In addition, its cross section is the shape of lengthwise, in the opposed portion opposed with the diagram right flank of the sill 32 of stop side Place is formed with recess 35a.Recess 35a be in order to avoid being located at the sill 32 of stop side diagram right flank on screw 36a Head and set.Screw 36a is used to install the plate 36 for being separated lower interlayer space.And then, to the plugging part 35 Upper corner implement chamfering 35b.

In addition, the plugging part 35 be metal system or it is resinous which kind of can, but if consider processability and and its Resiliency of his part etc., then preferably with resin piece.

The plugging part 35 can the block-up position for blocking the gap of sill 31,32 represented by Fig. 6 with by Fig. 7 and Slide mobile between the retreating position of what Fig. 8 was represented the keep out of the way bottom of the sill 31 of cage side and constitute that (Fig. 8 is in order that moving back The figure that the state for the plugging part 35 kept away at position is easily observed and removes the part of a part from Fig. 7 and represent).Also, By drive mechanism 41 described later, with the on-off action of car door 25 by sliding between above-mentioned block-up position and retreating position Dynamic driving.

Plugging part 35 is arranged on located at driving via the elastomeric element (being illustrated below as leaf spring) 52 of leaf-spring-like On the bracket 51 of the side of mechanism 41.Therefore, plugging part 35 by leaf spring 52 in the sill 31 and the sill of stop side of cage side Swingably it is supported by 32 septal direction (can also be relative to the fore-and-aft direction for sliding moving direction).The bracket 51 and Leaf spring 52 is also divided with the identical part of plugging part 35, and the divided corresponding part of plugging part 35 is supported respectively.

Drive mechanism 41 is configured to, as shown in Figure 3 can be with the side of car door 25 with the on-off action of car door 25 Action component 42 engage.Also, it is envelope by the force transformation being subject to from action component 42 by the engaging with the action component 42 The slip moving direction of stifled part 35, plugging part 35 is driven on moving direction is slided.

In this embodiment, drive mechanism 41 as shown in Figure 4, Figure 5, with 4 connecting rods 46,47,48,49 and via The bracket 51 that connection shaft 50 rotationally links with each one end of these connecting rods.4 connecting rods 46,47,48,49 are via the quilt of pivot 45 It is rotatably supported on the supporting member 44 of the side of car 4.

The connecting rod 47,48 of inner side in this 4 connecting rods links driving and used, and their other end connects via connection shaft 54 Knot is on connecting rod 55.Connecting rod 47,48 and connecting rod 55 on the inside of this are the bracket 51 and plate for making plugging part 35 subsidiary with it What the part of quilt of spring 52 or so segmentation was interlocked, these divided parts are integrally acted.In the diagram right-hand member of the connecting rod 55 Opened between supporting member 44 and be provided with extension spring 56, applying for drive mechanism 41 makes bracket 51 parallel to the side of supporting member 44 The power in mobile direction.

On the pivot 45 of connecting rod 46 for constituting the drive mechanism 41, the base end part of lever 58 is integratedly installed.At this The leading section of lever 58 is equipped with action pin 59.The upper side of the action pin 59 is as shown in figure 3, can be with being integrally provided at sedan-chair The action component 42 of the door-plate 25a sides of railway carriage or compartment door 25 engages and configured.That is, action pin 59 passes through the opening action of car door 25 to regulation Open position, so as to abut engaging with action component 42, make lever 58 and the pivot 45 integral with it to diagram counterclockwise Rotate.

By the rotation, other connecting rods 47,48,49 linked with the connecting rod 46 of the one of pivot 45 and via bracket 51 Also resist the tension force of extension spring 56 and rotated in an anti-clockwise direction to diagram.By the action of the drive mechanism 41, bracket 51 and Via leaf spring 52 support retreating position that plugging part 35 at an upper portion thereof represented from Fig. 4 and Fig. 7, Fig. 8 in Fig. 5 and The block-up position represented in Fig. 6 is sent out.

Here, above-mentioned extension spring 56 finally links via drive mechanism 41 and the grade of bracket 51 with plugging part 35.The drawing Stretch spring 56 and apply send plugging part 35 to the retreating position represented in Fig. 4 and Fig. 7, Fig. 8 back to via drive mechanism 41 The power in direction.Thus, the extension spring 56 as plugging part 35 is sent back to retreating position return spring function (with It is referred to as return spring 56 down).

