Document 2 (Special Table 2013-509246) has a feature that a general user can easily insert a cord (a strap in this document) into a corresponding footwear table without using a specific insertion tool. ing.
However, the ends of the umbilical cord of Patent Document 2 are each configured in a plurality of separable shapes, and the nasal cord ends (the separable portion of this document) need to be inserted into the holes in the table while operating one by one in several steps. Each time a piece is put into the hole, the hole becomes cramped, and it takes time to settle the shape to the position where the separable part should be at the fixed position of the hole while pushing and pulling the separable part. In order to finish fixing the thongs in the three holes provided on the table, “insertion of the number of holes × multiple times” is required, and it takes time to fix the thongs.
In addition, because the shape of the cord is complicated, the production cost of the cord is increased, and at the same time, the length of the cord can be changed depending on the set position by providing a plurality of holes in front of the table. In addition, it is not good to see unused holes in front of the footwear with nose, and it is necessary to change the length of the nose because the wall thickness is enough to withstand the load. We have various problems such as being unable to do so.

Patent document 3 (utility model Sho 56-2804) is a device that inserts a snare on a footwear made of rubber (it stands in this document). Is shown. By holding the projecting part of the large umbilical cord with a device and pushing it into the small hole provided in the table with the power of the machine, the end of the large umbilicus cannot escape from the small hole in the table and the lanyard is fixed to the table Is done.
In order to push the end of the cord into a moderately flexible base such as rubber material, even if the end of the nose is larger than the hole in the base, the hole in the base is pushed sideways and mechanical force is combined to insert the cord However, once the umbilical cord inserted into the table is designed so that it can not be easily removed for safety reasons, the footwear must be sold with the lanyard attached. It's real. Even if it is necessary to replace the cord, even if it is pulled out with great force, the hole in the base is damaged or widened, and the cord cannot be inserted again. There is no choice but to recycle the footwear platform and cord.
In contrast, the present invention provides a structure in which a nasal cord having a simple structure with high productivity and a footwear with a umbilical cord can be easily replaced by a general user.

JP-A-11-164709 Special table 2013-509246 Utility model 56-2804

In general, it is difficult for the user to insert the umbilical cord in the footwear with the umbilical cord, and it is usual to bring the footwear into the footwear store and insert it. In other words, footwear with cords that are currently on the market use a unique jig called an insertion tool when inserting the cord on the table, or while adjusting the length of the cord with professional intuition. It is in an environment that requires special techniques to fix the umbilical cord.
According to the patent document of the prior document, it seems that there are some inventions in which the user can insert the cord, but the structure is complicated, and it seems that the difficulty still remains for an amateur to insert the cord.

In particular, it is not a situation where footwear with a umbilical cord and a stand are sold individually to general users, but a footwear store and a favorite lanyard and pedestal can be specified and custom-made. From the finished footwear with a nose, it is in an environment where it can be purchased by selecting from the finished footwear in consideration of appearance and comfort. Even if the general user wants to coordinate their footwear according to the situation and fashion, such as going out and clothing, it is necessary to give priority to shoes used daily, there are no home and household circumstances, storage space etc. For this reason, I have to give up having various kinds of footwear with snares in various variations.

In addition, shoes and so on are compatible with various foot sizes, and there are footwear that has a function to fit the height and width of the foot of each foot by tightening the shoe straps and fasteners. Although there is prior art that adjusts the length of the umbilical cord for footwear with a umbilical cord, the instep of the human foot is not uniform on the inside and outside, and some people have different left and right foot sizes. Because there are people, the length of the umbilical cord along the inside and outside of the foot is uniform because of the general shape of the umbilical cord, so the length of the umbilical cord is adjusted according to the characteristics of the foot for each user. It is ideal if it can be adjusted with.

Footwear with umbilicals and flexibility in umbilicals, such as flip flops, make the end of the umbilical cord about twice as large as the hole in the pedestal so that the umbilical cord will not accidentally come out of the pedestal due to a load during walking. Therefore, it is not possible to insert the cord on the table without using a special insertion tool such as Patent Document 3 of the preceding document. In the unlikely event that a force is applied to pull the cord from the table, the hole in the table spreads or cracks occur, damage such as tearing of the cord occurs, and it is impossible to use the cord or table again It is.
There is the footwear of patent document 2 of the previous document as a umbilical cord that can be inserted by a human hand, but it is complicated and troublesome to insert the end of the umbilical cord into one hole of the base by multiple operations of multiple separation pieces. Work. For footwear with snout, the three ends of the thong must usually be inserted into three holes, and in order for the user to be able to attach and detach the thong to the table with less work, it is easy to understand. It is desirable that each of the ends be detachable in one hole by one operation.
Further, as in the prior art document 1, even if each of the ends of the cord is inserted into the hole of the table by one operation, the end of the cord inserted from the front side of the table is quickly fixed on the back side of the table. However, it is necessary to fix the end of the umbilicus inserted into the hole of the base on the back side of the base, and there is a possibility that the end of the nose is pulled out to the front side of the base in the middle of the operation.
As described above, various problems still remain for a general user to attach and detach the garment with the umbilical cord.

In solving these problems, rubber footwear and EVA material footwear with moderately flexible footwear, with rubber materials and resinous cords that are also moderately flexible, are mainly used. In the case of commercially available products, beach sandals and cushioned clogs.
In the invention of the present application, the heel of the umbilical cord is changed from a conventional circular shape to an elongated shape so that it can be inserted into a footwear footwear with a umbilical cord by one push of a bare hand. The base is provided with a hole that looks like a “convex” cross section, and the upper small diameter is the 鍔 insertion hole and the lower large diameter is called the 鍔 fixing hole. As seen from the side, when it is molded in the shape of the letter “T” and the cord is inserted into the table, it is necessary to twist the heel and temporarily push the heel into the shape of the letter “I” along the neck. The end of the umbilical cord can be inserted with a bare hand into the cushion insertion hole. The end of the umbilical cord that has passed through the small-diameter hook insertion hole in the shape of the letter “I” returns to the original “T” shape by entering the large-diameter hook fixing hole, and the convex large A ridge is caught in the step between the diameter and the small diameter, and the umbilical cord can not be easily removed from the table, so the umbilical cord can be inserted into the table and fixed with a simple push of the hand.

If the base is made of a hard material such as wood and does not change as the EVA material temporarily expands, the shape of the base insertion hole of the base is the same as that of the base. It has a shape, but its orientation is 90 degrees rotated from the time when the original umbilical cord has been inserted, and the heel fixing hole connected to the heel insertion hole is the direction in which the original nasal cord has been inserted. It is provided with.
When inserting the umbilical cord into the table, twist the end of the umbilical cord 90 degrees from the original direction (the direction when the insertion is completed) and insert it into the heel insertion hole. If you put the bag back in its original orientation and guide the bag into the bag fixing hole, the cord will be fixed by inserting it into the base with your bare hands.

Next, when removing the umbilical cord from the pedestal, if the pedestal is made of a cushioning material such as EVA and the ligament is made of a material that bends when applied with an external force such as polyvinyl chloride (PVC), forcibly pull the nasal cord from the pedestal. As a result of the operation, the heel insertion hole of the EVA material temporarily expands, and the heel at the end of the umbilical cord curves into the shape of a “f”, making it possible to remove the nasal cord from the platform.
Predicting the balance between this force to pull out and the force applied when using footwear, ensure the thickness and size of the heel cord, the flexibility of the heel and neck, and the size of the heel insertion hole on the table If the product is designed in this way, there is no problem when using footwear with a snout, and when replacing the snout, even if it is forcibly pulled out with the help of a human hand, it will be reused without any damage to the thong or the base (again It is also possible to insert the cord on the table.

Also, if the base is made of a hard material such as wooden and has a long heel insertion hole like the chin cord, to remove the umbilical cord from the pedestal, push the heel in the heel fixing hole to the back of the table, By intentionally rotating the end of the nose 90 degrees and guiding the eyelid in the direction of the eyelid insertion hole, it is possible to easily remove the nose.
In general, when wearing footwear with a thong, the direction of the thong cannot rotate 90 degrees from the original direction, and the thong does not come off the stand unless it is intentionally attached or detached.

In this way, the shape of the heel at the end of the umbilical cord is elongated, and the heel insertion hole and the heel fixing hole of the footwear with the umbilical cord are prepared so that it can be easily fixed so that the ridge of the umbilical cord can be easily inserted. The cord can be attached / detached and fixed with the bare hands of the present invention.
In addition, the reason why the shape of the heel insertion hole and the heel fixing hole is rounded in Example 1 described later is also because the manufacturing processability of the EVA material base is good. This is the shape used for ease.
The oblong hole of the second embodiment is another realization means for attaching / detaching the nose to / from the base with bare hands even in the case of a base made of a hard material having no flexibility such as EVA.

