  Each of the above-described strap fasteners has a small number of members, and is locked to the straps arranged on the use members such as clothes and bag-like members through the respective through holes, so that the pull-out amount of the straps can be easily adjusted. Although it is simple and easy to use, it was still not satisfactory from the following points.

(A) In the conventional structure, since the biasing means is disposed between the bottom surface side of the male member and the inner bottom surface side of the female member, it is difficult to reduce the size or weight. For example, in the state where the string is locked between the lower edge of the male member side through hole and the upper edge of the female member side through hole, the full size of the female member is the bottom side of the male member and the female member. This is because an arrangement space for the biasing means must be secured between the inner bottom surface side.

(A) In the conventional structure, as a mounting means for mounting on a member to be used, a male thread of Patent Document 1, a sewn piece part of Patent Document 2, a slit configuration for mounting a mounting band or the like in addition thereto is employed. However, they lacked versatility and were easily restricted in use.

  An object of the present invention is to solve the above-described problems, particularly to improve the appearance characteristics and facilitate downsizing, thereby contributing to improvement of reliability and expansion of applications.

The invention of claim 1 includes a female member having a through hole in the periphery thereof, a male member having a through hole in the periphery thereof and slidably fitted in the female member, and the male member as the female member. And a biasing means for biasing in a direction protruding from the female member , the female member and the male member are each formed in a cylindrical shape penetrating in the axial direction, and the female member has both end portions. The male member has a mounting plate that is detachably connected to the end of the male member that does not protrude and is attached to a use member such as a garment or bag, and the biasing means is disposed around the male member. It consists of a coil spring to be arranged, and one end is locked to a large diameter portion provided on the protruding end side of the male member, and the other end is locked to a stepped portion provided on the inner periphery of the female member. It is characterized by that.

Further, in the above inventions, the female member has a plurality of engaging projections projecting from the upper inner circumference than the through-hole, in a state where said engaging projection is fitted into the through hole of the male member It is preferable to prevent the male member from coming off.

  In the first aspect of the present invention, since the coil spring as the biasing means is disposed around the male member, it is secured between the bottom surface side of the male member, that is, the inner bottom surface side of the female member as in the conventional structure. The arrangement space for the biasing means is not required, and the entire size is shortened accordingly, which can contribute to further miniaturization and weight reduction.

At the same time, in the invention of this, as attachment means for use member such as clothes or bag-like member, of both end portions of the female member has a mounting plate that is detachably connected to an end portion does not project the male member Therefore, compared with the conventional attachment means, the presence or absence of the attachment plate can be selected, the attachment plate is attached in advance to the member to be used, the string fastener can be connected later, and the appearance in a mode that does not require the attachment plate Easy to maintain. In addition, in the present invention, when the female member has a cylindrical shape penetrating in the axial direction, it is easy to form an attachment / detachment with respect to the attachment plate, that is, an engagement portion corresponding to the engagement portion of the attachment plate as in the embodiment. It is also excellent in terms of good operability.

In the invention of claim 2, since the female member prevents the male member from coming off via the locking projection, the assembly of the female member and the male member is maintained even before the string is passed through each through hole. For this reason, in the case of Claim 1 and 2, it becomes possible to maintain the handleability of a string fastener favorably.

  The best mode of the present invention will be described with reference to the drawings. 1 and 4 show a string fastener with a mounting plate, FIGS. 2 and 3 show a string fastener without the mounting plate, FIG. 5 shows a usage state of each string fastener, and FIG. 6 shows a string fastener. The male member single item which comprises the fastener is shown, and FIG. 7 has shown the female member single item which comprises the string fastener. In the following description, detailed description will be given in the order of outline, structural feature, and action feature.

(Summary) The string fastener 3 of the form example includes a male member 1 and a female member 2 and a coil spring 15 (referred to as a three-point configuration when particularly distinguished from the latter), a male member 1 and a female member. There is an aspect (referred to as a four-point configuration when particularly distinguished from the former) composed of two aligned coil springs 15 and a mounting plate 16. That is, the cord fastener 3 having the three-point configuration and the four-point configuration differs depending on whether or not the mounting plate 16 is an essential component, and the male member 1 and the female member 2 and the coil spring 15 are the same member. Therefore, in the following description, after the common points of both are described, the mounting plate 16 is referred to.

  2 and 3 illustrate the three-point string fastener 3, and FIGS. 1 and 4 illustrate the four-point string fastener 3. FIG. Further, the male member 1, the female member 2, and the mounting plate 16 are all resin molded products, but they may be other than resin. The coil spring 15 is made of metal. The overall size is enlarged on the drawing, but it is actually quite small.

