Therefore, the second plug 20 has the same configuration as the first plug 10. However, in the second insertion body 20, the direction in the D direction is opposite to that of the first insertion body 10. The second plug 20 may have a different configuration from the first plug 10. For example, the second base portion 20A may have a configuration different from that of the first base portion 10A, and the second ferromagnetic portion 20B may have a configuration different from that of the first ferromagnetic portion 10B.

3A and 3B show the main body 30, FIG. 3A is a cross-sectional view taken along the line AA of FIG. 1B, FIG. 3B is a view seen in the −D direction, and FIG. 3C is B of FIG. 1B. -It is a cross-sectional view along line B. As shown in FIG. 3, the main body 30 has a spherical outer shape, and has a first insertion port 31, a second insertion port 32, and an insertion hole 33 as described above. The first insertion port 31 is formed at the end of the main body 30 on the + D side, and its opening shape is circular. The second insertion port 32 is formed at the end portion of the main body 30 on the −D side, and is formed to have the same shape and size as the first insertion port 31. The insertion hole 33 is a hole that penetrates the main body 30 in the D direction, and is formed so as to extend in the D direction from each of the first insertion port 31 and the second insertion port 32. Further, the insertion hole 33 is formed so as to overlap the through hole 43 in the D direction view, and is a hole having a constant diameter from the first insertion port 31 to the second insertion port 32 and having a circular cross section. be.

The first insertion port 31 is formed to be smaller than the outer shape of the gem 61a at one end side of the decorative portion 60 when viewed from the D direction (see FIG. 5C). The second insertion port 32 is formed to be smaller than the outer shape of the gem 61b at the other end of the decorative portion 60 when viewed from the D direction (see FIG. 5D). The main body 30 includes a magnetic force suction portion 40 and a main body portion 50 having the first insertion port 31 and the second insertion port 32 described above.

The magnetic attraction attracting portion 40 is, for example, a magnet such as an alloy magnet containing iron as a main component, a ferrite magnet, or a neodymium magnet, and attracts the first ferromagnetic portion 10B and the second ferromagnetic portion 20B by the magnetic force thereof. The magnetic force suction portion 40 is formed in an annular shape (ring shape) in the D direction view. Further, the magnetic force attraction unit 40 is magnetized along the thickness direction (D direction). For example, the + D side portion 41 of the magnetic force attraction unit 40 is the N pole, and the −D side portion of the magnetic force attraction unit 40. 42 is the S pole. The magnetic force attracting portion 40 may be magnetized in a direction different from the thickness direction, for example, in the radial direction (that is, the direction orthogonal to the D direction), instead of the one magnetized in the thickness direction. do not have.

The magnetic force suction unit 40 has a through hole 43. The through hole 43 is a hole having a constant diameter from the end on the −D side to the end on the + D side and having a circular cross section. The through hole 43 penetrates the central portion of the magnetic force attracting portion 40 in the D direction in the D direction. Further, the through hole 43 constitutes a part of the insertion hole 33, and is formed so that the first insertion body 10 and the second insertion body 20 can be inserted and removed in the D direction. That is, the inner peripheral surface 44 of the through hole 43 is also a part of the inner peripheral surface 33a of the insertion hole 33. The magnetic force attracting portion 40 can be formed into various shapes as long as it has a shape having a through hole 43, and may be, for example, a spherical shape or a prismatic shape instead of the above-mentioned annular shape. Further, the through hole 43 is not limited to the above configuration, and instead of having a circular cross section, a hole having a polygonal cross section may be used, for example, from the end portion on the −D side to the end portion on the + D side. Those having different diameters may be used.

The main body portion 50 has a spherical outer shape, and holds the magnetic force suction portion 40 in the central portion thereof. The main body portion 50 is formed, for example, by attaching a plurality of parts (for example, a pair of hemispherical parts) to the surface of the magnetic force attracting portion 40. Further, the main body portion 50 has through holes 51a and 51b having a circular cross section penetrating in the D direction. The through hole 51a is formed so as to extend in the + D direction from the first insertion port 31. The through hole 51b is formed so as to extend in the −D direction from the second insertion port 32. Further, the through holes 51a and 51b are formed so as to overlap the inner peripheral surface 44 of the through hole 43 in the D direction view, and together with the through hole 43, form the insertion hole 33 of the main body 30. Further, the inner peripheral surfaces 52a and 52b of the through holes 51a and 51b together with the inner peripheral surface 44 of the magnetic force attracting portion 40 form the inner peripheral surface 33a of the insertion hole 33. The main body 50 is a non-magnetic material, and is formed of, for example, a metal such as copper or aluminum, a resin such as acrylic or plastic, wood, or a jewel.

