国際公開第２０１４／１０２９０５号International Publication No. 2014/102905 米国特許第７５０６４１９号明細書US Pat. No. 7,506,419

雄部材の軸状突起のための出入口を有する収容部材と、収容部材内に配置され、出入口を介して収容部材外に向かう軸状突起を制止可能である制止具を含む雌部材が用いられる場合、雌部材の厚みが増加してしまう傾向がある。収容部材は、制止具の収容空間を画定する上壁と下壁を含み、また、ある程度の制止具の厚みも確保することが要求されるためである。特許文献１では、この点に鑑みて、収容部材の上壁に軸状突起の頭部の受容凹部を形成する。しかしながら、受容凹部に対応するドーム部が収容部材の上壁の上面に形成され、雌部材の外観に影響を与えてしまうため、このようなドーム部を無くし、若しくはその隆起の程度を低減することが望まれる場合がある。 When a housing member having an entrance / exit for an axial projection of a male member and a female member including a restraining tool that is disposed in the accommodation member and is capable of restraining the axial projection going out of the accommodation member through the entrance / exit The thickness of the female member tends to increase. This is because the housing member includes an upper wall and a lower wall that define a housing space for the restraining device, and a certain degree of thickness of the restraining device is required. In Patent Document 1, in view of this point, a receiving concave portion of the head portion of the axial protrusion is formed on the upper wall of the housing member. However, since the dome corresponding to the receiving recess is formed on the upper surface of the upper wall of the housing member and affects the appearance of the female member, such a dome is eliminated or the extent of the bulge is reduced. May be desired.

図１乃至図１１に示す非限定の一実施形態例のバックル１００は、雄部材５０上に雌部材７０を重ねて両者を係合又は連結する重ね合わせ型又は積層型バックルである。雄部材５０及び雌部材７０は、各々、１以上の樹脂パーツから構成される。別例においては、雄部材５０及び雌部材７０は、各々、樹脂パーツと金属パーツから構成される。用いられる樹脂は、例えば、ポリアセタール、ポリアミド、ポリプロピレン等の剛性樹脂である。樹脂パーツや金属パーツは、射出成形により製造可能である。 The buckle 100 of one non-limiting embodiment shown in FIGS. 1 to 11 is a stacked or stacked buckle in which a female member 70 is stacked on a male member 50 to engage or connect them. The male member 50 and the female member 70 are each composed of one or more resin parts. In another example, the male member 50 and the female member 70 are each comprised of a resin part and a metal part. The resin used is, for example, a rigid resin such as polyacetal, polyamide, or polypropylene. Resin parts and metal parts can be manufactured by injection molding.

雄部材５０は、少なくとも首部５３と首部５３に比して幅広の頭部５４を有する少なくとも一つの軸状突起５２が設けられた基部５１を備える。雄部材５０の基部５１は、必ずしもこの限りではないが、本開示の全図示例で示す如く平板部である。この平板状の基部５１は、図３に端的に示す如く、軸状突起５２が設けられる第１平板部５１ｆと、ベルト巻付棹５１ｈが設けられ、第１平板部５１ｆよりも幅広である第２平板部５１ｇを有する。雌部材７０と雄部材５０が係合又は連結する時、雌部材７０は、雄部材５０の基部５１の第１平板部５１ｆ上に載置され、第１平板部５１ｆ上で軸状突起５２の周りを回転可能である。なお、雄部材５０上で雌部材７０を回転不能とし、又はその回転可能範囲を制限する形態も想定される。 The male member 50 includes a base portion 51 provided with at least one axial protrusion 52 having at least a neck portion 53 and a head portion 54 wider than the neck portion 53. The base 51 of the male member 50 is not necessarily limited to this, but is a flat plate as shown in all illustrated examples of the present disclosure. As shown straight in FIG. 3, the flat base 51 is provided with a first flat plate portion 51f provided with a shaft-like protrusion 52 and a belt winding rod 51h, and is wider than the first flat plate portion 51f. It has 2 flat plate parts 51g. When the female member 70 and the male member 50 are engaged or connected, the female member 70 is placed on the first flat plate portion 51f of the base portion 51 of the male member 50, and the axial projection 52 is formed on the first flat plate portion 51f.

The head portion 54 and the neck portion 53 are smaller than the opening diameter of the entrance / exit 80 k of the housing member 80.

本明細書においては、専ら説明の便宜のため、上下方向が、軸状突起５２の延在方向に一致するものとして参照される。当業者は、上下方向が便宜的なものであり、必ずしも鉛直方向に一致するものではないことを極自然に理解する。 In the present specification, for convenience of explanation, the vertical direction is referred to as the direction in which the axial protrusion 52 extends. Those skilled in the art will naturally understand that the vertical direction is convenient and does not necessarily coincide with the vertical direction.

