Description

LACE PART CAPABLE OF QUICK SHOELACE OPERATION AND FOOTWEAR HAVING THE SAME}

The present invention relates to a shoelace, and more particularly, to a shoe article in which the shoelace can be easily tightened and unfastened regardless of the shape of the shoelace.

Patent Registration No. 10-0144593 relates to a 'string hanger', and it is attached to an object such as a shoe and discloses a movement of a circular string using a support part such as a pulley and a roller. Because it uses the same shape as a pulley, only the string whose shape is close to a circle can be hung.

Utility Model Registration No. 20-0273549 relates to 'a shoelace ring with a roller', which also discloses fixing a roller such as a pulley to the shoelace ring, and the axis of the pulley is perpendicular to the upper. formed and tends to protrude high upwards.

As such, since the conventional string hook or shoelace ring uses a structure such as a pulley, the device inevitably protrudes from the upper to a predetermined height, and there is a problem that the external appearance is not good due to excessive protrusion.

The pulley method as in the prior art has a disadvantage in that it cannot be applied to the most commonly used flat band-shaped shoelaces because the shape of the available laces is limited only to those having a circular cross section.

The present invention can be applied to a flat shoelace in the shape of a band, and provides a shoe article in which the shoelace can be smoothly tightened and loosened.

The present invention provides a footwear article that can maintain a sense of fashion without appearing outwardly due to a thin thickness occupying the whole.

According to an exemplary embodiment of the present invention for achieving the above-described objects, the article of footwear including the upper includes at least one lace part mounted along an end of the upper and a shoe that passes through a through hole of the lace part. a lace, wherein the lace part includes a U-shaped fixing body mounted to the upper and a roller rotatably mounted to the opening of the fixing body, the axis of rotation of the roller being oriented parallel to the end of the upper.

Since the conventional pulley type roller has a rotation axis oriented in a direction perpendicular to the upper or its surface, it must protrude from the upper by at least the thickness of the roller, and cannot be applied to a thin and wide band-shaped shoelace. However, since the rollers of the above embodiments belong to the same plane that is not perpendicular to the upper or are provided along a parallel axis of rotation, they occupy a small thickness and do not protrude to the outside, and can be applied to a shoelace in a band shape.

The fact that the rollers are positioned parallel to or on the same layer as the upper may mean that the axis of rotation of the rollers is positioned on the same plane as the upper or arranged in parallel and flat adjacent to the upper.

The roller may form a through hole through which the shoelace passes by blocking the opening of the fixed body, and the roller may be formed to have a shorter average diameter compared to the length in the rotational axis direction.

According to an example, the U-shaped fixing body may be formed by two parts coupled to each other. For example, the fixed body may include a first quarter portion including a first rotation unevenness bound to one end of the roller and a second quarter portion including a second rotation unevenness bonded to the other end of the roller, As the first quarter part and the second quarter part are coupled, the roller may be rotatably mounted therebetween.

The first rotational unevenness and the second rotational unevenness may be formed in a protrusion or groove shape, and correspondingly, both ends of the roller may also be formed in a groove or projection shape.

The first rotational unevenness and the second rotational unevenness may be provided in a protrusion shape protruding in a mushroom shape, and a slit may be formed in the center of the projection-shaped rotational unevenness so that the projections are easily inserted into the grooves formed at both ends of the roller. .

A coupling protrusion may be formed on one side of the facing bonding surfaces where the first quarter part and the second quarter part are coupled and a coupling groove may be formed on the other side. can be provided in this way.

According to another example, the U-shaped fixing body is provided integrally, and a roller coupled thereto may be provided as two parts separated from each other or two parts connected by a hinge. In this case, the fixed body may be provided with rotating shafts extending from both sides or one side for rotation of the roller, and the rotating shafts may be interconnected or provided separately.

The roller may be formed in a shape extending long along the axis of rotation, and may be formed in a long ball shape, an hourglass shape, or a straight shape.

According to an exemplary embodiment of the present invention for achieving the above-described objects of the present invention, the lace part mounted to the article of footwear tightening the upper with a shoelace includes a U-shaped fixing body and a fixing body mounted on one end of the upper. It includes a roller rotatably mounted to the opening of the roller, the roller and the fixed body form a through hole through which the shoelace passes, and the axis of rotation of the roller may be oriented parallel to one end of the upper.

The fixed body may include a first quarter portion including a first rotation unevenness bound to one end of the roller and a second quarter portion including a second rotation unevenness bonded to the other end of the roller.

In the mutually coupled quarter parts, the first and second rotation irregularities are protrusions protruding in a mushroom shape, and a slit may be formed in the center, and one side of the facing junction surfaces where the first and second quarter parts are coupled. A coupling protrusion is formed in the coupling protrusion and a coupling groove may be formed on the other side.

In the footwear article of the present invention, the lace part may be easily mounted on the upper by various methods such as sewing, fusion, screwing, riveting, and the like, and as a standardized part, it may be mounted in various ways and in various colors of the upper.

The rollers are not only provided in small dimensions, but are arranged side by side on the upper to occupy a fairly small thickness, and can be applied to thin straps in the shape of a band, so that the shoelaces can be easily tightened and untied.

Here, the shoelace may be formed to be pulled from the left and right of the shoe article, but one end may be fixed and the other end may be tightened by pulling the other end.
