Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to fasteners for accessories such as necklaces, and more particularly to an improvement in fasteners for accessories using magnets.

[0002]

2. Description of the Related Art As a conventional fastener (a so-called clasp) for a necklace such as a pearl, a pair of detachable fastener parts (metal parts) is attached to an end of the necklace, and one of the fastener parts is, for example, folded back. An insertion tongue made of a leaf spring is provided, a release knob is provided on a part of the insertion tongue, and the other fastener part is engaged with, for example, the insertion tongue. A device provided with a receiving portion is known. According to this type, when wearing a necklace,
The insertion tongue of the other fastener component is inserted and locked into the lock receiving portion of one fastener component, and both fastener components are connected and fixed.When the necklace is removed, the release knob is pushed in. By releasing the insertion tongue from the engagement receiving portion, the insertion tongue can be released from the interior of the engagement receiving portion to release the connection and fixed state of the two fastener parts. In this type, both fastener parts do not come off unless the release knob is pushed in, so that the original fastening function of the fastener is kept stable. Further, as a conventional fastener of another type of necklace, a magnet is attached to one of a pair of fastener components, and a magnet receiving portion made of a magnetic material is provided on the other fastener component. There is also known one in which fastening parts are joined and fixed.

[0003]

However, according to the former type, the operation of inserting the tongue piece of the other fastener component into the lock receiving portion of one fastener component when the necklace is mounted. Although it is necessary, the operation itself of inserting the insertion tongue toward the correct position of the locking receiving portion is troublesome and difficult for some users. Further, when removing the necklace, two operations of pulling out the other fastener part from one fastener part while pushing the release knob must be performed at the same time, which makes the necklace removal operation troublesome. There is a technical problem that. At this time, if the release knob is designed to be small, the release knob will bite into the finger at the time of operation, and the pushing operation by the finger will be difficult to perform, and the above-described technical problem will become more remarkable. Conversely, if the release knob is designed to be large, the operability is improved to some extent, but the operation knob stands out as an external projection of the fastener, and there is a concern that the design of the fastener is hindered.

In the latter type (magnet-using type), since the magnet is certainly guided and attracted to the magnet receiving portion, the mounting operation of the two fastener parts becomes relatively easy. May. However, in order to stabilize the original fastening function of the fastener, it is necessary to set the magnetic force of the magnet to a certain degree, but if the magnetic force of the magnet is set too high, the operating force when detaching the two fastener parts becomes improper. It becomes bulky as necessary, and the operation of removing the fastener becomes difficult. Further, with respect to the conventional fastener using a magnet, the fastener component provided with the magnet is provided with a base member for mounting the magnet, and is exclusively provided on the surface of the fastener component provided with the magnet receiving portion. Since the mainstream was to design the side, the degree of freedom in the design of the fastener was extremely restricted.

[0005] Such technical problems are not limited to necklaces, but also occur with fasteners of other accessories.

SUMMARY OF THE INVENTION The present invention has been made to solve the above technical problems, and has improved the attaching / detaching operability while further stabilizing the retaining function, which is an essential function, and further improved the design. It is an object of the present invention to provide a fastener for a jewelry accessory.

[0007]

That is, as shown in FIG. 1 (a), the present invention relates to a fastener for attaching and detaching an accessory N, which comprises a pair of detachable fasteners having at least a non-circular joint at a joint section. One of the first fastening parts 1 comprising parts 1 and 2
And a guide magnet 4 is provided on the protruding end side of the engaging projection 3 so as to be substantially at the center of the other second fastener part 2. Is the engaging projection 3
Is provided with an engaging concave portion 6 rotatably fitted thereto, and a joint portion of the second fastener component 2 adjacent to the engaging concave portion 6 is attracted to a corresponding joint portion of the first fastener component 1 and is guided by the guide. Magnet 4
Characterized in that an attraction / repulsion magnet 7 for repelling the magnet is provided.

[0008] In such technical means, the shape of the fastener parts 1 and 2 and the form of the outer surface portion (front surface portion, back surface portion) other than the joint portion may be arbitrarily selected.
At least the requirement that the cross section of the joint be non-circular is required. This is because when the pair of fastener components 1 and 2 are removed, an operation of relatively rotating the pair of fastener components 1 and 2 is performed as described later. This is for enabling the attraction / repulsion magnet 7 to move to a position where the attraction effect by the magnetic force is small, preferably a position where the attraction effect is small, with respect to the joint portion of the first fastener component 1.

