本発明はクラスプ（連結具）に関し、より詳細には、ネックレス、ブレスレット等のアクセサリに適用されるクラスプに関する。   The present invention relates to a clasp (connector), and more particularly to a clasp applied to accessories such as a necklace and a bracelet.

添付図面の図６ないし図７を参照して、特許文献１が示すようなネックレス、ブレスレット等のアクセサリに使用されるクラスプ（連結具）について説明をする。このクラスプ１０００は、主に挿入部材１１００と筐体１２００とから構成され、挿入部材１１００が、筐体１２００の開口部１２３０に挿入され、筐体１２００の内部に固定されることでクラスプが形成される。   With reference to FIGS. 6 to 7 of the accompanying drawings, a clasp (connector) used for accessories such as a necklace and a bracelet as shown in Patent Document 1 will be described. 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

まず、図６を参照すると、挿入部材１１００は棒形状を有し、筐体１２００に挿入され、固定される役割を果たす。挿入を容易にするために挿入側端部に先細の頭部１１５０が形成され、反対側端部にアクセサリ等に連結されるための環部１１７０を有する連結部１１６０が形成されている。そして、中央円周部分に凹状の係合溝部１１８０が形成されている。一方、筐体１２００は箱形状を有し、下面全体を開口した蓋体１２１０（図７参照）と、該蓋体の内部に勘合し、かつ上面全体を開口した底体１２２０とから主に構成される。蓋体１２１０の長手方向の一側面には、挿入部材１１００の断面直径よりも若干長い直径を有する開口部１２３０が形成されている。底体１２２０と蓋体１２１０とは、支軸１２４０を介して相互に連結され、底体１２２０は支軸１２４０を中心にピボット動作が可能である。また、底体１２２０の表面片側には複数の線上の凹凸からなる押圧部１２５０が形成されている。   First, referring to FIG. 6, 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 (see FIG. 7) having an entire lower surface opened, and a bottom body 1220 fitted into the lid body and having an entire upper surface opened. Is done. 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.

次に、図７を参照すると、底体１２２０の内側には、挿入部材１１００の外径と略同一の内径を有する２つのドーム部１２６０が形成されている。開口部１２３０と対応する一側面は、挿入部材１１００の係合溝部１１８０の外径と略同一の直径を有する半円状の係止部１２７０を備える。さらに、支軸１２４０の外周には略コの字状のコイルバネ１２８０が巻かれており、このコイルバネ１２８０により底体１２２０はこの図で反時計回りの方向に支軸１２４０を中心にして付勢されている。   Next, referring to FIG. 7, two dome 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.

次に、クラスプ１０００における挿入部材１１００と筐体１２００との接続手順について説明する。
最初に、ユーザが挿入部材１１００の頭部１１５０を、筐体１２００の開口部１２３０に挿入する。さらに、挿入部材１１００を筐体１２００の内部に押し込むと、挿入部材１１００は自身の外周面をドーム部１２６０の内周面に接触しながら筐体１２００の内部に進行し、やがて挿入部材１１００の頭部１１５０の先端がコイルバネ１２８０に接触する。次いで、コイルバネ１２８０が挿入部材１１００によって押し上げられ、その状態で挿入部材１１００の係合溝部１１８０が底体１２２０の開口部１２３０に達した時点で、係止部１２７０がコイルバネ１２８０の付勢力によって係合溝部１１８０に係合する。その結果、挿入部材１１００は筐体１２００に固定される。 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 dome 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.

一方、挿入部材１１００と筐体１２００とを相互に分離させる場合には、まず、ユーザが底体１２２０の押圧部１２５０を指で押す。それに応じて、底体１２２０がコイルバネ１２８０の付勢力に逆らって支軸１２４０を中心に図５において時計回りの方向にピボット動作する。それにより、挿入部材１１００の係合溝部１１８０に係合していた底体１２２０の係止部１２７０が係合溝部１１８０から離脱する。この状態でユーザが挿入部材１１００を筐体１２００から引き抜けば、挿入部材１１００と筐体１２００とが相互に分離する。   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.

