Abstract

PROBLEM TO BE SOLVED: To provide a novel connection structure by which connection/release operation of a connection element can be extremely simply performed, and to provide an accessory to which the connection structure is applied.SOLUTION: In the connection structure, there is a pair of connection elements comprising: an accepting/holding element 2 which has a holding frame body 21, holding space 22, pressing through release part 23, catch end part 24, and a pressing guide part 25; and a pressing engaging element 3 which has an engaging frame body 31 and an engaging acceptance part 32. As the characteristic of the structure, in an engaging acceptance state, while the engaging frame body 31 is applied to the pressing guide part 25, both are made to approach to each other, with the pressing through release part 23 opened by press-stretching the catch end part 24 in a part of the engaging frame body 31, receiving the engaging frame body 31 in the holding space 22, and storing the catch end part 24 inside (engaging acceptance part 32) of the engaging frame body 31. Also, in an engaging maintenance state, an engaging maintenance posture is maintained in which the engaging frame body 31 is away from the pressing through release part 23. Further, in an engagement detached state, in a manner that the pressing through release part 23 is expanded by the engaging frame body 31, both are relatively moved in a separating direction to release the connection state.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a connection structure suitable as a fastener for jewelry such as a necklace, a pendant, a bracelet, and an anklet. For example, the present invention relates to a novel connection structure that allows connection / release operations to be performed with a simple operation, and the application thereof Related to the new jewelry.

Conventionally, as a fastener 1 ′ that has been widely used for necklaces and pendants, for example, as shown in FIG. 9 (a), a pulling ring R 1 and a retaining ring R 2 (so-called dharma) are used as connecting elements, As shown in FIG. 9B, in many cases, a trigger-type hook-shaped pulling ring R1 ′ is used as a connecting element instead of the pulling ring R1.
However, such a conventional fastener 1 'has the following problems. First, since each connecting element itself is extremely small, the opening / closing operation end T is formed to be smaller, and therefore the opening / closing operation is extremely difficult to perform.

In the case of a necklace or the like, the opening / closing operation of the fastener 1 'is generally performed on the back side of the neck, and thus the wearer cannot visually check the opening / closing state of the pulling ring R1. Opening and closing operations were even more difficult. In particular, when the hand is pinching, such as in winter, the fingertip does not move as expected, and the opening / closing operation in such a case is difficult.
The opening / closing operation is usually performed by the wearer using both hands (for example, the pulling ring R1 is opened with the dominant hand (finger) and the retaining ring R2 is held with the other hand (finger)). Since it is difficult even for a healthy person as described above, it has become a more difficult operation for a person or an elderly person who cannot smoothly operate a hand or a finger.
Of course, if the size of the pulling ring R1 (R1 ') and the retaining ring R2 of the fastener 1' is increased, the opening / closing operation end T can be formed larger, so that the opening / closing operation of the fastener 1 'itself can be easily performed. If only the connecting element is formed larger than the main body 10 ', the design of the jewelry (jewelry) is unbalanced (the fastener 1' is a supporting role), and the fastener 1 'is generally formed of a bare metal. For this reason, it is not possible to increase the size of the accessory because it increases the overall cost of the accessory and increases the weight.

For this reason, there has been a demand for a fastener that can be opened and closed with a simple operation (see, for example, Patent Documents 1 to 3).
In the case of a bracelet that fits on the wrist, even a healthy person cannot use one hand (the hand that fits) for opening / closing operations (the opening / closing operation must be performed with one hand). The development of a detachable fastener was further demanded. By the way, when wearing such a bracelet, there were cases where, for example, temporarily attaching one end of the bracelet to the arm with cellophane tape etc., this was not the fundamental solution .

JP 2001-245714 A JP 2006-247090 A JP 2001-224212 A

  The present invention has been made in view of such a background, and has applied a novel connection structure in which connection elements can be easily connected / released (engagement receiving operation / engagement disengagement operation). The development of new accessories is a technical issue.

That is, the connection structure according to claim 1 is:
A pair of element members composed of an acceptance holding element and a push-in locking element is a connection structure configured to select an engagement maintenance state from an engagement acceptance state, and further an engagement disengagement state,
The receiving and holding element is formed in a holding frame, a holding space surrounded by the holding frame, a push-through opening part in which the holding frame is partially discontinuous, and a discontinuous end thereof. A catch end that elastically closes the push-through opening, and the catch end comprises a push-in guide at least outside the holding frame,
On the other hand, the push-in locking element is provided with a closed annular locking frame body, and the inside thereof serves as a locking receiving portion.
The receiving holding element and the push-in locking element are in the engagement receiving state, with the relative posture of both being set to an engagement receiving posture different from the locking maintenance posture, and the locking frame body of the push-in locking element is received and held And push the catch end with a part of the locking frame body in the push-in locking element to expand the push-out opening part, and a part of the locking frame body While pushing into the holding space, the catch end of the receiving holding element is housed in the locking receiving part of the pushing locking element,
Further, in the engagement maintaining state, the locking frame body of the push-in locking element maintains an engagement maintaining posture that does not face the push-out opening portion of the receiving holding element,
Further, in the disengaged state, with the locking frame body of the push-in locking element facing the push-out opening part of the receiving holding element, both are relatively moved in the separating direction so as to widen the push-out opening part. And the connection state is released.

The connection structure according to claim 2 is in addition to the requirement according to claim 1,
In the engagement maintaining posture, the catch end portion of the receiving and holding element is captured inside the locking frame body of the push-in locking element, and the opening of the push-through opening portion is prevented. is there.

