特許文献１に記載された錠装置は、いくらシャッターを施錠していても、侵入者に中間錠用スラット付近のガイドレールを屋外側から無理矢理開かれ中間錠用スラットが手前に引っ張り出されることにより、係止体が係止具から外れて解錠されてしまう虞がある。また、中間錠用スラット前面のガイドレールの隙間からドライバー等を突っ込まれて直接係止体が回動されることにより、解錠されてしまう虞もある。 No matter how much the shutter is locked, the locking device described in Patent Document 1 is forced to open the guide rail near the intermediate locking slat from the outdoor side to the intruder, and the intermediate locking slat is pulled forward. There is a risk that the locking body may come off the locking tool and be unlocked. In addition, there is a possibility that the driver or the like is thrust from the gap between the guide rails on the front surface of the intermediate locking slat and the locking body is directly rotated to be unlocked.

このため、ガイドレールを補強して開かれ難くしたり、ガイドレールの隙間から直接係止体が操作されないように、ガイドレール内の係止具や係止体の周囲に、それらを覆う部材を取り付けたりして解錠され難くしている。しかし、中間錠用スラットより下方のスラットがガイドレールから引き出された後、窓ガラスを破壊されて侵入されてしまう虞がある。これを防ぐため、ボトムスラットに単に同じような錠装置を取り付けることも考えられるが、ガイドレールは上下中間位置に比べて下端では開かれ易く、やはりガイドレールの補強や、係止体又は係止具を覆う部材といったものを別途取り付けなければ効果が薄く、コストが低く抑えられない問題があった。 For this reason, reinforcing the guide rail to make it difficult to open, or to prevent the locking body from being operated directly from the gap between the guide rails, around the locking tool and locking body in the guide rail, It is difficult to unlock by attaching. However, after the slats below the intermediate lock slats are pulled out of the guide rail, the window glass may be broken and intruded. In order to prevent this, it is possible to simply attach a similar locking device to the bottom slat, but the guide rail is easier to open at the lower end than the upper and lower middle positions. If a member such as a member covering the tool is not attached separately, the effect is thin and there is a problem that the cost cannot be kept low.

The upper lock 91 includes a lock body 911 that is screwed to the joining piece 56 of the guide rail 5 and attached to the vertical frame 6, a lock lever 912 that is rotatably attached to the lock body 911, and the lock body 911. And a torsion spring 914 incorporated between the slide member 913 and the lock body 911.

上錠91を構成する錠本体911について説明する。錠本体911は、屋内側プレート911eと屋外側プレート911fとにより、錠レバー912とスライド部材913とを挟み込んだ構成である（図７参照）。屋外側プレート911fの内側縁（シャッターパネル２側、図１及び図３参照）には、ガイドレール５の接合片56にネジ止めするためのネジ孔が形成された雌ネジ部911aが上下２ヶ所に設けられている。また、屋内側プレート911eの内側縁には、前記各雌ネジ部911aに被せてネジ及び雌ネジ部911aに挟持される結合部911gが上下２ヶ所に設けられている。これにより、錠本体911は、屋内側プレート911eの結合部911gと屋外側プレート911fの雌ネジ部911aとをネジ止めにより一体化すると同時に、ガイドレール５の接合片56に固定される。錠本体911は、前記結合部911g及び雌ネジ部911aを除いて上下左右に開放し、錠レバー912を回動させたり、スライド部材913を通すことができるようにしている。 The lock body 911 constituting the upper lock 91 will be described. The lock body 911 has a configuration in which a lock lever 912 and a slide member 913 are sandwiched between an indoor side plate 911e and an outdoor side plate 911f (see FIG. 7). On the inner edge of the outdoor side plate 911f (on the shutter panel 2 side, see FIG. 1 and FIG. 3), there are two upper and lower female screw portions 911a in which screw holes for screwing to the joining pieces 56 of the guide rail 5 are formed. Is provided. In addition, on the inner edge of the indoor side plate 911e, two coupling portions 911g are provided at the upper and lower portions so as to cover the female screw portions 911a and be held between the screws and the female screw portions 911a. Accordingly, the lock body 911 is fixed to the joining piece 56 of the guide rail 5 at the same time as the coupling portion 911g of the indoor side plate 911e and the female screw portion 911a of the outdoor side plate 911f are integrated by screwing. The lock body 911 is opened vertically and horizontally except for the coupling portion 911g and the female screw portion 911a so that the lock lever 912 can be rotated and the slide member 913 can be passed.

