Description

  The present invention relates to a fastener attachment that is detachably attached to both ends of a long accessory for jewelry and that connects both ends of the accessory in an annular shape.

  FIG. 3 shows a conventional necklace 31 as a long accessory for jewelry. Left and right chains 33R and 33L are connected to both ends of a charm portion 32, and the tip of each chain 33R and 33L The fastener 34 which connects parts detachably is attached.

  The fastener 34 has, for example, a crab 35 as an open / close hook attached to the tip of the chain 33R on the right side (left side as viewed in FIG. 3), and the left side (right side as viewed in FIG. 3) of the chain 33L. An adjuster chain 36 for adjusting the length is attached to the tip.

  When wearing this necklace 31 around the neck, hold the crab 35 with the right hand, hold the optional chain ring of the adjuster chain 36 with the left hand, turn both hands behind the neck, and turn the knob 35a of the cranican 35 with the fingertip of the right hand. The necklace 31 can be connected in an annular shape by sliding it to the chain ring of the adjuster chain 36 held with the left hand while opening the lock 35c of the hook 35b.

  However, the fastener 34 for this kind of accessory is made very small, and it is difficult to operate the knob 35a of the crab 35 in the invisible place behind the neck, and the fastener 34 is turned in front of the face. Even if it is attempted to operate while watching, the necklace 31 having a normal length is too short and the fastener 34 enters under the chin and cannot be visually recognized.

Further, even if the lock 35c of the crab can 35 can be opened behind the neck, it is difficult to hook the hook 35b on the chain ring because each chain ring of the adjuster chain 36 is small.
For this reason, recently, fasteners (clasps) using magnets have been proposed, and fastener attachments using these fasteners are also commercially available.

FIG. 4 is an explanatory view showing a conventional fastener attachment 41, and the same parts as those in FIG.
The fastener attachment 41 is composed of a pair of left and right connectors 42R and 42L that are used detachably attached to an existing necklace 31 having a fastener 34 attached to both ends, and the connectors 42R and 42L adsorb each other. The magnetic clasps 44R and 44L having the built-in strong magnets 43R and 43L are engaged and disengaged in the fitting direction.

  Further, a plate dharma 45 is connected to the magnetic clasp 44R of one connecting tool 42R, and a pulling ring 46, which is an openable hook, is connected to the magnetic clasp 44L of the other connecting portion 42L.

When the fastener attachment 41 is used, the plate dharma 45 of one connecting tool 42R is hooked on the crab 35 attached to the tip of the right chain 33R of the necklace 31, and the pull ring 46 of the other connecting tool 42L. Is attached to an arbitrary chain link of an adjuster chain 36 attached to the tip of the left chain 33L of the necklace 31.
At this time, it is necessary to open the lock 35c by sliding the knob 35a of the crab 35 or to open the lock 46c of the C-ring 46b by sliding the knob 46a of the pulling wheel 46. Can be mounted relatively easily.

  When wearing the necklace 31 to which the fastener attachment 41 is attached to the neck, hold the left and right chains 33R and 33L with the left and right hands and turn both hands behind the neck to bring them closer to the left and right clasps 44R. And 44L are magnetically attached by the magnetic force of the built-in strong magnets 43R and 43L, the necklace 31 can be easily connected in an annular shape.

However, the strong magnets 43R and 43L built in the magnetic clasps 44R and 44L have a strong magnetic force, so that they easily stick to those containing a ferromagnetic material such as an iron-based metal, which is inconvenient to handle. There are also aspects.
In addition, although strong magnets 43R and 43L are used, when a large tensile force acts in the longitudinal direction of the necklace 31 when a part of the coat is caught on the necklace 31 when the coat is taken off or attached, the clasp is removed. There was a risk that 44R and 44L would come off.

  Further, in the conventional fastener attachment 41, a plate dharma 45 to be hooked on the crab 35 of the necklace 31 is connected to one connecting tool 42R, and a pull ring 46 is provided on the other connecting tool 42L. The fastener 34 could not be used unless it was previously attached.

For example, an accessory chain with chain rings can be purchased in units of 10 cm at an accessory parts store, but the fasteners 34 are not attached to both ends as they are.
For this reason, one connecting tool 42L provided with the pulling wheel 46 can be attached to the chain ring at the end of the accessory chain, but the other connecting tool 42R provided with the plate dharma 45 cannot be attached.

