Description

  The present invention relates to footwear.

  In general, as shown in FIG. 8, footwear such as sandals and slippers is composed of a bottom portion 102 on which a foot 50 is placed and is in direct contact with the sole 56 (in some cases, an insole member that is in contact with the sole 56, A simple structure comprising a bottom member in contact with the ground or floor surface and an upper covering portion 103 provided on the front side of the bottom portion 102 and formed so as to wrap around the upper portion 54 of the foot 50 and the tip of the foot. It has the advantage of being airy and easy to wear.

  However, on the other hand, such a simple footwear 100 composed of the bottom portion 102 and the upper covering portion 103 also has an aspect that it is easy to take off. That is, the upper covering portion 103 of this type of footwear 100 is generally formed larger than the average size of the upper foot of a person in order to make it easier to put on and off, so that the upper 54 and the upper covering portion of the foot 50 are formed. There is a gap 110 between the inner peripheral surface of 103. Therefore, when walking, due to the gap 110, the sole 56 is separated from the bottom 102 as shown in FIG. 8B, and a gap 115 is generated between the heel 52 of the foot 50 and the bottom 102, It may be difficult to walk or it may make a noise when walking. In particular, when a relatively intense movement such as a small run is performed, the footwear may come off due to the gap 115. Therefore, for example, the footwear disclosed in Patent Document 1 to Patent Document 3 is fixed to the foot heel by providing a stretchable band or the like that covers the heel of the foot or the heel of the foot from behind, The sole 56 is prevented from separating from the bottom 102.

  However, even if the heel is fixed with a string, a band, or the like, it is difficult to say that the sole 56 can be completely prevented from separating from the bottom 102. This is because the gap 110 still exists between the upper 54 of the foot 50 and the inner peripheral surface of the upper covering portion 103, and as long as there is a degree of play up and down along with this gap, It is inevitable that the legs flutter. However, on the other hand, the gap 110 also has a side surface that keeps the opening of the upper covering portion 103 large and makes it easy to insert the foot into the upper covering portion 103 (easy to wear). That is, in the type of footwear shown in FIG. 8, it is better that the gap 110 exists when putting on and off, and conversely, it is better that the gap 110 does not exist when walking.

  The present invention has been made paying attention to the above-described problems, and an object of the present invention is to provide footwear that is easy to put on and take off, and that increases the sense of unity with the foot during walking and is difficult to take off.

  In order to achieve the above-described object, the footwear of the present invention includes a bottom portion on which a foot is placed, a deformable instep covering portion that covers the instep of the foot, and pulling the instep covering portion to hang it on the foot heel. A tow that is turned, and the tow is connected to the instep covering so that it pulls the instep covering against the instep when it is hung around the toe It is characterized by.

  According to the above configuration, when the traction body is not pulled, a gap can be left inside the upper covering portion (between the instep and the inner peripheral surface of the upper covering portion). It can be easily put on and off. In addition, if you insert your foot into the instep cover and hang the towing body around the toe of the foot, the instep cover will be pulled by the towing body and applied to the instep of the foot. The sole is pressed against the bottom of the footwear by the pressing force of the part. At the same time, the traction body hung around the heel prevents the foot from slipping rearward of the footwear and fixes the heel to the bottom of the footwear. In other words, because the downward pressing force by the instep cover and the downward reaction force that the heel receives from the towing body, the front and back of the ankle are attracted to the bottom of the footwear, and the sole firmly adheres to the bottom of the footwear. A sense of unity with the feet increases, making it difficult for the soles to separate from the bottom (the footwear is difficult to remove).

  In the above configuration, it is preferable that the upper covering portion is provided with a notch that allows a change in the circumference thereof. As a result, the upper covering portion is easily deformed, and the adhesion between the upper covering portion and the instep is enhanced. Moreover, in the said structure, an instep coating | cover part may have two coating bodies which can deform | transform individually, and the both ends of a traction body may be connected to the respectively separate coating body. In this case, if the two coverings are separated from each other on both sides of the upper covering part and are positioned at the front and rear, it is possible to tighten the upper part of the foot from both sides by the upper covering part. ) Can be further increased. Further, in the above configuration, the upper covering portion includes a covering main body and a pressing body that is connected to the inner peripheral surface of the covering main body and presses the instep of the foot, and both ends of the traction body are connected to the pressing body. May be. As a result, the instep can be pressed locally and efficiently, and the traction force to be applied to the traction body can be reduced. In the above configuration, as described above, a gap may be left inside the upper covering portion (between the instep and the inner peripheral surface of the upper covering portion) without pulling the towing body. In that case, it is preferable to form a self-supporting structure so that the mouth is not crushed. By doing so, it is easy to put on and wear it.

  ADVANTAGE OF THE INVENTION According to this invention, the footwear which it is easy to take off and can wear and becomes difficult to take off because a sense of unity with a foot increases at the time of walking.

