図５（ａ）〜（ｃ）は、案内機構部１２の施解錠案内部１２ａの構造を示す正面図、Ａ−Ａ線断面図、背面図である。 5A to 5C are a front view, a cross-sectional view taken along line AA, and a rear view showing the structure of the locking / unlocking guide portion 12a of the guide mechanism portion 12. FIG.

図５に示すように、案内機構部１２の施解錠案内部１２ａは、操作ツマミ１１ａを露出状態でスライドさせるツマミスライド用開口部１２ａ１と、操作ツマミ１１ａの左右両側のスライド動作被案内片１１ａ２の上下方向のスライド動作と表裏方向の出入動作を案内するスライド動作案内部１２ａ２が設けられ、そのスライド動作案内部１２ａ２にしたがって操作ツマミ１１ａをスライド動作させて施錠状態と解錠状態とで停止させるものである。また、この案内機構部１２は、操作ツマミ１１ａが施錠位置と解錠位置とにある場合は、操作ツマミ１１ａに上下のスライド方向に外力が加わっても簡単に施解錠が解除することがないように、その施錠位置と解錠位置とにある場合は、操作ツマミ１１ａの左右両側のスライド動作被案内片１１ａ２がスライド動作案内部１２ａ２から外れて、スプリング１１ｂにより操作ツマミ１１ａの表面をツマミスライド用開口部１２ａ１よりも突出させた高位置状態に押し出すように構成されている。これに対し、操作ツマミ１１ａが施錠位置と解錠位置との間をスライド動作する場合は、操作ツマミ１１ａのスライド動作被案内片１１ａ２が案内機構部１２のスライド動作案内部１２ａ２に当接して案内され操作ツマミ１１ａを低位置に引き入れた状態でスライド動作するように構成されている。つまり、この案内機構部１２のスライド動作案内部１２ａ２は、操作ツマミ１１ａがスライド動作中は、操作ツマミ１１ａの左右両側のスライド動作被案内片１１ａ２に当接して操作ツマミ１１ａを低位置に引き入れた状態に移動させて、操作ツマミ１１ａの操作部１１ａ３の表面を本施錠装置１が設けられた召合せ框２１の表面とほぼ平行な状態で案内する。 As shown in FIG. 5, the locking / unlocking guide portion 12a of the guide mechanism portion 12 includes a knob slide opening portion 12a1 for sliding the operation knob 11a in an exposed state, and slide operation guided pieces 11a2 on both the left and right sides of the operation knob 11a. A slide operation guide portion 12a2 is provided for guiding the slide operation in the vertical direction and the entrance / exit operation in the front and back direction, and the operation knob 11a is slid in accordance with the slide operation guide portion 12a2 to stop in the locked state and the unlocked state. It is. In addition, when the operation knob 11a is in the locking position and the unlocking position, the guide mechanism section 12 does not easily unlock and unlock even if an external force is applied to the operation knob 11a in the vertical sliding direction. In addition, when it is in the locked position and the unlocked position, the slide operation guided pieces 11a2 on both the left and right sides of the operation knob 11a are detached from the slide operation guide portion 12a2, and the surface of the operation knob 11a is used for the knob slide by the spring 11b. It is comprised so that it may extrude to the high position state protruded rather than the opening part 12a1. On the other hand, when the operation knob 11a slides between the locked position and the unlocked position, the slide operation guided piece 11a2 of the operation knob 11a abuts on the slide operation guide section 12a2 of the guide mechanism section 12 for guidance. In this state, the operation knob 11a is slid in a state where it is pulled into the low position. That is, the slide operation guide unit 12a2 of the guide mechanism unit 12 is brought into contact with the slide operation guided pieces 11a2 on both the left and right sides of the operation tab 11a while the operation tab 11a is sliding, and pulls the operation tab 11a to a low position. It is moved to the state, and the surface of the operation part 11a3 of the operation knob 11a is guided in a state substantially parallel to the surface of the summoning bowl 21 provided with the locking device 1.

