As shown in FIGS. 4 and 5, the movable member 30 includes the engaging portion 31 and the operation portion 32 as described above, and the first through hole for allowing the pin 50 to pass through the movable member 30. 33, a second through hole 34 for allowing the insertion member 20 (for example, particularly the small diameter portion 23) to pass through the movable member 30, and a spring holding portion for holding a part of the coil spring 40 in an extrapolated state. 35 and an urging receiving portion 36 that receives an urging force from the coil spring 40.

  Here, the movable member 30 is configured in a pin shape (round bar shape), and its diameter changes, for example, in three stages. That is, the movable member 30 includes, for example, a large-diameter portion 301, a medium-diameter portion 302, and a small-diameter portion 303 in this arrangement order as shown in FIG.

  The operation portion 32 is configured by one end portion (for example, the large diameter portion 301) of the movable member 30.

  Further, the first through-hole 33 that penetrates the pin 50 is formed in a state of penetrating the movable member 30 in a direction orthogonal to the longitudinal direction. The first through hole 33 allows the movable member 30 to move in the operating direction and the engaging direction of the engaging portion 31 (the direction of arrow E and F in FIG. 4) which is the opposite direction even when the pin 50 is penetrated. In addition, the diameter of the pin 50 (the main body cylinder 51) is formed to be sufficiently larger than the diameter of the pin 50 (the main body cylinder 51). The dimension is set to be slightly larger than that.

  Further, the second through hole 34 that penetrates the insertion member 20 is also formed so as to penetrate the movable member 30 in a direction orthogonal to the longitudinal direction thereof. In addition, the penetration direction of the 1st and 2nd through-holes 33 and 34 is set to the mutually parallel direction, for example. Therefore, the insertion member 20 and the pin 50 penetrate the movable member 30 in a state parallel to each other and are attached to the decorative member 210. Further, the second through-hole 34 is formed in the engaging direction of the engaging portion 31 (the arrow E direction and the F direction in FIG. 4) in which the movable member 30 is in the operation direction and the opposite direction even when the insertion member 20 is penetrated. In this direction, the insertion member 20 (the small diameter portion 23) is formed to be sufficiently larger than the diameter thereof, but in the direction from the front to the back of the paper surface of FIG. The diameter is set to be slightly larger than the diameter of the small diameter portion 23).

  Further, the engaging portion 31 is formed of, for example, a protruding portion, and is formed to stand from the inner peripheral surface of the second through hole 34 toward the center side of the second through hole 34. More specifically, the engaging portion 31 is disposed on the inner peripheral surface of the second through-hole 34, for example, on the spring holding portion 35 side. The engaging portion 31 is formed with an inclined surface 31a (FIG. 4) facing the insertion hole 13 side. The inclined surface 31a suitably guides the distal end portion 22 of the insertion member 20 into the second through hole 34.

  The first through hole 33 is provided, for example, in a portion from the large diameter portion 301 to the medium diameter portion 302, and the second through hole 34 is provided, for example, in the medium diameter portion 302.

  Moreover, the spring holding part 35 is comprised by the small diameter part 303, for example. The diameter of the spring holding portion 35 (that is, the diameter of the small diameter portion 303, for example) is set to be substantially the same as the inner diameter of the coil spring 40.

  Further, the urging receiving portion 36 that receives the urging force from the coil spring 40 includes, for example, a step portion at the boundary between the small diameter portion 303 and the medium diameter portion 302.

<Pin>
In the case of the present embodiment, the pin 50 is, for example, a spring bar as shown in FIG.

  That is, the pin 50 is compressed into the cylindrical main body cylinder 51, the projecting member 52 provided on the main body cylinder 51 so as to be able to protrude from the openings at both ends of the main body cylinder 51, and the main body cylinder 51. And a compression type coil spring (biasing means) 53 arranged in a state.

  Among these members, the protruding member 52 is disposed in the main body cylinder 51 and slides along the inner peripheral surface of the main body cylinder 51, and is configured to have a smaller diameter than the sliding section 52a and outside the main body cylinder 51. And an expansion / contraction portion 52b that can protrude or enter the main body cylinder 51.

