The present invention relates generally to an eyeleted string fastener for use in articles, such as clothing, bags, and shoes, and more particularly to a structure that combines the functions of a button and a string fastener to secure a string with a narrowed slot to thereby achieve the advantages of excellent structural stability, easy installation, and low manufacturing cost.
Referring to
The string fastener 80 is often structured to include a first component 81 and a second component 82 having a portion received in the first component 81. The first component 81 and the second component 82 comprise string holes that are communicateable with each other and the first component 81 and the second component 82 are structured to be movable with respect to each other by arranging an elastic device therein so that the string 91 is movable to extend through the string holes of the first component 81 and the second component 82, whereby with a pressure applied by the second component 82 caused by the elasticity, after a pressing down force is removed, the elastic force causes the circumferences of the string holes to pinch and thus fasten the string 91 received through the string holes.
Thus, it can be known from the above description that after the string fastener 80 and the string 91 are combined together, since the string fastener 80 is exposed outside clothing, a bag, or a shoe surface and is not properly positioned and fixed on the surface of the article, it is quite possible to inadvertently contact and press the string fastener 80 so as to cause undesired skidding or even vibrating, skewing, and thus loosening resulting from undesired pulling and stretching, thereby leading to poor stability of the entire structure and limiting the functionality and performance of the operation thereof. Further, the string fastener 80 has a certain amount of volume and if mounted to a lower hem of clothing, would causes discomfort of a user when the user is sitting down and unexpectedly contacting the rigid object like string fastener 80.
Further, the structure of the string fastener 80 is composed of the first component 81, the second component 82, and the elastic device arranged therein. A number of components is used, making assembly thereof tedious and difficult and also increasing the manufacturing cost thereof.
Further, a riveted grommet 92 is often mounted to a through hole of the clothing 90 where the string 91 extends in order to protect the circumference of the hole. This further increases the number of the constituent components and thus heightens the manufacturing cost.
Thus, the structure of the conventional string fastener is generally imperfect and the present invention aims to provide a technical solution that overcomes the drawbacks of the prior art.
To cope with such problems, the present applicant has proposed, in Taiwan Patent No. 102212821, a fastener structure that comprises a flat fastener. The fastener has a surface in which at least one hollowed portion is formed. A narrowed slot is formed in at least a corner of the hollowed portion to be in communication with the hollowed portion, whereby the narrowed slot may pinch and thus fasten a string. However, such a structure of string fastener cannot be effectively attached, through riveting, to a piece of fabric, so that a metallic material or a fiber reinforced plastic material must be included for riveting and thus attaching to the fabric in order to achieve secure coupling thereof with the fabric of an article, such as clothing, a bag, or a shoe.
Thus, the present invention aims to provide a structure of an eyeleted string fastener to overcome or alleviate the above-discussed issues and problems.
An object of the present invention is to provide a structure of eyeleted string fastener that combines the functions and structures of a riveted grommet and a string fastener, where an arrangement of a narrowed slot is provided for pinching and fastening a string to achieve the advantages of having excellent structural stability, being easy to mount, and having a low manufacturing cost.
To achieve the above object, the present invention provides an eyeleted string fastener that comprises a button base and a fastener. The button base has a bottom on which a hollow fitting cylinder is formed. The fitting cylinder has a top rim that is expanded outward to form a stop ring. The stop ring has an outer circumferential edge from which a circumferential wall extends upward so as to form forms therein a receiving compartment. The fastener is receivable in the receiving compartment of the button base and has a surface having a circumferential rim portion forming a pressing section that is depressible by and riveted by a top edge of the circumferential wall of the button base to coupled to the button base or alternatively be depressed down by a surface lid to be riveted and fixed. The fastener comprises a hollowed portion formed inboard and surrounded by the pressing section. The hollowed portion has a side in which a narrowed slot is formed in such a way that the narrowed slot is in direct communication with the hollowed portion or is alternatively formed horizontally in a projection block that is located beside the hollowed portion at a side thereof that is opposite to the hollowed portion. As such, the eyeleted string fastener can be mounted to an article, such as clothing, a bag, or a shoe, through the fitting cylinder of the button base with a string extending through the fitting cylinder to be received in the hollowed portion of the fastener and, after adjustment of the length thereof, being forcibly fit into the narrowed slot thereby allowing the string to be securely pinched and fixed by the narrowed slot. As such, the issue of structural instability of the conventional string fastener that is readily skidding, vibrating, skewing, and loosening and the problem of being difficult to assemble and high manufacturing cost can all be overcome.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.
