Description

本発明は、倉庫などに使用される扉や建具の気密性や防音性を考慮した扉等に用いられるロックハンドル装置に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock handle device used for doors and fittings used in warehouses, etc. in consideration of airtightness and soundproofing.

ロックハンドル装置は、扉の内外を貫通するハンドル回動軸の両端に内外の操作ハンドルが固定され、閉扉時に、一方の操作ハンドルの操作でロック係合部材が扉より突出して戸口枠に設けられたロック受部に係合してロック状態とする(例えば、特許文献1参照)。 In the lock handle device, the inner and outer operation handles are fixed to both ends of a handle rotation shaft passing through the inside and outside of the door, and when the door is closed, the lock engaging member protrudes from the door and is provided on the door frame by operating one of the operation handles. It is locked by engaging with the lock receiving portion (see, for example, Patent Document 1).

特許文献1に開示されたロックハンドル装置は、施錠用ハンドル(操作ハンドル)が扉の内外にあり、それぞれハンドル支持ケースに支持されて扉に装備されている。
扉の内外を貫通するハンドル軸(ハンドル回動軸)が内外の施錠用ハンドルを連結して一体に支持しており、同ハンドル軸にロック棒(ロック係合部材)が一体に嵌合している。
In the lock handle device disclosed in Patent Literature 1, locking handles (operating handles) are provided inside and outside the door, and are mounted on the door while being supported by a handle support case.
A handle shaft (handle rotation shaft) passing through the inside and outside of the door connects and integrally supports the inside and outside locking handles, and a lock bar (lock engaging member) is integrally fitted to the handle shaft. there is

閉扉時に、一方の施錠用ハンドルをロック操作すると、ハンドル軸の回動でロック棒がハンドル支持ケースから出て戸先より外側に突出し、戸口枠に設けられた受け溝(ロック受部)に挿入されてロック状態となる。 When one of the locking handles is operated to lock the door when the door is closed, the lock rod comes out of the handle support case due to the rotation of the handle shaft, protrudes outside the door tip, and is inserted into the receiving groove (lock receiving part) provided in the door frame. locked.

施錠用ハンドルがロック位置にあってロック状態にあるときは、ロック棒が受け溝に挿入して受け溝の奥の窪みに掛合することで、振動があっても外れることがないようにしている。 When the locking handle is in the locked position and in the locked state, the lock bar is inserted into the receiving groove and engages with the recess at the back of the receiving groove so that it will not come off even if there is vibration. .

しかし、特許文献1に開示されたロックハンドル装置は、施錠用ハンドルがロック解除されているときに、ロック棒がハンドル支持ケースに収納して戸口枠の受け溝に挿入できる位置に突出しないように規制する手段は開示されていないので、開扉時には施錠用ハンドルおよびロック棒は回動自由状態にある。 However, in the lock handle device disclosed in Patent Document 1, when the locking handle is unlocked, the lock rod is accommodated in the handle support case and does not protrude to a position where it can be inserted into the receiving groove of the door frame. Since no restricting means is disclosed, the locking handle and lock bar are free to rotate when the door is opened.

したがって、開扉時には、ロック棒が受け溝に挿入できる位置に突出する可能性があり、ロック棒の突出に気付かずに扉を閉めようとすると、ロック棒が戸口枠に衝突してロック棒や戸口枠に損傷を与えてしまう惧れがある。
また、扉より突出したロック棒に衣服等を引っ掛けたりする不具合もある。
Therefore, when the door is opened, the lock bar may protrude to a position where it can be inserted into the receiving groove. There is a risk of damaging the door frame.
In addition, there is also a problem that clothes or the like are caught on the locking rod protruding from the door.

そこで、操作ハンドルをロック解除位置で回動を規制して、開扉時にロック係合部材が突出して戸口枠に衝突することを回避した例がある(特許文献2参照)。 Therefore, there is an example of preventing the lock engaging member from projecting and colliding with the doorway frame when the door is opened by restricting the rotation of the operating handle at the unlocked position (see Patent Document 2).

特許文献2に開示された操作ハンドルは、扉に固定された軸部の外周に回動自在に嵌合され、操作ハンドルに設けられたハンドル部固定シャフトがロック位置とロック解除位置で軸部に形成された凹部に係合することで、操作ハンドルの回動を規制するものである。 The operating handle disclosed in Patent Document 2 is rotatably fitted to the outer periphery of a shaft portion fixed to a door, and a handle portion fixing shaft provided in the operating handle is attached to the shaft portion at a locked position and an unlocked position. The rotation of the operating handle is restricted by engaging with the formed concave portion.

