The metalwork that plate spring part 30 is formed as an integral structure.Stationary plane 27 is fixed on the medial surface of cylindrical portion 32, as a result, as shown in figure 4,
Clamping part 28 is fixed on the upper end of cylindrical portion 32.At this point, plate spring part 30 is in the state in the outside for reaching cylindrical portion 32.In plate
Spine 31 is formed in spring portion 30.
Next, illustrating lower fixator 24 with reference to Fig. 5, Fig. 6.Fig. 5 is to decompose the inscape for showing lower fixator 24
Stereogram, Fig. 6 are the stereograms for showing lower fixator 24 being installed on the state of the lower end of a safety sensor 22.
Lower fixator 24 generally includes：Cylindrical portion 34 is embedded in the lower end of a safety sensor 22；And (second)
Elastic engaging portion 36 is sticked in the lower ora terminalis of inlet leg 20, to hold and fix the lower end of a safety sensor 22.
In the same manner as upper fixator 26, the cross section shape of cylindrical portion 34 and the sensor outer housing 22a of door safety sensor 22
Shape correspondingly forms as square tube shape, and can be embedded in sensor in a manner of being close to the lower end of sensor outer housing 22a
Shell 22a.Similarly, the slit 35 extended along its length is also formed in cylindrical portion 34, which is to avoid blocking
The gap of the light irradiated from light projector.
Elastic engaging portion 36 is the extension arm 38 of L-shaped shape, is rolled over from one end of the extension arm 38 with the upward lateral bending in right angle
Stationary plane 37 and the other end metal that vertically horizontal-extending plate spring part 39 is formed as an integral structure from extension arm 38
Part.Stationary plane 37 is fixed on the medial surface of cylindrical portion 34, as shown in fig. 6, extension arm 38 and plate spring part 39 are to outside cylindrical portion 34
Side is stretched out.Spine 40 is formed in plate spring part 39.
The door safety device of the boarding car entrance of present embodiment is constituted in the above-described manner, next, to it
Effect and effect illustrate.
In the following description, to not being to increase the elevator of setting newly but pacify door in the innovation of existing elevator
Full device is set to the case where entrance of boarding car 10 and illustrates.
Assuming that the existing elevator as renovation object does not have door safety device in the entrance of boarding car 10, therefore
In renovation in the newly-increased setting door safety device of car entrance.
In Fig. 1, the non-installation door safety sensor 22 originally on existing inlet leg 20.In the present embodiment, directly
Connecing, can by following step without being replaced, being processed to existing inlet leg 20 using existing inlet leg 20
Door safety sensor 22 is simply mounted on inlet leg 20, lower fixator 24, upper fixation have been used in following step
Device 26.
In the installation exercise of door safety sensor 22, lower fixator 24 is installed under a safety sensor 22 first
Upper fixator 26, is installed on the upper end of a safety sensor 22 by end later, to which door safety sensor 22 is fixed on entrance
Column 20.
Here, Fig. 7 is the shape for showing to be fixed on the lower end of door safety sensor 22 using lower fixator 24 inlet leg 20
The stereogram of state.Fig. 8 is the figure for the side for indicating to secure the lower fixator 24 in the state of the lower end of a safety sensor 22.
Fig. 9 is the figure for the section for showing the plate spring part 39 in Fig. 7.
Fixator 24 under the lower end installation of door safety sensor 22 before the mounting.In this case, only by tubular
Portion 34 is fitted to the lower end of a safety sensor 22.In lower fixator 24, extension arm 38 extends to the outer of cylindrical portion 34
Side, in the state that door safety sensor 22 is erected on sill 18, as shown in Figure 8 by the plate with 38 one of extension arm
Spring portion 39 is inserted into the slot 50 of sill 18.After such setting, a safety sensor 22 is made to be slid into along the extending direction of slot 50
Installation site.
As shown in figure 9, in the extension arm 38 of lower fixator 24, the spine 40 of plate spring part 39 can be with the side of inlet leg 20
41 lower end abuts, but when being slided in this state, plate spring part 39 can deform, to be pressed down to slot 50
In, later, position shown in Fig. 9 reverts to the shape of script.In this state, since the position of lower fixator 24 is protected
It holds, therefore the lower end of door safety sensor 22 is fixed on inlet leg 20.
Next, in Fig. 10, upper fixator 26 to be installed on to the upper end of safety sensor 22.In this case,
Upper end only by the way that cylindrical portion 32 to be fitted to safety sensor 22 from top, it will be able to simply install fixator 26.
While installing fixator 26, the plate spring part 30 of clamping part 28 engages the ora terminalis of inlet leg 20 simultaneously from top
It is clamped between cylindrical portion 32, therefore the position of the upper end of door safety sensor 22 is maintained.In this way, door passes safely
The upper end of sensor 22 can be also simply secured on inlet leg 20.
As described above, according to the present embodiment, by the way that upper fixator 26 and lower fixator 24 are installed on a safety sensing
Device 22, can simply installation door safety sensor 22, add without replacing existing inlet leg 20 or carrying out additional hole
Work.
In addition, being illustrated by taking the installation of the door safety sensor 22 in innovation as an example above, still, in elevator
It, certainly also can be with identical when installation door safety sensor on the new inlet leg in boarding car in newly-increased setting
The step of installed.
More than, enumerate door safety device of the preferred embodiment to the boarding car entrance involved by the utility model
It is illustrated, but these embodiments are to enumerate to come as example, it is no intended to limit the scope of the utility model.
Certainly, new device, method and the system described in specification can be implemented in various ways, further, can not take off
From carrying out various omissions, substitutions and changes in the range of the objective of the utility model.The range purport of claims and its equivalent
Embodiment in the range of covering the objective of the utility model or its improvement object.
