In the lift appliance 1, the stop 11 set by each floor in building is provided with and the sedan-chair in elevating road 3 The gateway 12 that railway carriage or compartment 4 is connected, stop door 2 is provided with the gateway 12.When car 4 is flat bed, stop door 2 is with being arranged at The side of car door 25 of the gateway 24 of car 4, engages, the opening and closing with car door 25 is mutually interlocked via mutual interlocking gear (not shown) Action is opened and closed in ground.

Fig. 2 is that the car door 25 for the gateway that car 4 is arranged at from coming from the side of stop 11 is (fully closed in an end position is closed Position) situation stereogram.Car door 25 is to make 2 door face boards 25a, 25b (diagram for eliminating surface plate of door) to mutual Different diagram right and lefts carries out starting work, so-called split mode.These 2 door face boards 25a, 25b are by door open/close machine To diagram left and right directions driving, action is opened and closed.

In addition, door open/close machine is known, due to not having direct relation with the application utility model, therefore structure is omitted Explanation is made, by the power of motor (not shown), 2 door face boards 25a, 25b is mutually interlocked, is driven in the lateral direction along guide rail It is dynamic, action is opened and closed.

In the passageway part of the car 4, cage side threshold 31 is provided with, by 2 doors of above-mentioned composition car door 25 Panel 25a, 25b, are opened and closed direction along it and are guided in the way of it can slide.The cage side threshold 31 is arranged at car The lower edge of gateway 24, the guiding groove formed in its upper surface engages respectively with 2 door face boards 25a, 25b bottom, will 2 door face boards 25a, the 25b are guided along opening and closing direction.

Relative to the cage side threshold 31, threshold 32 is also provided with as shown in Figure 3 in the side of stop 11.The stop side door Sill 32 are with keeping predetermined distance arranged opposite with the one side (Fig. 3 left surface) of cage side threshold 31.In the stop side door sill 32 upper surface is also formed with guiding groove, and stop door 2 shown in Fig. 1 is opened and closed into direction along it is carried out in the way of it can slide Guiding.

The stop side door 2 although not shown but be also the split mode with 2 door face boards, therefore, if as described above, car 4 flat beds rest against stop 11, then the stop side door 2 engages with the car door 25, and action is opened and closed together with car door 25. That is, stop door 2 is when car 4 is not flat bed, and 2 door face boards are locked in closed state by mutual interlocking gear (not shown), When car 4 is flat bed, stop door 2 is engaged and above-mentioned lock-out state quilt with the fastened component (not shown) of the side of car 4 Release, action is opened and closed together with car door 25.

When the flat bed of car 4 rests against specified layer, as described above, being produced between cage side threshold 31 and stop side door sill 32 Gap shown in raw Fig. 3.In embodiment of the present utility model, set in order to which the gap is blocked as illustrated Blocking member 35.

As shown in Fig. 2 the blocking member 35 is split by left and right.The partitioning portion is the cage side threshold when car 4 is lifted 31 interlock (i.e. from that with being arranged at the mutual interlocking gear (not shown) (the roller part specifically engaged with cage side) of stop side This side pass through) part, in order to allow mutual interlocking gear by and left and right keep compartment of terrain be divided.That is, even if contingency exists Car is lifted in the state of blocking member is sent to blocking position, and the mutual interlocking gear of stop side also can be from being sent Blocking member 35 partitioning portion formation space pass through, therefore, the blocking member being sent is to send out with mutual interlocking gear Raw collision.

In stop side door sill 32, it is provided with cage side threshold 31 to configuration state into the space segment of the segmentation Protrude and swim embedding module component (not shown).The module component be integrally provided to stop side door sill 32, with cage side threshold 31 Opposed and opposed with the divided space segment of blocking member 35 opposed portion.Therefore, if car 4 is flat bed, stop side door Sill 32 are opposed with cage side threshold 31, then the module component set in stop side door sill 32 turns into dashes forward into divided space segment Go out and swim embedding state.Thus, the space produced in partitioning portion turns into substantially to be blocked with swimming the module component being embedded in inside it State, be prevented from small articles and fallen from the space of the partitioning portion.

