BRIEF DESCRIPTION OF THE DRAWINGS A preferred embodiment of the present invention will be described with reference to the accompanying drawings in which: FIG. 1 and FIG. 2 show the form of a cord strap fastener not wearing the cord, and the third figure shows an example of the strap for assembly operation. The fourth, fifth and fifth figures show the use of a strap fastener, the sixth diagram shows a single female component, and the seventh diagram shows a single male component. The following is described in detail in the order of construction, assembly, and use cases:

(structure)

The cord buckle 4 of the present embodiment is composed of a male member 1 and a female member 2, a coil spring (elastic member) 3 as an energizing member, and an operation cord 6 . Among them, both the male member 1 and the female member 2 are synthetic resin molded articles, but they are not made of materials other than resins. The coil spring 3 is basically made of metal, but it is also indispensable if it is formed of a resin. The overall size of the clip 4 is enlarged in several times for ease of understanding, but it is actually quite small. The detailed configuration is as follows: The male member 1 integrally forms a long tubular portion 10 extending in the axial direction as shown in the first and seventh figures. The cylindrical portion 10 has a peripheral end portion (this is a case where the cylindrical portion 10 is longitudinally upright, and if it is placed laterally, it is one end portion of the left end or the right end thereof, the same applies hereinafter), and the peripheral wall is diametrically opposed and connected. The two lateral ports 11, 11 of the inner cavity 12 of the tubular portion are disposed under the respective distances of the respective ports 11 and the side peripheral walls are also opposite and open to the two openings 12a, 12a of the inner cavity 12 of the cylindrical portion. The peripheral wall between each of the ports 11 and each of the openings 12a is a relatively outwardly projecting claw 13 formed at the lower end, and the lower end is formed with a diameter-reducing lower end portion 14 that penetrates the upper end surface and communicates with the upper end of the inner cavity 12 through the hole 15 And passing through the lower end surface of the lower end portion 14 to communicate with the through hole 16 at the lower end of the inner cavity 12.

On the outer circumference of the tubular portion 10, in addition to each of the locking claws 13 and the reduced diameter lower end portion 14, a continuous cylindrical wall of the same diameter is formed, and the inner cavity of the cylindrical portion 10 is slightly upward from the lower end portion 14 to the upper end portion. Approximately forming the same aperture, in other words, on The end through hole 15 and the inner cavity 12 form a continuous through hole of the same diameter, and only the lower end through hole 16 forms a smaller aperture. The through hole 16 has an aperture sufficient for the operation cord 6 to be easily passed through.

Each of the ports 11 is formed as a rectangular opening as shown in Fig. 5, but is not limited thereto, as long as the beam mouth (or the tightening) of the tolerant object is easily pierced by the string 5. The inner cavity 12 has a foot that can easily accommodate the upper end portion of the operating cord 6 (that is, when the finger cylinder 10 is placed in a longitudinally upright position as in the front, if it is placed in a horizontally lying position, it is the right end or Either end of the left end.) The size of the knot 6a formed to prevent the head from expanding.

Each of the openings 12a is formed with a rectangular opening larger than the upper opening 11, and the shape and size thereof can be such that the knot 6a of the operation cord 6 can be prevented from being loosened and the head can be easily passed. Each of the locking claws 13 forms a projection projecting in the radial direction, and the protruding dimension is substantially the same as the outer diameter of the tubular portion 20 of the female member 2 as shown in the third figure. The lower end portion 14 is formed with a spring seat for fitting one end (illustrated as an upper end) of the coil spring 3.

As shown in the first and sixth figures, the female member 2 forms a cylindrical portion 20 having a hollow inner cavity 25 from the upper end to the lower end and having a shape slightly resembling a tunnel shape. The tubular portion 20 has two rectangular lateral openings 21, 21 which are disposed on the peripheral wall of the central portion of the intermediate portion, and are provided with a plurality of rectangular lateral openings 21, 21 protruding from the peripheral wall side of the upper end portion, as shown in the third figure. The spring seat 24 on the inner side of the bottom and the through hole 26 passing through the lower end of the inner cavity 25 and the lower end surface (bottom).

The inner cavity 25 is formed to be large enough to accommodate the size of the entire male member 1. Each of the openings 21 forms a slightly rectangular opening extending along the longitudinal direction of the tubular portion 20, and is approximately the size of the opening 11a of the opening 11 of the male member 1. The opening area is the same size. The mounting portion 22 is formed with a through hole 23 for inserting through the longitudinal direction of the tubular portion 20 as a mounting slot. The slot 23 has a mounting strap as shown in FIG. 5(a). 7 rewinds into a loop for installation and fixing. The mounting belt 7 can be used to attach the cord buckle 4 to an object to be applied such as clothes, a backpack, or the like as necessary.

