While one side surface of the movable convex portions 35 and 35 abuts on one side surface of the fixed convex portions 45, 45, 55 and 55 of the inner plate 50, the rotation of the lock lever is stopped. When the movable convex portions 35, 35 and the fixed convex portions 45, 45, 55, 55 are pushed in the locking direction from the temporary stop position with a rotational torque of a predetermined magnitude or more against the elastic force, the movable convex portions The portions 35 and 35 and the fixed convex portions 45, 45, 55, and 55 are elastically deformed so that the movable convex portions 35 and 35 do not slide on the side surfaces of the fixed convex portions 45, 45, 55, and 55. It is characterized in that the outer ring 40 is integrally rotated by getting over.

請求項４に記載の発明は、請求項３に記載の打掛錠Ｒにおいて、たとえば以下に示す図示実施の形態のとおり、前記回転制御手段３０の前記可動凸部３５・３５を、前記アウターリング４０の外輪部２６の軸芯を中心とした点対称の位置の双方に突設すると共に、一対の前記固定凸部４５・４５，５５・５５も、前記インナープレート５０の外周縁５０ｂの軸芯を中心とした点対称の位置の双方に突設し、前記ロックレバー１０を、起立した解錠位置から施錠方向又は解錠方向に回転すると、それぞれ起立した解錠位置に対して所定角度β回転した４つの一時停止位置ｐ・ｑ・ｒ・ｓで、前記アウターリング４０の可動凸部３５・３５が前記インナープレート５０の固定凸部４５・４５，５５・５５の側面に当接して前記ロックレバー１０の回転を停止する一方、解錠時、該ロックレバー１０を、前記可動凸部３５・３５と固定凸部４５・５５の弾性力に抗して所定の大きさ以上の回転トルクで前記起立した解錠位置から解錠方向に前記一時停止位置を越えて回転することがあると、前記ロックレバー１０を一部に係止してそれ以上の回転を規制してなることを特徴とする。 According to a fourth aspect of the present invention, in the hooking lock R according to the third aspect, the movable convex portions 35 and 35 of the rotation control means 30 are moved to the outer ring, for example, as shown in the embodiment shown below. A pair of fixed protrusions 45, 45, 55, and 55 are provided at both the point-symmetrical positions around the axis of the outer ring portion 26 of the 40 and the axis of the outer peripheral edge 50 b of the inner plate 50. When the lock lever 10 is rotated in the locking direction or the unlocking direction from the standing unlocking position, it rotates by a predetermined angle β with respect to the standing unlocking position. At the four temporary stop positions p, q, r, s, the movable convex portions 35, 35 of the outer ring 40 abut against the side surfaces of the fixed convex portions 45, 45, 55, 55 of the inner plate 50, and the lock Lever 10 While the rolling is stopped, at the time of unlocking, the lock lever 10 is lifted with the rotating torque of a predetermined magnitude or more against the elastic force of the movable convex portions 35 and 35 and the fixed convex portions 45 and 55. When rotating beyond the temporary stop position in the unlocking direction from the lock position, the lock lever 10 is locked to a part to restrict further rotation.

請求項１に記載の発明によれば、施錠時にロックレバーの錠杆が係止する高さ位置において、レバー受けを、ロックレバーと一緒に同じ回動式扉又は扉枠の戸先側端部に取り付けるから、いちいち回動式扉又は扉枠側のロックレバーの高さ位置に合わせて、レバー受けを高さ調整しながら取り付ける必要がないために、それだけ設置作業に費やす手間と時間が少なく、簡単に組み付けることができる。 According to the first aspect of the present invention, at the height position where the lock lever of the lock lever is locked at the time of locking, the lever receiver is attached together with the lock lever to the same end of the door or the door frame side of the door. Since it is not necessary to install the lever holder while adjusting the height according to the height position of the pivoting door or the lock lever on the door frame side, the labor and time spent on the installation work is much less. Easy to assemble.

請求項２に記載の発明によれば、レバー受けは、取付板部をレバーベースに重ね合わせて見えないように回動式扉又は扉枠に固定してレバー係止部だけを外部に露出させ、突起等の出っ張りの少ない構造形状をなし、美的外観を良好にすることができる。 According to the second aspect of the present invention, the lever receiver is fixed to the rotary door or door frame so that the mounting plate is not visible on the lever base so that only the lever locking portion is exposed to the outside. In addition, a structural shape with few protrusions and the like can be formed, and an aesthetic appearance can be improved.

請求項３に記載の発明によれば、アウターリングの可動凸部の一側側面がインナープレートの固定凸部の一側側面に当接し、ロックレバーを、錠杆が鉛直に起立した解錠位置から施錠方向へ所定角度傾斜した一時停止位置に保持しているときは、少なくとも回動式扉は解錠状態にあるから、扉枠に強く衝突するように閉めることができる。しかし、ロックレバーを一時停止位置に保持しているときには、可動凸部と固定凸部の弾性力に抗して所定の大きさ以上の回転トルクでロックレバーを施錠方向に押し回し、互いに弾性変位しながら可動凸部が固定凸部を乗り越えない限り、ロックレバーを施錠位置に回転させることができない。従って、ロックレバーを一時停止位置に傾けて位置させる一方、回動式扉を扉枠に強く衝突するように閉めたとしても、そのときの衝撃によっては、ロックレバーが施錠位置側へ回転することはない。その結果、トイレが不使用状態にあるにも拘わらず、いたずら等により回動式扉が閉位置でロックされ、トイレ等を使用できなくなるのを未然に防止することができる。 According to the third aspect of the present invention, the unlocking position in which the one side surface of the movable convex portion of the outer ring is in contact with the one side surface of the fixed convex portion of the inner plate, and the lock lever is erected vertically. When the door is held at a temporary stop position inclined at a predetermined angle in the locking direction, at least the rotary door is in the unlocked state, and can be closed so as to strongly collide with the door frame. However, when the lock lever is held at the temporary stop position, the lock lever is pushed in the locking direction with a rotational torque of a predetermined magnitude or more against the elastic force of the movable convex part and the fixed convex part, and elastically displaced from each other. However, the lock lever cannot be rotated to the locked position unless the movable convex portion gets over the fixed convex portion. Therefore, even if the lock lever is tilted to the temporary stop position and the rotary door is closed so as to strongly collide with the door frame, the lock lever rotates to the lock position side depending on the impact at that time. There is no. As a result, even though the toilet is not in use, it is possible to prevent the pivotable door from being locked in the closed position due to mischief or the like, so that the toilet can no longer be used.