Further, in the present invention, a reinforcing member is prepared.
Use a reinforcing member to prevent the long heel from playing in this space when the heel fixing hole is provided in a round shape, and to prevent the nasal cord from inadvertently escaping from the heel insertion port due to the flexibility of the chin This ensures that the thong is firmly fixed.
In order to make it easier for ordinary users to handle the reinforcing member, it is prepared with a structure that can easily surround the ridge at the end of the umbilical cord, and after being inserted into the base, it is attached to the end of the umbilical cord and stored in the heel fixing hole. This prevents the ridge of the nose from being bent and prevents it from coming out of the base easily.
This reinforcing member waits for an opening to be inserted across the neck of the umbilical cord and surrounds at least three surfaces of the ridge of the umbilical cord, so that the heel can be fixed in a T shape with respect to the neck, and the force for pulling the nasal cord from the base is applied. However, by preventing the beak from bending, it further reinforces the fixed state of the end of the nose so that it does not come off the table.
This member is made of a hard member such as polycarbonate (PC), polypropylene (PP), ABS resin, metal, etc., and serves as a reinforcement for preventing the escape of the cord due to the flexibility of the table and the cord.

Moreover, in this invention, the adjustment member which can adjust the length of a umbilical cord in each of the beginning and the back is prepared.
When the ridge of the umbilical cord inserted into the pedestal fits in the heel fixing hole, by inserting an adjusting member between the heel and the pedestal, the ridge (the part that can be seen on the person's foot) that appears on the front side of the pedestal footwear The length can be adjusted. Adjustable members can be attached to the front, right back and left back of footwear with foot cords, and the left and right sides of the cord can be adjusted to different lengths, so that it can be adjusted to the shape of each person's foot. It becomes possible to adjust the length of the thong.
The adjusting member can be provided by providing the reinforcing member with various thicknesses.

Thus, in the present invention, it is possible to provide footwear with a new idea that can be attached and detached to and fixed to the base with bare hands, a reinforcing member that can fix the nose safely without specialized knowledge, and each foot By adjusting the length of the umbilical cord that matches the shape of the footwear, the footwear with the umbilical cord can be sold in the assembled state as usual, as well as the sales of the umbilical cord only, and the footwear with the umbilical cord that uses the umbilical cord In addition, it is possible to provide individual sales forms, such as footwear, and users can provide footwear with new nose and its sales form so that users can enjoy footwear by placing a nose tailored to their mood and fashion on the platform of their favorite color It is what.

According to the present invention, in order to insert the cord into the insertion hole of the footwear table, it is possible to insert the cord into the table by twisting each end of the cord with a human hand and pressing it once. Since the umbilical cord is fixed to the pedestal when it fits in the heel fixing hole, the umbilical cord is fixed to the pedestal at the same time that the umbilical cord is inserted into the pedestal only by performing three operations on the three folds of the pedestal. be able to. Such operational operability is an effect that cannot be obtained in Patent Document 1 or Patent Document 2 cited as the prior art.
In addition, the shape of the ridges of the umbilical cord at this time is simply a T-shaped monolithic structure when viewed from the side, and the shape of the umbilical cord is simple, so the manufacturing cost is low and the mass production is easy. It becomes possible to provide an excellent thong.
In particular, if the base is a hard material such as closed cell foam sponge (EVA) but also has cushioning properties, and the nose is made of a moderately flexible material such as polyvinyl chloride (PVC), the end of the nose It is easy to twist with a bare hand temporarily, and the insertion hole of the base expands somewhat with the force of pushing, so it is possible for women to pass the end of the nose through the heel insertion hole prepared in the base It is. Then, when the heel is inserted into the heel fixing hole connected to the heel insertion hole, the heel at the end of the nostril returns to its original shape and is fixed to the base. In other words, the end of the umbilical cord has two sideways, and it is pulled to the front side of the table (the side on which the person's feet rest) in order for a person to wear it and walk. Is pulled back and the hook of the cord is always caught at the step with the hook fixing hole connected to the hook insertion hole, so that it cannot be easily removed, so that the cord is fixed in a state of being inserted into the table.
Further, in Example 1 of the present application, a reinforcing member is prepared with a resin or metal such as polyester or ABS, which is a harder material than closed cell foam sponge (EVA), and by enclosing the heel at the end of the nose Deformation is prevented, and the umbilical cord will not come out unless force is applied to the end of the umbilical cord, the heel insertion hole of the base or the reinforcing member, so that the footwear can be used with confidence.

If you want to remove the thong from the table, the resin such as polyvinyl chloride (PVC) has moderate flexibility, so if a strong pulling force is applied, the long folds will bend into a "he" shape. , Can be pulled out from the hole insertion hole.
When the cord is reinforced with the reinforcing member described in this application and the cord is fixed to the table, push the cord from the front side to the back side of the table, and remove the reinforcing member exposed from the heel fixing hole of the table from the end of the cord. After that, the cord can be removed by pulling the cord to the front side of the table at once. In this case, if the base is an closed cell foam sponge (EVA), it is a hard material, but also has cushioning properties, and when external force is applied, the heel insertion hole is appropriately expanded, so that the woman's general force pulls out the thong It becomes possible.

Moreover, in Example 2 of the present application, an example is shown in which the umbilical cord of the present invention is mounted on a footwear with a umbilical cord made of a material that is difficult to deform by human power, such as wooden. However, a long heel insertion hole is provided in the base so that the thong can be inserted in a direction rotated about 90 degrees, which is different from the original direction of footwear with a thong. Fix the cord on the table by turning it back and guiding the heel to the heel fixing hole.
When removing the umbilical cord from the table in Example 2, the end of the umbilical cord is pushed into the back side of the pedestal, the heel is taken out from the heel fixing hole, and rotated in the direction of the heel insertion hole (for example, rotated 90 degrees). The cord can be removed from the table by guiding it to the side, so that it can be easily replaced with the power of a human hand.

In this way, all three ridges at the end of the umbilical cord are inserted by twisting the end of the umbilical cord with a human hand, returning it to its original orientation and guiding it to the heel fixing hole. The three ends of the umbilical cord can be inserted and fixed in three places in the insertion hole three times, making it possible for users without expertise to easily replace the nasal cord, and to intentionally remove the nasal cord. Unless otherwise, the thong will not come off the base during normal use. And in order to further reinforce the fixation considering the flexibility of the table and umbilical cord, the reinforcement member is inserted into the end of the umbilical cord with the ridge of the umbilical cord pushed out to the back side of the table, and the umbilical cord is pulled up to the front side of the table, By simply reinserting the reinforcing member surrounding the heel into the heel fixing hole, deformation due to the flexibility of the heel is prevented, and the cord is firmly fixed to the table. This is also very easy to handle for general users, and can provide footwear with a cord that can easily change the cord.
When removing the umbilical cord from the stand, it can be easily operated simply by pulling it out, or by simply rotating the end of the umbilical cord from the heel fixing hole toward the heel insertion hole and pulling it up. It has a structure.

As an example of the present thong, preparing the thong with a resin such as polyvinyl chloride (PVC) has the flexibility to twist the end of the thong with the hand of a human as described above. It is easy to handle with a push of a bare hand and can be attached to and detached from the table, and since the umbilical itself is a molded product, it can be mass-produced in a variety of colors. It is possible to print on this thong.
It is possible to print scan data of photos and fabrics as well as Japanese-style Western patterns, so for example, if you can print the pattern of swimsuit fabric on the sandals of beach sandals, you can team up for the Bon Dance Tournament It is possible to provide footwear with a thong that is full of originality, such as participating in a clog with a name and mark printed on the thong.
A variety of color patterns can be printed according to the user's wishes, and a stand on which to insert them can be supplied individually, and it is easy for the user to change the combination according to their preference and need. If it can be done, a new way to use footwear with nose will be created.

