Description

TECHNICAL FIELD

The present application relates to the technical field of shoelaces, and in particular to a tightening buckle for stabilizing shoelaces.

BACKGROUND

Shoelaces are rope tools that used to adjust tightness of shoes and ensure comfort of feet. The shoelaces have always been tightened by a way of shoelaces cross knotting, while the way of shoelaces cross knotting is very cumbersome. In addition, the shoelaces are often too tight, too loose and loosened when walking and exercising, resulting in a lot of inconvenience.
Currently, it is known that footwear products control tightening and loosening of the shoelaces by designing a rotary buckle for the shoelaces. However, existing rotary buckles do not have a close enough fit structure among them, so that during use or after a period of application, components of the rotary buckles are prone to disengage from each other, and entire rotary buckle fall apart, thereby service life of the rotary buckles is limited.

In some embodiments of the present disclosure, the shoelace winding member is configured to be provided inside of the upper connector and the lower connector, and the base is configured to be mounted on outside of the lower connector.
In some embodiments of the present disclosure, a shoelace is connected between the lower connector and the shoelace winding member, the clamping piece is rotated to drive rotations of the upper connector and the shoelace winding member and also control the shoelace winding member to be coiled around the shoelace winding member or be loosened from the shoelace winding member.
In some preferred embodiments of the present disclosure, the upper connector includes an outer housing and an inner housing, the outer housing is configured to be mounted on outside of the inner housing, and the inner housing includes a mounting part disposed around a central axis of the inner housing and a mounting hole formed by the mounting part. And bottom of the mounting part is configured with a snap-fit part projecting inwardly, the shoelace winding member is configured with a mounting block corresponding to the mounting hole and the snap-fit part, and the mounting block is configured to be snapped into the mounting hole.
In some preferred embodiments of the present disclosure, the bottom of the mounting part is further configured with a plurality of slots, and the shoelace winding member is configured with convex grooves corresponding in shape and size to the slots. By mating connection of the slots and the convex grooves, an overall structure stability of the tightening buckle for stabilizing shoelaces of the present disclosure can be further increased.
In some preferred embodiments of the present disclosure, the lower connector includes a hollow portion for providing space to mount the shoelace winding member, the hollow portion is configured with serrations equally spaced around periphery thereof, and the serrations is configured to be aligned with an end face of the shoelace winding member. Herein the serrations can act as blocking limits to prevent the shoelace winding member from rotating itself without manual control.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Preferred embodiments of the present disclosure will be described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are intended only to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
As shown in FIG. 1 to FIG. 3 , in some embodiments of the present disclosure, a tightening buckle for stabilizing shoelaces is provided, including a clamping piece 1, a base 2, a shoelace winding member 3, an upper connector 4 and a lower connector 5, and all of them have a cylindrical geometry. Herein the upper connector 4 includes two parts of an outer housing 41 and an inner housing 42.
Starting from top to bottom, the clamping piece 1 is mounted on the outside of the upper connector 4, that is, on the outside of the outer housing 41. A top periphery of the outer housing 41 is provided with a number of mounting grooves 411 arranged in a circular pattern, and the clamping piece 1 is snapped into the mounting grooves 411.
Similarly, the outer housing 41 is fixedly connected to the inner housing 42 by means of snap-fit. The inner housing 42 includes a mounting part 421 disposed around a central axis of the inner housing 42 and a mounting hole 422 formed by the mounting part 421. And bottom of the mounting part 421 is configured with a snap-fit part 423 projecting inwardly, i.e., in a direction of the center axis. Correspondingly, the shoelace winding member 3 is configured with a mounting block 31 corresponding to the mounting hole 422 and the snap-fit part 423, and the mounting block 31 is snapped into the mounting hole 422, thereby realizing a fixed connection between the inner housing 42, i.e. the upper connector 4, and the shoelace winding member 3.
The bottom of the mounting part 421 is further configured with a plurality of slots 424, and correspondingly, the shoelace winding member 3 is configured with convex grooves 32 corresponding in shape and size to the slots 424. When installation, the convex grooves 32 are snapped into the slots 424 to increase firmness of the installation and the stability of gearing.
Then down to the lower connector 5, there are two winding places on the outside of the lower connector 5, and four holes are opened on the shoelace winding member 3. A shoelace 6 passes through the two winding places on the lower connector 5 and the four holes, so that the shoelace winding member 3 can rotate relative to the lower connector 5 when a user rotates the clamping piece 1, which in turn coils the shoelace 6 around the shoelace winding member 3, or loosens it from the shoelace winding member 3.
The lower connector 5 includes a hollow portion 51 for providing space to mount the shoelace winding member 3, the hollow portion 51 is configured with serrations 52 equally spaced around periphery thereof, and the serrations 52 is configured to be aligned with an end face of the shoelace winding member 3, thereby preventing the shoelace winding member 3 from rotating easily.
The lower connector 5 is further configured with a limiting portion 53 disposed around an inner wall thereon, and a bottom of the shoelace winding member 3 is located below the limiting portion 53. In this way, it creates a limiting effect on the shoelace winding member 3. Further, the lower connector 5 is also configured with a lug boss 54 disposed around bottom thereon and the base 2 is configured to be snapped onto the lug boss 54.
Finally, it should be noted that the above is only some preferred embodiments of the present disclosure, and is not intended to limit the present disclosure. Although the present disclosure has been described in detail with reference to the foregoing embodiments, for an ordinary person skill in the art, it is still possible to make modifications to the technical solutions described in the preceding embodiments, or to make equivalent substitutions for some of technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the scope of the protection of the present invention.
