次に、室内側ハンドル１を操作した時の本実施の形態に係るアンチパニック式錠の作用について説明する。 Next, the operation of the anti-panic lock according to the present embodiment when the indoor handle 1 is operated will be described.
先ず、操作部４を押圧操作しない場合、図２及び図３に示すように、圧縮バネ３の付勢力により、操作部４及びシャフト２が最も室内側にスライドし、各被動部６の内側端部が作用部５の第１係合部３２に係合すると共に、各被動部６の外側端部がストッパー部材３６の各係止凹部３８に係止することにより、室内側ハンドル１の回動が規制される。このように操作部４を押圧操作しない場合には室内側ハンドル１を回動させることができないため、幼い子供等が勝手に室外に出てしまうのを防止することができ、防犯性の向上を図ることができる。 First, when the operation unit 4 is not pressed, the operation unit 4 and the shaft 2 are slid most indoors by the biasing force of the compression spring 3 as shown in FIGS. And the outer end of each driven portion 6 engages with each engaging recess 38 of the stopper member 36, thereby rotating the indoor handle 1. Is regulated. Thus, since the indoor handle 1 cannot be rotated when the operation unit 4 is not pressed, it is possible to prevent a young child or the like from going out of the room without permission and to improve crime prevention. Can be planned.
これに対して、圧縮バネ３の付勢力に抗して操作部４を押圧操作すると、操作部４及びシャフト２が室外側にスライドし、各被動部６の内側端部が第１係合部３２から離間して第２係合部３３の上方又は下方に移動する。したがって、この状態で、室内側ハンドル１を回動させると、係止凹部３８の傾斜部４４が被動部６の外側端部に当接して被動部６を内側に押し込むため、被動部６は第２係合部３３に係合し、回動軸部１０の外周面より外方に突出しなくなる。これにより、各被動部６の外側端部とストッパー部材３６の各係止凹部３８との係止状態が解除され、室内側ハンドル１の回動が許容される。したがって、操作部４を押圧操作しながら室内側ハンドル１を回動させると、前記錠前機構部により室内側ハンドル１の回動力が前記ラッチ部材の扉の小口からの後退動に変換され、扉を解錠することができる。 On the other hand, when the operation portion 4 is pressed against the urging force of the compression spring 3, the operation portion 4 and the shaft 2 slide to the outdoor side, and the inner end portion of each driven portion 6 is the first engagement portion. It moves away from 32 and above or below the second engagement portion 33. Therefore, when the indoor handle 1 is rotated in this state, the inclined portion 44 of the locking recess 38 comes into contact with the outer end portion of the driven portion 6 and pushes the driven portion 6 inward, so that the driven portion 6 2 engages with the engaging portion 33 and does not protrude outward from the outer peripheral surface of the rotating shaft portion 10. Accordingly, the locked state between the outer end of each driven portion 6 and each locking recess 38 of the stopper member 36 is released, and the rotation of the indoor handle 1 is allowed. Therefore, when the indoor handle 1 is rotated while pressing the operating portion 4, the locking mechanism converts the turning force of the indoor handle 1 into the backward movement of the latch member from the small edge of the door. Can be unlocked.

次に、室内側ハンドル１を操作した時の本実施の形態に係るアンチパニック式錠の作用について説明する。 Next, the operation of the anti-panic lock according to the present embodiment when the indoor handle 1 is operated will be described.
先ず、操作部４を押圧操作しない場合、図４に示すように、圧縮バネ３の付勢力により、操作部４及びシャフト２が最も室内側にスライドし、各被動部６１の内側部分６５の内側端部が作用部６０の第１係合部６２に係合して内側部分６５は回動軸部１０の第２外周部１７の外周面１７ａより内方の被動部収容孔１４内に移動すると共に、各被動部６１の外側部分６６の外側端部が第２外周部１７の外周面１７ａより外方に突出してストッパー部材６８の各係止凹部７０に係止した状態に保持される。この時、各被動部６１の内側部分６５と外側部分６６との境界面６１ａが第２外周部１７の外周面１７ａより内方に位置し、境界面６１ａと外周面１７ａとが一致しないため、被動部６１外側部分６６によって室内側ハンドル１の回動が規制される。このように操作部４を押圧操作しない場合には室内側ハンドル１を回動させることができないため、幼い子供等が勝手に室外に出てしまうのを防止することができ、防犯性の向上を図ることができる。 First, when the operation unit 4 is not pressed, the operation unit 4 and the shaft 2 slide to the innermost side by the urging force of the compression spring 3 as shown in FIG. The end portion engages with the first engaging portion 62 of the action portion 60, and the inner portion 65 moves into the driven portion receiving hole 14 inward from the outer peripheral surface 17 a of the second outer peripheral portion 17 of the rotating shaft portion 10. At the same time, the outer end portion of the outer portion 66 of each driven portion 61 protrudes outward from the outer peripheral surface 17 a of the second outer peripheral portion 17, and is held in a state of being locked to each locking recess 70 of the stopper member 68. At this time, the boundary surface 61a between the inner portion 65 and the outer portion 66 of each driven portion 61 is located inward from the outer peripheral surface 17a of the second outer peripheral portion 17, and the boundary surface 61a and the outer peripheral surface 17a do not match. The rotation of the indoor handle 1 is restricted by the outer portion 66 of the driven portion 61. Thus, since the indoor handle 1 cannot be rotated when the operation unit 4 is not pressed, it is possible to prevent a young child or the like from going out of the room without permission and to improve crime prevention. Can be planned.