屋外側プレート911fの外側縁には、錠レバー912に設けた解錠位置規制部912b又は施錠位置規制部912cを当接させて、錠レバー912の解錠姿勢又は施錠姿勢を規制する回動規制部911bを、屋外側から屋内側へ向けて曲げ起こして形成している。本例は、解錠位置規制部912b、施錠位置規制部912c及び回動規制部911bにより、錠レバー912の回動を規制する規制機構を構成する。錠レバー912は、屋外側プレート911fから貫通して屋内側プレート911eに先端を支持される回動ピン911cに回動自在に取り付けられ、またスライド部材913は同じく屋外側プレート911fから貫通して屋内側プレート911eに先端を支持される取付ピン911dを上下方向の長孔であるガイド溝913aに貫通させている。回動ピン911c及び取付ピン911dは、屋内側プレート911eに支持される先端をそれぞれかしめることで抜け止めを図ると共に、屋内側プレート911e及び屋外側プレート911fを錠レバー912の厚みの間隔を保って一体化する役割も有している。 The outer edge of the outdoor side plate 911f is brought into contact with the unlocking position restricting portion 912b or the locking position restricting portion 912c provided on the lock lever 912 so that the unlocking posture or the locking posture of the lock lever 912 is restricted. The part 911b is bent and raised from the outdoor side toward the indoor side. In this example, the unlocking position restricting portion 912b, the locking position restricting portion 912c, and the rotation restricting portion 911b constitute a restricting mechanism that restricts the rotation of the lock lever 912. The lock lever 912 penetrates from the outdoor side plate 911f and is rotatably attached to a pivot pin 911c supported at the tip of the indoor side plate 911e, and the slide member 913 penetrates from the outdoor side plate 911f in the same manner. A mounting pin 911d whose tip is supported by the inner plate 911e is passed through a guide groove 913a which is a long hole in the vertical direction. The pivot pin 911c and the mounting pin 911d are prevented from coming off by caulking the tips supported by the indoor side plate 911e, and the indoor side plate 911e and the outdoor side plate 911f are kept at the interval of the thickness of the lock lever 912. Have a role to integrate.

上錠91を構成する錠レバー912について説明する。錠レバー912は、回動ピン911cに回動自在に取り付けられている。この錠レバー912は、先端に鉤状をしたフック912aを備えている。本例では、前記フック912aを先端に備えた錠レバー912が上係合体となる。ここで、錠レバー912が直立姿勢となって前記フック912aが錠本体911内に収容された状態が解錠姿勢であり（図10参照）、錠レバー912が傾倒して水平姿勢となってフック912aが錠本体911から突出し、垂下した状態が施錠姿勢である（図12参照）。このように、錠レバー912の回動範囲は、約90度あればよい。錠レバー912を前記回動範囲で回動規制するため、本例の錠レバー912は、回動軸を挟んだフック912aと反対側の円弧周縁に、錠レバー912の解錠姿勢で錠本体911の回動規制部911bに上方から当接する解錠位置規制部912bと、同様に錠レバー912の施錠姿勢で前記回動規制部911bに下方から当接する施錠位置規制部912cとを設けている。これら解錠位置規制部912b及び施錠位置規制部912cと回動規制部911bとの組み合わせにより、錠レバー912の回動を規制する規制機構を構成する。 The lock lever 912 constituting the upper lock 91 will be described. The lock lever 912 is rotatably attached to the rotation pin 911c. The lock lever 912 includes a hook 912a having a hook shape at the tip. In this example, the lock lever 912 provided with the hook 912a at the tip is the upper engagement body. Here, the unlocked position is when the lock lever 912 is in the upright position and the hook 912a is housed in the lock body 911 (see FIG. 10), and the lock lever 912 is tilted and is in the horizontal position. The state where 912a protrudes from the lock body 911 and hangs down is the locking posture (see FIG. 12). Thus, the rotation range of the lock lever 912 may be about 90 degrees. In order to restrict the rotation of the lock lever 912 within the rotation range, the lock lever 912 of the present example has a lock body 911 in the unlocked posture of the lock lever 912 around the arc periphery opposite to the hook 912a with the rotation shaft interposed therebetween. An unlocking position restricting portion 912b that comes into contact with the rotation restricting portion 911b from above, and a locking position restricting portion 912c that comes into contact with the turn restricting portion 911b from below in the same manner as the locking lever 912 is provided. A combination of the unlocking position restricting portion 912b and the locking position restricting portion 912c and the turning restricting portion 911b constitutes a restricting mechanism that restricts the rotation of the lock lever 912.