加えて、請求項４に記載の発明では、左右勝手仕様双方の回動式扉又は扉枠に組み付けて使用できるように、回転制御手段は、可動凸部を、アウターリングの外輪部の軸芯を中心とした点対称の位置の双方に突設すると共に、一対の固定凸部も、インナープレートの外周縁の軸芯を中心とした点対称の位置の双方に突設するから、ロックレバーを、起立した解錠位置から施錠方向又は解錠方向に回転すると、それぞれ起立した解錠位置に対して所定角度回転した４つの一時停止位置で、アウターリングの可動凸部がインナープレートの固定凸部の側面に当接してロックレバーの回転を停止させる構造になっている。そこで、解錠時に、起立した解錠位置にあるロックレバーに対し、仮に何らかの外力が加わって可動凸部と固定凸部の弾性力に抗して所定の大きさ以上の回転トルクでロックレバーが解錠方向に強制回転し、先端部が回動式扉又は扉枠の戸先側端部から出っ張る一時停止位置で停止し、回動式扉の開閉動作の障害になることが考えられる。 In addition, in the invention according to claim 4, the rotation control means has the movable convex portion as the axial center of the outer ring portion of the outer ring so that it can be used by being assembled to a right-and-left rotating door or door frame. And a pair of fixed projections project from both point-symmetrical positions around the axis of the outer peripheral edge of the inner plate. When the upright unlocking position is rotated in the locking direction or the unlocking direction, the movable convex part of the outer ring is the fixed convex part of the inner plate at four temporary stop positions rotated by a predetermined angle with respect to the standing unlocking position. The structure is configured to stop the rotation of the lock lever by abutting against the side surface. Therefore, at the time of unlocking, some external force is applied to the lock lever in the standing unlocked position, and the lock lever is rotated with a rotational torque of a predetermined magnitude or more against the elastic force of the movable convex portion and the fixed convex portion. Forcibly rotating in the unlocking direction and stopping at a temporary stop position where the tip end protrudes from the end of the door or the door frame side of the door, which may hinder the opening / closing operation of the door.

しかし、請求項４に記載の発明の打掛錠では、レバー受けを、ロックレバーが施錠位置にあるときにレバー係止部に係止する高さ位置において、ロックレバーと一緒に同じ回動式扉又は扉枠に取り付けるから、解錠時、ロックレバーを、回転制御手段の可動凸部と固定凸部の弾性力に抗して所定の大きさ以上の回転トルクで起立した解錠位置から解錠方向に前記一時停止位置を越えて回転することがあると、ロックレバーを一部に係止してそれ以上の回転を規制し、これにより、ロックレバーの先端部が回動式扉又は扉枠の戸先側端部から出っ張って回動式扉の開閉動作の障害になるのを防止することができる。 However, in the latching lock of the invention according to the fourth aspect, the lever receiver is rotated together with the lock lever at the height position where the lever receiver is locked to the lever locking portion when the lock lever is in the locking position. Since it is attached to the door or door frame, when unlocking, the lock lever is unlocked from the unlocked position raised with a rotational torque of a predetermined size or more against the elastic force of the movable convex part and fixed convex part of the rotation control means. If there is a rotation beyond the temporary stop position in the locking direction, the lock lever is locked to a part and the further rotation is restricted. It can prevent that it protrudes from the door edge side edge part of a frame, and becomes the obstruction | occlusion of the opening / closing operation | movement of a rotary door.

更に、レバー受けＢには、取付板部６０の円板部分６０ａにおいて、嵌合穴４２を間に挟んだ両側にそれぞれ２つずつスタッド挿通穴ａ１・ｂ１、ａ２・ｂ２を、ａ１とａ２、ｂ１とｂ２間にそれぞれゴムキャップ６８の直径に対応する間隔をあけて並設している。しかも、スタッド挿通穴ａ１・ｂ２およびスタッド挿通穴ａ２・ｂ１は、それぞれ嵌合穴４２の軸心を中心とした点対称の位置にあって、スタッド２３・２３間に対応する間隔をあけて設け、左右勝手いずれの仕様の開き扉にも対応してレバー受けＢが取り付けられる構造になっている。 Further, in the lever receiver B, two stud insertion holes a1, b1, a2, b2 are provided on both sides of the disc portion 60a of the mounting plate portion 60 with the fitting hole 42 interposed therebetween, a1, a2, Between b1 and b2, the space | interval corresponding to the diameter of the rubber cap 68 is respectively provided in parallel. In addition, the stud insertion holes a1 and b2 and the stud insertion holes a2 and b1 are in point-symmetrical positions about the axis of the fitting hole 42, and are provided with a corresponding gap between the studs 23 and 23. The lever receiver B can be attached to both the left and right open doors.

