Description

footwear

The present invention belongs to footwear such as business shoes, casual shoes, and sandals, and particularly relates to a new type of footwear in which a foot is put in after the size of the mouth is determined in advance.

In general, footwear is made small, such as business shoes, sneakers, etc., and the shoe lace is untied when taking off, and loafers, slip-ons, etc. There are known ones that can be worn without using a lace, using a shoe spatula or pulling a tag attached to the buttock by hand.
In either case, you must bend when wearing it. This is a painful movement for the elderly. Also, if the mouth is large, it is difficult for the foot to stabilize in the footwear during walking.
Therefore, footwear having the following structure has been proposed as a footwear having a small mouth and can be worn without bending.
(1) Footwear provided with a mechanism for opening and closing the heel portion (see Document 1).
(2) Footwear in which stretchable portions are provided on the front and both sides of the shoe mouth, and a shoe-belt-like heel guide portion is provided on the rear portion of the shoe mouth (see Document 2).

JP 2011-234840 A Utility Model Registration No. 3153220

However, the technique (1) is not practical because the opening / closing mechanism has a complicated structure and is likely to fail, resulting in high manufacturing costs. In the technique (2), since the heel guide part protrudes above the rear part of the shoe mouth, it is difficult to put the foot into the footwear, and the degree of freedom of the ankle angle is greatly limited by the heel guide part after wearing. . In addition, since the wearing mouth can be expanded and contracted, the foot cannot be firmly held during walking.
An object of the present invention is to solve the above problems and to provide footwear that can be easily worn while standing, is easy to walk, and is difficult to take off.

In order to solve the above-mentioned problem, the invention according to claim 1 is provided with an upper that wraps a foot, and a mouth that can be adjusted in size and an instep covering portion that covers the back of the foot, and a front portion of the mouth. Is provided with an adjusting means for adjusting the size of the mouth, and on the back side of the upper covering portion, an elastic member that becomes an obstacle when the instep is inserted is provided so as to be stretchable in the thickness direction. In the heel part, a heel guide part for guiding the back side of the heel of the foot when worn is formed integrally with a reinforcing member provided on the heel part, and the height of the heel guide part is set to the height of the worn foot. The elastic member is compressed between the height from the back of the heel to the rear upper end of the rib and 70% of the height, and the instep of the foot pushed in from the mouth whose size is adjusted by the adjusting means. It is characterized by putting the foot inside the upper.

The invention according to claim 2 is characterized in that, in claim 1, the elastic member is formed integrally with the upper covering portion.

The invention according to claim 3 is characterized in that, in claim 1, an upper presser for pressing the upper of the foot is provided on the back side of the upper covering portion, and the elastic member is formed on the reverse side of the upper presser. To do.

The invention according to claim 4 is characterized in that, in claim 3, the upper presser is provided with a holding member for holding the shape of the upper presser.

The invention according to claim 5 is characterized in that, in

claim

3 or 4, the upper presser is attached so as to be held upward via a suspension member.

According to the first aspect of the present invention, when the footwear is put on, the size of the mouth is adjusted and fixed so that the elastic member presses the instep of the foot by the adjusting means. If the user puts his / her foot in the standing posture and enters from the mouth, the upper part hits the elastic member on the back side of the upper cover part and the heel hits the upper surface of the heel guide part. When the force is further applied to the foot and pushed in, the elastic member is compressed in the thickness direction and the foot can be pushed in. Since the elastic member is restored in the worn state, the instep is pressed and stably held in the footwear, and walking is easy.

踵 Since the heel guide part is formed integrally with the reinforcing member provided on the heel part, the heel guide part will not be deformed even if the foot is pushed in while pressing the back surface of the heel part.

During walking, when kicking the foot forward, the upper part of the foot is pushed up to compress the elastic member, but this compression is surface pressure, which is smaller than the compression force when putting the foot in, and the inside of the footwear The effect of expanding the space is poor. Therefore, the foot is stably held in the footwear and is difficult to remove.

In addition, since the height of the heel guide part is between the height from the back of the heel of the foot that has been worn to the rear upper end of the rib and 70% of this height, it is easy to wear the foot, Besides being able to hold the foot enough, the ankle can be bent freely, so walking is easy.

According to the invention of claim 2, since the elastic member is formed integrally with the upper covering portion, the structure becomes simple.

According to the invention of claim 3, the upper presser for pressing the upper of the foot is provided on the back side of the upper cover portion, and the elastic member is formed on the reverse side of the upper presser. Easy to hit the center. Therefore, the elastic member can be effectively compressed when putting it on.

