Description

  The present invention relates to a decorative fastener. More specifically, the present invention relates to a fastener that has a chain-like form or has a chain-like part, such as a necklace, a bracelet, an anklet, etc. The present invention also relates to a decorative article fastener that also has a function of adjusting the ring diameter of the chain portion.

  Conventional ornamental fasteners include a so-called pulling method using a spring and a so-called insertion method using a leaf spring.

For example, Japanese Patent Application Laid-Open No. 08-126506 discloses that the above-described Patent Document 1 includes a retaining ring having a through hole, a fixed disk having an insertion hole with a notch, and a rotating disk having an insertion hole having a notch. A fastener such as a necklace to which is attached is disclosed.

  However, this fastener does not have a function capable of adjusting the ring diameter of the chain portion. In addition, this fastener is a method of visually locking a pair of locking members, and since the locking members are usually very small, the pair of locking members are mutually correct. It is not easy to locate and lock at the locking position. Furthermore, in the case of a decorative article that locks the fastener behind the neck of the wearer, such as a necklace, the locking operation cannot be visually observed, so the above locking operation is particularly difficult, and the locking member is accurately engaged. It is difficult to confirm that it has been stopped.

The above-mentioned Patent Document 2 discloses a fastener such as a necklace made up of a male member having a protrusion with a bulging tip and a female member having a channel part into which the protrusion can be fitted. Yes. Then, one end of the channel part is opened to the outer periphery of the female member, and a spring wire is formed on the back side of the channel part so that the protrusion of the male member can be snap-engaged with the channel part, It is easy to lock.

However, this fastener also does not have a function of adjusting the ring diameter of the chain portion. or,
This fastener needs to locate the male member and the female member at the correct locking positions by groping, so it is difficult to operate and to confirm that the locking member is correctly locked. Essentially, there is no significant difference from the prior art described in Patent Document 1.

International publication WO2006 / 006476 gazette With respect to the above prior art, the inventor of the present application has proposed an excellent “decoration for chain-shaped end of an ornament” as described below in Patent Document 3 described above.

  That is, a fastener of a type for locking a holder provided at the end of one chain-like portion of the decorative article and a holder receiver provided at the end of the other chain-like portion, the holder and the holder receiver This is a decorative chain-like end fastener provided with one of magnets adsorbed to each other, or a magnet and a metal material adsorbed thereto as an adsorbing member at a site where these can be guided to the correct locking position. is there. In this fastener, more preferably, the holder is a spring-closed mouth clip that pivotally supports a pair of jaw members so that the pair of jaw members can be opened / closed, and the holder receiver is fitted between the pair of jaw members in the opened state. Thus, the locking member is locked.

  In this fastener, the holder and the holder receiver are simply positioned close to each other, and these are positioned at the correct locking position by the guide action of the suction member. Moreover, when the adsorbing members adsorb each other, a joining sound called “click” is generated, so that it can be confirmed by the joining sound that the holder and the holder receiver are located at the correct locking position. In other words, it is not necessary for the wearer to accurately place the holder and the holder receiver, which are small members, at the locking position to be locked. Therefore, for example, in the case of a decorative article that locks the fastener behind the neck of the wearer, such as a necklace, the fastener of the decorative article can be easily and easily locked.

  However, the fastener according to Patent Document 3 also does not have a function of adjusting the ring diameter when the chain portions of the ornament are connected in an annular shape.

  On the other hand, several members that aim only at adjusting the ring diameter of the chain portion have been proposed as exemplified in Patent Documents 4 to 7 below. In such a member, in general, the chain-like portion inserted into the member can be substantially fixed at all times, and the chain-like portion can be slid by pulling and sliding the chain-like portion as necessary. A function capable of adjusting the ring diameter is required.

In Japanese Patent Application Laid-Open No. 2006-136746, the elastic body incorporated in the casing as a fastener rotates in the casing, thereby allowing sliding movement of the chain for passing through the casing. Discloses a sliding structure of a chain for a body with an adjustment.

[Patent Document 1] Japanese Patent Laid-Open No. 2000-50920 Patent Document 5 discloses a chain-shaped accessory in which an elastomer is filled in an inner cavity of a drilled first accessory and an annular chain is passed through the inner cavity. By pulling the chain, it is possible to adjust the ring diameter of the chain by sliding the chain in the first accessory against the frictional resistance of the elastomer.

JP 2005-287999 A JP, 2000-287723, A Both above-mentioned patent documents 6 and patent documents 7 disclose the ring diameter adjustment tool of the chain using the elastic force by a spring. In short, a spring in a compressed state is provided inside the adjustment tool through which the chain is inserted, and the chain is elastically fixed between the spring and the inner peripheral portion of the wall of the adjustment tool. If the chain is pulled, the chain can be forcibly slid against the spring force of the spring and the ring diameter of the chain can be adjusted.