しかし、特許文献2に開示された操作ハンドルは、扉の内外側面の一側面にのみ取り付けられる構造のものであり、内外一対の操作ハンドルが共通の回動軸で連結されて、いずれの操作ハンドルを操作してもロックおよびロック解除ができる本発明の構造とは、基本的に構造が異なるので、特許文献2に開示された上記操作ハンドルの回動規制の構成は全く適用することができない。 However, the operating handle disclosed in Patent Document 2 is of a structure that is attached only to one side of the inner and outer side surfaces of the door, and a pair of inner and outer operating handles are connected by a common pivot shaft so that either operating handle Since the structure is fundamentally different from the structure of the present invention in which locking and unlocking can be performed by operating , the structure for restricting rotation of the operating handle disclosed in Patent Document 2 cannot be applied at all.

本発明は、かかる点に鑑みなされたもので、その目的とする処は、開扉時にロック係合部材がロック受部に係合できる位置に突出することを防止した内外一対の操作ハンドルを備えたロックハンドル装置を供する点にある。 SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and its object is to provide a pair of inner and outer operating handles that prevent the lock engaging member from protruding to a position where the lock receiving portion can be engaged when the door is opened. The purpose is to provide a lock handle device that is more efficient.

In order to achieve the above object, the present invention
a swingable door for opening and closing an opening in the doorway frame;
a pair of inner and outer pedestals respectively fixed to the inner and outer side surfaces of the door;
a pair of cylindrical members rotatably supported by the pair of pedestals with their respective rotation center axes coaxial;
a handle rotation shaft having both ends fitted to the pair of cylindrical members and passing through the door along the rotation center axis;
a pair of inner and outer operation handles each having a rotation base fixed to each of the pair of cylindrical members and rotated along each of the pair of pedestals;
a lock engaging member protruding from a rotation base of at least one of the operating handles;
When the door is closed, by rotating the operation handle to the lock position, the lock engaging member engages with a lock receiving portion provided on the doorway frame to establish a locked state,
A lock handle device in which the lock engaging member is disengaged from the lock receiving portion to be in an unlocked state by rotating the operating handle to an unlocked position,
a slide bar axially slidably penetrating the center of the handle rotation shaft;
slide bar biasing means for biasing the slide bar in one axial direction;
a locking member that axially moves together with the slide bar and rotates together with the cylindrical member;
a trigger operating member provided on each of the pair of operating handles;
a trigger conversion mechanism that converts the actuation of the trigger operating member into axial movement of the slide bar against the biasing force of the slide bar biasing means;
When the operating handle is at the locked position or the unlocked position, the locking member, which is moved in the axial direction by being biased by the slide bar biasing means, is locked to the pedestal to restrict its rotation. Provided is a lock handle device characterized by forming a locked portion that

この構成によれば、操作ハンドルがロック位置またはロック解除位置にあるときに、スライドバー付勢手段により付勢されてスライドバーが一方向に移動し、ともに係止部材が移動して台座に形成された被係止部に係止して回動が規制されることで、係止部材とともに筒状部材を介して操作ハンドルの回動が規制される。
トリガー操作部材の操作で、トリガー変換機構を介してスライドバーがスライドバー付勢手段の付勢力に抗して他方向に移動し、ともに係止部材が移動して被係止部との係止が解除されることで、係止部材とともに筒状部材を介して操作ハンドルの回動規制が解除される。
According to this configuration, when the operating handle is at the locked position or the unlocked position, the slide bar is biased by the slide bar biasing means to move in one direction, and the locking member moves together to form the slide bar on the pedestal. Rotation of the operating handle is restricted through the tubular member together with the locking member by being locked to the locked portion and restricted from rotating.
By operating the trigger operating member, the slide bar moves in the other direction against the biasing force of the slide bar biasing means via the trigger conversion mechanism, and the locking member moves together to lock the locked portion. is released, the rotation restriction of the operating handle is released through the cylindrical member together with the locking member.

閉扉時に操作ハンドルがロック位置にあってロック状態にあるときに、トリガー操作部材を操作して係止部材の被係止部との係止を解除して、操作ハンドルをロック解除位置まで回動してロックを解除すると、スライドバー付勢手段により係止部材が移動して台座に形成された被係止部に係止して操作ハンドルの回動が規制されるので、扉を開いても操作ハンドルはロック解除位置に維持され、ロック係合部材は戸口枠のロック受部から抜けた状態に維持され、すなわちロック係合部材がロック受部に係合できる位置に突出することが防止され、ロック係合部材が戸口枠に衝突してロック係合部材や戸口枠に損傷を与えることはない。 When the operating handle is in the locked position and in the locked state when the door is closed, the trigger operating member is operated to unlock the locking member from the locked portion, and the operating handle is rotated to the unlocked position. When the lock is released, the locking member is moved by the slide bar urging means and locked to the locked portion formed on the pedestal, thereby restricting the rotation of the operating handle. The operating handle is maintained at the unlocked position, and the lock engaging member is maintained in a state of being disengaged from the lock receiving portion of the door frame. , the lock engaging member will not collide with the door frame and damage the lock engaging member and the door frame.