(Structural Features) Among the structural members of the string fastener 3, the male member 1 has a tubular shape that is entirely penetrated in the axial direction as shown in FIG. 2 or FIG. 4 and FIG. Two sets (four in total) of through-holes 11 provided in a state of being penetrated in the radial direction, a large-diameter portion 12 provided around the upper end (projecting end) side, and provided around the lower end side The taper portion 13 is integrally provided with a diameter that decreases toward the bottom.

  Here, the through-hole 11 is a through-hole having a size that allows a string to be inserted with a margin as in the conventional case, and it is sufficient that there is at least one set. The large diameter portion 12 is set to have the maximum diameter substantially the same as the outer diameter of the female member 1, and is substantially flush with the outer diameter of the female member 2 when the cylindrical portion 10 is inserted into the female member 2 to the maximum. It becomes a state. A concave groove portion 14 is provided around the lower end surface of the large diameter portion 12. The groove portion 14 is a place where one end (the upper end in the figure) side of the coil spring 15 is accommodated.

  As shown in FIG. 2 or FIG. 4 and FIG. 6, the female member 2 has a cylindrical shape that is penetrated in the axial direction, and is provided in a state of being penetrated in the radial direction of the cylindrical portion 20. Two sets (four in total) of through-holes 21, a stepped portion 22 provided on the inner periphery on the upper end side of the cylindrical portion 20, a locking portion 25 provided on the inner periphery on the lower end side of the cylindrical portion 20, and a cylinder A plurality of locking projections 24 projecting from the inner periphery of the portion 20 are integrally provided.

  Here, the cylinder part 20 has a diameter that allows the male member side cylinder part 10 to be slidably received. The length is set so that the male member 1 can be inserted into the cylindrical portion 20 until the large-diameter portion 12 hits the upper end surface of the cylindrical portion 20, but the urging means is the bottom surface side of the male member and the female member. Compared to the conventional female member arranged between the inner bottom surface side, only the arrangement space of the urging means is reduced. Each through hole 21 is a through hole having substantially the same size as the through hole 11 of the male member 1. Although the number of the through holes 21 is configured in two sets, it is sufficient that at least one set is provided as in the case of the through holes 11.

  The step portion 22 is formed by forming the inner periphery on the upper end side of the cylindrical portion 20 to have an inner diameter slightly larger than the inner diameter of the cylindrical portion. The inner end surface of the stepped portion 22 is a place where the other end (lower end in the figure) side of the coil spring 15 is received. The locking portion 25 is formed on an end surface where the lower end of the cylindrical portion 20 is bent toward the inner diameter side, and the vertical section is convex or claw-shaped. The locking portion 25 acts as a lower end treatment for improving the appearance of the lower end of the female member 2 in the case of the three-point configuration of the string fastener 3, and engages the attachment plate 16 in the case of the four-point configuration of the string fastener 3. It will be a place to stop. The locking projection 24 is provided on the inner periphery of the cylindrical portion 20 so as to approach the stepped portion 22 and directly above each through hole 21. For this reason, a total of four locking protrusions 24 are provided, and the male member 1 protrudes into the corresponding through hole 11 on the male member side in a state where the male member 1 is inserted into the cylindrical portion 20. It regulates so that it may not remove from female member side cylinder part 20 carelessly.

  The coil spring 15 is arranged with a fine gap in the outer diameter of the male member side cylindrical portion 10 (cylindrical portion excluding the large diameter portion 12), and the coil diameter is larger than the outer diameter of the cylindrical portion 10, and It is smaller than the inner diameter of the female member side step portion 22.

  The coil spring 15 described above is disposed on the outer diameter of the male member side cylinder portion 10 so that one end of the coil spring 15 is engaged with the groove portion 14. Thereafter, the male member 1 is inserted into the cylinder of the female member 2 together with the coil spring 15. In the insertion operation, the corresponding portion hits the locking projection 24 on the female member side while the male member 1 is being inserted. For example, by tilting the male member 1, each locking projection 24 corresponds to the tapered portion 13. It is made to fit in the through hole 11 to be performed. As a result of the fitting, the male member 1 is assembled to the female member 2 and is maximally engaged with the female member 2 by the urging force of the coil spring 15 (the locking projection 24 is engaged with the lower portion of the through hole 11 on the male member side). The through hole 11 is moved to the upper side of the through hole 21 on the female member side. This assembly is a string fastener 3 having a three-point configuration.