以上のクラスプ１０００をネックレス等のアクセサリに適用すれば、接続が容易なアクセサリを提供することが可能となる。   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.

しかしながら、上記の構造を有するクラスプには以下に示すような不都合がある。   However, the clasp having the above structure has the following disadvantages.

クラスプ１０００の筐体１２００の形状が表裏同一ではない。このクラスプをネックレス等のアクセサリに適用した場合を想定する。一般に、クラスプ１０００がペンダントヘッドの役割を果たし、筐体１２００の蓋体１２１０側が表になるようにユーザに装着されるが、この時にアクセサリがねじれると、クラスプ１０００が反転して底体１２２０側が表になってしまう。これでは、アクセサリの美観が大きく損なわれてしまう。   The shape of the casing 1200 of the clasp 1000 is not the same. Assume that this clasp is applied to an accessory such as a necklace. In general, the clasp 1000 serves as a pendant head and is attached to the user so that the lid 1210 side of the housing 1200 faces up. However, when the accessory is twisted at this time, the clasp 1000 is inverted and the bottom body 1220 side is faced up. Become. This greatly damages the aesthetics of the accessory.

仮にこの構造で表裏同一の筐体を有するようにクラスプを作成する場合には、筐体の裏面の１１２０の形状を筐体の表面１２１０と同一のものにする必要がある。そのため、クラスプの厚みが増してしまい、薄型のクラスプを提供することができなくなる。   If the clasp is created to have the same front and back housings with this structure, the shape of the back surface 1120 of the housing must be the same as the front surface 1210 of the housing. For this reason, the thickness of the clasp increases, and a thin clasp cannot be provided.

図１ないし図５の添付図面を参照して、本発明の第１の実施形態に係るクラスプの構造を以下に詳細に説明する。
図１は、本発明の一実施形態に係るクラスプ１０を示している。図示のようにクラスプ１０は、主に挿入部材２０と筐体３０とから構成される。 A clasp structure according to a first embodiment of the present invention will be described in detail below with reference to the accompanying drawings of FIGS.
FIG. 1 shows a clasp 10 according to an embodiment of the present invention. As shown in the figure, the clasp 10 is mainly composed of an insertion member 20 and a housing 30.

挿入部材２０は棒形状を有し、一端に形成された先細状の頭部４０と、他端に形成され、孔を有する連結部６０と、該連結部の孔を貫通し、アクセサリの数珠に連結する環部７０と、外周に凹状に設けられた係合溝部５０と、を備える。   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.

筐体３０は中空の箱形状を有し、主に、ほぼ同一の外形を有する第１のフレーム８０および第２のフレーム９０と、当該第１および第２のフレームの一端に形成された開口部１００と、その他端側に設けられ、第２のフレームに設けられた（詳細は図２を参照）連結部１１０および環部１２０と、当該第１および第２のフレームを相互に連結する支軸１３０と、から構成される。また、筐体３０の当該他端側はスリットのような構造となっており、これにより、第１のフレーム８０および第２のフレーム９０は支軸１３０を中心に相互にピボット運動が可能である。   The housing 30 has a hollow box shape, and mainly includes a first frame 80 and a second frame 90 having substantially the same outer shape, and an opening formed at one end of the first and second frames. 100, a connecting portion 110 and a ring portion 120 provided on the other end side and provided on the second frame (see FIG. 2 for details), and a supporting shaft for connecting the first and second frames to each other 130. In addition, the other end side of the housing 30 has a structure like a slit, so that the first frame 80 and the second frame 90 can pivot about the support shaft 130. .