  If the pull ring 46 of the connecting tool 42L is accidentally hooked to the crab 35 of the necklace 31 and the connecting tool 42L is first hooked to the right chain 33R, then the plate dharma 45 of the connecting tool 42R is moved to the adjuster chain. It is noticed that it cannot be hooked when trying to hook on 36, but in this case, there is a trouble that the previously attached connecting tool 42L must be once removed from the necklace 31 and attached again.

  Therefore, the present invention can be detachably attached to both ends of an existing necklace or accessory chain without fasteners, and can be easily connected in an annular shape without operating the open / close hooks behind the neck. It is a technical problem to provide a fastener attachment that can be easily removed even when a tensile force acts in the longitudinal direction of the long accessory.

In order to solve this problem, the present invention comprises a pair of connectors that are detachably attached to ring portions formed on both ends of a long accessory for jewelry, and that connect both ends of the accessory in an annular shape. A fastener attachment,
One connecting tool is connected to a male hook of a eyelet that has a spherical fitting protrusion formed on a base plate, and an open / close hook hooked to a ring portion on one end side of the long accessory is connected,
The other connector is a female hook of a eyelet that has a fitting hole that is detachably engaged by pushing the fitting protrusion in a direction orthogonal to the longitudinal direction of the long accessory. An open / close hook hooked to the ring portion on the other end side is connected.

  Since the fastener attachment of the present invention has an openable hook such as a pulling wheel connected to both of the pair of connecting devices, if ring parts such as a chain ring and a connecting ring are formed at both ends of the long accessory, Even if the fastener is not attached, the openable hook can be detachably attached to the ring portions at both ends of the long accessory.

  In addition, each connector is formed so that it can be connected with a male hook and a female hook of a eyelet cann, so hold the male and female hooks in both hands and turn your hand behind the neck, Are simply engaged with each other by simply pushing them into the fitting holes of the female hook, and the long accessory can be connected in an annular shape.

  At this time, the male hook is engaged with the female hook by being pushed in a direction orthogonal to the longitudinal direction of the long accessory, so that it is troublesome by being magnetically attached to another like a clasp using a magnet. In addition, even if a tensile force acts in the longitudinal direction of the long accessory, the male hook and the female hook are engaged in a direction orthogonal to the hook, so that it is difficult to come off.

In this example, it can be attached to both ends of an existing necklace, etc., and can be easily connected in an annular shape without operating the open / close hook in the invisible place such as the back of the neck. In order to achieve the object of making it difficult to come off even if force is applied, the following configuration is provided.
That is, it is a fastener attachment comprising a pair of connecting devices that are detachably attached to the ring portions formed on both ends of the long accessory for jewelry, and that connect both ends of the accessory in an annular shape,
One connecting tool is formed by connecting an open / close hook hooked to a ring portion on one end side of the long accessory to a male hook of a eyelet that forms a spherical fitting protrusion on a base plate,
The other connector is a female hook of a eyelet that has a fitting hole that is detachably engaged by pushing the fitting protrusion in a direction orthogonal to the longitudinal direction of the long accessory. An open / close hook hooked to the ring portion on the other end side is connected.

1 (a) and 1 (b) are perspective views showing a detached state and an engaged state of a fastener attachment according to the present invention, and FIGS. 2 (a) and 2 (b) are attached to a necklace which is a long accessory. It is explanatory drawing which shows the detachment | leave state and engagement state of the fastener attachment which concerns on this invention.
In addition, the same code | symbol is attached to the part which is common in FIG. 3, and detailed description is abbreviate | omitted.

  The fastener attachment 1 includes a pair of connectors 2M and 2F that are detachably attached to both ends of a necklace 31 as a long accessory for jewelry, and by engaging these connectors 2M and 2F with each other. Both ends of the necklace 31 can be connected in a ring shape.

One connecting tool 2M has a pulling ring 5M as an open / close hook connected to a male hook 4M of a eyelet can 3 via a circular ring 6M, and the pulling ring 5M is hung on a chain ring (ring part) of an adjuster chain 36 of a necklace 31. It can be stopped.
In the male hook 4M, a spherical fitting protrusion 8M is formed on one end side of the base plate 7M, and a connecting hole 9M for connecting the circular ring 6M is formed on the other end side.