表示器Ｃは、丸座３１と、表示板３２と、表示カバー３３を備える。丸座３１は、中心に嵌合穴３４の開いた円盤状をなし、嵌合穴３４の軸心を中心とした点対称の位置に、呼込みビス３６が挿通する挿通穴３７を穿設してなる。表示板３２は、円板状で、片面中心に枢軸１９と対応する角穴８０を軸芯に有する軸筒部３２ａを突設し、他面に略５０度開いた扇形の表示シール３２ｂを貼り付け、開き扉Ｄの施錠状態を示す扇形の朱色部分と、解錠状態を示す扇形の青色部分に色分けしている。表示カバー３３は、表示窓３８の開いた外周が円形のキャップからなる。 The display C includes a round seat 31, a display plate 32, and a display cover 33. The circular seat 31 has a disk shape with a fitting hole 34 opened at the center, and an insertion hole 37 through which the insertion screw 36 is inserted is formed at a point-symmetrical position about the axis of the fitting hole 34. Become. The display plate 32 is disc-shaped, and a shaft tube portion 32a having a square hole 80 corresponding to the pivot shaft 19 at the center of one surface protrudes from the center, and a fan-shaped display seal 32b that opens approximately 50 degrees is pasted on the other surface. A fan-shaped vermilion portion indicating the locked state of the door D and a fan-shaped blue portion indicating the unlocked state are color-coded. The display cover 33 is formed of a cap whose outer periphery of the display window 38 is circular.

そこで、図示打掛錠Ｒでは、組み立てた錠本体Ａを、開き扉Ｄに取り付けるが、そのとき、図６に示すように、レバー受けＢを間に挟んで同じ戸先側端部に組み付ける。そのとき、スタッド２３・２３を点対称の位置にあるスタッド挿通穴ａ１・ｂ２に挿通してから、開き扉Ｄの戸先側端部に予め穿設した両端の呼込穴６９・７０に挿入すると同時に、中心の呼込穴７１にジョイント１１の枢軸１９を挿入し、錠本体Ａを、開き扉Ｄの内側板面ｄ１に、レバー受けＢの円板部分６０ａ（取付板部６０）を間に挟んで配置する。一方、反対側の外側板面ｄ２に表示器Ｃの丸座３１を配置し、呼込みビス３６を挿通穴３７に通してスタッド２３・２３の雌ねじ穴２３ａにねじ込み、錠本体Ａと、表示器Ｃの丸座３１を開き扉Ｄに固着する。 Therefore, in the illustrated locking lock R, the assembled lock body A is attached to the opening door D, and at that time, as shown in FIG. At that time, after inserting the studs 23 and 23 into the stud insertion holes a1 and b2 at the point-symmetrical positions, the studs 23 and 23 are inserted into the receiving holes 69 and 70 at both ends which are drilled in advance at the door end side of the opening door D. At the same time, the pivot 19 of the joint 11 is inserted into the central receiving hole 71, the lock body A is inserted into the inner plate surface d1 of the opening door D, and the disc portion 60a (mounting plate portion 60) of the lever receiver B is interposed. Place between. On the other hand, the circular seat 31 of the display C is disposed on the outer side surface d2 on the opposite side, and the screw 36 is passed through the insertion hole 37 and screwed into the female screw holes 23a of the studs 23 and 23, and the lock body A and the display C The round seat 31 is opened and fixed to the door D.

錠本体Ａが開き扉Ｄに固定されると、レバーベース２０は、スタッド２３・２３が水平方向に横に並んだ位置、即ち、図７に示す対角線ｘ上に並んだ位置に固定される。従って、レバーベース２０に固定したインナープレート５０は、一組の固定凸部４５が、位置決め突起５０ａ・５０ａ間を結ぶ鉛直な対角線ｙに対して所定角度α傾斜した対角線ｍで結ばれる点対称の位置に配置されると共に、他組の固定凸部５５も、対角線ｙに対して図中反時計方向に所定角度α傾斜した対角線ｎで結ばれる点対称の位置に配置された状態で固定される。 When the lock body A is fixed to the opening door D, the lever base 20 is fixed to a position where the studs 23 and 23 are arranged horizontally in the horizontal direction, that is, a position where the stud base 23 is arranged on the diagonal line x shown in FIG. Therefore, the inner plate 50 fixed to the lever base 20 has a point-symmetrical structure in which a pair of fixed protrusions 45 are connected by a diagonal m inclined by a predetermined angle α with respect to a vertical diagonal y connecting the positioning protrusions 50a and 50a. In addition to being arranged at the position, the other fixed protrusions 55 are also fixed in a state of being arranged at point-symmetrical positions connected by a diagonal line n inclined by a predetermined angle α counterclockwise in the figure with respect to the diagonal line y. .