Further, the connection structure according to claim 3 is in addition to the requirement according to claim 1 or 2,
The engagement / disengagement operation for disengagement is an operation of relatively pushing the push-in locking element relative to the reception holding element in substantially the same direction as when performing the engagement / acceptance operation for accepting the engagement,
The locking frame body of the push-in locking element is accommodated inside the holding space of the receiving holding element so that the connected state is released.

The accessory according to claim 4 is:
Attach the receiving holding element to one end of the jewelry body and attach the push-in locking element to the other end, and connect the holding frame of the receiving holding element and the locking frame of the push-in locking element at the time of wearing. Accessories to be engaged,
The connection structure according to any one of claims 1 to 3 is applied.

  First, according to the first or fourth aspect of the invention, the engagement receiving operation for connecting the receiving holding element and the push-in locking element and the engagement releasing operation for releasing the connection are performed with a simple and reliable operation. Can do. In addition, since the relative posture (engagement disengagement posture) of the two connection elements in the disengagement state is different from the engagement reception posture and the engagement maintenance posture, the engagement maintenance state can be firmly maintained. For example, when this connection structure is applied to a fastener of a jewelry, it is possible to prevent the jewelry from being accidentally detached in a normal use state. Further, since the engagement / disengagement operation is an operation of moving the catch end portion stored inside the locking frame body (locking receiving portion) to the outside of the locking frame body, the wearer can perform such engagement. The disengagement operation can also be performed with one hand (using the lever principle, for example), and even a person with a hand on one arm or finger can easily perform the disengagement operation.

  According to the second or fourth aspect of the invention, in the engagement maintaining state, the catch end portion of the receiving holding element is captured within the locking frame of the push-in locking element so that the push-through opening portion does not expand. Therefore, the engagement frame is not inadvertently passed through the open-through opening portion, and the engagement maintaining state can be firmly maintained.

  According to the invention described in claim 3 or 4, since the engagement receiving operation and the engagement disengaging operation are performed by pushing the pushing locking element into the receiving holding element in substantially the same direction (relative pushing). Attaching / removing jewelry can be easily performed, and erroneous operation due to misunderstanding of the wearer can be prevented. Moreover, since attachment / detachment of the accessory can be performed by pushing one connecting element in the same direction (since there is no need to perform different operations), the time required for attachment / detachment can also be shortened.

  The mode for carrying out the present invention includes one described in the following embodiments, and further includes various methods that can be improved within the technical idea.

Hereinafter, the present invention will be specifically described based on illustrated embodiments.
The connection structure of the present invention comprises the receiving holding element 2 and the push-in locking element 3 as a pair of connection elements, and is suitably used for the fastener 1 of the accessory N such as a necklace. For this reason, the receiving holding element 2 and the push-in locking element 3 are configured to be connectable / disengageable (linkable / separable) as shown in FIG. 1 as an example. In this specification, the term “engagement acceptance (operation / posture / state)” is mainly used to indicate an operation / posture / state in which both the receiving holding element 2 and the push-in locking element 3 are connected. The term “engagement / disengagement (operation / posture / state)” is mainly used to indicate the operation / posture / state for releasing the connection. Moreover, in the normal use state in which the wearer L wears the accessory N, the fastener 1 is naturally maintained in the engaged state (connected state) of both, and this engagement is not released. Therefore, for this state and the like, the term “engagement maintenance (state / posture / operation)” is mainly used.

Here, the basic structure of the accessory N such as a necklace will be described.
For example, as shown in FIG. 1 above, the accessory N is attached to the receiving and holding element 2 at one end of one accessory main body 10 (for example, a plurality of pearls or artificial pearls connected in series), and the other However, it is also possible to provide a plurality of accessories main bodies 10 in parallel with the pair of receiving and holding elements 2 and the push-in locking element 3 (multiple). is there.
Due to such a configuration, the receiving holding element 2 and the push-in locking element 3 are formed with portions (here, holes) for attaching the accessory main body 10 in a fixed state, which are respectively provided in the main body attachment holes 2h.・ Set to 3h. The vicinity of the body attachment holes 2h and 3h often serves as an operation end when performing an engagement receiving operation or an engagement disengaging operation. That is, for example, when the engagement receiving operation is performed such that the push-in locking element 3 is pushed into the receiving holding element 2, the wearer L sandwiches (pinch) the vicinity of the body attachment hole 3 h with a finger, and the operation is performed. This operation is often performed especially when the size of the connecting element is small.
Further, examples of the accessory N to which the connection structure of the present invention is applied include a bracelet and an anklet in addition to the necklace. By the way, pendants and chokers are included in the necklace in a broad sense. Of course, the connection structure of the present invention itself is not limited to the application to the accessory N, but can be applied to various connection portions, for example, belt hooks of bags, etc., and a load is lifted by a crane or the like. It can also be applied to the connection part (connection part) of the suspended load and the chain.

In the present invention, the engagement receiving operation for connecting the receiving holding element 2 and the push-in locking element 3 and the engaging / disengaging operation for releasing the connection can be performed by an extremely simple operation, and the engagement state is set. The main feature is that it can be maintained firmly.
Hereinafter, basic examples of the present invention and modified examples in which the configuration and the like are partially changed will be described.

