  FIG. 3 shows the locking member 50, where (a) is a front view and (b) is a cross-sectional view taken along the line B-B of (a). As shown in FIG. 3, the locking member 50 has a substantially U-shaped plate 51 and an engagement / disengagement push button 52.

  The substantially U-shaped plate 51 is a member that functions as an operating body when locking and releasing the locking portion 51c and the locking recess 42c. The substantially U-shaped plate 51 has a pair of straight portions 51a and 51b. The straight portions 51a and 51b are formed to extend from the engagement and release button 52 in the -Y direction. In addition, the substantially U-shaped plate 51 has a locking portion 51 c which extends in the Z direction and can be engaged with and disengaged from the locking recess 25. The locking portion 51c is formed to connect the ends of the pair of straight portions 51a and 51b on the -Y side. The straight portions 51a and 51b and the locking portion 51c are formed of rod-like members having a rectangular cross section.

  The straight portion 51b and the locking portion 51c are integrally formed in the L-shaped portion 51d. The L-shaped portion 51 d is formed in an L-shape connecting the straight portion 51 a and the engagement / disengaging push button 52 and extending in the Y direction and the Z direction. A cutout portion 51e is provided inside the bent portion of the L-shaped portion 51d. By having such a notch portion 51e, when the L-shaped portion 51d is manufactured by bending a linear member, the bending process can be easily performed.

  The substantially U-shaped plate 51 is not limited to the above configuration. For example, the cross-sectional shape of the straight portions 51a and 51b or the locking portion 51c may be circular or polygonal other than square, instead of rectangular. The straight portions 51a and 51b and the locking portion 51c may be integrally formed or may be formed of different members. Further, in the locking member 50, the cutout portion 51e may not be provided.

  The engagement / disengagement push button 52 is circular when viewed from the Y direction, and is formed hollow to accommodate the biasing member 60. The engagement / disengagement push button 52 has a convex curved surface portion (a surface on the + Y side) 52a toward the outside, and a cylindrical portion 52b extending in the -Y direction from the periphery of the curved surface portion 52a. The curved surface portion 52 a is arranged to protrude from the surface on the + Y side of the clasp body 30 to the outside. The cylindrical portion 52 b is formed so as to be able to be accommodated in the concave portion 72 of the case 70. In addition, the engagement / disengagement push button 52 is not limited to the above-mentioned configuration, for example, the shape of the engagement / disengagement push button 52 as viewed from the Y direction is not limited to a circular shape, and may be an oval, an oval May be

  The biasing member 60 is a member that biases the locking portion 51c in the direction (Y direction) in which the locking portion 51c is always locked in the locking recess 25. The biasing member 60 is accommodated in the engagement / disengagement push button 52 and is disposed between a seat 80 and an engagement / disengagement push button 52 described later. Although a coil spring is used as the biasing member 60, it is not limited thereto.

  The case 70 is a member that accommodates the receiving member 40, the locking member 50, and the biasing member 60. FIG. 4 shows the case 70, where (a) is a plan view and (b) is a cross-sectional view taken along the line C-C of (a). As shown in FIG. 4, the case 70 has an insertion hole 71 and a recess 72. The case 70 is a substantially spherical casing. The case 70 is not limited to the above shape. In addition, the case 70 may have various decorations on the surface.

  The insertion hole 71 is a portion into which the receiving member 40 is inserted. The size of the bore of the insertion hole 71 is set to be slightly larger than the outer diameter of the receiving member 40, for example.

  The concave portion 72 is provided on the surface on the + Y side of the case 70, and is formed to be recessed in the -Y direction. The recess 72 is capable of receiving the engagement / disengagement push button 52. A seat 80 is formed on the bottom surface (the surface on the −Y side) of the recess 72.

  The seat 80 is integrally formed with the case 70, and is disposed between the receiving member 40 and the engagement / disengagement button 52 (see FIG. 1 (b)). Since the seat 80 is integrally formed with the case 70 in this manner, it is not necessary to prepare a member for forming the seat 80 separately from the case 70, so that an increase in the number of parts of the clasp 10 can be avoided. The increase in the manufacturing cost of the clasp 10 is suppressed. An end of the other end of the biasing member 60 accommodated in the engagement and release push button 52 abuts on the seat 80 at one end. Therefore, the biasing member 60 is restricted from projecting to the -Y side of the seat 80.

  The seat 80 is formed in a plane parallel to the XZ plane. The seat 80 also has an opening 81. The opening 81 is formed by penetrating the seat 80 in the thickness direction (Y direction). The opening 81 is formed slidably and insertably along the locking direction (Y direction) of the locking member 50.

  The opening 81 is formed to extend in the Z direction, and has a pair of straight portions 81a and 81b arranged in parallel along the X direction. The straight portion 81a is configured such that the substantially U-shaped plate 51 can slide while the side surface 51f on the + X side of the straight portions 51a and 51b of the locking member 50 is in contact. The straight portion 81b is configured such that the substantially U-shaped plate 51 can slide while the side surface 51g on the -X side of the straight portions 51a and 51b is in contact.

  With such a configuration of the opening 81, when the locking member 50 moves in the locking direction, the side surface 51a and the like are brought into contact with and guided by the linear portion 81a and the like of the opening 81, The blurring of the moving direction (X direction) of the member 50 is suppressed. Thus, the engagement of the locking portion 51c can be performed more reliably.

