Description

  The present invention relates to a fastener for jewelry used for a necklace or a bracelet.

2. Description of the Related Art Conventionally, the following accessories are known as accessories for connecting accessories such as necklaces and bracelets.
4 and 5 includes a female member 1 connected to one end of a necklace and a rod-shaped male member 2 connected to the other end.
The female member 1 is composed of a main body 3 and a lid body 4, and the main body 3 stands up around its bottom plate portion 5 to form an upright portion 6, and the lid body 4 hangs down around the ceiling plate portion 7. The hanging part 8 is used.

Shaft holes 9 and 10 are formed in each of the standing part 6 of the main body 3 and the hanging part 8 of the lid body 4 as described above. These shaft holes 9 and 10 are made to coincide with each other when the main body 3 and the lid body 4 are combined so as to overlap each other.
Then, the rotation support shafts 11 and 12 are passed through the matching shaft holes 9 and 10, and the female member 1 and the male member 2 are rotatably supported around the rotation support shafts 11 and 12.

  The rotation support shafts 11 and 12 as described above are composed of one elastic bar member B. The one elastic rod member B has both ends serving as rotation support shafts 11 and 12, and coil rotation portions 13 and 14 that exert a spring force in the torsional direction are continuously connected to the rotation support shafts 11 and 12. Yes. Further, the coil spring portions 13 and 14 are continuous via a concave bottom plate pressure contact portion 15 that contacts the bottom plate portion 5.

Further, both ends of the bottom plate pressure contact portion 15 are continuous with the rotation support shafts 11 and 12 through looped ceiling plate pressure contact portions 16 and 17.
Further, the upright portion 6 of the main body 3 and the hanging portion 8 of the lid body 4 are combined to constitute an opening 18 into which the male member 2 is inserted.

  Then, when the rotation support shafts 11 and 12 are passed through the shaft holes 9 and 10 and the main body 3 and the lid body 4 are rotatably combined, the bottom plate press contact portion 15 and the ceiling plate press contact portions 16 and 17 are formed. The coil spring portions 13 and 14 are pressed against the bottom plate portion 5 or the ceiling plate portion 7 while being bent. As described above, when the bottom plate pressure contact portion 15 and the ceiling plate pressure contact portions 16 and 17 are pressed against the bottom plate portion 5 or the ceiling plate portion 7 while bending the coil spring portions 13 and 14, the opening 18 portion is closed. Force is acting.

  Therefore, when the male member 2 is pushed in from the opening 18, the main body 3 and the lid body 4 rotate in a direction to open the opening 18 against the elastic force of the coil spring parts 13 and 14. And if the male member 2 is pushed in until the annular recessed part 19 formed in the male member 2 corresponds to the opening part 18, the main body 3 and the lid body 4 will rotate in the direction which closes the said opening part 18 part, and an opening part will be carried out. The peripheral edge of 18 is hooked on the annular recess 19. If the peripheral edge of the opening 18 is caught in the annular recess 19 in this way, the male member 2 cannot be removed from the female member 1 and both ends of a jewelry such as a necklace are connected.

Moreover, if the main body 3 and the lid body 4 are rotated against the elastic force of the coil spring portions 13 and 14 in the above state, the opening 18 opens, so that the male member 2 can be pulled out from the female member 1. it can.
On the bottom plate portion 5 of the main body 3 as described above, a support portion 20 that supports the male member 2 inserted into the female member 1 is formed, and a support recess portion 21 is formed in the support portion 20. .

The cover body 4 is also provided with a support recess corresponding to the support recess 21 formed in the support portion 20, but the support recess of the cover body 4 is not shown.
Further, when the main body 3 and the lid body 4 are combined as described above, the support concave portion of the lid body 4 and the support concave portion 21 of the main body 3 coincide with each other to form an insertion hole into which the male member 2 is inserted. I try to do it. The opening 18 is positioned in the extending direction of a straight line passing through the center of the insertion hole, and the straight line is orthogonal to the rotation center of the main body 3 and the lid body 4.

