The outside represents a direction away from the axis AX10 in an arbitrary plane orthogonal to the axis AX10 illustrated in FIGS.
半径方向は、図1及び図2に図示の軸線AX10に直交する任意の平面において軸線AX10から離れる方向又は近づく方向を表わす。半径方向内側は、図1及び図2に図示の軸線AX10に直交する任意の平面において軸線AX10に近づく方向を表わす。半径方向外側は、図1及び図2に図示の軸線AX10に直交する任意の平面において軸線AX10から離れる方向を表わす。上面視及び下面視したときの雄型スナップボタンや雌型スナップボタンの円形状の形状を基礎として半径方向が理解される。   The radial direction represents a direction away from or approaching the axis AX10 in an arbitrary plane orthogonal to the axis AX10 illustrated in FIGS. The inner side in the radial direction represents a direction approaching the axis AX10 in an arbitrary plane orthogonal to the axis AX10 illustrated in FIGS. The radially outer side represents a direction away from the axis AX10 in an arbitrary plane orthogonal to the axis AX10 illustrated in FIGS. The radial direction is understood based on the circular shape of the male snap button and the female snap button when viewed from above and below.
周方向は、後述の雌型スナップボタン100の突起保持部120を周囲する方向である。周方向は、後述の雄型スナップボタン200の係合突起210を周囲する方向でもある。   The circumferential direction is a direction around a protrusion holding portion 120 of a female snap button 100 described later. The circumferential direction is also a direction around an engaging protrusion 210 of a male snap button 200 described later.
図1及び図2に示すように、スナップボタン900は、雌型スナップボタン100と、雄型スナップボタン200を含む。図示例においては、各スナップボタンが金属製であるが、必ずしもこの限りではなく、両方若しくは一方のスナップボタンの全体又は一部が樹脂部品により代替され得る。雌型スナップボタン100及び雄型スナップボタン200は、各々、生地300に対して取り付けられていることが図示されている。当業者は、本願の全開示に基づいて各生地300に対する各スナップボタンの取り付け方法も理解することができるだろう。   As shown in FIGS. 1 and 2, the snap button 900 includes a female snap button 100 and a male snap button 200. In the illustrated example, each snap button is made of metal. However, the present invention is not limited to this, and the whole or a part of both or one of the snap buttons can be replaced by a resin part. It is shown that the female snap button 100 and the male snap button 200 are each attached to the fabric 300. Those skilled in the art will also understand how to attach each snap button to each fabric 300 based on the entire disclosure of this application.
雄型スナップボタン200は、上面視及び下面視して円盤状に構成される基部205と、基部205の上面の中央に起立して設けられた略円柱状の係合突起210を有する。係合突起210は、軸線AX10に沿って上方に延びる。係合突起210は、その延在方向において首部211と頭部212を有する。係合突起210の頭部212は、係合突起210の首部211よりも外側及び半径方向外側に突出する。このように係合突起210の頭部212が首部211に比して拡径され、雌型スナップボタン100との良好なスナップ結合が確保される。   The male snap button 200 includes a base portion 205 configured in a disc shape when viewed from above and below, and a substantially cylindrical engagement protrusion 210 provided upright at the center of the upper surface of the base portion 205. The engagement protrusion 210 extends upward along the axis AX10. The engagement protrusion 210 has a neck portion 211 and a head portion 212 in the extending direction. The head portion 212 of the engaging protrusion 210 protrudes outward and radially outward from the neck portion 211 of the engaging protrusion 210. Thus, the head 212 of the engagement protrusion 210 is expanded in diameter as compared with the neck 211, and a good snap connection with the female snap button 100 is ensured.
図示例においては、雄型スナップボタン200は、2枚の金属部材201、202から構築されている。各金属部材201、202の各突起部分が重ね合わされ、上述の係合突起210が構成され、係合突起210の十分な強度が確保される。生地300の開口を通して生地300上に現れる金属部材201の突起部分を金属部材202の突起部分で被覆し、この半製品をプレス機によりプレス処理し、雄型スナップボタンを製造することができる。なお、雄型スナップボタン200の具体的な構成は任意であり、他の形態においては、樹脂の射出成形により製造される雄型スナップボタンが採用され得る。   In the illustrated example, the male snap button 200 is constructed from two metal members 201 and 202. The protruding portions of the metal members 201 and 202 are overlapped to form the engaging protrusion 210 described above, and sufficient strength of the engaging protrusion 210 is ensured. The protruding portion of the metal member 201 that appears on the fabric 300 through the opening of the fabric 300 is covered with the protruding portion of the metal member 202, and this semi-finished product is pressed by a press machine to produce a male snap button. The specific configuration of the male snap button 200 is arbitrary, and in other embodiments, a male snap button manufactured by resin injection molding may be employed.
雌型スナップボタン100は、回転子110、突起保持部120、板バネ130、及び収容部材140を含む。収容部材140内に回転子110、突起保持部120、及び板バネ130が配され及び収容される。収容部材140は、軸線AX10上における一対の開口を有する。収容部材140の上側の開口の開口幅は、下側の開口の開口幅よりも僅かに広い。回転子110は、収容部材140の上側の開口から突出した突出部117を有するが、突起保持部120や板バネ130と同様に収容部材140からの離脱が制限されており、従って、回転子110も収容部材140内に収容されているものと理解される。   The female snap button 100 includes a rotor 110, a protrusion holding part 120, a leaf spring 130, and a housing member 140. The rotor 110, the protrusion holding part 120, and the leaf spring 130 are disposed and housed in the housing member 140. The housing member 140 has a pair of openings on the axis AX10. The opening width of the upper opening of the housing member 140 is slightly wider than the opening width of the lower opening. The rotor 110 has a protruding portion 117 that protrudes from the upper opening of the housing member 140, but is separated from the housing member 140 in the same manner as the protrusion holding portion 120 and the leaf spring 130, and thus the rotor 110. Is also understood to be housed in the housing member 140.