錠レバー912の回動を操作部93のロッド931の昇降に連動させるため、錠レバー912には回動半径方向に延びる係合溝912fを形成し、前記ロッド931の下端に接続するスライド部材913に設けた押圧突起913cを前記係合溝912fの上方又は下方に位置する内周縁912d,912dのいずれかに当接させている。係合溝912fは、錠レバー912が施錠姿勢（水平姿勢、図12参照）にあるとき、錠本体911の内側面に向けて下り勾配45度の切れ込みであり、ロッド931を引き上げるとスライド部材913が上昇し、前記スライド部材913の押圧突起913cが上方に位置する内周縁912dを押して錠レバー912を起立させ、解除姿勢に移行させる。逆に、錠レバー912が解錠姿勢（直立姿勢、図10参照）にあるとき、ロッド931を押し下げるとスライド部材913が下降し、前記スライド部材913の押圧突起913cが下方に位置する内周縁912dを押して錠レバー912を傾倒させ、施錠姿勢に移行させる。スライド部材913の押圧突起913cは、常時係合溝912f内に位置するが、あくまでロッド931に従う昇降運動しかしないことを利用し、下方に位置する内周縁912dに前記押圧突起913cに水平方向から当接する戻り止め縁912eを設け、施錠姿勢にある錠レバー912が外力によって起き上がらないようにしている（図12参照）。 In order to interlock the rotation of the lock lever 912 with the raising and lowering of the rod 931 of the operation portion 93, the lock lever 912 is formed with an engagement groove 912f extending in the rotation radial direction, and is connected to the lower end of the rod 931. The pressing protrusion 913c provided on the inner surface is brought into contact with one of the inner peripheral edges 912d and 912d located above or below the engaging groove 912f. When the lock lever 912 is in the locking posture (horizontal posture, see FIG. 12), the engagement groove 912f is a cut of 45 degrees downward toward the inner surface of the lock body 911. Then, the pressing projection 913c of the slide member 913 pushes the inner peripheral edge 912d positioned above to raise the lock lever 912 and shift to the release posture. Conversely, when the lock lever 912 is in the unlocked posture (upright posture, see FIG. 10), when the rod 931 is depressed, the slide member 913 is lowered, and the inner peripheral edge 912d where the pressing protrusion 913c of the slide member 913 is positioned below. Is pushed to tilt the lock lever 912 to shift to the locked position. The pressing protrusion 913c of the slide member 913 is always located in the engagement groove 912f, but by utilizing the fact that it only moves up and down according to the rod 931, the pressing protrusion 913c is pressed against the pressing protrusion 913c from the horizontal direction. A detent edge 912e that comes into contact is provided to prevent the lock lever 912 in the locked posture from being raised by an external force (see FIG. 12).