The upper surface of blocking member 35 is as shown in figure 3, when blocking member is located at the blocking position for plugging gap, compare sedan-chair The upper surface of railway carriage or compartment side door sill 31 and stop side door sill 32 is on the lower.In addition, its flat shape is formed to threshold 31,32 The geomery that gap is blocked.That is, with the positive wide somewhat big length by the gateway than cage side and threshold is compared 31st, the flat shape that 32 gap somewhat big width is constituted.

Moreover, the upper corner of the blocking member 35 is carried out chamfering.

The blocking member 35 is metal system or resin-made, if it is considered that processability and delaying between miscellaneous part If punching property etc., then resin piece is preferred.

The blocking member 35 is configured to the blocking position and Fig. 2 blocked in the gap by threshold 31,32 shown in Fig. 3 Moved between the retreating position of the shown lower section for keeping out of the way cage side threshold 31.That is, by drive mechanism described later along the upper of Fig. 3 The driving of lower and left and right directions.

Blocking member 35 is installed on vertically via the elastomers such as leaf spring 38 (being illustrated below as leaf spring 38) On the bracket 37 of configuration.Thus, blocking member 35 by supported by plate spring into can be along cage side threshold 31 and stop side door sill 32 Septal direction is swung.The leaf spring 38 with the identical part of blocking member 35 also as shown in Fig. 2 be divided, with bracket 37 Support the divided corresponding part of blocking member 35 respectively together.

Drive mechanism is as shown in Fig. 2 with positioning of components 40, the 1st linkage 50 and the 2nd linkage 60.

Positioning of components 40 is configured at the lower section of blocking member 35, engages with the bottom of bracket 37, usually makes the bracket 37 Decline, make retreating position of the blocking member 35 as shown in Figure 2 positioned at the lower section of cage side threshold 31.That is, positioning of components 40 As shown in figure 4, in part corresponding with the lower end side of bracket 37, with the recess 41 that incised notch is U-shaped.In the recess 41 Edge in diagram, integrally installed with engaging body 42.

In the recess 41, the engagement pin 371 inserted with the bottom side for being integratedly installed on bracket 37.The pressure structure Part 40 it is flat when by deadweight by the power to descent direction.If also, the positioning of components 40 declines, and is inserted in recess 41 Engagement pin 371 engage with engaging body 42 and be depressed, the blocking member set by bracket 37 and at an upper portion thereof via leaf spring 38 35 pressures.

1st linkage 50 starts work with the car door 25 shown in Fig. 2, in the enabling end (car of car door 25 Door 25 turns into the positions of standard-sized sheet) neighbouring open position set in advance, engage with the working component 70 of car door side, by sedan-chair The locomotivity in the enabling direction of railway carriage or compartment door 25, rises positioning of components 40.

1st linkage 50 is as shown in Fig. 2 with work connecting rod 51 and parallel rod 52.

The length direction pars intermedia in " く " shape portion 511 of connecting rod 51 of working passes through fulcrum rotatably pivot It is supported in cage side supporting member 53.In addition, the diagram top in the V shape portion 511, is obliquely integrally formed to diagram left There is the holding section 512 that the working component 70 with the side of car door 25 engages.Moreover, the diagram lower end in the V shape portion 511 is via fulcrum By can via fulcrum in the way of be linked to the supporting member 401 that the diagram left end in positioning of components 40 is integratedly erected Top.

The two ends of parallel rod 52 be rotatably linked to respectively via fulcrum above-mentioned supporting member 53, 401 bottom.The diagram right-hand member of positioning of components 40 is also provided with parallel rod 52 between the supporting member 53 of cage side.

Therefore, the 1st linkage 50 is, the starting with car door 25 of inclined holding section 512 for the connecting rod 51 that works Make and engage with the working component 70 for being arranged at door face board 25a sides, by the power of enabling direction (diagram left), and it is inverse to illustrating Clockwise is rotated.By the rotation, positioning of components 40 is set to be moved in parallel upward together with parallel rod 52.