このレバーベース２０に対してロックレバー１０は、錠杆１５が起立した解錠姿勢の状態で、枢軸１９を中心として回転自在に組み付けられる。従って、ロックレバー１０に装着したアウターリング４０は、ロックレバー１０と一体に回転自在にレバーベース２０に支持され、可動凸部３５・３５のある外輪部２６が、図４に示すようにインナープレート５０と同一平面上に重なってジョイント１１を中心とする同軸上に配置される。すると、回転制御手段３０では、図７に示すように、錠杆１５が鉛直に起立した解錠姿勢の状態にロックレバー１０があるとき、アウターリング４０の可動凸部３５・３５が周回する回転軌道上にインナープレート５０の固定凸部４５・４５、５５・５５が位置し、その固定凸部４５・５５の間に可動凸部３５・３５が位置する。 The lock lever 10 is assembled to the lever base 20 so as to be rotatable about the pivot shaft 19 in an unlocked posture in which the lock rod 15 stands. Therefore, the outer ring 40 attached to the lock lever 10 is supported by the lever base 20 so as to be rotatable integrally with the lock lever 10, and the outer ring portion 26 having the movable convex portions 35 and 35 is formed as an inner plate as shown in FIG. 50 are arranged on the same plane with the joint 11 as the center. Then, in the rotation control means 30, as shown in FIG. 7, when the lock lever 10 is in the unlocked posture in which the lock rod 15 stands vertically, the rotation of the movable protrusions 35, 35 of the outer ring 40 rotates. The fixed convex portions 45, 45, 55, 55 of the inner plate 50 are positioned on the track, and the movable convex portions 35, 35 are positioned between the fixed convex portions 45, 55.

そこで、回転制御手段３０は、ロックレバー１０を、錠杆１５が対角線ｙに沿って鉛直に起立した解錠位置から施錠方向に自重により回転すると、図８に示すように、対角線ｙに対して所定角度β、例えば２０度回転したところで、アウターリング４０の可動凸部３５・３５の一側側面３５ａがそれぞれインナープレート５０の固定凸部４５の一側側面４５ａに当接し、ロックレバー１０の回転を停止する構造になっている（以下、このときのロックレバー１０の傾き位置を一時停止位置とする）。 Therefore, when the lock lever 10 is rotated by its own weight in the locking direction from the unlocked position where the lock rod 15 stands vertically along the diagonal line y, as shown in FIG. When rotated by a predetermined angle β, for example, 20 degrees, the one side surface 35a of the movable convex portion 35 of the outer ring 40 abuts on the one side surface 45a of the fixed convex portion 45 of the inner plate 50, and the lock lever 10 rotates. (Hereinafter, the tilt position of the lock lever 10 at this time is referred to as a temporary stop position).

しかも、回転制御手段３０は、図７に示すように、アウターリング４０には、可動凸部３５・３５を外輪部２６の軸線を中心とした点対称の位置に突設すると共に、インナープレート５０には、固定凸部４５・４５、５５・５５を、外周縁５０ｂの軸線（枢軸１９）を中心とした点対称の位置に突設するから、例えば錠本体Ａを開き扉の左右勝手の仕様を誤って組み付けてしまった場合でも、ロックレバー１０を、同じように錠杆１５が対角線ｙに沿って鉛直に起立した解錠位置から施錠方向に回転すると、対角線ｙに対して所定角度β回転したところで、アウターリング４０の可動凸部３５・３５の他側側面３５ｂがそれぞれインナープレート５０の固定凸部５５の一側側面５５ａに当接してロックレバー１０の回転を停止（一時停止）し、反対に、施錠位置から解錠方向に回転しても、対角線ｙに対して所定角度β回転したところで、アウターリング４０の可動凸部３５・３５の他側側面３５ｂがそれぞれインナープレート５０の固定凸部５５の一側側面５５ａに当接してロックレバー１０の回転を停止（一時停止）する構造になっている。 In addition, as shown in FIG. 7, the rotation control means 30 has movable convex portions 35, 35 projecting from the outer ring 40 at point-symmetric positions around the axis of the outer ring portion 26, and the inner plate 50. Since the fixed projections 45, 45, 55, 55 are projected at a point-symmetrical position about the axis (the pivot axis 19) of the outer peripheral edge 50b, for example, the lock body A is opened and the right and left hand specifications of the door are used. If the lock lever 10 is rotated in the locking direction from the unlocked position where the lock rod 15 stands vertically along the diagonal line y in the same manner, the lock lever 10 is rotated by a predetermined angle β with respect to the diagonal line y. Then, the other side surface 35b of the movable convex portions 35 and 35 of the outer ring 40 abuts on the one side surface 55a of the fixed convex portion 55 of the inner plate 50 to stop (temporarily stop) the rotation of the lock lever 10. On the contrary, even if it rotates in the unlocking direction from the locking position, the other side surface 35b of the outer ring 40 has the fixed protrusion of the inner plate 50 when it rotates by a predetermined angle β with respect to the diagonal line y. The rotation of the lock lever 10 is stopped (temporarily stopped) by contacting the one side surface 55a of the portion 55.

一方、開き扉Ｄの外側板面ｄ２において、図４、図５および図６に示すように、表示器Ｃの丸座３１には、嵌合穴３４に軸筒部３２ａを嵌め込んで表示板３２を冠着し、軸筒部３２ａの角穴８０に枢軸１９を嵌合し、錠本体Ａを、開き扉Ｄを挟んで表示板３２と一体に回転可能に連結する。それから、表示器Ｃは、表示板３２に表示カバー３３を被せる。そして、表示板３２の回転に応じて、表示窓３８から、開き扉Ｄの施錠状態を示す朱色部分又は解錠状態を示す青色部分を臨ませて、トイレの使用状態を外部に表示するようになっている。 On the other hand, on the outer side plate surface d2 of the opening door D, as shown in FIGS. 4, 5 and 6, the cylindrical portion 32a is fitted into the fitting hole 34 in the circular seat 31 of the display C, and the display plate 32, the pivot shaft 19 is fitted into the square hole 80 of the shaft cylinder portion 32a, and the lock main body A is rotatably connected to the display plate 32 with the opening door D interposed therebetween. Then, the display C places the display cover 33 on the display board 32. And according to rotation of the display board 32, the vermilion part which shows the locking state of the opening door D from the display window 38, or the blue part which shows the unlocking state is made to face, and the use condition of a toilet is displayed outside. It has become.

