Embodiment 1 of the present invention will be described with reference to FIGS.
It will be explained with reference to. 1 is a diagram showing a cross section of the overall configuration of Embodiment 1 of the present invention. FIG. 2 is an enlarged cross-sectional view of portion A of FIG. FIG. 3 is a diagram showing a front side of the car according to the first embodiment. FIG. 4 is a diagram showing the front of the landing side of the first embodiment. FIG. 5 is a block diagram showing the system configuration of the first embodiment of the present invention. FIG. 6 and FIG. 7 are views showing the cross-sectional structure of the first embodiment when there is a landing shift.

In FIG. 1, the user 1 to the landing threshold 8 are the same as those in the conventional example, and the description thereof will be omitted. In FIGS. 1 and 2, reference numeral 9 is a photoelectric device for detecting a floor slip, and 10 is a reflecting mirror attached to the lower part of the hall sill 8 and made of, for example, mirror surface stainless. Further, 11 is an illuminating device attached to the lower portion of the car sill 5. The photoelectric device 9 is attached to the illumination device 11 at approximately the center in the vertical direction (which will be described later with reference to FIG. 3). In addition, B shows an allowable range of landing error.

In FIG. 2, the light beam 12 emitted from the optoelectronic device 9 is reflected by the reflecting mirror 10, and the reflected light beam 1
2 hits the light receiving portion (not shown) of the photoelectric device 9, and it is determined that the photoelectric device 9 is at the position where it is reflected by the reflecting mirror 10.

FIG. 3 is a front view of the car room seen from the hall side. The illumination device 11 under the car sill 5 is attached only to the width of the portion where the car door 4 is opened and closed, and the photoelectric device 9 is attached to the center thereof. Has been. Further, FIG. 4 is a front view of the hall viewed from the side of the car, and the reflector 10 at the bottom of the hall sill 8 is also attached only to the width at which the hall door 7 opens and closes.

In FIG. 5, 13 is various elevator signals transmitted from an elevator control panel (not shown), 14 is a control unit such as a microcomputer, 15 is a photoelectric device light emission control unit, and 16 is a photoelectric device light reception processing unit. , 17 are illumination control units. The control unit 14 to the lighting control unit 17 are provided in the cab room 2. In addition, the illuminating means according to claim 1 is composed of the reflecting mirror 10, the illuminating device 11, the control section 14, and the illumination control section 17 in the first embodiment, and the floor shift detecting means according to the second aspect is in the first embodiment. The photoelectric device 9, the reflecting mirror 10, the control unit 14, the photoelectric device light emission control unit 15, and the photoelectric device light reception processing unit 16 are configured.

In FIG. 5, when the elevator arrives at the destination floor, an elevator signal 1 is sent from the elevator control panel.
As 3, the stop signal enters the control unit 14. The control unit 14
The photoelectric device light emission control unit 15 is instructed to emit light from the photoelectric device 9. If the landing error is within the landing error allowable range B in FIG. 2, the light beam 12 is reflected by the reflecting mirror 10 and returns to the light receiving unit (not shown) of the photoelectric device 9. The signal generated by the light receiving unit enters the control unit 14 through the photoelectric device light receiving processing unit 16. This signal is a signal that the floor slip is small, and even if the door open signal is received as the elevator signal 13, the illumination control unit 17 is not instructed to turn on the illumination.

As shown in FIGS. 6 and 7, the function when a step is formed between the hall sill 8 and the car sill 5 for some reason will be described.

A stop signal enters the control unit 14 as the elevator signal 13, and the control unit 14 controls the photoelectric device light emission control unit 15.
To instruct the photoelectric device 9 to emit light. At this time, for example, as shown in FIG. 6, when the car sill 5 stops above the landing sill 8, even if the photoelectric device 9 emits the light beam 12 toward the reflecting mirror 10, the landing error allowable range is reached. If it is shifted from B, the light beam 12 does not hit the reflecting mirror 10 and the emitted light beam 1
2 does not return to the photoelectric device 9. Therefore, the photoelectric device light reception processing unit 16 does not output a signal to the control unit 14.

When the door open signal is received as the elevator signal 13, if there is no signal from the photoelectric device light reception processing unit 16, the control unit 14 issues an illumination lighting command to the illumination control unit 17, and the illumination device 11 is illuminated.

In the example of FIG. 6, the light 18 of the illuminating device 11 flows to the hall side, so that the user 6 mainly from the hall can be informed of the danger and a disaster due to tripping can be prevented.

The example of FIG. 7 has the same function as that of FIG. 6, but
The light of the illuminating device 11 is reflected by the reflecting mirror 10 and reflected light 19
As a result, it is possible to inform the user 1 mainly from the car room 2 of the danger and prevent a disaster due to a trip or the like.

Example 2. A second embodiment of the present invention will be described with reference to FIGS. 8 and 9 show
It is a figure which shows the front of a car room and a hall when this Example 2 is seen from a hall and a car room, respectively.

The difference from the first embodiment is that, in the first embodiment, the photoelectric device 9 is located at the center of the illumination device 11 and can also serve as the reflecting mirror 10, so that only one reflecting mirror is required.

In the second embodiment, as shown in FIG. 8, the photoelectric device 9 is separated from the illumination device 11. As a result, the reflection mirror 20 for a photoelectric device, which is made of mirror-finished stainless steel or the like, is required. However, the provision of this has the following advantages. The other configurations are the same as those in the first embodiment.

