以下、本発明の実施形態について、図面に基づいて説明する。なお、本発明は、ここに記載される実施形態に限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiment described here.

「実施形態の構成」
図１は、実施形態に係るロック機構の構成及び動作を示す図であり、（ａ）はロック時、（ｂ）はロック解除動作（押圧）時、（ｃ）はロック解除（非押圧）時の状態を示す。 "Configuration of the embodiment"
1A and 1B are diagrams showing the configuration and operation of a lock mechanism according to an embodiment, wherein FIG. 1A shows a locked state, FIG. 1B shows a unlocked state (pressed), and FIG. The state of is shown.

ロック機構１０は、オス部材１２と、メス部材１４を含む。ロック機構１０の対象がホースクランプであれば、ホースの周囲に配置される解放円形リングの一端がオス部材１２に接続され、他端がメス部材１４に接続される。   The lock mechanism 10 includes a male member 12 and a female member 14. If the object of the lock mechanism 10 is a hose clamp, one end of a release circular ring arranged around the hose is connected to the male member 12, and the other end is connected to the female member 14.

オス部材１２は、解放円形リングの一端が接続される一端側の円板状のオス基部１２−１、オス基部１２−１から伸びるオス基部１２−１より小径であって中実（柱状）のオス円筒部１２−２、オス円筒部１２−２から伸びるオス先細り部１２−３、オス先細り部１２−３の先端部のオス小径部１２−４、オス小径部１２−４から径が拡がって先端側に伸びるオス先端円筒部１２−５、オス先端円筒部１２−５の先端側に伸びるオス先端先細り部１２−６を有する。オス部材１２はその先端側がメス部材１４に挿入される。   The male member 12 has a disk-shaped male base 12-1 at one end to which one end of the open circular ring is connected, and a smaller diameter than the male base 12-1 extending from the male base 12-1, and is solid (columnar). The male cylindrical portion 12-2, the male tapered portion 12-3 extending from the male cylindrical portion 12-2, the male small diameter portion 12-4 at the tip of the male tapered portion 12-3, and the diameter expanding from the male small diameter portion 12-4. It has a male tip cylindrical portion 12-5 extending to the tip side, and a male tip taper portion 12-6 extending to the tip side of the male tip cylindrical portion 12-5. The tip side of the male member 12 is inserted into the female member 14.

メス部材１４は、解放円形リングの他端に接続される。メス部材１４は、オス円筒部１２−２の外周側に対応する内径を持つメス筒部１４−１、メス筒部１４−１から先端側に伸び内径がオス先細り部１２−３の周面に対応して徐々に小さくなるメス先細り部１４−２、メス先細り部１４−２の先端部に位置するメス小径爪１４−３、メス小径爪１４−３から外側に折り返すようにして一端側に向けて斜め外方に伸びるメス返し部１４−４、メス返し部１４−４の一端側に形成されたメスつまみ部１４−５、メスつまみ部１４−５の内方に膨出するメス膨出部１４−６を有する。   The female member 14 is connected to the other end of the release circular ring. The female member 14 has a female cylindrical portion 14-1 having an inner diameter corresponding to the outer peripheral side of the male cylindrical portion 12-2, and extends from the female cylindrical portion 14-1 to the distal end side and has an inner diameter on the peripheral surface of the male tapered portion 12-3. The female taper portion 14-2, which gradually becomes smaller, the female small-diameter claw 14-3 located at the distal end of the female taper portion 14-2, and turned toward the one end side so as to be folded outward from the female small-diameter claw 14-3. Female return portion 14-4 extending obliquely outward, a female knob portion 14-5 formed at one end of the female return portion 14-4, and a female swelling portion bulging inward of the female knob portion 14-5. 14-6.

