The present invention relates to a fastening device, and in particular to a fastening device used to be installed on an object.

Generally speaking, a wearable object can include a first side and a second side. The second side can be opposite to the first side. The first side and the second side are relatively close to fasten the wearable object. On the loading site. Taking a shoe as an example, it may further include a tongue, the tongue is located between the first side and the second side, and the shoe further includes a plurality of eyelets arranged on the first side and the second side, and the conventional shoe The strap can be tied through the eyelet of the shoe to tighten the object.

However, the shoelaces must be loosened before taking off the shoes, and the shoelaces need to be knotted again when putting on the shoes, which causes much inconvenience. In order to solve the above problems, some industry has developed a fastening device that can be arranged on the tongue and coupled to a tie line, which can pass through the eyelet of the shoe to replace the shoelace. By operating the fastening device, the tie line can be quickly retracted, and the shoes can be easily put on and taken off.

Unfortunately, this type of fastening device is fixed on the tongue during the post-production process of the shoe. In other words, if the shoe itself is not configured with a fastening device, it is extremely difficult for the user to couple the fastening device to the shoe.

After that, the reeling part R023 and the base R022 are combined to form a fastening system R0, and the tie line R01 is retracted through the reeling part R023 to tighten or loosen the object S1. In Figure 20, the object S1 is an example of a shoe, and although the tie line R01 in Figure 20 is coupled to the guide, in other embodiments, the guide can be replaced with a shoe eyelet. In addition, the object can be, for example, a protective gear, clothing, or other objects that need to be fastened when worn on the object to be worn, and the application of the present invention is not limited to this.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone who is familiar with this technique can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection of the present invention The scope shall be subject to the definition of the attached patent application scope.