上錠91を構成するスライド部材913について説明する。スライド部材913は、ロッド931と接続される上部を錠本体911から常に上方へ突出させた状態で錠本体911内を昇降自在に取り付けられる。スライド部材913は、上下方向の長穴からなるガイド溝913aに、錠本体911に固定した取付ピン911dを貫通させ、前記取付ピン911dにより昇降範囲が規制され、また昇降方向が案内されている。このスライド部材913は、回動ピン911cとの干渉を避けるため、下部を二股に分けている。前記二股の一方、錠本体911の内側面寄りの下端には、錠レバー912に設けた係合溝912fの内周縁912d,912dに当接する押圧突起913cを形成している。この押圧突起913cの先端は、屋内側プレート911eに開口させた上下方向に延びるガイド孔911h内に挿入され、昇降が案内される。また、前記二股の他方、錠本体911の内側面から遠い側は、ガイド溝913aと協働してスライド部材913の傾倒を防止するガイド片913dとして形成されている。ガイド片913dは、錠本体911に設けた回動規制部911bと回動ピン911cに嵌めた環状スペーサ915とに左右方向から挟まれた範囲で上下動する。このスライド部材913は、錠本体911から突き出した上端をロッド931にネジ止め固定することで操作部93に連結され、操作部93による錠レバー912の回動操作を可能にしている。 The slide member 913 constituting the upper lock 91 will be described. The slide member 913 is attached so as to be movable up and down in the lock body 911 in a state where the upper part connected to the rod 931 always protrudes upward from the lock body 911. In the slide member 913, a mounting groove 911d fixed to the lock body 911 is passed through a guide groove 913a formed of an elongated hole in the vertical direction, the lifting range is restricted by the mounting pin 911d, and the lifting direction is guided. The slide member 913 has a lower portion divided into two for avoiding interference with the rotation pin 911c. A pressing protrusion 913c that abuts against the inner peripheral edges 912d and 912d of the engaging groove 912f provided in the lock lever 912 is formed at the lower end of one of the two forks close to the inner surface of the lock body 911. The tip of the pressing projection 913c is inserted into a guide hole 911h that opens in the indoor side plate 911e and extends in the vertical direction, and is guided to ascend and descend. The other side of the fork and the side far from the inner surface of the lock body 911 is formed as a guide piece 913d that cooperates with the guide groove 913a to prevent the slide member 913 from tilting. The guide piece 913d moves up and down within a range sandwiched between a rotation restricting portion 911b provided on the lock body 911 and an annular spacer 915 fitted on the rotation pin 911c from the left and right directions. The slide member 913 is connected to the operation unit 93 by screwing and fixing the upper end protruding from the lock body 911 to the rod 931, and enables the operation of the lock lever 912 by the operation unit 93.

スライド部材913は、ガイド溝913a近傍に付勢部材用突起913bを屋内側に向けて折曲げ形成し、トーションバネ（捻りコイルバネ）914の一端を前記付勢部材用突起913bに保持し、スライド部材913の昇降に合わせて前記トーションバネ914の一端が昇降するようにしている。これに対し、トーションバネ914の他端は、錠本体911に位置固定された取付ピン911dに保持されていている。これにより、トーションバネ914は、スライド部材913の昇降によって姿勢を変化させ、スライド部材913の上昇端付近ではスライド部材913を押し上げる方向に付勢し、逆にスライド部材913の下降端付近ではスライド部材913を押し下げる方向に付勢することができ、錠レバー912の施錠姿勢及び解除姿勢の保持を助けるほか、ロッド931を介した施錠又は解錠操作に適度な節動感を与えている。 The slide member 913 is formed by bending a biasing member projection 913b in the vicinity of the guide groove 913a toward the indoor side, holding one end of a torsion spring (torsion coil spring) 914 on the biasing member projection 913b, One end of the torsion spring 914 is raised and lowered as the 913 is raised and lowered. On the other hand, the other end of the torsion spring 914 is held by a mounting pin 911d fixed to the lock body 911. As a result, the torsion spring 914 changes its posture by raising and lowering the slide member 913, and urges the slide member 913 in the direction of pushing up the slide member 913 near the rising end, and conversely, near the lower end of the slide member 913. The 913 can be urged in the downward direction to help maintain the locking and unlocking postures of the locking lever 912, and gives a moderate feeling of movement to the locking or unlocking operation via the rod 931.

防犯錠装置９の操作部93について説明する。操作部93は、縦枠６の内側面に埋没させて前記縦枠６の外側に表れる上下方向に長尺なカバー933と、縦枠６の内部に配設される前記カバー933に対応する長尺な台座932とにより、ガイドレール５の接合片56を挟持させて、設置される。カバー933は、上下方向に長い凹部933aが外側面に向けて凹設されており、凹部933aの底面中央に、上下に細長い長孔933dを設けている。台座932には、前記カバー933の長孔933dに対応する位置関係で、同様に上下に細長い長孔932bを設けている。また、カバー933は凹部933aの上下に台座932に向けて突出した雌ネジ部933b,933bが、台座932は長孔932bの上下に前記カバー933に向けて突出した嵌合突起932a,932aが設けられている。 The operation unit 93 of the security lock device 9 will be described. The operation unit 93 is buried in the inner surface of the vertical frame 6 and has a cover 933 that is long in the vertical direction and appears outside the vertical frame 6, and a length corresponding to the cover 933 disposed inside the vertical frame 6. The joining piece 56 of the guide rail 5 is sandwiched by the long pedestal 932 and installed. The cover 933 has a concave portion 933a that is long in the vertical direction and is formed toward the outer surface. A long and narrow long hole 933d is provided in the center of the bottom surface of the concave portion 933a. The pedestal 932 is similarly provided with elongated holes 932b that are vertically elongated in a positional relationship corresponding to the elongated holes 933d of the cover 933. Further, the cover 933 is provided with female screw portions 933b and 933b projecting toward the base 932 above and below the recess 933a, and the base 932 is provided with fitting projections 932a and 932a projecting toward the cover 933 above and below the long hole 932b. It has been.

