Description

  The present invention relates to an elevator door device, and in particular, prevents a hand from being drawn into a gap between doors when the door is opened.

FIG. 9 is a cross-sectional view of an elevator apparatus showing a conventional elevator door apparatus. In the figure, 1 is an elevator car, 2 is a car doorway column provided on both sides of the car 1 entrance, 3 is a car door that opens and closes the car 1 door, 4 is a landing doorway, and 5 is a landing doorway 4 The provided hall three-way frame 6 is a hall door that opens and closes the hall entrance 4.
The elevator car door 3 and the landing door 6 are configured to open in conjunction with each other, and between the car door 3 and the car doorway pillar 2 and between the landing door 6 and the landing three-way frame 5, the car door 3. And the landing door 6 is set with a gap so that it can move.
Since the conventional elevator door device is configured as described above, for example, as shown in FIG. 10, the landing door 6 is opened with an arrow while the hand is touching the movable landing door 6. When moving in the direction, as shown in FIG. 11, there is a problem that a hand is drawn into a gap between the landing door 6 and the landing three-way frame 5. In particular, the movable side door 6 has a structure in which the upper end is suspended and supported by a door hanger, the lower end is slid and guided in a sill groove, and a thin steel plate is bent. The gap between the landing door 6 and the landing three-way frame 5 is likely to be increased. Therefore, there is a problem that when the hand is drawn, the gap is further widened, and the gap into which the hand is drawn is further enlarged. The same applies to the case between the movable car door 3 and the car doorway column 2.

  Also, as a conventional technique, when a foreign object such as a passenger's fingertip abnormally approaches the gap with the relative displacement member when the sliding door is opened, the cover plate is elastically deformed by the foreign object and presses the operating body to operate the detector. Thus, a detection device has been proposed that is pulled in when the door of the elevator that controls the opening operation of the sliding door is abnormal (see, for example, Patent Document 1). As another conventional technique, a photoelectric switch that allows irradiation light and reflected light to pass along the vertical direction is arranged at a landing-side corner portion formed by the front side wall surface of the slide door and the vertical end surface of the vertical frame. In addition, a rubber tube (optical path cover) that shields the irradiated and reflected light and its surroundings as an optical path is arranged along the vertical direction of the vertical frame, and foreign objects abut or press against the rubber tube during the door opening operation. Then, an elevator door pull-in prevention device has been proposed in which the rubber tube is deformed to block the irradiation light or reflected light and the photoelectric switch detects and stops the sliding door opening operation (for example, Patent Documents). 2).

JP 2004-18261 A JP 2007-91385 A

  In the detection device that is pulled in when the elevator door is a conventional technology, the cover plate is elastically deformed by a foreign substance to press the operating body, the detector is operated, the control device is activated to stop the sliding door open, Since the control at the time of abnormalities such as reversing the sliding door is performed, if the detector is inoperative for some reason, the finger could not be prevented from being pulled. In addition, other conventional elevator door pull-in prevention devices require components such as a photoelectric switch and a rubber tube (optical path cover), and the photoelectric switch is inoperative for some reason. In some cases, the finger could not be prevented from being pulled in.

  The present invention has been made to solve the above-described problems, and does not rely on mechanical or electrical detectors, photoelectric switches, or the like for pulling in when the door is opened. The present invention provides an elevator door device in which the user pulls out his / her hand from the door and promotes the pull-out operation by recognizing that the user has been pulled in.

  The elevator door device according to the present invention includes a car doorway column provided at a car doorway, a car door that opens and closes the car doorway, a landing three-way frame provided at the landing doorway, and a hall that opens and closes the hall doorway. The door side of the car doorway column and the car doorway column are formed by cutting out the corners straddling the surface of the car doorway side and the surface of the car doorway side, and the car doorway column. A car-side retracted cognitive body made of an elastic body that is drawn into the car side and is arranged so as to always cover the surface of the car entrance / exit side of the space for cognition. When a pull-in occurs in the gap between the door and the car entrance / exit pillar, the car is pulled in and pushed inside the recognition space to displace it. Once written, by increasing inwardly deformed, but for hitting the retracted surface of the squirrel entrance columns are hidden inside through cognitive space portion is retracted cage-side recognized the drawn as the next step.

  In addition, the landing side recognition space part formed by notching the corner part straddling the door side surface of the landing three-way frame and the surface on the landing doorway side, and provided in the landing three-way frame, the landing side pull-in It is provided with a landing-side-recognized body made of an elastic body so as to always cover the surface on the landing entrance side of the recognition space, and the landing-side recognized body is a gap between the landing door and the landing three-way frame When it is pulled in, it is pulled into the landing side and pushed into the recognition space to displace it. In this case, the next-stage pull-in is recognized by hitting the pull-in surface of the landing three-way frame that is drawn into the hall and concealed through the recognition space.

