The clasp 1000 mainly includes an insertion member 1100 and a casing 1200. The insertion member 1100 is inserted into the opening 1230 of the casing 1200 and fixed inside the casing 1200, so that a clasp is formed. The

  First, referring to FIG. 4, the insertion member 1100 has a bar shape and is inserted into the housing 1200 and fixed. In order to facilitate insertion, a tapered head portion 1150 is formed at the insertion side end portion, and a connecting portion 1160 having a ring portion 1170 to be connected to an accessory or the like is formed at the opposite end portion. A concave engaging groove 1180 is formed in the central circumferential portion. On the other hand, the housing 1200 has a box shape, and is mainly composed of a lid body 1210 having an entire lower surface opened and a bottom body 1220 fitted into the lid body and having an entire upper surface opened. An opening 1230 having a diameter slightly longer than the cross-sectional diameter of the insertion member 1100 is formed on one side surface in the longitudinal direction of the lid body 1210. The bottom body 1220 and the lid body 1210 are connected to each other via a support shaft 1240, and the bottom body 1220 can pivot about the support shaft 1240. Further, a pressing portion 1250 made of irregularities on a plurality of lines is formed on one surface side of the bottom body 1220.

  Next, referring to FIG. 5, two guide portions 1260 having an inner diameter substantially the same as the outer diameter of the insertion member 1100 are formed inside the bottom body 1220. One side surface corresponding to the opening 1230 includes a semicircular locking portion 1270 having a diameter substantially the same as the outer diameter of the engaging groove portion 1180 of the insertion member 1100. Further, a substantially U-shaped coil spring 1280 is wound around the outer periphery of the support shaft 1240, and the bottom body 1220 is urged about the support shaft 1240 in the counterclockwise direction in FIG. ing.

Next, a procedure for connecting the insertion member 1100 and the housing 1200 in the clasp 1000 will be described.
First, the user inserts the head portion 1150 of the insertion member 1100 into the opening 1230 of the housing 1200. Further, when the insertion member 1100 is pushed into the housing 1200, the insertion member 1100 advances into the housing 1200 with its outer peripheral surface contacting the inner peripheral surface of the guide portion 1260, and eventually the head of the insertion member 1100. The tip of the part 1150 contacts the coil spring 1280. Next, the coil spring 1280 is pushed up by the insertion member 1100, and when the engagement groove 1180 of the insertion member 1100 reaches the opening 1230 of the bottom body 1220 in this state, the locking portion 1270 is engaged by the biasing force of the coil spring 1280. Engages with the groove 1180. As a result, the insertion member 1100 is fixed to the housing 1200.

  On the other hand, when the insertion member 1100 and the housing 1200 are separated from each other, first, the user presses the pressing portion 1250 of the bottom body 1220 with a finger. Accordingly, the bottom body 1220 pivots in the clockwise direction in FIG. 5 around the support shaft 1240 against the urging force of the coil spring 1280. As a result, the engaging portion 1270 of the bottom body 1220 engaged with the engaging groove portion 1180 of the insertion member 1100 is detached from the engaging groove portion 1180. When the user pulls out the insertion member 1100 from the housing 1200 in this state, the insertion member 1100 and the housing 1200 are separated from each other.

  By applying the above clasp 1000 to an accessory such as a necklace, it is possible to provide an accessory that can be easily connected.

  The insertion member 20 has a rod shape, a tapered head portion 40 formed at one end, a connecting portion 60 formed at the other end and having a hole, and penetrating through the hole of the connecting portion, so as to be a rosary of accessories. The ring part 70 to be connected and the engaging groove part 50 provided in a concave shape on the outer periphery are provided.

  The casing 30 has a box shape, and is mainly provided in the same shape of the first frame 80 and the second frame 90 and inside these frames, and has a diameter slightly larger than the outer periphery of the insertion member 20 at one end. And a support 100 provided with an opening 110 having Moreover, the connection part 130 which has a hole, and the ring part 140 which connects this connection part and the bead of an accessory are provided in the other end of the support body 100 (refer FIG. 2). The first frame 80 has a flat part 810 and an inclined part 820. Although not shown, the second frame 90 similarly has a flat portion 910 and an inclined portion 920. The first frame 80 and the second frame 90 can pivot about the support shaft 120.

Next, the structure of each member constituting the housing 30 will be described with reference to FIG. The support body 100 includes a cylindrical first support body (support member) 200 and a square second support body 300 that are integrally formed. The first support 200 includes a pair of grooves 200a formed in the upper and lower directions in addition to the opening 110. The second support 300 includes a pair of holes 300a formed on both side surfaces, a space 300b penetrating vertically, and a pair of spring accommodating portions 300c for accommodating the pair of coil springs 150, respectively. Note that the pair of holes 300a and the space 300b communicate with each other.

  The second frame 90 includes a first cutout 90a formed on one side surface in the longitudinal direction, a pair of second cutouts 90b formed on both side surfaces in the short side direction, and a locking portion extending from the bottom surface. 90c and a protrusion 90d having a hole 90e. Here, the inner diameter of the arc-shaped first notch 90a is substantially the same as the outer diameter of the first support body 200 of the support body 100, and the inner diameters of the arc-shaped second notch 90b and the hole 90e are the support shafts. The locking portion 90c has a shape that can be inserted into the groove 200a of the first support 200, and the protruding portion 90d has a shape that can be inserted into the space 300b. Although not shown, the first frame 80 similarly includes a first cutout 80a, a pair of second cutouts 80b, a locking portion 80c, and a protruding portion 80d including a hole 80e. Have.