Further, in the present invention, by changing the thickness of the reinforcing member or using the adjusting member, the position where the end of the cord is fixed in the table can be adjusted to be shallower or deeper. This allows the user to easily adjust the length of the umbilical cord that appears on the front of the footwear with lanyard, so that the umbilical cord can be adjusted according to the height and width of the instep of each user, the shape of the foot by wearing a socks, etc. The user-friendliness is greatly improved by freely adjusting the length.
The height of the instep of the human foot is not uniform on the inside and outside, and there are people with different left and right foot sizes, and some people have deformed, but the general shape of the nose is on the inside and outside of the foot In general, the length along the line is made uniform and cannot be matched to the characteristics of the foot for each user. If the length of the umbilical cord can be adjusted by using an adjustment member in each of the three holes of the base that fixes the end of the umbilical cord as in the footwear of the present application, Since the height can be adjusted individually, the length of the cord can be changed on the inside and outside of one foot to fit the foot. This can be adjusted not only according to the deformation and characteristics of the foot, but also by adjusting the length at each end of the nose. For example, there are about 25 to 25 cm foot sizes for women's feet. It is possible to cope with a foot size of 21 cm to 25 cm only by preparing the umbilical cord and adjusting the length of the umbilical cord with the adjusting member.

The invention of the present application is characterized by the umbilical cord of the footwear with a umbilical cord, and the footwear with the knitted footwear is prepared in a corresponding form. Needless to say, it is possible to sell the stand alone or sell only the thong as footwear with a thong that allows the thong to be freely exchanged.
This means that even if the user has only one stand, it is equivalent to having a large number of footwear by exchanging thongs, and if the stand has a different color or shape, The combination of the base and multiple umbilical cords makes it possible to properly use footwear with umbilical cords that have a different atmosphere several times.
Being able to provide the platform and cord separately, users can freely combine the platform of various colors, patterns and shapes, and various color patterns and shapes, and users can freely combine them with their own preference. You can set footwear, and there is a pleasure to freely customize the footwear according to the occasional situation, such as the type of clothing, color pattern and whereabouts. The ability to change the cord with bare hands means that, for example, you can exchange footwear with a colorful chord with Western clothing in the daytime, exchange it with a chic chord at night and bring it to the kimono, etc. Thus, a plurality of footwear variations can be produced on a single footwear base by exchanging the footwear base and thong suitable for the situation by a user's hand.
In particular, there are various footwear with thongs, from typical clogs to sandals, snow sands, sandals, etc., and it is possible to use common thongs across genres for these various genre bases. According to the present invention, it is possible to provide footwear with a new sense that can be easily replaced on the user side.

By making the ridges of the umbilical end longer than the conventional round shape, twisting each end and temporarily reducing the size of the ridge of the umbilical cord to be inserted into the heel insertion hole of the platform A cord that can be inserted into the table, and that can be removed from the table by bending the heel with the pulling force of a bare hand and a table on which it can be inserted.
By having a reinforcing member to fix the umbilical cord securely to the table to compensate for the flexibility of the umbilical cord, and further having an adjusting member that can adjust the length of the umbilical cord that appears on the foot on the table surface, The embodiment of the first embodiment in which the combination of the umbilical cord and the table can be easily exchanged while the umbilical cord is securely fixed to the table and the length of the umbilical cord can be adjusted.
And, like the heel, twist the end of the nostril on the base with the long heel insertion hole, put the heel along the heel insertion hole, connect it to the hole and change the angle to the heel fixing hole. Example 2 where the umbilical cord can be inserted into the table by guiding the heel, and when removing the umbilical cord from the pedestal, the ridge is removed from the heel fixing hole, the end of the umbilical cord is rotated, and the umbilical cord can be removed from the table by guiding it to the heel insertion hole. Form.
In order to easily change the combination of these cords and platforms, the cords can be inserted into and removed from the platform with the help of human hands, and the flexible cords and the reinforcing members that securely fix the platform, and the length of the cords The present invention proposes footwear with a thong and thong having an adjustment member for changing the shape.

In the description of the present invention, two types of footwear-attached footwear structures are used as objects to which the cord of the present application can be inserted.
The invention of Example 1 is a material that is hard to some extent but has cushioning properties, such as closed cell foam sponge (EVA foam), and can be slightly deformed locally when external force is applied. This is an embodiment in the case of using a member that is flexible and can be restored if no force is applied.
The invention of the second embodiment is an embodiment when the footwear with nose is made of a harder member such as wooden.
In addition, although Example 1 and Example 2 are described as one example, each member utilizes the structural characteristics of the present application in the characteristics of the member described in the example, and the same effect is produced. If there is, it is not limited to the members described in the embodiments.

FIG. 1 is a diagram for explaining the thong of the present invention.
In FIG. 1, the umbilical cord (2) is provided with a forehead (21) sandwiched between the thumb and forefinger, two left and right side crossings (22), and a left and right backside (23) ahead thereof. The umbilical cord (2) is formed at the end of the anterior (21) and posterior (23) by making the shape of the end surface of the heel (24) provided as a T-shaped monolith into an elongated shape. Each ridge is twisted with a person's bare hand so that it can be inserted into the table, and the thong is fixed to the table.
Here, the shape of the end face of the heel is long. When viewed from the side of the neck (25) of the three chin cords (2), the heel (24) is molded into a single “T” shape. For example, the shape of the upper surface if it is represented by the letter “T”, and the shape of the surface of the end portion of the nose as viewed from the bottom in FIG.
Many of these ridges are made in a round shape with conventional swords (beach sandals, etc.), and they are fixed by inserting them into small holes on the table at once with a jig such as an insertion tool. A shark that has passed through a small hole is safe even when walking, but it cannot be inserted into the table with a human hand without using a tool such as a tool. Details of the bag (24) of the present application will be described in more detail later in the description of FIG. 3 and the end of the first embodiment.
By the way, the umbilical cord (2) of this application is made of polyvinyl chloride (PVC), etc., and because of its flexibility, the end of the forehead (21) and the end of the back (23) can be twisted with human hands. However, as long as the edge of the umbilical cord can be twisted with bare hands and no external force is applied, the ridge is naturally restored to its original shape. good.
According to the present invention, the ridges (24) at the end of the umbilical cord are inserted into the heel insertion holes of the footwear with the umbilical cord described later in FIG. It is an invention of a umbilical cord that can be fixed to a table, and is a footwear with a umbilical cord in which the umbilical cord is inserted, or a footwear platform with this umbilical cord.
As an aside, the thong made of polyvinyl chloride (PVC) can be mass-produced in a variety of colors because the thong is itself a molded product, and it is also possible to print different colors and new patterns from the beginning. It is possible to provide a thong with a variety of color prints with a design that suits the user's preference.
If you can insert and fix the umbilical cord with your bare hands without using a specialized umbilical cord insertion tool or jig, a single user will have multiple lanyards of various designs for one piece of laced footwear. In accordance with the situation of wearing footwear with nose, such as mood and fashion coordinates, users can easily exchange the snout with their own hands each time and enjoy one footwear with a nose as different footwear.

Clogs and flip flops are common for footwear with snouts, and in the present application, they are explained with the image of clogs. It is common to keep wearing these footwear with the combination of the thong and the base set at the time of purchase, and the next footwear is obtained for reasons such as being damaged, getting tired, or unable to wear because the size does not fit, but at the time of purchase The color pattern of footwear that I thought was good for the clothes doesn't look good with any color pattern, and some people buy more than one footwear, and those who continue to wear with one foot wear the elements of fashion coordination There are many cases that are no longer required.
This application makes it possible to replace these clogs such as clogs and flip flops with bare hands at any time.For example, at a beach where you went out on the weekend, walk along the beach with a swimsuit and footwear with a matching color printed on the matching color pattern. In the evening fireworks display, you can change to a yukata and see the fireworks in footwear with a Japanese pattern. In this way, by having one table and multiple thongs alone, it is fun to change the thong with clothes and mood at that time, and use footwear with various thongs according to the situation, If you have a table with a different shape and color, the combination of the thong and the color of the table will swell several times. Also, for example, when purchasing footwear of the same kind as a family or a friend, the combination of the umbilical cord and the pedestal can be increased several times by exchanging or lending multiple umbilical cords. In addition to the pleasure of coordinating with clothes according to the situation, it is possible to show how well the common footwear is combined, and the topic of fashion coordination and variation ideas can be activated, which can also stimulate communication.

FIG. 2 is a perspective view of the footwear (1) with a nose according to the first embodiment.
As shown in FIG. 2, the footwear (1) with the nose of Example 1 is composed of a base (3) for attaching / detaching the nose (2) of FIG. 1 and a reinforcing member (4) used as necessary. This is shown in the figure.
On the base (3) of the footwear (1) with umbilical cord, the cross section can be seen as a “convex” character to insert the umbilical cord (2) forehead (21) and two posterior (23). A large and small round hole is provided, and the small diameter hole is a heel insertion hole (33) for inserting the heel (24) at the end of the umbilical cord (2). It is a hook fixing hole (34) for storing and fixing the hook (24) at the end of 2).
In the present invention, the cord is made of polyvinyl chloride (PVC) and the base is made of closed cell foam sponge (EVA foam).
In FIG. 2, a reinforcing member (4) made of polycarbonate (PC), polypropylene (PP), ABS resin or metal which is harder than closed-cell foamed sponge (EVA foam) is used. The relationship of further fixing the three hooks (24) with the three hook fixing holes (34) of the base (3) is shown. The reinforcing member (4) includes a reinforcing member main body (41) and a reinforcing member lid (42). Details will be described with reference to FIGS.