なお、メス先細り部１４−２、メス小径爪１４−３、メス返し部１４−４、メスつまみ部１４−５、メス膨出部１４−６は、全周ではなく周方向において対向する２箇所に設けられ、両者の間は切除されている。また、メス端部１５は、解放円形リングの他端が接続される部材であって、メス筒部１４−１と一体化されている。   In addition, the female taper portion 14-2, the female small-diameter claw 14-3, the female return portion 14-4, the female knob portion 14-5, and the female swelling portion 14-6 are opposed to each other in the circumferential direction but not in the entire circumference. , And the space between them is cut off. The female end 15 is a member to which the other end of the release circular ring is connected, and is integrated with the female cylindrical portion 14-1.

なお、オス部材１２、メス部材１４、特に弾性変形するメス部材１４は樹脂製とすることが好適であり、各種の樹脂を使用することができる。   The male member 12, the female member 14, and particularly the elastically deformable female member 14, are preferably made of resin, and various resins can be used.

図１（ａ）は、ロック状態を示しており、メス筒部１４−１、メス先細り部１４−２、メス小径爪１４−３が、オス円筒部１２−２、オス先細り部１２−３、オス小径部１２−４の外周側に位置する。メス筒部１４−１の一端側は、オス基部１２−１の先端側端面に当接し、メス小径爪１４−３の先端側端面は、オス先端円筒部１２−５の一端側端面に当接する。   FIG. 1A shows a locked state, in which a female cylinder portion 14-1, a female tapered portion 14-2, and a female small-diameter claw 14-3 are provided with a male cylindrical portion 12-2, a male tapered portion 12-3, It is located on the outer peripheral side of the male small diameter portion 12-4. One end of the female cylindrical portion 14-1 contacts the distal end surface of the male base portion 12-1, and the distal end surface of the female small-diameter claw 14-3 contacts the one end surface of the male cylindrical portion 12-5. .

ここで、オス小径部１２−４（メス小径爪１４−３）の半径に対し、オス先端円筒部１２−５の半径が、αだけ大きく、このαがメス小径爪１４−３の先端を受け止めるかかり代となる。   Here, the radius of the male tip cylindrical portion 12-5 is larger than the radius of the male small diameter portion 12-4 (female small diameter claw 14-3) by α, and this α receives the tip of the female small diameter claw 14-3. It becomes a cost.

図１（ｂ）は、一対のメスつまみ部１４−５を指などでつまんで、内方に向けて押圧した状態を示している。メスつまみ部１４−５が押圧（押圧力Ｆ）によって内側に向けて移動することで、支点Ｐを中心として、メス返し部１４−４が垂直面内で回転して、メス小径爪１４−３が外側に移動する。   FIG. 1B shows a state in which the pair of female knobs 14-5 are pinched by a finger or the like and pressed inward. When the knife knob 14-5 moves inward by pressing (pressing force F), the knife return portion 14-4 rotates in a vertical plane about the fulcrum P, and the knife small-diameter nail 14-3. Moves outward.

これによって、メス先細り部１４−２も外側に拡がり、最も内側の位置がオス先端円筒部１２−５の外形と同一またはそれより外方に至る。すなわち、両者の間隔Ｂが０以上となる。これによって、メス部材１４とオス部材１２のロックが解除され、両者を容易に離隔することができる。   As a result, the female tapered portion 14-2 also spreads outward, and the innermost position is the same as or outside the outer shape of the male tip cylindrical portion 12-5. That is, the interval B between them becomes 0 or more. Thereby, the lock of the female member 14 and the male member 12 is released, and both can be easily separated.