Each of the main body 3 and the lid body 4 of the female member 1 as described above is integrally molded by casting. The reason for the integral molding is as follows.
That is, each of the main body 3 and the lid body 4 is provided with a support recess, but the opening 18 must face the extending direction of a straight line passing through the center of the insertion hole formed by the support recess. I must.

  If the insertion hole and the opening 18 do not oppose each other in the linear extension direction, when the male member 2 is inserted into the female member 1 from the opening 18, the male member 2 and the insertion hole are relatively The position will shift. If the relative positions of the two are shifted, when the male member 2 is inserted from the opening 18, the tip of the male member 2 hits the support portion 20, and the male member 2 cannot be pushed into the annular recess 19. . Therefore, the male member 2 easily comes off from the female member 1.

  On the other hand, if there is no said insertion hole, the male member 2 will not be stabilized in the female member 1, and will oscillate at the part of the opening part 18. FIG. If the male member 2 swings around the opening 18, the male member 2 may pry open the opening 18 in some cases. If the opening 18 is pry open, the male member 2 is easily detached from the female member 1.

In any case, in order to solve the above problems, the relative position between the insertion hole and the opening 18 must be accurately determined.
Therefore, as described above, the main body 3 and the lid body 4 are integrally formed by casting so that the relative position between the insertion hole and the opening 18 is accurately determined.

JP 2011-010740 A JP 2008-307305 A

The conventional fasteners for jewelry are integrally formed by casting in order to accurately determine the dimensional relationship between the main body and the lid body as described above. Certainly, the integral molding by casting can accurately determine the dimensional relationship, but it is inevitable that the thickness of the main body and the lid body is increased.
If the wall thickness is increased, the amount of bullion increases as a matter of course, and the weight of the entire stopper increases accordingly.

If the weight of the stopper becomes heavier than necessary, for example, when the necklace is wrapped around the neck, the heavy stopper moves downward around the neck and becomes completely visible, which makes it look bad. A problem occurs.
In addition, when an expensive precious metal is used, there is a problem that the material cost increases as the amount of bullion increases.

  In addition, it is also conceivable that the support portion is formed of a member different from the main body and the lid body, and they are bonded to the main body and the lid body by welding or the like. However, since the main body and the lid body are very small, welding itself to the small main body and the lid body itself is a rather difficult operation. Therefore, bonding the support part to the main body or the lid body by welding or the like has a problem that productivity deteriorates.

  An object of the present invention is to provide a fastener for jewelry that can accurately set the dimensional relationship of an insertion hole into which a male member is inserted while reducing the weight, and is also useful for improving productivity.

The present invention includes a male member connected to one end of an accessory such as a necklace and a female member connected to the other end of the accessory. The female member is composed of a main body and a lid body, and the main body and the lid body are combined to form an opening into which the male member is inserted. An elastic force that rotates in the direction of reducing the opening diameter is applied.
Then, it is assumed that the fastener for jewelry is configured such that when the male member is pushed into the opening against the elastic force, the male member is hooked at the edge of the opening.

In the first invention, the main body is formed of a press-molded body in which an upright portion rises from the periphery of the bottom plate portion. And while the said lid body contacts this standing part, the said female member is comprised, On the inner side surrounded by the said standing part, it is comprised with a member different from the said main body, and the said male member is inserted A support member in which an insertion hole is formed is incorporated.
In addition, the support member is held in a form in which it is positioned in contact with the upright portion, and with the support member positioned, the axial center line of the insertion hole is the rotation axis of the main body and the lid body. And the opening is opposed to the insertion hole in the extending direction of the axial center line.

In addition, when it press-processes, the curved part formed in the bending part between the bottom face of the said main body and a standing part also comprises a part of standing part of this invention. Therefore, the support member may contact only the curved portion.
The second invention is characterized in that the axial center line of the insertion hole of the support member and the center of the opening of the female member are substantially matched.

