Then explain movable pillar 12 with respect to anchor post 11 at mechanism that above-below direction slides and downside arresting lever 14 with respect to movable pillar 12 in mechanism that above-below direction slides.Fig. 6 is the synoptic diagram that the inside of anchor post and the movable pillar of expression one side constitutes.In addition, Fig. 6 illustrates the state (movable fence 1 closing state) that movable pillar 12 and downside arresting lever 14 are positioned at the lower position.
And the inside of anchor post 11 and movable pillar 12 that constitutes the opposite side of movable fence 1 constitutes and also is formation shown in Figure 6.
Anchor post 11 support on the drive pulley 21,22 of configuration that is arranged above and below is provided with endless band 23.Movable pillar drive motor 52 is given driving force to the drive pulley that is positioned at downside 22.As stated, movable pillar drive motor 52 carries out drive controlling through movable pillar drive control part 51.
In addition, as shown in the figure, link the recess 24a that parts 24 form semi-spherical shape.In addition, be provided with when movable pillar 12 is positioned at the lower position, be embedded into the spherical block 25 among the recess 24a in the inside of anchor post 11.This block 25 by spring 26 to linking the parts 24 side application of forces.Also can spring 26 be replaced into other elastic bodys such as rubber.The axle of block 25 will be installed push link parts 24 sides to and constitute spring 26 here, and also can constitute the axle that block 25 has been installed pulled to and link parts 24 sides.
And then anchor post 11 has fixed pulley 27 in set inside.This fixed pulley 27 is installed on the top of the drive pulley 21 that supports the upside that is provided with endless band 23.Be wound with silk thread 28 on the fixed pulley 27.One end of silk thread 28 links to each other with binding parts 24.And the other end of silk thread 28 links to each other with weight 29.In movable pillar 12, the gravity that acts on weight 29 through fixed pulley 27 and silk thread 28 plays a role as the active force that makes movable pillar 12 to the direction of top slip.
Then explanation makes the formation that downside arresting lever 14 slides at above-below direction.Movable pillar 12 is being provided with endless band 33 along support on the drive pulley 31,32 of the configuration that is arranged above and below.Arresting lever drive motor 54 is given driving force to the drive pulley that is positioned at downside 32.As stated, arresting lever drive motor 54 is by arresting lever drive control part 53 drive controlling.
In addition, as shown in the figure, link the recess 34a that parts 34 are formed with semi-spherical shape.In addition, be provided with when downside arresting lever 14 is positioned at the lower position, be embedded into the spherical block 35 of recess 34a in the inside of movable pillar 12.This block 35 by spring 36 to linking the parts 34 side application of forces.Also can spring 36 be replaced into other elastic bodys such as rubber.Push link parts 34 sides to and constitute the axle that spring 36 will be equipped with block 35 here, also can constitute the axle that block 35 is installed pulled to and link parts 34 sides.
And then anchor post 12 has fixed pulley 37 in set inside.This fixed pulley 37 is installed on the top of the drive pulley 31 that supports the upside that is provided with endless band 33.Be wound with silk thread 38 on the fixed pulley 37.One end of silk thread 38 links to each other with binding parts 34.And the other end of silk thread 38 links to each other with constant weighted spring 39.The active force of constant weighted spring 39 tractive silk threads 38 plays a role as the active force that makes downside arresting lever 14 to the direction of top slip.
And can spring 26,36 be replaced into solenoid.Can also be replaced into weight with being arranged at movable pillar 12 inner constant weighted springs 39, yet therefore weight that in this case can the movable pillar 12 of corresponding increase can increase the burden when manually mentioning movable pillar 12.In other words, the burden of using constant weighted spring 39 when using weights to reduce manually to mention movable pillar 12, thereby belong to preferred.Can also constitute the weight 29 that is arranged at said fixing pillar 11 inside by constant weighted spring.
In addition, because upside arresting lever 13 is fixed on the framework of movable pillar 12, though therefore in Fig. 6, do not illustrate, that its height and support are provided with the drive pulley 31 of upside of endless band 33 is roughly the same.
When movable fence 1 was positioned at the lower position at movable pillar 12, block 25 was embedded among the recess 24a that links parts 24, has suppressed movable pillar 12 and has slided to the top.In addition, the regenerative braking of movable pillar drive motor 52 suppresses movable pillar 12 and slides to the top.As stated; Movable fence 1 obtains balance so that act on the mode that the gravity of weight 29 is slightly larger than the gravity that acts on movable pillar 12; And when movable pillar 12 is positioned at the lower position, to make this movable pillar 12 can not obtain balance to the mode of top slip naturally based on the fastening power of block 25 and the regenerative braking power of movable pillar drive motor 52.
In addition; For example ought grip upside arresting lever 13; When movable fence 1 was mentioned in the top, as shown in Figure 7, block 25 can be deviate from from the recess 24a that links parts 24 than the bigger power of the fastening power of block 25 and the regenerative braking power sum of movable pillar drive motor 52 in utilization.Block 25 can utilize the power bigger than the regenerative braking power of movable pillar drive motor 52 to mention movable pillar 12 to top (till upper limit position) after the recess 24a that links parts 24 deviates from.