また、案内機構部１２は、そのスライド動作案内部１２ａ２の両側に、少なくとも操作ツマミ１１ａのスライド動作被案内片１１ａ２のスライド動作方向の長さ以上の所定距離、離間した箇所に、操作ツマミ１１ａが施錠位置と解錠位置とにある場合、操作ツマミ１１ａの施錠時傾斜被支持片１１ａ６および解錠時傾斜被支持片１１ａ８に当接して、操作ツマミ１１ａを高位置状態で、かつ、操作ツマミ１１ａの表面におけるツマミスライド用開口部１２ａ１の中央側が高くなるように操作ツマミ１１ａを斜めに支持する施錠時傾斜支持部１２ａ３と解錠時傾斜支持部１２ａ４とが設けられている。 Further, the guide mechanism portion 12 has the operation knob 11a on both sides of the slide operation guide portion 12a2 at a distance of at least a predetermined distance longer than the length of the slide operation guided piece 11a2 of the operation knob 11a. When in the locking position and the unlocking position, the operation knob 11a is brought into contact with the tilted supported piece 11a6 during locking and the tilted supported piece 11a8 during unlocking, so that the operation knob 11a is in the high position and the operation knob 11a. An inclined support portion 12a3 at the time of locking and an inclined support portion 12a4 at the time of unlocking are provided to support the operation knob 11a at an angle so that the center side of the knob slide opening 12a1 on the surface is raised.

そして、この施錠時傾斜支持部１２ａ３および解錠時傾斜支持部１２ａ４は、それぞれ、操作ツマミ１１ａがスライド動作中は操作ツマミ１１ａを低位置に引き入れ、施錠位置および解錠位置では操作ツマミ１１ａを高位置に押し出すように、操作ツマミ１１ａの施錠時傾斜被支持片１１ａ６および解錠時傾斜被支持片１１ａ８を支持する傾斜案内面を有している。ただし、本発明では、施錠時傾斜支持部１２ａ３および解錠時傾斜支持部１２ａ４を設けることや、施錠時傾斜支持部１２ａ３および解錠時傾斜支持部１２ａ４が傾斜案内面を有することは任意であり、施錠時傾斜支持部１２ａ３および解錠時傾斜支持部１２ａ４を省略したり、平行な案内面を有していても勿論良い。なお、傾斜案内面の効果についは後述する。 The tilt support portion 12a3 for locking and the tilt support portion 12a4 for unlocking are respectively drawn into the low position while the operation knob 11a is sliding, and the operation knob 11a is raised in the lock position and the unlock position. In order to push out to the position, the operation knob 11a has an inclined guide surface that supports the inclined supported piece 11a6 when locked and the inclined supported piece 11a8 when unlocked. However, in the present invention, it is optional to provide the inclined support portion 12a3 during locking and the inclined support portion 12a4 during unlocking, and the inclined support portion 12a3 during locking and the inclined support portion 12a4 during unlocking have an inclined guide surface. Of course, the inclined support portion 12a3 at the time of locking and the inclined support portion 12a4 at the time of unlocking may be omitted or a parallel guide surface may be provided. The effect of the inclined guide surface will be described later.

また、案内機構部１２の左右両側に設けられている施錠時傾斜支持部１２ａ３および解錠時傾斜支持部１２ａ４は、図５（ａ），（ｃ）に示すように、案内機構部１２の左右両側に設けられているスライド動作案内部１２ａ２よりも内側への突出量を大きくしている。その理由については後述する。 Further, as shown in FIGS. 5 (a) and 5 (c), the locking tilt support portion 12a3 and the unlocking tilt support portion 12a4 provided on both the left and right sides of the guide mechanism portion 12 are provided on the left and right sides of the guide mechanism portion 12, respectively. The amount of protrusion to the inside is larger than the sliding motion guide portions 12a2 provided on both sides. The reason will be described later.

なお、この施錠装置１では、操作ツマミ１１ａが施錠状態にある場合、スライド部１１の操作ツマミ支持部１１ｃの下端部に設けられたインジケータ１１ｃ４が位置する箇所に報知用開口部１２ａ５が形成されている。なお、図５（ｂ）における１２ａ６，１２ａ７は、それぞれ、後側蓋部１２ｂの掛止部１２ｂ１および掛止部１２ｂ２が掛止される被掛止孔および被掛止部である。 In the locking device 1, when the operation knob 11a is in the locked state, the notification opening 12a5 is formed at a position where the indicator 11c4 provided at the lower end of the operation knob support part 11c of the slide part 11 is located. Yes. In addition, 12a6 and 12a7 in FIG.5 (b) are respectively the to-be-latched hole and the to-be-latched part by which the latching | locking part 12b1 and the latching | locking part 12b2 of the rear side cover part 12b are latched.