Various configurations can be applied to the main body 50 as long as it does not affect the connection between the first insertion body 10 and the second insertion body 20 by magnetic force. For example, the main body 50 may be a ferromagnetic material. I do not care. Further, the shape of the main body portion 50 is not limited to a spherical shape, and various shapes such as a prismatic shape, a cylindrical shape, a heart shape, and a skull (skull) shape can be applied. Further, the main body portion 50 may be configured to cover the inner peripheral surface 44 of the through hole 43.

The main body 30 is not limited to the above configuration, and can be formed into a desired shape as long as the magnetic force suction portion 40 has a through hole 43 and has a first insertion port 31 and a second insertion port 32. For example, the main body 30 is configured to include both the magnetic force suction unit 40 and the main body 50, but may be composed of only the magnetic force suction unit 40. In such a case, the first insertion port 31 is formed at the position of the end portion on the −D side of the through hole 43, and the second insertion port 32 is formed at the end portion 43a on the + D side of the through hole 43.

The connection mode of the clasp 1 with the decorative portion 60, and the operation of connecting and disconnecting the clasp 1 will be described later.

According to the clasp 1 of the first embodiment, since there are few structural restrictions on the main body 30, the external design thereof can be designed more freely. As a result, the user can enjoy the desired design. Further, according to the clasp 1, both the first insertion body 10 and the second insertion body 20 can be removed by simply pulling out the first insertion body 10 and the second insertion body 20 from the main body 30 against the magnetic force. It is separable from the main body 30. As a result, the user replaces the main body 30 with a different design without replacing the first plug 10 and the second plug 20 (for example, replace the main body 30 from a spherical one to a skull-shaped one). The external design of the clasp 1 can be easily changed, and various designs can be easily enjoyed.

<Second Embodiment>
Next, an example of the accessory 100 according to the second embodiment will be described with reference to the drawings. In the description of the second embodiment, the same or equivalent components as those of the first embodiment described above are designated by the same reference numerals, and the description thereof will be omitted or simplified.

4A and 4B are side views of a main part showing an example of the accessory 100, in which FIG. 4A shows a state in which the clasp 1 is disconnected, and FIG. 4B shows a state in which the clasp 1 is connected, that is, a state at the time of use. ing. The accessory 100 is a ring-shaped accessory, for example, a necklace. As shown in FIG. 4, the accessory 100 includes a clasp 1 and a decorative portion 60. The clasp 1 is used as a fastener in the accessory 100.

The decorative portion 60 has a structure in which a plurality of gems are braided in a series, and has a plurality of gems 61 articulated in the series and an articulated thread 62 (see FIG. 2C). The gem 61 is, for example, a pearl, a jewel, a bead, or the like. The gem 61 has an outer shape larger than the openings of the first insertion port 31 and the second insertion port 32 of the main body 30. Further, the gem 61 has an insertion hole 61c through which the connecting thread 62 can be inserted. The insertion portion 11 of the first insertion body 10 is inserted into the gem 61a at the end portion on one end side (−D side) of the decoration portion 60. The insertion portion 11 of the second insertion body 20 is inserted into the gem 61b at the other end side (+ D side) of the decorative portion 60. The articulating thread 62 is sequentially inserted into the insertion holes 61c of the plurality of gems 61 constituting the decorative portion 60, inserted into the holes 11d of the insertion portion 11, and then folded back in the opposite direction. In this way, a plurality of gems 61 are connected via the connecting thread 62, and the first insertion body 10 and the second insertion body 20 are attached to the gems 61a and 61b at the ends, respectively. Further, due to the tension of the connecting thread 62, the surface 12a on the −D side of the connecting portion 12 of the first insertion body 10 is in contact with the surface 61d of the gem 61a. Similarly, the + D side surface of the connecting portion 12 of the second insertion body 20 is in contact with the surface of the gem 61b. As described above, the plurality of gems 61, the first insertion body 10, and the second insertion body 20 are configured in a series and integrally via the connecting thread 62.

As described above, in the accessory 100, one end of the decorative portion 60 is connected to the first insertion body 10, and the other end of the decoration portion 60 is connected to the second insertion body 20. Then, when the clasp 1 is connected, the accessory 100 becomes an endless ring as shown in FIG. 4 (b). The user uses the accessory 100 in a state where the clasp 1 is connected and the decorative portion 60 is connected in a ring shape in this way. In such a state of use, the main body 30 is a part of the external design of the accessory 100 together with the decorative portion 60.