  As can be seen from the above-described state of the prior art, an excellent fastener according to Patent Document 3 is known as a fastener for an ornamental chain-shaped end, and separately, an adjustment member for the chain-shaped ring diameter is also provided. Several techniques are known.

  However, as a first technical problem, an excellent fastener for a chain-shaped decorative article that also has a function of adjusting the chain-shaped ring diameter has not been provided yet. If the fastener and the ring diameter adjusting member can be made into a single member, the appearance of the decorative article will be good. Furthermore, if the number of parts that are essentially necessary can be reasonably reduced by using a single member, it is a great advantage in the fabrication of a fastener that is a minute structure.

  As a second technical problem, all of the ring diameter adjusting members of the conventional chain are a system in which a friction resistance member or a spring member is substantially fixed in surface contact with the chain. It is not a fixed fixation using the concavo-convex structure of the chain which is a connected body. Therefore, even when the chain is unintentionally pulled with a weak force due to various operations of the wearer, there is a problem that the chain slides and the ring diameter is arbitrarily expanded.

  As a third technical problem, as a matter of course, in the above-described prior art, the fastening of the fastener and the adjustment of the ring diameter of the chain are performed separately. However, the ring diameter of the chain is usually adjusted according to the wearer's neck size, the preference of the wearing state, and the like when the decorative article is worn (when the fastener is locked). Therefore, it is extremely preferable if the latching mechanism of the fastener and the mechanism that permits the sliding movement of the chain (ring diameter adjustment) are interlocked.

  Then, this invention aims at solving said 1st-3rd technical subject in the ornament which consists of a chain | strand-shaped form or has a chain | strand-shaped form part.

(First invention)
The configuration of the first invention of the present application for solving the above-described problem is that a holder having a locking operation mechanism provided on one end side of the ornamental chain portion and a holder receiver provided on the other end side are provided.

  In the ornamental fastener according to the first aspect of the present invention, the ring diameter adjusting portion is configured to insert the chain-like portion and control the fixing and sliding movement inside the holder locking operation mechanism. The fastener and the ring diameter adjusting member are made into a single member, and the appearance of the decorative article is improved. Furthermore, since the ring diameter adjustment part is configured using the components of the locking operation mechanism essential for the fastener, no special parts for adjusting the ring diameter are required, and the number of parts of the fastener, which is a minute structure, is eliminated. Is reasonably reduced. From the above points, the first technical problem is solved by the decorative article fastener of the first invention.

(Second invention)
The structure of the second invention of the present application for solving the above problem is that the ring diameter adjusting portion according to the first invention is a component part of the locking operation mechanism of the holder and is inserted into the locking operation mechanism. It is a decorative article fastener constituted by a stopper part having a chain stopper of a size or shape that bites into the uneven structure of the chain-like part.

  According to the decorative article fastener of the second invention, a chain stopper is provided on a stopper part which is also a component part of the locking operation mechanism, and this chain stopper is provided with a concavo-convex structure of a chain-like part which is a connecting body of many small annular members To eat. Therefore, the chain-like part is firmly fixed by the chain stopper, so even if the chain is pulled unintentionally by various actions of the wearer, the chain slides and the ring diameter becomes arbitrary. There is no problem of expansion.

  Therefore, the first technical problem and the second technical problem are solved by the decorative article fastener of the second invention.

(Third invention)
The structure of the third invention of the present application for solving the above problem is that the stopper part according to the second invention is a thin spring material constituting a locking operation mechanism, and a part of it is eaten by the uneven structure of the chain portion. It is a decorative fastener that is a chain stopper.

  The ornament fastener of the third invention provides a preferred embodiment of the ornament fastener of the second invention.

  In the third invention, the fixing and sliding movement of the chain portion are controlled by the thin spring material. That is, since the chain portion is fixed by the spring material at all times and the spring material bites into the concavo-convex structure of the chain portion, the fixing is performed on the ring diameter adjuster according to Patent Document 6 or Patent Document 7 described above. Compared with certainty, there is no inconvenience that the chain-like portion slides without permission due to an unintended weak pulling force. Only when the chain portion is intentionally pulled with a relatively strong force, the chain portion slides.

(Fourth invention)
The structure of the fourth invention of the present application for solving the above problem is that the stopper part according to the second invention is a rigid part that operates to lock and unlock the holder, and a part of the stopper part has a pointed shape. The chain stopper bites into the uneven structure of the chain-like part when the holder is in the locked state, and the chain stopper retracts from the chain-like part when the holder is in the unlocked state. It is a fastener.

