[Action]

 In the accessory mounting mechanism configured as described above, the first member attached to both ends of the connecting member is provided with the pair of taper wall portions, and the second member is provided with the taper portions that are aligned with the taper wall portions. By tapering the wall portion and the tapered portion, the first member and the second member are connected to each other to form a closed annular body together with the connecting member. The closed-chain ring can be worn like a well-known necklace or bracelet. For example, if a necklace chain or the like is used as a connecting member, the accessory mounting mechanism itself becomes the accessory. Also, a pendant top or the like can be attached to the connecting member.

Since the accessory can be mounted only by connecting the first member and the second member by tapering, the accessory can be easily mounted without requiring special work such as operation of fine parts. Further, the distance between the tapered wall portions becomes narrower as the distance from the connecting portion with the connecting member decreases, and the width of the tapered portion becomes narrower on the connecting portion side with the connecting member. Even if is applied, this force will act in a direction to bite the taper alignment. Therefore, even if such an external force is applied, the joint between the first member and the second member is not released, and the necklace chain or the like does not fall off the body of the user.

Further, when the tapered wall portion is provided with the protruding portion that projects toward the opposite tapered wall portion, the first member and the second member are separated from each other in the above-mentioned joined state. Even when an external force acts in the direction of separating, the protruding portion prevents the separation of the two, so the first member and the second member are separated and separated from each other by such an external force, and the necklace chain or the like is worn on the user's body. Never fall out of.

Here, when the protruding portion is formed by bending the tapered wall portion as described in claim 3, the processing is easy. Further, as described in claim 4, the first member is provided with an elastic portion which has a spherical convex portion and is elastically deformed in a direction along the wall surface of the tapered wall portion, and the second member is provided with the convex portion of the convex portion. By providing a hole having an inner diameter corresponding to the outer diameter and engaging the protrusion and the hole when the taper is made, the connection between the first member and the second member can be held more reliably.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. (Embodiment 1) As shown in FIG. 1, an accessory mounting mechanism 10 of the present embodiment includes a neckless chain 12 as a connecting member and a neckless chain 12 connected to an end of the necklace chain 12 through a connecting hole 14a. The second member 16 is connected to the first member 14 through the connecting hole 16a, and the accessory wearing mechanism 10 itself has a necklace function as the accessory.

The first member 14 is made of a gold alloy, and a pair of tapered wall portions 18 a and 18 b are provided upright on both sides of the plate-shaped base portion 15 substantially perpendicular to the inner surface 15 a of the base portion 15. . The distance between the tapered wall portions 18a and 18b is wide on the side of the connecting hole 14a and becomes narrower as the distance from the connecting hole 14a increases. Further, the upper ends of the tapered wall portions 18a and 18b are bent so as to project toward the opposite tapered wall portions 18a and 18b, and projecting portions 19a and 19b are formed.

Further, a U-shaped through hole 15b is formed in the central portion of the base portion 15, and the elastic portion 20 is formed as a substantially rectangular portion surrounded by the through hole 15b. The elastic portion 20 has one end portion 20a fixed and the other three sides being free ends, and is elastically deformable along the arrow P and Q directions with the end portion 20a as a fulcrum. The vicinity of the end of the elastic portion 20 on the arrow L side is pressed so as to project to the inner surface 15a side of the base portion 15 to form a spherical convex portion 22.

On the other hand, the second member 16 is made of a gold alloy and has a strip-shaped arm portion 24a provided with a connection hole 16a and a head portion 24b connected to the arm portion 24a on the side remote from the connection hole 16a. It is composed of The head portion 24b has a substantially trapezoidal shape in which the width on the side of the arm portion 24a is narrow and the width thereof becomes wider as the distance from the arm portion 24a increases. The tapered portions 26a and 26b are aligned with the space. Further, as shown in FIG. 1B, the plate thickness of the second member 16 is set to be slightly thinner than the distance S between the base portion 15 of the first member 14 and the protruding portions 19a and 19b. .

Further, a hole portion 28 penetrating the head portion 24b is formed near the center of the head portion 24b from the lower surface 30a to the upper surface 30b side. The inner diameter of the hole 28 is substantially the same as the outer diameter of the convex portion 22 of the first member 14, and as shown in FIG. 1C, the convex portion 22 is inserted into the hole 28 so that they are engaged with each other. It is possible.