次に、図２を参照して筐体３０の内部構造について説明する。第１のフレーム８０は、両側面に支軸１３０を挿入するための挿入穴１９０と、裏面に挿入部材２０を固定するための係止部１４０（図３参照）と、同じく裏面に突出するよう形成されたバネを固定するためのバネ台１５０（図３参照）と、を備える。一方、第２のフレーム９０は、側面から上面にかけてドーム状に形成されるドーム部１６０と、裏面から突出するように形成される、支軸１３０を挿入するための穴を有する一対の支軸固定部１７０，１７０と、同じく裏面から突出するバネ台１８０と、を有する。これらの第１のフレーム８０と第２のフレーム９０との間に、コイルバネ２００が配置される。このコイルバネ２００は、両端がそれぞれ第１のフレーム８０のバネ台１５０と、第２のフレーム９０のバネ台１８０とに固定され、通常、双方のフレームを、支軸１３０を中心に開口部１００を閉じる方向に付勢する。   Next, the internal structure of the housing 30 will be described with reference to FIG. The first frame 80 has an insertion hole 190 for inserting the support shaft 130 on both side surfaces, a locking portion 140 (see FIG. 3) for fixing the insertion member 20 on the back surface, and also protrudes on the back surface. A spring base 150 (see FIG. 3) for fixing the formed spring. On the other hand, the second frame 90 has a dome portion 160 formed in a dome shape from the side surface to the upper surface, and a pair of support shafts having a hole for inserting the support shaft 130 formed so as to protrude from the back surface. Parts 170, 170, and a spring base 180 that also projects from the back surface. A coil spring 200 is disposed between the first frame 80 and the second frame 90. Both ends of the coil spring 200 are fixed to the spring base 150 of the first frame 80 and the spring base 180 of the second frame 90, respectively. Usually, both the frames are formed with the opening 100 around the support shaft 130. Energize in the closing direction.

次に、図３（ａ）ないし（ｅ）を参照して、上記クラスプ１０の挿入部材２０を筐体３０に接続する手順、並びに接続を解除する手順について説明する。
まず、ユーザが挿入部材２０の頭部４０を筐体３０の開口部１００に挿入する（図３（ａ）参照）。挿入すると、さらに挿入部材２０を開口部１００から筐体３０の中に押し込む。やがて、挿入部材２０の頭部４０が第１のフレーム８０の係止部１４０に接触する（図３（ｂ）参照）。それに応じて、第１のフレーム８０がコイルバネ２００の付勢力に逆らう方向にピボット運動をする（図３（ｃ）参照）。その後、挿入部材２０は、その頭部４０の外周が係止部１４０の先端と接触した状態で、第２のフレーム９０のドーム部１６０の内部に進み、挿入部材２０の係合溝部５０と筐体３０の係止部１４０とが並ぶと、コイルバネ２００の付勢力によって、係止部１４０が係合溝部５０に係合する（図３（ｄ）参照）。その結果、挿入部材２０が固定され、挿入部材２０と筐体３０との接続が完了する。 Next, a procedure for connecting the insertion member 20 of the clasp 10 to the housing 30 and 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 100 of the housing 30 (see FIG. 3A). When inserted, the insertion member 20 is further pushed into the housing 30 from the opening 100. Eventually, the head 40 of the insertion member 20 comes into contact with the locking portion 140 of the first frame 80 (see FIG. 3B). In response to this, the first frame 80 pivots in a direction against the urging force of the coil spring 200 (see FIG. 3C). Thereafter, the insertion member 20 advances to the inside of the dome portion 160 of the second frame 90 in a state where the outer periphery of the head 40 is in contact with the tip of the locking portion 140, and the insertion groove 20 and the housing of the insertion member 20. When the locking portion 140 of the body 30 is aligned, the locking portion 140 is engaged with the engagement groove portion 50 by the biasing force of the coil spring 200 (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.

