When car door 4 is set up in parallel the position when the door staggered positions is shifted from door, blade 9 with engage roller 10 engagings before, cam roller 17 contacts with lobe plate 18.After this, when car door 4 when the door staggered positions is shifted, cam roller 17 is pushed by lobe plate 18, simultaneously top pivot link 15 rotates, blade 9 with engage roller 10 and engage.Thus, action movie 12 is displaced to going-back position.
When car door 4 from the door staggered positions when door is set up in parallel displacement because the deadweight of action movie 12, cam roller 17 contacts with lobe plate 18, while top pivot link 15 rotates to stop part 20 sides.Then, when top pivot link 15 and stop part 20 butts, top pivot link 15 stops operating, and action movie 12 remains on the extrusion position.Afterwards, cam roller 17 leaves from lobe plate 18, and car door 4 is displaced to door and is set up in parallel the position.
Be provided with microswitch (position detecting device) 19 on car door 4, this microswitch 19 is used to detect action movie 12 and whether has been displaced to extrusion position.In this example, whether microswitch 19 by has carried out contacting with bottom pivot link 16 and detects action movie 12 and whether be displaced to extrusion position.In addition, in the gangway 1 be provided with detect the inlet the 1 full cut-off detecting sensor (not shown) of whether closing fully.
Be sent to the control setup of control elevator running from the information of full cut-off detecting sensor and microswitch 19.Control setup is according to control the elevator running from the information of full cut-off detecting sensor and microswitch 19.That is, control setup is only closed gangway 1 and action movie 12 when being positioned at extrusion position fully at elevator door, and the running of elevator is controlled to be car can move.In addition, be that control setup makes elevator door move to the direction of opening the door when departing from extrusion position before car begins to move in the position that elevator door cuts out gangway 1 and action movie 12 fully.In addition, be that control setup makes car stop to move when departing from extrusion position after car begins to move in the position that elevator door cuts out gangway 1 and action movie 12 fully.
Fig. 5 is the speed of the elevator door of state from the full-gear to the full-shut position of the gangway 1 in the presentation graphs 1 and the diagram of curves of time relation.As shown in the figure, gangway 1 from the full-gear to the full-shut position during in, the speed of elevator door rises in the raising speed interval, and constant in the constant speed interval, reduces in then between deceleration area.
In the raising speed interval, the speed of elevator door is rising behind 0 mild the rising significantly.In between deceleration area, the speed of elevator door reduces significantly in the speed from the constant speed interval that the back is mild to reduce, and 1 full-shut position becomes 0 in the gangway.In addition, between deceleration area in, speed is low-speed range smaller or equal to the scope of the speed that switches to the elevator door of velocity variations when mild from velocity variations when big.In this example, low-speed range is the following scope of 20mm/s.When the speed of elevator door was in the low-speed range, each stop door 7 was closed gangway 1 fully, and car door 4 can be with respect to 7 displacements of stop door.
Next explanation action.Fig. 6 A be between the deceleration area that is illustrated among Fig. 5 in, the birds-eye view of the door gear of the elevator of (at the state of moment t1) when the speed of elevator door reduces significantly.In addition, Fig. 6 B be between the deceleration area that is illustrated among Fig. 5 in, the birds-eye view of the door gear of the elevator of (at the state of moment t2) when the speed of elevator door reduces gently.And, Fig. 6 C be between the deceleration area that is illustrated among Fig. 5 in, the speed of elevator door becomes at the 0 o'clock birds-eye view of door gear of elevator of (at the state of moment t3).
When car door 4 by means of the propulsive effort of door drive from the gangway 1 state of opening fully when the direction of closing the door moves, stop door 7 with also move when car door 4 engages to the direction of closing the door.
When for example reducing significantly in the speed of elevator door is between deceleration area, as shown in Figure 6A, car door 4 is displaced to a staggered positions, blade 9 with engage roller 10 engagings.At this moment, cam roller 17 keeps by the state that is pressed on the lobe plate 18, and action movie 12 remains on going-back position.