Subsequently, the operation of connecting the clasp 1 in the accessory 100 will be described. FIG. 5 is a diagram showing an example of an operation when the clasp 1 is connected. From the state in which the main body 30, the first plug 10 and the second plug 20 are separated from each other, the user first attaches the first plug 10 to the main body 30 as shown in FIG. 5 (a). On the other hand, it is brought closer in the + D direction. Then, the first ferromagnetic section 10B is attracted to the through hole 43 by the action of the magnetic force of the magnetic force attraction section 40, whereby the first insertion body 10 is guided to the position of the first insertion port 31. ..

Then, as shown in FIG. 5B, the first insertion body 10 is inserted into the insertion hole 33 from the tip portion 10a toward the through hole 43 via the first insertion port 31. The inserted first insertion body 10 advances in the insertion hole 33 in the + D direction and reaches the through hole 43. Then, when the gem 61a comes into contact with the first insertion port 31 of the main body 30, the movement of the first insertion body 10 in the insertion hole 33 in the + D direction stops.

When the gem 61a comes into contact with the first insertion port 31 in this way, the first insertion body 10 is in the following state. That is, the tip portion 10a of the first insertion body 10 is inserted to a position beyond the intermediate portion M of the length L3 in the D direction of the through hole 43 (that is, the position on the + D side of the intermediate portion M). .. Further, the first ferromagnetic section 10B and the connecting section 12 are housed in the insertion hole 33. At this time, the length in the D direction into which the first insertion body 10 and the gem 61a are inserted into the insertion hole 33 is the length L3 in the D direction of the through hole 43 from the first insertion port 31. It is longer than the distance d1 in the D direction to the intermediate portion M, and shorter than the distance d2 in the D direction from the first insertion port 31 to the + D side end 43a of the through hole 43 (see FIG. 5 (c)). ). That is, the tip portion 10a of the first insertion body 10 stays in the through hole 43 and does not penetrate the through hole 43. Further, when the gem 61a comes into contact with the first insertion port 31, the first insertion body 10 is in a state of being pulled in the + D direction with respect to the main body 30 by the magnetic force of the magnetic force attracting portion 40, and is also magnetized. Will be done. The first plug 10 is connected to the main body 30 in such a state. The position of the intermediate portion M is in the middle of the length L3 in the through hole 43, but in the present embodiment, it is also in the middle of the length L2 in the D direction of the insertion hole 33 (see FIG. 3C). ..

Subsequently, as shown in FIG. 5C, the user brings the second plug-in body 20 closer to the main body 30 in the −D direction. Then, the magnetic force of the magnetic force attraction unit 40 and the magnetic force of the magnetized first ferromagnetic unit 10B act on the second ferromagnetic unit 20B. As a result, the second ferromagnetic portion 20B is attracted to the through hole 43, so that the second insertion body 20 is guided to the position of the insertion hole 33.

Further, due to the attractive force of the magnetic force, as shown in FIG. 5D, the second insertion body 20 has a through hole from the tip portion (end portion on the −D side) 20a via the second insertion port 32. It is inserted into the insertion hole 33 toward 43. The inserted second insertion body 20 advances in the insertion hole 33 in the −D direction to reach the through hole 43, and its tip portion 20a abuts on the tip portion 10a of the first insertion body 10 and is attracted. do. The first insertion body 10 adsorbed by the second insertion body 20 moves through the through hole 34 in the −D direction, and the tip portion 10a thereof retracts to the position of the intermediate portion M. At this time, the first ferromagnetic portion 10B stays inside the insertion hole 33, but the connection portion 12 of the first insertion body 10 protrudes to the outside of the insertion hole 33.

In this way, the first insertion body 10 and the second insertion body 20 are connected to each other in a state where the tip portions 10a and 20a are attracted to each other by magnetic force inside the through hole 43. At this time, in the first insertion body 10 and the second insertion body 20, the connecting portions 12 and 12 are in a state of protruding from the insertion holes 33, respectively, and the magnetic force attracting portion 40 is opposed to the magnetic force. It is in a state where it can move relatively in the D direction (see FIG. 6A). At this time, the first ferromagnetic section 10B and the second ferromagnetic section 20B are magnetized by the magnetic force of the magnetic force attraction section 40 and are in a state of being attracted to each other. Therefore, the first plug 10 and the second plug 20 that are connected to each other are not easily detached from the main body 30, respectively, and such a configuration prevents the clasp 1 from being inadvertently disconnected during use. I have to. The user wears the accessory 100 by connecting the clasp 1 in this way.