In the invention according to claim 4, since the upper presser is provided with a holding member that holds the shape of the upper presser foot, the upper presser foot is not deformed by pressure and friction at the time of putting on, and smooth putting on is always ensured. The

According to the invention of claim 5, since the upper presser is mounted so as to be held upward via the suspension member, the elastic member does not sag when not in use and the mouth is not blocked. Smooth wearing can be performed.

(Embodiment 1)
1 and 2, reference numeral 1 denotes an upper, and 2 denotes a sole portion. The upper 1 is a portion that wraps the foot, and is made of a material such as chemical fiber, natural fiber, or synthetic leather. The upper part is provided with a mouth 3 and is formed so that the length before and after the mouth 3 is about half of the total length of the footwear.

In the front of the mouth 3, an instep covering portion 4 that covers the instep is formed. An adjustment opening 5 is continuously formed in front of the mouth 3 at the upper part of the upper cover 4. The size of the mouth 3 is determined by the width of the adjustment opening 5.

An upper belt 6 is provided in the upper 1 so as to cross the adjustment opening 5, one end of the upper belt 6 is fixed to one side of the upper cover portion 4 across the adjustment opening 5, and the other end is secured by a hook-and-loop fastener. It is detachably attached to the other side of the cover 4. The upper belt 6 is an adjusting means for adjusting the opening degree of the adjustment opening 5 within a certain range, and the size of the entire mouth 3 can be adjusted by the fixing position of the end of the upper belt 6. The upper belt 6 may be replaced with other members such as shoelaces.
By adjusting the width of the adjustment opening 5 with the upper belt 6, the size of the wearing mouth 3 is determined.

By the way, the toes bend when walking, but the instep does not bend, so it is preferable that the instep and the instep cover 4 move as much as possible. If the area of the upper cover 4 covering the upper is small, the unity between the upper and the upper cover 4 is lowered, and the foot is not stably held in the footwear. Preferably, the upper cover 4 covers 80% or more of the upper of the foot excluding the toes.

In this connection, it is preferable that the mouth 3 is fixed so as not to move. However, for example, the upper belt 6 may be made of a material having a small expansion / contraction force, and may be slightly expanded / contracted instead of being completely fixed.

Next, an elastic member 7 is disposed on the end portion of the upper cover portion 4 across the adjustment opening 5 and the back side in the vicinity thereof. The elastic member 7 is made of a material that can be expanded and contracted in the thickness direction, such as sponge, rubber, urethane, felt, and the like, and is disposed at a site that obstructs the wearing of the foot. That is, the rear end portion of the upper cover portion 4 constitutes the front portion of the mouth 3, and the foot can be put in from this portion, so that the end portion of the upper cover portion 4 and the back side in the vicinity thereof are It constitutes a part of the slip-in route. And the elastic member 7 is arrange | positioned so that it may protrude in the putting-in path | route.

The elastic member only needs to be able to expand and contract in the thickness direction, and is not limited to one in which an elastic material is formed thick. It is good also as a structure which can extend | stretch in the thickness direction as a whole by applying a rubber string on an inelastic material.

Next, a hard reinforcing member 9 made of synthetic resin or the like is provided in the inside of the heel part 8 provided at the rear end of the wear mouth 3 and is fixed to the sole part 2 in order to retain the shape of the heel part 8. . At the upper end of the reinforcing member 9, a heel guide portion 10 is provided. The heel guide portion 10 is formed integrally with the upper end portion of the reinforcing member 9 by covering and fixing the upper end of the reinforcing member 9 with the cloth material 11 or the like. The heel guide portion 10 may be formed integrally with the reinforcing member 9 and exposed to the upper portion of the heel portion 8. Further, the reinforcing member may be any member that reinforces the rear end portion of the mouthpiece 3 so as not to be deformed, and may be provided double inside and outside the heel portion 8. Therefore, as shown in FIG. 3, the heel guide portion 10 may also be configured to be provided on the external reinforcing member 12 provided on the outer surface of the heel portion 8. In addition, since the heel guide part 10 is rubbed strongly on the back surface of the foot, it is preferable to reinforce it with leather, a high-strength cloth material or the like.

好適 The preferred height of the heel guide varies depending on the size of the footwear. However, the size of footwear, regardless of its size, corresponds to the size of the foot of the person who wears it. Therefore, the height of the heel guide portion can be made to correspond to the height of the heel of the foot put on the footwear. Since there is a rib in the inside of the heel and the rib bulge in the rear part can be confirmed by touching with a hand, the height of the heel can be indicated by using the upper end position of the rear part of the heel.

Therefore, when actually wearing one size of footwear with different heights of the heel guide part, measure the height of the suitable heel guide part that is easy to put on and difficult to take off, and further, the measured value is the footwear I replaced it with the height of the cocoon. The same experiment was performed on other sizes of footwear.