FIG. 3 illustrates the case where the ridge (24) at the end of the umbilical cord (2) in FIG. 2 is inserted into the table (3), and the ridge (24) at the end of the umbilical cord (2) is extracted from the table (3). Is an explanation of when
In the figure, (3-1) indicates that the end of the umbilical cord (2) is a "T" -shaped end face, and a long heel (24) is twisted vertically along the neck (25) to bring the base (3) It is the figure which showed the mode at the time of inserting in the scissors insertion hole (33).
The cord (2) of the present invention is manufactured by molding a soft resin such as polyvinyl chloride (PVC), and the ridge (24) at the end of the cord (2) can be bent as shown. As a result, the end of the umbilical cord (2) can be temporarily deformed into a vertically long shape, and the heel (24) can be easily inserted into the heel insertion hole (33) of the table (3) with the help of a human hand. Is possible. The cage (24) once inserted is returned to the original “T” shape in the cage fixing hole (34) provided continuously to the cage insertion hole (33) of the base. (2) can be fixed to the base (3).
Conventional foot sandals such as flip flops have a circular shape on the end face of the heel (24) in the present application, and a small hole with a strong force using a jig such as a dedicated umbilical cord insertion tool. The cord is put on the table by passing the candy in a stroke. The circular heel is finished into footwear with a chin that does not easily pass through a small hole (the heel insertion hole referred to in the present application) because it does not easily pass through. With this conventional circular fold, even if the heel is temporarily twisted by molding with a soft resin such as polyvinyl chloride (PVC) as in the case of the present application, the round fold can be twisted in any direction. Because of the same diameter, it is impossible to temporarily elongate the end of the umbilical cord with respect to the heel insertion opening as in the present application.
By preparing the bag (24) of the present application in a long shape, the diameter of the conventional bag is difficult to remove in the longitudinal direction, and the situation in which the bag can easily pass through the hole in the short direction is ensured. Twist the heel (24) at the end of (2) in the longitudinal direction as shown in (3-1) and temporarily narrow the end of the umbilical cord (2) along the neck (25), It is possible to facilitate insertion into (33). Also, as described later in (3-2), even when the cord (2) is pulled out of the base (3), it is temporarily deformed into a “f” shape like the bag (24) of the present application. Is a situation that cannot be obtained with the conventional round heel, and by making the heel (24) long, the umbilical cord (2) can be inserted into the base (3) with bare hands and with bare hands Pulling out becomes feasible.
Here, the material of the heel (24) is described with polyvinyl chloride (PVC) from the end of the umbilical cord (2), but the ridge (24) is deformed by twisting the end of the umbilical cord (2). Can be inserted into the heel insertion hole (33) of the pedestal (3) and then returned to its original shape. No.

(3-2) of FIG. 3 is a diagram showing a state in which the ridge (24) of the inserted cord (2) is pulled out from the table (3).
The member of the ridge (24) of the cord (2) is made of polyvinyl chloride (PVC), and the base (3) is a somewhat hard member like the closed cell foam sponge (EVA), but also retains cushioning properties, Locally, it is made of a flexible member that expands the hole moderately when pressed with a finger. Therefore, even with general human power, the cord (34) from the heel fixing hole (34) toward the heel insertion hole (33) By pulling 2), it is possible to temporarily deform the heel (24) into a “f” shape, and the heel insertion hole (33) of the base (3) can also be temporarily removed by the pulling force of the heel. The hole is widened by being pushed to the side, and the heel (24) can be pulled out from the heel insertion hole (33) with the force of a bare hand.
In other words, the diameter of the heel insertion hole (33) of the pedestal (3) (in consideration of the diameter of the hole due to the cushioning property of the pedestal) passes through the size when the ridge (24) is deformed into a "F" shape. Select the size of the ridge (24) of the chin cord (2) and the selection of the pedestal (3), and the diameter of the heel insertion hole (33) of the pedestal (3) By determining the dimensions of the heel (24), the umbilical cord (2) can be pulled out of the table (3) with bare hands.
For example, if the diameter of the heel insertion hole (33) of the base (3) is (L1) and the heel insertion hole widens (+ α) due to the softness of the member of the base (3), The diameter of the eaves insertion hole (33) when removing is temporarily (L1 + α). As for the ridge (24) of the umbilical cord (2), when the ridge is pulled out with the bare hand of the person, when the heel is deformed into a “f” shape and passes through the heel insertion hole (33), By setting the diagonal dimension to (L1 + α), it is possible to pull out the ridge (24) of the cord (2) from the table (3).
In Example 1, the entire cord is formed by molding with polyvinyl chloride (PVC), and the base (3) realizes this by opening the heel insertion hole (33) in the closed cell foam sponge (EVA). The diameter of the eaves fixing hole (34) is larger than the length of the diagonal line in the original state in which the elongate eaves (24) are not deformed into a “f” shape, and the front of the base (3) in FIG. The kite (31) and the rear kite (32) are constituted.

In the above description, we have explained how the umbilical cord (2) can be inserted into and removed from the platform (3) with general human power. It is preferable to further reinforce the fixing so as not to accidentally disengage from 3). For this purpose, after the umbilical cord (2) is inserted into the platform (3) using the reinforcing member (4) described in FIG. 2, the ridge (24) of the umbilical cord (2) is mounted on the platform (3) with the reinforcing member (4). There is a need for a device to securely fix the rod in the rod fixing hole (34) of 3). For this purpose, a reinforcing member (4) is prepared, and an adjusting member is proposed that can adjust the length of the chord (2) appearing on the front side of the table (3) according to the shape and size of the user's foot.
FIG. 4 is a perspective view of the footwear (1) with a nose using the reinforcing member (4) in the heel fixing hole (34) of the base (3), and FIG. 5 is a perspective view of the reinforcing member (4). It is the figure explaining how to use, and the figure explaining the adjustment member (5) which adjusts the length of a chord (2) further.

The reinforcing member (4) in Example 1 is made of a member such as polycarbonate (PC), polypropylene (PP), ABS resin or metal which is harder than the closed cell foam sponge (EVA) which is a member of the base (3). The ridge (24) at the end of the umbilical cord (2) after being inserted into the pedestal (3) is securely fixed, and reinforced and fixed so that the lanyard is not inadvertently detached from the pedestal (3). Objective.
Reinforcement and fixation here means to reinforce so that the heel (24) at the end of the umbilical cord (2) is not largely separated in the heel fixing hole (34) of the base (3). As described in (3-2), pulling out the collar (24) from the collar insertion hole (33) by deforming the collar (24) into the shape of "f" by pulling the cord (2). However, as will be described later, the reinforcing member (4) is reinforced so that the cord (2) cannot be detached from the base (3) by preventing the collar (24) from being deformed into a “f” shape. To fix.
The adjustment member (5) of Example 1 is a hard solid material such as synthetic rubber, natural rubber, metal, etc., and is made by processing a member having a predetermined thickness. This is a member for adjusting the depth position for fixing the flange (24), how much the end flange (24) is submerged and fixed in the anchor fixing hole (34) of the base (3).
As a supplement, the reinforcing member (4) and the adjusting member (5) of Example 1 are made of the above-described members. However, for the purpose of the reinforcing member, the hooks (24) are formed in the hook fixing holes (34) of the base (3). If it is a member that can adjust the position of the collar (2) at the end of the cord (2) as an adjustment member within the collar fixing hole (34) of the base, it can be described above. Regardless of the name of each member.

