In addition, the plug members 35 can be metal system or it is resinous any one, if but in view of processability or with Resiliency between miscellaneous part etc., then can use resin material.

The plug members 35 be configured to shown in Fig. 6 block threshold 31,32 between gap blocking position, with The bottom of the threshold 31 positioned at cage side shown in Fig. 7 and Fig. 8 and the upper surface of plug members 35 and the lower surface of threshold 31 Between keep moving between the retreating position at interval that (Fig. 8 is to easily observe the state of the plug members 35 at retreating position And eliminate a part of part and the figure shown from Fig. 7).And then, diagonally driven by linkage 41 described later and along with The on-off action of car door 25 is moved between above-mentioned blocking position and retreating position.

Plug members 35 are arranged on via leaf spring 52 and are arranged on the support 51 of the side of linkage 41.Linkage 41 is constituted For can the action component 42 with the side of car door 25 engages as shown in Figure 3 along with the on-off action of car door 25.And then, will The power born by the engaging with the action component 42 from action component 42 is changed to plug members 35 in above-mentioned blocking The moving direction (diagram direction) from left side towards lower right side moved between position and retreating position, so that by the edge of plug members 35 The moving direction drives.

In this embodiment, linkage 41 has 4 connecting rods 46,47,48,49 as shown in Figure 4, Figure 5, and via even The support 51 that knot axle 50 rotatably links with each one end of above-mentioned connecting rod.4 connecting rods 46,47,48,49 are via pivot Fulcrum 45 and be rotatably supported on and be arranged on the supporting member 44 of the side of car 4.

The connecting rod 47,48 of inner side in above-mentioned 4 connecting rods is the connecting rod for linking driving, and their other end is via link Axle 54 and link with connecting rod 55.Tensioning is provided with extension spring 56 between the diagram right-hand member and supporting member 44 of the connecting rod 55, Linkage 41 assigns the power in the direction for making support 51 be moved in parallel towards the side of supporting member 44.The base end part of bar 58 is integratedly pacified Mounted in the pivot fulcrum 45 for the connecting rod 46 for constituting the linkage 41.Erected in the leading section of the bar 58 and be provided with action pin 59.

Herein, moving direction of the pivot fulcrum 45 by plug members 35 along foregoing blocking position and retreating position is (from diagram Left is towards lower right) driving, therefore, as shown in Figure 6 to 8, tilted relative to vertical direction towards diagram Right deviation direction.It is adjoint In this, 45 connecting rods 46 and bar 58 for being installed on the pivot fulcrum are tilted relative to horizontal direction towards diagram bottom right.Also, supply connecting rod The link surface 51a of 41 supports 51 linked and the bearing-surface 44a of supporting member 44 are similarly relative to horizontal direction towards diagram Bottom right is tilted.In addition, other connecting rods 47,48,49 for constituting linkage 41 are also tilted in the same direction.

I.e., 4 connecting rods 46,47,48,49, bar 58 and the pivot fulcrum 45 that rotates them are set to and plug members Moving direction (from left is illustrated towards lower right) corresponding angle of inclination between blocking position and retreating position.

On the other hand, the action pin 59 for erecting the leading section for being arranged on bar 58 is vertically arranged, the upper side of the action pin 59 The action component 42 that face is configured to the door-plate 25a sides with being provided integrally at car door 25 as shown in Figure 3 engages.I.e., move Make pin 59 and engaging abutted with action component 42 by the opening action of car door 25 to predetermined open position, make bar 58 and with The pivot fulcrum 45 of one rotated in an anti-clockwise direction towards diagram.

By the rotation, other connecting rods 47,48,49 linked with the connecting rod 46 of the one of pivot fulcrum 45 and via support 51 Also overcome the tension force of extension spring 56 and rotated in an anti-clockwise direction towards diagram.By the action of the linkage 41, support 51 and warp Retreating position shown in plug members 35 from Fig. 4 and Fig. 7, Fig. 8 at an upper portion thereof is supported as leaf spring 52 towards Fig. 5 and Fig. 6 institutes The blocking position shown stretches out.The stretching direction is directed towards the upper left direction shown in Fig. 7, Fig. 8.

Herein, foregoing extension spring 56 finally links via linkage 41 and the grade of support 51 with plug members 35.The drawing Spring 56 assigns the direction returned towards the retreating position shown in Fig. 4 and Fig. 7, Fig. 8 via linkage 41 to plug members 35 Power.Thus, the extension spring 56 (hereinafter referred to as resets as the back-moving spring function for making plug members 35 return to retreating position Spring 56).

So, linkage 41 by the opening action of car door 25 to predetermined open position its action pin 59 such as Fig. 3 The shown action component 42 with the side of car door 25 engages, bear towards the locomotivity of the opening direction of car door 25 and make be located at keep out of the way The plug members 35 of position overcome the elastic force of back-moving spring 56 to be obliquely moved to blocking position.