As a result, as shown in FIG. 4, the height of the heel guide portion 10 that satisfies the above conditions is the height from the back surface of the heel 13 a of the foot 13 that is worn to the upper end of the rib bulge at the rear of the rib 14. It has been found that a height h between H1 and 70% of this height H2 is optimal. At a height that does not reach the height H2, the strength of the heel portion 8 is sufficient and easy to wear, but the heel tends to be easily removed when walking on a hurry. When the height exceeds the height H1, it is difficult to take off, but at the same time, it is difficult to put on the foot. However, the height dimension is related to whether the upper 1 is leather or fiber (whether it is easy to stretch), the thickness and elastic modulus of the elastic member 7, the difficulty of sliding the inner surface of the upper 1, and the like. A few percent above or below H1 or H2 is within the error range.

It should be noted that if the sole portion 2 is too hard, it is difficult to follow the bending of the upper 1 when kicking out during walking, so that it is easy to remove the foot. Therefore, the sole portion 2 is preferably made of a flexible material such as a sole of a running shoe.

When wearing the above-described footwear, the basic size of the mouth 3 is determined in advance by adjusting the opening degree of the adjustment opening 5 within a certain range. For this purpose, a foot is put into the footwear, and the upper belt 6 may be fixed at a position where the elastic member 7 appropriately presses the instep of the foot to obtain a pleasant tightening feeling. Once this adjustment has been made, it need not be changed unless the conditions change.

When putting on footwear, put your foot through the mouth 3 while standing. When the instep is pushed into the back side of the end of the instep cover 4 and the back surface of the heel 13a is moved along the upper surface of the heel guide portion 10, the instep 13b is protruded into the putting-in path. It hits the member 7 and this becomes an obstacle and it becomes difficult for the foot to enter. Therefore, when the foot 13 is further pushed in as shown in FIG. 5, the elastic member 7 is compressed in the thickness direction, and the foot can be put into the footwear as shown in FIG.

The instep 13b of the human foot and the back surface of the heel 13a are formed in a wedge shape when viewed from the side as shown by a one-dot chain line in FIG. 5, and even if the force for pushing the foot 13 is small, the wedge Due to the effect, the compressive force on the elastic member 7 is large. Therefore, even if the force for pushing the foot 13 into the footwear is not so great, the elastic member 7 is compressed in the thickness direction and the foot wearing space can be expanded, so that the foot can be put on smoothly.

Further, since the heel guide portion 10 is formed integrally with the reinforcing member 9 having sufficient strength, the heel guide portion 10 is not deformed even if the back surface of the heel 13a is rubbed when the foot is pushed in. .

Furthermore, when the foot is put in, the elastic member 7 presses the instep 13b. When the tip of the foot is bent during walking, the elastic member 7 is compressed by the instep 13b, but this is a surface compression and does not involve a wedge effect, so it is smaller than the compression force when the foot is put in. Thus, since the internal space of the footwear does not expand so much with a pressure applied at the time of walking, the foot 13 is stably held in the footwear and is not easily removed during walking.

Furthermore, the height of the heel guide portion 10 is set between a height H1 from the back surface of the heel 13a of the foot 13 to the rear upper end of the rib and a height h between 70% of the height H2. Therefore, it is easy to put on the foot and can hold the foot sufficiently, so it is easy to walk.
By covering 80% or more of the instep of the foot excluding the toes with the instep covering portion 4, the contact area between the instep covering portion 4 and the foot becomes large, so that the holding force of the foot is large.

Moreover, the unity of the upper 1 is ensured by fixing the size of the mouth 3. Since the upper cover 4 and the heel part 8 basically move together when the rear foot is swung forward during walking, as shown in FIG. 7, the foot heel and the foot heel part 8 are The relative relationship is difficult to change, and the flange 13a is difficult to separate from the bottom surface of the flange portion 8. If the wear mouth 3 is small, the integrity of the upper 1 is secured even better.

As described above, if the size of the mouth 3 is adjusted and fixed in advance with the instep belt 6, when you want to wear it, you can quickly put it in and put it in from the mouth 3 without bending. Since it is difficult to take off during walking, it is not suitable for mountain walking or speed running, but it is possible to provide footwear suitable for uses such as city walking.

When taking off the above footwear, it is only necessary to fix the heel of the footwear to be removed with the heel of the footwear on the opposite side and forcibly pull out the foot.

It should be noted that the opening width of the adjustment opening on the side of the mouth may be increased, and the upper exposed from the upper may be covered with an upper belt with an elastic member. In this case, the upper belt also serves as the upper covering portion.

(Embodiment 2)
8 and 9 show an embodiment of a sandal type footwear in which an elastic member is formed separately from the upper covering portion. In addition, the same code | symbol as the previous figure shall show the same member, and duplication of description of a function etc. is abbreviate | omitted.

