Description

  In this invention, a decorative material such as a pearl or ball is connected to both ends of a jewelry such as a necklace or a bracelet made of a neck, a bracelet, or the like made of a neck, a wire, or a thread, and the accessory is made endless (annular). The present invention relates to a connector for connecting.

In general, accessories such as necklaces and bracelets are attached to the neck and arms in an endless shape, but each end must be connected or separated each time, so that it can be done easily and reliably. Various connecting devices have been conventionally provided.
Many of them are pin insertion / removal type couplers composed of a combination of a female member having an insertion hole and a male member having a protrusion that can be inserted into and removed from the insertion hole.

  For example, in Patent Document 1, a locking groove portion is formed over the entire circumference of a rod body that is a protruding portion of a male member, and the cylinder body that is a female member is biased by a spring. An open / close lever is pivotally provided, and when the rod is inserted into the cylinder, the locking claw formed at the tip of the open / close lever fits into the locking groove to connect the rod and the cylinder And the coupling tool of the structure which remove | disconnects with respect to a rod body and makes it possible to detach | leave a rod body from a cylinder body by rotating an opening-and-closing lever against an urging | biasing force is disclosed.

In addition, as seen in Patent Document 2, for example, there is a connecting tool in which a permanent magnet (magnet) is provided in each of a convex coupling portion and a concave coupling portion that are fitted to each other, and both are coupled by the magnetic force of the magnet. Proposed.
JP 2000-279219 A JP-A-8-182521

  However, since the conventional pin insertion / removal type coupler as shown in Patent Document 1 has a complicated configuration having a movable part such as an opening / closing lever, the overall size of the coupled state becomes relatively large. There were problems such as durability problems and high costs. In addition, since it is necessary to expose the movable operation part to the outside, the appearance design is impaired as a part of the accessory, and since the operation part protrudes from the outer periphery of the coupling tool, it is caught on clothes or feels bad to the touch. There was also a problem.

In addition, the coupling tool coupled by the magnetic force of the conventional magnet as shown in Patent Document 2 is magnetized so that the mutually facing surfaces of the magnets in the two coupling portions have different polarities (N pole and S pole). Even if the outer surfaces of the two connecting portions are in any relative positional relationship, they are connected. Therefore, when the pattern is given to the outer surface of the connecting part, or when the shape of the front and back surfaces are different, it will be connected even if the pattern and front and back surfaces of the two connecting parts do not match. There was a problem that looks worse.
Further, if the magnetic force of the magnet is increased so that the two connecting portions can be reliably connected, there is a problem that a large force is required when the magnets are separated.

  The present invention has been made to solve these problems, and has a simple configuration in which no movable part is provided, and can be easily and reliably connected and detached without any special operation. Moreover, it is an object of the present invention to provide a jewelery linking tool having a good appearance by ensuring that the outer surface pattern and the front and back surfaces of the garment always coincide with each other.

The jewelry accessory according to the present invention is a connector that is attached to both ends of the jewelry and connects the jewelry in an endless manner. To achieve the above object, the first accessory attached to one end and the other end of the jewelry. It consists of a connecting part and a second connecting part, and the first connecting part and the second connecting part are each a single hollow housing in the outer peripheral direction at the intermediate part of the connecting direction of the first connecting part and the second connecting part. The first housing and the second housing are cut along a straight line or a curve having irregularities.
A permanent magnet is fixed in each of the first casing and the second casing, and each permanent magnet is arranged such that one of the end portions in the direction orthogonal to the connecting direction is an N pole and the other is an S pole. The first casing and the second casing are magnetized and form the hollow casing at a connection position where different polarities (N pole and S pole) of the permanent magnet fixed in each casing face each other. It becomes the joining state which carries out.

Even if the hollow casing is a flat hollow casing having an elliptical or oval surface and a back surface that are long in the connecting direction, and the surface shape of the front surface and the back surface is different, In the two cases, the front surfaces and the back surfaces are joined at the connection position.
In that case, the first casing and the second casing may be shaped such that the flat hollow casing is cut along a line constituting a pattern on the surface thereof.

  In addition, the hollow casing has a cross-sectional shape in a direction orthogonal to the connecting direction that is point-symmetric with respect to the center thereof, and the first casing and the second casing pass through the center through the connecting direction. The relative position of the permanent magnets fixed in the respective housings is shifted from one of the connected positions where the opposite poles of the permanent magnets face each other to the other and the unconnected positions where the same poles face each other. Good.