一方、挿入部材２０と筐体３０とを相互に分離させる場合には、まず、ユーザは筐体３０に図３に示す方向に力を加える（図３（ｅ）参照）。それに応じて、第１のフレーム８０がコイルバネ２００の付勢力に逆らってピボット運動をし、係止部１４０の係合溝部５０への係合が解除される。この状態で挿入部材２０を引っ張れば筐体３０から引き抜くことができる。その結果、挿入部材２０と筐体３０とが分離される（図３（ａ）参照）。
このように、クラスプ１０の挿入部材２０と筐体３０とは、簡単な手順で接続および分離が可能である。 On the other hand, when the insertion member 20 and the housing 30 are separated from each other, first, the user applies a force to the housing 30 in the direction shown in FIG. 3 (see FIG. 3E). Accordingly, the first frame 80 pivots against the urging force of the coil spring 200, and the engagement of the locking portion 140 with the engagement groove 50 is released. If the insertion member 20 is pulled in this state, it can be 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.

なお、クラスプ１０を構成する各部材の材料は特に限定されるものではなく、各種金属、樹脂等の任意の材料を用いてよい。同様に、各部材の製法も削り、張り合わせ、エッチング、金型やプレス機を用いたモールド加工等、任意の加工手法を用いてよい。   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.

以上の構造を有するクラスプ１０では、挿入部材２０と筐体３０とを接続したときに、挿入部材２０の軸方向の中心と、筐体３０の支軸１３０の中心と、筐体３０の軸方向の中心とが同一線上に配列される。そのため、筐体３０を薄型形状にすることができる。このクラスプをネックレス、ブレスレット等のアクセサリに適応した場合に当該アクセサリの美観を損ねることがない。   In the clasp 10 having the above structure, when the insertion member 20 and the housing 30 are connected, the center of the insertion member 20 in the axial direction, the center of the support shaft 130 of the housing 30, and the axial direction of the housing 30. Are arranged on the same line. Therefore, the housing 30 can be made thin. When this clasp is applied to an accessory such as a necklace or a bracelet, the appearance of the accessory is not impaired.

さらに、筐体３０がほぼ同一の外形を有する第１のフレーム８０および第２のフレーム９０で構成されているため、クラスプ１０をネックレス等のアクセサリに好適に適用することができる。つまり、筐体３０をアクセサリのペンダントヘッドとして使用した場合、アクセサリがねじれて筐体３０が反転しても、筐体３０の表裏がほぼ同一形状のためアクセサリの美観を損ねることがない。   Furthermore, since the housing 30 is composed of the first frame 80 and the second frame 90 having substantially the same outer 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 are substantially the same shape, and the appearance of the accessory is not impaired.

以上に渡り、本発明の第１の実施形態に係るクラスプ１０の構造を説明したが、本発明はこの構造に限定されるものではない。以下に、本発明の第２の実施形態並びに第３の実施形態に係るクラスプの構造についてそれぞれ図４および図５を用いて説明する。なお、これらの図面に示すクラスプの各部材において、第１の実施形態に係るクラスプ１０と同一のものには同一の参照番号を付与している。   Although the structure of the clasp 10 according to the first embodiment of the present invention has been described above, the present invention is not limited to this structure. The clasp structure according to the second embodiment and the third embodiment of the present invention will be described below with reference to FIGS. 4 and 5, respectively. In addition, in each member of the clasp shown in these drawings, the same reference numeral is given to the same member as the clasp 10 according to the first embodiment.

