Abstract

<P>PROBLEM TO BE SOLVED: To provide a monitoring device for an elevator car having an inner monitoring device superior in visibility, by intuitively knowing the doorway direction of a picture reflected by a TV monitor using few components, even in a state where an operation panel operator cannot confirm the boarding-alighting of a back face side door in a state such as being full in a car, in a two-way doorway elevator. <P>SOLUTION: The two-way doorway elevator is constituted by installing a TV camera 6 arranged in the ceiling so as to reflect both doorways, a TV monitor 4a installed so that the front side doorway is reflected in the upper part of an operation panel 3a arranged in the vicinity of the front side doorway, the TV monitor 4a in an upper part of an operation panel 3b arranged in the vicinity of the back face side doorway arranged in the opposite direction of the doorway, and a TV monitor 4b so that the back face side doorway is reflected on the upper part by being vertically oppositely installed. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

The present invention facilitates the situation on the back when the operator operates the operation panel installed in the vicinity of the entrance opposite to the entrance where the elevator user gets on and off in an elevator having two or more entrances. The present invention relates to a monitoring device for an elevator car that can be confirmed in a safe manner and can be used safely.

In general, it is known that a mirror is installed to grasp the situation on the back side.

Further, as an example using a television camera, as described in JP-A-8-157155, a television camera is attached to the ceiling and a television monitor is attached to a side plate opposite to the entrance / exit.
JP-A-8-157155

However, when the mirror is applied to a two-way entrance / exit elevator, only a small mirror can be attached to the upper part of the entrance / exit, resulting in poor visibility. Moreover, according to said invention, since the television camera has faced the entrance, the back surface of a television camera is not reflected on a television monitor. In addition, when applied to a two-way elevator, two television cameras and a television monitor connected to each television camera are required.

An object of the present invention is to provide an elevator car monitoring device that has fewer components in a two-way doorway elevator, and has a monitoring device that can intuitively recognize the entrance / exit direction of images projected on a TV monitor and has good visibility. It is in.

In order to achieve the above object, the present invention provides an elevator car equipped with a monitoring device that allows an operator of the elevator cab to check the rear doorway, so that the checking means reflects both doorways of the two-way doorway elevator. A TV monitor installed on the ceiling and a TV monitor installed on the upper part of the operation panel near the front doorway so that the front doorway is reflected above, and a rear doorway provided in a direction opposite to the above doorway The TV monitor is attached to the upper part of the operation panel installed in the vicinity of the TV monitor so that the above-mentioned TV monitor is installed upside down and the rear side entrance is projected upward.

According to the present invention, even in a situation where the car is crowded and the operator of the operation panel cannot turn around, it is possible to check the situation of the rear entrance by simply moving the line of sight to the upper part of the operation panel, and efficiently closing the door. The button can be operated, and the elevator can be operated efficiently by shortening the opening time of the useless door. In addition, by using a TV monitor that displays the same image and mounting one upside down, the elevator car monitoring device can be provided at low cost with few components without the need for equipment such as reversing the image. can do.

FIG. 1 is a side sectional view of an elevator car equipped with a front TV monitor 4a, a rear TV monitor 4b, and a TV camera 6 attached to the ceiling 5 in a two-way elevator. FIG. 2 is a TV camera of FIG. 3 is a cross-sectional view taken along the line AA in FIG. 1, FIG. 4 is a detailed view of the video image of the TV monitor 4a in FIG. 3, FIG. 5 is a cross-sectional view taken along the line BB in FIG. FIG. 6 is a detailed video view of the television monitor 4b of FIG.

In FIG. 1, a front side door 1a, a front side plate 2a, and a front side operation panel 3a attached to the side plate are provided, and a front side TV monitor 4a is attached to the upper part of the front side and within a line of sight. A back side door 1b provided on the side facing the door, a back side plate 2b, and a back side operation panel 3b attached to the side plate are provided. A television monitor 4b was attached. A TV camera 6 is attached to the ceiling 5 so that the floor surface is in front and the above two entrances can be photographed, and the photographed video is connected to the television monitors 4a and 4b by the wiring 7. Send. A video taken by the TV camera 6 is shown in FIG. In FIG. 3, the TV monitor 4a installed immediately above the front side operation panel 3a is installed so that the front side entrance 1a is reflected upward as shown in FIG. 4, and the same as the TV monitor 4a in FIG. The rear TV monitor 4b is installed directly above the rear operation panel 3b so as to be upside down with respect to the TV monitor 4a. The rear TV monitor 4b has a rear door as shown in FIG. The structure is such that 1b is displayed above.

It is side surface sectional drawing of the elevator car which installed the monitoring apparatus. It is a figure which shows the picked-up image of the television camera 6. FIG. It is AA sectional drawing of FIG. It is a figure which shows the image | video of the television monitor 4a of FIG. It is BB sectional drawing of FIG. It is a figure which shows the image | video of the television monitor 4b of FIG.