[Example 1]
As shown in FIGS. 1B and 1C as an example, the connection structure (fastener 1) according to the first embodiment includes a holding frame body 21 having a substantially heart-shaped holding frame body 21 and a holding frame body 21 as shown in FIG. A holding space 22 surrounded by the frame body 21, a push-through opening portion 23 in which the holding frame body 21 is partially discontinuously formed, and a discontinuous end portion of the holding frame body 21, the push-out opening It comprises a catch end 24 that elastically closes (opens and closes) the part 23. Further, the catch end portion 24 is formed with a pushing guide portion 25 at least outside the holding frame body 21.
On the other hand, as shown in FIGS. 1B and 1C, for example, the push-in locking element 3 includes a closed annular locking frame 31 that is substantially oval (substantially oval) in plan view, The inside is referred to as a lock receiving portion 32. The latch receiving part 32 is a part for accommodating the catch end part 24 in the engagement maintaining state in which both (two connecting elements) are connected and this state is maintained. In FIG. However, it is also possible to form it as a non-penetrating recess, and it is only necessary that the catch end 24 can be accommodated inside the locking frame 31 in the engagement maintaining state. Even when the catch end 24 is housed inside the locking frame body 31 (the locking receiving portion 32), the receiving holding element 2 and the pushing locking element 3 can freely change their postures (relative postures). Preferably it can be changed.

In the engagement receiving operation for connecting the receiving holding element 2 and the push-in locking element 3, for example, the locking frame body 31 of the push-in locking element 3 is relatively moved from the outside of the push-out opening 23 of the receiving holding element 2. The catch end portion 24 is accommodated in the latch receiving portion 32 (in FIGS. 1 (b) and 1 (c), one frame body is in a connection state penetrating through the other frame). ing). For this reason, the state which connected two connection elements in a present Example exhibits the state which both connected like a chain | strand mutually.
Further, in the engagement / disengagement operation for releasing such a connected state, for example, as shown in FIG. 1B, the push-engagement element 3 is relatively pushed in substantially the same direction as the engagement receiving operation, The frame body 31 is pushed through the opening opening 23, and the locking frame body 31 is temporarily stored inside the receiving holding element 2 (holding space 22) (this operation releases the chain connection). , Both are to be separated.

  Here, in the engagement receiving operation and the engagement releasing operation as described above, the pushing operation of the pushing locking element 3 is described as “relative” because the pushing locking element 3 is pushed into the receiving holding element 2. In addition to this, the receiving holding element 2 may be pushed into the push-in locking element 3. Of course, it is also possible to push the two closer together, and the “relative” includes all such operations. In the following description, the term “relative” may be omitted when performing such an operation.

Further, the reason that the pushing direction when performing the engagement receiving operation and the engagement releasing operation is described as “substantially (the same direction)” is because the directions may not be exactly the same in a strict sense. That is, depending on the structure and shape of the receiving holding element 2 and the push-in locking element 3 or how the wearer L's hand (finger) moves, for example, it is fitted with a slightly upward push-in operation at the time of connection, but slightly downward at the time of connection release. In view of such pushing operation, it is described as “almost (pushing in the same direction)”.
In FIG. 1 (b), the engagement receiving operation and the engagement releasing operation are performed in a bending posture (lateral posture) in which the push-in locking element 3 is substantially orthogonal to the receiving holding element 2. However, the present invention is not necessarily limited to this. In other words, the push-holding element 3 may be connected to the receiving and holding element 2 in a vertical posture (circular connection posture) in which the push-holding element 3 is substantially straight (an aspect in which the push-locking element 3 is pushed from the long axis direction). This vertical posture is a posture in which the pushed-in locking element 3 (locking frame body 31) after connection is circumferentially aligned so as to fit the body of the wearer L (the shape of the wearing portion). In the present specification, it is mainly referred to as “circular connection posture”. In addition, if it is fitted in this circular connection posture from the stage of connection, it is naturally unnecessary to change the posture after connection.

The pushing guide portion 25 (in FIG. 1B and FIG. 1C, the outer peripheral side of the concave portion of the holding frame body 21 having a heart shape) is a portion that serves as a guide for the engagement receiving operation. That is, since the engagement receiving operation is an operation of pushing the locking frame body 31 relatively into the holding frame body 21 as described above, the locking frame body 31 is applied to the push-in guiding portion 25 to bring them closer together. If this is done, the catch end 24 can be gradually expanded naturally at the outer periphery of the locking frame 31, and finally the push-through opening 23 allows the locking frame 31 to pass. A part of the locking frame 31 enters the holding space 22 when it is opened.
As described above, in the first embodiment, the locking frame 31 of the push-in locking element 3 is brought into contact with the push-in guiding portion 25 (heart-shaped concave portion) of the receiving holding element 2 while the push-through opening 23 (catch end). 24), the push-in locking element 3 (locking frame body 31) naturally pushes the push-out opening 23 of the receiving and holding element 2 gradually. Eventually, the locking frame 31 passes through the push-through opening 23 and the catch end 24 fits in the locking receiving portion 32.

  As described above, in the engagement receiving operation as described above, for example, as shown in FIG. 1B, as an example, as shown in FIG. It is conceivable to push in with a relative posture). However, in that case, after the connection, the posture of the push-in locking element 3 is changed to the above-mentioned circular connection posture so as to fit the body of the wearer L (the shape of the wearing portion) (FIG. 1A). reference). In addition, for this reason, the receiving and holding element 2 and the push-in locking element 3 are each in an engaged state in which the catch end portion 24 is housed in the locking receiving portion 32 while maintaining this state. It is preferable that the posture can be changed freely.