FIG. 4 is a view of the footwear (1) with the umbilical cord of Example 1 as viewed from the back, and the heel (24) of the umbilical cord (2) inserted into the front heel (31) of the table is used as the reinforcing member (4). The incorporated figure is shown. Also, in the rear right heel (32), the state of the heel (32) in which the ridge (24) of the cord (2) is already attached to the reinforcement member (4) and the reinforcement member lid (42) is visible is shown. The hind limb (32) in front of the right hand shows the hind limb (32) in a state where the cord (2) is not yet inserted and the reinforcing member is not loaded.
More specifically, the ridge (24) of the umbilical cord (2) inserted into the heel fixing hole (34) of the front heel (31) of the base shown in FIG. 4 is the reinforcement member main body (41) of the reinforcement member (4). ) Is inserted from the heel insertion opening (46), and the heel (24) is arranged in the heel installation section (47) so that the space of the heel insertion opening (46) straddles the neck (25) of the cord (2). . Then, by covering from above with the reinforcing member lid (42), the heel (24) is enclosed so that the end of the umbilical cord (2) has the original “T” shape, and the heel fixing hole (34) The reinforcing member (4) is housed inside.
The rear heel (32) in the right back of FIG. 4 houses the ridge (24) of the cord (2) in the reinforcement member (4), and the reinforcement member main body (41) with the reinforcement member lid (42). A state is shown in which the reinforcing member (4) has been accommodated in the cover fixing hole (34). The rear heel (32) in front of the right hand is still in a state before the ridge (24) of the cord (2) can be inserted, and the heel fixing hole (34) of the posterior heel (32) is visible from the back of the table. Indicates the state.

Next, the structure of the reinforcing member (4) will be described with reference to (5-1) and (5-2) in FIG. 5, and the reinforcing member (4) will be connected to the reinforcing member (4) with reference to (5-3) and (5-4). A description will be given of wearing the bag (24). Further, in (5-5) and (5-6), the adjustment member (5) for adjusting the length of the umbilical cord inserted between the reinforcing member (4) and the base will be described.
First, the configuration of the reinforcing member (4) will be described in (5-1). The reinforcing member (4) includes a reinforcing member main body (41) and a reinforcing member lid (42). The caulking protrusion (43) is passed through the caulking hole (44) of the reinforcing member lid (42), and the leading end of the caulking protrusion (43) is crushed from above the caulking hole (44) of the reinforcing member lid (42). Thus, the reinforcing member lid (42) is integrated with the reinforcing member main body (41) so as to be rotatable. In (5-1), the reinforcing member main body (41) and the reinforcing member lid (42) are connected by caulking, but there is no problem even if they are integrated by other methods such as screwing, as shown in FIG. The reinforcing member (4) can be prepared by integrally molding the main body and the lid.
Next, (5-2) is a diagram in which the reinforcing member (4) of (5-1) is turned over, and a fixing claw (45) is provided on the back of the reinforcing member lid (42) integrated so as to be rotatable. The reinforcing member lid (42) is provided by providing a space between the fixing claws (45) with a narrow gap slightly smaller than the width of the heel insertion opening (46) which is a horseshoe-shaped opening of the reinforcing member body (41). ) Is rotated so as to overlap the reinforcing member main body (41), the fixing claw (45) is caught in the space of the flange insertion port (46) and the reinforcing member lid (42) is positioned at a predetermined position of the reinforcing member main body (41). A state of being fixed to (5-2) is illustrated.

Next, in (5-3) and (5-4), description will be given of attaching the ridge (24) at the end of the cord to the reinforcing member (4). As shown in (5-3), the reinforcing member main body ( 41) is provided with a heel insertion port (46) and a heel installation portion (47), and the ridge (24) at the end of the umbilical cord is connected to the reinforcing member main body (41) with respect to the heel insertion port (46). Inserting from the side of the reinforcing member main body (41) using the horseshoe-shaped opening, installing the snare ridge (24) in the heel installing portion (47), and reinforcing member with the reinforcing member lid (42) from above By covering the main body (41), the snare ridge (24) is prevented from being detached from the reinforcing member (4). After installing the collar (24) on the reinforcing member (4), as explained in FIG. 4 above, in the collar fixing hole (34) of the front collar (31) or the rear collar (32) of the base (3). The reinforcing member (4) integrated with the cord is housed.
Since the heel (24) installed in the heel installation section (47) is covered with the reinforcing member lid (42) while maintaining the "T" shape which is the original shape, the above-described figure (3-2) ), There is no space in which the heel (24) changes to the shape of the “he” in the space of the heel fixing hole (34). Therefore, even if the cord (2) is pulled from the table (3) by human power, it is surrounded by the reinforcing member main body (41) and the reinforcing member lid (42), and the heel ( 24) will maintain the “T” shape and will reinforce the fixation of the umbilical cord (2) to the platform (3). (5-3) is a view showing a state before the flange (24) is installed on the reinforcing member (4), and (5-4) is after the flange (24) is installed on the reinforcing member (4). The state is illustrated.
Here, regarding the diameter of the reinforcing member (4) and the diameter of the flange fixing hole (34), the diameter of the flange fixing hole (34) is slightly larger than the diameter of the reinforcing member (4), and the cushioning property of the base (3) It is preferable to design it with a clearance that allows it to be mounted and held. In addition, although the reinforcement member (4) of Example 1 is manufactured with members, such as a polycarbonate (PC), a polypropylene (PP), an ABS resin, and a metal, if it is a member which can obtain the objective of a reinforcement member (4), There is no problem with other members.

Next, the adjustment member (5) will be described in (5-5) and (5-6). The adjustment member (5) is the same as the reinforcement member main body (41) in the space portion of the cord (2). When it is inserted so as to straddle the neck (25) and the reinforcing member (4) is loaded into the collar fixing hole (34) of the base (3), it is sandwiched between the base (3) and the reinforcing member (4). use.
As shown by (5-5), the adjusting member (5) inserted under the reinforcing member (4) can be used even after the ridge (24) of the cord (2) is stored in the reinforcing member (4). There is an opening so that it can be inserted into the neck portion (25), and any number of plates can be inserted between the base (3) and the reinforcing member (4). ).
(5-6) shows a state in which two adjusting members (5) are inserted under the reinforcing member (4). For example, if the thickness of the adjusting member (5) is 1 mm, 2 By adding the sheet adjustment member (5), the ridge adjustment width (51) obtained by adding 2 mm to the reinforcing member (4) is secured.
This means that the foot (24) of the cord (2) can be inserted 2mm deep into the platform (3) of the footwear (1) with the cord, and the cord (2) that appears on the front side of the platform (3) Can be shortened by 2 mm.

Since there are three heels in which the heel (24) can be inserted into the footwear (1) with a umbilical cord, the fixing depth of the heel (24) at the end of the umbilical cord (2) is set to this adjustment member ( Since it can be arbitrarily adjusted according to the number of items 5), the user can freely adjust the length of the cord (2).
Each person's foot has the same size as the foot, but the height of the back of the foot also varies, and even a single foot has subtle size differences and deformations on the left and right, so buy footwear. Some people want a pair of shoes with different sizes on the left and right, and other people use different ways to tighten the laces that tighten the width of the athletic shoes.
In the present invention, since the length can be adjusted by using the adjustment member (5) at each end when fixing the cord (2), the length of the cord can be different between the right foot and the left foot. It is also possible to adjust the length (22) of one umbilical cord (2) to a different length between the left and right rear limbs (32). As a result, the length of the umbilical cord (2) and the balance of the feeling of close contact with the skin can be finely adjusted according to personal preferences so as to fit each person's foot.
Here, the adjusting member (5) of Example 1 is a hard solid material such as synthetic rubber, natural rubber, metal, etc., and is made by processing a member having a predetermined thickness (for example, 1 mm thick). If the purpose can be obtained, there is no particular problem with other members. With respect to the nose cord adjustment width (51), the thickness of the portion corresponding to the nose cord adjustment width (51) indicated by the so-called (5-5) thickness of the reinforcing member main body (41) under the heel installation portion (47). Even when reinforcing members (4) having different thicknesses are prepared, it is possible to achieve the same purpose in adjusting the length of the nose.

FIG. 6 shows a state in which the reinforcing member is molded as an integral type without dividing it into a main body and a lid.
The reinforcing member (4) described in the explanation of FIG. 5 is composed of a reinforcing member main body (41) and a reinforcing member lid (42). When the ridge (24) is installed on the reinforcing member main body (41), the reinforcing member (4) is reinforced. The member lid (42) is rotated to open the top of the reinforcing member main body (41), and the neck portion (25) of the cord (2) is inserted from the opening of the heel insertion port (46), so that the heel installation portion (47) The trough (24) was installed so as to drop into the groove-shaped gap, and the stiffening member lid (42) was rotated so as to cover the trough (24) from four directions and stored in the reinforcing member (4).
On the other hand, the reinforcing member in FIG. 6 has a structure in which the main body and the lid are integrated. In the figure, the reinforcing member lid (42) is labeled so as to be distinguished from the conventional separation type, but it rotates. There is no need for the structure so that the bag (24) can be easily installed.
(6-1) is before the installation of the cage (24), and (6-2) is after the installation. Specifically, the reinforcing member lid (42) described in FIG. A reinforcing member main body (41) having an insertion port (46) and a hook installation portion (47), that is, a reinforcing member (4). As shown in (6-1), it is inserted from the side of the bowl (24) through the opening of the bowl insertion port (46), and the bowl (24) slides sideways as shown in (6-2). If it is installed so as to be in contact with the back, the heel (24) is surrounded by the three sides of the top and bottom and one side, so that the T-shape of the heel (24) is maintained, and in the state of (6-2) as shown in FIG. By storing in the heel fixing hole (34) of the base (3), the fixation of the cord (2) to the base (3) is reinforced.