図６（ａ）〜（ｃ）は、案内機構部１２の後側蓋部１２ｂの構造を示す正面図、側面図、Ｂ−Ｂ線断面図である。 6A to 6C are a front view, a side view, and a BB line sectional view showing the structure of the rear lid portion 12b of the guide mechanism portion 12. FIG.

図６に示すように、案内機構部１２の後側蓋部１２ｂは、施解錠案内部１２ａとの間で操作ツマミ１１ａや操作ツマミ支持部１１ｃを上下方向にスライド可能な状態で取り付けるもので、施解錠案内部１２ａの被掛止孔１２ａ６や被掛止部１２ａ７に掛止する掛止部１２ｂ１および掛止部１２ｂ２を有している。また、後側蓋部１２ｂは、本施錠装置１を雨戸２の召合せ框２１に取り付けるためのネジ孔１２ｂ３も設けられている。なお、本施錠装置１を召合せ框２１にネジで取り付けた後（図省略）、案内機構部１２の上端に上側蓋部１２ｃを掛止する。 As shown in FIG. 6, the rear lid portion 12b of the guide mechanism portion 12 is attached to the operation knob 11a and the operation knob support portion 11c so as to be slidable in the vertical direction with the locking / unlocking guide portion 12a. It has a latching portion 12b1 and a latching portion 12b2 that latch on the latching hole 12a6 and the latching portion 12a7 of the locking / unlocking guide portion 12a. Further, the rear lid portion 12 b is also provided with a screw hole 12 b 3 for attaching the locking device 1 to the summoning tub 21 of the shutter 2. In addition, after attaching this locking device 1 to the summoning bowl 21 with a screw (not shown), the upper lid portion 12 c is hooked on the upper end of the guide mechanism portion 12.

次に、本実施形態の施錠装置１の動作について、図面を参照して説明する。なお、以下の説明では、下枠３１に設けられたストッパ穴を使用して施錠する下枠３１用の施錠装置１の動作について説明する。 Next, operation | movement of the locking device 1 of this embodiment is demonstrated with reference to drawings. In addition, in the following description, operation | movement of the locking device 1 for the lower frame 31 locked using the stopper hole provided in the lower frame 31 is demonstrated.

図７（ａ），（ｂ）は、操作ツマミ１１ａが施錠状態（ロック状態）にある場合の施錠装置１の正面図、断面図である。 FIGS. 7A and 7B are a front view and a cross-sectional view of the locking device 1 when the operation knob 11a is in a locked state (locked state).

図７（ａ），（ｂ）に示すように、操作ツマミ１１ａが施錠状態にある場合、すなわち図７（ａ），（ｂ）上、ツマミスライド用開口部１２ａ１の下側に位置する場合には、操作ツマミ支持部１１ｃ、連結部材１１ｄおよびストッパ支持部１１ｅの下側に取り付けられたストッパ１１ｆが、下枠３１に設けられたストッパ穴に挿入される。そのため、この施錠装置１が取り付けられた雨戸２は、下枠３１上を移動できず、施錠（ロック）される。なお、本実施形態では連結部材１１ｄとストッパ１１ｆを別部材としているが、連結部材１１ｄをステンレス等の強度が確保できる材質として、連結部材１１ｄの先端部にストッパ１１ｆを設けても（一体としても）よい。 As shown in FIGS. 7A and 7B, when the operation knob 11a is in a locked state, that is, when the operation knob 11a is positioned below the knob slide opening 12a1 in FIGS. 7A and 7B. The stopper 11f attached to the lower side of the operation knob support portion 11c, the connecting member 11d, and the stopper support portion 11e is inserted into a stopper hole provided in the lower frame 31. Therefore, the shutter 2 to which the locking device 1 is attached cannot be moved on the lower frame 31 and is locked (locked). In this embodiment, the connecting member 11d and the stopper 11f are separate members. However, even if the connecting member 11d is made of a material that can ensure the strength, such as stainless steel, the stopper 11f is provided at the tip of the connecting member 11d (even as an integral part). ) Good.