まず、図４は、本発明の第２の実施形態に係るクラスプ３００の接続時の断面を示している。第２の実施形態に係るクラスプ３００は、第１の実施形態に係るクラスプ１０とは係止構造が異なる。第１の実施形態に係るクラスプ１０の第１のフレーム８０がその裏面に係止部１４０を備えているが、第２の実施形態に係るクラスプ３００の筐体３１０は係止部を備えていない。その代わりに、筐体３１０の開口３２０の周辺部が係止部の機能を果たす。図示のように、筐体３１０の開口３２０の周辺部がコイルバネ２００からの付勢力によって、挿入部材２０の係合溝部５０に係合する。これにより、挿入部材２０が筐体３１０に接続される。第２の実施形態に係るクラスプ３００は、筐体３１０内部に係止部を備える必要がないため、第１の実施形態に係るクラスプ１０の筐体３０よりも筐体３１０を小型にすることができる。   First, FIG. 4 shows a cross section of the clasp 300 according to the second embodiment of the present invention when connected. The clasp 300 according to the second embodiment differs from the clasp 10 according to the first embodiment in the locking structure. The first frame 80 of the clasp 10 according to the first embodiment includes the locking portion 140 on the back surface, but the casing 310 of the clasp 300 according to the second embodiment does not include the locking portion. . Instead, the peripheral part of the opening 320 of the housing 310 functions as a locking part. As illustrated, the peripheral portion of the opening 320 of the housing 310 is engaged with the engagement groove portion 50 of the insertion member 20 by the urging force from the coil spring 200. Thereby, the insertion member 20 is connected to the housing 310. Since the clasp 300 according to the second embodiment does not need to include a locking portion inside the casing 310, the casing 310 can be made smaller than the casing 30 of the clasp 10 according to the first embodiment. it can.

次に、図５（ａ）は、本発明の第３の実施形態に係るクラスプ４００の接続時の断面を示している。第３の実施形態に係るクラスプ４００は、第１の実施形態に係るクラスプ１０のようなコイルバネ２００を有していない。その代わりにダブルトーションバネ４１０を有している。このダブルトーションバネ４１０を図５（ｂ）に示す。この図に示すダブルトーションバネ４１０は２つのねじり部分４１０ａ，４１０ａを有し、そのねじり部分の間の部分４１０ｂが略コの字形状を形成しており、さらに、当該バネの両端がそれぞれ９０°折り曲げられ支軸部４２０，４２０を構成している。 Next, FIG. 5A shows a cross-section when the clasp 400 according to the third embodiment of the present invention is connected. The clasp 400 according to the third embodiment does not have the coil spring 200 like the clasp 10 according to the first embodiment. Instead, a double torsion spring 410 is provided. The double torsion spring 410 is shown in FIG. The double torsion spring 410 shown in this figure has two torsional portions 410a and 410a, the portion 410b between the torsional portions forms a substantially U-shape, and both ends of the spring are 90 ° each. The support shafts 420 and 420 are bent.

ダブルトーションバネ４１０のねじり部分４１０ａ，４１０ａの間の部分４１０ｂが略コの字形状を形成しているのは、挿入部材２０の挿入動作を阻害しないためである。また、支軸部４２０は第１のフレーム８０と第２のフレーム９０とをピボット動作可能に連結する機能を果たす。このクラスプ４００では、支軸１３０が不要となり、部品点数の削減に貢献する。また、筐体３０の内部に溝を形成し、ダブルトーションバネ４１０の支軸部４２０，４２０をその溝にはめ込むようにすれば、筐体３０から外部に支軸部４２０の先端が露出しなくなるため、よりスマートな外観を提供することができる。   The reason why the portion 410b between the torsional portions 410a and 410a of the double torsion spring 410 forms a substantially U-shape is that the insertion operation of the insertion member 20 is not hindered. Further, the support shaft portion 420 functions to connect the first frame 80 and the second frame 90 so as to be pivotable. In this clasp 400, the support shaft 130 becomes unnecessary, which contributes to a reduction in the number of parts. Further, if a groove is formed inside the housing 30 and the support shaft portions 420 and 420 of the double torsion spring 410 are fitted into the groove, the tip of the support shaft portion 420 is not exposed to the outside from the housing 30. Therefore, a smarter appearance can be provided.

以上、本発明を図面に示した実施形態を用いて説明したが、これらは例示的なものに過ぎず、本技術分野の当業者ならば、本発明の範囲および趣旨から逸脱しない範囲で多様な変更および変形が可能なことは理解できるであろう。したがって、本発明の範囲は、説明された実施形態によって定められず、特許請求の範囲に記載された技術的趣旨により定められねばならない。   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.