As described above with reference to FIGS. 2 to 6, the first embodiment twists the heel (24) at the end of the umbilical cord (2) and twists it into the heel insertion hole (33) of the pedestal (3) with bare hands. 2) is inserted, and the ridge (24) enters the heel fixing hole (34) and returns to the original shape of the heel (24), thereby fixing the cord (2) to the base (3). ) Bends by the force that pulls out the umbilical cord (2), so that it is possible to remove the nasal cord from the table with the power of bare hands, so that the user can easily replace the umbilical cord (2).
In order to further secure the umbilical cord (2), it can be reinforced using the reinforcing member (4).
Since the length of the umbilical cord can be arbitrarily adjusted by using the adjusting member (5), the user can select an optimal color pattern according to the situation of wearing the knitted footwear (1) of the first embodiment. You can choose the combination of the umbilical cord (2) and the optimal color and shape (3) by yourself, and you can easily change the umbilical cord and adjust the length of the umbilical cord (2) freely. It becomes possible to obtain a new footwear with a nose (1) that is more convenient than footwear with a nose.

FIG. 7 illustrates a state in which the conventional cord and the present cord can be inserted, and details of the comparison based on the measurement data will be described.
There are two types of footwear with umbilical cords: Japanese lanyard made of cloth, etc., and velvet sandals made of vinyl chloride. In addition, there are two types of bases: ancient Japanese wooden bases and bases made of materials such as rubber and EVA.
This article explains the current situation of the force when inserting the umbilical cord into the pedestal and the force when removing the lanyard from the pedestal for footwear with a umbilical cord made of vinyl chloride and EVA pedestal. The measurement data of the force when inserting the cord on the table and the force when pulling the cord from the table according to the invention will be described to explain the difference between the conventional product and the present application.
First, a description of a chord generally used for flip flops, etc., as shown in (7-1), the shape of the collar (24) at the end of the chord is a circular shape, and the diameter of the neck (25) of the chord is The diameter of the circular ridge (24) is 13 to 15 mm, and the larger one is 19 mm, and the thickness of the ridge is about 5 mm in most cases. In the figure, the neck (25) is drawn in a square shape in cross section, but the shape of the present application and the conventional product has squares and circles and has no particular effect on measurement, so there are many in the conventional product regardless of the drawn shape. The neck has data with a round cord.
In addition, the circular shape of the heel has a situation where the front heel is slightly larger than the back heel because force is applied to the front of the footwear during walking.
When this ridge (24) is inserted into a hole drilled into the base, the heel insertion hole (33) referred to in the present application, and the ridge (24) fits into the heel fixing hole (34) connected thereto, the ridge (24) becomes It becomes difficult to pull out into the small heel insertion hole (33), and the thong is fixed to the table.

Next, a description will be given of the shape of the ridge that is inserted in the conventional pedestal such as EVA, and the shape of the ridge is rounded. The diameter of the hole on the front side of the base is a hole equivalent to 7 to 8 mm, which is the diameter of the neck leading to the ridge at the end of the inserted cord, and the diameter of the hole on the back side of the base is compatible A hole having a diameter of 13 to 15 mm, which is a circle, and a large one having a diameter of 19 mm is drilled. And these holes are provided in a shape like a “convex” shape in the cross section of the space, leaving a predetermined thickness on the upper part of the table so that each hook can be held in the table in the middle of the table .
That is, as shown in (7-1), the space shape is perforated with two large and small holes, and the diameter of the small hole above, that is, the diameter of the heel insertion hole (33) is from 7 which is the diameter of the neck of the nose. It is equivalent to 8mm, and the diameter of the lower large hole, that is, the diameter of the heel fixing hole (34) is 13 to 15mm which is the diameter of the ridge of the umbilical cord, and the larger one is 19mm. The ridge (24) is caught on the surface of the step where the diameter of the large and small holes of the ridge with the convex shape of the space changes, so that the thong does not come off the base, but the depth of the heel fixing hole (34) Designed and manufactured so that at least the thickness of the heel (24) fits, the neck (25) fits in the heel insertion hole (33), and the length of the nose is an appropriate length on the upper surface of the table, The reality is that it is on the market as a product.
In this measurement, the conventional sandal sandals were used as the measurement material. However, it is generally accepted that the snagging force of the beach sandals is 100 Newtons (10 kg) or more in the footwear industry. The research organization is OK at 130 Newton (13 kg).
Here, the relationship between kg and Newton is 1 kg = 9.80665 Newton, and it is difficult to understand in Newton units with the tensile strength measuring instrument. Therefore, in the following explanation, generally used kg units are listed in () for reference. And explain.
In addition, the hardness meter used for this measurement is a durometer hardness meter of ASKER “Polymer Keiki Co., Ltd.”, and the tensile strength measuring device is a SHIMADZU autograph AGS-X5KN.

Now, the conditions at the time of measurement will be explained first. The beach sandals used to measure the force when inserting the umbilical cord with footwear with conventional umbilical cord and the force when detaching it are the material of the base is 55 degrees hardness Using EVA, the diameter of the perforated hole of the scissors is 8.5 mm, and the thickness from the step of the large and small holes of the scissors to the surface of the table is 9 mm. That is, as shown by (7-1), the diameter of the scissors insertion hole (33) is 8.5 mm and the depth is 9 mm.
The material of the umbilical cord was vinyl chloride at an altitude of 72 degrees, and the forerunner of the umbilical cord. The neck (25) had a diameter of 7 mm, a heel diameter of 19 mm, and a heel thickness of 5 mm. In this condition, the power to insert the conventional cord on the table is
91.4502 Newton (9.332533 kg).
As a test method, just as with a conventional umbilical cord, the ridge at the end of the umbilical cord is pinched with the tip of a dedicated insertion tool, and the state of the end of the inserted insertion tool is measured with a tensile strength measuring instrument. did.
As generally understood, since the diameter of the perforation hole of the base collar is 8.5 mm, it is not easy to insert the diameter of 19 mm of the collar here. For this reason, the flexibility of EVA, which is the material of the table, is instantaneously forced by mechanical force with a chin cord between the tip of a jig called an insertion tool that passes through the hole from the bottom of the table. The current manufacturing technology in the industry is to pull in and use the cord. In this measurement, as shown in (7-2), hold the heel (24) firmly with the tip of the insertion tool that passed through the hole from the bottom of the base, and insert the heel (24). The tool has a shape in which the tip at the top expands like a tulip flower, and the bottom of the tool is narrower than that and smaller than the diameter of the eyelid insertion hole (33). The pulling force of about 91 Newton (9Kg) is momentarily applied, and the tulip-shaped tip shape of the insertion tool widens the heel insertion hole (33) of the EVA base to the side. Pass the heel (24) at a stretch, and when the heel (24) passes through the base, the tip of the insertion tool opens like an umbrella and comes off the heel (24), and the thong is pulled back to the upper side of the base and used as footwear. As a result, the heel (24) is placed in the heel fixing hole (34) and the nose is inserted into the platform.
In addition, as for the force when pulling the umbilical cord from the conventional table, it was examined whether the inserted nasal cord was pulled out from above, but in the measurement, the nasal cord was cut off at about 241 Newton (25 kg). This measured value is larger than 130 Newton (13 kg), which is the missing value of the industry association, and the result is that the material of the nose made of vinyl chloride is weaker and is cut off.

Next, the measurement conditions for the case where the cord of the present invention is inserted into the table and the case where the cord is pulled out are the same as those in the conventional product, the neck diameter is 7 mm, the thickness of the collar is 5 mm, The diameter of the 19 mm circular ridge was cut at both ends to obtain a long ridge having a length of 19 mm and a width of 7 mm. In the same way as the test of the above-mentioned conventional product, the diameter of the punch insertion hole is 8.5 mm and the depth is 9 mm.
The force when inserting the cord on the table is 43.5956 Newton (4.44551 kg),
The force for pulling the thong from the table was 55.4427 Newton (5.665358 kg).
The measurement when inserting the cord was made by making a small hole at the tip of the heel and pulling it through the string and pulling it from the back of the table with a measuring instrument.
From this measurement result, in the case of the conventional circular ridge, it took about 91 Newton (9 kg) by mechanical force using the insertion tool, but in the case of the long fold, it was half of 44 Newton (4 kg). It was confirmed as a numerical value that it was inserted.
In addition, when pulling out the cocoon from the stand, the conventional circular cocoon had not yet reached the point where the vinyl chloride thong was cut off and the cocoon was pulled out. The shape of can easily be deformed into a “he” shape, and it was proved by numerical results that it could be pulled out with a force of 55 Newton (6 kg).