また、操作ハンドルがロック位置にあってロック係合部材がロック受部に係合してロック状態にあるときは、係止部材が被係止部に係止して、トリガー操作部材を操作しない限り操作ハンドルの回動が規制されるので、不用意に操作ハンドルを回動したり、衝撃や振動により操作ハンドルが回動してロックが解除されるようなことを防止することができる。 Further, when the operating handle is in the locked position and the lock engaging member is engaged with the lock receiving portion to be in the locked state, the locking member is locked to the locked portion and the trigger operating member is not operated. Since the rotation of the operation handle is restricted as long as possible, it is possible to prevent the operation handle from being unintentionally rotated or from being unlocked due to the rotation of the operation handle due to impact or vibration.

筒状部材とともに回動し、かつ回動中心軸の軸方向に移動可能な係止部材が、操作ハンドルのロック位置とロック解除位置の各位置で、スライドバー付勢手段の付勢力により移動して被係止部に係止することができ、係止部材が被係止部に係止した状態で、トリガー操作部材を操作すると、トリガー変換機構を介してスライドバーが係止部材と一体にスライドバー付勢手段の付勢力に抗して移動して係止部材の被係止部との係止を解除して、操作ハンドルの回動を許可するので、スライドバー付勢手段をこのように使用することで、簡単な構造で、トリガー操作部材の操作性を向上させることができる。 A locking member that rotates together with the cylindrical member and is movable in the axial direction of the central axis of rotation is moved by the biasing force of the slide bar biasing means between the lock position and the unlock position of the operating handle. When the trigger operating member is operated in a state where the locking member is locked to the locked portion, the slide bar and the locking member are integrated with each other via the trigger conversion mechanism. The slide bar urging means is moved against the urging force of the slide bar urging means to release the engagement of the locking member with the engaged portion, thereby permitting the rotation of the operating handle. , the operability of the trigger operation member can be improved with a simple structure.

なお、係止ピン28は、抜止め部材28sにより円柱体部27に抜け止めされる(図8参照)。
When the extension member 25 is assembled, a locking pin 28 as a locking member is passed through the through hole 27h of the cylindrical body portion 27. As shown in FIG.
That is, when the cylindrical member 12 is passed through the circular hole 16ah of the rotating base portion 16a of the inner operating handle 15, the extension member 25 is inserted into the cylindrical member 12, and the through hole 27h of the cylindrical body portion 27 is made cylindrical.

内側台座11の円筒状支持部11aの円弧溝11aaは、両端に軸方向により深い被係止穴11ac,11aoが形成されているので、係止ピン28は、円弧溝11aaと同じ軸方向位置にあるときに円弧溝11aaの角度範囲内で回動でき、円弧溝11aaの両端の被係止穴11ac,11aoのいずれかに対応する回動位置にあるときに、長孔12eの軸方向幅内で延長部材25(およびスライドバー33)とともに軸方向に移動でき、係止ピン28が軸方向に移動して被係止穴11ac,11aoのいずれかに係止すると、円筒状部材12(および内側操作ハンドル15)とともに回動が規制される。 The circular arc groove 11aa of the cylindrical support portion 11a of the inner pedestal 11 is formed with locking holes 11ac and 11ao deeper in the axial direction at both ends, so that the locking pin 28 is positioned at the same axial position as the circular arc groove 11aa. When it can rotate within the angle range of the arcuate groove 11aa at a certain time, and when it is in the rotation position corresponding to either of the locked holes 11ac and 11ao at both ends of the arcuate groove 11aa, it is within the axial width of the long hole 12e. can move in the axial direction together with the extension member 25 (and the slide bar 33).

7 to 9 show a state in which the inner operating handle 15 and the outer operating handle 55 are at the unlocked position Po and the trigger operating members 21, 61 are not operated.
In FIG. 2, the inner operating handle 15 is in the unlocked position Po, indicated by a two-dot chain line.

内側操作ハンドル15の回動基部16aから突設されたロックローラ18は、戸先8aから離れる扉8の内側の方に没入してロック解除状態にある。
内側操作ハンドル15と外側操作ハンドル55を連結するハンドル回動軸31の中心軸孔31cを貫通するスライドバー33は、両端に連結された延長部材25,65とともに、圧縮コイルばね35により付勢されて外側操作ハンドル55側に移動した位置にある。
A lock roller 18 protruding from the rotation base portion 16a of the inner operating handle 15 is retracted toward the inner side of the door 8 away from the door tip 8a and is in an unlocked state.
A slide bar 33 passing through a central shaft hole 31c of a handle rotating shaft 31 connecting the inner operating handle 15 and the outer operating handle 55 is biased by a compression coil spring 35 together with extension members 25 and 65 connected to both ends. is moved to the outer operating handle 55 side.