  In addition, the car-side drawn-in recognition body is a car-side first drawn-in recognition body made up of an elastic body that is drawn into the car side and is arranged so as to always cover the car entrance / exit side surface of the recognition space, and the car-side first. When it is drawn in the gap between the car door and the car doorway column, it is pulled in and integrated with the cognitive body. When the car side is pulled in and the cognitive body is pushed inward and displaced, it moves and deforms in conjunction. Then, it hits the pull-in surface of the car entrance / exit pillar and extends toward the car door side, and the car side second draws in the gap between the car door and the car entrance / exit pillar, and consists of a recognition body.

  Further, the landing side drawn-in recognition body includes a landing-side first drawn-in recognition body made of an elastic body that is drawn into the landing side and always covers the surface on the landing entrance side of the space for recognition, and the first on the landing side. It is drawn in and integrated with the recognition body, and when it is pulled into the gap between the landing door and the landing three-way frame, when the landing side is pulled in and the recognition body is pushed inward and displaced, it moves and deforms in conjunction. Then, it hits the pull-in surface of the landing three-way frame and extends toward the door side of the landing, and is composed of a second landing-side recognition body that closes the gap between the landing door and the landing three-way frame.

  In addition, an additional member is retrofitted to the door side of the car entrance / exit side of the car entrance / exit column of the existing elevator, whereby the car side is drawn to form a recognition space.

  In addition, an additional member is retrofitted to the door side of the counter landing on the surface of the landing three-way frame of the existing elevator, thereby forming a space for recognition.

  According to the present invention, the pull-in at the time of opening the door is not dependent on a mechanical or electrical detector, a photoelectric switch, etc. This can be prevented beforehand by the two-stage structure.

Reference numeral 7 denotes a car side formed by cutting out about 1/2 each of the corners straddling the surface 2a of the car doorway 2 of the car doorway column 2 and the surface 2b of the car doorway column 2 on the car doorway side. It is provided so that it may extend in the up-down direction of the car entrance / exit pillar 2 in the space for use. This car-side drawn-in recognition space portion 7 includes a car entrance / entrance 2 and a car entrance / exit surface 2c of the car entrance / exit post 2 drawn in parallel with a predetermined distance from the surface 2a of the car entrance / exit post 2 on the car door 3 side. The column 2 is formed by two L-shaped surfaces including a pull-in surface 2d of the car entrance / exit post 2 drawn in parallel with a predetermined interval from the surface 2b on the car entrance / exit side of the post 2. 8 is provided so that the attachment side is fixed to the drawing-in surface 2c of the car entrance / exit post 2 which is drawn into the car side and forms the recognition space portion 7 so as to be drawn into the car side and cover the entire car entrance / exit surface of the recognition space portion 7. This is a first L-shaped car side first drawn-in cognitive body. The car-side first drawn-in recognition body 8 is composed of an elastic body that is easily deformed. Note that the pull-in surface 2d of the car doorway column 2 that is drawn into the car side and forms the recognition space portion 7 is normally drawn into the car side and is covered with the cognitive body 8, so that it is hidden inside and cannot be seen. However, when the hand is pulled in, the car side second pulls in and forms a cognitive body, which is composed of a rigid steel plate. That is, when the door is opened, the pull-in surface 2d of the car doorway column 2 that constitutes the car body second retracted body is pulled between the car door 3 and the car doorway column 2 so that the car side first When the hand is further drawn after being pulled in and the recognition body 8 is displaced, the hand hits the pulling surface 2d of the rigid car entrance / exit post 2 to let the passenger recognize that it has been pulled in and pull out the hand. By encouraging such an operation, it is possible to prevent the device from being pulled in by itself without relying on a mechanical or electrical detector, a photoelectric switch, or the like.
Further, 9 is a landing side formed by cutting out about 1/2 each of the corner portions over the surface 5a on the landing door 6 side of the landing three-way frame 5 and the surface 5b on the landing doorway 4 side of the landing three-way frame 5. It is drawn in and is provided so as to extend in the vertical direction of the landing three-way frame 5 in the space for recognition. The space 9 for recognizing the landing side is composed of a pull-in surface 5c of the landing three-way frame 5 which is pulled in substantially parallel to a surface 5a on the landing door 6 side of the landing three-way frame 5 at a predetermined interval, and the landing three-way The frame 5 is formed by two L-shaped surfaces including a drawing surface 5d of the landing three-way frame 5 which is drawn in parallel with a predetermined interval from a surface 5b on the landing entrance 4 side. 10 is attached to the drawing surface 5c of the landing three-way frame 5 which is drawn into the landing side and forms the recognition space portion 9, and is provided so as to cover the entire landing entrance 4 surface of the landing space portion 9 being drawn into the landing side.

