The present inventors attempted to make a replica in order to make the design of the above-mentioned zipper come to a modern reproduction. However, the opening and closing of the chain that knew the structure at that time could not be smoothly carried out, and it was difficult to put it into practical use in the state of the structure at that time.

In the chain described in Patent Document 1, the connection or separation of the chain is achieved by inserting and removing the socket d ⁶ of the ring provided in one of the chains with respect to the core pin d ⁷ of the ring provided on the other chain. In the chain described in Patent Document 2, the connection or separation of the chain is achieved by the engagement or disengagement of the head of the plate chain a ² with the hook a ⁴ . In order to connect or separate the chain, it is necessary to expand the chain to a very large angle with the block connecting the positive back plates as a branch point (see FIG. 3 of Patent Document 1 and FIG. 3 of Patent Document 2).

However, it is inconvenient to operate to expand the chain at a large angle when joining or separating the chains. Moreover, when a chain is attached to a harder texture, or when the ends of the zipper are not separated, such as a luggage, the chain is hooked on the block when the slider slides. It is difficult to expand itself and thus expand itself.

Accordingly, it is an object of the present invention to provide a slider which inherits the design concept at the time and which can connect and separate a pair of chains with a smaller opening angle.

The present invention has been made in view of the above circumstances, and is a splicer for connecting and separating a pair of chains, comprising a slider body 41 and a support post 42 extending in the center of the upper end of the slider body 41.

By using the slider of the present invention, a pair of chains can be joined and separated at a smaller opening angle. Therefore, for example, a zipper with an initial design as a key can be provided with high practicality.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<1. Embodiment of the slider of the present invention>

In the present invention, the slider is slid so that the direction in which the pair of chains are coupled is the upper side, and the direction in which the pair of chains are separated is set to the lower side. Further, regarding each of the element rows, the side of the other element row of the opposing pair is referred to as the inner side, and the side opposite thereto is referred to as the outer side. In the front view of Fig. 2 and Fig. 5, the front side of the paper surface is referred to as the front side, and the back side of the paper surface is referred to as the back side (for example, the side of the slider including the tab attachment is the front side and the opposite side is the back side).

Fig. 1 is a perspective view showing a slider 40 according to an embodiment of the present invention viewed from below, and Fig. 2 is a front view, a plan view, a bottom view, and a cross-sectional view taken along line A-A of the slider 40 of the embodiment. Fig. 3 is a side view and a cross-sectional view taken along line B-B showing the slider 40 of the embodiment.

Referring to Fig. 1, the slider 40 includes a slider body 41 and a support post 42 extending from the center of the upper end of the slider body 41. The slider main body 41 has a basic function of a slider that connects and separates the pair of chains while being inserted. In addition to the basic function of supporting the slider main body 41 and ensuring its integrity, the support post 42 has a function of introducing a part of the chain in a separated state from the upper height to the slider main body 41 at the time of the connection of the chain, When the chain is separated, one of the chains in the joined state is taken out from the slider body 41 at a different height. Thereby, the introduction and withdrawal of the chain to the slider body 41 can be performed with a smaller opening angle.

Referring to FIGS. 2 and 3, the slider body 41 includes a front wing plate 43, a rear wing plate 44, side guide plates 46 that are erected on the left and right side edges of each of the front wing plate 43 and the rear wing plate 44, and a front wing plate. 43 and the guide wall 47 which is erected inside each of the back flaps 44, by which a curved groove or an arc-shaped groove is formed from the side of the engaging opening 48 to the side of the left and right introduction ports 49, thereby being internally A sprocket passage 50 having a substantially Y shape is formed.

1 , 2 and 3, the opposing side guides 46 and the guide walls 47 are vacant in the forward and reverse directions to be sufficient for the fastener elements to pass between the positive and negative flaps 43 and 44. 45 and leave. Thereby, the connection and separation operations can also be performed for a larger pair of chains that cannot be completely absorbed into the sprocket path 50.

As can be seen from the cross-sectional view taken along line B-B of Fig. 3, the element path 50 is preferably a flared type in which the width of the passage is gradually widened toward the left and right introduction ports 49 (upper end side) and the engagement port 48 (lower end side). Thereby, the constituent members of the chain such as the hook portion of the fastener element can smoothly enter and exit the slider main body 41.

Referring to FIG. 2, the support post 42 includes a first support plate 71 and a second support plate 72 extending from the center of the upper end of each of the front wing plate 43 and the rear wing plate 44, and a side edge from the first support plate 71 (in plan view) a first side wall 73 erected for the left side edge, and a second side wall 74 erected from the second support plate 72 at a side edge (the right side edge in plan view) opposite to the side edge on which the first side wall 73 is erected And a connecting plate 75 connecting the first side wall 73 and the second side wall 74 to the middle of the first supporting plate 71 and the second supporting plate 72.