  The ornamental fastener of the fourth invention provides a preferred embodiment of the ornamental fastener of the second invention.

  In the fourth invention, the chain portion is fixed and the slide movement is fixed by the chain stopper of the rigid part biting into the uneven structure of the chain portion, and the chain stopper is retracted from the chain portion. Clearly switched by release. Moreover, the chain portion is fixed when the holder is in the locked state, and the chain portion is unfixed when the holder is in the unlocked state.

  Therefore, firstly, the control of the fixing of the chain-like part and the sliding movement is reliable, and secondly, the locking of the decorative article fastener and the control of the fixing of the chain-like part are interlocked. The first to third technical problems can be solved by the decorative article fastener of the fourth invention.

(Fifth invention)
The structure of the fifth invention of the present application for solving the above-described problem is that the holder according to any one of the first to fourth inventions is a spring-closed hook clip in which a pair of jaw members are pivotally supported so as to be able to open / close. The chain-like portion is inserted into one of the pair of jaw members, and the holder receiver is fitted and locked between the pair of open jaw members. It is a decorative article fastener which is a member.

  The specific structure of the holder and the holder receiver in the decorative article fastener according to the present invention is not limited as long as it falls under the provisions of the first invention, but preferably has a mouth clip type as defined in the fifth invention. be able to.

  In general, the mouth clip type holder as in the fifth invention is easy to operate the fastener. For example, in the case of an ornament that locks the fastener behind the wearer's neck, such as a necklace, the ornament fastener can be locked and unlocked due to the hook clip type. The operation can be performed more easily and reliably.

(Sixth invention)
The structure of the sixth invention of the present application for solving the above-described problems is that a support member pivotally supported between a pair of jaw members is provided in the mouth clip according to the fifth invention, and at the tip of the support member. A magnet or a magnet adsorbing metal material is provided as one adsorbing member, and a magnet or a magnet adsorbing metal material adsorbing to the one adsorbing member is provided as the other adsorbing member at the tip of the locking member. It is a decorative fastener.

  In the sixth aspect of the invention, the kind of the support shaft that performs the “shaft support” of the support member is not limited. For example, a shaft support by a support shaft that connects a pair of jaw members may be used. It may be a shaft support by the central part of the shaft.

  According to the decorative article fastener of the sixth invention, in addition to the effects described above with respect to the first to fourth inventions, an effect similar to that of the fastener according to Patent Document 3 can also be obtained.

  That is, only by roughly bringing the holder and the holder receiver close to each other, they are located at the correct locking position by the guide action of the suction member. Moreover, when the adsorbing members adsorb each other, a joining sound called “click” is generated, so that it can be confirmed by the joining sound that the holder and the holder receiver are located at the correct locking position. In other words, it is not necessary for the wearer to accurately position and lock the holder and the holder receiver, which are small members, at the locking position. Therefore, for example, in the case of a decorative article that locks the fastener behind the neck of the wearer, such as a necklace, the fastener of the decorative article can be easily and easily locked.

(Seventh invention)
The structure of the seventh invention of the present application for solving the above-mentioned problems is a decorative article fastener in which a part of the support member according to the sixth invention is formed in a pointed shape to serve as the chain stopper.

  According to the decorative article fastener of the seventh invention, an embodiment according to the fourth invention of the stopper part described above is provided.

  In other words, the support member according to the sixth aspect of the invention is a component part (support part for the suction member) of the locking operation mechanism in the shed clip type holder. The support member is positioned close to the jaw member when the holder is in the locked state, that is, when the pair of jaw members are closed, and is set when the holder is in the unlocked state, that is, one pair. When the jaw member is open, it is separated from the jaw member. Therefore, if a pointed chain stopper is formed on a predetermined portion of the support member (a portion close to the chain portion inserted into the jaw member), the chain stopper is locked when the holder is in the locked state. When the holder is in the unlocked state, the chain stopper can be retracted from the chain portion.

(Eighth invention)
In order to solve the above-mentioned problem, the present invention in the eighth invention is characterized in that the support member according to the sixth invention is connected to a pair of jaw members using a link arm which is a linear spring material for closing the lip clip. It is a decorative article fastener that constitutes a link mechanism in which the suction member protrudes from the opening when the pair of jaw members are opened, and has one or more of the following (1) and (2) .
(1) The link arm side end portion of the link arm that is connected to the jaw member is used as the chain stopper, and the chain arm is inserted into the concave-convex structure of the chain portion.
(2) A part of the support member is formed in a pointed shape to serve as the chain stopper, and is caused to bite into the uneven structure of the chain-like portion inserted into the jaw member.