  Moreover, the above string fastener 3 becomes the string fastener 3 of 4 points | pieces by attaching the attachment plate 16 to the female member 2 so that attachment or detachment is possible. The mounting plate 16 is a circular welding thin plate, and integrally includes an engaging portion 17 protruding from the center portion. The engaging portion 17 has a substantially U-shaped vertical cross section, and is detachably engaged with the female member side locking portion 25. Of course, the mounting plate 16 may have a shape other than a circle, and the engagement shape with the locking portion 25 is arbitrary. Further, the mounting plate 16 may be configured to be mounted on a mounted portion of a member to be used such as clothes or a bag by bonding or sewing instead of welding.

(Functional Features) The above-described three-point string fastener 3 or the four-point string fastener has an arbitrary end or one end of the string M arranged around the opening edge of clothes or a bag-like member, for example. It can be locked to the length, and the pull-out amount and tightening degree of the M string can be adjusted. That is, in the relationship with the string M, as illustrated in FIG. 5, the male member 1 is pressed against the female member 2 against the urging force of the coil spring 15, and the through holes 11 of the female member 2 and the male member 1 are From the state in which 21 are almost aligned, the corresponding ends of the strings M (both ends of the same string or corresponding ends of different strings) are inserted into the through holes 11 and 21, respectively. Thereafter, the pressing force of the male member 1 is released. Then, the male member 1 enters a protruding state with respect to the female member 2 by the biasing force of the coil spring 15, and the relative position of the through hole 11 with respect to the female member side through hole 21 is shifted, and the string M is held at a predetermined tension. It will be prevented from coming off (string locked state). Each string fastener 3 has the following superior functions and effects in addition to the above basic functions.

(1) Since the male member 1 and the female member 2 are both penetrated in the axial direction in the three-point string fastening device 3 as an attaching method to the used member (clothes, bag-like member, etc.), for example, FIG. As illustrated in (a), the suspension member N is passed through each cylinder of the male / female members 1 and 2, and both ends or one end of the suspension member N (for example, the other end is connected to one side). Can be attached to the use member in a suspended state. In the case of the string fastener 3 having a four-point configuration, it can be attached in the same manner by removing the attachment plate 16 from the female member 2.

(2) The novelty and appearance can be maintained for a long time in a state of being attached to the member to be used. This is because the conventional string fastener is difficult to get out once dust or dust enters the female member through the hole, so that it tends to accumulate gradually, and the hygiene and appearance deteriorate. On the other hand, in the string fastener 3 having the above three-point configuration, since the male and female members 1 and 2 penetrate in the axial direction, it is difficult for dust and dirt to collect in the female member 2 as in the past. Even if it adheres to the cylinder, it can be easily removed. Since the female member 2 is detachably attached to the mounting plate 16 in the four-point string fastener 3, even if dust or dirt adheres to the inside of the cylinder, it is removed from the mounting plate 16 and has a three-point configuration. It can be easily removed in the same manner as the string fastener 3.

(3) Each of the three-point and four-point string fasteners 3 can be made smaller and lighter than conventional string fasteners, thereby contributing to the expansion of applications. This is because the coil spring 15 is arranged around the male member-side cylindrical portion 10, so that the arrangement space for the urging means between the bottom surface side of the male member and the inner bottom surface side of the female member in the conventional structure becomes unnecessary. It is.

(4) Since the string fastener 3 having the four-point configuration has the mounting plate 16 that is detachably connected to the end of the female member 2, the mounting operability can be improved as compared with the conventional mounting means. In addition, it is possible to improve the appearance characteristics while reducing the cost by making the plate shape more suitable for use members such as clothes and bag-like members. As for the mounting operability, for example, the mounting plate 16 is attached to the use member side in a state where it is detached from the string fastener 3 (female member 2), and then the strap is attached to the mounting plate 16 attached to the use member side. This is because the tool 3 (female member 2) can be attached through the engagement of the locking portion 25 and the engaging portion 17. As for the appearance characteristics, for example, the three-point string fastener 3 is commonly used, and only the mounting plate 16 is changed to a shape and size suitable for the used member, so that the manufacturing cost can be reduced for each used member. This is because it is possible to make a special product.

In addition, the above form does not restrict | limit this invention. The present invention only needs to substantially include the technical elements specified in claims 1 and 2 , and the details can be variously changed and expanded as necessary.