  The seat 80 is not limited to the above-described configuration. The seat 80 may be formed to have an uneven surface, or may be formed to be inclined with respect to the XZ plane. Also, instead of being formed in a planar shape, for example, the seat portion 80 may be formed in a piece shape having a projecting piece that protrudes inward from the end on the -Y side of the recess 72. The matters regarding the seat 80 may be applied to the seats 380 and 480 described later.

  Further, the opening 81 is not limited to the above configuration. For example, the straight portions 81a and 81b may be configured to have curved portions. Further, instead of the configuration in which both the side surfaces 51f and 51g on the + X side and -X side of the substantially U-shaped plate 51 can slide, only one of the side surfaces 51f and 51g may be formed to be slidable. . In this case, one of the pair of straight portions 81a and 81b may not be provided. When the cross-sectional shapes of the straight portions 51a and 51b of the locking member 50 are formed other than rectangular, the opening 81 may have the same shape as the outer edge of the cross section of the straight portions 51a and 51b. Also, the opening 81 may be formed so that the side surfaces 51a and 51b on the + X side or the −X side of the substantially U-shaped plate 51 slide on the side surface on the + X side or the −X side of the opening 81 . Further, the locking member 50 inserted into the opening 81 is not limited to sliding relative to the opening 81 along the locking direction, and the locking member 50 and the opening 81 abut each other. It may be configured not to move.

  An annular protrusion 74 protruding in the −X direction is provided on the + X side inner wall surface of the case 70. The protrusions 74 are formed to surround the placement area of the adhesive (not shown). This prevents the adhesive (not shown) from spreading during bonding. In addition, whether or not to provide such a projection 74 on the case 70 is optional.

  The mounting ring 90 is disposed on the proximal side (+ X side) of the case 70. The mounting ring 90 is a member for connecting the case 70 to the decorative portion 2. The mounting ring 90 is formed in an annular shape, and protrudes from the central portion of the + X side surface of the case 70. To the mounting ring 90, for example, an annular member 4 (see FIG. 12) connected to an end of the decorative portion 2 is connected. Note that whether or not the mounting ring 90 is provided on the clasp body 30 is optional.

  Next, the operation of coupling and uncoupling of the clasps 10 will be described with reference to FIG. FIG. 5 shows a state in which the insertion member 20 and the clasp main body 30 are connected, and is a cross-sectional view taken along a line corresponding to the line D-D in FIG.

  When connecting the insertion member 20 and the clasp main body 30 to each other, the insertion member 20 is made to approach the clasp main body 30, and the distal end portion 21 of the insertion member 20 is inserted through the insertion port 43 (see FIG. 1). Insert into clasp body 30. The distal end portion 21 is smoothly introduced since the cross-sectional area is gradually increased from the distal end side to the proximal end side. The insertion member 20 moves in the + X direction while pressing the locking portion 51c in the -Y direction on the outer peripheral surface, and when the locking recess 25 reaches the locking portion 51c, as shown in FIG. 5, the biasing member By the elastic force of 60, the locking portion 51c is protruded and locked in the locking recess 25, and the connection is completed.

  In order to release the connection, the insertion member 20 is pulled in the pulling direction (−X direction) while pressing the engagement / disengagement push button 52 projecting in the + Y direction from the surface of the clasp main body 30 in the −Y direction. As a result, the substantially U-shaped plate 51 of the locking member 50 is pushed down in the -Y direction, the locking portion 51c is released from the locking recess 25, and the locked state is released. In this state, by pulling the insertion members 20 out of the clasp body 30, the mutual connection is released.

  Subsequently, an example of an assembly procedure of the clasp 10 will be described. In addition, since the insertion member 20 is integrally formed, the assembly procedure of the clasp main body 30 will be described below. FIG. 6 is a view showing an example of an assembly procedure of the clasp body 30. As shown in FIG. First, the biasing member 60 is inserted into the locking member 50. At this time, the biasing member 60 is accommodated inside the engagement / disengagement push button 52 along the direction indicated by the arrow in FIG. 6 (a).

  Next, as shown in FIG. 6 (b), the locking member 50 and the biasing member 60 are disposed in the recess 72 of the case 70, and the engagement / disengagement push button 52 is in the direction of the arrow in FIG. And the biasing member 60 is compressed. Thereby, the locking portion 51 c is pushed down in the −Y direction. In this state, as shown in FIG. 6C, the receiving member 40 is inserted into the inside of the case 70 from the adhesive portion 41 side through the insertion hole 71. At this time, the compressed biasing member 60 abuts the seat portion 80 on the end portion on the -Y side, and the biasing member 60 is prevented from projecting to the -Y side of the seat portion 80, and the inside of the case 70 A space S is formed in which the receiving member 40 can be inserted. Therefore, when the receiving member 40 is inserted into the case 70, the biasing member 60 is prevented from being obstructed, so that the clasp main body 20 can be assembled easily and reliably.

  The locking portion 51 c of the locking member 50 is fitted in the notch 42 c by the elastic force of the biasing member 60 and protrudes in the receiving member 40 in the + Y direction. In this state, the receiving member 40 is housed in the case 70, and the assembly of the clasp body 30 is completed.

  According to such a clasp 10, even when the case where the case lid and the case main body are integrally formed is adopted, it can be assembled easily and reliably.