Relative to the above-mentioned movement of plug members 35, the stop part that it will be made to stop in blocking position and retreating position 61 are arranged on supporting member 44 as shown in Figure 6 to 8.The part of stop part 61 is taken out and shown by Fig. 9.The stop part 61 has There is the U-shaped member for being fixedly installed on supporting member 44, its two medial surface is provided with the bolsters such as rubber 62, and between them Configure the abutment 63 from the extended section L-shaped of the support 51 of the side of plug members 35.

According to the structure, by the abutment 63 being extended from support 51 and the two of the U-shaped member of stop part 61 Side is abutted, and the movement of plug members 35 can be made correctly to stop in blocking position and retreating position.In addition, rubber etc. is slow Stamping 62 can be arranged at either one or both sides in stop part 61 and abutment 63.

Constitute the pivot fulcrum of the one of bar 58 of right-hand member in the pivot fulcrum 45 of linkage 41, with configuration in Fig. 2, Fig. 3 It is by erecting the rotation that the action pin 59 of setting abuts engaging with the action component 42 of the side of car door 25 and rotated on the bar 58 Rotating shaft.Torsion spring 65 is set as shown in Figure 6 to 8 in the rotary shaft, and imparting is produced because the rotary shaft engages with action component 42 The revolving force of the opposite direction of the direction of rotation of raw rotation.

According to the structure, in the state of action pin 59 does not engage with action component 42, action pin can be made to return all the time Correct position.

In said structure, when car door 25 is in the state closed, the action component of the side of car door 25 shown in Fig. 3 42 do not abut engaging with the action pin 59 of the side of linkage 41, and linkage 41 is not subject to the effect from the side of car door 25 Power.Therefore, plug members 35 and the support 51 of the plug members 35 is supported by the tension force of the back-moving spring 56 shown in Fig. 4 Returned towards the layback of supporting member 44, plug members 35 are held on table in the bottom of cage side threshold 31 as shown in Figure 7 and Figure 8 Face is in the attitude of horizontality and is located at the retreating position that interval is kept between the lower surface of cage side threshold 31.

If car 4 is stopped in hall, car door 25 carries out opening action and moved towards predetermined open position, then sets Action component 42 in door-plate 25a sides with constituting the action pin 59 of linkage 41 abuts engaging, and the opening by door-plate 25a is dynamic Make power and the bar 58 for being provided with action pin 59 is rotated in an anti-clockwise direction centered on pivot fulcrum 45 towards diagram.

By the action, linkage 41 overcomes the tension force of back-moving spring 56 and rotated in the same direction, make support 51 with And the plug members 35 supported by the support 51 stretch out from Fig. 4 state towards Fig. 5 state.Now, due to constituting linkage 41 bar 58 and 4 connecting rods 46,47,48,49 are tilted as previously described, therefore, and plug members 35 are keeping horizontality Obliquely moved under attitude.Therefore, retreating position of the plug members 35 from the bottom of the cage side threshold 31 shown in Fig. 7, Fig. 8 Towards the movement of diagram left, the blocking position shown in Fig. 6 is reached.

In the blocking position, plug members 35 block the gap between threshold 31,32, and therefore, small article will not be from the gap Fall in pit, can easily reclaim.Also, the upper surface of plug members 35 is leaned on positioned at the upper surface than threshold 31,32 The position of lower section, therefore, the load of the object on threshold 31,32 will not put on plug members 35, be prevented from because applying The damage of the support of the plug members 35 caused added with load.

Under the blocked state that gap is blocked by the plug members 35, if the load of car 4 significantly changes, car 4 has When temporarily can rise slightly.Even if producing the temporary rising of this car 4, because the upper corner to plug members 35 is real The problems such as applying chamfering 35b and plug members 35 supported by leaf spring 52, therefore damage will not be produced.

Such as the passenger in car 4 is taken with full state once under whole in the case of elevator, car is slightly Ground temporarily rises.Now, the plug members 35 positioned at the blocking position shown in Fig. 6 also rise, sometimes with the door of hall side The side portion of sill 32 is abutted.But, due to a pair top for the plug members 35 opposed with the side portion of the threshold 32 of hall side Corner implements chamfering 35b, therefore the abutting power of the part is weakened, be prevented from because of abutting and caused by damage.Also, by Supported in plug members 35 by leaf spring 52, therefore, in above-mentioned abutting, leaf spring 52 is also bent in above-below direction, therefore, by Its cushioning effect, because of abutting and caused by impact it is weakened, be thus also prevented from because of abutting and caused by damage.