操作部93を取り付けるガイドレール５の接合片56は、カバー933の凹部933aが嵌入できる大きさの角孔562と、前記角孔562の上下にカバー933の雌ネジ部933bを差し込む大きさの孔561,561を設けている。前記接合片56に対応する縦枠６の内側片63には、台座932及びカバー933との干渉を排除する切欠631が設けられている。操作部93は、図８及び図９に見られるように、ガイドレール５の接合片56に穿設された孔561,561にカバー933の雌ネジ部933bを差し込んで前記カバー933を位置決めし、接合片56から突出する雌ネジ部933bに台座932の対応する嵌合突起932aを外嵌し、台座932及びカバー933で操作ツマミ934を挟んだ状態で、台座932側から嵌合突起932aを通じてカバー933の雌ネジ部933bにネジを螺着して、カバー933及び台座932を一体化すると共に、ガイドレール５に取り付ける。本例は、スライド部材913、ロッド931及び操作ツマミ934により、錠レバー912を回動させる操作機構を構成する。 The joining piece 56 of the guide rail 5 to which the operation portion 93 is attached has a square hole 562 large enough to fit the concave portion 933a of the cover 933, and a hole large enough to insert the female screw portion 933b of the cover 933 above and below the square hole 562. 561,561 are provided. The inner piece 63 of the vertical frame 6 corresponding to the joining piece 56 is provided with a notch 631 for eliminating interference with the base 932 and the cover 933. As shown in FIGS. 8 and 9, the operation portion 93 positions the cover 933 by inserting the female screw portion 933 b of the cover 933 into the holes 561 and 561 formed in the joint piece 56 of the guide rail 5. 56, the corresponding fitting protrusion 932a of the pedestal 932 is externally fitted to the female threaded portion 933b, and the operation knob 934 is sandwiched between the pedestal 932 and the cover 933. A screw is screwed into the female screw portion 933b so that the cover 933 and the base 932 are integrated and attached to the guide rail 5. In this example, the slide member 913, the rod 931, and the operation knob 934 constitute an operation mechanism that rotates the lock lever 912.

操作部93を構成する操作ツマミ934は、カバー933に向けてノブ934aを突設し、また台座932に向けて凸片934bを突設した構造で、台座932とカバー933とに挟まれた状態で、前記ノブ934aをカバー933の長孔933dから突出させ、また凸片934bを台座932の長孔932bに差し込み、ノブ934aがカバーの長孔933dの範囲で昇降自在になっている。上錠91のスライド部材913から延びるロッド931は、台座932から突出する操作ツマミ934の凸片934bに対してネジ止めにより連結される。ロッド931は、上下端部に雌ネジ孔931aが上下２箇所ずつ形成された平板からなり、下端部はスライド部材913に、上端部は操作ツマミ934にそれぞれネジ止めにより連結する。本例の防犯錠装置９は、操作部93を上錠91から離した高い位置に取り付けているため、ロッド931が相当な長さとなり、比較的重量物になる。しかし、トーションバネ914の付勢により前記ロッド931を支持しているため、ロッド931が自然に下降して、解錠姿勢にある錠レバー912が勝手に傾倒しないようになっている。 The operation knob 934 constituting the operation unit 93 has a structure in which a knob 934a protrudes toward the cover 933 and a protruding piece 934b protrudes toward the base 932, and is sandwiched between the base 932 and the cover 933. Thus, the knob 934a is protruded from the long hole 933d of the cover 933, and the convex piece 934b is inserted into the long hole 932b of the base 932, so that the knob 934a can be raised and lowered within the range of the long hole 933d of the cover. The rod 931 extending from the slide member 913 of the upper lock 91 is connected to the convex piece 934b of the operation knob 934 protruding from the base 932 by screwing. The rod 931 is formed of a flat plate having two upper and lower female screw holes 931a at the upper and lower ends, and the lower end is connected to the slide member 913 and the upper end is connected to the operation knob 934 by screws. In the security lock device 9 of this example, since the operation portion 93 is attached at a high position away from the upper lock 91, the rod 931 has a considerable length and is relatively heavy. However, since the rod 931 is supported by the urging force of the torsion spring 914, the rod 931 naturally descends so that the lock lever 912 in the unlocked posture does not tilt without permission.

