JPH0570067A - Observation elevator - Google Patents

Abstract

PURPOSE:To allow the people located apart from observation windows to safely enjoy a view in a wide observation visual field when a cage room is crowded by making the floor of the cage room vertically movable, and vertically moving the floor during the lift operation. CONSTITUTION:When a cage room floor vertical movement effective switch is pushed and an operation command is generated from a winder control device, the unfloating state of a double-floor 4 is confirmed, then a voice device 13 is operated to call attention to passengers. A motor 7 is started to lift the moving section 2 of the double-floor 4. When it reaches the fixed height, the mechanical contact is cut off to stop the motor 7. When the deceleration command is generated from the winder control device and an elevator is decelerated, the voice device 13 is operated to call attention to the passengers, the motor 7 is reversely rotated, the mechanical contact is cut off to stop the motor 7, and the floor 4 is returned to the original state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a view elevator car floor.

[0002]

2. Description of the Related Art In the prior art, as described in Japanese Patent Laid-Open No. 81789/81, when the elevator car for a view is crowded with passengers, the car is rotated so that everyone can see the view evenly. I was able to enjoy it.

[0003]

In the above-mentioned conventional technique, the view can be enjoyed by rotating the cab, but it is not taken into consideration by the people in the center and the view cannot be enjoyed. There was a problem. In addition, there is a problem in that the passengers are not warned when the cab rotates, which is dangerous. Further, when the elevator for observation is in the ascending / descending operation, the cab always keeps turning, and no consideration is given to people whose eyes are easy to turn around, and people who are prone to motion sickness. There was also the problem of being there.

An object of the present invention is that everyone can enjoy the view comfortably in the car room of the view elevator.

[0005]

In order to achieve the above-mentioned object, a structure in which a half of the floor on the hall side can be raised and lowered in a car room provided with a view window in the periphery, and a drive unit and a control unit composed of a motor and the like. The control device takes in a command issued from the hoisting machine control device, and the elevator automatically starts moving up and down, and automatically moves the floor.

[0006] Further, when the vertical movement of the floor is started, the passenger is alerted, and the floor surface clearly distinguishes between the movable portion and the non-movable portion.

Further, a floor up / down movement effective switch is provided in the cab room.

[0008]

With the view elevator according to the present invention, a person who is far from the view window such as the center of the cab can extend the view field. Moreover, there is little danger and safety even when the floor is moved up and down. In addition, the device can be disabled depending on the passenger reaction and congestion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a front view of a prospective elevator of the present invention, and FIG. 2 is an internal view of the car of FIG.

1 and 2, the car room 1 has a box-like structure composed of four main side walls, a ceiling surface and a floor surface.

A double floor 4 consisting of a movable part 2 and a non-movable part 3 is installed in this car room 1.

Inside the original floor 5, a drive unit consisting of a gear box 6 and a motor 7 for operating the movable part 2 of the double floor 4 and a double floor controller 8 are provided, and the movable part 2 of the double floor 4 is provided. To be able to move up and down. At this time, the movable part 2 is provided with sufficient columns so that the movable part 2 is not tilted against an unbalanced load of the passengers, all of these columns are driven by a gear box (not shown), and further separated from the side wall to provide a highly stable structure. And
Further, the double floor surface 9 has a different color from that of the movable portion 2 and the non-movable portion 3, and is printed with large characters 10 such as "movable portion" and "non-movable portion". Further, a speaker 12 is arranged beside the indicator 11 in the car room, and the voice device 13 in the double floor control device 8 calls attention to passengers.

Further, the cab floor vertical movement effective switch 14 is installed in the management room of the building.

Next, the operation will be described.

FIG. 3 shows a block diagram of the present apparatus, and FIG. 4 shows a flow chart.

When the cab floor vertical movement effective switch 14 is pressed and an operation command is issued from the hoisting machine control device 15, it is confirmed that the double floor 4 does not float (mechanical contact a is not shown). ) The voice device 13 is operated to call attention to the passenger. Then, the motor 7 is activated to move the movable part 2 of the double floor 4.
Raise. When reaching a certain height, mechanical contact b
Turn off (not shown) to stop. (However, when the elevator decelerates before disconnecting the contact b when the operating time is short, the motor 7 is rotated in the reverse direction to return the floor to the original position. Ignore it, and open the door after the floor returns to its original position.) Eventually, when a deceleration command is issued from the hoist control device 15 and the elevator decelerates, the voice device 13 is operated to call attention to the passengers. The motor 7 is rotated in the reverse direction, the mechanical contact a is cut off, the motor 7 is stopped, and the floor returns to the original position.

Although the above embodiment raises and lowers only one place on the floor, several places may be raised and lowered depending on the size of the car.

[0019]

According to the present invention, even a person who is away from the view window due to congestion in the car room can expand the view field by raising and lowering the floor. In addition, when passengers get on and off,
The moving parts and non-moving parts of the floor surface are clearly visible, and you can enjoy the outlook safely by alerting you when raising or lowering the floor.