In the first embodiment, when the illumination device 11 is turned on,
Even if the elevator automatically adjusts the floor, the reflector 10
Therefore, it is impossible to determine whether the light from the illumination device 11 hits the light receiving portion of the photoelectric device 9 and the floor slip is corrected.

In the second embodiment, since the light beam 12 of the photoelectric device 9 and the light 18 of the illumination device 11 can be separated, the elevator automatically performs floor alignment so that the light beam 12 falls within the allowable range of landing error. In this case, the light beam 12 is reflected by the photoelectric device reflection mirror 20 and returns to the light receiving portion of the photoelectric device 9. The photoelectric device light reception processing unit 16 sends a signal to the control unit 14 according to a signal from the photoelectric device 9. The control unit 14 determines that the floor slip has been corrected, and issues a turn-off command to the illumination control unit 17 to turn off the illumination of the illumination device 11. As a result, the lighting is turned on only when there is a floor slip, and the anxiety given to the users 1 and 6 can be minimized.

In the first embodiment, the allowable range B for landing error is determined by the width of the reflecting mirror 10. However, the dimensional change of the reflecting mirror 10 is limited due to illumination. However, in the second embodiment, the allowable range of landing error can be determined by the reflecting mirror 20 for the photoelectric device, so that the adjustment can be made according to the model and the sensitivity of the customer.

Example 3. A third embodiment of the present invention will be described with reference to FIG. FIG. 10 is an enlarged cross-sectional view of the main part of the threshold illumination hole according to the third embodiment of the present invention. The other configurations are the same as those in the first embodiment.

In the first and second embodiments, the illuminating device 1 is mainly placed on the side of the car so that the user mainly having a lower floor, for example, the user 6 at the landing having a lower floor can easily notice it.
Although the light of No. 1 is emitted, in Example 3, this is to be noticed by the user with a higher floor.

As shown in FIG. 10, the car sill 5 is provided with a car sill illumination hole 21 for guiding light from the back surface of the illumination device 11, and light is emitted from the side of the sill groove 24. Alternatively, the car sill illumination hole 21 that guides the light from the illumination device 11 may be opened so as to reach the bottom of the sill groove 24, and the light may be emitted from below the sill groove 24. A plurality of car sill illumination holes 21 are provided in the width of the doorway of the car room 2.

In the hall sill 8, a hall sill lighting hole 22 having an opening toward the car is formed in the lower part of the reflector 10 in an L shape as shown in the drawing, and the hall sill reflector 23 is provided at the corner thereof.
To provide. Then, light is emitted from under the threshold groove 25.
A plurality of hall threshold lighting holes 22 are provided in the width of the entrance of the hall.

As shown in FIG. 7, when the car sill 5 is lower than the landing sill 8, the light from the illumination device 11 is reflected by the reflecting mirror 1.
Since it illuminates the lower part of 0, the leaked light is reflected by the hall sill reflector 23 through the hall sill lighting hole 22, leaks light to the sill groove 25 of the hall sill 8, and the user 6 notices that the floor is displaced. Let

Example 4. A fourth embodiment of the present invention will be described with reference to FIGS. FIG. 11 is a diagram showing the front of the car room seen from the hall side in the fourth embodiment. Further, FIG. 12 is a view of the case where the door is opened in the fourth embodiment as seen from above, and the car sill 5 and the landing sill 8 are partially removed.

In the first to third embodiments, it was necessary to provide the illumination device 11 with a width that allows a person to go in and out, but in the fourth embodiment, the illumination device 11A is removed from a place where a person goes in and out as shown in FIG. Further, as in the case of the landing, a car-side reflecting mirror 26 made of mirror-finished stainless steel or the like is attached to the entrance / exit on the car side. Other configurations are similar to those of the first embodiment.

As a result, when the photoelectric device 9 detects a floor slip, the light 27 emitted from the illumination device 11A is reflected by the reflecting mirror 10 and the car-side reflecting mirror 26 mounted on the landing side, as shown in FIG. And illuminate the space between the car threshold 5 and the hall threshold 8. In the case of the fourth embodiment, the illumination device 11A can be smaller than the other embodiments.

Example 5. A fifth embodiment of the present invention will be described with reference to FIG. FIG. 13 is a block diagram showing the system configuration of the fifth embodiment of the present invention. In addition,
Other configurations are similar to those of the first embodiment.

In each of the above-described embodiments, when the photoelectric device 9 detects a bed slip, the illumination device 11 only emits light continuously, but in the fifth embodiment, the flicker device 28 is added to detect the bed slip. At this time, the flicker device 28 causes the light emitted from the illumination device 11 to flicker, for example, when the power is turned on or off and the driving current is strong or weak. This allows
The user is more likely to notice a bed sore because his feet flicker.

Example 6. A sixth embodiment of the present invention will be described with reference to FIG. FIG. 14 is a block diagram showing the system configuration of the sixth embodiment of the present invention. In addition,
Other configurations are similar to those of the first embodiment.

In each of the above embodiments, the landing threshold 8 and the car threshold 5
Although the actual amount of floor slip is measured and the illumination device 11 is turned on, in the sixth embodiment, an elevator is another device that can reliably measure the absolute amount of floor slip. From the elevator signal 13, a signal indicating that the elevator is stopped and deviated by more than the allowable error is input to the control unit 14. The control unit 18 issues an illumination lighting command to the illumination control unit 17, and the illumination device 11 emits light.

As a result, the photoelectric device 9 below the car sill 5 is unnecessary, but the fact that the floor is displaced may cause a failure in the floor displacement detecting device.
It is important that 3 is certain. The control unit 14 may be omitted, and the lighting control unit 17 may directly receive the elevator signal 13.