ここで、本実施形態においては、メス膨出部１４−６を有している。このメス膨出部１４−６は、メスつまみ部１４−５を内方に移動した場合に、このメス膨出部１４−６がメス筒部１４−１の外周面にぶつかる。従って、このメス膨出部１４−６がメスつまみ部１４−５およびメス返し部１４−４の内側への移動のストッパになり、それ以上内方には移動しない。この位置は、間隔Ｂが０以上の所定値となるように設定されている。すなわち、オス部材１２とメス部材１４の相対移動のためには、間隔Ｂが０以上であればよくそれ以上離れる必要はない。従って、メス返し部１４−４が塑性変形しない範囲で適切な範囲、例えばＢが数ｍｍ以上にならないようにメス膨出部１４−６の大きさが設定される。これによって、メス返し部１４−４が塑性変形してロック機能が失われることを効果的に防止できる。   Here, in the present embodiment, the swelling portion 14-6 is provided. When the knife knob 14-5 moves inward, the knife bulge 14-6 hits the outer peripheral surface of the knife cylinder 14-1. Therefore, the knife swelling portion 14-6 serves as a stopper for the inward movement of the knife knob 14-5 and the knife return portion 14-4, and does not move any further inward. This position is set so that the interval B has a predetermined value of 0 or more. That is, in order for the male member 12 and the female member 14 to move relative to each other, it is sufficient that the interval B is equal to or greater than 0, and it is not necessary to further separate. Therefore, the size of the female swelling portion 14-6 is set so that the female return portion 14-4 does not become plastically deformed. This effectively prevents the female return portion 14-4 from being plastically deformed and losing the lock function.

図１（ｃ）は、オス部材１２とメス部材１４が離れた状態で、メス部材１４（メスつまみ部１４−５）への押圧を解除した（メスつまみ部１４-５から指を離した）状態を示している。押圧を解除することによって、メス小径爪１４−３およびメス先細り部１４−２は元の位置に戻ろうとするが、そこにはオス先端円筒部１２−５が位置しており、この表面に当たって、それ以上内方には移動できない。そこで、メス部材１４はその状態に留まる。なお、メスつまみ部１４-５も元の位置に戻ろうとするが、元の位置に比べて若干内方の位置に留まる。   FIG. 1C illustrates a state in which the male member 12 and the female member 14 are separated from each other, and the pressing on the female member 14 (the female knob 14-5) is released (the finger is released from the female knob 14-5). The state is shown. By releasing the pressing, the female small-diameter claw 14-3 and the female tapered portion 14-2 try to return to their original positions, but the male tip cylindrical portion 12-5 is located there, and hits this surface. You cannot move further inward. Therefore, the female member 14 remains in that state. The female knob 14-5 also attempts to return to the original position, but remains at a position slightly inward from the original position.

図２には、ロック機構１０を側方から見た図を示してある。メス筒部１４−１は、接続部１６によって、メス端部１５と接続されており、これによってメス部材１４が解放円形リングの他端と接続される。   FIG. 2 shows the lock mechanism 10 as viewed from the side. The female cylinder portion 14-1 is connected to the female end portion 15 by a connection portion 16, whereby the female member 14 is connected to the other end of the release circular ring.

メス返し部１４−４、メスつまみ部１４−５は円周方向に一部のみに形成され、メス先細り部１４−２、メス膨出部１４−６も同様である。なお、メスつまみ部１４−５の内方への押圧時に、メス先細り部１４−２が外方に向けて容易に移動できれば、他の構造でもよい。例えば、メス先細り部１４−２を弾性の大きな材料で接続したり、メス先細り部１４−２を円筒状として軸方向の切り欠き形成することなどでもよい。   The knife return portion 14-4 and the knife knob portion 14-5 are formed only partially in the circumferential direction, and the same applies to the knife taper portion 14-2 and the knife swelling portion 14-6. Note that other structures may be used as long as the tapered portion 14-2 can be easily moved outward when the knife knob 14-5 is pressed inward. For example, the female tapered portion 14-2 may be connected with a material having a large elasticity, or the female tapered portion 14-2 may be formed in a cylindrical shape and cut out in the axial direction.

図３には、ロック機構１０を図２の左側から見た図を示してある。このように、メス返し部１４−４の一部とメスつまみ部１４−５が接続部１６の両側に突出するような構成となっている。   FIG. 3 shows the lock mechanism 10 as viewed from the left side of FIG. In this manner, the configuration is such that a part of the female return portion 14-4 and the female knob portion 14-5 project to both sides of the connection portion 16.

