In addition, in lift facility, be provided with doorway device 7 at the elevator upper and lower opening of lift car 3 or each floor.Doorway device 7 has Room door 8 and threshold 14, and Room door 8 opens and closes along threshold 14.Only show the doorway device 7 that is arranged on elevator lobby in Fig. 1, and the structure of the doorway device 7 of lift car 3 is also roughly the same.
Fig. 2 is doorway device 7 structural representation on every side of observing from the elevator lobby of each floor.
Be provided with a guide rail 11 in top framework 10, Room door 8 is suspended on a guide rail 11 by door Suspension 9, and opens and closes under the driving of not shown door driving machine.In addition, the side end of the upper end of Room door 8 and left and right is hidden by doorframe 17.
Be provided with threshold 14 below Room door 8, this threshold 14 has the not shown threshold groove that extends along its length.
In addition, the upper component that Room door 8 is configured to the main body of this Room door 8 is connected with lower member and can be connected in the mode of above-below direction relative displacement, is provided with not shown guide boot in the bottom of this main body.Open and close along threshold 14 under the state of Room door 8 in guide boot is embedded in the threshold groove.In addition, when above-below direction was stressed, upper component and lower member made the reduced height of Room door 8 at the above-below direction relative displacement when Room door 8.
According to this structure of present embodiment, Room door 8 can not occur bending and deformation when occuring to disturb with threshold 14 easily.
Fig. 3 represents the constructional drawing of the structure example around Room door 8 and threshold 14.
In doorway device 7, Room door 8 adopts upper component 13 and lower member 18 structure connected to one another, by support 19, guide boot 15 is installed in the bottom of Room door 8.In the example of Fig. 3, upper component 13 forms the main body of Room door 8, and lower member 18 forms cover body.Support 19 is arranged on the bottom of the upper component 13 that forms Room door 8 main bodys, and runs through the lower member 18 that forms cover body.Said structure is an example only, and support 19 also can be arranged on the bottom of lower member 18.At this moment, the length setting of support 19 can be got very short.In addition, also can not use support 19 and guide boot 15 is directly installed on the bottom of lower member 18.In addition, be provided with elastic body (for example spring) 16 between upper component 13 and lower member 18, when being subject to the power of above-below direction, upper component 13 and lower member 18 utilize the elasticity of elastic body 16 to carry out relative displacement at above-below direction, make the reduced height of Room door 8.
Owing to having adopted structure shown in Figure 3, when the mainly earthquake in the above-below direction vibration has occured, ceiling and floor rocking in the situation that on approximating direction, displacement has occured because of building at building, due to the height of Room door 8 along with up-down vibration is dwindled, so can relax the interference between Room door 8 and threshold 14, can prevent that thus the situation that can't open and close from appearring in the Room door 8 because of distortion such as bendings.
In addition, as shown in Figure 3, owing to being provided with elastic body 16 between upper component 13 and lower member 18, so Room door 8 can be flexible when occuring to disturb with threshold 14, and can return to the original length after disturbing disappearance, thereby can return to rapidly state to be opened/closed.
In addition, as shown in Figure 3, due to the length that has lengthened the guide boot 15 that comprises support 19, and the degree of depth of having deepened the threshold groove, so Room door 8 is not easy to deviate from from the threshold groove more.The degree of depth that is embedded in the part in the threshold groove of guide boot 15 is preferably set to the degree of depth that can not deviate from because of the relative displacement that may occur between threshold 14 and Room door 8.For example the degree of depth that the threshold groove of the length of support 19 of guide boot 15 and threshold 14 is installed can be set as common 2 times of left and right.In addition, when occuring, earthquake etc. can avoid interference the interval of generation preferably reserving its size between the bottom of the threshold groove of guide boot 15 and threshold 14.
In addition, in this structure example, the connecting bridge of upper component 13 and lower member 18 is arranged on the bottom of Room door 8.For example the height setting with lower member 18 is several centimeters left and right.Thus, the connecting bridge of upper component 13 and lower member 18 can be too unobvious.
Fig. 4 represents the constructional drawing of another structure example around Room door 8 and threshold 14.
In the structure example of Fig. 4, different from the situation of Fig. 3, formed the cover body of Room door 8 by upper component 13, and formed the main body of Room door 8 by lower member 18.In addition, support 19 is arranged on the bottom of lower member 18.In addition, the same with the situation of Fig. 3, be provided with elastic body 16 between upper component 13 and lower member 18, when being subject to the power of above-below direction, upper component 13 and lower member 18 utilize the elasticity of elastic body 16 to carry out relative displacement at above-below direction, make the reduced height of Room door 8.
In this structure example, the connecting bridge of upper component 13 and lower member 18 is positioned at the top of Room door 8, is to be positioned at top framework 10 or doorframe 17 specifically.Therefore, connecting bridge is hidden in top framework 10 or doorframe 17, cannot see this connecting bridge from the outside.
In this structure example, guide boot 15 is arranged on lower member 18 by support 19, and along with the length of Room door 8 changes, guide boot 15 is in the above-below direction displacement.Therefore, guide boot 15 can not occur to disturb with the threshold trench bottom of threshold 14 and deform or damage etc.
In addition, in this structure example, due to guide boot 15 displacement along with the flexible of Room door 8, so compare with the situation of Fig. 3, can further dwindle the interval between the bottom of threshold groove of guide boot 15 and threshold 14.Thus, can will comprise that the length of guide boot 15 of support 19 and the degree of depth of threshold groove are set as roughly the same size.
Fig. 5 represents the constructional drawing of the another structure example around Room door 8 and threshold 14.
The structure example of Fig. 5 is the same with the structure example of Fig. 4, is also to be formed the cover body of Room door 8 by upper component 13, and is formed the main body of Room door 8 by lower member 18.
In the structure example of Fig. 5, do not form elastic body between upper component 13 and lower member 18, and the structure example of the method for attachment between upper component 13 and lower member 18 and Fig. 4 is different.
Fig. 6 is the instruction diagram of the method for attachment in the structure example of Fig. 5.
Can know from Fig. 5 and Fig. 6, be formed with the slotted hole 21 that extends along the vertical direction on upper component 13, bolt 22 is screwed into lower member 18 by this slotted hole 21, thus upper component 13 is fixed on lower member 18.At this moment, during power when Room door 8 more than above-below direction has been subject to a certain degree, bolt 22 is in the interior movement of slotted hole 21, and upper component 13 and lower member 18 are carried out relative displacement, make the reduced height of Room door 8.
According to this structure, because the height of Room door 8 dwindles when occuring to disturb with threshold 14, so Room door 8 can not bend easily and be out of shape because occuring to disturb with threshold 14.When adopting this structure, can simplified structure and reduce costs, but due to elastic body 16 not being set, so the length of Room door 8 can not return to the original length.But, owing to not bending and being out of shape, so re-start the location by the relative position to upper component 13 and lower member 18, can return to easily original state.
The embodiment of the invention described above is for the example that the present invention will be described, and scope of the present invention is not subject to the restriction of above-mentioned various embodiments.In the situation that do not break away from aim of the present invention, can adopt various other modes to implement the present invention.