  According to the decorative article fastener of the eighth invention, an embodiment of the above-described stopper part according to any one or more of the third invention or the fourth invention is provided.

  That is, the mouth clip of the eighth invention has a configuration in which a pair of jaw members are opened / closed in a spring-closing manner using a link arm which is a linear spring material, and a support member provided with a suction member is attached to the link arm. It is.

  Accordingly, in the above (1), the link mechanism is configured such that the suction member protrudes from the opening when the pair of jaw members are opened, and the link arm of the link mechanism can be used as a spring for closing the mouth clip. This is a rational configuration to be used, and the protruding suction member can be more easily attracted with the suction member on the locking member side, and the guide action of the suction member at the time of the locking operation is particularly effectively expressed. If a predetermined part of the link arm that is a linear spring material (a part close to the chain part inserted into the jaw member) is bitten into the uneven structure of the chain part, a chain is formed by a thin spring material. The fixing of the part and the sliding movement are controlled.

  Moreover, said (2) has the effect | action and effect similar to the case of 7th invention. When the chain stoppers (1) and (2) are set together, the fixing effect to the chain portion is extremely reliable.

  The decorative article fastener of the present invention has a good appearance by making the fastener and the ring diameter adjusting member into a single member, the number of necessary parts is reasonably reduced, and the ring diameter of the decorative article chain part is unpredictable. It does not expand due to the cause, and the locking mechanism of the fastener and the ring diameter adjustment mechanism work together.

  Next, the first to eighth embodiments of the present application will be described including the best embodiment.

[Attachment for decorative chain end]
The ornament fastener according to the present invention includes a holder provided on one end side of the ornament chain-like portion and having a locking operation mechanism, and a holder receiver provided on the other end side of the ornament chain-like portion. Consists of The holder and the holder receiver can be locked to each other by a locking operation mechanism on the holder side. The terms "holder" and "holder holder" are relative, and in essence, they refer to a pair of fasteners for chain-like ornaments, of which one has an operating mechanism for locking These members are simply called “holders”.

In the present invention, a ring that allows the end portion of the chain-like portion to pass through the inside of the holder's locking operation mechanism, fixes the chain-like portion using the components of the locking operation mechanism, and allows its sliding movement. The diameter adjustment part is comprised. A detailed description of the ring diameter adjusting portion will be described later. “Decoration” is not limited as long as it is a chain-shaped form or a decoration having a chain-shaped part. For example, a necklace, a bracelet, an anklet, etc. It can be illustrated preferably.

  Further, the “chain portion” means an elongated member that has at least a fine uneven structure and can be bent freely. As long as this condition is met, a string-like, belt-like or thread-like member made of a fiber material or the like, or a member in which a relatively small number of rod-like bodies are connected in a non-fixed manner is included. The constituent material of the member also includes, without limitation, various silica-based materials including jewelry, other inorganic materials, plant-based materials, plastics and the like in addition to metal. A typical example of the chain portion is a “chain” that is a connection body of a large number of small annular members.

[Holder and holder holder]
The type and structure of the holder and the holder receiver are not limited as long as the fastener is locked and unlocked by an arbitrary form and mechanism. The holder and the holder receiver are capable of positively locking the fastener at a predetermined correct locking position (or meshing state). Preferably, the holder and the holder receiver are each provided with one of suction members described later.

  As a particularly preferable holder and holder receiver, a holder is a spring-closed mouth clip in which a pair of jaw members are pivotally supported so that they can be opened / closed, and the holder receiver is fitted between the pair of opened jaw members. The case where it is the latching member latched is illustrated. In this case, a mechanism related to opening / closing and locking of the hook clip corresponds to a “holder locking operation mechanism”.

[Hook clip and locking member]
The spring-closed type hook clip and the locking member are those having at least the following configuration.

  That is, the above-mentioned spring-closed type mouth clip includes a non-intersecting type (basic form like a normal clothespin) in which a pair of jaw members are basically supported in parallel and a pair of jaws. Although the thing of the crossing type (for example, basic form like a Western scissors) with which a member is pivotally supported is considered, all of them are included by the mouth clip of this invention.

  The spring-closed type mouthpiece clip includes a pair of jaw members for sandwiching a locking portion of the locking member. The pair of jaw members are constrained to be pivotable by support shafts (usually the same support shaft), and the tip portions of the jaw members (clamping portions with respect to the locking members) are provided by spring means provided between the jaw members. Is biased to transition from an open state to a closed state.

