In addition, the blocking member 35 is made of metal or resin system, if it is considered that processability and with other component it Between resiliency etc. if, then resin piece is preferred.

The blocking member 35 is configured to the blocking position and Fig. 8 that the gap shown in Fig. 7 by threshold 31,32 blocks And (Fig. 9 is to more clearly see for sliding movement between the retreating position of the lower part shown in Fig. 9 for keeping out of the way cage side threshold 31 The figure examined the state of the blocking member 35 of retreating position and show the removing of a part of component from Fig. 8).Also, after passing through The driving mechanism 41 stated is slided between above-mentioned blocking position and retreating position with the on-off action of car door 25 Driving.

Blocking member 35 is installed on setting via the elastic component (leaf spring is used as to illustrate below) 52 of leaf-spring-like and is driving On the bracket 51 of 41 side of mechanism.Thus, blocking member 35 is supported by leaf spring 52 at can be along cage side threshold 31 and stop side door The septal direction (and front-rear direction relative to sliding moving direction) of sill 32 is swung.The bracket 51 and leaf spring 58 also exist Part identical with blocking member 35 is divided, and supports the divided corresponding part of blocking member 35 respectively.

Driving mechanism 41 is configured to, can be with the on-off action of car door 25, as shown in Figures 3 and 4, with car door The working component 42 of 25 sides engages.Then, will become by with the power being subject to and the engaging of the working component 42 from working component 42 It is changed to the sliding moving direction of blocking member 35, blocking member 35 is driven to sliding moving direction.That is, driving mechanism 41 links In blocking member 35, with the on-off action of car door 25, defined open position is reached from Men Duan is closed by car door 25 And slide blocking member 35 to blocking position shown in Fig. 7 and move, if being existed by car door 25 to a movement at end is closed Specified position is closed, then blocking member sliding is made to be moved to Fig. 8 and retreating position shown in Fig. 9.

In this embodiment, driving mechanism 41 is as shown in Figure 5, Figure 6, comprising: 4 connecting rods 46,47,48,49；And support Frame 51 rotatably links via connection shaft 50 and each one end of these connecting rods.4 connecting rods 46,47,48,49 pass through It is rotatably supported on by pivotal support axis 45 on the supporting member 44 for being set to 4 side of carriage.

In these 4 connecting rods, the connecting rod 47,48 of inside is that connection driving is used, their other end is via connection shaft 54 With connecting rod 55.The bracket 51 and leaf spring that connecting rod 47,48 and connecting rod 55 on the inside of this are used to make blocking member 35, accompany it 52 part by left and right segmentation is interlocked, these divided parts integrally act.In the diagram right end of the connecting rod 55 Extension spring 56 is provided between supporting member 44, usually to driving mechanism 41 imparting make bracket 51 from 44 side of supporting member to The power in the direction that diagram lower section is sent out.

In the pivotal support axis 45 for the connecting rod 46 for constituting the driving mechanism 41, integrally installed with the cardinal extremity of bar component 58 Portion.In the front end of the bar component 58, it is vertically equipped with work pin 59.The upper side of the work pin 59 is as shown in Figures 3 and 4, matches Being set to can engage with the working component 42 being integrally provided on the door face board 25a of car door 25.

Working component 42 is as shown in figure 4, have the flat part 42a and rake 42b engaged with work pin 59.Flat part 42a door 25 be located at it is shown in Fig. 2 close end position when, as indicated with broken lines in fig. 4, become and work pin 59 above pushed away, make bar structure The state that part 58 and the pivotal support axis 45 integrated with it are rotated clockwise to diagram.By the rotation, become and pivotal support The connecting rod 46 of the one of axis 45 and the anti-of reaction force spring 56 is also resisted via other connecting rods 47,48,49 that bracket 51 links Active force and to the diagram state that is rotated clockwise.That is, driving mechanism 41 passes through work pin 59 and working component 42 42a engaging in flat part is maintained as state shown in fig. 5, bracket 51 and the blocking member supported at an upper portion thereof via leaf spring 52 35 are held in Fig. 8 and retreating position shown in Fig. 9.

The state of the Fig. 5 maintains the comparable duration of length X with flat part 42a shown in Fig. 4.That is, even if passing through door 25 start work and door face board 25a is mobile to diagram right, during the pin 59 that works engages with flat part 42a, also maintain Fig. 5 State.

