US Pat. No. 557,207 British Patent No. 6998

The present inventor tried to produce a reprinted version in order to revive the design at the time when the above slide fastener was born. However, it was found that the chain with the structure at that time could not be opened and closed smoothly, and it was difficult to put it into practice with the structure at that time.

In the chain described in Patent Document 1, the connection or separation of the chain is achieved by inserting / removing the socket d ⁶ provided in the link of one chain with respect to the pintle d ⁷ provided in the link of the other chain. In the chain described in Patent Document 2, connection or separation of the chain is achieved by engagement or disengagement of the head of the plate link a ² and the hook a ⁴ . In any case, in order to connect and separate the chain, it is necessary to expand the chain at a considerably large angle inside the slider (see FIG. 3 of Patent Document 1 and FIG. 3 of Patent Document 2).

However, it is inconvenient in operation that it is necessary to expand the chain at such a large angle when connecting or disconnecting the chain. In addition, when the chain is attached to a hard fabric, or in the case of a stop product in which both ends of the fastener are not separated, such as a bag, it is difficult to expand the chain itself.

Therefore, an object of the present invention is to provide a pair of chains, particularly a slide fastener chain, which can be connected and separated with a smaller expansion angle while inheriting the design concept of the time.

The present invention was created in view of the above circumstances, and in one aspect,
A pair of chains that can be engaged and disengaged, each chain comprising a row of elements connected by a connecting member;
Each element has a hook portion, a head portion, and a pivot hole that is pivotally connected to the connecting member and is provided above and below, where the hook portion is in the lower stage of the opposing connecting member. Engaged with the head of the element, the head is engaged with the hook of the element on the upper stage of the opposing connecting member,
The lower eye hole is in the shape of a long hole extending outside the element as compared to the upper eye hole.
A pair of chains.

In one embodiment of the chain according to the present invention, the lower eye hole extends outward in an obliquely upward direction.

In another embodiment, the chain according to the present invention includes an element passage inside, and includes a slider that allows the chain to be connected and separated by sliding while inserting the row of elements.

In yet another embodiment, the chain according to the present invention further includes an opening or bottom stop connected to the element at the lower end of each chain by a connecting member.

In yet another embodiment of the chain according to the present invention, the opening device or the bottom stop has a head portion that is engaged with a hook portion of an adjacent element.

In another embodiment of the chain according to the present invention, the opening device has a first portion connected to one chain by a connecting member, and a second portion connected to the other chain by a connecting member. The first part and the second part are configured to be detachable.

In yet another embodiment of the chain according to the present invention, each element has an attachment hole for attaching to the opening / closing part of the article via a connecting member.

In another aspect, the present invention is an article in which a pair of chains according to the present invention is attached to an opening / closing part via a connecting member.

In one embodiment, an article according to the present invention has an opening / closing portion having left and right symmetry at the same interval as the pitch of the mounting holes of the pair of chains according to the present invention. Return the string that passed through the mounting hole to the same eyelet again, and then make a comb-like knot that passes the string through one lower or upper eyelet, and for the other chain, place the string in the eyelet and the mounting hole. A pair of chains according to the present invention is attached by forming a wave-like knot that alternately passes through.

According to the present invention, it is possible to provide a chain that can be connected and separated with a small expansion angle by increasing the degree of freedom of movement of the element. Therefore, for example, it is possible to provide a fastener with a design based on the early days as a motif with high practicality.

<1. First Embodiment>
FIG. 1 is a perspective view showing a pair of chains 10 according to the first embodiment of the present invention, and FIG. 2 is a front view and a side view showing the chains according to the first embodiment. The figure and the AA line sectional view are shown.

Referring to FIG. 1, a pair of chains 10 according to the first embodiment includes a row of elements 12 in which the chains 10 A and 10 B are connected by a ring 11. The pair of chains 10 according to this embodiment includes an opening 13 connected to the element 12 at the lower end of each

chain

10A, 10B by a ring 11 and an upper stopper 14 at the upper end of one chain 10A. .

In each

chain

10A, 10B, elements 12 and rings 11 having the same shape are alternately arranged. In a state where the pair of chains 10 are connected, each element 12 of one chain 10A faces each ring 11 of the other chain 10B. In the pair of chains 10, both the element 12 and the ring 11 are arranged in a zigzag shape. The

Referring to FIG. 2, each element 12 has a hook portion 15 provided in a hook shape at the inner edge and a head portion 16 provided in a convex shape at the upper end. The hook portion 15 passes through the opposing ring 11 and is engaged with the head portion 16 of the element 12 at the lower stage, and the head portion 16 is engaged with the hook portion 15 of the element 12 at the upper stage of the opposing ring 11. The hook portion 15 is preferably tapered so that it can easily enter the hole of the ring. The shape of the hook portion 15 and the head portion 16 is not particularly limited as long as the engagement / release operation of both is possible. For example, a polygonal shape or a curved shape in which both engagement portions are formed by line segments and corner portions. It can be made into the shape which becomes. In order to smoothly engage and disengage both, it is preferable to use an arcuate curve as shown in FIGS.