  Further, both end portions of the main body cylinder 51 are bent inward with the coil spring 53 and the pair of projecting members 52 disposed in the main body cylinder 51, and the opening areas of the both end portions are equal to each other. Although it is larger than the diameter of the expansion / contraction part 52b, it is narrowed to an area smaller than the diameter of the sliding part 52a. Thereby, the pair of protruding members 52 and the coil spring 53 are prevented from falling off from the main body cylinder 51.

  In such a pin 50, when the expansion / contraction part 52b of the protruding member 52 is pushed in the direction of arrow A in FIG. 6 (in the direction of arrow B in the case of the right-side protruding member 52), the expansion / contraction part 52b of the pushed protruding member 52 is pressed. However, it enters the main body cylinder 51 against the urging of the coil spring 53, and the pin 50 is contracted in appearance. At this time, the sliding portion 52 a slides along the inner peripheral surface of the main body cylinder 51. Further, when the pressing force on the projecting member 52 is released, the expansion / contraction portion 52b of the projecting member 52 again projects out of the main body cylinder 51 in accordance with the urging of the coil spring 53, and the pin 50 extends in appearance.

<Guide tube>
As shown in FIGS. 4 and 5, the guide tube 60 includes a first through hole 63 for allowing the pin 50 to pass through the guide tube 60 and an insertion member 20 (for example, In particular, a second through hole 64 for penetrating the small diameter portion 23) and an insertion hole 69 for inserting the movable member 30 therein are provided.

  Here, the guide cylinder 60 is configured, for example, in a cylindrical shape (for example, a cylindrical shape) having both ends opened.

  An insertion hole 69 is formed by the inner peripheral portion of the guide tube 60.

  Further, the first through hole 63 through which the pin 50 passes is formed in a state of penetrating the guide tube 60 in a direction orthogonal to the longitudinal direction. The first through-hole 63 is set to a size slightly larger than the diameter of the pin 50 (the main body cylinder 51).

  The second through hole 64 that penetrates the insertion member 20 is also formed in a state of penetrating the guide tube 60 in a direction orthogonal to the longitudinal direction. In addition, the penetration direction of the 1st and 2nd through-holes 63 and 64 is set to the mutually parallel direction, for example. Therefore, the insertion member 20 and the pin 50 pass through the guide tube 60 in a state parallel to each other and are attached to the decorative member 210. Moreover, the 2nd through-hole 64 is set to the dimension slightly larger than the diameter of the insertion member 20 (the small diameter part 23).

  Note that the outer diameter of the guide cylinder 60 changes in, for example, two stages. That is, the guide tube 60 includes, for example, a large diameter portion 601 and a small diameter portion 602 adjacent to each other as shown in FIG.

  Among these, the large diameter portion 601 is provided with a first through hole 63 and a second through hole 64.

  A buffer ring 70 is extrapolated to the small diameter portion 602.

<Decorative material>
As shown in FIGS. 4 and 5, the decorative member 210 is configured, for example, in an elliptical columnar casing shape.

  Similarly to the decorative member 10 in the case of the first embodiment, the decorative member 210 is made of, for example, a material different from each component of the accessory fastener constituting jig 200.

  The decorative member 210 is provided with a disposition hole 211 serving as a disposition region for the movable member 30, the guide tube 60, the coil spring 40, and the pin 50.

  As will be described later, the movable member 30, the guide cylinder 60, the coil spring 40, and the pin 50 are inserted into the arrangement hole 211 and arranged in the arrangement hole 211.

  In addition, a cylindrical wall portion 212 that constitutes the arrangement hole 211 is formed integrally with the decoration member 210 inside the decoration member 210.

  Furthermore, the decoration member 210 is formed with an insertion hole 213 into which the insertion member 20 is inserted. The insertion hole 213 is formed such that the insertion direction of the insertion member 20 is a crossing direction, more specifically, an orthogonal direction with respect to the insertion direction of the movable member 30 into the arrangement hole 211. More specifically, the insertion direction of the insertion member 20 and the insertion direction of the movable member 30 into the arrangement hole 211 are included in the same plane.