The landing surface 5d of the landing three-way frame 5 that is drawn into the landing side and forms the recognition space portion 9 is normally drawn into the landing side and is covered with the recognition body 10, and is therefore hidden inside and cannot be seen. However, when the hand is pulled in, the landing side second pulls in and constitutes a recognition body, which is composed of a steel plate having rigidity. That is, the pull-in surface 5d of the landing three-sided frame 5 constituting the recognition body on the second landing side is drawn in between the landing door 6 and the landing three-way frame 5 when the door is opened, When the hand is further drawn after being pulled in and the recognition body 10 is displaced, the hand hits the pulling surface 5d of the rigid landing three-way frame 5 to recognize that the passenger has been pulled in and pull out the hand. By encouraging such an operation, it is possible to prevent the device from being pulled in by itself without relying on a mechanical or electrical detector, a photoelectric switch, or the like.

Next, the pull-in prevention operation when the door is opened by the elevator door device of the present invention will be described with reference to FIGS. Here, the case where a hand is drawn between the landing door 6 and the landing three-way frame 5 will be described, but the same applies to the case where a hand is drawn between the car door 3 and the car doorway pillar 2.
In the initial state when the door is opened by the elevator door device, as shown in FIG. 3, when the hand is drawn between the landing door 6 and the landing three-way frame 5, the L-shaped landing-side first pull-in is performed. The recognition body 10 is pushed and displaced in a V shape, and the hand is caught between the landing door 6 and the landing side first pulling and the recognition body 10, so that it is the initial stage that the hand has been drawn into the passenger. By encouraging the action of pulling out the hand here, it is possible to prevent pulling in by itself without relying on a mechanical or electrical detector, a photoelectric switch, or the like. At this time, even if the first drawn-in recognition body 10 made of a soft elastic body comes into contact with the hand, there is no injury. In the state where the hand is further pulled in, as shown in FIG. 4, a rigid landing three-way frame concealed in the L-shaped landing-side first pull-in side recognition unit 10 is pushed and greatly deformed. Since the hand hits the drawing surface 5d, the passenger can recognize that the hand has been drawn in as the next stage, and by prompting again the action of pulling out the hand, the machine It is possible to prevent it from being pulled in by itself without relying on an automatic or electrical detector, a photoelectric switch, or the like by using a two-stage structure. Here, since the drawn-in hand can move to the first drawn-in recognition body 10 made of a soft elastic body, that is, the space on the door side of the counter landing, it generates a force that displaces the movable landing door. In this case, the space to be pulled in is not enlarged, so that the pulling in can be reduced.

It has become. In addition, although the case where the landing side 1st drawing-in recognition body 11 and the landing side 2nd drawing-in recognition body 12 were provided in the space part 9 for recognition by being pulled in at the landing side was explained here, the space for recognition is drawn by the car side. Of course, the car side first drawn-in recognition body and the car-side second drawn-in recognition body are also provided in the part 7.

Next, the pull-in preventing operation when the door is opened by the elevator door device of the present invention will be described with reference to FIGS. Here, the case where a hand is drawn between the landing door 6 and the landing three-way frame 5 will be described, but the same applies to the case where a hand is drawn between the car door 3 and the car doorway pillar 2.
As shown in FIG. 5, when the landing door 6 moves in the opening direction with the hand placed on the landing door 6, a hand is eventually drawn between the landing door 6 and the landing three-way frame 5, as shown in FIG. 6. First, the landing side first pull-in recognition body 11 comes into contact with the hand, and the landing side first pull-in recognition body 11 moves in the opening direction of the landing door 6. It is possible to let the passenger recognize that the hand has been pulled in during this movement as an initial stage, and by relying on a mechanical or electrical detector, photoelectric switch, etc. Therefore, it is possible to prevent it from being pulled in by itself. When the landing side first pull-in and the recognition body 11 are further pushed in, the landing side second pull-in and the recognition body 12 are pushed by the pull-in surface 5d of the landing three-way frame 5, and the tip part is moved to the landing door 6 side by the elastic force. It is displaced so as to extend, and the gap between the landing three-way frame 5 and the landing door 6 is closed, and the space to be drawn is eliminated. When the landing side first pull-in and the recognition body 11 are pushed in, as shown in FIG. 7, the landing side first pull-in and the recognition body 11 fall and deform, so that the landing side second pull-in and the recognition body 12 are handed. Will hit. This allows the passenger to recognize that the hand has been pulled in as the next stage, and by further encouraging the action to pull out the hand here, the mechanical or electrical detector, photoelectric switch, etc. It is possible to prevent it from being pulled in on its own without relying on it. Here, since the drawn-in hand comes into contact with the first drawn-in recognition body 11 and the second drawn-out recognition body 12 made of a soft elastic body, the touched hand is not injured.