Embodiments of the present invention will be specifically described below with reference to the drawings.
1 to 3 show a first embodiment of the present invention. As shown in the figure, the footwear 1 of the present embodiment wraps around the instep 54 and the toes of the foot 50 provided on the front side of the bottom 2 where the foot 50 is placed and in direct contact with the sole 56. The upper covering portion 3 is formed as described above. The bottom 2 is formed of a synthetic resin such as polyurethane or polyethylene, or synthetic rubber, and may be formed of, for example, an insole member that contacts the sole 56 and a bottom member that contacts the ground or the floor surface. . Further, the upper covering portion 3 is formed so as to cover the upper 54 and the tip of the foot by forming a substantially dome-shaped space S into which the tip side of the foot can be inserted, and is integrally connected to the bottom portion 2. It is formed of a deformable material, for example, a synthetic resin such as polyurethane or polyethylene, a foaming synthetic resin such as polyurethane, polyethylene, or EVA, or a synthetic rubber or synthetic leather.

  In addition, in this embodiment, the upper covering part 3 has the notch 5 extended in the front from the opening edge part, and these notches 5 are the circumference changes (deformation) of the upper covering part 3. Is to be tolerated. In order to prevent foreign matter from entering the upper covering portion 3 through the notch 5, an elastic cover (not shown) may be attached to the notch 5 so as to close the notch 5. In the present embodiment, the upper covering portion 3 covers the entire front side of the foot including the upper 54 and the toes of the foot 50, but may cover only the upper 54 so as to expose the toes. .

  In addition, the footwear 1 of the present embodiment includes a tow body 4 that pulls the upper covering portion 3 and hangs around the toe 52 of the foot. The tow body 4 is formed as a string-like member, and when it is hung around the heel 52 of the foot 50, both ends of the tow body 4 are pulled so that the upper covering portion 3 is pulled and applied to the upper 54 of the foot 50. It is connected to both sides of the covering 3. Specifically, on the one hand, the both ends of the tow body 4 are inserted through cylindrical portions (formed by cloth material or the like) 6 provided at both lower end edges in the vicinity of the opening edge of the upper covering portion 3. It extends upward across the notch 5 and is connected to both sides of the tongue piece 3a of the upper covering portion 3 extending in a cantilevered manner by the notch portions 5 on both sides. On the other hand, the traction body 4 extends downward in a loop from the both tube portions 6 to the rear side of the footwear 1. In addition, as long as the traction body 4 can produce the traction force which can apply the instep coating | cover part 3 to the instep 54 of the leg | foot 50, the whole or one part may have a stretching property. For example, the traction body 4 can be formed from one woven with synthetic fibers, synthetic resin such as polyurethane, synthetic rubber, or any combination thereof.

  FIG. 1A shows a state in which the traction body 4 is not pulled, and FIG. 1B shows a state in which the traction body 4 is pulled and the upper covering portion 3 is pulled toward the bottom 2 side. In a state where the towing body 4 is not pulled (the state shown in FIG. 1A), a gap is left inside the upper covering portion 3 (between the inner peripheral surface of the upper covering portion 3 and the upper 54 of the foot 50). Therefore, it is possible to easily put off the footwear 1. Further, as shown in FIG. 2, when the foot 50 is inserted into the upper covering portion 3 and the towing body 4 is hung around the heel 52 of the foot 50, the upper covering portion 3 is pulled by the pulling body 4 (the arrow in the figure). a) and b)) Since the contact with the upper 54 of the foot 50 is eliminated, the gap between the upper covering 3 is eliminated, and the sole 56 is pressed against the bottom 2 of the footwear 1 by the pressing force F <b> 1 by the upper covering 3. At the same time, the traction body 4 hung around the heel 52 prevents the foot 50 from shifting to the rear of the footwear 1 and fixes the heel 52 to the bottom 2 of the footwear 1. That is, the front and back of the ankle 58 are attracted in a V shape to the bottom 2 of the footwear 1 by the downward pressing force F1 by the upper covering portion 3 and the downward reaction force F2 received by the heel 52 from the towing body 4, and the sole 56 is Since the foot 1 is firmly adhered to the bottom 2 of the footwear 1, the sense of unity between the footwear 1 and the foot 50 is increased during walking, and the sole 56 is difficult to separate from the bottom 2 (the footwear 1 is difficult to remove). Further, in this case, since the upper covering portion 3 is provided with the notch 5 that allows the circumference change thereof, the upper covering portion 3 is easily deformed, and the upper covering portion 3 and the upper 54 of the foot 50 are in close contact with each other. Increases nature.

  Thus, according to the present embodiment, it is possible to provide the footwear 1 that is easy to put off and put on, and that increases the sense of unity with the foot during walking and is difficult to take off.