Although not shown, the first member 14 side and the second member 16 side of the necklace chain 12 are continuous. A well-known pendant top (not shown) or the like can be attached to the necklace chain 12. When mounting the accessory mounting mechanism 10 around the neck, for example, the necklace chain 12 is rotated around the neck in the same manner as in the conventional case with the first member 14 and the second member 16 separated from each other. The inner surface 15a of the first member 14 and the lower surface 30a of the second member 16 are brought into contact with each other. At this time, the relative positions of the first member 14 and the second member 16 are, for example, the positional relationship shown by the two-dot chain line for the second member 16 in FIG. Subsequently, the first member 14 is moved relative to the arrow R direction, or the second member 16 is moved relative to the arrow L direction. During this relative movement, the second member 16 is restricted from moving toward the upper surface 30b by the protruding portions 19a and 19b of the tapered wall portions 18a and 18b, so that the lower surface 30a of the second member 16 has a convex portion of the elastic portion 20. The portion 22 is pressed to elastically deform the elastic portion 20 in the arrow P direction. Therefore, the second member 16 is relatively moved while being sandwiched by the projecting portions 19a and 19b and the elastic portion 20. When this relative movement is continued and the hole portion 28 of the head portion 24b reaches the convex portion 22 of the elastic portion 20, the elastic portion 20 is released from the above-mentioned pressing and is restored and deformed in the direction of the arrow Q, and at the same time, the convex portion is 22 and the hole 28 are engaged with each other. At the same time, the tapered portions 26a and 26b of the head portion 24b and the tapered wall portions 18a and 18b of the first member 14 are brought into a tapered state.

In this way, the first member 14 and the second member 16 are connected by tapering to form a closed annular body together with the necklace chain 12. Further, since the first member 14 and the second member 16 are restricted from varying relative positions in the directions of the arrows R and L by the engagement of the protrusion 22 and the hole 28, for example, the second member 16 is The relative movement in the direction of arrow R is prevented from canceling the taper-matched state.

To remove the wearing accessory mounting mechanism 10, for example, the first member 14 and the second member 16 are respectively held by fingers, and the first member 14 is moved in the direction of the arrow L and the second member 16 is moved. Relative movement is made in the direction of arrow R to cancel the taper alignment between the two. At this time, the elastic portion 20 is pressed by the lower surface 30a of the second member 16 and elastically deforms in the arrow P direction, and the engagement between the convex portion 22 and the hole portion 28 is released.

As described above, in the accessory mounting mechanism 10, the first member 14 and the second member 16 can be mounted and dismounted by simply moving them in parallel. For this reason, no special work such as operation of fine parts is required when mounting or removing the wearing mechanism 10 for the accessory, and the mounting and removing can be easily performed. However, for example, the necklace chain 12 may be obstructed during use. May get caught in. In such a case, the external force acting on the neckless chain 12 pulls the second member 16 in the arrow L direction shown in FIG. 1 and pulls the first member 14 in the arrow R direction. That is, such an external force acts in a direction in which the taper alignment between the first member 14 and the second member 16 is further depressed, and the connection between the two is further strengthened. Therefore, even if such an external force is applied, the joined state between the first member 14 and the second member 16 is not released, and the neckless chain 12 does not drop out from the user's body.

Moreover, even when an external force such as peeling the second member 16 from the first member 54 is applied at the time of mounting, the protrusions 19a and 19b provided on the tapered wall portions 18a and 18b have the first members. Since the peeling between 14 and the second member 16 is prevented, the accessory (necklace chain 12) can be more reliably held on the body.

Although the attachment mechanism for accessory of the present invention has been described above according to the embodiments, the present invention is not limited to these embodiments and can be variously implemented without departing from the scope of the present invention. . For example, although the first member and the second member are made of a gold alloy in the embodiment, various materials such as steel, stainless steel and other metals and plastics can be used in addition to the gold alloy, and the surface is plated with nickel or the like. Good. Further, the first member and the second member may be made of different materials.

The distance S from the inner surface of the first member to the protruding portion needs to be slightly larger than the plate thickness of the head of the second member, but this distance S is the deformability of the elastic portion and the convex portion. It is desirable to make a decision taking into consideration the height of

[0023]

[Effect of device]

 As described above, the accessory mounting mechanism of the present invention does not require complicated operations for mounting and dismounting, and these operations are extremely simple. Further, even if an external force such as pulling the necklace chain is applied, the joining state of the accessory mounting mechanism is prevented from being released, and the inconvenience of the joining being released during use is eliminated.

Further, as described in claim 2, when the tapered wall portion is provided with the protrusion protruding toward the opposite tapered wall portion, the first member and the second member are separated from each other in the above-mentioned joined state. Even when an external force acts in the direction of separating, the protruding portion prevents the separation of the two, so the first member and the second member are separated and separated from each other by such an external force, and the necklace chain or the like is worn on the user's body. Never fall out of.

Here, when the protruding portion is formed by bending the tapered wall portion as described in claim 3, the processing is easy. Further, as described in claim 4, the first member is provided with an elastic portion which has a spherical convex portion and is elastically deformed in a direction along the wall surface of the tapered wall portion, and the second member is provided with the convex portion of the convex portion. By providing a hole having an inner diameter corresponding to the outer diameter and engaging the protrusion and the hole when the taper is made, the connection between the first member and the second member can be held more reliably.
