The upper surface of blocking member 35 as shown in Figure 7 to 9, than the upper surface of cage side threshold 31 and stop side door sill 32 On the lower.In addition, its flat shape is formed to the geomery for blocking in the gap of threshold 31,32 as shown in Figure 6. That is, its flat shape as the cage side shown in than Fig. 2 gateway positive wide somewhat big length and than Fig. 7 to Fig. 9 institutes Show that the gap of threshold 31,32 somewhat big width is constituted.

In addition, its cross section is set to the shape of lengthwise, in the opposed portion opposed with the diagram right flank of stop side door sill 32 It is formed with recess 35a.Recess 35a is the screw 36a set for the diagram right flank avoided in stop side door sill 32 head Portion and set.Screw 36a is used to install the board member 36 for marking off lower interlayer space.Moreover, the top of the blocking member 35 Corner is carried out chamfering 35b.

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

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

Blocking member 35 is installed on via the elastic component (illustrating below as leaf spring) 52 of leaf-spring-like and is arranged on driving On the bracket 51 of the side of mechanism 41.Thus, blocking member 35 is supported into by leaf spring 52 can be along cage side threshold 31 and stop side door The septal direction (being also relative to the fore-and-aft direction for sliding moving direction) of sill 32 is swung.The bracket 51 and leaf spring 58 also exist It is divided with the identical part of blocking member 35, the divided corresponding part of blocking member 35 is supported respectively.

Drive mechanism 41 is configured to, can with car door 25 on-off action, as shown in Figures 3 and 4, with car door The working component 42 of 25 sides engages.Then, the power being subject to by the engaging with the working component 42 from working component 42 is become The slip moving direction of blocking member 35 is changed to, blocking member 35 is driven to moving direction is slided.That is, drive 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 blocking position of the blocking member 35 shown in Fig. 7 is slided movement, if by car door 25 to close a movement at end and Assigned position is closed, then blocking member is slided the retreating position being moved to shown in Fig. 8 and Fig. 9.

In this embodiment, drive mechanism 41 as shown in Figure 5, Figure 6, has：4 connecting rods 46,47,48,49；And support Frame 51, each one end via connection shaft 50 and these connecting rods rotatably links.4 connecting rods 46,47,48,49 are passed through Rotatably it is supported on and is arranged on the supporting member 44 of the side of car 4 by pivotal support axle 45.

Among these 4 connecting rods, the connecting rod 47,48 of inner side is used to link driving, and their other end is via connection shaft 54 With connecting rod 55.Connecting rod 47,48 and connecting rod 55 on the inside of this are used to make blocking member 35, accompany its bracket 51 and leaf spring The part of 52 quilt or so segmentation is interlocked, and these divided parts are integrally acted.In the diagram right-hand member of the connecting rod 55 Extension spring 56 is provided between supporting member 44, usually drive mechanism 41, which is assigned, makes bracket 51 lateral from supporting member 44 The power in the direction that diagram lower section is sent out.

In the pivotal support axle 45 for the connecting rod 46 for constituting the drive mechanism 41, integrally installed with the cardinal extremity of bar component 58 Portion.In the leading section of the bar component 58, work pin 59 is equipped with.The upper side of the work pin 59 as shown in Figures 3 and 4, is matched somebody with somebody 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, with the flat part 42a and rake 42b engaged with work pin 59.Flat part 42a door 25 be located at shown in Fig. 2 when closing end position, as indicated with broken lines in fig. 4, as above pushing away, make bar structure work pin 59 The state that part 58 and the pivotal support axle 45 integral with it are rotated clockwise to diagram.By the rotation, turn into and pivotal support The connecting rod 46 of the one of axle 45 and other connecting rods 47,48,49 linked via bracket 51 also resist the anti-of reaction force spring 56 Active force and to the diagram state that is rotated clockwise.That is, drive mechanism 41 passes through pin 59 and the working component 42 of working Flat part 42a engages, and is retained as the 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 the retreating position shown in Fig. 8 and Fig. 9.

The state of the Fig. 5 maintains the duration suitable with the length X of the flat part 42a shown in Fig. 4.That is, even if passing through door 25 start work and door face board 25a to diagram right move, work pin 59 engage with flat part 42a during, 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 46th, 47,48,49 and pivotal support axle 45 and be applied in the reaction based on reaction force spring 56 shown in Fig. 5 and Fig. 6 Power, the rotatory force that diagram is counterclockwise.Thus, work pin 59 engages with rake 42b, and they counterclockwise turn to diagram Dynamic, the blocking member 35 supported by bracket 51 and at an upper portion thereof via leaf spring 52 is sent out from Fig. 5 state to Fig. 6 state, to Blocking position shown in Fig. 7 enters line slip movement.

Here, described reaction force spring 56 finally connects via drive mechanism 41 and the grade of bracket 51 with blocking member 35 Knot, for acting the blocking position shown in blocking member 35 to Fig. 6 and Fig. 7 via drive mechanism 41.Therefore, the reaction force Spring 56 is used as the working spring function (also referred to as working spring 56 below) for making blocking member 35 be acted to blocking position.