Subsequently, the operation of disconnecting the clasp 1 in the accessory 100 will be described. FIG. 6 is a diagram showing an example of an operation when the clasp 1 is disconnected. First, the user operates the accessory 100, which has an endless annular shape, so as to pull out the second plug 20 from the main body 30 as shown in FIG. 6 for the clasp 1 connected to the accessory 100. At this time, for example, the user grips the main body 30 with the finger of one hand (for example, the right hand) and the gem 61b with the finger of the other hand (for example, the left hand), and moves the gem 61b from the main body 30 in the + D direction. Apply force to separate them.

Then, as shown in FIG. 6A, the first insertion body 10 and the second insertion body 20 remain adsorbed to each other, and the inside of the insertion hole 33 is + D relative to the main body 30. It moves in the direction, and the gem 61a comes into contact with the main body 30 (first insertion port 31) and stops. At this time, the position of the second plug 20 is farther from the magnetic force attracting portion 40 in the + D direction than the position at the time of connection shown in FIG. 5 (d). That is, the second plug 20 moves away from the magnetic force attracting portion 40 in the + D direction by a distance D3 (see FIG. 6A). Therefore, at this time, the magnetic force acting on the second ferromagnetic portion 20B from the magnetic force attracting portion 40 becomes weaker than that at the time of connection, and the attractive force acting on the second plug 20 becomes lower than at the time of connecting.

Then, the user operates the second insertion body 20 so as to pull it out from the main body 30 in the −D direction. Then, as shown in FIG. 6B, the second insertion body 20 is separated from the insertion hole 33. At this time, as described above, the suction force acting on the second plug 20 is lower than that at the time of connection (in the state of FIG. 5D), so that the user can use the second plug. 20 can be easily pulled out. As a result, the first plug 10 and the second plug 20 are separated from each other, and the disconnection of the clasp 1 is completed. The user thus disconnects the clasp 1 and removes the accessory 100 that he or she was wearing.

As described above, in the state where the connection between the first insertion body 10 and the second insertion body 20 is only released, the main body 30 remains integrally connected to the first insertion body 10. .. Here, when the user pulls out the first insertion body 10 from the main body 30 against the magnetic force, the main body 30 and the first insertion body 10 are separated. At this time, the user grips the main body 30 with the finger of one hand (for example, the left hand) and the gem 61a with the finger of the other hand (for example, the right hand), and the gem 61a is held by the main body 30. It is performed by applying a force so as to be separated in the −D direction. In this way, the user can easily separate the main body 30 from both the first plug 10 and the second plug 20. The operation of disconnecting the clasp 1 described above was to pull out the second plug 20 and the first plug 10 from the main body 30 in this order, but instead of this, the main body 30 is the first. The 1 plug 10 and the 2nd plug 20 may be pulled out in this order. The operation in such a case is the same as the operation described above.

As described above, according to the clasp 1, the main body 30 is different by separating the main body 30 from both the first insertion body 10 and the second insertion body 20 even after being incorporated into the accessory 100. It can be replaced with the one of the design. Therefore, the user can easily change a part of the external design of the accessory 100 and enjoy various designs.

Further, according to the accessory 100 of the second embodiment, the clasp 1 can be easily connected by using a magnetic force. Further, according to the accessory 100, the first insertion body 10 and the second insertion body 20 are attracted to each other inside the through hole 43 and are connected to each other, so that they can be more firmly connected to each other. .. This makes it possible to prevent the accessory 100 from being inadvertently removed during use. Further, according to the accessory 100, in the clasp 1 in the connected state, the second plug 20 acts on the second plug 20 only by moving the second plug 20 in the + D direction relative to the main body 30. The suction power can be weakened. Therefore, by pulling out the second plug 20 from the main body 30 in that state, the clasp 1 can be easily disconnected.

<Third Embodiment>
Subsequently, an example of the clasp 2 according to the third embodiment will be described with reference to the drawings. In the description of the third embodiment, the same or equivalent components as those of the first embodiment described above are designated by the same reference numerals, and the description thereof will be omitted or simplified. FIG. 7 is a side view showing an example of the clasp 2 according to the third embodiment.