So, drive mechanism 41 is by the opening action of car door 25 to defined open position, and its action pin 59 is as in figure 3 Represent that action component 42 like that with the side of car door 25 engages, by the evolution to car door 25 to locomotivity, make in moving back Keep away the spring force of the resistance return spring 56 of plugging part 35 of position and be slidably moved to block-up position.

For the above-mentioned slip movement of plugging part 35, as shown in Figure 6 to 8, being set on supporting member 44 stops it Only in the block 61 of block-up position and retreating position.The part of block 61 is taken out and represented by Fig. 9.The block 61, which has, to be fixedly installed U-shaped member on supporting member 44, the bolster 62 provided with rubber etc. on its two medial surface, be configured between them from The abutment 63 of the extended section L-shaped of the bracket 51 of the side of plugging part 35.

By the structure, the abutment 63 being extended from bracket 51 is connected to two inner sides of the U-shaped member of block 61 On face, so as to make plugging part 35 slip move correctly stop at block-up position and retreating position.In addition, rubber etc. Bolster 62 can also be located in one party of block 61 and abutment 63 or both.

Constitute in the pivot 45 of drive mechanism 41 with configuring the axle in the one of lever 58 of Fig. 2, Fig. 3 right-hand member, be logical Cross the rotary shaft that the action pin 59 erected on lever 58 abuts engaging with the action component 42 of the side of car door 25 and rotated.At this In rotary shaft, torque spring 65 is provided with like that as shown in Figure 6 to 8, apply the rotation that resistance comes with the snap belt of action component 42 Turn the revolving force in direction.

By the structure, in the state of action pin 59 does not engage with action component 42, action pin can be made always to return To correct position.

In said structure, when state of the car door 25 for closing, the operating member of the side of car door 25 represented in figure 3 Part 42 does not abut engaging with the action pin 59 of the side of drive mechanism 41, and drive mechanism 41 is not made by from the side of car door 25 Firmly.Therefore, plugging part 35 and support the tension force of the return spring 56 that its bracket 51 is represented in Fig. 4 and be withdrawn into supporting The side of part 44, plugging part 35 in Fig. 7 and Fig. 8 as representing, the retreating position of the bottom in cage side sill 31.

If the flat bed of car 4 is in stop, car door 25 starts work and moved to defined open position, then is located at door-plate 25a The action component 42 of side abuts engaging with constituting the action pin 59 of drive mechanism 41, operation force is opened by door-plate 25a, with pivot The lever 58 provided with action pin 59 is set to be rotated in an anti-clockwise direction to diagram centered on 45.

By the action, the tension force of the resistance return spring 56 of drive mechanism 41 to equidirectional rotation, by bracket 51 and branch Hold and sent out in plugging part 35 thereon from Fig. 4 state to Fig. 5 state.Thus, the table from Fig. 7, Fig. 8 of plugging part 35 The retreating position of the bottom of the cage side sill 31 shown is slided to diagram left and moved, and reaches the closure represented in Fig. 6, Fig. 9 Position., will also, the leading section (diagram left part) of the plugging part 35 is abutted with the diagram right flank of the sill 32 of stop side Gap closure between sill 31,32.

Here, the interval in the gap between sill 31,32 is that gap size is not certain value as described above, because of the peace of each layer If error and it is different.In addition, by the railway carriage or compartment downward shift rocked before and after the guiding device of railway carriage or compartment or during boarding, size also changes.

In embodiment of the present utility model, plugging part 35 is arranged on bracket 51 via leaf spring 52, can be in cunning Constitute to the swing of dynamic moving direction.That is, plugging part 35 can be in prominent position (block-up position) swing.This Outside, it is configured to, is exerted a force by leaf spring 52 to stop side (diagram left), to railway carriage or compartment direction if is pushed to railway carriage or compartment direction (diagram right) Pull in (Japanese：Yin き Write body), returned to original block-up position if the power pushed is released from.

By the construction, in running clearance than in the case of generally narrow, being pushed back to cage side (diagram right), wider In the case of can be prominent to block-up position, so the higher sealed condition of leak tightness can be obtained.