Next, the engagement maintaining state will be described.
While the wearer L is wearing the accessory N, the two connecting elements are maintained in an engagement maintaining state in which the catch end 24 is housed inside the locking frame 31 (the locking receiving portion 32). . However, during normal use, a pulling force in the opposite direction acts on the receiving holding element 2 and the push-in locking element 3. For example, in the case of a necklace, the weight of the jewelry main body 10 acts on the two connecting elements in opposite directions, and in the case of a pendant, the load of the pendant top is further applied to the two connecting elements, and a pulling force in the separating direction acts on them. For this reason, in a normal use state, as shown by a solid line in FIG. 1C as an example, the two connecting elements have a locking frame 31 (oval frame) of the push-in locking element 3 in a heart shape. It is escaped to either the left or right of the push-through opening 23 located substantially at the center of the holding space 22 (this is the engagement maintaining state / posture).
Therefore, in a normal use state, the push-in locking element 3 (locking frame body 31) in the engaged state does not face the push-through opening 23 of the receiving and holding element 2. Here, the posture in which the push-in locking element 3 faces the push-through opening portion 23 is a posture indicated by an imaginary line in FIG. 1C, and this corresponds to an engagement / disengagement posture or an engagement reception posture.
Of course, if the wearer L jumps while wearing the accessory N such as a necklace, it is considered that the pulling force acting on the two connecting elements temporarily does not work. In some cases, the locking frame 31 may momentarily face the push-through opening 23. However, even in such a case, the holding space 22 of the receiving holding element 2 has a heart shape, and the push-through opening 23 is formed to protrude inside the holding space 22 having a heart shape. Therefore, the push-in locking element 3 does not pass through the push-out opening 23 from the posture facing the push-out opening 23 with the weight of the jewelry main body 10 or the load of the pendant top. (The engaged state will not be released).
As described above, the engagement maintaining posture (relative posture in the normal use state) of the two connecting elements is different from the engagement receiving posture and the engagement disengaging posture, and thereby the engagement maintaining posture is firmly maintained. The

Next, details of the engagement / disengagement operation will be described.
In the disengagement operation for releasing the engagement (connection) of the two connection elements, the locking frame body 31 of the push-in locking element 3 faces the push-out opening 23 of the receiving holding element 2 (engagement) In the disengaged state), both (the receiving holding element 2 and the push-in locking element 3) are relatively moved in the separating direction so as to expand the push-through opening 23, and the inside of the locking frame body 31 (the locking receiving part 32). ) Is moved to the outside of the frame of the locking frame 31 to separate them.
As described above, in this operation, as shown in FIG. 1B, the locking frame body 31 is pushed in substantially the same direction as in the engagement receiving operation, and the locking frame body 31 is pushed through. It is possible to disengage through engagement by disengaging through the opening 23 and placing it within the frame of the receiving and holding element 2 (relatively moving the catch end 24 out of the locking frame 31).

[Example 2]
As shown in FIG. 2 as an example, the connection structure (fastener 1) of the second embodiment is formed by a plate-like piece having a substantially elongated plate-like appearance as compared with the first embodiment. A rectangular hole serving as the receiving portion 32 is opened. In addition, the push-in locking element 3 is formed so that one end edge (one side) of the locking frame body 31 is long. For this reason, the locking receiving portion 32 is also close to the opposite tip of the body mounting hole 3h. Is formed.
On the other hand, the receiving and holding element 2 is formed so as to have a substantially heart shape in a plan view as in the first embodiment, but the holding frame body 21 itself is formed thicker than the first embodiment (so-called bone-like shape). Appearance).
In the second embodiment, when the engagement / disengagement operation is performed, the relative engagement / disengagement posture of the push-in locking element 3 is limited to some extent. Here, the push-in locking element 3 is set in a bending posture. The above engagement / disengagement operation is performed.
More specifically, for example, as shown in FIG. 2 (a), when the engagement receiving operation is performed, the push-in locking element 3 is pushed into the receiving holding element 2 in the circular connection posture, but when the engagement releasing operation is performed. For example, as shown in FIG. 2 (b), the push-in locking element 3 is changed into a bent posture and pushed in (released). The reason why the engagement receiving posture of the push-in locking element 3 is the circular connection posture is that this posture (state) becomes a posture (state) for wearing the accessory N as it is. Therefore, the engagement receiving posture of the push-in locking element 3 can be a bending posture.

In the second embodiment, the engagement / disengagement posture is limited to some extent because the longitudinal dimension 31L of the locking frame body 31 in the push-in locking element 3 is as shown in FIG. This is because the holding space 22 is longer than the longitudinal dimension 22L. That is, in such a case, even when the push-in locking element 3 is pushed into the holding space 22 in the circular connection posture at the time of disengagement, the push-in locking element 3 does not completely fit in the holding space 22 and the pushing operation in this direction is performed. This is because the engagement cannot be released.
Of course, only in the initial stage of the engagement / disengagement operation, the push-and-hold element 3 is pushed in the circular connection posture as shown in FIG. 2 (a), and the catch that has been held inside the lock frame 31 (lock receiving portion 32). If the end portion 24 is removed from the latch receiving portion 32 (if the catch end portion 24 is moved so as to sandwich the long frame portion), for example, the push-in locking element 3 is moved in the vertical direction from that state. It is possible to separate the two connecting elements by moving in a swaying direction (vertical direction in FIG. 2). However, such a multi-step engagement / disengagement operation is performed in the case of the accessory N such as a necklace, for example, because the wearer L must operate by turning his / her hand to the back side of the neck (operation in a situation where it cannot be visually observed). Operation that is difficult to perform and that can be easily removed by hand, that is, an operation that allows the push-in locking element 3 to be in a bent posture and can be removed by a single push-in operation (engagement as shown in FIG. 2B). A detachment operation is preferred.