ここで、上述したように、操作ツマミ１１ａの左右両側に設けられている施錠時傾斜被支持片１１ａ６および解錠時傾斜被支持片１１ａ８は、図３（ｂ），（ｄ）に示すように、左右両側に設けられているスライド動作被案内片１１ａ２よりも左右方向への突出量を小さくしている。その一方、案内機構部１２の左右両側に設けられている施錠時傾斜支持部１２ａ３および解錠時傾斜支持部１２ａ４は、図５（ａ），（ｃ）に示すように、左右両側に設けられているスライド動作案内部１２ａ２よりも内側への突出量を大きくしている。その結果、操作ツマミ１１ａの左右両側のスライド動作被案内片１１ａ２は、スライド動作時は、案内機構部１２の左右両側のスライド動作案内部１２ａ２のみに当接する。これに対し、操作ツマミ１１ａの左右両側に設けられている施錠時傾斜被支持片１１ａ６および解錠時傾斜被支持片１１ａ８は、操作ツマミ１１ａが高位置に突出した状態では、施錠時傾斜支持部１２ａ３および解錠時傾斜支持部１２ａ４の上下両端面に当接するものの、スライド動作案内部１２ａ２の間を通り抜けることができる。 Here, as described above, the locking-inclined supported pieces 11a6 and the unlocked-inclined supported pieces 11a8 provided on the left and right sides of the operation knob 11a are as shown in FIGS. 3 (b) and 3 (d). The amount of protrusion in the left-right direction is smaller than the sliding motion guided piece 11a2 provided on both the left and right sides. On the other hand, the locking tilt support 12a3 and the unlocking tilt support 12a4 provided on the left and right sides of the guide mechanism 12 are provided on the left and right sides as shown in FIGS. 5 (a) and 5 (c). The amount of inward protrusion is larger than the sliding motion guide portion 12a2. As a result, the slide operation guided pieces 11a2 on the left and right sides of the operation knob 11a abut on only the slide operation guide portions 12a2 on the left and right sides of the guide mechanism unit 12 during the slide operation. On the other hand, when the operation knob 11a protrudes to a high position, the lockable inclined supported piece 11a6 and the unlocked inclined supported piece 11a8 provided on the left and right sides of the operation knob 11a are inclined support portions when locked. 12a3 and the unlocking inclined support portion 12a4 are in contact with the upper and lower end surfaces, but can pass between the sliding motion guide portions 12a2.

そのため、この施錠状態の際は、図７（ａ），（ｂ）に示すように、操作ツマミ１１ａのスライド動作被案内片１１ａ２は、スライド動作案内部１２ａ２と施錠時傾斜支持部１２ａ３との間に位置してツマミスライド用開口部１２ａ１の周縁裏面に当接する。また、左右のスライド動作案内部１２ａ２の間を通り抜けた解錠時傾斜被支持片１１ａ８もツマミスライド用開口部１２ａ１の周縁裏面に当接する。これに対し、操作ツマミ１１ａの施錠時傾斜被支持片１１ａ６は、図７（ａ），（ｂ）に示すように、施解錠案内部１２ａの施錠時傾斜支持部１２ａ３に当接して支持および案内される。 Therefore, in this locked state, as shown in FIGS. 7A and 7B, the slide operation guided piece 11a2 of the operation knob 11a is located between the slide operation guide portion 12a2 and the inclined support portion 12a3 when locked. And is in contact with the rear surface of the periphery of the knob slide opening 12a1. Further, the unlocked inclined supported piece 11a8 that passes between the left and right sliding operation guide portions 12a2 also comes into contact with the rear surface of the peripheral edge of the knob slide opening 12a1. On the other hand, as shown in FIGS. 7A and 7B, the tilted supported piece 11a6 at the time of locking of the operation knob 11a abuts on the tilted support portion 12a3 at the time of locking and unlocks and supports and guides. Is done.