  A state in which the distal ends of the pair of jaw members are closed, that is, a closed state of the mouth clip corresponds to a locking (meshing) state of the holder, and a state in which the distal ends of the pair of jaw members are open, That is, the opening state of the hook clip corresponds to a state where the holder is locked (engaged). In contrast to the mouth clip in the closed state, the above-described non-crossing type mouth clip opens the mouth clip by causing the rear end portions of the pair of jaw members to close against the biasing force of the spring means. In the above-described cross-type mouth clip, the mouth clip is opened by causing the rear end portions of the pair of jaw members to open against the biasing force of the spring means.

  In the example of the non-intersecting type mouthpiece clip, the spring-closed type mouthpiece clip can open the mouthpiece clip by picking the handle portion of the jaw member with a finger and rotating it in the closing direction. In this open state, after the hook clip is located at the meshing position with respect to the locking member, when the handle portion that has been picked with fingers is released, the hook clip is engaged with the locking member by the biasing force of the spring means, and the fastener Is locked.

  The locking member only needs to have an appropriate shape that can be fitted between the jaw members of the mouth clip in the open state, and an engagement portion that can be surely engaged with the jaw member of the mouth clip. In order to ensure the meshing reliability, a certain appropriate meshing shape can be formed at the tip of the jaw member. Since the locking member also needs to have an adsorption member corresponding to the suction member on the side of the lip clip as described later, there are various relations between the engagement shape portion of the engagement member and the setting of the adsorption member. There can be some design ingenuity.

[Adsorption member and support member]
The adsorbing member consists of a holder (for example, the above-mentioned hook clip) provided at the end of one chain-like portion of the decorative article and a holder receiver (for example, the above-described locking member) provided at the end of the other chain-like portion. Provided on both sides. These adsorbing members may be a combination of an N-pole magnet and an S-pole magnet that adsorb each other, or a combination of a magnet and a certain metal material (for example, iron material) adsorbed to this holder As the setting part of the suction member in the holder receiver, an appropriate part capable of guiding the holder and the holder receiver to the correct locking (meshing) position is selected. Since such a part changes variously according to the shape of the holder and the holder receiver, the meshing form, and the like, it is difficult to define it uniformly.

  When the fastener at the chain-like end of the decorative article is composed of the above-described hook clip and the locking member, one suction member may be provided inside the hook clip, and the other suction member may be provided at the tip of the locking member. Particularly preferred.

  In this case, the installation position of the suction member provided inside the shed clip is not limited. For example, the suction member can be installed in an inner portion of one or both of the pair of jaw members. In addition, an appropriate support member positioned between the pair of jaw members is set, and this support member is used as an adsorption member, or more preferably, an adsorption member is provided at the end of the support clip at the front end side of the mouth clip. it can. Such a support member can be held directly by the jaw member. In addition, when such a support member is provided, the support shaft that rotatably constrains the pair of jaw members is often passed through the support member. It is also possible to do.

  In the ornamental chain end fastener of the present invention, for example, a holder such as a hook clip is provided at the end of one of the chained parts of the ornament. More specifically, the ring diameter adjusting unit will be described later. Thus, the end of the chain-like portion is inserted into the inside of the jaw member (that is, inside the locking operation mechanism).

  In constructing the spring-closed mouth clip, the spring for closing the mouth clip can be directly attached to a pair of jaw members (without interposing other members). A spring that attaches directly to a pair of jaw members typically needs to be connected to the jaw members. Further, when the support member as described above is provided, this spring can be used as a fulcrum of the support member.

[Link mechanism]
As described above, in addition to a pair of jaw members, a support member that is an adsorbing member or a support member provided with an adsorbing member on the distal end side may be installed inside the mouthpiece clip. It may be supported by a spring for closing the mouth clip. In such a case, the spring for closing the shed clip can also act as a link arm on the pair of jaw members. In this case, a link mechanism is configured such that the suction member at the distal end of the support member protrudes from the opening when the mouth clip is opened.

  In such a link mechanism, the support member moves relative to the pair of jaw members in a specific direction (front end-rear end direction) when opening and closing the mouth clip. Therefore, when the support shaft (rotary shaft) of the jaw member passes through the support member, the support shaft needs to be configured to be slidable in the front-rear direction with respect to the support member. . For example, the slide member can be slid by providing a guide member with a guide groove having a width in the front-rear direction, passing the support shaft of the jaw member through the guide groove, and the support shaft into the guide groove. The structure which can be moved along can be illustrated.

[Ring diameter adjuster]
In the present invention, the ring diameter adjusting portion is configured by inserting the chain-like portion of the decorative article into the holder locking operation mechanism and using the components of the locking operation mechanism in the insertion portion. is there. The ring diameter adjusting part is for fixing the chain part at all times and allowing sliding movement of the chain part as needed to enable adjustment of the ring part ring diameter.