The jewelry accessory according to the present invention has a simple configuration with no movable part, and does not require any special operation, and the first housing and the second housing serve as a guide. In fact, the permanent magnets in the casing are reliably connected by the attractive force at the connecting positions where the opposite poles face each other.
In this connection position, the first casing and the second casing are always joined to form the hollow casing, so that the outer surface pattern and the front and back surfaces always match, and the first connection portion and the second connection The part looks like one member, and looks good as an accessory.
Further, if the first connecting portion and the second connecting portion are relatively rotated in the direction of the non-connecting position where the same polarity of the permanent magnets in the respective housings face each other, the attractive force is weakened so that they can be easily separated. it can.

Preferred embodiments of the present invention will be specifically described below with reference to the drawings.
[First embodiment: FIGS. 1 to 7]
First, a first embodiment of a jewelry accessory according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a state in which accessories are connected by the connecting tool, FIG. 2 is a plan view of only the connecting tool, and FIG. 3 is a back view. 4 is a plan view showing a state in which the first connecting portion and the second connecting portion of the connector are separated from each other, FIG. 5 is a cross-sectional view taken along line XX of FIG. 4, and FIG. 6 is a second connection in FIG. It is the figure which looked at the part from the arrow P direction. FIG. 7 is a view similar to FIG. 6 showing different magnetizing examples of the magnet.

In FIG. 1, as an example of the accessory 2, a large number of pearls 2 a having a uniform grain are attached to both ends of the necklace connected to each other through a thin chain 2 b, and the accessory 2 is endless (annular). The connector 1 connected to is shown.
The connecting tool 1 includes a first connecting portion 1A for locking a chain 2b at one end (right side in FIG. 1) of the accessory 2 by a locking ring 12, and a chain 2b at the other end (left side in FIG. 1) of the accessory 2. It consists of the 2nd connection part 1B latched by the latching ring 22. FIG.

The first connecting portion 1A and the second connecting portion 1B are respectively connected to a single hollow casing as shown in FIGS. 1 to 3 in the connecting direction of the first connecting portion 1A and the second connecting portion 1B (these drawings). In this embodiment, the first housing 10 and the second housing 20 are cut along a straight line (in this embodiment, a V-shaped straight line) having irregularities in the outer peripheral direction at the middle portion thereof.
In this embodiment, the single hollow casing before cutting is a flat hollow casing having an oblong surface and a back surface that are long in the connecting direction, and the surface shapes of the front surface and the back surface are different.

  That is, as shown in FIGS. 1 and 2, the surface has a curved surface in which each fan-shaped portion divided into four by a cross-like straight line is slightly raised upward in the center. The back surface is flat, as shown in FIG. 3, the dividing line between the first housing 10 and the second housing 20, stop pins 14 and 24 for fixing magnets 15 and 25, which will be described later, Only the bosses 13 and 23 that are recessed so that each part does not protrude are visible.

Therefore, the first housing 10 and the second housing 20 of this embodiment are arranged along the imaginary line a− shown in FIG. 2 along the line that the flat hollow housing shown in FIG. It has a cut shape like bc.
Slots 11 and 21 are formed on the side surfaces of the first casing 10 and the second casing 20 along the elliptical direction, respectively, to enhance decorativeness and reduce the weight. Locking rings 12 and 22 are attached to the vertical frame portions between the slots located at both ends of the long axis direction of the ellipse.

  As shown in FIGS. 4 and 5, magnets 15 and 25, which are rectangular parallelepiped permanent magnets, are disposed in the first housing 10 and the second housing 20 so that one end surfaces thereof face each other. The fixing pins 14 and 24 are fixed from the back side. Each of the magnets 15 and 25 has one end of the direction orthogonal to the connecting direction of the first connecting portion 1A and the second connecting portion 1B (the direction indicated by the alternate long and short dash line in FIG. 4), and the other is the S pole. It is magnetized to become. In this embodiment, as shown in FIGS. 5 and 6, both end portions in the thickness direction of the magnets 15 and 25, which are also in the height (thickness) direction of the first housing 10 and the second housing 20, serve as magnetic poles. The magnet 15 of the first connecting part 1A is magnetized with the N pole at the upper end and the S pole at the lower end, and the magnet 25 of the second connecting part 1B is magnetized with the S pole at the upper end and the N pole at the lower end. ing.

When connecting the first connecting portion 1A and the second connecting portion 1B of the connector 1 from a separated state as shown in FIG. 4, it corresponds to the cut surfaces of the first housing 10 and the second housing 20. The joining surfaces 10a and 20a to be performed serve as a guide, and the first housing 10 and the second housing 20 cannot be fitted unless the front and back surfaces are in substantially the same direction. In addition, if the front and back surfaces of the first housing 10 and the second housing 20 are reversed, the same poles of the magnets 15 and 25 are opposed to each other even if they are fitted halfway. Since it is not adsorbed, it cannot be combined.
Therefore, the first housing 10 and the second housing 20 are always joined at the connecting positions where the opposite poles of the magnets 15 and 25 fixed inside face each other to form a hollow housing. In this state, the first connecting portion 1A and the second connecting portion 1B are reliably connected.