In the connection structure (fastener 1) of Example 2 as well, the push-in locking element 3 maintains the engaged state with the receiving and holding element 2 as shown in FIGS. It is preferable that the posture can be freely changed (while the catch end portion 24 is accommodated in the lock receiving portion 32) (this is also a relative posture change). Of course, the engagement / disengagement posture of the push-in locking element 3 is not limited to the bending posture shown in FIG. 2B, and the push-in lock element 3 is pushed when the push-in lock element 3 is pushed in during the engagement / release operation. Any posture may be adopted as long as the locking frame body 31 can be accommodated in the holding space 22 of the receiving holding element 2, and various postures can be adopted.
In addition, as described above, the engagement receiving posture of the push-in locking element 3 can be a bending posture (similar to FIG. 1). In this case, the push-in locking element 3 is brought into the circular connection posture after connection. It is necessary to change and arrange the fastener 1 (the jewelry main body 10) so as to fit around the neck, for example (the same applies to FIG. 3 described later).

  Further, in the second embodiment, the push-out opening portion 23 of the receiving holding element 2 is formed so that the protruding tip to the holding space 22 is sharp (the tip of the mating surface between the push-out opening portions 23 becomes an acute angle. Formed). Thereby, even if the pressed-in locking element 3 in the engaged state comes into contact with the protruding tip of the push-through opening 23, the push-in locking element 3 is more likely to escape to the left and right of the push-through opening 23 ( The locking frame body 31 does not face the push-through opening part 23), and the engagement maintaining state is more firmly maintained. That is, in the second embodiment, the shape of the holding space 22 in a plan view is substantially a heart shape, the holding space 22 side of the push-through opening 23 is formed in a protruding state, and the protruding tip of the push-through opening 23 is The formation of an acute angle (inclined shape) or the like makes the engaged state (engaged maintained state) stronger.

Example 3
As shown in FIG. 3 as an example, the connection structure (fastener 1) of the third embodiment is configured so that the holding frame body 21 of the receiving holding element 2 is formed from an elongated plate (metal plate) having a substantially constant width in a side view. It is formed by being bent so as to form a generally “Ω (Greek letter capital omega)” shape, and the inner space of this “Ω” is defined as a holding space 22. Further, both end portions of the holding frame body 21 are curved and formed so as to expand outward toward the front end side, and this constitutes the push-in guiding portion 25.
Further, the both ends of the holding frame 21 are formed so as to be closest to each other, and this is the push-through opening portion 23. In addition, the push-through opening portion 23 is formed with a pair of reverse claws protruding inward of the push-through opening portion 23 so as to face each other by partially cutting out the central portion of the plate member forming the portion. This constitutes the catch end 24 as shown in the enlarged view of FIG. In the engagement maintained state, the reverse claw-shaped catch end 24 fits inside the locking frame 31 (the locking receiving portion 32). More specifically, the catch end 24 is locked and received. The part 32 is configured to be actively captured. In addition, the tip of the catch end 24 (the tip of the reverse claw) is formed so that the free end side is in close contact with each other in a normal use state (so-called nesting).
Incidentally, in order to form the receiving and holding element 2 of the third embodiment, for example, while punching the outer shape of the holding frame body 21 by pressing from a metal plate material having a certain thickness (while taking a blank), the catch end portion is also obtained. 24 can be punched and formed in a cantilever shape, and then the central portion and end portion of the metal plate can be curved to form the holding frame 21 and the push-through opening portion 23, which is suitable for extremely mass production (mass production). The shape (structure) can be said. As described above, the connection element, particularly the receiving and holding element 2 has the push-through opening portion 23, the catch end portion 24, the push-in guide portion 25, and the like, and thus tends to have a complicated shape (structure). Such a receiving and holding element 2 can be made into a shape (structure) suitable for mass production, thereby producing a special effect that the manufacturing cost of the fastener 1 can be suppressed.

On the other hand, the push-in locking element 3 is formed so that the locking frame 31 has a small rectangular plate-like outer shape, and a hole (here, a circular hole) serving as a locking receiving portion 32 is opened near the center thereof. Is done. Further, a pearl ball smaller than the pearl used in the jewelry main body 10 is provided on the distal end side of the locking frame body 31 (this is referred to as a locking maintenance lock 4). The lock 4 is configured to be accommodated in the holding space 22 (see FIG. 3B).
In addition, the engagement frame body 31 is attached to the opposite side of the engagement maintenance lock 4 so that a rectangular plate-shaped connecting body 33 is substantially orthogonal to the engagement frame body 31 (so-called staggered shape). A body attachment hole 3 h is formed in the connecting body 33. In addition, the said latching maintenance lock 4 is set to the magnitude | size which cannot be accommodated inside the holding | maintenance space 22 by expanding the push-through opening part 23 (passing through the catch end part 24).

Thus, in the third embodiment, the locking maintaining lock 4 that cannot pass through the push-through opening portion 23 (catch end portion 24) is provided on the distal end side of the push-in locking element 3 (locking frame body 31). Therefore, when the engagement receiving operation is performed, the two connection elements are brought close to each other while avoiding the lock maintaining lock 4 and the engagement is received.
Specifically, as shown in FIG. 3C, as an example, the receiving and holding element 2 is pushed into the push-in locking element 3 with the engagement receiving posture of the receiving holding element 2 as a bending posture with respect to the push-in locking element 3. Of course, in order to put such a fastener 1 into a normal use state, after receiving the engagement, the bending posture of the receiving and holding element 2 is changed to the circular connection posture (see the arrow indicated by the imaginary line in FIG. 3C). The fastener 1 (the accessory body 10) is adapted to fit around the neck of the wearer L.

  In addition, in the engagement maintaining state (the state where the catch end 24 is captured inside the locking frame 31 (the locking receiving portion 32)) in the third embodiment, an enlarged view of FIG. 3B is shown as an example. Thus, even if a pulling force in the separating direction acts on the two connecting elements, the reverse claw effect of the catch end portion 24 causes the inside of the lock frame body 31 (the lock receiving portion 32) and the catch end portion 24 to be reversed. Only by contacting the tip of the claw, it does not function to expand the push-through opening 23, and the engagement maintaining state is further strengthened.