Comparing the measured values, the force when inserting the cord of a conventional product is 241 Newton (25 Kg) when pulling out with 91 Newton (9 Kg), and the force when inserting according to the present invention is 44 Newton (4 Kg) When it is pulled out, it is 55 Newton (6Kg), and the cord of the present application can be accepted when it is inserted with less than half the force of the conventional product and with a force not much different from that.
In the light of the purpose of the present application of inserting the umbilical cord into the table with bare hands, when looking at the measured value and the detachment method of the umbilical cord, as shown in (7-1), in the heel insertion hole (33) with a diameter of 8.5 mm It is difficult to manually insert a heel (24) having a circular diameter of 19 mm, and the force of pinching of the insertion tool, the force of pulling out the machine as in (7-2), and above all, the tulip shape In order not to combine the powerful force and the mechanism that is inserted while pushing the heel insertion hole (33) from the thin side to the thick side in the shape, 8.5mm 鍔 insertion of the conventional circular 19mm 鍔 (24) Inserting into the hole (33) is impossible with the operation and force of bare hands.
The thong of the present invention has a long end face of the heel (24) as shown in (7-3), and the measurement results are obtained by measuring with a long ridge (24) having a length of 19 mm, a width of 7 mm, and a thickness of 5 mm. Thus, the size when passing the scissors insertion hole (33) by twisting the scissors (24) vertically so as to follow the neck (25) is reduced, so the force of the person's bare hands of 44 Newton (4Kg) A string that can be easily inserted is realized.
With regard to the force to pull the umbilical cord, the heel (24) is curved so that it can be pulled out from the heel insertion hole (33) with the force of a human hand of 55 Newton (6Kg). Therefore, it is the present invention that the ribs (24) are prevented from being bent to reinforce the fixation of the umbilical cord, and the length of the umbilical cord can be adjusted by enclosing it with a reinforcing member.
In general, the pushing force or pulling force with a human hand is a value of around 60 Newtons, as indicated by the upper limb operation force of the human characteristics database of the Incorporated Administrative Agency and Product Evaluation Technology Infrastructure.
Therefore, the value of the force for inserting the long cocoon of the present application into the table and the force for pulling the string from the table are values equivalent to the force of a human hand, and the value of the cord can be adjusted without using a jig. It can be proved from the measurement result that it can be inserted and removed.

FIG. 8 is a perspective view of the footwear with umbilical cord of Example 2, the footwear with nasal cord (1) is composed of a umbilical cord (2) and a table (3), and the umbilical cord (2) is the nasal cord of the present invention described in FIG. In other words, a long ridge (24) is provided at the ends of the umbilical forehead (21) and the two backs (23).
As can be seen from FIG. 8, in the second embodiment, the shapes of the front heel (31) and the rear heel (32) provided on the table (3) are different from those in the first embodiment. In the first embodiment (see FIG. 2), the front kite (31) and the rear kite (32) are each composed of a round kite insertion hole (33) and a kite fixing hole (34). The insertion hole (33) is an elongated hole that matches the shape of the chin cord (24) and penetrates from the top to the bottom of the table (3). A long space corresponding to the shape of the ridge (24) is provided at a predetermined depth from the back surface of 3) and intersecting with the ridge insertion hole (33) penetrating through 90 degrees. When viewed from the back surface of the base (3), the hook insertion hole (33) and the hook fixing hole (34) intersect each other by 90 degrees so that a hole in the shape of a cross is provided partway through the base.
Here, the predetermined depth from the back surface of the pedestal (3) means that the thickness of the ridge (24) is determined after securing the thickness of the pedestal so that the ridges (24) of the cord on the pedestal are not removed from the pedestal. It is the depth of the collar fixing hole (34) which fits.
8 is prepared in a state that is long in the lateral direction with respect to the longitudinal direction of the cord (2), the rod insertion hole (33) of the corresponding base (3) is prepared. ) Is provided in an elongated shape equally in the longitudinal direction of the table (3). After the ridge (24) at the end of the nose is inserted, the heel fixing hole (34), which is a hole for fixing the ridge (24), intersects the longitudinal direction of the table by 90 degrees, Like the ridge (24), it is provided in a long horizontal direction.
In this way, first, twist the end of the umbilical cord, insert the heel (24) into the heel insertion hole (33) penetrating the platform (3) in a direction different from the direction of the nasal cord, and then The twist of the end is returned to the original position, and the heel (24) is placed in the heel fixing hole (34) drilled at a predetermined depth in the pedestal (3) in the original heel (24) direction. It becomes possible to insert and fix the cord (2) to 3).

In FIG. 9, the state at the time of inserting and extracting a cord to this stand (3) is demonstrated concretely.
First, when inserting the umbilical cord (21) into the platform (3), twist the umbilical cord (2) 90 degrees relative to the platform (3) as shown in (9-1). Then, the heel (24) at the end of the umbilical cord (21) is aligned and inserted from above into the heel insertion hole (33) penetrating the front heel (31) of the table. And after penetrating until the heel (24) is exposed on the back side of the base (3), the umbilical cord (2) is returned to the original direction and is provided at the lower part of the front heel (31) of the base (3). By storing the heel (24) in the heel fixing hole (34), the front (21) of the umbilical cord (2) is inserted and fixed to the base (3).
Next, in (9-2), the method of inserting the back into the base will be explained. Twist the end of the back (23) and insert it into the back insertion hole (33) passing through the back back (32) of the base. Align the direction of the heel (24) at the end of the umbilical cord and insert it from above. Then, after penetrating the back of the base (3) until the ridge (24) is exposed, twist the end of the nose back to the original orientation so that the nose (2) is in the correct orientation on the base (3). By placing the ridges (24) following the umbilical cord in the heel fixing holes (34) of the posterior heel (32) provided at an angle different from the heel insertion hole (33) by 90 degrees, (2) The back (23) is inserted into the base (3) and fixed.
Next, the operation when the cord (2) is extracted from the table (3) will be described. Each of the ends of the cord (2) to be extracted, such as the front and back, is pushed from the front side to the back side of the table (3). Then, the heel (24) contained in the heel fixing hole (34) is exposed to the outside of the base (3), and the direction of the heel fixing hole (34) is rotated by rotating the direction of the end of the nose (2) by 90 degrees. The end of the umbilical cord (2) can be extracted from the platform (3) by pulling up the heel (24) which is the same with the direction of the heel insertion hole (33).
If this operation is performed on the three ridges (24) of the umbilical cord (2), the ridge (24) at the front (21) and the posterior (23) of the end of the nasal cord (2) is placed on the platform (3). Easy to remove from.
As described above, the cord (2) of the present invention can be inserted into and removed from the table (3) by a simple operation, so that the user can use the cord (2) and the table (3) with different designs as needed. Can be easily replaced.

In the second embodiment, the elongated direction of the heel insertion hole (33) and the heel fixing hole (34) of the base (3) was described in the description of FIG. 9, but each end of the umbilical cord (2) is twisted and inserted. Finally, when the heel (24) is stored in the heel fixing hole (34), it is sufficient that the umbilical cord (2) is fixed to the base (3) in the correct orientation as shown in FIG. When the heel (24) is provided in the longitudinally long direction as in the longitudinal direction of the umbilical cord (2) rather than in the horizontal direction, the heel fixing hole (34) of the base (3) If it is provided at a predetermined depth so as to be in the same direction as (24), and the heel insertion hole (33) that intersects and extends through the base (3) in a direction rotated by 90 degrees, the same operation is performed. The umbilical cord (2) is inserted into the table (3) and fixed.
The angle at which the heel insertion hole (33) and the heel fixing hole (34) intersect is not limited to 90 degrees. If the end of the umbilical cord (2) is hard and firm and the heel (24) does not move easily from the heel fixing hole (34) to the heel insertion hole (33), the heel insertion hole (33) and the heel fixation Even if the angle of the hole (34) is 10 degrees, for example, when using the footwear (1) with the nose of the present application, if the heel (24) does not move from the heel fixing hole (34) to the heel insertion hole (33), There is no problem even if the angle is minimal.
In addition, when the shape of the chin cord (24) is a shape other than the long shape, the shape of the heel insertion hole (33) and the heel fixing hole (34) of the base (3) is the shape of the chin cord (24). For example, if a heart-shaped heel (24) is provided vertically at the end of the umbilical cord (2), the heel fixing hole (34) provided in the base (3) is the same heart as the heel (24). The mold is provided in the vertical direction, but if the heel insertion hole (33) is not in the vertical direction, it may be rotated horizontally by 90 degrees or by twisting the end of the nose (2), such as 10 degrees to 80 degrees, and the table (3) There is no problem if the hook (24) can be fixed to the hook fixing hole (34).