  Therefore, if this connecting tool 1 is used, the first connecting part 1A and the second connecting part 1B can be connected easily and reliably even when the accessory 2 is connected by groping on the back side of the neck, etc. Since the front and back of the first connecting part 1A and the second connecting part 1B are not reversed, there is no problem even if the shapes of the front and back surfaces are different, even if the outer surface has a pattern or the like. In the state, it appears as a continuous pattern of the entire connector 1.

  The magnets 15 and 25 in the first housing 10 and the second housing 20 are magnetized so that magnetic poles are generated at both ends in a direction orthogonal to the connecting direction of the first connecting portion 1A and the second connecting portion 1B. Therefore, as shown in FIG. 7, the magnet 25 in the second housing 20 is magnetized so that both end portions in the short direction (width direction) are N-pole and S-pole, and the first housing 10 The inner magnet 15 generates magnetic poles at both ends in the short direction (width direction) so that the opposite poles face the magnet 25 when the first housing 10 and the second housing 20 are properly joined. You can do it.

Nonmagnetic metal is used as the material of the first housing 10 and the second housing 20, but since the connector 1 forms a part of the accessory 2, for example, it is formed of silver and nickel on the surface. It is recommended to use rhodium plating or use precious metals such as 18 gold and white gold.
The surfaces of the magnets 15 and 25 may be subjected to nickel plating or the like as a rust preventive treatment in order to improve corrosion resistance and breakage resistance.

[Modification]
The hollow casing that is the basis of the first casing and the second casing is not limited to an ellipse, but may be an oval shape, a chamfered rectangle, a rhombus, an asymmetric shape such as an egg shape, or the like. Further, the shape is not limited to a flat shape, and may be a cylindrical shape or a capsule shape of a square tube.
The cutting line that divides the hollow housing into the first housing and the second housing is the outer peripheral direction (the outer periphery in the short direction) at the intermediate portion in the connecting direction (longitudinal direction) between the first connecting portion and the second connecting portion. (A direction along the line) may be a straight line or a curve having irregularities.

[Second Embodiment: FIGS. 8 to 10]
Accordingly, a second embodiment of the jewelry accessory according to the present invention will be described with reference to FIGS. 8 is a perspective view showing a state immediately before the accessory is connected by the accessory connector, FIG. 9 is a plan view showing only the connector connected by the first connecting part and the second connecting part, and FIG. It is the figure which looked at the 1st connection part from the connection direction.

This connecting tool 3 also includes a first connecting part 3A for locking a chain (not shown) of one end (right side in FIG. 8) of the accessory 2 connected to the pearl 2a by a locking ring 32 (see FIG. 9), The second connecting portion 3B is configured to lock the end (left side in FIG. 8) chain by the locking ring 42.
As shown in FIG. 9, each of the first connecting portion 3A and the second connecting portion 3B constitutes a single cylindrical capsule-shaped hollow casing in the connecting direction (longitudinal direction) of the first connecting portion 3A and the second connecting portion 3B. The first casing 30 and the second casing having a shape cut along a curve L1 having a concavo-convex shape in the outer peripheral direction (the direction along the outer periphery in the short direction) L1. It has a body 40.

  Therefore, the joining surfaces 30a and 40a shown in FIG. 8 of the first housing 30 and the second housing 40 are curved surfaces whose concavo-convex states are opposite to each other. Magnets 35 and 45, which are rectangular parallelepiped permanent magnets, are also fixed in the first casing 30 and the second casing 40, respectively, such that one end faces thereof are opposed to each other. Each of the magnets 35 and 45 is magnetized so that one of both end portions in the direction orthogonal to the connecting direction (longitudinal direction) of the first connecting portion 3A and the second connecting portion 3B is an N pole and the other is an S pole. Thus, when the first housing 30 and the second housing 40 are correctly joined, the different polarities of the magnets 35 and 45 face each other and attract each other.

  In this embodiment, a guide shaft hole 36 is formed in the center of the end surface of the first connecting portion 3A facing the magnet 45 of the magnet 35 in the direction of the central axis of the first housing 30, and the second connecting portion 3B. A guide shaft 46 projects from the central portion of the end surface of the magnet 45 facing the magnet 35 in the direction of the center axis of the cylinder of the second housing 40 so that they can be fitted to each other so as to be relatively rotatable. If the tip end portion of the guide shaft 46 has a slightly tapered surface, insertion into the guide shaft hole 36 is facilitated.

