Description

Lace structure with integrated fused shoelace head

The present invention relates to a shoelace structure, and more particularly to a shoelace structure having a lace head that is integrally fused.

According to the conventional shoelace 100, it is used for attaching to a casual shoe or a sports shoe, and the shoelace 100 is tightened through the shoelace hole to achieve the effect of fixing the shoe body. As shown in FIG. 1 , a three-dimensional structure diagram of a shoelace head sleeve 10 and a belt body 11 is known, wherein the shoelace head sleeve 1 is a hollow pipe body for being sleeved on the joint portion of the belt body 11 . 111. By using the tightening action of the shoelace head sleeve 10, the joint portion 111 can be prevented from blooming, but the shoelace 100 has the following disadvantages in use:

First, the strength of the shoelace head sleeve 10 for clamping the joint portion 111 is not sufficient. The shoelace 100 often causes the joint portion 111 to fall off from the shoelace head sleeve 10 after being used for a period of time, thereby causing the The phenomenon in which the joint portion 111 blooms occurs.

Secondly, when the joint portion 111 and the shoelace head sleeve 10 are detached, the user usually replaces the new shoelace, which is not durable, and causes considerable trouble to the user in use.

Thirdly, the shoelace 100 is mostly woven by a plurality of strands 12 like braided hair. Since the gap between the plurality of strands 12 is too large, it is necessary to pressurize the sleeves 10 again. The tight-fitting effect prevents the occurrence of flowering, but this design not only complicates the processing, but also increases the manufacturing cost of the operator.

Therefore, how to develop a shoelace structure with a fused lace head, which can solve the above defects is the motive for the new research and development.

In view of the above-mentioned shortcomings of the prior art, the present invention provides a shoelace structure having a one-piece fused shoelace head, which is mainly for improving the durability and saving the processing cost of the operator.

Therefore, the present invention relates to a shoelace structure having an integrated fused shoelace head, comprising: a plurality of braided wires, each of the wires having a fused end portion on the same side, and each of the fused ends is disposed at an outer periphery thereof. There is a fusion zone, and the fusion zone of each of the wires is welded integrally with the fusion zone of each adjacent wire to form an integrally fused shoelace head.

The shoelace structure having the integrally fused shoelace head according to the above, wherein the wire material is thermoplastic polyurethane (TPU) or thermosetting polyurethane (PU).

Compared with the efficacy of the prior art: the present invention provides a lace structure having a integrally fused lace head, wherein the fusion ends of the plurality of wires are welded and heated, and the plurality of wires are welded and integrated by heat. The fusion temperature rises to the melting point range of the fusion zone, so that the fiber surface of the fusion zone of the plurality of wires is softened and partially fused to each other, thereby improving the durability and the occurrence of flowering, and does not need to pass through the conventional shoes. The lead bushing is tightly bundled, thereby saving the processing cost of the operator.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

As shown in FIG. 2 and FIG. 3, the structural diagram of the present invention and its perspective view are respectively displayed. The present invention provides a shoelace structure 200 having a laced head integrally fused, which mainly comprises:

The plurality of braided wires 20 each having a fused end portion 21 on the same side, each of the fused ends 21 being pressurized and heated to cause the fused ends 21 of the plurality of wires 20 to be mutually The weld is integrated to form a one-piece fused shoelace head 22.

The wire 20 is a thermoplastic polyurethane (TPU) or a thermosetting polyurethane (PU). During the production, the fusion end portion 21 is heated and pressurized, and the fusion end portion 21 of the plurality of wires 20 is melted into one body, as shown in FIG. The processing steps of the lace structure 200 are completed by forming a tight fastening structure for each of the wires 20.

As shown in FIG. 5, in the present embodiment, four wires 20 are taken as an example, but are not limited thereto. A fused region 211 is disposed at an outer periphery of the fused end portion 21 of each of the wires 20, and the fused region 211 of each of the wires 20 is fused to the fused region 211 of each adjacent wire 20 to form a body to form a body. The shoelace head 22 is integrally fused.

As shown in FIG. 6 , in the embodiment, a plurality of the wires 20 are taken as an example. When the wires 20 are heated, the wires 20 are different in heat, wherein the wires 20 are not welded and are still integrated into a body to form. The shoelace head 22, which is integrally fused, has an overall structure as described above, and the wires 20 are tightly coupled to each other, thereby increasing the overall utility.

In the present invention, the wire 20 of the TPU material or the PU material generates liquid viscosity when heated, and is bonded to the adjacent fusion zone 211 to be cooled and hardened, thereby generating strong adhesion and firmness, without using shoes such as shoes. The belt requires a complicated step of being compressed and tightened by the shoelace head sleeve, and also saves the manufacturer's processing materials, further reducing the cost and manufacturing time, and improving the service life of the shoelace structure 200.

The structure and the configuration description of each component of the shoelace structure having the integrally fused shoelace head according to the above-mentioned novelty are provided.

The novel has the following effects:

First, the creation is a complicated processing step, which is only directly heated and pressurized. This method can form a tight shoelace head structure without the phenomenon of conventional flowering. The finished product is applied to various footwear, this The new approach improves the technology that is not possible with traditional practices, and reduces consumables and saves the processing costs of the operators.

Secondly, due to the above-mentioned method, the shoelace structure 200 can not only reduce the damage rate during use, but also provide excellent usability and stability of the consumer.

In summary, the above embodiments and drawings are only the preferred embodiments of the present invention, and the scope of the novel implementation cannot be limited thereto, that is, the equal changes and modifications made by the scope of the novel application are all This new patent covers the scope.