Of course, if the pulling force in the separating direction applied to the two connecting elements is large, the catch end 24 will be disengaged from the inside of the locking frame body 31 (the locking receiving portion 32), that is, the push-out opening portion 23 will be forced. Although it is not at all impossible to spread, even if such a case occurs, since the locking maintenance lock 4 is housed in the holding space 22, this prevents the push-through opening 23 from spreading, The engagement maintaining state is more firmly maintained.
Thus, in the third embodiment, the engagement maintaining state is strengthened in multiple stages (multiple).
Incidentally, in FIG. 3 (c), it is shown that the receiving and holding element 2 is pushed into the push-in locking element 3 when performing the engagement receiving operation, and this is a relative pushing (with respect to the receiving and holding element 2). This corresponds to the relative pushing of the push-in locking element 3).

Next, the engagement / disengagement operation in the third embodiment will be described.
[Disengagement operation 1]
In order to perform the engagement / disengagement operation, as in FIGS. 1 and 2, after the locking frame body 31 is pushed through the opening portion 23 (after being bent), it is almost the same as that during the engagement receiving operation. It is possible to push the receiving and holding element 2 relative to the push-in locking element 3 in the same direction to separate them (see FIG. 3C). In this case, the push-in direction of the engagement receiving operation and the disengagement operation (the push-in direction of the connecting element) is almost the same push-in operation, which makes the operation easy and easy for the wearer L to misunderstand the operation. Is almost eliminated and the wearing time can be shortened.
Of course, the engagement / disengagement operation is performed so that the lock maintaining lock 4 does not pass through the catch end portion 24 (push-through opening portion 23), so that the receiving and holding element 2 is relatively moved from the circular connection posture to the bending posture. The engagement / disengagement operation is performed after changing to.

[Disengagement operation 2]
In addition, an engagement / disengagement operation other than the above is also possible. For example, as shown in FIG. 3D, the catch end 24 ( With the catch end 24) captured inside the locking frame 31 as the center of rotation, the two (the receiving holding element 2 and the push-in locking element 3) are rotated so as to approach each other to separate them. It is possible (the so-called lever principle).
In this case, due to the rotation, the side end face of the receiving and holding element 2 (holding frame body 21) comes into contact with the connecting body 33, and the turning force is blocked. A force that goes outward of the (locking receiving portion 32) acts, and the two connecting elements are separated (the disengagement operation is completed).

When the engagement / disengagement operation is performed based on the lever principle (when the engagement / disengagement operation is specified), the locking frame of the push-in locking element 3 is held in the holding space 22 at the time of engagement / disengagement. Since the body 31 does not need to be accommodated, the holding space 22 of the receiving and retaining element 2 does not need to have a size (an engagement / disengagement allowable dimension) for accommodating the locking frame body 31.
In addition, such an engagement / disengagement operation using the lever principle can be performed with only one hand (it is not always necessary to operate with both hands), and it is extremely easy to perform even for a person who has difficulty with one hand. Become. Of course, when the accessory N is a bracelet, even if it is a healthy person, the hand that fits the bracelet cannot be used for the operation. Therefore, the engagement / disengagement operation using the lever principle is extremely convenient for the healthy person. It can be said that it is an operation method.
Incidentally, the disengagement operation using the lever principle is an operation method that can also be applied in the first and second embodiments.

  As described above, in the engagement / disengagement operation, for example, when the locking frame body 31 is pushed in substantially the same direction as when the engagement is received, the holding frame body 31 is temporarily held in the holding space 22, so that the holding frame body 31 is held. The space 22 is required to have a size (an engagement / disengagement allowable dimension) in which the locking frame body 31 is accommodated. For example, in FIG. 2 described above, the size of the holding space 22 is set so that the locking frame element 31 that has passed through the engagement / disengagement push-in locking element 3, that is, the push-through opening 23, is accommodated inside the holding frame body 21. The shape and the like are set in advance. Specifically, when the engagement frame body 31 of FIG. 2 is engaged and disengaged in the circular connection posture, the longitudinal dimension 22L of the holding space 22 (the dimension capable of receiving the engagement frame body 31) is the engagement frame. It needs to be formed larger than the longitudinal dimension 31L of the body 31 (the dimension in the short axis direction when captured in an elliptical shape in FIG. 1B).

Example 4
As shown in FIG. 4 as an example, in the connection structure (fastener 1) of the fourth embodiment, the holding frame body 21 of the receiving holding element 2 is formed in a “U” shape in a side view. The inner space is the holding space 22, and the front end opening of the holding frame body 21 is the push-through opening 23. Further, the push-through opening portion 23 is formed in a circular shape in plan view, and its central portion is formed so as to protrude from both sides to the push-through opening portion 23 side (substantially cylindrical), and this constitutes the catch end portion 24. . Further, the opening side (holding frame body receiving side) of the catch end portion 24 is formed in an inclined shape so as to guide the receiving of the locking frame body 31, and this constitutes the pushing guide portion 25.

On the other hand, the push-in locking element 3 is formed by attaching a ring-shaped locking frame 31 to one end of a small block having an elongated rectangular parallelepiped outer shape, and a circular hole serving as a locking receiving portion 32 is opened inside thereof. The Further, a locking maintenance lock 4 for reinforcing the engagement maintaining state is formed at the engagement tip of the locking frame body 31 so as to protrude upward and downward (up and down in FIG. 4). The locking maintenance lock 4 is configured to be hooked on the catch end 24 (non-inclined surface side).
In FIG. 4, the main body attachment holes 2h and 3h provided in the two connection elements are omitted. In addition, a small block having an elongated rectangular parallelepiped outer shape in the push-in locking element 3 is partially formed in a hollow shape, and design unification with the receiving and holding element 2 is achieved (also for weight reduction). contribution).