  Therefore, when connecting the first connecting portion 3A and the second connecting portion 3B of the connecting tool 3 from a separated state, first, the guide shaft 46 of the first connecting portion 3A is moved to the guide shaft hole of the second connecting portion 3B. When the first connecting portion 3A and the second connecting portion 3B are rotated relative to each other around the guide shaft 46, the first housing 30 is connected at the connecting position where the magnets 35 and 45 are opposite to each other. And the joining surfaces 30a and 40a of the second housing 40 are correctly joined and securely connected.

  When it is desired to unlink the first connecting portion 3A and the second connecting portion 3B, if the first connecting portion 3A and the second connecting portion 3B are relatively rotated from the connecting position, the different polarities of the magnet 35 and the magnet 45 are separated. As the protrusions of the joint surfaces 30a and 40a of the first casing 30 and the second casing 40 come into contact with each other, the first casing 30 and the second casing 40 are separated from each other, and the magnet 35 Since the magnet 45 is also separated, the attractive force is weakened and the connection can be easily released. When the first connecting portion 3A and the second connecting portion 3B are rotated by 180 degrees relative to the connecting position, the first and second connecting portions 3A and 3A are connected to each other by reversing the same polarity of the magnet 35 and the magnet 45. The part 3B can be completely separated.

  As described above, the first casing 30 and the second casing 40 are rotated relative to each other around the axis along the connecting direction of the first connecting portion 3A and the second connecting portion 3B through the center thereof, thereby allowing each casing to be rotated. It is possible to shift from one of the coupling position where the opposite poles of the magnets 35 and 45 fixed in the 30 and 40 face each other and the non-coupling position where the same pole faces each other to the other.

[Third embodiment: FIGS. 11 and 12]

FIG. 11 is a plan view showing the accessory connector in a state where the first connecting portion and the second connecting portion are connected, and FIG. 12 is a view of the first connecting portion as seen from the connecting direction.

This connecting tool 4 also includes a first connecting part 4A attached to one end of an accessory not shown, and a second connecting part 4B attached to the other end of the accessory.
As shown in FIG. 11, the first connecting portion 4A and the second connecting portion 4B form a single octagonal cylindrical capsule-shaped hollow casing in the connecting direction (longitudinal direction) of the first connecting portion 4A and the second connecting portion 4B. A straight line having irregularities in the outer peripheral direction (the direction along the outer periphery in the short direction) in the middle part of the direction) (in this embodiment, the cross section is a zigzag straight line in which the inclination direction is inverted for each side of the octagon) along L2 It has the 1st housing | casing 50 and the 2nd housing | casing 60 of the shape which cut | disconnected.

Magnets 55 and 65, which are rectangular parallelepiped permanent magnets, are also fixed in the first casing 50 and the second casing 60 so that one end faces thereof are opposed to each other. The magnetized states of the magnets 55 and 65 are the same as those of the magnets 35 and 45 of the second embodiment described above.
Also in this embodiment, the guide shaft hole 56 is formed in the central portion of the end face of the first connecting portion 4A facing the magnet 65 of the magnet 55 in the direction of the central axis of the first casing 30, and the second connecting portion. A guide shaft 66 protrudes from the central portion of the end surface of the 4B magnet 65 facing the magnet 55 in the direction of the central axis of the second casing 60 so that they can be fitted to each other so as to be relatively rotatable.

Also in this embodiment, the case where the first connecting portion 4A and the second connecting portion 4B of the connector 4 are connected and the operation method and function when the connection is released are the same as those in the second embodiment described above. Is omitted.
Further, by rotating the first casing 50 and the second casing 60 about the axis along the connecting direction of the first connecting portion 4A and the second connecting portion 4iB through the center thereof, the respective casings 50, Similarly to the second embodiment, the magnets 55 and 65 fixed in the 60 can be shifted from one of the connecting position where the different poles of the magnets 55 and 65 are opposed to each other and the non-connected position where the same poles face each other.
In the case of this embodiment, when the first casing 50 and the second casing 60 are relatively rotated, a click feeling is obtained each time the first casing 50 and the second casing 60 are rotated by 45 degrees.

[Matters common to the second and third embodiments]

The cross-sectional shape in the direction orthogonal to the center may be a shape that is point-symmetric with respect to the center.

Although a guide shaft hole and a guide shaft fitted to the guide magnet hole are provided in the central portion of the square magnet fixed to the first housing and the second housing, the first connecting portion and the second connecting portion are easily rotated relatively. This is not essential, and even without these, the first connecting portion and the second connecting portion can be reliably connected at a predetermined relative position, and the first connecting portion and the second connecting portion can be connected from the connected state. By relatively rotating around the central axis, the connection can be easily released.
