JPH04201971A - Cage stop doorway device for elevator - Google Patents

Abstract

PURPOSE:To make the window glass of a floor door and a cage door opaque excluding the time of a cage being in the vicinity of each floor door by using liquid-crystal light-adjusting type glass for the window glass of the elevator floor door and the cage door. CONSTITUTION:Liquid-crystal light-adjusting type window glass 3a-3d are fitted to cage stop entrance doors 1a, 1b and in-cage entrance doors 2a, 2b. A switch 4 and power source 5 are series-connected to the window glass 3a-3d, and the switch 4 is turned on by the signal of an elevator control panel at the time of a cage reaching around a cage stop entrance on each floor to make the window glass 3a-3d transparent. In other cases, the switch 4 is turned off to make the window glass opaque, so that the back face of the cage and the inside of an elevating path are invisible from the cage stop, and the back face of the entrance and the inside of the elevating path are invisible from the cage side.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an elevator hall entrance/exit device.

[Conventional technology]

In the conventional system, when installing window glass on car doors and floor doors for crime prevention, etc., transparent wired glass is used so that the inside of the car can be seen from the landing (Utility Model No. 63-126
Publication No. 376).

[Problem to be solved by the invention]

The above-mentioned conventional technology detects equipment on the outside of the car or in the hoistway except when the car is stopped on the landing floor from the first hot water side.

Steel frames, walls, etc. are visible and it is unsightly. Furthermore, no consideration was given to the fact that when viewed from inside the car, the back of the side door of the elevator in the hoistway, the side wall of the elevator, etc. would be visible while the elevator was running, resulting in an unsightly problem.

The main purpose of the present invention is to make the window glass of the first floor door opaque except when the car is near each floor door, so that the outside of the car and the equipment, steel frames, walls, etc. in the hoistway are not visible. be.

Another object of the present invention is to make the back side of the landing door and the wall of the boarding embankment in the hoistway invisible by making the window glass of the car door opaque except when the car is near the door of each floor. .

[Means to solve the problem]

In order to achieve the above object, the present invention uses liquid crystal dimming glass for the window glass of the elevator floor door.

In order to achieve other objects, the present invention uses liquid crystal dimming glass for the window glass of the door.

[Effect]

According to the present invention, voltage is applied to the window glass of the elevator landing floor door only when the car passes or stops at the floor. Thereby, the window glass of the floor door becomes transparent. In addition, voltage is applied to the window glass of the car door only when the car reaches the door of each floor or when the car is stopped. This makes the window glass of the car door transparent. In other cases, no voltage is applied to the window glass of the landing floor door and the car door, so the window glass becomes opaque.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of an elevator hall entrance/exit device based on the present invention, FIG.
The figure is a sectional view of the door window glass portion of FIGS. 1 and 2.

Boarding entrance doors 1a~lb and high car entrance doors 2a~
2)) Attach the liquid crystal dimming type window glasses 38 to 3d. A switch 4 and a power source 5 are connected in series to the window glass of the lever, and the switch 4 is turned on by a signal from the elevator control panel when the car reaches the entrance of each floor, making the window glasses 38 to 3d transparent. In other cases, by turning off the switch 4, the window glass is made opaque so that the back side of the car and the inside of the hoistway can be hidden from view from the landing, and the back side of the doorway and the inside of the hoistway can be hidden from the car side.

〔Effect of the invention〕

According to the present invention, the inside of the car can be seen from the landing on each floor only when the car is near the door of each floor; otherwise, the interior of the hoistway cannot be seen.

Furthermore, the inside of the hoistway cannot be seen from inside the car except when the car is near the door of each floor.