As described above, also in the fourth embodiment, the engagement maintaining lock 4 is formed at the engagement tip portion of the engagement frame body 31. Therefore, in the engagement receiving operation, the two connection elements are connected while avoiding this portion. It is made to approach each other and to accept engagement.
Specifically, as shown in FIG. 4B as an example, the receiving and holding element 2 is pushed into the push-in locking element 3 in a bent posture, for example. Of course, the receiving and holding element 2 after receiving the engagement is changed from the bent posture to the circularly connected posture (see the arrow indicated by an imaginary line in FIG. 4B), and the fastener 1 (the main body 10) is, for example, a neck or the like. It will be arranged to fit around.

In the fourth embodiment as well, the engagement / disengagement operation of the two connecting elements is performed by pushing the receiving holding element 2 in the same direction as when receiving the engagement, as in FIGS. It can be taken (see FIG. 4B).
For example, as shown in FIG. 4 (c), the push-in locking element 3 and the receiving and holding are held around the catch end 24 in the engaged state (contained inside the locking frame 31) as the center of rotation. It is also possible to turn the element 2 close to each other (so-called lever principle) to disengage the engagement.

Incidentally, this kind of fastener 1 (connection structure) is often arranged at a portion that is not conspicuous at the time of wearing. For example, in the case of a necklace, the fastener 1 is usually on the back side of the neck which is difficult to see with hair. It is common to place it on This is probably because the conventional fastener is composed of, for example, a pulling ring R1 and a retaining ring R2 (a plate with a hole called a dharma) and lacks designability compared to the jewelry main body 10. However, with the fastener 1 (connection structure) according to the present invention, the receiving holding element 2 and the push-in locking element 3 itself can have excellent design (decorativeness), and therefore the engagement is maintained. It is possible to place the two connection elements in the state on the main body of the jewelry N such as a pendant top. In this case, the engagement receiving operation and the disengaging operation performed on the back side of the neck can be performed in front of the wearer L (for example, the chest), and the wearer L can directly observe the operation process. Alternatively, it can be performed while confirming by reflecting in a mirror, and the connection / release operation is further facilitated.
Of course, improving the design of the fastener 1 and placing it on the main body of the accessory N is a concept common to the respective embodiments (modified examples), and is not limited to any of the embodiments. In each of the above-described embodiments, each connecting element is formed symmetrically (symmetry), and therefore, it is easy to produce a design beauty (harmonious beauty) indispensable for the accessory N. By the way, with the conventional connection element (drawing ring and retaining ring), for example, the pulling ring is mounted with the pendant top facing the front of the wearer L so that the opening and closing operation of the pulling ring performed by the wearer L can be easily performed. However, in the above embodiment, such consideration is not necessary.

[Other Examples]
The present invention has the above-described embodiment as one basic technical idea, but the following modifications can be considered.
First, in the basic embodiment described above, the holding frame 21 of the receiving holding element 2 has an appropriate depth dimension, but is basically a frame having a substantially constant cross-sectional shape (a flat frame). It was formed.
However, the holding frame body 21 of the receiving holding element 2 can be formed as a three-dimensional frame body (so-called three-dimensional frame), for example, as shown in FIG. That is, the modified example shown in FIG. 5 includes, as an example, a holding frame 21 that is formed by joining three substantially C-shaped frame members in a circular shape of 120 degrees each and surrounded by three frame members. The inner space is the holding space 22. In FIG. 5, the C-shaped frame member is joined only at one end (here, the lower side) where the main body mounting hole 2h is formed, and each frame member is joined at the other end (here, the upper side). A gap is formed, and this gap becomes the push-through opening 23.
The upper end of each frame member is formed in an acute angle downward (so-called “return”), and this is referred to as a catch end 24. Further, the opposite side of the catch end 24, that is, the upper edge where the three frame members are concentrated is formed in a chamfered shape, and the chamfered structure and the gap between the frame members function as the push-in guiding portion 25.

  On the other hand, the push-in locking element 3 is formed so that the locking frame 31 has a rectangular plate-like outer shape, and a hole (here, a circular hole) as a locking receiving portion 32 is opened near the engagement tip. Is done. Further, an engagement maintaining lock 4 is provided at the engagement tip of the engagement frame body 31.

Next, the engagement receiving operation in this modified example will be described.
In the engagement receiving operation for connecting the two connecting elements, for example, as shown in FIG. 5 above, the push-in locking element 3 (locking frame body 31) is moved into the frame in the receiving holding element 2 (holding frame body 21). The member is inserted from a gap where there is no member. At this time, the push-in locking element 3 (locking frame body 31) is fitted using the push-in guiding portion 25 formed on the upper edge of the frame member as a guide.
Next, in order to bring both members into the engagement maintaining state (to perform the engagement maintaining operation), the catch end portions 24 of the three frame members are provided inside the locking frame body 31 (the locking receiving portion 32). The push-in locking element 3 (locking frame body 31) is operated so as to be accommodated at the same time. Of course, in this state, the engagement maintaining lock 4 is accommodated inside the holding space 22, and the engagement maintaining state is firmly maintained.