突起保持部120は、雄型スナップボタン200の係合突起210の外周若しくは軸線AX10周りに配置される複数の「可動片」として一対のU字部121、122を含む。U字部121、122は、半径方向において移動することができる可動片である。雄型スナップボタン200の係合突起210の挿脱過程で各U字部121、122が外側及び半径方向外側に変位される。これら一対のU字部に関して、一方を第1U字部121と呼び、他方を第2U字部122と呼ぶ場合がある。なお、可動片の個数は、突起保持部120の分割数に依存する。突起保持部120を三分割する場合には、120°の範囲の三個の弧状部が可動片として働くことが予期される。   The protrusion holding portion 120 includes a pair of U-shaped portions 121 and 122 as a plurality of “movable pieces” disposed around the outer periphery of the engaging protrusion 210 of the male snap button 200 or around the axis AX10. The U-shaped parts 121 and 122 are movable pieces that can move in the radial direction. In the process of inserting / removing the engaging protrusion 210 of the male snap button 200, the U-shaped portions 121, 122 are displaced outward and radially outward. One of the pair of U-shaped portions may be called a first U-shaped portion 121 and the other may be called a second U-shaped portion 122. Note that the number of movable pieces depends on the number of divisions of the protrusion holding unit 120. When the projection holding part 120 is divided into three parts, it is expected that three arc-shaped parts in a range of 120 ° work as movable pieces.
U字部121、122は、雄型スナップボタン200の係合突起210を保持するように配され、各U字部121、122の各端部が隣接する時に略楕円形状の開口を形成する。雄型スナップボタン200の係合突起210の頭部212が円形状の上面視形状を呈し、従って、係合突起210が各U字部121、122の間で挟まれる時に係合突起210の抜き出しを阻止するように各U字部121、122が作用する。   The U-shaped parts 121 and 122 are arranged so as to hold the engaging protrusions 210 of the male snap button 200, and form substantially elliptical openings when the ends of the U-shaped parts 121 and 122 are adjacent to each other. The head 212 of the engagement protrusion 210 of the male snap button 200 has a circular top view, and therefore the engagement protrusion 210 is extracted when the engagement protrusion 210 is sandwiched between the U-shaped portions 121 and 122. The U-shaped portions 121 and 122 act so as to prevent the above.
各U字部121、122の各端部には外側及び半径方向外側に隆起した隆起部128が設けられる。隆起部128により収容部材140の内壁と突起保持部120間の隙間が減少し、安定した回動が促進される。   At each end of each U-shaped portion 121, 122 is provided a raised portion 128 that is raised outward and radially outward. The raised portion 128 reduces the gap between the inner wall of the housing member 140 and the protrusion holding portion 120, and promotes stable rotation.
収容部材140の底部147上に一対のU字部121、122及び板バネ130が載置され、一対のU字部121、122及び板バネ130上に回転子110が載置される。このようにして収容部材140の筒部146内に一対のU字部121、122、板バネ130、及び回転子110が配される。   A pair of U-shaped portions 121 and 122 and a leaf spring 130 are placed on the bottom 147 of the housing member 140, and the rotor 110 is placed on the pair of U-shaped portions 121 and 122 and the leaf spring 130. In this way, the pair of U-shaped portions 121 and 122, the leaf spring 130, and the rotor 110 are arranged in the cylindrical portion 146 of the housing member 140.
回転子110、突起保持部120(一対のU字部121、122)、及び板バネ130が一緒に回転する回転ユニットを構築する。回転子110の上面には鍵部材400を嵌め合わせることができる上溝118が設けられている。回転子110に付与される回転力が、突起保持部120及び板バネ130に伝達される。   A rotating unit is constructed in which the rotor 110, the protrusion holding portion 120 (the pair of U-shaped portions 121 and 122), and the leaf spring 130 rotate together. An upper groove 118 in which the key member 400 can be fitted is provided on the upper surface of the rotor 110. A rotational force applied to the rotor 110 is transmitted to the protrusion holding part 120 and the leaf spring 130.
図示例においては、回転子110から突起保持部120及び板バネ130に回転力を伝達するため、回転子110の下面には上溝118に直交する方向に延びる下溝119が設けられる。各U字部121、122には回転子110の下溝119に嵌め合わされる上方凸部129が設けられる。板バネ130にも回転子110の下溝119に嵌め合わされる上方凸部139が設けられる。このようにして回転子110からの回転力が、各U字部121、122に伝達し、また同様に板バネ130に伝達する。なお、回転ユニット内における各部品の配置態様、連結態様、及び各部品間の回転力の伝達方法は任意であり、他の様々な形態も想定される。   In the illustrated example, a lower groove 119 extending in a direction perpendicular to the upper groove 118 is provided on the lower surface of the rotor 110 in order to transmit a rotational force from the rotor 110 to the protrusion holding portion 120 and the leaf spring 130. Each U-shaped part 121, 122 is provided with an upper convex part 129 that fits into the lower groove 119 of the rotor 110. The leaf spring 130 is also provided with an upper protrusion 139 that is fitted in the lower groove 119 of the rotor 110. In this way, the rotational force from the rotor 110 is transmitted to the U-shaped portions 121 and 122 and also to the leaf spring 130. In addition, the arrangement | positioning aspect of each component in a rotation unit, a connection aspect, and the transmission method of the rotational force between each components are arbitrary, and other various forms are also assumed.