他方、開き扉Ｄの内側板面ｄ１には、取付筒部６５ａに止めねじ７５を通してねじ込み、ビス受け管６７を介してレバー受けＢを固定する。それから、取付筒部６５ａにはゴムキャップ６８を被せる。以って、本発明の打掛錠Ｒにおいて、レバー受けＢは、レバーベース２０に取付板部６０の円板部分６０ａを重ね合わせた状態で錠本体Ａに連結し、ロックレバー１０の錠杆１５が水平な施錠姿勢のときにレバー係止部６５のゴムキャップ６８に係止する高さ位置において、開き扉Ｄの戸先側端部の内側板面ｄ１に取り付ける。 On the other hand, the lever receiver B is fixed to the inner plate surface d 1 of the opening door D through the screw receiving pipe 67 by screwing the mounting cylinder portion 65 a through the set screw 75. Then, a rubber cap 68 is put on the mounting cylinder portion 65a. Therefore, in the latching lock R of the present invention, the lever receiver B is connected to the lock body A in a state where the disc portion 60a of the mounting plate 60 is superimposed on the lever base 20, and the lock lever 10 is locked. At the height position where 15 is locked to the rubber cap 68 of the lever locking portion 65 when the locking posture is horizontal, the lever 15 is attached to the inner plate surface d1 of the door end side end portion of the opening door D.

従って、本発明の打掛錠Ｒは、そのように施錠時に、ロックレバー１０の錠杆１５が係止する高さ位置において、レバー受けＢを、扉枠Ｆ側ではなく、ロックレバー１０と一緒に同じ開き扉Ｄの戸先側端部に取り付けるから、いちいち開き扉Ｄ側のロックレバー１０の高さ位置に合わせて、レバー受けＢを高さ調整しながら取り付ける必要がないために、それだけ設置作業に費やす手間と時間が少なく、簡単に組み付けることができる。 Therefore, the latching lock R of the present invention does not move the lever receiver B together with the lock lever 10 instead of the door frame F at the height position where the lock rod 15 of the lock lever 10 is locked. Since it is attached to the door end side end of the same opening door D, it is not necessary to adjust the height of the lock lever 10 on the opening door D side, and it is not necessary to adjust the height of the lever receiver B. Easy to assemble with less labor and time spent on work.

さて、打掛錠Ｒの使用時、例えば右勝手仕様の開き扉Ｄを回動して閉めると、そのまま開き扉Ｄの内側から、摘み部２５ｂを摘んでロックレバー１０を、図８中矢示する施錠方向に回転させる。例えば、いま錠杆１５が起立姿勢の解錠位置にあるロックレバー１０を施錠方向に回転させると、図２、図３および図８に示すように、回転途中の一時停止位置で、アウターリング４０の可動凸部３５の一側側面３５ａがインナープレート５０の固定凸部４５の一側側面４５ａに、いったん当接するが、そのとき、可動凸部３５と固定凸部４５の弾性力に抗して所定の大きさ以上の回転トルクでロックレバー１０を押し回すと、可動凸部３５と固定凸部４５が互いに弾性変形して可動凸部３５が固定凸部４５上を摺動しながら乗り越えてアウターリング４０を一体に回転させる。従って、ロックレバー１０は、図１および図９に示すように、錠杆１５が水平な横向きの施錠位置に回転し、錠杆１５の、扉枠Ｆとの間を跨いだ先端部１５ａ側を、レバー受けＢのレバー係止部６５に係止して開き扉Ｄを施錠する。 Now, when the latching lock R is used, for example, when the right-handed opening door D is turned and closed, the knob 25b is picked from the inside of the opening door D, and the lock lever 10 is indicated by an arrow in FIG. Rotate in the locking direction. For example, when the lock lever 10 in which the lock rod 15 is now in the unlocking position in the standing posture is rotated in the locking direction, as shown in FIGS. 2, 3, and 8, the outer ring 40 is at the temporary stop position during the rotation. The one side surface 35a of the movable convex portion 35 once abuts on the one side surface 45a of the fixed convex portion 45 of the inner plate 50, but at this time, against the elastic force of the movable convex portion 35 and the fixed convex portion 45. When the lock lever 10 is pushed and rotated with a rotational torque of a predetermined size or more, the movable convex portion 35 and the fixed convex portion 45 are elastically deformed with each other, and the movable convex portion 35 gets over the fixed convex portion 45 while sliding over the outer The ring 40 is rotated together. Accordingly, as shown in FIGS. 1 and 9, the lock lever 10 rotates the lock rod 15 to the horizontal horizontal locking position, and the front end portion 15 a side of the lock rod 15 across the door frame F is moved. The door D is locked by being locked to the lever locking portion 65 of the lever receiver B.