When the speed of elevator door be in the low-speed range, when each stop door 7 is closed gangway 1 fully, shown in Fig. 6 B, stop door 7 stops to move to the direction of closing the door, and has only car door 4 to continue by means of the propulsive effort of door drive to moving of the direction of closing the door.That is, car door 4 is set up in parallel displacement from the door staggered positions towards door with respect to stop door 7.At this moment, blade 9 is removed with the engaging that engages roller 10.In addition, with when lobe plate 18 contacts, top pivot link 15 rotates at cam roller 17, and action movie 12 is shifted towards extrusion position from going-back position.
Then, when car door 4 continues when the direction of closing the door moves, top pivot link 15 and stop part 20 butts, top pivot link 15 stops operating.Afterwards, car door 4 continues to move to the direction of closing the door, and cam roller 17 leaves from lobe plate 18.Then, car door 4 arrives door and is set up in parallel the position, and gangway 1 is closed (Fig. 6 C) fully by elevator door.
Under the 1 complete closing state of gangway, bottom pivot link 16 contacts with microswitch 19, has arrived extrusion position thereby detect action movie 12.
After this, when having been confirmed that by control setup complete closing movement that action movie 12 has been displaced to extrusion position and gangway 1 has been finished, car can move.
Open the door when action at elevator door, by with above-mentioned opposite action, car door 4 engages with stop door 7, action movie 12 is from the extrusion position position of drawing back that is shifted.
Action when next illustrative examples is clipped between the elevator door as foreign matters such as ropes.When elevator door cut out gangway 1 fully, if accompany foreign matter between elevator door, then foreign matter can hinder action movie 12 to be shifted to extrusion position.Thus, microswitch 19 is failure to actuate, and control setup detects action movie 12 and departed from extrusion position.The elevator door action of opening the door thus.
Accompanying between each elevator door under the situation that begins to move under the state of foreign matter even work as car, because car is mobile, foreign matter is applied in tension force, and action movie 12 departs from extrusion position thus.Like this, bottom pivot link 16 leaves microswitch 19, and control setup detects action movie 12 and departed from extrusion position.Thereby car stops to move.
In the door gear of such elevator, when stop door 7 is closed gangway 1 fully, car door 4 is set up in parallel between position and the door staggered positions at door and is shifted, car door 4 be positioned at door when being set up in parallel the position action movie 12 be displaced to extrusion position, action movie 12 is displaced to going-back position when car door 4 is positioned at staggered positions, so action movie 12 is contained between car door 4 and the stop door 7 usually, only before elevator door will soon cut out gangway 1 fully, make action movie 12 outstanding from the side end of closing the door of elevator door.Can prevent that thus hand barrow etc. from bumping with action movie 12, can reduce the intensity of action movie 12 and make action movie 12 lightweights.Therefore, even for example light weight such as rope and crooked easily foreign matter also can detect foreign matter more reliably by simple structure.
In addition, make the shift assembly 21 of action movie 12 displacements have top pivot link 15 and the lobe plate 18 that is located on the stop door 7, corresponding to the displacement of car door 4 with respect to stop door 7, this top pivot link 15 is pushed by lobe plate 18 and is rotated with respect to car door 4 simultaneously, so can make action movie 12 with respect to the displacement interlock with respect to stop door 7 of the displacement of elevator door and car door 4 by simple structure.
In addition, whether be displaced to extrusion position owing to detect action movie 12 by microswitch 19, and according to control the running of elevator from the information of microswitch 19, so can suppress the generation of the misoperation of elevator door.
In addition, the position of closing gangway 1 and active gage 12 at elevator door fully is when departing from extrusion position before car begins to move, control setup makes elevator door move to the direction of opening the door, so to be clipped in by the state between stop and the car under the situation between the elevator door, can prevent that car from beginning to move at easy crooked foreign matters such as for example ropes.
In addition, because closing the position of gangway 1 and action movie 12 fully when elevator door is when departing from extrusion position after car begins to move, control setup makes car stop to move, even so the car foreign matter easily crooked with for example rope etc. by stop and car between the state situation that begins to move under, by the displacement of action movie 12, also can car be stopped.
In addition, the overhang C at the active gage 12 of action movie 12 during at extrusion position regulates in the length of the part between top turning cylinder 13 and the pin 15a and the length of the part of top pivot link 15 between top turning cylinder 13 and cam roller 17 by regulating top pivot link 15.