図示例においては、収容部材140が、3つの金属部材141、142、143から構築されている。金属部材141は、突起保持部120及び板バネ130が載置される円形状の底部147を有し、底部147の中央には雄型スナップボタン200の係合突起210の通過用の円形状の開口が設けられる。円形状の底部147の外周から壁板が起立し、これにより筒部146の内壁部分が構成される。生地300への取り付け後、図1及び図2に示すように、金属部材141の筒部の上端部が外側及び半径方向外側に巻かれる。   In the illustrated example, the housing member 140 is constructed from three metal members 141, 142, and 143. The metal member 141 has a circular bottom portion 147 on which the protrusion holding portion 120 and the leaf spring 130 are placed, and a circular shape for passing the engagement protrusion 210 of the male snap button 200 is provided at the center of the bottom portion 147.

金属部材142は、金属部材141の外周に設けられる。金属部材142は、生地300の下面を押さえる環状の押圧部を有し、押圧部の内周から壁板が起立し、これにより筒部の外壁部分が構成される。金属部材142の筒部の内面が金属部材141の筒部の外面に接触し、高められた強度の2層構造の筒部146が構築される。生地300への取り付け後、図1及び図2に示すように、金属部材142の筒部の上端部が外側及び半径方向外側に巻かれ、金属部材141の筒部の上端部の巻き部内に保持される。   The metal member 142 is provided on the outer periphery of the metal member 141. The metal member 142 has an annular pressing portion that presses the lower surface of the fabric 300, and a wall plate rises from the inner periphery of the pressing portion, thereby forming an outer wall portion of the cylindrical portion. The inner surface of the cylindrical portion of the metal member 142 is in contact with the outer surface of the cylindrical portion of the metal member 141, and the cylindrical portion 146 having a two-layer structure with increased strength is constructed. After the attachment to the cloth 300, as shown in FIGS. 1 and 2, the upper end portion of the cylindrical portion of the metal member 142 is wound outward and radially outward and held in the winding portion of the upper end portion of the cylindrical portion of the metal member 141. Is done.
金属部材143は、回転子110の外周部上に配される環状の表板部を含む。環状の表板部の開口から上述の回転子110の突出部117が突出する。金属部材143は、更に、環状の表板部の外周から下降して金属部材141及び金属部材142の各上端の巻き部に係合するスカート部を含む。生地300が金属部材142と金属部材143により挟み込まれ、これにより生地300への雌型スナップボタン100の取り付けが完了する。   The metal member 143 includes an annular front plate portion disposed on the outer peripheral portion of the rotor 110. The projecting portion 117 of the rotor 110 projects from the opening of the annular front plate portion. The metal member 143 further includes a skirt portion that descends from the outer periphery of the annular front plate portion and engages with the winding portions at the upper ends of the metal member 141 and the metal member 142. The fabric 300 is sandwiched between the metal member 142 and the metal member 143, thereby completing the attachment of the female snap button 100 to the fabric 300.
図3は、雄型スナップボタン200の係合突起210の離脱を許容する非ロック状態を示す。図3に示すように、収容部材140内において突起保持部120が内側に配され、板バネ130が外側及び半径方向外側に配される。板バネ130は、突起保持部120を周囲する周方向に延びる板バネである。板バネ130は、周方向に長尺な板バネである。板バネ130は、周方向において各U字部121よりも長く延びる。板バネ130は、雄型スナップボタン200の係合突起210の挿脱時に外側及び半径方向外側に変位した各U字部121、122を内側に付勢することができる。   FIG. 3 shows an unlocked state in which the engagement protrusion 210 of the male snap button 200 is allowed to be disengaged. As shown in FIG. 3, in the housing member 140, the protrusion holding part 120 is arranged on the inner side, and the leaf spring 130 is arranged on the outer side and the outer side in the radial direction. The leaf spring 130 is a leaf spring that extends in the circumferential direction around the protrusion holding portion 120. The leaf spring 130 is a leaf spring that is long in the circumferential direction. The leaf spring 130 extends longer than each U-shaped portion 121 in the circumferential direction. The leaf spring 130 can bias the U-shaped portions 121 and 122 displaced outward and radially outward when the engaging protrusion 210 of the male snap button 200 is inserted and removed.
本実施形態においては、複数の可動片若しくはU字部に対して共通の板バネが採用される。これにより、各可動片若しくはU字部に対応して各板バネを用意し、これらの細々した部品を収容部材内に適切に配置することの労力が低減される。雌型スナップボタンの組み立ての簡素化及び雌型スナップボタンの製造コストの低減が促進される。   In the present embodiment, a common leaf spring is employed for a plurality of movable pieces or U-shaped portions. Thereby, each leaf | plate spring is prepared corresponding to each movable piece or a U-shaped part, and the effort of arrange | positioning these fine components in a storage member appropriately is reduced. Simplification of assembly of the female snap button and reduction of the manufacturing cost of the female snap button are promoted.