If car door 25 is moved to defined open position from Men Duan is closed, such as Fig. 4's is shown in solid, and work pin 59 is from flat Portion 42a leaves, and engages to rake 42b.In bar component 58 with work pin 59, pass through the connecting rod linked via bracket 51 46,47,48,49 and pivotal support axis 45 and be applied Fig. 5 and the reaction shown in fig. 6 based on reaction force spring 56 Power, diagram rotatory force counterclockwise.Thus, work pin 59 engages with rake 42b, they counterclockwise turn to diagram It is dynamic, it is sent out by bracket 51 and at an upper portion thereof via the blocking member 35 that leaf spring 52 supports from the state of Fig. 5 to the state of Fig. 6, to Blocking position shown in Fig. 7 carries out sliding movement.

Here, the reaction force spring 56 finally connects with blocking member 35 via driving mechanism 41 and bracket 51 etc. Knot, for acting blocking member 35 to Fig. 6 and blocking position shown in Fig. 7 via driving mechanism 41.Therefore, the reaction force Spring 56 functions (also referred to as working spring 56 below) as the working spring for acting blocking member 35 to blocking position.

In this way, driving mechanism 41 is moved to defined open position from Men Duan is closed by car door 25, thus with car door side The clamping force of working component 42 be released from, allow mobile to the sliding of blocking position under the action of working spring 56.In addition, Car door 25 it is as described later when closing, to a mobile midway at end is closed, engage with the working component 42 of car door side, by To car door 25 mobile power and make positioned at blocking position blocking member 35 sliding be moved to retreating position.

As shown in Figure 7 to 9, being provided on supporting member 44 stops at the above-mentioned sliding movement of blocking member 35 The limiter 61 of blocking position and retreating position.Figure 10 is that the figure indicated is taken out in 61 part of limiter.The limiter 61 tool There is the U-shaped component for being fixedly installed on supporting member 44, its two medial surface is provided with the bolsters such as rubber 62, matches between these It is equipped with the abutting member 63 for the section L-shaped being extended from the bracket 51 of 35 side of blocking member.

By this composition, by out of, the U-shaped component of abutting member 63 and limiter 61 that bracket 51 is extended two Side abuts, thus it enables that the sliding movement of blocking member 35 correctly stops at blocking position and retreating position.In addition, rubber The bolster 62 of glue etc. can be set in either or both of limiter 61 and abutting member 63.

Among the pivotal support axis 45 for constituting driving mechanism 41, be configured at the pivotal support axis 45 of the right end of Fig. 2, Fig. 3 with 58 one of bar component, is carried out and the work pin 59 for being erected on bar component 58 engages with the working component 42 of 25 side of car door The rotary shaft of rotation.Be provided with torsionspring 65 as shown in Figure 7 to 9 in the rotary shaft, assign by with working component 42 engaging and generate rotation direction opposite direction rotary force.

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 The flexure of up and down direction can also form at least one towards lateral bending section in the longitudinally intermediate portion of leaf spring 52, so that generating Longitudinal spring force.It as the bending section, can be, be section V-shaped by 52 bending of leaf spring, such as Figure 12 institute as shown in figure 11 Show, is bent into semicircle.In turn, it is also possible to make the bending of V-shaped continuous multiple up and down or makes semicircle continuous up and down Multiple bendings to form S font.

If formed in this way, leaf spring 52 can also be made effectively to be bent to the longitudinal direction parallel with plate face.

In addition, the engaging part of driving mechanism 41 engaged with the working component 42 of 25 side of car door, being provided with work The position of pin 59 is set as the wide outside in the front of the entrance 24 for the carriage 4 being opened and closed by car door 25.

In the above-described embodiment, driving mechanism 41 is the mobile power by the opening and closing force transformation of door for blocking member 35 Come the composition mechanically driven, but driving mechanism of the invention is not limited to the driving mechanism of such machinery.For example, Can be electrically detection door reach as defined in open or closed position come make the drivers such as motor work and move blocking member Dynamic, such driving mechanism.

In addition, in the above-described embodiment, driving mechanism 41 is to be moved to blocking member 35 from retreating position sliding Blocking position.But problem of the present invention is that, with the on-off action of door linkedly with blocking member by stop side door sill and sedan-chair It is just prominent to blocking position by reaching preset defined open position when the gap blocking of compartment side door sill, lead to as a result, The opening door operation crossed in car travel can also prevent because with the breakage etc. of blocking member caused by the contact of stop side, from the class From the point of view of topic, such as it can also apply to carry out the retreating position of blocking member from below also to transverse shifting while rising The structure of blocking movement.Therefore, driving mechanism is also possible to not only make blocking member sliding movement, moreover it is possible to which combination is up and down It moves with transverse shifting and is moved.

Several embodiments of the invention is explained above, but these embodiments are intended only as example and prompt, and It is not intended to limit interest field.These new embodiments can be implemented with various other ways, can not depart from main idea In the range of carry out various omissions, substitutions and changes.These embodiments and modifications thereof are contained in the range and main idea of invention, and And it is contained in invention and its equivalent range documented by claims.