The clasp 2 is a fastener used for an annular accessory. As shown in FIG. 7, the clasp 2 includes a first plug 210, a second plug 220, and a main body 30. The first insertion body 210 and the second insertion body 220 are formed so as to be removable from the first insertion port 31 and the second insertion port 32 of the main body 30, respectively. The first plug-in body 210 is inserted in the + D direction and the second plug-in body 220 is inserted in the −D direction with respect to the main body 30, so that the first plug-in body 210 and the second plug-in body 220 are inserted. Are connected to each other by magnetic force (see FIG. 9B). Further, the first insertion body 210 and the second insertion body 220 pull out one of the insertion bodies (for example, the second insertion body 220) from the main body 30 against the magnetic force from the state of being connected to each other. It is possible to separate from each other (disconnect each other). Further, by pulling out the other plug (for example, the first plug 210) from the main body 30 after pulling out one plug (for example, the second plug 220), the main body is pulled out against the magnetic force. It is possible to separate the other plug (eg, the first plug 210) from 30. As described above, the clasp 2 has a configuration in which the first plug-in body 210, the second plug-in body 220, and the main body 30 can be integrally connected and can be separated from each other.

8A and 8B show the first plug-in body 210, where FIG. 8A is a side view, FIG. 8B is a view seen in the −D direction, FIG. 8C is a disassembled vertical end view, and FIG. be. FIG. 8C shows a state in which the member constituting the first ferromagnetic portion 10B and the member constituting the first base portion 210A are disassembled, and the first base portion 210A is shown in a side view and the first ferromagnetic portion 10B is shown. Are shown in the end view. FIG. 8D shows a state in which the decorative portion 260 is attached to the decorative portion 260, which will be described later. As shown in FIG. 8, the first insertion body 210 includes a first base portion 210A and a first ferromagnetic section 10B.

The first base portion 210A is a member for attaching the first ferromagnetic portion 10B to the one end side end portion 260a of the decorative portion 260, which will be described later, and has a tubular portion 211, a connecting portion 212, and a screw shaft 13. There is. In the first base portion 210A, the cylinder portion 211, the connecting portion 212, and the screw shaft 13 are coaxially arranged in this order from the −D side to the + D side.

The tubular portion 211 is formed in a cylindrical shape extending in the −D direction from the surface 212a on the −D side of the connecting portion 212, and has an inner diameter into which the end portion 260a on the −D side of the decorative portion 260 can be inserted. A stopper 70 is provided on the outer peripheral surface 211a of the tubular portion 211. The stopper 70 is provided to regulate the length (insertion length) of the insertion portion of the first insertion body 210 with respect to the insertion hole 33. The stopper 70 is formed in a flange shape protruding outward from the outer peripheral surface 211a of the tubular portion 211, and has a larger outer shape than the insertion hole 33 in the D direction view. Therefore, in the first insertion body 210, the stopper 70 comes into contact with the first insertion port 31 when the insertion length La of the first insertion body 210 is inserted into the insertion hole 33 in the D direction. It is configured as follows.

The insertion length La is the length (distance) in the D direction from the tip end portion (+ D side end portion) 210a to the stopper 70 in the first insertion body 210. Further, the insertion length La is longer than the distance d1 in the D direction from the first insertion port 31 in the main body 30 to the intermediate portion M of the through hole 43, and is from the first insertion port 31 to the through hole 43. It is set shorter than the distance d2 in the D direction to the end 43a on the + D side (see FIG. 10B). Since the insertion length La is set shorter than the distance d2 in this way, the first insertion body 210 does not penetrate the through hole 43. Therefore, when the second plug-in body 220 is brought close to the main body 30 into which the first plug-in body 210 is inserted, an attractive force due to a magnetic force acts on the second plug-in body 220 from the main body 30. The stopper 70 is not limited to the flange shape described above, and may be, for example, a protrusion shape.

The connecting portion 212 is a portion that connects the tubular portion 211 and the screw shaft 13, and has a disk shape with the D direction as the thickness direction. Further, the outer diameter of the connecting portion 212 is set to be the same as the outer diameter of the first ferromagnetic portion 10B. That is, the connecting portion 212 is formed so that the circular outer shape thereof overlaps the outer shape of the first ferromagnetic portion 10B in the D direction view.

The first base portion 210A and the first ferromagnetic portion 10B are fastened and integrated by inserting a screw shaft 13 into a hole 17 and screwing a male screw 13a and a female screw 14. In such a state, the connecting portion 212 and the tubular portion 211 are arranged on the −D side of the −D side end portion 16 of the first ferromagnetic portion 10B.

Returning to the description of FIG. 7, the second plug-in body 220 includes a second base portion 220A and a second ferromagnetic section 20B. The second base 220A has the same configuration as the first 210A described above. Therefore, the second plug-in body 220 has the same configuration as the first plug-in body 210. However, in the second plug-in body 220, the direction in the D direction is opposite to that of the first plug-in body 210. The second plug-in body 220 may have a different configuration from the first plug-in body 210. For example, the second base 220A may have a different configuration from the first 210A, and the second base 220A may have no stopper 70. Further, the second ferromagnetic unit 20B of the second plug-in body 220 may have a configuration different from that of the first ferromagnetic unit 10B.