In the first to fourth embodiments described above, the receiving and holding element 2 (holding frame 21) is mainly formed of a single member, and a catch end portion is formed by forming a push-through opening portion 23 at one end of the member. 24 was closed (opened / closed) elastically.
However, the receiving and holding element 2 is not necessarily formed by one member (it is not necessary to open and close elastically by forming an opening at one end of one frame member), for example, as shown in FIG. It is also possible to adopt a configuration in which two clamping members 26 are opposed to each other, and the clamping action portion (catch end portion 24) is biased in the closing direction by a spring (torsion coil spring) 27, which has a pinch (so-called laundry pinch) structure. It is the same.
In the receiving and holding element 2, an operation end 26 t as shown by an imaginary line in FIG. 6 can be formed on the rear end side (opposite the catch end portion 24) of the clamping member 26. Accordingly, for example, in an emergency, by operating both the operation ends 26t, the push-through opening portion 23 (catch end portion 24) is instantaneously opened, and the push-in locking element 3 is immediately detached from the receiving and holding element 2. It can be made to.

  In the first to fourth embodiments described above, the holding frame 21 of the receiving holding element 2, particularly the catch end 24 and the push-through opening 23 are formed symmetrically, and both ends of the holding frame 21 are elastic. However, the holding frame body 21 is not necessarily limited to such a structure. That is, as shown in the side view (lower side) of FIG. 6 as an example, the holding frame body 21 may have both ends of the holding frame body 21 formed asymmetrically. In many cases, the structure is mainly bent (when viewed microscopically, the other end is also bent, but can be ignored in practice).

In the first to fourth embodiments described above, the locking frame 31 of the push-in locking element 3 is formed so that the outer side of the locking receiving portion 32 is continuous in a circumferential shape (so-called so-called). Closed ring). However, the locking frame body 31 is not necessarily limited to such a structure. For example, as shown in FIG. 7, a part of the locking frame body 31 may be formed discontinuously. In this case, in the engagement receiving operation, the locking frame 31 can also be elastically expanded by the discontinuous portion, so that the engagement receiving operation becomes easier, but on the other hand, the presence of the discontinuous portion There is a concern that the disengagement may be performed carelessly. For this reason, it is preferable that the gap between the discontinuous portions is set to a very narrow interval or zero so that such inadvertent disengagement is not performed. Or about the latching frame 31, adjusting the rigidity of a member etc. so that elastic opening and closing is not substantially performed by this discontinuous part etc. is assumed. In view of such considerations, the “closed annular locking frame” described in the claims includes the locking frame 31 in which the discontinuous portion is formed.
Further, in this case, the push-in locking element 3 is discontinuous at a part of the locking frame body 31 and has an appearance similar to that of the receiving and holding element 2. It is also possible to configure the jewelry main body 10 by connecting a large number.

Further, the modified example shown in FIG. 8 is a modified example in which the opening of the push-through opening portion 23 (catch end portion 24) in the engagement maintaining state is more surely prevented. As an example, as shown in FIG. 8, the tool 1) has a holding frame body 21 of the receiving holding element 2 formed in a substantially “Ω” shape in plan view, and this inner space of “Ω” is defined as a holding space 22. (Similar to Example 3). Further, both ends of the holding frame body 21 are curved outwardly toward the distal end side, and this constitutes the push-in guiding portion 25.
Further, the both ends of the holding frame 21 are formed in a face-to-face shape with a gap, and this gap forms a push-through opening portion 23, and the face-matching portion serves as a catch end portion 24. In addition, the holding space 22 side of the catch end 24 is formed in a protruding state, and the tip facing the push-through opening 23 is formed in an acute angle state as shown in the figure, and this acts as the lock maintaining lock 4. That is, in the engagement maintaining state, this acute angle portion is fitted into the frame portion 41 formed at the tip of the push-in locking element 3, and the push-through opening portion 23 (catch end portion 24) is maintained so as not to expand. (The engagement maintaining state is kept even stronger).

  On the other hand, the push-in locking element 3 is formed as a long and narrow plate-like piece with one end edge (one side) of the locking frame 31 being long, and is engaged with the distal end side facing the body attachment hole 3h. A hole as the stop receiving portion 32 is opened (similar to the second embodiment). In addition, the push-in locking element 3 is provided with a frame portion 41 that functions as the locking maintaining lock 4 at the tip of the locking receiving portion 32. By engaging (hanging) with the tip of the end portion 24, the engagement maintaining state is kept even stronger.

For example, as shown in FIG. 8A, the engagement receiving operation for connecting the receiving and holding element 2 and the push-in locking element 3 is performed by setting the push-in locking element 3 in a bending posture. It is pushed into the opening 23). Specifically, as shown in FIG. 8A, the locking frame body 31 of the pressing locking element 3 is gradually pushed into the inner side of the push-out opening 23 while being applied to the pressing guide 25. With this push-in, the locking frame 31 pushes the catch end 24 of the receiving and holding element 2 to the left and right to open the push-out opening 23.
Further, as the locking frame 31 pushes the catch end portion 24 to the left and right, as shown in FIG. 8B, the posture of the push-in locking element 3 (the locking frame 31) is gradually increased. When the push-in locking element 3 takes the circular connection posture, the catch end 24 is completely accommodated in the lock receiving portion 32 of this (the catch that has been expanded). The end 24 is elastically closed).

Thereafter, as shown in FIG. 8 (c), the push-in locking element 3 is moved (pulled) toward the main body attachment hole 3 h, and the frame portion 41 of the push-in locking element 3 is moved to the catch end of the receiving holding element 2. The outer fitting portion 24 is fitted on the portion 24, whereby the expansion of the push-through opening portion 23 is more firmly prevented and the engagement maintaining state is further strengthened (solid locking state).
In addition, in connection structure (fastener 1) of FIG. 8, in order to perform engagement / disengagement operation, it can perform by performing the operation mentioned above reversely.
