Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is an explanatory view showing one embodiment of the accessory attachment device of the present invention. FIG. 2 is a development explanatory view of the inner surface of the insertion recess provided in the receptor of the embodiment shown in FIG. FIG. 3 illustrates, in another aspect,
FIG. 3 is a development explanatory view of the surface of the insertion recess similar to FIG. 2. FIG.
FIG. 6 is an exploded view showing still another embodiment of the accessory attachment device of the present invention, in which a receptor is a combination type. FIG.
FIG. 5A is a plan view and FIG. 5B is a developed view of a core used in the embodiment shown in FIG. 4. FIG. 6 is an explanatory diagram showing a process of obtaining a connection state using the embodiment shown in FIG. As shown in FIG. 1, the coupling device according to the present invention comprises a receiver 1, an insertion recess 3 provided therein, and an insertion body 2 inserted therein.
It is basically composed of The bottom of the insertion recess 3 is a permanent magnet 4 (see FIG. 4, not shown in FIG. 1).

[0006] When the receiver 1 and the insert 2 are connected to each other, the overall shape is appropriate as a part of the accessory. In the embodiment shown in FIG. 1, it has a spheroidal shape as a whole. This overall shape is optional,
It can have any suitable shape, for example, a columnar shape, a prismatic shape, a butterfly shape, and the like. One end of each of the receiver 1 and the insert 2 is provided with a ring 19, 20 for stopping a chain or the like as a decorative accessory.
Are formed. In the embodiment shown in FIG. 1, a ring is formed by a concave portion having a gentle curved surface near each end of the spheroid. The concave portion having the gentle curved surface is shaped to be suitable for picking up with a fingertip and discriminating and sensing the orientation of the receptor / insert. The engagement ring is, for example, a plate-shaped body at one end of the receiver / insert, formed on the plate-shaped body, or separately attached with a wire like a wire, and appropriately modified. That is fine.

The receiver 1 and the insert 2 may be manufactured by precision casting, for example, lost wax or the like, or machined from a block-shaped material such as solid wood or laminated wood into a required shape. It may be something. It may be formed by combining and combining unit parts. The surfaces of the receiver 1 and the insert 2 may have been subjected to a surface treatment such as plating. In addition, decorative uneven patterns, decorative lines,
It is also preferable that coloring or the like is applied to the surface. Receptor 1
As shown in FIG. 2 as a development explanatory view of the insertion recess 3, an introduction groove 5 is provided on the surface of the insertion recess 3 from the opening side to an appropriate depth in the axial direction of the insertion recess 3. At the bottom of the groove 5, a retaining groove 6 is provided continuously in a plane orthogonal to the axis of the insertion concave portion 3. In the vicinity of the introduction groove 5 of the retaining groove 6, it is desirable that a return preventing convex portion 8 is formed.

The bottom surface of the insertion recess 3 is a permanent magnet 4. The permanent magnet 4 is attached to the extension position of the insertion recess 3 by bonding or the like.
It is fixed by an appropriate means. The other end of the insert 2 opposite the engagement ring 20 is an insertion end 9 that fits into the insertion recess 3 formed in the receiver 1. On the side of the insertion end 9, a projection 7 is provided which engages with the introduction groove 5 and the retaining groove 6 formed on the inner surface of the insertion recess 3 of the receiver 1.
There is no limitation on the installation position of the projection 7 as long as it is on the side of the insertion end 9, but it is preferable that the projection 7 is provided not at the tip of the side of the insertion end 9 but slightly away from the tip.

The projection 7 is preferably in the form of a small column. However, as long as the projection 7 can be inserted into the introduction groove 5 for receiving the projection, the projection 7 may be in the shape of a prism such as a triangular prism, a quadrangular prism, a pentagonal prism, or an elliptical column. There may be. The height of the protrusion 7 is not particularly limited as long as it can be accommodated in the introduction groove 5 and the retaining groove 6. By gripping the engagement rings 19 and 20 between the receptor 1 and the insert 2 with a finger, the relative orientation of the receptor 1 and the insert 2 and furthermore the relative orientation of the protrusion 7 and the introduction groove 5 can be sensed as such. However, if the position of the protrusion 7 is provided slightly away from the tip of the insertion end 9 as described above, the portion from the tip of the insertion end 9 to the position where the protrusion 7 is provided first. It becomes easy to enter the insertion recess 3 to determine the corresponding position between the receptor 1 and the insert 2 and then determine the corresponding position between the projection 7 and the introduction groove 5.