The other connecting tool 2F is a crab (ring portion) in which a pulling ring 5F as an open / close hook is connected to a female hook 4F of the eyelet can 3 via a round ring 6F, and the pulling ring 5F is attached to the other end of the necklace 31. 35 so that it can be hung on 35.
In the center of the female hook 4F, a ring plate 7F is formed with a fitting hole 8F in which a fitting protrusion 8M of the male hook 4M is pushed in a direction Y perpendicular to the longitudinal direction X of the necklace 31 to be detachably engaged. The ring 9M which connects the round ring 6F is welded to the outer periphery.

The outer diameter of the spherical fitting protrusion 8M and the inner diameter of the fitting hole 8F of the eyemecan 3 are designed such that the maximum diameter portion passes through the fitting hole 8F when the fitting protrusion 8M is strongly pressed. Yes.
As a result, the male and female hooks 4M and 4F are engaged when the base plate 7M is pushed firmly with the fitting protrusion 8M aligned with the fitting hole 8F, and the head of the fitting protrusion 8M faces the base plate 7M in the engaged state. By pushing, it is removed from the fitting hole 8F and released from engagement.

  Each pulling wheel 5M and 5F is formed with a lock 13 that opens and closes by sliding the knob 12 at the opening of the C ring 11, and the ring 6M and 6F is connected to the outer peripheral surface of the C ring 11. 14 is welded.

The above is one configuration example of the present invention, and the operation thereof will be described next.
As shown in FIG. 2A, when the crab 35 is attached to the tip of the right chain 33R of the necklace 31 and the adjuster chain 36 is attached to the tip of the left chain 33L, one of the connectors 2M and 2F One is connected to the crab can 35 and the other is connected to the adjuster chain 36.
In this example, the connection tool 2F provided with the female hook 4F is connected to the crab can 35, and the connection tool 2M provided with the male hook 4M is connected to the adjuster chain 36.

When attaching the connecting tool 2F to the right chain 33R, the knob 35a of the crab 35 is slid to open the lock 35c, or the knob 12 of the pulling wheel 5F is slid to open the lock 13 and latch both.
Further, when attaching the connecting tool 2M to the left chain 33L, the knob 12 of the pulling wheel 5M is slid to open the lock 13 and hooked to an arbitrary chain ring of the adjuster chain 36.

When attaching the couplers 2M and 2F to the necklace 31, the necklace 31 is not attached to the neck and can be viewed in front of the eyes, so there is no difficulty even with relatively fine work.
In addition, since each of the couplers 2M and 2F of the fastener attachment 1 is provided with the pulling hooks 2M and 2F of the openable hooks, ring portions are formed at both ends even if the fastener 34 is not attached to the necklace 31. If it is, it can be installed without distinction between left and right.
Furthermore, by replacing and using one fastener attachment 1, it can be reused for other necklaces, and if it has a ring part, it can be attached to chains without fasteners. Very convenient.

  When the necklace 31 to which the connecting tools 2M and 2F are attached in this way is attached to the neck, the male hook 4M and the female hook 4F of the connecting tools 2M and 2F at both ends of the necklace 31 are gripped with the left and right fingers, Both necks 31 can be connected in an annular shape simply by turning both hands to the back of the neck and simply pressing the fitting protrusion 8M into the fitting hole 8F and pressing it firmly.

  At this time, since the male hook 4M is pushed in the direction Y orthogonal to the longitudinal direction X of the necklace 31 and engages with the female hook 4F, troublesomeness caused by being magnetically attached to another object such as a magnet clasp. In addition, even if a tensile force is applied in the longitudinal direction X of the necklace 31, the male hook 4M and the female hook 4F are engaged in the direction Y perpendicular to the male hook 4M, so that it is difficult to come off.

In the above description, the case where the pulling wheel 5M is used as the open / close hook has been described, but a crab can be used.
Moreover, although the case where it attached to the both ends of a necklace as a long accessory for accessories was demonstrated, it can also be used for a bracelet etc. besides this.

  The present invention can be applied to the use of a fastener attachment that is detachably attached to both ends of a long accessory for jewelry such as a necklace and connects the necklace in an annular shape.