So, drive mechanism 41 is moved to defined open position by car door 25 from Men Duan is closed, thus with car door side The clamping force of working component 42 be released from, it is allowed to moved in the presence of working spring 56 to the slip of blocking position.In addition, Car door 25 when closing as described later, to a mobile midway at end is closed, engage with the working component 42 of car door side, by Slide the blocking member 35 positioned at blocking position to the locomotivity of car door 25 and be moved to retreating position.

As shown in Figure 7 to 9, being provided with supporting member 44 stops at the above-mentioned slip movement of blocking member 35 The limiter 61 of blocking position and retreating position.Figure 10 is that the part of limiter 61 is taken out to the figure represented.The limiter 61 has 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, matched somebody with somebody between these It is equipped with the abutting member 63 from the extended section L-shaped of the bracket 51 of the side of blocking member 35.

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

Constitute drive mechanism 41 pivotal support axle 45 among, be configured at Fig. 2, Fig. 3 right-hand member pivotal support axle 45 with The one of bar component 58, is to be engaged with the working component 42 of the side of car door 25 by being erected on the work pin 59 of bar component 58 and carried out 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 The revolving force of the opposite direction in the direction of 42 rotations for engaging and producing.

By this composition, in the state of work pin 59 does not engage with working component 42, work pin can be made to return all the time To correct position.

In the above-described configuration, when car door 25 is in the position for closing an end, the working component of the side of car door 25 shown in Fig. 3 42 as indicated with broken lines in fig. 4, is engaged by its flat part 42a come the work pin 59 with the side of drive mechanism 41, drive mechanism 41 is supported The spring force of anti-working spring 56 and the state for being retained 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 bottom of cage side threshold 31.

If the flat bed of car 4 rests against stop, car door 25 starts door opening action.Start in the work that starts of the car door 25 Afterwards, within one section of period, work pin 59 engage with flat part 42a, when engaging persistently suitable with flat part 42a length X It is long.Afterwards, if car door 25 is moved to defined open position, work pin 59 such as Fig. 4 of drive mechanism 41 solid line institute is constituted Show, leave, engage with rake 42b from the flat part 42a of working component 42.

That is, drive mechanism 41 is moved to defined open position, work pin 59 and car door by car door 25 from Men Duan is closed The clamping force of the working component 42 of side is released from, by the reaction force of working spring 56, by bracket 51 and its supported it is stifled Plug member 35 is sent out from Fig. 5 state to Fig. 6 state.Therefore, blocking member 35 is from the retreating position shown in Fig. 8, Fig. 9 to figure Show that movement is slided in left, reach the blocking position shown in Fig. 7.Then, the leading section (diagram left part) of the blocking member 35 with The diagram right flank of stop side door sill 32 is abutted, and the gap between threshold 31,32 is blocked.

Here, in the case of the intentional behavior for pushing door open has been carried out in car travel, if by door opening With it if linkedly blocking member is protruded immediately, then it is contemplated that due in traveling, therefore prominent blocking member meeting With the component contact of stop side and it is damaged.

But, in embodiments of the present invention, even if door is starts work, blocking member also will not be immediately to blocking position It is prominent, but by door reach it is set in advance as defined in open position it is just prominent to blocking position, therefore pass through car travel In opening door operation, also result in the time untill car jerk is stopped, prominent blocking member and stop side joint can be prevented Touch and it is damaged.

In general, in lift appliance, being provided with the traveling of car in the case of deliberately opening door and detecting the feelings The door switch of condition, is acted by the disconnection of the door switch and stops car jerk.As described above, in embodiments of the present invention In, even if door carries out starting work, blocking member also will not be prominent to blocking position immediately, and rule set in advance are reached by door Fixed open position is just prominent to blocking position, and therefore, during this period, car jerk is stopped.That is, it is prominent to blocking position after a stop Go out, therefore, will not produce prominent blocking member and stop component contact and breakage the state of affairs.

Thus, so that blocking member protrude action, door defined open position as corresponding to detecting sedan-chair Railway carriage or compartment traveling in enabling and car jerk stop untill the corresponding open position from the distance for closing Men Duanqi of opening time side Formula, the length X of the flat part 42a shown in setting 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 Alignment error and it is different.In addition, also because of the car downward shift before and after car guiding device when loosening, boarding, size is produced Change dynamic.

In embodiments, it is configured to, blocking member 35 is installed on bracket 51 via leaf spring 52, can be moved along slip The swing in direction.That is, position (blocking position) place's swing that blocking member 35 can be after protrusion.In addition, by plate Spring 52 to stop side (diagram left) push, as if by car direction (diagram right) if pressing if retract, pressing force solution Except the construction for then returning to original blocking position.