The diameter of the vicinity of the insertion opening of the insertion recess 3 is gradually increased outward, or the width of the introduction groove 5 near the introduction start end is gradually increased toward the introduction start end. This can be convenient for guiding the insertion end 9 and the projection 7. When the insertion body 2 is attracted to the permanent magnet 4 provided at the bottom of the insertion recess 3, the protrusion 7 is guided along the introduction groove 5, and the insertion body 2 enters the insertion recess 3, the insertion body 2 is removed from the insertion recess 3. Required angle around the axis of rotation,
For example, it is rotated by 45 to 135 °, preferably about 90 °. When the insert 2 is rotated, the projection 7 moves from the introduction groove 5 along the retaining groove 6 in a plane perpendicular to the axis of the insertion recess 3, and the coupling state is completed and the locked state is established.

When the coupling state between the receiver 1 and the insert 2 is completed and the locked state is established, as is apparent from FIG. 2, the innermost part of the retaining groove 6 is located in the insertion recess 3 of the receiver 1. Since there is no groove = passage that is linearly connected to the exit direction,
Even if an external force acts in a direction in which the receiver 1 and the insert 2 are separated from each other, there is no possibility that the two will be separated from each other. If a small anti-return protrusion 8 (FIG. 2) is formed at an appropriate position such as near the end of the retaining groove 6 on the introduction groove side, the protrusion 7 comes into contact with the anti-return protrusion 8 so that the insert 2 Can be sensed by the finger that the position of the lock is in the locked state.
The projection 7 rotates toward the introduction groove 5 due to a rotational force or other cause based on the twist of the chain or the like connected and engaged with
It also has the effect of preventing unexpected rotation of the insert 2 from coming off the receiver 1.

In order to release the locked state between the receiver 1 and the insert 2, the locking rings 19 and 20 are pinched and rotated in a direction opposite to the direction in which the locking state is first brought to the locked state, and a force is applied in a direction in which they are separated. You can put It is preferable that the engagement rings 19 and 20 be oriented in the same direction when the insert 2 is rotated so as to reach the coupled state. The orientation of the engagement rings 19 and 20 is set at a set position and angle between the surface including the center line of the hole of the engagement ring 20 and the axis of the projection 7 so that the relative positions and angles can be arbitrarily determined. I do. Normally, it is desirable that this angular relationship be vertical.

In the embodiment shown in FIGS. 1 and 2, the introduction groove 5 is provided in parallel with the axis of the insertion recess 3, the rotation for reaching the locked state is about 90 °, and the hole of the engagement ring 19 is formed. Since the introduction groove 5 is present in the plane including the center line, the plane including the center line of the hole of the engagement ring 20 and the axis of the projection 7 are in a perpendicular relationship. Since the positional (orientation) relationship between the surface including the center line of the hole of the engagement ring 19 and the introduction groove 5 can be set arbitrarily, the position of the surface including the center line of the hole of the engagement ring 20 and the axis of the projection 7 are adjusted accordingly. Reconcile relationships. Unlike the embodiment shown in FIGS. 1 and 2, as shown in FIG. 3, the introduction groove 5 is provided at an angle to the axis of the insertion recess 3, and an appropriate angle, for example, 90 °, while the protrusion 7 advances along the introduction groove 5. When the retaining groove 6 is provided at an acute angle to the introduction groove 5, the surface including the center line of the hole of the engagement ring 20 and the axis of the projection 7 are coplanar. It can be appropriately modified.

Further, in the embodiment shown in FIG.
Is linearly provided in a plane orthogonal to the axis of the insertion recess 3, but is not limited to this. For example, by bending the insertion end 9 slightly and downward at the innermost portion so that the tip of the insertion end 9 contacts the surface of the permanent magnet 4 in the locked state, the insertion end 9 or the permanent Wear of the magnet 4 can be avoided. At least the outer portions of the receiver 1 and the insert 2 are preferably made of a non-magnetic material, and can be made of, for example, a noble metal, aluminum, brass, stainless steel, Ti, or a plastic material. Further, it is necessary to arrange a magnetic material such as iron near the insertion end 9 of the receptor 2 or near the tip of the insertion end 9.

The permanent magnet 4 fixed by adhesion or the like so as to form the bottom of the insertion concave portion 3 of the receiver 1 may be any commonly used permanent magnet. However, a rare earth magnet having high holding power is preferable. Another embodiment of the present invention in which the receptor is a combination type will be described with reference to FIGS. 4 and 5. In FIG. 4, the receiver 1 is basically composed of a pipe 10 having an inward flange 11, a core 14, a permanent magnet 4, and a knob 18. An inward flange 11 is formed at one end of the pipe 10, and the other end has a shape obtained by cutting the pipe perpendicular to the axis. From the other end, the core 14, the permanent magnet 4, and the knob 18 are inserted to assemble the receiver. At least the knob 18 is fixed to the pipe 10 by a suitable joining means such as a screwing mechanism, bonding with an adhesive, caulking, soldering, ultrasonic welding, resistance welding, or the like.