As a result of the support column 42 having such a configuration, the chain constituting one of the pair of chains can pass through the first sprocket introduction path 81 divided by the first support plate 71, the first side wall 73, and the splicing plate 75. The other chain can be introduced into the path 82 by the second element which is divided by the second support plate 72, the second side wall 74 and the connecting plate 75. The first sprocket introduction path 81 and the second sprocket introduction path 82 are disposed at different heights, and if they are in the same plane, even when the expansion angle of each chain passes through the support column 42 with a small degree of mutual interference. The chains will not interfere. When the support column 42 is viewed from above, it is typically substantially zigzag as is apparent from the plan view of FIG. Of course, it is also possible to form a substantially inverted zigzag shape by exchanging the left and right sides of the first side wall 73 and the second side wall 74.

Referring to a cross-sectional view taken along line A-A of FIG. 2 and a side view of FIG. 3, in a preferred embodiment, the first side wall 73 and the second side wall 74 include inclined portions 83 and 84 toward the upper end side and the lower end side, respectively. Thereby, when the slider 40 is slid in the direction in which the pair of chains are coupled, the inclined portion 83 on the upper end side smoothly introduces the chain into the sprocket introduction paths 81 and 82, thereby causing the slider 40 to separate the pair of chains. The inclined portion 84 on the lower end side when the direction is slid causes the chain to smoothly introduce into the sprocket introduction paths 81, 82. The inclination angle of the inclined portions 83 and 84 is not particularly limited, and for example, it can be set to be 20 to 70° with respect to the plane on which the slider 40 slides.

Referring to the cross-sectional view taken along line B-B of Fig. 3, in the preferred embodiment, the upper end edge 85 and the lower end edge 86 of the connecting plate 75 are retracted into a concave shape. Thereby, when the inner side includes a case where the respective sprocket members constituting the pair of chains are engaged with the hook portions of the opposing sprocket, the passage of the hook portion is formed. As a result, the hook portion can be prevented from being caught on the connecting plate 75, and the sliding of the slider 40 can be smoothly performed.

Preferably, the pull tab mounting member 54 and the pull tab (not shown) attached thereto are mounted on the surface of the slider 40 to improve operability, for example, including the main flap 41 and the support post 42 as shown in FIG. And the pull tab mounting member 54 and the pull tab (not shown) connected thereto.

<2. Embodiment of the present invention for a chain>

Since the slider of the present invention includes the above-described configuration, each of the chains can be attached so as to be slidable while inserting the chain, and the chain can be connected to one of the chain rows connected by the connecting member. In one embodiment, each of the pair of chains includes an eyelet that is rotatably coupled to the coupling member and disposed above and below; and a hook that engages with a sprocket located at a lower portion of the opposing coupling member a head; a head that is engaged with a hook portion of a fastener element located at an upper portion of the opposing coupling member.

Hereinafter, a specific example of the chain 10 including one of the sliders 40 of the present invention will be described with reference to the drawings.

Fig. 4 is a perspective view showing a chain 10 according to an embodiment of the present invention, and Fig. 5 is a front view, a side view, and a cross-sectional view taken along line C-C showing the chain of the embodiment.

Referring to Fig. 4, in the chain 10 of the present embodiment, each of the chains 10A and 10B includes a row of the fastener elements 12 connected by the ring 11. In the chain of the present embodiment, the chain 10 includes a stop 13 for the sprocket 12 located at the lower end of each of the chains 10A and 10B, and a stop 14 above the upper end of the chain 10A. The slider 40 of the above embodiment is slidably inserted in the pair of chains 10.

Each of the chains 10A and 10B is formed by alternately arranging the sprocket 12 and the ring 11 of the same shape. In a state where the pair of chains 10 are coupled, each of the fastener elements 12 of one of the chains 10A faces the respective rings 11 of the other chain 10B, and the fastener elements 12 and the rings 11 of the pair of chains 10 are arranged in a zigzag shape.

Referring to Fig. 5, each of the fastener elements 12 includes a hook portion 15 provided in a hook shape on the inner edge, and a head portion 16 provided in a convex shape at the upper end. The hook portion 15 passes through the opposite ring 11 and is engaged with the head portion 16 of the sprocket 12 located at the lower portion thereof, and the head portion 16 is engaged with the hook portion 15 of the sprocket 12 located at the upper portion of the opposite ring 11. The hook portion 15 is preferably tapered so as to easily enter the hole of the ring. The hook portion 15 and the head portion 16 are not particularly limited as long as they can be engaged and opened. For example, the engagement portions of the hook portion 15 and the head portion 16 may be polygonal or formed by a line segment and a corner portion. Curved shape. In order to smoothly perform the engagement and opening operations of the two, it is preferable to use an arc-shaped curve as shown in FIGS. 4 and 5.