板バネ130は、C字状若しくはランドルト環状に構成される。板バネ130は、両端の間の隙間を除いて突起保持部120を周囲する。板バネ130は、一端131と他端132を有し、その間に隙間が存在する。板バネ130は、一端131と他端132の間に1以上又は複数の屈曲部を有し、図示例においては第1屈曲部133と第2屈曲部134を有する。板バネ130は、第1屈曲部133と第2屈曲部134において収容部材140の内壁に強く接触する。   The leaf spring 130 is configured in a C shape or a Landolt ring. The leaf spring 130 surrounds the protrusion holding portion 120 except for a gap between both ends. The leaf spring 130 has one end 131 and the other end 132, and there is a gap between them. The leaf spring 130 has one or more bent portions between one end 131 and the other end 132, and has a first bent portion 133 and a second bent portion 134 in the illustrated example. The leaf spring 130 strongly contacts the inner wall of the housing member 140 at the first bent portion 133 and the second bent portion 134.
幾つかの実施形態においては、板バネ130の両端間の隙間は、上述の周方向における各可動片121、122の長さよりも短い。幾つかの実施形態においては、板バネ130の両端間の隙間が、突起保持部120により保持された雄型スナップボタン200の係合突起210の全周の1/4未満の範囲の周方向における長さを有する。係合突起210の全周は360°であり、その1/4は90°である。適切な隙間の設定により適切なバネ力が設定可能である。幾つかの実施形態においては、図3に示す直交関係の第1及び第2仮想線により区画される4つの領域の一つ領域内に板バネ130の両方の端部が存在する。図3に示す時、第1仮想線が、各可動片121、122の可動方向に一致する。第2仮想線は、第1仮想線に直交する。   In some embodiments, the gap between both ends of the leaf spring 130 is shorter than the length of each movable piece 121, 122 in the circumferential direction described above. In some embodiments, the gap between both ends of the leaf spring 130 is in the circumferential direction in a range that is less than ¼ of the entire circumference of the engagement protrusion 210 of the male snap button 200 held by the protrusion holding part 120. Have a length. The entire circumference of the engagement protrusion 210 is 360 °, and ¼ of the entire circumference is 90 °. An appropriate spring force can be set by setting an appropriate gap. In some embodiments, both ends of the leaf spring 130 exist in one of the four regions defined by the orthogonally related first and second imaginary lines shown in FIG. As shown in FIG. 3, the first virtual line coincides with the movable direction of each of the movable pieces 121 and 122. The second imaginary line is orthogonal to the first imaginary line.
第1屈曲部133と一端131の間の部分が角度αを有するように内側に曲げられており、一端131が後述の制限突起145mを乗り越える際の板バネ130の変形量が低減される。なお、板バネ130の変形量が大きいと、板バネ130が塑性変形してしまうおそれがある。   A portion between the first bent portion 133 and the one end 131 is bent inward so as to have an angle α, and the amount of deformation of the leaf spring 130 when the one end 131 gets over a limit protrusion 145m described later is reduced. If the amount of deformation of the leaf spring 130 is large, the leaf spring 130 may be plastically deformed.
第1屈曲部133と第2屈曲部134の間には円弧状の弧状部135が設けられる。第1屈曲部133と第2屈曲部134の間に更なる屈曲部が設けられず、これにより、非ロック状態からロック状態への切り替え時の回転の容易性が確保される。弧状部135は、収容部材140の中心軸を中心とした同心円上であり、第1屈曲部133と第2屈曲部134は、この弧状部135の同心円の仮想線から半径方向外側に突出する部分と言うこともできる。   An arcuate portion 135 having an arc shape is provided between the first bent portion 133 and the second bent portion 134. No further bent portion is provided between the first bent portion 133 and the second bent portion 134, thereby ensuring the ease of rotation when switching from the unlocked state to the locked state. The arc-shaped portion 135 is on a concentric circle with the central axis of the housing member 140 as the center, and the first bent portion 133 and the second bent portion 134 are portions that protrude radially outward from the imaginary line of the concentric circle of the arc-shaped portion 135. It can also be said.
なお、一端131と第1屈曲部133の間に第1の上方凸部139が設けられる。他端132と第2屈曲部134の間に第2の上方凸部139が設けられる。第1屈曲部133と第2屈曲部134は突起保持部120を挟んで反対の位置に設けられる。   A first upward convex portion 139 is provided between the one end 131 and the first bent portion 133. A second upward convex portion 139 is provided between the other end 132 and the second bent portion 134. The first bent portion 133 and the second bent portion 134 are provided at opposite positions across the protrusion holding portion 120.
非ロック状態において、雄型スナップボタン200の係合突起210の上面視正円状の頭部212が第1U字部121と第2U字部122の間の楕円形状の開口を通過する際、係合突起210の頭部212が第1U字部121と第2U字部122を半径方向外側へ変位させ、これにより第1U字部121と第2U字部122の間隔が広がり、係合突起210の頭部212の通過が許容される。次に、板バネ130は、半径方向外側へ変位した第1U字部121と第2U字部122のそれぞれを半径方向内側へ変位させ、それぞれを元の位置若しくは元の位置側へ押し戻すべく作動する。   In the unlocked state, when the head 212 having a circular shape in a top view of the engagement protrusion 210 of the male snap button 200 passes through the elliptical opening between the first U-shaped part 121 and the second U-shaped part 122, The head portion 212 of the mating protrusion 210 displaces the first U-shaped portion 121 and the second U-shaped portion 122 outward in the radial direction, thereby increasing the distance between the first U-shaped portion 121 and the second U-shaped portion 122, and The passage of the head 212 is allowed. Next, the leaf spring 130 operates to displace each of the first U-shaped portion 121 and the second U-shaped portion 122 displaced outward in the radial direction radially inward and push them back to the original position or the original position. .