図７（ｂ）に示すように、頭部５４は、首部５３の外周面５３Ｆとの関係で段差を形成する環状下面５４Ｎと、環状下面５４Ｎから上方に向かうに応じて緩慢に縮径する傘部５４Ｍを含む。傘部５４Ｍの外周面は緩慢な曲面であり、幾つかの場合、傘部５４Ｍの頂面には平坦面が含まれる。なお、軸状台座部５５も、首部５３の外周面５３Ｆとの関係で段差を形成する環状上面５５Ｍと、首部５３の外周面５３Ｆよりも半径方向外側に位置する外周面５５Ｎを有する。後述の説明から理解されるように、軸状台座部５５の環状上面５５Ｍは、後述の雌部材７０の制止具９０が載置可能な載置面である。後述の可動部９３の係合部９６の薄肉部９６ｎの障壁部９５は、軸状突起５２の頭部５４の環状下面５４Ｎと、軸状台座部５５の環状上面５５Ｍの間に配置可能である。なお、環状下面５４Ｎと環状上面５５Ｍは、上下方向において首部５３分の間隔を空けて対面する。 As shown in FIG. 7B, the head 54 includes an annular lower surface 54N that forms a step in relation to the outer peripheral surface 53F of the neck 53, and an umbrella that gradually decreases in diameter as it goes upward from the annular lower surface 54N. Part 54M. The outer peripheral surface of the umbrella portion 54M is a slow curved surface, and in some cases, the top surface of the umbrella portion 54M includes a flat surface. The shaft-like pedestal portion 55 also has an annular upper surface 55M that forms a step in relation to the outer peripheral surface 53F of the neck portion 53, and an outer peripheral surface 55N that is positioned radially outward from the outer peripheral surface 53F of the neck portion 53. As will be understood from the description below, the annular upper surface 55M of the shaft-shaped pedestal portion 55 is a mounting surface on which a restraining device 90 of the female member 70 described later can be mounted. The barrier portion 95 of the thin portion 96n of the engaging portion 96 of the movable portion 93 described later can be disposed between the annular lower surface 54N of the head portion 54 of the shaft-like protrusion 52 and the annular upper surface 55M of the shaft-like pedestal portion 55. . The annular lower surface 54N and the annular upper surface 55M face each other with an interval of the neck portion 53 in the vertical direction.

雌部材７０は、軸状突起５２のための出入口８０ｋを有する収容部材８０と、少なくとも部分的に収容部材８０内に配されると共に、出入口８０ｋを介して収容部材８０外に向かう軸状突起５２を制止可能である制止具９０を備える。 The female member 70 has an accommodating member 80 having an entrance / exit 80k for the axial projection 52, and an axial projection 52 that is at least partially disposed in the accommodating member 80 and goes out of the accommodating member 80 via the entrance / exit 80k. It is provided with a restraining device 90 capable of restraining.

図１、図２、及び図４、特に図４に示すように、収容部材８０は、出入口８０ｋに空間連通した制止具９０の収容用の収容空間８０ｊが設けられた箱部８０ｆと、ベルト巻付棹８２が設けられた枠部８０ｇを有する。図４に示すように、収容部材８０の箱部８０ｆは、収容空間８０ｊを画定する壁部として、上壁８０ａ、下壁８０ｂ、第１横壁８０ｃ、及び第２横壁８０ｄを含む。 As shown in FIGS. 1, 2, and 4, particularly FIG. 4, the housing member 80 includes a box portion 80 f provided with a housing space 80 j for housing the stopper 90 that communicates with the entrance 80 k, and a belt winding. It has a frame portion 80g provided with a hook 82. As shown in FIG. 4, the box part 80f of the accommodation member 80 includes an upper wall 80a, a lower wall 80b, a first lateral wall 80c, and a second lateral wall 80d as wall parts that define the accommodation space 80j.

上壁８０ａには、一対の案内溝８０ｐ、８０ｑが設けられ、後述の制止具９０の案内凸部９８ｐ、９８ｑと嵌合し、制止具９０の挿入及び制止具９０の操作部９１の変位が案内される。下壁８０ｂには、上述の出入口８０ｋが設けられる。出入口８０ｋと第１横壁８０ｃの間で下壁８０ｂに設けられた開口８０ｕ２は、特殊な治具により収容部材８０と制止具９０の係合を解除することを可能にするためのものである。出入口８０ｋと第２横壁８０ｄの間で下壁８０ｂに設けられた開口８０ｕ１も同様である。なお、案内溝８０ｐ、８０ｑは、ベルト巻付棹８２の延在方向に略平行に延びる。案内溝８０ｐ、８０ｑの延在方向は、収容部材８０に対する制止具９０の挿入方向に合致し、また収容部材８０内に挿入及び保持された制止具９０の操作部９１の操作方向に合致する。 The upper wall 80a is provided with a pair of guide grooves 80p and 80q, which are fitted with guide convex portions 98p and 98q of a later-described restraining device 90, so that the insertion of the restraining device 90 and the displacement of the operation portion 91 of the restraining device 90 are performed. Guided. The lower wall 80b is provided with the aforementioned entrance / exit 80k. An opening 80u2 provided in the lower wall 80b between the entrance / exit 80k and the first lateral wall 80c is for enabling the engagement between the housing member 80 and the restraining device 90 to be released by a special jig. The same applies to the opening 80u1 provided in the lower wall 80b between the entrance 80k and the second lateral wall 80d. The guide grooves 80p, 80q extend substantially parallel to the extending direction of the belt winding rod 82. The extending directions of the guide grooves 80p and 80q coincide with the insertion direction of the restraining device 90 with respect to the housing member 80, and also coincide with the operation direction of the operation portion 91 of the restraining device 90 inserted and held in the housing member 80.