On the other hand, if car door 25 carries out closing motion and is moved to predetermined position of closing the door, it is arranged at door-plate 25a The action component 42 of side leaves from the action pin 59 for constituting linkage 41.Therefore, linkage is put on via action pin 59 41 power is released from, for linkage 41, and by the tension force of back-moving spring 56, pivot fulcrum 45 turns clockwise towards diagram Dynamic, the plug members 35 supported by support 51 and by the support 51 are retracted from Fig. 5 state towards Fig. 4 state.Now, due to The bar 58 and 4 connecting rods 46,47,48,49 for constituting linkage 41 are tilted as previously described, therefore, and plug members 35 are being protected Moved under the attitude of water holding level state towards obliquely downward.Therefore, plug members 35 are moved from the blocking position shown in Fig. 6 towards diagram right Move to the bottom of the cage side threshold 31 shown in Fig. 7, Fig. 8 and keep being spaced for the lower surface of its upper surface and cage side threshold 31 Retreating position.

In above-mentioned avoidance operation from blocking position, even if being attached with foreign matter in the upper surface of plug members 35, Because plug members 35 keep the attitude of horizontality to be moved towards obliquely downward, and in its upper surface and the following table of cage side threshold 31 Face keeps the retreating position at interval to stop, and therefore, the movement of plug members 35 will not be hindered because of foreign matter, can reliably moved To retreating position.

So, plug members 35 by the linkage for bearing to act towards the locomotivity of the opening direction of car door and from Retreating position is moved to blocking position, and has in the closing motion of car door elastic force of the foreign all by back-moving spring And reliably moved from blocking position towards retreating position.For the movement, plug members 35 can be made by stop part 61 stifled Plug position and retreating position both sides correctly stop.Therefore, it is possible to reliably prevent that plug members from not stopping in normal position And surpassed distance and miscellaneous part collide and damage such situation.Even if also, assume occur surpassed distance, due to plug members 35 by Leaf spring 52 is supported, therefore, it is possible to be delayed by the flexure of leaf spring 52 to the impact produced by the collision with miscellaneous part Punching, is prevented from causing the damage of part.

In addition, in the case where leaf spring 52 is bent, junction surface that can be between support 51 produces gap, it is believed that if at this Dust etc. is accompanied in gap can not then reply original shape.Accordingly it is also possible in the portion that there is a possibility that to produce the gap Divide the protection for being previously applied ca(u)lk or cover etc. being set.

Also, leaf spring 52 has the flexure function towards above-below direction as previously described.Therefore, in order to more effectively produce The flexure in lower direction, can form at least one towards horizontal bending section, to produce longitudinal direction in the longitudinally intermediate portion of leaf spring 52 Elastic force.As the bending section, leaf spring 52 can be bent into section V-shaped as shown in Figure 10, or make it as shown in figure 11 Bend to semicircle.In addition it is also possible to make to be continuously formed above and below the bending of V-shaped multiple, or make semicircle up and down continuously Form bending that is multiple and forming S fonts.

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

In the above-described embodiment, linkage 41 is configured to as shown in FIG. 4 and 5 by back-moving spring (extension spring) 56 Tension force and support 51 is returned towards supporting member 44 layback all the time, but it is also possible to instead of the back-moving spring 56, be configured in supporting The operating spring 66 for producing repulsion is set between the right-hand member of part 44 and connecting rod 47, the direction towards Fig. 5 is assigned to support 51 all the time The power of stretching.I.e., support 51 and via leaf spring 52 be supported on plug members 35 on the support 51 via linkage 41 with Operating spring 66 links, and the locomotivity towards the blocking position shown in Fig. 5 and Fig. 6 is born all the time.

In this case, for linkage 41, when the end position of closing the door shown in the Figure 12 completely closed in car door 25 When putting, as shown in figure 13, action pin 59 engages with being arranged on the action component 72 of door-plate 25a sides.Therefore, linkage 41 is protected Hold the state in Fig. 4 of the repulsion of savings operating spring 66.I.e., plug members 35 are maintained at keeping out of the way shown in Fig. 7 and Fig. 8 Position.

On the other hand, if car door 25 carries out opening action, the enabling that door-plate 25a starts from Figure 12 end of closing the door is moved Make, then the action component 72 of the side of car door 25 from Figure 13 state towards diagram right movement, therefore, with the action component 72 it Between clamping force be released from.Therefore, each connecting rod 46,47,48,49 of linkage 41 is constituted by the repulsion of operating spring 66 Rotated in an anti-clockwise direction centered on pivot fulcrum 45 towards diagram.By the action of the linkage 41, support 51 and via plate The plug members 35 that spring 52 is supported on the support 51 stretch out from Fig. 4 state towards Fig. 5 state.I.e., plug members 35 are from Fig. 7 And the blocking position movement shown in the retreating position towards Fig. 6 shown in Fig. 8.