As an example, even if a pin hole is made near the tip of the neck (25) at the end of the cord (2), a hard metal rod is inserted into the hole, and the cross-section is like a “middle” character in Chinese characters. Becomes 鍔 (24). Although not shown, when the collar (24) is prepared in the shape of the "middle" character, the collar insertion hole (33) has a round hole through which the neck (25) passes and a notch through which the metal rod passes. A through hole may be provided in the table in such a manner. In FIG. 8 and FIG. 9, the eaves insertion hole (33) provided in the table (3) is drawn as a long square, but in an actual machining process, it is easier and more efficient to make a round hole than the long square.
Even if the footwear with nose (1) is a hard member such as wood, a hole is inserted in the shape of a “medium” by making a round cut and making a straight notch that penetrates in one direction of the circumference. , The part where the umbilical cord (2) appears on the surface of the base (3) will expose the circular neck (25) from the general round hole, and the thin straight notch is inconspicuous and the footwear with the chin The appearance of (1) is improved.
Then, the 中 (24) in the shape of “middle” is rotated after passing through the 鍔 insertion hole (33) in the shape of “middle”, and a straight cut into which the metal bar is accommodated is provided at an arbitrary depth. It is possible to fix the umbilical cord (2) by placing a metal rod in the heel fixing hole (34), which is used only by itself, and the direction of the straight cut is the angle and angle of the piercing hole (33) that penetrates As long as there is a shift, no problem will be caused by any angle such as 10 to 90 degrees, and the metal rod will be accommodated so that the collar (24) can be accommodated in the collar fixing hole (34). It is possible to fix (2) to the base (3).

In FIG. 10, the details of the procedure for inserting the cord in Example 2 and the adjustment member (5) used in Example 2 will be described with reference to cross-sectional views. Although the method of inserting the cord in Example 2 has already been described with reference to FIG. 9, it is shown in an easy-to-understand manner in perspective and sectional views focusing on one ridge and one ridge (24).
Roughly speaking, (10-1), (10-2), (10-3), and (10-4) are situations in which a cord (24) can be inserted into one heel, such as a forehead or a back heel of a table. (10-5), (10-6), (10-7) and (10-8) are sectional views thereof. (10-9) is a perspective view for explaining the adjusting member (5) to be inserted onto the ridge (24) when the ridge (24) is exposed on the back side of the table. (10-10) (10-11) These are sectional drawings for demonstrating the condition using an adjustment member (5).
First, (10-1) illustrates the positional relationship between the heel insertion hole (33) and the heel fixing hole (34) provided in the base in a state before inserting the chin cord (24) into the heel. The eaves insertion hole (33) is a long, perforated hole that penetrates from the top surface to the bottom surface of the table, and its orientation is the direction of a “cross-shaped” rotated 90 degrees, with a predetermined depth from the bottom surface of the table. The fixing hole (34) is also provided with a long shape. As shown in the cross-sectional view of (10-5), the twisted ridge (24) before insertion can be seen in the narrow direction as well as the long narrow direction. On the other hand, the anchor fixing hole (34) has a structure in which the long longitudinal direction can be seen from the bottom surface at a predetermined depth.
(10-2) shows a state in which the ridge cord (24) is inserted and penetrated into the heel insertion hole (33). As shown in (10-6), the heel (24 ) Is in a state where the end of the umbilical cord is pushed in until it is exposed, and the direction of the inserted collar (24) is visible on the narrow side.
In (10-3), the neck (25) of the umbilical cord is rotated by 90 degrees by hand, and the heel (24) connected underneath is also rotated together. Like the cross-section (10-7), the heel (24) is in a situation where the long and long direction can be seen in the same manner as the heel fixing hole (34).
(10-4) is a state in which the heel (24) is housed in the heel fixing hole (34) by pulling up the nose from the state where the heel fixing hole (34) and the heel (24) are in the same direction, As shown in (10-8), the length of the umbilical cord appearing on the table is determined when the heel (24) is in contact with the level difference between the heel fixing hole (34) and the heel insertion hole (33). Then, the umbilical cord is inserted into the table and fixed.

From (10-9), the situation in which the adjustment member is used in the second embodiment is illustrated, the situation in which the adjustment member is inserted is explained with a perspective view, and the adjustment is made with the sectional views of (10-10) and (10-11). The effects of the members will be described.
First, (10-9) shows a state in which the “U” -shaped adjusting member (5) is prepared, and passes through the scissors insertion hole (33) from the bottom surface of the base (24). ) Is exposed, the adjustment member (5) is inserted onto the ridge (24) for use. In the figure, the central cavity of the adjustment member (5) straddles the neck (25) of the thong and the wall thickness on both sides overlaps on both sides of the heel (24) by drawing in a “U” shape. However, the shape of the adjustment member (5) is not limited to this shape as long as the adjustment effect described later in the cross-sectional view can be obtained. For example, the collar (25) separated by the neck (25) Even if two plate-like adjustment members (5) are inserted on both sides of 24), the same adjustment effect is achieved.
(10-10) is a cross-sectional view showing that two adjustment members (5) are inserted on the flange (24) in the flange fixing hole (34). A state in which one adjustment member (5) is inserted on the flange (24) in the fixing hole (34) is shown in a sectional view.
Here, if the thickness of the adjusting member (5) is 1 mm, in (10-10), the position at which the collar (24) is fixed in the collar fixing hole (34) is 1 mm + 1 mm and is about 2 mm thick. As a result, the length of the nose that appears on the upper surface of the table is shortened by 2 mm. When one adjustment member (5) is inserted as in (10-11), the heel (24) is fixed 1 mm deep, and the length of the nose appearing on the upper surface of the table can be shortened by 1 mm.
That is, the purpose and effect of the adjustment member (5) of the second embodiment are to realize the same function as the adjustment member (5) shown in FIGS. 5 (5-5) and (5-6) of the first embodiment. Also, in the second embodiment, as in the first embodiment, by adjusting the fixed depth of each heel (24) with each heel, the user himself / herself can easily become a thong that fits the user's foot. The length can be adjusted.

Although not shown, the shape of the reinforcing member (4) shown in FIG. 5 is different from that of the reinforcing member (4) shown in FIG. If a reinforcing member that can maintain a “T” shape is prepared with respect to the neck (25) and is reinforced so that it cannot be bent with a structure surrounding the thickness of the collar (24), the collar (24) can be easily Fixation can be reinforced in the heel fixing hole (34) so as not to slip out into the insertion hole (33).
In the first embodiment, the heel insertion hole (33) and the heel fixing hole (34) are disclosed as examples of the base (3) in consideration of cushioning properties such as closed cell foam sponge (EVA). The base (3) is a means for realizing the object of the present invention in consideration of a member having little or no cushioning property such as wooden. Further, considering the configuration of the cord (2) which is not flexible at the end of the cord (2), such as a Japanese cord, and is harder than a resin such as polyvinyl chloride (PVC), the cord as in Example 1 is considered. Even if you can't insert only the ridge (24) of (2), you can insert the ridge into the table by changing the direction of the ridge (24) by twisting the end of the ridge (2) Therefore, the second embodiment makes it possible to propose a footwear (1) with a nose that produces the same effect in the member of the nose (2) and the member of the base (3) that are difficult to realize in the first embodiment.

Thus, also in Example 2, as explained in FIGS. 8 to 10, the platform (3) is obtained by twisting the end of the nose (2) with the power of a human hand and adjusting the direction of the heel (24). The user can easily insert the cord (2) into the platform (3) by inserting the cord (2) into the rod insertion hole (33) of the kite and placing the kite (24) in the kite fixing hole (34). In order to secure the fixing, the reinforcing member (4) can be used to reinforce, and the adjustment member (5) can be used to arbitrarily increase the length of the cord. Therefore, the user can easily insert the cord (2) with the optimum color pattern into the platform (3) with the optimum color and shape with bare hands according to the situation where the user wears the footwear with the cord. At the same time, it is possible to freely adjust the length of the umbilical cord (2), so it is possible to wear it with a conventional umbilical cord. It is possible to get a more user-friendly new thong-out footwear.
