Each of the above-described string fasteners has a small number of members, and locks a tightening string arranged on an article to be applied such as clothes using a relative displacement of each through hole, and also uses an operation string to Since the member can be moved in the inward direction of the female member and the pull-out amount of the tightening string can be adjusted, it is simple and easy to use.

However, the structures of

Patent Documents

1 and 2 are not versatile because they cannot be easily replaced once the operation cord is assembled. In addition, the operation cord of Patent Document 1 is thickened as a double cord because it bypasses the engagement hole provided in the male member from the lower through hole of the female member from one side to the other. Properties are easily lost. Since the operation cord of Patent Document 2 must be fixed to the lower end portion of the male member by a method such as adhesion or insert, workability is poor and it is difficult to reduce manufacturing costs.

Therefore, the object of the present invention is to solve the above-mentioned problems, and in particular, to make it possible to easily incorporate an operating string or to easily replace it so as to be excellent in fashionability. Other purposes will be clarified in the description below.

In order to solve the above-described problems, the present invention provides a female member having a through-hole in the periphery, a male member having a through-hole in the periphery and movably fitted in the female member, and the male member as described above. An urging means for urging in a direction protruding from the female member, and an operation led out through a through hole provided in the lower end portion of the female member in a state where the upper end side of the string is locked to the male member A string fastener that is capable of moving in the direction in which the female member is retracted against the urging force by the pulling force of the operating string, wherein the male member has the through hole An inner space provided on the lower side and penetrating to the periphery, and a through-hole formed through the inner space and the lower end surface so as to penetrate the female member and a substantially coaxial line; In a state where the upper end side of the operating string is inserted into the inner space through the through holes of the female member and the male member It is characterized by being locked.

The above-mentioned present invention is more preferably embodied as follows.
(A) the male member has an opening larger than the through hole provided in the lower periphery of the through hole and communicating with the inner space, and the operation string is extended from the inner space. It is a structure that is led out through the opening and can form a bulging portion for retaining the knot or the like. Note that the bulging portion for retaining is preferable because the knot is simple, but a technically simple stopper or the like may be used. In this aspect of (a), since the male member has an opening larger than the through hole communicating with the inner space, the operating string is once led out from the inner space through the opening, After forming the bulging portion for retaining the knot or the like, the operation string can be assembled or replaced more quickly by pulling.
(A) The male member has a locking claw protruding around the lower side of the through hole, and the female member is engaged with the through hole of the female member in a state where the locking claw is fitted into the through hole. It is the structure which prevents omission. In this aspect of (a), since the locking claw is prevented from coming off from the female member in a state of being fitted into the through hole of the female member, even if the fastening string is not inserted into each through hole as a string fastener, Can be handled as a single piece.

(C) The female member has a string insertion mounting groove provided around the upper side. In the aspect (c), the string fastener can be attached to the article to be applied so that the attachment string is inserted into the attachment groove to form a loop.
(D) The through hole of the female member is configured to be larger than the through hole and the opening of the male member. In this aspect (d), since the through hole of the female member is formed larger than the through hole and the opening of the male member, the operation string is opened from the inner space and passed through the large through hole on the female member side. It is suitable for an operation to be led out into the inner space and an operation for accommodating the bulging portion for retaining the knot or the like in the inner space again after forming.

In the present invention, when assembling or exchanging the operating string, for example, the male member is inserted from the through hole of the female member through the through hole of the male member into the inner space of the male member, and a bulging portion such as a knot is formed at the inserted end portion. Can be easily assembled, and the operation string can be made a single string compared to Patent Document 1, for example, to make it easier to suppress the outer diameter of the string fastener, When placed in the bag, it can be led out from the inside of the bag through a hole or eyelet. By these, this invention can improve fashionability from points, such as the incorporating property of an operation string, exchange property, and a single string structure, and can contribute to application expansion.

The (structure) form string fastener 4 comprises a male spring 1 and a female member 2 and a coil spring 3 and an operating string 6 as urging means. Of these, the male member 1 and the female member 2 are both resin molded products, but other than the resin may be used. The coil spring 3 is made of metal, but may be made of resin. The overall size is enlarged on the drawing, but it is actually quite small. Details are as follows.

First, as shown in FIGS. 1A and 1B and FIGS. 7A to 7E, the male member 1 is a cylindrical portion 10 that is long in the axial direction. The tube portion 10 is provided so as to face the periphery of the upper side (this is a case where the tube portion 10 is oriented vertically, and when it is turned sideways, the left end or the right end is one end side, hereinafter the same). Two through-

holes

11, 11, two openings 12 a that are provided opposite to each other at a predetermined distance below each through-hole 11 and communicate with the inner space 12 of the cylindrical portion, and each through-hole 11 and each Two locking claws 13 projecting opposite to the periphery between the opening 12a, the lower end portion 14 formed to be slightly smaller in diameter, and the inner space 12 and the lower end surface of the lower end portion 14 are formed through therethrough. And a lower through-hole 16.