  Next, a method for assembling each member constituting the housing 30 will be described. First, after the ring portion 140 is connected to the connecting portion 130 of the support body 100, the coil spring 150 is accommodated in each of the pair of spring accommodating portions 300c. Thereafter, the first frame 80 and the second frame 90 are combined so as to sandwich the support 100. At this time, the tip of the first support 200 is disposed between the first cutout 80 a of the first frame 80 and the first cutout 90 a of the second frame 90. Furthermore, in a state where the protrusion 80d of the first frame 80 and the protrusion 90d of the second frame 90 are inserted into the space 300b of the support 100, the hole 300a of the second support 300 of the support 100 A hole defined by the second cutout 90b of the first frame 80 and the second cutout 80b of the second frame 90, a hole 80e of the protrusion 80d of the first frame 80, and a second The holes 90e of the protrusions 90d of the frame 90 are arranged in a straight line. Further, the locking portion 80 c of the first frame 80 and the locking portion 90 c of the second frame 90 are engaged with the grooves 200 a of the first support 200, respectively. Finally, if the support shaft 120 is passed through the holes 300a, 80e, 90e from the holes defined by the second cutouts 80b, 90b of the first frame 80 and the second frame 90, the housing 30 Is formed.

  When the housing 30 is formed, the connecting portion 130 of the support 100 is exposed to the outside by the inclined portions 820 and 920 of the first frame 80 and the second frame 90. In addition, the coil spring 150 urges the locking portion 80 c of the first frame 80 and the locking portion 90 c of the second frame 90 in the direction in which the locking portion 80 c is inserted into the groove 200 a of the first support 200.

Next, a procedure for connecting the insertion member 20 of the clasp 10 to the housing 30 or a procedure for releasing the connection will be described with reference to FIGS.
First, the user inserts the head 40 of the insertion member 20 into the opening 110 of the housing 30 (see FIG. 3A). When inserted, the insertion member 20 is further pushed into the opening 110. Eventually, the head 40 of the insertion member 20 comes into contact with the locking portion 80c of the first frame 80 and the locking portion 90c of the second frame 90 (see FIG. 3B). Accordingly, the first frame 80 and the second frame 90 pivot in a direction against the urging force of the coil spring 150 (see FIG. 3C). Thereafter, the insertion member 20 advances to the inside of the support body 100 with the outer periphery thereof in contact with the locking portions 80c and 90c, and when the engagement groove 50 and the locking portions 80c and 90c of the insertion member 20 are aligned, Due to the urging force of the coil spring 150, the locking portions 80c and 90c are engaged with the engaging groove portion 50 (see FIG. 3D). As a result, the insertion member 20 is fixed, and the connection between the insertion member 20 and the housing 30 is completed.

On the other hand, when separating the insertion member 20 and the housing 30, first, the user applies a force to the housing 30 in the direction shown in FIG. 3 (see FIG. 3 (e)). Accordingly, the first frame 80 and the second frame 90 pivot against the urging force of the coil spring 150, and the engagement of the locking portions 80c and 90c with the engaging groove 50 is released. If the insertion member 20 is pulled in this state, it is pulled out from the housing 30. As a result, the insertion member 20 and the housing 30 are separated (see FIG. 3A).
As described above, the insertion member 20 and the housing 30 of the clasp 10 can be connected and separated by a simple procedure.

  In addition, the material of each member which comprises the clasp 10 is not specifically limited, You may use arbitrary materials, such as various metals and resin. Similarly, the manufacturing method of each member may also use arbitrary processing methods, such as shaving, bonding, etching, mold processing using a die or a press.

The clasp 10 having the above structure has the following two significant advantages.
A case is assumed in which a force is applied to the insertion member 20 at a right angle or an oblique direction with respect to the insertion direction due to an accessory being pulled or the like in a state where the insertion member 20 and the housing 30 are connected. In this case, this force acts only on the support 100. Therefore, no force acts on the coil spring 150 and the locking portions 80c and 90c having the function of fixing the insertion member 20. Therefore, the fixing of the insertion member 20 is not released and is held as it is. That is, by configuring the support body 100 that supports the insertion member 20 and the locking portions 80c and 90c that fix the insertion member 20 as separate members, the connection is prevented from being released against the user's will. And a stable connection can be provided.

  Furthermore, since the housing 30 is composed of the first frame 80 and the second frame 90 having the same shape, the clasp 10 can be suitably applied to accessories such as a necklace. That is, when the housing 30 is used as an accessory pendant head, even if the accessory is twisted and the housing 30 is inverted, the front and back of the housing 30 have the same shape, and the appearance of the accessory is not impaired. Furthermore, the processing cost of the housing can be reduced.

Although the structure of the clasp 10 according to the embodiment of the present invention has been described above, the present invention is not limited to this structure.
For example, in the present embodiment, the cross section of the insertion member 20 and the shape of the opening 110 are substantially perfect circles, but may be any shape including an ellipse or a square instead. In the present embodiment, the first frame 80 and the second frame 90 have the same shape, but both do not necessarily have the same shape. Alternatively, if both internal shapes are the same, they may have different external shapes, and may have different colors and patterns. Alternatively, the first frame 80 and the second frame 90 may be integrated.

  As mentioned above, although this invention was demonstrated using embodiment shown in drawing, these are only an illustration and those skilled in this technical field can variously be within the range which does not deviate from the range and the meaning of this invention. It will be understood that modifications and variations are possible. Accordingly, the scope of the invention should not be determined by the described embodiments, but by the technical spirit described in the claims.