  Further, a through hole 212a is formed in the wall portion 212, and the insertion member 20 inserted through the insertion hole 213 passes through the through hole 212a. In addition, this through-hole 212a is a mortar-shaped part that expands as it approaches the insertion hole 213 (is narrowed as it moves away from the insertion hole 213), and the tip 22 of the insertion member 20 is moved to the center position of the through-hole 212a. Guide it favorably.

  In the interior space of the decorative member 210, the portion closer to the insertion hole 213 than the wall-shaped portion 212 and the portion farther from the insertion hole 213 than the wall-shaped portion 212 are spaces into which the insertion member 20 is inserted. The parts 218 and 219 are configured.

  Further, the wall-like portion 212 is formed with a pair of holes 214 and 215 for positioning the pin 50. More specifically, the positioning holes 214 and 215 are for positioning the pins 50 in the decorative member 210 by positioning both ends of the pin 50, that is, both the stretchable parts 52b. .

  The inner diameters of the holes 214 and 215 have play with respect to the outer diameter of the expansion / contraction part 52 b of the protruding member 52.

  The hole portion 215 communicates with the arrangement hole 211 and the space portion 218, and the hole portion 214 communicates with the arrangement hole 211 and the space portion 219.

  In addition, on the outer surface of the decorative member 210, for example, a portion of the necklace 90 (see FIG. 5) or other accessory (for example, the connection ring 26 of the insertion member 20 and the like) A connecting ring (connecting portion) 216 for connecting to the end portion on the opposite side to the connecting portion is formed.

  Note that the bottom of the arrangement hole 211, that is, the inner peripheral surface serving as the back surface with respect to the outer surface of the decorative member 210 constitutes a reaction force applying portion 217 that applies a reaction force to the coil spring 40.

  In addition, an annular protrusion 220 is formed around the reaction force applying portion 217. The protrusion 220 receives the guide tube 60 via the buffer ring 70.

<Buffer ring>
The buffer ring 70 has an inner circumference set to be approximately the same as the outer diameter of the small-diameter portion 602 of the guide cylinder 60. In the state where the buffer ring 70 is extrapolated into the small-diameter portion 602, the hand is released from the buffer ring 70. Even so, the buffer ring 70 is prevented from dropping from the small diameter portion 602.

<Assembly>
The assembly of the constituent elements of the accessory fastener constituting jig 200 configured as described above to the decorative member 210 can be performed, for example, in the following manner.

  First, a part of the coil spring 40 is extrapolated to the coil spring holding portion 35 of the movable member 30. Here, since the outer diameter of the coil spring holding portion 35 is substantially equal to the inner diameter of the coil spring 40, the coil spring 40 does not fall even when the hand is released.

  Then, the coil spring 40 and the movable member 30 are inserted into the insertion hole 69 of the guide cylinder 60 from the coil spring 40 side.

  Subsequently, the first through-hole 63 of the guide tube 60 and the first through-hole 33 of the movable member 30 are aligned with each other, and the pin 50 is passed through these hole portions 63 and 33.

  At this stage, the movable member 30 and the guide cylinder 60 are connected to each other by the pin 50.

  Next, the buffer ring 70 is extrapolated to the innermost part with respect to the small diameter part 602 of the guide cylinder 60. Here, since the outer diameter of the small diameter portion 602 of the guide tube 60 is substantially equal to the inner diameter of the buffer ring 70, the buffer ring 70 does not fall even when the hand is released.

  Next, the guide tube 60, the buffer ring 70, the coil spring 40, the pin 50, and the movable member 30 are placed in the arrangement hole 211 of the decorative member 210 in a state where the pair of expansion / contraction portions 52b of the pin 50 are both compressed. The guide tube 60 is inserted in the direction of arrow C in FIG.