その結果、操作ツマミ１１ａは、図７（ｂ）に示すように、施解錠案内部１２ａによってツマミスライド用開口部１２ａ１の中央部側、すなわち図上、上側が高くなるように斜めに支持される。この際、操作ツマミ１１ａの施錠時傾斜状態保持面１１ａ５がツマミスライド用開口部１２ａ１の下部周縁の裏面側に潜り込み、場合によっては、ツマミスライド用開口部１２ａ１の下部周縁の裏面に当接する。なお、本発明では、操作ツマミ１１ａに施錠時傾斜状態保持面１１ａ５を設けることは必須でないので、施錠時に操作ツマミ１１ａの施錠時傾斜状態保持面１１ａ５がツマミスライド用開口部１２ａ１の下部周縁の裏面側に潜り込んだり、ツマミスライド用開口部１２ａ１の下部周縁の裏面に当接することは任意である。 As a result, as shown in FIG. 7B, the operation knob 11a is supported diagonally by the locking / unlocking guide part 12a so that the center part side of the knob slide opening part 12a1, that is, the upper side in the figure becomes higher. . At this time, the locked state holding surface 11a5 at the time of locking of the operation knob 11a sinks into the back surface side of the lower periphery of the knob slide opening 12a1, and in some cases, abuts on the back surface of the lower periphery of the knob slide opening 12a1. In the present invention, since it is not essential to provide a locking time inclined state holding surface 11a 5 to the operation knob 11a, the operation knob 11a at locking when locking inclined state holding surface 11a5 of the bottom peripheral edge of the knob the slide opening 12a1 It is optional to sink into the back surface side or to contact the back surface of the lower peripheral edge of the knob slide opening 12a1.

従って、この施錠装置１によれば、施錠時には、操作ツマミ１１ａの表面がツマミスライド用開口部１２ａ１の中央部側、すなわち図７上、上側が高くなるように斜めに支持されるため、その施錠状態から解錠状態に移行、すなわち図７上、操作ツマミ１１ａを押して上方向に移動させる場合に、操作ツマミ１１ａが傾斜せずに平行な状態にある場合よりも、ユーザの指が操作ツマミ１１ａの表面に引っ掛かり易くなり、子供や高齢者などが使用する場合であっても使用勝手が向上したユニバーサルデザインな戸の施錠装置を提供することができる。 Therefore, according to the locking device 1, when locking, the surface of the operation knob 11a is supported obliquely so that the center side of the knob slide opening 12a1, that is, the upper side in FIG. When the operation knob 11a is shifted from the state to the unlocked state, that is, when the operation knob 11a is pushed and moved upward in FIG. 7, the user's finger moves to the operation knob 11a more than when the operation knob 11a is in a parallel state without being inclined. Therefore, it is possible to provide a universally designed door locking device with improved usability even when used by children or elderly people.

また、この施錠時に、操作ツマミ１１ａを押さずにスライド動作方向の上方向へ外力が加わり、その施錠状態から解錠状態に移行させようとしても、図７（ｂ）に示すように、操作ツマミ本体１１ａ１の左右両側に設けられたスライド動作被案内片１１ａ２の上端部が、施解錠案内部１２ａのスライド案内部１２ａ２の下端部に当接して移動しない。そのため、操作ツマミ１１ａが押されずに単に上方向の力が加わっても、簡単に施錠状態が解除されることを防止できるので、施錠状態を確実に保持することができる。 In addition, even when an external force is applied upward in the sliding operation direction without pressing the operation knob 11a at the time of locking, even if an attempt is made to shift from the locked state to the unlocked state, as shown in FIG. The upper end portions of the slide operation guided pieces 11a2 provided on the left and right sides of the main body 11a1 are in contact with the lower end portions of the slide guide portions 12a2 of the locking / unlocking guide portions 12a and do not move. Therefore, even if an upward force is simply applied without pressing the operation knob 11a, the locked state can be easily prevented from being released, so that the locked state can be reliably maintained.

また、施解錠案内部１２ａの施錠時傾斜支持部１２ａ３は、図７（ａ），（ｂ）に示すように、その傾斜した傾斜案内面が操作ツマミ１１ａの施錠時傾斜被支持片１１ａ６に当接しているが、施錠時傾斜支持部１２ａ３が傾斜案内面を有することで施錠時傾斜被支持片１１ａ６が面ではなく線で当接し、施錠時傾斜被支持片１１ａ６が、施錠時傾斜支持部１２ａ３に当接し始めてから図７（ａ），（ｂ）の位置に達するまで移動する際の摩擦抵抗を減らしている。そのため、操作ツマミ１１ａを施錠位置へ向けてスライド動作する場合は、操作ツマミ１１ａを確実に施錠位置に案内することができ、この点でも、子供や高齢者などが使用する場合であっても使用勝手が向上したユニバーサルデザインな戸の施錠装置１を提供することができる。 Further, as shown in FIGS. 7A and 7B, the inclined support portion 12a3 for locking of the locking / unlocking guide portion 12a has an inclined inclined guide surface that contacts the inclined supported piece 11a6 for locking of the operation knob 11a. In contact with each other, the inclined support portion 12a3 at the time of locking has an inclined guide surface, so that the inclined supported piece 11a6 at the time of locking comes into contact with a line instead of a surface, and the inclined supported piece 11a6 at the time of locking is inclined support portion 12a3 at the time of locking The frictional resistance at the time of moving until it reaches the position shown in FIGS. Therefore, when the operation knob 11a is slid toward the locking position, the operation knob 11a can be reliably guided to the locking position, and in this respect, even when used by children, elderly people, etc. It is possible to provide a universally designed door locking device 1 with improved usability.