  The configuration of the ring diameter adjusting portion is not limited as long as it meets the above-mentioned conditions. Preferably, it is a component of the holder locking operation mechanism, and has a size or shape that bites into the concavo-convex structure of the chain portion. It is comprised by the stopper components provided with the stopper. Such a stopper component can be variously configured using any component of the holder locking operation mechanism.

  As a first preferred embodiment of the stopper part, when the holder locking operation mechanism uses a thin spring material as an indispensable part, the spring material is used as a stopper part, and a portion close to the chain portion in the spring material Can be used as a chain stopper to bite into the concavo-convex structure of the chain portion.

  In the first preferred embodiment described above, when the decorative article fastener is the spring-closed type mouth clip, the chain-like portion is inserted into one of the pair of jaw members of the mouth clip. A configuration in which a linear spring material for closing the mouth clip acts as the chain stopper on the chain portion is particularly preferable.

  Further, a support member supported by a support shaft that pivotally supports a pair of jaw members is provided inside the mouth clip, and this support member is paired using a link arm that is a linear spring material for closing the mouth clip. By connecting to the jaw members, a link mechanism is formed in which the suction member protrudes from the opening when the pair of jaw members are opened, and this link arm is used as a stopper part, A configuration in which the end portion on the side of the connecting portion acts as the chain stopper is particularly preferable.

  As a second preferred embodiment of the stopper part, when the holder locking operation mechanism includes a rigid part that performs a certain operation for locking and unlocking the holder, the rigid part is used as the stopper part. A form is mentioned. In this case, a portion close to the chain part in the rigid part is formed into a pointed end to form a chain stopper, and when the holder is in the locked state by using the operation of the rigid part, the chain stopper is uneven in the chain part. The chain portion can be fixed by biting into the structure, and when the holder is in the unlocked state, the chain stopper can be retracted from the chain portion to release the fixing of the chain portion.

  In the second preferred embodiment described above, when the decorative article fastener is the spring-closed type mouthpiece clip, the chain portion is inserted into one of the pair of jaw members of the mouthpiece clip. A configuration in which a support member, which is a rigid component supported between a pair of jaw members, is provided inside the mouth clip, and a part of the support member is formed in a pointed shape so as to act as the chain stopper is particularly preferable. preferable. In this case, the support member is positioned close to the jaw member when the mouth clip is in the closed state (the holder is engaged), and bites into the uneven structure of the chain portion to fix it. When the hook clip is in the open state (the holder is disengaged), the support member is separated from the jaw member, and the chain portion can be slid.

  The first preferred embodiment and the second preferred embodiment relating to the stopper component are realized together when the support member is supported by a link arm that is a linear spring material for closing the lip clip. It is also possible.

  Next, embodiments of the present invention will be described with reference to the drawings. The technical scope of the present invention is not limited by the following examples.

[Example 1]
(Configuration of Example 1)
The ornament fastener according to the present embodiment is a neck clip fastener of a lip clip type. The ornamental fastener 1 is composed of a hook clip 3 that is a holder and a locking member 4 that is a holder receiver provided at each end of the chain-like portion 2 of the ornament. The chain portion 2 is a chain that is a connected body of a number of small annular members, and has a structure with irregularities.

  In the shed clip 3, a pair of jaw members 6 are pivotally supported by the support shaft 5 in a non-intersecting manner. Since the pair of jaw members 6 have an outer shape close to that of a rectangular tube, they are supported by the same support shaft 5 to constitute a substantially rectangular tube-shaped mouthpiece clip 3 as a whole. . The pair of jaw members 6 can open / close the distal end portion (left end portion in the figure) of the mouth clip 3 by rotating about the support shaft 5. 1, 3, and 4 show the closed state of the shed clip 3, and FIG. 2 shows the opened state of the shed clip 3.

  A support member 7 is provided at the center of the substantially square tube-shaped mouth clip 3 constituted by a pair of jaw members 6. An N-pole magnet 9 is fixed to the tip of the support member 7. The N-pole magnet 9 is in a position retracted to the inner side (rear end side) from the front end portion in the closed state of the hook clip 3.

  The attachment structure of the support member 7 to the mouth clip 3 is as follows. That is, first, a guide groove 8 is provided in the support member 7, and the support shaft 5 is passed through the guide groove 8. Since the guide groove 8 has a certain width along the front end-rear end direction of the support member 7, the support shaft 5 can slide in the guide groove 8 along the front end-rear end direction. Next, in the support member 7, a central portion of the link arm 10 made of a thin linear spring material is inserted into a portion slightly rearward of the guide groove 8. This link arm 10 is a fulcrum of the support member 7. Both end portions of the link arm 10 are pivotally supported at the respective rear end portions (handle portions) of the pair of jaw members 6.