図２から理解できるように、収容部材８０の箱部８０ｆには、制止具９０の挿入を許容する一対の開口８０ｒが設けられる。制止具９０が収容部材８０内に挿入及び保持される時、各開口８０ｒが、後述の制止具９０の各操作部９１により閉じられる。換言すれば、制止具９０の各操作部９１が収容部材８０の各開口８０ｒから外側に突出する。バックル１００のユーザーは、この収容部材８０の開口８０ｒから外側に突出した操作部９１を内側に押し込むことにより制止具９０を解放状態とすることができる。制止具９０が解放状態の時、雄部材５０から雌部材７０を引き離し、両者を非係合状態にすることができる。必ずしもこの限りではないが、本図示例の各開口８０ｒは、上壁８０ａ、下壁８０ｂ、第１横壁８０ｃ、及び第２横壁８０ｄにより画定される。 As can be understood from FIG. 2, the box portion 80 f of the housing member 80 is provided with a pair of openings 80 r that allow the stopper 90 to be inserted. When the stop 90 is inserted and held in the housing member 80, each opening 80r is closed by each operation portion 91 of the stop 90 described later. In other words, each operation portion 91 of the restraining tool 90 protrudes outward from each opening 80 r of the housing member 80. The user of the buckle 100 can release the stopper 90 by pushing the operating portion 91 protruding outward from the opening 80r of the housing member 80 inward. When the restraining device 90 is in the released state, the female member 70 can be pulled away from the male member 50, and both can be brought into a disengaged state. Although not necessarily limited thereto, each opening 80r in the illustrated example is defined by an upper wall 80a, a lower wall 80b, a first lateral wall 80c, and a second lateral wall 80d.

以下、説明の便宜上、図９のように雄部材５０と雌部材７０が係合又は連結した状態を前提又は想定しつつ、上下方向に直交する平面において軸状突起５２から離間する方向を外側とし、軸状突起５２に向かう方向を内側と呼ぶ。軸状突起５２は、異なる上下高さにおいて異なる径を有する円柱部分である。従って、以下、内側及び外側に関して径方向内側及び径方向外側とのより具体的な用語が用いられる。 Hereinafter, for convenience of explanation, assuming that the male member 50 and the female member 70 are engaged or connected as shown in FIG. 9, the direction away from the axial protrusion 52 in the plane orthogonal to the vertical direction is defined as the outside. The direction toward the axial protrusion 52 is referred to as the inner side. The axial protrusion 52 is a cylindrical portion having different diameters at different vertical heights. Therefore, hereinafter, more specific terms of the radially inner side and the radially outer side are used with respect to the inner side and the outer side.

制止具９０は、収容部材８０の開口８０ｒを介して収容部材８０外に突出する操作部９１と、外力を受けて弾性的に変形可能なバネ部９２と、弾性変形したバネ部９２が元形状に復帰するに際して、頭部５４の通過を許す解放位置から頭部５４の通過を許さない制止位置に変位可能である可動部９３を有する。図２では、一対の操作部９１が、符号９１Ｍ、９１Ｎにより区別されている。一対のバネ部９２が、符号９２Ｍ、９２Ｎにより区別されている。各バネ部９２は、後述の各可動部９３の連結部９７により２分割され、若しくは２区間に区分されているように見える。 The restraining device 90 has an operating portion 91 that protrudes outside the housing member 80 through the opening 80r of the housing member 80, a spring portion 92 that can be elastically deformed by receiving an external force, and a spring portion 92 that is elastically deformed. When returning to, the movable portion 93 is displaceable from a release position that allows passage of the head 54 to a stop position that does not allow passage of the head 54. In FIG. 2, the pair of operation units 91 are distinguished by reference numerals 91M and 91N. The pair of spring portions 92 are distinguished by reference numerals 92M and 92N. Each spring portion 92 appears to be divided into two or divided into two sections by a connecting portion 97 of each movable portion 93 described later.

図２及び図５の図示例に係る制止具９０は、一対の操作部９１と、一対のバネ部９２、及び一対の可動部９３を有する。各バネ部９２は、一対の操作部９１の間を弧状に延び、その中央部において可動部９３に連結する。バネ部９２の一端が一方の操作部９１に連結し、バネ部９２の他端が他方の操作部９１に連結する。図９に示す雄部材５０と雌部材７０の係合又は連結状態では、バネ部９２は、軸状突起５２の周方向に沿って延びる。 2 and FIG. 5 includes a pair of operation portions 91, a pair of spring portions 92, and a pair of movable portions 93. Each spring portion 92 extends in an arc shape between the pair of operation portions 91 and is connected to the movable portion 93 at the center portion thereof. One end of the spring portion 92 is connected to one operation portion 91, and the other end of the spring portion 92 is connected to the other operation portion 91. In the engaged or connected state of the male member 50 and the female member 70 shown in FIG. 9, the spring portion 92 extends along the circumferential direction of the axial protrusion 52.

各可動部９３は、上述のようにバネ部９２の撓みの程度に応じて上述の解放位置と制止位置を取ることができる。解放位置では、可動部９３は、制止位置と比較して径方向外側に位置する。制止位置では、可動部９３は、解放位置と比較して径方向内側に位置する。図示例の可動部９３は、バネ部９２に連結する連結部９７と、連結部９７を介してバネ部９２に連結する係合部９６を有する。連結部９７は、バネ部９２の中央部に連結するが、必ずしもこの限りではない。連結部９７は、バネ部９２よりも大きい厚みを有するが、必ずしもこの限りではない。なお、連結部９７をバネ部９２よりも膨大とすることでバネ部９２から係合部９６への力の円滑な伝達が確保できる。係合部９６は、出入口８０ｋを介して収容部材８０外に向かう軸状突起５２を制止する部分である。係合部９６は、軸状突起５２の周方向に半円を描くように延びる弧状部分であるが、必ずしもこの限りではない。 Each movable part 93 can take the above-mentioned release position and stop position according to the degree of bending of the spring part 92 as described above. In the release position, the movable portion 93 is located on the radially outer side compared to the stop position. In the stop position, the movable part 93 is located radially inward compared to the release position. The movable portion 93 in the illustrated example has a connecting portion 97 connected to the spring portion 92 and an engaging portion 96 connected to the spring portion 92 via the connecting portion 97. The connecting portion 97 is connected to the central portion of the spring portion 92, but this is not necessarily the case. The connecting portion 97 has a thickness larger than that of the spring portion 92, but is not necessarily limited thereto. In addition, smooth transmission of the force from the spring part 92 to the engaging part 96 can be ensured by making the connecting part 97 larger than the spring part 92. The engaging portion 96 is a portion that restrains the axial protrusion 52 that goes out of the housing member 80 through the doorway 80k. The engaging portion 96 is an arc-shaped portion extending so as to draw a semicircle in the circumferential direction of the axial protrusion 52, but is not necessarily limited thereto.