また、この施錠装置１では、操作ツマミ１１ａが施錠状態にある場合、スライド部１１の操作ツマミ支持部１１ｃの下端部に設けられた緑色等によりこの施錠装置１が施錠状態にあることを示すインジケータ１１ｃ４が、案内機構部１２の施解錠案内部１２ａの下端部に設けられた報知用開口部１２ａ５の位置にくるので、ユーザは、報知用開口部１２ａ５に現れたインジケータ１１ｃ４の緑色等によりこの施錠装置１が施錠（ロック）状態にあることを認識できる。その結果、この点でも、子供や高齢者などが使用する場合であっても使用勝手が向上したユニバーサルデザインな戸の施錠装置１を提供することができる。 Moreover, in this locking device 1, when the operation knob 11a is in the locked state, an indicator that indicates that the locking device 1 is in the locked state by green or the like provided at the lower end portion of the operation knob supporting portion 11c of the slide portion 11 Since 11c4 comes to the position of the notification opening 12a5 provided at the lower end of the locking / unlocking guide portion 12a of the guide mechanism portion 12, the user can lock the lock by the green color of the indicator 11c4 appearing in the notification opening 12a5. It can be recognized that the device 1 is in a locked (locked) state. As a result, also in this respect, it is possible to provide the universal design door locking device 1 with improved usability even when used by children, elderly people, and the like.

図９（ａ），（ｂ）に示すように、操作ツマミ１１ａが解錠状態にある場合、すなわち図９（ａ），（ｂ）上、ツマミスライド用開口部１２ａ１の上側に位置する場合には、操作ツマミ支持部１１ｃ、連結部材１１ｄおよびストッパ支持部１１ｅの下側に取り付けられたストッパ１１ｆ（図７参照。）が、下枠３１に設けられたストッパ穴から飛び出す。そのため、この施錠装置１が取り付けられた雨戸２は、解錠され、下枠３１上を移動できる。 As shown in FIGS. 9A and 9B, when the operation knob 11a is in an unlocked state, that is, when it is positioned above the knob slide opening 12a1 in FIGS. 9A and 9B. The stopper 11f (see FIG. 7) attached to the lower side of the operation knob support portion 11c, the connecting member 11d, and the stopper support portion 11e pops out from the stopper hole provided in the lower frame 31. Therefore, the shutter 2 to which the locking device 1 is attached is unlocked and can move on the lower frame 31.

その解錠状態の際、図９（ａ），（ｂ）に示すように、操作ツマミ１１ａのスライド動作被案内片１１ａ２は、スライド動作案内部１２ａ２と解錠時傾斜支持部１２ａ４との間に位置してツマミスライド用開口部１２ａ１の周縁裏面に当接する。また、左右のスライド動作案内部１２ａ２の間を通り抜けた施錠時傾斜被支持片１１ａ６もツマミスライド用開口部１２ａ１の周縁裏面に当接する。これに対し、操作ツマミ１１ａの解錠時傾斜被支持片１１ａ８は、図９（ａ），（ｂ）に示すように、施解錠案内部１２ａの解錠時傾斜支持部１２ａ４に当接して支持および案内される。 In the unlocked state, as shown in FIGS. 9A and 9B, the slide motion guided piece 11a2 of the operation knob 11a is located between the slide motion guide portion 12a2 and the unlocked inclined support portion 12a4. It is located and abuts against the peripheral back surface of the knob slide opening 12a1. In addition, the locked inclined supported piece 11a6 that has passed through between the left and right sliding motion guide portions 12a2 also comes into contact with the peripheral back surface of the knob slide opening 12a1. On the other hand, the unlocked inclined supported piece 11a8 of the operation knob 11a is supported in contact with the unlocked inclined support portion 12a4 of the locking / unlocking guide portion 12a as shown in FIGS. 9 (a) and 9 (b). And guided.

