The door 10 of the side for being equipped with light projector device 41 in pair of right and left door 10, is equipped with an end pieces.Door end
Part is set to the end of the door shield side of this 10.Door end pieces have light-blocking member 43 and transparent component 44.Light-blocking member 43 and thoroughly
The side by light projector device 41 of bright component 44 is adjacent.Conversely, transparent component 44 is with light-blocking member 43 by light receiving device
42 side is adjacent.Therefore, the configuration of transparent component 44 is in this 10 near the end of door shield side.Light-blocking member 43 is hidden by having
The material for keeping off the property of the light from light projector device 41 is constituted.Transparent component 44 passes through the light from light projector device by having
The material of property is constituted.
On the door end pieces with such light-blocking member 43 and transparent component 44, be formed with light limitation pin hole 45 and
Shade guidance slot 46.Shade guidance slot 46 is across the stop side of door 10 and the guiding groove of cage side setting.Light limit
The system through hole that pin hole 45 is for carrying out shrink beam to the light from light projector device 41.Light limitation pin hole 45 is formed in shading
The bottom of slot 46 is used in object guidance.
In addition, diameter is set as inspection in the case where light limitation is set as example circular situation with the shape of pin hole 45
Survey the width of the rope form barrier of object or less.In such manner, it is possible to which the outside light of the width more than shade is cut off, wherein should
Outside light more than the width of shade becomes the reason of being difficult to detect by thinner rope form shade.That is, being limited by light
Minimum limit needed for the light from light projector device 41 can be limited to detection rope form barrier with pin hole 45.
Light limitation pin hole 45 and the configuration of shade guidance slot 46 are in the position opposed with the front of light projector device 41.It changes
The extended line of Yan Zhi, light limitation pin hole 45 and the configuration of shade guidance slot 46 in the direction of illumination of the light of light projector device 41
On.Only by the light of light limitation pin hole 45 from the light that light projector device 41 irradiates, in the shade guidance inside of slot 46
By and to another party door 10 direction irradiation.From light projector device 41 irradiate light in, pass through light limitation pin hole 45
Light other than light is blocked by light-blocking member 43.
In this way, the light irradiated from light projector device 41 is by light limitation 45 shrink beam of pin hole.The configuration of light receiving device 42 is thrown in connection
On the extended line of the line of electro-optical device 41 and light limitation pin hole 45.Therefore, light receiving device 42 can be received irradiates from light projector device
And the light of light limitation pin hole 45 is passed through.
Shade guidance slot 46 is formed in transparent component 44.Also, light limitation is formed at least part of pin hole 45
In light-blocking member 43.Also, the shade guidance in transparent component 44 is also formed with through hole with the bottom of slot 46, the perforation
Hole is connected to the through hole of light-blocking member 43 and is formed the light limitation pin hole 45 an of entirety.
Fig. 4 is the figure of the door end pieces of the door 10 from 42 side of light receiving device equipped with light projector device 41.In door end pieces
The end face by door shield side of transparent component 44 be formed with shade guidance slot 46 above-mentioned.Shade guidance with slot 46 along
The thickness direction of door 10 is arranged from the cage side of door 10 across stop side.Light limitation pin hole 45, which configures to guide in shade, to be used
Center on the thickness direction of door 10 in the bottom of slot 46.
The width of the up and down direction of shade guidance slot 46 is in the thickness side for the door 10 for being configured with light limitation pin hole 45
It is most narrow at upward central portion.Also, the width of the up and down direction of shade guidance slot 46 is formed as with towards stop side
And cage side gradually broadens.
Consider in elevator door apparatus formed as described above with reference to Fig. 3 and Fig. 5, such as the rope forms shading such as lead of pet
Object is located at the case where between the door 10 of left and right from cage side across stop side.In addition, Fig. 5 is same as Fig. 4 from light receiving device 42
Side observation is equipped with the figure of the door end pieces of the door 10 of light projector device 41.
In this case, gating 10 is not in full close position and rope form shade is located at the shade 70 (A) of Fig. 3 and Fig. 5
Shown in position.At this point, the shade 70 in the position (A), which does not block from light projector device 41, passes through the injection of light limitation pin hole 45
Light.Therefore, light receiving device 42 receives the light from light projector device 41.Therefore, if light receiving device 42 receives light, between door
Shade test section 33 is judged as that between pair of right and left door 10, there is no shade i.e. barriers.
When door 10 is fully closed from the state, rope form shade 70 is sandwiched between the door 10 of left and right.Also, in carriage example
When people as risen or holding rope form shade 70 moves down the shade 70, rope form shade 70 is to be sandwiched in left and right
State between door 10 is mobile relative to the downward phase side of door 10.In this way, rope form shade 70 such as enters shown in (B) of Fig. 3 and Fig. 5
In shade guidance slot 46.
When state shown in rope form shade 70 is in (B) of the Fig. 3 and Fig. 5, being limited by light from light projector device 41
The light of 45 shrink beam of system pin hole is blocked by the shade 70.Therefore, light receiving device 42 is not received by from light projector device 41
Light.In this case, shade test section 33 not only detects the presence of the barrier between door 10 between door, and determines
And the barrier between this 10 is detected the presence of in rope form.Utilize door 10 that will enter and leave that is, being located at full close position in door 10
In the state that mouth is fully closed and in the case that light receiving device 42 is not received by the light from light projector device 41, as detection unit
Door between shade test section 33 detect that there are rope form barriers between pair of right and left door 10.