係合部９６は、連結部９７よりも厚みが薄い薄肉部９６ｎを含む。図示例では、係合部９６は、径方向内側の薄肉部９６ｎと、径方向外側の厚肉部９６ｍを含む。厚肉部９６ｍは、薄肉部９６ｎよりも上下方向における厚みが大きい。厚肉部９６ｍは、薄肉部９６ｎと連結部９７の間に設けられる。図８の参照から理解できるように、収容部材８０内に制止具９０が挿入及び保持される時、厚肉部９６ｍは、収容部材８０の上壁８０ａと下壁８０ｂの間で緩く挟まれる。薄肉部９６ｎは、収容部材８０の下壁８０ｂの出入口８０ｋを規定する開口縁よりも径方向内側に突出する。薄肉部９６ｎは、軸状突起５２の頭部５４と軸状台座部５５の間で首部５３の外周に隣接配置又は接触する障壁部９５を有する。障壁部９５の上下方向における厚みは、軸状突起５２の首部５３の上下方向における寸法と略同じである。 The engaging portion 96 includes a thin portion 96 n that is thinner than the connecting portion 97. In the illustrated example, the engagement portion 96 includes a radially inner thin portion 96n and a radially outer thick portion 96m. The thick part 96m is thicker in the vertical direction than the thin part 96n. The thick part 96m is provided between the thin part 96n and the connecting part 97. As can be understood from the reference to FIG. 8, when the stopper 90 is inserted and held in the housing member 80, the thick portion 96 m is loosely sandwiched between the upper wall 80 a and the lower wall 80 b of the housing member 80. The thin portion 96n protrudes radially inward from the opening edge that defines the entrance / exit 80k of the lower wall 80b of the housing member 80. The thin-walled portion 96n includes a barrier portion 95 that is disposed adjacent to or in contact with the outer periphery of the neck portion 53 between the head portion 54 of the shaft-shaped protrusion 52 and the shaft-shaped pedestal portion 55. The thickness in the vertical direction of the barrier portion 95 is substantially the same as the vertical dimension of the neck portion 53 of the axial protrusion 52.

図９に示す雄部材５０と雌部材７０の係合又は連結状態では、各バネ部９２は、弱く撓んだ状態にあり、各係合部９６が径方向内側に付勢される。若しくは、各バネ部９２は、全く撓んでいなく、各係合部９６が径方向内側に付勢されない。雄部材５０の軸状突起５２は、一対の係合部９６により挟み込まれる。出入口８０ｋを介して収容部材８０外に向かう方向の軸状突起５２の変位が、各係合部９６の薄肉部９６ｎの障壁部９５により制止される。雄部材５０から雌部材７０を上方に引き離そうとしても、各係合部９６の薄肉部９６ｎの障壁部９５の上面が、軸状突起５２の頭部５４の環状下面５４Ｎに衝突する。換言すれば、出入口８０ｋを介して収容部材８０の外側に軸状突起５２が抜け出ることが、制止具９０により、より端的には頭部５４と軸状台座部５５の間の障壁部９５により阻止される。制止具９０は、収容部材８０の上壁８０ａと下壁８０ｂの間で保持されており、軸状突起５２の頭部５４から受ける力に十分に対抗することができる。なお、図９に示す状態では、一対の係合部９６の障壁部９５の間隔は、頭部５４の通過を許容するものではない。 In the engaged or connected state of the male member 50 and the female member 70 shown in FIG. 9, each spring portion 92 is weakly bent and each engaging portion 96 is urged radially inward. Alternatively, each spring portion 92 is not bent at all, and each engagement portion 96 is not biased radially inward. The axial projection 52 of the male member 50 is sandwiched between a pair of engaging portions 96. The displacement of the axial protrusion 52 in the direction toward the outside of the housing member 80 through the doorway 80k is restrained by the barrier portion 95 of the thin portion 96n of each engaging portion 96. Even if the female member 70 is pulled upward from the male member 50, the upper surface of the barrier portion 95 of the thin portion 96n of each engaging portion 96 collides with the annular lower surface 54N of the head portion 54 of the shaft-like protrusion 52. In other words, the shaft-like protrusion 52 is prevented from coming out of the housing member 80 through the doorway 80k by the stopper 90, more specifically, by the barrier portion 95 between the head 54 and the shaft-like pedestal portion 55. Is done. The restraining device 90 is held between the upper wall 80 a and the lower wall 80 b of the housing member 80, and can sufficiently resist the force received from the head 54 of the shaft-like protrusion 52. In the state shown in FIG. 9, the distance between the barrier portions 95 of the pair of engaging portions 96 does not allow the head portion 54 to pass.