  During this insertion, the pair of expansion / contraction portions 52b of the pin 50 slides on the inner peripheral surface of the arrangement hole 211 until reaching the hole portions 214 and 215, and when reaching the hole portions 214 and 215, Projecting according to the urging force of the spring 53, and enter the holes 214 and 215, respectively.

  As a result of this insertion, the coil spring 40 is sandwiched between the urging receiving portion 36 of the movable member 30 and the reaction force applying portion 217 of the decorative member 210 and is in a compressed state.

  Further, the buffer ring 70 is sandwiched between the protrusion 220 of the decorative member 210 and the stepped portion located at the boundary between the small diameter portion 602 and the large diameter portion 601 of the guide tube 60. In addition, the operation unit 32 protrudes out of the decorative member 210.

  In this state, since the expansion / contraction portions 52b at both ends of the pin 50 are positioned in the holes 214 and 215, respectively, the movable member 30, the guide tube 60, the buffer ring 70, the coil spring 40, and the pin 50 are decorated. It does not fall off from the member 210.

<Operation>
The engagement operation and the engagement release operation between the engagement portion 31 and the insertion member 20 are the same as those in the first embodiment.

<Parts replacement operation>
Next, the operation when any part is replaced for some reason will be described.

  Here, some reason occurs when, for example, any part is broken or when any part is to be replaced with the same part having a different decorative property.

  Such a component replacement operation is performed with the insertion member 20 removed from the decorative member 210.

  In this state, for example, a pin (not shown) is inserted into the insertion hole 213 of the decorative member 210, and the tip of the inserted pin is further inserted into the hole 215 via the space portion 218. Thus, the expansion / contraction part 52b on one end side of the pin 50 is pushed and contracted. Then, the one end side of the pin 50 moves in the direction of arrow F in FIG. 4 according to the urging force of the coil spring 40, and the pin 50 tilts inside the first through hole 33. During this tilting, the telescopic portion 52 b on the other end side of the pin 50 tilts in the hole 214.

  Further, the expansion / contraction portion 52b on the one end side of the pin 50 moves in the direction of arrow F toward the inner peripheral wall of the arrangement hole 211 in accordance with the bias of the coil spring 40, and the pin 50 further tilts. As the pin 50 moves, the movable member 30 also moves in the direction of arrow F.

  In this state, by pulling out the operation portion 32 from the arrangement hole 211, the pin 50, the coil spring 40 and the guide cylinder 60 can be taken out from the arrangement hole 211 together with the operation portion 32.

  Therefore, any one of the pin 50, the coil spring 40, the guide tube 60, the movable member 30, and the decorative member 210 or two or more parts can be exchanged.

  The parts replacement operation can also be performed as follows.

  That is, as described above, for example, a pin (not shown) is inserted into the insertion hole 213 of the decorative member 210, and the tip of the inserted pin is further inserted into the hole 215 via the space 218, At the same time, the telescopic portion 52b on one end side of the pin 50 is pushed and contracted by the tip of the pin, and at the same time, for example, a J-shaped pin is inserted into the insertion hole 213 of the decorative member 210, It is inserted into the hole 214 through the portion 219, and the telescopic portion 52b on the other end side of the pin 50 is pushed and contracted by the tip of the pin.

  Then, the pin 50 moves in the direction of arrow F in FIG. 4 according to the urging force of the coil spring 40. For example, by further pulling out the operation portion 32 from the arrangement hole 211, the pin 50, The coil spring 40 and the guide cylinder 60 can also be taken out from the arrangement hole 211.

  In the latter operation (when two pins are inserted) of the above replacement operations, a hole is formed on the outer peripheral surface of the decorative member 210 on the space 219 side instead of using the J-shaped pin as described above. A hole (not shown) is provided in a portion facing the portion 214, a pin is inserted from the hole, and this pin is further inserted into the hole 214 through the space portion 219, and the other end side of the pin 50. This can be done more easily by compressing the expansion / contraction part 52b.

  According to the second embodiment as described above, in addition to the same effects as those of the first embodiment, there is also an effect that parts can be easily replaced.

