【課題を解決するための手段】 以下、添付図面中の参照番号を用いて説明 すると、本考案の抜差型扉用ロックハンドル装置は、扉1に固着される受座本体 3と、受座本体3の先端に連設される取付フランジ4と、受座本体3の後端に連 設された軸受筒部5に回転可能に支持される施錠軸6と、施錠軸6の前端に連設 される連結フランジ7と、連結フランジ7に設けられた挿入口8に作動突子10 が着脱自在に挿入されるキーハンドル9と、連結フランジ7の後端面6aの凹部 11に回転不能に嵌め込まれ、キーハンドル9の作動突子10が着脱自在に挿入 されるハンドル係脱溝13を先端側12aに設けた錠止部材12と、錠止部材1 2の基端側12bに設けた錠止突起14と、錠止突起14が係脱する錠止受部1 5と、凹部11の内底面11aと錠止部材12の前端面12c間に挿入された圧 縮コイルバネ16と、受座本体2の基端側の錠前収納部17に取付収納される錠 前ユニット18と、錠前ユニット18のロータ19に連動して、受溝21に係脱 するロックプレート20とから成り、作動突子10を挿入口8からハンドル係脱 溝13に挿入した時、前記圧縮コイルバネ16の摺動付勢に抗して錠止部材12 が前記凹部11内に後退する。[MEANS FOR SOLVING THE PROBLEMS] Hereinafter, referring to the reference numbers in the accompanying drawings, a lock handle device for a slip-on door according to the present invention comprises a seat body 3 fixed to the door 1 and a seat. A mounting flange 4 connected to the front end of the main body 3, a locking shaft 6 rotatably supported by a bearing tubular part 5 connected to the rear end of the seat body 3, and a front end of the locking shaft 6. And the key handle 9 into which the operating protrusion 10 is detachably inserted in the insertion opening 8 provided in the connecting flange 7, and the recessed portion 11 of the rear end face 6a of the connecting flange 7 which is non-rotatably fitted. A locking member 12 provided with a handle engaging / disengaging groove 13 on the distal end side 12a into which the actuating protrusion 10 of the key handle 9 is detachably inserted, and a locking projection provided on the proximal end side 12b of the locking member 12 14 and the lock receiving portion 15 with which the lock protrusion 14 disengages, and the inside of the recess 11. The compression coil spring 16 inserted between the bottom surface 11a and the front end face 12c of the lock member 12, the lock unit 18 mounted and stored in the lock storage unit 17 on the base end side of the seat body 2, and the lock unit 18 It is composed of a lock plate 20 which engages and disengages with the receiving groove 21 in conjunction with the rotor 19, and when the actuating protrusion 10 is inserted into the handle engaging and disengaging groove 13 from the insertion opening 8, the sliding bias of the compression coil spring 16 is exerted. On the contrary, the locking member 12 retracts into the recess 11.
【0006】 キーハンドル9が挿入口8に挿入されていない時には、錠止部材12は圧縮コ イルバネによって取付フランジ4側に摺動付勢され、錠止部材12の錠止突起1 4は取付フランジ4の錠止受部15に没入し、施錠軸6は受座本体3に対して施 錠されている。また、止め金板22は受金23と係合した施錠位置にあり、扉1 は固定枠体2に対し締め付け施錠されている。錠前ユニット18に所定の鍵24 を挿入してロータ19を施錠方向に回転させると、ロータ19に連動してロック プレート20が施錠方向に移動し、受溝21に係合する。これによって、扉1は 固定枠体2に大して本締め錠止される。When the key handle 9 is not inserted into the insertion opening 8, the locking member 12 is slid and biased toward the mounting flange 4 by the compression coil spring, and the locking protrusion 14 of the locking member 12 is mounted on the mounting flange 4. 4, the lock shaft 6 is locked to the seat main body 3. Further, the stopper plate 22 is in a locked position in which the stopper plate 23 is engaged, and the door 1 is tightened and locked to the fixed frame body 2. When a predetermined key 24 is inserted into the lock unit 18 and the rotor 19 is rotated in the locking direction, the lock plate 20 moves in the locking direction in conjunction with the rotor 19 and engages with the receiving groove 21. As a result, the door 1 is locked to the fixed frame 2 by a large amount.
【0007】 キーハンドル9の作動突子10を挿入口8からハンドル係脱溝13に挿入し、 圧縮コイルバネ16の摺動付勢に抗して錠止部材12を凹部11内に後退させ、 施錠軸6の施錠を解除し、鍵24によってロータ19を解錠方向に回転操作し、 ロックプレート20を受溝21から離脱させた後、キーハンドル9を握って施錠 軸6を解錠方向に回転操作すると、止め金板22が受金23から離脱して、固定 枠体2に対する扉1の施錠が解除され、扉1はキーハンドル9を手前に引くこと によって解放される。The operating protrusion 10 of the key handle 9 is inserted into the handle engaging / disengaging groove 13 from the insertion opening 8, and the locking member 12 is retracted into the recess 11 against the sliding bias of the compression coil spring 16, After unlocking the shaft 6, the rotor 24 is rotated in the unlocking direction by the key 24 to disengage the lock plate 20 from the receiving groove 21, and then the key handle 9 is gripped to rotate the shaft 6 in the unlocking direction. When operated, the stopper plate 22 is separated from the receiving plate 23, the locking of the door 1 with respect to the fixed frame body 2 is released, and the door 1 is released by pulling the key handle 9 toward you.

