As shown in Fig. 14, in this slider 100, a holding rod 110 with a head has a disk 110 interposed between the head 110 and the slider body 108. Then, the slider penetrates the mounting hole 104 formed through the guide post 106 of the body 108. The disk 110 has a pair of cutouts 112 at positions diametrically opposed on the peripheral surface. Two linearly arranged pivots 114 of the puller 116 are fitted in the respective cutouts 112 of the disk 110. Next, the lower end of the holding rod 102 is fixed to the lower surface of the slider body 108. As a result, the handle 1 16 can swing and rotate on the slider body 108.

In recent years, in the luggage industry, guarantees of product life have been screaming. If the slide fastener attached to the bag is damaged, it is desired that the slide fastener restore its function. The slide fastener component that is most likely to be damaged during use is slider 100. The cause of slider 100 damage is: The slider 1 16 of the slider 100 is caught by an external object during its reciprocating motion, which causes excessive twisting and pulling between the slider 1 16 and the slider body 1 08. As a result, the pivots 114 and 114 of the puller 116 are damaged, and the puller 116 falls off or the slider body 108 is deformed. Conventionally, once the slider 100 has been damaged, the user must remove the damaged slider 100 from the slide fastener attached to the bag and re-attach a new slider to the slide fastener. did not become. However, this repair work had the problem of spending a lot of time, effort and money.

Further, in the conventional slider 100, the puller 116 can be swung in the vertical direction and can rotate at an angle of 360 degrees in the horizontal direction of the slider body 108. Even if the puller 1 16 is subjected to severe pulling or twisting when using the handle 100, the force between the puller 1 16 and the slider body 1.08 is reduced, and the puller 1 1 6 had the advantage that there was no danger of resisting torsional or pulling forces. However, once the pivot 114 of the puller 116 was damaged, the entire broken slider 100 had to be removed from the fastener chain and replaced with a new slider. These replacements were time consuming and costly.

Therefore, an object of the present invention is that even if a load such as severe twisting or tension is applied to the handle, the handle can swing in the vertical direction and rotate in the horizontal direction of the slider body. This load is relieved, the slider operates smoothly, and even if the handle breaks, the slider does not need to be removed entirely from the fastener chain, and only the damaged handle is removed. The purpose is to provide a slider for a slide fastener that can be easily replaced with a new handle.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 4 show a slider 1A for a slide fastener according to a first embodiment of the present invention. As shown in FIG. 1, this slider 1A is composed of the following five members: a slider body 2, a locking member 3, a holding rod 4, a puller 5, and a washer 47. The slider body 2 is formed from a metal such as a zinc alloy or an aluminum alloy by die casting. The slider body 3 comprises a pair of upper and lower wing plates 9 and 10 connected at their front ends by guide columns 8. Each side edge of the upper wing plate 9 and the lower wing plate 10 is fastened through a slider. A pair of guide flanges 11 are provided for guiding the row of nut elements. The outer sides of the upper wing plate 9 and the lower wing plate 10 protrude at their respective front ends to form disc-shaped ridges. At a position extending through the guide column 8, a mounting hole 12 is formed through the center of the disk-shaped ridge of the upper blade 9 and the lower blade 10. As shown in FIG. 4, the mounting hole 12 has an upper large-diameter hole 17, a lower small-diameter hole 18, and an enlarged-diameter recess formed outside the lower wing 10. It consists of one and three.

The locking member 3 is injection-molded using a thermoplastic resin such as polyacetal, polyamide, polypropylene, and polybutylene terephthalate. As is well shown in FIGS. 1 and 3, the locking member 3 has a substantially disk shape. The locking member 3 has an inner annular portion 21 having a circular through hole 20 formed at the center thereof, and an outer annular portion concentrically arranged outside the inner annular portion 21 outside the inner annular portion 21. It comprises an arcuate leg 22 and a connecting portion 26 for coupling the inner annular portion 21 to the center of the outer arcuate leg 22. A pair of cutouts 23 and 23 are formed at positions on the circumferential surface of the outer arcuate leg 22 opposite to the diametrical direction, thereby providing a locking portion 23. In other words, the locking portion 23 is provided in the form of a notch 24 formed at a position diametrically opposed to the outer arcuate leg 22. The locking member 3 can be elastically deformed. In particular, since the outer arc-shaped leg 22 is elastically attached to the connecting portion 26, a pair of pivots 4 of the puller 5 described in detail below will be described. 2 can be easily fitted into the locking member 23 of the locking member 3 by the elastic deformation of the outer circular leg portion 22 of the locking member 3.

The holding rod 4 is made of metal, and includes a cylindrical pin 31 and a disk-shaped head 30 provided at one end thereof. The outer diameter of the disk-shaped head 30 is substantially the same as the outer diameter of the locking member 3. The pin 31 has a diameter allowed to pass through the through hole 20 of the locking member 3. The pin 31 includes an upper large-diameter portion 32 formed next to the disk-shaped head 30 and a lower small-diameter portion 33 formed next to the upper large-diameter portion 32. .

