Description

[Detailed Description of the Invention] The present invention relates to athletic shoes, especially assembled athletic shoes suitable for running long distances such as marathons.

Conventionally, this type of athletic shoe for competitions was simply made by inserting the shoelace through a plurality of eyelets provided at opposing positions in the front part of the front part and tightening the shoelace at the part of the part. Since the foot and ankle are not held tightly, when going around the curve, centrifugal force acts and the foot naturally slides inside the shoe, and this sliding constantly shifts the position of the sole of the foot. The bones, metatarsals, and their bending and stretching forces cannot be fully exerted, and the kicking force is greatly reduced, and even when sprinting, the foot instantly moves forward or backward due to inertia and rebound impact from the road surface. There were defects such as slipping and hindering kicking force.

In the past, the size and height of each person's feet varied greatly, so conventional athletic shoes made by simply tightening the front part of the shoe with a single shoelace did not allow for the three-dimensional curved shape of the foot. Shoelaces often come loose during sprinting because they do not fit perfectly, and it is easy to have to retie the shoelaces during a competition, which can cause defects such as causing fatal blows to runners in competitive races. there were.

The present invention is an attempt to eliminate the above-mentioned conventional defects, and its purpose is to securely tighten the front part of the shoe with the first shoelace 2, and to tighten the heel and ankle parts of the foot that require the most tightening. By lifting the shoes above the heel with another second shoelace 3 and tying them firmly at the ankle, it is possible to reliably suppress the slippage of the foot inside the shoe and perform a suitable competition. Especially the second shoelace 3
By inserting the second shoelace 3 into the connecting band 4, the second shoelace 3 can be reliably held in a predetermined position without being disturbed or coming off. Even if one shoelace 2 becomes loose, the heel and ankle are tightened to prevent the shoe from being accidentally removed from the foot.

Still another object of the present invention is to provide appropriate elasticity through the shoelace by forming an elastic body such as a rubber band on a part of the second shoelace 3 that surrounds the lower heel periphery. It is intended to act on the heel surface to better adapt to the size of the foot and provide a light and comfortable feeling when worn.

Embodiments of the present invention will be described below with reference to the drawings.

Example 1 As shown in Fig. 1, the front part of the shoelace is split open to the left and right, a plurality of through holes 1 are provided on both sides, and the first shoelace 2 is inserted into the through holes 1. Then, the passage band 4 through which the second shoelace 3, which is separate from the first shoelace 2, is inserted is passed from the lower part of the heel on the outer surface of the shoelace to the upper part C of the front press-through hole and sewn 5. , 5, and insert and pull out the second shoelace 3 from the insertion lower part 7 with both ends of the second shoelace 3 on the front part, the front part is tightened with the first shoelace 2, and the heel and ankle parts are tightened with the second shoelace. It is tightened with shoelaces 3.

In the figure, 8 is an outer collar, 9 is an inner collar, 10 is a heel reinforcement piece, 11 is a tongue piece, and 12 is an outsole.

Embodiment 2 What is shown in FIG. 2 shows another embodiment of the present invention.
At least a portion of the shoelace 3 that can be inserted into the full band 4,
The other parts are the same as those shown in FIG. 1 except that it is formed by an elastic body 6 such as a rubber band.

! In either of the above embodiments, after tightening the front part of the shoelace with the first shoelace 2, the tongue piece 11 is bent if necessary, and a casing is attached to the back side of the tongue piece 11, or a second shoe is attached to the upper surface of the tongue piece 11. A connecting band (not shown) for the laces 3 may be provided and a means for inserting and locking the second shoelace 3 may be provided.

This design uses two shoelaces of completely different systems, like the Imperial Prince, and the front part is the well-known first shoelace 2, and the heel part and foot a.
Since the outer side of the heel part is surrounded and tightened by the second shoelace 3 around the heel part through the continuous band 4, the front part of the shoe is simply opened and opened like in the conventional assembly movement. This is completely different from the case where only the first shoelace 2 is used to tighten the shoelaces 2, and the second shoelace 3 is inserted into the heel and ankle areas, which require the most tightening during competition, through the band 4. This allows the shoe to be held evenly around all four circumferences through the shoe cover, which not only allows the foot to fit well inside the shoe and completely prevent the foot from sliding inside the shoe, but also allows the foot to exert sufficient kicking force while running. Not only can this further improve functionality, but it can also prevent Achilles' injuries, reduce foot fatigue, and allow the required motor functions to be performed smoothly and fully.

Furthermore, by tightening the second shoelace 3, the foot is raised above the heel, and by tightening the second shoelace 3 firmly at the ankle, slipping of the foot inside the shoe is reliably suppressed, making it suitable for competitions. In particular, since the shoelace 3 is inserted into the continuous band 4, there is no risk that the second shoelace 3 will be disturbed or come off, and it can be held in a predetermined position reliably. .

In a second embodiment in which a part of the second shoelace 3 is made of an elastic body 6 such as a rubber band shown in FIG. 2, the elastic body absorbs and cushions the bending and stretching of the ankle during running. In addition to being able to become familiar with the bending and stretching movements of the ankle,
Even when the second shoelace 3 of the temporary base is tightened strongly, it does not bite directly into the foot or press it partially, but uses appropriate elasticity to bring the shoelace close to the foot, giving a very light feeling of wear. .

In addition, even if your feet have grown since you bought the shoes, such as when you were a teenager, you can still use the original shoes because the rubber band of the shoelaces will stretch to a certain extent. 2 and 3 have a double tightening effect, so even if one shoelace becomes untied, the other shoelace will tighten and have the same effect as a double safety device. be.