Here, as previously described, by make shade guidance slot 46 up and down direction width with towards stop side
And cage side and gradually broaden, even rope form shade 70 as depicted in figs. 3 and 5 from cage side cross over stop side tilted upward
In the case that ground sideling configures, also the shade 70 can be reliably directed to light limitation with slot 46 using shade guidance and used
Before pin hole 45.
In addition, and the width of the up and down direction by making shade guidance slot 46 is with towards stop side and cage side by
Gradual change is wide, even rope form shade 70 be embedded in shade guidance in slot 46 in the state of carriage it is further up or under
When drop, the shade 70 can also be made persistently to block light limitation pin hole 45 in a longer period of time.It therefore, can be more reliably
Detect rope form shade 70.
Alternatively, it is also possible to which multiple groups light projector device 41 and light receiving device 42 is arranged across the up and down direction of door 10.In this feelings
Under condition, it can also also set up multiple groups light limitation pin hole 45 according to light projector device 41 and the quantity of the group of light receiving device 42 and hide
Light object guidance slot 46.But light limitation pin hole 45 and the shade guidance quantity of slot 46 be no more than light projector device 41 and
The quantity of the group of light receiving device 42.
It is used it is further preferred, that collocation light limitation at least is respectively configured in the center of the up and down direction of door 10 and bottom
Pin hole 45 and shade the guidance light projector device 41 and light receiving device 42 of slot 46.In general, in thinner rope form barrier
When the case where user holds one head in the state of across cage side and stop side, it is believed that compare user in the position often held
Chest on the lower.And, it is also difficult to it is thinking rope form barrier to be located at user holds opposite one than utilizing
The high position in the position that person holds.In this way, the light projector dress for passing through will arrange in pairs or groups light limitation pin hole 45 and shade guidance slot 46
Set 41 and light receiving device 42 center and bottom in above-below direction is respectively configured, the case where carriage rises and the case where decline
Under both of these case, it is believed that rope form shade 70 can be guided to shade guidance slot 46 and detect the shade 70.
In the presence of shade test section 33 detects the rope form barrier between pair of right and left door 10 between door,
Rope form barrier detecting signal is exported from controlling device for doors 30 to elevator control gear 60.Elevator control gear 60 is being entered rope
When shape barrier detecting signal, if making carriage emergent stopping during carriage is traveling at.Then, elevator control gear 60 makes
Carriage is advanced, to return to the original floor just stopped before this.Also, keep carriage original what is just stopped before this
Floor stop, make door 10 open the door.
In addition, rope form shade 70 blocks the light from light projector device 41, light receiving device in door 10 not at shutdown position
In the case that 42 do not receive the light from light projector device 41, the shutdown of door 10 is prevented from, it is thus possible to avoid rope form shade
70 the case where being sandwiched between door 10.
In the following, referring to Fig. 6 flow chart illustrate elevator door apparatus formed as described above related rope form barrier inspection
The process of the movement of survey.
Firstly, in step sl, the fully closed judging part 32 of door determines according to the detecting signal from the fully closed detection device 50 of door
Whether door 10 is in full close position.When door 10 is in the case where full close position, S2 is entered step.
In step s 2, between door shade test section 33 according to light receiving device 42 by light state, be confirmed whether to detect
Shade between door 10.In the case where not detecting the shade gone out between 10, step S1 is returned to.On the other hand, exist
Detection is gone out in the case where the shade between 10, and door 10 is located at the shade that shutdown position and detecting is gone out between 10, thus
Shade test section 33 detects the presence of the shade of the rope form between door 10 between door.Also, in this case, into
Enter step S3.
In step s3, elevator control gear 60 makes carriage return to the original floor just stopped before this.Also,
In following step S4, after original floor is rested in carriage, elevator control gear 60 makes door 10 open the door.In this way, logical
It crosses and opens door 10 in original floor, the rope form barrier clamped by door 10 can be removed.In addition, in step s 4 with rope form
The related a series of movement of the detection of barrier terminates, and is restored to common operation control.
In addition, above explanation is related double-open type door 10.But door 10 is not limited to double-open type, is also possible to singly open
Formula.Door shield column is equipped in the case where door 10 is single open-type, the door shield column is when fully closed by the entrance of elevator using door 10
Adjacent mode configures with the door shield side of door 10.Also, light projector device 41 and door end pieces are set to door 10, and light receiving device 42 is set to
Door shield column.
In elevator door apparatus formed as described above, set in the end of the door shield side for the door 10 for being equipped with light projector device 41
Set an end pieces (light-blocking member 43 and transparent component 44), be formed in this end pieces: shade guidance slot 46 is crossed over
The stop side of door 10 and cage side setting；And the light limitation pin hole 45 as through hole, it is set to shade guidance and uses
The bottom of slot 46, light of the shrink beam from light projector device 41.
Also, light receiving device 42 is set as, and can be received and be irradiated from light projector device 41 and passed through light limitation pin hole 45
Light, when light receiving device 42 does not receive the feelings of the light from light projector device 41 in the state of using door 10 that entrance is fully closed
Under condition, shade test section 33 detects the presence of rope form barrier between door.