As shown in Figures 3 and 4, the 2nd linkage 60 is formed between bracket 37 and the supporting member 63 of cage side, adjoint In the rising of positioning of components 40, make bracket 37 rise while transverse shifting.That is, the 2nd linkage 60 has 2 parallel rods 61st, 62, the two ends of these parallel rods are rotatably linked to bracket 37 and the support structure of cage side via fulcrum Part 63.In addition, in the fulcrum positioned at the side of supporting member 63 of these parallel rods 61,62, torsion spring 65 is provided with, to parallel rod 61st, 62 assign diagram clockwise rotatory force.Therefore, upward spring force is acted on by the torsion spring 65 when bracket 37 is flat.

If the parallel rod 61,62 of the 2nd linkage 60 is rotated clockwise from Fig. 4 state to diagram, by bracket 37 send out to diagram left and make it mobile to diagram top, to Fig. 3 state displacement.Thus, via leaf spring on bracket 37 Shown in 38 blocking members 35 from Fig. 3 above the retreating position to inclination of the lower section of the cage side threshold 31 shown in Fig. 2 installed Blocking position movement.

In the above-described configuration, at the position for closing an end closed in car door 25, as shown in Fig. 2 the side of car door 25 Work connecting rod 51 of the working component 70 not with the 1st linkage 50 engage, the 1st linkage 50 is not by from car door 25 The active force of side.Thus, positioning of components 40 is declined by deadweight, as shown in figure 4, the side of bracket 37 being inserted in its recess 41 Engagement pin 371 be depressed by the engaging with engaging body 42.Therefore, bracket 37 and at an upper portion thereof via leaf spring 38 set Blocking member 35 is located at the retreating position of the lower section of cage side threshold 31.

If the flat bed of car 4 rests against stop, car door 25 carries out starting work, and door face board 25a reaches enabling end (car door 25 Fully open position) neighbouring open position set in advance, then be arranged at door face board 25a working component 70 with constituting the 1st connecting rod The inclined holding section 512 of the work connecting rod 51 of mechanism 50 engages.Thus, work connecting rod 51 is opened the door by door face board 25a The locomotivity in direction (diagram left), is rotated counterclockwise to diagram.By the rotation of the diagram counterclockwise, work connecting rod 51 and flat Row connecting rod 52 rises positioning of components 40.

By the rising of positioning of components 40, the depressing force acted on by engaging body 42 shown in Fig. 4 is eliminated, via engagement pin 371 brackets 37 for being sticked in the engaging body 42 are risen by the spring force of torsion spring 65.Bracket 37 is by parallel rod 61,62 The supporting member 63 of cage side is installed in, therefore, during the rising, while to the movement of diagram left while rising.Thus, via Leaf spring 38 is installed on blocking member 35 on bracket 37 from the retreating position of the lower section of the cage side threshold 31 shown in Fig. 2 to inclination Blocking position movement shown in Fig. 3 of top.

Stopped to the action of the blocking position by the 1st linkage 50 to defined angle of rotation is rotated counterclockwise.That is, Constitute the 1st linkage 50 work connecting rod 51 inclined holding section 512 with if above-mentioned defined angle of rotation is rotated into Angle of inclination is set for the mode of horizontality.Thus, though door face board 25a become enabling end (full-gear) also after Continuous door opening action, the 1st linkage 50 also will not be rotated further, and blocking member 35 keeps the blocking position shown in Fig. 3.

In the blocking position, blocking member 35 blocks the gap between threshold 31,32, and therefore, small articles will not be from this Gap is dropped in well, can easily reclaim possibility.In addition, upper surface of the upper surface of blocking member 35 than threshold 31,32 More on the lower, therefore, the load of the object on threshold 31,32 will not apply to blocking member 35, be prevented from because being applied Loading causes the supporting part of blocking member 35 to damage.

Under the blocked state that the blocking member 35 blocks gap, if the load of car 4 significantly changes, car sometimes 4 temporarily can somewhat rise.Even if generating the temporary transient rising of such car 4, also due to the upper corner of blocking member 35 Chamfering has been carried out, and blocking member 35 is supported by leaf spring 38, without producing the problems such as damaging.

