  In the conventional door opening extension device as described above, the set door opening extension time, the blinking of the indicator lamp, and the meaning of the color are known to general users, particularly users who use the elevator for the first time. Therefore, the user did not know how many seconds the door closing operation started. For this reason, it was necessary to continue carrying-in / out work etc. while paying attention to the start of the door closing operation, and it was impossible to concentrate on the work. Also, since the conventional door open time extension button is the same type of push button as the door close button, when the door close operation is started unexpectedly and you want to extend the door open time, you may accidentally press the door close button. There was a fear.

  The present invention has been made in order to solve the above-described problems, and is capable of notifying the user of the remaining door opening time more clearly and preventing an erroneous operation of the door closing button. The purpose is to obtain a door opening time extension device.

  The elevator door opening time extension device according to the present invention is provided on the operation panel, and when the elevator door is rotated by an angle corresponding to a desired extension time from the reference position, it rotates in the reverse direction according to the remaining door opening time. A dial operation unit that moves back to the reference position and a time scale unit that is provided on the operation panel and displays the remaining door opening time corresponding to the rotation position of the dial operation unit.

  The elevator door opening time extension device of the present invention uses the dial type operation unit and scale to set the extension time and display the remaining door opening time. It is possible to clearly notify the user and to prevent erroneous operation of the door closing button.

It is a front view which shows the principal part of the operating panel of the elevator by Embodiment 1 of this invention. It is the figure which looked at the part shown in FIG. 1 from the downward direction. It is a perspective view which shows the dial operation part and time scale part of FIG.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
1 is a front view showing an essential part of an elevator operation panel according to Embodiment 1 of the present invention, FIG. 2 is a view of the portion shown in FIG. 1 as viewed from below, and FIG. It is a perspective view which shows a scale part.

  In the figure, a door opening button 2 and a door closing button 3 are provided on an operation panel (car operation panel or landing operation panel) 1. The door opening button 2 and the door closing button 3 are arranged at the same position in the vertical direction of the operation panel 1 with a space between each other in the width direction of the operation panel 1 (left and right direction in FIG. 1). Moreover, the front shape of the door opening button 2 and the door closing button 3 is circular.

  The operation panel 1 is connected to a door control unit 4 that controls opening and closing of a car door and a landing door (not shown). When the door opening button 2 is pressed, a command for opening the car door and the landing door is input to the door control unit 4. Further, when the door closing button 3 is pressed, a command for closing the car door and the landing door is input to the door control unit 4.

  On the outside of the door opening button 2 of the operation panel 1, there is provided a dial operation unit 5 for extending the time when the car door and the landing door are fully open from the normal set time. The dial operation unit 5 can be rotated about an axis perpendicular to the front surface of the operation panel 1. Further, when the dial operation unit 5 is rotated by an angle corresponding to a desired extension time from the reference position (position in FIG. 1), the dial operation unit 5 automatically reverses according to the remaining door opening time until the door closing starts. To return to the reference position.

  Furthermore, the dial operation part 5 has a cylindrical dial body 5a and an arrow-shaped pointer part 5b projecting radially outward from the dial body 5a. The dial body 5a surrounds the door opening button 2. That is, the door opening button 2 is disposed inside the dial body 5a. The rotation operation of the dial operation unit 5 is performed by picking the outer periphery of the dial body 5a with a finger. For this reason, a large number of minute grooves parallel to the axial direction are provided on the outer peripheral surface of the dial body 5a as a slip stopper during operation.

  Around the dial operation unit 5 of the operation panel 1, a time scale unit 6 that displays the remaining door opening time corresponding to the rotational position of the dial operation unit 5 is provided. In this example, the maximum door opening extension time by one operation is 180 seconds, and the scale from 0 to 180 seconds is drawn on the time scale unit 6. When the dial operation unit 5 is at the reference position, the pointer unit 5 b points to 0 second of the time scale unit 6. Moreover, you may make it the display of the pointer part 5b and the time scale part 6 stand out, for example by coloring red.

  A stopper (not shown) that restricts the rotation range of the dial operation unit 5 is provided in the operation panel 1 so as not to rotate outside the set time range (0 to 180 seconds). In this example, the rotation range of the dial operation unit 5 is set to 270 ° from the reference position.

  The door opening button 2 functions only when the dial operation unit 5 is at the reference position, and does not function at positions other than the reference position. That is, the door control unit 4 validates the operation of the door opening button 2 when the dial operation unit 5 is at the reference position, and operates the door opening button 2 when the dial operation unit 5 is rotated to a position other than the reference position. Disable operation.

  The operation mechanism of the dial operation unit 5 has a structure of a mechanical timer using a mainspring spring, although illustration is omitted. When the dial operation section 5 is rotated to an arbitrary time and the door opening extension time is set, the timer functions immediately, and the dial operation section 5 rotates counterclockwise by the restoring force of the mainspring spring (counterclockwise in FIG. 1). Rotate slowly. The timer of the dial operation unit 5 is adjusted so that the duration of the door opening decreases in accordance with the scale of the time scale unit 6. When the pointer 5b reaches 0 seconds, a door closing signal is output from the door control unit 4 to a door motor (not shown), and a door closing operation is started.

  Further, during the extension of the door opening time, the dial operation unit 5 can be further rotated to the extension side to add the extension time. Furthermore, if the work is completed quickly, the door closing button 3 can be pushed to end the door opening extension.

  In such an elevator door opening time extension device, the dial-type operation unit and scale are used to set the extension time and display the remaining door opening time. It is possible to clearly notify the user and to prevent erroneous operation of the door closing button 3.

  That is, when the door is extended, the user can clearly recognize the remaining time visually by reading the scale of the time scale unit 6. Moreover, since it is an analog display, the remaining time can be grasped instantaneously compared to the digital display. Further, the dial method is not a pressing operation but a rotation operation, and the operation method is different from that of the door closing button 3, so that the door closing button 3 is not erroneously operated even when a judgment is made.

The door opening button 2 may be rotated together with the dial main body 5a when the dial operation unit 5 is rotated.
In the first embodiment, the door opening button 2 is disposed inside the dial operation unit 5, but the dial operation unit 5 may be disposed at an interval from the door opening button 2. That is, the dial operation unit 5 may be provided next to the door opening button 2 or above and below the door opening button 2.
Further, the pointer portion may be attached to the operation panel or the door opening button so that the time scale portion rotates together with the dial operation portion.
Furthermore, the front shape of the dial operation unit 5 is not limited to a circle, and may be a polygon, for example. Moreover, the front shape of the door opening button 2 or the door closing button 3 is not limited to a circle, and may be a square, for example.
