In the locking device of patent document 1, while fixing bolt and lock bolt are driven and carry out unlocking operation.
Therefore, when retreating fixing bolt and lock bolt to be converted to unlocking condition to Men Nei, because pressing on the door bolt of doorframe
The peripheral wall of eye (striker) and any one or the two in fixing bolt or lock bolt generate back pressure.Fixing bolt or lock bolt and door bolt eye
Resistance to sliding between periphery increases because of back pressure.The case where fixing bolt connects under locked state with door bolt intraocular pressure is self-evident, i.e.,
Make in the case where lock bolt first contacts door bolt eye, after lock bolt is detached from from door bolt eye, fixing bolt is also crimped with the periphery of door bolt eye.Cause
This generates resistance to sliding in the entire stroke until fixing bolt is detached from from door bolt eye.As a result, being difficult to carry out unlocking behaviour
Make.Especially in the case where carrying out unlocking operation using actuators such as motors, it is possible to produce movement is bad.
In addition, may be also constructed to individually operate lock bolt from outside in the locking device of patent document 1.So
And in the locking device of patent document 1, the protrusion movement by lock bolt under unlocking condition relative to trigger member is set as converting to locking
Condition, therefore in the case where that only lock bolt can be made freely to be acted, in the state of being unlocked and open door,
Only trigger member is pressed into accidentally and lock bolt is made to be formed as the state protruded relative to trigger member.As a result, fixing bolt protrudes, because
This ease of use is poor.
In addition, in the locking device of patent document 1, if being configured to individually operate lock bolt from outside,
Under shutdown state without opening door operation but carry out lock bolt and retreat, protrude operation, thus fixing bolt is again converted to lock
State and opening door operation can not be carried out, ease of use is very poor.

It limits and is retained in lockset position of coupler.
Then, if carrying out shutdown movement, latch bolt 6 and trigger member 7 are interfered with doorframe 1, such as Fig. 5, Fig. 6 (b)
It is shown, it is moved to retracted position, clutch-plate 10 rearward moves in the state of keeping the posture of initial position.Due to clutch
The movement of piece 10, top (the contact path for being pressed piece 13 for pressing portion 9 and being moved to fixed stop 3 of the clutch-plate 10
Starting point).
Then, if shutdown movement finishes, the lock bolt of latch bolt 6 and doorframe 1 fastens 5 face of eye, therefore only latch bolt 6 with a bolt or latch
It is moved to salient position.As shown in Fig. 7 (a), Fig. 8 (a), since the independent protrusion of latch bolt 6 acts, the follower of clutch-plate 10
11 rotate and rise on the movement protrusion 12 of trigger member 7.
It is pressed downwards by the rotation of clutch-plate 10 and is pressed piece 13, thus fixed stop 3 moves downwards, will
The locking of itself and the locking stepped part 23b of bar driving sliding part 23 release.As a result, utilizing pressure as shown in Fig. 7 (b), Fig. 8 (b)
The pretightning force of contracting spring 23a moves bar driving sliding part 23 rearward, the fixed rotation of drive rod 19 to locking rotation position, Gu
Determine bolt 4 and is moved to locked position.
For the movement protrusion 12 of trigger member 7, pass through as shown in Fig. 8 (a) clutch-plate 10 press the realization of portion 9
After the locking releasing movement of fixed stop 3 terminates, as shown in Fig. 8 (b), even if being completely converted into convex shape in latch bolt 6
In the state of state, which extends forwards also for the rotation attitude for keeping clutch-plate, also, in order to fix
The front-end edge for being pressed piece 13 of retainer 3 is set in the close of the front-rear direction position for pressing portion 9 when latch bolt 6 protrudes completely
Preceding place in the state that latch bolt 6 protrudes completely, presses the prolonging relative to the back side for being pressed piece 13 of portion 9 as shown in Fig. 8 (b)
Long line (R13) is located below and (contacts the terminal in path, the starting point of break path).
The unlocking operation after locked state more than being carried out and acting fixed drive rod 19 from portion outdoors.