防犯錠装置９の錠受け92について説明する。錠受け92は、図14に見られるように、係合部921、取付部922及び取付補強部923から構成される。係合部921は、厚板鋼板を折曲げ形成した平面視方形の筒状体である（図３及び図7参照）。上錠91の錠レバー912がフック912aを上方から差し込んで係止することにより、上下、前後及び左右方向に位置規制される錠受け92の主要部である。取付部922は、前記係合部921をボトムスラット23の底片231に対して位置固定する部位である。この取付部922は、ボトムスラット23の背面側に向けた水平な折り曲げ片からなり、前記折り曲げ片をボトムスラット23の底片231に接面させ、前記底片231の下方からネジ止めして位置固定される。取付補強部923は、前記係合部921及び取付部922のボトムスラット23に対する一体性を高め、大きな外力によって取付部922がボトムスラット23から背面側に引き剥がされてしまうことを強力に防止する部位である。これから、本例の取付補強部923は、ボトムスラット23の背面へ上下に対向させて設けた装着溝232,232内に上下縁が差し込まれる面板状にしている。 The lock holder 92 of the security lock device 9 will be described. As shown in FIG. 14, the lock receiver 92 includes an engagement portion 921, an attachment portion 922, and an attachment reinforcement portion 923. The engaging portion 921 is a cylindrical body having a rectangular shape in plan view formed by bending a thick steel plate (see FIGS. 3 and 7). The lock lever 912 of the upper lock 91 is the main part of the lock receiver 92 whose position is regulated in the vertical, front-rear and left-right directions by inserting and locking the hook 912a from above. The attachment portion 922 is a portion that fixes the position of the engaging portion 921 with respect to the bottom piece 231 of the bottom slat 23. The mounting portion 922 is formed of a horizontal bent piece facing the back side of the bottom slat 23, the bent piece is brought into contact with the bottom piece 231 of the bottom slat 23, and the position is fixed by screwing from below the bottom piece 231. The The attachment reinforcing portion 923 enhances the integrity of the engagement portion 921 and the attachment portion 922 with respect to the bottom slat 23, and strongly prevents the attachment portion 922 from being peeled away from the bottom slat 23 by the large external force. It is a part. Accordingly, the attachment reinforcing portion 923 of the present example has a face plate shape in which the upper and lower edges are inserted into the mounting grooves 232 and 232 provided vertically opposite to the back surface of the bottom slat 23.

防犯錠装置９の下錠94について説明する。図14に見られるように、本例では、防犯錠装置９によるシャッターパネル２（図14中スラット21及びボトムスラット23で代表）の位置規制をより強化するため、筒状体からなる係合部921に下方から嵌合し、錠受け92を前後及び左右方向に位置規制する下錠94を、水切り７から突設している。本例の下錠94は、図13に示すように、水切り７に設けた上下貫通孔に下方から突出させて位置固定したボルト941を下係合体として構成される。前記ボルト941は、例えば水切り７背部の空間内に差し込まれたナット942等に螺合させて位置固定する。 The lower lock 94 of the security lock device 9 will be described. As shown in FIG. 14, in this example, in order to further strengthen the position regulation of the shutter panel 2 (represented by the slats 21 and the bottom slats 23 in FIG. 14) by the security lock device 9, the engaging portion made of a cylindrical body is used. A lower lock 94 that fits from below to 921 and restricts the position of the lock receiver 92 in the front-rear and left-right directions protrudes from the drainer 7. As shown in FIG. 13, the lower lock 94 in this example includes a bolt 941 that protrudes from below and is fixed to a vertical through hole provided in the drainer 7 as a lower engagement body. For example, the bolt 941 is screwed into a nut 942 or the like inserted into the space behind the drainer 7 to fix the position.