詳細には、係合突起210の頭部212の通過の過程で、板バネ130の一端131と第1屈曲部133の間の区分が第1U字部121により半径方向外側へ押され、その後、同区分が第1U字部121を内側へ押し戻す。同様に、係合突起210の頭部212の通過の過程で、第1屈曲部133よりも第2屈曲部134の近傍にある弧状部135の区分が第2U字部122により半径方向外側へ押され、その後、同区分が第2U字部122を内側へ押し戻す。板バネ130のこのような作動に基づいて、第1U字部121と第2U字部122の間隔が狭まり、雄型スナップボタン200の係合突起210が第1U字部121と第2U字部122から構成された突起保持部120により保持される。つまり、非ロック状態では、雌型スナップボタン100に対して雄型スナップボタン200が着脱可能である。後述のロック状態では、雌型スナップボタン100に保持された雄型スナップボタン200が雌型スナップボタン100から離脱し難い状態にある。   Specifically, in the process of passage of the engagement protrusion 210 through the head portion 212, the section between the one end 131 of the leaf spring 130 and the first bent portion 133 is pushed radially outward by the first U-shaped portion 121, and then The same section pushes back the first U-shaped portion 121 inward. Similarly, in the process of passage of the engagement protrusion 210 through the head portion 212, the section of the arc-shaped portion 135 that is closer to the second bent portion 134 than the first bent portion 133 is pushed outward in the radial direction by the second U-shaped portion 122. Then, the same section pushes back the second U-shaped portion 122 inward. Based on such an operation of the leaf spring 130, the distance between the first U-shaped portion 121 and the second U-shaped portion 122 is narrowed, and the engagement protrusion 210 of the male snap button 200 is moved to the first U-shaped portion 121 and the second U-shaped portion 122. It is held by the protrusion holding part 120 constituted by That is, in the unlocked state, the male snap button 200 can be attached to and detached from the female snap button 100. In the locked state described later, the male snap button 200 held by the female snap button 100 is in a state in which it is difficult to detach from the female snap button 100.
図4に示すように、回転子110の上面には鍵部材400を嵌め合わせることができる上溝118が設けられている。図5に鍵部材400の一例が図示されている。回転子110に対して鍵部材400を嵌合し、鍵部材400を回転させることにより回転子110が回転し、これに従い、突起保持部120及び板バネ130が回転する。上溝118をH字状としても良く、これ以外の文字・模様としても構わない。回転子110に凸部を設け、鍵部材400に凹部を設け、これにより両者の嵌合を確保しても構わない。つまり、回転子110と鍵部材400の各嵌合部が相補的に形状付けられて回転子110と鍵部材400の嵌合が達成される。   As shown in FIG. 4, an upper groove 118 into which the key member 400 can be fitted is provided on the upper surface of the rotor 110. An example of the key member 400 is shown in FIG. By fitting the key member 400 to the rotor 110 and rotating the key member 400, the rotor 110 rotates, and the protrusion holding portion 120 and the leaf spring 130 rotate accordingly. The upper groove 118 may be H-shaped, or other characters / patterns may be used. The rotor 110 may be provided with a convex portion, and the key member 400 may be provided with a concave portion, thereby ensuring the fitting of both. That is, the fitting portions of the rotor 110 and the key member 400 are complementarily shaped, and the fitting of the rotor 110 and the key member 400 is achieved.
突起保持部120及び板バネ130の回転過程が図6乃至図9に図示されている。なお、図6は、雌型スナップボタン100の非ロック状態を示す。図9は、雌型スナップボタン100のロック状態を示す。上述のように回転子110、突起保持部120、及び板バネ130が一緒に回転し、これらにより回転ユニットが構築される。図6に示す時、第1U字部121と第2U字部122の間隔が広がる方向上に各制限突起145が存在せず、回転ユニットが非ロック位置にある。図9に示す時、第1U字部121と第2U字部122の間隔が広がる方向上に各制限突起145が存在し、回転ユニットがロック位置にある。   The rotation process of the protrusion holding part 120 and the leaf spring 130 is shown in FIGS. FIG. 6 shows the unlocked state of the female snap button 100. FIG. 9 shows a locked state of the female snap button 100. As described above, the rotor 110, the protrusion holding unit 120, and the leaf spring 130 rotate together, and a rotation unit is constructed by these. As shown in FIG. 6, the restricting projections 145 are not present in the direction in which the distance between the first U-shaped portion 121 and the second U-shaped portion 122 is widened, and the rotating unit is in the unlocked position. As shown in FIG. 9, each limiting protrusion 145 exists in the direction in which the distance between the first U-shaped portion 121 and the second U-shaped portion 122 widens, and the rotating unit is in the locked position.