If carrying out rotation process to fixed drive rod 19, bar drives sliding part 23 mobile forwards (right side in Fig. 8 (b)), Gu
Retainer 3 is determined after temporarily moving downwards using the pretightning force of locking stepped part 23b resistance torsional spring 25, with locking ladder

The position of side, therefore even if trigger member 7 is only made retreat mobile and become latch bolt 6 relative to trigger member 7 in this state
The state relatively protruded will not carry out automatic locking movement.
Also, as shown in Figure 11 (a), in doorframe 1 in the presence of concave-convex equal and the trigger member 7 in shutdown movement the amount of retreating ratio
In the case that the amount of retreating of latch bolt 6 is bigger, rotation driving slightly is carried out to clutch-plate 10, chooses spy by accident in difference (δ)
In the case where definite value, portion 9 is pressed sometimes and is pressed piece 13 and is in identical height.
If both latch bolt 6 and trigger member 7 are mobile to direction is retreated in this state, such as shown in Figure 11 (b), pressure
It dynamic portion 9 and is pressed piece 13 and is possible to interfere with each other and can not carry out the shutoff operation of door, in order to eliminate the phenomenon, by guide portion
15 are set to latch bolt 6 and clutch-plate 10.
That is, as shown in Figure 11 (b), in the case where the interference for producing the portion of pressing 9 and being pressed between piece 13, if from
Portion carries out latch bolt 6 and retreats operation outdoors, then latch bolt 6 resists pressure relative to irremovable because of interference lock bolt shell 14
The reaction force of contracting spring 28 and it is mobile to direction is retreated, in the near future, as shown in Figure 11 (c), the guide portion 15 of latch bolt 6 and
The guide portion 15 of clutch-plate 10 abuts.
If further carrying out retreating operation to latch bolt 6 from the state, clutch-plate 10 exists around rotation center (C10)
It is deasil rotated in Figure 11 (c), therefore disturbance state is released from and is able to carry out door-closing operation.In addition, in this case, being
It so that clutch-plate 10 is carried out clockwise rotation, lead-in chamfered 33 can also be set to the portion of pressing 9 and be pressed
Both pieces 13.
Also, the zeroing mechanism of automatic locking movement in this example, is assembled in locking device.Utilize 34 (reference of mounting plate
Zeroing mechanism Fig. 4) is fixed on to shell 16 in a manner of being able to carry out rotation process, the zeroing mechanism is by making rotation process portion
The cancellation operating member 35 that 35a exposes from foreboard 17 and configured forms (referring to Fig.1, Fig. 4).
If carrying out rotation process to operating member 35 is cancelled, cancels retainer 35b (referring to Fig.1) and be locked to bar driving
Sliding part 23, hereafter, the engaging with relative to fixed stop 3, which is detached from, is independently held in unlocking pair for bar driving sliding part 23
Position is answered, therefore automatic locking movement will not be generated.
In addition, latch bolt 6 illustrated above has lock bolt block portion 6a in front end and the rod-shaped feelings being integrated is integrally formed
Condition, however, it is not limited to this, for example, lock bolt block portion 6a may be also constructed to the so-called reversible type lock bolt that can be rotated horizontally.
According to embodiment, locking device includes fixing bolt 4, is fastened with a bolt or latch the locking that eye 2 engages to the fixing bolt of doorframe 1
Locality pre-tightens, and is engaged by unlocking operation to fixed stop 3, is held in lockset position of coupler；Latch bolt 6,
Elasticity is locked to the lock bolt door bolt eye 5 of doorframe 1 under shutdown state, can carry out retreating operation from portion outdoors, is fastening eye 5 with a bolt or latch with lock bolt
Ensure mobile space appropriate between the advance and retreat path of fixing bolt 4 and fixing bolt door bolt eye 2 under locking state；Trigger member 7,
It is crimped under shutdown state with doorframe 1 and is held in retracted position；And retainer driving portion 8, pass through latch bolt 6 and triggering
It is mobile while part 7 is from salient position to retracted position, by latch bolt 6 relative to trigger member 7 opposite protrusion displacement as solid
Determine retainer 3 to release displacement relative to the locking of fixing bolt 4 and transmitted, releases driving in the locking to fixed stop 3
Later, until latch bolt 6 and trigger member 7 again while retreat movement until, will be because latch bolt 6 be relative to trigger member 7
The transmission lifting of the operating force of fixed stop 3 caused by relative displacement.