The connection form of the clasp 2 with the decorative portion 260, and the operation of connecting and disconnecting the clasp 2 will be described later. According to the clasp 2 of the third embodiment as described above, the same effect as that of the clasp 1 of the first embodiment described above is obtained. Further, according to the clasp 2, since the insertion length of the first insertion body 210 is restricted by providing the stopper 70, as will be described later, the first insertion body 210 is inserted. The second plug-in body 220 can be connected to the main body 30 by using a magnetic force.

<Fourth Embodiment>
Subsequently, an example of the accessory 200 according to the fourth embodiment will be described with reference to the drawings. In the description of the fourth embodiment, the same or equivalent components as those of the second embodiment and the third embodiment described above are designated by the same reference numerals, and the description thereof will be omitted or simplified.

9A and 9B are side views of a main part showing an example of the accessory 200, FIG. 9A is an exploded view, FIG. 9B is a state in which the clasp 2 is disconnected, and FIG. 9C is a state in which the clasp 2 is connected. It shows the state, that is, the state at the time of use. The accessory 200 is a ring-shaped accessory, for example, a necklace. As shown in FIG. 9, the accessory 200 includes a clasp 2 and a decorative portion 260. The clasp 2 is used as a fastener for the accessory 200.

As shown in FIG. 9A, the decorative portion 260 has a rope-shaped portion 261. The rope-shaped portion 261 is formed in an elongated rope shape. Further, the rope-shaped portion 261 is a rubber member having a constant diameter from one end to the other end and having a circular cross section. The end portion 261a on one end side (−D side) of the rope-shaped portion 261 has an outer diameter substantially the same as the inner diameter of the tubular portion 211 of the first insertion body 210, and is inserted into the tubular portion 211 (the cylinder portion 211). See FIG. 8 (d)). Similarly, the end portion (not shown) of the other end side (+ D side) of the rope-shaped portion 261 is inserted into the tubular portion 211 of the second insertion body 220. The end portion 261a of the rope-shaped portion 261 is joined to the tubular portion 211 via a bonding material such as an adhesive. A first plug-in body 210 and a second plug-in body 220 are attached to both ends of the decorative portion 260, respectively. The decorative portion 260, the first insertion body 210, and the second insertion body 220 are configured in a series and integrally.

As described above, in the accessory 200, the end portion 261a at one end of the decorative portion 260 is connected to the first plug-in body 210, and the end portion on the other end side of the decorative portion 260 is connected to the second plug-in body 220. There is. Then, as shown in FIG. 9B, when the clasp 2 is connected, the accessory 200 becomes an endless ring. The user uses the accessory 200 in a state where the clasp 2 is connected and the decorative portion 260 is connected in a ring shape in this way. In such a state of use, the main body 30 is a part of the external design of the accessory 200.

Subsequently, the operation of connecting the clasp 2 in the accessory 200 will be described. FIG. 10 is a diagram showing an example of an operation when the clasp 2 of the accessory 200 is connected. From the state in which the main body 30, the first plug 210, and the second plug 220 are separated from each other, the user first sets the first plug 210 as shown in FIG. 10 (a). Bring it close to the inlet 31. Then, the first ferromagnetic section 10B is attracted to the through hole 43 by the action of the magnetic force of the magnetic force attraction section 40, so that the first insertion body 210 is guided to the position of the insertion hole 33.

Then, as shown in FIG. 10B, the first insertion body 210 is inserted into the insertion hole 33 from the tip portion 210a toward the through hole 43 via the first insertion port 31. The inserted first insertion body 10 advances in the insertion hole 33 in the + D direction and reaches the through hole 43. Then, when the stopper 70 comes into contact with the first insertion port 31, the movement of the first insertion body 210 in the insertion hole 33 in the + D direction stops.

When the stopper 70 comes into contact with the first insertion port 31, the first insertion body 210 is in the following state. That is, the first insertion body 210 is in a state in which the insertion length La (see FIG. 8D) is inserted. Further, the tip portion 210a of the first insertion body 210 stops before the end 43a on the + D side of the through hole 43. That is, the tip portion 210a of the first insertion body 210 stays in the through hole 43 and does not penetrate through the through hole 43. Further, the first insertion body 210 is in a state of being pulled in the + D direction with respect to the main body 30 by the magnetic force of the magnetic force attracting portion 40, and is magnetized. The first plug-in body 210 is interconnected with the main body 30 in such a state.