収容部材140には2以上の制限突起145が設けられる。図示例においては、2つの制限突起145が設けられ、2つの制限突起145が突起保持部120を挟んで反対の位置に設けられる。以下、第1制限突起145mと第2制限突起145nと区別して説明する場合がある。回転子110の回動に応じて板バネ130が時計回りに回転する時、板バネ130の一端131が第1制限突起145mを乗り越える。図7に図示のごとく、板バネ130の一端131が第1制限突起145mの傾斜面を上る。図8に図示のごとく、板バネ130の一端131が第1制限突起145mを乗り越え、板バネ130の一端131が第1制限突起145mの頂部に沿って移動する。図9に図示のごとく、板バネ130の一端131が第1制限突起145mを通過する。非ロック状態からロック状態への切り替えの過程(非ロック状態からロック状態への推移の過程、とも言う)で板バネ130の一端131が制限突起145を乗り越えることにより切り替えの操作感を得ることが可能になる。図9に示す時、板バネ130の一端131は、図9に示す第1U字部121の端部と第2U字部122の端部の隙間及び収容部材140の中心軸を通る第1仮想線と、この第1仮想線に直交する第2仮想線の間に位置している。   The housing member 140 is provided with two or more restricting protrusions 145. In the illustrated example, two limiting protrusions 145 are provided, and the two limiting protrusions 145 are provided at opposite positions with the protrusion holding portion 120 interposed therebetween. Hereinafter, the first limiting protrusion 145m and the second limiting protrusion 145n may be described separately. When the leaf spring 130 rotates clockwise according to the rotation of the rotor 110, one end 131 of the leaf spring 130 gets over the first limiting protrusion 145m. As shown in FIG. 7, one end 131 of the leaf spring 130 goes up the inclined surface of the first limiting protrusion 145m. As shown in FIG. 8, one end 131 of the leaf spring 130 gets over the first limiting protrusion 145m, and the one end 131 of the leaf spring 130 moves along the top of the first limiting protrusion 145m. As shown in FIG. 9, one end 131 of the leaf spring 130 passes through the first limiting protrusion 145m. When one end 131 of the leaf spring 130 gets over the restricting protrusion 145 in the process of switching from the unlocked state to the locked state (also referred to as a transition process from the unlocked state to the locked state), a switching operation feeling can be obtained. It becomes possible. 9, the one end 131 of the leaf spring 130 is a first imaginary line that passes through the gap between the end of the first U-shaped portion 121 and the end of the second U-shaped portion 122 and the central axis of the housing member 140 shown in FIG. And the second imaginary line orthogonal to the first imaginary line.
非ロック状態とロック状態の間の状態切り替えの過程で、板バネ130の各屈曲部133、134は各制限突起145を乗り越えることがなく、回転子110の相対的に軽い回転が確保される。板バネ130の第1屈曲部133と第2屈曲部134の間には弧状部135が設けられる。非ロック状態からロック状態への切り替え過程で弧状部135が第2制限突起145nに接触する。しかしながら、弧状部135は屈曲部を持たないため、第2制限突起145nと弧状部135とが強く接触することが回避され、回転子110の相対的に軽い回転が確保される。   In the process of switching the state between the unlocked state and the locked state, the bent portions 133 and 134 of the leaf spring 130 do not get over the restricting protrusions 145, and a relatively light rotation of the rotor 110 is ensured. An arcuate portion 135 is provided between the first bent portion 133 and the second bent portion 134 of the leaf spring 130. In the process of switching from the unlocked state to the locked state, the arc-shaped portion 135 contacts the second limiting protrusion 145n. However, since the arc-shaped portion 135 does not have a bent portion, it is avoided that the second limiting protrusion 145n and the arc-shaped portion 135 are in strong contact, and a relatively light rotation of the rotor 110 is ensured.
図9に示すロック状態においては、雄型スナップボタン200の係合突起210が雌型スナップボタン100の突起保持部120に保持される。突起保持部120から係合突起210を抜き出させる場合、係合突起210の頭部212から受ける力に応じて各U字部121、122が半径方向外側へ変位しようとする。しかしながら、図9に示すごとく、各U字部121、122の両端間の中央部の半径方向外側には各制限突起145が位置し、これにより各U字部121、122の半径方向外側の変位が各制限突起145により制限される。従って、雌型スナップボタン100の突起保持部120からの雄型スナップボタン200の係合突起210の離脱が阻止される。なお、各U字部121、122の両端間の中央部は、板バネ130を間に挟んで制限突起145により動きが制限されるため被制限部と呼んでも構わない。   In the locked state shown in FIG. 9, the engagement protrusion 210 of the male snap button 200 is held by the protrusion holding portion 120 of the female snap button 100. When the engaging protrusion 210 is extracted from the protrusion holding part 120, each U-shaped part 121, 122 tends to be displaced radially outward in accordance with the force received from the head 212 of the engaging protrusion 210. However, as shown in FIG. 9, the restricting protrusions 145 are located on the radially outer side of the central portion between the both ends of the U-shaped portions 121 and 122, and thereby the displacement of the U-shaped portions 121 and 122 on the radially outer side. Is limited by each limiting protrusion 145. Accordingly, the engagement protrusion 210 of the male snap button 200 from the protrusion holding portion 120 of the female snap button 100 is prevented from being detached. The central part between both ends of each U-shaped part 121, 122 may be called a restricted part because the movement is restricted by the restricting protrusion 145 with the leaf spring 130 interposed therebetween.