図9を参照して、トリガー操作部材21は操作されておらず、ねじりコイルばね21sにより下方に揺動付勢されてグリップカバー17,17の下部開口から下方に大きく突出されており、リンク部材22を介してトリガー作動部材23は回動中心軸Lcから離れる方向に移動して、図7に示されるように、トリガー作動部材23の先端部のローラ24は、外側操作ハンドル55側に移動した延長部材25の円錐体部26の円錐面26tの径の大きい外周縁近傍に接している。 Referring to FIG. 9, the trigger operating member 21 is not operated and is urged downward by a torsion coil spring 21s to protrude greatly downward from the lower openings of the grip covers 17, 17, and the link member 22, the trigger operating member 23 moves away from the rotation center axis Lc, and as shown in FIG. The conical surface 26t of the conical portion 26 of the extension member 25 is in contact with the vicinity of the large-diameter outer peripheral edge.

同様に、外側操作ハンドル55もロック解除位置Poにあり、トリガー操作部材61は操作されておらず、よってトリガー操作部材61は下方に揺動付勢されて、リンク部材62を介して回動中心軸Lcから離れる方向に移動したトリガー作動部材63の先端部のローラ64は、延長部材65の円錐体部66の円錐面66tの径の大きい外周縁近傍に接している(図7参照)。 Similarly, the outer operating handle 55 is also at the lock release position Po, and the trigger operating member 61 is not operated. The roller 64 at the tip of the trigger actuating member 63 moved away from the axis Lc is in contact with the large-diameter outer peripheral edge of the conical surface 66t of the conical portion 66 of the extension member 65 (see FIG. 7).

内側操作ハンドル15がロック解除位置Poにあって、延長部材25が圧縮コイルばね35により付勢されて外側操作ハンドル55側に移動した位置にあるので、延長部材25の円柱体部27を貫通し、かつ円筒状部材12の長孔12eを貫通した係止ピン28は、両端28e,28eが内側台座11の円筒状支持部11aの内周面の開口端側に形成された円弧溝11aa,11aaの一端の被係止穴11ao,11aoに嵌入して係止して(図8参照)、係止ピン28の回動が規制されている。 Since the inner operating handle 15 is at the unlocking position Po and the extension member 25 is biased by the compression coil spring 35 and moved toward the outer operating handle 55, the cylindrical body portion 27 of the extension member 25 is penetrated. Also, the locking pin 28 passing through the long hole 12e of the cylindrical member 12 has both ends 28e, 28e formed in circular arc grooves 11aa, 11aa formed on the open end side of the inner peripheral surface of the cylindrical support portion 11a of the inner pedestal 11. The engaging holes 11ao, 11ao at one end of the locking pin 28 are fitted into and locked (see FIG. 8), and the rotation of the locking pin 28 is restricted.

そのため、係止ピン28が長孔12eを貫通する円筒状部材12も回動が規制され、円筒状部材12と一体の内側操作ハンドル15の回動も規制される。
さらには、ハンドル回動軸31および円筒状部材52を介して外側操作ハンドル55の回動も規制される。
Therefore, the rotation of the cylindrical member 12 through which the locking pin 28 passes through the long hole 12e is also restricted, and the rotation of the inner operating handle 15 integrated with the cylindrical member 12 is also restricted.
Furthermore, rotation of the outer operating handle 55 is also restricted via the handle rotating shaft 31 and the cylindrical member 52 .

なお、ハンドル回動軸31に嵌着された回動規制部材32の突起係止部32pが、外側台座51の取付け座部51bに形成された2本のストッパリブ51bc,51boのうち一方のストッパリブ51boに当接して、ハンドル回動軸31の過度の回動は規制される。 Note that the projection engaging portion 32p of the rotation restricting member 32 fitted to the handle rotation shaft 31 is attached to one stopper rib 51bo of the two stopper ribs 51bc and 51bo formed on the mounting seat portion 51b of the outer pedestal 51. , the excessive rotation of the handle rotation shaft 31 is restricted.

したがって、内側操作ハンドル15と外側操作ハンドル55は、ロック解除位置Poに維持されて回動を規制されるので、ロックローラ18がロック受部19に係合できる位置に突出することが防止され、閉扉したときにロックローラ18が戸口枠5に衝突してロックローラ18や戸口枠5に損傷を与えることはない。 Therefore, since the inner operating handle 15 and the outer operating handle 55 are maintained at the unlocked position Po and their rotation is restricted, the lock roller 18 is prevented from protruding to a position where it can be engaged with the lock receiving portion 19. When the door is closed, the lock roller 18 does not collide with the door frame 5 to damage the lock roller 18 and the door frame 5.例文帳に追加