  In a third aspect of the present invention, the support member is provided with a pair of bearing portions that face each other in a direction orthogonal to the axial center line of the insertion hole. A pair of shaft holes are formed in each of the main body and the lid body, and when the main body and the lid body are combined, the shaft hole of the main body and the shaft hole of the lid body coincide with each other. The rotating support shaft that penetrates the bearing portion is inserted into the matched shaft hole.

  According to a fourth aspect of the present invention, both ends of an elastic bar member made of a single metal are used as the rotation support shaft, and the elastic bar member is bent between both ends of the rotation support shaft. A configuration in which a part contacts the support member side, the other part contacts the lid body side, the elastic force is applied to the main body and the lid body, and an elastic clamping force is exerted on the opening. It is characterized by that.

  In a fifth aspect of the present invention, the male member includes an insertion portion inserted from the opening and a latching portion that fits into the opening, and a plurality of the latching portions are formed. .

According to the first aspect, since the support member and the main body constituting the female member are separate members, the main body can be processed with a press. Therefore, the thickness of the main body can be reduced. Since the wall thickness can be reduced in this way, the weight of the stopper can be reduced.
In this way, the weight of the clasp has been reduced so that when the necklace is wrapped around the neck, the weight of the clasp prevents it from moving down around the neck, keeping the necklace in the optimal position Is done.

Moreover, since the thickness can be reduced, the amount of metal can be reduced, and the material cost can be reduced.
Furthermore, since the support member has an inner shape surrounded by the upright portion of the main body and is positioned in contact with the upright portion, the insertion of the insertion hole can be achieved simply by placing the support member inside the main body. The position is maintained.
That is, since the support member can be positioned without welding, the product assembly process can be reduced. Moreover, since it is not welded, a product with no unevenness in quality can be manufactured.

  According to the second invention, in the state where the support member is positioned, the axial center line of the insertion hole of the support member and the center of the opening of the female member can be made to substantially coincide with each other. The relative position with respect to the opening is accurately determined. That is, when the male member is inserted into the female member, the male member is reliably inserted into the support member and supported.

According to the third invention, the shaft hole of the main body and the shaft hole of the lid body coincide with each other, and the rotation support shaft penetrating the bearing portion is inserted into the coincident shaft hole. The rotation support shaft restricts the vertical movement of the support member.
Therefore, the support member does not move in the up / down / left / right and front / rear directions, so that the support member can maintain an intended position in the main body.

According to the fourth aspect of the invention, the portion that exhibits the elastic force and the rotation support shaft are sufficient as a single member, so the number of parts can be reduced accordingly. Therefore, the parts management becomes simple and the assembly process can be reduced.
Further, since the elastic force is applied to the main body and the lid body, and the elastic holding force is exerted on the opening, the elastic member is applied to prevent the male member from being easily detached from the female member.

  According to the fifth invention, since the plurality of latching portions of the male member are formed, even when an inadvertent force is applied to the necklace and the latching portion is detached from the opening, other latching is performed. Since the portion is caught in the opening, the male member cannot be easily detached from the female member.

It is a disassembled perspective view of embodiment of this invention. It is sectional drawing seen from the front of the female member in embodiment of this invention. It is sectional drawing seen from the back of the female member in embodiment of this invention. It is a perspective view of the stopper of a prior art example. It is a disassembled perspective view of the female member of a prior art example.

1 to 3 show an embodiment of the present invention.
The fastener for jewelry according to this embodiment includes a female member 22 connected to one end of a jewelry such as a necklace and a rod-shaped male member 23 connected to the other end, as in the prior art. By inserting from one end side of the member 22, both ends of the accessory are stopped.
The female member 22 includes a main body 24 and a lid body 25. The main body 24 raises an upright portion 27 from the peripheral edge of the bottom plate portion 26, and the lid body 25 extends from the peripheral edge of the ceiling plate portion 28 to a hanging portion 29. Is drooping.