なお、図6の非ロック状態においては、各U字部121、122の両端間の中央部の半径方向外側には制限突起145が配されていない。むしろ、各U字部121、122の端部の半径方向外側に制限突起145が配されている。この場合、各U字部121、122の半径方向外側への移動が制限突起145により何ら制限されず、従って、雄型スナップボタン200の係合突起210を雌型スナップボタン100の突起保持部120に挿入し、また雌型スナップボタン100の突起保持部120から雄型スナップボタン200の係合突起210を離脱することが許容される。   In the unlocked state of FIG. 6, the limiting protrusion 145 is not disposed on the radially outer side of the central portion between both ends of each U-shaped portion 121, 122. Rather, the limiting protrusion 145 is disposed on the outer side in the radial direction of the end portion of each U-shaped portion 121, 122. In this case, the movement of the U-shaped portions 121, 122 outward in the radial direction is not restricted at all by the restricting protrusion 145, and therefore the engaging protrusion 210 of the male snap button 200 is replaced with the protrusion holding section 120 of the female snap button 100. And the engaging protrusion 210 of the male snap button 200 is allowed to be disengaged from the protrusion holding portion 120 of the female snap button 100.
板バネ130は、図10に示すような形状を収容部材140内において取るが、収容部材140から板バネ130を取り出せば、当然、そのバネ性に基づいて板バネ130の両端間の隙間が減じられた形状に変化する。   The leaf spring 130 has a shape as shown in FIG. 10 in the housing member 140. However, if the leaf spring 130 is taken out of the housing member 140, the gap between the both ends of the leaf spring 130 is naturally reduced based on the spring property. Changes to the shape.
雌型スナップボタン100の製造方法については、U字部121、122を収容部材140内に配置する工程と、板バネ130を収容部材140内に配置する工程を含む。収容部材140内に突起保持部120を先に配置し、次に収容部材140内に板バネ130を配置しても良く、この逆であっても構わない。   The method for manufacturing the female snap button 100 includes a step of placing the U-shaped portions 121 and 122 in the housing member 140 and a step of placing the leaf spring 130 in the housing member 140. The protrusion holding portion 120 may be disposed first in the housing member 140, and then the leaf spring 130 may be disposed in the housing member 140, or vice versa.
上述の実施形態とは異なり、図11に示すような通常形状の板バネ130を用いることも想定される。図11に示す場合、第1屈曲部133と第2屈曲部134の間に第3屈曲部136が設けられる。突起保持部120により拡径されて図11の板バネ130が、その一端131、第1屈曲部133、第2屈曲部134、及び第3屈曲部136の4カ所で収容部材140の内壁に接触する。この場合、板バネ130の一端131が制限突起145mに衝突するよりも第3屈曲部136が制限突起145nに衝突し、回転子110の回転が重くなることが予想される。また、板バネ130の一端131が制限突起145mを乗り越えるとき、板バネ130の一端131の近傍での板バネの変形量が大きくなり、板バネ130が塑性変形してしまうおそれもある。   Unlike the above-described embodiment, it is also assumed that a leaf spring 130 having a normal shape as shown in FIG. 11 is used. In the case shown in FIG. 11, a third bent portion 136 is provided between the first bent portion 133 and the second bent portion 134. The leaf spring 130 of FIG. 11 is expanded in diameter by the protrusion holding portion 120 and contacts the inner wall of the housing member 140 at four locations of its one end 131, first bent portion 133, second bent portion 134, and third bent portion 136. To do. In this case, it is expected that the third bent portion 136 collides with the restricting projection 145n and the rotation of the rotor 110 becomes heavier than the one end 131 of the leaf spring 130 collides with the restricting projection 145m. Further, when the one end 131 of the leaf spring 130 gets over the limiting protrusion 145m, the amount of deformation of the leaf spring near the one end 131 of the leaf spring 130 increases, and the leaf spring 130 may be plastically deformed.
図12乃至図14を参照して他の実施形態について説明する。図12は、別の実施形態に係る雌型スナップボタンの概略的な垂直断面模式図である。図13は、別の実施形態に係る雌型スナップボタンの概略的な水平断面模式図であり、雌型スナップボタンが非ロック状態にある。図14は、別の実施形態に係る雌型スナップボタンの概略的な水平断面模式図であり、雌型スナップボタンがロック状態にある。   Another embodiment will be described with reference to FIGS. FIG. 12 is a schematic vertical cross-sectional view of a female snap button according to another embodiment. FIG. 13 is a schematic horizontal cross-sectional view of a female snap button according to another embodiment, and the female snap button is in an unlocked state. FIG. 14 is a schematic horizontal cross-sectional view of a female snap button according to another embodiment, and the female snap button is in a locked state.
第1の実施形態においては、非ロック状態とロック状態の間で突起保持部120及び板バネ130が回転子110に同調して回転し、他方、収容部材140に設けられた制限突起145が回転していなかった。他方、図12乃至図14に提示の本実施形態においては、非ロック状態とロック状態の間で突起保持部120及び板バネ130が回転せず、他方、回転子110の底面の外周部に設けられた一対の制限脚部115が回転する。このような形態においても上述の実施形態において説明したものと同様の利益を得ることができる。なお、第1の実施形態の制限突起145と本実施形態の制限脚部115を包括して制限部若しくは制限手段若しくは制限構造と呼ぶ場合がある。   In the first embodiment, the protrusion holding portion 120 and the leaf spring 130 rotate in synchronization with the rotor 110 between the unlocked state and the locked state, while the limiting protrusion 145 provided on the housing member 140 rotates. I did not. On the other hand, in the present embodiment shown in FIGS. 12 to 14, the protrusion holding portion 120 and the leaf spring 130 do not rotate between the unlocked state and the locked state, and on the other hand, provided on the outer peripheral portion of the bottom surface of the rotor 110. The pair of restriction legs 115 thus rotated rotate. Also in such a form, the same profit as what was demonstrated in the above-mentioned embodiment can be acquired. The restricting protrusion 145 of the first embodiment and the restricting leg 115 of the present embodiment may be collectively referred to as a restricting portion, a restricting means, or a restricting structure.