The structure of the joining portion adjacent to the engaging projection 3 of the first fastener component 1 may be appropriately selected as long as the attraction / repulsion magnet 7 of the second fastener component 2 is attracted. For example, a member (a plate or a block) made of a magnetic material may be provided. However, in order to keep the joining stability of the two fastener components 1 and 2 more favorable, the first fastener component 1 needs to be engaged. It is preferable to provide an attraction magnet 5 that can be attracted to the attraction / repulsion magnet 7 at a joint portion adjacent to the mating projection 3. Furthermore,
The engagement projection 3 of the first fastener component 1 and the engagement recess 6 of the second fastener component 2 may be arbitrarily selected as long as they can be fitted together. In order to keep the joining state of 1 and 2 good, it is necessary that the depth dimension of the engaging concave portion 6 is equal to or greater than the projecting dimension of the engaging convex portion 3.

Further, the guide magnets 4 provided on the engaging projections 3 may be fixed to the projecting ends of the engaging projections 3 or provided at the tips of the engaging projections 3. The guide magnet 4 may be embedded in the recessed portion. In the latter embodiment, the end of the guide magnet 4 does not necessarily need to be located at the projecting end of the engaging projection 3, and the end position of the guiding magnet 4 is set to the projecting end of the engaging projection 3. Of course, it may be retracted. The arrangement of the attraction / repulsion magnet 7 may be any position as long as it is disposed at the joint adjacent to the engaging recess 6. However, considering the joining stability, the engaging recess 6 may be provided. It is preferable to provide a pair at the joints adjacent to both sides of the.

Further, in the present invention, it is not necessary to provide anything at the bottom of the engaging recess 6 of the second fastener component 2. An auxiliary magnet 8 that can be attracted to the guide magnet 4 may be provided at the bottom. According to this aspect, by the attraction between the auxiliary magnet 8 and the guide magnet 4, it is possible to more smoothly guide the fitting convex portion 3 to the engaging concave portion 6. here,
The magnetic force of the auxiliary magnet 8 may be appropriately selected within a range in which the detaching force when the two fastener parts 1 and 2 are detached does not become unnecessarily large.

Further, for example, an auxiliary magnet 9 that can repel the guide magnet 4 may be provided at the bottom of the engaging recess 6 in the second fastener component 2. According to this aspect,
When the two fastener parts 1 and 2 are disengaged from each other, the resilient property of the guide magnet 4 and the auxiliary magnet 9 causes the engagement protrusion 3 from the engagement recess 6.
Can be improved. Here, the auxiliary magnet 9
With respect to the magnetic force, the repulsive force between the auxiliary magnet 9 and the guide magnet 4 is not unnecessarily large as compared with the attracting and joining force of the fastener parts 1 and 2 by the attracting and repelling magnet 7. What is necessary is just to select suitably as long as the joining stability of the fastener parts 1 and 2 is not impaired.

Next, a method of using the fastener of the accessory according to the present invention will be described. First, when attaching the accessory N, as shown in FIGS.
2 may be brought close to each other so that the joints join. At this time, the engagement projection 3 of the first fastener component 1
Since the guide magnet 4 is provided on the protruding end side, when the guide magnet 4 of the first fastener component 1 approaches the attraction / repulsion magnet 7 at the joint of the second fastener component 2, Repel each other. For this reason, the engaging projection 3 having the guide magnet 4 is guided and inserted into the engaging recess 6 of the second fastener component 2, and the attraction / repulsion magnet 7 of the second fastener component 2 is Attachment to the joint of the fastener part 1 is attempted. As a result, the joining parts of the two fastener parts 1 and 2 are attracted and joined to each other while the engaging convex part 3 is fitted in the engaging concave part 6, and the two fastener parts 1 and 2 are joined. Fixed.

On the other hand, when the accessory N is to be removed, FIG.
(A) As shown in (c), for example, both fastener parts 1 and 2
After rotating about 90 ° relative to each other, the two fastener parts 1 and 2 may be separated from each other. At this time, FIG.
As shown in (c), when the first fastener component 1 is rotated by about 90 ° with respect to the second fastener component 2, the second fastener component 2 is rotated.
Of the attraction / repulsion magnet 7 at the joint of the first fastener part 1
Is moved to a position where the influence of the magnetic force on the joining portion is small, so that the joining and attracting force of the magnet 7 for attracting and repelling hardly works between the two fastener parts 1 and 2. In this state, if the two fastener parts 1 and 2 are separated from each other, the two fastener parts 1 and 2 are easily separated.