The permanent magnet 4 and the core 14 are provided with a knob 18
As in the case of fixing the pipe, the pipe may be fixed to the pipe 10 or may be simply held between the flange 11 of the pipe 10 and the knob 18 fixed to the pipe 10. The overhang length of the flange 11 corresponds to the thickness of the core 14. A part of the flange 11 has a cut portion 12 which becomes a part of the introduction groove 5 and a tongue portion 1 of a core 14.
The cutting portion 13 with which the engaging portion 6 engages is cut off. As shown in FIG. 5B, the core 14 has a tongue 16 that engages with the cutout 13 of the pipe 10, the introduction groove 5 and the retaining groove 6 in a plate having a required thickness. It is obtained by forming a notch 15 to be formed, and bending and forming the cutout so as to have an outer diameter that matches the inner diameter of the pipe 10 (see FIG. 5A).

When the core 14 is formed, the end faces which are both ends in the developed view shown in FIG. 5 (b) may be in contact with both ends, but as shown in FIG. 1
7 is formed during the assembly.
4 is preferable because it can be elastically deformed with a small diameter. Tongue 16 of core 14 and flange 11 of pipe 10
Is engaged with the cut-out portion 13 provided in the pipe 1, the core 14 in the receiver 1 is reliably prevented from rotating in the pipe 10. When the core 14 is fixed to the pipe 10, the tongue 16 and the cut-out 13
Is not always necessary.

The permanent magnet 4 is preferably in the form of a disk having an outer diameter that matches the inner diameter of the pipe 10, but is not necessarily limited to this shape as long as it is appropriately fixed or fixed in the pipe 10. . Knob 18 is for pipe 1
It has an outer diameter that matches the inner diameter of 0, one end is substantially planar, and the other end is provided with an engagement ring 19. In the embodiment shown in FIG. 4, the engagement ring 19 has a shape in which a small hole is formed in a flat plate whose outer edge is a half-elliptical shape, and is formed to protrude as a part of the knob 18. The flat body is joined to the knob 18 as a separate body.
It may be fixed.

In the receiver 1 of the embodiment shown in FIG. 4, the core 14 is housed by fitting the tongue 16 of the core 14 into the cutout 13 of the flange 11 in the pipe 10 in the order shown in FIG. Next, the permanent magnet 4 is inserted. Then, the knob 18 is inserted into the pipe 10 and fixed to the pipe 10. In the embodiment shown in FIG.
The plane including the center line of the hole and the introduction groove 5 are in the same plane. An insertion recess is formed between the inner periphery of the flange 11 of the pipe 10 and the inner periphery of the core 14, and the introduction groove and the retaining groove are formed by the lower surface of the flange 11 and the notch 15 of the core 14 and the gap 17 between the cores 14. A groove is formed. Core 14
The small bulge provided in the notch 15 is the return preventing convex 8.

The shape of the notch 14 of the core 14 is shown in FIG.
Not limited to those shown in the above, unlike the case where the retaining groove is formed in cooperation with the flange 11 of the pipe 10, an appropriate modification such as a mode in which the groove is completely formed in the core portion is adopted. It is possible. The insert 2 inserted into the receiver 1 has an engagement ring 20 at one end and an insertion end 9 at the other end with a protrusion 7 on the side. In the embodiment shown in FIG. 4, a ring-shaped body having the same shape as the ring 19 at the one end of a disk-shaped body having the same diameter as the outer diameter of the pipe 10 and having a small hole formed in a flat elliptical outer edge. 2

In the embodiment shown in FIG. 6 in which the surface including the center line of the hole of the engagement ring 19 and the introduction groove 5 are in the same plane, the engagement between the surface including the center line of the hole of the engagement ring 19 of the receptor 1 and the insert 2 is illustrated. The insertion body 2 is inserted into the receiver 1 so that the planes including the center line of the hole of the ring 20 are perpendicular to each other, and then rotated by 90 ° to be in the locked state.

Therefore, also in this embodiment, similarly to the embodiment shown in FIG. 1, the surface including the center line of the hole of the engagement ring 20 and the axis of the projection 7 are in a perpendicular relationship. The positional (angular) relationship between the surface including the center line of the hole of the engagement ring 20 and the axis of the projection 7 is not limited to this, and the surfaces including the center lines of the holes of the engagement rings 19 and 20 are coupled in the same direction. May be started, and the locked state may be set when the directions are different, for example, orthogonal. Same orientation
It is needless to say that the relationship is not limited to the orthogonal, and an arbitrary relationship is also possible. Further, it is the same as the embodiment shown in FIG. 1 that the introduction groove can be formed to be inclined, the coupling can be started in the same direction, and the locked state can be set in the same direction.