Further, as shown in the third figure, in a state where the male member 1 is assembled to the inner cavity 25 of the female member 2, the spring seat 24 is formed between the spring seat 24 and the lower end portion 14 of the male member 1. The support space for the elastically expandable support coil spring 3. The through holes 26 are formed to have substantially the same diameter as the through holes 16 of the male member 1 and face each other vertically, and the corresponding ends of the operation cords 6 can be inserted into the through holes 16 from the through holes 26 through the hollow portions of the coil springs 3. Further, the inner diameter of the coil spring 3 is larger than the outer diameters of the spring seat 24 and the lower end portion 14, and the outer diameter is smaller than the inner diameter of the inner cavity 25 of the female member 2.

(assembly)

The above components are assembled into a complete cord buckle 4 according to the following methods. First, one end of the coil spring 3 is inserted into the spring seat 24 as shown in FIG. 6(d), and in this state, the male member 1 is slightly biased from above into the tubular portion 20 of the female member 2. When the male member 1 is inserted into the interior of the female member 2, the locking claws 13 first touch the upper edge of the tubular portion 20, but the lower end faces of the locking claws 13 are chamfered. The wedge-shaped surface has a hollow opening relationship between the upper and lower sides thereof, and the locking claw 13 is inserted into the pressing force to be radially inwardly contracted and deformed, and can be smoothly inserted into the cylindrical portion 20 and finally assembled into the inner cavity of the female member 2. At the same time, the lower end portion 14 is also embedded in the upper end of the coil spring 3. At this time, as soon as the pressing operation force is released, the male member 1 is as shown in the third figure (a), and is pushed up by the coil spring 3 to make the card The claws 13 are locked to the female member 2 to constitute a detachment prevention state, and the assembly is completed. Thus, the male member 1 is pushed up by the spring 3 to protrude upwardly above the highest position of the female member 2 (ie, the locking claw 13 is locked at the position of the upper edge of the opening of the opening 21 of the female member 2), so that the opening 11 is displaced. A staggered position is formed above the opening 21 of the female member 2. This assembly is always a cord buckle 4 consisting of only three components and can be used directly.

As shown in the third figure (b), the cord buckle 4 having the above structure is a cord buckle which is composed of four members when the operation cord 6 detachable or replaceable for the male member 1 is attached. 4. This configuration is more convenient in use because the operation cord 6 can be pulled to replace the direct pressing of the protruding end of the male member 1. In other words, the present invention can provide a cord for unattached operation 6 or as an accessory, and the cord 6 can be used for use, or the cord buckle 4 of the state in which the cord 6 is installed first is available for the user to select. use. In the former case, a variety of ropes 6 of different colors, patterns or materials can also be prepared for the user to freely choose, that is, to select the favorite rope. The belt 6 is assembled after use in the male fastener 1 for use. According to this assembly operation, for example, as shown in the third diagram (a), one end of the cord 6 is inserted into the inner cavity 12 from the through hole 26 of the female member 2 through the through hole 21 of the male member 1, thereby the inner cavity 12 then pulls the outside through the opening 12a and the opening 21 of the female member 2, and after giving the knot 6a, the other end of the strap 6 (this end can also be preceded by a knot 6a or a stop As shown in the third figure (b), the extension head is pulled in the direction of the arrow, and the knot 6a is inserted into the inner cavity 12 through the through opening 21 and the opening 12a and is locked to the male member 1. The hole edge above the through hole 26 is formed as a cord buckle 4 composed of four members.

(use case)

A cord buckle 4 composed of four members, like a conventional clip such as Patent Document 1 or 2, can be used to fasten a string of a loop at the periphery of an opening such as a garment, a bag or a bag. The position of any length or end of the 5 ends, and the tension of the pull-out length or opening of the bundled strap 5 is adjusted. Specifically, the relationship between the cord buckle 4 and the harness strap 5 is as shown in the third diagram (b), and the operating strap 6 can be pulled in the direction of the arrow of the figure, or like the eighth figure and the ninth. The pulling operation belt is shown, or the male member 1 is directly pressed into the inner cavity of the female member 2 from above to force the male member 1 to sink below the inner portion of the female member 2 against the elastic pushing force of the coil spring 3. The male member 1 and the two-ports 11, 21 of the female member 2 are substantially overlapped and communicated. For example, if the bundled strap 5 has been worn beforehand, the length of the strap 5 and the opening degree of the beam opening can be adjusted; for example, a cord 5 If not worn, one end of the bundle cord 5 can be inserted into the cord buckle 4 to be buckled and integrated. Subsequently, the pulling force of the operating cord 6 can be released as previously shown to relieve the pressure under the male member 1, and the male member 1 is springed back up to the upper side of the female member 2 by the force of the spring 3, due to the harness strap 5 There is a fact that the port 11 and the opening 21 of the female member 2 are in a positionally staggered position, and the bundled strap 5 can be pressed and twisted and locked to maintain the tensile effect within the predetermined tension.

