Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a shoe having a tightening device, and more particularly, a tightening device that can tighten a shoe instep with a simple operation and does not loosen is integrally connected to a tongue of the shoe. It's about shoes.

[0002]

[Prior Art]

 Conventionally, as a means for tightening and fixing a shoe upper, there is a shoelace locking device of Japanese Utility Model Publication No. 60-41125 shown in FIGS. 7 and 8. Such a sock-lace locking device has cylindrical stoppers loosely fitted to both ends of a hollow cylindrical body so that the stoppers can be moved forward and backward, and springs are used to extend outwards. The structure was such that the position of the through hole of the lace was shifted and the restoring force of the spring could fix the lace through the through hole. However, in the above-mentioned conventional product, the shoelace locking device is separated from the main body of the shoe, so that the shoelace floats on the instep cover during walking and lacks stability, especially when performing a violent action such as running. The locking device made of a hard material such as plastics violently shakes on the instep cover, hits the instep of the foot strongly, and causes discomfort to the wearer of the shoe. There is a loosening defect in the laces. Further, in the conventional product, since the main body of the device is formed of a cylindrical body, it is not possible to attach it to the main body of the shoe as it is, and it is necessary to form the main body separately from the main body of the shoe. Further, there is a so-called string holder as shown in FIG. The basic structure of such a string holder is composed of an inner and outer cylindrical body formed in a cylindrical shape, a spring is provided at the bottom of the inner cylindrical body, and the string is locked by using the pushing force of the spring. Since the string hole is provided on the extension of the moving direction of the spring, there is a limit to the downsizing of the string holder itself, and it is not suitable to be attached to shoes. Therefore, the above-mentioned conventional products were still unsatisfactory in terms of function and design.

Therefore, an object of the present invention is a shoe in which a shoelace tightening device is integrally attached to a tongue of a shoe so that the shoelace can be tightened and fixed by a simple operation.

[0004]

[Means for Solving the Invention]

 In order to achieve the above-mentioned object, the present inventor has conducted earnest research and has provided a shoe having the following configuration. That is, the shoe of the present invention comprises a shoe body and a shoelace tightening device attached to the tongue of the shoe body, the shoelace tightening device comprising a hollow chamber body and a frame body surrounding the sides of the chamber body. And a spring that is mounted in the center of the chamber body and pushes up the ceiling of the chamber from the inside, and the hollow chamber body and the frame body separate the spring mounting position on each side wall portion. Shoelace insertion holes for inserting shoelaces are formed at symmetrical positions, and the shoelace insertion holes are provided so as to be vertically aligned so as to align when the chamber body is forcibly pushed against the spring. A new technical means was adopted in which the shoelace was connected to the tongue piece through a pedestal provided on the base side of the frame of the lace tightening device and the shoelace was movably inserted into the shoelace insertion hole.

[0005]

[Action]

 According to the present invention, since the shoelace tightening device formed in a thin layer is integrally connected to the tongue of the shoe, the operation of the shoelace is very natural and is easy for a weak person to operate. It is possible to provide a tightening operation.

[0006]

【Example】

 The shoe of the present invention will be described based on the embodiment shown in the drawings. First, FIG. 1 is a perspective view of a shoelace tightening device 3 attached to the shoe of the present invention as seen from above, and FIG. 2 is a side view thereof. FIG. 3 is a sectional view of the shoelace tightening device 3, and FIGS. 4 and 5 are perspective views showing a state in which the shoelace tightening device 3 is attached to the tongue piece 2 of the shoe. As shown in FIGS. 1 to 3, the shoelace tightening device 3 is formed of a frame body 5 surrounding the outer side of the hollow chamber body 4, and the chamber body 4 is provided with a spring 6 provided in the chamber body 4. The shoelaces 7, 7 pushed up and passed through the shoelace insertion holes 8, 8 are sandwiched and locked between the shoelace insertion holes 8, 8. That is, the shoelace insertion holes 8 and 8 are provided so as to be slightly shifted vertically so that the shoelace insertion holes 8 and 8 are aligned with each other when the chamber body 4 is forcibly pushed against the spring 6. It is formed so that the shoelaces are locked by the restoring force of 6. At this time, the spring 6 is arranged in the center of the chamber so that the pushing force or the restoring force of the spring 6 acts on the chamber 4 in a well-balanced manner. Further, as shown in FIGS. 2 and 3, the shoelace insertion holes 8 and 8 are provided at symmetrical positions with the spring 6 being attached, and the two shoelace insertion holes 8 and 8 are inserted. It is installed at a position where tensile forces of 5 and 5 work equally. At this time, in order to make the shoelace tightening device 3 itself as compact as possible, the pitch width of the springs 6 is made small, or the absolute width of the spring 6 itself is made small by making the number of pitches as small as possible. It is possible to form the tightening device 3 in a thin layer.

Next, as shown in FIGS. 3 and 4, the shoelace tightening device 3 is provided with a pedestal 10 at the base side of the frame body 5 and is connected to the tongue piece 2 via the pedestal 10. At this time, the pedestal 10 is made thin so that it can be joined to the tongue 2 and can be sewn to the tongue 2. If sewing is taken into consideration, the fine groove 11 may be engraved along the seam allowance as shown in FIG.

FIG. 6 shows another embodiment of the mounting method, in which a pedestal 10 is provided with a through hole 13 through which the mounting belt 12 is passed, and the tongue 2 is mounted through the belt 12 through which the through hole 13 is passed. You can also At the time of attaching the shoelace tightening device 3 to the tongue piece 2, it can be properly attached using not only a sewing method but also an adhesive. Further, the shape and size of the pedestal 10 can be freely selected in consideration of the connecting force to the tongue piece 2.

When operating the present invention, as shown in FIG. 5, the tongue piece 2 of the shoe is grasped like a grab and is attached to the tongue piece 2 on the chamber body 4 of the shoelace tightening device 3. The shoelace can be tightened with a simple operation such that the thumb of the hand is touched with, the chamber body 4 is pushed in with the thumb, and the shoelace is pulled with the other hand. Therefore, in terms of operation, the tightening operation can be easily and simply performed by simply grasping the tongue piece 2 and pushing the chamber body 4 in, which is an extremely natural operation.

[0010]

[Effect of the device]

 Therefore, according to the present invention, it is possible to make the shoelace tightening device 3 thin and compact by reducing the number of pitches of the spring 6 that moves up and down and pushes up the chamber body 4 as much as possible, and is formed in a thin layer. Since the shoelace tightening device is integrally connected to the tongue of the shoe, there is a sense of unity with the main body of the shoe, and it is a natural operation to grasp the tongue in operation and the pressing force of the thumb is applied. It is a device of extremely high practical value that can be used in all types of shoes, including running shoes, so that even a weak person can easily perform shoelace tightening operation by making it work well.
