Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a synthetic resin lace fastener used for equipment such as anoracks, backpacks, shopping bags, and life vests that require tight laces.

BACKGROUND TECHNOLOGY This type of lace fastening device generally includes a main body that is integrally formed with a front plate and a back plate and a side plate and has a narrow opening and a wide opening, and a main body that has a long groove formed in the top plate. One is known that consists of a slider that slides inside the main body along a sliding groove and tightens the string between it and the side plate (Japanese Patent Publication No. 48-4511, Utility Model Publication No. 52-52)
Publication No. 648).

Problems to be Solved by the Invention However, when the string to be inserted into the main body is thick, there is a problem in that it becomes difficult to insert the string through any of the openings.

The present invention has been made with the above-mentioned points in mind, and it is an object of the present invention to provide a lace fastener that allows the lace to be easily passed through the main body.

Means for Solving the Problems According to the present invention, the above-mentioned problems are solved by providing a string fastener in which a pair of left and right string insertion holes are formed in the front plate or the back plate of the main body.

Embodiments Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a lace fastener according to the present invention, and the lace fastener 1 has a main body 2.
and a slider 3 that is housed within the main body 2 and slides within the main body 2.

As shown in FIG. 2, the main body 2 has a top plate 4 and a back plate 5 integrally connected by side plates 6, 6 to form a cavity, and as shown in FIG. It has a narrow opening 7 and a wide opening 8. Each side plate 6 has a vertical portion 6a and an inclined portion 6b. The top plate 4 is formed with an elongated sliding groove 9 in which the slider 3 slides, and a pair of string insertion holes 10 and 1 through which the string C is inserted on the left and right sides of the sliding groove 9.
0 is formed. Each string insertion hole 10, 10
has large diameter holes 11, 11 at vertically separated positions,
The slit 12 is narrower than the string C that communicates the two holes 11, 11. Numeral 13 is a step-like jagged surface formed adjacent to the vertical portion 6a on the inner surface side of the inclined portion 6b of the side plates 6, 6, and increases the tightening force of the string C. Note that the string insertion holes 10, 10 may be provided in the back plate 5.

As shown in FIGS. 2 and 4, the slider 3 includes a circular stopper 14 as a tightening body for tightening the string C between the slider 3 and the main body 2, and a top plate 4 of the main body 2. It consists of a knob part 15 that protrudes from the surface through a sliding groove 9, and an uneven part 16 is formed on the knob part 15 to improve the grip of fingers. As shown in FIG. 4, locking portions 17, 17, which are step-like uneven surfaces, are formed on both side circumferential surfaces of the stopper 14 above and below the center line l in the horizontal axis direction. When the string C is held between the slider 3 and the side plates 6, 6 of the main body 2, the locking portions 17, 17 are designed to sink into the string C and prevent the string C from coming off.

FIG. 4 shows a state in which the string C is inserted through the string tightener 1, and by sliding the slider 3 in the direction of the arrow A, the inner surfaces of the side plates 6, 6 of the main body 2 and the stopper 14 are engaged. The string C is held between the stop parts 17 and 17 and tightened. At this time, since the jagged surfaces 13, 13 are formed on the inner surfaces of the side plates 6, 6, the tightening force on the strands C increases, which is preferable.

Function Next, to explain how to use the lace fastener 1 according to the present invention, first, as shown in FIG. The strings are passed through the large diameter holes 11, 11 from the inside, respectively, and the ends of the strings are made to come out from the main body 2. At this time, if each hole 11, 11 is made oval, it will be easier to pass the string C through. Then, when both ends are grasped with fingers and pulled in the direction of the arrow, the center part of the string between the two ends passes through the slit 12, and the string C is easily inserted into the main body 2. The inserted string cannot easily come out of the main body 2 because the slit 12 is narrow.

Effects of the invention As described above, according to the invention, the string insertion hole, which consists of two large-diameter holes spaced apart in the front plate or back plate of the string tightener body, and a slit that communicates the two holes, is made symmetrical. Since I formed a pair of
Even if it is a relatively thick string that is difficult to insert through the opening of the string tightener, it has a practical effect in that the string can be easily inserted with a simple structure.