一方、開閉扉Ｄを開けるときは、反対の解錠方向にロックレバー１０を回転し、錠杆１５をレバー受けＢのレバー係止部６５から外して解錠する。ロックレバー１０を解錠方向に回転させると、今度は、回転途中の一時停止位置で、アウターリング４０の可動凸部３５の他側側面３５ｂがインナープレート５０の固定凸部４５の他側側面４５ｂに当接するが、そのとき、同じく可動凸部３５と固定凸部４５の弾性力に抗して所定の大きさ以上の回転トルクでロックレバー１０を押し回すと、可動凸部３５と固定凸部４５が互いに弾性変形して可動凸部３５が固定凸部４５上を摺動しながら乗り越えてアウターリング４０を一体に回転する。そして、ロックレバー１０を、アウターリング４０の可動凸部３５がインナープレート５０の固定凸部４５を乗り越えた位置で、少なくとも一時停止位置より解錠方向に離れた、開き扉Ｄの開閉の邪魔にならない解錠位置に回転させて、図１０に示すように開き扉Ｄを開ける。 On the other hand, when opening the opening / closing door D, the lock lever 10 is rotated in the opposite unlocking direction, and the lock rod 15 is detached from the lever locking portion 65 of the lever receiver B and unlocked. When the lock lever 10 is rotated in the unlocking direction, this time, the other side surface 35b of the movable convex portion 35 of the outer ring 40 is the other side surface 45b of the fixed convex portion 45 of the inner plate 50 at the temporary stop position in the middle of rotation. At that time, when the lock lever 10 is pushed and rotated with a rotational torque of a predetermined magnitude or more against the elastic force of the movable convex portion 35 and the fixed convex portion 45, the movable convex portion 35 and the fixed convex portion The elastic projections 45 are elastically deformed with each other, and the movable convex portion 35 rides on the fixed convex portion 45 while rotating and integrally rotates the outer ring 40. Then, the lock lever 10 is at a position where the movable convex portion 35 of the outer ring 40 gets over the fixed convex portion 45 of the inner plate 50, at least in the unlocking direction away from the temporary stop position, and obstructs the opening and closing of the opening door D. The door D is opened as shown in FIG.

ところで、図示打掛錠Ｒでは、図８に示すように、アウターリング４０の可動凸部３５の一側側面３５ａがインナープレート５０の固定凸部４５の一側側面４５ａに当接し、ロックレバー１０を、錠杆１５が鉛直に起立した解錠位置から施錠方向へ所定角度β傾斜した一時停止位置に保持しているときは、錠杆１５がレバー受けＢのレバー係止部６５から外れて解錠状態にあるから、開き扉Ｄを扉枠Ｆに強く衝突させるように閉めることができる。しかし、ロックレバー１０を一時停止位置に保持しているときには、可動凸部３５と固定凸部４５の弾性力に抗して所定の大きさ以上の回転トルクでロックレバー１０を施錠方向に押し回し、互いに弾性変位しながら可動凸部３５が固定凸部４５を乗り越えない限り、ロックレバー１０を施錠位置に回転させることができない。従って、ロックレバー１０を一時停止位置に位置させる一方、開き扉Ｄを扉枠Ｆに強く衝突するように閉めたとしても、そのときの衝撃によってロックレバー１０が施錠位置側へ回転することはない。その結果、トイレが不使用状態にあるにも拘わらず、いたずら等により開き扉Ｄが閉位置でロックされ、トイレ等を使用できなくなるのを未然に防止することができる。 By the way, in the illustrated locking lock R, as shown in FIG. 8, the one side surface 35 a of the movable projection 35 of the outer ring 40 abuts on the one side surface 45 a of the fixed projection 45 of the inner plate 50. Is held at a temporary stop position inclined at a predetermined angle β in the locking direction from the unlocked position where the lock rod 15 stands vertically, the lock rod 15 disengages from the lever locking portion 65 of the lever receiver B. Since it is in the locked state, the opening door D can be closed so as to strongly collide with the door frame F. However, when the lock lever 10 is held at the temporary stop position, the lock lever 10 is pushed in the locking direction with a rotational torque of a predetermined magnitude or more against the elastic force of the movable protrusion 35 and the fixed protrusion 45. The lock lever 10 cannot be rotated to the locked position unless the movable convex portion 35 gets over the fixed convex portion 45 while being elastically displaced from each other. Therefore, even if the lock lever 10 is positioned at the temporary stop position and the opening door D is closed so as to strongly collide with the door frame F, the lock lever 10 does not rotate to the locking position side due to the impact at that time. . As a result, it is possible to prevent the opening door D from being locked in the closed position due to mischief or the like, even though the toilet is not in use, so that the toilet cannot be used.

加えて、図示打掛錠Ｒでは、左右勝手仕様双方の開き扉Ｄに組み付けて使用できるように、回転制御手段３０は、図７に示すように、可動凸部３５を、アウターリング４０の外輪部２６の軸芯を中心とした点対称の位置の双方に突設すると共に、一対の固定凸部４５・５５も、インナープレート５０の外周縁５０ｂの軸芯を中心とした点対称の位置の双方に突設するから、図８に示すように、ロックレバー１０を、錠杆１５が対角線ｙに沿って鉛直に起立した解錠位置から施錠方向又は解錠方向に回転すると、それぞれ対角線ｙに対して所定角度β回転した４つの一時停止位置ｐ・ｑ・ｒ・ｓで、アウターリング４０の可動凸部３５・３５がインナープレート５０の固定凸部４５・５５の側面に当接してロックレバー１０の回転を停止させる構造になっている。そこで、解錠時に、錠杆１５が鉛直に起立した解錠位置にあるロックレバー１０に対し、仮に何らかの外力が加わって可動凸部３５と固定凸部４５・５５の弾性力に抗して所定の大きさ以上の回転トルクでロックレバー１０が解錠方向に強制回転し、例えば図１１に示すように、錠杆１５の先端部１５ａが開き扉Ｄの戸先側端部から扉枠Ｆ側に出っ張る一時停止位置ｓで停止し、開き扉Ｄの開閉動作の障害になることが考えられる。 In addition, in the illustrated locking lock R, the rotation control means 30 can be used by attaching the movable convex portion 35 to the outer ring of the outer ring 40 as shown in FIG. In addition to projecting at both point-symmetrical positions around the axis of the portion 26, the pair of fixed protrusions 45 and 55 are also point-symmetrical positions around the axis of the outer peripheral edge 50b of the inner plate 50. As shown in FIG. 8, when the lock lever 15 is rotated in the locking direction or the unlocking direction from the unlocking position where the lock rod 15 stands vertically along the diagonal line y, as shown in FIG. At four temporary stop positions p, q, r, and s rotated by a predetermined angle β with respect to the movable convex portions 35 and 35 of the outer ring 40 abut against the side surfaces of the fixed convex portions 45 and 55 of the inner plate 50 and the lock lever. Stop 10 rotation It has become an elephant. Therefore, at the time of unlocking, a certain external force is temporarily applied to the lock lever 10 in the unlocking position where the lock rod 15 stands vertically, and a predetermined amount is resisted against the elastic force of the movable convex portion 35 and the fixed convex portions 45 and 55. The lock lever 10 is forcibly rotated in the unlocking direction with a rotational torque greater than or equal to the size of the door. For example, as shown in FIG. It is conceivable that the operation stops at the temporary stop position s projecting on the door and becomes an obstacle to the opening / closing operation of the opening door D.