[Third Embodiment]
FIG. 7 is a front cross-sectional view showing an accessory fastener 3000 including the accessory fastener constituting jig 300 according to the third embodiment.

  The accessory fastener 3000 shown in FIG. 7 differs from the accessory fastener 1000 according to the first embodiment only in the points described below, and is configured in the same manner as the accessory fastener 1000 in other points. Therefore, the same components as those in the accessory fastener 1000 are denoted by the same reference numerals, and the description thereof may be omitted.

  As shown in FIG. 7, the fastener constituting jig 300 for accessory according to the third embodiment is related to the insertion member 20 inserted into the decoration member 310 and the insertion member 20 inserted into the decoration member 310. The first and second engaging portions 331 and 341 for bringing the insertion member 20 into a state in which the insertion member 20 is prevented from being detached from the interior of the decorative member 310 by combining the first and second engaging portions 331 and 341 First and second operation portions 332 and 342 for releasing the engagement state with the insertion member 20 are provided.

  Here, the first engagement portion 331 and the first operation portion 332 are integrally formed with each other. That is, the first engaging portion 331 and the first operating portion 332 each constitute a part of the first movable member 330.

  Similarly, the second engagement portion 341 and the second operation portion 342 are integrally formed with each other. That is, the second engagement portion 341 and the second operation portion 342 constitute a part of the second movable member 340, respectively.

  Furthermore, the fastener constituting jig 300 for jewelry is a coil spring 40 that urges the first and second movable members 330 and 340, and the coil spring 40 and the first and second movable members 330 and 340 are decorated. And a pin 50 that prevents the member 310 from falling off.

  Hereinafter, each component will be described in detail.

<Pin>
In the present embodiment, the pin 50 is, for example, a spring bar (FIG. 6).

<Insert member>
As shown in FIG. 7, in the present embodiment, the insertion member 20 has a plurality of engaged grooves 21 formed therein. That is, the engaged grooves 21 are formed at a plurality of locations in the longitudinal direction (insertion direction) of the insertion member 20.

  In order to engage the engaging portions 331 and 341 and the insertion member 20, the engaging portions 331 and 341 are engaged with any two of the three engaged grooves 21. Since it only has to be engaged, it is possible to adjust the length of the necklace 90 (see FIG. 5) or other accessory (length in the direction of arrow D and arrow G in FIG. 7). .

  In addition, since the length can be adjusted in this way, the amount of protrusion of the insertion member 20 from the decorative member 310 is variable. As a result, the decorative member 310 has different dimensions (dimensions in the directions of arrows D and G in FIG. 7, in particular, dimensions from the position where the engaging portion 331 is arranged to the opening end of the insertion hole 313). There is also a secondary effect that a desired one (for example, a color or design that matches the preference) can be appropriately selected from the plurality of types of decorative members 310.

  Further, for example, among the plurality of engaged grooves 21, the engaging portions 331 and 341 may be engaged with the engaged groove 21 farthest from the distal end portion 22 and the engaged groove 21 in the middle. For example, even when the engagement state is released due to some sort of engagement, the engaging portions 331 and 341 are respectively separated from the other engaged grooves 21 on the distal end portion 22 side than previously engaged. By re-engaging, the coupling state of the insertion member 20 and the decorative member 310 can be maintained. Therefore, it is possible to reduce the possibility of dropping the necklace 90 or other accessories by some means.

  Furthermore, in the case of the present embodiment, each engaged groove 21 has an inclination that reduces the diameter toward the distal end portion 22 side. For this reason, when inserting the insertion member 20 in the arrow D direction, the engaging portions 331 and 341 can easily move to the engaged groove 21 in the next stage, but the insertion member 20 is in the arrow G direction. Even if pulled, the engaging portions 331 and 341 are unlikely to fall off the engaged grooves 21.

  The engagement strength between the engagement portions 331 and 341 and the engaged groove 21 (the strength that drops when the insertion member 20 is pulled in the arrow G direction) is the angle of the crest of the engaged groove 21, The height and the strength of the coil spring 40 are set by appropriately adjusting the height.