Each of the fastener elements 12 is rotatably coupled to the ring 11 by two holes 17 and 18 provided on the upper and lower sides. Further, the eyelets 17, 18 are provided at positions where the rings can be arranged in a straight line. The eyelets 17, 18 are threaded in the forward and reverse directions of the respective fastener elements. The lower eyelet 18 is a long hole shape in which the upper eyelet 17 extends toward the outer side of the fastener element 12. The lower eyelet 18 preferably extends obliquely upward, and may be, for example, a rectangular shape that extends obliquely upward toward the outside, a long hole shape that is curved upward, or a long hole shape in which two straight portions are formed. As shown in FIGS. 4 and 5, it is more preferable to extend outward so as to have an arc shape with the upper eye 17 as a central axis. Thereby, the hook portion 15 of each of the fastener elements 12 is easily rotated in the direction in which the head 16 of the sprocket 12 is open from the upper eyelet 17 as an axis, so that the chain 10 can be expanded even if the chain 10 is not enlarged. Engagement and opening operation of the hook portion 15 is performed.

The distance from the inner end to the outer end of the lower eyelet 18 (see the arrow x in the CC line cross-sectional view of FIG. 5) is set as the distance from the inner end to the outer end of the upper eyelet 17 (refer to the CC line cross-sectional view of FIG. 5). The arrow y) is 1.2 times or more, and more typically 1.2 to 3.0 times, for example, 1.4 to 2.0 times. In other respects, the distance from the inner end to the outer end of the lower eyelet 18 (see the arrow x in the CC line cross-sectional view of FIG. 5) is set to be the distance from the inner end to the outer end of the ring 11 (refer to FIG. 5). The arrow z) of the CC line cross-sectional view is 1.2 times or more, and more typically 1.4 to 3.0 times, for example, 1.4 to 2.0 times.

On the front and back surfaces of the sprocket 12, protrusions 19 extending in the vertical direction are provided between the holes 17, 18, and are arranged in a row with the ring 11. Since the protruding portion 19 and the ring 11 are narrower than the element tooth passage 50 in the slider 40 and can be accommodated in the element tooth passage 50, it is possible to guide the movement of each element tooth 12 in the element tooth passage 50.

The lower stopper 13 is a component that is provided to prevent the chains 10A, 10B from being completely separated. In the present embodiment, the lower stopper 13 is composed of a single component, and the lower stopper 13 cannot be separated from the left and right. Specifically, the lower stop 13 includes a plate 13A having an eyelet 24 for passing the ring 11, and is coupled to the sprocket 12 at the lower end of each of the chains 10A, 10B via the ring 11, respectively. At the upper end of the lower stop 13, a head portion 28 that engages with the hook portion 15 of the adjacent sprocket 12 is provided.

In other embodiments, the opening member 13' that can be detachably attached to the left and right can be used instead of the lower stop 13. For example, the first plate 13'A and the second plate 13 can be included as shown in FIG. The composition of 'B. Fig. 6 is a perspective view showing a state in which the respective plates viewed from the back side are separated. The first plate 13'A includes an eyelet 24'A through which the ring 11 passes, and is coupled to one of the chains 10A via the ring 11. Further, the second plate 13'B also includes an eyelet 24'B through which the ring 11 passes, and is coupled to the other chain 10B via the ring 11. A protrusion 21 is provided at a lower end of the first plate 13'A. A bottom plate 23 that reaches the lower end of the first plate 13'A is erected at a lower end of the second plate 13'B, and the protrusion portion 21 is fitted to the opening portion 22 provided in the bottom plate 23. At the upper end of the second plate 13'B, a head portion 28' that engages with the hook portion 15 of the adjacent sprocket 12 is provided. When the one chain 10A is coupled to the lower end of the other chain 10B, the projection 21 provided at the lower end of the first plate 13'A is fitted to the opening 22 of the bottom plate 23 provided on the second plate 13'B. . Thereby, even when the engagement of the pair of chains is completely open, the two chains can be prevented from being completely separated. Further, when one of the chains 10A is separated from the lower end of the other chain 10B, the lower end of the first plate 13'A is fitted to the opening 22 of the bottom plate 23 provided on the second plate 13'B. The protruding portion 21 is pulled out from the opening portion 22. Thereby, the two chains can be completely separated.

