Definitions

• the present invention relates to a loose-preventable shoestring, and more particularly, to a loose-preventable shoestring that prevents shoestrings from coming untied due to movement of feet while a shoe wearer walks or runs.
• shoestrings which are tucked into shoes are divided into round strings that have a substantially round cross-section and flat strings that have a substantially rectangular cross-section.
• the round strings are manufactured by a braiding machine.
• one braiding machine produces only one thread at a time, such that its expected production per day is about 3 kg. Therefore, supply doesn't meet demand, and low production and high production cost lead to deterioration in price competitiveness.
• the flat strings are generally manufactured by a plain weaving machine.
• One plain weaving machine produces 8 to 12 threads at a time, such that its expected production per day is about 30 kg. Therefore, it shows an excellent supply capability and has low production cost. As a result, the plain weaving machine is much superior to the braiding machine in price competitiveness.
• the conventional shoestrings that are manufactured by means of the braiding machine and the plain weaving machine have a defect in that they come untied due to movement of feet as a shoe wearer walks or runs, and in that it is difficult to adjust the tension of the shoestrings to the point where the shoe wearer desires to have.
• the present invention has been made in view of the above problems, and it is an object of the present invention is to provide a loose- preventable shoestring that is manufactured by a plain weaving machine.
• a shoestring with tips fixedly pressed at both ends thereof including a plurality of woven tightening holes continuously provided at predetermined intervals thereon, wherein opposite tips of the shoestring are inserted into the tightening holes to form a shoestring knot.
• FIG. 1 is a perspective view of a shoestring according to the present invention
• FIG. 2 is an enlarged sectional view of a main part of the shoestring according to the present invention.
• FIG. 3 a to 3 f are top plan views illustrating a state in which the shoestring string is used, showing the steps of forming a shoestring knot. Best mode for Carrying Ont the Invention
• FIG. 1 is a perspective view of a shoestring according to the present invention
• FIG. 2 is an enlarged sectional view of a main part of the shoestring according to the present invention.
• a shoestring 1 is manufactured by means of a plain weaving machine which produces flat shoestrings.
• the shoestring 1 with tips 2 fixedly pressed at both ends includes a plurality of tightening holes 3 continuously provided at predeterniined intervals thereon.
• Each of the plurality of tightening holes 3 preferably has such a size as to permit one of the tips 2 to be passed therethrough.
• the intervals between the tightening holes 3 are adjustable but preferably set in a range between 5 mm and 10 mm.
• a reference numeral 4 denotes a shoe
• a reference numeral 5 denotes the upper part of the shoe.
• the preferred embodiment of the present invention is applicable to all kinds of footwear with shoestrings, and now, an explanation of the steps of forming a shoestring knot will be given in detail with reference to FIGs. 3 a to 3 f.
• the other tip of the tips 2 of the shoestring 1 is inserted into another tightening hole adjacent to the aforementioned tightening hole, such that the both ends of the shoestring 1 are crisscrossed in the shape of 'X', thereby forming a knot.
• the shoestring 1 maintains its knot with the help of the tightening holes 3, so that the shoestring 1 is prevented from becoming loose or untied even when the shoe wearer moves his or her feet.
• a loose-preventable shoestring 1 is provided with a plurality of tightening holes 3 that are disposed at predetermined intervals thereon. Tips 2 formed on both ends of the shoestring 1 are inserted through the tightening holes 3 to form a shoestring knot in the shape of 'X'.
• the shoe wearer since the plurality of tightening holes 3 are continuously formed, the shoe wearer can freely adjust the tension of the shoestring 1 according to his or her preference by just changing the positions of the tightening holes 3.
• the loose-preventable shoestring 1 according to the present invention can be made by means of a plain weaving machine at a relatively low production cost and also can exhibit a good supply capability. While the present invention has been described with reference to a few specific embodiments, the description is illustrative of the invention and is not to be construed as limiting the invention. Various modifications may occur to those skilled in the art without departing from the true spirit and scope of the invention as defined by the appended claims.