The main body 24 and the lid body 25 are formed by press molding. A pair of shaft holes 30 and 31 are formed in each of the standing portion 27 of the main body 24 and the hanging portion 29 of the lid body 25 as described above. These shaft holes 30 and 31 are made to coincide with each other when the main body 24 and the lid body 25 are combined so as to overlap each other.
Then, the rotation support shafts 32 and 33 are passed through the matching shaft holes 30 and 31, and the rotation support shafts 32 and 33 support the female member 22 and the male member 23 in a rotatable manner.

The opening recess 34 formed in the standing portion 27 of the main body 24 and the opening recess 35 formed in the hanging portion 29 of the lid body 25 are combined to constitute an opening 36 into which the male member 23 is inserted. I am doing so. The opening 36 is provided in a direction perpendicular to the rotation axis X between the main body 24 and the lid body 25.
Note that a connecting portion (not shown) for connecting an accessory such as a necklace is provided on the other end of the female member 22 opposite to the opening 36.

A support member 37 made of a member different from the female member 22 is incorporated in the female member 22 thus formed.
The support member 37 is a member incorporated inside the main body 24, and includes a base portion 38 that contacts the upright portion 27 of the main body 24, a cylindrical insertion hole 39 that supports the male member 23, A pair of bearing portions 40, 40 provided with shaft holes 42, 42 through which the rotation support shafts 32, 33 pass, and a stopper portion 41 with which the tip of the male member 23 abuts are integrally configured.

The base portion 38 positions the support member 37 by contacting the upright portion 27 in a state where the support member 37 is incorporated inside the main body 24.
In this embodiment, as shown in FIG. 2, the base portion 38 is provided with a pair of front leg portions 43, 43 on the opening 36 side, and the front leg portions 43, 43 are provided on the bottom plate portion 26 of the main body 24. Are in contact. Further, as shown in FIG. 3, a pair of rear leg portions 44, 44 are provided on the opposite side of the opening portion 36 with the rotation axis X as a boundary, and the rear portions 27, 27 facing each other are respectively provided with rear portions. The legs 44 are in contact with each other.

  The insertion hole 39 of the support member 37 has a cylindrical shape that matches the shape of the male member 23, and both ends of the cylinder are open. The insertion hole 39 maintains a relative relationship in which the opening of the insertion hole 39 faces the opening 36 of the female member 22 in a state where the support member 37 is positioned. Further, the extending direction of the straight line passing through the center of the insertion hole 39, that is, the axial center line Y, and the center of the opening 36 of the female member 22 are substantially matched.

As described above, since the opening 36 and the opening of the insertion hole 39 coincide with each other, the male member 23 can be accurately inserted from the opening 36 of the female member 22 toward the insertion hole 39. That is, when the male member 23 is inserted into the female member 22, the male member 23 can be guided to the inside. Further, the male member 23 is reliably inserted into the insertion hole 39 and supported.
The opening 36 of the female member 22 may be provided at least in the extending direction of the axial center line Y of the insertion hole 39.

  Further, the pair of bearing portions 40, 40 are erected from the base portion 38, and in a state where the support member 37 is positioned, the shaft holes are located at positions corresponding to the shaft holes 30, 30 formed in the body 24. 42, 42 are formed.

The elastic rod member B, which will be described later, is provided between the pair of bearing portions 40, 40, the rotation support shafts 32, 33 pass through the shaft holes 42, 42 of the bearing portions 40, 40, and The shaft holes 30 and 30 of the main body 24 pass through the shaft holes 31 and 31 of the lid body 25. And the said main body 24, the said cover body 25, and the said supporting member 37 are connected.
Thus, since the support member 37 is attached to the female member 22 via the rotation support shafts 32 and 33, the support member 37 can hold the male member 23 at a predetermined position.

The stopper portion 41 stands from the base portion 38 and faces the opening 36 on the opposite side, and is provided in the extending direction of the axial center line Y of the insertion hole 39. When the male member 23 is inserted from the opening 36, the male member 23 passes through the insertion hole 39 and the tip of the male member 23 comes into contact with the stopper portion 41.
Since the distal end of the male member 23 abuts on the stopper portion 41, the male member 23 is not excessively inserted into the female member 22. That is, the female member 22 can be prevented from being damaged by inserting the male member 23 into the female member 22 deeply.

