Work pin can be made to return always in the state that the pin 59 that works does not engage with working component 42 by this composition
To correct position.
In the above-described configuration, when car door 25 is in the position for closing an end, the working component of 25 side of car door shown in Fig. 3
42 as indicated with broken lines in fig. 4, is engaged by its flat part 42a with the work pin 59 of 41 side of driving mechanism, driving mechanism 41 is supported
The spring force of anti-working spring 56 and the state for being maintained as Fig. 5.Thus, blocking member 35 and the support for supporting the blocking member 35
Frame 51 as can be seen from figures 8 and 9, the retreating position positioned at the lower part of cage side threshold 31.
If 4 leveling of carriage rests against stop, car door 25 starts door opening action.Start in the work that starts of the car door 25
Afterwards, during one section, work pin 59 engages with flat part 42a, when engaging continues and the length X of flat part 42a is comparable
It is long.Later, if car door 25 is mobile to defined open position, the solid line institute of work pin 59 such as Fig. 4 of driving mechanism 41 is constituted
Show, leaves from the flat part 42a of working component 42, engage with rake 42b.
That is, driving mechanism 41 is moved to defined open position from Men Duan is closed by car door 25, work pin 59 and car door
The clamping force of the working component 42 of side is released from, and by the reaction force of working spring 56, by bracket 51 and its is supported stifled
Plug member 35 is sent out from the state of Fig. 5 to the state of Fig. 6.Therefore, blocking member 35 is from Fig. 8, retreating position shown in Fig. 9 to figure
Show left sliding movement, reaches blocking position shown in Fig. 7.Then, the front end (diagram left part) of the blocking member 35 with
The diagram right side of stop side door sill 32 abuts, and the gap between threshold 31,32 is blocked.
Here, being opened in the case where having carried out the behavior for deliberately pushing door open in car travel if it is by door
With its linkedly blocking member immediately protrude if, then it is contemplated that due in traveling in, blocking member meeting outstanding
With the component contact of stop side and it is damaged.
But in embodiments of the present invention, even if door is to start work, blocking member will not be immediately to blocking position
It is prominent, but it is just prominent to blocking position to reach preset defined open position by door, therefore passes through car travel
In opening door operation, can also obtain carriage emergency stop stop until time, can prevent blocking member outstanding from flanking with stop
Touching and it is damaged.
In general, being provided in lift appliance and detecting the feelings in the case where deliberately opening door in the traveling of carriage
The door switch of condition stops carriage emergency stop by the disconnection movement of the door switch.As described above, in embodiments of the present invention
In, even if door carries out starting work, blocking member will not be prominent to blocking position immediately, reaches preset rule by door
Fixed open position is just prominent to blocking position, and therefore, during this period, carriage emergency stop is stopped.That is, prominent to blocking position after a stop
Out, therefore, the state of affairs of the component contact of blocking member and stop outstanding and breakage will not be generated.
Thus, so that blocking member, which carries out prominent movement, door defined open position, to be become corresponding to and detects sedan-chair
Compartment traveling in enabling and carriage emergency stop stop until the corresponding open position from the distance for closing Men Duanqi of opening time side
Formula sets the length X of flat part 42a shown in Fig. 4.
Here, interval, the i.e. gap size in the gap between threshold 31,32 is not certain value as described above, because of each layer
Installation error and it is different.In addition, also because the front and back of car guiding device loosen, boarding when carriage downward shift due to size produce
It changes dynamic.
In embodiments, it is configured to, blocking member 35 is installed on bracket 51 via leaf spring 52, can be moved along sliding
The swing in direction.That is, blocking member 35 being capable of the swing at the position (blocking position) after protrusion.In addition, by plate
Spring 52 is pushed to stop side (diagram left), is become if by car direction (diagram right) if retracting if pressing, pressing force solution
Except the construction for then returning to original blocking position.