By the construction, it can be configured to, in running clearance than in the case of generally narrow, by cage side, (diagram is right Side) push back, it is prominent to blocking position in the case of wider, the higher blocked state of closed stratum can be obtained.

So, when blocking member 35 is located at blocking position, the gap between threshold 31,32 is blocked, therefore, small articles will not Drop in well, can easily reclaim 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 in the damage of the supporting part of blocking member 35 caused by load.

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 the temporary transient rising of such car 4 is generated, also due to the upper corner of blocking member 35 Chamfering 35b has been carried out, and blocking member 35 is supported by leaf spring 52, 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 4 can be temporary transient Somewhat rise.Now, the blocking member 35 positioned at blocking position shown in Fig. 6 also rises, sometimes with stop side door sill 32 Bottom side portion is abutted against.But, due to the upper corners of the blocking member 35 opposed with the bottom side portion of stop side door sill 32 Portion has been carried out chamfering 35b, therefore the abutting power of the part is weakened, and can prevent from damaging caused by abutting.In addition, blocking Component 35 is supported by leaf spring 52, therefore, in above-mentioned abutting, and leaf spring 52 is also bent in the vertical direction, therefore is buffered by it Declines impact caused by abutting, accordingly can also prevent from damaging caused by abutting.

On the other hand, if car door 25 carries out closing action, the midway for closing an end position is reached in door, drive mechanism is constituted 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 (movement for closing a direction) to diagram left, make work pin 59 mobile to diagram top, make bar component 58 and and its The pivotal support axle 45 of one is rotated clockwise to diagram.By the rotation, with the connecting rod 46 of the one of pivotal support axle 45 and The reaction force that other connecting rods 47,48,49 linked via bracket 51 also resist working spring 56 is rotated clockwise to diagram.

That is, drive mechanism 41 is engaged with the rake 42b of working component 42 by the pin 59 that works and is returned as shown in Fig. 5 State, bracket 51 and at an upper portion thereof via leaf spring 52 support blocking member 35 to Fig. 8 and Fig. 9 shown in retreating position move It is dynamic.The action is tied at the time of the clamped position for the pin 59 that works is changed into flat part 42a from the rake 42b of working component 42 Beam, after, untill car door 25 reaches and closes an end position, keep the state.

So, when closing of car door 25, is engaging with the working component 42 of car door side to closing a mobile midway at end, The blocking member 35 positioned at blocking position is set to be slidably moved to retreating position by the locomotivity of car door 25.

The slip of blocking member 35 is moved through 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 reliably prevent blocking member 35 from not stopping at correct position and run it is excessive and its His part collides and produces damage.Even if in addition, assume to generate operation it is excessive, also due to blocking member 35 is by leaf spring 52 Support, therefore, can be buffered by the flexure of leaf spring 52 and be impacted caused by the collision with miscellaneous part, can prevent from reaching part The degree of damage.

In addition, in the case where leaf spring 52 has been bent, gap is produced in the holding section engaged with bracket 51 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 addition, leaf spring 52 has flexure function vertically as described above.Thus, in order to more effectively produce The flexure of above-below direction, can also form at least one towards horizontal bending section so that produce in the longitudinally intermediate portion of leaf spring 52 The spring force of longitudinal direction.As the bending section, the bending of leaf spring 52 is section V-shaped, such as Figure 132 institutes as shown in figure 11 by Ke Yishi Show, be bent into semicircle.And then or, make the bending of V-shaped continuous multiple up and down or make semicircle continuous up and down Multiple bendings to form S fonts.

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

In addition, the snap portions engaged with the working component 42 of the side of car door 25 of drive mechanism 41, being provided with work The position of pin 59, is set to the positive wide outside of the gateway 24 for the car 4 being opened and closed by car door 25.

In the above-described embodiment, drive mechanism 41 is the locomotivity for blocking member 35 by the opening and closing force transformation of door The drive mechanism of such machinery is not limited to come the drive mechanism of the composition being mechanically driven, but the present invention.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 drive mechanism.

In addition, in the above-described embodiment, drive mechanism 41 is to make blocking member 35 slide from retreating position to be moved to Blocking position.But, problem of the invention is, 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 defined open position set in advance when the gap of railway carriage or compartment side door sill is blocked, thus, lead to The opening door operation crossed in car travel can also prevent breakage of blocking member etc. caused by the contact with stop side, from the class From the point of view of topic, for example, it can also apply to also carry out to transverse shifting while making the retreating position of blocking member from below increase The structure of blocking action.Therefore, drive mechanism can also blocking member is slided movement, moreover it is possible to above and below combination Move with transverse shifting to move.

Several embodiments of the invention is explained above, but these embodiments are intended only as example and pointed out, and It is not intended to limit interest field.These new embodiments can be implemented in other various modes, can not depart from main idea In the range of carry out it is various omit, displacement and change.These embodiments and its deformation are contained in the scope and main idea of invention, and And it is contained in invention and its equivalent scope described in claims.
