When use, a fabric shoelace or a serrated plastic groove is passed into the retaining base, and ends of the ratchets are provided for clamping a surface of the fabric shoelace or plastic shoelace to facilitate adjusting the tightness of the shoelace.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a shoelace fixing technique for tying a shoelace and preventing the shoelace from being separated, and more particularly to a shoelace fastener and a shoelace structure that facilitate tying a shoelace and adjusting the tightness of the shoelace.
2. Description of the Related Art
In general, a shoe with a tying function usually includes a shoe surface disposed at the top surface of the shoe, and the surface has pairs of left and right symmetrical shoelace eyelets provided for passing through the shoelace eyelets alternately and adjusting the length of the shoelace that passes through the shoelace eyelets in order to adjust the tightness of the shoelace and achieve the effects of tying and fixing the shoe. Because the length of the upper shoe surface or the number of shoelace eyelets varies with different types of shoes, it is necessary to provide shoelaces with different lengths for different types of shoes, or else the shoes cannot be tied securely and may fall off easily.
However, a conventional shoelace still has the following drawbacks that require further improvements:
1. Most shoelaces are designed with one length, and both ends of a shoelace have a shoelace head individually provided for passing through the shoelaces eyelets alternately, such that if the shoelace is too long or too short, then another shoelace of an appropriate length must be used. If the shoelace head is cut to fit the length, then the shoelace may lose structure integrally or may easily splits from end.
2. When a conventional shoelace is used for tying, repeatedly adjusting the length of the shoelace between the shoelace eyelets is necessary, and then tie a bow-tie or any other types of knot to fix both ends of the shoelace. Obviously, the conventional way of tying the shoelaces takes time and effort. Furthermore, the shoelaces may be loosened easily.
3. The remaining section of a tied shoelace may be hooked by an object and cause the tied shoelace to loose easily, so shoe wearers may trip over the loosened shoelace and get hurt.
4. The knot of a tied shoelace is protruded and dropped at the shoe surface with lace holes. For exercises or ball games, the knot may touch the ball surface to produce irregular bouncing movements, and all these drawbacks are annoying to shoe wearers. Furthermore, a conventional fabric shoelace may get dirty easily and generally comes with no waterproof effect.
In view of the aforementioned shortcomings of the conventional shoelaces, the inventor of the present invention designed a novel shoelace with a shoelace fastener, wherein the shoelace fastener is provided for fastening a fabric shoelace or a plastic shoelace to overcome the conventional way of adjusting the length of the shoelaces and the drawbacks of a conventional shoelace knot. The design of a ratchet in accordance with the invention provides a convenient way of adjusting the length of the shoelace easily to achieve the effects of adjusting the tightness of the shoelace effectively and significantly enhancing the convenience for using.

In addition, a serrated structure 112 is disposed on an internal surface of the first retaining base 12, which the internal surface opposites to a surface of the first lace 11 of the ratchet 13.
With reference to FIGS. 3 and 4 for a shoelace fastener installed onto a surface with lace holes in accordance with a first preferred embodiment of the present invention, the shoelace 20 is passed through each shoelace eyelet 31 of the shoe surface 30 with lace holes, and both ends of the shoelace 20 are passed out from the shoe surface 30 with lace holes, and passed into the first retaining base 12 (either in the same or opposite direction) to press the ratchet 13 down, such that both ends of the shoelace 20 can be passed into the first retaining base 12. After the ratchet 13 is released, the ratchet 13 is pressed downwardly by the resilience of the elastic clipping element 14, and the shoelace 20 is clamped and fixed by the catch portion 133 and the serrated structure 112 on the surface of the first lace 11, and thus it is not necessary to tie the shoelace 20 anymore so as to provide a convenient application, and the present invention also makes use of pressing the ratchet 13 downwardly to produce a release effect and provide a quick and convenient way of adjusting the tightness of the shoelace 20. In addition, the collar 111 of the first lace 11 is provided for passing the remaining portion of the shoelace 20 and preventing such portion from being warped.
With reference to FIGS. 5 to 8 for a three-dimensional view and a schematic view of a shoelace fastener structure, a schematic view of installing a shoelace fastener onto the shoe surface with lace holes, and a schematic view of adjusting a shoelace in accordance with a first preferred embodiment of the present invention respectively, a second retaining base 15 is disposed at another end (which is also the original position of installing the collar 111) of the first lace 11, and the second retaining base 15 also includes a ratchet 151 and an elastic clipping element 152 therein, and an internal surface of the second retaining base 15 is also a serrated structure 153 opposite to the surface of the first lace 11 of the ratchet 151, such that both ends of the shoelace fastener can be used for fixing the shoelace 20 (particularly for a fabric shoelace).