The upper 1 is a portion that wraps the foot and is made of a material such as a chemical fiber or a natural fiber. The upper cover portion 4 is formed so as to cover almost the entire upper portion of the foot, but is divided into a front end portion 4a, a central portion 4b, and a rear portion 4c. The rear part 4c is divided into right and left, and an upper belt 6 is integrally provided on one side thereof, and can be attached to and detached from the other side of the rear part 4c by a surface fastener (not shown). The size of the mouth 3 can be adjusted by the fixing position of the upper belt 6.

On the back side of the upper cover 4, an elongated upper presser 15 that holds the upper of the foot is arranged. The upper presser 15 also constitutes a part of the upper cover portion, and the front end thereof is fixed to the front end portion 4 a of the upper cover portion 4.

As shown in FIG. 10, a slightly hard holding member 17 is integrally attached to the upper part of the upper presser 15 like a resin plate. The holding member 17 holds the entire shape of the upper presser 15. An elastic member 7 is provided on the back side of the upper presser 15. The elastic member 7 is formed of a member that can elastically expand and contract in the thickness direction. The elastic member 7 is disposed on the entire back surface of the upper presser 15, but may be disposed only on the rear rear surface of the upper cover portion 4.

The upper portion of the upper 3 including the upper portion 6, the upper portion 3, and the heel portion is fixed by the upper portion of the upper portion 6, and the size of the upper portion 3 is fixed. Is secured.

Similarly to FIG. 4, the height of the heel guide portion 10 is 70% of the height (H1) from the back surface of the heel 13a of the foot 13 that is worn to the upper end of the rib bulge at the rear of the rib 14 and 70% of this height. The height (h) is set between the heights (H2). Again, for the same reason as in the above embodiment, a few percent above or below the height (H1) or (H2) is within the error range.

As shown in FIG. 11, both sides of the rear part of the upper presser 15 are attached to both sides of the upper cover part 4 via elastic hanging members 16 such as rubber bands, and are always held upward.

When the foot is put into the footwear having the above-described configuration, the size of the mouth 3 is adjusted in advance with the upper belt 6 in the same manner as in the above-described embodiment 1, and the foot from the mouth 3 is put on while standing. Just push it in. FIG. 12 shows a state in which a foot is put on.
Even in this embodiment, although it is a footwear having a heel portion, the footwear can be worn without standing.

In addition, since the elastic member 7 is formed in the upper presser 15 provided on the back side of the upper cover portion 4, it is easy to hit the portion including the center line of the upper 13b of the foot. Therefore, the elastic member 7 can be effectively compressed when putting it on.

Further, since the elastic member 7 is provided on the entire back surface of the upper presser 15, the force in the direction of removing the foot is distributed over the entire back surface, and the force for compressing only the rear portion of the upper presser 15 is small. For this reason, it is difficult for the foot to slip out of the footwear during walking.

Furthermore, when the shoe is put on, the instep comes into contact with the back surface of the upper presser 15 including the elastic member 7 and is dragged toward the toe side. However, the upper presser 15 is held by the holding member 17 and the entire shape is held constant. No deformation due to pressure or friction. Therefore, the upper presser foot 15 is not deformed by being put in, and the foot can be always put in smoothly.

In addition, since the suspension member 16 that holds the upper presser 15 can be expanded and contracted, there is no obstacle to adjustment when the opening degree of the mouth 3 is adjusted. Further, since the upper presser 15 is held upward by the suspension member 16, the elastic member 7 does not sag inside the upper 1 even when not in use. Therefore, the front portion of the mouth 3 is not blocked, and the foot can always be put on smoothly.

Furthermore, as shown in FIG. 11, by suspending the upper presser 15 upward by the suspension member 16, both sides of the upper presser 15 push the wearer's mouth 3 left and right (the circumference of the wearer 3 is Therefore, the mouth 3 has a wide front part, and a wide foot can be smoothly put into the mouth 3.

The hanging member 16 need not be extendable. For example, as shown in FIG. 13, the upper belt 6 may be made of a hard material, and the upper presser 15 may be suspended from the center by the suspension member 16A. Further, the upper presser foot may be provided not on footwear but on footwear as shown in FIG. Further, when the upper presser itself is thick and has a shape retaining function as a whole, the holding member is not required.

In addition, the aspect which provides an elastic member in an upper foot is not limited to a sandal type footwear. For example, instead of providing the elastic member 7 directly on the upper cover portion 4 of the first embodiment, a structure may be provided in which the upper presser with the elastic member is provided on the back side of the upper cover portion. Further, an elastic member may be provided on the upper belt, and the upper covering portion may also be used.