内側操作ハンドル15と外側操作ハンドル55が、ロック解除位置Poにあるときに、扉8を閉め、内側操作ハンドル15のハンドルグリップ部16bを掴み、指でトリガー操作部材21を握り、トリガー操作部材21を揺動操作すると、図10に示されるように、トリガー操作部材21が上方に揺動し、リンク部材22を介してトリガー作動部材23が押し出され、トリガー作動部材23の先端部のローラ24が延長部材25の円錐体部26の円錐面26tを転動しながら押圧し、円錐体部26を円柱体部27およびスライドバー33とともに、圧縮コイルばね35のばね力に抗して外側操作ハンドル55と反対側に移動する(図11参照)。 When the inner operating handle 15 and the outer operating handle 55 are at the unlocking position Po, the door 8 is closed, the handle grip portion 16b of the inner operating handle 15 is grasped, the trigger operating member 21 is grasped with fingers, and the trigger operating member 21 is pulled. 10, the trigger operating member 21 swings upward, the trigger operating member 23 is pushed out through the link member 22, and the roller 24 at the tip of the trigger operating member 23 is pushed out. The conical surface 26t of the conical portion 26 of the extension member 25 is pressed while rolling, and the conical portion 26, together with the cylindrical body portion 27 and the slide bar 33, is pushed against the spring force of the compression coil spring 35 to move the outer operating handle 55. and move to the opposite side (see FIG. 11).

また、外側操作ハンドル55側のトリガー操作部材61を揺動操作すると、リンク部材62を介してトリガー作動部材63が押し出されることで、トリガー作動部材63の先端部のローラ64が延長部材65の円錐体部66の円錐面66tを転動しながら押圧し、円錐体部66を円板部67およびスライドバー33とともに圧縮コイルばね35のばね力に抗して内側操作ハンドル15側に移動する(図12参照)。 Further, when the trigger operating member 61 on the outer operating handle 55 side is operated to swing, the trigger operating member 63 is pushed out through the link member 62, so that the roller 64 at the tip of the trigger operating member 63 moves into the conical shape of the extension member 65. The conical surface 66t of the body portion 66 is pressed while rolling, and the conical portion 66, together with the disk portion 67 and the slide bar 33, is moved toward the inner operation handle 15 against the spring force of the compression coil spring 35 (Fig. 12).

円柱体部27が圧縮コイルばね35のばね力に抗して移動すると、円柱体部27を貫通する係止ピン28は、その両端28e,28eが内側台座11の円筒状支持部11aに形成された円弧溝11aa,11aaの一端の被係止穴11ao,11aoから抜け(図13参照)、係止が解除されることで、内側操作ハンドル15の回動が自由となるので、図2に示す室内側から視て、内側操作ハンドル15をロック解除位置Poからロック位置Pcに回動することができる。 When the cylindrical body portion 27 moves against the spring force of the compression coil spring 35, the locking pin 28 penetrating the cylindrical body portion 27 is formed with both ends 28e, 28e formed on the cylindrical support portion 11a of the inner pedestal 11. 13), the inner operating handle 15 is free to rotate, as shown in FIG. As viewed from the inside of the room, the inner operating handle 15 can be rotated from the unlocked position Po to the locked position Pc.

なお、トリガー操作部材21を操作して、係止ピン28を被係止穴11ao,11aoから抜いて係止を解除し、内側操作ハンドル15を僅かでも回動すると、トリガー操作部材21の揺動操作を終えても、係止ピン28の両端28e,28eは被係止穴11ao,11acを除く円弧溝11aa,11aaにあって円弧溝11aa,11aaに沿って係止ピン28は回動可能であり(図13参照)、したがって、円筒状部材12を介して内側操作ハンドル15も回動することができる。
外側操作ハンドル55も同様に作動する。
If the trigger operating member 21 is operated to release the locking pin 28 from the locked holes 11ao, 11ao and the inner operating handle 15 is rotated even slightly, the trigger operating member 21 will swing. Even after the operation is finished, both ends 28e, 28e of the locking pin 28 are in the arcuate grooves 11aa, 11aa excluding the locked holes 11ao, 11ac, and the locking pin 28 can be rotated along the arcuate grooves 11aa, 11aa. Yes (see FIG. 13), so that the inner operating handle 15 can also be rotated via the cylindrical member 12 .
The outer operating handle 55 operates similarly.

閉扉した状態で、内側操作ハンドル15をロック位置Pcに回動すると、回動基部16aから突設されるロックローラ18が、旋回して戸口枠5の方に突出し、戸口枠5の鉛直枠部5aのローラ受口19hに挿入し(図2に実線で示す)、扉8を閉じ側に押え、扉8の周辺突条部8pがクッション部材7に強く押圧されて、戸口4を気密に閉塞するロック状態とすることができる。 When the inside operation handle 15 is rotated to the lock position Pc with the door closed, the lock roller 18 protruding from the rotation base 16a rotates and protrudes toward the door frame 5 to move the vertical frame portion of the door frame 5. 5a (indicated by the solid line in FIG. 2), the door 8 is pressed to the closing side, and the peripheral ridges 8p of the door 8 are strongly pressed by the cushion member 7 to airtightly close the doorway 4. can be locked.