The outer periphery of the cylinder part 10 is continuous with the same diameter except for the respective locking claws 13 and the lower end part 14. The inside of the cylindrical portion 10 has a substantially the same hole diameter up to a little above the lower end portion 14, that is, the upper through hole 15 and the inner space 12 are continuous holes having the same diameter, and the lower through hole 16 is slightly smaller in diameter. ing. The through hole 16 is set to a hole diameter through which the operation cord 6 is inserted with a margin.

Each through hole 11 is a rectangular hole as shown in FIGS. 5 (a) and 5 (b), but may be a hole having a size that allows the target fastening strap 5 to be inserted with a margin. The inner space 12 is on the string upper end side of the operation string 6 (this is the same as the above-mentioned cylinder portion 10 when it is vertically oriented, and when it is horizontally oriented, it is the one end side that is the left end or the right end, hereinafter the same). The knot 6a, which is a bulging portion for preventing slippage, is formed.

Each opening 12a has a rectangular shape that is slightly larger than the through hole 11, but may have any shape as long as it can be inserted with sufficient margin through a bulging portion for preventing slipping such as a knot 6a provided on the operation cord 6. Each latching claw 13 is a protrusion, and the protrusion dimension is substantially the same as the outer diameter of the female member side cylindrical portion 20 as shown in FIGS. The lower end portion 14 is a portion that fits and supports one end (upper end in the drawing) side of the coil spring 3.

As shown in FIGS. 1A and 1B and FIGS. 6A to 6D, the female member 2 is a substantially tunnel-shaped tube that forms in the inner space 25 from the upper side to the vicinity of the lower end. It is part 20. The cylindrical portion 20 has two through-

holes

21 and 21 provided to face the periphery of the intermediate portion, a mounting portion 22 that protrudes in a bowl shape from a part of the upper periphery, and FIGS. ) And a lower through hole 26 that penetrates the inner space 25 and the lower end surface.

The inner space 25 is sized to accommodate almost the entire male member 1. Each through hole 21 has a substantially rectangular shape that is long in the longitudinal direction of the cylinder, and has a size that is substantially the same as or slightly larger than the opening area of the male member side through hole 11 and the opening 12a. The attachment portion 22 is penetrated in the longitudinal direction of the top and bottom or the tube portion 20 to form an attachment groove 23. As illustrated in FIG. 5A, the attachment string 7 is incorporated into the attachment groove 23 in a state of being inserted in a loop shape. The attachment string 7 is used when attaching the string fastener 4 to an article to be applied such as clothes as necessary.

3A and 3B, in the assembled state in which the male member 1 is inserted into the female member side inner space 25, the spring support portion 24 is a coil spring between the lower end portion 14 on the female member side. This is a place where 3 is supported in a freely expandable / contractible manner. The through hole 26 is formed to have substantially the same diameter as the through hole 16 on the male member side and faces the through hole 16, and the corresponding end side of the operation cord 6 can be inserted from here toward the through hole 16. To. The coil spring 3 has a coil diameter larger than the outer diameter of the spring support portion 24 and the lower end portion 14 and smaller than the inner diameter of the female member side inner space 25.

(Assembly) Each of the above members is assembled as a string fastener 4 in the following manner. First, the coil spring 3 is fitted and supported at one end by the spring support portion 24 as shown in FIG. From this state, the male member 1 is inserted into the cylinder of the female member 2. In the insertion operation, each locking claw 13 hits the upper end edge of the cylindrical portion 20 while the male member 1 is being inserted into the female member side cylindrical portion 20, but each locking claw 13 is pressed inward to reduce the diameter. By being deformed in the direction, it is finally fitted into the corresponding through hole 21 while being pushed into the cylindrical portion 20. As a result of the fitting, the male member 1 is assembled to the female member 2 in a state of being prevented from coming off as shown in FIG. 3A, and the urging force of the coil spring 3 maximizes the female member 2 (the locking claw 13 is the female member). The through hole 11 is moved to the upper side from the through hole 21 on the female member side. This assembly is a string fastener 4 having a three-point configuration.

Moreover, the above string fastener 4 becomes the string fastener 4 of 4 points | pieces by attaching the operation string 6 to the male member 1 so that attachment or detachment or replacement | exchange is possible as shown in FIG.3 (b). That is, the string fastener 4 is provided with the string 6 in a mode in which the operation string 6 is not assembled, or is provided in a mode in which the operation string 6 is assembled. In the former case, it may be possible to provide a plurality of sets of different colors or patterns as the strings 6, and the user selects the desired string 6 and attaches it to the string fastener 4 later. In this operation, for example, one end side of the string 6 is inserted from the female member side through hole 26 into the male member side through hole 16 and the inner space 12 as shown in FIG. The knot 6a is formed by being pulled out through the side through hole 21. Thereafter, when the other end of the cord 6 (the other end is provided with a bulging portion such as a knot 6a or other stopper) is pulled in the direction of the arrow in FIG. 3B, the formed knot 6a is passed through the hole. 21 and the opening 12a are pulled into the inner space 12 to form a string fastener 4 having a four-point configuration.