次に、本例の防犯錠装置９による施錠の仕組みについて説明する。まず、シャッターパネル２を引き降ろすと、シャッター１は中間錠装置８によって自動的に施錠状態となる。ここで、シャッターパネル２の昇降に際する負荷を軽減させるバネ41（図１参照）がドラム４に組み込まれているため、シャッターパネル２を最下端の閉鎖位置まで降ろした際、前記バネ41により反動が生じて、シャッターパネル２が幾分持ち上がってしまう場合がある。本例における中間錠装置８は、自動的にシャッター1を施錠状態にすることで前記シャッターパネル２の持ち上がりを防止し、ボトムスラット23を水切り７に確実に接面させることにより、防犯錠装置９により確実に施錠できるようにする働きも有する。これから、本発明の防犯錠装置９は、シャッターパネル2を拘束する別の錠装置と併用することが好ましい。 Next, the mechanism of locking by the security lock device 9 of this example will be described. First, when the shutter panel 2 is pulled down, the shutter 1 is automatically locked by the intermediate lock device 8. Here, since the spring 41 (see FIG. 1) for reducing the load when the shutter panel 2 is moved up and down is incorporated in the drum 4, the spring 41 is moved by the spring 41 when the shutter panel 2 is lowered to the lowermost closed position. A reaction may occur and the shutter panel 2 may be lifted somewhat. The intermediate lock device 8 in this example prevents the lifting of the shutter panel 2 by automatically bringing the shutter 1 into the locked state, and makes the bottom slat 23 contact the drainer 7 securely, thereby preventing the security lock device 9. It also has a function to ensure locking. From this, it is preferable to use the security lock device 9 of the present invention in combination with another lock device that restrains the shutter panel 2.

ボトムスラット23を水切り７に接面させた状態（図９及び図10の状態）から操作部93の操作ツマミ934を降ろすと、ロッド931を介してスライド部材913が下降し、スライド部材913の押圧突起913cが錠レバー912の下方に位置する内周縁912dを押圧して、前記錠レバー912を内向きに下方回動させる（図11参照）。錠レバー912が回動すると、トーションバネ914が捻られて両端を離隔させる反発力を発生させる。このトーションバネ914の反発力に抗して、スライド部材913を更に下降させると、トーションバネ914は取付ピン911dを中心に姿勢を変化させ、今度は捻りを解消しながら両端を開いていく。そして、錠レバー912は、施錠位置規制部912cが回動規制部911bの下面に当接する水平な施錠姿勢で停止し、防犯錠装置９が施錠状態となる（図12参照）。このとき、錠レバー912の戻り止め縁912eがスライド部材913の押圧突起913cに当接することにより、錠レバー912の起き上がりが規制されるので、シャッターパネル２に大きな衝撃が加わって、錠レバー912を解錠方向へ回動させようとしても、防犯錠装置９が解錠される虞はない。 When the operation knob 934 of the operation unit 93 is lowered from the state where the bottom slat 23 is in contact with the drainer 7 (the state shown in FIGS. 9 and 10), the slide member 913 is lowered via the rod 931 and the slide member 913 is pressed. The protrusion 913c presses the inner peripheral edge 912d positioned below the lock lever 912, thereby rotating the lock lever 912 downward inward (see FIG. 11). When the lock lever 912 rotates, the torsion spring 914 is twisted to generate a repulsive force that separates both ends. When the slide member 913 is further lowered against the repulsive force of the torsion spring 914, the torsion spring 914 changes its posture around the mounting pin 911d, and this time opens both ends while eliminating the twist. Then, the lock lever 912 stops in a horizontal locking posture in which the locking position restricting portion 912c contacts the lower surface of the rotation restricting portion 911b, and the security lock device 9 enters the locked state (see FIG. 12). At this time, since the detent edge 912e of the lock lever 912 abuts against the pressing protrusion 913c of the slide member 913, the rising of the lock lever 912 is restricted, so that a large impact is applied to the shutter panel 2 and the lock lever 912 is moved. There is no possibility that the security lock device 9 is unlocked even if it is rotated in the unlocking direction.