「比較例の構成」
図４は、比較例に係るロック機構の構成及び動作を示す図であり、（ａ）はロック時、（ｂ）はロック解除動作（押圧）時、（ｃ）はロック解除（非押圧）時の状態を示す。 "Configuration of Comparative Example"
4A and 4B are diagrams illustrating a configuration and an operation of a lock mechanism according to a comparative example, in which FIG. 4A illustrates a locked state, FIG. 4B illustrates an unlocked operation (pressed), and FIG. The state of is shown.

図４（ａ）に示すように、この比較例では、メス膨出部１４−６が存在しない。また、メス筒部１４−１、オス円筒部１２−２が短く、従ってメス返し部１４−４がこれらを越えて軸方向に伸びている。このため、図４（ｂ）に示すように、メスつまみ部１４−５を内方に押圧した場合に、メスつまみ部１４−５は、図４（ｂ）の状態からさらに内方に移動することができる。   As shown in FIG. 4A, in this comparative example, the female swelling portion 14-6 does not exist. In addition, the female cylinder 14-1 and the male cylinder 12-2 are short, so that the female return portion 14-4 extends beyond them in the axial direction. Therefore, as shown in FIG. 4B, when the knife knob 14-5 is pressed inward, the knife knob 14-5 moves further inward from the state of FIG. 4B. be able to.

そして、変形量が大きくなると、メス部材１４が塑性変形する可能性があり、この場合にはメス部材１４が変形した状態から復帰できなくなる。すなわち、図４（ｃ）に示すように、メスつまみ部１４−５への押圧力を解除した後も、メス小径爪１４−３は、オス先端円筒部１２−５の外周より外側に位置し、ロック機能が失われてしまう。   When the amount of deformation increases, the female member 14 may be plastically deformed. In this case, the female member 14 cannot be returned from the deformed state. That is, as shown in FIG. 4 (c), even after the pressing force on the female knob 14-5 is released, the female small-diameter claw 14-3 is located outside the outer periphery of the male tip cylindrical portion 12-5. However, the lock function is lost.

上述した実施形態に係るロック機構１０によれば、メス膨出部１４−６が存在し、またメス筒部１４−１、オス円筒部１２−２がメス膨出部１４−６を受け止めるように軸方向に延長されている。従って、メス部材１４の変形量を所定量に抑制して、塑性変形することを防止することができる。   According to the lock mechanism 10 according to the above-described embodiment, the female swelling portion 14-6 exists, and the female cylinder portion 14-1 and the male cylindrical portion 12-2 receive the female swelling portion 14-6. It is extended in the axial direction. Therefore, the amount of deformation of the female member 14 can be suppressed to a predetermined amount, and plastic deformation can be prevented.

「ホースクランプ」
図５には、実施形態に係るロック機構１０をホースクランプに適用した場合の模式図が示してある。ホースクランプ２０は、一部が切除された解放円形リング２２を含む。そして、切除部の両側から外方に向けて一対の係合部２４，２６が形成され、これら係合部２４，２６にロック機構１０のオス部材１２、メス部材１４がそれぞれ接続される。 "Hose clamp"
FIG. 5 is a schematic diagram illustrating a case where the lock mechanism 10 according to the embodiment is applied to a hose clamp. The hose clamp 20 includes a partially cut open circular ring 22. Then, a pair of engaging portions 24 and 26 are formed outward from both sides of the cut portion, and the male member 12 and the female member 14 of the lock mechanism 10 are connected to these engaging portions 24 and 26, respectively.

「他の実施形態」
図６は、他の実施形態に係るロック機構の構成を示す。この例では、メス膨出部１４−６が、メスつまみ部１４−５の内方ではなく、メス筒部１４−１の外周に設けられている。この構成によっても、メス膨出部１４−６がメス部材１４の変形に対するストッパとして機能し、メス部材１４の塑性変形を防止することができる。 "Other embodiments"
FIG. 6 shows a configuration of a lock mechanism according to another embodiment. In this example, the knife swelling portion 14-6 is provided not on the inside of the knife knob 14-5 but on the outer periphery of the knife cylinder portion 14-1. Also according to this configuration, the female swelling portion 14-6 functions as a stopper against deformation of the female member 14, and plastic deformation of the female member 14 can be prevented.