しかし、本発明の打掛錠Ｒでは、レバー受けＢを、ロックレバー１０の錠杆１５が施錠姿勢のときにレバー係止部６５に係止する高さ位置において、開き扉Ｄの戸先側端部の内側板面ｄ１に取り付けるから、解錠時、解錠時、ロックレバー１０を、可動凸部３５・３５と固定凸部４５・５５の弾性力に抗して所定の大きさ以上の回転トルクで起立した解錠位置から解錠方向に一時停止位置を越えて回転することがあると、図１２に示すように、ロックレバー１０の錠杆１５の後端部１５ｂをレバー受けＢのレバー係止部６５に係止してそれ以上の回転を規制し、これにより、錠杆１５の先端部１５ａが開き扉Ｄの戸先側端部から扉枠Ｆ側に出っ張って開き扉Ｄの開閉動作の障害になるのを防止することができる。 However, in the latching lock R of the present invention, the lever receiver B is at the height position where the lock lever 15 of the lock lever 10 is locked to the lever locking portion 65 when the lock lever 15 is in the locking posture. Since it is attached to the inner side plate surface d1 of the end portion, the lock lever 10 has a predetermined size or more against the elastic force of the movable convex portions 35 and 35 and the fixed convex portions 45 and 55 during unlocking and unlocking. If there is a case where the rotary lever is rotated from the unlocked position raised by the rotational torque beyond the temporary stop position in the unlocking direction, the rear end portion 15b of the lock lever 15 of the lock lever 10 is attached to the lever receiver B as shown in FIG. Locking to the lever locking portion 65 to restrict further rotation, the leading end portion 15a of the lock rod 15 protrudes from the door end side end portion of the opening door D to the door frame F side so that the opening door D It is possible to prevent an obstruction of the opening / closing operation.

以上の実施の形態では、回動式扉が開き扉Ｄである例を示したが、本発明の打掛錠は、開き扉に限らず、折戸など、その他の各種回動式扉を内側から施解錠する場合にも使用することができる。 In the above embodiment, an example in which the pivoting door is the opening door D has been shown. However, the hanging lock according to the present invention is not limited to the opening door, and other various pivoting doors such as folding doors are provided from the inside. It can also be used when locking and unlocking.

また、以上の実施の形態では、開き扉Ｄが外開き方式で戸尻側の扉枠に軸釣された構造であるため、打掛錠Ｒの錠本体Ａを、レバー受けＢと一緒に同じ開き扉Ｄに取り付けた例を示した。しかし、本発明は、反対に、開き扉が内開き方式で戸先側扉枠に軸釣された構造である場合には、打掛錠の錠本体を、レバー受けと一緒に同じ戸先側扉枠に取り付けて構成することもできる。 Moreover, in the above embodiment, since the opening door D is the structure which was axially fished by the door frame on the door butt side by the outside opening method, the lock main body A of the locking lock R is the same with the lever receiver B. The example attached to the hinged door D was shown. However, in the present invention, on the contrary, when the opening door is structured to be pivoted to the door-end side door frame by the inner opening method, the lock body of the locking lock is attached to the same door-end side together with the lever receiver. It can also be configured by being attached to a door frame.

When the self-weight rotates in the locking direction, the one side surface of the movable convex portions 35 of the outer ring 40 is fixed to the fixed convex portion 45 of the inner plate 50 at the temporary stop position. While the rotation of the lock lever 10 is stopped by abutting against one side surface of 45, 55, 55, the lock lever 10 is moved to the movable convex portions 35, 35 and the fixed convex portions 45, 45, 55, 55. The movable convex portions 35 and 35 and the fixed convex portions 45, 45, 55, and 55 are elastic to each other when pushed in the locking direction from the temporary stop position with a rotational torque of a predetermined magnitude or more against the elastic force of The movable convex portions 35 and 35 are deformed to move over the side surfaces of the fixed convex portions 45, 45, 55 and 55 and rotate the outer ring 40 integrally.

Tablets.