This embodiment is characterized in that the support member 37 is a separate member from the female member 22, while the support member 37 can be easily positioned.
The support member 37 can be positioned by bringing the base portion 38 into contact with the upright portions 27 and 27 in a state of being incorporated inside the main body 24. In this state, the relative position between the insertion hole 39 of the base portion 38 and the opening portion 36 is accurately determined.

Further, since the support member 37 is also positioned by the rotation support shafts 32 and 33, the vertical movement of the support member 37 and the movement of the rotation support shafts 32 and 33 in the direction perpendicular to the axial direction. Are regulated.
Therefore, since the support member 37 does not move in the up / down / left / right and front / rear directions, the support member 37 can maintain an intended position in the main body 24.

  As described above, the insertion hole 39 faces the opening 36 of the female member 22, and the axial center line Y of the insertion hole 39 substantially coincides with the center of the opening 36 of the female member 22. It is assembled while maintaining the positional relationship. Therefore, the male member 23 can be guided to the inside when the male member 23 is inserted into the female member 22 simply by incorporating the support member 37 inside the main body 24. Further, the male member 23 is reliably supported by the insertion hole 39.

  The rotation support shafts 32 and 33 as described above are composed of one elastic bar member B. The one elastic rod member B has both ends serving as rotation support shafts 32 and 33, and coil rotation portions 45 and 46 that exert a spring force in the torsional direction are continuously provided on the rotation support shafts 32 and 33. Yes. Further, the coil spring portions 45 and 46 are continuous via a concave ceiling plate pressure contact portion 47 that contacts the bottom plate portion 26.

Further, both ends of the ceiling plate pressure contact portion 47 are connected to the rotation support shafts 32 and 33 via a pair of bottom plate pressure contact portions 48 and 49 in a loop shape.
Then, when the rotation support shafts 32 and 33 are passed through the shaft holes 30 and 31 and the main body 24 and the lid body 25 are rotatably combined, the bottom plate pressure contact portions 48 and 49 and the ceiling plate pressure contact are obtained. The bottom plate pressure contact portions 48 and 49 press the bottom plate portion 26 through the base portion 38 while the coil spring portions 45 and 46 are bent with the portion 47, and the ceiling plate pressure contact portion 47 presses the ceiling plate portion 28 with pressure. doing. As described above, when the bottom plate pressure contact portions 48 and 49 and the ceiling plate pressure contact portion 47 are pressed against the bottom plate portion 26 or the ceiling plate portion 28 while bending the coil spring portions 45 and 46, the opening 36 is opened. Elastic force in the direction of reducing the diameter is applied.

  Therefore, when the male member 23 is pushed through the opening 36, the main body 24 and the lid body 25 rotate in a direction to open the opening 36 against the elastic force of the coil spring portions 45 and 46. And if the said male member 23 is pushed in until the latching parts 52 and 53 of the said male member 23 mentioned later correspond to the said opening part 36, the said main body 24 and the said cover body 25 will close the said opening part 36 part. And the peripheral edge of the opening 36 is hooked on the hooks 52 and 53. Thus, if the periphery of the opening 36 is hooked on the hooks 52 and 53, the male member 23 will not come out of the female member 22, and both ends of a jewelry such as a necklace are connected.

As described above, since the elastic force is applied to the main body 24 and the lid body 25, the opening portion 36 sandwiches the hook portions 52 and 53, and the male member 23 can be easily moved from the female member 22. I can't escape.
Further, if the main body 24 and the lid body 25 are rotated against the elastic force of the coil spring portions 45 and 46 in the above state, the opening portion 36 is opened, so that the male member 23 is moved to the female member. 22 can be pulled out.