So, plugging part 35 blocks the gap between sill 31,32 when in block-up position, so small article will not Drop in well, can easily reclaim from the gap.Further, since the upper surface of plugging part 35 be located at than sill 31, 32 upper surface on the lower, so the load of the object on sill 31,32 will not be applied on plugging part 35, Neng Goufang The only damage of the support of the plugging part 35 caused by load applies.

Under the sealed condition in the gap brought by the plugging part 35, if the load of car 4 significantly changes, have The temporary situation about rising slightly of car 4.Even if occurring the temporary rising of such car 4, due to plugging part 35 Upper corner implements chamfering 35b, and plugging part 35 is supported by leaf spring 52, so the problem of damage etc. does not occur yet.

For example, being multiplied with full state in the case that the passenger in car 4 once gets off etc., car 4 is despite slightly But temporarily rise.Now, the plugging part 35 in block-up position represented in figure 6 also rises, the ground with stop side The bottom side portion of bank 32 is abutted.But, due to a pair plugging part 35 opposed with the bottom side portion of the sill 32 of stop side Upper corner implement chamfering 35b, so the abutting power of the part is weakened, be prevented from the damage caused by abutting.This Outside, because plugging part 35 is supported by leaf spring 52, so in above-mentioned abutting, because leaf spring 52 is also bent in the vertical direction, So by its cushioning effect, the impact brought by abutting is weakened, therefore is also prevented from the damage caused by abutting.

On the other hand, if car door 25 closes action, be moved to as defined in close a position, then be located at the dynamic of door-plate 25a sides Make part 42 to leave from the action pin 59 for constituting drive mechanism 41.Therefore, acted on via action pin 59 in drive mechanism 41 Power be released from, drive mechanism 41 by the tension force of return spring 56, pivot 45 to diagram rotationally clockwise, by bracket 51 And the plugging part 35 being supported on thereon is retracted from Fig. 5 state to Fig. 4 state.Thus, plugging part 35 is from table in figure 6 Position is kept out of the way in the bottom of cage side sill 31 that the block-up position shown is slidably moved to represent in Fig. 7, Fig. 8 to diagram right Put.

So, plugging part 35 by by the evolution to car door to locomotivity and the linkage that acts, from moving back Keep away position and be slidably moved to block-up position, car door when closing action by the spring force of return spring from block-up position to keeping out of the way Slide movement in position.The slip, which is moved through block 61, can make plugging part 35 correctly stop at block-up position and keep out of the way position Put at both.Therefore, it is possible to reliably prevent plugging part from not stopping at normal position and overrun and and other parts Collide and damage such situation.Even if in addition, there occurs overrun, because plugging part 35 is supported by leaf spring 52, so Also can by the flexure of leaf spring 52 by because the collision belt with other parts come damping of shocks, be prevented from causing the damage of part Wound.

In addition, in the case where leaf spring 52 is bent, having and the situation in gap occurring with the junction surface of bracket 51, if at this Dust etc. is clipped in gap, then it is considered that original shape can not be returned to.It is preferable that being likely to occur this Implement the protection of ca(u)lk, the setting of cover etc. in advance in the part of gap.

In addition, leaf spring 52 has the function of flexure vertically as described above.Therefore, in order to more effectively produce The flexure of above-below direction, can also at least form 1 to horizontal bending section in the longitudinally intermediate portion of leaf spring 52, produce longitudinal direction Spring force.As the bending section, leaf spring 52 can also be bent to section V-shaped as shown in Figure 10, or as shown in figure 11 It is bent into semicircle like that.And then, the bending of V-shaped can also be made continuous multiple up and down, or make semicircle continuous multiple up and down and Form the bending of S fonts.

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

In the above-described embodiment, drive mechanism 41 is configured to as shown in Figures 4 and 5, passes through return spring (stretching Spring) 56 tension force always returns bracket 51 to supporting member 44 layback, but it is also possible to it is configured to, instead of the return spring 56 The operating spring 66 that repulsive force is produced between the right-hand member of supporting member 44 and connecting rod 47 is arranged on, is always applied bracket 51 to figure The power that 5 direction is sent out.That is, bracket 51 and plugging part 35 on the bracket 51 is supported on via drive mechanism via leaf spring 52 41 link with operating spring 66, are always subjected to the locomotivity to the block-up position represented in Fig. 5 and Fig. 6.