A washer 47 is interposed between the locking member 3 and the slider body 2 so that the locking member 3 can easily rotate with respect to the slider body 2.

The handle is made of metal, like the slider body 2. The handle 5 is composed of a knob 43 formed at one end in an appropriate shape, and an arc-shaped recessed portion 44 formed at the other end, whereby the recessed portion 44 is formed. A pair of opposing arms 44a are provided on the 两 side. Inside each of the opposing arms 44a, a pair of linear pivots 42 are provided so as to protrude toward each other. Since the locking member 3 has elasticity, when the handle 5 is pressed against the locking portion 3 so that the pivot 42 of the pulling member comes into contact with the peripheral surface of the locking portion 3, The respective pivots 42 are formed by elastic deformation of the elastic arc-shaped legs 22, and each of the locking portions 2 3 formed on the elastic arc-shaped legs 22 of the locking member 3 capable of rotating 360 °. , 23 locked. As a result, the tab 5 can be turned on the slider body 2 by an angle of 360 degrees in the horizontal direction. Furthermore, since the concave notch 4 4 of the puller 5 substantially matches the outer shape of the head 30 of the holding rod 4, the puller 5 swings about the shaft 42 in the vertical direction of the puller 5. I do.

Since the slider 1A is configured as described above, the slider 1A is assembled in the following order. First, the pin 31 of the holding rod 4 is inserted through the through hole 20 of the locking portion 3 and then through the pusher 47. And finally, it is inserted through the mounting hole 12 of the slider body 2. The terminal end of the pin 31 projecting beyond the mounting hole 12 is crushed and fixed to the recess 13. The pivots 42 of the tabs 5 are formed by the elastic deformation of the locking members 3, more specifically, by utilizing the elasticity of the arcuate legs 22 of the locking members 3, and The engaging portions 23 are snap-engaged with each other. Therefore, the puller 5 is pivotable on the locking member 3 rotatably attached to the holding rod 5. The slider 1A is assembled. When the holding rod 4 is attached to the slider body 2, the circular head 30 of the holding rod 4 completely covers the locking member 3 including the locking parts 23, 23. As a result, the opposing pivots 42 of the tab 5 are prevented from deviating from the engagement relationship with the locking portion 23 of the locking member 3.

As shown in FIGS. 5 to 8, the structure of the locking member 3 can be variously modified. The locking member 3a of the first modification shown in FIG. 5 is similar to the locking member 3 according to the preceding embodiment, but differs in the following points. That is, in FIG. 5, instead of the single outer arcuate leg 22, a pair of outer arcuate legs 22 are formed by the respective connecting portions 26 in the diameter direction of the inner annular portion 21. It is connected to the opposing position. As a result, the outer arc-shaped legs 22 are arranged in a diametrically opposed relationship with each other, and the two diametrically opposed notched recesses 2 are provided between the legs 22. 5 is formed. The two notches 25 constitute the locking portion 23. The two legs 22 and 22 are elastic and flexible.

The locking member 3b of the second modified example shown in FIG. 6 is a metal disc 29, and a through hole 20 is formed in the center thereof. Two pairs of upstanding projections 28 are cut and raised by stamping the metal disk, and each pair is arranged at a position diametrically opposed to the other pair. Each pair of protruding pieces 28 are arranged to face each other, forming a recess 24 therebetween. Then, the two opposing concave portions 24 constitute the locking portion 23. In the case of the locking member 3b, the pivot 42 of the puller 5 shown in FIG. 13 is used. Then, the pivot 42 of the handle 5 is engaged with the locking portion 23 by elastic deformation.

The locking member 3c of the third modified example shown in FIG. 7 is a disk 29 made of metal or resin. The circular plate 29 has a circular through hole 20 formed in the center, is formed in a wavy shape, and two peaks are formed with a concave portion 24 interposed therebetween. The recess 24 extends across the through hole 20. And this variant In the above, the concave portion 24 forms the locking portion 23. When attaching the handle 5 to the locking member 3, the pivot 42 of the handle 5 presses the ridge of the disk 29 downward, whereby the pivot 42 of the handle 5 crosses the ridge. Thus, it engages with the concave portion 24, that is, the locking portion 23 by elastic deformation.

The locking member 3d of the fourth modified example shown in FIG. 8 is a rubber disc 29. A pair of flat portions 24 are formed at positions on the outer peripheral surface of the disk 29 opposite to each other in the diameter direction. The concave portion 24 forms the locking portion 23. When attaching the puller 5 to the locking member 3, the pivot 42 of the puller 5 presses the peripheral surface of the rubber disc 29, whereby the pivot 42 of the puller 5 becomes a rubber circle. When at least one of the plate 29 and the locking member 3 d is elastically deformed, it engages with the concave portion 24, that is, the locking portion 23.