【考案の実施の形態】 図示の実施例では、受座本体3の背面側の軸受筒部 5に後端部を嵌挿した施錠軸6は、施錠軸6の後端側に装着したC−リング25 によって抜け止め防止されている。施錠軸6の中間部と軸受筒部5の内壁面間に は防水用O−リング26を挿入してあり、止め金板22は角孔27にて施錠軸の 後端角軸部28に嵌合され、後端角軸部28の螺子孔29に螺合したボルト30 によって施錠軸6に締め付け固定されている。BEST MODE FOR CARRYING OUT THE INVENTION In the illustrated embodiment, a locking shaft 6 having a rear end portion fitted and inserted into a bearing cylinder portion 5 on the rear side of a seat body 3 has a C-axis mounted on the rear end side of the locking shaft 6. The ring 25 prevents it from coming off. A waterproof O-ring 26 is inserted between the intermediate portion of the locking shaft 6 and the inner wall surface of the bearing tubular portion 5, and the stopper plate 22 is fitted into the rear end angular shaft portion 28 of the locking shaft through the square hole 27. The bolt 30 is screwed into the screw hole 29 of the rear end angular shaft portion 28 and is fastened and fixed to the locking shaft 6.
【0009】 圧縮コイルバネ16は連結フランジ7の凹部11の内底面11aと錠止部材1 2の前端面10c間に挿入されている。キーハンドル9を挿入しない施錠状態に おいて、錠止部材12の錠止突起14が圧縮コイルバネ16の付勢によって錠止 受部15に係合するため、施錠軸6は錠前ユニット18によって本締め錠止しな くても受座本体3に対して回転規制されている。The compression coil spring 16 is inserted between the inner bottom surface 11 a of the recess 11 of the connecting flange 7 and the front end surface 10 c of the locking member 12. In the locked state in which the key handle 9 is not inserted, the locking projection 14 of the locking member 12 engages with the lock receiving portion 15 by the bias of the compression coil spring 16, so that the locking shaft 6 is fully tightened by the lock unit 18. Even if it is not locked, the rotation of the seat body 3 is restricted.
【0010】 取付フランジ4の前端面には、回転角度規制用円弧溝31を円周方向に設けて あり、連結フランジ7の後端面に突設した規制突起32が円弧溝31に嵌め込ま れている。規制突起32が円弧溝31の左右各端部31a、bに当接することに よって、キーハンドル9の回転角度は65度に規制されている。On the front end face of the mounting flange 4, a rotation angle regulating arc groove 31 is provided in the circumferential direction, and a regulation projection 32 protruding from the rear end face of the connecting flange 7 is fitted into the arc groove 31. . The rotation angle of the key handle 9 is regulated to 65 degrees by the regulation projection 32 coming into contact with the left and right end portions 31a and 31b of the circular arc groove 31.
【0011】 受座本体3の先端部にナイロンプラスチック製の保護スペイサー33を設けて あり、キーハンドル9を挿入する時、接触による作動突子の損傷を防止する。軸 受筒部5は扉1の受孔34に嵌挿され、受座本体3の背面側の位置決め突起35 a、bは扉1の位置決め穴36a、bに嵌め込まれる。軸受筒部5の外周面螺子 部37にナット38を螺合し、受座本体3は扉1との間に防水用パッキング39 を挟持した状態で扉1に締め付け固定される。A protective spacer 33 made of nylon plastic is provided at the tip of the seat body 3 to prevent damage to the operating protrusion due to contact when the key handle 9 is inserted. The shaft receiving cylinder portion 5 is fitted into the receiving hole 34 of the door 1, and the positioning protrusions 35 a and 35 b on the rear surface side of the seat body 3 are fitted into the positioning holes 36 a and 36 b of the door 1. A nut 38 is screwed onto the outer peripheral surface screw portion 37 of the bearing tube portion 5, and the seat body 3 is clamped and fixed to the door 1 with the waterproof packing 39 being sandwiched between the seat body 3 and the door 1.
【0012】 錠前ユニット18は錠前収納部17の前面側の空洞部40に回転不能に取付収 納されている。鍵24によって固定本体41に対するロータ19の錠止を解除し 、鍵24によってロータ19を解錠方向に回転させると、連動筒42が同方向に 回転し、駆動突起43が従動溝44の溝壁面を押すことによって、ロックプレー ト20のカム板部45が解錠方向に摺動する。これによってロックプレート20 の錠止突起46が受溝21から脱出して、キーハンドル9の回転操作が可能にな る。The lock unit 18 is non-rotatably attached and stored in the cavity 40 on the front side of the lock storage unit 17. When the lock of the rotor 19 with respect to the fixed main body 41 is unlocked by the key 24 and the rotor 19 is rotated in the unlocking direction by the key 24, the interlocking cylinder 42 rotates in the same direction, and the drive projection 43 causes the groove wall surface of the driven groove 44. By pressing, the cam plate portion 45 of the lock plate 20 slides in the unlocking direction. As a result, the locking projection 46 of the lock plate 20 comes out of the receiving groove 21, and the key handle 9 can be rotated.