図１０に示す雄部材５０と雌部材７０の非係合状態では、各バネ部９２は、外力、必ずしもこの限りではないが、図示例の場合、操作部９１から伝達する外力に応じて大きく撓んでいる。一対の操作部９１の間を弧状に延びていたバネ部９２は、外力に応じて、一対の操作部９１の間で大きな起伏を描くように変形し、バネ部９２のうち最も径方向外側に位置する中央部が、径方向外側に大きく変位する。バネ部９２の中央部に連結した可動部９３も径方向外側に大きく変位する。端的には、可動部９３は、制止位置から解放位置に変位する。可動部９３が解放位置に変位した状態において、一対の可動部９３の間隔、端的には、障壁部９５の間隔は、雄部材５０の軸状突起５２の頭部５４の直径よりも大きくなり、頭部５４の通過を許容する。 In the non-engaged state of the male member 50 and the female member 70 shown in FIG. 10, each spring portion 92 is not necessarily limited to an external force, but in the illustrated example, the spring portion 92 is greatly bent according to the external force transmitted from the operation portion 91. It is. The spring portion 92 extending in an arc shape between the pair of operation portions 91 is deformed so as to draw a large undulation between the pair of operation portions 91 according to the external force, and is most radially outward of the spring portions 92. The central part is greatly displaced radially outward. The movable part 93 connected to the central part of the spring part 92 is also greatly displaced radially outward. In short, the movable portion 93 is displaced from the stop position to the release position. In a state where the movable part 93 is displaced to the release position, the distance between the pair of movable parts 93, that is, the distance between the barrier parts 95 is larger than the diameter of the head part 54 of the axial protrusion 52 of the male member 50. The passage of the head 54 is allowed.

可動部９３が制止位置から解放位置に変位する時、連結部９７の径方向外側端部が、各々、収容部材８０の第１及び第２横壁８０ｃ、８０ｄに設けられた位置決め凹部８１ｇに嵌合する。これにより、操作部９１の変位及びバネ部９２の撓みに連動した可動部９３の変位の安定性が高められる。なお、図示例の連結部９７の径方向外側端部は、位置決め凹部８１ｇとの嵌合に適するように径方向外側に向けて先細りに構成される。なお、上述のとおり、制止具９０の操作部９１の変位は、収容部材８０の上壁８０ａの各案内溝８０ｐ、８０ｑと、制止具９０の各案内凸部９８ｐ、９８ｑの嵌合により安定化されている。 When the movable portion 93 is displaced from the stop position to the release position, the radially outer ends of the connecting portion 97 are fitted into the positioning recesses 81g provided in the first and second lateral walls 80c and 80d of the housing member 80, respectively. To do. Thereby, the stability of the displacement of the movable part 93 interlocked with the displacement of the operation part 91 and the bending of the spring part 92 is improved. In addition, the radial direction outer side edge part of the connection part 97 of an example of illustration is tapered toward the radial direction outer side so that it may be suitable for fitting with the positioning recessed part 81g. As described above, the displacement of the operation portion 91 of the restraining device 90 is stabilized by fitting the guide grooves 80p and 80q of the upper wall 80a of the housing member 80 with the guide convex portions 98p and 98q of the restraining device 90. Has been.

制止具９０及び収容部材８０は、制止具９０が収容部材８０に一度挿入されると、収容部材８０から制止具９０が抜け出ないように構成される。図９に示す時、操作部９１の各脚９１ｆの先端突起９１ｇが収容部材８０の各係止突起８１ｆにより係止され、収容部材８０から制止具９０が抜け出すことが抑制される。図１０に示す時、収容部材８０の開口８０ｒから突出する操作部９１が収容部材８０内に押され、先端突起９１ｇと係止突起８１ｆの係合が解除される。しかしながら、操作部９１の押圧が解除されれば、バネ部９２が元形状に復帰し、操作部９１及び先端突起９１ｇが元の位置に復帰し、先端突起９１ｇと係止突起８１ｆが元の係合状態に戻る。先端突起９１ｇや係止突起８１ｆの位置、大きさ、個数は、当業者により適切に変更可能である。 The restraining device 90 and the housing member 80 are configured so that the restraining device 90 does not come out of the housing member 80 once the restraining device 90 is inserted into the housing member 80. 9, the tip protrusions 91g of the legs 91f of the operation portion 91 are locked by the locking protrusions 81f of the storage member 80, and the restraining device 90 is prevented from coming out of the storage member 80. As shown in FIG. 10, the operating portion 91 protruding from the opening 80r of the housing member 80 is pushed into the housing member 80, and the engagement between the tip projection 91g and the locking projection 81f is released. However, when the pressing of the operation portion 91 is released, the spring portion 92 returns to the original shape, the operation portion 91 and the tip projection 91g return to their original positions, and the tip projection 91g and the locking projection 81f return to the original engagement. Return to the match state. The position, size, and number of the tip protrusions 91g and the locking protrusions 81f can be appropriately changed by those skilled in the art.

本実施形態においては、可動部９３は、上述の解放位置から制止位置に向かう方向にて薄肉化された薄肉部９６ｎを有する。換言すれば、係合部９６は、上述の解放位置から制止位置に向かう方向にて薄肉化された薄肉部９６ｎを有する。なお、薄肉化は、上下方向の厚みの減少を意味する。端的には、薄肉部９６ｎの厚みは、連結部９７の厚みよりも小さい。必ずしもこの限りではないが、図示例では、可動部９３は、連結部９７と薄肉部９６ｎの間に厚肉部９６ｍを有し、薄肉部９６ｎの厚みは、厚肉部９６ｍの厚みよりも小さい。制止具９０により制止された状態の軸状突起５２の頭部５４が薄肉部９６ｎ上に配置されることが許容される。これにより、収容部材８０の上壁８０ａに頭部５４用の受容凹部を設ける必要がなく、上壁８０ａの上面のドーム部を無くし、又はその隆起の程度を低減することができる。 In the present embodiment, the movable portion 93 includes a thin portion 96n that is thinned in the direction from the release position to the stop position. In other words, the engagement portion 96 has a thin portion 96n that is thinned in the direction from the release position to the stop position. Note that thinning means a reduction in thickness in the vertical direction. In short, the thickness of the thin portion 96n is smaller than the thickness of the connecting portion 97. Although not necessarily limited to this, in the illustrated example, the movable portion 93 has a thick portion 96m between the connecting portion 97 and the thin portion 96n, and the thickness of the thin portion 96n is smaller than the thickness of the thick portion 96m. . It is allowed that the head portion 54 of the shaft-like protrusion 52 in a state of being restrained by the restraining tool 90 is disposed on the thin portion 96n. Thereby, there is no need to provide a receiving recess for the head 54 in the upper wall 80a of the housing member 80, and the dome portion on the upper surface of the upper wall 80a can be eliminated or the degree of the bulge can be reduced.