In addition to the above basic functions and effects, the cord buckle 4 of the present invention has the following excellent effects that conventional products never have:

(1) The cord buckle 4, the assembled operation cord 6 can be easily replaced by the user's personal preference. Specifically, the replacement operation of the operating cord 6 is In the example of the third figure, the cord 6 can be lifted from the bottom to the top from the state of the same figure (b), and then, as shown in the figure (a), the knot 6a is self-overlapping the opening 12a and After the opening 21 is pulled out of the outside and the knot 6a is unwound or cut, the other end of the strap is pulled to pull the strap 6 out of the clip 4. The new operation cord 6 is further inserted into the inner cavity 12 through the through holes 26 and 16 as shown in the figure (a), and then through the opening 12a and the opening from the inner cavity 12, according to the assembly method described above. 21 Pulling out the outside, it is convenient to make a knot 6a, after which the other end of the strap 6 is pulled in the direction of the arrow shown in the figure (b), and the knot 6a is externally connected through the opening 21 and the opening 12a. It is pulled into the inner cavity 12.

(2) In addition to the above-described advantages of the simple replacement of the operating cord 6, the cord buckle 4 is easier to control the outer diameter of the entire fastener as compared with the two-strand cord of Patent Document 1 because of the structure of a single cord. The size, and thus the degree of freedom in design, and, as in the use example shown in FIG. 4, when the strap fastener 4 is disposed in the pocket portion 81, the strap 6 can also be passed from the pocket via the buttonhole 9 or The eyelet is aesthetically pleasing and pulled out of the exterior for use.

Supplementary explanation will be given to the fourth figure: the symbol 8 is a hood which is assumed to be a cold-proof jacket or the like, and the hood 8 is provided with an elongated tubular shape along the periphery of the opening 8a as shown in Figs. (b) and (c). The portion 80, and the cord holder 4 for receiving the end portion of the tubular portion 80 facing the tubular portion 80, and the pocket portion 81 for receiving the cord, and the inside of the pocket portion 81 (also the surface of the head cover 8) are fixed. Two buttonholes at intervals 9. Reference numeral 83 is a sewn portion for sewing the pocket portion 81 to the inner surface of the head cover 8.

The bundled strap 5 is passed through the tubular portion 80, and the two ends are respectively pulled out from the end nozzle of the tubular portion 80 and then placed in the pocket portion 81, and as shown in Fig. (c), the through opening 21 of the cord buckle 4 is inserted. After the 11 and the buttonhole 9, the surface is pulled out from the inside of the head cover 8, and the end of the string is attached with a knot 5a or other components to form an anti-off-expanding head. Further, the operating cord 6 of the clip 4 is pulled out from the inside of the head cover 8 through the other buttonhole 9 to pull out the surface. In the fourth figure, the length of the pull-out of the bundled strap 5 or the adjustment of the tightness of the bundle mouth In the same manner as the above-described basic action, the pull-out end of the bundled loop 5 can be pulled out or loosened in the state in which the operation cord 6 is pulled down.

(3) The fifth figure shows the relationship between the cord buckle 4 and the use of the hood of the applicable object in the use example of the fourth figure. The cord buckle 4 of the same figure (a) is sewn to the inside of the pocket portion 81 of the head cover 8 by the attachment belt 7 around the mounting slot 23. According to this, the cord buckle 4 can be positioned on the object to be applied by the mounting belt 7 by the sewn portion 7a or other means, so that when the operating cord 6 is pulled, the male member 1 can react immediately with respect to the positioning mother. Component 2 operates effectively. As for the cord buckle 4 of the same drawing (b), the attachment belt 7 is not used and is directly inserted into the pocket portion 81, but when the operation cord 6 is pulled, the entire fastener 4 is pulled to cause the female member 2 to be moved. One end touches the grommet 9, that is, it is blocked and no longer moves, and then the male member 1 can move relative to the female member 2. The concealed use of such a matching pocket enables the surface of the object to be applied to be simple and aesthetically pleasing.

Furthermore, the embodiments described above are for illustrative purposes only and are not intended to limit the invention. The present invention may be provided as long as it has the technical features specified in the scope of the patent application, and various modifications or extensions may be made as necessary for the details. The coil spring of the energy member (elastic member) may be replaced by an elastic piece integrally formed on the male member or the female member or the like having the same function.