請求項１に記載の発明によれば、アウターリングの可動凸部の一側側面がインナープレートの固定凸部の一側側面に当接し、ロックレバーを、錠杆が鉛直に起立した解錠位置から施錠方向へ所定角度傾斜した一時停止位置に保持しているときは、少なくとも回動式扉は解錠状態にあるから、扉枠に強く衝突するように閉めることができる。しかし、ロックレバーを一時停止位置に保持しているときには、可動凸部と固定凸部の弾性力に抗して所定の大きさ以上の回転トルクでロックレバーを施錠方向に押し回し、互いに弾性変位しながら可動凸部が固定凸部を乗り越えない限り、ロックレバーを施錠位置に回転させることができない。従って、ロックレバーを一時停止位置に傾けて位置させる一方、回動式扉を扉枠に強く衝突するように閉めたとしても、そのときの衝撃によっては、ロックレバーが施錠位置側へ回転することはない。その結果、トイレが不使用状態にあるにも拘わらず、いたずら等により回動式扉が閉位置でロックされ、トイレ等を使用できなくなるのを未然に防止することができる。 According to the invention described in claim 1, one side surface of the movable protrusion of the outer ring abuts on one side surface of the securing boss of the inner plate, unlocked position the lock lever, lock lever is standing vertically When the door is held at a temporary stop position inclined at a predetermined angle in the locking direction, at least the rotary door is in the unlocked state, and can be closed so as to strongly collide with the door frame. However, when the lock lever is held at the temporary stop position, the lock lever is pushed in the locking direction with a rotational torque of a predetermined magnitude or more against the elastic force of the movable convex part and the fixed convex part, and elastically displaced from each other. However, the lock lever cannot be rotated to the locked position unless the movable convex portion gets over the fixed convex portion. Therefore, even if the lock lever is tilted to the temporary stop position and the rotary door is closed so as to strongly collide with the door frame, the lock lever rotates to the lock position side depending on the impact at that time. There is no. As a result, even though the toilet is not in use, it is possible to prevent the pivotable door from being locked in the closed position due to mischief or the like, so that the toilet can no longer be used.

加えて、請求項１に記載の発明では、左右勝手仕様双方の回動式扉又は扉枠に組み付けて使用できるように、回転制御手段は、可動凸部を、アウターリングの外輪部の軸芯を中心とした点対称の位置の双方に突設すると共に、一対の固定凸部も、インナープレートの外周縁の軸芯を中心とした点対称の位置の双方に突設するから、ロックレバーを、起立した解錠位置から施錠方向又は解錠方向に回転すると、それぞれ起立した解錠位置に対して所定角度回転した４つの一時停止位置で、アウターリングの可動凸部がインナープレートの固定凸部の側面に当接してロックレバーの回転を停止させる構造になっている。そこで、解錠時に、起立した解錠位置にあるロックレバーに対し、仮に何らかの外力が加わって可動凸部と固定凸部の弾性力に抗して所定の大きさ以上の回転トルクでロックレバーが解錠方向に強制回転し、先端部が回動式扉又は扉枠の戸先側端部から出っ張る一時停止位置で停止し、回動式扉の開閉動作の障害になることが考えられる。 In addition, in the invention according to claim 1 , the rotation control means has the movable convex portion as the axial center of the outer ring portion of the outer ring so that the rotary control means can be used by being assembled to both the right and left rotary doors or door frames. And a pair of fixed projections project from both point-symmetrical positions around the axis of the outer peripheral edge of the inner plate. When the upright unlocking position is rotated in the locking direction or the unlocking direction, the movable convex part of the outer ring is the fixed convex part of the inner plate at four temporary stop positions rotated by a predetermined angle with respect to the standing unlocking position. The structure is configured to stop the rotation of the lock lever by abutting against the side surface. Therefore, at the time of unlocking, some external force is applied to the lock lever in the standing unlocked position, and the lock lever is rotated with a rotational torque of a predetermined magnitude or more against the elastic force of the movable convex portion and the fixed convex portion. Forcibly rotating in the unlocking direction and stopping at a temporary stop position where the tip end protrudes from the end of the door or the door frame side of the door, which may hinder the opening / closing operation of the door.

しかし、本発明の打掛錠Ｒでは、レバー受けＢを、ロックレバー１０の錠杆１５が施錠姿勢のときにレバー係止部６５に係止する高さ位置において、開き扉Ｄの戸先側端部の内側板面ｄ１に取り付けるから、解錠時、ロックレバー１０を、可動凸部３５・３５と固定凸部４５・５５の弾性力に抗して所定の大きさ以上の回転トルクで起立した解錠位置から解錠方向に一時停止位置を越えて回転することがあると、図１２に示すように、ロックレバー１０の錠杆１５の後端部１５ｂをレバー受けＢのレバー係止部６５に係止してそれ以上の回転を規制し、これにより、錠杆１５の先端部１５ａが開き扉Ｄの戸先側端部から扉枠Ｆ側に出っ張って開き扉Ｄの開閉動作の障害になるのを防止することができる。 However, in the latching lock R of the present invention, the lever receiver B is at the height position where the lock lever 15 of the lock lever 10 is locked to the lever locking portion 65 when the lock lever 15 is in the locking posture. Since it is attached to the inner plate surface d1 at the end, when unlocking, the lock lever 10 stands up with a rotational torque of a predetermined magnitude or more against the elastic force of the movable convex portions 35 and 35 and the fixed convex portions 45 and 55. If there is a rotation beyond the temporary stop position in the unlocking direction from the unlocked position, the rear end portion 15b of the lock lever 15 of the lock lever 10 is connected to the lever engaging portion of the lever receiver B as shown in FIG. 65 is locked to restrict further rotation, and as a result, the front end portion 15a of the lock rod 15 protrudes from the door end side end portion of the opening door D to the door frame F side, thereby obstructing the opening / closing operation of the opening door D. Can be prevented.