In the case, drive mechanism 41 when car door 25 be in close completely represent in fig. 12 close an end position When, as shown in figure 13, action pin 59 engages with being located at the action component 72 of door-plate 25a sides.Therefore, drive mechanism 41 is retained as The state for Fig. 6 that the repulsive force of operating spring 66 is put aside.That is, plugging part 35 was maintained at by keeping out of the way that Fig. 7 and Fig. 8 are represented Position.

In contrast, if car door 25 starts work, door-plate 25a starts to close a door opening action at end from Figure 12, then sedan-chair The action component 72 of railway carriage or compartment 25 sides of door is moved from Figure 13 state to diagram right, so being solved with the clamping force of the action component 72 Remove.Therefore, each connecting rod 46,47,48,49 of drive mechanism 41 is constituted under the repulsive force effect of operating spring 66, with pivot 45 Centered on rotated in an anti-clockwise direction to diagram.By the action of the drive mechanism 41, bracket 51 and this is supported on via leaf spring 52 Plugging part 35 on bracket 51 is sent out by the state from Fig. 4 to Fig. 5 state.That is, plugging part 35 is from Fig. 7 and Fig. 8 The retreating position of expression is slided to the block-up position represented in figure 6 and moved.

On the other hand, in the case where car door 25 is from full-gear closing, closed by door-plate 25a attached to an end is closed Closely, action pin 59 of the action component 72 as shown in Figure 13 with the side of drive mechanism 41 engages.Therefore, the thick stick with action pin 59 Bar 58 is driven clockwise by the door-plate 25a power for closing direction to diagram.That is, the side of closing that drive mechanism 41 passes through door-plate 25a To power, the plugging part 35 being supported on by bracket 51 and via leaf spring 52 on the bracket 51 returns to Fig. 4 shape from Fig. 5 state State.That is, plugging part 35 slides movement from the block-up position represented in figure 6 to the retreating position represented in Fig. 7 and Fig. 8.

So, drive mechanism 41 by since car door 25 close Men Duanqi door opening action, with action component 72 Engaging is released from, so allowing that the slip to block-up position of the plugging part 35 brought from the repulsive force of operating spring 66 is moved It is dynamic.In addition, as car door 25 is to a movement at end is closed, engaging with the action component 72 of the side of car door 25, by car door 25 locomotivity, makes the plugging part 35 in block-up position be slidably moved to retreating position.

That is, if car door 25 is started to open at, plugging part 35 immediately moves to block-up position.Closed in car door 25 In the case of, before full-shut position to be turned into, plugging part 35 is moved to retreating position from block-up position.Therefore, even in Car door 25 is opened or closed passenger or goods in action way and comes in and goes out, because plugging part 35 is by the gap closure between sill 31,32 State, so also can reliably prevent that small article from dropping such situation from gap.

In addition, the snap portions of the action component 42,72 with the side of car door 25 of drive mechanism 41, i.e. setting action pin 59 Position be the gateway 24 of car 4 being opened and closed by car door 25 frontal width outside.

In the above-described embodiment, drive mechanism 41 is all for the locomotivity of plugging part 35 by the opening and closing force transformation of door The structure mechanically driven, but drive mechanism of the present utility model is not limited to such mechanical drive mechanism.For example, Can also be that electrically detection door has reached defined open position or closed position and made the actuator action of motor etc., makes closure part The such drive mechanism of part movement.

In addition, in the above-described embodiment, drive mechanism 41 all makes plugging part 35 be slidably moved to envelope from retreating position Stifled position.But, problem of the present utility model is：By will be carried out to the gap of the sill of stop side and the sill of cage side The plugging part of closure is swingably supported in the septal direction in gap, even if gap size has variation, also by appropriate The plugging part of size shape is reliably blocked.This is for example also applicable to while making the retreating position of plugging part from below Rise and also move it and carried out in the structure of closure action in the horizontal on one side.Thus, drive mechanism can be not only to make envelope Stifled part slides the composition of movement or will move up and down the mobile combination with transverse direction and mobile such structure.

Some embodiments of the present utility model are illustrated, but these embodiments are pointed out as an example, are not meant to Limit interest field.These new embodiments can be implemented with other various forms, not depart from the scope of purport It is interior to carry out various omissions, replace, change.These embodiments and its deformation are included in interest field and purport, and Included in the utility model described in claims and its scope of equal value.
