Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to sandals to be worn at the beach or by the pool, and one size can be adapted to fit various foot sizes, eliminating the need to prepare many sizes, and making it possible to walk while wearing the sandals. The shoes have been improved so that they can always be attached to the feet without easily falling off, even when swimming or swimming.

[Conventional technology]

Conventionally, as shown in Figure 4 of Utility Model Application Publication No. 57-74701 before amendment, a belt is provided at the front of a substantially foot-shaped bottom plate, and belts are provided at the middle and rear portions to connect both belts. There was one that had a belt attached to the top to wrap around the ankle.

[Problem that the idea aims to solve]

In the above conventional example, the belt that wraps around the ankle has a straight line when viewed from the side, so it will not fall off during use, but if the belt slips down, especially when swimming, the bottom part will wrap around the foot. There is a problem that it becomes difficult to swim because it separates from the back, and the belt also hurts when it hits the ankle.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides a substantially foot-shaped sole plate with a front instep band in the front part, a heel band in the middle part that goes backward, and a back instep band in the rear part that goes forward. The entire body is integrally molded with a stretchable material, and the front instep has a net-like part.
The heel band and the posterior instep band are crossed and connected to form a substantially V-shaped recess above the intersection, and an engagement band having a plurality of engagement parts is provided at the tip of one side of the posterior instep band. They are connected to each other, and the other end is provided with a locking body through which the engagement band is inserted and locked.

[Effect]

The present invention is constructed as described above, and includes the anterior instep bands 2, 2.
The ends of the heel bands 4 and 4 are placed together in advance and bonded using high frequency. To use this, insert your foot into the front instep band 2, place the heel band 4 against your heel, and then The engagement band 6 provided at one end of the instep band 3 may be inserted and locked into the other locking body 7. Since the front instep band 2 and the heel band 4 have elasticity, they deform according to the width, height, and length of the foot, and the engagement band 6 of the back instep band 3 is inserted through the locking body 7. Then, the engaging part 6
a...If you lock 6a in an appropriate position, it will fit snugly around your foot. Note that even if the foot is small and the heel cannot reach the heel band 4, if the engaging portions 6a...6a are locked at a position close to the base, the foot will fit snugly to the foot. In addition, the anterior instep bands 2, 2, the posterior instep bands 3, 3, and the heel bands 4, 4 are connected to the front, middle, and rear parts of the sole plate 1, respectively, so that the entire sole plate 1 covers the sole of the foot. It's hard to leave. Furthermore, the heel bands 4, 4 and the posterior instep bands 3, 3 are crossed and joined to form approximately V-shaped recesses 9, 9 that open above the intersection, so after wearing them on the foot, , the heel bands 4, 4 extend from their joints to the posterior instep bands 3, 3.
This causes the ankle to be pulled forward and diagonally upward, making it difficult to slip off the heel and positioning the ankle in the concave portions 9, 9.
The heel bands 4, 4 and the posterior instep bands 3, 3 do not touch the ankle. In addition, to take off the sandals of this invention, please press the back instep 3
What is necessary is to release the engagement between the engagement band 6 and the locking body 7 and remove the heel band 4 from the heel.

【Example】

Next, embodiments of the present invention will be described based on the drawings. The sandals of the present invention are entirely made of stretchable materials such as neoprene resin, urethane resin, EVA resin, and soft vinyl chloride resin. The approximately foot-shaped sole plate 1 has anterior instep bands 2, 2 on both sides of the front.
Heel straps 4, 4 are consecutively provided on both sides of the middle part, back instep belts 3, 3 are consecutively provided on both sides of the rear part, and fins 5 are consecutively provided on the front end. Sole plate 1 and anterior instep band 2, 2,
A groove 12 is provided at the continuous boundary between the heel bands 4, 4 and the back instep bands 3, 3 to facilitate bending. The fins 5 are used to obtain propulsive force during swimming, but are formed short so as not to provide support for walking. The anterior instep bands 2, 2 have net-like parts 2a, 2a except for the periphery.
On one side, a stretchable part 8 in which independent circular stretchable bodies 8a...8a are lined up is provided, and a stepped part is provided at the end edge of the stretchable part 8 and the tip edge of the other side. The stepped parts are high-frequency bonded together.
As shown in FIG. 7, the stretchable part 8 may have a coarse mesh shape, as long as it is more easily stretchable than other parts of the anterior instep band 2. It should be noted that, as long as the elastic part 8 has flexibility, such as the circular elastic body shown in FIG. Easy to expand and contract. The heel bands 4, 4 and the back instep bands 3, 3 intersect, and the intersecting parts are integrally connected, and substantially V-shaped recesses 9, 9 are provided above them. It has a net-like pattern from the base to the intersection, and beyond that, only the front side (the back side when manufactured) has a net-like pattern. Like the front instep bands 2, 2, the heel bands 4, 4 are each provided with a stepped portion at the distal end edge, and the stepped portions are bonded together using high frequency bonding. Incidentally, reference numeral 13 is a pinch piece, which is used by pinching when putting on or taking off the sandals of the present invention. Holes 10...10 are bored in the front instep bands 2, 2 in the parts that are connected to the bottom plate 1, and holes 10 are formed in the bottom plate between the heel bands 4, 4 and the back instep bands 3, 3. Holes 11, 11 are bored in the portions that are continuous with 1, respectively. These holes 10 and 11 are located in the anterior instep zone 2,
2. The heel bands 4, 4 and the back instep bands 3, 3 are used to adapt to the foot and easily deform, and to drain water, but this is not always necessary. An engagement band 6 is connected to the tip of one side of the rear instep bands 3, 3, and a locking body protruding in a gate shape on the front side (back side when manufacturing) is attached to the other end. 7 is provided. The engagement band 6 has an engagement portion 6a on the front side (on the back side when manufactured), one side of which is inclined like a ratchet tooth.