図12に示すように、板バネ130と収容部材140の筒部146の間には回転子110の制限脚部115が配される。図13の非ロック状態から図14のロック状態へ回転子110が反時計回りに回転される。このとき、回転子110の第1制限脚部115mが板バネ130の一端131を通過し、回転子110の第2制限脚部115nが板バネ130の弧状部135に沿って移動する。このような場合においても、非ロック状態からロック状態への切り替え過程での操作感を得ることができ、また相対的に軽い回転子110の回転を確保することができる。   As shown in FIG. 12, the restricting leg portion 115 of the rotor 110 is disposed between the leaf spring 130 and the cylindrical portion 146 of the housing member 140. The rotor 110 is rotated counterclockwise from the unlocked state of FIG. 13 to the locked state of FIG. At this time, the first restriction leg 115m of the rotor 110 passes through one end 131 of the leaf spring 130, and the second restriction leg 115n of the rotor 110 moves along the arcuate portion 135 of the leaf spring 130. Even in such a case, a feeling of operation in the process of switching from the unlocked state to the locked state can be obtained, and a relatively light rotation of the rotor 110 can be ensured.
図15を参照して更なる他の実施形態について説明する。図15は、更に別の実施形態に係る雌型スナップボタンの概略的な垂直断面模式図である。なお、図15を参照して説明する本実施形態は、上述した二つの実施形態に対して追加の特徴を提供する。しかしながら、図15を参照して説明する本実施形態は、上述した二つの実施形態とは無関係に独立して実施することもできる。   Still another embodiment will be described with reference to FIG. FIG. 15 is a schematic vertical sectional view of a female snap button according to still another embodiment. Note that the present embodiment described with reference to FIG. 15 provides additional features to the two embodiments described above. However, this embodiment described with reference to FIG. 15 can also be implemented independently of the above-described two embodiments.
図15に示すように回転子110には被覆部材500が嵌め合わされる。被覆部材500は、回転子110に対して着脱可能であるか、若しくは着脱不能である。被覆部材500を設けることにより、回転子110よりもサイズが大きい被覆部材500を回転させることにより、鍵部材400を用いることなく簡単に回転子110を回転させることができる。被覆部材500の外観は、意匠が施された又は施されていない任意形状のボタンであり得る。被覆部材500は、雌型スナップボタン100のロック機能の隠蔽にも寄与する。   As shown in FIG. 15, the covering member 500 is fitted to the rotor 110. The covering member 500 is attachable / detachable with respect to the rotor 110 or is not attachable / detachable. By providing the covering member 500, the rotor 110 can be easily rotated without using the key member 400 by rotating the covering member 500 having a size larger than that of the rotor 110. The appearance of the covering member 500 may be a button having an arbitrary shape with or without a design. The covering member 500 also contributes to concealing the lock function of the female snap button 100.
図示例の被覆部材500は、円形状の平板部510と、円形状の平板部510の中心に設けられた凸部520と、円形状の平板部510の外周から下方に延びるフランジ部530を有する。被覆部材500の平板部510が収容部材140の直径若しくは幅よりも大きい直径若しくは幅を有する。従って、被覆部材500を把持することが簡単に確保される。被覆部材500の凸部520は、回転子110の上溝118に対して相補的な形状を有する。回転子110と鍵部材400の関係と同様、回転子110と被覆部材500の各嵌合部が相補的な形状に構成されて回転子110と被覆部材500の嵌合が達成される。被覆部材500を回転させることにより回転子110が回転し、従って、第1の実施形態と同様、突起保持部120及び板バネ130が周方向に回転する。このようにして雌型スナップボタン100のロック状態と非ロック状態の切り替えが実行される。   The covering member 500 in the illustrated example includes a circular flat plate portion 510, a convex portion 520 provided at the center of the circular flat plate portion 510, and a flange portion 530 that extends downward from the outer periphery of the circular flat plate portion 510. . The flat plate portion 510 of the covering member 500 has a diameter or width larger than the diameter or width of the housing member 140. Therefore, it is easily ensured that the covering member 500 is gripped. The convex portion 520 of the covering member 500 has a shape complementary to the upper groove 118 of the rotor 110. Similar to the relationship between the rotor 110 and the key member 400, the fitting portions of the rotor 110 and the covering member 500 are formed in complementary shapes, and the fitting of the rotor 110 and the covering member 500 is achieved. By rotating the covering member 500, the rotor 110 rotates, and thus the protrusion holding portion 120 and the leaf spring 130 rotate in the circumferential direction as in the first embodiment. In this way, the female snap button 100 is switched between the locked state and the unlocked state.
本願には以下の付記にて特定の雌型スナップボタンも開示されている。この雌型スナップボタンで特定される付勢手段は、本願に開示の単一の板バネ130に限られず、特許文献1及び2に開示のような複数の板バネ130の使用も包含する点に留意されたい。制限手段についても、制限突起や制限脚部若しくはこれら以外の部分、構造を含む。   The present application also discloses specific female snap buttons as described below. The biasing means specified by the female snap button is not limited to the single leaf spring 130 disclosed in the present application, but includes the use of a plurality of leaf springs 130 as disclosed in Patent Documents 1 and 2. Please keep in mind. The restricting means also includes a restricting protrusion, a restricting leg portion, a portion other than these, and a structure.