The same one is used as each of the magnets 8. For example, when the suction joining force at the joint portion between the two fastener parts 20, 30 is set to be stronger, the suction repulsion magnet 38 and the suction magnet 28 are used. If it is necessary to select a magnet having a stronger magnetic force, and if the operating force for removing the two fastener parts 20 and 30 is to be smaller, the guide magnet 2
6 or an auxiliary magnet 35 having a weaker magnetic force may be appropriately selected according to various requests.

Next, a method of using the fastener of the necklace according to the present embodiment will be described. First, when the necklace is worn, as shown in FIG. 3A, the fastener components 20, 30 may be brought closer to each other so that the joints 22, 32 are joined. In this state, when the engaging projection 24 of the first fastener component 20 approaches the attraction / repulsion magnet 38 of the joining portion 32 of the second fastener component 30, the guiding projection embedded in the engagement projection 24. Since the magnet 26 and the attracting / repelling magnet 38 repel each other, the engaging convex portion 24 of the first fastener component 20 is connected to the attracting / repelling magnet 38 portion of the joining portion 32 of the second fastener component 30. And is inevitably guided to the engagement recess 34. And
When the engaging convex portion 24 is guided to the engaging concave portion 34, the guide magnet 26 embedded in the engaging convex portion 24 and the auxiliary magnet 35 disposed at the bottom of the engaging concave portion 34 attract each other. To fit, the engaging projection 24 is forcibly inserted into the engaging recess 34. At the same time, the attraction repulsion magnet 38 of the second fastener component 30 and the attraction magnet 28 of the first fastener component 20 mutually attract each other, so that the joint 2 of the fastener components 20 and 30 is joined.
The magnets 2 and 32 are joined and attracted by the attracting operation of the magnets 28 and 38.

At this time, as shown in FIG. 3B, the attraction magnets 28 and the attraction / repulsion magnets 38 are not protrudingly arranged on the surfaces of the joints 22, 32 of the fastener components 20, 30, respectively. Moreover, the engaging projection 24 of the first fastener component 20 is completely inserted into the engagement recess 34 of the second fastener component 30 with a gap (dh) left between the first fastener component 20 and the auxiliary magnet 35. Since they are inserted and connected, the joints 22 and 3 of the two fastener parts 20 and 30 are connected.
Both are joined and fixed in close contact without forming a space between the two.

When removing the necklace 10,
First, with respect to the fastener 11 in the mounted state shown in FIG.
For example, as shown in FIG.
And the first fastening part 20 are relatively rotated by about 90 °, and then, as shown in FIG.
What is necessary is just to make 0, 30 separate. Now, FIG.
(B) When the first fastener component 20 is rotated about 90 ° with respect to the second fastener component 30 as shown in I, FIG.
As shown in FIG. 5, the attracting / repelling magnet 38 at the joint 32 of the second fastener component 30 is connected to the joint 2 of the first fastener component 20.
In order to move to the position where the attraction effect by the magnetic force is small with respect to the attraction magnet 28 in FIG.
Between them, the joining and attracting force of the attraction magnet and the attraction / repulsion magnet 38 hardly works. In this state, FIG.
(B) If the two fastener parts 20, 30 are separated from each other as in II, the two fastener parts 20, 30 are easily separated. At this time, the engaging projection 24 is fitted into the engaging recess 34, and the guide magnet 26 and the auxiliary magnet 35 are attracted to each other.
Although the acting force (joining attraction force) for joining 0, 30 works, as shown in FIG. 4 (a), as compared with the case where the fastener 11 is in the mounted state, the distance between the fastener components 20, 30 is increased. The bonding attraction force is only about 1/3.

Further, in the present embodiment, of the outer surface portions of the fastener components 20, 30, different designs are applied to the front surface portion and the back surface portion (for example, a matte pattern M on the front surface and a plain pattern G on the back surface). By doing so, as shown in FIGS. 5A and 5B, by exposing either the front surface portion or the back surface portion of the fastener 11, the impression of the necklace 10 at the fastener 11 is different. can do. Further, in the present embodiment, as shown in FIG.
If one of 0 and 30 is exposed on the front surface and the other is exposed on the back surface, the design of the fastener 11 can be a mixed pattern of the satin pattern M and the plain pattern G. Since the positions of the connecting rings 23 and 33 of the fastener 11 with respect to the necklace 10 can be linearly arranged, the layout of the fastener 11 with respect to the necklace 10 can also be changed.