Through this construction, can be configured to, running clearance than it is usually narrow in the case where, by cage side, (diagram is right
Side) it pushes back, it is prominent to blocking position in wider situation, the higher blocked state of closed stratum can be obtained.
In this way, the gap between threshold 31,32 is blocked, therefore, small articles will not when blocking member 35 is located at blocking position
It drops in well, can easily recycle from the gap.In addition, upper table of the upper surface of blocking member 35 than threshold 31,32
On the lower, therefore, the load of the object on threshold 31,32 will not be applied directly to blocking member 35 in face, can prevent because
It is applied the damage of the support portion of blocking member 35 caused by load.
Under the blocked state in the blocking member 35 blocking gap, if the load of carriage 4 significantly changes, carriage sometimes
4 temporarily can slightly rise.Even if the temporary rising of such carriage 4 is produced, also due to the upper corner of blocking member 35
It is carried out chamfering 35b, and blocking member 35 is supported by leaf spring 52, without generating the problems such as damaging.
Such as whens the case where in carriage 4 with the passenger that full state is taken disposably walking out carriage etc., carriage 4 can be temporary
Slightly rise.At this point, the blocking member 35 shown in fig. 6 positioned at blocking position also rises, sometimes with stop side door sill 32
Lower part side portion abuts against.But due to the upper corners of the blocking member 35 opposed with the lower part side portion of stop side door sill 32
Portion has been carried out chamfering 35b, therefore the abutting force of the part is weakened, and can prevent because of damage caused by abutting.In addition, blocking
Component 35 is supported by leaf spring 52, and therefore, in above-mentioned abutting, leaf spring 52 is also bent in the up-down direction, therefore is buffered by it
Declines accordingly can also be prevented because impacting caused by abutting because of damage caused by abutting.
On the other hand, if car door 25 carries out closing movement, the midway for closing an end position is reached in door, constitutes driving mechanism
41 work pin 59 such as Fig. 4's is shown in solid, engages with the rake 42b of working component 42.Then, with door face board 25a
The movement (closing the movement in direction) to diagram left, keep work pin 59 mobile to diagram top, make bar component 58 and and its
The pivotal support axis 45 of one is rotated clockwise to diagram.By the rotation, with the connecting rod 46 of 45 one of pivotal support axis and
It is rotated clockwise via the reaction force that other connecting rods 47,48,49 that bracket 51 links also resist working spring 56 to diagram.
It is returned as shown in Fig. 5 that is, driving mechanism 41 is engaged by work pin 59 with the rake 42b of working component 42
State, bracket 51 and moved at an upper portion thereof via the blocking member 35 that leaf spring 52 supports to Fig. 8 and retreating position shown in Fig. 9
It is dynamic.The movement knot at the time of clamped position for the pin 59 that works is changed into flat part 42a from the rake 42b of working component 42
Beam, after, until an end position is closed in the arrival of car door 25, keep the state.
In this way, when closing of car door 25, engaged with the working component 42 of car door side to closing a mobile midway at end,
By car door 25 mobile power and so that the blocking member 35 positioned at blocking position is slidably moved to retreating position.
The sliding of blocking member 35 is mobile by limiter 61, and blocking member 35 can be made correctly to stop at blocking position
With the both sides of retreating position.Thus, it is possible to be reliably prevented blocking member 35 do not stop at correct position and run it is excessive and its
He collides and generates damage component.In addition, even if assume produce operation it is excessive, also due to blocking member 35 is by leaf spring 52
Support, therefore, impact caused by capable of being buffered because of the collision with other component by the flexure of leaf spring 52 can prevent from reaching component
The degree of damage.
In addition, gap is generated in the holding section engaged with bracket 51 sometimes in the case where leaf spring 52 has been bent, if
The gap, which sandwiches dust etc., can not then recover to original shape.It is therefore preferable that being possible to that the part in the gap can be generated
Implement the protection such as setting for being filled or covering in advance.
In addition, leaf spring 52 has the function of flexure vertically as described above.Thus, in order to more effectively generate