その結果、操作ツマミ１１ａは、図９（ｂ）に示すように、施解錠案内部１２ａによってツマミスライド用開口部１２ａ１の中央部側、すなわち図上、下側が高くなるように斜めに支持される。この際、操作ツマミ１１ａの解錠時傾斜状態保持面１１ａ７がツマミスライド用開口部１２ａ１の上部周縁の裏面側に潜り込み、場合によっては、ツマミスライド用開口部１２ａ１の上部周縁の裏面に当接する。なお、本発明では、操作ツマミ１１ａに解錠時傾斜状態保持面１１ａ７を設けることは必須でないので、解錠時に操作ツマミ１１ａの解錠時傾斜状態保持面１１ａ７がツマミスライド用開口部１２ａ１の上部周縁の裏面側に潜り込んだり、ツマミスライド用開口部１２ａ１の上部周縁の裏面に当接することは任意である。
As a result, as shown in FIG. 9B, the operation knob 11a is supported diagonally by the locking / unlocking guide part 12a so that the center part side of the knob slide opening part 12a1, that is, the lower side in the figure becomes higher. . At this time, the unlocked inclined state holding surface 11a7 of the operation knob 11a sinks into the back surface side of the upper periphery of the knob slide opening 12a1, and in some cases, contacts the back surface of the upper periphery of the knob slide opening 12a1. In the present invention, since it is not essential to provide the operation knob 11a with the unlocked inclined state holding surface 11a7, the unlocked inclined state holding surface 11a7 of the operation knob 11a is unlocked with the knob slide opening 12a1 when unlocked. It is arbitrary to sink into the back surface side of the upper peripheral edge or to contact the rear surface of the upper peripheral edge of the knob slide opening 12a1.

従って、この施錠装置１によれば、解錠時にも、操作ツマミ１１ａの表面がツマミスライド用開口部１２ａ１の中央部側、すなわち図９上、下側が高くなるように斜めに支持されるため、その解錠状態から施錠状態に移行、すなわち図９上、操作ツマミ１１ａを押して下方向に移動させる場合に、操作ツマミ１１ａが傾斜せずに平行な状態にある場合よりも、ユーザの指が操作ツマミ１１ａの表面に引っ掛かり易くなり、子供や高齢者などが使用する場合であっても使用勝手が向上したユニバーサルデザインな戸の施錠装置を提供することができる。 Therefore, according to this locking device 1, even when unlocking, the surface of the operation knob 11a is supported obliquely so that the center side of the knob slide opening 12a1, that is, the lower side in FIG. When the operation knob 11a is shifted from the unlocked state to the locked state, that is, when the operation knob 11a is moved downward in FIG. 9, the user's finger is operated more than when the operation knob 11a is in a parallel state without being inclined. It is easy to get caught on the surface of the knob 11a, and it is possible to provide a universal design door locking device with improved usability even when used by children or elderly people.

また、この解錠時に、操作ツマミ１１ａを押さずにスライド動作方向に外力が加わり、その解錠状態から施錠状態に移行させようとしても、図９（ｂ）に示すように、操作ツマミ本体１１ａ１の左右両側に設けられたスライド動作被案内片１１ａ２の下端部が、施解錠案内部１２ａのスライド案内部１２ａ２の上端部に当接して移動しない。そのため、操作ツマミ１１ａが押されずに単に下方向の力が加わっても、簡単に解錠状態が解除されることを防止できるので、解錠状態を確実に保持することができる。 Further, when the unlocking operation is performed, an external force is applied in the sliding operation direction without pressing the operation knob 11a, and the operation knob main body 11a1 is moved from the unlocked state to the locked state as shown in FIG. 9B. The lower end portions of the slide operation guided pieces 11a2 provided on both the left and right sides of the sliding contact portion 12a2 do not move due to contact with the upper end portions of the slide guide portions 12a2 of the locking / unlocking guide portion 12a. Therefore, even if a downward force is simply applied without pressing the operation knob 11a, the unlocked state can be prevented from being easily released, and thus the unlocked state can be reliably held.