When such as the situation that the passenger taken in car 4 with full state disposably walks out car, car can be temporary transient Somewhat rise.Now, the blocking member 35 positioned at blocking position shown in Fig. 3 also rises, sometimes with the bottom of threshold 31,32 Side portion is abutted against.But, due to the upper corner quilt of the blocking member 35 opposed with the bottom side portion of stop side door sill 32 Chamfering is implemented, therefore the abutting power of the part is weakened, and is prevented from damaging caused by abutting.In addition, blocking member 35 Supported by leaf spring 38, therefore, in above-mentioned abutting, leaf spring 38 is also bent in the vertical direction, therefore is subtracted by its cushioning effect It is weak to be impacted caused by abutting, also it is prevented from damaging caused by abutting accordingly.

On the other hand, if car door 25 carries out closing action, be moved to it is defined close a position, then be arranged at door face board 25a Leave the holding section 512 of the working component 70 of side from the work connecting rod 51 for constituting the 1st linkage 50.Thus, originally from work The power that 70 pair of the 1st linkage 50 of component applies is released from, and positioning of components 40 is declined by deadweight.Thus, the 2nd linkage 60 from Fig. 3 state to rotating counterclockwise, and makes bracket 37 and the blocking member 35 installed over which leaf spring 38 is from shown in Fig. 3 Blocking position to mobile below diagram right bank, return to the retreating position of the lower section of cage side threshold 31.

Even if here, there is deviation in the interval in the gap between threshold 31,32, also due to by blocking member 35 via leaf spring 38 It is installed on bracket 37, is configured to swing to moving direction, is reliably blocked therefore, it is possible to deviate with not producing Gap.

In addition, in the case where leaf spring 38 has been bent, gap is produced in the holding section engaged with bracket 37 sometimes, if The gap, which sandwiches dust etc., can not then reset into original shape.It is therefore preferable that to being possible to that the part in the gap can be produced Implement the protection such as setting for being filled or covering in advance.

In the above-described embodiment, the 1st linkage 50 is when car door 25 is reached near enabling end (standard-sized sheet) Carve, engage with the working component 70 of car door side, blocking member 35 is moved to blocking position.In this composition, if Car, which is not opened near enabling end then blocking member, will not turn into blocked state, but in the embodiment party shown in following Fig. 5 It is configured in formula, blocking member is moved to blocking position in the stage earlier.

In this embodiment, the 1st linkage 50 is closing end (full close position) skew ground in advance to car door 25 The open position of setting, engages work connecting rod 51 and the working component 70 of the side of car door 25, by the evolution to car door 25 to Locomotivity, positioning of components 40 is increased.In addition, supported into relative to car door 25 can for the working component 70 of the side of car door 25 Direction (diagram left and right directions) is opened and closed along it relatively to slide.Also, the working component 70 is configured to, usually assign towards with The spring force for the engagement direction that the connecting rod 51 that works engages, if by the engaging with the connecting rod 51 that works by engaging reaction force The above-mentioned spring force of resistance, is relatively slided with the side of car door 25.

Specifically, as illustrated, from the upper end in V shape portion 511, with aforementioned embodiments on the contrary to diagram right side It is formed obliquely the holding section 512A for the work connecting rod 51 for constituting the 1st linkage 50.The working component 70 of the side of car door 25 is pacified Diagram left part loaded on the movable support bracket 71 grown crosswise, by the elongated hole 711 and the side of car door 25 that are formed at the movable support bracket 71 Supporting pin 251 engaging, support into can along car door 25 opening and closing direction slide.In addition, the movable support bracket 71 with Spring 72 is set between car door 25, usually working component 70 assigned towards the engagement direction (figure engaged with work connecting rod 51 Show left) spring force.If working component 70 engages with work connecting rod 51, it is set to be engaged after rotating defined angle of rotation Reaction force, then resist the spring force of spring 72 and relatively slided with the side of door 25.