By the way, as described above, the first plug-in body 210 has a stopper 70, but if the first plug-in body is not provided with the stopper 70, the first plug-in body has a length of insertion into the main body 30. Since it is not regulated, it is further inserted into the through hole 43 by the action of magnetic force, and the first ferromagnetic portion 10B is coupled to the main body 30 in a state where the through hole 43 is closed. In such a state, even if the second plug-in body 220 is brought close to the main body 30, the attractive force due to the magnetic force may not sufficiently act on the second plug-in body 220. Therefore, in order to avoid such a state, the first plug-in body 210 is provided with a stopper 70.

Subsequently, the user brings the second insertion body 220 close to the second insertion port 32 as shown in FIG. 10 (c). Then, the magnetic force of the magnetic force attracting portion 40 and the magnetic force of the magnetized first ferromagnetic portion 10B act on the second ferromagnetic portion 20B of the second insertion body 220. The second ferromagnetic portion 20B is attracted to the through hole 43 by such a magnetic force, so that the second insertion body 20 is guided to the position of the second insertion port 32.

Further, as shown in FIG. 10D, the second insertion body 220 is guided to the second insertion port 32 and inserted in the −D direction due to the attractive force of the magnetic force, and enters the insertion hole 33. -Proceed in the D direction to reach the through hole 43. Then, the tip portion (end portion on the −D side) 220a of the second insertion body 220 abuts on the tip portion 210a of the first insertion body 210 and is attracted to the tip portion 210a. The first insertion body 210 adsorbed on the second insertion body 220 moves through the through hole 34 in the −D direction, and the tip portion 210a thereof retracts to the position of the intermediate portion M.

In this way, the first insertion body 210 and the second insertion body 220 are connected to each other in a state where the tip portions 210a and 220a are attracted to each other by magnetic force inside the through hole 43. At this time, in the first insertion body 210 and the second insertion body 220, the tubular portions 211 and 211 and the connection portions 212 and 212 are in a state of protruding from the insertion holes 33, respectively, and the magnetic force is attracted against the magnetic force. It is in a state where it can move in the D direction relative to the unit 40 (see FIG. 11A). At this time, the first ferromagnetic section 10B and the second ferromagnetic section 20B are magnetized by the magnetic force of the magnetic force attraction section 40 and are in a state of being attracted to each other. Therefore, the first plug-in body 210 and the second plug-in body 220 connected to each other are not easily detached from the main body 30, respectively, and such a configuration prevents the clasp 2 from being inadvertently disconnected during use. I have to. The user wears the accessory 200 by connecting the clasp 2 in this way.

Subsequently, the operation of disconnecting the clasp 2 in the accessory 200 will be described. FIG. 11 is a diagram showing an example of an operation when the clasp 2 of the accessory 200 is disconnected. First, the user operates the accessory 200, which has an endless annular shape, so as to pull out the second plug-in body 220 from the main body 30 as shown in FIG. 11 for the clasp 2 connected to the accessory 200. At this time, for example, the user grips the main body 30 with the fingers of one hand (for example, the right hand) and grips the rope-shaped portion 261 on the second insertion body 220 side with the fingers of the other hand (for example, the left hand). , A force is applied so as to separate the second plug-in body 220 from the main body 30 in the + D direction.

Then, as shown in FIG. 11A, the first insertion body 210 and the second insertion body 220 remain adsorbed to each other, and the inside of the insertion hole 33 is in the + D direction relative to the main body 30. The stopper 70 of the first insertion body 210 comes into contact with the main body 30 (first insertion port 31) and stops. At this time, the position of the second plug-in body 220 is farther from the magnetic force attracting portion 40 in the + D direction than the position at the time of connection shown in FIG. 10 (d). That is, at this time, the second plug-in body 220 moves away from the magnetic force attracting portion 40 in the + D direction by a distance D4 (see FIG. 11A). Therefore, at this time, the magnetic force acting on the second ferromagnetic portion 20B from the magnetic force attracting portion 40 becomes weaker than that at the time of connection, and the attractive force acting on the second insertion body 220 becomes lower than at the time of connecting.

Then, the user operates the second plug-in body 220 so as to be pulled out from the main body 30 in the + D direction. Then, as shown in FIG. 11B, the second insertion body 220 is separated from the insertion hole 33. At this time, as described above, the suction force acting on the second plug-in body 220 is lower than that at the time of connection (in the state of FIG. 10 (d)), so that the user can use the second plug-in body. The 220 can be easily pulled out. As a result, the first plug-in body 210 and the second plug-in body 220 are separated from each other, and the disconnection of the clasp 2 is completed. The user disconnects the clasp 2 in this way and removes the accessory 200 that he / she was wearing.