(Usage example) The above-described four-point string fastener 4 has an arbitrary length at both ends or one end of the string 5 disposed around the opening edge of clothes or a bag-like member, as in

Patent Documents

1 and 2. It is used when engaging with the strap or adjusting the pull-out amount and the tightening degree of the tightening string 5. That is, in the relationship with the tightening string 5, as illustrated in FIG. 3B, the operating string 6 is pulled in the direction of the arrow in the figure, or FIGS. 8A, 8B, 9A, and 9B are used. ), The male member 1 is resisted against the urging force of the coil spring 3 by applying tension in the direction of the arrow by the method described above or by directly pushing the male member 1 into the cylinder of the female member 2. From the state in which both the through

holes

11 and 21 of the male member 1 and the female member 2 are substantially aligned, the corresponding ends of the tightening cord 5 are inserted into the respective through holes. Thereafter, the pulling and tension of the operation string 6 described above is released, and the pushing force on the male member 1 is released. Then, the male member 1 is moved upward by the urging force of the coil spring 3 with respect to the female member 2, whereby the through hole 11 is displaced relative to the female member side through hole 21, and the fastening string 5 is predetermined. It will be prevented from coming off by the tension (string locked state). The string fastener 4 has the following superior functions and effects in addition to the above basic functions.

(1) The string fastener 4 can easily replace the operation string 6 according to the user's preference or the like. That is, in the exchange operation of the operation string 6, in the example of FIGS. 3A and 3B, the string 6 is slightly lifted upward from the state of FIG. 3B, and the knot 6a as shown in FIG. Is pulled out from the opening 12a and the through hole 21, the knot 6a is loosened or cut, and then the string 6 is detached from the string fastener 4 simply by pulling the other end. As described above, the new string 6 for operation is inserted into the through hole 16 and the inner space 12 from the through hole 26 as shown in FIG. 3A, and from the inner space 12 to the opening 12a and the through hole 21. And is pulled out to form a knot 6a. Thereafter, when the other end of the string 6 is pulled in the direction of the arrow in FIG. 3B, the knot 6a is pulled into the inner space 12 from the through hole 21 and the opening 12a.

(2) The string fastener 4 is not only easy to replace the operation string 6 as described above, but also has a single string structure compared to the double string structure as in Patent Document 1, It becomes easy to keep the outer diameter dimension small, and the degree of freedom of design can be expanded. Moreover, even if the string fastener 4 is arranged in the bag-like portion 81 as in the use examples shown in FIGS. 4 (a) to 4 (c), the operation string 6 is provided with a hole in place of the eyelet 9 or eyelet from the bag. It can be derived to the outside through good looks.

Supplementary explanation of Fig. 4 (a)-(c). Reference numeral 8 is assumed to be a winter hood or similar. 4B and 4C, the hood 8 has an elongated bag-like portion 80 provided along the peripheral edge of the opening, and is provided on both sides of the bag-like portion 80 so as to open the bag-like portion 80 side. A bag-like portion 81 for the strap fastener 4 and two eyelets 9 which are located in the bag-like portion 81 and are attached to the surface material at a predetermined interval. Reference numeral 83 denotes a sewing portion for forming the bag-like portion 81.

The fastening strap 5 is inserted into the bag-like portion 80. The corresponding end side of the fastening string 5 is put into the bag-shaped part 81 from the bag-shaped part 80, and the through

holes

21 and 11 and the eyelet of the string fastener 4 arranged in the bag-shaped part 81 as shown in FIG. 9 is pulled out from the back side of the hood 8 to the front side. A knot 5a and other bulging portions for retaining are provided at the end of the strap 5 as required. Further, the operation string 6 of the string fastener 4 is drawn from the back side of the hood 8 to the front side through another eyelet 9. 4 (a)-(c), the procedure for adjusting the pull-out amount and the tightening degree of the tightening string 5 is as follows. Pull or loosen only the required amount.

(3) FIGS. 5 (a) and 5 (b) show the relationship between the string fastener 4 and the hood 8 as an article to be applied in the usage example of FIGS. 4 (a) to 4 (c). 5A, the attachment cord 7 inserted into the attachment groove 23 is in the bag-like portion 81 and attached to the hood 8 side by the sewing portion 7a. Similar to Patent

Documents

1 and 2, this configuration is achieved by fixing the position of the string fastener 4 to the article to be applied via the attachment string 7 by the sewing portion 7a and the like, and the female member due to the pulling force of the operation string 6 This is because the male member 1 moves efficiently with respect to 2. On the other hand, the string fastener 4 shown in FIG. 5B is simply put in the bag-like portion 81 without using the attachment string 7 and is loosely fitted. Even in this case, when the operation string 6 is pulled, the female member 2 hits the eyelet 9 and the position of the above-described string fastener 4 is restricted. become. This action is because the operation string 6 of the string fastener 4 has a single string configuration and can use the eyelet 9.

In addition, the above form does not restrict | limit this invention. The present invention only needs to substantially include technical elements specified in the claims, and the details can be variously changed and developed as necessary. As an example, the urging means is to integrally form an elastic piece or a similar elastic portion on a male member or a female member instead of a coil spring.
It should be noted that the entire contents of the specification, claims, drawings and abstract of Japanese Patent Application No. 2011-252222 filed on November 18, 2011 are cited herein as disclosure of the specification of the present invention. Incorporate.