Referring to Fig. 5, the upper stopper 14 is a member provided to prevent the chains 10A, 10B from being joined to the above extent, and is attached to the upper end of one of the chains 10A so as to partially or completely block the hole of the ring 11. Thereby, the hook portion 15 of the sprocket 12 opposed to the ring 11 cannot pass through the ring 11, so that the connection of the chains 10A, 10B is prevented. As long as the upper stop 14 has this function, its shape is not limited, and for example, the eyelet 26 and the blocking plate 27 for passing the ring 11 may be included.

Mounting holes 20 may be provided in each of the fastener elements 12, and may be attached to various articles via a connecting member such as a ring or a string. In particular, it can be preferably attached to the opening and closing portion of the article. In the present embodiment, as can be seen from FIG. 4 and FIG. 5, the attachment hole 20 is provided in the outer edge of each of the fastener elements in the forward and reverse directions. In other embodiments, as shown in FIG. 7-1, a hook-shaped element 12' that can open and close the attachment hole 20 by the spring member 25 may be used. Here, the mounting hole 20 is provided to open in the up and down direction at the outer edge of the element, and the ring 29 can be mounted as shown in Fig. 7-2. Mounting holes 20, 20' may also be provided in the lower stop 13 or the opening member 13'.

In the present embodiment, the ring 11 that is not cut is used as the connecting member. However, the ring 11 is not limited as long as it can be engaged with the eyelets 15 and 16 of the fastener element 12. For example, as shown in FIG. 8, the connecting member may be a ring 53 provided with an inlet and outlet 51 so as to be detachable from the fastener element. Preferably, there is an overlap region 52 in contact with the joining member at the inlet and outlet 51 of the ring 53.

The material of the pair of chains 10 including the slider 40 is not particularly limited, and examples thereof include metals such as zinc alloy, silver, and brass, plastics, and ceramics.

The parts constituting the pair of chains 10 can be appropriately chamfered by C chamfering or R chamfering. For example, it is preferred that the hook portion 15 be chamfered to reduce hooking on the ring 11 or the slider 40. Preferably, the eyelets 17, 18 of the ring 11 or the sprocket 12 are also chamfered so that the sprocket 12 is smoothly rotated. Further, it is preferable that each portion of the slider 40 is also chamfered, and examples thereof include an upper edge 85 and a lower edge 86 of the connecting plate 75 which are in contact with the hook portion 15, and inclined portions 83 and 84.

As can be understood from the CC line cross-sectional view of Fig. 5, when the chains 10A, 10B are inserted into the element path 50 and the slider 40 is slid upward, the opposing elements 12 are engaged with each other and the chain 10A 10B is slowly linked. On the other hand, when the chains 10A and 10B slide the slider 40 downward, the opposing fastener elements 12 are opened and the chains 10A and 10B are gradually separated. As described above, by using the slider 40 of the present invention, the introduction and withdrawal of the chain to the slider body 41 can be performed at a narrower opening angle. Further, in the present embodiment, the chain 10 can be connected and separated at a small opening angle, so that the sliding of the slider 40 can be performed more smoothly.

<3. Industrial availability>

One of the chains of the present invention can be used, for example, as a necklace, a bracelet, a watchband, and the like, and other accessories. Moreover, by providing a mounting hole, it can be attached to various articles via a connecting member such as a ring or a string. Typically, it can be installed in the opening and closing parts of articles such as clothes, bags, shoes and groceries. Therefore, one of the present invention can be applied to various articles as a chain-opening opening and closing member. Since it is not necessary to sew the sewing machine, it is easier to remove and replace the article.

Fig. 9 is a schematic view showing an example of mounting of a chain to an article of the present invention. Here, an example will be described in which the chain 10 is attached to an opening and closing portion of the article including the buttonhole 60 symmetrically at the same distance from the attachment hole 20 of the pair of chains 10 in one embodiment of the present invention. As described above, in the present embodiment, the fastener elements 12 in the chain 10 are arranged in a zigzag shape. Therefore, for one chain 10A, the buttonhole 60 of the article is located directly beside the mounting hole 20 of the chain, whereas the buttonhole 60 of the article is located at the oblique direction of the mounting hole 20 of the chain for the other chain 10B. Therefore, for example, for one of the chains 10A, the comb 10 can be passed through the grommets 60 of the next or upper section after the shackle 60 is passed back to the same grommets 60 by the cords 61 of the mounting holes 20 on the side. For the other chain 10B, it is assumed that the cord 61 is alternately passed through the corrugated knot of the grommets 60 and the mounting holes 20.

The embodiments of the present invention have been described above with reference to the drawings, but the present invention is not limited to the embodiments, and various modifications can be made.
