Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a safety device for an elevator door, and more particularly to a device for preventing an accident that an elevator user's hand or the like is drawn into the gap between the door and the doorway frame during the opening operation of the door.

[0002]

[Prior art]

 3 and 4 are views showing a conventional safety device for an elevator door, and FIG. 3 is a view of the entrance and exit of the elevator as viewed from inside the car. FIG. 4 is a sectional view taken along line AA of FIG. In the figure, 1 and 2 are car doors that are automatically opened to the left and right, 3 and 4 are entrance / exit columns, 5 is a transom, 6 is a return panel, 8 is a car operation panel, and 9 is car doors of entry / exit columns 3 and 4. Tape switches 10 installed on the sides 1 and 2 are door pockets.

When the user's hand 11 or the like is mistakenly drawn into the gap 12 between the door 1 and the doorway pillar 3 when the doors 1 and 2 are opened, the hand 11 or the like presses the tape switch 9 to operate, A) Reverse 1, 2 in the closing direction. This prevents the hand 11 or the like from being further drawn into the gap 12. A similar device is also installed on the hall side. In this case, the entrance pillars 3 and 4 and the transom 5 are only three-sided frames, and the structure is similar to that of the car.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional device, the tape switch 9 is activated after the user's hand 11 or the like is caught in the gap 12 and pulled in to some extent, so that the user's hand 11 or the like may be damaged.

[0005]

[Means for Solving the Problems]

 According to the present invention, an illumination lamp is installed on the side of the entrance pillar or three-way frame (hereinafter referred to as the entrance / exit frame) facing the door, and the gap between the door and the entrance / exit frame is illuminated by the illumination light before the door is opened. By doing so, it is configured to notify the customer that the door will open. As a result, the customer can leave the door in advance, so that it is possible to prevent the user's hands from being pulled in.

[0006]

[Embodiment of device]

 According to the first aspect of the present invention, an illumination lamp is installed on the door pocket side of the doorway frame so as to face the door, and the illumination light illuminates the gap between the door and the doorway pillar. Then, the illumination lamp is turned on from a predetermined time before the opening operation of the door is started, and this light leaks into the car through the gap to notify the start of the opening operation of the door and prompt the user to move away from the vicinity of the door. This prevents accidents where the hands, etc. are pulled in.

A second aspect of the present invention is to install an illuminating lamp on the side of the doorway frame opposite to the door pocket so as to face the door. Since this position is facing the gap between the door and the doorway frame and facing the inside of the car, the light directly reaches the user. Therefore, even an illumination lamp such as an LED, which has a comparatively weak light, can sufficiently provide the effect of giving notice to the user that the door opening operation is started.

[0008]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. 1 is a view corresponding to FIG. 4, 20 is an illuminating lamp installed on the door case 10 side of the entrance / exit post 3, 21 is a reflector, and the same reference numerals as those in FIG. 4 denote the same parts. In this embodiment, the illumination lamp 20 is turned on from a predetermined time before the opening operation of the door 1 is started to immediately before the opening operation is started. As a result, the elevator passenger can know in advance that the door 1 will be opened, and thus can wait in a safe position away from the door 1 during the opening operation of the door 1. Further, since the light from the illuminating lamp 20 leaks into the car from the gap 12, the effect of attracting the user's attention to the gap 12 and preventing the hands 11 and the like from being drawn into the gap 12 is great.

Next, another embodiment of the present invention will be described with reference to FIG. In the figure, reference numeral 30 is an illuminating lamp installed at a position facing the door 1 on the side opposite to the door pocket 10 (inside the car) of the doorway pillar 3, and the same reference numerals as those in FIG. In this embodiment, since the mounting position of the illuminating lamp 30 faces the gap 12 between the door 1 and the entrance post 3 and the inside of the car, the light directly reaches the user. Therefore, even a relatively weak light such as an LED may be conspicuous, and a notice effect of the door opening operation start to the customer can be sufficiently exhibited.

In each of the above-described embodiments, the illumination lamps 20 and 30 are installed on the entrance pillar 3 (or 4) facing the door 1 (or 2), but even if installed on the transom 5, the doors 1 and 2 are installed. It is possible to exert the effect as a device for notifying the start of the operation. In each of the above-mentioned embodiments, the lighting time of the illumination lamps 20 and 30 is from a predetermined time before the opening operation of the doors 1 and 2 is started to immediately before the opening operation is started. For example, the effect of calling attention during the opening operation can be achieved. Further, the illumination lamps 20 and 30 may not only be turned on but may be blinked. Further, the device of this embodiment can be installed in the hall as well.

[0011]

[Effect of device]

 As described above, according to the present invention, it is possible to prevent an accident that an elevator user's hand is drawn into the gap between the door and the entrance / exit frame during the opening operation of the door, thereby further improving the safety of the elevator. Can be increased.