As described above, in the state where the connection between the first plug-in body 210 and the second plug-in body 220 is only released, the main body 30 remains integrally connected to the first plug-in body 210. .. Here, when the user pulls out the first insertion body 210 from the main body 30 against the magnetic force, the main body 30 and the first insertion body 210 are separated. At this time, the user grips the main body 30 with the fingers of one hand (for example, the left hand) and the rope-shaped portion on the first insertion body 210 side with the fingers of the other hand (for example, the right hand). This is done by grasping the 261 and applying a force so as to separate the first insertion body 210 from the main body 30 in the + D direction. In this way, the main body 30 can be easily separated from both the first insertion body 210 and the second insertion body 220. This makes it possible to replace the main body 30 with one having a different design. The above-mentioned disconnection was to pull out the second plug 220 and the first plug 210 from the main body 30 in this order, but instead, the second base 220A includes a stopper 70. If it is configured, the first plug-in body 210 and the second plug-in body 220 may be pulled out from the main body 30 in this order. The operation in such a case is the same as the above description.

According to the accessory 200 of the fourth embodiment, the same effect as that of the accessory 100 of the second embodiment described above is obtained.

Although the embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the above-mentioned description. Various changes can be made to the above embodiments without departing from the gist of the present invention. For example, some of the requirements described in each of the above embodiments can be omitted or combined as appropriate.

Further, in the above-described embodiment, the magnetic attraction unit 40 is a magnet, and both the first insertion bodies 10, 210 and the second insertion bodies 20, 220 have a ferromagnetic material, but the magnetic attraction is attracted. The configuration is not limited to the above, as long as the unit 40 attracts the first insertion body 10 and the like and the second insertion body 20 and the like by magnetic force. That is, the configuration is not limited to the above configuration as long as the first plug 10 and the like and the second plug 20 and the like are connected to each other by magnetic force via the main body 30. Therefore, for example, one or both of the first insertion body 10 and the like and the second insertion body 20 and the like are replaced with a structure having a magnet, and the magnetic attraction unit 40 is a structure of a ferromagnetic material that attracts the magnet. May be good. In such a case, the first plug may be configured to include a magnet having the same shape as the first ferromagnetic part 10B instead of the first ferromagnetic part 10B, and the second plug may have a second ferromagnetic part 20B. Alternatively, a magnet having the same shape as the second ferromagnetic unit 20B may be provided.

Further, in the clasps 1 and 2 of the above-described embodiment, the first plug 10 and the like and the second plug 20 and the like are inserted into the main body 30 in opposite directions. It is not limited, and may be configured to be inserted in different directions that are not parallel to each other. In such a case, the insertion hole of the main body 30 is formed along the direction in which the first insertion body and the second insertion body are inserted.

Further, the mutual connection between the clasps 1 and 2 described above and the decorative portions 60 and 260 is not limited to the above mode, and various changes can be made. For example, the clasp 1 may have a ring-shaped connecting ring portion instead of the insertion portion 11, or may be connected to the decorative portion 60 with the connecting thread 62 attached to the connecting ring portion. Further, the clasp 2 may have a ring-shaped connecting ring portion instead of the rope-shaped portion 261 tubular portion 211, and may be connected to the rope-shaped portion 261 via such a connecting ring portion. In such a case, the end portion 261a of the rope-shaped portion 261 is formed in a shape that can be connected to the connecting ring portion.

Further, in the above-described embodiment, the accessories 100 and 200 are accessories used in a state of being connected in an endless ring, and the clasps 1 and 2 are fasteners for connecting the decorative portions 60 and 260 in an endless ring. However, it is not limited to such a configuration. For example, the clasp 1 or the like may have a configuration in which a part of the decorative portion 60 or the like is connected in a ring shape, or a configuration in which a plurality of decorative portions 60 or the like are connected in a series. Further, the accessory 100 or the like may be configured such that a part thereof is connected in a ring shape via the clasp 1 or the like, or a configuration in which a plurality of decorative portions 60 or the like are connected. Further, the use of the clasp 1 or the like is not limited to the fastener of the accessory, and may be applied to, for example, a connecting means for connecting the main body of the mobile terminal and the strap.

Further, in the above-described embodiment, the first insertion bodies 10, 210 and the second insertion bodies 20, 220 have their respective tip portions 10a, 20a, 210a, 220a in contact with each other in the through hole 43. It was linked, but is not limited to such an embodiment. For example, the first insertion body 10 and the like and the second insertion body 20 and the like are connected to each other in a state where either or both of them have not reached the through hole 43 (that is, at a position in front of the through hole 43).