  Since the support member 7 is supported by the link arm 10 and the swinging of the support member 7 is restricted by the support shaft 5, when the opening / closing operation of the mouth clip 3 is performed, the relative relationship between the support member 7 and the mouth clip 3 is relatively small. The spatial relationship does not fluctuate or fluctuate irregularly except for a predetermined sliding movement along the front-rear direction.

  As can be seen from the opening state of the shed clip 3 shown in FIG. 2, the opening angle of both ends of the link arm 10 defines the protruding width of the support member 7 from the opening of the shed clip 3. Therefore, it is preferable to design the opening angle of the link arm 10 so that the protrusion width is relatively large.

  In the portion constituting the opening portion of the mouth clip 3, the upper jaw member 6 and the lower jaw member 6 are each formed with a stop portion 11 that slightly protrudes toward the inner peripheral side of the opening portion. On the other hand, the locking member 4 serving as a holder receiver includes a plate-like connecting member 12 having an opening in the center, and a square cylindrical S-pole magnet 13 connected to the tip of the connecting member 12. . As shown in FIG. 1, when the mouth clip 3 is closed and meshed with the locking member 4, the stopper 11 of the pair of jaw members 6 enters the central opening of the connecting member 12 and is closed. Therefore, the locking member 4 cannot be detached from the mouth clip 3.

  As for the N-pole magnet 9 and the S-pole magnet 13, the magnet on the support member 7 side may be an S-pole magnet, and the magnet on the locking member 4 side may be an N-pole magnet. Further, any one of these may be a metal material that is attracted to the magnet, and the other may be a magnet.

  Each end of the chain portion 2 is merely connected to the locking member 4 which is a holder receiver, but it can be seen particularly from FIG. 3 for the mouth clip 3 which is a holder. Further, it is inserted into the inside of the jaw member 6 on the lower side of the drawing, and is led out to the outside from a chain-like portion lead-out hole 14 provided in the jaw member 6. And the ring diameter adjustment part is formed in the jaw member 6 of the lower side of a figure at two places. A design in which any one ring diameter adjusting portion is not formed is also possible.

  The first portion is a chain stopper 15 formed by bending the linear spring material in the horizontal direction in the figure in the vicinity of the connecting portion of the link arm 10 with the jaw member 6 (see FIG. 4). The linear spring material that constitutes the chain stopper 15 is formed at a position that bites into the concavo-convex structure of the chain portion 2. When this spring material is configured at a position where it does not bite into the chain portion 2, the ring diameter adjusting portion is not formed.

The second part is a chain stopper 16 formed by protruding a part of the N-pole magnet 9 provided at the tip of the support member 7 in a pointed shape. As shown in FIG. 3, the chain stopper 16 bites into the concave-convex structure of the chain-like part 2 to fix the chain-like part 2 when the hook clip 3 as a holder is in the closed state (meshing state). As shown, when the shed clip 3 is in the open state (engagement release state), it retracts from the chain portion 2 and opens the chain portion 2. When the chain stopper 16 is not projected from the support member 7, the ring diameter adjusting portion is not formed.
(Operation of Example 1)
The ornament fastener 1 of Example 1 configured as described above is used as follows.

  That is, when the necklace is attached, the hook clip 3 is gripped by one hand and the locking member 4 is gripped by the other hand and turned toward the back of the neck, and the two are roughly positioned close to each other.

  At this time, when the handle portion (rear end portion) of the pair of jaw members 6 is rotated in the closing direction by using one hand holding the mouth clip 3, the mouth clip is resisted against the urging force of the link arm 10. 3 becomes the opening state shown in FIG. At the same time, as a result of the support member 7 being pushed out to the opening side of the shed clip 3 by the action of the link arm 10, the N-pole magnet 9 provided at the tip of the support member 7 protrudes from the opening of the shed clip 3. Accordingly, the N-pole magnet 9 at the tip of the support member 7 and the S-pole magnet 13 at the tip of the locking member 4 are attracted and coupled to each other.

  By this coupling operation, the mouth clip 3 and the locking member 4 are automatically guided and positioned at the correct meshing position shown in FIG. The fact that the hook clip 3 and the locking member 4 are located at the correct meshing position is that a “click” signal sound generated when the N-pole magnet 9 and the S-pole magnet 13 are attracted (collision sound between the magnets). Thus, it can be easily confirmed.

  After confirming the signal sound, the force of the hand that has rotated the handle portion of the mouthpiece clip 3 is loosened. Then, the hook clip 3 is returned to the closed state by the urging force of the link arm 10, and at this time, the distal end portion of the locking member 4 is pulled into the hook clip 3 together with the support member 7. As a result, the stoppers 11 of the pair of jaw members 6 are engaged with the S-pole magnet 13 of the locking member 4. Thereby, even if it does not visually observe, between the edge parts of the chain-shaped part of a necklace is simply and reliably latched.