また、施解錠案内部１２ａの解錠時傾斜支持部１２ａ４は、図９（ａ），（ｂ）に示すように、その傾斜した傾斜案内面が操作ツマミ１１ａの解錠時傾斜被支持片１１ａ８に当接しているが、解錠時傾斜支持部１２ａ４が傾斜案内面を有することで解錠時傾斜被支持片１１ａ８が面ではなく線で当接し、解錠時傾斜被支持片１１ａ８が、解錠時傾斜支持部１２ａ４に当接し始めてから図９（ａ），（ｂ）の位置に達するまで移動する際の摩擦抵抗を減らしている。そのため、操作ツマミ１１ａを解錠位置へ向けてスライド動作する場合は、操作ツマミ１１ａを確実に解錠位置に案内することができ、この点でも、子供や高齢者などが使用．０する場合であっても使用勝手を向上させたユニバーサルデザインな戸の施錠装置１を提供することができる。 Further, as shown in FIGS. 9 (a) and 9 (b), the inclined support portion 12a4 for unlocking / unlocking guide portion 12a has an inclined inclined guide surface whose inclined support surface 11a8 is for unlocking operation knob 11a. However, when the unlocked inclined support portion 12a4 has the inclined guide surface, the unlocked inclined supported piece 11a8 comes into contact with a line instead of the surface, and the unlocked inclined supported piece 11a8 is unlocked. The frictional resistance at the time of moving until it reaches the position of FIG. 9 (a), (b) after it starts to contact | abut to the lock | rock inclination support part 12a4 is reduced. Therefore, when the operation knob 11a is slid toward the unlocking position, the operation knob 11a can be surely guided to the unlocking position, and this point is also used by children and elderly people. Even in the case of zero, the universal design door locking device 1 with improved usability can be provided.

また、この施錠装置１では、操作ツマミ１１ａが解錠状態にある場合、スライド部１１の操作ツマミ支持部１１ｃの下端部に設けられたインジケータ１１ｃ４は、案内機構部１２の施解錠案内部１２ａに隠れ、報知用開口部１２ａ５からは見えない。そのため、ユーザは解錠状態にあることを認識できる。 Further, in this locking device 1, when the operation knob 11 a is in the unlocked state, the indicator 11 c 4 provided at the lower end of the operation knob support part 11 c of the slide part 11 is connected to the locking / unlocking guide part 12 a of the guide mechanism part 12. It is hidden and not visible from the notification opening 12a5. Therefore, the user can recognize that it is in an unlocked state.

また、本実施形態の施錠装置１では、スライド部１１を構成する操作ツマミ支持部１１ｃや、連結部材１１ｄ、ストッパ支持部１１ｅ、ストッパ１１ｆをそれぞれ別部材で構成しており、それらを結合（連結）して使用するようにしているため、この施錠装置１を高さの異なる雨戸２に使用したり、異なる形状の他の下枠や上枠３２への施解錠等に使用したり、さらには召合せ框２１や召合せ框２１以外の縦框２４への設置高さを変更する場合でも、操作ツマミ支持部１１ｃやストッパ支持部１１ｅはそのまま共通のものを使用し、連結部材１１ｄやストッパ１１ｆの長さ等を変更するだけで済むので、部品点数や在庫点数を減らすことができる。 Moreover, in the locking device 1 of this embodiment, the operation knob support part 11c which comprises the slide part 11, the connection member 11d, the stopper support part 11e, and the stopper 11f are each comprised by the separate member, and these are couple | bonded (connection) Therefore, the locking device 1 can be used for the shutter 2 having a different height, used for locking / unlocking the lower frame or the upper frame 32 of other shapes, Even when the installation height of the sump rod 21 or the vertical rod 24 other than the sump rod 21 is changed, the operation knob support portion 11c and the stopper support portion 11e are used as they are, and the connecting member 11d and the stopper 11f are used. Since it is only necessary to change the length and the like, the number of parts and the number of stocks can be reduced.

なお、上記実施形態の説明では、本発明に係る戸の施錠装置１を、１本の上枠３２と下枠３１との間で移動する複数枚の雨戸２，…のうち、戸袋３３側の雨戸２の召合せ框２１に２つ設けて説明したが、本発明では、このような引き戸式の雨戸２に限らず、引き込み戸、両開き戸などの雨戸にも適用可能であり、また、雨戸以外の戸にも適用可能であり、さらには、召合せ框２１に下枠３１用か上枠３２用のどちらか１つだけ設けても良いし、召合せ框２１以外の縦框２４に１または２つ設けるようにしても勿論良い。 In the description of the above embodiment, the door locking device 1 according to the present invention includes a plurality of shutters 2 that move between the upper frame 32 and the lower frame 31.