内側操作ハンドル15をロック位置Pcに回動すると、係止ピン28の両端28e,28eが被係止穴11ac,11acと回動位置が一致し、それまでにトリガー操作部材21の操作を終えていても、圧縮コイルばね35のばね力により係止ピン28が円柱体部27とともに軸方向の外側操作ハンドル55側に移動して被係止穴11ac,11acに係止することで、係止ピン28の回動が規制され、円筒状部材12を介して内側操作ハンドル15の回動が規制され、さらにはハンドル回動軸31および円筒状部材52を介して外側操作ハンドル55の回動が規制される(図8参照)。 When the inner operating handle 15 is rotated to the locking position Pc, the both ends 28e of the locking pin 28 are aligned with the locked holes 11ac, 11ac, and the trigger operating member 21 has been operated by then. However, due to the spring force of the compression coil spring 35, the locking pin 28 moves axially toward the outer operation handle 55 side together with the cylindrical body portion 27 and is locked in the locked holes 11ac, 11ac. 28 is restricted, rotation of the inner operating handle 15 is restricted via the cylindrical member 12, and further rotation of the outer operating handle 55 is restricted via the handle rotating shaft 31 and the cylindrical member 52. (See FIG. 8).

したがって、内側操作ハンドル15と外側操作ハンドル55は、ロック位置Pcに維持されて回動を規制されるので、ねじりコイルばね36が外側操作ハンドル55をロック解除位置Poに付勢していてもロック状態が維持される。 Therefore, since the inner operating handle 15 and the outer operating handle 55 are maintained at the locking position Pc and their rotation is restricted, even if the torsion coil spring 36 urges the outer operating handle 55 to the unlocking position Po, the lock is locked. state is maintained.

すなわち、衝撃や振動によりロックローラ18のローラ受口19hへの挿入によるロック状態が緩むことはなく、緩むことで、コイルばね36により内側操作ハンドル15および外側操作ハンドル55が回動してロックが解除されるようなことは防止される。
また、不用意に内側操作ハンドル15または外側操作ハンドル55を回動したりするのも防止することができる。
That is, the locked state by inserting the lock roller 18 into the roller socket 19h is not loosened by impact or vibration, and the loosening causes the coil spring 36 to rotate the inner operating handle 15 and the outer operating handle 55 to unlock. It is prevented from being canceled.
In addition, it is possible to prevent the inside operation handle 15 or the outside operation handle 55 from being turned carelessly.

閉扉時に、内側操作ハンドル15と外側操作ハンドル55がロック位置Pcにあって、ロックローラ18がローラ受口19hに挿入されてロック状態にあるときに、内側操作ハンドル15側のトリガー操作部材21または外側操作ハンドル55側のトリガー操作部材61が操作されると、スライドバー33が圧縮コイルばね35のばね力に抗して内側操作ハンドル15側に移動し、円柱体部27を貫通する係止ピン28が、内側台座11の円筒状支持部11aに形成された被係止穴11ac,11acから抜け(図13参照)、係止が解除されるので、内側操作ハンドル15と外側操作ハンドル55は回動が自由となり、図2に示す室内側から視て、ロック位置Pcからロック解除位置Poに回動することができ、ロック状態を解除して、扉8を開くことができる。 When the door is closed, the inner operating handle 15 and the outer operating handle 55 are at the locking position Pc, and the lock roller 18 is inserted into the roller socket 19h to lock the trigger operating member 21 or the trigger operating member 21 on the inner operating handle 15 side. When the trigger operating member 61 on the outer operating handle 55 side is operated, the slide bar 33 moves toward the inner operating handle 15 side against the spring force of the compression coil spring 35, and the locking pin that penetrates the cylindrical body portion 27 is opened. 28 slips out of the locked holes 11ac, 11ac formed in the cylindrical support portion 11a of the inner pedestal 11 (see FIG. 13). The door 8 can be freely moved and can be rotated from the locked position Pc to the unlocked position Po as viewed from the inside of the room shown in FIG.

図8および図11,図12を参照して、円筒状部材12とともに回動し、かつ回動中心軸Lcの軸方向に移動可能な係止ピン28が、内側操作ハンドル15および外側操作ハンドル55のロック位置Pcとロック解除位置Poの各位置で、圧縮コイルばね35の付勢力により移動して被係止穴11acまたは被係止穴11aoに係止することができ(図8参照)、内側操作ハンドル15と外側操作ハンドル55は回動が規制される。 8, 11 and 12, locking pin 28, which rotates together with cylindrical member 12 and is movable in the axial direction of rotation center axis Lc, is attached to inner operation handle 15 and outer operation handle 55. At each of the locking position Pc and the unlocking position Po, it can be moved by the urging force of the compression coil spring 35 and locked to the locked hole 11ac or the locked hole 11ao (see FIG. 8). Rotation of the operating handle 15 and the outer operating handle 55 is restricted.