In the above-described configuration, when car door 25 is located at and closes end (full close position), as shown in figure 5, the side of car door 25 Work connecting rod 51 of the working component 70 not with the 1st linkage 50 engages, and the 1st linkage 50 is not by from the side of car door 25 Active force.Thus, positioning of components 40 is declined by deadweight, as shown in figure 4, the side of bracket 37 being inserted into its recess 41 Engagement pin 371 is depressed by the engaging with engaging body 42, bracket 37 and the blocking structure set at an upper portion thereof via leaf spring 38 Part 35 is located at the retreating position of the lower section of cage side threshold 31.

If the flat bed of car 4 rests against stop, car door 25 carries out starting work, reach to car door 25 to close an end (fully closed Position) offset open position set in advance, then as shown in figure 5, being arranged at the working components 70 of door face board 25a sides with constituting the The holding section 512A of the work connecting rod 51 of 1 linkage 50 abuts engaging.The abutting clamped position is and aforementioned embodiments Open position set in advance is compared near enabling end (fully open position), is the open position of the earlier stage since opening the door.

Engaged by the abutting, same with aforementioned embodiments, work connecting rod 51 is by the enabling direction of car door 25 The locomotivity of (diagram left), centered in the fulcrum that the pars intermedia in its V shape portion 511 is set, is rotated counterclockwise to diagram. By the rotation of the diagram counterclockwise, work connecting rod 51 and parallel rod 52 rise positioning of components 40.Pass through the positioning of components 40 rising, blocking member 35 from the retreating position of the lower section of cage side threshold 31 to inclination above Fig. 3 shown in blocking position Put movement.

By this to blocking position action, work connecting rod 51 stop rotation counterclockwise, the work structure of the side of car door 25 Part 70 is stopped by engaging reaction force.Now, car door 25 is the mobile midway to enabling end, is proceeded left to diagram The movement of side.Thus, the working component 70 for being supported in movable support bracket 71 resists the spring force of spring 72, with car door 25 relatively Slide, it is allowed to the movement to diagram left of car door 25.

That is, the 1st linkage 50 is worked at the time of since the enabling of car door 25 earlier, make blocking member 35 Be moved to blocking position, therefore, car door 25 enabling halfway, even if passenger come in and go out and the small articles that dropped, small articles Well will not be fallen to from gap portion, can easily reclaimed.

On the other hand, in the case where car door 25 carries out closing action, the of short duration period after a beginning is closed, spring 72 is stored Can, therefore, only car door 25 is moved, and the working component on movable support bracket 71 maintains to stop.If as defined in car door 25 is moved to A position is closed, then the supporting pin 251 of the side of car door 25 is moved to the diagram right-hand member side of elongated hole 711, makes to move support via elongated hole 711 Frame 71 and working component 70 are moved to diagram right.Thus, work connecting rod 51 of the working component 70 from the 1st linkage 50 of composition Holding section 512A leave.So, the power applied originally from 70 pair of the 1st linkage 50 of working component is released from, positioning of components 40 decline due to deadweight, therefore, make bracket 37 and the blocking member 35 installed above it via leaf spring 38 from shown in Fig. 3 Blocking position is moved below being tilted to the right, and returns to the retreating position of the lower section of cage side threshold 31.

That is, make the blocking of the on-off action and blocking member 35 of car door 25 that there is hysteresis characteristic, therefore energy between acting Blocking member 35 is enough set to carry out blocking action in the optimal open position of car door 25.

In addition, in the above-described embodiment, the upper surface of blocking member 35 is located in blocking member as shown in Figure 3 During blocking position than cage side and stop side door sill 31,32 upper surface more on the lower, but the application utility model is not limited to This or, the upper surface of blocking member 35 is turned into and cage side and stop side door sill 31,32 when positioned at blocking position The roughly the same height in upper surface.That is, enter in the way of gap of the width of blocking member 35 entering threshold 31,32 Row size is set, and the upward stroke to the blocking member 35 is so that the upper surface of blocking member 35 turns into upper with threshold 31,32 The mode of the roughly the same height in surface is set.In this case, above and below the use of leaf spring 38 of supporting blocking member 35 The stronger structure of direction rigidity.

If so constituting, flat gateway very close to each other between threshold 31,32 can be formed in.