Each element 12 is rotatably connected to the ring 11 by two eye holes 17 and 18 provided at the top and bottom. The eye holes 17 and 18 are provided at positions where the rings can be arranged in a straight line. The eye holes 17 and 18 are respectively drilled in the front and back direction of the element. The lower eye hole 18 has a long hole shape that extends to the outside of the element 12 compared to the upper eye hole 17. The lower eye hole 18 preferably extends obliquely upward, for example, a rectangular shape extending obliquely upward to the outside, a long hole shape curved upward, or a long hole shape in which two straight portions are formed. be able to. As shown in FIGS. 1 and 2, it is more preferable to extend outward in an arc shape with the upper eye hole 17 as a central axis. As a result, the hook portion 15 of each element 12 can be easily rotated about the upper eye hole 17 in the direction to be released from the head 16 of the opposing element 12, and the entire chain 10 is greatly expanded. Even if it is not opened, the hook portion 15 can be engaged and released.

The distance from the inner end to the outer end of the lower eye hole 18 (see arrow x in the cross-sectional view taken along the line AA in FIG. 2) is the distance from the inner end to the outer end of the upper eye hole 17 (AA in FIG. 2). It is typically 1.2 times or more with respect to the arrow y in the cross-sectional view), more typically 1.2 to 3.0 times, for example, 1.4 to It can be 2.0 times. In another aspect, the distance from the inner end to the outer end of the lower eye hole 18 (see the arrow x in the cross-sectional view along the line AA in FIG. 2) is the distance from the inner end to the outer end of the ring 11 (A in FIG. 2). It is typically 1.2 times or more with respect to the arrow z in the cross-sectional view of line A), and more typically 1.4 to 3.0 times, for example 1.4 It can be up to 2.0 times.

The protrusions 19 extending in the vertical direction are provided between the eye holes 17 and 18 on the front and back surfaces of each element 12 and arranged so as to form a row with the ring 11. Since the protrusion 19 and the ring 11 are narrower than the element passage 50 in the slider 40 used in the second embodiment to be described later, and can be accommodated in the element passage 50, each element 12 moves through the element passage 50. Can serve as a guide when doing so.

The opening tool 13 is a component that enables connection and separation of the lower ends of a pair of chains, and includes a detachable first plate 13A and a second plate 13B. 1 and 2 show a state in which the plates are coupled, and FIG. 3 shows a perspective view showing a state in which the plates are separated from the back side. The first plate 13 A has eye holes 24 A for allowing the ring 11 to pass through, and is connected to one chain 10 A via the ring 11. The second plate 13 B also has an eye hole 24 B for passing the ring 11, and is connected to the other chain 10 B via the ring 11. A protrusion 21 is provided at the lower end of the first plate 13A.

A bottom plate 23 is provided at the lower end of the second plate 13B so as to reach the lower end of the first plate 13A, and the protrusion 21 is fitted into an opening 22 provided in the bottom plate 23. At the upper end of the second plate 13B, a head portion 28 that is engaged with the hook portion 15 of the adjacent element 12 is provided. When connecting the lower ends of one chain 10A and the other chain 10B, the projection 21 provided at the lower end of the first plate 13A is fitted into the opening 22 provided in the bottom plate 23 of the second plate 13B. Thereby, even if all the engagements between the elements of the pair of chains are released, it is possible to prevent the two chains from being completely separated. Further, when the lower ends of one chain 10A and the other chain 10B are separated, the protrusion 21 provided at the lower end of the first plate 13A fitted in the opening 22 provided in the bottom plate 23 of the second plate 13B. Is extracted from the opening 22. Thereby, both chains can be completely separated.

Referring to FIG. 2, the top stopper 14 is a part provided to prevent the

chains

10A and 10B from being further connected, and the hole of the ring 11 is partially or completely formed at the upper end of one chain 10A. It is attached so as to block. Thereby, since the hook part 15 of the element 12 facing the ring 11 cannot pass through the ring 11, the connection of the chains 10 A and 10 B is prevented. The shape of the top stopper 14 is not limited as long as it has the function. For example, the top stopper 14 may have a hole 26 and a baffle plate 27 for passing the ring 11.

Each element 12 can be provided with a mounting hole 20 and can be attached to various articles via a connecting member such as a ring or string. In particular, it can be suitably attached to the opening / closing part of the article. In this embodiment, as can be seen from FIG. 1 and FIG. 2, the mounting hole 20 is formed in the front and back direction at the outer edge of each element. In another embodiment, as shown in FIG. 4A, a hook-like element 12 ′ in which the mounting hole 20 can be opened and closed by a spring member 25 can be used. Here, the mounting hole 20 is provided at the outer edge of the element so as to open in the vertical direction, and the ring 29 can be mounted as shown in FIG. The opening 13 can also be provided with a mounting hole 20.

In this embodiment, the ring 11 without notches is used as the connecting member, but there is no particular limitation as long as the element can be connected by engaging the eye holes 17 and 18 of the element 12. For example, the connecting member can be a ring 53 provided with an inlet / outlet 51 as shown in FIG. It is preferable that an entrance / exit 51 of the ring 53 has an overlapping region 52 in contact with the ring member.

The material of the pair of chains 10 is not particularly limited, but metals such as zinc alloy, silver, and brass, plastics, and ceramics are conceivable.

The parts constituting the pair of chains 10 can be appropriately chamfered such as C chamfering or R chamfering. For example, the hook portion 15 is preferably chamfered to reduce catching on the ring 11 and the slider 40. It is preferable to chamfer the ring 11 and the eye holes 17 and 18 of the element 12 in order to smoothly rotate the element 12.

The connection and separation of the pair of chains 10 according to the present embodiment can be achieved, for example, by manually engaging and releasing the elements 12.