図８の図示例の薄肉部９６ｎは、弧状の係合部９６の径方向内側、端的にはその径方向内端部に段差を生じさせ、薄肉部９６ｎ上に頭部５４を配置可能とする。図８に示す場合、収容部材８０、特にはその上壁８０ａは、制止具９０により制止された軸状突起５２の頭部５４に対面する略平坦な内面領域を含む。幾つかの場合、薄肉部９６ｎ及び／又は頭部５４は、軸状突起５２が制止具９０により制止される時、頭部５４が厚肉部９６ｍの上面から実質的に突出しないように構成される。
換言すれば、厚肉部９６ｍの上面と薄肉部９６ｎの上面との上下間隔ｔ１（図６（ｂ）参照）は、軸状突起５２の頭部５４の上下寸法ｔ２（図７（ｂ）参照）以上または同一に形成される。これにより、頭部５４が、厚肉部９６ｍの上面と薄肉部９６ｎの上面との間に収容される。この際、頭部５４の上面と、上壁８０ａの内面領域との間には間隔が形成され、互いに接触しない。なお、厚肉部９６ｍの上面は、厚肉部９６ｍの主面の一つである。 The thin-walled portion 96n in the illustrated example of FIG. 8 generates a step at the radially inner side of the arc-shaped engaging portion 96, and finally at the radially inner end thereof, so that the head 54 can be disposed on the thin-walled portion 96n. . In the case shown in FIG. 8, the housing member 80, particularly the upper wall 80 a thereof, includes a substantially flat inner surface area facing the head 54 of the shaft-like protrusion 52 restrained by the restraining tool 90. In some cases, the thin portion 96n and / or the head portion 54 are configured such that the head portion 54 does not substantially protrude from the upper surface of the thick portion 96m when the axial protrusion 52 is restrained by the restraining device 90. The
In other words, the vertical interval t1 (see FIG. 6B) between the upper surface of the thick portion 96m and the upper surface of the thin portion 96n is the vertical dimension t2 of the head 54 of the axial protrusion 52 (see FIG. 7B). ) Or more or the same. Thereby, the head 54 is accommodated between the upper surface of the thick part 96m and the upper surface of the thin part 96n. At this time, an interval is formed between the upper surface of the head 54 and the inner surface region of the upper wall 80a, and they do not contact each other. The upper surface of the thick portion 96m is one of the main surfaces of the thick portion 96m.

雄部材５０と雌部材７０が係合する過程について説明する。雌部材７０の各操作部９１が収容部材８０の内側に向けて押され、各バネ部９２が大きく撓み、各可動部９３及び係合部９６が制止位置から解放位置に変位する。この状態の雌部材７０を雄部材５０上に重ね合わせると、雄部材５０の軸状突起５２が、雌部材７０の収容部材８０の出入口８０ｋを介して収容部材８０内に突入する。詳細には、軸状突起５２の頭部５４が、収容部材８０の出入口８０ｋを通過し、続いて、制止具９０の一対の係合部９６の間の空間を通過する。 A process in which the male member 50 and the female member 70 are engaged will be described. Each operation portion 91 of the female member 70 is pushed toward the inside of the housing member 80, each spring portion 92 is greatly bent, and each movable portion 93 and the engagement portion 96 are displaced from the stop position to the release position. When the female member 70 in this state is overlaid on the male member 50, the shaft-like protrusion 52 of the male member 50 enters the housing member 80 via the entrance / exit 80 k of the housing member 80 of the female member 70. Specifically, the head portion 54 of the axial protrusion 52 passes through the entrance / exit 80 k of the housing member 80, and then passes through the space between the pair of engaging portions 96 of the stopper 90.

雌部材７０が雄部材５０上に重ね合わされると、雌部材７０の各操作部９１の押圧が解除される。すると、バネ部９２が元の形状に復帰するように働き、操作部９１及び可動部９３及び弧状部９６が元の位置に向けて付勢される。操作部９１は、開口８０ｒを介して収容部材８０の外側に突出するまで移動する。可動部９３は、解放位置から制止位置に復帰するまで移動する。可動部９３が制止位置に完全に復帰すると、軸状突起５２の首部５３が一対の係合部９６により挟み込まれる。各係合部９６の薄肉部９６ｎの障壁部９５が、軸状突起５２の頭部５４と軸状台座部５５の間に挿入され、軸状突起５２の上下変位が規制される。幾つかの場合、障壁部９５は、首部５３の外周面５３Ｆに直に接触する。別の場合は、障壁部９５は、首部５３の外周面５３Ｆに直に接触しない。雄部材５０と雌部材７０の係合が解除される過程については、上述の説明から理解可能であり、詳細な説明は省略する。 When the female member 70 is superimposed on the male member 50, the pressing of each operation portion 91 of the female member 70 is released. Then, the spring portion 92 works to return to the original shape, and the operation portion 91, the movable portion 93, and the arc-shaped portion 96 are urged toward the original position. The operation unit 91 moves until it protrudes outside the housing member 80 through the opening 80r. The movable part 93 moves from the release position to the stop position. When the movable portion 93 is completely returned to the stop position, the neck portion 53 of the shaft-like protrusion 52 is sandwiched between the pair of engaging portions 96. The barrier portion 95 of the thin portion 96n of each engaging portion 96 is inserted between the head portion 54 of the shaft-like protrusion 52 and the shaft-like pedestal portion 55, and the vertical displacement of the shaft-like protrusion 52 is restricted. In some cases, the barrier portion 95 directly contacts the outer peripheral surface 53F of the neck portion 53. In another case, the barrier portion 95 does not directly contact the outer peripheral surface 53F of the neck portion 53. The process of releasing the engagement between the male member 50 and the female member 70 can be understood from the above description, and the detailed description is omitted.