  On the other hand, the male member 23 has a rod-like shape as shown in FIG. 1, and is provided with a connection portion 50 whose one end is connected to an end such as a necklace and the other end on the opposite side. The insertion portion 51 is inserted into the female member 22. Further, between the connection portion 50 and the insertion portion 51, hook portions 52 and 53 that are hooked on the opening portion 36 are formed. The latching portions 52 and 53 are formed with an annular groove in a tapered shape, and the two latching portions 52 and 53 are made continuous.

Thus, since the double latching portions 52 and 53 are formed on the male member 23, when the necklace is used, for example, an inadvertent force is applied to cause the latching portion 52 to be the female member 22. Even when the opening 36 is disengaged from the other opening 36, the opening 36 is caught by the other hook 53. For this reason, the accessory cannot be removed carelessly.
The insertion portion 51 has a shape that is tapered toward the distal end. Moreover, in this embodiment, although the shape of the said male member 23 is made into the rod shape, plate shape may be sufficient. The shape of the male member 23 is not particularly limited.

  When the male member 23 is inserted into the female member 22 from the opening 36 of the female member 22 while being pushed open between the opening recesses 34 and 35 against the elastic force, the insertion portion 51 is inserted into the insertion hole 39. Is done. When the male member 23 continues to be inserted, the opening 36 and the second latching portion 53 are latched by the elastic force of the elastic rod member B, and the male member is removed from the female member 22. 23 cannot be removed. Further, when the male member 23 is inserted deeply into the female member 22, the distal end of the male member 23 is brought into contact with the stopper portion 41 and the insertion is stopped. At this time, the insertion portion 51 of the male member 23 is supported by the insertion hole 39 of the support member 37. Then, the opening 36 and the first latching portion 52 are latched, and the male member 23 is latched to the female member 22.

Thus, since the insertion part 51 is supported by the insertion hole 39, the male member 23 is stably supported in the female member 22. If the insertion hole 39 is not provided, the male member 23 is not stabilized in the female member 22 and swings at the opening 36. When the male member 23 swings around the opening 36, the male member 23 may open the opening 36 with the male member 23, and the male member 23 may be easily detached from the female member 22. .
Therefore, the insertion hole 39 prevents the latching portions 52 and 53 from coming off from the opening 36 so that an excessive load is not applied to the opening 36.

In the accessory fastener according to the above-described embodiment, the axial center of the opening 36 and the insertion hole 39 substantially coincide with each other only by incorporating the support member 37 into the main body 24 of the female member 22. There is no need to mold them together. Therefore, the main body 24 can be a press-molded body, and only the support member 37 can be made of a casting.
Moreover, since the female member 22 can be made into a press-molded body as described above, its thickness can be reduced. If the wall thickness can be reduced in this way, the weight of the stopper can be reduced.
Accordingly, since the weight of the stopper is lightened, the necklace is not rotated by the weight of the stopper, and the necklace is maintained in an appropriate position.

Further, since the thickness can be reduced, the amount of metal can be reduced, so that the material cost can be suppressed.
Furthermore, since the support member 37 can be positioned without welding, the assembly process of the product can be reduced. Moreover, since it is not welded, a product with no unevenness in quality can be manufactured.

  In addition, in this embodiment, the elastic bar member B has only a single member for the portion that exerts the elastic force and the rotation support shafts 32 and 33, so that the number of parts can be reduced accordingly. Therefore, the parts management becomes simple and the assembly process can be reduced.

Other Embodiments The shape of the main body 24 and the lid body 25 and the shape of the support member 37 are not limited to the shape of this embodiment as long as the features of the present invention can be realized. .
Further, the shape of the elastic bar member B integrally provided with the rotation support shafts 32 and 33 is not limited to that of the above-described embodiment. Of course, in the elastic bar member B, the portion that exerts the elastic force and the rotation support shafts 32 and 33 can be provided as separate members. Further, the elastic bar member B may have any shape as long as an elastic force can be applied between the main body 24 and the lid body 25 in the closing direction of the opening 36.