In the locking device of embodiment, in the state that door is opened, it is locked to by the fixing bolt 4 pre-tightened to locking direction
Fixed stop 3 and be held in lockset position of coupler, protruding state is remained by the latch bolt 6 and trigger member 7 that pre-tighten to protrusion direction.
If closed door from the state, latch bolt 6 and trigger member 7 abut with doorframe 1 and are moved to retreat simultaneously
Position, if door is moved to so that the degree that latch bolt 6 is aligned with the lock bolt of doorframe 1 door bolt eye 5, only latch bolt 6 are moved to
Salient position and enter lock bolt fasten with a bolt or latch eye 5.
Retainer driving portion 8 is linked to, can be by latch bolt 6 and trigger member 7 from salient position simultaneously to retreating
Position is mobile and the opposite protrusion displacement by latch bolt 6 relative to trigger member 7 is used as in fixed stop 3 relative to fixing bolt 4
Locking release used in be displaced and export.Hereafter, it is displaced relative to trigger member 7 to protrusion direction in latch bolt 6
In the case of, that is, if shutdown movement finishes, latch bolt 6 enters lock bolt and fastens eye 5 with a bolt or latch, by relative displacement by fixed stop
3, which release direction to the locking relative to fixing bolt 4, is driven, and makes the locking solution relative to fixed stop 3 using pretightning force
Fixing bolt 4 after removing is moved to locked position and carries out automatic locking.
If automatic locking finish, until latch bolt 6 and trigger member 7 again while retreat movement until, by because
Hereafter the transmission lifting of the operating force of fixed stop 3 caused by relative displacement of the latch bolt 6 relative to trigger member 7 is making
After fixing bolt 4 is converted to unlocking condition, even if individually being operated to latch bolt 6, it will not implement automatic locking.
Because latch bolt 6 caused by mobile while latch bolt 6 and trigger member 7 are from salient position to retracted position relative to
Output of the opposite protrusion displacement of trigger member 7 to fixed stop 3, can be by single suitably with connection when the two is retreated
Latch bolt 6 and fixed stop 3 are linked and are realized by member, and the connection after fixed stop 3 is acted releases, can be by making
At the relative position of latch bolt 6 and trigger member 7 of the lifting unit of above-mentioned connection unit when fixed stop 3 is acted into
Action is made and is realized.
Therefore, when making fixing bolt 4 be converted to locked state by automatic locking movement, latch bolt 6 is protruded and is locked to
Lock bolt fastens eye 5 with a bolt or latch, in this state, between the advance and retreat path of fixing bolt 4 and fixing bolt fasten with a bolt or latch and ensure movement appropriate between eye 2
Gap.
Also, retainer driving portion 8 is configured to that retainer 3 is fixed relative to fixation using the displacement of latch bolt 6
The locking releasing of bolt 4 acts, and can be operated to fixing bolt 4 without impacting to latch bolt 6, therefore can utilize
Latch bolt 6 makes fixing bolt 4 be moved to lockset position of coupler in the state of ensuring mobile space between fixing bolt door bolt eye 2.
As a result, it is possible to drive the fixing bolt 4 to lockset position of coupler without applying back pressure to fixing bolt 4, therefore operate
Property improve.
In addition, 8 pairs of retainer driving portion because for the latch bolt after converting to unlocking condition after locking movement finishes
Automatic locking movement caused by 6 operation is limited.
As a result, will not be generated automatic locking dynamic even if retreating the trigger member 7 for the door opened under unlocking condition accidentally
Make, also, latch bolt 6 is operated from portion outdoors in the state of even if closing the door under unlocking condition, will not carry out automatic
Locking, therefore can be carried out the movement of user's imagination, user will not be caused to perplex.
According to embodiment, retainer driving portion 8 has clutch-plate 10, and the clutch-plate 10 is by latch bolt 6 relative to triggering
The opposite protrusion displacement of part 7 as the portion that presses 9 displacement and export, clutch-plate 10 presses portion 9 on contact path and breaks
It is moved on open circuit diameter, wherein on the contact path, to initiate from the contracting of the state of both trigger member 7 and latch bolt 6 protrusion
Position when finishing is moved back as starting point, the operating point of fixed stop 3 is located in the actuating range for pressing portion 9, so that