これに対して、圧縮バネ３の付勢力に抗して操作部４を押圧操作すると、図５に示すように、操作部４及びシャフト２が室外側にスライドし、各被動部６１の内側部分６５の内側端部が作用部６０の傾斜面６４に沿って摺動して第２係合部６３に係合すると共に、各被動部６１の外側部分６６がバネ７１の付勢力に抗して外方に移動しストッパー部材６８の各係止凹部７０に完全に入り込んだ状態となる。これにより、各被動部６１の内側部分６５と外側部分６６との境界面６１ａが第２外周部１７の外周面１７ａと一致するため、室内側ハンドル１の回動が許容される。したがって、操作部４を押圧操作しながら室内側ハンドル１を回動させると、前記錠前機構部により室内側ハンドル１の回動力が前記ラッチ部材の扉の小口からの後退動に変換され、扉を解錠することができる。 On the other hand, when the operation portion 4 is pressed against the urging force of the compression spring 3, the operation portion 4 and the shaft 2 slide to the outdoor side as shown in FIG. The inner end portion of 65 slides along the inclined surface 64 of the action portion 60 and engages with the second engagement portion 63, and the outer portion 66 of each driven portion 61 resists the biasing force of the spring 71. It moves outward and is completely in the respective locking recesses 70 of the stopper member 68. Thereby, since the boundary surface 61a between the inner portion 65 and the outer portion 66 of each driven portion 61 coincides with the outer peripheral surface 17a of the second outer peripheral portion 17, the rotation of the indoor handle 1 is allowed. Therefore, when the indoor handle 1 is rotated while pressing the operating portion 4, the locking mechanism converts the turning force of the indoor handle 1 into the backward movement of the latch member from the small edge of the door. Can be unlocked.
このように上記した本発明の第１及び第２の実施の形態に係るアンチパニック式錠によれば、室外側からは施錠状態でも操作部４を押圧しながら室内側ハンドル１の把持部９を回動させることによって解錠状態にすることができるため、アンチパニック式錠の本来の機能を確保しつつ、幼い子供等が勝手に室外に出てしまうのを防止することができ、防犯性を高めることができる。 As described above, according to the anti-panic locks according to the first and second embodiments of the present invention described above, the grip portion 9 of the indoor handle 1 is pressed while pressing the operation portion 4 from the outdoor side even in the locked state. Since it can be unlocked by rotating it, it can prevent the child from going out of the room without permission while securing the original function of the anti-panic lock. Can be increased.
また、上記した本発明の第１及び第２の実施の形態に係るアンチパニック式錠では、室内側から扉を解錠させる場合、操作部４を押圧操作する必要があるが、押圧操作自体が簡単な操作であると共に、操作部４が室内側ハンドル１の回動軸部１０の延長上に配設されているため、通常の大人や小学生以上の子供であれば、室内側ハンドル１の把持部９を手で把持する際に親指で簡単に操作部４を押圧操作することができる。したがって、従来のアンチパニック式錠と比べて、室内側からの解錠操作が難しくなることもない。 Further, in the anti-panic locks according to the first and second embodiments of the present invention described above, when the door is unlocked from the indoor side, it is necessary to press the operation unit 4. In addition to simple operation, the operation unit 4 is disposed on the extension of the rotation shaft 10 of the indoor handle 1, so that the normal handle or the child holding the indoor handle 1 can be gripped by children who are more than elementary school children. When gripping the part 9 by hand, the operation part 4 can be easily pressed with the thumb. Therefore, the unlocking operation from the indoor side does not become difficult as compared with the conventional anti-panic lock.
さらに、上記した本発明の第１及び第２の実施の形態に係るアンチパニック式錠では、作用部５，６０と係合する被動部６，６１が、操作部４の押圧操作によるシャフト２のスライド動作に伴って径方向にスライドするように構成されているため、ガタつきのない円滑な解錠動作を実現することができる。 Furthermore, in the anti-panic lock according to the first and second embodiments of the present invention described above, the driven parts 6 and 61 engaged with the action parts 5 and 60 are provided on the shaft 2 by the pressing operation of the operation part 4. Since it is configured to slide in the radial direction along with the sliding operation, a smooth unlocking operation without backlash can be realized.
なお、上記した本発明の第１及び第２の実施の形態の説明は、本発明に係るアンチパニック式錠における好適な実施の形態を説明しているため、技術的に好ましい種々の限定を付している場合もあるが、本発明の技術範囲は、特に本発明を限定する記載がない限り、これらの態様に限定されるものではない。すなわち、上記した本発明の第１及び第２の実施の形態における構成要素は適宜、既存の構成要素等との置き換えが可能であり、かつ、他の既存の構成要素との組合せを含む様々なバリエーションが可能であり、上記した本発明の実施の形態の記載をもって、特許請求の範囲に記載された発明の内容を限定するものではない。 The above description of the first and second embodiments of the present invention describes preferred embodiments of the anti-panic lock according to the present invention, and therefore various technically preferable limitations are attached. However, the technical scope of the present invention is not limited to these embodiments unless specifically described to limit the present invention.