そして、係止ピン28が被係止穴11acまたは被係止穴11aoに係止した状態で、トリガー操作部材21,61を操作すると、トリガー変換機構20,60を介してスライドバー33が係止ピン28と一体に圧縮コイルばね35の付勢力に抗して移動して係止ピン28の被係止穴11acまたは被係止穴11aoとの係止を解除して(図13参照)、内側操作ハンドル15および外側操作ハンドル55の回動を許可するので、圧縮コイルばね35をこのように利用することで、トリガー操作部材21,61は係止ピン28の被係止穴11acまたは被係止穴11aoとの係止を解除するときにのみ操作するので、簡単な構造で、トリガー操作部材21,61の操作性を向上させることができる。 When the trigger operating members 21 and 61 are operated while the locking pin 28 is locked in the locked hole 11ac or locked hole 11ao, the slide bar 33 is locked via the trigger conversion mechanisms 20 and 60. It moves integrally with the pin 28 against the urging force of the compression coil spring 35 to release the engagement of the locking pin 28 with the locked hole 11ac or the locked hole 11ao (see FIG. 13). Since the operating handle 15 and the outer operating handle 55 are allowed to rotate, by using the compression coil spring 35 in this manner, the trigger operating members 21 and 61 can be moved into the locked hole 11ac of the locking pin 28 or the locked hole 11ac. Since it is operated only when the engagement with the hole 11ao is released, the operability of the trigger operating members 21, 61 can be improved with a simple structure.

本ロックハンドル装置10は、図7および図8に示されるように、内側操作ハンドル15とハンドル回動軸31を介して一体に回動する外側操作ハンドル55をロック解除位置Poに向かう方向に回動付勢するねじりコイルばね36を備えるので、内側操作ハンドル15および外側操作ハンドル55がロック位置Pcとロック解除位置Poの間にあるときは、係止ピン28は両端28e,28eが内側台座11の円弧溝11aa,11aaにあって回動可能で、内側操作ハンドル15および外側操作ハンドル55は、ねじりコイルばね36の付勢力によりロック解除位置Po側に回動付勢されて、開扉時に、内側操作ハンドル15が自然とロック解除位置Poに回動して、ロック解除位置Poで係止ピン28が被係止穴11aoに係止して内側操作ハンドル15と外側操作ハンドル55は回動が規制されるので、ロックローラ18がロック受部19に係合できる位置に突出して戸口枠5に衝突するような事態は回避することができる。 As shown in FIGS. 7 and 8, the lock handle device 10 rotates the inner operating handle 15 and the outer operating handle 55, which are integrally rotated via the handle rotating shaft 31, toward the unlocking position Po. Since the torsion coil spring 36 for dynamically biasing is provided, when the inner operating handle 15 and the outer operating handle 55 are between the locking position Pc and the unlocking position Po, the locking pin 28 has both ends 28e, 28e attached to the inner pedestal 11. The inner operating handle 15 and the outer operating handle 55 are urged to rotate toward the unlocked position Po by the urging force of the torsion coil spring 36, and when the door is opened, The inner operating handle 15 is naturally rotated to the unlocking position Po, and the locking pin 28 is locked in the locked hole 11ao at the unlocking position Po, so that the inner operating handle 15 and the outer operating handle 55 are not rotated. Since it is regulated, it is possible to avoid a situation in which the lock roller 18 protrudes to a position where it can be engaged with the lock receiving portion 19 and collides with the doorway frame 5 .

図11ないし図13に示されるように、トリガー変換機構20,60は、トリガー操作部材21,61の操作による作動がリンク部材22,62を介してトリガー作動部材23,63を摺動し、同トリガー作動部材23,63の先端部のローラ24,64が延長部材25,65の円錐体部26,66の円錐面27t,67tを押圧することによりスライドバー33を圧縮コイルばね35の付勢力に抗して他方向に移動することで、簡単な構造でトリガー操作部材21,61の作動をスライドバー33の移動に変換して係止ピン28による係止を解除し、内側操作ハンドル15および外側操作ハンドル55の回動を許可することができる。 As shown in FIGS. 11 to 13, the trigger conversion mechanisms 20 and 60 are operated by operating the trigger operating members 21 and 61 to slide the trigger operating members 23 and 63 via the link members 22 and 62, respectively. The rollers 24, 64 at the tip of the trigger operating members 23, 63 press the conical surfaces 27t, 67t of the conical portions 26, 66 of the extension members 25, 65 so that the slide bar 33 is biased by the compression coil spring 35. By moving in the opposite direction, the operation of the trigger operating members 21, 61 is converted into the movement of the slide bar 33 with a simple structure to release the locking by the locking pin 28, and the inner operating handle 15 and the outer Rotation of the operating handle 55 can be permitted.

