It is fixed on scaffold 31.
As shown in Figures 3 to 5, in threshold 15B bottom formed with the groove portion 35 for guiding door 15A.Groove portion 35 is along door
Sill 15B long side direction is configured to linear.Threshold 15B is the door of the flat type formed in a manner of groove portion 35 is open downwards
Sill.
Door 15A has：It is sticked in groove portion 35 and the guide portion (guide block) 36 for guiding this 15A；Guided for supporting
The support (bracket) 37 in portion 36；It is used to prevent screening cigarette part 38 of the cigarette by threshold 15B when a fire；Hidden for supporting
The supporting member 39 of cigarette part 38.As shown in figure 4, the component Configuration being made up of guide portion 36 and support 37 is under door 15A
Portion and the both ends for being arranged respectively at the width of a 15A (at two).In addition, screening cigarette part 38 and supporting member 39 are located at
The central portion of door 15A width, that is, be located between said modules.
Guide portion 36 is the elastomer formed by the synthetic resin material such as rubber.Plate of the guide portion 36 as strip
Part is formed.
Support 37 is metal system, is configured to the tabular of strip.Support 37 is for example formed as by punch forming
Provide shape.As shown in figure 5, the one end of support 37 is fixed on the lower side of a 15A via installing component 40.Supporting
The other end in portion 37 is integrally formed with guide portion 36.In addition, the length L1 of the vertical of support 37 is than door 15A and door
Sill 15B clearance C length.
It is the elastomer formed by the synthetic resin material such as rubber to hide cigarette part 38.Hiding cigarette part 38 has：With door
The contact site 41 of the part contact of the inner side of sill 15B groove portion 35；Installation portion 42 on supporting member 39.
Contact site 41 is configured to tabular, is determined in a manner of being contacted by the part of the inner side with groove portion 35 and elastic deformation occurring
Position.It is further preferred that contact site 41 and the partial face contact of the inner side of groove portion 35.As shown in fig. 6, contact site 41 is with upward
Prominent mode configures.
As shown in fig. 6, installation portion 42 is formed as the jut prominent to the direction opposite with contact site 41.Installation portion 42
It is bigger than base portion to be configured to leading section.
As shown in fig. 6, supporting member 39 is for example configured to the tabular of strip by extrusion molding.Supporting member 39
One end is fixed on the lower side of a 15A.In the other end of supporting member 39 formed with the installation portion for hiding cigarette part 38
The mounting recess 43 of 42 installations.The leading section for hiding the installation portion 42 in cigarette part 38 is embedded with mounting recess 43.Support
The length L2 of the vertical of part 39 is longer than door 15A and threshold 15B clearance C.
As shown in Fig. 2, Fig. 5 and Fig. 6, guard block 32 is supported in scaffold 31 via frame support bracket 44.Protection portion
Part 32 is fixed on frame support bracket 44 by screwed part 45.Guard block 32 has：Guarantor for the toe of Sustainable use person
Shield portion 46, the fixed part 47 being fixed on frame support bracket 44.
Protection portion 46 is configured to jut prominent upward.Protection portion 46 has the opposite face opposed with threshold 15B
46a.As shown in Figure 5, Figure 6, the opposite face 46a of protection portion 46 is formed as relative to vertical with the inclined inclination of predetermined angular
Face.
Fixed part 47 is configured to tabular, and with the inserting hole 48 that can insert screwed part 45.As shown in Figure 5, Figure 6,
The inserting hole 48 turns into the elongated hole grown in the vertical direction.Thus, guard block 32 can be in the scope of the length of inserting hole 48
The interior position to above-below direction is adjusted.Frame support bracket 44 is formed with the screwed hole 44a being screwed for screwed part 45.
According to side door opening and closing device 15 at the boarding of elevator discussed above, make to form the groove in threshold 15B bottom
Portion 35 is open downwards, screening cigarette part 38 is close to the part of the inner side of the groove portion 35, and guide portion 36 is embedded in into groove portion
35, thereby, it is possible to prevent cigarette from passing through via groove portion 35 in the inward-outward direction of door.Therefore, side door is opened and closed at boarding
Device 15 also can reliably carry out screening cigarette using in the case of flat threshold.
In addition, in the case where making screening cigarette part 38 be close to threshold 15B, it is also contemplated that make contact site 41 and threshold 15B's
Upper surface simultaneously carries out screening cigarette.But in this case, hiding cigarette part 38 can produce in threshold 15B upper surface slide
Abrasion.Thus, the vestige of the abrasion of cigarette part 38 can be hidden in threshold 15B upper surface residual, so as to cause outward appearance not beautiful.Moreover,
Because user, luggage etc. are by the way that threshold 15B upper surface is always worn away.If cigarette part 38 is hidden the threshold 15B's worn away
Upper surface slide, the then abrasion for hiding cigarette part 38 are accelerated, and hide the lost of life of cigarette part 38.
And in the present invention, due to make screening cigarette part 38 be close to groove portion 35 inner side part, so, hide cigarette part 38
Wear pattern will not expose, wherein the groove portion 35 is formed in threshold 15B bottom.It is additionally, since and hides cigarette part 38 and groove
The part contact of the inner side in portion 35, and the part of the inner side of groove portion 35 will not produce the abrasion as threshold 15B upper surface,
Thus it is possible to prevent that hide cigarette part 38 deteriorates in early days, so that it is guaranteed that its fully long life-span.
It is made up of, is close to by elastic deformation come the part of the inner side with groove portion 35, institute elastomer in addition, hiding cigarette part 38
Can more reliably enter threshold trip 15B screening cigarette.The supporting member 39 supported to hiding cigarette part 38 is additionally, since to consolidate
The bottom of door is scheduled on, so, the movement of a 15A can be followed by hiding cigarette part 38, and total energy maintains to hide cigarette.
In addition, the elevator door opening-closing device of the present invention is not limited to the structure of above-mentioned embodiment.In addition, the elevator of the present invention
Device for opening/closing door is also not necessarily limited to above-mentioned action effect.The elevator door opening-closing device of the present invention can not depart from the master of the present invention
Various changes are carried out in the range of purport.
For example, screening cigarette part 38 is not limited to the example shown in Fig. 6.For example, as shown in fig. 7, screening cigarette part 38 can not also
Using supporting member 39, and it is supported on the support 37 supported to guide portion 36.By in such manner, it is possible to reduce boarding
Locate the number of parts of side door opening and closing device 15, cost degradation can be realized.
In addition, as shown in figure 8, it can also be with being configured to linear contact site 41 and with straight line to hide cigarette part 38
The structure for the installation portion 42 that shape is formed.In this case, contact site 41 is configured to tilt with predetermined angular relative to installation portion 42.Separately
Outside, as shown in figure 9, the contact site 41 for hiding cigarette part 38 msy be also constructed to the rounded component of section view.In addition, such as Figure 10 institutes
Show, the contact site 41 for hiding cigarette part 38 can also be configured to tubulose.
In the above-described embodiment, the example that the present invention is applied to side door opening and closing device 15 at boarding is shown, but
The present invention can also be applied to cage side device for opening/closing door 14.
In above-mentioned embodiment, exemplified with the device for opening/closing door 14,15 of midsplit type, but this is not limited to, additionally it is possible to will
The present invention is applied to laterally opened device for opening/closing door.