なお、図１１に示すように、雄部材５０と雌部材７０が係合又は連結状態の時、雌部材７０は、雄部材５０に対して回転可能である。同様に、雄部材５０は、雌部材７０に対して回転可能である。雄部材５０のベルト巻付棹５１ｈと、雌部材７０のベルト巻付棹８２の相対位置を軸状突起５２の周方向において変更可能である。 As shown in FIG. 11, when the male member 50 and the female member 70 are engaged or connected, the female member 70 is rotatable with respect to the male member 50. Similarly, the male member 50 is rotatable with respect to the female member 70. The relative positions of the belt winding rod 51 h of the male member 50 and the belt winding rod 82 of the female member 70 can be changed in the circumferential direction of the axial protrusion 52.

図６から良く理解できるように、解放位置から制止位置に向かう方向、つまり径方向における薄肉部９６ｎの長さは、軸状突起５２を周囲する周方向において変化する。つまり、薄肉部９６ｎの径方向長さは、軸状突起５２を周囲する周方向における薄肉部９６ｎの各端部の間の中間部が、各端部に比べて相対的に大きい。端的には、軸状突起５２を周囲する周方向における薄肉部９６ｎの各端部における径方向長さは、軸状突起５２を周囲する周方向における薄肉部９６ｎの各端部の間の中間部における径方向長さよりも短い。かかる構成により、周方向沿いの薄肉部９６ｎの中央部をより径方向内側に配することが許され、増加した径方向長さの障壁部９５により頭部５４のより十分な制止が達成される。 As can be clearly understood from FIG. 6, the length of the thin portion 96 n in the direction from the release position to the stop position, that is, in the radial direction, changes in the circumferential direction around the axial protrusion 52. That is, the radial length of the thin portion 96n is relatively larger at the intermediate portion between the end portions of the thin portion 96n in the circumferential direction around the axial protrusion 52 than at each end portion. In short, the radial length at each end of the thin portion 96n in the circumferential direction surrounding the axial protrusion 52 is an intermediate portion between the end portions of the thin portion 96n in the circumferential direction surrounding the axial protrusion 52. Shorter than the length in the radial direction. With such a configuration, the central portion of the thin wall portion 96n along the circumferential direction is allowed to be arranged on the radially inner side, and the barrier portion 95 having an increased radial length can achieve more sufficient restraining of the head portion 54. .

図１乃至図１１の図示例では、収容部材８０の上面は平坦面である。しかしながら、図１２に示す別例では、収容部材８０の上面にはＸ字状の隆起部５１０が設けられる。なお、収容部材８０の上壁８０ａには頭部５４用の受容凹部が設けられていない。従って、上壁８０ａの上面の隆起部５１０の隆起の程度が低減可能である。そのため、上壁８０ａの上面の形状は受容凹部の影響を受けることがなく、Ｘ字状の隆起部５１０を形成することや、ロゴ・マークなどの装飾を付加することが容易となる。なお、図１２に示す例には、隆起部５１０が設けられる点を除いて図１乃至図１１の例と同様の説明が当てはまる。 In the illustrated examples of FIGS. 1 to 11, the upper surface of the housing member 80 is a flat surface. However, in another example shown in FIG. 12, an X-shaped raised portion 510 is provided on the upper surface of the housing member 80. The upper wall 80a of the housing member 80 is not provided with a receiving recess for the head 54. Therefore, the degree of the bulging of the bulging portion 510 on the upper surface of the upper wall 80a can be reduced. Therefore, the shape of the upper surface of the upper wall 80a is not affected by the receiving recess, and it becomes easy to form the X-shaped raised portion 510 and to add a decoration such as a logo mark. The example illustrated in FIG. 12 is the same as the example of FIGS. 1 to 11 except that the raised portion 510 is provided.

図１３乃至図１５の図示例では、図１乃至図１１の例と比較して、一方の操作部９１が被係止棹５２０に置換される。また、制止具９０は、収容部材８０の一つの開口８０ｒを介して収容部材８０内に挿入される。このような場合においても、上述の説明が同様に当てはまる。 In the illustrated examples of FIGS. 13 to 15, one operation portion 91 is replaced with a locked bar 520 as compared with the examples of FIGS. 1 to 11. Further, the stopper 90 is inserted into the housing member 80 through one opening 80 r of the housing member 80. Even in such a case, the above description applies similarly.