図8を参照して、一方の延長部材25が有する円筒状部材12に摺動可能に嵌合する円柱体部27を中心軸に直交して貫通するピン状の係止ピン28は、円柱体部27より突出した端部が円筒状部材12の軸方向に長い長孔12eに軸方向に摺動可能に嵌合して貫通し同円筒状部材12とともに回動し、かつ係止ピン28の円筒状部材12の長孔12eに嵌合し貫通した端部28e,28eは、内側操作ハンドル15および外側操作ハンドル55がロック位置Pcとロック解除位置Poの各位置にあるときに、被係止穴11ac,11aoに係止可能であるので、円筒状部材12とともに回動し、かつ軸方向に相対移動可能な係止ピン28は、内側操作ハンドル15および外側操作ハンドル55がロック位置Pcとロック解除位置Poの各位置で、圧縮コイルばね35の付勢力により移動して被係止穴11ac,11aoに係止することができる。 Referring to FIG. 8, a pin-like locking pin 28 passing perpendicularly to the central axis through a cylindrical body portion 27 slidably fitted to the cylindrical member 12 of one extension member 25 is a cylindrical body. The end protruding from the portion 27 is axially slidably fitted into and penetrates an elongated hole 12e of the cylindrical member 12, and rotates together with the cylindrical member 12. The end portions 28e, 28e, which are fitted and penetrated through the long hole 12e of the cylindrical member 12, are locked when the inner operating handle 15 and the outer operating handle 55 are at the locking position Pc and the unlocking position Po. Since it can be locked in the holes 11ac and 11ao, the locking pin 28, which rotates together with the cylindrical member 12 and is relatively movable in the axial direction, allows the inner operating handle 15 and the outer operating handle 55 to be locked at the lock position Pc. At each position of the release position Po, it can be moved by the urging force of the compression coil spring 35 and locked to the locked holes 11ac and 11ao.

そして、係止ピン28が被係止穴11ac,11aoに係止した状態で、トリガー操作部材21,61を操作すると、トリガー変換機構20,60を介してスライドバー33が係止ピン28と一体に圧縮コイルばね35の付勢力に抗して移動して係止ピン28の被係止穴11acまたは被係止穴11aoとの係止を解除して、内側操作ハンドル15および外側操作ハンドル55の回動を許可することができる。 When the trigger operating members 21 and 61 are operated while the locking pins 28 are locked in the locked holes 11ac and 11ao, the slide bar 33 is integrated with the locking pins 28 via the trigger conversion mechanisms 20 and 60. Then, the locking pin 28 is disengaged from the locking hole 11ac or the locking hole 11ao by moving against the biasing force of the compression coil spring 35, and the inner operating handle 15 and the outer operating handle 55 are disengaged. Rotation can be allowed.

図9および図10を参照して、トリガー操作部材21,61の揺動がリンク部材22,62を介してトリガー作動部材23,63を回動中心軸Lcに直交する方向に移動するので、操作ハンドル15,55を掴みながら、トリガー操作部材21,61を握ることで、トリガー操作部材21,61を揺動操作することができ、トリガー操作部材21,61の操作がし易く、使い勝手が良い。 9 and 10, the rocking motion of the trigger operating members 21, 61 moves the trigger operating members 23, 63 through the link members 22, 62 in the direction perpendicular to the rotation center axis Lc. By gripping the trigger operating members 21 and 61 while gripping the handles 15 and 55, the trigger operating members 21 and 61 can be swung, and the trigger operating members 21 and 61 are easy to operate and convenient to use.

図8および図11,図12を参照して、トリガー作動部材23,63の先端部にはローラ24,64が取り付けられ、同ローラ24,64が延長部材25,65の円錐体部26,66の円錐面26t,66tに接して転動しながら押圧するので、トリガー変換機構20,60が円滑に作動し、トリガー操作部材21,61の操作を容易にする。 8, 11 and 12, rollers 24, 64 are attached to the distal ends of the trigger operating members 23, 63, and the rollers 24, 64 extend from the conical portions 26, 66 of the extension members 25, 65. Since the conical surfaces 26t, 66t are pressed while rolling in contact therewith, the trigger conversion mechanisms 20, 60 operate smoothly and the trigger operation members 21, 61 can be easily operated.

以上、本発明に係る一実施の形態に係るロックハンドル装置について説明したが、本発明の態様は、上記実施の形態に限定されず、本発明の要旨の範囲で、多様な態様で実施されるものを含むものである。 Although the lock handle device according to one embodiment of the present invention has been described above, aspects of the present invention are not limited to the above-described embodiment, and can be implemented in various aspects within the scope of the gist of the present invention. includes things.

例えば、本実施の形態では、ロックローラ18は内側操作ハンドル15の回動基部16aに突設されていたが、外側操作ハンドル55の回動基部56aに突設されるようにしてもよい。 For example, in the present embodiment, the lock roller 18 protrudes from the rotation base 16a of the inner operating handle 15, but may be protruded from the rotation base 56a of the outer operating handle 55.