Furthermore, the fastener 11 according to the present embodiment
Is composed of a pair of fastening parts 20, 30 having flattened hemispherical fastening bodies 21, 31, but is not limited to this. For example, as shown in FIG. Fastener body 2 obtained by cutting an elliptical body obliquely
A pair of fastener parts 20 ', 30' having 1 ', 31'
If the fastener 11 is formed by using, the shape of the fastener 11 can be used in the form of a flat elliptical body, and as shown in FIG. 6 (b), the fastener parts 20 ', 30' If it is relatively rotated by 180 °, it can be used as the heart-shaped fastener 11.

Second Embodiment FIG. 7 is an explanatory view showing a second embodiment of a fastener for an accessory to which the present invention is applied. In FIG.
As in the first embodiment, a necklace 10 as an accessory
And has a configuration basically similar to that of the first embodiment. However, a cylindrical auxiliary magnet 36 different from that of the first embodiment is provided at the bottom of the engaging recess 34 of the second fastener component 30. Is buried. The auxiliary magnet 36 is a bar magnet having an S pole on the front side, and the guide magnet 26 (in this example, a bar magnet having an S pole on the front side is used when the engaging projection 24 is fitted into the engaging recess 34). ). Embodiment 1
The same components as in the first embodiment are denoted by the same reference numerals as in the first embodiment, and the detailed description is omitted here.

Therefore, according to the fastener of the necklace according to the present embodiment, the necklace 1
When the necklace 10 is detached, the fasteners 20 and 30 may be brought closer to each other so that the joints 22 and 32 are joined. On the other hand, for example, after rotating the second fastening part 30 and the first fastening part 20 relatively by about 90 °, the two fastening parts 20, 30 may be separated from each other.

At this time, in the mounting process of the fastener 11, when the engaging projection 24 of the first fastener component 20 approaches the attraction / repulsion magnet 38 of the joint 32 of the second fastener component 30, Since the guide magnet 26 and the attracting / repelling magnet 38 embedded in the engaging projection 24 repel each other, the engaging projection 24 of the first fastener component 20 is joined to the second fastener component 30. Of the portion 32, it is pushed away from the attraction / repulsion magnet 38 and is inevitably guided to the engagement recess 34. And
When the engaging convex portion 24 is guided to the engaging concave portion 34, the guide magnet 26 embedded in the engaging convex portion 24 and the auxiliary magnet 36 disposed at the bottom of the engaging concave portion 34 repel each other. Although they are in a mating relationship, the attraction / repulsion magnet 38 of the second fastener component 30 and the attraction magnet 28 of the first fastener component 20 mutually attract each other, and the attraction magnet 28 and the attraction / repulsion magnet 38 Is larger than the repulsive force between the guide magnet 26 and the auxiliary magnet 36, so that the fastener components 20, 30
Are joined and attracted by the attracting operation of the magnets 28 and 38. For this reason, the two fastener parts 2
0 and 30 are joined and fixed in close contact.

In the process of removing the fastener 11, when the first fastener component 20 is rotated by about 90 ° with respect to the second fastener component 30, the suction at the joint 32 of the second fastener component 30 is performed. The repulsion magnet 38 is the first fastener part 2
In order to move to the position where the attraction effect by the magnetic force is small with respect to the attraction magnet 28 at the joint portion 22 of the zero, the attraction force of the attraction magnet and the attraction / repulsion magnet 38 hardly acts between the two fastener parts 20 and 30. Disappears (FIG. 4 (b)
(C)). At the same time, the engaging projection 24 is fitted in the engaging recess 34, but the guiding magnet 26 and the auxiliary magnet 36
Between the second fastening part 30
On the other hand, at the stage where the first fastener component 20 is rotated by about 90 °, a separating force is exerted between the two fastener components 20 and 30 due to the repulsive force. For this reason, the both fastener parts 20, 30 can be easily detached without actively trying to separate them in the direction in which the two fastener parts 20, 30 are separated from each other.

In this embodiment, the guide magnets 26,
The same magnets are used as the attraction magnet 28, the auxiliary magnet 36, and the attraction / repulsion magnet 38. For example, when the attraction joint force at the joint portion between the two fastener components 20, 30 is set to be stronger. In order to select a magnet having a stronger magnetic force of the attracting / repelling magnet 38 or the attracting magnet 28,
Alternatively, it may be appropriately selected according to various requests, such as weakening the magnetic force of the auxiliary magnet 36.