  When removing the necklace, the hook clip 3 and the locking member 4 in the locked state are held by one hand, and the hook clip 3 is opened using the one hand holding the hook clip 3 in the same manner as described above. Then, the mouth clip 3 and the locking member 4 may be separated from each other against the attractive force between the N pole magnet 9 and the S pole magnet 13. In other words, unless the operation of opening the shed clip 3 against the urging force of the link arm 10 is performed, the locked state of the fastener 1 is not released.

  Next, with regard to the adjustment of the ring diameter of the necklace, when only the chain stopper 15 is configured, the neck clip 3 is in a meshed state or in a meshed release state. If the chain portion 2 is pulled with a strong force, the chain portion 2 slides and moves inside the jaw member 6 against the elastic pressing force of the chain stopper 15, so that the ring diameter of the necklace can be adjusted. .

  That is, in this case, the chain-like part 2 slides and moves by elastically deforming the linear chain stopper 15 that has been inserted in the concavo-convex structure of the chain-like part 2 across the horizontal direction in the figure. Since the chain stopper 15 bites into the concavo-convex structure of the chain-like part 2, the fixing force of the chain-like part 2 is higher than that of the ring diameter adjuster in which the friction resistance member or the spring member is brought into surface contact with the chain as in the prior art. When the chain portion 2 is slid and is slid, the chain stopper 15 is allowed to be elastically deformed. Moreover, the ring diameter adjuster described in Patent Document 5 has a problem in that the stopper function is lost due to wear of the filled elastomer over time, but the chain stopper 15 has a slight elasticity of the spring material. Since the mechanical deformation is utilized, there is no possibility that the stopper function is lost over time.

  As described above, a linear elastic member is fixedly provided in a positional relationship where the linear elastic member bites into the concavo-convex structure of the chain portion from the crossing direction, and this linear elastic member is used as a stopper member for adjusting the ring diameter of the necklace. In addition to the fastener of the present invention, the mechanism of (1) can be configured independently as a ring diameter adjuster of a necklace inside a small cylindrical container body inserted through the chain portion, or Even if it is configured as a ring diameter adjusting tool provided inside the holder or holder receiver of the fastener that does not have an operation mechanism, it is very effective.

  On the other hand, when only the chain stopper 16 is configured, or when the chain stoppers 15 and 16 are configured, the chain-shaped portion 2 is fixed by the chain stopper 16 when the mouth clip 3 is in the unlocked state. Therefore, if the chain portion 2 is pulled lightly or with a relatively strong force at that time, the chain portion 2 slides inside the jaw member 6 and the ring diameter can be adjusted.

[Example 2]
In Example 2, as shown in FIGS. 5 to 7, after the end of the chain-like portion 2 attached to the side of the mouth clip 3 as a holder is inserted into the lower jaw member 6, 5 and then inserted into the upper jaw member 6 and led out from the rear end side of the jaw member 6 to the outside. Then, in the vicinity of the connecting portion of the link arm 10 with the upper and lower jaw members 6 in the figure, the ring diameter adjusting portion is formed at two locations by the chain stopper 15 formed by bending the linear spring material in the horizontal direction in the figure. Is formed. A design in which any one ring diameter adjusting portion is not formed is also possible. In this embodiment, the chain stopper 16 is also shown, but it is practically useless.

  In the second embodiment, the configuration, operation, and effects other than those described above are the same as those in the first embodiment.

[Reference example]
In the reference example shown in FIG. 8, the configuration is basically the same as that of the first embodiment and the second embodiment, but the chain stopper 15 or the chain stopper 16 as a ring diameter adjusting portion for the chain portion 2 is configured. Instead, the ornamental fastener is located at a position where the chain portion 2 is inserted into the lower jaw member 6 and a position where the chain portion 2 is led out from the upper jaw member 6. A chain stopper 17 that is not a component of the one locking operation mechanism is fixed. The chain stopper 17 is a cylindrical body made of rubber or elastomer (for example, made of silicon rubber or soft silicone resin). The chain portion 2 is tightly inserted into the chain stopper 17, and the chain portion 2 is formed by friction resistance. Fixing and sliding movement are controlled.

  According to the present invention, the appearance is good by making the fastener and the ring diameter adjusting member into a single member, the number of necessary parts is rationally reduced, and the ring diameter is arbitrarily selected in the ring diameter adjusting mechanism of the decorative chain-like part. There is provided an ornamental fastener that does not have a problem of expanding and that further has a locking mechanism for the fastener and a ring diameter adjusting mechanism for the chain-like portion preferably interlocked.
