Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to elevators.

[0002]

2. Description of the Related Art The opening and closing of the door of a conventional elevator is automatically opened when a car lands on a predetermined floor,
In most cases, the automatic system is automatically closed by a command from the control device after a certain set time has elapsed. This automatic door is
When a passenger in the car operates the door opening / closing button, the door is closed at a predetermined time.

Therefore, when there are many passengers boarding the car and it takes time to board the car, the passengers inside the car keep pressing the door open button to maintain the door open state. If the hand holding the door open button is released, the door is closed after a predetermined time has elapsed.

[0004]

However, in an elevator that automatically opens and closes the door, if a passenger gets in from the hall just before the door closes, the door and car doors that close close strongly. It may be pushed or pinched.

In order to prevent such a situation, a safety is provided between the landing door and the car door, and the passenger touches the safety sticking out from between the landing door and the car door, so that the closing operation is performed. The landing door and the car door reversely open, but there is a risk that they may be pinched between the left and right landing doors depending on the timing of boarding.

When there are passengers inside the car, it is possible to push the door open button while seeing the user getting into the car from the hall, but when getting into an unmanned car, it is sandwiched by an automated door. There is a risk.

Even if there are passengers inside the car, for example, for passengers behind the operation panel on the left side,
Since the user who enters from the left side as seen from the hall side cannot see the door open button because it is a blind spot due to the three-sided frame or the like, the user may be caught.

Therefore, it is conceivable to install a camera or a photo sensor on the side wall of the hall to detect the movement of the passenger getting in the car. However, this method also corresponds to the passenger getting in the car from an unspecified direction. Not only has to increase the number of cameras and photo sensors, but simply
Even if there is a person who is waiting at the entrance of the hall and waiting with a friend, and there is a person who does not get into the car, there is a possibility that the door may malfunction and the elevator may be delayed in starting.

[0009] Therefore, an object of the present invention is to obtain an elevator which is free from the risk of malfunction and which can prevent the accident of being caught by a user's door.

[0010]

An elevator according to the invention as set forth in claim 1 is provided with an opening / closing display device incorporating a light-emitting body for giving notice of a closing operation of a landing door and a car door on the landing door, the car door or the three-sided frame. It is characterized by that.

Further, the elevator according to a second aspect of the invention is characterized in that a plurality of light emitting bodies emit different light.

Further, the elevator according to claim 3 is
The light emitting element is a light emitting diode.

[0013]

The user who gets in the car from the hall entrance visually recognizes the margin until the closing operation of the hall door and the car door depending on the mode of the light emitted from the light emitter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the elevator according to the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view showing a state where an elevator of the present invention is viewed obliquely from a landing side, and shows a state in which a two-door double-open type car door and a landing door are opened. Also,
FIG. 2 is an enlarged view showing a mounting state of a door opening / closing device, which will be described later in detail, mounted on the elevator shown in FIG. 1.

Of these, FIG. 2 (a) is an enlarged vertical sectional detail view of the elevator door opening / closing display device 9 shown in FIG.
(B) is a right side view of (a), (c) is an AA sectional view of (a), (d) is a front view of (a).

First, in FIG. 1, an elevator hall 7
At the upper end of the gate-shaped three-sided frame 4 provided on the building wall 5, the curtain plate 6 is installed horizontally, and an indicator (not shown) indicating the position and the ascending / descending direction of the car is attached. A sill 8 is shown at the tip of the landing 7, and a landing button 16 is attached to the building wall 5 on the right side of the three-way frame 4.

At the rear of the three-way frame 4, the end of the right hall door 3 of the two-door double-door hall 3 in the open state is shown. At the center of this end, 150c from the floor
The door opening / closing display device 9 of the elevator, which will be described in detail with reference to FIG. 2, is attached to the m position as described later in detail with reference to FIG. 2, and the door opening / closing display device 9 attached to the left hall door 3
It is indicated by a broken line.

A door safety 2 is vertically installed at a rear portion (car side) of the hall doors 3, and a car door 1 is shown further behind the door safety 2. This car door 1 is suspended at the front end of a car 15 shown at the rear.

2 (a), (b), (c), and (d), a square hole 3a is formed at a position 150 cm from the floor surface at the opposite end of the landing door 3 as described above. Has been done.
Into this square hole 3a, a convex portion 10a of a display plate 10 in which one side of a rectangular acrylic resin plate is processed to have a convex shape is inserted, and the convex portion 10a has a shape shown in FIG. 2 (b). The door is sculpted.

On the back surface of the display plate 10, three lens holding plates 11 are adhered and bonded with an adhesive, and these lens holding plates are
Four circular through holes are preliminarily formed in 11 and a lens 16 is previously inserted into each through hole.

A diode housing block 12 is joined to the back surface of each lens holding plate 11, and each diode housing block 12 is formed with a cylindrical hole having a convex cross section. Among them, the light emitting diodes 13g whose globe is green are housed in the cylindrical holes of the diode housing block 12 located at the left end in FIG. 2 (c).

In the columnar hole of the diode housing block 12 located in the center, the light emitting diodes 13y whose globe is orange are housed. Furthermore, FIG.
The diode storage block located at the right end in (c)
Globe red light emitting diode 13r
Are stored respectively.

Other examples of lead wires connected to the respective light emitting diodes 13g, 13y, 13r are respectively connected to door drive circuits of a control panel installed in a machine room provided at the upper end of a hoistway (not shown). .