図１５から端的に理解されるように、被係止棹５２０は、収容部材８０の一対の係止突起８１ｆにより係止され、一度、収容部材８０内に入った後、収容部材８０から出ることが阻止される。収容部材８０の箱部８０ｆに設けられる開口８０ｒは、枠部８０ｇの反対側に位置する。制止具９０は、開口８０ｒを介して枠部８０ｇに向かって挿入される。収容部材８０の各係止突起８１ｆは、被係止棹５２０の各端部が乗り越え可能なように緩慢な傾斜面８１ｆ１を有する。被係止棹５２０は、傾斜面８１ｆ１を乗り越えた後、係止突起８１ｆにより係止される。上述の係止突起８１ｆの乗り越えのため、被係止棹５２０の各端部が径方向内側に僅かに反らされている。収容部材８０は、上壁８０ａと下壁８０ｂを接続する第３及び第４横壁８０ｅ１、８０ｅ２を有する。第３及び第４横壁８０ｅ１、８０ｅ２それぞれに位置決め凹部８１ｇが設けられる。 As can be understood from FIG. 15, the locked bar 520 is locked by the pair of locking protrusions 81 f of the storage member 80, and once enters the storage member 80, it comes out of the storage member 80. Is blocked. The opening 80r provided in the box part 80f of the housing member 80 is located on the opposite side of the frame part 80g. The restraining tool 90 is inserted toward the frame portion 80g through the opening 80r. Each locking projection 81f of the housing member 80 has a slanted inclined surface 81f1 so that each end of the locked rod 520 can get over. The locked bar 520 is locked by the locking protrusion 81f after getting over the inclined surface 81f1. In order to get over the above-described locking projection 81f, each end of the locked rod 520 is slightly warped radially inward. The housing member 80 includes third and fourth lateral walls 80e1 and 80e2 that connect the upper wall 80a and the lower wall 80b. A positioning recess 81g is provided in each of the third and fourth lateral walls 80e1, 80e2.

図１６の図示例では、制止具９０の弧状部９６の形状が異なっている。このような場合においても、上述の説明が同様に当てはまる。 In the illustrated example of FIG. 16, the shape of the arcuate portion 96 of the stopper 90 is different. Even in such a case, the above description applies similarly.

図１６に示す場合、薄肉部９６ｎは、弧状の係合部９６の径方向内側、端的には、その径方向内端部に、係合部９６の上面から径方向内側に向かって下り傾斜する下り傾斜面９９ｍを有する。オプションとして、薄肉部９６ｎは、弧状の係合部９６の径方向内端部に、係合部９６の下面から径方向内側に上り傾斜する上り傾斜面９９ｎを有する。かかる場合にも、上述の説明と同様の効果が得られる。図１６の例に係るバックル１００の雄部材５０と雌部材７０の係合力は、図１乃至図１５に示したバックルの雄部材５０と雌部材７０の係合力よりも弱く、雄部材５０から雌部材７０を引き離す力により、操作部９１の操作無くして、雄部材５０と雌部材７０の係合又は連結を解除可能である。 In the case shown in FIG. 16, the thin-walled portion 96n is inclined downward from the upper surface of the engaging portion 96 toward the inner side in the radial direction, radially inward of the arcuate engaging portion 96, or in the radial inner end thereof. It has a down slope 99m. As an option, the thin-walled portion 96n has an upward inclined surface 99n inclined upward inward in the radial direction from the lower surface of the engaging portion 96 at the radially inner end portion of the arc-shaped engaging portion 96. In such a case, the same effect as described above can be obtained. The engaging force between the male member 50 and the female member 70 of the buckle 100 according to the example of FIG. 16 is weaker than the engaging force between the male member 50 and the female member 70 of the buckle shown in FIGS. The engagement or connection between the male member 50 and the female member 70 can be released without the operation of the operation portion 91 by the force that separates the member 70.

図１７及び図１８の図示例では、係合部９６は、薄肉部９６ｎのみから構成され、厚肉部９６ｍを含まない。連結部９７と薄肉部９６ｎが隣接して設けられる。かかる場合においても、可動部９３は、上述の解放位置から制止位置に向かう方向にて薄肉化された薄肉部９６ｎを有する。薄肉部９６ｎの厚みは、連結部９７の厚みよりも小さい。制止具９０により制止された状態の軸状突起５２の頭部５４が薄肉部９６ｎ上に配置されることが許容される。収容部材８０の上壁８０ａに頭部５４用の受容凹部を設ける必要がなく、上壁８０ａの上面のドーム部を無くし、又はその隆起の程度を低減することができる。つまり、このような例においても、上述したものと同様の効果を得ることができる。 In the illustrated examples of FIGS. 17 and 18, the engaging portion 96 includes only the thin portion 96n and does not include the thick portion 96m. The connecting portion 97 and the thin portion 96n are provided adjacent to each other. Even in such a case, the movable portion 93 includes the thin portion 96n that is thinned in the direction from the release position to the stop position. The thickness of the thin portion 96n is smaller than the thickness of the connecting portion 97. It is allowed that the head portion 54 of the shaft-like protrusion 52 in a state of being restrained by the restraining tool 90 is disposed on the thin portion 96n. It is not necessary to provide a receiving recess for the head 54 in the upper wall 80a of the housing member 80, and the dome portion on the upper surface of the upper wall 80a can be eliminated or the degree of the bulge can be reduced. That is, even in such an example, the same effect as described above can be obtained.

なお、薄肉部９６ｎの厚みが連結部９７の厚みよりも小さいことは、連結部９７が薄肉部９６ｎよりも小さい厚みの部分を含むことを排除しない。 Note that the fact that the thickness of the thin portion 96n is smaller than the thickness of the connecting portion 97 does not exclude that the connecting portion 97 includes a portion having a thickness smaller than that of the thin portion 96n.