次に、本例の防犯錠装置９による解錠の仕組みについて説明する。施錠状態（図12の状態）から操作部93の操作ツマミ934を引き上げると、ロッド931を介してスライド部材913が上昇し、スライド部材913の押圧突起913cが錠レバー912の上方に位置する内周縁912dを押圧して、錠レバー912を外向きに上方回動させる（図11参照）。こうして錠レバー912が回動すると、施錠する際と同様に、トーションバネ914のコイル部分が捻られた反発力を発生させるが、前記反発力に抗して操作ツマミ934を上げていくとやがてトーションバネ914は姿勢を変化させて捻りを緩め始める。そして、錠レバー912は、解錠位置規制部912bが回動規制部911bの上面に当接する直立な解錠姿勢で停止し、防犯錠装置９が解錠状態となる（図10参照）。このとき、錠レバー912は、トーションバネ914がスライド部材913を押し上げているので、前記スライド部材913との係合関係により解錠姿勢が保たれている。防犯錠装置９を解錠した後、中間錠装置８を解錠すれば、シャッターパネル２の巻き上げが可能となる。 Next, the mechanism of unlocking by the security lock device 9 of this example will be described. When the operation knob 934 of the operation portion 93 is pulled up from the locked state (the state shown in FIG. 12), the slide member 913 rises via the rod 931, and the inner peripheral edge where the pressing protrusion 913c of the slide member 913 is located above the lock lever 912. By pressing 912d, the lock lever 912 is rotated upward outward (see FIG. 11). When the lock lever 912 is rotated in this manner, the coil portion of the torsion spring 914 generates a repulsive force that is twisted in the same manner as when locking, but when the operation knob 934 is raised against the repulsive force, the torsion is eventually produced. The spring 914 changes its posture and begins to loosen the twist. Then, the lock lever 912 stops in an upright unlocking posture in which the unlocking position restricting portion 912b contacts the upper surface of the rotation restricting portion 911b, and the security lock device 9 enters the unlocked state (see FIG. 10). At this time, since the torsion spring 914 pushes up the slide member 913, the unlocking posture of the lock lever 912 is maintained by the engagement relationship with the slide member 913. If the intermediate lock device 8 is unlocked after the security lock device 9 is unlocked, the shutter panel 2 can be rolled up.

最後に本発明の防犯錠装置９を電動シャッターに適用する場合について説明する。上記例示は、手動式のシャッターパネル２についてであったが、本発明の防犯錠装置９は、ドラム４を正逆駆動させるモータ（開閉機）を備えた電動式のシャッターパネル２にも容易に適用できる。電動式のシャッターパネル２に対しても、シャッターパネル２の重量を軽減させるバネ41がドラム４に組み込まれているが、モータの減速機の抵抗やモータの制御によりシャッターパネル２の持ち上がりは抑制されているので、中間錠装置８（図１参照）又はその他の錠装置は不要である。この場合、防犯錠装置９は上記例示と全く同じ構成を用いることができ、しかも左右一方又は両方の縦枠６に取り付けるだけなので、防犯錠装置９以外の錠装置等を不要とする電動シャッターは、低コストで提供できる利点がある。また、モータにブレーキ機構を組み込んだり、シャッターパネル２の持ち上げを感知する上昇センサを設け、前記上昇センサの感知によりモータを閉鎖駆動させる制御機構を組み込めば、前記各機構と本発明の防犯錠装置９との組み合わせにより、より優れた防犯性を発揮させることができる。 Finally, the case where the security lock device 9 of the present invention is applied to an electric shutter will be described. The above example was for the manual shutter panel 2, but the security lock device 9 of the present invention can be easily applied to the electric shutter panel 2 provided with a motor (opening / closing device) for driving the drum 4 forward and reverse. Applicable. Although the spring 41 for reducing the weight of the shutter panel 2 is incorporated in the drum 4 with respect to the electric shutter panel 2, the lifting of the shutter panel 2 is suppressed by the resistance of the motor speed reducer and the motor control. Therefore, the intermediate locking device 8 (see FIG. 1) or other locking device is unnecessary. In this case, the security lock device 9 can use the same configuration as the above-described example, and is only attached to one of the left and right vertical frames 6. Therefore, an electric shutter that does not require a lock device other than the security lock device 9 is used. There is an advantage that can be provided at low cost. Further, if a brake mechanism is incorporated in the motor or a lift sensor for sensing the lifting of the shutter panel 2 is provided, and a control mechanism for driving the motor to be closed by the sensing of the lift sensor is incorporated, the mechanisms and the security lock device of the present invention are provided. By combining with 9, better crime prevention can be exhibited.
